The neuronal biomarker NSE correlates with the volume of lung contusion in polytraumatized patients.
Severe injuries caused by accidents, like traumatic brain injury (TBI) or thoracic trauma (TT) continue to be the leading cause of death in younger people with relevant socio-economic impact. Fast and targeted diagnostics is essential for further therapy decisions and prognosis. The following study investigates NSE as a potential biomarker for lung injury after blunt TT. ⋯ A significant NSE release after isolated thoracic trauma peaks on the day of admission. The extent of lung contusion volume (defined as alveolar parenchymal density) correlates with NSE serum concentration. Thus, NSE has predictive value for the extent of pulmonary contusion. However, according to these data, NSE seems to have no diagnostic value as a TBI biomarker in concomitant TT.

Review Meta Analysis
Cisternostomy as an Adjuvant or Standalone Approach for Management of Traumatic Brain Injury: A Systematic Review and Network Meta-Analysis.
Traumatic brain injury (TBI) is a leading cause of morbidity in all age groups worldwide. Decompressive craniectomy (DC) is a salvage procedure in patients with TBI. The outcome and quality of life following DC is questionable. Basal cisternostomy (BC) has been proposed to reduce edema and lead to brain relaxation. It was initially used as an adjunct in TBI patients, thereby improving outcomes. With gaining popularity among neurosurgeons, BC was used as a standalone approach in TBI patients. This network meta-analysis aims to analyze the role of BC either as an adjunct or as a standalone approach in managing TBI patients. ⋯ Our analysis showed that BC alone was associated with lower in-hospital mortality rates in TBI patients. DC with BC had decreased the requirement of mechanical ventilation. However, larger multi-centric studies from other parts of the world are required to confirm these findings.

Early treatment of elevated intracranial pressure (ICP) is a cornerstone of the therapy in severe traumatic brain injury (TBI) patients. Treatment of refractory high ICP however, remain challenging as only limited and risky third-tier therapeutic interventions are available. Controlled lumbar cerebrospinal fluid (CSF) drainage has been known as an efficient method of ICP reduction after TBI for decades, but it is not recommended in international guidelines because of low evidence background and safety issues. Our centre has a long-standing experience using this intervention for more than 15 years. Here we present our data about the safety and efficacy of controlled lumbar drainage to avoid further second- and third tier ICP lowering therapies and beneficially influence functional outcome. ⋯ Our results support the view that controlled lumbar drainage is a highly efficient method to manage intracranial hypertension and significantly decreases the need of further harmful ICP lowering therapies without altering functional outcome of severe TBI patients.

Comparative Study
Histological comparison of repeated mild weight drop and lateral fluid percussion injury models of traumatic brain injury (TBI) in female and male rats.
In preclinical traumatic brain injury (TBI) research, the animal model should be selected based on the research question and outcome measures of interest. Direct side-by-side comparisons of different injury models are essential for informing such decisions. Here, we used immunohistochemistry to compare the outcomes from two common models of TBI, lateral fluid percussion (LFP) and repeated mild weight drop (rmWD) in adult female and male Wistar rats. ⋯ LFP led to longer-lasting disruptions, perhaps more representative of moderate TBI. We also report that craniotomy and LFP produced greater disruptions in females relative to males. These findings will assist the field in the selection of animal models based on target severity of postinjury outcomes and support the inclusion of both sexes and appropriate control groups.
