In Kobe University Hospital, a new method for endoscopic mucosal resection (EMR) using insulated‐tip electrosurgical knife (IT‐EMR) for early gastric cancer (EGC) was introduced from November 2001. To achieve an effective and safe IT‐EMR procedure, we use a high‐frequency surgical unit for cutting and coagulation (ERBOTOM ICC 200) with automatically controlled cutting mode (ENDOCUT). In this study, we show not only our results of IT‐EMR for EGC in comparison with those of the conventional strip biopsy method, but also the optimal conditions for the apparatus of a high‐frequency surgical unit to prevent complications such as bleeding and perforation. 相似文献

Reliability and validity of the Japanese version of the Yale-Brown Obsessive-Compulsive Scale 总被引:3,自引:2,他引:1
TERUO NAKAJIMA MD MICHIHIKO NAKAMURA MD CHIAKI TAGA MD SAKAE YAMAGAMI MD NOBUO KIRIIKE MD TOSHIHIKO NAGATA MD MASAMI SAITOH MD TOSHIHIKO KINOSHITA MD YOSHIYASU OKAJIMA MD MASANORI HANADA MD HIROYASU TAZOE MD KENYA YAMAGUCHI MD 《Psychiatry and clinical neurosciences》1995,49(2):121-126
Abstract The reliability and validity of the Japanese version of the Yale-Brown Obsessive-Compulsive Scale (JY-BOCS) were determined by 20 raters for 12 Japanese patients with obsessive compulsive disorder at four institutions. Interrater reliability for the total JY-BOCS score was excellent, and the intraclass correlation coefficient was high (ICC = 0.960). Internal consistency was also excellent (Cronbach's α= 0.889). Concurrent and discriminant validity of the JY-BOCS was examined by comparing the scores on the JY-BOCS with those on the Maudsley Obsessional Compulsive Inventory (MOCI) and scales for depression and anxiety. A slight correlation was found between scores on the JY-BOCS and MOCI, but no significant correlations were found between scores on the JY-BOCS and those on scales for depression or anxiety. 相似文献

Abstract Thirty-nine patients with schizophrenia, diagnosed according to DSM-III-R, who were under 15 years of age, were studied in two groups; 16 subjects with obsessive-compulsive symptoms during the prodromal phase, and 23 with no obsessive-compulsive disorders. The group with obsessive-compulsive symptoms during the prodromal phase was characterized by a higher ratio of males, higher incidences of perinatal and brain computed tomography (CT) abnormalities, fewer hereditary factors, longer duration of the prodromal phase, and a higher incidence of insidious onset and negative symptoms compared with the group without such prodromal symptoms. Schizophrenic patients with obsessive-compulsive symptoms during the prodromal phase were clinically distinct from those without, which suggests the possibility of subtype categorization. 相似文献

AIM: To evaluate the incidence, nature and prognosis of multiple primary malignancies involving renal cell carcinoma (RCC) in Japan. METHODS: Between 1975 and 1998, 319 patients underwent an operation for RCC at Hokkaido University, Sapporo, Japan. The incidence of other primary malignancies was determined and classified as antecedent, synchronous or subsequent. Follow-up was obtained by thorough chart review or telephone interview, and ranged from 0 to 276 months (median 49.0 months). To analyze the influence of other primary malignancies on prognosis, overall and cause-specific survival rates of the patients with an antecedent or synchronous malignancy were compared to the remaining patients. RESULTS: Of the 319 patients there was at least one other malignancy in 38 patients (12%). Four patients had two other malignancies. The other malignancies were antecedent in 13, synchronous in 19 and subsequent in 10 patients. Twenty-two patients had gastrointestinal cancer. In cases of antecedent or synchronous diagnosis of other primary malignancies, RCC was commonly incidental, small or low-stage. Multivariate analysis using Cox's proportional hazards model showed that, for overall survival, the presence of other antecedent or synchronous malignancies was the second most significant prognostic factor, following the pathological stage of RCC. CONCLUSIONS: In Japanese patients with RCC, the incidence of other primary malignancies was not uncommon and these malignancies contributed to the prognosis of these patients. Therefore, the malignant potential of individual tumors should be paid careful attention in the management of these patients. 相似文献

Transesophageal echocardiography was conducted to determine the systolic pattern of the anterior mitral leaflet in patients with flat chest, and to differentiate it from that associated with mitral valve prolapse. The fronto-sagittal index (an index of chest flattening) was determined in 50 subjects using chest radiographs, and was used to classify them into a flat chest group (index < 0.38, n = 28) and a normal chest group (index ≥ 0.38, n = 22). We then used transesophageal echocardiography to examine the anterior leaflet in these subjects. A significant positive correlation was observed between the fronto-sagittal index and the short-to long-axis diameter ratio of the left ventricle in all patients. These parameters, and the left atrial dimension were lower in the flat than the normal chest group. The clear zone area of the anterior leaflet during mid-to late-systole was significantly larger in the flat chest group. However, no intergroup differences existed in the rough zone area of the anterior leaflet or in the middle scallop area of the posterior leaflet. Mitral regurgitation was observed in 20 and 12 subjects in the flat and normal chest groups, respectively. The maximum mitral regurgitant area did not differ between the two groups. The clear zone area of the anterior leaflet increased significantly following inhalation of amyl nitrite in 22 subjects of both groups, but the other areas did not increase. The mitral regurgitant area decreased or disappeared after amyl nitrite at a similar rate in each group. Thus, the decrease in the antero-posterior dimension of the thorax in subjects with flat chest affects the systolic pattern of the clear zone of the anterior leaflet more than that of the rough zone of the anterior leaflet or the posterior leaflet. This systolic pattern in such patients differs from that associated with mitral valve prolapse. 相似文献

