[Ab] Resumo:OBJECTIVES: To analyze the relationship among electrical conductivity (EC), total volatile basic nitrogen (TVB-N), which is an index of decomposition rate for meat production, and postmortem interval (PMI). To explore the feasibility of EC as an index of cadaveric skeletal muscle decomposition rate and lay the foundation for PMI estimation. METHODS: Healthy Sprague-Dawley rats were sacrificed by cervical vertebrae dislocation and kept at 28 ℃. Muscle of rear limbs was removed at different PMI, homogenized in deionized water and then skeletal extraction liquid of mass concentration 0.1 g/mL was prepared. EC and TVB-N of extraction liquid were separately determined. The correlation between EC ( 1) and TVB-N ( 2) was analyzed, and their regression function was established. The relationship between PMI ( ) and these two parameters were studied, and their regression functions were separately established. RESULTS: The change trends of EC and TVB-N of skeletal extraction liquid at different PMI were almost the same, and there was a linear positive correlation between them. The regression equation was 2=0.14 1-164.91( ²=0.982). EC and TVB-N of skeletal muscle changed significantly with PMI, and the regression functions were =19.38 1³-370.68 1²+2 526.03 1-717.06( ²=0.994), and =2.56 2³-48.39 2²+330.60 2-255.04( ²=0.997), respectively. CONCLUSIONS: EC and TVB-N of rat postmortem skeletal muscle show similar change trends, which can be used as an index for decomposition rate of cadaveric skeletal muscle and provide a method for further study of late PMI estimation.

[Ab] Resumo:OBJECTIVES: To analyze the characteristics and mechanisms of pelvic fractures in the cases of road traffic accident deaths. METHODS: Total 65 cases of road traffic accident deaths with pelvic fracture were collected, and the sites, characteristics and injury mechanisms of pelvic fracture were statistically analyzed. RESULTS: Among the 65 cases of pelvic fracture, 38 cases of dislocation of sacroiliac joint were found, and most combined with pubis symphysis separation or fracture of pubis. In the fractures of pubis, ischium and acetabulum, linear fractures were most common, while comminuted fractures were most common in sacrum and coccyx fractures. There were 54 cases combined with pelvic soft tissue injury, and 8 cases with pelvic organ injury and 44 cases with abdominal organ injury. In the types of pelvic ring injury, 32 cases were separation, 49.32%, followed by compression, 26.15% and only one case was verticality, 1.54%. CONCLUSIONS: Detailed and comprehensive examination of the body and determination of the pelvic fracture type contribute to analyze the mechanisms of injury.

[Ab] Resumo:OBJECTIVES: To perform retrospective analysis on 20 dead cases related to heroin abuse, and to provide references for the forensic assessment of correlative cases. METHODS: Among 20 dead cases related to heroin abuse, general situation, using method of drug, cause of death and result of forensic examination were analyzed by statistical analysis for summarizing the cause of death and pathologic changes. RESULTS: The dead were mostly young adults, with more male than female. The results of histopathological examinations showed non-specific pathological changes. There were four leading causes of death, including acute poisoning of heroin abuse or leakage (13 cases, 65%), concurrent diseases caused by heroin abuse (3 cases, 15%), inspiratory asphyxia caused by taking heroin (2 cases, 10%), and heroin withdrawal syndrome (2 cases, 10%). CONCLUSIONS: The forensic identification on dead related to heroin abuse must base on the comprehensive autopsy, and combine with the qualitative and quantitative analysis of heroin and its metabolites in death and the case information, as well as the scene investigation.

