      This retrospective study calculated the cumulative radiation dose for children with cystic fibrosis (CF) attending a tertiary CF centre. Information on 77 children with a mean age of 9.5 years, a follow up time of 658 person years and 1757 studies including 1485 chest radiographs, 215 abdominal radiographs and 57 computed tomography (CT) scans, of which 51 were thoracic CT scans, were analysed. The average cumulative radiation dose was 6.2 (0.04-25) mSv per CF patient. Cumulative radiation dose increased with increasing age and number of CT scans and was greater in children who presented with meconium ileus. No correlation was identified between cumulative radiation dose and either lung function or patient microbiology cultures. Radiation carries a risk of malignancy and children are particularly susceptible. Every effort must be made to avoid unnecessary radiation exposure in these patients whose life expectancy is increasing.

      This study was carried out to assess if there was a difference in the Chest X- ray (CXR) report on recruited nurses carried out overseas and later repeated in Ireland. This study was carried out in two Irish teaching hospitals. The subjects of this study comprised all overseas nurses recruited in each of the two hospitals within the defined period. The total number of subjects recruited from the 2 two centres was 84. Only nurses that had a repeat CXR were included in this study. 6/84 (7%) of the CXR that were initially reported as normal were subsequently reported as abnormal and were later diagnosed as Latent TB. 2/84(2%) of the CXR that were reported as abnormal were subsequently reported as normal. The data collected in this study has demonstrated that there was a significant difference in the CXR report from overseas and the CXR report in Ireland.
