The clinical, genetic, and neuroradiologic characteristics of dentatorubral-pallidoluysian atrophy (DRPLA) are delineated in six patients from three generations of a Japanese family. The clinical characteristics of the disease varied, the age at onset depending on patients with juvenile-onset were characterized by myoclonus, epilepsy, and mental retardation(More)
A 36 year old man with a history of testicular germ cell tumour presented six months after bilateral orchidectomy with progressive amnesia, irritability, vertical gaze palsy, and generalised seizures. Eight months after initial onset of symptoms, he demonstrated a head drop with muscular atrophy of the upper limbs, shoulder girdle, and posterior neck. He(More)
Auditory and visual cognitive event-related potentials (ERPs) were investigated in 14 patients with HTLV-1 associated myelopathy (HAM) and in 36 normal controls. In the HAM patients, the latencies of P300 and N200 by the auditory tone method were significantly delayed, and N100 by the auditory click method was significantly delayed in latency. No abnormal(More)
A new method of discriminating pathological cerebral atrophy from physiological atrophy during aging is reported. The authors advocate a pixel counting method using a minicomputer for the quantitative measurement of cerebral atrophy. Five hundred cases were studied with this quantitative method and the normal range of the physiological atrophy was(More)
Alectinib, a novel alternative anaplastic lymphoma kinase (ALK) inhibitor, is highly effective against ALK-positive non-small cell lung cancer (NSCLC) and is well tolerated. Molecular targeted agents generally have little contribution to alopecia. We encountered a case of alopecia that developed gradually over 2 months after initiation of alectinib(More)
Little information is available about the usefulness of concurrent chemoradiotherapy for locally advanced thymic carcinoma due to a rare anterior mediastinal tumor. We experienced a case of locally advanced thymic carcinoma that responded well to concurrent thoracic radiotherapy combined with cisplatin plus vinorelbine chemotherapy. The patient showed(More)
BACKGROUND It is shown that low-dose computed tomography (CT) screening is useful for a reduction in lung-cancer-specific mortality in heavy smokers. However, the information about effectiveness according to the histological types of lung cancer has not been adequately investigated especially small cell lung cancer (SCLC). The present study was performed to(More)
To study the cognitive function in 13 patients with sequelae of subacute myelo-optico-neuropathy (SMON), event-related potentials (ERPs) were elicited with tones, clicks, and colored visual stimuli in different tasks. P300 latency was delayed, and P300 amplitude reduced or absent in 5 patients (38%), although neuropsychological assessment for dementia did(More)
Cognitive potential using two-tone auditory discrimination task has been widely used as a standard and useful test to quantify the severity of cognitive dysfunction. According to our experience, however, this method (the T method), sometimes cannot be performed even in normal elderly subjects because of difficult discrimination between these two different(More)
We reported a case with sequelae of SMON and painful tonic seizure (PTS). The patient was a 50-year-old woman. Onset of SMON was when she was 28 years old. She has been suffering from decreased sensation and dysesthesia below C8 cord level to a severe degree, gait disturbance to a moderate degree and visual disturbance to a slight degree. Since January(More)
