Abstract

With the increasing ease of travel and the passage of peoples between counkies there is a need to ensure that the recipient country is not burdened by the need for care of ilniiiigrant with health problems as well as the increased risk posed to the local population froni exposure to conun~unicabled isease. To assess the chest radiographs of a selected group of inun~igrantsto ascertain the presence of abnormalities especially the presence of tuberculosis. A total of 250 imniigrants were prospectively evaluated by a PA chest radiograph. The chest radiograph was evaluated by two radiologists for the presence of abnormalities of the heart, lungs, mediastinum and bony rib cage. There were 112 Indonesians, 133 Bangladeshis, one Myanmar, three Pakistanis and one others. Males made-up 222 while there were 28 females. The chest radiograph was diagnostic in all cases. There were 13 cases with enlarged hearts but with no evidence of heart failure. There was only a single inlmigrant who had evidence of active TB though there were 6 others who had evidence of old disease. There was evidence of other infections in five. With regard to the mediastinuni there was a single case with enlarged hila probably secondary to increased cardiac output. There were 21 patients with scoliosis of the spine and two with abnormaIities of the ribs. Even though there was a single case with evidence of TB from this pilot study, from unreported data from the UMMC, there were 15,16 and 23 immigrants treated for TB for 1994,1995 and 1996 respectively. This was mainly seen in the Indonesians followed by the Bangladeshis and Myanmar. We attribute this discrepancy to the biased salnpie in this study where probably only the healthy were seen while those who were not well did not want to participate in this study. In addition, this may also be due to the small sample used in this study. We feel that screening of the immigrants out in the field may be able to detect cases of active TB. As for the large hearts we feel that in the absence of any cardiac symptoms and other radiological changes these are probably due to the increased workload on the heart from physical activities. This is a recognised presentation. The changes in the mediastinum and bony rib cage are probably not very significant.
