A systematic review of otologic injuries sustained in civilian terrorist explosions

PURPOSE

Determine the prevalence of otological symptoms and tympanic membrane perforation, healing rates of tympanic membrane perforation with surgical and conservative management, and hearing function in civilian victims of terrorist explosions.

METHODS

A systematic review was conducted with searches on Medline, Embase, EMCare and CINAHL for publications between the 1st January 1945 and 26th May 2023. Studies with quantitative data addressing our aims were included. This review is registered with PROSPERO: CRD42020166768. Among 2611 studies screened, 18 studies comprising prospective and retrospective cohort studies were included.

RESULTS

The percentage of eardrums perforated in patients admitted to hospital, under ENT follow up and attending the emergency department is 69.0% (CI 55.5-80.5%), 38.7% (CI 19.0-63.0%, I2 0.715%) and 21.0% (CI 11.9-34.3%, I2 0.718%) respectively. Perforated eardrums heal spontaneously in 62.9% (CI 50.4-73.8%, I2 0.687%) of cases and in 88.8% (CI 75.9-96.3%, I2 0.500%) of cases after surgery. Common symptoms present within one month of bombings are tinnitus 84.7% (CI 70.0-92.9%, I2 0.506%), hearing loss 83.0% (CI 64.5-92.9%, I2 0.505%) and ear fullness 59.7% (CI 13.4-93.4%, I2 0.719). Symptomatic status between one and six months commonly include no symptoms 57.5% (CI 46.0-68.3%), hearing loss 35.4% (CI 21.8-51.8%, I2 0.673%) and tinnitus 15.6% (CI 4.9-40.0%, I2 0.500%). Within one month of bombings, the most common hearing abnormality is sensorineural hearing loss affecting 26.9% (CI 16.9-40.1%, I2 0.689%) of ears 43.5% (CI 33.4-54.2%, I2 0.500) of people.

CONCLUSION

Tympanic membrane perforation, subjective hearing loss, tinnitus, ear fullness and sensorineural hearing loss are common sequelae of civilian terrorist explosions.

A global perspective on gun violence injuries

INTRODUCTION AND DEFINITIONS

Civilian gunshot violence is a growing public health issue on a global scale. Treatment of patients with gunshot injuries is based on algorithms derived from military studies, but the distinct differences in weaponry, energy of injury, timing and type of care, and environment translate to a gap in knowledge. With a focus on non-accidental gunshot trauma and excluding suicide etiologies, we propose to build a collaborative research group to address important questions focused on best practices for gunshot injury patients.

PRE-HOSPITAL CARE

There are important differences in the care of gunshot victims across the globe; some countries provide advanced interventions in the field and others deliver basic support until transport to a higher level of care in hospital. Some simple interventions include the use of extremity tourniquets and intravenous fluid support; others to consider are tranexamic acid, whole blood, and hemostatic agents.

ACUTE TREATMENT

Control of exsanguinating hemorrhage is a key priority for gunshot injuries. Military doctrine has evolved to prioritize exsanguination over airway or breathing as the critical first step. The X-ABC protocol focuses on exsanguinating hemorrhage, then standard evaluation of Airway, Breathing and Circulation (ABCs) to enhance survival in trauma patients. The timing of bony stabilization, in terms of damage-control vs definitive care, needs further study in this population, as does use of antibiotics for bony extremity injuries. Finally, recognition of the mental health effects of gun trauma, including post-traumatic stress disorder (PTSD), anxiety disorders, substance abuse and depression is important in advocating for prevention such as implementation of social support and specific interventions.

DEFINITIVE CARE

The need for abdominal closure after exploratory laparotomy, definitive fracture treatment, and other treatment all contribute to length of stay for gunshot injured patients. Optimizing stabilization allows earlier mobilization and decreases nosocomial complications. Nerve injuries are often a source of long-term disability and their evaluation and treatment require further investigation.

RESOURCES AND ETHICS

There are growing numbers of mass-casualty gunshot events, which require consideration of how to organize and use resources for treatment, including staff, operating room access, blood products, and order of treatment. Drills and planning for incident command hierarchy and communication are key to optimizing resource utilization. The ethics of choosing treatment priorities and resources are important considerations as well.

Military veterans and civilians' mental health diagnoses: an analysis of secondary mental health services

PURPOSE

Healthcare provision in the United Kingdom (UK) falls primarily to the National Health Service (NHS) which is free at the point of access. In the UK, there is currently no national marker to identify military veterans in electronic health records, nor a requirement to record it. This study aimed to compare the sociodemographic characteristics and recorded mental health diagnoses of a sample of veterans and civilians accessing secondary mental health services.

