AbstractIntroductionMaterials and methodsResultsConclusionGrowing skull fractures are a rare complication of paediatric skull fractures. Despite its rarity, a large proportion of resources go towards detecting this complication. This study aims to identify the factors associated with growing skull fracture development to determine which children require follow-up.This was a single-centre retrospective study examining the referral data from all patients under one years old referred with head trauma between 2013 and 2023 (n = 246). Of these patients 189 sustained skull fractures, with two requiring surgery for a growing skull fracture. Referral data for all head injuries between 2008 and 2013 was unavailable but surgical records were accessed for the only case of a child who developed a growing skull fracture in this time period. Each fracture was analysed using the commuted tomography (CT) head for its characteristics, including fracture splay distance and fracture elevation/depression.A total of 190 cases were reviewed, which showed a male to female ratio of 1.6:1. The majority of patients presented prior to one month of age and the most common mechanism of injury was a fall (80%). The most common fracture sustained was a linear fracture (87.4%). Of all fractures, the most common bone affected was the parietal bone (88.4%). Of those who developed a growing skull fracture, there was a significant difference in both the fracture splay distance (p < .05) and fracture elevation/depression distance (p < .05). All three patients who had growing skull fractures had a fracture splay distance above 5 mm at presentation and an elevation/depression of over 4 mm. 32% of children (n = 61) who had fractures had follow-up, with only nine having a fracture diastasis over 4mm.Resources and investigations should focus on children with fracture displacement over 4mm and/or elevation/depression distance of over 3mm, as they are at significantly greater risk of growing skull fracture development.

Purpose: To describe pneumatization and topographic position of the posterior clinoid process (PCP) in healthy children when approaching the anterior and middle fossae. Methods: The study consisted of computed tomography images of 180 pediatric patients (90 males / 90 females), aged 1–18 years. The presence or absence of PCP pneumatization was noted, and the distances of certain landmarks to PCP were measured. Results: The distances of the foramen ovale, foramen rotundum, superior orbital fissure, anterior clinoid process (ACP), foramen magnum and crista galli to PCP were measured as 18.59 ± 3.36 mm, 15.37 ± 3.45 mm, 14.60 ± 3.05 mm, 5.27 ± 3.24 mm, 32.03 ± 3.27 mm, and 30.45 ± 3.93 mm, respectively. These parameters increased with growth (between 1–18 years), but the distance between PCP and ACP decreased with an irregular pattern. In 11 sides (3.10%), a fusion between PCP and ACP was determined. PCP pneumatization was identified in 32 sides (8.9%). Its pneumatization correlated with pediatric ages (p < 0.001), but not gender (p = 0.459) or side (p = 0.711). Most of PCP pneumatization appeared after late childhood period (i.e., between 10–18 years). Conclusion: Our study provides beneficial data for neurosurgeons to use PCP as a reference point for creating a skull base map in children, because of the incomparable position of PCP in the skull base center.

Promoting the involvement of women in surgery, particularly in neurosurgery, is crucial in today's male-dominated landscape. Without proper recognition and encouragement, many talented and pioneering women may continue to be undervalued, despite their significant impact on the field. Gender inequality has been a persistent issue throughout history, with limited progress despite the increasing presence of women in the workforce. Historically, women were viewed as inferior to men, even within the medical profession, due to perceived physical differences. This perception was reinforced in religious texts, depicting women as bearing the consequences of the first woman's actions. However, it is important to recognize and support these talented women, allowing them to showcase their contributions in their respective fields. One notable figure in this regard is Maria Karampouga, the first female neurosurgeon graduate in Cyprus. Born in Alexandroupolis, Greece, Maria Karampouga began her medical training after passing a national examination and achieving excellence. After successfully completing her studies, attaining the top score in her graduating class she began a residency in general surgery and then neurosurgery in Greece. Seeking the best possible training, she left her studies incomplete and moved to Cyprus to restart her training in Neurosurgery. She was the first woman ever associated with Neurosurgery in Cyprus and in June 2023, she became the first woman to complete the country's residency program in Neurosurgery. Currently, she is a researcher at University of Pittsburg, Medical Center. [ABSTRACT FROM AUTHOR]

Background: The literature lacks a combined analysis of neurosurgical microvascular anastomosis training models. We performed a systematic literature search to provide an overview of the existing models and proposed a classification system based on the level of simulation and reproducibility of the microvascular anastomosis. Methods: The systematic literature search followed the PRISMA guidelines. We consulted MEDLINE, Web of Knowledge, and EMBASE independently for papers about bypass training models. Every training model was analyzed according to six tasks supposed to esteem their fidelity to the real operative setting by using a scoring system from zero to two. Finally, authors classified the models into five classes, from A to E, by summing the individual scores. Results: This study included 109 papers for analysis. Training models were grouped into synthetic tubes, ex vivo models (animal vessels, fresh human cadavers, human placentas) and in vivo simulators (live animals—rats, rabbits, pigs). By applying the proposed classification system, live animals and placentas obtained the highest scores, falling into class A (excellent simulators). Human cadavers and animal vessels (ex vivo) were categorized in class B (good simulators), followed by synthetic tubes (class C, reasonable simulators). Conclusions: The proposed classification system helps the neurosurgeon to analyze the available training models for microvascular anastomosis critically, and to choose the most appropriate one according to the skills they need to improve [ABSTRACT FROM AUTHOR]

Introduction: The goal of surgical management in pediatric low-grade gliomas (pLGGs) is gross total resection (GTR), as it is considered curative with favorable long-term outcomes. Achieving GTR can be challenging in the setting of eloquent-region gliomas, in which resection may increase risk of neurological deficits. Awake craniotomy (AC) with intraoperative neurofunctional mapping (IONM) offers a promising approach to achieve maximal resection while preserving neurological function. However, its adoption in pediatric cases has been hindered, and barriers to its adoption have not previously been elucidated. Findings: This review includes two complementary investigations. First, a survey study was conducted querying pediatric neurosurgeons on their perceived barriers to the procedure in children with pLGG. Next, these critical barriers were analyzed in the context of existing literature. These barriers included the lack of standardized IONM techniques for children, inadequate surgical and anesthesia experience, concerns regarding increased complication risks, doubts about children's ability to tolerate the procedure, and perceived non-indications due to alternative monitoring tools. Conclusion: Efforts to overcome these barriers include standardizing IONM protocols, refining anesthesia management, enhancing patient preparation strategies, and challenging entrenched beliefs about pediatric AC. Collaborative interdisciplinary efforts and further studies are needed to establish safety guidelines and broaden the application of AC, ultimately improving outcomes for children with pLGG.

Neurosurgeons may resort to caffeine, alcohol, and various drugs to maintain peak performance as they grapple with work demands and escalated stress. The prevalence of this controversial strategy remains largely unexplored. An anonymous survey of 23 questions formulated by our research group was distributed through personal contacts and neurosurgical societies. Inquiries revolved around the use of medications and other substances for job-related reasons. Data were analyzed via regression and descriptive statistics in python. In total, 215 neurosurgeons (43 residents) were included, with 213 disclosing their gender (94 females). Out of all, 9.3% were <30, 38.1% were 30–39, 44.6% were 40–59, and 7.9% were >60 years old. Most (70.7%) practiced in Europe, 18.6% in Asia, 6.5% in North and South America, and the rest in Africa or Australia. While 132 participants stated they consume caffeine to manage challenging schedules, drugs for cognitive and mood enhancement were utilized by 18 and 35 respectively. Alcohol was employed for stress relief by 28 with 4 reporting as heavy drinkers. Drugs posed a solution to sleep disorders for 82, and helped 8 others in strengthening their hand dexterity. Notably, 12 of those claiming drug use initiated it in medical school. Exercise, self-care activities, and relational support were the main alternatives sought. Ultimately, most responders recommended extending mental health assistance and raising awareness about drug use. Reflecting on our results on job-associated drug use by neurosurgeons, we propose the judicious use of pharmacological or nonpharmacological adjuncts, alongside the prioritization of neurosurgeons' well-being.

