Manejo cirúrgico de ferimento auto-infligido por arma de fogo em região maxilofacial / Surgical management of self-inflicted injury by gun in the maxillofacial region

INTRODUÇÃO: O manejo dos pacientes vítimas de PAF possui vertentes divergentes a respeito do tratamento cirúrgico, que pode ser realizado de forma imedata ou tardia. Em lesões auto-infligidas, a distância entre a arma e a região acometida é menor, causando consequências estéticas e funcionais mais devastadoras. Aliado ao fato desse tipo de trauma criar uma ferida suja devido à comunicação com a cavidade oral e seios paranasais, o manejo das lesões representam um desafio mesmo à cirurgiões experientes. OBJETIVO: Estre trabalho relata o manejo cirúrgico de uma ferida auto-infligida por arma de fogo que resultou em avulsão dos tecidos moles na região maxilofacial. DESCRIÇÃO DO CASO: Paciente do sexo masculino, 35 anos, vítima de projétil de arma de fogo auto-infligido em região maxilofacial, cursando com extenso ferimento em região de língua e mento. Clinicamente, o paciente não apresentava sinais de fratura em ossos da face. Ambos os ferimentos apresentavam secreção purulenta e o paciente manifestava disfonia devido a grande destruição tecidual. CONSIDERAÇÕES FINAIS: O tratamento de ferimentos por arma de fogo não só é um grande desafio para o cirurgião, como para toda a equipe multidisciplinar requerida para tais casos, visto que não há protocolos bem definidos para o tratamento dessas lesões(AU)

INTRODUCTION: The management of patients who are victims of FAP has divergent aspects regarding surgical treatment, which can be performed immediately or late. In self-inflicted injuries, the distance between the weapon and the affected region is smaller, causing more devastating aesthetic and functional consequences. Allied to the fact that this type of trauma creates a dirty wound due to the communication with the oral cavity and paranasal sinuses, the management of injuries represents a challenge even for experienced surgeons. OBJECTIVE: This paper reports the surgical management of a self-inflicted gunshot wound that resulted in soft tissue avulsion in the maxillofacial region. CASE DESCRIPTION: Male patient, 35 years old, victim of a self-inflicted firearm projectile in the maxillofacial region, coursing with extensive injury in the region of the tongue and chin. Clinically, the patient did not show signs of facial bone fractures. Both wounds had purulent secretion and the patient had dysphonia due to extensive tissue destruction. FINAL CONSIDERATIONS: The treatment of gunshot wounds is not only a great challenge for the surgeon, but also for the entire multidisciplinary team required for such cases, since there are no well-defined protocols for the treatment of these injuries(AU)

Diagnostic and therapeutic considerations in cases of civilian intravascular ballistic embolism: a review of case reports.

Background: Ballistic embolism (BE) is a rare complication of firearm injuries notoriously associated with a vexing clinical picture in the trauma bay. Unless considered early, the associated confusion can lead to needless delay in the management of the patient with a gunshot wound. Despite this known entity, there is a relative paucity of high-grade evidence regarding complications, management, and follow-up in these patients. Methods: An electronic database literature search was conducted to identify cases of acute intravascular BE in pediatric and adult civilians occurring during index hospitalization, filtered to publications during the past 10 years. Exclusion criteria included non-vascular embolization, injuries occurring in the military setting, and delayed migration defined as occurring after discharge from the index hospitalization. Results: A total of 136 cases were analyzed. Nearly all cases of BE occurred within 48 hours of presentation. Compared with venous emboli, arterial emboli were significantly more likely to be symptomatic (71% vs. 7%, p<0.001), and 43% of patients developed symptoms attributable to BE in the trauma bay. In addition, arterial emboli were significantly less likely to be managed non-invasively (19% vs. 49%, p<0.001). Open retrieval was significantly more likely to be successful compared with endovascular attempts (91% vs. 29%, p<0.001). Patients with arterial emboli were more likely to receive follow-up (52% vs. 39%) and any attempt at retrieval during the hospitalization was significantly associated with outpatient follow-up (p=0.034). All but one patient remained stable or had clinically improved symptoms after discharge. Conclusion: Consideration for BE is reasonable in any patient with new or persistent unexplained signs or symptoms, especially during the first 48 hours after a penetrating firearm injury. Although venous BE can often be safely observed, arterial BE generally necessitates urgent retrieval. Patients who are managed non-invasively may benefit from follow-up in the first year after injury.

