RESUMO
BACKGROUND: Metabolic bariatric surgery tourism continues to rise and has become a growing concern for bariatric surgeons globally. With varying degrees of regulation, counselling and success, those that develop complications may have to deal with a multitude of challenges often distant from their country of operation. The aim of this study was to characterize the barriers and facilitators influencing individuals to undergo metabolic bariatric surgery tourism, in order to better understand the implications to the National Health Service and other healthcare systems. METHODS: A systematic literature search, restricted to the English language, was performed to identify relevant studies. All studies were included until December 2022, the last search date. Study quality was assessed with the validated mixed-methods appraisal tool. A Braun and Clarke thematic analysis was undertaken to identify themes and subthemes. RESULTS: A total of five studies met the inclusion criteria. Identified themes included: availability, accessibility, cost, eligibility, reputation, and stigma; the available evidence was of varying quality. CONCLUSION: This work identifies a series of subthemes influencing the decision to undertake metabolic bariatric surgery tourism. The results highlight the limited literature available in understanding the complex motivational insights; the scale of the problem in the current healthcare system; cost and long-term outcomes. A National Emergency Bariatric Surgery audit would allow generation of more robust data to explore further the issues of clinical relationships and networks and to guide policy making.

BACKGROUND: Eosinophilic esophagitis (EoE) is a chronic antigen-mediated eosinophilic inflammatory disease isolated to the esophagus. As a clinicopathologic disorder, a diagnosis of EoE requires a constellation of clinical symptoms of esophageal dysfunction and histologic findings (at least 15 eosinophils/high-powered microscope field (eos/hpf)). Current guidelines no longer require the failure of response to proton pump inhibitor medications to establish a diagnosis of EoE, but continue to suggest the exclusion of other etiologies of esophageal eosinophilia. The treatment goals for EoE are improvement in clinical symptoms, resolution of esophageal eosinophilia and other histologic abnormalities, endoscopic improvement, improved quality of life, improved esophageal function, minimized adverse effects of treatment, and prevention of disease progression and subsequent complications. Currently, there is no cure for EoE, making long-term treatment necessary. Standard treatment modalities include dietary modifications, esophageal dilation, and pharmacologic therapy. Effective pharmacologic therapies include corticosteroids, rapidly emerging biological therapies, and proton pump inhibitor medications. OBJECTIVES: To evaluate the efficacy and safety of medical interventions for people with eosinophilic esophagitis. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, ClinicalTrials.gov, and WHO ICTRP to 3 March 2023. SELECTION CRITERIA: Randomized controlled trials (RCTs) comparing any medical intervention or food elimination diet for the treatment of eosinophilic esophagitis, either alone or in combination, to any other intervention (including placebo). DATA COLLECTION AND ANALYSIS: Pairs of review authors independently selected studies and conducted data extraction and risk of bias assessment. We expressed outcomes as a risk ratio (RR) and as the mean or standardized mean difference (MD/SMD) with 95% confidence interval (CI). We assessed the certainty of the evidence using GRADE. Our primary outcomes were: clinical, histological, and endoscopic improvement, and withdrawals due to adverse events. Secondary outcomes were: serious and total adverse events, and quality of life. MAIN RESULTS: We included 41 RCTs with 3253 participants. Eleven studies included pediatric patients while the rest recruited both children and adults. Four studies were in patients with inactive disease while the rest were in patients with active disease. We identified 19 intervention comparisons. In this abstract we present the results of the primary outcomes for the two main comparisons: corticosteroids versus placebo and biologics versus placebo, based on the prespecified outcomes defined of the primary studies. Fourteen studies compared corticosteroids to placebo for induction of remission and the risk of bias for these studies was mostly low. Corticosteroids may lead to slightly better clinical improvement (20% higher), measured dichotomously (risk ratio (RR) 1.74, 95% CI 1.08 to 2.80; 6 studies, 583 participants; number needed to treat for an additional beneficial outcome (NNTB) = 4; low certainty), and may lead to slightly better clinical improvement, measured continuously (standard mean difference (SMD) 0.51, 95% CI 0.17 to 0.85; 5 studies, 475 participants; low certainty). Corticosteroids lead to a large histological improvement (63% higher), measured dichotomously (RR 11.94, 95% CI 6.56 to 21.75; 12 studies, 978 participants; NNTB = 3; high certainty), and may lead to histological improvement, measured continuously (SMD 1.42, 95% CI 1.02 to 1.82; 5 studies, 449 participants; low certainty). Corticosteroids may lead to little to no endoscopic improvement, measured dichotomously (RR 2.60, 95% CI 0.82 to 8.19; 5 