Objectives: Women with polycystic ovary syndrome (PCOS) are at increased risk for cardiovascular disease. Aim of our study was to determine the frequency of cardiovascular risk factors using Framingham Scoring system (FSS) in PCOS and controls.Methods: FFS included age, value of cholesterol and HDL (mmol/L), smoking and systolic blood pressure (sysBP, mmHg). We also determined LDL (mmol/l), oxidized LDL (OxLDL, U/l) and triglycerides (mmol/l). We studied...

Introduction: Cortisol has important roles in the regulation of body composition and hypercortisolaemia have major impact on body fat distribution. The aim of this study was to analyze differences in adipose tissue distribution in women with Cushing’s disease and Cushing’s syndrome due to adrenal adenoma.Method: We evaluated 12 women with Cushing’s syndrome, six with ACTH secreting pituitary adenomas (Group A) and six with adrenal adenomas...

Introduction: Luteinizning hormone (LH/hCG) responsiveness has been documented in both normal and pathological adrenal glands, but it is unclear whether chronic exposure to LH could affect adrenal function by increasing LH receptor (LHR) expression.Subjects and methods: We studied 12 postmenopausal women with previously documented adrenal tumor. All patients underwent standard hormonal testing for assessment of tumor functionality. Then hCG test was perf...

Adrenocortical carcinoma (ACC) is rare malignancy associated with poor prognosis. The aim of this study was to present clinical characteristics and survival of patients with ACC and to analyse the effect of prognostic factors on survival.We retrospectively analysed 69 patients (46 female and 23 males) with pathologically confirmed ACC who were treated in our hospital between January 2005 and December 2015. The median age at diagnosis was 51,0 years (rang...

Introduction: Chromogranin A (CgA) is a major representative of the protein family named granins stored predominately in secretory granules of the diffuse neuroendocrine system. Circulating CgA serves as a biomarker of neuroendocrine tumors (NETs), but its increased plasma concentration is present in various cardiovascular, gastrointestinal, renal and inflammatory diseases. Intra-granular and/or extracellular proteolysis of CgA generates a variety of biologically active fragme...

Background: Several polymorphisms of glucocorticoid receptor (GR) gene, including BclI, N363S and ER22/23EK, which may have an influence on glucocorticoid sensitivity, have been reported. BclI and N363S polymorphisms have been associated with clinical characteristics of increased and ER22/23EK of decreased glucocorticoid (GC) effects. On the other hand, metabolic syndrome has been described in patients with adrenal incidentalomas.Objective ...

A 34 year-old female patient was admitted to the hospital because of a large nodule in the left thyroid lobe and elevated calcitonine level. A large encapsulated tumor was found and total thyroidectomy with left neck dissection was performed. Pathohistology revealed medullary and papillary carcinoma separate from each other in tumor tissue but mixed in regional lymph nodes. Papillary component was dominant in thyroid tissue but not in lymph nodes. Both calcitonine and thyroglo...

Neuroendocrine tumours (NETs) have a unique ability to produce and secrete a variety of biogen amines and peptide hormones. They arise from multipotential stem cells, which differentiate during tumorigenesis into specific cell lines. Some of these tumours are functional, producing characteristic clinical syndromes. We present a female patient incidentally discovered to have diffuse liver metastases of neuroendocrine tumour of unknown primary origin. She was free of symptoms at...

Introduction: Hormonal syndromes are significant cause of morbidity in patients with neuroendocrine tumors (NET), requiring special treatment, rarely completely efficient. Effect on mortality is also presumed. Our aim was to investigate epidemiological characteristics of NET with hormonal production in our group of patients.Patients and methods: We analyzed 822 patients with NET of various primary tumor sites, treated at our department during period of 2...

IntroductionHypogonadism is a potential manifestation of many chronic diseases including cancer, presumably related to their severity. Since novel anti-cancer treatments have significantly increased survival rates of affected patients, issue of hypogonadism becomes more significant, given the importance of issues like quality of life and potential for reproduction. The aim of our study was to analyze gonadal axis function in male patients with neuroendoc...
