Pseudomas

1. [noun] pseudomonas, also known as chloronychia or green nail syndrome, are characterized by green discoloration of the nail plate (greenish-yellow, greenish-brown, greenish-black), proximal chronic non-tender paronychia, and distolateral onycholysis. The cause is Pseudomonas aeruginosa infection of the nail plate. This may occur with people who have their hands constantly exposed to water, soaps, and detergents or are subject to mechanical trauma, especially in the elderly. Green or black coloration of the nails should raise suspicion for Pseudomonas infection and be treated with an oral quinolone (ciprofloxacin), particularly in aged patients. NOTE: FOOT CARE NURSES SHOULD NOT PERFORM FOOT CARE ON THE "GREEN NAIL". REFER TO DR. OR PODIATRIST FOR TREATMENT

Frequently Asked Questions

How can one identify the nail discoloration associated with pseudomonas infection on the foot?

The infection often presents with a greenish tint ranging from yellow to black on the nail plate. This color change is noticeable along with a slight lifting of the nail border, a hallmark sign for differentiating from other nail issues.

Is green nail syndrome always due to a fungal infection on the foot?

No, green nail syndrome is typically linked to a bacterial cause, specifically pseudomonas aeruginosa. Its presentation can be confused with fungal conditions, but the greenish discoloration along with nail separation helps clarify its bacterial origin.

How does the term ‘pseudomonas’ help in remembering the nature of this foot infection?

The prefix ‘pseudo-’ means false, which reminds us that although the condition might be mistaken for other nail infections, its true bacterial nature is due to pseudomonas aeruginosa. This etymological hint aids in distinguishing it from more common fungal issues.

What everyday activities might increase the risk for developing this type of nail problem on the foot?

Activities involving prolonged exposure to water, detergents, or mechanical stress can weaken the nail’s protective barrier, making it more susceptible to pseudomonas colonization. Being mindful of these daily exposures is key to understanding this nail issue.
