Death in sauna

Bathing in sauna is common in Finland, where there are approximately 2 million saunas among the population of 5.2 million. In this paper, deaths occurring while in a sauna in 1990-2002 in Finland were studied by analyzing police and forensic autopsy reports, death certificates, and toxicological results. The annual rate of death occurring while in a sauna was less than 2 per 100,000 inhabitants. Close to half (51%) of the cases were determined to be natural deaths and exposure to heat was the cause of death in 25%. Overall, 50% of all cases were under the influence of alcohol. The main conclusion is that death in the sauna is a rare event even in Finland where the frequency of sauna bathing is high. The role of alcohol as a risk factor has grown. The prevention of these deaths should focus on less drinking of alcohol and avoid leaving a drunken bather alone in the sauna.     

Evaluation of certifier practices regarding alcohol-related deaths: Fulton County Medical Examiner's Center, Atlanta, Georgia, 2004

CONTEXT: Alcohol can contribute to various manners of death by acute intoxication that places a person at risk for fatal injury, acute fatal alcohol poisoning, or the various fatal complications of chronic abuse with or without superimposed acute intoxication. The reporting of alcohol use on the death certificate may vary with office policy or procedure, certifier judgment, and the timing of information received during investigation. OBJECTIVE: To determine the number of deaths including mention of alcohol use in the investigative case file, the number of death certificates on which alcohol use is reported, the number of discrepancies between the 2, and the possible reasons for observed discrepancies. DESIGN, SETTING, AND PARTICIPANTS: Retrospective case review of all deaths where alcohol use was mentioned in the investigative case file and/or on the death certificate for deaths investigated by the Fulton County Medical Examiner in Atlanta, Georgia, during a 1-year period between January 1, 2004, and December 31, 2004. MAIN OUTCOME MEASURES: Percentage of deaths with alcohol use reported on the death certificate, tabulation of where and how alcohol use is reported on the death certificate, and tabulation of the differences between the investigative case file and death certificate regarding alcohol's possible role in causing death. RESULTS: Among the 1324 deaths certified by the office, 105 (8%) had alcohol use reported on the death certificate. The majority (67%) of these cases were natural deaths. Sixty-nine (5%) deaths had mention of alcohol use in the investigative case notes but did not include it on the death certificate. Twenty-five (2%) deaths had mention of alcohol on the death certificate but did not have mention of it in the investigative case file based on our search criteria. However, subsequent review of additional case follow-up information disclosed a history of alcohol use or acute intoxication in each case. CONCLUSIONS: The data show that more natural deaths are considered to be directly caused by alcohol than other manners of death. For the unnatural manners of death (excluding acute alcohol poisoning), alcohol use is often viewed by medical examiners as an incidental, associated finding or risk factor surrounding the circumstances of death rather than being an actual cause of death. In such cases, alcohol use is often omitted from the death certificate. For deaths directly caused by alcohol, the proportion of cases involving possible underreporting or overreporting of alcohol involvement was relatively small and usually involved the omission of chronic alcohol use from the death certificate. Researchers need to be aware of potential limitations of death certificate data for studying alcohol-related deaths.     

Relationships between the deinstitutionalization of healthcare for patients with mental disorder, substance abuse, and isolated death

Isolated death (ID) (i.e., dying alone without anyone noticing for several days) has been suggested to be related to social isolation, mental disorder, and alcohol and/or drug abuse. A major transfer of patients with a mental disorder and/or alcohol and/or drug abuse from institutionalized care to treatment as outpatients has been enacted in Sweden during the past decade. On the basis of the assumption that such deinstitutionalization is likely to result in increased social isolation, our working hypothesis was that the incidence of ID among patients belonging to these categories has increased in Sweden. The present study involved all deaths subjected to a medicolegal examination in Stockholm County (with a population of approximately 1.9 million people) during the period 1992-2000. The pattern of ID (defined as cases involving a postmortem delay between death and discovery of at least 1 week), as well as the incidence of fatalities subjected to medicolegal examination with a record of mental disorder and/or alcohol and/or drug abuse was evaluated. Throughout this period, the proportion of the deceased with a record of a mental disorder was high among all the cases examined and higher still among the cases of ID, especially among those younger than 65 years of age. There was a rather limited increase in the incidence of ID and a much more pronounced increase in the number of former psychiatric patients whose deaths were subjected to medicolegal examination, but did not satisfy the criteria for ID. A record of alcohol and/or drug abuse was more common than a diagnosis of mental disorder among both the males and females who died at an age of less than 65, with a clear difference between the cases of ID and non-ID in the case of men. There was no significant increase in incidence over the course of this study. Thus, this study reveals a slight increase in the number of IDs and a more pronounced increase in the number of medicolegal examination of non-IDs of individuals with a record of a mental disorder.     

