Although nontraumatic diseases affect fewer people than traumatic neurosurgical diseases, they require expertise more often. The authors sought to understand the barriers to nontraumatic ...neurosurgical diseases (NTNSDs) in a country with limited access to neurosurgical care.
This cross-sectional study with retrospective data collection was carried out in 2 Cameroonian reference hospitals for a year. Multiple imputations were used to generate data for the missing variables—death and discharge with sequelae. Bivariate relationships were evaluated using the chi-square and Mann-Whitney U tests. Odds ratios were equally calculated, and the results were considered significant for a P value <0.05.
NTNSDs represented 44.1% of neurosurgical activity. Our study included 177 patients with a mean age of 43.7 ± 21.2 years. More than half (53.1%) were female, 78% lived in a different region from that of the neurosurgical center, 18.1% had health insurance, 39.5% were referrals, and the mean symptom-to-admission delay was 409.0 ± 1301.7 days. Most (87%) of the patients had undergone at least 1 of the diagnostic examinations prescribed to them. Men (P = 0.029) and rural dwellers (P = 0.017) had shorter symptom-to-admission delays than women and urban dwellers, respectively. The mean length of stay was 18.2 ± 13.4, and 80.8% of patients were treated surgically. Thirty-one (17.5%) patients died in the hospital: 9 were treated surgically, and 22 were treated conservatively or expectantly.
Patients with NTNSD present at the definitive care facilities late. This delay is attributable to financial and geographic barriers.
The burden of traumatic brain injury (TBI) disproportionately affects low- and middle-income countries. In Cameroon, the estimated annual incidence rate is 572 cases per 100,000 people. This study ...investigated factors associated with adverse outcomes in the management of Cameroonian patients with TBI.
This cross-sectional study included all patients with TBI treated between January 1 and December 31, 2018, at 2 Cameroonian referral hospitals. Sociodemographic and clinical data were extracted from patient charts and admission registries and analyzed with SPSS v.26. Independent t tests, odds ratios, and cumulative mortality hazard rates were computed. A P-value <0.05 was considered statistically significant. Also, binomial regression analyses were calculated.
One hundred seventy-one patients aged 38.63 ± 20.46 years old received treatment for TBI. Most patients were male (78.9%), Cameroonian (98.2%), from urban areas (75.4%), and uninsured (88.8%). The average admission length was 11.23 ± 10.71 days, during which 27.5% of patients received surgical treatment while 72.5% received non-surgical (conservative) management. From postdischarge day 12 onwards, surgically-treated patients had a greater cumulative mortality hazard rate than conservatively-treated patients. By 28 days postdischarge, 66.1% of patients had recovered completely Glasgow Outcome Scale (GOS) = 5, 23.4% had a disability (GOS = 2–4), and 10.5% expired (GOS = 1). Complete recovery was associated with the absence of severe TBI (B = −1.42, standard error SE = 0.52, P = 0.006), disability was associated with increased injury-to-admission delay (B = −1.27, SE = 0.48, P = 0.009), and death was associated with severe TBI (B = 3.16, SE = 0.73, P < 0.001).
We identified factors associated with unfavorable outcomes among Cameroonian patients with TBI. These results can inform triage and referral practices and aid policymakers in developing context-specific prehospital guidelines.
There is no comprehensive report of neurosurgery postgraduate education in Africa. This narrative review aimed to map out the landscape of neurosurgery training in Africa and highlight similarities ...and differences in training.
The keywords “neurosurgery,” “education,” and “Africa” were searched on PubMed and Google Scholar from inception to January 17, 2021. Next, a complementary hand search was conducted on Google using the keywords “neurosurgery,” “residency,” and the individual African countries in English and official languages. The relevant data were extracted and compiled into a narrative review.
A total of 76 African training programs that recruit more than 168 trainees each year were identified. Less than half (40.7%, n = 22) of African countries have at least 1 neurosurgery training program. Egypt (n = 15), Algeria (n = 14), and Nigeria (n = 10) have the highest number of training programs, whereas Algeria (0.33), Egypt (0.15), and Libya (0.15) have the highest number of training programs per 1 million inhabitants. The College of Surgeons of East, Central, and Southern Africa has 16 programs in 8 countries, whereas the West African College of Surgeons has 17 accredited programs in 3 countries. The duration of training varies between 4 and 8 years. There is limited information available in the public domain and academic literature about subspecialty fellowships in Africa.
This review provides prospective applicants and African and global neurosurgery stakeholders with information to advocate for increased investment in African neurosurgery training programs.
