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.

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.

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.

Balloon-assisted coiling (BAC) is an endovascular treatment that may be associated with increased complications and thromboembolic events compared with other coiling techniques. We compared clinical outcomes of endovascular treatment (simple coiling, stent-assisted coiling, and BAC) in patients with unruptured intracranial aneurysms at the internal carotid artery and assessed risk factors that could cause cerebral infarction in patients who underwent BAC. ⋯ There is a significant association between anatomic ACA variants and cerebral infarction occurrence after BAC. Identifying the variant of the anatomic ACA using digital subtraction angiography would help to predict cerebral infarction after BAC.

Fluorescein sodium (FNa) videoangiography (VA) was performed to evaluate blood flow within vessels and exclusion of the aneurysm after surgical clipping of intracranial aneurysms. The aim of this study was to report results of FNa-VA in a case series, including benefits and limitations of the technique, and compare intraoperative findings with postoperative cerebral angiography to assess reliability of FNa-VA. ⋯ FNa-VA adds greatly to the safety of surgical treatment of intracranial aneurysms, particularly in lesions situated in deep locations, by enabling real-time inspection, which facilitates safer manipulation and evaluation of structures in question.
