Awake craniotomies in South America: Advancements, challenges, and future prospects.

BACKGROUND: Awake craniotomy has emerged as an advanced surgical technique, characterized by keeping the patient awake during brain surgery. In South America, awake craniotomies have grained traction in neurosurgical practices across various medical centres and hospitals, with notable practitioners contributing to its growth and refinement in the region. PURPOSE: This study aims to explore the integration and impact of awake craniotomies in South American neurosurgical practices. The focus is on understanding the benefits, challenges, and potential transformative effects of the procedure in the region. RESEARCH DESIGN: A comprehensive narrative review and analysis through a thorough examination of the existing literature. RESULTS: The findings indicate that awake craniotomies in South America offer substantial benefits, including cost savings thorugh reduced hospitalization time, quicker recovery and decreased morbidity. Enhanced safety, effective pain management and reduced anaesthesia also contribute to this. CONCLUSION: Whilst the adaptation of awake craniotomies in South America holds great promise in transforming neurosurgical care in the region, significant challenges hinder its widespread adoption. Inadequate infrastructure, limited access to equipment, financial instability, and shortages in trained healthcare providers represent challenges that need to be addressed.

Challenges and opportunities in prostate cancer surgery in South America: Insights into robot-assisted radical prostatectomies-A perspective.

Background and Aims: Prostate cancer imposes a significant health burden, particularly in South America with its high incidence and mortality rates. This article explores the emergence of robot-assisted radical prostatectomy (RARP) as a potential solution in the region. Methods: This study relies on a comprehensive review of relevant literature. The analysis highlights the advantages of RARP, identifies impediments to its implementation, and proposes strategies to overcome these barriers. Results: RARP demonstrates notable benefits, including improved functional outcomes, reduced complications, and minimized incisions. However, the integration of RARP in South America is hindered by challenges such as regional disparities, financial limitations, and data gaps. Limited healthcare infrastructure and a scarcity of skilled professionals further compound the issues. Conclusion: Despite its potential, RARP faces obstacles to widespread adoption in South America. Strategic solutions encompassing technology investment, healthcare infrastructure enhancement, and workforce training are imperative. Overcoming these challenges can establish RARP as a crucial tool in managing prostate cancer in the region, ultimately enhancing patient care and treatment outcomes.

Microsurgical and endovascular treatment of posterior inferior cerebellar artery aneurysms: a systematic review and meta-analysis.

INTRODUCTION: Posterior inferior cerebellar artery (PICA) aneurysms are uncommon vascular lesions of the posterior fossa. In addition to aneurysmal morphology, structural anatomic considerations may confer additional procedural risk, and as a result there is currently no consensus as to whether a surgical or endovascular approach offers greater safety and efficacy for patients. EVIDENCE ACQUISITION: We systematically examined peer-reviewed literature describing PICA aneurysm treatment planning from January 2000 to May 2021 using the PRISMA methodology. A meta-analysis of proportions was performed. Certainty of the evidence was assessed using the GRADE approach. EVIDENCE SYNTHESIS: Fifty-eight studies including 1673 PICA aneurysms were analyzed. Overall treatment occlusion rate was 97% (95% confidence interval [CI]: 93-100%) for surgery and 85% (95% CI: 78-92%) for endovascular therapy. The recurrence rate was 6% in the endovascular group and 1% for surgery. Overall morbidity and mortality were 16% and 7%, respectively. Intraoperative complications occurred in 9% of the surgical patients. CONCLUSIONS: Despite a large body of literature, analysis indicates that 62% of studies had moderate or serious risk of bias, suggesting very-low certainty results. Therefore, treatment via either approach should be determined on a case-by-case basis and according to institutional experience.

Aceptación de la vacunación contra la COVID-19 durante la primera ola pandémica en Perú / Acceptance of COVID-19 vaccination during the first pandemic wave in Peru

Señor editor: El exceso de muertes debido a la COVID-19 en Perú durante el 2020fueunodelosmáselevadosdelmundo,esto probablemente favorecido por la fragilidad del sistema salud y los determinantes sociales de este país. Si bien una de las principales estrategias para mitigar el impacto de esta enfermedad es la vacunación masiva, la falta de aceptación de la vacuna por parte de la población peruana podría ser uno de los mayores desafíos para lograr dicho objetivo.

Mr. Editor: The excess of deaths due to COVID-19 in Peru during 2020 was one of the highest in the world, probably favored by the fragility of the health system and the social determinants of this country. Although one of the main strategies to mitigate the impact of this disease is mass vaccination, the lack of acceptance of the vaccine by the Peruvian population could be one of the biggest challenges to achieve this goal.
