Abstract
OBJECTIVE Vulvodynia (VVD) is a frequent and harrowing condition for which diagnosis and management remain insufficient. Our study aimed to describe and compare vulvovaginal signs and symptoms of Brazilian women with VVD and controls and describe previous medical assessment, past treatments, and vulvar pain relief among women with VVD. METHODS This cross-sectional descriptive study included Brazilian women with (n = 151) and without VVD (n = 106). All women were assessed for vaginal infection, vulvar pain intensity by means of a cotton swab test based on a numerical rate scale, and answered the Female Sexual Function Index questionnaire and a structured instrument about current vulvar symptoms. Previous treatments were assessed in the VVD group, and vulvar pain relief achieved with previous treatments was qualified through a 4-point Likert scale. RESULTS Volunteers were mainly White, with mean age of 30 years. Vulvovaginal signs and symptoms were significantly more frequent in women with VVD (p < .05), and vulvar pain duration was 5.8 (±4) years. More than 50% consulted with three or more physicians, and 49% remained without a conclusive diagnosis. Previous diagnosis and treatment of vulvovaginal infection were often reported by women with VVD. Most of the tried prescriptions were self-reported as providing only low vulvar pain relief. CONCLUSIONS Prolonged duration of vulvar pain, multiple visits to health care professionals, and poor relief of pain are common aspects in the clinical history of women with VVD. In addition to pain, vulvar fissure, edema, erythema, vaginal discharge, and foul odor are common and should be considered to avoid misdiagnosis. Appropriate treatments to VVD are still poorly reported.

Abstract
OBJECTIVE To identify the factors associated with the prescription of vaginal pessaries (VPs) as a conservative treatment for pelvic organ prolapse (POP). METHODS A cross-sectional study was performed during two annual urogynecology and general obstetrics and gynecology meetings in 2017 (São Paulo, SP, Brazil). A 19-item deidentified questionnaire regarding experiences and practices in prescribing VPs for POP patients was distributed among gynecologists. Our primary outcome was the frequency of prescribing VPs as a conservative treatment for POP. The reasons for prescribing or not prescribing VPs were also investigated. Univariate and multivariate analyses with crude and adjusted odds ratios (ORs) were performed for variables associated with the prescription of pessaries. RESULTS Three hundred forty completed surveys were analyzed. Half of the respondents (53.53%) were between 30-49 years old; most of them were female (73.53%), were from the Southeast Region (64.12%), were trained in obstetrics and gynecology (80.24%) or urogynecology (61.18%) and worked in private offices (63.42%). More than one-third (36.48%) attended four or more POP cases/week, and 97.65% (n=332) had heard or knew about VPs for POP; however, only 47.06% (n=160) prescribed or offered this treatment to patients. According to the multivariate analysis, physicians aged 18-35 years (OR=1.97[1.00-3.91]; p=0.04), those who participated in a previous urogynecology fellowship (OR=2.34[1.34-4.09]; p<0.01), those with relatively high volumes of POP cases (4 or +) (OR=2.23[1.21-4.47]; p=0.01) and those with PhD degrees (OR=2.75[1.01-7.54]; p=0.05) prescribed more pessaries. CONCLUSIONS Most gynecologists did not prescribe VPs. Younger physician age, participation in a previous urogynecology fellowship, a PhD degree, and a relatively high volume of POP cases were associated with increased VP prescription rates.

Abstract
PROBLEM A wide variety of mediators are involved in inflammatory processes. However, the identity of those participating in vaginal immune responses has not been established. We correlated extracellular matrix metalloproteinase inducer (EMMPRIN), matrix metalloproteinase-8 (MMP-8), hyaluronan (HA), hyaluronidase-1 (Hyal-1), human β-defensin-2 (hBD2), and neutrophil gelatinase-associated lipocalin (NGAL) concentrations with the extent of leukocyte infiltration into the vagina and suggest their participation in vaginal inflammation. METHODS OF STUDY Vaginal fluid was obtained from 233 women seen at the outpatient clinic in the Department of Obstetrics and Gynecology at Campinas University, Brazil. The magnitude of vaginal inflammation was determined by the leukocyte count on vaginal smears and categorized as no inflammation (0 leukocytes/field), moderate inflammation (1-4 leukocytes/field), and intense inflammation (>4 leukocytes/field). Concentrations of EMMPRIN, MMP-8, HA, Hyal-1, hBD2, and NGAL were determined in vaginal fluid by ELISA. RESULTS EMMPRIN, MMP-8, HA, hBD2, and NGAL concentration increased with elevated leukocyte numbers (P < 0.05), while Hyal-1 did not. EMMPRIN concentrations were correlated with HA and MMP-8 levels. CONCLUSION EMMPRIN, MMP-8, HA, β-defensin, and NGAL are elevated in women with vaginal inflammation.

