Spinal cord injury (SCI) triggers a signalling cascade that produces oxidative stress and damages the spinal cord. Voltammetry is a clinically accessible technique to detect, monitor, and guide correction of this potentially reversible secondary injury mechanism. Voltammetry is well suited for clinical translation because the method is inexpensive, simple, rapid, and portable. Voltammetry relies on the measurement of anodic current from a reagent-free, electrochemical reaction on the surface of a small electrode. ⋯ AC measured by CNT-SPE demonstrated a time- and severity-dependent decline after SCI. Plasma AC could serve as a surrogate marker for spinal cord AC.

As the art of neurosurgery evolves in the 21st century, more emphasis is placed on minimally invasive techniques, which require technical precision. Simultaneously, the reduction on training hours continues, and teachers of neurosurgery faces "double jeopardy"-with harder skills to teach and less time to teach them. Mixed reality appears as the neurosurgical educators' natural ally: Virtual reality facilitates the learning of spatial relationships and permits rehearsal of skills, while augmented reality can make procedures safer and more efficient. Little wonder then, that the body of literature on mixed reality in neurosurgery has grown exponentially. ⋯ With parallel advancement in Internet speed and artificial intelligence, the utilization of mixed reality will permeate neurosurgery. From solving staff problems in global neurosurgery, to mitigating the deleterious effect of duty-hour reductions, to improving individual operations, mixed reality will have a positive effect in many aspects of neurosurgery.

Quadrigeminal cistern arachnoid cysts (ACs) are usually asymptomatic, may be accidental findings during radiological evaluation, and are rare (5%-10% of all intracranial ACs). We report a case of type I quadrigeminal cistern AC managed via navigation-guided cystoventriculostomy followed by endoscopic third ventriculostomy (Video 1). A 0° rod-lens endoscope was used. ⋯ Pineal region ACs and associated hydrocephalus can be successfully treated with simple, minimally invasive endoscopic procedures. Navigation assistance may not be necessary in all cases, but it allows for safe, rapid location of the fenestration site. A minimally invasive route and attention to smaller nuances of anatomy are key to safe management of these benign conditions.

To investigate whether financial bias exists in hydrocephalus and vertebral augmentation literature. ⋯ Our findings suggest a positive relationship between reported conflict of interest and positive outcome in neurosurgical literature concerning cerebrospinal fluid valves.
