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...

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 and aims: Autoimmune thyroiditis represent a state predisposed for the development of hypothyroidism. It is known that subclinical and overt hypothyroidism are important risk factors associated with the development and progression of heart failure. These effects are due to the changes in the structure and function of the cardiac muscle, as well as the overall cardiac mechanics. The aim of our study was to examine the influence of autoimmune thyroiditis (Hashimoto ...

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...

Introduction: Increased adrenal androgen production is present in 20–60% of women with polycistic ovary syndrome (PCOS). Possible mechanism is not clarified yet and could be related to altered hypothalamic-pituitary-adrenal-axis (HPA) activity or a consequence of adrencortical steroidogenic abnormalities. The aim of the study was to assess HPA sensitivity in PCOS women using different doses of dexamethasone.Methods: We analyzed 359 women with PCOS d...