Abstract
To determine the frequency of abnormal vaginal flora and bacterial vaginosis (BV) in female sex workers (FSW) and the association between douching and vaginal microflora imbalance, a cross-sectional study enrolled 94 users and 61 non-users of vaginal douching. The social-demographic and sexual profile of these women was obtained and their abnormal vaginal flora, BV, vaginal candidiasis, trichomoniasis and cytolitic vaginosis on blinded samples were identified by Gram stain. A stepwise multivariate regression determined the risk of development of vaginal microflora imbalance. Prevalence of abnormal flora, BV, candidiasis, trichomoniasis and cytolytic vaginosis in the entire FSW was 75.5%, 51.0%, 5.1%, 0.64% and 1.9%, respectively. There were no significant differences in these findings between users and non-users of vaginal douching. Regression analysis did not identify any increased risk for altered vaginal flora or BV in vaginal douche users. In conclusion, vaginal douching did not increase the rate of these alterations in FSW.

Effectiveness of complementary pain treatment for women with deep endometriosis through Transcutaneous Electrical Nerve Stimulation (TENS): randomized controlled trial. Eur J Obstet Gynecol Reprod Biol 2015; 194:1-6. [PMID: 26319650 DOI: 10.1016/j.ejogrb.2015.07.009] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2015] [Revised: 07/03/2015] [Accepted: 07/23/2015] [Indexed: 12/11/2022]
Abstract
OBJECTIVE Evaluate TENS effectiveness as a complementary treatment of chronic pelvic pain and deep dyspareunia in women with deep endometriosis. STUDY DESIGN This randomized controlled trial was performed in a tertiary health care center, including twenty-two women with deep endometriosis undergoing hormone therapy with persistent pelvic pain and/or deep dyspareunia. This study was registered in the Brazilian Record of Clinical Trials (ReBEC), under n RBR-3rndh6. TENS application for 8 weeks followed a randomized allocation into two groups: Group 1 - acupuncture-like TENS (Frequency: 8Hz, pulse duration: 250μs) - VIF (n=11) and Group 2 - self-applied TENS (Frequency: 85Hz, pulse duration: 75μs) (n=11). The intensity applied was "strong, but comfortable". We evaluated patients before and after treatment by the use of the Visual Analogue Scale, Deep Dyspareunia Scale and Endometriosis Quality of Life Questionnaire. We used the Wilcoxon and Mann-Whitney tests to compare before and after treatment conditions. RESULTS Despite the use of hormone therapy for 1.65±2.08 years, the 22 women with deep endometriosis sustained pelvic pain complaints (VAS=5.95±2.13 and 2.45±2.42, p<.001) and/or deep dyspareunia (DDS=2.29±0.46 and 1.20±1.01, p=.001). We observed significant improvement for chronic pelvic pain, deep dyspareunia and quality of life by the use of TENS. Both application types of TENS were effective for improving the evaluated types of pain. CONCLUSIONS Both resources (acupuncture-like TENS and self-applied TENS) demonstrated effectiveness as a complementary treatment of pelvic pain and deep dyspareunia, improving quality of life in women with deep endometriosis regardless of the device used for treatment.

Abstract
Vaginal glycogen is degraded by host α-amylase and then converted to lactic acid by Lactobacilli. This maintains the vaginal pH at ≤4.5 and prevents growth of other bacteria. Therefore, host α-amylase activity may promote dominance of Lactobacilli. We evaluated whether the α-amylase level in vaginal fluid is altered in women with bacterial vaginosis (BV) and vulvovaginal candidiasis (VVC) and whether its concentration was associated with levels of lactic acid isomers and host mediators. Vaginal fluid was obtained from 43 women with BV, 50 women with VVC, and 62 women with no vulvovaginal disorders. Vaginal fluid concentrations of α-amylase, secretory leukocyte protease inhibitor (SLPI), hyaluronan, hyaluronidase-1, β-defensin, and elafin were measured by enzyme-linked immunosorbent assay (ELISA). Vaginal concentrations of neutrophil gelatinase-associated lipocalin (NGAL), matrix metalloproteinase (MMP) 8, and d- and l-lactic acid levels in these patients were previously reported. The median vaginal fluid α-amylase level was 1.83 mU/mL in control women, 1.45 mU/mL in women with VVC, and 1.07 mU/mL in women with BV. Vaginal levels of α-amylase were correlated with d-lactic acid (P = .003) but not with l-lactic acid (P > .05) and with SLPI (P < .001), hyaluronidase-1 (P < .001), NGAL (P = .001), and MMP-8 (P = .005). The exfoliation of glycogen-rich epithelial cells into the vaginal lumen by hyaluronidase-1 and MMP-8 may increase glycogen availability and promote α-amylase activity. The subsequent enhanced availability of glycogen breakdown products would favor proliferation of Lactobacilli, the primary producers of d-lactic acid in the vagina. Concomitant production of NGAL and SLPI would retard growth of BV-related bacteria.

