Magnetic resonance imaging correlation in pediatric spinal cord injury without radiographic abnormality.
The authors conducted a study to determine correlations between clinical syndromes and early magnetic resonance (MR) imaging-documented findings in children with spinal cord injury without radiographic abnormality (SCIWORA). ⋯ In this series, the predominant neurological presentation of SCIWORA was a mild, partial syndrome that resolved within 72 hours. Magnetic resonance imaging revealed abnormal features only in those patients with complete neurological deficits. These findings suggest that in the acute setting conventional MR imaging sequences may lack the sensitivity to demonstrate neural and extraneural abnormalities associated with partial or temporary neurological deficits of SCIWORA, even when those deficits persist beyond 72 hours.

Case ReportsEagle syndrome: entrapment of the glossopharyngeal nerve? Case report and review of the literature.
Eagle syndrome is characterized by unilateral pain in the oropharynx, the side of the face, and the earlobe. It is caused by an elongated styloid process; resection of the elongated process eliminates the pain. Although quite rare, this syndrome is well represented in the oral, ear, nose, and throat surgery literature. ⋯ After the diagnosis of Eagle syndrome was made based on radiographic findings and was confirmed using a local anesthetic block, resection of the elongated styloid process was performed, resulting in complete and lasting pain relief. Eagle syndrome, which is caused by compression of the glossopharyngeal nerve as it passes the elongated styloid process, may be classified as an entrapment syndrome deserving of neurosurgical attention. The goal of this report is to familiarize neurosurgeons with Eagle syndrome and its diagnostic work up and treatment.

Ischemic depolarization monitoring: evaluation of protein synthesis in the hippocampal CA1 after brief unilateral ischemia in a gerbil model.
The authors investigate whether depolarization monitoring is an accurate index of ischemic damage in a gerbil model of unilateral ischemia and assess the effects of brief cerebral ischemia on protein synthesis in this model. ⋯ In this study the authors demonstrate that monitoring of ischemic depolarization is a useful method to predict neuronal damage in the hippocampal CA1 in this model, and they identify subtle changes in protein synthesis after brief ischemia. Sublethal ischemia was divided into three categories by its depolarization period (< 90 seconds, 90-180 seconds, and > 180-210 seconds) with regard to changes in protein synthesis.

Biography Historical ArticleGeorge J. Heuer: forgotten pioneer neurosurgeon at the Johns Hopkins Hospital.
George J. Heuer was a pioneer in neurosurgery at The Johns Hopkins Hospital in the early 20th century; he trained under Harvey Cushing and acted as a mentor to Walter Dandy. In his early career, Heuer focused on research and clinical work in the field of neurosurgery and temporarily led the neurosurgery section at Johns Hopkins. ⋯ Throughout his academic years, Heuer continued to operate on the nervous system and to perform spinal cord and peripheral nerve surgery. He played an important role along with Cushing and Dandy in the creation of neurosurgery as a specialty, but he is rarely given credit for this accomplishment. The authors describe Heuer's contributions to neurosurgery as well as his distinguished surgical career.
