[Paraffin oil injecions due to bigorexia may cause hypercalcaemia].

Ugeskr Laeger 2018 Nov;180(48)

Paraffin oil injections may cause severe hypercalcaemia, likely due to development of granulomas at injection sites, activating 1,25 dihydroxyvitamin D and increasing calcium uptake from gut, kidney and bone. This is a case report of a 39-year-old male with severe hypercalcaemia and renal failure due to paraffin oil injections. He was treated with prednisolone (25-50 mg daily), but the disease recurred the next two summers probably due to erroneous vitamin D supplement and sun exposure. Read More

Primary hyperparathyroidism.

Best Pract Res Clin Endocrinol Metab 2018 Sep 28. Epub 2018 Sep 28.

Division of Endocrinology, College of Physicians and Surgeons, Columbia University, New York, NY, USA. Electronic address:

Primary hyperparathyroidism (PHPT), the most common cause of hypercalcemia, is most often identified in postmenopausal women with hypercalcemia and parathyroid hormone (PTH) levels that are either frankly elevated or inappropriately normal. The clinical presentation of PHPT includes three phenotypes: target organ involvement of the renal and skeletal systems; mild asymptomatic hypercalcemia; and more recently, high PTH levels in the context of persistently normal albumin-corrected and ionized serum calcium values. The factors that determine which of these three clinical presentations is more likely to predominate in a given country include the extent to which biochemical screening is employed, the prevalence of vitamin D deficiency, and whether a medical center or practitioner tends to routinely measure PTH levels in the evaluation of low bone density or frank osteoporosis.

Molecular pathogenesis of parathyroid tumours.

Best Pract Res Clin Endocrinol Metab 2018 Nov 20. Epub 2018 Nov 20.

Fondazione IRCCS Casa Sollievo della Sofferenza Hospital, Division of Medical Genetics, Italy. Electronic address:

Parathyroid tumors represent an elusive endocrine neoplasia, which lead to primary hyperparathyroidism, pHPT, a common endocrine calcium disorder characterized by hypercalcemia and normal-high parathormone secretion. Parathyroid tumours are benign adenomas or multiple glands hyperplasia in the vast majority (>99% of cases), while malignant neoplasms are rare (less than 1%). Despite pHPT is a common disorder, our knowledge about the genetic predisposition and molecular pathophysiology is limited to the familial syndromic forms of parathyroid tumour, that, however, represent not more than the 10% of all the cases; instead, the pathophysiology of sporadic forms remains an open field, although data about epigenetic mechanisms or private genes have been supposed.

External Quality Assessment of 24,25-Dihydroxyvitamin D (24,25(OH)D) Assays.

J Steroid Biochem Mol Biol 2018 Nov 23. Epub 2018 Nov 23.

National Institutes of Health (NIH) Office of Dietary Supplements (ODS), Bethesda, MD, 20892-7517, USA.

The discovery that mutations of the CYP24A1 gene are a cause of idiopathic infantile hypercalcemia (IIH) has revived interest in measuring serum 24,25(OH)D. Several studies have also suggested that a high 25-hydroxyvitamin D(25-OHD):24,25(OH)D ratio might provide additional diagnostic information in the investigation of vitamin D deficiency. Measurement of 24,25(OH)D is necessarily restricted to laboratories with mass spectrometry methods although cross reactivity of the metabolite in immunoassays for 25-OHD is a potential cause of misleading results.

Understanding the Bone in Cancer Metastasis.

J Bone Miner Res 2018 Dec 26;33(12):2099-2113. Epub 2018 Nov 26.

Departments of Cell Biology and Physiology, Washington University School of Medicine, St. Louis, MO, USA.

The bone is the third most common site of metastasis for a wide range of solid tumors including lung, breast, prostate, colorectal, thyroid, gynecologic, and melanoma, with 70% of metastatic prostate and breast cancer patients harboring bone metastasis. Unfortunately, once cancer spreads to the bone, it is rarely cured and is associated with a wide range of morbidities including pain, increased risk of fracture, and hypercalcemia. This fact has driven experts in the fields of bone and cancer biology to study the bone, and has revealed that there is a great deal that each can teach the other. Read More

Living kidney donation from people at risk of nephrolithiasis, with a focus on the genetic forms.

Urolithiasis 2018 Nov 23. Epub 2018 Nov 23.

UOC Nefrologia, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy.

Deciding whether to accept a donor with nephrolithiasis is a multifaceted task because of the challenge of finding enough suitable donors while at the same time ensuring the safety of both donors and recipients. Until not long ago, donors with a history of renal stones or with stones emerging during screening on imaging were not considered ideal, but recent guidelines have adopted less stringent criteria for potential donors at risk of stones. This review goes through the problems that need to be approached to arrive at a wise clinical decision, balancing the safety of donors and recipients with the need to expand the organ pool.

