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...

Introduction: The autoimmune process is currently the most common cause ofthe primary adrenal insufficiency cases in developed countries. The complexity of this process consists of genetic, immunological and environmental factors. It has been proven that vitamin D (VD) inhibits the production of inflammatory cytokines and can modulate immune-regulatory mechanisms.Purpose: The aim of our study was to evaluate the prevalence of VD insufficiencyin...

Thyroid hormone has long been known as a key developmental factor in human and model species. Insufficient thyroid hormone during development can impair the growth and maturation of diverse tissue and organ systems. One of the most serious risks associated with congenital hypothyroidism is defective brain maturation and mental retardation. However, in recent years, targeted mutagenesis of the thyroid hormone receptor genes in model species has expanded our understanding of the...

Cushing’s disease is a debilitating endocrinopathy characterized by excessive cortisol levels in the blood which may be produced from tumours of the pituitary gland. The only way to achieve long term cure of Cushing’s disease is by Transphenoidal removal of the adenoma. ketoconazole, inhibit steroid (cortisol) production in the adrenal glands.The use of glucocorticids treatment before and after hypophisectomy is a classic management in the peri...

Kisspeptin-54 is a neuropeptide encoded by the Kiss-1 gene with an important role in the regulation of reproduction and puberty. Acute peripheral or intra-hypothalamic administration of kisspeptin-54 potently stimulates the hypothalamo-pituitary-gonadal (HPG) axis via hypothalamic gonadotrophin releasing hormone (GnRH) neurons. However, the effects of chronic continuous kisspeptin administration are poorly characterised. Our studies investigated the effects of chronic, continu...
