[A case of chronic inflammatory demyelinating neuropathy associated with antibodies to gangliosides GM1 and GalNAc-GD1a].

In January 1993, a 43-year-old man was admitted to our hospital for left wrist-drop. Neurological examinations revealed asymmetrical distal weakness in the upper limbs. Deep tendon reflexes were normal in all 4 limbs. Sensory and autonomic nervous functions were intact. CSF examinations were within normal limits. Thin-layer chromatography with immunostaining revealed serum antibodies that reacted with GM1 and GalNAc-GD1a. Motor nerve conduction studies revealed abnormal temporal dispersion, and a low amplitude of compound muscle action potential in the left radial nerve. Neurological symptoms gradually improved with prednisolone over one and a half years. He was hospitalized again in January 1995, because of right wrist-drop and slight sensory loss of the limbs. Those findings were improved by methylprednisolone (1,000 mg/day) for 3 days. The interval until maximal disability in this patient was more than one month for each admission. This case must belong to inflammatory demyelinating neuropathy.

[The diagnosis of amyotrophic lateral sclerosis supported by motor evoked potential and brain MRI studies].

A 57-year-old man developed severe muscle weakness and atrophy of the upper extremities within a five-month period. Neurological examination revealed severe weakness and atrophy in the scapular muscles and proximal and distal muscles of the upper extremities. Fasciculations were also observed in the various muscles of the upper extremities. There was neither muscle weakness, atrophy nor fasciculation in either his face, neck muscles or lower extremities. He had no pseudobulbar or bulbar signs. Tendon reflexes were mildly hyperactive in the jaw and lower extremities, and normal in the upper extremities. There were no pathological reflexes, spasticity or sensory disturbances. The needle EMG study revealed denervation potentials in all muscles of the upper extremities examined. The nerve conduction study revealed no findings of the conduction block. Cervical spine X-rays revealed the narrowing of the spinal foramens at the left C3/C4 and bilateral C4/C5, C5/C6, and C6/C7 intervertebral levels. In addition, magnetic resonance imaging (MRI) revealed compressions of the cervical cord at C4/C5 and C5/C6 intervertebral levels. These clinical and neuroradiological findings resembled those of the cervical spondylotic amyotrophy (CSA). However, the motor evoked potential (MEP) study revealed the pyramidal tract dysfunction above the levels of the pyramidal decussation. Furthermore, brain MRI revealed abnormal foci in both internal capsules which were characterized by hyperintense relative to cortical gray matter on T2-weighted images and still hyperintense to white matter on proton-density-weighted images. In addition, T2-weighted images demonstrated a low signal within the motor cortex and hyperintense lesions in the white matter of the precentral gyri. These MRI findings indicated the degeneration of the pyramidal tract and corresponded to those found in the patients with amyotrophic lateral sclerosis (ALS) which have been recently reported. It has been difficult to distinguish ALS from CSA. However, MEP and brain MRI studies were useful for distinguishing these two diseases in this patient. In addition, this patient showed typical MRI findings suggesting the degeneration of the pyramidal tract, although this patient had a relatively short course of illness and did not show obvious physical findings suggesting pyramidal tract dysfunction.

[(Neurological CPC.55). A 60-year-old woman with progressive cerebellar ataxia, myoclonus, and dementia].

