Comparison of blood-ethanol concentration in deaths attributed to acute alcohol poisoning and chronic alcoholism

Ethanol concentrations were measured in femoral venous blood in deaths attributed to acute alcohol poisoning (N = 693) or chronic alcoholism (N = 825), according to the forensic pathology report. Among acute alcohol poisonings were 529 men (76%) with mean age 53 years and 164 women (24%) with mean age 53 years. In the chronic alcoholism deaths were 705 men (85%) with mean age 55 years and 120 women (15%) with mean age 57 years. The blood-ethanol concentrations were not related to the person's age (r = -0.17 in acute poisonings and r = -0.09 in chronic alcoholism). The distribution of blood-ethanol concentrations in acute poisoning cases agreed with a normal or Gaussian curve with mean, median, standard deviation, coefficient of variation, and spread of 0.36 g/100 mL, 0.36 g/100 mL, 0.086 g/100 mL, 24% and 0.074 to 0.68 g/100 mL, respectively. The corresponding concentrations of ethanol in chronic alcoholism deaths were not normally distributed and showed a mode between 0.01 and 0.05 g/100 mL and mean, median, and spread of 0.172 g/100 mL, 0.150 g/100 mL, and 0.01 to 0.56 g/100 mL, respectively. The 5th and 95th percentiles for blood-ethanol concentration in acute poisoning deaths were 0.22 and 0.50 g/100 mL, respectively. However, these values are probably conservative estimates of the highest blood-ethanol concentrations before death owing to metabolism of ethanol until the time of death. In 98 chronic alcoholism deaths (12%) there was an elevated concentration of acetone in the blood (>0.01 g/100 mL), and 50 of these (6%) also had elevated isopropanol (>0.01 g/100 mL). This compares with 28 cases (4%) with elevated blood-acetone in the acute poisoning deaths and 22 (3%) with elevated blood-isopropanol. We offer various explanations for the differences in blood-ethanol and blood-acetone in acute poisoning and alcoholism deaths such as chronic tolerance, alcohol-related organ and tissue damage (cirrhosis, pancreatitis), positional asphyxia or suffocation by inhalation of vomit, exposure to cold coupled with alcohol-induced hypothermia, as well as various metabolic disturbances such as hypoglycemia and ketoacidosis.     

Urine/blood ratios of ethanol in deaths attributed to acute alcohol poisoning and chronic alcoholism

The concentrations of ethanol were determined in femoral venous blood (BAC) and urine (UAC) and the UAC/BAC ratios were evaluated for a large case series of forensic autopsies in which the primary cause of death was either acute alcohol poisoning (N=628) or chronic alcoholism (N=647). In alcohol poisoning deaths both UAC and BAC were higher by about 2g/l compared with chronic alcoholism deaths. In acute alcohol poisoning deaths the minimum BAC was 0.74 g/l and the distribution of UAC/BAC ratios agreed well with the shape of a Gaussian curve with mean+/-standard deviation (S.D.) and median (2.5th and 97.5th centiles) of 1.18+/-0.182 and 1.18 (0.87 and 1.53), respectively. In alcoholism deaths, when the BAC was above 0.74 g/l (N=457) the mean+/-S.D. and median (2.5th and 97.5th centiles) UAC/BAC ratios were 1.30+/-0.29 and 1.26 (0.87 and 2.1), respectively. When the BAC was below 0.74 g/l (N=190), the mean and median UAC/BAC ratios were considerably higher, being 2.24 and 1.58, respectively. BAC and UAC were highly correlated in acute alcohol poisoning deaths (r=0.84, residual S.D.=0.47 g/l) and in chronic alcoholism deaths (r=0.95, residual S.D.=0.41 g/l). For both causes of death (N=1275), the correlation between BAC and UAC was r=0.95 and the residual S.D. was 0.46 g/l. The lower UAC/BAC ratio observed in acute alcohol poisoning deaths (mean and median 1.18:1) suggests that these individuals died before absorption and distribution of ethanol in all body fluids were complete. The higher UAC/BAC ratio in chronic alcoholism (median 1.30:1) is closer to the value expected for complete absorption and distribution of ethanol in all body fluids.     

A field experiment on ethnic discrimination among local Swedish public officials

This study presents an innovative field experiment exploring ethnic discrimination in contacts between local public officials and members of Swedish society. Using a correspondence study design, fictitious individuals with Arabic- and Swedish-sounding names contacted Swedish municipalities via email, asking questions about access to preschools. The findings indicate disadvantageous treatment of individuals with Arabic-sounding names in terms of the informal tone of the replies, as Swedish-sounding names were replied to in a friendlier, more welcoming way. Regarding the more formal aspects of the emails – i.e., whether they were replied to at all and the questions posed were directly answered – no statistically significant signs of discrimination emerge (although differences were of some substantial size, to the disadvantage of Arabic-sounding names). Still, informal disadvantageous treatment is sufficient cause for concern and noteworthy in the case of Sweden, considering its reputation as being egalitarian, immigration friendly and democratically well functioning.     

Public sector efficiency: the roles of political and budgetary institutions, fiscal capacity, and democratic participation

The purpose of this paper is to investigate whether efficiency in public service provision is affected by political and budgetary institutions, fiscal capacity, and democratic participation. In order to address this issue we take advantage of a new global efficiency measure for Norwegian local governments. We find that high fiscal capacity and a high degree of party fragmentation contribute to low efficiency. In addition there is some evidence that democratic participation increases efficiency, while a centralized top-down budgetary procedure is associated with low efficiency.     

