    The properties of meshes used in reconstructive surgery affect the host response and biomechanical characteristics of the grafted tissue. Whereas durable synthetics induce a chronic inflammation, biological grafts are usually considered as more biocompatible. The location of implantation is another determinant of the host response: the vagina is a different environment with specific function and anatomy. Herein, we evaluated a cross-linked acellular collagen matrix (ACM), pretreated by the anti-calcification procedure ADAPT® in a sheep model for vaginal surgery. Ten sheep were implanted with a cross-linked ACM, and six controls were implanted with a polypropylene (PP; 56 g/m 2 ) control. One implant was inserted in the lower rectovaginal septum, and one was used for abdominal wall defect reconstruction. Grafts were removed after 180 days; all graft-related complications were recorded, and explants underwent bi-axial tensiometry and contractility testing. Half of ACM-implanted animals had palpable induration in the vaginal implantation area, two of these also on the abdominal implant. One animal had a vaginal exposure. Vaginal ACMs were 63 % less stiff compared to abdominal ACM explants ( p  = 0.01) but comparable to vaginal PP explants. Seven anterior vaginal ACM explants showed areas of graft degradation on histology. There was no overall difference in vaginal contractility. Considering histologic degradation in the anterior vaginal implant as representative for the host, posterior ACM explants of animals with degradation had a 60 % reduced contractility as compared to PP ( p  = 0.048). Three abdominal implants showed histologic degradation; those were more compliant than non-degraded implants. Vaginal implantation with ACM was associated with graft-related complications (GRCs) and biomechanical properties comparable to PP. Partially degraded ACM had a decreased vaginal contractility.

    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.

    Treatment of gynecological cancer commonly involves pelvic radiation therapy (RT) and/or brachytherapy. A commonly observed side effect of such treatment is radiation-induced vaginal stenosis (VS). This review analyzed the incidence, pathogenesis, clinical manifestation(s) and assessment and grading of radiation-induced VS. In addition, risk factors, prevention and treatment options and follow-up schedules are also discussed. The limited available literature on many of these aspects suggests that additional studies are required to more precisely determine the best management strategy of this prevalent group after RT.

    Primary carcinoma of the vagina is rare, constituting only 1 to 2% of all neoplasms arising in the female genital tract. From 1950-1974, 36 patients with carcinoma of the vagina were treated with radiation at Memorial Sloan-Kettering Cancer Center (MSKCC); 35 (96%) had epidermoid carcinoma and one patient (4%) had adenocarcinoma. These patients were staged according to FIGO. Fourteen patients (39%) were Stage I; six patients (17%) were Stage II; three patients (8%) were Stage III; and 13 patients (36%) were Stage IV. Nine patients (25%) were treated with external radiation and interstitial implant; seven patients (20%) were treated withmore » interstitial implant alone; nine patients (25%) were treated with external radiation alone and 11 patients (30%) with external radiation and intracavitary radiation. The five year NED survival was 71% in Stage I, 66% in Stage II, 33% in Stage III and 0% in Stage IV. This paper discusses radiotherapy management of primary carcinoma of the vagina.« less

    Many diseases necessitate the substitution of vaginal tissues. Current replacement therapies are associated with many complications. In this study, we aimed to create bioengineered neovaginas with the self-assembly technique using autologous vaginal epithelial (VE) and vaginal stromal (VS) cells without the use of exogenous materials and to document the survival and incorporation of these grafts into the tissues of nude female mice. Epithelial and stromal cells were isolated from vaginal biopsies. Stromal cells were driven to form collagen sheets, 3 of which were superimposed to form vaginal stromas. VE cells were seeded on top of these stromas and allowed to mature in an air-liquid interface. The vaginal equivalents were implanted subcutaneously in female nude mice, which were sacrificed after 1 and 2 weeks after surgery. The in vitro and animal-retrieved equivalents were assessed using histologic, functional, and mechanical evaluations. Vaginal equivalents could be handled easily. VE cells formed a well-differentiated epithelial layer with a continuous basement membrane. The equivalent matrix was composed of collagen I and III and elastin. The epithelium, basement membrane, and stroma were comparable to those of native vaginal tissues. The implanted equivalents formed mature vaginal epithelium and matrix that were integrated into the mice tissues. Using the self-assembly technique, in vitro vaginal tissues were created with many functional and biological similarities to native vagina without any foreign material. They formed functional vaginal tissues after in vivo animal implantation. It is appropriate for vaginal substitution and disease modeling for infectious studies, vaginal applicants, and drug testing.

    2013-06-01

    To report two year clinical outcomes of image guided radiation therapy (IGRT) to the vaginal cuff and pelvic lymph nodes in a series of high-risk endometrial cancer patients. Twenty-six consecutive high-risk endometrial cancer patients requiring adjuvant radiation to the vaginal cuff and regional lymph nodes were treated with vaginal cuff fiducial-based IGRT. Seventeen (65%) received sequential chemotherapy, most commonly with a sandwich technique. Brachytherapy followed external radiation in 11 patients to a median dose of 18 Gy in 3 fractions. The median external beam dose delivered was 47.5 Gy in 25 fractions. All 656 fractions were successfully imaged and treated. The median overall translational shift required for correction was 9.1 mm (standard deviation, 5.2 mm) relative to clinical set-up with skin tattoos. Shifts of 1 cm, 1.5 cm, and 2 cm or greater were performed in 43%, 14%, and 4% of patients, respectively. Acute grade 2 gastrointestinal (GI) toxicity occurred in eight patients (30%) and grade 3 toxicity occurred in one. At two years, there have been no local or regional failures and actuarial overall survival is 95%. Daily image guidance for high-risk endometrial cancer results in a low incidence of acute GI/genitourinary (GU) toxicity with uncompromised tumor control at two years. Vaginal cuff translations can be substantial and may possibly result in underdosing if not properly considered.

    To evaluate variations in bladder and rectal volume and the position of the vaginal vault during a 5-week course of pelvic intensity-modulated radiation therapy (IMRT) after hysterectomy. Twenty-four patients were instructed how to fill their bladders before simulation and treatment. These patients underwent computed tomography simulations with full and empty bladders and then underwent rescanning twice weekly during IMRT; patients were asked to have full bladder for treatment. Bladder and rectal volumes and the positions of vaginal fiducial markers were determined, and changes in volume and position were calculated. The mean full and empty bladder volumes at simulation were 480 cc (range, 122-1,052) and 155 cc (range, 49-371), respectively. Bladder volumes varied widely during IMRT: the median difference between the maximum and minimum volumes was 247 cc (range, 96-585). Variations in rectal volume during IMRT were less pronounced. For the 16 patients with vaginal fiducial markers in place throughout IMRT, the median maximum movement of the markers during IMRT was 0.59 cm in the right-left direction (range, 0-0.9), 1.46 cm in the anterior-posterior direction (range, 0.8-2.79), and 1.2 cm in the superior-inferior direction (range, 0.6-2.1). Large variations in rectal or bladder volume frequently correlated with significant displacement of the vaginal apex. Although treatment with a full bladder is usually preferred because of greater sparing of small bowel, our data demonstrate that even with detailed instruction, patients are unable to maintain consistent bladder filling. Variations in organ position during IMRT can result in marked changes in the position of the target volume and the volume of small bowel exposed to high doses of radiation.

    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

    Autonomous wireless body-implanted devices for biotelemetry, telemedicine, and neural interfacing constitute an emerging technology providing powerful capabilities for medicine and clinical research. We study the through-tissue electromagnetic propagation mechanisms, derive the optimal frequency range, and obtain the maximum achievable efficiency for radiative energy transfer from inside a body to free space. We analyze how polarization affects the efficiency by exciting TM and TE modes using a magnetic dipole and a magnetic current source, respectively. Four problem formulations are considered with increasing complexity and realism of anatomy. The results indicate that the optimal operating frequency f for deep implantation (with a depth d ≳3 cm ) lies in the (108- 109 )-Hz range and can be approximated as f =2.2 ×107/d . For a subcutaneous case (d ≲3 cm ), the surface-wave-induced interference is significant: within the range of peak radiation efficiency (about 2 ×108 to 3 ×109 Hz ), the max-to-min ratio can reach a value of 6.5. For the studied frequency range, 80%-99% of radiation efficiency is lost due to the tissue-air wave-impedance mismatch. Parallel polarization reduces the losses by a few percent; this effect is inversely proportional to the frequency and depth. Considering the implantation depth, the operating frequency, the polarization, and the directivity, we show that about an order-of-magnitude efficiency improvement is achievable compared to existing devices.

    The purpose of this study was to examine the dose enhancement at bone-implant interfaces from scattered radiation during simulated head and neck radiotherapy. Three cylindric implant systems with different compositions (pure titanium, titanium-aluminum-vanadium alloy, titanium coated with hydroxyapatite) and a high gold content transmandibular implant system (gold-copper-silver alloy) were studied. Extruded lithium fluoride single crystal chips were used as thermoluminescent material to measure radiation dose enhancement at 0, 1, and 2 mm from the bone-implant interface. The relative doses in buccal, lingual, mesial, and distal directions were also recorded and compared. The results indicated that the highest dose enhancement occurred at a distance of 0 mm from the bone-implant interface for all the implant systems studied. The transmandibular implants had higher scattered radiation than other groups at 0 mm and at 1 mm from the bone-implant interface. There was no significant difference of dose enhancement between buccal, lingual, mesial, and distal directions. Titanium implants coated with hydroxyapatite demonstrated the best results under the simulated irradiation.

    The purpose of this study was to analyze the long-term success and factors potentially influencing the success of dental implants placed in patients with head and neck cancer who underwent radiation therapy with a minimum total dose of 50Gy during the years 1995-2010. Thirty-five patients (169 dental implants) were included in this study. Data on demographic characteristics, tumour type, radiation therapy, implant sites, implant dimensions, and hyperbaric oxygen therapy (HBOT) were obtained from the medical records and analyzed. Implant survival was estimated using Kaplan-Meier survival curves. Seventy-nine dental implants were placed in the maxilla and 90 in the mandible. The mean follow-up after implant installation was 7.4 years (range 0.3-14.7 years). The overall 5-year survival rate for all implants was 92.9%. Sex (P<0.001) and the mode of radiation therapy delivery (P=0.005) had a statistically significant influence on implant survival. Age, time of implantation after irradiation, implant brand and dimensions, and HBOT had no statistically significant influence on implant survival. Osseointegrated dental implants can be used successfully in the oral rehabilitation of patients with head and neck cancer with a history of radiation therapy. Risk factors such as sex and the mode of radiation therapy delivery can affect implant survival. Copyright © 2018 International Association of Oral and Maxillofacial Surgeons.

    2005-06-30

    We have implanted GaN with Mg ions over an energy range of 200keV to 1MeV at substrate temperatures of -150 (cold) and +300 deg. C (hot). The radiation damage formation in GaN was increased for cold implants when compared to samples implanted at elevated temperatures. The increase in damage formation is due to a reduction in the dynamic defect annealing during ion irradiation. The dopant stopping in the solid also depends upon the implant temperature. For a fixed implant energy and dose, Mg ions have a shorter range in GaN for cold implants when compared to hot implants which ismore » caused by the increase in scattering centres (disorder)« less

    To investigate the dose-response relation between the dose to the vagina and the patient-reported symptom 'absence of vaginal elasticity' and how time to follow-up influences this relation. The study included 78 long-term gynecological cancer survivors treated between 1991 and 2003 with external beam radiation therapy. Of those, 24 experienced absence of vaginal elasticity. A normal tissue complication model is introduced that takes into account the influence of time to follow-up on the dose-response relation and the patient's age. The best estimates of the dose-response parameters were calculated using Probit, Probit-Relative Seriality (RS) and Probit-time models. Log likelihood (LL) values and the Akaike Information Criterion (AIC) were used to evaluate the model fit. The dose-response parameters for 'absence of vaginal elasticity' according to the Probit and Probit-time models with the 68% Confidence Intervals (CI) were: LL=-39.8, D 50 =49.7 (47.2-52.4) Gy, γ 50 =1.40 (1.12-1.70) and LL=-37.4, D 50 =46.9 (43.5-50.9) Gy, γ 50 =1.81 (1.17-2.51) respectively. The proposed model, which describes the influence of time to follow-up on the dose-response relation, fits our data best. Our data indicate that the steepness of the dose-response curve of the dose to the vagina and the symptom 'absence of vaginal elasticity' increases with time to follow-up, while D 50 decreases.

    As an alternative to polypropylene mesh, we explored an extracellular matrix (ECM) bioscaffold derived from urinary bladder matrix (MatriStem™) in the repair of vaginal prolapse. We aimed to restore disrupted vaginal support simulating application via transvaginal and transabdominal approaches in a macaque model focusing on the impact on vaginal structure, function, and the host immune response. In 16 macaques, after laparotomy, the uterosacral ligaments and paravaginal attachments to pelvic side wall were completely transected (IACUC# 13081928). 6-ply MatriStem was cut into posterior and anterior templates with a portion covering the vagina and arms simulating uterosacral ligaments and paravaginal attachments, respectively. After surgically exposing the correct anatomical sites, in 8 animals, a vaginal incision was made on the anterior and posterior vagina and the respective scaffolds were passed into the vagina via these incisions (transvaginal insertion) prior to placement. The remaining 8 animals underwent the same surgery without vaginal incisions (transabdominal insertion). Three months post implantation, firm tissue bands extending from vagina to pelvic side wall appeared in both MatriStem groups. Experimental endpoints examining impact of MatriStem on the vagina demonstrated that vaginal biochemical and biomechanical parameters, smooth muscle thickness and contractility, and immune responses were similar in the MatriStem no incision group and sham-operated controls. In the MatriStem incision group, a 41% decrease in vaginal stiffness (P=0.042), a 22% decrease in collagen content (P=0.008) and a 25% increase in collagen subtypes III/I was observed vs. Sham. Active MMP2 was increased in both Matristem groups vs. Sham (both P=0.002). This study presents a novel application of ECM bioscaffolds as a first step towards the rebuilding of vaginal support. Pelvic organ prolapse is a common condition related to failure of the supportive soft tissues of the vagina

    Abnormal vaginal bleeding in a postmenarchal adolescent patient is most often related to dysfunctional uterine bleeding. However, there are other potential etiologies, including hematologic disorders, infections, and oncologic problems. We present a 12-year-old girl who presented with prolonged vaginal bleeding and was ultimately diagnosed with rhabdomyosarcoma. In this article, we discuss the approach to a patient with vaginal bleeding along with a more in-depth review of risk stratification in rhabdomyosarcoma, including treatment options such as chemotherapy, surgery, and radiation therapy.

  20. Odour recognition by male hamsters: discrimination of the hormonal state of females by odour from vaginal secretions.

    PubMed

    Steel, E

    1985-05-01

    Male hamsters were tested for their interest in females on different days of the oestrous cycle. Behaviour of males toward novel females was measured and (after exposure to vaginal secretion) towards females that matched or did not match that vaginal odour. Because pro-oestrous (day 4) females lay trails of vaginal secretion and will become receptive within a few hours, it was predicted that males would show more interest in day 4 than in other dioestrous females. While males showed no preference for novel, pro-oestrous females over dioestrous females, after pre-exposure to odour, their response to females was determined by the cycle day of the vaginal secretion to which they had been exposed. Males pre-exposed to vaginal odour from females carrying large implants of oestrogen preferred to spend more time with females who matched that vaginal odour than mismatching females and to sniff them more. This preference was not seen if the females carried small oestrogen implants or had no replacement oestrogen. This suggests that pro-oestrous females (who are known to have high circulating levels of oestrogen) can, by means of their scent-marking behaviour, attract and keep males nearby until they become receptive.

    2011-01-01

    Many congenital and acquired diseases result in the absence of a normal vagina. Patients with these conditions often require reconstructive surgery to achieve satisfactory cosmesis and physiological function, and a variety of materials have been used as tissue sources. Currently employed graft materials such as collagen scaffolds and small intestine are not ideal in that they fail to mimic the physiology of normal vaginal tissue. Engineering of true vaginal tissue from a small biopsy of autologous vagina should produce a superior graft material for vaginal reconstruction. This review describes our current experience with the engineering of such tissue and its use for vaginal reconstruction in animal models. Our successful construction and implantation of neovaginas through tissue engineering techniques demonstrates the feasibility of similar endeavors in human patients. Additionally, the use of pluripotent stem cells instead of autologous tissue could provide an "off-the-shelf" tissue source for vaginal reconstruction.

  3. Bilateral implant reconstruction does not affect the quality of postmastectomy radiation therapy

    To determine if the presence of bilateral implants, in addition to other anatomic and treatment-related variables, affects coverage of the target volume and dose to the heart and lung in patients receiving postmastectomy radiation therapy (PMRT). A total of 197 consecutive women with breast cancer underwent mastectomy and immediate tissue expander (TE) placement, with or without exchange for a permanent implant (PI) before radiation therapy at our center. PMRT was delivered with 2 tangential beams + supraclavicular lymph node field (50 Gy). Patients were grouped by implant number: 51% unilateral (100) and 49% bilateral (97). The planning target volume (PTV)more » (defined as implant + chest wall + nodes), heart, and ipsilateral lung were contoured and the following parameters were abstracted from dose-volume histogram (DVH) data: PTV D{sub 95%} > 98%, Lung V{sub 20}Gy > 30%, and Heart V{sub 25}Gy > 5%. Univariate (UVA) and multivariate analyses (MVA) were performed to determine the association of variables with these parameters. The 2 groups were well balanced for implant type and volume, internal mammary node (IMN) treatment, and laterality. In the entire cohort, 90% had PTV D{sub 95%} > 98%, indicating excellent coverage of the chest wall. Of the patients, 27% had high lung doses (V{sub 20}Gy > 30%) and 16% had high heart doses (V{sub 25}Gy > 5%). No significant factors were associated with suboptimal PTV coverage. On MVA, IMN treatment was found to be highly associated with high lung and heart doses (both p < 0.0001), but implant number was not (p = 0.54). In patients with bilateral implants, IMN treatment was the only predictor of dose to the contralateral implant (p = 0.001). In conclusion, bilateral implants do not compromise coverage of the target volume or increase lung and heart dose in patients receiving PMRT. The most important predictor of high lung and heart doses in patients with implant-based reconstruction, whether unilateral or bilateral, is

    BACKGROUND In IVF, Luteal phase support is usually performed using vaginal progesterone. A part of patients using this route reports being uncomfortable with this route. We tried to study whether the rectal route could be an effective alternative and associated with less discomfort. PATIENTS AND METHODS A prospective randomized controlled study. All patient were eligible for IVF treatment for infertility. After oocyte pickup, 186 patients were allocated to one the following protocols for luteal phase support: (i) rectal pessaries group: natural progesterone pessaries administered rectally 200 mg three times a day, (ii) vaginal pessaries group: natural progesterone pessaries administered vaginally 200 mg three times a day), and (iii) vaginal capsules group: natural micronized progesterone capsules administered vaginally 200 mg three times a day. On the day of pregnancy test, patients were asked to fill in a questionnaire conducted by an investigator in order to assess the tolerability and side effects of the LPS treatment taken. The primary endpoint was the occurrence of perineal irritation. RESULTS Fifty eight patients were assigned to the rectal pessaries group, 68 patients to the vaginal pessaries group, and 60 patients to the vaginal capsules group. All patients adhered to their allocated treatment. Implantation and clinical pregnancy rates per transfer did not differ between the three groups. Perineal irritation, which was our primary endpoint, was the same for all the three groups (respectively 1.7 % versus 5.9 % versus 11.7%). Regarding the other side effects, more patients experienced constipation and flatulence with the rectal route, whereas more patients reported vaginal discharge in the vaginal capsules group. CONCLUSION Rectal administration for luteal phase support is effective and well accepted alternative to vaginal route. PMID:28096703

    The primary objective of this study was to evaluate the correlation among symptoms, signs, and the number of lactobacilli in postmenopausal vaginal atrophy. The secondary objective was to develop a new parameter to improve the correlation. A cross-sectional descriptive study. Naturally postmenopausal women aged 45-70 years with at least one clinical symptom of vaginal atrophy of moderate to severe intensity were included in this study. All of the objective parameters (vaginal atrophy score, vaginal pH, the number of lactobacilli, vaginal maturation index, and vaginal maturation value) were evaluated and correlated with vaginal atrophy symptoms. A new parameter of vaginal atrophy, vaginal atrophy symptoms II, was developed and consists of the two most bothersome symptoms (vaginal dryness and dyspareunia). Vaginal atrophy symptoms II was analyzed for correlation with the objective parameters. A total of 132 naturally postmenopausal women were recruited for analysis. Vaginal pH was the only objective parameter found to have a weak correlation with vaginal atrophy symptoms (r = 0.273, p = 0.002). The newly developed vaginal atrophy symptoms II parameter showed moderate correlation with vaginal pH (r = 0.356, p < 0.001) and a weak correlation with the vaginal atrophy score (r = 0.230, p < 0.001). History of sexual intercourse within 3 months was associated with a better correlation between vaginal atrophy symptoms and the objective parameters. Vaginal pH was significantly correlated with vaginal atrophy symptoms. The newly developed vaginal atrophy symptoms II was associated with a better correlation. The vaginal atrophy symptoms II and vaginal pH may be better tools for clinical evaluation and future study of the vaginal ecosystem.

    The aim of this study was to develop an appropriate definition for vaginal cuff and paracolpium clinical target volume (CTV) for postoperative intensity modulated radiation therapy in patients with uterine cervical cancer. A working subgroup was organized within the Radiation Therapy Study Group of the Japan Clinical Oncology Group to develop a definition for the postoperative vaginal cuff and paracolpium CTV in December 2013. The group consisted of 5 radiation oncologists who specialized in gynecologic oncology and a gynecologic oncologist. A comprehensive literature review that included anatomy, surgery, and imaging fields was performed and was followed by multiple discreet face-to-face discussions and e-mail messages before a final consensus was reached. Definitions for the landmark structures in all directions that demarcate the vaginal cuff and paracolpium CTV were decided by consensus agreement of the working group. A table was created that showed boundary structures of the vaginal cuff and paracolpium CTV in each direction. A definition of the postoperative cervical cancer vaginal cuff and paracolpium CTV was developed. It is expected that this definition guideline will serve as a template for future radiation therapy clinical trial protocols, especially protocols involving intensity modulated radiation therapy.

  10. Vaginal disorders.

    PubMed

    Soderberg, S F

    Chronic vaginitis is the most common vaginal disorder. Dogs with vaginitis show no signs of systemic illness but often lick at the vulva and have purulent or hemorrhagic vaginal discharges. Vaginitis is most commonly secondary to a noninfectious inciting factor such as congenital vaginal anomalies, clitoral hypertrophy, foreign bodies, trauma to the vaginal mucosa, or vaginal tumors. Inspection of the caudal vagina and vestibule both visually and digitally will often reveal the source of vaginal irritation. Vaginal cytology is used to establish the stage of the estrous cycle as well as distinguish uterine from vaginal sources of discharge. Vaginal cultures are used to establish the predominant offending organism associated with vaginal discharges and may be used as a guide for selection of a therapeutic agent. Vaginitis is best managed by removing the inciting cause and treating the area locally with antiseptic douches. Congenital malformations at the vestibulovaginal or vestibulovulvar junction may prevent normal intromission. Affected bitches may be reluctant to breed naturally because of pain. Such defects are detected best by digital examination. Congenital vaginal defects may be corrected by digital or surgical means. Prolapse of tissue through the lips of the vulva may be caused by clitoral hypertrophy, vaginal hyperplasia, or vaginal tumors. Enlargement of clitoral tissue is the result of endogenous or exogenous sources of androgens. Treatment of this condition includes removal of the androgen source and/or surgical removal of clitoral tissue. Vaginal hyperplasia is detected during proestrus or estrus of young bitches. Hyperplastic tissue will regress during diestrus. Tissue that is excessively traumatized and/or prolapse of the entire vaginal circumference may be removed surgically. Ovariohysterectomy may be used to prevent recurrence. Vaginal tumors are detected most often in older intact bitches. Such tumors are generally of smooth muscle or fibrous

    1985-12-01

    The effects of the spermicide benzalkonium chloride (BKC) were studied on the conceptus of rat. Single doses (0, 25, 50, 100 or 200 mg kg-1) of aqueous solutions of BKC were administered intravaginally (1 ml kg-1) on gestational day 1. The vulval metallic clips, used to prevent leakage of the solution, were removed 24 h post-treatment. Fetuses were obtained and examined for malformations on day 21 of gestation. slight to copious amounts of vaginal discharge and vaginitis were noticed in rats treated with the two largest doses of BKC. A dose-related increase in resorptions and fetal death, reduction in litter size and weight were observed in BKC-treated dams. The conceptus loss seemed to occur both before and after implantation. BKC did not cause any discernible visceral malformations, although minor sternal defects occurred in fetuses exposed to 100 and 200 mg kg-1 of the spermicide. These results suggest that single vaginal application of BKC is embryo- and fetocidal in the rat at a dose about 143 times higher than that recommended for controlling conception in women.

  15. Non-specific vaginitis or vaginitis of undetermined aetiology.

    PubMed

    Faro, S; Phillips, L E

    1987-01-01

    Vaginitis is a complex syndrome that is probably the most common outpatient disease seen by the gynaecologist. The specific aetiologies of vaginitis are many. One of the most common entities, however, is "non-specific vaginitis" which can be subdivided into: Gardnerella vaginitis, anaerobic vaginosis, and vaginitis of undetermined aetiology. The role of Gardnerella as a causative agent for vaginitis has been studied in depth but its specific role remains controversial. Anaerobic vaginosis can be diagnosed by noting on microscopic examination the presence of clue cells, free-floating bacteria and numerous white blood cells (WBC's). Culturing an aliquot of the vaginal discharge reveals a high number of anaerobes. In addition, this condition responds to antibiotics effective against anaerobes, e.g., metronidazole. Vaginitis of undetermined aetiology is more complex and is characterized by a purulent vaginal discharge, a pH of 4.0-4.6, numerous WBC's, and a high concentration of bacteria. The microbiology of this vaginitis includes many facultative Gram-negative rods and Gram-positive cocci. Anaerobes may be present but do not make up a large component of the endogenous microflora. This condition does not respond to the usual antibiotic therapies employed in treating bacterial vaginitis. Since this condition appears to be primarily an inflammatory reaction, it may be responsive to topical antiinflammatory agents such as benzydamine.

    2013-08-01

    To provide an overview of the available data from clinical studies of vaginal conditions in women who use a vaginal ring as a contraceptive. A systematic review of the literature. Millions of women have already used the ethylene vinyl acetate vaginal ring that releases ethinylestradiol and etonogestrel for contraception. Because of its small size, more than four out of five women using the ring report that they do not feel it, even during sexual intercourse. No colposcopic or cytological changes have been observed in users, although approximately 10% have increased vaginal discharge. While in vitro studies have shown adhesion of Candida yeasts to the vaginal ring surface, clinical studies have not demonstrated a greater incidence of Candida infections compared to users of equivalent oral contraceptives. Some clinical studies suggest a lower incidence of bacterial vaginosis. No interaction exists between concomitant use of the vaginal ring and other drugs or products for vaginal use. The use of a contraceptive vaginal ring does not alter the vaginal ecosystem and therefore does not substantially affect vaginal health.

    Purpose: To review the experience of a large cancer center with radiotherapy (RT) patients bearing implantable cardiac defibrillators (ICDs) to propose some preliminary care guidelines as we learn more about the devices and their interaction with the therapeutic radiation environment. Methods and Materials: We collected data on patients with implanted ICDs treated with RT during a 2.5-year period at any of the five Memorial Sloan-Kettering clinical campuses. Information regarding the model, location, and dose detected from the device, as well as the treatment fields, fraction size, and treatment energy was collected. During this time, a new management policy for thesemore » patients had been implemented requiring treatment with low-energy beams (6 MV) and close surveillance of the patients in partnership with their electrophysiologist, as they received RT. Results: During the study period, 33 patients were treated with an ICD in place. One patient experienced a default of the device to its initial factory setting that was detected by the patient hearing an auditory signal from the device. This patient had initially been treated with a 15-MV beam. After this episode, his treatment was replanned to be completed with 6-MV photons, and he experienced no further events. Conclusion: Patients with ICDs and other implanted computer-controlled devices will be encountered more frequently in the RT department, and proper management is important. We present a policy for the safe treatment of these patients in the radiation oncology environment.« less

    There is a lack of literature examining the dosimetric implications of irradiating breast implants and expanders with internal ports inserted at the time of mastectomy. To determine whether the presence of breast expanders with port in saline or silicone implants affect the dose uniformity across the breast when irradiated with various photon and electron energies. One tissue-equivalent torso phantom with overlying tissue expanders in saline or silicone implants were irradiated using tangential fields with 6 MV and 18 MV photons and 9 MeV and 12 MeV electrons. All dose measurements were performed using thermoluminescent dosimeters (TLDs). The TLDs were arranged around the port and the perimeters of either the expander, or saline or silicone implant. Comparisons of measured radiation doses, and between the expected and measured doses of radiation from the TLDs on each prosthesis, were performed. Data were analyzed using two-tailed t tests. There were no differences in TLD measurements between the expander and the saline implant for all energy modalities, and for the expected versus actual measurements for the saline implant. Higher than anticipated measurements were recorded for a significant number of TLD positions around the silicone implants. Radiation doses around saline implants or expanders with internal port were unaltered, whereas dose recordings for silicone implants were higher than predicted in the present laboratory/ex vivo study.

    To explore the biocompatibility of the poly-lactide-co-glycolide (PLGA)/collagen type I scaffold with rat vaginal epithelial cells, and the feasibility of using PLGA/collagen type I as scaffold to reconstruct vagina by the tissue engineering. PLGA/collagen type I scaffold was prepared with PLGA covered polylysine and collagen type I. The vaginal epithelial cells of Sprague Dawley rat of 10-12 weeks old were cultured by enzyme digestion method. The vaginal epithelial cells of passage 2 were cultured in the leaching liquor of scaffold for 48 hours to detect its cytotoxicity by MTT. The vaginal epithelial cells were inoculated on the PLGA/collagen type I scaffold (experimental group) and PLGA scaffold (control group) to calculate the cell adhesion rate. Epithelial cells-scaffold complexes were implanted subcutaneously on the rat back. At 2, 4, and 8 weeks after implantation, the epithelial cells-scaffold complexes were harvested to observe the cell growth by HE staining and immunohistochemical analysis. The epithelial cells-scaffold complexes were transplanted to reconstruct vagina in 6 rats with vaginal defect. After 3 and 6 months, the vaginal length was measured and the appearance was observed. The neovagina tissues were harvested for histological evaluation after 6 months. The epithelial cells grew and proliferated well in the leaching liquor of PLGA/collagen type I scaffold, and the cytotoxicity was at grade 1. The cell adhesion rate on the PLGA/collagen type I scaffold was 71.8%±9.2%, which significantly higher than that on the PLGA scaffold (63.4%±5.7%) (t=2.195, P=0.005). The epithelial cells could grow and adhere to the PLGA/collagen type I scaffolds. At 2 weeks after implanted subcutaneously, the epithelial cells grew and proliferated in the pores of scaffolds, and the fibroblasts were observed. At 4 weeks, 1-3 layers epithelium formed on the surface of scaffold. At 8 weeks, the epithelial cells increased and arranged regularly, which formed the membrane

    The aim of this study was to evaluate the effect of metallic implants on the dose calculation for radiation therapy in patients with metallic implants and to find a way to reduce the error of dose calculation. We made a phantom in which titanium implants were inserted into positions similar to the implant positions in spinal posterior/posterolateral fusion. We compared the calculated dose of the treatment planning systems with the measured dose in the treatment equipment. We used 3 kinds of computed tomography (CT) (kilovoltage CT, extended-scaled kilovoltage CT, and megavoltage CT) and 3 kinds of treatment equipment (ARTISTE, TomoTherapymore » Hi-Art, and Cyberknife). For measurement of doses, we used an ionization chamber and Gafchromic external beam therapy film. The absolute doses that were measured using an ionization chamber at the isocenter in the titanium phantom were on average 1.9% lower than those in the reference phantom (p = 0.002). There was no statistically significant difference according to the kinds of CT images, the treatment equipment, and the size of the targets. As the distance from the surface of the titanium implants became closer, the measured doses tended to decrease (p < 0.001), and this showed a statistically significant difference among the kinds of CT images: the effect of metallic implants was less in the megavoltage CT than in the kilovoltage CT or the extended-scaled kilovoltage CT. The error caused by the titanium implants was beyond a clinically acceptable range. To reduce the error of dose calculation, we suggest that the megavoltage CT be used for planning. In addition, it is necessary to consider the distance between the titanium implants and the targets or the organs at risk to prescribe the dose for the target and the dose constraint for the organs at risk.« less

    Studies with an estrogen-dependent murine model of vaginal candidiasis suggest that local cell-mediated immunity (CMI) is more important than systemic CMI for protection against vaginitis. The present study, however, showed that, compared to uninfected mice, little to no change in the percentage or types of vaginal T cells occurred during a primary vaginal infection or during a secondary vaginal infection where partial protection was observed. Furthermore, depletion of polymorphonuclear leukocytes (PMN) had no effect on infection in the presence or absence of pseudoestrus. These results indicate a lack of demonstrable effects by systemic CMI or PMN against vaginitis and suggest that if local T cells are important, they are functioning without showing significant increases in numbers within the vaginal mucosa during infection.

    1992-01-01

    An apparatus for angle-resolved, wavelength-dispersive x-ray fluorescence spectroscopy with synchrotron radiation has been built and tested at the beam line BN2 of the Bonn electron stretcher and accelerator (ELSA). The apparatus is to be used for nondestructive depth profile analysis of ion-implanted semiconductors as part of the multinational Versailles Project of Advanced Materials and Standards (VAMAS) project on ion-implanted reference materials. In particular, the centroid depths of depth profiles of various implants is to be determined by use of the angle-resolved signal ratio technique. First results of measurements on implants of phosphorus (100 keV, 1016 cm-2) and sulfur (200 keV, 1014 cm-2) in silicon wafers using ``white'' synchrotron radiation are presented and suggest that it should be generally possible to measure the centroid depth of an implant at dose densities as low as 1014 cm-2. Some of the apparative and technical requirements are discussed which are peculiar to the use of synchrotron radiation in general and to the use of nonmonochromatized radiation in particular.

Cs-131, which has higher dose rate is being used to treat brain, head and/or neck cancers in our clinic, therefore, we chose to monitor the dose received by surgeons during the extensive procedure. The aims of this work are to assess the level of radiation exposure to surgeons and the instantaneous exposure at bedside and 1 m from patients. Methods: Ten patients received Cs-131 implants for recurrent brain,head and/or neck cancer; the median implanted activity, number of implanted seedsmore » and prescription dose at 0.5 cm from the perpendicular plane of the implant were: 54.3 mCi (14.52 – 77); 19 (4 – 24) and 60 Gy (range 42 – 60) respectively. Radiation exposure was recorded at bedside and 1 m from the patient using Victoreen ion chamber (Fluke Biomedical, Cleveland, OH). Exposure to surgeons was measured using TLD (Mirion Technologies (GDS), Inc., USA). Results: The median equivalent dose rate at 1 m and bedside immediately following implantation were 1.49×10-2 mSv/h (8.77×10-3–2.63×10-2) and 7.76×10-2 mSv/h (3.1×10-2– 1.53×10-1) respectively. Median equivalent dose to surgeons’ hands was 0.60 mSv (0.33 – 1.48) and no doses were detected for whole-body. Surgical reconstruction for one patient was performed 71 days post-implant and resulted in zero exposure to surgeons. Conclusion: The recorded exposure rates were low when compared with the literature. Post procedure surveys at bed site and 1 m indicated that all patients were within safe limits for discharge (< 0.05 mSv/h at 1 m). However, as a precautionary measure, patients were advised to avoid direct contact with children and pregnant women within four weeks of the implant and stay at least at 3 ft from other people. Surgeons doses were well within occupational dose limits.« less

    Emphysematous vaginitis is a rare condition, characterized by the presence of multiple gas-filled cysts in the vaginal and/or exocervical mucosa. Although its etiology is not completely understood, it is self-limited, with a benign clinical course. Vaginal discharge, sometimes bloody, and pruritus are the most common symptoms. Chronic and acute inflammation can be found, and diseases that impair the immune system and pregnancy have been associated with this condition. A 48-year-old postmenopausal woman, with a history of hysterectomy with several comorbidities, presented with a 4-month history of bloody discharge and vulvar pruritus. Examination showed multiple cystic lesions, 1 to 5 mm, occupying the posterior and right lateral vaginal walls. Speculum examination produced crepitus. Vaginal wet mount was normal, except for diminished lactobacilli; results of Trichomonas vaginalis DNA test and vaginal cultures were negative. Lugol's iodine applied to the vagina was taken up by the intact lesions. Biopsy result showed typical features of emphysematous vaginitis. This is an unusual entity, presenting with common gynecological complaints, and both physicians and pathologists should be aware to prevent misdiagnosis and overtreatment.

    The purpose of this study was to describe a refined method using high-resolution synchrotron radiation microtomography (SRmicro-CT) to evaluate osseointegration and peri-implant bone volume fraction after titanium dental implant insertion. SRmicro-CT is considered gold standard evaluating bone microarchitecture. Its high resolution, high contrast, and excellent high signal-to-noise-ratio all contribute to the highest spatial resolutions achievable today. Using SRmicro-CT at a voxel size of 5 μm in an experimental goat mandible model, the peri-implant bone volume fraction was found to quickly increase to 50% as the radial distance from the implant surface increased, and levelled out to approximately 80% at a distance of 400 μm. This method has been successful in depicting the bone and cavities in three dimensions thereby enabling us to give a more precise answer to the fraction of the bone-to-implant contact compared to previous methods.

    A healthy vaginal microbiota is considered to be significant for maintaining vaginal health and preventing infections. However, certain vaginal bacterial commensal species serve an important first line of defense of the body. Any disruption of this microbial barrier might result in a number of urogenital conditions including aerobic vaginitis (AV) and bacterial vaginosis (BV). The health of the vagina is closely associated with inhabitant microbiota. Furthermore, these microbes maintain a low vaginal pH, prevent the acquisition of pathogens, stimulate or moderate the local innate immune system, and further protect against complications during pregnancies. Therefore, this review will focus on vaginal microbial "health" in the lower reproductive tract of women and on the physiological characteristics that determine the well-being of reproductive health. In addition, we explore the distinct versus shared characteristics of BV and AV, which are commonly associated with increased risk for preterm delivery.

  18. Treatment of postmenopausal vaginal atrophy with 10-μg estradiol vaginal tablets.

    PubMed

    2012-03-01

    Postmenopausal estrogen deficiency can lead to symptoms of urogenital atrophy. Individuals with urogenital atrophy have symptoms that include vaginal dryness, vaginal and vulval irritation, vaginal soreness, pain and burning during urination (dysuria), increased vaginal discharge, vaginal odour, vaginal infections, recurrent urinary tract infections, pain associated with sexual activity (dyspareunia) and vaginal bleeding associated with sexual activity. Despite the frequency and effects of vaginal atrophy symptoms, they are often under-reported and, consequently, under-treated. Therefore, care of a menopausal woman should include a physical assessment of vaginal atrophy and a dialogue between the physician and the patient that explores existing symptoms and their effect on vulvovaginal health, sexuality and quality-of-life issues. The development of the ultra-low-dose 10-µg estradiol vaginal tablets is in line with the requirements of regulatory agencies and women's health societies regarding the use of the lowest effective hormonal dose. Because of its effectiveness and safety profiles, in addition to its minimal systemic absorption, the 10-µg estradiol vaginal tablet can offer greater reassurance to health-care providers and postmenopausal women with an annual estradiol administration of only 1.14 mg.

