Objectives: The angiotensin-converting enzyme (ACE1) gene is one of the most studied genes in the pathogenesis of type II diabetes (T2DM) and cardiovascular disease. However, in the context of exerciSemodels in T2DM, they are not yet fully understood. We intended to characterize the genetic profile of individuals with T2DM from an inter-individual point of view using prognostic markers and cardiovascular risk. On the other hand, relate it with the profile obtained wit...

Background: Immune checkpoint inhibitors (ICI) are an innovative oncologic therapy used in several types of solid and hematological neoplasms. This treatment enables the antitumoral immune system response and results in significant improvement of clinical outcomes and survival rate. However, endocrine related adverse effects (ERAE) have been related, with thyroid and pituitary dysfunction being the most common endocrine diseases described. An association between the surge of e...

Background and objective: According to recent studies, endocrine societies have modified the treatment criteria of subclinical gestational hypothyroidism, increasing TSH upper-limit value commonly set at 2.5 μU/ml to a new threshold set at 4 μU/ml. This change in criteria has responded to numerous studies which seem to indicate that the obstetrical complications do not generally increase despite this variation of the threshold TSH value. A further discussion lays now...

Introduction: Patients with germline mutations in one of the succinate dehydrogenase (SDH) genes are at substantially increased risk of developing paragangliomas (PGL) and pheochromocytomas (PCC). Mutations in SDHB are the most commonly found gene mutations in PC/PGL and are associated with younger ages at presentation, higher rates of metastases and poorer prognosis. Although familial PGL syndromes were initially thought to predispose only for PCC and PGL, other tumor types s...

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...

Introduction: Gastroparesis is defined by a delayed gastric emptying without mechanical obstruction. It can be a debilitating complication of diabetes that is poorly understood and has limited therapeutic options.Case reports: 1st case - We report the case of a 34-year-old woman with type 1 diabetes mellitus (T1DM) with diabetic nephropathy and gastroparesis, and a reasonable glycaemic control...

Introduction: Congenital hyperinsulinism (CHI) is a heterogenous disease caused by insulin secretion regulatory defects, being ABCC8/KCNJ11 the most commonly affected genes. It can present as focal or diffuse pancreatic disease, which is mainly determined by the genotype. Diazoxide is the first-line medication in diffuse cases, however many do not respond satisfactory. Second-line options include somatostatin analogues and surgery, which is curative in case of focal CHI.<p...

Medullary thyroid carcinoma (MTC) is a rare tumor of C cell origin, that may be sporadic or familial. Diagnosis is often delayed and its course variable.Objectives: Evaluation of clinical characteristics and outcome of patients diagnosed with MTC.Methods: Retrospective analysis of clinical records of patients with MTC between 2005 and 2016. We considered undetectable serum calcitonin as criteria of cure.Resul...

Introduction: Thyroglobulin (Tg) measurement in needle washouts from fine-needle aspiration biopsies (FNA-Tg) increases the sensitivity of lymph node (LN) metastasis diagnosis in differentiated thyroid cancer (DTC). However, the cutoff value for FNA-Tg has not been clearly established and there are large differences between clinical studies, which hinders its interpretation. Our study aimed to investigate the optimal cutoff value of FNA-Tg and evaluate its utility in the diagn...

Introduction: Although recognized as a risk factor in most staging systems, including the UICC TNM classification, the significance of microscopic extrathyroid extension (ETE) in papillary thyroid carcinoma (PTC) remains controversial. Despite this fact, its diagnosis by a pathologist following surgery for tumours ≤ 4 cm without metastases means an upstaging to pT3 and stage III in patients over 45 years, implying a poorer survival. Our study aimed to evaluate the impact...
