Introduction: Bardet-Biedl Syndrome (BBS) is an autosomal recessive disease and one of the most common causes of syndromic obesity. An excessive weight usually appears at an early age and affects almost 90% of patients. Mutations in BBS genes have been found to disrupt the function of the cilia, leading to disturbances of transduction satiety and hunger signals in hypothalamus and increased adipogenesis in the fat tissue.Methods: We present a case series...

Introduction: Type B insulin resistance syndrome is an autoimmune disorder characterized by the production of autoantibodies against the insulin receptor. It leads to glucose metabolism disorders, extreme insulin resistance, hyperandrogenism and is associated with other features of autoimmunity.Case report: A 27-year-old man, with a 2-years history of psoriasis, was admitted to our Department because of loss of weight (20 kg in 1 year) and fatigue. He al...

Polycystic ovary syndrome (PCOS) and type 1 diabetes (T1DM) are accompanied by increased risk of atherosclerosis. A higher prevalence of PCOS in T1DM patients has been reported. Brachial artery flow-mediated dilatation (FMD) and intima media thickness of common carotid artery (IMT) are used to detect an early endothelial dysfunction.The aim of our study was to examine IMT and FMD in T1DM women with PCOS. We also estimated the relation of IMT and FMD to c...

Proto-oncogene RET encodes a receptor tyrosine kinase. Germline point mutations of RET result in development of multiple endocrine neoplasia, type 2 (MEN 2). MEN 2 phenotype is correlated with intragene localization of germline mutation. The disease has three main subtypes, MEN 2A, MEN 2B and FMTC. Each of subtypes is associated with high risk of medullary thyroid cancer, MEN 2A and MEN 2B with 50% risk of pheochromocytoma, MEN 2A with 15–30% risk of primary hyperparathyr...

GEPNETs are rare tumors of very variable biology, particularly proliferative potential. Improved knowledge of the clinical course of disease may lead to proper identification of patients requiring more aggressive approach.Aim: i) characteristics of GEP-NET patients of the Endocrinology Department, University Hospital in Krakow, Poland; ii) identification of factors influencing their 5-year survival.Material and methods: Study inclu...

Cancer registers are important tools in improving the knowledge of epidemiology of rare malignancies, such as gastro-entero-pancreatic neuroendocrine tumors.Aim: To assess the epidemiology of GEPNETs in Krakow and Krakow district area between January 2007 and December 2011.Material and methods: To assess the epidemiology of GEPNETs in Krakow area a register was created, based on independent sources of information. 88 patients (49 f...

Abstract Identification of factors influencing survival of the gastro-entero-pancreatic neuroendocrine tumors patients may improve their management by better selection of subjects requiring more closed follow-up and more aggressive therapeutic approach.Aim: To assess factors influencing survival of GEPNET patients livingin Krakow and Krakow district area.Material and methods: The data from GEPNETs register run in t...

Introduction: Polycystic ovary syndrome (PCOS) is associated with an increased risk of insulin resistance. The involvement of microRNAs, small, non-coding molecules, in regulation of metabolic processes has been investigated. The role of miR-27a and miR-320 in regulation of glucose metabolism is documented. The aim of the study was to assess the level of circulating miR-27a and miR-320 in PCOS patients and to investigate its relationship with glucose metabolism.<p class="a...

Anorexia nervosa (AN) is an eating disorder, resulting in sustained low weight. In AN, similarly to syndromes of lipodystrophy, one observes the significant loss of the adipose tissue. In lipodystrophies, despite the lack of subcutaneous adipose tissue, insulin resistance is observed. Adipose tissue is known as a source of a variety of bioactive peptides, known as adipocytokines. The aim of the present study was to examine the plasma concentration of adipocytokines in relation...

Visfatin is a newly discovered protein secreted by adipose tissue, which is suggested to play a role in pathogenesis of insulin resistance. Polycystic ovary syndrome (PCOS) is heterogeneous disorder, where insulin resistance might be involved in the development of endocrine and metabolic abnormalities. The aim of the present study was to asses the relation between serum visfatin and insulin sensitivity and markers of hyperandrogenism in a lean and obese PCOS patients. The stud...
