The Landscape of Neurosurgical Oncology Adjunct Usage in Africa: A Scoping Review.

BACKGROUND: Intraoperative neurosurgical adjuncts improve extent of resection whilst mitigating patient morbidity. The delivery of neurosurgical care via these adjuncts is the norm in high-income countries, but there is yet to be a study highlighting the usage of neurosurgical oncology adjuncts in Africa. This paper aims to provide awareness of the use of these adjuncts in Africa, reasons for limited procurement, and possible solutions to the problem. METHODS: This scoping review was conducted in accordance with Preferred Reporting Items for Systematic Review and Meta-Analysis Extension for Scoping Reviews guidelines. Semantic derivatives of neurosurgical oncology, adjuncts, and Africa were applied to medical databases. Studies in Africa with outcomes relating to adjunct usage, morbidity, mortality, and quality of life were selected. Book chapters and reviews were excluded. RESULTS: Thirteen studies with 287 patients (0.5 to 74 years) were included in the final analysis. Most studies were cohort observational (46.2%) and originated from South Africa (46.2%). Meningioma was the most prevalent tumor histology (39.4%), and neuronavigation was the most readily used adjunct for surgical resection (30.8%). Using adjuncts, gross total resection was achieved in close to half the patient cohort (49.8%). Limited technology, lack of experience, cost of equipment, and inconsistency in power supply were noted as factors contributing to lack of adjunct usage. CONCLUSIONS: Neurosurgical adjuncts provide significant benefits in neurosurgical oncology. There is limited utilization of intraoperative adjuncts in most of Africa owing to limited resources and experienced professionals. Bilateral partnerships with a focus on donation and education will foster safe and sustainable adjunct incorporation in Africa.

The World Neurosurgery Global Champions Program: First-Year Experience of a Model Initiative for Reducing Disparities in Global Neurosurgical Literature.

OBJECTIVE: Most surgical journals are published in English, representing a challenge for researchers from non-Anglophone countries. We describe the implementation, workflow, outcomes, and lessons learned from the WORLD NEUROSURGERY Global Champions Program (GCP), a novel journal-specific English language editing program for articles rejected because of poor English grammar or usage. METHODS: The GCP was advertised via the journal website and social media. Applicants were selected to be a reviewer for the GCP if they demonstrated English proficiency on writing samples supplied in their application. The demographics of GCP members and characteristics and outcomes of articles edited by the GCP during its first year were reviewed. Surveys of GCP members and authors who used the service were conducted. RESULTS: Twenty-one individuals became part of the GCP, representing 8 countries and 16 languages apart from English. A total of 380 manuscripts were peer reviewed by the editor-in-chief, who determined these manuscripts to have potentially worthwhile content but needed to be rejected due to poor language. The authors of these manuscripts were informed of the existence of this language assistance program. Forty-nine articles (12.9%) were edited by the GCP in 41.6 ± 22.8 days. Of 40 articles resubmitted to WORLD NEUROSURGERY, 24 (60.0%) were accepted. GCP members and authors understood the purpose and workflow of the program and recognized improvements in article quality and the probability of acceptance through their participation. CONCLUSIONS: The WORLD NEUROSURGERY Global Champions Program mitigated a critical barrier to publication in an English language journal for authors from non-Anglophone countries. This program promotes research equity by providing a free, largely medical student and trainee operated, English language editing service. This model or a similar service can be replicated by other journals.

Determining the Minimum Dataset for Surgical Patients in Africa: A Delphi Study.

BACKGROUND: It is often difficult for clinicians in African low- and middle-income countries middle-income countries to access useful aggregated data to identify areas for quality improvement. The aim of this Delphi study was to develop a standardised perioperative dataset for use in a registry. METHODS: A Delphi method was followed to achieve consensus on the data points to include in a minimum perioperative dataset. The study consisted of two electronic surveys, followed by an online discussion and a final electronic survey (four Rounds). RESULTS: Forty-one members of the African Perioperative Research Group participated in the process. Forty data points were deemed important and feasible to include in a minimum dataset for electronic capturing during the perioperative workflow by clinicians. A smaller dataset consisting of eight variables to define risk-adjusted perioperative mortality rate was also described. CONCLUSIONS: The minimum perioperative dataset can be used in a collaborative effort to establish a resource accessible to African clinicians in improving quality of care.

