Prevalência e determinantes de oclusopatias nas dentições decídua, mista e permanente na cidade do Natal/RN

This work is intended to bring a contribuition to the verification of the prevalance of malocclusion in the deciduous, permanent and mixed dentition in the student population in the city of Natal, Brazil. In this purpose, a sectional study of infantiles aging 5, 8 and 12 years old was carried out. The average prevalance of malocclusions in the group as a whole was 76,5%. Considering the different dentitions separately, the study showed malocclusion prevalence as follows: Deciduous Dentition 75,5%; Mixed Dentition 84% and Permanent Dentition 70,5%. The most common malocclusion cases found in the deciduous dentition were openbite (20.6%); overbite (16.6%) and maxillary overjet (14,7). Mixed Dentition: the most commonly found occlusional malfunctions in this dentitional phase were maxillary overjet (33,8%); crowding (28,3%), and mandillary discrepancy (19,9%). In the univaried analysis, he application of the Chi square test of independence, (significance 5%), has indicated a meaningful association of the variables social class (p=0,019), primata space (p = 0,036), habits (p= 0,002) and time-and-habit (P=0,03). The same test on the permanent dentition group revealed a significant association for the independent variables, as follows: Social class (p=O,OOO), School (p=O,OOI), Income (p=O,OOO), housing standard (p=0,001), facial pattem (p=0,004), caries record (p=0,031). No significant association was found in the mixed dentition. The Logistic Regression analysis on the deciduous dentition has shown that income, ethnicity, habit and canine relationship constitute factors of risk regardless of the other variables. As for the permanent dentition, only Facial Pattem was pointed as a factor of risk for the formation of malocclusion

Estudo clínico e níveis de ansiedade em uma série de casos de líquen plano oral

Oral Lichen Planus (OLP) is a relatively common, cronic inflammatory disease. Its etiopathogenesis is no completely understood and several factors have proposed in attempt to explain the appearance, variety of clinical manifestations and periods of exacerbation and remission of the symptons of the lesions. The objective of the present study was to assess the presence of local factors, systemic diseases and levels of anxiety in patients with OLP, investigating their association with the clinical characteristics of the lesions. The sample consisted of 37 patients with histopathologically confirmed OLP that were submitted to a clinical exam to evaluate the presence of smoking habits, consumption of alcoholic beverages, diabetes mellitus, hypertension and hepatitis C virus (HCV) infection. The existence of skin lesions, as well as the time course, clinical form, symptomatology, number and location of the oral lesions were also registered. The trait anxiety was measured by Spielberger s Stai-Trait Anxiety Inventory (STAI), and to associate the variables we used the chi-square or Fisher s exact test. It was observed that females were the most affected (75%) and the mean age of the patients was 53,3 years. Most cases were non-smoker (97,3%) and none was drinker. Diabetes mellitus and hypertension were present in 10,8% e 16,2% of the sample, respectively and only one patient was HCV-seropositive (2,7%). Moderate levels of anxiety were seen in most cases (78,4%) and 21,6% had elevated levels. The oral lesions persisted in 95% of the cases for a period of 6 months to 13 years. The erosive form was the most prevalent (57,1%) and symptons were reported by 45,7% of the patients. Multiple lesions were frequent (60%), affecting mainly the buccal mucosa, followed by gums e tongue. There was no significant association of the presence of diabetes mellitus, hypertension and levels of anxiety with the clinical form or symptomatology of the oral lesions (p>0,005), despite a trend in patients with hypertension to have erosive lesions. It was concluded that, in the sample studied, moderate levels of anxiety were commonly observed, and the HCV infection apparently is not related to the onset of the OLP. In this study, the presence of diabetes mellitus, hypertension and levels of anxiety seem not to be associated with the clinical characteristics of the lesions of OLP

Avaliação da expressão imuno-histoquímica de marcadores de hipóxia em carcinoma epidermóide de língua