Over the last decade, simulation models have been increasingly applied as an adjunct for surgical training in neurosurgery. We aim through a practical course at a national neurosurgical conference to evaluate 3D non-cadaveric simulation models along with augmented reality for learning and practicing the pterional craniotomy approach among a wide variety of participants including medical students, neurosurgery residents, and attending neurosurgeons. Our course was conducted during an international neurosurgery meeting with 93 participants but the course surveys (pre- and post-course) were completed by 42 participants. Most participants were medical students (31; 73.8%). Participants with no experience (the majority) in cadaver lab dissections, craniotomy as first operator, and as second operator represented 12 (27.9%), 29 (69%), and 22 (52.4%), respectively. Participants with moderate experience in cadaver lab dissections were 23 (53.5%). Post-course survey respondents noted positive feedback in most items queried including enhancement of familiarity and acquiring skills, confidence with neurosurgery instruments, confidence with microscope, part of standard training, traditional training, and lifelong training. Simulation model combining augmented reality with physical simulation for hybrid experience can be a promising and valuable tool especially for medical students or early career neurosurgical residents.

We believe it is crucial to discuss the roles of women in medicine, specifically in surgery and neurosurgery. Despite society's progress toward gender equality in surgery and neurosurgery, these fields remain predominantly male. Recognizing and supporting these talented women allow them to bring attention to their contributions in their respective fields. Two notable French neurosurgeons, Françoise Lapierre, and Bernadette Stilhart, have played significant roles in their field for several decades. Françoise Lapierre, the second head of neurosurgery at Poitiers since its creation, was one of the first female heads of neurosurgery in France. In addition to her departmental role, she has also conducted training missions in the Far East, specifically in Vietnam and Cambodia. She also served as the Editor-in-Chief of the journal Neurochirurgie for several years. Bernadette Stilhart, with a career spanning almost 50 years, has trained multiple generations of neurosurgeons from France and around the world. She has also been the head of one of France's oldest neurosurgery departments in Colmar, Alsace for 20 years. [ABSTRACT FROM AUTHOR]

Neurosurgery is a field with complex ethical issues. In this article, we aim to provide an overview of key and emerging ethical issues in neurosurgery with a focus on issues relevant to practicing neurosurgeons. These issues include those of informed consent, capacity, clinical trials, emerging neurotechnology, innovation, equity and justice, and emerging bioethics areas including community engagement and organizational ethics. We argue that bioethics can help neurosurgeons think about and address these issues, and, in turn, the field of bioethics can benefit from engagement by neurosurgeons. Several ideas for increasing engagement in bioethics are proposed. [ABSTRACT FROM AUTHOR]

Sofia Ionescu (1920–2008) was the first female neurosurgeon in the world, pioneering her field with skill, dedication, and humility. Born in Romania, she began her career amid the tumult of World War II, performing her first neurosurgical procedure in 1944. Despite initial skepticism, her talent and commitment earned her recognition, culminating in her acknowledgment as the first female neurosurgeon by the World Federation of Neurosurgical Societies in 2005. Throughout her illustrious career, she mentored colleagues, contributed to scientific literature, and innovated surgical techniques, all while maintaining a compassionate and composed demeanor. Her legacy serves as a beacon of inspiration for neurosurgeons worldwide, reminding them of the importance of diligence, empathy, and unwavering dedication to patient care. Even in retirement, her influence endures, as she continues to be revered for her remarkable contributions to the field of neurosurgery. We searched Google, PubMed, and others about Sofia Ionescu and compiled the data about her. We got very important information about her and compiled together for this article. Sofia Ionescu is regarded as the first female neurosurgeon of the world and she paved the way and encouraged many young female neurosurgeons in the field. [ABSTRACT FROM AUTHOR]

Background: Neurosurgery demands exceptional precision due to the brain's complex and delicate structures, necessitating precise targeting of pathological targets. Achieving optimal outcomes depends on the surgeon's ability to accurately differentiate between healthy and pathological tissues during operations. Raman spectroscopy (RS) has emerged as a promising innovation, offering real-time, in vivo non-invasive biochemical tissue characterization. This literature review evaluates the current research on RS applications in intraoperative neurosurgery, emphasizing its potential to enhance surgical precision and patient outcomes. Methods: Following PRISMA guidelines, a comprehensive systematic review was conducted using PubMed to extract relevant peer-reviewed articles. The inclusion criteria focused on original research discussing real-time RS applications with human tissue samples in or near the operating room, excluding retrospective studies, reviews, non-human research, and other non-relevant publications. Results: Our findings demonstrate that RS significantly improves tumor margin delineation, with handheld devices achieving high sensitivity and specificity. Stimulated Raman Histology (SRH) provides rapid, high-resolution tissue images comparable to traditional histopathology but with reduced time to diagnosis. Additionally, RS shows promise in identifying tumor types and grades, aiding precise surgical decision-making. RS techniques have been particularly beneficial in enhancing the accuracy of glioma surgeries, where distinguishing between tumor and healthy tissue is critical. By providing real-time molecular data, RS aids neurosurgeons in maximizing the extent of resection (EOR) while minimizing damage to normal brain tissue, potentially improving patient outcomes and reducing recurrence rates. Conclusions: This review underscores the transformative potential of RS in neurosurgery, advocating for continued innovation and research to fully realize its benefits. Despite its substantial potential, further research is needed to validate RS's clinical utility and cost-effectiveness. [ABSTRACT FROM AUTHOR]

Background: Detection and localization of cerebral microbleeds (CMBs) is crucial for disease diagnosis and treatment planning. However, CMB detection is labor-intensive, time-consuming, and challenging owing to its visual similarity to mimics. This study aimed to validate the performance of a three-dimensional (3D) deep learning model that not only detects CMBs but also identifies their anatomic location in real-world settings. Methods: A total of 21 patients with 116 CMBs and 12 without CMBs were visited in the neurosurgery outpatient department between January 2023 and October 2023. Three readers, including a board-certified neuroradiologist (reader 1), a resident in radiology (reader 2), and a neurosurgeon (reader 3) independently reviewed SWIs of 33 patients to detect CMBs and categorized their locations into lobar, deep, and infratentorial regions without any AI assistance. After a one-month washout period, the same datasets were redistributed randomly, and readers reviewed them again with the assistance of the 3D deep learning model. A comparison of the diagnostic performance between readers with and without AI assistance was performed. Results: All readers with an AI assistant (reader 1:0.991 [0.930–0.999], reader 2:0.922 [0.881–0.905], and reader 3:0.966 [0.928–0.984]) tended to have higher sensitivity per lesion than readers only (reader 1:0.905 [0.849–0.942], reader 2:0.621 [0.541–0.694], and reader 3:0.871 [0.759–0.935], p = 0.132, 0.017, and 0.227, respectively). In particular, radiology residents (reader 2) showed a statistically significant increase in sensitivity per lesion when using AI. There was no statistically significant difference in the number of FPs per patient for all readers with AI assistant (reader 1: 0.394 [0.152–1.021], reader 2: 0.727 [0.334–1.582], reader 3: 0.182 [0.077–0.429]) and reader only (reader 1: 0.364 [0.159–0.831], reader 2: 0.576 [0.240–1.382], reader 3: 0.121 [0.038–0.383], p = 0.853, 0.251, and 0.157, respectively). Our model accurately categorized the anatomical location of all CMBs. Conclusions: Our model demonstrated promising potential for the detection and anatomical localization of CMBs, although further research with a larger and more diverse population is necessary to establish clinical utility in real-world settings.

