Case ReportsPenetrating intracranial wood wounds: clinical limitations of computerized tomography.
The case history of a patient with a periorbital penetrating wooden foreign body is presented. The computerized tomography (CT) densities of several different sources of wood were compared using an experimental model. The clinical usefulness and practical limitations of CT in the evaluation of intracranial foreign bodies is discussed, and the management of this type of injury is reviewed.

Prognostic value of auditory brain-stem responses for late postconcussion symptoms following minor head injury.
Minor head injury is frequently followed by a subjective postconcussion syndrome. Brain-stem auditory evoked responses (BAER's) were found to be pathological in different small series of patients with a postconcussion syndrome who were examined months after sustaining a slight cranial or cervical trauma; abnormal BAER's have also been reported in larger groups of patients examined early after minor head injury. A relationship between these findings and late subjective symptoms has never been demonstrated. ⋯ This study confirms the disturbance of brain-stem function in some head-injured patients. However, the lack of correlation with a postconcussion syndrome limits the prognostic value of BAER recordings for postconcussion syndrome. The data suggest that BAER's not be used for medicolegal evaluation of patients with a postconcussion syndrome.
