SUMMARY A greater emphasis on day case surgery within the health service is seen as a method of improving efficiency and reducing expenditure. We interviewed 90 consecutive patients undergoing nasal surgery who had been preoperatively assessed as being fit for day case surgery. They were randomised into three groups regarding the duration of postoperative nasal packing. All patients stayed overnight following surgery and were interviewed prior to discharge. Some 52% of the overall sample would be happy to have nasal surgery performed as a day case. If the nasal pack was removed after two hours, this figure rose to 67%. This difference in patient acceptance did not attain statistical significance overall, but there was a significant difference in those undergoing submucosal resection. There was no difference in the age, sex distribution or type of surgery performed between each group. The audit commission quotes patient satisfaction with day case surgery at 80%. Nasal surgery was not examined in their report, but was included as one of a set of procedures suitable for consideration. Although day case nasal surgery may be safe, further research regarding patient acceptance is required. 相似文献

A case report of a boy who demonstrates features of an athlete's heart, associated with dilatation of the coronary artery, is presented. The importance of distinguishing this benign condition from pathologic causes such as cardiomyopathy, and risk of sudden death in these athletes is discussed. 相似文献

Cushing’s syndrome (CS) is common after oral steroid use and has also been reported following topical or inhaled use, but it is extremely uncommon after intranasal administration. In this paper, we present the case of a child who developed CS after intranasal application of combined moxifloxacin-dexamethasone eye drops for epistaxis for a period of 3 months. CS caused by ocular preparations of steroids has not been reported previously. This case report highlights the fact that even eye drops can contain high doses of steroids and can lead to CS especially in children and especially if used intranasally. Ocular steroid drops should not be used intranasally. To minimize gastrointestinal absorption and therefore the risk of CS, nasal sprays should be preferred over nasal drops for intranasal steroid application.Key words: Cushing’s syndrome, eye drops, dexamethasone, epistaxisConflict of interest:None declared. 相似文献

Jejunal access loop is fashioned in patients who undergo Roux en Y hepaticojejunostomy and biliary intervention is anticipated on follow up. Post-operative study of the biliary tree through the access loop is usually done under fluoroscopic guidance. We present a series of 20 access loop cholangiograms performed in our institution between August 2004 and November 2008. We aimed to evaluate the safety and efficacy of the procedure and to highlight the role of CT guidance in procuring access. Access loop was accessed using CT (n = 13), ultrasound (n = 3) or fluoroscopic guidance (n = 4). Fluoroscopy was used for performing cholangiograms and interventions. Twelve studies had balloon plasty of the stricture at anastomotic site or high up in the hepatic ducts. Seven studies showed normal cholangiogram. Plasty was unsuccessful in one study. Technical success in accessing the jejunal access loop was 100%; in cannulation of anastomotic site and balloon plasty it was 95%. One case required two attempts. Procedure-related complications were not seen. All patients who underwent balloon plasty of the stricture were doing well for variable lengths of time. Access loop cholangiogram and interventions are safe and effective. CT guidance in locating/procuring the access loop is a good technique. 相似文献

人参质量的化学模糊模式识别 总被引:17,自引:0,他引:17
模拟中医用药习惯制备25个生态环境和生长年数不同的人参样品的水、酒提取液,用紫外—可见分光光度法、高效液相色谱法和电感偶合等离子体发射光谱法获取反映提取液内化学成分整体的数据。再用抗疲劳作用、抗利尿作用和巨噬细胞吞噬功能测定提取液的生物活性。然后以药理实验的结果为依据对上述化学数据进行特征抽取,求解模糊关系方程,以探明人参疗效权重不同的有效成分和它们的配伍关系。最后通过成分的相关分析,制定出一个评价人参质量的新方案。所提出的方法学对中药质量的评价和中药有效成分的确定具有普遍意义。 相似文献
