But in some cases it may be useful as it allows identifying the loss of normal circadian rhythm of cortisol secretion. This test is not rarely used in hospitalized patients when Cushing’s syndrome is suspected. But the cutt-off point of nighttime serum cortisol level for the diagnosis of hypercortisolism is inconsis...

Purpose: D631Y is a rare mutation associated with MEN2a in which there is an aspartic acid to tyrosine amino acid substitution at codon 631 in exon 11. Common clinical features of this variant of RET mutation are pheochromocytoma in 50%, medullary carcinoma in 30%, primary hyperparathyroidism is very rare. We present the patient harboring RET D631Y mutation.Clinical case: In April 2017 40-year-old woman was admitted to endocrine department of the Almazov...

Purpose: Transsphenoidal endoscopic surgery (TSS) is the first-line treatment for Cushing’s disease (CD). However, persistence of hypercortisolism after TSS considered important problem. In this case search for CD remission predictors is actual.Aim: To study the role of preoperative oral high-dose dexamethasone suppression test (HDDST) and pituitary magnetic resonance imaging (MRI) in the prognosis of CD remission after TSS.Ma...
