Background: Bilateral adrenal haemorrhage (Waterhouse–Friderichsen syndrome) is a rare consequence of sepsis (usually a result of meningococcal infection), with an estimated 15% mortality. Despite the predominant association with meningococcal infection, there are other recognised aetiologies: sepsis resulting from other organisms, and non-infectious causes, such as anticoagulant treatment, trauma and postoperative adrenal haemorrhage.Case report: A...

Introduction: Adrenocortical carcinoma (ACC) is a rare neoplasm with a variable but overall poor prognosis. The presentation is heterogeneous usually with mass effect and less often with evidence of hormonal secretion. About half of cases the tumors are hormonally active most commonly with cortisol secretion followed by sexual hormones production, being rare the aldosterone secretion.Case report: A 41-year-old male presented with hypertensive crisis and ...

Introduction: The Neuroendocrine Tumors Study Group of the Portuguese Endocrine Society (SPEDM) performed the first observational study between November 2012 and July 2014 too assess the profile of Gastroenteropancreatic Neuroendocrine Tumours (GEP-NET) patients (pts) followed at the main Portuguese hospitals. Several demographic and clinical data were collectedObjective: Characterize the clinicopathological features and treatment of patients with NET or...

Introduction: Chromogranin A continues to be one of the most valuable markers for neuroendocrine tumors (NETs) however, it has several limitations, including its reduced specificity.Methods: The authors present the case of a patient diagnosed with a midgut NET, during follow-up.Results: Male patient, 61 years old, with chronic renal disease (CRD), underwent right hemicolectomy owing to ileo-cecal valve lesion; hist...

Introduction: Von Hippel–Lindau syndrome (VHL) is an autosomal dominantly inherited neoplastic disorder with marked phenotypic variability, characterized by a broad spectrum of clinical manifestations in central nervous system (CNS) and viscera. Specific gene mutation can be demonstrated; however imaging plays an important role in diagnosis. 68Ga-labelled somatostatin analog (68Ga-DOTANOC) PET-CT is routinely employed for somatostatin receptor (SSTR) imaging, mainly for n...

Trabecular bone score (TBS) is a recent noninvasive analytical method, based upon DXA images, related to bone microarchitecture or bone quality; together, TBS and DXA may evidence bone strength. Falls and osteoporotic fractures increase with ageing, while both BMD and vitamin D levels slowly decline. Data about the influence of vitamin D on the TBS are scarce.Aim: To evaluate the influence of the blood vitamin D levels on the TBS in normal men.<p cla...

Introduction: Fahr syndrome (FS) is a neuropsiquiatric condition due to progressive basal ganglia calcification. Although physiopathology is not completely understood, it may be secondary to infectious, metabolic and genetic diseases.Case report: A 65-year-old male Caucasian was referred to the outpatient endocrine department because of hypocalcaemia. No perioral paresthesia or tingling of the fingers and toes were noticed. He complained of longstanding ...

Introduction: Pseudohypoparathyroidism (PHP) refers to a heterogeneous group of disorders that have in common end-organ unresponsiveness to parathyroid hormone (PTH). The most frequent form, PHP type 1, results from different genetic/epigenetic changes in the GNAS gene.Case 1: Woman, 25 years-old, sent to Endocrinology from Genetics consultation after her daughter had been diagnosed with PHP type 1a (heterozygous pathogenic variant at exon 13 of...

Introduction: Analysis of epidemiologic patterns in diabetes helps with understanding of etiology, natural history and current and future needs. Bangladesh is a low-middle-income, densely populated country where there is limited information regarding incidence of childhood diabetes.Aim: To assess the type of diabetes in children and young adults in Dhaka, Bangladesh, from July 2011 until June 2016, and estimate minimum incidence of type 1 diabetes (T1D)....

Aim: To analyze the effects of inositol administration on parameters related to glucose homeostasis.Material and methods: Systematic review and meta-analysis of articles published in Medline or Web of Science Until February 1, 2016. We included studies that met the following criteria: i) Randomized controlled clinical trials of inositol/inositol isomer supplementation against placebo in parallel design, ii) performed in humans, iii) with information abou...
