Maxillo-orbital gunshot trauma in a pediatric patient

Gunshot injuries to the maxillofacial region vary in severity from minor harm to critical situations necessitating urgent medical intervention. Effective handling of facial gunshot wounds mandates a multidisciplinary approach to deliver thorough care to the individual.We present a pediatric patient presenting to the Emergency Department following an accidental machine gun injury.

Public Mass Shootings: Counterfactual Trend Analysis of the Federal Assault Weapons Ban.

Assault weapon and large-capacity magazine bans are potential tools for policy makers to prevent public mass shootings. However, the efficacy of these bans is a continual source of debate. In an earlier study, we estimated the impact of the Federal Assault Weapons Ban (FAWB) on the number of public mass shooting events in the United States. This study provides an updated assessment with 3 additional years of firearm surveillance data to characterize the longer-term effects. This study aims to estimate the impact of the FAWB on trends in public mass shootings from 1966 to 2022. We used linear regression to estimate the impact of the FAWB on the 4-year simple moving average of annual public mass shootings, defined by events with 4 or more deaths in 24 hours, not including the perpetrator. The study period spans 1966 to 2022. The model includes indicator variables for both the FAWB period (1995-2004) and the period after its removal (2005-2022). These indicators were interacted with a linear time trend. Estimates were controlled for the national homicide rate. After estimation, the model provided counterfactual estimates of public mass shootings if the FAWB was never imposed and if the FAWB remained in place. The overall upward trajectory in the number of public mass shootings substantially fell while the FAWB was in place. These trends are specific to events in which the perpetrator used an assault weapon or large-capacity magazine. Point estimates suggest the FAWB prevented up to 5 public mass shootings while the ban was active. A continuation of the FAWB and large-capacity magazine ban would have prevented up to 38 public mass shootings, but the CIs become wider as time moves further away from the period of the FAWB. The FAWB, which included a ban on large-capacity magazines, was associated with fewer public mass shooting events, fatalities, and nonfatal gun injuries. Gun control legislation is an important public health tool in the prevention of public mass shootings.

Clinical Profile and Outcome of Ocular Shotgun Pellet Injury Over 13 Years

Background: Ocular trauma is a major preventable cause of visual morbidity and a leading cause of monocular blindness. Pellet injury is one of the causes of major ocular trauma. It needs extensive medical care and vocational rehabilitation. It has significant impact on global health Methods: This retrospective study was conducted from medical records of 25 patients with ocular pellet gun injury admitted in National Institute of Ophthalmology and hospital, Dhaka from 2011 to 2023. Results: Out of the 25 patients, 13 (52.0%) were more than 25 years age group while the mean age of the patients was 25.5 (±4.6) years. All of the patients were male. Among them 23 (92.0%) had unilateral eye involvement. Pellets caused perforating injuries in 12 (44.4%) eyes while in 9 (33.3%) eyes had closed globe injury. Vitreous hemorrhage in 21 (77.8%) eyes, retinal hemorrhage in 16 (59.3%) eyes, retinal tear in 15 (55.6%) eyes, while few (7.4%) had macular injury and 4 (14.8%) eyes suffered from traumatic optic neuropathy Majority of the eyes (15;55.6%) underwent PPV while 12 (44.4%) eyes were managed by conservative management. At baseline, only one eye (3.7%) had visual acuity 6/60 or better. Sixteen eyes (59.3%) had visual acuity <1/60 and 8 eyes (29.6%) had NPL. Six months after treatment, two eyes (7.4%) had visual acuity 6/60 or better. Visual acuity was <1/60 in 7 eyes (25.9%) while 17 eyes (63.0%) had NPL. Finally, sixteen eyes (59.3%) developed phthisis bulbi while 3 (11.1%) eyes were normal. Conclusion: This study highlights the bad impact of pellet injury to the society due to poor visual and anatomical outcomes despite of immediate surgical intervention. Protective eyewear should be used during wartime and protests and decision makers should ban use of pellet gun on the civilians.

Captive Bolt Gun-Related Vascular Injury: A Single Center Experience.

