Irreversible hypoglossal nerve injury and concomitant trigeminal system dysfunction after anterior surgery to the cervical spine: A case report and literature review.
The anterior surgical approach to the cervical spine is known to be safe, and damage to the hypoglossal nerve and trigeminal pathway after the surgery is uncommon. However, once damage to those nerves occurs, the patient's quality of life can be severely impaired by discomfort and disability. ⋯ It is important to be aware of the complexity of the anatomy of vulnerable structures, including hypoglossal nerves and the trigeminal nerve system at the cervical spine level, to prevent damage to important neural structures during surgical procedures.

Can Osteoblastoma evolve to malignancy? A challenge in the decision-making process of a benign spine tumor.
Osteoblastoma is a rare benign aggressive tumor, with one third occurring in the spine. Conversion of osteoblastoma to osteosarcoma is uncommon, and histologically proven conversion has been rarely reported. ⋯ The rare occurrence of osteoblastoma converting to osteosarcoma imparts several lessons, including performing Enneking appropriate surgery for benign aggressive tumors (Enneking stage 3) and always performing a biopsy, particularly at the time of recurrence if imaging is not pathognomonic for a benign primary spine tumor.

Bibliometric analyses are widely used to gauge the scholarly impact of any scientific publication. We conducted a bibliometric analysis of the 100 most influential articles on glioblastoma multiforme (GBM). We searched Scopus using the keywords "Glioblastoma multiforme," "GBM," Glioblastoma," and "Grade IV glioma." A list of the top 100 articles was prepared. ⋯ There were 12 authors who had ≥5 articles in the top 100 citation list. Only 31% of the articles were funded by public and private sector organizations. Our analysis highlights the characteristics of the most influential articles on GBM and provides valuable insight into the research that has been conducted in this field.

Review Historical Article
A thoracic surgeon among neurosurgeons: Edward Archibald's forgotten influence on the professionalization of neurosurgery.
Edward Archibald, Professor of Surgery at McGill University (1904-1945), Montreal, Canada, was the foremost thoracic surgeon of his generation. Although instrumental in establishing the American Board of Surgery and in standardizing surgical training, he was also influential as a neurosurgeon. Archibald, an early member invited by Harvey Cushing to join the Society of Neurological Surgeons, helped establish neurosurgery as a distinct, specialized discipline. ⋯ Archibald's personal acquaintance with the principal neurosurgeons of the day, his insight into their personalities, their prominence in the field, and their career paths played a critical role in influencing Penfield to consider relocating to Montreal from Columbia University, despite tempting offers from Boston and Philadelphia. However, it was Archibald's support and mentorship for the creation of an academic center that finally convinced Penfield to move to McGill University. As one of the most influential surgeons of the early 20th century and a founding figure of modern neurosurgery, Archibald is an important part of neurosurgery's legacy.

Myxopapillary ependymoma (MPE) is a rarely reported lesion of the spinal cord in the pediatric population. Based on their low mitotic index and slow-growth, MPEs are classified as low-grade glial tumors. However, MPEs have malignant characteristics, such as distant neural axis and extraneural axis dissemination. We present the long-term surgical resection outcomes of 5 consecutive pediatric MPE cases and the results of a literature search for reported cases of pediatric spinal MPE. ⋯ Even with GTR, pediatric MPE has a high propensity for neural axis dissemination. We recommend close clinical and radiologic follow-up for pediatric patients with MPE.