Venovenous Extracorporeal Membrane Oxygenation Usage Following Bullet Embolism to the Pulmonary Artery.

Background: Pulmonary artery embolus is a rare complication following gunshot wounds that creates a unique and serious challenge for trauma surgeons. While the majority of bullets that embolize through the vascular system end in the peripheral circulation, approximately one-third enter the central venous circulation. Case Report: We present the case of a bullet embolus to the left pulmonary artery following gunshot wounds to the right chest and the abdomen, with the abdominal ballistic traversing the liver before entering the vena cava and embolizing. The patient's course was complicated by the development of severe acute respiratory distress syndrome that was successfully managed by venovenous extracorporeal membrane oxygenation. Conclusion: Venovenous extracorporeal membrane oxygenation support for severe acute respiratory distress syndrome after bullet embolization to the pulmonary tree and surgical embolectomy is a viable option in appropriately selected patients.

Improved follow-up care for gun violence survivors in the Trauma Quality of Life Clinic.

Background: Outpatient follow-up represents a crucial opportunity to re-engage with gun violence survivors (GVS) and to facilitate positive health outcomes. Current outpatient models for firearm-related injuries and trauma care are inconsistent and unstandardized across trauma centers. This project describes the patient population served by the multidisciplinary Trauma Quality of Life (TQoL) Clinic for GVS. Also of primary interest was the outpatient follow-up services used by patients prior to their clinic appointment. Subsequent referrals placed during Clinic, as well as rate of attendance, was a secondary aim. Methods: This was a descriptive retrospective analysis of a quality improvement project of the TQoL Clinic. Data were extracted from the electronic medical record and were supplemented with information from the trauma registry and the hospital-based violence intervention program database. Descriptive statistics characterized the patient population served. A Χ2 analysis was used to compare no-show rates for the TQoL Clinic against two historical cohorts of trauma clinic attendees. Results: Most attendees were young (M=32.0, SD=1.8, range=15-88 years), Black (80.1%), and male (82.0%). Of the 306 total TQoL Clinic attendees, 82.3% attended their initial scheduled appointment. Most non-attendee patients rescheduled their appointments (92.1%), and 89.5% attended the rescheduled appointment. TQoL Clinic demonstrated a significantly lower no-show rate than the traditional trauma clinic model, including after the implementation of the hospital's inpatient violence intervention program (χ2(2)=75.52, p<0.001). Conclusion: The TQoL Clinic has demonstrated improved outpatient follow-up to address the comprehensive needs of GVS. Trauma centers with high gunshot wound volume should consider the implementation of the multidisciplinary TQoL Clinic model to increase access to care and to continue partnership with violence intervention programs to address health outcomes in those most at risk of future morbidity and mortality. Level of evidence: Therapeutic/care management, level III.

Failure after operative repair is higher for ballistic femoral neck fractures than for closed, blunt-injury fractures: a multicenter retrospective cohort study.

Introduction: The purpose of this study was to describe the outcomes after operative repair of ballistic femoral neck fractures. To better highlight the devastating nature of these injuries, we compared a cohort of ballistic femoral neck fractures to a cohort of young, closed, blunt-injury femoral neck fractures treated with open reduction and internal fixation (ORIF). Methods: Retrospective chart review identified all patients presenting with ballistic femoral neck fractures treated at three academic trauma centers between January 2016 and December 2021, as well as patients aged ≤50 with closed, blunt-injury femoral neck fractures who received ORIF. The primary outcome was failure of ORIF, which includes the diagnosis of non-union, avascular necrosis, conversion to total hip arthroplasty, and conversion to Girdlestone procedure. Additional outcomes included deep infection, postoperative osteoarthritis, and ambulatory status at last follow-up. Results: Fourteen ballistic femoral neck fractures and 29 closed blunt injury fractures were identified. Of the ballistic fractures, 7 (50%) patients had a minimum of 1-year follow-up or met the failure criteria. Of the closed fractures, 16 (55%) patients had a minimum of 1-year follow-up or met the failure criteria. Median follow-up was 21 months. 58% of patients with ballistic fractures were active tobacco users. Five of 7 (71%) ballistic fractures failed, all of which involved non-union, whereas 8 of 16 (50%) closed fractures failed (p=0.340). No outcomes were significantly different between cohorts. Conclusion: Our results demonstrate that ballistic femoral neck fractures are associated with high rates of non-union. Large-scale multicenter studies are necessary to better determine optimal treatment techniques for these fractures. Level of evidence: Level III. Retrospective cohort study.

