Leptin is a circulating hormone produced primarily by the adipose tissue, which controls food intake and energy homeostasis. Important peripheral actions of leptin involve inhibition of insulin biosynthesis and secretion in pancreatic ß-cells. In turn, insulin stimulates leptin secretion from adipose tissue, establishing a hormonal regulatory feedback loop: ‘adipo-insular axis’. The aim of our study was to determine the interrelations between leptin, insulin/ins...

Pheochromocytomas, tumors derived from adrenal medulla, are characterized by a polymorphic clinical picture dominated by paroxysmal hypertension. Between the clinical, laboratory and pathology data, discordances are frequently seen.Patients and Methods: Thirty five cases of pheochromocytoma and paraganglioma (10 men) with adrenal tumors and hypertension were confirmed with pheochromocytoma. They were aged 53.68±12.75 years (36–75), while the tu...

Introduction: Thyroid tissue may be found anywhere along the course of thyroglossal duct. Sublingual thyroid is a rare type of ectopic thyroid tissue resulting from failure of the embryonic development and migration of the thyroid gland to its normal pre-laryngeal site, reaching between genio-hioid and mylohyiod muscles. In most cases, hypothyroidism develops due to inadequate hormon production. Hypothyroidism may produce pituitary enlargement secondary to thyrotroph hyperplas...

Breast cancer (BC) is the most common type of cancer and the leading cause of cancer-related death in women worldwide. A considerable number of these long-term survivors may therefore have an elevated risk of developing a second primary malignancy (SPM). Thyroid cancer (TC) is the most prevalent endocrine malignancy among women. Epidemiologic studies have indicated that patients with BC have a higher risk of developing TC as an SPM, and vice versa, than would be expected in th...

Introduction: Hyperglycaemia occurs frequently in catecholamine-secreting tumours due to insulin suppression or induced insulin resistance. These changes can be reversible postoperatory (postOp).Objective: Our study aims to establish the impact of surgery in patients with catecholamine-secreting tumours upon glucose metabolism disorders, as well as the predictive factors for postOp diabetes-free patients.Methods: We retrospectively...

Background: There are only few reports regarding the role of serum galectin-3 (Gal-3) as an early biochemical marker in thyroid carcinoma.Aim: To evaluate the potential overexpression of Gal-3 in sera from patients with confirmed diagnosis of papillary thyroid carcinoma (PTC).Patients and methods: We retrospectively investigated serum Gal-3 in 40 patients referred to the surgical department for thyroidectomy. Sera were collected be...

Myasthenia gravis (MG) and autoimmune thyroid diseases (AITD) may coexist and influence one another clinical expression. The opportunity of thymectomy in this association is controversial, since not all the studies have proven its efficacy. We report eight patients (one man and seven women) diagnosed with AITD (Graves’ disease (GD) – five cases, Hashimoto’s thyroiditis (HT) – three cases) and MG. The AITD diagnosis preceded (two cases), followed (three case...

Introduction: Pheochromocytomas are rarely malignant, defined by the presence of cathecholamine – producing metastases. Malignant pheochromocytoma responds poorly to chemotherapy and radiotherapy. 131I-MIBG therapy can be used to prolong survival, with minor side effects.Case: A 45-years old woman known with malignant pheochromocytoma, with a long medical history, first came to our clinic in July 2012. Her diagnosis was suspected in 1999 ...

In pheochromocytoma, intense lypolitic activity may lead to altered lipid profile, which can reverse after tumour removal.Aim: In this study, we evaluated before and at 3 months after surgery for a cathecholamine secreting tumour, a group of 19 patients diagnosed with pheochromocytoma (17) or paraganglioma (2).Patients and methods: 13 women and 6 men, aged 53.68±12.75 years (36–75), presented with a clinical picture of pa...

Primary hyperparathyroidism (PHPT) is a relatively frequent problem in clinical endocrine practice. Minimally invasive parathyroid surgery is the treatment of choice but requires precise preoperatory localization. The most commonly investigation methods are ultrasonography and scintigraphy, but they are not always diagnostic. PTH assay of the aspirate from an ultrasound-guided fine-needle aspiration (USFNA) may confirm the location of pathological parathyroid tissue. The aim o...
