Visfatin (pre-B cell colonyenhancing factor) is a adipocytokine playing an important role in glucose homeostasis. High concentrations of visfatin are observed in obese people. Previous studies suggest that estimation of visfatin concentration could be a promising tool for predicting obesity or its metabolic consequences. The aim of the study was to evaluate the correlation between visfatin concentration, selected anthropometric parameters (BMI, WHR, BAI, VAI index) and biochem...

Objective: Smoking during pregnancy could have impact on steroidogenesis, with more marked changes in smokers carrying boys as well as in their newborns. The aim of study was compared steroid hormones between non-smokers, ex-smokers, which stop smoking in the beginning of pregnancy, and active smokers.Method: We focused on changes in steroidogenesis in the blood of mothers in their 37th week of pregnancy and in mixed cord blood from their newb...

Background: Patients with type 2 diabetes (T2DM) are generally known to have increased risk of various types of cancer. However, the studies addressing the association between T2DM and thyroid cancer are heterogeneous and inconclusive. The aim of our study was to evaluate the patients who have already undergone thyroid surgery with histologically confirmed results as the ‘gold standard’.Methods: A retrospective study in 102 patients (74 women a...

Background: Measurements of plasma metanephrines provide a sensitive test for diagnosis of pheochromocytoma/paraganglioma (PPGL). However, false positive results can pose a diagnostic dilemma for clinicians. The aim of the study was to determine whether commonly prescribed drugs with potential action on the sympathetic nervous system can falsely elevate plasma free normetanephrine, metanephrine and methoxytyramine.Methods: This retrospective study includ...

Introduction: Paragangliomas are rare neuroendocrine neoplasms arising from chromaffin cells in the sympathetic or parasympathetic neural paraganglia that may appear in many places throughout the body. These might be benign or malignant tumors. We report an interesting case of disseminated paraganglioma, the diagnosis of which began with the metastasis to the thyroid gland.Case presentation: A 69-year-old patient with a history of toxic multinodular goit...

Background: Although in most cases insulinomas are small and benign tumors, in about 4% they are malignant, mainly in course of inherited syndromes like MEN1, tubular sclerosis or neurofibromatosis type 1. While in case of benign tumors surgery is usually curative, the metastatic form brings difficulties in managing due to dissemination and the risk of recurring, life-threating, severe hypoglycemias. To elucidate the clinical differences between sporadic and MEN-1 linked insul...

Background: Although gastroenteropancreatic neuroendocrine tumors G3 (GEP-NET G3) and neuroendocrine cancers (GEP-NEC G3) are characterized in histopathological examination by Ki67>20% or >20 mitoses/10HPF their management and prognosis is substantially different. Despite the WHO introduces the novel well-differentiated neuroendocrine tumour of high grade (NET G3) classification in 2017 the clinical management of them is still challenging due to high NET G3 heterogenei...

Objectives: Fine needle aspiration biopsy (FNAB) together with ultrasonography is a necessary tool for diagnosis and follow up of thyroid nodules. Molecular testing is increasingly used mainly for indeterminate categories of the Bethesda System for Reporting Thyroid Cytopathology revised in 2017. Our aim was to introduce a routine molecular analysis of the main genetic causes of thyroid cancer.Methods: Since 2017 we have analyzed 1171 samples of patients...

Objectives: Molecular testing of fine-needle aspiration biopsy (FNAB) samples is increasingly used mainly for indeterminate categories of the Bethesda System for Reporting Thyroid Cytopathology. Our aim was to introduce a routine molecular analysis of the main genetic causes of thyroid cancer.Methods: In total, 1354 FNAB samples of thyroid nodules were analyzed. Testing procedures mainly in samples evaluated as Bethesda categories III and above were grad...

Background : Omentin, also known as intelectin-1, is a member of the family of adipose tissue-related hormones known as adipokines, that exert anti-inflammatory, anti-atherosclerotic, and cardiovascular protective effects. Omentin expression has been detected in adipocytes as well as in a variety of extra-adipose tissues, including the ovary. Interestingly, omentin expression in the pituitary has been shown to be regulated by pituitary hormones. These observations led us to in...
