Autologous tumor lysate/Bacillus Calmette-Guérin immunotherapy as an adjuvant to conventional breast cancer therapy.

Introduction: Autologous tumor cell vaccines rely on the concept of preserving an individual's own tumorigenic makeup, expressing its unique set of tumor-associated antigens as well as antigenic elements from the surrounding stroma. These autologous tumor characteristics are usually presented with an immune adjuvant in the hopes of enhancing an immune response.

Methods: The autologous vaccine we used was composed of tumor cells combined with BCG and formalin.

Intermediate cutaneous leishmaniasis caused by Leishmania (Viannia) braziliensis successfully treated with fluconazole.

American cutaneous leishmaniasis is an endemic anthropozoonosis that exhibits a broad spectrum of clinical presentations. Intermediate/borderline disseminated cutaneous leishmaniasis is a distinct clinical condition that comprises cutaneous disease of a chronic nature, usually occurring as multiple lesions with or without mucosal involvement. The disease is usually caused by parasites of the subgenus Viannia, frequently occurs in context of an underlying disease, and is often resistant to standard antileishmanial therapy.

Interruption of Onchocerca volvulus transmission in Northern Venezuela.

Background: Onchocerciasis is caused by Onchocerca volvulus and transmitted by Simulium species (black flies). In the Americas, the infection has been previously described in 13 discrete regional foci distributed among six countries (Brazil, Colombia, Ecuador, Guatemala, Mexico and Venezuela) where more than 370,000 people are currently considered at risk. Since 2001, disease control in Venezuela has relied on the mass drug administration to the at-risk communities.

Serologic follow-up of IgG responses against recombinant mycobacterial proteins ML0405, ML2331 and LID-1 in a leprosy hyperendemic area in Venezuela.

Leprosy is a slowly evolving disease that occurs mainly in adults. In this study, the Mamaría Village, state of Portuguesa was selected because it had one of the highest prevalence rates (13.25%) of leprosy cases in 1997.