This article investigates the clinical and radiological characteristics of captive bolt gun head injuries, a rare form of low-velocity penetrating brain injury. Eleven consecutive patients were included in the study. Vascular injuries and the rate of infection were systematically analyzed. Radiological findings reveal common bolt trajectories in the anterior cranial fossa, with identified risk factors for a poor outcome including trajectory crossing midline, hematocephalus, and paranasal sinus involvement. Only one patient had a good outcome. Despite meticulous microsurgical techniques, this study highlights often unfavorable clinical outcomes in captive bolt gun injuries, with vascular injury identified as a potential contributing risk factor for a poor outcome. Knowledge of variant vascular tree anatomy and corresponding vascular territory is important. To avoid potential vascular injuries, a complete removal of bone fragments was not always performed and it did not increase the rate of infection, challenging the conventional wisdom advocating for the complete removal of bone fragments. These findings contribute novel insights into captive bolt gun-related injuries, paving the way for further research.

Ghost guns and crime: a tale of two California cities

BackgroundPrivately made firearms (PMFs) or “ghost guns” are homemade, unserialized, untraceable firearms that have been increasingly used in violent crime in the United States. Very little is known about the types of PMFs recovered by law enforcement agencies and the crimes associated with these recoveries. This lack of information limits effective violence prevention policies and practices. Comparative analysis of PMF recoveries in specific cities helps clarify whether local PMF patterns and characteristics vary or reflect more general trends. This research advances epidemiological understanding of emergent violent gun injury prevention challenges by identifying variations in recovered PMF types and use in violent, drug, and weapon-related offenses in Los Angeles and San Diego, California.MethodsConjunctive analysis of case configurations (CACC) identifies patterns among observations (i.e., case configurations) and calculates their probability associated with a given outcome. CACC was used to identify the most common types of PMFs recovered by the Los Angeles (LAPD) and San Diego (SDPD) police departments. For each department and offense type, case configurations with above-average probabilities of offense involvement were determined. Comparisons across departments were made to identify similarities and differences in PMF characteristics and usage.ResultsPMFs were more likely to be involved in violent and weapon-related offenses in Los Angles but more likely to be involved in drug-related offenses in San Diego. In both cities, the 9 mm Polymer 80 handgun was the dominant PMF. However, 9 mm handguns were most likely to be involved in weapon-related offenses in Los Angeles compared to 0.40 handguns in San Diego. Furthermore, large-caliber handguns tended to display above-average probabilities of involvement in violent and drug offenses in Los Angeles. Long guns were represented in case configurations with above-average probabilities of involvement in substantive crimes, including violence.ConclusionsComparative analyses of PMF recovery patterns in Los Angeles and San Diego reveal meaningful contextual variations in PMF characteristics and suggest intentional firearm type selections by offenders. The results support increased regulation of PMFs and highlight the importance of efforts to identify and disrupt the illicit supply of large-caliber PMF handguns and PMF long guns.

Gun violence revictimization in New York State: What increases the risk of being shot again?

While gun injuries are more likely to occur in urban settings and affect people of color, factors associated with gun violence revictimization-suffering multiple incidents of gun violence-are unknown. We examined victim demographics and environmental factors associated with gun violence revictimization in New York State (NYS). The 2005 to 2020 NYS hospital discharge database was queried for patients aged 12 years to 65 years with firearm-related hospital encounters. Patient and environmental variables were extracted. Patient home zip code was used to determine the Social Deprivation Index (SDI) for each patient's area of residence. We conducted bivariate and multivariate analyses among patients who suffered a single incident of gun violence or gun violence revictimization. We identified 38,974 gun violence victims among whom 2,243 (5.8%) suffered revictimization. The proportion of revictimization rose from 4% in 2008 to 8% in 2020 ( p < 0.01). The median [interquartile range] time from first to second incident among those who suffered revictimization was 359 days [81-1,167 days]. Revictimization was more common among Blacks (75.0% vs. 65.1%, p < 0.01), patients with Medicaid (54.9% vs. 43.2%, p < 0.01), and in areas of higher deprivation (84.8 percentile vs. 82.1 percentile, p < 0.01). Gun violence revictimization is on the rise. People of color and those residing in areas with high social deprivation are more likely to be re-injured. Our findings emphasize the importance of community-level over individual-level interventions for prevention of gun violence revictimization. Prognostic and Epidemiological; Level IV.

