TETSU YAMAGUCHI M.D. MASATO NAKAMURA M.D. TAKAHIRO NISHIDA M.D. HISAO HARA M.D. TOSHIYUKI ASAHARA M.D. HIROKO TOHMA M.D. 《Journal of interventional cardiology》1998,11(S5):S114-S119
Cutting balloon (CB) is a unique balloon catheter with 3 or 4 metal blades on its surface making controlled endovascular surgical incisions that show promise of causing less vessel wall injury and less intimai proliferation. Multicenter randomized trials have revealed that CB angioplasty with multiple inflations achieved better lumen enlargement than single inflation and reduced coronary dissection more than plain old balloon angioplasty (POBA). Follow-up results showed CB angioplasty had a smaller late loss and loss index, resulting in lessened restenosis and target lesion revascularization rates. The main indication of CB angioplasty is basically a noncalcified lesion with concentric plaque; however, it could be applied effectively to some lesions unsuitable for POBA including in-stent restenosis, small vessel, long diffuse lesion, or ostial lesion. Additional evaluation would be necessary to determine the role of CB angioplasty in the stent era. 相似文献

We report a case of gastric cancer complicated with very well differentiated adenocarcinoma containing signet ring cells. An endoscopic examination revealed a pedunculated polyp in the fornix of the stomach. A surgical operation was performed and the pathological findings showed very well differentiated adenocarcinoma mimicking gastric foveolae with a poorly differentiated component containing signet ring cells. This is the first case of pedunculated gastric cancer complicated with very well differentiated adenocarcinoma containing signet ring cells and also demonstrating a gastric foveolar phenotype. 相似文献

Abstract Odor perception has been studied in patients with various mental disorders; however, no consensus has been reached as to its detection, identification, or pleasantness/unpleasantness of odors especially in patients with depression. One hundred and nineteen normal elderly individuals living at home were exposed to odors of rose, perfume, white ginger, Indian ink, cigarette smoke, milk, feces and orange scent using the scratch and sniff method. They were asked to rate the strength of each odor, its pleasantness or unpleasantness, their liking for it, and their familiarity with it. They were also asked to complete a self-rating depression scale (SDS). The relationship of the score of each psychological olfactory scale with the SDS score and the difference in the score of each psychological scale between high-SDS and low-SDS groups are discussed. 相似文献

Porcine brain natriuretic peptide (pBNP), purified from porcine brain, had a significant suppressive effect on aldosterone and cortisol secretions in ACTH-treated cultured human adrenal cells. Concomitantly, the intracellular cGMP formation was enhanced by pBNP treatment. A specific pBNP receptor was identified in the human adrenal tissues. Affinity labelling of 125I-pBNP showed two separate molecular weights of specific binding sites for pBNP of 140 and 67 kDa. A 125I-pBNP binding study of the human adrenal membrane fraction demonstrated the presence of high-affinity and low-capacity binding sites for pBNP. Moreover, these binding sites for 125I-pBNP were displaced by unlabelled alpha-rANP as well as pBNP. From these studies, we concluded that pBNP had suppressive effects on human adrenocortical steroidogensis, possibly via a receptor which may be shared with ANP. 相似文献

Abstract: 〈Objective〉 The aim of this study was to assess the accuracy and limitations of endoscopic ultrasonography (US) and dynamic computed tomography (CT) in the preoperative evaluation of esophageal carcinoma. 〈Methods〉 Endoscopic US and dynamic CT were performed preoperatively in 96 patients with an esophageal squamous cell carcinoma. The results were correlated with the histology of specimens resected from patients who had undergone subtotal esophagectomy with lymph node dissection. 〈Results〉 According to the TN staging classification, endoscopic US was superior to dynamic CT for evaluating the depth of tumor infiltration (overall accuracy: EUS 75%, CT 35%) and in assessing regional lymph node metastases (overall accuracy: EUS 77%, CT 67%). However, the T4 stage was not accurately evaluated using endoscopic US in this study. Its specificity was high (97%) but its sensitivity was low (45%). 〈Conclusions〉 We believe endoscopic US is the most accurate method for local tumor staging in esophageal carcinoma. A limitation to endoscopic US staging performed with current instruments was severe stenosis, as it would not permit passage of the instrument (25% of all cases in this study). 相似文献

