Introduction: The gut hormone peptide YY 3-36 (PYY3-36) is secreted postprandially from intestinal L-cells to signal satiety. Peripheral administration of PYY3-36 suppresses food intake in rodents and humans. PYY3-36-based drugs are therefore promising anti-obesity treatments. It has been proposed that circulating PYY3-36 supresses appetite via the Y2 receptor (Y2R) in the hypothalamic arcuate nucleus (ARC). The vagus nerve, the majo...

Objectives: Broad insight into metabolic disturbances caused by diabetes ketoacidosis (DKA) and persist after pH normalization.Methods: Three groups of children with type 1 diabetes were recruited: after an episode of DKA (DKA, n=20), with established diabetes (EDM, n=10) and with new onset diabetes without DKA (NDM, n=10). EDM and NDM groups were matched to the DKA one for sex and age. Serum samples were collected at three tim...

Isolated hypogonadotropic hypogonadism (IHH) is known to decrease bone mineral density due to lack of pubertal surge of gonadotropins and deficiency of sex steroid hormone. Gonadal steroid hormones imbalance affects body composition. Nineteen Caucasian men, 22–48 year old (mean±S.D. 33±7.65) diagnosed with IHH (8 normosmic, 11 anosmic or hyposmic) were enrolled into the study. 14 patients were on hormone replacement therapy (HRT), 5 patients were ...

Introduction: Inferior petrosal sinus sampling (IPSS) is considered to be the gold standard for confirming the source of ACTH secretion in patients with Cushing’s syndrome (CS). Prolactin measurement during IPSS can improve diagnostic accuracy and reduces false negative responses.Patients and methods: 56 patients with ACTH-dependent CS were included (45 F/11 M, mean age 43.6±10.8 years and 90.1% Cushing’s disease) diagnosed since 2000. IPS...

Introduction: Follicular tumours of the thyroid gland include benign follicular adenomas, follicular carcinomas and the follicular variant of papillary carcinoma. Although, molecular markers are a promising area of research to differentiate thyroid neoplasms, there is ample room for improvement in the research and clinical applications in this field. Furthermore, the final diagnosis requires thyroid lobectomy. The present study examined whether a differential protein expressio...

The clinical significance and potential morbidity of papillary thyroid microcarcinomas (PTMC) is discussed. Particularly the differences between those PTMC identified postoperatively in histological examination (incidentals), and those diagnosed preoperatively (non-incidentals). We retrospectively analysed differences in clinical presentation and course after treatment in these two groups. The study population consisted of 199 patients with PTMC who underwent surgery from 2000...

Introduction: Patients with MEN1 have increased morbidity and mortality compared to those patients with sporadic NETs. No genotype-phenotype correlation is described and age-related clinical penetrance surpasses 50 and 90% by 20 and 40 years, respectively. The aim of the audit was to compare the screening programme for MEN1 patients with MEN1 clinical guidelines.Methods: Case notes of MEN1 patients attending a tertiary NET-multidisciplinary team (MDT) in...

Introduction: Adult growth hormone deficiency (AGHD) is associated with lower bone mass and likely with increased risk of fragility fractures. GH replacement leads to increase in bone mineral density (BMD) and trabecular bone score (TBS). The effect of adequate levels of vitamin D during GH replacement is important to provide effect on TBS.Aim: To assess long–term effectof recombinant GH replacement on BMD and TBS with regards to vitamin D levels d...

Introduction: Acromegaly is a rare diseaseresulting most commonly from pituitary adenoma. A chronic increase of growth hormone (GH) and insulin-like factor 1 (IGF-1) leads to many systemic complications including osteoporosis and fractures. Radiofrequency echographic multi-spectrometry (REMS) is a new non-ionizing technique to diagnose osteoporosis.Purpose: The objective of the study was to evaluate bone mineral density (BMD) by REMS in patient...

Introduction: ‘Forgotten goiter’ is defined as a mediastinal thyroid mass discovered after total thyroidectomy. It is a rare clinical finding, usually asymptomatic.Case report: 88-years old woman was admitted to the Endocrinology Department with a suspicion of the retrosternal goiter. In her medical history there was thyroidectomy performed 16 years before because of multinodular goiter and she had recurrent lower respiratory tract infections...