Interstate Highway Connections and Traced Gun Transfers Between the 48 Contiguous United States

Interstate gun flow has critical implications for gun violence prevention, as gun transfers across state lines can undermine local gun control policies. To identify possible gun trafficking routes along interstate highways in the US. This repeated-measures, ecological, cross-sectional study used data from the Bureau of Alcohol, Tobacco, Firearms and Explosives from January 1, 2010, to December 31, 2019, to examine associations between interstate connections via 13 highways that each spanned at least 1000 miles and interstate traced gun transfer counts for the 48 contiguous United States. Analyses were completed in November 2023. Characteristics of the origin states and the transportation connections between the destination state and the origin states. The main outcome was the total count of guns used in crimes in each destination state per year that were originally purchased in the origin state. Bayesian conditional autoregressive Poisson models were used to examine associations between the count of guns used in crime traced to interstate purchases and interstate highway connections between origin and destination states. Between 2010 and 2019, 526 801 guns used in crimes in the contiguous 48 states were traced to interstate purchases. Northbound gun transfers along the Interstate 95 corridor were greater than expected to New Jersey (incidence rate ratio [IRR], 2.80; 95% credible interval [CrI], 1.01-7.68) and Maryland (IRR, 3.07; 95% CrI, 1.09-8.61); transfers were similarly greater along Interstate 15 southbound, Interstate 25 southbound, Interstate 35 southbound, Interstate 75 northbound and southbound, Interstate 10 westbound, and Interstate 20 eastbound and westbound. This repeated-measures, ecological, cross-sectional study identified that guns used in crimes traced to interstate purchases moved routinely between states along multiple major transportation routes. Interstate gun transfers are a major contributor to gun crime, injury, and death in the US. National policies and interstate cooperation are needed to address this issue.

School Shootings in the United States: 1997-2022.

Gun violence in the United States is a public health crisis. In 2019, gun injury became the leading cause of death among children aged birth to 19 years. Moreover, the United States has had 57 times as many school shootings as all other major industrialized nations combined. The purpose of this study was to understand the frequency of school-related gun violence across a quarter century, considering both school shootings and school mass shootings. We drew on 2 publicly available datasets whose data allowed us to tabulate the frequency of school shootings and school mass shootings. The databases contain complementary data that provide a longitudinal, comprehensive view of school-related gun violence over the past quarter century. Across the 1997-1998 to 2021-2022 school years, there were 1453 school shootings. The most recent 5 school years reflected a substantially higher number of school shootings than the prior 20 years. In contrast, US school mass shootings have not increased, although school mass shootings have become more deadly. School shootings have risen in frequency in the recent 25 years and are now at their highest recorded levels. School mass shootings, although not necessarily increasing in frequency, have become more deadly. This leads to detrimental outcomes for all the nation's youth, not just those who experience school-related gun violence firsthand. School-based interventions can be used to address this public health crisis, and effective approaches such as Multi-Tiered Systems of Supports and services should be used in support of students' mental health and academic and behavioral needs.

Fasciotomy done for vascular trauma at a tertiary care centre in Sri Lanka

Introduction Compartment syndrome is a major factor contributing to limb loss and poor outcome following lower limb vascular injuries. Method This is a retrospective study done on patients with vascular injuries and undergone fasciotomy at the accident service operation theatre (ASOT) at the national hospital of Sri Lanka (NHSL), during a period of one year. Cases with Incomplete documentation were excluded. Data on patient demographics, time of injury, and time of fasciotomy, associated fractures, muscle viability and outcome were collected. Results A total of 30 cases were included. 26 (86%) were males. Nine (30%) were upper limb and 21(70%) were lower limb fasciotomy. The cause for limb injuries were road traffic accidents (RTA) in 18 (58.1%), trap gun injury in five (16.1%). All the fasciotomy were done prior to revascularization. 19 (63.3%) had fractures (12 (63%) were open and seven (36%) closed). six (20%) fasciotomy were done for compartment syndrome, 24 (80%) were done prophylactically. Three patients with compartment syndrome had open fractures (50%) and three had closed fractures (50%). On fasciotomy, in four cases all four leg compartment muscles were non-viable, two had non-viable three compartments and one patient had non-viable two compartments. The mean delay in patients who had all compartments viable was 3.7 hours (2-6.5) and the mean delay in patients with three or four non-viable compartments was 12.2hours (7-24). This difference was statistically significant (p-0.0001). The fasciotomy delay was also significant (p-0.0001) between the patients who had an amputation and limb salvage. Overall amputation rate was 20% in this series. Mean time of delay from admission to NHSL to the time of fasciotomy was 1.8 hours (1-3.5). Mean time of injury to time of fasciotomy was 5.42 hours (2-24). Discussion Number of non-viable compartments is significantly associated with the duration between time of injury to time of fasciotomy(P-0.0001). Therefore we suggest early fasciotomy before transfer

High-Pressure Paint Gun Injury of the Thumb: A Case of Reconstruction Using a Reverse Thenar Perforator-Based Island Flap

