NONACCIDENTAL HEAD-INJURY IN CHILDREN

Aims: To analyse the clinical features, social circumstances, investigations and outcome of 49 children with significant non-accidental head injury admitted to The Prince of Wales Children's Hospital between 1979 and 1993. Clinical features: Age ranged from one month to eight years, with 30 children less than one year old. There were 28 boys and 21 girls. Thirty-three were in the care of a parent. Eleven of these were known to the Department of Community Services and 22 were from families with stressed socioeconomic circumstances characterised by deprivation. In 44 cases the history was incompatible with the clinical findings. On admission, 21 had marked depression of awareness, with a Glasgow Coma Scale score (GCS) of 9 or less. Eleven of this group were fitting. Seizures were present in a further 13 children who were semi-purposeful (GCS > 9). Twenty-eight had retinal haemorrhages and 35 had soft tissue scalp contusions, 23 in association with skull fracture. Twenty-siz had associated injuries. Seven children died. Of the 42 survivors at the time of discharge, 19 had severe motor disability associated with other deficits. Twenty-four were returned to the care of their families. Conclusions: Retinal haemorrhage and unconsciousness on admission (GCS less than or equal to 9) were positively associated with a poor outcome (P<0.001 and 0.002, respectively). Cerebral oedema found on computerised tomography was positively associated with severe motor disability on discharge (P<0.001). Lowest socioeconomic circumstances appeared to be a risk factor for occurrence of injury: 22 of 49 children came from circumstances of deprivation.
