Cryotherapy may not SEEM to be as effective as it might be because of the way different clinicians apply it. A liquid nitrogen cold-burn which goes sufficiently deep enough to kill all the infected cells is very painful, akin to a cigarette burn. When a doctor applied this technique to a wart on my hand, the surface layers of the wart did die off and flake away after a few days, but the wart recurred in a couple of months. I found by treating myself that a very painful burn with repeat applications of liquid nitrogen on one occassion seemed to get rid of the wart permanently. It could be that doctors are being too gentle. —unsigned by 62.6.139.11 15:32, 18 August 2006.

Based on referenced information I've added to the article, I'm guessing that you sent the virus into remission, but didn't eliminate it. Warts may recur even after effective treatment. I don't think the doctor was too gentle; you can cause permanent nerve and tissue damage with cryosurgery. —{admin} Pathoschild 18:49:24, 27 February 2008 (UTC)

As far as treating these things... I think we should add something about the banana peel method. It sounds like an old wives tale, but it's true: a doctor told me to tape a piece of banana peel on my foot and cut away dead skin. I did this for about two or three weeks, and the wart fell off.

Utter tosh.

Does said doctor float in water? ;-) I think the problem is that it's impossible to know if your wart simply fell off naturally. Chris 15:29, 26 August 2005 (UTC)[reply]

"Fell off"? I've had warts, and I've had them disappear after several years. But I've never known one to "fall off". It was more that the entire cluster, which had grown for about five years, unexpectedly shrank and disappeared in less than two weeks. Is "fell off" meant to be taken figuratively, or is my experience totally unusual?

Information in articles must be reliably referenced. —{admin} Pathoschild 18:53:49, 27 February 2008 (UTC)

They should be treated right away because they can spread in clusters. As for treatment garlic definatley works garlic oil contains a potent substance called allicin, which blocks key enzymes that aid bacteria and viruses in their effort to invade and damage tissues, cut a slice of garlic clove the size of the wart and attach it with adhesive tape for 24 hours this definatley helps heal along with regular treatments from a dermatologist who can freeze it with nitro.

I have two comments to add:

First, about the banana peel method, there is a reference on the left side of http://www.plantar.org about this method.

Second, here is a holistic method to remove plantar warts: see this link http://home.access4less.net/~wart/plantar/Plantar-Foot-Wart.html

I have a comment to add:

I just treated my daughters wart with duct tape!@ I was skeptical at first but it worked amazingly well. Here is a link to a small article at the Mayo Clinic : http://www.mayoclinic.com/health/plantar-warts/AN00739

Right before I put duct tape on the wart it was irritated and all the skin around it was red and slightly warm. Within 2 days that was gone and then over the next week and a half or so the wart itself dried up, shrivelled and then just came off stuck to the duct tape. All we did was rip off a square and stuck it on the area and replaced the square whenever it fell off. We never filed down the wart at all or otherwise messed with it, motly because my daughter didn't want anyone to touch it! So far it hasn't shown any signs of coming back. It might be unscientific but I am absolutely positive the duct tape made it go away and wanted to share the information.

I have submitted medically accurate information about the treatment of warts Philiphughesmd 02:59, 13 February 2006 (UTC)[reply]

For 2006, modern treatment methods are not more than 75% effective. Does anyone have the source for this claim?

Yes, http://www.cochrane.org/reviews/en/ab001781.html seems to be widely referenced, and says:

• "...best available evidence...a cure rate 75%"
• "...the average cure rate of placebo preparations was 30%." --Snori 12:51, 9 May 2006 (UTC)[reply]

The main article wart has been flagged as being in need of help. Nearly all of the content in wart is redundant with plantar wart. Since plantar wart is better organized and more verifiable, I vote that plantar wart be used as the foundation for the merged article. It might also make sense to rename the merged article "Skin wart" or "Common wart" and have it cover all non-genital skin warts. Genital warts should be left a separate article, since they have a completely different etiology.Retroid 13:15, 22 May 2006 (UTC)[reply]

There are numerous types of wart including Common warts, Flat warts, Filiform warts, Mosaic warts, as well as plantar and genital [1]. I think wart should hold information common to all types with specifics of each type on separate pages. So, I'm not convinced that merging is a good idea. But I would agree that much information is being duplicated and this should be addressed. This would probably involve moving content from plantar wart into wart and vice-versa. Pgr94 08:47, 24 May 2006 (UTC)[reply]

