key: cord- -nhpjvgt authors: ricardo, jose w.; lipner, shari r. title: considerations for safety in the use of systemic medications for psoriasis and atopic dermatitis during the covid‐ pandemic date: - - journal: dermatol ther doi: . /dth. sha: doc_id: cord_uid: nhpjvgt coronavirus disease (covid‐ ), is responsible for at least , , cases and , deaths as of april , . psoriasis and atopic dermatitis are common, chronic, inflammatory skin conditions, with immune dysregulation as a shared mechanism; therefore, mainstays of treatment include systemic immunomodulating therapies. it is unknown whether these therapies are associated with increased to covid‐ susceptibility or worse outcomes in infected patients. in this review, we discuss overall infection risks of non‐biologic and biologic systemic medications for psoriasis and atopic dermatitis, and provide therapeutic recommendations. in summary, in patients with active infection, systemic conventional medications, the jak inhibitor tofacitinib, and biologics for psoriasis should be temporarily held until there is more data; in uninfected patients switching to safer alternatives should be considered. interleukin (il)‐ , il‐ / and il‐ inhibitors are associated with low infection risk, with il‐ and il‐ favored over il‐ / inhibitors. pivotal trials and postmarketing data also suggest that il‐ and il‐ blockers are safer than tnf‐blockers. apremilast, acitretin and dupilumab, have favorable safety data, and may be safely initiated and continued in uninfected patients. without definitive covid‐ data, these recommendations may be useful in guiding treatment of psoriasis and atopic dermatitis patients during the covid‐ pandemic. this article is protected by copyright. all rights reserved. severe acute respiratory syndrome coronavirus (sars-cov- ) is a novel human coronavirus, with , , confirmed cases of coronavirus disease (covid- ) and , deaths worldwide (april , ). it was declared a pandemic by the world health organization. an overall case fatality rate of . % has been reported, however, inaccuracies may exist because those who are asymptomatic or suffer from mild disease may never receive confirmation. psoriasis and atopic dermatitis (ad) are common, chronic, inflammatory skin diseases, affecting - % of the general population and % of adults in the united states (us), respectively. , disease mechanisms are multifactorial, with immune dysregulation important for both conditions, and mainstays of treatment immune-modulation. systemic therapy is preferred for psoriasis treatment in patients with body surface area> %, involvement of sensitive areas or topical therapy failure. systemic treatment is recommended for ad patients with severe disease or recalcitrant to topical therapy. immunocompromised patients are highly vulnerable to infections, which is particularly concerning in the context of the covid- pandemic. in this review, we summarize the current literature regarding overall infection risks with systemic immunomodulating agents for psoriasis and ad, and provide evidence-based treatment recommendations during the covid- pandemic. systemic corticosteroids are immunosuppressive medications used to treat ad flares, but very rarely psoriasis. they have been shown to increase infection risk. in a systematic review of studies on ad children (n= , ) treated with systemic corticosteroids ≥ days, infection rate was . %, with associated deaths. in a meta-analysis of corticosteroid use in patients with influenza pneumonia ( studies, n= ), compared with placebo, corticosteroids were associated with higher mortality, longer intensive care unit length of stay and a higher rate of secondary infection. therefore, oral corticosteroids should be avoided, weighing the risks of disease flare vs. sars-cov- infection, to prevent covid- susceptibility. before discontinuation, dose tapering may be considered to avoid a negative effect on respiratory symptoms. methotrexate and cyclosporine are amongst the most frequently used systemic medications for psoriasis and ad, with both associated with increased infection rates. there was a % higher overall infection risk with cyclosporine vs. methotrexate in the biobadaderm registry (spanish registry of adverse events for biological therapy in dermatological disease) including psoriasis patients. in a head-to-head comparison of methotrexate (n= ) versus cyclosporine (n= ) in moderate to severe ad adults, infections rates were % and %, respectively. while methotrexate and cyclosporine are associated with decreased infection rates and favored over treatment with systemic corticosteroids, their impact on susceptibility to/severity of covid- is unknown and, if essential, precautions should be taken to avoid infection. of interest, cyclosporine has anti-coronavirus activity in vitro, but the effect in humans is unknown. the systemic retinoid, acitretin, is anti-inflammatory and inhibits cell differentiation; it is food and drug administration (fda)-approved for psoriasis. it does not suppress the immune system to the extent of the other conventional treatments for psoriasis. in an observational cohort study, there was no increased rate of overall serious infections among acitretin-treated psoriasis patients vs. methotrexate; acitretin increased risk of cellulitis compared to methotrexate (propensity score-adjusted hazard ratio [hr], . ; % ci, . - . ), possibly due to skin fragility and staphylococcus aureus colonization. therefore, acitretin has not shown increased viral/respiratory infection risk and can be safely used during the pandemic. retinoids have been shown to inhibit human herpesvirus eight replication, their effect on sars-cov- remains to be established. this article is protected by copyright. all rights reserved. azathioprine is used off-label in the us for ad treatment in patients recalcitrant or who have contraindications to cyclosporine and methotrexate. in ad children treated with azathioprine, there were no associated infections. in a double-blind, placebo-controlled, crossover study of ad adults treated with azathioprine, there were five cases of upper respiratory infections (uris) ( %), two cases folliculitis ( %), and one report each impetigo ( %) and sore throat ( %). in a retrospective analysis of , systemically-treated adults with ad (six months), there were increased risks of serious and opportunistic infections with azathioprine (rr= . ) and prednisone (rr= . ) compared with methotrexate, with a reduced risk with cyclosporine (rr= . ). therefore, azathioprine may increase susceptibility to infections, and if essential, exposure to covid- should be minimized. apremilast, an orally administered phosphodiesterase four inhibitor is fda-approved for moderate to severe plaque psoriasis and has been used off-label for ad. [ ] [ ] [ ] although it does modulate immunologic cascades, this pathway does not seem to particularly increase susceptibility to infection. in a pooled safety analysis of two randomized, controlled trials (rcts) involving psoriasis patients treated with apremilast (n= ), uris and nasopharyngitis occurred in . % and . % of patients, respectively; serious infections (urinary tract infection n= ; appendicitis n= ; pneumonia= ) occurred in . %. furthermore, in an observational cohort study including systemically treated psoriasis patients, overall serious infections were decreased with apremilast vs. methotrexate (hr, . ; % ci, . - . ). thus, apremilast seems to be a safe alternative for uninfected psoriasis patients during the pandemic, but specific covid- data is needed. data regarding infection risks of nonbiological therapies for psoriasis and ad is summarized in table . biologic medications are widely used for psoriasis and ad patients, with limited data regarding infection risk. since biologics inhibit immune-mediated pathways involving specific cytokines, there is at least theoretical risk of increased susceptibility to and severity of infection. a common reason for discontinuation of biologics is infection. among the targeted cytokines for these biologics, tumor necrosis factor-alpha (tnf-α) plays a crucial role in the immune response against intracellular pathogens and formation of granulomas, and interleukin (il) - and il- are involved in cell-mediated immunity by inducing interferon-γ. il- also induces t-helper cell differentiation and il- secretion, fundamental in providing immunity against bacteria, viruses, fungi and parasites. , il- and il- play key roles in the immune response against helminth infections. five classes of biologic therapies are used for psoriasis or ad: tnf-α inhibitors (table ) , il- inhibitors, an il- / inhibitor, il- inhibitors, an il- / inhibitor, and a janus kinase (jak) inhibitor (table ) . this article is protected by copyright. all rights reserved. anti-tnf-α therapies inhibit a crucial immunological pathway, therefore an immunosuppressive effect and increased infection risk are expected. there is an fdarequired black box warning of infection susceptibility. however, assessing infection risk is challenging because rcts are often not adequately powered to detect rare events and ineligibility criteria may exclude up to % of real-world patients. certolizumab increased risks of all infections, uris and nasopharyngitis by %, % and %, respectively. additionally, anti-tnf-α therapy is associated with latent tuberculosis reactivation, even with chemoprophylaxis; infliximab is associated with increased risk of herpes zoster. , therefore, based on available data, anti-tnf-α biologics should be held similarly, an % increased risk in overall infections with secukinumab was reported based on pivotal trials, with most attributable to yeast infections; uris were increased slightly for secukinumab, but not for ixekizumab or brodalumab. since il- plays an important role in immunological response against candida infections, there is a theoretical increased risk of yeast infections with anti-il therapies. in a pooled analysis from phase two and three clinical studies on , psoriasis patients treated with secukinumab mg (n= , ), mg (n= , ) and etanercept (n= ), candida infections were reported in . %, . % and . % of subjects, respectively. all infections were mild, resolved spontaneously or responded to standard treatment, without causing treatment discontinuation. overall, increased infection risk has been shown with il- inhibitors, but yeast infections may constitute a large proportion of that increase; uris are particularly uncommon. therefore, il- inhibitors may be safely prescribed and continued, unless the patient is symptomatic or positive for sars-cov- . ustekinumab inhibits il- and il- , with il- playing an important role in protection against viral infections. , , however, no increased susceptibility to infection with ustekinumab has been reported. in a pooled analysis of four phase two/three studies of , this article is protected by copyright. all rights reserved. contrary to il- / inhibitors, anti-il- therapies do not target il- , and il- plays a key role fighting viral infections. , reduced risks of salmonella, candida and mycobacterium infections were seen in il- p -targeted vs. il- / p -targeted animal models. - nonetheless, rcts on il- inhibitors have shown conflicting results regarding infection risks. in a phase iii, double-blinded, placebo-controlled study on psoriasis patients randomized to treatment with guselkumab, adalimumab or placebo, overall, candida, and serious infections, occurred at comparable rates across treatment groups. in risankizumab-treated psoriasis patients, there was increased overall infection risk in two this article is protected by copyright. all rights reserved. phase three studies. the most common infections were uris, urinary tract infections and influenza. two cases of latent tuberculosis were reported in the risankizumab group; both patients tested negative at baseline. data assessing infection risk with tildrakizumab is sparse. lebwohl et al reported an increase in nasopharyngitis ( %) with tildrakizumab compared with placebo. risk, however, is low and comparable to placebo. therefore, based on available data, il- inhibitors may be continued/initiated, unless the patient is symptomatic or positive for sars-cov- . tofacitinib is a small molecule inhibitor of tyrosine kinases of the janus family, preferentially jak and jak , downregulating cytokines crucial for lymphocyte development; therefore, there is potential for increased risks of intracellular bacterial and viral infections. it has been hypothesized, nonetheless, that fluctuations in plasma levels of jak inhibitors throughout the day may preserve immunogenicity against infectious pathogens. tofacitinib carries an fda-required black box warning for serious infections. in one placebo-controlled phase three trial of patients with psoriatic arthritis, randomized to treatment with -mg or -mg tofacitinib, adalimumab, or placebo, nasopharyngitis (in %, % and %, respectively) and uris (in %, %, and %, respectively) were the most common adverse events. there were three cases of serious infections (influenza, appendicitis and pneumonia) and four cases of herpes zoster in the tofacitinib-treated group. similarly, in two randomized, placebo-controlled studies of and psoriasis patients treated with tofacitinib -mg and -mg, respectively, nasopharyngitis and uris were the most common infections, and serious infections (pneumonia, herpes zoster and erysipelas in the -mg group; and appendicitis, pneumonia and pyelonephritis in the -mg group) were reported in tofacitinib-treated patients. furthermore, herpes zoster was reported in tofacitinib-treated patients versus none in the placebo groups. thus, tofacitinib has an association with increased infection risk in psoriasis/psoriatic arthritis patients. tofacitinibtreated patients may be more susceptible to covid- , strict protective measures are recommended to minimize viral exposure. dupilumab targets il- and il- , elements of the type two immune response. as type one and type two immune responses cross-regulate each other, suppression of type one immunity can potentially facilitate uncontrolled or persistent viral and bacterial infections. nonetheless, dupilumab has been associated with a reduced infection rate in ad patients. a pooled analysis of seven rcts on dupilumab-treated ad adults showed a decreased risk of serious infections, skin infections and herpes infections (eczema herpeticum or herpes zoster) in the dupilumab groups compared with placebo. furthermore, by also treating asthma, dupilumab may theoretically decrease risk for covid- infected patients for severe respiratory disease. therefore, current evidence suggests continuing and initiating dupilumab treatment in ad patients during the covid- pandemic. it is difficult to make definitive conclusions about susceptibility to sars-cov- infection in psoriasis or ad patients on systemic treatments, solely based on general infection risk data. furthermore, the majority of studies included patients with mean age of approximately years; therefore, these recommendations may not be applicable to older individuals, who on average have higher covid- associated mortality. there is also a potential role for some of these medications as treatments of covid- but this remains largely unknown. in we suggest the following algorithms for treatment of psoriasis and ad during the covid- pandemic (figures , ) . this article is protected by

exanthematous, urticarial rashes and facial ulceration in affected infants may born from infected mothers ( , ) . hydroxychloroquine-induced rashes solely or in combination with other therapies, are responsible for the main cutaneous drug reactions especially generalized pustular eruptions ( ) ( ) ( ) . there are some secondary covid- related dermatoses like incidence of an acute new dermatologic entity for a limited time period that could be stress-related (e.g. herpes simplex, herpes zoster, alopecia areata ad etc…) or physical-environmental-related (e.g. contact dermatitis, acute urticaria…) or presence of a new dermatoses which have tendency to become chronic, like telogen-effluvium, various types of dermatitis, neurocutaneous or psychocutaneous disorders. in the pandemic, some preexisting chronic dermatoses may become poorly-controlled or aggravated by the stress, irregular visits, treatment interruptions, delayed therapies, physical and environmental situations like wearing masks and latex gloves, frequent washing and disinfectants, excessive sweating and etc ( ) . dermatologic visits and cosmetic or elective surgical procedure have been affected largely by a decreasing manner during pandemic ( ) . adherence to personal and social hygiene strategies, social isolation and distance are the rules of pandemic for better controlling any situations and the role of teledermatology is really important in this area regarding educational and therapeutic issues ( ) . in dermatology, one of the most important concerns in the pandemic setting is the manner of disease management especially in the case of patients under treatment with immunosuppressive immunomodulators. non-infected non-at risk patients do not need to any change in their therapeutic protocols but at-risk patients or who suspected to being infected (like having suggestive symptoms) need altering drug regimen as dose reduction, increase dose interval or transient stop of drug usage for at least weeks. it is not any doubt that, every patient with an active corona virus infection should discontinue systemic biologic or non-biologic immunosuppressive for at least month or completely being symptom-free. a more severe covid- course is usually predictable in the setting of dermatologic diseases which are treating by systemic immunomodulators. presence of any comorbidities related to underlying dermatologic disorder (like older age, metabolic syndrome and vital organ dysfunctions especially respiratory and cardiovascular involvements that may be seen in psoriatic or atopic patients or who with hidradenitis suppurativa, immunobullous or collagen vascular disorders), is associated with poorer outcomes in the case of being infected by covid- . some studies suggested that more sever skin conditions are at risk for higher rate of pneumonia and symptomatic respiratory involvement. in future vaccination of these groups of patients is one of priority issues. it seems that in patients with any severe and serious dermatologic disorders, under treatment with systemic agents, if there is not any suspicion about concurrent infection or any high risk exposures, not only it is not recommend to cessation therapy but only emphasize that these drugs could prevent disease flare-up and control cytokine storm that both in a negative direction, affect the covid- course ( ) ( ) ( ) ( ) ( ) ( ) ( ) ( ) . one of the most important perspectives in the field of dermatology is to approach patients with any documented skin or mucosal disorders especially who are using immunomodulators and now are affected by covid- . for consensus and more exact expert recommendations in this group of patients, we need data gathering about people who were in this situation and know more about what experience say about dermatologic disease course, covid- course and manner of managing both conditions in the best possible way? so in this systematic review we focused on specific patient groups with a dermatologic disorder (usually under therapy) that concomitantly have been infected by the new corona virus and summed up their data in all aspects of underlying and infectious disease course and management. this study is implemented according to the prisma (preferred reporting items for systematic reviews and meta-analyses) statement. inclusion criteria comprised all studies about patients with any documented skin or mucosal disorders especially who were using immunomoduators and now were affected by covid- . the exclusion criteria consisted of all publications not meeting the above contents and non-english literature. we searched databases of pubmed, scopus, google scholar, medscape and cebd coronavirus dermatology resource of nottingham university (https://www.nottingham.ac.uk/). our key words were ( "covid- " ) or ( "severe acute respiratory syndrome coronavirus " ) and ( "skin" ) or ( "skin diseases" ) or ( "skin manifestations" ) or ( "dermatology" ) or ("skin and connective tissue diseases" ) or ( "eczematous" ) or ( "eczema" ) or ( "eczematous dermatitis" ) or ( "eczematous eruption" ) or ( "eczematous skin" ) or ( "dermatitis,

"dermatologic agents") or (" immunomodulator") or ( " systemic drugs" ) or ( "biologics" ) or (" immunomodulator") or ( "immunospress" ) or ( "immunospressive" ). in the search of cebd coronavirus dermatology resource of nottingham university we focused on the link of skin manifestations of coronavirus and coronavirus and specific patient groups. we finally complete our search up to may/ / . in the first screening articles assigned to the inclusion and exclusion groups and then the titles and abstracts of articles were review by two expert dermatologists and acceptable articles ( ) searched to find their full text and finally articles (including patients) selected to data entry for this systematic review ( , ( ) ( ) ( ) ( ) ( ) ( ) ( ) ( ) . after researching, we have found nine related articles and the information of these articles are prepared as a table. of the patients reviewed in these articles, ten had psoriasis/ psoriatic arthritis and two had immunobullous disease included pemphigus and mucous membrane pemphigoid. their underlying disease was treated with the following drugs:  from patients with psoriasis/psoriatic arthritis, eight patients were treated with biologic agents (guselkumab: three patients, secukinumab: two patients, apremilast: one patient, adalimumab: one patient, ustekinumab: one patient); two patients were on other immunosuppressive/immunomodulators agents include cyclosporine and methotrexate.  one patient with mucous membrane pemphigoid was treated with prednisolone, rituximab, mycophenolate mofetil and high dose ivig  one patient with pemphigus was treated with mycophenolate mofetil this article is protected by copyright. all rights reserved. at the time of the pandemic, many patients were diagnosed with various dermatoses treated with biological agents or immunosuppressive/ immunomodulators ( ) . although, there is still no strong evidence of a higher risk of infection with covid- in these patients, and clinicians emphasizes that the symptoms and management of disease in these patients are similar to those in the general population ( ) . in addition, for many dermatoses, any mental or physical stress, such as infection or anxiety, may exacerbate the disease ( - ) . this study has evaluated nine case reports of patients with chronic dermatologic diseases treated with systemic agents. of the patients reported, the two patients did not show any symptoms despite close contact with people with confirmed cases of covid- ; at the time of quarantine, these patients showed no signs of the disease and their treatment continued as before. of the remaining ten patients, only one required hospitalization in the intensive care unit. five patients were treated with conventional therapies such as hydroxychloroquine, oseltamivir, lopinavir/ritonavir, antibiotics. other patients were treated with supportive/symptomatic therapies. at the time of the covid- , the biologic agents were discontinued except for one case (which was treated with guselkumab) but the patients did not report any severe exacerbation of their underlying dermatologic disease despite treatment discontinuation. there was only one case of severe relapse of psoriasis after covid- , in which the patient was previously treated with cyclosporine and methotrexate. investigation of these articles showed that the severity of covid- in patients with underlying dermatologic disease treated with biological agents was not more than in the general population. the management of these patients was in the form of discontinuation of the biological agents or immunosuppressive/ immunomodulators and the use of routine and conventional treatments. after the symptoms have improved, treatment of the underlying dermatologic disease can be recommenced as before. our knowledge about managing patients with dermatologic disorders (especially chronic disorders under treatment with systemic immunomodulators) who are affected by covid- in the pandemic is really scarce so for better controlling and managing both underlying dermatoses and concurrent corona virus infections, we need to sum up current relevant data that we did in this systematic review so far. we found that the severity of the disease or the need for hospitalization in these patients was not greater than in normal population. the treatment of the disease in confirmed cases with covid- were similar to that of normal population, with the difference that it is better to stop the patient's previous medications until the symptoms improve. in patients who have already been treated with biological drugs, recurrence of underlying dermatologic disease was mild. after the symptoms of the disease have improved, the patient's treatment could be continued as before. covid- : 'co' stands for corona, 'vi' for virus, 'd' for disease, and ' ' for . cebd: centre of evidence based dermatology classification of the

older adults and those with comorbidities have an increased complication risks and higher mortality compared to the general population. despite appropriate precautions to reduce transmission risk, many dermatology faculty, residents, staff, and their families are at increased risk for covid- infection while caring for patients. telemedicine is being well utilized to treat certain routine and less urgent conditions, and dermatologist attendings and residents continue to treat urgent/emergency cases in-person. as stay at home orders expire, delayed surgeries and in-person semi-urgent appointments will be scheduled, with increased patient volume and heightened covid- infection risk. our specialty must establish guidelines to protect those most susceptible to complications and

will cases of psoriasis increase after covid‐ pandemic? date: - - journal: dermatol ther doi: . /dth. sha: doc_id: cord_uid: kgph lr nan psoriasis exacerbated with hydroxychloroquine and oseltamivir treatment in a patient with covid- will be presented. a -year-old woman with no skin lesions was admitted to the pandemic clinic with the diagnosis of covid- . the patient had a history of psoriasis that has been activated occasionally since childhood. the patient was started orally oseltamivir × mg and hydroxychloroquine on × mg on the first day then × mg. on the fourth day of treatment, the patient had an exacerbation of silver-scaled psoriatic plaques spread quickly all over the body separated from the surrounding tissue with sharp borders. this is the first case of exacerbation of psoriasis during covid- infection in a patient receiving oseltamivir versus hydroxychloroquine. the exacerbation of psoriasis in this patient can be explained by several conditions. first, it is well known that hydroxychloroquine is an inhibitor of the epidermal trans-glutaminase, cause to the collection of the epidermal cells. in addition, hydroxychloroquine promotes il- production through p -dependent il- release resulting in keratinocyte growth and differentiation. therefore, hydroxychloroquine treatment, which was started as a high dose on the first day, maybe the main factor that exacerbates psoriasis in this patient. to date, we did not find any , granulocyte-colony stimulating factor, interferon-inducible protein , monocyte chemoattractant protein , macrophage inflammatory protein alpha, and tumor necrosis factor α. the increasing some cytokines in the covid- that are also accused in the etiopathogenesis of psoriasis may suggest that covid- may be a new entity that exacerbates psoriasis vulgaris. as a result, it can be speculated that hydroxychloroquine, a commonly used drug for covid- infection, can lead to a worldwide increase number of psoriasis that is prevalence between % and %. this condition may lead clinicians to new treatments that do not have immunosuppressive properties. characteristics of and important lessons from the coronavirus disease

symptoms from covid - . however, they are still superficially reported and the consequences of identifying cutaneous lesions early on and its progression were not extensively studied. therefore, the disease's cutaneous and histopathological manifestations must be an object of study among specialists to favour the resolution of the clinical picture . to comprehend how covid causes dermatological alterations, affected areas, types of cutaneous manifestations, the period of appearance, cure and histological findings can provide subsidies for the disease's early recognition, to support a more effective clinical management of cutaneous lesions and give assistance in the screening and risk stratification . the study's object is to identify clinical and histopathological findings of cutaneous manifestations of covid patients. the bibliographic research was made in june , using the research strategy (covid or covid or corona or coronavírus or sars-cov- ) and (cutaneous or cutaneous manifestations) in the following databases: pubmed, cinahl, cochrane, web of science and scopus. the publication period was limited to . a total of articles were identified in the search, two reviewers independently analysed abstract and complete texts. seventeen studies that involved cases with covid and skin manifestations were included, most were adults, female and their age varied between to years old (chart ). the lesions were classified, mainly as maculopapular, erythematous, vesicular and urticarial , , , . however, such lesions must be cautiously analysed, because they are common and may have divergent origins. cutaneous polymorphism can be related to different reasons such as differences in the virus and the host . the predominant places were the torso and body's extremities and the latency period of the cutaneous symptoms varied from one to days, in contrast, the lesions' progressive disappearance varied from four days to three weeks. histological analysis and biopsies of the skin suggest the prevalence of spongiosis, perivascular infiltration of lymphocytes and thrombogenic vasculopathy , , . spongiosis can ben related to the immune response to the infection, which leads to the activation of langerhans' cells and vasodilation . the thrombotic vasculopathy occurs due to the deposition of c b- and c d, in addition to their co-location with glycoprotein arising from covid . covid can manifest several skin changes and mostly are maculopapular, erythematous, vesicular and urticarial. these lesions differ from their intensity, appearance period and duration. histopathological findings suggest spongiosis, thrombogenic vasculopathy and perivascular infiltration of lymphocytes. urticarial erup-tion in covid infection complement

