Pediatric fibromyxoid brachial plexus tumor with YWHAZ::PLAG1 gene fusion: a case report.

Pediatric fibromyxoid soft tissue tumors may be associated with gene fusions such as YHWAZ::PLAG1, with only three reported cases in the literature. We present the fourth case, a 13-year-old male with a pediatric fibromyxoid brachial plexus tumor with YWHAZ::PLAG1 gene fusion. This is also the first case to be reported in an adolescent, in the brachial plexus, and in the Philippines. The patient presented with a 10-year history of a slowly growing left supraclavicular mass and a 1-year history of intermittent dysesthesia in the left upper extremity. Neurologic examination was unremarkable. Imaging revealed a large left supraclavicular lesion with intrathoracic extension. Surgical excision was performed, and histopathology revealed a fibromyxoid tumor with YWHAZ::PLAG1 gene fusion. Although previous examples of this gene fusion pointed toward lipoblastoma as their primary pathology, our tumor does not completely fulfill the current diagnostic criteria for a lipoblastoma and may represent an intermediate form of the disease. Our case is unique not only because it is the first reported adolescent patient harboring such a lesion but also because of the relatively lengthy natural history exhibited by the tumor prior to its resection. This provided us with valuable information about its behavior, which suggests a more indolent growth pattern. This case also highlights the clinical importance of molecular testing of tumors, where recognition of disease entities can assist clinicians in deciding and advocating for the proper management.

Neurosurgical research in Southeast Asia: A bibliometric analysis.

OBJECTIVES: Bibliometric analysis can provide insight into the growth, development and dissemination of research in neurosurgery. Little work has been done to examine the role of country-specific characteristics affecting research productivity. We aimed to characterize andcompare the research productivity among SEA countries in terms of bibliometric indicesand determine associations with country-specific factors. METHODS: We performed a systematic search of all articles by authors affiliated with a neurosurgical department in any of the Southeast Asian countries, indexed in 3 databases from inception to June 10, 2020. Bibliometric indices - number of publications, number of citations, average citations per publication, h-index, and the i-10-index - were computed for each country. Correlations between the indices and country-specific characteristics (population size, GDP per capita, percentage of GDP allocation to research and development (R&D), number of neurosurgeons, number of neurosurgeons per capita, and number of collaborations with non-SEA authors) were determined. RESULTS: The number of publications showed an increasing trend up to 2019. Most studies were cohort studies (37%) or case reports or series (37%). Of the country-specific factors analyzed, only percentage of the GDP allocated to R&D was positively correlated with number of publications (p = 0.0004), total citations (p < 0.0001), H-index (p < 0.0001), and i(10)-index (p < 0.0001). Number of collaborations also positively correlated with the same indices. CONCLUSION: Our bibliometric analysis showed increasing contribution by neurosurgeons in the SEA region. Correlational analysis support the view that increased R&D budget allocation and international collaboration can improve neurosurgical research capacity and productivity.

Perceptions and Likelihood of Medical Students to Pursue a Career in Neurosurgery: Findings from the Philippines.

BACKGROUND: The number of neurosurgeons in the Philippines is less than ideal for its population, so there is a need to recruit and train more. This study aimed to determine medical students' perception of neurosurgery and their likelihood of pursuing a career in this specialty. METHODS: A cross-sectional survey was conducted of medical students in the Philippines to assess their perceptions and likelihood of pursuing a career in neurosurgery. Data obtained were analyzed using descriptive statistics and a χ2 test with a significance level of 0.05. RESULTS: A total of 627 medical students completed the survey, with a response rate of 72.4%. The mean age was 23.8 years, and almost half (49.1%) were women. They had mostly negative perceptions of neurosurgery, and only 18.7% were likely to pursue a career in this specialty. Reasons included poor work-life balance, poor understanding of neuroscience and neurosurgery, and the self-perceived lack of manual dexterity. The most common sources of their perceptions included lectures, movies, and neurosurgery residents and consultants whom they met in hospital. Previous exposure to neurosurgery lectures or rotations, going back to their hometown to work, and having a physician parent were associated with a higher likelihood of pursuing neurosurgery. CONCLUSIONS: Our study showed that medical students' perceptions of neurosurgery were generally negative and that only 18.7% were likely to pursue it as a career. Major changes would have to be made to improve students' perceptions to attract more students to the field and increase the neurosurgical workforce.

Top 100 Most Cited Neurologic and Neurosurgical Articles on COVID-19: A Bibliometric Analysis.

OBJECTIVE: With the exponential growth of literature on coronavirus disease 2019 (COVID-19), we aimed to identify and characterize the 100 most cited COVID-19-related articles in neurology and neurosurgery. METHODS: In March 2021, we performed a title-specific search of the Scopus database using ("neurology" or "neurologic" or "neurosurgery" or "neurosurgical") and "COVID" as our search query term without date restrictions. The top 100 most cited English-language articles were obtained and reviewed. RESULTS: Our search yielded 9648 articles published from December 2019 to March 2021. Bibliometric analysis of the top 100 articles found that the most cited article had a citation count of 1741 and was the first to report on the detailed neurologic manifestations of the disease; Neurology had the most number of publications; the majority of the primary authors were neurologists, but 35% were from nonneuroscience specialties; the United States, Italy, the United Kingdom, China, and Germany were the top contributors, with a combined total of 77%; most of the publications were correspondence or editorial articles; and most articles discussed the neurologic manifestations and complications of patients with COVID-19. CONCLUSIONS: This study identified the top 100 most cited neurologic or neurosurgical COVID-19-related articles published to date. This list can be used to identify high-impact studies that will help health care practitioners in clinical decision making and researchers in navigating key areas of study and guiding future research.

Pediatric choroid plexus papilloma arising from the cerebellopontine angle: systematic review with illustrative case.

INTRODUCTION: Choroid plexus tumors are uncommon intraventricular tumors that develop from the choroid plexus of the central nervous system. Choroid plexus papillomas arising from the cerebellopontine angle have been reported to almost exclusively occur in adults and are rarely found in children. METHODS: We report a systematic review conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines of SCOPUS and PubMed databases for case reports and case series of choroid plexus papillomas arising in the cerebellopontine angle in the pediatric population and discuss clinical presentation, imaging features, management options, and outcomes. We also report a case managed at our center. RESULTS: Ten cases of pediatric choroid plexus papillomas arising in the cerebellopontine angle were identified from the systematic review in addition to the case reported here, resulting in a total of eleven cases. The patients' median age was 8 years with a slight female sex predilection (1.2:1). Patients most commonly presented with headache, cerebellar signs, and cranial nerve palsies with median duration of symptoms at 4 months. All patients underwent surgical treatment with majority achieving gross total excision. No deaths were reported at median follow-up of 12 months. Complete neurologic recovery was attained in seven cases while partial recovery was seen in two cases. CONCLUSION: Choroid plexus papillomas found in the cerebellopontine angle in the pediatric population are extremely rare but they should be considered in the differential diagnosis. Complete surgical resection is the mainstay of treatment with excellent outcomes achievable in majority of patients.
