Apoplexy of a microprolactinoma during pregnancy: case report and review of literature.

Objective: To report a rare case of apoplexy in a microprolactinoma during pregnancy.

Methods: We present the initial clinical manifestations, laboratory results, radiologic findings, and management in a patient who had pituitary apoplexy during early pregnancy. The pertinent literature and management options are also reviewed.

Effects of a diet higher in carbohydrate/lower in fat versus lower in carbohydrate/higher in monounsaturated fat on postmeal triglyceride concentrations and other cardiovascular risk factors in type 1 diabetes.

Objective: To compare the effects of a eucaloric diet higher in carbohydrate/lower in fat versus lower in carbohydrate/higher in monounsaturated fat on postmeal triglyceride (TG) concentrations and other cardiovascular disease risk factors in nonobese subjects with type 1 diabetes and in good glycemic control.

Research Design And Methods: In a parallel group design study, 30 subjects were randomly assigned and completed one of the two eucaloric diets. Assessments included: BMI, blood pressure, A1C, plasma lipids, and markers of oxidation, thrombosis, and inflammation.

Long-term cabergoline therapy is not associated with valvular heart disease in patients with prolactinomas.

Ergot-derived dopamine receptor agonists, especially pergolide and cabergoline, have been associated with an increased risk of valvular heart disease in patients treated for Parkinson's disease. Cabergoline at lower doses than those employed in Parkinson's disease is widely used in patients with prolactinomas, because of its high efficacy and tolerability; however, its safety with regard to cardiac valve disease is unknown. In order to assess the prevalence of cardiac valve regurgitation in patients with prolactinomas treated with long-term cabergoline, we performed a prospective and multicentric study including four university centers in the province of Quebec.

Impact of a high-monounsaturated-fat diet on lipid profile in subjects with type 1 diabetes.

Objective: Controversy persists regarding the use of a high-monounsaturated-fat diet in people with type 1 diabetes. The purpose of this study was to compare the effects of a high-monounsaturated-fat diet containing 43% to 46% carbohydrates and 37% to 40% fat (17% to 20% monounsaturated fat) with those of a high-carbohydrate diet containing 54% to 57% carbohydrates and 27% to 30% fat (10% to 13% monounsaturated fat) on the quantitative and qualitative lipoprotein profile in type 1 diabetes.

Design: A randomized crossover study was conducted.

Diagnosis and treatment of diabetic ketoacidosis and the hyperglycemic hyperosmolar state.

Diabetic ketoacidosis and the hyperglycemic hyperosmolar state are the most serious complications of diabetic decompensation and remain associated with excess mortality. Insulin deficiency is the main underlying abnormality. Associated with elevated levels of counterregulatory hormones, insulin deficiency can trigger hepatic glucose production and reduced glucose uptake, resulting in hyperglycemia, and can also stimulate lipolysis and ketogenesis, resulting in ketoacidosis.
