| 1 | Small bowel tumors detected and missed during capsule endoscopy: Single center experience显示文摘AIM:To characterize small bowel(SB)tumors detected by capsule endoscopy(CE),and identify missed tumors.METHODS:The study included 145 consecutive patients in whom 150 CEs were performed.Following CE,the medical records of the study population were reviewed.Results of double-or single-balloon enteroscopy performed after CE and the results of surgery in all patients operated on were retrieved.The patients were contacted through telephone interviews or postal mail.In addition,the national cancer registry and the polish clinical gastrointestinal stromal tumor(GIST)Registry were searched to identify missed neoplasms.RESULTS:Indications for CE included overt and occult obscure gastrointestinal bleeding(n=81,53.7%),anemia(n=19,12.7%),malabsorption(n=18,12%),abnormal CB follow through(n=9,6%),abdominal pain(n=7,5%),celiac disease(n=5,3%),neuroendocrine tumor(n=3,2%),Crohn’s disease(n=2,<2%),Peutz-Jeghers syndrome(n=2,<2%),other polyposes(n=2,<2%),and diarrhea(n=2,<2%).The capsule reached the colon in 115(76.6%)examinations.In 150 investigations,CE identified 15SB tumors(10%),14 of which were operated on or treated endoscopically.Malignancies included metastatic melanoma(n=1),adenocarcinoma(n=2),and GIST(n=3).Benign neoplasms included dysplastic Peutz-Jeghers polyps(n=4).Non-neoplastic masses included venous malformation(n=1),inflammatory tumors(n=2),and a mass of unknown histology(n=1).During the follow-up period,three additional SB tumors were found(2 GISTs and one mesenteric tumor of undefined nature).The National Cancer Registry and Polish Clinical GIST Registry revealed no additional SB neoplasms in the post-examination period(follow-up:range 4.2-102.5 mo,median 39 mo).The sensitivity of CE for tumor detection was 83.3%,and the negative predictive value was 97.6%.The specificity and positive predictive value were both 100%.CONCLUSION:Neoplasms may be missed by CE,especially in the proximal SB.In overt obscure gastrointestinal bleeding,complementary endoscopic and/or radiologic diagnostic tests are indicated. | Edyta S Zagorowicz Anna M Pietrzak Ewa Wronska Jacek Pachlewski Piotr Rutkowski Ewa Kraszewska Jaroslaw Regula | 2013 | World Journal of Gastroenterology2013，19，47： | 10 |
| 2 | 粮食生产中的养分管理:实现农业经济与环境目标显示文摘在过去一个世纪中,管理的概念已经发生了很大变化。今天,管理已经被认为是'实现目标的专门活动'。管理技术是决定农业生态系统经济和环境行为的一个最重要的因素。养分管理是'为实现农业经济和环境目标的养分管理,'它需要对养分循环、小区和农场特定的指导方针和技术,通常是直接指导的准确认识。特别是在包括农作物和家畜的复合农场系统,这些活动是多样化而复杂的。为了达到有效性,经济和环境目标必须是连贯的、灵活的和可操作的。同样,在策略、战术和实践层面上,它们也必须是被详细阐明和可以定量完成。本文应用来自波兰和荷兰的农场数据资料,展示反映了两国政府提供政策和措施所产生的经济激励作用会怎样通过集约化管理的复合农场系统两个因素中的其一改善养分利用的效率。 | Oene Oenema Stefan Pietrzak 崔小琳 | 2002 | AMBIO-人类环境杂志2002，31，2： | 4 |
