Clinical studies of Nd:YAG laser and Chinese herbal medicine in treatment of patients with tinea unguium

摘要

Forty-seven patients with tinea unguium and 110 tinea unguium, proven bacteriologically and pathologically, were treated with an Nd:YAG laser and Chinese herbal medicine, after which they were analyzed. All patients were adult men and women. The duration of illness varied from 1 to 10 years. The patients were treated with Nd:YAG laser wavelength 1.06 $mu@m and the ending output power 500 w/cm$+2$/. The diseased nail was removed by laser scanning or cauterization, charring, gasification and coagulation layer by layer until the nail matrix was exposed, and then it was bandaged with a small amount of Chinese herbal medicine. The cure rate is 80.0%. The tinea unguium infection rate of pars super finialis is very high in cities, accounting for more than 80% of the cases among the population. It influences patients' lives and finger appearance. However, removal of tinea unguium with Nd:YAG laser cauterization and coagulation is simple, painless, and does not require disinfection. Also, the reoccurrence rate is low. Treatment of tinea unguium is intractable. Oral administration of griseofulvin and ketoconazole are not completely satisfactory and hardly persist for a long-term treatment course. Moreover, long-term administration of these drugs might produce serious side effects such as renal injuries, leukopenia, psychosis, etc. Thus, we conclude from this data that Nd:YAG laser and Chinese herbal medicine are an effective treatment for hypertrophic scarand kiloid and valuable for further investigations.