Hand injuries due to high-pressure paint gun devices are rare but may lead to serious outcomes. The authors describe a case of a high-pressure injury of the thumb that was managed promptly and later reconstructed successfully with minimal functional deficit. A 39-year-old man with a high-pressure paint gun injury of the right thumb was referred. Though the external wound was small, X-ray and computed tomography images showed extensive spread of paint inside. The paint was removed through a wide skin incision. After 6 weeks, the surgical wound had completely healed, except for a defect around the interphalangeal joint with bone exposure. A reverse thenar perforator-based island flap based on the princeps pollicis artery was elevated and moved to the defect. After defect reconstruction, the patient recovered pinch and grasp function through physiotherapy. High-pressure paint gun injuries of the thumb can lead to significant functional deficits of the hand. A small skin lesion may cause the actual extent of damage to be underestimated, as extensive penetration of paint can cause severe damage to the soft tissues. Thus, immediate surgical removal of the paint and coverage of the remnant wounds with an appropriate flap are necessary.

Low energy gunshot injuries: Does removal of retained bullet fragmentation at the time of internal fixation reduce the risk of fracture related infection?

ObjectiveTo examine the effects of RBF (Retained Bullet Fragment) removal at the time of long bone fixation on FRI (fracture related infection) rates in low energy GSI (Gunshot Injury) related fractures. DesignRetrospective Cohort Study SettingLevel 1 Academic Trauma Center InterventionRetrospective review of the impact of RBFs on the risk of FRI when employing internal fixation in low energy GSI (Gunshot Injury) related fractures. In situations where the injury pattern requires surgical fixation, the question arises as to whether or not the RBFs need to be removed to prevent FRI. Main outcome measuresWhether or not the RBFs removed in our patient population prevented short- and long-term fracture related infection after low-energy gunshot injury (FRI-LGI). ResultsOf the 2,136 GSI related fractures, 131 patients met inclusion criteria, 81 patients underwent removal (R) of RBFs at the time of internal fixation while 50 patients did not undergo any removal (NR) at time of internal fixation. Among the patients who underwent surgical intervention, (Open Reduction Internal Fixation) ORIF was performed in 55 cases (R: 39; NR: 16), and (Intramedullary Nail) IMN was performed in 76 cases (R: 42; NR: 34). The overall rate of deep FRI-LGI was 6.9 % of the 131-patient cohort. We found that removal of RBFs had a statistically significant impact on the rate of deep FRI-LGI when compared to the NR group (p = 0.031). In the RBF removal group, only two patients (2.4 %) developed deep FRI-LGIs, whereas in the NR group, seven patients (14.0 %) developed deep FRI-LGIs. The incidence of early FRI-LGI was higher in the NR group (median 0.6 months) compared to the R group, which was associated with late FRI-LGIs (median 10.1 months) when they occurred. DiscussionIn our study population, we found a statistically significantly increased incidence of deep and early FRI-LGI when RBFs are not removed at the time of extra-articular long bone internal fixation. The presence of retained bullet fragments following internal fixation may pose a risk factor for future development of deep FRI-LGI. We believe a surgeon should use their best judgment as to whether a RBF can safely be removed at the time of long bone fixation. Based on our findings, if safely permitted, RBF removal should be considered at the time of GSI long bone fixation resulting from low energy hand gun injuries.

Conversation starters: Understanding the facilitators and barriers to physician-initiated secure firearm storage conversations

ObjectiveThis paper aims to understand what general practice physicians (GPs) perceive as facilitators and barriers to initiating anticipatory guidance around firearm safety. MethodsWe employ qualitative interviewing to have in-depth conversations with 18 GPs. Participants were randomly selected from a national panel of physicians and screened for specialty (general practice or internist), practice setting (not hospital-based), and time spent on direct patient care (80% +). The sample was stratified at the state level by the presence of safe storage or child access protection laws, with half of the participants selected from each stratum. ResultsWe identify five physician-perceived barriers to providing secure firearm storage counseling, including inadequate screening mechanisms to trigger conversations, physician perceptions of who is at risk for firearm injury, time pressures, concerns about patient receptivity, and a need for training. ConclusionPrior to focusing on how to have conversations about firearm safety, interventions designed to increase the incidence of physician-initiated guidance need to address the structural issues of why those conversations typically do not occur. Practice implicationsFindings indicate the need for revised screening tools and improved physician education as to who is at risk for gun injury and how to best approach firearm safety conversations.