Abstract
OBJECTIVE Neutrophil gelatinase-associated lipocalin (NGAL) is a component of innate immunity that prevents iron uptake by microorganisms. We evaluated whether NGAL was present in vaginal fluid and whether concentrations were altered in women with bacterial vaginosis (BV) or vulvovaginal candidiasis (VVC). METHODS Vaginal secretions from 52 women with VVC, 43 with BV, and 77 healthy controls were assayed by enzyme-linked immunosorbent assay for NGAL and for concentrations of L-lactic acid. RESULTS The median concentration of NGAL in vaginal fluid was significantly higher in control women (561 pg/mL) than in women with BV (402 pg/mL; P = .0116) and lower in women with VVC (741 pg/mL; P = .0017). Median lactic acid levels were similar in controls (0.11 mmol/L) and women with VVC (0.13 mmol/L) and were lower in women with BV (0.02 mmol/L; P < .0001). The NGAL and lactic acid concentrations were highly correlated (P < .0001). CONCLUSION A decrease in Lactobacilli and/or lactic acid plus the absence of leukocytes results in lower vaginal NGAL levels that might facilitate the growth of bacteria associated with BV.

Abstract
OBJECTIVE Do metabolites in vaginal samples vary between women with different vaginal disorders. DESIGN Cross-sectional study. SETTING Campinas, Brazil. SAMPLE Seventy-seven women (39.9%) with no vaginal disorder, 52 women (26.9%) with vulvovaginal candidiasis (VVC), 43 women (22.3%) with bacterial vaginosis (BV), and 21 women (10.9%) with cytolytic vaginosis (CTV). METHOD Concentrations of D- and L-lactic acid, extracellular matrix metalloproteinase inducer (EMMPRIN), and matrix metalloproteinase-8 (MMP-8), and the influence of Candida albicans on EMMPRIN production by cultured vaginal epithelial cells, were determined by enzyme-linked immunosorbent assay (ELISA). Associations were determined by the Mann-Whitney U-test and by Spearman's rank correlation test. MAIN OUTCOME MEASURES Metabolite levels and their correlation with diagnoses. RESULTS Vaginal concentrations of D- and L-lactic acid were reduced from control levels in BV (P < 0.0001); L-lactic acid levels were elevated in CTV (P = 0.0116). EMMPRIN and MMP-8 concentrations were elevated in VVC (P < 0.0001). EMMPRIN and L-lactic acid concentrations (P ≤ 0.008), but not EMMPRIN and D-lactic acid, were correlated in all groups. EMMPRIN also increased in proportion with the ratio of L- to D-lactic acid in controls and in women with BV (P ≤ 0.009). Concentrations of EMMPRIN and MMP-8 were correlated in controls and women with VVC (P ≤ 0.0002). Candida albicans induced EMMPRIN release from vaginal epithelial cells. CONCLUSIONS Vaginal secretions from women with BV are deficient in D- and L-lactic acid, women with VVC have elevated EMMPRIN and MMP-8 levels, and women with CTV have elevated L-lactic acid levels. These deviations may contribute to the clinical signs, symptoms, and sequelae that are characteristic of these disorders.

Abstract
OBJECTIVE To evaluate vaginal microbiological and functional aspects in women with and without premature ovarian failure (POF) and the relationship with sexual function. METHODS A cross-sectional study of 36 women with POF under hormonal therapy who were age-matched with 36 women with normal gonadal function. The vaginal tropism was assessed through hormonal vaginal cytology, vaginal pH and vaginal health index (VHI). Vaginal flora were assessed by the amine test, bacterioscopy and culture for fungi. Sexual function was evaluated through the questionnaire Female Sexual Function Index (FSFI). RESULTS Women in both groups were of similar age and showed similar marital status. The two groups presented vaginal tropic scores according to the VHI but the tropism was worse among women in the POF group. No difference was observed with respect to hormonal cytology and pH. Vaginal flora was similar in both groups. Women with POF showed worse sexual performance with more pain and poorer lubrication than women in the control group. The VHI, the only parameter evaluated showing statistical difference between the groups, did not correlate with the domains of pain and lubrication in the FSFI questionnaire. CONCLUSION These findings suggest that the use of systemic estrogen among women with POF is not enough to improve complaints of lubrication and pain despite conferring similar tropism and vaginal flora. Other therapeutic options need to be evaluated.

