RESUMEN
We report an 80-year-old Japanese woman who presented levodopa-responsible parkinsonism followed by progressive dementia. She was well until her 61 years of age (in 1978) when she noted onset of resting tremor in her right hand followed by tremor in her right leg. She was treated with levodopa and trihexyphenidyl with good response, however, later on, she suffered from gait disturbance. In 1985, she had an episode of cardio-pulmonary arrest from which she was resuscitated, however, she started to show hypermetamorphosis, memory defect, and aggressive behaviors. She also developed motor fluctuations and dyskinesias from levodopa. She was admitted to our service in 1986; she showed rather typical parkinsonism and mild dementia. She received left Vim thalamotomy in the same year. Her dyskinesias improved, however, her gait disturbance became progressively worse. In 1995, she was admitted to our service again; she showed marked dementia and advanced parkinsonism; she was unable to walk unsupported. She became bedridden in 1996 and gastrostomy was placed. She was transferred to Zushi Aoki Hospital. Her dementia became progressively worse, and she was in the akinetic and mute state. She expired on April 22, 1998. She was discussed in a neurological CPC. The chief discussant arrived at a conclusion that the patient had Parkinson's disease with complication by Alzheimer's disease in her later clinical course. The diagnoses of participants were divided among Parkinson's disease with dementia, Parkinson's disease and Alzheimer's disease, and diffuse Lewy body disease. Postmortem examination revealed marked neuronal loss in the substantia nigra and the locus coeruleus. Lewy bodies were found in the substantia nigra. In addition, rather many Lewy bodies of cortical type were seen in the cingulate gylus, inferior temporal gylus, and in the amygdaloid nucleus. These Lewy bodies were positive for alpha-synuclein. Also, tau-positive intra-neuronal tangles were seen in the hippocampus and in the substantia nigra. The Meynert nucleus showed marked neuronal loss. Pathologic findings were consistent with the diagnosis of diffuse Lewy body disease.

We report a 61-year-old Japanese man who died of complications of esophagus cancer surgery. He was well until his 55 years of the age, when he had an onset of speech disturbance and hand writing. He was seen by a neurologist who prescribed Menesit 600 mg/day. His symptoms improved with this medication. In 1993, three years after the onset, he started to show gait disturbance and easy to fall. In 1995, he noted difficulty in eye opening. He visited our clinic on October 26, 1996. On examination, he showed vertical gaze paresis, masked face, nuchal rigidity, small step gait, freezing phenomena, and festination. His mental status was normal. He was treated with 800 mg/day of Menesit, 800 mg/day of L-dops, and 10 mg/day of bromocriptine with little improvement in his symptoms. Cranial CT scan revealed some dilatation of the third ventricle. Subsequent clinical course was one of the slow progression of his parkinsonism. In September of 1997, he noted difficulty in swallowing. He was admitted to the gastrointestinal service of our hospital on October 14, 1997. On admission, neurologic status was essentially similar to the previous one, but he showed more advanced state of his parkinsonism. Upper gastrointestinal series revealed a mass lesion of about 11.5 cm in length protruding into the lower esophagus lumen. Subtotal esophagus resection including the mass was performed on December 2, 1997. The stomach was elevated for anastomosis with the upper esophagus. No metastases were found in the mediastinum except for two lymph nodes in the para-esophageal region. The subsequent course was complicated by marked elevation of GOT, GPT, LDH, total bilirubin as well as direct bilirubin, alkaliphosphatase, and amylase starting in the evening of the surgery. On December 7, leukocytosis and pneumonic shadow were seen involving his right lung. On December 10, he developed cardiopulmonary arrest. He was once resuscitated; however, he developed cardiac arrest again seven hours later and pronounced dead. He was discussed in a neurologic CPC. The chief discussant arrived at the conclusion that the patient had PSP and the cause of the death was ascribed to circulatory disturbance to the liver. The discussant also thought that the terminal course was complicated by cholangitis or cholecystitis, sepsis, and pulmonary embolism. Surgical specimen of the esophagus tumor revealed carcinosarcoma. Postmortem examination revealed yellowish discoloration of the peritoneum and mesenterium, and accumulation of clouded ascites indicating the presence of peritonitis. Inflammatory change extended to the mediastinum. On microscopic examination, various kinds of bacilli and candida spores were seen. The liver was enlarged and a perforation was noted in the gallbladder causing biliary necrosis in the adjacent liver. An extensive infarct was seen in the left lobe of the liver; this was found to be due to obstruction of the hepatic artery at the site of the duodenohepatic mesenterium and obstruction of intrahepatic portal vein secondary to retrograde intrahepatic cholangitis in the left lobe. A piece of surgical threads was seen adjacent to the hepatic artery; foreign body granulomatous reaction was seen surrounding the surgical thread. The rupture of the gallbladder appeared to be due to the obstruction of the left branch of the hepatic artery. Neuropathologic examination revealed extensive degeneration of the pallidum, the substantia nigra, and the subthalamic nucleus and presence of neurofibrillary tangles in the remaining neurons. The neuropathologic findings were consistent with progressive supranuclear palsy, although the pathologic changes in the midbrain tegmentum was only mild gliosis.