METHODS

The Military Service Identification Tool, a machine learning computer tool, was employed to identify veterans and civilians from electronic health records. This study compared the sociodemographic characteristics and recorded mental health diagnoses of veterans and civilians accessing secondary mental health care from South London and Maudsley NHS Foundation Trust, UK. Data from 2,576 patients were analysed; 1288 civilians and 1288 veterans matched on age and gender.

RESULTS

Depressive disorder was the most prevalent across both groups in the sample (26.2% veterans, 15.5% civilians). The present sample of veterans accessing support for mental health conditions were significantly more likely to have diagnoses of anxiety, depressive, psychosis, personality, and stress disorders (AORs ranging 1.41-2.84) but less likely to have a drug disorder (AOR = 0.51) than age- and gender-matched civilians.

CONCLUSION

Veterans accessing secondary mental health services in South London had higher risks for many mental health problems than civilians accessing the same services. Findings suggest that military career history is a key consideration for probable prognosis and treatment, but this needs corroborating in other geographical areas including national population-based studies in the UK.

Analysis of 983 civilian blast and ballistic casualties and the generation of a template of injury burden: An observational study

BACKGROUND

Terrorism and armed conflict cause blast and ballistic casualties that are unusual in civilian practice. The immediate surgical response to mass casualty events, with civilians injured by these mechanisms, has not been systematically characterised. Standardising an approach to reacting to these events is challenging but is essential to optimise preparation for them. We aimed to quantify and assesses the surgical response to blast and ballistic injuries managed in a world-class trauma unit paradigm.

METHODS

This was an observational study conducted at the UK-led military Medical Treatment Facility, Camp Bastion, Afghanistan from original theatre log-book entries between Nov 5, 2009, and Sept 21, 2014; a total of 10,891 consecutive surgical cases prospectively gathered by surgical teams were catalogued. Patients with combatant status/wearing body-armour to various degrees including interpreters were excluded from the study. Civilian casualties that underwent primary trauma surgery for blast and ballistic injuries were included (n=983). Surgical activity was analysed as a rate per 100 casualties, and patients were grouped according to adult vs. paediatric and ballistic vs. blast injury mechanisms to aid comparison.

FINDINGS

The three most common surgical procedures for civilian blast injuries were debridement, amputation, and laparotomy. For civilian ballistic injuries, these were debridement, laparotomy and vascular procedures. Blast injuries generated more amputations in both adults and children compared to ballistic injuries. Blast injuries generated more removal of fragmentation material compared to ballistics injuries amongst adult casualties. Ballistic injuries lead to more chest drain insertions in adults. As a rate per 100 casualties, adults injured by blast underwent significantly more debridement (63·5); temporary skeletal stabilisation (13·2) and vascular procedures (12·8) compared to children (43·4, z=4·026, p=0·00007; 5·7, z=2·230, p=0·022; 4·9, z=2·468, p=0·014). Adults injured by ballistics underwent significantly more debridement (63·4); chest drain (12·3) and temporary skeletal fixation procedures (11·4) compared to children (50·0, z=2·058, p=0.040, p<0·05; 2·9, z=2·283, p=0.0230; 2·9, z=2·131, p=0.034 respectively). By comparison, children injured by ballistics underwent significantly more removal of fragmentation and ballistic materials (20·6) when compared to adults (7·7, z=-3·234; p=0.001).

INTERPRETATION

This is the first evidence-based, template of the immediate response required to manage civilians injured by blast and ballistic mechanisms. The template presented can be applied to similar conflict zones and to prepare for terror attacks on urban populations.

Resuscitative endovascular balloon occlusion of the aorta in civilian pre-hospital care: a systematic review of the literature

Background

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a damage control tool with a potential role in the hemodynamic resuscitation of severely ill patients in the civilian pre-hospital setting. REBOA ensures blood flow to vital organs by early proximal control of the source of bleeding. However, there is no consensus on the use of REBOA in the pre-hospital setting. This article aims to perform a systematic review of the literature about the feasibility, survival, indications, complications, and potential candidates for civilian pre-hospital REBOA.

Methods

A literature search was conducted using Medline, EMBASE, LILACS and Web of Science databases. Primary outcome variables included overall survival and feasibility. Secondary outcome variables included complications and potential candidates for endovascular occlusion.

Results

The search identified 8 articles. Five studies described the use of REBOA in pre-hospital settings, reporting a total of 47 patients in whom the procedure was attempted. Pre-hospital REBOA was feasible in 68–100% of trauma patients and 100% of non-traumatic patients with cardiac arrest. Survival rates and complications varied widely. Pre-hospital REBOA requires a coordinated and integrated emergency health care system with a well-trained and equipped team. The remaining three studies performed a retrospective analysis identifying 784 potential REBOA candidates.