Background: Medial sphenoid wing meningiomas are best treated through pterional craniotomy, as pterional craniotomy provides wide and multidirectional exposure of the anterior and middle cranial fossa. Anterior clinoidectomy can increase the exposure potential. To delineate the role of anterior clinoidectomy (AC) in the standard pterional craniotomy approach through the evaluation of operability score measures (manoeuvrability arc, depth of surgical field, and surgical angle of attack). All patients with inner sphenoidal wing meningioma who underwent microsurgical excision between February 2022 and October 2023 were enrolled in the study. Preoperative and postoperative imaging studies (MR contrast studies and 3D thin-slice CT scans of the brain) were performed to determine the tumour size, extent, and pattern of optic canal involvement by comparing pre- and postoperative operability score parameters. Results: Twenty-five patients met our inclusion criteria: 2 males (8%) and 23 females (92%). The mean age (SD) was 49.08 ± 6.42 years, with an age range of 39–60 years. The preoperative visual manifestations were as follows: eight patients (32%) had mild visual impairment, five patients (20%) had moderate visual impairment, six patients (24%) had severe visual impairment, and five patients (20%) had blindness. There was a significant positive correlation between the operability score and extent of resection (gross total resection was correlated with a higher operability score) (r = 0.301, n = 25, p = 0.005). Conclusions: A well-planned manoeuvrable arc allows neurosurgeons to perform surgery with precision, ultimately impacting surgical outcomes and the potential for complete tumour removal with minimal patient morbidity.

Stress in surgeons is well-known for its negative impact on neurocognition and surgical performance. Surgeons commonly use music for stress reduction, but its specific effects on neurosurgeons remain unclear. This study aims to investigate how listening to music during microsurgery affects neurocognitive (NC) functions, subjective anxiety, and stress levels in neurosurgeons. Conducted in 2 phases, the pilot phase involved 23 neurosurgeons completing a survey and rating compositions based on ragas of North Indian/Hindustani classical music for suitability during surgery. Five excerpts were selected for the main phase, which involved 3 neurosurgeons performing 16 surgeries, 8 with and 8 without music. Data collection included presurgery assessments of sleep, caffeine intake, subjective stress levels, perceived complexity of the surgery that was to be performed, and NC tasks. Postsurgery subjective stress levels, actual complexity, and surgeon experiences with music were recorded. While there was a trend toward reduced stress and perceived complexity with music, statistical significance was not reached. NC tasks showed nonsignificant improvement with music, with a significant (at P < 0.001) speed-accuracy trade-off noted in response inhibition. Music appears to reduce subjective stress and task complexity, influencing neurocognition, particularly through speed-accuracy trade-offs. Further research is needed to understand its mechanisms and appropriate contexts for use before widespread recommendation. [ABSTRACT FROM AUTHOR]

Elective lumbar fusions have received criticism for inappropriate utilization. Here, we use a novel Operative Value Index (OVI) to assess whether "indicated," evidence-based lumbar fusions are associated with increased value (outcomes per dollar spent). This study is a retrospective analysis of a prospective observational cohort of 294 patients undergoing elective lumbar fusions at a single large academic institution. All patients were preoperatively evaluated by a panel of neurosurgeons for concordance with evidence-based medicine (EBM), determined through guidelines from the North American Spine Society. Oswestry Disability Index (ODI) scores were collected for all patients both preoperatively and at 6-months postoperatively. Time-driven activity-based costing was employed to determine both direct and indirect intraoperative costs. The OVI was defined as the percent improvement in ODI per $1000 spent intraoperatively. Generalized linear mixed model regression, adjusting for confounders, was performed to assess whether EBM-concordant surgeries were associated with higher OVI. Of 294 elective lumbar fusions, 92.9% (n = 273) were EBM-concordant. The average total cost of an EBM-concordant lumbar fusion was $17,932 (supplies: $13,020; personnel: $4314), compared to $20,616 (supplies: $15,467; personnel: $4758) for an EBM-discordant fusion. Average OVI was 2.27 for a concordant fusion, compared to 0.11 for a discordant fusion. Generalized linear mixed model analysis revealed that EBM-concordant cases were associated with significantly higher OVI (β-coefficient 2.0, P < 0.001). EBM-concordant fusions were associated with 2% greater improvement in ODI scores from baseline for every $1000 spent intraoperatively. Systematic methods for increasing guideline adherence for lumbar fusions could therefore improve value at scale. [ABSTRACT FROM AUTHOR]

It is important to have a diverse workforce in clinical and research environments. A cross-sectional study was conducted to examine the possible presence of gender, perceived skin color, education, academic productivity, and career progression inequalities among neurosurgeons in the United Kingdom. A list of all consultant neurosurgeons working in the United Kingdom (N = 384) was obtained from the Specialist Info website. Data about their education, research activity, academic productivity, impact, and progression were obtained from publicly available online sources. Over 90% of consultants and all full professors were men. There was a small number of black or brown consultant neurosurgeons and no black full professors. Very few black or brown consultants obtained their medical degree from a top university or had a PhD. There were no gender disparities in currently being affiliated with a university (or top university), obtaining a PhD or Master's degree, ranking of the university from which they obtained their medical degree, Master's degree or PhD, or number of pages and open access availability of their PhD thesis. Neurosurgeons who obtained their medical degree from the UK and those with a PhD had more publications, citations and a higher h-index. Male (vs. female) academic neurosurgeons had more publications, nonself-citations, and a higher h-index, and white (vs. brown) female neurosurgeons had more citations per paper. This study identified important gender, skin color, education, academic productivity, and career progression inequalities in the 2023 UK consultant neurosurgery workforce. [ABSTRACT FROM AUTHOR]

Endoscopic endonasal transsphenoidal surgery (EETS) is a common treatment for sellar and suprasellar tumors. While endoscopic training has improved over the years and formal fellowship training is now broadly available, the operative nuances of EETS conjectures the existence a learning curve as a neurosurgeon matures with experience. We aim to evaluate operative outcomes of 3 different experience levels of neurosurgeons over time at a single institution. We reviewed all adult patients who underwent EETS at Loyola University Medical Center by 3 early career, 1 midcareer, and 2 late career neurosurgeons from 2007 to 2023. A comparative assessment of patient demographics, tumor features, and surgical outcomes was done using metrics such as length of surgery, rates of gross total resection (GTR) and symptomatic improvement, new postoperative steroid dependence, and development of diabetes insipidus (DI). T-tests and χ2 were used to statistically evaluate the study cohorts. A total of 297 patients underwent EETS. One hundred three (35%) were operated on by an early career, 122 (41%) by a mid-career, and 72 (24%) by a late career neurosurgeon. Late-career surgeons had shorter operation times (144 vs. 180 minutes with early and mid-career, P = 0.029) and increased GTR rates (P = 0.008). There were no significant differences between the symptomatic improvement rates amongst various surgeon experience levels. Although not statistically significant, early-career neurosurgeons had lower rates of new postoperative steroid dependence. Patients of early career surgeons experienced significantly less DI (15% vs. 40%, P = 0.004). Late-career neurosurgeons had shorter operation lengths, achieved higher rates of GTR, and their patients experienced significantly higher rates of DI. Overall outcomes remained stable throughout the course of 16 years between different surgeon experience levels. [ABSTRACT FROM AUTHOR]

