In patients with residual or recurrent nonfunctioning pituitary adenomas (NFPAs) after transsphenoidal resection, both GammaKnife (GKRS) and CyberKnife (CKRS) stereotactic radiosurgery (SRS) are viable treatment options. ⋯ In patients undergoing single fraction GKRS versus fractionated CKRS for NFPAs, both modalities had similar rates of tumor control, new hypopituitarism, and visual morbidity despite varying indications. This study validates the versatile use of these 2 SRS modalities for patients meeting their relative criteria, especially based on proximity to the optic apparatus and normal pituitary gland.

Conus medullaris teratomas are extremely rare, and the treatment experience has been limited. The purpose of the present study was to evaluate the clinical characteristics, radiological features, surgical outcomes, and prognosis of patients with conus medullaris teratoma. ⋯ Total surgical resection is the optimal treatment strategy for patients with conus medullaris teratoma. Safe maximum tumor removal and residual tumor inactivation using electrocoagulation are recommended when total resection cannot be achieved. Surgery can provide a low recurrence rate and an acceptable low complication rate.

Use of C7 Slope as a Surrogate Marker for T1 Slope: A Radiographic Study in Patients with and without Cervical Deformity.
T1 slope has emerged as an important radiographic parameter in the evaluation and surgical management of adult cervical spinal deformity. Given the high rates of nonvisualization of T1 slope on upright cervical radiographs, however, this study examined the evaluation of C7 slope as a potential surrogate marker. ⋯ Results demonstrated that C7 and T1 were in direct correlation in a variety of different cohorts regardless of deformity status or prior fusion. This study indicates that C7 slope may be reliably used a surrogate marker especially when visualization of T1 slope is not possible.

Coronavirus disease-2019 (COVID-19) is a novel disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) that rapidly spread around the globe. The dramatic increase in the number of cases and deaths have placed tremendous strain on health care systems worldwide. As health care workers and society adjust to focus treatment and prevention of COVID-19, other facets of the health care enterprise are affected, particularly surgical volume and revenue. The purpose of this study was to describe the financial impact of COVID-19 on an academic neurosurgery department. ⋯ COVID-19 had a profound detrimental effect on surgical productivity and revenue generation.

The National Surgical Quality Improvement Program (NSQIP) and National Readmission Database (NRD) are 2 widely used databases that provide valuable information regarding the quality of health care. However, the 2 differ in sampling methodology, which may result in conflicting findings when used for research studies. The objective of this study is to evaluate the differences regarding predictors of 30-day readmissions after anterior cervical discectomy and fusion (ACDF) and posterior lumbar fusion (PLF). ⋯ Two databases differed in terms of significant predictors of 30-day readmissions following ACDF and PLF. This difference may emphasize the differences in the sampling methodology. Further analyses, potentially with an institutional validation, are needed to draw conclusions regarding the accuracy of the 2 databases for predictive analytics.
