Improved detectability of small-bowel lesions via capsule endoscopy with computed virtual chromoendoscopy: A pilot study

Objective. Real-time video capsule endoscopy (CE) with flexible spectral imaging color enhancement (FICE) improves visibility of small-bowel lesions. This article aims to clarify whether CE-FICE also improves detectability of small-bowel lesions. Patients and methods. A total of 55 patients who underwent CE at Hiroshima University Hospital during the period November 2009 through March 2010 were enrolled in the study. Five patients were excluded from the study because residues and transit delays prevented sufficient evaluation. Thus, 50 patients participated. Two experienced endoscopists (each having interpreted more than 50 capsule videos) analyzed the images. One interpreted conventional capsule videos; the other, blinded to interpretation of the conventional images, interpreted CE-FICE images obtained at settings 1-3 (setting 1: red 595 nm, green 540 nm, blue 535 nm; setting 2: red 420 nm, green 520 nm, blue 530 nm; setting 3: red 595 nm, green 570 nm, blue 415 nm). Lesions were classified as angioectasia, erosion, ulceration, or tumor. Detectability was compared between the two modalities. Time taken to interpret the capsule videos was also determined. Results. Seventeen angioectasias were identified by conventional CE; 48 were detected by CE-FICE at setting 1, 45 at setting 2, and 24 at setting 3, with significant differences at settings 1 and 2 (p = 0.0003, p < 0.0001, respectively). Detection of erosion, ulceration, and tumor did not differ statistically between conventional CE and CE-FICE, nor did interpretation time (conventional CE 36 ± 6.9 min; CE-FICE setting 1, 36 ± 6.4 min; setting 2, 38 ± 5.8 min; setting 3, 35 ± 6.7 min). Conclusions. CE-FICE is superior in the lesion detection in comparison with conventional CE and improves detection of angioectasia

Flying disks have many characteristics as a subject in physical education classes. For example, it is easy to control the stamina level, the number of players, and the skill level. The disks have unique flight characteristics. There is extremely little physical contact, so it is not a dangerous sport. It is easy to prepare to play, and the equipment is cheap. The purpose of this study was to clarify the characteristics of students selecting a newsport, and to examine the effectiveness of newsports as a subject in college physical education classes. We conducted a written questionnaire survey of college students. Of them, the number playing newsports was 187, volleyball 179, tennis 85, and baseball 85. The questionnaire included questions on likes and dislikes in PE, likes and dislikes in sport, past sports activity, stamina level, degree of health, the reason for selecting a sport, sports plan, class evaluation, a quantity of exercise. It became clear that the students who selected newsports had the most negative attitude and opinion of exercise and sports. The students who selected tennis showed a similar tendency, differing from the students who selected baseball or volleyball. The students who selected newsports were satisfied with the contents and the exercise quantity of newsports class. They changed their plan for later participation in sports. At the end of newsports class, the number of persons planning to participate in a sport in the future had increased