studies, 596 participants; low certainty), and may lead to endoscopic improvement, measured continuously (SMD 1.33, 95% CI 0.59 to 2.08; 5 studies, 596 participants; low certainty). Corticosteroids may lead to slightly fewer withdrawals due to adverse events (RR 0.64, 95% CI 0.43 to 0.96; 14 studies, 1032 participants; low certainty). Nine studies compared biologics to placebo for induction of remission. Biologics may result in little to no difference in clinical improvement, measured dichotomously (RR 1.14, 95% CI 0.85 to 1.52; 5 studies, 410 participants; low certainty), and may result in better clinical improvement, measured continuously (SMD 0.50, 95% CI 0.22 to 0.78; 7 studies, 387 participants; moderate certainty). Biologics result in better histological improvement (55% higher), measured dichotomously (RR 6.73, 95% CI 2.58 to 17.52; 8 studies, 925 participants; NNTB = 2; moderate certainty). We could not draw conclusions for this outcome when measured continuously (SMD 1.01, 95% CI 0.36 to 1.66; 6 studies, 370 participants; very low certainty). Biologics may result in little to no difference in endoscopic improvement, measured dichotomously (effect not estimable, low certainty). We cannot draw conclusions for this outcome when measured continuously (SMD 2.79, 95% CI 0.36 to 5.22; 1 study, 11 participants; very low certainty). There may be no difference in withdrawals due to adverse events (RR 1.55, 95% CI 0.88 to 2.74; 8 studies, 792 participants; low certainty). AUTHORS' CONCLUSIONS: Corticosteroids (as compared to placebo) may lead to clinical symptom improvement when reported both as dichotomous and continuous outcomes, from the primary study definitions. Corticosteroids lead to a large increase in histological improvement (dichotomous outcome) and may increase histological improvement (continuous outcome) when compared to placebo. Corticosteroids may or may not increase endoscopic improvement (depending on whether the outcome is measured dichotomously or continuously). Withdrawals due to adverse events (dichotomous outcome) may occur less frequently when corticosteroids are compared to placebo. Biologics (as compared to placebo) may not lead to clinical symptom improvement when reported as a dichotomous outcome and may lead to an increase in clinical symptom improvement (as a continuous outcome), from the primary study definitions. Biologics lead to a large increase in histological improvement when reported as a dichotomous outcome, but this is uncertain when reported as a continuous outcome, as compared to placebo. Biologics may not increase endoscopic improvement (dichotomous outcome), but this is uncertain when measured as a continuous outcome. Withdrawals due to adverse events as a dichotomous outcome may occur as frequently when biologics are compared to placebo.

BACKGROUND: Gross total resection remains the gold-standard approach for vestibular schwannomas (VS) when surgery is indicated. In select cases, incomplete resection (IR) becomes a desired alternative to preserve the facial nerve function and the patient's quality of life. While a lot of earlier studies described incompletely resected sporadic VSs as dormant, more recent studies reported a higher growth rate following IR, therefore an evaluation of the residual VS growth rates could have important implications for the follow-up treatment protocols and provide relevant information for neurosurgeons, neuro-otologists, neuropathologists, and radiologists. Although prognostic factors predicting preoperative VS growth have been previously investigated, these factors have not been investigated following IR. Our review aims to examine the growth rate of residual sporadic VS following IR and to examine variables associated with the regrowth of residual VS. METHODS: The review was conducted in accordance with the PRISMA guidelines. Six databases (MEDLINE (Ovid), Embase (Ovid), CINAHL Plus (EBSCO), Cochrane Central Register of Controlled Trials (CENTRAL), WHO International Clinical Trials Registry Platform and UK Clinical Trials Gateway (WHO ICTRP) were searched. Full-text articles analysing growth rates in at least ten patients who had residual VS after IR were assessed. We conducted a meta-analysis using a random-effects model via RevMan. RESULTS: 14 studies totalling 849 patients were included in the analysis. The mean planimetric growth rate was 1.57 mm/year (range 0.16-3.81 mm/year). The mean volumetric growth rate was 281.725 mm3/year (range 17.9-530.0 mm3/year). Age, sex, pre-operative tumour size/volume, cystic tumour sub-type, MIB-1 index, and intracanalicular tumour location were not associated with residual growth. Residual tumour size/volume was statistically significant to growth (OR = 0.65, 95% CI 0.47-0.90, p = 0.01). Radiological re-growth occurred in an average of 26.6% of cases (range 0-54.5%). CONCLUSION: From our analysis, only the residual tumour volume/size was associated with residual VS growth. Therefore, close postoperative surveillance for the first year, followed by an annual MRI scan for at least 5 years, and subsequently extended interval surveillance remains of utmost importance to monitor disease progression and provide timely surgical and adjuvant interventions. Our study shows that future work should be aimed at molecular and histological characteristics of residual VSs to aid prognostic understanding of growth.

