    Clinical presentation and outcome of children with central diabetes insipidus associated with a self-limited or transient pituitary stalk thickening, diagnosed as infundibuloneurohypophysitis.
    Clin Endocrinol (Oxf) 2017 Apr 26. Epub 2017 Apr 26.
    Division of Pediatric Endocrinology, Vrije Universiteit Brussel, UZ Brussel Kinderziekenhuis, Brussels.
    Objective: Despite lymphocytic or autoimmune infundibuloneurohypophysitis (INH) is an increasingly recognized etiology in children with central diabetes insipidus, clinical data on epidemiology (clinical evolution, predisposing factors, complications), diagnosis and management of this entity are limited and mostly based on published case reports. The aim of this study was to gain a broader insight in the natural history of this disease by analyzing the clinical presentation, radiological pituitary stalk changes, associated autoimmunity and hormonal deficiencies in children with CDI and a self-limiting or transient stalk thickening (ST), diagnosed as autoimmune INH, during the last 15 years in four Belgian university hospitals.

    Design And Patients: The medical files of nine CDI patients with a ST at initial presentation and no signs of Langerhans cell histiocytosis or germinoma at presentation and/or during follow up of more than 1. Read More

    Role of adenylyl cyclase 6 in the development of lithium-induced nephrogenic diabetes insipidus.
    JCI Insight 2017 Apr 6;2(7):e91042. Epub 2017 Apr 6.
    InterPrET Center, Department of Biomedicine, Aarhus University, Aarhus, Denmark.
    Psychiatric patients treated with lithium (Li(+)) may develop nephrogenic diabetes insipidus (NDI). Although the etiology of Li(+)-induced NDI (Li-NDI) is poorly understood, it occurs partially due to reduced aquaporin-2 (AQP2) expression in the kidney collecting ducts. A mechanism postulated for this is that Li(+) inhibits adenylyl cyclase (AC) activity, leading to decreased cAMP, reduced AQP2 abundance, and less membrane targeting. Read More

    Department of Medicine, Division of Endocrinology, Diabetes and Metabolism, Johns Hopkins University, 1830 East Monument Street #333, Baltimore, MD 21287, USA.
    Sellar and parasellar masses are a common finding, and most of them are treated surgically via transsphenoidal approach. This type of surgery has revolutionized the approach to several hypothalamic-pituitary diseases and is usually effective, and well-tolerated by the patient. However, given the complex anatomy and high density of glandular, neurological and vascular structures in a confined space, transsphenoidal surgery harbors a substantial risk of complications.

    Value of Renal Biopsy in Diagnosing Infantile Nephropathic Cystinosis Associated With Secondary Nephrogenic Diabetes Insipidus.
    Pediatr Dev Pathol 2017 Jan-Feb;20(1):72-75
    3 Division of Pediatric Pathology, Children's Hospital of Pittsburgh of UPMC, University of Pittsburgh School of Medicine, Pittsburgh, Pennsylvania, USA.
    Cystinosis is the most common cause of inherited renal Fanconi syndrome in young children, and typically presents with laboratory findings of a proximal tubulopathy and corneal crystals by one year of age. We describe here renal biopsy findings in a 20-month-old patient with an atypical presentation of distal renal tubular acidosis, diabetes insipidus, and the absence of corneal crystals. Although renal biopsy is usually not necessary to establish the diagnosis of cystinosis, when the patient presents with atypical signs and symptoms, a renal biopsy may be extremely valuable.

