Common Wart, Plantar Wart
Conditions
Brief summary
Warts are benign epidermal tumors caused by human papilloma virus, which are epitheliotropic non-enveloped double stranded DNA viruses. Transmission of warts occurs from direct person-to-person contact or indirectly by fomites . Warts appear in various forms including verruca vulgaris, plane, plantar, filiform, digitate and periungual.
Detailed description
Treatment of warts is difficult for patients and physicians . Currently Available treatment options include cryosurgery, laser, electrosurgery, bleomycin, and topical keratolytic applications; many of them are painful, ineffective, costly and prone for recurrences. Cryotherapy, which uses liquid nitrogen to freeze tissues and destroy warts, is one of the most common and effective treatments. freezing causes local irritation, leading the host to mount an immune reaction against the virus. Immunotherapy appears to enhance virus recognition by immune system; allowing clearance of treated wart, distant warts , and helps to prevent infection .Recently, intralesional immunotherapy using different antigens such as mumps, Candida, and tuberculin has been proved effective in the treatment of warts. The exact mechanism of action of intralesional immunotherapy is still obscure. Intralesional antigen injection probably induces strong non specific inflammatory response against the human papilloma virus-infected cells. It has been suggested that intralesional measles mumps rubella vaccine results in regression of warts via induction of immune system.
Interventions
MMR vaccine will be injected 0.5 ml into the largest wart at 2-week intervals until complete clearance was achieved or for a maximum of 3 treatments. Response to treatment will be evaluated 1 month after the last session by decrease in the size of warts, decrease in the number of warts and photographic comparison. The clinical response was graded into complete (complete cure), partial (if there was a decrease in the size and\\or a decrease in the total number of warts), and no response (no change in size and number of warts).
PROCEDUREcryotherapy
patients received cryotherapy with liquid nitrogen once every 2 weeks until complete clearance or for a maximum of 3 sessions.Response to treatment will be evaluated 1 month after the last session by decrease in the size of warts, decrease in the number of warts and photographic comparison. The clinical response was graded into complete (complete cure), partial (if there was a decrease in the size and\\or a decrease in the total number of warts), and no response (no change in size and number of warts).
