[Acute and subacute intracranial hepatoma with hemophilia A--two cases report (author's transl)].

Two cases of traumatic intracerebral hemorrhage in hemophiliac are presented. Case 1 was a 3-year-old boy, who had a mild trauma and became semicomatous. The carotid angiogram showed the findings of intracerebral hematoma and extravasation of contrast medium from the temporal branch of the middle cerebral artery. Evacuation of hematoma was successfully performed under human AHF administration. Postoperatively, the human AHF was administrated to maintain 30% of the plasma concentration of the VIII factor for 3 weeks. He discharged without any neurological deficit. Case 2 was a 14-year-old boy who had experienced several episodes of hemorrhage in nose and knee joints. He had a minor head trauma. Then, 12 days later, he became drowsy and the left hemiparesis developed. The right carotid angiogram revealed the presence of thin subdural hematoma and intracerebral hematoma. From clinical state, however, the conservative treatment was selected and human AHF was administered. The concentration of plasma VIII factor was kept in 30% with human AHF for 2 weeks like case 1. He completely recovered. The authors believe that the human AHF is very effective and 30% of plasma VIII factor is enough for treatment of intracerebral hemorrhage in hemophiliac.

[Radiation therapy and surgical management of pineal tumors--follow-up study of 96 patients (author's transl)].

This is a follow-up study of 96 patients with pineal tumors, except for one patient who was lost to follow-up. 60 of these tumors were verified histologically either at operation or at necropsy, 6 were diagnosed by epitheloid cells existing in the cerebrospinal fluid, and 30 were diagnosed by clinical and ventriculographic findings. In agreement with Russell and Rubinstein, we have classified the histologically verified tumors into 3 groups, as follows; 1. True Pinealoma Group (Pineocytoma, Pineoblastoma), 2. Germinoma-Teratoma Group, 3. Others (Glioma, Cyst). The following points need to be emphasized in the planning of management: 1. Pinealoma (Two cell pattern pinealoma) responds favorably to radiation therapy. 18 of 43 patients of pinealomas who were treated with irradiation are functioning normally in various life situations for more than 5 years. Among them, 5 cases of pinealomas treated with irradiation alone have more than 10 years survivals. 2. There is a limitation in the efficacy of irradiation therapy in cases of spinal cord implantation, infiltration in adjacent structures or subependymal infiltration along the ventricular cavity. 3. Only 2 of 67 patients with pinealomas had spinal cord metastasis. It seems undesirable to subject all patients to complete cerebrospinal axis irradiation. 4. Successful removal were performed in 4 patients with teratomas and are now alive for 9-21 years. None of them, however, are doing well clinically with many neurological deficits. 5. Since adenocarcinoma, teratocarcinoma, teratoblastoma and others are not sensitive to radiation therapy, only the palliative treatments are available. 6. Therefore, the most promising treatments for pineal tumors is that irradiation, plus shunting operation when required, is a first choice and after irradiation, radical removal should be tried in the case of teratoma diagnosed by clinical and ventriculographic findings.
