Introduction: 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.Methods: 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.Results: 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%.Conclusion: 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.
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.
Rationale: Interventional neurovascular procedures are effective in lowering the burden of mortality and complications resulting from aneurysmal subarachnoid hemorrhage (aSAH). Despite the wide uptake of interventional neurovascular procedures in high-income countries, access to care in low- and middle-income countries remains limited, and little is known about accessibility in Africa. In this survey, we decided to assess access to diagnostic tools and treatment of aSAH in Africa.Methodology: A Google form e-survey was distributed to African neurosurgery centers accepting responses from January 4th to March 21st 2021. Data on accessibility to diagnostic tools, treatment methodologies, and interventional neuroradiology personnel in African centers were collected. Ninety five percent confidence intervals were computed for each variable.Results: Data was received from 36 neurosurgical centers in 16 African countries (16/54, 30%). Most centers were public institutions. Ninety four percent of the centers had the necessary resources for a lumbar puncture (LP) and a laboratory for the diagnosis of aSAH. Most centers had at least one computed tomography (CT) scanner, 81% of the centers had access to CT angiography and some had access to conventional angiography. Forty seven percent of the centers could obtain a head CT within 2 h of presentation in an emergency. Sixty one percent of centers provided clipping of intracranial aneurysms whilst only 22% of centers could perform the endovascular treatment. Sixty four percent of centers did not have an endovascular specialist.Conclusion: This survey highlights health inequity in access to endovascular treatment for aSAH. Lack of diagnostic tools to identify an aneurysm and a shortfall of qualified endovascular specialists are prime reasons for this. Our findings can inform health system strengthening policies including the acquisition of equipment and capacity building in Africa.
Introduction Despite recent advancements in the management of low-grade gliomas (LGGs), there is a paucity in the data within the African landscape. We aim to evaluate the epidemiology, management, and outcomes of LGGs in Africa. Methods Systematic searches of MEDLINE, Embase and African Journals Online were performed from database inception to January 27, 2021, for studies reporting on LGGs in Africa. Pooled statistics were calculated using measures of central tendency and spread. Results 554 unique studies were identified, of which 25 were included. The mean age of patients was 15.7 years (95% confidence interval (CI): 11.8–19.6) and 56.4% were male (95% CI: 55.6–62.6%). Most patients had solitary lesions (86.0%, 95% CI: 82.8–89.1%) located in the infratentorial region (71.6%, 95% CI: 66.1–77.1%). Most LGGs received histopathological diagnosis (71.7%, 95% CI: 69.2–74.2%) and astrocytoma was the most common type (81.1%, 95% CI: 78.5–83.7%). 37 patients had awake surgery (3.1%, 95% CI: 2.0–4.0%) and there were no reports of molecular pathology testing, intraoperative neuroimaging, or 5-aminolevulinic acid. Gross total resection was achieved in 74.8% (95% CI: 69.6–80.0%) and there was a recurrence rate of 1.7% (95% CI: 0.9–2.4%), with a mean follow-up of 19.4 months (95% CI: 6.9–31.9). Conclusion LGGs are underreported in Africa. We found a lag in the uptake of techniques established in high-income countries for improving patient outcomes. Future efforts will require further training and funding in molecular pathology testing and advanced surgical adjuncts.
Background: Over the last decade, many advancements have been made in the management of low-grade gliomas (LGGs). Overall survival outcomes are correlated with factors such as postoperative residual volumes and specific tumor biomolecular profiles such as IDH mutation status. It is unclear whether these advancements have benefited LGG patients in Africa. This scoping review protocol outlines how the authors will evaluate the epidemiology, presentations, management and outcomes of LGGs in Africa.Methods: MEDLINE, Embase and African Journals Online will be searched from database inception to date in order to identify the relevant studies. Patients of all ages with histologically and/or radiologically confirmed LGGs that were managed in an African country will be included. Surgical and chemoradiation management of LGG tumours will be considered. Original research, reviews, commentaries, editorials and case reports will be included.Results: Primary outcomes of the review will include LGG management, morbidity and mortality. Secondary outcomes include epidemiology and recurrence of LGGs.Discussion: This scoping review will be the first to evaluate the current landscape of LGG management and outcomes in Africa, highlighting pertinent themes that may be used to guide further research as well as health system strengthening efforts by policymakers and stakeholders.
Stab wounds to the cervical spine are less common than injuries from road accidents, sports injuries, and falls. The presence of vital, vascular, neural, respiratory, and digestive structures in the neck region mean that this kind of spinal injury is generally critical, and its management is a challenge. We report a unique case of a previously healthy 17-year-old adolescent admitted for quadriplegia secondary to a stab wound to the cervical spine at the C4C5 level. There was no surgical indication. The patient underwent physiotherapy. He showed spontaneous neurological improvement two weeks later and was able to sit on his own and to walk about three months of physical rehabilitation.
The ossifying fibroma is a benign fibro-osseous tumor rarely affecting the skull base. The incidence of ossifying fibroma itself is uncommon. It is considered to be an aggressive and fast-growing bone lesion. Early detection and complete surgical removal are essential to deal with its aggressive nature and recurrence. We report a case of a 20-year-old man admitted for the management of ossifying fibroma of the orbital roof extending inside the orbit mimicking meningioma and revealed by a progressive proptosis and headache. The patient underwent surgery for the subtotal removal of the tumor with its frontal infiltration with a good outcome. All meningiomas like tumors are not meningiomas and other tumors such as ossifying fibroma might be mistaken for meningioma and even get confirmation from the pathological anatomy study. Need be for these tumors to be looked at more closely for better therapeutic decision-making.
