RESUMO

INTRODUCTION: Central to neurosurgical care, neurosurgical education is particularly needed in low- and middle-income countries (LMICs), where opportunities for neurosurgical training are limited due to social and economic constraints and an inadequate workforce. The present paper aims (1) to evaluate the validity and usability of a cadaver-free hybrid system in the context of LMICs and (2) to report their learning needs and whether the courses meet those needs via a comprehensive survey. METHODS: From April to November 2021, a non-profit initiative consisting of a series of innovative cadaver-free courses based on virtual and practical training was organized. This project emerged from a collaboration between the Young Neurosurgeons Forum of the World Federation of Neurological Societies (WFNS), the NIHR Global Health Research Group on Neurotrauma, and UpSurgeOn, an Italian hi-tech company specialized in simulation technologies, creator of the UpSurgeOn Box, a hyper-realistic simulator of cranial approaches fused with augmented reality. Over that period, 11 cadaver-free courses were held in LMICs using remote hands-on Box simulators. RESULTS: One hundred sixty-eight participants completed an online survey after course completion of the course. The anatomical accuracy of simulators was overall rated high by the participant. The simulator provided a challenging but manageable learning curve, and 86% of participants found the Box to be very intuitive to use. When asked if the sequence of mental training (app), hybrid training (Augmented Reality), and manual training (the Box) was an effective method of training to fill the gap between theoretical knowledge and practice on a real patient/cadaver, 83% of participants agreed. Overall, the hands-on activities on the simulators have been satisfactory, as well as the integration between physical and digital simulation. CONCLUSIONS: This project demonstrated that a cadaver-free hybrid (virtual/hands-on) training system could potentially participate in accelerating the learning curve of neurosurgical residents, especially in the setting of limited training possibilities such as LMICs, which were only worsened during the COVID-19 pandemic.

RESUMO

BACKGROUND: Traumatic brain injury (TBI) and stroke have devastating consequences and are major global public health issues. For patients that require a cerebral decompression after suffering a TBI or stroke, a decompressive craniectomy (DC) is the most commonly performed operation. However, retrospective non-randomized studies suggest that a decompressive craniotomy (DCO; also known as hinge or floating craniotomy), where a bone flap is replaced but not rigidly fixed, has comparable outcomes to DC. The primary aim of this project was to understand the current extent of usage of DC and DCO for TBI and stroke worldwide. METHOD: A questionnaire was designed and disseminated globally via emailing lists and social media to practicing neurosurgeons between June and November 2019. RESULTS: We received 208 responses from 60 countries [40 low- and middle-income countries (LMICs)]. DC is used more frequently than DCO, however, about one-quarter of respondents are using a DCO in more than 25% of their patients. The three top indications for a DCO were an acute subdural hematoma (ASDH) and a GCS of 9-12, ASDH with contusions and a GCS of 3-8, and ASDH with contusions and a GCS of 9-12. There were 8 DCO techniques used with the majority (60/125) loosely tying sutures to the bone flap. The majority (82%) stated that they were interested in collaborating on a randomized trial of DCO vs. DC. CONCLUSION: Our results show that DCO is a procedure carried out for TBI and stroke, especially in LMICs, and most commonly for an ASDH. The majority of the respondents were interested in collaborating on a is a future randomized trial.

RESUMO

INTRODUCTION: Low-income and middle-income countries (LMICs) face the greatest burden of neurotrauma. However, most of the research published in scientific journals originates from high-income countries, suggesting those in LMICs are either not engaging in research or are not publishing it. Evidence originating in high-income countries may not be generalisable to LMICs; therefore, it is important to nurture research capacity in LMICs so that a relevant evidence base can be developed. However, little is published about specific challenges or contextual issues relevant to increasing research activity of neurosurgeons in LMICs. Therefore, the aim of this study was to understand neurosurgeons' experiences of, aspirations for and ability to conduct and disseminate clinical research in LMICs. METHODS AND ANALYSIS: This is a pragmatic qualitative study situated within the naturalistic paradigm using focus groups and interviews with a purposive sample of neurosurgeons from LMICs. First, we will conduct asynchronous online focus groups with 36 neurosurgeons to broadly explore issues relevant to the study aim. Second, we will select 20 participants for follow-up semistructured interviews to explore concepts in more depth and detail than could be achieved in the focus group. Interviews will be audio-recorded and transcribed verbatim. A thematic analysis will be conducted following Braun and Clarke's six stages and will be supported by NVIVO software. ETHICS AND DISSEMINATION: The University of Cambridge Psychology Research Ethics Committee reviewed this study and provided a favourable opinion in January 2020 (REF PRE.2020.006). Participants will provide informed consent, be able to withdraw at any time and will have their contributions kept confidential. The findings of the study will be shared with relevant stakeholders and disseminated in conference presentations and journal publications.

