A fatal concentration of pentobarbital found in a coroner's case where the history had not indicated use of this drug prompted a review of fatalities in Ontario from 2012 to 2015. Coroner's case files, including police and toxicology reports, were reviewed in twenty deaths, in which pentobarbital was identified as the primary cause of death. In all of the deaths (11 females, 9 males), the blood concentration of pentobarbital was greater than 10 mg/L. There were three to eight deaths per year and each was classified as suicide. In 11 cases, there was clear evidence that the drug was purchased over the internet from Mexico or China and imported into Canada. In four cases, it appears that the pentobarbital was labeled as a different, innocuous chemical to facilitate crossing the border without scrutiny. The findings underscore the value of a thorough scene investigation, including details of evidence that may be considered unrelated. 相似文献

“Tampering to Death”: A Fatal Codeine Intoxication Due to a Homemade Purification of a Medical Formulation 下载免费PDF全文
Paolo Fais Ph.D. Nicola Pigaiani M.D. Giovanni Cecchetto Ph.D. Massimo Montisci Ph.D. Rossella Gottardo Ph.D. Guido Viel Ph.D. Jennifer Paola Pascali Ph.D. Franco Tagliaro Ph.D. 《Journal of forensic sciences》2017,62(6):1671-1673
Many homemade tamper processes of medical codeine formulations are available on selected “forums” on the Internet, where recreational codeine users claim to be able to purify codeine by removing additives, such as acetaminophen, to avoid or limit adverse effects. In this work, it is reported and discussed a fatal case of codeine intoxication. The findings of objects such as jars, filters, and tablets, and amounts of unknown liquid material at the death scene investigation suggested a fatal codeine intoxication after the tampering procedure called “cold water extraction.” Toxicological results obtained from the analysis of both the nonbiological material and the body fluids of the decedent integrated with the information collected at the death scene investigation confirmed the above‐mentioned hypothesis. This report underlines the importance of a tight interconnection between criminalistics and legal medicine to strengthen the identification of the cause of death and the reconstruction of the event. 相似文献

This study presents two cases of lethal bentazone poisonings, their clinical presentation, the course of the disease and the autopsy findings. The first is a 50‐year‐old male who had sprayed corn with a solution of bentazone and was admitted to the hospital with sweating, fever, nausea, vomiting of aqueous and hemorrhagic content, and bloody, watery stools. He was treated according to the symptoms including extracorporeal hemodialysis, but eventually suffered from multiorgan failure (acute respiratory failure, acute liver failure, coagulopathy, acute renal failure, metabolic acidosis, and gastrointestinal bleeding) and died 11.35 h after admittance. The cause of death was probable bentazone intoxication. The second case, also a male, aged 49 who committed suicide by ingesting a bentazone solution. He was transferred to the hospital prostrated and cyanotic and died 14.15 h after admittance despite all efforts by the hospital staff. The cause of death was acute bentazone intoxication. 相似文献

Two cases of fatal intoxications with toluene due to glue sniffing are described. In case 1, the autopsy did not indicate cause of death, while in case 2, the cause of death was determined to possibly be due to mechanical asphyxia by drowning. As the decedents had a history of glue sniffing, toxicological analyses were performed. Using gas chromatography with flame ionization detector and gas chromatography/mass spectrometry (GC/MS) with headspace method, toluene was detected in biological samples. Toluene ranged from 3.81 to 20.97 μg/g, with the highest concentrations observed in liver and brain (13.82–20.97 μg/g) in both cases. Based upon this data, the cause of death in both cases was determined to be toluene poisoning. Toxicological investigations are extremely important and should be considered mandatory in all deaths thought to be due to volatile substance abuse, as well as all deaths that are thought to be due to poisoning in young people. 相似文献

Herein, we present a case of 53‐year‐old psychotic woman with acute esophageal necrosis (black esophagus), who was found lying on the floor in the living room of her flat. Pillboxes of antipsychotic drugs were located in the bin. External examination of the body was unremarkable. On internal examination, we found acute esophageal necrosis. Histologically, there was complete epithelial necrosis with focal involvement of muscularis mucosae, dense infiltrate of leukocytes, and ulcerations without any viable cells. There was no evidence of underlying organic diseases or trauma. Toxicological analysis revealed a fatal blood level of antipsychotics (haloperidol, zotepine, and chlorprothixene). Death of the deceased was attributed to fatal intoxication with three various types of antipsychotics. As far we know, this is the first described association between so‐called black esophagus and fatal blood level of neuroleptics. 相似文献

In suicide pact, two or more victims mutually agree and execute to end their lives together by predetermined method, preferably by hanging, drowning, gunshot, or poisoning. The victims are usually spouses, lovers, or friends, and the reasons behind such steps are various. In this reported suicide pact, husband–wife duo jumped from the terrace of a 12‐meter‐high building with their wrist bound to each other. Although they jumped together, the injury patterns were completely different. The man landed on head sustaining mainly craniocerebral injuries, and the wife landed on feet sustaining long bone injuries. They left a suicide note pointing out sudden demise of their only child as the reason for the suicide, and it was signed by both of them. Jumping from a height in suicide pact has not been reported in the scientific literature yet. 相似文献

