RESUMO

BACKGROUND: Trauma to the thoracic, thoracolumbar (TL), and lumbar spine is common and can cause disability and neurological deficits. Using a cohort of patients suffering from thoracic, TL, and lumbar spine trauma in a tertiary hospital in East Africa, the current study sought to: (1) describe demographics and operative treatment patterns, (2) assess neurologic outcomes, and (3) report predictors associated with undergoing surgery, neurologic improvement, and mortality. METHODS: A retrospective cohort study of patient records from September 2016 to December 2020 was conducted at a prominent East Africa referral center. The study collected data on demographics, injury, and operative characteristics. Surgical indications were assessed using the AO (Arbeitsgemeinschaft für Osteosynthesefragen) TL fracture classification system and neurological function. Logistic regression analysis identified predictors for operative treatment, neurologic improvement, and mortality. RESULTS: The study showed that 64.9% of the 257 TL spine trauma patients underwent surgery with a median postadmission day of 17.0. The mortality rate was 1.2%. Road traffic accidents caused 43.6% of the injuries. The most common fracture pattern was AO Type A fractures (78.6%). Laminectomy and posterolateral fusion were performed in 97.6% of the surgical cases. Patients without neurological deficits (OR: 0.27, 95% CI: 0.13-0.54, P < 0.001) and those with longer delays from injury to admission were less likely to have surgery (OR: 0.95, 95% CI: 0.92-0.99, P = 0.007). The neurologic improvement rate was 11.1%. Univariate analysis showed a significant association between surgery and neurologic improvement (OR: 3.83, 95% CI: 1.27-16.61, P < 0.001). However, this finding was lost in multivariate regression. CONCLUSIONS: This study highlights various themes surrounding the management of TL spine trauma in a low-resource environment, including lower surgery rates, delays from admission to surgery, safe surgery with low mortality, and the potential for surgery to lead to neurologic improvement. CLINICAL RELEVANCE: Despite challenges such as surgical delays and limited resources in East Africa, there is potential for surgical intervention to improve neurologic outcomes in thoracic, TL, and lumbar spine trauma patients.

RESUMO

BACKGROUND: In sub-Saharan Africa, the estimated prevalence of scoliosis ranges from 3.3% to 5.5%. The management of these deformities is restricted due to lack of infrastructure and access to deformity spine surgeons. Utilizing surgical camps has been demonstrated to be efficient in transferring skills to low-resource environments; however, this has not been documented concerning deformity surgery. METHODS: We conducted a cross-sectional study. The scoliosis camp was held at a major referral spine center in East Africa. We documented information about the organization of the course. We also collected clinical and demographic patient data. Finally, we assessed the knowledge and confidence among surgeon participants on the management scoliosis. RESULTS: The camp lasted 5 days and consisted of lectures and case discussions, followed by casting and surgical sessions. Five patients were operated during the camp. All the patients in the study were diagnosed with AIS, except one with a congenital deformity. The primary curve in the spine was in the thoracic region for all patients. Six months postoperative Scoliosis Research Society-22R Scoring System (SRS-22R) score ranged from 3.3-4.5/5. 87.5% of the participants found the course content satisfactory. CONCLUSIONS: To the best of our knowledge, this is the first time an African scoliosis camp has been established. The study highlights the difficulty of conducting such a course and illustrates the feasibility of executing these complex surgeries in a resource-limited environment.

