We report a 56-year-old woman with progressive gait disturbance. Her mother had Parkinson's disease with onset at age 70. She died at age 74 and the post-mortem examination confirmed the diagnosis of Lewy body positive Parkinson's disease. The patient was well until the age of 50(1995) when she noted an onset of resting tremor and difficulty of gait. She also developed delusional ideation and was admitted to a psychiatric service of another hospital, where a major tranquilizer was given. The delusion disappeared but she developed marked rigidity. The major tranquilizer was discontinued and an anticholinergic and amantadine HCl were given. She showed marked improvement to Hoehn and Yahr stage II and was discharged. In 1995, when she was 52 years of the age, she developed delusion again and a major tranquilizer was given. She developed marked parkinsonism again and became Hoehn and Yahr stage V. The major tranquilizer was discontinued and she was treated with levodopa/carbidopa, trihexyphenidyl, bromocriptine, and dops. She improved remarkably to stage II. She was admitted to our service on October 8, 1996 for drug adjustment. She was alert and not demented. She was anxious but delusion or hallucination was noted. Higher cerebral functions were intact. Cranial nerve functions were also intact except for masked face and small voice. Her posture was stooped and steps were small. She showed retropulsion and moderate bradykinesia. Resting tremor was noted in her left hand. Rigidity was noted in both legs. No cerebellar ataxia or weakness was noted. Deep tendon reflexes were within normal range and sensation was intact. Her cranial MRI revealed some atrophic changes in the putamen, in which a T 2-high signal linear lesion was seen along the lateral border of the putamen bilaterally. In addition, posterior part of the putamen showed T 2-low signal intensity change. She was treated with 1.6 mg of talipexole, 6 mg of trihexyphenidyl, and 100 mg of L-dops. She was in stage III of Hoehn and Yahr. She developed neurogenic bladder with a large amount of residual urine for which she required catheterization. She was transferred to another hospital. Despite drug adjustment, she lost response to levodopa and her parkinsonism deteriorated gradually. She also developed syncope orthostatic hypotension. In April of 1998, she developed intracerebral hemorrhage and was admitted again on April 19, 1998. She was unable to stand and showed marked akinesia and rigidity. She was in stage V of Hoehn and Yahr. Her cranial CT scan revealed bilateral high-density lesions in the posterior parietal lobes. She developed dysphagia for which she required gastrostomy. She was transferred to another hospital but her clinical condition deteriorated further. On December 22, 1999, she developed fever and dyspnea and was admitted to our service again. She developed cardial arrest at the emergency room from hypoxia. She was resuscitated; however, she was comatose with loss of brain stem reflexes. Later on she developed generalized myoclonus. She developed cardiac arrest and pronounced dead on December 28, 1999. The patient was discussed in a neurological CPC. The chief discussant arrived at the conclusion that the patient had striatonigral degeneration because of poor response to levodopa in the later course, autonomic failures, and MRI changes. Some other participants thought that the patient had a form of familial Parkinson's disease. Opinions were divided into these two possibilities. Post-mortem examination revealed that the substantia nigra showed intense neuronal loss and gliosis, however, no Lewy bodies were seen. In addition, intracytoplasmic inclusions were seen in oligodendrocytes. The putamen was markedly atrophic in its posterior part with marked gliosis and neuronal loss. The ventromedial part of the pontine nucleus also showed neuronal loss and intracytoplasmic glial inclusions. Pathologic diagnosis was multiple system atrophy. In the parietal lobe, an arteriovenous malformation with bleeding was noted. This is very unique case. Although her mother had Lewy body-positive Parkinson's disease, the patient had Lewy body-negative multiple system atrophy with a-synuclein-positive glial inclusions. Whether this is just a coincidental occurrence or the presence of a genetic load for Parkinson's disease might triggered her multiple system atrophy is an interesting question to be answered in future.