Psychological factors in the determination of suicide in self-inflicted gunshot head wounds

Self-inflicted contact gunshot wounds to the head have usually been considered presumptive of suicide. This study evaluates whether sufficient psychological data are gathered in such cases to support a manner of death determination of suicide. We suggest that law enforcement agencies and coroner's departments do not fully explore the decedent's state of mind at the time of death. We studied the first 50 consecutive deaths in 1993 in a major metropolitan county due to self-inflicted gunshot wounds to the head. The sample consists primarily of unmarried, white males, with a median age of 35 years, who displayed psychiatric disturbance, primarily depression, before their death. Younger individuals were often under the influence of alcohol and/or drugs at the time of death. Stressors, such as the loss of a loved one, are common among young and middle-aged persons, while serious health problems are found among the majority of middle-aged and elderly individuals. Many of the findings of this study are consistent with the literature regarding individuals who commit suicide. Although data on many important psychological risk factors are missing in most cases, sufficient psychological material is gathered about the decedent's mental condition at the time of death to support a suicide determination.     

Acute lethal alcohol intoxication (author's transl)]

In 14,744 autopsy cases from an 18-year period 92 cases (of which 7 were ruled out because of decomposition were observed in which death was supposed to be due to direct acute alcoholic intoxication. In the police reports 81 persons were designated as chronic alcoholics or abusers of spirits. The blood alcohol level ranged between 2.04 and 4.92 o/oo. The cases studied were divided into two groups, one with low and the other with high lethal alcohol level. Fatty liver and cirrhosis were found with identical frequency in the two groups, whereas cardiac hypertrophy of obscure origin occurred markedly more often in the group with low lethal blood alcohol level. On the basis the possible mechanism of death in the cases with cardiac hypertrophy is discussed. Finally, the relation between the blood and urine alcohol concentrations observed in 72 cases is discussed. On the assumption that the water phase of the blood was 75 per cent of the total blood, death occurred in the persons without cardiac hypertrophy with fairly identical frequency either in the phase of absorption or the phase of elimination, whereas in the persons with cardiac hypertrophy death most often occurred in the phase of absorption. These statements should, however, be taken with some reservation, partly because the water phase of the blood may vary considerably post mortem (60-90 per cent) and partly because the urine alcohol concentration depends on serval variable factors.     

Forensic appraisal of death due to acute alcohol poisoning: three case reports and a literature review

Death due to acute alcohol poisoning lacks specific anatomical characteristics, compared with other deaths due to drug poisoning. We report three forensic cases of death from acute alcohol poisoning due to inhibition of the respiratory centre and eventual asphyxia. Blood alcohol concentrations in the three fatalities were 5.28, 3.33 and 3.78 mg/mL, respectively. Lethal doses and blood alcohol concentrations showed differences between individuals. Detailed auxiliary tests besides autopsy were undertaken. These cases show that forensic scientists should exclude other causes of death, combine the autopsy with auxiliary tests, and then make an appraisal.     

Mallory-Weiss syndrome as the cause of sudden, unexpected death

The Mallory-Weiss-syndrome is an upper gastrointestinal haemorrhage due to longitudinal mucosal lacerations in the oesophagogastric junction. The mucosal lacerations occur as a sequel of vomiting or any other increase in intraabdominal pressure and account for up to 15% of all upper gastrointestinal bleedings. If death is due to a bleeding Mallory-Weiss-tear, however, massive blood stains on the corpse and around it frequently give rise to the suspicion of an unnatural cause of death. For this reason, autopsy is usually indispensable to elucidate the circumstances in which death occurred. The authors carried out a retrospective analysis of 5958 autopsies performed between 1997 and 2001 at the Institute of Legal Medicine, University of Hamburg, in order to identify all cases of Mallory-Weiss-syndrome as cause of sudden, unexpected death. The results (9 cases, amounting to 0.15% of all autopsies) suggest that Mallory-Weiss-syndrome is probably much more common as a cause of sudden death than previously described. Regarding epidemiological aspects, men clearly predominate; the average age was 48 years. It should also be stressed that in 8 of the 9 cases there was a previous history of chronic alcohol abuse.

