Among 17 patients with amyloid polyneuropathy type IV in a Japanese family, we found a 72-year-old woman, who showed extraocular symptoms approximately 10 years after the onset of the disease. she developed weakness of the right facial muscles and dysarthria at age 57. She had atrophy and disturbance of movement of the tongue, along with difficulty in swallowing at age 62. At the age of 66, she felt diplopia when she looked toward the left, followed by difficulty of ocular movement. These manifestations progressed and at age 72, she was found to have mild ptopsis, mild to moderate disturbance of almost all extraocular muscles, moderate to severe disturbance of facial, masseter, pharyngeal, tongue and neck muscles. She also had slight weakness and atrophy of the limb and truncal muscles together with slight loss of pain and vibratory sensations in the distal parts of the limbs. FAP IV has sometimes been called cranial amyloidosis, but motor disturbance is limited to the middle and lower cranial nerve territories in the majority of the reported cases, and manifestations of the extraocular muscles are quite rare. According to the present investigation of the world literature, this is the second case of FAP IV with extraocular muscle involvement.

We report a 63-year-old man with progressive gait disturbance and dysarthria. The patient was apparently well until the age of 62 (February, 1990) when he noted unsteadiness of gait. Two months later, dysarthria appeared. He was admitted to Juntendo Izunagaoka Hospital on April 23, 1990. Neurologic examination revealed a mentally sound man with normal higher cerebral functions. Cranial nerves were unremarkable except for scanning speech. His gait was ataxic with positive Romberg sign. No motor weakness was noted, however, he had hypotonia and cerebellar ataxia. Deep tendon reflexes were retained and the plantar response was flexor. Pain, touch and vibration senses were diminished in the distal parts of the lower extremities. Laboratory examination revealed a 2.5 cm mass in the left lung field. Cranial MRI revealed a small T1-low and T2-high signal intensity lesion in the left temporal lobe. Abdominal CT scan revealed multiple low density lesions in the liver. His subsequent course was complicated by progressive deterioration in his gait and loss of deep tendon reflexes. He expired on November 24, 1990. The patient was discussed in the neurological CPC and the chief discussant arrived at the conclusion that the patient had anti-Hu associated paraneoplastic encephalomyelitis and sensory neuropathy. Some other participants thought that the patient had carcinomatous cerebellar degeneration. Postmortem examination revealed a 4x4 cm mass lesion involving the left S4-S5 segments. Histologic examination of the tumor was small cell carcinoma. Many metastatic foci were found in the liver. The cerebral hemispheres were unremarkable except for a small wedge-shaped tissue defect in the left temporal lobe which appeared to have been caused by old head trauma which the patient had received. The cerebellar vermis showed slight enlargement of cortical sulci, however, the cerebellar hemispheres appeared unremarkable. Upon histologic examination, marked loss of Purkinje cells was noted, particularly in the cerebellar anterior lobe. The dentate nucleus showed slight cell loss with increase in fat granule cells. The inferior olive was normal. The histologic characteristics were consistent with the pathologic diagnosis of carcinomatous cerebellar degeneration. No evidence of limbic encephalitis was seen. The peripheral nerve was not examined.

Rapid-rate transcranial magnetic brain stimulation produces lateralized suppression of speech output over the frontal lobe, consistent with cerebral dominance for language. But the sensitivity of magnetic speech localization has been limited, and reports are imprecise concerning the amount of discomfort involved. Using a focal magnetic coil, we evaluated the effectiveness and pain of stimulation at different intensities, orientations, and repetition rates (2 to 32 Hz) in six normal volunteers. We obtained complete and clearly lateralized speech arrest in all subjects. The best ratio of efficacy to pain occurred using slower repetition rates of 4 to 8 Hz with a horizontal alignment of the induced electric field. Lower stimulation frequency also allowed clearer distinction between speech arrest and dysarthria from tonic contraction of cranial muscles. The relative comfort and safety of stimulation at 4 Hz should allow more widespread use of magnetic speech localization in clinical and research applications.

