Extent of resection (EOR) is well established as correlating with overall survival in patients with glioblastoma (GBM). The impact of EOR on reported quality metrics such as patient safety indicators (PSIs) and hospital-acquired conditions (HACs) is unknown. ⋯ Gross total resection of GBM is associated with a decreased incidence of PSIs and HACs, as compared to subtotal resection.

Resection of deep intracranial cavernous malformations (CMs) is associated with a higher risk of neurological deterioration and uncertainty regarding clinical outcomes. ⋯ Lower preoperative mean FA values for overall and defined CST segments corresponded to worse patient pre- and postoperative motor examination and/or functional status. FA value for the distal ipsilateral CST segment has prognostic potential with respect to clinical outcomes.

The resistivity index (RI) in cerebral venous sinus stenosis (VSS) has not been studied in patients with idiopathic intracranial hypertension (IIH). ⋯ RI calculated using QMRV can serve as a noninvasive tool to aid in the diagnosis of hemodynamically significant VSS. The study had a small sample size, and larger multicenter studies would be required to validate the results further.

Case Reports
Facial Sensory Restoration After Trigeminal Sensory Rhizotomy by Collateral Sprouting From the Occipital Nerves.
Lesioning procedures are effective for trigeminal neuralgia (TN), but late pain recurrence associated with sensory recovery is common. We report a case of recurrence of type 1A TN and recovery of facial sensory function after trigeminal rhizotomy associated with collateral sprouting from upper cervical spinal nerves. ⋯ This is the first documented case of a spinal nerve innervating a cranial dermatome by collateral sprouting after cranial nerve injury. The fact that typical TN pain can occur even when sensation is mediated by spinal nerves suggests that the disorder can be centrally mediated and late failure after lesioning procedures may result from maladaptive reinnervation.

The opioid epidemic continues to worsen with a concomitant increase in opioid-related mortality. In response, the Department of Defense and Veterans Health Agency recommended against the use of long-acting opioids (LAOs) and concurrent use of opioids with benzodiazepines. Subsequently, we eliminated benzodiazepines and LAOs from our postoperative pain control regimen. ⋯ Replacement of benzodiazepines and LAOs in the pain control regimen for single-level TLIFs did not affect pain scores and was associated with decreased opioid use, a reduction in trigger medications, and shorter hospitalizations.
