    We investigated the efficacy of 1064nm Nd:YAG laser for the treatment of onychomycosis caused by dermatophytes. The study population consisted of 12 patients (6 male, 6 female ; average age 53.5 years), with onychomycosis confirmed by fungal culture and/or real-time PCR identification of the pathogen. The causative agent was identified as Trichophyton rubrum in 11 cases and a mixture of T. rubrum and T. mentagrophytes in 1 case. For each patient, laser treatment was given to a single hallux nail, with turbidity at baseline affecting <75% of the nail surface and thickness at baseline <3mm. Treatment was given in 3 sessions at 4-week intervals, and nail turbidity was evaluated 3 and 6 months after the first laser treatment. After 6 months the efficacy results were as follows : 3 cases, turbidity significantly improved ( >70%) ; 2 cases, turbidity improved (50-70%), 1 case, turbidity slightly improved (30-50%) ; 5 cases, no change in turbidity (<30% improvement) ; and 1 case, turbidity worsened. Overall, the total lesion area with turbidity in 12 patients decreased from 664.4mm2 to 481.0mm2, corresponding to a 27.6% improvement after treatment. Pain during laser treatment was well tolerated, and all patients underwent all 3 treatments. These results suggest that the 1064nm Nd:YAG laser could be a useful treatment alternative for patients with mild onychomycosis.

    Prototheca zopfii is an achlorophyllic alga that is ubiquitous around cow sheds. The alga is associated with bovine mastitis, which causes a reduction in milk production and secretion of thin watery milk containing white flakes. Isolates of P. zopfii from bovine mastitis were almost all identified as P. zopfii genotype 2, suggesting that it is the main causative agent of bovine protothecal mastitis. The ability to differentiate between genotype 1 and genotype 2 is therefore very important for preventing bovine mastitis. In this study, high resolution melting real-time PCR (PCR-HRM) analysis of the protothecal 18S rDNA domain successfully differentiated between genotypes of P. zopfii in less than 3 hours, while conventional sequence analysis requires more than 48 hours to differentiate between genotypes. PCR-HRM analysis clustered P. zopfii genotype 1 isolates separately from P. zopfii genotype 2 isolates, indicating that this molecular typing method is an effective tool for rapidly diagnosing bovine protothecal mastitis.
