Vaginal necrosis: A rare late toxicity after radiation therapy.

Vaginal necrosis is a late radiation tissue injury with serious morbidity complications. It is rare, and its incidence is not well assessed in prospective trials. Patient comorbidities and radiation dose can significantly increase the risk. As treatment of gynecologic malignancies often involve a multidisciplinary approach, timely diagnosis and appropriate management by physicians of the team are crucial. Untreated vaginal necrosis can lead to infection, hemorrhage, necrosis-related fistulation to the bladder or rectum, perforation, and death. In this review, we describe the pathophysiology of vaginal necrosis, its clinical course, and management options.

Vaginal douching in Zambia: a risk or benefit to women in the fight against cervical cancer: a retrospective cohort study.

BACKGROUND: Cervical cancer was the most commonly diagnosed cancer and the leading cause of cancer related deaths in 2013 among women in Zambia. We determined factors associated with vaginal douching with any solution other than water and examined its role as a risk factor for abnormal cervical lesions among Zambian women. METHODS: We conducted a retrospective cohort study using data from the Cervical Cancer Prevention Program in Zambia among 11,853 women (15 years or older) who had screened for cervical cancer from 6 provinces of Zambia. Stata version 15 was used to analyze the data. Investigator led stepwise logistic regression was used to estimate adjusted odds ratios and 95% confidence intervals for various characteristics, with vaginal douching with any solution as primary outcome and abnormal cervical lesions as secondary outcome. RESULTS: Douching with any solution other than water was practiced by 8.1% (n = 960) of the study participants. Older women (35-44 and 45 years or older) vs young women (15-24 years old) were less likely to douche with a solution (AOR 0.74; 95% CI: 0.57-0.97, p = 0.027 and AOR 0.65; 95% CI: 0.49-0.87, P = 0.004), respectively, and so were women in informal employment compared to housewives (AOR 0.72; 95% CI: 0.58-0.89, p = 0.002). Odds of douching were higher among women with secondary vs. no formal education (AOR 1.64; 95% CI: 1.15-2.35, P = 0.007), and among women who used condoms sometimes compared to those who never with their regular sexual partners (AOR 1.19; 95% CI: 1.01-1.40, PP = 0.037). About 12.2% of study participants had abnormal cervical lesions. The use of either vinegar, ginger, lemon, salt or sugar solution was associated with increased risk of abnormal cervical lesions (AOR 7.37; 95% CI: 1.43-38.00, p = 0.017) compared to using water. CONCLUSION: We find an association between douching with a solution and a woman's age, educational attainment, occupation and condom use. Vaginal douching with either vinegar, ginger, lemon, salt or sugar solution was associated with increased risk for abnormal cervical lesions. We recommend further research on ever vs never douching and the risk for abnormal cervical lesions.

Effect of vaginal washing before intravaginal dinoprostone insertion for labor induction: A randomized clinical trial.

AIM: Prostaglandins have a dual action of cervical ripening and induction of uterine contraction. This study was designed to compare the effectiveness of vaginal washing just before insertion of intravaginal dinoprostone. METHODS: A randomized controlled trial was conducted at the Zeynep Kamil Women and Children's Health Training and Research Hospital. One hundred and ninety-one women with singleton, term pregnancy who underwent labor induction were randomly assigned to two groups: Group 1 consisted of 95 pregnant women with vaginal washing before intravaginal dinoprostone (Propess system for slow release system of 10 mg of dinoprostone) insertion (study group), and 96 pregnant women constituted the control group who did not undergo vaginal washing before intravaginal dinoprostone insertion. A parallel randomized controlled trial was conducted with an allocation ratio of 1:1 to compare the effectiveness of vaginal washing before intravaginal dinoprostone insertion. RESULTS: The groups had similar mean age, body mass index, gestational age, gravidity, parity and Bishop score before agent insertion (P > 0.05). Duration of dinoprostone kept intravaginally, duration from the beginning of dinoprostone insert vaginally to the active phase of labor and duration from the time of intravaginal dinoprostone insertion to delivery were significantly longer in the control group (P < 0.05). Uterine hyperstimulation rate was significantly higher in study group compared to control group (P < 0.05). Meconium passage, fetal infection and neonatal intensive care unit admission were significantly higher in the control group (P < 0.05). CONCLUSION: Vaginal washing before intravaginal dinoprostone insertion may increase Prostaglandin E2 bioavailability as we found shorter duration and better outcome of labor induction in the present study.

