Excerpt From This Issue
A 20-month-old boy presents to the ED with a cough and fever for 3 days. He has no past medical history, and his routine vaccinations are up-to-date. His parents say he has been eating less than usual; however, his urine output is normal, and he has had no vomiting or diarrhea. Vital signs are: temperature, 39.6˚C (103.2°F); heart rate, 156 beats/min; respiratory rate, 32 breaths/ min; and oxygen saturation, 100% on room air. He is well-appearing, although his left tympanic membrane is erythematous and bulging, with apparent middle-ear purulence. You make the diagnosis of otitis media in the setting of a presumed viral upper respiratory infection. While preparing the discharge papers, you consider the many patients you’ve seen during the current flu epidemic and wonder whether treatment for influenza would be appropriate . . .
