Spinal cord stimulation (SCS) is a neuromodulation process to treat neuropathic pain, initially developed on tonic paresthesia-based stimulation. In the last decade, 3 major paresthesia-free SCSs have emerged. Several studies show their superiority over tonic stimulation. ⋯ Recent studies show superiority of paresthesia-free SCS compared with tonic SCS and those results are corroborated by analysis of patients' preferences. Taking these data into account should motivate physicians to opt for multimodal capable devices before implanting SCS.

The 2019 novel coronavirus disease (COVID-19) pandemic has directly and indirectly impacted health care systems, including residency programs. Social distancing, cancellation of elective cases, and staff re-deployment have compromised clinical and academic teaching. We describe the neurosurgical experience at Emory University during the COVID-19 pandemic and the impact of COVID-19-related policies on resident experience. ⋯ Even at academic centers that were not hugely impacted by the COVID-19 pandemic, prophylactic and preparedness measures still exhibited an unprecedented toll on neurosurgical resident and fellow experience.

Sellar cholesterol granuloma mimicking cystic sellar lesions: A report of three cases and literature review.
Cystic lesions in the sellar region include a variety of entities, such as craniopharyngioma, Rathke cleft cyst (RCC), intrasellar arachnoid cyst, cystic pituitary adenomas, cholesterol granulomas (CGs), and xanthogranulomas (XGs). The distinction among them remains a preoperative challenge due to similarities in their clinical and radiologic findings. ⋯ CG/XG is an uncommon pathology with unspecific clinical and radiologic features. However, this pathology should be considered in the differential diagnosis of mixed cystic/solid lesions in the sellar region.

Many clinical and demographic factors can influence survival of patients with hematologic malignancies who have intracranial hemorrhages (ICHs). Understanding the influence of these factors on patient survival can guide treatment decisions and may inform prognostic discussions. We conducted a systematic literature review to determine survival of patients with intracranial hemorrhages and concomitant hematologic malignancy. ⋯ Survival for patients with hematologic malignancies and concomitant ICHs remains poor. Early detection, recognition of poor prognostic factors, and correction of hematologic abnormalities essential to prevention and treatment of ICHs in this patient population.

With a growing aging population in the United States, the number of operative lumbar spine pathologies continues to grow. Therefore, our objective was to estimate the future demand for lumbar spine surgery volumes for the United States to the year 2040. ⋯ The large increases in expected volumes of ALIF and PLF could necessitate training of more spinal surgeons and an examination of projected costs. Further analyses are needed to characterize the needs of this increasingly large population of surgical patients.
