Review Case Reports
Glioneuronal Heterotopia Presenting as Cerebellopontine Angle Tumor of Cranial Nerve VIII.
Vestibular schwannomas and meningiomas account for the great majority of lesions arising in the cerebellopontine angle. In this report, we present a case of glioneuronal heterotopia, also known as glioneuronal hamartoma, arising from cranial nerve VIII, which is an extremely uncommon lesion. Important radiologic and surgical aspects are reviewed, which may help in early recognition and intraoperative decision making when these lesions are encountered. ⋯ Ectopic glioneuronal tissue of cranial nerve VIII is a rare non-neoplastic lesion and should be considered in the differential diagnosis of unusual-appearing intracanalicular and cerebellopontine angle lesions. The congenital and benign nature of this entity makes observation a valid option for these cases, although they are so infrequent that they are often presumptively managed as vestibular schwannomas. Attempts to radically resect these lesions may result in higher rates of hearing loss or facial palsy due to their continuity with cranial nerves.

Review Case Reports
Trigeminal Neuralgia Secondary to Osteoid Osteoma of the Petrous Bone: Report of 4 Cases and Brief Review of Literature.
To retrospectively analyze clinical data of 4 patients with trigeminal neuralgia (TN) secondary to osteoid osteoma (OO) of the petrous bone and discuss treatment for this rare disease. ⋯ TN secondary to petrous bone OO is extremely uncommon. Surgical decompression is an effective treatment for patients with petrous bone OO and associated TN.

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.

Louis Victor Leborgne was a patient of Paul Broca. "Monsieur Leborgne," as Broca would call him, was also known around in the hospital by the nickname "Tan." His neurologic condition left him with difficulty in speaking, and he could only speak the word "Tan." Leborgne spent nearly half of his entire life in the hospital. He was initially admitted into the psychiatry division of the hospital and was later transferred under the care of Broca toward the end of his life. ⋯ Leborgne's condition was the cornerstone in the evolution of this discovery. More than 150 years have passed since the death of Leborgne, yet Leborgne's brain continues to attract researchers investigating the mysteries of human speech.

Randomized Controlled Trial
Efficacy of Caudal Epidural Steroid Injection with Targeted Indwelling Catheter and Manipulation in Managing Patients with Lumbar Disk Herniation and Radiculopathy: A Prospective, Randomized, Single-Blind Controlled Trial.
Lumbar disk herniation (LDH) is considered a common cause of lumbosacral radiculopathy. Epidural steroid injection is a common method to treat inflammation associated with low back-related leg pain. Spinal manipulations are widely used, and systematic reviews have also shown that these manipulations are more effective than placebos. ⋯ Both methods were effective in reducing pain intensity and functional disability compared with pretreatment. The Catheter Group showed a more significant decrease in visual analog scale and greater changes in JOA and ODI scores of short/term follow-up, compared with the No-Catheter Group. The therapy project was safe.
