Pachymeningoencephalitis: case report.

Hypertrophic cranial pachymeningitis is uncommon. We report the first case of pachymeningitis extending to the cerebral parenchyma (pachymeningoencephalitis) and involving the bone and extracranial soft tissue. The clinical features and pathogenesis are discussed.

Radiotherapy after hyperbaric oxygenation for malignant gliomas: a pilot study.

The results of radiotherapy combined with hyperbaric oxygen in 9 patients with malignant glioma were compared with those of radiotherapy without hyperbaric O2 in 12 patients. This is the first report of a pilot study of irradiation immediately after exposure to hyperbaric O2 in humans. All patients receiving this treatment showed more than 50% regression of the tumor, and in 4 of them, the tumors disappeared completely. Only 4 out of 12 patients without hyperbaric O2 showed decreases in tumor size, and all 12 patients died within 36 months. So far, this new regimen seems to be a useful form of radiotherapy for malignant gliomas.

頭蓋内疾患における聴性脳幹反応（ABR）の検討

In 47 cases with intracranial lesions, auditory brainstem responses (ABRS) were studied. From a detailed analysis of these data, the following results were concluded: In some cases, the intramedullary and extramedullary pontine tumor could be differentiated by ABR, A very small cerebello-pontine angle tumor was detected by ABR, ABR monitering was useful to evaluate brainstem function during the surgical operation, and ABRS were clinically very useful methods for predicting the outcome of a severe head injury and diagnosis of brain death. These results indicate that ABRS contribute to functional diagnosis of various diseases of the central nervous system.
