Multicenter StudySeverity and outcome of traumatic brain injuries (TBI) with different causes of injury.
Most epidemiological studies and reports have reached a consensus on the leading causes of traumatic brain injury (TBI). Despite the fact that the area of TBI is relatively well studied, reports on differences in severity and outcome of TBI with different causes are lacking. ⋯ It is concluded that the causes of TBI should be considered by both clinicians and public health professionals as a lead in prognosis of outcome and policy planning.

Comparative StudyEmergency department prediction of post-concussive syndrome following mild traumatic brain injury--an international cross-validation study.
Between 20-50% of those suffering a mild traumatic brain injury (MTBI) will suffer symptoms beyond 3 months or post-concussive disorder (PCD). Researchers in Sydney conducted a prospective controlled study which identified that bedside recordings of memory impairment together with recordings of moderate or severe pain could predict those who would suffer PCS with 80% sensitivity and specificity of 76%. ⋯ This is the first study to compare populations from different countries with diverse language groups using a predictive model for identifying PCD following MTBI. The model may be able to identify an 'at risk' population to whom pre-emptive treatment can be offered.

ReviewNon-impact, blast-induced mild TBI and PTSD: concepts and caveats.
A volumetric blood surge (rapid physical movement/displacement of blood) is hypothesized to cause the non-impact, mild TBI and battlefield PTSD induced by a blast over-pressure wave. ⋯ Three factors may be critical to the induction of blast-induced brain injuries: (1) the difference in pressure between the ventral body cavity and cranial cavity; (2) blood that acts as a transmission medium to propagate a pressure wave to the brain; and (3) the vulnerability of cerebral blood vessels and the BBB to a sudden fluctuation in perfusion pressure.

Case ReportsSource imaging of QEEG as a method to detect awareness in a person in vegetative state.
Assessment of awareness in patients with severe brain injury remains subjective, although patients with even limited awareness (e.g. minimal conscious state, MCS) have different prognoses and treatment than those in vegetative state (VS). Recently, task appropriate differential regional activation in VS has been reported using fMRI during mental imagery. ⋯ Results from this single case suggests the potential utility of QEEG source localization images to detect awareness in patients clinically diagnosed as being in VS. This indicates the possibility that EEG may serve as an important adjunct to the assessment of awareness in patients with disorders of consciousness in the clinical setting.

Validation of the Abbreviated Westmead Post-traumatic Amnesia Scale: a brief measure to identify acute cognitive impairment in mild traumatic brain injury.
To validate the use of the Abbreviated Westmead Post-traumatic Amnesia Scale (A-WPTAS) in the assessment of acute cognitive impairment in mild traumatic brain injury (mTBI). ⋯ The A-WPTAS is a valid measure. The A-WPTAS may reduce the risk of failing to classify patients with mTBI by identifying and documenting acute cognitive impairment.
