Intracerebroventricular administration of dynorphin-(1-13) inhibits dose-dependently plasma vasopressin level in normal as well as in water-deprived rats, whereas systemic (subcutaneous) administration of this opioid peptide is ineffective in this respect. Simultaneous subcutaneous, but not intracerebroventricular, administration of naloxone prevents the suppressive effect of dynorphin-(1-13) on plasma vasopressin levels.

Increasing evidence supports the presence of oxytocin deficiency (OXT-D) in patients with hypopituitarism and hypothalamic damage (HHD), that might be associated with neuropsychological deficits and sexual dysfunction, leading to worse quality of life (QoL). Therefore, identifying a provocative test to diagnose an OXT-D will be important. Corticotropin-releasing hormone (CRH) is a candidate for such a test as it increases oxytocin secretion in animal models.

Acute Kidney Injury (AKI) is a common complication in patients with Acute Respiratory Distress Syndrome (ARDS) receiving VV-ECMO support, carrying a high risk of progression to Renal Replacement Therapy (RRT). Both AKI and RRT are linked to an increased risk of mortality. This study aims to evaluate the risk factors associated with the need for RRT in patients undergoing VV-ECMO.

Background: Hyponatremia is one of the complicating findings in acute decompensated heart failure. Decrease in cardiac output and systemic blood pressure triggers activation of renin-angiotensin-aldosterone system, antidiuretic hormone, and norepinephrine due to the perceived hypovolemia. Fluid-overloaded heart failure patients are commonly treated with loop diuretics, acutely decompensated heart failure patients tend to be less responsive to conventional oral doses of a loop diuretic, while other different diuretics could work in different part of nephron circulation system.

Congenital diaphragmatic hernia (CDH) presents significant challenges in neonatal management, particularly in the context of anesthesia. This case report details the successful anesthetic management of a five-day-old neonate with left-sided CDH requiring thoracoscopic repair. A five-day-old neonate, delivered via emergency cesarean section due to breech presentation, presented with severe respiratory distress and was diagnosed with left-sided CDH.

Familial neurohypophyseal diabetes insipidus is a rare genetic disease caused by gene variants and is characterized by progressive polyuria and polydipsia in early childhood. Herein, we have reported the clinical symptoms and genetic test results of a Japanese patient with a family history of polyuria and polydipsia for over five generations. The proband was a 6-yr-old boy who was referred for the evaluation of polyuria and polydipsia.
