Abstract
Background: Tobacco use accelerates atherosclerosis and is one of the predictors of death from ischemic heart disease, arrhythmias, heart failure, and sudden death. A new non-invasive parameter, the Index of Cardiac Electrophysiological Balance (iCEB) between depolarization and repolarization of the action potential, was considered a new biomarker for the identification of patients at increased arrhythmic risk. Objectives: We aimed to evaluate the iCEB in apparently healthy Angolans with habitual cigarette smoking compared to non-smokers. Subjects and methods: Data were obtained from the CardioBengo study, a cross-sectional community-based study in which a random sample of individuals aged between 15 and 84 years was selected. In total, 214 apparently healthy subjects, 102 smokers, and 112 non-smokers in the same age group were included in the final analysis. Results: The average age of the participants was 42.17 ± 13.04 years old and 26.6% of the sample was female. Smoking subjects had higher iCEB and corrected Index of Cardiac Electrophysiological Balance (iCEBc) values compared with non-smoking controls (4.39 vs. 4.25; p = 0.024, respectively), and (4.74 vs. 4.57; p = 0.030, respectively). Conclusions: In summary, iCEB and iCEBc were significantly higher in habitual smokers than in nonsmokers, which represents an increased risk of ventricular arrhythmogenesis in healthy habitual smokers. To the best of our knowledge, this is the first study performed in Africa to evaluate iCEB in smokers, making this type of study very important in low- and middle-income countries in the context of epidemiological transition.

Abstract
Prosthetic valve thrombosis is a serious complication of valve replacement associated with a high mortality rate. Stroke may be the first symptom of prosthetic valve thrombosis. We present the case of a patient who visited the emergency department with symptoms of dysarthria and left hemiparesis. An examination revealed an ischemic stroke with hemorrhagic transformation, stemming from a thrombosis of their mitral valve prosthesis, which progressed to the patient's death. We emphasize the difficulty in the therapeutic and diagnostic management of these patients.

Abstract
Aims To identify the prevalence of major and minor electrocardiographic abnormalities and their association with the main risk factors for cardiovascular disease in a population in the province of Bengo, northern Angola. Methods A cross-sectional community-based study was conducted and a representative random sample stratified by sex and age was selected. In total, 2379 black individuals were included in the final analysis. A standard 12-lead ECG were recorded from all participants, analyzed and processed by the University of Glasgow software and coding by the Minnesota code. Results 22.3% of participants had minor electrocardiographic abnormalities and 4.58% major ECG abnormalities. The most common minor ECG abnormalities were abnormal T wave inversion, minor isolated ST abnormalities and premature beats. The most common major ECG abnormalities were Left ventricular hypertrophy with major ST-T abnormalities, Ventricular conduction defects and major Q-wave abnormalities. Hypertension, diabetes mellitus, hypercholesterolemia, alcohol consumption and smoking, were significantly associated with major and minor electrocardiographic abnormalities. Conclusions In this study several participants had minor and major electrocardiographic abnormalities. Minor electrocardiographic abnormalities were more prevalent in men and major abnormalities in women. The electrocardiographic abnormalities had significant associations with the main cardiovascular risk factors.

Abstract
Leprosy epidemiological studies have been restricted to Mycobacterium leprae DNA detection in nasal and oral mucosa samples with scarce literature on peripheral blood. We present the largest study applying quantitative real-time PCR (qPCR) for the detection of M. leprae DNA in peripheral blood samples of 200 untreated leprosy patients and 826 household contacts, with results associated with clinical and laboratory parameters. To detect M. leprae DNA a TaqMan qPCR assay targeting the M. leprae ML0024 genomic region was performed. The ML0024 qPCR in blood samples detected the presence of bacillus DNA in 22.0% (44/200) of the leprosy patients: 23.2% (16/69) in paucibacillary (PB), and 21.4% (28/131) in multibacillary (MB) patients. Overall positivity among contacts was 1.2% (10/826), with similar percentages regardless of whether the index case was PB or MB. After a follow-up period of 7 years, 26 contacts have developed leprosy. Comparing the results of healthy contacts with those that become ill, ML0024 qPCR positivity at the time of diagnosis of their index case represented an impressive 14.78-fold greater risk for leprosy onset (95% CI 3.6-60.8; p <0.0001). In brief, contacts with positive PCR in blood at diagnosis of index cases are at higher risk of later leprosy onset and this marker might be combined with other prognostic markers for management of contacts, which requires further studies.

