Isolated Vaginal Bleeding Before the Onset of Puberty.

Isolated vaginal bleeding before the onset of puberty is a rare presentation of isosexual precocity. In most cases, isolated vaginal bleeding without an abnormal genital examination is self-limited with resolution usually within 1 to 3 episodes. Watchful waiting is appropriate in most patients who do not have persistent bleeding, other signs of puberty, or signs/symptoms of an underlying etiology.

Premature Pubarche: A Pragmatic Approach.

Premature pubarche (PP) is a common and usually benign variant of normal puberty most often seen in 5-year-old to 9-year-old children. Some providers routinely order laboratory testing and a bone age to try to rule out other diagnoses including nonclassic congenital adrenal hyperplasia and gonadal or adrenal tumors. I review the natural history of PP and studies which suggest that without clinical features such as rapid growth and progression or genital enlargement, it is unlikely that a treatable condition will be found.

Females with Breast Development before Three Years of Age.

Breast development in a girl 3 years of age or younger is a commonly encountered scenario. Nearly all of these cases will either regress or fail to progress during follow-up, confirming a diagnosis of premature thelarche (PT). Studies show that these girls will have onset of true puberty and menses at a normal age.

Gonadotropin-releasing hormone analog therapies for children with central precocious puberty in the United States.

Gonadotropin-releasing hormone agonists (GnRHa's) are the standard treatment for children with central precocious puberty (CPP). We aim to present data on available GnRHa options with an easy-to-review table and discuss factors that influence treatment selection. Five GnRHa's are currently FDA-approved and prescribed in the US and published data suggest similar safety and efficacy profiles over the first year of treatment.

Economic burden of growth hormone deficiency in a US pediatric population.

Pediatric growth hormone deficiency (GHD) is a rare disorder of short stature that is currently treated with daily injections of somatropin. In addition to short stature, GHD is associated with other comorbidities such as impaired musculoskeletal development, cardiovascular disease, and decreased quality of life. To analyze somatropin utilization, adherence, and health care costs among children with GHD who had either Medicaid or commercial health insurance.