A 50-year-old man was admitted suffering from severe anemia and renal dysfunction. He had been admitted for the first time at the age of 49, and was diagnosed with multicentric Castleman's disease (MCD) and secondary amyloidosis. At that time, marked erythroid hypoplasia was demonstrated by both aspiration and biopsy of bone marrow. A diagnosis of pure red-cell aplasia (PRCA) was made. Immunosuppressive agents improved his symptoms and laboratory data. We report here a very rare case of PRCA following MCD and amyloidosis, and with reference to the literature, we discuss the relation between MCD and related diseases.

We report a 64-year-old Japanese woman who died one year after the onset of progressive gait disturbance and dementia. She noted a difficulty in holding a glass and hand tremor in June of 1996 when she was 63 years old. In July of 1996, she tended to lean toward left when she walked. She also noted truncal titubation. In November of 1996, she started to have visual hallucination and delusion in which she said "I see something is flying on the wall.", "Somebody has come into my room", and things like that. She was admitted to our service on November 22, 1996. On admission, she was alert and general physical examination was unremarkable. Neurologic examination revealed disturbance in recent memory. Hasegawa's dementia rating scale was 22/30. She showed vivid visual hallucination with colors in which she saw faces of dwarfs and angels, a space ship, and others. Higher cerebral functions were normal. She showed left oculomotor palsy which was a sequel of an aneurysm and subarachnoid hemorrhage nine years before. Otherwise cranial nerves were unremarkable. She showed ataxic gait, limb ataxia, truncal titubation, and postural hand tremor. She had no weakness and no muscle atrophy. Deep tendon reflexes were within normal limits. Plantar response was flexor. Sensation was intact. Laboratory examination was also unremarkable. Complete survey for occult malignancy was negative. CSF was under a normal pressure and cell count was 1/microliter, total protein 27 mg/dl, and sugar 68 mg/dl. Cranial CT scan was unremarkable. MRI was not obtained because of the presence of an aneurysm clip in the left internal carotid-posterior communication artery junction. She showed progressive deterioration in her mental function. By January 1997, she became unable to stand or walk with marked dementia. Repeated CSF exams and cranial CT scans were unremarkable. She suffered from several episodes of aspiration pneumonia. A trial of three days methylprednisolone pulse therapy was given starting on March 7, 1997, which was of no effect on her neurologic status. On March 28, 1997, she was intubated because of acute respiratory distress syndrome. In April 2, her body temperature rose to 38 degrees C. On April 9, 1997, her blood pressure dropped and resuscitation was unsuccessful. She was pronounced dead on the same day. The patient was discussed in a neurologic CPC and the chief discussant arrived at the conclusion that the patient had primary leptomeningeal lymphoma. Other possibilities entertained among the audience included brain stem encephalitis of unknown type, carcinomatous cerebellar degeneration plus limbic encephalitis, Creutzfeldt-Jakob disease, thalamic degeneration, and progressive multifocal leukoencephalopathy. Post-mortem examination revealed thickening and clouding of the leptomeninges; Gram-positive diplococci were found in the leptomeninges. This meningitis appeared to have been an complication in the terminal stage of her illness. Microscopic examination revealed astrocytosis in the midbrain tegmentum. Cerebral cortices showed only mild astrtocytosis. No cerebellar atrophy was seen and Purkinje cells were retained which excluded paraneoplastic cerebellar degeneration. Neuropathologic diagnosis was bacterial meningitis, however, the presence of brain stem encephalitis prior to the onset of bacterial meningitis could not be excluded. It is interesting to note that the diagnosis of the primary neurologic disease of this patient was not easy even after autopsy. As autopsy permission was obtained only for the brain, it was not clear whether or not this patient had an occult malignancy somewhere in her body, however, there was no evidence to indicate paraneoplastic degeneration of the central nervous system. As the patient did not have meningeal signs until one month before her death, it is difficult to ascribe her entire neurologic problems to her meningitis. Finally, her visual hallucination was vivid and colorful; we thought this might have been

