Variação temporal da riqueza de táxons, abundância e biomassa de artrópodes em ambiente de restinga do Rio Grande do Norte, Brasil

Arthropods are abundant organisms possess great wealth and diversity representing about 82% of all known animal species. Contribute as a source of biomass and their abundance is an indicator of ecological change. The aim of this study was to evaluate the biomass and abundance found in the salt marsh environment throughout the year and relate them to the climatic factors (temperature, precipitation and relative humidity) that can influence the abundance and biomass of arthropods. The study was conducted at the Centro de Lançamento de Foguetes Barreira do Inferno, city of Parnamirim, Rio Grande do Norte, in the period February 2011 to January 2012, using pitfall traps, stationary window and beating tray. Among the 26 orders found, the most abundant were: Hymenoptera, Orthoptera, Araneae. Taxa Hymenoptera, Blattodea and Orthoptera showed higher biomass volume. Climatic factors did not influence the fall of Arthropods in the traps, however, the lowest abundance during the rainy season the action of raindrops, reduced the activity of these arthropods on vegetation, reducing its capture in traps (pitfall traps and stationary window ) and method of collection(entomological umbrella)

Estratégia reprodutiva do peixe hermafrodita mussum, Synbranchus marmoratus Osteichthyes, Synbranchidae em um açude do Rio Grande do Norte, Brasil

Reproductive strategy of the hermaphrodite fish the marbled swamp eel, Synbranchus marmoratus (Bloch, 1795) (Osteichthyes: Synbranchidae) was investigated in the Marechal Dutra reservoir, Acari, Rio Grande do Norte, using fish samples captured monthly during the period of July 2010 to July 2011. The limnological parameters and rainfall were verified. The captured fish specimens were numbered, weighed, measured, dissected and their gonads and liver were removed, weighed and identified as to sex and developmental stages of gonads. The length-weight relationship was determined for grouped sex. The size of first gonadal maturation, gonadosomatic index (GSI), condition factor (K) and hepatosomatic index (HSI) were calculated. The development stages of the gonads were investigated using macroscopic and histological techniques, besides the fecundity and reproductive period. The macroscopic characteristics and the histological development of gonads confirmed the four different sexual types in the sampled population: primary males, females, intersex and secondary males. The secondary males were bigger and heavier than all the other types. This species showed a negative allometric growth with a higher increase in length than weight. The size at which 50% of the females began the process of gonadal maturation was 43.5 cm of total length, and for secondary males it was 58.5 cm. Condition factor showed two peaks in February and in April 2011. IGS indicated a reproductive period from July to September 2010 and was negatively correlated with the condition factor and rainfall. IGS showed a negative correlation when compared with the condition factor and the rainy season. HSI was highest in February ad lowest in December. The reproductive period of this species occurs between the end of the rainy season and the beginning of the dry season. S. marmoratus presents a seasonal reproductive strategy which optimizes its reproductive success under the semiarid climatic conditions

Uso e disponibilidade da vegetação lenhosa em comunidades rurais no Rio Grande do Norte

The aim of this study was to test the Ecological Apparency Hypothesis comparing two rural communities in João Câmara (RN) and Remigio (PB), in the Northeast of Brazil. This hypothesis assumes that plants are perceived, known and used by human populations according to their local availability. The most used species would be the ones that are more available in the forest (apparent), and apparently suffer greater pressure of use. Communities were consulted through semi-structured interviews. In Remigio 42 people were interviewed, and 50 in João Câmara. The importance of each species was evaluated considering the distinction between citations from current and potential uses. The ethnobotanical information was associated with phytosociological parameters collected by the point-centered quarter method in forested areas, where 50 transects were distributed in each community, and 4,000 individuals sampled in total. Based on the interviews, 58 useful species were recorded, 42 genera and18 families. In the phytosociological study 30 species, 22 genera and 12 families in João Câmara, In Remígio were identified 34 species, 22 genera and nine families.The species were grouped into 11 categories of use. The ecological appearance was confirmed only in the João Câmara, which best explained the relationship between local availability and use of timber resources. Positive correlations were observed also between the technology category VUpotential and dominance. The point-centered quarter was efficient to test appearance, however, further studies through the point-centered quarter method are recommended

Agregação familiar e resultados maternos e perinatais da pré-eclâmpsia severa em população do Rio Grande do Norte