    Some commercial spaceflight participants (SFPs) may have medical conditions that require implanted medical devices (IMDs), such as cardiac pacemakers, defibrillators, insulin pumps, or similar electronic devices. The effect of space radiation on the function of IMDs is unknown. This review will identify known effects of terrestrial and aviation electromagnetic interference (EMI) and radiation on IMDs in order to provide insight into the potential effects of radiation exposures in the space environment. A systematic literature review was conducted on available literature on human studies involving the effects of EMI as well as diagnostic and therapeutic radiation on IMDs. The literature review identified potential transient effects from EMI and diagnostic radiation levels as low as 10 mGy on IMDs. High-energy, therapeutic, ionizing radiation can cause more permanent device malfunctions at doses as low as 40 mGy. Radiation doses from suborbital flight altitudes and durations are anticipated to be less than those experienced during an average round-trip, cross-country airline flight and are unlikely to result in significant detriment, though longer, orbital flights may expose SFPs to doses potentially harmful to IMD function. Individuals with IMDs should experience few, if any, radiation-related device malfunctions during suborbital flight, but could have problems with radiation exposures associated with longer, orbital flights.

    To evaluate recurrent vaginal cancer treated with vaginal brachytherapy (VBT) using graphic optimization in patients not amenable to surgery and interstitial brachytherapy (ISBT). We retrospectively reviewed the records of 5 patients with recurrent cancer in the vagina that were deemed not to be good candidates for ISBT implant because of medical reasons. All patients received computed tomography/magnetic resonance imaging (CT/MRI) based evaluation in addition to a detailed clinical examination, and were noted to have recurrent nodules in the vagina with size ranging from 10-25 mm. Four of the 5 patients had recurrent disease in the vaginal apex, whereas one patient had recurrence in the lateral vaginal wall. Subsequently, all patients were treated with external beam radiation therapy (EBRT) followed by multichannel vaginal cylinder (MVC)-based VBT using graphic optimization for shaping the isodose to improve the clinical target volume (CTV) coverage, as well as to spare the organs at risk (OAR). The dose to the bladder and rectum with regard to 0.1 cc, 1 cc, and 2 cc were recorded. Median age of the patients was 78 years (range 58-86 years). Thickness of the lesions before VBT ranged from 6-15 mm. All patients were followed up with MRI at 3 months. All patients but one demonstrated complete clinical/ radiological response of the tumor. No patient had any grade III/IV toxicity at 24 months. MVC-based VBT using graphic optimization is safe and yields favorable results if used judiciously.

    To evaluate the clinical features and outcome in girls with a vaginal foreign body. Retrospective review of medical records of 35 girls with a vaginal foreign body seen in an outpatient clinic for paediatric and adolescent gynaecology between 1980 and 2000. The ages ranged from 2.6 to 9.2 years. The most common symptom was blood-stained vaginal discharge/vaginal bleeding (49%). Duration of symptoms varied from 1 day to 2 years. Fifty-four percent of the patients recalled insertion of the foreign object, usually by the girl herself. All but three patients (91%) either recalled insertion of the foreign object and/or had vaginal bleeding or blood-stained or foul-smelling vaginal discharge, and/or visualization or palpation of the foreign body in physical examination. Symptoms resolved after removal of the foreign body followed by a single irrigation with Providon-Iod (Betadine). In the majority of patients a carefully obtained history and physical examination suggest the diagnosis of a vaginal foreign object. The leading symptoms are vaginal bleeding and blood-stained or foul smelling vaginal discharge. Removal of the foreign object followed by a single irrigation with Providon-Iod is the definitive treatment and does not require additional measures.

    Vaginal and cervical swab culture is still very common procedure in our country's everyday practice whereas simple and rapid diagnostic methods have been very rarely used. The aim of this study was to show that the employment of simple and rapid diagnostic tools [vaginal fluid wet mount microscopy (VFWMM), vaginal pH and potassium hydroxide (KOH) test] offers better assessment of vaginal environment than standard microbiologic culture commonly used in Serbia. This prospective study included 505 asymptomatic pregnant women undergoing VFWMM, test with 10% KOH, determination of vaginal pH and standard culture of cervicovaginal swabs. Combining findings from the procedures was used to make diagnoses of bacterial vaginosis (BV) and vaginitis. In addition, the number of polymorphonuclear leukocytes (PMN) was determined in each sample and analyzed along with other findings. Infections with Candida albicans and Trichomonas vaginalis were confirmed or excluded by microscopic examination. In 36 (6%) patients cervicovaginal swab cultures retrieved several aerobes and facultative anaerobes, whereas in 52 (11%) women Candida albicans was isolated. Based on VFWMM findings and clinical criteria 96 (19%) women had BV, 19 (4%) vaginitis, and 72 (14%) candidiasis. Of 115 women with BV and vaginitis, pH 4.5 was found in 5, and of 390 with normal findings 83 (21%) had vaginal pH 4.5. Elevated numbers of PMN were found in 154 (30%) women--in 83 (54%) of them VFWMM was normal. Specificity and sensitivity of KOH test and vaginal pH determination in defining pathological vaginal flora were 95% and 81%, and 79% and 91%, respectively. Cervicovaginal swab culture is expensive but almost non-informative test in clinical practice. The use of simpler and rapid methods as vaginal fluid wet mount microscopy, KOH test and vaginal pH offers better results in diagnosis, and probably in the treatment and prevention of sequels of vaginal infections.

    Polypropylene mesh has been used as a means of reinforcing weak tissues in women with pelvic organ prolapse and stress urinary incontinence. We sought to investigate a potential link between the development of systemic/autoimmune disorders and synthetic polypropylene mesh repairs. New York State Department of Health Statewide Planning and Research Cooperative System data were utilized to conduct this retrospective cohort study. Adult women undergoing surgery for pelvic organ prolapse with vaginally implanted mesh from January 2008 through December 2009 in inpatient and ambulatory surgery settings in New York State were identified. Two separate control cohorts were created to compare outcomes, including a screening colonoscopy cohort and a vaginal hysterectomy cohort for benign gynecologic conditions (without pelvic organ prolapse repair or sling). Patients in the mesh cohort were individually matched to the control cohorts based on demographics, comorbidities, and procedure date. The development of systemic/autoimmune disease was determined before and after matching for 1-year, 2-year, 3-year, and entire follow-up (up to 6 years until December 2014) and differences between groups were evaluated. A total of 2102 patients underwent mesh-based pelvic organ prolapse surgery from January 2008 through December 2009. In the control cohorts, 37,298 patients underwent colonoscopy and 7338 underwent vaginal hysterectomy. When patients were matched based on demographics, comorbidities, and procedure time, mesh-based surgery was not associated with an increased risk of developing autoimmune disease at any of the evaluated time periods. Mesh-based vaginal surgery was not associated with the development of systemic/autoimmune diseases. These data refute claims against mesh as a cause of systemic disease.

    2014-05-01

    Background and Purpose: Brachytherapy in the treatment of locally advanced cervical cancer has changed substantially because of the introduction of combined intracavitary/interstitial applicators and an adaptive target concept, which is the focus of the prospective, multi-institutional EMBRACE study ( (www.embracestudy.dk)) on image-guided adaptive brachytherapy (IGABT). So far, little has been reported about the development of early to late vaginal morbidity in the frame of IGABT. Therefore, the aim of the present EMBRACE analysis was to evaluate the manifestation pattern of vaginal morbidity during the first 2 years of follow-up. Methods and Materials: In total, 588 patients with a median follow-up timemore » of 15 months and information on vaginal morbidity were included. Morbidity was prospectively assessed at baseline, every 3 months during the first year, and every 6 months in the second year according to the Common Terminology Criteria for Adverse Events, version 3, regarding vaginal stenosis, dryness, mucositis, bleeding, fistula, and other symptoms. Crude incidence rates, actuarial probabilities, and prevalence rates were analyzed. Results: At 2 years, the actuarial probability of severe vaginal morbidity (grade ≥3) was 3.6%. However, mild and moderate vaginal symptoms were still pronounced (grade ≥1, 89%; grade ≥2, 29%), of which the majority developed within 6 months. Stenosis was most frequently observed, followed by vaginal dryness. Vaginal bleeding and mucositis were mainly mild and infrequently reported. Conclusion: Severe vaginal morbidity within the first 2 years after definitive radiation (chemo)therapy including IGABT with intracavitary/interstitial techniques for locally advanced cervical cancer is limited and is significantly less than has been reported from earlier studies. Thus, the new adaptive target concept seems to be a safe treatment with regard to the vagina being an organ at risk. However, mild to moderate vaginal

    To evaluate the efficiency of our treatment of vaginal infection for couples included in an IVF program. Microbiologic screening of vaginal flora and semen has been performed one month prior to in vitro fertilization for 951 couples in 2000. Antibiotic treatment was prescribed in case of positive culture. Positive microbial growths were observed from endocervical and vaginal cultures in 218 women (22.9%). The clinical pregnancy rate was 30.29% in the group of patients without growth and 30.27% in the group with positive microbial growth. The implantation rate was significantly diminished in case of bacterial growth: 14.6 compared to 19.3% (P <0.02) for sterile endocervical culture. Five main bacterial species were found at the cervical level: Candida albicans (69 cases), Ureaplasma urealyticum (49 cases), Gardnerella vaginalis (43 cases), Streptococcus B or D (24 cases) and Escherichia coli (22 cases). Positive cultures from both vagina and semen were observed for 77 couples whose clinical pregnancy rate was 19.5 vs 36.2% in case of vaginal infection alone (P <0.01) with a spontaneous miscarriage rate of 46.7 compared to 17.6% (P <0.01). Endocervical microorganisms, even treated with adapted antibiotics, may affect embryonic implantation. Positive culture from both female and male partner may enhance this negative effect. In this case, the best strategy would be to cancel the IVF treatment.

  11. Radiation control in the intensive care unit for high intensity iridium-192 brain implants

    Sewchand, W.; Drzymala, R.E.; Amin, P.P.

    A bedside lead cubicle was designed to minimize the radiation exposure of intensive care unit staff during routine interstitial brain irradiation by removable, high intensity iridium-192. The cubicle shields the patient without restricting intensive care routines. The design specifications were confirmed by exposure measurements around the shield with an implanted anthropomorphic phantom simulating the patient situation. The cubicle reduces the exposure rate around an implant patient by as much as 90%, with the exposure level not exceeding 0.1 mR/hour/mg of radium-equivalent /sup 192/Ir. Evaluation of data accumulated for the past 3 years has shown that the exposure levels of individualmore » attending nurses are 0.12 to 0.36 mR/mg of radium-equivalent /sup 192/Ir per 12-hour shift. The corresponding range for entire nursing teams varies between 0.18 and 0.26. A radiation control index (exposure per mg of radium-equivalent /sup 192/Ir per nurse-hour) is thus defined for individual nurses and nursing teams; this index is a significant guide to the planning of nurse rotations for brain implant patients with various /sup 192/Ir loads. The bedside shield reduces exposure from /sup 192/Ir implants by a factor of about 20, as expected, and the exposure from the lower energy radioisotope iodine-125 is barely detectable.« less

    This study explores the application of conventional micro tomography (μCT) and synchrotron radiation (SR) based μCT to evaluate the bone around titanium dental implants. The SR experiment was performed at beamline W2 of HASYLAB at DESY using a monochromatic X-ray beam of 50 keV. The testing material consisted of undecalcified bone segments harvested from the upper jaw of a macaca fascicularis monkey each containing a titanium dental implant. The results from the two different techniques were qualitatively compared with conventional histological sections examined under light microscopy. The SR-based μCT produced images that, especially at the bone-implant interface, are less noisy and sharper than the ones obtained with conventional μCT. For the proper evaluation of the implant-bone interface, only the SR-based μCT technique is able to display the areas of bony contact and visualize the true 3D structure of bone around dental implants correctly. This investigation shows that both conventional and SR-based μCT scanning techniques are non-destructive methods, which provide detailed images of bone. However with SR-based μCT it is possible to obtain an improved image quality of the bone surrounding dental implants, which display a level of detail comparable to histological sections. Therefore, SR-based μCT scanning could represent a valid, unbiased three-dimensional alternative to evaluate osseointegration of dental implants

    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 themore » 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.« less

    Vulvovaginal candidiasis is a mucosal infection affecting many women, but the immune mechanisms operating against Candida albicans at the mucosal level remain unknown. A rat model was employed to further characterize the contribution of B and T cells to anti-Candida vaginal protection. Particularly, the protective role of vaginal B cells was studied by means of adoptive transfer of vaginal CD3(-) CD5(+) IgM(+) cells from Candida-immunized rats to naïve animals. This passive transfer of B cells resulted into a number of vaginal C. albicans CFU approximately 50% lower than their controls. Sorted CD3(-) CD5(+) IgM(+) vaginal B lymphocytes from Candida-infected rats proliferated in response to stimulation with an immunodominant mannoprotein (MP) antigen of the fungus. Importantly, anti-MP antibodies and antibody-secreting B cells were detected in the supernatant and cell cultures, respectively, of vaginal B lymphocytes from infected rats incubated in vitro with vaginal T cells and stimulated with MP. No such specific antibodies were found when using vaginal B cells from uninfected rats. Furthermore, inflammatory and anti-inflammatory cytokines, such as interleukin-2 (IL-2), IL-6 and IL-10, were found in the supernatant of vaginal B cells from infected rats. These data are evidence of a partial anti-Candida protective role of CD3(-) CD5(+) IgM(+) vaginal B lymphocytes in our experimental model.

    The knowledge about the normal and abnormal vaginal microbiome has changed over the last years. Culturing techniques are not suitable any more for determination of a normal or abnormal vaginal microbiota. Non culture-based modern technologies revealed a complex and dynamic system mainly dominated by lactobacilli.The normal and the abnormal vaginal microbiota are complex ecosystems of more than 200 bacterial species influenced by genes, ethnic background and environmental and behavioral factors. Several species of lactobacilli per individuum dominate the healthy vagina. They support a defense system together with antibacterial substances, cytokines, defensins and others against dysbiosis, infections and care for an normal pregnancy without preterm birth.The numbers of Lactobacillus (L.) iners increase in the case of dysbiosis.Bacterial vaginosis (BV) - associated bacteria (BVAB), Atopobium vaginae and Clostridiales and one or two of four Gardnerella vaginalis - strains develop in different mixtures and numbers polymicrobial biofilms on the vaginal epithelium, which are not dissolved by antibiotic therapies according to guidelines and, thus, provoke recurrences.Aerobic vaginitis seems to be an immunological disorder of the vagina with influence on the microbiota, which is here dominated by aerobic bacteria (Streptococcus agalactiae, Escherichia coli). Their role in AV is unknown.Vaginal or oral application of lactobacilli is obviously able to improve therapeutic results of BV and dysbiosis.

    Cancer-associated fibroblasts (CAFs) are abundantly present in solid tumors and affect tumorigenesis and therapeutic responses. In the context of clinical radiotherapy, the impact of irradiated CAFs to treatment outcomes is largely unexplored. Aiming at improving radiotherapy efficacy, we have here explored the effect of radiation on the inherent pro-tumorigenic capacity of CAFs in animals. Ionizing radiation was delivered to cultured CAFs as single-high or fractionated doses. Tumor development was compared in mice receiving A549 lung tumor cells admixed with irradiated or control CAFs. Biological mechanisms behind tumor growth regulation were investigated by quantitative histology and immunohistochemistry. Viability assessments confirmed that irradiated CAFs are fully functional prior to implantation. However, the enhanced tumorigenic effect observed in tumors co-implanted with control CAFs was abrogated in tumors established with irradiated CAFs. Experiments to ascertain fate of implanted fibroblasts showed that exogenously administered CAFs reside at the implantation site for few days, suggesting that tumor growth regulation from admixed CAFs take place during initial tumor formation. Our work demonstrate that irradiated CAFs lose their pro-tumorigenic potential in vivo, affecting angiogenesis and tumor engraftment. This finding propose a previously unknown advantageous effect induced by radiotherapy, adding to the direct cytotoxic effects on transformed epithelial cells.

    Immediate implant-based breast reconstruction followed by postmastectomy radiation therapy (PMRT) is controversial because of the risk of compromised treatment plans and concerns regarding cosmetic outcomes. We evaluated the effects of immediate direct-to-implant breast reconstruction with anatomical implants on the quality of PMRT delivered by 3-dimensional conformal radiotherapy (3D-CRT). In this retrospective, single-institution study, patients who had undergone reconstruction with direct anatomic implant, performed by a single surgeon, received 3D-CRT between 2008 and 2013. For each patient, 2 plans (including or excluding internal mammary nodes [IMN]) were created and calculated. The primary end point was the dose distribution among reconstructed breasts,more » heart, lungs, and IMNs, and between right and left breasts. Of 29 consecutive patients, 11 received right-sided and 18 received left-sided PMRT to a total dose of 50 Gy. For plans excluding IMN coverage, mean D{sub mean} for right and left reconstructed breasts was 49.09 Gy (98.2% of the prescribed dose) and 48.51 Gy (97.0%), respectively. For plans including IMNs, mean D{sub mean} was 49.15 Gy (98.3%) for right and 48.46 Gy (96.9%) for left reconstructed breasts; the mean IMN D{sub mean} was 47.27 Gy (right) and 47.89 Gy (left). Heart D{sub mean} was below 1.56 Gy for all plans. Mean total lung volume receiving a dose of ≥ 20 Gy was 13.80% to 19.47%. PMRT can be delivered effectively and safely by 3D-CRT after direct-to-implant breast reconstruction with anatomical implants, even if patients require IMN treatment.« less

    Research indicated that: (i) vaginal orgasm (induced by penile-vaginal intercourse [PVI] without concurrent clitoral masturbation) consistency (vaginal orgasm consistency [VOC]; percentage of PVI occasions resulting in vaginal orgasm) is associated with mental attention to vaginal sensations during PVI, preference for a longer penis, and indices of psychological and physiological functioning, and (ii) clitoral, distal vaginal, and deep vaginal/cervical stimulation project via different peripheral nerves to different brain regions. The aim of this study is to examine the association of VOC with: (i) sexual arousability perceived from deep vaginal stimulation (compared with middle and shallow vaginal stimulation and clitoral stimulation), and (ii) whether vaginal stimulation was present during the woman's first masturbation. A sample of 75 Czech women (aged 18-36), provided details of recent VOC, site of genital stimulation during first masturbation, and their recent sexual arousability from the four genital sites. The association of VOC with: (i) sexual arousability perceived from the four genital sites and (ii) involvement of vaginal stimulation in first-ever masturbation. VOC was associated with greater sexual arousability from deep vaginal stimulation but not with sexual arousability from other genital sites. VOC was also associated with women's first masturbation incorporating (or being exclusively) vaginal stimulation. The findings suggest (i) stimulating the vagina during early life masturbation might indicate individual readiness for developing greater vaginal responsiveness, leading to adult greater VOC, and (ii) current sensitivity of deep vaginal and cervical regions is associated with VOC, which might be due to some combination of different neurophysiological projections of the deep regions and their greater responsiveness to penile stimulation. © 2013 International Society for Sexual Medicine.

  2. Management of aerobic vaginitis.

    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. Copyright © 2010 S. Karger AG, Basel.

    We report a case of successful vaginal delivery after vaginal reconstruction with labium minus flaps in a 23-year-old patient with congenital vaginal atresia. The patient primarily presented with amenorrhea and cyclic abdominal pain; transabdominal ultrasonography revealed an enlarged uterus due to hematometra and absence of the lower segment of the vagina. Eight years ago, she had undergone an unsuccessful attempt at canalization at a local hospital. Upon referral to our hospital, she underwent vaginal reconstruction with labium minus flaps. Four months after this procedure, she became pregnant and, subsequently, successfully and safely vaginally delivered a healthy female baby weighing 3250 g at 38 +1 weeks' gestation. The delivery did not involve perineal laceration by lateral episiotomy. To the best of our knowledge, this is the first reported case of successful vaginal delivery at term after vaginal reconstruction with labium minus flaps in a patient with vaginal atresia. © 2017 Japan Society of Obstetrics and Gynecology.

    To define an entity of abnormal vaginal flora: aerobic vaginitis. Observational study. University Hospital Gasthuisberg, Leuven, Belgium. 631 women attending for routine prenatal care or attending vaginitis clinic. Samples were taken for fresh wet mount microscopy of vaginal fluid, vaginal cultures and measurement of lactate, succinate and cytokine levels in vaginal fluid. Smears deficient in lactobacilli and positive for clue cells were considered to indicate a diagnosis of bacterial vaginosis. Aerobic vaginitis was diagnosed if smears were deficient in lactobacilli, positive for cocci or coarse bacilli, positive for parabasal epithelial cells, and/or positive for vaginal leucocytes (plus their granular aspect). Genital complaints include red inflammation, yellow discharge, vaginal dyspareunia. Group B streptococci, escherichia coli, staphylococcus aureus and trichomonas vaginalis are frequently cultured. Vaginal lactate concentration is severely depressed in women with aerobic vaginitis, as in bacterial vaginosis, but vaginal succinate is not produced. Also in contrast to bacterial vaginosis, aerobic vaginitis produces a host immune response that leads to high production of interleukin-6, interleukin-1-beta and leukaemia inhibitory factor in the vaginal fluid. Aerobic vaginitis is associated with aerobic micro-organisms, mainly group B streptococci and E. coli. Its characteristics are different from those of bacterial vaginosis and elicit an important host response. The most severe form of aerobic vaginitis equals desquamative inflammatory vaginitis. In theory, aerobic vaginitis may be a better candidate than bacterial vaginosis as the cause of pregnancy complications, such as ascending chorioamnionitis, preterm rupture of the membranes and preterm delivery.

    Vaginal administration of sildenafil citrate has shown recently to develop efficiently the uterine lining with subsequent successful embryo implantation following in vitro fertilization. The aim of the present study was to develop sildenafil-loaded liposomes coated with bioadhesive polymers for enhanced vaginal retention and improved drug permeation. Three liposomal formulae were prepared by thin-film method using different phospholipid:cholesterol ratios. The optimal liposomal formulation was coated with bioadhesive polymers (chitosan and HPMC). A marked increase in liposomal size and zeta potential was observed for all coated liposomal formulations. HPMC-coated liposomes showed the greater bioadhesion and higher entrapment efficiency than chitosan-coated formulae. The in vitro release studies showed prolonged release of sildenafil from coated liposomes as compared to uncoated liposomes and sildenafil solution. Ex vivo permeation study revealed the enhanced permeation of coated relative to uncoated liposomes. Chitosan-coated formula demonstrated highest drug permeation and was thus selected for further investigations. Transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR) confirmed the successful coating of the liposomes by chitosan. Histopathological in vivo testing proved the efficacy of chitosan-coated liposomes to improve blood flow to the vaginal endometrium and to increase endometrial thickness. Chitosan-coated liposomes can be considered as potential novel drug delivery system intended for the vaginal administration of sildenafil, which would prolong system's retention at the vaginal site and enhance the permeation of sildenafil to uterine blood circulation.

    The purpose of this study was to measure the radiation exposure to operator and patient during cardiac electrophysiology study, radiofrequency catheter ablation and cardiac device implantation procedures and to calculate the allowable number of cases per year. We carried out 9 electrophysiology studies, 40 radiofrequency catheter ablation and 11 cardiac device implantation procedures. To measure occupational radiation dose and dose-area product (DAP), 13 photoluminescence glass dosimeters were placed at eyes (inside and outside lead glass), thyroids (inside and outside thyroid collar), chest (inside and outside lead apron), wrists, genital of the operator (inside lead apron), and 6 of photoluminescence glass dosimeters were placed at eyes, thyroids, chest and genital of the patient. Exposure time and DAP values were 11.7 ± 11.8 min and 23.2 ± 26.2 Gy cm2 for electrophysiology study; 36.5 ± 42.1 min and 822.4 ± 125.5 Gy cm2 for radiofrequency catheter ablation; 16.2 ± 9.3 min and 27.8 ± 16.5 Gy cm2 for cardiac device implantation procedure, prospectively. 4591 electrophysiology studies can be conducted within the occupational exposure limit for the eyes (150 mSv), and 658-electrophysiology studies with radiofrequency catheter ablation can be carried out within the occupational exposure limit for the hands (500 mSv). 1654 cardiac device implantation procedure can be conducted within the occupational exposure limit for the eyes (150 mSv). The amounts of the operator and patient's radiation exposure were comparatively small. So, electrophysiology study, radio frequency catheter ablation and cardiac device implantation procedures are safe when performed with modern equipment and optimized protective radiation protect equipment.

    We examined the vaginal washings from patients with nonspecific vaginitis (NSV) to seek biochemical markers and possible explanations for the signs and symptoms of this syndrome. Seven amines were identified including methylamine, isobutylamine, putrescine, cadaverine, histamine, tyramine, and phenethylamine. These amines may contribute to the symptoms of NSV and may contribute to the elevated pH of the vaginal discharge. They may also be partly responsible for the "fishy" odor that is characteristic of vaginal discharges from these patients. Among the seven amines, putrescine and cadaverine were the most abundant and were present in all vaginal discharges from each of ten patients before treatment. These amines are produced in vitro during growth of mixed vaginal bacteria in chemically defined medium, presumably by decarboxylation of the corresponding amino acids. We hypothesize the anaerobic vaginal organisms, previously shown to be quantitatively increased in NSV, are responsible for the amine production, because metronidazole inhibited the production of amines by vaginal bacteria in vitro, and Haemophilus vaginalis did not produce amines. H. vaginalis did release high concentrations of pyruvic acid and of amino acids during growth in peptone-starch-dextrose medium, whereas, other vaginal flora consumed both pyruvic acid and amino acids in the same medium during growth. These findings suggest that a symbiotic relationship may exist between H. vaginalis and other vaginal flora in patients with NSV. Images PMID:447831

    Evidence was recently provided for vaginal orgasm, orgasm triggered purely by penile-vaginal intercourse (PVI), being associated with better psychological functioning. Common sex education and sexual medicine approaches might undermine vaginal orgasm benefits. To examine the extent to which women's vaginal orgasm consistency is associated with (i) being told in childhood or adolescence that the vagina was the important zone for inducing female orgasm; (ii) how well they focus mentally on vaginal sensations during PVI; (iii) greater PVI duration; and (iv) preference for above-average penis length.   In a representative sample of the Czech population, 1,000 women reported their vaginal orgasm consistency (from never to almost every time; only 21.9% never had a vaginal orgasm), estimates of their typical foreplay and PVI durations, what they were told in childhood and adolescence was the important zone for inducing female orgasm, their degree of focus on vaginal sensations during PVI, and whether they were more likely to orgasm with a longer than average penis. The association of vaginal orgasm consistency with the predictors noted above. Vaginal orgasm consistency was associated with all hypothesized correlates. Multivariate analysis indicated the most important predictors were being educated that the vagina is important for female orgasm, being mentally focused on vaginal sensations during PVI, and in some analyses duration of PVI (but not foreplay) and preferring a longer than average penis. Focusing attention on penile-vaginal sensation supports vaginal orgasm and the myriad benefits thereof. Brody S, and Weiss P.

    For over a century it has been well documented that bacteria in the vagina maintain vaginal homeostasis, and that an imbalance or dysbiosis may be associated with poor reproductive and gynecologic health outcomes. Vaginal microbiota are of particular significance to postmenopausal women and may have a profound effect on vulvovaginal atrophy, vaginal dryness, sexual health and overall quality of life. As molecular-based techniques have evolved, our understanding of the diversity and complexity of this bacterial community has expanded. The objective of this review is to compare the changes that have been identified in the vaginal microbiota of menopausal women, outline alterations in the microbiome associated with specific menopausal symptoms, and define how hormone replacement therapy impacts the vaginal microbiome and menopausal symptoms; it concludes by considering the potential of probiotics to reinstate vaginal homeostasis following menopause. This review details the studies that support the role of Lactobacillus species in maintaining vaginal homeostasis and how the vaginal microbiome structure in postmenopausal women changes with decreasing levels of circulating estrogen. In addition, the associated transformations in the microanatomical features of the vaginal epithelium that can lead to vaginal symptoms associated with menopause are described. Furthermore, hormone replacement therapy directly influences the dominance of Lactobacillus in the microbiota and can resolve vaginal symptoms. Oral and vaginal probiotics hold great promise and initial studies complement the findings of previous research efforts concerning menopause and the vaginal microbiome; however, additional trials are required to determine the efficacy of bacterial therapeutics to modulate or restore vaginal homeostasis.

    2018-06-01

    The results of studying the annealing kinetics of the radiation-induced donor-type defects in boron implanted p-type Hg1‑x Cd x Te (MCT) are presented. The annealing kinetics of the radiation donor centers depend significantly on the dose of B+ ions, that is on the initial level of structural defects generated in the MCT lattice by ion bombardment. The activation energy E A of annealing of donor defects generated by implantation of B+ ions increases with increasing dose and temperature of the post-implantation heat treatment under the SiO2 cap. The smaller the dose and the higher the initial hole concentration in p-MCT, the lower the temperature of a complete annealing of donor centers, which lies in the range 220–275 °C. In the initial stages of the post-implantation heat treatment, primary donor defects are annealed, and then, more stable secondary impurity-defect complexes are annealed. It was established for the first time that the activation energy of the donor defects annealing in bulk crystals and heteroepitaxial structures of MCT has two clearly pronounced regions: at low temperatures 90–130 °C, E A = 0.06 eV and at Т = 150–250 °C, E A = 0.71–0.86 eV.

    Zinc is known to play a relevant role in growth and development; it has stimulatory effects on in vitro and in vivo bone formation and an inhibitory effect on in vitro osteoclastic bone resorption. The inorganic component of the bone tissue is nonstoichiometric apatite; changes in the composition of hidroxyapatite are subject of studies in order to improve the tissue response after implantation. The objective of this study was to investigate the effect of 0.5% zinc-containing hydroxyapatite in comparison to hydroxyapatite on osseous repair of rabbit's tibia. Cylinders (2x6 mm) of both materials were produced according to the specification ofmore » the International Organization for Standardization. Ethics Commission on Teaching and Research in Animals approved this project (HUAP-195/06). Fifteen White New Zealand rabbits were submitted to general anesthesia and two perforations (2 mm) were made in each tibia for implantation of zinc-containing hydroxyapatite cylinders (left tibia) and hydroxyapatite cylinders (right tibia). After 1, 2 and 4 weeks, the animals were killed and one fragment of each tibia with the cylinder was collected and embedded in a methacrylate-based resin and cut into slices (approx200 {mu}m thickness), parallel to the implant's long axis with a precision diamond saw for Synchrotron Radiation X-ray Microfluorescence investigation. The accomplishment of the standard procedures helped the planning, execution and the comparative analysis of the results.

    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.more » 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.« less

    This study was conducted to evaluate the therapeutic effects of vaginal royal jelly and vaginal estrogen on quality of life and vaginal atrophy in postmenopausal women. This double-blind randomized controlled clinical trial was carried out at gynecology and obstetrics clinics of Hajar Hospital of Shahrekord University of Medical Sciences (Iran) from January 2013 to January 2014. The study was conducted on married postmenopausal women between 50 and 65 years old. Of 120 patients, 30 individuals were excluded based on the exclusion criteria, and 90 women were randomly distributed into three groups of 30 royal jelly vaginal cream 15%, vaginal Premarin, and placebo (lubricant), for three months. At the beginning and the end of the study, quality of life and vaginal cytology assay were evaluated. Data were analyzed by SPSS Version 11. Vaginal cream of royal jelly is significantly more effective than vaginal cream of Premarin and lubricant in improvement of quality of life in postmenopausal women (p<0.05). Moreover, Pap smear results showed that vaginal atrophy in vaginal Premarin group was lower than the other groups (p<0.001), and there was no significant difference between lubricant and royal jelly groups (p=0.89). Administration of vaginal royal jelly was effective in quality-of-life improvement of postmenopausal women. Given to the various properties of royal jelly and its effectiveness on quality of life and vaginal atrophy in postmenopausal women, further studies are recommended for using =royal jelly in improving menopausal symptoms.

    Lactobacilli species that are better adapted to vaginal environment of women may colonize better and offer protection against vaginal pathogenic bacteria. In this study, the distribution of common Lactobacillus species was investigated in pregnant women. Sixty seven pregnant women were included in the study and vaginal samples were collected for Gram staining. Women were classified as normal vaginal flora, intermediate flora and bacterial vaginosis (BV) based on Nugent's score. Vaginal samples were also collected for the identification of Lactobacillus spp. by multiplex polymerase chain reaction (PCR) profiling of 16S rDNA amplification method. Lactobacillus crispatus (100%) was the most predominant Lactobacillus spp. present in pregnant women with normal flora, followed by L. iners (77%), L. jensenii (74%) and L. helveticus (60%). While, L. iners was commonly present across groups in women with normal, intermediate or BV flora, L. crispatus, L. jensenii and L. helveticus decreased significantly as the vaginal flora changed to intermediate and BV. In women with BV, except L. iners other species of lactobacilli was less frequently prevalent. Species such as L. rhamnosus, L. fermentum, L. paracasei and L. casei were not detected in any vaginal sample. L. crispatus, L. jensinii and L. helveticus were predominant species in women with normal flora. L. crispatus alone or in combination with L. jensinii and L. helveticus may be evaluated for probiotic properties for the prevention and treatment of BV.

    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

    To broaden the current understanding of radiation exposure and risk and to provide concrete evidence of radiation safety related to (125)I seed implantation. Direct radiation exposure measurements were obtained from dosimeters provided to 25 patients who underwent (125)I seed implantation, along with their family members. The estimated lifetime exposure dose and the precaution time for holding children near the patient's chest were calculated in two study periods. During the first and second study period, the mean estimated lifetime exposure doses were, respectively, 7.61 (range: 0.45, 20.21) mSv and 6.84 (range: 0.41, 19.20) mSv for patients, and 0.19 (range: 0.02, 0.54) mSv and 0.25 (range: 0.04, 1.00) mSv for family members. The mean ratios of first and second period measurements were 1.05 (range: 0.44, 3.18) for patients and 1.82 (range: 0.21, 7.04) for family members. The corresponding absolute differences between first and second period measurements were -0.77 (range: -11.40, 7.63) mSv and 0.06 (range: -0.26, 0.79) mSv, respectively. Assuming a dose limit of 1 mSv, the precaution times for holding a child every day of the first and second periods were 250.9 (range: 71.3, 849.4) min and 275.2 (range: 75.0, 883.4) min, respectively. Assuming a dose limit of 0.5 mSv, the corresponding precaution times were 179.0 (range: 35.6, 811.5) min and 178.9 (range: 37.5, 1131.8) min, respectively. Our study demonstrated low radiation exposures to family members of patients undergoing (125)I prostate implantation. It was clear that (125)I seed implantation did not pose a threat to the safety of family members. Copyright © 2016 American Brachytherapy Society. Published by Elsevier Inc. All rights reserved.

  6. Vaginitis: diagnosis and management.

    PubMed

    Faro, S

    The various conditions that give rise to vaginitis include specific and nonspecific entities, such as candidiasis, trichomoniasis, bacterial vaginosis, group B streptococcal vaginitis, purulent vaginitis, volvodynia, and vestibulitis. The patient with chronic vaginitis usually develops this condition because of a misdiagnosis. It is critical that patients who have chronic vaginitis be thoroughly evaluated to determine if there is a specific etiology and whether their condition is recurrent or persistent, or is a reinfection. This also must include obtaining a detailed history, beginning with the patient's best recollection of when she felt perfectly normal. The physician must have an understanding of a healthy vaginal ecosystem and what mechanisms are in place to maintain the equilibrium. The vaginal ecosystem is a complex system of micro-organisms interacting with host factors to maintain its equilibrium. The endogenous microflora consists of a variety of bacteria, which include aerobic, facultative and obligate anaerobic bacteria. These organisms exist in a commensal, synergistic or antagonistic relationship. Therefore, it is important to understand what factors control the delicate equilibrium of the vaginal ecosystem, and which factors, both endogenous and exogenous, can disrupt this system. It is also important for the physician to understand that when a patient has symptoms of vaginitis it is not always due to an infectious etiology. There are situations in which an inflammatory reaction occurs but the specific etiology may not be determined. Thus, it is important that the physician not rush through the history or the examination.

    This review presents and applies fundamental mass transport theory describing the diffusion and convection driven mass transport of drugs to the vaginal environment. It considers sources of variability in the predictions of the models. It illustrates use of model predictions of microbicide drug concentration distribution (pharmacokinetics) to gain insights about drug effectiveness in preventing HIV infection (pharmacodynamics). The modeling compares vaginal drug distributions after different gel dosage regimens, and it evaluates consequences of changes in gel viscosity due to aging. It compares vaginal mucosal concentration distributions of drugs delivered by gels vs. intravaginal rings. Finally, the modeling approach is used to compare vaginal drug distributions across species with differing vaginal dimensions. Deterministic models of drug mass transport into and throughout the vaginal environment can provide critical insights about the mechanisms and determinants of such transport. This knowledge, and the methodology that obtains it, can be applied and translated to multiple applications, involving the scientific underpinnings of vaginal drug distribution and the performance evaluation and design of products, and their dosage regimens, that achieve it.

    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 ofmore » 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.« less

    Vulvovaginal candidiasis is one of the most common infections of the genital tract in women that causes many complications. Therefore, we examined the clinical effect of ginger cream along with clotrimazole compared to vaginal clotrimazole alone in this study. This double-blind clinical trial was conducted on 67 women admitted to the Gynecology Clinic of Hajar Hospital with vaginal candidiasis. The patients were divided randomly into two groups of 33 and 34 people. The diagnosis was made according to clinical symptoms, wet smear, and culture. Ginger-clotrimazole vaginal cream 1% and clotrimazole vaginal cream 1% were administered to groups 1 and 2, respectively, once a day for 7 days and therapeutic effects and symptoms were evaluated in readmission. Data analysis was performed using SPSS version 22, t -test and Chi-square. The mean value of variables itching ( P > 0.05), burning ( P > 0.05), and cheesy secretion ( P < 0.05) in users of ginger-clotrimazole was less than the other group after the treatment. Recurrence in clotrimazole group was 48.5% and in ginger-clotrimazole group 51.2% during the 1-month follow-up with no significant difference. Study results showed that cream containing ginger and clotrimazole 1% was more effective and may be more useful than the clotrimazole to treat vaginal candidiasis.

    Tension-free vaginal tape (TVT) procedures are used for the treatment of stress urinary incontinence in women. The procedures with synthetic materials can have a risk of vaginal erosion. We experienced transobturator suburethral sling (TOT) tape-induced vaginal erosion and report the efficacy of a vaginal mucosal covering technique. A total of 560 female patients diagnosed with stress urinary incontinence underwent TOT procedures at our hospital between January 2005 and August 2009. All patients succeeded in follow-ups, among which 8 patients (mean age: 50.5 years) presented with vaginal exposure of the mesh. A vaginal mucosal covering technique was performed under local anesthesia after administration of antibiotics and vaginal wound dressings for 3-4 days. Seven of the 8 patients complained of persistent vaginal discharge postoperatively. Two of the 8 patients complained of dyspareunia of their male partners. The one remaining patient was otherwise asymptomatic, but mesh erosion was discovered at the routine follow-up visit. Six of the 8 patients showed complete mucosal covering of the mesh after the operation (mean follow-up period: 16 moths). Vaginal mucosal erosion recurred in 2 patients, and the mesh was then partially removed. One patient had recurrent stress urinary incontinence. Vaginal mucosal covering as a sling preservation with continued patient continence may be a feasible and effective option for the treatment of vaginal exposure of mesh after TOT tape procedures.

