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.     

The effect of witnesses, attorneys, and judges on civil commitment in North Carolina: a prospective study

A total of 388 commitment hearings were observed and analyzed for demographic information on patients, name of judge, duration of hearing, identities of those present and those actually testifying, outcome of any procedural challenges, and concurrence of the judges with attorney and physician recommendations. Age, race, and gender of the patient were found to have no significant effect on the outcome of the cases. Disposition of the cases correlated with recommendations by physicians, witnesses, and state attorneys in an overwhelming number of cases. Possible harmful influences of plea-bargaining in commitment hearings are discussed.     

Brain acetaldehyde and ethanol: method of determination and diagnostic significance in ethanol poisoning

The content of ethanol and acetaldehyde in the limbic cortex and reticular formation of the brain was measured by gas-liquid chromatography in lethal ethanol poisoning. The content of acetaldehyde was significantly increased in the gyrus cinguli of the brain. Lethal poisonings occurred during any stage of ethanol intoxication. The data characterizing individual ethanol tolerance were obtained, which can be used for differential diagnosis of ethanol poisoning in practical forensic medicine.     

Frequency of pulmonary hemosiderosis in Eastern North Carolina

Pulmonary hemosiderosis has been attributed to airborne fungi in water-damaged homes in studies of a cluster of cases in infants and children in Cleveland, Ohio, in 1997. We have searched for such emerging infectious agents in the Coastal Plain of North Carolina, which is subject to intermittent flooding. Pulmonary tissue from 206 infants and young children whose deaths had been investigated from October 1978 to September 1996 was retained at East Carolina University School of Medicine. Ages ranged from premature newborns to 49-months. One hundred and ten deaths were attributed to sudden infant death syndrome (SIDS). New sections were cut and analyzed using hematoxylin and eosin, Prussian blue for iron, and Gomori methenamine silver for fungal organisms. Twenty-three infants and children had iron-containing macrophages. Sixteen of these had underlying illnesses, but 4 were originally diagnosed as SIDS. Only one of these had sufficient hemosiderosis to be considered as having pulmonary hemosiderosis and no fungi were present. One case without iron had fungi and was not originally diagnosed as SIDS. The single case of pulmonary hemosiderosis found in this rural area is not similar to the cluster in Cleveland. The study identifies no fungal organisms as emerging infectious diseases in this area.     

White Supremacist Activity and Crossburnings in North Carolina

This study examines whether the incidence of crossburnings rises in areas where white supremacist organizations, such as the Christian Knights of the Ku Klux Klan, have held rallies or demonstrations. Using data from two public interest groups, Klanwatch and North Carolinians Against Racial and Religious Violence, we track crossburnings and white supremacist activities in 100 North Carolina counties annually for the period 1987–1993. Various statistical models, including an event count analysis that allows each county to have its own level or reporting bias, indicate that the base rate at which crossburnings occur rises sharply in counties where a demonstration has taken place. Since none of the suspected crossburners has apparent ties to white supremacist groups, it may be that white supremacist rallies encourage fellow travelers to engage in this form of racial intimidation.     

Autoerotic deaths: a 25-year retrospective epidemiological study

It is written in almost all articles on autoerotic deaths that these fatalities account for about 500 to 1000 deaths per year in the United States and Canada. However, contrary to the general belief, this incidence rate was not obtained through a study, but it is an estimation based on 30-year unpublished data from Canada and England. In the present retrospective study from 1985 to 2009, 38 cases of autoerotic deaths were identified in the province of Alberta (Canada). This number corresponds to an incidence of 0.56 autoerotic deaths per million inhabitants per year. The vast majority of these deaths are related to typical, predominantly asphyxial methods, such as hanging. The bodies were most commonly found in basements, bedrooms, and bathrooms. There is no clear evidence of a preferential time of day for these deaths, but there appear to be slightly more autoerotic deaths during summer. The incidence of autoerotic deaths is higher in big cities compared with rural areas. The previously published estimate of 500 to 1000 'autoerotic deaths per year should not be used for Canada. An incidence of 0.2 to 0.5 cases per million inhabitants per year is a better estimate of the incidence of autoerotic deaths. The incidence in United States should be reassessed using epidemiological studies.     

Pediatric toxicologic deaths: a 10-year retrospective study

A 10-year retrospective study of pediatric toxicologic deaths was performed at the Medical University of South Carolina (Charleston, SC) from January 1989 to December 1998. During this time, 709 pediatric forensic autopsies were performed on children younger than 18 years of age. Eleven deaths were determined to be secondary to toxic exposures (excluding carbon monoxide poisonings secondary to fires). The remaining deaths were reviewed for the presence of alcohol or illicit drugs. The 11 toxicologic deaths were analyzed for age, sex, race, type of toxic exposure, cause and manner of death, location of incident, witness, and, in the younger age group, the primary caregiver at the time of exposure. The deaths had a bimodal age distribution (6 deaths in victims ages 15 to 17 and 5 deaths in victims ages 4 or younger), involving a wide range of toxins. The teenage group was composed of five males and one female, all white. The preschool group had three females and three males, all black. The manner of death ranged from accidental to suicidal to homicidal. In addition, in eight neonatal and fetal deaths, the victims tested positive for maternal cocaine use, and five of these victims tested positive for cocaine or benzoylecgonine. However, the cause of death was not stated to be cocaine in any of these neonatal and fetal cases.

