Background: Gestational Diabetes Mellitus (GDM) is one of the most common illness of pregnancy. Despite its frequency, there’s no worldwide accepted screening criteria for GDM. In 2011, Carpenter and Coustan (CC) screening (50-g glucose challenge test (GCT) followed by 100-g glucose tolerance test (OGTT) if GCT screen was positive) was abandoned and began the implementation of the screening of the International Association of Diabetes and Pregnancy Study Group (IADPSG) 20...

Introduction: Acromegaly is usually caused by a pituitary adenoma; ectopic or eutopic secretion of GHRH is a rare condition, responsible for <1% of the cases. Ectopic secretion of GH itself is even rarer.Case report: A 34-year-old woman was referred to the Endocrine Clinic with a multinodular goiter. However, on physical examination there were some physical signs of acromegaly: coarsening of facial features, protusion of the lower jaw and thick, oily...

Background: Takotsubo cardiomyopathy (TC) is characterised by acute, transient left ventricular apical ballooning precipitated by emotional or physiologically stressful stimuli and has been previously associated with Graves’ disease based on few clinical reports. More recently, the association with exogenous thyrotoxicosis and radioiodine-induced thyroiditis has also been described. Iatrogenic hyperthyroidism on patients under levothyroxine replacement therapy for hypothy...

Introduction: The acute onset of pulmonary edema and severe congestive heart failure secondary to catecholamine overproduction from a pheochromocytoma is a rare entity, especially in the absence of other signs or symptoms suspicious of this tumour. Myocardial involvement can include angina pectoris, acute heart failure, dilated cardiomyopathy, myocardial infartion and arrhytmias. Here, we present the case of a young man with no significant medical history who presented with ac...

Mitochondrial diseases are rare conditions with a wide phenotypic range. The inability of dysfunctional mitochondria to produce sufficient ATP results in multi-organic defects dependent on high aerobic such as pancreas. The most common endocrine disease related to mitochondrial diseases is diabetes mellitus and it is thought to be secondary to insulin deficiency. A 26-year-old pregnant patient with 26 weeks gestational age was referred to an Endocrinology appointment ...

Introduction: Amiodarone is an antiarrhythmic iodine-rich drug, known to induce thyroid dysfunction both due to its high iodine content and through amiodarone-induced thyrotoxicosis (AIT), being this latter process classified into three different types. Type 1 is associated with increased thyroid hormone synthesis; type 2 is a destructive process with thyroid hormone release and type 3 is thought to be a mixture of the former two. Since treatment options are different, there h...

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...

Introduction: The American Diabetes Association guideline states that the long-term use of metformin may be associated with biochemical vitamin B12 (B12) deficiency and periodic measurement should be considered, although isolated serum B12 measurement has low sensitivity and specificity. Homocysteine (Hcy) and methylmalonic acid (MMA) are more sensitive biomarkers, the latter being more specific.Objectives: To estimate B12 deficiency in type 2 diabetics ...
