Traumatic brain injury (TBI) is a growing epidemic throughout the world and may present as major global burden in 2020. Some intensive care units throughout the world still have no access to specialized monitoring methods, equipments and other technologies related to intensive care management of these patients; therefore, this review is meant for providing generalized supportive measurement to this subgroup of patients so that evidence based management could minimize or prevent the secondary brain injury. ⋯ There is also a need to develop some evidence based protocols for the health-care sectors, in which there is still lack of specific management related to monitoring methods, equipments and other technical resources. Optimization of physiological parameters, understanding of basic neurocritical care knowledge as well as incorporation of newer guidelines would certainly improve the outcome of the TBI patients.

Maxillofacial injuries comprising hard tissue as well as soft tissue injuries can be associated with traumatic brain injuries due to the impact of forces transmitted through the head and neck. To date, the role of maxillofacial injury on brain injury has not been properly documented with some saying it has a protective function on the brain while others opposing this idea. ⋯ Patients with maxillofacial injuries with or without facial fractures are at risk of acute or delayed traumatic brain injury. All patients should always have proper radiological investigations together with a proper observation and follow-up schedule.

The need for immunosuppression after allo/xenogenic mesenchymal stromal cell (MSC) transplantation is debated. This study compared the long-term effects of human (h) bone marrow MSC transplant in immunocompetent or immunosuppressed traumatic brain injured (TBI) mice. C57Bl/6 male mice were subjected to TBI or sham surgery followed 24 h later by an intracerebroventricular infusion of phosphate buffer saline (PBS, control) or hMSC (150,000/5 μl). ⋯ Five weeks after TBI, hMSC had comparable efficacy, with functional recovery (on both sensorimotor and cognitive deficits) and structural protection (contusion volume, vessel rescue effect, gliotic scar reduction, induction of neurogenesis) in immunosuppressed and immunocompetent mice. Therefore, long-term hMSC efficacy in TBI is not dependent on immunosuppressive treatment. These findings could have important clinical implication since immunosuppression in acute TBI patients may increase their risk of infection and not be tolerated.

Compared to adults, children and adolescents are at greater risk for traumatic brain injury (TBI), with increased severity and prolonged recovery when compared to adults. It is a challenge to provide care for those children who are at risk for complications of TBI under health care resource constraints. ⋯ Acute intracranial injuries among children incur a substantial health care burden. Therefore, health authorities need to optimally allocate medical resources in care.

The effects of different hyperbaric oxygen manipulations in rats after traumatic brain injury.
The protective effects of hyperbaric oxygenation following traumatic brain injury have been widely investigated; however, few studies have made systematic comparisons between the different hyperbaric oxygenation manipulations and their corresponding effects. In this study, male Sprague-Dawley rats were observed at 4h, 15d and 75d after traumatic brain injury. The effects of the different hyperbaric oxygenation manipulations on the rats were compared based on morphological, molecular biological and behavioral tests. ⋯ The effects observed in the hyperbaric oxygen-early group were better than the hyperbaric oxygen-delayed group, and the hyperbaric oxygen-early-delayed group demonstrated the best effects among all the groups. Our results showed the hyperbaric oxygenation was recommended early and delayed post-traumatic brain injury and exposure to hyperbaric oxygenation should be prolonged. These findings provide new ideal therapeutic insight for the clinical treatment of traumatic brain injury.