South Asia, consisting of Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka, spreads between the Himalayan base and the Indian Ocean and shares identical geophysical characteristics. With the inclusion of its newest member Afghanistan, these 8 member nations of the South Asian Association for Regional Cooperation (SAARC) share more or less a homogenous geographical, political, and historical background and cultural heritage, with a significant role in shaping the world. This densely populated area is home to around a quarter of the world's total population. From the ancient ages, the neurosurgical practice has paced relentlessly and in the last 100 years, it has reached its zenith. With modern advancements, neurosurgery has developed in its diagnostic and treatment modalities along with facilities for training and education. Despite falling behind owing to economic, educational, and geopolitical constraints, the pioneers of the SAARC region have established the fields of neurosurgery in their respective countries with command. No constraint could stop them from educating and training young physicians to make competent neurosurgeons to evolve the field of neurosurgery in their countries. Their firm determination and hard work paved the way to keep this field striving and thriving, to serve a substantial volume of the world population with their neurosurgical insight and skill. However, this region needs to go a long way as the number of neurosurgeons and facilities is still insufficient. This can be achieved with the guidance and collaboration among the neurosurgeons of the SAARC region as the youth here are talented and hardworking. [ABSTRACT FROM AUTHOR]

This study aims to evaluate the adherence to surgical antibiotic prophylaxis (SAP) guidelines in elective neurosurgery and assess the impact on surgical site infection (SSI) rates in a tertiary teaching hospital in Malaysia. A retrospective review was conducted on patients who underwent elective neurosurgical procedures from January 1, 2021, to December 31, 2021, in a 1600-bed tertiary teaching hospital. The study assessed adherence to national and hospital SAP guidelines, focusing on the choice of antibiotic, dosage, timing, and duration. Additionally, a survey was conducted among neurosurgeons to evaluate their knowledge, attitudes, and practices regarding SAP. Out of 202 patients included, there was a 99% compliance rate with antibiotic choice and 69.8% with the antibiotic duration. The SSI rate was identified at 6.4%. The knowledge, attitudes, and practices survey highlighted a strong awareness of SAP guidelines among surgeons, albeit with variations in practice, particularly in antibiotic duration and choice of antibiotics. While there is high adherence to the correct choice of antibiotic for SAP in elective neurosurgery, there are gaps in compliance with the recommended duration of antibiotic use. The study highlights the need for targeted interventions to improve adherence to SAP guidelines, which could potentially reduce the incidence of SSI in neurosurgery. Ongoing education and auditing are essential to optimize SAP practices and enhance patient outcomes in neurosurgery. [ABSTRACT FROM AUTHOR]

Neurosurgical services and educational processes in Sudan have been severely disrupted by the ongoing armed conflict. The destruction of neurosurgical infrastructure and the continuous exodus of trained neurosurgeons from an already strained system have intensified the humanitarian crisis. The situation is further compounded by several factors, including attacks on medical professionals, partial suspension of neurosurgical training program, loss of communication tools, shortages of essential instruments, and disruptions in partnerships with regional and international neurosurgical associations. The re-establishment of international partnerships and the reconstruction of damaged neurosurgical infrastructure are advocated, coupled with the utilization of advanced research to address these critical issues. A staged recovery strategy is called for, and support from the global neurosurgical community is urged, highlighting the crucial role of academic platforms like "World Neurosurgery" in fostering global collaboration and disseminating research from conflict-affected regions.

Neurosurgeons demonstrate some of the highest levels of burnout among surgeons, yet little research has been done to understand the underlying stressors that neurosurgeons and trainees experience and the emotional responses to them. Our goal was to conduct a feasibility study identifying job stressors and emotional responses among neurosurgeons rather than generalize findings across the profession. Emphasizing a qualitative approach in this feasibility and descriptive study, we strategically selected a small sample of neurosurgical attendings, residents, and fellows at 2 United States academic neurosurgical departments to ensure an in-depth analysis laying the groundwork for future extensive research. Participants were asked to complete a questionnaire regarding work-related stressors and high- and low-arousal emotional responses to these stressors, as well as a standardized Depression, Anxiety, and Stress Scale. Both quantitative and qualitative analyses evaluating types of stressors and emotional responses reported were assessed based on participant training level. Participants identified 3 main stressors: 1) administrative deficiencies; 2) delivering bad news/saving lives; and 3) work-life balance. A low frequency of negative emotional responses was reported, but those reported were mainly high-arousal emotions. Limited prior training in coping strategies was also reported. We also found that residents, fellows, and faculty surgeons reported about work stressors and coping strategies differently. The results of our study provide an understanding of neurosurgical professionals' unique emotional landscape, emphasizing the need for reforms in administrative practices, enhanced, healthy coping strategies, and career stage-specific mental health support.

Historical data and a partial description of the ongoing neurosurgical scenario in Nepal were reported and published earlier. However, updated data on neurosurgical manpower in Nepal has not yet been published. This study aims to explore the neurosurgical workforce in Nepal involved in different administrative territories and in different health sectors. This is a cross-sectional descriptive study. A nationwide survey was conducted through personal communication from April to September of 2023. Data on neurosurgeons in all 7 provinces of the country and the major sectors of the health services were collected. Similarly, the number of neurosurgeons in the country every year from 1988 was also collected. Through September 2023, there are 114 actively practicing neurosurgeons in the country for the population of 29,164,578, meaning 1 neurosurgeon serving about 255,829 people. Neurosurgeons are available in all 7 provinces of the country. More than half of the neurosurgeons in the country are fully involved in private practice while about one-third are in medical college and less than one-fifth are in the government service. The capital city has more than half of the neurosurgeons of the country. The number of neurosurgeons in the country is still small, however its ratio with population is better than most of the other South Asian countries. In a short period of time, neurosurgical service flourished significantly in Nepal and is available in all the provinces and thus it has become more easily accessible. [ABSTRACT FROM AUTHOR]

Nigeria's neurosurgical field faces profound challenges, including a critically low neurosurgeon-to-patient ratio and significant migration of medical professionals to developed countries. High costs, low socioeconomic status, and the urban-centric location of neurosurgical centers impede access to care. Key barriers to service delivery include lack of manpower, insufficient emergency care, limited imaging modalities, inadequate operative equipment, and ineffective political and administrative policies. Neurotrauma is the primary reason for neurosurgical intervention but is poorly managed due to delayed access and insufficient guidelines. The neurosurgical education system is strained by limited training capacity and the absence of subspecializations, restricting specialized care. Research output is low, hindered by limited infrastructure, lack of databases, insufficient funding, and minimal international collaboration. To address these issues, it is critical to enhance the imaging capabilities, ensure the availability of operative equipment, and establish effective policies for task sharing and communication at different levels of care. Other approaches include expanding training capacity, particularly in rural areas, implementing a uniform match system for residency, addressing gender disparities, and utilizing dual practice to ensure adequate compensation for neurosurgeons. Furthermore, stakeholders should develop subspecialization programs in areas such as neurovascular, neuro-oncology, pediatric neurosurgery, and minimally invasive neurosurgery to expand service scope. To transform the neurosurgical research landscape, efforts should be made to establish electronic medical databases, foster international collaborations to ensure funding, and make research mandatory for accreditation renewal to ensure continuous academic contribution.

