Water traffic accidents, drowning and alcohol in Finland, 1969-1995.

OBJECTIVE: To examine age- and sex-specific mortality rates and trends in water traffic accidents (WTA), and their association with alcohol, in Finland. MATERIALS AND METHODS: National mortality and population data from Finland, 1969-1995, are used to analyse rates and trends. The mortality rates are calculated on the basis of population, per 100000 inhabitants in each age group (<1, 1-4, 5-14, 15-24, 25-44, 45-64, > or = 65), and analysed by sex and age. The Poisson regression model and chi2 test for trend (EGRET and StatXact softwares) are used to analyse time trends. RESULTS: From 1969 through 1995 there were 3473 (2.7/100000/year; M:F= 20.4:1) WTA-related deaths among Finns of all ages. In 94.7% of the cases the cause of death was drowning. Alcohol intoxication was a contributing cause of death in 63.0% of the fatalities. During the study period the overall WTA mortality rates declined significantly (-4% per year; P < 0.001). This decline was observed in all age groups except > or = 65 year olds. The overall mortality rates in WTA associated with alcohol intoxication (1987-1995) also declined significantly (-6%; P = 0.01). CONCLUSIONS: In Finland, mortality rates in WTA are exceptionally high. Despite a marked decline in most age groups, the high mortality in WTA nevertheless remains a preventable cause of death. Preventive countermeasures targeted specifically to adult males, to the reduction of alcohol consumption in aquatic settings and to the use of personal safety devices should receive priority.

Changes in neurons and interneural connections of the higher sections of the motor system in the progeny of alcoholized male and female rats.

We have studied the effects of long-term alcoholic intoxication of male and female rats on the structural development of the sensory motor cortex and the caudate nucleus in 21-day-old rats (their progeny). Using light microscopy and morphometry we observed a delay in the maturation of neurons and their dendrites, and also dystrophic changes in the nerve structures in the experimental animals. The morphological changes observed show that alcoholic intoxication of parents leads to negative effects on postnatal development of their progeny.

[Effect of the composition of branched chain amino acids, taurine, and tryptophan on the amino acid metabolism in experimental models of alcoholism].

Ethanol withdrawal after forced alcoholization of rats according to Majchrowicz led to the development of amino acid imbalance in the pool of free amino acids in the liver (increasing levels of alanine, aspartate, glutamate, glutamine and histidine, decreasing levels of glycine, lysine, threonine and taurine) and blood plasma (increasing levels of tyrosine and alanine, decreasing levels of most glycogen aminoacids, branched-chain aminoacids and Lys). Less profound changes were observed after prolonged alcohol intoxication (decreasing levels of alanine, ornitine, citrulline and increasing level of Glu in liver, increasing levels of sulfur-containing compounds, Asp and Lys in blood plasma). Amino acid mixture which contained branched-chain amino acids, taurine and tryptophan administered intragastrically was found to correct levels of sulfur-containing amino acids, threonine, lysine and isoleucine after ethanol withdrawal and to eliminate disorders in urea cycle, exchange of threonine, glycine and phenylalanine after prolonged alcohol intoxication.

Acute, withdrawal, and chronic alcohol effects in man: event-related potential and quantitative EEG techniques.

The results presented here strongly suggest that quantitative electroencephalography and event-related potentials are excellent research tools and may be clinically useful as non-invasive monitors of psychotropic drug action and encephalopathies. Our initial data with acute mild alcohol intoxication show that acute tolerance may be reflected in qEEG but not in P3 latency. Since predictably some brain functions may show tolerance, and others not, these approaches may be useful probes. The amplitude of N1-P2 appears to differentiate alcoholics with and without a history of withdrawal seizures. This technique may thus prove useful in determining treatment and monitoring treatment effects in alcohol withdrawal. P3 latency appears to be normal in Korsakoff's syndrome, unlike in Alzheimer's disease. The combination of the event-related potentials with neuropsychology and magnetic resonance imaging scans should be invaluable for future research in these patient groups. Many patients with severe liver disease superficially appear mentally intact. The event-related potential and quantitative electroencephalography findings we have demonstrated may indicate those at greater risk for alterations in brain functioning. These techniques may also prove useful in diagnosing other "subclinical" encephalopathies and further our understanding of the underlying brain pathophysiology.

