    Pitfall in the Diagnosis of Diabetes Insipidus and Pregnancy.
    Case Rep Obstet Gynecol 2017 27;2017:7879038. Epub 2017 Jul 27.
    Department of Medicine, College of Physicians and Surgeons, Columbia University, New York, NY, USA.
    Diabetes insipidus (DI) during pregnancy and the perinatal period is an uncommon medical problem characterized by polyuria and excessive thirst. Diagnosis of DI may be overlooked in the setting of pregnancy, a time when increased water intake and urine output are commonly reported. We report two cases: one of transient DI in a young woman during her third trimester of twin pregnancy in association with acute fatty liver and hypertension and one of postpartum DI secondary to Sheehan syndrome from rupture of a splenic artery aneurysm.

    Renal Sodium Gradient Orchestrates a Dynamic Antibacterial Defense Zone.
    Cell 2017 Aug 8. Epub 2017 Aug 8.
    Molecular Immunity Unit, Department of Medicine, University of Cambridge, Cambridge CB2 0QQ, UK. Electronic address:
    Lower urinary tract infections are among the most common human bacterial infections, but extension to the kidneys is rare. This has been attributed to mechanical forces, such as urine flow, that prevent the ascent of bladder microbes. Here, we show that the regional hypersalinity, required for the kidney's urine-concentrating function, instructs epithelial cells to produce chemokines that localize monocyte-derived mononuclear phagocytes (MNPs) to the medulla.

    Copeptin as a marker of an altered CRH axis in pituitary disease.
    Endocrine 2017 Aug 9. Epub 2017 Aug 9.
    Experimental and Clinical Endocrinology Med Clinic I, University of Luebeck, Ratzeburger Allee 160, 23538, Lübeck, Germany.
    Background: Copeptin (pre-proAVP) secreted in equimolar amounts with vasopressin closely reflects vasopressin release. Copeptin has been shown to subtly mirror stress potentially mediated via corticotrophin-releasing hormone. To further test a potential direct interaction of corticotrophin-releasing hormone with copeptin release, which could augment vasopressin effects on pituitary function, we investigated copeptin response to corticotrophin-releasing hormone.

    Do craniopharyngioma molecular signatures correlate with clinical characteristics?
    J Neurosurg 2017 Jul 14:1-6. Epub 2017 Jul 14.
    Departments of 1 Neurosurgery.
    OBJECTIVE Exome sequencing studies have recently demonstrated that papillary craniopharyngiomas (PCPs) and adamantinomatous craniopharyngiomas (ACPs) have distinct genetic origins, each primarily driven by mutually exclusive alterations: either BRAF ( V600E), observed in 95% of PCPs, or CTNNB1, observed in 75%-96% of ACPs. How the presence of these molecular signatures, or their absence, correlates with clinical, radiographic, and outcome variables is unknown. METHODS The pathology records for patients who underwent surgery for craniopharyngiomas between May 2000 and March 2015 at Weill Cornell Medical College were reviewed. Read More

    Ann Endocrinol (Paris) 2016 Oct;77 Suppl 1:S11-S18
    Fédération d'Endocrinologie, Hospices Civils de Lyon, Groupement Hospitalier Est, 59 Boulevard Pinel, 69677 Bron, France; Université Lyon 1, 43 Boulevard du 11 novembre 1918, 69100 Villeurbanne, France.
    Diabetes insipidus is a syndrome that associates both hypotonic polyuria and polydipsia, due to insufficient or ineffective arginine vasopressin (AVP) synthesis, or to AVP resistance. The diagnosis between central/renal origin, or an abnormal thirst regulation (primary polydipsia) is required to organize an adapted management. Because water deprivation tests are not reliable, it's often based on medical history, response to treatment and MRI. Read More

    Long-Standing Isolated Autoimmune Hypothalamitis Diagnosed with Endoscopic Transventricular Biopsy.
    World Neurosurg 2017 Jun 16. Epub 2017 Jun 16.
    Unit of Neurosurgery, Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, Milan, Italy.
    Background: Autoimmune hypothalamitis, which is among the causes of acquired central diabetes insipidus, has seldom been described in the literature. This condition is probably provoked by the production of anti-vasopressin-secreting cell antibodies and antihypothalamus antibodies and is often associated with pituitary or polyendocrine autoimmunity. Correct diagnosis and immediate treatment are essential to avoid the progression of the pathologic process. Read More

    Association between Ischemic Stroke and Erdheim-Chester Disease: A Case Report and Review of Literature.

