Introduction: Methimazole is the thionamide compound most used in the treatment of hyperthyroidism due to its efficacy, commodity and security. Severe side effects are rare, although potentially fatal: agranulocytosis in 0.1–0.5% and toxic hepatitis in 0.1%Aims: To characterize the patients admitted in the endocrinology ward for the last 10 years for severe complications of methimazole therapy.Material and Methods: Retrospecti...

Background: Most thyroid specific genes are transcriptionally regulated by TSH-TSHR signalling and T4-driven negative feedback of TSH secretion at the pituitary. However, local autoregulation of transcription has been described from IGF-IGFR, follicular thyroglobulin, or iodine. We aimed to investigate the TSH dependency of thyroid transcriptional regulation in the Dehal1 knockout, devoid of iodide-recycling capacity from iodotyrosines.Methods: ...

Introduction: Bilateral adrenal hemorrhage (BAH) is a rare clinical condition (estimated incidence between 0.14% –1.8%, according to postmortem studies) and life-threatening due to the development of adrenal crisis, after the destruction of 90% of each adrenal gland. A mortality rate of 15% has been reported despite treatment, but it depends on the severity of the underlying condition, reaching 90% in cases of sepsis, or even higher if it is not diagnosed quickly enough....

Introduction: Hypoparathyroidism (hypoPT) is the most frequent complication after thyroid surgery, usually as transient hypocalcaemia. Permanent parathyroid lesion is less frequent, but it can extend hospital stay and complicate postoperative management. Several preoperative factors predicting the development of hypoPT have been identified, including advanced age, hyperthyroidism, surgical experience and others. We evaluate the role of some potentially predictive factors in ou...

Introduction and objective: CD36 is a scavenger receptor that facilitates the membrane transport of long chain fatty acids into muscle and adipose tissue. Polymorphisms in this gene have been related to abnormal serum fatty acids and obesity-related phenotypes with inconsistent results. Gene-diet interactions could modulate these associations. Our aim was to study whether a common functional variant (rs1761667) in this gene will associate with anthropometric variables and plas...

Introduction: Pituitary tumors can be classified according to their endocrine function, starting from the clinical phenotype to establish a diagnosis. The histological analysis can confirm the clinical suspicion. A thorough classification is essential in the therapeutic approach with an important influence in the disease-free survival.Case report: We report a case of a 16-year-old male, with loss of visual acuity and headache, attended by an Ophthalmolog...

Introduction: Cushing’s disease (CD) is a Grave disease that requires a multidisciplinary and individualized treatment approach.Case report: We describe the case of a 31-years old female patient with Cushing disease diagnosed in 2007. She initially complained of weight fluctuations, amenorrheia, rounded face with plethora and acne, for 1 year duration. Analytically: 0800 h plasma cortisol of 14 μg/dl (5–25) and 2300 h 15 μg/dl, ACTH 1...

Objective: Relationship between pre-pregnancy BMI (PPBMI) in gestational diabetic (GD) patients, and age, country of origin, family history of type 2 diabetes mellitus (T2DM), GD history, and BMI after pregnancy.Methods: Transversal, descriptive study of 259 consecutive pregnant with confirmed DG. Analysis were based on Fisher’s exact test and Student’s t-test. A P<0.05 was significant (SPSS 19.0).Re...

Introduction: Type one diabetes is estimated to account for 1% of the pregnancies complicated by diabetes, associated with an increased risk of maternal and perinatal morbidity. The multidisciplinary follow up of the diabetic women can contribute to an improvement of the glycemic control, minimizing the obstetric and perinatal complications.Aims: To characterize pregnant women with type one diabetes followed in our Department’s Endocrinology/Obstetr...

Introduction: Sleep disordered breathing (SDB) promotes structural myocardial changes and can trigger cardiac arrhythmias. Acromegalic patients have high prevalence of SDB and GH–IGF1 excess is related to a specific cardiomyopathy characterized by concentric cardiac hypertrophy and diastolic dysfunction. The aim of this study was to assess the relationship between SDB and cardiac dysfunction on acromegalic patients.Material and methods: Observationa...