Women and alcohol: use and abuse.

National surveys of the quantity/frequency of drinking, conducted over the last half century, show that the percentage of nonabstaining women has remained at about 60%. Although male/female differences in drinking are smaller than they were a generation ago, this appears to relate primarily to drinking by young adults. Study of social attitudes toward male and female intoxication has consistently indicated more disapproval of female intoxication. Alcoholism in women has a complex etiology that includes biological factors, positive family history, difficulties in impulse control, depression, and drinking by significant others in the social environment. Male/female differences in patterns and consequences of alcoholic behavior are summarized, as are differences among alcoholic women with earlier or later onset.

Morphological changes in genesial system of men: medico-legal aspects.

With the purpose of perfection of examination the character of structural changes in testicles and prostate is investigated; the comparative qualitative and quantitative analysis of cellular reactions of persons with chronic somatopathies (rheumatic disease, idiopathic hypertensia) and chronic household intoxications (alcoholic illness, narcomania) is carried out. The work is carried out on 50 corpses of male persons, 18-35 years old, who died of chronic drunkenness (13 observations), narcomania (20), idiopathic hypertensia (9), and rheumatic disease (8). The suppression of testicles was characterized by disturbances of spermatogenesis at a level of the cell population, characteristic for a zero and first degree of spermatogenesis activity especially expressed in chronic narcotic intoxication. The damage to a prostate was stacked in a picture of a chronic relapsing prostatitis and chronic indurative prostatitis with the outcome of cirrhosis of prostata, being most typical for chronic alcohol intoxication. Morpho-functional investigation of a prostate and testicles affected by chronic somatopathies and chronic household intoxications, both qualitative and quantitative, testify to reduction of function of activity of these organs (hormonal imbalances, mail sterility, sex frustration). Thus, the persons suspected of violent actions of a sexual nature should be examined in order to reveal both erectile dysfunctions and disruption of spermatogenesis.

[Suicidal behavior as a socio-hygienic problem].

An assessment of changes in the incidence of suicides is provided. An analysis is made of age- and sex-related features, motivation, methods, the level of alcohol intoxication at the moment of autoaggression; the extent of impact is determined which suicide and autoaggression make on the main economic-demographic indices. It has been found that the established level of suicidal actions incidence influences the main economical and demographic indices. Positive changes occurring recently in the life of society, the realization of measures to combat hard drinking and alcoholism resulted in the reduction of suicide incidence. However, despite the decrease in suicide incidence the proportion of persons among suicides who resorted to the act of autoaggression during alcohol intoxication remains practically at the same level. Suicidal behavior leading to the tragic outcome should be considered as a socio-hygienic problem as it is caused by lifestyle, insufficient social and medico-psychological protection, close association with alcohol abuse and has a considerable impact on the medico-demographic indices characterizing the state of population's health.

Diazepam prevents progression of kindled alcohol withdrawal behaviour.

The purpose of the present experiment was to study the "kindling" hypothesis of alcohol withdrawal stating that exposure to repeated episodes of alcohol withdrawal results in an increased severity of subsequent withdrawal reactions. Two groups of male Wistar rats were subjected to 13 episodes of 2 days severe alcohol intoxication and 5 days alcohol withdrawal. Animals in the control group (n = 80) developed clinical withdrawal signs following each intoxication episode. In the diazepam group (n = 80) the withdrawal reactions during episodes 1-9 were blocked by intraperitoneal diazepam administration (0-30 mg/kg) 8, 11 and 15 h into withdrawal. During episode 10-13 diazepam treatment was terminated and convulsive withdrawal behaviour was observed 9-15 h after last alcohol dose. The probability of seizure activity during these four withdrawal episodes was calculated as 0.239 and 0.066 in the control and the diazepam groups, respectively. Based on Monte Carlo simulation techniques, this difference was found to be statistically significant (P < 0.05). No differences in the non-convulsive alcohol withdrawal symptoms tremor, hyperactivity and rigidity were detected between controls and diazepam animals after diazepam treatment. It was concluded that the increased convulsive behaviour in the control group was caused by cumulated kindling-like cerebral alterations during the previous repeated alcohol withdrawal phases.

