متن کاملPremature Thelarche in Later Childhood Demonstrates a Pubertal Response to GnRH Stimulation Test at One Year after Breast Development
Premature thelarche in later childhood (such as at 5-7 yr of age) is not always easy to distinguish from GnRH-dependent precocious puberty. In this study, a GnRH stimulation test was performed on 21 girls from 5 to 7.5 yr of age with early breast development. In 8 of 11 girls within 1 yr after thelarche, i.e., breast development, the GnRH stimulation test showed a prepubertal response, and in a...
متن کاملPlasma Kisspeptin Levels in Newborn Infants with Breast Enlargement
OBJECTIVE Kisspeptin levels have been reported in children with premature thelarche, precocious puberty and adolescent gynecomastia, but there are no reports on kisspeptin levels in the neonatal period. This study aimed to investigate plasma kisspeptin hormone levels in newborns with and without breast enlargement. METHODS Plasma kisspeptin levels and other related biochemical variables were ...
متن کاملSerum luteinizing hormone and follicle stimulating hormone in normal children and patients with various clinical disorders.
Serum concentrations of luteinizing hormone (LH) and follicle stimulating hormone (FSH) were determined in 329 normal children and 185 individuals with endocrinological abnormalities or variations of development. A significant increase of gonadotrophins is noted at the onset of puberty among the boys and at menarche for girls. The values are compared with serum concentrations of LH and FSH in c...
متن کاملPremature thelarche: clinical and laboratorial assessment by immunochemiluminescent assay.
In order to establish cut-off limits and to distinguish isolated premature thelarche (IPT) from precocious puberty (PP), we evaluated data from 79 girls with premature thelarche, comparing basal and stimulated LH and FSH serum concentrations with those from 91 healthy girls. A GnRH stimulation test was performed in 10 normal girls and in 42 with premature thelarche. Comparison among groups was ...