doc_id: cord_uid: hfuvm oh we aim to evaluate the change in the diagnostic spectrum in dermatology outpatient applications compared to before covid‐ . all patients were enrolled from the department of dermatology between february and may , , the duration of weeks before covid‐ and eight weeks after were analyzed in parts consisting of weeks. data obtained from the database such as age, gender, diagnoses were anonymized. repeated applications with the same diagnosis in ten days after the first presentation were ignored. compared to the pre‐outbreak, there was a . ‐fold decrease in dermatology applications in the first month after covid‐ and an . ‐fold in the second month. we found a significant increase in the frequency of diagnoses such as generalized pruritus, pityriasis rosea, alopecia areata, bacterial skin/mucosa diseases, and zona zoster after covid‐ . the frequency declined in diseases such as verruca vulgaris, hyperpigmentation, skin tag, melanocytic nevus, seborrheic keratosis/solar lentigo. it has been found that the frequencies of most diseases, including acne (⁓ % of patients), did not change. we think that many factors, such as affecting the quality of life, risk perception, increased stress burden may cause a change in the diagnostic distribution of the dermatology applications. this article is protected by copyright. all rights reserved. pneumonia cases caused by a newly identified coronavirus arose in wuhan, china, on december . the world health organization (who) named the disease as the coronavirus disease (covid- ) on february . covid- , which initiated in china, affected many countries in a short time and spread to the whole world. the first case in turkey was seen on march , , the day who declared a pandemic , . although the disease affects all age groups, it is more common in men . some patients can be defined as a high-risk group for death because it is more severe in the elderly and those with underlying comorbidity. it was reported that of the patients who died, . % were aged - years, . % were aged - years, . % were aged - years . thus, we estimate that the risk perception in the population may differ according to age and gender. after the first confirmed-case, the government took step-by-step a series of radical measures, including curfews, to ensure social isolation due to arising new cases in all cities across the country within a short time. in this context, face-to-face education was stopped in schools and universities and distance education was started. flexible working hours were set at all public institutions, including hospitals. common areas such as shopping malls, hairdressers, barbershops, restaurants, places of worship, cafes, cinema, and theatre were closed indefinitely. domestic and international flights and intercity trips have been stopped. a curfew was imposed over the age of and fewer than as of the last week of march and the first week of april, respectively. in some cities, curfews were imposed on all age groups only on weekends and public holidays. the call "stay at home" to all citizens has been repeated continuously through all media channels. as a result of all these measures, there this article is protected by copyright. all rights reserved. were over identified cases and death of covid- by june , , in turkey per worldometer, a reference website that provides real-time world statistics . the case fatality rate (⁓ . %) in our country is slightly lower than the overall case fatality rate envisaged as % in the article published in lancet on january . during the pandemic, it has been recommended to limit the outpatient services and to develop mechanisms to filter elective applications until the outbreak is controlled . we aim to evaluate the change in the frequency, profile and diagnostic spectrum of the patients who applied to dermatology department, which may occur due to all these regulations, restrictions and covid risk perception varying according to the patient. we ask to have a sense about the motivation reasons pushing to seek medical advice in such a period, to understand our patients better. all patients were enrolled from the department of dermatology and venereology in the regional training and research hospital between february and may , . we evaluated the months within these dates to divide them into four weeks of five consecutive working days, excluding weekends and public holidays. thus, a -month period consisting of weeks before the covid- outbreak and eight weeks after the first confirmed case was achieved. data such as age, gender, application dates, the first three of the icd- (international classification of diseases- th revision) codes entered into the system were obtained from the electronic registration database. these data were anonymized on the condition that individual uniqueness was maintained in applications to outpatient clinics. patients with recurrent presentations for control or follow-up and their diseases were identified. however, this article is protected by copyright. all rights reserved. repeating applications with the same diagnosis in ten days after the first presentation were ignored. the reasons such as the wide diagnostic spectrum, lack of icd- code corresponding to each diagnosis, and the unique style of each doctor at the entrance of icd- codes in the dermatology practice necessitated the standardization of diagnostic data within the framework of certain principles in such a retrospective study. for this purpose, the first three icd- codes entered into the system for each patient were reassessed by each patient's own doctor, based on the classification of the diseases in dermatology textbook edited by bolognia et al. . for the same patient, separate diagnoses related to each other were attempted to be expressed as a single origin diagnosis, free from sub-breakings of the disease classification (e.g. xerosis + dermatitis = xerotic eczema, pruritus ani + lichen simplex chronicus = lichen simplex chronicus, pruritus + atopic dermatitis = atopic dermatitis etc.). patients without an additional dermatological diagnosis other than pruritus were evaluated as the "idiopathic pruritus and dysesthesia". a small number of patients who applied for consultation only and had no significant complaints were included in the title of "undetermined reason for examination and observation". we considered only the first icd- codes for patients with multiple irrelevant diagnoses. thanks to these principles, different icd- codes, including sub-breakings in the raw data, were reduced to main titles and subtitles. then, the application date and the diagnoses of patients with repeated presentations were compared with each other via the program. in this way, according to the previous presentations of the relevant patient, application types could be classified under the names of normal and control/follow-up. this article is protected by copyright. all rights reserved. this single-centre cross-sectional retrospective-study was approved by the ethics committee of regional training and research hospital, erzurum, turkey (decision no: / - ) and ministry of health scientific research platform (application form number: - - t _ _ ). this study was conducted as per the latest version of the "helsinki declaration" and the "guidelines for good clinical practice". no patient consent was required, provided that the data such as name and citizenship numbers were anonymized by the it team and with the permission of the ethics committee. nevertheless, informed consent for the study was obtained from patients who were only interviewed by phone. pearson's chi-squared test was used for categorical variables. in chi-square tests with a degree of freedom greater than , pairwise comparisons (post-hoc) were performed using the z-test. after checking the normality distribution of scale variables by kolmogorov-smirnov test, independent samples were compared with appropriate significance tests (kruskal-wallis h test or mann-whitney u test). results were presented as the median (interquartile range) or count of the patients (percentage). the change in application frequency and age distribution by workdays and weeks was displayed with the "scatter with straight lines" graphic. two-sided p-values of < . were considered statistically significant. correction for alpha inflation (bonferonni style) was applied as post-hoc after the kruskal-wallis h and chi-square tests. it was determined that ( . %) of applications to all clinical departments, except covid- outpatient clinic, were made to dermatology outpatient clinics within weeks ( february- may ). as with the dermatology outpatient clinic, there was a gradually significant decrease in hospital-wide applications (p < . ). also, the proportion of those who visited the dermatology outpatient clinics, among applicants to the hospital was about . % before covid- and then decreased statistically significantly to . % and . %, respectively (p < . ). different patients were evaluated at visits. ( . %) patients with ( . %) applications presented in the last -weeks before covid- . in the first and second months after covid- , ( . %) patients with ( . %) applications and ( . %) patients with ( . %) applications attended to our outpatient clinics; respectively ( table ). the changes in application frequencies, age, and gender distribution before and after covid- summarized in table , figs. , and . it was observed that after the firstconfirmed covid- case, the number of patients examined in the daily outpatient clinics has decreased from to in the first week, to and below in the second week. the patient's median age, following a stable curve before covid- , followed a fluctuating course during the outbreak, and the frequency of female-dominant application turned out to be equal over time. before and after covid- , the diagnostic distribution of patients applied to the dermatology outpatient clinics for three periods consisting of -weeks was as in table . the repeated applications in the three months belonged to patients, and their number of visits ranged from to . respectively, ( . %) and ( . %) of them were diagnosed with acne and verruca vulgaris. others applied to the outpatient clinics more than once with the following diagnoses: various eczematous dermatitis ( , . %), urticaria/angioedema (n= , . %), anogenital warts ( , . %), idiopathic pruritus ( , . %), scabies ( , . %), superficial skin/nail fungal infection ( , . %), atopic dermatitis ( , . %), psoriasis ( , . %), bacterial skin/mucosa diseases ( , . %) and callus ( , . %); respectively. besides, a total of ( . %) patients with different diagnoses consisting of - patients, applied to the outpatient clinic at least two times. the rate of repeated applications was statistically significantly higher during the outbreak compared to before (p< . ). . % of acne patients examined in these three months had repeated application. apart from this, the diagnoses of those who applied to the outpatient clinic more than once during this period were as follows in order of frequency: anogenital warts (n = / , . %), verruca vulgaris ( / , . %), scabies ( / , . %), psoriasis ( / , . %), idiopathic generalized pruritus ( / , . %), urticaria/angioedema ( / , . %), atopic dermatitis ( / , . %), bacterial skin/mucosa diseases ( / , . %), superficial fungal skin/nail infections ( / , . %). after the covid- pandemic, which rapidly affected the whole world, there were significant changes in the application to outpatient clinics due to reasons such as measures, call to "stay at home", and panic in the community. it was understood that the number of patients decreased for the first time in the period when there was news that the refugees from iran quarantined in our city. however, it increased again quite rapidly with the announcement of favorable developments (fig. ) . it is noteworthy that a slight fluctuation occurred in the this article is protected by copyright. all rights reserved. median age of patients who applied to outpatient clinics during this period. we have found a logarithmic decline in the frequency of application to our outpatient clinics within about weeks after the first confirmed case was announced. this shows how effective awarenessraising campaigns are in reducing application to hospitals without any legal restrictions yet. compared to the pre-pandemic, there was a . -fold decrease in applications to dermatology outpatient clinics in the first month after covid- as a transition period, and an . -fold decrease in the second month. in general hospital applications, there was a decrease of . times and then . times, respectively. so, compared to other departments, there was a more obvious loss in applications to dermatology outpatient clinics. while there was female dominance in dermatology before covid- , the gradual equalization of the female to male ratio indicates that the risk perception does not differ in terms of gender. after the first confirmed case, the median age line slipped up, and the curve became more stable with the introduction of a curfew for less than years of age. the slight movements of the curve before curfews and the fluctuating course until the curfew for less than years of age indicate that the risk perception varies by age. however, the young age group exhibits inconsistent behavior in outpatient applications. although the risk of death from covid- is lower in young individuals, they can cause the disease to spread rapidly . considering their inconsistent behavior, we understood that the curfew brought to this age group is crucial. there were significant changes in the distribution of diagnosis for some dermatologic diseases after the outbreak ( table ). considering that the frequency of application to the outpatient clinic captured a stable curve after two weeks, we found it appropriate to consider the first month after covid- as a transition period. when evaluating the change in frequency distributions, we commented on the results between "last -weeks before covid- " and " nd -weeks after covid- " to reveal the difference more clearly. in our study, we found a significant increase in the frequency of diagnoses such as idiopathic generalized pruritus, pityriasis rosea, alopecia areata, bacterial skin/mucosa diseases, and zona zoster/post-zoster neuralgia after covid- . in such an analysis to be made at an ordinary time, the frequency changes will suggest that it is due to the seasonal relationship of the disease and the change in its frequency in the community. in such an extraordinary period, it can be assumed that the causes such as the differentiation of personal risk perception due to age, comorbidity, occupation, etc., increased social stress, and changing personal hygiene habits may alter the diagnostic distribution. various studies have shown that psychological disorders such as anxiety and depression increase in the community during the covid- outbreak , . it is known that diseases such as idiopathic generalized pruritus, alopecia areata and zona zoster/post-zoster neuralgia are associated with stress , . besides, these diseases can significantly affect the quality of life (qol) [ ] [ ] [ ] . therefore, the needs of patients to seek medical advice may be superior to the risk perception of covid- . the increase in bacterial skin/mucosa diseases may be through the shifts from departments such as infectious diseases and internal medicine, which have a primary role in outbreak management. also, it may be secondary to xerosis and eczema, the frequency of which is reported an increase due to changes in personal hygiene behaviors , . the absence of an increase in the frequency of xerotic eczema and contact dermatitis in our study should not be concluded that such complaints do not increase in the community. because, based on many studies and our experience, we think that the frequency of xerosis cutis and contact dermatitis increases in the this article is protected by copyright. all rights reserved. community , . the absence of an increase can be explained by the reasons such as predicting the etiology by patients, not associating with covid- , not being experienced for the first time and easily treating the disease with the use of a moisturizer. the increase in the frequency of pityriasis rosea can be explained by the opposite of the reasons listed for contact dermatitis. because pityriasis rose-like lesions have been reported among the cutaneous findings of covid- , but it may also cause undue anxiety in patients who experience the disease for the first time . another reason is that pityriasis rosea increases in the spring seasons, which coincides with the period after covid- . although a significant increase in the frequency of panniculitis is unusual, statistical analysis could not be performed due to the low number of cases. in % of covid- patients, many skin findings, except panniculitis, such as erythematous rash, petechia, urticaria, vesicular rash, livedo reticularis, and pernio have been reported , . all pityriasis rosea (n= ) and panniculitis (n= ) patients diagnosed after covid- were contacted by phone, and any suspicious condition related to covid- was questioned. however, no patient had an anamnesis associated with covid- it was found that the frequencies of most diseases did not change. acne, which is onequarter of the applications among all diseases, was in this group. various studies have shown that depression, anxiety disorders, and body dysmorphic disorder are higher in acne patients , . also, it was reported that there was a significant effect on the qol, depending on the severity of acne . some diseases (such as psoriasis, urticaria/angioedema and behçet's disease) requiring follow-up can seriously impair patients' qol when they are severe . this article is protected by copyright. all rights reserved. one or more of the following reasons: the risk perception of patients in this group is similar, the treatment plan for chronic diseases is pre-drawn, and some diseases do not cause severe deterioration in their qol. the frequency decline in diseases such as verruca vulgaris, hyperpigmentation, skin tag, melanocytic nevus, seborrheic keratosis/solar lentigo suggested that these diseases do not affect the qol too much or that such diseases can be ignored during the outbreak. it was reported that melasma compared to vitiligo is less associated with depression, anxiety, and somatoform disorders, though it causes more severe impairment of life quality . unlike hyperpigmentation, the constant frequency of hypopigmented skin diseases suggested that the motivation for outpatient applications is different for each disease. acne ( . %), verruca vulgaris ( . %), urticaria/angioedema ( . %) and anogenital warts ( . %) were the primary ones in the distribution of patients with repeated applications within three months. besides, anogenital warts ( . %), verruca vulgaris ( . %), acne ( . %) and scabies ( . %) were at the forefront in the frequency of disease-specific repeated applications. it was understood that the patients who desired treatment (drug or procedure) and experienced treatment failure needed to come to the polyclinic more than once during the pandemic. indeed, the frequency of repeated application was significantly higher in the post-covid- period than before. the study has certain limitations. since the study was retrospective, we had no data such as detailed clinical examinations, life quality, anxiety levels, their treatments, and individual risk perception for covid- . patients often have multiple independent complaints, and sharing their complaints without prioritization may change the order of the this article is protected by copyright. all rights reserved. diagnoses in the database. besides, due to the extreme diversity of dermatological diseases, dermatologists work within a narrow framework for the use of icd- in clinical practice. this study was carried out to understand the reasons why patients with dermatological diseases with low urgency and mortality come to the hospital in such a worldwide fatal pandemic period. many factors such as affecting the qol, risk perception varying according to the individual, increased stress burden, dermatological rashes encountered for the first time caused the change in the diagnostic distribution of the dermatology applications during the pandemic period. however, the motivation for application to dermatology

needs of the patients. chose the patient wisely and cautiously considering the following factors; rapid spread of virus, incubation period of days when the patient is asymptomatic but still transmitting the virus, more than % cases being asymptomatic, low sensitivity of the rapid test being - %, uncertainty about the vaccine and drug for treatment of covid- and upon that the worldwide scarcity of personal protective equipment and masks. the ideal time to start practice would depend on the rules laid down by local or central governing bodies but the most important factor is that the treating physician should be prepared both mentally and administratively and be well informed about the current scenario. the prime thing would be to have a disinfection strategy in place and adequate supply of ppes for protection for self and staff in the clinic. transmission -current information suggests that the two main routes of transmission of the covid- virus are respiratory droplets and contact. vertical transmission has also been reported. respiratory droplets are generated when an infected person coughs or sneezes. any person who is in close contact (within m) with someone who has respiratory symptoms (coughing, sneezing) is at risk of being exposed to potentially infective respiratory droplets. droplets may also land the virucidal efficacy of chemical germicides against coronavirus has been investigated. a study of disinfectants against human coronavirus e found several disinfectants were effective after a -minute contact time; these included sodium hypochlorite (at a free chlorine concentration of , ppm and , ppm), % ethyl alcohol, and povidone-iodine ( % iodine). a study also showed complete inactivation of the sars coronavirus by % ethanol and povidoneiodine

and should be used cautiously. studies have shown that sars corona virus can survive on plastered walls, stainless steel surfaces, plastics and even glass slides from - hours. it is stable in feces and urine for at least - days. , hence, all the surfaces should be disinfected as they can act as potential source of infection before commencing and after finishing the procedures.  waiting time

biologics? date: - - journal: dermatol ther doi: . /dth. sha: doc_id: cord_uid: nq jwgr the new coronavirus pandemic poses question and challenges for dermatologists. one of question is if psoriasis patients treated with immunomodulating and immunosuppressive drugs have to discontinue their treatment in the midst of fears for the infection and its consequences. one of the challenges is how can we support our patients in this critical time. previous coronaviruses outbreaks reports, current published evidences on pathogenesis and on clinical reports of covid infection in immunosuppressed patients are used to make a scientifically based decision. a new coronavirus infection started in china in december and it quickly spread to other countries in and outside asia. in january the world health organization termed this new virus sars-cov- as it is very similar to the one that caused the sars outbreak (sars-covs). the ongoing sars-cov- or covid pandemic is a great concern for public health and italy is one of the countries that has the largest outbreak outside mainland china with increasing number of infected people and deaths. psoriasis is an immune mediated disease that affects almost % of population. it is treated targeting effector cytokines identified as crucial in the pathogenesis of this disease: tnf alpha, il- - , il- and il- . the usual approach to this disease is to suggest continuous treatment for patients since alteration of therapeutic schedule could enhance the risk of immunogenicity and thus treatment failure. recently some concern over the possibility that cytokine directed immunosuppressive treatment may be a risk factor for sars-cov- infection in psoriasis patients has been expressed. the pandemic scenario changes very rapidly with new data on the clinical and serological characteristics of affected cases being reported every day. we think that is time to review more thoroughly the available data in the literature, in order to give a clearer advice to dermatologist. we screened concerning the pathogenesis of sars and mers it seems that a th activation associated with the production of high levels of proinflammatory cytokines may play a pivotal role in the disease. cytokines such as il- , il- and il- , and chemokines such as il- , ccl and cxcl were elevated in sars patients and diminished in patients that recovered, accompanied by a robust anti-virus antibody response. in mers a worst outcome was associated with high levels of il- and cxcl and with high levels of il- and il- . moreover proinflammatory cytokines genes such as il- , il- , tnf, and chemokines such as cxcl and ccl , were found to be overexpressed in sars cov infection by microarray datasets analysis. the importance of the role of massive release of proinflammatory cytokines (cytokine storm) is underlined by the fact that there is a significant difference in the concentration of serum of ifn-γ, il- , il- , il- , and tgfβ and of chemokines such as ccl , cxcl , cxcl , and il- between severe disease sars patients compared to uncomplicated sars patients. lethality in sars was directly correlated with the serum concentration of ifn α and γ and with up regulation of ifn-stimulated genes such as cxcl and ccl . furthermore, patients with severe disease had low levels of anti-inflammatory cytokine il- . both in sars and mers it seems that the severity of the disease depends from viral load in the airways, age and comorbid condition. no comment has been ever made, in literature, on concomitant immunosuppression in these patients. , being older with comorbid conditions such as hypertension, diabetes, obesity, heart and renal failure were associated with more severe cases. , several treatments have been proposed for sars and mers else than clinical support: antiviral, anti-malaria drugs, interferons, immunoglobulins, and vaccines. given the potential role of proinflammatory cytokines in the pathogenesis of sars and mers severe disease, also ant inflammatory drugs have been suggested as novel treatments in these diseases. drug repurposing studies have identified immunosuppressive drug, cyclosporine, as potentially useful. moreover given the role of tnfα in these diseases, this cytokine has been suggested as a putative target in respiratory viral disease in which a partial tnf-α inhibition may benefit patients. recent reports have shown that infection with sars-cov induces the production of il- β, ifn-γ, ip , and mcp- . the concentration of these cytokines (ip , mcp- ) is directly related to the severity of the disease and with the probability of being admitted to the icu. . since there are also reports that sars-cov- may induce also production of th type cytokines further studies are needed to clarify the role of the cytokine storm into this disease. high levels of il- , il- , gm-csf, mip -α, and tnf-α have also been correlated with disease severity in sars-cov- infected patients. among predictors of fatality in retrospective studies from china cases, high il- plasma levels was suggested, implying that mortality might be due to virally driven hyperinflammation. thus, it could be suggested that a cytokine storm is responsible for massive tissue destruction and correlates with disease severity also in sars-cov disease. this aspect has been also suggested for pediatric patients. even in this age group, critically ill patients showed high levels of il- , il- , and ifn α. anedoctical case series and trials with promising results have been reported with drugs with immunomodulating activities: hydroxychloroquine and azithromycin as well as cytokine targeting drugs such as tocilizumab and jak-kinase inhibitors . however currently, effective infection control intervention is the only way to prevent the spread of sars-cov- . what about patients with inflammatory conditions? how should we treat them during covid- pandemic? there is controversy on this argument: question is to carefully balance the higher risk of infection in patients on immunomodulating therapy with the potential beneficial effect of reducing immunity. , as already reported for sars and mers, also patients with sars-cov- infection may present with some characteristics that can predict severity of disease. literature is very consistent in reporting that elderly male patients, with comorbidities were more prone to develop more severe disease. the most frequent comorbidities present in % to % of critically ill patients are: diabetes, cardiovascular disease, pulmonary disease (copd), hypertension and malignancy. , , a very large study of patients from china confirmed that the majority of cases and the higher mortality ( , %) were among elderly people. the same study showed that the fatality rate among those without comorbidities was , % while in those with cardiovascular disease it was , %, and , % in those with diabetes, , % in those with chronic respiratory diseases, % for those with hypertension, and , % for those with cancer. some author wisely acknowledge that patient characteristics may change in different population affected, however an early analysis of the difference between italian and chinese cases concluded that the most at risk patients for severe disease were very similar. more recent italian data confirm that % of deceased patients were years of older and that more than % had three or more comorbidities the most frequent of which were: hypertension, ischemic heart disease and diabetes. the only relevant publication reporting immunosuppression and potentially lethal sars cov- illness was the one regarding the very limited washington state outbreak in which other comorbidities associated with the patients admitted to icu were: history of organ transplant ( , %), immunosuppression ( , %), and rheumatologic disease ( , %). case reports and large patients series, however, mitigate the fear about the potential high risk for immunosuppressed patients. at the best of our knowledge two papers address the issue. , the first is a large case series coming from a city in the epicenter of the outbreak in italy. it describes the cases recorded in a very big pediatric liver transplant population. only three patients tested positive and no patient among over liver transplanted, with autoimmune liver disease and under chemotherapy for liver cancer developed serious illness due to covid- . the second is a case report from wuhan, reportedly one of the cities with the largest number of kidney transplant in china, it describes the case of an adult kidney transplant patient with covid- pneumonia. this patient recovered after immunosuppressive treatment reduction and introduction of intravenous immunoglobulins and low dose steroids. noteworthy is the evidence that also this patient had high plasma levels of il- , il- , and tnf-α and that his disease course was similar to nonimmunosuppressed patients. | conclusion . | should we fear for our psoriasis patients treated with biologicals? during this pandemic we have to base the decision on whether continue or withhold psoriasis treatment on scientific evidences. we must be very careful and act with caution since, as we presented, we only have indirect evidences. in times in which the covid- fear could lead to over psychological distress, people with disease such as psoriasis, may worsen, since they are already striving with a chronic psychologically distressing disease. stopping immunosuppressive or immunomodulating treatment in psoriasis could lead to reduced response at retreatment due to several reasons, the most important of which is immunogenicity. we can speculate on three strong evidences that were discussed above: the evidence that no reports have being published so far on immunosuppression being a risk or worsening condition for covid- disease. the evidence that the severity of the disease, as happened for other coronaviruses outbreaks, is linked to a "cytokine storm "that has to be controlled in order to reach recovery. moreover cytokines targeted by psoriasis treatment (such as tnf-α, il- , il- ) are not among the most relevant in covid related inflammation. the evidence that the most important risk factors leading to more severe illness for covid- sars are comorbidities that we can find also in our psoriatic patients, the more obvious consequence of this evidence is that that we have to stress virus containment measure to these fragile patients. in conclusion we think that with all due caution, the treatment of psoriatic patients with biologicals should not be discontinued during the time of this pandemic. caution has to be focused on elderly patients with coexisting morbidities such as hypertension, diabetes and obesity that enhance their chance of developing, if ever infected, a more severe disease. in this specific group of patients the decision to suspend the treatment should be made when patients develop flu like or covid- specific (anosmia, asthenia) symptoms and if are exposed to high risk contact with infected people. pa and gg conceived and the manuscript, participated in the analysis and