Agree with Pgr94. --Arcadian 13:04, 24 May 2006 (UTC)[reply]

I see Pgr94's point - separate entries for the various wart types sounds like a good idea. Then "Wart" would become basically a glorified disambiguation page with links to the different wart types. Am I understanding correctly that you propose there be separate articles entitled "Common wart" and "Plantar wart?" I'm confused by that scenario. The current Plantar wart article covers the topic of common warts pretty thoroughly. Not sure what would go in the "Common wart" article that would be different.Retroid 23:16, 25 May 2006 (UTC)[reply]

My understanding is that they are different (but closely related) conditions and as such deserve their own page. Information needn't be duplicated - for instance there can be separate pages for commonalities like "keratolytic treatment of warts", "immunological treatment of warts", etc. Incidentally Retroid, as our resident HPV expert, can you tell us if common and plantar are the same HPV type? Pgr94 14:14, 30 May 2006 (UTC)[reply]

I’m surprised to find that the answer is it depends who you ask. Molecular biologists (like me) and epidemiologists (like PMID 16032719) tend to think of plantar warts a sub-class of common warts. For example, although HPV type 1 is usually associated with foot warts, you can also sometimes find it in hand warts. As mentioned in the current incarnation of Plantar wart, foot warts and hand warts are fundamentally similar phenomena. On the other hand, after a quick skim through PubMed I’m surprised to learn that clinical specialists draw a clear distinction between plantar warts and common warts (e.g., PMID 16127954 – note: free to the public – has a nice summary of treatment options for cutaneous warts [2]).

Interesting reference, Retroid (PMID 16032719). It would seem a nice neat hierarchical structure relating genotype to clinical condition simply may not fit. It's more a case of certain groups of host-genotype+virus-genotype being evolutionarily successful.

Glad you posted that link with the summary of treatment options. I found it a few weeks ago and liked it too, then lost it and have been looking for it since. I thought it would be good to incorporate a couple of the tables but was concerned about copyright issues. Pgr94 21:50, 5 June 2006 (UTC)[reply]

Anyway, good question, Pgr94. Helps me understand that even though a plantar wart may be the same biological phenomenon as a hand wart, the fact that people have to walk on the plantar warts merits a clinical distinction. So I think we now have consensus - separate pages for different wart types, with just "wart" being a type of disambiguation page.

Separate pages for different treatment options sounds difficult. All the treatments are conceptually similar - trying to wake up the immune system to see virus parts that are effectively hidden. The spectrum of available treatment options is basically the same for all cutaneous wart types (PMID 16127954). I think "Common wart" could have a section that compares and contrasts the different treatments (e.g., as current Plantar wart article does). Then the various wart types could refer to the treatment section of common warts.

I'm not opposed to that. My reasoning was that in the future there'd be sufficient content on each of the treatment options that they'd get an article of their own. Perhaps guilty of looking too far ahead... Pgr94 21:50, 5 June 2006 (UTC)[reply]

I'm also in favour of a main wart page with specifics on subpages for different entities like plantar wart. Maybe this topic could use a navigation box?--Steven Fruitsmaak | Talk 11:24, 14 August 2006 (UTC)[reply]

I say merge the two. Then, after that's done, let's merge all the various car articles (Chevrolet Camaro, Ford Mustang, et al) into the Automobile article; they're all just variants, after all. When that's finished, we can merge all the colleges and universities, all the mammals, all the planets, and so on. In fact, Wikipedia could just be one big article lumped under Everything. --BRossow 14:21, 28 September 2006 (UTC)[reply]

I've removed the merge tag, as consensus was not to merge, and added a stubby section to the warts article listing the various major types of wart, with a brief description. Espresso Addict 17:09, 28 September 2006 (UTC)[reply]

-It is unecessary to take such extreme measures as these listed above for plantar warts. Over-the-counter treatments (adhesives and at-home freeze therapy, see below...) work fine. If the wart is stubborn, however, a local clinic could treat the wart(s) in a matter of minutes. (see below, again.) User:Pittlers

These two statements seem contradictory to me:

"The ideal treatment for a viral-induced tumor (such as the HPV virus causing plantar warts), would be an anti-viral drug or an immunization against the virus. Unfortunately, for plantar warts, this is not currently available."

and

"Immunotherapy: using injected mumps, candida or trichophytin antigen USP or applied imiquimod cream ("Aldara") are new treatments."

