Amphetamine derivative related deaths

Amphetamine its methylendioxy (methylendioxyamphetamine methylenedioxymethylamphetamine, methylenedioxyethylamphetamine) and methoxy derivatives (p-methoxyamphetamine and p-methoxymethylamphetamine) are widely abused in Spanish society. We present here the results of a systematic study of all cases of deaths brought to the attention of the Madrid department of the Instituto Nacional de Toxicologia from 1993 to 1995 in which some of these drugs have been found in the cadaveric blood. The cases were divided into three categories: amphetamine and derivatives, amphetamines and alcohol, amphetamines and other drugs. Data on age, sex, clinical symptoms, morphological findings, circumstances of death, when known, and concentration of amphetamine derivatives, alcohol and other drugs in blood are given for each group. The information provided here may prove to be useful for the forensic interpretation of deaths which are directly or indirectly related to abuse of amphetamine derivatives.     

Fentanyl-related deaths: demographics, circumstances, and toxicology of 112 cases

Since 1979, the potent narcotic analgesic fentanyl and its analogs have been synthesized in clandestine laboratories and sold as heroin substitutes. At least 112 overdose deaths have been associated with their use. In this study, toxicology data, autopsy findings, and coroners' investigative reports were reviewed in order to construct a profile of the typical fentanyl overdose victim and to identify any factors that might heighten the risk of death from fentanyl use. The "typical" fentanyl overdose victim was 32.5 +/- 6.7 years of age (range, 19 to 57 years), male (78%, compared with 22% female), and Caucasian (50%, compared with 29% Hispanic, 20% Black, and 0.9% Asian). With the exception of his or her age, the typical fentanyl overdose victim is quite similar to the typical heroin user. Nearly all the deaths (94%) occurred in California, yet within the state they were widely distributed throughout 17 counties and 44 cities. Pulmonary edema and congestion and needle puncture sites were consistent postmortem findings. No preexisting medical conditions were identified as possible risk factors. Although most of the fentanyl victims had a prior history of intravenous drug use, morphine or codeine were not commonly found, which suggests that the victims had little or no opiate tolerance. Ethanol was present in 38% of the cases and is thought to be a significant risk factor. Mean fentanyl concentrations in the body fluids were quite low: 3.0 +/- 3.1 ng/mL (0.3 +/- 0.31 micrograms/dL) in blood and 3.9 +/- 4.3 ng/mL (0.39 +/- 0.43 micrograms/dL) in urine, measured by radioimmunoassay. Although the potency of the analogs and the purity of street samples varies considerably, it is probably the general availability of the drug rather than the potency of a particular analog that determines the incidence of overdose deaths.     

Amphetamine derivative related deaths in northern Greece

Until 1997, only one amphetamine related derivatives (AMPs) fatality had been reported in Greece. Since then, amphetamine (AMP) or AMPs have been found in seven out of 1,500 post-mortem toxicological cases. The cause and manner of death of these seven cases were: 3,4-methylenedioxy-N-methamphetamine (MDMA) and 3,4-methylenedioxy-N-ethylamphetamine (MDEA) poisoning (n = 1), drowning in water (n = 4), cranial injuries caused by a traffic accident (n = 1) and heart failure (n = 1). In the case where the use of AMP or AMPs was considered, the immediate cause of death post-mortem toxicological analysis revealed 2 microg/ml MDMA and 0.7 microg/ml MDEA in blood. MDMA was identified in two cases of drowning (2 microg/ml in blood in the first case and 1.7 microg/g in liver in the second case) and in the traffic accident case (0.4 microg/g in liver). Methamphetamine was detected in two cases of drowning (2.5 microg/ml in blood in the first case and 6 microg/g in liver in the second case). AMP was found in the heart failure case (0.2 microg/g in liver). Alcohol was present, together with AMP or AMPs, in four cases. These findings indicate an increase in the illegal abuse of AMPs in Greece. Because of this, we now routinely screen for AMPs.     

