Review Case Reports
Long-Term Outcome of Spinal Extranodal Rosai Dorfman Disease: a Report of Two Cases and Systematic Review.
Rosai-Dorfman disease (RDD) is a rare pathologic entity caused by sinus histiocytosis with massive cervical lymphadenopathy. Isolated spinal involvement is an infrequent presentation of extranodal RDD. The clinical and radiologic appearance of RDD represents a diagnostic challenge. We report 2 patients with paraparesis caused by RDD of the thoracic spine and a PRISMA-style systematic review. ⋯ RDD is a rare occurrence and should be considered in the differential diagnosis of extradural or intradural spinal lesions. Gross total resection is recommended, and long-term clinical follow-up with MRI is advised. Residual or recurrent RDD requires steroids or radiation therapy.

Review Historical Article
The History of Anterior and Lateral Approaches to the Lumbar Spine.
Anterior and lateral approaches to the lumbar spine are commonly used today for a variety of indications. These approaches can ultimately be traced back to early attempts to treat Pott's disease. Evidence of Mycobacterium tuberculosis infection of the spine dates as far back as 2400 BCE, with ancient Egyptian mummies exhibiting lesions consistent with Pott's disease. ⋯ In 1906, Müller reported the first successful anterior approach to the spine in a patient with Pott's disease. Over the next several decades, the efforts of surgeons such as Ito, Capener, Burns, and Mercer would lead to the development of the anterior lumbar interbody fusion. The costotransversectomy later evolved into the lateral rhachotomy and lateral extracavitary approach, which along with advances in the anterior lumbar interbody fusion paved the way for the oblique lumbar interbody fusion and lateral lumbar interbody fusion.

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.

Existing research about surgical start time is equivocal about associations between outcomes and late start times, and there is only one published report investigating start time in spine surgery. Therefore, the objective of this study was to assess associations between surgical start time, length of stay (LOS), and cost in lumbar spine surgery. ⋯ Late surgical start time is associated with longer LOS and higher cost in patients undergoing PLF.