Access to training in neurosurgery (Part 1): Global perspectives and contributing factors of barriers to access.

Introduction: Neurological disorders are one of the leading causes of death and disability adjusted life years (DALYs). Efforts have been made to increase the neurosurgical workforce in an attempt to address the global disease burden. Despite these efforts, there continues to be a shortage of neurosurgeons in both high-income countries (HICs) and low-and middle-income countries (LMICs). Research question: The aim of the study was to identify the barriers to neurosurgical training in LMICs and HICs. Materials and methods: We administered an electronic survey targeting medical students, neurosurgery residents, and recent neurosurgery graduates from 69 countries in both HICs and LMICs. Questions were framed to assess barriers to training. Results: Of the 198 responses received (31.3% response rate), 72% identified as male, 27% female, and 0.5% as non-binary gender. 33 respondents were from HICs and 165 were from LMICs. 70.1% of respondents reported no availability of dissection labs in their home institutions. There was a significant difference in availability of subspecialty training between LMICs and HMICs (p â€‹= â€‹0.001) but no significance was seen for competitiveness of programs (p â€‹= â€‹0.473). Discussion and conclusion: There are limitations to our study: it is not comprehensive of training programs globally, there is sampling bias, especially among LMICs, and the accuracy of responses is unclear. Nonetheless, our results highlight the need for a deliberate focus on designing and implementing both short and long term goals in tackling barriers to access to neurosurgical training, with a conscientious effort to involve interested stakeholders and governments to invest in the training and education of their neurosurgical workforce.

Access to training in neurosurgery (Part 2): The costs of pursuing neurosurgical training.

Introduction: Opportunities for in-country neurosurgical training are severely limited in LMICs, particularly due to rigorous educational requirements and prohibitive upfront costs. Research question: This study aims to evaluate financial barriers aspiring neurosurgeons face in accessing and completing neurosurgical training, specifically in LMICs, in order to determine the barriers to equitable access to training. Material and methods: In order to assess the financial costs of accessing and completing neurosurgery residency, an electronic survey was administered to those with the most recent experience with the process: aspiring neurosurgeons, neurosurgical trainees, and recent neurosurgery graduates. We attempted to include a broad representation of World Health Organization (WHO) geographic regions and World Bank income classifications in order to determine differences among regions and countries of different income levels. Results: Our survey resulted in 198 unique responses (response rate 31.3%), of which 83% (n â€‹= â€‹165) were from LMICs. Cost data were reported for 48 individual countries, of which 26.2% were reported to require trainees to pay for their neurosurgical training. Payment amounts varied amongst countries, with multiple countries having costs that surpassed their annual gross national income as defined by the World Bank. Discussion and conclusions: Opportunities for formal neurosurgical training are severely limited, especially in LMICs. Cost is an important barrier that can not only limit the capacity to train neurosurgeons but can also perpetuate inequitable access to training. Additional investment by governments and other stakeholders can help develop a sufficient workforce and reduce inequality for the next generation of neurosurgeons worldwide.

Moyamoya syndrome and stroke among pediatric sickle cell disease patients in Sudan: A cross-sectional study.