The tumor hypoxia modulates a series of genetic changes related to adaptive development, invasion and metastasis of various human cancers, among which squamous cell carcinoma of the tongue (SCCT). The objective of this study was to analyze clinical, morphological and immunohistochemical expression by HIF-1α, GLUT-1 and CA-IX in 57 cases of CEL and correlated this expression to clinical parameters and morphological. After a descriptive analysis of data on gender, age, race, and habits of patients, it was found that the results were consistent with the literature. The clinical and morphological parameters analyzed and the expression of these markers of hypoxia were subjected to statistical analysis (Qui2 test), verifying that they can be used as indicators of the biological behavior of CEL. Among the results of this study, we observed that the intensity of expression for HIF-1α, in most cases located in the cytoplasm and nucleus, statistically correlated with clinical staging (p = 0.011) and histological grading (p = 0.002). As for the relationship between the distribution of labeling for HIF-1α and metastasis, the chi-square (Qui2) showed that there was statistically significant differences between the groups (p = 0.040). 75.8% of the sample who had metastases, there was the predominance of diffuse marking. The immunoexpression cytoplasmic/membrane GLUT-1 showed a statistically significant correlation with the clinical stage (p = 0.002) and histological grading (p = 0.000). Concerning the location of markings for GLUT-1 tumor on the island, there was a predominance of peripheral marking specimens in most low-grade (78.6%). In the sample of high-grade, prevailed the location center/periphery (55.8%). According to the chi-square (Qui2), the location on the island of the tumor (p = 0.025) showed statistically significant difference in histological grading. The immunoreactivity of CA-IX, in most cases located in the membrane and cytoplasm, exhibited a statistically significant correlation with histological grading (p = 0.005). Based on these results, we can conclude a broad participation of these markers of hypoxia in oral carcinogenesis and its possible use as markers of biological behavior and tumor progression in CEL

Características sociodemográficas, hábitos de sono, estado cognitivo e funcional após acidente vascular cerebral

ABSTRACT Introduction: The cerebrovascular accident (CVA) is an important cause of neurological impairment. Few data about the factors associated with morbidity of cerebrovascular accident are found in Brazil. Objectives: Evaluate sociodemographic characteristics, sleep habits, cognitive and functional status of patients with cerebrovascular accident. Methods: The patients evaluated through questionnaire Step 1 to survey the sociodemographic characteristics and Modified Rankin Scale for functional assessment. The neurological degree was evaluated by the National Institutes of Health Stroke Scale (NIHSS), the sleep Habits questionnaire for sleep and cognitive status by the Mini-Examination of the Mental State (MEMS). The data were analyzed using the chi-square test to determine differences in proportions of variables and linear regression analysis. Results: 305 patients were evaluated and the larger number of subjects was between 50 and 69 years (40%), most patients had no formal education (40.3%) and had ischemic type of cerebrovascular accident (72.5%). In the analysis of the functionality it was found that most patients had moderate impairment (55.1%). The results of the sleep habits showed that 63,6% of patients had one more person in the bedroom,12,3% complained about too much noise in the 11 room and 35% of too much light. From these patients 5,8% were smokers, 7,8% and 70,1% drank coffee drinkers, 28,6% had difficulty in initiate to sleep and woke up 37,6% in the middle of the night. Were showed complaints about nightmares (11%), feeling of suffocation (37,7%) and 35% felt very sleepy during the day. In addition, 95% were unemployed, 80,5% did not perform physical activities and 95,4% did not perform mental activities. The cognitive screening conducted a determined association of cognitive status with age and education level and neurological status. Conclusion: The study showed a high frequency of cases of cerebrovascular accident with functional dependence in a moderate degree, identified that many patients do not follow hygienic measures of sleep and found that the assessment of cognitive deficits must take into consideration the age, educational level and degree of neurological patients. We suggest the need for programs of assistance to victims of cerebrovascular accident patients, with a multidimensional approach including the rehabilitation team, the role of sleep medicine and Neuropsychology, so that patients have access to a more appropriate functional rehabilitation, develop a lifestyle that ensures a good sleep quality and are evaluated and rehabilitated with regard to cognitive impairment

