A population-based study of children with cerebral tuberculosis in New South Wales.

OBJECTIVE: To determine the incidence of childhood cerebral tuberculosis (tuberculous meningitis [TBM] and tuberculoma) in a defined population. DESIGN: Retrospective, population-based study. SETTING AND PARTICIPANTS: All resident children aged up to 14 years in New South Wales diagnosed with cerebral tuberculosis, from 1982 to 1996. MAIN OUTCOME MEASURE: Population-based incidence of childhood TBM. RESULTS: 10 children with TBM and one with tuberculoma were identified in the 15 years. The incidence of TBM was 0.053 (95% CI, 0.025-0.097) per 100,000. Eight of the 10 TBM patients were born in Australia and five were of white European origin. Only one had been vaccinated with BCG vaccine. Three of the children died. CONCLUSIONS: The incidence of childhood TBM in New South Wales is low, and comparable with that in other First World countries.

Respiratory function parameters in infants using inductive plethysmography.

A signal processing technique has been developed to determine respiratory function parameters by processing displacement data obtained from the abdomen and the rib cage of infants using respiratory inductive plethysmography. The technique transforms time-variant signals into the frequency domain, where they are filtered to reduce unwanted signal components. The phase relationship between the abdominal displacement and the rib cage displacement is determined from the phases of the filtered signals. Flow-volume loops, which are currently of great interest in respiratory medicine, are obtained from waveforms representing respiratory tidal flow and respiratory tidal volume. The index of respiratory timing is determined from a waveform representing respiratory tidal flow. The technique has been verified by statistical comparison with data simultaneously obtained using pneumotachography in a clinical study involving 49 infants.