Does anyone else agree/disagree? Pgr94 11:49, 5 June 2006 (UTC)[reply]

it would be more accurate if the first sentence said "virus-specific drugs or vaccination against the virus." The key unifying concept behind all currently-available wart treaments is that, in the context of the undisrupted wart, the virus is effectively hidden from the immune system. Cracking open the wart (cryotheraphy) or killing some infected cells (5-FU) or injecting generically inflammatory agents (Aldara) are just various ways of introducing virus parts into an environment where the immune system can recognize them as unusual and dangerous. There have been studies where they treated warts on one hand and observed that warts on the other hand were simultaneously cleared, suggesting immunological control (as opposed to physical removal of the wart) was the primary mechanism of clearance. Current treatments are very generic, blunt instruments. I guess you could call the current treatments a type of "auto-immunization." But they're such brute force processes that they don't belong in the same category as the terms "immunization" or "vaccine." Retroid 21:21, 10 June 2006 (UTC)[reply]

This article has become somewhat of a shambles. I've made a start, but it still needs work. I think a useful destinction could, and should, be made between "folk remedies", "common medical treatments" and "experimental medical treatments". I've made a little start on that track, but I'd like to review other medical articles to see how best to extend this approach. --Snori 17:16, 20 June 2006 (UTC)[reply]

I'm rather surprised you thought fit to erase the section on relative effectiveness of treatments. I have reverted, but we can discuss. Pgr94 18:40, 20 June 2006 (UTC)[reply]

Another thing gone missing during the tidy up are the complications of watchful waiting. "If untreated there may be complications. Warts may spread, develop into clusters or fuse to become mosaic warts." I again think this is useful info. Rather than deletion, I'd prefer we found references... Pgr94 18:52, 20 June 2006 (UTC)[reply]

I don't know how it fits with your tidy up plans, but at some point I had hoped to add some tables similar to those in this article [3]. See what you think. Pgr94 18:58, 20 June 2006 (UTC)[reply]

That table approach is excellent. Regards the "if untreated", it may just be a case of popping his in at the right place - it didn't seem to add much where it was, but maybe it could be the part of the intro, or appended to "watchful waiting"?--Snori 20:05, 20 June 2006 (UTC)[reply]

I don't think this section title is appropriate. Rx refers to prescription-only drugs and salicyclic acid is over-the-counter. I suggest changing back to "Pharmaceutic". Any objections? Pgr94 10:31, 10 August 2006 (UTC)[reply]

Rx is an abbreviation/shorthand and has many meanings. It is a specifically american view that it means 'prescription only drugs'. Also, some salicylic acid remedies for warts are only available by prescription in some countries. That being said, as shorthand, it is hardly appropriate for a heading in an encyclopedia. —Preceding unsigned comment added by 124.171.215.238 (talk) 14:33, 11 February 2008 (UTC)[reply]

If you own the rights on these pictures then you can upload them, otherwise they're not usable Pgr94 15:47, 28 December 2006 (UTC)[reply]

The photo at the top of the article right now appears to be warts on the top of the foot, not plantar warts on the bottom of the foot. Either the photo is not an accurate representation, or the description which defines plantar warts by their location on the sole of the foot is inaccurate. From prior information I've heard on the subject, I think it's the former possibility. In that case, the photo should be removed. --Icarus ^(Hi!) 08:53, 6 January 2007 (UTC)[reply]

I had a cluster of warts on my foot and sal acid treatment was doing nothing. Laser and/or burning couldn't be used because of the large area affected so I finally tried one of those "strange" natural remedies in the form a cream. Within a week the cluster had almost receeded and within two weeks it had dissapeared. The cream was some sort of plant extract in white-ish transparent form but I wasn't able to get a hold again of the person that gave it to me so I have no idea what it was. Can anyone here tell me?

I had the same problem 6 years ago, and I used a product similar to what you described. It was called something like "Miracle of Aloe," and it got rid of all the warts.

Unfortunately I cannot find any reliable sources about that treatment, so we cannot include it in the article. —{admin} Pathoschild 15:25:05, 07 August 2008 (UTC)

It probably won't work- I had a plantar wart (not a very large one) for many years, and if regular hot baths can be considered soaking they had no affect except to make the callused tissue surrounding the wart swell, temporarily causing greater discomfort in walking.

