Introduction: Precocious pubarche is defined as pubic hair onset before age eight in girls and age nine in boys. In 5–20% of cases the cause is late-onset congenital adrenal hyperplasia (LO-CAH), which is due mainly to non-classic 21-hydroxylase deficiency. If not promptly diagnosed, it can lead to accelerated bone maturation, short final height, and in adulthood to severe acne, hirsutism and infertility.Case report: Adolescent male, 15 years-old, h...

Arterial hypertension usually results from the deregulation and hyperactivity of the renin angiotensin-aldosterone system. One of the available therapeutic approaches for its treatment is the use of mineralocorticoid receptor (MR) antagonists, thus blocking aldosterone action.The aim of this study was to characterize the effects of spironolactone and eplerenone, on the morphology of the adrenal gland of spontaneously hypertensive (SHR) and normotensive (...

Introduction: The majority of adrenocortical carcinomas (ACC) autonomously produce steroids. However, urinary steroid profile of patients with ACC revealed that these tumors secrete and release predominantly intermediate metabolites. This steroid secretion pattern could be attributed to the undifferentiated status of the tumor cells expressing an incomplete pattern of enzymes involved in the steroidogenic cascade.Aims: Our study aim was to analyze the ex...

Introduction: Thyroid nodules in children and adolescents are less prevalent, but entail greater risk of malignancy than in adults. Most are asymptomatic because they are associated with normal thyroid function, but their prevalence is increasing due to the incidental diagnosis by neck ultrasound.Aims: To evaluate the characteristics of a pediatric population with thyroid nodules submitted to fine-needle aspiration (FNA) biopsy.Met...