to protect the well‐being of healthcare providers while providing a sufficient workforce to respond to the coronavirus disease (covid‐ ) are vital for pandemic planning. in this article, we will discuss this problem from a dermatological aspect. this article is protected by copyright. all rights reserved. maintain at least metre distance from anyone who is coughing or sneezing, to avoid touching eyes, nose, hair, ear and mouth, and to stay home if one feels unwell. the best way to protect everybody against covid- is done by frequently cleaning the hands. by doing this ; we eliminate the viruses that may be on our hands and avoid infection that could occur by then touching our eyes, mouth, and nose. some antiseptics such as alcohol or chlorine can try to kill the viruses that have already entered our body. but these substances can be harmful to clothes or mucosal surfaces including eyes and mouth. soap works better than alcohol and disinfectants at destroying the structure of viruses. soap dissolves the fat membrane, and the virus falls apart like a house of cards and "dies," or rather, it becomes inactive as viruses aren't really alive. viruses can be active outside the body for hours, even days. disinfectants, or liquids, wipes, gels and creams containing alcohol have a similar effect but are not as good as regular soap. apart from alcohol and soap, antibacterial agents in those products don't affect the virus structure much. consequently, many antibacterial products are just an expensive version of soap for virus killing. soap is the best, but alcohol wipes are good when soap is not practical or handy, for example in office reception areas. soap contains fat-like substances known as amphiphiles, structurally similar to the lipids in the virus membrane. the soap molecules "compete" with the lipids in the virus membrane. that is more or less how soap also removes the normal dirt of the skin. the soap molecules also compete with a lot of other non-covalent bonds that help the proteins, rna and the lipids to stick together. the soap is effectively "dissolving" the glue that holds the virus together. when you add to that all the water it is even better. the soap also outcompetes the interactions between the virus and the skin surface. soon the virus gets detached and falls apart like a house of cards due to the combined action of the soap and the water (ying-hui jin et al ). alcohol-based products include all "disinfectants" and "antibacterial" products that contain a high share of alcohol solution, typically %- % ethanol, sometimes with a bit of isopropanol, water and a bit of soap. ethanol and other types of alcohol do not only readily form hydrogen bonds with the virus material but, as a solvent, are more lipophilic than water. hence, alcohol does dissolve the lipid membrane and disrupt other supramolecular interactions of the virus. however, you need a fairly high concentration (may be %-plus) of the alcohol to get a rapid dissolution of the virus. to sum up, viruses are almost like greasenanoparticles. they can stay active for many hours on surfaces and then get picked up by touch. then they get to our face and infect us because most of us touch our face frequently. water is not effective alone in washing the virus off our hands. alcohol-based products work better. but nothing beats soapthe virus detaches from the skin and falls apart readily in soapy water. supramolecular chemistry and nanoscience tell us not only a lot about how the virus self-assembles into a functional, active menace, but also how we can beat viruses with something as simple as soap (chloé , varbanov, raphaël , ). alcohol-based antiseptics are better tolerated and lesser irritant than soaps (williams ). however, it was observed that washing hands with soap is better than using alcohol-based disinfectants in removing the noroviruses, rhinovirus and h n influenza virus from hands (tuladhar , kopra , grayson ). acidic syndets are lesser irritant than standart soap and we can propose syndet uses during covid- war (korting ). according to the literature knowledge, we can see erythematous rash, petechia, urticaria and vesicles during covid- infection as %. . this finding can indicate that covid- may not be a lung disease but rather a red blood cell-targeting disease. this finding can also clarify these vascular changes of skin during covid- infection. in our opinion, we will also see erythroderma, erythema nodosum, erythema multiforme, pruritus and different rashes associated with covid- in the future. also we have a risk of covid- vaccine-related skin eruptions in the future years like other viral vaccine-related eruptions such as urticaria, scleroderma, maculapapular rashes (recalcati, ) . if our patients have atypical skin rash accociated with fever, cough and shortness of breath; we must think covid- associated skin rash as the diferential diagnosis. during this covid- pandemia, we can see skin problems associated with the personal protective equipments in health-care workers. medical masks can induce acne vulgaris, rocasea, irritation, ecchymosis, even erosions. we can recommend topical benzoiyl peroxide, retinoic acid, antibiotics for acne vulgaris; topical metronidasole and azeleic acid for rosacea, barrier creams to prevent facial irritation and also frequent changing of the mask. medical gloves can cause maceration and contact dermatitis reponding well to topical steroids and moisturizer creams. we can recommend regularly changing of the gloves especially of latex-free type. frequent washing of the hands with soap and also using antiseptics may induce allergic and irritant contact dermatitis. we can advise moisturizer and barrier creams after cleaning and also bar soaps with moisturizers. ( after covid pandemia, we postponed all non-urgent dermatological procedures such as biopsy, electrocauterisation, cryotherapy, patch and prick tests, dermoscopy, all aesthetic dermatology interventions in mersin university like in all other dermatology departments. we discharged all hospital inpatients who are medically fit to leave and in these days we have only inpatients in our department. we also minimised all non-essential outpatient appointments and we accept only serious and emergent cases now. we are trying to use telemedicine, whatsup, e mail or phone for simple skin issues in our city. there is a very limited evidence base to formulate a specific advice for dermatology patients on immunomodulators with regards to covid- . the following is based on expert opinion, taking into account the known risks of other rna viruses. there are complex interactions between coronaviruse's replication and host immune response in covid- . since there are limited studies, we need more information on the the risk of immunosupression in patients exposed to this virus (beth et al, ). we can propose that mono-immunosupressive therapy, target therapies, immunomodulatory agents such as intravenous immunoglobulin, acitretin etc. in the presence of significant comorbidies including diabetes mellitus, hypertension, obesity . we should do a patient-by-patient evaluation about ongoing treatments in patients with psoriasis, lupus erythematosus, lichen planus etc. in our university, standart medicine student education was cancelled due to covid- outbreak. all universities created e-learning programme such as webinar, online lectures with powerpoint slides and also online conversations. after march , all national and international congress, symposiums and training events have been cancelled or postponed due to covid- pandemia. we barely accomplished our international indercos congress in - march and more than international and national lecturers couldn' t come because of covid- including our hononary congress president prof lotti. we use hydroxychloroquine for the treatment of discoid lupus erythematosus and understand its relative safety. hydroxychloroquine and chloroquine have antiviral activity against covid- in vitro and in small uncontrolled clinical studies with limited and inconclusive results. in covid- , a small non-randomized study from france indicated some benefits with serious methodological flaws, and a follow-up study still lacked a control group. however, another very small, randomized study from china in patients with mild to moderate covid- found no difference in recovery rates. sadly, reports of adverse events have increased, with several countries reporting side-effects including ventricular arrhythmias, qt prolongation, other cardiac toxicities, ocular toxicity and even death. we should know that these drugs may pose particular risk to critically ill persons. due to the remarkable pharmacokinetics and efficacy, azithromycin with immunomodulatory and anti-inflammatory properties, is well established as a potent treatment for some skin diseases such as rosacea, psoriasis and synovitis, acne, pustulosis, hyperostosis, osteitis (sapho) syndrome. combining hydroxychloroquine with the antibiotic azithromycin has also been associated with positive patient outcomes according to low-powered france study (gautret et al, ) . whether this results in better clinical outcomes --ie. if patients recover more quickly --is still being debated. colchicine has been used to treat various dermatologic diseases, some of which are quite seldom, which include behçet's disease, epidermolysis bullosa acquisita, recurrent oral aphthosis, cutaneous vasculitis, chronic urticaria and sweet syndrome fot its anti-neutrophilic immunomodulatory effect. in the last clinical trial called colcorona (colchicine covid- trial), colchicine is being used to reduce the inflammatory reaction caused by covid- that can lead to pulmonary involvement, organ failure and death. it will be used for its anti inflammatory and anti-cytokine storm effects when treating covid- (cynthia et al, ). a variety of repurposed drugs and investigational drugs have been identified for covid treatment. however, evaluation of investigational agents requires adequately powered, randomized, controlled trials with realistic eligibility criteria and appropriate stratification of the patients. these are globally uncertain and testing times. we can prefer webinar and online education models, online examinations, and online patient examination until the covid- pandemic is over. but the most important thing is that we have to work together as a professional community to support one another, therefore upcoming challenges will undoubtedly create learning experiences for us all. literature knowledge suggests that humans have been afflicted by viruses throughout their evolutionary history, although the number and the types have changed. endogenous retroviral insertions since the divergence between humans and chimpanzees were capable of directly affecting hominid evolution through changes in gene expression and development. it is estimated that there are about viruses on earth and most of the viruses are bacteriophages, and most of them are in the oceans. the human genome project has revealed the presence of numerous viral dna sequences scattered throughout the human genome. these sequences make up around eight per cent of human dna, and appear to be the remains of ancient retrovirus infections of human ancestors. these pieces of dna have firmly established themselves in human dna. most of this dna is no longer functional, but some of these friendly viruses have brought with them novel genes that are important in human development ( pattern of early human-to-human transmission of wuhan a rapid advice guideline for the diagnosis and treatment of novel coronavirus ( -ncov)

for dermatologic surgeries amid the covid‐ crisis date: - - journal: dermatol ther doi: . /dth. sha: doc_id: cord_uid: sb rmm nan to the editor: the coronavirus disease (covid- ), caused by severe acute respiratory syndrome coronavirus (sars-cov- ), has significantly affected clinical practices. currently, elective dermatologic procedures (ablative laser procedure, laser hair removal) are deferred, with only emergency dermatological surgeries being performed to lessen viral spread and preserve personal protective equipment (ppe). as covid- prevalence decreases, postponed procedures will be scheduled. for mohs micrographic surgery (mms) and excisions, hemostasis is often achieved by electrosurgery, generating surgical smoke plume. although data on transmission of sars-cov- via surgical smoke is unavailable, human immunodeficiency virus, hepatitis b virus, and human papillomavirus have been detected in surgical smoke . since sars-cov- may be transmitted through aerosols , it is critical to reexamine recommended protective measures for dermatologic surgery. the use of fitted respirator or surgical masks and smoke evacuators was recommended to minimize the infectious, inhalation, chemical and mutagenic risks of surgical smoke prior to covid- . for smoke evacuators, minimal flow rate, determined by internal diameter and suction strength, nozzle positioning, filtration efficiency, and regular maintenance impact efficacy . since covid- is transmitted through droplets and aerosols , it is premature to resume elective laser procedures, including ablative co and hair removal. however, deferred nonelective excisions and mms for skin cancer will need to be performed in the near future. the centers for disease control and prevention (cdc) recommends n respirator use for healthcare workers participating in aerosol-generating procedures (agp) . therefore, n respirators are essential for dermatologic surgeons and staff operating on mucosal regions and/or generating aerosols with electrocautery (table i) . the cdc recommends against extended use this article is protected by copyright. all rights reserved. or reuse of respirators following agp . however, given n shortages, particularly in outpatient dermatology practices, following this recommendation may be unrealistic, with extended use unavoidable. a surgical mask covering the n respirator may be considered to extend longevity. decontamination of n s for reuse or d-printed masks have also been proposed; testing would be required to ensure effective filtration . in an intubation simulation , secretions were recovered from exposed skin (i.e. neck and ears) and hair of healthcare providers following two coughing episodes despite use of n respirators, eye protection, gowns, and gloves, suggesting that use of standard ppe is likely insufficient. this study raises concern for a similar inoculation pattern from surgical smoke potentially laden with sars-cov- in the dermatologic surgeon's exposed skin and hair, suggesting that a hood covering hair, ears and neck should be utilized. in addition, this infectious material may be transferred to the eyes, nose, or mouth via self-inoculation, a process that can be prevented with proper hand hygiene. finally, to minimize smoke production, electrosurgery units should be set to the lowest effective settings for achieving hemostasis. recommendations for ppe, smoke evacuation, and hand hygiene are shown in table . many hospitals are adequately supporting redeployed resident and attending dermatologists caring for covid- inpatients. as we are discharged from redeployments and perform increasing numbers of essential outpatient dermatological surgeries, it is incumbent upon hospitals, as well as, state and federal governments to ensure adequate access to ppe for all dermatologists and staff. this article is protected by copyright. all rights reserved. this article is protected by copyright. all rights reserved.

is when biologics with long half-lives should be restarted. in our case, the patient recovered from covid- before his next scheduled risankizumab dose. however, more data needs to be obtained about biologics in covid- patients, in particular whether or not biologic dosage timeline should be adjusted based on resolution of infection. a database to collect information on covid- patients on biologic therapy and their outcomes would be instrumental to guide clinicians on best practices for now and in future pandemics. in conclusion, this case illustrates that il- inhibition via biologic therapy in covid- may not correlate with severe respiratory disease. however, the decision to continue biologic treatment should be a shared process between physician and patient on a case-by-case

since ancient times for its medicinal properties. substances collected from various plants are mixed with the β-glycosidase enzyme of the honey bee saliva, digested, and added to beeswax to form the final product. propolis has an important role in hive construction as a waterproof resin; however it also acts as a barrier to yeasts and molds, bacteria, and viruses. propolis is a highly complex mixture, containing over chemical moieties, a number of which have documented beneficial health outcomes. the main constituents of propolis include resins, waxes, essential oils, and pollen, as well as various organic compounds, among which are phenolic compounds, flavonoids, terpenes, esters, aromatic aldehydes and alcohols, and several specific antioxidant compounds including beta-carotene, caffeic acid and kaempferol. a new compound isolated from brazilian green propolis, , -diprenyl- -hydroxycinnamic acid (artepillin c), may be a key immunomodulatory compound. the biochemical composition of propolis is highly variable, and this variety is significantly affected by the geographical origin, climate, water availability and other environmental factors. it is widely recognized, for example, that propolis from temperate climatic zones are rich in flavonoids, phenolic acids and their esters, while propolis from tropical regions are rich in prenylated benzophenones, diterpenes and flavonoids. , that being said, all types of propolis possess antimicrobial, anti-neoplastic, anti-inflammatory, antioxidant, hepatoprotective, cariostatic, and immunostimulatory activity. the natural variety of propolis has traditionally been an obstacle in research and a standardizing medical use. it also cannot be used as raw material (figure ) , and it must be purified by extraction with solvents. be it alcoholic or aqueous, propolis extracts from temperate climate have been shown to possess a potent and broad-spectrum antiviral activity against a diverse panel of viruses such as hsv- , a promising pharmacological approach for treatment of covid- is targeting the downstream effectors, such as p -activated kinases (paks). caffeic acid phenethyl ester (cape), one of the most important constituents of propolis, has shown the property to down-regulate rac (a signaling protein found in human cells), therefore acting as a rac/cdc -activated kinase (pak ) blocker. these data support the idea that cape can be useful as an agent to stop or inhibit coronavirus-induced fibrosis in the lungs. although propolis belongs to the safest natural remedies, on rare occasions, adverse effects of propolis or its constituents are to be expected, especially allergic reactions. therefore, when used in prevention or treatment of covid- , hypersensitivity reactions should be taken into account. viruses causing respiratory diseases invade their host via the nasopharyngeal, oropharyngeal or tracheal mucosa. at present, there are no specific antiviral drugs or vaccines against sars-cov infection for potential therapy of humans. identifying methods able to reduce or prevent colonization, viral adhesion and promote virus shedding on mucous membranes or have the ability to inactivate pathogens and thus reduce virus dose and/or increase immune response would be essential in the management of covid- outbreak. therefore, we suggest that propolis (or its constituents) may represent a low-cost treatment option that may act as potential inhibitors of sars-cov- in the oropharyngeal niche. propolis should be explored as a prophylaxis in high-risk groups, such as individuals in close contact with infected patients. further studies should be conducted for the validation of these compounds using in vitro and in vivo models. these studies must thoroughly characterize the biological activities and underlying mechanisms of action and isolating the most beneficial compounds, mainly those related to antiviral properties. composition and functional properties of propolis (bee glue):

eab i f nan up to now the precise mode of transmission of sars-cov- (severe acute respiratory syndrome-coronavirus- ) has still not been completely described, however the main route is through humanto-human transmission via droplets . multiple studies have concluded that asymptomatic carriers can spread the virus unknowingly , thus leading governments to implement very restrictive rules of social distancing, also recommending the avoidance of multiple sexual intercourses. the knowledge of all possible modes of transmission of sars-cov- infection is the key to improving both the identification of the asymptomatic population and the necessary isolation measures in order to further flatten the curve. we operate in a free service for the prevention and treatment of sexually transmitted diseases (stds), and owing to the lack of publications concerning this specific population, we are speculating that a certain percentage of the asymptomatic population could be spreading sars-cov- through sexual contact (vaginal, anogenital and orogenital). the presence of sars-cov- rna in the feces of covid- patients ( . %) has already been demonstrated in recent studies in wuhan, without being statistically related to gastrointestinal symptoms and/or disease severity. furthermore, . % of these patients showed a persistent positivity for rna search by polymerase chain reaction (pcr) in the stool following viral clearance (negative nasopharyngeal and oropharyngeal swabs) . from a molecular point of view, the ace (angiotensin-converting enzyme ) receptor, largely expressed along the gastrointestinal mucous membranes, has been demonstrated as the cell entry for sars-cov , . the human testis has also been indicated as a potential target of sars-cov- , due to the expression of ace receptor in the leydig cells and cells of the seminiferous tubules, leading to potential defects in spermatogenesis . in addition, some authors suggest that the human testis could provide another potential route of infection. moreover, the positivity for sars-cov- on vaginal swab raises the possibility of both sexual and mother-to-child transmission , although further studies are needed on these issues since no definitive proofs have been found. over the past weeks we have observed cases of confirmed sars-cov- infection in our msm population. this additional data seems to support our speculation, however rectal swabs for the execution of sars-cov- pcr are not still available in our stds clinic. in conclusion, it would be useful to confirm the possibility of other alternative ways of viral transmission. if these speculations are confirmed, we should consider implementing an anal swab in all covid- patients, also in those with negative pharyngeal swab. a further step would be adding sars-cov- serology, pharyngeal, anal and vaginal swabs to our usual std screening also in the asymptomatic population, in order to identify positive cases and to confirm the sars-cov- orogenital route of transmission. covid- outbreak: an overview evidence for gastrointestinal infection of sars-cov- scrna-seq profiling of human testes reveals the presence of the ace

implemented for post covid- resumption of dermatologic surgery services. whilst we commend the authors for their work and comprehensive actions put in place, there was an omission of a critical factor highly pertinent to dermatologic surgery and potential covid- transmission, namely surgical plume. whilst ablative lasers are not ubiquitous in dermatologic surgery departments, the use of cautery forms an integral part of the discipline. numerous studies have shown the hazards of surgical smoke containing toxic gases and metabolites harmful to both the operating dermatosurgeon as well as the patient, in addition to acting as a vector for infectious particles , . covid- has exposed new occupational hazards given the highly contagious nature of the virus through aerosolised procedures. the use of surgical masks may offer partial protection to respiratory droplets; however fine aerosolised particles from surgical plume may continue to pose an infectious risk to patient and staff. the use of specialised masks able to filter particles smaller than microns (the threshold size for surgical masks) such as laser-specific masks or n masks offer better protection to aerosolised particles , .

concentrations of small aerosolised particles, than monopolar cautery when operating with lower power settings. additionally, measures to safely extract generated plume are required such as the use of appropriate plume extractor. air filtration in the surgical theatre should ideally constitute of air-conditioned medical high-efficiency particulate air or ultra-low particulate filter in addition to the above named measures , . given that many dermatologic surgical procedures involve the head and neck area, careful attention to hazards posed by surgical plume and ablative lasers and attempts to

a major role in covid- diagnosis and prognosis. eosinopenia has been associated in up to % of cases and was proposed as possible diagnostic marker for the disease. persistent eosinopenia was associated to higher mortality. on the other hand, an increase of eosinophils in blood was related to an improvement of the overall condition of the patient. furthermore, patients with pre-existing atopic disease (asthma, rhinitis, and atopic dermatitis) seem to be less affected by covid- . therefore, eosinophilia was associated with a protective effect toward the development of covid- . histopathology of some skin rashes arising during covid- shows a perivascular and dermal infiltrate rich in eosinophilic cells. various theories have been proposed in order to explain these findings. eosinopenia may be secondary to cell depletion due to the viral infection or to stress-induced glucocorticoid secretion. eosinophilia might be beneficial thanks to its antiviral effect, as demonstrated for influenza and parainfluenza virus. we can speculate that the non-drug related em and u might be associated to systemic eosinophilia secondary to a strong response to covid- , and therefore possibly to a better outcome of the disease. indeed, nondrug-induced em has been mostly reported in young healthy nonhospitalized covid- patients. u not related to drug reaction was reported

mainly occurs in elderly patients that usually present other comorbidities such as cardiovascular and respiratory problems. this bullous disorder is characterized by an alteration of t-cell immune response, leading to the production of pathogenetic autoantibodies directed against different proteins of the desmosome, and by the release of pro-inflammatory cytokines. this immune alteration clinically manifests with vescicles and erosions on the epithelium of the mucous membrane and of the skin, exposing patients to a higher risk of comorbidities and secondary infections . sars-cov infection has now spread all over the world and higher mortality rates have been reported among elderly and comorbid (diabetes, cardiovascular disease, immunosuppression) patients. in this scenario, patients with bullous pemphigoid are part of the high-risk population and preventive measures in order to minimize the risk of infection must be implemented. we want to share our experience about the management of patients with bullous disorders, in particular pemphigoid disease in our outpatient clinic during covid- pandemic. since the beginning of march , in our dermatological clinic, outpatient visits have been suspended with the postposition of all non-urgent visits, except for oncological dermatology and emergencies. patients ( women and men) with a median age of . years, affected by

healthcare workers is crucial during coronavirus disease (covid‐ ) pandemic and facemask wearing is considered an effective measure to prevent severe acute respiratory syndrome coronavirus (sars‐cov‐ ) infection. however, long‐time use of a facemask can cause pressure sores on the ears and nose bridge and increase the risk of infection. the topical recombinant human acidic fibroblast growth factor (rh‐afgf) was used to cure pressure sores for healthcare workers at zhongfaxincheng campus of tongji hospital. the results from a small sample size survey conducted in zhongfaxincheng campuses of tongji hospital showed that treatment with topical rh‐afgf could significantly inhibit the progression of pressure sores and accelerate the wound healing with no apparent ill‐effects. therefore, we propose that topical rh‐afgf is an effective therapeutic agent for facemask wearing‐induced pressure sores and worth of popularizing and applying. this article is protected by copyright. all rights reserved. coronavirus disease (covid- ), caused by severe acute respiratory syndrome coronavirus (sars-cov- ), is now overwhelming spreading in the world, and been declared a pandemic by the world health organization. among the infection prevention measures for healthcare workers, facemask (the n health care particulate respirator and surgical mask) wearing is considered as an effective measure to prevent sars-cov- transmission. however, long-time use of a facemask with earloop-style can result in pressure sores on the ears' skin. moreover, pressure sores on nose bridge is also liable to occur while working for long time since the metal strip always needs to be extruded to cling the to nose bridge to reach a good respiratory protection. these pressure sores could cause intense discomfort, sick leave, even permanent scarring and high risk of infection for users, which would bring adverse impact on the medical service system. to solve this thorny problem, topical recombinant human acidic fibroblast growth factor (rh-afgf) was provided to healthcare workers to help curing pressure sores at zhongfaxincheng campus of tongji hospital in wuhan, china. zhongfaxincheng campus of tongji hospital is a designated hospital for severe covid- and nearly covid- patients were admitted. there are more than healthcare workers have participated in the fight against covid- , and sizeable numbers of them had suffered pressure sores at varying degrees caused by facemask wearing. once the pressure sores occur, continuing to wear facemasks daily or every other day without any intervention will make the condition from bad to worse. however, our results from a small sample size survey conducted in the healthcare workers in zhongfaxincheng campus of tongji hospital who have used the topical rh-afgf with a concentration of u/ml to cure the stage i/ii facemask wearing-induced pressure sores which were less than cm in size show that treatment with topical rh-afgf could significantly inhibit the progression of pressure sore and accelerate the wound healing. the pressure sores healed within days in all these respondents after treated with rh-afgf consecutively, although masks were still wearing every day or other day along with the treatment. topical rh-afgf is indicated to promote wound healing, including burn wounds and chronic wounds. in the early wound, macrophages and endothelial cells at damaged parts released acidic fibroblast growth factor (afgf) to stimulate proliferation of fibroblasts and keratinocytes, and then enhance local generation of tissue collagen, protease, and various cytokine which appear to be involved in the mechanisms underlying wound healing. , actually, numbers of studies have showed that afgf could improve wound healing in various animal models and clinical trials. , therefore, based on the established role of afgf, it is not unexpected that rh-afgf has a good effect on pressure sores induced by facemask wearing. considering that rh-afgf can increase the expression of collagen and muscle fibers, resulting in enhanced tissue remodeling, a worry that whether excessive tissue repair after long-term repeated rh-afgf application would result in scar formation was raised. however, there was a research demonstrated that the high-dose, repeated rh-afgf application did not cause excessive repair of the tissue or scarring. moreover, the research also demonstrated that no obvious toxicity to the target organs and tissues was observed during the repeated treatment of rh-afgf. these results were consistent with our survey feedback that no healthcare workers have claimed any discomfort or scarring happened during the use of rh-afgf. therefore, we propose that topical rh-afgf is an effective therapeutic agent for facemask wearing-induced pressure sores and worth of popularizing and applying. wounds should be cleaned with chlorhexidine acetate immediately before rh-afgf sprayed. the dosage and frequency of rh-afgf is recommended as u/cm twice daily based on the labeling document and our experience. and if necessary, especially for these nasal pressure sores, cover the wounds with a benzalkonium chloride patch or sterile dressings after the treatment. moreover, besides afgf, the fibroblast growth factor family also comprises basic fibroblast growth factor (bfgf). it was reported bfgf has a role in accelerating skin wound healing and reducing scar formation. thus, topical bfgf may be also a promising choice for pressure sores caused by facemask wearing. however, there are also some points that should be noted. alcohol, iodine, and hydrogen peroxide which are commonly used during the covid- epidemic to kill sars-cov- can affect the activity of rh-afgf. therefore, contact with these substances should be avoided when using rh-afgf. in addition, proper storage temperature for rh-afgf is ~ ℃, don't exposure the product to a high temperature or froze it. it should be mentioned, though, that the rh-afgf use is only an expedient measure, improving protective equipment would be meaningful and benefit global health. and measures including wearing facemask with a plastic handle and pasting benzalkonium chloride patch to the nose bridge before wearing mask were proposed as may have a role in preventing facemask wearing-induced pressure sores. , policies on the use of

