Pediatric hydrocephalus is a significant health burden globally, particularly in low- and middle-income countries. Data from specific regions such as KwaZulu-Natal, South Africa, are lacking. This study aimed to investigate pediatric hydrocephalus by comparing 4 distinct 5-year periods. ⋯ This study provides comprehensive insights into pediatric hydrocephalus in KwaZulu-Natal. Monitoring temporal trends and predictors of outcomes will guide future interventions to mitigate the burden of pediatric hydrocephalus in the region.

Observational Study
What is the Value Proposition of Evidence-Based Guidelines? An Application of the Operative Value Index for Lumbar Fusions.
Elective lumbar fusions have received criticism for inappropriate utilization. Here, we use a novel Operative Value Index (OVI) to assess whether "indicated," evidence-based lumbar fusions are associated with increased value (outcomes per dollar spent). ⋯ EBM-concordant fusions were associated with 2% greater improvement in ODI scores from baseline for every $1000 spent intraoperatively. Systematic methods for increasing guideline adherence for lumbar fusions could therefore improve value at scale.

Enhancing Diagnostic Support for Chiari Malformation and Syringomyelia: A Comparative Study of Contextualized ChatGPT Models.
The rapidly increasing adoption of large language models in medicine has drawn attention to potential applications within the field of neurosurgery. This study evaluates the effects of various contextualization methods on ChatGPT's ability to provide expert-consensus aligned recommendations on the diagnosis and management of Chiari Malformation and Syringomyelia. ⋯ The enhanced performance observed in response to ChatGPT4 contextualization suggests broader applications of large language models in neurosurgery than what the current literature indicates. This study provides proof of concept for the use of contextualized GPT models in neurosurgical contexts and showcases the easy accessibility of improved model performance.

We describe our protocol and outcomes of awake robotic minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) under spinal anesthesia. ⋯ Our study showed significant improvement in patient-reported outcomes at 1-month and 1-year follow-ups after awake robotic MIS-TLIF, as well as solid bony fusion on CT scans.

Routine evaluation and surveillance imaging after pituitary adenoma (PA) endoscopic endonasal transsphenoidal resection (EETS) is a neurosurgical practice to identify tumor recurrence. This study aims to identify social and clinical factors that may contribute to patients missing their initial 1-year follow-up appointment and provide guidance for targeted education to improve patient adherence with postoperative treatment plans, ultimately reducing unknown adenoma recurrence. ⋯ Risk factors of missed 1-year follow-up appointments after PA resection include male sex, divorced/widowed/separated marital status, older age, and the presence of visual deficits at initial presentation. Increased education efforts can be selectively aimed at these at-risk patient cohorts to improve patient compliance and reduce consequences of undetected tumor recurrence.
