Surface electromyography was performed for both heads of the biceps brachii in 11 healthy men while the muscles were under 30% maximum isometric shoulder flexion and abduction. Elbow related biceps activity was minimized by using a brace locked in neutral forearm rotation. Electromyographic activity was normalized as a percentage of maximal muscle(More)
OBJECTIVE To clarify the role of the T-lymphocyte-associated-4 (CTLA-4) polymorphism in the susceptibility to child-onset type 1 diabetes with regard to its clinical characteristics and complications with autoimmune thyroid disease (AITD) in the Japanese population. RESEARCH DESIGN AND METHODS The CTLA-4 49 A/G polymorphism was detected by the(More)
A 39-year-old man was admitted with right hearing loss, tinnitus and vertigo. Neurological examination on admission revealed right facial palsy, right acoustic nerve disturbance and cerebellar ataxia. CT scan demonstrated a mass with intra-and extracranial extension in the pyramid bone concomitant with enlarged jugular foramen. MRI showed a ring-like(More)
BACKGROUND The purpose of this study was to clarify the pathologic features and clinical significance of the meningeal enhancement surrounding meningiomas ("flare sign") on contrast-enhanced T1-weighted magnetic resonance images (MRI). METHODS The marginal dura mater of tumors was resected from nine cases of meningioma exhibiting a flare sign and used for(More)
A 42-year-old female was admitted to our department on 3 August, 1993 with a 3-month history of steadily enlarging subgaleal mass (3.2 x 3.0 cm) in the parietal region. She had been doing well following radiotherapy for cervical carcinoma of the uterus one year previously. Neurological examination on admission was negative. Axial T1-weighted MR images(More)
BACKGROUND The development of systemic metastases from primary intracranial gliomas is rare. We report here a rare case of pontine glioma with osteoblastic skeletal metastases. CASE This 12-year-old boy presented with a 4-month history of hoarseness, dysphagia, and a progressively ataxic gait. Cranial computed tomography (CT) and magnetic resonance(More)
To assess the gait characteristics of the patients with coxarthrosis objectively, the rotation of the pelvis during ambulation was measured on the frontal, sagittal and horizontal planes using 3 gas-rate-sensors(Rotational Angle Measurement System G-2210, Anima Inc., Tokyo). In the normal subjects, the waveforms of the rotational angle on the frontal plane(More)