Intravaginal practices are associated with greater odds of high-risk HPV infection in Haitian women.

OBJECTIVE: Haitian women have the highest incidence of cervical cancer within the Western hemisphere. Intravaginal hygiene practices have been linked with human papilloma virus (HPV) infection and cervical dysplasia. These practices, known as 'twalet deba' in Haitian Creole, are common among Haitian women and are performed with various natural and synthetic agents. As part of a community-based participatory research initiative aimed at reducing cervical cancer disparities in rural Haiti, we explored the use of intravaginal agents and their associations with high-risk HPV infection. DESIGN: Community Health Workers recruited 416 women for cervical self-sampling from two neighborhoods within Thomonde, Haiti. Participants were interviewed regarding intravaginal hygiene practices and completed a cervical self-sampling procedure. Cervical samples were analyzed for the presence of high-risk HPV infection. Associations between each intravaginal agent and high-risk HPV infection were examined via univariate logistic regression analyses, as well as via multivariate analyses controlling for sociodemographic factors and concurrent agent use. RESULTS: Nearly all women (97.1%) performed twalet deba, using a variety of herbal and commercially produced intravaginal agents. Approximately 11% of the participants tested positive for high-risk HPV. Pigeon pea and lime juice were the only agents found to be associated with high-risk HPV in the univariate analyses, with women who used these agents being approximately twice as likely to have high-risk HPV as those who did not. Only pigeon pea remained significantly associated with high-risk HPV after controlling for sociodemographic factors and concurrent agent use. CONCLUSION: Two agents, pigeon pea and lime juice, may contribute to risk for HPV infection in this population. Results suggest that in addition to cervical cancer screening interventions, future preventive initiatives should focus on minimizing risk by advocating for the use of less-toxic twalet deba alternatives.

Intravaginal Practices and Prevalence of Sexual and Reproductive Tract Infections Among Women in Rural Malawi.

BACKGROUND: Many women engage in intravaginal practices (IVP) with a goal of improving genital hygiene and increasing sexual pleasure. Intravaginal practices can disrupt the genital mucosa, and some studies have found that IVP increases risk of acquisition of HIV and bacterial vaginosis (BV). Limited prior research also suggests significant associations between IVP, herpes simplex virus type 2 (HSV-2), and high-risk types of human papillomavirus (HPV). METHODS: We examined associations between IVP and HPV, BV, and HSV-2 among 200 women in rural Malawi participating in a clinic-based study on sexual and reproductive tract infections. We calculated prevalence ratios for the associations between frequency and type of IVP and outcomes of HPV, BV, and HSV-2. RESULTS: Intravaginal practices were commonly performed, with 95% of women reporting current use of at least 1 practice. Infections were also frequently detected: Twenty-two percent of the sample had at least 1 high-risk HPV type, 51% had BV, and 50% were HSV-2 seropositive. We observed no significant associations between type of IVP, frequency of IVP, or a combined measure capturing type and frequency of IVP-and any of the infection outcomes. CONCLUSIONS: Although both IVP and our outcomes of interest (BV, HPV, and HSV-2) were common in the study population, we did not detect associations between IVP type or frequency and any of the 3 infections. However, the high prevalence and frequency of IVP may have limited our ability to detect significant associations.

Intravaginal practices and lactobacilli colonization among women in Accra, Ghana.

