RESUMEN

Firearms injuries have a legal and medico-legal importance, and are especially lethal when they reach the craniofacial regions of the victim. The present study aims to identify the characteristics of craniofacial lesions resulting from firearm projectiles, to register the most affected craniofacial regions by this type of injury and to verify the demographic profile of the victims. A retrospective study was carried out on the autopsy records produced in the first semester of 2015, in five Institutes of Legal Medicine in Porto Velho, situated in the cities of João Pessoa, Vitória, Porto Alegre and Brasília. Data extracted included sex, skin color and age of the victim, craniofacial region reached, shooting distance, shape and size of the injuries and manner of death (homicide, suicide or accident). Based on the 868 reports analyzed, it was possible to observe 1700 entrance lesions of firearm projectiles in craniofacial regions. Among cases of known manner of death, homicides were the most frequent (97.0%). It was observed a higher frequency of male victims (93.3%), mixed race (62.0%), between the ages of 12 and 29 years (59.4%). In all cases considered as suicide or accident there was only one entrance wound, but in 82.8% of the homicides there were multiple gunshot wounds. The craniofacial most affected regions were temporal (25.2%) and occipital (19.8%). The most common sites of projectiles exit were the temporal (25.3%) and parietal (16.1%). All cases of suicide were related to contact shot (69.2%) or close-range shot (30.8%), and among the homicides the distant range shots were more frequent (54.0%). The shape of entrance wounds was mostly circular (56.8%) and oval (31.3%), and among the exit injuries, the lesions were irregular (43.3%) and starry (24.1%). The entrance wounds showed smaller sizes than the exit lesions (p < 0.0001). The data obtained are useful for guiding research that takes into account craniofacial trauma caused by firearm projectiles, makes it possible to compare this data with those of other countries and can base investigative conclusions based on the analyzes discussed in the present work.

RESUMEN

INTRODUCTION: As cities nation-wide combat gun violence, with less than 20% of shots fired reported to police, use of acoustic gunshot sensor (AGS) technology is increasingly common. However, there are no studies to date investigating whether these technologies affect outcomes for victims of gunshot wounds (GSW). We hypothesized that the AGS technology would be associated with decreased prehospital transport time. METHODS: All GSW patients from 2014 to 2016 were collected from our institutional registry and cross-referenced with local police department data regarding times and locations of AGS alerts. Each GSW incident was categorized as related or unrelated to an AGS alert. Admission data, trauma outcomes, and prehospital time were then compared. RESULTS: We analyzed 731 patients. Of these, 192 were AGS-related (26%) and 539 were not (74%). AGS-related patients were more likely to be female (p < 0.01), have a higher injury severity score (ISS) (p < 0.01), and require an operation (p = 0.03). Ventilator days (p < 0.05) and hospital length of stay (p < 0.01) was greater in the AGS cohort. Mortality, however, did not differ between groups (p = 0.5). On multivariable analysis, both total prehospital time and on-scene time were lower in the AGS group (p < 0.01). CONCLUSION: Our study suggests reduced transport times, decreased prehospital and emergency medical service on-scene times with AGS technology. Additionally, despite higher ISS and use of more hospital resources, mortality was similar to non-AGS counterparts. The potential of AGS technology to further decrease prehospital times in the urban setting may provide an opportunity to improve outcomes in trauma patients with penetrating injuries.

RESUMEN

OBJECTIVES: To perform the first direct comparison of the facial injuries sustained and treatment performed at USA and UK deployed medical treatment facilities (MTFs) in support of the military campaigns in Iraq and Afghanistan. SETTING: The US and UK Joint Theatre Trauma Registries were scrutinised for all patients with facial injuries presenting alive to a UK or US deployed MTF between 1 March 2003 and 31 October 2011. PARTICIPANTS: US and UK military personnel, local police, local military and civilians. PRIMARY AND SECONDARY OUTCOME MEASURES: An adjusted multiple logistic regression model was performed using tracheostomy as the primary dependent outcome variable and treatment in a US MTF, US or UK military, mandible fracture and treatment of mandible fracture as independent secondary variables. RESULTS: Facial injuries were identified in 16 944 casualties, with the most common being those to skin/muscle (64%), bone fractures (36%), inner/middle ear (28%) and intraoral damage (11%). Facial injuries were equally likely to undergo surgery in US MTF as UK MTF (OR: 1.06, 95% CI 0.4603 to 1.142, p=0.6656); however, variations were seen in injury type treated. In US MTF, 692/1452 (48%) of mandible fractures were treated by either open or closed reduction compared with 0/167 (0%) in UK MTF (χ2: 113.6; p≤0.0001). US military casualties who had treatment of their mandible fracture (open reduction and internal fixation or mandibulo-maxillary fixation) were less likely to have had a tracheostomy than those who did not undergo stabilisation of the fractured mandible (OR: 0.61, 95% CI 0.44 to 0.86; p=0.0066). CONCLUSIONS: The capability to surgically treat mandible fractures by open or closed reduction should be considered as an integral component of deployed coalition surgical care in the future.