RESUMO

BACKGROUND: Spine surgery is a rapidly evolving specialty with a continuous need to learn new skills. In resource-limited settings such as Africa, the need for training is greater. The use of simulation-based training is important in different stages of skill acquisition, especially for high-stake procedures such as spine surgery. Among the available methods of simulation, the use of synthetic models has gained popularity among trainers. METHOD: Twenty participants of a neurosurgery training course, most of whom (65%) were neurosurgery residents and fellows, were recruited. They had hands-on training sessions using a high-fidelity lumbar degenerative spine simulation model and hands-on theater experience. After this, they completed a survey to compare their experience and assess the effectiveness of the lumbar spine model in stimulating real patient and surgery experiences. RESULTS: The participants were from four African countries, and the majority were neurosurgery residents. There were varying levels of experience among the participants in minimally invasive spine surgery, with the majority either having no experience or having only observed the procedure. All the participants said that the high-fidelity lumbar spine model effectively simulated real minimally invasive spine setup and real bone haptics and was effective in learning new techniques. Most of the participants agreed that the model effectively simulated real dura and nerve roots (95%), real muscle (90%), real bleeding from bones and muscles (95%), and real cerbrospinal fluid in the subarachnoid space. Among them, 95% agreed that the model is effective in lumbar minimally invasive spine training in resource-limited settings. CONCLUSION: With the development of new and better surgical techniques, the use of high-fidelity models provides a good opportunity for learning and training, especially in resource-poor settings where there is a paucity of training facilities and personnel.

RESUMO

Introduction: The Muhimbili Orthopaedic Institute in collaboration with Weill Cornell Medicine organises an annual neurosurgery training course in Dar es Salaam, Tanzania. The course teaches theory and practical skills in neurotrauma, neurosurgery, and neurointensive care to attendees from across Tanzania and East Africa. This is the only neurosurgical course in Tanzania, where there are few neurosurgeons and limited access to neurosurgical care and equipment. Research question: To investigate the change in self-reported knowledge and confidence in neurosurgical topics amongst the 2022 course attendees. Material and methods: Course participants completed pre and post course questionnaires about their background and self-rated their knowledge and confidence in neurosurgical topics on a five point scale from one (poor) to five (excellent). Responses after the course were compared with those before the course. Results: Four hundred and seventy participants registered for the course, of whom 395(84%) practiced in Tanzania. Experience ranged from students and newly qualified professionals to nurses with more than 10 years of experience and specialist doctors. Both doctors and nurses reported improved knowledge and confidence across all neurosurgical topics following the course. Topics with lower self-ratings prior to the course showed greater improvement. These included neurovascular, neuro-oncology, and minimally invasive spine surgery topics. Suggestions for improvement were mostly related to logistics and course delivery rather than content. Discussion and conclusion: The course reached a wide range of health care professionals in the region and improved neurosurgical knowledge, which should benefit patient care in this underserved region.

RESUMO

BACKGROUND: In nations where tree harvesting constitutes a significant aspect of the economy, such as Tanzania, falls from trees represent a prevalent cause of traumatic injuries. This study investigates the characteristics of traumatic spinal injuries (TSIs) resulting from falls from coconut trees. (CTFs). METHODS: This was a retrospective study of a prospectively maintained spine trauma database at Muhimbili Orthopedic Institute (MOI). We included patients older than 14 years, admitted for TSI secondary to CTF, and with a traumatism not more than 2 months before the admission. Our study analyzed patient data from January 2017 to December 2021. We compiled demographic and clinical information and details such as the distance from the site of trauma to the hospital, American Spinal Injury Association Impairment (ASIA) scale assessment, time to surgery, AOSpine classification, and discharge status. Descriptive analysis was done using data management software. No statistical computing was done. RESULTS: We included 44 patients, all of whom were male, with a mean age of 34.3 ± 12.1 years. At admission, 47.7% of the patients had an ASIA A injury, with the lumbar spine being the most commonly fractured level at 40.9%. In contrast, only 13.6% of the cases involved the cervical spine. Most (65.9%) of the fractures were classified as type A compression fractures (AO classification). Nearly all patients admitted (95.5%) had surgical indications, but only 52.4% received surgical treatment. The overall mortality rate was 4.5%. With respect to neurologic improvement, only 11.4% experienced an improvement in their ASIA score at discharge, the majority of who were in the surgical group. CONCLUSIONS: The present study demonstrates that CTFs in Tanzania constitute a substantial source of TSIs, frequently resulting in severe lumbar injuries. These findings underscore the need for the implementation of educational and preventive measures.

