Nesidioblastosis in children.
Three cases in which seizure disorder was first noticed were examined in the last seven years; low fasting glucose and high serum insulin levels then led to the diagnosis of severe hypoglycemia secondary to nesidioblastosis. Hypoglycemic episodes were uncontrolled by frequent oral feedings and intravenous administration of dextrose, glucagon, and diazoxide. Within three weeks after diagnosis, all three patients underwent subtotal pancreatectomy; all three survived and have been followed-up for two to seven years. Two remain euglycemic and have no evidence of CNS damage. The third has occasional fasting hypoglycemia that is treated with diazoxide; he continues to have a seizure disorder and is mentally retarded. Neonatal hypoglycemia secondary to hyperinsulinism requires prompt recognition and aggressive treatment to avoid irreversible CNS damage. Subtotal pancreatectomy safely and effectively restores the euglycemic state.