RESUMEN

BACKGROUND: Self-inflicted gunshot wounds involving the face are highly morbid. However, there is a paucity of objective estimates of mortality. This study aims to provide prognostic guidance to clinicians that encounter this uncommon injury. METHODS: A retrospective review of patients presenting to R Adams Cowley Shock Trauma Center (a Level I trauma center) with self-inflicted gunshot wounds to the face from 2007 to 2016. Isolated gunshot wounds to the calvaria or neck were excluded. The data were analyzed to determine predictors of survival. RESULTS: Of the 69 patients that met inclusion criteria, 90 percent were male and 80 percent were Caucasian, with an age range of 21 to 85 years. The most frequently seen injury patterns showed submental (57 percent), intraoral (22 percent), and temporal (12 percent) entry sites. Fewer than half (41 percent) of the cohort sustained penetrative brain injury. Overall, there were 18 deaths (overall mortality, 26 percent), 17 of which were secondary to brain injury. Independent predictors of death included penetrative brain injury (OR, 17; p < 0.0001) and age. Mortality was 17 percent among patients younger than 65 years, compared with 73 percent for those aged 65 years or older (p = 0.0001). Gastrostomy placement was independently associated with 25 percent reduction in length of hospitalization (p = 0.0003). CONCLUSIONS: Despite tremendous morbidity, the overwhelming majority of patients who present with facial self-inflicted gunshot wounds will survive, especially if they are young and have no penetrative brain injury. These findings should help guide clinical decisions for this devastating injury. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

RESUMEN

BACKGROUND: In Spain, the number of aged persons is increasing. By the year 2066, it is expected that 34.6% of the Spanish population will be over 65 years of age. Elderly people present a higher burning risk owing in part to impaired balance and decreased physical strength, lower cognitive abilities, or socioeconomic context. OBJECTIVE: Burns to the upper body body are common and affect both emotional state and physical function, thus leading to reduced quality of life (QoL). Our objective was to determine the influence of age on the QoL of patients who experienced burns to the upper body, with burns with 2 years. METHODS: This is an observational study with a sample of 58 patients with burns only on the upper body. Patients were divided into two groups: 29 patients of age over 65 years and 29 patients under 65 years; all of them attended the Vall d'Hebron Burn Center, Barcelona, between 2011 and 2014. From the original sample, 45 patients had survived by the time the information was gathered. The QoL of these individuals was evaluated with the Spanish version of the Burn Specific Health Scale. Demographic data (sex, age, total burn surface area [TBSA], burn mechanism, pathological history, length of hospital stay, and rehabilitation duration) were collected. Statistical analysis included parametric and nonparametric tests as appropriate with R3.3.3. RESULTS: There were no differences between groups regarding the mechanism of burn, TBSA, length of hospital stay, and the domains of QoL test. High blood pressure, diabetes, and other comorbidities were significantly more common in the elderly group than in the younger group. Eleven patients died in the elderly group and two in the younger group (p=0.012). CONCLUSION: As opposed to what could be expected, in this study, there were no significant differences between surviving patients in both age groups in terms of perceived QoL. Nevertheless, mortality after a burn in the upper side of the body was significantly higher in elderly people than in younger people. The present study results do not support the use of different rehabilitation approaches in elderly patients.

