RESUMO
Ambient air quality is a major issue today in large cities all over the world. On the theoretical background of the health belief model and the health locus of control model, we studied the knowledge and beliefs about air pollution and the modifications of health behaviour brought about by information to the public about projected levels of air pollution, with special emphasis on reduction of outdoor activity and avoidance of car driving. Data were collected with a questionnaire among a sample of residents in the Copenhagen area. The respondents were almost universally knowledgeable about the prime emission source and concerned about the possible health effects of the air pollution in the area. Avoidance of outdoor activity was associated with personal experiences of symptoms ascribed to the air pollution, employment status, and with female sex, but not with knowledge or beliefs about the degree or health implications of the air pollution. The willingness to avoid car driving was positively associated with the belief that one can oneself influence one's health and with female sex. Lung diseased respondents were generally more prone to protect themselves than the healthy, both by avoiding outdoor activity and by being less willing to avoid car driving. The present study was conducted in an only moderately polluted city, and it is not clear whether the findings and conclusions can be generalized to more polluted cities. The study partly supported the underlying theories of the determinants of health behaviour, but also indicated a need for a broader theoretical framework, incorporating aspects of the respondents' life situation and personal experience which would be relevant to the specific type of health behaviour under study.

The Gram-negative rod DF-2 was isolated from blood-cultures, the blood sample taken 3 days after death from a 65-year-old woman who had been bitten in her finger by her dog. At the medico-legal external examination marbling of the skin was found, suggesting septicemia. In persons found dead with a history of dog exposition and with no other obvious cause of death, examination for DF-2 should be performed.

In the period 1988-1991 the HIV-1 antibody test was performed in a total of 389 autopsied drug addicts. The HIV-1 incidence rose from 6% in 1988 to 14% in 1990 and 14% in 1991. There was no significant difference between the cumulated incidence in males and females. The HIV-1-positive addicts were compared to the HIV-1 negative addicts as regards mean age, duration of abuse, residence and cause and manner of death. Except for residence, where significantly more HIV-1-positive than negative addicts lived in Copenhagen, there were no significant differences between the two groups. In about one-third of the HIV-1-positive cases, equal both for males and females, the HIV-1-positivity was not known beforehand. The results are discussed in relation to the findings in other countries and to the findings in selected groups of living addicts in Copenhagen. It is concluded, that the diagnosis of HIV-1 infection in autopsied drug addicts is important from epidemiologic and hygienic points of view.

In 1987 a total of 89 intravenous drug addicts were admitted to medico-legal autopsy at the University Institute of Forensic Medicine in Copenhagen. Totally 10 cases were reactive by the Elisa test and five of these, or 7% of the total material tested, could be confirmed by the immuno-blotting test. The other five cases must be considered as false positive, possibly due to antibodies against cellular antigens. Among the five real positive cases, four were known before-hand while in one case the HIV-positivity was not known. These findings - together with the possibility of false negative reactions - especially regarding persons with acute HIV-infection, requires special precautionary measures when autopsies of drug addicts are performed.

A 59-year-old woman who intentionally ingested 100-200 ml Basagran was taken to the hospital with a cardiac arrest 2 days after she had consumed the herbicide. During this period she suffered vomiting, urination and diarrhoea and she was drowsy with a muddled speech. Biological samples obtained at the autopsy were analysed and presence of bentazone, alcohol and an active metabolite of citalopram were detected. Blood concentrations of bentazone, alcohol and desmethyl-citalopram were 625 mg/kg, 0.62 g/l and 0.03 mg/kg, respectively.

Forensic pathologists are familiar with alcohol abusers, who are found dead and in whom the cause of death cannot be ascertained. In order to examine the possible role of ketoacidosis for the cause of death in this group of alcohol abusers, the concentrations of ketone bodies (acetone, acetoacetate, D-beta-hydroxybutyrate) were determined in post mortem blood specimens. Determination of the ketone body concentrations were made by a coupled enzymatic head-space gas chromatographic method. The material consisted of blood specimens from 131 deceased persons and was divided into three groups: Group 1: controls, 79 cases of non alcohol abusers; group 2: 35 cases of alcohol abusers with known causes of death and group 3: 17 cases of alcohol abusers without ascertainable cause of death. The geometric means for the sum of the ketone body concentrations in blood were: controls, 109 mumol/l; alcohol abusers with known causes of death, 152 mumol/l; and alcohol abusers without known cause of death, 590 mumol/l. The limit value between the controls and the group of alcoholics with unascertainable cause of death was by logistic regression found to be 531 mumol/l (343-1224 mumol/l). The term 'ketoalcoholic death' is, therefore, suggested, when the measured post mortem blood ketone body concentration in an alcoholic with otherwise unknown cause of death exceeds 531 mumol/l.

