Introduction: Polycystic ovary syndrome (PCOS) is a frequent cause of infertility. Its influence on the results of in vitro fertilization (IVF) is controversial, and generally not isolated from the effect of obesity. A relationship between the FSH receptor (FSHR) polymorphism Asn680Ser and the risk and phenotype of PCOS has been studied with conflicting results.Objectives: To analyze the influence of obesity and PCOS on the gonadal axis...

Introduction: Gestational Diabetes Mellitus (GDM) is one of the pregnancy diseases with the highest rate of complications, influenced by several factors. Its prevalence has increased, with a prevalence of 7.2% in Portugal.Objective: Characterize pregnant women with GDM and evaluate the perinatal outcomes according to the country of origin and previous GDM.Material and methods: Cross-sectional and retrospective study. We collected c...

Introduction: Estimated prevalence of hypertension (HT) in Portugal is 42%. It is a major risk factor for coronary heart disease and cerebrovascular disease, the leading mortality cause in Portugal. Primary aldosteronism (PA) was once recognized as rare cause of secondary hypertension and hypokalemia a condition present in all cases. Nowadays, prevalence of this condition is about 10% in HT patients, being the commonest form of secondary HT. Secondary forms of HT should be exc...

Background: Takotsubo cardiomyopathy is a rare, acute, nonischemic cardiomyopathy causing transient systolic disfunction of the apical and/or mid segments of left ventricle and is commonly associated with emotional and physical stress. Thyrotoxicosis is a rare cause of this condition, resulting from direct and indirect action of thyroid hormones on the cardiovascular system.Case presentation: A 43-year-old woman presented at emergency room with chest pai...

Thyroid nodules are a common clinical finding, with an estimated prevalence of palpable thyroid nodules to be approximately 5% in women and 1% in men. The clinical importance of thyroid nodules rests with the need to exclude thyroid cancer. The prevalence of malignancy reported for palpable thyroid lesions ranges from 5.0% to 6.5%. Patients with benign thyroid nodules are unlikely to suffer morbidity or mortality due to thyroid cancer. A 53 aged man presented with a 20-year hi...

Background: Amiodarone is an antiarrhytmic drug used mainly in atrial fibrillation. Amiodarone-induced thyrotoxicosis (AIT) is less common than hypothyroidism, but it represents a true therapeutic challenge. AIT can be due iodine load (type 1) or a destructive thyroiditis (type 2).Methods: Retrospective study of patients with AIT, diagnosed between 2010 and 2015, in a central hospital. We reviewed medical records regarding age, gender, amiodarone therapy...

Background: Type 2 diabetes and Hipertension are common in obese patients. Bariatric surgery is effective in sustained weight loss, but also improves glycemic and hypertension control. A high percentage of diabetes remission occurs.Methods: Retrospective study of type 2 diabetic patients submitted to bariatric surgery between 2006 and 2013 in a central hospital. Primary endpoint was evaluation of diabetes and hypertension remission, 2 years after surgery...

Background: Obesity is related to an increased cardiovascular risk, namely coronary heart disease risk (CHDr). Type 2 diabetes (T2D) is frequently associated with obesity and, by itself, is an important CHDr factor. Interventions that induce weight loss would be expected to attenuate CHDr in obese patients.Aims: To evaluate variation in cardiovascular risk profile one year after adjustable gastric banding (AGB), in obese patients (with and without T2D); ...

Introduction: Primary Hyperparathyroidism (pHPT) is a calcium metabolism disease, resulting from one or more parathyroid glands hyperfunction. Ultrasonography and Technetium Sestamibi are, nowadays, the first line imaging techniques for diagnosis. Recently, a 4-dimensional computed tomography (4D-TC) protocol has emerged, presented in the last endocrine surgery guidelines. It is a dynamic imaging exam based on the parathyroid contrast uptake pattern, whose sensitivity and spec...

Introduction: The use of Continuous Subcutaneous Insulin Infusion (CSII) is expected to improve glycemic control and to reduce hypoglycemia events. However, long-term beneficial results in glucose control are not always observed. We evaluated long-time glucose control and severe hypoglycemias in type 1 diabetic patients using CSII, without continuous glucose monitoring.Patients and methods: This was a retrospective study of adult type 1 diabetic patients...
