A 25-year-old female, referred because of left hemianopsy, weight gain, fatigue, muscle weakness, and secondary amenorrhea. Physical examination revealed overt Cushingoid features and left temporal hemianopsy. Previously the diagnosis of pituitary macroadenoma (MRI) with suprasellar, infrasellar, and right parasellar propagation was made in regional hospital. Laboratory results showed moderate hypercalcemia with hypophosphatemia and hypercalciuria with inappropriately normal P...

Objectives: Besides well known increased adrenal androgen production, an enhanced peripheral cortisol metabolism was also observed in polycystic ovary syndrome (PCOS). This could induce a compensatory rise of ACTH secretion, tending to maintain normal plasma cortisol concentration at the expense of adrenal androgen excess. On the other hand, obesity is associated with a hyperactivity of the hypothalamic–pituitary–adrenal (HPA) axis and impaired androgen balance. In t...

Objectives: It is well known that polycystic ovary syndrome (PCOS) can promote metabolic syndrome (MetSy) and consequently cardiovascular diseases (CVD). In this study we compared indices of MetSy and 10-year cardiovascular risk (CVR10) based on Framingham risk scoring system (FRSS) in young obese PCOS women and healthy obese controls.Methods: We studied 25 obese women with PCOS (mean age: 29.55±4.6 years, mean BMI: 31.8±4.4 kg/m<sup...

Neuroendocrine lung tumors represent approximately 20% of all lung tumors. They range from low-grade well-differentiated NETs and well-differentiated neuroendocrine carcinomas (typical and atypical carcinoids) to aggressive poorly differentiated small-cell and large-cell neuroendocrine carcinomas. They can develop different clinical syndromes due to ectopic hormone secretion.We analyzed 178 patients with neuroendocrine tumors (age range: 17–79 years...

Pancreatic neuroendocrine tumors (PETs) occurs in approximately 1 per 100 000 people per year and account for only 1–2% of all pancreatic tumors. Most of them are hormonally active, while about 30% secrete no detectable hormons and are discovered due to a tumor mass effect.Material and methods: We analysed 178 patients with neuroendocrine tumors (NETs) treated at our department in the last five years. The diagnosis was made by pathohistological exam...

Objectives: Insulin resistance and hyperinsulinaemia are implicated in the pathogenesis of the polycystic ovary syndrome (PCOS) in the majority of the cases. Adiponectin is adipose tissue-specific protein and its correlation with insulin resistance is well established. The aim of the study was to access the correlation between adiponectin and anthropometric and metabolic parameters in a group of women with PCOS.Methods: Thirty-one women with PCOS (age: 2...

Mutation Y791F of RET protooncogene is a well known mutation so far described in families with FMTC and familial pheochromocytoma in one family. It activates the receptor in a monomeric form. Here we present eight unrelated families with the same mutation but different fenotype expression.Patients and methods: In last 20 years, we analyzed 216 patients with MTC (age range: 3–75 years, 45.0 mean). Genetic testing for mutation in RET pro...

We describe a 52-year-old woman, with acromegaly, clival chondroid chordoma, meningioma and lung carcinoid. There was no family history of MEN-1. She was diagnosed as acromegaly in 2000. Radiological evaluation (MRI) revealed pituitary tumor, however, another infiltration of scull base was detected which invaded sphenoidal and ethmoidal sinuses, lamina cribroza and bilateral orbit walls. Pituitary tumor was completely removed and the reduction of extra-sellar mass was performe...

The diagnosis of adult growth hormone deficiency (GHD) in patients with pituitary disease relies predominantly on provocative tests of GH secretion. The incidence of GHD in treated acromegalic patients has not been fully documented. Therefore, the aim of the present study was to elucidate GH response to insulin-induced hypoglycaemia (ITT, 0.15 IU/kg i.v.) in a cohort of 10 patients with acromegly considered cured solely by transsphenoidal surgery (6 females and 4 males, mean a...

Single nucleotide polymorphisms in the glucocorticoid receptor (GR) gene influence tissue sensitivity of GR. Several studies have shown different effects of BclI GR polymorphism on body composition and metabolic parameters. The objective of this study was to explore the effect of BclI GR polymorphism on the body composition and glucose metabolism. Biochemical tests and hormonal evaluation were performed in 106 consecutive women with adrenal incidentalomas (AI...