Tontura em idosos institucionalizados da cidade do NATAL/RN: Um estudo caso-controle em vestibulopatas e não-vestibulopatas

the institutionalized elderly presents for being more fragile a lot of body balance s changes, which can induce falls and health frailty. One of the consequences of it is the appearance of dizziness, vestibular or not. This study aims to identify the risk factors related to dizziness in institutionalized elderly, with and without vestibular disorders, in the city of Natal-RN. Method: a case-control study realized in 12 regulated by Health Surveillance Long Term Care Institutions for the elderly in Natal-RN. Elected seniors with good cognitive level and able to walk, totaling 115 individuals, and of these, 102 were selected according to the presence of dizziness in the last year (n = 51) and their controls (n = 51), paired by sex and age. The 51 elderly patients with dizziness were divided into 3 groups case: case one, for elderly with dizziness and without vestibulopathy (n=38); case two, for elderly with dizziness and vestibulopathy (n=13) and case three, for all the seniors with dizziness, or added to the case 1 case 2 (n=51). The 51 seniors who served as controls were also divided into three groups, according to the number of individuals of each case: control 1, n = 38, control 2, n = 13 control and 3 (sum of 1 control with control 2), n = 51. As possible risk factors were analyzed variables related to characteristics of the institution, to the habits of life of older people and those concerned with the health of the elderly. For statistical analysis, we used the chi-square or Fisher exact test for a significance level of 5% and calculating the association magnitude between variables by measuring the Odds Ratio. Results: as risk factors for dizziness without vestibular disorders were found the presence of hypertension and cardiovascular disease, as well as the presence of three or more disorders for elderly and use of gastric protector drugs. For the elderly group from case two were found no associated risk factor. For elderly patients with dizziness in the case group three, we observed the same risk factors found for the elderly in the case group one, plus the presence of osteoarthritis pathology, which was also significant for this group. Conclusion: dizziness in institutionalized elderly is associated with systemic common diseases in this age group and the vestibulopathy presents itself as pathology on an isolated way, not being possible, with our data, associate it with non-risk factors

Prevalência da disfunção temporomandibular em estudantes de odontologia por meio de diferentes índices

The epidemiology of temporomandibular disorders varies widely in the literature. The aim of this study was to determine the prevalence of TMD in dental students of the Federal University of Rio Grande do Norte assessed by different indexes. The sample consisted of 101 individuals selected by a randomized process, whose general outline was systematic sampling. For evaluation of the signs and symptoms of TMD, an anamnestic index, Fonseca s protocol, and two clinical indexes, the RDC/TMD (Research Diagnostic Criteria for Temporomandibular Disorders), or standard index, and the Helkimo s Clinical Dysfunction Index were applied. Data were analyzed using the chi-square test and kappa, besides verifying the sensitivity and specificity (5% significance). The diagnosis of TMD by different indexes showed a variation in the prevalence between 72.3% (Helkimo s Clinical index), 64.4% (Fonseca s anamnestic index) and 35.6% (RDC/TMD). There was no statistical difference between the sexes for the RDC/TMD, although this difference was found for Fonseca s and Helkimo s indexes (p<0.05). The most frequent type of TMD were joint disorders (Groups II and III), and the subtypes disc displacement with reduction (17.8%) and arthralgia (15.8%). Most individuals showed a mild TMD (45.5%) for both indexes, Fonseca and Helkimo. When comparing the types of diagnoses, RDC/TMD with Fonseca and Helkimo, low agreement was found (k=0.17 and k= 0.35, respectively). A moderate correlation between the severity of TMD was obtained (kw= 0.53) for Fonseca s protocol and Helkimo s index. High sensitivity and low specificity were seen for both diagnoses compared to standard, resulting in excessive false positives. Within the limitations of the study, it was concluded that the prevalence of TMD can vary widely, depending on the index used for its diagnosis

Influência das condições de saúde bucal no desempenho das atividades diárias de adolescentes escolares

