The best remedy for warts of the skin could be found in stationery stores. A simple piece of tape that completely covers the wart seems to be as effective or more therapeutic than cryotherapy with liquid nitrogen, according to a small study of children and young people published in the Archives of Pediatric and Adolescent Medicine of the American Medical Association.
The study results show that 85% of patients using an adhesive or heat produces complete removal of warts., Compared to 60% in the case of those receiving cryotherapy. Besides the inconvenience of doctor visits, another problem with cryotherapy is the fear and pain it causes in children, according to the study’s lead author, Dean R. Focht, Medical Center of Cincinnati Children’s Hospital (USA).
“The study shows that occlusion with adhesive tape exceeds the efficacy of cryotherapy in the treatment of common warts and may be a cheaper alternative, convenient and painless,” say the researchers. Despite evidence of the result, experts know the exact mechanism by which to obtain, but suspect ‘may include stimulation of the immune system of patients with localized irritation’.
This study included 51 patients from 3 to 22 years. Those who received treatment with duct tape, a nurse covered the wart with a piece the same size as the wart. It also instructed the patients or their parents, to keep the tape for six consecutive days. At the end of the sixth day, patients had to soak and rub the wart with an emery board or pumice stone. The next morning the patients had put a new tape. This process was repeated for two months at most.