We report a 60-year-old woman with progressive ataxia, myoclonus, choreoathetosis, and dementia. She was well until 27 years of the age when she noted an onset of gait disturbance and speech disturbance. She noted abnormal involuntary movements in her four limbs at 42 years of the age. Her symptoms had progressively become worse and she fell down frequently by her 52 years of the age. In addition, her family members noted gradual decline in her intelligence. She was admitted to our hospital in February of 1993 when she was 57-year-old. On admission, she showed dementia, scanning speech, ataxic gait, limb ataxia, action myoclonus, and choreic movements which involved her four limbs. Deep tendon reflexes were slightly exaggerated in the lower limbs; no Babinski sign was noted. Sensation was intact. Laboratory findings were unremarkable. Cerebral MRI revealed atrophy of the cerebellar cortex, superior cerebellar peduncle, brain stem, and the cerebral cortex; the third ventricle and the lateral ventricles were dilated; furthermore, T2-high signal lesions were seen in the cerebral white matter and in the pontine base. Her clinical course was one of the progressive deterioration of her ataxia, involuntary movements, and dementia. She expired on April 24, 1996 when she was 60-year-old. She was discussed in a neurologic CPC and the chief discussant arrived at the conclusion that the patient had dentatorubral-pallidoluysian atrophy. A minor opinion was that she might have had myoclonus epilepsy with ragged-red fibers. Postmortem examination revealed atrophy, gliosis, and neuronal loss in the external segment of the globus pallidus, subthalamic nucleus, red nucleus, and in the dentate nucleus. In addition, the gracil and cuneiform nuclei showed neuronal loss and spheroid formation; the spinocerebellar tracts were retained. The substantia nigra and the locus coeruleus were intact. No ragged-red fibers were seen in the muscle biopsy specimen taken in February, 1993. The neuropathologic findings were consistent with the diagnosis of dentatorubral-pallidoluysian atrophy.

[Chronic inflammatory demyelinating polyneuropathy. Report of six cases].

Chronic inflammatory demyelinating polyneuropathy is a heterogeneous disease characterized by symmetrical motor and sensitive alterations, absence of tendon reflexes and increased cerebrospinal fluid protein levels. We report 6 patients with the disease, (three males) aged 41 to 70 years old. Four had the classical presentation and two had an asymmetrical paresis, that predominated in superior limbs. These patients had a proximal block with scarce prolongation of distal nerve conduction velocity. In all patients, underlying illnesses were discarded with a full diagnostic work up. Subjects were followed from 2 to 14 months after the diagnosis. In all, treatment with steroids improved muscle strength and sensitivity.

[Neurological CPC.57. An 80-year-old woman with four years history of muscle atrophy involving lower extremities predominantly on the right side].

We report an 80-year-old woman with progressive muscular atrophy predominantly involving her right lower extremity. She was well until 1992 (75 years of age) when she noted an onset of weakness in her right leg which had got progressively worse. She was admitted to our service in July 1994. On admission, general physical examination was unremarkable. She was alert and well oriented without dementia. Higher cerebral functions were normal. Cranial nerves also appeared intact. She dragged her right leg in walking. Mild to moderate weakness (2/5 to 4/5) was noted in muscles in her right lower extremity more in the distal part. Deep tendon reflexes were within normal limits, and the plantar response was flexor bilaterally. Sensation was intact. Laboratory examinations were also unremarkable except for slight increase in CK which was 470 IU/l. CSF was also normal. EMG revealed neurogenic changes in the lower extremities. She was admitted to Aoki Hospital on October 21, 1994, by that time, her weakness in the right lower extremity had gotten worse in that the muscle strength of the right extensor hallucis longus was 0 and tibialis anterior 2; muscle atrophy was also prominent in her right leg; the right ankle jerk could not be elicited. In the subsequent course, weakness and atrophy appeared in her left lower extremity, however, upper extremities and cranial nerves had never been affected. Babinski sign was always negative. In February 1996, she developed delusional ideation of self persecution, and showed difficulty in communication with medical staffs. She developed fever of 38.7 degrees C on June 13, 1996 expired on the next day. The patient was discussed in a neurological CPC, and the chief discussant arrived at the conclusion that the patient had a form of spinal muscular atrophy. Opinions were divided between ALS and spinal muscular atrophy. Post-mortem examination revealed marked loss of anterior horn neurons in the lumbar area with astrogliosis. Bunina bodies were seen in some of the remaining neurons. No myelin pallor was noted in the pyramidal tracts, however, atrophy and loss of Betz cells were noted in the motor cortex. Other cortical areas were unremarkable. The neuropathologist arrived at the conclusion that the patient had ALS. This patient was unique in that she had asymmetric atrophy and weakness limited to the lower extremities. This is quite unusual as ALS of four years duration. In addition, the patient developed some mental change which was thought to represent dementia by some participants. But no clear morphologic changes were seen to account for her mental change.

