The rationale underlying the use of gonadotropin-releasing hormone analogues (GnRHa) to treat patients with central precocious puberty is reviewed. GnRHa are now considered the treatment of choice for patients with central precocious puberty, but the adult heights that these patients attain often fall short of what would be expected according to their genetic potential. This has led to investig...

Results The mean age at the start of treatment was 8.11 ± 0.70 years in group 1, 8.98 ± 0.38 years in group 2 and 9.46 ± 0.46 years in group 3, respectively. The mean predicted adult height (PAH) SDS at the start of treatment was -1.29 ± 1.16 in group 1, -1.14 ± 0.88 in group 2 and -1.87 ± 1.09 in group 3, respectively. Rate of growth during treatment with GnRHa combined with GH was higher sign...

To establish normative data and determine the value of fluorometric AutoDELFIA assays (Wallac Oy) in the investigation of precocious puberty, we determined serum levels of LH, FSH, testosterone, and estradiol under basal and GnRH-stimulated conditions in 277 normal subjects at various pubertal stages and in 77 patients with precocious puberty. A substantial overlap was observed in basal and GnR...

BACKGROUND Precocious puberty (PP) is defined as the appearance of secondary sex characteristic at an age <8 years in girls and <9 years in boys, or menarche <9 years in girls. OBJECTIVE To determine the etiologies and clinical characteristics of children presenting with PP. SUBJECTS AND METHOD The medical records of 307 children (292 girls, 15 boys) with PP (1995-2009) were reviewed. RES...

The GnRH analogue has been shown to be effective in the treatment of precocious puberty when given as a daily subcutaneous injection. We studied the effectiveness of a long-acting GnRH analogue, Triptoreline, for the treatment of central precocity, by suppressing gonadotropin and estradiol secretion in three children with true precocious puberty. One month after single dose intramuscular i...

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...

In this session students will evaluate data on precocious puberty and try to find its underlying causes. Read this to the class or discuss it in your own words with them. Be sure that you cover these points: what causes normal puberty; the technical terminology of puberty; is a statistically significant difference in average age at puberty of 3, or 6 months biologically significant? Emphasize t...

In boys, central precocious puberty (CPP) is the appearance of secondary sex characteristics driven by pituitary gonadotropin secretion before the age of 9 years. In the last years, relevant improvements in the treatment of CPP have been achieved. Because CPP is rare in boys, the majority of papers on this issue focus on girls and do not address specific features of male patients regarding end ...

Methods Twenty boys with ICPP were treated with GnRHa for (20. 0 ± 6. 1) months. At the beginning of therapy, mean chronological age and bone age was(11. 4 ± 1. 0) years and(13. 0 ± 0. 4) years, respectively. GnRHa was discontinued when the boys reached the chronological age and bone age of (13. 2 ± 1. 1) years and (13. 7 ± 0. 6) years, respectively. At the conclusion of the study, all the boys...

BACKGROUND Depot preparations of gonadotropin-releasing hormone agonists (GnRHa) are the gold standard drugs for the treatment of central precocious puberty. A concern about these drugs is obesity. OBJECTIVES This study aimed to investigate the effect of gonadotropin-releasing hormone agonists (GnRHa) therapy on body mass index (BMI) in girls with central precocious puberty (CPP). PATIENTS ...
