Post-surgical hypoparathyroidism is most common cause of hypoparathyroidism develops after accidental damage to or removal of the parathyroid glands during surgery. Heart arrhythmias and fainting, even heart failure is reversible complications of hypoparathyroidism, due to low calcium levels. Long QT (LQT) interval may lead to syncope, cardiac arrest, or sudden death. The goal of hypoparathyrodisms treatment is to relieve symptoms and to normalize levels of calcium and phospho...

A pheochromocytoma is a rare, catecholamine-secreting tumor that may precipitate life-threatening hypertension. The tumor is malignant in 10% of cases. Although pheochromocytoma has classically been associated with von Hippel-Lindau (VHL) syndrome, multiple endocrine neoplasia type 2 (MEN 2), and neurofibromatosis type 1 (NF1) there are now 10 genes that have been identified as sites of mutations leading to pheochromocytoma.Method and materials A case re...

Acromegaly is chronic disease caused by hypersecretion of growth hormone (GH), most common caused by adenoma of pituitary gland. Cardiovascular risk, respiratory complication and malignancy are more common in this patients. Most often onset is between 30 to 50 years old, equally between gender. Therapy is almost always surgery, it can be combined with radiotherapy and gamma knife. Medicament therapy with somatostatin analogues, dopamine agonists and GH receptor antagonist. Goa...

Introduction: Increased levels of high-sensitivity C-reactive protein (hs-CRP) and interleukin 6 (IL-6) accelerates atherosclerosis and occurrence of cardiovascular complications in patients with type 2 diabetes (T2D). Intima-media thickness (IMT) is a surrogate marker of atherosclerosis in patients with T2D.Aim: The aim of the study was to evaluate the significance of determining inflammatory markers IL-6, hs-CRP and IMT, as atherosclerosis markers, dur...

Introduction: Merkel cell carcinoma is a rare and aggressive neuroendocrine skin cancer. It is characterized by a high rate of local recurrence after surgical resection as well as the occurrence of distant metastases. It mostly occurs in the elderly and the exact etiology is unknown. The most significant risk factors for its occurrence are exposure to ultraviolet light and the oncogenic effect of the Merkel cell polyoma virus.Aim: Demographic and clinica...

Premature ovarian failure (POF) is characterized by amenorrhea, hypergonadotropism and hypoestrogensm in women under 40 years. Sex steroids play an important role in maintaining bone mass and cessation of ovarian function results in significant bone loss.Objective: To evaluate bone mass density (BMD) and factors influencing it in women with POF.Design & methods: First group of 144 women with spontaneous POF (I), 39.7±7.6 y...

Aim: Functional neuroendocrine tumors (NETs) represent a specific diagnostic and therapeutic challenge. Hormonal clinical syndrome can severely complicate clinical picture and affect treatment. Functional pancreatic NETs have been extensively studied. Our aim was to analyze functional lung NETs in terms of clinical characteristics and survival.Materials and methods: We retrospectively analyzed data from 230 patients with lung NETs treated at our departme...

Paragangliomas (PGLs) and pheochromocytomas (PCCs) are rare neuroendocrine tumors that arise from chromaffin cells of the adrenal medulla and the sympathetic/parasympathetic neural ganglia, respectively. We retrospectively analyzed 82 patients (43 female and 38 males) predominantly with PGLs who were hospitalized between January 2002 and December 2022. Twenty one patients were lost to follow up. The median age at diagnosis was 47 years (11–75) and the mean tumor size was ...

Objectives: Women with polycystic ovary syndrome (PCOS) are at increased risk for cardiovascular disease. Aim of our study was to determine the frequency of cardiovascular risk factors using Framingham Scoring system (FSS) in PCOS and controls.Methods: FFS included age, value of cholesterol and HDL (mmol/L), smoking and systolic blood pressure (sysBP, mmHg). We also determined LDL (mmol/l), oxidized LDL (OxLDL, U/l) and triglycerides (mmol/l). We studied...

Introduction: Chromogranin A (CgA) is a major representative of the protein family named granins stored predominately in secretory granules of the diffuse neuroendocrine system. Circulating CgA serves as a biomarker of neuroendocrine tumors (NETs), but its increased plasma concentration is present in various cardiovascular, gastrointestinal, renal and inflammatory diseases. Intra-granular and/or extracellular proteolysis of CgA generates a variety of biologically active fragme...