Legislative Organization and Pollution Taxation

The role of political institutions in shaping public policy has been analyzed in isolation from corruption, and legislative organization (specifically, bicameralism) has received minimal attention. We analyze pollution taxation when decisions are influenced by several veto players, such as legislative chambers. Our theory predicts that an increase in the number of veto players (e.g., moving from uni- to bi-cameralism) pushes the pollution tax towards the social optimum, with the effect being conditional on corruption. As such, dispersion around the optimal tax is lower under bicameralism. Empirical tests – using data from 86 countries – support the theory.     

Liver pathology in fatal drug addiction

Liver sections from 273 drug addicts submitted to medicolegal autopsy at the Institute of Forensic Medicine in Copenhagen in the period 1975 – 1979 were studied. In 65% of the cases non-specific portal inflammation only was found. Birefringent foreign material — identified as the mineral talc (magnesium silicate) was observed in 38% of the cases; in these cases non-specific portal inflammation was always present. Changes compatible with acute or chronic persistent hepatitis or hepatitis sequelae were observed in 8% of the cases; cirrhosis in 3%. HBs-antigen was detected in 4%. In 22% fatty infiltration was present; in 4% as the only abnormal finding. Finally no pathological changes were found in 6%. The results were related to anamnestic information of kind and duration of drug abuse and to the cause of death. Furthermore a comparison was performed between the groups with and without birefringent material. The data suggest that the birefringent material may be of importance to the pathogenesis of the non-specific portal inflammation.     

Abnormally high concentrations of amphetamine in blood of impaired drivers

We present a case series (N = 46) of individuals apprehended in Sweden for driving under the influence of drugs (DUID). These cases were selected because the concentrations of amphetamine in blood were abnormally high (> 5.0 mg/L), the highest being 17 mg/L. In comparison, the median blood-amphetamine concentration in a population of DUID offenders (N = 6,613) was 0.70 mg/L. Among the DUID suspects with extremely high blood-amphetamine concentrations there were 38 men (83%) with mean age of 37.8 y (SD 6.8 y) and 8 women (17%) with a mean age of 34.1 y (SD 4.3 y). All had previously been registered in our database (mean 12 times, median 9 times) for drug-related offences, including DUID. The concentration of amphetamine in blood of female offenders was slightly higher than the concentration in male offenders (6.6 mg/L vs. 5.8 mg/L), although this difference was not statistically significant (p > 0.05). The drugs other than amphetamine most frequently encountered in the blood samples were tetrahydrocannabinol and benzodiazepines (diazepam and nordiazepam). The commonest signs of drug use reported by the arresting police officers were bloodshot and glazed (watery) eyes, restlessness, talkativeness, exaggerated reflexes and slurred speech. Unsteady gait and dilated pupils were observed in some but not all individuals. These very high concentrations of amphetamine were tolerated without any fatalities indicating a pronounced adaptation to the pharmacologic effects of this central stimulant. Anecdotal information indicated that those with the very highest concentrations of amphetamine in blood had swallowed the drug to prevent being apprehended in possession of an illicit substance.     

Alcohol and drugs in drivers fatally injured in traffic accidents in Sweden during the years 2000-2002

During the years 2000-2002, alcohol, pharmaceuticals and illicit drugs were analysed in blood samples from fatally injured drivers in Sweden. The total number of drivers was 920 and in 855 of these, corresponding to 93%, a toxicological investigation was performed. About 85% of the drivers were men and 15% were women. All but three women (96%) were car drivers while the corresponding figure for men was about 78% and about 13% were motorcyclists. The number of positive cases increased from 38.9% in year 2000 to 45.9% in year 2002 and alcohol was the most common drug with frequencies of 19.8%, 25.0% and 21.8% for the studied years 2000, 2001 and 2002, respectively. The median blood alcohol concentration ranged from 1.6 to 2.0mg/mL for men and from 1.2 to 1.8 mg/mL for women. There was a decrease in cases where alcohol was the only drug detected, from 52 out of 58 cases (90%) in year 2000 to 41 out of 61 cases (67%) in 2002. At the same time there was an increase, from 5.4% to 10.0% of illicit drugs, mainly amphetamine, and the cases with multiple drug intake increased from 10% to 26%. The prevalence of pharmaceuticals as the only drug or drugs detected decreased from 14.0% to 10.4% and in the majority of these cases the drug concentrations were within the therapeutic range.     

Flunitrazepam: an evaluation of use, abuse and toxicity.

The benzodiazepine flunitrazepam is extensively prescribed to patients with insomnia in many countries, but has also become popular among alcohol- and drug abusers. Several reports indicate that it is used as a date rape drug and suggest that it may precipitate violent behavior. Furthermore, flunitrazepam is involved in many fatal intoxications in Sweden. This study was designed and conducted to explore the negative consequences of flunitrazepam abuse in Sweden, and to assess the trends in its use and abuse. The occurrence of flunitrazepam in cases referred to the Department of Forensic Chemistry in Link?ping, Sweden 1992-1998, was investigated in detail. The detections were studied separately for different groups; medicolegal death investigations, drug abuse cases, driving under influence cases, and other medicolegal cases. These data were further compared with the sales, and seizures by the Swedish Customs and the Swedish Police. During 1992-1998, 641 fatalities occurred, where the cause of death was attributed to intoxication with flunitrazepam solely (130) or in combination with other drugs, or concomitant conditions (511). In 78% of all driving under influence cases, where flunitrazepam was detected, the analyses also disclosed the presence of illicit drugs. A similar association was seen in drug abuse cases. The seizures reported by the Swedish Customs revealed a substantial and increasing illegal trade. Cases, where flunitrazepam seemingly induced violent behavior were identified, and one of these is described in some detail. It is concluded that the abuse pattern and the toxicity of flunitrazepam should be kept in mind by forensic investigators and that this panorama also should be considered when decisions about the registration and classification of flunitrazepam are made in different countries.
