Cefazolin broad spectrum

The standard treatments used for non-Hodgkin's lymphoma are localised radiotherapy for early-stage disease and chemotherapy with CHOP. Autologous stem cell transplants are used for selected groups of patients. Transplants from matched donors are rarely used for NHL. Developments in treatment include the use of several newer drugs as single agents for earlystage disease and various methods of immunotherapy. The prognosis for non-Hodgkin's lymphoma depends on the type and stage of disease at the time of diagnosis. DRUG-INDUCED HEMOLYTIC ANEMIA IN A CAT. L. A. Snyder1, A. J. Birkenheuer2, J. Neel1, C. B. Grindem1. Departments of 1Population Health and Pathobiology and 2Clinical Sciences, North Carolina State University, College of Veterinary Medicine, Raleigh, NC, USA. Acute hemolytic anemia developed 6 hours after a single perioperative dose of injectable cefazolin in a 3-year-old cat. Hemolyzed serum and hemoglobinuria, as well as a decrease in PCV from 51% to 28%, were noted. Mycoplasma haemofelis PCR was negative. Hemolysis resolved within 24 hours of discontinuing antibiotic therapy. Direct and indirect antiglobulin testing with the patients cells, serum, and drug-sensitized RBCs confirmed drug-associated hemolytic anemia. Additionally, antiglobulin positivity was observed in one of two healthy control cats without previous exposure to cefazolin. The introduction of 2nd and 3rd generation cephalosporins has increased the prevalence of drug-induced hemolytic anemia in human patients. Drug-induced hemolytic anemia is an uncommon, but serious complication that veterinarians should consider in patients that develop hemolytic anemia.

Cefazolin CZ ; is much more susceptile to inactivation by Staphylococcus aureus betalactamase than cephalothin CF ; 7 ; , raising doubts about the usefulness of CZ in staphylococcal endocarditis 2 ; . This study compares the efficacy of CZ, CF, and methicillin M ; in the therapy of left-sided endocarditis in rabbits, caused by a highly penicillin-resistant, methicillin-susceptible strain of S. aureus, which rapidly inactivates CZ in vitro.

Peared to originate from the capsule Fig. 2 ; . The cells became filaments after 2 h of exposure to 0.1 , ug of cefotiam per ml Fig. 3a ; , and at 0.39 to 1.56 , tg ml, spheroplast-like structures together with filaments were formed Fig. 3b and c ; . After 4 h of exposure to cefotiam, spheroplast-like structures appeared even at a concentration of 0.1 yg ml, and at higher concentrations, the spheres became more swollen and collapsed Fig. 3d through f ; . The morphological alteration of the cells exposed to cefazolin for 2 h was almost the same as that observed with cefotiam; filaments developed at concentrations near the minimal inhibitory concentration, and spheroplast-like structures or bulges were formed as the concentration rose Fig. 4a through c ; . Bulges besides filaments emerged at 1.56 lAg of cefazolin per ml after 4 h of exposure, and at higher concentrations, disintegrated cell debris with vesicular conformation was observed Fig. 4d through f ; . The control cells of K. pneumoniae DT-S that were examined by ultrathin sectioning gave an appearance of gram-negative bacilli. The cell wall was made up of an outer triple-layered membrane and an intermediate layer of murein. In the cytoplasm, clustered ribosomes and dispersed nuclear regions were seen. After 2 h of exposure to 0.1 to 0.39 yg of cefotiam per ml, the cells became filaments, while the appearance of the cell surface profiles and the cytoplasm were relatively unchanged. At 1.56 Mg of the cephalosporin per ml, prominent morphological changes occurred: many cells turned into spheroplasts, and as for the cells with bacillary form, both the outer and plasma membranes broke; additionally, the density in the cytoplasm rose, possibly by condensation of the cytoplasmic contents. The cytoplasm of the cells became sparse, and scattered electron-dense lumps were seen after 4 h of exposure to cefotiam. Among the cells which turned into a spherical form, some possessed the outer membrane whereas others lost it. After exposure to 1.56 to 6.25 Mug of cefazolin per ml for 2 h, the cells became filaments and plasmolysis occurred. In addition, the electron density in the cytoplasm rose enormously, and the condensed nuclear regions showed abnormal distribution. At 25 Mug of the cephalosporin per ml, spheroplasts and disintegrated cell debris were observed. After 4 h of exposure to cefazolin, electron-dense lumps and many membranous structures were often noted in the sparse cytoplasm data not shown ; . Morphological response in vivo. Scanning electron microscopy of a cross section of a lung sample after 34 h of infection showed distribution of infecting organisms. At the central part of the lesion, the organisms localized densely in and cerezyme.

Formulary update, from page 1 Cefoxitin, a second-generation cephalosporin, was added in the Formulary when cefotetan, the current second-generation cephalosporin listed in the Formulary, was discontinued by its manufacturer. Cefotetan orders will be automatically interchanged to cefoxitin. For surgical prophylaxis, cefoxitin will be interchanged on a milligram-formilligram basis. However, because cefoxitin has a shorter half-life than cefotetan, cefoxitin will have to be given more frequently than cefotetan for moderate and severe infections. For moderate to severe infections when cefotetan 2 grams IV every 12 hours is prescribed, cefoxitin 2 grams IV every 6 hours will be dispensed. For severe infections when cefotetan 3 grams IV every 12 hours is prescribed, cefoxitin 2 grams IV every 4 hours will be dispensed. As with all therapeutic interchanges, a note will be placed in both the Orders and Progress Notes sections of the chart to alert the prescribers and nursing staff of this interchange. Although cefotetan is still considered the preferable second-generation cephalosporin, its unavailability made this change necessary. Cefoxitin is available only in limited quantities. Therefore, it is recommended that its use be limited to pre- and peri-operative therapy. Cefazolin plus metronidazole is an alternative for intra-abdominal infections and gynecological surgeries. Metronidazole's anti-anaerobic activity will cover organisms like Bacteroides fragilis, which are covered by cefoxitin and cefotetan ; . Cilostazol is a phosphodiesterase type 3 inhibitor approved for treatment of intermittent claudication. It decreases platelet aggregation, formation of arterial thrombi, vascular smooth-muscle proliferation, and causes vasodilatation. The American College of Chest Physicians' ACCP ; 2004 guideline for the symptomatic treatment of chronic limb ischemia recommends a limited role for cilostazol. Cilostazol is recommended for patients with disabling intermittent claudication who do not respond to conservative measures ie, risk factor modification and exercise ; and who are not candidates for surgical- or catheter-based interventions. Cilostazol should not be used with less disabling claudication. A meta-analysis of 8 randomized, placebo-controlled trials of cilostazol in patients with stable, moderateto-severe claudication, ranging from 12 to 24 weeks in duration, found and cefazolin.
