Introduction: Amiodarone is an effective drug in the management of supraventricular arrhythmias. Due to its composition rich in iodine and pharmacological properties can cause thyroid dysfunction in 15–20% of the treated patients. Clinically it can present in the form of amiodarone-induced hypothyroidism or amiodarone-induced thyrotoxicosis. This latter situation may result from an excess of iodine supply, glandular destruction or both pathogenic mechanisms.<p class="...

Introduction: The aging population brought new challenges in several diseases. Pituitary tumors are usually not related with elderly, although the rise in life expectancy has allowed its diagnosis in unusual age groups.Aim: To describe the pituitary tumors diagnosed in patients with age ≥ 80 yearsMethods: Retrospective observational study which included 23 patients with pituitary tumors with age ≥ 80 years observed in c...

Introduction: Turner syndrome (TS) is one of the most common chromosomal abnormalities, characterized by systemic involvement and susceptibility to some disorders that begin or progress in adult life. These lead to an increase in morbidity and mortality and a decrease in quality of life. The aim of this study was to analyse the profile of women with TS, who are currently followed in endocrinology, regarding: karyotype, age, final height and weight, puberty and fertility, and m...

Background: Low serum testosterone (LST) is associated with some chronic diseases, changes in body composition and resistance to insulin. Diabetes is one condition that has high prevalence of LST.Objetive: To determine the prevalence of LST in men with diabetes and its relationship with age, anthropometric and biochemical data.Material and methods: A cross-sectional study of 65 men with type 1 and type 2 diabetes was conducted, wit...

Background: In the recent years, Vitamin D role has grown in cardiovascular and inflammatory diseases, and some relations were made with low serum testosterone (LST) levels. It is equally known that in patients with diabetes, the prevalence of LST is higher.Objetive: To determine the prevalence of low levels of vitamin D and its relation with LST in men with diabetes.Material and methods: A cross-sectional study of 65 men with type...

Background: Amiodarone is a potent antiarrhythmic drug used to treat tachyarrhythmias. However, is linked to a number of adverse effects, including thyroid dysfunction. It is the main cause of drug-induced thyrotoxicosis. Here we report a clinical case of amiodarone-induced thyrotoxicosis (AIT) in a patient with complex ventricular dysrhythmia.Case report: A 23 years-old women with dilated cardiomyopathy, severe depression of ejection fraction of left ve...

Introduction: Turner Syndrome (TS) is associated with cardiovascular anomalies and account for a threefold higher mortality in these women. The most common findings are congenital malformations of the heart (CMH), aortic dissection, valvular heart disease (VHD), hypertension and ischemic heart disease. It has been suggested that the ocurrence of cardiovascular disease in TS women is related to their karyotype and possibly to growth hormone (GH) treatment. Our study aimed to as...

Introduction: Adult-onset autoimmune diabetes (AID) has two different phenotypes: classic type 1 diabetes mellitus (T1DM), with insulin requirement just after diagnosis, and latent autoimmune diabetes in adults (LADA). According to the Immunology of Diabetes Society, LADA diagnostic criteria are: age of onset of 30 years or more, any islet autoantibody, absence of insulin requirement for at least 6 months. The purpose of this study is to characterize patients with AID followed...

Introduction: Primary aldosteronism (PA) is the principal cause of arterial hypertension potentially treatable. The diagnosis is dependent of tests to identify patients who will benefit most with surgical treatment. ACTH stimulation test (AST) has been described as a useful confirmatory test, potentially identifying bilateral disease in patients without adrenal tumors.Aim: Evaluate the AST in patients with hypertension and positive screening test for PA,...

Introduction: Pheochromocytomas are catecholamine-producing tumors originated from the chromaffin cells of the adrenal medulla. Although usually sporadic, this tumors could be associated with germline mutations in about 40% of cases. TMEM127 has recently been identified as a novel gene conferring increased susceptibility to pheochromocytoma.Case report: A 42-year-old woman was referred to our Hospital to perform a right adrenalectomy for pheochromocytoma...
