Background: Multiple endocrine neoplasia type 1 (MEN1) (OMIM 131100) is an autosomal dominant disorder associated with a high risk of developing parathyroid hyperplasia (90%), digestive neuroendocrine tumors (30–70%) and pituitary adenomas (30-40%). Prevalence of MEN1 is 2-10/100.000, there are no differences between men and women and usually, it is diagnosed before 40 years old. It is related to different mutations of the MEN1 tumour-suppressor gene (OMIM: 613733) which ...

Background: Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is associated with an increased cardiometabolic risk in adult life. Nevertheless, data regarding pediatric age is scarce. We aimed to evaluate cardiometabolic risk factors in patients with CAH due to 21-hydroxylase deficiency in pediatric age.Methods: We reviewed the clinical records of patients with CAH evaluated in a Pediatric Endocrinology Unit in a central hospital. Pat...

Introduction: Recent studies suggest that the use of dipeptidyl peptidase 4 inhibitors (DPP-4i) may be associated with an increased risk of developing bullous pemphigoid; which has led to publication of several pharmacovigilance alerts.Objectives: To characterize the potential association between the use of DPP-4i and the risk of developing bullous pemphigoid.Material & methods: Observational, retrospective study based on clini...

Introduction: DIPNECH is a preinvasive condition in which there is an idiopathic generalised proliferation of pulmonary neuroendocrine cells that can form tumourlets. There are very few cases described of ACTH secretion by these cells causing Cushing’s syndrome, some of them cyclic.Case report: A 41 year-old woman was sent to our Endocrinology outpatient clinic for menstrual disturbance, acne and excessive sweating. She had a recent diagnosis of DIP...

Introduction: Simple aspiration is the first-line treatment used for benign cystic thyroid nodules. However, a high recurrence rate has been reported with this procedure. When this happens, percutaneous ethanol injection into the nodules has proven to be an effective technique which can reach a volume reduction of about 85% (Kim et al., Eur Radiol. 2012 Jul;22(7):1573–8).Material and methods: Descriptive analysis of percutaneous 96° et...

Introduction: Recent studies seem to support a bidirectional positive interaction between aldosterone and parathyroid hormone (PTH). Understanding the normal physiological relationship between renin-angiotensin-aldosterone system (RAAS) and PTH is of clinical interest because their inappropriate activity may negatively impact cardiovascular and skeletal health.Objective: To evaluate the presence of an interaction between aldosterone and PTH in a cohort o...

Introduction: Diabetic ketoacidosis (DKA) is an endocrine emergency and the leading cause of morbi-mortality in children with type 1 diabetes mellitus (1DM). DKA treatment is still controverse, mainly regarding hydroelectrolytic replacement and insulin dose.Aims: To evaluate efectiveness and safety of our tertiary centre protocol in DKA treatment, which included initial volume expansion with isotonic saline in the first two hours followed by 0.45% sodium...

Adverse events during gestation in rodents, results in an enhancement of immune function, including elevated levels of inflammatory cytokines in the brain. Liraglutide is a GLP-1 receptor agonists known to exert neuroprotective effects in brain. The aim of this study was to elucidate if liraglutide given to food restricted (FR) pregnant rats may prevent the deleterious effects of FR in the hippocampal inflammatory status of male and female pups at 21 days of age (D21). 20 Spra...

Secondary endocrine hypertension affects around 10% of all hypertensive population, most frequently primary aldosteronism (PA). Less frequent forms of adrenal hypertension include pheochromocytomas and other causes of mineralocorticoid excess than PA, featuring suppressed renin without excess of aldosterone. Featuring. We present a 29-year-old woman with difficult to control hypertension diagnosed two years before and poor response to ACEI and ARA II treatment. She was referre...

Background and Aim: Unacylated ghrelin (UAG) is the major form of circulating ghrelin. Initially considered as a non-functional peptide, soon after UAG has been associated to a negative action on energy balance, suppression of hepatic glucose production and decrease in circulating levels of insulin. The aim of this study was to analyze the association between the serum levels of UAG and glucose metabolism parameters in obese women, independently from the eventual interference ...