Diabetic polyneuropathy in the elderly. Prevalence and risk factors in two geographic areas of Italy. Italian General Practitioner Study Group (IGPSG).

OBJECTIVE: To assess the prevalence and the risk factors of diabetic polyneuropathy in representative samples of elderly individuals. PATIENTS: 4191 subjects 55 years and older from two areas of Italy were screened by their general practitioners (GPs) and those positive for neuropathic symptoms were subjected to a standard clinical examinations. METHODS: The screening questionnaire included a list of clinical conditions possibly causing polyneuropathy, including diabetes. In patients with diabetes, the date of diagnosis, the most recent fasting and post-prandial blood glucose value and glycosylated hemoglobin were sought. Probable polyneuropathy was diagnosed through impairment of 2 or 3 nerve functions (strength, sensation, tendon reflexes) in the extremities with symmetrical and distal distribution. RESULTS: The sample included 347 patients with diabetes (8.3%). Sixty-six of them (19%) had symptoms and signs consistent with probable polyneuropathy (overall prevalence 1.6%). The disease prevailed in women and in subjects aged 75 years and older. Diabetic patients with polyneuropathy had a longer disease course (P < 0.02) and high mean fasting (P < 0.001) and post-prandial (P < 0.02) blood glucose. CONCLUSION: Diabetic polyneuropathy in the elderly is a fairly common clinical condition prevailing in women and in subjects 75 years and older. Risk factors for polyneuropathy include prolonged disease duration and high mean fasting and post-prandial blood glucose.

Intramedullary cysticercosis.

An unusual case of intremedullary cysticerosis in a 22-year-old Mexican female is presented. The patient had a marked paraparesis with a D12 sensory level, absent deep tendon reflexes and no sphincteric disturbances. Pain in the spine was a prominent feature. A complete myelographic block opposite D12 proved at laminectomy to be due to a solitary cysticercus vesicle. It was removed from the conus medullaris through a right ventro-lateral myelotomy. The patient recovered.

[A case of axonal form of Guillain-Barré syndrome associated with anti-GM1b IgG antibody following Penner 4 Campylobacter jejuni infection].

A 41-year-old woman was admitted to the hospital because of diarrhea followed by progressive weakness of all extremities and dysphagia. On neurological examination, she showed facial diplegia, bulbar palsy, flaccid quadriplegia, and absence of all deep tendon reflexes in addition to Laségue's sign. The Campylobacter jejuni Penner type 4 was isolated from the culture of stool. The test of anti-GM1b antibody (IgG) was positive in the serum. The protein content was elevated in the cerebrospinal fluid without pleocytosis. The studies of motor nerve conduction velocity showed a pattern of the axonal neuropathy. This is a case of Guillain-Barré syndrome presenting with the axonal neuropathy possibly due to the immune response directed to GM1b which is triggered by the Campylobacter jejuni Penner type 4 infection.

[A case of progressive supranuclear palsy associated with bilateral vocal cord abductor paralysis].

We report a 65-year-old male with progressive supranuclear palsy (PSP) who developed bilateral vocal cord abductor paralysis (VCAP). The patient was admitted to our hospital because of impaired gait. He was well until two years earlier, when he began to walk unsteadily. During the next two years, dysarthria and dysphagia developed and his gait worsened gradually. On admission, neurological examination showed impaired vertical and incomplete lateral gaze. His speech was slow and monotonous. Contractures were found in the neck muscles and elbows. The deep tendon reflexes were increased in the upper and decreased in the lower extremities. Babinski sign was negative. Snout and forced grasping reflexes were elicited. He showed marked bradykinesia. Magnetic resonance imaging revealed a midbrain tectum atrophy. Single photon emission tomography showed severe hypoper-fusion in the frontal cortex. No improvement was provided by the administration of levodopa-carbidopa, bromocriptine, droxydopa and amitriptyline. One month after admission, inspiratory stridor developed at night. The laryngofiberscopic examination demonstrated VCAP. An emergency tracheostomy relieved his respiratory distress. Although VCAP rarely occurs in neurodegenerative disorders other than multiple system atrophy, attention to VCAP should be required in PSP patients.