Acute selenium poisoning: suicide by ingestion

Selenium is a ubiquitous element in the environment essential to the human diet and widely utilized in industrial processes. Fatal human selenium intoxication is rare. The authors report a case in which investigators recovered a bottle of gun-bluing agent beside a 24-year-old man. He exhibited signs and symptoms typical of acute selenium intoxication presenting with nausea and vomiting, followed by pulmonary edema and rapid cardiovascular collapse approximately 3 to 4 h after ingestion. Classic electrocardiographic (EKG) changes, which have been reported to occur in acute selenium intoxication, included sinus tachycardia with ST wave alteration. Toxicological results confirmed elevated blood and tissue concentrations. The cause of death was ascribed to acute selenium intoxication, which ensued rapidly after oral consumption. The manner of death was suicide. This case report, which presents an overview of acute and chronic selenium poisoning, underscores the value of thorough toxicologic analyses of tissue and body fluids in humans.     

Fire and suicide: a three-year study of self-immolation deaths.

Thirty-two self-immolation deaths by fire, representing about 1% of suicides, occurred in the province of Ontario (population 9 million), Canada, from 1986 through 1988. The victims, mostly male (male/female ratio, 26:6), were between 21 and 71 years old (mean age, 38 years). Although the scene of self-immolation was usually familiar to the deceased, some chose remote locations. Eleven were found dead in motor vehicles. An accelerant, usually gasoline, was used in most cases. Many of these individuals had, at some time, indicated their intent to commit suicide, a few by self-immolation, but only about half had a diagnosed psychiatric illness. Most of the victims had a reason to kill themselves, but the factors that motivated them to chose self-immolation by fire were uncertain. Fourteen individuals died in hospitals from severe burn complications. The remainder were found dead at the scene. The postmortem findings of soot in the airway and elevated carbon monoxide in the blood of most of these victims [the carboxyhemoglobin (COHb) concentration was in one case less than 10%, in ten cases greater than or equal to 10 to 50%, and in seven cases greater than 50%] were helpful in determining that the individuals were not only alive at the time of the fire but also that a significant number died from smoke inhalation and carbon monoxide poisoning. The highest levels of carbon monoxide were observed in victims discovered in motor vehicles.     

Asphyxial deaths: a retrospective study and review of the literature

An increasing death rate as a result of violence constitutes a large group in medicolegal autopsies. Specially, deaths due to asphyxia are one of the most important causes in violence deaths.During the 21-year period from January 1984 to October 2004, there were 134 asphyxial deaths autopsied by the Department of Forensic Medicine, Trakya University, Edirne, Turkey. Asphyxial deaths comprise 15.7% of all forensic autopsies; 20.8% of the cases are aged between 30 and 39 years, and the average age was 41.9 years. Males constitute 79.8% of all the cases.The most frequent method of asphyxiation death is hanging (56 cases, 41.8%), followed by drowning (30.5%) and carbon monoxide poisoning (8.2%). More violent methods, such as ligature or manual strangulations, constitute 2.9% and 2.3% of all asphyxial deaths, respectively. Although it was varying according to the methods of asphyxiation, suicide was found to be the manner of death in the majority of the cases.     

Inhalant deaths in South Australia: a 20-year retrospective autopsy study

A 20-year retrospective study of inhalant deaths in South Australia, autopsied at Forensic Science SA, was undertaken from January 1983 to December 2002. Thirty-nine cases were identified from an autopsy pool of 18,880 cases, with a male to female ratio of 12:1. Sixty-four percent of the victims (N = 25) died during voluntary inhalation of volatile substances and 28% (N = 11) committed suicide utilizing a volatile substance or gas. The remaining 3 cases involved a workplace accident (N = 1) and 2 cases of autoerotic death where inhalants were being used to augment solitary sexual activity. The mean age of the 28 victims of accidental inhalant death of 21 years (range, 13-45 years) was considerably less than that of the 11 suicide victims of 31.5 years (range, 17-48 years). No homicides were found. Approximately one quarter of the victims were Aboriginal (N = 11), 10 of whom had died as a result of gasoline inhalation ("petrol sniffing"). Other common substances of abuse were aliphatic hydrocarbons such as butane. The study has shown that those most at risk for accidental or suicidal inhalant deaths were young males, with 92% of victims overall being male, and with 77% of victims being under 31 years of age. Gasoline inhalation remains a significant problem in Aboriginal communities in South Australia.     