The epidemiology of sudden infant death syndrome in Finland in 1969-1980

SIDS cases were defined by examining all death certificates, in which sudden deaths were expected to be found from the years 1969-80 from the Central Statistical Office of Finland. The age limits were 28-364 days. If the death certificate did not give enough information as to whether the cause of death was explained or unexplained, autopsy records and microscopic specimens were examined. If the death was sudden, but no autopsy was done, no microscopic specimens were taken, or there were some slight findings which could have partly explained the death were classified as borderline cases. The mean annual incidence of SIDS in Finland was 0.41/1000 livebirths in 1969-80. In 1969-74 and 1975-80 the incidences were 0.31 and 0.51, respectively. The increasing tendency of SIDS was partly due to more borderline cases in the first period and partly due to more twins, and infants with small birth weight, dying of SIDS in the second period. Deaths at weekends and sleeping with parents in the second period were more common than in the first study period. In the SIDs group the young maternal age, low social class, family type unmarried couple or single mother, maternal anemia during pregnancy were more common than in the control group. Mothers of SIDS infants had more previous children and fewer visits and later first visit to prenatal clinics than control mothers. The duration of gestation was shorter and the mean birth weight and length were smaller in the SIDS case than in the control group. Twins were more common among SIDS infants than in the common population. The most important risk factor of SIDS was maternal smoking during pregnancy. The epidemiological results conform with the hypoxia hypotheses.     

Psychosocial Complications of Crohn's Disease and Cause of Death

Patients who suffer from Crohn's disease are prone not only to the complications of a relapsing, unpredictable disease, but also to feelings of stigmatization; depression; and increased risk of suicidal ideation, suicide, or drug and alcohol abuse. Cases performed at the Jackson County Medical Examiner's Office from 2008 to 2010 were reviewed. Autopsy findings, investigator reports, toxicology results, medical records, and interviews with survivors were analyzed. Twelve cases of Crohn's disease were recovered. In 10 of these cases, inflammatory bowel disease was not the cause of death. Instead, psychosocial consequences of the disease had significant implications in the deaths. The mean age of decedents was 45 years, with a female predominance. In eight cases, the decedents lived alone. Five patients had issues of acute or chronic drug or alcohol use. Five patients committed suicide. These cases underscore the role of psychosocial factors that can contribute significantly to the cause of death in patients with Crohn's disease.     

Ethanol production by Candida albicans in postmortem human blood samples: effects of blood glucose level and dilution

We present two cases in which the ethanol concentration in blood samples taken after death continued to increase in the absence of any remarkable increase in n-propanol concentration. Species of bacteria and yeasts, including Candida albicans were isolated from these samples. We then examined whether C. albicans, the most common yeast in the general environment, was able to produce ethanol in human blood stored at room temperature. Ethanol production increased as the glucose concentration increased, indicating that C. albicans produced ethanol from the glucose. Our results also suggested that C. albicans produced ethanol more easily in blood diluted by intravenous infusions that included glucose than in undiluted blood. These findings are useful for the evaluation of postmortem ethanol production in subjects whose blood has been diluted by infusions with glucose. Furthermore, there was no quantitative relationship between the amount of n-propanol detected and the amount of ethanol production: n-propanol appears to be an unreliable index of putrefaction and postmortem ethanol production by C. albicans. It is possible for the blood ethanol level to be high and n-propanol not to be detected, even if the subject has not been drinking alcohol. We reconfirmed the necessity of immediately adding sodium fluoride to samples for ethanol analysis to prevent postmortem ethanol production.     

Suffocation using plastic bags: a retrospective study of suicides in Ontario, Canada

One hundred and ten cases of suicidal suffocation using a plastic bag were identified in the files of the Office of the Chief Coroner of Ontario, Canada, between 1993 and 1997. The records were reviewed to determine the demographic characteristics of this group compared with all cases of suicide in Ontario, the scene information, autopsy findings and toxicology results. Most suicides occurred in people over 60 years of age, with older women making up a considerable proportion of cases as compared with other methods of suicide. In 40% of cases the deceased was suffering from a serious illness. Autopsy findings were usually minimal, with facial, conjunctival and visceral petechiae present in a minority of cases. One or more drugs were detected in the blood in 92.6% of cases where toxicologic testing was performed. Benzodiazepines, diphenhydramine and antidepressants were the most common drugs found, with diphenhydramine the most common drug present at an elevated concentration. Information at the scene from "right to die" societies was uncommon. One quarter of decedents took additional measures, besides the use of drugs or alcohol, to ensure the rapidity, certainty or comfort of their death. This study further elucidates the characteristics of this uncommon method of suicide. It emphasizes additional scene findings, such as the presence of dust masks, physical restraints and modification of the plastic bag that may be of use to death investigators in determining the correct manner of death.     

