OBJECTIVE To evaluate voriconazole in the treatment of extensive cases of chromomycosis. Chromomycosis is a chronic infection, which is extremely difficult to eradicate, and is caused by dematiaceous (dark-colored) fungi which affect the skin and subcutaneous tissues, with Fonsecaea pedrosoi being the major etiologic agent. Drugs such as itraconazole,(More)
The sensitivity, specificity, positive predictive value, negative predictive value, and efficiency of immunofluorescence (IF) and enzyme-linked immunoassays (ELISA) for IgG, IgM and IgA antibodies were assessed on sera from mucocutaneous leishmaniasis patients and controls. The sensitivity of the IgG-ELISA test was 93.3% with 95% confidence interval higher(More)
Cell mediated immunity (CMI), bacterial index (BI), morphological index (MI), skin and lymph nodes biopsies were evaluated in 15 patients with virchowian hanseniasis before and after treatment with transfer factor (TF) obtained from human spleens. The patients were divided in 3 groups: group I (control) received only sulfone, group II received sulfone plus(More)
Chromoblastomycosis is a subcutaneous mycosis that remains a therapeutic challenge, with no standard treatment and high rates of relapse. On the basis of our recent discoveries in mouse models, we tested the efficacy of topical applications of imiquimod to treat patients afflicted with this chronic fungal infection. We report results of treatment for the(More)
The great toe was disinfected with alcohol 701. Distal block anesthesia was performed, infiltrating 2 mL of lidocaine 2% without epinephrine, and a tourniquet was applied. All of the granulation tissue was removed using a curette. The lateral nail plate was detached from the lateral and proximal nail fold using a nail elevator. The nail plate was cut down(More)
BACKGROUND Genital warts are caused by human papillomavirus infection and represent one of the most common sexually transmitted diseases. Many infections are transient but the virus may recur, persist, or become latent. To date, there is no effective antiviral treatment to eliminate HPV infection and most therapies are aimed at the destruction of visible(More)
Ten patients with donovanosis were treated with thiamphenicol for two weeks. In eight of them, included two HIV infected patients, lesions healed. The safety profile of thiamphenicol makes it a useful and cost-effective agent in the management of donovanosis. Randomized controlled trials should be conducted with these treatment options.