    Lithium-induced NDI: Acetazolamide reduces polyuria, but does not improve urine concentrating ability.
    Am J Physiol Renal Physiol 2017 Jun 14:ajprenal.00147.2017. Epub 2017 Jun 14.
    Radboud University Nijmegen Medical Centre
    Lithium is the mainstay treatment for patients with bipolar disorder, but generally causes nephrogenic diabetes insipidus (NDI), a disorder in which the renal urine concentrating ability has become vasopressin-insensitive. Li-NDI is caused by lithium uptake by collecting duct principal cells and downregulation of AQP2 water channels, which are essential for water uptake from pro-urine. Recently, we found that the prophylactic administration of acetazolamide to mice effectively attenuated Li-NDI. Read More

    Hypopituitarism is associated with lower oxytocin concentrations and reduced empathic ability.
    Endocrine 2017 Jul 8;57(1):166-174. Epub 2017 Jun 8.
    Neuroscience and Mental Health Research Institute, School of Medicine, Cardiff University, Cardiff, CF24 4HQ, UK.
    Purpose: Central diabetes insipidus is characterised by arginine vasopressin deficiency. Oxytocin is structurally related to vasopressin and is synthesised in the same hypothalamic nuclei, thus we hypothesised that patients with acquired central diabetes insipidus and anterior hypopituitarism would display an oxytocin deficiency. Moreover, psychological research has demonstrated that oxytocin influences social and emotional behaviours, particularly empathic behaviour. Read More

    Opioid-induced hyponatremia in a patient with central diabetes insipidus: independence from ADH.
    J Pediatr Endocrinol Metab 2017 May;30(6):693-696
    .
    Hyponatremia can be a complication of opioid therapy, which has been postulated to occur secondary to inappropriate antidiuretic hormone secretion (syndrome of inappropriate antidiuretic hormone secretion [SIADH]). We report severe hyponatremia following wisdom teeth extraction with opioid analgesia in a 19-year-old female with diabetes insipidus (DI) and acquired panhypopituitarism that challenges this theory. As this patient has DI, we believe opioid treatment caused severe hyponatremia by the following mechanisms: (1) Opioids have a direct antidiuretic effect independent of changes in ADH, as demonstrated in Brattleboro rats with central DI. Read More

    A reformed surgical treatment modality for children with giant cystic craniopharyngioma.
    Childs Nerv Syst 2017 Jun 7. Epub 2017 Jun 7.
    Department of Pediatric Neurosurgery, Beijing Tiantan Hospital, Capital Medical University, Beijing, 100050, China.
    Objective: Surgical removal plays an important role in treating children's craniopharyngioma. For a safe and minimally invasive craniotomy, a reformed surgical modality was proposed in this paper by combining the insertion of an Ommaya reservoir system (ORS) by stereotactic puncture, aspiration of cystic fluid in 2-day interval for consecutive 7-10 days, and the delayed tumor resection.

    Patients And Methods: Eleven patients (aged from 5 to 9 years old) with giant cystic craniopharyngiomas who had undergone the reformed surgical modality during November 2014 and December 2015 were collected as group A. Read More

    Hypothalamic hamartoma with epilepsy: Review of endocrine comorbidity.
    Epilepsia 2017 Jun;58 Suppl 2:50-59
    Pediatric Neurology Division and Hypothalamic Hamartoma Program, Barrow Neurological Institute at Phoenix Children's Hospital, Phoenix, Arizona, U.S.A.
    The most common, and usually the only, endocrine disturbance in patients with hypothalamic hamartoma (HH) and epilepsy is central precocious puberty (CPP). The mechanism for CPP associated with HH may relate to ectopic generation and pulsatile release of gonadotropin-releasing hormone (GnRH) from the HH, but this remains an unproven hypothesis. Possible regulators of GnRH release that are intrinsic to HH tissue include the following: (1) glial factors (such as transforming growth factor α[TGFα) and (2) γ-aminobutyric acid (GABA)-mediated excitation.