[A case of superficial siderosis of the central nervous system with bilateral vestibular dysfunction].

A 58-year-old woman developed slowly progressive hearing loss, anosmia, and unsteady gait. She had neither repeated episode of headache nor a past history of neurosurgical operation or head injury. Neurological examination revealed anosmia, moderate degree of sensorineural hearing loss. She showed loss of caloric response bilaterally. No nystagmus was found. Romberg sign was present. No cerebellar ataxia was noted in the finger-to-nose or the heel-to-knee test. No adiadochokinesis was noted. Deep tendon reflexes were increased in both upper and lower extremities. Sensation was intact. She showed disturbance of the righting reflex in the tilt-table examination. CSF were under normal pressure, xanthochromic with siderophages. CSF total protein and ferritin level were elevated. T2-weighted image (TE4000/TR100) of high field strength magnetic resonance imaging (MRI) showed marginal hypointensity of the brain stem, the Sylvian fissures, the tips of temporal lobes, anterior cerebellar surfaces and the entire spinal cord. Angiography of the cerebral vessels and spinal arteries failed to identify the source of bleeding. It seemed likely that she had lost bilateral vestibular and auditory functions caused by hemosidelin deposition to her eighth nerves which are often affected by this disorder. Her disturbance of gait and station was apparently similar to cerebellar ataxic gait, however, she did not have limb ataxia. The electronystagmogram revealed marked degree of vestibular dysfunction (VOR) and relative sparing of cerebellar function (OKN). Her disturbance of the righting reflex in the tilt-table examination and the characteristic feature of her Romberg sign with directional preponderance also indicate that the bilateral loss of vestibular functions, i.e., vestibular ataxia caused her dysequilibrium syndrome. It is our impression that vestibular ataxia might precede cerebellar ataxia commonly reported so far.

[A 85-year-old woman with one year history of convulsion, dementia, and consciousness disturbance].

We report a 85-year-old woman who died after one year history of convulsion, dementia, and consciousness disturbance. She was apparently well until January 6, 1995 when she was 85 year old; on that evening, she suddenly stated that some one was in her room and she became confused. A local MD gave her diazepam and she fell into sleep. At 3 o'clock in the following morning, she developed tonic-clonic convulsion in her right lower extremity which showed a march to her right upper extremity and the left lower extremity. She was admitted to our hospital. On admission, she was comatose with respiratory acidosis. She was intubated and placed on a ventilator. She was treated with intravenous phenytoin. She gradually gained consciousness and became alert. Respiration became normal. Her MRI revealed ventricular dilatation, fronto-parietal cortical atrophy, and a T1-low and T2-high signal intensity lesion in the left occipital lobe. She was discharged for out patient follow-up on February 4, 1995. Since then, she noted loss of memory and small step gait. A follow-up CT scan revealed a mass lesion which showed a ring-shaped enhancement in the left occipital lobe and was admitted again. On admission, she was alert but markedly demented. The optic fundi was unremarkable, but she appeared to have right homonymous hemianopsia. No motor weakness was noted. In Gd-DTPA enhanced MRI, the above tumor showed a ring enhancement. The diagnosis of glioblastoma was entertained, however, considering her age, she was treated with intravenous glycerol and intramuscular steroid. She was discharged for out-patient follow-up on July 15, 1995. Her gait disturbance had progressively become worse and she developed nausea and vomiting and was admitted again on October 2, 1995. On admission, she was somnolent and markedly demented. Brain stem responses were retained normally. She was unable to stand or walk. Deep tendon reflexes were slightly increased in the right upper extremity and the plantar response was extensor on the right. Her hospital course was complicated by respiratory tract infection and respiratory acidosis. She expired on November 2, 1995. The patient was discussed in a neurological CPC and the chief discussant arrived at the conclusion that she had a glioblastoma involving the left occipital lobe and the adjacent areas. Post-mortem examination revealed an infiltrating tumor in the left occipital lobe. On microscopic examination, the tumor was very cellular; nuclear atypism was marked and tumor cells undergoing mitosis were seen. In some areas, capillary proliferation was seen. Histologic characteristics were consistent with glioblastoma.

