Prevalence and predictors of abnormal liver enzymes in young women with anorexia nervosa.

Objective: To determine the prevalence and predictors of abnormal liver enzyme levels in ambulatory young women with anorexia nervosa (AN).

Study Design: In this cross-sectional study of 53 females with AN, serum concentrations of liver enzymes and hormones were measured. Anthropometric, dietary, and body composition information was collected.

Normal ovarian structure and function with normal glucose tolerance in girls with early treatment of classic congenital adrenal hyperplasia.

Unlabelled: Hyperandrogenism and hyperinsulinism have both been suggested as etiologic factors behind functional ovarian hyperandrogenism or polycystic ovary syndrome. Females with congenital adrenal hyperplasia provide a clinical model to evaluate the contribution of pre- and post-natal hyperandrogenism on ovarian structure and function.

Study Objective: To evaluate glucose tolerance, and structure and androgen production of the ovaries in young females with classic congenital adrenal hyperplasia.

Bone mineral status in children with congenital adrenal hyperplasia.

Congenital adrenal hyperplasia (CAH) is caused by a deficiency in an adrenal enzyme resulting in alterations in cortisol and aldosterone production. Bone status is affected by chronic glucocorticoid therapy and excess androgen exposure in children with CAH. This cross-sectional study enrolled participants with 21-hydroxylase deficiency from a pediatric referral center.

Skeletal measurements by quantitative ultrasound in adolescents and young women with anorexia nervosa.

Objective: To compare quantitative ultrasound (QUS) measurements in adolescents with anorexia nervosa (AN) with that in healthy control subjects and to determine the utility of QUS as a tool to evaluate skeletal status in these patients.

Study Design: Female adolescents with AN (n = 41) and healthy control subjects (n = 105) were recruited. Speed of sound (SOS) was measured at the radius and tibia.
