Objective: The purpose of this study was to assess clinical outcomes of patients with toxic adenoma (TA) treated with Radioactive Iodine (RAIT) in a tertiary hospital over a period of 8 years. We also analysed the influence of age, gender, TSH at diagnosis and anti-thyroid drugs (ATD) previous to RAIT on the cure rate.Methods: Retrospective analysis of clinical records of all patients with TA submitted to RAIT between 2008 and 2015. The influence of demo...

Context: T regulatory type 1 (Tr1) cells are a subpopulation of T lymphocytes (CD4+CD49+LAG-3+IL-10+) lymphocytes that exerts a significant immunosuppressive effect. However, its possible role in autoimmune thyroid disease (AITD) had not been explored so far.Objective: To analyze the levels and function of Tr1 cells in peripheral blood and thyroid tissue of patients with AITD.Design: Cases and controls, observational study.<p c...

Introduction: Graves’ orbitopathy (GO) is the most common extrathyroidal manifestation of Graves’ disease. The first-line treatment are intravenous corticoids in active moderate-severe GO. Tocilizumab is a humanized monoclonal antibody against the IL-6 receptor which has been approved for the treatment of rheumatoid arthritis and is in its research stage for patients with corticosteroid-refractory GO.Objectives: To assess the experience with to...

Pheochromocytoma (PCC) is a rare tumor that arises from the adrenal medulla, usually presents with headache, sweating and palpitations due to excessive catecholamine release. However, PCC may secrete neuropeptides, hormones and cytokines, such as interleukin-6 (IL-6)) resulting in unusual clinical manifestations. A 48-year-old woman with a previous history of type 1 neurofibromatosis (NF1) and hypertension was referred to discarded PCC. Laboratory tests revealed leukocytosis a...

IntroductionThe close relationship between cancer and thrombotic phenomena has been widely recognized and paraneoplastic organ infarctions may occur. Reports of papillary thyroid cancer associated to paraneoplastic phenomena are particularly scarce.Case reportA 39-year-old man with no prior relevant medical history was evaluated for acute onset of fever, malaise and mild pain referred to his left hypochondriu...

Background and objectivesTAS2R38 is a bitter taste gene that can influence food consumption depending on its single nucleotide polymorphisms (SNPs) leading to aminoacid substitutions in the receptor protein P49A (proline/alanine), A262V (alanine/valine) e V296I (valine/isoleucine). Subjects with at least one PAV (proline-alanine-valine) copy are bitter tasters, while AVI homozygotes are non-tasters. Other variants have intermediate bitter tasting: AAV&#6...

Introduction: Forkhead box E1 (FOXE1) gene encodes a transcription factor crucial for thyroid morphogenesis, differentiation, and function. We previously found evidence of the involvement of a rare germline FOXE1 variant in familial non-medullary thyroid carcinoma (FNMTC) etiology. FNMTC most common subtype is papillary thyroid carcinoma (PTC), and family members frequently present thyroid follicular nodular disease (FND). Germline FOXE1 mu...

Introduction: Thyroid fine-needle aspiration cytology (TFNA) is a widely used diagnostic method that is generally safe. Aiming to reduce haemorrhage doctors frequently advise patients to withdrawal antithrombotic/anticoagulant (AT/AC) drugs before TFNA. There are no guidelines recommending so and the so called ‘novel anticoagulants’ have been poorly studied in this context. Some patients are likely being exposed to increased thrombotic risk unnecessarily. Evidence is...

Introduction: Central diabetes insipidus (DI) is a frequent complication of transfenoidal surgery for Cushing’s disease (CD). It can be transient or, more infrequently, permanent. The most common mechanism results from surgical neurohypophyseal damage rather than local mass effect from the pituitary adenoma.Case report: A 40 years old woman was referred to our Endocrinology outpatient clinic at the beginning of 2015 for new onset hypertension, signi...

Introduction: Acute Kidney Injury (AKI) is highly prevalent during hospitalization of patients with type 2 diabetes (T2D), and has been associated with increased risk of hypoglycaemia in Intensive Care Units. However, this association in non-critically ill patients is less clear and evidence on the impact of AKI’s severity and duration on hypoglycaemia is lacking.Objectives: To assess the impact of AKI and its severity and duration on the risk of hy...
