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.     

Flunitrazepam: psychomotor impairment, agitation and paradoxical reactions

Benzodiazepines are sedatives used for anxiolysis, hypnosis, muscle relaxation and the treatment of epilepsy. Paradoxical reactions including agitation, talkativeness, confusion, disinhibition, aggression, violent behavior and loss of impulse control may, however, occur in some subjects. It has been claimed that high doses of flunitrazepam may cause aggression on a more regular basis in all individuals. The present study makes use of a Norwegian forensic toxicological database containing analytical results from drivers suspected of driving under the influence and suspects of violent crime to analyze the relationship between behavior and blood flunitrazepam concentration. Four-hundred and fifteen cases of drivers suspected of driving under the influence and seven cases of suspects of violent crime were studied. These selected cases had flunitrazepam as the only drug in blood samples and had been evaluated by a clinical test for impairment (CTI) performed by a police physician at the time of blood sampling. The impaired drivers had higher blood flunitrazepam concentrations than the not impaired drivers. Multivariate analysis revealed that both blood flunitrazepam concentration and age of the suspected drivers had independent impact on impairment, indicating tolerance with age. Most of the effects measured were sedative effects of flunitrazepam and these effects were related to flunitrazepam level. Possible paradoxical reactions were observed in a subgroup of 23 individuals (6%), but these reactions did not relate to blood flunitrazepam concentration. The suspects of violent crime showed similar degree impairment and had not more paradoxical reactions than the suspected drugged drivers. The findings were in agreement with other research that claims paradoxical reactions should be viewed as a reaction in certain individuals, and does not support the notion that flunitrazepam in high concentration produces aggression in all individuals taking the drug.     

Neoplastic disease in a medicolegal autopsy material. A retrospective study in northern Sweden

Only a small fraction of sudden unexpected deaths are caused by neoplastic disease and thus subject ot medicolegal autopsy. The medicolegal autopsy forms an opportunity to study not only medically diagnosed and treated neoplasms, but also the natural evolution of untreated disease. In a series of 7,020 consecutive medicolegal autopsies in northern Sweden, we found 171 cases with malignant and/or intracranial neoplasms. In 41 cases, sudden death was caused by previously unknown tumors. The most common mechanisms of death in this group were disseminated cancer, intracranial tumors, pulmonary thromboembolism, hemoptysis, and aspiration of blood, and the most common locations were the bronchi and the lung. In some of these cases, the mechanism was sometimes dramatic, raising a question of violent death or intoxication. In 30 cases, sudden unexpected death was caused by previously known tumors, and also in this group disseminated cancer was the most common cause of death, and the most common locations were the bronchi and the lung. In 22 cases, tumors were found suicidal cases; in 14 of these, the tumor was considered to be a major causative factor to the suicide, while in eight cases the tumor was considered to be an incidental finding. The expected number of cancers in the 1,060 suicides investigated in this series was 27, according to the official cancer prevalence data. Thus, a possible over-representation of suicides among persons with cancer seems doubtful and needs further exploration.     

Anabolic androgenic steroids in police cases in Sweden 1999-2009

Anabolic Androgenic Steroids (AAS) are considered drugs of abuse and are controlled substances in Sweden since 1999. Traditionally AAS have been used by elite athletes to enhance performance, but in recent years it has become an increasing problem outside elite sport among athletes, bodybuilders and criminals. Use of AAS is associated with psychiatric side effects such as aggression, depression and violent behavior. Supraphysiological doses and long term use can cause serious physical harm such as cardiovascular toxicity and even premature death. We investigated and evaluated the drug analytical findings in forensic cases from suspected perpetrators in cases from the police where a screening for AAS was requested to get information about the prevalence of AAS use and the occurrence of poly-drug abuse. The study was based on samples submitted from the police authorities to the Department of Forensic Toxicology in Sweden during the period 1999-2009. Urines were analyzed by methods based on GC-MS and LC-MS-MS. We also analyzed the prevalence of AAS use at the prison and probation services. A total number of 12,141 urine samples (6362 police cases and 5779 inmates) were analyzed and 33.5% of the cases from the police and 11.5% of the inmates were tested positive for AAS. The users of AAS were mainly in 99.2% men with a mean age of 26.2±6.2 years whereas the women were 29.5±6.5 years old. The most frequently used AAS was nandrolone followed by testosterone and methandienone. Other illicit and licit drugs were detected in 60% of the cases from the police, strongly indicating a frequent poly-drug abuse among users of AAS.     