Instruments are used in odontology to measure the Quality of Life Related to Oral Health (OHRQoL) to scale how the oral condition interferes with functional areas, of the people s psychological and social life. This cross-sectional study, held in Natal/RN, with 215 students from the Federal Institute of Education, Science and Technology of Rio Grande do Norte (IFRN) has investigated the association between the performance of daily activities and oral health status of school adolescents from 15 to 19 years of age, through the normative index DMFT (permanent teeth decayed, missing and filled), CPI (Community Periodontal Index) and DAI (dental Aesthetic Index) and subjective questionnaire assessment of quality of life related oral health OIDP index (oral impacts on daily performance). It was also carried out the socioeconomic characteristics of students through IFRN own data. Concerning the analysis of data was performed a descriptive analysis of the variables by their absolute and relative frequencies and measures of central tendency. The chi-square test was used to assess the association between the dependent variable and the independent categorical variables and the Student t test for quantitative. It was also conducted a further multiple analysis out using Poisson regression with robust variance between the outcome "presence of impact" and the independent variables that showed p <0.20. It was used for all the statistical tests a significance level of 5%. Among the adolescents surveyed, 51.16% reported that at least one activity assessed by OIDP had hampered its implementation due to some dental problem. The difficulties were more pronounced in the activities of eating (31.6%), oral hygiene (25.6%) and smile (25.1%).The tooth position, followed by toothache, were the causes of the impacts reported by most teenagers. There was a significant association between the presence and impact of the presence of one or more decayed teeth (p = 0.012), the presence of gum bleeding (p = 0.012) and for orthodontic treatment (p = 0.003), independently of other variables. There was no significant association between oral health status and socioeconomic and demographic characteristics of the adolescents. The survey results showed that there is an association between oral health status of the population studied and reports of difficulties in carrying out daily activities evaluated. The worse the oral health status, the greater the impact of this condition on the adolescents quality of life

Prevalência de incontinência urinária e fatores associados em idosos institucionalizados

Urinary incontinence (UI) is a geriatric syndrome that is especially prevalent in institutionalized individuals, and that causes economic and social impacts derived from treatment costs and overload of caregiver. UI also entails physical consequences to the health of the elderly, such as urinary tract infections or pressure ulcers, among other health problems. However, the existing national research on this condition is still scarce and comprises serious methodological biases. Therefore, the objective of this study is to determine the prevalence of urinary incontinence and associated factors in institutionalized elderly. A cross-sectional study is presented herein, conducted between October and December, 2013 and carried out in 10 nursing homes in the city of Natal (Northeast Brazil). UI was verified through the program Minimum Data Set version 3.0, which was also used to assess fecal incontinence, urinary devices and UI control programs. Data collection included sociodemographic information, UI characterization, as well as variables related to the institution itself and to health conditions (comorbidities, medication, pelvic floor surgery, Barthel Index for functional capacity and Pfeiffer test for cognitive status). Bivariate analysis was performed using the Chi-Square Test (or Fisher‟s Exact Test) and the Linear Chi-Square Test, calculating the prevalence ratio with 95% confidence interval. Variables with p value under 0.20 were included in the multivariate analysis, which was performed using the Stepwise Forward logistic regression. The inclusion of variables in the final model depended on the likelihood ratio test, absence of multicollinearity and on the Hosmer-Lemeshow test. A statistical significance level of 0.05 was considered. Six (1.8%) hospitalized elderly, one individual in palliative care (0.3%) and one (0.3%) individual under the age of 60 were excluded from the study. The final sample consisted of 321 elderly, mostly females, with a mean age of 81.5 years. The prevalence of UI was 59.43% and the final model revealed statistically a significant association between UI and white race, physical inactivity, stroke, mobility constraints and cognitive decline. The most frequent UI type was functional UI due to physical or cognitive disability, and incontinence control measures were applied only to a minority of residents (approximately 8%). It is concluded that UI is a health issue that affects more than half of the institutionalized elderly, and is associated with white race, physical inactivity, stroke and other geriatric syndromes such as immobility and cognitive disability. Most of these associated factors are modifiable and therefore the findings of this study highlight the importance of UI prevention and treatment in nursing homes, which include general measures, such as physical and psychosocial activities, and specific measures, such as prompted voiding