[Effects of stress on indices for assessing zinc nutrition status].

To evaluate the specificity of some functional indices in assessment of body zinc nutrition status, we used experimental rat model to observe the effects of some factors, such as forced swimming, starvation, trauma and alcohol intoxication on zinc the status. Plasma zinc levels of rats significantly decreased after trauma increased after starvation. Liver zinc content showed a rising tendency in trauma and starvation rats. Activities of superoxide dismutase in red blood cells and alkaline phosphatase, mannosidase, 5'-nucleotidase in plasma of rats with alcohol intoxication declined significantly. Starvation led to decreased activities of alkaline phosphatase and angiotensin-converting enzyme, but increased activities of mannosidase. Trauma and forced swimming could cause increase of angiotensin-converting enzyme activity and decrease of 5'-nucleotidase activity, respectively. These results indicate that physiological and pathological effects should be excluded from of the above indices as plasma zinc index, in the assessment of body zinc nutrition status.

A prospective epidemiological study on the occurrence of antiphospholipid antibody: the Montpellier Antiphospholipid (MAP) Study.

The objective of this study was to determine the prevalence and clinical significance of elevated antiphospholipid antibodies (APA) in a large series of patients admitted to a department of Internal Medicine. At the end of entry phase, 1014 patients were tested (488 males-526 females, mean age: 66.7 years, range 18-97). Seventy-two (7.1%) patients were found APA positive at least once: 44 males and 28 females, mean age 69 years, range 23 to 94. Twenty fulfilled the criteria of Primary Antiphospholipid Antibody Syndrome: 10 patients were referred for deep vein thrombosis, 3 had history of deep vein thrombosis, 1 had both arterial thrombosis and a history of venous thrombosis; 2 had thrombocytopenia; 3 had stroke, 1 had a history of a stroke. One patient had SLE according to ARA classification. The most frequent associated disease was cancer: 14 patients, 9 had evolutive malignant disease, 5 were in clinical remission of neoplasia. Other clinical conditions included chronic and/or acute alcoholic intoxication (n = 8), severe atherosclerosis (n = 4), leg ulcer (n = 4). Insufficient data are available about the evolution, but 7 patients died in the year following diagnosis. Eight patients had fluctuations in APA detection: 2 initially APA positive became negative, 5 initially negative became positive and 1 patient was alternatively positive, negative and positive without steroid treatment. Thus, as expected, APA occur in a variety of clinical disorders. The association with cancer or alcoholic intoxication deserves further investigations.

Hemodynamic effects of alcohol at rest and during upright exercise in coronary artery disease.

The hemodynamic effects of acute alcohol intoxication were studied at rest and during upright exercise in 28 patients with coronary artery disease by right-sided heart catheterization and radionuclide cardiography. The mean arterial blood pressure at rest was reduced by 5% and the left ventricular ejection fraction at rest decreased 2% because of end-systolic dilation during intoxication (serum ethanol 21 mmol/liter). No changes were observed in heart rate, stroke volume, pulmonary artery pressure, pulmonary artery wedge pressure or total peripheral resistance. No significant changes occurred in plasma catecholamines, and no changes occurred in any variable during mild exercise corresponding to a 30 to 40% heart rate increase. Thus, alcohol ingested in moderate doses causes slight impairment of left ventricular emptying and a reduction in the arterial blood pressure at rest in patients with coronary artery disease. A mild exercise load can be tolerated during alcohol intoxication without hemodynamic changes.

