Historical Article
Neurosurgery at the Radcliffe Infirmary, Oxford: a history.
Neurosurgery started in Oxford in 1938. In this article, we commence the story of Oxford neurosurgery with Thomas Willis and trace the historical thread through William Osler, Charles Sherrington, John Fulton, and Harvey Cushing to Hugh Cairns. The department in Oxford is renowned for the training of neurosurgeons. ⋯ An increasing emphasis placed on research has resulted in the creation of two posts; each consists of half-time clinical neurosurgery and half-time research. Hugh Cairns organized the department along "Cushing lines." This organization still exists, allowing us to treat a large number of patients with relatively few beds and an average length of patient stay less than 6 days. We look to the future with confidence.

Meta Analysis Comparative Study
The cost effectiveness of stereotactic radiosurgery versus surgical resection in the treatment of solitary metastatic brain tumors.
Solitary metastatic brain tumors are the most common intracranial neoplasms encountered by neurosurgeons. Surgical resection of brain metastasis with whole brain radiotherapy (WBR) significantly increases survival in comparison with WBR alone. Stereotactic radiosurgery (SR) seems to provide results that are similar to those of surgical resection. ⋯ A sensitivity analysis revealed that large changes in key assumptions would be required to change the analysis outcome. Equalization of the incremental cost effectiveness of the two treatments would require one of the following: 1) a 38.7% reduction in SR annual case volume, 2) a 34.7% increase in SR procedure cost, 3) a 18.8% reduction in surgical resection procedure cost, 4) a 240.5% increase in SR morbidity cost, 5) a 12.7% reduction in SR median survival, 6) a 16.8% increase in surgical resection median survival. Elimination of all surgical resection morbidity cost would still result in superior incremental cost effectiveness for SR.(ABSTRACT TRUNCATED AT 400 WORDS)

Intentional cranial deformation: a disappearing form of self-mutilation.
Of the forms of human self-mutilation that have been recorded, few have been so widespread and long lasting as intentional cranial deformation. The earliest known record of the practice is from Iraq and dates back to 45,000 BC. ⋯ Although tatooing, ear piercing, and circumcision are commonly practiced in our society, cranial deformation has almost completely disappeared from contemporary cultures, with the exception of isolated groups in Africa and South America. Intentional cranial deformation is intriguing for those who study the human cranium.

Intracerebroventricular morphine analgesic for the treatment of cancer pain was administered, using implanted access ports, in 82 patients from 1984 to January 1994. All of the patients who were selected for treatment were no longer responsive and had developed drug side effects to oral or parenteral opiates in varying doses (60-400 mg/d). The mean follow-up was 66 days (range, 12-443 d) for this series of 82 patients. ⋯ The initial doses of morphine were a mean of 0.30 mg (range, 0.10-2 mg), and the final doses were a mean of 2.5 mg (range, 0.10-60 mg). The results show that the ratio of the terminal dose to the initial dose increased more rapidly for patients who had a follow-up of over 60 days. However, the increase seems to have been because of the progress of the disease rather than because of drug tolerance.

Case Reports
Resolution of traumatic hypertrophic periodontoid cicatrix after posterior cervical fusion: case report.
The case of a 38-year-old man with delayed myelopathy 19 years after a nontreated odontoid type II fracture is reported. Magnetic resonance imaging of the craniocervical region revealed a periodontoid cicatrix. The clinical syndrome improved, and complete resolution of the retro-odontoid mass was achieved 9 months after posterior cervical fixation. The implications of this unique case for the management of myelopathy associated with nonunion of odontoid fractures are discussed.
