SF consumed less calcium, presumably to prevent more stones, and displayed a bone mineral responsiveness to calcium loss and ammonium excretion not present among NSF, who ate more calcium. Lowered calcium consumption in IH, perhaps in response to stone formation, alters bone responses in a direction that can predispose to mineral loss and eventual fracture.

We report the first pediatric case of drug reaction with eosinophilia and systemic symptoms associated with azithromycin use in the setting of acute Epstein-Barr virus infection in an 8-year-old boy. Our patient presented with fever, cutaneous eruption, eosinophilia, and hypotension requiring intensive care unit admission. He was discharged in good condition without any long-term sequelae. This case underscores the importance of timely and accurate diagnosis of acute viral infections and appropriate use of antibiotics as well as recognition of the clinical signs of drug reaction with eosinophilia and systemic symptoms.
