Hi All,

I have just come across a comment re black nail varnish. Has anyone used it on verruca with Salicylic 70%?

Seemly it cuts out light and oxygen? How to strangle to death a Wart perhaps after 5,000 years!

Regards,

Colin.

Dear Colin,

In these days of evidence based practice and peer review i wonder how this would sit.

If we use eveidence then the most effective treatment is NOTHING this is about 90% effective over a several month period.

I believe Cryo with Liquid Nitrogen comes next.

This is followed by Curretage excision with Electro Dessication

This is followed by Placebo eg buy it for a fiver.

Then come the particularly barbaric vicious caustics.

As an anecdote i still favour 95% Silver Nitrate Stick applied after gross edbridement. This is fairly uncomfortable for the poor pt but has its merits.
But as i have not t/t VP's for about 3 years as my PCT no longer t/t's VP's the above is based on memory.

regads David

Hi All,

Quote:- "I wonder how this would sit."

Probably with raised eyebrows and a few, "Tut,tuts!"

Desperation perhaps?

95% Silver nitrate stick, Interesting. Result black covering of the Verruca. Works possibly by shutting out the light and starving the surface of oxygen perhaps, that which is claimed for the black nail varnish and possibly "Duck Tape"?

Well I only asked!

Regards,

Colin.

Dear Colin,

95% Silver Nitrate is an Escharotic.

It works by removing all moisture from the tissue affected and thereby destroys the tissue leaving a dry crunchy eschar.

Salicylic acid works by forcing water into the tissues and thereby macerating the tissues and thus destroying the tissue.

Both of this damaged tissue can be carefully debrided with a scalpel.

Hi David,

Yes David you can see that which you described happening over time, but in the case of Silver Nitrate it always seemed to me that it was really confined to the surface with little or no penetration! I wonder if it is totally chemical damage whilst the verruca goes on it's merry way untouched by the reaction?

Regards,

Colin.

there is a topical drug made by dermik labs,called carac.it is intended for seborrheic keratosis.however,many derms and pods have used it to treat verruca vulgaris with very good results.it is prescribed to the patient for daily application with occlusion(duck tape works best).this is to be followed by weekly debridements in the office.
there is little discomfort to the patient and lesions usually resolve in 4 weeks.its mechanism of action is genetic(fluorouracil),rather than caustic.
