Penetrating and orthopaedic trauma from blast versus gunshots caused by terrorism: Israel's National Experience

Impact of injury mechanism on early wound closure in patients with acute conflict-related extremity wounds: A prospective cohort analysis from two civilian hospitals in Iraq and Jordan

BACKGROUND

Gunshots and bomb blasts are important causes of extremity injuries in conflict zones, yet little research exists on the characteristics and outcomes of these injuries in civilian populations.

METHODS

We performed a prospective cohort analysis utilizing data from a randomized trial conducted at two civilian hospitals in Jordan and Iraq in 2015-2019. Adults who presented ≤72 h of sustaining an extremity injury were included. We used mechanism of injury (gunshot/bomb blast) as the exposure and wound closure by day 5 as the primary outcome measure.

RESULTS

The population predominantly comprised young men (n = 163, 94% male, and median age 29 years) injured by gunshots (61%) or bomb blasts (39%). Compared with the gunshot group, more participants in the bomb blast group had concomitant injuries (32/63 [51%] vs. 11/100 [11%], p < 0.001) and vascular injuries (9/63 [14%] vs. 4/100 [4%], p = 0.02). The wounds were larger in the bomb blast group compared with the gunshot group (median area 86 cm2 [IQR 24-161] vs. 21 cm2 [IQR 7-57], p < 0.001). Compared with the bomb blast group, significantly more participants in the gunshot group achieved wound closure by day 5 (74/100 [74%] vs. 16/63 [25%], p < 0.001). This difference remained after controlling for confounding factors (odds ratio 4.7, 95% confidence interval 1.6-13.7).

CONCLUSIONS

In civilians with conflict-related extremity injuries, bomb blast wounds had a lower likelihood of achieving closure within 5 days than gunshot wounds, independent of other factors, such as wound size and vascular injuries.

Patterns of War-Related Traumatic Brain Injuries and Predictors of Mortality Among Civilians During the Syrian Armed Conflict

BACKGROUND AND OBJECTIVES

High-velocity weapons were used against unshielded civilians during the Syrian armed conflict, leading to a variety of combat-related traumatic brain injuries with high fatality and morbidity. Because of the lack of data in the literature about the management and outcomes of similar injuries, we aimed in this study to characterize shrapnel and gunshot injuries in this vulnerable group and to describe the association between the mechanisms, site, and type of injury and the outcomes.

METHODS

This was a single-center retrospective cohort study on new traumatic brain injuries in civilians who presented alive to the neurosurgery department at Damascus Hospital between 2014 and 2017. The analyzed data included the mechanism of injury and its type and site based on computed tomography scans. We also studied the neurological status at admission, the major interventions applied, and outcomes including mortality and neurological deficits at discharge.

RESULTS

Shrapnel and gunshot injuries more likely affected the frontal and parietal lobes, respectively. While shrapnel led to injuries in multiple body parts, gunshots led to localized but more severe injuries. Despite that, mortality rates were comparable between the two mechanisms. Injuries to the right parietal and right frontal lobes were more fatal with odds ratios of 2.61 (1.23-5.52) and 2.12 (1.00-4.50), respectively. Moreover, mortality was also linked to the radiological findings of loss of brain material with an odds ratio of 3.73 (1.42-9.81), intracerebral hemorrhage with an odds ratio of 3.60 (1.67-7.80), intraventricular hemorrhage with an odds ratio of 5.49 (1.68-17.95), and subdural hemorrhage with an odds ratio of 6.35 (2.29-17.66).

CONCLUSION

The unfortunate nature of the Syrian armed conflict, wherein civilians were targeted during their daily routine, seems to manifest a heightened propensity to affect the parietal lobes, potentially resulting in higher morbidity. Although shrapnel and gunshot injuries showed no significant difference in mortality rates, injuries involving loss of brain tissue and intracranial hemorrhage emerged as independent predictors of mortality.

Epidemiological characteristics and comparative outcome of blast versus gunshot injuries of the extremities in Somalia

BACKGROUND

War conflicts and terror-related injuries constitute a significant public health problem in Somalia. We aim to characterize and compare the injury characteristics of gunshot and blast injuries of the extremities.

METHODS

The data of 333 patients with gunshot and blast injuries of the extremities over three years were retrospectively reviewed. The demographics, injury characteristics, and outcomes were analyzed.