Introduction. Most cases of paroxysmal sympathetic hyperactivity (PSH) result from traumatic brain injury (TBI). Little is known about its pathophysiology and treatment, and several neuroprotective ...drugs are used including beta-blockers. The aim of our study is to collate existing evidence of the role of beta-blockers in the treatment of PSH. Methods. We searched MEDLINE, ResearchGate, and Google Scholar, for keywords related to PSH and the role of beta-blockers in moderate-to-severe TBI on September 23, 2020. Two authors blindly screened the articles found with Rayyan. Both resolved their conflicts by mutual consent. If no solution was found, a third author was consulted. Simple descriptive data analysis was performed and the results were presented both in a narrative and tabular form. Results. Of the 19 items found, 10 met the criteria for inclusion. 50% were systematic reviews without meta-analysis, 40% were observational studies, and 10% were experimental studies. Propranolol was the main beta-blocker found in 80% of the studies and was the only molecule used in the treatment of paroxysmal sympathetic hyperactivity in 40% of the included studies. Only two studies evaluated and showed a significant association between beta-blockers and mortality rate (5.1% vs. 10.8%; P=0.03), (3% vs. 15%; P=0.002), respectively. Conclusion. Propranolol is the beta-blocker that has been shown to be effective in reducing the length of stay and mortality rate in moderate-severe traumatic brain injury patients with PSH. However, further studies are needed to precisely define the terms and conditions of its use.
Traumatic brain injury (TBI) is the most common neurosurgical condition globally. In Cameroon, there are 572 cases of TBI per 100,000 people, but <40% of Cameroonians live within 4 hours of a ...neurosurgical facility. We sought to understand the clinical outcomes at a neurosurgical center in Central Cameroon.
This cross-sectional study was conducted at the largest neurosurgical center of Cameroon, the Yaounde Central Hospital. Data included 100 consecutive patients undergoing an intervention 72 hours after their injury from February 1, 2015 to February 1, 2019. Patients with missing data or undergoing surgery >72 hours after injury were excluded. Analyses of covariance were performed, and a P value >0.05 was considered significant. A Kaplan-Meier survival curve was computed.
The patients had a mean age of 31.3 ± 17.4 years, with a male predominance of 91.0%, and the principal mechanism of injury was road traffic accidents (68.0%). Only 11% arrived via ambulance, and 36.0% were admitted <3 hours after the traumatic event. The postoperative mortality was 15.0%, mean survival was 25.0 postoperative days (95% confidence interval, 23.42–26.52), and the mean Glasgow Outcome Scale score at 28 days was 3.9 ± 1.4.
Most patients with TBI undergoing neurosurgery 72 hours after injury in Cameroon arrive at the hospital late and have a high mortality risk during the first postoperative week. Investments in prehospital care should be made to improve surgical outcomes.
Introduction:
Although the past decade has seen a substantial increase in African neurosurgeons' academic productivity, productivity remains low compared to their colleagues from other regions. ...Aspiring neurosurgeons can contribute to the academic neurosurgery workforce by taking care of less technical and time-consuming research tasks. Fortunately, global neurosurgery institutions have also made efforts to increase research exposure and scholarly output in academic global neurosurgery. The Association of Future African Neurosurgeons (AFAN) created a research incubator for aspiring academic global neurosurgeons in Africa to provide enrollees with mentorship, skills, and experience. This study assesses and reports the activities and results of the research incubator.
Methods:
Aspiring academic global neurosurgeons were enrolled in the AFAN Research Incubator Program (ARIP), whose primary objective was to provide enrollees with foundational skills in all aspects of the research cycle. ARIP enrollees participated in didactic and practical activities with the aim of publishing ≥1 article and presenting ≥1 abstracts at international conferences in one year.
Results:
Fifteen AFAN members aged 25.0 ± 3.0 years enrolled in ARIP: 7 (46.7%) medical students, 4 (26.7%) general practitioners, and 4 (26.7%) residents. Eleven (73.3%) were male, 6 (40.0%) were from Cameroon and 6 (40.0%) had no previous research experience. Two (13.3%) enrollees dropped out. ARIP enrollees published a total of 28 articles, and enrollees published a median of 1.0 (IQR = 2) first-author articles on neurosurgical system strengthening. Additionally, ARIP enrollees presented 20 abstracts with a median of one abstract (IQR = 3.0).