We report a 91-year-old man who had a stroke and died of renal failure. He had been treated for hypertension since 20 years before the onset of the present illness. In addition, he was operated on a gastric cancer 17 years previously. Otherwise he was doing well until May 29, 1991 (when he was 87-year-old) when he had sudden onset of dysarthria and right facial weakness. He was admitted to our hospital. On admission, general physical examination was unremarkable, and neurologic examination revealed a mentally sound man with slight dysarthria, right facial weakness, orolingual dyskinesia, and dysequilibrium in which he showed difficulty in tandem gait; however, no cerebellar ataxia was noted. A cranial CT scan revealed leukoaraiosis with multiple low density areas in the cerebral white matter. His BUN was 37 mg/dl and Cr 2.2 mg/dl. His neurologic symptoms cleared within the next few weeks and he was discharged with ticlopidine 100 mg q.d.. He had been doing well after the discharge except for gradual worsening of his renal function; his BUN was 65 mg/dl and Cr 3.27 mg/dl in April of 1994. On March 10, 1995, he fell down and hit his back; he became unable to walk because of pain, and he was admitted again on March 16, 1995. On admission, his blood pressure was 170/80 mmHg. There was an 1 + pitting pretibial edema; otherwise general physical examination was unremarkable. Neurologic examination revealed an alert and oriented man, however, Hasegawa's dementia scale was 23/30. Higher cerebral functions as well as cranial nerves were intact. He showed some unsteadiness of gait, however, no motor weakness or ataxia was noted. Deep tendon reflexes were diminished, but Chaddock sign was positive bilaterally. Vibration was diminished in the feet, however, pain and touch sensations were intact. Laboratory examination revealed a compression fracture of the twelfth thoracic vertebra. Blood count and chemistries were as follows; Hb 7.6 g/dl, Hct 23.3%, TP 6.0 g/dl, Alb 3.6 g/dl, BUN 87 mg/dl, Cr 4.53 mg/dl, T-Chol 174 mg/dl, HDL-Chol 49 mg/dl, Glu 156 mg/dl, Na 142 mEq/L, K 5.4 mEq/L, Cl 115 mEq/L. A urine specimen contained 1 + protein and 1 + glucose, and the sediments contained hyaline casts. A cranial CT scan was essentially same as that taken four years ago. His hospital course was complicated with pneumonia, congestive heart failure, and progressive renal failure. He was treated with intravenous fluid, chemotherapy, and other supportive measures, however, he expired from respiratory failure on April 30, 1995. He was discussed in a neurologic CPC, and the chief discussant arrived at the conclusion that the patient had Binswanger's disease in the brain, benign nephrosclerosis from arteriolosclerosis due to hypertension, congestive heart failure, and pneumonia. Opinions were divided regarding the question as to whether or not this patient had Binswanger's disease. Although his cranial CT scan revealed leukoaraiosis, his dementia and gait disturbance was only mild until his fall on March, 1995. Clinical features did not conform to those of Binswanger's disease. Postmortem examination of the right hemisphere revealed wide spread atherosclerosis and arteriolosclerosis. The kidney showed benign nephrosclerosis due to arteriolosclerosis. Sclerotic changes were also seen in the coronary arteries and the left middle cerebral artery with 70% stenosis. Myelin stain showed diffuse myelin pallor of the cerebral white matters with scattered small infarcts. Arterioles in the white matter showed arteriolosclerosis. Small infarcts were also seen in the putamen and in the thalamus. This patient appeared to have had circulatory disturbance of the white matter which is the basic abnormality causing Binswanger's disease. However, white matter changes in this patient were not quite severe enough to make a pathologic diagnosis of Binswanger's disease.

Medial medullary infarctions (MMI) were reported in less than 40 patients with satisfactory clinicotopographic documentation. We studied seven patients with MRI-proven acute MMI seen in two neurologic departments over a 5-year period (1990-1994). MMI represented less than 1% of ischemic strokes in the posterior circulation. Five patients had an infarction above the pyramidal decussation. All patients had contralateral hemiparesis and lemniscal sensory loss, accompanied by ipsilateral lingual palsy (Dejerine's syndrome) in three. Two patients had infarction below the pyramidal decussation, with ipsilateral hemiparesis and lemniscal sensory loss. Accompanying symptoms and signs of MMI were vertigo and nausea (n = 5), mild ipsi- or contralateral decrease in pain sensation (n = 6), headache (n = 4), ipsilateral limb ataxia (n = 6), contralateral truncal lateropulsion (n = 5), mild ipsilateral ptosis (n = 4), nystagmus (n = 4), dysarthria (n = 3), and somnolence (n = 2). Presumed causes of MMI were stenosis, occlusion or dissection of the ipsilateral vertebral artery (n = 5), and cardioembolism (n = 1). Outcome at 3 months was favorable in five patients. In conclusion, the clinical features of MMI are more heterogeneous than commonly thought, whereas its etiology seems fairly constant (vertebral artery disease).

Several symptom complexes in multiple sclerosis (MS) are found in unusual circumstances but are characteristic of the disease. Most of these are amenable to treatment and will be confronted by the physiatrist treating patients who have MS. This article begins by addressing paroxysmal symptoms such as trigeminal neuralgia, paroxysmal dysarthria and ataxia, parathesia and pain, paroxysmal itching, and akinesia. Seizures, adventitious movements, fatigue, and complications related to pregnancy also are addressed.