Prevalência e fatores associados ao risco e a desnutrição em idosos institucionalizados

One of the most important problems in the elderly is a nutritional deficiency. Several physiological changes and the use of multiple drugs interfere with appetite, food intake and absorption of nutrients, which can lead to the risk and malnutrition in the elderly, especially among institutionalized. The present study aimed to evaluate the prevalence of malnutrition and risk for malnutrition and its associated factors in institutionalized elderly. The same can be characterized by the type individual, observational and cross-sectional. Obtaining the sample was through the records of individuals of long-stay institutions for the elderly in the city of Natal, RN. The elderly were evaluated through the Mini Nutritional Assessment (MNA) and triceps skinfold (TSF) and each senior or caregiver answered a questionnaire about information like type and dietary restrictions, accessibility to food, use of alcohol and tobacco, practice physical activity and appetite. Variables such as age, gender, education, marital status, time that the elderly living in the institution, the reason for the institutionalization and comorbidities were taken from the records of each senior. The frequency of food consumption of various food groups was assessed from the questionnaire frequency of feeding study Health, Wellbeing and Aging (HWA). Data were presented as means and standard deviations, absolute and relative frequencies. To analyze the frequency of consumption, there was a factor analysis with extraction of factors from the principal components analysis with varimax rotation. A bivariate analysis was performed using the chi-square and the magnitude of the effect observed by prevalence ratio (95% CI). The Poisson regression assessed the net effect of independent variables on the two outcomes, considering a significance level of 5%. We studied twelve Homes for the Aged totaling 381 seniors eligible for the study. The prevalence of risk of malnutrition was 46.1% (45.9 to 46.2) and malnutrition was 31.4% (31.2 to 31.5). The risk of malnutrition was significantly associated with the presence of urinary incontinence (RP = 1.444, 1.113 to 1.874) was associated with malnutrition and lack of appetite (RP = 1.757, 1.246 to 2.476), the fact that the individuals do not have access to food outside the institution (RP = 0.565, 0.337 to 0.946), low water consumption (RP = 1.646, 1.101 to 2.459) and dementia (PR = 1.537, 1.072 to 2.204). The high prevalence of malnutrition and risk of malnutrition in the study suggests that we should pay attention to information related to eating habits and the presence of comorbidities, as these can influence the nutritional status of this population

Redução da mortalidade após implementação de condutas consensuais em pacientes com infarto agudo do miocárdio

OBJETIVO: Comparar a mortalidade em 30 dias com a utilização de determinados grupos de medicamentos por pacientes, entre 1992-1997, quando não se dispunham de condutas consensuais para tratamento do infarto agudo do miocárdio, e de 2000-2002, após a padronização dessas condutas em nosso serviço. MÉTODOS: Avaliados, retrospectivamente, no 1º e 2º períodos, 172 e 143 pacientes respectivamente, admitidos com diagnóstico de infarto agudo do miocárdio: foram realizados os testes estatísticos: c² para comparar proporções, teste t de Student e o de Mann-Whitney para comparação de médias ou medianas. RESULTADOS: A análise não mostrou diferença em relação aos homens, brancos e a idade média de 61 anos, nos dois períodos. Com relação aos fatores de risco clássicos, foi observada diferença apenas na incidência de dislipidemia (17 e 29%) e, quanto à estratégia terapêutica, aumento significativo do uso de: trombolíticos (39 e 61,5%), ácido acetilsalicílico (70,9 e 96,5%), betabloqueadores (34,8 e 67,8%), inibidor da enzima conversora da angiotensina (45,9 e 74,8%), nitratos (61 e 85,3%) e a redução significativa de bloqueadores de cálcio (16,8 e 5,3%), antiarrítmicos (29,1 e 9,7%) e diuréticos (50,6 e 26,6%). O uso de inotrópicos não diferiu entre os períodos (29,6 e 32,1%). A mortalidade em 30 dias apresentou redução estatisticamente significante de 22,7 para 10,5%. CONCLUSÃO: A implementação das condutas consensuais para o tratamento do infarto agudo do miocárdio foi acompanhada por significante redução da taxa de mortalidade em 30 dias.

