Linear skull fracture in infants after mild traumatic brain injury: influence of computed tomography in management. / Fractura lineal de cráneo en el lactante con traumatismo craneoencefálico leve: influencia de la tomografía computarizada en su manejo.

INTRODUCTION: Traumatic brain injury (TBI) is a common reason for pediatric emergency room visits. Surgical intervention for mild TBI is rarely necessary in children aged <2 years, but the intracranial findings can influence the management of the patient. This paper aims to evaluate the impact of computed tomography (CT) in the management of children aged <2 years with mild TBI and linear skull fractures on plain-film X-rays. MATERIAL AND METHODS: This retrospective descriptive study analyzed skull X-rays obtained in children <2 years old attended for mild TBI in the emergency room of our tertiary hospital over a 4-year period. RESULTS: A total of 88 CT studies were done for suspicion of linear skull fractures on plain-film X-rays. Fractures were confirmed in 74, representing a false-positive rate of 16%. Of the 74 infants with confirmed fractures, intracranial CT findings were normal in 68 (92%) and abnormal in 6 (8%). Two patients (2.7% of all patients with confirmed fractures) required hospital stays longer than 2 days; the other four patients with abnormal intracranial findings were discharged within 48hours of admission. None of the cases required surgery. CONCLUSION: Systematic CT studies do not seem justified for all children aged <2 years with TBI and low/intermediate risk of intracranial lesions, even when they have linear skull fractures. In the absence of risk factors, we propose individualizing the imaging study based on clinical criteria.

Neuropsychological alterations and neuroradiological findings in patients with post-traumatic concussion: Results of a pilot study. / Alteraciones neuropsicológicas y hallazgos neurorradiológicos en pacientes con conmoción cerebral postraumática. Resultados de un estudio piloto.

INTRODUCTION: Mild traumatic brain injury (mTBI) has traditionally been considered to cause no significant brain damage since symptoms spontaneously remit after a few days. However, this idea is facing increasing scrutiny. The purpose of this study is to demonstrate the presence of early cognitive alterations in a series of patients with mTBI and to link these findings to different markers of brain damage. METHODS: We conducted a prospective study of a consecutive series of patients with mTBI who were evaluated over a 12-month period. Forty-one (3.7%) of the 1144 included patients had experienced a concussion. Patients underwent a routine clinical evaluation and a brain computed tomography (CT) scan, and were also administered a standardised test for post-concussion symptoms within the first 24hours of mTBI and also 1 to 2 weeks later. The second assessment also included a neuropsychological test battery. The results of these studies were compared to those of a control group of 28 healthy volunteers with similar characteristics. Twenty patients underwent an MRI scan. RESULTS: Verbal memory and learning were the cognitive functions most affected by mTBI. Seven out of the 20 patients with normal CT findings displayed structural alterations on MR images, which were compatible with diffuse axonal injury in 2 cases. CONCLUSIONS: Results from this pilot study suggest that early cognitive alterations and structural brain lesions affect a considerable percentage of patients with post-concussion syndrome following mTBI.

Update in mild traumatic brain injury. / Actualización en el traumatismo craneoencefálico leve.

There has been concern for many years regarding the identification of patients with mild traumatic brain injury (TBI) at high risk of developing an intracranial lesion (IL) that would require neurosurgical intervention. The small percentage of patients with these characteristics and the exceptional mortality associated with mild TBI with IL have led to the high use of resources such as computerised tomography (CT) being reconsidered. The various protocols developed for the management of mild TBI are based on the identification of risk factors for IL, which ultimately allows more selective indication or discarding both the CT application and the hospital stay for neurological monitoring. Finally, progress in the study of brain injury biomarkers with prognostic utility in different clinical categories of TBI has recently been incorporated by several clinical practice guidelines, which has allowed, together with clinical assessment, a more accurate prognostic approach for these patients to be established.

Comparison of the Canadian CT head rule and the New Orleans criteria in patients with minor head injury in a Spanish hospital. / Comparación de la regla canadiense y los criterios de New Orleans en el traumatismo craneal leve en un hospital español.

