Recreational use of the potent synthetic opioid 3,4‐ dichloro‐N‐(2‐(dimethylamino)cyclohexyl)‐N‐methylbenzamide (U‐47700) is rising, accompanied by increasingly frequent cases of serious intoxication. This article reports a case of near‐fatal U‐47700 intoxication. A man was found unconscious (with drug powder residues). After 40 h in hospital (including 12 h of supported ventilation), he recovered and was discharged. Liquid chromatography/high‐resolution mass spectrometry (LC/HRMS) or gas chromatography/mass spectrometry (GC/MS) were used to detect and quantify substances in powders, serum and urine. Powders contained U‐47700 and two synthetic cannabinoids. Serum and urine were positive for U‐47700 (351.0 ng/mL), citalopram (<LOQ), tetrahydrocannabinol (THC: 3.3 ng/mL), midazolam (<LOQ) and a novel benzodiazepine, clonazolam (6.8 ng/mL) and their metabolites but negative for synthetic cannabinoids. If potent synthetic opioids become cheaper and more easily obtainable than their classical counterparts (e.g., heroin), they will inevitably replace them and users may be exposed to elevated risks of addiction and overdose.  相似文献

This article describes the isolation and structural elucidation of three compounds produced during the synthesis of methylamphetamine by the so‐called “Emde” procedure. The “Emde” procedure involves the preparation of the intermediate chloropseudoephedrine or chloroephedrine from ephedrine or pseudoephedrine, respectively. The intermediates are then reduced to methylamphetamine with hydrogen under pressure in the presence of a catalyst. The by‐product compounds were isolated from methylamphetamine by column chromatography and liquid chromatography (LC). Proton nuclear magnetic resonance spectroscopy (1H NMR), carbon nuclear magnetic resonance spectroscopy (13C NMR), and nanospray quadrupole‐time of flight‐mass spectrometry (Q‐TOF‐MS) were used to identify them as two stereoisomers of the compound N, N′‐dimethyl‐3,4‐diphenylhexane‐2,5‐diamine and N‐methyl‐1‐{4‐[2‐(methylamino)propyl]phenyl}‐1‐phenylpropan‐2‐amine.  相似文献

We report a case of fatal intoxication from 1,4‐butanediol (1,4‐BD), which was ingested by a young and “naïve” gamma‐hydroxybutyrate (GHB) consumer during a party with the co‐ingestion of alcohol, cannabis, and methylene‐dioxy‐methamphetamine. The following drug concentrations were found using gas chromatography coupled with mass spectrometry on autopsy samples and on a cup and a glass found at the scene: 20,350 mg/L (bottle) for 1,4‐BD; 1020 mg/L (femoral blood), 3380 mg/L (cardiac blood), 47,280 mg/L (gastric content), and 570 mg/L (vitreous humor) for GHB. The concentration of GHB is difficult to interpret in forensic cases due to the possibility of an endogenous production of GHB. The variable tolerance of the user may also modify the peri‐ and postmortem GHB concentrations. This case underscores the need to have many different sources of toxicology samples analyzed to avoid the hypothesis of endogenous production of GHB.  相似文献

This case report details an individual arrested for drug‐impaired driving after leaving the scene of multiple motor vehicle collisions and evading police. The driver was examined by a drug recognition expert and failed the drug recognition evaluation. The driver admitted to using cocaine, marijuana, an antidepressant medication and “N‐bomb,” a novel psychoactive substance that possesses hallucinogenic properties. Toxicological analyses at the Centre of Forensic Sciences’ Toronto laboratory revealed only the substance 2‐[4‐chloro‐2,5‐dimethoxyphenyl]‐N‐[(2‐methoxyphenyl)methyl]ethanamine (25C‐NBOMe) in the accused's urine. This is the first report in which 25C‐NBOMe was identified through DRE and toxicological analyses in a drug‐impaired driver.  相似文献

To circumvent the law by evading regulation and obscuring their identities in routine analyses, numerous substituted cathinones have entered the illicit drug market. These compounds have been coined “bath salts” by users. In the described case, the laboratory received an unknown white powder for controlled substances identification. The sample could not be immediately identified using standard methods and procedures. Ultimately, the structure was elucidated using GC‐MS, NMR, FTIR, GC‐SPIR, UV, and color tests to be 1‐(2,3‐dihydro‐1H‐inden‐5‐yl)‐2‐(ethylamino)pentan‐1‐one (bk‐IVP), a cathinone analog with a rarely observed nonoxygenated bicyclic ring system. Features of spectra and chemical tests are reported that distinguish this class of cathinones from heterocyclic analogs.  相似文献

