Acquired transverse myelopathy in children in the United Kingdom--a 2 year prospective study.
OBJECTIVE
To define the incidence, describe presentation, management and outcome and identify prognostic factors in Acquired Transverse Myelopathy (ATM) in children under 16 years.


METHODS
A prospective population-based surveillance study, involving all consultant paediatric neurologists in the United Kingdom from 1 July 2002 to 30 June 2004.


CONCLUSIONS
Response rate was 91%, and 60 children were reported, of whom 41 were included. Median age was 9 years. The incidence of ATM in children under 16 years in confirmed cases is at least 1.72 per million children per year. There was a previously unrecognised male predominance (M:F 25:16). Early evaluation of bladder function is sometimes omitted. MR imaging should include whole spine and brain to maximise diagnostic information. Despite the use of high dose steroids, 25% of cases were left with significant sequelae. Outcome data was available for 36 children in whom recovery was defined as 'complete' in 19, 'good' in 8, 'fair' in 3 and 'poor' in 6. Significant positive prognostic factors were preceding infection, start of recovery within a week of onset, age less than 10 years, and lumbosacral spinal level on clinical assessment. Significant negative predictors were flaccid legs at presentation, sphincter involvement and rapid progression from onset to nadir within 24h.