INTRODUCTION: Randomised controlled trials (RCTs) of key therapies in inflammatory bowel disease (IBD) are often presented and available as abstracts for significant periods of time prior to full publication, often being employed to make strategic and clinical prescribing decisions. We compared the concordance of prepublication abstract-only reports and their respective full-text manuscripts. METHODS: Pairs of full-text manuscripts and their respective prepublication abstract-only reports for the same RCT outcomes, at the same time point of analysis were included. The RCTs were on treatments for IBD with full-text manuscripts published between 2010 and 2023. RESULTS: We found 77 pairs of full-text manuscripts and their prepublication abstract-only reports. There were significant mismatches in the reporting of stated planned outcomes (65/77 matched, p<0.001) and primary outcomes reported in their results sections (67/77, p<0.001); trial registrations (34/65, p<0.001); the number of randomised participants (49/77, p=0.18); participants reaching end of study (21/71, p<0.001) and primary outcome data (40/73, p<0.001). Authors conclusions matched (75/77, p=0.157). Authors did not provide explicit or implied justifications for the absence or non-concordance for any of the above items. CONCLUSIONS: Abstract-only reports have consistent issues with both limited reporting of key information and significant differences in data when compared with their later full-text publications. These are not related to further recruitment of patients or word count limitations and are never explained. As abstracts are often used in guidelines, reviews and stakeholder decision-making on prescribing, caution in their use is strongly suggested. Further work is needed to enhance minimum reporting standards in abstract-only works and ensure consistency with final published papers.

INTRODUCTION: Hydrocephalus and myelomeningocele (MMC) place disproportionate burdens of disease on low-income and middle-income countries (LMICs). MMC-associated hydrocephalus and its sequelae result in a spectrum of severely devastating clinical manifestations, for which LMICs are disproportionately unprepared in terms of human, capital and technological resources. This study aims to review and compare the management and outcomes of infant MMC-associated hydrocephalus in LMICs and high-income countries. METHODS AND ANALYSIS: This systematic review and meta-analysis will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. The following databases will be searched without restrictions on language, publication date or country of origin: EMBASE, MEDLINE, The Cochrane Library, Global Index Medicus, African Journals Online and SciELO. All peer-reviewed studies of primary data reporting management and outcomes of infant MMC-associated hydrocephalus will be included. Where high-quality homogeneous studies exist, meta-analyses will be conducted to compare the management and outcomes of MMC-associated hydrocephalus across socioeconomic and geographical regions of the world. The primary outcome will be treatment failure of the first-line hydrocephalus treatment, which we defined operationally as the performance of a second intervention for the same reason as the first. Secondary outcomes include time to failure, rates of mortality and postoperative complications. ETHICS AND DISSEMINATION: Ethical approval was not applicable because this study does not involve human participants. Dissemination strategies will include publication in a peer-reviewed journal, oral and poster presentations at conferences and an interactive web application to facilitate interaction with the findings and promote the discussion and sharing of findings on social media. PROSPERO REGISTRATION NUMBER: CRD42021285850.