Conclusions

Pre-hospital REBOA could be a feasible intervention for a significant portion of severely ill patients in the civilian setting. However, the evidence is limited. The impact of pre-hospital REBOA should be assessed in future studies.

Identifying individuals with undiagnosed post-traumatic stress disorder in a large United States civilian population - a machine learning approach

BACKGROUND

The proportion of patients with post-traumatic stress disorder (PTSD) that remain undiagnosed may be substantial. Without an accurate diagnosis, these patients may lack PTSD-targeted treatments and experience adverse health outcomes. This study used a machine learning approach to identify and describe civilian patients likely to have undiagnosed PTSD in the US commercial population.

METHODS

The IBM® MarketScan® Commercial Subset (10/01/2015-12/31/2018) was used. A random forest machine learning model was developed and trained to differentiate between patients with and without PTSD using non-trauma-based features. The model was applied to patients for whom PTSD status could not be confirmed to identify individuals likely and unlikely to have undiagnosed PTSD. Patient characteristics, symptoms and complications potentially related to PTSD, treatments received, healthcare costs, and healthcare resource utilization were described separately for patients with PTSD (Actual Positive PTSD cohort), patients likely to have PTSD (Likely PTSD cohort), and patients without PTSD (Without PTSD cohort).

RESULTS

A total of 44,342 patients were classified in the Actual Positive PTSD cohort, 5683 in the Likely PTSD cohort, and 2,074,471 in the Without PTSD cohort. While several symptoms/comorbidities were similar between the Actual Positive and Likely PTSD cohorts, others, including depression and anxiety disorders, suicidal thoughts/actions, and substance use, were more common in the Likely PTSD cohort, suggesting that certain symptoms may be exacerbated among those without a formal diagnosis. Mean per-patient-per-6-month healthcare costs were similar between the Actual Positive and Likely PTSD cohorts ($11,156 and $11,723) and were higher than those of the Without PTSD cohort ($3616); however, cost drivers differed between cohorts, with the Likely PTSD cohort experiencing more inpatient admissions and less outpatient visits than the Actual Positive PTSD cohort.

CONCLUSIONS

These findings suggest that the lack of a PTSD diagnosis and targeted management of PTSD may result in a greater burden among undiagnosed patients and highlights the need for increased awareness of PTSD in clinical practice and among the civilian population.

CIVILIAN GUNSHOT OROFACIAL INJURY IN A NIGERIAN TERTIARY HOSPITAL: A 10-YEAR RETROSPECTIVE REVIEW

Background

Gunshot related injuries to the face are relatively rare in peacetime. This study reported the pattern of presentation and management of orofacial civilian gunshot injuries at a Nigerian tertiary hospital.

Methodology

Medical records of 25 patients who sustained gunshot injuries to the face and were managed at the Obafemi Awolowo University Teaching Hospitals Complex, Ile Ife between 2010 and 2019 were reviewed. Patients' demographics, wounding mechanisms, clinical presentations and treatment administered were retrieved from the patients' case record. Patient records with incomplete information were excluded. Data generated were inputed into IBM-SPSS version 26 and analysed.

Results

A total of 2,847 patients were admitted through our department over the study period and 28 of them sustained orofacial gunshot injuries, giving a prevalence of 0.98%. Twenty-five out of the 28 retrieved case files met the inclusion criteria. There were 22 males and 3 females; with a male to female ratio of 7.3:1. The mean age was 37.60 ± 11.86 years with highest prevalence at fourth decade of life. About two-thirds of these injuries were intentionally inflicted by others with the use of Dane guns on highways. Majority (64%) of these injuries involved the middle third of the face. Definitive treatments ranged from simple to complex reconstructive procedures to restore pre-injury form and functions.

Conclusion

Gunshot injury involving the maxillofacial region is uncommon during peace time. The male gender was predominantly affected and the middle third facial skeleton was the most involved anatomic site. Most of the injuries were intentionally inflicted by others using Dane gun.

A systematic review of penetrating perineal trauma in a civilian setting

PURPOSE

Penetrating injuries to the perineum and associated pelvic organs have largely been reported in the military. Given the rarity of presentation and unique clinical characteristics of these injuries, we set out to address the gap in the literature in civilian settings.

METHODS

A systematic review of studies addressing penetrating perineal trauma from January 2000 to April 2021 was performed. Outcomes of interest were the epidemiology, associated injuries, management, follow-up, and patient outcomes.

