Introduction: Thyroid hormones modulate the insulin sensitivity and glucose metabolism. The interrelation between thyroid autoimmunity, thyroid function, glucose metabolism and cardiovascular risk factors remains uncertain.Methods: We recorded thyroid function tests, BMI, IR markers comprising the Homeostasis Model Assessment for insulin resistance (HOMA-IR and HOMA-B), the Quantitative Insulin Sensitivity Check Index (QUICKI), HISI (Hepatic Insulin Sens...

Introduction and Aim: Dopamine receptor D2 (DRD2) polymorphism (rs1800497) appears to be associated with increased susceptibility to the development of type 2 diabetes mellitus (T2DM). The dopamine transporter (DAT) determines dopamine signalling, responsible for the reuptake of its active form from the synapse. Polymorphism in the DAT gene (rs2836317) can increase dopamine reuptake in the synaptic cleft. However, its association with T2DM is still controversial.<p class="...

Introduction: Hypercalcemia is not uncommon in clinical practice and may present as a life-threatening emergency. Its main aetiologies are primary hyperparathyroidism (80% parathyroid adenomas; 20% multiglandular hyperplasia, <1% parathyroid carcinomas) and hypercalcemia of malignancy, with or without presence of bone metastases.Case Report: We present a case of a 77 years-old male, submitted to a subtotal gastrectomy at the age of 73 due to a perfor...

Introduction: In chronic diseases a good psychological and behavioral adaptation is essential. Concerning diabetes the Insulin Delivery System (IDS) adopted tend to be an important factor of adaptation, global satisfaction and, above all, quality of life (QoL).Objectives: To analyze the QoL and IDS satisfaction and its relationship with psychopathological symptomatology in patients on continuous subcutaneous insulin infusion (CSII) therapy.<p class="...

Introdution: Prolactinomas in men are rare and the majority are macroadenomas. Some studies suggest that these tumors in men have higher proliferative activity and aggressiveness indicating gender-specific differences in biological behavior. Dopamine agonists (DA) are considered first-line therapy.Material/methods: Retrospective analysis of male patients diagnosed with prolactinoma between 2005 and 2016. Age at presentation, clinical, hormonal and image ...

Introduction: The incidence of glucose metabolism alterations during the follow-up of surgically treated insulinomas is largely unknown. Our aim was to evaluate the incidence, and the clinical characteristics, of diabetes and prediabetes in this population.Methods: We retrospectively analyzed the cases diagnosed as insulinomas in a Central Hospital in Portugal in the period between January 1980 and December 2015.Results: We identif...

Introduction: Insulinomas are pancreatic endocrine tumors originating in the beta cells, characterized by hypoglycemia resulting from insulin hypersecretion.Objectives: To characterize the demography, the clinical features, imagiological findings and pathological evaluation of the cases of insulinomas identified in the previous 35 years at São João Hospital.Methods: We retrospectively analyzed the cases diagnosed as insul...

Introduction: Familial hypocalciuric hypercalcaemia (FHH) is a rare genetically heterogeneous disorder, with 3 variants described. An inactivating mutation in the calcium sensor receptor (CASR) gene causes the subtype 1, which represents 65% of the cases.It is charaterised by hypercalcaemia and hypocalciuria with normal or elevated PTH. FHH is generally assymptomatic and treatment is not needed. Differential diagnosis with primary hyperparathyroidism (PH...

Introduction: Hypoglycemia is a major limiting factor in intensive glucose control in diabetes mellitus. Its incidence has been increasing with the demand for intensive therapy for the prevention of the diabetic chronic complications. There are few studies in our country regarding the evaluation of hypoglycemia in the emergency room (ER).Objective: To characterize severe hypoglycemia episodes and patient features in individuals admitted to the ER.<p ...

Introduction: Severe hypoglycemia is defined as an episode that requires the assistance of another person in order to correct it. Most of the costs associated with hypoglycemia in diabetes mellitus patients are the result of severe episodes, when treated by health care professionals. In our country there are few studies regarding the epidemiology of episodes of hypoglycemia evaluated in the pre-hospital care setting.Methods: We retrieved all episodes of ...
