Penetrating chest injury secondary to an improvised home-made marble airgun: a case report.

Background: An improvised air gun with marble bullets, locally known as "Jolen Gun", is a type of home-made gun using Polyvinyl chloride (PVC) pipes and compressed air. It is mainly being used as a hunting tool in Central Mindanao. This "non-lethal" weapon has the potential in causing serious harm. There has been several incidents of minor injuries from this type of weapon in our institution but this is the first documented case of an improvised marble air-gun causing significant injury to the patient. Case report: A child was brought to a rural tertiary center after being shot in the chest using an improvised gun with marble as bullet. On evaluation, the patient had a single gunshot wound approximately 2cm x 2cm in size on the posterior chest at the right paravertebral area of the 4th thoracic vertebra. There was no exit wound noted. Chest CT done showed a rounded radiopaque foreign body seen in the right upper lung field with gunshot fracture involving the posterior aspect of the 4th rib. There was also pulmonary contusion of the right upper lobe and a fluid density at the right posterior pleural space attributed to a hemothorax. Open thoracotomy, removal of foreign body, repair of lung injury and debridement was done. Patient had an unremarkable post-operative course and was subsequently discharged. Conclusion: After extensive search of both local and international literatures, this appears to be the first case involving a penetrating chest injury from an improvised marble air-gun which has been treated successfully. Although this is a low-energy type of weapon, it still has the potential to cause significant harm to the body. Relevant laws should be made to against the use of this type of weapon to prevent similar injuries in the future.

Residual foreign body inflammation caused by a lumber beam penetrating the facial region: a case report.

Penetrating wounds to the face are cosmetically devastating and can be life-threatening. If the foreign body causing the penetrating wound is a piece of wood, small remnants might be left behind after the initial treatment. A 33-year-old male patient presented to the emergency center after a piece of lumber pierced his face as a passenger in a traffic accident. The patient's vital signs were stable, and emergency surgery was performed to remove the foreign body and repair the soft tissue. No noteworthy complications were seen after open reduction and internal fixation of the facial bone fractures. Seven months after the accident, the patient underwent scar revision along with full-thickness skin grafting for post-traumatic scars. After the surgery, pus-like discharge which was not previously present was observed, and the graft did not take well. A residual foreign body, which was the cause of graft failure, was found on computed tomography and the remaining foreign body was removed through revision surgery. The patient is receiving outpatient follow-up without any complications 6 months after surgery. This case demonstrates the importance of performing a careful evaluation to avoid missing a residual foreign body, especially if it is of wooden nature.

Penetrating Neck Injury Involving Wooden Foreign Bodies: Case Report.

Although rare, penetrating neck injuries can have grave consequences, and are associated with high mortality rates. Individuals with cervical injuries due to wooden foreign bodies are at an increased risk of developing infectious complications. In this case, a male patient aged 27 years presented with a cervical injury indicative of a penetrating wound caused by a wooden foreign body. Computed tomography (CT) scan revealed no signs of intracranial hemorrhage or fracture. Additionally, cervical CT scan showed no evidence of cervical corpus or longus colli muscle lesions. The medical team suggested a cervical magnetic resonance imaging (MRI) examination; however, the patient's family opted out. Subsequently, the patient underwent wound debridement, which involved the extraction of a fragment of impaling wood. Two days after the procedure, the patient developed a fever and weakness of the shoulder and arm on the ipsilateral side. Following the process of re-education, the family provided consent for MRI examination. A subsequent surgical procedure was performed on the patient based on the MRI findings and clinical presentation. Residual wooden fragments were effectively extracted, resulting in positive progression of the patient's condition.

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.

Suicidio por herida pérforo-cortante en el abdomen / Suicide by piercing-cutting wound to the abdomen

RESUMEN El suicidio es un problema humano que existe desde el origen mismo del hombre, ha sucedido en todas las épocas, ha afectado a ambos géneros y a diferentes clases sociales; varía sus características de acuerdo con la cultura y la estructura socio-económica. El uso de arma blanca como método suicida es relativamente poco común en el campo médico legal, por eso este tipo de casos es pobremente estudiado, lo que en ocasiones plantea variadas dificultades al momento de diferenciarlos de heridas producidas de manera homicida. Se presenta un individuo que falleció tras autoinfligirse heridas pérforo-cortantes en el abdomen, lo cual constituye un método poco común de suicidio en el contexto cubano.