Diagnostic dilemma of sudden deaths due to acute hemorrhagic pancreatitis

Sudden death due to acute pancreatitis has been rarely determined. A review of 3305 autopsies performed between 1991 and 2001 at the Council of Forensic Medicine found 12 cases (0.36%) with sudden death due to acute hemorrhagic pancreatitis without symptoms. A history of chronic alcohol ingestion was obtained from family in four cases (33%), and no stones were found in the bile ducts or in the gall bladders. During the autopsies, hemorrhage and edema were localized on the head of the pancreas in three cases and the whole pancreas in nine cases. The most common extrapancreatic pathology was found in the lung including pulmonary edema, alveolar hemorrhage, pleural effusion, and pulmonary congestion. There was no correlation between pulmonary and pancreatic damage. It is suggested that the forensic pathologists who are dealing with sudden unexpected death must not ignore the examination of pancreatic and extrapancreatic regions to avoid missing acute pancreatitis.     

Ischemic heart disease and epilepsy: two major causes of out-hospital natural death in male alcoholics

The objectives of this research were to study the distribution of in- and out-hospital deaths and causes of death in male alcoholics and in particular to analyze obscure cases. In a population-based sample of 1123 men treated in one detoxification unit during 1986–1989, 97 patients with alcohol dependence (DSM-III-R) died ≤ 1 year after in-hospital detoxification. In each case, the cause and the manner of death were assessed by scrutiny of information in hospital and autopsy records, toxicological examinations, and police reports. The results were that 71 of the 97 men died outside hospital. The overall autopsy rate was 89%. Ischemic heart disease accounted for 18 out of 41 evaluable natural out-hospital deaths. Epileptic seizures were judged to be the cause of death in five cases and could also have contributed to seven out of eight obscure out-hospital deaths. Ethanol in blood or urine was detected in 19 of the 23 deaths attributed to trauma or intoxication, whereas only four out of the 18 out-hospital deaths from ischemic heart disease were ethanol-positive. It was concluded that early detection and adequate treatment of ischemic heart disease and epilepsy might improve prognosis in patients with alcohol dependence. The use of clinical information could be of crucial importance in evaluating possible causes of death, especially in obscure cases.     

Toxicology and circumstances of death of homicide victims in New South Wales, Australia 1996-2005.

To determine the prevalence and circumstances of psychoactive substances amongst homicide victims, 485 consecutive cases autopsied at the NSW Department of Forensic Medicine (1/1/1996-12/31/2005) were analyzed. Substances were detected in 62.6% of cases, and illicit drugs in 32.8%. Alcohol, cannabis, opioids, and psychostimulants were most commonly detected. Alcohol and cannabis were both more prevalent amongst males. Mean ages were significantly younger for decedents who tested positive for a substance and for an illicit drug. Cases where death resulted from a physical altercation were more likely to have had alcohol and cannabis present. Illicit drugs were prominent amongst firearms deaths. The proportion of alcohol positive cases increased from 25.0% on Monday to 49.4% for Saturdays/Sundays. Alcohol was more common in incidents in the 0001-0600 h and 1800-2400 h periods. Psychoactive substances appear to substantially increase the risk of homicide, although there are important differences between drug classes in the circumstances of such incidents.     

Suicide Case Due to Phosphoric Acid Ingestion: Case Report and Review of Literature

Ingesting caustic substances represents a common event which may result in serious injuries of the gastrointestinal system. Severity of injury depends on the type of ingested substance: Caustic burns are more frequently associated with acid ingestion and their severity depends on type, concentration, time of exposure, and amount of the ingested substance. We report a case of phosphoric acid ingestion leading to death in a patient with depressive disorder. While reports ingestion of other acids and organophosphates can be found in the literature, there are no reports detailing a death due to phosphoric acid ingestion. We hope that presenting the findings in this case can aid death investigators in future cases that may involve ingestion of such a substance. After autopsy pH, phosphate and calcium ions concentration in the blood were analyzed. The cause of death was due to systemic effects: metabolic acidosis, hypophosphatemia, hypocalcemia, and hyperkalemia.     

