    [Hypercalcaemia due to the milk-alkali syndrome].
    Ugeskr Laeger 2018 Feb;180(7)
    This case report is about an 87-year-old woman with Alzheimer's disease and the milk-alkali syndrome, who took calcium carbonate as osteoporosis prophylaxis. We describe, how the milk-alkali syndrome can result in a triad of hypercalcaemia, metabolic alkalosis, and renal insufficiency. The syndrome is now the third most common cause of hypercalcaemia because of the use of calcium carbonate in osteoporosis prophylaxis and treatment, and the syndrome should be considered in patients with hypercalcaemia, as it may result in permanent renal impairment.

    A calcium-sensing receptor mutation causing hypocalcemia disrupts a transmembrane salt bridge to activate β-arrestin-biased signaling.
    Sci Signal 2018 Feb 20;11(518). Epub 2018 Feb 20.
    Academic Endocrine Unit, Oxford Centre for Diabetes, Endocrinology and Metabolism, Radcliffe Department of Medicine, University of Oxford, Oxford OX3 7LJ, UK.
    The calcium-sensing receptor (CaSR) is a G protein-coupled receptor (GPCR) that signals through Gand Gto stimulate cytosolic calcium (Ca) and mitogen-activated protein kinase (MAPK) signaling to control extracellular calcium homeostasis. Studies of loss- and gain-of-functionmutations, which cause familial hypocalciuric hypercalcemia type 1 (FHH1) and autosomal dominant hypocalcemia type 1 (ADH1), respectively, have revealed that the CaSR signals in a biased manner. Thus, some mutations associated with FHH1 lead to signaling predominantly through the MAPK pathway, whereas mutations associated with ADH1 preferentially enhance Caresponses. Read More

    Managing hyperparathyroidism in hemodialysis: role of etelcalcetide.
    Int J Nephrol Renovasc Dis 2018 5;11:69-80. Epub 2018 Feb 5.
    Division of Nephrology, Hennepin County Medical Center, University of Minnesota, Minneapolis, MN.
    Secondary hyperparathyroidism (SHPT) is common in patients receiving maintenance hemodialysis and is associated with adverse outcomes. Currently, SHPT is managed by reducing circulating levels of phosphate with oral binders and parathyroid hormone (PTH) with vitamin D analogs and/or the calcimimetic cinacalcet. Etelcalcetide, a novel calcimimetic administered intravenously (IV) at the end of a hemodialysis treatment session, effectively reduces PTH in clinical trials when given thrice weekly. Read More

    Normocalcaemic primary hyperparathyroidism: a pragmatic approach.
    J Clin Pathol 2018 Feb 3. Epub 2018 Feb 3.
    Wolverhampton Endocrine and Diabetes Unit, New Cross Hospital, Wolverhampton, UK.
    It is well recognised that over the past three to four decades the incidence of asymptomatic primary hyperparathyroidism has increased significantly. However, more recently this pattern has further evolved into a presentation with normocalcaemia and raised parathyroid hormone (PTH) level without the presence of a recognised stimulus for its rise, in the form of vitamin D deficiency or renal impairment. A diagnostic label of normocalcaemic hyperparathyroidism (NPHPT) has been given to this phenotype and in most such individuals, the initial PTH measurement is driven by the presence of metabolic bone disease.

    Rare and changeable as a chameleon: paraneoplastic syndromes in renal cell carcinoma.
    World J Urol 2018 Feb 10. Epub 2018 Feb 10.
    Department of Urology, Eberhard Karls University Tübingen, Hoppe-Seyler-Straße 3, 72076, Tübingen, Germany.
    Introduction: Paraneoplastic syndromes (PNS) in renal cell carcinoma (RCC) are important to be recognized by the treating physician, because they may lead to diagnosis of underlying malignant disease. On the other hand, PNS may dominate the clinical picture and can hide the true disorder like a chameleon. When realized, a PNS can be used as a 'neoplastic tumour marker', especially in case of recurrence. Read More

    AP2? Mutations Impair Calcium-Sensing Receptor Trafficking and Signaling, and Show an Endosomal Pathway to Spatially Direct G-Protein Selectivity.
    Cell Rep 2018 Jan 28;22(4):1054-1066. Epub 2018 Jan 28.
    Academic Endocrine Unit, Radcliffe Department of Medicine, University of Oxford, Oxford, UK. Electronic address:
    Spatial control of G-protein-coupled receptor (GPCR) signaling, which is used by cells to translate complex information into distinct downstream responses, is achieved by using plasma membrane (PM) and endocytic-derived signaling pathways. The roles of the endomembrane in regulating such pleiotropic signaling via multiple G-protein pathways remain unknown. Here, we investigated the effects of disease-causing mutations of the adaptor protein-2 ? subunit (AP2?) on signaling by the class C GPCR calcium-sensing receptor (CaSR). Read More
