Cryotherapy for Warts

If warts must be treated in pregnancy, cryotherapy appears to be the best choice. Cryotherapy involves application of nitrous oxide or liquid nitrogen (-196°C) to genital warts, inducing dermal and vascular damage and edema, and leading to both epidermal and dermal cellular necrosis.

Liquid nitrogen can be poured into a container with a applicator (cryoprobe) to form a cryostat unit. Liquid nitrogen is then sprayed onto wart until it turns white, indicating that it is frozen; the subsequent thaw produces cell lysis. Two freeze/thaw cycles are usually undertaken, but trials have not established the optimal number of applications.

Discomfort is moderate enough so that anesthesia is not needed. In fact, there are several other methods of performing cryotherapy. Liquid nitrogen may be applied directly to warts with a cotton-tipped swab. Cryotherapy may be used for any anogenital wart that is accessible to treatment. The advantage of cryotherapy include ease of application and rapid destructive effect.

It may have special advantage in treating bulky lesions, grouped lesions, and lesions on hair-bearing areas. It does not have systemic side effects and only affects tissue to which it is directly applied. Following cryosurgery, treated areas require local care only and treated areas may be cleaned. Scar formation is rarely significant. Pigmentary alterations in the short term are not uncommon but usually (but not always) normalize.

Genital warts on the prepuce, especially flat genital warts, have a greater predilection for scarring and fibrosis after treatment. Healing usually occurs in 1-2 weeks after cryotherapy, although sometimes complete healing may take more than eight weeks. Based on a study of 34 pregnant women treated with cryotherapy, three to four treatments of cryotherapy appear to be safe.

Cryotherapy is effective. Trials show genital wart clearance rates from 79-88 percent with recurrences in 25-39 percent despite multiple treatments. Most warts cleared with fewer than three treatments. Cryotherapy is relatively inexpensive. The equipment required for office cryosurgery using liquid nitrogen includes a Dewar flask with dispensing valve and a cryogen, all costing $1,000-3,000.

However, this cure for warts is not always successful. In fact, warts may recur after using a common wart cure because of the activation of latent virus present in healthy skin adjacent to the lesion. Most patients with warts require multiple warts cure treatments over a course of several weeks or months.

If substantial improvements have not occurred after 3 physician-administered treatments or if complete clearance has not occurred after 6 treatments, a different treatment modality should be used. For warts, cures used to treat HPV disease are applied topically on cutaneous surfaces. Local skin reactions and pain are common adverse effects.

More difficult warts may have to be surgically excised or burned off. Once surgical intervention or chemical acids are used one can expect a scar in that area. One all-natural topical warts cure -- WartCure exhibits a broad spectrum of action against HPV, the virus that causes warts. It kills HPV and provides a curative effect against warts.

For warts, cures don't come much better than WartCure. It is established to eradicate and cure warts time after time. It is one of the most powerful and effective topical cures for warts on the market. Results are guaranteed. It is comprised of certified organic medicinal plant extracts and certified organic antiviral essential oils that have been demonstrated to kill HPV in laboratory tests.

The therapeutic action of WartCure is accomplished via its rapid absorption into the skin. For warts, cures must act quickly in skin tissue. The organic essential oils in WartCure are lipophilic (absorb into fatty tissue such as the skin) and have a low molecular weight. This allows them to pass readily into skin tissue and into the DNA of cell membranes where they attack and destroy the HPV virus.

Further, certain herbal extracts contain antiviral alkaloids, yet not in essential oils, and purposely blended into WartCure. These antiviral alkaloids are known to penetrate human tissue, meaning that for warts, cures are effected almost immediately. To learn more, please go to http://www.bcured.net.