  14. Lactobacilli Dominance and Vaginal pH: Why Is the Human Vaginal Microbiome Unique?

    The human vaginal microbiome is dominated by bacteria from the genus Lactobacillus , which create an acidic environment thought to protect women against sexually transmitted pathogens and opportunistic infections. Strikingly, lactobacilli dominance appears to be unique to humans; while the relative abundance of lactobacilli in the human vagina is typically >70%, in other mammals lactobacilli rarely comprise more than 1% of vaginal microbiota. Several hypotheses have been proposed to explain humans' unique vaginal microbiota, including humans' distinct reproductive physiology, high risk of STDs, and high risk of microbial complications linked to pregnancy and birth. Here, we test these hypotheses using comparative data on vaginal pH and the relative abundance of lactobacilli in 26 mammalian species and 50 studies ( N = 21 mammals for pH and 14 mammals for lactobacilli relative abundance). We found that non-human mammals, like humans, exhibit the lowest vaginal pH during the period of highest estrogen. However, the vaginal pH of non-human mammals is never as low as is typical for humans (median vaginal pH in humans = 4.5; range of pH across all 21 non-human mammals = 5.4-7.8). Contrary to disease and obstetric risk hypotheses, we found no significant relationship between vaginal pH or lactobacilli relative abundance and multiple metrics of STD or birth injury risk ( P -values ranged from 0.13 to 0.99). Given the lack of evidence for these hypotheses, we discuss two alternative explanations: the common function hypothesis and a novel hypothesis related to the diet of agricultural humans. Specifically, with regard to diet we propose that high levels of starch in human diets have led to increased levels of glycogen in the vaginal tract, which, in turn, promotes the proliferation of lactobacilli. If true, human diet may have paved the way for a novel, protective microbiome in human vaginal tracts. Overall, our results highlight the need for continuing research on non

    The near field radiation characteristics of implantable Square Spiral Chip Inductor Antennas (SSCIA) for Bio-Sensors have been measured. Our results indicate that the measured near field relative signal strength of these antennas agrees with simulated results and confirm that in the near field region the radiation field is fairly uniform in all directions. The effects of parameters such as ground-plane, number of turns and microstrip-gap width on the performance of the SSCIA are presented. Furthermore, the SSCIA antenna with serrated ground plane produce a broad radiation pattern, with a relative signal strength detectable at distances within the range of operation of hand-held devices for self-diagnosis.

    To evaluate, feasibility, efficacy and morbidity of laparoscopic artificial urinary sphincter (AUS) implantation in women with severe stress urinary incontinence. Twenty-six women with severe stress urinary incontinence were treated between October 2007 and January 2012 by laparoscopic implantation of an AUS AMS 800 (American medical Systems, Inc., Minnetonka, Minnesota). For 18 patients AUS was primary implanted and, for eight, AUS was revised for a mechanical failure. Three patients had a concomitant laparoscopic vaginal prolapse repair. Mean value was for age 64 years, BMI 27.8kg/m2, and mean maximal urethral closure pressure was 26.75cm of water. Most of the patients (88%) had a history of pelvic or incontinence surgery. The study was a retrospective analysis of operative parameters, complications and functional results. Three conversions in open surgery and five bladder injuries were described. Mean operative time was 149 minutes. Bladder catheter was removed at a mean of day 3.8. Mean post-operative stay was 5 days. Early postoperative complications consist in eight acute transient urinary retentions, two pump migrations, and one vaginal injury. Late post-operative complications consist in one vaginal erosion. Explantation of AUS was performed for these last two patients. Mean follow-up was 20 months. Sixteen patients are totally continent, five have a social continence (1 pad/day) and three need more than one pad/day. Our results compare favorably to literature either for laparoscopic or conventional approach with a limited learning curve. Laparoscopic implantation of AUS in women with severe stress urinary incontinence was feasible and efficient. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Preterm birth is the primary cause of infant death worldwide. A short cervix in the second trimester of pregnancy is a risk factor for preterm birth. In specific patient cohorts, vaginal progesterone reduces this risk. Using 16S rRNA gene sequencing, we undertook a prospective study in women at risk of preterm birth (n = 161) to assess (1) the relationship between vaginal microbiota and cervical length in the second trimester and preterm birth risk and (2) the impact of vaginal progesterone on vaginal bacterial communities in women with a short cervix. Lactobacillus iners dominance at 16 weeks of gestation was significantly associated with both a short cervix <25 mm (n = 15, P < 0.05) and preterm birth <34 +0  weeks (n = 18; P < 0.01; 69% PPV). In contrast, Lactobacillus crispatus dominance was highly predictive of term birth (n = 127, 98% PPV). Cervical shortening and preterm birth were not associated with vaginal dysbiosis. A longitudinal characterization of vaginal microbiota (<18, 22, 28, and 34 weeks) was then undertaken in women receiving vaginal progesterone (400 mg/OD, n = 25) versus controls (n = 42). Progesterone did not alter vaginal bacterial community structure nor reduce L. iners-associated preterm birth (<34 weeks). L. iners dominance of the vaginal microbiota at 16 weeks of gestation is a risk factor for preterm birth, whereas L. crispatus dominance is protective against preterm birth. Vaginal progesterone does not appear to impact the pregnancy vaginal microbiota. Patients and clinicians who may be concerned about "infection risk" associated with the use of a vaginal pessary during high-risk pregnancy can be reassured.

    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. © 2015 by the Society for the Study of Reproduction, Inc.

    We compared survival of neonate white-tailed deer Odocoileus virginianus captured using vaginal-implant transmitters (VITs) and traditional ground searches to determine if capture method affects neonate survival. During winter 2003, 14 adult female radio-collared deer were fitted with VITs to aid in the spring capture of neonates; neonates were captured using VITs (N=14) and traditional ground searches (N=7). Of the VITs, seven (50%) resulted in the location of birth sites and the capture of 14 neonates. However, seven (50%) VITs were prematurely expelled prior to parturition. Predation accounted for seven neonate mortalities, and of these, five were neonates captured using VITs. During summer 2003, survival for neonates captured using VITs one, two, and three months post capture was 0.76 (SE=0.05; N=14), 0.64 (SE=0.07; N=11) and 0.64 (SE=0.08; N=9), respectively. Neonate survival one, two and three months post capture for neonates captured using ground searches was 0.71 (SE=0.11; N=7), 0.71 (SE=0.15; N=5) and 0.71 (SE=0.15; N=5), respectively. Although 71% of neonates that died were captured <24 hours after birth using VITs, survival did not differ between capture methods. Therefore, use of VITs to capture neonate white-tailed deer did not influence neonate survival. VITs enabled us to capture neonates in dense habitats which would have been difficult to locate using traditional ground searches.

    Reconstructive surgery for pelvic organ prolapse is plagued with high failure rates possibly due to impaired healing or regeneration of the vaginal wall. Here, we tested the hypothesis that postoperative administration of local estrogen, direct injection of mesenchymal stem cells (MSCs), or both lead to improved wound healing of the injured vagina in a menopausal rat model. Ovariectomized rats underwent surgical injury to the posterior vaginal wall and were randomized to treatment with placebo (n = 41), estrogen cream (n = 47), direct injection of MSCs (n = 39), or both (n = 43). MSCs did not survive after injection and had no appreciable effects on healing of the vaginal wall. Acute postoperative administration of vaginal estrogen altered the response of the vaginal wall to injury with decreased stiffness, decreased collagen content, and decreased expression of transcripts for matrix components in the stromal compartment. Conversely, vaginal estrogen resulted in marked proliferation of the epithelial layer and increased expression of genes related to epithelial barrier function and protease inhibition. Transcripts for genes involved in chronic inflammation and adaptive immunity were also down-regulated in the estrogenized epithelium. Collectively, these data indicate that, in contrast to the reported positive effects of preoperative estrogen on the uninjured vagina, acute administration of postoperative vaginal estrogen has adverse effects on the early phase of healing of the stromal layer. In contrast, postoperative estrogen plays a positive role in healing of the vaginal epithelium after injury.

Methods: Ovariectomized rats underwent surgical injury to the posterior vaginal wall and were randomized to treatment with placebo (n = 41), estrogen cream (n = 47), direct injection of MSCs (n = 39), or both (n = 43). Results: MSCs did not survive after injection and had no appreciable effects on healing of the vaginal wall. Acute postoperative administration of vaginal estrogen altered the response of the vaginal wall to injury with decreased stiffness, decreased collagen content, and decreased expression of transcripts for matrix components in the stromal compartment. Conversely, vaginal estrogen resulted in marked proliferation of the epithelial layer and increased expression of genes related to epithelial barrier function and protease inhibition. Transcripts for genes involved in chronic inflammation and adaptive immunity were also down-regulated in the estrogenized epithelium. Conclusions: Collectively, these data indicate that, in contrast to the reported positive effects of preoperative estrogen on the uninjured vagina, acute administration of postoperative vaginal estrogen has adverse effects on the early phase of healing of the stromal layer. In contrast, postoperative estrogen plays a positive role in healing of the vaginal epithelium after injury. PMID:28169915

    New X-ray technology providing new image processing techniques may reduce radiation exposure. The aim of this study was to quantify this radiation exposure reduction for patients during pacemaker and implantable cardioverter defibrillator (ICD) implantation. In this retrospective study, 1185 consecutive patients who had undergone de novo pacemaker or ICD implantation during a 2-year period were included. All implantations in the first year were performed using the reference technology (Allura Xper), whereas in the second year, the new X-ray technology (AlluraClarity) was used. Radiation exposure, expressed as the dose area product (DAP), was compared between the two time periods to determine the radiation exposure reduction for pacemaker and ICD implantations without cardiac resynchronization therapy (CRT) and with CRT. Procedure duration and contrast volume were used as measures to compare complexity and image quality. The study population consisted of 591 patients who had undergone an implantation using the reference technology, and 594 patients with the new X-ray technology. The two groups did not differ in age, gender, or body mass index. The DAP decreased with 69 % from 16.4 ± 18.5 to 5.2 ± 6.6 Gy cm 2 for the non-CRT implantations (p < 0.001). The DAP decreased with 75 % from 72.1 ± 60.0 to 17.8 ± 17.4 Gy cm 2 for the CRT implantations (p < 0.001). Nevertheless, procedure duration and contrast volume did not differ when using the new technology (p = 0.09 and p = 0.20, respectively). Introduction of new X-ray technology resulted in a radiation exposure reduction of more than 69 % for patients during pacemaker and ICD implantation while image quality was unaffected.

    The human vaginal microbiome is dominated by bacteria from the genus Lactobacillus, which create an acidic environment thought to protect women against sexually transmitted pathogens and opportunistic infections. Strikingly, lactobacilli dominance appears to be unique to humans; while the relative abundance of lactobacilli in the human vagina is typically >70%, in other mammals lactobacilli rarely comprise more than 1% of vaginal microbiota. Several hypotheses have been proposed to explain humans' unique vaginal microbiota, including humans' distinct reproductive physiology, high risk of STDs, and high risk of microbial complications linked to pregnancy and birth. Here, we test these hypotheses using comparative data on vaginal pH and the relative abundance of lactobacilli in 26 mammalian species and 50 studies (N = 21 mammals for pH and 14 mammals for lactobacilli relative abundance). We found that non-human mammals, like humans, exhibit the lowest vaginal pH during the period of highest estrogen. However, the vaginal pH of non-human mammals is never as low as is typical for humans (median vaginal pH in humans = 4.5; range of pH across all 21 non-human mammals = 5.4–7.8). Contrary to disease and obstetric risk hypotheses, we found no significant relationship between vaginal pH or lactobacilli relative abundance and multiple metrics of STD or birth injury risk (P-values ranged from 0.13 to 0.99). Given the lack of evidence for these hypotheses, we discuss two alternative explanations: the common function hypothesis and a novel hypothesis related to the diet of agricultural humans. Specifically, with regard to diet we propose that high levels of starch in human diets have led to increased levels of glycogen in the vaginal tract, which, in turn, promotes the proliferation of lactobacilli. If true, human diet may have paved the way for a novel, protective microbiome in human vaginal tracts. Overall, our results highlight the need for continuing research on non

    Frequently, vaginal fold prolapse is the protrusion of edematous vaginal tissue into and through the opening of the vulva occurring during proestrus and estrus stages of the sexual cycle. True vaginal prolapse may occur near parturition, as the concentration of serum progesterone declines and the concentration of serum oestrogen increases. In the bitch, this type of true vaginal prolapse is a very rare condition. This short communication describes a 5-year-old female, cross-breed dog in moderate condition, weighing 33 kg, with distocia and true vaginal prolapse. Abdominal palpation and transabdominal ultrasonography revealed live and dead foetuses in the uterine horns. One dead and four live fetuses were removed from uterus by cesarean section. The ovariohysterectomy was performed after repositioning the vaginal wall with a combination of traction from within the abdomen and external manipulation through the vulva. Re-occurrence of a vaginal prolapse was not observed and the bitch recovered completely after the surgical therapy. Compared to other vaginal disorders, vaginal prolapse is an uncommon condition in the bitch. In the present case, extreme tenesmus arising from distocia may have predisposed to the vaginal prolapse. The cause of dystocia was probably the disposition of the first foetus. We concluded that the vaginal prolapse was the result of dystocia in the present case.

    To compare the impact of a dinoprostone vaginal insert and intravenous oxytocin in reducing blood loss of women undergoing vaginal or cesarean delivery. This study was conducted among term singleton pregnancies delivered vaginally or by elective cesarean section. In the vaginally delivered cases, active management of the third stage of labor was conducted. During cesarean delivery, 20 IU of intravenous oxytocin was administered. Women, who either delivered via the vaginal or abdominal route, were then randomly allocated to receive 10 mg vaginal dinoprostone insert for 12 hours (group I, n: 100) or intravenous oxytocin (group II, n: 100), respectively. Mean blood loss and need for additional uterotonics and postpartum hemoglobin and hematocrit levels at 24 and 36 hours after delivery did not differ between the two groups. Women allocated to the dinoprostone vaginal insert arm experienced more nausea and vomiting. Dinoprostone vaginal insert was as effective as intravenous oxytocin in the prevention of postpartum blood loss.

    Vaginal symptoms are one of the most common reasons for gynecological consultation. Clinicians have traditionally diagnosed vaginal candidiasis, bacterial vaginosis, and vaginal trichomoniasis using some combination of physical examination, pH, the wet mount, and the whiff test. To evaluate the role of the clinical examination and determine the positive and negative likelihood ratios (LRs) for the diagnosis of vaginal candidiasis, bacterial vaginosis, and vaginal trichomoniasis. Using a structured literature review, we abstracted information on sensitivity and specificity for symptoms, signs, and office laboratory procedures. We chose published (1966 to April 2003) articles that appeared in the MEDLINE database and were indexed under the combined search terms of diagnosis with vaginitis, vaginal discharge, candidiasis, bacterial vaginosis, and trichomoniasis. Included studies of symptomatic premenopausal women seen in primary care settings. Tests were evaluated only if they would provide diagnostic information during the office visit and were compared with an acceptable criterion standard. All 3 authors extracted the data and computed sensitivity and specificity from each article independently. The absence of standard definitions for symptoms and signs made it impossible to combine results across studies. Symptoms alone do not allow clinicians to distinguish confidently between the causes of vaginitis. However, a patient's lack of itching makes candidiasis less likely (range of LRs, 0.18 [95% confidence interval [CI], 0.05-0.70] to 0.79 [95% CI, 0.72-0.87]) and lack of perceived odor makes bacterial vaginosis unlikely (LR, 0.07 [95% CI, 0.01-0.51]). Similarly, physical examination signs are limited in their diagnostic power. The presence of inflammatory signs is associated with candidiasis (range of LRs, 2.1 [95% CI, 1.5-2.8] to 8.4 [95% CI, 2.3-31]). Presence of a "high cheese" odor on examination is predictive of bacterial vaginosis (LR, 3.2 [95% CI, 2

    To report our experience in the management of vaginal extrusion after the tension-free vaginal tape (TVT) procedure for urodynamic stress incontinence. Five patients diagnosed with vaginal extrusion after a TVT procedure performed at our institution were identified. We reviewed the patients' records retrospectively. The interval from TVT placement to diagnosis, presenting symptoms and signs, duration of symptoms, diagnostic test findings, treatment, and postoperative results were recorded. Patients were followed up for at least 12 months. From January 2001 to June 2004, a total of 166 patients underwent the TVT procedure. Of these, 5 patients (3%) were diagnosed with isolated vaginal extrusion 4 to 40 months postoperatively. No cases of urethral or bladder erosion occurred in this series. The symptoms included vaginal discharge, pain, bleeding, and dyspareunia. The eroded margin of the vaginal mucosa was trimmed, mobilized, and closed over the tape with interrupted vertical mattress sutures in a single layer using 2-0 polyglactin 910 to avoid mucosal inversion. All patients remained symptom free without any evidence of defective healing or additional extrusion at a minimal follow-up of 12 months. Primary reclosure of the vaginal mucosa over the TVT tape is an effective first-line treatment option for vaginal extrusion without compromising continence. Patients undergoing the TVT procedure should be adequately counseled about the possibility of this complication and the available treatment options.

    Infectious vaginitis occurs when the normal vaginal flora is disrupted; it may arise when saprophytes overwhelm the host immune response, when pathogenic organisms are introduced into the vagina or when changes in substrate allow an imbalance of microorganisms to develop. Examples of these types of vaginitis include the presence of chronic fungal infection in women with an inadequate cellular immune response to the yeast, the introduction of trichomonads into vaginal epithelium that has a sufficient supply of glycogen, and the alteration in bacterial flora, normally dominated by Lactobacillus spp., and its metabolites that is characteristic of "nonspecific vaginitis". The authors review microbiologic and clinical aspects of the fungal, protozoal and bacterial infections, including the interactions of bacteria thought to produce nonspecific vaginitis, that are now recognized as causing vaginitis. Other causes of vaginitis are also discussed. PMID:3510698

    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.

    Sucrose gel was used to treat bacterial vaginosis in a phase III clinical trial. However, the changes of vaginal flora after treatment were only examined by Nugent score in that clinical trial, While the vaginal microbiota of rhesus macaques is characterized by anaerobic, Gram-negative bacteria, few lactobacilli, and pH levels above 4.6, similar to the microbiota of patients with bacterial vaginosis. This study is aimed to investigate the change of the vaginal microbiota of rehsus macaques after topical use of sucrose gel to reveal more precisely the bacterial population shift after the topical application of sucrose gel. Sixteen rhesus macaques were treated with 0.5 g sucrose gel vaginally and three with 0.5 g of placebo gel. Vaginal swabs were collected daily following treatment. Vaginal pH levels and Nugent scores were recorded. The composition of the vaginal micotbiota was tested by V3∼V4 16S rDNA metagenomic sequencing. Dynamic changes in the Lactobacillus genus were analyzed by qPCR. The vaginal microbiota of rhesus macaques are dominated by anaerobic Gram-negative bacteria, with few lactobacilli and high pH levels above 4.6. After five days' treatment with topical sucrose gel, the component percentage of Lactobacillus in vaginal microbiota increased from 1.31% to 81.59%, while the component percentage of Porphyromonas decreased from 18.60% to 0.43%, Sneathia decreased from 15.09% to 0.89%, Mobiluncus decreased from 8.23% to 0.12%, etc.. The average vaginal pH values of 16 rhesus macaques of the sucrose gel group decreased from 5.4 to 3.89. There were no significant changes in microbiota and vaginal pH observed in the placebo group. Rhesus macaques can be used as animal models of bacterial vaginosis to develop drugs and test treatment efficacy. Furthermore, the topical application of sucrose gel induced the shifting of vaginal flora of rhesus macaques from a BV kind of flora to a lactobacilli-dominating flora. Copyright © 2015 The Authors.

    Our aim was to describe the need for postoperative hospitalization after vaginal surgery for utero-vaginal prolapse with well-defined charts for postoperative care. A prospective, descriptive study. Consecutive women admitted for first-time vaginal surgery for utero-vaginal prolapse at a public university hospital in Copenhagen, Denmark, underwent surgery and postoperative care in a fast track setting from September 15, 1999 to June 15 2000. A multimodal rehabilitation model with emphasis on information, standardized general anesthesia, reduced surgical distress, optimized pain-relief, early oral nutrition and ambulation, minimal use of indwelling catheter and vaginal packing. Postoperative hospital stay, complications, re-admission, success rate, patients' satisfaction and acceptability. Forty-one women with a median age of 69 years (range, 44-88 years) were included. All underwent anterior and/or posterior vaginal repair. Nineteen (46.3%) underwent vaginal hysterectomy, and eight (19.5%) underwent the Manchester procedure. Postoperative hospital stay was median 24 hr. Only three (7.3%) were discharged later than 48 hr. No re-admissions occurred. The most frequent complications were urinary retention exceeding 450 ml, and urinary tract infection (12.2%, and 9.8%, respectively). Short-term success rate was 97.6%. Patients' satisfaction rates were 85.4-95.1%. The median score of acceptability was 10 on a 0-10 points scale. The need for postoperative hospitalization was median 24 hr after vaginal surgery in a fast track setting, independently of the complexity of the procedure performed. Short-term success rate, satisfaction rates, and acceptability were all excellent. Follow up has been established to evaluate long-term success rates and recurrence.

    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.

    Background Bacterial vaginosis (BV) – a syndrome characterised by a shift in vaginal flora – appears to be particularly common in sub-Saharan Africa, but little is known of the pattern of vaginal flora associated with BV in Africa. We conducted a study aimed at determining the prevalence of BV and patterns of BV-associated vaginal micro-flora among women with vaginal discharge syndrome (VDS) in The Gambia, West Africa. Methods We enrolled 227 women with VDS from a large genito-urinary medicine clinic in Fajara, The Gambia. BV was diagnosed by the Nugent's score and Amsel's clinical criteria. Vaginal swabs were collected for T vaginalis and vaginal flora microscopy, and for Lactobacillus spp, aerobic organisms, Candida spp and BV-associated bacteria (Gardnerella vaginalis, anaerobic bacteria, and Mycoplasma spp) cultures; and cervical swabs were collected for N gonorrhoeae culture and C trachomatis PCR. Sera were tested for HIV-1 and HIV-2 antibodies. Sexual health history including details on sexual hygiene were obtained by standardised questionnaire. Results BV prevalence was 47.6% by Nugent's score and 30.8% by Amsel's clinical criteria. Lactobacillus spp were isolated in 37.8% of women, and 70% of the isolates were hydrogen-peroxide (H202)-producing strains. Prevalence of BV-associated bacteria were: G vaginalis 44.4%; Bacteroides 16.7%; Prevotella 15.2%; Peptostretococcus 1.5%; Mobiluncus 0%; other anaerobes 3.1%; and Mycoplasma hominis 21.4%. BV was positively associated with isolation of G vaginalis (odds-ratio [OR] 19.42, 95%CI 7.91 – 47.6) and anaerobes (P = 0.001 [OR] could not be calculated), but not with M hominis. BV was negatively associated with presence of Lactobacillus (OR 0.07, 95%CI 0.03 – 0.15), and H2O2-producing lactobacilli (OR 0.12, 95% CI 0.05 – 0.28). Presence of H2O2-producing lactobacilli was associated with significantly lower prevalence of G vaginalis, anaerobes and C trachomatis. HIV prevalence was 12.8%. Overall, there was

    Recent culture-independent studies have revealed that a healthy vaginal ecosystem harbors a surprisingly complex assemblage of microorganisms. However, the spatial distribution and composition of vaginal microbial populations have not been investigated using molecular methods. Here, we evaluated site-specific microbial composition within the vaginal ecosystem and examined the influence of sampling technique in detection of the vaginal microbiota. 16S rRNA gene clone libraries were prepared from samples obtained from different locations (cervix, fornix, outer vaginal canal) and by different methods (swabbing, scraping, lavaging) from the vaginal tracts of eight clinically healthy, asymptomatic women. The data reveal that the vaginal microbiota is not homogenous throughout the vaginal tract but differs significantly within an individual with regard to anatomical site and sampling method used. Thus, this study illuminates the complex structure of the vaginal ecosystem and calls for the consideration of microenvironments when sampling vaginal microbiota as a clinical predictor of vaginal health.

    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. 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. 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. Sustained use of the NES/EE CVR did not increase the risk of vaginal infection and was not disruptive to the vaginal ecosystem. Clinical

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

    Vaginal calculus is a rare disorder which has been reported in association with urethral diverticulum, urogenital sinus anomaly, bladder exstrophy and the tension-free vaginal tape (TVT) procedure. We report a 42-year-old woman who presented with persistent, intractable urinary tract infection (UTI) following a TVT procedure. Cystoscopy demonstrated an eroded tape with the formation of a bladder calculus, and the patient underwent laser cystolithotripsy and cystoscopic resection of the tape. Following this procedure, her UTI completely resolved and she remained asymptomatic for several years. Seven years later she presented with a solid vaginal mass. Pelvic examination followed by transvaginal ultrasonography and magnetic resonance imaging demonstrated a large vaginal calculus located at the lower third of the anterior vaginal wall adjacent to the bladder neck. This video presents the transvaginal excision and removal of the vaginal calculus.

    Vaginal calculi are extremely rare and are most commonly encountered in the setting of an urethrovaginal or vesicovaginal fistula. We present a case of a 72-year-old woman with mixed urinary incontinence and vaginal mesh exposure incidentally found to have a large vaginal calculus. We removed the calculus surgically and analyzed the components. Results demonstrated the presence of ammonium-magnesium phosphate hexahydrate and carbonate apatite.

    Radiation therapy's (RT's) effects on cardiac implantable electronic devices (CIEDs) such as implantable cardioverter-defibrillators (ICDs) and pacemakers (PMs) are not well established, leading to device removal or relocation in preparation for RT. To determine the effect of scattered RT on CIED performance. We analyzed 69 patients--50 (72%) with PMs and 19 (28%) with ICDs--receiving RT at the University of Michigan. Collected data included device model, anatomic location, and treatment beam energies, treatment type, and estimated dose to the device. Patients were treated with either high-energy (16-MV) and/or low-energy (6 MV) photon beams with or without electron beams (6-16 MeV). The devices were interrogated with pre- and post-RT and/or weekly with either in-treatment or home interrogation, depending on the patient's dependence on the device and the estimated or measured delivered dose. Outcomes analyzed were inappropriate ICD therapies, device malfunctions, or device-related clinical events. The PMs were exposed to 84.4 ± 99.7 cGy of radiation, and the ICDs were exposed to 92.1 ± 72.6 cGy of radiation. Two patients with ICDs experienced a partial reset of the ICD with the loss of historic diagnostic data after receiving 123 and 4 cGy, respectively. No device malfunction or premature battery depletion was observed at 6-month follow-up from RT completion. CIED malfunction due to indirect RT exposure is uncommon. Regular in-treatment or home interrogation should be done to detect and treat these events and to ensure that diagnostic data are preserved. Copyright © 2012 Elsevier Inc. All rights reserved.

Members of the North American Society for Pediatric and Adolescent Gynecology. How providers learn about vaginal dilator training, common techniques, and methods used for patient training, assessment of patient readiness, common patient complaints, issues leading to early discontinuation. There were a total of 55 completed survey responses of which 31 respondents (56%) had been in practice for more than 10 years. Forty-nine were gynecologists (89%), 20 had completed a fellowship in pediatric and adolescent gynecology (36%), and 6 were reproductive endocrinologists (11%). Thirty-one respondents had first learned about vaginal dilator training through lectures (56%) whereas only 9 through mentorship and fellowship (16%). According to respondents, the most common issue leading to early discontinuation was lack of patient motivation and readiness (n = 42; 76%). The most common complication was pain or discomfort (n = 45; 82%). More than half of respondents determined dilator therapy was successful when patients reported comfortable sexual intercourse (n = 30; 55%) and 65% (n = 35) did not delineate any restrictions to initiation of sexual intercourse. Most respondents (87%) requested further vaginal dilator training at either a clinical meeting (n = 26; 47%) or with a training video (n = 22; 40%). Our study in an experienced cohort of pediatric gynecology providers highlights the need for further research and training on vaginal dilation education.

    This study examined the impact of 935MHz phone-simulating electromagnetic radiation on embryo implantation of pregnant mice. Each 7-week-old Kunming (KM) female white mouse was set up with a KM male mouse in a single cage for mating overnight after induction of ovulation. In the first three days of pregnancy, the pregnant mice was exposed to electromagnetic radiation at low-intensity (150 μW/cm(2), ranging from 130 to 200 μW/cm(2), for 2- or 4-h exposure every day), mid-intensity (570 μW/cm(2), ranging from 400 to 700 μW/cm(2), for 2- or 4-h exposure every day) or high-intensity (1400 μW/cm(2), ranging from 1200 to 1500 μW/cm(2), for 2- or 4-h exposure every day), respectively. On the day 4 after gestation (known as the window of murine embryo implantation), the endometrium was collected and the suspension of endometrial glandular cells was made. Laser scanning microscopy was employed to detect the mitochondrial membrane potential and intracellular calcium ion concentration. In high-intensity, 2- and 4-h groups, mitochondrial membrane potential of endometrial glandular cells was significantly lower than that in the normal control group (P<0.05). The calcium ion concentration was increased in low-intensity 2-h group but decreased in high-intensity 4-h group as compared with the normal control group (P<0.05). However, no significant difference was found in mitochondrial membrane potential of endometrial glandular cells between low- or mid-intensity groups and the normal control group, indicating stronger intensity of the electromagnetic radiation and longer length of the radiation are required to inflict a remarkable functional and structural damage to mitochondrial membrane. Our data demonstrated that electromagnetic radiation with a 935-MHz phone for 4 h conspicuously decreased mitochondrial membrane potential and lowered the calcium ion concentration of endometrial glandular cells. It is suggested that high-intensity electromagnetic radiation is very likely

    Implanted markers as target surrogates have been widely used for treatment verification, as they provide safe and reliable monitoring of the inter- and intra-fractional target motion. The rapid advancement of technology requires a critical review and recommendation for the usage of implanted surrogates in current field. The symposium, also reporting an update of AAPM TG 199 - Implanted Target Surrogates for Radiation Treatment Verification, will be focusing on all clinical aspects of using the implanted target surrogates for treatment verification and related issues. A wide variety of markers available in the market will be first reviewed, including radiopaque markers, MRImore » compatible makers, non-migrating coils, surgical clips and electromagnetic transponders etc. The pros and cons of each kind will be discussed. The clinical applications of implanted surrogates will be presented based on different anatomical sites. For the lung, we will discuss gated treatments and 2D or 3D real-time fiducial tracking techniques. For the prostate, we will be focusing on 2D-3D, 3D-3D matching and electromagnetic transponder based localization techniques. For the liver, we will review techniques when patients are under gating, shallow or free breathing condition. We will review techniques when treating challenging breast cancer as deformation may occur. Finally, we will summarize potential issues related to the usage of implanted target surrogates with TG 199 recommendations. A review of fiducial migration and fiducial derived target rotation in different disease sites will be provided. The issue of target deformation, especially near the diaphragm, and related suggestions will be also presented and discussed.

    Iwase, A.; Rehn, L. E.; Baldo, P. M.; Funk, L.

    Effects of He implantation on radiation induced segregation (RIS) in Cu-Au and Ni-Si alloys were investigated using in situ Rutherford backscattering spectrometry during simultaneous irradiation with 1.5-MeV He and low-energy (100 or 400-keV) He ions at elevated temperatures. RIS during single He ion irradiation, and the effects of pre-implantation with low-energy He ions, were also studied. RIS near the specimen surface, which was pronounced during 1.5-MeV He single-ion irradiation, was strongly reduced under low-energy He single-ion irradiation, and during simultaneous irradiation with 1.5-MeV He and low-energy He ions. A similar RIS reduction was also observed in the specimens pre-implanted with low-energy He ions. The experimental results indicate that the accumulated He atoms cause the formation of small bubbles, which provide additional recombination sites for freely migrating defects.

    Our aim was to compare histological and biomechanical effects of polypropylene (PP) mesh and porcine-derived, cross-linked urinary bladder matrix (cUBM) graft materials using a rabbit vaginal and abdominal model. Forty rabbits were implanted with PP mesh (n = 20) or cUBM (n = 20) in the vagina and abdomen. Two grafts (PP or cUBM) of the same type were placed into each site, so each rabbit had four grafts. Grafts were harvested 12 weeks later and processed for histologic analysis and biomechanical testing. There were high rates of two types of grafts missing in the vagina. Vaginal PP was associated with erosion reaction (67%), whereas abdominal PP and cUBM showed no sign of erosion. All patches adhered to rectus abdominis or vaginal mucosa and shrank to varying degrees, especially for PP grafts. Compared with vaginal PP, vaginal cUBM induced milder chronic inflammation response, had lower scores (P = 0.000) for inflammation response, and showed higher scores for neovascularization (P = 0.000) and fibroblastic proliferation (P = 0.002). In the abdomen, both histopathological parameters were insignificantly different (P > 0.05) between cUBM and PP. The mechanical properties of UBM did not deteriorate following implantation, whereas the ultimate tensile strength and elastic modulus of vaginal PP increased. PP had higher scores for tensile and break strength than did cUBM (P < 0.05). The cUBM has good biocompatibility, high ability to integrate with the vagina, and maintains mechanical properties in vivo. It may be a promising material for pelvic floor reconstruction.

    Vaginitis is one of the most common complaints of women in the United States today. About 90% of patients with this problem suffer from infection of the vagina caused by Candida, Gardnerella, or Trichomonas. The diagnosis and effective treatment of these common infections depend on accurate identification of the entity, effective specific therapy, and restoration of the normal ecosystem of the vagina. At the same time women should be made aware that not all discharge means infection and that any attempts at self-treatment may only worsen their condition. Proper hygiene habits, dietary control, and management of stress are all helpful factors in the control of recurrent vaginal infections.

    In order to evaluate an effective administration method of essential oils for vaginal candidiasis, efficacy of vaginal application of essential oils against murine experimental candidiasis was investigated. The effect on vaginal inflammation and Candida growth form was also studied. Vaginal candidiasis was established by intravaginal infection of C. albicans to estradiol-treated mice. These mice intravaginally received essential oils such as geranium and tea tree singly or in combination with vaginal washing. Vaginal administration of clotrimazole significantly decreased the number of viable C. albicans cells in the vaginal cavity by itself. In contrast, these essential oils did not lower the cell number. When application of geranium oil or geraniol was combined with vaginal washing, the cell number was decreased significantly. The myeloperoxidase activity assay exhibited the possibility that essential oils worked not only to reduce the viable cell number of C. albicans, but also to improve vaginal inflammation. The smear of vaginal washing suspension suggested that more yeast-form cells appeared in vaginal smears of these oil-treated mice than in control mice. In vitro study showed that a very low concentration (25 microg/ml) of geranium oil and geraniol inhibited mycelial growth, but not yeast growth. Based on these findings, it is estimated that vaginal application of geranium oil or its main component, geraniol, suppressed Candida cell growth in the vagina and its local inflammation when combined with vaginal washing.

Open-label, prospective pilot study conducted in asymptomatic women in daily practice. Cervical epithelization was evaluated by colposcopy using an ectopy epithelization score (from 5: no ectopy to 1: severe ectopy and bleeding), vaginal microbiota using the VaginaStatus-Diagnostic test (Instiüt für Mikroökologie, Herborn, Germany) and further rated by the investigator using a 5-point Liker scale (from 5: normal to 1: very severe deterioration in which all evaluated species were altered), and vaginal health using the Vaginal Health Index. In 21 women, a positive effect to improve epithelization of the cervical mucosa, with a mean score of 4.42 at the final visit as compared to 3.09 at baseline (P < 0.0001) (43% improvement). In 10 women, there was a trend of improving of vaginal microbiota status, with a mean score of 4.0 at the final visit vs. 3.3 at baseline (P = NS) (21.2% improvement). In 11 women, the Vaginal Health Index increased from 19.0 at baseline to 22.3 at the final visit (P = 0.007). The concentration of Lactobacillus spp. increased 54.5% of women and pH decreased from 4.32 to 4.09.

    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.

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. © 2013 The Authors.

    To demonstrate the effectiveness of medical-grade stainless steel Water Works Douching Device for treating abnormal vaginal odor in comparison with a commercially available over-the-counter plastic douching device. In a multicenter study, 140 women with perceived vaginal odor with no vaginal infection were randomized to either Water Works or control group in a 1:1 ratio and were douched daily for 4 weeks. A visual analog scale (VAS) was used to assess the intensity of vaginal odor. Primary outcome included subject assessment of odor improvement and Nugent Gram stain score of vaginal secretions. Secondary outcome compared the efficacy and safety of Water Works with control douching device. Each patient underwent baseline, week 2, and week 4 visits. The final analytic sample consisted of 96 women. Success score at 4 weeks was 78% for the Water Works group and 38.5% for the control group. Mean VAS was significantly reduced, and Nugent and Lactobacillus scores were maintained in both groups. In the Water Works group, VAS was reduced from 7.3 ± 0.3 to 1.8 ± 0.6 (p < .001) after 4 weeks. In the control group, baseline versus 4 weeks VAS was 7.2 ± 0.3 and 3.4 ± 0.8 (p < .003). Women reported significant reduction of vaginal odor after douching with water for 4 weeks without any alteration of vaginal flora. The Water Works Douching Device was superior to over- the-counter device in reducing vaginal odor.

    Surgical site infections remain a common cause of morbidity following gynaecological surgery. The widespread implementation of antibiotic prophylaxis prior to surgery, as well as cognizance of modifiable risk factors for postoperative infection, has led to a significant reduction in postoperative infection rates. However, in low resource settings where sepsis and infections are common, surgical site infections following vaginal hysterectomy are sometimes encountered. It is a challenge to treat these infections with minimal intervention avoiding repeat surgery. We report here a unique situation following vaginal hysterectomy and then laparotomy; where a pelvic abscess communicated with the vesicovaginal space and drained through an opening into the anterior vaginal wall. An innovative technique was used to drain this anterior vaginal wall abscess connecting to pelvic cavity using a 40 cm long disposable urinary catheter (made of polyvinyl chloride), which was inserted into the vaginal opening under ultrasound guidance. 2016 BMJ Publishing Group Ltd.

    The vaginal immune system (VIS) is the first defense against antigens recognized as foreign. Substances capable of locally activating the VIS could be a valid strategy to treat vulvo-vaginal infections (VVI), caused by changes in the vaginal ecosystem, such as bacterial vaginosis (BV), vulvo-vaginal candidiasis (CA), and mixed vaginitis (MV). Bacterial lysates, obtained by crushing bacterial cultures, exert immuno-modulatory activities. The parietal fraction from Propionibacterium acnes is a patent of Depofarma (MoglianoVeneto, Italy). The preparation that associates such fraction to hyaluronic acid and polycarbophil is a registered trademark, commercially available in Italy as vaginal gel, Immunovag ® . The study aimed to evaluate whether a 5-day-treatment with Immunovag ® improves the symptoms and signs of VVI, in 60 women with Gardnerella vaginalis (GV), 154 with CA, 95 with MV, diagnosed with vulvar vaginal swab (VVS), and in 283 with BV, diagnosed with the Amsel criteria. At the end of the treatment (visit 2), the symptoms and signs of VVI disappeared in a significant number of subjects (χ 2 p < .02 vs pre-treatment) in all VVI groups, and their intensity was significantly (p < .0002) reduced in the subjects in which they were still present. Immunovag ® represents a valid treatment of VVI induced by changes in the vaginal ecosystem.

