Introduction and objectives: A possible increase in blood pressure (BP) and other cardiovascular risk factors has been associated with testosterone treatment (TT) in female-to-male transsexuals (FMT). Nonetheless, the available evidence does not support an increase in CV morbidity or mortality. We set out to analyze the impact of TT on BP and lipid profile in a cohort of FMT patients.Methodology: Retrospective observational study with no control group in...

Introduction: In addition to the medication prescribed by their doctors, patients may recourse to natural medicine and take herbal medications without thinking about their potential side effects and interactions with other drugs.Case Report: A 39-year-old female, with personal history of iron deficiency anemia, regular menses but long-standing dysmenorrhea and polymenorrhea and reactive anxiety-depressive disorder, complained of frequent intermenstrual s...

Background: Insulin-related peptides are found in Cnidaria (the most ancient animals with differentiated tissues including a nervous system, dating from 600 million years ago) and their nucleotide sequence has been highly preserved ever since. In mammals the binding of insulin to its receptor causes a cascade of actions, the main one being translocation of GLUT4 glucose transporters to the plasma membrane allowing influx of glucose into the adipose and striated muscle cells. B...

Background: The prolactin/vasoinhibin axis constitutes a novel endocrine axis in which the generation, secretion, and actions of the pituitary hormones prolactin and vasoinhibins are under control of the hypothalamus, the pituitary gland, and of regulators in the target tissue microenvironment. Vasoinhibins are generated in the pituitary gland and in multiple target tissues through proteolytic cleavage of prolactin; it is not known wether they are also produced in the circulat...

Introduction and objectives: Testosterone therapy (TT) in female-to-male transsexuals (FMT) usually causes cessation of menses within the first few months. However the changes in the hormonal profile are not well known. We set out to analyze the hormonal changes and menstrual evolution in a cohort of FMT who began TT.Methodology: Retrospective observational study with no control group in a cohort of 34 FMT patients who started TT following a standard pro...

Background: Graves’ disease (GD) and Hashimoto’s thyroiditis (HT) are common disorders with an autoimmune etiology, which are known as autoimmune thyroid diseases (AITD). A specific seasonal pattern of the month of birth has been suggested in several autoimmune disorders, supporting the hypothesis of a link between viral infections and the development of aberrant immune-regulatory mechanisms. However, there are few studies which specifically address this issue in AIT...

Introduction: Endocrine Illnesses have high prevalence on a global level due to multiple etiologies that can lead alterations to this system.Objective: Determine the epidemiological profile of hyperthyroid and hypothyroid patients that receive endocrinological services from a medical institution in Medellin (Colombia) between 2013 and 2015.Methodology: A descriptive, retrospective study was conducted and included the clinical recor...

Introduction: Follicular tumours of the thyroid gland include benign follicular adenomas, follicular carcinomas and the follicular variant of papillary carcinoma. Although, molecular markers are a promising area of research to differentiate thyroid neoplasms, there is ample room for improvement in the research and clinical applications in this field. Furthermore, the final diagnosis requires thyroid lobectomy. The present study examined whether a differential protein expressio...

Introduction: Brain-derived neurotrophic factor (BDNF) is a protein that has been linked to several cardiovascular risk factors and bone status. Stress and corticosteroid exposure can affect BDNF levels, although this has never been studied in Cushing’s syndrome (CS). The aims of this study were to establish if BDNF levels were reduced in CS and to check possible associations to cardiovascular risk factors and bone status.Methods: 52 patients (18 ac...

Introduction: Diabetes mellitus is a condition on the increase, carrying a high risk of cardiovascular complications. It is, also, well known that diabetes confers a substantial burden of microvascular disease. Previous studies suggest a link between microvascular and macrovascular events in diabetes. However, just a few studies have investigated whether the presence of previous cardiovascular events is associated with microvascular disease in diabetes patients. So, this is th...