Introduction The main goal of this study was to assess the feasibility of a head-mounted display (HMD) providing telemedicine neurosurgical support during a decompressive craniectomy by a military surgeon who is isolated from readily available neurosurgical care. The secondary aim was to assess the usability perceived by the military surgeon and to evaluate technical aspects of the head-mounted display. Materials and Methods After a standard concise lecture, 10 military surgeons performed a decompressive craniectomy on a AnubiFiX-embalmed post-mortem human head. Seven military surgeons used a HMD to receive telemedicine neurosurgical support. In the control group, three military surgeons performed a decompressive craniectomy without guidance. The performance of the decompressive craniectomy was evaluated qualitatively by the supervising neurosurgeon and quantified with the surgeons' operative performance tool. The military surgeons rated the usability of the HMD with the telehealth usability questionnaire. Results All military surgeons performed a decompressive craniectomy adequately directly after a standard concise lecture. The HMD was used to discuss potential errors and reconfirmed essential steps. The military surgeons were very satisfied with the HMD providing telemedicine neurosurgical support. Military surgeons in the control group were faster. The HMD showed no hard technical errors. Conclusions It is feasible to provide telemedicine neurosurgical support with a HMD during a decompressive craniectomy performed by a non-neurosurgically trained military surgeon. All military surgeons showed competence in performing a decompressive craniectomy after receiving a standardized concise lecture. The use of a HMD clearly demonstrated the potential to improve the quality of these neurosurgical procedures performed by military surgeons. [ABSTRACT FROM AUTHOR]

Background and Aims: While the number of female physicians has increased since the 1970s, there continues to be a lack of female surgeons compared to their male counterparts, with the gender gap more prominent in surgical subspecialties such as neurosurgery. While surgical subspecialities have accelerated initiatives to close the gap, potential disparities in research opportunities may position women at a disadvantage, particularly in neurosurgery, where academic publications are an indicator of residency match success. In this paper, we sought to investigate whether gender disparities exist in preresidency neurosurgery publications among current neurosurgery residents. Methods: The present study selected residency programs from the top 25 neurology and neurosurgery hospitals in US News & World Report's 2022 Ranking. A database of neurosurgery residents and their publications was created using PubMed, neurosurgery residency program websites, and supplementary search. Articles published between the time of birth and December 31st of the year of graduation (medical degree) were used to determine publications before residency. Results: Our research indicates that 25.7% (n = 135/526) of US neurosurgery residents at top 25 hospitals are women and 74.3% (n = 391/526) are men. Men (n = 391) had a median of 7 (interquartile range [IQR], 3–14.5; range, 0–129) publications before residency, and women (n = 135) had a median of 7 (IQR, 4–11.0; range, 0–74) publications before residency. There were no significant differences in the median number of publications between genders (p = 0.65). Conclusion: In conclusion, our research indicates there is no gender disparity in preresidency publications among neurosurgery residents. To improve women's representation in the field, further study is needed to better understand gender inequality among neurosurgeons, particularly in the earlier stages of medical training.

The Department of Neurosurgery at Aberdeen Royal Infirmary (ARI) marked its 75th anniversary in 2023. The unit began on 1 April 1948 when Mr W Martin Nichols became the first full-time neurosurgeon in the North of Scotland. Prior to World War II (WWII), there were only a handful of surgeons dedicated to the specialty in the UK. Martin Nichols was one of a new wave of pioneering surgeons who had sought out experience in this fledgling field and went on to establish post-war units in teaching hospitals across the country. Like others of his generation, the war had an enormous effect on his career. Here we discuss his early formative career gaining experience in the leading centres of the day, WWII and his 5 years as a prisoner of war, going on to set up the new unit in Aberdeen. We are fortunate to have had access to many of Nichols' letters and other materials that provide valuable insights into the period. [ABSTRACT FROM AUTHOR]

Management of patients with glioblastoma (GBM) is complex and involves implementing standard therapies including resection, radiation therapy, and chemotherapy, as well as novel immunotherapies and targeted small-molecule inhibitors through clinical trials and precision medicine approaches. As treatments have advanced, the radiological and clinical assessment of patients with GBM has become even more challenging and nuanced. Advances in spatial resolution and both anatomical and physiological information that can be derived from MRI have greatly improved the noninvasive assessment of GBM before, during, and after therapy. Identification of pseudoprogression (PsP), defined as changes concerning for tumor progression that are, in fact, transient and related to treatment response, is critical for successful patient management. These temporary changes can produce new clinical symptoms due to mass effect and edema. Differentiating this entity from true tumor progression is a major decision point in the patients management and prognosis. Providers may choose to start an alternative therapy, transition to a clinical trial, consider repeat resection, or continue with the current therapy in hopes of resolution. In this review, the authors describe the invasive and noninvasive techniques neurosurgeons need to be aware of to identify PsP and facilitate surgical decision-making.

Aims: People with severe, persistent low back pain (LBP) may be offered lumbar spine fusion surgery if they have had insufficient benefit from recommended non-surgical treatments. However, National Institute for Health and Care Excellence (NICE) 2016 guidelines recommended not offering spinal fusion surgery for adults with LBP, except as part of a randomized clinical trial. This survey aims to describe UK clinicians’ views about the suitability of patients for such a future trial, along with their views regarding equipoise for randomizing patients in a future clinical trial comparing lumbar spine fusion surgery to best conservative care (BCC; the FORENSIC-UK trial). Methods: An online cross-sectional survey was piloted by the multidisciplinary research team, then shared with clinical professional groups in the UK who are involved in the management of adults with severe, persistent LBP. The survey had seven sections that covered the demographic details of the clinician, five hypothetical case vignettes of patients with varying presentations, a series of questions regarding the preferred management, and whether or not each clinician would be willing to recruit the example patients into future clinical trials. Results: There were 72 respondents, with a response rate of 9.0%. They comprised 39 orthopaedic spine surgeons, 17 neurosurgeons, one pain specialist, and 15 allied health professionals. Most respondents (n = 61,84.7%) chose conservative care as their first-choice management option for all five case vignettes. Over 50% of respondents reported willingness to randomize three of the five cases to either surgery or BCC, indicating a willingness to participate in the future randomized trial. From the respondents, transforaminal interbody fusion was the preferred approach for spinal fusion (n = 19, 36.4%), and the preferred method of BCC was a combined programme of physical and psychological therapy (n = 35, 48.5%). Conclusion: This survey demonstrates that there is uncertainty about the role of lumbar spine fusion surgery and BCC for a range of example patients with severe, persistent LBP in the UK.

This review systematically examines the recent research from the past decade on diverse path-planning algorithms tailored for stereotactic neurosurgery applications. Our comprehensive investigation involved a thorough search of scholarly papers from Google Scholar, PubMed, IEEE Xplore, and Scopus, utilizing stringent inclusion and exclusion criteria. The screening and selection process was meticulously conducted by a multidisciplinary team comprising three medical students, robotic experts with specialized knowledge in path-planning techniques and medical robotics, and a board-certified neurosurgeon. Each selected paper was reviewed in detail, and the findings were synthesized and reported in this review. The paper is organized around three different types of intervention tools: straight needles, steerable needles, and concentric tube robots. We provide an in-depth analysis of various path-planning algorithms applicable to both single and multi-target scenarios. Multi-target planning techniques are only discussed for straight tools as there is no published work on multi-target planning for steerable needles and concentric tube robots. Additionally, we discuss the imaging modalities employed, the critical anatomical structures considered during path planning, and the current status of research regarding its translation to clinical human studies. To the best of our knowledge and as a conclusion from this systematic review, this is the first review paper published in the last decade that reports various path-planning techniques for different types of tools for minimally invasive neurosurgical applications. Furthermore, this review outlines future trends and identifies existing technology gaps within the field. By highlighting these aspects, we aim to provide a comprehensive overview that can guide future research and development in path planning for stereotactic neurosurgery, ultimately contributing to the advancement of safer and more effective neurosurgical procedures.

