The Gram-negative bacterium Pseudomonas aeruginosa is an important life-threatening nosocomial pathogen in burn units. In this study we analysed epidemic P. aeruginosa isolates from patients and their hospital environment using two new molecular techniques in order to establish strain relatedness for epidemiological purposes. One technique was pyoverdine typing by isoelectric focusing (PVD-IEF) and the other was a genomic PCR-based fingerprinting technique called random amplification of polymorphic DNA actually referred to as RAPD-PCR. ⋯ The study demonstrates the applicability of the techniques in a routine microbiology lab as well as their usefulness, in combination with other techniques, in the fight against nosocomial infections, which are so critical in burn units. Both techniques showed undoubtable evidence of the occurrence of polymicrobial infection of individual patients by P. aeruginosa species. Meanwhile pyoverdine typing by IEF seems suited to studying more profoundly the role of pyoverdines in burns.

The purpose of the present study was to analyse the course of patients hospitalised with electrical burn wounds in the past 25 years at a major children's hospital in the United States in order to devise safe and cost effective management strategies for these patients. The study was a retrospective chart review of patients with electrical injuries admitted to the hospital between 1971 and 1995. We identified 127 children who were included in the study. ⋯ A retrospective review revealed that the great majority of patients with low voltage electrical injuries did not need admission to the hospital and could have been cared for on an outpatient basis. Almost every patient with high voltage injury had a justified admission due to the severity of the injury. On the basis of these results we conclude that we can safely reduce the number of admissions to the hospital for children with low voltage minor electrical injuries.
