The aim of the present study was to examine the changes of inflammatory and coagulation factors in blood of the internal jugular vein, not of peripheral vein, in patients with subarachnoid hemorrhage (SAH). The results show that while interleukin-6 (IL-6) and platelet activating factor (PAF) concentrations increased within first 4 days after SAH and(More)
This report describes a preoperative simulation and intraoperative localization system for use with three-dimensional functional images in intracranial surgery. The system, which produces three-dimensional functional images by superimposition of the generators of somatosensory evoked potentials derived from dipole tracing, was applied in the preoperative(More)
Brain temperature was measured at various depths beneath the pial surface in patients with hydrocephalus of varying aetiology. Temperature increased gradually with depth in all patients, with the highest temperature found in the ventricle. The difference between intraventricular and rectal temperatures (delta v-r) was greater in patients who underwent(More)
Moyamoya formations at the base of the brain are not congenital vascular malformations but represent collateral pathways associated with chronic progressive stenosis of the carotid fork. The authors have studied 44 personal cases, 18 children under 15 years of age, and 26 adults. In children the Moyamoya vessels change through six stages: (1) carotid fork(More)
A case is reported of acoustic neurinoma unrelated to Von Recklinghausens' disease in a child. A 14-year-old boy had suddenly become aware of impaired hearing associated with tinnitus, in August, 1988. He was admitted to our department in October, 1988. On admission, he had no neurological deficits except for right tinnitus. Acoustic tumor was found on air(More)
PURPOSE Atherothrombotic occlusion of the cervical internal carotid artery (ICA) without collateral flow is one of the most critical forms of acute ischemia. We report the results of urgent thrombolytic treatment of patients with major stroke in this clinical category. METHODS Clinical findings and outcome in 33 patients were investigated. All patients(More)
OBJECT The goal of this study was to evaluate the efficacy of direct packing of the isolated sinus (occluded both distally and proximally) in patients with dural arteriovenous fistulas (AVFs) of the transverse-sigmoid sinus. METHODS Eight patients were included in this study. There were seven men and one woman, ranging in age from 47 to 75 years (mean(More)
It is well known that Down's syndrome is sometimes associated with leukemia. However, there have been only a few case reports of a relationship between Down's syndrome and brain tumors. We report 2 cases with histological diagnoses of germinoma. The 1st case was a 10-year-old boy with Down's syndrome complaining of seizure and left hemiparesis. Computed(More)
OBJECT It has been suggested that nuclear factor (NF)-kappaB, a pleiotropic transcription factor, controls cell proliferation. The authors examined NF-kappaB activity and its participation in the growth of human malignant astrocytoma. METHODS The authors examined NF-kappaB activity in human malignant astrocytoma cell lines and high-grade astrocytoma(More)
