Abstract: due to the high prevalence and morbidity sexually transmitted diseases are highly relevant to public health, especially for women. objectives: to determine and compare the behavioral and biological risks associated with human immunodeficiency virus acquisition. methods: a group of 253 women who voluntarily sought anonymous testing were interviewed to find out their behavioral risk. biological risk was identified by means of gynecological exam, colposcopy as well as blood and cervicovaginal sampling for serological and microbiological exams. using known traditional risk factors, a table of scores classified the subjects into high, low and absent for behavioral and biological risks. frequency and percentage of each risk was tabulated and the correlation between risks was obtained by calculating the kappa statistic. results: 79.8% of subjects were found to have behavioral risks, and 79.1% biological risks. it was also found that 66.7% of the women (169) with high behavioral risk also had high biological vulnerability. however, 31 out of 51 women without any behavioral risk had biological vulnerability 12.2 %. the kappa statistic demonstrated low agreement between the latter risks [k = 0.05 95% ci (-0.06 to 0.17)]. conclusion: women who seek care in centers for anonymous testing have high biological risk, which is neither proportional nor concurrent to behavioral risk. the low concordance found between these risks suggests the need for routine gynecological investigation (clinical and microbiological) for all women.

Abstract: this study evaluated the effectiveness of papanicolaou staining for the initial diagnosis of chlamydial infection in pregnant women. a hundred thirteen patients were examined with a papanicolaou test, independent of gestational age, parity or maternal age. three endocervical samples were collected; the first two were collected with a brush (cytobrush plus, mediscand, sweden) and the third with ayre's spatula. the first specimen was used for mccoy cell culture and the other two were examined cytologically. chlamydial infection was detected in 9 (7.9%) patients. only one (0.8%) was diagnosed by cytological exam. the sensitivity and specificity of the cytological examination were 10 and 98%, respectively. the estimated positive predictive value was 33.3% and the negative predictive value was 92.7%. when papanicolaou stain diagnosis suggests chlamydia, a more specific complementary exam should be added to confirm infection; subsequently adequate treatment can be implemented, thereby preventing the frequent complications of untreated subclinical infections.

Abstract: Several methodologies in molecular biology have been used in theinvestigation of Malassezia pachydermatis and its differentiation into subtypes. Recent molecular research of this species includes the use of samples isolated from canine otitis externa and dermatitis, as well as from healthy animals, having in view an epidemiologicalstudy of the yeast. The aim of this study was to identify molecular differences in M. pachydermatis samples isolated from dogs with otitis externa. The M. pachydermatis strains were analyzed by means of the Random Amplification Primer DNA - Polimerase Chain Reaction (RAPD–PCR) for molecular heterogeneity research. DNA extraction was carried out with phenol-chloroform and the RAPD technique using the AGAATCCGCC primer. A variation was observed in the number and arrangement of the bands among the 49 studied isolates, grouped into nine patterns. Isolate groupings were not found to be related to animal breed, age or sex. It was concluded that M. pachydermatis has differences in its molecular profile, as shown by the molecular technique (RAPD – PCR), which allows isolates to be classified into nine subtypes. Várias metodologias em biologia molecular têm sido aplicadas para estudar a M. pachydermatis diferenciando-a em subgrupos. Recentemente utiliza-se a investiga o molecular desta espécie isolada de otite externa e dermatite, e também de isolados da mesma de animais hígidos, para um estudo epidemiológico da levedura. O objetivo deste trabalho foi identificar diferen as moleculares entre isolados de M. pachydermatis obtidos de casos de otite externa canina. Para isto, amostras da levedura provenientes de c es com esta enfermidade foram estudadas através da técnica de Polimorfismo de DNA Amplificado aoAcaso - Rea o da Polimerase em Cadeia (RAPD–PCR) para pesquisa de heterogeneidade molecular. A extra o de DNA foi realizada no processo fenol-cloroformio e a técnica de RAPD foi estudada com o primer AGAATCCGCC. Pode-se observar com esta metodologia, varia o no número e posi o das bandas entre os 49 isolados estudados, podendo-se agrupá-los em nove padr es. Os agrupamentos formados pelos isolados n o apresentaram rela o com ra a, idade ou sexo do animal. Concluindo-se que a M. pachydermatis apresenta diferen as em seu perfil molecular, observado pela técnica molecular (RAPD-PCR) que permite classificar os isolados desta espécie em até nove subtipos.

Abstract: female genital ulcer is a disease that affects a large number of women, and its etiologic diagnosis can be difficult. the disease may increase the risk of acquiring hiv. genital ulcer may be present in sexually transmitted diseases (std) - syphilis, chancroid, genital herpes, donovanosis, lymphogranuloma venereum and other non-std disorders (nstd) - beh?et's syndrome, pemphigus, crohn's disease, erosive lichen planus and others. this study evaluated the clinical-histopathologic-microbiologic characteristics of female genital ulcers. a cross-sectional descriptive prospective study was conducted during a six-month period to investigate the first 53 women without a definitive diagnosis, seeking medical care for genital ulcers at a genital infections outpatient facility in a university hospital. a detailed and specific history was taken, followed by a dermatologic and gynecologic examination. in addition to collecting material from the lesions for microbiologic study, a biopsy of the ulcer was performed for histopathologic investigation. the average age of the patients was 32.7 years, 56.6% had junior high school education and higher education. the most frequent etiology was herpetic lesion, followed by auto-immune ulcers. at the time of their first consultation, around 60% of the women were using inadequate medication that was inconsistent with the final diagnosis. histologic diagnosis was conclusive in only 26.4% of the patients (14/53). cure was obtained in 99% of the cases after proper therapy. the female genital ulcers studied were equally distributed between sexually transmitted and non-sexually transmitted causes. herpes was the most frequent type of genital ulcer, affecting women indiscriminately, mostly between the ages of 20 and 40 years. the etiologic diagnosis of herpetic ulcers is difficult to make even when various diagnostic methods are applied. it is imperative that nstd should be included in the differential diagnoses of female genital ulcers. the histo

