title: Tuberculosis in Auckland autopsies, revisited.
abstract: OBJECTIVE
  To review the cases of tuberculosis found at autopsy in the Auckland Coronial Autopsy Service in the previous 10 years, and compare the results with that of a similar study for the period 1975 to 1992. Cases which were not diagnosed prior to autopsy are scrutinised as to why the diagnosis may have been missed.
  
  
  METHODS
  A computerised search of the Forensic Pathology Department database at Auckland Hospital for cases of tuberculosis or atypical mycobacterial infection found at autopsy was done. Basic demographic data, past medical history, and police reports were analysed. The cases were placed into five groups for analysis.
  
  
  RESULTS
  A total of 30 cases of tuberculosis (including 3 cases of atypical mycobacterial infection) were found. A large proportion (70%) was undiagnosed before death, and each case was potentially infective. Two cases had respiratory symptoms suggestive of tuberculosis, and a further 5 cases had generalised symptoms which were unexplained yet tuberculosis was not considered.
  
  
  CONCLUSIONS
  In those cases that were missed, the autopsy played a vital role by identifying the previously undiagnosed cases of tuberculosis and ensuring contact screening. Awareness of tuberculosis and its increasing prevalence in New Zealand is essential for minimising missed diagnoses.
