The effectiveness of stereotactic radiosurgery (SRS) for recurrent glioblastoma (rGBM) remains uncertain. SRS has been associated with a high risk of radionecrosis in gliomas. ⋯ A single dose of bevacizumab prior to SRS permitted safe prescription dose escalation up to 22 Gy for rGBM. Further evaluation of the efficacy of SRS for rGBM should be performed in the setting of bevacizumab treatment.

Burnout is a syndrome of emotional exhaustion, depersonalization, and reduced personal accomplishment. Its prevalence among US physicians exceeds 50% and is higher among residents/fellows. This is important to the practice of neurosurgery, as burnout is associated with adverse physical health, increased risk of substance abuse, and increased medical errors. To date, no study has specifically addressed the prevalence of burnout among neurosurgery residents. ⋯ Neurosurgery residents have a significantly lower prevalence of burnout than other residents/fellows and practicing physicians. The underlying causes for these findings were not assessed and are likely multifactorial. Future studies should address possible causes of these findings.

Nelson's syndrome may be a devastating complication for patients with Cushing's disease who underwent a bilateral adrenalectomy. Previous studies have demonstrated that stereotactic radiosurgery (SRS) can be used to treat patients with Nelson's syndrome. ⋯ This retrospective analysis suggests that SRS is an effective means of achieving endocrine remission and tumor control in patients with Nelson's syndrome.

Transcranial Doppler ultrasound is a standard screening tool for vasospasm after subarachnoid hemorrhage. Prevention of vasospasm-induced delayed cerebral ischemia after subarachnoid hemorrhage depends on optimization of cerebral perfusion pressure, which can be challenged by neurogenic stress cardiomyopathy. Intra-aortic balloon pumps have been utilized to augment cerebral perfusion, but they change the transcranial Doppler waveform, altering its interpretability for vasospasm screening. ⋯ Delta velocity, a novel transcranial Doppler flow velocity feature, may reflect vasospasm in patients with subarachnoid hemorrhage and intra-aortic balloon pumps.

Shunt infections remain a significant challenge in pediatric neurosurgery. Numerous surgical checklists have been introduced to reduce infection rates. ⋯ Shunt surgery checklist implementation correlated with lower infection rates that persisted in the 4 years after implementation.