first emerged in wuhan, china, rapidly spread all over the world. up to now, the number of confirmed cases has reached over million. dermatologists have contributed a lot to covid- , such as cutaneous manifestations of covid- , teledermatology, and management on patients with inflammatory skin diseases. , here, we systematically reviewed what dermatologists contributed to covid- research. the literature search was conducted on pubmed database on may , . the searching strategy was (covid* or coronavirus*) and (dermatol* or skin* or cutaneous*), and language was restricted to english. the inclusion criteria were ( ) articles published in dermatologic journals based on incites journal citation reports accepted article or ( ) articles published in journals of other categories with the first author from the department of dermatology. articles were identified in pubmed. after independent selection by two authors, articles were included in the systematic review. articles focused on cutaneous manifestations of covid- (n= ), followed by the management on patients with common skin diseases (n= ), operating experience against covid- (n= ), mechanisms and treatment of covid- (n= ), disinfection and personal protective equipment(ppe)-related skin diseases (n= ) and other topics(n= ). the detailed classification was shown in table . articles were comments, were case reports or case-series, were reviews and only was case-control study . the included studies were published in different journals. journals had more than three articles, all of which were dermatologic journals. articles were published in journal of the american academy of dermatology, followed by spain, and from other countries. the current pandemic of covid- aroused great public concern. the number of publications had rapid growth over time, as the plague of covid- spread rapidly all over the world, and dermatologists contributed some precious experience to the community, especially those from the frontline in the "red-zone" area. cutaneous manifestations of covid- has gained much attention. it has been pointed out that a common pattern of cutaneous symptoms may facilitate early diagnosis of covid- . although the cutaneous signs were highly variable and heterogeneous, a recent study reviewed the literature to summarize common features , including vascular complications, maculopapular eruptions, urticarial rash, vesicular eruption, petechiae/ purpuric eruptions, erythema multiforme-like rash, palmar erythema, perifollicular eruption, pruritus, mucosal lesions, and androgenetic alopecia. a systematic investigation is warranted as most studies were derived from case reports and case series under the heavy burden of the pandemic. of note, these articles supported the important role of dermatologists working side by side with their staff from other departments. severe cutaneous manifestations suggested poor prognosis for patients and were beneficial for risk stratification at the early stage of the disease . the management of patients with common skin diseases also attracted much attention, such as psoriasis, skin cancer, pemphigus and atopic dermatitis. long-term this article is protected by copyright. all rights reserved. use of immunosuppressants or biologics was common in these patients. given that these drugs were critical in the treatment and may stimulate the progress of covid- as well, it is a dilemma to make a decision. studies in march, early april were comments based on expert opinions , and studies of case-series in may provided additional evidence to guide the usage of these drugs . the dermatologists are recommended to read these publications to weigh and judge the risks and benefits, for discontinued usage of biologics may decrease the infection risk of covid- and lead to the aggravation of primary diseases at the same time , . dermatologists also focused on measures on quarantine, triage, and resumption, and tricks of wearing masks, and performing dermoscopy. many studies also focused on the personal protective equipment (ppe) and the need for disinfection of public places. a long time of wearing masks or other ppes had reached consensus in causing related skin diseases like dermatitis, and the medical workers should be educated to use them properly to avoid damage. these articles also included the operating experience of dermatology clinics or hospitals, such as the area of telemedicine and emergency management. procedural dermatology was significantly influenced in the pandemic, including surgical and cosmetic techniques, laser, and the photodynamic therapy . the experience facilitates the resume of outpatient dermatologic surgery with efficiency and safety . there still exist some topics having little to do with dermatology were also discussed in dermatologic journals, such as mechanisms and treatment of covid- , covid- and racial disparities , covid- and economy . most articles were comments, personal perspectives with low level of evidence. due to the epidemiologic feature of covid- , cohort study, case-control study, and randomized controlled trial were difficult to conduct to further reveal cutaneous manifestations of covid- and disinfection and personal protective equipment-related skin diseases. studies with larger population are warranted to further evaluate the current findings. national or international studies are also needed for further research. a growing trend was observed in the number of articles, which means covid- has been increasingly attracting the attention of dermatologists. most articles were from epidemic countries, and as the pandemic was declared, dermatologists should have more understanding of covid- , and its relation with dermatology. we would like to suggest our advice as a healthcare worker in the "red-zone" area. services of the dermatology outpatient department and surgery were postponed except for emergency treatment. at the same time, we prioritize the use of telemedicine consultation, particularly for patients receiving biologics treatment. to minimize the risk of exposure, we also conveyed medical knowledge about usage of ppe, skincare, household cleaning, and the coronavirus to protect the dermatological patients. this study systematically reviewed contributions of dermatologists to covid- research. research topics, journals, publication time, and country of origin were accepted article identified, and the value of these articles and their influence on the clinical practice were discussed in detail. we hope this study may help dermatologists to have a better understanding of the mechanisms, management, and the cutaneous manifestations of covid- , the operating experience of dermatology clinics in the " red-zone" area, and to use disinfectant and personal protective equipment properly. how dermatologists can learn and contribute at the leading edge of the covid- global pandemic challenges of

(filtering facepiece)) ( . %), half-face elastomeric respirators ( . %) and full-face respirators ( . %). females significantly more frequently (p = . ) used cloth masks; respirators, half-face

mask as the most frequently used, . % responders declared surgical mask as a dominant type and the remaining . % preferred respirators. most frequently, face masks were worn, independent of the sex of responders, for less than hour per day; however, almost % of users wore them for more than hours per day (table , figure ). concerning all the masks used, single-use masks constituted . %. it appeared that . % of responders who used single-use staff wore it again. there was no difference in this attitude between males and females (table ) . . % of participants declared mask decontamination (table ). this procedure was significantly more common among females (p = . ). washing combined with ironing was the most common modality applied ( %), followed by the use of disinfectants ( . %), ironing alone ( . %) and putting into the oven ( . %). other procedures, such as washing alone, microwaving, boiling and scalding with boiling water, were practiced by a single responder. in this survey, we documented that people with self-reported atopic predisposition wore face masks more frequently. it seems to be obvious as atopic disorders are clearly linked to the involvement of respiratory tract and increased risk of infections. , such relationship could be bidirectional with atopy predisposing to viral infections and viral infection may trigger the atopic asthma. in the previous viral pandemics, there was a clear crisis in the availability of professional face protection. therefore, cloth masks were used commonly. this is in agreement with our findings showing the popularity of cloth mask protection used by the general public. one can consider that despite of protection provided by face masks they may be the cause of some side effects, including breathing difficulties, slurred speech, warming/ sweating and itching. [ ] [ ] [ ] this may influence the use of face masks when they are only recommended and not obligatory. limited availability of professional face masks most probably was the reason that almost one-quarter of our responders used single-use masks several times. moreover, three-quarters of the evaluated individuals wearing face masks declared mask decontamination. nonetheless, our results showed that some practices among young people could be regarded as inappropriate. this can lead to decreased efficacy of face protection and eventual spread of viral infection. therefore, we believe that our results might be of value in construction of general public education campaigns on the proper use of face masks, especially if the role of face mask wearing in controlling the spread of infection is clearly documented. rational use of face masks in the covid- pandemic australian government releases face masks to protect against coronavirus mask crisis during the covid- outbreak covid- : should the public wear face masks? nonpharmaceutical measures for pandemic influenza in nonhealthcare settings-personal protective and environmental measures association between atopic dermatitis and serious cutaneous, multiorgan and systemic infections in us adults risks for infection in patients with asthma (or other atopic conditions): is asthma more than a chronic airway disease? role of viruses in asthma inconveniences due to the use of face masks during the covid- pandemic: a survey study of young people face mask-induced itch: a self-questionnaire study of , responders during the covid- pandemic skin reactions of n masks and medial masks among health-care personnel: a self-report questionnaire survey in china key: cord- -v y nyt authors: singh, parmvir; schwartz, robert a. title: disseminated intravascular coagulation: a devastating systemic disorder of special concern with covid‐ date: - - journal: dermatol ther doi: . /dth. sha: doc_id: cord_uid: v y nyt disseminated intravascular coagulation (dic) is linked with severe covid‐ , prompting considerable concern. dic can be a devastating systemic disorder. it is often markedly manifest on the skin as acrocyanosis or as petechiae and purpura with progression to hemorrhagic bullae. subcutaneous hematomas may occur, as may thrombotic findings including necrosis and gangrene. this article is protected by copyright. all rights reserved. disseminated intravascular coagulopathy (dic) is linked with severe covid- , as are other covid- -associated coagulopathies (dic) is a clinically striking condition of inflammatory, systemic hemostasis first reported by dupuy in . [ ] [ ] [ ] this activation overcomes anti-coagulation mechanisms, leading to fibrin clot formation within small and medium sized vessels. , , the pathogenesis involves endothelial injury, exposing sub-endothelial collagen, so that microthrombi are formed as the underlying pathology. , hemostasis, along with inflammation, may lead to organ failure, particularly in those that are critically ill. , depletion of coagulation factors leads to risk of serious hemorrhagic complications. , dic may be caused by malignancy, infection, hypoxia, hypoxemia, trauma, burns, vascular disorders, immunologic disorders, toxins, hepatic disease or peri-partum complications. , , , [ ] [ ] [ ] [ ] [ ] [ ] dic may occur with metastatic cutaneous melanoma. acute myeloid leukemia and prostate cancer are the most common causative malignancies. the severity of skin findings in dic has not been classified. the development of dic in patients with covid- unfavorably alters its clinical course . routine monitoring of hemostasis tests is important in selected covid- patients. clinical patterns with dic are varied, exemplified by those identified with covid- , from petechial to acro-ischemia presentations including finger/toe cyanosis, skin bulla and dry gangrene, some resembling chilblains disease (figures , ) . hypercoagulable states in dic are associated with a set of common cutaneous manifestations. in a study of patients with dic, cutaneous findings were the presenting sign in % of them. they were caused by either initial thrombosis or hemorrhage secondary to consumption of coagulation factors. , skin manifestations caused by hemorrhage occur with the following frequencies: petechiae ( %), purpura ( %), palpable purpura ( %), hemorrhagic bullae ( %), subcutaneous dissecting hematomas ( %), or bleeding from wound/iv sites ( %). , skin manifestations caused by thrombosis include acral cyanosis ( %) and gangrene ( %). purpura fulminans is a combination of hemorrhagic and thrombotic findings. in dic, petechiae are miniscule, pin-point sized, macules caused by hemorrhage from skin capillaries. , they are sometimes papular, palpable petechiae (figures , ). purpura is evident as nonblanching, erythematous macules, patches, or plaques varying in size from to millimeters. they may be flat or raised, palpable purpura with clear or necrotic centers. purpura and petechiae become palpable due to increased hemorrhage and edema. purpura is similar to petechiae, but larger and in this setting often has sharply demarcated borders. petechiae and purpura are usually limited to the extremities. they have a propensity to occur in wounds and at pressure points. the purpura may become large and widespread enough to converge and develop into hemorrhagic bullae ( fig ) . when less than hours duration, petechiae and purpura are characterized by thrombi in the superficial vascular plexus at the junction of the papillary and reticular dermis. older lesions contain epidermal necrosis, subepidermal bullae, and glandular necrosis. other hypercoagulable states that cause purpura include thrombotic thrombocytopenic purpura, warfarin skin necrosis, heparin induced thrombocytopenia, calciphylaxis, and catastrophic alpa syndrome. , palpable purpura may be caused by septic emboli, allergic cutaneous vasculitis, drug reaction (penicillin, sulfonamides), or systemic necrotizing angitis. , [ ] [ ] [ ] palpable purpura is the hallmark of leukocytoclastic vasculitis. hemorrhagic bullae are filled with blood. large hemorrhagic bullae may undergo necrosis and gangrenous change and require distinction from erythema multiforme or bullous pemphigoid. bullae in dic must also be differentiated from steven-johnson syndrome, the flaccid bullae in toxic epidermal necrolysis (ten) and dissecting hematomas, which are extensive subcutaneous accumulations of blood that are rapidly progressive and painful. , , dic may also be evident with cyanosis, which appears as a non-blanching, central grey area surrounded by irregular, erythematous or purplish borders. it is most commonly located on the digits, but may also be found on the ears and nose. acral cyanosis may evolve into gangrene. indwelling arterial and venous catheters are associated with a higher risk of acral cyanosis and gangrene. acral cyanosis must be distinguished from raynaud's phenomenon, chilblains, and acrocyanosis. it is important to differentiate the thrombotic/coagulopathic vasculopathic acral ischemia as seen in dic from chilblain-like lesions (blue "covid toes"), also associated with the this article is protected by copyright. all rights reserved. severe disease reflects a hypercoagulable state and highly elevated d-dimer levels. unlike the other skin findings in covid_ , chilblain-like lesions are unassociated with severe disease but may represent a clue to covid- diagnosis . they clinically and histologically strongly resemble idiopathic and auto-immune related chilblains . there are no data to our knowledge to support that acral ischemia and chilblain-like findings are different degrees of involvement within the same spectrum , , . gangrene of hands, feet, tip of the nose, ear, and posterior scalp may occur in dic. symmetrical peripheral gangrene (spg) is gangrene of the acral parts of the body. the hypercoagulable state of dic results in microvascular occlusion beginning distally and advancing proximally. symmetrical peripheral gangrene manifests as fever, followed by cyanosis, pallor, and pain. , there is an association between a cold ambient temperature and the development of gangrene, postulated to be related to increased vasospasm. spg is almost universally associated with dic. gangrene has been found to have a mortality of %. [ ] [ ] [ ] gangrene may lead to osteomyelitis. in one study of patients, died within one week and of the remaining required amputation. there is also some risk of auto-amputation of digits. purpura fulminans, the most fatal presentation of dic, is a dermatologic emergency. it manifests as multiple purple/erythematous, nonblanching, confluent macules, hemorrhagic bullae, and skin necrosis. , purpura fulminans is rapid in onset and extensive. , , late findings in purpura fulminans include geographic plaques, hemorrhagic bulla, gangrene and firm eschar. , , the distal extremities are most commonly involved, but any part of the body is susceptible. , it is associated with high mortality due involvement of visceral organs. , , multiple organ failure makes dic difficult to distinguish from ten. , other causes of purpura fulminans include congenital protein c/s deficiency, sepsis, trauma, malignancy, obstetric complications, hepatic failure, toxins, or immunologic reactions. dic may manifest at varying degrees of severity. one study found that % of patients presented with petechiae, % with purpura, % with palpable petechiae or purpura, % with acral cyanosis. % of purpura progressed to hemorrhagic bullae. two patients progressed to purpura fulminans. palpable purpura was usually found in association with n. meningitidis infection. the combination of septic shock, palpable purpura, and acral cyanosis is very suggestive of dic. etiology (table ) sepsis, particularly bacterial sepsis, is the condition most commonly associated with dic. more than half of covid- pneumonias admitted to intensive care at a large texas hospital developed clinically significant thromboses that were associated with hypercoagulable thromboelastographic parameters alone . in fact, - % of patients with gram-negative sepsis have dic, but it is just as common in those with gram-positive sepsis. , systemic coagulation is activated by lipopolysaccharide, endotoxin, or this article is protected by copyright. all rights reserved. exotoxin. trauma, particularly brain trauma, results in dic by the release of fats and phospholipids, hemolysis, and endothelial damage. both solid and hematologic malignancies cause dic due to expression of tissue factor on tumor cells. purpura fulminans is associated with a deficiency of protein c or protein s. it is commoner in children than adults, usually linked in the former with scarlet fever, varicella, or pneumococcal infection. a cutaneous biopsy specimen may be beneficial in establishing the diagnosis, but the diagnosis is mainly clinical ( table ). dic is characterized by fibrin thrombi within capillary walls. , these fibrin thrombi lack the associated inflammation that is seen in vasculitis. many histochemical stains can aid in the identification of vascular occlusion. fibrin is strongly pas positive. it also shows a deep blue color with phosphotungstic acid hematoxylin. fibrin colors bright red on carstairs' stain, which is a picric acid-acid fuchsin-based stain. platelets are gray-blue using this stain. immunofluorescent staining with antifibrin serum yields positive results. after vascular occlusion, endothelial cells become edematous, resulting in capillary congestion. this article is protected by copyright. all rights reserved. there is no definitive blood test to diagnose dic. most patients show depletion of coagulation proteases and thrombocytopenia. , , depression of coagulation factor levels is due to consumption, as well as decreased production. low platelet count, although characteristic of dic, is not a specific finding. more than % of critically ill, postoperative patients have less than , platelets/ul. , - % of patients with dic will have platelet counts below , . compared to those with normal platelet levels, these individuals have an enhanced risk of developing hemorrhagic complications. , the differential for thrombocytopenia due to dic includes sepsis, impaired production, blood loss, hypersplenism. this article is protected by copyright. all rights reserved. the prothrombin time (pt) is prolonged in dic. , due to its standardization, many centers are beginning to use inr instead of pt time. an abnormal pt or aptt is found in most patients with dic. the differential for an elevated pt includes hepatic failure, blood loss, and vitamin k deficiency. the differential diagnosis for an elevated ptt includes hepatic failure, blood loss, and heparin therapy. the levels of factor are increased in dic because it, along with von willebrand factor, is released from injured vascular endothelial cells. , measurement of fibrinogen level has no proven utility in the diagnosis of dic. , fibrin degradation products are increased in dic. , , they are elevated in % of critically ill patients, % of trauma patients, and nearly % of dic patients. , as such, the specificity of fibrin split products is not high. the differential includes hematoma, post-op status, systemic inflammation, deep vein thrombosis, and pulmonary embolism. inhibitors of coagulation, such as protein c, protein s, and antithrombin, are decreased in % of patients with dic. the reason for their decrease is consumption, decreased production, and increased processing by neutrophil elastase. , other causes include hepatic failure and capillary leakage. the international society on thrombosis and hemostasis has created a composite scoring system to assess the likelihood of coagulopathy. this scoring system is based on platelet count, pt, d-dimer, and fibrinogen levels. if the score is greater than or equal to out of , then it is considered compatible with overt dic. other scoring systems that rely on inr instead of pt are pending widespread validation. the higher the composite score, the lower the survival rates. the scoring should be repeated daily if it is greater than or equal to . prolonged elevation of pt and platelets has been affiliated with poorer outcomes. , a gold standard does not exist for the ideal diagnostic criteria, but three are primarily used throughout the world. , , patients with dic can show signs of organ failure. , blood cultures may show growth of a causative organ, such as staphylococcus aureus, group a streptococci, neisseria meningitidis, vibrio species, varicella virus. , , , , , , one study reported n. meningitidis as the most common causative organism. if other laboratory tests are equivocal, a punch biopsy specimen of cutaneous lesions may reveal fibrin thrombi. , treatment treatment of dic usually requires a multidisciplinary approach in an intensive care unit. , therapy of dic is not directed at the skin, but rather at the management of the causative condition. , , - covid- -associated dic therapy should follow accepted strategy employing thromboembolic prophylaxis for critically ill hospitalized patients and standard supportive care measures . however, a lack of thrombocytopenia may mean that covid- dic is not always a typical consumptive coagulopathy with additional this article is protected by copyright. all rights reserved. strategies possibly necessary . transfusion of platelets, plasma, cryoprecipitate or fibrinogen concentrate should be considered for hemorrhaging patients. , , , patients with dic due to infection should have it treated, depending on the causative organism. leukopenia is a poor prognostic factor. resection of necrotic tissue, including escharotomies, may be required. skin grafting should be performed, if possible. , amputation of gangrenous areas may be compulsory. , , while patients are being optimized for treatment, padding or vascular boots may be applied to the affected parts. improvement of the dermatologic findings is a useful measure in determining response to therapy. with covid- producing florid dic in some hospitalized patients and acral cyanosis in variety of settings, dic has risen to the forefront with no clear therapy yet of proven value for the covid- itself , , , , preliminary data suggests that low dose dexamethasone may reduce deaths in hospitalized covid- patients on ventilation, although its effects on dic in this setting are yet to be determined . one must also watch for co-infections, as the covid- pandemic may merge with the candida auris global epidemic in the intensive care unit with dic being produced by either and possibly both of them . references: mortus this article is protected by copyright. all rights reserved. with coronavirus disease who are critically ill thromboelastometry in critically ill patients with disseminated intravascular coagulation prominent changes in blood coagulations of patients with sars-coc- infection zhonghua xue ye xue za zhi.

consequently, in the case of otherwise asymptomatic patients, we canreassure them, without referring them to hospital to perform any sort of covid- test, or quarantining them. this article is protected by copyright. all rights reserved. this article is protected by copyright. all rights reserved. this article is protected by copyright. all rights reserved. chilblain-like lesions during covid- pandemic: a serological study on a case series no evidence of sars-cov- infection by pcr or serology in children with pseudochilblain chilblains in children in the time of covid- : new evidence with serology assay a clinical, histopathological and laboratory study of consecutive italian paediatric patients with chilblain-like lesions: lights and shadows on the relationship with covid- infection online ahead of print pernio-like skin lesions associated with covid- : a case series of patients from countries chilblain-like lesions in pediatrics dermatological outpatients during the covid- outbreak evaluation of chilblains as a manifestation of the covid- pandemic covid toes"): histologic, immunofluorescence and immunohistochemical study of cases no antibody response in acral cutaneous manifestations associated with covid- ? acute acral cutaneous manifestations during the covid- pandemic: a single-centre experience major cluster of pediatric " true " primary chilblains during the covid- pandemic: a consequence of lifestyle changes due to lockdown assessment of acute acral lesions in a case series of children and adolescents during the covid- pandemic recent outbreak of chilblain-like lesions is not directly related with sars-cov- infection igm/igg duo assay igm/igg rapid test igm: . % igg covid- elisa kit, vircell, igm/igg+iga igm+iga: % igg: % igm+iga: % igg: % key: cord- -vb ks mq authors: damiani, giovanni;

[ % ci . ‐ . ], p = . ), however, not increased risk of icu admission or death were found. pso patients on biologics should be carefully monitored with telemedicine during covid‐ outbreak and early treated at home to limit hospital overwhelm. since march , , lombardia region experienced covid- lockdown and only after days the entire italy became red-zone. nowadays, lombardia is the italian region with more confirmed, hospitalized, and dead covid- patients. despite the higher risk for covid- displayed by obese, active smokers, and copd patients, almost no data are present toward psoriatic (pso) patients and biologics. moderate to severe psoriasis benefit from systemic treatment as biologics and small molecules; at the same time these drugs, capable to clear psoriasis, are related also to an increased risk of airway infections. pso patients also display a baseline airway inflammation that triggers the constellation of chronic respiratory comorbidities, such as asthma and chronic obstructive pulmonary disease (copd). furthermore, pso patients are frequently smokers and cigarettes increased flares as well as psoriasis severity, predisposing to copd and exacerbating asthma crisis. thus, we performed this study aiming to understand the effect of biologics in pso patients during covid- outbreak focusing on symptomatic patients quarantined at home, hospitalized, and their prognosis. pso patients on biologics displayed higher risk to be infected and to be hospitalized/self-quarantined at home, but icu hospitalization and death did not differ from the general population. notably, pso patients display baseline airway inflammation that clears with anti-pso therapies, preliminary data suggest that airways inflammation is downregulated by treating skin inflammation. the lung-skin inflammatory reciprocal interactions was modelized by nadeem et al claiming that skin inflammation via il- /stat signaling modulates airway inflammation and vice versa. these findings offer also a rationale to continue biologics in pso patients to prevent the lung-skin inflammatory axis and to inhibit the progression to the hyperinflammatory phase. despite this study is the first to assess the impact of biologics among pso patients during covid- , it did not assess the family members, so future studies should also evaluate this aspect. biologics may not increase the risk of icu hospitalization and death; however, they increase the risk of mild to moderate disease. thus, pso patients on biologics should be carefully monitored with teledermatology and early treated at covid- symptoms early onset. clinical features and short-term outcomes of patients with covid- in wuhan safety of systemic agents for the treatment of pediatric psoriasis psoriasis and respiratory comorbidities: the added value of fraction of exhaled nitric oxide as a new method to detect, evaluate, and monitor psoriatic systemic involvement and therapeutic efficacy lifestyle changes for treating psoriasis covid- illness in native and immunosuppressed states: a clinical-therapeutic staging proposal a subset analysis of efficacy and safety outcomes from phase clinical studies of ixekizumab for the treatment of patients with severe plaque psoriasis why tocilizumab could be an effective treatment for severe covid- ? increased airway inflammation in patients with psoriasis psoriatic inflammation enhances allergic airway inflammation through il- /stat signaling in a murine model biologics increase the risk of sars-cov- infection and hospitalization, but not icu admission and death: real-life data from a large cohort during red-zone declaration the authors declare no potential conflict of interest. https://orcid.org/ -

weeks) in pco patients with moderate-to-severe nodulocystic acne resulted in significant decreases in levels of serum total testosterone, prolactin, and dihydrotestosterone but increased dehydroepiandrosterone levels. in nutshell, till further studies on the multifaceted pathogenesis of covid- infection, we suggest low, lid-dose of isotretinoin with folic acid supplement, together with proper nasal mucosal care for isotretinoin patients. isotretinoin treatment should be questioned in all covid- suspected patients presented with nasal/olfactory dysfunction symptoms. low dose of isotretinoin: a comprehensive review adult acne versus adolescent acne: a retrospective study of , patients characteristics of and important lessons from the coronavirus disease (covid- ) outbreak in china: summary of a report of cases from the chinese center for disease control and prevention rapid asymptomatic transmission of covid- during the incubation period demonstrating strong infectivity in a cluster of youngsters aged -

