The authors report a case with two mycotic aneurysms in the cavernous portion of the internal carotid artery, presumably secondary to a transient bacteremia from pneumonia. The strikingly rapid development of the aneurysms was demonstrated by angiography. Painful total ophthalmoplegia and extophthalmos were the main clinical features.

For the first time in Germany cases of a "centronuclear myopathy" are described in a 14-year-old boy and his 18-year-old sister. First symptoms in both patients appeared at 4 to 5 years of age with a "sleepy facial expression", clumsy gait and rapid fatigue. Within few years the disease progressed to generalized muscle weakness and atrophy, ptosis, ophthalmoplegia externa and areflexia. Weakness and atrophy were most pronounced in the distal muscles of the lower extremities. Both patients were free of epilepsy and the EEG recordings were normal. Motor and sensory nerve conduction velocities were normal. Repetitive stimulation of nerves revealed a normal transmission from nerve to muscle. Muscle biopsy showed a type I muscle fiber hypotrophy and a type II muscle fibre hypertrophy in addition to a predominance of type I fibres. Both fibre types showed central nuclei, sometimes appearing as chains in longitudinal sections. In most cells with central nuclei there persists a very small pericentral zone free of myofibrils but with increased activity of oxidative enzymes and phosphorylase. 2--3% of muscle fibres in cross sections showed a decreased of absent enzyme activity in the most peripheral fibre zone. Electron microscopy showed evidence of a centrally distinct myofibrillar disintegration. The father of both children had a ptosis at least from the 20th year of age. 5 years later generalized progressive muscle atrophy was recorded. Aged 51 years he died of pneumonia. Though not proved most probably the father suffered from the same disease as the children, pointing to an autosomal dominant inheritance in this family. The disease, according to the literature, seems to be genetically heterogeneous. The clinical picture seems to be independent of the mode of inheritance. Our patients showed a relatively rapid progression of symptoms. Pathogenetically the "centronuclear myopathy" may result from a disturbance of correlated nerve-muscle structures starting during early fetal life.

A 72-year-old man developed supranuclear ophthalmoplegia, bradykinesia, rigidity, unsteady gait, dementia, dysphagia, retrocollis, grasp reflex and apraxia of eyelid opening. These findings were compatible with progressive supranuclear palsy (PSP). At the age of 66, he presented a peculiar phenomenon characterized by simultaneous tonic contraction of the orbicularis oris muscle (OOM) and the palatal muscles elicited by pronouncing "pa", which resulted in difficulty of voluntary opening of the mouth and the rhinopharynx. Therefore, the respiration air reciprocated between the lung and the closed mouth. The expiratory pressure puffed out the cheeks, while the lips remained tightly closed. While the respiratory movements and the pressure increased by degree, the OOM contracted more strongly in proportion to the pressure. Sixty to ninety seconds after the elicitation, the pressure overcame the contraction of the OOM and the course of the phenomenon was completed. The electromyograms showed that the OOM activity was prolonged after initial voluntary contraction, remaining thus after a tracheostomy for pneumonia at the age of 72, and that it increased in response to the pressure. Apraxia of eyelid opening, one of the other symptoms, resembled this phenomenon in terms of the aspect of difficulty of voluntary mouth opening. The "holding" phase of grasp reflex, yet another symptom, resembled it in the recruitment of the OOM activity. The phenomenon is not common in patients with PSP. However, we concluded that it may be included among the symptoms of PSP because it has similar characteristics to apraxia of eyelid opening and grasp reflex, which are not uncommon in patients with PSP.

An autopsy case of progressive supranuclear palsy (PSP) associated with central pontine myelinolysis (CPM) is reported. A 73-year-old male patient suffered from gait disturbance for about 5 years. The clinical features were characterized by gradual development of supranuclear ophthalmoplegia, tremor, bradykinesia, rigidity, neck dystonia, dementia and pseudobulbar palsy at the advanced stage of his illness. Treatment with levodopa did not improve his neurological signs and symptoms. PSP or multiple system atrophy was considered as a clinical diagnosis of the patient. He died of pneumonia, acute pancreatitis and liver dysfunction in November 1985. The main neuropathological findings were neuronal loss and gliosis with neurofibrillary tangles of globose type in the globus pallidus, subthalamic nucleus, substantia nigra and dentate nucleus, and at the base of the pons, bilateral and symmetrical demyelination was found. In addition, myelin staining revealed circumscribed pallor in the cerebral white matter. The histologic diagnosis was PSP associated with CPM. An association of PSP with CPM is rare in the elderly and possible etiologic factors of both diseases were discussed.

