cefotaxime and Muscular-Diseases

Myonecrosis due to Aeromonas spp is exceptional. We report the case of a diabetic patient with liver cirrhosis who developed a rapidly progressive myonecrosis by Aeromonas veronii biotype sobria. The portal of entry was an injury after falling down in an irrigation canal. The outcome was not favourable and surgical amputation of left leg was performed in spite of antibiotic treatment with cefotaxime and tobramicin. Aeromonas spp can be very aggressive and this microorganism should be considered in the differential diagnosis of skin and soft tissue infections with myonecrosis, specially after posttraumatic wound infections with a history of freshwater exposure.

Four local irritation studies of cefodizime sodium (THR-221), a new developed cephem-type antibiotics, were carried out with NZW rabbits. 1. In eye irritation test, 25% THR-221 water solution had no irritancy on eye mucosa in rabbits. 2. In single injective intramuscular irritation study, regardless of solvents (water or 0.5% lidocaine), 25% THR-221 solution had irritancy equal to 0.75% acetic acid. But recovery process of the muscle injured with THR-221 was faster and better than with 0.75% acetic acid. 3. In five days injective muscular irritation study, the irritancy of 25% THR-221 water solution on the muscle was milder than that of CTT or CET. Histopathological damage with THR-221, necrosis/degeneration of muscle fibers and edema/hemorrhage in interstitium etc., were well recovered. 4. In vessel irritation study, 10% or more THR-221 water solution had irritancy on ear vessel. THR-221, as same as CTT, caused organized thrombi and inflammation at the surrounding area. The degree of irritation of 20% THR-221 solution was slightly stronger than that of 20% CET, but weaker than that of 20% CTT. 5. In a clinical phase, it is to be desired that THR-221 like as CTT or CET shall be avoided repeated intramuscular or intravenous injections at the same site.