BACKGROUND: Intravaginal practices may affect the colonization of vaginal flora and lead to vaginal infections due to the potential effects on the vaginal environment. This study investigated the vaginal practices and their possible effects on vaginal lactobacilli flora colonization in women in Accra. METHODS: A cross-sectional, descriptive single-site study was carried out on 141 women assessing medical care at the Obstetrics and Gynaecology Department of the Korle-Bu Teaching Hospital (KBTH) in Accra. Study-relevant information on participants was obtained by means of questionnaire. Vaginal swab samples were collected and processed for laboratory analyses. RESULTS: All the participants (141/141, 100.0 %) indicated they performed intravaginal practices using various methods. Almost half (46.1 %) of these women were between the ages of 25-34 years and 65.0 % were married. Internal douching (82.3 %; p > 0.05) was the commonest practice reported. Other practices such as insertion and wiping with hands and objects, as well as use of locally prepared concoctions and certain commercial products were also reported. The reason most commonly given was for hygienic purpose (83.0 %); a few (10.6 %) did it for sexual satisfaction, while others indicated vaginal tightness (5.7 %) and wound healing (0.7 %) as reasons for their practice. No Lactobacillus sp. was detected in as many as 78.7 % of the sample. Association tests by the Pearson correlation analysis showed strong significant negative correlation (r = -0.954, p < 0.05) between use of traditional herbs/concoction and vaginal lactobacilli colonization; and douching being the least negatively (r = -0.601, p > 0.05) correlated practice. CONCLUSIONS: Vaginal practices were common among the women studied. A more elaborate prospective, case-control study into intravaginal practices and their impact on the health of women in Ghana should be explored.

Vaginal chlorhexidine during labour for preventing maternal and neonatal infections (excluding Group B Streptococcal and HIV).

BACKGROUND: The incidence of chorioamnionitis occurs in between eight and 12 women for every 1000 live births and 96% of cases of chorioamnionitis are due to ascending infection. Following spontaneous vaginal delivery, 1% to 4% of women develop postpartum endometritis. The incidence of neonatal sepsis is 0.5% to 1% of all infants born. Maternal vaginal bacteria are the main agents for these infections. It is reasonable to speculate that prevention of maternal and neonatal infections might be possible by washing the vagina and cervix with an antibacterial agent for all women during labour. Chlorhexidine belongs to the class of compounds known as the bis-biguanides. Chlorhexidine has antibacterial action against a wide range of aerobic and anaerobic bacteria, including those implicated in peripartal infections. OBJECTIVES: To evaluate the effectiveness and side effects of chlorhexidine vaginal douching during labour in reducing maternal and neonatal infections (excluding group B streptococcal and HIV). SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 June 2014), reference lists of retrieved reports and journal letters and editorials. SELECTION CRITERIA: Randomized or quasi-randomized trials comparing chlorhexidine vaginal douching during labour with placebo or other vaginal disinfectant to prevent (reduce) maternal and neonatal infections (excluding group B streptococcal and HIV). DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trial eligibility and quality, extracted and interpreted the data. A third review author analyzed and interpreted the data. The fourth author also interpreted the data. MAIN RESULTS: We included three studies (3012 participants). There was no evidence of an effect of vaginal chlorhexidine during labour in preventing maternal and neonatal infections. Although the data suggest a trend in reducing postpartum endometritis, the difference was not statistically significant (three trials, 3012 women, risk ratio 0.83; 95% confidence interval 0.61 to 1.13).Assessment of the quality of the evidence using GRADE indicated that the levels of evidence for all primary outcomes and one important secondary outcome were low to moderate. AUTHORS' CONCLUSIONS: There is no evidence to support the use of vaginal chlorhexidine during labour in preventing maternal and neonatal infections. There is a need for a well-designed randomized controlled trial using appropriate concentration and volume of vaginal chlorhexidine irrigation solution and with adequate sample size.

Vaginal cleansing practices in HIV infected Zambian women.