We reported a 74-year-old male case of progressive supranuclear palsy (PSP) who responded to tandospirone citrate, a serotonin receptor (5-HT1A) agonist. The patient manifested postural instability and gait disturbance at 71 years. Additionally, he showed vertical gaze paresis, regidity of the neck, extremities and trunk, bradykinesia and mild cognitive impairment. A brain MRI revealed moderate atrophy of bilateral frontal/temporal lobes and of midbrain tegmentum one year after the onset. The patient had been diagnosed as PSP and treated with L-DOPA. However, L-DOPA therapy showed only transient response for a few months. His symptoms deteriorated gradually, and he became unable to sit, stand up or walk by himself. Tandospirone citrate was additionally administered at 30 mg/day. Rigidity and bradykinesia were remarkably improved in two weeks after the start of tandospirone treatment. He became able to stand up and walk a short distance with supports in four weeks. Cognitive disturbance was also slightly improved. Tandospirone citrate was effective on our case of PSP, especially on rigidity. Our findings suggest that combination of levodopa and tandospirone citrate is a useful therapy for PSP.

Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder caused by high instability and extension of CAG sequences within the coding region of IT15 gene. It affects both sexes and age at onset of the disease may be different but usually occurs in midlife. The term Juvenile Huntington's disease is generally applied to 10% of the cases with onset before 20. We present clinical features and results of DNA analysis in 16 patients from 14 families aged 9 to 36. The age of onset was between 5 to 20 years; duration of the disease was from 2 to 16 years. In 10 cases the mutated gene was transmitted by the affected father; only in two cases by the mother. In all cases anticipation manifested by earlier onset of the disease in subsequent generations and expansion of CAG repeats was documented. The number of CAG repeats was between 50 and 92 (mean 67.3). Progressive mental deterioration, declining school performance, hyperactivity and emotional disturbances were the first symptoms of juvenile HD. Neuropsychological assessment showed mean IQ in Wechsler test 59.6 and Mini-Mental State Examination scores 22.8. Rigidity and bradykinesia were predominant features in the cases with juvenile onset, the remaining ones developed choreatic movements. Three persons had epileptic seizures; two (both females) revealed behaviour and psychiatric disturbances. Amplitudes of somatosensory evoked potentials, visual evoked potentials and brainstem auditory evoked potentials were markedly reduced. MRI of the brain showed atrophy of heads of the caudate nuclei, putamen and globus pallidus.

Progressive encephalomyelitis with rigidity and myoclonus (PEWR) is a rare neurological disorder, characterised by muscular rigidity, painful spasms, myoclonus, and evidence of brain stem and spinal cord involvement. A 73-year-old white man was admitted with a 10-day history of painful muscle spasms and continuous muscle rigidity on his left lower limb. He had involuntary spasms on his legs and developed encephalopathy with cranial nerves signs and long tract spinal cord symptomatology. Brain CT scan and spinal MRI were normal. The CSF showed lymphocytic pleocytosis and no other abnormalities. EMG showed involuntary muscle activity with 2-6 seconds of duration, interval of 30-50 ms and a frequency of 2/second in the left lower limb. Anti-GAD antibodies were detected in the blood. We detected radiological signs of lung cancer during the follow-up, which proved to be an oat cell carcinoma. The patient died two weeks after the diagnosis of the cancer.

A 69-year-old woman was admitted to our hospital due to an interval form of carbon monoxide (CO) poisoning one month after acute CO poisoning. On admission, she had disorientation, memory disturbance, apathy, masked face, muscle rigidity, bradykinesia and parkisonian gait. An MRI (FLAIR image) revealed high signal intensity lesions in the bilateral globus pallidus and the white matter of the frontal lobe. Hyperbaric oxygen (HBO) therapy at 2 atmospheres for 60 min was given every day, in addition to citicoline, levodopa/DCI and selegiline hydrochloride. Cognitive disturbance and parkinsonism gradually decreased, and abnormal signals in the bilateral globus pallidus and the cerebral white matter were attenuated after the treatment. Neuropsychiatric abnormalities except for a slight gait disturbance disappeared one and a half month after starting the treatment. In addition to HBO therapy, administration of citicoline, lovodopa and selegiline may be useful in the case of the interval form of CO poisoning.