Abstract: In a public hospital, eight cases of fatal poisoning by nitrous oxide (N2O) occurred under oxygen administration, due to an erroneous swapping of the lines in the gas system. The aim of the study was to clarify the factors involved in asphyxia by characterizing gases from different lines and measuring N2O concentrations in postmortem biological samples from bodies exhumed. Analyses carried out on the gas system confirmed the erroneous substitution of O2 line with N2O and air line with O2. Consequently, high N2O amounts were revealed in several tissues and gaseous biological samples. All specimens were analyzed by headspace gas chromatography technique. A rigorous quantitative analysis was possible only in blood (11.29–2152.04 mg/L) and urine (95.11 mg/L) and in air samples from stomach and trachea (from 5.28 to 83.63 g/m3). This study demonstrates that N2O can be detected in biological samples even 1 month after death. 相似文献

Limited forensic and clinical experience and the lack of confirmatory testing strategies for synthetic cannabinoids (SC) prevent adequate characterization of SC toxicity and the potential impact on public health. A statewide surveillance system identified a fatality involving a 23‐year‐old man found with a large stab wound to the neck following use of a SC product suspected of containing AM2201. Analytical testing for common SCs, SC metabolites, routine drugs of abuse, and over‐the‐counter medications was performed on heart blood obtained at autopsy. Additionally, assays were performed on the SC raw material and drug paraphernalia found on the decedent. High concentrations of AM2201 were detected in all samples. AM2201 metabolites were detected in postmortem blood. Other than a trace amount of JWH‐073 found in smoke residue, no other substances were detected. Psychiatric complications including self‐induced, lethal trauma can occur after the use of SC products. 相似文献

Cannabinoid hyperemesis syndrome (CHS) is one of the more clinically challenging effects of cannabis consumption. It is characterized by cyclic attacks of nausea and vomiting in chronic cannabinoid users and learned behavior of compulsive hot bathing. The deaths of a 27‐year‐old female, a 27‐year‐old male, and a 31‐year‐old male with a history of CHS are reported. The decedents had a history of cyclical nausea and vomiting, chronic cannabinoid use and negative laboratory, radiological and endoscopic findings. All presented to the emergency department with nausea and vomiting in the days preceding death and were treated symptomatically. Toxicological analysis revealed tetrahydrocannabinol in postmortem blood. The cause of death of two of the three cases was attributed to CHS. CHS was appreciated in the third case but was not the cause of death. These three cases demonstrate the importance of recognizing CHS as a potential cause or contributing factor to death in cannabinoid user. 相似文献

Lethal occurrence is exceptional after disopyramide or mianserin poisoning. A case of intentional lethal intoxication with these drugs was reported, as well as a review of the literature. Pre‐ and postmortem blood concentrations of disopyramide or mianserin were assessed in a woman who died from acute cardiac failure after ingestion. The premortem blood concentration of disopyramide alone was considered lethal, and a toxic premortem concentration of mianserin was observed that may have increased cardiovascular failure induced by disopyramide because the metabolism of both drugs is mediated via cytochrome P450. Moreover, it was shown that the postmortem redistribution of disopyramide was limited, as pre‐ and postmortem concentrations were 48 and 65 mg/L, respectively. As regards mianserin, redistribution was observed after death with pre‐ and portmortem concentrations at 0.23 and 0.79 mg/L, respectively. This case illustrates that if postmortem blood concentration of disopyramide is known, the premortem concentration can be deduced. 相似文献

Characteristics of death attributed solely to methamphetamine toxicity (MT, n = 93) by forensic pathologists were examined and compared to cases of multiple drug toxicity (MDT, n = 634). The mean age of MT cases was 36.7 years, and 86.0% were male. Strenuous activity was reported in 12.9%. The most common witness observations were: collapse (60.3%), difficulty in breathing (36.2%), and hyperthermia (27.6%). MT cases had higher blood methamphetamine (0.54 vs. 0.11 mg/L) and amphetamine (0.04 vs. 0.02 mg/L) concentrations and lower likelihoods for opioids (12.5% vs. 80.9%), hypnosedatives (27.3 vs. 60.7%), antidepressants (14.8 vs. 29.8%), and antipsychotics (9.1 vs. 19.7%). MT cases had significantly heavier hearts than MDT cases (423.4 vs. 385.8 g) and were more likely to have cardiomegaly (37.1 vs. 20.4%) and replacement fibrosis (25.7 vs. 14.5%). The clinical picture was of a sudden cardiac event in a middle‐aged man with a high methamphetamine concentration. Cardiovascular signs of heavy methamphetamine use are frequently seen. 相似文献

