The objectives of treatment for children with central precocious puberty (CPP) are to avoid psychosocial problems caused by early pubertal development and to normalize adult height (AH). A long-acting GnRH analog is the treatment of choice for CPP. GnRH analog administration effectively arrests further development of secondary sex characteristics, slows bone age (BA) maturation, increases puber...

We have recently discovered ethyl 4–(2–benzylhexyloxy)benzoate (KF–13) as a novel anti–juvenile hormone (anti–JH) agent (Furuta et al., 2007). This compound induced precocious metamorphosis in larvae of the silkworm, Bombyx mori, a clear sign of JH deficiency, and its activity could be completely counteracted by the simultaneous application of methoprene, a JH agonist. Although KF–13 induced ob...

BACKGROUND McCune-Albright syndrome (MAS) is a rare non-inherited disorder characterized by the clinical triad of precocious puberty, cafe-au-lait skin lesions, and fibrous dysplasia of bone. CASE PRESENTATION We report a girl with MAS, presenting initially with vaginal bleeding at the age of 17 months. Ultrasonography revealed unilateral ovarian cysts and ureteral and ovarian enlargement. Co...

An attempt was made to identify the less severe cases of precocious puberty and to describe their natural course. A group of 17 girls with precocious puberty and a bone age advance over chronological age of less than two years (group 1) was compared with a group of 19 patients with severe precocious puberty and bone age advance of two years or more (group 2). Mean (SEM) plasma oestradiol concen...

We used a combination of immunohistochemistry and carbocyanine dye tracing to study neurons and their processes in the human embryonic forebrain, 4-7 weeks after conception, before the onset of synaptogenesis. We discovered a widespread network of precocious MAP2 (microtubule-associated protein 2)-immunoreactive cells, with long, nonaxonal processes, before the appearance of the cortical plate ...

Central precocious puberty, defined as the onset of puberty before the age 8 years in girls and 9 years in boys, results from a premature activation of gonadotropin-releasing hormone neurons in the hypothalamus. This condition is characterised by early pubertal changes, acceleration of growth velocity, and rapid bone maturation that often result in reduced adult height. It may be either idiopat...

Nineteen girls adopted from developing countries were referred for signs of idiopathic precocious puberty. After adoption, the catch up in linear and weight growth, together with improved nutritional and psychological conditions, may trigger the onset of puberty. Precocious puberty is a frequent and unnatural event in these girls. Treatment with gonadotrophin releasing analogues is indicated in...

McCune Albright syndrome is diagnosed by a constellation of Café-au-lait spots, multiostosis fibrous dysplasia and precocious puberty. Other endocrine dysfunctions which are often associated are growth hormone excess, hyperthyroidism, Cushings syndrome, hyperprolactinemia and phosphate wasting. Its prevalence is 1:100000–1:1000000 in different ethnicity [1]. It is a rare cause of precocious pub...

The incidence of sexual precocity is 1:10,000, yet previous puberty is infrequently reported. We report a unique case of a young child presenting to the Dermatology clinic for management of acne vulgaris and precocious puberty prompting further work-up to evaluate for McCune Albright Syndrome. While primarily idiopathic, we discuss the associated dermatologic conditions that should be considere...

C.v.B. is a girl who was born of psychopathic criminal and, in all probability, mentally subnormal parents. Her mental and physical development was backward from birth; at the age of 4 she could walk but did not speak. Earlier data are lacking. She stayed in several children's homes, and from the age of 9 she was in the Institution for Mentally Deficient Children in Noordwijk. At the age of 1 1...
