This study aimed to identify variables involved in gender identity and sexual orientation, as well as to evaluate the professional and psychosocial aspects and quality of life in adulthood of a large cohort of patients with 46,XY and 46,XX DSD followed by a multidisciplinary team in a tertiary public hospital in Brazil. The study was mainly retrospective and comprised 151 DSD patients; 55 patients had 46,XX and 96 had 46,XY karyotypes. Etiological diagnosis of DSD was establis...

Abstract: Congenital hypogonadotropic hypogonadism (CHH) is characterized by isolated GnRH deficiency in the absence of central anatomical causes. Classically considered to be a permanent disorder, CHH reversal has been reported in up to 15% of cases. However, reversal may not always be life-long, as hypogonadism relapse can occur in a subset of patients. Criteria for reversal normalization of circulating sex steroids, and spontaneous fertility. We report a 26-yrs-old man, who...

Adrenocortical Carcinoma (ACC) is a rare and lethal disease with a poor prognosis. This study aims to share our 41-year experience as a referral center, focusing on identifying risk factors associated with ACC mortality. Our retrospective analysis included a cohort of 150 adult patients with ACC in all stage categories, treated between 1981 and 2022. Tumor hormonal hypersecretion was observed in 78.6% of the patients, and the median age of diagnosis was 40 years. The majority ...

Introduction: Effects of prior exposure to testosterone (T) during puberty on the performance of transgender women (TW) in estrogen therapy undergoing physical effort are not known, mainly about cardiopulmonary capacity (CPC). Objectives: To evaluate CPC and muscle strength in TW undergoing long-term gender-affirming hormone therapy (GAHT). Methods: A cross-sectional study was carried out with 15 TW (34.2±5.2 yo), 13 cisgender men (CM) and 14 cisgender women (CW). TW were i...

Whilst several key genetic contributors to the phenotype of central precocious puberty (CPP) have been recognized, many familial cases remain without a clear genetic aetiology. Methyl-CpG-binding protein 2 (MECP2) is a chromatin-associated transcriptional regulator, which plays an essential role in neuronal maturation. It is encoded by the MECP2 gene, located at chromosome Xq28, which is highly expressed in brain tissues. Loss-of-function mutations in MECP2 are usually associa...

Background: Congenital adrenal hyperplasia (CAH) is a rare condition that is associated with life long risk of adrenal crisis. Management of CAH demands a fine balance between excess glucocorticoid leading to adverse effects and too little glucocorticoid risking adrenal crises. Frequent occurrence of sick day episodes warrants dose adjustment and education regarding adrenal crisis. In a condition such as CAH it is difficult to collect sufficient data from small cohorts at a si...

Introduction: Masses in adrenal topography have been diagnosed frequently due to more available access to radiological imaging. Adrenal incidentalomas occur around 5% to 7% of patients undergoing abdominal imaging mainly over 50 years of age. The HCFMUSP is a complex tertiary center, a national reference to adrenal disorders and since 2006 around 300 adrenalectomies were performed; 8% of them corresponded to undetermined masses in adrenal topography.Obje...

Background: Adrenal insufficiency (AI) results from deficient production/action of glucocorticoids (GCs), with or without deficiency of mineralocorticoids (MC) and adrenal androgens. GC treatment is essential but some patient needs MC therapy to allow sodium(Na+) retention, potassium(K+) excretion and to maintain normal plasma volume and blood pressure. Much attention has focused on optimization of GC replacement but no consensus exists for optimization o...

Context: The role for hormone parameters at adrenal venous sampling (AVS) in predicting clinical and biochemical outcome remains controversial.Objective: To investigate the impact of hormone parameters at AVS under cosyntropin stimulation on lateralization and on complete biochemical and clinical outcome.Methods: We retrospectively evaluated 168 sequential AVS under cosyntropin infusion. Bilateral successful cannulation rate was 83...
