"Non-convulsive" partial status epilepticus (SE) is an important pathologic condition that should be differentiated from cerebral infarction. Herein, we reported 2 patients who had partial SE associated with old infarction in the right parietal lobe. Each patient had 2 episodes of left hemiparesis and hemisensory disturbance without convulsion. On(More)
A 53-year-old right-handed Japanese man had a callosal disconnection syndrome associated with an occlusion of the left pericallosal artery. Computerized tomography scan confirmed a left medial lesion affecting the cingulate gyrus, the paracentral lobule, the precuneus of the left hemisphere, and most probably the corpus callosum. This anterior cerebral(More)
We report a Japanese breath-hold diver (Ama) who presented neurological disorders after diving. He repeated diving into 25-30 meters depth in the sea for 6 hours. After diving, he felt dizziness and unsteady gait. Neurological examination showed left quadrant hemianopia, bilateral limb ataxia and ataxic gait. Head CT revealed gas bubbles in the left(More)
UNLABELLED Abstract BACKGROUND AND PURPOSE Patients with severe intracranial hemorrhage (ICH) often develop infectious complications during the acute stage. Animal experiments have demonstrated that enteral immunonutrition with a dietary fluid containing whey peptide (WP) enhances immunoactivity and prevents infection. The aim of the current study was to(More)
A 60-year-old man was admitted to our hospital complaining of fever, headache and vertigo. Neurological examination on admission showed mild ataxic gait. Brain magnetic resonance imaging showed linear high intensity in the left parietal lobe on diffusion-weighted imaging (DWI) and laboratory data revealed elevated serum lactate dehydrogenase and soluble(More)
A 40-year-old man who presented with left hemiparesis was admitted to our hospital. He had tachycardia and a fever. He had a 25-year history of insulin therapy for diabetes mellitus. Brain magnetic resonance (MR) images showed fresh infarction in the right hemisphere, and carotid ultrasonography showed stenosis of the right internal carotid artery (ICA). We(More)
The mechanism of cerebral decompression sickness (DCS) is still unclear. We report 2 cases of breath-hold divers with cerebral DCS in whom magnetic resonance imaging (MRI) demonstrated distinctive characteristics. One case presented right hemiparesthesia, diplopia, and gait disturbance after breath-hold diving into the sea at a depth of 20 m. Brain MRI with(More)
Ulcerative colitis (UC) is a chronic inflammatory bowel disorder that mainly affects the colon and rectum. Immunological derangements are associated with the pathogenesis of UC. Many patients with UC also have chronic kidney disease, associated with immunological disorders and/or pharmacotherapy for UC. Some patients with UC may develop end-stage renal(More)
BACKGROUND Cerebral hyperperfusion after carotid endarterectomy (CEA) is defined as an increase in ipsilateral cerebral blood flow (CBF). Practically, however, prompt and precise assessment of cerebral hyperperfusion is difficult because of limitations in the methodology of CBF measurement during the perioperative period. Arterial spin labeling (ASL) is a(More)
PURPOSE We tested the hypothesis that patients with carotid pseudo-occlusion (PO) have a different prognosis from those with carotid artery stenosis (CS) without PO. MATERIALS AND METHODS 500 patients were examined for CS by cerebral angiography; those with severe CS ≥ 70% (CS group) or with PO (PO group) were enrolled in this study. The primary endpoint(More)
