Resection of left hemisphere (LH) tumors is often complicated by the risks of causing language dysfunction. Although neurosurgeons' concerns when operating on the presumed dominant hemisphere are well known, literature evaluating laterality as a predictive surgical parameter in glioblastoma (GB) patients is sparse. We evaluated whether tumor laterality correlated with surgical performance, functional outcome, and survival. ⋯ Patients with LH tumors had a pronounced KPS score decline and shorter progression-free survival without effects on overall survival. This observation might partially be attributed to a more conservative surgical resection. Further investigation is needed to assess whether systematic use of awake surgery and intraoperative mapping results in increased EOR and improved quality survival of patients with GB.

Review Biography Historical Article
John C. Vangilder (1935-2007): Neurosurgical Leader and Founder of the Department of Neurosurgery at the University of Iowa.
John C. VanGilder, the former professor and chairman of neurosurgery at The University of Iowa died on August 27, 2007 after making a lasting impact to the field of neurosurgery both in the United States and abroad. In this manuscript, we review VanGilder's life and achievements. ⋯ He was appointed to faculty positions first at Yale University and later at The University of Iowa, where he became professor and later chairman of the Division of Neurosurgery. VanGilder also served as president of the Society of Neurological Surgeons (1997-1998), president of the Neurosurgical Society of America (1998-1999), chairman of the American Board of Neurological Surgery (1997-1998), and vice president of the American Academy of Neurological Surgery. At The University of Iowa, VanGilder played a key role in the transition of the Division of Neurosurgery to a Department of Neurosurgery and mentored several neurosurgeons who would go on to become department chairmen or make other important neurosurgical contributions at other medical schools in the United States.

To probe the relationship among cement volume/fraction, imaging features of cement distribution, and pain relief and then to evaluate the optimal volume during percutaneous vertebroplasty. ⋯ In osteoporotic vertebral compression fracture with mild/moderate fracture severity at the single thoracolumbar level, the intravertebral cement volume of 4-6 mL could relieve pain rapidly. The optimal VF% was 19.78%, which could achieve satisfactory cement distribution. With the increase of VF%, the incidence of cement leakage would also increase.

Clinical and radiographic degenerative spondylolisthesis (CARDS) classification defines a distinct subset of patients with kyphotic angulation at the involved segment (type D). Research using CARDS classification to investigate motion characteristics at involved segments or patient-related outcomes (PROs) following surgical intervention is sparse. We investigated the relationship between CARDS type D spondylolisthesis and dynamic instability and PROs in type D versus non-type D spondylolisthesis. ⋯ CARDS type D spondylolisthesis is a distinct subset associated with dynamic instability and worse PROs. Higher improvement in PROs can be achieved in CARDS type D spondylolisthesis after surgery.
