The risk of deep vein thrombosis is increased in patients with head trauma, but the prophylaxis against this event is confronted with the possible risk of worsening hemorrhagic injuries. In this article, we present an overview about deep vein thrombosis prophylaxis in patients with head trauma and we propose a practical protocol for clinical management of deep vein thrombosis prophylaxis. ⋯ Head trauma alone is a risk factor for deep vein thrombosis and pulmonary thromboembolism and the risks inherent in this disease requires methods of prevention for these complications. Clinical trials are needed to establish the efficacy of prophylaxis and the best time to start medication for deep vein thrombosis in patients with traumatic brain injury.

Concussions are common injuries with increasing diagnostic incidence. The 4th International Conference on Concussion in Sport, held in November 2012 in Zurich, revised consensus statements regarding the definition of a concussion, diagnostic criteria, and management. ⋯ Rhode Island enacted into law the School and Youth Programs Concussion Act in 2010, which increases awareness of concussions for athletes, coaches, teachers, school nurses and parents/guardians through written information and mandatory training for coaches. Athletes must be removed from practice/competition and cannot return until a physician has evaluated and cleared them.

ReviewFurther understanding of cerebral autoregulation at the bedside: possible implications for future therapy.
Cerebral autoregulation reflects the ability of the brain to keep the cerebral blood flow (CBF) relatively constant despite changes in cerebral perfusion pressure. It is an intrinsic neuroprotective physiological phenomenon often suggested as part of pathophysiological pathways in brain research. ⋯ In this article, we attempt to answer this question by demonstrating how cerebral autoregulation assessment can have prognostic value, indicate pathological states, and potentially even influence therapy with the use of the 'optimal cerebral perfusion pressure' paradigm. Evidence from the literature is combined with bedside clinical examples to address the following fundamental questions about cerebral autoregulation: What is it? How do we measure it? Why is it important? Can we use it as a basis for therapy?

Review Historical ArticleChronic traumatic encephalopathy in professional sports: retrospective and prospective views.
The purposes of this paper are to review: (1) the history of chronic traumatic encephalopathy (CTE) in sports, (2) the similarities and differences between historic and current definitions of CTE, (3) recent epidemiology and cohort studies of CTE and (4) controversies regarding the current CTE positions. ⋯ There are multiple causes of abnormal tau protein deposition in the human brain and the pathogenesis of CTE may not be related solely to concussion and/or sub-concussive injury. In all likelihood, the causes of CTE are a multivariate, as opposed to a univariate, phenomenon.

Developing insight into which factors determine prognosis after traumatic brain injury (TBI) is useful for clinical practice, research, and policy making. Several steps can be identified in prediction research: univariate analysis, multivariable analysis, and the development of prediction models. For each step, several methodological issues should be considered, such as selection/coding of predictors and dealing with missing data. "Traditional" predictors include demographic factors (age), type of injury, clinical severity, second insults, and the presence of structural abnormalities on neuroimaging. ⋯ Prognostic models can be used for providing information to relatives of individual patients, for resource allocation, and to support decisions on treatment. At the group level, prognostic models aid in the characterization of patient populations, are important to clinical trial design and analysis, and importantly, can serve as benchmarks for assessing quality of care. Continued development, refinement, and validation of prognostic models for TBI is required and this should become an ongoing process.