RESUMEN

El estudio de las muertes por arma de fuego, en sus distintas etiologías, forma parte de la práctica habitual medicoforense. En aquellas de origen suicida, la boca constituye un lugar preferente para el disparo, de forma contraria a los supuestos homicidas o accidentales. En el presente trabajo se revisan distintas variables de utilidad para la determinación medicoforense de la etiología, con especial referencia a los disparos intraorales. Entre ellas se analizan el lugar del suceso, tipo de arma empleada, el número y localización de las heridas, el trayecto seguido por el proyectil y las lesiones ocasionadas, siendo de especial interés la forma en que resultan afectados los labios, los dientes y la lengua. Para lo cual se ha realizado una búsqueda, incluyendo las bases de datos bibliográficas PubMed, Dialnet y Google Académico (AU)


Investigation of deaths caused by the use of firearms, with their different homicidal, suicidal and accidental etiologies, is part of the medical-forensic expert's regular work. Mouth is usually chosen by the suicide using a gun. However, gunshot rarely occurs -or it is an exception, in homicidal or accidental deaths. In this paper we shall review the different variables which are useful in order to discriminate the different etiologies, such as the scene, the kind of weapon used, the number of injuries sustained and their location, or the direction of the bullet. Also, we shall particularly focus on the types of injuries caused. The way that lips, teeth and tongue are affected is of particular interest in this investigation. For this purpose, we have conducted a research in books and medical articles, including the PubMed, Dialnet y Academic Google bibliographic database (AU)

RESUMEN

OBJECTIVES: The objective of this study was to identify the characteristics related to crash and victim, as well as the after-effects/disabilities and consequences arising from traffic crashes occurring in the city of Rio Branco-Acre. METHODS: This is an analytical descriptive cross-sectional study conducted in the City of Rio Branco-Acre. The study population consisted of 405 residents of the city who were victims of traffic crashes, of all age groups and genders, who were hospitalized for the first time as a result of the crash in public hospitals and the health system network, as recorded in the Hospital Information System, and who were discharged between January 1 and December 31, 2010. The data sources included hospital record consultations and active searches for the victims. Hierarchical logistic regression was performed to evaluate the factors associated with the after-effects. RESULTS: The majority of the study population was motorcycle victims (68.6%), male, and young (20-39 years). Concerning the after-effects, the following were significantly associated: factors related to the presence of a postcrash activity limitation (odds ratio [OR] = 2.39; 95% confidence interval [CI], 2.39-6.76), length of hospital stay in days (OR = 1 03; 95% CI, 1.01-1.06), and surgical treatment (OR = 1.82; 95% CI, 1.03-3.21). Those who suffered damage to soft tissue and nerves or facial injury showed an odds ratio of 2 to 4 times of having an after-effect/disability, independent of the victim's personal attributes. CONCLUSION: The mechanism, such as the origin of the pattern of injuries, explains the exposure factors shown by each attribute of the victim and their characteristics. Many of the injuries were precursors to after-effects/disabilities, which, due to their nature and extent, result in the modification of the apparently healthy living standards of young victims who are routinely injured in traffic crashes. Therefore, public policies for prevention should be formulated, reformulated, and implemented, taking into account each attribute of the victims and their social conditions, because these are closely related to their habits and customs. This is a starting point for promoting changes to the current reality that traffic crashes present in the morbidity and mortality of the population.

RESUMEN

INTRODUCTION: In Malaysia, motorcyclists continue to outnumber other road users in injuries and deaths. The objective of this study was to determine the association between helmet fixation and helmet type with head injury and severity of head injury among Malaysian motorcyclists. METHODS: The study design was a prospective cross-sectional study. The participants involved injured motorcyclists who were admitted in five selected hospitals in Klang Valley, Malaysia. Participants who sustained head injury were selected as the cases while those with injury below the neck (IBN) were selected as the controls. Questionnaire comprising motorcyclist, vehicle, helmet and crash factors was examined. Diagnoses of injuries were obtained from the participants' medical records. RESULTS: The total subjects with head injuries were 404 while those with IBN were 235. Majority of the cases (76.2%) and controls (80.4%) wore the half-head and open-face helmets, followed by the tropical helmets (5.4% and 6.0% of the cases and controls, respectively). Full-face helmets were used by 1.2% of the cases and 4.7% of the controls. 5.7% of the cases and 6.0% of the controls did not wear a helmet. 32.7% of the cases and 77.4% of the controls had their helmets fixed. Motorcyclists with ejected helmets were five times as likely to sustain head injury [adjusted odds ratio, AOR 5.73 (95% CI 3.38-9.73)] and four times as likely to sustain severe head injury [AOR of 4.83 (95% CI 2.76-8.45)]. The half head and open face helmets had AOR of 0.24 (95% CI 0.10-0.56) for severe head injury when compared to motorcyclists who did not wear a helmet. CONCLUSION: Helmet fixation is more effective than helmet type in providing protection to the motorcyclists.

