Discovery of a novel CASR mutation causing Familial Hypocalciuric Hypercalcemia in a Greek family

Efstathiadou Zoe , Kostoulas Charilaos , Rottstein Laurentana , Georgiou Ioannis , Kita Marina

Introduction: Familial hypocalciuric hypercalcemia (FHH) causes lifelong hypercalcemia, which, in general, is not associated with significant morbidity. FHH1, the most common type of the disease, is inherited in an autosomal dominant pattern and caused by inactivating mutations in the Calcium Sensing Receptor (CaSR) gene, located in chromosome 3. Inactivation of CaSR in parathyroid cells results in a shift of calcium set point to higher values with consequent...

Acute pancreatitis, caused by parathyroid gland adenoma: A case report

Augytė Ieva , Liolytė Simona , Šiomonienė Diana

Abstract: Parathyroid gland adenoma is benign, PTH-secreting tumour, which leads to primary hyperparathyroidism. Congenital hyperparathyroidism may occur without any other symptoms, on it’s own, but often is part of MEN1 or MEN2 syndromes. PTH activates osteoclasts, that resorbs calcium from bone and brings calcium to blood serum. Also PTH also induces calcium reabsorption from kidney tubules band and blocks excretion of phosphates. Long time PTH secreting adenoma shows n...

Denosumab in clinical practice: efficacy, complications and adherence

Sagar Rebecca , Rogers Emily , Chau Vincent , Bald Alexander , Potts Sarah , Cooke Heather , Orme Steve , Abbas Afroze

Background: Denosumab is a monoclonal antibody against RANK ligand used for the treatment of osteoporosis. Although clinical trials demonstrate that denosumab is highly effective at reducing fragility fractures in postmenopausal osteoporosis, there have been few studies looking at real world outcomes. Our primary aim was to assess the efficacy of denosumab in practice.Methods: We retrospectively formed a database of 257 patients seen in endocrinology out...

Transition of denosumab to primary care is enhanced by use of a transfer pack

Rogers Emily , Sagar Rebecca , Wong Jo Ann , Cooke Heather , Orme Steve , Abbas Afroze

Background: Denosumab, given 6 monthly as a subcutaneous injection, is well established as a treatment for osteoporosis. In the UK it is initiated in secondary care with most patients continuing with injections in primary care. Given concerns with hypocalcaemia and possible adverse effects on fracture risk due to abrupt cessation, robust monitoring in primary care is important. Our study compares two groups of patients on denosumab, one following a well-defined treatment pathw...

Vegan diet: a true danger in paediatrics

Lockhart Veronique , Giabicani Eloise

Veganism is spreading in western societies, as a new ‘healthy’ and ecological diet. But in children, it can lead to malnutrition, with damaging consequences in a still-developing organism. We report the case of a thirteen-month-old boy born at term with appropriate measurements and no medical history. He was kept at home by his mother, and his father was a senior executive. He was brought to the Hospital because of hypotonia and loss of walking ability. He didn’...

A rare case of cushing disease and hypophosphatasia

Preiato Valentina Lo , Zavatta Guido , Ribichini Danilo , Altieri Paola , Pelusi Carla , Pagotto Uberto

Cushing disease and hypophosphatasia are rare conditions that may be both responsible of an important impairment of bone metabolism with increased fracture risk. We reported for the first time a case of a 43-year-old woman that came at our attention for recent onset of alopecia and amenorrhea. At the anamnesis, she denied any past relevant events and no drug assumption. At the physical examination, she presented rubeosis and facies lunaris and central adipose distribution (wai...

Delta M Delta , Echin Monica Echin , Perel Cecilia , Loterstein Vanesa Lotersztein , Buzzolino N Buzzolino , Solari A Solari , Massoto B Masotto

Microdeletions or microduplications in the 22q11.2 region cause a variety of disorders, including DiGeorge syndrome (DGS; MIM 188400), velocardiofacial syndrome (VCFS; MIM 192430) and cat-eye syndrome (CES; MIM 115470). DGS and VCFS clinically overlap and are both caused by three million-base pair (Mb) deletions on the chromosome region 22q11.2, flanked by low copy number repeats (LCRs) labeled ‘A-D’. The most common deletion, present in 85% of individuals, extends f...
