Background: Disorders caused by impairments in the parathyroid hormone (PTH) signaling pathway are historically classified under the term pseudohypoparathyroidism (PHP), that encompasses rare, related but highly heterogeneous diseases with demonstrated (epi)genetic causes. The actual classification is based on the presence or absence of specific clinical and biochemical signs together with an in vivo response to exogenous PTH and the results of an in vitro as...

Background and aims: Vitamin D deficiency during the perinatal period has been hypothesized to increase risk for several psychiatric disorders in humans. As newborn vitamin D levels are entirely dependent on maternal vitamin D status, vitamin D deficiency in utero may leave the infant vulnerable to cognitive defects and behavioral problems. Few human studies have examined these associations with inconclusive results. We aimed to investigate the associations of maternal 25-hydr...

Mass Spectrometry coupled with liquid chromatography (HPLC-MS-MS) levels of 25-hydroxy vitamin D (25OHVitD) are associated with prognostic markers of Heart Failure

Saponaro Federica , Saba Alessandro , Frascarelli Sabina , Marcocci Claudio , Cetani Filomena , Passino Claudio , Zucchi Riccardo

Introduction and aims: Heart failure (HF) is a health problem with poor prognosis, despite many treatments available. Vitamin D is the pre-hormone of the active calcitriol (1,25(OH)2D3). It is involved in bone homeostasis, but recent studies suggest extraskeletal functions, including pleiotropic effects on cardiovascular system and a relationship between low levels of 25OHvitamin D and worse HF prognosis. The aims of the study were: 1) to define 25OH-D levels in the HF populat...

Introduction and design: Parathyroid carcinoma (PC) is a rare endocrine malignancy and the diagnosis is difficult. As the incidence seems to be increasing, we examined all cases diagnosed in our country during years 20002011 and compared the results to those of atypical parathyroid (AA; n=28) and parathyroid adenomas (A; n=72). All tissue specimens were re-examined.Results: In 20002011, 32 patients were diagnosed with PC in ...

Familial hypocalciuric hypercalcemia secondary to a novel mutation causing severe hypercalcemia

Shrikrishna Natasha , Mohamed Syuhada , Middleton Maeve , Wong Stephen

Introduction: Familial Hypocalciuric Hypercalcemia (FHH) is a benign autosomal dominant condition caused by an inactivating mutation on the gene coding for the Calcium Sensing Receptor (CASR). CASR plays a role in regulating parathyroid secretion and calcium metabolism. The majority of adults with FHH are asymptomatic. This is a case of three young brothers whose genetic tests shows two mutations in each of their CASR gene leading to hypercalcemia and varying symptoms.<p c...

Idiopathic infantile hypercalcemia: presenting in childhood, diagnosed in adulthood – case report

Silvestre Catarina , Paixao Raquel , Aragues Jose Maria , Guerra Silvia , Mascarenhas Mario

Introduction: Hypercalcemia can be caused by a variety of pathologies/factors. Vitamin D plays a central role in calcium homeostasis, where a tight control of its metabolism is necessary. Inadequate 24-hydroxylase-enzime (CYP24A1) activity leads to failure of 25-hydroxyvitamin and 1,25-dihydroxy-vitamin D3 inactivation, resulting in hypercalcemia.Case report: An asymptomatic, 22-year-old woman was admitted in an Endocrinology appointment for evaluation o...

Background: PHPT is often overlooked/underdiagnosed. Several strategies (biochemical markers alone or combined in complex algorithms) have been investigated to easily diagnose/screen PHPT, but PHPT diagnosis remains challenging at present, especially in asymptomatic patients. As serum calcium (Ca) and phosphorous (P) are inversely related in PHPT, the Ca/P ratio could be a good candidate tool for PHPT diagnosis. Surprisingly, no literature data on Ca/P ratio are available, des...

