    Bacterial vaginosis, trichomoniasis, and vulvovaginal candidiasis are the most common infectious causes of vaginitis. Bacterial vaginosis occurs when the normal lactobacilli of the vagina are replaced by mostly anaerobic bacteria. Diagnosis is commonly made using the Amsel criteria, which include vaginal pH greater than 4.5, positive whiff test, milky discharge, and the presence of clue cells on microscopic examination of vaginal fluid. Oral and topical clindamycin and metronidazole are equally effective at eradicating bacterial vaginosis. Symptoms and signs of trichomoniasis are not specific; diagnosis by microscopy is more reliable. Features of trichomoniasis are trichomonads seen microscopically in saline, more leukocytes than epithelial cells, positive whiff test, and vaginal pH greater than 5.4. Any nitroimidazole drug (e.g., metronidazole) given orally as a single dose or over a longer period resolves 90 percent of trichomoniasis cases. Sex partners should be treated simultaneously. Most patients with vulvovaginal candidiasis are diagnosed by the presence of vulvar inflammation plus vaginal discharge or with microscopic examination of vaginal secretions in 10 percent potassium hydroxide solution. Vaginal pH is usually normal (4.0 to 4.5). Vulvovaginal candidiasis should be treated with one of many topical or oral antifungals, which appear to be equally effective. Rapid point-of-care tests are available to aid in accurate diagnosis of infectious vaginitis. Atrophic vaginitis, a form of vaginitis caused by estrogen deficiency, produces symptoms of vaginal dryness, itching, irritation, discharge, and dyspareunia. Both systemic and topical estrogen treatments are effective. Allergic and irritant contact forms of vaginitis can also occur. PMID:21524046

    SciTech Connect

    Lesavoy, M.A.

    1985-05-01

    Vaginal reconstruction can be an uncomplicated and straightforward procedure when attention to detail is maintained. The Abbe-McIndoe procedure of lining the neovaginal canal with split-thickness skin grafts has become standard. The use of the inflatable Heyer-Schulte vaginal stent provides comfort to the patient and ease to the surgeon in maintaining approximation of the skin graft. For large vaginal and perineal defects, myocutaneous flaps such as the gracilis island have been extremely useful for correction of radiation-damaged tissue of the perineum or for the reconstruction of large ablative defects. Minimal morbidity and scarring ensue because the donor site can be closed primarily. With all vaginal reconstruction, a compliant patient is a necessity. The patient must wear a vaginal obturator for a minimum of 3 to 6 months postoperatively and is encouraged to use intercourse as an excellent obturator. In general, vaginal reconstruction can be an extremely gratifying procedure for both the functional and emotional well-being of patients.

    PubMed

    Reichman, Orna; Sobel, Jack

    2014-10-01

    Desquamative inflammatory vaginitis (DIV) is an uncommon form of chronic purulent vaginitis. It occurs mainly in Caucasians with a peak occurrence in the perimenopause. Symptoms and signs are nonspecific; DIV is a diagnosis of exclusion, and other causes of purulent vaginitis should be excluded. The main symptoms include purulent discharge, vestibulo-vaginal irritation, and dyspareunia. Examination of vaginal walls shows signs of inflammation with increased erythema and petechiae. Through microscopy (wet mount) of the vaginal secretions, DIV is defined by an increase in inflammatory cells and parabasal epithelial cells (immature squamous cells). Vaginal flora is abnormal and pH is always elevated above 4.5. Although etiology and pathogenesis remain unknown, the favorable response to anti-inflammatory agents suggests that the etiology is immune mediated. Either local vaginal clindamycin or vaginal corticosteroids are adequate treatment. As a chronic condition, maintenance treatment should be considered as relapse is common. PMID:25132275

  2. Management of aerobic vaginitis.

    PubMed

    Tempera, Gianna; Furneri, Pio Maria

    2010-01-01

    Aerobic vaginitis is a new nonclassifiable pathology that is neither specific vaginitis nor bacterial vaginosis. The diversity of this microbiological peculiarity could also explain several therapeutic failures when patients were treated for infections identified as bacterial vaginosis. The diagnosis 'aerobic vaginitis' is essentially based on microscopic examinations using a phase-contrast microscope (at 400 magnification). The therapeutic choice for 'aerobic vaginitis' should take into consideration an antibiotic characterized by an intrinsic activity against the majority of bacteria of fecal origin, bactericidal effect and poor/absent interference with the vaginal microbiota. Regarding the therapy for aerobic vaginitis when antimicrobial agents are prescribed, not only the antimicrobial spectrum but also the presumed ecological disturbance on the anaerobic and aerobic vaginal and rectal microbiota should be taken into a consideration. Because of their very low impact on the vaginal microbiota, kanamycin or quinolones are to be considered a good choice for therapy. PMID:21051843

  3. Vaginitis: diagnosis and management.

    PubMed

    Quan, Martin

    2010-11-01

    Vaginitis is one of the most common ambulatory problems to occur in women. It is a disorder responsible for > 10% of visits made to providers of women's health care. Although vaginal infections are the most common cause, other considerations include cervicitis, a normal vaginal discharge, foreign-body vaginitis, contact vaginitis, atrophic vaginitis, and desquamative inflammatory vaginitis. The medical history and examination are an important source of clues to the underlying diagnosis. However, making a definitive diagnosis requires skillful performance of office laboratory procedures, including the vaginal pool wet mount examination, determination of the vaginal pH, and the whiff test. Vaginal and cervical cultures, nucleic acid tests, and point-of-care tests are available and may be required in selected patients. Once a specific diagnosis is made, effective therapy can be prescribed. Candida vaginitis is generally treated with either the vaginal administration of an imidazole or triazole antifungal agent or the prescription of oral fluconazole. Oral nitroimidazole agents, metronidazole or tinidazole, are the only effective treatments for trichomoniasis in the United States. Bacterial vaginosis, which has been linked to important gynecologic and pregnancy complications, can be treated with an available oral or topical agent containing either a nitroimidazole or clindamycin.

    2004-12-01

    Common infectious forms of vaginitis include bacterial vaginosis, vulvovaginal candidiasis, and trichomoniasis. Vaginitis also can occur because of atrophic changes. Bacterial vaginosis is caused by proliferation of Gardnerella vaginalis, Mycoplasma hominis, and anaerobes. The diagnosis is based primarily on the Amsel criteria (milky discharge, pH greater than 4.5, positive whiff test, clue cells in a wet-mount preparation). The standard treatment is oral metronidazole in a dosage of 500 mg twice daily for seven days. Vulvovaginal candidiasis can be difficult to diagnose because characteristic signs and symptoms (thick, white discharge, dysuria, vulvovaginal pruritus and swelling) are not specific for the infection. Diagnosis should rely on microscopic examination of a sample from the lateral vaginal wall (10 to 20 percent potassium hydroxide preparation). Cultures are helpful in women with recurrent or complicated vulvovaginal candidiasis, because species other than Candida albicans (e.g., Candida glabrata, Candida tropicalis) may be present. Topical azole and oral fluconazole are equally efficacious in the management of uncomplicated vulvovaginal candidiasis, but a more extensive regimen may be required for complicated infections. Trichomoniasis may cause a foul-smelling, frothy discharge and, in most affected women, vaginal inflammatory changes. Culture and DNA probe testing are useful in diagnosing the infection; examinations of wet-mount preparations have a high false-negative rate. The standard treatment for trichomoniasis is a single 2-g oral dose of metronidazole. Atrophic vaginitis results from estrogen deficiency. Treatment with topical estrogen is effective. PMID:15606061

    2011-01-01

    Management of vaginal prolapse in the elderly lacks a uniform consensus and continues to remain challenging. The authors report a case of an elderly lady who presented with a spontaneous vaginal evisceration. She had a long-standing vaginal prolapse being controlled by a shelf pessary, which, in her case became displaced 2 weeks prior to admission. The patient underwent a laparotomy with an intent to replace the bowel back within the peritoneal cavity and repair the vault. During the pelvic floor repair, she sustained an inadvertent button-hole injury to the rectum, which was oversewn. She went on to develop a rectovaginal fistula requiring a de-functioning colostomy. The patient made good recovery subsequently. PMID:22707628

  13. Staging for vaginal cancer.

    Rajaram, Shalini; Maheshwari, Amita; Srivastava, Astha

    2015-08-01

    Vaginal cancer is a rare cancer comprising about 3% of all gynecologic cancers. Primary vaginal cancer should be carefully assigned as spread from cervix, vulva, and other metastatic tumors to vagina can occur. Although vaginal cancer traditionally occurs in older postmenopausal women, the incidence of high-risk human papillomavirus (HPV)-induced cancers is increasing in younger women. Squamous cell carcinoma is still the most common histopathologic type followed by adenocarcinoma. With decreasing use of diethylstilbestrol in pregnancy, non-diethylstilbestrol-associated cancers are described. The Federation Internationale de Gynecologie et d'Obstetrique (FIGO) staging of vaginal cancer (2009) follows the same rules as cervical cancer; it is clinically staged and allows the use of routine investigative modalities for staging. Although FIGO encourages the use of advanced imaging modalities, such as computed tomography, magnetic resonance imaging (MRI), and positron emission tomography (PET), to guide therapy, the imaging findings may not be used to change or reassign the stage. TNM staging is the pathologic staging system proposed by the American Joint Committee on Cancer, and information available from examination of the resected specimen, including pelvic and inguinal lymph nodes, may be used for staging.

    Objective To compare maternal and neonatal outcomes in women undergoing a second stage cesarean after a trial of operative vaginal delivery with women undergoing a second stage cesarean without such an attempt. Methods This study is a secondary analysis of the women who underwent second stage cesarean. .The maternal outcomes examined included blood transfusion, endometritis, wound complication, anesthesia use, and maternal death. Infant outcomes examined included umbilical artery pH < 7.0, Apgar of 3 or less at 5 minutes, seizures within 24 hours of birth, hypoxic ischemic encephalopathy (HIE), stillbirth, skull fracture, and neonatal death. Results Of 3189 women who underwent second stage cesarean, operative vaginal delivery was attempted in 640. Labor characteristics were similar in the two groups with the exception of the admission to delivery time and cesarean indication. Those with an attempted operative vaginal delivery were more likely to undergo cesarean delivery for a non-reassuring fetal heart rate tracing (18.0% vs 13.9%, p=.01), have a wound complication (2.7% vs 1.0%; OR 2.65 95% CI 1.434.91), and require general anesthesia (8.0% vs 4.1%, OR 2.05 95% CI 1.442.91). Neonatal outcomes including umbilical artery pH less than 7.0, Apgar at or below 3 at 5 minutes, and hypoxic ischemic encephalopathy were more common for those with an attempted operative vaginal delivery. This was not significant when cases with a non-reassuring fetal heart rate tracing were removed. Conclusion Cesarean delivery after an attempt at operative vaginal delivery was not associated with adverse neonatal outcomes in the absence of a non-reassuring fetal heart rate tracing.

    2014-01-01

    Background Episiotomy is done to prevent severe perineal tears, but its routine use has been questioned. The relative effects of midline compared with midlateral episiotomy are unclear. Objectives The objective of this review was to assess the effects of restrictive use of episiotomy compared with routine episiotomy during vaginal birth. Search methods We searched the Cochrane Pregnancy and Childbirth Groups Trials Register (March 2008). Selection criteria Randomized trials comparing restrictive use of episiotomy with routine use of episiotomy; restrictive use of mediolateral episiotomy versus routine mediolateral episiotomy; restrictive use of midline episiotomy versus routine midline episiotomy; and use of midline episiotomy versus mediolateral episiotomy. Data collection and analysis The two review authors independently assessed trial quality and extracted the data. Main results We included eight studies (5541 women). In the routine episiotomy group, 75.15% (2035/2708) of women had episiotomies, while the rate in the restrictive episiotomy group was 28.40% (776/2733). Compared with routine use, restrictive episiotomy resulted in less severe perineal trauma (relative risk (RR) 0.67, 95% confidence interval (CI) 0.49 to 0.91), less suturing (RR 0.71, 95% CI 0.61 to 0.81) and fewer healing complications (RR 0.69, 95% CI 0.56 to 0.85). Restrictive episiotomy was associated with more anterior perineal trauma (RR 1.84, 95% CI 1.61 to 2.10). There was no difference in severe vaginal/perineal trauma (RR 0.92, 95% CI 0.72 to 1.18); dyspareunia (RR 1.02, 95% CI 0.90 to 1.16); urinary incontinence (RR 0.98, 95% CI 0.79 to 1.20) or several pain measures. Results for restrictive versus routine mediolateral versus midline episiotomy were similar to the overall comparison. Authors conclusions Restrictive episiotomy policies appear to have a number of benefits compared to policies based on routine episiotomy. There is less posterior perineal trauma, less suturing and fewer complications, no difference for most pain measures and severe vaginal or perineal trauma, but there was an increased risk of anterior perineal trauma with restrictive episiotomy.

    Serum antibody titers to Candida albicans were estimated in 37 women with recurrent vaginal candidiasis and in 148 normal American and Finnish subjects, using the passive-hemagglutination technique. The antibody titers ranged from 0 to 16 in normal individuals and 4 to 256 in vaginal candidiasis patients. Antibodies to C. albicans in the sera of vaginal candidiasis patients were found to be the secretory immunoglobulin A type, as determined by gel filtration and double-diffusion tests. The results were confirmed by the indir-ct fluorescent-antibody technique. Our findings suggest that, in vaginal candidiasis, the antibody response is mainly local, consisting of secretory immunoglobulin A, some of which finds its way into systemic circulation.

    1978-03-01

    With use of a discriminative control procedure and operant techniques, women significantly increased their vaginal pulse amplitude (produced vaginal vasodilation) but did not significantly decrease vaginal pulse amplitude (produce vaginal vasoconstriction). Acquisition of vaginal pulse amplitude control was rapid with no significant improvement over trials or the 5 experimental days. Specificity of vaginal pulse amplitude control occurred in relation to the other vasomotor responses, including vaginal blood volume and digital pulse amplitude. Vagnial pulse amplitude changes were not related to somatic-muscular, respiratory, or heart-rate changes. Women who used oral contraceptives were better able to control vaginal pulse amplitude than women who used other forms of birth control. Although the sexual behavior of these two groups and did not differ, women in the latter group tended to be more clitorally oriented. PMID:667189

    Vaginal infections, affecting half of all women, are more severe in women with AIDS. The infection vulva vaginitis, caused by candida, may require medical attention. The doctor performs a pelvic exam and examines vaginal fluids under a microscope. Antibiotics, diet, or a suppressed immune system can increase candida yeast presence. Sweets should be avoided, as well as foods high in leavening, such as bread, cheese, fruit, or alcoholic beverages. Vegetables, grains, rice and wheat can be added to the diet. Eating a half-cup of yogurt daily will help maintain a proper level of yeast. Acidophilus capsules can be taken two or three times daily to relieve digestive problems. Raw or cooked garlic can be used as a vaginal suppository at night. Pau D'arco, the bark of a South American tree, is also anti-yeast. Boil for ten to twenty minutes, and take a teaspoon two or three times a day. Tea, or vinegar and water, can be used as a douche. Some women get relief by adding a half-cup of white vinegar to their bath. Do not wash genitals with soap and do not use sanitary napkins or tampons. Visit a doctor if the condition persists.

    Vaginal cancer is rare worldwide and represents 2% of all gynaecological cancers in Singapore. Primary vaginal malignancies are rare and vaginal metastases constitute the majority of vaginal malignancies. Most of these metastases arise from the cervix, endometrium or ovary, although they can also metastasise from distant sites such as the colon, breast and pancreas. We report a rare case of vaginal metastasis in a patient with previous gastric and rectal adenocarcinomas. An 89-year-old woman with a history of gastric and rectal malignancy presented with postmenopausal bleeding. A 2-cm vaginal tumour at the introitus was discovered upon examination. This case demonstrates the importance of performing a gynaecological examination during follow-up for patients with a history of malignancy. The prognosis for vaginal metastasis is poor, as it is often associated with disseminated disease. Depending on the extent of the lesions, radiotherapy or surgery can be considered. PMID:26311914

    Different brands of vaginal tampons varied significantly (p less than 0.0001) in their anti-bacterial effects when tested with 46 strains of Neisseria gonorrhoeae. Gonococcal strains recovered from patients with disseminated infections were substantially more sensitive to the anti-bacterial effects of tampons than were strains from patients with uncomplicated genital infections. Strains from patients with pelvic inflammatory disease were moderately sensitive. Tampons showing strong in-vitro antigonococcal effects were also generally effective in vivo in eliminating gonococcal infections from subcutaneous chambers in mice. Extracts of the Rely tampon showed no in-vitro antigonococcal effect, however, but did induce antibacterial activity when injected into subcutaneous chambers in mice. These results emphasise the importance of both in-vitro as well as in-vivo testing of tampon materials to elucidate more fully the nature of their antibacterial effects and their potential for affecting vaginal pathogens and disease processes.

    Sixteen patients with cancer of the vagina that were controlled locally for a minimum of eighteen months after teletherpay (T) or brachytherapy (B) or both (T and B), were analyzed for radiation tolerance of the vaginal mucosa. The site of vaginal necrosis did not always coincide with the site of the tumor. The posterior wall appeared more vulnerable than the anterior or lateral walls. For the distal vaginal mucosa, necrosis requiring surgical intervention occurred following combined T and B, if summated rad exceeded9800. The upper vagina tolerated higher dosages. No patient surgery for upper vaginal necrosis even though summated (T and B) dosage up to 14,000 rad was applied. Placing radioactive needles on the surface of the vaginal cylinder with or without interstitial perincal needles should be avoided. Further accumulation of data is needed to define these vaginal mucosa tolerance limits more closely.

    Introduction Isolated vaginal metastases from colorectal cancer are extremely rare. There are only a few reported cases in the English literature, and the characteristics of such cases of metastasis remain relatively unknown. Presentation of case We present a case of isolated vaginal metastasis from rectal cancer in a 78-year-old female patient. The patient had no symptoms related to vaginal tumor. Magnetic resonance imaging (MRI) showed thickening of the middle rectum and a vaginal tumor. Biopsy from the vaginal tumor showed adenocarcinoma, similar to the rectal lesion. Low anterior resection with ileostomy, hystero-oophorectomy, and transvaginal tumor resection was performed. After nineteen months, computed tomography scan revealed multiple lung metastases and recurrent tumor in the pelvis. The patient refused chemotherapy and is alive three months after developing recurrent disease. Discussion Most cases of primary vaginal carcinoma are squamous cell carcinoma. Other histologic types such as adenocarcinoma are usually metastatic lesions. Primary lesions associated with metastatic vaginal adenocarcinoma are most often the uterus, and are very rarely from the colon or rectum. We review previous case reports of isolated vaginal metastases from colorectal cancer and discuss their symptoms, treatments, and outcomes. Conclusion We should keep the vagina within the field of view of pelvic MRI, which is one of the preoperative diagnostic tools for colorectal cancer. If female patients show gynecological symptoms, gynecological examination should be recommended. Isolated vaginal metastases are an indication for surgical resection, and adjuvant chemotherapy is also recommended. PMID:26793313

    Deep sequence analysis of the vaginal microbiome is revealing an unexpected complexity that was not anticipated as recently as several years ago. The lack of clarity in the definition of a healthy vaginal microbiome, much less an unhealthy vaginal microbiome, underscores the need for more investigation of these phenomena. Some clarity may be gained by the careful analysis of the genomes of the specific bacteria in these women. Ongoing studies will clarify this process and offer relief for women with recurring vaginal maladies and hope for pregnant women to avoid the experience of preterm birth. PMID:25439274

This does not reduce the number of volunteers exposed to possible risk, but it shifts the allotment of risk from those conducting the trial to those women who may be least able to make autonomous decisions. Alternative ways of meeting the obligation to offer volunteers active benefits are explored. Counseling the use of condoms prolongs clinical trials and could cause tens of thousands of otherwise avoidable deaths. PMID:10667178

    2014-01-01

    The concern that vaginal birth will result in loose vagina and negatively affect their postnatal sexual life is one of the main reasons that many women choose cesarean section. Here we aimed to implement a new device to measure and compare the intra-vaginal pressures between women who gave vaginal birth and those who had cesarean section, and to evaluate the relationship between sexual function and type of delivery by Female Sexual Function Index (FSFI). A total of 165 women including 88 in the vaginal-delivery group and 77 in the cesarean-delivery group were recruited in the study. Significant differences in intra-vaginal pressures were found between the two groups, and intra-vaginal pressures of vaginal-delivery group were lower than those of cesarean-delivery group. Significant difference was also found in coitus time. However, no significant difference was found regarding sexual satisfaction and sexual function indicated by the FSFI. We concluded that vaginal delivery indeed may result in loose vagina compared with cesarean delivery. However, it did not negatively affect the postnatal sexual function. Therefore, women should be assured that their sexual functions won't be affected by the types of delivery. PMID:23676889

An expansion of mixed aerobic microflora, especially Group B Streptococcus--GBS, Escherichia coli--E. coli, Enterococcus spp., and the development of inflammation of the vaginal mucous membrane due to a decreasing amount of Lactobacillus spp., have been observed in women with AV. Disruptions of the vaginal ecosystem during AV cause an increase in pH to >6, a decrease in lactates concentration and an increase in proinflammatory cytokines concentration in vaginal discharge. An optimal treatment scheme for AV, which includes antibacterial agents and simultaneously normalizes the vaginal ecosystem, has not been established until today. PMID:17899708

  14. Effect of vaginal or systemic estrogen on dynamics of collagen assembly in the rat vaginal wall.

    2015-02-01

    The objective of this study was to compare the effects of systemic and local estrogen treatment on collagen assembly and biomechanical properties of the vaginal wall. Ovariectomized nulliparous rats were treated with estradiol or conjugated equine estrogens (CEEs) either systemically, vaginal CEE, or vaginal placebo cream for 4 wk. Low-dose local CEE treatment resulted in increased vaginal epithelial thickness and significant vaginal growth without uterine hyperplasia. Furthermore, vaginal wall distensibility increased without compromise of maximal force at failure. Systemic estradiol resulted in modest increases in collagen type I with no change in collagen type III mRNA. Low-dose vaginal treatment, however, resulted in dramatic increases in both collagen subtypes whereas moderate and high dose local therapies were less effective. Consistent with the mRNA results, low-dose vaginal estrogen resulted in increased total and cross-linked collagen content. The inverse relationship between vaginal dose and collagen expression may be explained in part by progressive downregulation of estrogen receptor-alpha mRNA with increasing estrogen dose. We conclude that, in this menopausal rat model, local estrogen treatment increased total and cross-linked collagen content and markedly stimulated collagen mRNA expression in an inverse dose-effect relationship. High-dose vaginal estrogen resulted in downregulation of estrogen receptor-alpha and loss of estrogen-induced increases in vaginal collagen. These results may have important clinical implications regarding the use of local vaginal estrogen therapy and its role as an adjunctive treatment in women with loss of vaginal support.

    Background: Atrophic vaginitis is a disease, which affects up to 50% of postmenopausal women. This study compared the effectiveness and user-friendliness of Vagifem (an estradiol vaginal tablet) and vaginal estrogen cream in the treatment of atrophic vaginitis. Materials and Methods: One hundred and sixty postmenopausal women with symptoms of atrophic vaginitis were randomly divided into two groups of treatment with Vagifem or with vaginal estrogen cream for 12 weeks. Patients used the medication daily for the first 2 weeks of the study, and twice weekly. Severity of vaginal atrophy and four main symptoms of atrophic vaginitis including dysuria, dyspareunia, vaginal itching, and dryness were evaluated and compared before and after treatment. In addition, patients were asked regarding user-friendliness and hygienic issues of medications. Results: Both vaginal estrogen cream and Vagifem significantly improved symptoms of atrophic vaginitis but in terms of effectiveness for the treatment symptoms of atrophic vaginitis, there was no significant difference between the two medications. Vagifem compared to estrogen cream resulted in significantly lower rate of hygienic problems (0% versus 23%, P < 0.001), and was reported by the patients as a significantly easier method of treatment (90% versus 55%, P < 0.0001). Conclusion: This investigation showed that Vagifem is an appropriate medication for the treatment of atrophic vaginitis, which is as effective as vaginal estrogen creams and is more user-friendly.

  1. Management of Spontaneous Vaginal Delivery.

    PubMed

    Dresang, Lee T; Yonke, Nicole

    2015-08-01

    Most of the nearly 4 million births in the United States annually are normal spontaneous vaginal deliveries. In the first stage of labor, normal birth outcomes can be improved by encouraging the patient to walk and stay in upright positions, waiting until at least 6 cm dilation to diagnose active stage arrest, providing continuous labor support, using intermittent auscultation in low-risk deliveries, and following the Centers for Disease Control and Prevention guidelines for group B streptococcus prophylaxis. Most women with a low transverse uterine incision are candidates for a trial of labor after cesarean delivery and should be counseled accordingly. Pain management during labor includes complementary modalities and systemic opioids, epidural anesthesia, and pudendal block. Outcomes in the second stage of labor can be improved by using warm perineal compresses, allowing women more time to push before intervening, and offering labor support. Delayed pushing increases the length of the second stage of labor and does not affect the rate of spontaneous vaginal delivery. A tight nuchal cord can be clamped twice and cut before delivery of the shoulders, or the baby may be delivered using a somersault maneuver in which the cord is left nuchal and the distance from the cord to placenta minimized by pushing the head toward the maternal thigh. After delivery, skin-to-skin contact with the mother is recommended. Beyond 35 weeks' gestation, there is no benefit to bulb suctioning the nose and mouth. Postpartum maternal and neonatal outcomes can be improved through delayed cord clamping, active management to prevent postpartum hemorrhage, careful examination for external anal sphincter injuries, and use of absorbable synthetic suture for second-degree perineal laceration repair. Practices that will not improve outcomes and may result in negative outcomes include discontinuation of epidurals late in labor and routine episiotomy. PMID:26280140

    Childbirth is an important event in a womans life. Vaginal childbirth is the most common mode of delivery and it has been associated with increased incidence of pelvic floor disorders later in life. In this article, the authors review and summarize current literature associating pelvic floor disorders with vaginal childbirth. Stress urinary incontinence and pelvic organ prolapse are strongly associated with vaginal childbirth and parity. The exact mechanism of injury associating vaginal delivery with pelvic floor disorders is not known, but is likely multifactorial, potentially including mechanical and neurovascular injury to the pelvic floor. Observational studies have identified certain obstetrical exposures as risk factors for pelvic floor disorders. These factors often coexist in clusters; hence, the isolated effect of these variables on the pelvic floor is difficult to study. PMID:23638782

    1982-10-01

    Plasma samples and biopsies of vaginal tissue were obtained from 23 healthy women undergoing operative sterilization, 1 to 6 h after a single oral dose of ketoconazole 200 mg. Drug concentrations in plasma and tissue, were measured by a specific gas chromatographic method. The vaginal tissue concentration averaged 2.4 times less than the corresponding plasma levels. Equilibrium between tissue, and plasma was established within 1 h after dosing, when vaginal tissue levels exceeded 1 microgram/g. Ketoconazole concentrations decayed monoexponentially over the time interval studied (1-6h), with the similar half-lives of 1.2 and 1.4 H in plasma and tissue, respectively. Following an oral 200 mg dose, a tissue concentration not less than 0.01 microgram/ml was maintained over a 12 h period. This concentration has been shown to prevent outgrowth of the invasive (pseudo) mycelial form of Candida albicans. Hence, a b.i.d. or t.i.d. dosage schedule of ketoconazole in vaginal candidosis would give continuously effective levels at the site of infection. Ketoconazole concentrations in vaginal fluid are thought to be much higher than in the tissue because of ion-trapping. The present data may explain the efficacy of oral ketoconazole in the treatment of vaginal candidosis. PMID:6293835

    PubMed

    Posterior vaginal wall prolapse is one of the most common prolapses encountered by gynecological surgeons. What appears to be a straightforward condition to diagnose and treat surgically for physicians has proven to be frustratingly unpredictable with regard to symptom relief for patients. Functional disorders such as dyssynergic defecation and constipation are often attributed to posterior vaginal wall prolapse. Little scientific evidence supports this assumption, emphasizing that structure and function are not synonymous when treating posterior vaginal wall prolapse. Rectoceles, enteroceles, sigmoidoceles, peritoneoceles, rectal and intraanal intussusception, rectal prolapse, and descending perineal syndrome are all conditions that have an impact on the posterior vaginal wall. All too often these different anatomic conditions are treated with the same surgical approach, addressing a posterior vaginal wall bulge with a traditional posterior colporrhaphy. Studies that examine the correlation between stage of posterior wall prolapse and patient symptoms have failed to reliably do so. Surgical outcomes measured by prolapse staging appear successful, yet patient expectations are often not met. As increasing attention is being placed on patient satisfaction outcomes concerning surgical treatments, this fact will need to be addressed. Surgeons will have to clearly communicate what can and what cannot be expected with surgical repair of posterior vaginal wall prolapse. PMID:26348375

    Studying the vaginal microflora is not only fascinating, with many discoveries to be made, it is also a very practical way to help women get rid of bothersome and sometimes dangerous infections. Gram-stained vaginal preparations, Pap smears, specific cultures, and nucleic acid detection techniques can be used to diagnose the constituents of the vaginal flora, but in trained hands office-based microscopy of a fresh vaginal smear, preferably using a x400 magnification phase-contrast microscope, allows almost every diagnosis and combination of diagnoses imaginable. In this chapter I will address the pros and cons of the tools that are in use to study vaginal flora, and discuss the different types of bacterial flora and the difficulties encountered in reaching the correct diagnosis of pathological conditions. The 'intermediate flora' is addressed separately, and a new entity--'aerobic vaginitis'--is discussed. Future research should focus on the interaction between infecting microorganisms and host defence mechanisms, as both together generate the pathogenicity of these conditions. PMID:17434799

Material and methods Eighty women with asymptomatic utero-vaginal prolapse were included in this prospective study for vaginal hysterectomy after preoperative preparation and after written informed consent. Women included in this study were screened preoperatively by high vaginal swab, Pap smear, endometrial biopsy and trans-vaginal ultrasound. Surgically removed uteri and ovaries were sent for histopathological examination. Results of histopathological examination as gold standard were compared with conventional gynecological screening methods. Results Histopathological examination of surgically removed uteri and ovaries after vaginal hysterectomy for uterovaginal prolapse showed abnormal findings in 61.25% (49/80) of studied cases (10 chronic cervicitis; 20 cervical intra-epithelial neoplasia-1 [CIN-1]; 5 CIN-2; 2 CIN-3; 10 simple endometrial hyperplasia without atypia and 2 simple serous ovarian cyst). Also, histopathological examination showed premalignant changes in 33.75% (27/80) of studied cases (20 CIN-1; 5 CIN-2 and 2 CIN-3), which mean 50% sensitivity of pre-operative Pap smear to detect premalignant cervical changes. Conclusions Asymptomatic women with utero-vaginal prolapse may have associated premalignant lesions which may not be detected by conventional screening methods, and this should be explained preoperatively for women undergoing surgery, especially if conservative management was considered.

    The opening of the mouse vaginal cavity to the skin is a postnatal tissue remodeling process that occurs at approximately five weeks of age for the completion of female genital tract maturation at puberty. The tissue remodeling process is primarily composed of a hormonally triggered apoptotic process predominantly occurring in the epithelium of the distal section of the vaginal cavity. However, the detailed mechanism underlying the apoptotic induction remains to be elucidated. In the present study, it was observed that the majority of BALB/c mice lacking the class 4 semaphorin, semaphorin 4D (Sema4D), developed imperforate vagina and hydrometrocolpos resulting in a perpetually unopened vaginal cavity regardless of a normal estrogen level comparable with that in wild‑type (WT) mice. Administration of β‑estradiol to infant Sema4D‑deficient (Sema4D‑/‑) mice did not induce precocious vaginal opening, which was observed in WT mice subjected to the same β‑estradiol administration, excluding the possibility that the closed vaginal phenotype was due to insufficient estrogen secretion at the time of vaginal opening. In order to assess the role of Sema4D in the postnatal vaginal tissue remodeling process, the expression of Sema4D and its receptor, plexin‑B1, was examined as well as the level of apoptosis in the vaginal epithelia of five‑week‑old WT and Sema4D‑/‑ mice. Immunohistochemical analyses confirmed the localization of Sema4D and plexin‑B1 in the mouse vaginal epithelia. Terminal deoxynucleotidyl transferase dUTP nick end labeling assay and immunohistochemistry detecting activated caspase‑3 revealed significantly fewer apoptotic cells in situ in the vaginal mucosa of five‑week‑old Sema4D‑/‑ mice compared with WT mice. The addition of recombinant Sema4D to Sema4D‑/‑ vaginal epithelial cells in culture significantly enhanced apoptosis of the vaginal epithelial cells, demonstrating the apoptosis‑inducing activity of Sema4D. The experimental reduction of plexin‑B1 expression in vaginal epithelial cells demonstrated the integral role of plexin‑B1 in Sema4D‑induced apoptotic cell death. These results suggest a non‑redundant role of Sema4D in the postnatal tissue remodeling process in five‑week‑old BALB/c mice, which involves the induction of vaginal epithelial cell apoptosis through Sema4D binding to plexin‑B1.

    Petereit DG, Tannehill SP, Grosen EA, Hartenbach EM, Schink JC. Outpatient vaginal cuff brachytherapy for endometrial cancer. The objective of this study was to determine the efficacy and complications of postoperative high-dose-rate (HDR) vaginal-cuff brachytherapy (VCB) in patients with endometrial carcinoma. Between August 1989 to September 1997, 191 patients were treated postoperatively after a total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH/BSO) with outpatient adjuvant HDR VCB for low-risk endometrial cancer (IB-84%, grade 1 or 2-96%). Patients were treated with 2 HDR fractions, delivered one week apart while under conscious sedation (16.2 Gy X 2 to the vaginal surface). All clinical endpoints were calculated using the Kaplan Meier method. The median time in the brachytherapy suite was 60 min in which no acute complications were observed. The 30-day morbidity and mortality rates were both 0%. With a median follow-up of 38 months (12-82 months), the 4-year survival, relapse-free survival, and vaginal-control rates were 95%, 98%, and 100%, respectively. One patient developed a colo-vaginal fistula at 5 years. Adjuvant HDR VCB in 2 outpatient insertions produced 100% vaginal control rates with minimal morbidity. The advantages of high dose-rate compared to low dose-rate vaginal brachytherapy include patient convenience, markedly shorter treatment times (1 h per insertion), and reduction in the cost and potential morbidity of hospitalization. HDR brachytherapy approach is a cost-effective alternative to either low-dose-rate brachytherapy or whole pelvic radiotherapy in carefully selected patients. PMID:11240811

    To overview phytotherapy of vaginitis in order to identify new approaches for new pharmacological treatments. All related literature databases were searched for herbal medicinal treatment in vaginitis. The search terms were plant, herb, herbal therapy, phytotherapy, vaginitis, vaginal, anti-candida, anti-bacterial and anti-trichomonas. All of the human, animal and in vitro studies were included. Anti-candida, anti-bacterial and anti-trichomonas effects were the key outcomes. The plants including carvacrol, 1,8-cineole, geranial, germacrene-D, limonene, linalool, menthol, terpinen-4-ol and thymol exhibited anti-candida effects. A very low concentration of geranium oil and geraniol blocked mycelial growth, but not yeast. Tea tree oil including terpinen-4-ol, alpha-terpinene, gamma-terpinene and alpha-terpineol showed anti-bacterial, anti-fungal and anti-protozoal properties against trichomonas. Allium hirtifolium (persian shallot) comparable to metronidazole exhibited anti-trichomonas activity due to its components such as allicin, ajoene and other organosulfides. The plants having beneficial effects on vaginitis encompass essential oils that clear the pathway that future studies should be focused to standardize theses herbs. PMID:22514885

    Our objective was to determine the factors involved in the development of shoulder dystocia in association with operative vaginal delivery. In this prospective study, patients who were candidates for operative vaginal delivery were randomized either to forceps (N = 315) or vacuum with M-cup (N = 322) and timed from initial placement of instrument to final delivery. Data were gathered prior to and after instrumental delivery. Statistics used were Pearson chi square, Fisher's exact, analysis of variance, and multiple logistic regression. There were a total of 21 patients with shoulder dystocia in both groups (3.3% incidence). Discriminant factors that did nor meet significance included use of epidural analgesia (P = .12), station (P = .99), previous vaginal delivery (P = .99), fetal gender (P = .54), indication for operative vaginal delivery (P = .63), > 45 degrees rotation (P = .68), use of episiotomy (P = .62), maternal weight (P = .26), and maternal diabetes (P = .08). Nearly attaining significance in univariate analysis was randomization to vacuum (P = .052). Significant factors included gestational age (P = .03), time required to effect delivery (P = .007), and birthweight (P = .0001). When these factors were subjected to stepwise multiple logistic regression, three factors remained as significant associations with shoulder dystocia: randomization to vacuum (P = .04), time for delivery (P = .03), and birthweight (P = .0001). In this operative vaginal delivery trial, shoulder dystocia was strongly associated with large fetal size, longer time to delivery, and the use of vacuum for delivery. PMID:9260120

    Lactoferrin (LF) is one of the prebiotics present in the human body. A 38-year-old multiparous woman with poor obstetrical histories, three consecutive preterm premature rupture of membrane at the 19th, 23rd and 25th week of pregnancy, was referred to our hospital. She was diagnosed as having refractory vaginitis. Although estriol vaginal tablets were used for 4 months, the vaginitis was not cured. We administrated vaginal tablets and oral agents of prebiotic LF, resulting in a Lactobacillus predominant vaginal flora. When she was pregnant, she continued to use the LF, and the Lactobacillus in the vaginal flora was continuously observed during pregnancy. An elective cesarean section was performed at the 38th week of pregnancy. When the administration of LF was discontinued after the delivery, Lactobacillus in the vaginal flora was disappeared.

    Bacterial vaginosis (BV) is the most common vaginal disorder among reproductive age women. One clinical indicator of BV is a “fishy” odor. This odor has been associated with increases in several biogenic amines (BAs) that may serve as important biomarkers. Within the vagina, BA production has been linked to various vaginal taxa, yet their genetic capability to synthesize BAs is unknown. Using a bioinformatics approach, we show that relatively few vaginal taxa are predicted to be capable of producing BAs. Many of these taxa (Dialister, Prevotella, Parvimonas, Megasphaera, Peptostreptococcus, and Veillonella spp.) are more abundant in the vaginal microbial community state type (CST) IV, which is depleted in lactobacilli. Several of the major Lactobacillus species (L. crispatus, L. jensenii, and L. gasseri) were identified as possessing gene sequences for proteins predicted to be capable of putrescine production. Finally, we show in a small cross sectional study of 37 women that the BAs putrescine, cadaverine and tyramine are significantly higher in CST IV over CSTs I and III. These data support the hypothesis that BA production is conducted by few vaginal taxa and may be important to the outgrowth of BV-associated (vaginal dysbiosis) vaginal bacteria. PMID:26483694

    A 13 yr old female spayed Labrador retriever presented for vulvar bleeding. Abdominal radiographs revealed a soft tissue mass in the ventral pelvic canal. A computed tomography (CT) exam and a CT vaginourethrogram localized the mass to the vagina, helped further characterize the mass, and aided in surgical planning. A total vaginectomy was performed and the histologic diagnosis was leiomyoma. Vaginal tumors make up 1.9-3% of all tumors. Seventy-three percent of vaginal tumors are benign, and 83% of those are leiomyomas. Leiomyomas often have a good long-term prognosis with surgical resection. The diagnostic investigation of this case report utilized a multimodal imaging approach to determine the extent and respectability of the vaginal mass. To the best of the authors' knowledge, this is the first report describing a CT vaginourethrogram. PMID:24051257

    A skin and fascia flap from the medial thigh is proposed for vaginal and perineal reconstruction. Dissection, vascular injection, and radiographs of 20 fresh cadaver limbs uniformly demonstrated the presence of a communicating suprafascial vascular plexus in the medial thigh. Three to four nonaxial vessels were consistently found to enter the proximal plexus from within 5 cm of the perineum. Preservation of these vessels permitted reliable elevation of a 9 X 20 cm fasciocutaneous flap without using the gracilis muscle as a vascular carrier. Fifteen flaps in 13 patients were used for vaginal replacement and coverage of vulvectomy, groin, and ischial defects. Depending on the magnitude of the defect, simultaneous and independent elevation of the gracilis muscle provided additional vascularized coverage as needed. Our experience indicates that the medial thigh fasciocutaneous flap is a durable, less bulky, and potentially sensate alternative to the gracilis musculocutaneous flap for vaginal and perineal reconstruction.

    The vagina stands as an important alternative to the oral route for those systemic drugs that are poorly absorbed orally or are rapidly metabolized by the liver. Drug permeation through the vaginal tissue can be estimated by using in vitro, ex vivo and in vivo models. The latter ones, although more realistic, assume ethical and biological limitations due to animal handling. Therefore, in vitro and ex vivo models have been developed to predict drug absorption through the vagina while allowing for simultaneous toxicity and pathogenesis studies. This review focuses on available methodologies to study vaginal drug permeation discussing their advantages and drawbacks. The technical complexity, costs and the ethical issues of an available model, along with its accuracy and reproducibility will determine if it is valid and applicable. Therefore every model shall be evaluated, validated and standardized in order to allow for extrapolations and results presumption, and so improving vaginal drug research and stressing its benefits.

    Biofilm formation by nonpathogenic bacteria is responsible for their stable maintenance in vivo ecosystems as it promotes long-term permanence on the host's vaginal mucosa. Biofilm formation by Lactobacilli has been reported in vitro but not in vivo. We hypothesize the presence of biofilm formation in vivo could be also documented by microscope photographs (MP) of wet mounts obtained from uninfected vaginal samples satisfying rigorous scientific identification criteria. We analyzed 400 MP from our database, and we were able to determine that 12 MP from 6 different patients contained clues of the formation of biofilm by Lactobacilli. The most probable lactobacillus involved is presumed to be Lactobacillus jensenii. The documentation of biofilm formation by vaginal Lactobacilli at fresh wet mount preparation is significant and has several important clinical preventive and therapeutic implications. PMID:25725906

    Using solely a gene-based procedure, PCR amplification of the 16S ribosomal RNA gene coupled with very deep sequencing of the amplified products, the microbes on 20 human vaginal epithelia of healthy women have been identified and quantitated. The Lactobacillus content on these 20 healthy vaginal epithelia was highly variable, ranging from 0% to 100%. For four subjects, Lactobacillus was (virtually) the only bacterium detected. However, that Lactobacillus was far from clonal and was a mixture of species and strains. Eight subjects presented complex mixtures of Lactobacillus and other microbes. The remaining eight subjects had no Lactobacillus. Instead, Bifidobacterium, Gardnerella, Prevotella, Pseudomonas, or Streptococcus predominated. PMID:15911771

    Background Vaginal atrophy is a chronic condition with symptoms that include vaginal dryness, pain during sex, itching, irritation, burning, and discharge, as well as various urinary problems. Up to 45% of postmenopausal women may be affected, but it often remains underreported and undertreated. This article aims to review the current recommendations for treatment of vaginal atrophy, and current data on the effectiveness and safety of local vaginal estrogen therapies. Methods Literature regarding vaginal atrophy (20072012) was retrieved from PubMed and summarized, with emphasis on data related to the treatment of vaginal atrophy with local vaginal estrogen therapy. Results Published data support the effectiveness and endometrial safety of low-dose local estrogen therapies. These results further support the general recommendation by the North American Menopause Society that a progestogen is not needed for endometrial protection in patients using low-dose local vaginal estrogen. Benefits of long-term therapy for vaginal atrophy include sustained relief of symptoms as well as physiological improvements (eg, decreased vaginal pH and increased blood flow, epithelial thickness, secretions). Conclusion Currently available local vaginal estrogen therapies are well tolerated and effective in relieving symptoms of vaginal atrophy. Recent data support the endometrial safety of low-dose regimens for up to 1 year. PMID:24648775

    ABSTRACT Vaginal inflammation (vaginitis) is the most common disease caused by the human-pathogenic fungus Candida albicans. Secretory aspartyl proteinases (Sap) are major virulence traits of C.albicans that have been suggested to play a role in vaginitis. To dissect the mechanisms by which Sap play this role, Sap2, a dominantly expressed member of the Sap family and a putative constituent of an anti-Candida vaccine, was used. Injection of full-length Sap2 into the mouse vagina caused local neutrophil influx and accumulation of the inflammasome-dependent interleukin-1? (IL-1?) but not of inflammasome-independent tumor necrosis factor alpha. Sap2 could be replaced by other Sap, while no inflammation was induced by the vaccine antigen, the N-terminal-truncated, enzymatically inactive tSap2. Anti-Sap2 antibodies, in particular Fab from a human combinatorial antibody library, inhibited or abolished the inflammatory response, provided the antibodies were able, like the Sap inhibitor Pepstatin A, to inhibit Sap enzyme activity. The same antibodies and Pepstatin A also inhibited neutrophil influx and cytokine production stimulated by C.albicans intravaginal injection, and a mutant strain lacking SAP1, SAP2, and SAP3 was unable to cause vaginal inflammation. Sap2 induced expression of activated caspase-1 in murine and human vaginal epithelial cells. Caspase-1 inhibition downregulated IL-1? and IL-18 production by vaginal epithelial cells, and blockade of the IL-1? receptor strongly reduced neutrophil influx. Overall, the data suggest that some Sap, particularly Sap2, are proinflammatory proteins in vivo and can mediate the inflammasome-dependent, acute inflammatory response of vaginal epithelial cells to C.albicans. These findings support the notion that vaccine-induced or passively administered anti-Sap antibodies could contribute to control vaginitis. PMID:26037125

    The widespread occurrence of vaginal candidiasis and the development of resistance against anti-fungal agents has stimulated interest in understanding the pathogenesis of this disease. The aim of our work was to characterize, in an animal model of vaginal candidiasis, the mechanisms that play a role in the induction of mucosal immunity against C. albicans and the interaction between innate and adaptive immunity. Our studies evidenced the elicitation of cell-mediated immunity (CMIs) and antibody (Abs)-mediated immunity with a Th1 protective immunity. An immune response of this magnitude in the vagina was very encouraging to identify the proper targets for new strategies for vaccination or immunotherapy of vaginal candidiasis. Overall, our data provide clear evidence that it is possible to prevent C. albicans vaginal infection by active intravaginal immunization with aspartyl proteinase expressed as recombinant protein. This opens the way to a modality for anti-Candida protection at the mucosa. The recombinant protein Sap2 was assembled with virosomes, and a vaccine PEVION7 (PEV7) was obtained. The results have given evidence that the vaccine, constituted of virosomes and Secretory aspartyl proteinase 2 (Sap2) (PEV7), has an encouraging therapeutic potential for the treatment of recurrent vulvovaginal candidiasis.

    Vaginal lactobacilli provide protection against intrusive pathogenic bacteria. Some Lactobacillus spp. produce in vitro a thick, protective biofilm. We report in vivo formation of biofilm by vaginal Lactobacillus jensenii. The biofilm formation was captured in fresh wet-mount microscopic samples from asymptomatic patients after treatment for recurrent bacterial vaginitis. In vivo documentation of biofilm formation is in our opinion noteworthy, and has significant clinical implications, among which are the possibility to isolate, grow, and therapeutically utilize lactobacilli to prevent recurrent vaginal infections and preterm labor associated with vaginal microbial pathogens.

    The aim of this work is to evaluate the in vitro microbicidal activity of vaginal suppositories (VS) containing tea tree oil (TTO-VS) towards Candida spp. and vaginal probiotics. A total of 20 Candida spp. strains, taken from patients with vaginitis and from an established type collection, including reference strains, were analysed by using the CLSI microdilution method. To study the action of VS towards the beneficial vaginal microbiota, the sensitivity of Bifidobacterium animalis subsp. lactis (DSM 10140) and Lactobacillus spp. (Lactobacillus casei R-215 and Lactobacillus acidophilus R-52) was tested. Both TTO-VS and TTO showed fungicidal activity against all strains of Candida spp. whereas placebo-VS or the Aloe gel used as controls were ineffective. The study of fractional fungicidal concentrations (FFC) showed synergistic interaction with the association between Amphotericin B and TTO (0.25 to 0.08 µg/ml, respectively) against Candida albicans. Instead, the probiotics were only affected by TTO concentration ≥ 4% v/v, while, at concentrations < 2% v/v, they remained viable. TTO-VS exhibits, in vitro, a selective fungicidal action, slightly affecting only the Bifidobacteriun animalis strain growth belonging to the vaginal microbiota. In vivo studies are needed to confirm the efficacy to prevent acute or recurrent vaginal candidiasis. PMID:26235937

    2015-01-01

    Management of breast cancer includes systematic therapies including chemotherapy and endocrine therapy can lead to a variety of symptoms that can impair the quality of life of many breast cancer survivors. Atrophic vaginitis, caused by decreased levels of circulating estrogen to urinary and vaginal receptors, is commonly experienced by this group. Chemotherapy induced ovarian failure and endocrine therapies including aromatase inhibitors and selective estrogen receptor modulators can trigger the onset of atrophic vaginitis or exacerbate existing symptoms. Symptoms of atrophic vaginitis include vaginal dryness, dyspareunia, and irritation of genital skin, pruritus, burning, vaginal discharge, and soreness. The diagnosis of atrophic vaginitis is confirmed through patient-reported symptoms and gynecological examination of external structures, introitus, and vaginal mucosa. Lifestyle modifications can be helpful but are usually insufficient to significantly improve symptoms. Non-hormonal vaginal therapies may provide additional relief by increasing vaginal moisture and fluid. Systemic estrogen therapy is contraindicated in breast cancer survivors. Continued investigations of various treatments for atrophic vaginitis are necessary. Local estrogen-based therapies, DHEA, testosterone, and pH-balanced gels continue to be evaluated in ongoing studies. Definitive results are needed pertaining to the safety of topical estrogens in breast cancer survivors. PMID:25815692

    Trichomonas vaginalis and Tritrichomonas foetus cause common sexually transmitted infections in humans and cattle, respectively. Mouse models of trichomoniasis are important for pathogenic and therapeutic studies. Here, we compared murine genital infections with T. vaginalis and T. foetus. Persistent vaginal infection with T. foetus was established with 100 parasites but T. vaginalis infection required doses of 10(6), perhaps because of greater susceptibility to killing by mouse vaginal polymorphonuclear leukocytes. Infection with T. vaginalis persisted longest after combined treatment of mice with estrogen and dexamethasone, whereas infection was only short-lived when mice were given estrogen or dexamethasone alone, co-infected with Lactobacillus acidophilus, and/or pretreated with antibiotics. Infection rates were similar with metronidazole-resistant (MR) and metronidazole-sensitive (MS) T. vaginalis. High dose but not low dose metronidazole treatment controlled infection with MS better than MR T. vaginalis. These murine models will be valuable for investigating the pathogenesis and treatment of trichomoniasis. PMID:21976570

    Introduction Vaginal douching is a widespread practice among American women. Little research has been done examining variation in the practice or identifying risk factors. Methods We collected data on douching, as well as hypothesized predictors of vaginal douching, as part of a cohort study on preterm birth. African-American women residing in Baltimore City, Maryland, were enrolled if they received prenatal care or delivered at The Johns Hopkins Medical Institution. Interview data were collected on 872 women between March 2001 and July 2004, with a response rate of 68%. Logistic regression analysis was selected to identify factors associated with douching in the 6 months prior to pregnancy. Results Almost two thirds of women reported ever douching and more than two thirds of those women reported douching in the 6 months prior to pregnancy. Variation was seen in the practice of douching with regard to frequency as well as technique. After adjusting for several confounders, prenatal enrollment (odds ratio [OR], 1.80; 95% confidence interval [CI], 1.29, 2.53), more unmet needs for time for nonessentials (OR, 1.83; 95% CI, 1.27, 2.63), smoking in the year prior to the birth (OR, 1.78; 95% CI, 1.22, 2.60), and age > 19 years (OR, 2.60; 95% CI, 1.36, 4.97) were significant predictors of douching in the 6 months prior to pregnancy. Discussion We identified considerable heterogeneity in the practice of vaginal douching in a cohort of low income African-American women. Conclusions Future studies should incorporate measures of the predictors of douching and detailed exposure information to determine the independent contribution of vaginal douching to health outcomes.

