After traumatic brain injury (TBI), hemorrhagic progression of contusions (HPCs) occurs frequently. However, there is no established predictive score to identify high-risk patients for HPC. ⋯ A simple HPC Score was developed for early risk stratification of HPC in patients with moderate or severe TBI.

Surgical Treatment of Traumatic Intracranial Aneurysms: Experiences at a Single Center over 30 Years.
Traumatic intracranial aneurysm (tIA) is rare and is associated with high rates of morbidity and mortality. We describe our experiences with tIA at our institution. ⋯ tIA is an uncommon complication of head trauma. tIA should be considered when unexpected new symptoms develop in patients with head trauma. Early diagnosis and prompt treatment could help to improve final clinical outcomes.

Historical Article
Ayub Khan Ommaya (1930-2008): Legacy and Contributions to Neurosurgery.
Ayub Khan Ommaya (1930-2008) was a pioneering neurosurgeon of Pakistani origin who is widely known for inventing the Ommaya reservoir, a ventricular catheter with a mushroom-shaped dome for administration of intraventricular therapies. As a Rhodes Scholar at Oxford, Ommaya developed an early interest in studying traumatic brain injury. ⋯ His work on traumatic brain injury led to the creation of the National Center for Injury Prevention and Control, a center for injury prevention research at the Center for Disease Control. This historical paper visits Ommaya's life story and recounts his key contributions to neurosurgery.

How to Train an Injured Brain? A Pilot Feasibility Study of Home-Based Computerized Cognitive Training.
Computerized cognitive training programs have previously shown to be effective in improving cognitive abilities in patients suffering from traumatic brain injury (TBI). These studies often focused on a single cognitive function or required expensive hardware, making it difficult to be used in a home-based environment. This pilot feasibility study aimed to evaluate the feasibility of a newly developed, home-based, computerized cognitive training program for adolescents who suffered from TBI. Additionally, feasibility of study design, procedures, and measurements were examined. ⋯ Our pilot study shows that a longitudinal intervention study comprising our novel, computerized cognitive training program and two follow-up assessments is feasible in adolescents suffering from TBI in the chronic stage. Future studies with larger sample sizes will evaluate training-related effects on cognitive functions and underlying brain structures.

The effect of normobaric hyperoxia on brain oxygenation in the presence or absence of intact autoregulation has not been studied previously in acute traumatic brain injury (TBI). ⋯ In severe TBI, middle cerebral artery CBF velocity is not affected by hyperoxia in both the pathologic and the normal side. The cerebral oxygen saturation increased with increasing arterial hyperoxia in the operated cerebral hemisphere and remained within baseline range in the nonoperated hemisphere. Impairment in the cerebral autoregulation in the pathologic hemisphere contributes to this luxury oxygenation.