We report an 81-year-old woman who presented with motor disturbance in her right hand which was followed by parkinsonism, dementia, and supranuclear gaze palsy. She was well until her age of 73 (1989) when she had an onset of difficulty in using her right hand; she did not have weakness. She also developed small step gait. These symptoms had progressively become worse. She was admitted to our hospital in July of 1992 when she was 75 years old. On admission, she was alert and oriented, but she showed some difficulty in recent memory. She did not have aphasia or ideomotor apraxia, but she showed limb-kinetic apraxia in her right hand, ideational apraxia, dressing apraxia, constructional apraxia, tactile agnosia, and left-right disorientation. Alien-hand syndrome was observed in her right hand. Ocular movement was within normal limit for her age. She had oro-lingual dyskinesia. Otherwise, cranial nerves were intact. She walked in small-steps. She had rigidity and fine myoclonic movements in her right upper extremity. Deep reflexes were within normal limits and symmetric. Superficial and deep sensations were intact. Laboratory findings were unremarkable. She was discharged on August 15, 1992 for outpatient follow-up. Her motor and mental symptoms were progressive. By October of 1992, she developed supranuclear vertical gaze palsy, marked rigidity in the neck, and astereognosis. By June 1993, she became unable to walk without support. MRI taken in May of 1994 revealed atrophy of insular cortices, temporal lobe tips and parietal lobes more on the left side; the third ventricle was slightly dilated. She was admitted to another hospital on June 30, 1994. She had become a bed-ridden state with marked dementia and dysphagia. She developed fever on November 5, 1996 and expired on December 16 of the same year. She was discussed in a neurological CPC and the chief discussant arrived at the conclusion that the patient had corticobasal degeneration. Other diagnoses entertained included progressive supranuclear palsy, pallidonigroluysian atrophy, diffuse Lewy body disease, and Pick's disease. But the most of the participants agreed with the chief discussant's diagnosis. Post-mortem examination revealed aspiration pneumonia in the lungs and liver fibrosis apparently due to viral hepatitis. In the central nervous system, frontal and parietal lobes were atrophic more on the left side. Atrophy was accentuated in the superior frontal gyri, precentral and postcentral gyri, and superior and inferior parietal lobuli. Neuronal loss and astrocytosis were seen in these regions with scattered ballooned neurons. The substantia nigra showed marked neuronal loss and gliosis; neuronal loss was also seen in the pars reticulata. The outer and inner segments of globus pallidus and the periacqueductal gray matter showed gliosis, however, no apparent neuronal loss was seen. Putamen, subthalamic nucleus, and the dentate nucleus were preserved. Pathologic changes were consistent with the diagnosis of corticobasal degeneration. It was interesting to note that anti-tau immunostaining and Gallyas staining revealed neuropil threads and astrocytic plaques in the cortical areas, and intracytoplasmic inclusion bodies in the cortical neurons; these inclusions were not stained by Bodian stain. Tuft-shaped astrocytes which may be seen in progressive supranuclear palsy were not observed in this patient. Although corticobasal degeneration and progressive supranuclear palsy share some neurological features in common, this patient showed typical pathologic changes of corticobasal degeneration.

