Background: In Brazil, specially in the south, there is a high prevalence of p53 mutations – 1:300 compared to 1:5000-1:20000 incidence worldwide. (1) As a consequence, adrenocortical carcinoma as a cause of virilization in children is much more common in our practice.Clinical Case: M.P.O., a 32-month-old girl, was referred to our institution - Hospital de Clínicas de Porto Alegre - in May 2022 due to progre...

Though most ophthalmologic emphasis has been stressed on the influence of retinopathy on the young diabetic community, lesser known is the complication of cataract, which has resulted in more than half of the blindness worldwide. This study attempts to stratify the epidemiology and risk factors of cataract in the type 1 diabetes mellitus (T1DM) population using data extracted from the National Health Insurance Research Database (NHIRD) in Taiwan.A two-st...

Background: Paediatric adrenocortical tumours (ACT) are rare and typically present with virilising symptoms and signs which can be similar to other virilising conditions such as congenital adrenal hyperplasia.Case description: We describe three cases of ACT diagnosed and managed at our institution over the past 10 years. The three girls presented with symptoms of virilisation. The mean interval between first symptoms and diagnosis was 19.6 months (rangin...

Androgen insensitivity syndrome (AIS) is a rare genetic disease caused by mutation in the androgen receptor (AR). The AR is an essential steroid hormone receptor that plays a crucial role in male sexual differentiation and development. Mutations in the AR gene on the X chromosome cause malfunction of the AR so that a 46,XY karyotype male shows some physical characteristics of a woman or a full female phenotype. Depending on the phenotype, AIS can be classified as complete, par...

Background: Patients with 46, XY DSD present conflicts and issues related to gender identity (GI) and change to male social sex in patients registered in the female social sex is not rare. The HTP test is a projective psychological test, which assesses aspects related to sexual identification. GI in this test is defined as female (F), male (M) or ambiguous.Objective and hypotheses: To evaluate GI in patients with 46, XY DSD by the HTP test and compare th...

Congenital hyperinsulinism (CHI) results from inappropriate insulin secretion most commonly caused by mutations in the ABCC8 and KCNJ11 genes which encode for the pancreatic β-cells-ATP-sensitive-potassium channel (KATP) subunits SUR1 and KIR6.2 respectively. Diagnosis of CHI is based on the presence of detectable plasma insulin during hypoglycemia, suppressed β-hydroxybutyrate and NEFA. Diazoxide is the major treatment for CHI, sirolimus had also b...

Objective: 21-hydroxylase deficiency (21-OHD) is the most common cause of congenital adrenal hyperplasia due to CYP21A2 gene mutation. The aim of study is to expand CYP21A2 mutational spectrum in the Chinese population and to provide novel genetic information in terms of ethnic diversity.Methods: 95 Chinese suspected 21-OHD patients with phenotypes varying from salt-wasting (SW) to nonclassic symptoms w...

DAX-1 is Dosage-sensitive sex reversal - Adrenal hypoplasia congenita critical region on the X chromosome 1, caused by mutation of NR0B1. It commonly presents X-Linked adrenal hypoplasia congenital, hypogonadotropic hypogonadism and infertility. However, we observed two patients whose testosterone elevated in their early infancy. Both of them are males with uneventful gestation and birth, and have a primary symptom as jaundice. For patient 1, poor feeding and pigment genital a...

Background: Data on the effect of cryptorchidism on hormones of androgen insensitivity syndrome (AIS) and 5alpha-reductase type 2 deficiency (5α-RD2) are still limited.Methods: We retrospectively evaluated 47 patients with AIS and 79 with 5α-RD2 to investigate the effect of cryptorchidism on hormone levels.Results: Anti-Müllerian hormone (AMH) levels in the AIS gro...