Fragmenting projectiles: a case report and literature review of the G2 Radically Invasive Projectile.

Innovations in projectile design present unique challenges for trauma surgeons when treating gunshot victims. The G2 Radically Invasive Projectile (G2 Research, Winder, Georgia, USA) (G2RIP) is a frangible, rapidly expanding bullet resulting in a distinct pattern of injury consisting of diffuse hemorrhage with multicavity trauma as well as unique radiographic features of the projectile. To efficiently manage patients injured by the G2RIP, trauma surgeons must be aware of these distinct characteristics, and of previous patterns in effective management such as liberal damage control and extensive use of CT. Understanding previous presentation and management of patients injured by the G2RIP can aid in improving patient care in the trauma center.

Impact of gun violence.

In our societal focus on gun mortality, we lose sight of the long-term effects of these injuries, including the cost and treatment burden that victims and their families incur and, in fact, the nation at large. Measuring the impact of gun violence by mortality rate alone is a gross underestimation of its true impact. While the debate on how to reduce rate of gun violence continues, it is imperative that we make every endeavor to ensure that victims of gun violence receive the care they need to reduce disability and morbidity. It is crucial that we prevent firearm-related deaths, and we must address the sequelae of these injuries and the casualties that these injuries bring the opportunities and livelihoods of the survivors of gun violence.

Firearms-related injury and sex: a comparative National Trauma Database (NTDB) Study.

Background: Existing study findings on firearms-related injury patterns are largely skewed towards males, who comprise the majority of this injury population. Given the paucity of existing data for females with these injuries, we aimed to elucidate the demographics, injury patterns, and outcomes of firearms-related injury in females compared with males in the USA. Materials and methods: A 7-year (2013-2019) retrospective review of the National Trauma Database was conducted to identify all adult patients who suffered firearms-related injuries. Patients who were males were matched (1:1, caliper 0.2) to patients who were females by demographics, comorbidities, injury patterns and severity, and payment method, to compare differences in mortality and several other post-injury outcomes. Results: There were 196 696 patients admitted after firearms-related injury during the study period. Of these patients, 23 379 (11.9%) were females, 23 378 of whom were successfully matched to a male counterpart. After matching, females had a lower rate of in-hospital mortality (18.6% vs. 20.0%, p<0.001), deep vein thrombosis (1.2% vs. 1.5%, p=0.014), and had a lower incidence of drug or alcohol withdrawal syndrome (0.2% vs. 0.5%, p<0.001) compared with males. Conclusion: Female victims of firearms-related injuries experience lower rates of mortality and complications compared with males. Further studies are needed to elucidate the cause of these differences. Level of evidence: Level III.

Implementation of an emerging hospital-based violence intervention program: a multimethod study.

Background: Individuals who experience assaultive firearm injury are at elevated risk for violent reinjury and multiple negative physical and psychological health outcomes. Hospital-based violence intervention programs (HVIPs) may improve patient outcomes through intensive, community-based case management. Methods: We conducted a multimethod evaluation of an emerging HVIP at a large trauma center using the RE-AIM framework. We assessed recruitment, violent reinjury outcomes, and service provision from 2020 to 2022. Semistructured, qualitative interviews were performed with HVIP participants and program administrators to elicit experiences with HVIP services. Directed content analysis was used to generate and organize codes from the data. We also conducted clinician surveys to assess awareness and referral patterns. Results: Of the 319 HVIP-eligible individuals who presented with non-fatal assaultive firearm injury, 39 individuals (12%) were enrolled in the HVIP. Inpatient admission was independently associated with HVIP enrollment (OR 2.6, 95% CI 1.3 to 5.2; p=0.01). Facilitators of Reach included engaging with credible messengers, personal relationships with HVIP program administrators, and encouragement from family to enroll. Fear of disclosure to police was cited as a key barrier to enrollment. For the Effectiveness domain, enrollment was not associated with reinjury (OR 0.70, 95% CI 0.16 to 3.1). Participants identified key areas of focus where needs were not met including housing and mental health. Limited awareness of HVIP services was a barrier to Adoption. Participants described strengths of Implementation, highlighting the deep relationships built between clients and administrators. For the long-term Maintenance of the program, both clinicians and HVIP clients reported that there is a need for HVIP services for individuals who experience violent injury. Conclusions: Credible messengers facilitate engagement with potential participants, whereas concerns around police involvement is an important barrier. Inpatient admission provides an opportunity to engage patients and may facilitate recruitment. HVIPs may benefit from increased program intensity. Level of evidence: IV.