All cases of fatal oxycodone toxicity presenting to the New South Wales Department of Forensic Medicine over the period January 1, 1999, to December 31, 2008, were retrieved. A total of 70 cases were identified. The mean age was 48.9 years, 58.6% were men, 21.4% were suicides, and in 30% oxycodone had not been prescribed to the decedent. Injecting drug users constituted 27.1% of cases, and oxycodone tablets were injected immediately prior to death by 21.4%. The mean blood oxycodone concentration was 0.40 mg/L (range 0.06-53.00 mg/L). In all cases, psychoactive substances other than oxycodone were also detected, most frequently hypnosedatives (68.6%), other opioids (54.3%), antidepressants (41.4%), and alcohol (32.9%). Preexisting systemic disease was common: cardiovascular (64.2%), pulmonary (49.3%), hepatic (66.7%), and renal (43.9%). 相似文献

Toxicology and characteristics of deaths involving zolpidem in new South wales, australia 2001-2010*
Abstract: All cases presenting to the New South Wales Department of Forensic Medicine between January 1, 2001 and September 31, 2010 in which zolpidem was detected, were retrieved. A total of 91 cases were identified. The mean age was 49.4 years, 65.9% were male, and 61.5% were suicides. Zolpidem was a factor contributing to death in 35 (37.3%) cases, of which 31 (34.1%) involved zolpidem toxicity. The median blood zolpidem concentration was 0.20 mg/L (range 0.05–3.50 mg/L), with no significant gender difference. Drug toxicity cases involving zolpidem had significantly higher median blood zolpidem concentrations than other cases (0.50 vs. 0.10 mg/L). In 83.5% of cases, psychoactive substances other than zolpidem were detected, most commonly antidepressants (46.2%), benzodiazepines (35.2%), opioids (26.4%), and alcohol (39.6%). In summary, zolpidem was a factor contributing to death in a large proportion of cases, predominately involving drug toxicity and suicide. 相似文献

Cleistanthus collinus is an extremely toxic plant poison. We report a case of suicidal ingestion of boiled water decoction of C. collinus where the patient presented with abdominal pain and giddiness. There was persistent metabolic acidosis and fluctuation in the level of serum potassium. The ECG changes indicated a probable myocardial injury with conduction abnormality. At autopsy, the viscera were found to be congested. The toxins were detected in the viscera and blood by TLC and HPLC. Cleistanthin A and B, collinusin, and diphyllin are the principal toxic constituents of the plant. Consumption of a boiled decoction of leaves is highly toxic and, medical management of patients is mainly supportive because the molecular mechanisms of toxin action are unknown. In the recent years, C. collinus has created a considerable amount of interest because of its complex metabolites and their cytotoxic activities. Through this study, the authors have tried to highlight different properties pertaining to C. collinus. 相似文献

In this retrospective study, we report the epidemiological characteristics of all poisoning deaths in Epirus, Greece, from 1998 to 2010; we present the toxicological findings and the statistical evaluation of the results. This is the first detailed scientific report on all the officially certified poisoning deaths concerning part of the Greek population. A total of 126 poisoning fatalities were recorded, 67 of them being mono‐intoxications (53.2%). The cause of poisoning was as follows: drugs of abuse (60%); carbon monoxide (19.8%); pesticides (9.5%); corrosives (4.8%); pharmaceuticals (4.8%); and spider bite (0.8%). The most frequently detected poisonous substances were as follows: heroin (65 cases), ethanol (55), benzodiazepines (42), carbon monoxide (25), cocaine (17), cannabinoids (17) and pesticides (12). Increasing tendency in poisoning death rates was recorded, due to an increase in accidental poisoning deaths attributed mainly to drugs of abuse (total, accidental, and drugs‐of‐abuse poisoning death rates per 100,000 inhabitants per year were 1.87, 1.19, and 0.79, respectively, in the period 1998–2002 and 3.97, 3.41, and 2.55, respectively, in the period 2007–2010). 相似文献

This study will discuss trends in suicide data compiled over 10 years in Dutchess County, NY, from 2004 to 2013. These data were based on reporting and examination standards recommended by the National Association of Medical Examiners and Department of Justice death investigation standards. Almost 300 cases were analyzed in terms of the deceased's gender, age, race, method of suicide, and weapon used. Results from this study agree with other reports showing significant differences for method of death both in terms of age and gender, with men more likely to choose firearms and women more likely to choose overdose. Furthermore, older persons were more likely to commit suicide by firearms, and the younger persons were more likely to commit suicide by overdose. However, other areas, such as method of suicide, differ from national statistics. 相似文献

Abstract: Although many suicide prevention programs focus on youth suicides, data indicate the vast majority of suicides occur among adults (18–64 years). In 2005 New Mexico joined the Centers for Disease Control and Prevention’s National Violent Death Reporting System, collecting data on suicides, homicides, and unintentional firearm fatalities to better inform state and national prevention programs. We utilized data collected by the New Mexico Violent Death Reporting System in its first 2 years of operation (2005 and 2006) in order to define the demographic patterns of adult suicides in the state and characterize risk factors. A total of 526 suicides occurred among adults during this time, with the majority being male (78.5%) and White non‐Hispanic (56.7%). The highest incidence was in adults between 45 and 54 years (28.1%). Firearms were the most commonly used mechanism, and “current depressed mood” the most commonly identified risk factor. High rates of adult suicide indicate the need for targeted prevention programs. 相似文献