RESULTS

26 studies were included in this review, reporting on a total of 2316 patients. Most injuries occurred in males (88.1%), with gunshot wounds (88.2%) representing the most common aetiology, followed by knife wounds (5.0%), impalement (3.1%), coital injuries/sexual assault (1.5%), and others (2.4%). Regarding associated injuries, anorectal (n = 1419, 69.4%), bladder (n = 351, 32.4%), penile (n = 282, 20.8%), scrotal (n = 375, 27.7%), and testicular (n = 229, 16.9%) occurred frequently. Bony injuries involved the pelvis (n = 88, 8.1%) and femoral fractures (n = 5, 0.5%), while soft-tissue injuries involved the inguinal region (n = 19, 1.6%) and buttocks (n = 14, 1.3%). Vascular injuries occurred in 79 (7.8%) patients. Regarding patient outcomes, 65 (4.8%) deaths were reported, and significant morbidity was detected with a mean injury severity score of 18.4 detected in the cohort. In terms of complications of injury, wound/infective complications (n = 135, 61.3%) and fistula formation/leakage (n = 16, 0.7%) featured prominently.

CONCLUSION

Penetrating perineal trauma in the civilian population poses a considerable challenge to clinicians, compounded by the potential for multisystem injury requiring involvement of different medical and surgical specialties.

Civilian-military malaria outbreak response in Thailand: an example of multi-stakeholder engagement for malaria elimination

BACKGROUND

In April 2017, the Thai Ministry of Public Health (MoPH) was alerted to a potential malaria outbreak among civilians and military personnel in Sisaket Province, a highly forested area bordering Cambodia. The objective of this study was to present findings from the joint civilian-military outbreak response.

METHODS

A mixed-methods approach was used to assess risk factors among cases reported during the 2017 Sisaket malaria outbreak. Routine malaria surveillance data from January 2013 to March 2018 obtained from public and military medical reporting systems and key informant interviews (KIIs) (n = 72) were used to develop hypotheses about potential factors contributing to the outbreak. Joint civilian-military response activities included entomological surveys, mass screen and treat (MSAT) and vector control campaigns, and scale-up of the "1-3-7" reactive case detection approach among civilians alongside a pilot "1-3-7" study conducted by the Royal Thai Army (RTA).

RESULTS

Between May-July 2017, the monthly number of MoPH-reported cases surpassed the epidemic threshold. Outbreak cases detected through the MoPH mainly consisted of Thai males (87%), working as rubber tappers (62%) or military/border police (15%), and Plasmodium vivax infections (73%). Compared to cases from the previous year (May-July 2016), outbreak cases were more likely to be rubber tappers (OR = 14.89 [95% CI: 5.79-38.29]; p < 0.001) and infected with P. vivax (OR=2.32 [1.27-4.22]; p = 0.006). Themes from KIIs were congruent with findings from routine surveillance data. Though limited risk factor information was available from military cases, findings from RTA's "1-3-7" study indicated transmission was likely occurring outside military bases. Data from entomological surveys and MSAT campaigns support this hypothesis, as vectors were mostly exophagic and parasite prevalence from MSAT campaigns was very low (range: 0-0.7% by PCR/microscopy).

CONCLUSIONS

In 2017, an outbreak of mainly P. vivax occurred in Sisaket Province, affecting mainly military and rubber tappers. Vector control use was limited to the home/military barracks, indicating that additional interventions were needed during high-risk forest travel periods. Importantly, this outbreak catalyzed joint civilian-military collaborations and integration of the RTA into the national malaria elimination strategy (NMES). The Sisaket outbreak response serves as an example of how civilian and military public health systems can collaborate to advance national malaria elimination goals in Southeast Asia and beyond.

The relationship between substance use, prior trauma history, and risk of developing post-traumatic stress disorder in the immediate aftermath of civilian trauma

Many reports have documented the relationship between post-traumatic stress disorder (PTSD) and substance use. Substance use is commonly comorbid with PTSD and is a risk factor for trauma exposure. The aim of this study was to prospectively examine how recent substance use, abuse, or dependence influenced the development of PTSD in the context of a prior trauma history, including child abuse, and the severity of initial trauma reactions. Participants (N = 81) were recruited and assessed at the emergency department of a large urban hospital in Miami and serum levels of common drugs of abuse were measured. Although substance use appeared to be a risk factor for trauma exposure, neither self-reported nor blood toxicology influenced the development of PTSD. Positive toxicology screens were more likely to be associated with a diagnosis of substance abuse or dependence, χ² (1) = 4.11, p = .04. Participants with a history of physical abuse were more likely to have a positive toxicology screen, χ² (1) = 4.03, p = .05. The majority of our trauma-exposed subjects (66%) were found to be positive for one or more illicit substances at presentation at the ED. The current findings provide support for the "high risk" hypothesis in which substance use is associated with increased trauma exposure.

