Since traumatic brain injury is the most common cause of long-term disability and death among young adults, it represents an enormous socio-economic and healthcare burden. As a consequence of the primary lesion, a perifocal brain edema develops causing an elevation of the intracranial pressure due to the limited intracranial space. This entails a reduction of the cerebral perfusion pressure and the cerebral blood flow. ⋯ As the irreversible primary lesion can only be inhibited by primary prevention, the therapy of traumatic brain injury focuses on the secondary injuries. The treatment consists of surgical therapy evacuating the space-occupying intracranial lesion and conservative intensive medical care. Due to the complex pathophysiology the therapy of traumatic brain injury should be rapidly performed in a neurosurgical unit.

Observational StudyTherapeutic temperature modulation in severe or moderate traumatic brain injury: a propensity score analysis of data from the Nationwide Japan Neurotrauma Data Bank.
In patients with severe traumatic brain injury (TBI), a randomized controlled trial revealed that outcomes did not significantly improve after therapeutic hypothermia (TH) or normothermia (TN). However, avoiding pyrexia, which is often associated with intracranial disorders, might improve clinical outcomes. The objective of this study was to compare neurological outcomes among patients with moderate and severe TBI after therapeutic temperature modulation (TTM) in the absence of other interventions. ⋯ There was no clear improvement in neurological outcomes after TTM in patients with moderate or severe TBI. To elucidate the role of TTM in patients with these injuries, a prospective study is needed with long-term follow-up using specific target temperatures.

To examine headache and depression over time in individuals who sustained mild traumatic brain injury (mTBI). Prevalence of headache and depression early after mTBI and at 1 year postinjury as well as the relationship between the two are evaluated. ⋯ While prevalence of headache is consistently high over the first year after injury, rate of depression increased over the first year for those who were followed. Given the high rate of comorbidity, those with headache may develop depression over time. Evaluation for possible depression in those with headache after mTBI should be conducted to address both conditions over the year following injury.

Multiple prior studies have suggested an association between survival and beta-blocker administration in patients with severe traumatic brain injury (TBI). However, it is unknown whether this benefit of beta-blockers is dependent on heart rate control. The aim of this study was to assess whether rate control affects survival in patients receiving metoprolol with severe TBI. Our hypothesis was that improved survival from beta-blockade would be associated with a reduction in heart rate. ⋯ Our study shows an association with improved survival in patients with severe TBI receiving metoprolol, and this effect appears to be independent of any reduction in heart rate. We suggest that beta-blockers should be administered to all severe TBI patients irregardless of any perceived beta-blockade effect on heart rate.

S100B and Neuron-Specific Enolase as mortality predictors in patients with severe traumatic brain injury.
To determine temporal profile and prognostic ability of S100B protein and neuron-specific enolase (NSE) for prediction of short/long-term mortality in patients suffering from severe traumatic brain injury (sTBI). ⋯ S100B protein showed higher prognostic capacity than NSE to predict short/long-term mortality in sTBI patients.
