We assessed the accuracy of voxel-based morphometry (VBM) using a three-dimensional T1-weighted MRI in discriminating Alzheimer's disease (AD) in the very early stage of amnestic type of mild cognitive impairment and age-matched healthy controls. We randomly divided these subjects into two groups. The first group comprising 30 AD patients and 41 controls(More)
BACKGROUND we investigated the clinical efficacy of intra-arterial administration of fasudil hydrochloride for cerebral vasospasm. METHOD we reviewed 90 cases treated with intra-arterial administration of fasudil hydrochloride between August 1998 and April 2009 and investigated the clinical efficacy for cerebral vasospasm. FINDINGS angiographic(More)
There have been very few reports in Japan of patients with allergic fungal sinusitis (AFS). We describe two cases caused by Bipolaris spicifera and Schizophyllum commune. The patients were a 70-year-old male (Case 1) and a 55-year-old female (Case 2). Both presented with nasal obstruction and purulent nasal discharge. CT scans revealed each to have a soft(More)
A 46-year-old Japanese woman underwent a right lower lobectomy through a posterolateral incision made in the fifth intercostal space under general and epidural anesthesia on January 23, 1995. During the procedure, oxidized regenerated cellulose (Surgicel) was used to prevent postoperative rebleeding from the dorsal branch of the fifth intercostal artery.(More)
The cerebral circulatory dynamics were evaluated before and after intra-arterial administration of fasudil hydrochloride in 20 patients with angiographic vasospasm after subarachnoid hemorrhage (SAH). The region of interest time-density curves obtained before and after intra-arterial administration of fasudil hydrochloride were compared in the proximal(More)
Low-intensity pulsed ultrasound (LIPUS) stimulation has been shown to effect differentiation and activation of human chondrocytes. A study involving stimulation of rabbit disc cells with LIPUS revealed upregulation of cell proliferation and proteoglycan (PG) synthesis. However, the effect of LIPUS on human nucleus pulposus cells has not been investigated.(More)
As methods of cancer diagnosis and treatment improve, interest in metastatic brain tumors continues to increase. In the present study, we attempted to characterize genetically the dynamic changes occurring during brain metastasis formation by DNA microarray, and attempted to compare these findings with histological observations. Lewis lung carcinoma cells(More)
Decerebrate spasm is a generalized muscular spasm produced by some stimuli on decerebrate posture. Such spasm are called "tonic fit" or "decerebrate extensor spasm". We reported a 50-year-old man with periodic decerebrate spasm after cerebral hemorrhage. On admission, the patient was comatose. The pupils were round but anisocoric and did not react to light.(More)
We have designed a screening system to diagnose unruptured aneurysms, including the use of digital subtraction angiography (DSA). We surveyed 115 patients who had undergone clipping procedures after subarachnoid hemorrhage (SAH) and questioned them with regard to the subjective symptoms. Sixty-eight of 92 patients who returned the questionnaire reported,(More)
