Abstract: a prospective study was undertaken in 1,520 children less than 15 years of age in s?o josé de ribamar, maranh?o, brazil, from june 1994 to january 1995, to evaluate the prevalence and characteristics (socioeconomic, environmental, and behavioral) associated with infection by leishmania chagasi. montenegro skin test (mst) and enzyme-linked immunosorbent assay (elisa-rk39 and crude) test were used to detect infection. the statistical analysis used the c2 test with yates correction and a p value less than 0.05 was considered statistically significant. prevalence of infection was 61.7% as measured by mst, 19.4% according to elisa (rk39), and 19.7% by elisa (crude). association was detected between leishmaniasis in the family, water supply, application of insecticide, and infection by l. chagasi using mst. no association with infection by l. chagasi was detected using elisa rk39 or crude. more effective control measures are needed to reduce prevalence and to detect asymptomatic cases in this high percentage of infected children.

Abstract: comparative study regarding igg and ige anti-leishmania as markers of infection and illness among residents of a visceral leishmaniasis visceral leishmaniasis endemic area, s?o luis, ma in the period from may 1999 to may 2000. all the 1,016 individuals younger than 16 years old were tested for the presence of igg by elisa. a total of 174 (17,1%) children revealed a positive igg test and 4 children showed symptoms of classical visceral leishmaniasis during the time of the survey: 85 ige anti-leishmania elisa tests with positivity of 43,5% were realized. in this sample, all 7 children with past-visceral leishmaniasis in the sample were igg positive and 4 (57,1%) were ige positive, even after a 7 year post treatment period. three children with current visceral leishmaniasis were evaluated, and all of them were positive for both tests. the detection of antileishman ige antibodies presented as a good marker for infection by leishmania chagasi in endemic areas but not as a disease marker.

Viana, Graa Maria de Castro;Diniz Neto, Jo?o Arnaud;Furtado, Igor de Sousa;Binda Júnior, José Roberto;Tanaka, Bárbara Neiva;Nascimento, Maria do Desterro Soares Brand?o;
Brazilian Journal of Infectious Diseases , 2008, DOI: 10.1590/S1413-86702008000600018
Abstract: htlv-i is associated with a broad spectrum of manifestations, including tropical spastic paraparesis and adult t-cell leukemia/lymphoma. arnold chiari syndrome is a condition characterized by herniation of the cerebellar tonsils through the foramen magnum. this condition should be suspected in all patients with headache and impaired motor coordination. syringomyelia is a developmental anomaly that leads to the formation of an intramedullary cavity. its clinical presentation is classically characterized by syringomyelic dissociation of sensation, with suspended distribution in the proximal portion of the trunk and upper limbs and preservation in other regions. we report here a case of association of the three diseases, which is rare in clinical practice, illustrating the difficulty in the diagnosis and therapeutic management of these conditions.

Abstract: introduction: one of the important current problems in hiv/aids infection is the establishment of epidemiological and laboratorial prognostic parameters during patient follow-up. this study aimed at analyzing the evolution of laboratory tests: cd4 lymphocyte count, viral load, hemoglobin (hb), aspartate aminotransferase (ast), alanine aminotransferase (alt), and the epidemiological variables sex and age as prognostic factors for survival in progression to death among aids patients. methods: a retrospective study was conducted using analysis of medical records, and prospective 24-month follow-up of patients with hiv/ aids attended at the president vargas hospital outpatient clinic, a reference center in hiv/ aids attendance in the state of maranh?o, brazil. the study analyzed patients aged 10 to 60 years old, who manifested aids and who were not using antiretroviral therapy or had used it for less than 5 years. the chi-square test was used for statistical analysis. results: the sample included 100 patients - 57 were current outpatients, and 43 had died. the variables viral load (p=0.726), alt (p=0.314), sex (p=0.687), and age (p=0.742) were analyzed, and no evidence of association between them and worst prognosis was observed. conclusions: a significant relation was verified between low hb levels (p=0.000) and cd4 (p=0.000) and shorter survival.

Abstract: introduction: visceral leishmaniasis is a serious public health problem that requires global control strategies, especially with respect to factors that may intervene in reducing the incidence of endemicity. in this work, rainfall density and temperature were correlated with the incidence of human cases in an area endemic for leishmaniasis in s?o luis do maranh?o, northeastern brazil. methods: notification of human cases by the national health foundation/regional coordination of maranh?o (funasa/corema) from 2002 to 2010 was used. ecological data (mean temperature and rainfall density) were provided by the meteorological office of state. results: a significant association was verified between the number of vl cases and rainfall rate but not in the analysis concerning mean temperatures. conclusions: these data suggest that the control actions in visceral leishmaniasis should be performed during rainy season in the state of maranh?o, which is in the first half of the year.

Brazilian Journal of Microbiology , 2002,
Abstract: This work was conducted on rats in two premises located in Niterói and Rio de Janeiro, Brazil. One is classified as conventional controlled and the other, conventional. The objective of the present study was to detect the presence of Mycoplasma pulmonis in animals with symptoms of respiratory disease and low reproductive performance. In the conventional controlled premises, 16 rats of Wistar-Furth strain were necropsied while in the conventional premises necropsy was performed on 12 rats of Hooded Lister strain. The clinical samples of lungs, trachea, oropharynx, middle ear, uterus and ovaries were subjected to culturing while the sera were tested for antibody detection. From 28 rats, 57.14% (16/28) were culture positive for M. pulmonis, being 81.25% (13/16) from the conventional controlled premises, and 25.00% (3/12) from the conventional premises. The ELISA test was carried out in 20 animals of both colonies. In the conventional controlled premises, 92.86% (13/14) were positive for M. pulmonis, and 7.14% (1/14) were suspicious, while in the conventional premises, 100% (6/6) of the samples were positive. The results confirmed that M. pulmonis was the etiologic agent of the disease that affected the rats under study, and that the ELISA positivity rated higher than culture.

Journal of the Brazilian Chemical Society , 2012, DOI: 10.1590/S0103-50532012005000033
Abstract: the lipases cal-b, psl, psl-c, psl-d, and a. niger lipase, free or immobilized in starch (obtained from two types of yam, known in brazil as “cará” (discorea alata l.) and “inhame” (colocasia esculenta (l.) schott) or gelatin films, were used in the acylation of (rs)-sec-butylamine with different acyl donors in various organic solvents applying conventional heating (ch) or microwave (mw) irradiation. in the case of free a. niger lipase, the conversion degrees were three times higher using mw irradiation when compared to conventional heating at 35 oc. using free a. niger lipase, the (r)-amide was obtained with a conversion degree of 21%, resulting in eep > 99% and e-value (enantioselectivity value) > 200, in 1 min of reaction under mw irradiation. when the a. niger lipase was immobilized in yam starch films, the (r)-amide was obtained in moderate conversions of 8-25% after 3 or 5 min of reaction under mw irradiation, but with higher selectivity (eep > 99% and e > 200) in comparison with the free form (conversion degree of 45%, eep 81% and e value of 18).
