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...

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...

Background: Body fat distribution is associated with obesity-related disorders. Promoting subcutaneous fat proliferative expansion can reduce visceral fat ectopic deposition and the risk of obesity-related insulin resistance, hepatic steatosis, and cardiometabolic diseases. Argonaute 2 (Ago2) was found to mediate RNA silencing in the liver to regulate obesity-related energy metabolism, while its role in fat adipose tissue storing excess energy has not been add...

Objective: To investigate the feasibility and rationality of letrozole (Lz) as treatment for severely advanced bone age (BA) in children with 21-Hydroxylase Deficiency (21-OHD).Methods: This was a retrospective self-control study to test the possibility of Lz that a decrease in the rate of bone maturation and an increase in predicted adult height (PAH).Results: The improvement of h...

Background: Girls diagnosed with central precocious puberty (CPP) or early and fast puberty (EFP) tend to exhibit temporarily rapid acceleration in growth due to increased sex hormone production or exposure, leading to premature closure of the growth plate and a shorter final adult height (FAH). Rapid progression of the secondary sexual characteristics in children can also cause poor social adaptability, psychological stress, and emotional disorders. CPP/EFP c...

Objective: To explore the clinical and molecular genetic characteristics of congenital lipoid adrenal hyperplasia (CLAH), and to sequence the acute regulatory protein (steroid acute regulatory, StAR) gene of the infant patient and her pedigree.Methods: Physical examination, laboratory tests, and imaging examination of the 1-month- old patient with CLAH were collected. DNA was extracted from blood samples of the patient a...