[La] Idioma:eng
[Ab] Resumo:Postmortem computed tomography (PMCT) is a useful method to identify various causes of death and measure the volume of internal organs and gases. The purpose of this study was to investigate postmortem changes as measured by PMCT, and the relationship between the volume of organs and gases and postmortem interval (PMI). Forty-six cadavers (22 men, 24 women) were examined by CT before autopsy. The volumes of the lungs, intrahepatic gas, and intrarectal gas were measured by CT using a workstation. A stepwise regression analysis was used to establish a predictive equation to ascertain the measured volume using factors including sex, age, height, body mass index (BMI), body surface area (BSA), and PMI. For estimation of PMI, stepwise regression analysis was used. In the equations for each measured volume, height, diaphragmatic height, and BSA were adopted for the left lung; height and diaphragmatic height were adopted for the right lung; PMI was adopted for intrahepatic gas; and sex and PMI were adopted for intrarectal gas. In the PMI equations, left lung volume, intrahepatic gas, and intrarectal gas were adopted together with sex, weight, and BMI. Values of intrahepatic gas decreased with postmortem changes, while intrarectal gas increased. This may be useful in investigation of postmortem changes. It will be necessary to include other parts of the intestine and to analyze volume changes in gases from these parts after death.

[Ti] Título:Pediatric medicolegal autopsy in France: A forensic histopathological approach.

[Ab] Resumo:The aim of postmortem medicolegal examination in pediatric death is primarily to establish the circumstances and causes of death and to exclude child abuse. In France, pediatric death is systematically documented by medicolegal or medical autopsy. In case of medicolegal autopsy, the complementary examinations, requested and financed by justice, are rarely limited to a histopathological examination. However in medical autopsies other tools are available to the pathologist as toxicology, biochemistry and molecular biology. The purpose of this article is to evaluate the efficacy of forensic histopathology in pediatric forensic autopsies. We analyze the main causes of pediatric death in a forensic context. Between 2004 and 2015, 157 infant deaths were identified in Marseille university hospital. The forensic histopathology and autopsy reports of all 157 cases were available for systematic review. Medical or surgical causes represented 41,3% of deaths in our center, accidental causes 8.1% and child abuse 28,8%. The definitive diagnosis was made at autopsy in 30% of cases and at histopathological examination in 70% highlighting that forensic histopathology is an indispensable tool in pediatric medicolegal autopsies. Significant histological abnormalities may be detected in selected organs such as the brain, lungs, heart, liver, adrenal glands and kidneys in spite of macroscopically normal appearances. This justifies systematic sampling of all organs. Despite the implementation of the French sudden infant death protocol which recommends medical autopsies, too many pediatric autopsies are carried out in a medicolegal context. 30% of the cases remain without diagnosis at the end of the autopsy and histological examination. This number could be reduced by the contribution of others laboratory investigation.

[Ti] Título:Histological estimation of age at death in amputated lower limbs: Issues of disuse, advanced age, and disease in the analysis of pathological bone.
[So] Source:J Forensic Leg Med;53:58-61, 2018 Jan.
[Is] ISSN:1878-7487
[Cp] País de publicação:England
[La] Idioma:eng
[Ab] Resumo:Histological studies of healed bone tissue following amputation are relatively rare in the literature. This study describes the histomorphological features of femoral thin sections from six uni- and bi-lateral amputees of documented age and sex. Thin sections were cut from the midshaft of both the right and left femora from each amputee and analyzed following standard forensic methods for histological estimation of age at death from the human femur. The histological age at death estimations for the thin sections from amputated bone were consistently lower than the actual chronological age of each individual, suggesting that the effects of amputation prohibit the effective use of age at death estimation methods. The nature of each amputation is unknown, which suggests that alternative factors could be responsible for the slowed bone turnover seen in the thin sections from the amputated bone. First, it is reasonable to assume that the amputations in this sample could have resulted from complications of diabetes mellitus rather than trauma so the possible effects on bone remodeling due to disease are explored. Second, the mobility of the decedents following their amputations is unknown so the histomorphological results could be due to disuse osteoporosis.

[Ab] Resumo:Estimation of postmortem interval (PMI) is very important for judging the nature of cases, restricting the scope of investigation and suspect, which is always the emphasis and difficulty for forensic pathology. Early postmortem interval is the time between 0 and 24 hours after death. Due to the shorter time after the case occurred, precisely estimating early postmortem interval can help solve crimes, which has important significance in forensic medicine. In recent years, series of advanced methods and technologies are used to estimate the early PMI by the internal and overseas scholars who work in the forensic area. This paper reviews the research progress on fluids biochemistry, supravital reactions, metabolomics, imageology and the degradation rule of genetic material to provide a new idea to the study and application for estimation of early PMI.
