Fonseca, Amanda Luiza;Silva, Reysla Andrade;Fux, Blima;Madureira, Ana Paula;Sousa, Fabrizio Furtado de;Margonari, Carina;
Revista da Sociedade Brasileira de Medicina Tropical , 2012, DOI: 10.1590/S0037-86822012000300015
Abstract: introduction: the aim of the present study was to analyze the exposure to risk factors for toxoplasmosis disease and the level of knowledge in pregnant women who were treated by the public health care system (sus) from october 2007 to september 2008 in divinópolis city, brazil. methods: we analyzed 2,136 prenatal exams of pregnant women that were treated from october 2007 to september 2008. results: out of the 2,136 pregnant women evaluated, 200 answered a quantitative questionnaire; 49.5% were seropositive for immunoglobulin (ig) g and 3.6% for igm. comparative analysis of congenital toxoplasmosis cases were evaluated in 11 regions and showed an irregular distribution (p < 0.01). this difference was also observed among the pregnant women observed in each location. the results from the questionnaire show that 93% of the pregnant women had no knowledge about toxoplasmosis, and 24% presented with positive serology, but no clinical manifestation. analysis for pregnant igg-positive women and the presence of pets showed a statistically significant correlation (p < 0.05), suggesting that the transmission of this disease might occur in the domestic environment. conclusions: we suggest the implementation of a triage program for pregnant women and health education to encourage their use of sus services.

Abstract: Background. Leishmaniases are diseases with a wide spectrum of clinical manifestations including cutaneous (CL) and visceral (VL) forms. Many factors may affect their occurrence and expansion including environmental, geographic, and social conditions. In the past two decades, Divinópolis, Minas Gerais State, Brazil, has exhibited the potential for a disease outbreak, with the appearance of CL, and VL cases (human and canine). Hence, this study was initiated to monitor public knowledge of the disease. Questionnaires were administered in four neighborhoods (Jardim Belvedere, Esplanada, Danilo Passos I and II) where most of the human and canine cases have been reported. The analyses demonstrated that public knowledge of the disease is sparse and fragmented. A strong perception of the dog as the main reservoir was observed. Five veterinary clinics were evaluated for the presence of canine VL using serological (RIFI and ELISA) and molecular (PCR-RFLP) techniques. This is the first study demonstrating the occurrence of Leishmania infantum in Divinópolis, suggesting a possible urbanization of VL. 1. Introduction Leishmaniases are a group of diseases caused by the protozoan Leishmania (Kinetoplastida: Trypanosomatidae) affecting 12 million people in 88 countries. The disease exhibits a wide spectrum of clinical manifestations ranging from benign cutaneous lesions (CL) to the fatal visceral form (VL) [1]. In Latin America, especially Brazil, both forms are widely distributed and are transmitted by the bite of phlebotomine sand flies (Diptera: Psychodidae) [2]. Wild and domestic reservoirs including foxes, marsupials, rodents, dogs, and cats are the main sources of sand fly infection [3–8]. Many factors may have contributed to VL and CL expansion and urbanization [9], including deforestation [10], human migration [11], vector adaptation [12, 13], drug resistance [14], poverty [15], and social conflicts [16]. As a result of anthropic modifications, VL has been increasingly reported in urban areas of major Brazilian cities including Natal, Teresina, Sobral, and Belo Horizonte [5, 17–20]. The city of Divinópolis, Minas Gerais State, Brazil, has a population of approximately 210,000. It has grown dramatically, with 90.5% of its territory completely urbanized in 2000 [21]. During the 1990s, 135 CL cases were detected by health authorities. Most of those cases were reported in the neighborhoods of Jardim Belvedere, Esplanada, S?o José, Catal?o, and Candelária, all in the vicinity of Mata do Noé forest, where a large area was deforested. More recently, another forest

Abstract: We present numerical studies on the switching characteristics of a fiber Bragg grating (FBG) with modulation in the third order nonlinear index of refraction along it’s length. The FBG is operating in a continuous wave regime (CW). This study was done taking into account the possible asymmetry brought by the non harmonic modulation of the nonlinearity, leading to different reflection and transmission characteristics, that depend on the direction of propagation along the modulated nonlinear FBG. This phenomenon may be useful for applications like an optical isolator. It was found that for a set of values of the modulation parameter, the FBG can exhibit multistable states. The numerical studies were obtained starting from the coupled-mode equations solved from the coupled-mode theory and simulated using the fourth-order Runge-Kutta method.

