Time to Follow Commands and Duration of Posttraumatic Amnesia Predict GOS-E Peds Scores 1 to 2 Years After TBI in Children Requiring Inpatient Rehabilitation.
To evaluate the utility of time to follow commands (TFC) in predicting functional outcome after pediatric traumatic brain injury (TBI), as assessed by an outcome measure sensitive to the range of outcomes observed after pediatric TBI, the Glasgow Outcome Scale-Extended, Pediatric Revision (GOS-E Peds). ⋯ Above and beyond the influence of GCS, TFC, PTA, and TFC + PTA are important predictors of later outcome after TBI.

A 40-year-old man suffered severe brain injury and received left side subdural hematoma evacuation with decompressive craniectomy. Intraoperative brain swelling had occurred during the surgery. ⋯ Secondary hematoma evacuation was performed and found a linear fracture near a bleeding meningeal artery. 2 days later CT scan showed cerebral infarction mainly in right posterior cerebral artery distribution. Early diagnosis by postoperative CT scan or other potential ways such as intraoperative sonography is important to prompt treatments and interrupt the pathophysiological chain of the serial attacks.

Retracted PublicationPreferential Protection of Cerebral Autoregulation and Reduction of Hippocampal Necrosis With Norepinephrine After Traumatic Brain Injury in Female Piglets.
Traumatic brain injury contributes to morbidity in children and boys is disproportionately represented. Cerebral autoregulation is impaired after traumatic brain injury, contributing to poor outcome. Cerebral perfusion pressure is often normalized by the use of vasopressors to increase mean arterial pressure. In prior studies, we observed that phenylephrine prevented impairment of autoregulation in female but exacerbated in male piglets after fluid percussion injury. In contrast, dopamine prevented impairment of autoregulation in both sexes after fluid percussion injury, suggesting that pressor choice impacts outcome. The extracellular signal-regulated kinase isoform of mitogen-activated protein kinase produces hemodynamic impairment after fluid percussion injury, but the role of the cytokine interleukin-6 is unknown. We investigated whether norepinephrine sex-dependently protects autoregulation and limits histopathology after fluid percussion injury and the role of extracellular signal-regulated kinase and interleukin-6 in that outcome. ⋯ Norepinephrine protects autoregulation and limits hippocampal neuronal cell necrosis via modulation of extracellular signal-regulated kinase mitogen-activated protein kinase and interleukin-6 after fluid percussion injury in a sex-dependent manner.

On-field management and return-to-play in sports-related concussion in children: Are children managed appropriately?
On-field management and return-to-play guidelines aim to ensure the identification and appropriate management of the concussed athlete. Compliance with current guidelines in many settings is unknown. We assessed whether key components of current concussion guidelines are being followed in child athletes. ⋯ Many children with sports related-concussion are not formally assessed on-field and continue to play. On-field concussion management and return to play practices are often suboptimal. Awareness and education of coaches, teachers, parents and children need to be improved.

Advances in technology have resulted in a plethora of invasive neuromonitoring options for practitioners to manage while caring for the complex needs of the critical care patient. Although many types of invasive neuromonitoring are available to the practitioner, intraparenchymal monitors and external ventricular devices are used most frequently in the clinical setting and are the focus of this article. In addition, multimodality monitoring has been noted to confer a survival benefit in patients with this complex type of invasive neuromonitoring and is discussed as well.
