Risk Factors for Development of Diabetes Insipidus and Syndrome of Inappropriate Antidiuretic Hormone Secretion after Transsphenoidal Resection of Pituitary Adenoma.

We aimed to determine the incidence and risk factors for development of diabetes insipidus (DI) and syndrome of inappropriate antidiuretic hormone secretion (SIADH) after transsphenoidal hypophysectomy (TSH) for resection of a pituitary adenoma. This was a retrospective study of 403 adult patients undergoing TSH for pituitary adenoma. Clinical variables, tumor characteristics, and operative factors were collected.

Transient polyuria during pregnancy is reportedly caused by increased arginine vasopressin (AVP) degradation due to vasopressinase produced by the placenta. The mechanism underlying transient polyuria during pregnancy has not been established. In this study we measured urine volume, urine osmolality, and AVP transcriptional activity during pregnancy in wild-type and familial neurohypophysial diabetes insipidus (FNDI) mice.

Refractory cancer pain affects 10-20% of patients with advanced malignancies and is not adequately controlled by opioids. The intrathecal therapy is an effective interventional procedure for referral, but the implanted infusion pumps are costly and the refilling requires technical expertise. Hypophysectomy, in its three stages-surgical, chemical, and radiosurgical-has emerged as an alternative for managing this pain.

Its deficiency is associated with endocrinopathies comparable to those caused by proprotein convertase1/3(PC1/3) deficiency. In this case report we expand the clinical features of CPE deficiency by examining the index case's clinical/laboratory results, which are also indicative of PC1/3 deficiency.

Background: Arginine infusion stimulates copeptin secretion, a surrogate marker of arginine vasopressin (AVP), thereby serving as a diagnostic test in the differential diagnosis of suspected AVP deficiency (AVP-D). Yet, the precise mechanism underlying the stimulatory effect of arginine on the vasopressinergic system remains elusive. Arginine plays a significant role in the urea cycle and increases the production of urea.
