In three cases a phenomenon is reported, seen on the skin of bodies found dead after a longer time of lying in bathtubs filled with water. The sign was parallel to the surface of the water and showed a breadth up to about 1 cm. Contrary to the surrounding skin, the mark was characterized by paleness and clearly les distinct formation of postmortem alterations as put-refaction. Searching for an explanation, temperature measurements were performed in model. The results showed the marginal paleness of the skin to be a thermal phase transition phenomenon. This mark has a forensic message too: it demonstrates a longer remaining of the corpse in the corresponding position, is a statement concerning the high of the water level, and allows a reconstruction of the original situation after manipulation, but is no sign of vital reaction.  相似文献

'Area approaches' have become a new conventional wisdom for dealing with urban deprivation. Such thinking is evident in Michael Heseltine's Liverpool 'initiative'. This article contributes to an emerging critique of such approaches, by highlighting some political and organizational problems rather than stressing their incipient economic difficulties. Arguably the biggest anti-deprivation project in Western Europe, the Glasgow Eastern Area Renewal scheme (GEAR) is taken as a case study. Official claims of success are juxtaposed against an alternative perspective outlining possible weaknesses and dilemmas. Critical analysis leads to the conclusion that the GEAR constellation of organizations may be best regarded as a mutually non-effective organizational set. The persistence of such an institution, while serving short-term political and administrative needs, may unwittingly produce longer-term negative political and social consequences. The authors argue that if such problems are to be avoided in the future, the political and organizational drawbacks of this type of initiative must be appreciated.  相似文献

Persons afflicted with acquired immune deficiency syndrome (AIDS) or its preceding medical conditions face a potential problem with assured access to basic threshold medical care. Subject to certain limitations, there is no guarantee that a physician will fulfill the health care needs of any population of patients. Individuals with AIDS, thus, have a considerable interest in the development of a duty on behalf of physicians to provide treatment. This Note first highlights the limits of the legal duty to treat. It then examines the theoretical impetus propelling an ethical duty to treat. The Note concludes that the grounds for imposing an ethical duty on physicians are too weak to support that result, but the creation of an AIDS-specific legal duty is a viable alternative.  相似文献

To examine a possible relationship between pineal function and the sudden infant death syndrome (SIDS), samples of whole blood, ventricular cerebrospinal fluid (CSF) and/or vitreous humor (VH) were obtained at autopsy from 68 infants (45 male, 23 female) whose deaths were attributed to either SIDS (n = 32, 0.5-5.0 months of age; mean +/- S.E.M., 2.6 +/- 0.2 months) or other causes (non-SIDS, n = 36, 0.3-8.0 months of age 4.3 +/- 0.3 months). The melatonin concentrations were measured by radioimmunoassay. A significant correlation was observed for melatonin levels in different body fluids from the same individual. After adjusting for age differences, CSF melatonin levels were significantly lower among the SIDS infants (91 +/- 29 pmol/l; n = 32) than among those dying of other causes (180 +/- 27; n = 35, P less than 0.05). A similar, but non-significant trend was also noted in blood (97 +/- 23, n = 30 vs. 144 +/- 22 pmol/l, n = 33) and vitreous humor (68 +/- 21, n = 10 vs. 81 +/- 17 pmol/l, n = 15). These differences do not appear to be explainable in terms of the interval between death and autopsy, gender, premortem infection or therapeutic measures instituted prior to death. Diminished melatonin production may be characteristic of SIDS and could represent an impairment in the maturation of physiologic circadian organization.  相似文献

Cardiovascular disease continues to be the single most common generic cause of sudden and unexpected deaths. Atherosclerotic coronary heart disease and acute myocardial infarction are the most prevalent forms of fatal cardiac disease observed at autopsy. Other cardiac lesions are frequently listed as causes of death, but the prevalence of such lesions as incidental findings in the general population is unknown. In this study, 470 consecutive forensic autopsies were evaluated for minor and major anomalies. The most frequently observed major congenital finding was floppy mitral valve (5%). Tunneled coronary arteries, considered minor congenital findings, were seen in 29%. Atherosclerotic coronary heart disease was the most common major acquired finding, observed in 16% of cases. Of the 470 hearts, only 8% were considered normal.  相似文献
