Background: Antidiuretic analogue desmopressin was tested in its intranasal form in renal colic, with variable effects.Aims: We evaluated the effects of sublingual desmopressin in lithiasic renal colic, alone or combined with a non-steroidal antiinflammatory drug (NSAID).Materials and methods: Our prospective single-blind study included an initial number of 371 patients with lithiasic renal colic randomized as follows: group NSAID ...

The Na+/I− symporter (NIS), a glycoprotein expressed at the basolateral plasma membrane of thyroid epithelial cells, mediates active I− uptake for the biosynthesis of thyroid hormones and radioiodide transport for diagnosis and treatment in thyroid cancer. Our cloning of the NIS cDNA and generation of anti-NIS antibodies provided the basis to investigate the decrease in I− transport in thyroid cancer relative to hea...

Introduction: Over the past few years the clinical relevance of serum uric acid level has changed. The elevated serum uric acid level not only impairs the joints and the kidney function but it is also linked with an increased risk of cardivascular diseases. The aim of our study was to examine how bones are affected (change of bone mineral density (BMD), bone metabolism parameters, serum 25-hydroxyvitamin D levels and frequency of fractures) by elevated serum uric acid level.</...

Objective: According to recent studies, impaired secretion of GH is a frequent finding after ischaemic stroke. The aim of our study was to compare various available GH stimulation tests in post-stroke patients.Design: Seventeen patients were included in the study (12 males; mean age: 60.5 years; mean BMI, 27.7 kg/m2) with a mean 19.6 (±7.3) months after stroke. For screening, glucagon and small dose (0.15 μg/kg) GHRH-arginine (sdGHRH...

Introduction: Lactose intolerance itself is linked with lower peak bone mass (PBM) and with decreased bone mineral density (BMD) which may decrease further with lactose intolerance associated comorbidities. The aim of our study was to examine how bone metabolic parameters are affected (change of bone metabolism markers, BMD and frequency of fractures) in lactose intolerance which was accompanied by previously diagnosed hyperlipidemia or by hypothyroidism.<p class="abstext"...

Introduction: Polycystic ovary syndrome (PCOS), lactase deficiency, nephrolithisasis and thyroid diseases are considered endemic. The aim of our study was to evaluate which of the above-mentioned diseases affect the most the bone metabolic parameters, bone mineral density (BMD) and the prevalence of bone fractures in fertile aged women.Materials and methods: A total of 92 fertile aged women (32.6±5.2 years) were divided into four groups (23 in each)...

Loss-of-function mutations in the TSH receptor (TSHR) gene are one of the most common known causes of congenital hypothyroidism (CH). While heterozygous mutations result in nonautoimmune isolated hyperthyrotropinemia, homozygous and compound heterozygous mutations may cause overt CH of various severity depending on the localization and type of the mutations.In our study we performed the systematic genetic analysis of the TSHR gene of a cohort of 85 Hunga...

The sodium/iodide transporter (NIS) mediates active I− uptake in thyroid, lactating breast, salivary gland, and stomach epithelial cells. NIS-mediated I− transport is electrogenic with a 2:1 Na+:I− stoichiometry, i.e. when NIS activity is measured electrophysiologically in NIS-expressing oocytes, inward positive currents are recorded upon addition of I− or other anions that are NIS substrates. Howev...

The optimal treatment of hyperthyroidism in Graves’ disease is still an unresolved question. Hyperthyroidism recurs in 50% of patients after discontinuation of antithyroid therapy. In this retrospective study, Graves’ patients investigated in the endocrine unit of Pecs University between December 2004 and October 2006 were enrolled (68 women, 22 men, age 47 (15–79) years). Antithyroid drug therapy was applied for a minimum of one year and the treatment was withd...

Introduction: The autoimmune polyglandular syndrome is a complex, heterogeneous disease in which autoimmune diseases of endocrine and non-endocrine organs can occur. There are 4 subgroups: the early-onset APS I develops due to the mutation of the gene AIRE and characterized by the presence of Addison’s disease (AD), mucocutan candidiasis and hypoparathyroidism; the APS II is defined by the appearance of AD and autoimmune thyroid diseases (AITDs) and/or diabetes mellitus; ...
