OBJECTIVE The precise etiology of perimesencephalic nonaneurysmal subarachnoid hemorrhage (P-SAH) has not yet been determined. We decided to compare the venograms of patients with P-SAH with those of patients with aneurysmal SAH (A-SAH) to examine the relationship between P-SAH and venous drainage patterns. METHODS We retrospectively studied 18 patients(More)
The cardiopulmonary effects of sevoflurane (mean, 2.6, 3.8-3.9 and 5.2 per cent) were compared with those of halothane (1.2, 1.8 and 2.4 per cent), enflurane (2.4, 3.6 and 4.8 per cent) and isoflurane (1.6, 2.4 and 3.2-3.3 per cent) at end-tidal concentrations equivalent to 1, 1.5 and 2 minimal alveolar concentrations (MACs) during spontaneous or controlled(More)
The monocyte chemotactic protein 3 (MCP-3) belongs to the MCP subgroup of the CC chemokines and promotes chemotaxis of immune cells. MCP-1 is believed to play an important role in monocyte infiltration into tumor tissues; however, the relationship between tumor-infiltrating macrophage/microglia (TIM/M) and the expression of chemokines has not been(More)
We report a very rare case of hemangioblastomatosis in a patient without von Hippel–Lindau disease (VHL). A 50-year-old woman had a history of surgical procedures for total removal of a cerebellar hemangioblastoma (HB). Twenty-one years after the last operation, she developed communicating hydrocephalus; computed tomographic (CT) scans of the brain showed(More)
The objective of this study was to investigate the factors that potentially lead to brain radionecrosis (RN) after micromultileaf collimator-based stereotactic radiosurgery (SRS) for brain metastases. We retrospectively evaluated 131 lesions with a minimum follow-up of 6 months, 43.5% of which received prior whole-brain radiotherapy (WBRT). The three-tiered(More)
A retrospective study of 75 patients treated surgically for ruptured middle cerebral artery (MCA) aneurysm within 48 hours evaluated clinical grade at admission, secondary development and management of cerebral swelling associated with space-occupying hematoma, cerebral infarction caused by vasospasm, development of hydrocephalus, and clinical outcome.(More)
It is well known that tumor necrosis factor (TNF) can have both contrary and pleiotropic effects in anti-tumor immune response. In the present study, we prepared two different tumor cell-based immunotherapy models: MCA38 adenocarcinoma and GL261 glioma intracranial interleukin-2 (IL-2)-based. Each tumor was transfected to express IL-2 with or without(More)
A 32-year-old woman underwent surgeries and radiation therapy for astrocytoma. She developed symptomatic radiation necrosis in the lesion, which caused hydrocephalus. She initially underwent ventricular drainage, because the protein level in the cerebrospinal fluid (CSF) was 787 mg/dL, which was too high for shunt surgery. Because she also had breast(More)
