Predicting the location of the preoptic and anterior hypothalamic region by visualizing the thermoregulatory center on fMRI in craniopharyngioma using cold and warm stimuli.

Aging (Albany NY) 2021 Mar 26;13. Epub 2021 Mar 26.

Department of Neurosurgery, Beijing Tiantan Hospital, Capital Medical University, Beijing, China.

Hypothalamic nuclei in the preoptic and anterior hypothalamic region (POAH) are critically involved in thermoregulation and neuroendocrine regulation and can be displaced by craniopharyngiomas (CPs). We aimed to locate the POAH by visualizing hypothalamic thermoregulation through task-related functional magnetic resonance imaging (fMRI) to guide hypothalamus protection intraoperatively. Nine adult healthy volunteers (HVs) and thirty-two adult primary CP patients underwent task-related fMRI for POAH localization by warm (60° C) and cold (0° C) cutaneous thermoreceptor stimulation.

Electronic address:

Surgical failure or recurrence of Cushing's disease can be treated with medical therapy, radiotherapy, adrenalectomy, and/or repeat transsphenoidal surgery, all of which have their respective benefits and drawbacks. Redo transsphenoidal surgery has been shown to achieve at least short-term remission in about 40-80% of patients and is associated with low rates of morbidity and near-zero mortality, albeit higher rates of postoperative hypopituitarism, diabetes insipidus, and cerebrospinal fluid leak than initial resection. Despite this, recurrence may ensue in 50% of patients. Read More

Vasopressin-Dependent Disorders: What Is New in Children?

Pediatrics 2021 Apr 1. Epub 2021 Apr 1.

Division of Pediatric Endocrinology and Metabolism, Mayo Clinic, Rochester, Minnesota

Arginine vasopressin (AVP)-mediated osmoregulatory disorders, such as diabetes insipidus (DI) and syndrome of inappropriate secretion of antidiuretic hormone (SIADH) are common in the differential diagnosis for children with hypo- and hypernatremia and require timely recognition and treatment. DI is caused by a failure to concentrate urine secondary to impaired production of or response to AVP, resulting in hypernatremia. Newer methods of diagnosing DI include measuring copeptin levels; copeptin is AVP's chaperone protein and serves as a surrogate biomarker of AVP secretion. Read More

Cureus 2021 Feb 23;13(2):e13523. Epub 2021 Feb 23.

Basic Sciences, Nova Southeastern University Dr. Kiran C. Patel College of Osteopathic Medicine, Fort Lauderdale, USA.

Diabetes insipidus (DI) is an endocrine condition involving the posterior pituitary peptide hormone, antidiuretic hormone (ADH). ADH exerts its effects on the distal convoluted tubule and collecting duct of the nephron by upregulating aquaporin-2 channels (AQP2) on the cellular apical membrane surface. DI is marked by expelling excessive quantities of highly dilute urine, extreme thirst, and craving for cold water. Read More

Rapid Development of Vasopressin Resistance in Dietary Potassium Deficiency.

Am J Physiol Renal Physiol 2021 Mar 22. Epub 2021 Mar 22.

Department of Medicine and Physiology, Johns Hopkins University School of Medicine, United States.

The association between diabetes insipidus (DI) and chronic dietary potassium deprivation is well known but it remains uncertain how the disorder develops and whether it is influenced by the sexual dimorphism in potassium handling. Here, we determine the plasma potassium (P) threshold for DI in male and female mice and ascertain if the DI is initiated by polydipsia, or a central or nephrogenic defect. C57BL6J mice were randomized to a control diet or to graded reductions in dietary K for 8 days, and kidney function and transporters involved in water balance were characterized. Read More

Diagnosis and management of diabetes insipidus for the internist: an update.

J Intern Med 2021 Mar 13. Epub 2021 Mar 13.

From the, Clinic for Endocrinology, Diabetes and Metabolism, University Hospital Basel, University of Basel, Basel, Switzerland.

Diabetes insipidus is a disorder characterized by excretion of large amounts of hypotonic urine. Four entities have to be differentiated: central diabetes insipidus resulting from a deficiency of the hormone arginine vasopressin (AVP) in the pituitary gland or the hypothalamus, nephrogenic diabetes insipidus resulting from resistance to AVP in the kidneys, gestational diabetes insipidus resulting from an increase in placental vasopressinase and finally primary polydipsia, which involves excessive intake of large amounts of water despite normal AVP secretion and action. Distinguishing between the different types of diabetes insipidus can be challenging. Read More
