title: [Clinical analysis on tuberculosis cases among foreigners in our hospital].
abstract: BACKGROUND
  Although the incidence rate in Japan has been decreasing since the declaration of tuberculosis emergency in 1999, the reported tuberculosis cases among foreigners have been increasing year by year (from 5.1% in 2000 to 6% in 2003). As the number of foreign residents in Japan has been increasing every year, tuberculosis cases among them are also expected to increase.
  
  
  OBJECTIVE
  The aim of this study is to investigate and clarify clinical features of recent tuberculosis patients among foreigners.
  
  
  OBJECTIVE
  Fifty-two cases were analyzed, who were admitted to our hospital because of active tuberculosis from January 2004 to April 2007.
  
  
  RESULTS
  Among total 52 cases, male was 29, female 23, and the mean age (SD) of the patients was 31.8 (+/- 8.8) years old. Their mother countries were China, Republic of Korea and so on. The cavitary lesions were found on chest X-ray in 54%, the drug resistant rate was 8.2%, and the treatment completion rate was 92%.
  
  
  CONCLUSIONS
  Comparing with reports in the past, almost parameters about tuberculosis control have improved, for example the drug resistant rate was decreased and the treatment completion rate was increased. The promotion of DOTS strategy in Japan might be attributed to the improvement of these parameters. Because more immigrants from the developing countries are expected in near future, not only strengthening current DOTS strategy but also new countermeasures such as QFT-2G and Electronic-Nose Technology should be introduced into tuberculosis control of foreigners living in Japan to decrease tuberculosis incidence and improve treatment outcome by early detection and adherence to treatment.
