Traumatic brain injury (TBI) is a health problem worldwide, and therapeutic strategies to enhance brain tissue repair to lessen neurologic sequels are imperative. We aimed to analyze the impact of the inflammatory process in TBI through CXCR4 and CXCR7 chemokine receptors and their ligands' CXCL11 and CXCL12 expression profile in search for potential new druggable targets. ⋯ The neuroprotective trend of CXCR4, CXCR7, CXCL11, and CXCL12 in TBI observed in this initial analysis warrants further studies with more patients, analyzing the involved signaling pathways for the development of new therapeutic strategies for TBI.

A next-generation networked operating room, Smart Cyber Operating Theater (SCOT), has been developed in cooperation with medical engineers that integrates standalone medical devices, including intraoperative magnetic resonance imaging (MRI) using the OPeLiNK communication interface. Here, we report the application of this newly developed advanced type of operating theater for the endoscopic endonasal approach (EEA), along with an evaluation of our initial experiences. ⋯ SCOT, which is considered an innovative operation system in neurosurgery, enables both quality and safety in the EEA. Furthermore, the use of SCOT may also contribute to the education of young neurosurgeons.

We sought to develop a model to predict the risk of small intracranial aneurysm (SIA; ≤5 mm) rupture among Chinese adults and to compare the score predicted by our model with the PHASES (population, hypertension, age, size, earlier subarachnoid hemorrhage, aneurysm site) score. ⋯ An irregular shape, a high aspect ratio, and a high size ratio were associated with SIA rupture in the Chinese population. Our predictive score is of great value in predicting the risk of SIA rupture.

To elucidate the influence of spondylolysis on age-related lumbar degenerative changes, age-specific lumbopelvic alignment in patients with or without spondylolysis was examined. ⋯ When patients have L5-lysis, lumbar lordosis and pelvic anteversion occurred age dependently. In elderly patients with L5-lysis, L5 vertebral slip with decrease of the L5-S1 angle occurs frequently. The progression of vertebral slip was correlated with atrophy of psoas muscles, but not that of paraspinal extensor muscles.

Various techniques have been performed to reduce subarachnoid clotting during aneurysmal neck clipping surgery. We considered that maintaining the physiologic cerebrospinal fluid circulation by performing arachnoid plasty after clipping during surgery would lead to the accelerated clearance of the subarachnoid clot. ⋯ The present study suggests that good hematoma clearance due to arachnoid formation reduced brain damage, cerebral vasospasm, and hydrocephalus, resulting in significantly fewer cases with poor functional prognosis. It therefore follows that procedures such as arachnoid plasty should be taken into consideration in order to improve outcome in surgical clipping.