• the best treatments are those containing salicylic acid. They are clearly better than placebo.
• there is surprisingly little evidence for the absolute efficacy of cryotherapy.
• two trials comparing salicylic acid and cryotherapy showed no significant difference in efficacy.
• one trial comparing salicylic acid and duct tape occlusion therapy showed no significant difference in efficacy.

How is it possible there is "surprisingly little evidence for the absolute efficacy of cryotherapy" How is it possible "the best treatments are those containing salicylic acid", while "two trials comparing salicylic acid and cryotherapy showed no significant difference in efficacy" and "there is surprisingly little evidence for the absolute efficacy of cryotherapy"? If there is no difference in efficacy, how can a salicylic acid treatment be the best?

That is not a contradiction. The study was an overview of past trials whose results could differ. It found that salycylic acid was most effective overall (73%), while there was no evidence of the absolute effectiveness of cryotherapy. However, two particular studies comparing salycylic acid to cryotherapy found no significant difference between the two.

Removed from the article because not verifiable:

• Although not mentioned in medical texts, distilled white vinegar is a common solution. Soak either a cotton ball or cotton pad with distilled white vinegar then adhere to the areas of infection with medical tape (easiest when done at night during sleep). Within one to two weeks, depending on severity of each case, the wart will fall off.

Pgr94 23:04, 27 June 2007 (UTC)[reply]

I can't find any reliable sources supporting this remedy. According to "Vinegar: Medicinal Uses and Antiglycemic Effect" (Carol S. Johnston), application of very high concentrations of acetic acid (up to 99%) does alleviate warts, presumably due to the mechanical destruction of wart tissue, but vinegar has a low concentration of acetic acid (typically 5–18%, or roughly 40% when distilled). "Skin Disease in Organ Transplantation" (Clark C. Otley, Thomas Stasko) notes that white vinegar is useful in defining the extent of HPV infection due to its acetowhitening effect, but makes no mention of its use in treatment.

I have removed the following pending a verifiable source.

• Weight-Load Walking: The patient wears a backpack weighing 40 pounds (17.5 kg), and walks non-stop for 8.1 miles (13 km), completing the walk in 2 hours 25 minutes. This is done once a week. Painful blisters may occur in the first few weeks, and last a day or two after completing the walk. Due to accelerated exfoliation the plantar warts may also fall off within a few weeks. A comforable backpack with a frame is strongly recommended to prevent excessive soreness in the shoulders. Comfortable shoes and extra-thick socks are also strongly recommended. Numerous side benefits of weight-load walking include low-impact fat-burning, the expenditure of approximately 1000 Calories, increased upper-body strength, increased endurance, increased muscle efficiency, improved walking form, improved cardiovascular fitness, and improved general health.

How does the Plantar Wart virus leave an affected person? Through the wart? Through feces? Through bodily fluids like other HPV viruses?

Does a wart form where the virus enters? The sole of the foot is so thick I find it hard to believe even the smallest cut necessary to let the virus enter would go unnoticed. 68.81.119.160 (talk) 03:16, 27 February 2008 (UTC)[reply]

The virus enters through tiny cuts or abrasions in the stratum corneum (outermost layer of skin); it does not require a deep cut. The wart forms at the location it entered, and can be pushed deeper into the skin by the pressure of walking. It is the warts which are contagious; I haven't found mention of contagion through other bodily fluids in my research. —{admin} Pathoschild 21:40:15, 07 August 2008 (UTC)

I have reverted these edits because they have removed factual information obtained from peer-reviewed scientific journals. It is a step backwards to remove such material unless it is replaced with better sources. The changes are too extensive to separate the wheat from the chaff. Can I suggest making less extensive changes, and removing no facts unless they lack verification or are demonstrably wrong. Pgr94 (talk) 19:46, 27 February 2008 (UTC)[reply]

Actually, I may have been a bit hasty there. The references that I initially thought stripped were not, just moved around significantly. I'm struggling to make out what has changed in the article between sections being moved around, new text being added, text being removed.

The references added to support new material are other encyclopaedias (emedicine or hipusa). Peer-reviewed scientific publications are preferable.

• are plantar warts really "generally harmless"? HPV is known to cause some types of cancer, is there evidence that this doesn't happen with plantar warts?

Pgr94 (talk) 20:21, 27 February 2008 (UTC)[reply]

Hello Pgr94. Other HPV types are harmful, but plantar warts do seem to be generally harmless according to the current references. I've seen some unelaborated references to benign HPV becoming malignant (as you've noted), but I'm not sure whether that's normally relevant to these types (1, 2, 4, or 63) or the result of other factors. We should look into that to make sure.

