A 16-year-old boy develops a diffuse, rapidly progressive eruption on his trunk, face, and extremities 4 days after starting oral amoxicillin for presumed strep throat. He presents to the emergency department (ED) where Stevens-Johnson syndrome is considered. The ED physician notes no mucous membrane involvement.

Investigators compared the accuracy of an American Academy of Pediatrics (AAP) practice guideline algorithm for diagnosing of urinary tract infection (UTI) in 2- to 23-month-olds with a new tool (UTICalc; University of Pittsburgh, Pennsylvania) that first estimates UTI probability based on clinical variables and then, if laboratory testing is performed, updates the estimate based on the results.
