[Would a crash helmet have been life-saving? An analysis of 188 fatal motor scooter accidents (author's transl)].

In both Germany and Denmark bills have been passed, that mopedists and motorcyclists should wear crash helmets in traffic. In an effort to elucidate the practical life-saving effect of such measures, this investigation has been performed in The Institute of Forensic Medicine, University of Aarhus, Denmark. Within the period 1959-1973 in all 188 mopedists killed in traffic accidents were submitted to medico-legal examination at the institute. All documents, including the police reports, photographs, the detailed autopsy-reports and medical case records were scrutinized in order to elucidate whether a crash helmet had been used during the accident, and if not, whether such use would have been life-saving. In 4 cases only, a crash helmet was used. Of the 188 moped drivers 54.2% died of scull-brain injuries, 33% of other injuries, while 12.8% died of combined scull-brain and other injuries. Following a thorough consideration of the circumstances and findings in each case, the authors in a retrospective judgment concluded, that 51% of the killed moped drivers probably should have survived the accident if they had worn an appropriate crash helmet. A further 8.5% might have survived. The authors admit that their material was selected and the results could hardly be considered indicative for the traffic in general, but are indicative of a tendency.

The comparability of suicide rates.

Programmes of suicide prevention require for their planning accurate epidemiological surveys. Doubt has been cast on the accuracy of many existing surveys because of the realization that suicide is under-reported and because of the lack of consistency in the procedure for suicide ascertainment. Two studies are described in this paper which attempt to examine the problem. The first is part of an international study supported by the World Health Organization. In it, Denmark and England are compared, and it is shown that there are striking differences in suicide ascertainment procedure between the two countries. Next, on a blind basis, coroners and their opposite numbers in Denmark examine a sample of each other's case records. It is found that the Danes consistently report more suicides than do the English coroners on the same case material; thus considerable doubt is cast on the supposed difference in suicide rates between the two countries. In the second study, deaths by poisoning are examined for certain coroners' districts in England and Wales. It is shown that there is considerable variation from one district to another in the relative proportions of these deaths which achieve an accident, an open or a suicide verdict. This suggests that in England and Wales coroners may not be consistent in their suicide ascertainment criteria. Hypotheses attempting to account for differences in suicide rate based on such epidemiological surveys should be viewed with great caution.

Deaths among narcotic addicts in Denmark in 1978 and 1979.

Since 1968 the number of deaths registered among narcotic addicts has increased considerably from 9 deaths in 1968 to 121 in 1979. Data concerning 215 deaths among narcotic addicts in 1978 and 1979 examined at the three Danish University Institutes of Forensic Medicine are presented. Four-fifths of the cases were males; the average age in both males and females was 26 years. In most cases a mixed abuse was present, the predominant drug being heroin. In 27% of the cases there was an abuse of alcohol. The material was divided into two groups. Group A included 181 cases in which the cause of death was poisoning by one or more drugs. In group B (34 cases) narcomania was a contributory factor to death. The place of death, gross autopsy findings and toxicological data are reported. The manner of death was in 62% of the cases stated as accident, in 19% as suicide, in 14% as accident?/suicide?, in 3% as natural death and finally in 1% as homicide. Next to traffic accidents narcotic addiction today is the greatest single cause of death in the age group 18 - 35 years. These facts call for active political steps against narcotic addiction.