Vaginal practices are a variety of behavioral techniques that women use to manage their sexual life and personal hygiene. Women perceive vaginal practices as a beneficial practice. However, vaginal cleansing has been identified as one of the main risk factors for bacterial vaginosis and is potentially implicated in Human Immune Deficiency Virus (HIV) and sexually transmitted infection transmission. This study examined the prevalence of vaginal practices and the types of practices used among a sample of HIV positive women living in Lusaka, Zambia. Over 90% of all women recruited engaged in vaginal practices. Certain practices, such as use of water or soap, were more frequently used for hygiene reasons. Herbs and traditional medicines were mainly used to please sexual partner. Strategies to decrease VP appear urgently needed in the Zambian community.

Intravaginal cleansing among women attending a sexually transmitted infection clinic in Kingston, Jamaica.

OBJECTIVES: Although common worldwide, intravaginal cleansing is associated with poor health outcomes. We sought to describe intravaginal cleansing among women attending a sexually transmitted infection (STI) clinic in Jamaica. METHODS: We examined intravaginal cleansing ("washing up inside the vagina", douching, and products or materials used) among 293 participants in a randomized trial of counselling messages at an STI clinic in Kingston. We focussed on information on intravaginal cleansing performed in the 30 days and three days preceding their baseline study visit. We describe reported cleansing behaviours and used logistic regression to identify correlates of intravaginal cleansing. RESULTS: Fifty-eight per cent of participants reported intravaginal cleansing in the previous 30 days, and 46% did so in the three days before baseline. Among those who cleansed in the previous 30 days, 88% reported doing so for hygiene unrelated to sex, and three-fourths reported generally doing so more than once per day. Soap (usually with water) and water alone were the most common products used for washing; commercial douches or detergents were reported infrequently. Intravaginal cleansing in the three days before the baseline visit was positively associated with having more than one sex partner in the previous three months (adjusted odds ratio [AOR], 1.9; 95% CI, 1.1, 3.2), and negatively associated with experiencing itching in the genital area at baseline (AOR, 0.6; 95% CI, 0.4, 1.0). CONCLUSIONS: A large proportion of women attending STI clinics in Jamaica engage in frequent intravaginal cleansing, indicating a need for clinicians to discuss this topic with them accordingly.

Cervicovaginal self-sampling is a reliable method for determination of prevalence of human papillomavirus genotypes in women aged 20 to 30 years.

Self-sampling by cervicovaginal lavage could be an attractive method to detect high-risk human papillomavirus (hr-HPV) infections to identify women with a risk of cervical precancer. The objective of our study was to use self-sampling for the first time in a cross-sectional approach to determine HPV prevalence and genotype distribution. We evaluated participants' acceptance and laboratory results from self-obtained samples versus endocervical brush samples obtained by gynecologists. To determine the sensitivity of both sampling methods in presumed high- and low-prevalence settings, two groups of women 20 to 30 years of age with (n = 55) and without (n = 101) a recent suspicious cytological smear were compared. Overall, 76% (95% confidence interval [95% CI], 65 to 88) of women with and 40% (95% CI, 30 to 49) of women without a recent suspicious cytological smear tested HPV positive. The prevalences of high-risk HPV strains were 71% (95% CI, 59 to 83) and 32% (95% CI, 22 to 41), respectively, for these two groups. The agreement for hr-HPV between the two sampling methods for women with and without suspicious cytology was 84% (κ = 0.65; 95% CI, 0.44 to 0.86) and 91% (κ = 0.78; 95% CI, 0.64 to 0.92), respectively. Participants rated the user-friendliness of the self-sampling method on a visual analog scale from 0 (easy) to 100 (difficult) with a median of 12. In conclusion, self-sampling by cervicovaginal lavage is a reliable method to determine hr-HPV prevalence and is well accepted by young adult females.

Comparison of natural histories of human papillomavirus detected by clinician- and self-sampling.

