    Pure endoscopic management of epileptogenic hypothalamic hamartomas.
    Neurosurg Rev 2017 Feb 7. Epub 2017 Feb 7.
    Neurosurgery Department, Strasbourg University Hospital, Strasbourg, France.
    Hypothalamic hamartomas (HH) are rare congenital malformations located in the region of the tuber cinereum and third ventricle. Their usual clinical presentation is characterized by gelastic/dacrystic seizures which often become pharmaco-resistant and progress to secondary focal/generalized intractable epilepsy causing mostly in children cognitive and behavioral problems (particularly in cases of progressive epileptic encephalopathy) and precocious puberty. Whereas gelastic seizures can be surgically controlled either by resection of the lesion or disconnection (tissue-destructive) procedures, aimed at functionally prevent the spreading of the epileptic burst; generalized seizures tend to respond better to HH excision rather than isolated neocortical resections, which generally fail to control them.

    Hypercalcemia induces targeted autophagic degradation of aquaporin-2 at the onset of nephrogenic diabetes insipidus.
    Kidney Int 2017 Jan 27. Epub 2017 Jan 27.
    Systems Biology Center, Research Affairs, Faculty of Medicine, Chulalongkorn University, Bangkok, Thailand; Epithelial Systems Biology Laboratory, National Heart, Lung, and Blood Institute, Bethesda, Maryland, USA. Electronic address:
    Hypercalcemia can cause renal dysfunction such as nephrogenic diabetes insipidus (NDI), but the mechanisms underlying hypercalcemia-induced NDI are not well understood. To elucidate the early molecular changes responsible for this disorder, we employed mass spectrometry-based proteomic analysis of inner medullary collecting ducts (IMCD) isolated from parathyroid hormone-treated rats at onset of hypercalcemia-induced NDI. Forty-one proteins, including the water channel aquaporin-2, exhibited significant changes in abundance, most of which were decreased. Read More

    Nephrogenic diabetes insipidus.
    Curr Opin Pediatr 2017 Jan 27. Epub 2017 Jan 27.
    aUCL Institute of Child Health and Great Ormond Street Hospital for Children, NHS Foundation Trust, London, UK bDepartments of Medicine, Pharmacology and Physiology, Université de Montréal cUnité de recherche clinique, Centre de recherche et Service de néphrologie, Hôpital du Sacré-Coeur de Montreal, Montreal, Quebec, Canada.
    Purpose Of Review: In nephrogenic diabetes insipidus (NDI), the kidney is unable to concentrate urine despite elevated concentrations of the antidiuretic hormone arginine-vasopressin. In congenital NDI, polyuria and polydipsia are present from birth and should be immediately recognized to avoid severe episodes of dehydration. Unfortunately, NDI is still often recognized late after a 'diagnostic odyssey' involving false leads and dangerous treatments. Read More

    Amyloid-like aggregation of provasopressin in diabetes insipidus and secretory granule sorting.
    BMC Biol 2017 Jan 26;15(1). Epub 2017 Jan 26.
    Biozentrum, University of Basel, Klingelbergstrasse 70, CH-4056, Basel, Switzerland.
    Background: Aggregation of peptide hormone precursors in the trans-Golgi network is an essential process in the biogenesis of secretory granules in endocrine cells. It has recently been proposed that this aggregation corresponds to the formation of functional amyloids. Our previous finding that dominant mutations in provasopressin, which cause cell degeneration and diabetes insipidus, prevent native folding and produce fibrillar aggregates in the endoplasmic reticulum (ER) might thus reflect mislocalized amyloid formation by sequences that evolved to mediate granule sorting.

