Auditory dysfunction in traumatic brain injury.
(57/205)
Effective communication is essential for successful rehabilitation, especially in patients with traumatic brain injury (TBI). The authors examined the prevalence and characteristics of auditory dysfunction in patients with TBI who were admitted to a Department of Veterans Affairs TBI inpatient unit before and after the onset of Operation Iraqi Freedom (OIF). In order to delineate the characteristics of the auditory manifestations of patients who had sustained blast-related (BR) TBI, we reviewed the medical records of 252 patients with TBI and categorized them according to admission date, either before (Group I, n = 102) or after (Group II, n = 150) the onset of OIF. We subdivided Group II into non-blast-related (NBR) and BR TBI; no subjects in Group I had BR TBI. We found that admissions for TBI have increased 47% since the onset of OIF. In Group I, 28% of patients with TBI complained of hearing loss and 11% reported tinnitus. In Group II-NBR (n = 108), 44% complained of hearing loss and 18% reported tinnitus. In Group II-BR (n = 42), 62% complained of hearing loss and 38% reported tinnitus. Sensorineural loss was the most prevalent type of hearing loss in Group II-BR patients. In light of the high prevalence of hearing loss and tinnitus in this growing population of returning soldiers, we need to develop and implement strategies for diagnosis and management of these conditions.

Visual function in patients of a polytrauma rehabilitation center: A descriptive study.
(58/205)
Little is known about the visual function deficits associated with polytrauma injury. In this retrospective descriptive study, we examined the records of a clinic established to assess visual function in patients experiencing deployment-related polytrauma. We describe the clinical findings and present a vision examination protocol that may be useful for screening polytrauma patients in other settings. Data from our sample suggested that self-reported vision complaints were common (74%) and confirmed that visual impairment occurred in 38% of all cases. When examining the mechanism of injury, we found that polytrauma due to blast injuries appeared to more than double the risk of visual impairment compared with all other polytrauma causes (i.e., motor vehicle accidents, gunshot and/or shrapnel, assault, falls, or anoxia). The rate of visual impairment in blast-related injury was 52% compared with 20% for all other sources of injury. Visual complaints and impairments were common in the polytrauma patients studied. This finding suggests that comprehensive eye examinations should be routinely administered, particularly when the mechanism of injury involves a blast. (+info)
Traumatic pseudoaneurysms of the head and neck: early endovascular intervention.
(59/205)
BACKGROUND: Trauma to the head and neck with military munitions often presents with complex multisystem injury patterns. Vascular evaluation typically focuses on the carotid and vertebral arteries; however, trauma to branches of the external carotid artery may also result in devastating complications. Pseudoaneurysms are the most frequent finding on delayed evaluation and can result in life-threatening episodes of rebleeding. METHODS: Patients evacuated from the Afghanistan and Iraq conflicts with penetrating injury to the face and neck were evaluated by the vascular surgery service to determine the potential for unsuspected vascular injury. Patients with significant penetrating injury underwent computed tomography angiography (CTA) as the initial evaluation and subsequent arteriography in cases where injuries were suspected or metallic fragments produced artifacts obscuring the vasculature. Data on all vascular evaluations were entered prospectively into a database and retrospectively reviewed. RESULTS: Between February 2003 and March 2007, 124 patients were evaluated for significant penetrating trauma to the head and neck. Thirteen pseudoaneurysms of the head and neck were found in 11 patients: two in the internal carotid artery, one of the vertebral artery, and 10 involving branches of the external carotid. Seven pseudoaneurysms were symptomatic, of which two presented with episodes of massive bleeding and airway compromise. Seven pseudoaneurysms were treated with coil embolization, 1 with Gelfoam (Upjohn, Kalamazoo, Mich) embolization, 2 with stent grafts, 2 with open repair, and 1 with observation alone. None of the patients undergoing embolization had complications; however, a stent graft of the internal carotid artery occluded early, without stroke. All of the pseudoaneurysms had resolved on follow-up CTA or angiogram. CONCLUSIONS: Pseudoaneurysms are a common finding in patients with high-velocity gunshot wounds or blast injuries to the head and neck. Most involve branches of the external carotid artery and can be treated by embolization. CTA should be performed on all patients with high-velocity gunshot wounds or in cases of blast trauma with fragmentation injuries of the head and neck. (+info)

Life or death. The social impact of paramedics and first responders in landmine-infested villages in northern Iraq.
(62/205)
INTRODUCTION: Landmines are indiscriminate weapons that mainly injure poor populations in the developing world. Pre-hospital treatment by village-based paramedics and first responders has reduced mortality, but little is known about the social impact of paramedic and first responder training in villages. The aim of this study was to understand how villagers in socially deprived, mine-infested villages experience the establishment of paramedic and first responder chains of survival. METHODS: The study used focus-group interviews conducted in four villages in northern Iraq, to explore villagers' perceptions of the impact of paramedic and first responder training. The material was analyzed using grounded theory, with the main category identified entitled 'life or death', with three subcategories: 'living on the edge', 'demanding equal rights', and 'adapting to new needs'. RESULTS: The paramedics were perceived by the villagers as having a large impact on the social life of the village, first as an emergency medical resource, and also as a prerequisite for the villages' continued existence. The system represented one of the few services offered by outside society to villages that lacked health care, schools, electricity, roads, and clean water. Despite an improved economic situation in the larger society, conditions in the villages had deteriorated. Although originally intended as an emergency care system for land mine victims, the system was adapted to include the role of a general medical resource in the villages. This adaptation was perceived as useful by the villagers, and necessary for their continued trust in the system. A prerequisite for this adaptation was that the program coordinator was a villager himself, and that the program deviated from its originally fixed time period. This flexibility depended on very close cooperation between expatriate and local program managers. CONCLUSIONS: Our findings indicate that the paramedic system made a wider impact than just the provision of emergency health care. The program earned trust through a strong local anchor, and by adapting to the needs of the population served. (+info)
Injuries from antipersonnel mines: the experience of the International Committee of the Red Cross.
(63/205)
OBJECTIVE: To describe and quantify patterns of injury from antipersonnel mines in terms of distribution of injury, drain on surgical resources, and residual disability. DESIGN: Retrospective analysis. SETTING: Two hospitals for patients injured in war. SUBJECTS: 757 patients with injuries from antipersonnel mines. MAIN OUTCOME MEASURES: Distribution and number of injuries; number of blood transfusions; number of operations; disability. RESULTS: Pattern 1 injury results from standing on a buried mine. These patients usually sustain traumatic amputation of the foot or leg; they use most surgical time and blood and invariably require surgical amputation of one or both lower limbs. Pattern 2 injury is a more random collection of penetrating injuries caused by multiple fragments from a mine triggered near the victim. The lower limb is injured but there is less chance of traumatic amputation or subsequent surgical amputation. Injuries to the head, neck, chest, or abdomen are common. Pattern 3 injury results from handling a mine: the victim sustains severe upper limb injuries with associated face injuries. Eye injuries are common in all groups. CONCLUSIONS: Patients who survive standing on a buried mine have greatest disability. Non-combatants are at risk from these weapons; in developing countries their social and economic prospects after recovery from amputation are poor. (+info)
