Sex hormone-binding globulin (SHBG) carries sex steroids in blood regulating their bioavailability. Red wine consumption increases plasma SHBG levels, and we have discovered that resveratrol, a polyphenol enriched in red wine, acts specifically through the human constitutive androstane receptor (CAR), a drug/xenobiotic detoxification gene regulator, to increase hepatic SHBG production. Chromatin immunoprecipitation and luciferase reporter gene assays show that human CAR binds ...

Non-thyroidal illness syndrome is the alteration in thyroid function tests (TFTs) that occurs in critically ill patients, including those using thyrotoxic medications. Therefore, it is a challenge to interpret thyroid function tests in a critically ill patient on amiodarone. Case of 66-year-old male with history of heart failure with reduced ejection fraction, atrial fibrillation, and hypertension who presented to the emergency room due to progressive shortness of breath. Phys...

Introduction: Knowing that only in 5–15% of FNABs the pathological analysis shows malignancy, enhance diagnostic accuracy is needed. The use of the TIRADS score and a revised version proposed by the British Thyroid Association (BTA) intend to determine if a FNAB should be performed or not in the evaluation of nodular goitre.Objective: To determine whether an adequate correlation is present between the risk category assigned to the nodules studied un...

Introduction: Therapeutic approach of patients (pts) with metastatic renal cell carcinoma (mRCC) may include the use of biological agents such as m-TOR inhibitors: temsirolimus (TM) and everolimus (EV). Its use is associated with metabolic dysfunction, especially with everolimus: hyperglycemia (37% TM treated pts vs 72% EV treated pts), hypercholesterolemia (25% TM treated pts vs 81% EV treated pts) and hypertriglyceridemia (30% TM treated pts vs 73% EV treated pts). Discontin...

Introduction and objective: The pregnancies in women with pregestational diabetes are associated with increased risk of abortion, birth defects, complications of pregnancy and perinatal morbidity and mortality. Pregnancy planning would be associated with better metabolic control, and therefore better obstetric and perinatal outcomes. The objetive of this study has been to evaluate the obstetric results of women with pregestacional type 1 diabetes and compare planned with not p...

Introduction: The aim of this study was to evaluate effects on glycemic control, body weight and cardiovascular risk factors (BP, lipids and Epworth sleepiness scale) in diabetic patients with morbid obesity treated with exenatide.Material and methods: We studied consecutively 21 T2DM patients, all of them treated with metformin full dosage and insufficient metabolic control referred to our clinic for preoperative control of bariatric surgery. Twelve of ...

Introduction: Sterotactic radiosurgery (SR) has been used to treat recurrent adenomas and also as a primary treatment. The objective is to evaluate long-term tumor control, development of hypopituitarism and other side effects in the follow-up.Patients and method: Retrospective analysis of 21 patients with non-functioning pituitary adenomas (NFA) treated with modified linear accelerator (LINAC) between 1998 and 2009 in three tertiary Spanish hospitals. C...

Introduction: Sterotactic radiosurgery (SR) has been used to treat recurrent adenomas after failure of medical and surgical procedures and also as a primary treatment. The aim of this paper is to evaluate long-term control of functioning pituitary adenomas (FPA).Patients and method: Thirty-eight patients with FPA treated with modified linear accelerator (LINAC) between 1998 and 2009 in three tertiary Spanish hospitals. Hormonal control was defined as hor...

67 y/o old female, with long history of hyperthyroidism, without treatment and hypertension. Two months prior to admission, she received amiodarone 200 mg daily due to cardiac arrhythmia. One week prior to admission, she developed symptoms of Congestive Heart Failure and weight loss. Family history: hyperthyroidism in two sisters. Physical examination: acutely ill, thin female, in moderate respiratory distress. Alert, oriented x 3.BP: 155/119 mmHg HR: 150.Prominent findings: m...

Introduction: Recent studies have shown that chronic lymphocytic thyroiditis is associated with increased risk of developing papillary thyroid carcinoma (PTC). Although still controversial, these carcinomas appear to have a better prognosis. This study aims to evaluate the presence of thyroiditis in thyroids with PTC and the association with histological variables of prognostic value, Tg and evidence of metastasis in 131I scan.Methods: Descrip...