New strategies for cervical cancer screening include human papillomavirus (HPV) DNA testing. Using self-testing methods would increase access to testing in both developed and developing countries. The purpose of this study was to compare time-to-clearance of specific HPV types between clinician-collected-lavage (CC-L) and self-collected (SC) sampling in a single cohort. CC-L and SC samples were obtained every 4 months at alternate 2-month windows from 537 women. Eighteen high-risk (HR) HPV and 4 low-risk (LR) HPV were examined. Proportional hazards model was used to compare time-to-clearance between methods for combined HR and for 13 specific HPV types. Prentice-Wilcoxon test was used for within-subject paired comparison. In the independent analysis for combined HR and LR types, no differences were found. For specific types, time-to-clearance for all HPV types examined between CC-L and SC samples was similar except for HPV 66 which showed a trend to clear slower by SC (p = 0.09). When comparing methods in the same woman, time-to-clearance was similar for all types except for HPV 16 which showed a trend to clear slower by CC-L means (p = 0.08). When we examined pattern of clearance among the CC-L samples, the fastest types to clear were HPV 6, 18, 66, 84 and 39 and the slowest were HPV 62, 68, 59 and 16. These patterns of fast and slow were similar for SC samples. Our findings suggest using SC vaginal swabs would observe similar natural histories of HPV compared to studies using CC-L specimens making self-testing feasible for repeated HPV DNA detection.

Prospective randomized study for hydrotubation versus no hydrotubation before intrauterine insemination in unexplained infertility.

The purpose of the study was to investigate the value of hydrotubation before intrauterine insemination (IUI). In 228 patients with the diagnosis of unexplained infertility, ovarian stimulation was performed before IUI, using 100mg of clomiphine citrate for 5 days from day 3 of the cycle and one ampoule of human menopausal gonadotrophin for 5 days from day 6 of the cycle. Folliculometry and determination of LH concentration in urine were performed daily until LH became positive, then randomization for hydrotubation before IUI versus no hydrotubation was performed. Fifteen patients were cancelled from the study due to poor response or stimulation of three or more follicles. A total of 213 patients were randomized as follows: 103 patients undergoing hydrotubation using 50 ml of saline and 110 patients with no hydrotubation. IUI was performed the following day and ongoing pregnancy occurred in 13 patients (12.6%) in the hydrotubation group and nine patients (8.2%) in the non-hydrotubation group with no significant difference (OR 1.66; 95% CI 0.62-4.63). In conclusion, hydrotubation before IUI does not improve pregnancy rate.

miRNA profiling of primate cervicovaginal lavage and extracellular vesicles reveals miR-186-5p as a potential antiretroviral factor in macrophages.

Cervicovaginal secretions, or their components collected, are referred to as cervicovaginal lavage (CVL). CVL constituents have utility as biomarkers and play protective roles in wound healing and against HIV-1 infection. However, several components of cervicovaginal fluids are less well understood, such as extracellular RNAs and their carriers, for example, extracellular vesicles (EVs). EVs comprise a wide array of double-leaflet membrane extracellular particles and range in diameter from 30 nm to over one micron. The aim of this study was to determine whether differentially regulated CVL microRNAs (miRNAs) might influence retrovirus replication. To this end, we characterized EVs and miRNAs of primate CVL during the menstrual cycle and simian immunodeficiency virus (SIV) infection of macaques. EVs were enriched by stepped ultracentrifugation, and miRNA profiles were assessed with a medium-throughput stem-loop/hydrolysis probe qPCR platform. Whereas hormone cycling was abnormal in infected subjects, EV concentration correlated with progesterone concentration in uninfected subjects. miRNAs were present predominantly in the EV-depleted CVL supernatant. Only a small number of CVL miRNAs changed during the menstrual cycle or SIV infection, for example, miR-186-5p, which was depleted in retroviral infection. This miRNA inhibited HIV replication in infected macrophages in vitro. In silico target prediction and pathway enrichment analyses shed light on the probable functions of miR-186-5p in hindering HIV infections via immunoregulation, T-cell regulation, disruption of viral pathways, etc. These results provide further evidence for the potential of EVs and small RNAs as biomarkers or effectors of disease processes in the reproductive tract.