To determine whether there is familiar aggregation of severe preeclampsia in a Brazilian population from Rio Grande do Norte and to characterize the maternal and perinatal outcomes in the studied population. Methods: A case control study was performed with 412 participants who were admitted at Maternidade Escola Januário Cicco (MEJC) for medical care. Of these, 264 subjects presented normal blood pressure and 148 were cases. Cases were composed of eclampsia (n=47), HELLP Syndrome (n=85) and Eclampsia associated with HELLP syndrome (n=16). The diagnosis of these illness were based on the citeria developed by National High Blood Pressure Education Program Working (2000). An interview was performed with each subject and questions related to personal and familiar history of hypertension, preeclampsia, HELLP syndrome and eclampsia. Statistical analysis was performed and comparison of median and mean between cases and controls were performed, with the level of significance of 5%. The Odds-Ratio was determined to estimate the risk of preeclampsia within the families. Results: There were no difference in the demographic data between cases and controls. Previous history of chronic hypertension and preeclampsia was more frequent in the case group. Headaches were more frequent in eclampsia and epigastric pain in the HELLP syndrome cases. Bleeding and oliguria were more frequently found in the eclampsia associated with HELLP syndrome cases. Acute Renal insufficiency was a common complication in the case group, but these cases did not evolve to chronic renal insufficiency. The maternal mortality was 0.4% and the perinatal mortality was high, 223 per 1,000 live births. The 111 risk of a woman to develop preeclampsia whose mother has hypertension or had preeclampsia was respectively 2.5 and 3.5. This risk was increased 5 times, when a sibling has hypertension and 6 times when both sibling and mother had previous history of preeclampsia. Conclusions: This study confirms that there is familiar aggregation of preeclampsia in this Brazilian population. The potential for cardiovascular complications due to development of chronic hypertension indicates the need of closely follow up of women who develop preeclampsia

Determinantes socioeconômicos e ambientais do declínio das hospitalizações por diarréias em lactentes no Rio Grande do Norte - 1992 a 2001

There was a significant decline in hospitalizations for acute diarrhea in children younger than 1 year of age in Brazil between 1992 to 2001. The less economically developed state of Rio Grande do Norte is a case example of the national trend. In this work, we show a significant association between improvements in socioeconomic variables as well as increased access to sanitation and the decreased rate of hospitalization. Additionally, we observed a positive, seasonal correlation between rainfall and hospitalizations. Most notably, however, we show that improvements in income and inflation were positively correlated with a decline in hospitalizations. Improvements in public health infrastructure, socioeconomic variables like education and literacy, and increased investment in health services were important in reducing severe early childhood diarrheas. However, the data suggests that increased buying power and reductions in poverty played an equally crucial role in reducing hospitalizations for acute diarrhea in infants in Brazil. The work includes elements of the demography of the period for the age groups involved, children under one year, women in fertile age and fertility rate

A Humanização e a Formação Médica na Perspectiva dos Estudantes de Medicina da Universidade Federal do Rio Grande do Norte

The aim of this study is to understand the perception of medical students at the Federal University of Rio Grande do Norte (UFRN) about humanization in the context of their medical formation, using a qualitative approach. The focus group and participant observation techniques were used, involving a multidisciplinary team composed of professionals from the areas of anthropology and psychology, as well as professors from the medical course, who studied two groups of nine students in their final year. The data were analyzed using the categorical thematic content analysis technique, from which emerged three categories: student/patient relationship, teaching/learning and student/professor relationship. The first allows us to identify that student-patient contact is an essential experience for adopting a more humanized view of the disease process. The second category shows that unqualified professors in the pedagogic practices inherent to the teaching profession and the theory the practical dichotomy hinder the autonomous and holistic formation of knowledge. Similarly, the lack of practices outside the academic environment and the absence of multiprofessional stimulation interfere in the construction of an integral view of the individual. From the third category, the student/professor relationship, emerge two opposing subcategories (professor model and assymetric relationships), which reflect the importance of the professor`s ethical humanist position, as opposed to an authoritarian attitude, to form the professional attitude of the student. The results point important aspects of the medical formation that may open a discussion about humanization, in the context of new national curricular guidelines

Intervenção dietoterápica em portadores de lipodistrofia generalizada congênita do Rio Grande do Norte

