ABSTRACT

BACKGROUND: Providing a comprehensive and effective neurosurgical service requires adequate numbers of well-trained, resourced, and motivated neurosurgeons. The survey aims to better understand 1) the demographics of young neurosurgeons worldwide; 2) the challenges in training and resources that they face; 3) perceived barriers; and 4) needs for development. METHODS: This was a cross-sectional study in which a widely disseminated online survey (April 2018-November 2019) was used to procure a nonprobabilistic sample from current neurosurgical trainees and those within 10 years of training. Data were grouped by World Bank income classifications and analyzed using χ2 tests because of its categorical nature. RESULTS: There were 1294 respondents, with 953 completed responses included in the analysis. Of respondents, 45.2% were from high-income countries (HICs), 23.2% from upper-middle-income countries, 26.8% lower-middle-income countries, and 4.1% from low-income countries. Most respondents (79.8%) were male, a figure more pronounced in lower-income groups. Neuro-oncology was the most popular in HICs and spinal surgery in all other groups. Although access to computed tomography scanning was near universal (98.64%), magnetic resonance imaging access decreased to 66.67% in low-income countries, compared with 98.61% in HICs. Similar patterns were noted with access to operating microscopes, image guidance systems, and high-speed drills. Of respondents, 71.4% had dedicated time for neurosurgical education. CONCLUSIONS: These data confirm and quantify disparities in the equipment and training opportunities among young neurosurgeons practicing in different income groups. We hope that this study will act as a guide to further understand these differences and target resources to remedy them.

ABSTRACT

BACKGROUND: Strengthening health systems requires attention to workforce, training needs, and barriers to service delivery. The World Federation of Neurosurgical Societies Young Neurosurgeons Committee survey sought to identify challenges for residents, fellows, and consultants within 10 years of training. METHODS: An online survey was distributed to various neurosurgical societies, personal contacts, and social media platforms (April-November 2018). Responses were grouped by World Bank income classification into high-income countries (HICs), upper middle-income countries (UMICs), low-middle-income countries (LMICs), and low-income countries (LICs). Descriptive statistical analysis was performed. RESULTS: In total, 953 individuals completed the survey. For service delivery, the limited number of trained neurosurgeons was seen as a barrier for 12.5%, 29.8%, 69.2%, and 23.9% of respondents from HICs, UMICs, LMICs, and LICs, respectively (P < 0.0001). The most reported personal challenge was the lack of opportunities for research (HICs, 34.6%; UMICs, 57.5%; LMICs, 61.6%; and LICs, 61.5%; P = 0.03). Other differences by income class included limited access to advice from experienced/senior colleagues (P < 0.001), neurosurgical journals (P < 0.0001), and textbooks (P = 0.02). Assessing how the World Federation of Neurosurgical Societies could best help young neurosurgeons, the most frequent requests (n = 953; 1673 requests) were research (n = 384), education (n = 296), and subspecialty/fellowship training (n = 232). Skills courses and access to cadaver dissection laboratories were also heavily requested. CONCLUSIONS: Young neurosurgeons perceived that additional neurosurgeons are needed globally, especially in LICs and LMICs, and primarily requested additional resources for research and subspecialty training.

ABSTRACT

BACKGROUND: Meningiomas are the most common benign intracranial neoplasms in adults, but they have a lower incidence in children. Rhabdoid meningioma is a rare subtype of meningioma and is classified as World Health Organization grade III. CASE DESCRIPTION: We present a very rare case of a 9-year-old boy who presented to our institution with a history of headache, dizziness, and vomiting without neurologic deficit. The investigation showed a posterior fossa tumor with hemorrhage inside and hydrocephalus. He underwent tumor resection, and pathology showed rhabdoid meningioma. The patient had extensive recurrence after only 5 months, including extension to the neck, mediastinal veins, and heart. He was treated surgically and received adjuvant chemotherapy followed by radiation therapy. CONCLUSIONS: Rhabdoid meningioma is a malignant subtype of meningioma that occurs very rarely in pediatric patients. Additionally, rhabdoid meningioma, when it does occur in pediatric patients, has a high tendency to recur. Radical surgical resection with adjuvant radiotherapy is essential to prolonging survival. This is the first case with extracranial extension to the mediastinal veins and heart.

ABSTRACT

There are few reported cases of tectocerebellar dysraphia with occipital encephalocele (TCD-OE) in the literature. This malformation was first described by Padget and Lindburg in 1972 and consists of an occipital encephalocele, a cerebellar midline defect, inverted cerebellum, and deformity of the tectum. Occurrence is believed to be sporadic with a male predominance and a usually poor prognosis. We report a patient with brain MRI findings compatible with tectocerebellar dysraphia and occipital encephalocele. Additional features consistent with Joubert syndrome including deepened interpeduncular fossa, as well as elongated, thickened, and anteroposteriorly oriented superior cerebellar peduncles, were noted. The patient's evaluation also revealed a homozygous mutation of the TMEM231 gene, known to cause Meckel-Gruber and Joubert syndromes. Our case represents the first reported genetic confirmation that tectocerebellar dysraphia with occipital encephalocele is not a distinct nosological entity but likely a phenotypic variation of Joubert syndrome.