Abstract
BACKGROUND A high carotid-femoral pulse wave velocity (PWV) has been related to increased cardiovascular morbidity and mortality, but has not been previously evaluated in amputees. The aim of this study was to compare PWV between amputees and nonamputees. METHODS In this cross-sectional study, data were collected from 60 male lower limb amputees and 86 male age-matched nonamputees. PWV was measured noninvasively using a Complior(®) device. All participants underwent laboratory investigations and anthropometry. The difference in PWV between amputee and nonamputees was estimated. Multivariate regression was used to adjust for differences between the groups as a result of potential confounders. RESULTS PWV was higher in amputees than in nonamputees (10.8 ± 1.9 m/sec versus 9.9 ± 1.8 m/sec, P = 0.008, respectively). This difference remained even after adjusting for confounding factors. CONCLUSION A higher PWV was demonstrated in lower limb amputees. Routine assessment of PWV may contribute to cardiovascular risk stratification in amputees.

Abstract
BACKGROUND AND PURPOSE To evaluate the effect of one month of continuous positive airway pressure (CPAP) in a subgroup of obstructive sleep apnea (OSA) patients with erectile dysfunction (ED) and compare this subgroup with age- and body mass index (BMI)-matched OSA patients without ED. PATIENTS AND METHODS Prospective general, sleep, psychiatric and sexologic evaluations were conducted. Epworth Sleepiness Scale (ESS), Beck Depression Inventory (BDI), Sleep Disorders Questionnaire (SDQ), Quality of Life SF-36, and polysomnography were used. Seventeen OSA patients with ED were compared prior to CPAP treatment and during CPAP treatment with age- and BMI-matched OSA patients without ED. Parametric and non-parametric statistics, chi-square, Fisher exact test and multiple regression analyses were performed. RESULTS Ninety-eight men (BMI=28.8 kg/m2, apnea-hypopnea index (AHI)=49.6 events/h, ESS=14.8, BDI=8.4, and lowest SaO2=75.3%) were divided into subgroups of lowest SaO2>80% (A) and lowest SaO2< or =80% (B). (A) Forty-six men had a mean lowest SaO2 of 85.7%+/-2.9, AHI=29.5+/-17.6, age=46.3+/-9.3 years, ESS=13.6+/-4.2, BMI=25.8+/-4.8. Seven of the patients had ED. (B) Fifty-two men had a mean lowest SaO2=60.10+/-10.0%, AHI=67.4+/-24.5, BDI=9.0+/-6.9, age=47.4+/-9.4 years, ESS=16.2+/-4.4, BMI=31.4+/-5.1. Twenty-one of the patients had ED (chi2: P=0.006). Significant variables for ED were lowest SaO2 and age (r=0.17). CPAP-treated subgroup: ED subjects had significantly lower SaO2, ESS, BDI and SF-36 subscale scores than OSA controls. Nasal CPAP eliminated the differences between groups, and ED was resolved in 13 out of 17 cases. CONCLUSIONS ED in OSAS is related to nocturnal hypoxemia, and about 75% of OSAS patients with ED treated with nasal CPAP showed remission at one-month follow-up, resulting in significant improvement in quality of life.

