Multimodal intracranial monitoring is becoming an increasingly common tool in the management of patients with traumatic brain injury. Although numerous reports detailing the benefits of such advanced monitoring exist in the literature, there is minimal discussion of the possible complications that may arise in this patient population. ⋯ To our knowledge, this is the first reported incidence of a subdural empyema developing in this setting. Although the safety profile of multimodal intracranial modeling is excellent, with increasing numbers of invasive bedside procedures, neurosurgeons must remain acutely vigilant for the development of infectious complications.

Rehabilitation modality and onset differentially influence whisker sensory hypersensitivity after diffuse traumatic brain injury in the rat.
As rehabilitation strategies advance as therapeutic interventions, the modality and onset of rehabilitation after traumatic brain injury (TBI) are critical to optimize treatment. Our laboratory has detected and characterized a late-onset, long-lasting sensory hypersensitivity to whisker stimulation in diffuse brain-injured rats; a deficit that is comparable to visual or auditory sensory hypersensitivity in humans with an acquired brain injury. ⋯ These data indicate that modality and onset of sensory rehabilitation can differentially influence FPI and sham rats, having a lasting impact on behavioral and stress responses to the WNT, emphasizing the necessity for continued evaluation of modality and onset of rehabilitation after TBI.

Using Xbox kinect motion capture technology to improve clinical rehabilitation outcomes for balance and cardiovascular health in an individual with chronic TBI.
Motion capture virtual reality-based rehabilitation has become more common. However, therapists face challenges to the implementation of virtual reality (VR) in clinical settings. Use of motion capture technology such as the Xbox Kinect may provide a useful rehabilitation tool for the treatment of postural instability and cardiovascular deconditioning in individuals with chronic severe traumatic brain injury (TBI). The primary purpose of this study was to evaluate the effects of a Kinect-based VR intervention using commercially available motion capture games on balance outcomes for an individual with chronic TBI. The secondary purpose was to assess the feasibility of this intervention for eliciting cardiovascular adaptations. ⋯ Use of a supervised Kinect-based program that incorporated commercial games improved dynamic balance for an individual post severe TBI. Additionally, moderate cardiovascular activity was achieved through motion capture gaming. Further studies appear warranted to determine the potential therapeutic utility of commercial VR games in this patient population.

Simulation of spreading depolarization trajectories in cerebral cortex: Correlation of velocity and susceptibility in patients with aneurysmal subarachnoid hemorrhage.
In many cerebral grey matter structures including the neocortex, spreading depolarization (SD) is the principal mechanism of the near-complete breakdown of the transcellular ion gradients with abrupt water influx into neurons. Accordingly, SDs are abundantly recorded in patients with traumatic brain injury, spontaneous intracerebral hemorrhage, aneurysmal subarachnoid hemorrhage (aSAH) and malignant hemispheric stroke using subdural electrode strips. SD is observed as a large slow potential change, spreading in the cortex at velocities between 2 and 9 mm/min. ⋯ We then correlated variables indicating SD susceptibility with algorithm-estimated SD velocities in twelve aSAH patients. Highly significant correlations supported the algorithm's validity. The trajectory search failed significantly more often for SDs recorded directly over emerging focal brain lesions suggesting in humans similar to animals that the complexity of SD propagation paths increase in tissue undergoing injury.

Traumatic brain injury (TBI) is a critical public health problem worldwide with a significant socioeconomic burden. Although improved safety regulations in high-income countries have resulted in a decline in traffic-related TBI, the incidence of TBI in low-income countries is on the rise. We illustrate the trends and factors involved in TBI in a large Cambodian governmental hospital in Phnom Penh. In addition, suggestions for improvement of the country's road traffic safety are discussed. ⋯ Our study suggests prevention and management of TBIs can have a measurable public health impact in Cambodia. Initiative examples include helmet safety awareness campaigns, stricter penalties, improvement of prehospital care, and more efficient triage. A high proportion of unhelmeted motorcycle accidents correlates with an increase in epidural hematomas.
