  OBJECTIVE The use of intracranial pressure (ICP) monitoring has been postulated to be beneficial in patients with severe traumatic brain injury (TBI), although studies investigating this hypothesis have reported conflicting results. The objective of this study was to evaluate the effect of inserting an ICP monitor on survival in patients with severe TBI. METHODS The Oslo University Hospital trauma registry was searched for the records of all patients admitted between January 1, 2002, and December 31, 2013, who fulfilled the Brain Trauma Foundation criteria for intracranial hypertension and who survived at least 24 hours after admission. The impact of ICP monitoring was investigated using both a logistic regression model and a multiple imputed, propensity score–weighted logistic regression analysis. RESULTS The study involved 1327 patients, in which 757 patients had an ICP monitor implanted. The use of ICP monitors significantly increased in the study period (p < 0.01). The 30-day overall mortality was 24.3% (322 patients), divided into 35.1% (200 patients, 95% confidence interval [CI] 31.3%–39.1%) in the group without an ICP monitor and 16.1% (122 patients, 95% CI 13.6%–18.9%) in the group with an ICP monitor. The impact of ICP monitors on 30-day mortality was found to be beneficial both in the complete case analysis logistic regression model (odds ratio [OR] 0.23, 95% CI 0.16–0.33) and in the adjusted, aggregated, propensity score–weighted imputed data sets (OR 0.22, 95% CI 0.15–0.35; both p < 0.001). The sensitivity analysis indicated that the findings are robust to unmeasured confounders. CONCLUSIONS The authors found that the use of an ICP monitor is significantly associated with improved survival in patients with severe head injury. https://thejns.org/doi/abs/10.3171/2018.7.JNS18270 KEYWORDS traumatic brain injury; Glasgow Coma Scale; ICP monitoring; intracranial pressure

  Evidence indicates that the growth of glioblastoma (GBM), the most common and malignant primary brain cancer, is driven by glioma stem cells (GSCs) resistant to current treatment. As Wnt-signaling is pivotal in stem cell maintenance, we wanted to explore its role in GSCs with the objective of finding distinct signaling mechanisms that could serve as potential therapeutic targets. We compared gene expression in GSCs (n=9) and neural stem cells from the adult human brain (ahNSC; n=3) to identify dysregulated genes in the Wnt signaling pathway. This identified a six-gene Wnt signature present in all nine primary GSC cultures, and the combined expression of three of these genes (SFRP1, SFRP4 and FZD7) reduced median survival of glioma patients from 38 to 17 months. Treatment with recombinant SFRP1 protein in primary cell cultures downregulated nuclear β-catenin and decreased in vitro proliferation and sphere formation in a dose-dependent manner. Furthermore, expressional and functional analysis of SFRP1-treated GSCs revealed that SFRP1 halts cell cycling and induces apoptosis. These observations demonstrate that Wnt signaling is dysregulated in GSC, and that inhibition of the Wnt pathway could serve as a therapeutic strategy in the treatment of GBM.

  BACKGROUND: The existing literature on recurrence rates and long-term clinical outcome after resection of intraspinal nerve sheath tumors is limited. OBJECTIVE: To evaluate progression-free survival, overall survival, and long-term clinical outcome in a consecutive series of 131 patients with symptomatic intraspinal nerve sheath tumors. METHODS: Medical charts were retrospectively reviewed. Surviving patients volun- tarily participated in a clinical history and physical examination that focused on neu- rological function and current tumor status. RESULTS: Follow-up data are 100% complete; median follow-up time was 6.1 years. All patients (100%) had surgery as the first line of treatment; gross total resection was performed in 112 patients (85.5%) and subtotal resection in 19 patients (14.5%). Five- year progression-free survival was 89%. The following risk factors for recurrence were identified: neurofibroma, malignant peripheral nerve sheath tumor, subtotal resection, neurofibromatoses/schwannomatosis, and advancing age at diagnosis. More than 95% of patients had neurological function compatible with an independent life at follow-up. The rate of tumor recurrence in nonneurofibromatosis patients undergoing total resection of a single schwannoma was 3% (3/93), in comparison with a recurrence rate of 32% (12/38) in the remaining patients. CONCLUSION: Gross total resection is the gold standard treatment for patients with intraspinal nerve sheath tumors. In a time of limited health care resources, we rec- ommend that follow-up be focused on the subgroup of patients with a high risk of recurrence. The benefit of long-term, yearly magnetic resonance imaging follow-up with respect to recurrence in nonneurofibromatosis patients undergoing gross total resection of a single schwannoma is, in our opinion, questionable

  BACKGROUND: Traumatic brain injury (TBI) is classified into mild, moderate and severe, based on the Glasgow Coma Score (GCS). However, TBI patients are often influenced by ethanol, which in itself can attenuate the level of consciousness. This study investigated the effect of ethanol on the GCS group classification in TBI patients. METHODS: The Oslo University Hospital trauma database was searched for all patients admitted with a head injury where the blood ethanol concentration (BEC) had been measured (n = 1004). The effect of BEC on GCS groups was analysed using multivariate ordinal logistic regression. RESULTS: This study identified 546, 142 and 316 patients in the mild, moderate and severe groups, respectively. Increasing BEC by 1 g kg(-1) and pre-hospital intubation had OR = 1.34 and 16.34 for being in a more severe GCS group, respectively. Increasing head abbreviated injury scale (head-AIS) was significantly associated with being in a more severe GCS group. The modelled probability of detecting a head-AIS of 4 or 5 in a patient with BEC of 2.0 g kg(-1) was 20%, 38% and 65% in the mild, moderate and severe groups, respectively. CONCLUSIONS: Increasing BEC was associated with increasing odds of being in a more severe GCS group. However, because the modelled probability of significant brain injury was high in patients with high levels of BEC, a reduced level of consciousness in intoxicated patients mandates further radiological investigations.
