Gonadotropin-releasing hormone ana-logues (GnRHa) are used to treat central precocious puberty. They also are used to delay puberty in short children with a prognosis for impaired adult height. In both cases, growth hormone (GH) treatment is sometimes added. To determine how North American pediatric endocrinologists are using the combination of GH and GnRHa, we searched the National Cooperative...

OBJECTIVES Idiopathic central precocious puberty and its postponement with a (gonadotropin-releasing hormone) GnRH agonist are complex conditions, the final effects of which on bone mass are difficult to define. We evaluated bone mass, body composition, and bone remodeling in two groups of girls with idiopathic central precocious puberty, namely one group that was assessed at diagnosis and a se...

The objectives of this study were to determine the incidence of precocious puberty and effect of exposure to a bull on the incidence of precocious puberty in beef heifers. The experiment was conducted using 120 heifers during 1990 and 1991. Heifer calves were randomly assigned to be pastured in the presence (n = 30 heifers/yr) or absence (n = 30 heifers/yr) of a bull starting at 140 +/- 14 d of...

OBJECTIVE Precocious puberty leads to discrepancies between physical and chronological age. The aim of the present study was to evaluate behavioral patterns and social competences in 34 girls with idiopathic precocious puberty. METHODS Height, body weight, and BMI were determined, and pubertal development was assessed. The Korean-child behavior checklist (K-CBCL) was completed by parents. R...

Growth in precocious puberty is a subject of concern to families and clinicians alike. The definition of precocious puberty and the role of obesity in the age of onset have also been areas of debate since the Lawson Wilkins Society recommended a lowering of the age of onset of precocious puberty in US girls. An understanding of growth patterns in normal children with earlier or later onset of p...

BACKGROUND It is important to differentiate central from peripheral causes of precocious puberty because of distinct management options. CASE CHARACTERISTICS 4 girls with discordant pubertal development. OBSERVATIONS All had low basal and GnRHa stimulated FSH and LH level with high estradiol level. Abdominal ultrasonogram helped in diagnosing precocious pseudopuberty- ovarian cyst in 3 chil...