RESUMEN

PURPOSE: Retrospective studies on the types and causes of facial burns are important because the patterns might vary in different societies. Our aim was to assess the burn-related factors of significance that might be useful in healthcare planning and implementing preventive strategies, adding to the body of current data on the subject. MATERIALS AND METHODS: A retrospective cross-sectional study was conducted to assess the data from a major burns referral center during a 5-year period (2009 to 2013). The data relevant to age, gender, cause, source, location, burn degree, extent (body surface area [BSA]) of the burns, and mortality were gathered from comprehensive patient medical records, recorded, and analyzed using SPSS, version 20, software (SPSS, Chicago, IL). RESULTS: Within the study period, we found 808 documented cases of second- and third-degree facial burns. These burns were more common in men (81.9%) and in the 16- to 35-year age group (42.3%). The mean hospitalization was 9.85 ± 8.94 days. In 443 patients (54.83%), 10 to 19% of their BSA was burned, and 3.06% had associated inhalation burns. The most common burn was scalding (19%), and the deadliest was burns from acid, with a mortality rate of 7.4%. Accidents accounted for 776 burns (96.03%). Other causes were attempted homicide (16 cases, 1.98%) and suicide attempts (16 cases, 1.98%). The overall mortality was 1.6%. CONCLUSIONS: The key findings were that second- and third-degree facial burns were more common in males aged 16 to 35 years with burns covering 10 to 19% of the BSA. Accidental scalding was commonly responsible for the second-degree burns, and electrical accidents were commonly responsible for third-degree facial burns. Burn accidents occurred more often at the patient's home.

RESUMEN

It is important to improve the medical care system and treatment of victims, introduce new methods of treatment and attract the multidisciplinary specialists in the cases of multitrauma. An integrated approach is required for the identification of different character and severity of multiple craniofacial injuries and the development of rational surgical strategy on this base. Different scales such as AIS, CRIS, ISS, PTS, TRISS, TRISSCAN, CRAMS et.al, were created abroad. Another approach to medical strategy was developed in the department of military surgery of Kirov Military Academy in the late nineties. It was based on investigating of possibilities of surgical strategy optimization by application of objective evaluation of the severity of injuries (military surgery--SP, SG, SS). Given treatment strategy of victims with multiple craniofacial trauma resulted in double reduction of quantity of suppurative and septic complications (from 10.5% to 4.1%). It gave the possibility to reduce the lethality from 6.4% to 4.0%. At the same time a hospital stay was shortened and the strategy allowed obtaining satisfactory functional results of treatment and avoiding reinterventions for removal of posttraumatic facial deformations.

RESUMEN

BACKGROUND: Gunshot wounds and blast injuries to the face (GSWBIFs) produce complex wounds requiring management by multiple surgical specialties. Previous work is limited to single institution reports with little information on processes of care or outcome. We sought to determine those factors associated with hospital complications and mortality. METHODS: We performed an 11-year multicenter retrospective cohort analysis of patients sustaining GSWBIF. The face, defined as the area anterior to the external auditory meatuses from the top of the forehead to the chin, was categorized into three zones: I, the chin to the base of the nose; II, the base of the nose to the eyebrows; III, above the brows. We analyzed the effect of multiple factors on outcome. RESULTS: From January 1, 2000, to December 31, 2010, we treated 720 patients with GSWBIF (539 males, 75%), with a median age of 29 years. The wounding agent was handgun in 41%, explosive (shotgun and blast) in 20%, rifle in 6%, and unknown in 33%. Prehospital or resuscitative phase airway was required in 236 patients (33%). Definitive care was rendered by multiple specialties in 271 patients (38%). Overall, 185 patients died (26%), 146 (79%) within 48 hours. Of the 481 patients hospitalized greater than 48 hours, 184 had at least one complication (38%). Factors significantly associated with any of a total of 207 complications were total number of operations (p < 0.001), Revised Trauma Score (RTS, p < 0.001), and head Abbreviated Injury Scale (AIS) score (p < 0.05). Factors significantly associated with mortality were RTS (p < 0.001), head AIS score (p < 0.001), total number of operations (p < 0.001), and age (p < 0.05). An injury located in Zone III was independently associated with mortality (p < 0.001). CONCLUSION: GSWBIFs have high mortality and are associated with significant morbidity. The multispecialty involvement required for definitive care necessitates triage to a trauma center and underscores the need for an organized approach and the development of effective guidelines. LEVEL OF EVIDENCE: Therapeutic/care management, level III.

