Popis: We have performed a mixed longitudinal study of 59 spontaneous (24hr profiles) and stimulated (insulin-induced hypoglycaemia tests - ITT) measures of growth hormone (GH) secretion in 35 prepubertal children aged 1.5 to 11.2 years with BT distant from the hypothalamo-pituitary area before and at 6-12 monthly intervals up to 3 years after surgery ± radiotherapy ± chemotherapy. We have compared results with those obtained in 26 short normal controls (SN). The profiles were analysed by a distribution method. We observed discrepancies between peaks of spontaneous and stimulated GH in BT but not SN. The ratio was significantly greater in all BT groups compared to SN (p
