We determined the oxidative phenotype and metabolic ratio of debrisoquine in 96 Chinese patients with Alzheimer's disease (n = 12), Parkinson's disease (n = 55), and using patients with stroke and cervical spondylosis as controls (n = 29). We did not find any difference in debrisoquine metabolic phenotype among Parkinson's disease, Alzheimer's disease, and control patients as judged by chi-square analysis. In addition, the metabolic ratio of all our patients was less than 12.6. The result suggested that Chinese patients with Parkinson's disease and Alzheimer's disease metabolize debrisoquine at a velocity not different from that of their Western counterparts even though the frequency distribution of debrisoquine metabolism phenotyping in these two populations is quite different.

An 81-year-old man with Parkinson's disease was admitted to our hospital with impaired function of all extremities. Four weeks before his symptoms developed, he had tripped on the steps, fallen and bruised his jaw. Following this episode he experienced a few more falls inside his house. On examination his greatest weakness was in the hands and wrists. He was hyper-reflexic in all extremities and had bilateral Babinski's sign. He could not walk and needed physical assistance in most of his daily living activities. X-ray films of the cervical spine showed significant degenerative changes. The magnetic resonance images suggested central cervical cord damage at the level of the C6 vertebral body. After three months' rehabilitation treatment, he became able to walk with a cane and became independent in all the basic activities of daily living except for bathing. He never regained skillful function of his hands despite later levodopa treatment of Parkinson's disease. His clinical features were consistent with the central cervical cord syndrome, described by Schnneider and co-workers in 1954. This syndrome may occur as a result of hyperextension neck injury, occasionally associated with an accidental fall in the elderly with cervical spondylosis. Thirteen patients with cervical spinal cord injury above 65 of age were admitted to our department from 1983 to 1993. Six of them presented with the central cervical cord syndrome, and all patients had a history of accidental injuries related to falling.

Plasma and CSF levels of C4d and the circulating immune complex (CIC) to C1q were measured in 27 patients with progressive supranuclear palsy (PSP), Parkinson's disease (PD) and cervical spondylosis (CS). There was no significant difference among groups in plasma C4d or in plasma or CSF CIC to C1q. However, the PSP group had significantly higher CSF levels of C4d than the PD and CS groups. Higher CSF C4d index in the PSP group was also shown compared with PD and CS groups. These results suggest that augmented complement activation in the wide areas of the central nervous system occurs in PSP. CSF levels of C4d or C4d index may serve as a basis for differentiating PSP from PD.

We measured the concentration of neural thread protein (NTP) in cerebrospinal fluid (CSF) by an automatized microparticle enzyme immunoassay from 11 progressive supranuclear palsy (PSP) patients and 11 Parkinson's disease (PD) patients and 7 patients with cervical spondylosis as controls. The mean levels did not differ significantly among the groups. In the PSP group, however, the levels correlated significantly with the severity of motor symptoms, signs and functional disability but not with dementia, while the opposite was true in the PD group. The elevated levels in PSP cases may reflect an increase with progression of the disease in such pathological structures as neurofibrillary tangles or neuropil threads, while in PD such levels may indicate associated Alzheimer-type pathology.

Although the subspeciality of movement disorders was established in neurology more than 20 years ago, it is relatively new in Thailand, and while most physicians are generally aware of Parkinson's disease, they often are not familiar with dystonia. As one of the common movement disorders seen in general practice, a number of family and population studies have suggested that as many as two-thirds of patients with dystonia may be underdiagnosed and it is likely that misdiagnosis occurs frequently. Moreover, there is little information on the prevalence of dystonia in Thailand. The purpose of this study was to determine the prevalence and clinical profile of dystonia among Thai patients who came from the southern part of Bangkok, which is in the catchment area of Chulalongkorn University Hospital. In addition, the diagnostic accuracy of dystonia among referred patients was assessed. The medical records of 207 patients were reviewed and it was determined that a large proportion of them (71.9%) had focal dystonia with cervical dystonia being the most common form. Primary dystonia (68.1%) accounted for the majority of the cases. The prevalence of all forms of dystonia, primary dystonia and focal dystonia was 19.9, 13.6 and 14.3 per 100,000 persons, respectively. The diagnostic accuracy of dystonia among referred patients was 85.5%. The most common misdiagnosis was cervical spondylosis, followed by myofascial pain syndrome. Most patients had an average disease duration of 4 years before dystonia was finally diagnosed. Most patients with focal dystonia responded well to botulinum toxin therapy, with 13.3% suffering only mild transient adverse events. In spite of the limitations of this study, this data will initiate a process of increasing both patient and professional awareness of dystonia in Thailand.

Dropped head syndrome is seen in various diseases. We investigated its pathophysiological mechanisms with physical and radiological examination, surface EMG and responses to physiotherapy. Subjects had dropped head as a complaint, but their primary diagnoses were various. We investigated 16 cases: 5 cases of Parkinson disease, 5 cases of multiple system atrophy predominant parkinsonism, 3 cases of cervical spondylosis and 3 cases with other diagnoses. We found that patients had common findings such as bulging of cervical muscles, and tonic EMG activities mainly in the extensors in the sitting and standing position, but in the flexors of the neck only in the supine position. Of the 16 cases, 14 were treated with physiotherapy to improve the alignment of the pelvis and whole vertebral column; 6 of the 14 cases (63%) showed remarkable improvement. We conclude that the primary reason of dropped head syndrome is unknown in Parkinson disease and cervical spondylosis, but also that many of the patients have secondary changes in alignment of the skeletomuscular system which could be treated with physiotherapy.

Recent case reports suggest a possible causal correlation between antecollis and pramipexole. Here, we report the case of a 62-year-old Italian man with a 2-year history of Parkinson's disease (PD) and cervical spondylosis for which he was treated with pramipexole. He developed severe neck rigidity immediately after an inguinal hernia operation but several months after introduction of pramipexole. He was initially treated with painkillers and physiotherapy with no significant improvement. His condition deteriorated presenting disproportionate rigidity between anterior and posterior neck muscles (antecollis) to the extent that normal activities were severely restricted. However, significant improvement occurred after the withdrawal of pramipexole. The patient undertook a second cycle of physiotherapy with remarkable results and returned to function normally in everyday life. This case report suggests that neurologists should be motivated to inform the scientific community about other possible cases in which an association between antecollis and pramipexole might operate in PD.
