The most common cause of a mass lesion in the sella is pituitary adenoma. Some parasellar lesions may be cystic and sometimes may mimic the clinical and radiological features of pituitary adenoma. A 36 year-old woman was admitted to the hospital because of headache for five years and amenorrhoea for five months. Magnetic resonance (MR) imaging of the pituitary gland showed sellar mass lesion characterized by high signal intensity on T1 and T2-weighted images. Endocrinological ...

Aim: There is strong evidence regarding vitamin D being a risk factor for Type 2 Diabetes Mellitus (T2DM). In this study, we aimed to investigate the effects of vitamin D on advanced glycation end-products in prediabetic and type 2 diabetic patients with vitamin D deficiency.Methods: Forty type 2 diabetic patients, 40 prediabetic patients and 40 healthy controls with the levels of vitamin D <20 ng/ml were included in the study. All three groups were ...

Objective: Hyperprolactinemia has been reported to be associated with endothelial dysfunction, abnormalities of carbohydrate metabolism and insulin sensitivity. The aim of this study was to evaluate carbohydrate metabolism and endothelial function of our patients in outpatient clinics.Material and methods: In this cross-sectional study, currently or previously treated 87 hyperprolactinemic patients with PRL-secreting adenoma (fifty four with microadenoma...

Aim: The most common clinical presentation of primary hyperparathyroidism (PHPT) is asymptomatıc and it is diagnosed incidentally without developing complications.In our study, we aimed to examine the characteristics of participants with primary hyperparathyroidism and the relationship between bone mineral density (BMD) and hypercalciuria.Methods: Consecutive 191 normocalciuric (24-h urinary calcium<400 mg/day) patients with PHPT (51±13 yea...

Aim: Clinical presentation of primary hyperparathyroidism (PHPT) differs between populations. In this study, we aimed to examine bone mineral density (BMD) and bone metabolism parameters in newly diagnosed and untreated PHPT patients in a single endocrine center in İstanbul, Turkey.Methods: Consecutive 256 PHPT patients (50.7±14 years, F/M:205/51) and 89 healthy controls (38.8±10 years, F/M:67/22) were included in the study. Serum calcium...

Objective: Hyperprolactinemia is reported to be associated with impaired glucose metabolism, and low-grade inflammation. There is some data regarding increased oxidative stress- particularly protein oxidation in the conditions like metabolic syndrome or diabetes, but not in hyperprolactinemic subjects in the literature. We aimed to investigate advanced oxidation protein product (AOPP) levels-an established marker of protein oxidation and antioxidant thiol levels in hyperprolac...