[A case of idiopathic orthostatic hypotension with selective involvement of postganglionic noradrenergic neurons].

A 44-year-old man had a 30-year history of orthostatic hypotension and diarrhea. One month before admission, he suddenly lost consciousness by defecation, and was hospitalized. He became alert within two days, but he could not sit up due to severe orthostatic hypotension. At that point, he was transferred to our hospital. On admission, talipes and microdactylia were noted. Neurological examination revealed brisk patellar tendon reflexes. Anhidrosis or impotence was not present. Analyses of blood and urine yielded normal results. Cardiological examination revealed no abnormality that could be responsible for the hypotension. MR images of the brain were also normal. However, single photon emission tomography revealed diffuse hypoperfusion of the brain. A head-up tilt (50 degrees) test induced a remarkable fall in systolic blood pressure from 149 (heart rate; 65/min) to 64 mmHg (83). Immersion of hand in ice-cold water failed to increase blood pressure. Heart rate variation and cystometry results, which represent the function of parasympathetic nerves, were normal. Warming of his body caused normal sweating. Intravenous injection of low doses of norepinephrine and methoxamine increased blood pressure while isoproterenol remarkably increased heart rate, suggesting that both alpha- and beta-receptors developed supersensitivity. Instillation of 5% cocaine and 5% tyramine into the conjunctival sac failed to cause pupillary dilation. Clinical findings and pharmacological challenge test results suggested that the main lesion of his autonomic nervous system was selectively confined to the postganglionic sympathetic nerves and noradrenergic (not cholinergic) neurons. The autonomic failure of our patient can be classified as idiopathic orthostatic hypotension. However, most patients with idiopathic orthostatic hypotension or pure autonomic failure complain of anhidrosis and impotence, which were not noted in our patient. These symptomatic differences may be the result of the highly selective involvement of noradrenergic neurons in the postganglionic sympathetic system in our patient.

[A case of malignant rheumatoid arthritis with transverse myelopathy and multiple lacunar infarction].

We reported a 34-year-old woman with malignant rheumatoid arthritis (MRA) associated with transverse myelopathy and multiple lacunar infarction. She had suffered from MRA for 9 years, then developed sensory disturbance of left big toe and weakness of right lower limb. Neurological examination revealed the muscle weakness of right lower limb. Deep tendon reflexes were hyperactive in bilateral lower limbs. Babinski's sign was positive bilaterally. Superficial sensation was decreased below Th10 level on the left side. Urinary bladder and rectal disturbance were not present. Laboratory examination disclosed perinuclear antineutrophil cytoplasmic autoantibody (p-ANCA) and anti-nuclear antibody (ANA). Multiple lacunar infarction and syringomyelia were found by MRI studies. Histological examinations of skin ulcer biopsied at 17 years of age disclosed vasculitis. We speculated that vasculitis associated with MRA might cause the damage of central nervous system (CNS) in our case. The p-ANCA may accelerate the vasculitic changes in CNS.

[A case of post-hemiplegic painful dystonia following thalamic infarction with good response to botulinus toxin].