    Background: Wolfram syndrome (WS) is a disorder characterized by the association of insulin-dependent diabetes mellitus (DM), diabetes insipidus, deafness, and optic nerve atrophy. WS is caused by WFS1 mutations encoding WFS1 protein expressed in endoplasmic reticulum (ER). During ER protein synthesis, misfolded and unfolded proteins accumulate, known as "ER stress". Read More

    Jean Camus and Gustave Roussy: pioneering French researchers on the endocrine functions of the hypothalamus.
    Pituitary 2017 Mar 6. Epub 2017 Mar 6.
    Department of Neurosurgery, La Princesa University Hospital, Madrid, Spain.
    At the beginning of the twentieth century, the hypothalamus was known merely as an anatomical region of the brain lying beneath the thalamus. An increasing number of clinicopathological reports had shown the association of diabetes insipidus and adiposogenital dystrophy (Babinski-Fröhlich's syndrome), with pituitary tumors involving the infundibulum and tuber cinereum, two structures of the basal hypothalamus. The French physicians Jean Camus (1872-1924) and Gustave Roussy (1874-1948) were the first authors to undertake systematic, controlled observations of the effects of localized injuries to the basal hypothalamus in dogs and cats by pricking the infundibulo-tuberal region (ITR) with a heated needle.

    Rapid exacerbation of lymphocytic infundibuloneurohypophysitis.
    Medicine (Baltimore) 2017 Mar;96(9):e6034
    aDepartment of Diabetes, Endocrinology and Nutrition, Graduate School of Medicine, Kyoto University, Kawahara-cho, Shogoin, Sakyo-ku, Kyoto, Japan bDepartment of Endocrinology and Diabetes, Nagoya University Graduate School of Medicine, Nagoya, Japan. cDepartment of Neurosurgery, Graduate School of Medicine, Kyoto University, Kawahara-cho, Shogoin, Sakyo-ku, Kyoto, Japan.
    Rationale: Lymphocytic hypophysitis is a relatively rare autoimmune disease defined by lymphocytic infiltration to the pituitary. Its rarity and wide spectrum of clinical manifestations make clarification of the pathology difficult. Here, we describe a case we examined from the primary diagnosis to final discharge, showing the serial progression of lymphocytic infundibuloneurohypophysitis (LINH) to panhypopituitarism with extrapituitary inflammatory invasion in a short period, and responding favorably to high-dose glucocorticoid treatment.

    Hyperactivation of Nrf2 in early tubular development induces nephrogenic diabetes insipidus.
    Nat Commun 2017 Feb 24;8:14577. Epub 2017 Feb 24.
    Department of Medical Biochemistry, Tohoku University Graduate School of Medicine, 2-1 Seiryo-machi, Aoba-ku, Sendai 980-8575, Japan.
    NF-E2-related factor-2 (Nrf2) regulates cellular responses to oxidative and electrophilic stress. Loss of Keap1 increases Nrf2 protein levels, and Keap1-null mice die of oesophageal hyperkeratosis because of Nrf2 hyperactivation. Here we show that deletion of oesophageal Nrf2 in Keap1-null mice allows survival until adulthood, but the animals develop polyuria with low osmolality and bilateral hydronephrosis. Read More

    The endoplasmic reticulum (ER) is the organelle where secretory and membrane proteins are synthesized and folded. Unfolded proteins that are retained within the ER can cause ER stress. Eukaryotic cells have a defense system called the "unfolded protein response" (UPR), which protects cells from ER stress. Read More

    Advances in the management of traumatic brain injury, subarachnoid haemorrhage and intracranial tumours have led to improved survival rates and an increased focus on quality of life of survivors. Endocrine sequelae of the acute brain insult and subsequent neurosurgery, peri-operative fluid administration and/or cranial irradiation are now well described. Unrecognised acute hypopituitarism, particularly ACTH/cortisol deficiency and diabetes insipidus, can be life threatening. Read More

    Dept of Endocrinology, PGIMER, Chandigarh, India.
    Background: Vasospasm following craniopharyngioma surgery, though rare, has been reported. Hypotheses regarding possible causative factors including major vessel handling during surgery and tumour cyst fluid spillage do not explain vasospasm occurring in the late post operative period. We have attempted to look into the probable pathogenic mechanisms of this complication and measures to prevent it. Read More
