Monophasic action potentials, recorded with contact non-suction electrodes, have been used both clinically and experimentally. However, to date no systematic microelectrode validation studies have been done to underlying myocardial cell populations from different myocardial regions with different transmembrane potential profiles. In the present study(More)
BACKGROUND The extent of clinical exposure needed to ensure quality care has not been well determined during internal medicine training. We aimed to determine the association between clinical exposure (number of cases seen), self- reports of clinical competence, and type of institution (predictor variables) and quality of care (outcome variable) as measured(More)
BACKGROUND As with other types of dementia, the behavioral and psychological symptoms of dementia (BPSD) can make caregiving difficult for patients with dementia with Lewy bodies (DLB). We hypothesized that administration of donepezil at an increased dose of 10 mg/day might dose-dependently improve BPSD in DLB patients with relapse, after their symptoms had(More)
A n 11-year-old boy presented with giant calcifications on the chest radiograph, detected during screening for heart disease (Figure). He had been diagnosed with measles twice, at 1 and 2 years of age. Before this screening, he had been asymptomatic. An ECG revealed sinus rhythm and no specific ST-T–wave changes. The CT scan showed 2 giant circular masses(More)
We distributed a questionnaire to highlight the effects of post transfusion graft-versus-host disease (PT-GVHD) and to elucidate the risk factors that would predispose people to the disease. The questionnaire described the pathogenesis and the clinical profiles of PT-GVHD and was distributed to doctors in Japan whose hospital conducted more than 1000 units(More)
