Immunoglobulin G4 hypophysitis in a 63-year-old woman with no autoimmune history: a case report.

Background: Immunoglobulin-G4-related hypophysitis is a rare inflammatory disease that can present as a tumefactive pituitary lesion mimicking hypophyseal neoplasms such as pituitary adenoma or craniopharyngioma. The literature on this entity is sparse, with fewer than 100 cases reported across 19 publications; a recent review found only 24 cases published from 2007 to 2018. Previous reports have described demographic differences, with immunoglobulin-G4-related hypophysitis in females tending to present in the second and third decades in association with other autoimmune disease, while males tend to present in the fifth and sixth decades of life without an autoimmune history.

A novel endocrinology-based wellness program to reduce medication expenditures and improve glycemic outcomes.

Aims: The purpose of this study was to determine the difference in diabetes-related medication expenditures as a result of a 16-week lifestyle intervention program. Medical expenditures for patients with diabetes are twice as high compared to patients without this condition. Secondary objectives were changes in HbA1C, BMI, weight, body fat, and program satisfaction.

Hypoglycemia-associated autonomic failure in advanced type 2 diabetes.

We tested the hypotheses that the glucagon response to hypoglycemia is reduced in patients who are approaching the insulin-deficient end of the spectrum of type 2 diabetes and that recent antecedent hypoglycemia shifts the glycemic thresholds for autonomic (including adrenomedullary epinephrine) and symptomatic responses to hypoglycemia to lower plasma glucose concentrations in type 2 diabetes. Hyperinsulinemic stepped hypoglycemic clamps (85, 75, 65, 55, and 45 mg/dl steps) were performed on two consecutive days, with an additional 2 h of hypoglycemia (50 mg/dl) in the afternoon of the first day, in 13 patients with type 2 diabetes---7 treated with oral hypoglycemic agents (OHA R(X); mean [+/- SD] HbA(1c) 8.6 +/- 1.