BACKGROUND: Atypical teratoid/rhabdoid tumor (ATRT) is a rare malignant neoplasm in the pediatric population. ATRT is characterized by rhabdoid cells combined with the loss of either the INI1 (integrase interactor 1) or BRG1 (Brahma-related gene-1) protein. OBJECTIVE: To systematically review and analyze patient and tumor characteristics, prognosis, and impact of treatment on survival in pediatric patients with ATRT confirmed by alterations in INI1 or BRG1. This systematic review is the first to include only pediatric cases of ATRT confirmed with either INI1 or BRG1 alterations. METHODS: MEDLINE was searched using the terms "atypical teratoid/rhabdoid tumor" AND "paediatric/pediatric." Cases were included if confirmed by loss of INI1 or BRG1. The extracted dataset was analyzed using descriptive statistics, log-rank test, and Kaplan-Meier survival analysis via SPSS. RESULTS: A total of 38 articles were included in this study. The average age at diagnosis was 3 years. The most common locations reported are the supratentorial region and cerebral hemispheres. Ninety-three patients were reported to show evidence of dissemination. The average overall survival was 29 months. A significant difference in survival was noted between the tumor location groups, particularly worse outcomes for patients with spinal ATRT (P < 0.001). Extent of resection and adjuvant therapy were significant for survival (χ2 = 10.107, P = 0.018 and χ2 = 20.38, P < 0.0001, respectively). CONCLUSIONS: ATRT of the central nervous system in pediatric populations is a rare neoplasm associated with a poor prognosis in most patients. Future studies should be directed to find a standardized treatment protocol.

BACKGROUND: Traumatic spinal cord injury (TSCI) is a subset of neurotrauma, which is a significant contributor to global trauma mortality and morbidity in children. The management and outcomes of pediatric TSCI in low- and middle-income countries (LMICs) is unknown. We conducted a scoping review to characterize the methods of management and outcomes of TSCI in LMICs. METHODS: MEDLINE, Embase, and Global Index Medicus were searched from database inception to February 15, 2021. Studies reporting management or outcomes of pediatric TSCI in LMICs were included. Pooled statistics were calculated using measures of central tendency and spread. RESULTS: A total of 1171 studies were identified, of which 5 were included. A total of 212 patients were included in our review with age of participants ranging from 2.5 to 18 years (mean, 15.4 years). Most patients were male (n = 162; 76.4%). The commonest cited cause of injury were falls (n = 104/212; 49.1%). The most common level of injury was cervical (n = 83; 39.2%). Most patients underwent surgery (n = 134/212; 63.2%). The extent of injury was quantified and classified using the American Spinal Injury Association chart in only 1 study. Long-term management data were not present in any of the included studies. CONCLUSIONS: There is a scarcity of studies reporting the management and outcome of pediatric TSCI in LMICs. The paucity of studies in this domain provides insufficient data to be compared, reducing the ability to draw a strong conclusion. This situation hinders the development of guidelines to inform best practice.

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.
RESUMO
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. SCOPING REVIEW REGISTRATION: The protocol has been registered on the Open Science Framework (OSF; registration link: https://doi.org/10.17605/OSF.IO/E732G). HIGHLIGHTS: LGGs account for 17% to 22% of total brain tumours and have a median survival time between 5.6 and 13.3 years.Despite many recent advancements in the management of LGGs, there is a paucity in the data within the African landscape.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 and policymaking efforts.
RESUMO
OBJECTIVE: International medical electives are an essential part of medical education and popular among medical students. During the COVID-19 pandemic, however, many students had assistantship placements postponed and electives cancelled. Educational institutions switched face-to-face campus-based teaching to virtual platforms. Although it is conceivable that international medical electives were particularly affected by this development, numerical data on this phenomenon is yet scarce. To investigate how the COVID-19 pandemic influenced the clinical elective behavior of German-speaking medical students, we systematically analyzed two large German online databases (Famulatur-Ranking and PJ-Ranking) cataloging medical elective experience testimonies. RESULTS: The COVID-19 pandemic substantially reduced the number of German medical students undertaking abroad medical electives. Between 2018 and 2020, a total of 10,976 reports were uploaded to both databases. We observed a notable decline in abroad elective reports in 2020. Prior to the COVID-19 pandemic, almost 5% of reports uploaded to "PJ-ranking" covered an international medical elective. This number dropped to 1.68% in 2020. Analyzing "Famulaturranking", we observed a comparable phenomenon. While 4.74% of reports in 2019 covered an international elective, the number dropped to 2.02% in 2020. The long-term consequences of this phenomenon will be subject to future research.