Morphometric study of placental villi and vessels in women with mild hyperglycemia or gestational or overt diabetes

In this study, morphometric measures of placental terminal villi and villous vessels were compared in overt, as well as gestational diabetes mellitus, and mild hyperglycemia diagnosed by oral 100 g glucose tolerance test (100 g-OGTT) and glucose profile (GP). At delivery (gestational age >= 34 weeks) a total of 207 placentas were assigned to a control group (n = 56) or to one of three groups complicated by mild hyperglycemia (n = 5 1), gestational diabetes (n = 59) and overt diabetes (n = 4 1). Placenta samples were randomly selected for blind morphometric assessment with an image analyser. Morphometric measures obtained included area and number of terminal villi and their respective villous vessels. Statistical analyses were performed using the chi-square test, ANOVA and stepwise regression (p <= 0.05). Glycemic means were 86.2 mg/dL in controls, 98.9 mg/dL in mild hyperglycemia, 114.1 mg/dL in gestational diabetes and 122.1 mg/dL in overt diabetes. Our results show that abnormal maternal glycemic levels may change the placental morphometric characteristics related to materno-fetal exchanges. (C) 2007 Elsevier B.V.. All rights reserved.

TRAIL-R3-related apoptosis: Epigenetic and expression analyses in women with ovarian neoplasia

Objective. To assess the expression of TRAIL-R3 and the methylation of a CpG island within the TRAIL-R3 promoter both in cystadenoma tumors and primary and metastatic epithelial ovarian carcinoma (EOC).Methods. RNA was obtained from women with normal ovarian (NO) tissues (n = 18), ovarian serous cystadenoma tumors (n = 11) and EOC (n = 16) using Trizol (R). Quantitative PCR (gRT-PCR) was performed to quantify the relative levels of TRAIL-R3. The methylation frequency of the CpG island in the TRAIL-R3 promoter was assessed using the methylation-specific PCR (MSP) assay after DNA bisulfite conversion. The differences between the groups were evaluated using the chi-square, Student's t, ANOVA, Mann-Whitney U, Wilcoxon or Kruskal-Wallis tests as indicated. The survival rates were calculated using the Kaplan-Meier method.Results. Cystadenoma and metastatic EOC tumors expressed significantly more TRAIL-R3 mRNA than primary EOC tumors. Methylation of the TRAIL-R3 promoter was absent in NO tissues, while hemimethylation of the TRAIL-R3 promoter was frequently found in the neoplasia samples with 45.4% of the cystadenoma tumors, 8.3% of the primary EOC samples and 11.1% of the metastatic EOC samples showing at least partial methylation (p = 0.018). Neither the expression of TRAIL-R3 nor alterations in the methylation profile were associated to cumulative progression-free survival or the overall survival in EOC patients.Conclusions. Primary EOC is associated to a lower TRAIL-R3 expression, which leads to a better understanding of the complex disease and highlighting potential therapeutic targets. Promoter DNA methylation was not related to this finding, suggesting the presence of other mechanisms to transcriptional control. (C) 2012 Elsevier B.V. All rights reserved.

Associação glicemia de jejum e fatores de risco como teste para rastreamento do diabete gestacional

OBJETIVOS: comparar dois testes de rastreamento do diabete gestacional. MÉTODOS: estudo prospectivo no qual foram avaliadas 356 gestantes, sem diagnóstico prévio do diabete melito, submetidas, de modo independente, a dois testes de rastreamento: associação glicemia de jejum e fator de risco (GJ+FR) e teste oral simplificado de tolerância à glicose (TTG50g). A comparação entre os métodos foi realizada pelos índices de sensibilidade (S), especificidade (E) e valores preditivos positivo (VPP) e negativo (VPN), resultados falsos, positivos (FP) e negativos (FN) e pela diferença dos resultados observados e esperados, avaliada pelo teste do Qui-quadrado (p<0,05). RESULTADOS: a associação GJ+FR determinou a confirmação diagnóstica em maior número de gestantes (187; 52,5%) que o TTG50g (49; 13,8%). Esta diferença foi significativa (p<0,05). A associação GJ+FR apresentou sensibilidade de 83,7% e valor preditivo negativo (VPN) de 95,3% em relação ao TTG50g. CONCLUSÕES: os índices elevados de sensibilidade e VPN da associação GJ+FR em relação ao TTG50g, sua simplicidade, praticidade, baixo custo e fácil replicação permitem sua indicação no rastreamento do diabete gestacional.

