This report concerns an autopsy case of argyrophilic grain disease (AGD) mimicking temporal Pick's disease. The patient was a Japanese woman without hereditary burden who was 89 years old at the time of death. She developed memory impairment and began wandering at the age of 74, followed by prominent character changes about 6 years after disease onset. A(More)
Osteopontin is a phosphorylated, sialic acid-rich, noncollagenous bone matrix protein containing the Arg-Gly-Asp-Ser amino acid sequence responsible for cell adhesion. The protein strongly binds to hydroxyapatite and play an important role in calcification. Expression of osteopontin mRNA was analyzed in human aortic atherosclerotic lesion by Northern blot(More)
Intracranial cavity volume is used to evaluate brain size relative to the intracranial space. This volume can theoretically be obtained from the weights and densities of the brain and surrounding cerebrospinal fluid (weight method). However, the accuracy of this method has not been examined. In this study, we examined the reliability of the weight method,(More)
We examined brains clinicopathologically from 54 consecutive paroxysmal atrial fibrillation (PAF) patients aged 70 years or older and compared them with those of 59 age-matched controls. Symptomatic cerebral infarctions were present in 29 PAF patients (53.7%) and in 13 controls (22.0%) (p < 0.001). Symptomatic brain infarction was 2.4 times more common in(More)
A monoclonal antibody (Am-3) was produced against senile plaques in the brain of a patient with Alzheimer's disease. Am-3 was reactive with senile plaques of typical, primitive and diffuse type not only in the brain used as immunogen, but also those in the brain of 15 out of 25 autopsy cases of the aged people. Moreover, Am-3 was also reactive with granular(More)
Although CT studies have addressed symptomatic and asymptomatic cerebral infarctions in nonrheumatic atrial fibrillation (NRAF), pathologic verification of the results is lacking. The purpose of this study was to assess the frequency, location, and extent of symptomatic and asymptomatic brain infarction in autopsy specimens from elderly patients with NRAF.(More)
We report an autopsy case of preclinical primary central nervous system (CNS) lymphoma. The case was an 89-year-old female who died of rupture of a thoracic aortic aneurysm. No neurological abnormalities were found throughout our clinical observation. Serum anti-human T-cell leukemia virus type 1 and anti-human immunodeficiency virus were negative. Grossly,(More)
BACKGROUND Although a substantial percentage of patients with rheumatoid arthritis (RA) experience low back pain, the characteristics of lumbar spine pathology in RA patients has been poorly investigated. In our institutions, lumbar spine radiographs indicated scoliosis in 26 patients. The present study aimed to clarify the characteristics of lumbar(More)
BACKGROUND Despite recent advancements in rheumatoid arthritis (RA) pharmacotherapy, surgeons still encounter severely damaged knees. The purpose of the present study was to analyze the mid-term clinical results of total knee arthroplasty (TKA) with metal block augmentation and stem extension. METHODS A total of 26 knees in 21 patients who underwent(More)
Necropsy findings of an acute fatal case of idiopathic interstitial myocarditis were reported. The patient was a 33 year old housewife who had acute cardiac failure on the sixteenth day after the onset of the disease. Necropsy showed important pathological changes confined to the heart. Both ventricles were affected by confluent granulomas with an ill(More)