    Infections of the vulva and vagina are one of the most common gynecological diseases. They can be determined by a variety of physical, chemical and biological factors. The main risk factors contributing to vaginitis are aerobic and anaerobic bacterias, fungal and viral infections, and irritants. Subjective complaints are pruritus, vulvar and/or perivulvar erytema and different in volume and characterization discharge. Excepting etiological treatment in most cases it is necessary to use additional agents, for example Saforelle. PMID:26817249

    The concentration of IgG, IgA and IgM has been measured in the cervico-vaginal secretions of 8 women with a normal menstrual cycle, 52 pregnant women, 6 post-menopausal women and 12 women with total hysterectomy. No significant difference in immunoglobulin levels was found in the cervico-vaginal secretions of women with a normal cycle as compared to those of post-menopausal or pregnant women. A significant decrease of the IgG/IgA ratio was noticed during ovulation as a consequence of increased IgA secretion. In patients with hysterectomy, the secretions are of vaginal origin only and contain negligible quantities of IgA. Secretory IgA is found essentially in the superior genital tract. IgM is present in trace amounts in all secretions and does not vary considerably. The secretion of immunoglobulins may be under hormonal control: in addition to ovarian hormones, corticosteroids seem also to be involved. The local application of a fluorinated corticosteroid into the vagina has produced a significant decrease of secretory IgA production. The therapeutic possibilities of administering a fluorinated corticosteroid in cases of sterility which are due to the production of anti-spermatozoal antibodies are discussed. PMID:558170

    Objective. To study the antimicrobial susceptibility of six vaginal probiotic lactobacilli. Methods. The disc diffusion method in Meller Hinton, LAPTg and MRS agars by the NCCLS (National Committee for Clinical Laboratory Standards) procedure was performed. Due to the absence of a Lactobacillus reference strains, the results were compared to those of Staphylococcus aureus ATCC29213. Minimal Inhibitory Concentration (MIC) with 21 different antibiotics in LAPTg agar and broth was also determined. Results. LAPTg and MRS agars are suitable media to study antimicrobial susceptibility of lactobacilli. However, the NCCLS procedure needs to be standardized for this genus. The MICs have shown that all Lactobacillus strains grew at concentrations above 10 ?g/mL of chloramphenicol, aztreonam, norfloxacin, ciprofloxacin, ceftazidime, ceftriaxone, streptomycin and kanamycin. Four lactobacilli were sensitive to 1 ?g/mL vancomycin and all of them were resistant to 1000 ?g/mL of metronidazole. Sensitivity to other antibiotics depended on each particular strain. Conclusions. The NCCLS method needs to be standardized in an appropriate medium to determine the antimicrobial susceptibility of Lactobacillus. Vaginal probiotic lactobacilli do not display uniform susceptibility to antibiotics. Resistance to high concentrations of metronidazole suggests that lactobacilli could be simultaneously used with a bacterial vaginosis treatment to restore the vaginal normal flora. PMID:17485797

    ABSTRACT The objective of this study was to compare the effects of systemic and local estrogen treatment on collagen assembly and biomechanical properties of the vaginal wall. Ovariectomized nulliparous rats were treated with estradiol or conjugated equine estrogens (CEEs) either systemically, vaginal CEE, or vaginal placebo cream for 4 wk. Low-dose local CEE treatment resulted in increased vaginal epithelial thickness and significant vaginal growth without uterine hyperplasia. Furthermore, vaginal wall distensibility increased without compromise of maximal force at failure. Systemic estradiol resulted in modest increases in collagen type I with no change in collagen type III mRNA. Low-dose vaginal treatment, however, resulted in dramatic increases in both collagen subtypes whereas moderate and high dose local therapies were less effective. Consistent with the mRNA results, low-dose vaginal estrogen resulted in increased total and cross-linked collagen content. The inverse relationship between vaginal dose and collagen expression may be explained in part by progressive downregulation of estrogen receptor-alpha mRNA with increasing estrogen dose. We conclude that, in this menopausal rat model, local estrogen treatment increased total and cross-linked collagen content and markedly stimulated collagen mRNA expression in an inverse dose-effect relationship. High-dose vaginal estrogen resulted in downregulation of estrogen receptor-alpha and loss of estrogen-induced increases in vaginal collagen. These results may have important clinical implications regarding the use of local vaginal estrogen therapy and its role as an adjunctive treatment in women with loss of vaginal support.

    Background. The FDA approved over-the-counter (OTC) use of vaginal antifungals in 1990. Subsequently, a plethora of OTC products have become available to women on drugstore shelves. Objectives. The purpose of this study was to determine the availability of OTC products marketed for the treatment of vaginitis and to determine if their efficacy had been confirmed by published prospective randomized control trials (RCTs). Materials and methods. The authors chose four retail locations frequented by women seeking vaginitis treatment. All products deemed a viable treatment option were purchased. Results. All intravaginal imidazoles purchased, regardless of treatment duration or active ingredient, were found to be of proven efficacy. We were unable to find an RCT confirming the effectiveness of vaginal anti-itch creams and homeopathic treatments for vaginitis. Conclusion. 45% of products available to women in the feminine hygiene section of the stores surveyed could not be confirmed to be effective for treating infectious vaginitis. PMID:18253469

    Background: Vaginitis, is an infectious inflammation of the vaginal mucosa, which sometimes involves the vulva. The balance of the vaginal flora is maintained by the Lactobacilli and its protective and probiotic role in treating and preventing vaginal infection by producing antagonizing compounds which are regarded as safe for humans. Aim: The aim of this study was to evaluate the protective role of Lactobacilli against common bacterial opportunistic pathogens in vaginitis and study the effects of some antibiotics on Lactobacilli isolates. Materials and Methods: In this study (110) vaginal swabs were obtained from women suffering from vaginitis who admitted to Babylon Hospital of Maternity and Paediatrics in Babylon province, Iraq. The study involved the role of intrauterine device among married women with vaginitis and also involved isolation of opportunistic bacterial isolates among pregnant and non pregnant women. This study also involved studying probiotic role of Lactobacilli by production of some defense factors like hydrogen peroxide, bacteriocin, and lactic acid. Results: Results revealed that a total of 130 bacterial isolates were obtained. Intrauterine device was a predisposing factor for vaginitis. The most common opportunistic bacterial isolates were Staphylococcus aureus, Escherichia coli, Streptococcus agalactiae, and Klebsiella pneumoniae. All Lactobacilli were hydrogen peroxide producers while some isolates were bacteriocin producers that inhibited some of opportunistic pathogens (S. aureus, E. coli). Lactobacilli were sensitive to erythromycin while 93.3% of them were resistant to ciprofloxacin and (40%, 53.3%) of them were resistant to amoxicillin and gentamycin respectively. Results revealed that there was an inverse relationship between Lactobacilli presence and organisms causing vaginitis. This may be attributed to the production of defense factors by Lactobacilli. Conclusion: The types of antibiotics used to treat vaginitis must be very selective in order not to kill the beneficial bacteria (Lactobacilli) that help in preservation of vaginal health and ecosystem as being one of the probiotic bacteria.

    2011-01-01

    Vulvovaginal candidiasis (VVC), caused by Candida species, is a fungal infection of the lower female genital tract that affects approximately 75% of otherwise healthy women during their reproductive years18,32-34. Predisposing factors include antibiotic usage, uncontrolled diabetes and disturbance in reproductive hormone levels due to pregnancy, oral contraceptives or hormone replacement therapies33,34. Recurrent VVC (RVVC), defined as three or more episodes per year, affects a separate 5 to 8% of women with no predisposing factors33. An experimental mouse model of VVC has been established and used to study the pathogenesis and mucosal host response to Candida3,4,11,16,17,19,21,25,37. This model has also been employed to test potential antifungal therapies in vivo13,24. The model requires that the animals be maintained in a state of pseudoestrus for optimal Candida colonization/infection6,14,23. Under such conditions, inoculated animals will have detectable vaginal fungal burden for weeks to months. Past studies show an extremely high parallel between the animal model and human infection relative to immunological and physiological properties3,16,21. Differences, however, include a lack of Candida as normal vaginal flora and a neutral vaginal pH in the mice. Here, we demonstrate a series of key methods in the mouse vaginitis model that include vaginal inoculation, rapid collection of vaginal specimens, assessment of vaginal fungal burden, and tissue preparations for cellular extraction/isolation. This is followed by representative results for constituents of vaginal lavage fluid, fungal burden, and draining lymph node leukocyte yields. With the use of anesthetics, lavage samples can be collected at multiple time points on the same mice for longitudinal evaluation of infection/colonization. Furthermore, this model requires no immunosuppressive agents to initiate infection, allowing immunological studies under defined host conditions. Finally, the model and each technique introduced here could potentially give rise to use of the methodologies to examine other infectious diseases of the lower female genital tract (bacterial, parasitic, viral) and respective local or systemic host defenses.

    Vaginal foreign bodies are a complaint occasionally encountered in pediatric clinics and emergency departments, and when pediatric patients present with a vaginal foreign body sexual abuse may not be considered. We describe two children with vaginal foreign bodies who were found to have been sexually abused. Each child had a discharge positive for a sexually transmitted infection despite no disclosure or allegation of abuse. We recommend that all pre-pubertal girls who present with a vaginal foreign body should be considered as possible victims of sexual abuse and should receive a sexual abuse history and testing for sexually transmitted infections.

    Primary vaginal adenocarcinoma unrelated to intrauterine hormone exposure is very uncommon. We report a case of a 52-year-old woman who presented with primary vaginal adenocarcinoma that showed intestinal differentiation with prominent papillary formations and numerous papillary and villous features with prominent goblet cells. There was vaginal adenosis in the immediate vicinity of the tumor. To our knowledge, this is the first reported case of a primary vaginal adenocarcinoma of the intestinal type associated with adenosis in a patient unexposed to prenatal diethylstilbesterol.

    Vaginal evisceration is a rare condition most commonly associated with previous vaginal surgery. It usually presents with vaginal bleeding, lower abdominal pain and a protruding mass, and requires immediate assessment and surgical management to salvage the prolapsed bowel. Any delay in the treatment may result in bowel ischaemia and perforation which is associated with higher morbidity and mortality. We report a case of spontaneous vaginal evisceration during defaecation in a 56-year-old postmenopausal women 11?months post hysterectomy. This case highlights the benefits of a combined laparoscopic and transvaginal approach in the successful management of this surgical emergency. PMID:23667228

    Objective: To assess the results and contributions of laparoscopy in the management of postoperative bleeding following laparoscopic (LH) or vaginal hysterectomy (VH). Methods: A retrospective study of a 5-year period was carried out on 1167 women who underwent laparoscopic or vaginal hysterectomy. Ten women with postoperative bleeding following laparoscopic or vaginal hysterectomy were identified. Results: The overall incidence of bleeding after laparoscopic or vaginal hysterectomy was 0.85% (10 of 1167). Over the 5-year study period, the incidence fluctuated between 1.1% and 0.4%. Surgical revision was primarily vaginal in 1 woman, followed by laparoscopic control. In 6 patients, laparoscopy was performed immediately. The patients profited from the prompt laparoscopic treatment, because intraabdominal hemorrhage was found and stopped. Of 6 cases of intraperitoneal bleeding, 1 resulted from a blood disorder. The collagen-fibrin agent TachoComb was applied locally, and the patient was postoperatively treated with blood products and coagulation factors. Only bipolar coagulation, TachoComb, and Foley catheter were used to achieve local hemostasis during laparoscopy. The remaining 3 cases where the vaginal cuff was bleeding were managed by vaginal repair and packing without laparoscopy. Conclusion: The laparoscopic approach to postoperative bleeding following laparoscopic or vaginal hysterectomy is an attractive alternative to the abdominal surgical approach. Bleeding following laparoscopic or vaginal hysterectomy can be managed by laparoscopy in the majority of patients. Because the abdominal incision is avoided, the recovery time is reduced.

    The study aim is to evaluate the efficacy and safety of two low-dose vaginal estrogen treatments (ETs) and of a non-hormonal vaginal moisturizer in postmenopausal breast cancer survivors with urogenital atrophy. Eighteen patients receiving estriol cream 0.25 mg (n = 10) or estradiol tablets 12.5 microg (n = 8) twice/week for 12 weeks were evaluated and compared with eight patients treated with polycarbophil-based moisturizer 2.5 g twice/week. Severity of vaginal atrophy was assessed using subjective [Vaginal Symptoms Score (VSS), Profile of Female Sexual Function (PFSF)] and objective [Vaginal Health Index (VHI), Karyopycnotic Index (KI)] evaluations, while safety by measuring endometrial thickness and serum sex hormones levels. After 4 weeks, VSS and VHI were significantly improved by both vaginal ETs, with further improvement after 12 weeks. PFSF improved significantly only in estriol group (p = 0.02). Safety measurements did not significantly change. Vaginal moisturizer improved VSS at week 4 (p = 0.01), but score returned to pre-treatment values at week 12; no significant modification of VHI, KI, PFSF was recorded. Both low-dose vaginal ET are effective for relieving urogenital atrophy, while non-hormonal moisturizer only provides transient benefit. The increase of serum estrogens levels during treatment with vaginal estrogen at these dosages is minimal. PMID:20196634

    Study Objective: The aim of this study was to estimate the cumulative incidence of vaginal cuff dehiscence in robotic-assisted total hysterectomies in our patients and to provide recommendations to decrease the incidence of vaginal cuff dehiscence. Methods: This was an observational case series, Canadian Task Force Classification II-3 conducted at an academic and community teaching hospital. A total of 654 patients underwent robotic-assisted total laparoscopic hysterectomy for both malignant and benign reasons from September 1, 2006 to March 1, 2011 performed by a single surgeon. The da Vinci Surgical System was used for robotic-assisted total laparoscopic hysterectomy. Results: There were 3 cases of vaginal cuff dehiscence among 654 robotic-assisted total laparoscopic hysterectomies, making our cumulative incidence of vaginal cuff dehiscence 0.4%. The mean time between the procedures and vaginal cuff dehiscence was 44.3 d (6.3 wk). All patients were followed up twice after surgery, at 3 to 4 wk and 12 to 16 wk. Conclusion: In our study, the incidence of vaginal cuff dehiscence after robotic-assisted total laparoscopic hysterectomy compares favorably to that of total abdominal and vaginal hysterectomy. Our study suggests that the incidence of vaginal cuff dehiscence is more likely related to the technique of colpotomy and vaginal cuff suturing than to robotic-assisted total hysterectomy per se. With proper technique and patient education, our vaginal dehiscence rate has been 0.4%, which is 2.5 to 10 times less than the previously reported vaginal cuff dehiscence rate in the literature.

    The means by which vaginal microbiomes help prevent urogenital diseases in women and maintain health are poorly understood. To gain insight into this, the vaginal bacterial communities of 396 asymptomatic North American women who represented four ethnic groups (white, black, Hispanic, and Asian) were sampled and the species composition characterized by pyrosequencing of barcoded 16S rRNA genes. The communities clustered into five groups: four were dominated by Lactobacillus iners, L. crispatus, L. gasseri, or L. jensenii, whereas the fifth had lower proportions of lactic acid bacteria and higher proportions of strictly anaerobic organisms, indicating that a potential key ecological function, the production of lactic acid, seems to be conserved in all communities. The proportions of each community group varied among the four ethnic groups, and these differences were statistically significant [χ2(10) = 36.8, P < 0.0001]. Moreover, the vaginal pH of women in different ethnic groups also differed and was higher in Hispanic (pH 5.0 ± 0.59) and black (pH 4.7 ± 1.04) women as compared with Asian (pH 4.4 ± 0.59) and white (pH 4.2 ± 0.3) women. Phylotypes with correlated relative abundances were found in all communities, and these patterns were associated with either high or low Nugent scores, which are used as a factor for the diagnosis of bacterial vaginosis. The inherent differences within and between women in different ethnic groups strongly argues for a more refined definition of the kinds of bacterial communities normally found in healthy women and the need to appreciate differences between individuals so they can be taken into account in risk assessment and disease diagnosis.

    Objective This study aims to evaluate vaginal microbiota differences by bacterial vaginosis (BV), birth timing, and race, and to estimate parameters to power future vaginal microbiome studies. Methods Previously, vaginal swabs were collected at 21 to 25 weeks (stored at -80°C), and vaginal smears evaluated for BV (Nugent criteria). In a blinded fashion, 40 samples were selected, creating 8 equal-sized groups stratified by race (black/white), BV (present/absent), and birth timing (preterm/term). Samples were thawed, DNA extracted, and prepared. Polymerase chain reaction (PCR) with primers targeting the 16S rDNA V4 region was used to prepare an amplicon library. PCR products were sequenced and analyzed using quantitative insight into microbial ecology; taxonomy was assigned using ribosomal database program classifier (threshold 0.8) against the modified Greengenes database. Results After quality control, 97,720 sequences (mean) per sample, single-end 250 base-reads, were analyzed. BV samples had greater microbiota diversity (p < 0.05)-with BVAB1, Prevotella, and unclassified genus, Bifidobacteriaceae family (all p < 0.001) more abundant; there was minimal content of Gardnerella or Mobiluncus. Microbiota did not differ by race or birth timing, but there was an association between certain microbial clusters and preterm birth (p = 0.07). To evaluate this difference, 159 patients per group are needed. Conclusions There are differences in the vaginal microbiota between patients with and without BV. Larger studies should assess the relationship between microbiota composition and preterm birth. PMID:26479170

    This review focuses on two formulation approaches, mucoadhesion and thermogelling, intended for prolonging residence time on vaginal mucosa of medical devices or drug delivery systems, thus improving their efficacy. The review, after a brief description of the vaginal environment and, in particular, of the vaginal secretions that strongly affect in vivo performance of vaginal formulations, deals with the above delivery systems. As for mucoadhesive systems, conventional formulations (gels, tablets, suppositories and emulsions) and novel drug delivery systems (micro-, nano-particles) intended for vaginal administration to achieve either local or systemic effect are reviewed. As for thermogelling systems, poly(ethylene oxide-propylene oxide-ethylene oxide) copolymer-based and chitosan-based formulations are discussed as thermogelling systems. The methods employed for functional characterization of both mucoadhesive and thermogelling drug delivery systems are also briefly described. PMID:25683694

    The hormonal status of rats affected vaginal infection with Candida albicans. Four hours after infection viable counts were higher and germ tubes were longer in those animals in estrous than in other animals. However, the infection was not maintained with the change in epithelial cell type which occurred as part of the estrous cycle. Estrogen dosing following ovariectomy predisposed toward infection, while progesterone dosing did not. In rats injected with progesterone, germ tube clumping was seen, leukocytes were present, and elimination occurred before hyphal growth was evident. In rats injected with estrogen, however, infection was maintained, with hyphal growth extending throughout the cornified epithelial layer. Vaginal washings from rats dosed with estrogen promoted elongation of germ tubes in vitro to a greater extent than washings from other rats. Preincubation of blastospores in progesterone and subsequent infection of rats in pseudoestrous promoted clumping of germ tubes in the vagina. Strains of C. albicans varied in their virulence, which correlated with their ability to produce germ tubes in vitro. Loss of virulence occurred on subculture of a clinical isolate.

  7. Mucus-penetrating nanoparticles for vaginal and gastrointestinal drug delivery

    Ensign-Hodges, Laura

    A method that could provide more uniform and longer-lasting drug delivery to mucosal surfaces holds the potential to greatly improve the effectiveness of prophylactic and therapeutic approaches for numerous diseases and conditions, including sexually transmitted infections and inflammatory bowel disease. However, the body's natural defenses, including adhesive, rapidly cleared mucus linings coating nearly all entry points to the body not covered by skin, has limited the effectiveness of drug and gene delivery by nanoscale delivery systems. Here, we investigate the use of muco-inert mucus-penetrating nanoparticles (MPP) for improving vaginal and gastrointestinal drug delivery. Conventional hydrophobic nanoparticles strongly adhere to mucus, facilitating rapid clearance from the body. Here, we demonstrate that mucoadhesive polystyrene nanoparticles (conventional nanoparticles, CP) become mucus-penetrating in human cervicovaginal mucus (CVM) after pretreatment with sufficient concentrations of Pluronic F127. Importantly, the diffusion rate of large MPP did not change in F127 pretreated CVM, implying there is no affect on the native pore structure of CVM. Additionally, there was no increase in inflammatory cytokine release in the vaginal tract of mice after daily application of 1% F127 for one week. Importantly, HSV virus remains adherent in F127-pretreated CVM. Mucosal epithelia use osmotic gradients for fluid absorption and secretion. We hypothesized that hypotonically-induced fluid uptake could be advantageous for rapidly delivering drugs through mucus to the vaginal epithelium. We evaluated hypotonic formulations for delivering water-soluble drugs and for drug delivery with MPP. Hypotonic formulations markedly increased the rate at which drugs and MPP reached the epithelial surface. Additionally, hypotonic formulations greatly enhanced drug and MPP delivery to the entire epithelial surface, including deep into the vaginal folds (rugae) that isotonic formulations failed to reach. However, hypotonic formulations caused free drugs to be drawn through the epithelium, reducing vaginal retention. In contrast, hypotonic formulations caused MPP to accumulate rapidly and uniformly on vaginal surfaces, ideally positioned for sustained drug delivery. Using a mouse model of vaginal genital herpes (HSV-2) infection, we found that hypotonic delivery of free drug led to improved immediate protection, but diminished longer-term protection. Minimally hypotonic formulations provided rapid and uniform delivery of MPP to the entire vaginal surface, thus enabling formulations with minimal risk of epithelial toxicity. We then describe an ex vivo method for characterizing particle transport on freshly excised mucosal tissues. By directly observing MPP transport on vaginal, gastrointestinal, and respiratory tissue, we were able to determine an innate difference in mucus mesh size at different anatomical locations. In addition, we were able to optimize particle size for gastrointestinal delivery in mice. As described here, there are numerous barriers to effective drug delivery in the gastrointestinal tract, including the mucus barrier. We go on to demonstrate that MPP can improve delivery in the gastrointestinal tract, both by rectal and oral administration. Finally, we describe the use of MPP for improving vaginal drug delivery. Incomplete drug coverage and short duration of action limit the effectiveness of vaginally administered drugs, including microbicides for preventing sexually transmitted infections. We show that MPP provide uniform distribution over the vaginal epithelium, whereas CP are aggregated by mouse vaginal mucus, leading to poor distribution. By penetrating into the deepest mucus layers in the rugae, more MPP were retained in the vaginal tract compared to CP. After 24 h, when delivered in a conventional vaginal gel, patches of a model drug remained on the vaginal epithelium, whereas the epithelium was coated with drug delivered by MPP. We then demonstrate that when administered 30 min prior to inoculum, anti-HSV-2 MPP protected 53% of mice compared to only 16% protected by soluble drug. Overall, MPP improved vaginal drug distribution and retention, provided more effective protection against vaginal viral challenge than soluble drug, and were non-toxic when administered daily for one week.

    The presence of an abnormal vaginal microflora in early pregnancy is a risk factor for preterm delivery. There is no investigation on vaginal flora dominated by lactic acid bacteria and possible association with preterm delivery. We assessed the dominant vaginal Lactobacillus species in healthy pregnant women in early pregnancy in relation to pregnancy outcome. We observed 111 low risk pregnant women with a normal vaginal microflora 11 + 0 to 14 + 0 weeks of pregnancy without subjective complaints. Vaginal smears were taken for the identification of lactobacilli using denaturing gradient gel electrophoresis (DGGE). Pregnancy outcome was recorded as term or preterm delivery (limit 36 + 6 weeks of gestation). The diversity of Lactobacillus species in term vs. preterm was the main outcome measure. L. iners alone was detected in 11 from 13 (85%) women who delivered preterm. By contrast, L. iners alone was detected in only 16 from 98 (16%) women who delivered at term (p < 0.001). Fifty six percent women that delivered at term and 8% women that delivered preterm had two or more vaginal Lactobacillus spp. at the same time. This study suggests that dominating L. iners alone detected in vaginal smears of healthy women in early pregnancy might be associated with preterm delivery. PMID:24875844

    Background Product adherence is a pivotal issue in the development of effective vaginal microbicides to reduce sexual transmission of HIV. To date, the six Phase III studies of vaginal gel products have relied primarily on self-reporting of adherence. Accurate and reliable methods for monitoring user adherence to microbicide-releasing vaginal rings have yet to be established. Methods A silicone elastomer vaginal ring prototype containing an embedded, miniature temperature logger has been developed and tested in vitro and in cynomolgus macaques for its potential to continuously monitor environmental temperature and accurately determine episodes of ring insertion and removal. Results In vitro studies demonstrated that DST nano-T temperature loggers encapsulated in medical grade silicone elastomer were able to accurately and continuously measure environmental temperature. The devices responded quickly to temperature changes despite being embedded in different thickness of silicone elastomer. Prototype vaginal rings measured higher temperatures compared with a subcutaneously implanted device, showed high sensitivity to diurnal fluctuations in vaginal temperature, and accurately detected periods of ring removal when tested in macaques. Conclusions Vaginal rings containing embedded temperature loggers may be useful in the assessment of product adherence in late-stage clinical trials. PMID:25965956

    We performed a comparative study between abdominal and vaginal hysterectomies using clinical data from Al-Jamhouria hospital (one of the largest maternity hospitals in Eastern Libya). Various parameters were taken into consideration: the rates of each type (and their subtypes); average age of patients; indications; causes; postoperative complications; and duration of stay in the hospital afterwards. Conclusions and recommendations were drawn from the results of this study. In light of the aforementioned parameters, it was found that: (1) abdominal hysterectomies were more common than vaginal hysterectomies (p < 0.001); (2) patients admitted for abdominal hysterectomies are younger than those admitted for vaginal hysterectomies (p < 0.001); (3) the most common indication for an abdominal hysterectomy was menstrual disturbances, while for vaginal hysterectomies it was vaginal prolapse; (4) the histopathological cause for abdominal and vaginal hysterectomies were observed and the most common were found to be leiomyomas and atrophic endometrium; (5)there was no significant difference between the two routes in terms of postoperative complications; (6) patients who were admitted for abdominal hysterectomies spent a longer amount of time in the hospital (p < 0.01). It was concluded that efforts should be made to further pursue vaginal and laparoscopic hysterectomies as a viable option to the more conventional abdominal route. PMID:23919862

    Background We determined the prevalence of vaginal douching (cleansing of the vagina with liquid) in a sample of Cambodian women, and examined the associations of douching with genitourinary symptoms and infections, after controlling for potential confounding factors, including genitourinary symptoms and sociodemographic factors. Methods A total of 451 adolescent and adult females aged 15 to 49 years who attended 17 maternal and child health (MCH) clinics in 7 provinces of Cambodia in 2001 were consecutively enrolled as a part of the Sexually Transmitted Infection Sentinel Survey. Sociodemographic factors, genitourinary symptoms, and frequency of douching were assessed by face-to-face interviews using a structured questionnaire. Vaginal infections were examined by using standard diagnostic procedures specific to each pathogen. Results The proportion of participants who douched at least once a week was 76.7% (n = 346). Douching was significantly more prevalent in urban than in rural women (85.7%, n = 198 vs 67.3%, n = 148; P < 0.001). Frequency of douching was significantly associated with genitourinary symptoms, which were most prevalent in participants who douched from several times a week to once a day; genitourinary symptoms were less prevalent in those who douched more than once a day. Douching was significantly associated with vaginal candidiasis, but not with trichomoniasis or bacterial vaginosis, and this association persisted even after controlling for sociodemographic factors and genitourinary symptoms. Conclusions Vaginal douching was very common among Cambodian women visiting MCH clinics. Further investigations are warranted to elucidate the reasons for douching. In addition, women should be informed that douching may endanger their reproductive health. PMID:20009371

    The main objective of this work was to design thermosensitive and mucoadhesive vaginal hydrogels able to keep their rheological and mucoadhesive properties after dilution with vaginal fluids. Formulations were composed of pluronic F127 or a mix of two pluronics F127 and F68. Both formulations contained hydroxypropylmethyl cellulose (HPMC) as a mucoadhesive polymer. The determination of gelling temperature (T(gel)) after dilution with simulated vaginal fluid (SVF) demonstrated that hydrogels were resistant to dilution and T(gel) values were close to 30C. Ex vivo mucoadhesion experiments conducted on porcine vaginal mucosa founded on the technique of traction of the adhesive/adherent joint allowed the characterization of mucoadhesive properties of hydrogels by measuring work of adhesion (W) and maximum force of detachment (F(max)). In the case of F127-based hydrogels, W and F(max) were lowered after dilution with SVF. However, in the case of F127/F68-based hydrogels, W, F(max) and mucoadhesion profiles were weakly affected by dilution. These differences could be attributed to the higher elasticity of F127/F68/HPMC (22.5/2.5/1% w/w) hydrogel in comparison with F127/HPMC one (20/1% w/w). Indeed, rheological analyses of the formulations showed that both elastic (G') and viscous moduli (G'') were higher for F127/F68/HPMC (22.5/2.5/1% w/w) than for F127/HPMC hydrogel (20/1% w/w). However, we demonstrated that the higher elasticity of the hydrogel was due to the higher total pluronic concentration and not due to the presence of F68 in the formulation. PMID:20656027

    Background A contraceptive vaginal ring (CVR) containing Nestorone® (NES) and ethinyl estradiol (EE) that is reusable for 1- year (13 cycles) is under development. This study assessed effects of this investigational CVR on the incidence of vaginal infections and change in vaginal microflora. Methods There were 120 women enrolled into a NES/EE CVR Phase III trial and a microbiology sub-study for up to 1- year of cyclic product use. Gynecological examinations were conducted at baseline, the first week of cycle 6 and last week of cycle 13 (or during early discontinuation visits). Vaginal swabs were obtained for wet mount microscopy, Gram stain and culture. The CVR was removed from the vagina at the last study visit and cultured. Semi-quantitative cultures for Lactobacillus, Gardnerella vaginalis, Enterococcus faecalis, Staphylococcus aureus, Escherichia coli, anaerobic gram negative rods (GNRs), Candida albicans and other yeasts were performed on vaginal and CVR samples. Vaginal infections were documented throughout the study. Results Over 1- year of use, 3.3% of subjects were clinically diagnosed with bacterial vaginosis, 15.0% with vulvovaginal candidiasis, and 0.8% with trichomoniasis. The detection rate of these three infections did not change significantly from baseline to either Cycle 6 or 13. Nugent scores remained stable. H2O2-positive Lactobacillus dominated vaginal flora with a non-significant prevalence increase from 76.7% at baseline to 82.7% at cycle 6 and 90.2% at cycle 13, and a median concentration of 107 colony forming units (cfu) per gram. Although anaerobic GNRs prevalence increased significantly, the median concentration decreased slightly (104 to 103cfu per gram). There were no significant changes in frequency or concentrations of other pathogens. High levels of agreement between vaginal and ring surface microbiota were observed. Conclusion Sustained use of the NES/EE CVR did not increase the risk of vaginal infection and was not disruptive to the vaginal ecosystem.

    Purpose: To quantify the extent of interfractional vaginal cuff movement in patients receiving postoperative irradiation for cervical or endometrial cancer in the absence of bowel/bladder instruction. Methods and Materials: Eleven consecutive patients with cervical or endometrial cancer underwent placement of three gold seed fiducial markers in the vaginal cuff apex as part of standard of care before simulation. Patients subsequently underwent external irradiation and brachytherapy treatment based on institutional guidelines. Daily megavoltage CT imaging was performed during each external radiation treatment fraction. The daily positions of the vaginal apex fiducial markers were subsequently compared with the original position of the fiducial markers on the simulation CT. Composite dose-volume histograms were also created by summing daily target positions. Results: The average ({+-} standard deviation) vaginal cuff movement throughout daily pelvic external radiotherapy when referenced to the simulation position was 16.2 {+-} 8.3 mm. The maximum vaginal cuff movement for any patient during treatment was 34.5 mm. In the axial plane the mean vaginal cuff movement was 12.9 {+-} 6.7 mm. The maximum vaginal cuff axial movement was 30.7 mm. In the craniocaudal axis the mean movement was 10.3 {+-} 7.6 mm, with a maximum movement of 27.0 mm. Probability of cuff excursion outside of the clinical target volume steadily dropped as margin size increased (53%, 26%, 4.2%, and 1.4% for 1.0, 1.5, 2.0, and 2.5 cm, respectively.) However, rectal and bladder doses steadily increased with larger margin sizes. Conclusions: The magnitude of vaginal cuff movement is highly patient specific and can impact target coverage in patients without bowel/bladder instructions at simulation. The use of vaginal cuff fiducials can help identify patients at risk for target volume excursion.

    Estroprogestins with "natural oestrogen" has represented a new option in terms of combined hormonal contraception. So, the aim of this study is to investigate how estroprogestins with natural estrogen may modify the vaginal niche. In literature, very few studies focused on the interaction between hormonal contraception and vaginal milieu. This is a prospective comparative study. We enrolled 60 women from January 2013 to September 2013, 30 of them were administered estradiol valerate dienogest (E2V+DNG - Klaira®) in a quadriphasic regimen, while the other 30 women were administered 17-β estradiol with nomestrol acetate (EV+NOMAC - Zoely®) in a monophasic regimen. After a baseline study of vaginal milieu at recruitment of patients (Gram stain with Nugent score, vaginal pH, vaginal wet mount for the quantification of leukocytes, Lactobacilli and/or presence of Candida), we performed the same follow-up after six months of estroprogestin therapy. Our results showed that the women treated with E2V+DNG had a trend of an improvement of vaginal health in terms of increase of lactobacillar flora and reduction of vaginal pH in place of women treated with EV+NOMAC that showed a reduction of cervical mucus. Finally, our data about the effects on vaginal flora exerted by two estroprogestin pills (EPs) containing a natural estrogen suggest slight, but interesting differences in terms of vaginal ecology. These differences could be related to the type of estrogen, type of progestin, regimen of administration and, after all, to the net balance between estrogenic and progestin component of the EPs.

    Elucidating the factors that impinge on the stability of bacterial communities in the vagina may help in predicting the risk of diseases that affect womens health. Here, we describe the temporal dynamics of the composition of vaginal bacterial communities in 32 reproductive age women over a 16-week period. The analysis revealed the dynamics of five major classes of bacterial communities and showed that some communities change markedly over short time periods, whereas others are relatively stable. Modeling community stability using new quantitative measures indicates that deviation from stability correlates with time in the menstrual cycle, bacterial community composition and sexual activity. The women studied are healthy, thus it appears that neither variation in community composition per se, nor higher levels of observed diversity (co-dominance) are necessarily indicative of dysbiosis, in which there is microbial imbalance accompanied by symptoms.

    Background. A transverse vaginal septum (TVS) is a rare obstructing anomaly, caused due to improper fusion of Mllerian ducts and urogenital sinus during embryogenesis. Case. A 15-year-old girl presented with primary amenorrhea. She had multiple congenital anomalies. Initial examination and imaging investigation revealed the presence of a unicornuate uterus and a TVS. The TVS was excised; however the patient was unable to perform vaginal dilation postoperatively leading to recurrent stricture formation. She underwent multiple surgeries for excision of the stricture. The patient was eventually evaluated every day in the clinic until she was able to demonstrate successful vaginal dilatation in the presence of a clinician. Summary and Conclusion. Properly guided regular and intensive vaginal dilation after TVS excision may decrease the need of reoperations due to recurrent stricture formation. PMID:26078895

    2014-01-01

    Background. Uterine inversion is a rare, but life threatening, obstetrical emergency which occurs when the uterine fundus collapses into the endometrial cavity. Various conservative and surgical therapies have been outlined in the literature for the management of uterine inversions. Case. We present a case of a chronic, recurrent uterine inversion, which was diagnosed following spontaneous vaginal delivery and recurred seven weeks later. The uterine inversion was likely due to a leiomyoma. This late-presenting, chronic, recurring uterine inversion was treated with a vaginal hysterectomy. Conclusion. Uterine inversions can occur in both acute and chronic phases. Persistent vaginal bleeding with the appearance of a prolapsing fibroid should prompt further investigation for uterine inversion and may require surgical therapy. A vaginal hysterectomy may be an appropriate management option in select populations and may be considered in women who do not desire to maintain reproductive function. PMID:25379314

    From 1984 to 1988, we corrected and prevented the prolapse of the vaginal vault of patients who wanted to maintain a satisfactory sexual function. This was done by adopting two different surgical techniques. The first, generally favored technique, was performed upon 179 patients and consisted of a colposuspension to the sacrospinous ligaments. The second technique, a colposacropexis, was performed upon 71 patients, in which abdominal associated pathologic changes required an abdominal surgical approach. Colposacropexis was performed, whenever possible, directly to the anterior longitudinal vertebral ligament or using synthetic materials (Mersilene [polyester fiber], Teflon [polytetrafluoroethylene] and Gore-Tex [expanded, reinforced polytetrafluoroethylene]). Both colposacropexis and vaginal suspension to sacrospinous ligaments have had comparable results in vaginal accommodation and long term fixation. Vaginal approach has a lower incidence of operative complications than the abdominal approach and seems to ensure a lower risk of recurrent cystocele, even if simple and asymptomatic. PMID:1514157

    The vaginal delivery of various drugs is well described and its relevance established in current medical practice. Alongside recent advances and achievements in the fields of pharmaceutical nanotechnology and nanomedicine, there is an increasing interest in the potential use of different nanocarriers for the delivery of old and new pharmacologically active molecules with either therapeutic or prophylactic purposes. Nanosystems of polymeric nature in particular have been investigated over the last years and their interactions with mucosal fluids and tissues, as well as genital tract biodistribution upon vaginal administration, are now better understood. While different applications have been envisioned, most of the current research is focusing in the development of nano-formulations with the potential to inhibit the vaginal transmission of HIV upon sexual intercourse. The present work focuses its discussion on the potential and perils of polymer-based nanocarriers for the vaginal administration of different pharmacologically active molecules. PMID:25550217

    Endometrial carcinoma is the most common malignancy arising in the female genital tract. Intracavitary vaginal cuff irradiation may be given alone or with external beam irradiation in patients determined to be at risk for locoregional recurrence. Vaginal cylinders are often used to deliver a brachytherapy dose to the vaginal apex and upper vagina or the entire vaginal surface in the management of postoperative endometrial cancer or cervical cancer. The dose distributions of HDR vaginal cylinders must be evaluated carefully, so that clinical experiences with LDR techniques can be used in guiding optimal use of HDR techniques. The aim of this study was to optimize dose distribution for Gammamed plus vaginal cylinders. Placement of dose optimization points was evaluated for its effect on optimized dose distributions. Two different dose optimization point models were used in this study, namely non-apex (dose optimization points only on periphery of cylinder) and apex (dose optimization points on periphery and along the curvature including the apex points). Thirteen dwell positions were used for the HDR dosimetry to obtain a 6-cm active length. Thus 13 optimization points were available at the periphery of the cylinder. The coordinates of the points along the curvature depended on the cylinder diameters and were chosen for each cylinder so that four points were distributed evenly in the curvature portion of the cylinder. Diameter of vaginal cylinders varied from 2.0 to 4.0 cm. Iterative optimization routine was utilized for all optimizations. The effects of various optimization routines (iterative, geometric, equal times) was studied for the 3.0-cm diameter vaginal cylinder. The effect of source travel step size on the optimized dose distributions for vaginal cylinders was also evaluated. All optimizations in this study were carried for dose of 6 Gy at dose optimization points. For both non-apex and apex models of vaginal cylinders, doses for apex point and three dome points were higher for the apex model compared with the non-apex model. Mean doses to the optimization points for both the cylinder models and all the cylinder diameters were 6 Gy, matching with the prescription dose of 6 Gy. Iterative optimization routine resulted in the highest dose to apex point and dome points. The mean dose for optimization point was 6.01 Gy for iterative optimization and was much higher than 5.74 Gy for geometric and equal times routines. Step size of 1 cm gave the highest dose to the apex point. This step size was superior in terms of mean dose to optimization points. Selection of dose optimization points for the derivation of optimized dose distributions for vaginal cylinders affects the dose distributions.

    Recurrent vulvovaginal candidiasis, caused by Candida albicans, is a significant problem in women of childbearing age. Although cell-mediated immunity (CMI) due to T cells and cytokines is the predominant host defense mechanism against C. albicans at mucosal tissue sites, host defense mechanisms against C. albicans at the vaginal mucosa are poorly understood. Based on an estrogen-dependent murine model of vaginal candidiasis, our data suggest that systemic CMI is ineffective against C. albicans vaginal infections. Thus, we have postulated that local immune mechanisms are critical for protection against infection. In the present study, the kinetic production of chemokines normally associated with the chemotaxis of T cells, macrophages (RANTES, MIP-1α, MCP-1), and polymorphonuclear neutrophils (MIP-2) was examined following intravaginal inoculation of C. albicans in estrogen-treated or untreated mice. Results showed significant increases in MCP-1 protein and mRNA in vaginal tissue of infected mice as early as 2 and 4 days postinoculation, respectively, that continued through a 21-day observation period, irrespective of estrogen status. No significant changes were observed with RANTES, MIP-1α, or MIP-2, although relatively high constitutive levels of RANTES mRNA and MIP-2 protein were observed. Furthermore, intravaginal immunoneutralization of MCP-1 with anti-MCP-1 antibodies resulted in a significant increase in vaginal fungal burden early during infection, suggesting that MCP-1 plays some role in reducing the fungal burden during vaginal infection. However, the lack of changes in leukocyte profiles in vaginal lavage fluids collected from infected versus uninfected mice suggests that MCP-1 functions to control vaginal C. albicans titers in a manner independent of cellular chemotactic activity.

    Communication failures are the most common root causes of perinatal deaths and injuries. We designed and tested a Vaginal Delivery Safety Checklist to improve communication and assist delivery teams' risk assessments and plans for potential complications of vaginal birth. Delivery teams found the checklist easy, convenient, and helpful. Teams completed the checklist within 2 to 3 minutes and showed improved teamwork, communication, and decision making. PMID:26851050

    Apart from the documentation of the spermicidal effects of KY Jelly and Surgilube, little information about the effect of vaginal lubricants on sperm motility has been available. Fifteen substances utilizable as vaginal lubricants were therefore tested for their effect on sperm motility in vitro. Petroleum jelly and glycerin had minimal detrimental effects on motility and apparently are the lubricants of choice when an infertility problem exists. PMID:1237417

    Objective To explore the efficacy of local oxytocin for the treatment of post-menopausal vaginal atrophy. Design Double-blinded randomised controlled trial. Setting Healthy post-menopausal women in Stockholm, Sweden. Participants Sixty four post-menopausal women between February and June 2012 at the Karolinska University Hospital Huddinge/Sweden. Main outcome measures The efficacy of oxytocin for treatment of vaginal atrophy after seven weeks and cytological evaluation. Results The percentage of superficial cells in the vaginal smears and the maturation values were significantly increased after seven weeks of treatment with vagitocin 400 IU (p?=?0.0288 and p?=?0.0002, respectively). The vaginal pH decreased significantly after seven weeks of treatment with vagitocin 100 IU (p?=?0.02). The scores of vaginal atrophy, according to the histological evaluation, were significantly reduced after administration of vagitocin 100 IU (p?=?0.03). The thickness of the endometrium did not differ between the treatment and placebo groups after seven weeks of treatment. The symptom experienced as the most bothersome was significantly reduced after seven weeks of treatment in the women receiving vagitocin 400 IU compared to women in the placebo group (p?=?0.0089). Conclusions Treatment with intravaginally applied oxytocin could be an alternative to local estrogen treatment in women with post-menopausal vaginal atrophy. PMID:25995333

    Different non-ionic cellulose ethers (methyl cellulose, MC; hydroxyethyl cellulose, HEC; hydroxypropyl cellulose, HPC; hydroxypropylmethyl cellulose, HPMC) and microcrystalline cellulose (MCC) were investigated as matrix formers for preparation of mini-tablets targeting vaginal drug delivery. Hexyl aminolevulinat hydrochloridum (HAL) was used as a model drug. The mini-tablets were characterized with respect to their mechanical strength, bioadhesion towards cow vaginal tissue in two independent tests (rotating cylinder test, detachment test using texture analyzer), and dissolution rate in two media mimicking the pH levels of fertile, healthy and post-menopausal women (vaginal fluid simulant pH 4.5, phosphate buffer pH 6.8). Mini-tablets with a matrix of either HPMC or HPC were found to possess adequate mechanical strength, superior bioadhesive behavior towards vaginal tissue, and pH independent controlled release of the model drug, suggesting that both systems would be suited for the treatment of women regardless of age, i.e., respective of their vaginal pH levels. Bioadhesive mini-tablets offer a potential for improved residence time in the vaginal cavity targeting contact with mucosal tissue and prolonged release of the drug. PMID:25166286

    Background Vaginal symptoms are a common chief complaint amongst women visiting outpatient clinics in rural Haiti. Methods A systematic sample of 206 consecutive females over age 18 with gynecological symptoms underwent gynecologic examination and laboratory testing for chlamydia, gonorrhea, syphilis, HIV infection, trichomoniasis, candidiasis, and bacterial vaginosis. Results Among 206 women, 174 (84%) presented with vaginal discharge, 165 (80%) with vaginal itching, 123 (60%) with vaginal pain or dysuria, and 18 (9%) with non-traumatic vaginal sores or boils. Laboratory results were positive for Chlamydia trachomatis in 5.4% (11/203), syphilis in 3.5% (7/202), HIV in 1.0% (2/200), and Neisseria gonorrhoeae in 1.0% (2/203). Among those that had microscopy, hyphae suggestive of candidiasis were visualized in 2.2% (1/45) and no cases of trichomoniasis were diagnosed 0% (0/45). Bacterial vaginosis was diagnosed in 28.3% (13/46). The prevalence of chlamydia was 4.9 (95% CI: 1.3-17.7) times greater among those 25 years of age and under (10.8%) than those older (2.3%). Conclusions Chlamydia and bacterial vaginosis were the most common sexually transmitted infection and vaginal condition, respectively, in this study of rural Haitian adult women. The higher risk of chlamydia in younger women suggests education and screening programs in young women should be considered. PMID:24352116

    Objective. To determine if sexual intercourse reduces absorption of vaginal progesterone gel in women and to determine if progesterone is absorbed by the male during intercourse. Study Design. Prospective, randomized, cross over, controlled study of 20 reproductive-aged women and their male sexual partners randomized to receive vaginal progesterone gel (Crinone 8% gel, Actavis Inc., USA) or placebo cream. Serum progesterone for both male and female partners were measured 10 hours after intercourse. One week later, subjects were crossed over to receive the opposite formulation. In the third week, women used progesterone gel at night and abstained from intercourse. Results. Serum progesterone was significantly reduced with vaginal progesterone gel + intercourse compared with vaginal progesterone gel + abstinence (P = 0.0075). Men absorbed significant progesterone during intercourse with a female partner using vaginal progesterone gel compared to placebo (P = 0.0008). Conclusion(s). Vaginal progesterone gel is reduced in women after intercourse which may decrease drug efficacy during luteal phase support. Because men absorb low levels of progesterone during intercourse, exposure could cause adverse effects such as decreased libido. This study is registered under Clinical Trial number NCT01959464.

    Background and Objectives: Our aim was to evaluate whether the use of barbed suture for vaginal cuff closure is associated with a decrease in postoperative vaginal bleeding compared with cuff closure with polyglactin 910 in patients who have undergone laparoscopic hysterectomy. Methods: We performed a cohort study of patients who underwent laparoscopic hysterectomy between January 2008 and July 2012 by the minimally invasive gynecologic surgery division of the Gynecology, Obstetrics and Human Reproduction Department at Fundacin Santa Fe de Bogot University Hospital, Bogot, Colombia. Results: A total of 232 women were studied: 163 were in the polyglactin 910 group, and 69 were in the barbed suture group. The main outcome, postoperative vaginal bleeding, was documented in 53 cases (32.5%) in the polyglactin 910 group and in 13 cases (18.8%) in the barbed suture group (relative risk, 0.57; 95% confidence interval, 0.340.9; P = .03). No statistically significant differences were found in other postoperative outcomes, such as emergency department admission, vaginal cuff dehiscence, infectious complications, and the presence of granulation tissue. Conclusion: In this study an inverse association was observed between the use of barbed suture for vaginal cuff closure during laparoscopic hysterectomy and the presence of postoperative vaginal bleeding.

    The incidence of fungal infections is growing in the last 20 years. The epidemiological studies show that 45% of all vaginal infections are caused by Candida albicans or other Candida species. 7 out of 10 women suffer from yeast infection at least once in a lifetime and 4 out of 10 have multiple recurrences. 20-55% of women have asyptomatic vaginal colonization with Candida species. It is strongly believed that fungal infection is not sexually transmitted disease. The route of transmission is oral and it is estrogene dependant. The diagnosis is based on macroscopic, microscopic examination (KOH preparation), culture and rarely Pap test. Treatment of vaginal candidiosis is based on two principles: elimination of predisposing factors antifungal treatment Local treatment is the first line of choice in cases of acute vaginal yeast infection with 84-90% success rate. There are a variety of local preparations on our market including Nizoral, Clotrimazole, Canesten, Gyno-Daktarine, Gyno-Pevaryl, Miconazole. Different groups of broad spectrum oral antimycotics are also used including Nystatine, Ketoconazole (Nizoral), Fluconazole (Diflucan, Fungolon, Mycosyst), itraconazole (Orungal). The treatment of chronic, recurrent and resistant forms of vaginal candidosis is carried out with prolonged local and/or systemic therapy for a period of at least 6 months. Different regimes of therapy are proposed. Fluconazole is an oral drug of choice for continuous treatment of vaginal yeast infection with the least toxicity. PMID:14619753

    Nonspecific vaginitis (NSV), also named bacterial vaginosis, is one of the most common genital system diseases in women during their reproductive years. The specific pathogenic mechanism of NSV is not clear yet. Upon the balance alteration, large amount of reactive oxidant species (ROS) is generated and accumulated in the genital tract, and thus resulting in oxidative stress, which has been reported to be an important trigger of mitochondrial pathway cell apoptosis. In this study, the antioxidant secretion level and antioxidant enzyme activity in the vaginal discharge were evaluated to analyze the oxidative status in the vaginal tract of NSV patients. The effect of oxidative stress on the vaginal mucosa epithelial cell apoptosis was then studied. The role of oxidative stress on NSV development was uncovered; thus open new direction for the prevention and treatment of NSV by providing antiradical agents was revealed. PMID:26558281

    Objective of the present study was to develop and evaluate vaginal films with essential in vitro studies. Films were developed using hydroxypropyl methylcellulose as a polymer and formulations were coded. The developed films were evaluated with Fourier transform infrared spectroscopy, drug content, viscosity, surface pH, thickness, mechanical characterisation and in vitro drug release study. Fourier transform infrared spectroscopy results confirmed that there is no chemical interaction between drug and stabilisers/excipients. The batch variation was not more than 5% for average thickness and weight of the films. The drug content for the prepared formulation was in the range of 72.320.18% to 94.480.54%. Viscosity of the formulations increased with the increase in concentration of polymer. Mechanical characterisation revealed that tensile strength and percentage elongation of the films improved as there is increase in degree of substitution of the polymer, but the values of modulus decreased which confirmed that all the prepared films are soft in nature. The in vitro study indicated that 1 and 2% concentrations of polymer are the least concentrations to control the release of drug whereas the 4% concentration of polymer is a good and more effective concentration to control the release. Only one prepared formulation released the drug by following anomalous transport whereas other film formulations released the fluconazole by following Fickian diffusion mechanism. Prepared vaginal films may be an important alternative for the treatment of vaginal candidiasis, because these prepared films suggest the benefits of controlled release of fluconazole at the site of absorption.

    The vaginal microbiome is an emerging concern in prenatal health. Because the sampling process of vaginal microbiota may pose potential risks for pregnant women, the choice of sampling site should be carefully considered. However, whether the microbial diversity is different across various sampling sites has been controversial. In the present study, three repeated swabs were collected at the cervix (C), posterior fornix (P), and vaginal canal (V) from 34 Chinese women during different pregnancy stages, and vaginal species were determined using the Illumina sequencing of 16S rRNA tag sequences. The identified microbiomes were classified into four community state types (CSTs): CST I (dominated by L. crispatus), CST II (dominated by L. gasseri), CST III (dominated by L. iners), and CST IV-A (characterized by a low abundance of Lactobacillus, but with proportions of various species previously shown to be associated with bacterial vaginosis). All individuals had consistent CST at the three sampling sites regardless of pregnancy stage and CST group. In addition, there was little heterogeneity across community structures within each individual, as determined by LEfSe, indicating high vaginal microbiome homogeneity at the three sampling sites. The present study also revealed different beta diversity during pregnancy stages. The vaginal microbiome variation among women during trimester T1 (9??2.6 weeks) is larger than that of non-pregnant women and women from other trimesters, as demonstrated by the UniFrac distance (P?vaginal microbiome of postpartum women compare to women in gestation. These results will be useful for future studies of the vaginal microbiota during pregnancy. PMID:25230887

    The purpose of this investigation was to evaluate the impact of the vaginal milieu on the presence of abnormal Pap smears and a positive human papilloma virus (HPV) test. A cross-sectional study was conducted between June 2014 and May 2015, evaluating the vaginal discharge by fresh wet mount microscopy and comparing these data with Pap smear findings. Wet mount slides were scored for bacterial vaginosis (BV), aerobic vaginitis (AV), presence of Candida and Trichomonas vaginalis. Cytologic evaluation was done on all Pap smears according to the Bethesda criteria. The cobas© HPV Test (Roche) was performed for HPV detection. A total of 622 cases were evaluated. The mean age of the patients was 41.6 ± 10.65 years (range 21-75). Eighty-three women (13.3 %) had a cytology result worse than low-grade squamous intraepithelial lesion (LSIL). When comparing this group with the one with normal or minor [atypical squamous cells of undetermined significance (ASC-US) or LSIL] Pap smear abnormalities, there were no differences in the presence of Candida (32.5 % vs. 33.2 %, p = 1.0), absence of lactobacilli (38.6 % vs. 32.5 %, p = 0.32) or BV (20.5 % vs. 13.2 %, p = 0.09). On the other hand, moderate or severe inflammation (msI) (41.0 % vs. 28.8 %, p = 0,04), moderate or severe AV (msAV) (16.9 % vs. 7.2 %, p = 0.009) and msAV/BV (37.3 % vs. 20.0 %, p = 0.001) were more common in women with such major cervical abnormalities. No significant association was found between deviations of the vaginal milieu and high-risk HPV infection. The presence of msI or msAV, but not BV, is independently associated with an increased risk of major cervical cytological abnormalities, but not with HPV infection. PMID:26810061

    Bacterial vaginosis (BV) is a common vaginal disorder characterized by an alteration of the vaginal bacterial morphotypes, associated with sexually transmitted infections and adverse pregnancy outcomes. The purpose of the present study was to evaluate the impact of different doses of rifaximin vaginal tablets (100 mg/day for 5 days, 25 mg/day for 5 days, and 100 mg/day for 2 days) on the vaginal microbiota of 102 European patients with BV enrolled in a multicenter, double-blind, randomized, placebo-controlled study. An integrated molecular approach based on quantitative PCR (qPCR) and PCR-denaturing gradient gel electrophoresis (PCR-DGGE) was used to investigate the effects of vaginal tablets containing the antibiotic. An increase in members of the genus Lactobacillus and a decrease in the BV-related bacterial groups after the antibiotic treatment were demonstrated by qPCR. PCR-DGGE profiles confirmed the capability of rifaximin to modulate the composition of the vaginal microbial communities and to reduce their complexity. This molecular analysis supported the clinical observation that rifaximin at 25 mg/day for 5 days represents an effective treatment to be used in future pivotal studies for the treatment of BV.

