Presentation, management, and outcomes of pediatric hydrocephalus in Africa: a systematic review and meta-analysis of 12,355 patients.

OBJECTIVE: The prevalence, management, and outcomes of hydrocephalus remain underexplored in Africa. This study aimed to analyze demographic and clinical features, evaluate treatment strategies, and assess neurological outcomes of pediatric hydrocephalus in Africa. METHODS: A systematic review of the literature using the PubMed, Google Scholar, and Web of Science electronic databases was completed according to the PRISMA guidelines to identify articles describing pediatric patients in Africa with hydrocephalus. RESULTS: Seventy-four retrospective and prospective studies and 33 case reports involving 12,355 patients were included. In 54 retrospective articles reporting patient demographics, 53.8% (3926/7297) were male with a mean age of 12.3 months. Nineteen studies reported macrocephaly (80.2%, 1639/2043) as the most common presentation. The etiology of hydrocephalus was reported as postinfectious (41.0%, 2303/5614) across 27 articles and congenital (48.6%, 1246/2563) in 10 articles. Eleven articles reported 46.7% (609/1305) of patients had communicating hydrocephalus while 53.3% (696/1305) had obstructive hydrocephalus. Diagnostic imaging included CT (76.1%, 2435/3202; n = 29 articles), ultrasonography (72.9%, 2043/2801; n = 15 articles), and MRI (44.8%, 549/1225; n = 11 articles). In 51 articles, 83.1% (7365/8865) of patients had ventriculoperitoneal shunting (VPS) while 33 articles described 54.1% (2795/5169) receiving endoscopic third ventriculostomy (ETV) for hydrocephalus surgical management. Postoperative complications included sepsis (6.9%, 29/421; n = 4 articles), surgical site infections (5.1%, 11/218; n = 4 articles), and CSF leaks (2.0%, 15/748; n = 8 articles). Shunt-related complications included infections (4.3%, 117/2717; n = 21 articles) and blockages (4.1%, 34/829; n = 6 studies). In 15 articles, 9.0% (301/3358) of patients with shunts had revisions. The mean follow-up duration was 18.9 ± 16.7 months with an overall mortality rate of 7.4% (397/5383; n = 29 articles). In the analysis of comparative studies, the 160 patients undergoing ETV demonstrated significantly higher odds of a successful operation (OR 1.54, 95% CI 0.51-4.69; p = 0.03) and neurological improvement at last follow-up (OR 3.36, 95% CI 0.46-24.79; p < 0.01) compared with the 158 who received VPS, but no significant differences were observed for complications and mortality between the two groups (p > 0.05). CONCLUSIONS: This review offers a comprehensive summary of pediatric hydrocephalus in Africa, highlighting shunting as the primary treatment. However, the observed variations across studies highlight the need to establish standardized guidelines for reporting patient characteristics, management strategies, and outcomes to ensure consistency and comparability in articles.

Ethics of deep brain stimulation for neuropsychiatric disorders.

Deep Brain Stimulation (DBS) has emerged as a revolutionary neurosurgical technique with significant implications for the treatment of various neuropsychiatric disorders. Initially developed for movement disorders like Parkinson's disease, DBS has expanded to psychiatric conditions such as obsessive-compulsive disorder, depression, anorexia nervosa, dystonia, essential tremor, and Tourette's syndrome. This paper explores the clinical efficacy and ethical considerations of DBS in treating these disorders. While DBS has shown substantial promise in alleviating symptoms and improving quality of life, it raises ethical challenges, including issues of informed consent, patient selection, long-term management, and equitable access to treatment. The irreversible nature of DBS, potential adverse effects, and the high cost of the procedure necessitate a rigorous ethical framework to guide its application. The ongoing evolution of neuromodulation requires continuous ethical analysis and the development of guidelines to ensure that DBS is used responsibly and equitably across different patient populations. This paper underscores the need for a balanced approach that integrates clinical efficacy with ethical considerations to optimize patient outcomes and ensure sustainable practice.

Neuro-oncology access in Sub-Saharan Africa: A literature review of challenges and opportunities.

Background: Ensuring equitable access to treatments and therapies in the constantly evolving field of neuro-oncology is an imperative global health issue. With its unique demographic, cultural, socioeconomic, and infrastructure characteristics, Sub-Saharan Africa faces distinct challenges. This literature review highlights specific barriers to neuro-oncology care in the region and explores potential opportunities for enhancing access. Methods: Predetermined keyword searches were employed to screen titles and abstracts using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework. Inclusion criteria were studies published between January 1, 2003, and June 20, 2023, specifically addressing the capacity and challenges of neuro-oncology in the Sub-Saharan African region. The data sources queried were PubMed and Google Scholar. Systematic reviews and meta-analyses were deliberately excluded. All authors conducted independent screening and structured data extraction meticulously. Results: Our paper identified multiple challenges that impede access to quality treatment for brain tumors. These include constrained resources, insufficient training of healthcare professionals, certain cultural beliefs, and a general lack of awareness about brain tumors, all contributing to delayed diagnosis and treatment. Furthermore, the lack of detailed data on the incidence and prevalence of primary central nervous system tumors impairs the accurate assessment of disease burden and precise identification of areas requiring improvement. However, we discovered that ongoing research, advocacy, enhanced training, mentorship, and collaborative efforts present valuable opportunities for substantial progress in neuro-oncology access. Conclusions: While we provide a glimpse of the current state, we hope these results will help stimulate dialogue and catalyze initiatives to surmount highlighted obstacles and improve neuro-oncology outcomes across Sub-Saharan Africa.

Bridging Minds and Machines: The Recent Advances of Brain-Computer Interfaces in Neurological and Neurosurgical Applications.

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. This technology is especially crucial for those completely locked in, providing a communication lifeline where other methods fall short. The advantages of BCIs are profound, offering autonomy and an improved quality of life for patients with severe disabilities. They allow for direct interaction with various devices and prostheses, bypassing damaged or nonfunctional neural pathways. 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.
