The conclusion of Panayiotopoulos that glucocorticoid resistance accounted for 57% to 67% of their premature adrenarche and polycystic ovary syndrome cases cannot be accepted from the data presented. This is because proper validation of their method for determining glucocorticoid sensitivity is not presented. Furthermore, the method seems insensitive to physiologic glucocorticoid concentrations.

Background: Premature adrenarche (PA) has been reported as a potential precursor of metabolic disease. We aimed to explore the interaction between body composition and cardiometabolic health of prepubertal children with PA.
Methods: This observational study comprised of 87 children with PA (15 boys, 8.
Introduction: Premature adrenarche in girls is defined biochemically by an increase in adrenal androgen (DHEAS) levels above the age-specific reference range before age 8 years. Recently, increased levels of 11-oxyandrogens have also been reported in girls with premature adrenarche. Epigenetic modifications, specifically CpG methylation, may affect gene expression and/or activity of steroidogenic enzymes during developmental changes in adrenal androgen secretion.

Objective: High concentrations of dehydroepiandrosterone sulfate (DHEAS) often precede premature puberty and sometimes polycystic ovary syndrome (PCOS). We hypothesized that the underlying mechanisms might involve DNA methylation. As an indicator of the downstream effects of DHEAS, we looked for associations between prepubertal DHEAS concentration, pubertal progression, and DNA methylation at puberty-related genes in blood cells.

Newborns who do not reach a weight appropriate for their gestational age and sex can be classified in different ways. This article defines the concepts of small for gestational age (SGA) and intrauterine growth restriction, as well as the underlying causes of these conditions, with the goal of establishing consensus definitions for these patients, in whom treatment with growth hormone throughout childhood may be indicated and who may be at risk of developing endocrine or metabolic disorders in puberty and adulthood. Most SGA children experience spontaneous catch-up growth that is usually completed by age 2 years.

Background: Girls with premature adrenarche (PA) mature earlier than peers and have been found to have greater symptom accounts reflecting anxiety compared to peers. It is not known, however, whether PA effects cognitive development. This longitudinal case-control cohort study aimed: (1) To investigate whether a history of PA leads to measurable changes in adulthood cognitive performance, and (2) to assess whether findings characteristic of PA girls predict adulthood cognitive performance.