Heridas de guerra en el Perú del siglo XIX: la lesión ocular de Andrés Avelino Cáceres / War wounds in nineteenth century Peru: the eye injury of Andrés Avelino Cáceres

RESUMEN Andrés Avelino Cáceres (1836-1923) fue un destacado político y militar peruano que ocupó la presidencia en dos periodos y lideró al ejército peruano durante la Guerra del Pacífico, por lo que es considerado un héroe nacional. Al inicio de su carrera militar, durante el sitio a la ciudad de Arequipa en 1858, sufrió una lesión ocular cuya cicatriz se observa en las fotografías que se le tomaron posteriormente a lo largo de su vida, lo que hizo que fuera apodado "El Tuerto" aunque al parecer su agudeza visual estuvo indemne. En este trabajo describiremos las circunstancias en las que se produjo la lesión oftálmica de Andrés Avelino Cáceres, las secuelas que pudo tener este traumatismo oftálmico y el tratamiento médico que pudo haber recibido, en base al propio relato del héroe y a las imágenes suyas que se conservan.

ABSTRACT Andrés Avelino Cáceres (1836-1923) was a prominent Peruvian politician and military man who held the presidency for two terms and led the Peruvian army during the Pacific War, for which he is considered a national hero. At the beginning of his military career, during the siege of the city of Arequipa in 1856, he suffered an eye injury whose scar can be seen in the photographs that were taken of him later throughout his life, which led to him being nicknamed "El Tuerto". We will describe the circumstances in which the ophthalmic injury of Andrés Avelino Cáceres occurred, the consequences that this ophthalmic trauma could have had and the treatment he could have received, based on the hero's own story and the images of him that are preserved.

Variability in firearm injury among major pediatric trauma centers across the USA.

Objectives: In 2020, firearm injuries surpassed automobile collisions as the leading cause of death in US children. Annual automobile fatalities have decreased during 40 years through a multipronged approach. To develop similarly targeted public health interventions to reduce firearm fatalities, there is a critical need to first characterize firearm injuries and their outcomes at a granular level. We sought to compare firearm injuries, outcomes, and types of shooters at trauma centers in four pediatric health systems across the USA. Methods: We retrospectively extracted data from each institution's trauma registry, paper and electronic health records. Study included all patients less than 19 years of age with a firearm injury between 2003 and 2018. Variables collected included demographics, intent, resources used, and emergency department and hospital disposition. Descriptive statistics were reported using medians and IQRs for continuous data and counts with percentages for categorical data. χ2 test or Fisher's exact test was conducted for categorical comparisons. Results: Our cohort (n=1008, median age 14 years) was predominantly black and male. During the study period, there was an overall increase in firearm injuries, driven primarily by increases in the South (S) site (ß=0.11 (SE 0.02), p=<0.001) in the setting of stable rates in the West and decreasing rates in the Northeast and Mid-Atlantic sites (ß=-0.15 (SE 0.04), p=0.002; ß=-0.19 (SE0.04), p=0.001). Child age, race, insurance type, resource use, injury type, and shooter type all varied by regional site. Conclusion: The incidence of firearm-related injuries seen at four sites during 15 years varied by site and region. The overall increase in firearm injuries was predominantly driven by the S site, where injuries were more often unintentional. This highlights the need for region-specific data to allow for the development of targeted interventions to impact the burden of injury.Level of Evidence: II, retrospective study.