Abstract
BACKGROUND The repair of the immature squamous epithelium following HPV infection may mimic HSIL in adolescent women. AIM to study the utility of p16 INK4a and Ki-67 in diagnosis of cervical squamous lesions in adolescents and young adults. MATERIALS AND METHODS In a cross-sectional study, the evaluation of p16 INK4a and Ki-67 immunohistochemistry was performed on 72 cervical biopsies of adolescents and young adults women diagnosed as negative for malignancy and intraepithelial lesion (NML) (n = 18) or positive for low grade (LSIL) (n = 31) and high grade (HSIL) (n = 23) squamous intraepithelial lesions in two references services in Fortaleza-Brazil. Data was evaluated using Fisher's test and Kappa index. RESULTS p16 INK4a was positive in 81% of HSIL, 19% of LSIL and in no NML (P < 0.0001). Ki-67 was positive in 74%, 32% and 5.5% of HSIL, LSIL and NML, respectively. p16 INK4a and Ki-67 in the diagnosis of HSIL showed high sensitivity and negative predictive value. Kappa index was very good for p16 INK4a (k = 0.72). CONCLUSIONS In adolescents and young adults p16 INK4a alone or with Ki-67 represents important tool to reduce mistaken diagnosis of HSIL and to avoid overtreatment.

Abstract
OBJECTIVES To investigate if the participation of Atopobium vaginae, Megasphaera sp. and Leptotrichia sp. in the bacterial community of bacterial vaginosis (BV) is associated with distinct patterns of this condition. METHODS In this cross-sectional controlled study, 205 women with BV and 205 women with normal flora were included. Vaginal rinsing samples were obtained for measuring the levels of pro-inflammatory cytokines and bacterial sialidases. Real-time PCR was used to quantify the BV-associated bacteria and to estimate the total bacterial load using the 16S rRNA. Principal component analysis (PCA) using the measured parameters was performed to compare the BV samples with lower and higher loads of the species of interest. RESULTS Higher bacterial load (p<0.001), levels of interleukin 1-β (p<0.001) and sialidase activity (p<0.001) were associated with BV. Women with BV and higher relative loads of A vaginae, Megasphaera sp. and Leptotrichia sp. presented increased sialidase activity, but unchanged cytokine levels. PCA analysis did not indicate a different pattern of BV according to the loads of A vaginae, Megasphaera sp. and Leptotrichia sp. CONCLUSIONS Greater participation of A vaginae, Megasphaera sp. and Leptotrichia sp. in vaginal bacterial community did not indicate a less severe form of BV; moreover, it was associated with increased sialidase activity.

Abstract
Vulvodynia affects a large number of women worldwide. It is estimated that the prevalence rate of vulvodynia is 16% in women aged 18 to 64 years, resulting in constant demand for specialized medical care, although little therapeutic success is achieved. Furthermore, the cause of this disorder remains unknown and involves different symptoms that are implicated in important chronic vulvar pain with disastrous consequences for the afflicted women. In view of these data, the authors have proposed a bibliographic review of the pathophysiology and treatment of vulvodynia. The aim of this review was to assist in clinical diagnosis and elucidate the multidisciplinary treatment that appears to be associated with a higher success rate in these women. Physical therapy using diverse techniques has an important role in multidisciplinary care, obtaining satisfactory results in the treatment of pelvic floor muscle dysfunction and thus improving the symptoms and quality of life in women with vulvodynia.

Abstract
OBJECTIVE The objective of the study was to evaluate the risk of anal squamous intraepithelial lesions (ASILs) in immunocompetent women with genital squamous intraepithelial lesions (GSILs). STUDY DESIGN This was a cross-sectional study that included 260 immunocompetent women divided into 2 study groups: 1 group included 184 women diagnosed with GSIL by genital colposcopy and biopsy, and the other included 76 controls. All subjects were submitted to anoscopy followed by a biopsy if pertinent. RESULTS Of 184 GSIL women, 32 (17.4%) had ASIL (P<.001). The risk of ASIL was 13.1 times greater for GSIL women when there were 3 or 4 genital sites involved. All cases of high-grade ASIL were found in women with cervical GSILs. Among risk factors, anal intercourse without a condom demonstrated an important association with ASIL (prevalence ratio adjusted for age=2.6). CONCLUSION There seems to be a strong association between ASIL and multicentric GSIL. Another factor related to ASIL was the practice of unprotected anal intercourse.