    Boron doped silicon n+p solar cells were counterdoped with lithium by ion implantation and the resuitant n+p cells irradiated by 1 MeV electrons. The function of fluence and a Deep Level Transient Spectroscopy (DLTS) was studied to correlate defect behavior with cell performance. It was found that the lithium counterdoped cells exhibited significantly increased radiation resistance when compared to boron doped control cells. It is concluded that the annealing behavior is controlled by dissociation and recombination of defects. The DLTS studies show that counterdoping with lithium eliminates at least three deep level defects and results in three new defects. It is speculated that the increased radiation resistance of the counterdoped cells is due primarily to the interaction of lithium with oxygen, single vacanies and divacancies and that the lithium-oxygen interaction is the most effective in contributing to the increased radiation resistance.

    The medical community is advocating for progressive improvement in the design of implantable cardioverter-defibrillators and implantable pacemakers to accommodate elevations in dose limitation criteria. With advancement already made for magnetic resonance imaging compatibility in some, a greater need is present to inform the radiation oncologist and medical physicist regarding treatment planning beam profile changes when such devices are in the field of a therapeutic radiation beam. Treatment plan modeling was conducted to simulate effects induced by Medtronic, Inc.-manufactured devices on therapeutic radiation beams. As a continuation of grant-supported research, we show that radial and transverse open beam profiles of amore » medical accelerator were altered when compared with profiles resulting when implantable pacemakers and cardioverter-defibrillators are placed directly in the beam. Results are markedly different between the 2 devices in the axial plane and the sagittal planes. Vast differences are also presented for the therapeutic beams at 6-MV and 18-MV x-ray energies. Maximum changes in percentage depth dose are observed for the implantable cardioverter-defibrillator as 9.3% at 6 MV and 10.1% at 18 MV, with worst distance to agreement of isodose lines at 2.3 cm and 1.3 cm, respectively. For the implantable pacemaker, the maximum changes in percentage depth dose were observed as 10.7% at 6 MV and 6.9% at 18 MV, with worst distance to agreement of isodose lines at 2.5 cm and 1.9 cm, respectively. No differences were discernible for the defibrillation leads and the pacing lead.« less

    Although human papillomavirus (HPV) is the most common sexually transmitted infection, there are very scant data about the influence of this virus on the in vitro fertilization outcome. To assess the presence of HPV in the cervico-vaginal fluid in relationship to the in vitro fertilization (IVF) outcome and to the concentration of selected cytokines, known to affect embryo implantation and gestation: granulocyte-macrophage colony stimulating factor (GM-CSF) and granulocyte colony stimulating factor (G-CSF). Cervico-vaginal samples were collected on the day of oocyte pick-up from 82 women. Vaginas were flushed with 50 mL of sterile water and 3 mL of fluid was collected. Twelve women (15%) were positive for HPV. Interestingly, among HPV(+) women live birth rate was about half of the rate in HPV(-) women, although the differences were not statistically significant due to the low number of cases. Cervico-vaginal samples of a sub-group of 29 (8 HPV(+) and 21 HPV(-)) women were analyzed for GM-CSF and G-CSF by ELISA. GM-CSF but not G-CSF was significantly lower in the cervico-vaginal fluid of HPV(+) than in HPV(-) women. Since GM-CSF plays an important role during pregnancy, the reduced levels of GM-CSF in the cervico-vaginal fluid of HPV(+) women might contribute to explain the reduced live birth rate observed in HPV(+) women.

  2. Action against contraceptive implant threatened.

    Norplant provides contraception over a five-year period through the gradual subcutaneous release of the progestogen levonorgestrel. It has been on the US market since 1991 and available in Great Britain since 1993. Already the subject of group legal actions in several US states, Norplant may soon be the target of lawyers in Britain for litigation. The lawyers allege that insertion of the implant under the skin of the upper arm by untrained doctors has led to painful and difficult removals and left women with scarred arms. Moreover, insufficient warning has been given about possible side effects such as mood swings and continuous vaginal bleeding. Hoechst Roussel, marketer of the implant in Britain, however, argues that only doctors trained in Norplant insertion and removal should attempt either procedure. Removal will be problematic only if preceded by a problem insertion. Hoechst Roussel recently advised gynecologists, in writing, not to attempt to extract the implant unless they are trained in the removal technique. By British law, the application of a drug product once approved for general release to general practitioners and family planning doctors cannot be restricted by a pharmaceutical company.

    The diagnostic criteria and treatment of aerobic vaginitis--AV--have been summarized in this review. 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.

    The aim of this study was to explore whether an in-house dosimetry protocol and optimisation method are able to produce a homogeneous dose distribution in the target volume, and how often optimisation is required in vaginal cuff brachytherapy. Treatment planning was carried out for 109 fractions in 33 patients who underwent high dose rate iridium-192 (Ir(192)) brachytherapy using Fletcher ovoids. Dose prescription and normalisation were performed to catheter-oriented lateral dose points (dps) within a range of 90-110% of the prescribed dose. The in-house vaginal apex point (Vk), alternative vaginal apex point (Vk'), International Commission on Radiation Units and Measurements (ICRU) rectal point (Rg) and bladder point (Bl) doses were calculated. Time-position optimisations were made considering dps, Vk and Rg doses. Keeping the Vk dose higher than 95% and the Rg dose less than 85% of the prescribed dose was intended. Target dose homogeneity, optimisation frequency and the relationship between prescribed dose, Vk, Vk', Rg and ovoid diameter were investigated. The mean target dose was 99+/-7.4% of the prescription dose. Optimisation was required in 92 out of 109 (83%) fractions. Ovoid diameter had a significant effect on Rg (p = 0.002), Vk (p = 0.018), Vk' (p = 0.034), minimum dps (p = 0.021) and maximum dps (p<0.001). Rg, Vk and Vk' doses with 2.5 cm diameter ovoids were significantly higher than with 2 cm and 1.5 cm ovoids. Catheter-oriented dose point normalisation provided a homogeneous dose distribution with a 99+/-7.4% mean dose within the target volume, requiring time-position optimisation.

    In H&N cancer patients, the development of oral mucositis is related closely to the radiation dose to the oral cavity. It is generally presumed that the existence of metallic dental implants makes it worse due to the scattering effect of the metal. This study investigates the effects of the dental implants on radiation doses to PTV, tongue mucosa, and other structures for IMRT H&N cancer patients by Monte Carlo (MC) dose calculations. Two H&N cancer patients who have dental implant and are treated by IMRT technique are selected for the purpose. The BEAMnrc/DOSXYZnrc MC codes are employed for the CT-image based dose calculations. The radiation sources are the validated Varian phase-space files for 6MV linac beams. The CT image artifacts caused by the dental fillings are replaced by tissue material. Two sets of MC calculations for each patient are performed at a calculation statistics of 1%: one treats all dental implants as bones, the other substitutes the implants by metal of either titanium or gold with correct density. Doses in PTV and various tissue structures are compared for the two scenarios. With titanium implant, there is no significant difference in doses to PTV and tongue mucosa from that when treating implant as bone. With gold implant, the mean dose to PTV is slightly lowered by 1%; the mean dose to tongue mucosa is reduced by less than 0.5%, although the maximum dose is increased by 5%. The scattering dose from titanium implants is not of concern for H&N patients irradiated by 6MV IMRT beams. For gold implants, the scattering dose to tongue mucosa is not as severe as presumed; and the dose to PTV could be slightly compromised due to the attenuation effect of the metal.

    Implanted markers as target surrogates have been widely used for treatment verification, as they provide safe and reliable monitoring of the inter- and intra-fractional target motion. The rapid advancement of technology requires a critical review and recommendation for the usage of implanted surrogates in current field. The symposium, also reporting an update of AAPM TG 199 - Implanted Target Surrogates for Radiation Treatment Verification, will be focusing on all clinical aspects of using the implanted target surrogates for treatment verification and related issues. A wide variety of markers available in the market will be first reviewed, including radiopaque markers, MRImore » compatible makers, non-migrating coils, surgical clips and electromagnetic transponders etc. The pros and cons of each kind will be discussed. The clinical applications of implanted surrogates will be presented based on different anatomical sites. For the lung, we will discuss gated treatments and 2D or 3D real-time fiducial tracking techniques. For the prostate, we will be focusing on 2D-3D, 3D-3D matching and electromagnetic transponder based localization techniques. For the liver, we will review techniques when patients are under gating, shallow or free breathing condition. We will review techniques when treating challenging breast cancer as deformation may occur. Finally, we will summarize potential issues related to the usage of implanted target surrogates with TG 199 recommendations. A review of fiducial migration and fiducial derived target rotation in different disease sites will be provided. The issue of target deformation, especially near the diaphragm, and related suggestions will be also presented and discussed.

    Childhood vaginal discharge remains a frequent reason for referral from primary to secondary care. The Pediatric and Adolescent Gynecology (PAG) service at Kettering General Hospital was established in 1993 and provides a specialized service that meets the needs of children with gynaecological conditions. To investigate recurrent vaginal discharge noting symptomatology, defining pathogens, common and rarer causes, exploring management regimes, and any changes in practice over time. Retrospective review spanning 15 years identifying prepubertal children attending the outpatient PAG clinic with recurrent vaginal discharge. We reviewed the medical notes individually. 110 patients were identified; 85% were referred from primary care. The age distribution was bimodal at four and eight years. Thirty-five percent of our patients were discharged after the initial consultation. The commonest cause of discharge was vulvovaginitis (82%). Other important causes included suspected sexual abuse (5%), foreign body (3%), labial adhesions (3%), vaginal agenesis (2%). 35% of patients were admitted for vaginoscopy. Vaginal discharge is the most common gynecological symptom in prepubertal girls and can cause repeated clinical episodes. Vulvovaginitis is the most common cause and often responds to simple hygiene measures. Awareness of the less common causes of vaginal discharge is essential.

    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-1β (IL-1β) 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-1β and IL-18 production by vaginal epithelial cells, and blockade of the IL-1β 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

    Vaginal washings of 22 patients with vaginitis, 11 with vaginosis, and 12 healthy subjects were investigated quantitatively and qualitatively for aerobic and anaerobic bacteria and yeasts. Gardnerella vaginalis was recovered from 9 of the vaginitis patients, 7 of the vaginosis patients, and 4 of the asymptomatic subjects. Obligate anaerobes were found in 11 of the vaginitis patients, 4 of the vaginosis patients, and none of the control subjects. Bacteroides bivius was the anaerobe most frequently isolated from symptomatic subjects. Anaerobic vibrios were recovered twice from symptomatic subjects. The counts for Gardnerella vaginalis and anaerobes when present were generally very high. The most frequent aerobes were beta-hemolytic streptococci (group B) and staphylococci.

    To assess the association of vaginal pH ≥ 5 in the absence of vaginal infection with systemic inflammation and adverse pregnancy outcome. Four-hundred sixty pregnant women completed the study, upon enrollment Vaginal pH was measured for all women, maternal and umbilical sera were obtained for determining C-reactive protein (CRP) and uric acid levels. Umbilical blood was tested for gas parameters, 1 and 5 min Apgar scores, the need for neonatal resuscitation and neonatal intensive care unit (NICU) admission were recorded. Elevated vaginal pH was significantly associated with preterm birth (odds ratio (OR), 2.23; 95% confidence interval (CI), 1.04-4.76), emergency cesarean section (OR 2.57; 95% CI 1.32-5), neonatal resuscitation in the delivery room (OR 2.85; 95% CI 1.1-7.38), elevated cord base deficit (OR 8.01; 95% CI 1.61-39.81), low cord bicarbonate (OR 4.16, 95% CI 1.33-12.92) and NICU admission (OR 2.02; 95% CI 1.12-3.66). Increased vaginal pH was also significantly associated with maternal leukocytosis, hyperuricemia and elevated CRP levels in maternal and umbilical sera. Elevated vaginal pH in the absence of current vaginal infection still constitutes a risk for adverse pregnancy outcome which is mediated by systemic inflammatory response.

    The paper describes the operation of a patented wireless RF telemetry system, consisting of a bio-MEMS implantable sensor and an external hand held unit, operating over the frequency range of few hundreds of MHz. A MEMS capacitive pressure sensor integrated with a miniature inductor/antenna together constitute the implantable sensor. Signal processing circuits collocated with a printed loop antenna together form the hand held unit, capable of inductively powering and also receiving the telemetry signals from the sensor. The paper in addition, demonstrates a technique to enhance the quality factor and inductance of the inductor in the presence of a lower ground plane and also presents the radiation characteristics of the loop antenna.

  16. Vaginal eroticism: a replication study.

    1985-12-01

    Vaginal eroticism was investigated in a group of 27 coitally experienced volunteers by means of systematic digital stimulation of both vaginal walls. Erogenous zones were found in all subjects, mainly located on the upper anterior wall and the lower posterior one. An orgasmic response was elicited by stimulation of these zones in 89% of the subjects. This study supports previous findings regarding vaginal eroticism. It does not support the existence of the discrete anatomical structure called the Grafenberg spot. It supports the contention that there are two distinct types of female orgasm, vaginally evoked and clitorally evoked. It also supports the finding that some women expel a fluid through the urethra at the time of orgasm. In this particular case the fluid was chemically indistinguishable from urine.

    To evaluate the incidence of, indications for, and outcome of operative vaginal deliveries compared with spontaneous vaginal deliveries in southeast Nigeria. A retrospective cohort study was conducted involving cases of operative vaginal delivery performed at Ebonyi State University Teaching Hospital over a 10-year period. Data on the procedures were abstracted from the operation notes of the medical records of parturients. An incidence of 4.7% (n = 461) was recorded. The most common indications for vacuum and forceps delivery were prolonged second stage of labor (44.9%) and poor maternal effort (27.8%). The only indication for destructive operation was intrauterine fetal death (3.7%). The risk ratio (RR) for hemorrhage/vulvar hematoma was 1.14 (95% confidence interval [CI], 0.53-2.48) for vacuum-assisted delivery and 5.49 (95% CI, 0.82-36.64) for forceps delivery. The RR for genital laceration was 1.21 (95% CI, 0.44-3.30) for vacuum-assisted delivery and 9.41 (95% CI, 1.33-66.65) for forceps delivery. The risk of fetal scalp bruises and caput succedaneum was higher for operative vaginal delivery than for spontaneous vaginal delivery, with no significant difference in maternal morbidity. The perinatal mortality rate was 0.9 per 1000 live births. Operative vaginal delivery by experienced healthcare providers is associated with good obstetric outcomes with minimal risk.

    Excessive radiation exposure may lead to edema of the spinal cord and deterioration of the nervous system. Magnetic resonance imaging can be used to judge and assess the extent of edema and to evaluate pathological changes and thus may be used for the evaluation of spinal cord injuries caused by radiation therapy. Radioactive 125I seeds to irradiate 90% of the spinal cord tissue at doses of 40–100 Gy (D90) were implanted in rabbits at T10 to induce radiation injury, and we evaluated their safety for use in the spinal cord. Diffusion tensor imaging showed that with increased D90, the apparent diffusion coefficient and fractional anisotropy values were increased. Moreover, pathological damage of neurons and microvessels in the gray matter and white matter was aggravated. At 2 months after implantation, obvious pathological injury was visible in the spinal cords of each group. Magnetic resonance diffusion tensor imaging revealed the radiation injury to the spinal cord, and we quantified the degree of spinal cord injury through apparent diffusion coefficient and fractional anisotropy.

    Scanning white light interferometry and Raman spectroscopy were used to investigate the mechanical stresses and structural changes in ion-implanted natural diamonds with different impurity content. The uniform distribution of radiation defects in implanted area was obtained by the regime of multiple-energy implantation of keV He+ ions. A modification of Bosia's et al. (Nucl. Instrum. Meth. B 268 (2010) 2991) method for determining the internal stresses and the density variation in an ion-implanted diamond layer was proposed that suggests measuring, in addition to the surface swelling of a diamond plate, the radius of curvature of the plate. It is shown that, under multiple-energy implantation of He+, mechanical stresses in the implanted layer may be as high as 12 GPa. It is shown that radiation damage reaches saturation for the implantation fluence characteristic of amorphization of diamond but is appreciably lower than the graphitization threshold.

    Objective Define the impact of prolapse mesh on the biomechanical properties of the vagina by comparing the prototype Gynemesh PS (Ethicon, Somerville, NJ) to 2 new generation lower stiffness meshes, SmartMesh (Coloplast, Minneapolis, MN) and UltraPro (Ethicon). Design A study employing a non-human primate model Setting University of Pittsburgh Population 45 parous rhesus macaques Methods Meshes were implanted via sacrocolpexy after hysterectomy and compared to Sham. Because its stiffness is highly directional UltraPro was implanted in two directions: UltraPro Perpendicular (less stiff) and UltraPro Parallel (more stiff), with the indicated direction referring to the blue orientation lines. The mesh-vaginal complex (MVC) was excised en toto after 3 months. Main Outcome Measures Active mechanical properties were quantified as contractile force generated in the presence of 120 mM KCl. Passive mechanical properties (a tissues ability to resist an applied force) were measured using a multi-axial protocol. Results Vaginal contractility decreased 80% following implantation with the Gynemesh PS (p=0.001), 48% after SmartMesh (p=0.001), 68% after UltraPro parallel (p=0.001) and was highly variable after UltraPro perpendicular (p =0.16). The tissue contribution to the passive mechanical behavior of the MVC was drastically reduced for Gynemesh PS (p=0.003) but not SmartMesh (p=0.9) or UltraPro independent of the direction of implantation (p=0.68 and p=0.66, respectively). Conclusions Deterioration of the mechanical properties of the vagina was highest following implantation with the stiffest mesh, Gynemesh PS. Such a decrease associated with implantation of a device of increased stiffness is consistent with findings from other systems employing prostheses for support. PMID:23240801

    Desquamative inflammatory vaginitis is an uncommon cause of an intractable vaginitis often accompanied by serious dyspareunia, which can occur at any stage of reproductive life and after the menopause. The cytological changes are identical with those seen in atrophic vaginitis yet the disorder often occurs in the presence of apparently normal ovarian function. Vaginal synechiae and stenosis develop in an appreciable number of patients. Treatment is unsatisfactory though there is some response to either local or systemic steroid therapy. The literature is reviewed and the association of some cases with lichen planus of the mouth and genitals discussed. Its causation and natural history remain largely unknown and there is as yet, insufficient evidence to regard it as a single entity. It is likely that the incidence of the disorder is underestimated.

    A woman's vaginal pH has many implications on her health and it can be a useful tool in disease diagnosis and prevention. For that reason, the further examination of the relationship between the human vaginal pH and microbiota is imperative. In the past several decades, much has been learned about the physiological mechanisms modulating the vaginal pH, and exogenous/genetic factors that may influence it. A unified, coherent understanding of these concepts is presented to comprehend their interrelationships and their cumulative effect on a woman's health. In this review, we explore research on vaginal pH and microbiota throughout a woman's life, vaginal intermediate cell anaerobic metabolism and net proton secretion by the vaginal epithelial, and the way these factors interact to acidify the vaginal pH. This review provides foundational information about what a microbiota is and its relationship with human physiology and vaginal pH. We then evaluate the influence of physiological mechanisms, demographic factors, and propose ideas for the mechanisms behind their action on the vaginal pH.

    To evaluate interrelationships between bacterial vaginosis (BV), vaginal yeast, vaginal practices (cleansing and drying/tightening), mucosal inflammation, and HIV acquisition. A multicenter, prospective, observational cohort study was conducted, enrolling 4531 HIV-negative women aged 18 to 35 years attending family planning clinics in Zimbabwe and Uganda. Participants were tested for HIV and reproductive tract infections and were interviewed about vaginal practices every 3 months for 15 to 24 months. BV was measured by Gram stain Nugent scoring, vaginal yeast by wet mount, and mucosal inflammation by white blood cells on Gram stain. HIV incidence was 4.12 and 1.53 per 100 woman-years of follow-up in Zimbabwe and Uganda, respectively (a total of 213 incident infections). Women with BV or vaginal yeast were more likely to acquire HIV, especially if the condition was present at the same visit as the new HIV infection and the visit preceding it (hazard ratio [HR] = 2.50, 95% confidence interval [CI]: 1.68 to 3.72 and HR = 2.97, 95% CI: 1.67 to 5.28 for BV and yeast, respectively). These relationships did not seem to be mediated by mucosal inflammation. Vaginal drying/tightening was associated with HIV acquisition in univariate (HR = 1.49, 95% CI: 1.03 to 2.15) but not multivariate models. Vaginal cleansing was not associated with HIV acquisition. BV and yeast may contribute more to the HIV epidemic than previously thought.

    To investigate clinical characteristics of aerobic vaginitis (AV) and its mixed infections for diagnosis efficiently. From April 2008 to December 2008, 516 patients with vaginitis treated in Tianjin Medical University General Hospital were enrolled in this study. AV, bacterial vaginosis (BV), vulvovaginal candidiasis (VVC), trichomonal vaginitis (TV), and cytolytic vaginosis (CV) were diagnosed based on symptoms, sign and vaginal discharge examination. Among 516 cases, AV cases were found in 14.7% (76/516), and AV was common vaginal infection. AV mixed infections was diagnosed in 58% (44/76), including mixed with BV (45%, 20/44), mixed with VVC (30%, 13/44), and mixed with TV (25%, 11/44). Those common symptom of AV were yellow vaginal discharge (63%, 20/32), more vaginal discharge (44%, 14/32). Vaginal pH value was usually more than 4.5 (84%, 27/32). Vaginal cleanliness mainly was grade III - IV (88%, 28/32). Six cases with enterococcus faecium and 4 cases with streptococci were frequently isolated. The symptom and sign of mixed AV infection was atypical. Aerobic vaginitis is a common lower vaginal infection and easily mixed with other pathogens, especially with BV, VVC or TV. When patients were diagnosed with AV or other vaginal infection, it should be mentioned whether those patients have mixed vaginal infection or AV.

    bodies larger than 5 mm, the rate of sonographic accuracy reached 100%. For foreign bodies smaller than 5 mm, 32 false positive results, and 34 false negative results were identified. One hundred thirty-nine of 181 foreign bodies were less than 2 cm from the vaginal orifice (77%). All foreign bodies were hyperechoic compared with adjacent tissues. Some vaginal foreign bodies had characteristic echo patterns. With the exception of 1 patient with a detained AAA battery that caused vaginal ulceration, the other patients had a full recovery. Vaginal foreign bodies were hyperechoic compared with adjacent tissues and often had characteristic echo patterns. The use of combined transperineal and transabdominal ultrasonography might be helpful in diagnosing foreign bodies, especially when the size of the foreign body is larger than 5 mm. Therefore, ultrasonography might be preferred for the initial evaluation of suspected vaginal foreign bodies, because it is a noninvasive, radiation-free, and inexpensive technique.

    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 withmore » 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.« less

    Purpose: We used the Female Sexual Function Index (FSFI) to investigate the prevalence of sexual dysfunction (SD) and factors associated with diminished sexual functioning in early stage endometrial cancer (EC) patients treated with simple hysterectomy and adjuvant brachytherapy. Methods and Materials: A cohort of 104 patients followed in a radiation oncology clinic completed questionnaires to quantify current levels of sexual functioning. The time interval between hysterectomy and questionnaire completion ranged from <6 months to >5 years. Multivariate regression was performed using the FSFI as a continuous variable (score range, 1.2-35.4). SD was defined as an FSFI score of <26, basedmore » on the published validation study. Results: SD was reported by 81% of respondents. The mean ({+-} standard deviation) domain scores in order of highest-to-lowest functioning were: satisfaction, 2.9 ({+-}2.0); orgasm, 2.5 ({+-}2.4); desire, 2.4 ({+-}1.3); arousal, 2.2 ({+-}2.0); dryness, 2.1 ({+-}2.1); and pain, 1.9 ({+-}2.3). Compared to the index population in which the FSFI cut-score was validated (healthy women ages 18-74), all scores were low. Compared to published scores of a postmenopausal population, scores were not statistically different. Multivariate analysis isolated factors associated with lower FSFI scores, including having laparotomy as opposed to minimally invasive surgery (effect size, -7.1 points; 95% CI, -11.2 to -3.1; P<.001), lack of vaginal lubricant use (effect size, -4.4 points; 95% CI, -8.7 to -0.2, P=.040), and short time interval (<6 months) from hysterectomy to questionnaire completion (effect size, -4.6 points; 95% CI, -9.3-0.2; P=.059). Conclusions: The rate of SD, as defined by an FSFI score <26, was prevalent. The postmenopausal status of EC patients alone is a known risk factor for SD. Additional factors associated with poor sexual functioning following treatment for EC included receipt of laparotomy and lack of vaginal lubricant use.« less

    Adverse outcomes after surgery for pelvic organ prolapse (POP) with mesh are often attributed to the mesh material with little attention paid to the influence of surgeon factors. We used a national data set to determine whether surgeon case volume and specialty influenced vaginal prolapse surgery outcomes with mesh. Public Use File data on a 5% random national sample of female Medicare beneficiaries were obtained from the Centers for Medicare and Medicaid Services. Women with a diagnosis of POP who underwent surgery with mesh between 2007 and 2008 were identified by relevant International Classification of Diseases, 9th Revision, Clinical Modification and Current Procedural Terminology, 4th Edition procedure codes. Outcomes were compared by surgeon case volume and specialty. From 2007 to 2008, 1657 surgeries for POP were performed with mesh. Low-, intermediate-, and high-volume surgeons performed 881 (53%), 408 (25%), and 368 (22%) of the cases with mesh, respectively. The cumulative reoperation rates for low-, intermediate-, and high-volume providers were 6%, 2%, and 3%, respectively. The difference in reoperation rates between low and intermediate and low- and high-volume surgeons was statistically significant (P = 0.007 and 0.003, respectively). There was no significant difference in reoperation rates between gynecologists and urologists when vaginal mesh was implanted for POP surgery. Low-volume surgeons performed most of the vaginal prolapse repairs with mesh and had significantly higher reoperation rates. Surgeon experience must be a consideration when reporting mesh-related complications of POP surgery.

    Brachytherapy is integral to vaginal cancer treatment and is typically delivered using an intracavitary single-channel vaginal cylinder (SCVC) or an interstitial brachytherapy (ISBT) applicator. Multi-channel vaginal cylinder (MCVC) applicators allow for improved organ-at-risk (OAR) sparing compared to SCVC while maintaining target coverage. We present clinical outcomes of patients treated with image-based high dose-rate (HDR) brachytherapy using a MCVC. Sixty patients with vaginal cancer (27% primary vaginal and 73% recurrence from other primaries) were treated with combination external beam radiotherapy (EBRT) and image-based HDR brachytherapy utilizing a MCVC if residual disease thickness was 7 mm or less after EBRT. All pts received 3D image-based BT to a total equivalent dose of 70-80 Gy. The median high-risk clinical target volume was 24.4 cm 3 (interquartile range [IQR], 14.1), with a median dose to 90% of 77.2 Gy (IQR, 2.8). After a median follow-up of 45 months (range, 11-78), the 4-year local-regional control, distant control, DFS, and OS rates were 92.6%, 76.1%, 64.0%, and 67.2%, respectively. The 4-year LRC rates were similar between the primary vaginal (92%) and recurrent (93%) groups (p = 0.290). Pts with lymph node positive disease had a lower rate of distant control at 4 years (22.7% vs. 89.0%, p < 0.001). There were no Grade 3 or higher acute complications. The 4-year rate of late Grade 3 or higher toxicity was 2.7%. Clinical outcomes of pts with primary and recurrent vaginal cancer treated definitively in a systematic manner with combination EBRT with image-guided HDR BT utilizing a MCVC applicator demonstrate high rates of local control and low rates of severe morbidity. The MCVC technique allows interstitial implantation to be avoided in select pts with ≤7 mm residual disease thickness following EBRT while maintaining excellent clinical outcomes with extended 4-year follow-up in this rare malignancy.

    The vaginal surgeon is challenged with performing complex procedures within a surgical field of limited light and exposure. The video telescopic operating microscope is an illumination and imaging system that provides visualization during open surgical procedures with a limited field of view. The imaging system is positioned within the surgical field and then secured to the operating room table with a maneuverable holding arm. A high-definition camera and Xenon light source allow transmission of the magnified image to a high-definition monitor in the operating room. The monitor screen is positioned above the patient for the surgeon and assistants to view real time throughout the operation. The video telescopic operating microscope system was used to provide surgical illumination and magnification during total vaginal hysterectomy and salpingectomy, midurethral sling, and release of vaginal scar procedures. All procedures were completed without complications. The video telescopic operating microscope provided illumination of the vaginal operative field and display of the magnified image onto high-definition monitors in the operating room for the surgeon and staff to simultaneously view the procedures. The video telescopic operating microscope provides high-definition display, magnification, and illumination during vaginal surgery.

    To investigate the safety and clinical efficacy of uterime artery chemoembolization in postpartum hemorrhage (PPH) caused by abnormal placental implantation. Between December 2006 and September 2009, there were 23 cases of abnormal placental implantation with PPH in our hospital, among which 9 presented with continuous small amount of vaginal bleeding and 14 with acute excessive bleeding. The average bleeding time was (8+/-6) d and the mean blood loss was (980+/-660) ml. Abnormal placental implantation was confirmed by color Doppler ultrasound (CD-US) in all cases, the internal iliac artery angiography was performed to identify the uterine artery and bilateral uterine artery chemoembolization (UACE) with methotrexate (MTX) and gelfoam particles to the distal end of uterine artery was conducted after. CD-US rechecked all patients within 48 h after UACE and those patients with blurred margins between placenta and uterus and abnormal blood flow (>1 cmx1 cm) received ultrasonic-guided per vagina MTX multipoint injections. All cases were followed up for 3-26 months (average 12 months) to observe vaginal bleeding, placenta tissue discharge, serum human chorionic gonadotropin (hCG), uterine involution, menses, and side-effects or complications. (1) Curative effect: These 23 cases underwent 24 procedures of UACE successfully and vaginal bleeding ceased at an average of (3.5+/-1.3) min after UACE. Reduced blood flow in the placental implantation area was detected under CD-US after UACE. Among the 23 patients, wterine curettage was required in 16 cases due to retained placenta tissues with the mean blood loss of (40+/-28) ml during the operation, 2 underwent subtotal hysterectomy and confirmed to be placenta percreta by pathology examination, and placenta tissues were spontaneously discharged completely in 5 cases. Totally, 91% of the patients (21/23) reserved their uterus. (2) FOLLOW-UP: the serum hCG reduced to normal within 1-13 d after the placenta tissue were evacuated

    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

    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.

    Objective: To investigate the occurrence and degree of radiation-induced injury in vagina after radical radiotherapy of cervical cancer. Methods: A total of 282 cases of patients with cervical cancer were collected from November 2016 to September 2017. All of the above patients underwent radical radiotherapy from 2008 to 2017 in the First Affiliated Hospital of Xi ' an Jiaotong University. The patients' International Federation of Gynecology and Obstetrics (FIGO) staging (2009) , brachytherapy dose, whether receive synchronous chemotherapy or not, age and body mass index (BMI) for the occurrence and severity of vaginal radiation injury at different time periods were analyzed by cross-sectional survey method. The single factor would be analyzed by the method of Chi-square test and the multiple factors would be analyzed by logistic regression method to checkout. Results: Of the 282 patients, the incidence of radiation-injury in vaginal was 84.4% (238/282) , with the incidence rate of degree Ⅰ,Ⅱ and Ⅲ radiation injury were respectively 50.7% (143/282), 29.8% (84/282) and 3.9% (11/282; χ(2)=153.375, P< 0.05) , and there was no degree Ⅳ. Until the end of the follow-up time, the incidence of radiation-induced injury in vaginal after completing the treatment within 1 year, 1-2 years,>2-<5 years and ≥5 years were respectively 80.0% (24/30) , 87.2% (102/117) , 88.2% (60/68) and 77.6% (52/67; χ(2)=4.231, P= 0.238) . There were 30 cases be followed within 1 year after treatment, the incidence rate of degreeⅠ,Ⅱ and Ⅲ of radiation injury in vagina was 60.0% (18/30) , 20.0% (6/30) and 0, respectively (χ(2)=28.636, P< 0.05).

    The most common causes of vaginal/vestibular masses in the bitch are vaginal prolapse, vaginal neoplasia, and urethral neoplasia protruding into the vaginal vault. Other possible causes are clitoral enlargement, vaginal polyps, uterine prolapse, and vaginal abscessation or hematoma. Vaginal prolapse usually can be distinguished from neoplasia by the age of the patient, the time of occurrence during the estrous cycle, and the site of origin of the mass. Prolapse usually occurs in bitches under 4 years of age during proestrus, estrus, or at the end of diestrus and usually arises from the floor of the vagina, except for urethral tumors that protrude from the external urethral orifice. Appropriate diagnostic workup of bitches with vaginal vestibular masses includes complete history and physical examination, vaginal cytologic and vaginoscopic examination, retrograde vaginography or urethrocystography, serum progesterone and estradiol concentrations, and, in the case of suspect neoplasms, surgical or excision biopsy of the mass.

    To compare the clinical and microbiological results between patients with infectious vaginitis receiving vaginal irrigation with saline or no irrigation before standard antibiotic therapy. Women with vaginitis (n = 109) were randomized to receive vaginal irrigation with saline or no irrigation before standard antibiotic therapy. The vaginal symptoms perceived by subjects and clinical findings were assessed with a standardized scale during four follow-up visits, and Gram stain Nugent scores and vaginal fluid cultures were analyzed at each visit. Vaginal discharge (z = 7.159; p < 0.001), pruritus (z = 5.169; p < 0.001), itching (z = 2.969; p < 0.003) and odor scores (z = 2.303; p < 0.021) were significantly reduced in the study group compared to the control group between the first visit and 3-5 days after irrigation, before the start of antibiotic therapy. The second and third visits (15 and 30-45 days after antibiotic therapy) showed that the patients' symptoms and amounts of visible vaginal discharge did not differ between the two groups. Moreover, the microbiological cures of patients in each group did not differ at these visits (z = 0.447; p = 0.655). Vaginal irrigation with saline significantly reduces self-reported symptoms in the short term but has no effect on long-term clinical and laboratory results in women with infectious vaginitis.

    The purpose of this study was to examine whether or not vaginal elasticity or lack of lubrication is associated with deep or superficial dyspareunia. We investigated gynecological cancer survivors treated with radiation therapy. In a population-based study with 616 women answering a questionnaire (participation rate 78%) and who were treated with radiotherapy for gynecological cancer, we analyzed information from 243 women (39%) who reported that they had had intercourse during the previous six months. Analyses included log-binomial regression (relative risks) and multiple imputations by chained equations in combination with Bayesian Model Averaging, yielding a posterior probability value. Age range of this cancer recurrent-free group of women was 29-80. Dyspareunia affected 164 of 243 of the women (67%). One hundred thirty-four women (55%) reported superficial pain, 97 women (40%) reported deep pain, and 87 women (36%) reported both types of dyspareunia. The relative risk (RR) of deep dyspareunia was 1.87 (CI 1.41-2.49) with impaired vaginal elasticity compared to normal vaginal elasticity. Age and lower abdominal swelling were separate risk factors for deep dyspareunia. However, effects remain after adjusting for these factors. The relative risk of deep dyspareunia was almost twice as high with impaired vaginal elasticity compared to normal vaginal elasticity. If we wish to treat or even prevent deep dyspareunia in women with gynecological cancer, we may use our knowledge of the pathophysiology of deep dyspareunia and increasingly provide dilators together with instructions on how to use them for stretching exercises in order to retain vaginal elasticity. Results highlight the need for studies with more precise questions distinguishing superficial from deep dyspareunia so that in the future we may be able to primarily try to avoid reduced vaginal elasticity and secondarily reduce the symptoms.

    Background There is limited information on rates of STIs in Jamaica due to syndromic management and limited aetiological surveillance. We examined the prevalence of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Trichomonas vaginalis (TV) and characteristics associated with STIs among sexually active women who participated in a randomised trial of a progestin implant initiation in Jamaica (the Sino-Implant Study (SIS)). Methods SIS was a randomised trial conducted in Kingston, Jamaica, from 2012 to 2014 to evaluate whether initiation of the Sino-Implant (II) led to more unprotected sex among women ages 18–44 years. Data collected included self-reported demographic, sexual behaviour information; and vaginal swabs collected at baseline, 1-month and 3-month follow-up visits for a biomarker of recent semen exposure (prostate-specific antigen (PSA)) and for STIs. We examined associations between STIs and PSA, demographics, sexual behaviour and insertion of an implant, with a repeated-measures analysis using generalised estimating equations (SAS Institute, V.9.3). Results Remnant vaginal swabs from 254 of 414 study participants were tested for STIs. At baseline, 29% of participants tested for STIs (n=247) had laboratory-confirmed CT, 5% NG, 23% TV and 45% any STI. In a repeated-measures analysis adjusted for study arm (immediate vs delayed implant insertion), those with PSA detected did not have an increased prevalence of any STI (prevalence ratio (PR)=1.04 (95% CI 0.89 to 1.21)), whereas prevalence decreased for each 1-year increase in age (PR=0.98 (95% CI 0.97 to 0.99)). Immediate implant insertion was not associated with increases in any STI in subsequent visits (PR=1.09 (95% CI 0.94 to 1.27)). Conclusions Although the prevalence of laboratory-confirmed STIs was high, the immediate initiation of a contraceptive implant was not associated with higher STI prevalence rates over 3 months.

    There have been conflicting reports of altered vaginal microbiota and infection susceptibility associated with contraception use. The objectives of this study were to determine if intrauterine contraception altered the vaginal microbiota and to compare the effects of a copper intrauterine device (Cu-IUD) and a levonorgestrel intrauterine system (LNG-IUS) on the vaginal microbiota. DNA was isolated from the vaginal swab samples of 76 women using Cu-IUD (n=36) or LNG-IUS (n=40) collected prior to insertion of intrauterine contraception (baseline) and at 6 months. A third swab from approximately 12 months following insertion was available for 69 (Cu-IUD, n=33; LNG-IUS, n=36) of these women. The V4 region of the bacterial 16S rRNA-encoding gene was amplified from the vaginal swab DNA and sequenced. The 16S rRNA gene sequences were processed and analyzed using the software package mothur to compare the structure and dynamics of the vaginal bacterial communities. The vaginal microbiota from individuals in this study clustered into 3 major vaginal bacterial community types: one dominated by Lactobacillus iners, one dominated by Lactobacillus crispatus and one community type that was not dominated by a single Lactobacillus species. Changes in the vaginal bacterial community composition were not associated with the use of Cu-IUD or LNG-IUS. Additionally, we did not observe a clear difference in vaginal microbiota stability with Cu-IUD versus LNG-IUS use. Although the vaginal microbiota can be highly dynamic, alterations in the community associated with the use of intrauterine contraception (Cu-IUD or LNG-IUS) were not detected over 12 months. We found no evidence that intrauterine contraception (Cu-IUD or LNG-IUS) altered the vaginal microbiota composition. Therefore, the use of intrauterine contraception is unlikely to shift the composition of the vaginal microbiota such that infection susceptibility is altered. Copyright © 2017 Elsevier Inc.

