Adult height in girls with idiopathic true precocious puberty.

GnRH analogs are used to suppress pituitary-gonadal activity in children with true precocious puberty. The indications for therapy in this situation are not established, as some girls have a slow evolutive form, and the capacity of GnRH analogs to preserve the adult height has not been evaluated. This study analyzes the growth and adult heights of 2 groups of girls with idiopathic true precocious puberty, 1 with a predicted height of 155 cm or less (group 1, 19 cases) and the other with a predicted height of more than 155 cm (group 2, 15 cases).

Predictive factors for the effect of gonadotrophin releasing hormone analogue therapy on the height of girls with idiopathic central precocious puberty.

The factors influencing the final height of central precocious puberty patients treated with gonadotrophin releasing hormone (GnRH) analogues remain a critical issue. This study compares the predicted final height before and after GnRH analogue therapy to identify predictive factors for final height. Fourteen girls with idiopathic central precocious puberty were treated with a GnRH analogue.

Idiopathic central precocious puberty in girls as a model of the effect of plasma estradiol level on growth, skeletal maturation and plasma insulin-like growth factor I.

Girls suffering from idiopathic central precocious puberty (CPP) may have different levels of estrogenic activity. This study was performed to evaluate the relationship between the estrogenic activity and the hypothalamopituitary activation and the effect of various plasma estradiol (E2) levels on growth, skeletal maturation and plasma insulin-like growth factor I (IGF-I). Fifty-eight girls with CPP were divided into 2 groups: group I with E2 less than 25 pg/ml (13 +/- 1 pg/ml, mean +/- SEM, n = 26) and group II with E2 greater than or equal to 25 pg/ml (52 +/- 3 pg/ml, n = 32).

Growth and endocrine disorders in optic glioma.

Hypothalamo-pituitary function in children with optic glioma may be impaired by the tumour itself and by the high cranial radiation doses used in treatment. This study evaluates the effect of optic glioma and its treatment on patient growth and pubertal development. Twenty-one patients (13 boys, 8 girls), treated for optic glioma by cranial irradiation (45-55 Grays) at a mean age of 5.

[Craniopharyngioma in children. Endocrine evaluation and treatment. Apropos of 37 cases].

Endocrine function was studied in 37 children treated for craniopharyngioma by total (22 cases) or partial (12 cases) excision and complementary or isolated irradiation (9 cases). Height deficiency was the only revealing sign in only 20% of cases. Skull X-rays showed patent abnormalities at the first examination in 36 of 37 cases.