Parvovirus B19-associated haemophagocytic syndrome with lymphadenopathy resembling histiocytic necrotizing lymphadenitis (Kikuchi's disease) 总被引:3,自引:0,他引:3

A 15-year-old girl developed a haemophagocytic syndrome caused by human parvovirus B19 (PVB19). The cervical lymph node histology, resembling that of histiocytic necrotizing lymphadenitis (HNL, Kikuchi's disease), included several transformed lymphocytes, numerous histiocytes, and massive necrosis. We detected PVB19-positive cells in the lymph node by immunohistochemistry. Possible autoimmune mechanisms in HNL-like diseases triggered by PVB19 are discussed. 相似文献

We studied the sequential changes of plasma levels of immunoreactive '7B2' (IR-7B2), a neuroendocrine polypeptide, after a subcutaneous injection of 50 micrograms of synthetic octapeptide somatostatin analogue (SMS 201-995) in seven patients with acromegaly due to GH-producing pituitary adenoma. Compared to the basal levels, mean plasma IR-7B2 and GH levels significantly decreased, until 5 and 10 h respectively after the administration of SMS 201-995. The mean (+/- SEM) nadir levels of plasma IR-7B2 and GH were 68.1 +/- 10.1 and 13.1 +/- 6.9%, respectively, compared to mean plasma levels before treatment (100%). Plasma IR-7B2 as well as GH levels did not change significantly when saline was administered subcutaneously to three acromegalic patients. In addition, plasma IR-7B2 levels did not change significantly after the administration of SMS 201-995 in normal subjects or in patients with primary hypothyroidism in whom SMS 201-995 induced a decrease of plasma TSH levels. These results strongly suggest that SMS 201-995 has an unequivocal suppressive effect on the synthesis and/or the secretion of 7B2 in human somatotroph adenoma cells. 相似文献

Reliability and validity of the Japanese version of the Zarit Caregiver Burden Interview 总被引:2,自引:1,他引:1
YUMIKO ARAI MD. PhD KEI KUDO MD PhD TORU HOSOKAWA PhD MASAKAZU WASHIO MD PhD HIROKO MIURA PhD SHIGERU HISAMICHI MD PhD 《Psychiatry and clinical neurosciences》1997,51(5):281-287
Abstract Despite a rapid increase in disabled elderly in Japan, the burden of the caregiver has not been properly assessed due to a lack of objective measurements. Our study was aimed at adapting and validating the Zarit Caregiver Burden Interview (ZBI) in Japan, which is one of the most widely used measurements for caregivers' burden in the United States. Sixty-six caregivers answered the self-administered questionnaire, involving the Japanese version of the ZBI and questions regarding their caregiving situation. Our study demonstrated that the Japanese version of the ZBI had equally as high reliability and validity as the original version. The Japanese ZBI had a high test—retest reliability (r = 0.76) and internal consistency (Cronbach's alpha = 0.93). The total score of the ZBI was highly correlated with the caregivers' score of the Center for Epidemiologic Studies Depression Scale (CES-D) score (r = 0.50), as well as a single global rating of burden (r = 0.71). It was also shown that demographic distribution of the score of the Japanese version had a similar trend to that of the original version. Caregivers who looked after patients with behavioral disturbances were found to have a significantly higher ZBI score than those who looked alter patients without behavioral disturbances, which is consistent with previous findings. It is concluded that the Japanese version of the ZBI can be used to measure feelings of burden of caregivers in the Japanese population and can be used for cross-cultural comparison. 相似文献

Abstract A 22 year old woman was incidentally found to have a hepatic small haemangioma-like mass, measuring 1.4 cm in diameter, by an ultrasonographic examination. The mass demonstrated no change in size or appearance for 6 months until the patient began to take oral contraceptives. Eventually, the mass increased to 2.0 cm in diameter after using oral contraceptives for 6 months. A histological examination suggested the mass to be typical focal nodular hyperplasia, and not hepatic adenoma. There was no further change in either size or appearance in the ensuing 1 year after the discontinuation of oral contraceptives. 相似文献