  5. The vaginal microbiome: rethinking health and diseases

    Ma, Bing; Forney, Larry J.; Ravel, Jacques

    2013-01-01

    Vaginal microbiota form a mutually beneficial relationship with their host and have major impact on health and disease. In recent years our understanding of vaginal bacterial community composition and structure has significantly broadened as a result of investigators using cultivation-independent methods based on the analysis of 16S ribosomal RNA (rRNA) gene sequences. In asymptomatic, otherwise healthy women, several kinds of vaginal microbiota exist, the majority often dominated by species of Lactobacillus, while others comprise a diverse array of anaerobic microorganisms. Bacterial vaginosis is the most common vaginal conditions and is vaguely characterized as the disruption of the equilibrium of the ‘normal’ vaginal microbiots. A better understanding of ‘normal’ and ‘healthy’ vaginal ecosystems that is based on its ‘true’ function and not simply on its composition would help better define health and further improve disease diagnostics as well as the development of more personalized regimens to promote health and treat diseases.

    This article aims to review the risk stratification of endometrial cancer, treatment rationale, outcomes, treatment planning, and treatment recommendations of vaginal brachytherapy (VBT) in the post-operative management of endometrial cancer patients. The authors performed a thorough review of the literature and reference pertinent articles pertaining to the aims of this review. Adjuvant VBT for early stage endometrial cancer patients results in very low rates of vaginal recurrence (0–3.1%) with low rates of late toxicity which are primarily vaginal in nature. PORTEC-2 supports that VBT results in non-inferior rates of vaginal recurrence compared to external beam radiotherapy (EBRT) for the treatment of high-intermediate risk patients. VBT as a boost following EBRT, in combination with chemotherapy, and for high-risk histologies have shown excellent results as well though randomized data do not exist supporting VBT boost. There are many different applicators, dose-fractionation schedules, and treatment planning techniques which all result in favorable clinical outcomes and low rates of toxicity. Recommendations have been published by the American Brachytherapy Society and the American Society of Radiation Oncology to help guide practitioners in the use of VBT. Data support that patients and physicians both prefer joint decision-making regarding the use of VBT, and patients often desire additional treatment for a marginal benefit in risk of recurrence. Discussions regarding adjuvant therapy for endometrial cancer are best performed in a multi-disciplinary setting and patients should be counseled properly regarding the risks and benefits of adjuvant therapy.

    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. Copyright © 2015 John Wiley & Sons, Ltd.

    Polypropylene mesh implants for the correction of pelvic organ prolapse (POP) are now available in Japan. We developed an innovative approach for correcting POP by placing polypropylene mesh transvaginally with laparoscopic assistance. From June 2007 through March 2010, sixteen consecutive patients with symptomatic stage 2 or 3 pelvic organ prolapse underwent the laparoscopic-assisted tension-free vaginal mesh procedure at Okayama University Hospital. All patients were evaluated before and at 1, 3, 6, and 12 months after surgery. Female sexual function was also evaluated with the Female Sexual Function Index (FSFI). The procedure was performed successfully without significant complications. Fifteen of 16 patients were considered anatomically cured (93.8%) at 12 months postoperatively. One patient with a recurrent stage 3 vaginal vault prolapse required sacral colpopexy six months postoperatively. Total FSFI scores improved significantly from 10.3 ± 1.3 at baseline to 18.0 ± 1.2 at 12 months after surgery. The laparoscopic-assisted trans-vaginal mesh is a safe, effective, and simple procedure for POP repairs. The procedure not only restores anatomic relationships but also improves sexual function.

    Chronic vaginal discharge in children and adolescents is a common gynaecological complaint which is often resistant to antibiotic treatment. We present a 14 years old, premenarcheal girl who presented to us with the complaints of recurrent, foul smelling purulent occasionally blood stained vaginal discharge for eight years, where a foreign body in the upper vagina was found after releasing a dense adhesion of the lower vagina which was unable to detect by pelvic ultrasound.

    The significance of Streptococcus agalactiae as an aetiological agent in vaginitis was evaluated. A total of 6226 samples from women who presented with vaginal symptoms was examined. The presence of >10 leucocytes/high-power field (h.p.f.) was taken to be the criterion of active infection. S. agalactiae was isolated from 10.1% of these samples. The isolation rates of other common pathogens such as Candida spp., Gardnerella vaginalis and Trichomonas spp. were 54.1%, 27.2% and 4.2%, respectively, in the same group of patients. In contrast, the isolation rates of these micro-organisms in the group of patients who had no infection (<10 leucocytes/h.p.f.) were 4.2%, 38.3%, 33% and 0.5%, respectively. In the majority of samples from which S. agalactiae was isolated, it was the sole pathogen isolated (83%) and its presence was associated with an inflammatory response in 80% of patients. Furthermore, the relative risk of vaginal infection with S. agalactiae (2.38) in patients with purulent vaginal discharge was greater than that of Candida spp. infection (1.41) and lower than that of Trichomonas spp. infection (8.32). These data suggest that S. agalactiae in symptomatic women with microscopic evidence of inflammation should be considered a causative agent of vaginitis.

    We evaluated the use of vaginal implant transmitters (VITs) as a means of detecting, capturing, and radio collaring Rocky Mountain bighorn sheep ( Ovis canadensis canadensis) lambs to estimate survival and to facilitate carcass recovery to assess causes of mortality. We focused on one of several bighorn herds in Colorado, US, suffering from depressed recruitment that was not preceded by a classic all-age die-off. We captured, radio-collared, diagnosed pregnancy by ultrasound examination, and inserted VITs into 15 pregnant ewes from a herd residing near Granite, Colorado. We were subsequently able to collar a lamb from each of 13 VITs, and two additional lambs opportunistically from ewes without transmitters. As lambs died, we recovered and submitted carcasses for necropsy and laboratory assessment. All lambs captured and one additional lamb (carcass found opportunistically) were dead by about 130 d of age: 11 died of apparent pneumonia (all within 8-10 wk of age), one died from trauma after being kicked or trampled, one was killed by a mountain lion ( Puma concolor ), and three died of starvation likely caused by abandonment after capture. Pneumonic lambs had involvement of Mycoplasma ovipneumoniae and leukotoxigenic Bibersteinia trehalosi . The use of VITs and lamb collars enabled us to efficiently identify pneumonia as the predominant cause of depressed lamb recruitment in this herd; however, we urge care in neonatal lamb handling to minimize abandonment.

    Complex foldings of the vaginal wall are unique to some cetaceans and artiodactyls and are of unknown function(s). The patterns of vaginal length and cumulative vaginal fold length were assessed in relation to body length and to each other in a phylogenetic context to derive insights into functionality. The reproductive tracts of 59 female cetaceans (20 species, 6 families) were dissected. Phylogenetically-controlled reduced major axis regressions were used to establish a scaling trend for the female genitalia of cetaceans. An unparalleled level of vaginal diversity within a mammalian order was found. Vaginal folds varied in number and size across species, and vaginal fold length was positively allometric with body length. Vaginal length was not a significant predictor of vaginal fold length. Functional hypotheses regarding the role of vaginal folds and the potential selection pressures that could lead to evolution of these structures are discussed. Vaginal folds may present physical barriers, which obscure the pathway of seawater and/or sperm travelling through the vagina. This study contributes broad insights to the evolution of reproductive morphology and aquatic adaptations and lays the foundation for future functional morphology analyses. PMID:28362830

    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. 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. 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. 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. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

    Forensic analysis of biological traces generally encompasses the investigation of both the person who contributed to the trace and the body site(s) from which the trace originates. For instance, for sexual assault cases, it can be beneficial to distinguish vaginal samples from skin or saliva samples. In this study, we explored the use of microbial flora to indicate vaginal origin. First, we explored the vaginal microbiome for a large set of clinical vaginal samples (n = 240) by next generation sequencing (n = 338,184 sequence reads) and found 1,619 different sequences. Next, we selected 389 candidate probes targeting genera or species and designed a microarray, with which we analysed a diverse set of samples; 43 DNA extracts from vaginal samples and 25 DNA extracts from samples from other body sites, including sites in close proximity of or in contact with the vagina. Finally, we used the microarray results and next generation sequencing dataset to assess the potential for a future approach that uses microbial markers to indicate vaginal origin. Since no candidate genera/species were found to positively identify all vaginal DNA extracts on their own, while excluding all non-vaginal DNA extracts, we deduce that a reliable statement about the cellular origin of a biological trace should be based on the detection of multiple species within various genera. Microarray analysis of a sample will then render a microbial flora pattern that is probably best analysed in a probabilistic approach.

  15. The Efficacy of Ultraviolet Radiation for Sterilizing Tools Used for Surgically Implanting Transmitters into Fish

    Telemetry is frequently used to examine the behavior of fish, and the transmitters used are normally surgically implanted into the coelom of fish. Implantation requires the use of surgical tools such as scalpels, forceps, needle holders, and sutures. When several fish are implanted consecutively for large telemetry studies, it is common for surgical tools to be sterilized or, at minimum, disinfected between each use so that pathogens that may be present are not spread among fish. However, autoclaving tools can take a long period of time, and chemical sterilants or disinfectants can be harmful to both humans and fish andmore » have varied effectiveness. Ultraviolet (UV) radiation is commonly used to disinfect water in aquaculture facilities. However, this technology has not been widely used to sterilize tools for surgical implantation of transmitters in fish. To determine its efficacy for this application, Pacific Northwest National Laboratory researchers used UV radiation to disinfect surgical tools (i.e., forceps, needle holder, stab scalpel, and suture) that were exposed to one of four aquatic organisms that typically lead to negative health issues for salmonids. These organisms included Aeromonas salmonicida, Flavobacterium psychrophilum, Renibacterium salmoninarum, and Saprolegnia parasitica. Surgical tools were exposed to the bacteria by dipping them into a confluent suspension of three varying concentrations (i.e., low, medium, high). After exposure to the bacterial culture, tools were placed into a mobile Millipore UV sterilization apparatus. The tools were then exposed for three different time periods—2, 5, or 15 min. S. parasitica, a water mold, was tested using an agar plate method and forceps-pinch method. UV light exposures of 5 and 15 min were effective at killing all four organisms. UV light was also effective at killing Geobacillus stearothermophilus, the organism used as a biological indicator to verify effectiveness of steam sterilizers. These

    Despite decades of attempts to link infectious agents to preterm birth, an exact causative microbe or community of microbes remains elusive. Culture-independent sequencing of vaginal bacterial communities demonstrates community characteristics are associated with preterm birth, although none are specific enough to apply clinically. Viruses are important components of the vaginal microbiome and have dynamic relationships with vaginal bacterial communities. We hypothesized that vaginal eukaryotic DNA viral communities (the "vaginal virome") either alone or in the context of bacterial communities are associated with preterm birth. The objective of this study was to use high-throughput sequencing to examine the vaginal eukaryotic DNA virome in a cohort of pregnant women and examine associations between vaginal community characteristics and preterm birth. This is a nested case-control study within a prospective cohort study of women with singleton pregnancies, not on supplemental progesterone, and without cervical cerclage in situ. Serial mid-vaginal swabs were obtained at routine prenatal visits. DNA was extracted, bacterial communities were characterized by 16S rRNA gene sequencing, and eukaryotic viral communities were characterized by enrichment of viral nucleic acid with the ViroCap targeted sequence capture panel followed by nucleic acid sequencing. Viral communities were analyzed according to presence/absence of viruses, diversity, dynamics over time, and association with bacterial community data obtained from the same specimens. Sixty subjects contributed 128 vaginal swabs longitudinally across pregnancy. Twenty-four patients delivered preterm. Participants were predominantly African-American (65%). Six families of eukaryotic DNA viruses were detected in the vaginal samples. At least 1 virus was detected in 80% of women. No specific virus or group of viruses was associated with preterm delivery. Higher viral richness was significantly associated with preterm

    Vulvovaginal candidiasis is known as one of the most common fungal infection among women of reproductive age and considered as an important public health problem. In recent years, due to resistance to common antifungal medication, the use of traditional medicine of anti-fungal and herbal treatment increased. Therefore the objective of this study was to determine the effects of vaginal cream, mixture of yogurt and honey and comparing it with clotrimazole vaginal cream on symptoms of Vulvovaginal candidiasis in patients. In this randomized, triple blind clinical trial of 70 non-pregnant women infected with Candidal vulvovaginitis were placed in two groups of Vaginal cream mixed of yogurt and honey recipients (N=35) and clotrimazole vaginal cream (N=35). Both groups were treated for 7 days. At the beginning of study, Clinical and laboratory signs and symptoms were registered 7 and 14 days after treatment by questionnaire, observation form and secretions culture results. Data by chi-square test, t test, McNemar tests were analyzed by SPSS version 21. Significance level of 0.05 was considered. The result of present study reveals the significant differences in symptom improvement of ' yogurt and honey, than clotrimazole group (P<0.05) and also Positive results of the first cultures (one week after treatment) in "yogurt and honey" and clotrimazole (20% versus 8.6%) and second time cultivation (14 days after treatment) (17/1% versus 8.6%) were similar and there was no significant differences between the two groups. (P>0.05) CONCLUSION: This study indicated that he therapeutic effects of vaginal cream, yogurt and honey is not only similar with clotrimazole vaginal cream but more effective in relieving some symptoms of vaginal candidiasis. Therefore, the use of this product can be suggested as an herbal remedy for candida infection treatment.

    Vaginal discomfort and/or odor are a common complaint in primary care visits by female patients. This is especially true among sexually active women of childbearing age. Because treatment varies depending upon which syndrome is present, effective treatment depends upon accurate diagnosis. The microscopic exams for diagnosing vaginal complaints are most frequently done in primary care sites. Because of this, few clinical laboratory scientists (CLSs) have the opportunity to become familiar with microscopy on this specimen type. In addition, literature on the subject is only gradually becoming available. This paper will attempt to briefly review the clinical and microscopic features of the common syndromes associated with vaginal discomfort.

    Background Next-generation sequencing (NGS) can detect many more microorganisms of a microbiome than traditional methods. This study aimed to analyze the vaginal microbiomes of Korean women by using NGS that included bacteria and other microorganisms. The NGS results were compared with the results of other assays, and NGS was evaluated for its feasibility for predicting vaginitis. Methods In total, 89 vaginal swab specimens were collected. Microscopic examinations of Gram staining and microbiological cultures were conducted on 67 specimens. NGS was performed with GS junior system on all of the vaginal specimens for the 16S rRNA, internal transcribed spacer (ITS), and Tvk genes to detect bacteria, fungi, and Trichomonas vaginalis. In addition, DNA probe assays of the Candida spp., Gardnerella vaginalis, and Trichomonas vaginalis were performed. Various predictors of diversity that were obtained from the NGS data were analyzed to predict vaginitis. Results ITS sequences were obtained in most of the specimens (56.2%). The compositions of the intermediate and vaginitis Nugent score groups were similar to each other but differed from the composition of the normal score group. The fraction of the Lactobacillus spp. showed the highest area under the curve value (0.8559) in ROC curve analysis. The NGS and DNA probe assay results showed good agreement (range, 86.2-89.7%). Conclusions Fungi as well as bacteria should be considered for the investigation of vaginal microbiome. The intermediate and vaginitis Nugent score groups were indistinguishable in NGS. NGS is a promising diagnostic tool of the vaginal microbiome and vaginitis, although some problems need to be resolved. PMID:27374709

    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 1.43–4.91), and require general anesthesia (8.0% vs 4.1%, OR 2.05 95% CI 1.44–2.91). 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.

    Single-incision transvaginal mesh for reconstruction of Level I and II prolapses in women with recurrent or advanced prolapse. We evaluated functional, anatomical, sonomorphological and quality-of-life outcome. Data were collected retrospectively for preoperative parameters and at follow-up visits. Anatomical cure was assessed with vaginal examination using the ICS-POP-Q system; introital-ultrasound scan for postvoidal residual and description of mesh characteristics was performed. We applied a visual analogue scale (VAS) and the German Pelvic Floor Questionnaire to assess quality-of-life. Seventy women with cystocele (III: 61.3%/IV: 16%), all post-hysterectomy and in majority (81.4%) after previous cystocele repair, were operated using a single-incision transvaginal technique. Overall anatomical success rate was 95.7% with significant improvement in quality-of-life (p < 0.0001). Mesh erosion occurred in 5.7%, one patient presented symptomatic vaginal vault prolapse. Postvoidal residual declined significantly (58 vs. 2.9%). Sonographic mesh length was 55.7% of implanted mesh with a wide range of mesh position, but no signs of mesh dislocation. There was no de novo dyspareunia reported, one case of preoperative existing dyspareunia worsened. No severe adverse event was observed. We hereby present a trial of a high-risk group of patients requiring reconstruction of anterior and apical vaginal wall in mostly recurrent prolapse situation. Our data support the hypothesis of improved anatomical and functional results and less mesh shrinkage caused by the single-incision technique with fixation in sacrospinous ligament in combination with modification in mesh quality compared to former multi-incision techniques.

    The aim of the paper is to identify, review, analyze, and summarize available evidence in three areas on the use of cross-sectional imaging, specifically maxillofacial cone beam computed tomography (CBCT) in pre- and postoperative dental implant therapy: (1) Available clinical use guidelines, (2) indications and contraindications for use, and (3) assessment of associated radiation dose risk. Three focused questions were developed to address the aims. A systematic literature review was performed using a PICO-based search strategy based on MeSH key words specific to each focused question of English-language publications indexed in the MEDLINE database retrospectively from October 31, 2012. These results were supplemented by a hand search and gray literature search. Twelve publications were identified providing guidelines for the use of cross-sectional radiography, particularly CBCT imaging, for the pre- and/or postoperative assessment of potential dental implant sites. The publications discovered by the PICO strategy (43 articles), hand (12), and gray literature searches (1) for the second focus question regarding indications and contraindications for CBCT use in implant dentistry were either cohort or case-controlled studies. For the third question on the assessment of associated radiation dose risk, a total of 22 articles were included. Publication characteristics and themes were summarized in tabular format. The reported indications for CBCT use in implant dentistry vary from preoperative analysis regarding specific anatomic considerations, site development using grafts, and computer-assisted treatment planning to postoperative evaluation focusing on complications due to damage of neurovascular structures. Effective doses for different CBCT devices exhibit a wide range with the lowest dose being almost 100 times less than the highest dose. Significant dose reduction can be achieved by adjusting operating parameters, including exposure factors and reducing the

    Four Lactobacillus species, namely L. crispatus , L. iners , L. gasseri , and L. jensenii , commonly dominate the vaginal communities of most reproductive-age women. It is unclear why these particular species, and not others, are so prevalent. Historically, estrogen-induced glycogen production by the vaginal epithelium has been proffered as being key to supporting the proliferation of vaginal lactobacilli. However, the 'fly in the ointment' (that has been largely ignored) is that the species of Lactobacillus commonly found in the human vagina cannot directly metabolize glycogen. It would appear that this riddle has been solved as studies have demonstrated that vaginal lactobacilli can metabolize the products of glycogen depolymerization by α-amylase, and fortunately, amylase activity is found in vaginal secretions. These amylases are presumed to be host-derived, but we suggest that other bacterial populations in vaginal communities could also be sources of amylase in addition to (or instead of) the host. Here we briefly review what is known about human vaginal bacterial communities and discuss how glycogen-derived resources and resource competition might shape the composition and structure of these communities.

    Dental implants are common method to replace decayed or broken tooth. As the implant treatment procedures varies according to the patients' jawbone, bone ridge, and sinus structure, appropriate examinations are necessary for successful treatment. Currently, radiographic examinations including periapical radiology, panoramic X-ray, and computed tomography are commonly used for diagnosing and monitoring. However, these radiographic examinations have limitations in that patients and operators are exposed to radioactivity and multiple examinations are performed during the treatment. In this study, we demonstrated photoacoustic (PA) and ultrasound (US) combined imaging of dental implant that can lower the total amount of absorbed radiation dose in dental implant treatment. An acoustic resolution PA macroscopy and a clinical PA/US system was used for dental implant imaging. The acquired dual modal PA/US imaging results support that the proposed photoacoustic imaging strategy can reduce the radiation dose rate during dental implant treatment.

    To evaluate the potential for a clinically relevant drug-drug interaction with concomitant use of a dapivirine vaginal ring, a novel antiretroviral-based HIV-1 prevention strategy, and hormonal contraception by examining contraceptive efficacies with and without dapivirine ring use. A secondary analysis of women participating in MTN-020/ASPIRE, a randomized, double-blind, placebo-controlled trial of the dapivirine vaginal ring for HIV-1 prevention. Use of a highly effective method of contraception was an eligibility criterion for study participation. Urine pregnancy tests were performed monthly. Pregnancy incidence by arm was calculated separately for each hormonal contraceptive method and compared using an Andersen-Gill proportional hazards model stratified by site and censored at HIV-1 infection. Of 2629 women enrolled, 2310 women returned for follow-up and reported using a hormonal contraceptive method at any point during study participation (1139 in the dapivirine arm and 1171 in the placebo arm). Pregnancy incidence in the dapivirine arm versus placebo among women using injectable depot medroxyprogesterone acetate was 0.43% vs. 0.54%, among women using injectable norethisterone enanthate was 1.15% vs. 0%, among women using hormonal implants was 0.22% vs. 0.69%, and among women using oral contraceptive pills was 32.26% vs. 28.01%. Pregnancy incidence did not differ by study arm for any of the hormonal contraceptive methods. Use of the dapivirine ring does not reduce the effectiveness of hormonal contraceptives for pregnancy prevention. Oral contraceptive pill use was associated with high pregnancy incidence, potentially because of poor pill adherence. Injectable and implantable methods were highly effective in preventing pregnancy.

    Objective: To determine the effect of vaginal hygiene module to attitudes and behavior of pathological vaginal discharge prevention in adolescent girls in Sleman Regency, Yogyakarta, Indonesia. Materials and methods: This present study is a quasi experiment with pretest and post-test control group design. A total of 80 female students was selected randomly from two secondary schools at the study site and then distributed equally to control and experimental group. Only participants in the experimental group were given self-learning vaginal hygiene module to maintain vaginal cleanliness. A questionnaire was used as an instrument to measure the attitudes and behavior of vaginal discharge prevention. Paired and independent sample t-tests with significance level (p value) at 0.05 and Confidence Interval (CI) of 95%were employed to compare the mean difference. Results: There is a significant difference in the students’ attitude and practice of pathological vaginal discharge prevention between intervention and control group. The students who have been exposed to vaginal hygiene module for six months showed better attitudes and practice in pathological vaginal discharge prevention compared to their counterpart in control group who do not receive any module. Conclusion: The present study implied that vaginal hygiene module can be provided widely for female adolescents at their early puberty. District health officers may work closely with schools’ health promoter to reach the students and create a supportive environment for reproductive health discussion and forum in order to achieve better adolescents’ reproductive health status.

    Gold nanoparticles (AuNPs) embedded in fused silica and sapphire dielectric matrices were synthesized by Au ion implantation. Systematic investigations were carried out to study the influence of implantation dose, post annealing temperature, swift heavy ion (SHI) irradiation and radiation enhanced diffusion (RED). Rutherford Backscattering Spectrometry (RBS) measurements were carried out to quantify concentration and depth profile of Au present in the host matrices. X-ray diffraction (XRD) was employed to characterize AuNPs formation. As-implanted and post-annealed films were irradiated using 100 MeV Ag ions to investigate the effect of electronic energy deposition on size and shape of NPs, which is estimated indirectly by the peak shape analysis of surface plasmon resonance (SPR). The effect of volume fraction of Au and their redistribution is also reported. A strong absorption in near infra red region is also noticed and understood by the formation of percolated NPs in dielectric matrices. It is quite clear from these results that the effect of RED assisted Oswald ripening is much more pronounced than the conventional Oswald ripening for the growth of NPs in the case of silica host matrices. However for sapphire matrices, it seems that growth of NPs already completed during implantation and it may be attributed to the high diffusivity of Au in sapphire matrices during implantation process.

    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

    Data evaluating the impact of contraceptives on the vaginal microbiome are limited and inconsistent. We hypothesized that women initiating copper intrauterine device use would have increased bacterial vaginosis and bacterial vaginosis-associated microbes with use compared to women initiating and using hormonal contraceptive methods. Vaginal swabs (N = 1047 from 266 participants seeking contraception) for Nugent score determination of bacterial vaginosis and quantitative polymerase chain reaction analyses for assessment of specific microbiota were collected from asymptomatic, healthy women aged 18-35 years in Harare, Zimbabwe, who were confirmed to be free of nonstudy hormones by mass spectrometry at each visit. Contraception was initiated with an injectable (depot medroxyprogesterone acetate [n = 41], norethisterone enanthate [n = 44], or medroxyprogesterone acetate and ethinyl estradiol [n = 40]), implant (levonorgestrel [n = 45] or etonogestrel [n = 48]), or copper intrauterine device (n = 48) and repeat vaginal swabs were collected after 30, 90, and 180 days of continuous use. Self-reported condom use was similar across all arms at baseline. Quantitative polymerase chain reaction was used to detect Lactobacillus crispatus, L jensenii, L gasseri/johnsonii group, L vaginalis, L iners, Gardnerella vaginalis, Atopobium vaginae, and Megasphaera-like bacterium phylotype I from swabs. Modified Poisson regression and mixed effects linear models were used to compare marginal prevalence and mean difference in quantity (expressed as gene copies/swab) prior to and during contraceptive use. Bacterial vaginosis prevalence increased in women initiating copper intrauterine devices from 27% at baseline, 35% at 30 days, 40% at 90 days, and 49% at 180 days (P = .005 compared to marginal prevalence at enrollment). Women initiating hormonal methods had no change in bacterial vaginosis prevalence over 180 days. The mean increase in Nugent score was 1.2 (95% confidence

    Introduction and hypothesis Many providers recommend concurrent estrogen therapy with pessary use to limit complications; however, limited data exist to support this practice. We hypothesized that vaginal estrogen supplementation decreases incidence of pessary-related complications and discontinuation. Methods We performed a retrospective cohort study of women who underwent a pessary fitting from 1 January 2007 through 1 September 2013 at one institution; participants were identified by billing code and were eligible if they were post-menopausal and had at least 3 months of pessary use and 6 months of follow-up. All tests were two sided, and P values < 0.05 were considered statistically significant. Results Data from 199 women were included; 134 used vaginal estrogen and 65 did not. Women who used vaginal estrogen had a longer median follow-up time (29.5 months) compared with women who did not (15.4 months) and were more likely to have at least one pessary check (98.5 % vs 86.2 %, P < 0.001). Those in the estrogen group were less likely to discontinue using their pessary (30.6 % vs 58.5 %, P < 0.001) and less likely to develop increased vaginal discharge than women who did not [hazard ratio (HR) 0.31, 95 % confidence interval (CI) 0.17–0.58]. Vaginal estrogen was not protective against erosions (HR 0.93, 95 % CI 0.54–1.6) or vaginal bleeding (HR 0.78, 95 % CI 0.36–1.7). Conclusions Women who used vaginal estrogen exhibited a higher incidence of continued pessary use and lower incidence of increased vaginal discharge than women who did not. PMID:26992727

    During climacteric the reduction or interruption of estrogenic stimulus determines a gradual atrophy of the tissues of the urogenital tract.Vulvovaginal atrophy can be cause of dryness, itch, burning, and dyspareunia. Vulvovaginal atrophy is associated also with depression. Hence the importance of an appropriate treatment of the vulvovaginal atrophy. Between therapeutic options we can add, particularly for women who suffer only from vaginal symptoms, the spa therapy that uses mineral waters with benefic effects on vaginal tissue wellness and health. On the basis of considerations described above and on the insufficient literature data, the objective of our single-arm pilot study has been to evaluate, in women suffering from vulvovaginal atrophy, the effects and safety of a vaginal douching cycle with sulphurous mineral water and impact on depression disorder frequently observed. The study was conducted on 24 women affected by vulvovaginal atrophy; mean age:57±11 years; age range:42-81 years. The subjects were treated, for 2 weeks, with sulphurous vaginal douching from Terme of Telese S.p.A. (Benevento-Italy). At the beginning and at the end of the SPA treatment the following symptoms were evaluated: dryness, burning, itch, dyspareunia and leucorrhoea (using VAS scale); the impact on psychological distress (using S.D.S. Zung-test). At the end of the spa treatment, the mean values±SD, compared to baseline, have showed a significant (p<0.05) reduction in leucorrhoea (-88%), in vulvar itch (-79%), in vaginal burning (-71%), in vaginal dryness (-65%) with an improvement of psichological distress as demonstrated by S.D.S. Zung-test. The data of this single-arm pilot clinical trial show that the sulphurous vaginal douching cycle can be considered very useful in women suffering from vulvovaginal atrophy with improving of the quality of life and social relationship.

    To retrospectively evaluate for pits along the dorsum of the pubic body in females and compare the presence/absence of these pits to vaginal birth data. We retrospectively reviewed females with vaginal birth data who underwent pelvic CT. The presence of pits along the dorsum of the pubic body, pit grade (0 = not present; 1 = faintly imperceptible; 2 = present; 3 = prominent), and the presence of osteitis condensans ilii, preauricular sulcus, and sacroiliac joint vacuum phenomenon were assessed on imaging. Musculoskeletal radiologists who were blinded to the birth data evaluated the CTs. 48 males were also evaluated for the presence of pits. 482 female patients underwent CT pelvis and 171 were excluded due to lack of vaginal birth data. Of the 311 study patients, 262 had prior vaginal birth(s) and 194 had pits on CT. Only 7 of the 49 patients without prior vaginal birth had pits. There was a statistically significant association between vaginal birth and presence of pits (p < 0.0001). Patients with more prominent pits (grades 2/3) had a greater number of vaginal births. As vaginal deliveries increased, the odds of having parturition pits greatly increased, adjusting for age and race at CT (p < 0.0001). No males had pits. Our study indicates that parturition pits are associated with prior vaginal birth and should be considered a characteristic of the female pelvis. The lytic appearance of prominent pits on imaging can simulate disease and create a diagnostic dilemma for interpreting radiologists.

    Background This review aimed to synthesize and analyze the diagnostic accuracy and the likelihood of providing correct treatment of the syndromic approach Vaginal Discharge Flowchart in managing cervical infections caused by Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT), and vaginal infections caused by Trichomonas vaginalis (TV) and Bacterial vaginosis (BV) and Candida albicans. This review will inform updating the WHO 2003 guidelines on Vaginal Discharge syndromic case management. Methods A systematic review was conducted on published studies from 01-01-2000 to 30-03-2015 in multiple databases. Studies evaluating the diagnostic accuracy and validation of the WHO Vaginal Discharge Flowchart were included. Validation parameters including sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) and the 95% confidence intervals for the different types of the flowchart were taken as outcomes, re-calculated, and analysed using a fixed model meta-analysis for data pooling. The level of agreement between the index and reference test were determined by the Cohen’s Kappa co-efficiency test. Each individual study was assessed on quality using the QUADAS-2 tool. Findings The search yielded 2,845 studies of which 16 met the eligibility criteria for final analysis. The diagnostic performance to identify cervical infections was low and resulted in a high proportion of over and missed treatment. The four flowcharts had a sensitivity between 27.37% in history and risk assessment and 90.13% with microscopy, with the inverse in specificity rates. The treatment performances between the flowcharts were inconsistent. The same applies to the use of vaginal discharge flowchart for treating vaginal infections. For vaginal infections the vaginal discharge flowchart had a good performance in flowchart 3 with 91.68% of sensitivity; 99.97% specificity; 99.93% PPV and 0.02% who missed their treatment and 8.32% of women who were over treated

    Pelvic Organ Prolapse (POP) is a major clinical burden affecting 25% of women, with vaginal delivery a major contributing factor. We hypothesised that increasing parity weakens the vagina by altering the extracellular matrix proteins and smooth muscle thereby leading to POP vulnerability. We used a modified POP-quantification (POP-Q) system and a novel pressure sensor to measure vaginal wall weakness in nulliparous, primiparous and multiparous ewes. These measurements were correlated with histological, biochemical and biomechanical properties of the ovine vagina. Primiparous and multiparous ewes had greater displacement of vaginal tissue compared to nulliparous at points Aa, Ap and Ba and lower pressure sensor measurements at points equivalent to Ap and Ba. Vaginal wall muscularis of multiparous ewes was thinner than nulliparous and had greater elastic fibre content. Collagen content was lower in primiparous than nulliparous ewes, but collagen organisation did not differ. Biomechanically, multiparous vaginal tissue was weaker and less stiff than nulliparous. Parity had a significant impact on the structure and function of the ovine vaginal wall, as the multiparous vaginal wall was weaker and had a thinner muscularis than nulliparous ewes. This correlated with “POP-Q” and pressure sensor measurements showing greater tissue laxity in multiparous compared to nulliparous ewes. PMID:28374826

    To evaluate associations between alterations in vaginal flora and clinical symptoms in low-risk pregnant women. Vaginal specimens from 245 pregnant women were analyzed by microscopy for vaginal flora. Signs and symptoms of vaginal infection were determined by patient interviews and gynecologic examinations. Abnormal vaginal flora was identified in 45.7% of the subjects. The final clinical diagnoses were bacterial vaginosis (21.6%), vaginal candidosis (10.2%), intermediate vaginal flora (5.2%), aerobic vaginitis (2.9%), mixed flora (2.9%) and other abnormal findings (2.9%). The percentage of women with or without clinical signs or symptoms was not significantly different between these categories. The presence of vaginal odor or vaginal discharge characteristics was not diagnostic of any specific flora alteration; pruritus was highly associated with candidosis (p < 0.0001). Compared to women with normal flora, pruritus was more prevalent in women with candidosis (p < 0.0001), while vaginal odor was associated with bacterial vaginosis (p = 0.0026). The prevalence of atypical vaginal flora is common in our low-risk pregnant population and is not always associated with pathology. The occurrence of specific signs or symptoms does not always discriminate between women with different types of atypical vaginal flora or between those with abnormal and normal vaginal flora.

  7. Unraveling the Dynamics of the Human Vaginal Microbiome

    2016-01-01

    Four Lactobacillus species, namely L. crispatus, L. iners, L. gasseri, and L. jensenii, commonly dominate the vaginal communities of most reproductive-age women. It is unclear why these particular species, and not others, are so prevalent. Historically, estrogen-induced glycogen production by the vaginal epithelium has been proffered as being key to supporting the proliferation of vaginal lactobacilli. However, the ‘fly in the ointment’ (that has been largely ignored) is that the species of Lactobacillus commonly found in the human vagina cannot directly metabolize glycogen. It would appear that this riddle has been solved as studies have demonstrated that vaginal lactobacilli can metabolize the products of glycogen depolymerization by α-amylase, and fortunately, amylase activity is found in vaginal secretions. These amylases are presumed to be host-derived, but we suggest that other bacterial populations in vaginal communities could also be sources of amylase in addition to (or instead of) the host. Here we briefly review what is known about human vaginal bacterial communities and discuss how glycogen-derived resources and resource competition might shape the composition and structure of these communities.

  8. Resolution of Rectal Prolapse by Vaginal Reconstruction.

    Rectal prolapse is a disorder of the pelvic floor in which the layers of the rectal mucosa protrude outward through the anus. Surgical repair is the mainstay of treatment. Options include intra-abdominal procedures such as rectopexy and perineal procedures such as the Delorme and Altemeier perineal rectosigmoidectomy. Rectal and vaginal prolapse can often coexist. However, to our knowledge, there are no reported cases of rectal prolapse resolved by the repair of a compressive enterocele abutting the anterior rectal wall through a vaginal approach alone. We present a novel case of rectal prolapse that resolved by correction of the vaginal defect. A 53-year-old female with prior history of abdominal hysterectomy, presented to the urogynecology clinic with complaints of vaginal bulge, urge urinary incontinence, and rectal bulge on straining with no fecal incontinence for several years. On physical examination, she was found to have stage 2 anterior, posterior, and apical vaginal prolapse and reducible rectal prolapse. Colorectal surgery (CRS) evaluation was requested, which revealed minimal anterior mucosal prolapse on Valsalva with no full-thickness prolapse. Magnetic resonance imaging (MRI) defecogram was performed, which demonstrated a large rectocele, enterocele, and small bowel prolapsing between the rectum and vagina during the evacuation phase, with no rectal prolapse. The decision to proceed with vaginal prolapse surgery without concomitant rectal prolapse repair was made, as the patient had no fecal incontinence, and the degree of rectal prolapse was minimal. On the day of surgery, which was 2 months later, she presented with a 2-cm anterior rectal prolapse with no incontinence. Colorectal surgery was consulted again, but unavailable. After counseling, the patient wished to proceed with her planned surgery. It was felt that correcting the anterior rectocele and enterocele, thereby eliminating the descent of the bowel on the anterior rectal wall, might cause

    Streptococcus agalactiae (group B Streptococcus, GBS), is a Gram-positive, asymptomatic colonizer of the human gastrointestinal tract and vaginal tract of 10 - 30% of adults. In immune-compromised individuals, including neonates, pregnant women, and the elderly, GBS may switch to an invasive pathogen causing sepsis, arthritis, pneumonia, and meningitis. Because GBS is a leading bacterial pathogen of neonates, current prophylaxis is comprised of late gestation screening for GBS vaginal colonization and subsequent peripartum antibiotic treatment of GBS-positive mothers. Heavy GBS vaginal burden is a risk factor for both neonatal disease and colonization. Unfortunately, little is known about the host and bacterial factors that promote or permit GBS vaginal colonization. This protocol describes a technique for establishing persistent GBS vaginal colonization using a single β-estradiol pre-treatment and daily sampling to determine bacterial load. It further details methods to administer additional therapies or reagents of interest and to collect vaginal lavage fluid and reproductive tract tissues. This mouse model will further the understanding of the GBS-host interaction within the vaginal environment, which will lead to potential therapeutic targets to control maternal vaginal colonization during pregnancy and to prevent transmission to the vulnerable newborn. It will also be of interest to increase our understanding of general bacterial-host interactions in the female vaginal tract.

Growth and metabolic viability of vaginal Lactobacillus spp. incubated with different concentrations of farnesol were determined by measuring the optical density of the cultures and with the MTT assay. Morphology of the farnesol-treated cells was evaluated using a scanning electron microscope. In vitro adherence of vaginal Lactobacillus cells treated with farnesol was determined by co-incubating with vaginal epithelial cells (VECs). The minimum inhibitory concentration (MIC) of farnesol for vaginal Lactobacillus spp. was 1500μM. No morphological changes were observed when the farnesol-treated Lactobacillus cells were compared with farnesol-free cells, and 100μM farnesol would reduce the adherence of vaginal Lactobacillus to VECs. Farnesol acted as a potential antimicrobial agent, had little impact on the growth, metabolism, and cytomorphology of the vaginal Lactobacillus spp.; however, it affected their adhering capacity to VECs. The safety of farnesol as an adjuvant for antimicrobial agents during the treatment of vaginitis needs to be studied further. Copyright © 2017 Elsevier B.V. All rights reserved.

    Colonization with Trichomonas vaginalis is a possible cause of poor pregnancy outcome. To facilitate the diagnosis of this condition during pregnancy, we conducted a prospective, multicenter study of 13,816 gravid women who were between 23rd and 26th week of gestation. Findings significantly associated with T. vaginalis colonization included a yellow, green, or bloody discharge from the vagina or cervix; abnormal odor after KOH was added to a vaginal specimen; a vaginal pH of > 5.0; and cervical friability. The amount of vaginal discharge and abnormal consistency of the discharge were also associated with T. vaginalis colonization. These findings (except for cervical bleeding and odor after the addition of KOH to a vaginal specimen, which may be influenced by the presence of other flora) are consistent with those reported elsewhere. The clinical usefulness of these features is minimal, and it is more significant that other microorganisms are makers for trichomoniasis; therefore, controlling for other flora is important in the investigation of T. vaginalis colonization.

