Multiple deaths resulting from shipboard exposure to trichlorotrifluoroethane

During the course of dockside ship maintenance, a compartment was partially flooded with tricholotrifluoroethane gas. One sailor entered the compartment, collapsed, and was then rescued by two other men. All three victims then climbed a 11-m (36-ft) ladder and collapsed. They all experienced a rapid development of cardiac arrest. We report on the pathologic, toxicologic, and pathophysiologic aspects of the incident.     

Liberty: human rights and mental health

In this paper, Lord Phillips reflects on the present state of the law relating to mental health; he considers the place of the common law doctrine of necessity as the basis for the detention of patients; he reviews a number of issues arising from the jurisprudence of the European Court of Human Rights in Strasbourg and a number of recent decisions of the Court of Appeal. Finally, he considers the prospects for change in the law foreshadowed in the Government's White Paper on the Reform of Mental Health Law (2000).     

Mitochondrial DNA sequencing of beetle larvae (Nitidulidae: Omosita) recovered from human bone

The isolation, amplification, and characterization of human DNA from hematophagous (blood feeding) and necrophagous (carrion feeding) arthropods have been advanced significantly by the development of polymerase chain reaction (PCR) DNA sequencing methodologies. Historically, DNA technology has been successfully utilized to identify individual hosts upon which species of hematophagous arthropods have fed. The analysis of hematophagous insects' gut content blood meals has led to major advances in medical entomology and vector-borne disease epidemiology. In the forensic arena, the ability to apply similar techniques to insects recovered from badly decomposed remains has been greatly enhanced through the advent of mitochondrial DNA (mtDNA) techniques. Mitochondrial DNA analyses have been utilized to identify both the human remains upon which fly larvae (maggots) have fed and the species of the larvae themselves. The preliminary work detailed here demonstrates, for the first time, the successful application of mtDNA sequencing techniques to the analysis of necrophagous beetle larvae. A small sample of sap beetle larvae, Omosita spp. (Coleoptera: Nitidulidae), was collected from human skeletal remains during anthropological examination and analyzed for human DNA using mtDNA sequencing. The beetle larvae yielded mtDNA matching that of the host human bone. The results detailed here further demonstrate the robust nature of human mtDNA and the ability to recover valuable mtDNA evidence from forensically important, late decompositional stage insect species.     

Integrating risk,the Good Lives Model and recovery for mentally disordered sexual offenders

Abstract

Personality disordered and mentally disordered sexual offenders (MDSOs) with complex diagnoses such as schizophrenia, developmental disorders and mood disorders face challenges of restoring their mental health, living more safely with personality- and offence-related risks, while addressing concerns about their capacity to reintegrate into society; this has been termed “secure recovery”. This paper reviews the literature on recovery, demonstrating its commonality with the Good Lives Model (GLM) as applied to MDSOs' offending treatment. GLM appears to provide a better fit with the recovery needs of MDSOs than the Risk–Need–Responsivity model because it emphasises approach goals, enhanced responsivity and skills acquisition. Recovery needs to integrate coping with mental disorders with risk management and a healthy, future lifestyle. Both secure recovery and GLM support the need for client–clinician collaboration, promoting self-determination and a shared narrative about coping with enduring risk and the hope of sustained well-being.     

Insect larvae used to detect cocaine poisoning in a decomposed body.

Insect larvae are often found on human remains long after disappearance of the usual toxicologic specimens. It is important for forensic pathologists and toxicologists to recognize the potential of this unique specimen when routine specimens are not available. Cocaine and benzoylecgonine was extracted from Calliphorid larvae found on a badly decomposed body of a man who had been missing 5 months and was also identified in the decomposing skeletal muscle. This toxicologic information combined with the autopsy findings and the circumstances of the death and disappearance was essential in the determination of cocaine poisoning as the cause of death.
