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...

Introduction: Polycystic ovary syndrome (PCOS) is the most prevalent endocrinopathy among women during reproductive age. Using ESHRE/ASRM diagnosis of PCOS is considered when 2 of 3 criteria are present: polycystic ovary morphology (PCOM), oligo/anovulation (ANOV) and hyperandrogenism (HA). These criteria form four different phenotypes: A (ANOV, HA, PCOM), B (ANOV, HA), C (HA, PCOM) and D (ANOV, PCOM). Several studies have found differences in anthropometric, hormonal and meta...

Introduction: Polycystic ovarian syndrome (PCOS) is characterized by hyperandrogenism, chronic oligo-/anovulation and polycystic ovarian morphology. Hyperandrogenism is a key diagnostic feature of PCOS and according to ESHRE/ASRM criteria it can be clinical and/or biochemical. SPISE index (single-point insulin sensitivity estimator index) is a new indicator of insulin sensitivity and a predictor of abnormal glucose metabolism. The aim of the research was to analyse association...

Interindividual variations in tissue sensitivity to glucocorticoids (GC) have been partly attributed to polymorphisms in the glucocorticoid receptor (GR) gene. The aim of this study was to investigate whether BclI variant of the GR gene may contribute to metabolic abnormalities frequently present in patients with adrenal incidentaloma (AI). Biochemical tests and hormonal evaluation were performed in 106 consecutive women with AI. Non-diabetic patients underwent an ora...

Neuroendocrine tumors encompass a heterogeneous group of tumors arising from the diffuse neuroendocrine system. The incidence of NETs rises with age, with the peak after 65 years. However, all NETs observed in adults may be diagnosed in children too. There are a very few studies addressing NETs in young patients. This study summarizes clinical, histopatological and genetic characteristics of young patients with NETs. This is a retrospective study describing clinical, histopath...

Introduction: Although intensive, repeated and perennial, physical stress of training generally does not represent a health hazard to professional athletes. Adaptation to such stress is presumed on multiple levels, but still not fully defined. Our aim was to analyze specificities of hypothalamic-pituitary-adrenal (HPA) axis response and adaptation to physical stress in professional athletes.Subjects and methods: We exposed 55 professional male athletes t...

Introduction: Metformin and oral contraceptive pills (OCP) are the most commonly prescribed medications among women with polycystic ovary syndrome (PCOS). The aim of this study was to compare effects of pill containing cyproterone-acetate (CPA) and metformin (METF) in women with PCOS during six months of follow-up.Methods: Group of 60 women with PCOS diagnosed by ESHRE/ASRM criteria were divided into 3 subgroups (20 women each), which were treated with d...

To investigate the prevalence of SH and osteoporosis in female patients with unilateral AIs (UAIs) and bilateral AIs (BAIs).We enrolled 106 female patients, 68 (64.2%) with UAIs and 47 (35.8%) with BAIs. SH was diagnosed in the presence of serum cortisol levels after 2-day low-dose dexamethasone suppression test (LDDST) >50 nmol/l with at least one of the following parameter (midnight serum cortisol >208 nmol/L, 24-h urinary free cortisol >24...

Introduction: Calcitonin secreting neuroendocrine tumors (NET) are rare and not well recognized. Due to many similarities, it is sometimes difficult to differentiate them from medullary thyroid carcinoma (MTC), which can hamper choice of proper therapy. We investigated our group of patients with this type of NET in terms of diagnosis and biology.Patients and Methods: We analyzed 38 patients with calcitonin secreting NET (5% of all our patients with NET)....

Introduction: A link between diabetes and coronary heart disease is well-known. The aim of this study is to examine the influence of actual and retroactive diabetes regulation parameters (admission glycaemia and HbA1C value) on duration of hospital stay and clinical outcome of T2DM patients suffered from NSTEMI/STEMI.Material and methods: Cross sectional study involved 103 examinees with past history of T2DM actually hospitalised in CCU due to acute myoc...
