Objective: To supplement the information on the underlying cause of death due to external causes through using news carried in newspapers.

Methods: This study investigated 153 deaths due to external causes among people living in Belo Horizonte, Southeastern Brazil, in 2008. A database named "press" was constructed using information from large-circulation national and state-level newspapers, and this was correlated with the database of the Brazilian mortality information system.

Background: The cave fauna of the Brazil is poorly documented, and among the insects those live or frequent caves and their adjacent environments phlebotomine sand flies call for special attention because several species are vectors of pathogens among vertebrates hosts. A new species of sand fly from Minas Gerais is described based in females and males collected in a cave of the municipality of Lassance.

Results: The morphological characters of the new species permit to include in the Evandromyia genus, cortelezzii complex.

Phlebotomine sand flies are distributed across nearly all faunal regions of the world, represented by over 800 species, of which many are important vectors of human pathogens. Brazil is currently faced with the expansion and urbanization of leishmaniases, with an increase in the numbers of human cases and seropositive dogs in various medium-sized to large cities. The objective of the current study was to survey the phlebotomine sand fly species in an area endemic for American cutaneous leishmaniasis (ACL) and American visceral leishmaniasis (AVL), i.

The phlebotomine sandflies of the province of Chaco, Argentina, are poorly known, with reports from more than 40 years or captures related with outbreaks of leishmaniasis. In here, Mycropygomyia peresi (Mangabeira) is reported for the first time in Argentina, extending the known dstribution of Migonemyia migonei (França), Evandromyia sallesi (Galvão & Coutinho), Mycropygomyia quinquefer (Dyar), Brumptomyia brumpti (Larousse) y Nemapalpus spp to the province of Chaco.

There are nearly 500 species of sandflies in Americas, 30 of which are vectors of leishmaniasis. Evandromyia cortelezzii (Brèthes), E. sallesi (Galvão & Coutinho) and E.

Natural infections with Leishmania were found in females of the phlebotomine sand flies Lutzomyia neivai (Pinto) (= Nyssomyia neivai) and Lutzomyia sallesi (Galvão & Coutinho) (= Evandromyia sallesi) (Diptera: Psychodidae) from Lassance, in the Brazilian state of Minas Gerais. Promastigotes were found in the pyloric region of the former species and in the abdominal midgut of the latter species. Insects found to be infected by microscopic examination were macerated in saline solution and inoculated into hamsters.

In Brazil, Leishmania transmission involves several species of phlebotomine sand flies that are closely associated with different parasites and reservoirs, giving rise to different transmission cycles. The present study focused on naturally infected phlebotomines originating from Santa Luzia, a municipality near Belo Horizonte, capital of the Brazilian state of Minas Gerais, in which leishmaniasis are endemic. Systematic and non systematic approaches,involving the use of light traps and direct aspiration from resting sites, respectively, were used to collect females and flies.

Several species of the subgenus Psychodopygus Mangabeira, 1941 are known to be leishmaniosis vectors in Brazil. Some of them are morphologically similar, which makes their identification quite difficult concerning epidemiological studies. The aim of the current work is to study the morphology of adult specimens of the subgenus Psychodopygus, in accordance with the morphological similarity and still taking into account the epidemiological importance of some species.
