Menopause is associated with multiple health and metabolic consequences resulting from the decrease in estrogens level. Women at postmenopausal age are burdened with a higher risk of cardiovascular diseases, and the main cause of mortality in this group is ischemic heart disease. Estrogen deficiency is related, among other things, with frequent occurrence of dislipidemia, cessation of the beneficial effect of estrogens on the vascular wall, increase in body weight characterized by unfavourable redistribution of fatty tissue, with an increased amount of visceral fat and reduction of so-called non-fatty body mass...

INTRODUCTION: A 45,X/46,XY karyotype in women with Turner syndrome (TS) is very rare. The presence of a Y chromosome in the karyotype causes phenotypic differences and increased risk for neoplastic disease, compared to TS-women with other karyotypes. Our study addresses an issue: non-genital phenotypic differences between TS-patients with a Y-chromosome of their karyotype and TS-women without it. MATERIAL AND METHODS: Results from patient history/physical examinations of the head and neck of eight TS-women and the 45,X/46,XY karyotype were compared with those observed in 164 TS-women and 30 controls...

INTRODUCTION: The pituitary adenomas secreting thyrotropin (TSH) are considered the rarest type of the hormonally active pituitary tumour. In spite of that, many cases are described in the literature. On the other hand, the observations of the co-expression of TSH with other pituitary hormones (mostly with growth hormone - GH) and "silent" expression of TSH in clinically nonfunctioning pituitary adenomas (CNFPA) are rather scarce. MATERIAL AND METHODS: Among 93 examined pituitary adenomas, 22 of them are diagnosed as active acromegaly and 71 as clinically nonfunctioning pituitary adenomas (CNFPA)...

INTRODUCTION: Melatonin exerts its biological role acting mainly via G protein-coupled membrane MT₁ and MT2 receptors. To determine whether a response of oxytocinergic neurons to different concentrations of melatonin is mediated through membrane MT₁ and/or MT₂ receptors, the effect of melatonin receptors antagonists, i.e. luzindole (a non-selective antagonist of both MT₁ and MT₂ receptors) and 4-phenyl-2-propionamidotetralin (4-P-PDOT - a selective antagonist of MT₂ receptor), on melatonin-dependent oxytocin secretion from the rat hypothalamo-neurohypophysial (H-N) system, has been studied both in vitro and in vivo...

INTRODUCTION: Irisin, cleaved and secreted part of the transmembrane protein FNDC5, is a recently discovered adipo-myokine said to have a significant influence on body metabolism. Changes in thyrometabolic state may also alter serum irisin level. Since already reported data are not fully consistent, the aim of the present research is to evaluate the time-dependent changes in serum irisin level in patients affected by overt hypothyroidism. MATERIAL AND METHODS: Study involved 36 subjects - two groups of 12 patients with long-lasting (AITD) and short-term (TC) overt hypothyroidism, and control group (CG) of 12 subjects, matched for age and gender...

INTRODUCTION: Irisin, a recently identified myokine, is associated with increased energy expenditure and has a potential role in obesity. Therefore, we investigated circulating irisin levels in morbidly obese patients undergoing sleeve gastrectomy (SG). MATERIAL AND METHODS: Thirty morbidly obese patients undergoing SG and 30 healthy subjects were included. All participants were evaluated at baseline and again at 3 months post-SG. Body weight and height, the lipid profile, and plasma glucose, HbA1c, insulin and irisin levels were measured at each visit...

INTRODUCTION: Late-night salivary cortisol is a frequently used and easily implemented diagnostically valuable test for the diagnosis of overt Cushing's syndrome. The use of late-night salivary cortisol in the diagnosis of subclinical Cushing's syndrome is somewhat controversial. In this study, we aimed to determine the diagnostic value of late-night salivary cortisol in diagnosing subclinical Cushing's syndrome and compared it with 24-hour urinary free cortisol levels (UFC). MATERIAL AND METHOD: The study consisted of 33 cases of subclinical Cushing's syndrome, 59 cases of non-functioning adrenal adenoma and 41 control subjects...

Ig-G4 related disease (IgG4RD) is a heterogeneous disorder with multi-organ involvement recognised as a separate entity at the start of this century only. It is currently one of the hottest areas of clinical and translational research across specialties. Thyroid involvement in IgG4RD is rare, believed to occur in less than 4% of cases, may be isolated or may be associated with other organ involvement. As of today Riedel's thyroiditis, fibrosing variant of Hashimoto's thyroiditis, and few patients of Graves' orbitopathy represent the types of IgG4-related thyroid disease (IgG4RTD)...

INTRODUCTION: Numerous investigations, and especially in vitro studies, indicate that TGF-β1 may act as an important regulator of bone remodelling. Thus, it could be expected that disturbances of this cytokine production observed by several researchers might play a role in the mechanism leading to the development of osteoporosis in girls with anorexia nervosa (AN). The aim of the study was to determine whether 1) girls with AN exhibited a relationship between TGF-β1 and bone metabolism (as assessed based on serum OC and CTx concentrations) and 2) whether OPG and sRANKL might modify the possible relationship between TGF-β1 and bone metabolism...

Cushing's syndrome (CS) is defined as a constellation of clinical signs and symptoms occurring due to hypercortisolism. Cortisol excess may be endogenous or exogenous. The most common cause of CS is glucocorticoid therapy with supraphysiological (higher than in the case of substitution) doses used in various diseases (e.g. autoimmune). One possible CS cause is ectopic (extra-pituitary) ACTH secretion (EAS) by benign or malignant tumours. Since its first description in 1963, EAS aetiology has changed, i.e. as well as small cell lung cancer (SCLC), higher incidence in other malignancies has been reported...

The paper presents a case study of a transsexual patient who underwent a voice pitch elevation surgery performed in Poland for the first time. The human voice is a reflection of the working of hormones and human psyche. This fact is of particular importance in transsexualism, a disorder consisting in incongruence between the individual's biological sex and their identified gender. For many transsexual people, especially of the MTF (male to female) type, who have undergone hormonal and surgical sex change, the voice still presents a major problem, causing difficulties in everyday life...

Adrenocortical carcinoma is associated with a low cure rate and a high recurrence rate. The prognosis is poor, and at diagnosis 30-40% of cases are already metastatic. The current therapeutic options (surgical resection, followed by adjuvant mitotane treatment +/- chemotherapy) are limited, and the results remain unsatisfactory. Key molecular events that contribute to formation of adrenocortical cancer are IGF2 overexpression, TP53-inactivating mutations, and constitutive activation of the Wnt/b-catenin signalling pathway via activating mutations of the b-catenin gene...

The growth hormone (GH) and insulin-like growth factor (IGF) system plays an important role in the regulation of cell proliferation, differentiation, apoptosis, and angiogenesis. In terms of cell cycle regulation, the GH-IGF system induces signalling pathways for cell growth that compete with other signalling systems that result in cell death; thus the final effect of these opposed forces is critical for normal and abnormal cell growth. The association of the GH-IGF system with carcinogenesis has long been hypothesised, mainly based on in vitro studies and the use of a variety of animal models of human cancer, and also on epidemiological and clinical evidence in humans...

INTRODUCTION: Hypocalcaemia is a common postoperative complication, both after the resection of parathyroid adenoma associated with primary hyperparathyroidism and after total thyroidectomy due to thyroid cancer or nodular goitre. For a few years, in patients with postoperative hypoparathyroidism and severe hypocalcaemia, who cannot discontinue intravenous calcium preparations even with the use of high vitamin D doses, attempts have been made to add recombinant human parathormone (rhPTH) to the treatment schedule...