    Introduction: Menopause is suspected with age, cessation of menstruation for more than a year and presence of symptoms. The diagnosis of menopause is confirmed by follicle stimulating hormone (FSH) levels >40 IU/L. Few studies have focused on vaginal pH for menopausal diagnosis. It is a simple, non-invasive and inexpensive method for this purpose. Aim of the Study: The following study is to correlate the serum follicle stimulating hormone (FSH) level with vaginal pH estimation in menopause. Materials and Methods: This is a cross-sectional descriptive study conducted in 173 women aged 31-60 years with menopausal symptoms who attended the Menopausal Clinic of our hospital from January 2012 to January 2013. Vaginal pH was measured using pH micro-meter strips and serum FSH levels were measured using immunoassay methods. The data obtained was then analyzed using Statistical Package for the Social Sciences software (version 17) and results were evaluated statistically by the Chi-square and Kappa tests. P ? 0.05 was considered to be statistically significant. Results: According to our study of the 173 women studied, mean FSH level was 46.5 IU/L and mean vaginal pH was 5.3. If the menopausal hallmark is considered to be vaginal pH >4.5 and serum FSH ?40 IU/L, the sensitivity of vaginal pH for menopausal diagnosis was 84.9% and of serum FSH is 77.4%, respectively. Conclusion: Vaginal pH is a simple, accurate and cost-effective tool that can be suggested as a suitable and better alternative to serum FSH estimation for the diagnosis of menopause. PMID:24672204

    Vaginal reconstruction was performed in 14 patients who had developed vaginal stenosis secondary to extensive pelvic fibrosis after pelvic radiation therapy (12 patients) or prior vaginal reconstruction (2 patients). Sixteen procedures were performed using a split-thickness skin graft. All patients had satisfactory vaginal restoration, and 12 patients reported good vaginal function. No fistula developed as a result of the operative procedure, but one patient later developed a rectovaginal fistula resulting from tumor recurrence. Successful vaginal reconstruction can be achieved even years after initial therapy in patients who develop an obliterated vagina from previous radiation or surgery.

    Bacterial vaginosis (BV) is one of most prevalent complications among reproductive-aged women. Metromidazole prescription, which is considered as the first-line treatment of BV, is usually followed by a few side effects. Besides, there is a growing tendency toward herbal medicines for the treatment of vaginitis. Antibacterial and antifungal effects of Zataria multiflora (Z. multiflora) have been demonstrated in vitro and in vivo. This study aimed to compare the therapeutic effects of the Z. multiflora vaginal cream and metronidazole vaginal gel on bacterial vaginosis. This was a randomized clinical trial on 90 married women aged 18-40 affected by BV who attended for treatment to the gynecology clinic of Shabih-Khani Hospital. They randomly divided to two groups of 45 participants. Diagnostic criteria were Amsel's criteria and Gram stain. Z. multiflora vaginal cream or metronidazole vaginal gel for five-night usage were prescribed to each group, and after 2-7 days therapeutic effects on participants' complications and their Amsel criteria were assessed. Data analysis was performed by McNemar and Fisher exact tests. Patients' complication and their Amsel's criteria were significantly decreased after treatment with Z. multiflora or metronidazole (p<0.05). Relative risk for unresponsiveness to treatment with Z. multiflora, to unresponsiveness to metronidazole was 1.5, which was not significant. Therapeutic effects of Z. multiflora vaginal cream are similar to metronidazole vaginal gel on BV. Therefore it could be an appropriate choice to BV treatment for those interested in herbal medicines or those affected by side effects of metronidazole. PMID:18824338

    The vagina is a most neglected organ. It is usually clinically considered with a minimalistic view, as a 'connecting tube' for a number of physiologic functions: passage of menstrual blood, intercourse, natural conception and delivery. Unmet needs include, but are not limited to, respect of vaginal physiologic biofilms; diagnosis and care of the optimal tone of the levator ani, which surrounds and partly support it; care of its anatomic integrity at and after delivery and at pelvic/vaginal surgery; care of long-term consequences of pelvic radiotherapy; long-term care of the atrophic changes it will undergo after the menopause, unless appropriate, at least local, estrogen therapy is used; appreciation and respect of its erotic meaning, as a loving, receptive, 'bonding' organ for the couple. The vaginal erotic value is key as a non-visible powerful center of femininity and sexuality, deeply and secretly attractive in terms of taste, scent (together with the vulva), touch and proprioception. The most welcoming when lubrication, softness and vaginal orgasm award the woman and the partner with the best of pleasures. Prevention of sexual/vaginal abuse is a very neglected unmet need, as well. Who cares? PMID:26366794

    In a prospective clinical study we investigated 115 patients prior to vaginal surgical interventions to determine the antimicrobial efficacy of six different procedures for vaginal antisepsis. To sample the microorganisms we used a cotton swab moistened with a neutralising fluid. Immediately after the time of action of the antiseptic procedures (3 minutes), providone-iodine solution, applied undiluted or diluted 1:10, yielded the strongest median reduction of the vaginal flora (log RF 3.60 and 2.68, respectively). Of three detergents with antiseptic efficacy, octenidine 0.1% was the most efficient formula (log RF 2.32). After 30 minutes the log reduction factors (log RF) of almost all procedures (log RF 2.79-3.25) were in a fairly close range, excepting chlorohexidine 0.05% (log RF 2.07). Overall, the antiseptic detergents showed a marked residual effect, which was less pronounced, if at all, with providone-iodine solutions. A germ-reducing effect of povidone-iodine vaginal suppositories, applied 2 to 3 hrs prior to surgery, was not confirmed, while additional findings indicated that providone-iodine solution applied with the help of a vaginal douche yields a similarly strong germ reduction as the application by means of a ball swabs.

    The concurrent increases in global population and sexually transmitted infection (STI) demand a search for agents with dual spermicidal and microbicidal properties for topical vaginal application. Previous attempts to develop the surfactant spermicide, nonoxynol-9 (N-9), into a vaginal microbicide were unsuccessful largely due to its inefficiency to kill microbes. Furthermore, N-9 causes damage to the vaginal epithelium, thus accelerating microbes to enter the women's body. For this reason, antimicrobial peptides (AMPs), naturally secreted by all forms of life as part of innate immunity, deserve evaluation for their potential spermicidal effects. To date, twelve spermicidal AMPs have been described including LL-37, magainin 2 and nisin A. Human cathelicidin LL-37 is the most promising spermicidal AMP to be further developed for vaginal use for the following reasons. First, it is a human AMP naturally produced in the vagina after intercourse. Second, LL-37 exerts microbicidal effects to numerous microbes including those that cause STI. Third, its cytotoxicity is selective to sperm and not to the female reproductive tract. Furthermore, the spermicidal effects of LL-37 have been demonstrated in vivo in mice. Therefore, the availability of LL-37 as a vaginal spermicide/microbicide will empower women for self-protection against unwanted pregnancies and STI. PMID:26978373

    OBJECTIVES To synthesize the published literature on vaginal birth after cesarean (VBAC). Specifically, to review the trends and incidence of VBAC, maternal benefits and harms, infant benefits and harms, relevant factors influencing each, and the directions for future research. DATA SOURCES Relevant studies were identified from multiple searches of MEDLINE; DARE; the Cochrane databases (1966 to September 2009); and from recent systematic reviews, reference lists, reviews, editorials, Web sites, and experts. REVIEW METHODS Specific inclusion and exclusion criteria were developed to determine study eligibility. The target population includes healthy women of reproductive age, with a singleton gestation, in the U.S. with a prior cesarean who are eligible for a trial of labor (TOL) or elective repeat cesarean delivery (ERCD). All eligible studies were quality rated and data were extracted from good or fair quality studies, entered into tables, summarized descriptively and, when appropriate, pooled for analysis. The primary focus of the report was term pregnancies. However, due to a small number of studies on term pregnancies, general population studies including all gestational ages (GA) were included in appropriate areas. RESULTS We identified 3,134 citations and reviewed 963 papers for inclusion, of which 203 papers met inclusion and were quality rated. Studies of maternal and infant outcomes reported data based upon actual rather than intended router of delivery. The range for TOL and VBAC rates was large (28-82 percent and 49-87 percent, respectively) with the highest rates being reported in studies outside of the U.S. Predictors of women having a TOL were having a prior vaginal delivery and settings of higher-level care (e.g., tertiary care centers). TOL rates in U.S. studies declined in studies initiated after 1996 from 63 to 47 percent, but the VBAC rate remained unimproved. Hispanic and African American women were less likely than their white counterparts to have a vaginal delivery. Overall rates of maternal harms were low for both TOL and ERCD. While rare for both TOL and ERCD, maternal mortality was significantly increased for ERCD at 13.4 per 100,000 versus 3.8 per 100,000 for TOL. The rates of maternal hysterectomy, hemorrhage, and transfusions did not differ significantly between TOL and ERCD. The rate of uterine rupture for all women with prior cesarean is 3 per 1,000 and the risk was significantly increased with TOL (4.7/1,000 versus 0.3/1,000 ERCD). Six percent of uterine ruptures were associated with perinatal death. No models have been able to accurately predict women who are more likely to deliver by VBAC or to rupture. Women with one prior cesarean delivery and previa had a statistically significant increased risk of adverse events compared with previa patients without a prior cesarean delivery; blood transfusion (15 versus 32.2 percent), hysterectomy (0.7 to 4 percent versus 10 percent), and composite maternal morbidity (15 versus 23-30 percent). Perinatal mortality was significantly increased for TOL at 1.3 per 1,000 versus 0.5 per 1,000 for ERCD. Insufficient data were found on nonmedical factors such as medical liability, economics, hospital staffing, structure and setting, which all appear to be important drivers for VBAC. CONCLUSIONS Each year 1.5 million childbearing women have cesarean deliveries, and this population continues to increase. This report adds stronger evidence that VBAC is a reasonable and safe choice for the majority of women with prior cesarean. Moreover, there is emerging evidence of serious harms relating to multiple cesareans. Relatively unexamined contextual factors such as medical liability, economics, hospital structure, and staffing may need to be addressed to prioritize VBAC services. There is still no evidence to inform patients, clinicians, or policymakers about the outcomes of intended route of delivery because the evidence is based largely on the actual route of delivery. This inception cohort is the equivalent of intention to treat for randomized controlled trials and this gap in information is critical. A list of future research considerations as prioritized by national experts is also highlighted in this report. PMID:20629481

    2005-01-01

    Objective: This study compares the operative parameters of laparoscopic supracervical hysterectomy, laparoscopically assisted vaginal hysterectomy, total vaginal hysterectomy, and total abdominal hysterectomy in patients in a small suburban medical center. Methods: This investigation is a Canadian Classification II-2. It was performed in a 238 bed not-for-profit community general hospital. Charts of 117 patients were reviewed. These patients had undergone the following procedures: laparoscopic supracervical hysterectomy, laparoscopically assisted vaginal hysterectomy, total vaginal hysterectomy, total abdominal hysterectomy; questionnaires completed by the patients were reviewed. All patients had hysterectomies performed by members of the Ob/Gyn department of Alamance Regional Medical Center. Comparisons of intraoperative and postoperative events were made in those patients who consented to the study and who returned their questionnaires. Parameters compared were patient age, weight, preoperative diagnosis, operative time, operative complications, blood loss, uterine weight, length of stay, postoperative complications, return to hospital, return to work, resumption of intercourse, dyspareunia, and bowel or bladder problems. Results: Patient demographics and outcomes are similar. Laparoscopic supracervical hysterectomy showed lower morbidity and quicker return to normal function, but most findings did not reach statistical significance. Conclusion: The results support the conclusion that the patients in each arm of the study are similar. The operative parameters show a longer operating time for the laparoscopic procedures than for total abdominal hysterectomy and total vaginal hysterectomy, respectively. The other indicators of morbidity show slight advantages of laparoscopic supracervical hysterectomy in blood loss, length of stay, and resumption of normal activities. PMID:16121874

    An 8-year-old girl was taken to an outpatient clinic of surgery suffering from rectorrhagia and purulent, smelly vaginal discharge. Colonoscopy and biopsy were done before referring and sulfasalazine regime was administrated for probable colitis. The surgeon performed a rigid rectosigmoidoscopy under general anesthesia and no positive evidence was found. Having examined the hymen, it was found to be intact but a purulent discharge was observed. After drying the discharge, a black foreign body was seen in the bottom of the vagina and brought out by a fine forceps. It was a toy's wheel. The patient and her mother both denied foreign body abusing history. It was recommended she go for a psychological consultation. Generally speaking, all young patients suffering from vaginal or rectal bleeding with or without discharge should have their vagina checked for a foreign body. What is recommended in such cases is to undergo sonography or plain radiography before considering invasive or non-invasive procedures for evaluating anal and sigmoid abnormalities. Last but not least, a vaginal irrigation, precise examination of hymen, and posterior fossa can prove very useful for detecting simple vaginal bodies that can lead to various vaginal, rectal and abdominal complications.

  13. The Human Vaginal Bacterial Biota and Bacterial Vaginosis

    The bacterial biota of the human vagina can have a profound impact on the health of women and their neonates. Changes in the vaginal microbiota have been associated with several adverse health outcomes including premature birth, pelvic inflammatory disease, and acquisition of HIV infection. Cultivation-independent molecular methods have provided new insights regarding bacterial diversity in this important niche, particularly in women with the common condition bacterial vaginosis (BV). PCR methods have shown that women with BV have complex communities of vaginal bacteria that include many fastidious species, particularly from the phyla Bacteroidetes and Actinobacteria. Healthy women are mostly colonized with lactobacilli such as Lactobacillus crispatus, Lactobacillus jensenii, and Lactobacillus iners, though a variety of other bacteria may be present. The microbiology of BV is heterogeneous. The presence of Gardnerella vaginalis and Atopobium vaginae coating the vaginal epithelium in some subjects with BV suggests that biofilms may contribute to this condition. PMID:19282975

    A previous history of breast cancer can induce problems in some women, which may necessitate hysterectomy as well as oophorectomy. This study included 20 women with a history of breast cancer with endometrial hyperplasia and recurrent vaginal bleeding or the need for oophorectomy because of metastatic breast cancer along with concomitant hysterectomy. The aim of this study is to show that benign indications for hysterectomy with oophorectomy, arising out of management of breast cancer in the past, can be dealt with by the least invasive approach via the vaginal route, provided vaginal hysterectomy is not contraindicated and the abdomino-pelvic area is free of metastasis. All 20 women had an uneventful postoperative period with rapid recovery, economic benefit and short hospital stay. PMID:21823858

    The minimally invasive approach for hysterectomy with proven benefits and lower morbidity has become the gold standard, even in women with large uterine masses. Most women with a malignant condition present with abnormal vaginal bleeding and/or suspicious imaging such that few are diagnosed by final histopathology after surgery. However, if a malignancy is not diagnosed preoperatively, intraabdominal morcellation for uterus extraction has an increased risk for potential tumor spread and peritoneal metastases, especially in cases of unexpected leiomyosarcoma. We describe a simple method to wrap the uterus in a contained environment with a plastic bag through the posterior vaginal fornix prior to conventional coring morcellation for vaginal extraction in total laparoscopic hysterectomy. We further describe our experience with a risk stratification and treatment algorithm to implement this procedure in daily routine. A video and an illustrating sketch demonstrate the simplicity and safety of the procedure. PMID:25460836

    Understanding of microbial communities inhabiting cattle vaginal tract may lead to a better comprehension of bovine physiology and reproductive health being of great economic interest. Up to date, studies involving cattle microbiota are focused on the gastrointestinal tract, and little is known about the vaginal microbiota. This study aimed to investigate the vaginal microbiome in Nellore cattle, heifers and cows, pregnant and non-pregnant, using a culture independent approach. The main bacterial phyla found were Firmicutes (~40–50%), Bacteroidetes (~15–25%) and Proteobacteria (~5–25%), in addition to ~10–20% of non-classified bacteria. 45–55% of the samples were represented by only ten OTUs: Aeribacillus, Bacteroides, Clostridium, Ruminococcus, Rikenella, Alistipes, Bacillus, Eubacterium, Prevotella and non-classified bacteria. Interestingly, microbiota from all 20 animals could be grouped according to the respiratory metabolism of the main OTUs found, creating three groups of vaginal microbiota in cattle. Archaeal samples were dominated by the Methanobrevibacter genus (Euryarchaeota, ~55–70%). Ascomycota was the main fungal phylum (~80–95%) and Mycosphaerella the most abundant genus (~70–85%). Hormonal influence was not clear, but a tendency for the reduction of bacterial and increase of archaeal populations in pregnant animals was observed. Eukaryotes did not vary significantly between pregnant and non-pregnant animals, but tended to be more abundant on cows than on heifers. The present work describes a great microbial variability in the vaginal community among the evaluated animals and groups (heifers and cows, pregnant and non-pregnant), which is significantly different from the findings previously reported using culture dependent methods, pointing out the need for further studies on this issue. The microbiome found also indicates that the vaginal colonization appears to be influenced by the gastrointestinal community. PMID:26599789

    Streptococcus agalactiae (group B streptococcus [GBS]) colonizes the rectovaginal tract in 20% to 30% of women and during pregnancy can be transmitted to the newborn, causing severe invasive disease. Current routine screening and antibiotic prophylaxis have fallen short of complete prevention of GBS transmission, and GBS remains a leading cause of neonatal infection. We have investigated the ability of Streptococcus salivarius, a predominant member of the native human oral microbiota, to control GBS colonization. Comparison of the antibacterial activities of multiple S. salivarius strains by use of a deferred-antagonism test showed that S. salivarius strain K12 exhibited the broadest spectrum of activity against GBS. K12 effectively inhibited all GBS strains tested, including disease-implicated isolates from newborns and colonizing isolates from the vaginal tract of pregnant women. Inhibition was dependent on the presence of megaplasmid pSsal-K12, which encodes the bacteriocins salivaricin A and salivaricin B; however, in coculture experiments, GBS growth was impeded by K12 independently of the megaplasmid. We also demonstrated that K12 adheres to and invades human vaginal epithelial cells at levels comparable to GBS. Inhibitory activity of K12 was examined in vivo using a mouse model of GBS vaginal colonization. Mice colonized with GBS were treated vaginally with K12. K12 administration significantly reduced GBS vaginal colonization in comparison to nontreated controls, and this effect was partially dependent on the K12 megaplasmid. Our results suggest that K12 may have potential as a preventative therapy to control GBS vaginal colonization and thereby prevent its transmission to the neonate during pregnancy. PMID:26077762

    Bacterial communities colonizing the reproductive tracts of primates (including humans) impact the health, survival and fitness of the host, and thereby the evolution of the host species. Despite their importance, we currently have a poor understanding of primate microbiomes. The composition and structure of microbial communities vary considerably depending on the host and environmental factors. We conducted comparative analyses of the primate vaginal microbiome using pyrosequencing of the 16S rRNA genes of a phylogenetically broad range of primates to test for factors affecting the diversity of primate vaginal ecosystems. The nine primate species included: humans (Homo sapiens), yellow baboons (Papio cynocephalus), olive baboons (Papio anubis), lemurs (Propithecus diadema), howler monkeys (Alouatta pigra), red colobus (Piliocolobus rufomitratus), vervets (Chlorocebus aethiops), mangabeys (Cercocebus atys) and chimpanzees (Pan troglodytes). Our results indicated that all primates exhibited host-specific vaginal microbiota and that humans were distinct from other primates in both microbiome composition and diversity. In contrast to the gut microbiome, the vaginal microbiome showed limited congruence with host phylogeny, and neither captivity nor diet elicited substantial effects on the vaginal microbiomes of primates. Permutational multivariate analysis of variance and Wilcoxon tests revealed correlations among vaginal microbiota and host species-specific socioecological factors, particularly related to sexuality, including: female promiscuity, baculum length, gestation time, mating group size and neonatal birth weight. The proportion of unclassified taxa observed in nonhuman primate samples increased with phylogenetic distance from humans, indicative of the existence of previously unrecognized microbial taxa. These findings contribute to our understanding of host-microbe variation and coevolution, microbial biogeography, and disease risk, and have important implications for the use of animal models in studies of human sexual and reproductive diseases.

    Postmenopausal vaginal atrophy, resulting from decreased estrogen production, frequently requires treatment. Estrogen preparations provide the most effective treatment; local application is preferred to systemic drugs when treating only vaginal symptoms. As local estrogen therapies have comparable efficacy, this study aimed to understand treatment practices, assess experiences with different forms of local estrogen-delivering applicators, and evaluate satisfaction. Women who were US residents aged ?18 years, menopausal (no spontaneous menstrual period for ?1 year or with a double oophorectomy), and receiving local estrogen therapy for 16 months (vaginal cream [supplied with a reusable applicator] or vaginal tablets [supplied with a single-use/disposable applicator]), completed an online questionnaire. Data from 200 women (100 cream users and 100 tablet users; mean therapy duration 3.48 months) showed that most stored medication in the room in which it was applied (88%) and applied it at bedtime (71%), a procedure for which cream users required, on average, more than twice the time of tablet users (5.08 minutes versus 2.48 minutes). Many cream users applied larger-than-prescribed amounts of cream, attempting to achieve greater efficacy (42%), or lower-than-recommended doses (45%), most frequently to avoid messiness (33%) or leakage (30%). More tablet users (69%) than cream users (14%) were extremely satisfied with their applicator. Postmenopausal women using local estrogen therapy were generally more satisfied with the application of vaginal tablets than cream. Patient satisfaction may help to facilitate accurate dosing. Positive perceptions of medication will help to optimize treatment, which, although not assessed in this study, is likely, in turn, to improve vaginal health. PMID:24648772

    Gels are one of the soft material platforms being evaluated to deliver topically acting anti-HIV drugs (microbicides) to the vaginal environment. For each drug, its loaded concentration, gel properties and applied volume, and frequency of dosing can be designed to optimize PK and, thence, PD. These factors also impact user sensory perceptions and acceptability. Deterministic compartmental modeling of vaginal deployment and drug delivery achieved by test gels can help delineate how multiple parameters characterizing drug, vehicle, vaginal environment, and dosing govern details of PK and PD and also gel leakage from the canal. Such microbicide delivery is a transport process combining convection, e.g., from gel spreading along the vaginal canal, with drug diffusion in multiple compartments, including gel, mucosal epithelium, and stroma. The present work builds upon prior models of gel coating flows and drug diffusion (without convection) in the vaginal environment. It combines and extends these initial approaches in several key ways, including: (1) linking convective drug transport due to gel spreading with drug diffusion and (2) accounting for natural variations in dimensions of the canal and the site of gel placement therein. Results are obtained for a leading microbicide drug, tenofovir, delivered by three prototype microbicide gels, with a range of rheological properties. The model includes phosphorylation of tenofovir to tenofovir diphosphate (which manifests reverse transcriptase activity in host cells), the stromal concentration distributions of which are related to reference prophylactic values against HIV. This yields a computed summary measure related to gel protection ("percent protected"). Analyses illustrate tradeoffs amongst gel properties, drug loading, volume and site of placement, and vaginal dimensions, in the time and space history of gel distribution and tenofovir transport to sites of its anti-HIV action and concentrations and potential prophylactic actions of tenofovir diphosphate therein.

    Objective Lactobacillus dominates the lower genital tract microbiota of many women, producing a low vaginal pH, and is important for healthy pregnancy outcomes and protection against several sexually transmitted pathogens. Yet, factors that promote Lactobacillus remain poorly understood. We hypothesized that the amount of free glycogen in the lumen of the lower genital tract is an important determinant of Lactobacillus colonization and a low vaginal pH. Methods Free glycogen in lavage samples was quantified. Pyrosequencing of the 16S rRNA gene was used to identify microbiota from 21 African American women collected over 811 years. Results Free glycogen levels varied greatly between women and even in the same woman. Samples with the highest free glycogen had a corresponding median genital pH that was significantly lower (pH 4.4) than those with low glycogen (pH 5.8; p<0.001). The fraction of the microbiota consisting of Lactobacillus was highest in samples with high glycogen versus those with low glycogen (median?=?0.97 vs. 0.05, p<0.001). In multivariable analysis, having 1 vs. 0 male sexual partner in the past 6 months was negatively associated, while BMI ?30 was positively associated with glycogen. High concentrations of glycogen corresponded to higher levels of L. crispatus and L. jensenii, but not L. iners. Conclusion These findings show that free glycogen in genital fluid is associated with a genital microbiota dominated by Lactobacillus, suggesting glycogen is important for maintaining genital health. Treatments aimed at increasing genital free glycogen might impact Lactobacillus colonization. PMID:25033265

    We investigated the protective role of antibodies in vaginal secretions of mice that were immune to vaginal challenge with herpes simplex virus type 2 (HSV-2). Unfractionated vaginal immunoglobulins from immune and nonimmune mice and affinity-purified immunoglobulin G (IgG) and secretory IgA (S-IgA) from immune secretions were adjusted to their concentrations in vivo. Wild-type HSV-2 was incubated in the immunoglobulin preparations for 15 min in vitro, followed by inoculation into vaginae of nonimmune mice. HSV-2 was neutralized by unfractionated antibody and purified IgG from immune secretions but not by unfractionated nonimmune antibody or by purified immune S-IgA. The protective effect of IgG in vivo was investigated by passively transferring purified serum IgG from immune and nonimmune donors to nonimmune recipients before vaginal challenge infection. Immune IgG significantly reduced the percentage of vaginal epithelium infected, concentrations of shed virus protein in the vaginal lumen, and illness scores, even though the viral antibody titers in serum and vaginal secretions of recipient mice at the time of challenge were only 29 and 8%, respectively, of those in actively immunized mice. Additionally, removal of vaginal secretions from immune mice 10 min before vaginal challenge with HSV-2 significantly increased the concentration of shed virus protein in the vaginal lumen after challenge. Collectively, the data indicate that IgG antibody in vaginal secretions of immune mice provides early protection against vaginal challenge infection, probably by neutralizing virus in the vaginal lumen. In contrast, S-IgA antibody contributed relatively little to immune protection of the vagina. PMID:9343160

  7. Vaginal dilator therapy for women receiving pelvic radiotherapy

    Miles, Tracie; Johnson, Nick

    2014-01-01

    Background Many vaginal dilator therapy guidelines advocate routine vaginal dilation during and after pelvic radiotherapy to prevent stenosis (abnormal narrowing of the vagina). The UK Gynaecological Oncology Nurse Forum recommend dilation three times weekly for an indefinite time period. The UK patient charity Cancer Backup advises using vaginal dilators from two to eight weeks after the end of radiotherapy treatment. Australian guidelines recommend dilation after brachytherapy as soon as is comfortably possible and certainly within four weeks and to continue for three years or indefinitely if possible. However, dilation is intrusive, uses health resources and can be psychologically distressing. It has also caused rare but very serious damage to the rectum. Objectives To review the benefits and harms of vaginal dilation therapy associated with pelvic radiotherapy for cancer. Search methods Searches included the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2008, Issue 4), MEDLINE (1950 to 2008), EMBASE (1980 to 2008) and CINAHL (1982 to 2008). Selection criteria Any comparative randomised controlled trials (RCT) or data of any type which compared dilation or penetration of the vagina after pelvic radiotherapy treatment for cancer. Data collection and analysis The review authors independently abstracted data and assessed risk of bias. We analysed the mean difference in sexual function scores and the risk ratio for non-compliance at six weeks and three months in single trial analyses. No trials met the inclusion criteria. Main results Dilation during or immediately after radiotherapy can, in rare cases, cause damage and there is no persuasive evidence from any study to demonstrate that it prevents stenosis. Data from one RCT showed no improvement in sexual scores in women who were encouraged to practice dilation. Two case series and one comparative study using historical controls suggest that dilation might be associated with a longer vaginal length but these data cannot reasonably be interpreted to show that dilation caused the change in the vagina. Authors conclusions Routine dilation during or soon after cancer treatment may be harmful. There is no reliable evidence to show that routine regular vaginal dilation during or after radiotherapy prevents the late effects of radiotherapy or improves quality of life. Gentle vaginal exploration might separate the vaginal walls before they can stick together and some women may benefit from dilation therapy once inflammation has settled but there are no good comparative supporting data.

  8. Laparoscopic sterilizations (16,803) without vaginal manipulation.

    1982-08-01

    Laparoscopic sterilization is usually done after viewing the fallopian tubes brought into the laparoscopic field by a uterine manipulator introduced through the vagina. The orthodox rural Indian women, however, resent vaginal manipulation exposing their genitalia. Therefore, the author developed a single-puncture technique for performing laparoscopic sterilization with a Falope-Ring, which dispenses with a uterine manipulator. Experience with 16,803 cases is presented. This technique is recommended for mass sterilizations because it eliminates the risks involved in vaginal manipulation and enhances acceptability and popularity of the procedure. Nonetheless, the risks of bowel injury are augmented, and the method is not for the inexperienced or occasional operator. PMID:6127267

    OBJECTIVES: The meta-analysis described here reviewed the current literature on adverse health effects of vaginal douching. METHODS: Papers published in English from 1965 through 1995 were potentially eligible. RESULTS: One third of White women and two thirds of Black women of reproductive age reported douching regularly. Analyses indicated that vaginal douching increases the overall risk of pelvic inflammatory disease by 73% and the risk of ectopic pregnancy by 76%. Frequent douching was shown to be highly associated with pelvic inflammatory disease and modestly associated with cervical cancer. CONCLUSIONS: Current literature suggests that frequent douching increases the risk of pelvic inflammatory disease, ectopic pregnancy, and, possibly, cervical cancer. PMID:9240115

    While most obstetricians are familiar with fracture of the clavicle in newborns during birth, an unlucky minority of obstetricians has encountered long-bone fractures in newborns as well. This complication is traumatic not only for the neonate, but also for the family and the obstetrician; it is also difficult to explain. Fortunately, the long-term prognosis for fracture of the long bones is excellent. Both vaginal and cesarean breech deliveries and maneuvers can be responsible for birth traumas, including long-bone fractures. This case report presents a newborn with breech presentation delivered vaginally that resulted in humerus diaphysis fracture. PMID:26770851

    The authors described the results of treatment of vaginal cysts with CO2 laser under colposcopic control in 12 women. In five of them the recurrent Bartholin's, in another five the Gartner's and in tow the endometrial cysts were diagnosed. All laser surgeries were done in the Department of Reproduction, Institute of Gynecology, Karol Marcinkowski School of Medical Sciences, Poznan, Poland between September 1995 and September 1996. In the authors' opinion the use of CO2 laser is the efficient method of treatment of vaginal cysts. The most of laser procedures are doing as the one-day surgery. There are no serious postoperative complications after laser surgery.

  19. Comparison of the moisturization efficacy of two vaginal moisturizers: Pectin versus polycarbophil technologies.

    PubMed

    Caswell, Michael; Kane, Michael

    2002-01-01

    This study was designed to compare the vaginal deposition and moisturization of two vaginal moisturizers, Summer's Eve (SE), based on pectin, and Replens (Rp), based on polycarbophil, in a double-blind crossover study design. Fifty-one female patients were each randomly assigned to one of two treatment groups. After a one-week washout period, the products were used for two weeks. After another one-week washout period, product assignments were switched. Colposcopy examinations were performed at the beginning and at the end of each product use. Of the forty-seven patients completing the study, 41 (87%) were found to have no vaginal residue after SE vaginal moisturizer, while only 25 (53%) were found to have no vaginal residue after using Rp vaginal moisturizer. No difference in relief of vaginal dryness or in product acceptance was found between the two products. This study shows that the use of SE vaginal moisturizer, based on pectin, resulted in significantly less vaginal residue compared to Rp vaginal moisturizer, based on polycarbophil, and in comparable relief of vaginal dryness. These results strongly suggest that bioadhesion is not important in vaginal moisturizers. PMID:11919643

    Objective: To compare the outcomes of luteal phase support by micronized progesteron vaginal capsule 600mg/day and progesterone vaginal gel 180mg/day in the normoresponder IVF/ICSI-ET cycles of the patients down-regulated via GnRH agonist long protocol or fixed antagonist protocol below 40 years of age. Methods: A total of 463 normoresponder cycles between January 2013 and December 2013 were retrospectively analyzed. Those with a BMI>28 kg/m2, any kind of uterine, ovarian or adnexial pathology, any significant systemic, endocrine or metabolic disease or who were reported as azoospermia, were excluded from the study. The patients were grouped according to the usage of micronized progesterone vaginal capsule 600mg/day (Group 1) or progesterone vaginal gel 180mg/day (Group 2) as luteal phase support. Treatment cycle characteristics and pregnancy outcomes were compared between groups. Results: Group-I included 220 cycles and group 2 included 243 cycles. Although the MII oocyte percentage among the total number of MII oocytes was significantly higher in Group-II (77.5% and 80.2%; p=0.034), positive ß-hCG (32.3% and 21.8%; p=0.015) and clinical pregnancy (27.3% and 17.7%; p=0.018) rates were significantly higher in Group-I. No difference was observed between groups regarding the ongoing pregnancy rates (23.2% and 17.3%; p=0.143). Conclusion: Micronized progesterone vaginal capsule 600mg daily used for luteal support in the IVF/ICSI-ET cycles was observed to significantly increase the biochemical and clinical pregnancy rates compared to progesterone vaginal gel 180mg daily. However, no difference was observed between two groups regarding ongoing pregnancy rates. PMID:26101482

    Reproductive tract infection is a major initiator of preterm birth (PTB). The objective of this prospective cohort study of 88 participants was to determine whether PTB correlates with the vaginal microbiome during pregnancy. Total DNA was purified from posterior vaginal fornix swabs during gestation. The 16S ribosomal RNA gene was amplified using polymerase chain reaction primers, followed by chain-termination sequencing. Bacteria were identified by comparing contig consensus sequences with the Ribosomal Database Project. Dichotomous responses were summarized via proportions and continuous variables via means ± standard deviation. Mean Shannon Diversity index differed by Welch t test (P = .00016) between caucasians with PTB and term gestation. Species diversity was greatest among African Americans (P = .0045). Change in microbiome/Lactobacillus content and presence of putative novel/noxious bacteria did not correlate with PTB. We conclude that uncultured vaginal bacteria play an important role in PTB and race/ethnicity and sampling location are important determinants of the vaginal microbiome. PMID:23715799

    Lectins are carbohydrate-binding proteins of non-imune origin. This group of proteins is distributed widely in nature and they have been found in viruses, microorganisms, plants and animals. Lectins of plants have been isolated and characterized according to their chemical, physical-chemical, structural and biological properties. Among their biological activities, we can stress its fungicidal action. It has been previously described the effect of the lectins Dviol, DRL, ConBr and LSL obtained from the seeds of leguminous plants on the growth of yeasts isolated from vaginal secretions. In the present work the experiments were carried out in microtiter plates and the results interpreted by both methods: visual observations and a microplate reader at 530nm. The lectin concentrations varied from 0.5 to 256?g/mL, and the inoculum was established between 65-70% of trammitance. All yeast samples isolated from vaginal secretion were evaluated taxonomically, where were observed macroscopic and microscopic characteristics to each species. The LSL lectin did not demonstrate any antifungal activity to any isolate studied. The other lectins DRL, ConBr and DvioL, showed antifungal potential against yeast isolated from vaginal secretion. These findings offering offer a promising field of investigation to develop new therapeutic strategies against vaginal yeast infections, collaborating to improve women's health. PMID:24031889

  3. Vaginal Approaches Using Synthetic Mesh to Treat Pelvic Organ Prolapse

    PubMed Central

    Moon, Jei Won

    2016-01-01

    Pelvic organ prolapse (POP) is a very common condition in elderly women. In women with POP, a sacrocolpopexy or a vaginal hysterectomy with anterior and posterior colporrhaphy has long been considered as the gold standard of treatment. However, in recent decades, the tendency to use a vaginal approach with mesh for POP surgery has been increasing. A vaginal approach using mesh has many advantages, such as its being less invasive than an abdominal approach and easier to do than a laparoscopic approach and its having a lower recurrence rate than a traditional approach. However, the advantages of a vaginal approach with mesh for POP surgery must be weighed against the disadvantages. Specific complications that have been reported when using mesh in POP procedures are mesh erosion, dyspareunia, hematomas, urinary incontinence and so on, and evidence supporting the use of transvaginal surgery with mesh is still lacking. Hence, surgeons should understand the details of the surgical pelvic anatomy, the various surgical techniques for POP surgery, including using mesh, and the possible side effects of using mesh.

    Changes in reproductive status place varied functional demands on the vagina. These include receptivity to male intromission and sperm transport in estrus, barrier functions during early pregnancy, and providing a conduit for fetal passage at parturition. Peripheral innervation regulates vaginal function, which in turn may be influenced by circulating reproductive hormones. We assessed vaginal innervation in diestrus and estrus (before and after the estrous cycle surge in estrogen), and in the early (low estrogen) and late (high estrogen) stages in pregnancy. In vaginal sections from cycling rats, axons immunoreactive for the pan-neuronal marker protein gene product 9.5 (PGP 9.5) showed a small reduction at estrus relative to diestrus, but this difference did not persist after correcting for changes in target size. No changes were detected in axons immunoreactive for tyrosine hydroxylase (sympathetic), vesicular acetylcholine transporter (parasympathetic), or calcitonin gene-related peptide and transient receptor potential vanilloid type 1 (TRPV-1; sensory nociceptors). In rats at 10 days of pregnancy, innervation was similar to that observed in cycling rats. However, at 21 days of pregnancy, axons immunoreactive for PGP 9.5 and each of the subpopulation-selective markers were significantly reduced both when expressed as percentage of sectional area or after correcting for changes in target size. Because peripheral nerves regulate vaginal smooth muscle tone, blood flow, and pain sensitivity, reductions in innervation may represent important adaptive mechanisms facilitating parturition.

    Development of female genito-urinary infections depends on many factors, such as immune system activity, virulence of microorganism and production of factors inhibiting the growth of microorganisms. Taking into account the possibility of relapses or severe complications, it is very important to appropriately diagnose and treat infections. Because of recently observed increase of microbial resistance to antibiotics, researchers are looking for alternatives. In our study we evaluated and compared the concentration of human neutrophil peptides (HNP 1-3) in cervico-vaginal lavages (CVL), obtained from women with vaginitis/cervicitis. Swabs from the posterior vaginal fornix and from the endocervical canal as well as CVL samples were obtained from 32 patients with vaginitis/cervicitis and 29 healthy women (control group). Supernatants of CVL were used for determination of concentration of HNP by ELISA. The difference between concentrations of HNP 1-3 in studied and control groups was statistically significant (p = 0.018). The maximal concentration was determined in patients with mixed infections (28.41 ng/ml), and Group B Streptococci, GBS, (28.06 ng/ml), the minimal concentrations in cases of C. trachomatis (mean concentrations did not differ from those in the control group: 16.93 ng/ml and 16.39 ng/ml, respectively). Maximal correlation was determined for control-studied group with isolation of GBS (r = 0.79), and very high negative correlation for group of GBS - C. trachomatis (r = -0.98). PMID:18062652

    Aim: Aim of the study was to show that conservative management with preservation of the uterus and of fertility is possible in patients with placenta accreta/increta after vaginal delivery. Method: A retrospective analysis of patients with placental attachment disorders after vaginal delivery was done in a perinatal centre between November 2009 and April 2011. The patient collective was identified using the ICD-10 codes for placenta accreta/increta/percreta, and patient records were analysed for risk factors, maternal morbidity, preservation of the uterus and of fertility, and neonatal outcome. Results: Three cases of placenta increta were identified in the last 1.5 years out of a total of 1457 vaginal deliveries, and all 3 cases were treated conservatively. Mean maternal age was 35.3 years; gestational age ranged from 39 to 41 weeks, and mean duration between delivery of the child and delivery of the placenta was 44.67 days (range: 14-100 days). Two patients developed symptoms of endomyometritis, including fever, leukocytosis and increased CRP levels. All 3 women were successfully managed with preservation of the uterus. Conclusion: In selected cases with placenta accreta/increta after vaginal delivery, it is possible to avoid surgical procedures, particularly hysterectomy procedures, and successfully manage these patients conservatively with preservation of the uterus.

    Background. Vaginal practices (VPs) may increase HIV risk by injuring vaginal epithelium or by increasing risk of bacterial vaginosis, an established risk factor for HIV. Methods. HIV-negative Zimbabwean women (n = 2,185) participating in a prospective study on hormonal contraception and HIV risk completed an ancillary questionnaire capturing detailed VP data at quarterly followup visits for two years. Results. Most participants (84%) reported ever cleansing inside the vagina, and at 40% of visits women reported drying the vagina using cloth or paper. Vaginal tightening using cloth/cotton wool, lemon juice, traditional herbs/powders, or other products was reported at 4% of visits. Women with ≥15 unprotected sex acts monthly had higher odds of cleansing (adjusted odds ratio (aOR): 1.17, 95% CI: 1.04–1.32). Women with sexually transmitted infections had higher odds of tightening (aOR: 1.42, 95% CI: 1.08–1.86). Conclusion. Because certain vaginal practices were associated with other HIV risk factors, synergism between VPs and other risk factors should be explored. PMID:20871844

    Preemptive analgesia in vaginal surgery has had conflicting efficacy reported in the existing literature. This study was designed to clarify the usefulness of preemptive local analgesia (PLA) in patients undergoing vaginal hysterectomy. A prospective, randomized, double-blinded trial of PLA in 90 women undergoing vaginal hysterectomy was conducted. PLA consisted of 20 ml of 0.5% bupivacaine with 1:200,000 epinephrine injected in a paracervical-type fashion. Total narcotic use and pain (using a visual analog scale (VAS)) was recorded at 30 min, 3, 12, and 24 h postoperatively. The mean total dose of narcotic was significantly less in the PLA group versus the placebo group (P = 0.009) at every time point postoperatively. Additionally, the mean pain VAS 30 min and 3 h postoperatively was 43% (P = 0.003) and 33% (P = 0.02) lower, respectively, in the PLA group. PLA with bupivacaine prior to vaginal hysterectomy is associated with significantly lower pain scores and a reduction in narcotic use postoperatively. PMID:18830553

    Vaginal angiomatosis is regarded as part of a very rare entity of benign vascular tumors of the female genital tract. The incidence of these tumors is extremely low. The rarity of this disease and lack of distinctive features poses a problem of differential diagnosis. We present the case of a 51-year-old female with grade III uterine prolapse and a bleeding vaginal wall mass. Violaceous irregular soft tissue with hemorrhagic spots was observed in the lower third of the posterior vaginal wall. The patient underwent surgery for colpohysterectomy with vaginal wall mass excision. Surgical excision was curative, and no recurrences were observed after 12 months of follow-up. The aim of our study is to present a rare but representative case. This will hopefully increase the level of awareness regarding this condition so that physicans will keep it in mind during differential diagnosis of similar clinical cases. Furthermore, it highlights the important role of pathological examination for the definitive diagnosis of angiomatosis. PMID:26401116

    Maybe the worst aspect of menopause is the decline of the quality of the sexual life. The aim of the study is to demonstrate the beneficial effects of laser therapy in comparison with topical application of estrogen preparations, for the treatment of vaginal atrophy and sexual dysfunctions induced by menopause. A total of 50 menopausal patients were examined during a one year period. The methods used for objectifying vaginal atrophy and sexual dysfunctions were history taking, local clinical exam and PAP smear. From this group, 40 patients had vaginal atrophy with sexual dysfunctions. They have been treated differently, being included in four groups: patients treated with local estrogens, patients treated with intravaginal laser therapy, patients treated with both laser therapy and estrogens, patients treated with estrogens and placebo laser therapy. Therapeutic benefit, improvement of vaginal atrophy and quality of sexual life, were objectified by anamnesis (questionnaire), local and general clinical examination and PAP smear. The best results have been obtained, by far, in the 3rd group, followed by the women treated only with laser. In conclusion, we can say that laser therapy is the best way for solving the sexual inconveniences of menopause.

    Vaginal douching is widely practiced by women in the USA, particularly among minority ethnic groups, and is associated with increased risk of pelvic and vaginal infections. Douching practices are shaped by social and cultural norms regarding female hygiene, reproduction, and sexuality. Little previous research has addressed the beliefs and practices of Latina women, and none has included the perspective of men, though limited data suggests that women may douche to please male partners. The present study seeks to identify the socially and culturally shaped beliefs and attitudes that influence douching practices from the perspective of Latino men. We conducted in-depth qualitative interviews in English or Spanish with adult Latino men seeking primary care at a community health centre in New York City (USA). Results indicate that these Latino men (mostly of Caribbean descent) are emphatic about the role of cleanliness in vaginal health, reporting that it substantially influences their choice of partner. Most are very supportive of douching, which they consider a necessary hygiene activity. Vaginal health is perceived as a state that must be attained and maintained through proactive hygiene measures that remove seminal residue, menstrual blood, sweat and bacteria that contaminate the vagina. The implications of these findings for interventions with Latina women are discussed. PMID:19247860

    Vaginal discharge in prepubertal children is mainly due to hypoestrogenic state of vaginal mucosa making it thin and alkaline leading to mucosal invasion by pathogen. In a paediatric case with persistent foul smelling , blood stained vaginal discharge not responding to medical therapy, vaginal foreign body should always be ruled out. Here, we report a 3 -year -old girl with complaint of recurrent vaginal discharge occasionally blood stained not relieved despite few antibiotics courses. On X -ray pelvis, a radioopaque foreign body hair clip was seen. Under sedation foreign body was removed by forceps following which child became asymptomatic. PMID:25738041

    BACKGROUND: Vaginitis is the most prevalent gynecological problem for which women look for treatment and is responsible for 10 million physician visits annually. Use of herbal treatments has been recorded in many of patient groups as well as in general populations to increase health level. The present study was conducted with the purpose of determination and comparison of the effect of vaginal cream containing garlic and thyme compared to clotrimazole cream for the treatment of mycotic vaginitis. METHODS: This clinical trial is a prospective, multivariate, single-blind, two-stage, two-group study with randomized assignment of samples into the two groups. From the clinics in Isfahan in 2010, 64 cases (32 individuals in each group) entered the study. Data collection was accomplished by demographic information questionnaire and clinical performance checklist, and data analysis was performed by SPSS 16.0 software. RESULTS: Abundance distributions of clinical symptoms (vaginal discharge; vulval erythema and edema), patients complaints (secretions, itching, dyspareunia, painful urination, and vaginal irritation) and clinical symptoms (existence of germinating hypha, acidity under 4.5, and culture of vaginal secretions) were different in each group prior to and after the intervention; these factors however were not different between the two groups before and after the intervention. CONCLUSIONS: The vaginal cream containing garlic and thyme is effective as much as clotrimazole vaginal cream for the treatment of candida vaginitis and there is no difference between responses to treatment by these two drugs.

    Backround Vaginitis is among the most common conditions women are seeking medical care for. Although these infections can easily be treated, the relapse rate is high. This may be due to inadequate use of the diagnostic potential. Methods We evaluated the misjudgement rate of the aetiology of vaginal complaints. A total of 220 vaginal samples from women with a vaginal complaint were obtained and analysed for numbers of total lactobacilli, H2O2-producing lactobacilli, total aerobic cell counts and total anaerobic cell counts including bifidobacteria, Bacteroides spp., Prevotella spp. Additionally, the presence of Atopobium vaginae, Gardnerella vaginalis, Candida spp. and Trichomonas vaginalis was evaluated by DNA-hybridisation using the PCR and Affirm VPIII Microbial Identification Test, respectively. Results The participating physicians diagnosed Bacterial vaginosis (BV) as origin of discomfort in 80 cases, candidiasis in 109 cases and mixed infections in 8 cases. However, a present BV, defined as lack of H2O2-lactobacilli, presence of marker organisms, such as G. vaginalis, Bacteroides spp. or Atopobium vaginae, and an elevated pH were identified in only 45 cases of the women examined. Candida spp. were detected in 46 cases. Interestingly, an elevated pH corresponded solely to the presence of Atopobium vaginae, which was detected in 11 cases. Conclusion Errors in the diagnosis of BV and candida vulvovaginitis (CV) were high. Interestingly, the cases of misjudgement of CV (77%) were more numerous than that of BV (61%). The use of Amsel criteria or microscopy did not reduce the number of misinterpretations. The study reveals that the misdiagnosis of vaginal complaints is rather high. PMID:16503990

    In this study, we sought to find novel bacterial and metabolic hallmarks for bacterial vaginosis (BV). We studied the vaginal microbiome and metabolome of vaginal fluids from BV-affected patients (n = 43) and healthy controls (n = 37) by means of an integrated approach based on quantitative polymerase chain reaction (qPCR) and proton nuclear magnetic resonance ((1)H-NMR). The correlations between the clinical condition and vaginal bacterial communities were investigated by principal component analysis (PCA). To define the metabolomics signatures of BV, 100 discriminant analysis by projection on latent structure (PLS-DA) models were calculated. Bacterial signatures distinguishing the health condition and BV were identified by qPCR. Lactobacillus crispatus strongly featured the healthy vagina, while increased concentrations of Prevotella, Atopobium and Mycoplasma hominis specifically marked the infection. (1)H-NMR analysis has led to the identification and quantification of 17 previously unreported molecules. BV was associated with changes in the concentration of metabolites belonging to the families of amines, organic acids, short chain fatty acids, amino acids, nitrogenous bases and monosaccharides. In particular, maltose, kynurenine and NAD(+) primarily characterised the healthy status, while nicotinate, malonate and acetate were the best metabolic hallmarks of BV. This study helps to better understand the role of the vaginal microbiota and metabolome in the development of BV infection. We propose a molecular approach for the diagnosis of BV based on quantitative detection in the vaginal fluids of Atopobium, Prevotella and M. hominis, and nicotinate, malonate and acetate by combining qPCR and (1)H-NMR.

    Melittin is a cytolytic peptide component of bee venom which rapidly integrates into lipid bilayers and forms pores resulting in osmotic lysis. While the therapeutic utility of free melittin is limited by its cytotoxicity, incorporation of melittin into the lipid shell of a perfluorocarbon nanoparticle has been shown to reduce its toxicity in vivo. Our group has previously demonstrated that perfluorocarbon nanoparticles containing melittin at concentrations <10 M inhibit HIV infectivity in vitro. In the current study, we assessed the impact of blank and melittin-containing perfluorocarbon nanoparticles on sperm motility and the viability of both sperm and vaginal epithelial cells. We found that free melittin was toxic to sperm and vaginal epithelium at concentrations greater than 2 M (p<0.001). However, melittin nanoparticles were not cytotoxic to sperm (p?=?0.42) or vaginal epithelium (p?=?0.48) at an equivalent melittin concentration of 10 M. Thus, nanoparticle formulation of melittin reduced melittin cytotoxicity fivefold and prevented melittin toxicity at concentrations previously shown to inhibit HIV infectivity. Melittin nanoparticles were toxic to vaginal epithelium at equivalent melittin concentrations ?20 M (p<0.001) and were toxic to sperm at equivalent melittin concentrations ?40 M (p<0.001). Sperm cytotoxicity was enhanced by targeting of the nanoparticles to the sperm surface antigen sperm adhesion molecule 1. While further testing is needed to determine the extent of cytotoxicity in a more physiologically relevant model system, these results suggest that melittin-containing nanoparticles could form the basis of a virucide that is not toxic to sperm and vaginal epithelium. This virucide would be beneficial for HIV serodiscordant couples seeking to achieve natural pregnancy. PMID:24748389

    Incomplete coverage and short duration of action limit the effectiveness of vaginally administered drugs, including microbicides for preventing sexually transmitted infections. We investigated vaginal distribution, retention, and safety of nanoparticles with surfaces modified to enhance transport through mucus. We show that mucus-penetrating particles (MPPs) provide uniform distribution over the vaginal epithelium, whereas conventional nanoparticles (CPs) that are mucoadhesive are aggregated by mouse vaginal mucus, leading to poor distribution. Moreover, when delivered hypotonically, MPPs were transported advectively (versus diffusively) through mucus deep into vaginal folds (rugae) within minutes. By penetrating into the deepest mucus layers, more MPPs were retained in the vaginal tract after 6 h compared to CPs. After 24 h, when delivered in a conventional vaginal gel, patches of a model drug remained on the vaginal epithelium, whereas the epithelium was coated with drug delivered by MPP. We then developed MPPs composed of acyclovir monophosphate (ACVp). When administered prior to vaginal herpes simplex virus 2 (HSV-2) challenge, ACVp-MPPs protected 53% of mice, compared to only 16% protected by soluble drug. Overall, MPPs improved vaginal drug distribution and retention, provided more effective protection against vaginal viral challenge than soluble drug, and were non-toxic when administered daily for one week.