Abstract
OBJECTIVE To evaluate whether the use of "breathable" panty liners (BPLs) alters the normal vaginal flora, increases the incidence of bacterial vaginosis and/or vaginal candidiasis, or causes vulvar irritation. METHODS A randomized controlled trial assessed the vaginal ecosystem of women without complaints of vaginal discharge. The study group (n=53) wore BPLs for 10-12 hours each day for 75 consecutive days, whereas the control group (n=54) wore only their usual underwear. At each of 6 visits during 3 menstrual cycles, participants underwent gynecologic examination with colposcopic evaluation and pH measurement, in addition to assessment of vaginal microbial flora, intensity of inflammatory processes, and presence of vaginal candidiasis/bacterial vaginosis in Gram-stained smears. RESULTS After 75 consecutive days of BPL use, 40/44 (90.9%) and 42/44 (95.5%) women reported no complaints of vaginal discharge or vulvar itching/burning, respectively. There was no significant difference between the study group and the control group with regard to positive vaginal fungus cultures (5/44 [11.4%] vs 8/50 [16.0%]; P=0.7848) or bacterial vaginosis (3/44 [6.8%] vs 2/50 [4.0%]; P=0.7974) at the end of the study period. CONCLUSION After 75 days of BPL use, there was no significant increase in vulvovaginal candidiasis, bacterial vaginosis, vulvovaginal irritation, or vulvovaginal inflammation.

Contemporary perspectives on vaginal pH and lactobacilli. Am J Obstet Gynecol 2011; 204:120.e1-5. [PMID: 20832044 DOI: 10.1016/j.ajog.2010.07.010] [Citation(s) in RCA: 125] [Impact Index Per Article: 9.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2010] [Revised: 05/21/2010] [Accepted: 07/06/2010] [Indexed: 11/18/2022]
Abstract
Ever since the pH of the vagina was found to be much more acidic than blood and interstitial fluids, a belief going back more than a century has persisted that the vagina is protected from pathogenic organisms by the high level of hydronium ions present. A corollary of this belief is that the pH of the vagina and antipathogen activity is due to colonizing Lactobacilli. Unfortunately, this dogma lacks empirical research support. The vaginal pH is determined by the interplay between vaginal physiological processes and microbiology. An acidic vaginal pH and Lactobacilli are components of multiple defense mechanisms active in protection against infection in the lower female genital tract.

Hyaluronan in vaginal secretions: association with recurrent vulvovaginal candidiasis. Am J Obstet Gynecol 2009; 201:206.e1-5. [PMID: 19646572 DOI: 10.1016/j.ajog.2009.05.010] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2009] [Revised: 03/28/2009] [Accepted: 05/10/2009] [Indexed: 11/19/2022]
Abstract
OBJECTIVE We evaluated whether vaginal concentrations of hyaluronan were altered in women with recurrent vulvovaginal candidiasis (RVVC). STUDY DESIGN Lavage samples from 17 women with acute RVVC, 27 women who were receiving a maintenance antifungal regimen, and 24 control women were tested for hyaluronan and interleukin (IL)-6, IL-12, and IL-23 by enzyme-linked immunosorbent assay. RESULTS Median vaginal hyaluronan concentrations were 33.8 ng/mL (range, 21.6-66.3 ng/mL) in women with acute RVVC, 15.0 ng/mL (range, 11.2-50.6 ng/mL) in women who were receiving maintenance therapy, and 4.2 ng/mL (range, 3.6-12.0 ng/mL) in control subjects (P </= .02). The vaginal hyaluronan concentration was 27.4 ng/mL (range, 15.4-37.7 ng/mL) when Candida was detected by microscopy and 9.5 ng/mL (range, 7.7-14.6 ng/mL) in microscopy-negative cases (P = .0354). Elevated hyaluronan levels were associated with itching plus burning (40.7 ng/mL) or itching plus discharge (42.1 ng/mL), as opposed to itching only (6.2 ng/mL; P = .0152). Hyaluronan and IL-6 levels were correlated (P = .0009). CONCLUSION Hyaluronan release is a component of the host response to a candidal infection and may contribute to symptoms.

Abstract
The genital mechanisms of defense are not well understood and are therefore ignored during therapy. This fact results in a great number of cases of treatment failure. The mucosa is an important protective factor of the genital female system, through self-defense mechanisms, and secretor antibodies (immunoglobulin A). The lymphoid tissue exerts protective anti-inflammatory activity, besides inhibiting microorganism adherence, neutralizes viruses and toxins and stabilizes the mucosal flora. Although certain microorganisms, such as viruses and fungus, are controlled by cellular immunity, secretory IgA can also exert an important role in the control of these agents.

