[Advantages of topical therapy with polydeoxyribonucleotide in reparative processes after cauterization: experience at a center for early diagnosis of genital neoplasms].

This paper evaluates the common practice of a topic medical treatment following cautery (or other kinds of microsurgery) of the uterine cervix. Firstly, a controlled clinical trial on 116 patients treated with kanamycin sulphate alternated to polydeoxyribonucleotide vaginal suppositories, and 124 controls has been conducted. Subjective parameters (leukorrhea, bloody discharge, odorous discharge, more than three weeks vaginal discharge, itching, pain, burning) and colposcopy (Schiller test reactivity, squamo-columnar junction location, abnormal transformation zones, vascular striae, deepithelialized areas or frail epithelium) appeared more favorable in the treated group, the colposcopic finding of phlogosis being the only unfavorable finding more frequent among the treated patients. Successively, a controlled double blind clinical trial with kanamycin sulphate alternated to placebo vs PDRN at different dosages has shown an increase in number of epithelial cells in the treated patients and a better stimulation of fibroblasts by higher dosages of active substance. These results show the efficacy of the studied post cautery treatment schedule, and of PDRN in particular.
