Neurosurgeons have limited tools in their armamentarium to visualize critical brain networks during surgical planning. Quicktome was designed using machine-learning to generate robust visualization of important brain networks that can be used with standard neuronavigation to minimize those deficits. We sought to see whether Quicktome could help localize important cerebral networks and tracts during intracerebral surgery. ⋯ Quicktome helps to visualize complex functional connectomic networks and tracts by seamlessly integrating into existing neuronavigation platforms. The added information may assist in reducing neurological deficits and offer explanations for postsurgical outcomes.

Normal pressure hydrocephalus (NPH) has clinical manifestations with different cognitive difficulties. Despite the intense interest, the change in cognitive functions after ventriculoperitoneal shunt (VPS) treatment varies widely. The aims of this study were to monitor the effect of NPH on cognition in elderly and the progress of cognitive abilities after VPS surgery. ⋯ iNPH seems to have a detrimental effect predominantly on EFs. As EFs become corrupted, decline occurs in learning and recall processes of memory. VPS provides an improvement of cognitive deterioration; however, efficacy of this treatment on cognitive abilities is shows in a longer period compared with other iNPH symptoms.

Only a few studies have addressed clinical outcomes of revision surgery for adjacent segment disease. The purpose of this study was to elucidate clinical outcomes of second (repeat) posterior lumbar interbody fusion (PLIF) by focusing on the relationship between clinical outcomes and spinopelvic parameters and predisposing factors requiring subsequent corrective long fusion after repeat PLIF. ⋯ The clinical outcomes of repeat PLIF were inferior to outcomes of primary PLIF. Once PI-LL mismatch occurs after initial PLIF, it will be difficult to resolve the PI-LL mismatch during the second PLIF. To stop the chain of reoperations in patients whose preoperative PI-LL exceeds 27.5° before repeat PLIF, corrective long fusion may be a surgical option to consider.

Instrumented fusion procedures are essential in the treatment of degenerative lumbar spine disease to alleviate pain and improve neurological function, but they are being performed with increasing incidence and variability. We implemented a training module for neurosurgery residents that is based on evidence-based criteria for lumbar fusion surgery and measured its effectiveness in residents' decision making regarding whether patients should or should not undergo instrumented fusion. ⋯ Incorporating a targeted evidence-based learning module for lumbar spine fusion surgery can improve neurosurgery residents' clinical decision making toward a more uniform practice supported by published data.

Sevoflurane (Sev) is a rapidly acting, potent inhalation anesthetic with rapid uptake and elimination. But many studies have shown that Sev could result in cognition dysfunction in adolescent or aging patients. Now, therapeutic targeting with IL-17A antibody has shown a promising effect on Sev-induced cognition impairment. In the study we report that P300 inhibition could act as an alternative approach to decrease IL-17A activity. ⋯ These data show that P300 will potentially be a new drug target for the therapy of cognition impairment caused by Sev.