    Vaginitis is the most common female infectious disease. Females suffering from this disorder are annually increasing in number. There are a lot of modalities of treatment of vaginitis, but because of drug allergy and microbe's stability to drug the treatment of vaginitis is difficult. Our study compares the efficacy of laser-therapy with drug therapy in the treatment of non-specific vaginitis and vaginal candidiasis. Thirty women reci4eed the LLLT by local action with antiseptic liquid daily during ten days, 20 women received metronidazole and fluconozole and vaginal application of metronidazole. The results suggest that local laser-therapy is able to remove sights of vaginitis more efficiently and faster than drug therapy. Repair of normal vaginal microflora, which is the best indicator of recovery, was significantly at a faster rate in laser-therapy group. There were no report of adverse reaction with vaginal laser- therapy, whereas there were women on drug therapy who reported side effects. In conclusion, vaginal aser-therapy with antiseptic liquid is a suitable, effective, safe and chip alternative to drug therapy in the treatment of vaginitis.

    Objective Vaginal colonization with Lactobacillus species is characteristic of normal vaginal ecology. The absence of vaginal lactobacilli, particularly hydrogen peroxide (H2O2)-producing isolates, has been associated with symptomatic bacterial vaginosis (BV) and increased risk for HIV-1 acquisition. Identification of factors associated with vaginal Lactobacillus colonization may suggest interventions to improve vaginal health. Methods We conducted a prospective cohort study of correlates of vaginal Lactobacillus colonization among Kenyan HIV-1 seronegative female sex workers. At monthly follow-up visits, vaginal Lactobacillus cultures were obtained. Generalized estimating equations were used to examine demographic, behavioral, and medical correlates of Lactobacillus isolation, including isolation of H2O2-producing strains. Results Lactobacillus cultures were obtained from 1020 women who completed a total of 8896 follow-up visits. Vaginal washing, typically with water alone or with soap and water, was associated with an approximately 40% decreased likelihood of Lactobacillus isolation, including isolation of H2O2-producing strains. Recent antibiotic use, excluding metronidazole and treatments for vaginal candidiasis, reduced Lactobacillus isolation by ~30%. H2O2-producing lactobacilli were significantly less common among women with Trichomonas vaginalis infection and those who were seropositive for herpes simplex virus type 2. In contrast, H2O2-producing lactobacilli were significantly more common among women with concurrent vaginal candidiasis. Conclusions Modifiable biologic and behavioral factors are associated with Lactobacillus colonization in African women. Our results suggest intervention strategies to improve vaginal health in women at high risk for HIV-1. PMID:19329442

    Successful vaginal birth after cesarean section is more comfortable than repeat emergency or elective cesarean section. Antenatal examinations are important in selection for trial of labor, while birth management can be difficult when the patients present at emergency condition. But there is an increased chance of vaginal birth with advanced cervical dilation. This study attempts to evaluate factors associated with success of vaginal birth after cesarean section and to compare the maternal and perinatal outcomes between vaginal birth after cesarean section and intrapartum cesarean section in patients who were admitted to hospital during the active or second stage of labor. A retrospective evaluation was made from the results of 127 patients. Cesarean section was performed in 57 patients; 70 attempted trial of labor. The factors associated with success of vaginal birth after cesarean section were investigated. Maternal and neonatal outcomes were compared between the groups. Vaginal birth after cesarean section was successful in 55% of cases. Advanced cervical opening, effacement, gravidity, parity, and prior vaginal delivery were factors associated with successful vaginal birth. The vaginal birth group had more complications (P<0.01), but these were minor. The rate of blood transfusion and prevalence of changes in hemoglobin level were similar in both groups (P>0.05). In this study, cervical opening, effacement, gravidity, parity, and prior vaginal delivery were important factors for successful vaginal birth after cesarean section. The patients' requests influenced outcome. Trial of labor should take into consideration the patient's preference, together with the proper setting. PMID:26203286

    Despite availability of successful prevention strategies, HIV continues to spread at alarming rates, especially among women in developing countries. Vaginal microbicides offer a promising approach for blocking transmission of HIV when condom use cannot be negotiated with male partners. A major problem in the development of vaginal microbicides is chemically induced vaginal irritation, which can enhance the risk of HIV transmission. Evaluation of vaginal irritation prior to clinical trials typically uses an expensive and animal-intensive rabbit vaginal irritation model, which could be supplemented by measuring additional inflammatory biomarkers. We studied several immunological parameters as potential biomarkers of vaginal irritation, using the spermicides nonoxynol-9 and benzalkonium chloride as test microbicides. We measured amounts of cytokines, as well as inflammatory cells, in vaginal tissue lysates and on the vaginal surface. We observed that treatment with the selected microbicides increases quantities of the inflammatory cytokines interleukin-1?, CXCL8, and CCL2 in the vaginal tissue parenchyma, and of CCL2 on the vaginal surface. This observation was correlated with increases in macrophages in the vaginal parenchyma. We suggest that measurements of CCL2 and macrophages can serve as new inflammatory biomarkers to evaluate the safety of promising novel microbicides for prevention of HIV. PMID:19929801

    Topical administration of clotrimazole represents the common use therapy in the antimycotic genitourinary tract treatment. Due to the fast self-cleaning action of the vagina, commercially available vaginal dosage forms with clotrimazole cannot assure prolonged contact time with mucosa, therefore the main objective of this study was to develop a dosage form for vaginal administration of clotrimazole using chitosan-a biodegradable and biocompatible derivative of chitin. Tablets mucoadhesive properties were examined using texture analyser under the presence of porcine vaginal mucosa and two different models of adhesive layers- mucin gel and gelatine discs. In addition, friability, hardness, swelling behaviour, residence time, surface morphology of the performed tablets, the in vitro release profile of clotrimazole and clotrimazole release kinetics were determined. The release of clotrimazole from formulations with 25 or 40% of chitosan (F2 and F3) followed non Fickian diffusion through chitosan-gel layer and was retarded up to 6 h. Additionally, tablets F2 showed the best results in terms of mucoadhesive properties and appeared to be a good alternative to commercially available antimycotic vaginal dosage forms. PMID:24492586

  11. Identification and genotyping of bacteria from paired vaginal and rectal samples from pregnant women indicates similarity between vaginal and rectal microflora

    PubMed Central

    2009-01-01

    Background The vaginal microflora is important for maintaining vaginal health and preventing infections of the reproductive tract. The rectum has been suggested as the major source for the colonisation of the vaginal econiche. Methods To establish whether the rectum can serve as a possible bacterial reservoir for colonisation of the vaginal econiche, we cultured vaginal and rectal specimens from pregnant women at 35-37 weeks of gestation, identified the isolates to the species level with tRNA intergenic length polymorphism analysis (tDNA-PCR) and genotyped the isolates for those subjects from which the same species was isolated simultaneously vaginally and rectally, by RAPD-analysis. One vaginal and one rectal swab were collected from a total of each of 132 pregnant women at 35-37 weeks of gestation. Swabs were cultured on Columbia CNA agar and MRS agar. For each subject 4 colonies were selected for each of both sites, i.e. 8 colonies in total. Results Among the 844 isolates that could be identified by tDNA-PCR, a total of 63 bacterial species were present, 9 (14%) only vaginally, 26 (41%) only rectally, and 28 (44%) in both vagina and rectum. A total of 121 (91.6%) of 132 vaginal samples and 51 (38.6%) of 132 rectal samples were positive for lactobacilli. L. crispatus was the most frequently isolated Lactobacillus species from the vagina (40% of the subjects were positive), followed by L. jensenii (32%), L. gasseri (30%) and L. iners (11%). L. gasseri was the most frequently isolated Lactobacillus species from the rectum (15%), followed by L. jensenii (12%), L. crispatus (11%) and L. iners (2%). A total of 47 pregnant women carried the same species vaginally and rectally. This resulted in 50 vaginal/rectal pairs of the same species, for a total of eight different species. For 34 of the 50 species pairs (68%), isolates with the same genotype were present vaginally and rectally and a high level of genotypic diversity within species per subject was also established. Conclusion It can be concluded that there is a certain degree of correspondence between the vaginal and rectal microflora, not only with regard to species composition but also with regard to strain identity between vaginal and rectal isolates. These results support the hypothesis that the rectal microflora serves as a reservoir for colonisation of the vaginal econiche. PMID:19828036

    Background Oral and vaginal preparations of tenofovir as pre-exposure prophylaxis (PrEP) for human immunodeficiency virus (HIV) infection have demonstrated variable efficacy in men and women prompting assessment of variation in drug concentration as an explanation. Knowledge of tenofovir concentration and its active form, tenofovir diphosphate, at the putative vaginal and rectal site of action and its relationship to concentrations at multiple other anatomic locations may provide key information for both interpreting PrEP study outcomes and planning future PrEP drug development. Objective MTN-001 was designed to directly compare oral to vaginal steady-state tenofovir pharmacokinetics in blood, vaginal tissue, and vaginal and rectal fluid in a paired cross-over design. Methods and Findings We enrolled 144 HIV-uninfected women at 4 US and 3 African clinical research sites in an open label, 3-period crossover study of three different daily tenofovir regimens, each for 6 weeks (oral 300 mg tenofovir disoproxil fumarate, vaginal 1% tenofovir gel [40 mg], or both). Serum concentrations after vaginal dosing were 56-fold lower than after oral dosing (p<0.001). Vaginal tissue tenofovir diphosphate was quantifiable in ≥90% of women with vaginal dosing and only 19% of women with oral dosing. Vaginal tissue tenofovir diphosphate was ≥130-fold higher with vaginal compared to oral dosing (p<0.001). Rectal fluid tenofovir concentrations in vaginal dosing periods were higher than concentrations measured in the oral only dosing period (p<0.03). Conclusions Compared to oral dosing, vaginal dosing achieved much lower serum concentrations and much higher vaginal tissue concentrations. Even allowing for 100-fold concentration differences due to poor adherence or less frequent prescribed dosing, vaginal dosing of tenofovir should provide higher active site concentrations and theoretically greater PrEP efficacy than oral dosing; randomized topical dosing PrEP trials to the contrary indicates that factors beyond tenofovir’s antiviral effect substantially influence PrEP efficacy.

  13. Selecting anti-microbial treatment of aerobic vaginitis.

    PubMed

    2015-05-01

    Aerobic vaginitis (AV) is a vaginal infectious condition which is often confused with bacterial vaginosis (BV) or with the intermediate microflora as diagnosed by Nugent's method to detect BV on Gram-stained specimens. However, although both conditions reflect a state of lactobacillary disruption in the vagina, leading to an increase in pH, BV and AV differ profoundly. While BV is a noninflammatory condition composed of a multiplex array of different anaerobic bacteria in high quantities, AV is rather sparely populated by one or two enteric commensal flora bacteria, like Streptococcus agalactiae, Staphylocuccus aureus, or Escherichia coli. AV is typically marked by either an increased inflammatory response or by prominent signs of epithelial atrophy or both. The latter condition, if severe, is also called desquamative inflammatory vaginitis. As AV is per exclusionem diagnosed by wet mount microscopy, it is a mistake to treat just vaginal culture results. Vaginal cultures only serve as follow-up data in clinical research projects and are at most used in clinical practice to confirm the diagnosis or exclude Candida infection. AV requires treatment based on microscopy findings and a combined local treatment with any of the following which may yield the best results: antibiotic (infectious component), steroids (inflammatory component), and/or estrogen (atrophy component). In cases with Candida present on microscopy or culture, antifungals must be tried first in order to see if other treatment is still needed. Vaginal rinsing with povidone iodine can provide rapid relief of symptoms but does not provide long-term reduction of bacterial loads. Local antibiotics most suitable are preferably non-absorbed and broad spectrum, especially those covering enteric gram-positive and gram-negative aerobes, like kanamycin. To achieve rapid and short-term improvement of severe symptoms, oral therapy with amoxyclav or moxifloxacin can be used, especially in deep dermal vulvitis and colpitis infections with group B streptococci or (methicillin resistant) Staphylococcus aureus. Since the latter colonizations are frequent, but seldom inflammatory infections, we in general discourage the use of oral antibiotics in women with AV. In cases with a severe atrophy component (more than 10 % of epithelial cells are of the parabasal type), local estrogens can be used; and in postmenopausal or breast cancer patients with a contraindication for estrogens, even a combination of probiotics with an ultra-low dose of local estriol may be considered.

    Generic guidelines are applied to reconstructive vaginal operations, so as to convert them to ambulatory procedures. Prototype operations are described and analyzed. These included conceptualizing vaginal prolapse as a type of intussusception caused by vaginal and ligamentous laxity in the middle or posterior parts of the vagina; the avoidance of vaginal excision, excessive tension, and refashioning excess vaginal tissue from width to length or into a partial double-layered repair; the creation of artificial neoligaments; the prevention of urinary retention by avoiding tightness in the bladder neck area; local anesthetic infiltration; and buttressing vaginal tissue during wound healing. A total of 108 patients underwent vaginal surgery on an ambulatory or overnight stay basis, 72 under local anesthesia/midazolam. Minimal postoperative pain and the absence of catheterization reduced hospital stay from a statewide mean of 8 days to 1 day, and return to normal activities from 6 weeks to 7-10 days. Cure rates (18 months) were: uterovaginal prolapse 22/22, infracoccygeal sacropexy 21/23, rectocele 36/38, cystocele/anterior vaginal wall prolapse 21/25. Applied as prototypes to reconstructive vaginal surgery, the operations appear to be as effective as traditional techniques but far less invasive. They have the potential to assist working mothers, the old and infirm, and save the community up to $5,500 per patient. It is hoped that the generic models presented may act as a basis for the future development of ambulatory vaginal surgical techniques. PMID:9657174

    Introduction: Wood’s light lamp is a device that emits ultraviolet (UV) light and is a useful diagnostic tool for dermatologic disorders. The change in the thickness of vaginal mucosa, in vaginal atrophy, causes a change in its colour under Wood’s light. We wanted to assess the feasibility of Wood’s light (WL) as a diagnostic tool for vaginal atrophy. Materials and Methods: The study was conducted at the Department of Obstetrics and Gynaecology from 1 March 2013 to 1 September 2014. We evaluated 45 healthy postmenopausal women with atrophic vaginitis (study group) and 45 healthy, reproductive-aged women as a control group. All patients underwent WL and routine gynaecological examinations for this study. Results: Ninety patients were selected for this study: 45 postmenopausal women suffering atrophic vaginitis symptoms like vaginal dryness, dyspareunia, vulvar pruritus, and signs like pale, smooth, dry, fragile vaginal epithelium, areas of petechiae, and rash, and 45 healthy reproductive-aged women without vaginal atrophy. Thirty-six of the postmenopausal women’s vaginal mucosa appeared pale royal green under WL indicative of vaginal atrophy. Thirty-nine of reproductive-aged women’s (n: 45) vaginal mucosa were not visualized as pale royal green fluorescent images under the WL. Conclusion: Using Wood’s light to diagnose vaginal atrophy is a new use for the old device and may be a reliable, and cheap tool for diagnosing vaginal atrophy. Diagnostic accuracy and cost-effectiveness of Wood’s light will be better optimized in further trials. PMID:25738039

    Bladder rupture following caesarian section is well documented complications. Intraperitoneal bladder rupture following normal vaginal delivery is very rare. Hereby, we present a case report of intraperitoneal bladder rupture presented late following normal vaginal delivery. We report a case of spontaneous intraperitoneal urinary bladder rupture following uneventful outlet forceps delivery in a 22-year-old primi gravid woman with gestational diabetes mellitus and fetal macrosomia who presented with large urinary ascites, anuria and renal failure. Emergent exploratory laparotomy with repair of the intraperitoneal bladder rupture helped to prevent its potential complications. Postpartum patients who undergo episiotomy or perineal repair may land up in unnoticed urinary retention which may rarely terminate in spontaneous urinary bladder rupture. Awareness of its manifestations amongst emergency physician would help to initiate appropriate timely management. PMID:26557563

    Background The composition of the vaginal microbiota is known to be important for health. When infections occur, antimicrobial therapy is often poorly efficacious. Objective and design We used 16S rRNA gene sequencing to characterize changes in the bacterial microbiota following oral antimicrobial and probiotic interventions. Results While the bacterial vaginal profiles of women with vulvovaginal candidiasis were dominated by lactobacilli as in healthy women, and unchanged by therapy, Gardnerella vaginalis, Prevotella, Atopobium, Sneathia, and Megasphaera dominated the vagina of women with bacterial vaginosis (BV), and treatment with tinidazole plus Lactobacillus reuteri RC-14+L. rhamnosus GR-1 resulted in an increased relative abundance of indigenous L. iners or L. crispatus. Conclusions The ability to restore homeostasis provides a rationale for conjoint use of probiotics with antibiotic treatment of BV. PMID:26282697

    Chitosan/alginate complexes were prepared at different polycation/polyanion molar ratios and freeze-dried vaginal inserts were obtained for chlorhexidine digluconate local delivery in genital infections. Complex yield, FT-IR spectra, and TGA thermograms were studied to confirm the interaction between the two polyions. The influence of different complexes on physical handling, morphology, and drug distribution in the samples were evaluated by friability test, scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDS), respectively. In vitro water-uptake, mucoadhesion and release tests were performed as well as microbiological tests toward pathogenic vaginal microorganisms. The results showed that the selection of suitable chitosan/alginate molar ratio and drug loading allowed modulate insert ability to hydrate, adhere to the mucosa, and release chlorhexidine digluconate. The insert containing an excess of alginate was found to be the best performing formulation and showed good antimicrobial activity toward the pathogens Candida albicans and Escherichia coli.

    Little is known about the role that the birth experience plays in brain and cognitive development. Recent research has suggested that birth experience influences the development of the somatosensory cortex, an area involved in spatial attention to sensory information. In this study, we explored whether differences in spatial attention would occur in infants who had different birth experiences, as occurs for caesarean versus vaginal delivery. Three-month-old infants performed either a spatial cueing task or a visual expectation task. We showed that caesarean-delivered infants' stimulus-driven, reflexive attention was slowed relative to vaginally delivered infants', whereas their cognitively driven, voluntary attention was unaffected. Thus, types of birth experience influence at least one form of infants' attention, and possibly any cognitive process that relies on spatial attention. This study also suggests that birth experience influences the initial state of brain functioning and, consequently, should be considered in our understanding of brain development. PMID:26260585

    Approximately 11% of U.S. women undergo surgery for pelvic floor dysfunction, including genital organ prolapse and urinary and fecal incontinence. The major risk factor for developing these conditions is giving vaginal birth. Vaginal birth is a remarkable event about which little is known from a biomechanical perspective. We first review the functional anatomy of the female pelvic floor, the normal loads acting on the pelvic floor in activities of daily living, and the functional capacity of the pelvic floor muscles. Computer models show that the stretch ratio in the pelvic floor muscles can reach an extraordinary 3.26 by the end of the second stage of labor. Magnetic resonance images provide evidence that show that the pelvic floor regions experiencing the most stretch are at the greatest risk for injury, especially in forceps deliveries. A conceptual model suggests how these injuries may lead to the most common form of pelvic organ prolapse, a cystocele. PMID:19591614

    The relationship between vaginal carriage and subsequent neonatal acquisition of Clostridium difficile was investigated. Vaginal carriage of C. difficile was detected in 11% of women attending the Department of Genital Medicine Clinic. C. difficile was isolated from the vagina in 18% of 50 mothers before delivery, and 8% after delivery; 62% of their babies had positive faecal cultures. Eight of nine of the babies whose mothers had positive cultures before delivery became colonised with C. difficile, while 23 of 41 babies whose mothers had negative cultures became colonised. This suggests that both the vagina and the environment may act as sources of neonatal acquisition of C. difficile. Broth enrichment culture proved a more sensitive method for isolating C. difficile from the vagina than direct plate culture and should be used in such investigations. PMID:6748040

    The normal vaginal microbiota is a dynamic system that continually fluctuates under the environmental changes and different physiological conditions. Yeast infections of the vagina are caused by one of the species of fungus called Candida (C.). The study aimed to evaluate the types of mycobiota in women with vulvovaginal candidiasis (VVC) who were performing vaginal douching (VD) or not. Furthermore, it studied the antifungal sensitivity toward different fungi isolated from the vagina. In a cross-sectional study conducted in Assiut University Hospital, Egypt, women with VVC were interviewed regarding relevant history including the habit of VD. Vaginal swabs were obtained and processed by direct microscope and by culture on CHROMagar Candida and other differential media. The types of Candida in women with the habit of VD were compared with those not having this habit. We found that VD habit was practiced by 67.4% of women with VVC, and Candida albicans was the commonest (78.3%) type observed. There was no significant difference in the percentage of non-albicans types between women performing VD (23.6%) and those not reporting this habit (18.9%). Harboring non-albicans types were significantly increased in regular performers of VD compared with those who had this procedure only after sexual intercourse or after the end of menstruation (36.8%,12.5%, and 16.7%, respectively) (P = .048). Thus, vaginal douching does not influence the type of Candida infection involved in VVC. Frequent performance of VD increases the likelihood of having non-albicans types and the resistance to the common antifungal agents. PMID:26129887

    Increasing evidence indicates that abnormal vaginal flora lacking lactobacilli facilitates the acquisition of several sexually transmitted diseases including Chlamydia trachomatis. C. trachomatis, the most common bacterial agent of genital infections worldwide, can progress from the lower to upper reproductive tract and induce severe sequelae. The ability of C. trachomatis to develop into a persistent form has been suggested as key pathogenetic mechanism underlying chronic infections and sequelae. The aim of our study was to investigate the C. trachomatis interaction with vaginal microbiota analyzing the effects of Lactobacillus strains (L. brevis and L. salivarius) on the different phases of C. trachomatis developmental cycle. In addition, the effect of lactobacilli on persistent chlamydial forms induced by HSV-2 coinfection has also been evaluated. Our results demonstrated significant inhibition of C. trachomatis multiplication by vaginal lactobacilli. L. brevis was significantly more effective than L. salivarius (p<0.05) on all the steps of chlamydial infection cycle suggesting that the ability of lactobacilli to protect from infection is strain-dependent. Lactobacilli had an adverse effect on elementary chlamydial bodies (p<0.05), on chlamydial adsorption to epithelial cells (p<0.001) and on intracellular phases of chlamydial replication (p<0.0001). Our study also demonstrated a protective effect of lactobacilli toward persistent C. trachomatis forms induced by HSV-2 coinfection. A significant increase in the production of C. trachomatis infectious progeny was observed in C. trachomatis/HSV-2 coinfection in the presence of L. brevis (p=0.01) despite a significant inhibition of C. trachomatis multiplication (p=0.028). Our data suggest that a healthy vaginal microbiota can reduce the risk of acquiring C. trachomatis infection and counteract the development of persistent chlamydial forms. PMID:24875405

    A sarcoid-like reaction is a development of non-caseating granuloma in patients with underlying malignancy and represents a false positive finding on positron emission tomography/computed tomography (PET/CT). A sarcoid-like reaction is a benign condition; therefore, differentiating a sarcoid-like reaction from cancer recurrence is necessary. Only uterine and ovarian cancer related cases have been reported in the gynecological field and to the best of our knowledge, this is the first case of a sarcoid-like reaction in vaginal cancer. A 59-year-old vaginal cancer patient received concurrent chemoradiotherapy and achieved complete remission. Recurrence of vaginal cancer was suspected because of the elevation of serum squamous cell carcinoma antigen level. PET/CT revealed abnormal uptake at the bilateral mediastinal and hilar lymph nodes. A non-caseating granuloma was detected from the biopsy of the swollen lymph nodes. No evidence of cancer recurrence was observed. A sarcoid-like reaction should be considered when evaluating PET/CT in cancer patients to prevent unnecessary treatments. PMID:26420533

    Vaginal lubricants are widely used by women to help solve intercourse difficulties or as enhancers, but recent reports raise questions about their safety. Twelve commercially available gel products were tested for pH value, pH buffering capacity, osmolality and cytotoxicity relevant to vaginal delivery. Obtained data were analyzed in light of the recent Advisory Note by the World Health Organization (WHO) for personal lubricants to be concomitantly used with condoms. Results showed that most products do not comply with pH and osmolality recommended standards, thus posing a potential hazard. Four products presented values of osmolality around three-times higher than the maximum acceptable limit of 1200 mOsm/kg. In vitro cell testing further identified substantial cytotoxicity even at 1:100 dilutions for three products, contrasting with no significant effect of up to at least a 1:5 dilution of a Universal Placebo gel. However, no direct correlation between these last results and pH or osmolality was found, thus suggesting that the individual toxicity of specific formulation components plays an important role in the outcome of a particular product. Although further assessment is required, these results highlight potential safety issues related to the formulation of commercially available vaginal lubricants. PMID:25247884

    Abstract Objective: To determine induction start time(s) that would maximise daytime deliveries when using prostaglandin vaginal inserts. Methods: Women enrolled into the Phase III trial, EXPEDITE (clinical trial registration: NCT01127581), had labour induced with either a misoprostol or dinoprostone vaginal insert (MVI or DVI). A secondary analysis was conducted to determine the optimal start times for induction by identifying the 12-h period with the highest proportion of deliveries by parity and treatment. Results: Optimal start times for achieving daytime deliveries when using MVI appear to be 19:00 in nulliparae and 23:00 in multiparae. Applying these start times, the median time of onset of active labour would be approximately 08:30 for both parities and the median time of delivery would be the following day at approximately 16:30 for nulliparae and 12:00 (midday) for multiparae. Optimal start times when using DVI appear to be 07:00 for nulliparae and 23:00 for multiparae. Using these start times, the median time of onset of active labour would be the following day at approximately 04:00 and 11:50, and the median time of delivery would be approximately 13:40 and 16:10, respectively. Conclusions: When optimising daytime deliveries, different times to initiate induction of labour may be appropriate depending on parity and the type of retrievable prostaglandin vaginal insert used.

    Introduction: Female urethral stricture is an underdiagnosed and overlooked cause of female bladder outlet obstruction. The possible etiologies may be infection, prior dilation, difficult catheterization with subsequent fibrosis, urethral surgery, trauma, or idiopathic. We present our technique and results of dorsal onlay full thickness vaginal graft urethroplasty for female urethral stricture. Materials and Methods: A retrospective review was performed on 16 female patients with mid-urethral stricture who underwent dorsal onlay vaginal graft urethroplasty from January 2007 to June 2011. Of these, 13 patients had previously undergone multiple Hegar dilatations, three had previous internal urethrotomies. The preoperative work up included detailed voiding history, local examination, uroflowmetry, calibration, and micturating cystourethrogram. Results: All patients had mid-urethral stricture. Mean age was 47.5 years. Mean Qmax improved from 6.2 to 27.6 ml/s. Mean residual volume decreased from 160 to 20 ml. Mean duration of follow-up was 24.5 months (6 months to 3 years). Only one patient required self-calibration for 6 months after which her stricture stabilized. None of the patient was incontinent. Conclusion: Dorsal vaginal onlay graft urethroplasty could be considered as an effective way to treat female urethral stricture. PMID:23956514

    Staphylococcus aureus has been isolated from vaginal fluids of women with toxic shock syndrome (TSS), a multisystem disease with onset usually during menses. A total of 15 vaginal isolates of S. aureus from TSS patients were compared with 18 vaginal isolates from women without TSS. Phenotypic traits which were significantly more frequent in the TSS group of strains than in the non-TSS group were arsenate resistance, proteolysis of hemoglobin, reduced hemolysis of sheep blood in agar medium, and lack of lethality of culture filtrates for chicken embryos and rabbits. In addition, isoelectric focusing of ethanol extracts of culture filtrates showed differences between the two groups in the occurrence of two proteins. All hemolytic and chicken embryo-lethal strains (3 TSS strains and 14 non-TSS strains) produced an extracellular protein with an isoelectric point of 8.6. In contrast, all TSS strains, but only one-half of non-TSS strains, released a protein with an isoelectric point of 7.0 and an apparent subunit molecular weight of 22,000. Images PMID:6456228

    Local delivery to the affected area represents the optimal means by which advantageous pharmacological properties of curcumin may be fully exploited as currently, due to the biopharmaceutical limitations associated with this polyphenol, its full beneficial effects remain limited. Curcumin-containing liposomes coated with bioadhesive polymers of natural and synthetic origin (chitosan and Carbopol) were evaluated in vitro. For these purposes, an in vitro model of vaginal mucus was developed allowing the monitoring of curcumin permeability in the conditions mimicking vaginal environment. The model was optimized by varying the amounts of glycoproteins, as compared to the permeabilities determined through isolated bovine mucus. The strength of bioadhesion was evaluated using the isolated bovine mucosa. Both curcumin solution and non-coated curcumin liposomes served as controls. Bioadhesive polymers enabled significantly higher (p<0.05) curcumin permeability through the artificial and isolated bovine mucus compared to the controls. Polymer coating of liposomes resulted in an increase in their bioadhesiveness. Mucoadhesive liposomes can be considered as potential novel drug delivery systems intended for vaginal administration of curcumin. PMID:24534774

    Dye staining of applicators has been shown to be a reliable and objective method to test vaginal insertion in clinical microbicide trials, but different plastics, dyes and product formulations may impact the accuracy of this method. Reportedly used applicators returned from three clinical trials were stained with 1% Trypan Blue. In a phase 1 study (VivaGel), using gel-filled HTI polypropylene applicators, 1271 (97%) of applicators stained positive. In two phase 1 and 2a studies (LACTIN-V) using linear low-density polyethylene applicators to deliver a dry powder formulation, 57 (95%) and 135 (86%) tested positive, respectively. Dye staining of vaginal applicators is an objective, low cost measure suitable for low resource settings. PMID:22902667

    The HIV/AIDS pandemic continues to be a global health priority, with high rates of new HIV-1 infections persisting in young women. One HIV prevention strategy is topical pre-exposure prophylactics or microbicides, which are applied vaginally or rectally to protect the user from HIV and possibly other sexually transmitted infections. Vaginal microbicide delivery will be the focus of this review. Multiple nonspecific and specific antiretroviral microbicide products have been clinically evaluated, and many are in preclinical development. The events of HIV mucosal transmission and dynamics of the cervicovaginal environment should be considered for successful vaginal microbicide delivery. Beyond conventional vaginal formulations, intravaginal rings, tablets and films are employed as platforms in the hope to increase the likelihood of microbicide use. Furthermore, combining multiple antiretrovirals within a given formulation, combining a microbicide product with a vaginal device and integrating novel drug-delivery strategies within a microbicide product are approaches to successful vaginal-microbicide delivery.

    Until recently, bacterial species that inhabit the human vagina have been primarily studied using organism-centric approaches. Understanding how these bacterial species interact with each other and the host vaginal epithelium is essential for a more complete understanding of vaginal health. Molecular approaches have already led to the identification of uncultivated bacterial taxa associated with bacterial vaginosis. Here, we review recent studies of the vaginal microbiome and discuss how culture-independent approaches, such as applications of next-generation sequencing, are advancing the field and shifting our understanding of how vaginal health is defined. This work may lead to improved diagnostic tools and treatments for women who suffer from, or are at risk for, vaginal imbalances, pregnancy complications, and sexually acquired infections. These approaches may also transform our understanding of how host genetic factors, physiological conditions (e.g., menopause), and environmental exposures (e.g., smoking, antibiotic usage) influence the vaginal microbiome.

    To improve efficiency and prolong protection, modern gynecological preparations frequently incorporate polymeric molecules that add a certain degree of viscosity in order to increase adhesion with vaginal cells and prolong local delivery of active molecules. The aim of this study was to investigate the possibility of visualising the ability of a commercial medicated gynecological gel to bind to and be retained by human vaginal cells. The gel formulation included the essential oils of Thymus vulgaris and Eugenia cariophylla, which contain active molecules such as thymol and eugenol that are known to have useful antibacterial and antimycotic activities. The adherence of different dilutions of the gel to human vaginal cells was visualised by means of Nomarski interference contrast microscopy and scanning electron microscopy using ferric oxide particles and Escherichia coli as inorganic and organic markers, both of which made it possible to visualise the binding of the thin transparent layer of gel and the retaining effect, which was proportional to the degree of dilution.

    The aim of this study was to investigate the period of estrus cycle in aceh cattle, Indonesia, based on vaginal cytology techniques. Four healthy females of aceh cattle with average weight of 250–300 kg, age of 5–7 years, and body condition score of 3-4 were used. All cattle were subjected to ultrasonography analysis for the occurrence of corpus luteum before being synchronized using intramuscular injections of PGF2 alpha 25 mg. A vaginal swab was collected from aceh cattle, stained with Giemsa 10%, and observed microscopically. Period of estrus cycle was predicted from day 1 to day 24 after estrus synchronization was confirmed using ultrasonography analysis at the same day. The result showed that parabasal, intermediary, and superficial epithelium were found in the vaginal swabs collected from proestrus, metestrus, and diestrus aceh cattle. Proportions of these cells in the particular period of estrus cycle were 36.22, 32.62, and 31.16 (proestrus); 21.33, 32.58, and 46.09 (estrus); 40.75, 37.58, and 21.67 (metestrus); and 41.07, 37.38, and 21.67 (diestrus), respectively. In conclusion, dominant proportion of superficial cell that occurred in estrus period might be used as the base for determining optimal time for insemination. PMID:26977335

    In criminal investigations there are some cases in which identifying the presence of vaginal secretions provides crucial evidence in proving sexual assault. However, there are no methods for definitively identifying vaginal secretions. In the present study, we focused on Lactobacillus levels in vaginal secretions and developed a novel identification method for vaginal secretions by relative quantification based on real time PCR. We designed a Lactobacillus conserved region primer pair (LCP) by aligning 16S rRNA gene sequences from major vaginal Lactobacillus species (Lactobacillus crispatus, Lactobacillus gasseri, Lactobacillus iners and Lactobacillus jensenii), and selected the human specific primer pair (HSP) as an endogenous control for relative quantification. As a result, the ΔCt (ΔCt=Ct[LCP]-Ct[HSP]) values of vaginal secretions (11 out of 12 samples) were significantly lower than those of saliva, semen and skin surface samples, and it was possible to discriminate between vaginal secretions and other body fluids. For the one remaining sample, it was confirmed that the predominant species in the microflora was not of the Lactobacillus genus. The ΔCt values in this study were calculated when the total DNA input used from the vaginal secretions was 10pg or more. Additionally, the ΔCt values of samples up to 6-months-old, which were kept at room temperature, remained unchanged. Thus, we concluded in this study that the simple ΔCt method by real time PCR is a useful tool for detecting the presence of vaginal secretions. PMID:24905338

Expert opinion was based on review of the relevant scientific and medical literature. Main Outcome Measure Genitourinary symptoms and treatment of vaginal atrophy from peer-reviewed published literature. Results Typically, a diagnosis of vaginal atrophy is made based on patient-reported symptoms, including genitourinary symptoms, and an examination that reveals signs of the disorder; however, many women are hesitant to report vaginal-related symptoms, primarily because of embarrassment. Conclusions Physicians in various disciplines are encouraged to initiate open discussions about vulvovaginal health with postmenopausal women, including recommended treatment options.

    Pediococcus pentosaceus SB83 is a bacteriocinogenic culture having potential use as a vaginal probiotic. The objective of this study was to evaluate the behaviour of P. pentosaceus SB83 incorporated in a liquid system for eventually formulating a gel for vaginal delivery. The vaginal probiotic incorporated into glycerol was able to survive in simulated vaginal fluid at normal vaginal pH (4.2) and at pH of vaginal infections (5.5 and 6.5). The probiotic can be stored at 4 C for a longer period of time than at room temperature, however, after 13 weeks of storage at low temperature, there was a total loss of viable cells. The probiotic strain incorporated into glycerol showed bacteriocinogenic activity in simulated vaginal fluid, although the antimicrobial activity against Listeria monocytogenes declined during storage. This study showed the behaviour of P. pentosaceus SB83 in glycerol and in simulated vaginal fluid. However, it is necessary to optimise the formulation to produce an actively probiotic vaginal gel.

    Background: Vaginal atrophy is a common complication in menopause which does not improve with time and, if untreated, can affect the quality of life for women. The aim of this study was to compare the effectiveness of the vaginal cream of hyaluronic acid and conjugated estrogen (Premarin) in treatment of vaginal atrophy. Methods: This study was a randomized controlled clinical trial on 56 menopausal women with symptoms of vaginal atrophy; they were randomly allocated to two groups (recipient conjugated estrogen and hyaluronic acid). The severity of each sign of atrophy was evaluated by visual analog signals (VAS) and on the basis of a four point scale. Also to recognize the cellular maturation with pap smear and the maturation degree were calculated according to the formula and scores 0-100. As to the vaginal PH, we used PH marker band, the rate of which was divided into 4 degrees. Data were analyzed using SPSS, version 20, and P≤0.05 was considered as significant. Results: The results of this study showed that the symptoms of vaginal atrophy compared with the baseline level were relieved significantly in both groups. Dryness, itching, maturation index, PH and composite score of the vaginal symptoms were relieved significantly in both groups (P<0.001). Dyspareunia in Premarin (P<0.05) and hyaluronic acid (P<0.001) decreased compared with pre-treatment. Urinary incontinence only showed improvement in the hyaluronic acid group (P<0.05). Improvement in urinary incontinence, dryness, maturation index (P<0.05) and composite score of vaginal symptoms (P<0.001) in the hyaluronic acid group was better than those in the Premarin group. Conclusion: According to the results of the present study, hyaluronic acid and conjugated estrogen improved the symptoms of vaginal atrophy. But hyaluronic acid was more effective and this drug is suggested for those who do not want to or cannot take local hormone treatment. Trial Registration Number: IRCT2013022712644N1 PMID:26793732

    Mucosal cell-mediated immunity (CMI) by CD4+ T cells is postulated to be important for host defence against several vaginal pathogens. In addition to the recognized phenotypic distinctions of resident vaginal T lymphocytes, we recently provided evidence by fluorescence-activated cell sorter (FACS) that murine vaginal CD4+ T lymphocytes, are differentially recognized by two epitope-distinct anti-CD4 antibodies, suggesting that the CD4 protein on vaginal CD4+ cells is atypically expressed. In the present study, we confirm this by FACS and immunohistochemistry under non-denaturing conditions using two additional anti-CD4 antibodies. However, positive immunohistochemical staining of vaginal CD4+ cells under denaturing conditions revealed that the CD4 epitope in question is indeed present within the CD4 protein. Using reverse transcription polymerase chain reaction, amplification of CD3, T-cell receptor-β (TCR-β), and TCR-δ mRNA from lymph node and vaginal tissue, and CD4 mRNA from lymph node tissue was demonstrable. In contrast, amplification of CD4 mRNA from vaginal tissue, vaginal enriched lymphoid cells, or a purified (FACS-sorted) population of vaginal-specific CD4+ cells using two distinct primer sets was not demonstrable. Altogether, our results provide evidence that the CD4 protein on vaginal CD4+ T cells is conformationally distinct compared with its systemic counterpart, either as a result of a unique CD4 mRNA sequence or from a stable interaction of soluble CD4 with the surface of vaginal T cells.

    Vaginal rapidly disintegrating tablets (RDTs) containing tenofovir (TFV) or TFV and emtricitabine (FTC) were evaluated for safety and pharmacokinetics in pigtailed macaques. Two separate animal groups (n = 4) received TFV (10 mg) or TFV-FTC (10 mg each) RDTs, administered near the cervix. A third group (n = 4) received 1 ml TFV gel. Blood plasma, vaginal tissue biopsy specimens, and vaginal fluids were collected before and after product application at 0, 0.5, 1, 4, and 24 h. A disintegration time of <30 min following vaginal application of the RDTs was noted, with negligible effects on local inflammatory cytokines, vaginal pH, and microflora. TFV pharmacokinetics were generally similar for both RDTs and gel, with peak median concentrations in vaginal tissues and vaginal secretions being on the order of 104 to 105 ng/g (147 to 571 μM) and 106 ng/g (12 to 34 mM), respectively, at 1 to 4 h postdose. At 24 h, however, TFV vaginal tissue levels were more sustained after RDT dosing, with median TFV concentrations being approximately 1 log higher than those with gel dosing. FTC pharmacokinetics after combination RDT dosing were similar to those of TFV, with peak median vaginal tissue and fluid levels being on the order of 104 ng/g (374 μM) and 106 ng/g (32 mM), respectively, at 1 h postdose with levels in fluid remaining high at 24 h. RDTs are a promising alternative vaginal dosage form, delivering TFV and/or FTC at levels that would be considered inhibitory to simian-human immunodeficiency virus in the macaque vaginal microenvironment over a 24-h period.

    Background Daily pre-exposure prophylaxis (PrEP) with Truvada (a combination of emtricitabine (FTC) and tenofovir (TFV) disoproxil fumarate (TDF)) is a novel HIV prevention strategy recently found to prevent HIV transmission in men who have sex with men and heterosexual couples. We previously showed that a coitally-dependent Truvada regimen protected macaques against rectal SHIV transmission. Here we examined FTC and tenofovir TFV exposure in vaginal tissues after oral dosing and assessed if peri-coital Truvada also protects macaques against vaginal SHIV infection. Methods The pharmacokinetic profile of emtricitabine (FTC) and tenofovir (TFV) was evaluated at first dose. FTC and TFV levels were measured in blood plasma, rectal, and vaginal secretions. Intracellular concentrations of FTC-triphosphate (FTC-TP) and TFV-diphosphate (TFV-DP) were measured in PBMCs, rectal tissues, and vaginal tissues. Efficacy of Truvada in preventing vaginal SHIV infection was assessed using a repeat-exposure vaginal SHIV transmission model consisting of weekly exposures to low doses of SHIV162p3. Six pigtail macaques with normal menstrual cycles received Truvada 24 h before and 2 h after each weekly virus exposure and six received placebo. Infection was monitored by serology and PCR amplification of SHIV RNA and DNA. Results As in humans, the concentration of FTC was higher than the concentration of TFV in vaginal secretions. Also as in humans, TFV levels in vaginal secretions were lower than in rectal secretions. Intracellular TFV-DP concentrations were also lower in vaginal tissues than in rectal tissues. Despite the low vaginal TFV exposure, all six treated macaques were protected from infection after 18 exposures or 4 full menstrual cycles. In contrast, all 6 control animals were infected. Conclusions We modeled a peri-coital regimen with two doses of Truvada and showed that it fully protected macaques from repeated SHIV exposures. Our results open the possibility for simplified PrEP regimens to prevent vaginal HIV transmission in women. PMID:23226529

  6. Multicompartmental Pharmacokinetic Model of Tenofovir Delivery by a Vaginal Gel

    Background Trials of a vaginal Tenofovir gel for pre-exposure prophylaxis (PrEP) for HIV have given conflicting results. Knowledge of concentrations of Tenofovir and its active form Tenofovir diphosphate, at putative sites of anti-HIV functioning, is central to understanding trial outcomes and design of products and dosage regimens. Topical Tenofovir delivery to the vaginal environment is complex, multivariate and non-linear; determinants relate to drug, vehicle, dosage regimen, and environment. Experimental PK methods cannot yield mechanistic understanding of this process, and have uncontrolled variability in drug sampling. Mechanistic modeling of the process could help delineate its determinants, and be a tool in design and interpretation of products and trials. Methods and Findings We created a four-compartment mass transport model for Tenofovir delivery by a gel: gel, epithelium, stroma, blood. Transport was diffusion-driven in vaginal compartments; blood concentration was time-varying but homogeneous. Parameters for the model derived from in vitro and in vivo PK data, to which model predictions gave good agreement. Steep concentration gradients occurred in stroma ?8 hours after gel release. Increasing epithelial thickness delayed initial TFV delivery to stroma and its decline: tmax increased but AUC at 24 hours was not significantly altered. At 24 and 48 hours, stromal concentrations were 6.3% and 0.2% of Cmax. Concentrations in simulated biopsies overestimated stromal concentrations, as much as ?5X, depending upon time of sampling, biopsy thickness and epithelial thickness. Conclusions There was reasonably good agreement of model predictions with clinical PK data. Conversion of TFV to TFV-DP was not included, but PK data suggest a linear relationship between them. Thus contrasts predicted by this model can inform design of gels and dosage regimens in clinical trials, and interpretation of PK data. This mass transport based approach can be extended to TFV conversion to TFV-DP, and to other drugs and dosage forms. PMID:24040241

    The aim of this study was to demonstrate the feasibility of a total hysterectomy performed entirely by transvaginal natural orifice transluminal endoscopic surgery (vNOTES). Conventional, reusable laparoscopic instruments were used, inserted through an inexpensive, self-constructed single-port device. Ten total vaginal NOTES hysterectomies (TVNHs) were performed by a single surgeon. The self-constructed single-port device was made by assembling a surgical glove, a wound protector or modified laryngeal mask airway, 1 reusable 10-mm trocar, and 4 reusable 5-mm trocars. This gloveport was inserted into the vagina to create a pneumovagina. The conventional steps of a vaginal hysterectomy were followed, but performed endoscopically with standard reusable endoscopic instruments. The patient and perioperative data were analyzed. No conversion to standard laparoscopy or laparotomy was necessary in any of the 10 patients who underwent a TVNH. Mean operation time was 97 min (range: 60-120); mean drop in hemoglobin level was 1.5 g/dL (range: 0.5-2.4). There were no operative complications, and postoperative pain scores were very low. This first report on a small number of patients demonstrates that TVNH is possible. By incorporating the advantages of endoscopic surgery, TVNH broadens the indications for vaginal hysterectomy and helps overcome its limitations. At the same time, the NOTES approach avoids abdominal wall wounds and trocar-related complications. TVNH is feasible, even when performed with reusable, conventional laparoscopic instruments. This frugally innovative technique also enables surgeons to perform hysterectomies by vNOTES in low resource settings. PMID:26009278

    The antimycotic imidazole derivative clotrimazole is employed locally for the treatment of genitourinary tract mycotic infections and is formulated as creams, foams, tablets, gels, irrigations, or pessaries. In this study, a new dosage form was developed by including bioadhesive polymers (polycarbophyl, hydroxypropylmethylcellulose, and hyaluronic sodium salt) into pessaries made of semisynthetic solid triglycerides. These polymers hold the delivery systems in the vaginal tract for a few days without any toxic effects or important physiological modifications, prolonging the permanence of the drug on the vaginal mucosa. Technological controls (compatibility with differential scanning calorimetry [DSC] studies, particle size analysis, and liquefaction time test) and biopharmaceutics studies for the evaluation of the release of the drug from the dosage form and of the bioadhesive properties were carried out. Moreover, a new test for the evaluation of the permanence of the drug in a simulated application site was developed from a modification of the Satnikar and Fantelli method for the evaluation of the liquefaction time of rectal suppositories. This test simulates the physiological vaginal condition and verifies the efficiency of the polymers in prolonging the permanence of the dosage form in the location where it is applied. The technological controls demonstrated that the presence of the polymers did not have an influence on the characteristics of the pessaries. On the other hand, there was an improvement in adhesivity of the pessaries in the in vitro adhesion test and prolonging of the liquefaction time in the liquefaction time test in the presence of mucoadhesive polymers, which increased with increasing polymer concentration. The presence of the mucoadhesive had a large influence on the permanence of the drug in the simulated application site because it modified the distribution of the drug along the simulated application site. In conclusion, the developed new formulations showed good technological and adhesion properties and the capacity of hold the dosage form in the target site. Among the employed bioadhesive polymers, the best behavior in the performed test was by polycarbophyl at its maximum concentration. PMID:11548861

    Objective Cesarean rates in recent decades have been increasing and a number of studies have shown that cesarean increases maternal morbidities. The aim of this study is to compare the quality of life after cesarean and vaginal delivery. Methods This prospective study was carried out on 356 pregnant women visiting urban health centers in Shahroud City, Northeast Iran, in 2011. The subjects completed the quality of life questionnaire in the third trimester of pregnancy and at 8 weeks postpartum. Results In primiparas, the mean global QOL scores for the cesarean and vaginal delivery groups were 67.6512.7 and 72.1211.8, respectively. Also, the scores for the physical, psychological and social domains of QOL as well as the global score of QOL were higher in the vaginal delivery group than the cesarean group (p<0.05). In the case of primiparas, multiple regression analysis revealed that after adjusting for education, desirability of pregnancy and the General Health Questionnaire score, the delivery type remained as a predictor of the scores for the physical (R2=1.7%; B=-3.826; p=0.031; CI [-7.301, -.350]) and social (R2=2.5%; B=-5.708; p=0.017; CI [-10.392, -1.023]) domains of QOL and the global QOL score (R2=2.6%; B=-4.065; p=0.006; CI [-6.964, -1.164]). While multiparas, there was no relationship between QOL and type of delivery. Conclusion In this sample of low-risk women, cesarean negatively affected the QOL of primiparas. More studies with larger sample sizes should be conducted to examine the effects of cesarean on QOL in both primiparas and multiparas within a shorter period after delivery. PMID:23904916

    Objective To compare the impact of the prototype prolapse mesh Gynemesh PS to that of two new generation lower stiffness meshes, UltraPro and SmartMesh, on vaginal morphology and structural composition. Design A mechanistic study employing a non-human primate (NHP) model. Setting Magee-Womens Research Institute at the University of Pittsburgh. Population Parous rhesus macaques, with similar age, weight, parity and POP-Q scores. Methods Following IACUC approval, 50 rhesus macaques were implanted with Gynemesh PS (n=12), UltraPro with its blue line perpendicular to the longitudinal axis of vagina (n=10), UltraPro with its blue line parallel to the longitudinal axis of vagina (n=8) and SmartMesh (n=8) via sacrocolpopexy following hysterectomy. Sham operated animals (n=12) served as controls. Main Outcome Measures The mesh-vagina complex (MVC) was removed after 12 weeks and analyzed for histomorphology, in situ cell apoptosis, total collagen, elastin, glycosaminoglycan content and total collagenase activity. Appropriate statistics and correlation analyses were performed accordingly. Results Relative to sham and the two lower stiffness meshes, Gynemesh PS had the greatest negative impact on vaginal histomorphology and composition. Compared to sham, implantation with Gynemesh PS caused substantial thinning of the smooth muscle layer (1557 ± 499μm vs 866 ± 210 μm, P=0.02), increased apoptosis particularly in the area of the mesh fibers (P=0.01), decreased collagen and elastin content (20% (P=0.03) and 43% (P=0.02), respectively) and increased total collagenase activity (135% (P=0.01)). GAG (glycosaminoglycan), a marker of tissue injury, was the highest with Gynemesh PS compared to sham and other meshes (P=0.01). Conclusion Mesh implantation with the stiffer mesh Gynemesh PS induced a maladaptive remodeling response consistent with vaginal degeneration. PMID:23240802

    We present an institutional experience on the clinical implementation of magnetic resonance (MR)-guided vaginal brachytherapy using commercially available solid applicator models. To test the fidelity of solid applicator models to digitize vaginal cylinder applicators, three datasets were evaluated. The first included 15patients who were simulated with CT alone. Next, a water phantom was used to evaluate vaginal cylinders ranging from 20 to 35 mm in diameter with CT and MR. Finally, three patients undergoing HDR brachytherapy with vaginal cylinders that were simulated with both CT and MR were evaluated. In these assessments, the solid applicator models were aligned based on the outline of the applicators on the corresponding volumetric image, and deviations between the central source positions defined based on X-ray markers (on CT) and solid applicator models (on CT and MR), and the percent dose difference between select reference points were calculated. The mean central source deviation defined based on X-ray markers (on CT) and solid applicator models (on CT and MR) for the 15-patient cohort, the phantom, and the 3-patient cohort is 0.6 mm, 0.6 mm, and 1.2 mm, respectively. The average absolute percent dose difference for the bladder, rectum, prescription, and inferior reference points were 2.2%, 2.3%, 2.2%, and 2.4%, respectively, for the 15 patient cohort. For the phantom study, the average, absolute percent dose difference for the prescription and inferior reference points are 2.0% and 2.1% for the CT, 2.3% and 2.2% for the T1W, and 2.8% and 3.0% for the T2W images. For the three patient cohort, the average absolute percent dose difference for the bladder, rectum, prescription, and inferior reference points are 2.9%, 2.6%, 3.0%, and 4.2% for the CT, 6.5%, 1.6%, 2.5%, and 4.7% for the T1W, and 6.0%, 7.4%, 2.6, and 2.0% for the T2W images. Based on the current study, aligning the applicator model to MR images provides a practical, efficient approach to perform MR-based brachytherapy planning. PMID:26699556

    Vaginal discharge is a frequent presenting complaint in an office practice. The authors of this article review the most common causes of this condition, namely Candidiasis, Trichimoniasis, and Bacterial Vaginosis (Gardnerella), as well as the more serious causes, namely gonorrhea, chlamydia, and Herpes simplex. Symptoms and physical signs are generally insufficient to distinguish specific etiologic agents and, as treatment for each is different, diagnostic examination of smears in the office is critical to the management of these patients. A clinical approach and method of office diagnosis is described. PMID:21263805

    Cesarean deliveries represent almost one third of US births. Given that repeat cesarean is the most common single indication for cesarean, trial of labor after cesarean (TOLAC) with subsequent vaginal birth after cesarean (VBAC) is an important mechanism to reduce the overall cesarean rate. The 2010 National Institutes of Health Conference found that one of the biggest barriers to VBAC is the lack of patient access to TOLAC. Many women who currently deliver by repeat cesarean would be candidates for a TOLAC. This manuscript will summarize the evidence on VBAC to help clinicians identify candidates, provide evidence-based counseling, and guide management of TOLAC. PMID:25811124

    Sildenafil is an active substance that has already been approved by FDA for human use. It is known to be an active compound for the treatment of sexual dysfunction in men. Some encouraging results have been published concerning the treatment of infertility with sildenafil in women, but there is no pharmaceutical preparation available. Therefore, various formulations were prepared and the most suitable sildenafil release was found to be with the sildenafil-containing suppositories prepared using Eudragit RS100 and Witepsol H15. The vaginal insert with EVAC 210 polymer containing sildenafil has also provided sildenafil release for a longer period. PMID:18446572

    Problem Vaginal microbicides represent a promising approach for preventing heterosexual HIV transmission. However, preclinical evaluation should be conducted to ensure that microbicides will be safe for human cells and healthy microflora of the female reproductive tract. One microbicide candidate, RC-101, has been effective and well-tolerated in preliminary cell culture and macaque models. However, the effect of RC-101 on primary vaginal tissues and resident vaginal microflora requires further evaluation. Method of Study We treated primary vaginal tissues and vaginal bacteria, both pathogenic and commensal, with RC-101 to investigate effects of this microbicide. Results RC-101 was well-tolerated by host tissues, and also by commensal vaginal bacteria. Simultaneously, pathogenic vaginal bacteria, which are known to increase susceptibility to HIV acquisition, were inhibited by RC-101. Conclusions By establishing vaginal microflora, the specific antibacterial activity of RC-101 may provide a dual mechanism of HIV protection. These findings support advancement of RC-101 to clinical trials. PMID:23167830

    Mucosal epithelia use osmotic gradients for fluid absorption and secretion. We hypothesized that administration of hypotonic solutions would induce fluid uptake that could be advantageous for rapidly delivering drugs through mucus to the vaginal epithelium. We found that hypotonic formulations markedly increased the rate at which small molecule drugs and muco-inert nanoparticles (mucus-penetrating particles, or MPP), but not conventional mucoadhesive nanparticles (CP), reached the vaginal epithelial surface in vivo in mice. Additionally, hypotonic formulations greatly enhanced drug and MPP delivery to the entire epithelial surface, including deep into the vaginal folds (rugae) that drugs or MPP in isotonic formulations failed to reach efficiently. However, hypotonic formulations caused unencapsulated free drugs to be drawn through the epithelium, reducing vaginal retention. In contrast, hypotonic formulations caused MPP to accumulate rapidly and uniformly on vaginal surfaces, ideally positioned for localized sustained drug delivery. Using a mouse model of vaginal genital herpes (HSV-2) infection, we found that hypotonic delivery of free drug led to improved immediate protection, but diminished longer-term protection. In contrast, as we previously demonstrated, hypotonic delivery of drug via MPP led to better long-term retention and protection in the vagina. Importantly, we demonstrate that slightly hypotonic formulations provided rapid and uniform delivery of MPP to the entire vaginal surface, thus enabling formulations with minimal risk of epithelial toxicity. Hypotonic formulations for vaginal drug delivery via MPP may significantly improve prevention and treatment of reproductive tract diseases and disorders. PMID:23769419

    Aim of this article is to examine if we could identify factors that predict cesarean section and instrumental vaginal delivery in women who had a successful external cephalic version. We used data from a previous randomized trial among 25 hospitals and their referring midwife practices in the Netherlands. With the data of this trial, we performed a cohort study among women attempting vaginal delivery after successful ECV. We evaluated whether maternal age, gestational age, parity, time interval between ECV and delivery, birth weight, neonatal gender, and induction of labor were predictive for a vaginal delivery on one hand or a CS or instrumental vaginal delivery on the other hand. Unadjusted and adjusted odds ratios were calculated with univariate and multivariate logistic regression analysis. Among 301 women who attempted vaginal delivery after a successful external cephalic version attempt, the cesarean section rate was 13% and the instrumental vaginal delivery rate 6%, resulting in a combined instrumental delivery rate of 19%. Nulliparity increased the risk of cesarean section (OR 2.7 (95% CI 1.2-6.1)) and instrumental delivery (OR 4.2 (95% CI 2.1-8.6)). Maternal age, gestational age at delivery, time interval between external cephalic version and delivery, birth weight and neonatal gender did not contribute to the prediction of failed spontaneous vaginal delivery. In our cohort of 301 women with a successful external cephalic version, nulliparity was the only one of seven factors that predicted the risk for cesarean section and instrumental vaginal delivery.

