BACKGROUND The cephalosporin class has been associated with an increased risk of bleeding among elderly patients receiving warfarin. Urinary tract infections (UTI) are the most prevalent infection in elderly patients. OBJECTIVE To determine the extent of interaction between antibiotics used in the treatment of UTI, particularly specific cephalosporins and warfarin. METHODS A retrospective c...
The available randomized controlled trial evidence suggests that third generation cephalosporins are as effective as standard treatment regimens that include chloramphenicol for the treatment of bacterial meningitis. Once or twice daily dosing schedules with ceftriaxone are more convenient than the four times daily schedules required for chloramphenicol and ampicillin regimens. There is also so...
This retrospective study was conducted in order to determine the clinical and microbiologic features of infection with Salmonella enterica serotype Choleraesuis. Between March 1999 and December 2002, 55 patients with 66 isolates were enrolled for analysis. The ratio of males to females was 2.2:1. Most patients were older than 60 years (56%) and had underlying diseases (78%), such as diabetes me...
OBJECTIVES Making valid comparisons of antimicrobial utilization between hospitals requires risk adjustment for each hospital's case mix. Data on individual patients may be unavailable or difficult to process. Therefore, risk adjustment for antimicrobial usage frequently needs to be based on a hospital's services. This study evaluated such a strategy for hospital antimicrobial utilization. ME...
INTRODUCTION The aim of this study was to determine the prevalence of intestinal carriage of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae and carbapenem-resistant Gram-negative bacilli in the community in Buenos Aires, Argentina. METHODOLOGY Faecal samples from 164 non-hospitalized patients were cultured on CHROMagar KPC and CHROMagar ESBL plates. Isolates resistant to...
This study was conducted to find the etiology of acute diarrhea in Iranian children and determine the antimicrobial resistance patterns. The pathogenic bacteria were recovered from 110/269 (40.9%) diarrheal fecal samples with the following profiles: the most predominant pathogen was diarrheagenic Escherichia coli (DEC) (43.6%), comprising enteroaggregative E. coli (23.6%), enteropathogenic E. c...
INTRODUCTION Wound infections remain a public health problem, despite the progress made on improving surgical techniques and antibiotic prophylaxis application. Misuse of antibiotics to prevent bacterial infections leads to increased bacterial resistance and their dissemination. MATERIAL AND METHODS The study refers to 470 samples taken from wound infections of which only multi-drug resistant...
Twenty-seven adult patients were identified as having community-acquired Klebsiella pneumoniae meningitis. The K. pneumoniae isolates, collected from cerebrospinal fluid samples, were tested for in vitro antimicrobial susceptibilities. The prognostic factors of these 27 patients were also analysed. All of the third- and fourth-generation cephalosporins tested, as well as monobactam, carbapenem ...
Background: β-lactamase mediated resistance is the most common mechanism which renders the β-lactam antibiotics ineffective against bacteria including Escherichia coli. The development of resistance has led to the widespread empirical use of higher generation cephalosporins and it is likely that the third generation cephalosporins are also losing their efficacy by the same mechanism. The presen...
BACKGROUND Few studies have reported delayed hypersensitivity reactions to systemically administered cephalosporins. The diagnostic procedures and extracts for these reactions are not standardized, and little is known about the extent of cross reactivity among different cephalosporins. CASES REPORT We report 2 cases of delayed hypersensitivity reactions due to cephalosporins presenting as ery...
