The use of "withdrawal of care" and impact upon outcomes among patients with subarachnoid hemorrhage (SAH) is not well studied. ⋯ Although "withdrawal of care" was effective in limiting hospital charges and resource use, caution is needed to avoid disproportionately high mortality. The prominent relationship between race/ethnicity, insurance status, and hospital location with "withdrawal of care" raises concerns that factors other than severity of disease influence decision making.

When resecting gliomas, extra-axial tumors, or their overlying cortex, cortical veins may become suspended over the resection cavity and ultimately prolapse and kink into the cavity, promoting venous thrombosis. To prevent this, we describe a technique to secure a Gelfoam scaffold beneath the cortical vein at the edge of the resection cavity to prevent kinking and possible thrombosis from taking place after tumor removal. Depending on the diameter of the resection cavity, this can be done at 1 or both edges of the resection cavity to prevent prolapse of the vein into the cavity. In our experience with this technique, during the past 10 years, there have been no cases of venous thrombosis after tumor removal on postoperative imaging or clinical examination.

From the cell of Schwann to schwannoma--a century's fruition.
The word "schwannoma" is pervasive throughout the neurosurgical community. However, little is known about the origin of the cell of "Schwann cell," the manifestation of the tumor's nomenclature, or the prominent physicians who studied its etiopathogenesis. Schwann was a founding father of cellular theory and one of the greatest scientists of the 19th century. ⋯ He believed that these tumors have a non-nerve cell, non-Schwann cell origin. He classified the tumors arising from the Schwann cell sheath as peripheral gliomas and articulated, "If any tumors are to be called schwannomas, these should be." The neurofibroma of von Recklinghausen was recognized as a separate entity, as described by von Recklinghausen himself. Murray and Stout proposed that schwannomas are essentially benign in nature clarifying the abstruseness of the benign or malignant nature of schwannoma.
