13. Seroreactivity to new Mycobacterium leprae protein antigens in different leprosy-endemic regions in Brazil
New Mycobacterium leprae protein antigens can contribute to improved serologic tests for leprosy diagnosis/classification and multidrug therapy (MDT) monitoring. This study describes seroreactivity to M. leprae proteins among participants from three highly endemic leprosy areas in Brazil: central-western Goiânia/Goiás (GO) (n = 225), Rondonópolis/Mato Gro

14. The combination of three faecal parasitological methods to improve the diagnosis of schistosomiasis mansoni in a low endemic setting in the state of Ceará, Brazil
Laboratory diagnosis of intestinal schistosomiasis mansoni can be accomplished through various methods of stool examination to detect parasites, ranging from the most classic tests (Kato-Katz) to several methods that are still undergoing validation. This study was conducted to assess two new parasite identification methods for diagnosing schistosomiasis mans

15. Avaliação de pacientes com hanseníase na faixa virchowiana diagnosticados entre 1990 e 2000 e tratados com poliquimioterapia 24 doses e seus comunicantes na fase pós-eliminação em municípios de Santa Catarina / Assessment of lepromatous leprosy patients diagnosed among 1990 and 2000 and treated with multidrugtherapy 24 doses and their household contacts in the post-elimination phase in Santa Catarina municipalities
INTRODUÇÃO: A poliquimioterapia (PQT-OMS) para tratamento da hanseníase resultou em drástica redução da sua prevalência, mas em limitado impacto na detecção de casos novos (CN), que se manteve estável em Santa Catarina, estado na fase de pós-eliminação. Casos com altos índices baciloscópicos apresentam risco de recidiva tardia e podem consisti

16. Effectiveness of confidential unit exclusion in screening blood donors of the regional blood bank in Londrina, Paraná State
BACKGROUND: For transfusion purposes, blood donors must be accepted both in clinical and serological evaluations and must not have excluded their own donation using the confidential unit exclusion. AIMS: The objective of this study was to verify whether blood donors who choose self exclusion are more likely to be positive in serological tests than donors who

17. Serologic evidence of the recent circulation of Saint Louis encephalitis virus and high prevalence of equine encephalitis viruses in horses in the Nhecolândia sub-region in South Pantanal, Central-West Brazil.
As in humans, sub-clinical infection by arboviruses in domestic animals is common; however, its detection only occurs during epizootics and the silent circulation of some arboviruses may remain undetected. The objective of the present paper was to assess the current circulation of arboviruses in the Nhecolândia sub-region of South Pantanal, Brazil. Sera fro

18. Chronic hepatitis virus infection in patients with multiple myeloma: clinical characteristics and outcomes
OBJECTIVES: Cytotoxic agents and steroids are used to treat lymphoid malignancies, but these compounds may exacerbate chronic viral hepatitis. For patients with multiple myeloma, the impact of preexisting hepatitis virus infection is unclear. The aim of this study is to explore the characteristics and outcomes of myeloma patients with chronic hepatitis virus

19. Diagnostico molecular da Leishmaniose visceral canina: avaliação do swab conjuntival em cães assintomáticos e em cães vacinados / Molecular diagnosis of canine visceral leishmaniasis: conjunctival swab evaluation in asymptomatic dogs and vaccinated dogs
The epidemiological control of visceral Leishmaniasis (VL) in Brazil involves the elimination of infected dogs. Therefore, reliable diagnostic tests are essential to prevent the transmission of the disease or unnecessary culling of dogs. The VL control in Brazil is based on serological surveys, nevertheless serologic assays present problems related to sensit

21. Valores de ferritina sérica em beta talassemia heterozigota
A low iron level, the commonest nutritional deficiency in the world, is a public health problem in developing countries. On the other hand, an excessive amount of iron is toxic, causing several organic dysfunctions, such as diabetes, cirrhosis, endocrinopathies and heart disease. Researchers have reported an association of iron overload with beta-thalassemia

22. Avaliação de um modelo animal para estudo da infecção pelo vírus da dengue / Evaluation of an animal model for study of dengue virus infection
Dengue is the arbovirus (arthropod-borne viral disease) more widespread in tropical and subtropical countries. According to World Health Organization estimates that more than 100 million cases occur annually worldwide. Based on serologic tests of dengue viruses are classified into four antigenically distinct serotypes (DENV-1, DENV-2, DENV-3 and DENV-4). The

23. Transmissão vertical do HIV em população atendida no serviço de referência em Maceió - Alagoas / Vertical transmission of HIV in the population treated at a referral hospital in Maceio - Alagoas
Introduction: the evolution of the Acquired Immunodeficiency Syndrome epidemic in Brazil brought a challenge to control the Human Immunodeficiency Virus (HIV) vertical transmission. The vertical or mother-child transmission of HIV is a route exposure which has multiple causes and the influence of factors associated with transmission of the virus varies accor

24. Prevalência da doença celíaca em crianças desnutridas, na faixa etária de 12 a 36 meses
Background: The correct diagnosis of celiac disease (CD) in environmentally deprived children is frequently hindered by the common presence of other causes for the classical CD symptoms: malnutrition, failure to thrive and frequent diarrheas. Objectives: To determine the prevalence of CD in a group of 12 to 36 month-old children using immunoglobulin antibodi
