Insulinoma-related Endogenous Hypoglycaemia with a Negative Fasting Test: A Case Report and Literature Review.

Unlabelled: We present the case of a patient with a history of symptomatic hypoglycaemic episodes and a negative 72-hour fasting test with histological confirmation of insulinoma. A literature review of hyperinsulinaemic hypoglycaemia with a negative fasting test was performed.

Learning Points: The 72-hour fasting test is the gold standard for insulinoma diagnosis.

Adrenal venous sampling in a patient with adrenal Cushing syndrome.

The primary bilateral macronodular adrenal hyperplasia or the independent adrenocorticotropic hormone bilateral nodular adrenal hyperplasia is a rare cause hypercortisolism, its diagnosis is challenging and there is no clear way to decide the best therapeutic approach. Adrenal venous sampling is commonly used to distinguish the source of hormonal production in patients with primary hyperaldosteronism.

[Complications associated with hyperglycemia in liver transplant patients].

Background: Hyperglycemia is a frequent phenomenon in hospitalized patients that is associated with negative outcomes. It is common in liver transplant patients as a result of stress and is related to immunosuppressant drugs. Although studies are few, a history of diabetes and the presentation of hyperglycemia during liver transplantation have been associated with a higher risk for rejection.
