Abstract
AbstractIntroduction: This study intended to describe the types of organizations and communities in which Nationally Registered First Responders (NRFR) perform their duties. Also, it aimed to estimate the number of NRFR who received disaster preparedness training. It was hypothesized that NRFR participation in disaster preparedness training was related to the types of organizations and communities in which they performed their duties.Methods: The NRFR re-registering in 2006 were asked to report the organization type and community size in which they work. They also were asked to report the amount and content of preparedness training received during the last 24 months. Multivariable logistic regression modeling was utilized to describe the relationship between NRFR organizational characteristics and the receipt of disaster preparedness training.Results: The analysis included 872 (59%) individuals who completed the survey and reported working for one or more emergency medical services (EMS) organizations. The majority of NRFR performed work in rural areas (75%) and more NRFR reported working for fire departments (61%) than for any other organization type. In all categories of service type, participants who reported working in urban areas had higher odds of receiving disaster preparedness training than those working in rural areas. Additionally, regardless of community size, individuals working in fire departments were more likely to receive disaster preparedness training.Conclusions: This study indicated that the majority of NRFR perform EMS duties for fire departments and work in rural communities. In this sample of NRFR, more than one-quarter did not receive disaster preparedness training within a 24-month period. Finally, a statistical model was constructed that indicated a relationship between service type, community size, and the participation in disaster preparedness training.

Abstract
Tannerite(®) is a proprietary blend of an oxidizer, ammonium nitrate, and aluminum powder catalyst used to make homemade exploding targets. While it is currently approved for unrestricted sale in the United States, it can be used to form devices capable of inflicting major blast injury. We present here a case of close proximity exposure to detonation of the mixed Tannerite(®) blend. In our patient, the exposure lead to injuries typical of blast injury, such as tympanic membrane rupture, globe injury, and severe burns. We review here the sequelae of blast injuries that one must consider when treating a patient with close proximity exposure to Tannerite, with considerations unique to this product.

Abstract
Recent armed conflicts and the expanded reach of international terror groups has resulted in an increased incidence of blast-related injuries in both military and civilian populations. Mass-casualty incidents may require both on-scene and in-hospital triage to maximize survival rates and conserve limited resources. Initial evaluation should focus on the identification and control of potentially life-threatening conditions, especially life-threatening hemorrhage. Early operative priorities for musculoskeletal injuries focus on the principles of damage-control orthopaedics, with early and aggressive debridement of soft-tissue wounds, vascular shunting or grafting to restore limb perfusion, and long-bone fracture stabilization via external fixation. Special considerations such as patient transport, infection control and prevention, and amputation management are also discussed. All orthopedic surgeons, regardless of practice setting, should be familiar with the basic principles of evaluation, resuscitation, and initial management of explosive blast injuries.

Abstract
BACKGROUND Blast injuries in the United States and worldwide are not uncommon. Partially due to the increasing frequency of both domestic and international terrorist bombing attacks, it is prudent for all emergency physicians to be knowledgeable about blasts and the spectrum of associated injuries. OBJECTIVE Our aim was to describe blast physiology, types of blast injuries associated with each body system, and manifestations and management of each injury. DISCUSSION Blast injuries are generally categorized as primary to quaternary injuries. Primary injuries result from the effect of transmitted blast waves on gas-containing structures, secondary injuries result from the impact of airborne debris, tertiary injury results from transposition of the entire body due to blast wind or structural collapse, and quaternary injuries include almost everything else. Different body systems are affected and managed differently. Despite previous dogma, multiple studies now show that tympanic membrane perforation is a poor predictor of other blast injury. CONCLUSIONS Blast events can produce a myriad of injuries affecting any and every body system. All emergency physicians should be familiar with the presentation and management of these injuries. This knowledge may also be incorporated into triage and discharge protocols guiding management of mass casualty events.

