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.

[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.
