As yet, there has been little application of this test to infants and children. In four children with idiopathic hypoglycemia Fajans ^2,3 noted a return to normal fasting range between two and three hours. Klein ⁶ and co-workers reported results of intravenous tolbutamine on 12 healthy children in 1958. Grumbach and Kaplan ⁷ reported a normal response to 25 mg/kg tolbutamide in one child with leucine-sensitive hypoglycemia. Recently DiGeorge and Chiowanich ⁸ obtained normal responses from 15 healthy children and 11 patients with cystic fibrosis. Two infants with hypoglycemia studied by these workers gave responses suggesting adenoma on . . . [Full Text PDF of this Article]
