Ebstein Anomaly and Sudden Childhood Death

A 13‐year‐old girl is reported who died suddenly and unexpectedly in her sleep from previously undiagnosed Ebstein anomaly. At autopsy, there was dilatation of the right atrium with marked dilatation of the right auricle and apical displacement of the tricuspid valve into the right ventricular cavity with atrialization of the upper portion of the right ventricle. There were also prominent dysplastic changes in both the septal and posterior leaflets of the tricuspid valve with thickening of the valve and fusion of leaflets to the wall of the ventricle. Histology of the myocardium showed focal, minor microscopic areas of interstitial fibrosis with marked fibrous dysplasia and thickening of the tricuspid valve. Lethal arrhythmias occur in this condition because of the geographical relationship of the conduction system to the abnormal anatomical structures. As adolescents who died suddenly are often minimally symptomatic, cases will rarely present de novo to forensic autopsy.     

Reproductive Health: Morals,Margins and Rights

Reproductive interventions and technologies have the capacity to generate profound societal unease and to provoke hostile reactions underpinned by various moral concerns. This paper shows that this position currently goes relatively unchecked by the European Court of Human Rights, which allows the margin of appreciation and consensus doctrines significantly to limit the scope of reproductive rights under the right to respect for private and family life under Article 8. This occurs both in relation to the interest in avoiding reproduction at stake in abortion, and that in achieving it at stake in medically assisted reproduction. The paper demonstrates significant flaws in the Court's framing and deployment of these doctrines in its reproductive jurisprudence. It argues that, as regards existing and upcoming reproductive interventions and technologies, the Court should attend to the concept of reproductive health, long recognised in international conventions and policy materials.

Involvement of Amphetamines in Sudden and Unexpected Death

Abstract:  In the present study, the effects of amphetamine-class drugs were examined in cases reported to the Victorian coroner from 2001 to 2005 to determine if death can occur from the use of amphetamine-class drugs alone. A total of 169 cases were reviewed where a forensic autopsy detected amphetamine(s) in the blood. Pathology, toxicology, and police reports were analyzed in all cases to ascertain the involvement of amphetamine-class drugs in these deaths. In Victoria, methamphetamine (MA) is the principal abused amphetamine-class followed by methylenedioxymethamphetamine (MDMA). There were six cases in which a cerebral hemorrhage caused death and three cases in which serotonin syndrome was established as being caused by the interaction of MDMA and moclobemide. There were 19 cases in which long-term use of amphetamines was associated with heart disease. There were three cases where amphetamine-class drugs alone were regarded as the cause of death, of which two cases exhibited high levels of MDMA and lesser amounts of MA and/or amphetamine. There were no cases in which significant natural disease was absent and death was regarded as caused by the use of MA. There was no correlation between blood concentration of drug and outcome.     

连接蛋白43与心性猝死的相关性研究进展

部分心性猝死者死后尸检时心脏没有发现明显病理学异常征象,过去均将其归属原因不明的猝死范畴。近年来研究显示,心肌连接蛋白43（connexin43,Cx43）表达对于心性猝死的诊断具有十分重要的意义。本文就Cx43结构、功能以及在心血管疾病发生发展中的作用与法医学意义作一综述。     

African biomedical scientists and the promises of “big science”

Abstract

An ongoing genomic revolution in biology has exponentially increased the rate, possibilities, scope and cost of biological research. Infectious disease genomics are often justified by the potential they have to ameliorate Africa’s disease burden. The molecular biology revolution that preceded genomic science widened the gap between the skill sets of many African biologists and their contemporaries elsewhere. Gap closure through genomics and the application of genomic data to health problems requires participation of, and leadership from, African scientists. However, few African scientists participate in genomics, and providing biological samples is their predominant contribution. Health-related applications are emerging from genomic activity for some infectious diseases that are endemic in Africa but not for many others. This article argues that the arrival of next-generation diagnostics, surveillance tools, drugs and vaccines could be accelerated by improving the nature and degree of participation of African scientists in genomic and post-genomic inquiry.
