However, when there are deviations in the intake of these markers by participants in clinical trials it is desirable to improve observations by introducingcorrections, where possible. To date, there is no standard procedure to adjust for such deviations. This report proposes a series of alternatives based on possible scenarios for deviations from the intended intake of radio-opaque markers. The proposed method to correct for missed or delayed consumption of radioopaque markers can help to increase the accuracy of the CTT measurements in clinical trials.展开更多

METHODS Over a 6-mo period, consecutive in patients with mental illness were recruited from the Somang Hospital Psychiatry Unit. A combined exercise program that included 60 min per day of exercise 3 d per week for 12 wk was performed. Physical fitness and CTT of the patients were measured twice before and twice after the exercise program. CTT was measured using a multiple marker technique with a radio-opaque marker. Changes in the exercising patients' CTT and weight-,cardiovascular-and fitness-related parameters were statistically assessed.RESULTS After the 12-wk combined exercise intervention, decreased intestinal transit time was observed in all CTTs of the exercise group, including the right CTT(exercise: 15.6 ± 15.2 vs 9.2 ± 11.9, control: 13.1 ± 10.4 vs 10.9 ± 18.7), left CTT(exercise: 19.7 ± 23.5 vs 10.4 ± 13.2, control: 19.2 ± 19.0 vs 16.9 ± 19.8), recto-sigmoid CTT(exercise: 14.3 ± 16.7 vs 6.7 ± 7.9, control: 15.0 ± 14.4 vs 19.3 ± 30.3), and total colonic transit time(TCTT)(exercise: 50.2 ± 38.1 vs 27.1 ± 28.0, control: 47.4 ± 34.6 vs 47.3 ± 47.3). After the 12-wk combined exercise period, TCTT was significantly shortened in the exercise group compared with that in the control group. In addition to eating habits, water intake, and fiber intake, the increased physical activity level as a result of the 12-wk combined exercise program reduced the CTT.展开更多

Commonly metallic sharp objects, bullets, sharpnels, glass particles, hard wooden pieces are the causes of penetrating injury to bones. Radio-opaque objects are easy to detect and thus retrieval is relatively simpler than the radiolucent objects. Non-biological foreign bodies do not incite any reaction in the host bone whereas biological foreign bodies of either plant or animal origin cause hypersensitivity reaction. Osteitis along with excessive formation of new bones may be presented as a part of host reaction to the foreign body. We are presenting here an interesting case of a fisherman boy who sustained penetrating injury to radius by fish bone resulting in osteitis and a chronic non-healing sinus with watery discharge.展开更多