Mul‐T‐Lock is a high security lock cylinder distinguished by the use of a telescoping “pin‐in‐pin”—tumbler design. Picking the Mul‐T‐Lock cylinder with a traditional picking tool is highly complicated because it can get stuck between the inner and outer pins. The H&M Mul‐T‐Lock picking tool was designed to overcome this problem and facilitate the picking of the “pin‐in‐pin” cylinder. The purpose of this research is to determine whether H&M Mul‐T‐Lock picking tool leaves class characteristic mark and whether it can be distinguished from traditional picking tools marks and from regular key marks. It also describes and determines the class characteristic mark left on telescopic pins, its origin, recurrence, and its benefit to the toolmarks examiner. When receiving a Mul‐T‐Lock from a crime scene, a toolmarks examiner can quickly determine whether or not it was picked by an H&M Mul‐T‐Lock picking tool by noticing the class characteristic mark which this typical tool leaves.  相似文献

Abstract: Ethylmorphine, an opiate that is partially metabolized to morphine, is a common ingredient in antitussive preparations. We present a case where a 10‐month‐old boy was administered ethylmorphine in the evening and found dead in bed the following morning. Postmortem toxicological analyses of heart blood by gas chromatography‐mass spectrometry and liquid chromatography‐mass spectrometry revealed the presence of ethylmorphine and morphine at concentrations of 0.17 μM (0.054 mg/L) and 0.090 μM (0.026 mg/L), respectively. CYP2D6 genotyping showed that the deceased had an extensive metabolizer genotype, signifying a “normal” capacity for metabolizing ethylmorphine to morphine. The autopsy report concluded that death was caused by a combination of opiate‐induced sedation and weakening of respiratory drive, a respiratory infection, and a sleeping position that could have impeded breathing. This is the first case report where the death of an infant has been linked to ethylmorphine ingestion.  相似文献

Children who are triangulated into their parents' conflicts can become polarized, aligning with one parent and rejecting the other. In response, courts often order families to engage mental health professionals to provide reunification interventions. This article adapts empirically established systematic desensitization and flooding procedures most commonly used to treat phobic children as possible components of a larger family systems invention designed to help the polarized child develop a healthy relationship with both parents. Strengths and weaknesses of these procedures are discussed and illustrated with case material.
    Key Points for the Family Court Community
  • Family law and psychology agree that children should have the opportunity to enjoy a healthy relationship with both parents
  • Adult conflict can polarize a child's relationships, including rejection of one parent
  • Existing clinical and forensic “reunification” strategies often prove inadequate
  • Reliable and valid cognitive behavioral methods can be adopted to facilitate this process
  • A cognitive‐behavioral “exposure‐based” reunification protocol is discussed

This article provides an in‐depth assessment of lone actor terrorists’ attack planning and preparation. A codebook of 198 variables related to different aspects of pre‐attack behavior is applied to a sample of 55 lone actor terrorists. Data were drawn from open‐source materials and complemented where possible with primary sources. Most lone actors are not highly lethal or surreptitious attackers. They are generally poor at maintaining operational security, leak their motivations and capabilities in numerous ways, and generally do so months and even years before an attack. Moreover, the “loneness” thought to define this type of terrorism is generally absent; most lone actors uphold social ties that are crucial to their adoption and maintenance of the motivation and capability to commit terrorist violence. The results offer concrete input for those working to detect and prevent this form of terrorism and argue for a re‐evaluation of the “lone actor” concept.  相似文献

The “Blue Whale Challenge” is a dangerous Internet phenomenon. As per media reports, it involves a series of life‐threatening tasks imposed by a “curator” to “players,” who must fulfill the whole list, and it ends with the suicide of the player. The authors report the data of five suspected cases of “Blue Whales” managed from January 2016 to December 2017 by the staff of a unit (the “Bambi Unit” of the Pediatric Hospital “Regina Margherita” of Turin, Italy) that is dedicated to the evaluation of suspected abused children. Then, they analyzed this data in the light of the literature regarding self‐harm. This comparison highlights the role of the Internet in the spreading of self‐harm behavior among vulnerable adolescents who are characterized by epidemiological, psychological, psychiatric, social, and cultural risk factors. In conclusion, the authors suggest a multidisciplinary and specialized approach in the evaluation of adolescents who committed self‐harm activities.  相似文献

