Unnatural and Violent Death in Cases with High Blood Alcohol Concentration- Autopsy Study

Introduction. Sudden natural death occurs unexpectedly in apparently healthy subjects, or in persons during an apparent benign phase in the course of disease. The most common cause is sudden cardiac death, which is sometimes the first and last manifestation of coronary heart disease. Alcohol directly influences excitation of myocytes, and therefore provokes arrhythmias and possibly, sudden cardiac death. Objective. To establish the frequency of sudden cardiac death in cases of acute alcohol intoxication, to determine blood alcohol concentration at the moment of death, and to determine frequency and level of ethanol intoxication in chronic alcohol abusers, as well as causes of sudden death in those cases. Method. Retrospective autopsy study was performed for a three-year-period. We analyzed cases of sudden natural death, in relation to age and gender, cause of death, and blood alcohol concentration (at least 0.5 g/L). We considered the person to be a chronic alcoholic abuser if gross examination of organs during autopsy showed changes typical for excessive and habitual alcohol consumption. Results. Our sample consisted of 997 cases: 720 men and 277 women, average age 62.0?15.2 years (min=11; max=98). Total of 753 of them died of sudden cardiac death: much more men (?2=167.364; p=0.000), significantly younger than women (t=6.203; p=0.000). We determined acute alcohol intoxication in 73 persons - average blood alcohol concentration 1.85?1.01 g/L (min=0.55; max=3.85), and 61 of them died of cardiovascular diseases (?2=236.781; df=5; p=0.000). Conclusion. In our observed sample, not many persons were under acute alcohol intoxication (around 7%). Most commonly, they were chronic alcohol abusers who died due to exacerbation of chronic heart disease, mildly or moderately intoxicated - the younger, the drunker.

Introduction. The body cooling process goes through few clinical phases. These are followed by some morphological thanatological changes such as frost erythema and Wischnewsky's spots, which are used in diagnosis of death due to hypothermia. In such cases there is no any specific autopsy finding. Objective. To establish the frequency of hypothermia as the cause of death for a ten-year-period, and to analyze the sample according to gender and age, risk factors and autopsy findings of subjects. Methods. A retrospective autopsy study was performed for a ten-year-period (total of 12,765 forensic autopsies). The relevant data were collected from autopsy records, police reports and heteroanamnestic interviews. The sample was analyzed according to gender, age, scene of death, blood alcohol concentration, risk factors, and autopsy findings of all observed subjects. Results. The sample included 67 subjects, 42 males and 25 females (?2=4.31; p<0.05), of average age 63.9?14.7 years (min=27, max=92; med=65, mod=55). Nineteen of subjects were found at in-door places. In 13 subjects blood alcohol concentration ranged from 0.50 to 3.32 promille (average 1.81?0.93). The younger the observed subject was, the higher the blood alcohol concentration (?=-0.251; p=0.04). One third of the observed subjects were chronic alcohol abusers. Thirteen persons had psychiatric diseases. In 43 observed subjects the concomitant appearance of frost erythema and Wischniewsky's spots were established (?2=49.59; df=3; p<0.001). Conclusion. In the analyzed ten-year period hypothermia was not often the cause of death; it was disclosed only in 0.5% of the total number of the studied autopsies. The most of the deceased were older males with cardiovascular problems found in unprotected open-air places. The most frequent thanatological findings in the analyzed subjects were frost erythema and Wischnewsky's spots.

Blood Alcohol

Introduction: The tendency to impulsive behaviors and/or violence is exacerbated after alcohol consumption. Still, the relation between alcohol/violent deaths reported in the literature is not accurate, and in general, alcohol is only seen as a trigger to aggressive actions. The relationship of the victims with their blood alcohol is less studied. They were especially concerned about the role of alcohol as a risk factor for victims of unnatural death. Thus, our goal is to check the influence of alcohol in victims of violent deaths as homicides, suicides, and accidents. Materials and methods: Retrospectively the medical records of 805 autopsies performed at the Institute of Forensic Medicine (IML) of Franco da Rocha, in the period 2001 to 2017 were reviewed. The variables studied were sex, age, types of violent death rates, and alcohol - these were considered positive when above 0.3 mg/ml. The dosage of blood alcohol concentration (BAC) was performed using samples of 10 ml of blood collected at necropsy, is preferably taken from the cardiac chambers or of the right femoral vein. Dosages of alcohol in blood samples were done in the Forensic Toxicology Center of the IML by gas chromatography, using the technique of separation “headspace” and double column. Results: Drug testing for alcohol was available for 488 (79.1%) of 617 necropsies. Of the 617 subjects studied, 532 (85.7%) were male, and 85 (13.8%) were females (with high rates of adolescents). The vast majority (n = 230) were killed, and 40.5% of victims had BAC above 0.3 mg/ml of blood. Traffic accidents came next, accounting for 181 deaths, with 41% of victims presenting positive BAC. Discussion: High blood alcohol levels of the victims were associated mainly with the genesis of accidents (drowning, falls, traffic, aspiration/ smothering) and murder (with impaired ability to resist or by causing the release of impulses to engage in violent situations), about 40% of cases. Conclusion: Our results indicate that alcohol abuse is a risk factor for victims of violent death. In these cases, alcohol has two types of action. Direct: contributes to accidents of various kinds - from traffic by decreasing powers of concentration, attention, and loss of reflexes, to other types of accidents such as drowning, falls, swallowing disorders causing airway obstruction, and mechanical asphyxia. And they were indirect, making it easier for individuals to engage in conflict (and thus become victims of crimes).

Considering the growing number of requests from the criminal investigations authorities addressed to the institutions of legal medicine, testing of blood alcohol concentration both in the living person and in the corpse, we believe that a presentation of the two methods which are used in our country, is a topic of interest at present. The purpose of this article is to provide the reader with the technical details on how blodd alcohol concentration is realised by means of the gas chromatographic method and the classical one, (Cordebard modified by D. Banciu and I. Droc) respectively. Another purpose of this article is to also show, in a comparative way, the elements that make the gas chromatographic method superior to the former one.

And Performance

There is a large body of research that documents the impairing effect of alcohol on driving behavior and performance. Some of the most significant alcohol influence seems to occur in divided attention situations when the driver must simultaneously attend to several aspects of the driving task. This paper describes a driving simulator study of the effect of a low alcohol dose, .055 BAC (blood alcohol concentration %/wt), on divided attention performance. The simulation was mechanized on a PC and presented visual and auditory feedback in a truck cab surround. Subjects were required to control speed and steering on a rural two lane road while attending to a peripheral secondary task. The subject population was composed of 33 heavy equipment operators who were tested during both placebo and drinking sessions. Multivariate Analysis of Variance showed a significant and practical alcohol effect on a range of variables in the divided attention driving task.

Driving Scenario

This article describes a drink-driving scenario where a woman was apprehended for driving under the influence (DUI) with a blood alcohol concentration (BAC) of 256mg/dl1 The correctness of this result was vigorously challenged by a medical expert witness for the defence, who was actually a specialist in alcohol diseases. Despite reanalysis to confirm the BAC as well as a DNA profile to prove the identity of the blood specimen, the woman was acquitted of the charge of drunk driving by the lower court. However, she was subsequently found guilty in the High Court of Appeals with a unanimous decision and sentenced to four weeks imprisonment. This case report illustrates some of the problems surrounding the use of expert medical evidence by the defence to challenge the validity of the prosecution evidence based solely on a suspect's BAC. In situations such as these, an expert witness should be called by the prosecution to clarify and, if necessary, rebut medical and/or scientific opinions that might mislead the court and influence the outcome of the trial.
