Science continues to grow in this topic. Cartilage is a specific avascular, non-lymphatic, and non-nervous specific connective tissue. Objectives: This work aimed to assess the use of auricular elastic cartilage as a tool for estimation of late PM interval in human. Methods: Biopsies were taken from ear cartilages of 43 victims how died from suspicious criminal causes. Routine haematoxylin and eosin (H&E) staining was performed. The following histopathological parameters were examined, perichondrium, the number of lacunae with chondrocytes, nuclear material, and extracellular matrix. A scoring system was used for each parameter in different postmortem (PM) intervals. Results: Cases were classified into 3 groups (1-7, 8-14-, and 15-21-days PM). The examined histological parameters give statistically significant changes across the tested PM intervals. The correlation coefficient between the tested parameters and PM intervals gives significant results. The r-value was highest with the percentage of lacunae without chondrocytes and lowest with perichondrium loss (r = 0.62 and 0.35 respectively). Conclusion: Auricular cartilage showed remarkable changes that are correlated with PM interval in human. In the future, a large sample should be investigated with studying the impaction of environmental factors on these changes.","PeriodicalId":22435,"journal":{"name":"The Egyptian Journal of Forensic Sciences and Applied Toxicology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79926836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: The objective of this study was to determine the accuracy of the hard palate measurements and the rugae patterns in determining the sex of the Egyptian children. Patients and Methodology: The study included 210 children of either sex aged 6-12 years old. Alginate impressions from the maxillary arches have been taken. We measured the hard palate length, width, and height by using a digital caliper. We also obtained palatal rugae patterns from the maxillary casts. The patterns included the rugae length, shape, direction, and unification. Results: The mean palatal length, width, and height were significantly higher in males than females (p<0.001), and they displayed a significant-good power in predicting male sex (area under the curves (AUCs) were 0.85, 0.87, and 0.80 respectively). The median number of curved rugae was significantly lower in males (p=0.002), while the straight shape rugae exhibited a significantly higher number in males than females (p=0.004). Binary logistic regression revealed a model with excellent (AUC=0.968) power and overall accuracy of 91.43% for sex identification.

The aim of this study was to calculate standard measurements according to sex and age in morphometric analysis of the 4th costa using multi-slice computed tomography (MSCT). Material and Method: Measurements were taken on MSCT images of patients aged 20-70 years, who had undergone CT imaging for various reasons. Using the morphometric characteristics of the 4th costa and junction with the spine on the thorax CT images, measurements were taken of the angulation of the right and left 4th costa, the distance between the sternum and the vertebra, the distance between the two costae, the distance between the two ends of the right and left 4th costa separately, and the depth of the two costae. Adding age and gender to these variables, 10 parameters were evaluated in total. Results: As a result of the analyses, the mean values of right costovertebral angle, sternum-vertebra distance, inter-costal distance, left and right costa lengths, and left costa depth were found to be statistically significant according to sex. In the differentiation of age groups, the right costovertebral angle, the sternum- vertebra distance, and the right and left costa lengths were found to be statistically significant. Conclusion: The results of this study of a Turkish population showed that the morphometric properties of the 4th costa show differences in the determination of age and sex. With the benefit of these differences, it is possible to differentiate males and females, and even age groups. As there are societal differences, standard morphometric values have to be determined so it will be necessary to conduct these studies more widely and obtain appropriate standard values for every population.","PeriodicalId":22435,"journal":{"name":"The Egyptian Journal of Forensic Sciences and Applied Toxicology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88666900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drivers involved in some RTAs were found to be under the influence of different drugs. Marijuana effects on driving risks are not thoroughly understood. The study aimed to compare the pattern, severity, and clinical outcome of injuries between marijuana-smoking drivers and non-drugged drivers in RTAs. Patients and Methods: This prospective, comparative study was carried out on 78 drivers admitted to the emergency department, Tanta University Emergency Hospital during the period from the start of January to the end of December 2018. All drivers were subjected to history taking, clinical examination, assessment of injury severity score (ISS) and revised trauma score (RTS), and detection of tetrahydrocannabinol (THC) in urine. Results: Thirty-six drivers tested positive for THC with a median level of 314.6 ng/ml. There was a lack of significant association between marijuana smoking and the site of injuries. The marijuana-positive group had a significantly higher frequency of skull fractures, ruptured spleen, intraperitoneal hemorrhage, and abrasions on the body surface when compared to the marijuana-negative group. The median ISS was non-significantly higher, and the mortality was significantly higher in the marijuana-positive group. The THC level correlated significantly and strongly with both ISS and RTS. A significantly higher median THC level was detected in non-survivors compared to survivors.

T-lymphocytes have a fundamental role in the healing process of burn injury. The study aimed to characterize time-dependent changes in t-helper lymphocytes (cd4+) and tcytotoxic lymphocytes (cd8+) in human blood following thermal injury and to elucidate their accuracy in dating dry burn injury. Patients and methods: this cross-sectional study included adult patients, admitted with second and /or third-degree dry burn with a total body surface area ranged from 10% to 50%. Ten eligible patients were recruited independently at the 1st, 3rd, 7th, and 15th days following burn injury. Additionally, ten matched healthy subjects served as a control group. Besides the patient’s information, blood samples were withdrawn from each participant for flow cytometric analysis of cd4+ and cd8+ tcells. Results: percentages of cd4+ and cd8+ cells, and cd4+/cd8+ ratio exhibited a significant reduction in burnt patients compared to the control group throughout the first week after-burn. Additionally, there was a significant time-dependent decline between the 1st, 3rd, and 7th days, following the burn. Receiver operating characteristic (roc) analysis for these markers revealed a significant-excellent power of discrimination of burns aged less than 3 days (area under the curves were ≥0.9).
