Systolic anterior motion (SAM) of the anterior mitral leaflet with mitral-septal contact was generally thought to be a major contributor to dynamic left ventricular outflow tract obstruction in patients with hypertrophic cardiomyopathy. We report an interesting case of SAM of the posterior mitral leaflet in a patient without left ventricular hypertrophy,(More)
Presbycusis is the progressive hearing loss caused by histologic changes due to aging. Schuknecht described four histopathologic types of presbycusis and correlated these findings to audiometric data. In a retrospective study, some strict criteria were set to distinguish the "pure" cases of presbycusis in a group of 1,181 subjects, 50 years of age and(More)
Recent advances in interventional devices and technology have greatly improved the results of percutaneous transluminal angioplasty (PTA), and it is now being widely used. However, it is important to obtain information regarding its results and its long-term patency. We examined the primary success rates and long-term patency in 29 limbs out of 27 patients(More)
Congestive heart failure developed in a 42-year-old man who had very mild acromegalic features. Echocardiography showed a marked dilatation of the left ventricle and decreased systolic function. Laboratory examinations revealed the elevated levels of growth hormone and insulin-like growth factor-1 and pituitary microadenoma was demonstrated by magnetic(More)
A 73-year-old Japanese woman was admitted to the intensive care unit of our hospital with the diagnosis of eosino-philic pneumonia and congestive heart failure. Laboratory examination revealed a white blood cell count of 8100/mm 3 with 49% eosinophils, 1568 IU/mL IgE, 467 IU/L lactate dehydrogenase with 40% lactate dehydrogenase-1, a brain natriuretic(More)
