Backgroud firearm injuries are a significant public health problem facing young people in the USA.In 2015,a total of 16878 people under 19 years old were injured or killed by firearms.To reduce firearm injuries,29 states and Washington,DC have enacted child access prevention(CAP)legislation.CAP legislation is intended to reduce the likelihood of a minor obtaining a weapon and subsequent injury or death.This study evaluates the impact of CAP legislation based on language of the legislation,specifically it evaluates a relationship of the legal threshold of liability and the number of firearm injuries per capita of minors.Methods Data were collected from the Web-based Injury Statistics Query and Reporting System for patients less than 19 years of age who presented to emergency departments with firearm injuries in 2016.The Giffords Law Center classification was used to group states into three categories(strong/weak/no CAP)based on CAP language.Differences of firearm-related injury rates per capita were assessed.Results When controlling for population,states with CAP legislation had a 22%decrease in firearm injuries per capita compared with states without CAP legislation.States with‘strong’CAP legislation had a 41%decrease in firearm injuries per capita compared with states with‘weak’or no CAP legislation when controlling for population.Conclusions States with‘strong’CAP legislation had lower pediatric firearm injury rates per capita,but more complete data and further studies are needed to evaluate this relationship as well as other factors that may impact firearm injury rates.

BACKGROUND firearm-associated injuries(FAIs)are among the leading causes of morbidity and mortality in children living in the United States.Most victims of such injuries survive,but may experience compromised function related to musculoskeletal injuries.Although complex firearm-associated fractures(FAFs)often require specialized orthopaedic,vascular,and plastic surgical intervention,there is minimal research describing their management and outcomes.The purpose of this study is to describe the epidemiology and presentation of pediatric FAFs,as well as evaluate the management and outcomes of these injuries.AIM To describe the epidemiology and presentation of pediatric FAFs,as well as evaluate the management and outcomes of these injuries.METHODS A retrospective chart review was performed at a major,pediatric level 1 trauma center.The study included patients aged 18 or younger who presented with FAIs between 2008-2018.Additional data was collected on patients with FAFs including demographic and clinical data such as age,sex,race,payor type,fracture location,injury severity score(ISS),and radiographic and clinical outcomes.The management of FAFs was analyzed as well as need for readmission and reoperation.Descriptive statistics were used to summarize the results and univariate analyses were performed to assess differences between groups.RESULTS Between 2008 and 2018,there were a total of 61 patients who presented with FAIs.In this cohort,21 patients(34%)sustained FAFs(25 fractures)with a mean age of 11(Range:10 mo to 18 years old)at the time of presentation.Approximately 52%(n=11)of patients with FAFs were male,76%(n=8 and n=8,respectively)identified as black or other,and 71%(n=15)had government insurance.FAFs were most commonly noted in the upper extremity(n=7)and lower extremity(n=6).In patients with FAFs,the mean ISS at presentation was 11.38(Range:2-38),and 24%of patients(n=5)were classified as having a major trauma.There were no significant differences in age,sex,race,and payor type in FAF patients that presente

European firearms entered China from the sixteenth century and played a significant role in the warfare of the Ming and Qing dynasties.Some Chinese military books,which include contents on European firearms,appeared in the early seventeenth century and helped to expand the weapons’influence.Certain parts in these books concerning European artilleries are highly similar,indicating that they might have been extracted from a mutual source.Bing lu兵錄(Records of military art)is a typical example of such Chinese military treatises.Its illustrations and data demonstrate that Pratica manuale di arteglieria written by Luys Collado in 1586 is an important source of the Western knowledge in certain chapters of Bing lu.

The study was supported by the grants from the Medical Scientific Foundation of People's Liberation Army of China. Objective To make clear the range of firearm wound in the maxillofacial region, the optical repair time and the characteristics of accompanied indirect brain damage, and to offer the principle of emergency treatment and the early repair of war wound. Methods With the aid of the standard Sweden model, 200 dogs were used in the experiment. Varies tissues around the primary canal were harvested chronologically, in different zone and different tissue, for histopathological examination. Results The necrotic range of various tissues in the maxillofacial region was less than that in the extremities. In the maxillofacial region, there was a significant temporary cavity following the passing of bullet, which caused indirect brain damages. Conclusion These findings are helpful to the treatment of war wound in the maxillofacial region. Early bone transplantation using microvascular anastomosis in the treatment of gunshot wound in the maxillofacial region is recommendable.

