RESUMEN
PRIMARY OBJECTIVE: To assess feasibility and utility of neurocognitive testing of children evaluated and discharged from the ED with mild traumatic brain injury (MTBI). METHODS: Paediatric blunt trauma patients (aged 11-18 years) evaluated in the ED for MTBI and control patients with isolated lower extremity injury were prospectively enrolled. All patients were administered a validated neurocognitive test (ImPACT(©)). Wilcoxon sign rank tests were used to compare reported symptoms and neurocognitive performance between subjects and controls, as well as to matched normative data. RESULTS: Thirty-nine subjects and 46 controls were enrolled. The MTBI patients had a mean age of 13.9 years (53.8% male). An abnormal symptom score was reported in 89.7% of MTBI subjects (mean score = 29.4, normal ≤ 8), differing significantly (p < 0.05) from controls, in whom 39.1% demonstrated an abnormal score (mean score = 8.7). In all neurocognitive test domains, visual motor speed and reaction time, MTBI patients demonstrated lower scores than normative data (p < 0.05). CONCLUSIONS: Patients with MTBI were more likely than control subjects to have scores on any or all neurocognitive domains below the 25th percentile and 10th percentile. In the ED setting, acute neurocognitive testing of MTBI in children is feasible. This highlights the importance of structured follow-up for this treated and released population.

Children are the most frequent victims of dog bites presenting to hospital emergency departments (ED), but there are gaps in understanding of the circumstances of such bites. The objective of this study was to characterise the behavioural circumstances of dog bites by interviewing children ≤17 years (or parent proxies for children ≤6 years) presenting with dog bite injuries to The Children's Hospital of Philadelphia about the bite incident, its setting and associated interactions. Of 203 children enrolled, 51% were <7 years old and 55% were male. 72% of children knew the biting dog. Most bites to younger children occurred during positive interactions, initiated by the child, with stationary, familiar dogs, indoors. Most older bitten children had been active (eg, outdoors), unfamiliar with the dog and not interacting. Whereas face bites predominated (70%) in the younger group (<7 years), bites to extremities predominated (72%) in the older group. Recognition of the two distinctive behavioural and circumstantial subgroups of dog bites that emerged can lead to more effective prevention strategies.