Clinical and postmortem findings of a case that had combined alcoholic pellagra encephalopathy and Wernicke disease are described. This 51-year-old malnourished and chronic alcoholic man presented with progressive mental deterioration, pellagra dermatitis, hypertonus of the neck and other musculatures, myoclonic jerks with bizarre involuntary movements, in addition to total external ophthalmoplegia and gait disturbance. After administration of multivitamins, including thiamine and nicotinamide, these neurologic abnormalities were dramatically improved in a few days. However, the patient died thereafter because of sepsis associated with pneumonia. Postmortem examination revealed marked abnormalities in CNS, characterized by diffuse atrophy of gray matter and widespread neuronal degeneration and characteristic central chromatolysis in pontine nuclei, dentate nuclei, cranial nerve nuclei in the brain stem, Betz cells of the cerebral cortex, and Clarke's column and anterior horn cells of the spinal cord. There were also atrophy and gliosis of the mammillary bodies, degeneration and vascular proliferation of periaqueductal gray matter, and massive gliosis around the third ventricle. These neuropathological changes were compatible with symptoms of both alcoholic pellagra encephalopathy and Wernicke's disease, but they were also strongly suspected on clinical grounds.

We report the clinical and neuropathological findings in an autopsy case of progressive dementia, Parkinsonism, pseudobulbar palsy and supranuclear ophthalmoplegia. Since 70 years old, this hypertensive patient developed forgetfulness, unsteady gait and festination. These symptoms rapidly worsened and he was admitted in October 1983, at age 71. He had severe dementia and showed stiff face. Voluntary vertical movement of the eyes was severely disturbed, but reflex vertical movement by the doll's head eye maneuver was not affected. Muscle tone in the limbs increased slightly, and deep tendon reflexes were hyperactive in jaw and the upper extremities. Babinski sign was negative bilaterally. Sensation and coordination remained normal. Although he was not paretic or ataxic, his movements were very slow. He could not stand by himself and easily fell backward. These clinical features resembled those of progressive supranuclear palsy except for severe dementia and rapid progression. Brain CT scan revealed marked dilatation of the lateral ventricles, prominent periventicular lucency and atrophy of brainstem and cerebral cortex. Treatment with levodopa slightly improved his movement, but difficulty in swallowing worsened increasingly. He died of hypoglycemic coma and aspiration pneumonia in September 1984, about two years after the initial symptoms. General autopsy showed severe pneumonia and atrophy of the liver. The brain weighed 1,210g. Atherosclerotic change in the cerebral arteries were mild. Coronal sections of the cerebral hemispheres revealed diffuse ischemic change and multiple small infarctions in the bilateral cerebral white matter. Cortical atrophy was observed in the cerebral hemispheres. The basal ganglia, thalamus, and pons showed status lacunaris. Atrophy of midbrain and depigmentation of the substantia nigra were observed macroscopically.

A new patient with Leigh's syndrome (subacute necrotizing encephalomyelopathy due to pyruvate dehydrogenase complex deficiency) is presented. A Turkish boy of consanguinously married healthy parents developed progressive muscle weakness since infancy. At the age of 3 years he was unable to sit, stand or walk. Clinical examination showed general muscle weakness, hypotonia, muscle hypotrophy, bilateral ptosis, partial bilateral external ophthalmoplegia, nystagmus, intention tremor and hypoactive tendon reflexes. The EEG showed diffuse slowing, the cerebral CT scan disclosed mild hydrocephalus e vacuo. Motor nerve conduction velocity was slightly decreased, the EMG revealed signs of neuropathy. In the biopsied muscle only a mild hypotrophy of type 2 fibres was found, no abnormal mitochondria could be detected. The sural nerve was slightly abnormal: loss of large myelinated axons, loss of unmyelinated nerves. CSF protein was elevated to 80 mg/dl, protein electrophoresis revealed the pattern of markedly impaired blood-CSF barrier. Serum lactate and pyruvate were permanently elevated. In the urine the excretion of alanine was raised. The clinical state deteriorated during intercurrent infections; somnolence, vomiting and Cheyne-Stoke's respiration occurred. At the age of 3 1/2 years the child died of pneumonia. In the liver tissue a decreased activity of the pyruvate dehydrogenase complex was found. Neuropathological examination of the brain demonstrated wide-spread changes of Leigh's spongiform encephalopathy. Several enzyme deficiencies have hitherto been associated with Leigh's syndrome: This patients confirms earlier findings that a subgroup of Leigh's syndrome is caused by pyruvate dehydrogenase complex deficiency.