Background: Sickle cell disease (SCD) is autosomal recessive hemolytic anemia due to hemoglobinopathy commonly in Sub-Saharan Africa, and particularly in Sudan. The disease induces a pro-inflammatory cascade in the intimal layer that leads to hyperplasia and progressive stenosis in the major vessel of the circle of Willis. This is associated with the development of Moyamoya collaterals. The aim of this study is to highlight the frequency of Moyamoya syndrome in Sudanese pediatric patients with sickle cell disease presenting with stroke. Materials and methods: A descriptive cross-sectional hospital-based study was conducted in the Department of Hematology at Gaafar Ibnauf Pediatric Tertiary Hospital in Khartoum state in Sudan, in the period between March 2021 and August 2021. Secondary data has been collected from the medical record after ethical approval and informed consent. Results: A total of 104 patients were included in the study. The males were the majority, about 60 (57.7) compared to 44 (42.3%) females. More than half of our study population was in the school-age 54 compared to 42 adolescents and only 8 patients of preschool age. Only 50 out of 104 patients had diagnostic MRA which revealed features of Moyamoya syndrome in 48 (96%) patients. Motor weakness (100%), aphasia (52.9%), and facial palsy (35%) were the major stroke presentations. The left anterior circulation territory was the most common site of moyamoya features involvement in 31 patients out of 48. Conclusion: Stroke is a common problem in Sudanese pediatric patients with sickle cell disease, with a very high frequency of Moyamoya vasculopathy among patients with stroke presentation. The burden of Moyamoya syndrome in Sudanese pediatric patients with sickle cell disease is underestimated due to the cost of the available screening and diagnostic tools.

Orbital Actinomycetoma with cranial extension: A rare case report.

INTRODUCTION: Mycetoma is a neglected tropical disease that commonly affects the lower extremity. The disease is attributed to subcutaneous granulomatous inflammation leading to distinct clinical features of gradual painless swelling accompanied by nodules and drains. Orbital mycetoma is an extremely rare entity of the disease. We reported the clinical presentation, diagnosis, and surgical outcomes in a case of orbital mycetoma with cranial extension. CASE PRESENTATION: A 25-years-old male complained of left eye protrusion for 8 years, followed by complete loss of vision on the left eye for 7 years and eventually left eye pain for the last year. The left eye was displaced anteriorly and inferiorly with normal oculomotor, abducent, and trochlear examination. Brain CT scan showed an increase in orbital bone thickness with extension to the anterior cranial base, middle cranial base, and the orbital process of the zygomatic bone. MRI revealed a large lesion involving the left frontotemporal region with extension to left orbit, left posterior ethmoid air cells, and left temporal suprasellar region. The lesion was homogenously enhanced with contrast. The patient underwent a left orbitozygomatic cranitomy for resection of the lesion. However, total resection was inapplicable due to the extension of the bony lesion up to the petrous bone. Cranioplasty was performed by titanium mesh. CONCLUSION: Mycetoma is a chronic inflammatory disease affecting subcutaneous tissues commonly in the lower limbs. The disease can be caused by fungi (Eumycetoma) or bacteria (Actinomycetoma). Orbital mycetoma is an extremely rare entity of the disease. However, it is commonly associated with the cranial extension. Early diagnosis and prompt surgical and medical treatment are the keys to good outcomes.

Post-traumatic bilateral synchronous acute extradural hematomas: A case report and review of literature.

INTRODUCTION: and importance:Bilateral extradural hematomas account for less than 5% of all entities of extradural hematomas. The condition is generally caused by traumatic brain injury, which can form separate hematomas contralaterally or joint bilateral extradural hematomas commonly owing to superior sagittal sinus injury. In light of the above, this is the first case of such a condition to be reported from Sudan in the literature. CASE PRESENTATION: A 31-years-old male presented with headache, confusion, and 4 episodes of non-projectile vomiting with a GCS score of 14, after being assaulted by direct blunt head trauma. CT brain showed acute extradural hematoma on the right frontotemporal part compared to a parietal extradural hematoma on the contralateral side. The patient underwent bilateral craniotomy with a wide question mark-like skin flap on the right temporoparietal side followed by 5 burr holes. On the left side, parietal craniotomy was made with an inverted U-shaped skin flap and 4 burr holes on the left parietal side, after that two surgical drains were inserted bilaterally. The patient was discharged on the third postoperative day with a GCS of 15. DISCUSSION: Although bilateral extradural hematomas are rare and grave conditions, prompt surgical intervention has shown low morbidity and mortality rate with markedly favorable postoperative outcomes. CONCLUSION: Bilateral extradural hematomas can be attributed to extended linear fracture caused by superior sagittal sinus injury. CT scan is the gold standard imaging. However, MRI and MRV can be used to demonstrate injury or occlusion of the Superior sagittal sinus.