Congenital generalized lipodystrophy is a rare genetic disease with autosomal recessive inheritance characterized by the generalized absence of subcutaneous adipose tissue and insulin resistance. The aim of our study was to determine the profile of patients with congenital generalized lipodystrophy (Berardinelli-Seip syndrome) through their clinical history, eating habits, and socioeconomic and cultural aspects; assess food consumption and nutritional status of the study group; propose and evaluate a diet therapy model associated to oral supplementation with zinc to help in the control and prevention of metabolic complications associated to the pathology. Initial assessment of food consumption indicated a voracious appetite in all the patients studied. The introduction of zinc reduced appetite, contributing to patient adherence to the food plan proposed. It was also observed that the proposed diet contributed mainly to glycidic control, specifically with respect to HbA1c. The nutritional status of the patients investigated was adequate in terms of body mass index (BMI), arm muscle circumference (AMC), arm muscle area AMA, but triceps skinfold (TSF) indicated serious malnutrition. Our study is unique in the literature and provides important information to the field of nutrition and to individuals with this pathology. Furthermore, it contemplates the interdisciplinary and multidisciplinary requirements of the Postgraduate Program in Health Sciences of the Federal University of Rio Grande do Norte (UFRN), Natal, Brazil

Características físicas, somatotipo e desempenho de corredores de 100 e 400 metros no Rio Grande do Norte

Objective: The aim of the study was to investigate physical characteristics and to examine association between somatotype and performance in collegiate runners of 100 m and 400 m. Methods: The sample, male runners (n=39) competing at the regional level in the state of Rio Grande do Norte, Brazil, had height, body mass, skinfolds, limb circumference and skeletal breadths measured. Then, the somatotype was calculated by Health-Carter method. Races (100 m and 400 m) were held to assess athletic performance. Descriptive statistics were calculated for the total sample, as well as for the 100 m and 400 m groups, and established four subgroups, named quartiles. For analysis between groups of runners (100 m x 400 m) was used Student's t test for independent samples. To examine the relationship between the race times and anthropometric variables, was used the Pearson correlation test. The somatotype dispersion distance and somatotype spatial distance were calculated among subgroups. One-way analysis of variance, the Wilcoxon test followed of Tukey post test, and correlation analysis were used with a significance level of p<0.05. Results: Somatotype with mesomorphy and ectomorphy dominance was exhibited by 100 m and 400 m athletes. Endomorphy was low in both groups, especially in 400m runners, who had more elongated body types than 100 m runners. When separately compared by athletic performance quartile, 100 m sprinters of better qualifications (G100-G1) had somatotype with dominant mesomorphy, whereas 400 m runners had somatotype with dominant ectomorphy. A significant correlation (r = -0.55, p=0.008) between calf circumference and 100 m race times was observed showing the importance of muscularity, whereas a significant correlation was found between height and 400 m race times (r = -0.53, p=0.02) showing the importance of linearity. Conclusion: Runners of 100 and 400 may show differences in physical characteristics, depending on the level of athletic performance. Anthropometric periodic evaluations may help in the training process of these athletes. However, more specific assessment parameters should be taken into account, because somatotype by itself has not power to predict whether an individual will succeed in racing speed

Relações trabalhistas e estilo de vida do atleta profissional de futebol do Rio Grande do Norte

Brazilian Law n° 9.615 of 24 March, 1998 established new paradigms in the employment relations existent between the soccer athlete and the sport association, both of whom are accustomed to the former legislation. They do not seem to have organized themselves in the sense of understanding the practical effects of the legal precepts currently in force, raising doubts that hinder the professional practice of the former and the performance of the latter in relation to managing these human resources. The purpose of this study is to analyze the degree of knowledge displayed by the professional soccer athlete about the legal recourses at his disposal in relation to the employment relations established in his work contract, as well as investigating the stress habits and stress situations that he most often experiences. This descriptive study consisted of a sample of 105 players under contract with clubs participating in the final phase of the state soccer championship. A questionnaire was used as the data collection instrument, whose analysis allows us to verify the lack of knowledge, on the part of the subjects studied, about the laws that regulate their profession, as well as identifying the stress habits and stress situations that are most reflected in their lifestyle. The lack of knowedge of regulate norms of their profession influences, in a negative way, in the lifestyle of soccer professional athlete from Rio Grande do Norte, Brasil

Qualidade de vida do servidor da Universidade Federal do Rio Grande do Norte em condição crônica de saúde

