The role of the sympathetic nervous system (SNS) in the pathophysiology of PCOS and associated cardiometabolic risks is emerging. Previous studies support increased SNS activity in PCOS, potentially contributing to metabolic features via multiple mechanisms including insulin resistance. Moxonidine is a second-generation imidazoline I1 agonist, acting centrally, inhibiting sympathetic outflow at the level of rostral ventrolateral medulla with known beneficial effects...

Objective: To retrospectively evaluate the results of the pheochromocytoma surgery in our institution assessing the surgical complications, perioperative hemodynamic instability and oncologic outcomes.Methods: The medical records of patients admitted for pathologically confirmed pheochromocytoma between 2000 and 2015 were reviewed. Patients with paragangliomas were excluded.Results: We identified 40 patients with 43 resected pheoch...

Introduction: A useful tool for disease clinical characterization and treatment of type 2 diabetes is the knowledge on the status of several biomarkers. The aim of this study was to evaluate the levels of cardiovascular, oxidative stress and nutritional biomarkers and their relationship with the presence of type 2 diabetes and angiopathy.Methods: A population-based case-control study in 150 Portuguese type 2 diabetic patients was performed. Group I &#150...

Introduction: Turner syndrome is one of the most common human chromosomopathy and represents an important cause of short stature and ovarian insufficiency. It is caused by total or partial loss of X-chromosome and its prevalence is about 1 in 2000–2500 live female births.Objectives: To review the patients with TS followed in a Paediatric Endocrinology Unit since 1999.Methods: A retrospective study regarding diagnosis, course, ...

Idiopathic congenital hypogonadotropic hypogonadism (CHH) is a rare reproductive disorder that is primarily caused by a gonadotrophin-realising hormone (GnRH) deficiency. When CHH is associated with hyposmia or anosmia is designated by Kallmann Syndrome (KS). This syndrome is a genetic disorder with significant genetic heterogeneity that may present as a sporadic or familial case, following autosomal dominant, autosomal recessive, or X – linked recessive modes of inherita...

Introduction: Hypopituitarism is a clinical syndrome of deficiency in growth hormone (GHD) production, which can occur isolated or associated with others pituitary defects. GHD has an incidence of 1:4000 to 1:10 000. It may be idiopathic, congenital or acquired.Purpose: Characterize the paediatric population with GHD followed at the Paediatric Endocrinology Unit of our centre and compare the clinical presentation and treatment response of the patients wi...

Aims: To assess the incidence of Ipilimumab associated hypophysitis and its common presentations.Methods: All patients who developed Ipilimumab induced hypophysitis following treatment for Malignant melanoma at a large tertiary care centre in West Midlands, United Kingdom from 2012 to 2014 were included in the study. Patients with known pituitary disease prior to treatment and/or received other systemic immunotherapy following Ipilimumab treatment were e...

Background: Calcitonin is a hormone secreted by thyroid C cells, and is considered an excellent marker for medullary thyroid carcinoma (MTC). However, the use of calcitonin to screen patients with nodular thyroid disease (NTD) remains controversial.Objective: Defining the frequency of hypercalcitoninemia among NTD patients followed at a tertiary referral hospital.Methods: Retrospective analysis of basal calcitonin measurements and ...

Background: NET-related symptoms such as flushing and diarrhoeas as well as disease related worries reduce quality of life in patients with neuroendocrine tumours (NETs). Peptide receptor radionuclide therapy (PRRT) is an established treatment in NETs and has been shown to prolong survival. However quality of life data post PRRT is lacking.Aim: To evaluate the symptoms prevalence, intensity and their relation to quality of life in patients receiving PRRT...

Introduction: Adiponectin, adipocyte fatty acid-binding protein (A-FABP), fibroblast growth factor 21 (FGF-21), C1q/TNF-related protein 9 (CTRP9) and allograft inflammatory factor-1 (AIF-1) belong to the proteins produced by adipocyte tissue, which differently contribute to oxidative stress, chronic inflammation, insulin resistance and endothelial damage. The aim of this pilot study was to compare their levels in patients with diabetes and in healthy individuals and determine ...
