ISCHEMIC PITUITARY APOPLEXY, HYPOPITUITARISM AND DIABETES INSIPIDUS: A TRIAD UNIQUE TO NECROTIZING HYPOPHYSITIS.

- A rare case of necrotizing hypophysitis (NH) in a 52-year-old man presenting with pituitary apoplexy and sterile meningitis is described. This case indicates that the diagnosis of NH could be made without biopsy, based on concomitant presence of diabetes insipidus, hypopituitarism and radiologic features of ischemic pituitary apoplexy. Conservative management of pituitary apoplexy should be advised in NH.

Empty Sella in the Making.

Background: Pituitary apoplexy may occur when a large tumor compresses or outgrows its nutrient supply, resulting in ischemic necrosis and hemorrhage. Although once deemed a neurosurgical emergency, increasing evidence suggests that conservative management of pituitary apoplexy leads to favorable neuro-ophthalmologic and endocrinologic outcomes as well. Spontaneous remission after pituitary apoplexy has been described in functioning pituitary adenomas, but it is a rare occurrence in nonfunctioning tumors.

The Impact of Hyperosmolarity on Long-Term Outcome in Patients Presenting with Severe Hyperglycemic Crisis: A Population Based Study.

Aims: We compared characteristics of patients with hyperglycemic hyperosmolar state (HHS) and patients with severe hyperglycemia without the signs of hyperosmolarity and ketoacidosis; analyzed long-term all-cause mortality and potential prognostic factors.

Methods: The studied population included 261 749 adults. HHS was diagnosed in patients with plasma glucose >33.

Diabetic ketosis during hyperglycemic crisis is associated with decreased all-cause mortality in patients with type 2 diabetes mellitus.

Patients with type 2 diabetes mellitus have impaired ketogenesis due to high serum insulin and low growth hormone levels. Evidence exists that ketone bodies might improve kidney and cardiac function. In theory, improved ketogenesis in diabetics may have positive effects.