RESUMO

BACKGROUND: Awake craniotomy (AC) is a common neurosurgical procedure for the resection of lesions in eloquent brain areas, which has the advantage of avoiding general anesthesia to reduce associated complications and costs. A significant resource limitation in low- and middle-income countries constrains the usage of AC. OBJECTIVE: To review the published literature on AC in African countries, identify challenges, and propose pragmatic solutions by practicing neurosurgeons in Africa. METHODS: We conducted a scoping review under Preferred Reporting Items for Systematic Reviews and Meta-Analysis-Scoping Review guidelines across 3 databases (PubMed, Scopus, and Web of Science). English articles investigating AC in Africa were included. RESULTS: Nineteen studies consisting of 396 patients were included. Egypt was the most represented country with 8 studies (42.1%), followed by Nigeria with 6 records (31.6%). Glioma was the most common lesion type, corresponding to 120 of 396 patients (30.3%), followed by epilepsy in 71 patients (17.9%). Awake-awake-awake was the most common protocol used in 7 studies (36.8%). Sixteen studies (84.2%) contained adult patients. The youngest reported AC patient was 11 years old, whereas the oldest one was 92. Nine studies (47.4%) reported infrastructure limitations for performing AC, including the lack of funding, intraoperative monitoring equipment, imaging, medications, and limited human resources. CONCLUSION: Despite many constraints, AC is being safely performed in low-resource settings. International collaborations among centers are a move forward, but adequate resources and management are essential to make AC an accessible procedure in many more African neurosurgical centers.

RESUMO

Background The outbreak of COVID-19 caused a significant impact on neurosurgical case volume in Nigeria due to the widespread recommendation to minimize elective procedures and redistribute healthcare resources to support COVID-19 patients. This study aims to analyze the effect of COVID-19 in one tertiary care Nigerian hospital on the demographic characteristics, diagnostic classes, and elective/non-elective procedure statuses. Methods A retrospective single-center chart review study was conducted to review all patients undergoing a neurosurgical procedure between March to June in 2019 and 2020. Descriptive data on patient age, gender, sex, diagnosis, surgical procedure, elective/non-elective surgery status, and month and year of admission were recorded. Diagnoses were categorized into one of seven types by author review. Pearson's Chi-Square and Fisher's Exact Tests were utilized to test for independence of the categorical variables to the year of patient admission, and a Welch two-sample t-test was used to test for a significant difference in mean age between the two cohorts. Results A total of 143 cases were reviewed. There was a 59.8% reduction in overall neurosurgical case volume with an 82% reduction in elective procedures (39 vs. 7, p = 0.017, 95% CI: 1.15 - 8.77) between 2019 and 2020. No significant differences were noted in patient cohorts when comparing demographic characteristics, diagnosis type, or month of admission between the two years. Conclusion There was a significant reduction in elective neurosurgical procedures during the early months of COVID-19 in Nigeria. Further studies should consider examining the effects of COVID-19 into 2021.

RESUMO

BACKGROUND: A significant proportion of the public rely on the internet for their health information, and social media has emerged as the principal information source. YouTube is the world's largest and most popular video library, and it has emerged as a primary health information source because it offers animated and interactive content. However, little is known of its usefulness of neurosurgery videos to African YouTube users. We aim with this study to evaluate the usefulness of YouTube as a source of patient information for neurosurgical care in Africa. METHODOLOGY: This observational study will be conducted using YouTube. A search will be carried out to identify neurosurgery videos suggested to African YouTube viewers from inception to September 2021. An internet browser (Google Chrome, Google Inc., CA, USA) with its cache cleared will be used to execute the search. The default YouTube search setting of "relevance" will be used to replicate what a search attempt performed by a patient would be. The first 50 results from each keyword search will be registered in a Microsoft Excel spreadsheet (Microsoft, WA, USA). The primary outcome measure is the reliability of the videos. Data will be analyzed using SPSS version 26 (IBM, WA, USA). Odds ratios and their 95% confidence intervals will be calculated. The statistically significant level will be set at 0.05. Also, a linear regression analysis will be performed to examine the effects of independent variables on continuous dependent variables. DISSEMINATION: The study findings will be published in an academic peer-reviewed journal, and the abstract will be presented at an international conference. English and French visual and video abstracts of the methods and key findings will be designed and disseminated widely on social media. HIGHLIGHTS: A significant proportion of the public rely on the internet and social media for health information.YouTube has emerged as the world's largest video library, and has emerged as a primary health information source.There are few safeguards to avoid dissemination of false or biased information on the platform this could negatively influence health seeking behaviorWe aim to evaluate the usefulness of YouTube as a source of patient information for neurosurgical care in Africa.The findings of this study will help evaluate the volume and quantity of African neurosurgical video content and identify best practices.