Association between vaginal washing and vaginal bacterial concentrations.

Vaginal washing is a common practice associated with adverse outcomes including bacterial vaginosis (BV) and HIV infection. Prior studies have not examined the associations between vaginal washing and individual vaginal bacteria, or whether these associations are independent of the effect of vaginal washing on BV. The purpose of this study was to characterize the association between vaginal washing and the presence and concentrations of vaginal bacteria associated with optimal and sub-optimal vaginal states. The analysis utilized data from participants in the placebo arm of the Preventing Vaginal Infections trial, which enrolled HIV-uninfected women from the United States and Kenya. Detection of bacterial taxa associated with BV was compared between visits with versus without reported vaginal washing. The effect of vaginal washing on a number of vaginal bacteria differed substantially (p<0.05) between the US and Kenya, so results were stratified by country. In US women, vaginal washing was associated with a significantly higher likelihood of detection of BV associated bacterium 1 (BVAB1) (relative risk [RR] 1.55, 95% confidence interval [CI] 1.15-2.09, p = 0.004), BVAB2 (RR 1.99, 95%CI 1.46-2.71, p<0.001), Mageeibacillus indolicus (RR 2.08, 95%CI 1.46-2.96, p<0.001), Atopobium vaginae (RR 1.34, 95%CI 1.13-1.59, p = 0.001), Leptotrichia/Sneathia species (RR 1.66, 95% CI 1.33-2.09, p<0.001), Megasphaera species (RR 1.78, 95%CI 1.34-2.37, p<0.001) and Gardnerella vaginalis (RR 1.08, 95%CI 1.01-1.16, p = 0.02). No significant association between vaginal washing and bacterial detection was found in Kenyan women. Adjustment for bacterial vaginosis diagnosed by Gram stain did not alter these results. This study provides evidence that the association between vaginal washing and detection of individual bacterial taxa can vary regionally. For some vaginal bacteria, the association with vaginal washing may be independent of the effect on Gram stain detection of BV. Larger prospective studies in diverse geographic settings should explore whether eliminating vaginal washing impacts the presence and concentrations of key vaginal bacteria.

Vaginal herb use and Chlamydia trachomatis infection: cross-sectional study among women of various ethnic groups in Suriname.

OBJECTIVE: Vaginal steam baths with herb leaves (herb use) is practised by some Surinamese women. We assessed herb use among women from the five most prevalent ethnic groups, and if herb use is associated with Chlamydia trachomatis infection. SETTING: Participants were recruited at a sexually transmitted infection (STI) clinic and a family planning clinic (FP) in Paramaribo, Suriname. PARTICIPANTS: 1040 women were included subsequently, comprising the following ethnic groups: Creole (26.7%), Hindustani (24.6%), Javanese (15.7%), Maroon (13.3%) and mixed descent (19.7%). METHODS: Nurses collected a questionnaire and vaginal swabs for nucleic acid amplification C. trachomatis testing. PRIMARY OUTCOMES: Determinants of vaginal herb use and C. trachomatis infection via univariable and multivariable logistic regression. RESULTS: Herb use was most common among Maroon (68.8%) and Creole women (25.2%). In multivariable analysis including only Maroon and Creole women, determinants significantly associated with vaginal herb use were (OR; 95% CI): Maroon ethnic descent (5.33; 3.26 to 8.71 vs Creole), recruitment at the STI clinic (2.04; 1.24 to 3.36 vs FP), lower education levels (3.80; 1.68 to 8.57 lower vs higher, and 2.02; 0.90 to 4.51 middle vs higher). Lower age and recruitment at the STI clinic were associated with C. trachomatis infection, but not vaginal herb use. CONCLUSION: In Suriname, vaginal herb use is common among Maroon and Creole women. Education, ethnic group and recruitment site were determinants for herb use. Vaginal herb use was not a determinant of C. trachomatis infection. Future research should focus on the effect of herb use on the vaginal microbiome and mucosal barrier.

