Cough	2009-05-15		.txt	text/plain	13122	733	48	A normal chest radiograph indicates the unlikelihood of pneumonia caused by respiratory syncytial virus (RSV), influenza, parainfluenza, adenovirus, Chlamydia species, or bacteria. Although children with cough resulting from CF, Mycoplasma species, tuberculosis, aspiration, a bronchial foreign body, or an anatomic abnormality usually have abnormal chest radiographs, a normal radiograph does not exclude these diagnoses. Sputum cultures and Gram stains may help guide initial empirical therapy in older patients with pneumonia or purulent bronchitis, but their ability to identify specific causative organisms with certainty (again with the exception of CF) has not been shown clearly. Bacterial pneumonia is relatively less common in infants than is viral pneumonia but can cause severe illness, with cough, respiratory distress, and fever. Treatment is similar to that for CF, with regular chest physical therapy and frequent and aggressive use of antibiotics at the first sign of airways infection, most commonly increased cough.	./cache/cord-022292-msz4au4b.txt	./txt/cord-022292-msz4au4b.txt