Abstract
OBJECTIVES Ballistic injuries to peripheral nerves pose special challenges in terms of indications, timing and type of surgical intervention. The aim of the present work was to analyze our experience in the surgical treatment of peripheral nerve ballistic injuries with respect to the mechanism of injury (gunshot versus shrapnel), and identify common and dissimilar prognostic factors in both types of injury. METHODS This study was conducted on 42 patients totaling 58 nerves. Twenty-two patients (32 nerves) were injured by gunshot and 20 patients (26 nerves) by shrapnel. Median postoperative follow-up was 33 months (range 12 months to 14 years). RESULTS Overall postoperative outcome appears to be more favorable for gunshot-wound (GSW) patients than shrapnel-injured patients, especially in terms of neuropathic pain relief (75 % vs. 58 % respectively, p < 0.05). Presence of foreign particles in shrapnel injured patients has a negative impact on the surgical outcome in terms of rate of pain improvement (28 % compared to 67 % in patients with and without foreign particles, respectively). Nerve graft reconstruction, rather than neurolysis, seems to be the more beneficial treatment for shrapnel-induced neuropathic pain (100 % vs. 47 % in improvement rate, respectively). Early surgical intervention (median 2 months after injury) significantly relieved neuropathic pain in 83 % of shrapnel-injured patients compared to 58 % in patients operated later. CONCLUSIONS This study suggests that shrapnel injury is more destructive for nerve tissue than gunshot injury. Our impression is that early surgical intervention in shrapnel injuries and split nerve grafting (especially when small fragments are recognized in the nerve) significantly improve the patient's functional activity and quality of life.

Abstract
The immediate patterns of injury from explosions are well documented, from both military and civil experience. However, few studies have focused on less immediately apparent health consequences and latent effects of explosions in survivors, emergency responders and the surrounding community. This review aimed to analyze the risks to health following an explosion in a civil setting. A comprehensive review of the open literature was conducted, and data on 10 relevant military, civilian and industrial events were collected. Events were selected according to availability of published studies and involvement of large numbers of people injured. In addition, structured interviews with experts in the field were conducted, and existing national guidelines reviewed. The review revealed significant and potentially long-term health implications affecting various body systems and psychological well-being following exposure to an explosion. An awareness of the short- and long-term health effects of explosions is essential in screening for blast injuries, and identifying latent pathologies that could otherwise be overlooked in stressful situations with other visually distracting injuries and, often, mass casualties. Such knowledge would guide responsible medical staff in implementing early appropriate interventions to reduce the burden of long-term sequelae. Effective planning and response strategies would ensure accessibility of appropriate health care resources and evidence-based information in the aftermath of an explosion.

Abstract
Improvised explosive devices (IEDs) are one of the main causes for casualties among civilians and military personnel in the present war against terror. Mild traumatic brain injury from IEDs induces various degrees of cognitive, emotional and behavioral disturbances but knowledge of the exact brain pathophysiology following exposure to blast is poorly understood. The study was aimed at establishing a murine model for a mild BI-TBI that isolates low-level blast pressure effects to the brain without systemic injuries. An open-field explosives detonation was used to replicate, as closely as possible, low-level blast trauma in the battlefield or at a terror-attack site. No alterations in basic neurological assessment or brain gross pathology were found acutely in the blast-exposed mice. At 7 days post blast, cognitive and behavioral tests revealed significantly decreased performance at both 4 and 7 m distance from the blast (5.5 and 2.5 PSI, respectively). At 30 days post-blast, clear differences were found in animals at both distances in the object recognition test, and in the 7 m group in the Y maze test. Using MRI, T1 weighted images showed an increased BBB permeability 1 month post-blast. DTI analysis showed an increase in fractional anisotropy (FA) and a decrease in radial diffusivity. These changes correlated with sites of up-regulation of manganese superoxide dismutase 2 in neurons and CXC-motif chemokine receptor 3 around blood vessels in fiber tracts. These results may represent brain axonal and myelin abnormalities. Cellular and biochemical studies are underway in order to further correlate the blast-induced cognitive and behavioral changes and to identify possible underlying mechanisms that may help develop treatment- and neuroprotective modalities.

