Glucose-responsive Insulinoma Diagnosed Using Somatostatin Receptor Scintigraphy and Intraoperative Intravenous Glucose Tolerance Test—A Case Report—

Glucose-responsive and octreotide-sensitive insulinoma.

Insulinoma is the most common cause of fasting hypoglycemia resulting from autonomous insulin hypersecretion. We describe herein a unique case with paradoxical hypoglycemic episodes induced by hyperglycemia. A 55-year-old female had repeated hypoglycemic episodes after meal or during increased physical activity. Although fasting (10 hr) failed to provoke hypoglycemia, oral glucose tolerance tes...

Intravenous Glucose Tolerance Test and Glucose Kinetic Parameters in Rabbits

The purpose of this study was to determine the normal range and test variability for intravenous glucose tolerance test (IVGTT) in rabbits. Fifty one clinically healthy New Zealand white rabbits of both sexes (31 female and 20 male), 3.5−4 months of age and weighing 2.8 to 3.7 kg were used. The IVGTT was performed after an overnight fasting period of 12 h by intravenous injection of 40% glucose...

Intravenous Glucose Tolerance Test in Normal Persons

as a supplement to the oral method has been pointed out by many workers. Moreover, the possibility of error in the result of oral method due to diminished absorption has been shown by Beeler, Bryan, Cathcart and Fitz (1922). The flat blood sugar curve obtained by Thaysen (1929) after the oral administration of glucose, as has been shown by the author, is due to the diminished absorption of gluc...