Neurosurgeons often use radiation to visualize blood vessels and implants intraoperatively. However, high exposure to radiation increases one's cancer risk. This study aims to investigate intraoperative ionizing radiation exposure awareness and associated morbidity among neurosurgeons. An anonymized 30-question survey about their intraoperative radiation exposure, protective measures, radiation knowledge, and any conditions that can arise from protracted radiation exposure was disseminated to 3344 American Association of Neurological Surgeons members. A total of 227 (6.8%) neurosurgeons completed the survey. Most neurosurgeons (61, 27%) performed 2–4 surgeries per week necessitating radiation (61, 27%), did not use a dosimeter (134, 59%), and wore a lead apron (89%) and a thyroid shield (75%). Only 7 (3%) of respondents could correctly identify the safety limit for occupational radiation. One hundred and thirty-four (59%) respondents correctly identified the relationship between distance and radiation dose reduction. Two hundred and thirteen (94%) neurosurgeons reported concern about occupational radiation exposure. No significant association was found between occupational radiation exposure and the rate of cataracts, combined cancer, and skin cancer. Multivariate logistic regression adjusting for age and cancer history found that the likelihood of developing leukemia (P = 0.02) and nonmalignant thyroid nodular disease (P = 0.01) is positively associated with increased total occupational radiation exposure. There is a need for improved radiation safety awareness among neurosurgeons, especially in the context of rising usage of minimally invasive surgery. This can allow for a greater understanding of radiation-associated risks among neurosurgeons and guide the implementation of safer practices. [ABSTRACT FROM AUTHOR]

Medical students often face challenges in choosing a career path due to limited exposure to specialized fields like neurosurgery. Understanding their perceptions and experiences is crucial in addressing the gaps in neurosurgical education and inspiring future neurosurgeons. A cross-sectional study was conducted involving 461 medical students, utilizing convenience sampling. Data collection employed a validated, self-administered tool. Statistical analysis in SPSS Version 25 included t-tests and chi-square tests, comparing scores based on age, gender, year of study, and exposure to the formal neurosurgical rotations in their institute. Significance value was set at P < 0.05. In the study of 461 medical students, 79.8% identified with the 19–23 age group, and 63.8% affirmed neurosurgery exposure. Medical students' perceptions included: 167 (36.3%) students found neurosurgery teaching sufficient; 164 (35.6%) disagreed that obtaining neurosurgical history is difficult; 224 (48.6%) agreed on neurosurgical disease complexity; and 250 (54.2%) found these diseases challenging and interesting. A majority of 183 (39.7%) respondents agreed that neurosurgical diseases had poor outcomes. Regarding training for neurosurgical surgery, 205 (44.5%) participants strongly agreed on its length, and 215 (46.7%) consented to extensive operating hours. However, 167 (36.3%) strongly disagreed about the ample job prospects in Pakistan. Enhancing neurosurgery education with quality, consistency, and adaptability is essential to bridge gaps and inspire future neurosurgeons. These findings guide improvements in educational programs, preparing a skilled workforce to meet evolving health-care demands. [ABSTRACT FROM AUTHOR]

Horseback riding can cause severe brain and spinal injuries. This study aimed to identify the spectrum of neurosurgical injuries related to recreational horseback riding. A retrospective study was performed utilizing the University of Puerto Rico neurosurgery database to identify patients who were consulted to the neurosurgery service between 2018 and 2023 after a horse fall during recreational activities. The outcome upon discharge using the modified Rankin scale (mRS) was documented. Descriptive statistics were used to report frequency and median values. The neurosurgery service evaluated and managed 112 patients with a horseback riding fall-related injury during 6 years. Ninety-eight (87.5%) patients were male. The patients' median age was 31.5 (IQR 22–40). There were 89 head injuries (79.5%), 19 spinal injuries (17%), and 4 combined head/spine injuries (3.5%). Forty percent of the patients were admitted to inpatient care with a median length of stay of 7 days (IQR 3–17). Twenty-four patients (21%) required surgery. Upon discharge, 86.6% of the patients had an mRS grade of 0–2, 3.6% had a grade of 3, 1.8% had a grade of 4, and 1.8% had a grade of 5. Seven patients (6%) died (mRS grade 6). Most neurologic injuries involve isolated trauma to the head. Fifteen percent of the riders' falls were caused after the horse was impacted by a motor vehicle. Forty percent of the patients require admission and 21% undergo surgery. Ten percent of the patients had a poor mRS grade of 4– to 6 when discharged. [ABSTRACT FROM AUTHOR]

It is crucial to promote the role of women in surgery, particularly in the field of neurosurgery, which is still predominantly male-dominated. Without recognition and support, these talented and pioneering women may continue to be overlooked, despite their significant contributions to the field. One such remarkable woman is Professor Aimée Redondo, the first female neurosurgeon professor in France. She was born in 1944 during the last years of World War II to immigrant parents from Spain. Thanks to grants and scholarships from the French government, Aimée Redondo was able to continue her education. She excelled in high school and even passed the entrance exam for medical school on her first attempt – a rare achievement at the time. In 1975, at the young age of 31, she became the first female professor of neurosurgery in France. After completing her residency, she worked as a senior neurosurgeon at the Salpêtrière Hospital in Paris and then joined the newly established department of neurosurgery at Beaujon Hospital. For over thirty years, she was a crucial member of this department and served as its head from 2004 until her retirement. Sadly, she passed away in 2022 at the age of 78. [ABSTRACT FROM AUTHOR]

Most of the scientific and healthcare resources in Mexico are limited to the large major cities. However, many communities with complex socioeconomic and cultural backgrounds have limited access to neurosurgical care. A cross-sectional study aiming to evaluate the population's perception regarding neurosurgical care was conducted. A nationwide online survey, conducted starting February 2023, assessed public perception of neurosurgical care. Data analysis was performed based on sociodemographic characteristics such as age, socioeconomic status, religion, and education. Pearson's chi-square and odds ratio were employed for statistical comparisons of categorical variables. A total of 508 participants consented to the survey. Younger participants and higher education levels correlated with greater perceived knowledge about neurosurgery (P = <0.001) and higher confidence in neurosurgical healthcare personnel (P = 0.021 and P = 0.022, respectively). Lower educational levels were prone to perceive neurosurgical care as less safe and effective (P = 0.002) and preferred to seek initial alternative/traditional treatments for neurosurgical issues (P = 0.012). A higher income level was associated with a preference for private healthcare over public services P = <0.001). Odds ratio analysis corroborated these findings. Healthcare personnel emerged as the most common source of information for neurosurgical diseases (71.4%). Our findings suggest that sociodemographic factors such as age, education, and income correlate with the population's self-perceived knowledge, trust and beliefs about safety and effectiveness regarding neurosurgical care in Mexico. These findings can be instrumental for developing healthcare policies that address the needs of Mexico's patient population. [ABSTRACT FROM AUTHOR]

Objective - Addressing the challenges that come with identifying and delineating brain tumours in intraoperative ultrasound. Our goal is to both qualitatively and quantitatively assess the interobserver variation, amongst experienced neuro-oncological intraoperative ultrasound users (neurosurgeons and neuroradiologists), in detecting and segmenting brain tumours on ultrasound. We then propose that, due to the inherent challenges of this task, annotation by localisation of the entire tumour mass with a bounding box could serve as an ancillary solution to segmentation for clinical training, encompassing margin uncertainty and the curation of large datasets. Methods - 30 ultrasound images of brain lesions in 30 patients were annotated by 4 annotators - 1 neuroradiologist and 3 neurosurgeons. The annotation variation of the 3 neurosurgeons was first measured, and then the annotations of each neurosurgeon were individually compared to the neuroradiologist's, which served as a reference standard as their segmentations were further refined by cross-reference to the preoperative magnetic resonance imaging (MRI). The following statistical metrics were used: Intersection Over Union (IoU), Sørensen-Dice Similarity Coefficient (DSC) and Hausdorff Distance (HD). These annotations were then converted into bounding boxes for the same evaluation. Results - There was a moderate level of interobserver variance between the neurosurgeons [ I o U : 0.789 , D S C : 0.876 , H D : 103.227 ] and a larger level of variance when compared against the MRI-informed reference standard annotations by the neuroradiologist, mean across annotators [ I o U : 0.723 , D S C : 0.813 , H D : 115.675 ] . After converting the segments to bounding boxes, all metrics improve, most significantly, the interquartile range drops by [ I o U : 37 % , D S C : 41 % , H D : 54 % ] . Conclusion - This study highlights the current challenges with detecting and defining tumour boundaries in neuro-oncological intraoperative brain ultrasound. We then show that bounding box annotation could serve as a useful complementary approach for both clinical and technical reasons. [ABSTRACT FROM AUTHOR]

