The Natural Course of Myxopapillary Ependymoma : An Unusual Case Report and Review of The Literature.
Spinal cord ependymomas are the most frequent primary intramedullary tumors of the cord in middle age (40-60 years of age). Myxopapillary ependymomas are low-incidence tumors and occur in the cauda equina and conus medullaris. They are typically described as fleshy, sausage-shaped, vascular lesions. ⋯ Myxopapillary ependymomas grow slowly and are well defined by MRI. Advancements in radiologic technology and surgical equipment have allowed this tumor type to be treated successfully. Unfortunately, if untreated, these lesions have poor prognosis and result in clinical symptoms such as paraparesis. Surgical treatment of these lesions using total resection was performed total resection and was associated with an excellent postoperative outcome. We highlight the natural course of myxopapillary ependymomas.

Observational Study
Regional Variation in Opioid Use After Lumbar Spine Surgery.
The aim of this study was to investigate regional variations in use of opioids after lumbar decompression and fusion surgery for patients with symptomatic lumbar stenosis or spondylolisthesis. ⋯ Our study suggests that regional variations may exist in the use of opioids after lumbar decompression and fusion surgery for patients with symptomatic lumbar stenosis or spondylolisthesis.

We studied the postoperative morphology of the dura mater and analyzed the probability of epidural hematoma (EH) after anterior controllable antedisplacement and fusion (ACAF). ⋯ The dura mater can protect the spinal cord like a suspensory tent after ACAF. The occurrence of EH is rare when ACAF is used to treat OPLL and DKS.

Review Historical Article
The Siberian lancet, one more possible innovative example of scalpel's contribution to the evolution of surgical anatomy and neurosurgery.
Several primitive scalpels were used since the eve of surgical procedures. Numerous bronze knifes discovered in the Altai mountains region from the Xiongnu-Xianbei-Rouran period mold a hypotheses for a possible medical use. ⋯ Strong indications imply that those cutting tools, except for domestic usage, were one more example of scalpel's contribution to the evolution of surgical anatomy and neurosurgery.

Several outcome prediction systems have been developed to evaluate aneurysmal subarachnoid hemorrhage (aSAH). However, they can be difficult to use and can contain subjective elements. We sought to identify the predictors of aSAH outcomes at discharge to provide an accurate and reliable scoring system. ⋯ We propose a grading scale to predict discharge mortality and functional outcomes in patients with aSAH. The proposed scale outperformed most other outcome prediction scales. The proposed scale contains objective elements, is easy to apply by memory, and can be a useful and effective measure to predict aSAH outcomes.