Four deaths due to carbon monoxide poisoning in car washes.

In a period of 13 months, three separate incidents of lethal carbon monoxide (CO) poisoning in closed car wash bays resulted in the deaths of 4 white men aged 20 to 36 years. Each man appears to have been intoxicated with mind-altering substances, which may impair judgment, perception of outside conditions, and self-awareness. All four died in winter months. For three men, the deaths were ruled accidental, and for the remaining man, the previous deaths appear to have provided a model for suicide. Warning signs may not be effective to prevent future CO deaths in car washes because of the possible role of intoxication. Mechanical or electronic methods to prevent a bay door from closing completely may be preferable.     

Prevalence and correlates of elder mistreatment in South Carolina: the South Carolina elder mistreatment study

The purposes of this study were to (a) derive prevalence estimates for elder mistreatment (emotional, physical, sexual, neglectful, and financial mistreatment of older adults [age 60 +]) in a randomly selected sample of South Carolinians; (b) examine correlates (i.e., potential risk factors) of mistreatment; and (c) examine incident characteristics of mistreatment events. Random Digit Dialing (RDD) was used to derive a representative sample in terms of age and gender; computer-assisted telephone interviewing was used to standardize collection of demographic, correlate, and mistreatment data. Prevalence estimates and mistreatment correlates were obtained and subjected to logistic regression. A total of 902 participants provided data. Prevalence for mistreatment types (since age 60) were 12.9% emotional, 2.1% physical, 0.3% sexual, 5.4% potential neglect, and 6.6% financial exploitation by family member. The most consistent correlates of mistreatment across abuse types were low social support and needing assistance with daily living activities. One in 10 participants reported either emotional, physical, sexual, or neglectful mistreatment within the past year, and 2 in 10 reported mistreatment since age 60. Across categories, the most consistent correlate of mistreatment was low social support, representing an area toward which preventive intervention may be directed with significant public health implications.     

Accreditation and the state of North Carolina: The revitalization of national standards

From the mid to late 70s, the Academy of Criminal Justice Sciences (ACJS) developed a process for accrediting post-secondary criminal justice education programs. The academy gave form to the program by developing guidelines and a complex organizational network. However, the program did not reach fruition for a variety of economic and political reasons and it is doubtful that the Academy will attempt to resurrect the program soon. Even though the accreditation movement was abandoned on the national level, the North Carolina Association of Criminal Justice Educators (NCACJE) decided to implement the program and stepped into a very lengthy and political process.     

Under-recording of ethanol intoxication and poisoning in cause-of-death data: causes and consequences

In the present study we examined how consistently and completely the role of acute alcohol (ethanol) intake as a cause of death is reported on death certificates, how complete and specific the statistical recording of cause-of-death data on acute alcohol-induced deaths is, and how the information ultimately appears in the national mortality statistics. Data on all alcohol-positive deaths with blood alcohol concentration of ≥ 0.5‰ (g/kg) in Finland in 2005 (N = 2348) were reviewed. Overall, a concentration-dependent association was found between forensic-toxicologically determined blood alcohol concentrations and acute alcohol-specific cause-of-death diagnoses. Based on a medico-legal re-evaluation of death certificates, acute alcohol-specific causes were found to be underreported nationally at a rate of 8%. For accidental alcohol poisonings alone, the figure was about 1%. This underreporting was not corrected during recording of the cause-of-death data, though individual corrections and changes were observed. Especially, recording of multiple causes suffers from this underreporting of acute alcohol-specific causes. ICD-10 seems to do well in fulfilling the demands for a specific classification of uncomplicated alcohol poisoning. In combined alcohol-drug poisonings, however, ICD-10 shows a bias towards drugs over alcohol, even when alcohol has been specified and reported as the most toxic component by the medico-legal pathologist. Since the national statistics is based on the underlying causes, this state of affairs is likely to result in the underestimation of the role of acute alcohol intake as a cause of death. This observation of underreporting of acute alcohol-specific causes on death certificates should result in a harmonisation of education and principles and practices used in death certification. To increase the coverage and specificity of mortality statistics, based on the underlying causes of death, the coding of all components of alcohol-drug combinations and their classification according to the most important intoxicant or combination of intoxicants is recommended.     

On the importance of a comprehensive study for diagnostics of death from acute ethanol poisoning and coronary heart disease

Over 30 000 cases of acute poisoning with ethyl alcohol and its surrogates are recorded annually in this country. Differential diagnostics between fatal poisoning and death from coronary heart disease encounters serious difficulties. The authors report a comprehensive forensic chemical, morphometric, and pathomorphological study of the activity of ethanol-oxidizing enzyme systems in the internal organs. The results of histochemical examination provide a basis for the extension of diagnostic potential of the available methods and the enhancement of the objective value of expert reports.