We present the case of pleiomorphic liposarcoma in the medial compartment of the thigh of a 59-year-old female patient. The lump was noticed eight months prior to presentation and had gradually increased in size, leading to pressure symptoms in her thigh. Although painless initially, the lump eventually became tender prompting her to seek surgical attention. At the plastic surgery clinic, she was advised to get an MRI, which revealed an irregular but well-defined mass lesion measuring 8.2 x 6.6 x 4.3 cm. The mass did not have any manifestations in the surrounding structures. A wide excisional biopsy was then performed, and multiple sections were processed for histopathological analysis, confirming a diagnosis of epithelioid variant of pleomorphic liposarcoma.
RESUMO
INTRODUCTION: Neurosurgical equipment donation from high-income countries (HICs) to low-and-middle income countries (LMICs) exists. However, there is currently no published literature on whether there is a need for neurosurgical equipment donations or how to design equipment donation programmes that meet the needs of LMIC neurosurgeons. The primary aims of this study were to explore: (1) the need for the donation of neurosurgical equipment from the UK and Ireland to LMICs within the African continent, and (2) the ways through which neurosurgical equipment donations could meet the needs of LMIC neurosurgeons. METHODS: This was a qualitative study using semi-structured, one-on-one, audio-recorded interviews. Purposive sampling was used to recruit and interview consultants or attending neurosurgeons from Ireland, the UK and LMICs in Africa in a continuous process until data saturation. Interviews were conducted by members of the Association of Future African Neurosurgeons during March 2021. Qualitative analysis used a thematic approach using open and axial coding. RESULTS: Five HIC and 3 LMIC neurosurgeons were interviewed. Five overarching themes were identified: (1) inequality of access to neurosurgical equipment, (2) identifying specific neurosurgical equipment needs, (3) importance of organisations, (4) partnerships between LMIC and HIC centres, and (5) donations are insufficient in isolation. CONCLUSION: There is a need for greater access to neurosurgical equipment in LMICs. It is unclear if neurosurgical equipment donations are the optimal solution to this issue. Other solutions that are not linked to dependency need to be explored and executed. Collaborative relationships between LMICs and HICs better ensures that neurosurgical equipment donations meet the needs of the recipients. These relationships may be best created within an organisation framework that has the logistical capabilities of coordinating international equipment donation and providing a quality control measure.
RESUMO
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.
RESUMO
Background: The COVID-19 pandemic has caused a surge in research activity while restricting data collection methods, leading to a rise in survey-based studies. Anecdotal evidence suggests this increase in neurosurgical survey dissemination has led to a phenomenon of survey fatigue, characterized by decreased response rates and reducing the quality of data. This paper aims to analyze the effect of COVID-19 on neurosurgery surveys and their response rates, and suggest strategies for improving survey data collection. Methods: A search was conducted on March 20, 2021, on Medline and EMBASE. This included the terms "neurosurgery," "cranial surgery," "spine surgery," and "survey" and identified surveys written in English, on a neurosurgical topic, distributed to neurosurgeons, trainees, and medical students. Results were screened by two authors according to these inclusion criteria, and included articles were used for data extraction, univariable, and bivariable analysis with Fisher's exact-test, Wilcoxon rank-sum test, and Spearman's correlation. Results: We included 255 articles in our analysis, 32.3% of which were published during the COVID-19 pandemic. Surveys had an average of 25.6 (95% CI = 22.5-28.8) questions and were mostly multiple choice (78.8%). They were disseminated primarily by email (75.3%, 95% CI = 70.0-80.6%) and there was a significant increase in dissemination via social media during the pandemic (OR = 3.50, 95% CI = 1.30-12.0). COVID-19 surveys were distributed to more geographical regions than pre-pandemic surveys (2.1 vs. 1.5, P = 0.01) and had higher total responses (247.0 vs. 206.4, P = 0.01), but lower response rates (34.5 vs. 51.0%, P < 0.001) than pre-COVID-19 surveys. Conclusion: The rise in neurosurgical survey distribution during the COVID-19 pandemic has led to survey fatigue, reduced response rates, and data collection quality. We advocate for population targeting to avoid over-researching, collaboration between research teams to minimize duplicate surveys, and communication with respondents to convey study importance, and we suggest further strategies to improve response rates in neurosurgery survey data collection.
RESUMO
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.
