Introduction: Familial hypocalciuric hypercalcemia (FHH) is an autosomal-dominant genetic disease caused by an inactivating mutation in the gene encoding the calcium sensing receptor (CaSR). The loss of function leads to increased circulating level of PTH and subsequent hypercalcemia.Case report: 20-year-old male patient referred to our center with hypercalcemia which was found after the syncope. His serum calcium level was 11.7 mg/dl and the phosphorus ...

Introduction: Pituitary tumorous hyperplasia with hyperprolactinemia has been described as a rare presentation of primary hypothyroidism. The loss of thyroxin feedback inhibition in primary hypothyroidism causes overproduction of thyrotropin-releasing-hormone (TRH), which results in secondary pituitary enlargement. TRH has a weak stimulatory effect on the lactotroph cells of the pituitary, so a mild to moderate increase in prolactin (PRL) levels is expected. This report descri...

Aim: Ghrelin plays an important role in the stimulation of food intake and long-term regulation of body weight. In present study we investigate the long term effect of exenatide treatment on serum fasting ghrelin levels in patients with type 2 diabetes mellitus.Methods: Type 2 diabetic patients who were using metformin with and without the other oral antihiperglycemic drugs on a stable dose for at least 3 months were enrolled in the study. Body mass inde...

Introduction: Hemangiopericytomas (HPC) are rare vascular tumours that may be associated with hypoglycaemia. Here we report a case of HPC with multiple metastases, accompanying severe recurrent hypoglycaemia due to the combination of different aetiologies.Case report: A 21 year-old woman was hospitalised due to loss of consciousness. The patient has been diagnosed as HPC by tibia mass biopsy 1 year ago. Tumour embolization was made several times. On admi...

Introduction: Subacute thyroiditis (SAT) has been reported after COVID-19 infection and SARS-CoV-2 vaccination. SAT has a mild and self-limiting course. This is the first reported case of thyroid storm following the SARS-CoV-2 vaccineCase: A 32-year-old female patient had mild anterior neck pain, fatigue, tremor 2 weeks after being administered with the second dose of COVID-19 mRNA vaccine BNT162b2 (Pfizer–BioNTech). Initial biochemical investigatio...

GAPO syndrome (OMIM 230740) is a rare, multiple congenital anomalies syndrome characterized by Growth retardation, Alopecia, Pseudoanodontia and Ocular manifestations. Syndrome caused by anthrax toxin receptor 1 (ANTXR1) gene (NM_032208.2) mutation leading to deficiency of an enzyme involved in the metabolism and breakdown of extracellular matrix (ECM). Disease show parental consanguinity, autosomal recessive inheritance and since first description in 1947 a total of 38 patien...

Aim: Fibroblast growth factor (FGF) 21 is a hormone which plays an important role in metabolic diseases such as diabetes, obesity and dyslipidemia. In this study; we aimed to investigate the serum total and bioactive FGF21 levels in patients with gestational diabetes mellitus (GDM) and compared with healthy pregnant controls.Material and Methods: A two-step screening method and Carpenter and Coustan criteria were used in the diagnosis of...

Aim: Olfaction and gustation have great importance on feeding behavior and food preferences. Recent published data suggests that olfaction and taste functions are modulated in response to changing levels of various molecules such as ghrelin and leptin which are play important roles on feeding and energy balance. We aimed to investigate the olfaction and taste functions in obese female patients and the association between serum ghrelin and leptin levels compared with healthy co...

Aim: Ghrelin plays an important role in stimulation of food intake and long-term regulation of body weight. In present study we aimed to investigate the effect of exenatide treatment on serum ghrelin levels in patients with type 2 diabetes.Methods: Fourteen women patients with type 2 diabetes treated with metformin and exenatide were enrolled in the study. A mixed meal test was applied to the patients while they were using their daily medications. Serum ...

Aim: To assess the contribution of macroprolactin (macroPRL) to high serum prolactin (PRL) levels and association of prolactin and macroprolactin levels with thyroid status and thyroid autoimmunity during pregnancy.Methods: Pregnant women (n=138) who had undergone a thyroid-stimulating hormone (TSH) screening during the first trimester of pregnancy enrolled in the study. Serum prolactin, macroprolactin, TSH, FT4, FT3, and thyroid autoantibodies ...
