Résumé
BACKGROUND: Age is one of the many factors that can influence functional improvement and activities of daily living (ADL) after a stroke. We looked at the effects of functional improvement of hemiplegic upper extremity (HUE) on ADL according to age in stroke patients. METHODS: We recruited 46 stroke patients beginning acute or subacute rehabilitation. They were classified into two groups according to age, the elderly group (> or =65 years, n=18) and the young group (0.05). There were no significant differences in the changes to Pedretti clinical test, MFT, and FIM between the two groups before and after rehabilitation (p>0.05). In the young group, the motor improvement of HUE correlated significantly with FIM (p0.05). CONCLUSION: In our study, elderly stroke patients showed improvement in function and ADL similar to young stroke patients. This potential should be maximized and elderly stroke patients should receive active rehabilitation.

A 53-year-old man abruptly developed headache and unconsciousness. Brain computed tomography (CT) and CT angiography showed subarachnoid hemorrhage, intraventricular hemorrhage, and multiple tortuous vascular structures on the brain stem and upper cervical spinal cord. Four-vessel angiography displayed intradural ventral arteriovenous fistula, supplied by the left vertebral and occipital arteries. Drainage was via both sigmoid sinus and cervical venous plexus. He had been treated with transarterial coil embolization of the left vertebral artery. Subsequently, he suffered from left hemiplegia and cognitive problem. Brain magnetic resonance (MR) and MR angiography performed 4 weeks later revealed multiple infarctions on the left cerebellum, left upper cervical spinal cord, and both medial thalamus, as well as occlusion of the left vertebral artery with reduction in varix size. After rehabilitative management, his muscle strength and cognitive function improved. We report a very rare case of dural arteriovenous fistula on the brain stem and upper cervical spinal cord.

OBJECTIVE: To investigate the effect of regular exercise program on cognitive function in chronic cerebral hypoperfused rat. METHOD: Forty-eight male Sprague-Dawley rats were used. Chronic cerebral hypoperfusion was induced by bilateral common carotid arteries occlusion (BCCAO). All rats were randomly divided into 4 groups: normal rats (group A); normal rats with regular exercise program (group B); BCCAO rats (group C); BCCAO rats with regular exercise program (group D). Regular exercise program was composed of daily 30-minute treadmill exercise for 4 weeks. Cognitive function was evaluated by Morris water maze (MWM) test. The activities of superoxide dismutase (SOD) and the level of malondialdehyde (MDA) were checked. The neurons were microscopically analyzed on Hematoxylin-Eosin and Cresyl violet stains. RESULTS: After regular exercise program, there was significant difference in the escape latency among 4 groups in hidden platform trial of MWM test (p<0.05). There was significant difference in the number of crossings among 4 groups in probe trial of MWM test (p<0.05). The activities of SOD of group A and group D were significantly higher than those of group C, respectively (p<0.05). Histopathological study displayed the formation of apoptotic cell bodies and pyknotic cells in group C and group D. There were more normal neurons in group D than group C. CONCLUSION: Regular treadmill exercise was helpful in improving cognitive function in chronic cerebral hypoperfused rat. Therefore, regular exercise program would be one of the useful strategies for treating chronic neurodegenerative diseases.

A 49-year-old man received prolotherapy in the upper cervical region at a local medical clinic. Immediately after the procedure, he felt a sensation resembling an electric shock in his right upper and lower extremities, and continuously complained of numbness and discomfort in the right hemibody. He visited our clinic a week later. Upon physical examination, there were no significant abnormal findings. The visual analog scale was 60 points. T2-weight magnetic resonance images of the cervical spine showed a 0.7 cm sized bright oval spot on the right side of the spinal cord at the level of C4-C5 disc, suggesting spinal cord injury. There were no definite electrodiagnostic abnormalities. Digital infrared thermal images showed moderately decreased surface temperature on lateral aspect of the right forearm and dorsum of the right hand compared with the other side. Considering that very rare complications like spinal cord injury may develop after prolotherapy, we suggest that special interventions such as prolotherapy be performed by professional experts.
