High dose ACNU and radiation therapy with autologous bone marrow rescue was performed in a 3-year-old boy suffering from cerebellar medulloblastoma, whose main mass had been removed at operation when widespread subarachnoid tumor dissemination was already present. The myelosuppression, which is a major side effect of high dose chemotherapy, was successfully prevented by the autologous bone marrow grafting and the serial CT scans showed complete disappearance of the tumor. ⋯ Although the autologous bone marrow rescue therapy is a technical advance to cope with myelosuppression secondary to chemotherapy, side effects of the other organs, particularly of the respiratory system, remain to be solved. The optimal treatment schedule should be established as soon as possible.

One hundred fourteen patients with ruptured cerebral aneurysms were reviewed in regard to the incidence and etiological factors of preoperative disturbances of water and electrolyte metabolism. Patients with inadequate salt intake, evidence of renal disease, cardiac failure or excessive diuretic therapy were excluded. Twenty-five (21.9%) patients developed water and electrolyte disturbances. ⋯ The patients in grade III, IV according to Hunt & Hess. The patients with high density in the basal subarachnoid space on the CT scan. The patients with a small hematoma in the region of the basal frontal interhemispheric fissure in cases with aneurysms of the anterior communicating or anterior cerebral artery.(ABSTRACT TRUNCATED AT 250 WORDS)