Cause of death and drug use pattern in deceased drug addicts in Sweden, 2002-2003

Compared with their contemporaries, individuals abusing illicit drugs suffer a higher risk of premature death. In Sweden, a simple protocol for registration of fatalities among abusers of alcohol, pharmaceuticals, illicit drugs, or other substances, has been used by the forensic pathologists since 2001. This routine was introduced to allow for an evaluation of the cause and manner of death, and patterns of abuse among different groups of abusers. We explored the data on drug abusers (i.e. abusers of illicit drugs) subjected to a forensic autopsy 2002-2003. The Swedish forensic pathologists examined 10,273 dead victims during the study period and 7% (743/10,273) of the cases were classified as drug abusers. Toxicological analyses were carried out in 99% (736/743) and illicit drugs were detected in 70% (514/736) of these. On average, 3.8 substances (legal or illegal) were found per case. The most common substances were ethanol and morphine, detected in 43 and 35% of the cases, respectively. When exploring the importance of the different substances for the cause of death, we found that the detection of some substances, such as fentanyl and morphine, strongly indicated a poisoning, whereas certain other substances, such as benzodiazepines more often were incidental findings. In total, 50% (372/743) died of poisoning, whereas only 22% (161/743) died of natural causes. Death was considered to be directly or indirectly due to drug abuse in 47% (346/743), whereas evidence of drug abuse was an incidental finding in 21% (153/743) or based on case history alone in 33% (244/743). We believe that this strategy to prospectively categorize deaths among drug addicts constitutes a simple means of standardizing the surveillance of the death toll among drug addicts that could allow for comparisons over time and between countries.     

Fatal poisoning in drug addicts in the Nordic countries.

The study includes medicolegally examined fatal poisonings among drug addicts in 1997 in the five Nordic countries: Denmark, Finland, Iceland, Norway and Sweden, and the results are compared to a similar investigation from 1991. A common definition of "drug addict" was applied by the participating countries.The highest death rate by poisoning in drug addicts was observed in Denmark, where it was 6.54 per 10(5)inhabitants, followed by Norway with 6.35, Sweden with 2.21, Finland with 1.63 and Iceland with 1.20 per 10(5)inhabitants. All countries showed a higher death rate in 1997 than in 1991. For all countries the distribution of deaths according to geographical regions showed a decreasing number of drug deaths in the metropolitan area and an increasing number in other cities. Heroin/morphine dominated as the cause of death and was responsible for about 90% of the cases in Norway. In Sweden and Denmark, however, heroin/morphine caused only about 70% of the fatal poisonings. About 30% of the fatal poisonings in Denmark and Sweden were caused by other group I drugs, in Denmark mainly methadone and in Sweden mainly propoxyphene. Apart from two cases in Sweden methadone deaths were not seen in the other Nordic countries. In Finland heroin/morphine deaths have increased from about 10% in 1991 to about 40% in 1997. Forty-four percent of the fatal poisonings in Finland were caused by other group I drugs, mainly codeine and propoxyphene. The two fatal poisonings in Iceland were caused by carbon monoxide. Only few deaths in this investigation were caused by amphetamine and cocaine. A widespread use of alcohol, cannabis and benzodiazepines, especially diazepam, was seen in all the countries.     

Drugged driving in the Nordic countries--a comparative study between five countries

The purpose of this study was to compare whether the high incidence of drugged driving in Norway was different to that in the other Nordic countries. All blood samples received by Nordic forensic institutes during one week in 1996, from drivers suspected by the police of driving under the influence (Denmark: n = 255, Finland: n = 270, Iceland: n = 40, Sweden: n = 86, Norway: n = 149), were analysed for alcohol and drugs (benzodiazepines, cannabinoids, amphetamines, cocaine, opiates and a number of antidepressant drugs) independent of the primary suspicion, and using the same analytical cut-off levels at the different institutes. The primary suspicion was directed towards drugs in more than 40% of the Norwegian cases, drugs were detected in more than 70% of these samples. In only 0-3% of the cases from Denmark, Finland and Iceland, were drugs suspected, while the corresponding frequency for Sweden was 17%. However, evidential breath analyses were used for about three-quarters of the Swedish drivers suspected to be influenced by alcohol. Blood alcohol concentrations (BAC's) below the legal limits were found in 32, 18 and 2% of the Norwegian, Icelandic and Finnish cases, respectively (BAC < 0.05%), in 10% of the Danish cases (BAC < 0.08%) and in 20% of the Swedish cases (BAC < 0.02%). Drugs were most frequently found in the Norwegian and Swedish cases with no alcohol (80-83%). Similar frequencies of drugs in samples with BAC's above the legal limits (19-22%), were obtained for all countries. Benzodiazepines, tetrahydrocannabinol and amphetamine represented the most commonly detected drugs. Our results show that differences between Norway and other Nordic countries with regard to drugs and driving, are connected to the selection criteria made by the police and with more focus on drugged driving in Norway.     