A 48-year-old woman noticed her right breast swelling since a few weeks earlier. Rigidity in the AC area, hotness, swelling and peau d'orange appearance of the right whole breast were recognized. She was diagnosed as inflammatory breast cancer clinically and invasive ductal carcinoma with lymphatic invasion pathologically. The patient underwent primary systemic therapy with 4 cycles of CEF (cyclophosphamide 500 mg/m(2), epirubicin 100 mg/m(2), 5-fluorouracil 500 mg/m(2)) followed by 4 cycles of docetaxel (70 mg/m(2)). The effect of chemotherapy showed a partial response evaluated by mammography and ultrasonography, and complete response by MRI before surgery. Right mastectomy with level II lymph node dissection was performed. Pathologically, complete response was confirmed (pCR). Although IBC has been known for its poor outcome, this case suggests IBC will show a better prognosis by chemotherapy such as CEF followed by docetaxel.

We report a 53-year-old woman with probable Bassen-Kornzweig syndrome. Her parents were a consanguineous marriage. At two years of age, she developed night blindness. During her childhood she had severe diarrhea that disappeared in adulthood. At 26 years of age, she was diagnosed as having retinitis pigmentosa and her visual acuity became worse thereafter. She noted tremor in the right hand at 37 years of age, gait ataxia at 42, and developed tremor in the bilateral lower extremities at 48. On admission, bilateral visual disturbance, resting and postural tremor, moderately poor coordination, mild distal dominant sensory impairment, an absence of tendon reflex in all four extremities, moderate to severe gait ataxia, and positive Romberg sign were found. Muscle rigidity and akinesia were not observed. Intelligence and muscle power were normal and pathological reflexes were absent. Acanthocytes were found in blood. Serum chemistry showed remarkable decreases in total cholesterol (54 mg/dl, normal 180-220), triglyceride (0 mg/dl, normal 30-150), beta-lipoprotein (3 mg/dl, normal 190-500), apoA-1 protein (66 mg/dl, normal 105-184), apoA-2 protein (11 mg/dl, normal 26-46), apoB protein (0 mg/dl, normal 38-104), apoC-2 protein (1.1 mg/dl, normal 1.2-6.4), vitamin A (297 ng/ml, normal 431-1,041), and vitamin E (0.19 ng/dl, normal 0.75-1.41). While, a marked increase in PIVKA II (703 mAU/ml, normal<40) due to a decrease in vitamin K was found. She was thus diagnosed as having Bassen-Kornzweig syndrome or hypo-betalipoproteinemia. Although brain MRI was normal, single-photon emission CT (SPECT) showed mildly decreased perfusion in the left parietal cortex and right striatum. Motor nerve conduction velocities were normal, but sensory nerve action potentials were not evoked in all four extremities. Surface EMG recorded on the right radial extensor and flexor carpi muscles at rest showed a 4.5 Hz tremor. Vitamin replacement therapy with vitamin A (10,000 IU/day), E (200 mg/day), and K (10 mg/day) was initiated. Several days after treatment, amplitude of resting tremor ameliorated mildly. Clonazepam was administered (0.5 mg/day) for further treatment. After one-month of treatment, vitamin A (656 ng/ml) and E (0.39 mg/dl) levels were elevated and PIVKA II level (29 mAU/ml) decreased. Only a mild right hand tremor remained, but sensory impairment and gait ataxia were not changed. The cause of Bassen-Kornzweig syndrome is a deletion of the microsomal triglyceride transfer protein (MTP) gene. While, familial hypo-betalipoproteinemia, due to a mutation of apolipoprotein B gene, is known to show the same phenotype. Because of the patient's refusal of genetic examination, which disease she has cannot be conclusively determined. Intention tremor was reported in Bassen-Kornzweig syndrome. However, her 4.5 Hz tremor was also present at rest, which resembled resting tremor in Parkinson's disease. Pathophysiology of Bassen-Kornzweig syndrome is known to be due to hypo-vitaminosis. Decreased [18F]-dopa uptake in striatum of patients with long-term hypo-vitamin E has been reported in PET study. Mild hypoperfusion was found in the striatum of the present cases: indicating that her tremor was associated with striatonigral damage. Thus, careful observation of extrapyramidal signs is necessary in abeta- or hypo-betalipoproteinemia.