A 74-year-old woman was admitted because of abdominal pain. A few weeks before this admission she had had a cerebral infarction in the right hemisphere, reflected by a left sided paralysis, dysarthria, depression and a slight cognitive disorder. The night before admission she woke up from a sharp, continuous pain in the right upper abdomen. Physical examination disclosed pain in the right upper abdomen on palpation. Laboratory tests showed a slight elevation of all 'liver' enzymes. A differential diagnosis of cholecystitis or pyelonephritis was made. Additional tests did not confirm either of these diagnoses. Because of immobilisation pulmonary embolism was then suspected. This diagnosis was confirmed by scintigraphy. The patient was treated and made a full recovery. Diagnostic errors can be made by faulty triggering and omitting verification. The diagnostic strategy for pulmonary embolism is a ventilation perfusion scan, which is followed in case of a non high-probability result by pulmonary angiography. It is emphasized that the presentation of pulmonary embolism can be aspecific.

Adult motor neuron disease (amyotrophic lateral sclerosis [ALS]) is a neurodegenerative disorder characterized by loss of motor neurons in the cortex, brain stem, and spinal cord, manifested by upper and lower motor neuron signs and symptoms affecting bulbar, limb, and respiratory musculature. Clinically, the disease course is characterized by progressive weakness, atrophy, spasticity, dysarthria, dysphagia, and respiratory compromise, ultimately resulting in death or mechanical ventilation in the vast majority of patients. Patterns of presentation and pathological features of the disease, along with clinical and electrophysiologic criteria for diagnosis, are discussed in this review. Since 8% to 22% of patients survive more than 10 years without ventilator use, meticulous medical and rehabilitation management is extremely important to ensure optimal health and quality of life in these patients. Major issues in the care of individuals with ALS include weakness and spasticity, impairments in activities of daily living and mobility, communication deficits and dysphagia in those with bulbar involvement, respiratory compromise, fatigue and sleep disorders, pain, and psychosocial distress. Research in ALS changes rapidly, but is currently focused on potential etiologic factors such as glutamate excitotoxicity, role of oxidative stress, autoimmunity to calcium channels, and cytoskeletal abnormalities, as well as related treatment initiatives including glutamate modulators, neurotrophic factors, antioxidants, antiapoptotic factors, and gene therapy. Recently, mutations in the gene encoding Cu/Zn superoxide dismutase were identified in a subset of familial ALS patients. Riluzole, a glutamate antagonist and Na-channel blocker, became the only drug currently approved for treatment of ALS after studies showed a small positive effect on survival. Until a definitive treatment or cure for ALS is found, the multifaceted rehabilitation team approach remains the best hope for improving health and survival in this devastating illness.

The patient was a 72-year-old man who had a history of subtotal gastrectomy for gastric ulcer at age of 37 years. He had no familial history of hereditary disorders. In 1980 he noticed mild ataxic gait which exaggerated while he closed eyes. The symptoms increased gradually, and four years later he noticed hypoesthesia of his soles. In 1983 he was admitted to the National Center Hospital for Mental, Nervous and Muscular Disorders for the first time. Neurological examination revealed dysarthria, ataxic gait, disturbance of coordination to a slight degree, and muscle strength of the upper and lower limbs were in normal range. Mild hypoesthesia of pain and temperature sensation, and marked decrease of deep sensation and vibration of the lower extremities were demonstrated. Romberg sign was positive. EMG studies revealed low amplitude of action potential and normal motor nerve conduction velocity. Biopsy of the sural nerve showed marked decrease of both large and small myelinated fibers. In 1998 he was admitted second time for the further examination. Laboratory examination including routine blood examination, blood chemistry including CRP, TPHA, vitamin B1, B2, B12, A, E, K, hexosaminidase A in leucocyte were in normal range. CSF was normal. Genetic studies including SCA 1, 2, 3, 6, DRPLA, CMT1A, CMTX 1 were all negative. MCV of lower limbs was in normal range, though SCV was not evoked in the upper and lower limbs. MRI studies showed mild atrophy of the bilateral lobulus of the cerebellum which was not so much changed in the last 5 years. The clinical symptoms revealed dominant posterior column disturbance, ataxia and sensory neuropathy. These combination was not described in the previous literature, and this case may be a new variant of the spinocerebellar degeneration.

A 67-year-old man with right hemiparesis and dysarthria was admitted with right hemiparesis involving the face, hyperpathia, numbness and pain of the right body and limb except the face, and had hyperreflexia and pathological reflex in the right limb. Brain MRI on the day after admission disclosed no lesion which might explain the symptoms. Short latency somatosensory evoked potential showed a low amplitude after P14 when the right side was stimulated. Cerebral angiography revealed occlusion of the left vertebral artery. Brain MRI on the 18th hospital day disclosed left medial medullary infarction, so we diagnosed medial medullary syndrome. This case was hard to diagnose, because of the atypical features and the absence of an abnormal lesion on the initial MRI.
