To identify risk factors for sporadic Salmonella Typhimurium definitive phage-type 104 (DT104) and non-DT104 diarrhoeal illness in Canada, we conducted a matched case-control study between 1999 and 2000. Cases were matched 1:1 on age and province of residence. Multivariate analysis suggested that recent antibiotic use [odds ratio (OR) 5.2, 95% confidence interval (CI) 1.8-15.3], living on a livestock farm (OR 4.9, 95% CI 1.9-18.9), and recent travel outside Canada (OR 4.1, 95% CI 1.2-13.8) are independent risk factors for DT104 illness. Similar analyses suggested that recent travel outside North America is a sizable risk factor for non-DT104 illness (OR 66.8, 95% CI 6.7-665.3). No food exposure was a risk factor in either analysis. Educating health-care providers and the public about appropriate antibiotic use and antimicrobial resistance is important. Appropriate administration of antibiotics to livestock, particularly cattle, and hygienic measures such as handwashing after contact with farm animals may reduce risk. Travel represents an important and probably underestimated risk factor for sporadic illness with S. Typhimurium. Improved national surveillance and detailed investigation of travel-related illness are required.

Despite the growth of the elderly population, most surgical training programs lack formalized geriatric education. The authors' aim was to implement a formalized geriatric surgery curriculum at an academic medical center. Surgery residents were surveyed on attitudes toward the care of elderly patients and the importance of various geriatric topics to daily practice. A curriculum consisting of 16 didactic sessions was created with faculty experts moderating. After curriculum completion, residents were surveyed to assess curriculum impact. Residents expressed increased comfort in accessing community resources. A greater percentage of residents recognized the significance of delirium and acute renal failure in elderly patients. Implementing a geriatric surgery curriculum geared toward surgery residents is feasible and can increase resident comfort with multidisciplinary care and recognition of clinical conditions pertinent to elderly surgical patients. This initiative also provided valuable experience for geriatric surgery curriculum development.
