BACKGROUND Knowledge of the relationship between specific geographical differences and histopathology of the American cutaneous leishmaniasis is limited because host-parasite interactions in space and time are complex. OBJECTIVE To describe the geographic analysis of the histopathological pattern of localized American cutaneous leishmaniasis and the(More)
This study shows the effectiveness of photodynamic therapy based on methylene blue dye for the treatment of endonyx toenail onychomycosis. Four patients with endonyx onychomycosis caused by Trichophyton rubrum were treated with 2% methylene blue aqueous solution irradiated with light emission diode at 630 nm and an energy density of 36 J/cm2 for 6 months at(More)
