Post-mortem diagnosis of chronic alcohol abuse is a challenge for forensic experts due to the lack of pathognomonic morphological findings and often also inadequate background information. Objective methods demonstrating chronic excessive alcohol consumption would therefore be a useful tool for forensic pathologists. In clinical practice, several markers of chronic alcohol abuse have recently been introduced, among which carbohydrate-deficient transferrin (CDT) is the most accepted, but the use of these markers in autopsy has not yet been established. We examined post-mortem stability and possible post-mortem redistribution of CDT and compared two analytical methods, capillary zone electrophoresis and high-performance liquid chromatography. According to our results, CDT remains stable for an appreciable time after death. The results further indicate that CDT is not subject to major post-mortem redistribution. 相似文献

Abstract: The aim of this study was to work out a biometric method for personal identification by comparing simulated antemortem and postmortem digital radiographs of unrestored teeth. Intra‐oral radiographs of the inferior right first molar, without restorations, were acquired at two different times in 70 subjects using a standardized technique followed by a morphometric analysis. The program automatically supplied values of the absolute distances, relative distances, shape factors, moments, perimeter values, and the areas of the triangles, which were obtained by joining key reference points. The values for the homologous samples were compared with the heterologous samples. Statistical analysis was then carried out, resulting in a section point value of 0.9992. Higher correlation coefficients indicate positive identification, with less than 2% risk of false positives, and approximately 3% of false negatives. We have also tested the method on dental records from 30 patients in order to demonstrate the specificity and sensitivity of the system. 相似文献

This article examines the factors that influence the willingness of police officers to comply with decisions made by police command staff. In particular, this research focuses on the extent to which officer ethnicity interacts with perceptions of procedural justice in influencing officer compliance. The data for this study were drawn from an anonymous mailed survey (n = 648) examining officer attitudes toward the complaint investigation process in one large municipal police department. Structural equation modeling demonstrates that ethnicity does influence officer compliance, but only weakly and indirectly. Latino/a officers are less likely to report trust in police internal affairs than White officers, and thus somewhat less likely report that they are willing to comply with command staff decisions. Other factors, such as morale, perceptions of procedural justice, and rank, prove to be much more powerful predictors of officer compliance than ethnicity. 相似文献

Abstract: Toxic epidermal necrolysis (TEN) is characterized by fever, scalded appearance of the skin, and epidermolysis associated to blister formation and exfoliation, and it is caused by hypersensitivity reaction to a drug. The authors report two cases of death as a result of TEN; both referred to old aged women treated with a polytherapy including allopurinol. Both patients displayed erythematous skin lesions similar to scald burns and epidermolysis at the face, chest, and abdomen and died shortly after hospitalization. Autopsy findings and histological examinations revealed epidermal necrolysis and confirmed the clinical diagnosis. A strict time‐correlation between allopurinol administration and symptoms was evidenced. Because of its iatrogenic origin, TEN often arises suspicions of medical liability; however, because of its unpredictable nature, the occurrence of this syndrome cannot be ascribed to the medical staff whose main task is the rapid diagnosis and the correct management. 相似文献

Abstract: Foods contaminated with a granulated material similar to Temik (a commercial pesticide formulation containing the carbamate insecticide aldicarb) are often involved in accidental ingestion, suicides, and homicides in Brazil. We developed a simple technique to detect aldicarb. This technique is based on the inhibition of a stable preparation of the enzyme acetylcholinesterase, and it is specially adapted for forensic purposes. It comprises an initial extraction step with the solvent methylene chloride followed by a colorimetric acetylcholinesterase assay. We propose that results of testing contaminated forensic samples be expressed in aldicarb equivalents because, even though all other carbamates are also potent enzyme inhibitors, aldicarb is the contaminant most frequently found in forensic samples. This method is rapid (several samples can be run in a period of 2 h) and low cost. This method also proved to be precise and accurate, detecting concentrations as low as 40 μg/kg of aldicarb in meat samples. 相似文献

Abstract: In this study, we analyzed the entire mtDNA control region in 61 unrelated individuals from the Pas Valley (Cantabria), a human isolate from northern Spain, to evaluate the suitability of this analysis to increase the power of discrimination of this locus for forensic purposes in human isolates. Low values obtained for the diversity parameters confirmed the relative isolation of this human group. The main findings of this study indicated that even the analysis of the entire mtDNA control region may have important limitations for use in forensic casework when dealing with human isolates: none of the 44 individuals who exhibited identical HVI‐HVII haplotypes could be further differentiated by analysis of segment HVIII. Nevertheless, analysis of the entire mtDNA control region proved to be useful to determine the ancestry of the samples examined, by contributing to the confirmation, and, on occasion, even to the refinement of the haplogroup assignment. 相似文献