[Treatment of acute alcoholic alcoholism].

Acute alcoholic hepatitis is the first alcoholic lesion of the liver in the process of progression to cirrhosis. It is due to the toxic action of alcohol on hepatocytes, in particular in the centrolobular region. It may affect a liver which is the site of fatty infiltration, fibrosis or cirrhosis, i.e. during all the stages of alcoholic liver disease. Its severity depends upon the degree of alcoholic intoxication. It may be fatal by malignant hepatic failure in a quarter of cases or, at the extreme, be totally asymptomatic. The aims of treatment are: 1) in the immediate, to prevent death; 2) subsequently, to prevent progression to cirrhosis. The majority of the wide range of treatments suggested have been evaluated in controlled trials. It is thus easy to show that corticosteroids are effective in severe acute alcoholic hepatitis, i.e. with encephalopathy and coagulation disturbances, but no in ordinary forms. Although logical, nutritional supplements, whether enteral or parenteral, have no influence on the course of acute alcoholic hepatitis. The same applies to anabolic steroids, the association insulin-glucagon, antifibrosis agents or "hepatoprotectors". The elimination of alcoholic intoxication remains the most important point, accepted by all hepatologists.

Palpitations and lifestyle: impact of depression and self-rated health. The Nordland Health Study.

On the basis of a questionnaire in a population study in the county of Nordland, Norway, the prevalence of palpitations and its associations to some lifestyle factors, depression and self-rated health were analysed. All the 10,497 residents aged 40 to 42 years were invited to participate, 82% attended, 87% of the attenders returned a questionnaire by mail, and 6436 subjects were included in this report. The prevalence of palpitations was 15% in men and 25% in women. Palpitations were significantly associated with coffee consumption, smoking, alcohol intoxication, physical inactivity, depression and poor self-rated health in the univariate analyses. In a logistic regression analysis, the relations between palpitations and lifestyle were weakened. Significant predictors for palpitations were depression and poor self-rated health in both sexes, in addition to heavy coffee drinking and physical inactivity in men and alcohol intoxication in women. In conclusion, palpitations were more firmly linked to depression and self-evaluated health than to lifestyle.

Toxicological screening in trauma.

OBJECTIVES: To determine the prevalence and patterns of alcohol and drug use in patients with major trauma. METHODS: Consecutive trauma patient enrollment, 24 hours a day, was envisaged with anonymised patient data on gender, age band, and mechanism of injury collected. The study group had surplus plasma quantitatively analysed for ethanol concentration, and urine samples were initially screened, via immunoassay, for opiates, cannabinoids, amphetamines, benzodiazepines, cocaine, and methadone. Confirmation and specification of individual positive results was then performed using thin layer or gas-liquid chromatography. Drugs of treatment given in the resuscitation room, if subsequently detected in the urine samples, were excluded from the final results. RESULTS: There were 116 eligible trauma patients assessed and treated in the resuscitation room over a six month period, of which 93 (80%) were enrolled. Altogether 27% of this trauma population had plasma ethanol concentrations greater than 80 mg/dl. There was a significantly higher prevalence of alcohol intoxication in the group not involved in a road traffic accident (RTA) compared with the group who were involved in a RTA. Initial screening of urine for drugs revealed a prevalence of 51%. After 12 exclusions due to iatrogenic administration of opiates, the final confirmed prevalence was 35% in this trauma population. The individual drug prevalence was 13% for cannabinoids, 11% for codeine, 8% for morphine, 6% for amphetamine, 6% for benzodiazepines, 3% for cocaine, 1% for dihydrocodeine, and 1% for methadone. CONCLUSIONS: There is a notable prevalence of drug and alcohol use in this British accident and emergency trauma population. A significantly higher prevalence for alcohol intoxication was found in the non-RTA group compared with the RTA group. The patterns of drug usage detected reflect local influences and less cocaine use is seen compared with American studies. The association between alcohol, drugs, and trauma, together with ethically acceptable methods of screening, are discussed.