Abuse and neglect: a ten-year review of mortality and morbidity in our elders in a large metropolitan area

Elder abuse and neglect refers to an act or omission resulting in harm, including death, or threatened harm to the health or welfare of an elderly person. Between one and two million elderly Americans experience some form of mistreatment annually. A ten-year (1992-2001) retrospective case review of morbidity and mortality among elders (age > 60 years) was conducted at a State Medical Examiner's Office serving a major metropolitan region in Kentucky and Indiana. This study addresses cases of two categories: 1) medicolegal autopsies and 2) examinations of living subjects pursuant to a Clinical Forensic Medicine Program. The authors present 74 postmortem cases, in which 52 deaths were attributed to a homicidal act and 22 deaths were suspicious for neglect. Of the 22 living victims of elder abuse and neglect, 19 cases constituted physical and/or sexual assault and three individuals suffered from neglect. This study summarizes the characteristic features of elder abuse in both postmortem and living cases and underscores the necessity for multi-agency collaboration in order to reach an accurate conclusion in case work. Policies established by a well-established elder abuse task force promote the collaborative interaction necessary to formulate criteria for prevention of abuse and death within this vulnerable population.     

Explanations for violent behaviour—An interview study among forensic in-patients

The alleged relation between mental disorder and violent criminal behaviour has been investigated mainly from an epidemiological perspective. Population-based registry studies have shown that violence occurs more frequently among people with mental disorders, like schizophrenia and bipolar disorder, compared with control subjects, but that the increased risk is largely mediated by drug abuse and socio-economic deprivation. The aim of this study was to explore how patients who have committed violent or sexual crimes and have been sentenced to forensic psychiatric care by a Swedish court of law construed their criminal actions in terms of causes. Forty-six participants from six different Swedish forensic psychiatric clinics were included in the study. A semi-structured interview study was conducted and the data was analysed using a thematic analysis. A large group of the participants did not believe that the mental disorder played any role in the criminal events. Contributing causes that were mentioned were drug abuse and social factors.     

Investigation of drug-related deaths. An overview

Drug-related deaths encompass fatal overdoses, the medical derangements from chronic consumption, and violent death from the alteration of normal behavioral patterns. Determining the extent to which a drug contributed to a death necessitates correlation of all aspects of the death investigation; autopsy and toxicologic findings must be interpreted in the light of antecedent events, medical and social history, and thorough scene investigation. The approach to the medicolegal investigation of drug-related deaths is discussed along with some legal ramifications and certain potential problems of death certification.     

Nutmeg (myristicin) poisoning--report on a fatal case and a series of cases recorded by a poison information centre

In literature, cases of nutmeg abuse have been described repeatedly, but only one fatal case of poisoning was reported [1]. In the present case, myristicin (4 microg/ml) was detected for the first time in the postmortal serum of a 55-year-old woman. Identification was achieved with the aid of UV-VIS spectroscopy and TLC; for quantification, HPLC was used. Because also flunitrazepam (0.072 microg/ml) was found, death had probably been due to the combined toxic effect of both substances. From 1996 to 1998, in a series of cases, seven poisonings with nutmeg were recorded by the Erfurt Poison Information Centre. Even where higher doses (20-80 g of powder) had been ingested, a life-threatening situation was never observed. In one of these cases, a myristicin blood level of 2 microg/ml was measured 8h after ingestion of two to three tablespoonful of nutmeg powder (approx. 14-21 g, or 280-420 mg/kg).     

Uncertainty of determining mode of death in medicolegal material without autopsy — A systematic autopsy study

Systematic autopsy was performed in 807 medicolegal deaths where the police had not requested autopsy. In all cases both the cause of death and the mode of death had been reported at the medicolegal external examination. The autopsy revealed differences in the mode of death in about 4% of all cases. This was due in particular to the problems associated with distinguishing presumed natural deaths from accidents and suicide. The cases of “concealed” suicide were found in particular among the higher age groups. However, no characteristic relationship was found between the proportion of differing modes of death and the age groups. All cases of homicide were recognized at the medicolegal external examination.Malignant disease that had not been diagnosed previously was found in about 4% of the cases, the reason being the large proportion of elderly subjects in the material. Syphilitic aortitis that had not been previously diagnosed was demonstrated in about 1% of all cases, and pulmonary tuberculosis that had not been previously diagnosed was demonstrated in 0.7% of the cases.The conclusion is that the results provide no support for replacing the medicolegal autopsy by medicolegal external examination alone, but rather suggest that the proportion of medicolegal autopsies should be increased.     

