Introduction: The syndrome of late-onset hypogonadism (LOH) is a clinical and biochemical syndrome associated with advancing age male, characterized by typical symptoms and decreased serum concentrations of testosterone, which can affect multiple organ systems and may impair quality of life. The prevalence of LOH syndrome is higher in certain patient groups, obese, diabetic and suffering from erectile dysfunction manifest LOH at higher rates than the general population.<p ...

Introduction: During a normal menstrual cycle, serum levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol (E2), and progesterone (P4) can vary widely between cycles for the same woman, as well as between different women. Reliable reference values based on the local population are important for correct interpretation of laboratory results.Aims: To evaluate the discrepancy of the results on fertility hormones by two different t...

Introduction: In end-stage renal disease (ESRD), thyroid function tests are often abnormal, and their interpretation is not always straightforward. While haemodialysis (HD) procedure has well-established profound effects on the serum levels of a variety of molecules no such data have been published on thyroid hormones.Methods: In 110 ESRD patients, total and free thyroxine (T4 and fT4), total and free triiodothyronine (T3...

Introduction: Reference ranges for classifying a patient as hyper-, normo- and hypothyroidism vary from one laboratory to another, because the techniques used, regional factors (race, iodine..), but there is also the variables of age and sex of the patient are not taken. Article Thyroid Volume 21, Number 1, 2011, 5–11 Boucai et al, published equations to adjust the normal range in terms of these variables. Evaluate these equations and see if there are significant changes ...

Abstract: Obesity results from an imbalance between caloric intake and energy expenditure. Specialized neurons of the hypothalamus coordinately control the integration between feeding and thermogenesis and a defective regulation of these parameters contribute to the progressive accumulation of body fat. Recent studies have revealed that at least part of hypothalamic dysfunction contributing to the development of obesity results from the activation of a local inflammatory respo...

Leptin is an adipocyte-derived hormone that acts directly in the brain reducing food intake, increasing glucose uptake and modulating the metabolism in adipose tissue. Nevertheless, the central mechanisms related to improve glucose uptake, induced by leptin intracerebroventricular (icv), and the proteins activated in the skeletal muscle are incompletely understood. The aim of this study was to investigate the mechanism by which ICV leptin increase glucose uptake and improve gl...

Objective: Cardiovascular risk factors (CVRF) persist with notable prevalence in patients with Cushing’s disease (CD) after remission: obesity/overweight up to 40%, hypertension (HTA) up to 60%, type 2 diabetes (DM-2) up to 60% and dyslipidemia up to 30% of cases. Persistence of metabolic syndrome in patients with controlled CD seems to be related to the duration of the disease before remission. The aim of this study is to describe the prevalence of CVRF in patients with ...

IntroductionThe main role of vitamin D is regulating bone metabolism, but over the past years, the importance of vitamin D in non-skeletal actions has been studied. Vitamin D deficiency is very common in our environment. This deficit has been associated with higher risk of many chronic diseases, such as osteoporosis, hypertension, diabetes and even obesity. Recent evidence has demonstrated an association between low vitamin D status and autoimmune thyroi...

IntroductionToday, it is well recognized that disturbances in thyroid function may significantly affect mental status including emotion and cognition. Several studies have demonstrated the existence of a relationship between depression and hypothyroidism, although there is still no clear explanation of the pathophysiology that causes this association.ObjectivesTo assess whether there is a higher prevalence of...

Introduction: The initial clinical trials for teprotumumab excluded patients with previous orbital irradiation, surgery, glucocorticoid use (cumulative dose > 1gm), or biologic treatment. Therefore, information on the use of teprotumumab for patients who failed prior therapy is limited. Our purpose is to characterize the efficacy of teprotumumab for the treatment of recalcitrant TED.Methods: This is a multicenter retrospective study of all patients t...