ABSTRACT Suicide is a human problem that has existed since the very origin of man, it has happened at all times, and has affected both genders and different social classes; its characteristics vary according to culture and socio-economic structure. The use of edged weapons as a suicide method is relatively uncommon in the medical-legal field, that is why this type of case is poorly studied, because sometimes poses various difficulties when differentiating it from wounds produced in a homicidal manner. We present an individual who died after self-inflicted piercing-cutting abdominal stab wounds, which constitutes an uncommon method of suicide in the Cuban context.

Torso vascular trauma.

Vascular injury within the chest or abdomen represents a unique challenge to the pediatric general surgeon, as these life- or limb-threatening injuries are rare and may require emergent treatment. Vascular injury may present as life-threatening hemorrhage, or with critical ischemia from intimal injury, dissection, or thrombosis. Maintaining the skillset and requisite knowledge to address these injuries is of utmost importance for pediatric surgeons that care for injured children, particularly for surgeons practicing in freestanding children's hospitals that frequently do not have adult vascular surgery coverage. The purpose of this review is to provide an overview of torso vascular trauma, with a specific emphasis in rapid recognition of torso vascular injury as well as both open and endovascular management options. Specific injuries addressed include blunt and penetrating mediastinal vascular injury, subclavian injury, abdominal aortic and visceral segment injury, inferior vena cava injury, and pelvic vascular injury. Operative exposure, vascular repair techniques, and damage control options including preperitoneal packing for pelvic hemorrhage are discussed. The role and limitations of endovascular treatment of each of these injuries is discussed, including endovascular stent graft placement, angioembolization for pelvic hemorrhage, and resuscitative endovascular balloon occlusion of the aorta (REBOA) in children.

Manejo laparoscópico de hernia diafragmática traumática: reporte de un caso / Laparoscopic management of traumatic diaphragmatic hernia: a case report

La hernia diafragmática traumática representa un reto al momento del diagnóstico. Una detección oportuna permite establecer un correcto tratamiento quirúrgico. Se presenta el caso de un paciente masculino de 37 años de edad con antecedente de trauma torácico por arma blanca 4 años antes; quien acude por cuadro de dolor abdominal intenso localizado en epigastrio que se irradia a hipocondrio izquierdo de aparición súbita 72 horas antes de su ingreso. Al examen físico murmullo vesicular disminuido en campo pulmonar izquierdo, y abdomen doloroso a la palpación a nivel de epigastrio e hipocondrio izquierdo. En exámenes de laboratorio no se evidencian alteraciones, mientras que la tomografía reporta hernia diafragmática izquierda; la misma que fue resuelta quirúrgicamente mediante técnica laparoscópica.

Traumatic diaphragmatic hernia represents a challenge at diagnosis. A timely detection allows to establish a correct surgical treatment. It is presented the case of a 37-year-old male patient with a history of stabbing chest trauma 4 years earlier; who comes for symptoms of intense abdominal pain located in the epigastrium that radiates to the left hypochondrium of sudden onset 72 hours before admission. On physical xamination, vesicular murmur decreased in the left lung field, and a painful abdomen on palpation at the level of the epigastrium and left hypochondrium were showed. Laboratory tests did not show any alterations, but tomography reports a left diaphragmatic hernia; this one was solved surgically by laparoscopic technique.

Long-term intra-arterial shunt.

This is a case report of a patient who sustained a stab wound to the right axilla with injuries to the right axillary artery and vein. The patient had near-exsanguination in the field and no recordable blood pressure upon admission to the trauma center. Resuscitation was performed with endotracheal intubation, a left anterolateral resuscitative thoracotomy with cross-clamping of the descending thoracic aorta, and the rapid infusion of crystalloid solutions and packed red cells. In the operating room, the third portion of the right axillary artery and the adjacent right axillary vein were found to be transected. As part of a 'damage control' procedure, the ends of the right axillary vein were ligated. A 14 French intra-arterial shunt was inserted into the transected ends of the right axillary artery to restore the flow to the right upper extremity. The patient's postoperative course was complicated by a coagulopathy, adult respiratory distress syndrome (ARDS), and anuria. The coagulopathy and anuria resolved within the first 48 hours, but the patient's ARDS was slow to resolve. On the 10th postinjury day, the patient was returned to the operating room for a definitive repair of the right axillary artery. After the intra-arterial shunt was removed, a reversed greater saphenous vein graft was inserted between the ends of the right axillary artery in a medial intermuscular (extra-anatomic) tunnel. The patient made an uneventful recovery and was discharged home on the 16th postinjury day. The following principles of advanced trauma care were part of the management of this patient: (1) occasional need for resuscitative thoracotomy with cross-clamping of the descending thoracic aorta in a patient without a thoracic injury; (2) 'damage control' operation with ligation of the right axillary vein and placement of a temporary intra-arterial shunt to restore the flow to the right upper extremity; and (3) vascular reconstruction with an extra-anatomic bypass in a previously contaminated field.