Scholars have theorized that resource‐rich litigants known as the “haves” tend to succeed disproportionately in litigation when the adverse party is a “have‐not.” The traditional theory suggests that haves are able to use their wealth to secure better attorney representation and can use their frequent experience in litigation to tip the scales of justice in their favor, particularly when faced with “one‐shotters” whose involvement in litigation is infrequent. A remaining question, however, is whether some haves fare better than other similarly situated haves. Specifically, this article posits that the litigation strategy used by the defendant may also play a role in litigation outcomes. Companies that tenaciously fight claims that, in the short term, would be cheaper to settle might discourage otherwise valid claims in the future from being filed out of fear that the litigation will be a protracted battle. This article examines Wal‐Mart Stores, Inc. (Wal‐Mart)—the largest revenue‐generating company in the United States—to explore whether it fares better than other resource‐rich defendants. Wal‐Mart in particular has a reputation against settling cases and thus is an excellent vehicle to investigate this hypothesis. Appellate cases in an eleven‐year period involving slip‐and‐fall litigation were compiled, and the results show that Wal‐Mart did win at a higher rate than other defendants. Although more research is needed to explore fully the effect of litigation strategy on win–loss rates, this sample of cases demonstrates that Wal‐Mart is a more effective and victorious litigant.  相似文献

Little is known of the postmortem distribution of ?9‐tetrahydrocannabinol (THC) and its major metabolite, 11‐nor‐9‐carboxy‐?9‐tetrahydrocannabinol (THCCOOH). Data from 55 pilots involved in fatal aviation accidents are presented in this study. Gas chromatography/mass spectrometry analysis obtained mean THC concentrations in blood from multiple sites, liver, lung, and kidney of 15.6 ng/mL, 92.4 ng/g, 766.0 ng/g, 44.1 ng/g and mean THCCOOH concentrations of 35.9 ng/mL, 322.4 ng/g, 42.6 ng/g, 138.5 ng/g, respectively. Heart THC concentrations (two cases) were 184.4 and 759.3 ng/g, and corresponding THCCOOH measured 11.0 and 95.9 ng/g, respectively. Muscle concentrations for THC (two cases) were 16.6 and 2.5 ng/g; corresponding THCCOOH, “confirmed positive” and 1.4 ng/g. The only brain tested in this study showed no THC detected and 2.9 ng/g THCCOOH, low concentrations that correlated with low values in other specimens from this case. This research emphasizes the need for postmortem cannabinoid testing and demonstrates the usefulness of a number of tissues, most notably lung, for these analyses.  相似文献

On the morning of December 17, 1827, nine convicts were executed by public hanging in Hobart Town, the capital of the British colony of Van Diemen's Land (now the Australian state of Tasmania). Two months previously they had drowned senior Constable George Rex on Small Island, which was part of the penal settlement at Macquarie Harbor, in front of five bound and gagged witnesses. They offered no defence at their trial. Examination of the Tasmanian colonial convict records shows that “suicide by lottery” involved convicts choosing two men, one to die and the other to kill him. The witnesses would earn a respite when taken away for the trial, and the murderer would be executed. “Death by gallows” could be considered a nineteenth‐century version of an orchestrated suicide reminiscent of more modern “death by cop.” This category of “judicial” murder‐suicide expands the range of contemporary classifications of dyadic deaths.  相似文献

Regulators in a number of countries are increasingly developing “risk‐based” strategies to manage their resources, and their reputations as “risk‐based regulators” have become much lauded by regulatory reformers. This widespread endorsement of risk‐based regulation, together with the experience of regulatory failure, prompts us to consider how risk‐based regulators can attune the logics of risk analyses to the complex problems and the dynamics of regulation in practice. We argue, first, that regulators have to regulate in a way that is responsive to five elements: (1) regulated firms' behavior, attitude, and culture; (2) regulation's institutional environments; (3) interactions of regulatory controls; (4) regulatory performance; and (5) change. Secondly, we argue that the challenges of regulation to which regulators have to respond vary across the different regulatory tasks of detection, response development, enforcement, assessment, and modification. Using the “really responsive” framework, we highlight some of the strengths and limitations of using risk‐based regulation to manage risk and uncertainty within the constraints that flow from practical circumstances and, indeed, from the framework of risk‐based regulation itself. The need for a revised, more nuanced conception of risk‐based regulation is stressed.  相似文献

