The Fibroblast Growth Factor 23 (FGF23) gene provides instructions for making a protein called FGF23. This protein is necessary in regulating the phosphate levels within the body. We present a case of an adult Caucasian man with persistent hypophosphatemia due to mutation in ENPP1.Case History: A 34 years old male presented with intermittent muscle pain, cramps and headaches. He also noticed episodic breathlessness and irritability. He had no hi...

The co-existence of thyrotropin (TSH) and growth hormone (GH) secreting pituitary adenoma is exceedingly rare. Less than 15 cases having been reported.Case report: A 75 years’ old man presented with new-onset atrial fibrillation. He had high FT4 with normal TSH. His ultrasound scan of the neck showed a solitary nodule. He had ablation twice and was started on bisoprolol and anticoagulant. He had an MRI scan for headaches and this showed a pituitary ...

Background: Von Hippel-Lindau disease (VHL) is an autosomal dominant disease, characterized by haemangioblastomas of the retina and CNS, renal cell carcinomas (RCC) and renal cysts, pheochromocytomas, pancreatic neuroendocrine tumors and cysts, and endolymphatic sac tumors. VHL is associated with a germline mutation of the VHL tumor suppressor gene on the short arm of chromosome 3. The type-1 disease is caused by mutations, leading to severe disruption of protein acti...

Objectives: The frequency of Cushing’s disease (CD), ACTH independent Cushing’s syndrome (CS) and autonomous cortisol secretion (ACS) in patients with obesity is not well known and the results of the studies are heterogeneous. Therefore, in the present study, we aimed to assess the frequency of CD, CS, and ACS among patients with obesity.Methods: In this study, 813 consecutive patients [683 female, mean age 46.47±14.23-year-old, mean BMI 3...

Objective: Despite the high sensitivity of TRAb measured by modern assay methods, some patients with Graves’ disease (GD) may still have normal TRAb levels. Therefore, the purpose of this study was to determine the clinical utility of TRAb measured by a third generation assay method, and to determine it’s relationship with clinical and laboratory parameters in Turkish patients with GD.Methods: In this study, 328 consecutive treatment-naive pati...

Introduction: Current studies suggest that fractalkine (FKN) could be a pathogenic factor associated with adipocyte dysfunction and type 2 diabetes (T2DM) and have shown that FKN serum levels are increased in T2DM patients. The aim of this study was determined as evaluating the change of FKN levels that will occur with oral glucose tolerance test (OGTT).Methods: The study included 67 patients to whom OGTT was applied. The patients with the history of dia...

Introduction: Certain sensory system functions are affected somehow in acromegaly, however auditory complications have not been identified in detail yet. It is possible that widespread changes in acromegaly may also affect auditory system. We aimed to determine the changes involving auditory system in cases with acromegaly.Methods/design: Otological examination of 41 cases with acromegaly (active n=22, inactive n=19) were compared with ...

Background: Recurrent middle ear disease may lead to poor growth or may suggest an underlying diagnosis associated with short stature. The aim of the study was to describe stature in a cohort of girls attending a paediatric ENT service.Methods: Height and weight was measured in all girls attending ENT clinics over an 8 week period (n=83). A mid-parental height (MPH) was calculated from reported parental heights. Th...

Introduction: The aim of this study was to validate the American Thyroid Association (ATA) risk of recurrence staging system (2009).Methods: Retrospective analysed 300 adult (239 women, 61 men) differentiated thyroid cancer patients followed for a median of 57 months (range 38–97).Results: ATA risk stratification of patients according to the system 54.7% low-risk, 39.7% moderate risk, and 5.7% were in the high risk group. The ...

Introduction: Parathormone (PTH) is one of the major regulator of the bone and mineral metabolism. Elevated PTH levels in patients with primary and secondary hyperparathyroidism is thought to have negative effects on the cardiovascular system. In our study, we aimed to investigate a possible relationship between plasma PTH levels and coronary atherosclerosis.Methods: Fourty-two men and 35 women, a total of 77 patients were included the study who admitted...