Background: Parathyroid hormone (PTH) is a key regulator of mineral metabolism, the homeostasis of calcium, phospate, vitamin D and bone turnover. Hypoparathyroidism is a rare disease characterized by hypocalceamia with inappropriately low plasma levels of PTH. Mean platelet volume (MPV) is the measure of platelet size. Increased MPV has been associated with cardiovascular risk.Objective: In our preliminary study, we aim to show that untreated hypoparath...

Clinical case of chronic calcific pancreatitis in a patient with parathyroid carcinoma caused primary hyperparathyroidism

Britvin Timur , Ignatyuk Vyacheslav , Kazarian Armine

Parathyroid carcinoma is a rare cause of primary hyperparathyroidism (PHPT) and is usually presented with severe hypercalcaemia and parathyroid hormone (PTH) elevation. Hypercalcaemia can lead to calcification of parenchymatous organs, including pancreas, and acute or chronic pancreatitis.Case report: A 46-year-old woman was admitted to the endocrine surgery department of our institution with severe weakness, appetite and weight loss (25 kg in a year), a...

The relationship between obesity and serum Vitamin B12, folic acid, vitamin D concentrations in obes adults: a retrospective study

Yagan Fidan Canan Celik , Olcum Gulcin Gungor , Kurtulus Duygu , Tugtekin Haci Bayram

Background: Obesity is associated with many diseases. e.g. cardiovascular diseases. The most common deficiency associated with obesity seems to be low concentrations of vitamin D that is associated with an increased risk of diabetes and other cardiovascular diseases. Low concentrations of vitamins are linked to accelerated atherosclerosis through increased oxidative stress. The purpose of this research was to investigate the association between obesity and vitamin B12(VB12), f...

Our cases of familial hypocalciuric hypercalcemia

Bayrak Muharrem , Cadirci Kenan , Carlioglu Ayse , Sevimli Hakan , Durmaz Senay

Familial hypocalciuric hypercalcemia is an inherited disease caused by inactivating heterozygous mutations in the gene encoding calcium-sensitive receptors, that affects calcium metabolism and generally follows a benign course. It must be also considered in the differential diagnosis of hyperparathyroidism. Six patients presenting to our internal diseases clinic between January, 2010, and June, 2015, were evaluated in terms of clinical and biochemical parameters. The youngest ...

The role of cinacalcet in a patient with persistent hypercalcaemia despite parathyroidectomy

Mlawa Gideon , Affam Dora , Silveira Maria

Introduction: Parathyroid adenoma is the commonest cause of primary hyperparathyroidism, but 10% of these adenomas can be ectopic, leading to persistent and recurrent hypercalcaemia.Case: We present a case of 82 years old man was admitted in June 2011 with increasesd confusion, slurred speech, poor balance (ataxia). He had no features of sepsis and no other focal neurology. His past medical history included constipation, dry eyes. He was on Aspirin, hypr...

Use of recombinant parathyroid hormone with significant improvement of debilitating hypocalcaemia and hypomagnesaemia

Panteliou Eleftheria , James Ajith , Hawkins Anna , Jones Stuart , Kwong Pandina , Gupta Dinesh , Razzak Yousaf , Casey Edel , Nikookam Khash

Primary hypoparathyroidism is a rare condition. Contrary to other endocrine deficiencies treated with hormone replacement, recombinant parathyroid hormone (PTH) is not currently licensed for its treatment in Europe. Emerging evidence of efficacy and safety of recombinant PTH in treating resistant hypoparathyroidism will hopefully provide a new tool in managing this challenging condition.This is the case of a 45 year-old woman presenting with gradually wo...

Bahadir Cigdem Tura , Bahadir Sinan

Objective: Dysarthria is a motor speech disorder resulting from impairment in strength, speed and coordination of neural and/or muscular structures that are related to respiration, voice and speech. They may be classified as motor neuron dysarthria, cerebellar dysarthria and extrapyramidal dysarthria (subdivided as hypokinetic and hyperkinetic). Patients with dysarthria are evaluated primarily by neurology specialists. Though, we present our case to emphasize that dysarthria m...
