Two cases of pontine and extrapontine myelinolysis following electrolyte derangements are presented. One case showed only extrapontine myelinolytic lesions on magnetic resonance (MR) imaging, although both pontine and extrapontine myelinolysis were confirmed at postmortem. Another case made full recovery clinically with resolution of extrapontine lesions on… (More)
Human T-cell lymphotropic virus type I (HTLV-I)-associated myelopathy (HAM) and tropical spastic paraparesis belong to a new group of neurological diseases associated with retroviral infection. An HTLV-I-like virus has recently been implicated in multiple sclerosis as well. We studied paired cerebrospinal fluid and serum specimens from HAM and multiple… (More)
An autopsy case of Shy-Drager syndrome preceded by urinary disturbance for over 20 years was reported. A 43-year-old woman was admitted to our hospital because of urinary disturbance and orthostatic hypotension. At the age of 19 she developed urinary disturbance with polyuria and retention. These symptoms were getting worse with years, and at the age of 33… (More)
We analyzed the clinical features of multiple sclerosis (MS) prospectively seen between July 1986 and October 1989 on Hokkaido island, the northernmost part of Japan. Clinical features were generally considered to be intermediate between the previous Japanese reports and those of Western countries. Devic's disease was rare and simultaneous bilateral visual… (More)
A case of neuro-Behçet disease presenting the signs and symptoms of brain stem involvement was diagnosed with magnetic resonance imaging (MRI), while a CT scan failed to show any abnormalities. These abnormal MRI foci were resolved in accordance with neurologic improvements by means of prednisolone therapy.
A 20-year-old man with typical features of Devic disease was studied with magnetic resonance (MR) demonstrating sequential changes of the spinal cord from swelling to atrophy. A good correlation between neurological findings and MR imaging was documented.
We have developed a portable device for formaldehyde monitoring with both high sensitivity and high temporal resolution, and carried out indoor air formaldehyde concentration analysis. The absorbance difference of the sensor element was measured in the monitoring device at regular intervals of, for example, one hour or 30 min, and the result was converted… (More)
We have developed a sensor element for detecting formaldehyde. The sensor element is made of porous glass impregnated with both beta-diketone and ammonium ions. We used three kinds of beta-diketone; acetylacetone, 1-phenyl-1,3-butanedione, and 1,3-diphenyl-1,3-propanedione. The three kinds of sensor element, which are initially colorless, turn yellow after… (More)
UNLABELLED We undertook this to determine the formaldehyde concentration in Japanese houses and the relationship between formaldehyde levels and the age and temperature of a house using a sensor element that we developed for time-integrated measurements of formaldehyde concentration in actual environments. We evaluated the correlation between the… (More)
