The purpose of this study was to determine if a 1-minute scrub with povidone-iodine followed by alcohol foam is as effective as a 5-minute scrub with povidone-iodine in reducing skin bacterial counts. A 1-minute scrub with povidone-iodine followed by alcohol foam and a 5-minute scrub with povidone-iodine was done. In the first study, cultures were obtained after 1 hour, and in the second study, cultures were obtained after 2 hours. Cultures were obtained by imprinting the first, second, and third fingers on nutrient agar plates. Bacterial counts were then obtained at 24 and 48 hours. The study involved two groups of 12 participants and a total of 37 patients over a period of 5 months. The results show that there was no significant difference between the number of colonies cultured for the 1-minute scrub compared with the 5-minute scrub for either the 1-hour or the 2-hour study. In fact, the total number of bacterial colonies was less after the 1-minute scrub with alcohol foam than after the standard 5-minute scrub in both the 1-hour group (10 vs. 18) and the 2-hour group (18 vs. 44).
From 1976 to 1993 we inserted 160 chronic peritoneal dialysis catheters for renal failure patients. Three of these patients developed sudden onset of penile and scrotal edema after the catheter had been in place for several months. The first patient was diagnosed by instilling technetium sulfur colloid in the peritoneal cavity, which showed the radioisotope flowing via the right inguinal canal. He was operated on and the processus vaginalis was tied off and the scrotal and penile edema resolved. Subsequently, two more patients were seen with similar problems and had their inguinal canals explored and the processus vaginalis in one and the hernia sac in the other were found and tied off, which resulted in resolution of the problem. This is an uncommon complication, reported to occur in 3 to 4% of patients.
Pulmonary emboli are a source of significant morbidity and mortality in the trauma population. The incidence at Robert Packer Hospital is 0.23% with a mortality rate of 50%. A retrospective analysis over the last six years found eight out of 3450 trauma patients with documented pulmonary emboli. The purpose of this study was to identify those risk factors associated with the development of pulmonary embolism in trauma patients.
Carotid artery aneurysms are rare. Three cases of carotid artery aneurysms, one false, one ruptured, and one nonruptured are presented. All were treated successfully without complications. Relevant literature regarding pathophysiology, differential diagnosis, and options in surgical treatment is reviewed.at UQ Library on June 13, 2015 ves.sagepub.com Downloaded from
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