A total of 108 samples of sputum obtained from twenty patients with bronchial asthma were examined for appearance of basophils and eosinophils. Both cell types are present in sputum during an asthmatic attack and disappear at the conclusion of the attack. Their presence correlates with the severity of the disease. It has previously been demonstrated that the blood basophils count falls during attacks of bronchial asthma, and the present study suggests that basophils move from the blood stream into bronchial tissue during the acute phase of an asthmatic attack. 相似文献

The metabolic behavior, clearance, and pulmonary effects ofgadolinium (Gd), one of the rare earth elements, were investigatedafter single intratracheal instillation of gadolinium chloride(GdCl3) in male Wistar rats. There was a dose-related increasein Gd content of lung tissue. Gd content in the supernatantof bronchoalveolar lavage fluid (BALF) did not exceed 5 µgGd/ BALF even at a dose of 100 µg Gd/rat. Gd in the lungtissue decreased very slowly with a biological half-life of136 days at a dose of 50 µg Gd/rat. On the other hand,Gd content in the super natant of BALF was not detectable after31 days. These results suggest that intratracheally instilledGd can be retained in epithelial lining fluid only to a limitedextent as soluble forms and is deposited in the lung tissueprobably in insoluble forms which are metabolized very slowly.Calcium (Ca) content in BALF increased more rapidly than othertoxicological indices such as lactate dehydrogenase activity,protein concentration, and inflammatory cell counts. In thelung tissue, levels of Ca in Gd-instilled groups did not differfrom the control value. Although these data suggest that theorigin of Ca may be blood plasma, biological and/or toxicologicalsignificance of increased Ca is not known. The number of neutrophilsreached the maximum at 12 hr after instillation, indicatingthat Gd has the potency to cause acute lung toxicity. Summarizingthe observation, Gd instilled intratracheally into rats wasdeposited in the lung tissue in nonsoluble forms with an extremelylong half-life, while the metal caused a rapid and selectiveinfiltration of serum Ca before acute lung toxicity. 相似文献

Keratinocyte growth factor is an endogenous stimulant of rabbit gastric epithelial cell proliferation and migration in primary culture 总被引:2,自引:0,他引:2
MORIO TAKAHASHI SHINICHI OTA SHUJI NISHIMURA KEIJI OGURA SHIN MAEDA NOBUO TODA EIJI HAMADA AKIRA TERANO MASAO OMATA 《Journal of gastroenterology and hepatology》1996,11(11):1089-1096
Mesenchymal-epithelial interactions are important in the gastric mucosal repair. However, specific factors responsible for such interactions have not been established. In the present study, keratinocyte growth factor (KGF) significantly stimulated proliferation of gastric epithelial cells dose dependently and synergistically with hepatocyte growth factor (HGF), epidermal growth factor (EGF) and insulin. Restitution of gastric epithelial monolayers was also assessed, using a round wound restitution model. Keratinocyte growth factor facilitated the restitution of gastric epithelial cells significantly but did not have any effects on gastric fibroblasts. Keratinocyte growth factor receptor mRNA was expressed by gastric epithelial cells, indicating that these effects were elicited by the specific receptor mediated pathway. Northern blot analysis revealed the expression of KGF mRNA in gastric fibroblasts but not in gastric epithelial cells, indicating the production of KGF. These results suggest that KGF might be involved in gastric mucosal repair, through mesenchymal-epithelial interaction. 相似文献

Cervical spinal neurinomas are benign tumors that arise from nerve roots. Based on their location, these tumors can also take the form of a dumbbell-shaped mass. Treatment strategies for these tumors have raised several controversial issues such as appropriate surgical indications and selection of surgical approaches for cervical dumbbell-shaped spinal neurinomas. In this report, we review previous literature and retrospectively analyze cervical spinal neurinoma cases that have been treated at our hospital. Surgical indications and approaches based on tumor location and severity are discussed in detail. Thus, with advances in neuroimaging and neurophysiological monitoring, we conclude that appropriate surgical approaches and intraoperative surgical manipulations should be chosen on a case-by-case basis. 相似文献

Transurethral resection is usually performed using an all-in-one drape with a fluid collection pouch, drainage port and hose. Gravity drainage of irrigation fluid through the hose is often hampered, resulting in fluid retention in the pouch. We applied a siphon principle to facilitate fluid drainage by making a U-shaped bend near the distal end of the hose, using an adhesive tape, and hooking the distal end of inverted U shape on the edge of bucket placed on the floor. When the hose is filled with irrigation fluid up to the crest of the siphon, fluid flow driven by atmospheric pressure continues until the pouch is evacuated. Repriming and restarting occur automatically throughout the operation. This simple device has virtually eliminated fluid retention in the pouch and proved to be especially useful in transurethral prostatectomy, which requires a large amount of irrigation fluid. 相似文献
