Understanding Adult Central Nervous System Hemangioblastomas: meta-analysis of meta-analysis.
Adult hemangioblastomas (HBs) are rare World Health Organization central nervous system (CNS) grade 1 tumors, particularly affecting the posterior cranial fossa. They exhibit a gender bias, impacting men in their fifth and sixth decades of life and manifesting sporadically or as part of von Hippel Lindau disease. Understanding the intricacies of CNS HBs is crucial for clinical decision-making. ⋯ Adult CNS HBs present with diverse characteristics and clinical manifestations. Surgical intervention remains the mainstay treatment; ongoing research into genetic and molecular mechanisms may enhance our understanding of tumor pathology and lead to improved management strategies in the future.

Stem Cells in the Treatment of Spinal Cord Injury: A Review of Currently Registered Clinical Trials.
Spinal cord injury (SCI) affects around 18,000 individuals annually, representing nearly one-third of all paralysis cases. Stem cell therapy, a focal point in contemporary neuroregeneration research for SCI treatment, holds potential in leveraging undifferentiated stem cells to regenerate damaged tissues. This study seeks to comprehensively analyze current clinical trials exploring the potential use of stem cells in treating spinal cord injuries. ⋯ The promising potential of stem cells in neuroregenerative SCI treatment necessitates further exploration through large-scale, multicenter clinical trials to enhance understanding and guide wider adoption of this emerging treatment paradigm.

Evolution of Neurosurgical Robots: Historical Progress and Future Direction.
In 1985, Professor KWOH first introduced robots into neurosurgery. Since then, advancements of stereotactic frames, radiographic imaging, and neuronavigation have led to the dominance of classic stereotactic robots. A comprehensive retrieval was performed using academic databases and search agents to acquire professional information, with a cutoff date of June, 2024. ⋯ Those technologies have been applied in innovative magnetic resonance-compatible neurosurgical robots, such as Neuroarm and Neurobot, with real-time image-guided surgery. Despite these advancements, the major challenge is considered as magnetic resonance compatibility in terms of space, materials, driving, and imaging. Future research directions are anticipated to focus on 1) robotic precise perception; 2) artificial intelligence; and 3) the advancement of telesurgery.

The primary treatment for peripheral nerve tumors involves maximal surgical resection while preserving nerve function. Sodium fluorescein shows potential for enhancing the safety and efficacy of nerve tumor surgery. This review evaluates the advantages and limitations of sodium fluorescein in this context. ⋯ Sodium fluorescein shows promise as assisting tool in nerve tumor surgery by facilitating differentiation among the tumor, parent nerve, and surrounding soft tissue. However, multicenter randomized controlled trials are necessary to determine its effect on extent of resection rates, clinical outcomes, postoperative complication rates, and surgical duration in comparison to current standard of care.

This review aims to comprehensively summarize the application of electrophysiological methods, specifically repetitive nerve stimulation (RNS) and single fiber electromyography (SFEMG), in the diagnosis of neuromuscular junction (NMJ) disorders, including myasthenia gravis, Lambert-Eaton syndrome, and sarcopenia in the elderly. Both RNS and SFEMG have demonstrated high sensitivity and specificity in detecting NMJ abnormalities. ⋯ Increased fiber density and jitter value, along with pulse blocking, are often observed in patients with NMJ disorders. However, despite the extensive application of these techniques in various NMJ-related diseases, their role in aging, particularly in sarcopenic patients, remains underexplored, highlighting the need for future research.
