The report concerns a 21-year-old woman who, after having taken oral contraceptives for three months, developed the Budd-Chiari syndrome as the results of a widespread chronic obliterative process involving the intrahepatic venous system. The diagnosis was established by liver biopsy. She was treated with supportive measures and completely recovered after(More)
BACKGROUND In the general population, the incidence of bundle branch block (BBB) is relatively low, and its effects on long-term prognosis have not been established. Previous studies on the incidence and correlation of BBB to clinical factors have produced conflicting results. However, the incidence of BBB was strongly related to age. This study aimed to(More)
BACKGROUND AND OBJECTIVES The purposes of this study are 1) to investigate the relationship between resting baseline Pd/Pa, determined by the ratio of the pressures proximal (Pa) and distal (Pd) to the target lesion before, inducing hyperemia and fractional flow reserve (FFR) and 2) to identify a resting baseline Pd/Pa range that might reliably preclude the(More)
Total creatine activity was greatly increased, and creatine kinase MB isoenzyme was measurable in the serum of a patient with dermatomyositis. In contrast, total CK activity in an extract of skeletal muscle from this patient was markedly decreased as compared with normal muscle extracts, but contained about the normal proportion of the MB isoenzymes, 1.5%.(More)
A 41-year-old man was admitted to the emergency department for sudden-onset right hemiparesis. He had no history of diabetes mellitus, hypertension, arrhythmias, or stroke. However, he had a 20-year history of smoking, dyslipidemias, and hypothyroidism (laboratory test on admission revealed elevated thyrotropin [13.16 IU/mL; reference, 0.27 to 4.2], normal(More)
A25-year-old male was admitted to the emergency department for severe dyspnea (New York Heart Association Class IV). Physical examination revealed a short stature (139.5 cm), enlarged head, prominent supraorbital ridge, wide nasal bridge, flattened midface, thickened lips, macroglossia, short neck, claw hands, and umbilical hernia. The patient's(More)
BACKGROUND Various studies have reported that the administration of adenosine (ADO) in cardioplegia reduces myocardial ischemic injury, but this timing may not utilize ADO's potential against myocardial reperfusion injury. This study tested the hypothesis that ADO-supplemented blood cardioplegia (BCP) or ADO administered during reperfusion reduces(More)
A 37-year-old man was found to have classic malacoplakia of the rectum after three courses of chemotherapy for stage IV Hodgkin's disease. Sigmoidoscopy with excisional biopsy was performed because of rectal bleeding. The biopsy specimen of the rectal lesion showed focal extensive granulomatous changes with large macrophages containing round, dense(More)
To improve the operation lifetime of organic solar cell, two different diphenylacetylene polymers were tested as UV blocking layer. One of them showed either stronger UV absorption or a relatively intense fluorescence emission in the visible region which is well overlapped with the absorption of P3HT in the OSC. The diphenylacetylene polymer film(More)
A case of pulmonary dirofilariasis in a 69-year-old woman is presented. A review of the literature revealed 56 documented cases. As in most cases of pulmonary dirofilariasis, our patient presented roentgenologically a single noncalcified coin lesion and required thoracotomy for diagnosis. The gross and histologic characteristics of the lesion, the life(More)
