A 17-year-old patient with a small paratesticular embryonic sarcoma presented with symptoms of renal failure, polyuria and widespread bone metastases. Investigation revealed hypercalcaemia and uraemia without any evidence of hyperparathyroidism. The hypercalcaemia responded over a period of weeks to administration of mithramycin with initial improvement in the symptoms and metabolic derangements. Control was lost with the necrosis of intra-abdominal tumour deposits and haemorrhagic polypoid deposits in the alimentary tract. The value and hazards of mithramycin are well demonstrated by these rare complications of this type of tumour.

In the 6-year period from 1983 to 1988, 12 infants (less than 24 months of age) and 103 children (2 to 14 years of age) were killed in road crashes in South Australia. This represents an annual incidence of 6.4 deaths per 100,000 children at risk. At least 4 other children were killed in off-road vehicle-related accidents. Of these deaths, approximately half were car passengers, one third pedestrians, and one sixth pedal cyclists. Most of these infants and children died at the accident site or soon after, but 26 of them survived long enough to be admitted to hospitals with neurosurgical units and an audit of these patients suggests that there were at least 3 preventable deaths. However, autopsies of 78 patients show that the great majority of these deaths resulted from devastating brain and/or trunk visceral injuries. Better emergency care and the use of neurosurgical retrieval teams may save some lives. But more lives might be saved by the use of appropriate restraints for infants and children in cars, by reducing the exposure of child pedestrians and cyclists to road traffic, and by mandatory use of helmets by child cyclists. Off-road vehicular accidents are not as a rule included in road crash statistics; the practice of giving small motorcycles to young children has created a new category of vehicular accidents sometimes causing severe head injury.