RESUMO

BACKGROUND: Barriers to care cause delays in seeking, reaching, and getting care. These delays affect low-and middle-income countries (LMICs), where 9 out of 10 LMIC inhabitants have no access to basic surgical care. Knowledge of healthcare utilization behavior within underserved communities is useful when developing and implementing health policies. Little is known about the neurosurgical health-seeking behavior of African adults. This study evaluates public awareness, knowledge of availability, and readiness for neurosurgical care services amongst African adults. METHODOLOGY: The cross-sectional study will be run using a self-administered e-survey hosted on Google Forms (Google, CA, USA) disseminated from 10th May 2021 to 10th June 2021. The Questionnaire would be in two languages, English and French. The survey will contain closed-ended, open-ended, and Likert Scale questions. The structured questionnaire will have four sections with 42 questions; Sociodemographic characteristics, Definition of neurosurgery care, Knowledge of neurosurgical diseases, practice and availability, and Common beliefs about neurosurgical care. All consenting adult Africans will be eligible. A minimum sample size of 424 will be used. Data will be analyzed using SPSS version 26 (IBM, WA, USA). Odds ratios and their 95% confidence intervals, Chi-Square test, and ANOVA will be used to test for associations between independent and dependent variables. A P-value <0.05 will be considered statistically significant. Also, a multinomial regression model will be used. DISSEMINATION: The study findings will be published in an academic peer-reviewed journal, and the abstract will be presented at an international conference. HIGHLIGHTS: The burden of neurosurgical diseases is enormous in low- and middle-income countries, especially in Africa.Unfortunately, most neurosurgical needs in Africa are unmet because of delays in seeking, reaching, and getting care.Most efforts aimed at reducing barriers to care have focused on improving the neurosurgical workforce density and infrastructure. Little or no efforts have been directed towards understanding or reducing the barriers to seeking care.We aimed to understand public awareness, willingness to use, and knowledge of the availability of neurosurgical care in Africa.The study findings can inform effective strategies that promote the utilization of neurosurgical services and patient education in Africa.

RESUMO

BACKGROUND: The aim of this study was to document the initial experience and challenges of cervical decompression in a resource-poor region. METHODS: Forty-three patients with cervical myelopathy who had surgery were included in the study. Details including evaluations pre- and postoperative (at 6 weeks and 6 months) using the Nurick score were recorded prospectively. Details of surgery were also documented. RESULTS: The mean age at surgery was 58.0 years. There were 37 men and 6 women. Surgeries performed were anterior cervical decompression and fusion (51.2%), cervical laminectomy (32.6%), corpectomy and occipitocervical fixation (2.3% each), and decompression with lateral mass fixation (11.6%). Four patients presented within 3 months of onset of symptoms (early), whereas 39 after 3 months (late). The Nurick grade significantly improved in 41 patients (97.6%) following surgery (P < 0.001). The average Nurick preoperative score was 3.2, and postoperative it was 2.12 and 1.14 at 6 weeks and 6 months, respectively. In the early presentation group, scores improved from an average preoperative of 2.5-0.5 at 6 months, whereas in the late presentation group, score improved from an average of 3.3 preoperative to 1.2 at 6 months postoperative. CONCLUSIONS: Despite the challenges of poverty, late presentation, and lack of basic standard instruments and equipment, patients with cervical myelopathy in the resource-poor setting had outcomes similar to other well-established centers after surgical decompression. We infer that challenges in setting up a spine unit in a resource-poor region can be circumvented safely.