RESULTS

Most of the patients had injuries due to gunshot casualties compared with blast victims (n = 222, 66.7% vs. n = 111, 33.3%). Patients with gunshot wounds (GSW) had a more significant proportion of males than those with blast wounds (BW) (95.5% vs. 85.6%, P < 0.001). There were more open extremity fractures in GSW casualties (96.4% vs. 81.1%). The BW victims had significantly higher associated injuries (52.3% vs. 18.5%, P < 0.001). The BW group had a higher injury severity score (ISS ≥ 16 in 55%, P < 0.001). The need for an intensive care unit (ICU) admission was significantly higher in the BW patients (18% vs. 6.3%, P < 0.001); as well as the length of hospital stay (LOS) was higher in the BW group compared with the GW patients (> 2-week hospital stay in 31% vs. 19%, P < 0.04). About a 2.7% mortality rate was observed in BW (P < 0.014).

CONCLUSION

Gunshot and explosion injuries comprise the majority of war and terror-related trauma of the extremities. These injury mechanisms differ in the body regions involved, the severity of the injury, duration of hospital stay, need for ICU admission, and mortality. Assessment and management of such devastating casualties require a complex and multidisciplinary approach.

Gunshot casualties in Israel: A decade of violence

OBJECTIVE

The purpose of this study was to identify and characterize casualties hospitalized with assault (non-terror) related gunshot wounds (GSW) in Israel as a basis for determining the incidence, trends and at-risk population groups.

METHODS

This retrospective cohort study is based on data from the Israel National Trauma Registry. The data includes GSW casualties hospitalized between January 1, 2011 and December 31, 2020. Attempted suicide, unintentional injury, legal intervention, children (ages 0-9) and terror (Israeli-Arab conflict) related GSW were excluded. The remaining population was classified with an ICD-9-CM diagnosis code of 965.0-965.4.

RESULTS

The study population included 2,763 GSW admissions. A noticeable increase in GSW casualties was reported, from 206 hospitalization in 2011 to 456 in 2020. The proportion of Arab casualties increased from 73.3% of all GSW casualties in 2011 to 90.8% in 2020, far more than their proportion in the population (∼20%). The majority of the GSW casualties were males (95.8%) and between the ages of 20 and 29 (42.2%). Among severe/critical casualties, 19% of Arabs and 9.9% of Jews arrived by private car. Severe thoracic and abdominal injuries were the prominent injuries among fatal casualties (47.6 and 40.8, respectively). While the all-severity mortality rate was 5.6% (n = 147), 24.4% (n = 135) of severe/critical (ISS16+) casualties died, with no significant differences between Jews and Arabs. Forty percent of deaths occurred in the emergency department.

CONCLUSIONS

This study establishes that during the past decade in Israel, not only has there been a continuous increase in hospitalizations due to GSW, but also Arabs are at great risk of such related hospitalizations. Preventive strategies targeting at-risk groups are crucial for minimizing morbidity and mortality related to GSW in Israel.

Evaluation of Pseudomonas aeruginosa pathogenesis and therapeutics in military-relevant animal infection models

Modern combat-related injuries are often associated with acute polytrauma. As a consequence of severe combat-related injuries, a dysregulated immune response results in serious infectious complications. The gram-negative bacterium Pseudomonas aeruginosa is an opportunistic pathogen that often causes life-threatening bloodstream, lung, bone, urinary tract, and wound infections following combat-related injuries. The rise in the number of multidrug-resistant P. aeruginosa strains has elevated its importance to civilian clinicians and military medicine. Development of novel therapeutics and treatment options for P. aeruginosa infections is urgently needed. During the process of drug discovery and therapeutic testing, in vivo testing in animal models is a critical step in the bench-to-bedside approach, and required for Food and Drug Administration approval. Here, we review current and past literature with a focus on combat injury-relevant animal models often used to understand infection development, the interplay between P. aeruginosa and the host, and evaluation of novel treatments. Specifically, this review focuses on the following animal infection models: wound, burn, bone, lung, urinary tract, foreign body, and sepsis.

Terror-Related Trauma

In our current era, terrorist attacks have become a part of our daily life experience almost worldwide. New terrorist groups are emerging and the number of terrorist attacks is constantly rising.

Challenges in definitive fracture management of blast injuries

The United States military remains engaged in the longest armed conflict in this nation's history. The majority of casualties in the global war on terror come from blast-related injuries. Multiple centers have published their experience and outcomes with these complex patients. Findings from the study of injured military personnel have implications for mass casualty events resulting from industrial accidents or terrorism in the civilian sector. This article will review the pathophysiology of blast-related injury. The authors will summarize treatment considerations, priorities, and techniques that have proven successful. Finally, the authors will discuss the incidence and management of common complications after blast-related injuries.