Spinal fractures and thoracoabdominal injuries in polytraumatized patients: epidemiological evaluation / Fraturas da coluna vertebral e lesões toracoabdominais em pacientes politraumatizados: avaliação epidemiológica / Fracturas vertebrales y lesiones toracoabdominales en pacientes politraumatizados: evaluación epidemiológica

ABSTRACT Objective: Establish the frequency of incidences, management, and description of the relationship between thoracic and abdominal trauma and spinal injury. Methods: Observational, retrospective study of quantitative analysis carried out through the analysis of medical records of patients who presented spinal fractures and associated thoracoabdominal injuries. The participants were treated at a reference hospital in trauma care in Curitiba-PR from 2019 to 2021. The data were from patients with spine fractures referring to gender, age, trauma mechanism, fracture classification, associated injuries, Frankel neurological scale, and proposed treatment. Results: There was a predominance of male patients (84.5%) and young, with a mean age of 37.3 years, victims of car accidents. The main vertebrae affected were the lumbar spine (36.8%) and thoracic spine (36.2%). The most prevalent associated injuries were extra vertebral and cervical spine fractures. The most observed thoracic injuries were hemothorax, chest contusion, and fracture of multiple costal arches, while the most observed abdominal injuries were kidney injury, hemoperitoneum/abdominal hematoma, and liver injury. Of the total patients analyzed, 68% had fractures with associated thoracoabdominal injuries. Conclusion: Abdominal and thoracic injuries are frequently associated with spine fractures, with an association of 14.6% and 53.4%, respectively. The production of knowledge on the subject contributes to creating action plans to optimize the management and reduce the morbidity and mortality of these cases.

Language of violence: Do words matter more than we think?

Firearm violence is a leading cause of morbidity and mortality among young adults. Identification of intervention targets is crucial to developing and implementing effective prevention efforts. Hospital Violence Intervention Programs (HVIPs) have used a multiprong social care approach to mediate the cycle of interpersonal violence. One struggle continually encountered is how to change the conversation around the future. Speech patterns have been associated with health outcomes and overall behavior modification. During violence prevention efforts, young victims of violence say things such as 'I'm living on borrowed time' and 'why should I worry about getting an education when I'll likely die soon anyway?' Such speech patterns may contribute to the cycle of violence and increase the likelihood of reinjury. Presented is a narrative review of the impact language has on health outcomes and how psychotherapy may be able to change thought patterns, alter language structure, and ultimately reduce risk of reinjury. The biopsychosocial model of health posits that a person's health is dictated by a combination of biological, psychological, and social factors. By understanding that language exists in the personal context, it can serve as both an indicator and a tool for targeted interventions. Cognitive-behavioral therapy (CBT) works by retraining thought and speech patterns to affect change in emotion, physiology, and behavior. It is proposed here that CBT could be used in the HVIPs' multidisciplinary case management model by involving trained psychotherapists. Language is an important indicator of a patient's psychological state and approach to life-changing decisions. As such, language alteration through CBT could potentially be used as a novel method of injury prevention. This concept has not before been explored in this setting and may be an effective supplement to HVIPs' success.

Gunshot Wounds to the Lumbosacral Spine: Systematic Review and Meta-Analysis.

STUDY DESIGN: Systematic review and meta-analysis. OBJECTIVES: Indications for surgical decompression of gunshot wounds to the lumbosacral spine are controversial and based on limited data. METHODS: A systematic review of literature was conducted to identify studies that directly compare neurologic outcomes following operative and non-operative management of gunshot wounds to the lumbosacral spine. Studies were evaluated for degree of neurologic improvement, complications, and antibiotic usage. An odds ratio and 95% confidence interval were calculated for dichotomous outcomes which were then pooled by random-effects model meta-analysis. RESULTS: Five studies were included that met inclusion criteria. The total rate of neurologic improvement was 72.3% following surgical intervention and 61.7% following non-operative intervention. A random-effects model meta-analysis was carried out which failed to show a statistically significant difference in the rate of neurologic improvement between surgical and non-operative intervention (OR 1.07; 95% CI 0.45, 2.53; P = 0.88). In civilian only studies, a random-effects model meta-analysis failed to show a statistically significant difference in the rate of neurologic improvement between surgical and non-operative intervention (OR 0.75; 95% CI 0.21, 2.72; P = 0.66). Meta-analysis further failed to show a statistically significant difference in the rate of neurologic improvement between patients with either complete (OR 4.13; 95% CI 0.55, 30.80; P = 0.17) or incomplete (OR 0.38; 95% CI 0.10, 1.52; P = 0.17) neurologic injuries who underwent surgical and non-operative intervention. There were no significant differences in the number of infections and other complications between patients who underwent surgical and non-operative intervention. CONCLUSIONS: There were no statistically significant differences in the rate of neurologic improvement between those who underwent surgical or non-operative intervention. Further research is necessary to determine if surgical intervention for gunshot wounds to the lumbosacral spine, including in the case of retained bullet within the spinal canal, is efficacious.
