Posterior fossa ischemic infarction: single-center retrospective review of non-surgical and surgical cases.

Cerebellar ischemic stroke (CIS) is a morbid neurological event, with potentially fatal consequences. There is currently no objective standard of care regarding when surgical procedures are required for this entity. We retrospectively reviewed 763 patients with CIS, 247 patients of which had a stroke larger than 1 cm in greatest dimension on cranial imaging.

Evaluation of factors associated with interhospital transfers to pediatric and adult tertiary level of care: A study of acute neurological disease cases.

Introduction: Patient referrals to tertiary level of care neurological services are often potentially avoidable and result in inferior clinical outcomes. To decrease transfer burden, stakeholders should acquire a comprehensive perception of specialty referral process dynamics. We identified associations between patient sociodemographic data, disease category and hospital characteristics and avoidable transfers, and differentiated factors underscoring informed decision making as essential care management aspects.

Effect of Body Mass Index on Paddle Lead Spinal Cord Stimulator Safety Implantation for Chronic Pain Management.

Objective: Spinal cord stimulators (SCS) represent an effective treatment for patients with chronic pain issues. This study examines extremely obese patients (body mass index [BMI] ≥40) as appropriate surgical candidates for paddle lead SCS trial via partial thoracic laminectomy and whether obesity impacts implantation safety.

Methods: A retrospective review of patients treated with partial thoracic laminectomy and paddle lead SCS trial between October 1, 2016 and September 30, 2019 was performed.

Perioperative prophylaxis for surgical site infections in pediatric spinal surgery: a systematic review and network meta-analysis.

Objective: Postoperative infections in pediatric spinal surgery commonly occur and necessitate reoperation(s). However, pediatric-specific infection prophylaxis guidelines are not available. This network meta-analysis compares perioperative prophylaxis methods including Betadine irrigation, saline irrigation, intrawound vancomycin powder, combination therapy (Betadine, vancomycin, gentamicin, and cefuroxime), Betadine irrigation plus vancomycin powder, and no intervention to determine the most efficacious prevention method.

Educational impact of early COVID-19 operating room restrictions on neurosurgery resident training in the United States: A multicenter study.

Background: The coronavirus (COVID-19) pandemic has caused unprecedented suspensions of neurosurgical elective surgeries, a large proportion of which involve spine procedures. The goal of this study is to report granular data on the impact of early COVID-19 pandemic operating room restrictions upon neurosurgical case volume in academic institutions, with attention to its secondary impact upon neurosurgery resident training. This is the first multicenter quantitative study examining these early effects upon neurosurgery residents caseloads.

High-resistance proximal "scaled" ventricular catheters.

Purpose: Prove the concept of high-resistance proximal catheters for valve-independent treatment of hydrocephalus.

Methods: A preliminary design process yielded optimal high-resistance proximal ventricular catheters with a "scaled" design and parallel-oriented, U-shaped inlets. Prototypes were manually constructed using carving tools to stamp through silicone tubings.
