Background and objectives: Diabetes is estimated to affect more than half a billion people worldwide, of which approximately 9.5 million live in Turkey. Currently, glucoSemeasurements are made with invasive techniques (eg finger puncture or interstitial glucose sensors) that can negatively affect monitoring. In addition, since glucose results cannot be seen by physicians/nurses in real time, treatment decisions are delayed and diabetes control becomes difficult. As a group of ...

Objective: The aim of this study is to determine serum concentrations of adiponectin (ApN), leptin and ghrelin in different stages of anorexia nervosa (AN) and to evaluate their relationships between biochemical, hormonal and anthropometric parameters.Materials and methods: The study is composed of four groups. Group 1: Treatment-naïve patients with a recent diagnosis of AN (n: 19), Group 2: The weight recovered (10% increase in body weight c...

Introduction: We have reported a case of breast carcinoma complicated by diabetes insipidus due to pituitary metastasis.Case: A 47 years old woman had been referred our clinic with the symptoms of polyuria, polydypsia, weight loss, and fatigue. She had a diagnosis of breast carcinoma for six years, underwent radically mastectomy, chemotherapy and radiotherapy, subsequently. Vertebral metastasis was detected and local radiotherapy was performed six months...

Introduction: Thyrotropin-secreting pituitary adenomas (TSHomas) are a rare cause of hyperthyroidism and represent <1% of all pituitary adenomas. The majority of TSHomas (70%) secrete TSH alone, while mixed adenomas are not infrequent.Design: Herein, we reported the findings of six patients with TSHoma (mean age 44 yr, 4 female, 2 male). Mean TSH value was 15.1 mIU/L (3.3–38.0) who were followed-up in our department.Result...

A 41-year-old woman was admitted with headache and hypertension. She described worsening of headaches in the last 2 months. On physical examination blood pressure was 150/90 mmHg, and grade 1 hypertensive retinopathy was present. Her sister died at the age of 24 due to pancreas neuroendocrine tumour and her mother was followed up with multiple pancreatic cysts. Abdomen MRI revealed a 6 cm phaeochromocytoma lesion on the right surrenal and multiple cysts in the pancreas, kidney...

Clinical spectrum of phaeochromocytoma syndromes are very heterogeneous. Sometimes life threatening hypertensive attacks may be the presenting symptom or the clinical picture may be subtle that a nonspecific symptom like fatigue can lead to diagnosis. We herein present two phaeochromocytoma cases with distinct clinical features.Case 1: A 20-year-old female patient admitted to emergency department with blurred vision and headache. She experienced headache...

Oncogenic osteomalacia is a rare paraneoplastic syndrome, which can be associated with phosphaturic mesenchymal tumor or non-mesenchymal tumour. This tumour produces fibroblast growth factor 23 (FGF-23) that leads to subsequent hypophosphataemic osteomalacia. We, hereby present a patient with oncogenic osteomalasia who is misdiagnosed as ankylosing spondylitis. A 54-year old man with weakness, severe arthralgia involving pelvis, hip joints and lower extremities referred to the...

Objectives: Subclinical hypothyroidism (SH) is characterized by normal serum free T4 (FT4), free T3 (FT3) levels and increased serum TSH levels. Endothelial dysfunction that is accepted an early step of the atherosclerosis, has been reported in patients with subclinical hypothyroidism. The aim of this study was to eveluate endothelial functions and the effect of L-thyroxine (L-T4) therapy on e...

Introduction: Fibroblast growth factor (FGF)-23 is a peptid, released from bone tissue and osteogenic cells. Phosphatonins regulate phosphate homeostasis in some phosphate wasting disorders such as X-linked hypophosphatemia, otozomal dominant hypophosphatemic rickets, and tumor-induced osteomalacia.FGF-23 is a possible phosphatonin: it regulates phosphate homeostasis by PTH independent actions.Objective: In the present study, we ai...

Introduction: In recent years, interferon (IFN) is used in treatment of chronic hepatitis and the studies about the side effects of IFN therapy are increasing.Objective: We aimed to investigate the effects of IFN therapy on glucose metabolism.Materials and methods: Study group was consisted with 30 patients who were diagnosed as chronic hepatitis. Sixteen of 30 were chronic hepatitis B and 14 were chronic hepatitis C. Diagnose was ...
