Fatal head injury in children: a new approach to scoring axonal and vascular damage.
As part of a multidisciplinary study of brain damage in children fatally injured in motor vehicle accidents, a simple method to quantify and visualise the distribution and extent of injury has been developed. Vascular and axonal injury were assessed using coronal brain sections stained for haematoxylin and eosin, or reacted immunohistochemically for beta-amyloid precursor protein. Subsequent analysis was carried out using NIH Image software, and the resulting information is displayed in schematic diagrams. These summary diagrams simply and clearly show the distribution of injury in both the coronal and horizontal planes. This technique offers an advantage over previous scoring methods in that it provides both a quantitative and a visual summary of the distribution and extent of brain injury. This information can then be used to compare the injury distribution and severity with estimated impact points and acceleration data.
