Objective. Endoscopy is the gold standard for diagnostic evaluation of upper gastrointestinal symptoms. The relation between endoscopy and use of antisecretory medication on a population level is unknown. The aim of this study was to describe development in the number of patients undergoing first- time endoscopies and their use of antisecretory medication. Material and methods. Data on the use of endoscopies and antisecretory medication (H2 blockers and proton- pump inhibitors) were extracted from five population- based databases and included all citizens in Funen County (population 470,000) who had first time endoscopies between 1993 and 2002. Results. A total of 7,829 first- time endoscopy patients were identified. In 2002 the number of first- time endoscopies as 5.6/1000 persons. The proportion that had redeemed prescription(s) on antisecretory medication the last year before endoscopy increased from 33% (1095/3286) in 1993 to 41% (1012/2445) in 2002 (p = 0.000). Following endoscopy, average use of antisecretory medication increased by 90 defined daily doses (DDD)/patient/year (95% CI 84- 96) in patients with oesophagitis (N = 4850), by 59 DDD/patient/year (95% CI 54- 64) in peptic ulcer patients (N = 4373) and by 18 DDD/patient/year (95% CI 16- 20) in patients with normal endoscopies (N = 16,400). Conclusions. An increasing proportion of patients are treated with antisecretory medication before endoscopy. Following endoscopy, use of antisecretory medication increases irrespective of the diagnostic findings.

Background &Aims: Some patients with early gastroesophageal cancer may appear to “heal" because of antisecretory medication, but the risk of a missed diagnosis is unknown. The aim of the study was to estimate the incidence of gastroesop hageal cancer with or without pre-endoscopic treatment with antisecretory medication. Methods: We extracted data on use of endoscopies, gastroesophageal cancer diagnoses, death, migration, and use of antisecretory medication (H2 blockers and proton pump inhibitors) from 5 population-based registries covering 1974-2002. We included all citizens in Funen County (population, 470,000) who between 1993 and 2002 were investigated by endoscopy for the first time. The patients were followed up until death, emigration, or the end of the study period. Results: Among 27,829 patients with a first endoscopy (mean age, 56 years; 48%male, 115,804 person-years of follow-up), 461 had gastroesophageal cancer diagnosed at the first endoscopy and 52 were diagnosed during a median follow-up of 2.7 years after the first endoscopy. The incidence during follow-up was similar to the background population (standardized incidence ratio, 1.24; 95%confidence interva l, 0.81-1.91), increased with age, and was higher in male patients. The inciden ce of gastroesophageal cancer during follow-up was 46 per 100,000 person-years in users of antisecretory medication the last 180 days before the first endosco py compared with 44 per 100,000 person-years in nonusers (age and sex standardi zed difference, 4 per 100,000 person-years; 95%confidence interval, -14 to 22 ). Conclusions: Very few cancers are missed at endoscopy. The risk seems similar in users and nonusers of antisecretory medication before endoscopy.

达尔文雀是种群进化生态学研究的一个模式类群。然而,关于这些鸟类的寄生虫和疾病方面,我们所知甚少。本文对小地雀( Geospiza fuliginosa)的血液和消化道、中地雀( G. fortis)的消化道寄生虫进行了调查。根据对来自3个岛屿127成体血液样本、22个雏鸟血液和消化道样本的检测,我们没有从小地雀的血液里和中地雀的消化道里发现寄生虫。仅仅从1只来自Floreana岛的小地雀雏鸟的消化道里,发现一种寄生虫(Isosporaspp.) [动物学报51 (3) : 507 -512 , 2005]。

艾德（NRФP）问：由于房子的大小和朝向，我的天线桅杆就设在业余电台旁边那扇窗的外头。我用一根6英尺长的同轴电缆穿过墙给天线馈送，后面接了一根1：1的换衡器馈电450Q窗口线连到43英尺高的桅杆顶端，最后再由它来给134英尺的倒V偶极天线馈送。我之前曾用1：1的空气绕组换衡器连接同轴电缆和平衡线，不过后来在百宝箱里找到了一堆磁环，于是就用它们制作了一个同轴电缆的1：1换衡器，而且因为我不仅想玩160米，还想试试别的波段，所有把23颗全都用上了。这东西的效果似乎和空气绕组换衡器差不多。于是我有个问题。
