Current Management of Onychomycosis and Dermatomycoses.

Three newer oral antifungal agents, itraconazole, terbinafine and fluconazole, have revolutionized treatment of superficial mycoses. The tissue pharmacokinetics of itraconazole and terbinafine allow much shorter courses of therapy- with higher efficacy-in the treatment of onychomycosis, compared to other oral agents. Itraconazole pulse dosing and terbinafine daily dosing have shown comparable efficacy against dermatophyte onychomycosis; similar itraconazole regimens have been effective against nondermatophyte infections. Refractory clinical patterns of nail disease appear to be more responsive to oral antifungal therapy when combined with adjunctive therapy, such as debridement. These agents are effective against cutaneous dermatophytosis, with shorter treatment regimens. Tinea versicolor may be treated with a single-dose, intermittent, or daily regimen of an oral azole agent, depending on the drug selected. These newer oral antifungal agents have been proven effective against tinea capitis; effective regimens are shorter than those for griseofulvin. The safety profile of these newer agents has been very favorable.

Epidemiology of dermatomycoses of humans in central Poland. Part III. Tinea pedis.

The total number of dermatophytoses (7393) included 2025 (27.4%) tinea pedis cases. Etiological factors in descending order by contribution were: Trichophyton rubrum (41.7%), Trichophyton mentagrophytes var. granulosum (30.9%), T. mentagrophytes var. interdigitale (10.0%), Epidermophyton floccosum (7.4%), T. mentagrophytes var. quinckeanum (6.9%), Trichophyton tonsurans (2.3%), Trichophyton spec. (0.4%), Trichophyton terrestre (0.2%), Trichophyton violaceum (0.1%). In the years 1987-93 the incidence of tinea pedis substantially increased over 1994-96. Today tinea pedis is second by incidence among all clinical forms of dermatophyte infections of skin and skin appendages in the Lódź region.

Ciclopirox: a new topical pyrodonium antimycotic agent. A double-blind study in superficial dermatomycoses.

One percent Ciclopirox solution, a new topical antimycotic agent, was used in a double-blind controlled trial in 105 dermatomycosis patients. Twelve of the patients were lost to follow-up. Of the remaining ninety-three patients, forty-four were treated with the active drug, forty-nine with a placebo. The cure rate amongst those using ciclopirox was significantly superior to that of the placebo. The drug was effective against Trichophyton rubrum, T. violaceum, T. mentagrophytes and Malassezia furfur.

Relevance of broad-spectrum and fungicidal activity of antifungals in the treatment of dermatomycoses.

The in vitro fungistatic and fungicidal activities of terbinafine, amorolfine and itraconazole against dermatophytes were compared. All three compounds showed very good activity against all dermatophyte species tested, but only terbinafine and amorolfine exhibited primary fungicidal activity. These two compounds were also active in vitro against other filamentous fungi which cause onychomycoses, such as Scytalidium and Scopulariopsis species.

Chronic dermatomycoses of the foot as risk factors for acute bacterial cellulitis of the leg: a case-control study.

OBJECTIVE: To assess the role of foot dermatomycosis (tinea pedis and onychomycosis) and other candidate risk factors in the development of acute bacterial cellulitis of the leg. METHODS: A case-control study, including 243 patients (cases) with acute bacterial cellulitis of the leg and 467 controls, 2 per case, individually matched for gender, age (+/-5 years), hospital and admission date (+/-2 months). RESULTS: Overall, mycology-proven foot dermatomycosis was a significant risk factor for acute bacterial cellulitis (odds ratio, OR: 2.4; p < 0.001), as were tinea pedis interdigitalis (OR: 3.2; p < 0.001), tinea pedis plantaris (OR: 1.7; p = 0.005) and onychomycosis (OR: 2.2; p < 0.001) individually. Other risk factors included: disruption of the cutaneous barrier, history of bacterial cellulitis, chronic venous insufficiency and leg oedema. CONCLUSIONS: Tinea pedis and onychomycosis were found to be significant risk factors for acute bacterial cellulitis of the leg that are readily amenable to treatment with effective pharmacological therapy.
