Trauma-Induced Epilepsy May Be Prevented By Cooling The Brain Following Injury
In the weeks, months and years after a severe head injury, patients often experience epileptic seizures that are difficult to control. A new study in rats suggests that gently cooling the brain after injury may prevent these seizures. "Traumatic head injury is the leading cause of acquired epilepsy in young adults, and in many cases the seizures can't be controlled with medication," says senior author Matthew Smyth, MD, associate professor of neurological surgery and of pediatrics at Washington University School of Medicine in St. Louis...

Timing Matters: Early Post Traumatic Seizures in a Pediatric Population (P01.024)
CONCLUSIONS: EPTS that began >1 hour after injury were related to greater TBI severity, injury mechanism and worse outcomes. Seizures that occurred within the first hour after head trauma were not associated with TBI severity, injury mechanism or worse short-term outcomes. Very early post-TBI seizure events may include impact seizures as well as non-epileptic events (such as brief posturing, syncope, etc), which are distinct from medically observed EPTS and have different prognostic implications.Supported by: National Epifellows Foundation, Thrasher Research Foundation, Today's and Tomorrow's Children Fund, Child Neurol...

Etiologies of pediatric craniofacial injuries: A comparison of injuries involving all-terrain vehicles and golf carts
Conclusions: ATVs and golf carts are often exempt from the safety features and regulations required of motor vehicles, and ATV and golf cart accidents represent a significant portion of pediatric traumas. This study found that ATV and golf cart accidents contribute significantly to craniofacial trauma requiring hospitalization, with resultant morbidity and mortality. Further investigation of these injuries and their prevention in the pediatric population is needed before efforts to promote effective safety regulations for such vehicles in the future can be addressed.

Rear seat child safety in near-side impacts: a modeling study of common sitting positions.
Conclusions: Studies that investigate the injury mitigation effects in common sitting positions, beyond the nominal ATD position, are essential to highlight means to provide improved and robust safety for child occupants. This study was based on the SID-IIs 5th percentile female, which has very similar anthropometry to a 50th percentile 12-year-old. Therefore, the conclusions of this study are applicable to many 11-year-olds up to young adolescents, as well as to small females. The outboard and inboard positions of this study resulted in the highest head injury measures. Although all of the injury measures were only sligh...

Head injury: Audit of a clinical guideline to justify head CT
ConclusionThe study shows that the head injury guidelines are not being fully utilised at a major UK trauma hospital, resulting in 5% of patients being exposed to ionising radiation without apparent documented clinical justification. The NSW guideline has distinct differences to the CG 56, with a more complex algorithm and an absence of specific time frames for head CT completion. The results suggest a need for further education and awareness of head injury clinical guidelines. (Source: Australasian Radiology)

Detecting performance invalidity in children: Not quite as easy as A, B, C, 1, 2, 3 but automatized sequences appears promising.
Abstract In adult populations, embedded performance validity indicators are well established, as they are time efficient, resistant to coaching, and allow for more continuous monitoring of effort than standalone measures. Although several recent studies have demonstrated the appropriateness of using standalone validity tests with school-age children, a paucity of pediatric work has examined embedded indicators. The present study investigated the value of a simple automatized sequences task to detect performance invalidity in 439 clinically referred patients with mild head injury aged 8 through 17 years.