    Vaginal aplasia occurs in 1 in 5,000-10,000 female live births. In this report, we evaluated a novel dual-force vaginoplasty technique for treatment of 11 patients with segmental vaginal aplasia. The principle of the approach is to thin the atretic part between two counteracting forces. The instrument was inserted laparoscopically into the proximal hematocolpos. Two balloon catheters, one for drainage and one for traction, were threaded over the inserter. The traction catheter was then threaded over a silicon tube, leaving the balloon in the proximal portion of the vagina and connecting across the vaginal septum to a fenestrated Teflon olive, which was positioned against the distal surface of the vaginal septum. This created a dual "pushing and pulling" force across the septum, which, over 3-4 days, pulls the upper vaginal pouch down while the vaginal dimple is pushed up. The aplastic segment becomes thin and easy to dilate and permits achievement of vaginal patency. The drainage of the hematocolpos is predominantly through the balloon catheter so postoperative wound management is facilitated. Eleven menarchal girls were diagnosed with segmental vaginal aplasia. The dual-force vaginoplasty was performed on each and was tolerated well with no operative complications. They all reported establishment of the menstrual cycle and significant improvement of pain during follow-up. Creation of a dual pushing-pulling force on the atretic vaginal segment is a feasible short procedure for management of segmental vaginal aplasia.

    The aim of the present work was the development of chitosan ascorbate nanoparticles (CSA NPs) loaded into a fast-dissolving matrix for the delivery of antibiotic drugs in the treatment of atrophic vaginitis. CSA NPs loaded with amoxicillin trihydrate (AX) were obtained by ionotropic gelation in the presence of pentasodium tripolyphosphate (TPP). Different CSA:TPP and CSA:AX weight ratios were considered and their influence on the particle size, polydispersion index and production yield were investigated. CSA NPs were characterized for mucoadhesive, wound healing and antimicrobial properties. Subsequently, CSA NPs were loaded in polymeric matrices, whose composition was optimized using a DoE (Design of Experiments) approach (simplex centroid design). Matrices were obtained by freeze-drying aqueous solutions of three hydrophilic excipients, polyvinylpirrolidone, mannitol and glycin. They should possess a mechanical resistance suitable for the administration into the vaginal cavity and should readily dissolve in the vaginal fluid. In addition to antioxidant properties, due to the presence of ascorbic acid, CSA NPs showed in vitro mucoadhesive, wound healing and antimicrobial properties. In particular, nanoparticles were characterized by an improved antimicrobial activity with respect to a chitosan solution, prepared at the same concentration. The optimized matrix was characterized by mechanical resistance and by the fast release in simulated vaginal fluid of nanoparticles characterized by unchanged size. PMID:29048359

    56 women who were diagnosed bioclinically as having a bacterial vaginal infection were studied, as were 35 women as a control group. The study was a semi-quantitative analysis of the vaginal bacterial flora, both aerobic and anaerobic. It shows that Gardnerella vaginalis and anaerobic bacteria such as Peptococcus, Peptostreptococcus, Bacteroïdes, Veillonella and Mobiluncus were associated in a statistically significant way with bacterial vaginitis. On the other hand Lactobacilli were less frequently found (p less than 0.001) than in the control group of women. The way in which the microbial flora is changed has been observed during attacks of vaginitis and is discussed, as is the importance of making the diagnosis and of treating this syndrome.

    2011-09-01

    Aerobic vaginitis (AV) is an alteration in vaginal bacterial flora that differs from bacterial vaginosis (BV). AV is characterised by an abnormal vaginal microflora accompanied by an increased localised inflammatory reaction and immune response, as opposed to the suppressed immune response that is characteristic of BV. Given the increased local production of interleukin (IL)-1, IL-6 and IL-8 associated with AV during pregnancy, not surprisingly AV is associated with an increased risk of preterm delivery, chorioamnionitis and funisitis of the fetus. There is no consensus on the optimal treatment for AV in pregnant or non-pregnant women, but a broader spectrum drug such as clindamycin is preferred above metronidazole to prevent infection-related preterm birth. The exact role of AV in pregnancy, the potential benefit of screening, and the use of newer local antibiotics, disinfectants, probiotics and immune modulators need further study. © 2011 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2011 RCOG.

    To describe a transperineal ultrasound-guided technique for implantation of electromagnetic transponders into the prostatic fossa. Patients were placed in the dorsal lithotomy position, and local anesthetic was administered. On ultrasound, the bladder, urethra, vesicourethral anastomosis, rectum, and the prostatic fossa were carefully identified. Three transponders were implanted into the prostatic fossa under ultrasound guidance in a triangular configuration and implantation was verified by fluoroscopy. Patients underwent computed tomography (CT) simulation approximately 1 week later. All patients in this study were subsequently treated with intensity modulated radiation therapy (IMRT) to the prostatic fossa. From 2008 to 2012, 180 patients received transperineal implantation of electromagnetic transponders into the prostatic fossa and subsequently received IMRT. There were no cases of severe hematuria or rectal bleeding requiring intervention. There were no grade 3 or 4 toxicities. Three patients (1.7%) had a transponder missing on the subsequent CT simulation. Thirteen patients (7.3%) had transponder migration with a geometric residual that exceeded 2 mm for 3 consecutive days (5.6%) or rotation that exceeded 10 degrees for 5 consecutive days (1.7%). These patients underwent a resimulation CT scan to identify the new transponder coordinates. A transperineal technique for implantation of electromagnetic transponders into the prostatic fossa is safe and well tolerated, with no severe toxicity after implantation. There is a low rate of transponder loss or migration.

    The vaginal microflora of a healthy asymptomatic woman consists of a wide variety of anaerobic and aerobic bacterial genera and species dominated by the facultative, microaerophilic, anaerobic genus Lactobacillus. The activity of Lactobacillus is essential to protect women from genital infections and to maintain the natural healthy balance of the vaginal flora. Increasing evidence associates abnormalities in vaginal flora during pregnancy with preterm labor and delivery with potential neonatal sequelae due to prematurity and poor perinatal outcome. Although this phenomenon is relatively common, even in populations of women at low risk for adverse events, the pathogenetic mechanism that leads to complications in pregnancy is still poorly understood. This review summarizes the current knowledge and uncertainties in defining alterations of vaginal flora in non-pregnant adult women and during pregnancy, and, in particular, investigates the issue of bacterial vaginosis and aerobic vaginitis. This could help specialists to identify women amenable to treatment during pregnancy leading to the possibility to reduce the preterm birth rate, preterm premature rupture of membranes, chorioamnionitis, neonatal, puerperal and maternal-fetal infectious diseases. Vaginal ecosystem study with the detection of pathogens is a key instrument in the prevention of preterm delivery, pPROM, chorioamnionitis, neonatal, puerperal and maternal-fetal infections.

    Stabilization of the vaginal apex (level 1) is an important component of operations to correct pelvic organ prolapse (POP). We report functional and anatomical results and patient-reported outcomes of our technique of vaginal vault fixation at the time of vaginal hysterectomy. One hundred and nine patients-mean 69 years, range 50.4-83.8; body mass index (BMI) 26.3, range 17.7-39.5-with symptomatic stage 2-3 uterine prolapse combined with stage 3-4 cystocele underwent vaginal hysterectomy with anterior vaginal wall repair; the apex was formed with high closure of the peritoneum and incorporation of the uterosacral and round ligaments. Only absorbable sutures were used. Follow-up included clinical examination with Pelvic Organ Prolapse Quantification system (POP-Q) scoring, introital ultrasonography, quality of life (QoL) Likert scale, and the German Pelvic Floor Questionnaire. Seventy patients (64%) were available for a follow-up after a mean of 2.8 years (range, 1.6-4.2). At follow-up, point C was stage 0 in 55 (78.6%) women and stage 1 in 15 (21.4%). The anterior vaginal wall was stage 0 or 1 in 35 (50%), stage 2 (no cystocele beyond the hymen) in 34 (49%), and stage 3 in 1 (1.4%). Vaginal length (VL) was 9 cm. Four women (4%) were reoperated for prolapse: two for recurrent anterior compartment prolapse and two for de novo rectocele. Postvoid residuals >150 ml were seen in 21(30%) patients preoperatively and resolved postoperatively in 20. Urgency occurred in nine (13%), stress urinary incontinence (SUI) in ten (14%), and nocturia in 19 (27%). No patient had discomfort at the vaginal vault and 62 patients (87%) reported improved QoL, which did not correlate with anatomical results. Cystocele ≥ 2° at follow-up was associated with BMI >25 (p = 0.03). Our surgical technique without permanent material offers good apical support and functional and subjective results. Anatomical improvement was achieved in all cases of cystocele repair. Recurrent cystoceles

    Twenty-two patients with Stage I through IV primary vaginal squamous cell carcinomas treated for cure with radiation therapy are reviewed, with particular emphasis on the relationship of dose to complications and local control. All but 2 patients received 4000 to 6000 rad whole pelvis irradiation plus at least one radium application. Local control was 91%, with an absolute 2-year disease-free survival of 82%. The degree of anaplasia was found to influence prognosis, with all local and distant failures resulting from high-grade lesions. The complication rate was modest, with no fistulae or serious bowel complications. An analysis of total dose (externalmore » plus radium) with respect to local failure and complications showed that no major complications occurred at a combined dose below 9000 rad. An analysis of the individual contributions of external irradiation and radium implants showed that all but one very minor complication occurred at a radium dose of 4000 rad or higher.

    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

    Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome includes vaginal agenesis with varied uterine development. The objective of this video is to illustrate our surgical technique to create a cervical and vaginal canal to relieve menstrual obstruction for a teenager with a functional uterus and vaginal agenesis. Using vaginal dissection and a mini laparotomy, a sound placed through the fundus of the uterus created an endocervical and vaginal channel to relieve her menstrual obstruction. A Foley catheter stented the cervical canal and a red rubber chest tube catheter stented the vagina until epithelization was achieved. No complications were encountered. The patient was examined with intermittent hysteroscopy with gentle dilation of the cervix. She had the red rubber catheter removed at 3 months, and she started using a small dilator. Her menses were suppressed with a gonadotropin releasing-hormone agonist allowing for complete healing. She is now 17. Her vaginal canal is well-epithelialized. Hysteroscopy confirmed a patent endocervical canal and uterine cavity. MRKH is rare. A small percentage of affected women has a functional endometrium requiring intervention for menstrual obstruction. Full vaginal reconstruction may be considered, but creation of a small canal to provide menstrual relief can be a temporary solution in those not desiring sexual function.

    Three oxide dispersion strengthened (ODS) steels with different chromium content (MA 956, MA 957 and ODM 751) were studied as candidate materials for new nuclear reactors in term of their radiation stability. The radiation damage was experimentally simulated by helium ion implantation with energy of ions up to 500 keV. The study was focused on surface and sub-surface structural change due to the ion implantation observed by mostly non-destructive techniques: positron annihilation lifetime spectroscopy and nanoindentation. The applied techniques demonstrated the best radiation stability of the steel ODM 751. Blistering effect occurred due to high implantation dose (mostly in MA 956) was studied in details.

    This study aimed to qualify relevant factors for vaginal delivery among women who underwent labor induction with vaginal dinoprostone (PGE2) insert in a Chinese tertiary maternity hospital. A retrospective study was conducted in Hubei Maternal and Child Health Hospital. A total of 1656 pregnancies that underwent labor induction with vaginal dinoprostone insert between January and August 2016 were finally included in this study. Data were analyzed using univariate and multivariable regression modeling. Of 1656 women with PGE2-induced labor at term, 396 (23.91%) gave birth by cesarean section, 1260 (76.09%) had a vaginal delivery among which 921 (55.61%) delivered vaginally within 24 h. Multivariable regression analysis showed that maternal age (p < .001, OR = 0.89, 95%CI 0.85-0.93), parity (multiparous versus nulliparous, p < .001, OR = 8.74, 95%CI 4.36-17.50), baseline fetal heart rate (p = .009, OR = 0.98, 95%CI 0.96-0.99), and birth weight (p < .001, OR = 0.37, 95%CI 0.28-0.51) were significantly correlated with vaginal delivery. Moreover, body mass index (p < .001, OR = 1.11, 95%CI 1.05-1.19), parity (multiparous versus nulliparous, p < .001, OR = 6.57, 95%CI 2.37-18.23), baseline fetal heart rate (p = .004, OR = 0.96, 95%CI 0.94-0.99), and birth weight (p < .001, OR = 0.34, 95%CI 0.21-0.54) were independent predictors of vaginal delivery within 24-h. Our findings suggested a vaginal delivery rate of 76.09% when dinoprostone vaginal insert was used for labor induction, which was markedly higher than the overall annual vaginal delivery rate of 65.1% in China during 2014. Maternal age, parity, baseline fetal heart rate, and birth weight were significant factors for vaginal delivery. This study enables us to better understand the efficiency of dinoprostone and the potential predictors of vaginal delivery in dinoprostone-induced labor, which may be helpful to guide the clinical use of dinoprostone and therefore provide better

    The vaginal flora is a complicated environment, containing dozens of microbiological species in variable quantities and relative proportions. The frequent cause of vaginal discharge is an infection or colonization with different microorganisms. Some pathologic conditions causing vaginitis are well defined yet, 7-72% of women with vaginitis may remain undiagnosed and such forms of abnormal vaginal flora neither considered as normal, nor can be called bacterial vaginosis have been termed as 'intermediate flora' and its management probably differ from that of bacterial vaginosis. It is of crucial importance in pregnant females at risk of preterm delivery. The present study has been conducted especially to elucidate this type of aerobic vaginal isolates and their culture and sensitivity towards currently used antibiotics. This study was conducted at the Microbiology Department of Fauji Foundation Hospital, Rawalpindi over a period of two years (April 2004-March 2006). One thousand, nine hundred and twenty three high vaginal swabs, both from indoor and outdoor patients were collected, cultured and their susceptibility to various antibiotics was determined. Significant growth was obtained in 731 samples. The highest frequency of infection (39.5%) was observed at 31-40 years followed by 41-50 years (35.8%). About 76% were from outdoor and 24% were from indoor patients. Staphylococcus aureus was the most prevalent vaginal pathogen at 11-60 yrs & with highest prevalence at 31-40 years followed by 41-50 years. It was a predominant pathogen in both indoor (35%) as well as outdoor (41.6%) patients, followed by enteric gram-negative bacilli and other gram-positive cocci. There were very few antibiotics among the conventionally available aminoglycosides, third generation cephalosporins, penicillin, quinolones, sulfonamides and tetracyclines possessing good sensitivity (> 80%) against any one the common aerobic vaginal pathogens.

    There is some evidence that the risk of HIV infection per heterosexual act is higher in low-income countries than in high-income countries. We hypothesize that variations in per sex-act transmission probability of HIV may in part be attributed to differences in the composition and function of the vaginal microbiota between different populations. This paper presents data that are in support of this hypothesis. Experimental and clinical studies have provided evidence that the normal vaginal microbiota plays a protective role against acquisition of HIV and other sexually transmitted infections. Epidemiological studies have convincingly shown that disturbances of the vaginal microbiome, namely intermediate flora and bacterial vaginosis, increase the risk of acquisition of HIV infection. A review of the literature found large differences in prevalence of bacterial vaginosis between different populations, with the highest prevalence rates found in black populations. Possible explanations for these differences are presented including data suggesting that there are ethnic differences in the composition of the normal vaginal microbiota. Lastly, interventions are discussed to restore and maintain a healthy vaginal environment. 2014 Wolters Kluwer Health | Lippincott Williams & Wilkins

    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.

    Although underutilized, the vaginal contraceptive ring has several advantages over other contraceptive methods that could benefit adolescents. We examined factors that may influence willingness to try the vaginal ring including: sexual and contraceptive history, genital comfort, and vaginal ring characteristics. Cross sectional Midwestern adolescent health clinics Adolescent women (N = 200; 14-18 years; 89% African-American) INTERVENTIONS/MAIN OUTCOME MEASURES: All participants received education about the vaginal ring and viewed pictures demonstrating insertion; they then completed a visual/audio computer-assisted self interview. The primary outcome variable, willingness to try the vaginal ring, was a single Likert-scale item. Over half the participants reported knowledge of the vaginal ring with healthcare providers identified as the most important source of contraceptive information. Comfort with one's genitals, insertion and removal, using alternative methods of insertion, and knowing positive method characteristics were significantly associated with willingness to try the vaginal ring. A decreased willingness to try the vaginal ring was related to concerns of the ring getting lost inside or falling out of the vagina. Willingness to try the ring was associated with positive feelings about genitals (e.g., comfort with appearance, hygiene, function). Thus, to increase willingness to try the vaginal ring among adolescents, providers should make it common practice to discuss basic female reproductive anatomy, raise awareness about female genital health and address concerns about their genitals. Providers can offer alternative insertion techniques (e.g., gloves) to make use more accessible. These strategies may increase vaginal ring use among adolescents. 2011 North American Society for Pediatric and Adolescent Gynecology. Published by Elsevier Inc. All rights reserved.

Women completed quality-of-life (QOL) questionnaires preoperatively and at 6 and 12 months. Objective success of surgery at 6 and 12 months following surgery. Secondary outcomes were subjective success, complications, QOL outcomes and patients' satisfaction. Objective success rate was 92 and 85% at 6 and 12 months, respectively. Subjective success rate was 91 and 87% at 6 and 12 months, respectively. New prolapse in nonrepaired compartments accounted for 7 of 12 (58%) failures at 12 months. Two of 4 mesh exposures required surgery. Sexual dysfunction was reported by 58% of sexually active women preoperatively and 23% at 12 months. QOL scores significantly improved at 12 months compared with baseline (P < 0.0001). Vaginal surgery using mesh and a VSD is an effective procedure for pelvic organ prolapse. However, further studies are required to establish the role of the surgery described in this study.

    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. Copyright © 2015 Elsevier B.V. All rights reserved.

    The female genital tract is an extremely rare site for Rhinosporidiosis. Here we described a 13 year old girl who presented with a slow growing polypoid fleshy mass in the posterior vaginal wall near the orifice for 6 months with scanty bleeding from the mass. The girl was admitted to hospital with profuse watery vaginal discharge. Excision of the mass was followed by histopathological examination which confirmed the diagnosis Rhinosporidiosis.

    Neonatal safety data along with national guidelines have prompted renewed interest in vaginal delivery of twins, particularly in the case of the noncephalic second twin. Yet, the rising rate of twin cesarean deliveries, coupled with the national decline in operative obstetrics, raises concerns about the availability of providers who are skilled in twin vaginal birth. Providers are key stakeholders for increasing rates of twin vaginal delivery. We surveyed a group of practicing obstetricians to explore potential barriers to the vaginal birth of twins with a focus on delivery of the noncephalic second twin. Among 107 responding providers, only 57% would deliver a noncephalic second twin by breech extraction. Providers who preferred breech extraction had a higher rate of maternal-fetal medicine subspecialty training (26.2% vs 4.3%; P<.01) and were more likely to be in an academic practice environment (36.1% vs 10.9%; P<.01) and to practice in high-volume centers that deliver >30 sets of twins annually (57.4% vs 34.8%; P=.02). Most providers (54.2%) were familiar with the findings from the recent randomized trial that demonstrated the safety of twin vaginal birth. However, knowledge of the trial was not associated statistically with a preference for breech extraction (62.3% vs 43.5%; P=.05). Providers who preferred breech extraction were more likely to agree with recent society guidelines that encourage the vaginal birth of twins (86.9% vs 63.0%; P<.01). In an adjusted analysis, the 46% of providers with a perceived need for more training were far less likely to prefer breech extraction for delivery of a noncephalic second twin (adjusted odds ratio, 0.38; 95% confidence interval, 0.16-0.95). Furthermore, 57% of providers who would not offer their patient breech extraction would be willing to consult a colleague for support with a noncephalic twin delivery. These results suggest that scientific evidence and society opinion are likely insufficient to reverse the national

    The interaction between the human host and the vaginal microbiota is highly dynamic. Major changes in the vaginal physiology and microbiota over a woman's lifetime are largely shaped by transitional periods such as puberty, menopause and pregnancy, while daily fluctuations in microbial composition observed through culture-independent studies are more likely to be the results of daily life activities and behaviours. The vaginal microbiota of reproductive-aged women is largely made up of at least five different community state types. Four of these community state types are dominated by lactic-acid producing Lactobacillus spp. while the fifth is commonly composed of anaerobes and strict anaerobes and is sometimes associated with vaginal symptoms. The production of lactic acid has been associated with contributing to the overall health of the vagina due to its direct and indirect effects on pathogens and host defence. Some species associated with non-Lactobacillus vaginal microbiota may trigger immune responses as well as degrade the host mucosa, processes that ultimately increase susceptibility to infections and contribute to negative reproductive outcomes such as infertility and preterm birth. Further studies are needed to better understand the functional underpinnings of how the vaginal microbiota affect host physiology but also how host physiology affects the vaginal microbiota. Understanding this fine-tuned interaction is key to maintaining women's reproductive health. © 2016 The Authors. The Journal of Physiology © 2016 The Physiological Society.

    Abstract The interaction between the human host and the vaginal microbiota is highly dynamic. Major changes in the vaginal physiology and microbiota over a woman's lifetime are largely shaped by transitional periods such as puberty, menopause and pregnancy, while daily fluctuations in microbial composition observed through culture‐independent studies are more likely to be the results of daily life activities and behaviours. The vaginal microbiota of reproductive‐aged women is largely made up of at least five different community state types. Four of these community state types are dominated by lactic‐acid producing Lactobacillus spp. while the fifth is commonly composed of anaerobes and strict anaerobes and is sometimes associated with vaginal symptoms. The production of lactic acid has been associated with contributing to the overall health of the vagina due to its direct and indirect effects on pathogens and host defence. Some species associated with non‐Lactobacillus vaginal microbiota may trigger immune responses as well as degrade the host mucosa, processes that ultimately increase susceptibility to infections and contribute to negative reproductive outcomes such as infertility and preterm birth.

    Vaginal carcinoma is a rare gynecological malignancy that is usually treated by radiation therapy and/or surgery combined with chemotherapy. Here, we report a case of invasive vaginal carcinoma in a young woman who underwent fertility-sparing treatment involving neoadjuvant chemotherapy and conservative surgery. A 36-year-old non-parous woman had a solid tumor in the vagina. Positron emission tomography/computed tomography showed a tumor in the vagina with high FDG uptake (SUV = 17.33) but no metastatic lesions. The patient was diagnosed with vaginal squamous cell carcinoma, FIGO stage I, T1N0M0. Because she wished to retain her fertility, neoadjuvant chemotherapy consisting of irinotecan hydrochloride and nedaplatin was initiated. After four courses of chemotherapy, partial vaginectomy was carried out and the pathological diagnosis of the residual lesion was VAIN 3. Following two further courses of the same chemotherapy, she obtained complete response, and has shown no evidence of disease for 14 months. © 2014 The Authors.

    The purpose of this study was to determine the outcomes and optimal practice patterns of definitive radiotherapy for primary vaginal cancer. Between 1993 and 2012, 49 patients were treated with definitive radiotherapy for primary vaginal cancer in three hospitals. Of these, 15 patients (31%) had clinically positive regional lymph node metastasis. A total of 34 patients (70%) received external beam radiotherapy with high-dose-rate brachytherapy (interstitial or intracavitary), and 8 (16%) (with small superficial Stage I tumors) were treated with local radiotherapy. The median follow-up was 33 months (range: 1-169 months). The 3-year overall survival (OS), disease-free survival (DFS), and loco-regional control (LRC) rates were 83%, 59% and 71%, respectively. In multivariate analysis, the histological type (P = 0.044) was significant risk factors for LRC. In Federation of Gynecology and Obstetrics (FIGO) Stage I cases, 3 of 8 patients (38%) who did not undergo prophylactic lymph node irradiation had lymph node recurrence, compared with 2 of 12 patients (17%) who underwent prophylactic pelvic irradiation. For Stage III-IV tumors, the local recurrence rate was 50% and the lymph node recurrence rate was 40%. Patients with FIGO Stage I/II or clinical Stage N1 had a higher recurrence rate with treatment using a single modality compared with the recurrence rate using combined modalities. In conclusion, our treatment outcomes for vaginal cancer were acceptable, but external beam radiotherapy with brachytherapy (interstitial or intracavitary) was needed regardless of FIGO stage. Improvement of treatment outcomes in cases of FIGO Stage III or IV remains a significant challenge. © The Author 2015.

    PurposeWe evaluated the management of transcatheter arterial embolization for postpartum hemorrhage caused by vaginal laceration.Materials and MethodsWe reviewed seven cases of patients (mean age 30.9 years; range 27–35) with intractable hemorrhages and pelvic hematomas caused by vaginal lacerations, who underwent superselective transcatheter arterial embolization from January 2008 to July 2014. Postpartum hemorrhage was evaluated by angiographic vascular mapping to determine the vaginal artery’s architecture, technical and clinical success rates, and complications.ResultsThe vaginal artery was confirmed as the source of bleeding in all cases. The artery was found to originate from the uterine artery in three cases, the uterine and obturator arteriesmore » in two, or the internal pudendal artery in two. After vaginal artery embolization, persistent contrast extravasation from the inferior mesenteric artery as an anastomotic branch was noted in one patient. Nontarget vessels (the inferior vesical artery and nonbleeding vaginal arterial branches) were embolized in one patient. Effective control of hemostasis and no post-procedural complications were confirmed for all cases.ConclusionPostpartum hemorrhages caused by vaginal lacerations involve the vaginal artery arising from the anterior trunk of the internal iliac artery with various branching patterns. Superselective vaginal artery embolization is clinically acceptable for the successful treatment of vaginal laceration hemorrhages, with no complications. After vaginal artery embolization, it is suggested to check for the presence of other possible bleeding vessels by pelvic aortography with a catheter tip at the L3 vertebral level, and to perform a follow-up assessment.« less

    Near-IR laser energy in conjunction with applied tissue cooling is being investigated for thermal remodeling of endopelvic fascia during minimally invasive treatment of female stress urinary incontinence. Previous simulations of light transport, heat transfer, and tissue thermal damage have shown that a transvaginal approach is more feasible than a transurethral approach. However, undesirable thermal insult to vaginal wall was predicted. This study explores whether an optical clearing agent (OCA) can improve optical penetration depth and completely preserve vaginal wall during subsurface treatment of endopelvic fascia. Several OCA mixtures were tested, and 100% glycerol was found to be optimal. Optical transmission studies, optical coherence tomography, reflection spectroscopy, and computer simulations of thermal damage to tissue using glycerol were performed. The OCA produced a 61% increase in optical transmission through porcine vaginal wall at 37 °C after 30 min. Monte Carlo (MC) light transport, heat transfer, and Arrhenius integral thermal damage simulations were performed. MC model showed improved energy deposition in endopelvic fascia using OCA. Without OCA, 62, 37, and 1% of energy was deposited in vaginal wall, endopelvic fascia, and urethral wall, compared with 50, 49, and 1% with OCA. Use of OCA also yielded 0.5 mm increase in treatment depth, allowing potential thermal tissue remodeling at 3 mm depth.

    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. 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. 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 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. The types of antibiotics used to treat vaginitis must be very selective in order not to kill the beneficial bacteria

    Neovaginal reconstruction is an important part of gender reassignment surgery. We report a case of stone formation at the apex of vaginal vault constructed with sigmoid colon segment. A 48-year-old woman presented with profuse vaginal discharge for 1 year. She had a history of gender reassignment surgery (male to female) in 1994, and the neovagina had been constructed with an isolated sigmoid colon. Vaginoscopy performed using a cystoscope revealed multiple calculi at the vaginal vault on the endoscopic gastrointestinal anastomosis staples that had been used to close the vault. Colon-vaginoplasty has the advantages of providing adequate lubrication, but excessive vaginal discharge could be a problem, as colon is a mucous membrane. Stone formation in the vaginal vault should be considered in cases of gender reassignment with persistent vaginal discharge. This case also highlights the use of cystoscope in visualising the upper vagina in difficult circumstances.

    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.

    Aromatase inhibitor (AI) treatment suppresses estrogen biosynthesis and causes genitourinary symptoms of menopause such as vaginal symptoms, ultimately affecting the quality of life for many postmenopausal women with breast cancer. Thus, the aim of this study was to examine vaginal gene expression in women during treatment with AIs compared with estrogen-treated women. The secondary aim was to study the presence and localization of vaginal aromatase. Vaginal biopsies were collected from postmenopausal women treated with AIs and from age-matched control women treated with vaginal estrogen therapy. Differential gene expression was studied with the Affymetrix Gene Chip Gene 1.0 ST Array (Affymetrix Inc, Santa Clara, CA) system, Ingenuity pathway analysis, quantitative real-time polymerase chain reaction, and immunohistochemistry. The expression of 279 genes differed between the 2 groups; AI-treated women had low expression of genes involved in cell differentiation, proliferation, and cell adhesion. Some differentially expressed genes were found to interact indirectly with the estrogen receptor alpha. In addition, aromatase protein staining was evident in the basal and the intermediate vaginal epithelium layers, and also in stromal cells with a slightly stronger staining intensity found in AI-treated women. In this study, we demonstrated that genes involved in cell differentiation, proliferation, and cell adhesion are differentially expressed in AI-treated women. The expression of vaginal aromatase suggests that this could be the result of local and systemic inhibition of aromatase. Our results emphasize the role of estrogen for vaginal cell differentiation and proliferation and future drug candidates should be aimed at improving cell differentiation and proliferation.

    Mesh, a synthetic graft, has been used in pelvic organ prolapse (POP) repair and stress urinary incontinence (SUI) to augment and strengthen weakened tissue. Polypropylene mesh has come under scrutiny by the US Food and Drug Administration. To examine the rates of mesh complications and invasive reintervention after the placement of vaginal mesh for POP repair or SUI surgery. This investigation was an observational cohort study at inpatient and ambulatory surgery settings in New York State. Participants were women who underwent transvaginal repair for POP or SUI with mesh between January 1, 2008, and December 31, 2012, and were followed up through December 31, 2013. They were divided into the following 4 groups based on the amount of mesh exposure: transvaginal POP repair surgery with mesh and concurrent sling use (vaginal mesh plus sling group), transvaginal POP repair with mesh and no concurrent sling use (vaginal mesh group), transvaginal POP repair without mesh but concurrent sling use for SUI (POP sling group), and sling for SUI alone (SUI sling group). The primary outcome was the occurrence of mesh complications and repeated invasive intervention within 1 year after the initial mesh implantation. A time-to-event analysis was performed to examine the occurrence of mesh erosions and subsequent reintervention. Secondary analyses of an age association (<65 vs ≥65 years) were conducted. The study identified 41 604 women who underwent 1 of the 4 procedures. The mean (SD) age of women at their initial mesh implantation was 56.2 (13.0) years. The highest risk of erosions was found in the vaginal mesh plus sling group (2.72%; 95% CI, 2.31%-3.21%) and the lowest in the SUI sling group (1.57%; 95% CI, 1.41%-1.74%). The risk of repeated surgery with concomitant erosion diagnosis was also the highest in the vaginal mesh plus sling group (2.13%; 95% CI, 1.76%-2.56%) and the lowest in the SUI sling group (1.16%; 95% CI, 1.03%-1.31%).

Ten women with perceived vaginal odor with or without discharge, douched every day for 4 weeks in an open-label, nonrandomized pilot study. Primary outcome measures included perceived vaginal odor by subject, lactobacilli score from Nugent slide, and acceptance of the Water Works douching system. Secondary outcome included the safety of using this douching device. At week 4, there was improvement in vaginal odor (P=.0006) and there was no significant change in lactobacilli score. Douching with Water Works device is associated with reduction or elimination of vaginal odor without adversely affecting the vaginal ecosystem.

    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.

    Lee, M; Lee, S; Suh, T

    Purpose: This study investigates the effects of different kinds and designs of commercialized breast implants on the dose distributions in breast cancer radiotherapy under a variety of conditions. Methods: The dose for the clinical conventional tangential irradiation, Intensity Modulated Radiation Therapy (IMRT), volumetric modulated arc therapy (VMAT) breast plans was measured using radiochromic films and stimulated luminescence dosimeter (OSLD). The radiochromic film was used as an integrating dosimeter, while the OSLDs were used for real-time dosimetry to isolate the contribution of dose from individual segment. The films were placed at various slices in the Rando phantom and between the bodymore » and breast surface OSLDs were used to measure skin dose at 18 positions spaced on the two (right/left) breast. The implant breast was placed on the left side and the phantom breast was remained on the right side. Each treatment technique was performed on different size of the breasts and different shape of the breast implant. The PTV dose was prescribed 50.4 Gy and V47.88≥95%. Results: In different shapes of the breast implant, because of the shadow formed extensive around the breast implant, dose variation was relatively higher that of prescribed dose. As the PTV was delineated on the whole breast, maximum 5% dose error and average 3% difference was observed averagely. VMAT techniques largely decrease the contiguous hot spot in the skin by an average of 25% compared with IMRT. The both IMRT and VMAT techniques resulted in lower doses to normal critical structures than tangential plans for nearly all dose analyzation.

    In fusion devices, ion retention and sputtering of materials are major concerns in the selection of compatible plasma-facing materials (PFMs), especially in the context of their microstructural conditions and surface morphologies. We demonstrate how surface roughness changes ion implantation and sputtering of materials under energetic ion irradiation. Using a new, sophisticated 3D Monte Carlo (MC) code, IM3D, and a random rough surface model, ion implantation and the sputtering yields of tungsten (W) with a surface roughness varying between 0-2 µm have been studied for irradiation by 0.1-1 keV D+, He+ and Ar+ ions. It is found that both ion backscattering and sputtering yields decrease with increasing roughness; this is hereafter called the ion radiation albedo effect. This effect is mainly dominated by the direct, line-of-sight deposition of a fraction of emitted atoms onto neighboring asperities. Backscattering and sputtering increase with more oblique irradiation angles. We propose a simple analytical formula to relate rough-surface and smooth-surface results.

    Research has demonstrated the association between vaginal orgasm and better mental health. Some theories of psychotherapy assert a link between muscle blocks and disturbances of both character and sexual function. In Functional-Sexological therapy, one focus of treatment is amelioration of voluntary movement. The present study examines the association of general everyday body movement with history of vaginal orgasm. The objective was to determine if appropriately trained sexologists could infer women's history of vaginal orgasm from observing only their gait. Women with known histories of either vaginal orgasm or vaginal anorgasmia were videotaped walking on the street, and their orgasmic status was judged by sexologists blind to their history. The concordance between having had orgasms triggered by penile-vaginal intercourse (not orgasm from direct clitoral stimulation) and raters' inferences of vaginal orgasm history based on observation of the woman's walk was the main outcome measure. In the sample of healthy young Belgian women (half of whom were vaginally orgasmic), history of vaginal orgasm (triggered solely by penile-vaginal intercourse) was diagnosable at far better than chance level (81.25% correct, Fisher's Exact Test P < 0.05) by appropriately trained sexologists. Clitoral orgasm history was unrelated to both ratings and to vaginal orgasm history. Exploratory analyses suggest that greater pelvic and vertebral rotation and stride length might be characteristic of the gait of women who have experienced vaginal orgasm (r = 0.51, P < 0.05). The discerning observer may infer women's experience of vaginal orgasm from a gait that comprises fluidity, energy, sensuality, freedom, and absence of both flaccid and locked muscles. Results are discussed with regard to previous research on gait, the effect of the musculature on sexual function, the special nature of vaginal orgasm, and implications for sexual therapy.

    During the last ten years, numerous species have been treated with deslorelin implants to induce contraception. The aims of the study were 1) to assess contraceptive efficacy of 4.7 mg subcutaneous deslorelin implants in rats, 2) to determine the latency of contraceptive effect, and 3) to determine potential side effects. Three experimental females were implanted and their estrous cycle was studied by vaginal smear. Two weeks after implantation, a male whose fertility was previously assessed with a control female, was introduced into their cage. No female conceived during the 4 mo following implantation. Additionally, 38 pet rats were recruited from clients in practice to test for potential side effects, including 6 males and 32 females with a mean age of 14 mo. Local reaction and transient weight gain during the first 2 wk, as well as behavioral changes were recorded. According to this pilot study, deslorelin implant could be used as a contraceptive method in female rats. The latency period is about 2 wk. Nevertheless, it might be possible to refine the treatment further using hormonal measurements. The duration of contraceptive effect is to be determined in an upcoming study. PMID:23277700

    Aerobic vaginitis (AV) is a newly defined clinical entity that is distinct from candidiasis, trichomoniasis and bacterial vaginosis (BV). Because of the poor recognition of AV, this condition can lead to treatment failures and is associated with severe complications, such as pelvic inflammatory disease, infertility, preterm birth and foetal infections. This review describes the diagnosis and treatment of AV and the relationship between AV and pregnancy. The characteristics of AV include severely depressed levels of lactobacilli, increased levels of aerobic bacteria and an inflamed vagina. The diagnosis is made by microscopy on wet mounts of fresh vaginal fluid, and some distinct clinical features are recognized. Vaginal suppositories that contain kanamycin or clindamycin have shown curative effects in nonpregnant women. Additionally, the application of topical probiotics can restore the vaginal flora and reduce the recurrence of AV. Clindamycin vaginal suppositories and probiotics may be a better choice for gravida with AV than metronidazole. AV requires prompt attention, and the early diagnosis and treatment of AV during pregnancy significantly improves perinatal outcomes. Further research is needed to define the pathogenesis, diagnostic criteria and standard treatment guidelines for AV.

    Finding innovative, non-invasive methods for continuously measuring body temperature minimizing human interference is important for accurate data collection. The objective of this study was to assess feasibility and accuracy of continuous body temperature measurements with loggers placed in the vaginal cavity of bitches. First, an in vitro experiment was performed to compare values obtained by temperature loggers (n = 26) to a calibrated liquid-in-glass thermometer. The mean differences between the two methods were low. Next, an in vivo experiment was performed using five healthy bitches, and values obtained by the vaginal loggers were compared to measurements collected rectally with digital thermometers. The results show that rectal and vaginal temperatures were correlated. The mean differences between rectal and vaginal temperatures were negligible. We conclude that the utilized temperature loggers provide accurate and reliable data. © 2012 Blackwell Verlag GmbH.

    our aim was to use porcine vagina to create a vaginal matrix and test its cellular biocompatibility. vagina was harvested from pigs and de-cellularised (DC) using a combination of detergents (Triton x-100 and sodium deoxycholate) and enzymes (DNAse/RNAse). the presence of cellular material, collagen structural integrity and basement membrane proteins were assessed histologically. To address cytocompatibility, porcine adipose derived-mesenchymal stem cells (AD-MSC) were harvested from abdominal fat together with vaginal epithelial cells (VEC) and seeded onto the mucosal aspect of the vaginal scaffold. Both cells populations were seeded individually and assessed histologically at days 3 and 10. MAIN OUTCOMES/RESULTS: the combination of enzymes and detergents resulted in a totally acellular matrix with very low DNA amount (control= 97.5ng/μl ± 10.8 vs DC= 40.1 ng/μl ±0.33 p=0.02). The extra cellular matrix (ECM) showed retention of collagen fibres and elastin and a 50% retention in glycosaminoglycan content; (control= 1.18μg/mg ± 0.28 DC = 1.35μg/mg ± 0.1 p=0.03) and an intact basement membrane (positive for both laminin and collagen IV). Seeded scaffolds showed cell attachment with both AD-MSC and VEC at days 3 and 10. it is possible to generate an acellular porcine vaginal matrix capable of supporting cells to reconstruct the vagina for future pre-clinical testing, and holds promise for creating clinically relevant sized tissue for human application.

