Hypocalcemia has been recently identified as a major biochemical distinctive feature of COVID-19, predicting poor clinical outcomes. Besides the calcium-dependent viral mechanisms of action and the enhanced cellular permeability to calcium ions, we previously hypothesized that hypovitaminosis-D could be a predisposing factor to hypocalcemia. Actually, high prevalence of vitamin D (VD) deficiency in COVID-19 patients (pts) was reported by several studies, but, to date, only few...

Background: Ultrasound guided minimally invasive therapies are becoming increasingly popular for the treatment of symptomatic benign thyroid nodules. Efforts have been directed on the prediction of volume reduction as a measure of efficacy of the procedure. Aim of the present study is to identify predictors of 6-months volume reduction rate (VRR) after radiofrequency ablation of benign thyroid nodules.Materials and Methods: We performed a retrospective s...

Introduction: Nonfunctioning pituitary adenomas (NFPAs) are a heterogeneous group of tumors with different presentations. Clinical management of these tumors is complex. Our aim was to evaluate the clinical characteristics/postsurgical outcomes of NFPAs and to identify predictive factors of good response to surgery.Methods: Retrospective analysis of NFPA, who underwent surgery and followed in our hospital, from 2015-2022.Results: W...

Introduction: Although inpatients hyperglycemia is a current uneasiness among the medical community, its prevalence in Portugal in unknown. We aim to identify ‘Stress hyperglycemia’ and ‘New onset diabetes’ cases in inpatients in a district hospital.Methods: We evaluated inpatients from Internal Medicine (IM), General Surgery (GS), Orthopedics and Traumatology (OT) and Stoke Unit (SU) departments, admitted from the emergency departmen...

Objective: The aim of this study was to evaluate the treatment outcomes in patients with autonomous toxic nodule (ATN) that received a radioiodine treatment (RAIT) and to determine the influence of age, gender, nodule size and iodine activity.Methods: We performed a retrospective study of all RAIT done for hyperthyroidism (n=149) in our hospital during 2014 and 2015. Patients with ATN submitted to RAIT were selected to analysis. We studied 58 pa...

Primary Aldosteronism (PA) is the most prevalent cause of secondary hypertension. The aim of this work was to characterize the diagnostic workup, treatment and follow-up of confirmed PA.The adrenal tumour study group of the Portuguese Society of Endocrinology undertook the first retrospective multicentre study of Portuguese PA patients. Data was gathered from nine Portuguese Endocrinology centres (three in the north, one in the centre and five in the sou...

Background: Septo-optic dysplasia (SOD), also known as de-Morsier syndrome, is a rare congenital disorder characterized by any combination of optic nerve hypoplasia, pituitary dysfunction and midline abnormalities of the brain. Clinical diagnosis requires the presence of at least two of the features. This disorder is equally prevalent in males and females, with a reported incidence of 1/10,000 live births. There is wide variation in the severity of the clinical features found....

Introduction: Multiple endocrine neoplasia (MEN) is a rare genetic syndrome characterized by occurrence of tumors involving two or more endocrine glands. Four types are described: MEN1, MEN2, MEN3 and the recently identi&#-1279;ed MEN4. Due to the complexity of the syndromes, it is difficult to manage these patients. Our objective was to describe the clinical features of individuals from 7 families with a diagnosis of MEN1 or MEN2 and identify current challenges in clinical pr...

Objective: The purpose of this study was to assess clinical outcomes of patients with toxic adenoma (TA) treated with Radioactive Iodine (RAIT) in a tertiary hospital over a period of 8 years. We also analysed the influence of age, gender, TSH at diagnosis and anti-thyroid drugs (ATD) previous to RAIT on the cure rate.Methods: Retrospective analysis of clinical records of all patients with TA submitted to RAIT between 2008 and 2015. The influence of demo...

IntroductionPrimary hyperparathyroidism (PHPT) is a common endocrine disorder and classically associated with hypercalcemia (HHPT). There is a newest variant of PHPT, defined by normal albumin-corrected calcium levels - normocalcemic PHPT (NHPT) – which may represent an early stage of HHPT. Nevertheless, there is limited data on how this variant presents clinically and biochemically.AimTo evaluate the de...