The study aimed to analyze the influence of chronic health conditions (CHC) on quality of life (QOL) of UFRN servers assaulted by CHC. It is a descriptive and cross-sectional study with prospective data and quantitative approach, accomplished in the ambulatory clinic of the Department of Server Assistance (DSA) of the Pro-Rectory of Human Resources, during three months. The sample was composed by accessibility, totaling 215 people, being 153 active and 62 inactive servers, in chronic health condition. The data were collected through the application of the sociodemographic characterization, health, environmental and laboral form, the Medical Outcome Study 36-Item Short Form (SF-36). The study was evaluated by the HUOL Ethics Committee (CAAE no. 0046.0.294.000.10), obtaining assent. The results were analyzed in the SPSS 15.0 program through the descriptive and inferential statistics. It was identified servants predominantly male (59,1%), under 60 years old, married or in stable union, Catholics, brown color, living in the capital and residents in own home. Regarding labor issues, there was a predominance of active servers technical-administrative with intermediate and medium level positions and small proportion of docents. Among the CHC, the non-communicable diseases - NCDs (95.8%) had a higher frequency, followed by persistent mental disorders - PMDs (18.6%) and, finally, the continuous and structural physical deficiency - CSPD (16.9 %). The QOL of servers was considered good, with a mean score of 72.5 points in the total score, with the most affected domains: physical (59.1), general health (66.2), bodily pain (66.3) and functional aspects (72.0). The mental health dimension (76.5) had a better average than the physical dimension (68.0 points). It was found that the decrease in QOL scores is significant statistically related to higher number of CHC (ρ <0.001), with no statistical significance regarding the functional situation (p = 0.259). The administrative technicians of elementary, primary, secondary levels and docents had the worst QOL scores. After the correlation analysis of CHC with the domains and dimensions of the SF-36, there was statistically significant, negative and weak correlation of the domains: functional aspect (ρ = 0.002, r = -0.207), physical aspects (ρ = 0.007; r = -0.183), vitality (ρ = 0.002, r = -0.213), social function (ρ = 0.000, r = -0.313), emotional aspects (ρ = 0.000, r = -0.293), mental health (ρ = 0.000 , r = -0.238), physical health dimension (ρ = 0.002, r = -0.210) and mental health dimension (ρ = 0.000, r = -0.298). The presence of PMD isolated or together, contributed to a lower SF-36 scores, being the domains variation of mean significant, except for bodily pain, general health and physical aspects. By correlating the categories of CHC and QOL, there was a weak correlation (r ≤ -0.376) and significant (ρ ≤ 0.011), mainly related to the NCD, PMDs and NCD + PMD, affecting the mental health, social function, emotional aspects, vitality and functional aspect domains. Front of the results, it was concludes that the servers quality of life is influenced by the CHC. Thus, it was inferred that the presence of CHC causes a negative effect on quality of life, leading the active and inactive servers to exposure their overall life activities and work over the years, due to the morbidity affected, mainly related to NCDs and PMDs. Descriptors: Quality of life. Chronic disease. Occupational Health. Nursing

Avaliação dos parâmetros hematológicos e imunofenotípicos de pacientes com doenças linfoproliferativas crônicas no Rio Grande do Norte

Chronic lymphoproliferative disorders (DLPC) are lymphoid system diseases characterized by the abnormal proliferation of mature lymphocytes that affect B cells, T lymphocytes and NK cells. The aim of the study was to demonstrate the relevance of immunophenotyping by flow cytometry in patients with prolonged lymphocytosis and / or cytomorphological changes compatible with lymphoproliferative diseases. In this study 460 patients (244 men and 216 women) with DLPC were evaluated. Were analyzed by flow cytometry with a panel of monoclonal antibodies consisting of CD3, CD4, CD5, CD8, CD10, CD19, CD22, CD23, CD25, CD38, CD45, CD16/CD56, and HLADR heavy and light chains of immunoglobulins. It also examines information regarding age, gender of patients and laboratory data as leucocytes, cytomorphological analysis, platelet count and hemoglobin determination. The results showed 398 cases of chronic lymphoproliferative disorders and 62 of DLPC B cell lymphoproliferative diseases T. B showed the following distribution : 253 cases of chronic lymphocytic leukemia (CLL), 42 cases of multiple myeloma ( MM ), 37 cases of lymphoma non - Hodgkin lymphoma in leukemic phase (NHL) , 17 cases of pro- B lymphocytic leukemia ( B -PLL), 15 cases of mantle cell lymphoma (MCL ), 12 cases of plasma cell leukemia ( PCL), 9 cases of lymphoma Burkitt (Linf B), 8 cases of leukemia villous cells ( LCV), 3 cases of splenic lymphoma with villous cells (LECV), a case of follicular lymphoma (LF) and a Waldenströn macroglobulinemia ( MW). The diseases source NK / T were 23 cases of peripheral T cell lymphoma (LCTP), 14 cases of T prolymphocytic leukemia (T -PLL), 10 cases of leukemia T of large granular lymphocytes (LGL -T) 9 cases of leukemia cells of adult T (LCTA), 5 cases of Sezary syndrome (SS) and a case of large granular NK leukemia (LGL -NK) lymphocytes. In conclusion, the combined use of the monoclonal antibody panel careful cytomorphological analysis was shown to be essential in immune diagnosis and classification of chronic lymphoproliferative disorders. This study was approved by the IRB - HUOL under number 356 / 09

