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

Experimental postmortem interval estimation was assayed by various biochemical components of hens pectoral muscle. Among them, only percentage of non-protein nitrogen on total soluble protein, asparatic amino transferase activity and creatinine concentration showed significant correlation with time after death. Asparatic amino transferase was negatively correlated and non-protein nitrogen percentage and creatinine were positively correlated to postmortem interval. The stronger correlation (0.925) was found for creatinine. 相似文献

The disposition of cocaine in five cases of fatal poisoning are presented. The highest concentrations of cocaine were found in urine, kidney, spleen, brain, lung and skeletal muscle. Cocaine concentrations in these organs far exceeded those in blood. Cocaine was detected in all other specimens tested including: bile, heart, liver, vitreous and adipose tissue. These results are in agreement with limited, previously reported, tissue data, and indicate that when urine is not available, kidney, spleen, brain and/or lung should be the specimen of choice for cocaine detection. 相似文献

Abstract: Previous studies document characteristics of gunshot wounds shortly after they were inflicted. This study was conducted to determine if the early stages of decomposition obscure or alter the physical surface characteristics of gunshot wounds, thereby affecting the quantity and quality of information retrievable from such evidence. The study was conducted in August and September, 2005 in Nova Scotia, Canada in forested and exposed environments. Recently killed pigs were used as research models and were shot six times each at three different ranges (contact, 2.5 cm, and 1.5 m). Under these test conditions, the gunshot wounds maintained the characteristics unique to each gunshot range and changes that occurred during decomposition were not critical to the interpretation of the evidence. It was concluded that changes due to decomposition under the conditions tested would not affect the collection and interpretation of gunshot wound evidence until the skin was degraded in the late active or advanced decay stage of decomposition. 相似文献

Varices are the main clinical manifestation of portal hypertension, and their bleeding is the predominant cause of mortality from this condition. Periumbilical varices are known as “caput medusae.” Reports of their bleeding are rare, with only three fatal cases described in the literature. The antemortem diagnosis is relatively simple, while the postmortem diagnosis is more complex. This paper is the first report of fatal hemorrhage from a caput medusae for which the diagnosis was made postmortem, thanks to a complete diagnostic process including scene and circumstances, medical history, and autopsy with detailed histology. The circumstantial analysis showed the presence of a large amount of blood at the scene, blood which originated from a small abdominal wound; an analysis of the subject's clinical data reported that he was affected by portal hypertension. The autopsy revealed some dilated and convoluted veins in the subcutaneous tissue of the umbilical region; a fistula between these veins and the abdominal wound was detected. The histological study confirmed the presence of periumbilical varices, one of them ruptured and connected with the overlying skin. The cause of death was attributed to a massive hemorrhage generated by a periumbilical varix in a patient affected by portal hypertension. 相似文献

The primary objective of this paper is to report on the successful implementation of forensic facial approximation in a real case in the forensic context. A three‐dimensional (3D) facial approximation protocol of the skull was performed with free software, applying techniques in a virtual environment that have already been consolidated in the literature. The skull was scanned with the photogrammetry technique, the digital replica was imported in the Blender software (Blender Foundation, Amsterdam) and individualized model sketches of the face were traced with the MakeHuman software (MakeHuman Org) according to the anthropological profile of the victim. The face created was imported in Blender, where it was adapted, modeled, and sculpted on the 3D skull and its soft tissue markers, using an American open‐source application of the technique in the digital environment. The face created in a virtual environment was recognized and legal identification procedures were started, resulting in the more agile delivery of the disappeared body to its next of kin. It is therefore concluded that facial approximation may not be a primary method of human identification, but it can be satisfactorily applied in the forensic field as an individual recognition resource. It has great value in narrowing the search, reducing the number of alleged victims, and leading to identification tests, therefore significantly reducing the number of genetic DNA (deoxyribonucleic acid) tests—which are considered costly for the State or Federation—and consequently reducing the waiting time before delivery of the body to its family. 相似文献

Misdiagnosed PAS confirmed at medicolegal autopsy Pulmonary artery sarcoma (PAS) is a rare disease and usually indistinguishable from acute or chronic thromboembolic disease of the pulmonary arteries. We present a case of pulmonary artery sarcoma in a 54‐year‐old male, who was clinically misdiagnosed as pulmonary thromboembolism. The patient died of disease; however, the actual diagnosis of PAS was made after a medicolegal autopsy. PAS can be a diagnostic challenge for both clinicians and pathologists. In an autopsy case with a clinical suspicion of pulmonary thromboembolism, if there is an abnormal gross appearance in the pulmonary artery, the forensic pathologist should have a high index of suspicion of PAS, which should be ruled out by a histopathologic examination. 相似文献