A survey of buprenorphine related deaths in Singapore

Buprenorphine is available in Singapore as substitution treatment for opioid dependence since 2002. This study surveys buprenorphine related deaths in Singapore between September 2003 and December 2004. The aims are to establish the autopsy prevalence of buprenorphine related deaths and the demographical and toxicological profile of the cases. Toxicological screening was performed for all unnatural deaths, deaths involving known drug addicts, as well as when autopsy revealed no obvious cause of death. Twenty-one cases had buprenorphine detected in post-mortem blood and/or urine samples. Eighteen were sudden deaths. There were two fatal falls from height and one death by hanging. All subjects were male. The age range was 24-48 years. Fourteen subjects were between 30 and 39 years of age. The mean age was 35 years. The majority (62%) were Chinese. Eleven (52%) were known drug abusers. For sudden deaths, two groups were identified. Six cases died from natural causes. Blood buprenorphine levels ranged from undetected (detected in urine) to 3.2 ng/mL (mean 1.4 ng/mL). Twelve cases were attributed directly and indirectly to mixed drug poisoning. Blood buprenorphine levels ranged from undetected (detected in urine) to 17 ng/mL (mean 3.2 ng/mL). Nineteen cases showed concurrent abuse of buprenorphine and benzodiazepine, diazepam being the most frequently detected, followed by nitrazepam and midazolam. The availability of buprenorphine as substitution therapy is associated with an increase in buprenorphine related deaths. The danger of co-abuse of buprenorphine and benzodiazepines is highlighted.     

Death related to nasal surgery: case report with review of therapy-related deaths

The investigation of deaths that are suspected to be related to medical therapy present several challenges for the forensic pathologist. In all such cases, it is important for the pathologist to understand the therapy/procedure that may have played a role in death. As such, review of medical records and possible consultation with various medical specialists before autopsy can provide valuable information to ensure proper evaluation in any given case.Herein, we describe a rare death occurring as a complication of septoplasty, nasal polypectomy, and intranasal endoscopic ethmoidectomy, which are common surgical procedures performed by otolaryngology/head and neck surgeons. An otherwise healthy 58-year-old woman underwent the elective surgical procedures for a deviated nasal septum, multiple nasal polyps, and chronic ethmoid sinusitis. Following surgery, the patient never awoke from general anesthesia, and further evaluation before death revealed a basilar subarachnoid hemorrhage. Autopsy disclosed basilar subarachnoid hemorrhage, a traumatic defect of the right cribiform plate, and associated anterior cerebral artery injury with frontal lobe damage. No vascular anomalies were present. The cause of death was attributed to complications related to nasal surgery, and the manner of death was ruled "accident."Following the presentation of this case, the authors discuss these common nasal surgical procedures, including a summary of their known complications. In addition, the authors address and review the topic of deaths related to medical therapy.     

Drug and chemical related deaths: incidence in the State of Maryland--1975 to 1980

The incidence of drug and chemical related deaths was studied over a six-year period in the State of Maryland. Deaths were classified into the following categories: alcohol, carbon monoxide (CO), single drugs, multiple drugs, and narcotism. The last three categories were further subdivided as to the specific drugs or chemicals involved. Over the six-year period the number of alcohol and CO deaths remained steady, the number of barbiturate and propoxyphene deaths declined, while the number of tricyclic antidepressant drug deaths increased.     

Drug related deaths in the Strathclyde region of Scotland, 1995-1998

The misuse of drugs, both illicit and prescribed has increased dramatically in the west of Scotland over the last few decades. Consequently, the number of drug related deaths has risen as a direct result. Since, discrepancies exist between data collected by the Department of Forensic Medicine and Science, University of Glasgow and official statistics, this project, was funded to investigate all known drug related deaths that occurred within the Strathclyde region of Scotland in an effort to improve the accuracy of statistics and the dissemination of information pertaining to them. Changes in medical treatment, legislation and patterns of drug taking were noted and the effects of these on the year-by-year death tolls evaluated.     