    Vaginal probiotics containing lactic acid bacteria with activity towards pathogenic microorganisms that cause urogenital tract infections have been proposed as a valid strategy for their prophylaxis and therapy. A murine experimental model was set up to evaluate the colonization capability of beneficial human lactobacilli and their effects on the mouse vaginal mucosa and innate immune cells. Five Lactobacillus strains were intravaginally inoculated into previously estrogenized BALB/c mice. The significance of the effects observed in the vaginal tract was determined by analysis of variance using the general linear model. The numbers of viable vaginal lactobacilli were significantly higher at proestrous-estrous than those at the metaestrous-diestrous phase and decreased markedly on the days after inoculation. Lactobacilli inoculation did not cause cytological or histological modifications of the murine vaginal tract. Moreover, the intravaginal administration of Lactobacillus salivarius CRL (Centro de Referencia para Lactobacilos culture collection) 1328 and Lactobacillus gasseri CRL 1263 did not affect the amounts of granulocytes and macrophages present in vaginal washings. In conclusion, the results demonstrate that vaginal lactobacilli did not produce adverse effects on the murine vaginal tract. Therefore, they could be proposed as safe probiotic candidates to promote a balanced microbiota in the urogenital tract. PMID:22638932

    Objective: The objective of the present investigation was formulation, optimization and characterization of mucoadhesive film of clotrimazole (CT) which is patient-convenient and provides an effective alternative for the treatment of vaginal candidiasis. CT is an antimycotic drug applied locally for the treatment of vaginal candidiasis. Materials and Methods: Mucoadhesive vaginal films were prepared by solvent casting technique using hydroxyl propylcellulose and sodium alginate as polymers. Propylene glycol and polyethylene glycol-400 were evaluated as plasticizers. The mucoadhesive vaginal films were evaluated for percentage elongation, tensile strength, folding endurance, drug content, in vitro disintegration time, in vitro dissolution study, swelling index, bioadhesive strength, and diffusion study. Results: Among various permeation enhancers used, isopropyl myristate was found to be suitable. To evaluate the role of the concentration of permeation enhancer and concentration of polymers in the optimization of mucoadhesive vaginal film, 32 full factorial design was employed. Optimized batch showed in vitro disintegration time, 18 min; drug content, 99.83%; and tensile strength, 502.1 g/mm2. In vitro diffusion study showed that 77% drug diffusion occurred in 6 h. This batch was further evaluated by scanning electron microscopy indicating uniformity of the film. In vitro Lactobacillus inhibition and in vitro antifungal activity of optimized batch showed an inhibitory effect against Candida albicans and no effect on Lactobacillus, which is a normal component of vaginal flora. Conclusion: Mucoadhesive vaginal film of CT is an effective dosage form for the treatment of vaginal candidiasis. PMID:27014619

    The human vaginal microbiome plays a critical but poorly defined role in reproductive health. Vaginal microbiome alterations are associated with increased susceptibility to sexually-transmitted infections (STI) possibly due to related changes in innate defense responses from epithelial cells. Study of the impact of commensal bacteria on the vaginal mucosal surface has been hindered by current vaginal epithelial cell (VEC) culture systems that lack an appropriate interface between the apical surface of stratified squamous epithelium and the air-filled vaginal lumen. Therefore we developed a reproducible multilayer VEC culture system with an apical (luminal) air-interface that supported colonization with selected commensal bacteria. Multilayer VEC developed tight-junctions and other hallmarks of the vaginal mucosa including predictable proinflammatory cytokine secretion following TLR stimulation. Colonization of multilayers by common vaginal commensals including Lactobacillus crispatus, L. jensenii, and L. rhamnosus led to intimate associations with the VEC exclusively on the apical surface. Vaginal commensals did not trigger cytokine secretion but Staphylococcus epidermidis, a skin commensal, was inflammatory. Lactobacilli reduced cytokine secretion in an isolate-specific fashion following TLR stimulation. This tempering of inflammation offers a potential explanation for increased susceptibility to STI in the absence of common commensals and has implications for testing of potential STI preventatives.

    We reported a rare case of recurrent vulvovaginal candidiasis (RVVC) in this study. Through dynamic evaluation of the vaginal micro-ecosystem, we found that only depuratory degree, spores, blastospores, and hyphae were specific indicators and the "barometer" of RVVC development. Therefore, an understanding of vaginal micro-ecological changes can help clinicians to improve the treatment of patients with RVVC. PMID:25867410

    The main objective of this work was to develop antifungal matrix tablet for vaginal applications using mucoadhesive thiolated polymer. Econazole nitrate (EN) and miconazole nitrate (MN) were used as antifungal drugs to prepare the vaginal tablet formulations. Thiolated poly(acrylic acid)-cysteine (PAA-Cys) conjugate was synthesized by the covalent attachment of L-cysteine to PAA with the formation of amide bonds between the primary amino group of L-cysteine and the carboxylic acid group of the polymer. Vaginal mucoadhesive matrix tablets were prepared by direct compression technique. The investigation focused on the influence of modified polymer on water uptake behavior, mucoadhesive property and release rate of drug. Thiolated polymer increased the water uptake ratio and mucoadhesive property of the formulations. A new simple dissolution technique was developed to simulate the vaginal environment for the evaluation of release behavior of vaginal tablets. In this technique, daily production amount and rate of the vaginal fluid was used without any rotational movement. The drug release was found to be slower from PAA-Cys compared to that from PAA formulations. The similarity study results confirmed that the difference in particle size of EN and MN did not affect their release profile. The release process was described by plotting the fraction released drug versus time and n fitting data to the simple exponential model: M(t)/M(?)=kt(n). The release kinetics were determined as Super Case II for all the formulations prepared with PAA or PAA-Cys. According to these results the mucoadhesive vaginal tablet formulations prepared with PAA-Cys represent good example for delivery systems which prolong the residence time of drugs at the vaginal mucosal surface.

  8. Vaginally Administered Danazol: An Overlooked Option in the Treatment of Rectovaginal Endometriosis?

    PubMed

    Godin, Richard; Marcoux, Violaine

    2015-12-01

    Danazol has been used in the treatment of endometriosis and heavy menstrual bleeding for more than 40 years. This medication has both central antigonadotropic actions and direct atrophic effects on endometriotic tissue. Although it demonstrates a high-efficacy profile, the associated side effects have resulted in limited usage. Vaginal administration of the drug may prove favourable specifically in rectovaginal endometriosis. This targeted mode of delivery is associated with a significant reduction in both pain symptoms and nodule size. The relative persistence of these therapeutic benefits is likely related to the direct tissue effects after absorption through the vaginal mucosa. Vaginal administration would also limit systemic propagation of danazol and thus should minimize androgenic side effects. Use of vaginal danazol also improves heavy menstrual bleeding and may even restore fertility in some patients. In this review we provide a critical analysis of the existing literature on the use of vaginal danazol. PMID:26637082

    Colpohysterectomy is sometimes associated with a large upper colpectomy resulting in a shortened vagina, potentially impacting sexual function. We report on a preliminary experience of a laparoscopic colpoplasty to restore a normal vaginal length. Patients with shortened vaginas after a laparoscopic colpohysterectomy were considered for a laparoscopic modified Davydov's procedure to create a new vaginal vault using the peritoneum of the rectum and bladder. From 2010 to 2014, 8 patients were offered this procedure, after informed preoperative consent. Indications were 2 extensive recurrent vaginal intraepithelial neoplasias grade 3 and 6 radical hysterectomies for cervical cancer. Mean vaginal length before surgery was 3.8cm (standard deviation, 1.6). Median operative time was 50minutes (range, 45-90). Blood loss was minimal (50-100mL). No perioperative complications occurred. Median vaginal length at discharge was 11.3cm (range, 9-13). Sexual intercourse could be resumed around 10weeks after surgery. At a median follow-up of 33.8months (range, 2.4-51.3), 6 patients remained sexually active but 2 had stopped. Although this experience is small, this laparoscopic modified Davydov's procedure seems to be an effective procedure, adaptable to each patient's anatomy. If the initial postoperative regular self-dilatation is carefully observed, vaginal patency is durably restored and enables normal sexual function. PMID:26299773

    Human papillomavirus (HPV) infection is in the vast majority of patients accountable for the development of vulvar, cervical and vaginal intraepithelial neoplasia (VIN, CIN, VAIN); precursors of vulvar, cervical and vaginal cancers. The currently preferred treatment modality for high grade VIN, CIN and VAIN is surgical excision. Nevertheless surgical treatment is associated with adverse pregnancy outcomes and recurrence is not uncommon. The aim of this review is to present evidence on the efficacy, safety and tolerability of imiquimod (an immune response modifier) in HPV-related VIN, CIN and VAIN. A search for papers on the use of imiquimod in VIN, CIN and VAIN was performed in the MEDLINE, EMBASE and Cochrane library databases. Data was extracted and reviewed. Twenty-one articles met the inclusion criteria and were analyzed; 16 on VIN, 3 on CIN and 2 on VAIN. Complete response rates in VIN ranged from 5 to 88%. Although minor adverse effects were frequently reported, treatment with imiquimod was well tolerated in most patients. Studies on imiquimod treatment of CIN and VAIN are limited and lack uniformly defined endpoints. The available evidence however, shows encouraging effect. Complete response rates for CIN 2-3 and VAIN 1-3 ranged from 67 to 75% and 57 to 86% respectively. More randomized controlled trials on the use of imiquimod in CIN, VAIN and VIN with extended follow-up are necessary to determine the attributive therapeutic value in these patients. PMID:26335596

    In this study, a bioadhesive dosage form of clotrimazole was designed using a combination of bioadhesive polymers Carbopol 934P, sodium carboxymethyl cellulose and sodium alginate in different ratios. The bioadhesive strength was evaluated by measuring the force required to detach the tablets from porcine vaginal mucosal membrane. The strong interaction between polymer and mucus lining of the tissue helps increase the contact time and permits localization of activity. Carbopol 934P showed maximum bioadhesion and required maximum force for detachment; the force required for detachment was directly proportional to its content. The formulations were tested for their swelling behavior using the agar gel plate method. The swelling index was a function of the concentration of the hydrophilic polymer and the formulations containing Carbopol 934P and sodium carboxymethyl cellulose were found to swell to a greater extent than those containing Carbopol and sodium alginate. In vitro release studies showed that the batch consisting of 2:1 ratio of Carbopol 934P/sodium alginate (batch C3) released clotrimazole over 24 h. The similarity factor showed that the dissolution profiles of fresh and aged tablets were similar, suggesting good stability of vaginal tablets prepared using a combination of Carbopol 934P and sodium alginate.

    Bacteroides fragilis is an anaerobic bacterial species that is involved in gynecological infections and pathology. The incidence of vaginal carriage is largely unknown, and in order to study this, 120 pregnant women attending a general hospital for delivery were examined. Cultures were positive for eight of these women (6.6%). Interestingly, potential clonal relatedness could be demonstrated among several of the nonenterotoxigenic B. fragilis strains. Among the strains, only one produced metalloprotease enterotoxin. The presence of the gene for the metalloprotease, giving rise to the pathogenic effect on cultured eukaryotic HT29/C1 cells, was confirmed by a newly designed specific PCR assay. The enterotoxigenic B. fragilis (ETBF) strain was analyzed with the help of arbitrarily primed PCR (AP-PCR) and PCR-mediated ribotyping. The ETBF strain was shown to be genetically different compared to several other strains obtained from diverse sources. Our data indicate a relatively high vaginal B. fragilis carriage rate among pregnant women in Warsaw, Poland. Although neither ETBF nor B. fragilis colonization presented a clinical problem, the possible genetic relatedness among the colonizing B. fragilis strains indicates the need for additional research in the field of ETBF transmission and molecular epidemiology.

    Pelvic organ prolapse is highly prevalent, and negatively affects a woman’s quality of life. Women with bothersome prolapse may be offered pessary management or may choose to undergo corrective surgery. In choosing the most appropriate surgical procedure, there are many factors to consider. These may include the location(s) of anatomic defects, the severity of prolapse symptoms, the activity level of the woman, and concerns regarding the durability of the repair. In many instances, women and their surgeons are challenged to weigh the risks and benefits of native tissue versus mesh-augmented repairs. Though mesh-augmented repairs may offer better durability, they are also associated with unique complications, such as mesh erosion. Furthermore, newer surgical techniques of mesh placement via abdominal or vaginal routes may result in different outcomes compared to traditional techniques. Biologic grafts may also be considered to improve durability of a surgical repair, while avoiding potential complications of synthetic mesh. In this article, we review many of the clinical challenges that gynecologic surgeons face in the surgical management of vaginal prolapse. Furthermore, we review data that can help guide decision making when treating women with pelvic organ prolapse. PMID:24474848

    Male and female sexual dysfunctions encompass biological, psychological and interpersonal aspects. Premature ejaculation (PE) and female vaginal penetration difficulties (VPD) are problems that may concurrently impair the couple's sexual relationship. We have studied the correlation between PE and VPD in the female partner, in a cross-sectional study of 125 heterosexual couples (male age 35.01±10.63; female age 32.36±10.07). VPD included tampon insertion, gynecological examination, inserting self-finger or partner-finger and penile-vaginal intercourse. Female sexual function index (FSFI) and a validated PE questionnaire were used to measure the female sexual function and PE in their male partners. We found that female partners of men with anteportal ejaculation were found to experience significantly more VPDs, especially with regard to difficulties in penile penetration and tampon use. The intensity of pain in VPD was higher in females whose male partners presented anteportal ejaculation. No significant correlation was found between total male PE score and the total FSFI or separate domains of female sexual function. The results suggest that female VPD and male anteportal ejaculation are interrelated. Such severe couple sexual problems should be addressed in parallel. Further research is required to study the causation of PE and VPD. PMID:25716748

    Objectives. To compare the efficacy and safety of intravaginal misoprostol with transcervical Foley catheter for labour induction. Material and Methods. One hundred and four women with term gestation, with Bishop score < 4, and with various indications for labour induction were randomly divided into two groups. In Group I, 25??g of misoprostol tablet was placed intravaginally, 4 hourly up to maximum 6 doses. In Group II, Foley catheter 16F was placed through the internal os of the cervix under aseptic condition and then inflated with 50 cc of sterile saline. Statistical analysis was done using SPSS software. Results. The induction to delivery interval was 14.03 7.61 hours versus 18.40 8.02 hours (p < 0.01). The rate of vaginal delivery was 76.7% versus 56.8% in misoprostol and transcervical Foley catheter group, respectively. Uterine hyperstimulation was more common with misoprostol. Neonatal outcome was similar in both the groups. Conclusion. Intravaginal misoprostol is associated with a shorter induction to delivery interval as compared to Foley's catheter and it increases the rate of vaginal delivery in cases of unripe cervix at term. Transcervical Foley catheter is associated with a lower incidence of uterine hyperstimulation during labour. PMID:26557725

    We examined vaginal deliveries of twins to identify factors most strongly associated with the increased risk of postpartum hemorrhage (estimated blood loss > or = 1,000 mL). We reviewed the obstetric records of all 171 twin vaginal deliveries at Japanese Red Cross Katsushika Maternity Hospital from January 2002 through August 2006. Of these deliveries, 41 (24%) were complicated by postopartum hemorrhage. Postpartum hemorrhage was significantly more likely in cases with gestational age > or = 39 weeks (odds ratio [OR], 3.47; 95% confidence interval [CI], 1.65-7.28), a combined birth weight of more than 5,500 g (OR, 2.53; 95% CI, 1.00-6.45), induction of labor (OR, 2.87; 95% CI, 1.38-5.98), oxytocin administration during labor (OR, 2.86; 95% CI, 1.27-6.48), or a duration of labor > or = 24 hours (OR, 2.55; 95% CI, 1.15-5.62). Postpartum hemorrhage is a frequent complication in twin pregnancies. Therefore, special attention should be given after birth to patients with induction of labor or intervened delivery especially at > or = 39 weeks gestation. PMID:18084135

    Candida albicans is responsible for the majority of cases of vulvovaginal candidiasis (VVC), an infection which occurs mainly during the luteal phase of the menstrual cycle or during the pregnancy, when levels of progesterone are elevated. One of the most important candidal virulence factors is the ability to adhere to host surfaces and form biofilms. The aim of this study was to determine the influence of progesterone on C. albicans virulence, namely biofilm formation and colonisation/invasion of a reconstituted human vaginal epithelium (RHVE). Biofilm formation on the RHVE was evaluated by enumeration of culturable cells, total mass quantification and scanning electron microscopy. The capacity of C. albicans strains to invade and colonise the tissue was examined by fluorescence microscopy using species-specific peptide nucleic acid (PNA) probe hybridisation, and quantitatively evaluated by RT-PCR Candida quantification methodology. Furthermore, gene (BCR1 and HWP1) expression of biofilm and RHVE-colonising cells was evaluated by quantitative RT-PCR. Results confirmed that progesterone reduced the capacity of C. albicans strains to form biofilms and to colonise and invade RHVE. Additionally, it was demonstrated that progesterone decreased expression of BCR1 and HWP1, which are important virulence determinants of C. albicans. In conclusion, it was evident that progesterone can have a major influence on C. albicans pathogenicity on vaginal epithelial cells and may partly explain susceptibility of women to VVC at different stages of the menstrual cycle.

    Humans are colonized by thousands of bacterial species, but it is difficult to assess the metabolic and pathogenic potential of the majority of these because they have yet to be cultured. Here, we characterize an uncultivated vaginal mycoplasma tightly associated with trichomoniasis that was previously known by its 16S rRNA sequence as “Mnola.” In this study, the mycoplasma was found almost exclusively in women infected with the sexually transmitted pathogen Trichomonas vaginalis, but rarely observed in women with no diagnosed disease. The genomes of four strains of this species were reconstructed using metagenome sequencing and assembly of DNA from four discrete mid-vaginal samples, one of which was obtained from a pregnant woman with trichomoniasis who delivered prematurely. These bacteria harbor several putative virulence factors and display unique metabolic strategies. Genes encoding proteins with high similarity to potential virulence factors include two collagenases, a hemolysin, an O-sialoglycoprotein endopeptidase and a feoB-type ferrous iron transport system. We propose the name “Candidatus Mycoplasma girerdii” for this potential new pathogen. PMID:25337710

  20. Dietary supplementation with probiotics during late pregnancy: outcome on vaginal microbiota and cytokine secretion

    PubMed Central

    2012-01-01

    Background The vaginal microbiota of healthy women consists of a wide variety of anaerobic and aerobic bacterial genera and species dominated by the genus Lactobacillus. The activity of lactobacilli helps to maintain the natural healthy balance of the vaginal microbiota. This role is particularly important during pregnancy because vaginal dismicrobism is one of the most important mechanisms for preterm birth and perinatal complications. In the present study, we characterized the impact of a dietary supplementation with the probiotic VSL#3, a mixture of Lactobacillus, Bifidobacterium and Streptococcus strains, on the vaginal microbiota and immunological profiles of healthy women during late pregnancy. Results An association between the oral intake of the probiotic VSL#3 and changes in the composition of the vaginal microbiota of pregnant women was revealed by PCR-DGGE population profiling. Despite no significant changes were found in the amounts of the principal vaginal bacterial populations in women administered with VSL#3, qPCR results suggested a potential role of the probiotic product in counteracting the decrease of Bifidobacterium and the increase of Atopobium, that occurred in control women during late pregnancy. The modulation of the vaginal microbiota was associated with significant changes in some vaginal cytokines. In particular, the decrease of the anti-inflammatory cytokines IL-4 and IL-10 was observed only in control women but not in women supplemented with VSL#3. In addition, the probiotic consumption induced the decrease of the pro-inflammatory chemokine Eotaxin, suggesting a potential anti-inflammatory effect on the vaginal immunity. Conclusion Dietary supplementation with the probiotic VSL#3 during the last trimester of pregnancy was associated to a modulation of the vaginal microbiota and cytokine secretion, with potential implications in preventing preterm birth.

The performance of LAVH was compared with that of VH, in a tertiary care hospital. The procedures were performed by the same surgeon. Results: There was no significant difference in terms of age, parity, body weight or uterine weight. The mean estimated blood loss in LAVH was significantly lower when compared with the VH group (126.5±39.8 ml and 100±32.8 ml), respectively. As to postoperative pain, less diclofenac was required in the LAVH group compared to the VH group (70.38±13.45 mg and 75.18±16.45 mg), respectively. Conclusions: LAVH, is clinically and economically comparable to VH, with patient benefits of less estimated blood loss, lower quantity of analgesia use, lower rate of intra- and postoperative complications, less postoperative pain, rapid patient recovery, and shorter hospital stay.

  2. Longitudinal analysis of the vaginal microflora in pregnancy suggests that L. crispatus promotes the stability of the normal vaginal microflora and that L. gasseri and/or L. iners are more conducive to the occurrence of abnormal vaginal microflora

    Background Despite their antimicrobial potential, vaginal lactobacilli often fail to retain dominance, resulting in overgrowth of the vagina by other bacteria, as observed with bacterial vaginosis. It remains elusive however to what extent interindividual differences in vaginal Lactobacillus community composition determine the stability of this microflora. In a prospective cohort of pregnant women we studied the stability of the normal vaginal microflora (assessed on Gram stain) as a function of the presence of the vaginal Lactobacillus index species (determined through culture and molecular analysis with tRFLP). Results From 100 consecutive Caucasian women vaginal swabs were obtained at mean gestational ages of 8.6 (SD 1.4), 21.2 (SD 1.3), and 32.4 (SD 1.7) weeks, respectively. Based on Gram stain, 77 women had normal or Lactobacillus-dominated vaginal microflora (VMF) during the first trimester, of which 18 had grade Ia (L. crispatus cell morphotypes) VMF (23.4%), 16 grade Iab (L. crispatus and other Lactobacillus cell morphotypes) VMF (20.8%), and 43 grade Ib (non-L. crispatus cell morphotypes) VMF (55.8%). Thirteen women with normal VMF at baseline, converted in the second or third trimester (16.9%) to abnormal VMF defined as VMF dominated by non-Lactobacillus bacteria. Compared to grade Ia and grade Iab VMF, grade Ib VMF were 10 times (RR = 9.49, 95% CI 1.30 – 69.40) more likely to convert from normal to abnormal VMF (p = 0.009). This was explained by the observation that normal VMF comprising L. gasseri/iners incurred a ten-fold increased risk of conversion to abnormal VMF relative to non-L. gasseri/iners VMF (RR 10.41, 95% CI 1.39–78.12, p = 0.008), whereas normal VMF comprising L. crispatus had a five-fold decreased risk of conversion to abnormal VMF relative to non-L. crispatus VMF (RR 0.20, 95% CI 0.05–0.89, p = 0.04). Conclusion The presence of different Lactobacillus species with the normal vaginal microflora is a major determinant to the stability of this microflora in pregnancy: L. crispatus promotes the stability of the normal vaginal microflora while L. gasseri and/or L. iners predispose to some extent to the occurrence of abnormal vaginal microflora.

    Objectives The non-nucleoside reverse transcriptase inhibitor MC1220 has potent in vitro activity against HIV type 1 (HIV-1). A liposome gel formulation of MC1220 has previously been reported to partially protect rhesus macaques against vaginal challenge with a simian HIV (SHIV). Here, we describe the pre-clinical development of an MC1220-releasing silicone elastomer vaginal ring (SEVR), including pharmacokinetic (PK) and efficacy studies in macaques. Methods In vitro release studies were conducted on SEVRs loaded with 400 mg of MC1220, using simulated vaginal fluid (SVF, n?=?4) and 1?:?1 isopropanol/water (IPA/H2O, n?=?4) as release media. For PK evaluation, SEVRs were inserted into adult female macaques (n?=?6) for 30 days. Following a 1week washout period, fresh rings were placed in the same animals, which were then challenged vaginally with RT-SHIV162P3 once weekly for 4 weeks. Results SEVRs released 1.66 and 101 mg of MC1220 into SVF and IPA/H2O, respectively, over 30 days, the differential reflecting the low aqueous solubility of the drug. In macaque PK studies, MC1220 was consistently detected in vaginal fluid (peak 845 ng/mL) and plasma (peak 0.91 ng/mL). KaplanMeier analysis over 9weeks showed significantly lower infection rates for animals given MC1220-containing SEVRs than placebo rings (hazard ratio 0.20, P?=?0.0037). Conclusions An MC1220-releasing SEVR partially protected macaques from vaginal challenge. Such ring devices are a practical method for providing sustained, coitally independent protection against vaginal exposure to HIV-1. PMID:23109186

    Objective To assess actual rates of late vaginal stenosis and identify predisposing factors for complications among patients with previously untreated cervical cancer following high-dose-rate brachytherapy. Methods We performed longitudinal analyses of 57 patients using the modified Dische score at 6, 12, 18, 24, 36, and 60 months after treatment, which consisted of 15 interstitial brachytherapys and 42 conventional intracavitary brachytherapys, with a median follow-up time of 36 months (range, 6 to 144 months). Results More than half of the patients developed grade 1 (mild) vaginal stenosis within the first year of follow-up, and grade 2 (97.5%, moderate) to grade 3 (severe) stenosis gradually increased with time. Actual stenosis rates for grade 1, 2, and 3 were 97.5% (95% confidence interval [CI], 92.7 to 97.5), 60.7% (95% CI, 42.2 to 79.3), and 7.4% (95% CI, 0 to 18.4) at 3 years after treatment. Pallor reaction grade 2-3 at 6 months was only a statistically significant predisposing factor for grade 2-3 late vaginal stenosis 3 years or later with a hazard ratio of 3.48 (95% CI, 1.32 to 9.19; p=0.018) by a multivariate Cox proportional hazard model. Patients with grade 0-1 pallor reaction at 6 months showed a grade ?2 vaginal stenosis rate of 53%, whereas the grade 2-3 pallor reaction group achieved a grade ?2 vaginal stenosis rate at 3 years at 100% (p=0.001). Conclusion High-dose-rate brachytherapy was associated with high incidence of late vaginal stenosis. Pallor reaction grade 2-3 at 6 months was predictive of late grade 2-3 vaginal stenosis at 3 years after treatment. These findings should prove helpful for patient counseling and preventive intervention. PMID:25925294

    In humans, the vaginal microbiota is thought to be the first line of defense again pathogens including Chlamydia trachomatis. The guinea pig has been extensively used as a model to study chlamydial infection because it shares anatomical and physiological similarities with humans, such as a squamous vaginal epithelium as well as some of the long-term outcomes caused by chlamydial infection. In this study, we aimed to evaluate the guinea pig-C. caviae model of genital infection as a surrogate for studying the role of the vaginal microbiota in the early steps of C. trachomatis infection in humans. We used culture-independent molecular methods to characterize the relative and absolute abundance of bacterial phylotypes in the guinea pig vaginal microbiota in animals non-infected, mock-infected or infected by C. caviae. We showed that the guinea pig and human vaginal microbiotas are of different bacterial composition and abundance. Chlamydia caviae infection had a profound effect on the absolute abundance of bacterial phylotypes but not on the composition of the guinea pig vaginal microbiota. Our findings compromise the validity of the guinea pig-C. caviae model to study the role of the vaginal microbiota during the early steps of sexually transmitted infection. PMID:25761873

    Exposure of newborns to the maternal vaginal microbiota is interrupted with cesarean birthing. Babies delivered by cesarean section (C-section) acquire a microbiota that differs from that of vaginally delivered infants, and C-section delivery has been associated with increased risk for immune and metabolic disorders. Here we conducted a pilot study in which infants delivered by C-section were exposed to maternal vaginal fluids at birth. Similarly to vaginally delivered babies, the gut, oral and skin bacterial communities of these newborns during the first 30 d of life was enriched in vaginal bacteria-which were underrepresented in unexposed C-section-delivered infants-and the microbiome similarity to those of vaginally delivered infants was greater in oral and skin samples than in anal samples. Although the long-term health consequences of restoring the microbiota of C-section-delivered infants remain unclear, our results demonstrate that vaginal microbes can be partially restored at birth in C-section-delivered babies.

    Design of a liposome delivery system for vaginal administration of acyclovir, able to provide sustained release and improved bioavailability of the encapsulated drug for the local treatment of genital herpes was investigated. Acyclovir was encapsulated in liposomes prepared by the polyol dilution method, whereby various phospholipid compositions were used: egg phosphatidylcholin (PC)/egg phosphatidylglycerol (PG) 9:1, egg phosphatidylcholine (PC) and egg phosphatidycholine (PC)/stearylamine (SA) 9:3. All liposome preparations were characterized and compared for particle size, polydispersity, encapsulation efficiency and tested for in vitro stability in different media chosen to simulate human vaginal conditions: buffer, pH 4.5 (corresponding to normal human vaginal pH), vaginal fluid simulant (medium developed so as to mimic the fluid produced in the vagina) with or without mucin. To be closer to in vivo application of liposomes and to achieve further improvement of their stability, liposomes were incorporated in a vehicle suitable for vaginal self-administration. Bioadhesive hydrogel made from Carbopol 974P NF resin with adequate pH value and desirable viscosity was chosen as a vehicle for liposomes containing acyclovir. In vitro release studies of liposomes incorporated in the hydrogel proved their applicability as a novel vaginal delivery system with localized and sustained release of encapsulated acyclovir. Even after 24 h of incubation in vaginal fluid simulant more than 35% of the originally encapsulated drug was retained in the hydrogel. PMID:15979189

    Vaginal candidiasis or vulvovaginal candidiasis (VC) is a common mucosal infection of vagina, mainly caused by Candida species. The major symptoms of VC are dyspareunia, pruritis, itching, soreness, vagina as well as vulvar erythema and edema. Most common risk factors that lead to the imbalance in the vaginal micro biota are the use of antibiotics, pregnancy, diabetes mellitus, immuno suppression as in AIDS or HIV patients, frequent sexual intercourse, spermicide and intra-uterine devices and vaginal douching. Various anti-fungal drugs are available for effective treatment of VC. Different conventional vaginal formulations (creams, gels, suppositories, powder, ointment, etc.) for VC are available today but have limited efficacy because of lesser residence time on vaginal epithelium due to self-cleansing action of vagina. So to overcome this problem, an extended and intimate contact with vaginal mucosa is desired; which can be accomplished by utilizing mucoadhesive polymers. Mucoadhesive polymers have an excellent binding capacity to mucosal tissues for considerable period of time. This unique property of these polymers significantly enhances retention time of different formulations on mucosal tissues. Currently, various novel formulations such as liposomes, nano- and microparticles, micro-emulsions, bio-adhesive gel and tablets are used to control and treat VC. In this review, we focused on current status of vaginal candidiasis, conventional and nanotechnology inspired formulation approaches. PMID:24959937

    In Syrian hamsters (Mesocricetus auratus), precopulatory behaviors such as vaginal scent marking are essential for attracting a suitable mate. Vaginal marking is dependent on forebrain areas implicated in the neural regulation of reproductive behaviors in rodents, including the medial preoptic/anterior hypothalamus (MPOA-AH). Within MPOA-AH, the neuropeptide oxytocin (OT) acts to facilitate copulation (lordosis), as well as ultrasonic vocalizations towards males. It is not known, however, if OT in this area also facilitates vaginal marking. In the present study, a specific oxytocin receptor antagonist (OTA) was injected into MPOA-AH of intact female Syrian hamsters to determine if oxytocin receptor-dependent signaling is critical for the normal expression of vaginal marking elicited by male, female, and clean odors. OTA injections significantly inhibited vaginal marking in response to male odors compared to vehicle injections. There was no effect of OTA on marking in response to either female or clean odors. When injected into the bed nucleus of the stria terminalis (BNST), a nearby region to MPOA-AH, OTA was equally effective in decreasing marking. Finally, the effects of OTA appear to be specific to vaginal marking, as OTA injections in MPOA-AH or BNST did not alter general locomotor activity, flank marking, or social odor investigation. Considered together, these results suggest that OT in MPOA-AH and/or BNST normally facilitates male odor-induced vaginal marking, providing further evidence that OT generally supports prosocial interactions among conspecifics.

    Objective To evaluate the bioavailability and safety of a novel vaginal capsule containing solubilized bioidentical 17β-estradiol for vulvar and vaginal atrophy and compare its pharmacokinetics with that of an approved vaginal estradiol tablet in healthy postmenopausal women. Methods Two randomized, single-dose, two-way cross-over, relative bioavailability trials compared the pharmacokinetics of a solubilized vaginal estradiol softgel capsule (TX-004HR, test) with that of a vaginal estradiol tablet (Vagifem®, reference) in postmenopausal women (aged 40-65 years) at 10-μg and 25-μg doses. In each study, women were randomly assigned to receive a single dose of the test capsule or reference tablet, followed by a single dose of the alternate drug after a 14-day washout. Results Thirty-five women completed the 10-μg study and 36 completed the 25-μg study. Significantly lower systemic levels of estradiol, estrone, and estrone sulfate at both doses of the test product were observed compared with equivalent doses of the reference product, with lower AUC0-24 and Cmax and earlier tmax. No adverse events were reported in either trial. Conclusion TX-004HR, a novel estradiol vaginal softgel capsule, exhibited significantly lower systemic exposure than equivalent doses of an approved vaginal estradiol tablet at both 10-μg and 25-μg doses. Both doses of each product were safe and well-tolerated. PMID:26857443

    The composition and structure of the pregnancy vaginal microbiome may influence susceptibility to adverse pregnancy outcomes. Studies on the pregnant vaginal microbiome have largely been limited to Northern American populations. Using MiSeq sequencing of 16S rRNA gene amplicons, we characterised the vaginal microbiota of a mixed British cohort of women (n = 42) who experienced uncomplicated term delivery and who were sampled longitudinally throughout pregnancy (8–12, 20–22, 28–30 and 34–36 weeks gestation) and 6 weeks postpartum. We show that vaginal microbiome composition dramatically changes postpartum to become less Lactobacillus spp. dominant with increased alpha-diversity irrespective of the community structure during pregnancy and independent of ethnicity. While the pregnancy vaginal microbiome was characteristically dominated by Lactobacillus spp. and low alpha-diversity, unlike Northern American populations, a significant number of pregnant women this British population had a L. jensenii-dominated microbiome characterised by low alpha-diversity. L. jensenii was predominantly observed in women of Asian and Caucasian ethnicity whereas L. gasseri was absent in samples from Black women. This study reveals new insights into biogeographical and ethnic effects upon the pregnancy and postpartum vaginal microbiome and has important implications for future studies exploring relationships between the vaginal microbiome, host health and pregnancy outcomes.

    The purpose of this work was to design and optimize a novel vaginal drug delivery system for more effective treatment against vaginal candidiasis. Itraconazole was formulated in bioadhesive film formulations that could be retained in the vagina for prolonged intervals. The polymeric films were prepared by solvent evaporation and optimized for various physicodynamic and aesthetic properties. In addition, percentage drug retained on vaginal mucosa was evaluated using a simulated dynamic vaginal system as function of time. A polymeric film containing 100 mg itraconazole per unit (2.5 cm x 2.5 cm) have been developed using generally regarded as safe listed excipients. The pH of vaginal film was found to be slightly acidic (4.90 +/- 0.04) in simulated vaginal fluid and alkaline (7.04 +/- 0.07) in water. The little moisture content (7.66 +/- 0.51% w/w) was present in the film, which helps them to remain stable and kept them from being completely dry and brittle. The mechanical properties, tensile strength, and percentage elongation at break (9.64 N/mm(2) and 67.56% for ITRF(65)) reveal that the formulations were found to be soft and tough. The films (ITRF(65)) contained solid dispersion of itraconazole (2.5)/hydroxypropyl cellulose (1)/polyethylene glycol 400 (0.5), which was found to be the optimal composition for a novel bioadhesive vaginal formulation, as they showed good peelability, relatively good swelling index, and moderate tensile strength and retained vaginal mucosa up to 8 h. Also, the film did not markedly affect normal vaginal flora (lactobacillus) and was noncytotoxic as indicated by the negligible decrease in cell viability. PMID:19629707

    Purpose: Most physicians use a single-channel vaginal cylinder for postoperative endometrial cancer brachytherapy. Recent published data have identified air pockets between the vaginal cylinders and the vaginal mucosa. The purpose of this research was to evaluate the incidence, size, and dosimetric effects of these air pockets. Methods and Materials: 25 patients receiving postoperative vaginal cuff brachytherapy with a high-dose rate vaginal cylinders were enrolled in this prospective data collection study. Patients were treated with 6 fractions of 200 to 400 cGy per fraction prescribed at 5 mm depth. Computed tomography simulation for brachytherapy treatment planning was performed for each fraction. The quantity, volume, and dosimetric impact of the air pockets surrounding the cylinder were quantified. Results: In 25 patients, a total of 90 air pockets were present in 150 procedures (60%). Five patients had no air pockets present during any of their treatments. The average number of air pockets per patient was 3.6, with the average total air pocket volume being 0.34 cm{sup 3} (range, 0.01-1.32 cm{sup 3}). The average dose reduction to the vaginal mucosa at the air pocket was 27% (range, 9-58%). Ten patients had no air pockets on their first fraction but air pockets occurred in subsequent fractions. Conclusion: Air pockets between high-dose rate vaginal cylinder applicators and the vaginal mucosa are present in the majority of fractions of therapy, and their presence varies from patient to patient and fraction to fraction. The existence of air pockets results in reduced radiation dose to the vaginal mucosa.

    Vaginal glycogen is degraded by host ?-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 ?-amylase activity may promote dominance of Lactobacilli. We evaluated whether the ?-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 ?-amylase, secretory leukocyte protease inhibitor (SLPI), hyaluronan, hyaluronidase-1, ?-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 ?-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 ?-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 ?-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. PMID:25878210

    Wireless Body Sensors for medical purposes offer valuable contributions to improve patients’ healthcare, including diagnosis and/or therapeutics monitoring. Body temperature is a crucial parameter in healthcare diagnosis. In gynecology and obstetrics it is measured at the skin’s surface, which is very influenced by the environment. This paper proposes a new intra-body sensor for long-term intra-vaginal temperature collection. The embedded IEEE 802.15.4 communication module allows the integration of this sensor in a Wireless Sensor Network (WSN) for remote data access and monitoring. We present the sensor architecture, the construction of the corresponding testbed, and its performance evaluation. This sensor may be used in different medical applications, including preterm labor prevention and fertility and ovulation period detection. The features of the constructed testbed were validated in laboratory tests verifying its accuracy and performance. PMID:22163471

    Adenocarcinoma of the cervix is a rare condition that has shown an increase in incidence, especially in the 20- to 34-year-old group. Adenocarcinoma represents about 5-10% of all tumours in this area, and, among these, the clear cell type accounts for 4-9%. This type of tumour affects mainly postmenopausal women but also occurs in young women with a history of prenatal exposure to diethylstilbestrol (DES). The prognosis for adenocarcinoma of the cervix is poor overall and worse for the clear cell variety. This article discusses a case of clear cell adenocarcinoma of the cervix, unrelated to intrauterine exposure to DES, in a woman of childbearing age who wished to preserve her fertility and was therefore treated by radical vaginal trachelectomy and pelvic lymphadenectomy.

    Vulvovaginal candidiasis (VVC) is a frequent disease affecting more than 75% of all women at least once in their lifetime. Up to 8% of them suffer from recurrent VVC (RVVC) characterized by at least three episodes each year. Several risk factors, such as antibiotic use, diabetes, or pregnancy, are known, but the vast majority of women with RVVC develop the infection without having any risk factor, implying that a genetic component most likely plays an important role in the susceptibility to RVVC. This review summarizes the immunogenetic alterations that lead to an increased susceptibility to vaginal infections with Candida albicans. Different mutations and polymorphisms in innate immune genes alter the mucosal immune response against fungi and are likely to have an important role in susceptibility to RVVC. A better understanding of the genetic and immunological mechanisms leading to RVVC is important for both the understanding of the pathophysiology of the disease and the design of novel therapeutic strategies.

    Objectives When Lactobacillus spp. dominate the vaginal microbiota of women of reproductive age they acidify the vagina to pH <4.0 by producing ∼1% lactic acid in a nearly racemic mixture of d- and l-isomers. We determined the HIV virucidal activity of racemic lactic acid, and its d- and l-isomers, compared with acetic acid and acidity alone (by the addition of HCl). Methods HIV-1 and HIV-2 were transiently treated with acids in the absence or presence of human genital secretions at 37°C for different time intervals, then immediately neutralized and residual infectivity determined in the TZM-bl reporter cell line. Results l-lactic acid at 0.3% (w/w) was 17-fold more potent than d-lactic acid in inactivating HIVBa-L. Complete inactivation of different HIV-1 subtypes and HIV-2 was achieved with ≥0.4% (w/w) l-lactic acid. At a typical vaginal pH of 3.8, l-lactic acid at 1% (w/w) more potently and rapidly inactivated HIVBa-L and HIV-1 transmitter/founder strains compared with 1% (w/w) acetic acid and with acidity alone, all adjusted to pH 3.8. A final concentration of 1% (w/w) l-lactic acid maximally inactivated HIVBa-L in the presence of cervicovaginal secretions and seminal plasma. The anti-HIV activity of l-lactic acid was pH dependent, being abrogated at neutral pH, indicating that its virucidal activity is mediated by protonated lactic acid and not the lactate anion. Conclusions l-lactic acid at physiological concentrations demonstrates potent HIV virucidal activity distinct from acidity alone and greater than acetic acid, suggesting a protective role in the sexual transmission of HIV.

    Vaginal microbiome studies provide information which may change the way we define vaginal flora. Normal flora appears dominated by one or two species of Lactobacillus. Significant numbers of healthy women lack appreciable numbers of vaginal lactobacilli. Bacterial vaginosis (BV) is not a single entity, but different bacterial communities or profiles of greater microbial diversity than is evident from cultivation-dependent studies. BV should be considered a syndrome of variable composition which results in different symptoms, phenotypical outcomes, and responses to different antibiotic regimens. This information may help to elucidate the link between BV and infection-related adverse outcomes of pregnancy. PMID:21251190

    We report a case of 26-year-old primipara with last child birth 1.5 year back who presented with amenorrhoea, cyclical lower abdominal pain and dyspareunia for past six months. Examination revealed vaginal atresia secondary to previous traumatic/mismanaged vaginal delivery with haematocolpos. She was managed by vaginoplasty with amnion graft and regular dilation with soft vaginal mould for six weeks and was advised for regular intercourse after that. On follow up our patient was doing well with restoration of normal coital function. PMID:25584275

    A safe and effective vaginal microbicide could decrease human immunodeficiency virus (HIV) transmission in women. Here, we evaluated the safety and microbicidal efficacy of a short amphipathic peptide, C5A, in a rhesus macaque model. We found that a vaginal application of C5A protects 89% of the macaques from a simian-human immunodeficiency virus (SHIV-162P3) challenge. We observed no signs of lesions or inflammation in animals vaginally treated with repeated C5A applications. With its noncellular cytotoxic activity and rare mechanism of action, C5A represents an attractive microbicidal candidate. PMID:26552985

    High performance ion exchange chromatography was employed to evaluate the presence of short chain organic acids in the vaginal fluid of a woman troubled by persistent foul vaginal odor, but who did not have typical bacterial vaginosis. The vaginal secretions from this patient were collected on a weighed cotton swab and eluted into water and extracted by acidified ether. Salts of the acids were back-extracted into aqueous solution and chromatographed on an H-form resin column and compared to commercially available standards. A strikingly large amount of caproic acid was found. The caproic acid disappeared after metronidazole therapy, and a subsequent follow-up chromatogram showed a predominance of lactic acid. The success of this technique in evaluating the present case suggests that such a method may prove useful in other types of vaginal infection. PMID:3506838

    A 52-year-old woman was referred to the gynecology outpatient clinic with a 2 months history of vaginal bleeding with intercourse, and no other symptoms. Vaginal examination revealed a firm, non-tender, mass in the posterior vaginal wall. The initial clinical impression was that of a vaginal carcinoma and a biopsy under local anesthesia was performed, but the result was inconclusive. A deeper biopsy, under general anesthesia, was performed and a histological diagnosis of non-Hodgkins lymphoma was done. The staging workup permitted to exclude any other site of the body affected by the malignancy. Hematologists reviewed the patient and recommended chemotherapy. A complete tumor regression was observed and the patient has now a disease-free survival of 72 months. This case report intends to create awareness of this rare clinical entity. Although the gynecologist will rarely be faced to extranodal lymphoma, it should be included in the differential diagnosis of gynecologic malignancies.

    The vaginal microbiome is believed to influence host health by providing protection from pathogens and influencing reproductive outcomes such as fertility and gestational length. In humans, age-associated declines in diversity of the vaginal microbiome occur in puberty and persist into adulthood. Additionally, menstruation has been associated with decreased microbial community stability. Adult female baboons, like other non-human primates (NHPs), have a different and highly diverse vaginal microbiome compared to that of humans, which is most commonly dominated by Lactobacillus spp. We evaluated the influence of age, reproductive cycling status (cycling vs. non-cycling) and menstruation on the vaginal microbiome of 38 wild-caught, captive female olive baboons (Papio anubis) by culture-independent sequencing of the V3-V5 region of the bacterial 16S rRNA gene. All baboons had highly diverse vaginal microbial communities. Adult baboons had significantly lower microbial diversity in comparison to subadult baboons, which was attributable to decreased relative abundance of minor taxa. No significant differences were detected based on cycling state or menstruation. Predictive metagenomic analysis showed uniformity in relative abundance of metabolic pathways regardless of age, cycle stage, or menstruation, indicating conservation of microbial community functions. This study suggests that selection of an optimal vaginal microbial community occurs at puberty. Since decreased diversity occurs in both baboons and humans at puberty, this may reflect a general strategy for selection of adult vaginal microbial communities. Comparative evaluation of vaginal microbial community development and composition may elucidate mechanisms of community formation and function that are conserved across host species or across microbial community types. These findings have implications for host health, evolutionary biology, and microbe-host ecosystems. PMID:25676781

    Vulvovaginal candidiasis, caused primarily by Candida albicans, presents significant health issues for women of childbearing age. As a polymorphic fungus, the ability of C. albicans to switch between yeast and hyphal morphologies is considered its central virulence attribute. Armed with new criteria for defining vaginitis immunopathology, the purpose of this study was to determine whether the yeast-to-hypha transition is required for the hallmark inflammatory responses previously characterized during murine vaginitis. Kinetic analyses of vaginal infection with C. albicans in C57BL/6 mice demonstrated that fungal burdens remained constant throughout the observation period, while polymorphonuclear leukocyte (PMN), S100A8, and interleukin-1? levels obtained from vaginal lavage fluid increased by day 3 onward. Lactate dehydrogenase activity was also positively correlated with increased effectors of innate immunity. Additionally, immunodepletion of neutrophils in infected mice confirmed a nonprotective role for PMNs during vaginitis. Determination of the importance of fungal morphogenesis during vaginitis was addressed with a two-pronged approach. Intravaginal inoculation of mice with C. albicans strains deleted for key transcriptional regulators (bcr1?/?, efg1?/?, cph1?/?, and efg1?/? cph1?/?) controlling the yeast-to-hypha switch revealed a crucial role for morphogenetic signaling through the Efg1 and, to a lesser extent, the Bcr1 pathways in contributing to vaginitis immunopathology. Furthermore, overexpression of transcription factors NRG1 and UME6, to maintain yeast and hyphal morphologies, respectively, confirmed the importance of morphogenesis in generating innate immune responses in vivo. These results highlight the yeast-to-hypha switch and the associated morphogenetic response as important virulence components for the immunopathogenesis of Candida vaginitis, with implications for transition from benign colonization to symptomatic infection.

