Background: Nail thickening is a poor prognostic factor in onychomycosis. Mechanical reduction by micromotor nail grinding is an alternative treatment for onychomycosis. However, this treatment introduces a large amount of infected nail dust particles into the air and can adversely affect other patients and health-care providers. The innovative recirculating airflow safety cabinet (ASC) was developed to prevent the spread of these generated infected nail dust particles. The aim of this study was to determine the efficacy of the ASC in patients with onychomycosis or traumatic onychodystrophy. Methods: The ASC was used during the nail-grinding process in 50 patients, including 36 onychomycosis patients and 14 traumatic onychodystrophy patients. For each patient, five Sabouraud dextrose agar plates with chloramphenicol were positioned within the working space of the ASC, and the other five plates were positioned near the area of air exit after the carbon filters within the cabinet. A total of 500 plates were incubated at 25°C and evaluated every 7 days. The results of fungal cultures were analyzed. Results: In the traumatic onychodystrophy group, all fungal cultures of nail dust particles from both before and after filtration from the ASC were negative in all 14 patients. In the onychomycosis group, 52 fungal cultures (28.9%) from nail particles within the ASC working area tested positive; however, the results of fungal cultures of nail dust particles after filtration were all negative. Conclusions: The newly developed ASC was found to be effective for preventing the spread of infected nail dust particles generated by micromotor nail grinding to mechanically reduce nail thickness in patients with onychomycosis. |
