Endoscopic-Assisted Microsurgical Resection of a Recurrent Conus Medullaris Dermoid Tumor.
Surgery for intramedullary spinal cord tumors presents multiple unique challenges, including the need to operate through a very narrow myelotomy window. In this operative video, we demonstrate the use of the surgical endoscope in an operation performed on a 35-year-old woman. ⋯ After consenting to surgery, she underwent reoperative posterior lumbar approach to resection of her tumor. In our video we demonstrate our use of a surgical endoscope, which allowed us to minimize the extent of our myelotomy and resect tumor rostral and caudal to our myelotomy, thus minimizing the risk of damage to normal spinal cord that is displaced by tumor (Video 1).

Inducing the differentiation of glioma cells into neuron-like cells may be an effective strategy to combat glioma. The histone deacetylase 1/RE-1 silencing transcription factor (HDAC1/REST) complex regulates the expression of multiple neuronal genes. In this study, we analyzed the presence and significance of this regulatory effect in glioma based on bioinformatics methods. ⋯ This study suggested that HDAC1/REST may be involved in maintaining the malignant phenotype of glioma cells and the stem cell status of glioma stem cells by inhibiting the expression of neuronal markers, which promote the progression of glioma.

Brain injury following head trauma occurs in 2 stages, namely an early stage attributable to mechanical damage and a delayed stage resulting primarily from neuroinflammation. In this study, we examined early proinflammatory cytokine upregulation in an animal model of traumatic brain injury (TBI) and examined the effects of early anti-inflammatory therapy on neuroinflammation, neuropathology, and systemic inflammatory activity. ⋯ The administration of anti-inflammatory drugs or vitamin D analogs in the early period following TBI might help to reduce secondary injury from neuroinflammation.
