چکیده
BACKGROUND : Previous studies indicate that age, Glasgow Coma Scale score (GCS), arterial hypotension, computed tomography (CT) findings, and pupillary reactivity are strong predictors of outcome for patients with severe traumatic brain injury (TBI). However, the predictive validity of these variables has never been rigorously tested in patients from the developing world. The objective of this study was to evaluate the prognostic value of these variables in a resource-limited setting and to test their predictive power by using them to create an outcome model. METHODS : The study was conducted at Hospital Emergencias "Dr. Clemente Alvarez" in Rosario, Argentina. All patients with severe TBI meeting criteria between August 2000 and February 2003 were included. Outcome at 6 months postinjury was measured by mortality and by the Extended Glasgow Outcome Scale score. Two logistic regression models were created for predicting mortality and outcome. RESULTS : Outcome measures were acquired for 100% of the sample (N = 148). There was 58% mortality; 30% had moderate to good recovery, and 12% were severely disabled. The model accurately predicted 83.9% of mortality, and 81.1% of outcome. Because of variation in timing of CT scans, the models were recalculated without the CT variable. The accuracy of prediction was 79.7% and 79% for mortality and Extended Glasgow Outcome Scale, respectively. CONCLUSIONS : This study provides rigorous, prospective data that (1) validates the generalizability of the five World Health Organization/Organization Mondiale de la Santé TBI prognostic predictors outside of the developed world, and (2) provides outcome benchmarks for mortality and morbidity from severe TBI in developing countries.

Identification of Imaging and Clinical Markers Predicting Chronic Sleep Disturbances After Traumatic Brain Injury in Adults
Background and Aim: We aimed to determine the prognostic imaging and clinical markers of chronic Post-Traumatic Sleep-Wake Disorders (PTSWDs) with a special focus on the early cognitive and executive dysfunctions following Traumatic Brain Injury (TBI). The prevalence rate of Post-Traumatic Psychiatric Disorders (PTPDs) in various sleep disorders was also investigated. Methods and Materials/Pat...
متن کاملNon-visible penetrating brain trauma: a case report
Objective: One of the most frequent causes of death and acquired disability in the pediatric population is the Traumatic Brain Injury (TBI). TBI is secondary to falls, road traffic and vehicle collisions, child abuse and assaults. Penetrating brain injury is a severe form of traumatic brain injury. Blunt head injury is more frequent than TBI in children, but the second one carries a poor progno...
متن کاملO 26: Treatment of Traumatic Brain Injury in Adult Rats with Injection of Human Epileptic Neural Stem Cells and Nano-Scaffold
Traumatic brain injury (TBI) is described by a disruption in the normal function of the brain due to an injury following a trauma, which can potentially cause severe physical, cognitive, and emotional impairment. The use of human stem cells and self-assembling peptide scaffolds suggest huge potential for application in the treatment of TBI. In the present study, we surveyed the beneficial effec...
متن کاملNeuroprotective Effects of Allicin on Neurological Scores, Blood Brain Barrier Permeability and Brain Edema Following Severe Traumatic Brain Injury in Male Rats: A Behavioral, Biochemical and Histological Study
Background and purpose: Allicin has a wide range of pharmacological functions, all of which can be demonstrated in anti-inflammatory, antioxidant, antifungal and anti-tumor activities. In this research, we investigated the neuroprotective role of allicin in the process of diffuse traumatic brain injury and its effect on interleukin levels and histological changes in rats. Materials and method...
