A higher incidence of nodular goitre and less differentiated types of thyroid carcinoma have been observed in iodine deficient regions. North-Eastern Poland was an area with a moderate deficiency of iodine until the introduction of the mandatory salt iodination in 1997 (30±10 mg KJ/kg NaCl). The aim of our study was to compare the incidence of goitre, thyroid carcinoma and urine excretion of iodine in the inhabitants of the North-Eastern Region of Poland in 1997 and 2005....

Ghrelin is an endogenous ligand of the GH secretagogue receptor. The influence of ghrelin on different organs has been studied recently e.g. in the regulation of pituitary hormone release, regulation of energy homeostasis, glucose metabolism and insulin secretion, cell proliferation and reproductive function.The etiology of PCOS has not been firmly explained, althought several pathways have been implicated – the regulatory pathways of steroid hormon...

Isolated hypogonadotropic hypogonadism (IHH) is caused by impaired gonadoliberin (GnRH) gene regulation, synthesis or secretion of GnRH. Genetic factors of more than 50% of the IHH are still unknown. One the most common types of IHH is the Kallmann syndrome (KS) associated with anosmia or hyposmia. In view of technological progress and new possibilities for detecting changes in human genome a comprehensive targeted analysis using next-generation sequencing (NGS) was carried ou...

Introduction: Thyroid nodules may be detected in up to 67% of the adult population and constitute big diagnostic challenge. Presurgical differentiation of follicular lesions between follicular adenoma (FA) and follicular thyroid carcinoma (FTC) is particularly difficult. Commercially available gene panels cover only a few, selected mutations to help in discrimination between FA and FTC. The aim of this study was to comprehensively assess the genetic background of thyroid folli...

Introduction: Vitamin D is postulated to play a significant role in the immune system modulation and its deficiency has been reported in some autoimmune disorders. Polymorphisms of different vitamin D-related genes, among them vitamin D receptor gene (VDR), could either be a risk factor for autoimmune diseases. Therefore the aim of the study was to assess the association between VDR Cdx2 (rs11568820) polymorphism and autoimmune thyroid disease (AITD) among th...

Introduction: The number of thyroid cancer diagnosis has increased worldwide. However, its diagnosis, particularly in a case of follicular cancer (FTC), may be challenging. New markers of malignancy are intensively searched for.Case description: A 29-year-old female was referred for subtotal thyroidectomy in 2006 due to a nodule in the right lobe. The histopathological examination revealed follicular adenoma (FA). During endocrinological follow-up, in 20...

Fc Receptor-like (FCRL) genes play a role in the immune system by encoding proteins that function as receptors on the surface of immune cells. Peripheral blood B cells, which are positive for FCRL3 and FCRL4, are rarely found in healthy individuals. In previous studies overexpression of FCRL4 was observed in patients with Graves’ disease (GD) but without association with thyroid peroxidase (TPOAb) or thyroglobulin (TgAb) antibodies. Nonetheless, the clinical significance ...

Introduction: 2-[18F]FDG PET/CT, commonly used for neoplastic lesions detection, also allows assessment of the severity of the inflammatory processes. Moreover, glucose uptake in spleen and bone marrow may be a useful biomarker of systemic inflammation. Patients with Cushing syndrome demonstrate many metabolic changes involving muscles and fat tissue. Some mechanisms are known, but their relationship to glucose metabolism is not well investigated. Our study aimed to correlate ...

Differentiated thyroid cancer (DTC) is the most common malignant neoplasm arising from the thyroid parenchymal cells. DTC incidence is steadily increasing worldwide and there are approximately 1700 new cases/per year in Poland. The biopsy with subsequent thyroid resection plays a central role in the diagnosis and treatment of this malignancy. After surgery, radioactive iodine (RAI) treatment is recommended to eradicate potential residual disease and improve prognosis. Due to t...

Background: The gradual increase in the detection rate of adrenal incidentalomas makes them a common clinical problem. The vast majority of them are benign adrenocortical adenomas. Nevertheless every patient with adrenal incidentaloma requires performing number of tests to exclude pheochromocytoma, autonomous cortisol secretion, adrenal carcinoma and primary hyperaldosteronism. Evaluation of whether adrenal incidentalomas are malignant or functional and continuing patient foll...