[The effect of ethanol on the deformability and the rheological properties of erythrocytes (author's transl)].

The rheological properties of human erythrocytes were investigated after incubation in ethanol-containing suspensions. Ethanol concentrations were adjusted to the blood ethanol level reached in severe alcohol intoxication. Red cell deformability was measured by the filterability and by viscosimetry of suspended erythrocytes. Red cell deformability becomes significantly decreased by ethanol addition to the suspending media in close connection with the increased osmolarity of the solution. The influence of these alterations on blood viscosity and microcirculation in shocked and non-shocked patients suffering from alcohol intoxication is discussed.

Factors in childhood and youth predicting alcohol dependence and abuse in Swedish women: findings from a general population study.

The aim was to assess risk factors during childhood and youth for alcohol dependence/abuse (ADA) in a population-based study of Swedish women. A total of 316 women were interviewed after stratified random sampling in the general population and a screening questionnaire. The interviews focused on social, psychological and behaviour characteristics as well as on early substance use patterns. Alcohol diagnoses were made according to DSM-III-R and CIDI-SAM. Experiences of sexual abuse before the age of 13 years, a history of psychological or psychiatric problems, early deviant behaviour and an episode of alcohol intoxication before the age of 15 years were significantly associated with ADA in a logistic model. General indicators of low social class were not associated with increased risk of ADA in a multivariate analysis. Sexual abuse in childhood was the strongest predictor of ADA. This association has potential public health importance, and should be addressed in future studies on women and alcohol.

Alcohol and crimes of violence: present issues.

Current issues in alcohol-related violence are highlighted through the examination of correlational studies between alcohol and violent crime. Alcohol is associated with violent crime at a greater than chance level and at a significantly higher level than it is associated with nonviolent crime. Heavy drinking and a verbal argument usually precede the violent act and the victim is as likely as the offender to initiate the altercation. However, it is the precipitator of the altercation who is more likely to be intoxicated. Alcohol and aggression are more strongly related than expected with violent offenders demonstrating psychopathology. Marital violence appears related to alcohol independent of other marital problems. Although there exists a strong correlational relationship between alcohol and violent crime, the nature of the evidence prohibits the establishment of a causal link. In particular, methodological problems, such as a lack of appropriate comparison groups, make it difficult to draw conclusions in this area.

Alcohol effects on movement-related potentials: a measure of impulsivity?

OBJECTIVE: To assess the effects of acute alcohol intoxication on lateralized readiness potential (LRP), a central measure of movement-related brain activity, and the potential association of such effects with personality measures. METHOD: Male volunteers (N = 12) alternated responding hands during a "go/no go" verbal recognition task across all four sessions of the balanced placebo design in which beverage content (either juice only or a vodka and juice mixture that raised the average blood alcohol concentration to 0.045%) was crossed with instructions as to beverage content. RESULTS: Whereas the instructions had no effect on behavioral (response accuracy and reaction time) and physiological (LRP) measures, alcohol decreased reaction times adjusted for psychometer speed. As expected, large LRPs were recorded on "go" trials and were not affected by the beverage. However, the "no go" words that did not require and did not evoke motor responses, also evoked significant LRPs under alcohol but not placebo. Since only trials with correct responses and correct abstentions from responses were included in the averages, the motor preparation was not completed and was terminated before the motor response on "no go" trials. Similarly, there was a decrease in spectral power of the movement-related mu-rhythm on "no go" trials under alcohol. CONCLUSIONS: Alcohol may result in disinhibition such that the "response execution" process is activated based on very preliminary stimulus evaluation. This alcohol-induced brain activity signaling premature motor preparation exhibited correlation trends with personality traits related to impulsivity, hyperactivity and antisocial tendencies, thus concurring with other evidence that indicates commonalities between alcoholism and impulsivity, disinhibition and antisocial behaviors. The LRP on "no go" trials could potentially be used as a psychological index of the impulsiveness induced by alcohol intoxication.
