title: Pathoanatomic findings and blood alcohol analysis at autopsy (BAC) in forensic diagnoses of undetermined suicide. A cross-cultural study.
abstract: In Sweden, ca. 25% of unnatural deaths ascribed to self-inflicted injury are finally recorded as 'undetermined suicide' (abbreviated UMSA), i.e. the forensic pathologist has not been able to establish whether the fatality was an accident or a suicide. In the present study, a series of UMSA cases was investigated with the aims to study the impact of immigrant status, and alcohol abuse on the occurrence of this forensic diagnosis on the mode of death. The alcohol issue was addressed by focusing on blood alcohol concentrations at autopsy (BAC) and post mortem signs of alcohol-related organ pathology. The results can be summarised as follows: Positive BAC occurred at an equal rate in the UMSA group and in definite suicides, i.e. about 45%. Among non-Swedish UMSA victims positive BAC was more common (50%) than among the Swedish (41%), whereas no difference was found in the definite suicide group. The level of BAC at autopsy was significantly higher in Finnish immigrants than in other ethnic groups. Organic signs of chronic alcohol abuse were found in 13 of 40 cases testing positive for BAC; thus, presence of alcohol at autopsy may reflect incidental intake rather than habitual overconsumption.