Abstract
OBJECTIVE To evaluate associations between polymorphisms in the gene coding for mannose-binding lectin (MBL) and the diagnosis of acute or recurrent vulvovaginal candidiasis and bacterial vaginosis METHODS Women at two outpatient clinics in Brazil filled out a questionnaire and were examined for the presence of vulvovaginal candidiasis or bacterial vaginosis. A buccal swab was blindly tested for codons 54 and 57 MBL2 gene polymorphisms by polymerase chain reaction and endonuclease digestion. RESULTS A total of 177 women were enrolled. Vulvovaginal candidiasis was identified in 78 (44.1%) women, 33 (18.6%) had bacterial vaginosis, and 66 (37.3%) were normal controls. Recurrent vulvovaginal candidiasis was present in 50 (64.1%) of the women with vulvovaginal candidiasis; 20 (60.6%) of the bacterial vaginosis patients had recurrent disease. Vulvovaginal candidiasis was associated with white race (P=.007), bacterial vaginosis was associated with nonwhite race (P=.05), and both were associated with a history of allergy (P< or =.02) and having sexual intercourse at least three times a week (P<.001). Carriage of the variant MBL2 codon 54 allele B was more frequent in women with recurrent vulvovaginal candidiasis (25.0%) than in the women with acute vulvovaginal candidiasis (17.9%) or controls (10.6%) (P=.004). Allele B was also more prevalent in women with recurrent bacterial vaginosis (22.5%) than in those with acute bacterial vaginosis (0%) (P=.009). The MBL2 codon 57 polymorphism was infrequent and not associated with vulvovaginal candidiasis or bacterial vaginosis. CONCLUSION The incidence of vulvovaginal candidiasis and bacterial vaginosis differs by ethnicity in Brazilian women. The MBL2 codon 54 gene polymorphism is associated with both recurrent vulvovaginal candidiasis and recurrent bacterial vaginosis.

Abstract
OBJECTIVES The objectives were to assess the prevalence of high-risk HPV in the male sexual partners of women with HPV-induced lesions, and correlate it with biopsies guided by peniscopy. STUDY DESIGN Fifty-four asymptomatic male sexual partners of women with low-grade squamous intra-epithelial lesions (LSIL) associated with high-risk HPV were examined between April 2003 and June 2005. The DNA-HPV was tested using a second-generation hybrid capture technique in scraped penile samples. Peniscopy identified acetowhite lesions leading to biopsy. RESULTS High-risk HPV was present in 25.9% (14 out of 54) of the cases. Peniscopy led to 13 biopsies (24.07%), which resulted in two cases of condyloma, two cases of intra-epithelial neoplasia (PIN) I, one case of PIN II, and eight cases of normal tissue. The high-risk HPV test demonstrated 80% sensitivity, 100% specificity, 100% positive predictive value, and 88.9% negative predictive value for the identification of penile lesions. There was a greater chance of finding HPV lesions in the biopsy in the positive cases of high-risk HPV with abnormal peniscopy (p=0.007); OR=51 (CI 1.7-1527.1). CONCLUSION Among asymptomatic male sexual partners of women with low-grade intra-epithelial squamous lesions, those infected by high-risk HPV have a higher chance of having abnormal penile tissue compared with male partners without that infection.

Abstract
Diagnosis of vaginal discharge is frequently performed in an empirical way, leading to inadequate treatment. This study tested the accuracy of a self-collection kit for microbiological study of the vaginal content. One hundred and forty-two women of Family Health Program units in Niterói and Piraí cities were enrolled in order to have their vaginal content studied. A brief explanation and a self-collection kit were provided in order to sample the vaginal content. The self-collection kit was composed of one empty plastic tube, two glass slides, a long handle cytobrush, an identification card and guideline notes. The vaginal sample was applied on the glass slides by the women and stained by Gram technique. A second sampling was done by the medical personnel. The microbiological diagnosis in a blinded analysis was made under optical microscopy. A validation diagnosis test was done taking the medical collection results as a gold standard. A total of 106 women had followed the protocol and were included in the study. Microbiological analysis was unsatisfactory in 12 cases (6 cases of self-collection material and 6 cases of medical collection). The microbiological analyses in the self-collection and in the medical collection material were respectively: bacterial vaginosis in 21.7% and 17.9%, non bacillar flora in 10.3% and 11.3%, vaginal trichomoniasis in 5.66% and 5.6%, candidiasis in 3.78% and 2.8% and a normal microbiota in 52.8% and 56.6%. The Kappa coefficient suggested a "very good correlation" of the microbiological results between the two methods of collection (K=0.7945). The self-collection kit provides samples for microbiological analysis of the vaginal microbiota as good as medical collection.