    To relate vaginal breech delivery rates to the following hospital types: public, health maintenance organization, private teaching, or private nonteaching. In a retrospective study using administrative discharge data from Los Angeles County, California, we calculated the vaginal breech delivery rates of singleton breech deliveries during calendar years 1988 and 1991. Ten thousand four hundred breech deliveries were identified, 8988 (86.4%) term and 1412 (13.6%) preterm. Twelve percent (1252 of 10,400) were vaginal deliveries (10.1% term and 24.5% preterm). Term vaginal breech deliveries varied by hospital type and were more frequent in public hospitals (28.4%, 95% confidence interval [CI] 26.1%, 30.7%) and less frequent in private nonteaching hospitals (5.4%, 95% CI 4.8%, 5.9%). Term vaginal deliveries were 2.4 to 11.3 times more likely among black women and 1.3 to 6.3 times more likely for Hispanic women across all hospital types, compared with white women in private nonteaching hospitals. There was no difference in the proportion of preterm vaginal breech deliveries by hospital type (mean 24.5%). However, with the exception of public hospitals, the proportion of vaginal breech deliveries for both term and preterm deliveries varied significantly by ethnicity. The use of vaginal breech delivery varied by hospital type and patient ethnicity. Within private teaching and nonteaching hospitals, vaginal breech delivery was more likely for black women than for women of other ethnic groups. Further study is needed to understand the hospital policies or organizational factors, as well as the patient-related sociocultural and clinical factors, that contribute to those differences.

    Matrix metalloprotease (MMP) activity is increased in the postpartum vagina of wild-type (WT) animals. This degradative activity is also accompanied by a burst in elastic fiber synthesis and assembly. The mechanisms that precipitate these changes are unclear. The goals of this study were to determine how vaginal distention (such as in parturition) affects elastic fiber homeostasis in the vaginal wall and the potential significance of these changes in the pathogenesis of pelvic organ prolapse. Vaginal distention with a balloon simulating parturition resulted in increased MMP-2 and MMP-9 activity in the vaginal wall of nonpregnant and pregnant animals. This was accompanied by visible fragmented and disrupted elastic fibers in the vaginal wall. In nonpregnant animals, the abundant amounts of tropoelastin and fibulin-5 in the vagina were not increased further by distention. In contrast, in pregnant animals, the suppressed levels of both proteins were increased 3-fold after vaginal distention. Distention performed in fibulin-5-deficient (Fbln5−/−) mice with defective elastic fiber synthesis and assembly induced accelerated pelvic organ prolapse, which never recovered. We conclude that, in pregnant mice, vaginal distention results in increased protease activity in the vaginal wall but also increased synthesis of proteins important for elastic fiber assembly. Distention may thereby contribute to the burst of elastic fiber synthesis in the postpartum vagina. The finding that distention results in accelerated pelvic organ prolapse in Fbln5−/− animals, but not in WT, indicates that elastic fiber synthesis is crucial for recovery of the vaginal wall from distention-induced increases in vaginal protease activity.

    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.

    Pelvic organ prolapse (POP) is a multifactorial disease that manifests as the herniation of the pelvic organs into the vagina. Surgical methods for prolapse repair involve the use of a synthetic polypropylene mesh. The use of this mesh has led to significantly higher anatomical success rates compared with native tissue repairs, and therefore, despite recent warnings by the Food and Drug Administration regarding the use of vaginal mesh, the number of POP mesh surgeries has increased over the last few years. However, mesh implantation is associated with higher postsurgery complications, including pain and erosion, with higher consecutive rates of reoperation when placed vaginally. Little is known on how the mechanical properties of the implanted mesh itself change in vivo. It is assumed that the mechanical properties of these meshes remain unchanged, with any differences in mechanical properties of the formed mesh-tissue complex attributed to the attached tissue alone. It is likely that any changes in mesh mechanical properties that do occur in vivo will have an impact on the biomechanical properties of the formed mesh-tissue complex. The objective of the study was to assess changes in the multiaxial mechanical properties of synthetic clinical prolapse meshes implanted abdominally for up to 90 days, using a rat model. Another objective of the study was to assess the biomechanical properties of the formed mesh-tissue complex following implantation. Three nondegradable polypropylene clinical synthetic mesh types for prolapse repair (Gynemesh PS, Polyform Lite, and Restorelle) and a partially degradable polypropylene/polyglecaprone mesh (UltraPro) were mechanically assessed before and after implantation (n = 5/ mesh type) in Sprague Dawley rats for 30 (Gynemesh PS, Polyform Lite, and Restorelle) and 90 (UltraPro and Polyform Lite) days.

    This study was designed to evaluate clinical outcomes ≥2 years following surgery with polypropylene mesh and vaginal support device (VSD) in women with vaginal prolapse, in a prospective, multi-center setting. Patients re-consented for this extended follow-up (n = 110), with anatomic evaluation using Pelvic Organ Prolapse Quantification (POP-Q) and validated questionnaires to assess pelvic symptoms and sexual function. Complications were recorded (safety set; n = 121). Median length of follow-up was 29 months (range 24-34 months). The primary anatomic success, defined as POP-Q 0-I, was 69.1%; however, in 84.5% of the cases, the leading vaginal edge was above the hymen. Pelvic symptoms and sexual function improved significantly from baseline (p < 0.01). Mesh exposure rate was 9.1%. Five percent reported stress urinary incontinence and 3.3% required further prolapse surgery. These results indicate this non-anchored mesh repair is a safe and effective treatment for women with symptomatic vaginal prolapse in the medium term.

    Exploratory pilot study to determine the correlation between postmenopausal vulvovaginal symptoms and vaginal cytokine levels. Postmenopausal women (n = 34) not using menopausal hormone therapy and presenting with or without symptoms of vulvovaginal irritation were screened. Each participant underwent a vaginal examination and screening for vaginitis. A cervicovaginal lavage (CVL) with sterile saline and a peripheral blood sample were obtained. Main outcome measures were assessed by Luminex® X-map method on the Bio-Plex® platform. Main outcome measures were cervicovaginal and serum interleukin (IL)-4, IL-5, IL-10, IL-12, IL-13, TNF-α, GM-CSF, MIP-1-alpha and RANTES level. Cervicovaginal cytokines were adjusted to total protein concentration [pg/mcg protein]. Twenty-six postmenopausal women were enrolled (symptomatic: n = 15; asymptomatic: n = 11). There were no significant differences between groups: age, age at menopause, vaginal pH and all CVL and serum cytokines (IL-4, IL-5, IL-10, IL-12, IL-13, TNF-α, GM-CSF, MIP-1-alpha and RANTES). GM-CSF was the most abundant vaginal cytokine (symptomatic: 146.5 ± 165.6 pg/mcg protein; asymptomatic: 146.0 ± 173.5 pg/mcg protein; p = 0.99). Postmenopausal vulvovaginal symptoms did not correlate with vaginal inflammatory marker. There was no difference in serum or CVL cytokines between symptomatic and asymptomatic postmenopasual women. Vaginal symptoms after menopause are not related to the vaginal cytokine changes associated with loss of estrogen.

    Radiation damage to flow channel insert (FCI) materials is an important issue for the concept of dual-coolant blanket development in future fusion devices. Silicon Carbide (SiC) is one of the most suitable materials for FCI. Because of the severe radiation environment and exposure to tritium during operation it is of fundamental importance to study hydrogen isotope trapping and release in these materials. Here the trapping, detrapping, and diffusion of deuterium implanted into SiC is studied in correlation with pre- and post-damage induced under different conditions. For this, SiC samples are pre-damaged with 50 keV Ne+ ions at different temperatures (20, 200, 450, 700 °C) to different damage doses (1, 3.6, 7 dpa). Next, deuterium is introduced into the samples at 450 °C by ion implantation at 7 keV. The implanted deuterium retained in the sample is analysed using secondary ion mass spectrometry (SIMS) and thermo-stimulated desorption (TSD) measurements. The results indicate that with increasing neon damage dose, the maximum deuterium desorption occurs at higher temperatures. In contrast, when increasing neon implantation temperature for a fixed dose, the maximum deuterium desorption release temperature decreases. It is interpreted that the neon bombardment produces thermally stable traps for hydrogen isotopes and the stability of this damage increases with neon pre-implantation dose. A decrease of the trapping of implanted deuterium is also observed to occur due to damage recovery by thermal annealing during pre-implantation at the higher temperatures. Finally, direct particle bombardment induced deuterium release is also observed.

    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

Among women with the perceived contraindications, a logistic regression model was fit to compare each binary outcome between VH and RH. Models were weighted using inverse probability of treatment weights derived from propensity scores to adjust for covariate imbalance between procedures. The cohort had 692 VHs and 472 RHs. Among 160 women with uterine size ≥ 12 weeks' gestation, RH patients were less likely to have uterine debulking (adjusted odds ratio [aOR], .37; 95% confidence interval [CI], .15-.95]) than VH patients and more likely to have accordion grade ≥ 2 postoperative complications (aOR, 7.20; 95% CI, 1.46-35.42) and readmission (aOR, 15.55; 95% CI. .85-285.20). Among 272 women with prior cesarean section, RH patients were more likely to have grade ≥ 2 postoperative complications (aOR, 2.85; 95% CI, 1.29-6.30). No outcomes were significantly different between surgical routes among women with no vaginal parity or obesity. Mean operative time was significantly longer for RH.

    A nonsurgical laser procedure is being developed for treatment of female stress urinary incontinence (SUI). Previous studies in porcine vaginal tissues, ex vivo, as well as computer simulations, showed the feasibility of using near-infrared laser energy delivered through a transvaginal contact cooling probe to thermally remodel endopelvic fascia, while preserving the vaginal wall from thermal damage. This study explores optical properties of vaginal tissue in cadavers as an intermediate step towards future pre-clinical and clinical studies. Optical clearing of tissue using glycerol resulted in a 15-17% increase in optical transmission after 11 min at room temperature (and a calculated 32.5% increase at body temperature). Subsurface thermal lesions were created using power of 4.6 - 6.4 W, 5.2-mm spot, and 30 s irradiation time, resulting in partial preservation of vaginal wall to 0.8 - 1.1 mm depth.

    Traditional practice after vaginal hysterectomy was to keep the vaginal pack and urinary catheter for 24 hours post operatively. But there were studies that prolonged cathterisation was associated with urinary infection. So this study was conducted to compare the post operative outcome when the urinary catheter and vaginal pack were removed after 3 hours and after 24 hours after surgery. The study was done in the Department of Obstetrics and Gynecology, in a tertiary teaching institute of South India from September 2008 to March 2010. It was a randomised controlled trial involving 200 women undergoing vaginal surgery, who were randomly assigned to 2 groups - catheter and vaginal pack were removed either in 3 h in study group or were removed in 24 h in control group. The outcome of the study were vaginal bleeding, urinary retention, febrile morbidity, and urinary infection. There was no significant difference between the study and control groups with respect to vaginal bleeding (0 and 1%, p = 1), urinary retention (9 and 4%, p = 0.15), febrile morbidity (7 and 4%, p = 0.35), and urinary infection (26% in each group, p = 1.0). Keeping the urinary catheter and vaginal pack for 24 h following vaginal surgery does not offer any additional benefit against removing them after 3 h.

    To demonstrate the technique of laparoscopic vaginal reconstruction in a rare case of mid-vaginal septum with secondary infertility. A step-by-step explanation of the technique using videos and pictures (Canadian Task Force classification IV). Transverse vaginal septum is a rare condition, with an incidence of only 1 in 30,000 women. It is usually a congenital mullerian fusion defect; few cases of acquired septum have been reported. Roughly 40% of cases occur in the mid-vagina. Transverse vaginal septum typically presents with primary amenorrhea and hematocolpos. The goal of surgery is to create a patent vagina with restoration of fertility. The laparoscopic approach has proven superiority over the open technique. Laproscopic vaginal reconstruction was performed in a 24 year female with transverse vaginal septum. Dissection was done laproscopically up to mid vagina. Incision was given on vagina excising the septum followed by reconstruction. The laparoscopic approach to vaginal reconstruction avoids the abdominal incision, with its associated pain and possible adhesion formation. It also provides a better view for dissection. In this patient, a patent vagina was created in a single operation, with no postoperative dyspareunia, and fertility was restored. Copyright © 2016 AAGL. Published by Elsevier Inc.

    Bacterial vaginosis (BV) and complicated vulvovaginal candidiasis (VVC) are frequently occurring vaginal infections in postmenopausal women, caused by an imbalance in vaginal microflora. Postmenopausal women suffer from decreased ovarian hormones estrogen and progesterone. A normal, healthy vaginal microflora mainly comprises Lactobacillus species (spp.), which act beneficially as a bacterial barrier in the vagina, interfering with uropathogens. During premenopausal period, estrogen promotes vaginal colonization by lactobacilli that metabolizing glycogen and producing lactic acid, and maintains intravaginal health by lowering the intravaginal pH level. A lower vaginal pH inhibits uropathogen growth, preventing vaginal infections. Decreased estrogen secretion in postmenopausal women depletes lactobacilli and increases intravaginal pH, resulting in increased vaginal colonization by harmful microorganisms (e.g., Enterobacter, Escherichia coli, Candida, and Gardnerella). Probiotics positively effects on vaginal microflora composition by promoting the proliferation of beneficial microorganisms, alters the intravaginal microbiota composition, prevents vaginal infections in postmenopausal. Probiotics also reduce the symptoms of vaginal infections (e.g., vaginal discharge, odor, etc.), and are thus helpful for the treatment and prevention of BV and VVC. In this review article, we provide information on the intravaginal mechanism of postmenopausal vaginal infections, and describes the effectiveness of probiotics in the treatment and prevention of BV and VVC.

    Bacterial vaginosis (BV) and complicated vulvovaginal candidiasis (VVC) are frequently occurring vaginal infections in postmenopausal women, caused by an imbalance in vaginal microflora. Postmenopausal women suffer from decreased ovarian hormones estrogen and progesterone. A normal, healthy vaginal microflora mainly comprises Lactobacillus species (spp.), which act beneficially as a bacterial barrier in the vagina, interfering with uropathogens. During premenopausal period, estrogen promotes vaginal colonization by lactobacilli that metabolizing glycogen and producing lactic acid, and maintains intravaginal health by lowering the intravaginal pH level. A lower vaginal pH inhibits uropathogen growth, preventing vaginal infections. Decreased estrogen secretion in postmenopausal women depletes lactobacilli and increases intravaginal pH, resulting in increased vaginal colonization by harmful microorganisms (e.g., Enterobacter , Escherichia coli , Candida , and Gardnerella ). Probiotics positively effects on vaginal microflora composition by promoting the proliferation of beneficial microorganisms, alters the intravaginal microbiota composition, prevents vaginal infections in postmenopausal. Probiotics also reduce the symptoms of vaginal infections (e.g., vaginal discharge, odor, etc.), and are thus helpful for the treatment and prevention of BV and VVC. In this review article, we provide information on the intravaginal mechanism of postmenopausal vaginal infections, and describes the effectiveness of probiotics in the treatment and prevention of BV and VVC.

    2013-01-01

    Background Most countries recommend planned cesarean section in breech deliveries, which is considered safer than vaginal delivery. As one of few countries in the western world Norway has continued to practice planned vaginal delivery in selected women. The aim of this study is to evaluate prospectively registered neonatal and maternal outcomes in term singleton breech deliveries in a Norwegian hospital during a ten years period. We aim to compare maternal and neonatal outcomes in term breech pregnancies subjected either to planned vaginal or elective cesarean section. Methods A prospective registration study including 568 women with term breech deliveries (>37 weeks) consecutively registered at Sorlandet Hospital Kristiansand between 2001 and 2011. Fetal and maternal outcomes were compared according to delivery method; planned vaginal delivery versus planned cesarean section. Results Of 568 women, elective cesarean section was planned in 279 (49%) cases and vaginal delivery was planned in 289 (51%) cases. Acute cesarean section was performed in 104 of the planned vaginal deliveries (36.3%). There were no neonatal deaths. Two cases of serious neonatal morbidity were reported in the planned vaginal group. One infant had seizures, brachial plexus injury, and cephalhematoma. The other infant had 5-minutes Apgar < 4. Twenty-nine in the planned vaginal group (10.0%) and eight in the planned cesarean section group (2.9%) (p < 0.001) were transferred to the neonatal intensive care unit. However, only one infant was admitted for ≥4 days. According to follow-up data (median six years) none of these infants had long-term sequelae. Regarding maternal morbidity, blood loss was the only variable that was significantly higher in the planned cesarean section group versus in the vaginal delivery group (p < 0.001). Conclusions Strict guidelines were followed in all cases. There were no neonatal deaths. Two infants had serious neonatal morbidity in the planned

    Adherence of type 1 piliated Escherichia coli to vaginal mucosa plays a major role in the pathogenesis of ascending urinary tract infections (UTIs) in women. Progress in understanding the mechanism of adherence to the vaginal surface could be enhanced by the utilization of well-characterized vaginal epithelial cells. The objective of this study was to immortalize vaginal epithelial cells and study their bacterial adherence properties. Primary vaginal cells were obtained from a normal post-menopausal woman, immortalized by infection with E6/E7 genes from human papillomavirus 16 (HPV 16) and cultured in serum free keratinocyte growth factor medium. Positive immunostaining with a pool of antibodies to cytokeratins 1, 5, 10 and 14 (K1, K5, K10 and K14) and to K13 confirmed the epithelial origin of these cells. The immortalized cells showed binding of type 1 piliated E. coli in a pili specific and mannose sensitive manner. This model system should facilitate studies on the interaction of pathogens with vaginal mucosal cells, an essential step in the progression of ascending UTIs in women.

    Vaginitis is the most frequent gynecological disease. It is characterized by objective and subjective signs of inflammation and differs from bacterial vaginosis (BV) which is an abnormal condition of the vaginal ecosystem caused by the excessive growth of aerobic and anaerobic flora normally present in the vagina with an increased risk of pelvic inflammatory disease (PID). The authors report the results of a study carried out at the Centre for Gynecological Infections at the Clinic of Obstetrics and Gynecology of the University of Parma. 828 patients were enrolled in the study during the period 1985-86 and 1559 patients during the two-year period 1991-92. The aim of the study was to evaluate variations in epidemiological data for vaginitis and bacterial vaginosis in the two periods examined. No significant changes were observed (p > 0.05) with regard to the prevalence of Ca, Tv and BV forms. On the other hand, there was a significant reduction (p < 0.001) in the forms sustained by other microorganisms (above all, streptococcus and enterobacteria) between the first and second periods with a parallel increase in the number of negative cases. The analysis of the age distribution of vaginitis and BV showed a reduction of other microorganisms and an increase in negative vaginal swabs in adults (> 20 years old).

    Non-Hodgkin's lymphoma presenting as a vaginal mass in pregnancy is uncommon. A 38-year-old primigravid woman presented at 27 weeks of gestation with vaginal lesions, bleeding, and discharge. Previous vaginal biopsies had been consistent with vaginal intraepithelial neoplasia 1 and lichen planus. After admission for this enlarging vaginal mass and bleeding, she was noted to have a newly palpable breast mass. Biopsy of the breast mass and subsequent re-evaluation of original vaginal biopsies were consistent with diffuse large B-cell lymphoma. She was treated with chemoimmunotherapy during pregnancy and delivered a viable neonate at term. Although benign vaginal conditions are common, non-Hodgkin's lymphoma should be considered in the differential diagnosis of persistent or enlarging vaginal lesions in pregnancy.

    Permanent implants made of titanium or its alloys are the gold standard in many orthopedic and traumatological applications due to their good biocompatibility and mechanical properties. However, a second surgical intervention is required for this kind of implants as they have to be removed in the case of children that are still growing or on patient's demand. Therefore, magnesium-based implants are considered for medical applications as they are degraded under physiological conditions. The major challenge is tailoring the degradation in a manner that is suitable for a biological environment and such that stabilization of the bone is provided for a controlled period. In order to understand failure mechanisms of magnesium-based implants in orthopedic applications and, further, to better understand the osseointegration, screw implants in bone are studied under mechanical load by means of a push-out device installed at the imaging beamline P05 of PETRA III at DESY. Conventional absorption contrast microtomography and phasecontrast techniques are applied in order to monitor the bone-to-implant interface under increasing load conditions. In this proof-of-concept study, first results from an in situ push-out experiment are presented.

    A novel, radiation- and reference base-free procedure for placement of navigated instruments and implants was developed and its practicability and precision in retrograde drillings evaluated in an experimental setting. Two different guidance techniques were used: One experimental group was operated on using the radiation- and reference base-free navigation technique (Fluoro Free), and the control group was operated on using standard fluoroscopy for guidance. For each group, 12 core decompressions were simulated by retrograde drillings in different artificial femurs following arthroscopic determination of the osteochondral lesions. The final guide-wire position was evaluated by postoperative CT analysis using vector calculation. High precision was achieved in both groups, but operating time was significantly reduced in the navigated group as compared to the control group. This was due to a 100% first-pass accuracy of drilling in the navigated group; in the control group a mean of 2.5 correction maneuvers per drilling were necessary. Additionally, the procedure was free of radiation in the navigated group, whereas 17.2 seconds of radiation exposure time were measured in the fluoroscopy-guided group. The developed Fluoro Free procedure is a promising and simplified approach to navigating different instruments as well as implants in relation to visually or tactilely placed pointers or objects without the need for radiation exposure or invasive fixation of a dynamic reference base in the bone.

    A new technique for vaginal intratubal insemination (VITI) and transvaginal gamete intra-Fallopian transfer (TV-GIFT) using endosonography has been developed. A total of 47 infertile couples were treated using a K-JITS 1000-1100 catheter (William Cook, Australia; Jansen Anderson Intratubal Transfer Set) introduced by Jansen and Anderson in Sydney, Australia, and endosonographic control with a Kretz Combison 310 echograph and a 5/7.5 MHz vaginal sectorial transducer. In 40 couples, the VITI technique was used, and in the other seven couples, TV-GIFT was used. Fifteen pregnancies (37.5%) were obtained in 63 VITI cycles (23.8% per treatment cycle) and three with TV-GIFT (42% per treatment cycle). A review is also presented of the migration--sedimentation technique used for management of male factor in an artificial insemination programme.

    To investigate the expression of vaginal Th1 and Th2 cytokines in rats with experimental vaginal candidiasis under different immune conditions, ICR murine vaginal candidiasis model was established and immno-suppressed murine models of vaginal cadidiasis were established in estrogen-treated mice. Non-estrogen-treated mice were used as controls. The mRNA level of Th1 (IL-2)/Th2 (IL-4, IL-10, TGF-beta1) cytokines in murine vaginal tissues was determined by RT-PCR. The cykotine in local tissues was increased to different extent under normal immune condition. IL-2 mRNA was increased during early stage of infection, while IL-10 was increased transiently during late stage of infection. TGF-beta1 production was found to be increased persistently. At same time, the expression of IL-2 mRNA was suppressed in immno-suppressed group, and the level of IL-4, IL-10, and TGF-beta1 were higher than the normal immunity group to different degree during infection. The high level of IL-2 mRNA during early stage of infection was associated with clearance of mucosal Candidia albicans (C. albicans), and its expression suppressed leading to decreased clearance of mucosal C. albican in immuno-suppression. The over-expression of IL-4 and IL-10 could significantly enhance the susceptibility to C. albicans infection in mice.

    The aim of this study was to explore the experiences of women who planned a vaginal breech birth. An online survey was developed consisting of questions regarding women's experiences surrounding planned vaginal breech birth. The survey was distributed between April 2014 and January 2015 to closed membership Facebook groups that had a consumer focus on vaginal breech birth. In total, 204 unique responses to the survey were obtained from women who had sought the option of a vaginal breech birth in a previous pregnancy. Most women (80.8%) stated that they were happy with the birth choices they made, and a significant proportion (89.4%) would attempt a vaginal breech birth in subsequent pregnancies. Less than half of women were formally referred to a clinician skilled in vaginal breech birth when their baby was diagnosed breech (41.8%), while the remainder sourced a clinician themselves. Half of the women felt supported by their care provider (56.7%) and less than half (42.3%) felt supported by family and friends. The women who responded to this international survey sought the option of a vaginal breech birth, were subsequently happy with this decision, and would attempt a vaginal breech birth in their next pregnancy. Access to vaginal breech birth is important for some women; however, this choice may be challenging to achieve. Consistent information and support from clinicians is important to assist decision-making. © 2016 Wiley Periodicals, Inc.

    We studied a locally applied vaginal preparation (vaginal suppositories) of ulinastatin (urinary trypsin inhibitor, UTI), designed to threatened premature delivery and maintain pregnancy. Witepsol S55 was chosen as the basic component of the vaginal suppositories based on the physical pharmaceutical characteristics of three kinds of hard fats. The average particle size of the UTI aqueous injection was approximately 70% as compared with that of the UTI lyophilized product, used as the base material for the preparation of UTI vaginal suppositories. We compared the physical pharmaceutical properties of UTI vaginal suppositories with water contents of 2.5%, 5.0%, and 7.5%, respectively. Preparation strength negatively correlated with the water content. The coefficient of viscosity positively correlated with the water content of the preparation. UTI vaginal suppositories with a water content of 5.0% had the highest average drug release rate on moment analysis. A comprehensive evaluation of the properties of UTI vaginal suppositories, including high strength due to disintegration resistance, the coefficient of viscosity and its influence on local retention, and drug release and its influence on the duration of effect, indicated that a 5.0% UTI aqueous solution for injection combined with Witepsol S55 as the base was the optimal formulation for the hospital preparation of vaginal suppositories.

    Ecological treatment of bacterial vaginosis and vaginitis with a Bio-three was studied, and the following results were obtained. 1. A total of 16 women with bacterial vaginosis and vaginitis were treated with intravaginal application of 2 g of Bio-three (E. faecalis T-110, C. butyricum TO-A, B. mesentericus TO-A, pH 6.9 +/- 0.3). The effect of the treatment was evaluated 3 days after administration by monitoring the vaginal discharge and bacteriological assessment. 2. The clinical improvement was evaluated and the decreases of vaginal discharge and vaginal redness were significant and vaginal pH was lowered significantly (5.29 +/- 0.24 vs. 4.31 +/- 0.37, p < 0.05). In the vaginal discharge 35 strains of bacteria were detected, but 3 days after administration, 16/30 strains of Gram-positive bacteria, and 2 strains of Gram-negative bacteria disappeared. As for the overall bacteriological effects, 7/16 cases were eradicated, 1 case was partly eradicated, 6 cases were replaced. These findings indicated that the Bio-three therapy was effective in both clinical and bacteriological responses.

    Radiation damage due to B+ ion implantation in p-type HgCdTe has been found to create Hg interstitials giving rise to n-type conversion. The implantation energies were kept at 50 and 100 keV with a dose of 1 X 1013 cm-2 each. The effect of implantation with ascending and descending orders of energies were found to be quite different from each other. Radiation enhanced diffusion is thought to be responsible for this anomaly.

    To study the long-term survival of dental implants placed in native or grafted bone in irradiated bone in subjects who had received radiation for head and neck cancer. A retrospective chart review was conducted for all patients who received dental implants following radiation treatment for head and neck cancer between May 1, 1987 and July 1, 2008. Only patients irradiated with a radiation dose of 50 Gy or greater and those who received dental implants in the irradiated field after head and neck radiation were included in the study. The associations between implant survival and patient/implant characteristics were estimated by fitting univariate marginal Cox proportional hazards models. A total of 48 patients who had prior head and neck radiation had 271 dental implants placed during May 1987-July 2008. There was no statistically significant difference between implant failure in native and grafted bone (P=0.76). Survival of implants in grafted bone was 82.3% and 98.1% in maxilla and mandible, respectively, after 3 years. Survival of implants in native bone in maxilla and mandible was 79.8% and 100%, respectively, after 3 years. For implants placed in the native bone, there was a higher likelihood of failure in the maxilla compared to the mandible and there was also a tendency for implants placed in the posterior region to fail compared to those placed in the anterior region. There was no significant difference in survival when implants were placed in native or grafted bone in irradiated head and neck cancer patients. For implants placed in native bone, survival was significantly influenced by the location of the implant (maxilla or mandible, anterior or posterior).

    Vaginal metastasis from organs other than the uterus is rare. Generally, patients with vaginal metastasis from colorectal cancer have a dismal prognosis. Although biopsy is the best method to make the diagnosis, massive bleeding may occur. On the other hand, liquid-based cytology (LBC) has the utility to perform immunocytochemistry on additional unstained slides: we can make a diagnosis with several immunocytochemical findings. A 67-year-old postmenopausal female presented to our hospital with vaginal bleeding. The patient had undergone colectomy because of her stage III sigmoid colon cancer 3 years earlier. The patient had also undergone hysterectomy for cervical cancer 30 years earlier. LBC from the vaginal stump revealed adenocarcinoma. Immunocytochemically, cancer cells were negative for cytokeratin 7 and positive for cytokeratin 20, which suggested metastasis from the sigmoid colon cancer; the diagnosis was made without a biopsy. When the patient has a metastatic lesion from colon adenocarcinoma, LBC with immunocytochemistry is useful in making a diagnosis. Copyright © 2012 S. Karger AG, Basel.

    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 thismore » 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

    Grafting material for vaginal reconstruction commonly includes the bowel, peritoneum, skin, and amniotic membrane. Bone marrow mesenchymal stem cells (MSCs) have the potential of multilineage differentiation into a variety of cells and have been widely explored in tissue engineering. In the current study, we examined whether MSCs could be differentiated to vaginal epithelial cells (VECs) upon co-culturing with VECs. We also examined whether Wnt/β-catenin signaling pathway is implicated in such differentiation. Co-culture of MSCs with VECs using a transwell insert system (with no direct contact) induced the expression of VECs marker AE1/AE3 in MSCs. MSCs combined with small intestinal submucosa (SIS) scaffold were implanted in place of the native vagina in rats to observe the implications for vaginal reconstruction in vivo. Anatomic repair of neovagina was assessed by histological staining for H/E and Masson's Trichrome. GSK-3β and β-catenin, main members of Wnt/β-catenin signaling pathway, in MSCs were increased upon co-culturing with VECs. Exposure of co-cultured MSCs to a Wnt/β-catenin signaling activator, lithium chloride (LiCl, 20 µM) increased phosphorylated GSK-3β and β-catenin and enhanced expression of AE1/AE3. In vivo-grafted cells displayed significant matrix infiltration and expressed epithelial markers in neovagina. These findings suggest that MSCs could acquire the phenotype of VECs when co-cultured with VECs, possibly via activation of Wnt/β-catenin signaling. MSCs provide an alternative cell source for potential use in vaginal tissue engineering. © 2015 International Federation for Cell Biology.

    Vaginal symptoms are a common chief complaint amongst women visiting outpatient clinics in rural Haiti. A systematic sample of 206 consecutive women over age 18 with gynaecological symptoms underwent gynaecologic examination and laboratory testing for chlamydia, gonorrhoea, syphilis, HIV infection, trichomoniasis, candidiasis, and bacterial vaginosis. 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 forChlamydia trachomatisin 5.4% (11/203), syphilis in 3.5% (7/202), HIV in 1.0% (2/200), andNeisseria gonorrhoeaein 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%). 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 programmes in young women should be considered. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    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.

    The pathophysiology and natural history of pelvic organ prolapse (POP) are poorly understood. Consequently, our approaches to treatment of POP are limited. Alterations in the extracellular matrix components of pelvic support ligaments and vaginal tissue, including collagen and elastin, have been associated with the development of POP in animals and women. Prior studies have shown the protease MMP-9, a key player of ECM degradation, is upregulated in vaginal tissues from both mice and women with POP. On the other hand, fibulin-5, an elastogenic organizer, has been found to inhibit MMP-9 in the vaginal wall. Hence, we hypothesized that prolonged release of fibulin-5 may delay progression of POP. To test the hypothesis, oligo (ethylene glycol)-based thermosensitive hydrogels were fabricated, characterized and then used to deliver fibulin-5 to the vaginal wall and inhibit MMP-9 activity. The results indicate that hydrogels are cell and tissue compatible. The hydrogels also prolong the ½ life of fibulin-5 in cultured vaginal fibroblasts and in the vaginal wall in vivo. Finally, fibulin-5-containing hydrogels resulted in incorporation of fibulin-5 into the vaginal matrix and inhibition of MMP-9 for several weeks after injection. These results support the idea of fibulin-5 releasing hydrogel being developed as a new treatment for POP. PMID:29073153

    Ascending bacterial infection is implicated in about 40-50% of preterm births. The human vaginal microbiota in most women is dominated by lactobacilli. In women whose vaginal microbiota is not lactobacilli-dominated anti-bacterial defence mechanisms are reduced. The enhanced proliferation of pathogenic bacteria plus degradation of the cervical barrier increase bacterial passage into the endometrium and amniotic cavity and trigger preterm myometrial contractions. Evaluation of protocols to detect the absence of lactobaciili dominance in pregnant women by self-measuring vaginal pH, coupled with measures to promote growth of lactobacilli are novel prevention strategies that may reduce the occurrence of preterm birth in low-resource areas. © 2014 Royal College of Obstetricians and Gynaecologists.

    Objectives: The optimal adjuvant therapy for International Federation of Gynecology and Obstetrics (FIGO) stage I papillary serous (UPSC) or clear cell (CC) endometrial cancer is unknown. We report on the largest single-institution experience using adjuvant high-dose-rate vaginal brachytherapy (VBT) for surgically staged women with FIGO stage I UPSC or CC endometrial cancer. Methods and Materials: From 1998-2011, 103 women with FIGO 2009 stage I UPSC (n=74), CC (n=21), or mixed UPSC/CC (n=8) endometrial cancer underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy followed by adjuvant high-dose-rate VBT. Nearly all patients (n=98, 95%) also underwent extended lymph node dissection of pelvic andmore » paraortic lymph nodes. All VBT was performed with a vaginal cylinder, treating to a dose of 2100 cGy in 3 fractions. Thirty-five patients (34%) also received adjuvant chemotherapy. Results: At a median follow-up time of 36 months (range, 1-146 months), 2 patients had experienced vaginal recurrence, and the 5-year Kaplan Meier estimate of vaginal recurrence was 3%. The rates of isolated pelvic recurrence, locoregional recurrence (vaginal + pelvic), and extrapelvic recurrence (including intraabdominal) were similarly low, with 5-year Kaplan-Meier estimates of 4%, 7%, and 10%, respectively. The estimated 5-year overall survival was 84%. On univariate analysis, delivery of chemotherapy did not affect recurrence or survival. Conclusions: VBT is effective at preventing vaginal relapse in women with surgical stage I UPSC or CC endometrial cancer. In this cohort of patients who underwent comprehensive surgical staging, the risk of isolated pelvic or extrapelvic relapse was low, implying that more extensive adjuvant radiation therapy is likely unnecessary.« less

    Young female patients with gynecologic complaints, including vaginal discharge, commonly seek care in the emergency department. Prepubertal vaginal discharges have various potential etiologies including nonspecific vulvovaginitis, infections, inflammatory or dermatologic processes, precocious puberty, malignancy, anatomical anomaly, trauma, sexual abuse, and foreign body. We present the case of a 4-year-old girl with vaginal odor and discharge secondary to a foreign body. The foreign body was part of a toy, the lower half of the patient's missing "Bratz" (MGA Entertainment) doll. Although it is well known that a vaginal foreign body can cause a vaginal discharge, the unusual nature of the foreign body in this case and the revealing radiograph made this a case of particular interest.

    Information on vaginal-related issues among Malaysian women is very limited. This study aimed to explore factors associated with preventive practices of vaginitis among Malaysian women. A cross-sectional computer-assisted telephone interview survey of a representative sample of multi-racial Malaysian women aged 18-50 years old was conducted from January to April 2014. Women from 1446 households responded to the survey and nearly one-third (32.1%) reported to have experienced vaginitis. In multivariate analyses, respondents in the urban locality were more likely to practice vaginitis prevention (OR = 1.40, 95% CI = 1.06-1.84) compared with those in the rural areas. Respondents who perceived low susceptibility to vaginitis were less likely to practice vaginitis prevention (OR = 0.72, 95% CI = 0.57-0.91) compared with responders who highly perceive susceptibility. Respondents who had no formal education were less likely to practice vaginitis prevention (OR = 0.16, 95% CI = 0.05-0.48) compared with those with tertiary education. This study showed that comprehensive education and health programmes need to focus on women with a low educational level, living in rural areas and women with low perceived susceptibility to vaginitis. Impact statement What is already known on this subject? Little is known about vaginitis issues among women in Malaysia. This study provides information regarding vaginitis among Malaysian women by looking at the factors associated with prevention practices. What do the results of this study add? From our study, factors associated with prevention practices were found to be educational level, locality, and perceived susceptibility of vaginitis. Those who perform fewer vaginitis prevention practices were women with a low educational level and those who live in rural areas. From the Health Belief Model, women with a low perceived susceptibility of vaginitis were less likely to carry out vaginitis prevention practices. What are

    Vaginal prolapse is the protrusion of edematous vaginal tissue into and through the opening of the vulva occurring during the pro-oestrus and oestrus stages of the sexual cycle. True vaginal prolapse may occur near parturition, as the concentration of serum progesterone declines and the concentration of serum oestrogen increases. In a bitch, true vaginal prolapse is a very rare condition. This case report describes an 18-month-old crossbreed bitch, weighing 40 kg presented with type III vaginal prolapse. The patient had developed vaginal prolapse after receiving oestrogen in order to oestrus induction. Subsequent to unsuccessful attempts for repositioning, ovariohysterectomy (OHE), circumferential excision of the prolapsed tissue and finally vulvoplasty were performed. There was no evidence of recurrence of the prolapse during 30 days after surgery. This case report describes type III vaginal prolapse as an unusual side effect of oestrus induction hormonal therapy in the bitch.

  8. The Vaginal Microbiota and Urinary Tract Infection.

    2016-12-01

    The vagina is a key anatomical site in the pathogenesis of urinary tract infection (UTI) in women, serving as a potential reservoir for infecting bacteria and a site at which interventions may decrease the risk of UTI. The vaginal microbiota is a dynamic and often critical factor in this pathogenic interplay, because changes in the characteristics of the vaginal microbiota resulting in the loss of normally protective Lactobacillus spp. increase the risk of UTI. These alterations may result from the influence of estrogen deficiency, antimicrobial therapy, contraceptives, or other causes. Interventions to reduce adverse effects on the vaginal microbiota and/or to restore protective lactobacilli may reduce the risks of UTI.

    It was shown that IL-1β, IL-8, and IL-6 in concentrations similar to those in the vagina of healthy women stimulated the growth of normal microflora (Lactobacillus spp.) and suppressed the growth and biofilm production by S. aureus and E. coli. On the contrary, these cytokines in higher concentrations typical of vaginal dysbiosis suppressed normal microflora and stimulated the growth of opportunistic microorganisms. TGF-β1 in both doses produced a stimulating effects on study vaginal microsymbionts. It is hypothesized that pro-inflammatory cytokines serve as the molecules of interspecies communication coordinating the interactions of all components of the vaginal symbiotic system.

    2012-01-01

    Since 2004, use of synthetic mesh has increased in vaginal surgery for the treatment of pelvic organ prolapse. However, concerns exist about the safety and efficacy of transvaginally placed mesh. Based on the currently available limited data, although many patients undergoing mesh-augmented vaginal repairs heal well without problems, there seems to be a small but significant group of patients who experience permanent and life-altering sequelae, including pain and dyspareunia, from the use of vaginal mesh. The American College of Obstetricians and Gynecologists and the American Urogynecologic Society provide background information on the use of vaginally placed mesh for the treatment of pelvic organ prolapse and offer recommendations for practice.

