Military mild traumatic brain injury (mTBI) differs from civilian injury in important ways. Although mTBI sustained in both military and civilian settings are likely to be underreported, the combat theater presents additional obstacles to reporting and accessing care. ⋯ However, emotional distress appears to figure prominently in symptoms following military mTBI. This review evaluates the extant literature with an eye towards future research directions.

Blunt traumatic occlusion of the internal carotid and vertebral arteries.
The stroke rate, management, and outcome after blunt cerebrovascular occlusion (Biffl Grade IV injury) is not well defined, given the rarity of the disease. Both hemodynamic failure and embolic mechanisms have been implicated in the pathophysiology of subsequent stroke after blunt cerebrovascular occlusion. In this study, the authors evaluated their center's experience with Biffl Grade IV injuries, focusing on elucidating the mechanisms of stroke and their optimal management. ⋯ At the authors' institution, traumatic ICA occlusion is rare but associated with a high stroke rate. Robust collateral circulation may mitigate its severity. Embolic monitoring with TCD ultrasonography and prophylactic antiplatelet therapy should be used in all ICA Biffl Grade IV injuries. Unilateral VA Biffl Grade IV injury is the most common type of traumatic occlusion and is associated with significantly less morbidity. Embolic monitoring using TCD and prophylactic antiplatelet therapy do not appear to be beneficial in patients with traumatic VA occlusion.

ReviewManagement of raised intracranial pressure and hyperosmolar therapy.
The management of raised intracranial pressure is undergoing rapid change. The choice of medical treatments to reduce intracranial pressure varies between institutions and regions of the world. The mainstay of therapy, however, continues to be the infusion of a hyperosmolar solution to achieve an osmotic gradient to force the exit of water from the brain. This review introduces the basic concepts of raised intracranial pressure, summarises several recent studies that have challenged dogma in the field, and provides practical advice on hyperosmolar treatment, based on personal experience and a critical reading of the literature.

The prognostic value of plasma Δ-copeptin levels in patients with isolated traumatic brain injury.
Traumatic brain injury (TBI) is one of the most common causes of death among trauma patients. Earlier prediction of possible poor neurological outcomes, even upon admission to the emergency department, may help to guide treatment. The aim of this prospective study was to assess the predictive value of plasma copeptin levels for early morbidity and mortality in patients with isolated TBI. ⋯ Plasma Δ-copeptin levels may help physicians predict the prognoses of patients suffering from traumatic brain injury.

Serial Plasma DNA Levels as Predictors of Outcome in Acute Traumatic Brain Injury.
Increased plasma deoxyribonucleic acid (DNA) levels may be associated with disease severity after acute traumatic brain injury (TBI). This study posits that increased plasma DNA levels in acute TBI are predictive of outcome. Both serial plasma nuclear DNA (nDNA) and mitochondrial DNA (mtDNA) levels were examined in 88 consecutive patients with acute TBI and 66 control subjects. ⋯ Its levels on presentation were independently associated with outcome and higher levels (cutoff value >72.95 ng/mL) were associated with poorer outcomes. These findings suggest plasma nDNA levels reflect the severity of cerebral damage and can be considered a neuropathologic marker of patients with acute TBI. Further studies with bigger patient populations are warranted for better unbiased comparison.