    Adipsic diabetes insipidus in adult patients.
    Pituitary 2017 Jan 10. Epub 2017 Jan 10.
    Academic Department of Endocrinology, Beaumont Hospital/RCSI Medical School, Beaumont Road, Dublin 9, Co., Dublin, Ireland.
    Introduction: Adipsic diabetes insipidus (ADI) is a very rare disorder, characterized by hypotonic polyuria due to arginine vasopressin (AVP) deficiency and failure to generate the sensation of thirst in response to hypernatraemia. As the sensation of thirst is the key homeostatic mechanism that prevents hypernatraemic dehydration in patients with untreated diabetes insipidus (DI), adipsia leads to failure to respond to aquaresis with appropriate fluid intake. This predisposes to the development of significant hypernatraemia, which is the typical biochemical manifestation of adipsic DI. Read More

    The neuroendocrine sequelae of paediatric craniopharyngioma: a 40-year meta-data analysis of 185 cases from three UK centres.
    Eur J Endocrinol 2017 Mar 10;176(3):359-369. Epub 2017 Jan 10.
    Royal Manchester Children's HospitalManchester, UK.
    Objectives: The management of paediatric craniopharyngiomas was traditionally complete resection (CR), with better reported tumour control compared to that by partial resection (PR) or limited surgery (LS). The subsequent shift towards hypothalamic sparing, conservative surgery with adjuvant radiotherapy (RT) to any residual tumour aimed at reducing neuroendocrine morbidity, has not been systematically studied. Hence, we reviewed the sequelae of differing management strategies in paediatric craniopharyngioma across three UK tertiary centres over four decades. Read More

    Norman M. Dott, master of hypothalamic craniopharyngioma surgery: the decisive mentoring of Harvey Cushing and Percival Bailey at Peter Bent Brigham Hospital.
    J Neurosurg 2017 Jan 6:1-14. Epub 2017 Jan 6.
    Department of Neurosurgery, La Princesa University Hospital, Madrid, Spain.
    Norman McOmish Dott (1897-1973) developed surgical neurology in Edinburgh, Scotland, and was a scholar of worldwide renown. One of Dott's most notable contributions to neurosurgery was his understanding of hypothalamic physiology, mostly acquired through the comprehensive study of patients with lesions involving this region of the diencephalon, particularly craniopharyngiomas (CPs). Recognition of symptoms caused by hypothalamic disturbances allowed him to predict the accurate anatomical relationships between CPs and the hypothalamus, despite the rudimentary radiological methods available during the 1930s.

    Liver X Receptor β (LXRβ) Increases AQP2 Protein Level via a Post-transcriptional Mechanism in Renal Collecting Ducts.
    Am J Physiol Renal Physiol 2017 Jan 4:ajprenal.00564.2016. Epub 2017 Jan 4.
    Dalian Medical University
    Liver X Receptors (LXRs) including LXRα and LXRβ are nuclear receptor transcription factors and play an important role in lipid and glucose metabolism. It has been previously reported that mice lacking LXRβ but not LXRα develop a severe urine concentrating defect, likely via a central mechanism. Here we provide evidence that LXRβ regulates water homeostasis through increasing aquaporin 2 (AQP2) protein levels in renal collecting ducts. Read More

    Central diabetes insipidus (CDI), characterized by polyuria and polydipsia, is caused by deficiency of arginine vasopressin (AVP), an antidiuretic hormone which acts on V2 receptors in kidney to promote reabsorption of free water. CDI is classified into three subtypes; idiopathic, secondary and familial. A previous study suggests that infundibulo-neurohypophysitis might be an underlying cause of idiopathic CDI. Read More

    Purpose: Patients affected by Cushing's disease often have important comorbidities directly linked to hypercortisolism that might enhance the operative risk. We report the safety of transsphenoidal surgery in patients affected by Cushing's disease as compared with patients with nonfunctioning pituitary adenoma.

    Methods: We have retrospectively analyzed 142 patients with Cushing's disease and 299 patients with nonfunctioning pituitary adenoma who underwent transsphenoidal surgery performed by a single experienced neurosurgeon between September 2007 and December 2014. Read More

    Central diabetes insipidus (CDI) results from a deficiency of arginine vasopressin (AVP) secretion. It is treated by replacement therapy with the synthetic AVP analogue desmopressin. To prevent heart failure in patients with CDI accompanied by cardiac dysfunction, controlling sodium and water intake is essential, using the minimum effective dose of desmopressin. Read More
