PurposeInferior petrosal sinus sampling (IPSS) is the gold standard test for the differentiation of pituitary Cushing disease from the ectopic ACTH syndrome (EAS). The measurement of prolactin during IPSS can be helpful to improve the accuracy of the procedure. We aimed to evaluate the effect of measuring prolactin levels as a predictor for the accuracy of IPSS procedure and evaluate its’ impact on the lateralization of adenoma.<p class="abstext...

Introduction: Vitamin D (Vit D) receptors have been shown in extra skeletal tissues. Vit D deficiency plays a role in the development of many malignant, chronic inflammatory, autoimmune and metabolic diseases. Our aim was to evaluate the effect of Vit D replacement therapy on insulin sensitivity, endothelial function and oxidative stress in Vit D deficient subjects.Material-method: Serum 25(OH) D levels of 74 volunteer-healthy subjects (22.7±2.7) we...

Aim: Peak bone mass is a major determinant of osteoporosis risk in later life. It is under strong genetic control; In the present study, we investigated the relationship between polymorphisms in the gene encoding the vitamin D receptor (VDR) (FokI and Bsm 1) and bone mineral density (BMD), bone mineral content (BMC), and markers of bone turnover in 106 young Turkish women (19–23 yrs) and 100 man (19–23 yrs). Methods: BMD and BMC were measured by dual-energy X-ray abs...