Abstract: Background: Investigating self-perception of oral health among the elderly may contribute towards changing public health and assistance policies in the area. Methods: The present study assessed the oral health status (tooth decay, need for treatment, periodontal status, use of and need for dental prosthesis, soft tissue alterations and self-perception of oral health) of 102 elderly people from two community groups in Fortaleza, Ceará State, Brazil. Results: Mean age was 69.9 years and 82.4% were female. Mean DMFT was 30.17 with a predominant missing component; 63.7% were edentulous. Regarding prosthesis, 29.4% and 67.6% of elderly patients did not use upper and lower dentures respectively, while 66.7% and 78.4% required some type of upper and lower prosthesis respectively. Among valid sextants, 44.3% presented dental calculus and 34.3% presented loss of attachment from 6 to 8 mm. Soft tissue alterations were found in 58.8%. Despite of precarious clinical conditions and dental treatment needs, good oral health perception was found (49%), as well as satisfaction with the appearance of teeth and gums (60.8%). Conclusion: Subjects displayed unsatisfactory oral health conditions, accumulated over time and resulting from the lack of policies favoring this age group. There is a need for oral rehabilitation that enables the recovery of function and esthetics among the elderly, restoring their self-esteem and improving social interaction.

Abstract: Objective: To conduct the translation to Portuguese and the cross-cultural adaptation to Brazilian culture of a questionnaire to evaluate the aesthetic concerns of 12-yr-old children and their parents. Methods: The original questionnaire, which investigates the level of the child′s distress, worry, and smile avoidance in the last two months, was not validated to any other languages but the ones it was originally developed for (English and Spanish). This report had the following design: translation, back-translation, validation by a panel of experts and testing of the final version with 50 pairs of parents/children, using self-report or interview. Results: No relevant discrepancy amongst versions was found; only minor adjustments were made to adapt the questionnaire to the target population′s diverse educational background, and no item from the original questionnaire has been removed. Simple vocabulary and short phrases were used in order to facilitate the application to children and adults in a location in the Northeast and another in Southeastern Brazil. In the pre-testing, Brazilians easily understood the questions. When the questionnaire was self-applied, there was difficult in reading by children, non-response from parents and unanswered items by both groups. Conclusion: The Child’s and Parent’s Questionnaire about Teeth Appearance was adequately translated into Brazilian Portuguese and adapted to the cultural context of both locations, and it is suggested using it as an interview.

Abstract: multivariate techniques were used to evaluate the genetic divergence among genotypes of common bean, aiming to identify segregating populations with large genetic variability. the multivariate techniques used were: the average euclidean distance based on standardized variables (de), on scores of the three first canonical variables (dvc), on scores of the first three principal components (dcp), on the first three factor loads (dft), and the mahalanobis generalized distance (d2). twelve common bean genotypes were used (aporé, h-4-7, pf-9029975, ci-128, carioca mg, ci-21, carioca 300v, ouro negro, a-285 rudá, esal 693, pérola e iac carioca aru?), and evaluated in four seasons (jul-nov/97, nov/97-feb/98, feb-jun/98 and jul-nov/98), based on ten morpho-agronomic traits. a randomized block design with three replications was utilized. the multivariate techniques showed similar results mainly for identifing the more divergent genotypes. among them, esal 693 and ouro negro were genetically different between themselves and among the other genotypes. pf-9029975 and carioca mg were genetically similar, although different of other genotypes according to average euclidean procedures. it should be pointed out that aporé genotype was divergent of pérola genotype, although the last one is a selected line in the aporé. therefore, all of those genetically divergent genotypes are promissing to cross for obtaining higher segregating populations, specially esal 693 with the others that have a carioca grain type. a resonable correspondence was found in the identification of traits with smallest contribution to genetic diversity.
