The authors conducted a retrospective study of 70 cases of homicide and suicide in the Toulouse region to identify the variables that enable us to determine whether a death is a homicide or a suicide. This work showed that the following characteristics-a female victim, numerous wounds, and the presence of 1 or more vertical chest wounds-suggest homicide. It also highlights the importance of inspecting clothing, in particular the position of clothing and the presence or absence of slashes. 相似文献

Bone samples are valuable for examining the cause of death and circumstance leading up to death when body fluids are not available for forensic toxicological analysis. Examined were heat-induced changes in methamphetamine and amphetamine concentrations in femurs removed from methamphetamine-injected mice to determine if the burned bones could be used for toxicology testing. The femurs were heated at 100°C, 300°C, or 500°C for 10 or 30 min. The tissue structure of the heated femurs was preserved at 100°C for 30 min but was destructed at higher temperatures. Methamphetamine and amphetamine were detected in femurs heated at 100°C for 10 min, 100°C for 30 min, and 300°C for 10 min (with methamphetamine and amphetamine concentrations ranging from 0.36 to 35 μg/g and 0.54 to 47 μg/g, respectively). Methamphetamine and amphetamine were detectable when heated above their decomposition temperature as a result of limited heat transfer do to protection provide by the femoral muscle. Thus, the bone could be a useful analytical sample in cases of burn-related deaths, where it is difficult to collect body fluids. 相似文献

Hepatic adenomatosis is a rare disease consisting of multiple adenomas in otherwise-normal liver parenchyma. Though the discovery of this entity goes back several years, its diagnosis is still challenging in terms of its definition and pathophysiology. Clinically, patients may be completely asymptomatic and the diagnosis is only made incidentally through imaging tests. The discovery could be made when complications occur such as intraperitoneal hemorrhage with hypovolemic shock due to the rupture of an adenoma. We report a fatal case of a ruptured adenoma in a case of hepatic adenomatosis discovered at autopsy. In order to achieve a better view of this disease, we conducted a literature review on this subject describing the pathogenesis, manifestations, and autopsy contribution to addressing this entity. 相似文献

Deaths due to electrocution are mostly accidental. Homicide by electrocution is rarely reported in the literature. However, the location and pattern of the electrocution wound can raise concern for a possible homicidal manner of death. We are reporting an unusual case wherein the dead body of a middle-aged man was found lying in a suspicious condition on the roadside of desolated area. There were circumferential, grooved electrocution lesions over the left and right second toes with oval electrocution lesions on the medial aspects of both the left and right third toes. There were split lacerations over the right high parietal region, right pinna, and forehead. There was avulsion of the nail of the left thumb. Pressure abrasion was consistent with a ligature mark on the lower part of the left leg. The locations and pattern of these injuries raised the possibility of torture infliction. Death was attributed to electrocution, which was confirmed by histopathology. Autopsy findings and possible inferences were furnished to the police. This case highlights the careful observation of different characterizations and locations of the wounds and deducing inferences about the possible manner of death. This information can be useful to investigating agencies. 相似文献

More than two decades ago, Marmarou published a valid model for producing diffuse axonal injury (DAI) in rats. Since then, both mild and severe injuries have been obtained by researchers using the original method and a weight of 450 g. However, the diffuse brain injuries produced in rats were only similar to those seen in humans when the rats sustained severe brain injuries. In these cases, rat mortality in the original article was around 50%, and the cause of death was prolonged apnea post-impact. Rat survival after impact is critical for studying the progression of DAI. In order to explain the cause of death in human victims with cranial trauma who do not show gross brain injury, testing for the presence of DAI is essential. Thus, in order to minimize local and cervical injuries to increase rat survival, attention should be paid to the following aspects: a wider head protector disc should be used, the head of the rat should be elevated at the time of impact, and the foam bed should be soft enough to allow the movement caused by acceleration. With our modified method, rat survival increased by 30% compared to the original model (80% versus 50%). Moreover, 85.7% of rats demonstrated DAI after 24 h of survival. With these modifications, injuries appear in the same locations as in humans; thus, the method is suitable for the study of traumatic DAI in humans. 相似文献

The goal of a medico-legal autopsy is primarily to determine the cause and manner of death. To this end, the pathologist often uses auxiliary analyses, including histology. However, the utility of routine histology in all medico-legal autopsies is unknown. Earlier studies on the utility of routine histology have shown inconsistent effects, with some studies recommending it and others rejecting it. To study the degree to which histology informs on the underlying cause of death, we sent autopsy reports from suspension-, immersion-, fire-, and traffic-related deaths to senior board-certified forensic pathologists and had them assess the cause of death, first without knowledge of the histological findings and then with knowledge thereof. Fifty cases were identified in each of four subgroups: fire-, immersion-, suspension-, and traffic-related deaths. The autopsy reports were anonymized, and the histological findings and conclusions were removed. Two board-certified forensic pathologists independently reviewed the reports in each subgroup and assessed the manner and underlying cause of death (including their certainty of this assessment on a five-level scale) with and without access to histological findings. The probability of changing the underlying cause of death posthistology was low in all study groups. There was a slight increase in the degree of certainty posthistology in cases where the underlying cause of death was not changed, but only when the antehistology certainty was low. Our results suggest that histology does not meaningfully inform on the underlying cause of death in suspension-, immersion-, fire-, and traffic-related deaths except when antehistology certainty is low. 相似文献

Human chorionic gonadotropin (HCG) is used in clinical medicine as a particularly important indicator to determine pregnancy. In this study, it was necessary to determine whether the urine spots on car seat fabric from a murder 5 years previously were from a pregnant woman. The HCG in the dried urine spot on a car seat was detected using an immunochromatography kit. It was found that the HCG in urine can be detected for much longer periods of time than the previously reported period of approximately 6 months. 相似文献