Correlation of circumstances with pathological findings in asphyxial deaths by hanging: a prospective study of 61 cases from Seattle, WA

Correlation of the circumstances of death with the pathologic findings in this prospective study of deaths by hanging affords insight pertaining to certain of the pathophysiologic mechanisms involved in fatalities of this type. The presence of conjunctival and facial/periorbital petechial hemorrhages correlates with increasing levels of body support below the point of ligature suspension. Hyoid bone and/or thyroid cartilage fractures (found in 26% of cases) are most frequently identified in those persons found completely suspended and in victims in the older age ranges. No hyoid bone/thyroid cartilage fractures, internal soft tissue injury, or petechiae were present in 13 (21%) of the study cases.     

Defer to national circumstances or follow blindly

With respect to the current amendments to the Company Law, a balance shall be reached between the freedom and compulsion. In the current legal environment of China, it is improper for corporate legislation to adopt the authorized or eclectic capital system, and adequate amendments shall be made to the existing statutory capital system. The independent director regime conflicts with the current corporate governance structure. On the contrary, the enhancement of the legal status of the board of supervisors and the expansion of its authority are the ongoing direction in the reform of the supervisory mechanism in the corporate governance structure of China. The amendments to the Company Law shall separate the corporate legislation and the ruling of state-owned enterprises reform, hence enabling the corporate law back to the nature of private law and neutrality. The Company Law shall be amended to provide for one-person companies and eliminate wholly state-owned companies.     

Drugs and alcohol in hypothermia and hyperthermia related deaths: a retrospective study

Hypothermia and hyperthermia related cases recorded for the period 1973 to 1984 were collected from the files of the Department of Forensic Medicine, University of Oulu, and the necropsy protocols including toxicological results were analyzed. The fact that similar alcohol concentrations were found in both types of fatalities points to the poikilothermic effect of alcohol in humans, as found in animal studies. Both types of deaths seem to be associated with the alcohol elimination phase. Antidepressants and neuroleptics were most often found in the hypothermia cases, but benzodiazepines were also quite frequently present. In spite of the diminished use of barbiturates, these still appear in hypothermia fatalities. Certain other drugs that affect thermoregulation were also noted in solitary cases. Extended toxicological analysis was seldom made in the cases of hyperthermia deaths, and no firm conclusions on the poikilothermic effect of psychotropic drugs could be reached, for example. Therapeutic drug concentrations did not alone predispose the subjects to hypothermia, but appeared in connection with alcohol consumption or chronic diseases.     

Elderly deaths due to ground-level falls

This study analyzed 237 fatal ground-level falls occurring in decedents aged 65 years or older reported to the Seattle-King County Medical Examiner's Office during the year 2007. Head injuries accounted for 109 (46%) of the deaths, and nonhead injuries accounted for 128 (54%) of the deaths. Falls occurred in similar locations in both groups. Compared with those of nonhead injuries, decedents of head injuries were younger (82 vs 87.5 years), were more often male (58% vs 45%), died sooner after their injury (9 days vs 23 days), and were more likely treated with anticoagulants, especially warfarin (48% vs 16%). Subdural hematoma was the most common specific traumatic lesion, occurring in 86% of the decedents of head injury; skull fractures occurred in 13%. Decedents of head injury who were treated with anticoagulants, on average, sustained less severe head injury than those who were not treated with anticoagulants.     

Characteristic features of deaths due to decapitation

Deaths due to decapitation are rare in civilian populations. A study in South Australia over 17 years from January 1986 to December 2002 revealed 20 cases (age range, 14 to 72 years; average, 30.7 years; male to female ratio, 15:5). There were 13 suicides consisting of 11 train-related deaths (age range, 14 to 72 years; average, 31.3 years; male to female ratio, 10:1), 1 hanging death, and 1 death using a ligature and a motor vehicle. Five cases related to motor vehicle crashes (age range, 19 to 46 years; average, 30.2 years; male to female ratio, 1:4) and 2 were associated with industrial trauma. Suicidal decapitation accounted for <1% of total suicides and showed a striking male predominance, with the favored method involving trains.     