Abstract
OBJECTIVE To prospectively evaluate the relationship between obstructive sleep apnea syndrome (OSAS), nocturia and quality of life in elderly patients free of the urologic and medical conditions that lead to increased nocturia. METHODS Prospective study of nocturia in men 65 years and older with isolated OSAS or sleep onset insomnia. After a 7-day nocturia evaluation and nocturnal polysomnography, Epworth Sleepiness Scale (ESS), Beck Depression Inventory (BDI), Quality of Life (SF-36) were administered. RESULTS OSAS patients with frequent nocturia had significantly greater body mass index (BMI), greater apnea-hypopnea index (AHI), lower lowest oxygen saturation and lower SF-36 subscale scores. Treatment with nasal continuous positive airway pressure (CPAP) for OSAS and behavioral techniques for insomnia improved ESS and BDI scores for all three groups. SF-36 subscale scores improved more in subjects with multiple nocturia. AHI and BMI explain 38% of the variance for nocturia. CONCLUSION Nasal CPAP reduces OSA and nocturia and improves quality of life of elderly patients.

Abstract
INTRODUÇÃO: A oxibutinina atua como agente anticolinérgico que tem ação anti-muscarínica e, principalmente, ação antiespasmódica na musculatura lisa vesical. Assim, ela causa aumento da capacidade vesical e diminui a frequência miccional e bloqueia o estímulo inicial da micção. OBJETIVO: Verificar se a oxibutinina atua sobre a hiperatividade vesical causada pela cistite hemorrágica, dependente do óxido nítrico. MÉTODOS: Foram estudados dois grupos de animais. O controle com 5 ratas e o experimental com 10 ratas, cujos pesos variaram entre 200g a 250g. A cistite hemorrágica foi provocada pela injeção intraperitoneal de ciclofosfamida 200mg/kg, na véspera do experimento. Após 24 horas, as ratas foram anestesiadas com uretana 1,25mg/kg. A seguir, foi feita cistostomia com cateter P-50. Esse cateter foi conectado em Y a uma bomba de infusão contínua com fluxo de água de 0,3ml/min e a um polígrafo para o registro da cistometria. O registro cistométrico foi feito com a velocidade do papel de 0,05cm/seg, com sensibilidade de 20 e calibração para um curso de 60mm para uma pressão de 100mmHg. Os parâmetros estudados foram: freqüência de contração (Fc), intensidade das contrações (Ic), tempo de enchimento vesical (Te), tempo de contração vesical (Tc) e capacidade vesical (Cv), que foi determinado pelo Te x Fluxo. Esses parâmetros foram determinados por suas médias durante o período de observação de 10 min. Após o registro, foi infundido por gavagem 71 mg/kg de cloridato de oxibutinina. Uma hora depois foi feita nova cistometria. A análise estatística foi feita pelo método de Kruskal-Wallis que comparou os valores do grupo controle com o experimental. O p foi considerado significante quando menor que 0,05. RESULTADOS: A comparação entre os dois grupos dos parâmetros estudados antes da infusão do cloridrato de oxibutinina mostrou: Fc - p=0,007; Ic - p=0,0002; Te - p=0,768; Tc - p=0,492; Cv - p=0,056 A comparação dos parâmetros estudados depois da droga mostrou: Fc - p= 0,055; Ic - p=0,0002; Te - p=0,957; Tc - p=0,181; Cv - p=0,206. CONCLUSÕES: O cloridrato de oxibutinina nesse modelo experimental atuou de forma a alterar somente a freqüência das miccções, controlando a hiperatividade e não promovendo alterações nos demais parâmetros estudados.

Abstract
Gene therapy aims to complement or, ideally, correct defective genes. The broad clinical application of this emerging technology requires the development of safe high-capacity gene delivery vehicles that combine efficient transduction of dividing as well as quiescent cells with sustained transgene expression. Here we present a new hybrid vector system that unites favorable attributes of adenoassociated virus (AAV) and adenovirus (Ad) vectors in a single particle. This was achieved by inclusion of Ad packaging elements in different sized recombinant AAV genomes. In the presence of AAV replicative functions and a recombinant helper Ad, AAV/Ad hybrid particles were generated via encapsidation of AAV-dependent replicative intermediates into Ad capsids. In stringent in vitro models based on transduction of proliferating cells we show that AAV/Ad hybrid vectors are superior to Ad vectors in establishing prolonged transgene expression and can be used to deliver DNA fragments of at least 27 kb.