BACKGROUND AND OBJECTIVE: To compare two scales for assessment of patients with mild head injury. The Canadian CT Head Rule (CCHR) and New Orleans Criteria (NOC) according to their diagnostic accuracy in patients attending an emergency department, and to determine the most important predictive values. METHOD: Cross-sectional study in a first-level Hospital in the period of January 2011 to January 2013. Patients with mild head injury criteria were included. All the patients underwent a computed tomography (CT) of the head as part of internal protocol and the CCHR and NOC criteria were recorded for each patient. We consider the main variable the presence of traumatic lesions on CT and, as secondary variables, neurosurgical intervention and post-concussion syndrome. Sensitivity, specificity, predictive values and validity index (VI) of the CCHR and the NO criteria in the subgroup of patients with a Glasgow Coma Scale (GCS) score of 15 points were compared. RESULTS: A total of 217 patients, of whom 197 had a GCS score of 15 points were evaluated. Both rules showed 100% sensitivity when a significant injury was presented in the CT, the CCHR 100% (95% CI: 97.4%-100%) and the NO criteria 100% (95% CI: 97.4%-100%); but the CCHR achieved higher values of specificity 25.3% (95% CI: 18.6%-32%), positive predictive value (PPV) and VI. The two rules showed a 100% sensitivity regarding neurosurgical intervention; however the CCHR with high-risk criteria showed better specificity, PPV and VI 55.2 (95% CI: 8.3%-62.2%) compared to the NO criteria 7.6 (95% CI: 3.8%-11.5%). With regard to post-concussion syndrome criteria NO criteria showed better sensitivity 100% (95% CI: 96.2%-100%) and predictive values, but lower specificity and VI compared with the CCHR 76.9% (95% CI: 50.2%-100%). CONCLUSIONS: Our study demonstrates the high sensitivity of the CCHR and the NO criteria in patients with mild head injury, both to detect a significant clinical lesion on CT or the need for neurosurgical intervention and better specificity of CCHR compared with NO criteria. The adoption of clinical prediction rules, especially the CCHR, to request a CT scan in patients with mild head injury should be recommended in the emergency department.

Alteraciones neuropsicológicas de la memoria, la atención y el lenguaje en el Síndrome Postraumático Craneal Leve / Neuropsychological alterations of memory, attention and language in Mild Cranial Post Traumatic Syndrome

Resumen Introducción. El traumatismo craneoencefálico (TCE) leve afecta a un gran porcentaje de la población infantil y es un factor etiológico de alteración cerebral que se lo considera sin mayor repercusión en el funcionamiento neuropsicológico de la memoria, atención y lenguaje, ya que en la mayoría de las veces, cuando el niño se encuentra médicamente estable, es dado de alta; no obstante, como se lo presenta en esta investigación, el menor no recuperaría al 100% sus habilidades premórbidas. Método. Se trabajó con un diseño longitudinal de medidas repetidas en una muestra de 30 niños entre 6 y 10 años de edad (Medad = 8.53, SD = 1.45) que sufrieron un TCE y fueron asistidos en un hospital pediátrico de Quito-Ecuador. Se utilizaron como medidas de la memoria, atención y lenguaje pruebas neuropsicológicas de la batería Neuropsi, WISC-IV, TAR y se diseñaron tres escalas de valoración clínica. Resultados. Se encontraron diferencias estadísticamente significativas en los indicadores que valoraron la memoria, atención y lenguaje en los diferentes momentos de medición. Conclusiones. Los datos encontrados sugieren que los niños mejoran en algunas de las áreas neuropsicológicas, no obstante, según el criterio clínico referencial en muchas de ellas no lo hacen completamente. Por otro lado, las escalas de observación diferida, apuntan a que los padres perciben que sus hijos no logran una recuperación completa luego del TCE. Finalmente, se reflexiona sobre la necesidad de brindar un seguimiento neuropsicológico adecuado para que niños que sufren este tipo de TCE puedan recuperarse en el mayor nivel posible.

Introduction. Mild traumatic brain injury (TBI) affects a large percentage of children population; it is an etiologic factor of damage, which is considered without major repercussion in neuropsychological functioning of memory, attention and, language. Sometimes, when children who have suffered TBI are medically stable, they are discharged; however, as it is presented in this research, children would not recover 100% of their premorbid skills. Method. For this study, it was worked with a longitudinal design of repeated measures in a sample of 30 children between 6 and 10 years of age (Mage = 8.53, SD = 1.45), who had suffered a TBI and were assisted in a pediatric hospital from Quito-Ecuador. Neuropsi battery, WISC-IV, and, TAR were used as neuropsychological assessments to obtain measures for memory, attention, and language, plus three clinical assessment scales that were designed as part of this study. Results. Statistically significant differences were found in indicators that assessed memory, attention, and language in different moments of measurement. Conclusions. These data suggest that children improved in some of the neuropsychological areas, however, according to clinical referential criteria, in many of them it was not successfully completed. On the other hand, deferred observation scales suggest that parents perceive their children did not achieve a complete recovery after the TBI. Finally, we reflect on the need to provide adequate neuropsychological monitoring, in order to help children suffering from this type of TBI to recover to the highest possible level.
