Multicenter Study Observational Study
Accuracy of physician-estimated probability of brain injury in children with minor head trauma.
To evaluate the accuracy of physician estimates of the probability of intracranial injury in children with minor head trauma. ⋯ Physician estimates of probability of any brain injury in children were collectively accurate for children with low and moderate degrees of predicted risk. Risk was underestimated in infants.

More than one-half million patients are hospitalized annually for traumatic brain injury (TBI). One-quarter demonstrate sleep-disordered breathing, up to 50% experience insomnia, and half have hypersomnia. Sleep disturbances after TBI may result from injury to sleep-regulating brain tissue, nonspecific neurohormonal responses to systemic injury, ICU environmental interference, and medication side effects. ⋯ Treatment starts with a focus on making the ICU environment conducive to normal sleep. Treating sleep-disordered breathing likely has outcome benefits in TBI. The use of sleep promoting sedative-hypnotics and anxiolytics should be judicious.

Comparative StudyDecreased apparent diffusion coefficient in the pituitary and correlation with hypopituitarism in patients with traumatic brain injury.
The relationship between microstructural abnormality in patients with traumatic brain injury (TBI) and hormone-secreting status remains unknown. In this study, the authors aimed to identify the role of the apparent diffusion coefficient (ADC) using a diffusion-weighted imaging (DWI) technique and to evaluate the association of such changes with hypopituitarism in patients with TBI. ⋯ Use of DWI demonstrated that the pituitary ADC is correlated with hormone-secreting status in TBI patients. The authors suggest that pituitary ADC may be a useful biomarker to predict pituitary function in patients with TBI.

Studies show that there are differences between men and women when it comes to several aspects of health care. But the research on equal care in a prehospital setting for patients with severe traumatic brain injury (TBI) has been sparsely investigated. The aim of this study is to describe prehospital care from a gender perspective. ⋯ Our results show differences, however not significant in the assessments and performed interventions between gender, with female patients receiving more assessments and interventions compared to male patients during prehospital care. Future research should focus on gender differences in initial early signs of TBI to improve early identification.

Comparative Study Observational StudyThe influence of decompressive craniectomy for major stroke on early cerebral perfusion.
Multiple trials have shown improved survival and functional outcome in patients treated with decompressive craniectomy (DC) for brain swelling following major stroke. It has been assumed that decompression induces an improvement in cerebral perfusion. This observational study directly measured cerebral perfusion before and after decompression. ⋯ The presurgical perfusion abnormalities likely reflected local pressure-induced hypoperfusion with impaired autoregulation. The improvement in perfusion after decompression implied an increase in perfusion pressure, likely linked to partial restoration of autoregulation. The increase in perfusion that was observed might partially be responsible for improved clinical outcome following decompressive surgery for major stroke. The predictive value of perfusion CT on outcome needs to be evaluated in larger trials.