    Introduction Hysterectomy is one of the most common gyneacological surgeries performed worldwide. The vaginal technique has been introduced and performed centuries back, but has been less successful due to lack of experience and enthusiasm among Gynaecologists, due to a misconception that the abdominal route is safer and easier. Aim To evaluate the most efficient route of hysterectomy in women with mobile nonprolapsed uteri of 12 weeks or lesser by comparing the intra and postoperative complications of vaginal and abdominal hysterectomies. Materials and Methods A prospective, randomized controlled trial was performed wherein, 300 consecutive patients requiring hysterectomy for benign diseases were analysed over a period of 2 years (December 2012–November 2014). Group A (n = 150) underwent vaginal hysterectomy (non descent vaginal hysterectomy, NDVH) which was compared with group B (n = 150) who had abdominal hysterectomy. The primary outcome measures were operative time, intraoperative blood loss, postoperative analgesia, hospital stay, postoperative mobility, blood transfusion, wound infection, febrile morbidity and postoperative systemic infections. Secondary outcome measures were conversion of vaginal to abdominal route and re-laparotomy. Results Baseline characteristics were similar between the two groups. There were no intraoperative complications in either group. Regarding operation duration, intraoperative blood loss, postoperative pain, postoperative blood transfusion, mobilization in post operative ward, postoperative wound infection, febrile morbidity, duration of hospital stay, p-value was significant in vaginal hysterectomy compared to abdominal hysterectomy. Regarding postoperative systemic infections, p-value was not significant. None of the cases in the vaginal group were converted to abdominal route and none of the cases in the whole study group underwent re-laparotomy. Conclusion The present study concludes that patients requiring hysterectomy for benign non prolapse cases may be offered the option of vaginal hysterectomy which has quicker recovery, shorter hospitalization, lesser operative and postoperative morbidity compared to abdominal route.

    Background: Most of the women suffer from vaginal atrophy and dryness, and therefore, efficient and safe treatment is needed to improve vaginal lubrication. Vitamin D has several important functions which may be effective in proliferation and repair of the epithelial tissue. This study aimed to evaluate the effect of vitamin D vaginal suppositories on maturation index, pH, and dryness in postmenopausal women. Materials and Methods: Women were enrolled in this double-blind clinical trial, in whom menopause occurred at least one year ago. Those women who had an abnormal Papanicolaou smear, had undergone hormonal treatment, or have had vaginal infection in the previous year were excluded. Forty-four women who found eligible were randomized into two equal groups, the treatment and control groups, which received vitamin D and placebo vaginal suppository daily for 8 weeks, respectively. Vaginal pH and maturation value were measured at the beginning and end of the study. Pain, dryness, and paleness were assessed before treatment and at the end of the 2, 4, and 8 weeks of treatment. Results: In the treatment group, the number (Mean SD) of superficial cells increased (69.76 12.4) and vaginal pH decreased (1.42 0.67) significantly compared to the control group after 56 days. The mean pain significantly reduced after 8 weeks in the treatment group (1.23 0.53) compared to the control group 1.95 0.74 (P < 0.001). The mean of dryness and paleness reduced significantly in the treatment group versus control at 56 days. Conclusions: Vitamin D is effective in improving the maturation index and decreased the pH and dryness of the vaginal atrophy due to menopause. PMID:25878698

    Objective: The vagina has been studied as a favorable site for the local and systemic delivery of drugs, for female associated conditions. Vaginal preparations, although generally perceived as safer most still associated with number of problems including multiple days of dosing, dripping, leakage and messiness, causing discomfort to users and expulsion due to the self-cleansing action of the vaginal tract. These limitations lead to poor patient compliance and failure of the desired therapeutic effects. For efficient vaginal delivery of drugs, the delivery system should reside at the site of infection for a prolonged period of time. In situ gel formulation which combines advantages of both gels and solution so that an accurate dose can be administered with ease. These formulations remain in solution state before administration and transforms to gel after administration in to vaginal cavity. Material and Methods: In these formulations we prepared clindamycin loaded hydroxypropyl methycellulose (0.1%) (bioadhesive) and gellan gum (ion activated gelling polymer) based in situ gel system for vaginal application. NaCl (0.9%) was added as an isotonic agent. The developed formulation was characterized for various in vitro parameters such as clarity, refractive index, pH, viscosity, drug release profile, statistical release kinetics, bioadhesive force, and microbial efficacy along with stability studies. To simulate vaginal conditions, synthetic membrane (cellophane hydrated with modified simulated vaginal fluid) was used as model membranes. Results and Discussion: The developed formulation was found to be nonirritant, bioadhesive with good retention properties. Formulations have satisfactory appearance, clarity and drug content in the range 98.1-101%. Refractive index of the gel is ranging from 1.335 to 1.337, proofing the transparency of gel. Furthermore, formulation displayed 33.3% cumulative drug release after 2 h. 67.4% after 6 h and 98.9% after 12 h. Conclusion: Developed formulation should be stable. Hence, formulation is thus a viable alternative to conventional vaginal dosage forms. PMID:25599033

    The last step of a successful pregnancy is the safe delivery of the fetus. An important question is if the delivery should vaginal or operative. In addition to the use of conventional antenatal ultrasound, the use of intrapartum ultrasound to evaluate fetal head station, position, cervical ripening, and placental separation is promising. This review evaluates and summarizes the usefulness of intrapartum ultrasound for the evaluation of labor progress and predicting successful operative vaginal delivery. PMID:25469329

    Recent studies demonstrated that intravaginal rings (IVRs) containing 100 mg of the nonnucleoside reverse transcriptase inhibitor (NNRTI) MIV-150 significantly protect macaques against a chimeric simian-human immunodeficiency virus that expresses the HIV-1 HxB2 reverse transcriptase (SHIV-RT) when present before and after vaginal challenge. The objectives of this study were to (i) evaluate the pharmacodynamics (PD) of MIV-150 in vaginal fluids (VF) and in ectocervical and vaginal tissues following 100-mg MIV-150 IVR exposure and to (ii) gain more insight whether pharmacokinetics (PK) of MIV-150 can predict PD. MIV-150 in VF collected at 1 day and 14 days post-MIV-150 IVR insertion inhibited ex vivo SHIV-RT infection in vaginal biopsy specimens from untreated animals (not carrying IVRs) in a dose-dependent manner. Previous PK studies demonstrated a significant increase of ectocervical and vaginal tissue MIV-150 concentrations 14 days versus 1 day post-IVR insertion, with the highest increase in vaginal tissue. Therefore, we tested PD of MIV-150 in tissues 14 days post-MIV-150 IVR insertion. Ex vivo SHIV-RT infection of vaginal, but not ectocervical, tissues collected 14 days post-MIV-150 IVR insertion was significantly inhibited compared to infection at the baseline (prior to MIV-150 IVR exposure). No changes in vaginal and ectocervical tissue infection were observed after placebo IVR exposure. Overall, these data underscore the use of the ex vivo macaque explant challenge models to evaluate tissue and VF PK/PD of candidate microbicides before in vivo animal efficacy studies. The data support further development of MIV-150-containing IVRs. PMID:24614384

    After menopause, many women experience vaginal dryness and atrophy of tissue, often attributed to the loss of estrogen. An understudied aspect of vaginal health in women who experience dryness due to atrophy is the role of the resident microbes. It is known that the microbiota has an important role in healthy vaginal homeostasis, including maintaining the pH balance and excluding pathogens. The objectives of this study were twofold: first to identify the microbiome of post-menopausal women with and without vaginal dryness and symptoms of atrophy; and secondly to examine any differences in epithelial gene expression associated with atrophy. The vaginal microbiome of 32 post-menopausal women was profiled using Illumina sequencing of the V6 region of the 16S rRNA gene. Sixteen subjects were selected for follow-up sampling every two weeks for 10 weeks. In addition, 10 epithelial RNA samples (6 healthy and 4 experiencing vaginal dryness) were acquired for gene expression analysis by Affymetrix Human Gene array. The microbiota abundance profiles were relatively stable over 10 weeks compared to previously published data on premenopausal women. There was an inverse correlation between Lactobacillus ratio and dryness and an increased bacterial diversity in women experiencing moderate to severe vaginal dryness. In healthy participants, Lactobacillus iners and L. crispatus were generally the most abundant, countering the long-held view that lactobacilli are absent or depleted in menopause. Vaginal dryness and atrophy were associated with down-regulation of human genes involved in maintenance of epithelial structure and barrier function, while those associated with inflammation were up-regulated consistent with the adverse clinical presentation.

    Objectives Describe the effect of 50mcg vaginal 17-β-estradiol (E2) cream on vaginal maturation, serum estrogen levels, atrophic symptoms, and biomarkers of oxidative stress and tissue remodeling in postmenopausal women without prolapse. Methods Seventeen women, 65 years or older, applied intravaginal E2 cream nightly for eight weeks, then twice weekly for eight weeks. Vaginal biopsies, serial blood draws, and atrophic symptoms were obtained at baseline, eight, and sixteen weeks. Changes in atrophic symptoms, vaginal maturation indices (VMI), and serum E2 were measured. Immunohistochemical staining characterized levels of transforming growth factor-beta (TGF-β), nuclear factor kappa B (NFKB), inducible nitric oxide synthase (iNOS), endothelial nitric oxide synthase (eNOS), and thrombospondin (TSP). Results Serum E2 levels (pg/mL) were unchanged from baseline (mean (SD)) 7.7 (3.3) to eight 9.7 (5.7) and sixteen 8.7 (5.8) (p=0.24) weeks. VMI (mean (SD)) improved from baseline 34.2 (18.3) to eight 56.7 (13.1) and sixteen 54.5 (11.3) (p<0.001) weeks with no difference between eight and sixteen weeks. Vaginal dryness (p=0.03) and itching (p=0.02) improved. Tissue biomarker levels did not change (TGF-β p=0.35, NFKB p=0.74, eNOS p=0.80, iNOS p=0.24, TSP p=0.80). Discussion Vaginal E2 improved atrophic symptoms and VMI without elevating serum E2. Tissue remodeling biomarkers did not change. PMID:26115591

    MucoCept is a biotherapeutic for prevention of HIV-1 infection in women and contains a human, vaginal Lactobacillus jensenii that has been genetically enhanced to express the HIV-1 entry inhibitor, modified cyanovirin-N (mCV-N). The objective of this study was to develop a solid vaginal dosage form that supports sustained vaginal colonization of the MucoCept Lactobacillus at levels previously shown, with freshly prepared cultures, to protect macaques from SHIV infection and to test this formulation in a macaque vaginal colonization model. Vaginally disintegrating tablets were prepared by lyophilizing the formulated bacteria in tablet-shaped molds, then packaging in foil pouches with desiccant. Disintegration time, potency and stability of the tablets were assessed. For colonization, non-synchronized macaques were dosed vaginally with either one tablet or five tablets delivered over five days. Vaginal samples were obtained at three, 14, and 21 days post-dosing and cultured to determine Lactobacillus colonization levels. To confirm identity of the MucoCept Lactobacillus strain, genomic DNA was extracted from samples on days 14 and 21 and a strain-specific PCR was performed. Supernatants from bacteria were tested for the presence of the mCV-N protein by Western blot. The tablets were easy to handle, disintegrated within two minutes, potent (5.7x1011 CFU/g), and stable at 4C and 25C. Vaginal administration of the tablets to macaques resulted in colonization of the MucoCept Lactobacillus in 66% of macaques at 14 days post-dosing and 83% after 21 days. There was no significant difference in colonization levels for the one or five tablet dosing regimens (p=0.88 Day 14, p=0.99 Day 21). Strain-specific PCR confirmed the presence of the bacteria even in culture-negative macaques. Finally, the presence of mCV-N protein was confirmed by Western blot analysis using a specific anti-mCV-N antibody. PMID:25875100

    Sexual function outcomes were analyzed in a group of women (n = 78) presenting for vaginal rejuvenation/vaginoplasty procedure for a chief complaint of vaginal laxity and decreased sensation with intercourse. Outcomes were analyzed utilizing the validated Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire-12 (PISQ-12) before and at least 6 months after repair with vaginal rejuvenation/vaginoplasty procedure (VR). Mean age was 43.6 ± 7.9 (range 25-62), and 19 patients (24.3%) were found to have prolapse at time of initial exam and underwent vaginal vault suspension in addition to VR. Compared preoperatively and postoperatively, the overall sexual function (Total PISQ-12) statistically improved (30.3 ± 6.6 vs. 38.2 ± 5.2, P < 0.001). All individual scores statistically improved except in 3 categories in which there was no change (Q1-desire, Q5-pain, and Q11- partner premature ejaculation). Overall sexual satisfaction improved as well as subcategories of increased sexual excitement during intercourse and overall increase in intensity of orgasms. Pain with intercourse subscores were found to be no different from preoperatively to postoperatively. Previous studies have shown that sexual function improves with repair of prolapse; however, this is the first study to show improved function using a validated questionnaire in patients undergoing VR for laxity.

    Vaginal pre-exposure prophylaxis has focused heavily on gel formulations. Low adherence linked with frequent dosing and short therapeutic duration has emerged as the major reason for inconsistent efficacy outcomes with gels in clinical trials. Osmotic pumps can achieve versatile drug release profiles however, have not been explored for vaginal delivery. In this report, we describe an osmotic pump tablet (OPT) that can deliver antiretrovirals for several days. We also describe configuring the OPT for pH sensitive delivery where the drug delivery system consistently delivers a antiretroviral at vaginal pH and then gives a burst release triggered by a coitally associated pH increase. We have investigated the vaginal OPT for multiple day delivery of a potent antiretroviral, IQP-0528 in a sheep model. To effectively register spatial drug distribution we also engineered a tool to precisely collect multiple vaginal fluid samples. In a 10-day duration post single application, high micromolar mucosal levels were obtained with peak concentration more than 6 logs higher than IQP-0528 EC50. Overall, our results show successful implementation of the osmotic pump technology for vaginal antiretroviral delivery. PMID:23973812

    Candida glabrata is the second most common organism isolated from women with vulvovaginal candidiasis (VVC), particularly in women with uncontrolled diabetes mellitus. However, mechanisms involved in the pathogenesis of C. glabrata-associated VVC are unknown and have not been studied at any depth in animal models. The objective of this study was to evaluate host responses to infection following efforts to optimize a murine model of C. glabrata VVC. For this, various designs were evaluated for consistent experimental vaginal colonization (i.e., type 1 and type 2 diabetic mice, exogenous estrogen, varying inocula, and co-infection with C. albicans). Upon model optimization, vaginal fungal burden and polymorphonuclear neutrophil (PMN) recruitment were assessed longitudinally over 21 days post-inoculation, together with vaginal concentrations of IL-1β, S100A8 alarmin, lactate dehydrogenase (LDH), and in vivo biofilm formation. Consistent and sustained vaginal colonization with C. glabrata was achieved in estrogenized streptozotocin-induced type 1 diabetic mice. Vaginal PMN infiltration was consistently low, with IL-1β, S100A8, and LDH concentrations similar to uninoculated mice. Biofilm formation was not detected in vivo, and co-infection with C. albicans did not induce synergistic immunopathogenic effects. This data suggests that experimental vaginal colonization of C. glabrata is not associated with an inflammatory immunopathogenic response or biofilm formation. PMID:26807975

    One of the most frequent complaints for post-menopausal women is vaginal atrophy, because of reduction in circulating oestrogens. Treatments based on local oestrogen administration have been questioned as topic oestrogens can reach the bloodstream, thus leading to consider their safety as controversial, especially for patients with a history of breast or endometrial cancers. Recently, growth factors have been shown to interact with the oestrogen pathway, but the mechanisms still need to be fully clarified. In this study, we investigated the effect of keratinocyte growth factor (KGF), a known mitogen for epithelial cells, on human vaginal mucosa cells, and its potential crosstalk with oestrogen pathways. We also tested the in vivo efficacy of KGF local administration on vaginal atrophy in a murine model. We demonstrated that KGF is able to induce proliferation of vaginal mucosa, and we gained insight on its mechanism of action by highlighting its contribution to switch ERα signalling towards non-genomic pathway. Moreover, we demonstrated that KGF restores vaginal trophism in vivo similarly to intravaginal oestrogenic preparations, without systemic effects. Therefore, we suggest a possible alternative therapy for vaginal atrophy devoid of the risks related to oestrogen-based treatments, and a patent (no. RM2012A000404) has been applied for this study.

    Candida glabrata is the second most common organism isolated from women with vulvovaginal candidiasis (VVC), particularly in women with uncontrolled diabetes mellitus. However, mechanisms involved in the pathogenesis of C. glabrata-associated VVC are unknown and have not been studied at any depth in animal models. The objective of this study was to evaluate host responses to infection following efforts to optimize a murine model of C. glabrata VVC. For this, various designs were evaluated for consistent experimental vaginal colonization (i.e., type 1 and type 2 diabetic mice, exogenous estrogen, varying inocula, and co-infection with C. albicans). Upon model optimization, vaginal fungal burden and polymorphonuclear neutrophil (PMN) recruitment were assessed longitudinally over 21 days post-inoculation, together with vaginal concentrations of IL-1β, S100A8 alarmin, lactate dehydrogenase (LDH), and in vivo biofilm formation. Consistent and sustained vaginal colonization with C. glabrata was achieved in estrogenized streptozotocin-induced type 1 diabetic mice. Vaginal PMN infiltration was consistently low, with IL-1β, S100A8, and LDH concentrations similar to uninoculated mice. Biofilm formation was not detected in vivo, and co-infection with C. albicans did not induce synergistic immunopathogenic effects. This data suggests that experimental vaginal colonization of C. glabrata is not associated with an inflammatory immunopathogenic response or biofilm formation. PMID:26807975

    Background Use of a levonorgestrel-releasing intrauterine system (LNG-IUS) in humans may alter vaginal microbial populations and susceptibility to pathogens. This study evaluated the time-dependent effects of an LNG-IUS on the vaginal microbiome of the baboon, a useful animal model for reproductive studies. Methods LNG-IUS were inserted into three reproductively mature, female baboons. The animals were evaluated for six months by physical examination and Gram-stained cytology. The vaginal microbiota was characterized at each timepoint by culture-independent analysis of the16S rRNA-encoding gene. Results Each baboon harbored a diverse vaginal microbiome. Inter-individual variation exceeded intra-individual variation. Diversity declined over time in one baboon and showed mild fluctuations in the other two. There were no significant community differences from early to late post LNG-IUS placement. Conclusions The baboon vaginal microbiome is unique to each individual and is polymicrobial. In this pilot study, the vaginal microbiome remained stable from early to late post LNG-IUS placement. PMID:24266633

    Purpose: Although vaginal dilation is often recommended to minimize or prevent vaginal scarring after pelvic radiotherapy, compliance with this recommendation has historically been very low. Therefore, effective intervention strategies are needed to enhance compliance with vaginal dilation after radiotherapy for gynecologic cancer. Methods and Materials: This study was a randomized controlled clinical trial of a psychoeducational intervention specifically designed to increase compliance with vaginal dilation. The information-motivation-behavioral skills model of enhancing compliance with behavioral change was the basis for the intervention design. Forty-two sexually active women, 21 to 65 years of age, diagnosed with Stages Ic-III cervical or endometrial cancer, who received pelvic radiotherapy, were randomized to either the experimental psychoeducational group or the information-only control group. Assessment via questionnaire occurred before treatment and at 6-week, 6-month, 12-month, 18-month, and 24-month follow-up. Assessment via interview also occurred at 6-month, 12-month, 18-month, and 24-month follow-up. Results: The psychoeducational intervention was successful in increasing compliance with vaginal dilation. Conclusions: This study is the first randomized controlled study to demonstrate the effectiveness of an intervention in increasing compliance with the use of vaginal dilators.

    To fully understand late adolescents' experiences of oral sex, we must consider both risk and normative developmental perspectives. Sexual experiences include a range of behaviors, but research on sexual behaviors and consequences focuses primarily on vaginal sex. Oral sex occurs at rates similar to vaginal sex, and carries some, though less, risk than vaginal sex. The current study examined the event-level prevalence and consequences of oral sex compared to vaginal sex with other-sex partners in first-year college students. Daily data were from recently sexually active first-year college students (N = 253 people, 834 days; M age, 18.4 years; SD = 0.4; 56 % female; 31 % Hispanic/Latino; 17 % African American, 14 % Asian American/Pacific Islander, 25 % European American, 12 % multiracial) who reported on sexual behaviors and consequences. Both positive (intimacy, physical satisfaction) and negative (worrying about health, guilt) consequences were less common for oral than vaginal sex. Gender differences suggested that female adolescents may find vaginal sex more rewarding than oral sex, whereas male adolescents may find them equally rewarding. PMID:26597646

    Objective To determine the prevalence of vaginal infections and associated lifestyles of students visiting the University of Cape Coast Hospital. Methods Fifty female students presenting with clinical symptoms of vaginitis were sampled. One hundred samples made up of 50 urine and 50 higher vaginal swabs (HVS) were obtained from patients and questionnaire administered. Samples were wet prepared, examined microscopically, and cultured on blood and chocolate agars for 24 h at (352) C. Colonial morphology, Gram reactions and biochemical tests were used for the identification of isolates. Results There were high percentages of pus cells (64%), epithelial cells (62%) and yeast cells (56%) in all urine samples. Bacterial isolates included Staphylococcus aureus (28%) and (22%), Klebsiella spp. (6%) and (4%) in urine and HVS samples respectively; Escherichia coli in urine (18%) and Candida in HVS (16%). The overall prevalence of vaginitis was 66%, including bacterial vaginosis 28%, Candida infection 22% and co-infection of bacterial and Candida 16%. Lifestyle data showed all sampled students were sexually active, 48% used contraceptives, 54% used antimicrobial agents, and 92% prefered wearing of trousers and shorts. Conclusions The present study indicates prevalence of vaginal infection among female students, which strongly correlates with student lifestyle. Education on lifestyle modifications will go a long way in reducing the prevalence of vaginitis.

  7. Treating vulvovaginal atrophy/genitourinary syndrome of menopause: how important is vaginal lubricant and moisturizer composition?

    Vaginal dryness is a common condition that is particularly prevalent during and after the menopause, and is one of the symptoms of vulvovaginal atrophy/genitourinary syndrome of menopause. The impact of vaginal dryness on interpersonal relationships, quality of life, daily activities, and sexual function can be significant, but is frequently underestimated. Furthermore, barriers exist to treatment-seeking, and this condition is often underreported and undertreated. Greater education about vaginal dryness and the range of available treatments is essential to encourage more women to seek help for this condition. Personal lubricants and moisturizers are effective at relieving discomfort and pain during sexual intercourse for women with mild to moderate vaginal dryness, particularly those who have a genuine contraindication to estrogen, or who choose not to use estrogen. However, there is a distinction between lubricants and moisturizers, and notable differences between commercially available products. Women should be advised to choose a product that is optimally balanced in terms of both osmolality and pH, and is physiologically most similar to natural vaginal secretions. A series of recommendations for the use of vaginal lubricants and moisturizers, either on their own or in combination with systemic or topical hormone replacement therapy, is presented.

    Vaginal pre-exposure prophylaxis has focused heavily on gel formulations. Low adherence linked with frequent dosing and short therapeutic duration has emerged as the major reason for inconsistent efficacy outcomes with gels in clinical trials. Osmotic pumps can achieve versatile drug release profiles however, have not been explored for vaginal delivery. In this report, we describe an osmotic pump tablet (OPT) that can deliver antiretrovirals for several days. We also describe configuring the OPT for pH sensitive delivery where the drug delivery system consistently delivers an antiretroviral at vaginal pH and then gives a burst release triggered by a coitally associated pH increase. We have investigated the vaginal OPT for multiple day delivery of a potent antiretroviral, IQP-0528 in a sheep model. To effectively register spatial drug distribution we also engineered a tool to precisely collect multiple vaginal fluid samples. In a 10-day duration post single application, high micromolar mucosal levels were obtained with peak concentration more than 6 logs higher than the EC50 of IQP-0528. Overall, our results show successful implementation of the osmotic pump technology for vaginal antiretroviral delivery. PMID:23973812

    Objective. We investigated the use of miconazole among female prostitutes in Costa Rica as well as the distribution of vaginal yeasts and the susceptibility pattern to azoles of strains obtained from this population. Our intention was to relate a frequent use of miconazole to occurrence of vaginal yeasts resistant to azoles. Methods. Vaginal samples were taken from 277 patients that have previously used azoles. Vaginal swabs were obtained for direct microscopy and culture. Yeast isolates were identified by germ tube test and assimilation pattern. Susceptibility testing was determined using a tablet diffusion method. Results. The number of clinical Candida isolates (one from each patient) was 57 (20.6%). C. albicans was the predominant species (70%), followed by C. parapsilosis (12%), C. tropicalis (5.3%), C. glabrata and C. famata (3.5% each), C. krusei, C. inconspicua and C. guilliermondii (1.7% each). The majority of vaginal Candida isolates were susceptible to ketoconazole (91%), fluconazole (96.5%), and itraconazole (98%). A lower susceptibility of some isolates to miconazole (63%) was observed as compared to the other azoles tested. Moreover, the strains, nonsusceptible to miconazole, were more often obtained from patients that have used this antifungal at least four times within the last year before taking the samples as compared to those with three or less treatments (P<.01). Conclusion. An indiscriminate use of miconazole, such as that observed among female prostitutes in Costa Rica, results in a reduced susceptibility of vaginal yeasts to miconazole but not to other azoles.

    Radiation-induced vaginal fibrosis is a debilitating side-effect affecting up to 80% of women receiving radiotherapy for their gynecological (GYN) malignancies. Despite the significant incidence and severity, little research has been conducted to identify the pathophysiologic changes of vaginal toxicity. In a previous study, we have demonstrated that ultrasound Nakagami shape and PDF parameters can be used to quantify radiation-induced vaginal toxicity. These Nakagami parameters are derived from the statistics of ultrasound backscattered signals to capture the physical properties (e.g., arrangement and distribution) of the biological tissues. In this paper, we propose to expand this Nakagami imaging concept from 2D to 3D to fully characterize radiation-induced changes to the vaginal wall within the radiation treatment field. A pilot study with 5 post-radiotherapy GYN patients was conducted using a clinical ultrasound scanner (6 MHz) with a mechanical stepper. A serial of 2D ultrasound images, with radio-frequency (RF) signals, were acquired at 1 mm step size. The 2D Nakagami shape and PDF parameters were calculated from the RF signal envelope with a sliding window, and then 3D Nakagami parameter images were generated from the parallel 2D images. This imaging method may be useful as we try to monitor radiation-induced vaginal injury, and address vaginal toxicities and sexual dysfunction in women after radiotherapy for GYN malignancies.

    Microbicides are being actively researched and developed as woman-initiated means to prevent HIV transmission during unprotected coitus. Along with safety and efficacy, assessing and improving compliance is a major area of research in microbicide development. We have developed carrageenan-based semisoft vaginal suppositories and have previously evaluated how physical properties such as firmness, size and shape influence womens willingness to try them. Firmness has previously been quantified in terms of small-strain storage modulus, G, however large-strain properties of the gels may also play a role in the firmness perception. In the current study we prepared two sets of suppositories with the same G but different elongation properties at four different G values (250, 2500, 12,500, 25,000 Pa): For convenience we refer to these as brittle and elastic, although these terms were never provided to study participants. In the first of two tests conducted to assess preference, women compared pairs of brittle and elastic suppositories and indicated their preference. We observed an interaction, as women preferred brittle suppositories at lower G (250, 2500 Pa) and elastic ones at a higher G (25,000 Pa). In the second test, women evaluated samples across different G, rated the ease-of-insertion and willingness-to-try and ranked the samples in order of preference. Brittle suppositories at G of 12,500 Pa were most preferred. In vitro studies were also conducted to measure the softening of the suppositories in contact with vaginal simulant fluid (VSF). Release of antiretroviral drug tenofovir in VSF was quantified for the brittle and elastic suppositories at G of 12,500 Pa to determine the effect of suppository type on release. The initial rate of release was 20% slower with elastic suppositories as compared to brittle suppositories. Understanding how different physical properties simultaneously affect womens preferences and pharmacological efficacy in terms of drug release is required for the optimization of highly acceptable and efficacious microbicides.

    Background Deployed military women have an increased risk for development of vaginitis due to extreme temperatures, primitive sanitation, hygiene and laundry facilities, and unavailable or unacceptable health care resources. The Women in the Military Self-Diagnosis (WMSD) and Treatment Kit was developed as a field-expedient solution to this problem. Objectives The primary study aims were to evaluate the accuracy of womens self-diagnosis of vaginal symptoms and 8 diagnostic algorithms, and to predict potential self-medication omission and commission error rates. Method Participants included 546 active duty, deployable Army (43.3%) and Navy (53.6%) women with vaginal symptoms who sought health care at troop medical clinics on base. In the clinic lavatory, women conducted a self-diagnosis using a sterile cotton swab to obtain vaginal fluid, a FemExam card to measure positive or negative pH and amines, and the investigator-developed WMSD Decision-Making guide. Potential self-diagnoses were bacterial infection (bacterial vaginosis and/or trichomonas vaginitis - BV/TV), yeast infection (candida vaginitis CV), no infection/normal, or unclear. The Affirm VPIII laboratory reference standard was used to detect clinically significant amounts of vaginal fluid DNA for organisms associated with BV, TV and CV. Results Womens self-diagnostic accuracy was 56% for BV/TV and 69.2% for CV. False positives would have led to a self-medication commission error rate of 20.3% for BV/TV and 8% for CV. Potential self-medication omission error rates due to false negatives were 23.7% for BV/TV and 24.8% for CV. The positive predictive power (PPV) of diagnostic algorithms for BV/TV ranged from 0 to 78.1%, and for CV was 41.7%. Discussion The algorithms were based on clinical diagnostic standards. The non-specific nature of vaginal symptoms, mixed infections, and a faulty device intended to measure vaginal pH and amines explain why none of the algorithms reached the goal of 95% accuracy. The next prototype of the WMSD Kit will not include non-specific vaginal signs and symptoms in favor of recently available point-of-care devices that identify antigens or enzymes of the causative BV, TV, and CV organisms.

    Background Poor obstetrical outcomes are associated with imbalances in the vaginal flora. The present study evaluated the role of vaginal Lactobacillus species in women with intermediate vaginal flora with regard to obstetrical outcomes. Methods We retrospectively analysed data from all women with singleton pregnancies who had undergone routine screening for asymptomatic vaginal infections at our tertiary referral centre between 2005 and 2014. Vaginal smears were Gram-stained and classified according to the Nugent scoring system as normal flora (score 03), intermediate vaginal flora (46), or bacterial vaginosis (710). Only women with intermediate vaginal flora were investigated. Women with a Nugent score of 4 were categorised into those with and without Lactobacilli. Follow-up smears were obtained 46 weeks after the initial smears. Descriptive data analysis, the Welchs t-test, the Fishers exact test, and multiple regression analysis with adjustment for confounders were performed. Gestational age at delivery and birth weight were the outcome measures. Results At antenatal screening, 529/8421 women presented with intermediate vaginal flora. Amongst these, 349/529 (66%) had a Nugent score of 4, 94/529 (17.8%) a Nugent score of 5, and 86/529 (16.2%) a Nugent score of 6. Amongst those with a Nugent score of 4, 232/349 (66.5%) women were in the Lactobacilli group and 117/349 (33.5%) in the Non-Lactobacilli group. The preterm delivery rate was significantly lower in the Lactobacilli than in the Non-Lactobacilli group (OR 0.34, CI 0.210.55; p<0.001). Mean birth weight was 2979 842 g and 2388 1155 g in the study groups, respectively (MD 564.12, CI 346.23781.92; p<0.001). On follow-up smears, bacterial vaginosis rates were 9% in the Lactobacilli and 7.8% in the Non-Lactobacilli group. Conclusions The absence of vaginal Lactobacillus species and any bacterial colonisation increases the risks of preterm delivery and low birth weight in women with intermediate vaginal flora in early pregnancy.

    The various microbiota normally associated with the human body have an important influence on human development, physiology, immunity, and nutrition. This is certainly true for the vagina wherein communities of mutualistic bacteria constitute the first line of defense for the host by excluding invasive, nonindigenous organisms that may cause disease. In recent years much has been learned about the bacterial species composition of these communities and how they differ between individuals of different ages and ethnicities. A deeper understanding of their origins and the interrelationships of constituent species is needed to understand how and why they change over time or in response to changes in the host environment. Moreover, there are few unifying theories to explain the ecological dynamics of vaginal ecosystems as they respond to disturbances caused by menses and human activities such as intercourse, douching, and other habits and practices. This fundamental knowledge is needed to diagnose and assess risk to disease. Here we summarize what is known about the species composition, structure, and function of bacterial communities in the human vagina and the applicability of ecological models of community structure and function to understanding the dynamics of this and other ecosystems that comprise the human microbiome.

    The human microbiome, the collective genome of the microbial community that is on and within us, has recently been mapped. The initial characterization of healthy subjects has provided investigators with a reference population for interrogating the microbiome in metabolic, intestinal, and reproductive health and disease states. Although it is known that bacteria can colonize the vagina, recent metagenomic studies have shown that the vaginal microbiome varies among reproductive age women. Similarly, the richness and diversity of intestinal microbiota also naturally fluctuate among gravidae in both human and nonhuman primates, as well as mice. Moreover, recent evidence suggests that microbiome niches in pregnancy are not limited to maternal body sites, as the placenta appears to harbor a low biomass microbiome that is presumptively established in early pregnancy and varies in association with a remote history of maternal antenatal infection as well as preterm birth. In this article, we will provide a brief overview on metagenomics science as a means to investigate the microbiome, observations pertaining to both variation and the presumptive potential role of a varied microbiome during pregnancy, and how future studies of the microbiome in pregnancy may lend to a better understanding of human biology, reproductive health, and parturition.

    Malignant melanoma of the vulva and vagina is relatively uncommon and accounts for <5% of all melanomas in women. The aim of our study was to establish the biological properties and evaluate potential therapeutic targets in these tumors. We collected a series of 65 cases from three centers and re-evaluated the tumor tissue for predominant growth pattern (superficial spreading, nodular, and mucosal lentiginous) and tumor thickness. KIT (CD117) expression was detected immunohistochemically. In addition, tumors were screened for BRAF, NRAS, and KIT mutations by PCR and DNA sequencing as well as for KIT amplifications by fluorescence in situ hybridization. None of the cases contained BRAF mutations. NRAS mutations and KIT amplifications were detected in similar frequency (?12%) in tumors of the vulva and vagina. In contrast, KIT mutations were present in 18% of primary melanomas of the vulva, but in none of the tumors arising in the vagina. Moderate or strong KIT protein expression was detected in 30 cases, including all tumors with KIT mutations and 6 of the 7 with KIT amplifications. In conclusion, BRAF mutations are virtually absent in melanomas originating from the vulva or vagina, whereas NRAS mutations and KIT amplifications occur in both locations. KIT mutations appear to be specific for melanomas of the vulva, suggesting that in spite of the anatomic proximity, the development of vulvar and vaginal melanomas involves different molecular alterations which may be targeted by novel treatment approaches.

    Background and Objectives: To evaluate whether the route and surgical technique by which hysterectomy is performed influence the incidence of vaginal cuff dehiscence. Methods: We performed a retrospective analysis of total hysterectomy cases performed at Brigham and Woman's Hospital or Faulkner Hospital during 2009 through 2011. Results: During the study period, 2382 total hysterectomies were performed; 23 of these (0.96%) were diagnosed with cuff dehiscence, and 4 women had recurrent dehiscence. Both laparoscopic (odds ratio, 23.4; P = .007) and robotic (odds ratio, 73; P = .0006) hysterectomies were associated with increased odds of cuff dehiscence in a multivariate regression analysis. The type of energy used during colpotomy, mode of closure (hand sewn, laparoscopic suturing, or suturing assisted by a device), and suture material did not differ significantly between groups; however, continuous suturing of the cuff was a protective factor (odds ratio, 0.24; P = .03). Women with dehiscence had more extensive procedures, as well as an increased incidence of additional major postoperative complications (17.4% vs 3%, P = .004). Conclusion: The rate of cuff dehiscence in our cohort correlates with the current literature. This study suggests that the risk of dehiscence is influenced mainly by the scope and complexity of the surgical procedure. It seems that different colpotomy techniques do not influence the rate of cuff dehiscence; however, continuous suturing of the cuff may be superior to interrupted suturing. PMID:25901104

  18. Prediction of scar integrity and vaginal birth after caesarean delivery.

    PubMed

    Valentin, Lil

    2013-04-01

    A statistically significant association with uterine rupture during a trial of labour after caesarean delivery was found in at least two studies for the following variables: inter-delivery interval (higher risk with short interval), birth weight (higher risk if 4000 g or over), induction of labour (higher risk), oxytocin dose (higher risk with higher doses), and previous vaginal delivery (lower risk). However, no clinically useful risk estimation model that includes clinical variables has been published. A thin lower uterine segment at 35-40 weeks, as measured by ultrasound in women with a caesarean hysterotomy scar, increases the risk of uterine rupture or dehiscence. No cut-off for lower uterine segment thickness, however, can be suggested because of study heterogeneity, and because prospective validation is lacking. Large caesarean hysterotomy scar defects in non-pregnant women seen at ultrasound examination increase the risk of uterine rupture or dehiscence in subsequent pregnancy, but the strength of the association is unknown. To sum up, we currently lack a method that can provide a reliable estimate of the risk of uterine rupture or dehiscence during a trial of labour in women with caesarean hysterotomy scar(s).

    The human vagina is a complex and dynamic ecosystem containing an abundance of microorganisms. In women of childbearing age, this system is dominated by Lactobacillus spp. In the present work, seventeen newly isolated vaginal strains were identified by 16S rDNA sequencing and were investigated for their antimicrobial properties. Twelve of the isolated Lactobacillus strains showed activity against one or more microorganisms. Six and five of them produced substances that inhibited the growth of two different Klebsiella strains and Staphylococcus aureus, respectively. Two lactobacilli strains were active against an Escherichia coli strain, one isolate was active against an Enterococus faecalis strain and another lactobacilli strain showed antimicrobial activity against a Candida parapsilosis strain. The nature of the active compounds was additionally studied, and the presence of bacteriocin-like substances was proved. The genes related to the bacteriocin production in three of the newly isolated strains were identified and sequenced. The presence of gassericin A operon in the genome of the species Lactobacillus crispatus was described for the first time. The presence of antimicrobial activity contributes to their possible use as potential probiotic strains after further research. PMID:24919535

The aim of this paper is to evaluate under in vitro conditions resembling the vaginal microenvironment, the antifungal activity of a new propiconazole derivative against 64 strains of yeast species isolated from vulvovaginitis. The tests exhibited low MICs for all strains and this finding may be useful in using of this new azole compound for treatment of mycotic vaginitis. PMID:18293715

    A broad-spectrum vaginal microbicide must be effective against a variety of sexually transmitted disease pathogens and be minimally toxic to the cell types found within the vaginal epithelium, including vaginal keratinocytes. We assessed the sensitivity of primary human vaginal keratinocytes to potential topical vaginal microbicides nonoxynol-9 (N-9), C31G, and sodium dodecyl sulfate (SDS). Direct immunofluorescence and fluorescence-activated cell sorting analyses demonstrated that primary vaginal keratinocytes expressed epithelial cell-specific keratin proteins. Experiments that compared vaginal keratinocyte sensitivity to each agent during a continuous, 48-h exposure demonstrated that primary vaginal keratinocytes were almost five times more sensitive to N-9 than to either C31G or SDS. To evaluate the effect of multiple microbicide exposures on cell viability, primary vaginal keratinocytes were exposed to N-9, C31G, or SDS three times during a 78-h period. In these experiments, cells were considerably more sensitive to C31G than to N-9 or SDS at lower concentrations within the range tested. When agent concentrations were chosen to result in an endpoint of 25% viability after three daily exposures, each exposure decreased cell viability at the same constant rate. When time-dependent sensitivity during a continuous 48-h exposure was examined, exposure to C31G for 18 h resulted in losses in cell viability not caused by either N-9 or SDS until at least 24 to 48 h. Cumulatively, these results reveal important variations in time- and concentration-dependent sensitivity to N-9, C31G, or SDS within populations of primary human vaginal keratinocytes cultured in vitro. These investigations represent initial steps toward both in vitro modeling of the vaginal microenvironment and studies of factors that impact the in vivo efficacy of vaginal topical microbicides.

    The majority of uncomplicated vulvovaginal complaints (e.g. bacterial vaginosis, vulvovaginal candidiasis, trichomoniasis) can be detected with uncomplicated basic infectiological tests and can usually be treated effectively without requiring further diagnostic procedures. Tests include measurement of vaginal pH, preparation and assessment of wet mount slides prepared from vaginal or cervical discharge, and the correct clinical and microbiological classification of findings. In Germany, at least in recent years, this has not been sufficiently taught or practiced. As new regulations on specialist gynecologic training in Germany are currently being drawn up, this overview provides basic information on gynecologic infectiology and summarizes clinically relevant aspects of recent microbiological findings on the physiology and pathology of vaginal flora. The clinical signs and symptoms of aerobic vaginitis, the pathogenesis of which is still not completely understood, are also reviewed. Finally, the symptoms, indications and risk factors for pelvic inflammatory disease (PID) are presented. In contrast to the above-listed infections, PID requires immediate culture of the pathogen from samples (e.g. obtained by laparoscopy) with microbiological diagnostic procedures carried out by specialist laboratories. A schematic summary of all pathologies discussed here is presented. PMID:26028693

    Vaginal small interfering RNA (siRNA) delivery provides a promising strategy for the prevention and treatment of vaginal diseases. However, the densely cross-linked mucus layer on the vaginal wall severely restricts nanoparticle-mediated siRNA delivery to the vaginal epithelium. In order to overcome this barrier and enhance vaginal mucus penetration, we prepared spray-dried powders containing siRNA-loaded nanoparticles. Powders with Pluronic F127 (F127), hydroxypropyl methyl cellulose (HPMC), and mannitol as carriers were obtained using an ultrasound-assisted spray-drying technique. Highly dispersed dry powders with diameters of 5–15 μm were produced. These powders showed effective siRNA protection and sustained release. The mucus-penetrating properties of the powders differed depending on their compositions. They exhibited different potential of opening mesh size of molecular sieve in simulated vaginal mucus system. A powder formulation with 0.6% F127 and 0.1% HPMC produced the maximum increase in the pore size of the model gel used to simulate vaginal mucus by rapidly extracting water from the gel and interacting with the gel; the resulting modulation of the molecular sieve effect achieved a 17.8-fold improvement of siRNA delivery in vaginal tract and effective siRNA delivery to the epithelium. This study suggests that powder formulations with optimized compositions have the potential to alter the steric barrier posed by mucus and hold promise for effective vaginal siRNA delivery.

    Vaginal fluid is one of the most common body fluids found at crime scenes. Discriminating vaginal fluid from other body fluids is important in forensic science; however, few potential protein markers have been reported to date. Proteomic methods for identifying protein markers have gained attention, although few reports have applied this technology to forensic protein markers. Therefore, to identify characteristic vaginal proteins, we examined various body fluids (nasal secretions, saliva, urine, semen, vaginal fluids, and sweat) using liquid chromatography/electrospray ionization time-of-flight mass spectrometry and peptide mass fingerprinting. We identified three components (average molecular mass values 17,237??2, 18,063??2, and 15,075??1) detectable only in vaginal samples: two human small proline-rich protein 3 (SPRR3) isoforms and a human fatty acid-binding protein 5 (FABP5) with an acetylated (+42) N-terminal region lacking the initiator methionine residue (-131). Using ELISA, these yielded markedly high average values in vaginal fluids. The mass spectra of these proteins were not detected in infant saliva but were detected in the vaginal fluid throughout the menstrual cycle. The results of forensic analysis (detection limit, mixed body fluid samples, casework samples, and blind samples) suggest that these proteins are potential forensic markers. In conclusion, high SPRR3 and FABP5 expression levels, which may be used as potential markers for vaginal fluid identification in forensic science, were detected in vaginal fluids from healthy adults.

    Background To determine if oral metronidazole (MTZ-400mg bid) with 2% vaginal clindamycin-cream (Clind) or a Lactobacillus acidophilus vaginal-probiotic containing oestriol (Prob) reduces 6-month bacterial vaginosis (BV) recurrence. Methods Double-blind placebo-controlled parallel-group single-site study with balanced randomization (1?1?1) conducted at Melbourne Sexual Health Centre, Australia. Participants with symptomatic BV [Nugent Score (NS)?=?710 or ?3 Amsel's criteria and NS?=?410], were randomly allocated to MTZ-Clind, MTZ-Prob or MTZ-Placebo and assessed at 1,2,3 and 6 months. MTZ and Clind were administered for 7 days and Prob and Placebo for 12 days. Primary outcome was BV recurrence (NS of 710) on self-collected vaginal-swabs over 6-months. Cumulative BV recurrence rates were compared between groups by Chi-squared statistics. Kaplan-Meier, log rank and Cox regression analyses were used to compare time until and risk of BV recurrence between groups. Results 450 1850 year old females were randomized and 408 (91%), equally distributed between groups, provided ?1 NS post-randomization and were included in analyses; 42 (9%) participants with no post-randomization data were excluded. Six-month retention rates were 78% (n?=?351). One-month BV recurrence (NS 710) rates were 3.6% (5/140), 6.8% (9/133) and 9.6% (13/135) in the MTZ-Clind, MTZ-Prob and MTZ-Placebo groups respectively, p?=?0.13. Hazard ratios (HR) for BV recurrence at one-month, adjusted for adherence to vaginal therapy, were 0.43 (95%CI 0.151.22) and 0.75 (95% CI 0.321.76) in the MTZ-Clind and MTZ-Prob groups compared to MTZ-Plac respectively. Cumulative 6-month BV recurrence was 28.2%; (95%CI 24.032.7%) with no difference between groups, p?=?0.82; HRs for 6-month BV recurrence for MTZ-Clind and MTZ-Prob compared to MTZ-Plac, adjusted for adherence to vaginal therapy were 1.09(95% CI?=?0.701.70) and 1.03(95% CI?=?0.651.63), respectively. No serious adverse events occurred. Conclusion Combining the recommended first line therapies of oral metronidazole and vaginal clindamycin, or oral metronidazole with an extended-course of a commercially available vaginal-L.acidophilus probiotic, does not reduce BV recurrence.

    Menstrual toxic shock syndrome (mTSS) is a rare, recognizable, and treatable disease that has been associated with tampon use epidemiologically. It involves a confluence of microbial risk factors (Staphylococcus aureus strains that produce the superantigen—TSST-1), as well as environmental characteristics of the vaginal ecosystem during menstruation and host susceptibility factors. This paper describes a series of experiments using the well-characterized model of porcine vaginal mucosa ex-vivo to assess the effect of these factors associated with tampon use on the permeability of the mucosa. The flux of radiolabeled TSST-1 and tritiated water ({sup 3}H{sub 2}O) through porcine vaginal mucosa was determined at various temperatures, after mechanical disruption of the epithelial surface by tape stripping, after treatment with surfactants or other compounds, and in the presence of microbial virulence factors. Elevated temperatures (42, 47 and 52 °C) did not significantly increase flux of {sup 3}H{sub 2}O. Stripping of the epithelial layers significantly increased the flux of labeled toxin in a dose-dependent manner. Addition of benzalkonium chloride (0.1 and 0.5%) and glycerol (4%) significantly increased the flux of {sup 3}H{sub 2}O but sodium lauryl sulfate at any concentration tested did not. The flux of the labeled toxin was significantly increased in the presence of benzalkonium chloride but not Pluronic® L92 and Tween 20 and significantly increased with addition of α-hemolysin but not endotoxin. These results show that the permeability of porcine vagina ex-vivo to labeled toxin or water can be used to evaluate changes to the vaginal environment and modifications in tampon materials, and thus aid in risk assessment. - Highlights: • Model assessed local effects of tampon use on vaginal mucosa. • Risks were evaluated using two tracers to assess permeability in an ex vivo model. • Mechanical damage to the epithelial surface increased tracer penetration. • Surfactants increased penetration of tracers across vaginal mucosa. • Alpha-hemolysin increased the penetration of bacterial toxin across vaginal mucosa.

    Whether or not treatment with antibiotics or probiotics for bacterial vaginosis (BV) is associated with a change in the diversity of vaginal microbiota in women was investigated. One hundred fifteen women, consisting of 30 healthy subjects, 30 BV-positive control subjects, 30 subjects with BV treated with a 7-day metronidazole regimen, and 25 subjects with BV treated with a 10-day probiotics regimen, were analyzed to determine the efficacy and disparity of diversity and richness of vaginal microbiota using 454 pyrosequencing. Follow-up visits at days 5 and 30 showed a greater BV cure rate in the probiotics-treated subjects (88.0 and 96 %, respectively) compared to the metronidazole-treated subjects (83.3 and 70 %, respectively [p = 0.625 at day 5 and p?=?0.013 at day 30]). Treatment with metronidazole reduced the taxa diversity and eradicated most of the BV-associated phylotypes, while probiotics only suppressed the overgrowth and re-established vaginal homeostasis gradually and steadily. Despite significant interindividual variation, the microbiota of the actively treated groups or participants constituted a unique profile. Along with the decrease in pathogenic bacteria, such as Gardnerella, Atopobium, Prevotella, Megasphaera, Coriobacteriaceae, Lachnospiraceae, Mycoplasma, and Sneathia, a Lactobacillus-dominated vaginal microbiota was recovered. Acting as vaginal sentinels and biomarkers, the relative abundance of Lactobacillus and pathogenic bacteria determined the consistency of the BV clinical and microbiologic cure rates, as well as recurrent BV. Both 7-day intravaginal metronidazole and 10-day intravaginal probiotics have good efficacy against BV, while probiotics maintained normal vaginal microbiota longer due to effective and steady vaginal microbiota restoration, which provide new insights into BV treatment.

    Vulvovaginal candidiasis (VVC) is one of the most prevalent vaginal infectious diseases, and there are controversial reports regarding the diversity of the associated vaginal microbiota. We determined the vaginal microbial community in patients with VVC, bacterial vaginosis (BV), and mixed infection of VVC and BV using Illumina sequencing of 16S rRNA tags. Our results revealed for the first time the highly variable patterns of the vaginal microbiome from VVC patients. In general, the alpha-diversity results of species richness and evenness showed the following order: normal control < VVC only < mixed BV and VVC infection < BV only. The beta-diversity comparison of community structures also showed an intermediate composition of VVC between the control and BV samples. A detailed comparison showed that, although the control and BV communities had typical patterns, the vaginal microbiota of VVC is complex. The mixed BV and VVC infection group showed a unique pattern, with a relatively higher abundance of Lactobacillus than the BV group and higher abundance of Prevotella, Gardnerella, and Atopobium than the normal control. In contrast, the VVC-only group could not be described by any single profile, ranging from a community structure similar to the normal control (predominated with Lactobacillus) to BV-like community structures (abundant with Gardnerella and Atopobium). Treatment of VVC resulted in inconsistent changes of the vaginal microbiota, with four BV/VVC samples recovering to a higher Lactobacillus level, whereas many VVC-only patients did not. These results will be useful for future studies on the role of vaginal microbiota in VVC and related infectious diseases. PMID:24265786

    A rat model of endometriosis, in which pieces of uterine horn (versus fat in controls) are autotransplanted into the abdomen where they form cysts, reduces fecundity and produces vaginal hyperalgesia. The cysts gradually enlarge over a 2-month period postsurgically and then plateau. Cysts regress with low estrogen levels and reappear when they rise. Based on the hypothesis that the vaginal hyperalgesia depends upon the cysts, this study tested two predictions: that (1) the hyperalgesia would develop postsurgically in parallel with the cysts, and (2) the hyperalgesia would vary with estrous, being greatest when estrogen levels are high (proestrus) and least when low (estrus). In rats trained to escape vaginal distention, percentage escape responses to different distention volumes were measured across the rat's 4-day estrous cycle for 2.5 months before and up to 4 months after autotransplantation of uterus (n=9) or fat (n=6) in abdominal sites. Vaginal pressures were also measured. In rats with uterine but not fat autotransplants, escape percentages increased postsurgically over a 2-month period and then plateaued. The increase was greatest in proestrus and failed to occur in estrus. Vaginal pressures were unchanged in all groups. These results strongly support the hypothesis that the vaginal hyperalgesia depends upon the cysts. Because the cysts were located in sites remote from the vagina, the hyperalgesia involves viscero-visceral interactions and is likely centrally mediated, whereas the estrous modulation could involve hormonal actions either on the cysts or, more likely, on vaginal afferent fibers, and/or on central neurons.