Defining blast loading 'zones of relevance' for primary blast injury research: A consensus of injury criteria for idealised explosive scenarios

Blast injuries remain a serious threat to defence and civilian populations around the world. 'Primary' blast injuries (PBIs) are caused by direct blast wave interaction with the human body, particularly affecting air-containing organs. Work to define blast loading conditions for injury research has received relatively little attention, though with a continued experimental focus on PBIs and idealised explosion assumptions, meaningful test outcomes and subsequent clinical applications, rely on appropriate simulated conditions. This paper critically evaluates and combines existing PBI criteria (grouped into those affecting the auditory system, pulmonary injuries and brain trauma) as a function of idealised blast wave parameters. For clinical blast injury researchers, analysis of the multi-injury criteria indicates zones of appropriate loading conditions for human-scale test items and demonstrates the importance of simulating blast conditions that are both realistic and relevant to the injury type. For certain explosive scenarios, spatial interpretation of the 'zones of relevance' could support emergency response and hazard preparedness by informing triage, patient management and resource allocation, thus leading to improved health outcomes. This work will prove useful to clinical blast injury researchers, blast protection engineers and clinical practitioners involved in the triage, diagnosis, and treatment of PBIs.

Civilian gunshot injuries in orthopaedics: a narrative review of ballistics, current concepts, and the South African experience

The incidence of civilian gunshot injuries is on the rise worldwide.Unfortunately, there is a lack of high-level evidence guiding management. The treatment of orthopaedic injuries from gunshots is complex and requires consideration of multiple aspects, including energy transfer to the tissue, severity of the wound, possible contamination, presence of fractures and associated injuries. With this narrative review we aim to discuss some of the relevant ballistics, current concepts, and controversies in the general management of civilian gunshot-related orthopaedic injuries based on the available evidence and personal experience. Important points which will be highlighted are the initial management in the emergency room, the assessment and management of soft tissue injuries, associated injuries, use of antibiotics, indication and techniques for fracture fixation, and gunshot injuries to joints.

Ordinary injury, big surprise - Traumatic false aneurysm and arteriovenous fistula of the posterior tibial artery after civilian trauma: A case report

Introduction

False traumatic aneurysm (FTA) or pseudoaneurysm and traumatic arteriovenous fistulas (TAVF) are rare pathologies in civilian trauma and mainly result from stabs or gunshot wounds. The posterior tibial artery as site of trauma is very rare.

Presentation of case

We report on a 39-year old female patient who was suffering from combined FTA and TAVF of the posterior tibial artery after falling into a wine glass. CT-imaging as well as duplex ultrasound and selective arteriography were performed, and two stent-grafts were inserted.

Discussion

Based on the presented case, incidence of the described pathology, treatment options and outcomes are discussed.

Conclusion

Adequate imaging in penetrating wounds to the extremities is crucial in order to provide diagnosis and treatment of concomitant lesions.

Lived experience of medical veterans transitioning from military service to civilian nursing education

BACKGROUND

Many veterans take advantage of the educational benefits afforded them after service. As veterans, students in higher education are a special population with subsequent needs.

PURPOSE

The purpose of this study was to explore the lived experience of medic student veterans attending a full-time Bachelor of Science in Nursing (BSN) program.

METHOD

This study used the hermeneutic phenomenology research approach to explore the lived experiences of student veterans with military medic experience enrolled in a Bachelor of Science in Nursing (BSN) program.

RESULTS

While our study revealed diverse student experiences among these veterans, common themes included staying true to military training, normal life, and fitting in as a university student.

CONCLUSIONS

Findings in this study substantiate medic student veterans attending nursing school represent a unique cohort which can benefit from customized services from the university.

Triggers and Clinical Presentations of Functional Neurological Disorders: Lessons from World War 1

INTRODUCTION

The psychological contribution to functional neurological and somatic symptom disorders is a major topic in current medical debate.

OBJECTIVE

For an understanding of the processes leading to functional somatic symptoms, it is paramount to explore their relationship with stress and life events and to elucidate the contribution of cultural factors.

METHODS

A total of 937 case records of civilian and military patients with functional somatic disorders treated in London during World War 1 were analysed. Group differences in symptom profiles and contemporaneous diagnoses were tested with χ2 tests.

