We investigated pubertal development of 4019 boys and 3562 girls >8 y of age participating in a cross-sectional survey in The Netherlands and compared the results with those of two previous surveys. Reference curves for all pubertal stages were constructed. The 50th percentile of Tanner breast stage 2 was 10.7 y, and 50% of the boys had reached a testicular(More)
Early puberty is not well defined in paediatric endocrinology. This chapter reviews the current insights on definitions, patient groups and treatment modalities in girls with early puberty. It is concluded that there is no clear evidence for a beneficial effect of gonadotrophin releasing hormone agonist (GnRHa) treatment in auxological terms. A clinical(More)
OBJECTIVE The small number of boys present in most studies on final height (FH) after gonadotropin-releasing hormone agonist (GnRHa) treatment for central precocious puberty (CPP) offers difficulties in the evaluation of the effects of treatment on FH in males. METHOD We therefore combined FH data from The Netherlands, Italy and France to study the effect(More)
We investigated pubertal development of 4019 boys and 3562 girls Ͼ8 y of age participating in a cross-sectional survey in The Netherlands and compared the results with those of two previous surveys. Reference curves for all pubertal stages were constructed. The 50th percentile of Tanner breast stage 2 was 10.7 y, and 50% of the boys had reached a testicular(More)
A 6-year-old girl was admitted to our hospital for excessive weight gain. On presentation, she had a typical Cushingoid appearance and hypertension. Laboratory analysis was indicative for an exogenous glucocorticoid source, showing values that were low for serum cortisol and adrenocorticotropin and for 24-h urinary glucocorticoid (metabolite) excretion.(More)
In rheumatic diseases the use of corticosteroids (CS), immobility, or the disease itself, may cause osteoporosis and growth retardation. We evaluated bone mineral density (BMD) by dual energy X-ray absorptiometry (DXA), growth and physical activity in 27 children with rheumatic disease, all treated with high dose CS for at least one year, in a(More)
OBJECTIVES To test the sensitivities of recently published American recommendations predicting occult intracranial lesion (OICL) in girls with central precocious puberty (CPP), and to validate a previously derived diagnosis rule predicting OICL based on age at puberty onset and estradiol (E2) level. STUDY DESIGN A retrospective, multicenter,(More)
In this review several aspects of gonadotrophin releasing hormone agonists (GnRHa) treatment in central precocious puberty (CPP) are highlighted. These include issues of the definition of precocity, assessment of CPP and thelarche variants. Indications for treatment with GnRH agonists are discussed, not only in CPP but also in children with other reasons to(More)
We assessed the effectiveness and safety of 3 yr combined GH and GnRH agonist (GnRHa) treatment in a randomized controlled study in children with idiopathic short stature (ISS) or intrauterine growth retardation (IUGR). Gonadal suppression, GH reserve, and adrenal development were assessed by hormone measurements in both treated children and controls during(More)
BACKGROUND Early onset of puberty is frequently observed in adopted children. During treatment with a gonadotrophin releasing hormone agonist (GnRHa), a decrease in height velocity (HV) precludes height gain. OBJECTIVE AND DESIGN We studied the effect of the addition of GH to GnRHa treatment in a 3-year prospective randomized trial in 30 adopted children(More)
