Validity of self-assessment of pubertal maturation.

Background And Objectives: Studies of adolescents often use self-assessment of pubertal maturation, the reliability of which has shown conflicting results. We aimed to examine the reliability of child and parent assessments of healthy boys and girls.

Methods: A total of 898 children (418 girls, 480 boys, age 7.

Determination of adrenal volume by MRI in healthy children: associations with age, body size, pubertal stage and serum levels of adrenal androgens.

Background: Adrenal disorders such as congenital adrenal hyperplasia result in abnormal adrenal size and morphology, but little is known about the clinical value of magnetic resonance imaging (MRI) in determining adrenal volume.

Objective: To evaluate the potential usefulness of MR methodology, to estimate adrenal size in healthy children and to evaluate determinants of adrenal volume such as age, gender, body size, pubic hair stage and serum levels of adrenal androgens.

Design: Two hundred and thirty-five healthy children (116 girls and 119 boys) (age range 10.

Current exposure of 200 pregnant Danish women to phthalates, parabens and phenols.

Many phthalates, parabens and phenols are suspected to have endocrine-disrupting properties in humans. They are found in consumer products, including food wrapping, cosmetics and building materials. The foetus is particularly vulnerable and exposure to these chemicals therefore is of concern for pregnant women.
