Prevalence of Testicular Adrenal Rest Tumor and Factors Associated with Its Development in Congenital Adrenal Hyperplasia.

Background: Testicular adrenal rest tumors (TART) can cause infertility in congenital adrenal hyperplasia (CAH) males.

Aims: To determine TART prevalence in patients with CAH due to 21-hydroxylase deficiency (21-OHD) and evaluate possible factors associated with its development.

Methods: This is a descriptive and analytical cross-sectional study evaluating males with the classical form of 21-OHD through testicular ultrasonography and serum inhibin B dosages.

Fine motor skills and expressive language: a study with children with congenital hypotyreoidism.

Purpose: To screen the global development of children with and without congenital hypothyroidism and to investigate the association between fine motor skills and expressive language development in both groups.

Methods: This is a prospective study of a cohort of children diagnosed with Congenital Hypothyroidism and monitored in a reference service for congenital hypothyroidism of a public hospital and of children without this disorder. The screening was performed using the Bayley Scales of Infant Development III in the cognitive, gross and fine motor skills, and receptive and expressive language domains.

Accuracy of anthropometric measurements in estimating fat mass in individuals with 21-hydroxylase deficiency.

Objective: The use of anthropometric measurements to estimate the percentage of body fat (%BF) is easy and inexpensive. However, the accuracy of these methods in patients with 21-hydroxylase deficiency (21OHD) has not been explored. The objective of this study was to evaluate the accuracy of skinfold-based models, body mass index (BMI), and waist circumference (WC) in estimations of %BF using dual-energy X-ray absorptiometry (DXA) as the reference method in individuals with 21OHD.
