BACKGROUND: Periungual warts are a therapeutic challenge. Many studies have revealed that intralesional interferon α-2b therapy and pulsed dye laser therapy have numerous advantages over other modalities of theratment. OBJECTIVE: The purpose of this study was to determine if combination therapy with intralesional interferon α-2b and pulsed dye laser might offer an effective treatment for periungual warts. METHODS: Thirty-three patients were randomly assigned to one of three study groups. In group A, the patients received both intralesional interferon α-2b treatment and pulsed dye laser(PDL) therapy (n=13). Group B patients were treated wit intralesional interferon α-2b alone (n=10) and group C was done with PDL therapy only (n=10). RESULTS: The clearance rate was 92.3% for the patients treated with the combination therapy of intralesional interferon α-2b treatment and pulsed dye laser (PDL) therapy. It was 50% for the patients with the intralesional interferon α-2b treatment alone, and 0% for the group with the PDL therpy only. No significant side effects were observed. At 6 months after cessation of the therapy, total 2 cases (one from group A and the other from group B) were recurred. CONCLUSION: The combination therapy with intralesional interferon α-2b treatment and pulsed dye laser therapy was highly effective for the treatment of recalcitrant periungual warts.

Dental restorative materials must have the physical properties to withstand wear and corrosion. Base metal alloys possess better mechanical properties and lower price than the gold alloys. For these reason such alloys have largely replaced the precious metal alloys. One aspect to consider is the release of metal substances to oral environment. The release of elements from dental alloys is a continuing concern because the elements may have the potentially harmful biological effects on local tissue. The purpose of this study was to minimize metal release on the nonprecious metal surfaces by ion bea assisted deposition(IBAD) of titanium nitride (TiN). Ni-Cr-Be alloys with and without TiN coatings were secured in an wear test machine opposing ruby ball to determine their relative resistance to wear with 100m, 200m, 300m and 400m sliding distance. And the corrosion behavior of the Ni-Cr-Be alloys with and without TiN coating and 3 dental noble alloys have been studied. Potentiodynamic curves were used to analyse the corrosion characteristics of the alloys. The measurement of the released Ni and Ci ions was conducted by analysis of the electrolyte solution with atomic absorption spectroscopy. The results were as follows : 1. The critical sliding distance that wore down TiN coating of 2.5micrometer thickness in this study condition was 300m. 2. Ion beam assisted deposition of TiN showed a good surface modification with respect to the properties of wear and corrosion resistance. 3. X-ray diffraction showed that the strongest peak of TiN(111) in the coatings. 4. The release of Ni and Cr ions from alloys measured by means of atomic absorption spectroscopy was reduced by ion beam assisted deposition of TiN.
