Aim: There is a significant link between the increased activity of estrogen and its metabolites in endometrial carcinogenesis. Polymorphisms of the gene involved in metabolism of estrogen can modulate risk for the development of endometrial cancer. CYP1B1 plays an important role in estrogen metabolism. In our study, the frequency of three CYP1B1 gene polymorphisms (4326 C> G, 4390 A> G and 355 G> T) were studied in obese and non-obese women with endometrio...

Introduction: Several population-based studies have shown that hyperinsulinemia and insulin resistance could be an independent predictive factor for development of coronary artery disease (CAD).Aim: The aim of this cross-sectional study was to analyze insulin secretion in patients with proven coronary artery disease.Methods: We have analyzed 151 consecutive patients (35–79 years old, men 68%, women 32%) referred for coronary a...

Somatostatinomas are rare neuroendocrine tumors of the pancreas and small intestine that can occur sporadically or in a syndromic form. Duodenal somatostatinomas are often associated with neurofibromatosis type1 (NF1). Their presenting features are mostly related to local effects of the tumor mass rather than functional clinical syndrome. Nesidioblastosis is extremely rare cause of persistant hyperinsulinemic hypoglycaemia in adults.We present a case of ...

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...

Background/aims: Gaucher disease (GD) is autosomal recessive lysosomal storage disorder caused by the deficiency of enzyme glucocerebrosidase (GCD) with consequent massive acumulation of lipid-laden macrophages in various tissues including liver. It has been shown that chronic diseases with liver involvement might cause IGF1 deficiency. The aim of the study was to assess the IGF1 system in adult patients with type 1 Gaucher disease with and without enzyme replacement therapy (...

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...

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...

Introduction: Chronic endogenous hypercortisolism in Cushing’s syndrome imposes a great clinical burden of comorbidities, some of which might persist even after disease remission. Our aim was to analyze factors that predict long-term comorbidities after surgical remission of Cushing’s disease (CD).Subjects and methods: We retrospectively analyzed 37 patents (91.9% females) aged 39.5±13.9 years (10-70) with diagnosed CD, treated in our inst...
