Management and outcome of intracranial fungal infections in children and adults in Africa: a scoping review.

INTRODUCTION: Intracranial fungal infections' (IcFIs) varying clinical manifestations lead to difficulties in diagnosis and treatment. African populations are disproportionately affected by the high burden of the disease. There is a lack of clarity as to the diagnostic and treatment modalities employed across the continent. In this review, we aim to detail the management, and outcome of IcFIs across Africa. METHODS: This scoping review was conducted using the Arksey and O'Malley framework. MEDLINE, EMBASE, Cochrane Library, African Index Medicus, and African Journals Online were searched for relevant articles from database inception to August 10th, 2021. The Preferred Reporting Items for Systematic Review and Meta-Analysis extension for Scoping Reviews guidelines were used to report the findings of the review. RESULTS: Of the 5,779 records identified, 131 articles were included. The mean age was 35.6 years, and the majority (56.4%) were males. The majority (n = 8,433/8,693, 97.0%) of IcFIs presented as a meningitis, the most common communicable predisposing factor of IcFIs was HIV/AIDS (n = 7,815/8,693, 89.9%), and the most common non-communicable risk factor was diabetes mellitus (n = 32/8,693, 0.4%). Cryptococcus species was the most common (n = 8,428/8,693, 97.0%) causative organism. The most commonly used diagnostic modality was cerebrospinal (CSF) cultures (n = 4,390/6,830, 64.3%) for diffuse IcFIs, and MRI imaging (n = 12/30, 40%) for focal IcFIs. The most common treatment modality was medical management with antifungals only (n = 4,481/8,693, 51.6%). The most commonly used antifungal agent in paediatric, and adult patients was amphotericin B and fluconazole dual therapy (51.5% vs 44.9%). The overall mortality rate was high (n = 3,475/7,493, 46.3%), and similar for both adult and paediatric patients (47.8% vs 42.1%). CONCLUSION: Most IcFIs occurred in immunosuppressed individuals, and despite the new diagnostic techniques, CSF culture was mostly used in Africa. Antifungals regimens used was similar between children and adults. The outcome of IcFIs in Africa was poor for both paediatric and adult patients.

Presentation, Management, and Outcomes of Thoracic, Thoracolumbar, and Lumbar Spine Trauma in East Africa: A Cohort Study.

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.

Presentation, Management, and Outcomes of Traumatic Spinal Injuries Following Coconut Tree Fall in Tanzania: A Retrospective Study of 44 Cases.

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.

Regulation, approval, and access of spinal implants in low-middle-income countries: a narrative review and case study.

INTRODUCTION: Spinal implants play a vital role in healthcare delivery, and regulations are necessary to ensure their quality, approval, access, and use. In this article, we examine the current state of regulation and approval procedures for medical devices in low- and middle-income countries (LMICs), emphasizing the situation in Tanzania. AREAS COVERED: We conducted a systematic literature search and interviewed a local spine implant representative to investigate the approval, availability, and access of surgical and spinal implants in LMICs, particularly in Africa. Out of the 18 included articles, six referred to African regulations, with no mention of spinal implants. Our analysis revealed that LMICs face challenges in accessing implants due to affordability, poor supply chain, and lack of expertise for their application. However, surgeons have found alternative solutions, such as using lower-cost implants from Turkish manufacturers. The Tanzania Medical Devices and Drugs Authority oversees the local regulatory and approval process for implants. EXPERT OPINION: Regulation and accessibility of spinal implants in LMICs, particularly in Africa, are limited and negatively impact patient care and best medical practice. Potential solutions include capacity building within and collaboration among regulatory organizations to improve regulatory processes and allocating financial resources to qualitative and quantitative implant access.

Current Treatment Management of Aneurysmal Subarachnoid Hemorrhage with Prevailing Trends and Results in Tanzania: A Single-Center Experience at Muhimbili Orthopedic and Neurosurgery Institute.

