[Comparative analysis of health systems on the triple border between Brazil, Colombia, and Peru].

The objectives of this article are to describe the health sector reform process in Latin American countries and its impact on the health systems of Brazil, Colombia, and Peru; analyze the structure of the national health systems of these bordering nations; and assess the constraints and potential for integrating the local health systems along the triple Amazon border. Using official documents and databases, we analyzed health system development and the structure of the services network in this segment of the border located in the heart of the Amazon region. Comparison of the three countries confirmed that Brazil's model has the characteristics of a national public health system, while the Colombian and Peruvian models emphasize insurance systems, with the adoption of compulsory health care plans, the segmentation of users, and limitations on coverage.

[Leprosy in indigenous populations of Amazonas State, Brazil: an epidemiological study in the counties of Autazes, Eirunepé and São Gabriel da Cachoeira (2000 to 2005)].

Although this State has the largest indigenous population in Brazil, there are no data on the leprosy profile in these groups. This study aimed to describe and analyze the epidemiological characteristics of leprosy case reporting in the municipalities (counties) of Autazes, Eirunepé, and São Gabriel da Cachoeira, comparing indigenous and non-indigenous findings according to target variables.
