Clinical and quality-of-life outcomes after autologous fascial sling and tension-free vaginal tape: a prospective randomized trial

Purpose: Evaluate the impact autologous fascial sling (AFS) and tension-free vaginal tape (TVT) procedures on quality-of-life in incontinent women. Materials and Methods: Forty-one women were randomly distributed into two groups. Group G1 (n = 21), underwent AFS and group G2 (n = 20) TVT implant. The clinical follow up was performed at 1, 6, 12 and 36 months. Results: TVT operative time was significantly shorter than AFS. Cure rates were 71% at 1 month, 57% at 6 and 12 months in G1. In G2, cure rates were 75% at 1 month, 70% at 6 months and 65% at 12 months; there was no significant difference between groups. As regards the satisfaction rate, there was no statistical difference between groups. Analysis of quality of life at 36 months revealed that there was no significant difference between groups. Conclusion: Similar results between AFS and TVT, except for operative time were shorter in TVT.

A polymerase chain reaction for detection of Brucella canis in vaginal swabs of naturally infected bitches

A PCR assay for the detection of Brucella canis in canine vaginal swab samples was evaluated, comparing its performance with that of bacterial isolation, serological tests, and a blood PCR assay. One hundred and forty-four female dogs were clinically examined to detect reproductive problems and they were tested by the rapid slide agglutination test, with and without 2-mercaptoethanol (2ME-RSAT and RSAT, respectively). In addition, microbiological culture and PCR were performed on blood and vaginal swab samples. The results of the vaginal swab PCR were compared to those of the other tests using the Kappa coefficient and McNemar test. of the 144 females that were examined, 66 (45.8%) were RSAT positive, 23 (15.9%) were 2ME-RSAT positive, 49 (34.02%) were blood culture positive, 6 (4.1%) were vaginal swab culture positive, 54 (37.5%) were blood PCR positive, 52 (36.2%) were vaginal swab PCR positive, and 50.69% (73/144) were positive by the combined PCR. The PCR was able to detect as few as 3.8 fg of B. canis DNA experimentally diluted in 54 ng of canine DNA, extracted from vaginal swab samples of non-infected bitches. In addition, the PCR assay amplified B. canis genetic sequences from vaginal swab samples containing 1.0 x 10(0) cfu/mL. In conclusion, vaginal swab PCR was a good candidate as a confirmatory test for brucellosis diagnosis in bitches suspected to be infected, especially those negative on blood culture or blood PCR; these animals may be important reservoirs of infection and could complicate attempts to eradicate the disease in confined populations.

É descrito o carcinoma de células escamosas (CCE) no fundo vaginal de uma vaca. O diagnóstico de CCE moderadamente diferenciado foi confirmado através do exame histopatológico. Os testes imunoistoquímicos com os marcadores p53 e Ki67 realizados em amostras do tumor confirmaram a mutação na p53 e aumento da proliferação celular.

Presença de Candida nas mucosas vaginal e bucal e sua relação com IgA salivar

OBJETIVO: correlacionar a presença de leveduras do gênero Candida na cavidade bucal e vaginal de mulheres com e sem candidíase vulvovaginal (CVV) com os níveis de IgA secretora (IgAs) presentes na saliva. MÉTODOS: cinqüenta e uma mulheres foram incluídas; 13 apresentaram CVV e 38 formaram o Grupo Controle. de cada paciente, foram coletados 2,0 mL de saliva sem estimulação e secreção vaginal com o auxílio de swab, que foi imerso a seguir em 2,0 mL de solução fisiológica. As amostras foram semeadas em ágar Sabouraud dextrose com cloranfenicol para isolamento e contagem de colônias, e os isolados foram identificadas fenotipicamente. Na saliva de ambos os grupos foi quantificada IgA pela técnica ELISA. RESULTADOS: nas 13 pacientes com diagnóstico clínico e micológico de CVV, a média de unidades formadoras de colônias de Candida por mililitro de secreção vaginal (ufc/mL) foi de 52.723 e 23,8% dos pacientes apresentaram colonização na mucosa bucal com menor quantidade de ufc/mL (6.030). Os níveis de IgAs na saliva foram mais baixos no grupo com CVV (média de densidade: 0,3) quando comparados aos níveis de IgA do Grupo Controle (média de DO: 0,6). Onze pacientes (37%) do Grupo Controle apresentaram colonização por Candida na cavidade bucal, com média de ufc/mL mais baixa quando comparada ao grupo com CVV. O Grupo Controle também apresentou menor quantidade de ufc/mL (1.973) na cavidade vaginal quando comparado com o Grupo CVV (52.942). CONCLUSÕES: os resultados demonstraram que os pacientes com diagnóstico clínico de candidíase vulvovaginal apresentaram maior quantidade de Candida, tanto na cavidade vaginal quanto na bucal, e apresentaram menores níveis de IgA anti-Candida na saliva.

