[Frequent growth disorders in puberty and adolescence]

About 50% of our patients with concern about their actual or final height are adolescents (girls greater than 11 years, boys greater than 13 years). Growth data of 103 adolescent patients (70 boys, 33 girls) seen in 1988/89 are analysed. 85% of the patients (90% of the boys) complained of short stature (length less than 3rd centile) whereas tall stature (height greater than 97th centile) was more frequently concerning girls (9 out of 16 patients). Genetic short stature and constitutional delay of growth and adolescence (CDGA) were most often diagnosed in short stature patients. When retardation of physical maturation is a major concern in patients with CDGA, treatment with a low dose of sex steroids leads to an acceleration of growth and pubertal development. This advancement of maturation is important for reducing the psychosocial difficulties of the concerned adolescents. Constitutional tall stature was the most frequent diagnosis in our tall adolescent patients. If predicted final height is above 185 cm for girls or 200 cm for boys the administration of height dose sex steroids (ethinylo-estraidol or conjugated oestrogen for girls, testosteron for boys) for height reduction can be tried, since a reduction in height between 3.5 cm and 7.9 cm has been reported for girls and similar data exists for boys. Nevertheless a cautious approach must be advocated for the administration of oestrogens because possible long term hazards can not yet be excluded.
