For pediatric practitioners, acute otitis media (AOM) and group A streptococcal pharyngitis are two of the most common infections seen in ambulatory practices. The purpose of this article is to review these conditions with the focus of highlighting evidence-based guidelines. AOM in children is a visual diagnosis and not one that can be made on history alone. The American Academy of Pediatrics (AAP) guidelines have clear criteria to aid clinicians in how to diagnose AOM. The pneumatic otoscope is the standard tool used to diagnose otitis media, and the AAP guidelines stress developing proficiency in distinguishing a normal tympanic membrane from otitis media with effusion or AOM. There are several components to appropriate management (treatment) of AOM including analgesia, education, antibiotics, and the option (for some) for observation. Group A streptococcal pharyngitis is the most common bacterial cause of sore throat in children but still only accounts for a minority of cases. History and physical examination help determine who should be tested. Testing is required to determine who to treat. Up to 15% of children in the United States are carriers, so indiscriminate testing can lead to inappropriate antibiotic use. If a patient's test is positive, treatment is recommended and penicillin or amoxicillin are appropriate for most cases. [Pediatr Ann. 2019;48(9):e343-e348.].