We report a 49-year-old man with progressive bulbar palsy and respiratory failure. He was well until his 48 years of the age (December 1994) when he noted a difficulty in speaking in loud voice. In February, 1995, he noted regurgitation of foods to his nose and difficulty in his speech. He was admitted to our service in May 29, 1995. On admission, he was alert and oriented to all spheres and he was not demented. His higher cerebral functions were normal. In cranial nerves, he showed dysarthria and dysphagia; muscle atrophies were seen in the tongue, the bilateral sternocleidomastoid, supraspinatus, and infraspinatus muscles. Fasciculations were seen in these muscles. He showed no muscle weakness in his limbs except for the upper limb girdle muscles, no ataxia, no reflex abnormalities, nor sensory changes. EMG showed neurogenic changes in the affected muscles. MRI of the brain and the spinal cord was entirely normal. He was discharged for out patient follow-up, however, in October of 1995, he noted difficulty in swallowing solid foods. Gastrostomy was placed and he was discharged to his home. In February 11th of 1996, he was found unresponsive and brought into the ER of our hospital. On admission, he was comatose without spontaneous respiration. BP could not be obtained. He was immediately intubated and artificial ventilation was started. On the following morning, he became alert and he was not demented. He continued to show marked dysarthria and dysphagia; again no weakness was noted in the distal parts of the upper and lower extremities. Laboratory examination showed increase in serum CK to 2,173 IU/L and amylase to 2,032 IU/L. He was extubated on February 15th, however, his spontaneous respiration was not suffice to maintain his blood gas. According to his will, he was not placed on respirator and he died on February 24th, 1996. The patient was discussed in a neurological CPC and the chief discussant arrived at the conclusion that the patient had ALS. Although no upper neuron signs were observed clinically, it is not uncommon to see degeneration in the corticospinal tract in post-mortem examination. The question was what might have been the cause of increase in CK and amylase. Many participants thought that they were secondary to multiple organ failure due to prolonged hypoxic state at his last admission; other possibilities raised included acute myocardial infarction and acute bowel necrosis. Post-mortem examination revealed muscle atrophy in the facial, lingual, cervical, intercostal, and the upper limb girdle areas. The lungs were unremarkable except for old organized pneumonic foci in the right middle and lower lobes. Marked to moderate congestion was seen in many internal organs, however, no other gross abnormality was found. It was thought that respiratory palsy itself was the direct cause of his agonal event. In the spinal cord, the anterior horns showed various degree of neuronal loss and gliosis. No clear evidence of pyramidal tract degeneration was seen at the light microscope level. Lower brain stem motor neurons were markedly reduced. But no Bunina body was found. The substantia nigra showed moderate degree of neuronal loss and extraneuronal neuromelanins. The locus coeruleus showed similar but milder changes. The degree of nigral degeneration appeared to be well beyond those which could be seen in usual ALS patients. The question was whether or not this patient might have been in an early stage of the extended form of ALS.

The effect of cholinergic blockade on suppressed growth hormone (GH) secretion caused by feeding or the intraruminal infusion of an acetate, propionate, and butyrate mixture (107 and 214 mumol.kg-1.min-1 over 6 h) was examined in ovariectomized ewes. Intraruminal infusion at the rate of 107 mumol.kg-1.min-1 increased peripheral plasma short-chain fatty acid (SCFA) concentrations to approximately the physiological levels noted after feeding. Plasma GH was markedly suppressed by feeding and at both the 107 and 214 mumol.kg-1.min-1 SCFA infusion rates; however, cholinergic blocking agents completely blocked the suppressed GH secretion after feeding and only at the 107 mumol.kg-1.min-1 infusion rate. Plasma glucose increased at both infusion rates, and the plasma free fatty acids decreased after feeding and at both infusion rates. However, both metabolites were unchanged relative to the saline control after the injection of the cholinergic antagonists. It is suggested that the decrease in plasma GH observed after feeding and a near-physiological ruminal SCFA increment is mediated via the parasympathetic nerve and not by pharmacological ruminal SCFA increments attributed to other pathways.

Effects of somatic mutations in Ig variable region genes on the affinity maturation of autoantibodies were investigated using single precursor B cell-derived anti-double-stranded DNA mAb generated from an autoimmune disease-prone (NZB x NZW)F1 mouse. Analyses of DNA sequences, homology modeling on a graphic computer and molecular dynamics simulation of antigen-binding sites showed that any single site of mutation and changes in the electrostatic or hydrogen-bonding potential of the residues and in the three-dimensional structure could not solely explain the difference in DNA-binding activities. However, a significant increase in the flexibility of antigen-binding Fv loops, particularly VL CDR1 and VH CDR3, was associated with affinity-maturated anti-DNA antibodies. Such high flexibility of the FV loops may provide the environment where the antibodies could effectively interact with antigen DNA, a model consistent with the 'induced-fit' hypothesis of antigen-antibody interactions.

