Objective: In order to heal burn wounds, many researches have been done, including the use of biological scaffolds due to their ability to achieve the desired properties. Owing to the appropriate biological properties of chitosan such as biocompatibility and antimicrobial properties as well as the promotion of wound healing in biomedical applications, we aimed to perform a systematic review to investigate the effect of this technology on the treatment of burn hazards victims.Methods: The present research was conducted in 2020 as a systematic review of studies related to the effect of chitosan on burns. In this study, Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Critical Appraisal Skills Programme (CASP) guidelines were used to assess the articles. The key words “Chitosan,” “Chitin,” “victim,” “Injury,” “Burn,” “Heal,” “wound” “treat,” “hazard,” and “care” were used in combination with the Boolean operators OR and AND. The ISI web of science, PubMed, Scopus, Science Direct, Ovid, Pro Quest, Wiley and Google Scholar were searched.Results: Recently, chitosan and its derivatives have been proposed as suitable candidates for scaffolding and can be used as temporary scaffolds to modify and stimulate the growth of new tissues. Studies to demonstrate the use of chitosan in the treatment of burns have been limited to research on animal models and have been superior to conventional therapies in terms of time, pain, and efficacy.Conclusion: The effect of chitosan on burns has been positive in animal models and has accelerated wound healing. Since the main ingredient of chit powder is chitosan and due to the limited studies done on humans, it cannot be said with certainty that the use of chitosan and its derivatives to treat burns is better than other ways to treat burns.

Objective: Determination of victim’s clothes in gunshot wounds is important due to the necessity of immediate workup in the emergency room as well as the legal aspects of cases. The aim of this study is to evaluate the importance of victim’s clothes in gunshot wounds referred to autopsy hall of legal medicine bureau of Tehran, Iran from 2014 to 2017.Methods: In this analytical comparative study, 202 consecutive cadavers of gunshot victims, referred to Tehran Legal Medical Hall from 2014 to 2017, were enrolled and the effect of shotgun and gunshot wound were determined and compared. Data were collected using a researcher-made questionnaire. The significance level of the tests was considered as P < 0.05. Spearman correlation coefficient and chi-square tests were used accordingly. The data were analyzed using SPSS software version 22.Results: In this study, all women were killed by gunshot. Also, all of the 26 people who were killed by shotgun were men. The mean of age only in males was 39-48 years for shotgun, and 29-38 years in both genders for gunshot. Evaluation of their clothes in the emergency room and autopsy hall was helpful in 70% of cases in order to determine shot distance and type of gun (P = 0.0001). Conversely, we did not observe a significant difference between sex (P = 0.082) and the pattern of death (P = 0.211).Conclusion: Based on the obtained results, it seems that some characteristics of victim’s clothes may be useful to differentiate shotgun and gunshot.
