The precise mechanism for brain swelling is unclear. Materials and Methods: We examined cerebral tissue from ten pediatric deaths due to blunt force trauma, along with seven control infants who asphyxiated in unsafe sleep environments. To assess the competence of the blood–brain barrier, we performed immunohistochemical stains for albumin and immunoglobulin G (IgG). Results: IgG and albumin were increased in subpial and superficial perivascular tissue in those cases due to blunt force trauma, and in particular, the blunt force trauma associated with subdural hematoma. This included two deaths at the scene without hospital survival time. Conclusions: Our findings suggest disruption of the blood–brain barrier with vasogenic edema as an early event in head trauma involving young children upstream of global ischemic brain injury. We hypothesize that mechanical injury to the cortical vasculature results in vasogenic edema by oncotic (increased plasma proteins in the cortical interstitium) and hydrostatic (increased capillary pressure) mechanisms, with subsequent cortical ischemia. This may explain why ischemic sequelae appear to occur in head trauma involving young children, regardless of whether anoxia, hypotension, or cardiac arrest complicate the disease course and may in part underlie the high morbidity and mortality of head trauma in early childhood.","PeriodicalId":36434,"journal":{"name":"Journal of Forensic Science and Medicine","volume":"8 1","pages":"41 - 45"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47349340","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}

Aim: The aim of the study was to test the suitability of two genetic markers based on conducting the molecular identification of six necrophagous Calliphorid flies. Materials and Methods: Fourteen Calliphoridae flies were collected and classified with traditional morphological characteristics. The DNA of flies was extracted and the fragments of COI and ITS2 were amplified and sequenced. All the sequences were aligned and analyzed by MEGA 7 software for NCBI BLAST, nucleotide composition, intra- and inter-specific divergence calculation, and phylogenetic tree inference successively. Results: The results indicated that COI and ITS2 genes were robust in the identification of Calliphoridae at the species level and ITS2 gene sequence possessed a strong resolution power as it showed higher variation values between Lucilia sericata and Lucilia cuprina, Calliphora vomitoria and Triceratopyga calliphoroides, C.vomitoria and Aldrichina grahami, but inferior to COI for T. calliphoroides and A. grahami. Conclusions: Our results showed that combination of COI + ITS2 genes yields more accurate identification and diagnoses and better agreement with morphological data than the mitochondrial barcodes alone. As a supplementary method for morphological identification, we advocated for the combination of nuclear and mitochondrial gene approaches to address the taxonomy and phylogeny of forensic relevant flies, especially of closely related species and populations.","PeriodicalId":36434,"journal":{"name":"Journal of Forensic Science and Medicine","volume":"8 1","pages":"11 - 16"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44777893","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}

The persistence of the virus after infected individuals die remains unclear. This article reports the findings taken from postmortem nasopharyngeal swabs performed to investigate the presence of SARS-CoV-2 in the corpses transferred to the Genoa District Mortuary from the outset of the Italian lockdown (March 9) to the end of the first emergency phase (July 13). One hundred and eighty swabs were carried out: 13 corpses resulted positive for the virus, with the diagnosis being reached only after death. Seven were male and 6 female with an average age of 73.5 years old. The most frequent comorbidities recorded were arterial hypertension, diabetes, Alzheimer's, and pulmonary disease. In two cases, the swab tested positive at a distance of 125 h and 165 h from actual death. The nasopharyngeal swab results a useful way to screen corpses for COVID-19 and to handle bodies in Legal Medicine Centers where safe autoptic rooms are not available. Swabs are also a means of safeguarding forensic pathologists, identifying the presence of breeding grounds in the community and providing information for the Public Prosecutor's Office in legal cases. They are able to produce reliable results up to at least 7 days following death, provided that the corpse is correctly preserved.","PeriodicalId":36434,"journal":{"name":"Journal of Forensic Science and Medicine","volume":"8 1","pages":"24 - 31"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44893497","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}

Previous studies have shown that morphological characteristic of frontal sinus is distinctive to particular individual and hence, literature suggests that it can be used in establishing identification of a person. However, few researches have concluded that, its use in determining sexual dimorphism is limited. Aim: This study aimed to evaluate frontal sinus index using cone beam computed tomography (CBCT) and differentiate sex dimorphism based on the index obtained. Materials and Methods: A retrospective cross-sectional study was undertaken using three-dimensional-CBCT scans. By simple random sampling method, 150 scans were selected, out of which 74 were of male and 76 were of female within the age group of 20–64 years. The frontal sinus width and the height were measured, and the ratio was taken as frontal sinus index. This index was correlated to the differentiation of sex. Data were analyzed using SPSS, and sex dimorphism was assessed using discriminant function analysis. Results: The mean height of the frontal sinus in both males and females was 30.12 ± 7.6 mm and 30.14 ± 7.8 mm, respectively. The mean width of frontal sinus in males (13.39 ± 3.6 mm) was slightly more than that of females (12.06 ± 3 mm). Conclusion: The parameter frontal sinus index measured using CBCT was found to be a contributing factor in sex determination in forensic identification within the sample population.","PeriodicalId":36434,"journal":{"name":"Journal of Forensic Science and Medicine","volume":"8 1","pages":"1 - 5"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41938946","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}