We report a 67-year-old hypertensive right-handed woman who developed severe pain and dystonia in her left upper and lower extremity after a thalamic infarction. She was well until 9 months prior to the present admission to our hospital, when she had an acute onset of left hemiparesis which turned out to have been caused by a thalamic infarct. Her hemiparesis showed nearly complete recovery during the next four months. She noted an onset of severe spontaneous pain and difficulty in using her left hand four months prior to the present admission. Neurologic examination on admission revealed an alert and well oriented Japanese woman. Cranial nerves were intact. Although she did not have weakness, her left hand showed thalamic posture, and upon standing, she showed a dystonic posture in which her left forearm took pronation and flexion at the elbow joint and her left lower extremity took extension in the knee joint and planter flexion in the ankle joint. Her dystonic posture increased during walking and disappeared in the supine position. She complained of severe spontaneous pain and tingling sensation in her left extremities. Position sense was diminished in her left leg. However other sensations were intact. She had slight ataxia on the left side. Deep tendon reflexes were symmetric, but the planter response was extensor on the left side. MRI revealed a small lacunar infarct involving the right posterolateral thalamic region. EMG with surface electrodes revealed non-reciprocal tonic discharges in the left biceps brachii and forearm flexor and extensor muscles. She responded poorly to various medications. Only trihexyphenidyl showed partial alleviation of her pain and dystonic posture. We thought her pain might be caused by dystonic contraction of the skeletal muscles, at least in part. We injected 25 IU of botulinus toxin as a total dose into her biceps brachii, triceps brachii, and wrist flexor muscles. A few days after the injection, her dystonic posture began to show marked improvement; as her dystonia improved, her pain also showed marked improvement. This patient appeared to represent a case of post-hemiplegic dystonia. Her pain was initially thought to be the thalamic pain. However, as her pain disappeared with improvement of her dystonia, her pain is most likely to have been caused by the dystonic muscle contraction. Botulinus toxin treatment appears to be useful for post-hemiplegic painful dystonia.

[Mitochondrial neurogastrointestinal encephalomyopathy presenting with protein-losing gastroenteropathy and serum copper deficiency: a case report].

We report a 56-year old female with mitochondrial neurogastrointestinal encephalomyopathy (MNGIE), presenting with protein-losing gastroenteropathy and serum copper deficiency. There was no neuromuscular disease in her family members. Three years prior to admission, she developed severe gastrointestinal symptoms including diarrhea, nausea, vomiting and ascites, and was diagnosed as having protein-losing gastroenteropathy based on alpha(1)-antitrypsin clearance and other tests. She was referred to our department when neurological symptoms were apparent. Neurological examinations revealed bilateral ptosis, ophthalmoplegia, hearing loss, facial and limb muscle weakness, mild sensory deficit of vibration on her feet and hypoactive deep tendon reflexes. Pigmentary retinopathy, cerebellar ataxia and heart block were not seen. Serum copper level was decreased to 45 micrograms/dl (normal: 83-155). Chronic intestinal pseudo-obstruction was proven by X-ray studies, and diffuse leukoencephalopathy demonstrated on brain MRI. On EMG, motor nerve conduction velocities were prolonged with temporal dispersion. Her muscle biopsy from biceps brachii muscle showed both neuropathic and myopathic changes, scattered ragged-red fibers and focal cytochrome c oxidase deficiency. Southern blot and polymerase chain reaction analysis on mitochondrial DNA showed no deletions nor point mutations. The clinical and pathologic findings of the present patient fulfilled the diagnostic criteria of mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) proposed by Hirano et al. There are few reported patients with MNGIE in Japan, but none presented with protein-losing gastroenteropathy and serum copper deficiency. Since the copper is a cofactor of cytochrome c oxidase, decreased serum copper level may aggravate the respiratory chain enzyme metabolism in mitochondria. Therefore, treatment for gastrointestinal tract disturbance and copper administration may be necessary to prevent disease progression.

[Inflammatory sensory ataxic neuropathy presenting with alternating skew deviation on lateral gaze: a case report].