Abstract
OBJECTIVES During disasters, the public expects that emergency care will be available at a moment's notice. As such, an emergency medical services (EMS) workforce that is trained and prepared for disasters is imperative. The primary objectives of this study were to quantify the amount of individual-level training EMS professionals receive in terrorism and disaster-preparedness, as well as to assess EMS professionals' participation in multiagency disaster drills across the United States. Characteristics of those most likely to have received individual-level training or participated in multiagency disaster drills were explored. The secondary objectives were to assess EMS professional's perception of preparedness and to determine whether the amount of training individuals received was correlated with their perceptions of preparedness. METHODS A structured survey was administered to nationally certified EMT-Basics and paramedics as part of their 2008 recertification paperwork. Outcome variables included individual-level preparedness training, participation in multiagency disaster drills, and perception of preparedness. Descriptive statistics and logistic regression modeling were used to quantify the amount of training received. Spearman rank correlation coefficients were used to analyze whether training was correlated with an individual's perception of preparedness. RESULTS There were 46,127 EMS professionals who had the opportunity to complete the recertification questionnaire; 30,570 (66.3%) responded. A complete case analysis was performed on 21,438 respondents. Overall, 19,551 respondents (91.2%) reported receiving at least 1 hour of individual-level preparedness training, and 12,828 respondents (59.8%) reported participating in multiagency disaster drills, in the prior 24 months. Spearman rank correlation coefficients revealed that hours of individual-level preparedness training were significantly correlated with the perception of preparedness. CONCLUSIONS While areas where EMS should focus attention for improvement were identified, a majority of nationally certified EMT-Basics and paramedics reported participating in both individual and multiagency disaster-preparedness training. A large majority of respondents reported feeling adequately prepared to respond to man-made and natural disasters and the perception of preparedness correlated with hours of training.

Abstract
In armed conflicts and during terrorist attacks, explosive devices are a major cause of mortality. The lung is one of the organs most sensitive to blasts. Thus, today it is important that every GP at least knows the basics and practices regarding treatment of blast victims. We suggest, following a review of the explosions and an assessment of the current threats, detailing the lung injuries brought about by the explosions and the main treatments currently recommended.

Abstract
Health-care providers are increasingly faced with the possibility of needing to care for people injured in explosions, but can often, however, feel undertrained for the unique aspects of the patient's presentation and management. Although most blast-related injuries (eg, fragmentation injuries from improvised explosive devices and standard military explosives) can be managed in a similar manner to typical penetrating or blunt traumatic injuries, injuries caused by the blast pressure wave itself cannot. The blast pressure wave exerts forces mainly at air-tissue interfaces within the body, and the pulmonary, gastrointestinal, and auditory systems are at greatest risk. Arterial air emboli arising from severe pulmonary injury can cause ischaemic complications-especially in the brain, heart, and intestinal tract. Attributable, in part, to the scene chaos that undoubtedly exists, poor triage and missed diagnosis of blast injuries are substantial concerns because injuries can be subtle or their presentation can be delayed. Management of these injuries can be a challenge, compounded by potentially conflicting treatment goals. This Seminar aims to provide a thorough overview of these unique primary blast injuries and their management.

Abstract
OBJECTIVE The current conflicts in Iraq and Afghanistan have seen frequent use of improvised explosive devices resulting in thousands of casualties, with traumatic brain injuries particularly common. The recent literature is reviewed to provide information to clinicians on the management of this condition. METHOD A Medline search from 2001-2008, using the terms Afghanistan, blast injury, improvised explosive devices, Iraq and traumatic brain injury, was performed. RESULTS The United States military experience predominates in the literature. The use of body armour and other advances has led to improved survival rates among blast injury victims. Resultant neuropsychiatric injuries, in particular traumatic brain injuries, are discussed. There is debate about the prevalence of traumatic brain injuries. The diagnosis, management, relationship with posttraumatic stress disorder and prognosis of traumatic brain injury are reviewed. CONCLUSIONS Traumatic brain injury has been described as the 'signature wound' of the current conflicts in Iraq and Afghanistan. While this term is highly debatable and probably unhelpful, clinicians need to know about this condition to provide the best management.

Abstract
The medical response to a mass casualty further complicates the hectic environment that follows a terrorist event. In addition to providing treatment, medical professionals may discover items or persons of interest to the pending investigation and should be aware of how to handle these situations appropriately. Examples of case law are provided to illustrate how practitioners' actions could help or hinder prosecution. The traditional forensic role of dental professionals is identifying victims through dental records. In this article, the dental professional is considered a member of a disaster response team, and the differences in responsibilities are highlighted.