Targeting safety: Exploring trends and risk factors in pediatric head and neck BB gun injuries and hospitalization

ObjectiveTo examine head and neck injuries caused by BB (Ball Bearing) guns treated in US emergency departments among children under 18 to identify trends in injury frequency over time and risk factors associated with severe injuries leading to hospital admission. MethodsThis retrospective study utilized data from the National Electronic Injury Surveillance System (NEISS), a single database, to analyze head and neck injuries caused by BB guns between 1993 and 2019. The analysis explored demographic characteristics and injury patterns, including sex, age, incidence, injury location, hospital type, and disposition. Linear regression was employed to assess trends in the yearly frequency of injuries, while univariate and multivariate binary logistic regression was used to calculate the odds ratios associated with hospitalization. ResultsA total of 4041 cases of pediatric head and neck injuries caused by BB guns and treated in US emergency departments were identified. Most patients were male (84 %), with the highest proportion of injuries occurring in the 10–14 age group (49.7 %). The face (35.8 %) and eye (27.4 %) were the most affected injury sites, and 7.5 % of patients required hospital admission. No significant linear trend was observed in injury frequency over the study period. However, children aged four and under had higher odds of hospitalization (OR 2.77, 95 % CI 1.61–4.75) despite a lower incidence of injuries. Injuries to the eye (OR 12.37, 95 % CI 8.31–18.43) and neck (OR 7.58, 95 % CI 4.76–12.06) were strong predictors of hospital admission. ConclusionPediatric BB gun-related head and neck injuries remain a source of emergency room visits nationally. Younger children are at increased risk of admission to the hospital. Eye and neck injuries were the strongest predictors of hospital admission. Implementing safety precautions for younger children is crucial, as injuries might be more severe in this age group.

Preventable tragedies: findings from the #NotAnAccident index of unintentional shootings by children

BackgroundBetween 2015 and 2021, 3,498 Americans died from unintentional gun injuries, including 713 children 17 years and younger. Roughly 30 million American children live in homes with firearms, many of which are loaded and unlocked. This study assesses the scope of unintentional shootings by children 17 and younger in the US and the relationship between these shootings and state-level secure storage laws.MethodsDemographic and injury data of both perpetrators and victims of unintentional shootings by children 17 and younger in the US from 1/1/2015–12/31/2021 were extracted from the #NotAnAccident Index. The #NotAnAccident Index contains media-report data, which is systematically flagged through Google Alerts. We describe characteristics of incidents and examine incident rates over time. The association between state-level secure storage laws and rates of unintentional shootings by children is assessed in multivariate negative binomial regression models.Results2,448 unintentional shootings by children resulted in 926 deaths and 1,603 nonfatal gun injuries over a period of seven years. Most perpetrators (81%) and victims (76%) were male. The mean age was 10.0 (SD 5.5) for shooters and 10.9 (SD 8.1) for victims. Children were as likely to shoot themselves (49%) as they were to shoot others (47%). The majority of victims were under 18 years old (91%). Shootings most often occurred in or around homes (71%) and with handguns (53%). From March to December 2020, coinciding with the COVID-19 pandemic, incidents increased 24% over the same period in 2019, which was driven largely by an increase among shooters ages 0–5. Depending on the type of law, rates of unintentional shootings by children were 24% to 72% lower in states with secure storage laws, compared to states without such laws.ConclusionsUnintentional shootings by children are on the rise, particularly among children 0–5 years old, but are preventable tragedies. Our results show that secure firearm storage policies are strongly correlated with lower rates of unintentional shootings by children. Firearm storage policies, practices, and education efforts are needed to ensure guns are kept secured and inaccessible to children.

Multiple nail gun injuries: suicide or homicide?

Nail gun injuries are a forensic problem; it can be difficult to distinguish self-inflicted injuries from accident and homicide instances. This kind of injuries shares some characteristics with both gunshot and puncture wounds. We describe a peculiar case of a man who committed suicide driving nails into his skull using a pneumatic nail gun. Entrance wounds were found on both temporal regions of the head. Reviewing scientific literature, this is the first case in Italy reporting the macroscopic data of bilateral head and brain nail gun injuries during an autopsy. Circumstantial elements were not sufficient to clarify if these lesions were self-inflicted, inflicted by accident, or else. Radiological examination can be helpful to show the exact location of the nails, but it has also its own limitations. We firmly believe that autopsy, especially the head section, is crucial to identify the nature and the extension of these lesions, thus giving us much more information about the mechanism of death and the circumstances in which it occurred.