RESUMEN

The present study is a retrospective analysis of 13 cases of deaths, which resulted from throwing of corrosives over the body. The cases were autopsied at the Department of Forensic Medicine, Maulana Azad Medical College & Associated Hospitals, Delhi, India, during a period of 13 years from July 1998 to June 2011. The cases represented approximately 0.1% of all autopsy cases during the same period. Data were analyzed with regard to the age, sex, place of occurrence, pattern of injury, survival period, and cause of death. Of these cases, 8 (61.54%) were male, and 5 (38.46%) were female. The most common age group of the victim was 21 to 30 years (46.15%). Six of the victims were attacked on the road side. Face and thorax were involved in all cases (100%). The average total body surface area of burn was 56.69%.The mean survival period was 28.2 days. In 53.85% of cases, the cause of death was septicemia.

RESUMEN

Citizens of the United States own more firearms than those in any other country, and the majority of the firearms owned are handguns. Given such prevalence, surprisingly few studies have been published describing the characteristics of deaths due to handguns. To address this gap, nonaccidental handgun deaths examined at the Bexar County Medical Examiner's Office between 2000 and 2010 were reviewed. A total of 1450 cases were identified, including 797 suicides and 653 homicides. Age, range of fire, location of wound, and manner of death were analyzed. The average age of suicide victims (46.7 years) was found to be greater than that of homicides (34.3 years). Suicidal wounds tended to be contact wounds to the head; abdominal, extremity, back, and multiple wound locations were more common in homicides as were distant and intermediate wounds. Handgun wounds to the forehead, side of head, submental, and intraoral locations were significantly more common in suicide, whereas those to the face, apex of the head, and back of the head were more common in homicides. Where possible, likelihood ratios were calculated to determine relative likelihood of suicide or homicide for specific wound locations and ranges. While each death should be analyzed based on its unique circumstances and not solely its statistical probability, these data may help inform the pathologist's conclusions.

RESUMEN

The authors reviewed their 10-year experience of performing face grafts in children with burns. They sought to compare different methods for aesthetic outcome and need for reconstruction. In addition, they determined the efficacy of using allograft skin or Integra as temporary covers. They performed a review of 160 pediatric patients who underwent acute facial excision and grafting for burns between 2000 and 2010. Of the 160 patients with a mean age of 5.8 ± 4.8 years, 96 were males. The mean burn size was 39.4 ± 24.61%, of which 36.5 ± 25.4% was third degree. Overall length of stay was 72.1 days, intensive care unit length of stay was 44.2 days, and the mortality rate was 13.75%. Ninety patients had their entire face burned, 42 burned half, 15 burned their foreheads, and seven had other combinations. The interval between injury and grafting was 13.9 ± 13.19 days. Sixty-three percent patients required one face graft, 23% had two, 8% had three, and 6% four or more. For their initial procedure, 105 patients underwent autografting, 28 had allografting, and 23 received Integra. The authors performed a two-stage procedure in 20.4% and a 1-day procedure in 79.6%. Ten patients had a contiguous "U-shaped" graft wrapped around the face. At least partial regrafting was performed in 21.1%. Allograft and Integra were used for massive burns (69.9 ± 14.5%, 62.6 ± 18.3%, respectively). Of these, 39% died, 17% developed an Integra infection, and 43% required regrafting before autografting. Overall, 24.5% of patients underwent facial reconstruction during their first admission, and 57.1% during subsequent admissions. No difference in the rate of reconstructive surgery was noted between patients receiving Integra or autografting. Autografting face burns as an initial, one-stage procedure works well. The "wrap-around" autograft leads to excellent cosmetic results. When there is a shortage of autograft, allograft or Integra are good options but Integra does not reduce the need for reconstructive surgery.

