The use of anti-thyroid medication is favoured first line therapy in Graves’ disease (GD). However, relapse rates are high (up to 50%) and definitive therapies of either surgery or radioactive Iodine therapy (RAI) are often considered following an informed decision. The definitive choice taken depends on several factors considered during the patient-doctor interaction. The aim of this study was thus to determine the influence of such factors.A cross...

Background: Multiple endocrine neoplasia type 1 (MEN1) (OMIM 131100) is an autosomal dominant disorder associated with a high risk of developing parathyroid hyperplasia (90%), digestive neuroendocrine tumors (30–70%) and pituitary adenomas (30-40%). Prevalence of MEN1 is 2-10/100.000, there are no differences between men and women and usually, it is diagnosed before 40 years old. It is related to different mutations of the MEN1 tumour-suppressor gene (OMIM: 613733) which ...

Introduction: MODY 5 is a rare type of dominantly inherited diabetes mellitus. It is asociated with mutations of the hepatocyte nuclear factor-1beta (HNF-1beta) gene. They are mostly missense mutations that produce truncated proteins with a variable clinical spectrum that encompasses among others: kidney, genital and pancreatic abnormalities.Case-report: A 35 years-old man without relevant medical history, presented with acute hypergycemia (541 mg/dl) an...

Introduction: Medullary thyroid cancer (MTC) TNM classification categorizes lymph nodes (LN) according to their location, but does not consider number and size of LN.Objective: To analyze the relationship between number and size of LN in MCT persistent disease (PD).Material and methods: Retrospective study of patients with MTC followed up in a regional hospital from 1985 to 2015. The main variables (expressed as qualitative in freq...

Introduction: Roux-en-Y gastric bypass (RYGB) places patients at an increased risk of hypocalcemia due to the reduction in calcium absorption (because the procedure bypasses the duodenum and jejunum) and vitamin D deficiency. Subsequent thyroid surgery increases the risk of severe hypocalcemia due to potential post-operative hypoparathyroidism. Only a few cases have been published before of this kind of treatment-challenging hypocalcaemia.Case report: We...

Introduction: Diabetes mellitus is a condition on the increase, carrying a high risk of macro and microvascular disease. Previous studies suggest a link between microvascular and macrovascular complications in diabetes. However, just a few studies have investigated whether the presence of peripheral vascular disease (PVD) is associated with other macrovascular and microvascular complications in diabetes patients. So, this was the aim of our study.Patient...

Introduction: It is well known that diabetes confers a substantial burden of macrovascular disease. However, just a few studies have investigated the association between diabetic kidney disease (DKD) and cardiovascular disease. The purpose of this study is to investigate whether the presence of DKD is associated with macrovascular disease in diabetic patients.Patients and methods: 98 diabetic patients (48 males/50 females) were included in the study. DKD...

Purpose: A combined model of clinical, biochemical and radiological variables could help to predict autonomous cortisol secretion (ACS) in adrenal incidentalomas (AI).Methods: We analyzed retrospectively 100 patients diagnosed of AI between 2011 and 2015. AI was defined as an adrenal mass>1 cm, accidentally discovered by radiologic examination. ACS was ruled out (ACS-) by serum cortisol post-dexamethasone suppression test (Nugent) <3 μg/dl, ...

Background: Polycystic ovary syndrome (PCOS) is a common endocrine condition in women at reproductive age, in whom, glucose metabolism disturbances are commonly observed. In addition, overweight and obesity, especially visceral obesity, are more prevalent in PCOS women, which enhances the resistance to insulin action, and as consequence, the onset of impaired glucose tolerance (IGT) and/or type 2 diabetes mellitus (T2DM). Clinical guidelines recommend oral glucose tolerance te...

Introduction: Tyrosine kinase inhibitors (TKIs) are used for treatment of iodine-refractory differentiated thyroid cancer (DTC) in patients with progressive advanced disease.Sorafenib and lenvatinib are the TKIs currently approved for this indication.Objective: To describe the clinical experience in patients with iodine-refractory DTC treated with TKIs in our Institution.Materials and methods: Restrospective cohort study of patient...