We report a 56-year-old female with chronic progressive sensory ataxic neuropathy presenting with alternating skew deviation on lateral gaze in the clinical course. She initially developed dysesthesias in the hands and feet asymmetrically, then gait disturbance developed over several months, and she was admitted to our hospital. Neurological examinations revealed profound deep sensory loss and mild superficial sensory disturbance with the absence of deep tendon reflexes, but muscular strength was completely preserved. EMG showed no evoked response of sensory nerve velocities and normal motor nerves. Sural nerve biopsy showed moderate demyelination with mild infiltration of inflammatory cells, and no vasculitis or onion bulb formation. CSF examination revealed elevation of cell counts and protein with marked intrathecal IgG synthesis and myelin basic protein, but finding of neurosyphillis. Serological examinations did not show any evidence of collagen disease, paraproteinemia, retrovirus infections or Lyme disease. Serum antiganglioside antibodies and anti-Hu antibody were negative. No evidence of malignancy was seen by radiological examinations and assays of tumor markers. In the weeks after admission, gait ataxia progressively worsened, and then she developed alternating skew deviation on lateral gaze, suggesting that the CNS was involved. No responsible lesion was detected on MRI. Corticosteroid administration improved not only the CSF findings, but also the neurologic symptoms, including the alternating skew deviation on lateral gaze. Although the disease entity was not identified, inflammatory demyelinating processes and immune-mediated mechanisms were considered to play important roles.

Scheuermann's kyphoscoliosis associated with Charcot-Marie-Tooth syndrome.

Much confusion and disagreement exists regarding the classification and characteristics of inherited disorders manifesting neurogenic muscular atrophy. Many authors consider Charcot-Marie-Tooth syndrome (CMTS) and Roussy Levy syndrome (RLS) forme fruste or variants of Friedreich's ataxia (FA). Familial kyphoscoliosis has often been described in FA and RLS but not with CMTS. The purpose of this paper is to present detailed clinical and laboratory findings in a family with three cases of Scheuermann's kyphoscoliosis and CMTS in three generations. In all cases Scheuermann's kyphoscoliosis was associated with pes cavus, markedly diminished vibratory and position sensation in the lower extremities, absent deep tendon reflexes and muscular atrophy, predominantly of the distal muscles. Fine rhythmic tremor of outstretched hands and positive Romberg sign were present in one case only. Serum creating phosphokinase was elevated in two cases. Motor nerve conduction studies revealed impaired function in the median, ulnar, tibial and peroneal nerves. Sensory nerve conduction wal also impaired in median and ulnar nerves. There was evidence of left ventricular hypertrophy in one case only. The nosology and relationship between CMTS, RLS and FA are discussed.

[A case of acute inflammatory demyelinating neuropathy associated with autoimmune-type chronic active hepatitis].

We presented a case of acute inflammatory demyelinating polyneuropathy associated with autoimmune chronic active hepatitis (AI-CAH). This is the third case report of neuropathy in AI-CAH. A 64-year-old male with chronic liver dysfunction was admitted to the hospital because of high fever, distal weakness and sensory disturbance of all extremities, bilateral facial weakness and dysphagia. On neurologic examination, there was bilateral weakness of the upper and lower facial muscles, bulbar palsy and severe distal weakness of all extremities. The deep tendon reflexes were absent and the sensation of touch, pinprick, temperature, and vibration was impaired bilaterally symmetrically in all extremities. Serum biochemistry revealed hyperproteinemia, hypergammaglobulinemia and elevated liver enzymes. Rheumatoid factor, antinuclear antibody anti-smooth muscle antibody were positive. Serological tests for hepatitis B surface antigen and its antibody hepatitis B core antibody, and hepatitis C antibody were all negative. Serum anti-GM1, anti-GD1b, anti-GQ1b and anti-MAG antibodies were negative. Liver biopsy findings were consistent with AI-CAH with marked lymphocytic infiltration in the portal tracts. Albuminocytologic dissociation was noted in CSF. Motorconduction velocity of the median, ulnar and facial nerves were markedly reduced with temporal dispersion. No motor response was evoked in the lower extremities. Needle electromyography revealed denervation and reinnervation potentials in the arm and leg. The sural nerve biopsy showed segmental de- and re-myelination and deposition of IgG components in endoneurium. Neurological symptoms and liver dysfunction improved with corticosteroid treatment. In this case, hypergammaglobulinemia associated with an exacerbation of AI-CAH may be responsible for the acute inflammatory demyelinating neuropathy through an unknown autoimmune mechanism.
