Community-acquired Pseudomonas aeruginosa Osteomyelitis Caused by an Injury from a Dishwasher

Abstract

A 70-year-old healthy woman came to our hospital with right index finger pain and swelling after an injury incurred due to a commercial dishwasher. X-ray of the hand showed osteolysis around the distal interphalangeal joint. A further examination revealed Pseudomonas aeruginosa in the unexposed pus, so the patient was treated with a total of 10 weeks of cefepime, followed by levofloxacin and debridement twice. While this may have been a case of bacterial replacement, we should still consider P. aeruginosa infection in healthy adults when faced with an episode of waterborne injury.