Caracterização fenotípica de leveduras isoladas da mucosa vaginal em mulheres adultas

OBJETIVO: caracterizar fenotipicamente leveduras isoladas do conteúdo vaginal de 223 mulheres adultas, sintomáticas (S) e assintomáticas (A) para vulvovaginite, e determinar os indicadores clínicos que possivelmente levam ao surgimento de sinais e sintomas relacionados ao acometimento da mucosa por essa patologia. MÉTODOS: inicialmente foi aplicado um questionário, com questões abertas e fechadas, sobre dados clínicos epidemiológicos. Logo, ocorreu o diagnóstico micológico com semeadura em meio Chrom Agar Candida, identificação micromorfológica e bioquímica. Métodos específicos para detecção de fatores de virulência, proteinase e fosfolipase foram empregados. A análise estatística das variáveis foi estabelecida utilizando os testes χ2 e χ2 de Pearson. RESULTADOS: Candida albicans foi a espécie mais prevalente (87%, S e 67%, A), seguida de Candida glabrata (4%, S e 17%, A). O número de mulheres que referiram adoção de anticoncepcionais foi mais alto entre as sintomáticas, 77%. Nos dois grupos estudados, em torno de 87% apresentaram ciclos menstruais regulares, 57% das mulheres eram casadas com idade entre 30 a 40 anos. em relação a práticas sexuais, houve para parte das pacientes, concomitância entre os hábitos, anal, oral e vaginal. em relação à fosfolipase, apenas Candida albicans produziu este fator de virulência em 37,5%. A proteinase foi detectada em Candida albicans, Candida glabrata e Candida parapsilosis. Esse último fator de virulência esteve associado, principalmente, a isolados de pacientes sintomáticas. CONCLUSÕES: a colonização e infecção da mucosa vaginal por levedura é real com diversas espécies de Candida presentes. No entanto, Candida albicans se destaca como espécie prevalente em mucosa vaginal de mulheres adultas. Fica evidente a emergência de espécies de Candida não albicans, algumas com resistência intrínseca aos azólicos, tais como Candida glabrata, Candida parapsilosis, Candida tropicalis, e Candida guillermondii, o que pode ser explicado pelo uso inadequado de medicamentos e tratamento empírico.

Quadro citológico vaginal, concentração plasmática de progesterona durante a gestação e medidas fetais em paca (Cuniculus paca Linnaeus, 1766)

Em 27 pacas (Cuniculus paca Linnaeus, 1766) objetivou-se descrever aos 30, 60 e 90 dias (D) de prenhez diagnosticada por ultrassonografia (US), os tipos celulares do epitélio vaginal em esfregaços vaginais, relatar as condições de abertura da vulva e as características do muco vaginal, determinar a concentração plasmática de progesterona (P4) por radioimunoensaio, e ainda, mensurar por ultrassonografia (US) o diâmetro biparietal (DBP) fetal aos 60 e 90 dias de prenhez. No D30, 40% das amostras exibiram células (com características estrogênicas) superficiais e presença de núcleos nus. Nos D60 e D90, células parabasais, intermediárias, superficiais e naviculares estavam presentes nas mesmas proporções, mas células endocervicais foram descritas em apenas 73,9% e 69% das amostras daqueles dias, respectivamente. No D30 a maior proporção de células naviculares e superficiais diferiu (p < 0,05) em relação aos outros tipos celulares presentes. O muco vaginal apresentou-se cristalino e fluido em 100% e em 70% das fêmeas nos D30 e D60, respectivamente. Observou-se o vestíbulo vaginal aberto em torno de 50% das fêmeas em todos os dias de exames. Valores mínimos detectáveis de P4 foram obtidos em 72% e em 83% das fêmeas, enquanto que as médias das medidas dos DBP foram 1,25 cm (± 0,16) e 2,34 cm (± 0,25) nos D60 e D90, respectivamente. O quadro citológico vaginal nos D30, D60 e D90 e o DBP fornecem elementos que contribuem para diagnóstico de gestação em pacas. A concentração de P4 demonstra a necessidade de maiores estudos da endocrinologia da gestação em pacas.

