The validity of Protein S 100B in Mild Pediatric Head Trauma

Abstract

Background; S100B has been shown to be beneficial as a biomarker in the treatment of adults with mild traumatic brain injury (mTBI). The efficacy of S100B as a biomarker in children, on the other hand, has been a subject of debate. Aim and objectives; was to assess the validity of Protein S 100B in Mild Pediatric Head trauma. Subjects and methods; this was a prospective study, included 160 pediatric patients with mild head trauma presented to Emergency Department. Result; A highly significant correlation between Positive S100B protein and traumatic brain injury with S100B protein value 1554.1±84.0 ng/L. A100 had cutoff value for positive CT Brain finding above 987.5 ng/L, The sensitivity was 81.0%, the specificity was 75%%, the NPV was 86%, the PPV was 68%, and overall accuracy 77%. There was none statistical significant difference regarding severity of brain injury and S100 B (P = 0.225), Conclusion; Serum S100B levels cannot be used to substitute clinical examinations or CT scans in identifying pediatric patients with mild head injuries, but they can be used to identify low-risk kids to avoid excessive radiation exposure.
