An autopsy case of pure akinesia (PA) is reported. The patient manifested L-dopa-unresponsive akinesia without accompanying rigidity, tremor, eye movement disorder or dementia from the age of 58 years. Brain magnetic resonance T2-weighted imaging at the age of 63 showed high intensity areas in the subthalamic regions, but brain atrophy was not observed. She received amantadine-HCl and L-threo-3,4-dihydroxyphenylserine (L-DOPS) for 5 years. At the age of 66, she died of the severe illness accompanied by consciousness disturbances, hyperthermia, muscle rigidity, abnormal blood pressure and elevated serum enzymes which were derived from the muscle. We considered her condition to be neuroleptic malignant syndrome (NMS). Pathologically the brain revealed degeneration in the subthalamic nucleus, globus pallidus and substantia nigra. Neurofibrillary tangles were detected in the temporal cortex, hippocampus, amygdaloid body and spinal cord, as well as in the basal ganglia, thalamus and brain stem. These findings were consistent with that of progressive supranuclear palsy (PSP); the change in the ventral pons was insignificant, suggesting that PA may have minimum involvement in the ventral pons. The skeletal muscle showed scattered necrosis that was compatible with NMS. As far as we know, this is the first report of NMS accompanied with PA.

We report a case of Parkinsonism due to interferon alpha (IFN alpha) therapy for chronic hepatitis C. A 51-year-old female received IFN alpha (Sumipheron@6 x 10(6) IU), three times a week by intramuscular injection. Six months after the initiation of IFN alpha therapy, she noticed tremor of bilateral fingers, and was admitted to our hospital. Neurological examination revealed muscle rigidity, bilateral finger tremor, mild bradykinesia. Tremor was more extreme at posture rather than at rest. She was diagnosed as Parkinsonism, and carbidopa-levodopa therapy was effective. Attention must be paid to Parkinsonism, when IFN alpha is administered.

We analyzed patients with Parkinson's disease from various aspects such as clinical findings, the degree of independence in daily life, care environment, quality of life (QOL) and treatment at home. The subjects were 104 in- and outpatients (47 males and 57 females) seen at our hospital. The mean age was 69.85 years in the males and 70.35 years in the females. The disease most frequently developed at the age of 60-69 years and the disease duration was 5 years or more in 52 patients. Rigidity was the most common symptom (91 patients), followed by gait disturbance (n = 87) and tremor (n = 86). Levodopa/carbidopa was the drug most frequently used (77 patients). The number of patients treated by combination drug therapy increased with the duration of disease. Concerning the degree of independence in daily life, assistance was often necessary in bathing, dressing and undressing, toileting and walking. In particular, total assistance was necessary in patients with Hoehn-Yahr stage-IV and V disease. The comprehensive QOL was the lowest in terms of social activities, hobbies and leisure activities, followed in order by work and subjective QOL. QOL decreased in each item with the severity of the disease. Treatment at home was performed for 19 patients, of whom 11 are still being treated by our staff. Treatment at home combined with persons who care for the patient and in cooperation with other welfare resources may improve the patient's QOL. In diseases that require long-term care such as Parkinson's disease, a comprehensive care management system should be established from the aspect of the patient's QOL.

Posteroventral pallidotomy (PVP) has been shown to alleviate motor symptoms in Parkinson's disease (PD), e.g., rigidity, secondary akinesia due to existence of muscle rigidity and slight tremor, but not the marked tremor. For the latter, additional lesion of the ventral intermediate nucleus of the thalamus is necessary. Akinesia was divided into three subtypes, and the influence of PVP on each type is described. Primary akinesia is not changed by either PVP or thalamotomy but responds well to L-dopa. Psychological symptoms, i.e., depressive mood, loss of initiation or abulia, and lowered emotional activity, which are generally termed as bradyphrenia, benefit well from PVP but less from thalamotomy. This effect is interpreted as due to the lesion extending into the ventral pallidum, where a small posterior part of the limbic-motor projections may possibly be involved. Such experience suggests that the third type of akinesia in PD, named the 'psychomotor or limbic-motor type' by the author, can be improved by the surgical procedure on the ventral globus pallidus. These observations offer an important chance to understand the psychological symptoms in PD as a result of dopamine deficiency of ventral tegmental area neurons projecting to the ventral striatum, which further influences the ventral pallidum.

Transplantation of autologous sympathetic ganglion was performed in 35 patients with Parkinson's disease. Approximately half the patients showed improvement of parkinsonian symptoms over the 3 years following transplantation. The patients showed amelioration of bradykinesia and gait disturbance, but tremor and muscle rigidity were not improved by transplantation. The other half of the patients did not show amelioration after transplantation. No serious complications were encountered, though mild ptosis was observed in all patients. The mechanism of improvement of symptoms might be the release of dopamine from the grafted sympathetic ganglion. Transplantation of autologous sympathetic ganglion can be a therapeutic modality for Parkinson's disease.

