In 2010, the Patient Protection and Affordable Care Act was passed to expand health insurance, narrow health care disparities, and improve health care quality in the United States. As part of this initiative, the Agency for Healthcare Research and Quality and the Centers for Medicare and Medicaid Services are now tracking quality metrics. ⋯ Variability exists in the incidence of PSIs and HACs in patients with brain tumors based on insurance status. Controlling for both patient and hospital factors can explain these differences. The cause of these disparities should be studied prospectively to begin the process of improving quality metrics in vulnerable patient populations.

Proximal lesions of the sciatic nerve are often difficult to diagnose and to treat properly. In particular, if there are posttraumatic or postoperative alterations, imaging might not identify the level and location of lesion. Due to the sciatic nerve anatomy, the same is true for clinical and electrophysiological evaluation with a risk of delayed surgery and, thus, unsuccessful surgery. Therefore, in some unclear cases, surgical exploration of the whole sciatic nerve and its divisions could be the only means to determine the correct diagnosis and allow prompt treatment to produce the best clinical outcome. ⋯ The endoscopically assisted single- to multiportal sciatic exploration technique provides excellent visualization that enables nerve inspection, lesion detection, and decompression, and obviates the need for more extensive approaches in cases of unclear sciatic nerve pathology. By adding several ports, whole-length exploration of the sciatic from the notch to fibular head level is feasible.

Intraoperative imaging of cerebral aneurysms may be desirable in emergency situations with large space-occupying hematomas or to visualize vessels after clip placement. Mobile 3-dimensional fluoroscopes are available in a number of neurosurgical departments and may be useful in combination with simple image postprocessing to depict cerebral vessels. ⋯ This technique quickly provides images of adequate quality to assess the configuration of intracranial aneurysms, which may be helpful when immediate intraoperative information about intracranial vessel pathologies is required. The positioning of the fluoroscope, image acquisition, and processing can be completely integrated into the surgical workflow.

Although mirror pain occurs after cordotomy in patients experiencing unilateral pain via a referred pain mechanism, no studies have examined whether this pain mechanism operates in patients who have bilateral pain. ⋯ These results show that a referred pain mechanism causes increased or new pain after cordotomy in patients with bilateral pain. Nevertheless, cordotomy can still be indicated for patients with bilateral pain because postoperative pain is better controlled than the original pain.

Different and often complex routes are available to deal with jugular foramen tumors with extracranial extension. ⋯ The navigation-guided endoscope-assisted extended retrosigmoid inframeatal infratemporal approach provides an efficient and versatile route for resection of jugular foramen tumors with extracranial extension.