    INTRODUCTION This study aimed to determine and compare the effects of garlic tablets (Garcin®) and fluconazole on Candida vaginitis in women who presented to a health centre in Koohdasht, Iran, from August 2011 to March 2012. METHODS The clinical trial was conducted on 110 married women (aged 18–44 years) who had complaints of itching or a burning sensation in the vaginal area. Candida vaginitis was diagnosed by pH measurement of vaginal secretions, direct microscopic evaluation and Sabouraud dextrose agar cultures of the vaginal discharge. On confirmation of diagnosis, the patients were randomly divided into two groups (n = 55). One group received 1,500 mg of Garcin tablets daily and the other received fluconazole tablets 150 mg daily, over a period of seven days. Four to seven days after the completion of treatment, patients were examined for treatment response and possible side effects. RESULTS Complaints related to the disease improved by about 44% in the Garcin group and 63.5% in the fluconazole group (p < 0.05). The overall symptoms of the disease (i.e. redness of vulva and vagina, cheesy discharge, pustulopapular lesions and abnormal cervix) improved by about 60% in the Garcin group and 71.2% in the fluconazole group (p > 0.05). Results of microscopic evaluation and vaginal discharge culture showed significant differences before and after intervention in both groups (p < 0.05). CONCLUSION The present study shows that Garcin tablets could be a suitable alternative to fluconazole for the treatment of Candida vaginitis. PMID:26512149

    While many virulence factors promoting Streptococcus pyogenes invasive disease have been described, specific streptococcal factors and host properties influencing asymptomatic mucosal carriage remain uncertain. To address the need for a refined model of prolonged S. pyogenes asymptomatic mucosal colonization, we have adapted a preestrogenized murine vaginal colonization model for S. pyogenes. In this model, derivatives of strains HSC5, SF370, JRS4, NZ131, and MEW123 established a reproducible, asymptomatic colonization of the vaginal mucosa over a period of typically 3 to 4 weeks' duration at a relatively high colonization efficiency. Prior treatment with estradiol prolonged streptococcal colonization and was associated with reduced inflammation in the colonized vaginal epithelium as well as a decreased leukocyte presence in vaginal fluid compared to the levels of inflammation and leukocyte presence in non-estradiol-treated control mice. The utility of our model for investigating S. pyogenes factors contributing to mucosal carriage was verified, as a mutant with a mutation in the transcriptional regulator catabolite control protein A (CcpA) demonstrated significant impairment in vaginal colonization. An assessment of in vivo transcriptional activity in the CcpA? strain for several known CcpA-regulated genes identified significantly elevated transcription of lactate oxidase (lctO) correlating with excessive generation of hydrogen peroxide to self-lethal levels. Deletion of lctO did not impair colonization, but deletion of lctO in a CcpA? strain prolonged carriage, exceeding even that of the wild-type strain. Thus, while LctO is not essential for vaginal colonization, its dysregulation is deleterious, highlighting the critical role of CcpA in promoting mucosal colonization. The vaginal colonization model should prove effective for future analyses of S. pyogenes mucosal colonization. PMID:23460515

    The majority of HIV-1 infections in women occur through vaginal intercourse, in which virus-containing semen is deposited on the cervico-vaginal mucosa. Semen is more than a mere carrier of HIV-1, since it contains many biological factors, in particular cytokines, that may affect HIV-1 transmission. The concentration of interleukin (IL)-7, one of the most prominent cytokines in semen of healthy individuals, is further increased in semen of HIV-1-infected men. Here, we investigated the potential role of IL-7 in HIV-1 vaginal transmission in an ex vivo system of human cervico-vaginal tissue. We simulated an in vivo situation by depositing HIV-1 on cervico-vaginal tissue in combination with IL-7 at concentrations comparable with those measured in semen of HIV-1-infected individuals. We found that IL-7 significantly enhanced virus replication in ex vivo infected cervico-vaginal tissue. Similarly, we observed an enhancement of HIV-1 replication in lymphoid tissue explants. Analysis of T cells isolated from infected tissues showed that IL-7 reduced CD4+ T cell depletion preventing apoptosis, as shown by the decrease in the number of cells expressing the apoptotic marker APO2.7 and the increase in the expression of the anti-apoptotic protein B-cell lymphoma (Bcl)-2. Also, IL-7 increased the fraction of cycling CD4+ T cells, as evidenced by staining for the nuclear factor Ki-67. High levels of seminal IL-7 in vivo may be relevant to the survival of the founder pool of HIV-1-infected cells in the cervico-vaginal mucosa at the initial stage of infection, promoting local expansion and dissemination of HIV infection.

    The study of canine vaginal cytology underwent limited evolution over the years. Presence and significance of inflammatory cells in vaginal smears are little considered aspects in the bitch. Moreover, occurrence of vaginal bacteria in breeding bitches during follicular phase of the reproductive cycle, in absence of clinical signs of infection, involves the difficult question of antibiotics administration. The aim of this study was to relate findings in vaginal cytology (presence of neutrophils, lymphocytes, eosinophils, erytrocytes and bacteria) and microbial environment during proestrus with fertility outcomes (development of pregnancy, uterine infection, resorption, abortion and neonatal mortality). Bacteria sensitivity to antibiotics normally used in small animal practice was also evaluated. Bacteria isolated from vagina, in order of frequency, were Enterococcus faecalis, Streptococcus β-haemolyticus, Pasteurella multocida, E. coli, Klebsiella pneumoniae, Proteus mirabilis, E. coli haemolyticus, Arcanobacterium pyogenes, Streptococcus spp., Staphylococcus spp. and Acinetobacter spp. No mycoplasmas were observed. The present study showed that proestrous cytological aspects do not affect fertility. Eosinophils were never detected, while erythrocytes were always detected. During diestrus, E. coli was found in all pregnant bitches that developed clinical symptoms of uterine disorders (n = 3), resulting in uterine infection, resorption or abortion, but without statistical significance. Vaginal presence of Streptococcus spp. in proestrus was instead negatively associated with development of uterine infections (P = 0.005). Therefore, Streptococcus spp. could have a protective competitive role against more dangerous pathogens affecting fertility of the bitch. Among the 12 antibiotics tested, Gram-negative bacteria showed a significant sensitivity towards the amoxicillin and clavulanic acid association (P = 0.038). However, antibiotic treatment before mating, on the basis of positive culture, yet in the absence of clinical signs, seems to be unnecessary besides harmful leading to imbalance in vaginal commensal flora with adverse effects on fertility. In conclusion, vaginal bacteria, neutrophils, lymphocytes and erytrocytes should be considered as physiological aspect in the bitch during proestrus that does not require antibiotic therapy when asymptomatic.

    Women often develop vaginal infections that are caused primarily by organisms of the genus Candida. The current treatments of vaginal candidiasis usually involve azole-based antifungals, though fungal resistance to these compounds has become prevalent. Therefore, much attention has been given to molecules with antifungal properties from natural sources, such as curcumin (CUR). However, CUR has poor solubility in aqueous solvents and poor oral bioavailability. This study attempted to overcome this problem by developing, characterizing, and evaluating the in vitro antifungal action of a CUR-loaded liquid crystal precursor mucoadhesive system (LCPM) for vaginal administration. A low-viscosity LCPM (F) consisting of 40% wt/wt polyoxpropylene-(5)-polyoxyethylene-(20)-cetyl alcohol, 50% wt/wt oleic acid, and 10% wt/wt chitosan dispersion at 0.5% with the addition of 16% poloxamer 407 was developed to take advantage of the lyotropic phase behavior of this formulation. Notably, F could transform into liquid crystal systems when diluted with artificial vaginal mucus at ratios of 1:3 and 1:1 (wt/wt), resulting in the formation of F30 and F100, respectively. Polarized light microscopy and rheological studies revealed that F behaved like an isotropic formulation, whereas F30 and F100 behaved like an anisotropic liquid crystalline system (LCS). Moreover, F30 and F100 presented higher mucoadhesion to porcine vaginal mucosa than F. The analysis of the in vitro activity against Candida albicans revealed that CUR-loaded F was more potent against standard and clinical strains compared with a CUR solution. Therefore, the vaginal administration of CUR-loaded LCPMs represents a promising platform for the treatment of vaginal candidiasis. PMID:26257519

    Vaginal tablets are being developed as an alternative to gels as an inexpensive, discreet dosage form for the administration of microbicides. This work describes the pharmacokinetic (PK) evaluation of rapidly disintegrating vaginal tablets containing tenofovir (TFV, 10 mg), emtricitabine (FTC, 10 mg), and the combination of TFV and FTC (10 mg each) under in vitro and in vivo conditions, and in direct comparison to the clinical TFV 1% gel, a microbicide product in Phase III clinical testing. The PK of TFV and FTC from tablets were also evaluated in female rabbits following intravaginal administration. Direct comparison of a single dose of TFV tablets (intact or predissolved at 10 mg/mL) and TFV 1% gel showed no differences in the vaginal PK of TFV between groups; however systemic bioavailability of TFV was significantly higher from the gel. When rabbits were dosed either once or daily for seven days with intact tablets of TFV, FTC, or the combination of TFV/FTC, vaginal and systemic concentrations of TFV and FTC were unaffected by co-formulation. Moreover, plasma PK parameters were similar following a single dose or seven once-daily doses. Tissue concentrations of TFV and FTC in the cranial vagina 4 h after administration ranged between 104 and 105 ng/g. Concentrations of TFV-diphospate (TFV-DP, the active metabolite) were also high (over 103 ng/g or about 3000 to 6000 fmol/mg) in the cranial vagina 4 h after administration and similar to those measured following administration of TFV 1% gel. These data demonstrate that rapidly disintegrating vaginal tablets may be a suitable topical microbicide dosage form providing similar vaginal TFV PK to that of TFV 1% gel. The data also support co-administration of FTC with TFV in a single vaginal tablet to create a combination microbicide in a simple and inexpensive dosage form. PMID:25494201

    Background: Our purpose was to provide the clinical advantages of the laparoscopic approach compare to the vaginal approach in correcting uterine and vaginal vault prolapse. Methods: Between June 2007 and June 2011, 174 women were admitted to HUMC (Hallym University Medical Center) and underwent pelvic reconstructive surgery for prolapsed vaginal vault and uterus. Upon retrospective review of the medical records, 174 of the patients who had symptoms of pelvic organ prolapsed and Baden-Walker prolapse grade ≥ 2 were selected and divided into two groups as follows: vaginal approach group (n=120) and laparoscopic approach group (n=54). We compared the results of clinical outcome by analyzing Student's t-test and χ2-test or the Fisher exact test as appropriate. Results: There were significant difference in success rates without reoperation for recurrence as 91.7% (vaginal approach group, n=110) vs 100% (laparoscopic approach group, n=54), p=0.032. Mean follow-up duration was 31.3 ± 7.6 months for vaginal approach group and 29.7 ± 9.7 months for laparoscopic approach group. The Foley catheter indwelling duration (4.7± 1.9 vs 3.4±2.1 days, p< 0.001) and the length of postoperative hospitalization (6.4 ± 2.1 vs 5.0 ± 1.9 days, p <0.001) were significantly longer in vaginal approach group, whereas the operative time was significantly longer (108.2 ± 38.6 vs 168.3 ± 69.7 minutes, p <0.001) in laparoscopic approach group. Conclusions: Our result suggest there is significantly lower recurrence rate requiring reoperation and less catheterization time but increased operative time for laparascopic sacrocolpopexy.

    Vaginal tablets are being developed as an alternative to gels as an inexpensive, discreet dosage form for the administration of microbicides. This work describes the pharmacokinetic (PK) evaluation of rapidly disintegrating vaginal tablets containing tenofovir (TFV, 10 mg), emtricitabine (FTC, 10 mg), and the combination of TFV and FTC (10 mg each) under in vitro and in vivo conditions, and in direct comparison to the clinical TFV 1% gel, a microbicide product in Phase III clinical testing. The PK of TFV and FTC from tablets were also evaluated in female rabbits following intravaginal administration. Direct comparison of a single dose of TFV tablets (intact or predissolved at 10 mg/mL) and TFV 1% gel showed no differences in the vaginal PK of TFV between groups; however systemic bioavailability of TFV was significantly higher from the gel. When rabbits were dosed either once or daily for seven days with intact tablets of TFV, FTC, or the combination of TFV/FTC, vaginal and systemic concentrations of TFV and FTC were unaffected by co-formulation. Moreover, plasma PK parameters were similar following a single dose or seven once-daily doses. Tissue concentrations of TFV and FTC in the cranial vagina 4 h after administration ranged between 104 and 105 ng/g. Concentrations of TFV-diphospate (TFV-DP, the active metabolite) were also high (over 103 ng/g or about 3000 to 6000 fmol/mg) in the cranial vagina 4 h after administration and similar to those measured following administration of TFV 1% gel. These data demonstrate that rapidly disintegrating vaginal tablets may be a suitable topical microbicide dosage form providing similar vaginal TFV PK to that of TFV 1% gel. The data also support co-administration of FTC with TFV in a single vaginal tablet to create a combination microbicide in a simple and inexpensive dosage form. PMID:25494201

    Bacterial vaginosis (BV) is a dysbiosis of the vaginal flora characterized by a shift from a Lactobacillus-dominant environment to a polymicrobial mixture including Actinobacteria and Gram-negative bacilli. BV is a common vaginal condition in women and is associated with increased risk of sexually transmitted infection and adverse pregnancy outcomes such as preterm birth. Gardnerella vaginalis is one of the most frequently isolated bacterial species in BV. However, there has been much debate in the literature concerning the contribution of G. vaginalis to the etiology of BV, since it is also present in a significant proportion of healthy women. Here we present a new murine vaginal infection model with a clinical isolate of G. vaginalis. Our data demonstrate that this model displays key features used clinically to diagnose BV, including the presence of sialidase activity and exfoliated epithelial cells with adherent bacteria (reminiscent of clue cells). G. vaginalis was capable of ascending uterine infection, which correlated with the degree of vaginal infection and level of vaginal sialidase activity. The host response to G. vaginalis infection was characterized by robust vaginal epithelial cell exfoliation in the absence of histological inflammation. Our analyses of clinical specimens from women with BV revealed a measureable epithelial exfoliation response compared to women with normal flora, a phenotype that, to our knowledge, is measured here for the first time. The results of this study demonstrate that G. vaginalis is sufficient to cause BV phenotypes and suggest that this organism may contribute to BV etiology and associated complications. This is the first time vaginal infection by a BV associated bacterium in an animal has been shown to parallel the human disease with regard to clinical diagnostic features. Future studies with this model should facilitate investigation of important questions regarding BV etiology, pathogenesis and associated complications. PMID:23527214

    Background: Mycoplasma hominis and Ureaplasma urealyticum are important causative agents of vaginitis, cervicitis, postpartum sepsis, reproductive infections and infertility in both males and females. Objectives: According to the uncertain prevalence of U. urealyticum and M. hominis in Iranian infertile females, the present study was carried out to determine the prevalence of U. urealyticum and M. hominis in high vaginal swab samples of fertile and infertile females. Patients and Methods: A total of 350 high vaginal swab specimens were taken from fertile and infertile females. Samples were cultured and those that were positive for bacteria were subjected to the polymerase chain reaction (PCR) for further confirmation. Results: Of the 350 collected samples, eleven were positive for M. hominis (3.14%), fifteen were positive for U. urealyticum (4.28%) and five were positive for both of them (1.42%). Prevalence of U. urealyticum and M. hominis in the high vaginal parts of infertile females was higher than fertile females (P < 0.05). The results of traditional method were also confirmed, using the PCR amplification of urease gene of U. urealyticum and 16SrRNA gene of the M. hominis. Ureaplasma urealyticum and M. hominis had a higher prevalence in the high vaginal samples collected during the summer season. Conclusions: Considerable prevalence of M. hominis and U. urealyticum in the high vaginal swab samples of infertile females compared to the low prevalence in fertile females may suggest that these two pathogens can be cause infertility. Application of the PCR method is recommended for rapid and sensitive detection of M. hominis and U. urealyticum in high vaginal swab samples. PMID:26756000

    Women often develop vaginal infections that are caused primarily by organisms of the genus Candida. The current treatments of vaginal candidiasis usually involve azole-based antifungals, though fungal resistance to these compounds has become prevalent. Therefore, much attention has been given to molecules with antifungal properties from natural sources, such as curcumin (CUR). However, CUR has poor solubility in aqueous solvents and poor oral bioavailability. This study attempted to overcome this problem by developing, characterizing, and evaluating the in vitro antifungal action of a CUR-loaded liquid crystal precursor mucoadhesive system (LCPM) for vaginal administration. A low-viscosity LCPM (F) consisting of 40% wt/wt polyoxpropylene-(5)-polyoxyethylene-(20)-cetyl alcohol, 50% wt/wt oleic acid, and 10% wt/wt chitosan dispersion at 0.5% with the addition of 16% poloxamer 407 was developed to take advantage of the lyotropic phase behavior of this formulation. Notably, F could transform into liquid crystal systems when diluted with artificial vaginal mucus at ratios of 1:3 and 1:1 (wt/wt), resulting in the formation of F30 and F100, respectively. Polarized light microscopy and rheological studies revealed that F behaved like an isotropic formulation, whereas F30 and F100 behaved like an anisotropic liquid crystalline system (LCS). Moreover, F30 and F100 presented higher mucoadhesion to porcine vaginal mucosa than F. The analysis of the in vitro activity against Candida albicans revealed that CUR-loaded F was more potent against standard and clinical strains compared with a CUR solution. Therefore, the vaginal administration of CUR-loaded LCPMs represents a promising platform for the treatment of vaginal candidiasis. PMID:26257519

    Objective To use a biomechanical model to explore how impairment of the pubovisceral portion of the levator ani muscle and/or the apical vaginal suspension might interact to affect anterior vaginal wall prolapse severity. Method A biomechanical model of the anterior vaginal wall and its support system was developed and implemented. The anterior vaginal wall and main muscular and connective tissue support elements, namely the levator plate, pubovisceral muscle, cardinal and uterosacral ligaments, were included and their geometry based on mid-sagittal plane magnetic resonance scans. Material properties were based on published data. The change in the sagittal profile of the anterior vaginal wall during a maximum Valsalva was then simulated when different combinations of muscle and connective tissue impairment were present. Results Under raised intra-abdominal pressure, the magnitude of anterior vaginal wall prolapse was shown to be a combined function of both pubovisceral muscle and uterosacral and/or cardinal ligament (apical supports) impairment. Once a certain degree of pubovisceral impairment was reached, the genital hiatus opened and a prolapse developed. The larger the pubovisceral impairment, the larger the anterior wall prolapse became. A 90% impairment of apical support led to an increase in anterior wall prolapse from 0.3 cm to 1.9 cm (a 530% increase) at 60% pubovisceral muscle impairment, and from 0.7 cm to 2.4 cm (a 240% increase) at 80% pubovisceral muscle impairment. Conclusions These results suggest that a prolapse can develop as a result of impairment of the muscular and apical supports of the anterior vaginal wall. PMID:16880302

    Phase I pharmacokinetic (PK) study assessed circulating estrogens in breast cancer (BC) patients on a non-steroidal aromatase inhibitor (NSAI) with vaginal atrophy using vaginal ultra-low-dose 0.03 mg estriol (E3) and Lactobacillus combination vaginal tablets (Gynoflor(®)). 16 women on NSAI with severe vaginal atrophy applied a daily vaginal tablet of Gynoflor(®) for 28 days followed by a maintenance therapy of 3 tablets weekly for 8 weeks. Primary outcomes were serum concentrations and PK of E3, estradiol (E2), and estrone (E1) using highly sensitive gas chromatography-mass spectrometry. Secondary outcomes were clinical measures for efficacy and side effects; microscopic changes in vaginal epithelium and microflora; and changes in serum FSH, LH, and sex hormone-binding globulin. Compared with baseline, serum E1 and E2 did not increase in any of the women at any time following vaginal application. Serum E3 transiently increased after the first application in 15 of 16 women, with a maximum of 168 pg/ml 2-3 h post-insertion. After 4 weeks, serum E3 was slightly increased in 8 women with a maximum of 44 pg/ml. The vaginal atrophy resolved or improved in all women. The product was well tolerated, and discontinuation of therapy was not observed. The low-dose 0.03 mg E3 and Lactobacillus acidophilus vaginal tablets application in postmenopausal BC patients during AI treatment suffering from vaginal atrophy lead to small and transient increases in serum E3, but not E1 or E2, and therefore can be considered as safe and efficacious for treatment of atrophic vaginitis in BC patients taking NSAIs.

    Capsomers were produced in bacteria as glutathione-S-transferase (GST) fusion proteins with human papillomavirus type 16 L1 lacking the first nine and final 29 residues (GST-HPV16L1Δ) alone or linked with residues 13–47 of HPV18, HPV31 and HPV45 L2 in tandem (GST-HPV16L1Δ-L2x3). Subcutaneous immunization of mice with GST-HPV16L1Δ or GST-HPV16L1Δ-L2x3 in alum and monophosphoryl lipid A induced similarly high titers of HPV16 neutralizing antibodies. GST-HPV16L1Δ-L2x3 also elicited moderate L2-specific antibody titers. Intravaginal challenge studies showed that immunization of mice with GST-HPV16 L1Δ or GST-HPV16L1Δ-L2x3 capsomers, like Cervarix®, provided complete protection against HPV16. Conversely, vaccination with GST-HPV16 L1Δ capsomers failed to protect against HPV18 challenge, whereas mice immunized with either GST-HPV16L1Δ-L2x3 capsomers or Cervarix® were each completely protected. Thus, while the L2-specific response was moderate, it did not interfere with immunity to L1 in the context of GST-HPV16L1Δ-L2x3 and is sufficient to mediate L2-dependent protection against an experimental vaginal challenge with HPV18.

    Objective To study the relationship between fetal station and successful vaginal delivery in nulliparous women. Study Design This was a secondary analysis from a previously reported trial of pulse oximetry. Vaginal delivery rates were evaluated and compared with respect to the fetal station. Spontaneous labor and induction of labor groups were evaluated separately. Multivariable logistic regression analysis was performed to adjust for confounding factors. Results Successful vaginal delivery was more frequent with an engaged vertex for spontaneous labor (86.2% versus 78.6%; p = 0.01) and induced labor (87.7% versus 66.1%; p < 0.01). After adjustment, engaged fetal vertex was not associated with vaginal delivery for spontaneous labor (odds ratio [OR] 1.5; 95% confidence interval [CI] 0.95 to 2.3; p = 0.08) or for women with induced labor (OR 2.2; 95% CI 0.96 to 5.1; p = 0.06). Conclusion Among nulliparous women enrolled in the FOX randomized trial in spontaneous labor or for labor induction, an engaged fetal vertex does not affect their vaginal delivery rate.

    Objectives To determine whether assessment of all moderate-to-severe symptoms at baseline gives a more accurate evaluation of the treatment effect of ospemifene in vulvovaginal atrophy (VVA) than the most bothersome symptom (MBS) approach. Methods Data were pooled from two pivotal phase-III clinical trials evaluating the efficacy and safety of oral ospemifene 60?mg/day for the treatment of symptoms of VVA (n?=?1463 subjects). Symptoms of vaginal dryness, dyspareunia, and vaginal and/or vulvar irritation/itching reported as moderate or severe at baseline were evaluated. Clinically relevant differences between ospemifene and placebo were analyzed using a four-point severity scoring system and presented as improvement, substantial improvement, or relief. Results Subjects in these studies reported statistically significant improvement, substantial improvement, and relief for vaginal dryness (p?vaginal and/or vulvar irritation/itching (p?vaginal and/or vulvar irritation/itching. Conclusions For drug registration purposes, the use of the MBS model is appealing because of its simplicity and ease of scientific validation. However, the MBS model may underestimate the total magnitude of the clinical benefit of ospemifene treatment for symptomatic women suffering from VVA. PMID:26669628

    Streptococcus agalactiae (Group B Streptococcus, GBS) is a Gram-positive bacterium, which colonizes the vaginal tract in 10-30% of women. Colonization is transient in nature, and little is known about the host and bacterial factors controlling GBS persistence. Gaining insight into these factors is essential for developing therapeutics to limit maternal GBS carriage and prevent transmission to the susceptible newborn. In this work, we have used human cervical and vaginal epithelial cells, and our established mouse model of GBS vaginal colonization, to characterize key host factors that respond during GBS colonization. We identify a GBS strain that persists beyond a month in the murine vagina, whereas other strains are more readily cleared. Correspondingly, we have detected differential cytokine production in human cell lines after challenge with the persistent strain vs. other GBS strains. We also demonstrate that the persistent strain more readily invades cervical cells compared with vaginal cells, suggesting that GBS may potentially use the cervix as a reservoir to establish long-term colonization. Furthermore, we have identified interleukin-17 production in response to long-term colonization, which is associated with eventual clearance of GBS. We conclude that both GBS strain differences and concurrent host immune responses are crucial in modulating vaginal colonization. PMID:25850655

    Purpose To determine the efficacy and complications of adjuvant vaginal high-dose-rate brachytherapy alone for patients with Stage I endometrial cancer in whom complete surgical staging had been performed. Methods and Materials Between April 1998 and March 2004, 100 patients with Stage I endometrial cancer underwent surgical staging (total abdominal hysterectomy and bilateral salpingo-oophorectomy with pelvic {+-} paraaortic nodal sampling) and postoperative vaginal high-dose-rate brachytherapy at our institution. The total dose was 2100 cGy in three fractions. Results With a median follow-up of 23 months (range 2-62), no pelvic or vaginal recurrences developed. All patients underwent pelvic dissection, and 42% underwent paraaortic nodal dissection. A median of 29.5 pelvic nodes (range 1-67) was removed (84% had >10 pelvic nodes removed). Most patients (73%) had endometrioid (or unspecified) adenocarcinoma, 16% had papillary serous carcinoma, and 11% had other histologic types. The International Federation of Gynecology and Obstetrics stage and grade was Stage IA, grade III in 5; Stage IB, grade I, II, or III in 6, 27, or 20, respectively; and Stage IC, grade I, II, or III in 13, 17, or 10, respectively. The Common Toxicity Criteria (version 2.0) complications were mild (Grade 1-2) and consisted primarily of vaginal mucosal changes, temporary urinary irritation, and temporary diarrhea. Conclusion Adjuvant vaginal high-dose-rate brachytherapy alone may be a safe and effective alternative to pelvic external beam radiotherapy for surgical Stage I endometrial cancer.

    Carcinoma of the endometrium is the most common malignancy of the female genital tract. In early stage endometrial cancer, surgery remains the primary mode of treatment while radiation therapy plays an adjuvant role. Prophylactic vaginal radiation has been shown to reduce significantly the incidence of vaginal recurrences. Between the years 1969-1976, 330 patients with FIGO Stages I and II endometrial cancer were treated according to a standard departmental policy in which 40 Gy of external radiation was given to high risk Stage I and II patients in combination with surgery and intravaginal radiation. With this regimen, the mucosal surface received a total equivalent dose of 40 Gy. These treatments were given on an outpatient basis without the need for any sedation or analgesics. The minimum follow-up was 5 years, with a median follow-up of 8.5 years. The overall pelvic and/or vaginal recurrence rate was 2.7%. The incidence of vaginal complications was 3.7%. The advantages of a remote after loading technique in delivering vaginal vault radiation in endometrial cancer are discussed.

    A high dose rate ({sup 60}Co) afterloading technique was used for postoperative prophylactic vaginal irradiation in a series of 404 women with endometrial carcinoma Stage I. The total recurrence rate was 3.7% with 0.7% vaginal deposits. The crude 5-year survival rate for the complete series was 91.8% compared to 13.3% for those with recurrences. Depth of myometrial infiltration (greater than 1/3 of the uterine wall) and nuclear grade were the most important prognostic factors. Clinically significant late radiation reactions (bladder and/or rectum) were recorded in 6.9%. Dose per fraction and the size of the target volume were highly significantly related to the occurrence of both early and late radiation reactions. Vaginal shortening is closely related to the dose per fraction, length of the reference isodose, and the applicator diameter. The shape of the vaginal applicator versus the isodoses and the importance of the source train geometry and relative activity for dose gradient inhomogeneities within the target volume are discussed. Cumulative radiation effect (CRE) and linear-quadratic (LQ) calculations have been performed and related to tissue reactions within the target volume and in the risk organs. An alpha-beta quotient of 8.8 for vaginal shrinkage effect and 2.0 for late rectal complications are suggested on the basis of calculations using a maximum likelihood method for quantal radiation data.

    Sustained growth in primary culture of vaginal epithelial cells from ovariectomized adult BALB/cCrg1 mice embedded within or seeded on collagen gel matrix was achieved in a serum-free medium composed of Ham's F-12 medium/Dulbecco's modified Eagle's medium, 1:1 (vol/vol), supplemented with insulin, bovine serum albumin fraction V, epidermal growth factor, cholera toxin, and transferrin. Three-dimensional growth of vaginal epithelial cells occurred inside the collagen gel matrix. Cell numbers increased 4- to 8-fold in collagen gel and about 4-fold on collagen gel after 9-10 days in culture. The effect of 17β -estradiol (0.00018-180 nM in gel or 0.018-180 nM on gel) and diethylstilbestrol (DES; 0.0186-186 nM in gel) on the growth of vaginal epithelial cells was examined. The addition of estrogen did not enhance the growth of vaginal epithelial cells during this time period either in the complete medium or in a suboptimal medium. Cultures on floating collagen gels in the serum-free medium are composed of 1-3 cell layers with superficial cornification. Estrogen does not appear to be a direct mitogen for vaginal epithelial cells, at least in this system.

    Vaginal delivery of active drugs has been largely studied for local and systemic applications. It is well known that vagina is a complex route, due to physiological and non-physiological changes. Therefore, in order to achieve a prolonged local effect, these variations have to be considered. The aim of this study was to formulate and to characterize a solid system, called sponges, obtained by lyophilization of cellulosic derivative (HEC 250M) hydrogels. These sponges have to meet particular criteria to be adapted for vaginal application: they have to adhere to the vaginal cavity and to be rehydrated by the small amount of vaginal fluids. Moreover, they have to be easily manipulated and to be stable. Three freezing temperatures have been tested to prepare sponges (-15C, -25C, -35C). By SEM analyzes, it was observed that the pores into the sponges were smaller and numerous as the freezing temperature decreases. However, this temperature did not have any influence on the rehydration speed that was rather influenced by the HEC concentration. Viscosity and mucoadhesive strength of hydrogels and corresponding sponges were also measured. It appeared that these parameters are mainly dependent on the HEC concentration. These mucoadhesive sponges can be considered as potential drug delivery systems intended for vaginal application. PMID:25660908

    Summary Streptococcus agalactiae (Group B Streptococcus, GBS) is a frequent commensal organism of the vaginal tract of healthy women. However, GBS can transition to a pathogen in susceptible hosts, but host and microbial factors that contribute to this conversion are not well understood. GBS CovR/S (CsrR/S) is a two component regulatory system that regulates key virulence elements including adherence and toxin production. We performed global transcription profiling of human vaginal epithelial cells exposed to WT, CovR deficient, and toxin deficient strains, and observed that insufficient regulation by CovR and subsequent increased toxin production results in a drastic increase in host inflammatory responses, particularly in cytokine signaling pathways promoted by IL-8 and CXCL2. Additionally, we observed that CovR regulation impacts epithelial cell attachment and intracellular invasion. In our mouse model of GBS vaginal colonization, we further demonstrated that CovR regulation promotes vaginal persistence, as infection with a CovR deficient strain resulted in a heightened host immune response as measured by cytokine production and neutrophil activation. Using CXCr2 KO mice, we determined that this immune alteration occurs, at least in part, via signaling through the CXCL2 receptor. Taken together, we conclude that CovR is an important regulator of GBS vaginal colonization and loss of this regulatory function may contribute to the inflammatory havoc seen during the course of infection.

    This paper presents results from the first UK national survey of patient information and interventions related to vaginal dilation in pelvic radiotherapy (RT). The aim was to elicit current practice with regard to the target population, content/process of patient education, and the evaluation of compliance in relation to this intervention. A 38-item questionnaire was sent to all RT departments (n= 65) and a convenience sample of specialist gynecological oncology nurses (n= 166), with response rates of 62% (n= 40) and 31% (n= 52), respectively. Data analysis (via SPSS v11) used both descriptive and inferential statistics. Divergence of opinion was evident regarding the specific target audience for dilator education, and only a limited number of elements of vaginal dilator technique achieved consensus. Sixty-seven percent of respondents stated they carried out a wider sexual health assessment associated with the provision of dilator information, although its content varied considerably. Results suggest the provision of vaginal dilation advice may benefit from being placed in the wider context of assessing treatment impact on women's sexual health, raising the profile of appropriate psychosexual assessment, and intervention in clinical oncology practice. Further research could determine the efficacy of vaginal dilation in preventing development of vaginal stenosis among women receiving pelvic RT. PMID:16803497

    In five studies, the advantage of repeated vaginal prophylaxis by a new preparation of hexetidine vaginal suppositories (10 mg) was investigated prospectively, randomised and method-controlled (n = 2 x 50). After a five-day application, the hexetidine group achieved bacterial reductions of five log CFU/ml in the vagina and nearly three log CFU/ml in the cervix uteri, whilst no reduction was found in the controls at any time (p less than 0.01). The reduction of individual bacterial species was investigated in 224 pregnant and also gynaecological patients. In cases of impending preterm childbirth, a five-day application of 20 mg hexetidine/day could reduce all bacteria sufficiently with the exception of lactobacilli; especially beta Streptococci were reduced. The same was achieved by a three-day application of 10 mg hexetidine/day pre-operatively. A long-term study in 11,724 deliveries showed, that neonatal infectious mortality and morbidity after 36 gestational weeks could be reduced significantly by hexetidine. The new hexetidine preparation appeared to be efficient in vaginal antisepsis, especially in pregnancy. A favourable lactobacilli-selective effect was demonstrated. Since the importance of lactobacilli in vaginal ecology is known, hexetidine prophylaxis must be considered as advantageous in Obstetrics and Gynecology. From a practical and economic point of view, the application of hexetidine as vaginal suppositories appears favourable compared to antiseptic solutions. PMID:1773929

    Chemical attenuation of the reactive oxygen species (ROS)-sensitive anaerobes Trichomonas vaginalis, which is the most prevalent non-viral sexually transmitted infection, and two often coexisting vaginal infections, namely Candida albicans and Staphylococcus aureus, which are opportunistic reproductive tract infections, was attempted with novel ammonium salts of carbamodithioic acid through inhibition of free thiols. In vitro and in vivo efficacies of the designed compounds were evaluated as topical vaginal microbicides. Five compounds showed exceptional activity against drug-resistant and -susceptible strains with negligible toxicity to host (HeLa) cells in vitro in comparison with the standard vaginal microbicide nonoxynol-9 (N-9), without disturbing the normal vaginal flora (i.e. Lactobacillus). The compounds significantly inhibited the cytopathic effects of Trichomonas on HeLa cells in vitro with efficacies comparable with metronidazole (MTZ); however, their efficacy to rescue host cells from co-infection (protozoal and fungal) was greater than that of MTZ. The compounds inhibited ?-haemolysis of red blood cells caused by Trichomonas and were found to be active in vivo in the mouse subcutaneous abscess assay. Some compounds rapidly immobilized human sperm. A mechanism involving inhibition of free thiols and consequently the cysteine proteases of T. vaginalis by the new compounds has been proposed. Thus, a unique scaffold of antimicrobial agents has been discovered that warrants further investigation for development as contraceptive vaginal microbicides. PMID:26706422

    The effects of intravaginal administration of dehydroepiandrosterone (DHEA) for the management of symptomatic vulvovaginal atrophy are reviewed. A literature search related to vulvovaginal atrophy, vaginal atrophy, atrophic vaginitis, estrogen, dehydroepiandrosterone, vulvar itching, burning, dryness, dyspareunia, and libido was performed. Relevant articles addressing the incidence, management, and outcome of DHEA therapy were identified and used for this Expert Opinion. DHEA compared to a placebo is an effective treatment improving symptoms of vaginal atrophy: dyspareunia, burning, itching, and dryness. Objective parameters of vaginal atrophy, specifically pH, vaginal maturation index (VMI), and investigator-evaluated changes in the vagina: moisture, epithelia integrity and color were improved compared to baseline and placebo. There were significant improvements in libido and dyspareunia with the intravaginal use of DHEA that contribute to improved quality of life for postmenopausal women. Dehydroepiandrosterone administered intravaginally on a daily basis is an effective treatment for symptoms, and signs of vulvovaginal atrophy along with libido in postmenopausal women. This article is part of a Special Issue entitled 'Essential role of DHEA'. PMID:25201455

    We examined consistency in self-reports of age at first vaginal sex among 9,399 male and female respondents who participated in Waves III and IV (separated by approximately 7 years) of the National Longitudinal Study of Adolescent Health (Add Health). Respondents were coded as consistent if they reported an age at first vaginal intercourse at Wave IV that was within 1 year of the age they reported at Wave III. Sociodemographic, behavioral, and cognitive predictors of consistency were examined using bivariate and multivariate logistic regression. Overall, 85.43% of respondents were able to provide consistent reports. Among both males and females, consistency was associated with age, years since first vaginal intercourse, race/ethnicity, and lifetime number of other-sex partners in final multivariate models. Respondents who were older and had more recently had their first sexual experience were more likely to be consistent. For females only, those who reported a history of non-parental, physically forced sex were less likely to be consistent. Most young adults consistently report age at first vaginal intercourse, supporting the credibility of retrospective self-reports about salient sexual events such as timing of first vaginal intercourse.

    Bacterial vaginosis (BV) is a common vaginal disorder characterized by the decrease of lactobacilli and overgrowth of Gardnerella vaginalis and resident anaerobic vaginal bacteria. In the present work, the effects of rifaximin vaginal tablets on vaginal microbiota and metabolome of women affected by BV were investigated by combining quantitative PCR and a metabolomic approach based on (1)H nuclear magnetic resonance. To highlight the general trends of the bacterial communities and metabolomic profiles in response to the antibiotic/placebo therapy, a multivariate statistical strategy was set up based on the trajectories traced by vaginal samples in a principal component analysis space. Our data demonstrated the efficacy of rifaximin in restoring a health-like condition in terms of both bacterial communities and metabolomic features. In particular, rifaximin treatment was significantly associated with an increase in the lactobacillus/BV-related bacteria ratio, as well as with an increase in lactic acid concentration and a decrease of a pool of metabolites typically produced by BV-related bacteria (acetic acid, succinate, short-chain fatty acids, and biogenic amines). Among the tested dosages of rifaximin (100 and 25 mg for 5 days and 100 mg for 2 days), 25 mg for 5 days was found to be the most effective. PMID:24709255

    Abstract Objectives To determine whether assessment of all moderate-to-severe symptoms at baseline gives a more accurate evaluation of the treatment effect of ospemifene in vulvovaginal atrophy (VVA) than the most bothersome symptom (MBS) approach. Methods Data were pooled from two pivotal phase-III clinical trials evaluating the efficacy and safety of oral ospemifene 60 mg/day for the treatment of symptoms of VVA (n = 1463 subjects). Symptoms of vaginal dryness, dyspareunia, and vaginal and/or vulvar irritation/itching reported as moderate or severe at baseline were evaluated. Clinically relevant differences between ospemifene and placebo were analyzed using a four-point severity scoring system and presented as improvement, substantial improvement, or relief. Results Subjects in these studies reported statistically significant improvement, substantial improvement, and relief for vaginal dryness (p < 0.00001), dyspareunia (p < 0.001) and statistically significant improvement and relief for vaginal and/or vulvar irritation/itching (p < 0.01) from baseline to week 12 with ospemifene compared with placebo. A similar trend was observed for women who reported substantial improvement of vaginal and/or vulvar irritation/itching. Conclusions For drug registration purposes, the use of the MBS model is appealing because of its simplicity and ease of scientific validation. However, the MBS model may underestimate the total magnitude of the clinical benefit of ospemifene treatment for symptomatic women suffering from VVA. PMID:26669628

    We examined the community ecology of vaginal microbial samples taken from pregnant women with previous preterm birth experience to investigate whether targeted pathogenic and commensal bacteria are related to risk of preterm birth in the current pregnancy. We found a significant correlation between the community structure of selected bacteria and birth outcome, but the correlation differed among self-reported racial/ethnic groups. Using a community ordination analysis, we observed infrequent co-occurrence of Mycoplasma and bacteria vaginosis associated bacteria 3 (BVAB3) among black and Hispanic participants. In addition, we found that the vaginal bacteria responded differently in different racial/ethnic groups to modifications of maternal behavioral (ie, douching and smoking) and biological traits (ie, body mass index [BMI]). Even after accounting for these maternal behaviors and traits, the selected vaginal bacteria was significantly associated with preterm birth among black and Hispanic participants. By contrast, white participants did not exhibit significant correlation between microbial community and birth outcome. Findings from this study affirm the necessity of considering women's race/ethnicity when evaluating the correlation between vaginal bacteria and preterm birth. The study also illustrates the importance of studying the vaginal microbiota from an ecological perspective, and demonstrates the power of ecological community analysis to improve understanding of infectious disease.

    The aim of this work was to develop a synbiotic vaginal insert containing the probiotic strain Lactobacillus crispatus BC5, the prebiotic substrate fructo-oligosaccharide and the antioxidant agent ascorbic acid, for the prophylaxis and therapy of vaginal infections. Mucoadhesive in situ gelling vaginal inserts based on hydroxypropyl methylcellulose were prepared by freeze-drying, stored at +2-8C for 90 days and characterized in terms of technological and functional properties. Complete survival of L. crispatus BC5 was found immediately after insert preparation (96.08%) as well as after 90 days of storage (95.82%) in the vaginal inserts containing fructo-oligosaccharide, ascorbic acid and skimmed milk. Synbiotic inserts showed improved mucoadhesion ability (from three- to five-fold) with respect to a standard formulation based on hydroxypropyl methylcellulose alone. Moreover, inserts allowed to modulate lactobacilli release in virtue of the different amounts of fructo-oligosaccharide. Finally, antimicrobial activity was exerted by L. crispatus BC5 released from the vaginal formulation. PMID:26572459

    Effect of Zataria multiflora on bacterial vaginosis and Trichomonas vaginalis is shown in vivo and in vitro. We compare the effectiveness of Zataria multiflora cream and oral metronidazole pill on results of treatment for vaginal infections including Trichomonas and bacterial vaginosis; these infections occur simultaneously. The study included 420 women with bacterial vaginosis, Trichomonas vaginalis, or both infections together, who were randomly divided into six groups. Criteria for diagnosis were wet smear and Gram stain. Vaginal Zataria multiflora cream and placebo pill were administered to the experiment groups; the control group received oral metronidazole pill and vaginal placebo cream. Comparison of the clinical symptoms showed no significant difference in all three vaginitis groups receiving metronidazole pill and vaginal Zataria multiflora cream. However, comparison of the wet smear test results was significant in patients with trichomoniasis and bacterial vaginosis associated with trichomoniasis in the two treatment groups (p = 0.001 and p = 0.01). Vaginal Zataria multiflora cream had the same effect of oral metronidazole tablets in improving clinical symptoms of all three vaginitis groups, as well as the treatment for bacterial vaginosis. It can be used as a drug for treatment of bacterial vaginosis and elimination of clinical symptoms of Trichomonas vaginitis. PMID:26266260

    We have explored the use of optical coherence tomography (OCT) as a noninvasive tool for assessing the toxicity of topical microbicides, products used to prevent HIV, by monitoring the integrity of the vaginal epithelium. A novel feature-based segmentation algorithm using a nearest-neighbor classifier was developed to monitor changes in the morphology of vaginal epithelium. The two-step automated algorithm yielded OCT images with a clearly defined epithelial layer, enabling differentiation of normal and damaged tissue. The algorithm was robust in that it was able to discriminate the epithelial layer from underlying stroma as well as residual microbicide product on the surface. This segmentation technique for OCT images has the potential to be readily adaptable to the clinical setting for noninvasively defining the boundaries of the epithelium, enabling quantifiable assessment of microbicide-induced damage in vaginal tissue.

    Women's initial understandings and anticipated acceptability of long-acting vaginal gels as potential anti-HIV microbicides was investigated by exploring the perceptibility variables associated with prototype formulations. Four focus groups with 29 women, aged 18-45, were conducted to consider gel prototypes with varied physicochemical and rheological properties. Participants responded favorably to the concept of long-acting vaginal gels as microbicides. Distinctions in understandings and stated needs regarding product dosing, characteristics, and effectiveness offer valuable insights into product design. Long-acting vaginal gels capable of protecting against HIV/STIs will be a viable option among potential users, with dosing frequency being an important factor in willingness to use. PMID:24248674

    The aim of this study was to prepare and evaluate the mucoadhesive, biocompatible and biodegradable progesterone containing vaginal tablets based on modified starch copolymers for the estrus synchronization of ewes. Starch-graft-poly(acrylic acid) copolymers (S-g-PAA) were synthesized and characterized. The vaginal tablets were fabricated with S-g-PAA and their equilibrium swelling degree (Qe) and matrix erosion (ME%) were determined in lactate buffer solution. In vitro, mucoadhesive properties of the tablets were investigated by using ewe vaginal mucosa and in vivo residence time were also investigated. In vitro and in vivo progesterone release profiles from the tablets were compared with two commercial products. Tablet formulation containing wheat starch based grafted copolymer (WS-g-PAA)gc indicated promising results and might be convenient as an alternative product to the commercial products in veterinary medicine.

    The purpose of this study is to determine predictive factors of successful vaginal delivery after cesarean section, and to estimate the risks of this trial of labor (TOL). A retrospective study about 352 women undergoing a TOL after cesarean section was carried out. Different variables stratified by the termination of the TOL were analysed with statistic tests. TOL success rate was 76.1%. Parity > or = 3. prior vaginal delivery following cesarean section, body mass index < 30, fundal height < 34 cm, and low fetal head level at the beginning of labor increased significantly the probability of success. Uterine rupture rate is 1.1%. Failure of TOL was associated with a higher risk of uterine scar dehiscence and rupture, and higher fetal morbidity. A predictive score of successful vaginal delivery after cesarean section is proposed. PMID:16634207

    Vulvar varicosities are generally not an indication for a caesarean section but in a rare case of severe vulvar varicosities, it would be a controversial issue whether to perform a caesarean section for fear they might rupture during a vaginal delivery. We present a case of huge vulvar varicosities during pregnancy. MRI revealed obstruction of the internal iliac system by the gravid uterus and subsequent incompetence of a collateral pathway via the round ligament vein that emptied into the ovarian vein. The patient went into labour at 38 weeks, and successfully vaginally delivered a baby. The vulvar varicose veins became compressed by the foetal head from the inside, and markedly diminished in size during crowning and after delivery. Women with vulvar varicosities can be allowed to attempt a vaginal birth regardless of their severity. The use of MRI aids in the overall anatomical understanding of vulvar varicosities in pregnancy.

    In recent years, surgical treatment of stress urinary incontinence has become minimally invasive owing to the introduction of the transobturator route first and then single incision devices for positioning of mid-urethral slings. Although a number of case reports in the literature describe pregnancies successfully terminated both by vaginal delivery and cesarean section following mid-urethral sling positioning, there is still no definitive consensus on which is the preferred mode of delivery in these patients. We report a case of spontaneous vaginal delivery at term in a 41-year-old multiparous woman two years after the positioning of a single incision sling (TVT-Secur). The patient remained continent throughout the gestation and in the following 24?months. This case seems to further support the concept that sling procedures for stress urinary incontinence do not represent an absolute contraindication to spontaneous vaginal delivery, although the preferred mode of delivery must be assessed on an individual basis.

    Vaginal epithelium is colonized by different bacterial strains and species. The bacterial composition of vaginal biofilms controls the balance between health and disease. Little is known about the relative contribution of the epithelial and bacterial cell surfaces to bacterial adhesion and whether and how adhesion is regulated over cell membrane regions. Here, we show that bacterial adhesion forces with cell membrane regions not located above the nucleus are stronger than with regions above the nucleus both for vaginal pathogens and different commensal and probiotic lactobacillus strains involved in health. Importantly, adhesion force ratios over membrane regions away from and above the nucleus coincided with the ratios between numbers of adhering bacteria over both regions. Bacterial adhesion forces were dramatically decreased by depleting the epithelial cell membrane of cholesterol or sub-membrane cortical actin. Thus, epithelial cells can regulate membrane regions to which bacterial adhesion is discouraged, possibly to protect the nucleus. PMID:26477544

    The knowledge of the effects of antimicrobial agents on the normal vaginal microflora is limited. The objective of the present study was to study the ecological impact of pivmecillinam on the normal vaginal microflora. In 20 healthy women, the estimated day of ovulation was determined during three subsequent menstrual cycles. Microbiological and clinical examinations were performed on the estimated day of ovulation and on day 3 in all cycles and also on day 7 after ovulation in cycles 1 and 2. Anaerobic and facultative anaerobic gram-positive rods, mainly species of lactobacilli and actinomycetes, dominated the microflora. One woman was colonized on the third day of administration with a resistant Escherichia coli strain, and Candida albicans was detected in one woman on days 3 and 7 in cycle 2. No other major changes in the normal microflora occurred during the study. Administration of pivmecillinam had a minor ecological impact on the normal vaginal microflora. PMID:15616292

    Concentrations of serum estradiol-17? and progesterone were monitored in six female walruses using an enzyme immunoassay. Progesterone concentrations increased from March to May in females aged 6 y or older, and subsequently declined (October). No significant elevation of estradiol-17? concentration was detected before an elevation of progesterone concentration. Vaginal smears from four females were examined with Papanicolaou staining. In all females, most epithelial cells were basophilic intermediate-superficial cells; no color change from basophilic to eosinophilic of the cells was detected. Meanwhile, the percentage of anucleate cells in vaginal smears reached its highest value before the elevation of progesterone concentration, followed by an increase in the percentage of leukocytes. We inferred that the change in populations of anucleate cells and leukocytes in vaginal smears reflected ovarian status and CL formation in female walruses. PMID:22153266

    Lactobacilli are found in a wide variety of habitats. Four species, Lactobacillus crispatus, L. gasseri, L. iners, and L. jensenii, are common and abundant in the human vagina and absent from other habitats. These may be adapted to the vagina and possess characteristics enabling them to thrive in that environment. Furthermore, stable codominance of multiple Lactobacillus species in a single community is infrequently observed. Thus, it is possible that individual vaginal Lactobacillus species possess unique characteristics that confer to them host-specific competitive advantages. We performed comparative functional genomic analyses of representatives of 25 species of Lactobacillus, searching for habitat-specific traits in the genomes of the vaginal lactobacilli. We found that the genomes of the vaginal species were significantly smaller and had significantly lower GC content than those of the nonvaginal species. No protein families were found to be specific to the vaginal species analyzed, but some were either over- or underrepresented relative to nonvaginal species. We also found that within the vaginal species, each genome coded for species-specific protein families. Our results suggest that even though the vaginal species show no general signatures of adaptation to the vaginal environment, each species has specific and perhaps unique ways of interacting with its environment, be it the host or other microbes in the community. These findings will serve as a foundation for further exploring the role of lactobacilli in the ecological dynamics of vaginal microbial communities and their ultimate impact on host health.

    Overactive bladder (OAB) and vaginal dryness are common problems after menopause. Oxybutynin (OXY) is an antimuscarinic agent that has been available for more than 30 years in the treatment of OAB patients. The aim of the work reported in this paper was to develop long acting mucoadhesive gel formulations of OXY and to investigate their effects on blood levels compared to those of oral OXY immediate release tablets, in rabbits. Mucoadhesive gels were prepared with chitosan, hydroxypropyl methylcellulose (HPMC K100M) and Poloxamer 407 (Pluronic F 127). The physicopharmaceutical properties of gels were evaluated. The gel formulation which was prepared with HPMC K100M, exhibited the highest viscosity, the greatest adhesiveness, cohesiveness and mucoadhesion values. The formulation which was prepared from HPMC K100M showed suitable permeation characteristics across the vaginal mucosa. Comparative bioavailability studies were carried out on rabbits with vaginal HPMC gel, vaginal chitosan gel, vaginal OXY solution and commercially available oral ropan tablets. It was concluded that the highest AUC and relative bioavailability values were obtained for the bioadhesive vaginal gel formulation prepared with HPMC K100M. Therefore, the mucoadhesive vaginal gels of OXY can be a promising and innovative alternative therapeutic system for the treatment of OAB. It can be safely used in cases of overactive bladder and as well as vaginal dryness after menopause. PMID:24036011

    Background Cervical priming agents mainly prostaglandins in different doses and routes are used during first trimester vaccum aspiration to prevent cervical injury and shorten the abortion procedure. This study was carried out to assess women's acceptability, the efficacy and side effects of oral versus vaginal administration of misoprostol in facilitating cervical dilatation prior to first trimester vaccum aspiration. Methods A randomised control study where 120 women were divided in oral (51) and vaginal (69) group. Each group received 400mcg of misoprostol either orally or vaginally 04h prior to first trimester pregnancy termination. Baseline cervical dilatation, women's acceptability and side effects and complications were noted in both the groups. Results There was no difference between the oral and vaginal misoprostol groups with respect to mean cervical dilatation (5.53mm vs 5.43mm; p>0.05). A total of 88% of women in the oral group expressed satisfaction with the route of misoprostol administration as compared to 74% in the vaginal route. The women in the vaginal group were experienced more preoperative vaginal bleeding (43% vs 25%). Conclusion Oral administration of misoprostol is an effective alternative to vaginal administration in preinduction cervical ripening prior to first trimester pregnancy termination. PMID:24532930

    In the European Union the use of anabolic hormones in meat production is forbidden since 1988 and this ban of anabolic agents in animal production is strictly controlled. New hormone cocktails passing the detection systems are attractive for the practice and so new approaches to discover their illegal use have to be developed steadily. Verifying physiological effects caused by anabolic steroids will be a new way to develop potential monitoring systems. One promising matrix in female animals will be vaginal smear containing vaginal epithelial cells, because the vaginal epithelium is a primary steroid hormone responsive organ. In this study we quantified the gene expression in vaginal smear of sexually mature cattle in order to observe physiological effects. Further we aimed to establish a new screening method by testing the effect of a combination of certain anabolic steroid hormones on physiological regulations of mRNA expression of selected genes. In an animal trial Nguni heifers were treated with the anabolic combination trenbolone acetate plus estradiol. Vaginal smear samples were taken at 4 different time points. Gene expression of 27 candidate genes, selected by screening the actual literature for steroidal effects on vaginal epithelial cells, were estimated using quantitative real-time RT-PCR. There were different expression changes observed at different time points. It could be shown that the applied anabolic combination significantly influenced the expression of the steroid receptor ER?, the keratinization factor CK8, the proinflammatory interleukins IL-1? and IL-1?, the growth factors FGF7, EGF, EGFR, IGF-1R, TGF? and LTF, the oncogen c-jun and other factors like actin? and ubiquitin 3. Using biostatistical tools like principal components analysis or hierarchical cluster analysis, the potential to develop a gene expression pattern for targeting the illegal use of growth promoters could be demonstrated.

