In this prospective, multinational cohort of patients with S. aureus PVIE, EVS was not associated with reduced 1-year mortality. The decision to pursue EVS should be individualized for each patient, based upon infection-specific characteristics rather than solely upon the microbiology of the infection causing PVIE.
Mucormycosis is on the rise especially among patients with immunosuppressive conditions. There seems to be more cases seen at the end of summer and towards early autumn. Several studies have attempted to look at the seasonal variations of fungal pathogens in variou indoor and outdoor settings. Only two reports, both from the Middle East, have addressed the relationship of mucormycosis in human disease with climate conditions. In this paper we review, the relationship of indoor and outdoor fungal particulates to the weather conditions and the reported seasonal variation of human cases.
Clostridium difficile colitis infection is on the rise and is considerably increasing the duration of hospital stay, as well as healthcare costs. The management of C. difficile colitis has become more challenging with the increasing failure of therapeutic response to metronidazole and oral vancomycin. Tigecycline is a new glycylcycline that has shown in vitro activity against C. difficile. We report herein a case of C. difficile colitis that failed to improve on a combination of metronidazole and oral vancomycin. The patient subsequently developed a surgical abdomen secondary to refractory C. difficile colitis, but was successfully treated with a combination of rifaximin and tigecycline after she refused to undergo surgical treatment.
The objective of this study was to examine the epidemiology and the clinical manifestations of typhoid fever as well as the susceptibility and strain relatedness of Salmonella typhi isolates in Lebanon from 2006 to 2007. A total of 120 patients with typhoid fever were initially identified from various areas of the country based on positive culture results for S. typhi from blood, urine, stools, bone marrow and/or positive serology. Clinical, microbiological and molecular analysis was performed on cases with complete data available. These results indicated that drinking water was an unlikely mode of transmission of the infection. Despite increasing reports of antimicrobial resistance among S. typhi isolates, the vast majority of these isolates were susceptible to various antibiotic agents, including ampicillin, cephalosporins, quinolones, and trimethoprim/sulfamethoxazole. Molecular analysis of the isolates revealed a predominance of one single genotype with no variation in distribution across the geographical regions.
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.