Objective: 30-day readmissions are a significant burden on the healthcare system. Postoperative transitional care protocols (TCPs) for safe and efficient discharge planning are being more widely adopted to reduce readmission rates. Currently, little evidence exists to justify the utility of TCPs for improving patient outcomes in elective neurosurgery. The objective of this systematic review was to determine the extent to which TCPs reduce adverse outcomes in patients undergoing elective neurosurgical procedures. Materials and Methods: A systematic review and meta-analysis was conducted after PROSPERO registration. Pubmed, Embase, and Cochrane review databases were searched through February 1, 2024. Keywords included: "transitional care AND neurosurgery", "Discharge planning AND neurosurgery". Articles were included if they assessed postoperative TCPs in an adult population undergoing elective neurosurgeries. Exclusion criteria were pediatric patients, implementation of Enhanced Recovery After Surgery (ERAS) protocols, or non-elective neurosurgical procedures. The primary outcome was readmission rates after implementation of TCPs. Results: 16 articles were included in this review. 2 articles found that patients treated with TCPs had significantly higher chances of home discharge. 7 articles found a significant association between implementation of TCP and reduced length of stay and intensive care unit stay. 3 articles reported an increase in patient satisfaction after implementation of TCPs. 3 found that TCP led to a significant decrease in readmissions. After meta-analysis, TCPs were associated with significantly decreased readmission rates (OR: 0.68, p < 0.0001), length of stay (mean difference: -0.57, p < 0.00001), and emergency department visits (OR: 0.33, p < 0.0001). Conclusions: This systematic review and meta-analysis found that an overwhelming majority of the available literature supports the effectiveness of discharge planning on at least one measure of patient outcomes. However, the extent to which each facet of the TCP affects outcomes in elective neurosurgery remains unclear. Future efforts should be made to compare the effectiveness of different TCPs.

Objective: Axel Perneczky is responsible for conceptualizing the "keyhole" philosophy as a new paradigm of minimal invasiveness within cranial neurosurgery. Keyhole neurosurgery aims to limit approach-related traumatization and minimize brain retraction while still enabling the neurosurgeon to achieve operative goals. The supraorbital keyhole craniotomy (SOKC) and minipterional (pterional keyhole, PKC) approaches have become mainstays for clipping intracranial aneurysms. While studies have compared these approaches to the traditional pterional craniotomy for clipping cerebral aneurysms, head-to-head comparisons of these workhorse keyhole approaches remain limited. Methods: The authors queried three databases per PRISMA guidelines to identify all studies comparing the SOKC to the PKC for microsurgical clipping of cerebral aneurysms. Of 148 unique studies returned on initial query, a total of 5 studies published between 2013 and 2019 met inclusion criteria. Where applicable, quantitative meta-analysis was performed via the Mantel-Haenszel method using Review Manager v5.4 (Nordic Cochrane Centre, Cochrane Collaboration, Copenhagen, Denmark). Risk of bias (ROB) was assessed using the Cochrane ROBINS-I tool, and all studies were assigned a Level of Evidence (I-V). Results: Across all five studies, the mean age ranged from 53.0 to 57.5 years old, and the cohort consisted of more females (n = 403, 60.6%) than males. The proportion of patients presenting with ruptured aneurysmal SAH was comparable between the SOKC and PKC cohorts (p = 0.43). Clipping rate [defined as the rate of successful aneurysm clip deployment with successful intraoperative occlusion] (OR 1.52 [0.49, 4.71], I2 = 0%, p = 0.47), final occlusion rates (OR 1.27 [0.37, 4.32], p = 0.70), and operative durations (SMD 0.33 [-0.83. 1.49], I2 = 97%, p = 0.58) were comparable regardless of approach used. Furthermore, rates of intraoperative rupture (OR 1.51 [0.64, 3.55], I2 = 0, p = 0.34), postoperative hemorrhage (OR 1.49 [0.74, 3.01], I2 = 0, p = 0.26), postoperative vasospasm (OR 0.94 [0.49, 1.80], I2 = 63, p = 0.86), and postoperative infection (OR 0.70 [0.16, 2.99], I2 = 0%, p = 0.63) were equivocal across SOKC and PKC cohorts. Conclusion: The PKC and SOKC approaches appear to afford comparable outcomes when used for open microsurgical clipping of cerebral aneurysms in select patients with both ruptured and unruptured aneurysms. Both are associated with excellent clipping and occlusion rates, minimal perioperative complication profiles, and favorable postoperative neurologic outcomes. Further investigations are merited so clinicians can further parse out the indications and contraindications for each keyhole approach. [ABSTRACT FROM AUTHOR]

Background: Given the changes in the current learning environment health professionals are facing major challenges to keep up with current and updated information with the rapidly growing clinical and scientific knowledge base. Being able to identify relevant, high-quality articles, adapt or adopt to new learning strategies with an already intense workload are just a few of the main challenges. Self-directed learning is a key skill of competent health professionals and describes the process by which individuals evaluate their learning needs, goals and the resources needed for learning, however the emerging problems for professionals practicing SDL are manifold. Design: A qualitative, exploratory approach based on four research questions was used to understand how skilled neurosurgeons maintain and update their professional knowledge. Twenty-six neurosurgeons within the University Hospital of Bern completed a semi-structured interview. Results: One of the main findings concerns the differences between neurosurgeons regarding the SDL strategies they employ, which is compounded by their level of experience. All participants recognized that new or alternative learning approaches are necessary to manage the learning landscape, and for many this concerned their use of learning digital tools. Many, however, were unsure how to change their current behavior. Conclusion: The results highlight that positive factors influencing SDL in the workplace include learning leadership and support in identifying new or alternative strategies, an internal culture committed to learning as well as digital learning tools and networks. All are vital in managing the continuously evolving learning environment. [ABSTRACT FROM AUTHOR]

Background The effects of sleep deprivation on surgical performance have been well documented. However, reports on the effects of sleep deprivation on microneurosurgery are limited. This study aimed to investigate the effects of sleep deprivation on microneurosurgery. Methods Ten neurosurgeons participated in the anastomosis of a vessel model using a microscope in sleep-deprived and normal states. We evaluated the procedure time (PT), stitch time (ST), interval time (IT), number of unachieved movements (NUM), leak rate, and practical scale for anastomosis quality assessment. Each parameter was compared between normal and sleep-deprived states. Subanalyses were performed on the two groups based on PT and NUM under the normal state (proficient and nonproficient groups). Results Although no significant differences were noted in PT, ST, NUM, leak rate, or practical scale, IT was significantly prolonged under sleep deprivation compared with the normal state (mean: 258.8 ± 94.0 vs. 199.3 ± 74.9 seconds; p = 0.02). IT was significantly prolonged under sleep deprivation in the nonproficient group based on both PT and NUM (PT: 234.2 ± 71.6 vs. 321.2 ± 44.7 seconds, p = 0.04; NUM: 173.3 ± 73.6 vs. 218.7 ± 97.7; p = 0.02), whereas no significant difference was observed in the proficient group (PT: 147.0 ± 47.0 vs. 165.3 ± 61.1 seconds, p = 0.25; NUM: 173.3 ± 73.6 vs. 218.7 ± 97.7; p = 0.25). Conclusions Although IT was significantly prolonged under sleep deprivation in the nonproficient group, there was no decline in performance skills in either the proficient or nonproficient group. The effect of sleep deprivation may require caution in the nonproficient group, but it is possible that certain microneurosurgical outcomes can be achieved under sleep deprivation.