RESULTS

Paralyses and speech disturbances were significantly more common in soldiers (43.3 and 17.2% of cases) than in civilian male (28.1 and 6.5%) and female patients (32.4 and 7.5%), whereas female patients had the highest rates of pain (48.6%) and somatic symptoms (67%). Triggers were identified in around two-thirds of cases and included accidents, physical illness, and work stress, in addition to the combat experience of the soldier patients. The nature of the trigger influenced symptom expression, with acute (combat and noncombat) events being particularly prone to trigger loss of motor function. Symptom profiles showed a great deal of multi-morbidity and overlap, although some symptom clusters were more (motor and speech disturbance) or less common (pain and loss of energy) in soldiers than civilians. Triggering life events in civilians were similar to those reported by patients with somatic symptom disorders today, with an important role of physical factors. Patterns of multi-morbidity and symptom clusters also resembled those of modern cohorts.

CONCLUSIONS

Analysis of historical records, illness trajectories, and treatments can enhance the understanding of the presentation, mechanisms, and course of functional neurological and related disorders and their consistency over time.

Facilitators and constrainers of civilian-military collaboration: the Swedish perspectives

Purpose

An increasing number of international and domestic armed conflicts, including terror attacks on civilians, along with constrained healthcare finance and resource limitation, has made a civilian–military collaboration (CMC) crucial. The purpose of this study was to identify facilitators and constrainers in CMC in a national perspective with a specific focus on medical aspects.

Method

A literature review of recently published papers about civilian–military collaboration, along with a short survey, was conducted. For the review, major search engines were used.

Results

The results indicated many facilitators, but few important constrainers with a high impact on the outcome. The conducted survey indicated discrepancies between the needs and resources.

Conclusion

The current global and domestic security threats and challenges, make CMC critical and inevitable. However, there is a need for careful analysis of its consequences, impact, possibilities, and limitations to differentiate between our expectations and the current reality.

Cancer incidence and all-cause mortality among civilian men and women employed by the Royal Norwegian Navy between 1950 and 2005

OBJECTIVE

We aimed to investigate cancer incidence and all-cause mortality in a cohort of 8358 civilians (5134 men and 3224 women) employed by the Royal Norwegian Navy at any time between 1950 and 2005.

METHODS

The cohort was followed for cancer incidence and all-cause mortality from 1960 through 2015. Standardised incidence ratios (SIR) and mortality ratios (SMR) were calculated from national rates. Separate SIRs were calculated for a subgroup of male workshop workers and another of female cleaners.

RESULTS

Overall cancer incidence among men was similar to the reference rate; male breast cancer was more frequent (SIR = 3.23). Male workshop workers showed a SIR of 1.77 for stomach cancer, while their incidence of lympho-haematopoietic cancers was half that of the reference rates. Women had increased risks of overall cancer (SIR = 1.11), lung cancer (SIR = 1.35), and ovarian cancer (SIR = 1.39). Female cleaners showed a SIR of 2.33 for bladder cancer and a lowered incidence of brain cancer (SIR = 0.18). In the overall cohort, all-cause mortality was lower than expected for men (SMR = 0.92) and closer to the reference rate for women (SMR = 0.95).

CONCLUSION

In men, we observed a lowered all-cause mortality and an excess of stomach cancer in workshop workers. In women, increased risks of overall cancer, lung cancer and ovarian cancer was seen. An increased risk of bladder cancer and a lowered incidence of brain cancer was observed among female cleaners.

Spinal Gunshot Wounds: Pattern and Associated Lesions in Civilians

STUDY DESIGN

Retrospective, descriptive case series study.

PURPOSE

To investigate the frequency, bone pattern, and associated lesions to the spine of gunshot wounds.

OVERVIEW OF LITERATURE

Gunshot wounds are penetrating in nature and are caused by a bullet or projectile. These are becoming more common and are associated with significant sequelae, requiring long and costly multidisciplinary treatment. Associated spinal cord injuries (SCIs) in the civilian population represent 13%-17% of all spinal traumas. Spinal gunshot wounds are commonly thought to be stable; however, there is potential acute and chronic spinal instability if the bullet passes transversely, fracturing either both pedicles or both facet joints.

METHODS

We obtained data from the clinical files of patients with spinal gunshot wounds treated by spine surgeons. We performed a statistical analysis to obtain the pattern and frequency of the injuries.

RESULTS

We included 54 patients (48 men [89%] and six women [11%]). Eight patterns of spinal gunshot wounds were identified; 61% (33 patients) had complete SCI. The thoracic spine was most frequently affected, with 88% of patients having SCI; 75%, hemopneumothorax; 28%, pulmonary lesions; and 16%, hepatic lesions. The presence of pedicle fractures had an odds ratio of 3.64 for SCI.

CONCLUSIONS

The two main bone patterns are the vertebral body and posterior arch with pedicle fractures as modifiers, given that they are at a high risk for SCI. The spinal pattern and associated lesions were related to the bullet's path, with the vertebral body having the highest frequency of associated lesions. Vertebral body burst fracture was the main indication for instrumentation.

