Sir William Macewen (1848-1924): Pioneering the Field of Neurosurgery with Early Breakthroughs in Tumour Resection.
Sir William Macewen, a Scottish surgeon, made significant contributions to neurosurgery, beginning with his successful brain tumor resection in 1879. Born in 1848, Macewen's upbringing in a maritime family fostered a practical approach to learning. Macewen's pivotal brain tumor surgery demonstrated his adherence to antiseptic practices and precise localization techniques. ⋯ Beyond neurosurgery, Macewen was innovative in asepsis, hernia repair, and bone surgery. His legacy as a clinical educator and advocate for surgical advancements earned him widespread recognition. This historical review aimed to explore and evaluate the published literature regarding Macewen's early brain tumor surgeries, seeking to establish his precedence over later surgeons including Godlee and Bennett.

Idiopathic normal pressure hydrocephalus, secondary chronic hydrocephalus, and other cerebrospinal fluid (CSF) disorders are often challenging to diagnose. Since shunt surgery is usually the only therapeutic option and carries significant morbidity, optimal patient selection is crucial. The tap test is the most commonly used prognostic test to confirm the diagnosis but lacks sensitivity. ⋯ We also discuss technical modalities and variations, including one versus 2 needles, patient positioning, and the site of CSF measurement, as well as in vivo shunt testing. Finally, we discuss the limitations and morbidity associated with the LIS. This review aims to assist teams wishing to incorporate LIS into their screening tools for chronic hydrocephalus and other CSF disorders.

Making neurosurgical care accessible to a larger portion of the population in low- and middle-income countries (LMICs) is integral due to the high mortality and morbidity associated with brain tumors. However, the high cost of care often makes it financially out of reach for many individuals. Therefore, this review aims to identify barriers to neurosurgical care of brain tumors in terms of financing in LMICs. ⋯ This study explored barriers and challenges to financing neurosurgical care of brain tumors in LMICs. Government support and transparency in healthcare financing should be prioritized to ensure that all individuals have access to surgical care of brain tumors.

Brain-computer interfaces (BCIs), a remarkable technological advancement in neurology and neurosurgery, mark a significant leap since the inception of electroencephalography in 1924. These interfaces effectively convert central nervous system signals into commands for external devices, offering revolutionary benefits to patients with severe communication and motor impairments due to a myriad of neurological conditions like stroke, spinal cord injuries, and neurodegenerative disorders. BCIs enable these individuals to communicate and interact with their environment, using their brain signals to operate interfaces for communication and environmental control. ⋯ However, challenges persist, including the complexity of accurately interpreting brain signals, the need for individual calibration, and ensuring reliable, long-term use. Additionally, ethical considerations arise regarding autonomy, consent, and the potential for dependence on technology. Despite these challenges, BCIs represent a transformative development in neurotechnology, promising enhanced patient outcomes and a deeper understanding of brain-machine interfaces.

Urgent Call for International Support and Research Focus on Neurosurgery in Conflict-Affected Sudan.
Neurosurgical services and educational processes in Sudan have been severely disrupted by the ongoing armed conflict. The destruction of neurosurgical infrastructure and the continuous exodus of trained neurosurgeons from an already strained system have intensified the humanitarian crisis. ⋯ The re-establishment of international partnerships and the reconstruction of damaged neurosurgical infrastructure are advocated, coupled with the utilization of advanced research to address these critical issues. A staged recovery strategy is called for, and support from the global neurosurgical community is urged, highlighting the crucial role of academic platforms like "World Neurosurgery" in fostering global collaboration and disseminating research from conflict-affected regions.
