Four patients had the clinical features of 'ampulla cardiomyopathy', consisting of acute-onset transient left ventricular apical akinesis with basal normokinesis, normal coronary angiogram, ST-segment elevation and subsequent giant T wave inversion, which mimicked acute coronary syndrome, the onset of which occurred shortly after extreme mental stress.(More)
BACKGROUND Cardiac mortality in Duchenne muscular dystrophy (DMD) has recently become important, because risk of respiratory failure has been reduced due to widespread use of the respirator. The cardiac involvement is characterized by distinctive electrocardiographic abnormalities or dilated cardiomyopathy, but the pathogenesis has remained obscure. In(More)
Canine X-linked muscular dystrophy (CXMD), which was found in a colony of golden retriever, is caused by a mutation in the dystrophin gene and it is a useful model of Duchenne muscular dystrophy (DMD). To investigate the pathogenesis and to develop therapy of DMD, we have established a beagle-based CXMD colony in Japan (CXMDJ) and examined their phenotypes.(More)
Using murine models, we have previously demonstrated that recombinant adeno-associated virus (rAAV)-mediated microdystrophin gene transfer is a promising approach to treatment of Duchenne muscular dystrophy (DMD). To examine further therapeutic effects and the safety issue of rAAV-mediated microdystrophin gene transfer using larger animal models, such as(More)
We review the clinical status of skeletal involvement and cardiac function in three unrelated patients harboring an in-frame deletion of exons 45 to 55 in the DMD gene followed up for 2 to 7 years. Two younger patients diagnosed as having X-linked dilated cardiomyopathy (XLDCM) developed congestive heart failure without overt skeletal myopathy. Heart(More)
BACKGROUND Respiratory support therapy significantly improves life span in patients with Duchenne muscular dystrophy; cardiac-related fatalities, including lethal arrhythmias, then become a crucial issue. It is therefore important to more thoroughly understand cardiac involvement, especially pathology of the conduction system, in the larger Duchenne(More)
We report the pathological and virological findings of the first autopsy case of the 2009 pandemic influenza (A/H1N1pdm) virus infection in Japan. A man aged 33 years with chronic heart failure due to dilated cardiomyopathy, mild diabetes mellitus, atopic dermatitis, bronchial asthma, and obesity died of respiratory failure and multiple organ dysfunction(More)
A 36-year-old Japanese man was hospitalized with coughing and exertional dyspnea (NYHA class I). He was diagnosed as having congestive heart failure, and was treated with diuretics and a beta-adrenergic blocking agent. He responded well to the treatment and his symptoms completely disappeared within a few days. Based on his clinical, laboratory, and(More)
Factor XII Tenri (Y34C), a rare cross-reacting material (CRM)-negative factor XII deficiency, was identified in a 71-yr-old Japanese woman with angina pectoris. In the patient's plasma, factor XII activity and antigen levels were only 1.6% and 5.0%, respectively, of those seen in a normal subject. Immunoblot analysis showed that the secreted factor XII(More)
