Background. Practitioners have historically avoided cephalosporins and carbapenems in penicillin allergic patients. Despite recent literature suggesting a lower crosssensitivity than originally reported; practitioners continue to avoid cephalosporins and carbapenems in this patient population. The purpose of this study is to evaluate the tolerability of cephalosporins and carbapenems in patient...

The emergence and spread of resistance in Enterobacteriaceae are complicating the treatment of serious nosocomial infections and threatening to create species resistant to all currently available agents. Approximately 20% of Klebsiella pneumoniae infections and 31% of Enterobacter spp infections in intensive care units in the United States now involve strains not susceptible to third-generation...

BACKGROUND AND OBJECTIVES Various phenotypic methods are recommended in the routine practice to detect the ESBL production in gram negative bacilli. Among them, the Double Disc Synergy Test (DDST) which uses the third generation cephalosporins (3GC), is a simple and a reliable method. But the coexistence of AmpC may give false negative results. In such cases, the ESBL detection can be improved ...

Cephalosporins type antibiotics are widely used to treat infectious diseases. Their determination is not only important in blood/serum of patients under treatment but also in diverse matrices like wastewaters, milk etc. as contaminant. Keeping in view the need, a new high performance liquid chromatographic method for the determination of three cephalosporins (cefradine, cefuroxime and cefotaxim...

PURPOSE The aim of the study was the characterization of the electrophoretic behavior of cephalosporins from different generation having different structural characteristics in order to develop a rapid, simple and efficient capillary electrophoretic method for their identification and simultaneous separation from complex mixtures. METHODS Ten cephalosporin derivatives (cefaclor, cefadroxil, c...

Recent analysis of clinical data and a clearer understanding of the role of chemical structure in the development of cross-reactivity indicate that the increased risk of an allergic reaction to certain cephalosporins in penicillin-allergic patients is smaller than previously postulated. Medline and EMBASE databases were searched using the following keywords: cephalosporin, penicillin, allergy, ...

OBJECTIVE To evaluate the prevalence of extended-spectrum beta-lactamases isolates over one year period at Sultan Qaboos University Hospital. METHODS We identified the ESBL isolates during a 12-month period from July 2004 to June 2005, using a commercial system, and confirmed the result using the National Committee for Clinical Laboratory Standards-approved double-disk diffusion method.
