Comparative Study
Cross-cultural adaptation and validation of multiple sclerosis quality of life questionnaire (MSQOL-54) in a Turkish multiple sclerosis sample.
Multiple sclerosis (MS) is a chronic progressive disease with multiple neurological impairments. The disease can also dramatically affect the health-related quality of life of patients. The objective of this study was to investigate the validation of the translated and cross-culturally adapted MSQOL-54 in 183 Turkish MS patients. ⋯ Assessment of quality of life of MS patients in addition to disease severity and disability level is important, because it provides unique information that is important to patients and to clinicians. A translation of an existing MS-targeted HRQOL measure from US English into Turkish was easily administered and well accepted in a Turkish MS sample.

Increased serum-GFAP in patients with severe traumatic brain injury is related to outcome.
Several studies have established the relevance of S-100 in blood as a marker of brain damage after traumatic brain injury. However, a more specific marker is required and glial fibrillary acidic protein (GFAP) is considered to be a good candidate. ⋯ Serum-GFAP is increased during the first days after a severe traumatic brain injury and related to clinical outcome.

Impaired myocardial 123I-metaiodobenzylguanidine uptake in Lewy body disease: comparison between dementia with Lewy bodies and Parkinson's disease.
Iodine-123-labeled metaiodobenzylguanidine (123I-MIBG) myocardial scintigraphy has been used to evaluate cardiac sympathetic denervation in Lewy body disease (LBD) including Parkinson's disease (PD) and dementia with Lewy bodies (DLB). Patients with LBD had marked reductions in cardiac MIBG accumulation, indicative of severe impairment of the cardiac sympathetic nervous systems. However, the differences in scintigraphy between DLB and PD have not been determined. ⋯ Our findings suggest that cardiac sympathetic function in DLB is severely impaired even in the early disease stage.

The relearning of daily activities after stroke also involves performance of bimanual tasks. This raises the possibility that concurrent activation of the healthy hemisphere interferes with reorganization processes in the affected hemisphere due to inhibitory pathways between homologous motor cortex representations. This study investigated the effect of voluntary, simultaneous activation of both hands upon the non-dominant (healthy subjects) or affected (stroke patients) hemisphere. ⋯ In healthy subjects voluntary activation of the ipsilateral hand does not change the excitability of the motor cortex of the non-dominant hemisphere, when the contralateral hand is simultaneously activated. The facilitation of the contralateral hand seems to gate further facilitation by the ipsilateral hand. However, in stroke patients simultaneous activation of both hands causes an additional facilitation compared to activation of the affected hand alone.

The hereditary spinocerebellar ataxias (SCAs) are a clinically and genetically heterogeneous group of neurodegenerative disorders. The genes causing 11 of these diseases have been identified. To date, there is no report of SCA type 6 (SCA6) in Mainland Chinese. ⋯ Among the 60 patients with sporadic ataxias in the present series, 3 (5.0%) were found to harbor SCA3 mutations, whereas none were found to harbor SCA6 mutations. In the 4 families with SCA6, we found significant anticipation in the absence of genetic instability on transmission. This is the first report of geographic cluster of families with SCA6 subtype in Mainland China.