Sudden epilepsy deaths and the forensic pathologist

Sudden unexpected deaths in epileptic persons are not rare events, most commonly encountered by the forensic pathologist rather than the clinician. Such deaths may represent 1-1.5% of all "natural" deaths certified by the medical examiner or coroner. The typical victim is a black male about 30 years of age who tends to abuse alcohol, with a history of generalized epilepsy for more than 1 year and likely for more than 10 years. There are a lack of obvious anatomic causes for the death at autopsy, but 60-70% of cases will have a lesion in the brain (most commonly old trauma) to explain the epilepsy. Most victims have no blood levels of anticonvulsant medications at the time of death. We have evolved a form for use by medical examiner/coroner's investigators at the scene to collect relevant information which will be of assistance to the pathologist in interpreting the case. Estimated prevalence of sudden epilepsy death, mechanisms, and other features of such cases are reviewed briefly.     

Influence of alcohol intoxication of pedestrians on injuries in fatal road accidents

Pedestrians belong to the group of road users with the highest mortality rate. The frequency of road accidents involving pedestrians is 2% but pedestrians represent as many as 13% of all road accident deaths. Because of the mechanism and dynamics of injury and the effects of alcohol on physical and mental performance, pedestrians under the influence of alcohol are classed among the road users most at risk.Our retrospective study included 125 pedestrian fatalities treated at the Institute of Forensic Medicine, Faculty of Medicine, University of Ljubljana between 1999 and 2006. We classified the victims into two groups by blood alcohol level Group I (alcohol positive) and Group II (alcohol negative), defined differences in gender, age, incidence of injuries and established causes of death and period of survival following the road accident. In Group I (n = 53) 96% were male and 4% female; the average age was 45.6 years. In Group II (n = 72) 40% were male and 60% female; the average age was 63.1 years. The percentage of injuries to individual parts of the body was higher in Group I than among the deceased pedestrians in Group II. The most common cause of death in both groups was craniocerebral trauma. Death occurred in the first 6 h following the accident in 92% of cases in Group I and in 69% of cases in Group II.Alcohol-positive pedestrians are predominantly younger men, who have a higher level of risk of a road accident, greater incidence of injuries and a shorter period of survival following a road accident.     

Toxicology and Circumstances of Death of Homicide Victims in New South Wales, Australia 1996–2005

Abstract:  To determine the prevalence and circumstances of psychoactive substances amongst homicide victims, 485 consecutive cases autopsied at the NSW Department of Forensic Medicine (1/1/1996–12/31/2005) were analyzed. Substances were detected in 62.6% of cases, and illicit drugs in 32.8%. Alcohol, cannabis, opioids, and psychostimulants were most commonly detected. Alcohol and cannabis were both more prevalent amongst males. Mean ages were significantly younger for decedents who tested positive for a substance and for an illicit drug. Cases where death resulted from a physical altercation were more likely to have had alcohol and cannabis present. Illicit drugs were prominent amongst firearms deaths. The proportion of alcohol positive cases increased from 25.0% on Monday to 49.4% for Saturdays/Sundays. Alcohol was more common in incidents in the 0001–0600 h and 1800–2400 h periods. Psychoactive substances appear to substantially increase the risk of homicide, although there are important differences between drug classes in the circumstances of such incidents.     

Mitral valve prolapse syndrome as cause of sudden death in young adults

Mitral valve prolapse syndrome (MVPS) is a relatively common disorder of the mitral valve and most cases take a benign clinical course. Only a subset of patients develop severe clinical symptoms such as arrhythmia, insufficiency of the mitral valve or infective endocarditis. As a consequence, sudden death might occur in these patients, thought to be caused by an arrhythmogenic event. By presenting six cases of sudden unexpected death in young female adults, we point at clinical and pathological data from the literature, which are of interest from the viewpoint of legal medicine. The incidence of MVPS in autopsy series has been reported to be about 4-5%, while clinical data hint at an incidence of about 2.5%. The presented cases suggest that even clinically benign cases of MVPS in young adults might result in sudden unexpected death. Such cases are not included in hospital based studies on the topic. This might lead to an underestimation of the fatal risk associated with the disease, even if sudden death might be a rare event in MVPS.
