Sore Throat	2009-05-15		.txt	text/plain	5732	340	41	In the evaluation of a patient with sore throat, the primary concern is usually accurate diagnosis and treatment of pharyngitis caused by group A streptococci, which accounts for about 15% of all episodes of pharyngitis. Within 24 hours of institution of therapy with penicillin, it is difficult to isolate group A streptococci from patients with acute streptococcal pharyngitis, and infected children can return to school. In general, patients with a negative result of the rapid test do not require treatment before culture verification unless there is a particularly high suspicion group A streptococcal infection (e.g., scarlet fever, peritonsillar abscess, or tonsillar exudates in addition to tender cervical adenopathy, palatal petechiae, fever, and recent exposure to a person with group A streptococcal pharyngitis). Therapy with an appropriate antibiotic within 9 days of onset of symptoms is highly effective in preventing rheumatic fever, but acute glomerulonephritis is not prevented by treatment of the antecedent streptococcal infection.	./cache/cord-022281-xn0cf33a.txt	./txt/cord-022281-xn0cf33a.txt