Abstract
AIM To investigate the association between chronic periodontitis (CP) and pre-maturity in a group of Brazilian pregnant women from the State of São Paulo. MATERIALS AND METHODS One hundred and twenty-four women were investigated consecutively in a cross-sectional study, between December 2003 and May 2005. Sixty-eight women had pre-term labour (PTL) and 56 had term labour. A periodontal examination was carried out to identify the presence of CP. Statistical analysis used the Fisher's exact test or chi(2) for the discrete variables and the Mann-Whitney test for the non-parametric variables. Odds ratio (OR) was calculated with a 95% confidence interval (CI), to evaluate the relation between CP and pre-maturity. RESULTS Periodontal indicators, such as clinical attachment loss (p<0.0001) and bleeding on probing (p=0.012), were observed more in the PTL group. The presence of CP increased the risk for PTL (OR: 4.7, 95% CI: 1.9-11.9), pre-term birth (PTB; OR: 4.9, 95% CI: 1.9-12.8) and low birth weight (<2500 g; OR: 4.2, 95% CI: 1.3-13.3). The pregnant women with PTL presented low levels of schooling (p=0.029) and the lowest number of pre-natal appointments (p=0.0001) when compared with those with term labour. CONCLUSION CP is strongly associated with PTL, PTB and low birth weight in a group of Brazilian pregnant women. These data point to the necessity of regularly investigating CP during pregnancy.

Abstract
To determine whether there is an association between atopy and recurrent vaginal candidiasis (RVC) and to evaluate the type-2 immune response in patients with RVC. Evaluation of immediate hypersensitivity skin tests to aeroallergens, measurement of total IgE and Candida albicans specific IgE and levels of IL-5 in 44 women with RVC and 26 with sporadic vaginal candidiasis (SVC). Statistical analyses were performed by Mann-Whitney test and chi(2) test with Yates correction. History of atopy (68%) and positive skin test (42%) were higher (P < 0.05) in RVC than in patients with SVC. No significant difference was found in total IgE, C. albicans specific IgE and IL-5 levels. There was a strong association between atopy and RVC, but type-2 immune response to C. albicans antigen was absent or similar in the two groups of patients.

Abstract
OBJECTIVE To determine and to compare the levels of secretory immunoglobulin A in samples of colostrum and milk of mothers of term and preterm neonates. MATERIAL AND METHODS The levels of secretory immunoglobulin A of 10 mothers of term neonates and 10 mothers of preterm neonates were determined from 5 mL of colostrum or milk collected on the 1st, 4th, 10th and 15th days of the puerperal period, using the radial immunodiffusion technique. We employed anamnesis, as well as physical and gynecological exams in women in the puerperal period. All the patients were attended at the Januário Cicco Maternity College. RESULTS The secretory immunoglobulin A levels were significantly higher in the colostrum and milk of mothers of preterm neonates when compared with the levels found in colostrum and milk of mothers of term neonates (Mann-Whitney test, p<0.0001). There was a significant decline in the secretory immunoglobulin A levels of the colostrum and milk of the mothers of term and preterm neonates during the four periods (Kruskal-Wallis test, p<00001). CONCLUSIONS The secretory immunoglobulin A levels in colostrum and milk of mothers of preterm neonates were significantly higher than in the mothers of term neonates, demonstrating immunological adaptation in preterm neonate breast-feeding.

Abstract
OBJECTIVE To investigate the prevalence of bacterial vaginosis (BV) and abnormal bacterial vaginal flora in an infertile population and correlate with cervical cytokine production and in vitro fertilization (IVF) outcome. STUDY DESIGN In a blinded study, 331 asymptomatic IVF patients were evaluated for BV, abnormal vaginal flora and cervical cytokine production (interleukin 1 beta [IL-1 beta] and IL-8) on the day of oocyte retrieval. All patients received tetracycline prophylaxis at the time of oocyte retrieval. RESULTS BV was identified in 4.2% (14/331) of the patients. Patients with idiopathic infertility were more likely to have BV than were women with other causes of infertility (P = .02 vs. male factor, P = .03 vs. tubal factor and P < .01 vs. endometriosis-associated infertility). Patients with abnormal vaginal flora had higher cervical IL-1 beta and IL-8 cytokine levels as compared to patients with normal vaginal flora. IL-1 beta and IL-8 levels in the study subjects correlated highly. No differences were detected in IVF outcome parameters based on the vaginal flora determined at the time of retrieval. CONCLUSION Abnormal vaginal flora, including that causing BV, is associated with elevated cervical levels of IL-1 beta and IL-8. The induction of proinflammatory cytokines by an altered vaginal ecosystem may be a previously unrecognized cause of idiopathic infertility.

