In order to cooperate with voluntary screening programs aimed at the surveillance of the HIV epidemic in Finland, we have studied medicolegal autopsies for HIV antibodies since 1986 using an enzyme immunoassay on postmortem sera. The investigation covered 47.4% and 39.2%, respectively, of all deaths under the age of 65 years in the metropolitan areas of Helsinki and Turku--two cities on the densely populated southern coast of Finland from which most HIV infections have thus far been detected. Nine HIV-positive cases (0.12%) were detected among the 7305 medicolegal autopsies tested in 1986 to 1990. This figure is higher than the prevalence of 0.01 to 0.03% in voluntary screening programs for the general population would suggest. Seven of our cases had previously tested positive, and two were previously unknown cases, indicating that people at high risk are clustered in the medicolegal autopsy series. Of the six cases in an early stage of infection, three committed suicide suggesting the importance of HIV-screening in suicide cases in tracing symptomless HIV carriers. Five of the cases were detected in 1990, a year when the number of new HIV infections had more than doubled compared to the previous two years. This suggests that testing of medicolegal autopsies as surrogate tests for the population gives useful information even in low-prevalence areas like Finland. Such testing has none of the ethical problems of many other back-up surveys, and may be particularly sensitive to early changes in epidemiology.  相似文献

宗教财产的归属问题既是政治问题,也是法律问题,但终归要在法治的轨道上通过对宗教财产归属制度的重构加以解决。宗教财产应当依据不同情形,分别确定归属于宗教法人、国家和私人所有。鉴于宗教财产所有权为一项重要的民事权利,建议在民法典中予以明确规定。  相似文献

The conflict and animosity that sometimes accompanies child custody disputes can give rise to the propagation of allegations of child sexual abuse. To characterize the magnitude of the problem, the present study attempted to determine whether and to what extent child sexual abuse allegations predominate in family court litigation. The entire one-year caseload of a county family court docket was systematically reviewed and coded. Methodical evaluation of 603 family court files yielded base rates of pertinent allegations and other information profiling the cases. The findings did not support the contention that sexual abuse allegations are commonplace in child custody disputes. Sexual abuse allegations were made in 2% of cases in which custody or access was contested and in only 0.8% of the cases overal. Implications of the findings for future research were discussed.The authors gratefully acknowledge the assistance of the Honorable William R. Campbell and Barbara Scott, Clerk of Court for the South Carolina Fifth Judicial Circuit, as well as the contributions of Angie Newton, Frank Robinson, and Kimberly Ellis in the data collection process.  相似文献

Ethanol was determined by gas chromatography in a variety of tissues and body fluids secured at autopsy in 61 cases. The specimens tested included right and left heart blood, femoral blood, pericardial fluid, cerebrospinal fluid, vitreous humor, urine, stomach contents, and brain. Statistical analysis of the cases revealed no significant differences among the various blood sites tested. However, the variations in blood ethanol concentrations among the various sampling sites within each case were as follows: 40 cases showed differences of less than 25%; 16 cases revealed variability between 25% and 50%, 4 cases had differences exceeding 50%. In one case, satisfactory blood analyses could not be accomplished. The larger variances occurred especially in those instances in which stomach alcohol concentration was 0.50% or greater. In one case, the variability amongst the different blood sites exceeded 400% (femoral blood--0.043%, right atrium--0.070%, root of aorta--0.156%); the brain was 0.050%, and the stomach contents was 1.2%. For all 61 cases, variances in blood alcohol content among the different sampling sites in a single cadaver ranged from 1.8 to 428%.  相似文献