Cirurgia não ginecológica em pacientes com câncer de ovário

OBJETIVO: avaliar a freqüência da utilização de procedimentos cirúrgicos não ginecológicos no tratamento do câncer de ovário, assim como descrever as suas complicações. MÉTODOS: foram incluídas retrospectivamente 82 pacientes, atendidas no período de fevereiro de 1999 a outubro de 2003, e que haviam sido submetidas a laparotomia para tratamento cirúrgico do câncer de ovário. Foram incluídas no estudo apenas pacientes com adenocarcinoma epitelial de ovário. A média de idade foi de 54,1±15,1 anos, variando de 22 a 89 anos. O estadiamento (FIGO) mostrou 5 pacientes no estádio I (6,1%), 18 pacientes no II (21,9%), 40 pacientes no III (48,8%) e 19 pacientes no IV (23,2%). As pacientes foram divididas em 2 grupos: aquelas em que foram realizados exclusivamente procedimentos ginecológicos e aquelas com realização de procedimentos não ginecológicos. As diferenças entre as médias foram analisadas pelo teste t de Student. As comparações entre grupos independentes foram feitas pelo teste do chi2. RESULTADOS: em 35 pacientes (42,7%) foram realizados procedimentos cirúrgicos não ginecológicos, incluindo: 17 colostomias, 16 enterectomias, oito peritonectomias pélvicas, sete colectomias, cinco ressecções parciais de cúpula frênica, quatro cistectomias parciais, quatro esplenectomias, duas ileostomias e uma hepatectomia parcial. Todas as pacientes submetidas a procedimentos não ginecológicos apresentavam-se nos estádios III e IV. Esse grupo apresentou maior tempo cirúrgico (5,3±1,4 versus 3,1±0,9 horas); p<0,001). Os grupos não mostraram diferenças significativas em relação à necessidade de hemotransfusão (42,2 versus 40%; p=0,512) e tempo de internação (11,5±7,2 versus 10±9,9 dias; p=0,454). A realização de procedimentos cirúrgicos não ginecológicos associou-se a maior taxa de complicações pós-operatórias 37% versus (17,1%; p=0,042), sendo que duas pacientes desse grupo (2,4%) evoluíram para o óbito. CONCLUSÕES: os procedimentos cirúrgicos não ginecológicos são freqüentemente empregados no tratamento de pacientes com câncer de ovário. A realização dessas cirurgias está associada a maior tempo cirúrgico e maior taxa de complicações pós-operatórias.

Environmental risk factors for canine toxoplasmosis in a deprived district of Botucatu, SP, Brazil

Toxoplasmosis is a worldwide zoonosis caused by Toxoplasma gondii that can infect a large variety of animals, including humans. The present study aimed to evaluate the frequency of anti-T. gondii antibodies in dogs from a peripheral district of Botucatu and to establish the association among some epidemiological variables in order to evaluate risk factors for toxoplasmosis infection. Serum samples from dogs were screened using an indirect fluorescent antibody (IFA) test. Anti-T. gondii antibody prevalence was 56%. The highest titer was 1024 (1.79%) and the most frequent titers were 16 (57.14%) and 64 (33.93%). The chi-square (X-2) test revealed significant association among variables such as dog access to street, ingestion of raw meat and presence of synantropic animals in the domestic environment. These results demonstrate that toxoplasmosis is present in dogs from Jardim Santa Elisa district.