Abstract
OBJECTIVE Predisposing factors influencing recurrences of bacterial vaginosis (BV) or vaginitis from Candida remain unidentified for most women. As a component of studies to determine host susceptibility factors to genital tract infections in women, we measured expression of the 60-kDa and 70-kDa heat shock proteins (hsp60 and hsp70, respectively) in the circulation of women with or without a history of recurrent BV or candidal vaginitis and with or without a current lower genital tract infection. Heat shock protein expression is associated with a down-regulation of pro-inflammatory immune responses that would inhibit microbial infection. METHOD The investigators measured hsp60 and hsp70, antibodies to these proteins, the pro-inflammatory cytokine tumor necrosis factor-alpha (TNF-alpha), and the anti-inflammatory cytokine interleukin-10 (IL-10) in sera by ELISA. The study population consisted of 100 women who attended a gynecology clinic in Campinas, Brazil. Of those, 55 had a history of recurrent vulvovaginitis (RV), while 45 were controls with no such history. Only women who were asymptomatic for at least 1 month were studied. RESULTS Although all were asymptomatic, clinical and microbiological examination revealed that five of the women with a history of RV and two controls had a current candidal vaginal infection; 16 RV patients and 12 controls had BV; and six RV patients had both BV and candidiasis. Twenty-eight RV patients and 31 controls had no clinical or microbiological detectable vaginal infection. Among the RV patients, hsp60 and hsp70 were more prevalent in those with current BV (40.9% and 50.0%, respectively) or a candidal infection (45.5% and 54.5%) than in women with no current infection (21.4% and 17.9%). In the women with no history of RV, BV was not associated with a high prevalence of hsp60 (8.3%) or hsp70 (8.3%). Interleukin-10 and TNF were not more prevalent in vaginitis patients or controls with a current candidal infection or BV than in uninfected subjects. CONCLUSION The high prevalence of circulating hsp60 and hsp70 in women with a history of RV and current BV or vaginal candidiasis, but not in women with no history of RV, suggests that differences in heat shock protein induction may be related to susceptibility to recurrent vaginal infections.

Abstract
OBJECTIVES The aim of this study was to establish the prevalence of cervicovaginal infections in normal third-trimester pregnant women and evaluate the accuracy of clinical diagnosis. METHOD A total of 328 pregnant women were followed at the Prenatal Outpatient Clinic of the Department of Obstetrics and Gynecology at the School of Medical Sciences, Universidade Estadual de Campinas (UNICAMP), Brazil, from October 1991 to February 1993. The clinical diagnosis was based on the characteristics of the vaginal discharge, and the etiological diagnosis was based on bacterioscopy of the vaginal secretion and direct immunofluorescence for Chlamydia trachomatis. The data were analyzed statistically, determining the sensitivity, specificity, and positive and negative predictive value of the clinical diagnosis related to the laboratory diagnosis of the different infections. RESULTS The prevalence of infection was 39.6% (Candida albicans, 19.2%; bacterial vaginosis, 9.5%; intermediate vaginal flora, 6.7%; Chlamydia trachomatis, 2.1%; and vaginal trichomoniasis, 2.1%). The accuracy of clinical diagnosis was low, with sensitivity between 50% and 65% and specificity around 60%, with the exception of trichomoniasis, which showed a sensitivity of 100% and chlamydia, with a sensitivity of 0% and a specificity of 100%. CONCLUSION The accuracy of the clinical diagnosis of infections was low, specifically with respect to the positive predictive value. The results demonstrate the need for specific testing of cervicovaginal infections at prenatal visits. Reliance on simple vaginal examination results in a low yield for detection of vaginal infections.

Abstract
A fine needle aspiration biopsy (FNAB) device was designed to utilize a steel spring located between the syringe and its plunger, which exerts a constant negative pressure (auto-vacuum). In 43 rats inoculated with breast tumour cells, the technique was compared with the standard procedure of FNAB (21 Sp1 and 22 Walker256 carcinosarcoma). Malignant cells were cytologically confirmed in all cases. Sufficient material was obtained in 95% of FNAB by auto-vacuum system versus 86% by standard technique. The superior results obtained with the auto-vacuum system was seen for both soft and hard tumours.
