Serum S100B Levels Can Predict Computed Tomography Findings in Paediatric Patients with Mild Head Injury

Introduction. Traumatic brain injuries (TBIs) are very common in paediatric populations, in which they are also a leading cause of death. Computed tomography (CT) overuse in these populations results in ionization radiation exposure, which can lead to lethal malignancies. The aims of this study were to investigate the accuracy of serum S100B levels with respect to the detection of cranial injury in children with mild TBI and to determine whether decisions regarding the performance of CT can be made based on biomarker levels alone. Materials and Methods. This was a single-center prospective cohort study that was carried out from December 2016 to December 2017. A total of 80 children with mild TBI who met the inclusion criteria were included in the study. The patients were between 2 and 16 years of age. We determined S100B protein levels and performed head CTs in all the patients. Results. Patients with cranial injury, as detected by CT, had higher S100B protein levels than those without cranial injury . We found that patients with cranial injury (head CT
