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: In most cases, adrenal masses are non-functioning adrenocortical adenomas. On ‘Management of adrenal incidentalomas: European Society of Endocrinology Clinical Practice Guideline’ published in 2016, the experts ‘suggest against repeated hormonal work-up in patients with a normal hormonal work-up at initial evaluation unless new clinical signs of endocrine activity appear or there is worsening of comorbidities’.C...

Introduction: Factitious hypoglycemia results from surreptitious administration of insulin or insulin secretagogues. It can involve non-diabetic individuals with knowledge of hypoglycemiant drugs, or diabetics manipulating the doses.Clinical case: A 42-year-old women, type 1 diabetic since the age of 14, on intensive insulin therapy (A1C: 8.5%), was hospitalized for study of recurrent severe hypoglycemia in the last 2 months, despite successive insulin d...

Introduction: The association of fasting glucose (FG) in early pregnancy (EP) with adverse outcomes for the mother and her offspring is well known, although the best cut-offs for diagnosis of Gestational Diabetes (GD) are not consensual.Objetive: Evaluate the impact of FG in EP in the management of pregnant women and obstetric and fetal outcomes.Methods: Retrospective cohort of pregnant women with GD diagnosed before 24 weeks of ge...

Introduction: Due to the growing prevalence of obesity, more women are overweight in early pregnancy, leading to adverse neonatal and obstetric outcomes.Objective: To evaluate the influence of maternal prepregnancy body mass index (BMI) on blood glucose levels at diagnosis of gestational diabetes (GD), obstetric and neonatal outcomes.Methods: Retrospective observational study including women with GD and singleton pregnancy, with fo...

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 ...

Introduction: Insulin autoimmune syndrome or Hirata disease is a rare cause of hypoglycemia without prior insulin exposure. Approximately 400 cases were reported, mostly in Japan. It’s associated with other autoimmune diseases or exposure to sulfhydryl-containing drugs.Case report: A 56-year-old Caucasian woman presented with a 20-month history of hypoglycemia ameliorated by sugar intake. She had a past history of autoimmune thyroiditis, asthma and ...

Introduction: Diabetes mellitus (DM) is one of the main causes of end-stage renal disease (ESRD). Renal transplantation is the most effective form or renal replacement.Methods: Retrospective, descriptive study of a sample of 108 diabetic patients admitted as candidates to renal transplant from January 1991 to December 2011, using the SPSS programme, version 20.0.Results: 11 women and 97 men were evaluated (medium age: 58±8.2 y...

Introduction: The 2019 European Society of Cardiology/European Atherosclerosis Society lipid guidelines changed the cardiovascular risk categories and LDL-C goals, and suggests that lipoprotein(a) [Lp(a)] measurement should be considered at least once in adult person’s lifetime. Although young people with type 1 diabetes (T1DM) without major cardiovascular risk factors (CVRF) were previously considered to be at low or moderate risk, they are at least at moderate risk bas...

Introduction: Diabetic nephropathy is the main global cause of end stage renal disease. According to the annual report from the Portuguese National Diabetes Observatory, in 2013, the prevalence of diabetes mellitus (DM) in new cases of chronic kidney disease was 31.2 and 11.1% in kidney transplant patients.Aim: To characterise the population of type 2 diabetic patients admitted in diabetes and kidney transplant consult (DKTC), comparing those admitted be...