recommendations for treatment of patients with psoriasis at time of new covid- pandemic. the authors pointed to the importance of therapeutic reassessment of all psoriatic patients, particularly those with moderate-to-severe disease, who are candidate to systemic, mostly immunosuppressive, therapies in the era of covid- . the authors recommended topical and/or drugs with a lower impact on the immune system to avoid spread of the infection. though of interest, we have few points to comment on these recommendations based on the current literature review. psoriasis is a worldwide systemic inflammatory disease that has been associated with a number of comorbidities and increased mortality. older patients with moderate-to-severe disease are more prone to cardiovascular and neurological comorbidities, such as hypertension and dementia, respectively. independent of treatment, there is a twofold increased risk of serious infections among older adults with psoriasis compared to those without psoriasis. covid- -infected patients with hypertension are associated with higher rate of morbidity and mortality. covid- virus has neurotropic potential that partially explains the higher rate of acute respiratory distress in elderly patients. the tumor necrosis factor-α inhibitors, adalimumab is currently under evaluation for use in treating severe covid- pneumonia. unwise patients stopping biologics temporarily with or without their physician recommendation may lead to development of antidrug antibodies, and possible loss of response when these drugs reintroduced. , according to a very recent study testing direct acting antiviral drugs against covid- model, the author noted that sofosbuvir, ribavirin, and remedisvir can tightly bind to covid- rnadependent rna polymerase and contradict its function leading to viral eradication. that would be plausible for patients living in hcv-high prevalent countries, such as italy. ultraviolet a (uva ) phototherapy has a comparable efficacy in moderate-to-severe plaque-type psoriasis and could improve the clinical manifestations and quality of life more quickly than narrow band ultraviolet b therapy with no significant side effects, including lack of increased risk of cutaneous malignancies. , with the recent covid- outbreak, dermatologists should prioritize and individualize treatment protocols to psoriatic patients based on diseases severity, patients medical conditions, and viral invasiveness. for biologics in the precoronavirus era, respiratory infection rates were comparable to placebo. biologics may be tried in elderly patients with psoriasis. for the absolute highest risk patients, those with cardiovascular and pulmonary comorbidities, the risk-benefit may favor discontinuation on a case-by-case basis. uva may be also considered. hcv-positive patients coinfected with covid- may benefit from direct acting antiviral. in other word, patients ranking for aggressive or conventional treatment modalities

in the literature, cutaneous symptoms related to the disease are generally emphasized. however, it is not yet known whether this new sars-cov- virus, which has entered our lives, plays a role in the

before and after the pandemic. covid- has already had many effects on the routine dermatology practice ( ) . however, it is clear that there will be many more developments and new information in the relationship between covid- and dermatology in the following days. sars-cov- , which is the cause of covid- disease, is not actually a dermatotrophic virus. however, various cutaneous manifestations associated with the disease have been reported to develop during covid- disease ( , ) . cutaneous symptoms can be classified under five main categories (urticarial lesions, livedo and necrosis, maculopapular eruption, vesicular rash, pseudo-chilblain) ( ). however, dermatological diseases triggered by sars-cov- remain a mystery for now. in our study, it was found that the rate of pityriasis rosae patients who applied to the dermatology outpatient clinic this year during the pandemic period increased approximately times compared to the same time last year. the fact that there was no significant increase in the total number of pityriasis rosae patients was attributed to the low number of total admissions to the hospital during the pandemic period. in our opinion, the increase in the rate of pityriasis rosae patients among polyclinic patients was more important data. previously, a case of pityriasis rosea associated with covid- disease has been reported ( ) . our findings are the first study in the literature showing the increase of pityriasis rosea patients and their relationship with covid- . pityriasis rosea has been mostly associated with reactivation of human herpesvirus and , but other viral etiology, vaccination, psychological stress, and drugs have also been implicated as the cause of this reaction ( ) . hhv- , a member of the herpes virus family, is usually transmitted in the first two years of life (roseola infantum) and settles in the salivary glands, causing a latent infection ( ) . there are two types of hhv- , a and b ( ) . the reactivation of hhv- is blamed for many diseases, including pitriasis rosae ( ) . it has been argued that one of the factors causing activation of herpes viruses is coronaviruses ( ) . along with the covid- pandemic, it was thought that reactivation of hhv- could explain this obvious increase in pityriasis rosea cases. another possible trigger could be psychological stress caused by the pandemic period. kawasaki disease is a systemic vasculitis of childhood that can affect the coronary arteries. the diagnosis of kawasaki disease is based on clinical features. cutaneous symptoms with diagnostic criteria are: erythema of the mouth or pharynx, strawberry tongue, or stomatitis; polymorphous rash; erythema or edema of the hands or feet ( ) . the etiology of kawasaki disease is still unknown. hhv- is one of the accused reasons for the etiology ( ) . in a study conducted during the covid- pandemic, kawasaki disease was found to increase -fold compared to previous years ( ). in our study, there was a -fold increase in the rate of patients with kawasaki disease who applied to the dermatology outpatient clinic compared to the previous year. we think that this increase in kawasaki disease during the covid- pandemic may be due to coronavirus triggering of hhv- , which is responsible for the etiology. the covid- disease caused by sars-cov- still contains great mysteries for dermatology. in order to solve the mysteries about the disease, a lot of data are published about the clinical symptoms caused by the disease, the effects and side effects of drug treatments, and the associated diseases. kawasaki disease has been reported to increase compared to previous years. however, there is no data to show the increase of pityriasis rosae patients in which hhv- plays a role in etiopathogenesis, as in kawasaki disease. our study is the first study showing pityriasis rosea increase during pandemic period. we think that this increase is related to hhv- reactivation. herein, we

drastic interruptions in traditional dermatologic patient care globally. safety procedures have been implemented to protect patients and providers, some of which may interfere with effective communication for deaf and hard of hearing (dhh) patients, who already face significant challenges. hearing loss has been associated with increased health care expenditure and resource utilization, making it more difficult for dhh patients to receive appropriate care. in this letter, we make recommendations for mitigating communication barriers for dhh dermatological patients during the covid- pandemic. in-person dermatological care has changed, mandating the use of personal protective equipment this article is protected by copyright. all rights reserved. professional interpreter is not available, a smartphone speech-to-text app can be utilized to create automated captions. to limit risk of covid- transmission, dermatology practices have dramatically reduced inperson visits and increased utilization of telemedicine and telephone calls, posing significant and unique challenges to dhh patients. televisits with dhh patients should employ -way video conferencing with a sign language interpreter. dermatologists may also provide a visual prop with photographs of various skin morphologies and questions about symptoms, such that patients may respond to questions even with limited hearing. if an interpreter is not available for video conferencing, dermatologists should facilitate the encounter via telephone, so that dhh patients may use their preferred telecommunication relay service. this system utilizes an operator who voices the typed conversation to the physician and then types the responses back to the dhh patient, such that communication can occur using a standard telephone. written instructions on taking photographs of the area of concern should be given prior to telephone calls. images must be in-focus, with multiple viewpoints, and a coin or ruler can be placed in the frame for scale. the covid- pandemic requires that dermatologists be creative in providing dhh patients with timely and effective care. strategies used for each dhh patient will vary depending on severity of hearing loss, and language and communication preferences. we hope that this letter will make our dermatology community more sensitive to the needs of dhh patients and that these recommendations will be useful in diagnosing and treating these patients both during and following this pandemic. this article is protected by copyright. all rights reserved. this article

journal: dermatol ther doi: . /dth. sha: doc_id: cord_uid: r xm s background: during the outbreak of covid‐ many pernio‐like lesions have been increasingly reported. the aim of the study is to describe our management of these skin manifestations and to evaluate a possible correlation to sars‐cov‐ infection. methods: all patients underwent clinical and laboratory tests to detect a possible underlying connective disease and also to specific sars‐cov‐ investigations such as oropharyngeal swab and igg‐igm serology. results: nine patients aged between five and fifteen years old were evaluated. skin lesions observed were purplish, erythematous and oedematous, in some cases painful and itchy. six out of nine had respiratory and systemic symptoms (cough, nasal congestion, chills, fever, asthenia) that preceded cutaneous findings of approximately two weeks. concerning blood exams, three out of nine had d‐dimer weakly increased, four had ana positivity: two with a title : , one with : and one with : and a speckled pattern. the latter patient had also ena ss‐a positive and rf positivity, confirmed at a second check, so as to allow us to make a diagnosis of connective tissue disease. four out of nine had apl positivity (igm). reactants acute phase were all negative. oropharyngeal swabs and serology tests for sars‐cov‐ was negative (borderline in one patient for igm). no treatment was needed. conclusions: even if we do not have enough data to prove it, we hypothesize a correlation between pernio‐like lesions and sars‐cov‐ infection for an increased number of these lesions described during the pandemic and also because such manifestations appeared when temperatures were mild and patients were at home in isolation for the lockdown. many questions remain open about interaction host‐virus. this article is protected by copyright. all rights reserved. during the outbreak of covid- many skin manifestations have been reported, and among these, in very significant numbers, newly vascular eruptions and peculiar pernio-like skin lesions have been described in observational studies , , , . pernio, also referred to as chilblains, is a rare inflammatory condition. chilblains derives from two old english words "chill" (cold) and "blegen" (sore). most commonly, pernio affects acral skin and develops among susceptible individuals who are exposed to cold, the lesions usually appear in fall or winter and disappear in spring or early summer. it is typically idiopathic and acute, nevertheless chronic forms also exist . the diagnosis of pernio is largely clinical and based on a thorough history and physical exam. the differential diagnosis must exclude diseases that can often be confused with other forms of pernio or vasculitis processes like systemic lupus this article is protected by copyright. all rights reserved. erythematous (sle) or other conditions as raynaud phenomenon, acrocyanosis, cryoglobulinemia, cold panniculitis and interferonopathies. the prognosis of pernio is good with minimal chronic sequelae. single or multiple erythematous, purplish, edematous lesions appear, accompanied by intense pain, itching, or burning. usually, pernio affects the toes and dorsum of the proximal phalanges . the mainstay of treatment is the avoidance of the cold and, in some cases, drugs as nifedipine and other calcium channel blockers are needed for the resolution of existing lesions . since march , children with acral red and painful skin lesions, referable to chilblain have come to our attention. the increased number of cases of pernio-like lesions compared to the cases per year we usually observe, the mild temperatures of those months in southern italy and the concomitant lockdown, led us to hypothesize a possible correlation with sars-cov- infection. we evaluated the personal history and photographs of skin lesions of patients, sent to us by their pediatrician, through multidisciplinary telematic meetings with dermatologists, rheumatological pediatricians, infectious disease specialist. we only included patients with pernio-like skin lesions (nine patients). patients who could not perform the oropharyngeal swab for sars-cov- were not admitted to the hospital. we collected informed consent to obtain clinical information and photos of patients and to perform blood chemistry sampling. therefore, we evaluated cases of children who in our group of patients no significant difference in gender was detected ( females and males). the median age was , years (from to years). two patients were siblings. all patients were from the south of italy coming from the town of messina and surrounding. their family histories and their personal histories were negative for autoimmune disorders, raynaud's phenomenon, acrocyanosis, chilblains or photosensitivity except for one child who had suffered from an episode of raynaud's phenomenon a few years earlier. no family member of these patients presented symptoms attributable to sars-cov- infection but, for work reasons, their parents were in contact with public. only two siblings had both parents with compatible symptoms and confirmed sars-cov- infection by positive nasal swab. the cutaneous manifestations observed were purplish, erythematous and edematous, four children reported subjective symptoms, painful and pruritus localized to the sole of the feet or to the toes and/or fingers or heels ( fig. , , ). feet alone were mostly affected ( out of ), hands alone ( out of ) (fig. ) . six patients had respiratory and systemic symptoms (cough, nasal congestion, chills, fever, asthenia) that preceded the skin lesions by about two weeks (table ). this article is protected by copyright. all rights reserved. we evaluated cases of children who presented pernio-like lesions, since march to april during the outbreak of covid- . we performed first level tests, all negative except for d-dimer weakly increased in three of our patients. d-dimer is a marker of activation of coagulation and fibrinolysis and it provides a rapid evaluation of thrombotic activity. its level correlated to coagulopathy have been described as prognostic factors in the evolution of sars-cov- infection, especially in more severe patients. zhang's study developed a triage, testing d-dimer levels at the admission, on the first and third day to predict survival in a cohort of patients and to evaluate management and follow up. the result was that a regulatory level of d-dimer at the presentation is highly predictive for survival . this is useful to highlight, as in our case, the d-dimer of our patients was weakly increased, a condition perfectly correlated with the mild symptoms of sars-cov- putative infection presented. we have also performed autoimmunity tests, three out of nine had ana positivity (speckled pattern): two with a title of : , one : not confirmed at a subsequent check after two months, another asymptomatic cases generated specific antibody responses for sars-cov- . the case of our family is emblematic: two parents presented striking symptoms of sars-cov- infection, high fever and this article is protected by copyright. all rights reserved. difficulty in breathing, and three positive swabs; the father had positive serology with high igg, such as to allow donation of his plasma for therapeutic purposes and the mother was surprisingly negative. sons who came to our observation, both with chilblain, presented mild respiratory symptoms and they were negative for both swabs and igg serology, while in one of the two cases, the igm were borderline. despite the negativities of diagnostic test for sars-cov- , we are still convinced that there is a correlation between this infection and the development of pernio-like lesions, as described nasopharyngeal swab for sars-cov- gave negative results . in a report of adolescent patients with a clinical diagnosis of pernio-like lesions nasopharyngeal swab and igg serology for sars-cov- nucleocapsid protein were negative. importantly, iga serology for s domain of sars-cov- spike protein was positive in patients and borderline in patients . in a study performed in sicily (italy) via teledermatology a total of patients complaining of perniosis-like lesions were screened, mainly in the pediatric age (≤ yrs). all of them were tested with rhino-pharyngeal swabs and sars-cov- was detected in patients, of whom were children . the understanding of the immunopathogenetic mechanisms of interaction between the sars-cov- infection and children is very intriguing but current knowledge does not seem to be sufficient. why some children who come into contact with the sars-cov- do not develop striking respiratory symptoms but present pernio-like lesions with negativity on diagnostic tests? matricardi et al developed the first model of interaction between the human immune system and sars-cov- , as an attempt to produce a synthesis of the actual knowledge . what emerges is that innate immunity represents the first line of defense against the new sars-cov- and this first comparison establishes the natural history of the pathology: either the infection will effectively block in the upper airways or if the virus manages to reach the lungs. innate immunity is essential for controlling virus replication before an adaptive immune response is generated . type i interferones (ifn-i) are major components of the innate immune system and it represents critical antiviral molecules . it is hypothesized that the ifn-i response may induce microangiopathic changes, producing chilblains and lupus-like erythematous eruption. a mechanism has recently been considered to explain the appearance of autoimmune phenomena following the whole sars-cov- infection: molecular mimicry , , . lucchesi and floel have hypothesized a molecular mimicry mechanism between neuronal proteins present in the brain stem respiratory pacemaker neurons (dab , aifm and surf ) and viral epitopes of sars-cov- treated antigenic. the same mechanism, according to angileri et al., could be responsible of anosmia, leukopenia and multi-organ failure caused by vascular damage, assuming they are associated with the molecular mimicry . a type hypersensitivity therefore occurs with the deposition of antibody antigen complexes precipitating inside the tissues, in particular the blood vessels, inducing a serious inflammatory state by the action of the complement anaphylatoxins (c a and c a), which in turn stimulate the release of histamine from mast cells and the recruitment of phagocytes, first in neutrophils, the main cause of tissue damage and following «leukocytoclastic vasculitis» (lcv), also reported in the english medical literature from the term «hypersensitivity vasculitis , ». this pathogenic mechanism could explain the appearance of pernio-like lesions due to sars-cov- infection. in conclusion, we think there is a correlation between pernio-like lesions and sars-cov- infection, but further studies are needed to prove it. this, for the increased number of these lesions described during this short time, as in our experience, and because such manifestations appeared when temperatures were mild in southern italy and patients were at home for the lockdown. to our knowledge, this is one of the few studies that collects a series of pediatric patients with perniolike lesions, evaluating the possible association with covid (oropharyngeal swab and serology test) but also for rheumatological

intensive care unit (icu). we visited directly, got information about their medical history and took clinical images. the diagnosis of the patients was made according to computed tomography (ct) or reverse trancription-polymerase chain reaction (rt-pcr) results. rt-pcr test of nasophrygeal or throat swabs is the gold standard for the diagnosis of covid- however it is time consuming and may yield false-negative results ( ) . although the rt-pcr was negative, patients were hospitalized when the ct findings were positive. the typical imaging characteristics of patients with covid- are single or multiple ground-glass opacity with subpleural distribution, crazy paving and diffuse consolidation with ground-glass opacity ( ) . rt-pcr and ct were performed to all patients and findings were recorded. clinicopathologic confirmation of the patients could not be made due to the pandemic conditions. all patients gave their informed consent to participate and an explicit consent to use their

reported on the possible association between covid- and skin lesion severity in patients. in patients ( . %), the severity of cutaneous lesions was unlikely to be or was not correlated with covid- severity. contrarily, in separate reports by mahe and estébanez, covid- and skin lesion severity were linked in patients ( . %) ( ) . the patients who had comorbidities showed a greater percentage of

erythematous scaly rash in our study. the increased frequency of hand-washing and the use of the disinfectants increase the risk of irritant contact dermatitis ( ) . maculopapular skin rash and urticarial rash were the second and third most commonly seen cutaneous manifestations. maculopapular rash was most commonly seen on the trunk; urticarial lesions were generalized. maculopapular lesions and urticaria may occur due to covid- disease itself or the antiviral drugs used in the treatment ( ) . the increased frequency of maculopapular rash and urticaria in our study group is in alignment with the previously reported literature ( , , ) . petechial and purpuric lesions and necrosis were also observed in our study group. a case series from china reported vasculopathic skin lesions ranged from acral cyanosis to dry gangrenes in patients ( ) . unlike the previously reported publishings, neither "chickenpox-like vesicles' nor chillblain-like symptoms were not observed in our study. there was only one patient with the diagnosis of pernio. the limitation of our study was that we just evaluated the hospitalized patients, and we could not perform clinicopathological confirmation. our study is the first prospective study that evaluates the patients' cutaneous findings at the covid- wards or the covid- icu in turkey. in this regard our study may give an opinion to the dermatologists about moderate/severe covid- infections' cutaneous manifestations. table . age group and cutaneous findings table . gender and cutaneous findings table . pcr result and cutaneous

this part the lack of sufficient data concerning the interaction of sars-cov- and biologics is also an important factor that should be taken into consideration when examining the option of initiating therapy with the latter. another logistic parameter that should not be underestimated is the need of frequent careful monitoring under such treatments that includes both regular laboratory examinations as well as routine dermatologic follow-up visits, which could constitute a problem under the emerging societal circulatory restrictions that are posed in order to control the pandemic unnecessary biologic discontinuation would lead to a worsening of psoriasis and psoriatic arthritis in a high percentage of the cases. as a consequence, there may be higher disease n, destructive impact on quality of life, burde as well as increased health care costs due to the augmented number of consultations and recovery. furthermore, the unavoidable subsequent return to biologic therapy could be cost associated with switching toward higher known lower efficacy of -drugs, due to the well biologics in the same patient after their interruption coronavirus widespread quickly across the world and in the march ,who announced the pandemic condition ( ) . there is necessity to paying more attention to skin and its appendix (hair, nail) and the mucosal manifestation of covid also being

had many concerns about patient who are suffering from chronic dermatologic disorders which needed to have repeated follow ups or who are on immunomodulator agents specifically immunosuppressives that are needed to be controlled without any more risk to getting infected with covid or getting involved with its consequences. this article is protected by copyright. all rights reserved. according to

maculopapular lesions %, urticarial eruption %, acral erythematous lesions with pustule or vesicle (chilblain like lesion) %, other vesicular lesions %, and livedo reticularis % ( ). there were several drug regimens used for treatment of covid- patients, some of which could result in cutaneous side effects like presence of a new dermatoses or flare/aggravation of a previous dermatologic disorder. till to the last update of this systematic review, generalized pustular reaction and exacerbation of psoriasis due to hydroxychloroquine were the reported cases of cutaneous adverse reaction of covid- treatment ( , ) (supplementary table ). the following is the most common adverse reactions found in the publications irrespective of this pandemic, yhat could be in mind for better dermatologic disease approaching (supplementary table ). hydroxychloroquine; despite the inconclusive result over the implication of anti-malarial drugs; it is used widely for treating covid- patients. in a study by sharma et al., a total of unique dermatologic reactions were reported in patients had hydroxychloroquine cutaneous adverse drug reactions. the most common was drug eruptions as in maculopapular, erythematous, and urticarial dermatosis. hyperpigmentation came second followed by pruritis, sjs/ten and agep(acute generalized exanthematous pustulosis) ( ) . dermatologists should consider the covid- cutaneous manifestations such as erythematous rash, petechia, urticaria as differential diagnosis while assessing the possible hydroxychloroquine drug reactions ( ) . azithromycin; azithromycin is another drug used in combination with hydroxychloroquine in covid- treatment regimens. skin adverse events of it may include cutaneous severe skin reaction associated fever, generalized red or purple skin rashes, angioedema, blisters, skin peeling, burning sensation in eyes or painful skin ( ) . antiviral drugs; several antiviral drugs are used for its treatment as well; including oseltamivir which could result in sjs/ten, angioedema and idiosyncratic cutaneous drug reactions. ribavirin also may cause alopecia, acneiform eruptions, maculopapular and eczematous lesions, localized scleroderma, skin dryness and rash. other anitiviral drugs such as antiretrovirals are also used in some patient including lopinavir and ritanavir. their adverse effects my presented as maculopapular drug eruptions, exfoliative erythroderma, sjs/ten, severe cutaneous drug reactions, injection site reactions ( , ) . in overall, non-infected non-at risk patients with immune-medicated dermatologic disorders under usage of immunosuppressive immunomodulator drugs like biologic agents are not needed to be alter regimen or discontine the therapies during pandemic, even these drugs may control the deteriorating cytokine storms also prevented disease flare-ups which both were associated with poorer outcomes and more complications in covid- course, although strict adherence to quarantine and personal-social preventive hygiene performances are highly recommended especially in these groups of patients. but in patients who are living in highly prevalent disease area, showing flu like or covid- specific symptoms (anosmia or asthenia) or who are highly suspected to having had any positive exposures, based on the consult with their physician and considering all circumstances, it is better to have changing in their therapeutic regimens as dose reduction, dose interval increase or temporary discontinuation. patients with an active covid- infection should hold the biologic or non-biologic immunosuppressants until the complete recovery (at least weeks). in patients who were symptomatic but were no definite cases, therapies should stop for at least weeks. most of skin diseases which were treated with systemic immunomodolators were usually associated with more severe covid- morbidity. dermatologic disorders which were associated with metabolic syndrome, older age or vital organ comorbidities in particular respiratory disorders like patients with psoriasis, hidradenitis suppurativa and atopic tendencies may have poorer prognosis if become infected. patients with more severe skin disorders (e.g. severe psoriasis) were in higher risk for developing pneumonias by any cause that is of great importance in this pandemic. in overall these group of patients may benefit more from future sars-cov- vaccination. since the chronic nature of this pandemic, specialists should decide based on recent evidence with regard to case-by case variations considering cost-benefit ratio and also disease psychological burden ( , , , , ) . biologic immunomodulators especially tnf-a inhibitors, janus kinase (jak) inhibitors, anti-il (tocilizumab) may capable to control cytokine storms and it was systemic consequences like ards and etc in covid- course and some trials were conducted to evaluate their efficacy in disease management, so patients who are using these drugs do not be needed to disrupt ( ) . here in we discuss about experts' recommendations of management of specific cutaneous diseases during pandemic: *virus could act as target mimicry in immunobullous disorders and may trigger or aggravate disease course but it is not recommended to do not treat properly, since poor disease control have its own consequences; even probable more severe and complicated covid- infection; due to deregulated inflammatory storms. *there were not exact data about incidence of covid- in psoriatic patients who are under treatment *risk of hospitalization or death is were not higher than normal population in psoriasis patients under treatment with immunomodulators by itself, but psoriasis may be associated with comorbidities like metabolic syndrome especially in elderly people that is associated with higher mortality rate of covid- infection * monotherapy with immunosuppressives, targeted therapies and lack of comorbidities

emergency. - a significant number of infectious diseases, including human covs, display seasonal patterns in their incidence. environmental factors such as temperature and humidity play an important role in progression and spread of severe acute respiratory syndrome (sars)-cov infection with the virus retaining its viability for over days at temperatures of c to c and relative humidity (rh) of % to %. higher temperatures and higher rh ( c, and > % rh) have been found to reduce virus viability. , covid- , caused by sars-cov- , started in low temperature areas of china, with major outbreaks following in south korea, japan, iran, and northern italy. it is noteworthy that the new epicenters of virus showed similar temperature and latitude and were all along the to n zone. the diseases then spread to higher temperature areas like india, thailand, and middle east, which can be attributed to the global traveling. weather patterns in covid- ( c- c and %- % rh) are similar to those of sars-cov mentioned above and known laboratory conditions that favor cov survival ( c, %- % rh). nevertheless, the dynamics of viral transmission depend on many other factors like physical property of the virus, outdoor and indoor environments, population densities, hygiene, space, and genetic predispositions, which may be the reason for its spread in relatively warmer areas. , the presence of central air-conditioning, which tends to maintain a lower ambient room temperature, may play a role in virus spread in closed spaces irrespective of the outside temperature. lack of hygiene, close contact as seen in high density population areas, poor living conditions with lack of ventilation may be predisposing factors for viral transmission in warmer areas. , the seasonality and dynamics of