Fisioterapia e sociedade: ações do Sistema Único de Saúde no Rio Grande do Norte

The work has objective to present actions of Physiotherapy, developed by SUS in the State of Rio Grande do Norte; discuss under the humanization point of view such actions of health; discuss the importance of physioterapy to the Norte-Riograndense, or maybe its role in the perpetuation of actions of health centered in the binomial cause/efect. The study was done in the State of Rio Grande do Norte. The data were obtained through public sources gathered in the health secretrary ship of this State. The collected data talks about physiotherapy sections developed by SUS in several areas of the State; such data was collected and analysed after the aproval of Ethic and Resarch Committee of Federal University of Rio Grande do Norte. Concerning the physiotherapy, along with the State Health Secretaryship of the State fo Rio Grande do Norte, there were only records of attending based on cure/rehabillitation, not being observed during the curse of study, any record or action of prevention, promotion and protection towards health. It s possible to notice that there is a highligth to the interventions focusing on the treatment of illness of rheumatic origin and general complaints related to the vertebral column. Such research evidenced that the Physiotherapy in the SUS in the State priorizes the individualized attending centered in the carteziano health/illness model, where the developde actions are turned to the curative and rehabilliting attention, with role fo some or no highligth in the primary attention

Alcoolemia em vítimas fatais de acidentes de trânsito no Rio Grande do Norte empregando cromatografia em fase gasosa - head space

Alcohol is one of the few psychotropic drugs that their consumption has admitted legally and sometimes encouraged by the society. Studies show alcohol as the highest consumption of drugs among young people and society in general, probably because of its availability and easy access. The abuse causes public health problems, which was closely related to the violence, socioeconomic problems and the high number of automobile accidents. Transit is one of the main sectors affected by the effects of alcohol, observing a high incidence in the studies. About half of automobile accidents occurs after the consumption of alcoholic beverage, and the vast majority of cases related to high concentrations of alcohol in the bloodstream. The relationship of drunk with traffic accidents is in fact evident everywhere in the world, including Brazil, where studies have shown a high relationship between alcohol consumption and traffic accidents. This study determined the alcohol in fatal victims of traffic accidents in the state of Rio Grande do Norte and established the profile of this population compared with those found in Brazil and other countries. Samples of blood of ethanol added to fulfillment of the standardization of chromatographic conditions and procedures for the analysis, being employed in the determination of alcohol in blood samples of 277 victims of traffic accidents, collected at the Institute of Scientific Technical Police of Rio Grande do North (ITEP) in the year 2007. The blood alcohol level was determined in these samples correlated with the sex, age and marital status of the victim and the location, day of week and month when the accident occurred, is doing a statistical analysis and outlining a profile of the victims of an accident at transit in the state of Rio Grande do Norte. The parameters of standardization studied ensured the quality of the analytical method and, consequently, to obtain reliable laboratory results. Being given the best temperature for injector (150 ºC), detector (250 ºC) and column (50 ºC) with a flow of gas in the column of 2mL/minutos and analysis of time of 12 minutes. The method was linear in the range of 0.01 to 3.2 g / L (r2 = 0.9989) with average recovery of 100.2% and precision with coefficient of variation less than 15%. The analysis carried out on victims of fatal road traffic accidents, ethanol detected in the blood in 66.43% of the victims and these, 96% showed concentration ≥ 0.2 g / L, 87.73% of victims were male, while 12.27% female. The younger age group (1535 years) was the most involved (52,35%) and most single (55.60%). The accidents occurred with greater prevalence in the day on Monday (27%) followed by Sunday (24,19%) and Saturday (15,52%) and it was found that the prevalence of injuries varied between the different months of the year, and in February (14.4%) and April (10.47%) the months that had a higher number of accidents, however this oscillation showed no statistically significant difference. Also no significant difference was observed between the tracks of concentration found in men and women. The standardized method showed to be efficient, given satisfactorily to the goals of this work, and the high levels of alcohol found in victims of fatal road traffic accidents are consistent with several studies of literature, and the profile of the victim also supported by presenting in its most young adults, male and single