We report a 74-year-old woman with parkinsonism and dementia, who died 4 years after the onset of the disease. She was well until 70 years of the age (1993) when she noted slowness in the movement in her left hand. She also developed gait disturbance and the similar symptoms spread to the right upper and lower extremities. Two years after the onset, she had difficulty in walk, and was admitted to our hospital on March 9, 1995. Her daughter had the onset of hand tremor at 50 years of the age and gait disturbance at 52. Her gait improved after levodopa treatment, but her MRI revealed a liner T2-high signal lesion along the outer surface of each putamen. On admission, the patient was alert but slighted demented. Higher cerebral functions were normal. She had a masked face and small voice. Her gait was of small step without arm swing. Retropulsion was present. Rigidity was noted in the neck but not in the limbs. She was bradykinetic but tremor was absent. She was treated with levodopa/carbidopa, dops, and bromocriptine with considerable improvement and was discharged on March 30, 1995. On January 19, 1996, she developed fever and hallucination; she became more akinetic and admitted again. She showed marked dementia and stage IV parkinsonism. She was treated by supportive measures with improvement in the general condition, but she was found to have a gastric cancer for which a subtotal gastrectomy was performed on March 11, 1996. Post-operative course was uneventful, but her parkinsonism progressed to stage V. She was transferred to another hospital on May 13, 1996. In July 21, 1996, she developed dyspnea and fever and was admitted to our hospital again. She was somnolent. Rigidity was moderate to marked and she was unable to stand or walk. By supportive cares, her general condition improved and was discharged to home on November 4, 1996. She developed fever on June 13, 1997 and admitted to our service again. Her BP was 150/90 mmHg. She was alert but markedly demented. Laboratory examination revealed increases in liver enzymes (GOT 75 IU/l, GPT 101 IU/l) and renal dysfunction (BUN 68 mg/dl, creatinine 3.27 mg/dl). Subsequent hospital course was complicated by renal failure and thrombocytopenia (33,000/ml). She expired on July 1, 1997. The patient was discussed in a neurologic CPC, and a chief discussant arrived at the conclusion that the patient had diffuse Lewy body disease and her daughter striatonigral degeneration. Some participants thought both the patient and her daughter had diffuse Lewy body disease. Post-mortem examination revealed marked degeneration of the substania nigra and the locus coeruleus. The medial part of the nigra also showed marked cell loss. Lewy bodies were found in the remaining nigral and coeruleus neurons. Cortical Lewy bodies were very few and the striatum was intact. Pathologic diagnosis was Parkinson's disease. Dementia was in part attributed to the marked degeneration of the medial part of the substantia nigra.

With a short description of the historical background, thalamotomy and posteroventral pallidotomy (PVP) are introduced as effective means to alleviate motor symptoms in Parkinson's disease (PD). Rigidity and dopa-induced dyskinesia are improved and abolished by either of the two procedures, but tremor is more markedly improved by thalamotomy than by PVP. To date, surgical treatment has been important in treating PD. Also, the influence of PVP on psychological symptoms in PD, bradyphrenia and emotional changes offers an important key to understand and to interpret these symptoms.

A 49-year-old man was admitted with the chief complaints of muscle weakness and gait disturbance. His neurological examination was compatible with peripheral neuropathy, and laboratory tests revealed IgA monoclonal gammopathy, increased protein content in the cerebrospinal fluid (CSF) without pleocytosis, and slow motor and sensory nerve conduction velocity. He was diagnosed as having chronic inflammatory demyelinating polyneuropathy with IgA monoclonal gammopathy of undetermined significance. The patient was treated with steroid, and plasmapheresis. He became so restless that antidepressant and haloperidol were administered. Then, he became unresponsive, and developed high fever, sweating, tachycardia, and tremor. Examination of CSF showed increased 3-methoxy-4-hydroxy-phenylglycol and decreased homovanillic acid. He was diagnosed as having neuroleptic malignant syndrome (NMS). However, his muscle tonus was still flaccid in his lower extremities that had been suffered from chronic polyneuropathy. Interestingly, his serum creatine kinase (CK) content was only slightly elevated. We suppose that the pathophysiological location of NMS might be primarily central, and that muscle rigidity and elevation of serum CK might not occur, if the peripheral nerves were completely impaired.

