Previous issue date: 2008-08-02The health conditions of Brazilian indigenous population are few recognized with limited information available. A survey was carried out among indians Terena, people that inhabit on the municipalities of Sidrolândia and Dois Irmãos do Buriti, Estado de Mato Grosso do Sul, Brazil. Was studied the prevalence of infection by intestinal parasites, infection markers for viral Hepatitis A, B and C, and for antibody against the viral diseases; Poliomyelitis 1, 2 and 3, Measles, Yellow Fever and Hepatitis B. The results were stratified by age and revealed that the parasitic infection affects 73.5% of the population studied, with high prevalence of the Blastocystis hominis. In the population above 10 years, more than 90% showed reactivity to the anti-HAV, absence of infection markers for Hepatitis B and C, respectively HBsAg and anti-HCV, and a rate of 16.7% (95% CI 12.6-21.3) for the anti-HBs. The prevalence of neutralizing antibodies against the measles virus and yellow fever virus was 96.7% (95% CI 93.9-98.3) and 91.4% (95% CI 88.0-94.7) respectively. The polio results showed that 62.2% (95% CI 56.5-67.6) 71.7% (95% CI 66.2-76.6) and 63.5% (95% CI 56.5-69.6) had antibodies against the types 1, 2 and 3, respectively, showing vulnerability to B Hepatitis, Yellow Fever and Poliomyelitis.As condições de saúde da população indígena brasileira são pouco conhecidas, ocorrendo uma escassez de informações sobre a questão. Para estabelecer um entendimento dos aspectos que compõem esse panorama, foi realizado um inquérito entre os índios Terena que habitam os municípios de Sidrolândia e Dois Irmãos do Buriti, Estado de Mato Grosso do Sul, Brasil. Foram estudadas as prevalências de infecção por parasitos intestinais, de marcadores de infecção para as Hepatites virais A, B e C, e de anticorpos contra os vírus das enfermidades imunopreveníveis; Poliomielite 1, 2 e 3, Sarampo, Febre Amarela e Hepatite B. Os resultados foram estratificados por faixa etária e revelaram que a infecção parasitária acomete 73,5% da população estudada, com destaque para o encontro do Blastocystis Hominis, um agente pouco identificado no país. Na população acima de 10 anos, mais de 90% apresentaram reatividade para o anti-HAV total. Houve negatividade dos marcadores de infecção para as Hepatites B e C, respectivamente HBsAg e anti-HCV, e uma taxa de 16,7% (95% IC 12, 6-21, 3) para o anti-HBs.A prevalência de anticorpos neutralizantes contra o vírus do Sarampo e da Febre Amarela foi de 96,7% (95% IC 93, 9-98, 3) e 91,4% (95% IC 88-94, 7) respectivamente. Em relação à Poliomielite, 62,2% (95% IC 56, 5-67, 6) 71,7% (95% IC 66,2-76, 6) e 63,5% (95% IC 56, 5-69, 6) apresentavam anticorpos contra os Poliovírus tipo1, 2 e 3, respectivamente, demonstrando vulnerabilidade dessa população à Hepatite B, à Febre Amarela e à Poliomielite
Intestinal protozoa and helminths among Terena Indians in the State of Mato Grosso do Sul: high prevalence of Blastocystis hominis
A parasitological survey was carried out among Terena Indians living in the Tereré settlement in the municipality of Sidrolândia, State of Mato Grosso do Sul, Brazil. Single samples of feces from 313 Indians were processed by means of the spontaneous sedimentation method. In the population studied, 73.5% were infected with at least one intestinal parasite or commensal. Protozoa predominated. Blastocystis hominis (40.9%), Entamoeba coli (33.2%) and Entamoeba histolytica/Entamoeba dispar (31.6%) were the most common. Bivariate analysis showed that females were generally more infected and presented higher rates of infection by Entamoeba histolytica/Entamoeba dispar and Entamoeba coli. Males were more infected by hookworms and Strongyloides stercoralis than females. The precarious sanitary conditions of the Tereré settlement are probably a contributory factor towards the high prevalence of intestinal protozoa
Paracoccidioidomicose: estudo clínico e epidemiológico de 422 casos observados no Estado de Mato Grosso do Sul Paracoccidioidomycosis: a clinical and epidemiological study of 422 cases observed in Mato Grosso do Sul
São descritas as características clínicas e epidemiológicas de 422 casos de paracoccidioidomicose atendidos no Hospital Universitário da Universidade Federal do Mato Grosso do Sul (Campo Grande, Mato Grosso do Sul, Brasil) no período de Janeiro de 1980 a Agosto de 1999. A média de idade foi de 43,4 anos e a proporção homem: mulher foi de 10:1. Quase metade (45,5%) dos doentes era trabalhadora rural no momento do diagnóstico. A forma aguda/subaguda (tipo juvenil)(15,4% dos casos) revelou-se com importante comprometimento do sistema fagocítico-monocitário, manifestado principalmente por adenomegalia (95,4%); hepatomegalia (40%); esplenomegalia (23,1%). A forma crônica (tipo adulto)(84,6% dos casos) apresentou-se com maiores proporções de lesões em orofaringe (66,4%); rouquidão (31,4%) e tosse (50,7%). Para o diagnóstico, foram utilizados o exame micológico direto em 365 pacientes e o histopatológico em 302, com positividade de 50,7% e 97,3%, respectivamente. O tratamento antifúngico preferencial foi a associação de sulfametoxazol e trimetoprim (co-trimoxazol), utilizado em 90,3% dos doentes. Seqüelas foram observadas em 30,3% e óbito em 7,6% dos casos.<br>Clinical and epidemiological features of 422 cases of paracoccidioidomycosis attended at University Hospital of Universidade Federal de Mato Grosso do Sul (Campo Grande, Mato Grosso do Sul, Brazil) from January 1980 to August 1999, were analysed. The mean age was 43.4 years old and the male: female ratio was 10:1. Nearly half (45.5%) of the patients were agricultural workers at the moment of diagnosis. In the acute/subacute form (juvenile type) the phagocytic-monocytic system was very much impaired and mainly marked by lymphadenopathy (95.4%), hepatomegaly (40%), splenomegaly (23.1%). The chronic form (adult type) presents more lesions in oropharynx (66.4%), dysphonia (31.4%) and cough (50.7%). Mycological diagnosis was obtained by direct microscopy of wet mounts in 185/365 (50.7%) patients and by histopathological examination of biopsies in 294/302 (97.3%) patients. The treatment of choice was Sulfamethoxazole/ trimethoprim (Co-trimoxazole), used in 90.3% patients. Sequelae occurred in 30.3% and death in 7.6% of the cases
NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics
Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths. Our data set includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the southern United States, Mexico, and Caribbean countries at the northern portion of the Neotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n = 5,941), and Cyclopes sp. have the fewest (n = 240). The armadillo species with the most data is Dasypus novemcinctus (n = 11,588), and the fewest data are recorded for Calyptophractus retusus (n = 33). With regard to sloth species, Bradypus variegatus has the most records (n = 962), and Bradypus pygmaeus has the fewest (n = 12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other data sets of Neotropical Series that will become available very soon (i.e., Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans data set. Please cite this data paper when using its data in publications. We also request that researchers and teachers inform us of how they are using these data