FERRITINA: intervalos de referência para adultos no Estado do Rio Grande do Norte

Ferritin is a protein composed of heavy and light chains, non-covalently linked and which accommodates, in its core, thousands of atoms of iron. Furthermore, this protein represents the stock of iron in the body and it is characterized as an acute marker and predictor of diseases, such as iron deficiency anemia, hereditary hemochromatosis and others. Considering the variability of reference values and the analytical methods currently available, the aim of this work was to propose 95% confidence intervals for adults in the State of Rio Grande do Norte, Brazil, after determining the average concentration of serum ferritin for both sexes, beyond its correlation with the age. We analyzed 385 blood samples, collected by venipuncture from individuals residing in the State, after 12-14 hours of fast. The populational sample had 169 men and 216 women between 18-59 years old, which filled a questionnaire on socioeconomic, food habits and accounts about previous and current diseases. The sample collections were itinerant and the results of erythrogram, fasting glucose, alanine aminotransferase, aspartate aminotransferase, γ-glutamyl transferase, urea, creatinine, leukocyte count and platelets, beyond C-reactive protein, were issued to each participant, so that, after selection of the apparently healthy individuals, the dosage of serum ferritin was carried out. Statistical analysis was performed using the softwares SPSS 11.0 Windows version, Epi Info 3.3.2 and Graf instant pad (version 3.02), and the random population sample was single (finite population), for which the test of linear correlation and diagram of dispersion were also made. After selection of individuals and determination of serum ferritin, the most discrepant outliers were disregarded (N = 358, Men = 154/Women = 207) and the average value determined for the masculine sex individuals was 167,18 ng / dL; for the feminine sex individuals, the average value obtained was 81,55 ng / dL. Moreover, we found that 25% of men had values < 90,30 ng / dL; 50% ≤ 156,25 ng / dL and 75% ≤ 229,00 ng / dL. In the group of women, 25% had values < 38,80 ng / dL; 50% ≤ 65,00 ng / dL and 75% ≤ 119,00 ng / dL. Through the correlation coefficient (r = 0,23 with p = 0,003), it is possible to suggest the existence of positive linear correlation between age and serum ferritin for men. The correlation coefficient for women (r = 0,16 with p = 0,025) also confirms the existence of positive linear correlation between serum ferritin and age. Considering the analysis carried out and specific methods corroborating with the proposed benchmarks, we concluded that the average value found for men is higher than that found for women. Furthermore, this scenario rises with age for both sexes, and the 95% confidence intervals obtained were 74 ng/dL ≤ μ ≤ 89 ng/dL and 152ng/dL ≤ μ ≤183ng/dL for the feminine and masculine sex individuals respectively

Estudo dos fatores associados à infecção chagásica em área endêmica do Rio Grande do Norte

The Chagas disease is a infectious and parasite disease that has as the causative agent a Trypanosoma cruzi, a protozoan parasite that can be transmitted to humans by the faeces of triatomines ( barbeiros ) in the blood-sucking. To understand the relationship between factors associated with chagasic infection and the risk of transmission of Trypanosoma cruzi, this work aimed to make a correlation between the results of serology, obtained by different immunological techniques, used for diagnosis of Chagas disease and risk factors to which the population of the city of Apodi-RN is exposed, to be considered a endemic area. The case-control study was conducted with 199 individuals, which initially was applied a questionary about socio-economic questions and some risk factors which they were exposed and also favor the spread of disease. Then was given the diagnosis by immunological techniques of serology by indirect hemagglutination, ELISA and indirect immunofluorescence. From the diagnosis, the subjects were divided into case group (presence of infection) and control group (no infection). Regarding the descriptive characteristics of the sample, were found a higher frequency of female individuals (59.3%), between 36 and 50 years of age (36.7%), with low education level (91%) and income monthly up to 1 minimum wage (67.8%). The serology, performed by three techniques of different principles, had a reactivity of 38.9% by Indirect Hemagglutination, 39.7% by ELISA and 38.7% by Indirect Immunofluorescence. As the result of the serology, 71 of samples showed reactivity in 2 or more techniques. On some risk variables, was found a significant relationship between individuals who had been bitten by the triatomines and had positive serology for Chagas disease (93.3%). Other variables of risk revealed individuals who had positive serology and had domestic animal (80.3%), lived in poorly maintained homes (97.2%) and near the forest (84.5%). A better understanding of the dynamics of transmission of T. cruzi and the risk factors that contribute to its occurrence in a region are needed to develop effective strategies for control of Chagas disease in these áreas
