Over a period of 54 months, every patient undergoing colon surgery at the Hadassah University Hospital in Jerusalem was followed up prospectively by the same nurse epidemiologist. A total of 403 patients completed the analysis. Risk factors for postoperative wound infection were explored in an epidemiological study, using both single and multivariate analysis. ⋯ In patients undergoing more than one operation, the risk for infection was greater if the second operation followed a surgical complication than if it was performed as an elective second procedure; whether the first operation was elective or not did not affect the infection rate. Second operations performed within 7 days of the first carried a higher risk for infection than those performed later. The different prophylactic protocols used during the period of investigation did not have an independently significant contribution to the risk of infection.

Case Reports
Total aortic replacement for chronic aortic dissection occurring in patients with and without Marfan's syndrome.
Total aortic replacement including aortic valve was performed successfully in the two patients in whom this method of treatment was utilized to correct a chronic dissecting aortic aneurysm. Both patients had moderately severe aortic insufficiency producing increasing heart strain and progressive enlargement of the false lumen of aortic dissection involving the entire aorta despite ideal blood pressure control. In addition, one patient had Marfan's syndrome. ⋯ Left vocal cord paralysis occurred in both patients and transient mild paraparesis occurred in only one. Both patients are alive and well, one at 13 months and one at 6 weeks. This experience suggests an additional treatment modality for selected patients with complications of chronic aortic dissection.