Clinicopathological features influencing pelvic lymph node metastasis and vaginal and parametrial involvement in patients with carcinoma of the cervix

Purpose: This study was undertaken to evaluate clinical and pathologic findings that predicted pelvic lymph node metastasis and parametrial and vaginal involvement in patients with stage IB carcinoma of the cervix. Methods: 71 patients with diagnosis of stage IB (FIGO) cervical cancer were prospectively studied from December 1997 to August 2002. The patient's age, clinical stage (IB1 or IB2), histological classification, grade of differentiation, tumor volume, and lymphatic vascular space invasion (LVSI) were evaluated. Statistical methods included chi(2) test and Fisher's exact test to evaluate significant differences between the groups. The level of significance was set at p < 0.05. Results: the clinical stage was IB1 in 51 patients (71.8%) and IB2 in 20 patients (28.2%). The histological classification identified squamous cell carcinoma in 60 patients (84.5%) and adenocarcinoma in 11 patients (15.5%). The average tumoral volume was 22.8 &PLUSMN; 8 24.3 cm(3) (0.3-140.0 cm(3)). The tumor was well differentiated (G1) in 8 (11.3%), moderately differentiated (G2) in 40 (56.3%) and poorly differentiated in 23 (32.4%) of the cases. The presence of LVSI was detected in 14 patients (19.7%) and was associated with pelvic lymph node metastasis and vaginal and parametrial involvement (p = 0.002, p = 0.001 and p < 0.001; respectively). The average number of positive pelvic lymph nodes was significantly higher in the patients with LVSI compared with patients without LVSI (2.47 +/- 2.8 vs. 0.33 +/- 0.74; p = 0.001). There was no association of age, clinical stage, histological classification, grade of differentiation or tumor volume with pelvic lymph node metastasis and vaginal and parametrial involvement. Conclusion: the presence of LVSI is significantly associated with pelvic lymph node metastasis and vaginal and parametrial involvement in patients with stage IB cervical carcinoma.

Effectiveness and safety of a new vaginal misoprostol product specifically labeled for cervical ripening and labor induction

Objective. The purpose of this study was to evaluate the effectiveness and safety of misoprostol in two different formulations: vaginal tablets of 25 mu g and one-eighth of a 200-mu g oral tablet, also administered intravaginally, for cervical ripening and labor induction of term pregnancies with an indication for that. Methods. A single-blind, randomized, controlled clinical trial was carried out in 120 pregnant women who randomly received one of the two formulations. The main dependent variables were mode of delivery, need for additional oxytocin, time between beginning of induction and delivery, perinatal results, complications, and maternal side effects. Student's t, Mann-Whitney, chi(2), Fisher's Exact, Wilcoxon and Kolmogorov-Smirnoff tests, as well as survival analysis, were used in the data analysis. Results. There were no significant differences between the groups in terms of general characteristics, uterine contractility, and fetal well-being during labor, cesarean section rates, perinatal outcomes, or maternal adverse events. The mean time between the beginning of cervical ripening and delivery was 31.3 h in the vaginal tablet group and 30.1 h in the oral tablet group, a difference that was not statistically significant. Conclusion. The results showed that the 25-mu g vaginal tablets of misoprostol were as effective and safe for cervical ripening and labor induction as the dose-equivalent fraction of 200-mu g oral tablets.

Effect of total abdominal hysterectomy on ovarian blood supply in women of reproductive age

Objective. The purpose of this study was to evaluate the effect of total abdominal hysterectomy on ovarian blood supply using transvaginal color Doppler ultrasonography in women of reproductive age. Methods. This prospective study included 61 women aged 40 years or younger who were divided into 2 groups: group 1, comprising 31 patients who underwent total abdominal hysterectomy (TAH), and group 2, comprising 30 women with no abnormalities. Inclusion criteria included normal ovarian function at baseline, with basal follicle-stimulating hormone levels of less than 15 mUI/mL, normal body weight, no tobacco use, and no history of laparotomy or ovarian disease. Ovarian arterial blood supply by determination of the pulsatility index (PI) on Doppler analysis and ovarian volume on transvaginal ultrasonography were assessed at baseline and at 6 and 12 postoperative months. The Student t test, profile analysis, and Friedman and Mann-Whitney tests were used in the statistical analysis of data. Results. Statistical analysis of baseline data revealed that both groups were homogeneous. At months 6 and 12, greater ovarian volumes and lower PI values were observed in patients who underwent TAH (P < .05). By the end of the study, in 8 of the 31 patients who underwent TAH (25.5%), benign ovarian cysts were observed. in the control group, all the parameters studied remained unchanged. Conclusions. The reduced PI values observed on Doppler ultrasonography suggested a decrease in the resistance flow in the ovarian arteries in women of reproductive age who underwent TAH.
