Successful combined therapy with Glucantime™ and pentoxifylline for the nasal mucosal lesion recently developed in a leishmaniasis patient having untreated cutaneous lesion for seven decades.

Leishmaniasis is a worldwide problem and has been neglected in a wide range of fields, from diagnosis to treatment. This report describes a case of mucosal leishmaniasis, which may developped after seven decades of an inadequately treated cutaneous lesion. A female patient, 79 years old, from the non-endemic area for leishmaniasis in northern Paraná, presenting mucosal lesion in the nose and throat, reported an "angry ulcer" treated inappropriately as a child when she lived in an endemic region of the state of São Paulo. Indirect immunofluorescence and direct parasite screening were positive. Polymerase chain reaction detected a parasite belonging to the subgenus Leishmania (Viannia) sp. Due to patients limitations, such as low weight and advanced age, the therapeutic model adopted was the combined small doses of Glucantime™ to pentoxifylline, which ensured treatment success.

Systematic review and meta-analysis on Schistosoma mansoni infection prevalence, and associated risk factors in Brazil.

We performed a systematic review and meta-analysis on the prevalence and factors associated with Schistosoma mansoni infection in Brazil. We searched the PubMed, Web of Science and Latin-American and Caribbean System on Health Sciences Information (LILACS) databases, scientific publications articles, according to The PRISMA Statement, from 2000 to 2016. A total of 27 studies were included according to the established criteria. The prevalence of S. mansoni infection varied widely, from 0·1 to 73·1%, based on Kato-Katz technique. Of the identified studies, 42·9% were performed in the state of Minas Gerais, and 33·3% were performed in the northeast region of Brazil. We identified sex, age, education level, family income, contact with water and the presence of the intermediate host snail as major risk factors associated with infection. The meta-analysis summarized a high prevalence rate pooled for Schistosoma mansoni. On the other hand, the analysis of the subgroup showed a highly significant reduction of the prevalence rate after control measures. The epidemiological factors evidenced in the studies show the influence of environmental and social conditions on the occurrence of schistosomiasis.