Conclusion:
South-South research collaborations like ARIP can contribute to improving global neurosurgery research capacity and output. These collaborations can set up the foundations for robust research in low- and middle-income countries.
Three million African patients need a neurosurgical consultation every year, but there are not enough neurosurgeons to meet this need. Efforts have been made to increase the neurosurgical capacity ...through the creation of training programs in Africa. Although these programs have been successful, there is still a long way to go. Aspiring African neurosurgeons (AANs) will become neurosurgeons in the future if they are given the resources and opportunities. The authors set out to understand the perceptions, needs, and difficulties faced by AANs.
An e-survey containing 45 questions was created using Google Forms and distributed via social media. The survey was anonymous, and it was distributed from June 2, 2020, to June 16, 2020. Summary descriptive statistics and the Chi-Square test were calculated. The p-value was considered to be significant below .05.
A total of 221 AANs aged 23.5 ± 3.3 years and from 22 African countries responded to the survey. Most were male (66.1%) and medical students (84.6%). Few had assisted a neurosurgical intervention in-person (24.9%), had a mentor (29.0%) or attended a journal club (10.3%). A small proportion was unwilling to train in their home country (19.5%) or a neighboring country (16.3%). The top three reasons for choosing neurosurgery were prestige, advice from a family member, and projected income. Also, respondents felt neurosurgery was expensive.
AANs are passionate about neurosurgery but lack the information, guidance, or opportunities to fulfil their wish.
Low- and middle-income countries (LMICs) bear the majority of the neurosurgical burden of diseases but lack the resources to meet these needs.
As we increase access to neurosurgical care in LMICs, we ...must understand patient attitudes toward neurosurgery.
PubMed, LILACS, and African Journals Online databases were searched systematically from inception to January 4, 2020, for studies on neurosurgical patient perceptions in LMICs. The articles found were blindly reviewed with Rayyan by two authors. The two authors resolved conflicts between themselves, and when this was not possible, a third reviewer was consulted. All the articles included were then appraised, and the results were summarized.
Six of the 1,175 articles met the inclusion criteria. The studies were set in Brazil, Ethiopia, India, Nigeria, South Korea, and Sub-Saharan Africa. Four of the studies (50%) were phenomenological studies, and the other two were grounded theory and narrative. The studies identified patient attitudes toward neurosurgical practitioners, diseases, and interventions. Ethiopian and Nigerian patients believed cranial diseases to be otherworldly and resorted to traditional medicine or spiritual healing first, whereas Brazilian patients were more comfortable with cranial diseases and even more so if they had had a previous craniotomy. The Indian paper was a recount of a neurosurgeon's experience as a spine patient.
There are few studies on neurosurgery patient perception in LMICs. LMIC neurosurgeons should be encouraged to study their patient beliefs concerning neurosurgical diseases and interventions, as this can explain health-seeking behaviors.
Intracranial suppurations account for a significant proportion of intracranial masses in low- and middle-income countries (LMICs), particularly among children. The development of better imaging ...equipment, antibiotics, and surgical techniques has enabled significant progress in detecting and treating intracranial abscesses. However, it is unclear whether these advances are accessible and utilised by LMICs. In this review, we aimed to describe the landscape of paediatric intracranial suppurations in LMICs.
This scoping review was conducted using the Arksey and O'Malley framework. MEDLINE, EMBASE, WHO Global Index Medicus, AJOL and Google scholar were searched for relevant articles from database inception to January 18th, 2021. Publications in English and French were included.
Of the 1,011 records identified, 75 were included. The studies, on average, included 18.8 (95% CI = 8.4-29.1) children (mean age: 8.2 years). Most children were male (62.2%, 95% CI = 28.7-95.7%). Intracranial suppurations were most commonly (46.5%) located in the supratentorial brain parenchyma. The most prevalent causative mechanism was otitis (37.4%) with streptococcus species being the most common causative organism (19.4%). CT scan (71.2%) was most commonly used as a diagnostic tool and antibiotics were given to all patients. Symptoms resolved in 23.7% and improved in 15.3% of patients. The morbidity rate was 6.9%, 18.8% of patients were readmitted, and the mortality rate was 11.0%.
Most intracranial suppurations were complications of preventable infections and despite MRI being the gold standard for detecting intracranial suppurations, CT scans were mostly used in LMICs. These differences are likely a consequence of inequities in healthcare and have resulted in a high mortality rate in LMICs.
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.
To review the published literature on AC in African countries, identify challenges, and propose pragmatic solutions by practicing neurosurgeons in Africa.
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.
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.
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.