We report an unusual autopsy case of corticobasal degeneration. The patient was male who was 67 years old at the time of his death. He developed clumsiness of his right hand at age 65. Neurological examination at age 66 revealed supranuclear ophthalmoplegia of upward gaze and parkinsonism. Progressive supranuclear palsy was suspected. The patient's clinical course was rapidly progressive. Dementia developed nine months after the onset of the disease, and the patient manifested apallic syndrome at 21 months and died of pneumonia at about 25 months. At autopsy the brain weighed 1370g. Macroscopic examination revealed prominent atrophy of the anterior and parietal lobes, particularly of the pars opercularis in the left inferior frontal gyrus, and there was marked depigmentation of the substantia nigra. Histological examination showed neuronal loss, glial proliferation, spongy state, and ballooned neurons in the frontal and parietal lobes. Neuronal loss with glial proliferation was conspicuous in the striatum, pallidum, thalamus, and substantia nigra. There was slight neuronal loss in the dentate nucleus and locus ceruleus. Staining by Gallyas-Braak method revealed massive appearance of argyrophilic threads. This case is important in terms of the clinical differentiation from progressive supranuclear palsy, and is also interesting in regard to the pathological correlation with slowly progressive aphasia.

Hemodialysis(HD) patients are at risk for thiamine deficiency because of low intake and accelerated loss of thiamine during HD. We report here an HD patient, an 82-year-old woman, who developed acute encephalopathy due to thiamine deficiency with hyperammonemia. She was admitted to Nishikawa Town Hospital due to pneumonia and was treated with ABPC/SBT for one week. While she was cured of pneumonia, she had a persistently poor appetite. On the twenty-fourth day after admission, HD with intradialytic parenteral nutrition(IDPN), which consisted of 10% glucose 500 ml, in order to correct her malnutrition, was started. She suddenly presented confusion, speech disturbance and ophthalmoplegia. HD with IDPN was stopped after two hours because of her symptoms. Laboratory studies disclosed plasma glucose of 186 mg/dl and serum ammonium of 155 micrograms/dl. Arterial blood gas analysis(inhaling 3 l/min O2) showed severe metabolic acidosis and respiratory acidosis (pH 7.138, pCO2 44.8 mmHg, pO2 108.9 mmHg, HCO3- 15.1 mmol/l). Her malnutrition, unexplained metabolic acidosis and neurological presentation raised the suspicion of acute encephalopathy due to thiamine deficiency. Fursultiamine 100 mg was administered intravenously. After two hours, metabolic acidosis disappeared (pH 7.437, pCO2 33.9 mmHg, pO2 161.0 mmHg, HCO3- 22.9 mmol/l), and she regained her clear consciousness and serum ammonium decreased at 16 micrograms/dl on the next morning. Serum lactate and thiamine level were shown later to be 57.5 mg/dl and 27 nmol/l, respectively. Her clinical course suggests that the glucose load including IDPN may have caused deterioration of the neurological disorder under the condition of thiamine deficiency. Furthermore, it is possible that a relationship exists between thiamine deficiency and hyperammonemia.

Bickerstaff's brainstem encephalitis (BBE) is a rare diagnosis different from meningoencephalitis with ophthalmoplegia, ataxia and confusion. Less than 100 cases have been described in the literature. We described the fatal case of a 69-year-old man who presented a severe consciousness disorders, distal weakness in the four limbs, and the BBE triad a few days after his admission for pneumonia.