Experiments were conducted to investigate the concentration of carbon monoxide (CO) in a car cabin under suicide attempts with different vehicles and different start situations, and a mathematical model describing the concentration of CO in the cabin was constructed. Three cars were set up to donate the exhaust. The first vehicle didn't have any catalyst, the second one was equipped with a malfunctioning three-way catalyst, and the third car was equipped with a well-functioning three-way catalyst. The three different starting situations were cold, tepid and warm engine start, respectively. Measurements of the CO concentrations were made in both the cabin and in the exhaust pipe. Lethal concentrations were measured in the cabin using all three vehicles as the donor car, including the vehicle with the well-functioning catalyst. The model results in most cases gave a good prediction of the CO concentration in the cabin. Four case studies of cars used for suicides were described. In each case measurements of CO were made in both the cabin and the exhaust under different starting conditions, and the mathematical model was tested on these cases. In most cases the model predictions were good.

Air and water powered tools are employed increasingly in industry and involve new possibilities for occupational casualties. A new mechanism of trauma is described where the cause of death was an injury to the head, similar to a firearm wound. The "missile" was the water beam from the victim's own high pressure cleansing device, which was able to produce water pressure up to 900 atmospheres resulting in high water velocity of 300 meters/second. As prophylaxis, new legislations, as a result of understandings between employers and employees in the member states of the Common Market, are under preparation at present.

A case of sudden unexpected death after an insect sting in a middle aged man known to be allergic to insect stings is presented. In connection with an allergic shock, many years before death occurred, he had been offered allergological investigation. If the directives in the consensus report on insect sting allergy, recently published by the Danish Association for Allergology had been followed, similar deaths and expensive visits to casualty departments could probably be reduced.

A case of maternal death and still birth in the 35th week of pregnancy is described where the cause of death was the very rarely diagnosed phlegmonous gastritis. The phlegmonous gastritis is characterised by dangerous, fulminating pyogenic bacterial infection of the gastric wall with alpha-haemolytical streptococci. The entity seems to have been well-known earlier, but has only been reported sparsely in contemporary medical literature. It cannot be ruled out that the disease may have been misdiagnosed on several occasions in recent decades because of symptomatic treatment. In presenting the case, the authors seek to attract attention to this disease--that according to the contemporary medical literature seems mostly to be induced by modern treatment with antacids and after gastroscopy--because it can be effectively treated with modern antibiotics, possibly in combination with gastrectomy.

BACKGROUND: Trauma death has traditionally been described as primarily occurring in young men exposed to penetrating trauma or road traffic accidents. The epidemiology of trauma fatalities in Europe may change as a result of the increasing proportion of elderly patients. The goal of this study was to describe age-related differences in trauma type, mechanism, cause and location of death in a well-defined European region. METHODS: We prospectively registered all trauma patients and severe burn patients in eastern Denmark over 12 consecutive months. We analyzed all trauma fatalities in our region regarding the trauma type, mechanism, cause and location of death. RESULTS: A total of 2,923 patients were registered, of which 292 (9.9%) died within 30 days. Mortality increased with age, with a mortality of 46.1% in patients older than 80 years old. Blunt trauma was the most frequent trauma type at all ages, but the trauma mechanism differed among ages, with falls constituting 46.8% of trauma deaths in the elderly. The primary cause of death was head and spine injuries across all age-groups. Death took place before arrival at the hospital in 45% of the cases, but death during primary admission became increasingly important with advanced age. CONCLUSION: Increasing age was associated with higher mortality, an increased proportion of falls and fatal head or spine injuries.