We report a 56-year-old woman with parkinsonism and dementia who died of respiratory failure. The patient was well until the age of 41 when she noted insidious onset of difficulty in moving around. Soon after, she noted tremor in both her hands and gait disturbance. She received stereotaxic right thalamotomy when she was 46-year-old; after thalamotomy, improvement was noted in her tremor, rigidity, and in gait. However, a few months later, she started to experience motor fluctuations with worsening of her symptoms in the afternoon. This worsening was temporarily relieved by increasing her levodopa/benserazide dose. She started to show visual hallucination and agitation when she was 54-year-old. Her symptoms had progressively become worse with marked motor fluctuations and she was admitted to our hospital when she was 56-year-old. On admission, she was alert and general physical examination was unremarkable. Neurologic examination revealed that she was disoriented to time and place; memory was markedly disturbed and calculation was poor. Hasegawa dementia scale was 7/30. Higher cerebral functions appeared intact. She showed masked face, small voice, and some dysphagia. Other cranial nerves were intact including ocular movements. She was unable to walk by herself; when supported she walked in small steps with marked disturbance in the righting reflex. Mixed rigidity and Gegenhalten was noted in her four limbs and in the neck. Tremor was absent. She showed marked akinesia.(ABSTRACT TRUNCATED AT 250 WORDS)

Molecular events occurring during the process of generation of pathogenic immunoglobulin (Ig)G anti-DNA antibodies in systemic lupus erythematosus (SLE) were studied using a newly established method. We analyzed the Ig variable (V) region gene sequence and DNA-binding activity of IgM and IgG anti-DNA monoclonal antibodies (mAb) from individual SLE-prone (NZB x NZW) F1 mice. The first event appeared to be clonal selection and expansion of IgM anti-DNA clones, in which several clones had intraclonal V gene mutations. Although the number of mutations was small, the mutated IgM clones were associated with an increase in DNA-binding activity. The somatic mutations located in complementarity-determining regions (CDR) and in framework regions (FR) of V genes were apparently related to changes in DNA-binding activity. IgG anti-DNA clones that progressively increased in number with aging had numerous somatic mutations in the V region genes and there was a pair of clones which showed an intraclonal accumulation of mutations, in association with increase in the DNA-binding activity. All these findings show that somatic mutations associated with affinity maturation of the V region begin immediately before isotype-switching from IgM to IgG of the clones that have been selected and expanded, in an antigen-driven manner and/or by other forces. We propose that further accumulations of intraclonal somatic hypermutation, in association with selection and expansion of high affinity IgG clones, may lead to formation of highly pathogenic anti-DNA antibodies.

This study was designed to evaluate the most effective administration method of NCS for advanced carcinoma of the stomach, mainly nonresectable and/or recurrent cases which were collected by our cooperative study group. Nine hundred seventy six cases were available for clinical evaluation. Rate of the efficacy of NCS alone and combined with 5-FU was higher (P less than 0.1) in the cases administrated intravenously by drip infusion than in those by one shot injection method, and adverse effects were fewer in the former than in the latter cases. The rate of efficacy of NCS was higher in cases treated with 4,000 mu/day alone intermittently 2-3 times for a week than in those with 2,000 mu/day alone every day. The rate of clinical effect was higher in the cases treated with 4,000 mu of NCS combined with 50 mg of 5-FU intermittently than in those with 2,000 mu of NCS combined with 250 mg of 5-FU every day, especially 20.6% of the former cases given more than 50,000 mu of NCS were interpreted as clinically effective by Karnofsky's criteria of I-A over.

The present study was designed to evaluate the efficacy of chemotherapy by NCS for advanced and/or recurrent carcinoma of the pancreas, mainly nonresectable cases in which exploratory laparotomy or construction of biliary fistula were performed. Three hundred fifty seven cases were available for the study. Of the 357 cases, 116 were treated with NCS alone 5-FU. In the former, the efficacy rate was higher in cases with 2,000 mu/body of NCS every day than in those with 4,000 mu/body of NCS intermittently 2-3 times for a week. 19.6% of the cases treated with more than 40,000 mu of NCS alone in total were interpreted as effective clinically by Karnofsky's criteria of I-A over. In the latter, the efficacy rate was higher in cases with 2,000 mu/body of NCS combined with 250 mg of 5-FU every day than in those with 4,000 mu of NCS combined with 500 mg of 5-FU intermittently, 22.5% of the cases given more than 40,000 mu of NCS in total were interpreted as effective clinically by Karnofsky's criteria of I-A over. The major adverse effects of NCS such as anorexia, vomiting and nausea were observed in 20% of total cases respectively, leucopenia in 10% and fever in 15% of them.
