Introduction: We present an unusual case of hypophosphataemia with diagnostic dilemma.Case: 43-year-old female presented with 4-year history of muscle weakness, fatigue, bony pains, and limb paraesthesia. There was no background of fractures or iron deficiency. Her medications included amitriptyline and probiotics. She was a non-smoker and teetotaller; mother was short stature, father normal height. There was no family h...

Introduction: Resistance to thyroid hormone (RTH) is an autosomal dominant condition with mutation of thyroid hormone receptor beta (THR-β) gene. We present 2 cases with unusual thyroid picture posing challenge to diagnosis.Case 1: 31-year-old lady presented with 6-month history of anxiety, tremors, insomnia and headache. She suffered from asthma and had a family history of hyperthyroidism. On examination, she was o...

Introduction: Congenital nephrotic syndrome (CNS) is defined as heavy proteinuria starting within three months after birth. It affects approximately 1 to 3 per 100 000 children worldwide. The classical form is the Finnish type, caused by mutations in the nephrin gene. Approximately 50 percent of all nephrotic patients have low total thyroxine (T4) concentrations resulting from urinary losses of T4-binding globulin (TBG) and other thyroid hormone-binding protei...

Objective: To determine the frequency of polycystic ovary syndrome (PCOS) in women with prediabetes compared to control women.Methods: Digital screening and tele-interviews remotely excluded 3218 out of 3465 consecutive women applied for routine check-up. In-person assessments were performed on 247 women, excluding 49. Final analyses included 198 premenopausal women without endocrine disorders (other than prediabetes and PCOS) or conditions affecting gon...

İntroduction: Polycystic ovary syndrome (PCOS) is associated with risk of cardiovascular disease (CVD). Endocan is potential immunoinflammatory and endothelial dysfunction marker that may be linked to CVD. This study aimed to evaluate the risk of CVD in PCOS patients and to identify the novel biomarker for CVD risk.Material and methods: We analyzed 52 premenopausal women with PCOS and 59 healthy controls. Clinical, biochemical parameters and endoca...

Introduction: The criteria defining the threshold size of adrenal incidentaloma (AI) are >1 cm diameter. However, data about AI ≤1 cm diameter is scant. The aim of this study is to evaluate function of adrenal masses ≤1 cm and to compare them with adrenal masses >1 cm as well as to understand the possible utility of determining salivary cortisol in diagnosis of SCS in patients with AI.Method: The study included 137 consecutive patient...

Visfatin is a newly discovered adipocyte hormone. Recent studies showed a possible relationship between diabetes mellitus and visfatin level. But the effect of visfatin on the insulin resistance was not well understood. The aim of the present study was to explore the relation of visfatin with insulin resistance in patients with prediabetes and diabetes.We included a total of 128 persons in the study and of these 128 persons, 36 were diabetic, 69 were pre...

Aim: Overt hypothyroidism affects mostly women with an increased prevalence in individuals by age. Hypothyroidism is associated with accelerated atherosclerotic cardiovascular diseases, possibly caused by the higher incidence of hyperlipidemia, insulin resistance, hypertension which all are associated to hypothyroidism. Heart-type fatty acid binding protein (H-FABP) is specific for cardiomyocytes and a sensitive marker of myocardial injury. The purpose of this study is examini...

Aim: Several studies suggest a link between vitamin D and obesity. Vitamin D may play a role in obesity. Ghrelin is an orexigenic peptide which induces obesity by central and peripheral mechanisms. Administration of ghrelin promotes food intake and decreased fat utilisation in rodents. Ghrelin levels are decreased in obese individuals.The aim of this study was to evaluate the relationship between vitamin D status and ghrelin levels.Methods: All subjects ...

Background: Primary hyperparathyroidism (PHPT) is one of the most common endocrine diseases. Parathyroid carcinoma, a rare entity, comprises a small percentage of patients with hyperparathyroidism and represents 0.005% of all cancers and <1% of cases of PHPT.Material and methods: Patients was diagnosed at the Endocrinology Department of Diskapi Yildirim Beyazit Training and Research Hospital between 2010 and 2016. Ultrasound and 99mTc-Sestamibi confi...