Most of the changes are additions and referencing, with some reorganization. Very little (if any) content was removed. Scientific journals can be good sources, but so are encyclopedic sources; there's no reason not to use both. :) —{admin} Pathoschild 00:45:55, 28 February 2008 (UTC)

Doing some research into this, Dr Penelope Bridger explains the references we noticed: "In the general population, cutaneous warts are harmless, transient tumours caused by about 8 types of human papilloma viruses (HPV)" [...] "Longterm immunosuppression, for example among renal transplant recipients, and patients with the rare disease Epidermodysplasia Verruciformis (EV) are at risk of their warts undergoing malignant change. However, such malignancies are in-situ or invasive squamous cell carcinomas which are slow growing and non-metastasising. The HPV types found in these skin cancers are not the ones found in common skin warts. Malignant transformation of skin warts found in the general population has never been reported." [...] "There is no evidence that warts are potentially harmful, except in immunocompromised patients whose warts need monitoring, or patients with EV, which is very rare."

So it seems that plantar warts are indeed harmless; the malignant changes mentioned are not caused by the plantar warts or underlying infection, although epidermodysplasia verruciformis is believed to be caused by infection from other types of HPV not contributing to plantar warts. —{admin} Pathoschild 04:00:09, 28 February 2008 (UTC)

Malignancy transformation: Thanks for the reference and the comment you quote Pathoschild. I would be wary of attaching too much importance to that source because it is based on an old (1990) virology textbook which in turn is based on even older publications. (Bear in mind that at that stage the HPV hadn't been sequenced). Secondly, I'm not sure it is even peer-reviewed.

This 2006 article PMID 16943705 and this 2007 review PMID 17553059 would be a great help to get a more recent perspective. Unfortunately, I have access to neither :-( Pgr94 (talk) 09:19, 28 February 2008 (UTC)[reply]

I have access to those articles, and can send you copies if you give me your email address.

PMID 16943705 (Malignant Transformation of Plantar Verrucae) states:

PMID 17553059 (The oncogenic potential of human papillomaviruses: a review on the role of host genetics and environmental cofactors) discusses malignancy of HPV types at greater length than I can fairly quote, so I'll only quote the most relevant sections:

In so far as I understand the articles, it seems that some HPV types do cause cancer, but not those associated with plantar warts. Although there is at least one case of a plantar wart becoming malignant, this seems to have been caused by other factors rather than the HPV infection, and could just as well have affected other benign lesions like scars or ulcers. I'll send you copies if you email me, so you can draw your own conclusions. —{admin} Pathoschild 01:31:44, 29 February 2008 (UTC)

Thanks for obtaining this information, Pathoschild. I hope it was a copy-and-paste job and not typed in! Have sent you mail and look forward to reading the articles. Pgr94 (talk) 12:45, 29 February 2008 (UTC)[reply]

Sent. (Yes, I copied and pasted the quoted text. :) ) —{admin} Pathoschild 13:24:32, 29 February 2008 (UTC)

I'm surprised that there's no mention of one of the oldest and most successful treatments. It's not a medical treatment though, since I doubt if anyone has made any research, but using Greater celandine's yellow 'juice' from the stem works perfectly. I've seen it used many times, I even experienced this treatment and it really worked. The plant has been brought to North America by puritans and it's as common as in Europe now. But people are unaware of the method, which is really working, is cheap and painless. Warts die in a few days and as soon as new skin grows underneath, they fall off. Don't consider this as bullshit, please. —Preceding unsigned comment added by Czuken (talk • contribs) 11:46, 18 March 2008 (UTC)[reply]

If there's no research backing up the information, we can't add it the article. Wikipedia's core policies require verifiability and reliable sources for any information added. —{admin} Pathoschild 19:07:32, 18 March 2008 (UTC)

There's no mention under the treatment section of hypnosis. I've read quite a few journal articles indicating hypnosis has a fairly high success rate of treating plantars.Friskyfountains (talk) 23:42, 27 October 2008 (UTC)[reply]

You'd need citations for that, because if it shows up on the page without reliable sources, I am certainly going to remove it per WP:PROVEIT. WLU (t) (c) ^{(rules - simple rules)} 01:58, 28 October 2008 (UTC)[reply]
