RESUMO
OBJECTIVE: To examine levels of plasma osteopontin (OPN), a recently described neuroinflammatory biomarker, in children with abusive head trauma (AHT) compared with children with other types of traumatic brain injury (TBI). STUDY DESIGN: The study cohort comprised children aged <4 years diagnosed with TBI and seen in the intensive care unit in a tertiary children's hospital. Patients were classified as having confirmed or suspected AHT or TBI by other mechanisms (eg, motor vehicle accidents), as identified by a Child Protection Team clinician. Serial blood samples were collected at admission and at 24, 48, and 72 hours after admission. Levels of OPN were compared across groups. RESULTS: Of 77 patients identified, 24 had confirmed AHT, 12 had suspected AHT, and 41 had TBI. There were no differences in the Glasgow Coma Scale score between the patients with confirmed AHT and those with suspected AHT and those with TBI (median score, 4.5 vs 4 and 7; P = .39). At admission to the emergency department, OPN levels were significantly higher in children with confirmed AHT compared with the other 2 groups (mean confirmed AHT, 471.5 ng/mL; median suspected AHT, 322.3 ng/mL; mean TBI, 278.0 ng/mL; P = .03). Furthermore, the adjusted mean trajectory levels of OPN were significantly higher in the confirmed AHT group compared with the other 2 groups across all subsequent time points (P = <.01). CONCLUSIONS: OPN is significantly elevated in children with confirmed AHT compared with those with suspected AHT and those with other types of TBI. OPN expression may help identify children with suspected AHT to aid resource stratification and triage of appropriate interventions for children who are potential victims of abuse.

OBJECTIVE: To evaluate the potential impact of a concussion management education program on community-practicing pediatricians. STUDY DESIGN: We prospectively surveyed 210 pediatricians before and 18 months after participation in an evidence-based, concussion education program. Pediatricians were part of a network of 38 clinically integrated practices in metro-Atlanta. Participation was mandatory for at least 1 pediatrician in each practice. We assessed pediatricians' self-reported concussion knowledge, use of guidelines, and comfort level, as well as self-reported referral patterns for computed tomography (CT) and/or emergency department (ED) evaluation of children who sustained concussion. RESULTS: Based on responses from 120 pediatricians participating in the 2 surveys and intervention (response rate, 57.1%), the program had significant positive effects from pre- to postintervention on knowledge of concussions (-0.26 to 0.56 on -3 to +1 scale; P < .001), guideline use (0.73-.06 on 0-6 scale; P < .01), and comfort level in managing concussions (3.76-4.16 on 1-5 scale; P < .01). Posteducation, pediatricians were significantly less likely to self-report referral for CT (1.64-1.07; P < .001) and CT/ED (4.73-3.97; P < .01), but not ED referral alone (3.07-3.09; P = ns). CONCLUSIONS: Adoption of a multifaceted, evidence-based, education program translated into a positive modification of self-reported practice behavior for youth concussion case management. Given the surging demand for community-based youth concussion care, this program can serve as a model for improving the quality of pediatric concussion management.