The interfaces of law and medicine.

The relationship between the legal and medical professions is improving, but many problems remain. There has been been and continues to be substantial growth in medicolegal organizations of various kinds. Better medicolegal investigative methods are being developed, and medicolegal teaching programs are on the increase. The two professions have worked together successfully on such problems as human heart transplantation and drug abuse. On the other hand, several problem areas continue to cause difficulty and friction, including medical experimentation on humans, the legal definition of death, abortion, euthanasia, and medical malpractice. The author calls on the existing medicolegal organizations to apply their expertise and influence to define and resolve these problems.     

Fatal amphetamine-associated cardiotoxicity and its medicolegal implications

Amphetamines are popular drugs of abuse, particularly among youngsters and at dance scenes. Cardiotoxicity (manifested as cardiomyopathy, acute myocardial infarction/necrosis, heart failure, or arrhythmia) after the recreational (mis)use of amphetamine and its synthetic derivatives has been documented but is rather rare. Amphetamine-related cardiac fatalities are even more rare. We present 6 cases of young persons who died unexpected after the chronic abuse of amphetamines. Death was not attributed to a lethal intoxication but to an acute myocardial necrosis, a right ventricle rupture, a cardiomyopathy, or an arrhythmia. Two of the deceased persons presented prior to their death to the emergency department, but their complaints were not considered (probably due to their young age) to be of cardiac origin. One case was a sport-related fatality where medical screening failed to identify the underlying cardiac pathology or the amphetamine abuse, and 1 case was a so-called idiopathic dilated cardiomyopathy where substance abuse was not considered by the treating physician. We think that amphetamine-associated cardiotoxicity is a rare but probably genuine entity that should be considered both in forensic and clinical/emergency medicine because of its potential medicolegal implications.     

A validated method for the analysis of cannabinoids in post-mortem blood using liquid-liquid extraction and two-dimensional gas chromatography-mass spectrometry

Phenazepam is a long-acting benzodiazepine that, unlike other benzodiazepines, is currently not scheduled as a narcotic in Finland, most other European countries or the USA. It is used as an anxiolytic, sedative-hypnotic and anti-epileptic, mainly in Russia. In Finland, as well as in some other countries, an increase in the unauthorized use of phenazepam has been observed in recent years. In the one year period between July 1, 2010 and June 30, 2011 the prevalence of phenazepam in Finland was assessed among drivers apprehended for driving under the influence of drugs (DUID), in medico-legal autopsy cases and in police confiscations of illicit drugs. In DUID cases an LC-MS/MS method preceded by solid phase extraction was used for the determination of phenazepam. In the post-mortem investigations the sample preparation consisted of liquid-liquid extraction followed by derivatization and the determination was carried out by GC-MS. The police confiscations were analysed by GC-MS. There were 141 positive phenazepam cases among apprehended drivers, representing approximately 3.5% of all confirmed drug cases (n=4007) in this time period. The median (range) phenazepam blood concentration in DUID cases was 0.061 mg/L (0.004-3.600 mg/L). The median phenazepam concentration in cases with no concomitant stimulant use was significantly higher than the overall median concentration. Phenazepam was found in 17 medico-legal autopsy cases and the median (range) blood concentration was 0.048 mg/L (0.007-1.600 mg/L). Phenazepam was not considered by the medico-legal team to be the sole cause of death in any of the cases, the majority of them being accidental opiod overdoses. There were 26 seizures of phenazepam by the Police in the time period studied, some of the batches consisted of a mixture of phenazepam and stimulant designer drugs. The data show that phenazepam abuse is a widespread phenomenon in Finland. A typical user was a male multi-drug user in his 30s. The concentration range of phenazepam among apprehended drivers and medico-legal autopsy cases was wide and the drug was usually found along with other psychoactive drugs. Therefore, although it seems likely that phenazepam contributed to impairment of driving in some DUID cases, the extent of its effect remains unclear and further studies are needed to define the concentrations causing impairment and toxicity.
