Abstract: objectives: to determine the reasons for diagnosis of anemia among children and referral to specialized services. methods: an historical and concurrent cohort study was carried out among anemic children referred to the hematology service of the federal university of minas gerais's clinical hospital, belo horizonte, in the state of minas gerais, brazil, between may 1999 and december 2001. results: 153 children aged under 16 were evalua-ted, 83% of whom had been referred by health centers. approximately one third of the children did not receive any treatment at the referring service. one hundred and eleven (71.3%) were diagnosed as having iron-deficiency anemia. thirteen children (8.6%) received a diagnosis of thalassemia minor; and a further thirteen other anemia-related diagnoses. 11.5% had no kind of anemia. the mean hemoglobin levels were significantly higher when tested by a hematologist than at the referring services (9.7±1.9 vs. 8.9±2.0); p=0.001. only 16.2% of children did not respond to initial treatment with oral iron salts, with iron (ii) sulfate being the medication usually prescribed (79.3%). conclusions: iron deficiency was the main cause of children being referred to a specialized service for reason of anemia. unnecessary referral of individuals with iron-deficiency anemia is potentially harmful to patients and puts an excessive burden on the health system.

Abstract: American cutaneous leishmaniasis (ACL) is a focal disease whose surveillance and control require complex actions. The present study aimed to apply integrated tools related to entomological surveillance, environmental management, and health education practices in an ACL-endemic area in Rio de Janeiro city, RJ, Brazil. The distribution of the disease, the particular characteristics of the localities, and entomological data were used as additional information about ACL determinants. Environmental management actions were evaluated after health education practices. The frequency of ACL vectors Lutzomyia (N.) intermedia and L. migonei inside and outside houses varied according to environment characteristics, probably influenced by the way of life of the popular groups. In this kind of situation environmental management and community mobilization become essential, as they help both specialists and residents create strategies that can interfere in the dynamics of vector’s population and the contact between man and vectors. 1. Introduction American cutaneous leishmaniasis (ACL) is among the six most important infectious diseases and the 15 most neglected diseases of the world [1]. It presents a diversity of transmission cycles that involve different species of parasites, vectors, and hosts in restricted ecological niches [2]. Thus, the indication of control measures must consider the entomological and epidemiological characteristics of each locality. According to Sabroza et al. [3], for each disease and particular situation there are environmental and behavioral factors related to the production of endemic or epidemic processes. To explain these factors, Sabroza et al. [3, page 216] used the concept of conditions receptivity, defined as the “set of environmental, social and behavioral characteristics that allow the reproduction of the parasites and its maintenance in the communities.” The city of Rio de Janeiro presents many areas where these conditions are met, mainly because of human occupation of hillsides, which modifies the landscape and favors the installation of ACL transmission cycles. The number of cases in the city has been increasing since the 1980s, with the west zone presenting the highest indices, more specifically the region of Jacarepaguá [4]. Most of the cases in the study area (Campus FIOCRUZ da Mata Atlantica - CFMA, Rio de Janeiro) are related to the occupation of hillsides in Maci?o da Pedra Branca, an Atlantic Forest area. The present study aimed to discuss an experience on ACL surveillance based on integrated tools related to entomological

Abstract: Low-level laser therapy (LLLT) has been used as an anti-inflammatory treatment in several disease conditions, even when inflammation is a secondary consequence, such as in myocardial infarction (MI). However, the mechanism by which LLLT is able to protect the remaining myocardium remains unclear. The present study tested the hypothesis that LLLT reduces inflammation after acute MI in female rats and ameliorates cardiac function. The potential participation of the Renin-Angiotensin System (RAS) and Kallikrein-Kinin System (KKS) vasoactive peptides was also evaluated. LLLT treatment effectively reduced MI size, attenuated the systolic dysfunction after MI, and decreased the myocardial mRNA expression of interleukin-1 beta and interleukin-6 in comparison to the non-irradiated rat tissue. In addition, LLLT treatment increased protein and mRNA levels of the Mas receptor, the mRNA expression of kinin B2 receptors and the circulating levels of plasma kallikrein compared to non-treated post-MI rats. On the other hand, the kinin B1 receptor mRNA expression decreased after LLLT. No significant changes were found in the expression of vascular endothelial growth factor (VEGF) in the myocardial remote area between laser-irradiated and non-irradiated post-MI rats. Capillaries density also remained similar between these two experimental groups. The mRNA expression of the inducible nitric oxide synthase (iNOS) was increased three days after MI, however, this effect was blunted by LLLT. Moreover, endothelial NOS mRNA content increased after LLLT. Plasma nitric oxide metabolites (NOx) concentration was increased three days after MI in non-treated rats and increased even further by LLLT treatment. Our data suggest that LLLT diminishes the acute inflammation in the myocardium, reduces infarct size and attenuates left ventricle dysfunction post-MI and increases vasoactive peptides expression and nitric oxide (NO) generation.
índice de desempenho competitivo das empresas de polpa de frutas do Estado do Pará

Abstract: the objective of this paper was to construct a competitive performance index (cpi) for the fruit?s pulp firms of state of pará. a factor analysis and multiple regression models were used to estimate the cpi. out the 27 firms analyzed, the results showed that only one firm presented a high cpi and three firms are obtaining intermediate cpi. finally, there is a positive relationship between the firms? cpi and the variables profit?s margins and number of supplier was observed.

Abstract: purpose: to establish a normality curve of cervical length during pregnancy measured by transvaginal ultrasonography. methods: we conducted a prospective, longitudinal study on 82 healthy pregnant women who were followed up from the beginning of pregnancy to delivery at four-week intervals, of whom 49 concluded the study. patients were divided according to parity into nulliparous women and women with one or more previous deliveries. cervical length was measured in a sagittal view by transvaginal ultrasonography, as the linear distance between internal and external cervical os. results: no significant difference was observed in mean cervical length or the 5th, 25, 50th, 75th, or 95th percentile according to gestational age between groups (p>0.05). between the 20th and 24th gestacional week, the 5th, 50th and 95th percentiles of cervical length were 28, 35 and 47.2 mm, respectively. cervical length decreased progressively during normal pregnancy, with a significant shortening observed after 20 weeks of gestation and being more marked after 28 weeks (p<0.05). conclusion: the pattern of cervical length behavior does not seem to differ between nulliparous women and women with one or more previous deliveries. the numerical values of the normality curve of cervical length according to gestational age reflect the variability in the peculiar characteristics of the studied sample, thus emphasizing the value of the parameters established for different populations.
