Aim: Several studies suggested that there is a relationship between serum levels of IGF1 or their polymorhisms and some cancer types. The genetic polymorphism in the region of IGF promoter region which is composed of cytosine–adenine repeats, affects the promoter activity. It is suggested that serum IGF1 levels are inversely associated with the length of CA repeats. There are studies reporting that the carriers of the CA 19 allele are more likely to develop some cancer ty...

Less than 1% cases of acromegaly is caused by ectopic secretion of growth hormone releasing hormone (GHRH).A 25-year-old woman was admitted to the hospital, with iron deficiency anemia, acromegaly and a 6×6 cm mass in infrahepatic location near to the pancreatic head. Sellar magnetic resonance (MR) imaging indicated pituitary enlargement without obvious evidence of a pituitary adenoma. The patients underwent abdominal exploration. Histopathological ...

Introduction: We designed a retrospective study to investigate the clinical presentation, laboratory and pathological findings of 14 patients with ACTH-independent macronodular adrenal hyperplasia.Materials and methods: Diagnose of Cushing’ s syndrome was confirmed by biochemical tests, adrenal hyperplasia was confirmed by pathological examination in all patients.Results: No supression was observed in overnight, low and high d...

The aim of this study is to evaluate endothelial function in patients with primary hyperparathyroidism (pHT) during the preoperative hypercalcemic and postoperative normocalcemic periods and to determine whether intron 4a/b polymorphism of eNOS gene influences endothelial function. Forty-one patients with pHT (28 women, 12 men; age: 48.4±11.6 years, serum calcium: 11.4±1.0 mg/dl, parathyroid hormone: 373.3±394.5 pg/ml) who fulfilled the criteria for parathyroid ...