paradigm of an aesthetic practice during the covid‐ pandemic: an expert consensus date: - - journal: dermatol ther doi: . /dth. sha: doc_id: cord_uid: wp vh c until vaccination for the sars‐cov‐ becomes a reality, it appears that the infection is here to stay. with many countries lifting lockdown restrictions, aesthetic clinics have started reopening with strict standard operating procedures in place. it is pertinent that the physician today understands the infection, disinfection measures, and personal protective equipment to reduce chances of viral transmission and provide safe clinical settings for oneself, the staff and the patients. an online meeting of eight experts in the field of aesthetic dermatology was convened, which particularly focussed on ppe in detail, risk categorization of aesthetic procedures, preprocedure recommendations, and generalized and specialized sop's for aesthetic procedures. these recommendations were aimed to bridge the gap between published guidelines and clinical practice and are by no means fully conclusive, but signify learnings over the past few months in an active clinical aesthetic practice. the sars-cov- pandemic has changed the homeostasis of the medical world, affecting millions worldwide. amidst the global crisis, other than the health implications, there are major consequences on the world economy. in light of this massive economic slowdown, many nations have ended their lockdowns, albeit on shaky ground. with reopening of services in many countries, dermatology and aesthetic clinics, which were staring at a bleak future, have started opening up with strict standard operating procedures (sop's) in place. in any pandemic, the need to feel good is inherent to a healthy mental-well-being, and wishing away the need for an aesthetic practice as "nonessential" may appear weak to some. while certain guidelines and expert consensus have recently been published [ ] [ ] [ ] providing an overview of "safe" working protocols, it appears that we are evolving every day in our practices with respect to "what works" and "what does not." our article aims to bridge the gap between guidelines and in-clinic experiences to provide a set of best practices to follow for aesthetic procedures after reopening our practices. an invitation to participate in the consensus group meeting along with a formulated questionnaire was sent by email by one of the moderators (rk) to seven experts in the field of dermatology and aesthetics, having experience in the working and administration of single or multiple clinics, from different parts of india, in order to avoid a regional bias. the questionnaire focused on scope of the guidelines, the preparation before resuming practice, triaging/categorization patients, ppe and general sop's and specialized sop's for aesthetic procedures. (table s ) while analyzing the questionnaire, the response to general sop's (cleaning, sanitization etc.) and triaging achieved over a % concordance in response the final meeting focussed on ppe and specialized sop's for aesthetic procedures. an online meeting of the group members was held on may , using zoom online app. the virtual meeting was led by the moderators, via a prepared slide deck. further, the meeting was recorded for final analysis and simultaneous notes were taken. to encourage equal participation the moderators used an open questioning style, however, few of the questions were closed ended (yes/no) to arrive at a consensus. analysis of the detailed discussion was divided into the following sections to provide recommendations for optimal and safe "in clinic" functioning for the physician. seven out of the eight experts had reopened their clinics after overcoming initial apprehensions. all the participants agreed that they were functioning at limited capacity in terms of number of staff visiting the clinic, number of days and/or hours at work. those with more than one center started reopening with a single/flagship center and slowly imposed similar guidelines after weeks of work in other centers. all participants agreed that a "dry run" prior to reopening is crucial for staff training and creating awareness and educating oneself and the staff, as the margin for error learning on the job would be minimal. moreover, constant updating of oneself and the staff resulted in smoother functioning and execution of new sop's. the experts agreed upon the fact that the patients have been understanding and appreciative of clinic efforts and responsive in terms of cooperating with protocols. all experts agreed to doing and encouraging tele consultation. while certain modes of viral transmission have been suggested, in a statement issued by the who precautions have been laid out for droplet transmission, contact, and airborne precautions for aerosol generating procedures. an aerosol is defined as a suspension of fine solid particles or liquid droplets in air or another gas, which maybe produced by either natural or anthropogenic phenomena. the coronavirus has the potential to become "aerosolized" by certain procedures leading to a possible airborne transmission. the exact definition of "aerosol generating procedures" (agp's) in the theme of aesthetic procedures seems unclear with no clear evidence regarding the same. although, it is clear that an aerosol generating procedure increases the risk of viral transmission in healthcare workers (hcw) and should only be undertaken when necessary, this is primarily suggested for respiratory and surgical procedures generating aerosols. the different types of aerosol comprise: . respiratory aerosol: respiratory or upper airway secretions, containing a higher viral content and a greater risk of viral transmission. . surgical or nonrespiratory aerosol: aerosolisation of blood and tissue fluids leading to relatively lower risk of viral transmission. the who defines "droplets" as > μm in diameter and "airborne particles" as < μm in diameter. droplet transmission is the result of larger particles, which have the tendency to settle on the ground and on nearby surfaces. this type of transmission occurs due to proximity of the hcw with the patient. in contrast, the occurrence of airborne transmission is due to smaller particles, which maybe suspended in the air for long periods and can infect people distant from the source (eg, agp's)ppe consists of protective apparel and/or equipment designed for providing protection against infectious agents to hcw's and their patients. the appropriate use of ppe is crucial, and the decision regarding the ppe to be used is based on the setting between the hcw and the patient, the procedure being carried out, the secretions produced. the panel recommendations for ppe are discussed below. globally, recommendations for protection of hcw's against covid- for nonaerosol-generating procedures (nonagp's) are conflicting. [ ] [ ] [ ] [ ] with the barrage of masks available, choosing the right one becomes crucial. the expert panels recommendation and the differing types of masks have been elaborated ( table ). the panel felt that while the role of the staff and the type of procedure would be key factors defining the type of mask used, the space in the clinic would also be a defining factor, as certain clinics would be smaller wherein maintaining an "ideal social distance" ( ft apart/ arm's length) maybe a challenge. in such scenarios, an n respirator maybe used by the support staff as well ( figure ). use of n facial facepiece respirator (ffr) . all the experts unanimously agreed upon the use of n respirators for themselves, particularly when involved in non-agp's close contact procedures or agp's. . beard hair:it is recommended for one to be clean shaven, however, beard styles such as soul patch, side whiskers, pencil, toothbrush, lampshade, zorro, zappa, walrus, painter's brush, chevron, and handlebar maybe considered. the recommendations are to make sure that the n ffris well fitted on face. . use of n ffr in sikhs: the religious beliefs in the sikh population, leads to an inability to trim or cut the beard hair leading to difficulty in achieving a tight fit of the respirator. in such cases, either a powered air-purifying respirators (papr) maybe used, which provides facial coverage despite the facial hair or any facial irregularity. paprs are more expensive than n ffr's. else, the individual in question can make use of a "cotton cloth" or "thatha" around the beard and tie a knot on the top of the turban. this allows for coverage and a smooth surface over the facial hair for the respirator to sit on and achieve a tight fit. • use of paper bags: while only considered single use masks, all panel members agreed to reuse of their masks. a -mask set maybe used by each individual, along with four brown paper, breathable bags, which are marked to . after use of first mask, it should be placed in the paper bag and allowed to dry for days. it should be reused on day . the masks maybe used sequentially in such a manner and once all masks have been used five times, they should be discarded. use of a disposable, surgical three ply mask/face shield on top of the respirator will further prevent it's contamination. this was being followed by three of the panelists and has been suggested as an additional safe practice. the physiological burden (heart rate, oxygen saturation, tidal volume, respiratory rate, etc.) of using a surgical mask over an n respirator has been a matter of concern and while using it for short durations appears to have no significant physiological burden, studies with usage over longer periods are suggested in order to consider this as a routine practice or recommendation in daily practice. • uvc ( nm) at the appropriate dosing or vaporous hydrogen peroxide if available can be used for decontamination of the n mask. • negative seal check: on inspiration face piece should collapse. • fogging: while minimal fogging of glasses is inevitable, due to water vapor released via the edge of the mask, it may suggest that the ffr may not be air tight. it is recommended to squeeze the metal frame on the upper edge of the mask in such cases and re-assess the fit of the mask. following strict hand hygiene along with use of nonpowdered, latex gloves are adequate for examination of patients and/or consultation room. the recommendations for hand hygiene include use of an alcohol-based hand sanitizer ( % ethanol or % isopropanol) or hand wash for at least s with soap and water. • nitrile gloves are preferable over, latex gloves in the procedure rooms, as they are resistant to damage by chemicals or disinfectants, and are hypoallergenic. • housekeeping staff may use nitrile or rubber gloves which cover above the wrists. • while donning of gloves one must make sure the gloves extend to cover above the wrist of the isolation gown. a. face shield and goggles: • the panel agreed upon the use of a face shield as a routine measure in current circumstances, during all consultations and procedures as it not only provides protection to the mucosal surfaces but also prevents inadvertent touch to the face, eyes, nose or mouth with a contaminated hand. • face shield and/or goggles are a must in agp's. • use of face shield/goggles may result in fogging at times due to expired air escaping from the mask, in such circumstances one may reassess the fit of the mask or seek the use of well fitted antifogging goggles ( figure ). b. coverall or gowns • disposable, below knee, spunbondmeltblownspunbond (sms) material, breathable gowns are adequate for consulting and examination. an autoclavable, below knee, surgical cloth gown for routine consultations was suggested by three of the experts, however, the panel did not arrive at a consensus for this. practice. if a coverall is used, one coverall should be used per patient and these maybe reserved for agp's. one may use a - gsm, coverall, as extrapolated from data during the ebola outbreak. • a plastic apron maybe used over the gown, in procedures involving body fluid splatter or splash. • the panel agreed upon the use of head caps during "close contact" procedures and these should be worn by the patient and the doctor/therapist. if wearing a coverall, that itself would provide head coverage, else a surgical head cap should be used. • experts felt that that if regular cleaning and sanitation of the premises is being carried out, the use of shoe covers is not mandatory. • if shoe covers are used they should be made ideally be impermeable, for example, plastic • one of the experts on the panel suggested the use of washable rubber slippers for patients and staff in place of shoe covers. • the common principles regarding use of ppe, including hand hygiene prior donning and during doffing of ppe, protocols of donning/doffing and correct disposal should be repeatedly discussed with the clinic staff. • a room with a mirror is ideal for donning and doffing of ppe.developing a "buddy system" may help, that is, a team member who may observe the donning and doffing process. and/or use of zinc ointment before donning and after doffing the ppe. . make sure the ffr is "well fit" and not "overtight". the lips touching the front of the mask is suggestive of a tight fit and can become uncomfortable for the user. a mix of "natural" and "mechanical ventilation" is ideal for a clinical premises, which allows the air to flow from areas where there is a suspected source, towards the areas free of susceptible individuals. the use of laser and ebd's, requiring contact of the skin with the laser tip, particularly need to be handled with caution. the cases for laser procedures maybe divided into low, medium or high risk (table ). further, certain points regarding the procedures maybe taken into consideration. certain laser systems, (ablative co , erbium yag) lead to "plume" the panel categorized the risk involved with injectable procedures in the following manner: (table ) a. low risk: the mask of the patient can remain on. b. medium risk: the mask of the patient is off. c. high risk: the mask of the patient is off and the procedure involves the oral or nasal mucosa. certain procedures for example, periorbital enhancement even though carried out on the upper face, are often done with cannulas and ideally require the mask be off, so that the injector can carry out the procedure comfortably and look out for vascular events. further, a tight fitting mask during and postprocedure may lead to external compression and/or make evaluation of a unexpected vascular event challenging. the risk categorization for chemical peels is below: • low risk: body peels, spot peels on face with mask, peels for nails and periorbital area. • low risk: prp therapy for scalp and body areas, mesotherapy for scalp and body (stretch marks) • moderate risk: prp and mesotherapy for face numerous other procedures carried out in an aesthetic clinic have been categorized below (table ). the above recommendations do not necessarily signify a "cook book" approach but are learnings over the past few months in an active clinical aesthetic practice during the ongoing pandemic. while one must adapt fast to the "new norms", the real challenge would lie in the strength of the practitioner to balance one's own and our staffs mental health, to attain equilibrium of financial setbacks with concerns over self, staff, and patient safety, and to conduct practices in a just manner. the well-known adage to "lead as an example" is the best reinforcer of safe practices and general wellbeing. the authors declare no conflict of interest. covid- and economy

potential receptor for sars-cov- . this protein interacts with several extracellular and intracellular proteins like cyclophilins a and b and matrix metallopeptidases (mmps). recent studies have reported that the spike protein of sars-cov- attaches to host cells via angiotensin-converting enzyme- (ace- ) and cd receptors. cd is expressed in different tissues such as epithelia, as well as lymphoid and myeloid cells. notably, cd plays an essential role in the pathogenesis of several diseases including certain infectious/inflammatory conditions and cancers. in fact, recent studies have suggested cd as a novel tumor marker in the early diagnosis of some cancers like head and neck squamous cell carcinoma and hepatocellular carcinoma. in melanoma, cd overexpression fulfills important roles in the proliferation, metastasis, invasiveness, and angiogenesis of malignant melanoma cells. it has been shown that melanoma cell proliferation, migration, and metastasis this article is

in order to investigate whether these searching terms objective for other communities or not. although the first case of covid- in italy appeared earlier than turkey, similar measures such as the

during the covid- pandemic (table ) . after the covid- pandemic, the number of patients who request dermatology outpatient clinic visits was decreased in many countries because of stay at home policies in order to deal with the global pandemic. , , thus, certain diseases that may be increased in number after the covid- pandemic remained concealed. dermatology outpatient clinics represent only the tip of the iceberg during the covid- pandemic days. therefore, it can be expected that using the internet quite increased by the public in order to access their health information during the current pandemic. the investigation of the public trends may give some clues on the frequency of certain diseases in the covid- pandemic. in this context, according to this study, interestingly, relative changes in search terms were similar between turkey and italy after the covid- pandemic. we found that "acne", "hair loss", and "eczema" search terms increased after the covid- outbreak both in turkey and italy. the relative change in these terms was more prominent in april and may . as compared to each other, the most common search term among general dermatologic diseases was "eczema" followed by "hair loss" in turkey, whereas "acne" was the most common disease followed by "eczema" in italy. there are some points that should be addressed in this regard. the enhanced preventive

excluded in our patients on the basis of time of onset of the lesions, non-specific findings on nerve conduction velocity and resolution of the symptoms following recovery from the disease. one of our patients presented with symptoms of "erythromelalgia", and this could be attributed to microvascular thrombotic injury. complement associated microvascular injury and thrombosis have been already implicated in the pathophysiology of severe covid- infection, and the development of "erythromelalgia" like symptoms could be attributed to a similar mechanism. therefore, the temporal association, complaints of the peculiar neurological sensation followed by development of erythema and swelling in our patients, supports the probable association of the cutaneous manifestations, with covid- . the patients had been advised symptomatic treatment, and the signs and symptoms disappeared following recovery from the disease. in a recent study published by recalcati et al. from italy; commonest signs

by varicella zoster that remains dormant in the dorsal root ganglia of cutaneous nerves following a primary chicken pox infection. in this report we describe two cases covid infection who first presented with herpes zoster. we are here by suggesting that the clinical presentation of hz at the time of the current pandemic even in patients giving mild or no suggestive history of upper respiratory symptoms should be considered as an alarming sign for a recent subclinical sars cov infection. this article is protected by copyright. all rights reserved. most patients with covid- exhibit mild to moderate symptoms, but approximately % of the cases progress to severe pneumonia and about % eventually develop acute respiratory distress syndrome (ards), septic shock and/or multiple organ failure ( , ) . finding tools for recognition of asymptomatic carriers would be very helpful in the management of this outbreak. a wide array of skin manifestations in covid infection were reported including macuulopapular eruptions, morbilliform rashes, urticaria, chicken-pox like lesions, livedo reticularis, covid toe, erythema multiforme and pitryasis rosea and several other patterns ( ). we present two cases of clinically diagnosed herpes zoster infection attending two different clinics, both patients' showed no or mild symptoms of covid infection and denied any history of contact with known or suspected covid cases. case a -year-old man presented with painful blisters on the right side of his right loin. the pain was severe, continuous and stabbing in nature. he gave a history of initial stabbing pain followed by onset of blisters. the blisters were initially small and few in number; they later increased in number covering the entire right half of the loin with a watery discharge that turned hemorrhagic. fig no relevant medical history was given except for rare bouts of untreated hypertension and hypercholesterolemia. the area surrounding the vesicular eruption was flared and tender to touch. the patient was discharged and prescribed valaciclovir g twice daily for week, acyclovir cream and paracetamol for his fever. two days following the presentation, the patient developed a heavy cough, sore throat, dyspnea and fever that required hospitalization. several studies agreed that covid infection is associated mostly with reduction in lymphocytes, monocytes and eosinophils ( - ) with drastically reduced numbers of cd + t cells, cd + t cells, b cells and natural killer (nk) cells ( ) . in addition the follow-up of the dynamic changes of the lymphocyte counts along the course of the disease showed that the non-survivors developed more severe lymphopenia over time. white blood cell counts and neutrophil counts were higher in non-survivors than found in survivors and also the lymphocyte counts continued to decrease until death occurred in non-surviving patients ( ). this article is protected by copyright. all rights

pandemic era: a narrative review date: - - journal: dermatol ther doi: . /dth. sha: doc_id: cord_uid: cvtqj w pemphigus vulgaris (pv), an autoimmune blistering disease is treated with immunosuppressive medications. as the immunosuppressive effect of rituximab, the first‐line therapy of pv, lasts more than months, many concerns have raised due to the ongoing novel coronavirus disease (covid‐ ) pandemic. with this background, our objective was to review the currently available literature as well as important websites for the evidence related to rituximab, pv and covid‐ , adverse effects associated with drugs, and relevant guidelines. “pubmed” and “google scholar” database were systematically searched for retrieving all articles related to anti‐cd therapy in pemphigus vulgaris and covid‐ published up to july . a total of seven clinical studies are performed with anti‐cd therapy in covid‐ , three of which are performed on pemphigus patients, and have shown concerns employing rituximab in patients with covid‐ . evidence for treating pv patients with rituximab in covid‐ pandemic is limited. until sufficient evidence or guideline for pemphigus and covid‐ treatment is available, we advocate caution commencing rituximab in patients with pemphigus, due to the reported adverse outcomes. pemphigus, an autoimmune disease with yearly incidence of one to seven cases every million in european and american population has subtypes, that is, pemphigus vulgaris (pv) and pemphigus foliaceus with contribution of % and % patients, respectively. pv is potentially fatal disease with blisters involving mucocutaneous surfaces such as skin and oral cavity. intraepidermal vesicles with acantholysis and intact basal layer are the characteristics of pv lesions. autoantibodies are targeted against desmosomal cadherins desmoglein- and desmoglein- antigens, which play role as adhesive factors between nearby keratinocytes. the result is loss of adhesion between cells and development of blisters. , , studies have shown that blood serum level of anti-desmoglein igg is associated with disease activity in pv patients. , mortality rate in patients with pemphigus has decreased from % to %, by treating with corticosteroids. about %- % of patients experience complete remission by long-term systemic corticosteroids administered in the high-dose (prednisolone in the dose of . mg or more per kg every day). current pv treatment includes corticosteroids given in high doses and immunosuppressive drugs. consequences of such combination therapy can include long standing suppression of immunity, and outcomes associated with this condition are the most common cause of mortality in pv. patients not responding to the mentioned combination therapy, or who present with severe side effects, are given intravenous immune globulin (ivig). this is a successful method, and its monotherapy can be associated with long-term remission. , removing the autoantibodies from blood circulation can be considered as a therapeutic approach, due to their pathogenic role in pemphigus. a trial reported significant reduction in the anti-desmoglein antibodies in serum with single cycle of high-dose intravenous immunoglobulin ( g/kg) and resulted in satisfying clinical outcome. rituximab, a mouse/human monoclonal antibody (igg -κ) targets the cd antigens presenting on b lymphocytes surface. it clears the blood circulation out of cd expressing b lymphocytes by binding to cd antigens. most patients taking rituximab experience lymphopenia, which lasts about months. complete recovery of b lymphocytes in peripheral blood circulation is usually observed nine to months after the treatment course, when no cd antigen is expressed on hematopoietic stem cells. , for the first time in , thousands of pv and pemphigus foliaceus patients were treated with rituximab worldwide. in , the european academy of dermatology and venereology guideline suggested rituximab as a third-line treatment. , , rituximab decreases blood serum level of anti-desmoglein autoantibodies rapidly, which results healing of pemphigus lesions after few weeks of infusion, and complete remission is achieved after - months. , experimental studies have shown that anti-cd therapy is the most important advance method for treating patients with pemphigus, after the advent of corticosteroids. old age and comorbidities (eg, hypertension, diabetes, obesity, smoking, and cardiovascular and lung disease) are considered as risk factors for the novel coronavirus disease (covid- ). immunocompromised patients, for example, those with pv receiving immunosuppressive disease-modifying therapies can also have increased risk of severe infection with coronavirus. as a result, any physicians and patients are concerned about the ongoing situation, particularly patients taking immunosuppressive drugs, as well as pemphigus patients. in this article, we reviewed the literature focusing on the treatment, management, and subsequent consequences of rituximab as a treatment for pv in the present covid- pandemic era. we performed a computer-assisted search of "pubmed" and "google scholar" databases up to july using the keywords "anti-cd therapy," "pemphigus vulgaris," and "covid- ." we also searched other related keywords such as coronavirus, rituximab, immunocompromised, immunosuppressive drugs, pathogenesis, clinical presentations, treatment, and outcome. experimental studies have proven that rituximab, monoclonal antibody has capability of binding to cd antigen and removing b lymphocytes expressing cd from blood. according to the literature, it is considered as the first-line treatment for patients with pv based on the efficacy and safety profile. due to the immunosuppressive role of rituximab, which could last at least months, some cautions needs to be exercised when employing rituximab for treating patients with pv, especially during ongoing covid- era. patients with autoimmune bullous diseases (aibds) must never drop out their immunomodulating therapy. unjustified withdrawal can result in uncontrolled disease activity and lead to increased risk of morbidity and mortality. risk of opportunistic infections (including viral infections) is much more in patients with aibds receiving immunosuppressive therapies, than the healthy population. infections can activate the bullous activity. it is important to note that pemphigus as well as pemphigoid are associated with amplified risk of mortality due to pneumonia. , athough some studies may have reported that risk of infections is not different between aibd patients treated with rituximab or high dose corticosteroids, coronavirus can target the central nervous system (cns), which is protected by humoral immunity. , although a theory proposed the expression of ace (receptor for corona virus on the surface of host cell) in the brain, the exact mechanism of cns involvement in covid- is still unknown. according to the mentioned significant role of humoral immunity in corona virus infection, treating pv patients with rituximab is potentially risky. given the fact, patients with pv who are treated with rituximab should be monitored closely, concurrent corticosteroids regimen should be tapered, and risk of taking rituximab must be weighed precisely, to minimize the risk of infections. , analysis of outcome of patients with known autoimmune and auto-inflammatory diseases and having covid- showed that outcomes may differ because of the immunomodulatory therapeutic regimen. it suggested that patients treated with hydroxychloroquine, tnfα antagonists, anakinra, or tocilizumab, or secukinumab seems to have the worst outcomes, according to the rate of intensive care unit (icu) admissions. high amount of il- , a strong factor related to mortality in covid- patients, is seen in patients given rituximab and secukinumab, that can be due to the failure of rituximab and secukinumab to modulate il- . , according to a report of patients with granulomatosis and polyangiitis presenting with severe covid- infection, shortly after taking rituximab, suggested the drug may not be as safe as usually considered. monti et al proposed that rituximab should be considered with caution during the covid- pandemic. also, guilpain et al reported three systemic sclerosis (ssc) patients treating with rituximab, which resulted to late clinical worsening to severe pneumonia due to the covid- infection. while searching data about anti-cd treatments in covid- pandemic era, we found some studies regarding the efficacy and harmlessness of anti-cd drugs for treating multiple sclerosis (ms) patients during covid- . although prevalence of infections in ms patients treated with ocrelizuma, were slightly more common than the comparator arms, , but the data indicates that anti-cd therapies are may be safe to initiate and re-dose in ms patients during the covid- period. rituximab is a monoclonal antibody which irreversibly affect cd -expressing b lymphocytes and remove them from blood circulation. it is the only us-fda approved agent for moderate to severe pemphigus. although it is a the first-line treatment for pv patients, some concerns have been made due to the immunosuppression in the ongoing covid- pandemic. infectious events (ie) after treatment by rituximab can be extremely severe, particularly in patients immunocompromised by several drugs. on the other hand, therapeutic regimen of pemphigus patients almost contains corticosteroid dose with other immunosuppressives (such as anti-cd agents). . besides, cns is almost only protected by humoral immunity. there are evidences showing that cns can be involved by coronavirus. based on the available literature, we believe that reconsideration must be applied for therapeutic principles of treatment of patients with pemphigus receiving rituximab, during the present pandemic. we propose that it is better to taper corticosteroids, and temporarily discontinue rituximab from the therapeutic regimen of patients with pemphigus, or reduction in the doses can be considered. we can consider intravenous immunoglobulin as a replacement for rituximab, which is beneficial for both pemphigus and covid- . also we can use hydroxychloroquine instead of rituximab, which is used to treat elderly or pregnant pemphigus patients. although anecdotal evidence in pemphigus and covid- , plasmapheresis could also be considered. efficacy convalescent plasma in pemphigus is unknown. overall, care should be taken while starting immunomodulatory drugs associated with a definitive risk of severe infection especially rituximab or some other nonbiologics such as tnf-alpha inhibitors. emerging selective agents for example, a new oral bruton tyrosine kinase inhibitor which works via reversible covalent binding may offer some advantages for pemphigus. immunomodulatory effect of this agent is self-limited. access to this agent can be very useful, particularly in the present extraordinary circumstances. additionally, ofatumumab a human monoclonal cd antibody has short duration of action than rituximab. despite early promise in pemphigus treatment, a phase clinical trial was prematurely stopped because of changing priorities of the sponsor. tocilizumab, an antiinterleukin humanized monoclonal antibody, proposed for treatment in inflammatory phase of covid- has anecdotally reported to be of use in pemphigus. another approach is extended-interval dosing of rituximab, in cases we can-not cut off rituximab. anti-cd therapies used to treat pemphigus patients, including rituximab, are typically given every weeks. the b-cell depletion effect usually lasts much beyond months (the scheduled dosing interval). , in the ongoing covid- pandemic, dosing at longer interval should be considered, particularly in b cell depleted patients at the time of the next scheduled dose or those with reduced level of serum igg. the mentioned approaches reduce hospital visits of patients, which has a great effect on reducing the exposure of patients to coronavirus. although, all of the above is suggested as a novel beneficial therapeutic principle for pemphigus patients in the covid- pandemic, the final decision should be made by the relating physician, taking into account the severity of the disease, side effects of the drugs, risk of continuing the previous treatments and the consequences of changing the patient's treatment regimen. although evidence for treating pv patients with rituximab in covid- pandemic is limited, and outcomes of ms patients taking rituximab was controversial, until sufficient evidence as a guideline for pemphigus and covid- treatment is available, we advocate caution commencing rituximab for pemphigus patients and adherence to basic principles of infection control and decreasing drug induced immunosuppression as possible. the authors declare no