BACKGROUND: In Africa, no cerebral aneurysm treatment guidelines exist. Epidemiology, management, and outcomes after aneurysmal subarachnoid hemorrhage (aSAH) remain poorly understood, with many underdiagnosed cases. Muhimbili Orthopaedic and Neurosurgery Institute (MOI) is the only neurosurgical referral center in Tanzania. The aim of this study is to describe the current aSAH management with regional outcomes and limitations. METHODS: Patients with aSAH confirmed by computed tomography/magnetic resonance angiography between February 2019 and June 2021 were retrospectively studied. The analyzed parameters included demographics, clinical/radiologic characteristics, injury characteristics, and the modified Rankin Scale (mRS) score. RESULTS: In total, 22 patients, with a female/male ratio of 1.4 and a median age of 54 years (interquartile range [IQR], 47.2-63 years) harboring 24 aneurysms were analyzed. Thirteen patients (59.1%) paid out of pocket. The median distance traveled by patients was 537 km (IQR, 34.7-635 km). The median time between admission and treatment was 12 days (IQR, 3.2-39 days). The most common symptoms were headache (n = 20; 90.9%) and high blood pressure (n = 10; 45.4%). Nine patients (40.9%) had Fisher grade 1 and 12 (54.5%) World Federation of Neurosurgical Societies grade I. The most common aneurysms were of the middle cerebral artery (7/29.2%). Fourteen patients (63.6%) underwent clipping; of those, only 4 (28.6%) were operated on within 72 hours. Mortality was 62.5% in the nonsurgical group. Among clipped patients, 78.6% showed favorable outcomes, with no mortality. Endovascular treatment is not available in Tanzania. CONCLUSIONS: To our best knowledge, this is the first study highlighting aSAH management in Tanzania, with its assets and shortcomings. Our data show pertinent differences among international treatment guidelines, with the resultant outcomes, such as high preoperative mortality resulting from delayed/postponed treatment. Regional difficult circumstances notwithstanding, our long-term goal is to significantly improve the overall management of aSAH in Tanzania.

INTRODUCTION: The aim of the protocol is to present the methodology of a scoping review that aims to synthesise up-to-date evidence on the management and outcomes of facial nerve palsy in low-income and middle-income countries (LMICs). METHODS AND ANALYSIS: The scoping review will be conducted per the Arksey and O'Malley's framework and the Joanna Briggs Institute Reviewers' Manual. The scoping review question, eligibility criteria and search strategy will be developed in accordance to the Population, Concept, and Context strategy. The search will be conducted in electronic bibliographic databases (Medline (OVID), Embase, WHO Global Index Medicus, Cochrane Library, Global Health, African Journals Online). The review will synthesise and report the findings with descriptive statistics and a narrative description of both quantitative and qualitative evidence. ETHICS AND DISSEMINATION: This scoping review does not require ethical approval. This protocol will describe the proposed scoping review that will map the evidence on the management and outcomes of facial nerve palsies in LMICs. The proposed review aims to collate and summarise published literature to inform policy-makers and healthcare organisations and governments and to identify knowledge gaps that will translate into future research priorities in LMICs.

Evaluating the Feasibility and Outcomes of a Scoliosis Surgical Camp in a Resource-Limited Setting in Sub-Saharan Africa.

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.

Awake Craniotomy in Africa: A Scoping Review of Literature and Proposed Solutions to Tackle Challenges.

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.

Effects of COVID-19 on Neurosurgical Service: Perspective from a Tertiary Medical Center in Nigeria.

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.

Health-Related Quality of Life Among Patients With Sickle Cell Disease in an Adult Hematology Clinic in a Tertiary Hospital in Lagos, Nigeria.

Background Sickle cell disease (SCD) is a genetic disease of public health concern. Improved quality healthcare has increased the life expectancy of these patients; however, they also face an increased frequency of vaso-occlusive crises and other SCD complications. These complications affect their quality of life, an area of care, which healthcare providers often overlook. We sought to determine the health-related quality of life among patients living with sickle cell disease in Lagos, Nigeria.  Materials and methods We conducted a cross-sectional study of 198 patients with sickle cell disease who attended the adult sickle cell clinic at a tertiary hospital in Lagos, Nigeria, during the period from October 1, 2018, to February 28, 2019. A self-administered questionnaire was used to obtain the clinical and socio-demographic characteristics of the patients and the 35-item Short-Form Health Survey (SF-36) questionnaire was used to determine their health-related quality of life (HRQoL). Determinants of HRQoL were established using bivariate and multivariate regression analysis.  Results The mean age of the 198 patients who participated in the study was 28.4±9.1 years, mean steady-state hemoglobin was 8.2 ± 1.3 g/dl, and 85 (42.9%) patients had a monthly income of 150 USD or less. In the previous year, 65 (32.1 %) and 33 (16.6%) patients, respectively, suffered one to two episodes (s) of acute bone pain crises and acute chest syndrome, and 43 (24.7%) had blood transfusion. Using the scoring system for SF-36 provided by RAND Health, role limitation due to physical health had the lowest median score of 50 (interquartile range {IQR}: 0-100). On bivariate analysis, bone pain crisis was associated with statistically significant low scores across all the 8 HRQoL domains of the SF36 questionnaire. Other variables, including having received blood transfusion, recent hospitalization, acute chest syndrome, lower level of income, and younger age, were also associated with significantly low scores. On regression analysis, bone pain crisis, level of income, and acute chest syndrome were found to be independent determinants of quality of life in the patients. Conclusion Sickle cell disease has a negative impact on the health-related quality of life of those affected. The presence of bone pain crisis is an important predictor of health-related quality of life in sickle cell disease patients. To improve patient outcomes, healthcare providers should take a holistic approach in evaluating and managing this disease, taking into cognizance how the complications and the financial burden of this disease impact the quality of life of affected patients.