One-year follow-up of single-visit approach to cervical cancer prevention based on visual inspection with acetic acid wash and immediate cryotherapy in rural Thailand.

The aim is to evaluate 1) the visibility of cervical squamocolumnar junction (SCJ) after cryotherapy treatment and 2) to evaluate the effectiveness of cryotherapy treatment originally performed as part of a safety, acceptability, and feasibility (SAFE) demonstration project evaluating the SAFE of visual inspection with acetic acid (VIA) followed by immediate offer of cryotherapy among those who were tested positive and eligible for treatment. A total of 704 women presented at 1-year follow-up exam during which VIA was performed again by nurses. Six hundred and forty eight (92.0%) women received colposcopy and any kind of biopsy, if indicated, by trained physician colposcopists at a referral hospital. At 1 year, VIA nurses assessed 42 of 648 referred women (6.5%) as abnormal (test positive or suspected cancer). The SCJ was visible to the colposcopists in 91.7% (594/648) of the women. Among 42 women assessed as abnormal by the nurses, colposcopic findings were abnormal in 83.3% (35/42), with one low-grade squamous intraepithelial lesion, two high-grade squamous intraepithelial lesion (HSIL), and one adenocarcinoma confirmed later by biopsy. Among 606 VIA negative women, colposcopy was abnormal in only 23.4% (142/606), with two cases of HSIL confirmed later. Given that the SCJ was visible in the vast majority of women (91.7%) after cryotherapy, VIA could be used to provide follow-up for women previously treated. The disease negative rate after cryotherapy (no human papillomavirus infection, no cervical intraepithelial neoplasia, and no cancer) at 1 year after treatment was 85.5% (554/648).

Effect on fertility of human chorionic gonadotrophin and uterine lavage with oxytocin performed after mating in Arabian barren mares.

The objective of the present study was to evaluate the beneficial effect of hCG injected immediately after mating in Arabian barren mares treated with uterine lavage and oxytocin. Arabian barren mares (n=36) with PMIE were subjected to detailed clinical examinations including palpation per rectum, vaginoscopy, and cytological examination. After mating the 36 mares were randomly divided into four groups. The mares in group 1 (n=10) were immediately after breeding injected with hCG 3,000 IU IM. Uterine lavage with 1L of N-saline containing 4 million IU of crystalline penicillin and 4 g of streptomycin sulphate was performed 4h after breeding. Then mares received two injections of oxytocin 40 IU IM 2h apart after 6h of mating. Mares in group 2 (n=10) treated with uterine lavage and oxytocin as group 1. While mares in group 3 (n=10) received uterine lavage only. A control group (n=6) as group 4 did not received any treatment. The results of clinical examination indicated that 69.4% of PMIE mares were harboring severe endometritis and 30.6% with a moderate form of endometritis. Significant (P<0.01) increase in lymphocytes were founded in barren mares included in this study. Higher pregnancy rate (P<0.01) was founded in Arabian barren mares 80% injected with hCG immediately after breeding and uterine lavage and oxytocin. No significant difference was found in mares received uterine lavage and oxytocin and uterine lavage only. In a conclusion, administration of hCG immediately after mating and intrauterine lavage containing antibiotics performed 4h and two injections of oxytocin 40 IU IM 2h apart after 6h of mating had improved fertility of Arabian barren mares.

[Hydrating cleansing: efficacy and tolerability of new formulations with hyaluronic acid 0.2% for intimate hygiene in the woman in fertile age and menopause].