ABSTRACT Objective: to analyze the sociodemographic profile, morbidity and mortality and spatial distribution of victims of firearms injuries attended by the mobile emergency care service. Methods: cross-sectional study of the care records of 603 firearm injury victims attended by the Mobile Emergency Care Service. Descriptive statistics, univariate association analysis and Kernel map were used for spatial distribution. Results: most of the victims were male (94%), aged between 21 and 30 years (61.5%). Most deaths (73.7%) occurred in this same age group. The spatial distribution showed the majority of victims in conurbated municipalities in the metropolitan region, with high morbidity and mortality. Conclusion: there was a higher prevalence of victims and deaths in men, aged 21 to 30 years, with head and neck injuries and multiple sites. In this sample it was not possible to establish a statistically significant relationship between the cities of the occurrences, but there are quite expressive focuses in the cities of Sarandi and Paiçandu. The results can provide input to formulate public policies for preventing violence and preparing for emergency care.

Management of a Penetrating Thoracic Injury with Thoracoscopy; A Case Study.

INTRODUCTION: Various strategies could be considered dealing with penetrating thoracic injuries. Thoracoscopy is much less invasive than routine thoracotomy approach for managing such cases in which the sharp object remains in the body. The case presented in this article was managed with thoracoscopy for a penetrating dorsolateral thoracic injury. CASE PRESENTATION: A 35-year-old man with a penetrating dorsolateral thoracic injury referred to the emergency department. Despite an elevated pulse rate, the patient has proper blood pressure and O2 saturation. Considering the patient's stability and the results of imaging which did not show any massive vascular injury, the patient was taken to the operation room for thoracoscopy. At thoracoscopy, we saw 4 cm of the blade in the thoracic cavity between the third and fourth intercostal space. There was a mild laceration of lung tissue without any active bleeding. Considering the position of the blade and the absence of active bleeding and vascular injury at the trauma site, we successfully removed the blade by the thoracoscope without any complications. CONCLUSION: Our experience of removing a retained knife by thoracoscopy showed that it can be an appropriate alternative for patients with penetrating thoracic injury who are hemodynamically stable and have appropriate conditions for thoracoscopy.

Penetrating Wounds of the Upper Extremity - Prevalence and Etiology.

Objective To define the major epidemiological features of upper limb penetrating injuries, as well as to identify the causes and the frequency of these lesions at the Instituto de Ortopedia e Traumatologia, a hand surgery center in the city of São Paulo, state of São Paulo, Brazil. Methods The present study was based on a sample of consecutive patients from our orthopedics and traumatology institute from May 2014 to May 2016. Data were collected by telephone, and a prestructured questionnaire regarding data and features of the lesions was applied. Descriptive statistics and proportions comparison with the chi-squared test were performed with a p -value < 5% considered as statistically significant. Results At first, 1,648 records were considered and, after applying the exclusion criteria and eliminating duplicate records, 598 records were included in the present study. Most of the patients were male (77.8%), right-handed (95.82%), with an average age of 37.27 years old. Manual laborers were the most injured individuals (50.00%), and fingers were the most affected site (51.84%). Glass was the most frequent etiologic agent (33.77%). The prevalence of amputation was higher in industrial machinery injuries ( p < 0.05) when compared with other causes. Younger patients (< 18 years old) had more glass-related injuries, while older patients (≥ 60 years old) had more traumas caused by power tools ( p < 0.05). Women had more injuries resulting from razors and glass ( p < 0.05). Manual laborers had a higher frequency of power tools and industrial machinery-related injuries ( p < 0.05) and a higher prevalence of amputations ( p < 0.05). Conclusion The most frequent etiology was glass, especially in individuals < 18 years old. Women and older patients (> 60 years old) presented a high frequency of traumas caused by razors and power tools, respectively. More severe injuries were caused by machinery and were related with work activity.

Long-term traumatic and asymptomatic aorto-right atrial fistula

Abstract Aorto-atrial fistulas due to cardiac trauma are rare, and survivors require immediate surgical correction. Here, we report a case of an aorto-right atrial fistula due to penetrating trauma after a 16-year evolution, which developed symptoms of acute coronary syndrome and was treated with myocardial revascularization and correction of the aorto-cameral fistula.
