The successive killing of three siblings by their biological mother at two-year intervals is described. The children were 367 days, 75 days and 3 years old. Although sudden infant death syndrome (SIDS) or interstitial pneumonia could not be ruled out as the cause of death in the two younger children, who were killed first, the third child exhibited discrete signs of violence in the mouth and throat area which were interpreted as proof of infanticide. All three children had petechiae of the skin of the face and throat, the upper thorax, the shoulders and the mucous membranes of the mouth. None of the children exhibited signs of a disease-related hemorrhagic tendency. After the mother was convicted of murdering the three-year-old boy by smothering in combination with compression of the thorax, she confessed to having killed the other two children in a similar manner. In the absence of hemostatic disease, the presence of petechiae of the skin extending over the entire drainage area of the Vena cava superior can be regarded as evidence of an increase in pressure in the thoracic cavity secondary to obstruction of the airways with simultaneous chest compression. 相似文献

In this Article, Professor Carlos A. Ball explores the philosophical foundations for the types of rights and benefits that our society currently provides to individuals with disabilities. The concept of autonomy places on society a moral obligation to assist individuals with disabilities when their basic human functional capabilities are impaired. The exercise of this obligation entails assisting individuals with crossing a minimum threshold of functional capabilities below which it is not possible to lead autonomous lives. In making this argument, Professor Ball responds to libertarian critics who contend that notions of freedom or liberty proscribe an activist role for government in this arena. He explains how even a libertarian state redistributes wealth in order to provide for some incapacities. Professor Ball also disputes the idea that the meeting of the needs of the disabled is enough to provide moral justification for the rights and benefits provided to individuals with disabilities. The problem with the concept of needs, Professor Ball argues, is that it fails to account sufficiently for the human good of personal autonomy. 相似文献

Oregon's Death with Dignity Act was first passed by a ballot initiative in 1994, but numerous judicial challenges delayed implementation of the Act. In November of 1997, following the United States Supreme Court decisions in Vacco v. Quill and Washington v. Glucksberg, which left the states' power to regulate physician-assisted suicide undisturbed, the Oregon voters upheld their law. Oregon remains the only state in the nation to authorize physician-assisted suicide. The Task Force to Improve the Care of Terminally Ill Oregonians published a Guidebook for health care providers on the Oregon Act, and the New England Journal of Medicine recently issued a special report on the first year's experience under the Act. This paper analyzes the legal context of the Oregon Death with Dignity Act, discusses the efficacy of the tenets in the Guidebook, and explores ethical issues underlying the guidelines, particularly those pertaining to the meaning of a patient's request for assisted suicide and processes supporting informed consent. 相似文献

This article discusses the desirability of legislation focusing on genetic discrimination, in particular in the context of insurance. Many American states and some European countries as well as the Council of Europe have introduced protective measures against discrimination on the basis of genetic susceptibility. The author questions their effectiveness and queries whether they may be inequitable, because they fail to address more fundamental underlying issues related to the nature of insurance, access to health care, and unequal distribution of wealth. There is also a problem of definition in these statutes. They fail to capture what constitutes genetic information. Nonetheless, the author argues it is important to consider the social consequences of genetic testing. Michael Walzer's theory of justice is used to examine the role of insurance and health care. Using this approach, the author finds the American system of distribution for health care to be problematic. This is then used to inform the author's discussion of the future of health care in Canada. Anti-discrimination provisions could be used in a way that is consistent with Walzer's theory of justice. They would encompass both genetic and non-genetic health factors. These can be modelled on current anti-discrimination statutes in Canada. The author then proposes administrative committee structures to regulate the use of genetic data in Canada. 相似文献

Advances in the diagnosis of wound vitality: a review 总被引:2,自引:0,他引:2

The diagnosis of the vital origin of wounds in many cases remains an unsolved problem for the forensic pathologist. Practical experience enables the expert to diagnose the vital or postmortem origin of wounds on the basis of macroscopic examination. In some cases, optic microscopy is used to confirm the diagnosis. In many other cases, additional more sensitive and specific markers of vitality are required. In the past 50 years, comprehensive research on this topic has resulted in a better understanding of the acute inflammatory reaction. The development and application of sensitive and specific markers through research in the areas of histochemistry, enzymology, and biochemistry has provided a partial solution to the problems involved in wound vitality diagnosis. A review of this challenging area of forensic pathology, including an explanation of these methods and markers, is presented in this paper. 相似文献