Epidemiological findings of major chemical attacks in the Syrian war are consistent with civilian targeting: a short report

Evidence of use of toxic gas chemical weapons in the Syrian war has been reported by governmental and non-governmental international organizations since the war started in March 2011. To date, the profiles of victims of the largest chemical attacks in Syria remain unknown. In this study, we used descriptive epidemiological analysis to describe demographic characteristics of victims of the largest chemical weapons attacks in the Syrian war. We analysed conflict-related, direct deaths from chemical weapons recorded in non-government-controlled areas by the Violation Documentation Center, occurring from March 18, 2011 to April 10, 2017, with complete information on the victim's date and place of death, cause and demographic group. 'Major' chemical weapons events were defined as events causing ten or more direct deaths. As of April 10, 2017, a total of 1206 direct deaths meeting inclusion criteria were recorded in the dataset from all chemical weapons attacks regardless of size. Five major chemical weapons attacks caused 1084 of these documented deaths. Civilians comprised the majority (n = 1058, 97.6%) of direct deaths from major chemical weapons attacks in Syria and combatants comprised a minority of 2.4% (n = 26). In the first three major chemical weapons attacks, which occurred in 2013, children comprised 13%-14% of direct deaths, ranging in numbers from 2 deaths among 14 to 117 deaths among 923. Children comprised higher proportions of direct deaths in later major chemical weapons attacks, forming 21% (n = 7) of 33 deaths in the 2016 major attack and 34.8% (n = 32) of 92 deaths in the 2017 major attack. Our finding of an extreme disparity in direct deaths from major chemical weapons attacks in Syria, with 97.6% of victims being civilians and only 2.4% being combatants provides evidence that major chemical weapons attacks were indiscriminate or targeted civilians directly; both violations of International Humanitarian Law (IHL). Identifying and quantifying chemical weapons violations requires inter-disciplinary collaboration to inform international policy, humanitarian intervention and legal action.

Trauma exposure and the mediating role of posttraumatic stress on somatic symptoms in civilian war victims

BACKGROUND

It has been well documented that the exposure to war has a negative effect on the psychological health of civilian. However, little is known on the impact of war exposure on the physical health of the civilian population. In addition, the link between trauma exposure and somatic symptoms remain poorly understood. This cross-sectional study examined levels of somatic symptoms in the aftermath of war, and the mediating role of posttraumatic stress symptoms in the relationship between trauma exposure and somatic symptoms.

METHODS

Civilian war survivors (N = 142) from Kosovo were assessed for potentially traumatic events, posttraumatic stress symptoms, and somatic symptoms. Data were analyzed using mediation analyses. Posttraumatic stress disorder (PTSD) symptoms were categorized based on King's four factor model (Psychol Assessment. 10: 90-96, 1998).

RESULTS

Participants reported on average more than 5 types of traumatic exposure. The cut-off indicative for PTSD was exceeded by 26.1% of participants. Symptom levels of PTSD were associated with somatic symptoms. The relationship between trauma exposure and somatic symptoms was partly mediated by the active avoidance and hyperarousal symptom clusters of PTSD.

CONCLUSION

Active avoidance and hyperarousal symptoms seem to play a key role in traumatized people suffering from somatic symptoms.

Quality of life of burn survivors treated in the military burn center

BACKGROUND

Limited research explains the quality of life (QOL) among burn survivors during post-hospitalization rehabilitation.

PURPOSE

To determine the QOL of military and civilian burn survivors treated in the military burn center.

METHODS

In this longitudinal study, QOL was examined in 131 burn survivors (88 civilians; 43 military). Participants completed the Abbreviated Burn Specific Health Scale (BSHS-A) and the Satisfaction with Life Scale (SWLS) over 5 time points post-discharge.

DISCUSSION

Civilian and military participants reported improved QOL over time on most BSHS-A subscales. Military participants had higher global BSHS-A scores at discharge, but at 6 months plateaued while civilians improved and had higher global BSHS-A scores at 18 months. Scores on the SWLS were consistently higher for military participants than for civilians.

CONCLUSION

Military versus civilian patients may have different expectations about their ability to rehabilitate. The post-hospitalization period needs to be better understood to develop appropriate QOL interventions.

Educating nurses to care for military veterans in civilian hospitals: An integrated literature review

BACKGROUND

In the UK, military veterans will receive care by civilian nurses in civilian hospitals. We propose that the nurses providing this care require an understanding of the unique experiences and specific health needs of veterans to deliver evidence-based care.

AIM

To conduct an integrative review of published literature to explore how nursing programmes prepare nurses to care for the military veteran population in civilian hospitals.