Autopsy Reenactment – A Useful Technique in the Evaluation of Adhesive Tape Asphyxia

A 19‐year‐old woman was found dead with her face and head wrapped in plastic adhesive tape in a cupboard beside an opened helium cylinder. Despite the alleged presence of a suicide message on a social networking website, the unusual circumstances raised the possibility at the time of autopsy of either accidental death from sexual asphyxia or homicide. A carefully monitored reenactment demonstrated, however, that the type of commercial adhesive tape that had been used did not cause complete airway obstruction and that it was possible to wrap a considerable length of tape around the head and neck with the breath held. All of the features at autopsy were, therefore, compatible with self‐infliction. Asphyxial death was attributed to the combined effects of smothering from tape and anoxia from helium, an extremely rare combination in young females.

Laboratory investigation of deaths due to anaphylaxis.

To establish a useful laboratory protocol to investigate possible cases of fatal anaphylaxis, we measured mast-cell-derived tryptase levels and allergen-specific immunoglobulin E (IgE) antibody levels in sera obtained prior to or within 24 h after death from 19 anaphylaxis victims. Elevated serum tryptase levels (range = 12 ng/mL to 150 micrograms/mL) were found in nine of nine Hymenoptera sting fatalities, six of eight food-induced fatalities, and two of two reactions to diagnostic therapeutic agents. Tryptase levels were normal (less than 10 ng/mL) in 57 sequential sera obtained postmortem from six control patients. Tryptase could not be measured in pleural or pericardial fluids for technical reasons. Serum IgE antibodies were elevated in five of the nine Hymenoptera sting fatalities and in eight of the eight fatal food reactions; assays were unavailable for the two diagnostic/therapeutic agents. If elevated, the victim's serum IgE antibodies to food could be used to identify allergens in uneaten portions of foods consumed shortly before the anaphylactic event. IgE antibodies were moderately stable during storage in a variety of anticoagulants at room temperature for up to 11 weeks. Elevated mast-cell-derived tryptase levels in postmortem sera reflect antemortem mast cell activation and may be used as a marker for fatal anaphylaxis. If assays are available for IgE antibodies to relevant allergens, such assays provide evidence for antemortem sensitization; these assays may be modified to identify allergens in foods consumed by victims of food-induced anaphylaxis.

Four deaths due to intravenous injection of cocaine

Cocaine is a potent psychotropic drug that alters mood and behavior by stimulating the central nervous system. Deaths from abuse of cocaine are relatively rare. Most such deaths appear to be related to the intravenous injection of the drug. Acute fatal cocaine intoxication is characterized by headache, cold sweats, rapid pulse, tremors and nausea, followed by convulsions, unconsciousness and death. The prime mode of death appears to be respiratory paralysis, secondary to the effects of cocaine on the medullary portion of the brain. This paper presents four deaths due to acute cocaine intoxication following intravenous injection. Blood concentrations of cocaine were 0.11, 0.37, 0.36 and 0.75 mg/dl.     

Sniffing-associated deaths in Denmark

An account is given of 20 deaths, which occurred in association with sniffing during the period 1959 – 1978. The annual number of deaths was almost constant during the period. Most of the deaths occurred in males. Ether and trichloroethylene were the predominant toxic substances. The material was divided into two groups. Group A, 14 cases, included real sniffing deaths, the cause of death being poisoning by the substance inhaled. In group B, 6 cases, sniffing was a contributory factor to death: 2 cases of suffocation by obstruction, one case of carbon monoxide poisoning during fire, one case of septicemia/severe anemia caused by bone marrow depression, and one case of bleeding to death from stab wounds inflicted by a sniffer against a non-sniffer. The circumstances before and at the time of death are reported, together with the autopsy and toxicological findings when these were performed.