We report the case of a 29 year old woman with a complex movement disorder syndrome due to the combination of coexisting pathological triplet repeat expansions of huntingtin and ATXN8 genes. The disease course was characterized by mental disturbances including cognitive decline and changes in personality starting at the age of 12 years, followed by twisting motions, intentional tremor and gait ataxia. Later Parkinsonian symptoms of micrographia, bradykinesia, muscle rigidity and mental decline became dominant. Brain MRI showed hypoplasia of the nucleus caudatus and generalized atrophy; MR spectroscopy revealed a decrease of all typical metabolites except for an increased level of lactate and acetate. Therapeutic trials with pramipexole, ropinirole and tetrabenazine showed no benefit, while levetiracetam caused agitation and hallucinations. We discuss phenotype-genotype correlation and the rule of triplet repeat expansions of gene ATXN8.

We describe a 78-year-old Japanese woman with early-stage progressive supranuclear palsy (PSP). She had a 3-week history of postural instability and gait disturbance. On examination, upper vertical gaze palsy, akinesia, hyperreflexia with pathological reflexes, hesitation, and postural instability were observed. Rigidity and resting tremors were not apparent. Brain MRI revealed atrophy of the frontotemporal lobes and dilatation of the third ventricle. A month later, she died of cerebral infarction. The total duration of her clinical course was approximately 2 months. The brain weighed 1180 g after fixation. Macroscopically, mild atrophy of the frontal lobes and mild depigmentation of the substantia nigra were observed. The conspicuous findings included degeneration confined to the subthalamic nucleus and substantia nigra and widespread but infrequent tau-positive neurofibrillary tangles/pretangles and glial fibrillary tangles (tuft-shaped astrocytes, coiled bodies and argyrophilic threads) in the brain. It has been reported that the most affected areas in PSP are the globus pallidus, subthalamic nucleus and substantia nigra. We suggest that degeneration in PSP would start with involvement of the substantia nigra and subthalamic nucleus.

Corticobasal degeneration (CBD) is an uncommon, sporadic, neurodegenerative disorder of mid- to late-adult life. We describe a further example of the pathologic heterogeneity of this condition. A 71-year-old woman initially presented dysarthria, clumsiness, progressive asymmetric bradykinesia, and rigidity in left arm. Rigidity gradually involved ipsilateral leg; postural instability with falls, blepharospasm, and dysphagia subsequently developed. She has been previously diagnosed as unresponsive Parkinson's Disease. At our clinical examination, she presented left upper-arm-fixed-dystonia, spasticity in left lower limb and pyramidal signs (Babinski and Hoffmann). Brain MRI showed asymmetric cortical atrophy in the right frontotemporal cortex. Neuropsychological examination showed an impairment in visuospatial functioning, frontal-executive dysfunction, and hemineglect. This case demonstrates that association of asymmetrical focal cortical and subcortical features remains the clinical hallmark of this condition. There are no absolute markers for the clinical diagnosis that is complicated by the variability of presentation involving also cognitive symptoms that are reviewed in the paper. Despite the difficulty of diagnosing CBD, somatosensory evoked potentials, motor evoked potentials, long latency reflexes, and correlations between results on electroencephalography (EEG) and electromyography (EMG) provide further support for a CBD diagnosis. These techniques are also used to identify neurophysiological correlates of the neurological signs of the disease.