Endocrine Research Unit, San Francisco Veterans Affairs Health Care System, Department of Medicine, University of California, San Francisco, United States. Electronic address:

Familial hypocalciuric hypercalcemia (FHH) causes hypercalcemia by three genetic mechanisms: inactivating mutations in the calcium-sensing receptor, the G-protein subunit α, or adaptor-related protein complex 2, sigma 1 subunit. While hypercalcemia in other conditions causes significant morbidity and mortality, FHH generally follows a benign course. Failure to diagnose FHH can result in unwarranted treatment or surgery for the mistaken diagnosis of primary hyperparathyroidism (PHPT), given the significant overlap of biochemical features.

The calcium-sensing receptor in physiology and in calcitropic and noncalcitropic diseases.

Nat Rev Endocrinol 2018 Nov 15. Epub 2018 Nov 15.

Academic Endocrine Unit, Radcliffe Department of Medicine, University of Oxford, Oxford, UK.

The Ca-sensing receptor (CaSR) is a dimeric family C G protein-coupled receptor that is expressed in calcitropic tissues such as the parathyroid glands and the kidneys and signals via G proteins and β-arrestin. The CaSR has a pivotal role in bone and mineral metabolism, as it regulates parathyroid hormone secretion, urinary Ca excretion, skeletal development and lactation. The importance of the CaSR for these calcitropic processes is highlighted by loss-of-function and gain-of-function CaSR mutations that cause familial hypocalciuric hypercalcaemia and autosomal dominant hypocalcaemia, respectively, and also by the fact that alterations in parathyroid CaSR expression contribute to the pathogenesis of primary and secondary hyperparathyroidism.

This is a case report of a patient who developed severe, irreversible hypocalcemia after receiving one dose of pamidronate 90 mg for hypercalcemia of malignancy. Hypocalcemia is a known risk of bisphosphonate treatments, but the incidence of severe hypocalcemia is rare, and the risk factors are well established. However, in the treatment of hypercalcemia of malignancy, the treatment objective is to reduce the elevated serum calcium level, and the bisphosphonate is usually given as one time dose only.

From the Department of Medicine, Brigham and Women's Hospital and Harvard Medical School (J.E.M., N.R.C., I.-M.L., W.C., S.S.B., S.M., H.G., D.G., T.C., D.D., G.F., C.R., V.B., E.L.G., W.C.W., J.E.B.), and the Departments of Epidemiology (J.E.M., N.R.C., I.-M.L., W.C.W., J.E.B.) and Nutrition (E.L.G., W.C.W.), Harvard T.H. Chan School of Public Health - all in Boston.

Background: It is unclear whether supplementation with vitamin D reduces the risk of cancer or cardiovascular disease, and data from randomized trials are limited.

Methods: We conducted a nationwide, randomized, placebo-controlled trial, with a two-by-two factorial design, of vitamin D (cholecalciferol) at a dose of 2000 IU per day and marine n-3 (also called omega-3) fatty acids at a dose of 1 g per day for the prevention of cancer and cardiovascular disease among men 50 years of age or older and women 55 years of age or older in the United States. Primary end points were invasive cancer of any type and major cardiovascular events (a composite of myocardial infarction, stroke, or death from cardiovascular causes). Read More

Objective: Molecular diagnosis is a useful diagnostic tool in calcium metabolism disorders. The calcium-sensing receptor (CaSR) is known to play a central role in the regulation of extracellular calcium homeostasis. We performed clinical, biochemical and genetic characterization of sequence anomalies in this receptor in a cohort of 130 individuals from 82 families with suspected alterations in the CASR gene, one of the largest series described.

A Rare Case of Primary Hyperparathyroidism Caused by a Giant Solitary Parathyroid Adenoma.

Am J Case Rep 2018 Nov 8;19:1334-1337. Epub 2018 Nov 8.

Fourth Surgical Department, Aristotle University of Thessaloniki, General Hospital "G. Papanikolaou", Thessaloniki, Greece.

BACKGROUND Solitary parathyroid adenomas are the leading cause of primary hyperparathyroidism in 0% to 85% of cases. Diagnosis of parathyroid adenoma is based on typical clinical presentation of hypercalcemia, biochemical profile, and modern imaging studies. The purpose of this article is to present the diagnostic and therapeutic approach used for a 73-year-old female patient with a giant parathyroid adenoma measuring 5×2. Read More