The most venomous scorpion species are Buthotus tamulus of India, the Leiurus quinquestriatus and Androctonus crassicauda of North Africa and the Middle East, the Tityus serrulatus of Brazil, and the Centruroides suffussus of Mexico. The severity of scorpion envenomation varies with the scorpion's species, age, and size, and is much greater in children. Systemic intoxication reflects the overstimulation of the CNS, the sympathetic and parasympathetic nervous system. Severity ranges from local pain and paresthesia to fatal cardiotoxicity and encephalopathy. Symptoms include: agitation, tachycardia, vomiting, abdominal pain, salivation, diaphoresis, dehydration, muscle rigidity and twitching, tremor, seizures, coma, pupillary changes, hyperthermia, tachyarrythmias and occasionally bradyarrhythmias, hypertension, and less often hypotension, cardiac failure, and priapism in males. Laboratory abnormalities include: hyperglycemia, leucocytosis, transient elevation of cardiac and pancreatic enzymes, ischemic changes in the ECG, and evidence of cardiac dysfunction on echocardiography. The principles of management are: observation, cardiac monitoring, supportive treatment with intravenous fluids and electrolytes, and a meticulous use of cardiovascular agents: vasodilators, adrenergic antagonists, or calcium channel blockers in the hypertensive phase; and inotropic agents in the event of hypotension. Antiarrhythmics such as lidocaine, may be required. There is increasing evidence for the efficacy of specific antivenom. The advance in supportive care and antivenom efficacy has markedly improved the outcome of patients with scorpion envenomation.

1. We examined 156 patients 33 years after CO poisoning occurred at the Miike Mikawa Mine, Fukuoka, Japan. The subjects were classified according to age as follows: between 55 and 59 years (n = 14), 60 and 69 years (n = 62), 70 and 79 years (n = 60), and 80 and 87 years (n = 18). The mean age was 69.2 years old. Concerning the duration of coma that occurred soon after the accident, 64 remained comatose from 0 to 6 hours, 46 from 6 to 12 hours and 46 from 12 to 48 hours. 2. Subjective symptoms were observed in 96.8% of the patients. Among them, forgetfulness was noted in 89.7%, followed by irritability in 66.7%, headache in 59.6%, insomnia in 55.8%, limb pain in 46.8%, dull head feeling in 42.9% and dizziness in 36.5%. 3. Intellectual disturbances were observed in 68.6% of the patients, including impression disturbance in 58.3%, memory disturbance in 51.9%, calculation disturbance in 63.5%, thinking disturbance in 61.5% and disorientation in 14.1%. 4. Apathy and disorder of volition and interest which were found in 72.4% were included in personality change because all symptoms persisted for many years. Personality change was classified as follows: weakness of emotion and will (hypobulia) in 54.4%, infantilism in 35.2%, hyperactive, talkactive and lack of inhibition in 18.5%, lack of self-possession and unstable temper in 9.6%, depression in 15.3%, neurosis in 7.6% and schizophrenic state in 2.5%. Among these symptoms of personality change, weakness of emotion and will and infantilism were conspicuous among the patients who remained in a coma for more than 6 hours soon after the accident but showed no relationship with age. 5. Neurological symptoms that were found in 48.7% of the patients were classified as sensory disturbance in 25.6%, peripheral nerve symptoms in 16.0%, pyramidal symptoms in 14.1%, ataxia and cranial nerve symptoms in 7.1%, paroxysmal symptoms in 6.4% and focal symptoms in 4.5%, extrapyramidal symptoms in 21.8% (Parkinsonism in 4.5%, tremor in 10.9% and muscle rigidity in 16.0%) and vegetative symptoms in 37.2%. 6. At the time of investigation, 5 CO poisoning patients were classified as serious cases (3.2%), 20 as comparatively serious (12.8%) medium-degree cases, 28 as comparatively mild (17.9%) medium-degree cases, 37 as comparatively serious (23.7%) mild cases, 42 as comparatively mild (26.9%) mild cases, 24 (15.4%) as having symptoms which were not problematic, and 24 (15.4%) as having symptoms that markedly worsened due to complication. 7. A total of 138 (88.4%) cases had complications were classified as follows: 78 cases (50.0%) of hypertension, 62 cases (39.7%) of cerebral infarction, 24 cases (15.4%) of cardiac disturbance, 21 cases (13.5%) of diabetes mellitus, 14 cases (9.0%) of hepatic disturbance and six cases of silicosis (3.8%). 8. Cranial MRI was carried out for 129 cases (82.7%). Of the abnormal findings identified, cerebral atrophy accounted for 72.0% (93 cases), including moderate and severe cases in 47.2% (61 cases), pallidum lesion for 37.9% (49 cases), lacunar infarction (including cerebral infarction) for 52.7% (68 cases), and hippocampal atrophy for 18.6% (24 cases). Many cases of cerebral atrophy and hippocampal atrophy were observed in patients who remained in the initial coma for more than 12 hours and were 80 years of age or old. The cases of pallidum lesion were observed in patients who remained in the initial coma for more than 6 hours, and no relationship with age was found. The other findings, cerebral atrophy and lacunar infarction showed a slight relationship with age. 9. Among the moderate and serious cases of intellectual disturbance, cerebral atrophy constituted to 62.5%, lacunar infarction 68.7% and pallidum lesion 50.0%. Among the moderate and serious cases of personality change, cerebral atrophy constituted 78.5%, lacunar infarction 35.0% and pallidum lesion 50.0%. Moreover, among extrapyramidal symptoms, pallidum lesion constituted 58.6%, cerebral atrophy 55.1% and lacun