    Background Bacterial vaginosis (BV) is a common condition, although its aetiology remains unexplained. The aim of this study was to analyse the composition of vaginal microbiota in women from Greenland to provide a quantitative description and improve the understanding of BV. Methods Self-collected vaginal smears and swabs were obtained from 177 women. The vaginal smears were graded for BV according to Nugent’s criteria. The vaginal swab samples were analysed by 19 quantitative PCRs (qPCRs) for selected vaginal bacteria and by PCR for four sexually transmitted infections (STIs). Results STIs were common: Mycoplasma genitalium 12%, Chlamydia trachomatis 7%, Neisseria gonorrhoeae 1%, and Trichomonas vaginalis 0.5%. BV was found in 45% of women, but was not associated with individual STIs. Seven of the 19 vaginal bacteria (Atopobium vaginae, Prevotella spp., Gardnerella vaginalis, BVAB2, Eggerthella-like bacterium, Leptotrichia amnionii, and Megasphaera type 1) had areas under the receiver operating characteristic (ROC) curve > 85%, suggesting they are good predictors of BV according to Nugent. Prevotella spp. had the highest odds ratio for BV (OR 437; 95% CI 82–2779) in univariate analysis considering only specimens with a bacterial load above the threshold determined by ROC curve analysis as positive, as well as the highest adjusted odds ratio in multivariate logistic regression analysis (OR 4.4; 95% CI 1.4-13.5). BV could be subdivided into clusters dominated by a single or a few species together. Conclusions BV by Nugent score was highly prevalent. Two of seven key species (Prevotella spp. and A. vaginae) remained significantly associated with BV in a multivariate model after adjusting for other bacterial species. G. vaginalis and Prevotella spp. defined the majority of BV clusters. PMID:24131550

    Women of European ancestry are more likely to harbour a Lactobacillus-dominated microbiome, whereas African American women are more likely to exhibit a diverse microbial profile. African American women are also twice as likely to be diagnosed with bacterial vaginosis and are twice as likely to experience preterm birth. The objective of this study was to further characterize and contrast the vaginal microbial profiles in African American versus European ancestry women. Through the Vaginal Human Microbiome Project at Virginia Commonwealth University, 16S rRNA gene sequence analysis was used to compare the microbiomes of vaginal samples from 1268 African American women and 416 women of European ancestry. The results confirmed significant differences in the vaginal microbiomes of the two groups and identified several taxa relevant to these differences. Major community types were dominated by Gardnerella vaginalis and the uncultivated bacterial vaginosis-associated bacterium-1 (BVAB1) that were common among African Americans. Moreover, the prevalence of multiple bacterial taxa that are associated with microbial invasion of the amniotic cavity and preterm birth, including Mycoplasma, Gardnerella, Prevotella and Sneathia, differed between the two ethnic groups. We investigated the contributions of intrinsic and extrinsic factors, including pregnancy, body mass index, diet, smoking and alcohol use, number of sexual partners, and household income, to vaginal community composition. Ethnicity, pregnancy and alcohol use correlated significantly with the relative abundance of bacterial vaginosis-associated species. Trends between microbial profiles and smoking and number of sexual partners were observed; however, these associations were not statistically significant. These results support and extend previous findings that there are significant differences in the vaginal microbiome related to ethnicity and demonstrate that these differences are pronounced even in healthy women.

    Human papillomavirus (HPV) is the most important causative agent of cervical cancers worldwide. However, our understanding of how the vaginal microbiota might be associated with HPV infection is limited. In addition, the influence of human genetic and physiological factors on the vaginal microbiota is unclear. Studies on twins and their families provide the ideal settings to investigate the complicated nature of human microbiota. This study investigated the vaginal microbiota of 68 HPV-infected or uninfected female twins and their families using 454-pyrosequencing analysis targeting the variable region (V2-V3) of the bacterial 16S rRNA gene. Analysis of the vaginal microbiota from both premenopausal women and HPV-discordant twins indicated that HPV-positive women had significantly higher microbial diversity with a lower proportion of Lactobacillus spp. than HPV-negative women. Fusobacteria, including Sneathia spp., were identified as a possible microbiological marker associated with HPV infection. The vaginal microbiotas of twin pairs were significantly more similar to each other than to those from unrelated individuals. In addition, there were marked significant differences from those of their mother, possibly due to differences in menopausal status. Postmenopausal women had a lower proportion of Lactobacillus spp. and a significantly higher microbiota diversity. This study indicated that HPV infection was associated with the composition of the vaginal microbiota, which is influenced by multiple host factors such as genetics and menopause. The potential biological markers identified in this study could provide insight into HPV pathogenesis and may represent biological targets for diagnostics. PMID:23717441

    The application of high-throughput sequencing methods has raised doubt in the concept of the uniform healthy vaginal microbiota consisting predominantly of lactobacilli by revealing the existence of more variable bacterial community composition. As this needs to be analyzed more extensively and there is little straightforward data regarding the vaginal mycobiome of asymptomatic women we aimed to define bacterial and fungal communities in vaginal samples from 494 asymptomatic, reproductive-age Estonian women. The composition of the vaginal microbiota was determined by amplifying bacterial 16S rRNA and fungal internal transcribed spacer-1 (ITS-1) regions and subsequently sequencing them using 454 Life Sciences pyrosequencing. We delineated five major bacterial community groups with distinctive diversity and species composition. Lactobacilli were among the most abundant bacteria in all groups, but also members of genus Gardnerella had high relative abundance in some of the groups. Microbial diversity increased with higher vaginal pH values, and was also higher when a malodorous discharge was present, indicating that some of the women who consider themselves healthy may potentially have asymptomatic bacterial vaginosis (BV). Our study is the first of its kind to analyze the mycobiome that colonizes the healthy vaginal environment using barcoded pyrosequencing technology. We observed 196 fungal operational taxonomic units (OTUs), including 16 OTUs of Candida spp., which is more diverse than previously recognized. However, assessing true fungal diversity was complicated because of the problems regarding the possible air-borne contamination and bioinformatics used for identification of fungal taxons as significant proportion of fungal sequences were assigned to unspecified OTUs.

    Background In prior work, children born to mothers who received neuraxial anesthesia for cesarean delivery had a lower incidence of subsequent learning disabilities compared with vaginal delivery. The authors speculated that neuraxial anesthesia may reduce stress responses to delivery, which could affect subsequent neurodevelopmental outcomes. To further explore this possibility, we examined the association between the use of neuraxial labor analgesia and development of childhood learning disabilities in a population-based birth cohort of children delivered vaginally. Methods The educational and medical records of all children born to mothers residing in five townships of Olmsted County, MN from 1976-1982 and remaining in the community at age 5 years were reviewed to identify those with learning disabilities. Cox proportional hazards regression was used to compare the incidence of learning disabilities between children delivered vaginally with and without neuraxial labor analgesia, including analyses adjusted for factors of either potential clinical relevance or that differed between the two groups in univariate analysis. Results Of the study cohort, 4684 mothers delivered children vaginally, with 1495 receiving neuraxial labor analgesia. The presence of childhood learning disabilities in the cohort was not associated with use of labor neuraxial analgesia (adjusted hazard ratio 1.05, 95% C.I. 0.85 to 1.31, P = 0.63). Conclusion The use of neuraxial analgesia during labor and vaginal delivery was not independently associated with learning disabilities diagnosed before age 19 years. Future studies are needed to evaluate potential mechanisms of the previous finding indicating that the incidence of learning disabilities is lower in children born to mothers via cesarean delivery under neuraxial anesthesia compared to vaginal delivery.

    Objectives To explore clinically relevant differences in severity of vulvar and vaginal atrophy (VVA) in postmenopausal women treated with ospemifene compared with placebo. Methods Analysis of two multicenter, randomized, double-blind, 12-week phase-III studies in postmenopausal women (40–80 years, with VVA, treated with ospemifene 60 mg/day or placebo (Study 310 and Study 821)). Severity of vaginal dryness and dyspareunia were evaluated using a four-point scoring system and clinically relevant differences between ospemifene and placebo were analyzed and are presented as improvement (reduction in ≥ 1 unit on four-point scoring system), substantial improvement (reduction in 2–3 units on four-point scoring system) and relief (severity score of mild/none after 12 weeks). Results In Study 310, significantly more women with a most bothersome symptom of dyspareunia had improvement (68.3% vs. 54.1%; p = 0.0255) or relief (57.5% vs. 41.8%; p = 0.0205) in the severity of dyspareunia from baseline to week 12 with ospemifene compared with placebo. For those with a most bothersome symptom of vaginal dryness, significantly more experienced improvement (74.6% vs. 57.7%; p = 0.0101), substantial improvement (42.4% vs. 26.9%; p = 0.0172) and relief (66.1% vs. 49.0%; p = 0.0140) of vaginal dryness from baseline to week 12 with ospemifene compared with placebo. Proportions of women with improvement/substantial improvement/relief of symptoms of vaginal dryness or dyspareunia were similar in Study 821. Clinically relevant differences were noticeable by week 4. Conclusions Treatment with ospemifene was consistently associated with greater improvement, substantial improvement or relief in the severity of the most bothersome symptoms of vaginal dryness or dyspareunia compared with placebo.

    This article provides a knowledge-based assessment of planned cesarean delivery compared with planned vaginal delivery for breech presentation at term gestation. The most critical evidence on this issue is the intention-to-treat analysis from the Term Breech Trial, which showed that planned cesarean delivery reduced composite perinatal death and serious neonatal morbidity. Although there was no difference in composite death or neurodevelopmental delay at 2 years of age, this finding was based on only 44% of randomized patients and was not an analysis by intention to treat. On the other hand, the design of the nonexperimental Presentation et Mode d'Accouchement: presentation and mode of delivery (PREMODA) study (which showed no difference in composite perinatal mortality or morbidity after planned cesarean delivery compared with planned vaginal delivery), likely favored the planned vaginal delivery group; lack of exclusion criteria led to higher risk women (with contraindications to vaginal delivery) being included in the planned cesarean delivery group. Such selection bias notwithstanding, both the Term Breech Trial and the PREMODA study showed significantly higher rates of 5-minute Apgar score less than 4, 5-minute Apgar score less than 7, intubation, and birth trauma in the planned vaginal delivery group. Finally, studies from the Netherlands, Denmark, and Canada have shown that increases in planned cesarean delivery after the Term Breech Trial led to improved neonatal outcomes. Nevertheless, planned vaginal delivery continues to be associated with higher rates of adverse perinatal outcomes in these countries. The totality of the evidence therefore unequivocally shows the relatively greater safety of planned cesarean delivery for breech presentation at term gestation. PMID:25932844

    Background: Many factors have been mentioned to influence decision-making for different kinds of delivery. Decision-making for vaginal delivery is under the influence of culture, perceptions, beliefs, values, attitudes, personalities, and knowledge. The current study aims at exploring the determinants of decision-making for vaginal delivery in the north of Iran from women's perspective. Materials and Methods: A focused ethnographic method with purposeful sampling method has been used. Semi-structured interviews and observation were conducted with 12 pregnant women and 10 delivered women, 7 midwives, 7 gynecologists, and 9 non-pregnant women in Tonekabon clinics. Interviews and observations were recorded and transcribed. The accuracy of the extracted codes and themes was confirmed by restoration of the arranged and coded texts to the participants (member check) and by an expert person from outside the study context. Data were analyzed using thematic analysis and MAXqda software. Results: Five themes were extracted from the data: Economic influencing factors, Cultural values and norms related to normal childbirth, Positive attitudes towards vaginal delivery, Role of important others, and Facilitators of natural birth. Several sub-themes and sub-sub themes also emerged from the data (e.g. safe delivery, forming maternal feelings, painful but tolerable, maternal role facilitator, inexpensive delivery, a process with good outcome and less complications, relief messenger). Conclusions: Giving enough information about vaginal delivery for pregnant women and their family members, training pregnant women to increase tolerance during labor pain, and modifying expenses can increase economic affordability, positive cultural norms and attitudes about vaginal delivery, proper social support, use of normal delivery facilitators, and direct them toward vaginal delivery.

    The human body is colonized by a vast number of microorganisms collectively referred to as the human microbiota. One of the main microbiota body sites is the female genital tract, commonly dominated by Lactobacillus spp., in approximately 70% of women. Each individual species can constitute approximately 99% of the ribotypes observed in any individual woman. The most frequently isolated species are Lactobacillus crispatus, Lactobacillus gasseri, Lactobacillus jensenii and Lactobacillus iners. Residing at the port of entry of bacterial and viral pathogens, the vaginal Lactobacillus species can create a barrier against pathogen invasion since mainly products of their metabolism secreted in the cervicovaginal fluid can play an important role in the inhibition of bacterial and viral infections. Therefore, a Lactobacillus-dominated microbiota appears to be a good biomarker for a healthy vaginal ecosystem. This balance can be rapidly altered during processes such as menstruation, sexual activity, pregnancy and various infections. An abnormal vaginal microbiota is characterized by an increased diversity of microbial species, leading to a condition known as bacterial vaginosis. Information on the vaginal microbiota can be gathered from the analysis of cervicovaginal fluid, by using the Nugent scoring or the Amsel's criteria, or at the molecular level by investigating the number and type of Lactobacillus species. However, when translating this to the clinical setting, it should be noted that the absence of a Lactobacillus-dominated microbiota does not appear to directly imply a diseased condition or dysbiosis. Nevertheless, the widely documented beneficial role of vaginal Lactobacillus species demonstrates the potential of data on the composition and activity of lactobacilli as biomarkers for vaginal health. The substantiation and further validation of such biomarkers will allow the design of better targeted probiotic strategies. PMID:25859220

    The potent antiretroviral pyrimidinediones IQP-0528 (PYD1) and IQP-0532 (PYD2) were formulated in polyurethane intravaginal rings (IVRs) as prophylactic drug delivery systems to prevent the sexual transmission of HIV-1. To aid in the selection of a pyrimidinedione candidate and the optimal loading of the drug in the IVR delivery system, four pyrimidinedione IVR formulations (PYD1 at 0.5 wt% [PYD10.5wt%], PYD11wt%, PYD24wt%, and PYD214wt%) were evaluated in pigtail macaques over 28 days for safety and pyrimidinedione vaginal biodistribution. Kinetic analysis of vaginal proinflammatory cytokines, native microflora, and drug levels suggested that all formulations were safe, but only the high-loaded PYD214wt% IVR demonstrated consistently high pyrimidinedione vaginal fluid and tissue levels over the 28-day study. This formulation delivered drug in excess of 10 μg/ml to vaginal fluid and 1 μg/g to vaginal tissue, a level over 1,000 times the in vitro 50% effective concentration. The in vitro release of PYD1 and PYD2 under nonsink conditions correlated well with in vivo release, both in amount and in kinetic profile, and therefore may serve as a more biologically relevant means of evaluating release in vitro than typically employed sink conditions. Lastly, the pyrimidinediones in the IVR formulation were chemically stable after 90 days of storage at elevated temperature, and the potent nanomolar-level antiviral activity of both molecules was retained after in vitro release. Altogether, these results point to the successful IVR formulation and vaginal biodistribution of the pyrimidinediones and demonstrate the usefulness of the pigtail macaque model in evaluating and screening antiretroviral IVR formulations prior to preclinical and clinical evaluation.

    Non diethylstilbestrol induced vaginal adenosis has a reported incidence of about 10% in adult women. Although in some, it may be an insignificant coincidental finding, it is probably under-diagnosed even in symptomatic women. Little is known about the aetiology, pathogenesis, symptomatology and management of this poorly understood condition. Our experience with the four cases of vaginal adenosis unrelated to diethylstilbestrol (DES) exposure and a review of the literature will probably shed some light on this, as it still remains an enigma in gynaecological oncology.

    Vulvovaginal candidiasis (VVC) is an extremely common cause of vaginal symptoms in women. Multiple antifungal products are available by either the oral or vaginal route, although no new drugs have become available for two decades. Given the therapeutic equivalence of the antimycotic agents and their routes of administration, the specific drug and formulation selected is entirely arbitrary in relation to final treatment outcome. Nevertheless, multiple factors affecting preference, both practitioner-dependent and patient-dependent, impact on selection of a specific drug and route of administration. PMID:24368881

    We present a case of a 27-year-old women admitted to the hospital with migraine and left upper extremity weakness. Subsequent imaging with computed tomography and magnetic resonance angiography/venography demonstrated an acute-appearing central venous sinus thrombosis. Her only risk factor for venous thromboembolism (VTE) was the use of etonogestrel/ethinyl estradiol vaginal contraceptive ring (NuvaRing). The contraceptive ring was removed and the patient was treated according to the current guidelines. She achieved full neurologic recovery at 6 months' follow-up. Here, we describe this unusual case and review the risk of VTE between combined vaginal contraception and combined oral contraception. PMID:24477227

    The objective of this study was to compare complications and effectiveness of induction after vaginal and sublingual administration of misoprostol for labor induction in women with intra-uterine fetal death (IUFD). In a district hospital in Ghana, 23 women with IUFD who underwent labor induction with sublingual misoprostol were compared with a control group of 21 women who received vaginal misoprostol. In the vaginal group 28.6% had one or more complications compared to 21.7% in the sublingual group. In the sublingual group three inductions did not lead to delivery within 48 hours (13%), compared to four in the other group (19%). The mean induction-to-delivery time in the sublingual group was 13 hours and 17 hours in the vaginal group. In this study, both sublingual and vaginal misoprostol were safe and efficient for labor induction in women with IUFD. However, more research on larger numbers of patients is needed, in order to compare complications. PMID:20305098

    This study aimed to assess the prevalence of pathological vaginal discharge and to describe risk factors associated with pregnant women. All women living in the city of Rio Grande, Southern Brazil, who gave birth in 2010 were included in the study. A standardized questionnaire was administered to collect information on demographic, reproductive, and health-related factors and morbidity during pregnancy. The chi-square test was used to compare proportions, and multivariate Poisson regression with robust variance was performed. Of the 2,395 women studied, 43% had pathological vaginal discharge during pregnancy. The adjusted analysis showed that younger women of lower socioeconomic condition, those with a past history of abortion, vaginal discharge in a previous pregnancy, and treated for depression, anemia, and urinary tract infection during their current pregnancy, were more likely to have pathological vaginal discharge. Vaginal discharge during pregnancy was highly prevalent in the sample studied calling for proper risk factor management at the primary care level. PMID:23843798

    Menstrual toxic shock syndrome (mTSS) is a rare, recognizable, and treatable disease that has been associated with tampon use epidemiologically. It involves a confluence of microbial risk factors (Staphylococcus aureus strains that produce the superantigen-TSST-1), as well as environmental characteristics of the vaginal ecosystem during menstruation and host susceptibility factors. This paper describes a series of experiments using the well-characterized model of porcine vaginal mucosa ex-vivo to assess the effect of these factors associated with tampon use on the permeability of the mucosa. The flux of radiolabeled TSST-1 and tritiated water ((3)H2O) through porcine vaginal mucosa was determined at various temperatures, after mechanical disruption of the epithelial surface by tape stripping, after treatment with surfactants or other compounds, and in the presence of microbial virulence factors. Elevated temperatures (42, 47 and 52C) did not significantly increase flux of (3)H2O. Stripping of the epithelial layers significantly increased the flux of labeled toxin in a dose-dependent manner. Addition of benzalkonium chloride (0.1 and 0.5%) and glycerol (4%) significantly increased the flux of (3)H2O but sodium lauryl sulfate at any concentration tested did not. The flux of the labeled toxin was significantly increased in the presence of benzalkonium chloride but not Pluronic L92 and Tween 20 and significantly increased with addition of ?-hemolysin but not endotoxin. These results show that the permeability of porcine vagina ex-vivo to labeled toxin or water can be used to evaluate changes to the vaginal environment and modifications in tampon materials, and thus aid in risk assessment.

    Infections of the lower genital tract associated to maternal and perinatal complications frequently occur during pregnancy. The aim of this study was to evaluate vaginal dysfunction through the analysis of basic vaginal states (BVS) using the methodology of balance of the vaginal content (BAVACO) and to compare it with the microbiological study of candidiasis, trichomoniasis and bacterial vaginosis (BV). Pregnant patients (1238) were examined from 2010 to 2012. In asymptomatic (A) (n: 1046) and symptomatic pregnant women (S) (n: 192) BVS I was 59.5% and 26% of the patients, respectively. BVS II was observed in 19.7% of A and in 17.2% of S. BVS III was only detected in A in 0.4%. BVS IV was observed in 14.4% of A and in 38% of S. BVS V was detected in 6% of A and in 18.8% of S. Yeasts were associated to BVS I and II in 55.5% and 23.2% of A, respectively; and in 32.4% and 31% of S, respectively. Trichomonas were associated to BVS I in 50% of A, to IV in 44.4% of S and to V in 33.3% of S. BAVACO susceptibility to detect yeasts was 80.4% and 85.5% in A and S, respectively; 40% and 75% in A and S, respectively, to detect trichomonas and 100% in A and S to detect BV. BAVACO specificity was 100% for all pathogens in A and S. The study of BVS proved useful as a guide to evaluate vaginal dysfunction, regardless of symptomatology. Therefore, this study is recommended as prenatal control. PMID:25444125

    This in vitro study assessed the antimicrobial properties of a novel octasilver salt of Sucrose Octasulfate (IASOS) as well as of an innovative vaginal gel containing IASOS (SilSOS Femme), against bacterial and yeast pathogens isolated from human clinical cases of symptomatic vaginal infections. In BHI and LAPT culture media, different ionic silver concentrations and different pHs were tested. IASOS exerted a strong antimicrobial activity towards all the pathogens tested in both culture media. The results demonstrated that salts and organic compounds present in the culture media influenced IASOS efficacy only to a moderate extent. Whereas comparable MBCs (Minimal Bactericidal Concentrations) were observed for G. vaginalis (10 mg/L Ag+), E. coli and E. aerogenes (25 mg/L Ag+) in both media, higher MBCs were found for S. aureus and S. agalactiae in LAPT cultures (50 mg/L Ag+ versus 25 mg/L Ag+). No minimal concentration totally inhibiting the growth of C. albicans was found. Nevertheless, in both media at the highest ionic silver concentrations (50-200 mg/L Ag+), a significant 34-52% drop in Candida growth was observed. pH differently affected the antimicrobial properties of IASOS against bacteria or yeasts; however, a stronger antimicrobial activity at pH higher than the physiological pH was generally observed. It can be therefore concluded that IASOS exerts a bactericidal action against all the tested bacteria and a clear fungistatic action against C. albicans. The antimicrobial activity of the whole vaginal gel SilSOS Femme further confirmed the antimicrobial activity of IASOS. Overall, our findings support IASOS as a valid active ingredient into a vaginal gel. PMID:24897299

    Objective To develop a self-report questionnaire assessing the impact of vaginal dryness, soreness, itching, irritation, and pain on functioning and well-being in postmenopausal women. Methods Structured self-report items were developed to address the impact of vaginal symptoms on functioning and wellbeing based on findings from focus groups with racially/ethnically diverse, symptomatic postmenopausal women. Items were refined after cognitive interview pre-testing and then field-tested among symptomatic postmenopausal women enrolled in a multiethnic cohort study in California. Exploratory (SAS PROC VARCLUS) and confirmatory factor analyses evaluated factor structure and eliminate poorly fitting items. Additional evidence of construct validity was obtained via examination of correlations with other measures of related constructs. Internal consistency and test-re-test reliability were assessed using Cronbach’s alpha and correlation coefficients, respectively. Results Of the 745 postmenopausal women completing the draft questionnaire, mean (SD) age was 56.2 (8.5) years, and 66% were racial/ethnic minorities. The refined questionnaire included four multi-item scales addressing symptom impact on: 1) activities of daily living, 2) emotional well-being, 3) sexual functioning, and 4) self-concept and body image. The four factor model provided good approximate fit (comparative fit index = 0.987, standardized root-mean-square residual = 0.038). Correlations with other measures of symptom bothersomeness, sexual function, depression, and anxiety conformed to hypotheses. Cronbach’s alpha ranged from 0.82 to 0.93. Intra-class coefficients ranged from 0.47 to 0.72. Conclusions The Day-to-Day Impact of Vaginal Aging (DIVA) questionnaire is a new multidimensional self-report measure designed to facilitate evaluation of the impact of vaginal symptoms in postmenopausal women of diverse backgrounds.

    Mannose-binding lectin (MBL) is a recognition molecule of the complement (C) system and binds to carbohydrate ligands present on a wide range of pathogenic bacteria, viruses, fungi, and parasites. MBL has been detected in the cervico-vaginal cavity where it can provide a first-line defence against infectious agents colonizing the lower tract of the reproductive system. Analysis of the cervico-vaginal lavage (CVL) obtained from 11 normal cycling women at different phases of the menstrual cycle revealed increased levels of MBL in the secretive phase. Part of this MBL derives from the circulation as indicated by the presence of transferrin in CVL tested as a marker of vascular and tissue permeability. The local synthesis of MBL is suggested by the finding that its level is substantially higher than that of transferrin in the secretive phase. The contribution of endometrium is negligible since the MBL level did not change before and after hysterectomy. RT-PCR and in situ RT-PCR analysis showed that the vaginal tissue, and in particular the basal layer of the epithelium, is a source of MBL which binds to the basal membrane and to cells of the outer layers of the epithelium. In conclusion, we have shown that MBL detected in CVL derives both from plasma as result of transudation and from local synthesis and its level is progesterone dependent increasing in the secretive phase of the menstrual cycle.

    Purpose: Vaginal balloon packing is a means to displace organs at risk during high dose rate brachytherapy of the uterine cervix. We tested the hypothesis that contrast-filled vaginal balloon packing reduces radiation dose to organs at risk, such as the bladder and rectum, in comparison to water- or air-filled balloons. Methods and Materials: In a phantom study, semispherical vaginal packing balloons were filled with air, saline solution, and contrast agents. A high dose rate iridium-192 source was placed on the anterior surface of the balloon, and the diode detector was placed on the posterior surface. Dose ratios were taken with each material in the balloon. Monte Carlo (MC) simulations, by use of the MC computer program DOSXYZnrc, were performed to study dose reduction vs. balloon size and contrast material, including commercially available iodine- and gadolinium-based contrast agents. Results: Measured dose ratios on the phantom with the balloon radius of 3.4 cm were 0.922 {+-} 0.002 for contrast/saline solution and 0.808 {+-} 0.001 for contrast/air. The corresponding ratios by MC simulations were 0.895 {+-} 0.010 and 0.781 {+-} 0.010. The iodine concentration in the contrast was 23.3% by weight. The dose reduction of contrast-filled balloon ranges from 6% to 15% compared with water-filled balloon and 11% to 26% compared with air-filled balloon, with a balloon size range between 1.4 and 3.8 cm, and iodine concentration in contrast of 24.9%. The dose reduction was proportional to the contrast agent concentration. The gadolinium-based contrast agents showed less dose reduction because of much lower concentrations in their solutions. Conclusions: The dose to the posterior wall of the bladder and the anterior wall of the rectum can be reduced if the vaginal balloon is filled with contrast agent in comparison to vaginal balloons filled with saline solution or air.

  4. A Rabbit Vaginal Cell-Derived Antimicrobial Peptide, RVFHb?P, Blocks Lipopolysaccharide-Mediated Inflammation in Human Vaginal Cells In Vitro ?

    Antimicrobial peptides (AMPs) constitute a phylogenetically ancient form of innate immunity that provides host defense at various mucosal surfaces, including the vagina. Recently, we have identified one such AMP, rabbit vaginal fluid hemoglobin alpha peptide (RVFHb?P), from the vaginal lavage of rabbits (Oryctolagus cuniculus). The recent demonstration of a protective role of this peptide in erythrocytes and vaginal cells led us to investigate (i) the lipopolysaccharide (LPS) interactive domain in RVFHb?P and (ii) whether RVFHb?P of rabbit origin modulates the cellular immune responses of another species (humans) in vitro. HeLa-S3, a human vaginal epithelial cell line (hVEC), was exposed to LPS alone (10 ?g/ml for 6 h), or LPS-induced cells were treated with RVFHb?P (70.45 ?M for 1 h) and cultured for 24 h, and the results obtained were compared with the medium control. We show here that RVFHb?P exerts an anti-inflammatory activity in hVECs, as suggested by the prevention of LPS-induced production of extracellular (supernatant) and intracellular (lysate) levels of cytokines (interleukin 6 [IL-6] and IL-1?) and chemokines (IL-8 and monocyte chemoattractant protein 1 [MCP-1]). The demonstration of Toll-like receptor 4 (TLR4) and NF-?B expression in hVECs and the observations of RVFHb?P suppression of human ?-defensin-1 (hBD1) mRNA expression further support the hypothesis of a genomic activity of RVFHb?P. Confocal microscopy and flow cytometry results demonstrate that RVFHb?P inhibits LPS-induced phagocytosis of Escherichia coli by macrophages. The chemotaxis studies performed using the Boyden chamber Transwell method showed the increased migration of U937 cells when supernatants of LPS-induced hVECs were used, and this effect was inhibited by RVFHb?P. In conclusion, our study proposes a novel explanation for the protective role of RVFHb?P in inflammation-associated infections, which not only may provide the new cellular targets for the screening of RVFHb?P ligands acting in the vaginal tissue but also has the potential to develop RVFHb?P as a therapeutic agent for reproductive tract infections.

    Composition of the bacterial microbiome in the vagina and vestibule from 30 women with vulvar vestibulitis syndrome (VVS) and 15 healthy controls were compared by pyrosequencing 16S rRNA gene amplicons. Vaginal concentrations of interleukin (IL)-1? were determined by ELISA. Questionnaires elicited clinical and symptom data. Eighteen genera were detected in vaginal samples, and 23 genera were identified in vestibule samples, from women with VVS. The genera at both sites and the mean number of genera in subjects with VVS were largely similar to those in control subjects. However, differences were noted including higher proportions of Streptococcus and Enterococcus in women with VVS. Furthermore, Lactobacillus iners was more frequently identified in women with VVS while L.crispatus was more frequent in the control women. The dominant bacterial genera in the vagina closely paralleled the dominant genera present in the corresponding vestibular sample in both groups, leading us to postulate that vaginal secretions are an important source of bacteria present on the vestibule. Vaginal IL-1? levels were similar and varied depending on the dominant bacteria. We conclude in this pilot study that no major differences are apparent in the vagina and vestibule between women with or without VVS, except for an increased prevalence of Streptococcus and L. iners in some women with VVS.

    The aim of this study was to develop mucoadhesive and thermosensitive gels for vaginal delivery that would be able to provide a controlled release of the model drug, cidofovir. The study also monitored the drug's potential antiviral properties. Cidofovir was put into the form of a vaginal gel, using mucoadhesive and thermosensitive polymers such as chitosan, Carbopol 974P, HPMC, and poloxamer 407. The physicopharmaceutical properties and stability of the vaginal gel formulations were evaluated. The gel formulation which was prepared with HPMC K100M exhibited the highest viscosity, as well as maximum adhesiveness, cohesiveness, and mucoadhesion values. The results of antiviral activity studies, which used the bovine herpes virus type 1 virus infection in vitro model using Vero cells, demonstrated the antiherpetic effect of the cidofovir gel containing HPMC K100M, at least under in vitro conditions. The study found that a mucoadhesive vaginal gel containing cidofovir can be a promising and innovative alternative therapeutic system for the treatment of genital herpes simplex virus and human papilloma virus induced infections in women.

    The aim of the present study was to evaluate chitosan as a vaginal mucoadhesive gel base for econazole nitrate and miconazole nitrate. To this aim, different types of chitosan with different molecular masses and viscosity properties [low molecular mass chitosan (viscosity: 20,000 mPa s), medium molecular mass chitosan (viscosity: 200,000 mPa s), high molecular mass chitosan (viscosity: 800,000 mPa s)] have been used. First, rheological studies were conducted on chitosan gels. Mechanical, syringeability and mucoadhesive properties of chitosan gels were determined. Release profiles of econazole nitrate and miconazole nitrate from chitosan gels were obtained and evaluated kinetically. In addition, anticandidal activities of formulations were determined. Finally, vaginal retention of chitosan gels in rats was evaluated by in vivo distribution studies. Based on the results, it can be concluded that gels prepared with medium molecular mass chitosan might be effectively used for different antifungal agents in the treatment of vaginal candidiosis, since it has high mucoadhesiveness, suitable mechanical and release properties with good vaginal retention.

    Background: Intrauterine insemination (IUI) is one of the most appropriate and cost-effective methods in infertility treatment. Objective: We aimed to investigate effect of vaginal misoprostol on pregnancy rate after IUI. Materials and Methods: Two hundred and ten infertile women who were referred to Infertility Clinic of Alzahra Hospital by an indication of IUI during 2012-2013 were randomly assigned to receive 200 g vaginal misoprostol (n=105) or vaginal placebo (n=105) after IUI. For detecting pregnancy, past 2 weeks, beta human chorionic gonadotropin evaluation was made and if positive, transvaginal sonography was done for evaluation of pregnancy 2-3 weeks later and clinical pregnancy was recorded. Results: Pregnancy had been noted in 24 patients in misoprotol (22.9%) and 27 patients in placebo (25.7%) groups that this difference was not significant (p=0.748). In misoprostol group, 3 case of nausea and vomiting (2.9%) had been observed. Conclusion: According to the results, administering 200 g vaginal misoprostol after IUI doesnt have significant effect on the success rate of IUI. PMID:25653670

    Nanosilver particles are used in various clinical settings because of their antibacterial properties. However, their safety evaluation when used for gynaecological disorders has not been established. Nanosilver particles were administrated in the vagina of New Zealand rabbits, and the pathological appearance of the surrounding tissue was examined by hematoxylin-eosin staining and transmission electron microscopy (TEM) after 1 and 3 days of treatment. The nanosilver content was assessed by plasma mass spectrometry, and the presence of particles in the hepatic portal vein blood was assessed by TEM. The results of our study show that the vaginal administration of nanosilver particles caused ultrastructural changes to the vaginal mucosa, urethra and rectum, with accumulation of particles in all tissues. These results demonstrate a new migration route of nanosilver particles following vaginal administration. They also demonstrate, for the first time, that the vaginal administration of nanosilver particles can enter the blood circulation system by examining the hepatic portal vein blood under the TEM which is the most direct visualized evidence.

    Persistent infection with oncogenic Human Papillomavirus (HPV) is necessary for cervical carcinogenesis. Although evidence suggests that the vaginal microbiome plays a functional role in the persistence or regression of HPV infections, this has yet to be described in women with cervical intra-epithelial neoplasia (CIN). We hypothesised that increasing microbiome diversity is associated with increasing CIN severity. llumina MiSeq sequencing of 16S rRNA gene amplicons was used to characterise the vaginal microbiota of women with low-grade squamous intra-epithelial lesions (LSIL; n?=?52), high-grade (HSIL; n?=?92), invasive cervical cancer (ICC; n?=?5) and healthy controls (n?=?20). Hierarchical clustering analysis revealed an increased prevalence of microbiomes characterised by high-diversity and low levels of Lactobacillus spp. (community state type-CST IV) with increasing disease severity, irrespective of HPV status (Normal?=?2/20,10%; LSIL?=?11/52,21%; HSIL?=?25/92,27%; ICC?=?2/5,40%). Increasing disease severity was associated with decreasing relative abundance of Lactobacillus spp. The vaginal microbiome in HSIL was characterised by higher levels of Sneathia sanguinegens (P?vaginal microbiota diversity and may be involved in regulating viral persistence and disease progression.

    CASE DESCRIPTION A 7-year-old 42-kg (92.4-lb) sexually intact nulliparous female Italian Mastiff was examined because of a history of vaginal prolapse during diestrus. CLINICAL FINDINGS A physical examination revealed vaginal fold prolapse. Abdominal ultrasonography revealed an enlarged uterus with hypoechogenic content, corpora lutea in the ovaries, and a cyst in the right ovary. Hematologic abnormalities included leukocytosis, neutrophilia, mild anemia, and low Hct. Progesterone and estradiol concentrations were 9.36 ng/mL and 30.42 pg/mL, respectively, in serum and 72.72 ng/mL and 792 pg/mL, respectively, in the ovarian cystic fluid. TREATMENT AND OUTCOME Ovariohysterectomy was performed; the prolapsed tissue was repositioned by external manipulation and maintained in situ by temporary apposition of the vulvar lips with a retention suture. Anatomic and histologic examinations of the excised tissues revealed pyometra and papillary cystadenocarcinoma in the right ovary. The vaginal hyperplasia completely regressed at 35 days after surgery; 5 months after surgery, the dog's general condition was considered good. CLINICAL RELEVANCE Findings in this case were indicative of a hormonally active ovarian papillary cystadenocarcinoma in a female dog in diestrus. Hormone production by the cystadenocarcinoma was the predisposing factor that induced pyometra, mucosal hyperplasia, and vaginal fold prolapse in the dog. On the basis of these concurrent disorders, ovariohysterectomy was an appropriate treatment. (J Am Vet Med Assoc 2016;248:822-826). PMID:27003024

    Purpose: We report demographic, clinical, and psychosocial factors associated with adherence to vaginal dilation and describe the sexual and marital or nonmarital dyadic functioning of women following high dose rate (HDR) brachytherapy for endometrial cancer. Methods and Materials: We retrospectively evaluated women aged 18 years or older in whom early-stage endometrial (IAgr3-IIB) cancers were treated by HDR intravaginal brachytherapy within the past 3.5 years. Women with or without a sexual partner were eligible. Patients completed questionnaires by mail or by telephone assessing demographic and clinical variables, adherence to vaginal dilation, dyadic satisfaction, sexual functioning, and health beliefs. Results: Seventy-eight of 89 (88%) eligible women with early-stage endometrial cancer treated with HDR brachytherapy completed questionnaires. Only 33% of patients were adherers, based on reporting having used a dilator more than two times per week in the first month following radiation. Nonadherers who reported a perceived change in vaginal dimension following radiation reported that their vaginas were subjectively smaller after brachytherapy (p = 0.013). Adherers reported more worry about their sex lives or lack thereof than nonadherers (p = 0.047). Patients reported considerable sexual dysfunction following completion of HDR brachytherapy. Conclusions: Adherence to recommendations for vaginal dilator use following HDR brachytherapy for endometrial cancer is poor. Interventions designed to educate women about dilator use benefit may increase adherence. Although sexual functioning was compromised, it is likely that this existed before having cancer for many women in our study.

    Microporous poly(ε-caprolactone) matrices were loaded with an antibacterial agent, ciprofloxacin and an antifungal agent, miconazole nitrate, respectively, for investigations of their potential as controlled vaginal delivery devices. Ciprofloxacin loadings up to 15% w/w could be obtained by increasing the drug content of the poly(ε-caprolactone) solution, while the actual loadings of miconazole were much lower (1-3% w/w) due to drug partition into methanol during the solvent extraction. The kinetics of ciprofloxacin release in simulated vaginal fluid at 37 were characterised by a small burst release phase in the first 24 h, low drug release up to 7 days (10%) and gradual release of up to 80% of the drug content by day 30. Meanwhile, the release kinetics of miconazole-loaded matrices could be effectively described by the Higuchi model with 100% drug release from the highest loaded matrices (3.2% w/w) in 13 days. Ciprofloxacin or miconazole released over 30 and 13 days, respectively, from poly(ε-caprolactone) matrices into simulated vaginal fluid retained high levels of antimicrobial activity in excess of 80% of the activity of the free drug. This study confirms the potential of poly(ε-caprolactone) matrices for delivering antimicrobial agents in the form of an intra-vaginal device. PMID:22684517

    Vaginitis is one of the commonest reproductive tract infections in sexually active women. In the present study clinicoetiological characterization of infectious vaginitis amongst 380 women of reproductive age group (1845 years) was done. Bacterial vaginosis (BV) was detected by Nugent's scoring, Candida infection by culture, and trichomoniasis (TV) by wet mount. One hundred and ten (28.9%) women presented with symptoms of vaginitis. The presenting symptoms were vaginal discharge 106 (96.4%), vulval itching/irritation 19 (17.3%), malodor 5 (4.5%), pain in abdomen 3 (2.7%), and dysuria 1 (0.9%). The commonest etiology detected was Candida in 33 (30%) cases, of which 18 (54.5%) were C. albicans and 15 (45.5%) non-albicans Candida (NAC) infections. The NAC isolates were C. glabrata (n = 10), C. tropicalis (n = 3), and C. krusei (n = 2). BV and TV were observed in 19 (17.3%) and 2 (1.8%) cases, respectively. A statistically significant association between Candida infection and presence of curdy-white discharge (p = 0.001) and vulval itching/irritation (p = 0.007) was noted. To conclude, we observed the etiological predominance of Candida infection, with considerable prevalence of NAC, indicating the need for microbiological investigation up to species level in cases of Candida infections, to ensure appropriate management.

    Estrogen and progesterone regulate proliferation and differentiation of epithelial cells in the female genital tract. We investigated the effects of these hormones on reconstructed human organotypic vaginal epithelial tissue models (EpiVaginal). We ascertained that epithelial cells in the tissue models express estrogen and progesterone receptors. Treatment with estradiol-17? (E(2)) significantly increased epithelium thickness and transepithelial electrical resistance (TEER), whereas progesterone (P) treatment resulted in thinning of the epithelium and decreased TEER when compared with untreated controls. Exposure to E(2) increased (1) the expression of the progesterone receptor B (PR-B), (2) accumulation of glycogen in suprabasal cells, (3) epithelial differentiation, and (4) the expression of a number of gene pathways associated with innate immunity, epithelial differentiation, wound healing, and antiviral responses. These findings indicate that EpiVaginal tissues are hormone responsive and can be used to study the role of female reproductive hormones in innate immune responses, microbial infection, and drug delivery in the vaginal mucosa.

    Carbamazepine indicated for the control of epilepsy, undergoes extensive hepatic first-pass metabolism after oral administration. A vaginal dosage form of carbamazepine is not commercially available. Conventional suppository having poor retention in the vaginal tract, as they are removed in a short time by the tract's self-cleansing action, having poor patient compliance. To overcome such problems, delivery system with mucoadhesive polymers polyox WSR N-60K and Ucarflock 302 that prolong drug permanence on the vaginal mucosa were developed. In the present study the suitability of gelucires to formulate vaginal pesseries was investigated. The possible modification of carbamazepine release kinetics by using gelucires blends and hydrophilic additives in the pesseries was evaluated. It was observed that among gelucire grades melting point higher than 37 degrees C, the release rate proved to be highly dependant on HLB value and matrix composition. In most of the formulations carbamazepine release occurred by disintegration and erosion of the matrices which is depending upon the vehicle employed. The aging study revealed that the formulations containing G50/13 and G50/13-G44/14 blends undergo some changes during one year of shelf aging. From the results obtained it can be concluded that different gelucire grades and their blends along with hydrophilic polymer could be successesively used to formulate prolong release carbamazepine pesseries.

    The relevance of diethylstilbestrol (DES) administration to neonatal mice as a model for human pathology attributed to the use of DES in high-risk pregnancies has been investigated, particularly with respect to cervical and vaginal changes in female offspring. Neonatal DES treatment of mice results in tonic pituitary gonadotropin release and continuous estrogen secretion by the ovary. Studies were designed to determine the effect of this altered ovarian endocrine activity on cervical and vaginal histopathology. Ovariectomy of DES-treated mice, with or without estradiol replacement, did not eliminate the lesions, nor did estrogen and progesterone administered in a regimen intended to mimic estrous cycle changes. Induction of the constant estrus state by neonatal estradiol benzoate or testosterone propionate administration or by exposure to constant light did not produce the type of vaginal or cervical changes seen in DES mice. Thus, altered ovarian function is apparently not required for the vaginal and cervical changes appearing in later life. A role for endogenous (or exogenous) ovarian hormones in the developmental progression toward normality is suggested. PMID:3401547

    Introduction Innate activity against Escherichia coli in female genital secretions may represent contributions from vaginal bacteria and host soluble immune mediators. We analyzed the relationship between E. coli inhibitory activity, soluble immune mediators, and vaginal bacteria in participants in MTN-004, a placebo-controlled trial of VivaGel, a candidate product for topical HIV pre-exposure prophylaxis. Methods Escherichia coli inhibitory activity was quantified by colony reduction assay. Endocervical concentrations of interleukin (IL)-1?, IL-6, IL-12p40, macrophage inflammatory protein (MIP)-1?, granulocyte macrophage colony-stimulating factor (GM-CSF), lactoferrin, and secretory leukocyte protease inhibitor (SLPI) were quantified to generate a cumulative mediator score. Vaginal bacteria were characterized by quantitative cultures. Results In the two placebo arms, higher soluble immune mediator score was associated with greater E. coli inhibitory activity (? = 17.49, 95% CI [12.77, 22.21] and ? = 13.28, 95% CI [4.76, 21.80]). However, in the VivaGel arm, higher concentrations of E. coli (? = ?3.80, 95% CI [?6.36, ?1.25]) and group B Streptococcus (? = ?3.91, 95% CI [?6.21, ?1.60]) were associated with reduced E. coli inhibitory activity. Conclusions Both host mediators and vaginal bacteria impact E. coli inhibition in genital secretions. The relative contributions of host mediators and bacteria varied between women who used VivaGel vs placebos. PMID:26118476

    Vaginal infections are one of the most gynecological frequently diseases observed and with significant psychological and clinical implications. Their pharmacological treatment may require different options, but even today, scientific literature and international guidelines recommend the use of metronidazole for the treatment of bacterial vaginosis (BV) and trichomoniasis, and the clotrimazole for fungal infections from Candida (VVC). In this contest, the topical association of clotrimazole-metronidazole (vaginal pessaries, cream and douches) represents a current reference treatment for these types of infections with a number of important pharmacological properties. This combination allows an effective activity against to a broad spectrum of pathogens (bacterial, fungal and protozoan), a feature particularly relevant in the case of mixed infections. Furthermore it allows a synergistic action that improve the therapeutic abilities of the individual components, a reduction of the spontaneous resistance of some microorganisms and the activity against symptoms and signs of vaginal inflammation with maintaining the vaginal ecosystem, since they have no activity against endogenous lactobacilli. Finally, recent studies have shown the ability of the topical association of metronidazole-clotrimazole to inhibit the in vitro phenotypic switching of Candida albicans, and its effectiveness against Recurrent Vulvovaginal Candidiasis (RVVC).

    We previously reported non-aqueous silicone elastomer gels (SEGs) for sustained vaginal administration of the CCR5-targeted entry inhibitor maraviroc. Here, we describe chemically modified SEGs (h-SEGs) in which the hydrophobic cyclomethicone component was partially replaced with relatively hydrophilic silanol-terminated polydimethylsiloxanes (st-PDMS). Maraviroc and emtricitabine (a nucleoside reverse transcriptase inhibitor), both currently under evaluation as topical microbicides to counter sexual transmission of human immunodeficiency virus type 1 (HIV-1), were used as model antiretroviral (ARV) drugs. Gel viscosity and in vitro ARV release were significantly influenced by st-PDMS molecular weight and concentration in the h-SEGs. Unexpectedly, gels prepared with lower molecular weight grades of st-PDMS showed higher viscosities. h-SEGs provided enhanced release over 24 h compared with aqueous hydroxyethylcellulose (HEC) gels, did not modify the pH of simulated vaginal fluid (SVF), and were shown to less cytotoxic than standard hydroxyethylcellulose (HEC) vaginal gel. ARV solubility increased as st-PDMS molecular weight decreased (i.e. as percentage hydroxyl content increased), helping to explain the in vitro release trends. Dye ingression and SVF dilution studies confirmed the increased hydrophilicity of the h-SEGs. h-SEGs have potential for use in vaginal drug delivery, particularly for ARV-based HIV-1 microbicides.

    Inexpensive and female-controlled pre-exposure prophylaxis strategies to prevent mucosal transmission of the virus, is urgently needed with the rising prevalence of human immunodeficiency virus (HIV-1 and HIV2) infections in women. Zidovudine-loaded bioadhesive vaginal gel may become one of the very useful strategies, as it can be used not only for controlled release but also for enhancing bioavailability. Drug delivery through vaginal gel is a promising area for continued research with the aim of achieving controlled release with enhanced bioavailability over longer periods of time. The aim of the study was to develop a newer prolong releasing Zidovudine (AZT) bioadhesive vaginal gel to treat HIV infections with increased patient convenience. AZT-loaded bioadhesive vaginal gel was prepared successfully by using cold mechanical method. F3 formulation containing carbopolHPMC (1:3) was selected and evaluated in order to achieve objectives of this study. In vitro drug release study of F3 showed in 24 h drug released following case I Fickian (n ? 0.5) transport mechanism, and in vivo drug release was found much better (Tmax), (Cmax), and bioavailability (F) comparison with oral pour drug solution. It was also showed good extrudability, spreadability, and bioadhesive strength. A generalized protocol, for the further research, in this area will surely expected to yield significant outcome with improved drug delivery system. PMID:21731351

    We have developed fast-disintegrating tablets comprising starch-based pellets and excipient granules for intravaginal drug delivery. The purpose of this study was to evaluate the intravaginal disintegration, distribution and retention behavior of these tablets in sheep and women using colposcopy as visualization technique. One tablet was administered to each study subject (n = 6) and repeated colposcopy examination was performed over a 48?h and 24?h period in sheep and women, respectively. Colposcopy in sheep indicated that in vivo tablet disintegration was initiated within 30?min of vaginal administration and that due to disintegration of the pellets themselves, the formulation was transformed into a gel-like mass which distributed throughout the entire vaginal cavity within 2-4?h. In vivo tablet disintegration after intravaginal administration to women was complete within 4?h, whereby the formulation gradually spread throughout the vaginal cavity as complete covering was observed after 12 and 24?h. The persistent retention (up to 24 and 48?h in women and sheep, respectively) confirmed the long retention time of this vaginal formulation. PMID:23009084

    Objective To compare the clinical efficacy of two different dosing regimens of vaginal misoprostol for labour induction. Material and Methods This is an open label randomised controlled trial of 100 eligible women with obstetrical or medical indications for labour induction at a secondary level care hospital on the west coast of India. Women were randomised to receive either a single 50 ?g dose or multiple 25 ?g doses (maximum of three doses) of misoprostol in the posterior vaginal fornix. The main outcome measure was induction to vaginal delivery interval. Results Mean induction delivery interval was 18.5813.73 and 14.4213.2 hours (P=0.73) in the 50 ?g and 25 ?g misoprostol group respectively. Delivery rate within 24 hours were 60% (30/50), in 50 ?g group and 68% (34/50) in 25 ?g group (P=0.53). The rates of caesarean section and operative vaginal delivery were similar in both groups. There was no significant difference in maternal side effects and neonatal outcome among regimens. Conclusion There was no statistically significant difference between the two regimens in terms of clinical efficacy. PMID:24591876

    The aim of the present study was to compare clinical and radiological findings when assessing posterior vaginal wall prolapse. Defecography can be used to complement the clinical evaluation in patients with posterior vaginal wall prolapse. Further development of the defecography technique, using contrast medium in the urinary bladder and intraperitoneally, have resulted in cystodefecoperitoneography (CDP). Thirty-eight women underwent clinical examination using the pelvic organ prolapse quantification system (POP-Q) followed by CDP. All patients answered a standardized bowel function questionnaire. Statistical analysis measuring correlation between POP-Q and CDP using Pearson's correlation coefficient (r) and Spearman's rank order correlation coefficient (rs) demonstrated a poor to moderate correlation, r=0.49 and rs=0.55. Although there was a strong association between large rectoceles (>3 cm) at CDP and symptoms of rectal emptying difficulties (p<0.001), severity and prevalence of bowel dysfunction showed poor coherence with clinical prolapse staging and findings at radiological imaging. Vaginal topography and POP-Q staging predict neither radiological size nor visceral involvement in posterior vaginal wall prolapse. Radiological evaluation may therefore be a useful complement in selected patients. PMID:15372142

    The interaction and mixing between a bilayer sample of mucus and vaginal formulation was evaluated through viscosity measurements with respect to time and shear. Physical mixtures of mucus and vaginal formulation were used as controls. Three test protocols were designed: (1) constant shear, (2) intermittent shear, and (3) delayed shear. Several marketed vaginal products (Gynol II, KY Plus, KY, and Advantage-S) and experimental formulations (C31G with hydroxyethylcellulose [HEC]) were evaluated and compared by these tests. The results of the constant shear test showed that the shear stress profile of the bilayer approached that of the corresponding physical mixture, consistent with complete mixing of the bilayer under shear. The time taken for the bilayer to mix completely was in the following order: KY Plus > Gynol II and C31G > KY > Advantage-S. Under the intermittent shear protocol, the following order for complete mixing was observed: KY Plus > C31G > Gynol II > KY > Advantage-S. The 2 products evaluated by the delayed shear test, C31G and Gynol II, were both completely mixed at 180 minutes. The development of an in vitro test, when coupled with in vivo data, should serve in the screening and evaluation of future vaginal formulations. PMID:15198538
