Parasite species variation and impact of spatial displacement of the population on cutaneous leishmaniasis in Rio de Janeiro, Brazil.

Background: Cutaneous leishmaniasis results from complex interactions between human beings, vectors and the environment. Parasitic species differ in epidemiological and geographical contexts.

Methods: We studied a retrospective cohort of 696 patients with cutaneous leishmaniasis treated at a reference centre in the state of Rio de Janeiro, Brazil, between 2000 and 2015.

Clinical features and therapeutic response in adult and pediatric patients with American tegumentary leishmaniasis in Rio de Janeiro.

Background: American tegumentary leishmaniasis (ATL) is a neglected disease with wide territorial distribution. Knowledge is scarce in children and adolescents. This study aims to compare the clinical features and response to antimony treatment in pediatric and adult patients with cutaneous leishmaniasis.

Comparison between systemic and intralesional meglumine antimoniate therapy in a primary health care unit.

Cutaneous leishmaniasis (CL) is not a life-threatening condition. However, its treatment can cause serious adverse effects and may sometimes lead to death. Recently, safer local treatments have been included among therapies acceptable to New World CL cases, but the use of intralesional meglumine antimoniate (IL-MA) is recommended to be performed in reference centers, for patients with single cutaneous lesions <3 cm in diameter at any location except the head and periarticular regions; the volume of injected MA should not exceed 5 mL.

Good response to pentamidine isethionate in a case of Mucosal Leishmaniasis caused by Leishmania (Viannia) braziliensis that was difficult to treat: Case Report.

In Brazil, meglumine antimoniate is the first drug of choice for mucosal leishmaniasis treatment followed by amphotericin B and pentamidine isethionate. We report the case of a patient with severe mucosal lesions caused by Leishmania (Viannia) braziliensis that were difficult to treat. Over a 14-year period, the patient showed low adherence and three treatment attempts with meglumine antimoniate failed.

Effect of secondary infection on epithelialisation and total healing of cutaneous leishmaniasis lesions.

Background: Cutaneous leishmaniasis (CL) generally presents with a single or several localised cutaneous ulcers without involvement of mucous membranes. Ulcerated lesions are susceptible to secondary contamination that may slow the healing process.

Objective: This study verified the influence of non-parasitic wound infection on wound closure (epithelialisation) and total healing.