A 20‐year‐old man, a cocaine addict and regular ecstasy user, with a medical history of allergic asthma died after ingesting half a tablet earlier the same day. The white tablet, stamped with a “smiling sun” logo looked very much like an ecstasy tablet and was sold as such. He experienced a severe asthma attack just after ingesting the half tablet and it evolved over the next few hours into fatal cardiorespiratory arrest. Biological samples, taken after embalming, were analyzed by high‐performance liquid chromatography tandem mass spectrometry (HPLC‐MS/MS). Analysis revealed meta‐chlorophenylpiperazine (mCPP) in concentrations of 45.8 mg in a similar tablet obtained later from the drug dealer, 5.1 ng/mL in the bile, 0.3 ng/g in the liver, 15.0 ng/mL in the urine, and its absence in a hair sample (<0.02 ng/mg), which indicated he was not a regular user (whereas strong concentrations of MDMA and cocaine were found in the hair). Interrogated by the police after his arrest, the dealer said that he had sold the victim and for the very first time two tablets with the same “smiling sun” logo. The tablet used for analysis was from the same brand as the one ingested by the victim. The autopsy excluded other causes of death, while the histological analyses showed a large number of polynuclear eosinophils in the bronchial walls, confirming the asthmatic pathology. None of the other organs examined (larynx, liver, heart, adrenal glands, and kidneys) showed any distinctive signs, and in particular no inflammatory infiltrate. The death was the result of an asthma attack in an asthmatic person, violently decompensated following ingestion of approximately 20 mg of mCPP.  相似文献

We have carried out experiments to investigate the aging of latent fingerprints deposited on black PVC over a period of 4–15 weeks. A thumbprint was used in each case and before deposition of the print the donor rubbed their thumb around their nose to add sebaceous deposits. We have studied the effect of heat, light, and moisture and we find that moisture is the most significant factor in the degradation of the latent print. We have attempted to enhance these latent prints by dusting with valine powder or powders composed of valine mixed with gold or red fluorescent commercial fingerprint powders. To make a direct comparison between “treated” and “untreated” prints, the prints were cut in half with one‐half being “treated” and one‐half not. Our studies show the best results being obtained when powders of valine and red fluorescent powders are applied prior to cyanoacrylate fuming.  相似文献

CP 47,497, a potent cannabinoid receptor type 1 agonist, is the main active ingredient in the herbal mixture “Spice” sold in European countries. The illegal use of “Spice” for its psychoactive effects has become a social issue. In this study, the in vitro metabolism of CP 47,497 was investigated in human liver microsomes to characterize the metabolic fate of CP 47,497. CP 47,497 was incubated with human liver microsomes, and the reaction mixture was analyzed using liquid chromatography‐tandem mass spectrometry. A total of eight metabolites were detected in human liver microsomes and structurally characterized based on mass spectral data. The main metabolic pathways involved hydroxylations or oxygenations. The identified metabolites were mono‐oxygenated metabolites (M1 and M4), mono‐hydroxylated metabolites (M3, M5, M6, M7, and M8), and a di‐oxygenated metabolite (M2). The detection of these metabolites could confirm the presence of CP 47,497 in biological samples; therefore, collectively, they would be excellent indicators of “Spice” drug abuse.  相似文献

The COVID‐19 pandemic has had, and continues to have, a broad, deep, and pervasive impact on our lives, our work, and how our justice system functions. While it is easy to contemplate the “system” as a massive behemoth that is impervious, impersonal, and impenetrable, the truth is that the “system” is made up of people. The men and women whose work is the building blocks of the justice system are individuals, each with their own narrative, experience, perspective, and role in the administration of justice. To understand the system and the impact of COVID‐19, it is essential to understand the stories of those who work in the system. This article presents the individual and human stories of four professionals whose professional lives are a part of the justice system. Each of these professionals tells their personal story of COVID‐19 and reflects on how the pandemic affected them and their approach to the work that they do.  相似文献

Medium‐chain acyl‐CoA dehydrogenase (MCAD) deficiency is a rare but important component of the differential diagnosis for adults with a history of premortem mental status changes and the postmortem finding of hepatic steatosis. This case report describes a 30‐year‐old white man who, following a period of nausea and vomiting, was admitted to the hospital with sudden mental status deterioration followed rapidly by clinical deterioration and death. Treating physicians in this case suspected acute illicit drug toxicity with synthetic cathinones based on social history. Clinicians and medical examiners should be aware that the presentation, signs, and symptoms described may indicate an underlying inborn error of metabolism such as MCAD deficiency and take action accordingly.  相似文献

This paper explores the ways in which male offenders in professional‐status occupations prior to conviction construct and justify money‐related crime. We report a detailed analysis, based in grounded theory and critical social‐psychological discourse analysis, of a loosely‐structured group interview with four offenders. The men constructed justifications for their offenses in terms of “breadwinning” for their immediate family and economic responsibility toward their extended “family” of employees and creditors. They represented their post‐conviction decline in social status as being “dragged down” by envious “boys” in the state apparatus. They positioned themselves on moral high ground, despite having been inappropriately sent to the working class world of prison (“Dante's Inferno”). We contrast these accounts with those of less privileged male offenders.  相似文献
