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...

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...

Type 1 diabetes mellitus (T1D) is an autoimmune disease that results from the destruction of insulin producing β cells, in genetic susceptible individuals. Vitamin D (Vit D) is mostly known for its role in bone and calcium metabolism, however it is also involved in the modulation of the immune response. Serum levels of vitamin D partly depend on diet and sunlight exposure. However, genetic factors are also involved. Patients with T1D have been reported to have a higher pr...

Cushing’s syndrome is a rare disorder in children and adolescents. The diagnosis can be a challenge for the clinician, as its principal feature – obesity – is extremely common. We present three cases diagnosed in the last 20 years. The first one was a boy aged 17 that presented in 1984 with central obesity, acne, moon face with plethora, abdominal striae, easy bruising and skin atrophy. The investigations performed consisted in cortisol and ACTH plasma measureme...

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: Klinefelter syndrome (KS) is characterized by the presence of supernumerary X-chromosome and thus a 47,XXY karyotype. This syndrome remains underdiagnosed, with only about 25% of patients being identified, and only 10% during childhood.Methods: Retrospective analysis of 11 KS patients followed-up in the Endocrinology Department of Coimbra’s Hospital and Universitary Center. The registered data included education and occupation, time an...

Introduction: Langerhan Cells Histiocytosis (LCH) is a rare heterogeneous idiopathic clinical entity involving clonal proliferation of Langerhan cells that may infiltrate most commonly bone, skin, lymph nodes or lungs. It affects mainly children between 5 and 15 years. The most common endocrine manifestation is diabetes insipida.Clinical case: The authors describe a case of a 19-year-old female patient, admitted in the Transition Follow-up of the Endocri...