[ ] [ ] [ ] in dire times like this, other specialists including dermatologists have stepped up and volunteered their services to help ease the burden and share the medical workload. dermatologists across the globe have been screening outpatients, manning isolation wards, tending to non-dermatology wards, assisting in stepdown intensive care units, and so on. , some dermatology departments have been converted to quarantine units, with the same manpower detailed for duties. in short, all efforts are being made to "flatten the curve" of new covid- cases. the flipside lies in the fact that not all dermatologists feel competent enough to discharge duties of the said nature. in most countries including switzerland, dermatology residency entails five years of training including ward rounds, inpatient care, outpatient consultation, mandatory dissertations, research projects, case presentations, scientific writing and specialists exams -but all pertinent to the subject. thereafter, we diverge into the various sub-specialties of dermatology. the ramification of this article is protected by copyright. all rights reserved. this is a relative dissociation from general, internal and emergency medicine per se. this may be particularly palpable in solitary private practitioners, dermatologists working exclusively in specialty clinics and private hospital employees.. some countries, such as australia and new zealand, have barely any dermatologists in their public hospitals. at least in teaching hospitals, there exists an interdisciplinary integration with frequent clinical meetings, interdepartmental seminars and house calls, wherein, there is significant exposure to internal medicine and its machinery. even in the armed forces teaching institutes, serving as a general practitioner is mandatory before dermatology residency to become trained in, internal medicine and infectious diseases. in brief, internal medicine rotations should be made mandatory for dermatologists as this foundation may of use not only for our professional routine but also for exceptional healthcare crisis such as covid- . being capable of basic interdisciplinary multitasking ready to be deployed at sudden times of need could certainly help to correct misconceptions of dermatologists being rather cosmetologists than competent physicians. this assumption may reinforced with the skinserious campaign launched by the american academy of dermatology which reemphasizes the integral role of dermatologists in health care. this article is protected by copyright. all rights reserved. priorities for global health community in covid- pandemic utility and risk of dermatologic medications during the covid- pandemic safety measures in dermatology help minimize spread of covid- covid- : challenges and opportunities for dermatology response dermatology residents and the care of covid- patients dermatology staff participate in fight against covid- in china evaluating dermatology residency program websites key: cord- - pi wcv authors: conforti, claudio;

[ ] [ ] [ ] as such, we propose that the lower rate of severe covid- infection in female patients may be attributed to lower ar expression. , additional evidence to the possible implication of androgens in covid- infection severity is found in the molecular mechanism required for sars-cov- infectivity. sars-cov- is part of the coronavirus family of viruses including sars-cov- and mers-cov. coronavirus predominantly infects type ii pneumocytes in the human lung. previously, it was demonstrated that sars-cov- cell entry depends on priming of a viral spike surface protein by transmembrane protease serine (tmprss ) present in the host. , in type ii pneumocytes, tmprss expression is associated with an increase in ar expression, specifically connecting ar expression to sars-cov- , due to ar-regulated tmprss gene promoter (figure ). moreover, angiotensin-converting enzyme (ace ) has been recognized as the attachment molecule to the viral spike surface protein, thus termed the "receptor of sars-cov- ". interestingly, ace has been shown to have reduced activity by the decrease of androgen hormones (experimental orchidectomy), possibly by decreased expression of ace . to test this hypothesis, it would be informative to study the epidemiology of covid- patients that are predisposed to either lower or higher ar expression, such as, males suffering from androgenetic alopecia, benign prostatic hyperplasia, or women suffering from polycystic ovary syndrome. in addition, analyzing ethnic variation in ar expression may predict covid- ethnic mortality differences. additionally, the activation of ar can be reduced by several classes of drugs including ar antagonists, androgen synthesis inhibitors, and antigonadotropins. for example, the fda-approved -alpha reductase inhibitor finasteride demonstrated reduction of activation of ar in multiple tissues. other potential drugs that could be studied include: cyproterone acetate, megestrol acetate, chlormadinone acetate, spironolactone, medrogestone, oxendolone, osaterone, bifluranol acetate, flutamide, bicalutamide, nilutamide, topilutamide, enzalutamide, apalutamide, dienogest, drospirenone, medrogestone, nomegestrol acetate, promegestone, trimegestone, ketoconazole, abiraterone acetate, seviteronel, aminoglutethimide, dutasteride, epristeride, alfaestradiol, and isotretinoin. taken together, the evidence warrants further studies to elucidate the role (if any) of the ar on the severity of covid- infection. f i g u r e tmprss gene transcription promoter site requires an activated androgen receptor, with androgens such as testosterone. dihydrotestosterone (dht) a potent androgen receptor activator and is intracellularly produced in particular cells of tissues such as prostate, hair, and liver that express -alpha-reductases, the targeted enzyme for drugs such as dutasteride and finasteride ( -alphareductase inhibitors) clinical characteristics of coronavirus disease in china sex differences in fetal lung maturation dihydrotestosterone inhibits fetal rabbit pulmonary surfactant production evidence for a protective role of pulmonary surfactant protein d (sp-d) against influenza a viruses androgen receptors influence the production of pulmonary surfactant in the testicular feminization mouse fetus regulation of brain androgen receptor immunoreactivity by androgen in prepubertal male ferrets changes in amount and intracellular distribution of androgen receptor in human foreskin as a function of age intrinsic versus extrinsic aging: a histopathological, morphometric and immunohistochemical study of estrogen receptor β and androgen receptor different levels of alpha-reductase type i and ii, aromatase, and androgen receptor in hair follicles of women and men with androgenetic alopecia androgen receptor expression is greater in macrophages from male than from female donors. a sex difference with implications for atherogenesis immunohistochemical, in situ hybridization, and ultrastructural localization of sars-associated coronavirus in lung of a fatal case of severe acute respiratory syndrome in taiwan sars-cov- cell entry depends on ace and tmprss and is blocked by a clinically proven protease inhibitor evidence that tmprss activates the severe acute respiratory syndrome coronavirus spike protein for membrane fusion and reduces viral control by the humoral immune response androgen receptor and androgen-dependent gene expression in lung prostate-localized and androgen-regulated expression of the membranebound serine protease tmprss predicting the angiotensin converting enzyme (ace ) utilizing capability as the receptor of sars-cov- sex hormones promote opposite effects on ace and ace activity, hypertrophy and cardiac contractility in spontaneously hypertensive rats key: cord- -br cr kj authors: arora, gulhima;

[ ] [ ] [ ] [ ] this aspect is of particular interest since it may affect the patients' compliance leading to treatment discontinuation or autonomous modifications. although biologics have revolutionized the management of chronic dermatological disorders, their interplay between disease, disease activity, and its pharmacological treatment is complex and multifaceted, and sometimes drug-related side effects may occur (ie, airway infections). side effects are also capable to detriment dermatologist-patients relationship leading to a decreased compliance. furthermore, also inside the dermatological field the attitude towards biologics are discordant , due to the dearth of available data. in these historical and scientific context of uncertainty, in which hospitals are overwhelmed by covid- emergency and at the same time are struggled also by the normal routine (acute patients and chronic ones), we decided to perform a study to assess how covid- impacts patients under biologics to optimize our daily approach. the protocol study of the present investigation was in-depth reviewed, respected the ethical principles of seventh helsinki declaration and received full ethical clearance by the involved institutions. all patients signed a written consent form. this cross-sectional, questionnaire-based survey was performed in sidemast.org/blog/coronavirus). patients scheduled for these days were consecutively enrolled if they met the eligible criteria. patients were enrolled in the present study if meeting the following inclusion criteria: (a) aged ≥ years, (b) diagnosis of plaque psoriasis, atopic dermatitis or hidradenitis suppurativa performed by two independent board-certified dermatologists lasting more than years ago, (c) with a severity. • in psoriatic patients: psoriasis area severity index (pasi) ≥ and or disease activity index for psoriatic arthritis" (dapsa) remarkably, in these departments patients undergoing a biological therapy were affecting only by psoriasis (pso), or atopic dermatitis (ad) or hidradenitis suppurativa (hs). after verifying medical history and demographics already recorded in the database, two board-certified, independent dermatologists clinically assessed the enrolled patients collecting the appropriate severity scores in compliance with the italian guidelines. [ ] [ ] [ ] [ ] [ ] ad patients were evaluated using dermatologic quality of life score (dlqi) , and eczema area and severity index (easi). pso patients were evaluated using dlqi, pasi and dapsa (if psoriatic arthritis was co-diagnosed), whilst hs patients underwent dlqi, hurley score, ihs and autoinflammatory disease damage index (addi). before commencing any statistical analyses, data were visually inspected for capturing potential outliers. descriptive statistics was performed, by expressing values as means ± sds. scores were also assessed in terms of kurtosis and skewness. regression analyses were carried out to shed light on the determinants of the knowledge score. scores for each domain and for the overall questionnaire are reported in table . noteworthy, no differences among the disease groups remarkably, ( . %) patients perceived that their chronic dermatological disease expose them to a moderate-to-severe risk to contract sars-cov , whereas . % and . % regard it as low or null. despite only . % thought that biologics expose them to a moderate to severe risk to contract sars-cov , . % and . % of the whole patients declared that they have assessed the possibility to discontinue or modify the dosage of the current biologic therapy, respectively. at the multivariate regression analysis, knowledge regarding the virus epidemiology was found to correlate with male gender (coefficient globally male patients (coefficient regression . , p = . ) with higher scholarity level (coefficient regression . , p = . ) displayed higher knowledge of covid- . further details are reported in table . table .

respiratory epithelium, thus it may cause respiratory symptoms of different severity spacing from mild cough to death in . % of the cases in italy. , since covid- pathogenesis involved mainly respiratory airways, patients with respiratory comorbidities might have higher risk, but at the moment no data are present to confirm it. in literature, both psoriasis, atopic dermatitis and hidradenitis suppurativa displayed an higher risk of respiratory comorbidities; in accord with this evidence % of the interviewed patients thought that their dermatological disease could increase the sars-cov infection risk. psoriatic patients displayed a baseline airway inflammation, , that may lead to the epidemiologically proven increased risk of asthma, and chronic obstructive pulmonary disease (copd). ad theory of "atopic march" gives the pathogenetic rationale to the increased asthma risk found in atopic patients. however, the present study is not without any limitation. the major shortcoming is represented by the relatively small sample size employed. furthermore, the knowledge was limited to pre-pandemic period. it would be interesting to evaluate knowledge of dermatological patients undergoing biologics also in postpandemic period. the knowledge of covid- has a paramount importance in dermatological patients undergoing biologics and dermatologists should promote it. therapy continuation during covid- emergency seems to strictly depend on the quality of information that patients acquire. discontinuing or modifying biologic therapy expose patients to the risk of

treatment of moderate-to-severe plaque psoriasis in adult patients; it has a remarkable efficac y and safety profile and does not require particular screening or follow-up blood tests. the main criticism seems to be its slower activity, in terms of the time required for improvement, with a low rate of psoriasis area and severity index (pasi) achievement at week in clinical trials: . % of patients in esteem and % of patients in esteem . , however, in daily practice, the results were much more satisfactory from the first follow-up, even in very difficult patients. thus, a study was conducted in a real-world setting at the dermatology clinic of the university of cagliari to investigate the short-term clinical rate of response: at and weeks of treatment. the secondary endpoints were efficacy and safety for difficult-to-treat areas and challenging comorbidities. data collection was initiated in december , and two months later, the novel coronavirus disease (covid- ) outbreak emerged, spreading across italy and raising concerns about the risk of contagion and severity of covid- in immunosuppressed patients. thus, enhanced surveilla nce has been arranged in this cohort of patients, advising them to continue the treatment and contact the psoriasis service on noticing the occurrence of any symptoms. forty-eight patients were recruited after they provided informed consent to participate in the study, comprising men and women, with a mean age of years (range, - ). each patient was administered apremilast ( mg, twice a day) as monotherapy, after initial titration to minimize side effects. a wide range of different subtypes of psoriasis was included, with % of patients affected by difficult-to-treat conditions, including palmoplantar psoriasis, scalp psoriasis, and suberythrodermic forms (table ) . comorbidities with contraindications to other treatments were present in % of patients: hypertension and dysmetabolic syndrome, a history of malignancies (mammar y tumor, bladder cancer, or colorectal cancer), severe viral infections (human immunodeficiency virus, hepatitis c virus, hepatitis b virus), latent tuberculosis, psychiatric disorders, and advanced-stage liver disease. only ( %) patients were naïve to systemic therapies, while several courses of traditional systemic treatment were used in ( %) patients, and patients ( %) were required to discontinue biologics because of cancer occurrence or hepatic impairment. four patients were treated with narrow-band ultraviolet b-rays without consistent improvement ( table ) . at the -week follow-up (table ) , the primary efficacy endpoint of consistent improveme nt, quantified as at least a % reduction (fig. ) in baseline signs and symptoms (pasi ), was achieved in . % of patients ( / ), of whom ( . %) achieved pasi (fig. ) . four patients discontinued treatment because of the development of gastrointestinal adverse events (aes). the remaining patients showed a less consistent improvement, although considering the absolute pasi, there was a mean reduction from . to . , and patients were satisfied with the treatment. at the -week follow-up, patients were assumed to be taking apremilast, and another patient had discontinued taking apremilast because of treatment failure. the improvement was remarkable, with an additional patients achieving pasi . overall, % of patients achieved pasi , % achieved pasi , and % achieved pasi , with a mean absolute pasi score of . (table ). only patients ( . %) showed slight improvements in symptoms, although they were satisfied with the regimen and were determined to continue. few real-world studies have investigated the profile of apremilast; [ ] [ ] [ ] [ ] [ ] there have been no reports of efficacy after weeks of treatment, which we valued as a pasi achievement in % of patients and pasi in %. outcomes at weeks were comparable with those of previous case series, even with respect to aes and the rate of discontinuation. notably, our population was problematic in terms of comorbidities ( %), and only % of the patients were naïve to systemic treatments, including biologics. overall, only patient was considered a non-responder, and patients experienced a less remarkable but progressive improvement. the latter might represent a subset of slow responders. the achievements of pasi and pasi were unexpected after only months of treatment. the main limitation to apremilast adherence was the intensity of aes during the first weeks ( . %), leading to discontinuation in patients ( . %), and reports of mild, bearable, and healed with treatment prosecution in the remaining patients. as expected, diarrhea was the most frequent ae ( %), followed by abdominal discomfort, nausea, vomiting, and headache. unlike other reports, no weight loss or worsened psychiatric disease was observed. , none of the patients developed symptoms requiring assessment for covid- . during the observation period, the italian outpatients' services were required to suspend all visits because of the covid- pandemic outbreak in italy and the recommendation to prevent patient access to hospitals (decree of the president of the council of ministers, / / ). thus, an extraordinary effort was made to implement monitoring of and support for this cohort of patients by distance. regular telephone recalls were performed to assess whether patients had discontinued taking the drug or had contracted covid- . we followed current experts' opinion that apremilast is one of the safer options for moderate-to-severe psoriasis management due to its very specific, nonimmunosuppressive mechanism of action. recent experience in a covid- disease affected patient, who maintained apremilast treatment during the bilateral pneumonia course and recovered completely, confirms safety and compatibility with critical patient's management. exacerbation of psoriasis might have occurred as a consequence of stress burden, with the covid- pandemic conferring severely limited wellness and opportunities to relieve anxiety and mood disorders through social activities. of course, covid- , as well as certain medications currently used to control the disease, might exacerbate psoriasis, as recently reported. in this very critical period, the satisfactory speed of the therapeutic response to apremilast in a realworld setting has further strengthened patient compliance to remain safe at home and led to patients eventually enduring the initial side effects, although further studies are warranted to explore this topic. accepted article apremilast (otezla): a new oral treatment for adults with

heavy strain all over the world and in particular in the north of italy. since february st , , when the first case in italy was confirmed, an overwhelming number of sars-cov- infections were detected and hospital organizations have adapted to cope with the emergency, , . fondazione irccs policlinico san matteo, pavia, a tertiary center and teaching hospital in northern italy, became a national sars-cov- referral center. it was one of the first institutions to enact separate routes for suspected sars-cov- patients referring to the emergency department (ed) in order to isolate them from other patients, minimizing the risk of contamination of the general ed . from february nd to may rd , accesses to the ed have dramatically reduced, also for dermatological consultations [ ] [ ] [ ] . the aim of our paper was to analyze how the lockdown period has changed dermatological accesses to the ed and analyze the differences in dermatological consultations at ed between february nd to may rd , and the same period in . this article is protected by copyright. all rights reserved. we performed a retrospective review of all dermatological consultations in the ed of ircss san matteo between february nd (date of the first proven autochthonous covid- case) and may rd (date of the end of the "phase " of the lockdown). we compared these data with those from the same period in . we extracted data from medical records of all patients admitted to the ed for dermatological consultation and stored them in a database; the data was then entered in an excel spreadsheet (microsoft corporation, seattle, wa, usa). we collected demographic data and data regarding clinical diagnosis, prescription of topical or systemic therapy, need to execute a biopsy, scheduling of a follow-up visit, and administration of any kind of therapy before the consultation. diagnosis was considered definitive if clinically determined without a differential diagnosis or if confirmed by biopsy or other exams. to handle data more efficiently, all diagnoses were classified into groups (table ) . our aim was to evaluate the impact of the ongoing pandemic on the number of dermatological ed consultation, on the severity of cases presented to the ed with cutaneous symptoms, and on the diagnoses at discharge. the median number of urgent consultations per week was compared between and using mann-whitney test. all other data related to clinical presentation and management in the ed were compared between and with chi square test. we collected patients who required a dermatological consultation: patients from february nd to may rd , in the same period in . median number per week was in and . in (p= . ). in , ( . %) were females, and ( . %) were males. in , ( . %) were females, and ( . %) were males (p= .

cohort, the most frequent consultation causes were eczema and dermatitis (n= , . %) and acute infections (n= , . %). in the cohort, urticarial rashes were the most common cause of presentation (n= , . %), followed by acute eczema and infectious diseases (n= for both, . % each). the difference in relative frequencies of diagnoses between the two cohorts was statistically significant for urticarial manifestations ( . % in and . % in ) (p= . ), for scabies ( % in and . % in ) (p= . ) and for vasculopathic lesions ( . % in , . % in ) (p< . ) ( table ) . this article is protected by copyright. all

without a previous therapeutic approach (p< . ). concerning the prescription of drugs as a result of the consultation, topical therapy was prescribed in / ( . %) patients in , and in / ( . %) patients in (p= . ). systemic therapy was prescribed in / ( . %) patients in , and in / ( . %) patients in (p< . ). after the consultation, a follow-up visit was scheduled in / cases ( . %) in , and / cases ( . %) in (p= . ). a biopsy was deemed necessary in / ( . %) patients in and / ( . %) patients in (p< . ). the first finding emerging from our data was a dramatic reduction in the request for dermatological ed consultations during the covid pandemic comparing to the same period in , from patients to , with an absolute difference of - . percentage points ( table ). this result is consistent with the experience of other medical specialties in different centers [ ] [ ] [ ] [ ] [ ] and it probably reflects the fear of both being infected in the hospital environment and of violating lockdown restrictions. the data showed an increase in the proportion of patients starting medications before coming to the ed. this result confirmed our hypothesis that patients were delaying non-critical care. we noticed a rise in the frequency of biopsy requests (p< . ) and in the prescription of systemic therapy (p> . ) as a result of the consultation. this suggested an increased average complexity in the cases presenting to the ed for a skin condition in compared to the control year. in , the most common skin diseases were eczematous disorders (n= , . %), infectious diseases (n= , . %) and physical and chemical injuries to the skin (n= , . %), confirming the findings from similar studies in the past , . in , all these categories were less frequent. a few diagnostic categories showed significant difference in terms of incidence: scabies ( % vs . %, p= . ), urticarial rashes ( . % vs . %, p= . ), and vasculopathic lesions ( . % vs . %, p< . ). for scabies it is reasonable to believe that spending prolonged periods of time in close proximity with relatives might have increased the risk of contracting the infection. regarding the other two diagnostic categories, both cutaneous reactions have been described to correlate with the ongoing pandemic in the most recent literature [ ] [ ] [ ] . a limitation of this study is the small sample size for the current year; nevertheless, it reflects the reality of the recent period and it is an interesting finding by itself, despite the fact that it limits the statistical power of our analysis. another limitation lies in the unavailability of serological testing for covid- in patients presenting an atypical rash or acroischemia due to protocol restrictions on serological procedures. in conclusion, our analysis showed that the coronavirus epidemic sharply reduced the number of dermatological consultations requested in the ed. however, the complexity of cases was higher, as proven by the increased need for biopsies and systemic therapy. this may highlight how often, in normal times, the ed is used for deferable pathologies. we don't exclude that the reduction in consultations in the current period may lead to a possibly higher number of requests for dermatological visits after the lockdown, to a higher delay in diagnosis and a possible increase in morbidity and mortality . finally, the types of cutaneous disorders diagnosed in the ed was different, with a higher relative frequency of scabies, urticarial rashes and vasculopathic lesions. hospital emergency management plan during the covid- epidemic

quality of care. the fourth diagnosed case of covid- in the republic of macedonia was a dermatologist employed at the university clinic for dermatology in skopje, the only tertiary care hospital in the country. prior to being diagnosed, the doctor made direct contact with nearly all medical and non-medical personnel of the clinic. the doctor also held a previously scheduled seminar, which was attended by an additional dermatologists and dermatology residents from across the country. in the first hours following the diagnosis, rapid action was taken by government officials, and dermatologists and dermatology residents were put in home quarantine for days. only dermatologists in secondary care could resume practice in the period from in an effort to discover which of the dermatological conditions demanded immediate attention, we conducted a survey where we asked colleagues about the number and reasons for teledermatological consults. overall, dermatologists participated in the survey. ninety-one percent of respondents had received requests for consultations by patients. eighty-two percent felt that consultation via a communication application was useful for patient follow-up; however, these methods were appropriate in less than % of cases for initial consultations. the most common motives for consultations with patients were therapy follow-ups, acute exacerbations of chronic diseases, and deficiencies of certain medications due to difficulties in drug importations. most frequently, dermatology input was requested from general practitioners (gps) and pediatrics ( table ). the dermatologists, who were not subject to the home isolation measure, held outpatient examinations, in the majority of which pediatric dermatological pathology dominated ( dermatology is largely considered a nonacute, outpatientcentered specialty, with a continued reduction in dedicated dermatology beds. , our survey contributes by presenting the dermatoses, which demanded dermatological consult and which were a diagnostic and therapeutic challenge to the gps and other specialties. these included pediatric dermatoses, dermatoses of pregnancy, patients with perennial retinoid therapy, bullous dermatoses, and cases of drug eruptions, including sjs and ten. this is deducted from a -day period and concerned a population of a little over million. pediatric dermatoses constitute roughly % of both urgent visits and telecommunication consultations. the present results are broadly in line with those of previous studies, confirming the role of the dermatologist in the pediatric care. the authors declare no conflict of interest. inpatient care for dermatological patients during sars-cov- -a case report from portugal the first macedonian doyens

respiratory or gastrointestina l symptoms . dr recalcati made the first report on cutaneous manifestations in covid- nearly a month ago , and since then, several authors have also noticed covid- -associated skin rash in adults [ ] [ ] [ ] [ ] [ ] . according to them, skin symptoms may include erythematous rash, localized or widespread urticaria, chicken-pox-like lesions, vascular lesions and dengue-like rash. the trunk and the limbs are reported to be the most commonly involved sites. however, the data on covid- -associated skin disorders in children are scarce. we observed that a -year-old girl who was confined to her home in moscow due to covid- self-isolation in mid-april had a fever of . °c for consecutive days. no clinical symptoms of any bacterial or viral infection were noted except for fatigue and headache. on the second day of fever the pcr covid- test was positive. the general blood test was normal except for elevated c-reactive protein level and erythrocyte sedimentation rate. chest ct scan revealed no pulmona r y changes. the patient was most likely infected by her covid-positive mother, who is a nurse looking after many covid- patients. the treatment was unspecific and consisted of paracetamol. on the third day of illness the fever dramatically ceased and the skin rash appeared. on examination we noted purpuric eruptions and erythematous macula rashes of to mm size mainly on the upper eyelids, above the eyebrows and in temporal region (figure ). besides that, her tongue was slightly swollen and irritated with pronounced lingual papillae ( figure ). the described eruptions were asymptomatic and completely disappeared within three days without treatment. our observation confirms the idea that the covid- infectious syndrome not infrequent l y includes different types of skin rashes and as seen in this first description with a rare involveme nt of the oral mucous membranes. along with fever and fatigue, these eruptions may be considered as the only clinical manifestation of these particular covid- infections in children. this could be due to cd hyperexpression, which participates in antiviral immunity . we think it is important to monitor the skin not only in adults but also in children who can transmit this virus asymptomatically. in the case of any skin alterations we would strongly recommend that a nasopharyngeal and oropharyngeal swab is performed to confirm the possible covid- diagnosis and in this way break the chain of transmission immediately. this article is protected by copyright. all rights reserved. this

