To examine the frequency of acute mild traumatic brain injury (mTBI) symptoms in children using a concussion symptom inventory and to identify which symptoms are most useful in identifying mTBI. It was hypothesized that symptoms associated with mTBI are more common in children with head injury than orthopaedic injury and certain symptoms are more useful than others in identifying mTBI. Research design: Prospective case-control study conducted in a paediatric trauma centre emergency department.
Children of 6-18 years old with head injury or a minor extremity injury were enrolled. Symptoms were assessed using a graded symptom checklist. Symptom frequency was compared using a chi-square test. The association between individual symptoms with AMS was evaluated with logistic regression analysis.
Children with head injury displayed more frequent symptoms than controls. Head-injured cases with altered mental status (AMS) demonstrated the most frequent and severe symptoms (median symptom scores: control = 1, cases without AMS = 5, cases with AMS = 10; p < 0.001). Headache, nausea, dizziness, blurred/double vision and not feeling 'sharp' were associated with AMS.
Symptoms associated with mTBI are more frequent in children with head injury. AMS magnifies this effect. A symptom inventory is integral to the evaluation of mTBI in children; a smaller set of dichotomized symptoms may be as useful as and more easily administered than lengthier symptom scales.

    ABSTRACT: Concussion (mild traumatic brain injury (mTBI)) is a significant pediatric public health concern. Despite increased awareness, a comprehensive understanding of the acute and chronic effects of concussion on central nervous system structure and function remains incomplete. Here we review the definition, epidemiology, and sequelae of concussion within the developing brain, during childhood and adolescence, with current data derived from studies of pathophysiology and neuroimaging. These findings may contribute to a better understanding of the neurological consequences of traumatic brain injuries, which in turn, may lead to the development of brain biomarkers to improve identification, management and prognosis of pediatric patients suffering from concussion.

    ABSTRACT: A sharp increase in the number of diagnosed concussions has been observed for the traditional adultathlete, as well as the young recreational athlete. An enhancing awareness and growing concern has been noted for the potentially larger number of concussions that go undiagnosed and the unknown capability for long-term complications associated with this injury. This increase in concussion awareness has appropriately led to an enhanced utilization of the health-care system for concussion evaluation and management. As is always the case in the practice of medicine, it is important for healthcare providers, from all points of entry in the healthcare system, to provide consistent management for the best outcomes for any disease process. Millions of sport-related concussions occur each year in the United States, placing a large demand on the healthcare system. Utilization of appropriate and congruent treatment plans during the medical discourse when transferring care of patients between providers is paramount. In the co-management model of care, subspecialists lend expertise to assist primary-care providers (PCPs) in gaining the core competencies necessary to provide appropriate levels of care for certain conditions. Increased use of co-management could make the health-care system more efficient and collaborative, leading to: increased access for patients, lower overall costs, and improved quality of care and health outcomes. Co-management allows patients and families to have access to the expert knowledge of subspecialist while receiving more of their care from their PCP, increasing their comfort and making treatment more convenient. The intent of this paper is to distribute an algorithm created by a multidisciplinary group of medical providers to provide a rational approach, congruent with the standard of care, for the primary-care provider to institute an individualized stepwise progression.

    ABSTRACT: Historically, research to explore traumatic brain injury (TBI) has focused on blunt head trauma, particularly as associated with severe con-sequences. In this injury pattern, treatment focuses on initial life-saving measurements, intensive care in the hospital, and rehabili-tating activities of daily living. 1,2 Far less at-tention has been focused on mild traumatic brain injury (mTBI). Until recently, mild head injury was eas-ily written off as "just a concussion" and patients were assured that their symptoms would "resolve with time." New attention to injuries sustained by professional ath-letes and military service members has un-derscored the need for greater attention to head injuries in general and to mTBI/con-cussion in particular. Despite increased in-terest in this area, the chronic consequences of mTBI are largely unknown and unpre-dictable. Injury patterns can include central nervous system sequelae, as well as direct and indirect central influences on peripheral sense organs. There is currently no research frame-work sufficient to examine the full impact of brain injury on all affected systems, in-cluding potential effects of treatment and rehabilitation of any one system on mul-tiple others. These are pressing questions to address the needs of blast-related TBI patients in whom multiple injury scenarios are typical. Current reports estimate that blast exposures and subsequent mTBI ac-count for 85% of all battlefield injuries. The Department of Defense (DoD) and the Defense Veterans Brain Injury Center esti-mate that as many as two-thirds of medical Neurosensory Sequelae of Mild Traumatic Brain Injury 1. Understand the pathophysiology of neurosensory sequelae of mild traumatic brain injury. 2. Understand treatment options for the neurosensory sequelae of mild traumatic brain injury. 3. Understand the interactions of neurosensory sequelae in patients with mild trau-matic brain injury.