Dehydration of genital areas, known as vaginal dryness, frequently affects woman's life, from fertile to postmenopausal period, and must be treated with specific products, including proper intimate cleansing. Based on that, two new cleanser formulations, characterized by Hyaluronic Acid 0.2% as main ingredient, have been developed (Hyalo Gyn® Intimo Active and Hyalo Gyn® Intimo Advance), with the aim to provide an effective hydration of the vaginal, vulvar, perianal and anal areas beyond guaranteeing daily intimate hygiene. The two intimate cleansing mousses have been formulated in mousse and differentiated, in terms of ingredients, accordingly to the different physiological conditions and female needs of fertile age and menopause respectively. Clinical trials conducted on women of childbearing age and menopause showed that daily cleansing with these intimate washes promotes hydration of vaginal tissues thanks to the presence of hyaluronic acid. In particular, the cleansing mousse for fertile women gives also a soothing effect, offers antimicrobial protection and a long lasting feeling of freshness. The cleansing mousse for menopausal women provides a freshness sensation, improves elasticity and tonicity and exerts an anti-smell and anti-oxidative effect.

Immune biomarkers and anti-HIV activity in the reproductive tract of sexually active and sexually inactive adolescent girls.

PROBLEM: Adolescent girls are disproportionately affected by the HIV/AIDS pandemic, accounting for 22% of all new HIV infections globally. Yet little is known regarding the immune microenvironment of the adolescent female reproductive tract, especially regarding differences among sexually active and inactive girls, a critical parameter to evaluate HIV susceptibility associated with young age and sexual debut. METHODS: Cervico-vaginal lavage (CVL) was collected from sexually active (10) and inactive (8) girls aged 11-19 years and analyzed by ELISA for inflammation-associated biomarkers IL-6, IL-8, TNF-α, MIP-3α, IL-1α, IL-1ß, matrix metalloproteinases (MMP) 1, 2, 7, 8, and 9, as well as anti-HIV mediators, Elafin, SLPI, human beta-defensin 2, and tissue inhibitor of matrix metalloproteinases (TIMP) 1 and 2. Cervical ectopy was analyzed using Volocity. Anti-HIV activity was determined by TZM-bl assay. Statistical analyses were performed using GraphPad Prism and R. RESULTS: Sexually inactive girls had significantly higher levels of TNF-α (P = .029) in CVL compared to sexually active girls. In contrast, sexually active girls showed a trend toward higher levels of IL-1α (P = .051) compared to the sexually inactive girls. Heat-map correlations between cervical ectopy and immune biomarkers were also distinct between the 2 populations with significant positive associations between % ectopy and inflammation-associated biomarkers IL-6, IL-1ß, IL-8, MIP-3α, MMP-8, and MMP-9 observed in the sexually inactive but not sexually active group. CONCLUSION: Higher pro-inflammatory biomarker TNF-α, as well as a distinct inflammation-associated immune clustering in sexually inactive girls, can potentially increase risk for infections including HIV upon sexual debut. Future studies with larger sample sizes are needed to characterize the immune parameters associated with sexual activity.

Lower genital tract cytokine profiles in South African women living with HIV: influence of mucosal sampling.

Measurement of cytokines in the lower female genital tract offer insight into risk for HIV infection and reproductive complications. However, few studies have systematically compared mucosal collection methods or whether collection order matters. We compared longitudinal cytokine profiles in matched genital samples collected from women living with HIV using menstrual cup (MC), endocervical swabs (ECS) and swab-enriched cervicovaginal lavage (eCVL). Samples were collected at enrollment [MC:ECS:eCVL], 3-months (ECS:eCVL:MC) and 6-months (eCVL:MC:ECS) and concentrations of 28 cytokines determined by Luminex. Cytokine clustering was assessed using Principle Component Analysis (PCA), Partial Least Squares Discriminant Analysis (PLSDA) and factor analysis. Generally, higher cytokine concentrations were detected in MC samples, followed by ECS and eCVL, irrespective of study visit or sampling order. Factor analysis and PCA identified ECS to be inferior for measuring regulatory cytokines and IP-10 than eCVL or MC. Although concentrations differed, the majority of cytokines correlated between methods. Sampling order influenced cytokine concentrations marginally, and cytokines clustered more strongly by method than study visit. Variance in profiles was lowest in MC, suggesting greater consistency of sampling compared to other methods. We conclude that MC sampling offered advantages over other methods for detecting cytokines in women, with order marginally influencing profiles.