Public awareness, knowledge of availability, and willingness to use neurosurgical care services in Sub-Saharan Africa: A cross-sectional study.

INTRODUCTION: Low- and middle-income countries bear the majority of neurosurgical disease burden and patients face significant barriers to seeking, reaching, and receiving care. We aimed to understand barriers to seeking care among adult Africans by evaluating the public perception, knowledge of availability, and readiness to use neurosurgical care services. METHODS: An e-survey was distributed among African adults who are not in the health sector or pursuing a health-related degree. Chi-square test and ANOVA were used for bivariate analysis and the alpha value was set at 0.05. Odds ratios and their 95% confidence intervals were calculated. RESULTS: Six hundred and sixty-two adults from 16 African countries aged 25.4 (95% CI: 25.0, 25.9) responded. The majority lived in urban settings (90.6%) and were English-speaking (76.4%) men (54.8%). Most respondents (76.3%) could define neurosurgery adequately. The most popular neurosurgical diseases were traumatic brain injury (76.3%), congenital brain and spine diseases (67.7%), and stroke (60.4%). Unwillingness to use or recommend in-country neurosurgical services was associated with rural dwelling (ß = -0.69, SE = 0.31, P = 0.03), lack of awareness about the availability of neurosurgeons in-country (ß = 1.02, SE = 0.20, P<0.001), and believing neurosurgery is expensive (ß = -1.49, SE = 0.36, P<0.001). CONCLUSION: Knowledge levels about neurosurgery are satisfactory; however, healthcare-seeking is negatively impacted by multiple factors.

Evaluating the Usefulness of YouTube as a Source of Patient Information for Neurosurgical Care in Africa: A Study Protocol.

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.

Cervical Decompression for Myelopathy in a Resource-Poor Region: Initial Experience.

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.

Assessment of the Knowledge of Risk Factors of Congenital Hydrocephalus among Mothers Attending Antenatal Clinics in a Rural Tertiary Hospital Irrua, Edo State.

Background One of the congenital central nervous system malformations with great impact on the mental and psychosocial development of children is congenital hydrocephalus and it happens to be one of the most common. A large vacuum exists between knowledge on maternal environmental risk factors associated with congenital hydrocephalus, most especially in our rural community which consists of a large segment of our society. Our study aimed to determine the knowledge and perception of mothers on factors existing in the maternal environment that potentially puts an increased risk of developing congenital hydrocephalus. Materials and Methods This was a cross-sectional study design spanning a period of 8 months (March 2018-October 2018), in which the knowledge and perception of the risk factors of congenital hydrocephalus among mothers attending antenatal clinic in Irrua specialist teaching hospital, a rural tertiary hospital in Irrua, Edo state, Nigeria, were assessed using a random sampling technique. Interviewer-administered questionnaires (reviewed and validated) were used. The data collected were entered and analyzed using SPSS version 21. Results The findings showed varying levels of knowledge of congenital hydrocephalus. Less than half (44.0%) of the respondents had poor knowledge, 34.5% had fair knowledge, and 21.6% had good knowledge. There was a statistically significant relationship between knowledge of congenital hydrocephalus and respondents' knowledge of the risk factors of congenital hydrocephalus. Most (52.6%) had good perception of the risk factors of congenital hydrocephalus, while 23.3% had poor perception. Conclusion This study revealed a fairly good knowledge of congenital hydrocephalus and its risk factors among mothers, most especially those with a good level of education.
