Alberto, a 7-Year-Old Boy with Edema

CASE PRESENTATION You have finished morning rounds when you are asked to see Alberto, a 7-year-old boy who has just arrived as a direct admission. Alberto’s pediatrician requested admission because Alberto, who has allergic rhinitis, developed facial swelling in the context of taking amoxicillin-clavulanate for a presumed sinus infection. He had reassuring vital signs in the clinic and was in no distress, but he was noted to have weight gain from his most recent office visit and has new swelling of his ankles. Alberto was unable to provide a urine sample in the clinic, and his pediatrician has requested that you expedite his evaluation and management.