RESUMEN

BACKGROUND: Gunshot wounds to the face (GSWF) may produce life-threatening injuries. Our objective is to describe outcomes of and factors related to interventions for urgent airway control (UAC) and urgent bleeding control (UBC) as well as to analyze complications associated with GSWF. METHODS: This was a retrospective study of 155 GSWF patients who were admitted to two Level 1 academic trauma centers over an 11-year period. Demographic details, injuries sustained, interventions performed, and timing of the interventions were recorded. Morbidity and mortality data were evaluated. RESULTS: Overall, 115 (74 %) patients suffered isolated GSWF, and none died. Of the 90 (58 %) patients requiring UAC, only three had a cricothyroidotomy. Of the 41 (26 %) patients requiring UBC, only four had angiographic embolization. Intraoral involvement and extrafacial injuries were associated with both UAC and UBC. Overall, 75 patients (48 %) required operations on the bones, eyes, or both. Complications developed in 14 and were treated successfully. CONCLUSIONS: UAC and UBC are required frequently after GSWF and are associated with intraoral involvement and injuries beyond the face. Simple methods, such as orotracheal intubation and packing, are typically sufficient for successful management. About half of the patients need further surgery, with infrequent morbidity.

RESUMEN

BACKGROUND: According to US military data, airway obstruction is the third leading cause of possibly preventable death in combat. In the absence of law enforcement-specific medical training, military experience has been translated to the law enforcement sector. The purpose of this study was to determine whether airway obstruction represents a significant cause of possibly preventable death in police officers, and whether current military combat lifesaver training programs might have prevented these fatalities. METHODS: De-identified, open-source US Federal Bureau of Investigation (FBI) Uniform Crime Report Law Enforcement Officers Killed and Assaulted (LEOKA) data for the years 1998-2007 were reviewed. Cases were included if officers were on duty at the time of fatal injury and died within one hour from time of wounding from penetrating face or neck trauma. After case identification, letters requesting autopsy reports were sent to the departments of victim officers. Reports were abstracted into a Microsoft Excel database. RESULTS: During the study period, 42 of 533 victim officers met inclusion criteria. Departmental response rate was 85.7%. Autopsy reports were provided for 29 officers; 23 (54.8%) cases remained in the final analysis. All officers died from gunshot wounds. No coroner specifically identified airway obstruction as either a direct cause of death or contributing factor. Based upon autopsy findings, three of 341 officers possibly succumbed to airway trauma (0.9%; 95% CI, 0.0%-1.9%). Endotracheal intubation was the most common advanced airway management technique utilized during attempted resuscitation. CONCLUSION: The limited LEOKA data suggests that acute airway obstruction secondary to penetrating trauma appears to be a rare cause of possibly preventable death in police officers. Based upon the nature of airway trauma, nasopharyngeal airways would not be expected to be an effective lifesaving intervention. This study highlights the requirement for a comprehensive mortality and "near miss" database for law enforcement officers.

RESUMEN

OBJECTIVE: Define the number and type of facial and penetrating neck trauma injuries sustained in Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF). STUDY DESIGN: Retrospective database study. SETTING: Tertiary care level I trauma center. SUBJECTS AND METHODS: The Joint Theater Trauma Registry (JTTR) was queried for data from OIF and OEF from January 2003 to May 2011. Information on demographics; type and severity of facial, neck, and associated trauma injures; and impact on overall mortality was recorded. RESULTS: There were 37,523 discrete facial and penetrating neck injuries that occurred in 7177 service members. There were 25,834 soft tissue injuries and 11,689 facial fractures. The most common soft injury sites were the face/cheek (48%), neck/larynx/trachea (17%), and mouth/lip (12%). The maxilla (25%), mandible (21%), and orbit (19%) were the most common facial fracture sites. The most common mechanism of injury was penetrating (49.1%), followed by blunt (25.7%), blast (24.2%), and other/unknown/burn (1%). Injuries were associated with an overall mortality rate of 3.5%. The highest risks for mortality were treatment at a level IIa facility, female sex, prehospital intubation, and blast injury. Most injuries were mild to moderate. CONCLUSION: Facial and penetrating neck trauma are common in modern warfare. Most injuries are minor to moderate and survivable. Training and potential body armor updates can be made. Medical personnel deploying to support OIF and OEF could benefit from specific training in the management of facial and penetrating neck injuries. A surgeon skilled in managing these injuries would likely be beneficial in a deployed setting.