journal: dermatol ther doi: . /dth. sha: doc_id: cord_uid: iv x vap nan we have read with great interest the review article published by magnano et al. which was recently published in dermatologic therapy journal ( ) . we found it interesting to expand the discussion in this regard that may be practically helpful for the dermatologists in the era of covid pandemic. the authors pointed out the abrupt interruption of the biologics may increase the systemic inflammation, which may worsen the associated comorbidities and the prognosis of covid- . herein, we agree with the authors and add more points that would be of interest for further interpretation in this critical time. it is an area of debate whether it is advisable or not to stop biologic agents in the treatment of psoriasis during covid- pandemic. various scientific societies like american academy of dermatology (aad) and international league of dermatological societies (ilds) have issued guidelines to discontinue only in covid- positive patients but can be carefully considered on a case-by-case basis if the patient is covid- negative and with no symptoms by weighing risk vs. benefit ratio. on the other hand, many of the published case series, retrospective studies have shown that although psoriasis patients have metabolic and cardiovascular comorbidities, there is no early sign of an increased hospitalization rate amongst these patients ( , ) . moreover, the retrospective study conducted by gisondi et al. showed that there is no death due to covid- and only one hospitalization, fully recovered amongst the patients with chronic plaque psoriasis receiving a biological treatment and renal transplant recipients who were under immunosuppressive therapies ( ) . various studies have suggested to discontinue biologics only in covid- positive patients and consider biologics on case-by-case basis considering the severity of psoriasis and other co-morbidities ( , ). nuclear factor kappa b (nf-κb) is a protein transcription factor that orchestrates inflammation and other complex biological processes and is a key regulatory element in a variety of immune and inflammatory pathways, in cellular proliferation and differentiation and in apoptosis. therefore nf-κb is a crucial mediator involved in the pathogenesis of psoriasis. several antipsoriatic therapies, including tumor necrosis factor-α blockers and glucocorticoids, reduce active nf-κb levels and related down-stream elements, and other biologics currently in development, including interleukin- blockers, may also target this pathway. sars-cov- is known to be engulfed into the human cell along with the ace receptor it had combined with. this reduces the number of ace receptors on cells, leading to an increase of a polypeptide, called angiotensin ii, in the blood. angiotensin ii triggers an inflammatory pathway involving nf-κb and il- -stat particularly in nonimmune cells including endothelial cells and epithelial cells. this pathway forms a positive feedback cycle, named il- amplifier, resulting in its excessive activation and therefore the cytokine storm and ards ( ). it can be hypothesized that immunosuppressive/immunomodulator therapies using in psoriasis may suppress and/or control the "cytokine storm in covid- " and/or suppress viral activity in order to reach recovery. zumla et al. also hypothesized that blocking il- could have the potential to improve covid- 's aberrant immune response and acute respiratory distress syndromerelated mortality ( ) . moreover, previous studies have shown that biologic agents seem to have an acceptable safety profile and high effectiveness in the presence of immunocompromising such as hiv-positivity. biologic agents had a positive effect on cd and viral counts when used in combined with highly active anti-retroviral therapies in these individuals ( , ) . since, we do not have much data on biologics in psoriasis patients effecting covid- disease course, current data suggests that there is no increase morbidity/ mortality amongst these patients. to reveal the relationship with immunomodulator therapies and its effects on covid- , further case-control studies are required. covid- and acute respiratory distress syndrome: focusing on the risk of concomitant biological treatment evolution of covid- infection in psoriatic patients

flare implies systemic inflammation and immunological disruption, two recognized factors responsible for increasing susceptibility to infection in systemic polyarthritis. furthermore, an active disease entails the need of a medical reassessment, which is best to be avoided at this time, given the higher risk of contagion due to moving around and being in the hospital. diabetes and metabolic syndrome are acknowledged as associated with psa and psoriasis ; these comorbidities in the setting of a poorly controlled disease may worsen due to inflammation itself. in conclusion, before interrupting a chronic therapy, even if patients with psa have an increased risk of comorbidities and serious infections compared with patients with psoriasis, we suggest evaluating not only the infectious profile of immunosuppressants but also the underlying inflammatory nature of psoriatic disease itself, especially if severe and/or associated with articular involvement. covid- and

period. in aesthetic clinics, most procedures are provided on one to one basis by the physician or therapist. in such a scenario, guidelines detailing the infection control measures for aesthetic clinics are of particular importance. methods: an online meeting of an international group of experts in the field of aesthetic medicine, with experience in administration of an aesthetic clinic, was convened. the meeting aimed to provide a set of consensus guidelines to protect clinic staff and patients from sars‐cov‐ infection. results: consensus guidelines for ‘preferred practices' were provided for scheduling of patients, patient evaluation and triaging, and for safety precautions about the different procedures. procedures were categorized into low‐risk, moderate risk, and high‐risk based on the likelihood of transmission of sars‐cov‐ virus from the patient to the treating physician or therapist. conclusions: while not intended to be complete or exhaustive, these guidelines provide sound infection control measures for aesthetic practices. since guidelines regarding safety measures and use of ppes may vary from country to country, the local guidelines should also be followed to prevent covid‐ infection in aesthetic clinics. this article is protected by copyright. all rights reserved. the current global pandemic of the sars-cov- virus that causes covid- respiratory tract infection is likely to last for a long time. most of the countries have imposed lockdowns and introduced strict infection control measures. the reopening of society is likely to happen slowly and in a phased manner while keeping a focus on the strict infection control measures in the times ahead . appropriate precautions, up to date knowledge, and strict safety measures will be needed, not just when the lockdowns are eased in most countries but also for the entire duration of the pandemic. there is a likelihood of patient overload during this period, and staying prepared is going to be the right strategy for this situation . the safety precautions need to be extended much beyond the lockdown period in every country. no laxity in these precautions should be allowed to happen even if the curve of covid- cases flattens or falls near the baseline. while many medical practices are being run with online consultations , aesthetic clinics come in a category of medical services where most of the procedures are provided on one to one basis by a doctor/ therapist. many countries have decided to allow the opening of practices requiring one-on-one contact like dental, physiotherapy, aesthetics, provided they strictly follow the guidelines detailing the infection control measures . aesthetic clinics across the world are uncertain about the safe reopening and running of their businesses and the safety measures needed to protect their staff and patients from covid- infection. a set of consensus guidelines for 'preferred practices' in aesthetic clinics is proposed in this paper for maintaining a high level of safety for the patients coming to the clinic for treatment as well as for the doctors/ therapists performing the procedures. multiple factors could lead to transmission of covid- from a patient to the healthcare worker and vice versa, especially in an aesthetic clinic. • coughing or sneezing by patients and accompanying persons in the waiting areas . speaking loudly or deep breaths also generate aerosols. • small procedure rooms with limited or no natural ventilation • central air conditioning having a single cooling unit and multiple room vents in most aesthetic clinics, without hepa (high efficiency particulate air) filtration as present in most operating rooms • inadequate distance between the patient and treating doctor or therapist • some of the procedures could take a long time with a patient, e.g., full face ultherapy treatment, whole body laser hair reduction • repeated handling of equipment like touch screen, desktop, patient chairs by doctor/therapist and initial screening and handling of patient forms, cash, credit card by the front office staff the consensus group comprised of ten experts in the field of aesthetic medicine (one plastic surgeon, four dermatologists, and five aesthetic physicians), having experience in the working and administration of an aesthetic clinic. the participating members of the consensus group were from india, united kingdom, philippines, australia, sweden, norway, switzerland, and south africa. an online meeting of the consensus group members was held on april , , using zoom online app. following items were proposed to all the participants, and a consensus was sought to establish the 'preferred practices' guidelines during the meeting.: guidelines for patient scheduling . patient evaluation and triaging; patient categorization . guidelines for risk categorization and safety precautions for the aesthetic procedures . guidelines for staffing in the aesthetic clinics guidelines for general housekeeping in the aesthetic clinics a 'consensus reached' was considered when at least % of participants agreed on the points discussed. the consensus group decided to provide guidelines on ways to reorganize the aesthetic practices while simultaneously instituting safety measures. the government and the health authorities in each country are likely to review the infection control strategy and measures regularly, and new updates may come in the future . although cases of covid- infection can happen despite strict measures, the infection is less likely to spread in aesthetic practices with the proposed infection prevention measures. each aesthetic clinic must assess its business model and local conditions and accordingly adopt these guidelines into its daily functioning. in addition to the infection control measures listed in this article, the requirements and precautions advised by the public health authority of their respective country must be followed by the clinic patient scheduling is a critical step for the safety of patients, doctors, therapists, and clinic support staff. sticking to the guidelines for 'social distancing' will ensure safety for everyone present in the clinic. advance scheduling should be made compulsory and walk-in patients should be discouraged. the the staff should be trained to take the necessary information on the phone at the time of giving an appointment. this information should be rechecked when the patient arrives in the clinic. for unscheduled walk-ins, history taking becomes even more critical and must be done at the time of arrival. temperature recording with handheld, non-contact thermometers can be used for screening. however, they could be impractical not only due to a shortage of locally available equipment, and patients taking paracetamol to bring down the fever before arrival but also for suspected covid- patients who do not exhibit any fever . experienced staff should be deputed to take the patient's history of travel, occupation, contact, and cluster (tocc), and a declaration form along with a written informed consent document (table ) can be used to ascertain the following points . t-travel history including a detailed itinerary, transit locations and date of return o -occupation of the patient and spouse/ partner to be asked to check if it is a high-risk profession c-a history of exposure to a test positive covid- case should be asked after categorization of the patients based on tocc history and presence or absence of signs/symptoms, only patients in category a are to be taken up for an elective aesthetic procedure with due precautions, as shown in figure . the procedures performed in an aesthetic clinic (office-practice) have been categorized by the expert panel as low-risk, moderate-risk, and high-risk based on the likelihood of transmission of the sars-cov- virus from the patient to the treating physician/therapist while performing the procedure. this categorization is based on the assumption that all the patients seen in the aesthetic clinic could be asymptomatic carriers until proven otherwise. this assumption has to be made until the time covid- testing of all patients coming to the aesthetic clinics is done as part of the initial screening process. this article is protected by copyright. all rights reserved. the factors taken into account by consensus group for the risk categorization of the procedures werethe type of procedure (aerosol-generating procedure versus non-aerosol generating procedure), body part on which the procedure is being performed (face/body)and the duration of the procedure. contact with mucosa/saliva, body secretions during the procedure, minimally invasive or non-invasive nature of the procedure, and ability of the patient to be masked or not were also considered as important factors for risk categorization (table ) ( figure ). the aerosol producing procedures have the highest risk , and the long duration of a procedure also increases the risk due to longer contact time with the patient . similarly, procedures involving the middle and lower part of the face would not allow the patient to be masked at the time of the procedure, thus increasing the potential for transmission to the treating physician . based on the categorization, guidelines for ppe were also given ( table ) . the general guidelines for aesthetic procedures also included minimum conversations with the patient during the procedure, not allowing the patient attendant to be in the procedure room, and also avoid the helping staff/nurse to be in the procedure room while the procedure is being performed, if possible. try to minimize the duration of the procedure where possible to reduce exposure time . cleaning of all surfaces (procedure chair/bed, inspection lights, instrument tray/trolley) and the apparatus being used with sterilizing solution should be done after each procedure . for lhr, all the patients should be asked to shave at home and come for the procedure to reduce contact time with the staff. lip injections with soft-tissue fillers would require that patients be asked to rinse the mouth with . % hydrogen peroxide or . % povidone-iodine for minute right before the procedure . the high-risk procedures may be deferred for sometime after lockdown is lifted in the respective countries . however, when the high-risk procedures are performed, certain procedure-specific steps will be required in addition to the recommendations provided for the moderate risk procedures. for example, when aerosol-generating lasers are used, a cover with a transparent membrane such as polyvinyl clingfilm should be encouraged to reduce the splatter of the aerosolized cellular debris (like for tattoo removal with q-switched lasers), keeping in mind the potential power loss when the laser passes through the membrane . additionally, one can use plume evacuation systems with filters that remove particulates up to . micrometer, known as a ulpa ( ultra-low particulate air) filter. the consensus was that the older staff members (> years) or those with associated comorbidities like diabetes, pulmonary conditions, cardiac conditions should be given leave or given work in areas with limited patient contact . staff can be posted for shorter working hours than usual and should be called in rotation . at any given time, % to % of staff should be working at the clinic . staff must get training in donning and doffing of personal protective equipment and should be provided with appropriate ppe . the staff should be encouraged to do frequent hand washing with soap and water for at least seconds. in between, hands disinfectants can also be used. the staff should get training for phone booking, patient interviews on the phone, documentation of patient details and history, getting informed consent signed, social distancing, and hand hygiene (figure ). the following guidelines apply to sanitation and logistics for aesthetic clinics. • security desk: security guards at the entrance should wear surgical masks and maintain a two-hourly handwash protocol. the physical distance of at least m should be maintained . • sanitizing stations: special stations should be installed at clinic entrances, registration counters, and other high contact surfaces for hand sanitization (preferably contact-less) ( figure ). shoe-covers should be available for clients at the clinic entrance so that they do not bring in the fomites with their shoe soles. surgical masks and caps should also be provided at the entrance for clients who come in without wearing a mask . • seating arrangement: chairs in the waiting area should be spaced about meter apart ( figure ). in case of joined seating, distance seating could be maintained by strapping down alternate seats in the middle using ribbons or tape, making them unfit for use . • waiting area decongestion: waiting area congestion can be avoided by scheduling appointments with appropriate turnaround time between two patients. the clients could also be asked to wait in their vehicles if they arrive before the appointed time or until the doctor is ready to see them. • • non-essential material: care must be taken to remove all non-essential material like brochures, magazines, and newspapers from the offices and waiting rooms, as these could be a potential source of contamination. the staff should be trained to use electronic modes of information sharing like e-mail, this article is protected by copyright. all rights reserved. o outdoor areas: outdoor areas of the clinic would need less intense disinfection by being exposed to sunlight and air currents. however, cleaning and disinfection of frequently touched surfaces should be carried out here as well. o patient examination tables or procedure chairs: these should preferably be covered with disposable sheets, which must be discarded after each use . in case disposable sheets are not available, cotton sheets could be used and machine-washed with a regular detergent after every use. mattresses and edges of the tables and examination/procedure chairs must be sanitized using a - % alcoholbased sanitizer. if that is not available, then a % sodium hypochlorite solution could be used. • food/beverages & pantry: pantry utensils for the staff should be disposable. clients should be encouraged to carry their water bottles with them. the practice of serving tea, coffee, and other beverages should be discouraged. pantry area should be disinfected every two hours, and items like tea kettle handles and external surfaces should be disinfected after each use. during covid- pandemic, strict patient screening, social distancing, use of ppes, and taking extra precaution during 'high risk' aesthetic procedures can help in keeping patients as well the clinic staff safe from covid- infection. the patients with minimum risk of transmitting covid- , based on the risk categorization, can be taken for elective aesthetic procedures. appropriate use of ppes and other precautions can be taken by treating clinic staff as per the risk category of the aesthetic procedure. the 'preferred practices' suggested by the consensus group provide the basis for sound infection control for aesthetic clinics, though these may not be complete or exhaustive. in addition to the consensus guidelines, those provided by the health authorities in each country should also be followed. this article is protected by copyright. all rights reserved. protective equipment as per the consensus recommendations for a "low-risk" procedure. in this instance, as the treatment area is the upper face, the patient is also able to wear a face mask (contributed by wai

. /dth. sha: doc_id: cord_uid: fzj ciif nan dear editor, the current pandemic of coronavirus disease (covid- ) has raised the interest in reporting the management's experience with systemic lupus erythematosus (sle) patients under long-term treatment with immunosuppressor drugs or hydroxychloroquine (hcq). sle patients could have a higher potential risk of a severe covid- course - due to underlying immune dysregulation, the potential presence of organ damage associated with the disease and comorbidities. , indeed, infections remain a leading cause of mortality in lupus patients. recently, some authors reported the importance to maintain disease remission in lupus patients, especially in high-epidemic areas, avoiding unnecessary emergency room visits and hospitalization. therefore, it has been suggested not to discontinue current therapy in such patients. , however, no data about the management of risk infection in cutaneous lupus erythematosus (cle) during the current pandemic are present in the literature to date. our hospital is located in a high-epidemic area of lombardy: we decided to advice patients affected by sle with cutaneous manifestations and cle, to scrupulously comply with hygiene rules and protective devices use, to maintain social distancing, not to spontaneously suspend ongoing therapy and to inform the dermatologist in case of the onset of symptoms, as suggested this article is protected by copyright. all rights reserved. by the italian society of dermatologists (sidemast) and several papers. observation of these data shows that lupus patients with cutaneous manifestations could have susceptibility to covid- independently of contact with known or suspected covid- patient. in particular a higher risk factor to experience sars-cov- infection can be observed in sle patients as reported in the literature. [ ] [ ] [ ] [ ] fortunately, all the covid- suspected this article is protected by copyright. all rights reserved. patients experienced mild symptoms without severe respiratory complications. furthermore, none of our patients showed a recurrence of the underlying disease. the role of hcq on covid- is still debated and our data do not allow us to draw conclusions on the matter. therefore, we think it is important to create a communication channel with patients to reduce in-person follow-up visits, to give human support and help in managing therapies. we observed that it is essential to advise and empower le patients on activities to limit the risk of infection (hand hygiene, social distancing, use of protective devices), not only in the systemic form but also in the cutaneous form. managing cutaneous immune-mediated diseases during the covid- advice regarding covid- and use of immunomodulators, in patients with severe dermatological diseases covid- ) in a series of patients with systemic lupus erythematosus under long-term treatment with hydroxychloroquine baseline use of hydroxychloroquine in systemic lupus erythematosus does not preclude sars-cov- infection and severe covid- coronavirus disease- : implication for the care and management of patients with systemic lupus erythematosus impact of covid- pandemic on sle: beyond the risk of infection sidemast) infezione da coronavirus, vademecum per i pazienti affetti da malattie bollose e malattie autoimmuni management strategies for patients with autoimmune diseases during the covid- pandemic: a perspective from china covid- infection in a northern-italian cohort of systemic lupus erythematosus assessed by telemedicine key: cord- -j sg w authors: filippi, federica; loi, camilla; evangelista, valeria; bardazzi, federico title: covid‐ era: a chance to learn something new about monitoring psoriatic patients in biological therapy date: - - journal: dermatol ther doi: . /dth. sha: doc_id: cord_uid: j sg w nan the novel coronavirus (severe acute respiratory syndrome coronavirus: sars-cov- ) and the related disease (coronavirus disease- : covid- ) emerged in china in december and rapidly spread over the continents in a matter of months; it has dramatically changed not only our daily life, but also our daily dermatological practice , . however, these forced changes have provided us food for thought. about psoriatic patients assuming biological therapy currently refer to our psoriasis outpatient service, in sant'orsola-malpighi university hospital, bologna (italy), with an average of patients visited weekly. in the screening and monitoring of psoriatic patients, we follow the latest italian guidelines : blood tests (full blood count, creatinine and electrolytes, liver function tests, serum lipids, fasting glucose) as well as psoriasis disease severity assessment and general physical examination should be performed at baseline and periodically afterwards, on average every - months, based on clinical judgement, in particular extension of the disease (body surface area, nail involvement, critical areas localization), diagnosis of arthropatic psoriasis, comorbidities and other associated symptoms. in consequence of the covid- pandemic and in accordance with the ministerial decree of march , (gu serie generale n. - - ), all non-urgent dermatological consultations were suspended in our country, so face-to-face visits decreased markedly in favour of the now familiar this article is protected by copyright. all rights reserved. "teledermatology" , . on march , , the italian medicines agency (aifa) allowed the automatic renewal of all expiring therapeutic plans for biologic drugs for days, to prevent patients from coming to the hospital only to renew their prescription . non-urgent blood tests were also suspended, including monitoring in psoriatic patients undergoing biological therapy . this was the situation until may , , when "step " was implemented: a slow reactivation of the activities and a soft but important relaunch for italy . scheduled visits were re-established, and the retrieval of the missed follow-up visits has begun. however, blood tests are still performed only in selected cases, to avoid hospital overcrowding. considering the last months, of the approximately patients to retrieve were visited, of whom had been in biological therapy with the same drug for at least year and were considered responders. out of these patients, had self-interrupted the treatment, fearing an increased risk of infection; / responders had a slight worsening of the disease (from % to % worsening of pasi compared to the previous examination, about months earlier); in the remaining / patients, psoriasis remained well controlled (less than % worsening of pasi compared to the previous examination, about months earlier). in addition, none of the patients had been able to undergo the monitoring blood tests. so far, the disease appears to have been well-controlled in most of our patients under biological therapy, despite the undeniable period of perceived stress, income loss and outdoor activity restriction, partly thanks to the many telephone consultations we provided during the lockdown. therefore, telemedicine has proven to be a successful method in monitoring patients in "welltested" biological therapy, and it could be considered a valid option for many months to come, as this article is protected by copyright. all rights reserved. social distancing will remain the most effective safeguard, probably until the introduction of a vaccine. for the same reason, blood tests will be performed less frequently than the usual - months; we will be able to tell in a few months if this forced procrastination will have had negative consequences on the outcome of our patients. if this is not so, it could be the starting point for a further lengthening of the monitoring time of psoriatic patients considered responders to biological therapy. active implications for dermatologists in "sars-cov- era": personal experience and review of literature the covid- outbreak in italy: preventive and protective measures adopted by the dermatology unit of bologna university hospital italian guidelines on the systemic treatments of moderate-to-severe plaque psoriasis teledermatologic monitoring for chronic cutaneous autoimmune diseases with smartworking during covid- emergency in a tertiary center in italy store-and-forward teledermatology in the era of covid- : a pilot study transitional measures concerning the extension of the aifa treatment plans for the containment and management of the epidemiological emergency from covid- ulteriori disposizioni attuative del decretolegge febbraio , n. , recante misure urgenti in materia di contenimento e gestione dell'emergenza epidemiologica da covid- , applicabili sull ulteriori disposizioni attuative del decretolegge febbraio key: cord- -wtacr qj authors: almutairi, nawaf; schwartz, robert a. title: coronavirus disease‐ with dermatologic manifestations and implications: an unfolding conundrum date: -

) ( - ). the exacerbation of pre-existing skin diseases like seborrheic dermatitis, atopic dermatitis, and acne, can be anticipated ( ). most frontline health care workers will develop cutaneous lesions affecting the nasal bridge, hands, cheek, and forehead. as expected, frequent hand hygiene was associated with a higher incidence of hand dermatitis. there is also an enhanced another important concern is management of patients with autoimmune and chronic inflammatory disorders being treated with biologic drugs or immunosuppressants, psoriasis, atopic dermatitis, connective tissue diseases, and hidradenitis suppurativa ( ). european task force dermatology specific guidelines were published ( ), suggesting continuing all immune-modulating treatments, including immuno-suppressive therapy, since exacerbations of underlying diseases can have a large negative impact on patient immunity. it lamented that many conventional systemic immune-modulating agents, such as cyclosporine, may interact with the human body's defense mechanisms against viral disease, but warned that it is not currently known how sars-cov- affects atopic dermatitis patients and specifically those on immune-modulating therapies. public health policy is pivotal and varied ( , - ). at-home testing and monitoring for possible covid- represent a solid approach to keeping these covid- patients out of understaffed limited-equipment hospitals ( ). as another measure to prevent people from being hospitalized, it might be wise to actively discourage health care workers at high-risk, no matter how well-meaning, from being present at health care facilities, given both direct and fomite covid- spread. since risk is stratified by age, with deaths concentrated at older ages, and underlying co-morbidities, recommendations by us have been made (table ) . calling for older health care workers to volunteer is questionable. a study of covid- patients from wuhan, china stressed that patients more than years old and those with chronic diseases were at enhanced risk of severe covid- , and more likely to die ( ). a larger chinese study using multivariate cox regression analysis showed that age≥ , age between - years, coronary heart disease, cerebrovascular disease, and dyspnea were independent risk factors associated with fatal outcome ( ). neuropsychiatric sequelae of covid- should be a concern ( - ). we the continuing -ncov epidemic threat of novel coronaviruses to global health -the latest novel coronavirus outbreak in wuhan, china caution warranted: using the institute for health metrics and evaluation model for predicting the course of the covid- pandemic zhong ns; china medical treatment expert group for covid- . clinical characteristics of coronavirus disease in china toning down the -ncov media hype-and restoring hope incidence of thrombotic complications in critically ill icu patients with covid- prevalence of venous thromboembolism in patients with severe novel coronavirus pneumonia a pathological report of three covid- cases by minimally invasive autopsies epidemiological and clinical characteristics of cases of novel coronavirus pneumonia in wuhan, china: a descriptive study cutaneous manifestations in covid- : a first perspective key: cord- -r o ips authors: temiz, selami aykut; dursun, recep; daye, munise; ataseven, arzu title: evaluation of dermatology consultations in the era of covid date: -

( ) reported that the mean patient age was ± and mirkamali and al. ( ) reported the same to be ± . in our study, the mean age of the patients was ± , which was higher compared to the studies performed before the pandemic. this was thought to be due to the fact that elective patients were discharged during the pandemic period and patients who required urgent care, elderly patients and those who had comorbidities remained in the hospital. similar to pre-pandemic dermatology consultations, the ratio of males and females were found to be nearly the same in our study ( , , , ) . considering the dermatology consultations that took place before the pandemic, it was reported that pediatric patients constituted nearly to % of all dermatology consultations ( , ) . . % of our cases were dermatology consultations requested from pediatric departments. once again, considering the dermatology consultations requested in the pre-pandemic period, nearly -