RESUMO

BACKGROUND: Neurotrauma is an important global health problem. The largest cause of neurotrauma worldwide is road traffic collisions (RTCs), particularly in low- and middle-income countries (LMICs). Neurotrauma and RTCs are preventable, and many preventative interventions have been implemented over the last decades, especially in high-income countries (HICs). However, it is uncertain if these strategies are applicable globally due to variations in environment, resources, population, culture and infrastructure. Given this issue, this scoping review aims to identify, quantify and describe the evidence on approaches in neurotrauma and RTCs prevention, and ascertain contextual factors that influence their implementation in LMICs and HICs. METHODS: A systematic search was conducted using five electronic databases (MEDLINE, EMBASE, CINAHL, Global Health on EBSCO host, Cochrane Database of Systematic Reviews), grey literature databases, government and non-government websites, as well as bibliographic and citation searching of selected articles. The extracted data were presented using figures, tables, and accompanying narrative summaries. The results of this review were reported using the PRISMA Extension for Scoping Reviews (PRISMA-ScR). RESULTS: A total of 411 publications met the inclusion criteria, including 349 primary studies and 62 reviews. More than 80% of the primary studies were from HICs and described all levels of neurotrauma prevention. Only 65 papers came from LMICs, which mostly described primary prevention, focussing on road safety. For the reviews, 41 papers (66.1%) reviewed primary, 18 tertiary (29.1%), and three secondary preventative approaches. Most of the primary papers in the reviews came from HICs (67.7%) with 5 reviews on only LMIC papers. Fifteen reviews (24.1%) included papers from both HICs and LMICs. Intervention settings ranged from nationwide to community-based but were not reported in 44 papers (10.8%), most of which were reviews. Contextual factors were described in 62 papers and varied depending on the interventions. CONCLUSIONS: There is a large quantity of global evidence on strategies and interventions for neurotrauma and RTCs prevention. However, fewer papers were from LMICs, especially on secondary and tertiary prevention. More primary research needs to be done in these countries to determine what strategies and interventions exist and the applicability of HIC interventions in LMICs.

RESUMO

INTRODUCTION: Neurotrauma is an important global health problem. This 'silent epidemic' is a major cause of death and disability in adolescents and young adults, with significant societal and economic impacts. Globally, the largest cause of neurotrauma is road traffic collisions (RTCs). Neurotrauma and RTCs are largely preventable, and many preventative strategies and interventions have been established and implemented over the last decades, particularly in high-income countries. However, these approaches may not be applicable globally, due to variations in environment, resources, population, culture and infrastructure. This paper outlines the protocol for a scoping review, which seeks to map the evidence on strategies and interventions in neurotrauma and RTCs prevention globally, and to ascertain contextual factors that influence their implementation. METHODS AND ANALYSIS: This scoping review will use the established methodology by Arksey and O'Malley. Eligible studies will be identified from five electronic databases (MEDLINE, EMBASE, CINAHL, Global Health/EBSCO and Cochrane Database of Systematic Reviews) and grey literature sources. We will also carry out bibliographical and citation searching of included studies. A two-stage selection process, which involves screening of titles and abstracts, followed by full-text screening, will be used to determine eligible studies which will undergo data abstraction using a customised, piloted data extraction sheet. The extracted data will be presented using evidence mapping and a narrative summary. ETHICS AND DISSEMINATION: Ethical approval is not required for this scoping review, which is the first step in a multiphase public health research project on the global prevention of neurotrauma. The final review will be submitted for publication to a scientific journal, and results will be presented at appropriate conferences, workshops and meetings. Protocol registered on 5 April 2019 with Open Science Framework (https://osf.io/s4zk3/).

RESUMO

BACKGROUND: Hydatid cyst of the brain is serious zoonotic parasitic infections which have profound health consequences if left untreated. The surgical excisions of the cysts are rewarding for both the patient the neurosurgeon. METHODS: The study was conducted prospectively at Department of Neurosurgery Hayatabad Medical Complex Peshawar from January 2013 to December 2014. Patients with a diagnosis of intracranial hydatid cysts were included, clinical and radiological features recorded, intervention and postoperative outcome were analysed. RESULTS: Eleven patients with a male to female ratio of 1.7:1. Mean age was 12.4 (SD ± 6.5) years with median GCS on arrival of 10 (SD ± 2.5). Clinical features were headache (81.8%), vomiting (90.9%), seizures (36.4%), focal deficits (54.5%) and papilloedema (72.7%). The median GCS on discharge was 13 (SD ± 1.1) while GOS at 1 month follow up was 4 (SD ± 0.7). The bivariate analysis showed inverse correlation (R² = -0.68; p = 0.02) between duration of symptoms and outcome while GCS on admission was positively correlated (r(s) = 0.75; p = 0.007) with the outcome. There was no mortality. CONCLUSION: Despite its rarity the clinical features are non-specific while radiological features help in establishing diagnosis. Earlier diagnosis and prompt intervention is the key to favourable outcome.

RESUMO

BACKGROUND: Backache is a significant source of disability and suffering in our society. The treatment modalities need continued enhancement in order to achieve the desired goals of lowering morbidity and financial losses while improving the response of the patient. METHODS: This prospective comparative study was conducted at the department of Orthopaedics and Spine Surgery, Khyber Teaching Hospital Peshawar from July 2013 to June 2015. Two interventional groups were designated; Group 1 was comprised of 54 patients who were injected with epidural bupivacaine plus methylprednisolone while Group 2 included 55 patients who were injected with bupivacaine only. Outcome was assessed using the visual analogue scale and Oswestry disability index (ODI). RESULTS: Fifty-five female and 54 male patients with mean age 49.37 years±10.46 SD, Mean symptoms duration was 15.01 months±9.32 SD. Common presenting symptoms were backache (77.1%), lower limbs pain (66.1%), dermatomal paresthesias (54.1%) and neurogenic claudication in 57.8% patients. The mean visual analogue score (VAS) after injection was 3.18±1.29 while mean ODI after injection was 23.615. There was a statistically significant reduction in VAS scores (2-sided p=0.003, OR =4.03, 95% CI: 1.535-10.60) following the injection. CONCLUSIONS: An epidural spinal injection is a viable option for achieving relief of pain & improves functioning in individuals with radicular backache. However, further research is advised in order to clarify the role of ESI for long-term relief.
