V.A.C. therapy should be considered as the treatment of choice for chronic leg ulcers owing to its significant advantages in the time to complete healing and wound bed preparation time compared with conventional wound care. Particularly during the preparation stage, V.A.C. therapy appears to be superior to conventional wound care techniques.
An open, randomized trial was performed to determine the optimal dosage schedule with regard to the efficacy and safety of cyclosporin in severe atopic dermatitis. The study also provided clinical experience with regard to the efficacy and safety of long-term cyclosporin treatment. During a 2-month dose-finding period, 78 patients with severe, long-standing atopic dermatitis received cyclosporin at a dose of either 5 mg/kg per day, decreasing to 3 mg/kg per day (Group A), or 3 mg/kg per day, increasing to 5 mg/kg per day (Group B), Patients were maintained on their optimal dose for a further 10 months. Patients in Group A showed a significantly greater improvement in efficacy parameters over the first 2 weeks than with patients in Group B, but as the dose was decreased in Group A and increased in Group B, these differences were minimized. After 1 year, cyclosporin showed an efficacy of 59.8% in Group A and 51.7% in Group B, assessed by a severity score. Assessed in terms of an area score, these figures were 48.7% and 40%, respectively. Cyclosporin demonstrated a good safety profile during long-term treatment and was generally well tolerated. The lower starting dosage was not associated with higher dropout rates. This study showed no differences in efficacy or adverse events between the two dosage schedules in long-term treatment.
Terbinafine is an allylamine antifungal compound shown to be effective in the oral treatment of onychomycosis. Because of the fungicidal activity of the drug, a shorter duration of treatment, compared with the currently used oral treatment modalities, can be expected in onychomycosis of the toenail. In the present randomized study, the efficacy of oral terbinafine treatment (250 mg/day) was assessed for periods of 6, 12, and 24 weeks. All patients were followed for up to 48 weeks after starting treatment. Of the 120 patients with toenail onychomycosis who entered the study, 98 were evaluable for efficacy. The involvement of the toenails was assessed both clinically and mycologically throughout the study. Evaluation at 24 weeks showed that complete cure of toenail onychomycosis was achieved in 67% of patients treated for 6 weeks, 82% treated for 12 weeks, and 85% treated for 24 weeks. At the end of a further 24 weeks of follow-up, cure rates were 40%, 71% and 79%, respectively. The adverse effects of terbinafine were mostly mild-to-moderate gastrointestinal symptoms. Three patients discontinued treatment because of side-effects. In conclusion, oral treatment with terbinafine is effective and generally well tolerated in patients with onychomycosis. Our results demonstrate that, for toenail onychomycosis, a treatment period of 12 weeks is sufficient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
