Medical examiners frequently deny requests by tissue procurement organizations for heart valves intended for allograft transplantation. Most of these denials are in cases of sudden apparent natural death, often where a cardiac cause is suspected. The basis of denial in these cases is that the heart must be removed and the valves procured off site under sterile conditions. This prevents the medical examiner from determining and documenting the cause of death. A dissection technique was therefore devised to increase the number of heart valves available for allograft transplantation and to simultaneously allow the pathologist to document a cardiac cause of sudden death. Interagency procedures, the dissection technique, and case summaries are provided. 相似文献

To combat the effects of pretrial publicity, a court may consider a change of venue, moving the trial to a jurisdiction that has been exposed to little publicity about the case. Social scientists can be of valuable assistance in measuring community attitudes regarding defendant level of guilt and case familiarity. This paper discusses obstacles faced by the authors when conducting change of venue surveys and presenting their findings to the court, including challenges to their ability to act and be viewed as scientists, and pressures to do that which contradicts empirical research in order to please the court. Future research should examine factors predicting judges' decisions on change of venue motions and issues associated with small venues and civil cases. 相似文献

This article reports a State Justice Institute funded research project attempting to demonstrate the difference between mediation and evaluation disputes over child custody, and visitation where domestic violence is involved. The researchers attempted to develop samples at two courts—Hennepin County Circuit Court in Minneapolis, Minnesota, and Multnomah County Circuit Court in Portland, Oregon. 相似文献

The purpose of this investigation was threefold: to document the number of cases in Shelby County, Tennessee where an insanity
defense was possible: to follow cases through to disposition to determine what percentage of defendants use the defense successfully;
and to examine the type of charges for insanity cases. Of the 25.000 individuals processed through the Criminal Courts. 685
(2.7%) were referred for insanity evaluations and 45 defendants (6.6%) were returned to the court with a recommendation from
the Midtown Mental Health Center's Forensic Team that an insanity defense was possible. Of the 45 insanity defendants identified,
49% (n=22) pleaded guilty, 31% (n=14) went to trial, and 20% (n=9) were dismissed. Overall, 22% (n=10) of the insanity defendants
were adjudicated not guilty by reason of insanity. Thus, of all defendants processed (25,000), 04% (n=11) were adjucated not
guilty by reason of insanity. While no one type of offense predominated, two general categories were observed: murder and
related offenses (33%) and property crimes (27%). The findings are discussed with reference to procedures for handling insanity
cases in Tennessee and the position that extreme caution should be exercised before investing substantial resources to effect
sweeping changes in laws that effect so few criminal defendants. 相似文献

Fatal autoerotic asphyxia refers to death during solitary sexual activity with self-induced asphyxiation meant to be brief and reversible. However, an unexpected fatality results from a failure of a release mechanism apparatus. The large majority of victims of autoerotic death are Caucasian males between the second and fourth decade. While autoerotic death may encompass a myriad of other means of achieving sexual gratification, which includes asphyxia by plastic bag or inhalation of noxious chemicals, the most common method is by ligature about the neck. This study presents a 9-year retrospective review of deaths due to autoerotic asphyxia, specifically ligature asphyxia, in Kentucky between 1993 and 2001. Of the sixteen victims, all were Caucasian males between the ages of 14 and 59 years, with a mean age of 38.3 years. Cross-dressing was a feature in 4 cases. A thorough review of the decedent's background, meticulous scene investigation, and complete postmortem examination may shed light on the mechanism and psychosocial predisposition associated with autoerotic asphyxia. 相似文献

Autoerotic fatalities encompass a wide array of means and mechanisms used to attain sexual gratification. The most commonly encountered autoerotic practice, specifically, autoerotic asphyxia, denotes death resulting from failure of a release mechanism of the apparatus designed to attain cerebral hypoxia for heightened arousal. Historically, the majority of victims of autoerotic death are Caucasian males under the age of 30. While autoerotic death is most often associated with a constrictive cervical ligature tied to either other parts of the victim's body or to an inanimate object such as a door, several other methods have been reported. These modalities include ligature around the thorax or abdomen, plastic bags covering the face, electrical current, inhalation of a toxic gas or chemicals, or partial or total submersion, known as aquaerotic asphyxiation. This study highlights 11 cases of atypical autoerotic death, including asphyxia with a plastic bag, electrocution, and inhalation of butane and nitrous oxide (N2O). Whereas the manner of death in the majority of autoerotic death cases is deemed accidental, we present and analyze unique and equivocal cases representing 4 different manners of death: accident, natural, suicide, and homicide. The 11 victims were all Caucasian and between the ages of 17 and 55. Ten decedents were males, 1 female. A comprehensive investigation incorporating a thorough scene analysis, gathering of the victim's history, and complete postmortem examination is necessary to elucidate both the cause and manner of death in these atypical cases. 相似文献

The purpose of this study was to evaluate the efficiency of the Cozart RapiScan (CRS) drug test system for detecting opiates and cocaine in oral fluid. Oral fluid samples were collected using the Cozart RapiScan collection system from 358 donors who were receiving treatment for their addiction and were monitored for drug misuse. A further 103 oral fluid samples were collected from volunteer donors who were not drug users. The samples were analyzed in the laboratory using the two-panel Cozart RapiScan cartridge for opiates and cocaine and confirmed using gas chromatography-mass spectrometry (GC-MS). The samples were stored frozen at -20 degrees C until analysis by GC-MS. The overall accuracy of the CRS for both opiates and cocaine was 100%. Samples spiked at 50% above and below the cut-off consistently gave negative and positive results respectively. A total of 88 samples were positive for various opiates and 111 samples were positive for cocaine and/or its metabolites. The CRS for opiates and cocaine in oral fluid, using a cut-off of 30 ng/mL morphine or benzoylecgonine equivalents in neat oral fluid, had overall efficiencies of 98% and 99%, respectively, versus GC-MS. A series of potential adulterants of oral fluid were evaluated and shown not to alter the outcome of the test result. 相似文献

The purpose of this study was to determine the performance characteristics of the Cozart microplate EIA for detecting opiates in oral fluid from patients in a drug misuse treatment program. Oral fluid samples were collected using the Cozart RapiScan Collection System from 216 donors who were receiving treatment for their addiction and were monitored for drug abuse. A further 40 oral fluid samples were collected from volunteer donors who were not drug users. The samples were analyzed in the laboratory by using the Cozart microplate EIA for opiates and confirmed using gas chromatography-mass spectrometry (GC-MS). The samples were stored frozen until analysis by GC-MS. The intra-assay precision for the Cozart microplate oral fluid EIA for opiates over 40 assays was 0.43% to 9.13% CV (within assay) and 2.9% to 9.1% CV (within day). A total of 109 samples were positive for various opiates. The Cozart microplate EIA for opiates in oral fluid, using a cut-off of 30 ng/ml morphine equivalents in neat oral fluid, had a sensitivity of 99.1 +/- 2.1% and a specificity of 94.4 +/- 2.2% versus GC-MS. A series of potential adulterants of oral fluid were evaluated and shown not to alter the outcome of the test result. 相似文献