Abstract
Eight capuchin monkeys (Cebus apella) were vaccinated against rabies with an inactivated suckling mouse brain vaccine (SMBV). Three 1-ml doses of 2% brain tissue suspension were given by i.m. injection at 0, 30, and 60 days. Blood samples were collected at 0, 30, 60, 90, 150, 210, 240, 300, and 365 days and were tested by simplified fluorescence inhibition to titer-neutralizing antibodies. All of the animals developed neutralizing antibodies with titers >0.5 IU/ml after vaccination, but the immune response persisted for only 122.3 +/- 32.6 days. The SMBV was able to induce immune response in the capuchin monkeys, but protection was short-lived.

Abstract
Among HIV-positive women, infection with multiple human papillomavirus (HPV) types is known to be more frequent and persistent, as well as a greater prevalence of high-grade genital lesions. This study aims to characterize, for the first time in Brazil, HPV presence and types among HIV-positive women of a high-risk population for genital intraepithelial neoplasia (GIN) development. A non-anonymous, voluntary, cross-sectional epidemiological survey was conducted, from June 1996 to April 1997, among 141 HIV-positive women followed at the Center of Reference in AIDS (CRAIDS). They were submitted to gynaecological examination, cytological screening and biopsies whenever necessary, for GIN and HPV DNA detection through polymerase chain reaction (PCR) technique. Positive HPV DNA were found in 80.8% patients. Two or more HPV types were detected in 45% of the samples. The most frequent HPV types detected were 16, 18 (30.5%); 61, 53 (24.4%), and non-identified types (18.7%). According to the oncogenic potential, 34.8% were considered of high-risk types. Among these HIV-positive patients, a great variety of HPV types, including high-risk types, was found in anogenital environment, as well as among young women, a great prevalence of high-grade genital lesions. Thus, it should strengthen the need for a periodical careful gynaecological examination among those women.

Abstract
OBJECTIVE To evaluate by hysteroscopy and histopathology the influence of tamoxifen in the endometrium of post-menopausal women with previous breast cancer. METHOD Out of 46 patients studied, 20 of them had been using tamoxifen for an average length of 12 months, and are still being followed-up. Hysteroscopy with endometrial biopsy was performed before and after the use of the drug. RESULTS The prevalence of endometrial activity before and after this hormoniotherapy was the same, i.e. 10.0%, showing a non-significant variation. CONCLUSION The hormoniotherapy with tamoxifen has not increased the endometrial proliferactive activity of postmenopausal patients with breast cancer. The most common hysteroscopical finding was numerous vesicles disseminated throughout the uterine cavity probably due to atrophy of the endometrium.

Abstract
OBJECTIVE To study the uterine mucosa of women with breast cancer in order to evaluate the frequency of endometrial diseases. EXPERIMENTAL DESIGN Prospective, controlled study carried out from January to December 1996. SURROUNDINGS: Patients with breast cancer and normal controls from 4 out-patient university services in Porto Alegre, Brazil. PATIENTS Postmenopausal women without hormonal therapy were compared: 67 of them with breast cancer and 101 normal controls. METHODS Hysteroscopy followed by endometrial biopsy carried out in both groups as an out-patient procedure. RESULTS In patients with breast cancer, 29.85% abnormal biopsies were found as follows: 10 endometrial polyps (15.0%), 8 with proliferative changes (11.9%), 1 case of cancer (1.5%), and one case of hyperplasia (1.5%). In the control group 8% abnormal morphological findings were found, as follows: 4 (4%) with endometrial polyps and 4 (4%) with proliferative changes. The differences in abnormal biopsies were statistically significant, mainly in patients with corporal mass index above 27.3. The sensibility of hysteroscopy was 82.14%; its specificity 97.16%; its predictive positive value 85.18% and its predictive negative value 96.48% in detecting endometrial activity, for a prevalence of 16.7% of endometrial activity. CONCLUSIONS Endometrial evaluation must be included in the initial evaluation of patients with breast cancer, mainly if they were obese. Hysteroscopy, performed in out-patient basis, showed to be an adequate method to evaluate the uterine mucosa, helping to select the area of this cavity for biopsy.