REVIEW METHODS

A systematic search was undertaken of a range of electronic databases, Google Scholar and hand searching of Military and Veteran health journals. Papers that focused on education of civilian nurses about veteran health and included primary research or description of practice-based innovations were included in the review.

RESULTS

The search generated sixteen papers that were focused on nurse education in higher education institutions. Several papers focused on simulation as a teaching method for veteran-specific health issues or curriculum developments with educational innovations such as online courses. Six papers focusing in continuing professional education of nurses in the clinical setting were included as supplementary information. All papers reviewed were US focused and dated between January 2011 and September 2015. Our search concluded that there is a gap in knowledge in this subject area within a UK context, therefore our review includes UK background information to support the US findings.

CONCLUSION

Civilian nurses need educational preparation to understand the specific needs of veterans. Educational institutions in the US have responded to nationwide initiatives to undertake that preparation. More empirical studies need to be undertaken to develop, test and evaluate educational innovations for preparing students and nurses delivering care to military veteran in civilian healthcare settings.

Pre-hospital management of mass casualty civilian shootings: a systematic literature review

BACKGROUND

Mass casualty civilian shootings present an uncommon but recurring challenge to emergency services around the world and produce unique management demands. On the background of a rising threat of transnational terrorism worldwide, emergency response strategies are of critical importance. This study aims to systematically identify, describe and appraise the quality of indexed and non-indexed literature on the pre-hospital management of modern civilian mass shootings to guide future practice.

METHODS

Systematic literature searches of PubMed, Cochrane Database of Systematic Reviews and Scopus were conducted in conjunction with simple searches of non-indexed databases; Web of Science, OpenDOAR and Evidence Search. The searches were last carried out on 20 April 2016 and only identified those papers published after the 1 January 1980. Included documents had to contain descriptions, discussions or experiences of the pre-hospital management of civilian mass shootings.

RESULTS

From the 494 identified manuscripts, 73 were selected on abstract and title and after full text reading 47 were selected for inclusion in analysis. The search yielded reports of 17 mass shooting events, the majority from the USA with additions from France, Norway, the UK and Kenya. Between 1994 and 2015 the shooting of 1649 people with 578 deaths at 17 separate events are described. Quality appraisal demonstrated considerable heterogeneity in reporting and revealed limited data on mass shootings globally.

CONCLUSION

Key themes were identified to improve future practice: tactical emergency medical support may harmonise inner cordon interventions, a need for inter-service education on effective haemorrhage control, the value of senior triage operators and the need for regular mass casualty incident simulation.

Casualties of war: the infection control assessment of civilians transferred from conflict zones to specialist units overseas for treatment

The casualties of global conflict attract media attention and sympathy in public, governmental, and non-governmental circles. Hospitals in developed countries offering specialist reconstructive or tertiary services are not infrequently asked to accept civilian patients from overseas conflict for complex surgical procedures or rehabilitation. Concern about the infection prevention and control risks posed by these patients, and the lack of a good evidence base on which to base measured precautions, means that the precautionary principle of accepting zero risk is usually followed. The aim of this article is to highlight infection control considerations that may be required when treating casualties from overseas conflict, based partly on our own experience. Currently there is a lack of published evidence and national consensus on how to manage these patients. The precautionary principle requires that there is an ongoing search for evidence and knowledge that can be used to move towards more traditional risk management. We propose that only by gathering the experiences of the many individual hospitals that have each cared for small numbers of such patients can such evidence and knowledge be assimilated.

Management of civilian ballistic fractures

INTRODUCTION

The management of ballistic fractures, which are open fractures, has often been studied in wartime and has benefited from the principles of military surgery with debridement and lavage, and the use of external fixation for bone stabilization.

HYPOTHESIS

In civilian practice, bone stabilization of these fractures is different and is not performed by external fixation.

PATIENTS AND METHODS

Fifteen civilian ballistic fractures, Gustilo II or IIIa, two associated with nerve damage and none with vascular damage, were reviewed. After debridement and lavage, ten internal fixations and five conservative treatments were used.

RESULTS

No superficial or deep surgical site infection was noted. Fourteen of the 15 fractures (93%) healed without reoperation. Eleven of the 15 patients (73%) regained normal function.

DISCUSSION

Ballistic fractures have a bad reputation due to their many complications, including infections. In civilian practice, the use of internal fixation is not responsible for excessive morbidity, provided debridement and lavage are performed. Civilian ballistic fractures, when they are caused by low-velocity firearms, differ from military ballistic fractures. Although the principle of surgical debridement and lavage remains the same, bone stabilization is different and is similar to conventional open fractures.
