In a retrospective study, we sought to compare the clinical efficacy and postoperative magnetic resonance imaging (MRI) scans of minimally invasive (MI) and open (O) transforaminal lumbar interbody fusion (TLIF) in the treatment of cauda equina syndrome (CES) caused by lumbar disc herniation. ⋯ In patients with acute CES caused by disc herniation, MI-TLIF, with decreased disruption of paravertebral tissues and postoperative pain syndrome, results in earlier mobilization and rehabilitation with better long-term clinical outcomes compared with O-TLIF.

Observational Study
Role of Nimodipine and Milrinone in Delayed Cerebral Ischemia.
The role of nimodipine and milrinone in the management of delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage (SAH) was studied using clinical and TCD (transcranial Doppler) parameters. ⋯ In this single-center small study, patients in the IAN group had significantly less mortality compared with the IVM group in the management of DCI after aneurysmal SAH.

In the past, low-grade gliomas-World Health Organization (WHO) grade I and II tumors-were generally expected to have a much better prognosis than higher-grade (WHO grade III and IV) gliomas. However, diffuse gliomas (WHO grade II), unlike WHO grade I gliomas, are by definition infiltrative, limiting resection and potentially contributing to poor outcomes like those seen with malignant gliomas. ⋯ These molecular characteristics outweigh the histologic distinctions and have been quickly incorporated into the WHO classification of gliomas. Management of these tumors with surgery, radiation, and chemotherapy has similarly been transformed by these developments, highlighting the need for a customized approach for patients with low-grade gliomas.

Low-grade gliomas are clinically challenging entities. Patients with these tumors tend to be relatively young at presentation, and lesions are often incidental findings or are identified because the patient presents with a seizure. Rapidly emerging and evolving molecular classifications of gliomas have influenced treatment paradigms. ⋯ Literature supports improved overall survival and outcomes with increased extent of resection for low-grade glioma. Awake craniotomies and resection of insular low-grade gliomas both have been demonstrated as safe and improve outcomes for patients with lesions located in eloquent areas. Given the younger age at diagnosis of these lesions compared with higher-grade gliomas, fertility, fertility preservation, and potential malignant transformation should be discussed with patients of childbearing age.

Neurosurgery (NS) is among the most selective specialties in the United States. As the United States Medical Licensing Examination (USMLE) Step 1 transitions to a binary pass/fail score, residency programs face unclear challenges in screening and evaluating applicants. The aim of this study is to provide insights into the perceived impact of changes to the USMLE Step 1 grading in the applicant selection process. ⋯ Reporting binary Step 1 grades marks a significant shift in assessing applicants for NS residency by emphasizing Step 2 CK, class rank, and research productivity.