Introduction: Thoracic wounds by firearms are frequent and severe. They may involve the patient’s prognosis. Objective: To study the epidemiological, clinical, paraclinical, therapeutic and evolutionary aspects of the thoracic wounds by firearms. Material and method: This was a cross-sectional, descriptive study of all patients over the age of 15 who consulted in the university hospital-YO in the department of general and digestive surgery over a period of 5 years. Results: We collected 50 cases of thoracic wounds by firearms on 183 thoracic wounds with a prevalence of 27.3%. There were 48 men (96%). The average age was 30 years. The patients came from urban areas in 66% of cases;the informal sector accounted for 44% of the cases. The pistol was the most involved firearm (46.9%). The consultation period was less than 6 hours in 78% of patients. An unstable hemodynamic state was found in 42% (n = 21). A fluid and mixed pleural effusion syndrome was found in 46% and 26% of patients, respectively. Associated lesions were diaphragm involvement, and lesions of intra-abdominal hollow organs. Thoracic drainage was performed in 24 patients (48%) and was associated with a laparotomy in 8 patients. The average hospital stay was 7.5 days. Mortality was 14%. Conclusion: the thoracic wounds by firearms are frequent in civilian practice. The thoracic CT allows mapping of the lesions and thoracic drainage constitutes the essential part of surgical treatment. The fight against the proliferation of weapons deserves to be promoted.

Analysis of crime scenes involving single-fire-gun projectiles requires the determination of the direction of arrival of a projectile at the target and other factors to reconstruct events.The movement of a projectile can be analyzed by applying Euler’s equations to a solid symmetrical rigid body.The present work starts from a Newtonian reformulation of these equations to show that,in the presence of a gravitational field,the system can be expressed with a complex variable nonlinear equation,where the inclusion of small nutation variables allows us to find possible solutions.As a particular case,we analyzed the movement of a 9-mm projectile fired from distances greater than 1 m to demonstrate that the direction of arrival of the projectile at the target cannot be traced by a stick placed in the target hole,as is usually performed in crime investigations.A series of shots were fired from distances varying between 1 m and 7 m.Impact data were recorded on Riemann planes of projection for the description of nutation and precession motions,allowing the observation of the motion dynamics of the projectile.We show that the direction of arrival at the target can be determined approximately from the analysis of the nutation and precession curves through Riemann planes of projection.The results presented in this work will allow more accurate judgements to be made in judicial investigations.

In this study, a complex analysis of a man-weapon interaction based on experimental effort is presented.The attention is focused on how a shooter can influence on a rifle, opposite to generally considered in literature rifle's impact on a shooter. It is shown, based on the kbk AKM weapon, that each support point of the rifle has an substantial impact on the system. It is said that identifying human reactions on weapon may let to describe gun movement and thus may be applied to weapon accuracy determination.

Fracture by firearms is a surgical emergency. The aim of our study was to report our experience in the management of open fractures by firearms and monitoring with a decline of 6 months the lesions observed in peacetime. This retrospective study over 3 years (January 2007-November 2010), supplemented by a prospective (December 2010-November 2011) is based on an analysis of operative reports and clinical records of patients admitted to the Yaoundé Central Hospital. 29 cases were selected, including 35 lesions were observed. Our series consists of 27 men and 2 women, mean age 30 years. 40% of our patients were initially supported (debridement) before the 6th hour and 51.42% between the 6th and 24th hours. In terms of internal fixation, these figures were 66% between the 25th and 96th hours. The type of material was used as the external fixate (64.9%). Conversion processing by the establishment of an internal hardware, after 3 - 6 weeks and control NFS (numeration of blood count or blood count), VS (rate of sedimentation), CRP (C reactive protein). Unfortunately this has been possible only in two cases because of financial means. In 40% of cases, surgical outcome was simple, and complications to a type of osteomyelitis, shortening, suppuration in 42.7% of cases.