To evaluate the current state of neurosurgical care in Central Asia, identify the challenges and advancements, and propose recommendations to improve neurosurgical capabilities and access in Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. A comprehensive review of the neurosurgical infrastructure, availability of neurosurgeons, technological advancements, and healthcare policies in the five Central Asian countries. Analysis included published literature, healthcare reports, and expert opinions to assess the state of neurosurgical care and identify areas for improvement. Significant variation in neurosurgical care was observed across the region. Kazakhstan showed notable advancements, including an increased number of neurosurgeons and progress in specialized fields such as vascular neurosurgery and brain tumor management. Other countries, like Uzbekistan, Tajikistan, and Kyrgyzstan, made strides in improving neurosurgical care but still faced substantial challenges. Common issues included a shortage of neurosurgeons, limited facilities, and inadequate access to modern technology. The lack of research data further highlighted the need for urgent intervention. To enhance neurosurgical care in Central Asia, a multipronged approach involving targeted investments, policy reforms, international collaborations, and knowledge sharing is recommended. This includes establishing specialized neurosurgical training programs and fellowships, investing in infrastructure and technology, fostering international collaborations for training and research, introducing early neurosurgery education in medical schools, improving access to online education resources, and promoting telemedicine for consultations and follow-up care. These measures are necessary to expand access to essential neurosurgical care and improve outcomes in the regions. [ABSTRACT FROM AUTHOR]

Neurosurgery emphasizes the criticality of accurate differential diagnoses, with diagnostic delays posing significant health and economic challenges. As large language models (LLMs) emerge as transformative tools in healthcare, this study seeks to elucidate their role in assisting neurosurgeons with the differential diagnosis process, especially during preliminary consultations. This study employed 3 chat-based LLMs, ChatGPT (versions 3.5 and 4.0), Perplexity AI, and Bard AI, to evaluate their diagnostic accuracy. Each LLM was prompted using clinical vignettes, and their responses were recorded to generate differential diagnoses for 20 common and uncommon neurosurgical disorders. Disease-specific prompts were crafted using Dynamed, a clinical reference tool. The accuracy of the LLMs was determined based on their ability to identify the target disease within their top differential diagnoses correctly. For the initial differential, ChatGPT 3.5 achieved an accuracy of 52.63%, while ChatGPT 4.0 performed slightly better at 53.68%. Perplexity AI and Bard AI demonstrated 40.00% and 29.47% accuracy, respectively. As the number of considered differentials increased from 2 to 5, ChatGPT 3.5 reached its peak accuracy of 77.89% for the top 5 differentials. Bard AI and Perplexity AI had varied performances, with Bard AI improving in the top 5 differentials at 62.11%. On a disease-specific note, the LLMs excelled in diagnosing conditions like epilepsy and cervical spine stenosis but faced challenges with more complex diseases such as Moyamoya disease and amyotrophic lateral sclerosis. LLMs showcase the potential to enhance diagnostic accuracy and decrease the incidence of missed diagnoses in neurosurgery. [ABSTRACT FROM AUTHOR]

Despite global efforts to improve surgical care access, many low- and middle-income countries, especially in neurosurgery, face significant shortages. The Gambia exemplifies this, with only 1 fully qualified neurosurgeon serving its population of 2.5 million people. This scarcity results in higher morbidity and mortality. We aim to document the history and current state of neurosurgery in the Gambia to raise awareness and promote neurosurgery development. The study reviews the Gambia's health care system, infrastructure, neurosurgical history, workforce, disease burden, and progress, with information derived from reference sources as well as author experience and interviews with key partners in Gambian health care. Neurosurgery in the Gambia began in the 1970s, facing constraints due to competing health care demands. Significant progress occurred much later in the early 2010s, marked by the initiation of Banjul Neuro Missions and the establishment of a dedicated neurosurgery unit. We report significant progress with neurosurgical interventions in the past few years showcasing the unit's dedication to advancing neurosurgical care in the Gambia. However, challenges persist, including a lack of trained neurosurgeons, equipment shortages such as ventilators and diagnostic imaging. Financial barriers for patients, particularly related to the costs of computer tomography scans, pose significant hurdles, impacting the timely diagnosis and intervention for neurological conditions. Neurosurgery in the Gambia is progressing, but challenges like equipment scarcity hinder further progress. We emphasize the need for addressing cost barriers, improving infrastructure, and fostering research. Engaging the government and international collaborations are vital for sustained development in Gambian neurosurgery. [ABSTRACT FROM AUTHOR]

Medical professionals who assume multiple roles as clinicians and researchers are commonly found in hospitals worldwide. Likewise, in many Chinese hospitals, particularly among early-career medical professionals with MD and PhD degrees, active engagement in both clinical practice and scientific research is expected. In the current ethnographic study, the cultural-historical activity theory is used to explore how three early-career neurosurgeons at a tier-one northern Chinese hospital conduct and write research for publishing in Science Citation Index (SCI)-indexed journals in addition to handling their heavy clinical workload. Drawing on multiple sources of qualitative data, including semi-structured interviews, two-week naturalistic observations, field notes, photographs, and daily activity logs with three neurosurgeons, the study findings highlight Chinese neurosurgeons conduct and write up their research using patient data and collaborating with laboratories while seeking academic language editing and peer feedback. Ethical considerations of clinician-researchers' scholarly publishing process, implications for researching medical professionals' boundary crossings, and future research directions are also discussed.

The vein of Rolando, also known as the central sulcal vein, is a critical superficial cerebral vein located in the central sulcus, playing a pivotal role in the venous drainage of the motor and sensory cortices. Named after the Italian anatomist Luigi Rolando, this vein serves as a crucial anatomical landmark in neurosurgery, guiding surgeons to approach critical brain structures with minimal damage. This article explores the anatomy and clinical significance of the vein of Rolando, emphasizing its role in neurosurgery and neuroimaging. Advanced imaging techniques such as functional MRI (fMRI), Magnetic Resonance Venography (MRV), and CT Angiography have enhanced the ability to diagnose and preserve this vein, reducing surgical risks. The article also discusses the interconnectedness of the vein of Rolando with other cerebral veins like the vein of Trolard and underscores the importance of understanding venous variations and drainage patterns for successful surgical outcomes. Preventive measures to protect the vein during neurosurgery are essential to prevent complications such as venous congestion and intracranial pressure. This overview highlights the necessity for precise anatomical knowledge and advanced diagnostic tools in optimizing neurosurgical procedures and patient care. [ABSTRACT FROM AUTHOR]

Background: Samii Type-D jugular foramen schwannomas (JFSs) are the most challenging for neurosurgeons because of anatomical complexity. Various neurosurgical approaches have been described to gain access to JF. Methods: We present a female with incidental diagnosis of the Type-D JFS. Complete radical resection was achieved via the carotid triangle approach without any bony structure removal. And the patient was discharged asymptomatic and without new-developed neurological deficits. Conclusions: The carotid triangle is a secure and appropriate approach for some cases of selected Type-D JFSs. However, the specific indications of this approach should be further explored and investigated. [ABSTRACT FROM AUTHOR]

Purpose: The gold standard for diagnostics in primary central nervous system lymphoma (PCNSL) is histopathological diagnosis after stereotactic biopsy. Yet, PCNSL has a multidisciplinary diagnostic work up, which associated with diagnostic delay and could result in treatment delay. This article offers recommendations to neurosurgeons involved in clinical decision-making regarding (novel) diagnostics and care for patients with PCNSL with the aim to improve uniformity and timeliness of the diagnostic process for patients with PCNSL. Methods: We present a mini review to discuss the role of stereotactic biopsy in the context of novel developments in diagnostics for PCNSL, as well as the role for cytoreductive surgery. Results: Cerebrospinal fluid-based diagnostics are supplementary and cannot replace stereotactic biopsy-based diagnostics. Conclusion: Histopathological diagnosis after stereotactic biopsy of the brain remains the gold standard for diagnosis. Additional diagnostics should not be a cause of diagnostic delay. There is currently no sufficient evidence supporting cytoreductive surgery in PCNSL, with recent studies showing contradictive data and suboptimal study designs. [ABSTRACT FROM AUTHOR]
