ABSTRACT
Cisto de erupção é um cisto de tecido mole decorrente de uma dilatação do espaço folicular em torno da coroa do dente em erupção, causado pelo acúmulo de líquido ou de sangue. Quando a cavidade cística que circunda a coroa do dente contém sangue, a lesão é denominada hematoma de erupção. O objetivo deste trabalho foi relatar dois casos clínicos de hematomas de erupção, assintomáticos, um relacionado à dentição decídua e o outro à dentição permanente. O tratamento dos casos foi baseado no acompanhamento, sem necessidade de intervenção cirúrgica e foi observada a correta erupção dos dentes.
Eruption cyst is a soft tissue cyst, resulting from dilation of the follicular space around the crown of the erupting tooth, caused by the accumulation of fluid or blood. When the cystic cavity surrounding the crown of the tooth contains blood, the lesion is called an eruption hematoma. The objective of this study was to report two clinical cases of asymptomatic eruptive hematomas, one related to deciduous dentition and the other to permanent dentition. The treatment of the cases was based on follow-up, without the necessity of surgical intervention and the correct eruption of the teeth was observed.
ABSTRACT
Abstract Chagas disease reactivation has been a defining condition for acquired immune deficiency syndrome in Brazil for individuals coinfected with Trypanosoma cruzi and HIV since 2004. Although the first coinfection case was reported in the 1980s, its prevalence has not been firmly established. In order to know coinfection prevalence, a cross-sectional study of 200 HIV patients was performed between January and July 2013 in the city of Pelotas, in southern Rio Grande do Sul, an endemic area for Chagas disease. Ten subjects were found positive for T. cruzi infection by chemiluminescence microparticle immunoassay and indirect immunofluorescence. The survey showed 5% coinfection prevalence among HIV patients (95% CI: 2.0-8.0), which was 3.8 times as high as that estimated by the Ministry of Health of Brazil. Six individuals had a viral load higher than 100,000 copies per µL, a statistically significant difference for T. cruzi presence. These findings highlight the importance of screening HIV patients from Chagas disease endemic areas.