Abstract: background: malnutrition is frequent in cirrhotic patients, and its assessment is difficult. functional assessment through a dynamometer is a simple method and could minimize these drawbacks. harris-benedict prediction formulae estimates the resting energy expenditure but has not been validated for this population. one alternative is the use of indirect calorimetry. aim: to assess nutritional status in cirrhotic patients and estimates the resting energy expenditure through indirect calorimetry and compares it to harris-benedict. patients and methods: thirty four adult hepatitis c cirrhotic outpatients were studied, classified by child-pugh and model of end-stage liver disease score. the resting energy expenditure was predicted through harris-benedict and measured by indirect calorimetry. nutritional assessment was done through anthropometry, subjective global assessment, hand-grip strength and a 3-day recall. results: fifteen (44.2%) were child-pug a, 12 (35.3%) b and 7 (20.6%) c, and 33 (97.1%) had model of end-stage liver disease scores less than 20. the resting energy expenditure predicted was higher than the measured (harris-benedict 1404.5 ± 150.3 kcal; indirect calorimetry 1059.9 ± 309.6 kcal). the prevalence of malnutrition varied between methods (body mass index, muscle arm circumference, subjective global assessment, triceps skinfold thickness and hand-grip strength: 0; 5.9; 17.6; 35.3 and 79.4%, accordingly). calories and proteins intake were 80% and 85% of recommended amounts and there was inadequate intake of calcium, magnesium, iron and zinc. conclusion: malnutrition was frequent and hand-grip strength seemed to be the most sensitive method for its diagnosis. calories and protein intakes were inadequate. considering that the predicted resting energy expenditure was higher than the measured one and the need to offer higher caloric intake, the use of the predicting equation may replace indirect calorimetry.

Abstract: Este trabalho teve como objetivo contemplar a quest o do deslocamento do acento na aquisi o de segunda língua (L2). Para tanto, partiu-se da análise de um corpus constituído pelas produ es que os indivíduos pesquisados (dez alunos do ensino médio e cinco professores) realizaram para oito palavras da língua inglesa assinaladas pela quest o da modifica o do padr o acentual por falantes que têm como primeira língua (L1) o português brasileiro. Percebeu-se que o deslocamento parece ser motivado por processos de transferência da estrutura silábica em L1 para comunicar-se em L2, o que pode ser representado por um modelo autosegmental. Os dados parecem apontar na dire o de que a ausência ou ineficácia de insumo fornecido ao aluno, parece responder pelas dificuldades na aquisi o e produ o de L2 em sua modalidade oral. This work aimed at addressing the issue of displacement of accent in second language (L2) acquisition. To do so, we performed an analysis of a corpus constituted by the productions that the surveyed individuals (ten high school students and five teachers) performed for eight English words which are likely to be object of change of the stress pattern when produced by speakers who have, as first language (L1), Brazilian Portuguese. It was noticed that the shift seems to be driven by processes of transference of the syllabic structure in L1 to communicate in L2, which can be represented through an autosegmental model. The research data seems to point towards the fact that the lack or ineffectiveness of input provided to the student, accounts for the difficulties in the acquisition and oral production of L2.

Abstract: dry matter intake (dmi) of coastcross bermudagrass grazing by crossbred holstein-zebu and zebu lactating cows was calculated using in vitro dry matter digestibility from extrusa (four esophageal fistulated cows) and fecal output estimate with mordent chromium by the non linear model. pasture was managed in a rotational system with three days of occupation and 27 days of resting period, adopting a stocking rate of 1.6 and 3.2 cows/ha respectively during the dry and rainy season. four different equations based on ruminal degradation were used to predict dry matter intake: dmi = -1.19 + 0.035 (a+ b) + 28.5c (1), dmi = -0.822 + 0.0748 (a+ b) + 40.7c (2), dmi = -8.286 + 0.266a + 0.102b +17.696c (3) and dmi = [%fdn na ms]* [fdn intake] / [(1-a-b)/kp +b/(c+ kp)]/24] (4). the coast-cross dmi predicted by the equations were different from results obtained with the model (6.3 kg of dry matter/cow/day). the data achieved using the equations 1 and 2 (12.2 and 12.7 kg/cow/day respectively) were similar and superior from results obtained by equation 4 (7.8 kg/cow/day). those values overestimated the results obtained using mordent chromium. the data obtained by equation 3 (5.5 kg/cow/day) was lower than those determined by equations and underestimated the dmi calculated with external marker. the prediction of dry matter intake from cows grazing tropical forages using equations based in ruminal degradation parameters constitutes an important potential for those evaluations, but it should be still studied before being employed in practice.
