[Radiographic study of the oesophagus of chagasic patients in 25 years of the Mambaí Project].

This work describes radiography studies of the esophagus in chagasic patients of the Mambaí project over a 25 year period. Each person realized two radiographs in four different periods (1975-1976, 1980-1982, 1988-1991 and 1998-2000). The first radiograph was realized in the right anterior oblique position after swallowing 75 ml of barium sulphate solution and another 60 seconds later.

[Evaluation of the impact of vector control of Chagas disease through serological testing in Mambaí/Buritinópolis, Goiás State].

In 1999, we performed serological and entomological surveys to evaluate the impact of vectorial control measures against transmission of Chagas' disease in the endemic area of Mambaí and Buritinópolis (GO). A census was undertaken of the population, after which the entomological survey was performed regarding the dwelling units and serological evaluation of the human population. Blood samples were collected by digital puncture in filter paper.

Evaluation of the impact of chemical control measures and entomological surveillance on Chagas' disease in the counties of Mambaí and Buritinópolis, Goiás State, Brazil.

Epidemiological surveillance activities were implemented in 1980 in Mambaí and Buritinópolis counties, Goiás State. Twenty years later the authors evaluated the impact of these vector control measures on Chagas' disease transmission, based on entomological indicators. Entomological investigation was conducted using the man-hour technique and covering all domiciles.
