Cadmium exposure in Denmark. Based on analyses of liver and kidney tissues.

To determine the cadmium exposure level in the Danish population, tissue samples of kidney and liver were collected over the period 1981 to 1987 at the Institutes of Forensic Medicine in Copenhagen, Odense and Aarhus. A total of 795 samples were collected, of which 143 were selected for analysis using, the criteria sudden violent death (accident, homicide or suicide). Cadmium concentrations in kidney cortex increased by age to a maximum of approximately 22 micrograms/g/g (w/w) in the age group 45-55 years and decreased in the older age group, while liver concentrations tended to increase throughout the entire lifespan. Cadmium concentrations in kidney cortex and liver were found significantly correlated. The findings are in good agreement with internationally published data, but lower than previously reported Danish concentration levels. The reason for this difference is discussed.

Fatal dextropropoxyphene poisonings in Jutland, Denmark.

For many years dextropropoxyphene (dxp) has been the medicament most frequently occurring in drug poisoning cases examined at the Institute of Forensic Medicine, University of Aarhus. This study includes 85 cases of acute fatal poisoning examined in the period 1985-1987 in which dxp alone (40 cases) or in combination with alcohol (29 cases) and/or other drugs (16 cases) contributed significantly to death. Two-thirds of the deceased were men and one-third women. The average age was 37 years for both sexes. More than half of the deceased were drug and/or alcohol misusers. Eighteen were drug addicts. Half of the deaths resulted from accidents, while 40% were suicides. Accidental deaths prevailed among younger men. In a majority of the cases the drug had been taken orally. In these cases the median total blood concentration of dxp and the metabolite nordextropropoxyphene (ndxp) was 17 mg/kg in the suicide cases and 7.1 mg/kg in the accident cases. The corresponding figures for dxp without metabolite were 9.4 mg/kg and 2.2 mg/kg, respectively. The median value of the quotient dxp/ndxp was 1.9 in the suicide cases and 0.5 in the accident cases. The quotient, together with the concentrations of the drug, may therefore indicate the manner of death in many cases.

Alcohol involvement in violence. A study from a Danish community.

All cases of assaults with violence (n = 1639) from a well defined area were registered for 1 year. A positive alcolmeter test (% greater than 0.2) was registered in 488 cases (29%). A further 216 patients (13%) were found under the influence of alcohol according to a simple clinical judgement. In nine of ten manslaughter and murder cases alcohol was involved. Young men, 19-29 years of age, comprised the majority of victims. Of the episodes of violence 66% took place during the weekend. In 250 cases the alcohol concentration surpassed 1.5%. Almost 50% of the violence episoded took place in or around restaurants. Blunt violence was concerned in 73% of the episodes. Gunshot was registered in five cases, stabbings in two cases.

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.

Liver histology in a 'normal' population--examinations of 503 consecutive fatal traffic casualties.

The liver histology of 503 consecutive victims of fatal (within 24 hours) traffic accidents submitted to medico-legal autopsy are used as a standard of reference. In 370 persons (74%) no pathological changes in the liver biopsies were observed. Fatty liver was found in 120 persons (24%), non-specific portal inflammation in 7 persons, alcoholic hepatitis in 6, and portal fibrosis in 5. No cases of cirrhosis, chronic aggressive hepatitis, changes compatible with chronic persistent hepatitis, viral hepatitis, or other internationally accepted morphological diagnoses were found. A significant positive correlation between the frequency of steatosis and age groups was demonstrable. Fatty liver was found in 1% of persons below 20 years, in 18% between 20--40 years, and in 39% of persons more than 60 years in this normal material. The persons with fatty liver had a higher body weight, but the overweight was not correlated to age. It is concluded that fatty infiltration in the liver is a normal observation in aged persons.