    Recently, vaginal douching has been associated with many health risks in women. The aim of this study was to analyze the effect of commercial douche products against various vaginal microorganisms, including lactobacilli. Seven commercial douches were tested against eight Lactobacillus clinical isolates and three type strains from the American Type Culture Collection. BV-associated bacteria included six strains of five genera: Gardnerella, Mobiluncus, Mycoplasma, Peptostreptococcus, and Ureaplasma. Two isolates of group B Streptococcus, and three species of Candida were also tested. The minimal inhibition concentrations and minimal contact times for these products against vaginal microorganisms were determined in broth cultures. Four antiseptic-containing douche products showed a strong inhibitory effect against all vaginal microorganisms tested with a short contact time (less than 1 min). Three vinegar-containing douche products selectively inhibited vaginal pathogens associated with bacterial vaginosis, group B streptococcal vaginitis, and candidiasis, but not lactobacilli. The antimicrobial effects of the commercial douche products varied among different brands and microbial species tested. PMID:10805365

    A vesicovaginal fistula with vagina obstruction associated with vaginal calculi is an extremely rare medical condition. We report a giant primary vaginal calculus resulting from vesicovaginal fistula with partial vaginal outlet obstruction secondary to perineum trauma and surgery in a 12-year-old girl. Episiotomy was performed and the adhesive labia minora was split. After the removal of a giant calculus in the vagina, approximately 8 cm in diameter, the fistula tract was completely excised, followed by the repair of the vesicovagina fistula and the vagina. The patient was symptom-free at 6-month follow-up examination. Copyright © 2011 Elsevier Inc. All rights reserved.

    Bacterial vaginosis increases the susceptibility to sexually transmitted infections and negatively affects women's reproductive health. To investigate host-vaginal microbiota interactions and the impact on immune barrier function, we colonized 3-dimensional (3-D) human vaginal epithelial cells with 2 predominant species of vaginal microbiota (Lactobacillus iners and Lactobacillus crispatus) or 2 prevalent bacteria associated with bacterial vaginosis (Atopobium vaginae and Prevotella bivia). Colonization of 3-D vaginal epithelial cell aggregates with vaginal microbiota was observed with direct attachment to host cell surface with no cytotoxicity. A. vaginae infection yielded increased expression membrane-associated mucins and evoked a robust proinflammatory, immune response in 3-D vaginal epithelial cells (ie, expression of CCL20, hBD-2, interleukin 1β, interleukin 6, interleukin 8, and tumor necrosis factor α) that can negatively affect barrier function. However, P. bivia and L. crispatus did not significantly upregulate pattern-recognition receptor-signaling, mucin expression, antimicrobial peptides/defensins, or proinflammatory cytokines in 3-D vaginal epithelial cell aggregates. Notably, L. iners induced pattern-recognition receptor-signaling activity, but no change was observed in mucin expression or secretion of interleukin 6 and interleukin 8. We identified unique species-specific immune signatures from vaginal epithelial cells elicited by colonization with commensal and bacterial vaginosis-associated bacteria. A. vaginae elicited a signature that is consistent with significant disruption of immune barrier properties, potentially resulting in enhanced susceptibility to sexually transmitted infections during bacterial vaginosis. © The Author 2014.

    Vaginal discharge in children may result from a variety of causes. A long-standing intra-vaginal foreign body can pose both diagnostic and therapeutic challenges in children. Treatment failure may occur because of alteration of the normal vaginal flora. A 6-year-old girl, who lived with her parents, presented with a foul-smelling, blood-stained vaginal discharge as well as dysuria for 2 years. There was no history of sexual abuse. Initial evaluation that excluded gynecologic examination revealed lower abdominal tenderness. Vaginal swab and urine cultures yielded Staphylococcus aureus sensitive to ceftriaxone only. She was commenced on this antibiotic for 2 weeks, but the discharge persisted, necessitating referral to the gynecologist. Examination under anesthesia by the gynecologist revealed shreds of toilet tissue paper extracted from the vagina and slight excoriations on the wall of the vagina. Vaginal foreign body can present with diverse symptoms. It should be considered in any young female patient presenting with recurrent or persistent vaginal discharge. PMID:23634340

    2012-12-01

    Research indicates that (i) women's orgasm during penile-vaginal intercourse (PVI) is influenced by fitness-related male partner characteristics, (ii) penis size is important for many women, and (iii) preference for a longer penis is associated with greater vaginal orgasm consistency (triggered by PVI without concurrent clitoral masturbation). To test the hypothesis that vaginal orgasm frequency is associated with women's reporting that a longer than average penis is more likely to provoke their PVI orgasm. Three hundred twenty-three women reported in an online survey their past month frequency of various sexual behaviors (including PVI, vaginal orgasm, and clitoral orgasm), the effects of a longer than average penis on likelihood of orgasm from PVI, and the importance they attributed to PVI and to noncoital sex. Univariate analyses of covariance with dependent variables being frequencies of various sexual behaviors and types of orgasm and with independent variable being women reporting vs. not reporting that a longer than average penis is important for their orgasm from PVI. Likelihood of orgasm with a longer penis was related to greater vaginal orgasm frequency but unrelated to frequencies of other sexual behaviors, including clitoral orgasm. In binary logistic regression, likelihood of orgasm with a longer penis was related to greater importance attributed to PVI and lesser importance attributed to noncoital sex. Women who prefer deeper penile-vaginal stimulation are more likely to have vaginal orgasm, consistent with vaginal orgasm evolving as part of a female mate choice system favoring somewhat larger than average penises. Future research could extend the findings by overcoming limitations related to more precise measurement of penis length (to the pubis and pressed close to the pubic bone) and girth, and large representative samples. Future experimental research might assess to what extent different penis sizes influence women's satisfaction and likelihood

Teaching and research hospital, a tertiary center. Fifty-two women with POP-Q stage 0 or 1 uterine prolapse were randomized into 2 groups using vertical (n = 26) or horizontal (n = 26) vaginal cuff closure. All patients underwent vaginal hysterectomy. Vagina length in the 2 groups was compared preoperatively, immediately after surgery, and at 6 weeks postoperatively. Mean (SD) preoperative vagina length in the horizontal and vertical groups was similar (7.87 [0.92] cm vs 7.99 [0.78] cm; p = .41). Immediately postoperatively, the vagina was significantly shorter in the horizontal group than in the vertical group (6.61 [0.89] cm vs 7.51 [0.74] cm; p < .001). At 6 weeks postoperatively, the vagina was still significantly shorter in the horizontal group (6.55 [0.89] cm vs 7.42 (0.73) cm; p < .001). The mean difference in vagina length before and after surgery was also significantly higher in the horizontal group than in the vertical group (-1.26 [0.12] cm vs 0.49 [0.11] cm; p < .001). Vertical cuff closure during vaginal hysterectomy seems to preserve vagina length better than does horizontal cuff closure. Copyright © 2014 AAGL. Published by Elsevier Inc. All rights reserved.

  18. Effects of Reproductive Hormones on Experimental Vaginal Candidiasis

    PubMed Central

    Fidel, Paul L.; Cutright, Jessica; Steele, Chad

    2000-01-01

    Vulvovaginal candidiasis (VVC) is an opportunistic mucosal infection caused by Candida albicans that affects large numbers of otherwise healthy women of childbearing age. Acute episodes of VVC often occur during pregnancy and during the luteal phase of the menstrual cycle, when levels of progesterone and estrogen are elevated. Although estrogen-dependent experimental rodent models of C. albicans vaginal infection are used for many applications, the role of reproductive hormones and/or their limits in the acquisition of vaginal candidiasis remain unclear. This study examined the effects of estrogen and progesterone on several aspects of an experimental infection together with relative cell-mediated immune responses. Results showed that while decreasing estrogen concentrations eventually influenced infection-induced vaginal titers of C. albicans and rates of infection in inoculated animals, the experimental infection could not be achieved in mice treated with various concentrations of progesterone alone. Furthermore, progesterone had no effect on (i) the induction and persistence of the infection in the presence of estrogen, (ii) delayed-type hypersensitivity in primary-infected mice, or (iii) the partial protection from a secondary vaginal infection under pseudoestrus conditions. Other results with estrogen showed that a persistent infection could be established with a wide range of C. albicans inocula under supraphysiologic and near-physiologic (at estrus) concentrations of estrogen and that vaginal fungus titers or rates of infection were similar if pseudoestrus was initiated several days before or after inoculation. However, the pseudoestrus state had to be maintained for the infection to persist. Finally, estrogen was found to reduce the ability of vaginal epithelial cells to inhibit the growth of C. albicans. These results suggest that estrogen, but not progesterone, is an important factor in hormone-associated susceptibility to C. albicans vaginitis. PMID

    Vaginal infections are extremely prevalent, particularly among women of reproductive age. Although they do not result in high mortality rates, these infections are associated with high levels of anxiety and reduction of quality of life. In most cases, topical treatment of vaginal infections has been shown to be at least as effective as oral treatment, resulting in higher local drug concentrations, with fewer drug interactions and adverse effects. Furthermore, the emergence of microbial resistance to chemotherapeutics and the difficulties in managing infection recurrences sustain the need for more effective local treatments. However, conventional dosage forms have been associated with low retention in the vagina and discomfort. Formulation strategies such as the development of bioadhesive, thermogelling systems and microtechnological or nanotechnological approaches have been proposed to improve delivery of traditional drugs, and other treatment modalities such as new drugs, plant extracts, and probiotics are being studied. This article reviews the recent strategies studied to improve the treatment and prevention of the commonest vaginal infections-namely, vaginal bacteriosis, aerobic vaginitis, vulvovaginal candidosis, and trichomoniasis-through the intravaginal route.

    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?

    Structured Abstract Study Objective To explore adolescent’s perceptions of vaginal health, practices, and vaginally-placed products. Design Semi-structured interviews were audio-recorded and transcribed until achieving theoretical saturation. Setting Adolescent medicine clinics in NYC. Participants Adolescent females (n = 22) who were sexually experienced, predominately Hispanic (73%) with a mean age of 17.7 years (range 15–20 years). Interventions None Main Outcome Measures Interviews assessed perspectives on vaginal health, specific vaginal hygiene practices and attitudes about vaginally-placed products (contraceptive rings, intrauterine devices (IUDs), and proposed multi-purpose technologies (MPTs) administered as ring or gel). The interviews were transcribed and coded for relevant themes. Results Overlapping themes included young women’s view of their vagina as a space that needed to be healthy for sexual partners and future fertility. The vagina could not be presumed to be healthy and conversations about vaginal health were limited to only include specific individuals. All reported a variety of practices to maintain their vaginal health, including showering 1 to 5 times a day and using soaps specifically for the vagina. Attitudes about vaginally-placed products revealed concerns about the sensory experience of having a product in the vagina, safety concerns and interest in the product’s objective (prevention of pregnancy or infection). Conclusions Adolescents have very specific views and practices about their vaginas. Clinicians should initiate conversations about vaginal health and hygiene with adolescents and focus on the normalcy of the vagina. Development of vaginally-placed products should focus on the sensory experience, safety and purpose of the product. PMID:27133374

A prospective study. Gynecology-Obstetrics Outpatient Department LEVRET Ltd., AescuLab Ltd., Laboratory of Microbiology, Prague. 50 women with vaginal discomfort, causes of which had not been clarified by gynecological examination, determination of pH and the amine test, were examined by vaginal smears using microscopy. The results were evaluated in relation to aerobic vaginitis in a pure form or in combination with other nosological units. The authors also evaluated results of therapy by oral nifuratel (Macmiror tbl) 3 x 200 mg daily and a vaginal combined preparation containing nifuratel 500 mg + nystatin 200 kIU (Macmiror complex 500 glo vag) for the period of 7 days. In 50 women candida was demonstrated 24 times, presence of key cells 11 times, lactobacillus nine times with more than 50 in the field, six women were affected by aerobic vaginitis. In all these cases the pH was 4.8 or higher, leukocytes were significantly represented in all cases (> 15 in the field), as well as gram-negative bacteria and/or cocci (> 30 in the field), indicating a combined picture of mycosis, anaerobic vaginosis or lactobacillosis with aerobic vaginitis. The therapy was successful in all cases, the relapse of complaints during one month occurred in three cases. Aerobic vaginitis in a pure form or with anaerobic vaginosis, mycosis or lactobacillosis is frequently concealed under clinically uncertain pictures of vulvo-vaginal discomfort. The therapy by a combination of nifurated 3 x 200 mg orally together with the combined vaginal preparation nifuratel 500 mg + nystatin 200 kIU for the period of 7 days exerts high effect and a low number of relapses.

    The safety of metallic spinal implants in magnetic resonance imaging (MRI) performed using ultrahigh fields has not been established. Hence, we examined whether the displacement forces caused by a static magnetic field and the heating induced by radiofrequency radiation are substantial for spinal implants in a 7 T field. We investigated spinal rods of various lengths and materials, a screw, and a cross-linking bridge in accordance with the American Society for Testing and Materials guidelines. The displacement forces of the metallic implants in static 7 T and 3 T static magnetic fields were measured and compared. The temperature changes of the implants during 15-min-long fast spin-echo and balanced gradient-echo image acquisition sequences were measured in the 7 T field. The deflection angles of the metallic spinal materials in the 7 T field were 5.0-21.0° [median: 6.7°], significantly larger than those in the 3 T field (1.0-6.3° [2.2°]). Among the metallic rods, the cobalt-chrome rods had significantly larger deflection angles (17.8-21.0° [19.8°]) than the pure titanium and titanium alloy rods (5.0-7.7° [6.2°]). The temperature changes of the implants, including the cross-linked rods, were 0.7-1.0°C [0.8°C] and 0.6-1.0°C [0.7°C] during the fast spin-echo and balanced gradient-echo sequences, respectively; these changes were slightly larger than those of the controls (0.4-1.1°C [0.5°C] and 0.3-0.9°C [0.6°C], respectively). All of the metallic spinal implants exhibited small displacement forces and minimal heating, indicating that MRI examinations using 7 T fields may be performed safely on patients with these implants. © 2016 The Authors.

    This study was undertaken to evaluate a diagnostic panty liner (VI-SENSE) (Common Sense, Caesarea, Israel) developed to facilitate diagnosis of vaginal infections by detecting disordered acidity level. Five hundred sixteen women with vulvovaginal symptoms were enrolled. Final clinical diagnosis included Amsel criteria, Gram stain analysis, pH determination, and Trichomonas vaginalis and Candida culture. VI-SENSE strip color status estimated by patients was compared with clinical diagnosis and pH measurement by using nitrazine paper. Statistical analysis included sensitivity and specificity calculations. The VI-SENSE test was positive in 226 of 249 patients (90.8%) with bacterial vaginosis or trichomoniasis. Nitrazine pH paper revealed elevated pH in 165 (66.5%) and the amine test was positive in 160 (64.3%) patients. The VI-SENSE test was negative in 217 of 267 patients (81.3%) without trichomoniasis or bacterial vaginosis. The VI-SENSE was positive in 85 of 92 women (92%), with mixed vaginal infection including Candida and bacterial vaginosis or trichomoniasis. Amine test, nitrazine pH paper and physician diagnosis relying only on speculum examination were inferior and positive in only 65 (70%), 59 (64%), and 66 (72%) patients, respectively. The VI-SENSE test was found to be superior to traditional individual tests in facilitating preliminary diagnosis of vaginal infections.

These alterations may result from the influence of estrogen deficiency, antimicrobial therapy, contraceptives, or other causes. Interventions to reduce adverse effects on the vaginal microbiota and/or to restore protective lactobacilli may reduce the risks of UTI. PMID:28087949

    The polypropylene mesh (PPM) is used in many surgical interventions because of its good incorporation and accessibility. However, potential mesh-related complications are common. Platelet-rich plasma (PRP) improves the healing of wounds and is inexpensive. Thus, the purpose of this study was to analyze the effect of the PRP-gel coating of a PPM on inflammation, production of collagen, and smooth muscle in the rabbit vagina. The intervention consisted of a 1.5cm incision and divulsion of the vaginal mucosa for the implantation of a PRP-coated PPM. The PRP-coated mesh was implanted in 15 rabbits, and in the second group, the same implant was used without the PRP coating. In the sham group, the intervention consisted of the incision, divulsion, and suture. The rabbits were euthanized at 7, 30 and 90 days, and full-thickness sagittal sections of the posterior vaginal wall and rectum were scored. The inflammatory infiltrate was evaluated using hematoxylin and eosin staining. The Sirius Red stain was used to examine deposition of collagen I and III, and Masson's trichrome staining was used to visualize the smooth muscle. The group with PRP-coated meshes had a lower inflammatory infiltrate count at 30 days. Deposition of collagen III increased with the use of PRP-coating at 90 days. The area of inflammatory infiltrate was significantly increased in the group without the PRP-coated mesh at 30 days but not in the group with the PRPcoated mesh, indicating a less intense inflammatory response. In addition, a significant increase in collagen III occurred at 90 days. Copyright® by the International Brazilian Journal of Urology.

    Vaginal atrophy is a frequent complaint of postmenopausal women; symptoms include vaginal dryness, itching, discomfort and painful intercourse. Systemic treatment for these symptoms in the form of oral hormone replacement therapy is not always necessary. An alternative choice is oestrogenic preparations administered vaginally (in the form of creams, pessaries, tablets and the estradiol releasing ring). The objective of this review is to compare the effectiveness, safety and acceptability of oestrogenic preparations for women who suffer from vaginal atrophy. We searched the Cochrane Menstrual Disorders and Subfertility Group register of trials (searched January 2003), The Cochrane Library (Issue 2, 2003), MEDLINE (1966-January 2003), EMBASE (1980-January 2003), Current Contents (1993-January 2003), Biological Abstracts (1969-2002), Social Sciences Index (1980-January 2003), PsycINFO (1972-February 2003), CINAHL (1982-January 2003) and reference list of articles. We also contacted manufacturers and researchers in the field. The inclusion criteria were randomised comparisons of oestrogenic preparations administered intravaginally in postmenopausal women for the treatment of symptoms resulting from vaginal atrophy or vaginitis. Twenty nine trials were identified, of these 13 were excluded. Trials were assessed for quality and two reviewers extracted data independently. Ratios for dichotomous and means for continuous outcomes were estimated. Outcomes analysed were included under the headings of efficacy, safety and acceptability. Sixteen trials with 2129 women were included in this review. The overall quality of the studies was good, although not all trials measured the same outcomes. All trials measured efficacy with various outcome measures. When comparing efficacy of oestrogenic preparations (in the form of creams, pessaries, tablets and the estradiol releasing vaginal ring) with each other in relieving the symptoms of vaginal atrophy, results indicated significant

    After reading this article, participants should be able to: 1. Understand the evidence regarding the timing of expander/implant breast reconstruction in the setting of radiation therapy. 2. Discuss the implications of a patient's risk factors for possible outcomes and complications of expander/implant breast reconstruction. 3. Implement proper prophylactic antibiotic protocols. 4. Use the guidelines to improve their own clinical outcomes and reduce complications. In March of 2013, the Executive Committee of the American Society of Plastic Surgeons approved an evidence-based guideline on breast reconstruction with expanders and implants, as developed by a guideline-specific work group commissioned by the society's Health Policy Committee. The guideline addresses ten clinical questions: patient education, immediate versus delayed reconstruction, risk factors, radiation therapy, chemotherapy, hormonal therapy, antibiotic prophylaxis, acellular dermal matrix, monitoring for cancer recurrence, and oncologic outcomes associated with implant-based reconstruction. The evidence indicates that patients undergoing mastectomy should be offered a preoperative referral to a plastic surgeon. Evidence varies regarding the association between postoperative complications and timing of postmastectomy expander/implant breast reconstruction. Evidence is limited regarding the optimal timing of expand/implant reconstruction in the setting of radiation therapy but suggests that irradiation to the expander or implant is associated with an increased risk of postoperative complications. Evidence also varies regarding the association between acellular dermal matrix and surgical complications in the setting of postmastectomy expander/implant reconstruction. Data support the use of an appropriate preoperative antibiotic, but antibiotics should be discontinued within 24 hours of the procedure, unless a surgical drain is present. Furthermore, postmastectomy expander/implant breast reconstruction

    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.

    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.

    OBJECTIVE To evaluate recent advances in our understanding of the clinical relevance, diagnosis, and treatment of vaginal infections, and to determine an efficient and effective method of evaluating this clinical problem in the outpatient setting. DATA SOURCES Relevant papers on vaginitis limited to the English language obtained through a MEDLINE search for the years 1985 to 1997 were reviewed. DATA SYNTHESIS Techniques that enable the identification of the various strains of candida have helped lead to a better understanding of the mechanisms of recurrent candida infection. From this information a rationale for the treatment of recurrent disease can be developed. Bacterial vaginosis has been associated with complications, including upper genital tract infection, preterm delivery, and wound infection. Women undergoing pelvic surgery, procedures in pregnancy, or pregnant women at risk of preterm delivery should be evaluated for bacterial vaginosis to decrease the rate of complications associated with this condition. New, more standardized criteria for the diagnosis of bacterial vaginosis may improve diagnostic consistency among clinicians and comparability of study results. Use of topical therapies in the treatment of bacterial vaginosis are effective and associated with fewer side effects than systemic medication. Trichomonas vaginalis, although decreasing in incidence, has been associated with upper genital tract infection. Therapy of T. vaginalis infection has been complicated by an increasing incidence of resistance to metronidazole. CONCLUSIONS Vaginitis is a common medical problem in women that is associated with significant morbidity and previously unrecognized complications. Research in recent years has improved diagnostic tools as well as treatment modalities for all forms of vaginitis. PMID:9613891

    1972-07-01

    A guest faculty discussed the management of patients with vaginal infections. It was agreed that correct diagnosis is necessary before therapy. Diagnosis can be accomplished by a microscopic examination in 90% of the cases. The cytologic smear is also very important. Specific culture media may be useful for troublesome cases, for instance, blood agar fo Haemophilus vaginalis, Trichocel medium for Trichiomonas vaginalis, Neckerson's medium for candidal species and Thayer-Martin for Neisseria gonorrhoeae. Patient history is important since some infections tend to occur in certain patients such as candidiasis in patients with diabetes mellitus, patients who are pregnant or are taking broad spectrum antibiotics, estrogen or contraceptive pills. The pH of vaginal secretions may also be helpful in making the diagnosis. It was suggested that the term "nonspecific" vaginitis is a misnomer and is used to conceal ignorance. Others felt that such agents as soap, vaginal deodorant spray, and clothing may be causatives. The term "psychogenic leukorrhea" was discussed with varying conclusions. Routine treatment for each form of vaginitis was outlines and treatment for recurrent, persistent trichomoniasis and moniliasis was given. It was agreed that douching will not cure vaginitis but may be useful in removing excessive secretion. It is not recommended for routine hygeine but is acceptable following menstruation or intercourse.

    In 2 studies with 10 women each, vaginal self-stimulation significantly increased the threshold to detect and tolerate painful finger compression, but did not significantly affect the threshold to detect innocuous tactile stimulation. The vaginal self-stimulation was applied with a specially designed pressure transducer assembly to produce a report of pressure or pleasure. In the first study, 6 of the women perceived the vaginal stimulation as producing pleasure. During that condition, the pain tolerance threshold increased significantly by 36.8% and the pain detection threshold increased significantly by 53%. A second study utilized other types of stimuli. Vaginal self-stimulation perceived as pressure significantly increased the pain tolerance threshold by 40.3% and the pain detection threshold by 47.4%. In the second study, when the vaginal stimulation was self-applied in a manner that produced orgasm, the pain tolerance threshold and pain detection threshold increased significantly by 74.6% and 106.7% respectively, while the tactile threshold remained unaffected. A variety of control conditions, including various types of distraction, did not significantly elevate pain or tactile thresholds. We conclude that in women, vaginal self-stimulation decreases pain sensitivity, but does not affect tactile sensitivity. This effect is apparently not due to painful or non-painful distraction.

    The protective roles of different lymphocyte subsets were investigated in a rat vaginal candidiasis model by adoptive transfer of vaginal lymphocytes (VL) or sorted, purified CD3+ T cells, CD4+ or CD8+ T cells, or CD3− CD5+ B cells from the vaginas of naïve or immune rats following three rounds of Candida albicans infection. The adoptive transfer of total VL from nonimmune animals did not alter the course of vaginal candidiasis of the recipient rats. In contrast, the animals receiving total VL or CD3+ T cells from immune rats showed a highly significant acceleration of fungus clearance compared with animals which received nonimmune VL. The animals with vaginal CD3− CD5+ B cells transferred from immune rats also had fewer Candida CFU than the controls, but fungal clearance was significantly retarded with respect to the animals administered immune T cells. Sorted, purified CD4+ and CD8+ vaginal T cells from immune rats were also adoptively transferred to naïve animals. Although both populations were seen to accelerate the clearance of the fungus from the vagina, CD4+ T cells were much more effective than CD8+ T cells. Overall, there was no difference between the antifungal effects of immune vaginal CD4+ T cells and those achievable with the transfer of whole, immune VL. Histological observations of the vaginal tissues of rats with adoptively transferred immune T cells demonstrated a remarkable accumulation of lymphocytes in the subepithelial lamina propria and also infiltrating the mucosal epithelium. These results strongly suggest that distinct vaginal lymphocyte subsets participate in the adaptive anti-Candida immunity at the vaginal level, with the vaginal CD4+ T cells probably playing a major role.

    In the non-industrialized countries of Africa and Asia obstetric fistulas are more frequently caused by prolonged labour, whereas in countries with developed healthcare systems they are generally the result of complications of gynaecological surgery or, rarely, benign pathologies like inflammation or foreign bodies. A 22-year-old woman was brought to the gynaecology clinic because of foul-smelling vaginal discharge. On pelvic examination a ring-like foreign body was impacted between the anterior and posterior vaginal wall. MRI scan confirmed the presence of a cylindrical foreign body in the vagina and the patient revealed that she had 'involuntarily' inserted a plastic bubble bath cap into the vagina. At surgery removal of the cap was difficult and at the end of the manoeuver evidence of a huge urethro-vesico-vaginal fistula occurred. The patient was discharged with bilateral ureteral stents and suprapubic catheter. After 3 months we performed an end-to-end anastomotic urethroplasty to repair the urethral avulsion and restored the bladder/trigonal and vaginal/cervical defects with 3 layers of sutures; 3 months later the patient had no complaints. Complex genital fistulas represent an extremely debilitating morbidity. In our case, a vaginal approach was successful, but the choice between an abdominal or vaginal approach depends on the surgeon's experience and training. © 2015 S. Karger AG, Basel.

  18. Use of porcine vaginal tissue ex-vivo to model environmental effects on vaginal mucosa to toxic shock syndrome toxin-1

    Davis, Catherine C.; Baccam, Mekhine; Mantz, Mary J.

    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 determinedmore » 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

    Despite decades of attempts to link infectious agents to preterm birth, an exact causative microbe or community of microbes remains elusive. Nonculture 16S ribosomal RNA gene sequencing suggests important racial differences and pregnancy specific changes in the vaginal microbial communities. A recent study examining the association of the vaginal microbiome and preterm birth documented important findings but was performed in a predominantly white cohort. Given the important racial differences in bacterial communities within the vagina as well as persistent racial disparities in preterm birth, it is important to examine cohorts with varied demographic compositions. To characterize vaginal microbial community characteristics in a large, predominantly African-American, longitudinal cohort of pregnant women and test whether particular vaginal microbial community characteristics are associated with the risk for subsequent preterm birth. This is a nested case-control study within a prospective cohort study of women with singleton pregnancies, not on supplemental progesterone, and without cervical cerclage in situ. Serial mid-vaginal swabs were obtained by speculum exam at their routine prenatal visits. Sequencing of the V1V3 region of the 16S rRNA gene was performed on the Roche 454 platform. Alpha diversity community characteristics including richness, Shannon diversity, and evenness as well as beta diversity metrics including Bray Curtis Dissimilarity and specific taxon abundance were compared longitudinally in women who delivered preterm to those who delivered at term. A total of 77 subjects contributed 149 vaginal swabs longitudinally across pregnancy. Participants were predominantly African-American (69%) and had a preterm birth rate of 31%. In subjects with subsequent term delivery, the vaginal microbiome demonstrated stable community richness and Shannon diversity, whereas subjects with subsequent preterm delivery had significantly decreased vaginal richness

    Streptococcus agalactiae (group B Streptococcus [GBS]) is an important neonatal pathogen and emerging cause of disease in adults. The major risk factor for neonatal disease is maternal vaginal colonization. However, little is known about the relationship between GBS and vaginal microbiota. Vaginal lavage samples from nonpregnant women were tested for GBS, and amplicon-based sequencing targeting the 16S ribosomal RNA V3-V4 region was performed. Four hundred twenty-eight of 432 samples met the high-quality read threshold. There was no relationship between GBS carriage and demographic characteristics, α-diversity, or overall vaginal microbiota community state type (CST). Within the non-Lactobacillus-dominant CST IV, GBS positive status was significantly more prevalent in CST IV-A than CST IV-B. Significant clustering by GBS status was noted on principal coordinates analysis, and 18 individual taxa were found to be significantly associated with GBS carriage by linear discriminant analysis. After adjusting for race/ethnicity, 4 taxa were positively associated with GBS, and 6 were negatively associated. Vaginal microbiota CST and α-diversity are not related to GBS status. However, specific microbial taxa are associated with colonization of this important human pathogen, highlighting a potential role for the microbiota in promotion or inhibition of GBS colonization. © The Author 2017.

    Background & objectives: Bacterial vaginosis (BV) is highly prevalent among women in reproductive age group. Little information exists on routine vaginal pH measurement in women with BV. We undertook this study to assess the utility of vaginal pH determination for initial evaluation of bacterial vaginosis. Methods: In this cross-sectional study vaginal swabs were collected from women with complaints of white discharge, back ache and pain abdomen attending a government hospital and a community health clinic, and subjected to vaginal pH determination, Gram stain, wet mount and whiff test. Nugent score and Amsel criteria were used for BV confirmation. Results: Of the 270 women included in the analysis, 154 had BV based on Nugents’ score. The mean vaginal pH in women with BV measured by pH strips and pH glove was 5 and 4.9, respectively. The vaginal pH was significantly higher in women with BV. Vaginal discharge was prevalent in 84.8 per cent women, however, only 56.8 per cent of these actually had BV by Nugent score (NS). Presence of clue cells and positive whiff test were significant for BV. Vaginal pH >4.5 by pH strips and pH Glove had a sensitivity of 72 and 79 per cent and specificity of 60 and 53 per cent, respectively to detect BV. Among the combination criteria, clue cells and glove pH >4.5 had highest sensitivity and specificity to detect BV. Interpretation & conclusions: Vaginal pH determination is relatively sensitive, but less specific in detecting women with BV. Inclusion of whiff test along with pH test reduced the sensitivity, but improved specificity. Both, the pH strip and pH glove are equally suitable for screening women with BV on outpatient basis.

Female adolescents (N = 22) who were sexually experienced, predominately Hispanic (73%, n = 16) with a mean age of 17.7 years (range, 15-20 years). None. Interviews were used to assess perspectives on vaginal health, specific vaginal hygiene practices, and attitudes about vaginally-placed products (contraceptive rings, intrauterine devices), and proposed multipurpose technologies administered as ring or gel). The interviews were transcribed and coded for relevant themes. Overlapping themes included young women's view of their vagina as a space that needed to be healthy for sexual partners and future fertility. The vagina could not be presumed to be healthy and conversations about vaginal health were limited to include only specific individuals. All reported a variety of practices to maintain their vaginal health, including showering 1-5 times a day and using soaps specifically for the vagina. Attitudes about vaginally-placed products revealed concerns about the sensory experience of having a product in the vagina, safety concerns and interest in the product's objective (prevention of pregnancy or infection). Adolescents have very specific views and practices about their vaginas. Clinicians should initiate conversations about vaginal health and hygiene with adolescents and focus on the normalcy of the vagina. Development of vaginally-placed products should focus on the sensory experience, safety, and purpose of the product. Copyright © 2016 North American Society for Pediatric and Adolescent Gynecology.

    To study the role of vaginal flora and pH in the pathogenesis of Trichomonas vaginalis, an intravaginal mouse model of infection was established. By employing this model, the vaginal flora and pH of mice could be monitored for changes caused by the parasite. As a baseline, the endemic vaginal flora of BALB/c mice was examined first and found to consist mainly of Staphylococcus aureus and Enterococcus species (32-76%). Lactobacilli and enteric bacilli were moderate (16-32%) in their frequency of isolation, and the prevalence of both anaerobic species and coagulase-negative staphylococci was low (4-16%). Vaginal pH was recorded at 6.5 +/- 0.3. Estrogenization, which was required for a sustained T. vaginalis infection, did not significantly alter vaginal flora; however, a slight rise in the number of bacterial species isolated per mouse and a drop in vaginal pH (6.2 +/- 0.5) were observed. Trichomonas vaginalis-infected mice did not appear to show significant changes in vaginal flora although vaginal pH was slightly increased. This mouse model could have applications in both immunologic and pathogenic studies of T. vaginalis and, with further modifications, aid in the study of protist-bacterial interactions.

    To determine the frequency, associated factors and relationship with vulvovaginal symptoms and vaginal douching among Turkish women. The cross-sectional, analytical study was conducted at Merkez Efendi Hospital, Manisa, Turkey, from January to June 2014 using a questionnaire. Statistical analysis was carried out using SPSS 17. Of the total 343 women in the study, 91(26.5%) had reported vaginal douching in the preceding year. Statistically significant relationship was determined between the vaginal douching behaviour and couples who had low educationand low income levels, having unplanned pregnancy and had someone in their neighbourhood who douched (p< 0.05 each). The most common reason for using vaginal douching was reported to be cleanliness by 85(93.4%) women, prevention of genital infections 75(82.4%), cleaning after/before sexual intercourse 72(79%), during menstruation 49(54%), prevention of vaginal discharge 69(76%), decreasing of unpleasant odours 65(71.4%) and religious beliefs 46(50.5%). Self-reported history of vaginal infection was significantly more common for women who douched compared those who did not (p< 0.05). Healthcare providers should determine the reason and risky groups of women and educate the women to stop the vaginal douching behaviour and harmful effects of vaginal douching.

    Uncomplicated vulvovaginal candidiasis appears in 75% women of reproductive age. The most frequent causes are Candida albicans (85-95%) or C. glabrata, and infrequently C. krusei, C. tropicalis, C. parapsilosis, C. pseudotropicalis, etc. The aim of the study was to investigate efficiency and safety of fenticonazole for vaginal candidiasis treatment. Therapeutic effect of a single 600 mg fenticonasole vaginal capsule was observed in 417 women, aged 16-67, in five centers in Serbia. In all women, before the treatment, vaginal candidiasis was confirmed by testing of vaginal smear. Based on smear findings and associated symptoms observed on the 7th and 28th day after therapy administration, treatment results were evaluated. On the next day after drug application the patients recorded by using a questionnaire their own feelings on withdrawal symptoms and possible side effects in the period prior to the first control. Control after seven days showed a statistically significant decrease of symptoms. In 385 women, vaginal smear was found negative to yeast and yeast blastospores. Within the first seven days after treatment 84 women had to repeat therapy due to the persistence of symptoms or positive vaginal smear. After 28 days we recorded full recovery in 392 patients, clinical improvement in eight, no change in 16, and deterioration in one patient only. Side effects were very seldom, mostly in the form of a slight redness of the vulva and vagina, and mild itching during several days. Our observations confirmed good efficacy and safety of fenticonazole in the treatment of vaginal candidiasis.

    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 4°C and 25°C. 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.

    Recent research has highlighted controversies in the conceptualisation, diagnosis and treatment of vaginismus. Vaginal trainers are currently the most widely used treatment. Critiques have highlighted concerns that the evidence-base of its effectiveness is limited, with controlled trials reporting disappointing results, and its prescription promotes 'performance-based' sexuality which may be detrimental. Despite this, little has been done to seek women's views about their treatment. This study set out to explore women's experiences of vaginismus treatment with vaginal trainers, and to use their voices to propose guidelines for improving treatment. 13 women who had used vaginal trainers for vaginal penetration difficulties diagnosed as vaginismus were recruited through a specialist clinic, university campuses, and online forums. The women took part in semi-structured individual interviews (face-to-face/telephone/Skype), which were audio-recorded, transcribed verbatim and analysed using Thematic Analysis. Four superordinate themes were elicited and used to draft 'better treatment' guidelines. Themes were: (1) Lack of knowledge, (2) Invalidation of suffering by professionals, (3) Difficult journey, and (4) Making the journey easier. This paper describes themes (3) and (4). Difficult Journey describes the long and arduous 'Journey into treatment', including difficulties asking for help, undergoing physical investigations and negotiating 'the system' of medical referrals. It also describes the sometimes demoralising process of 'being in treatment', which includes emotional and practical demands of treatment. Making the journey easier highlights the importance of and limits to 'partner support'. 'Professional support' comprises personal qualities of professionals/therapeutic relationship, the value of specialist skills and knowledge and the need for facilitating couple communication about vaginismus. 'Peer support/helping each other' describes the importance of

    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.

    Methods to improve the radiation tolerance of silicon cells for spacecraft use are described. The major emphasis of the program was to reduce the process-induced carbon and oxygen impurities in the junction and base regions of the solar cell, and to measure the effect of reduced impurity levels on the radiation tolerance of cells. Substrates of 0.1, 1.0 and 10.0 ohm-cm float-zone material were used as starting material in the process sequence. High-dose, low-energy ion implantation was used to form the junction in n+p structures. Implant annealing was performed by conventional furnace techniques and by pulsed laser and pulsed electron beam annealing. Cells were tested for radiation tolerance at Spire and NASA-LeRC. After irradiation by 1 MeV electrons to a fluence of 10 to the 16th power per sq cm, the cells tested at Spire showed no significant process induced variations in radiation tolerance. However, for cells tested at Lewis to a fluence of 10 to the 15th power per sq cm, ion-implanted cells annealed in vacuum by pulsed electron beam consistently showed the best radiation tolerance for all cell resistivities.

  11. Obstetric and gynecological diseases and complications resulting from vaginal dysbacteriosis.

    Accurate knowledge of the composition and ecology of vaginal microbial environment of a healthy woman is necessary for the understanding of normal flora and how to reduce the risk for diseases. Vagina and its microflora form a balanced ecosystem in which dominated bacteria are vaginal lactobacilli. There are dynamic changes in this ecosystem having structure and composition depending on many factors. The term dysbacteriosis defines any movement outside the normal range for the given biotope of obligate and/or facultative microflora. Such a change in the quantity and quality of the respective microbial balance is fraught with danger and requires correction and recovery. The purpose of this overview is to examine obstetric and gynecological diseases that can cause vaginal impaired microbial balance. Vaginal dysbacteriosis is a cause, predecessor, and often also consequence of vaginal infections. In essence, any vaginal infection can be seen as dysbacteriosis, developed to the most severe extent. Here, there is a dominant microorganism other than lactic acid bacteria in the vagina (clinically manifested or not, respectively), depletion of defense mechanisms of the vagina associated with the shift of lactobacilli from their dominant role in the vaginal balance, decrease in their number and species diversity, and a resulting change in the healthy status of the vagina. Vaginal dysbacteriosis can be found in pathogenetic mechanism, whereby many obstetric and gynecological diseases develop. Most of these diseases lead directly to increased maternal and infant morbidity and mortality, so it is important to understand the reasons for them and the arrangements for their prevention.

    Permanent seed implantation (PSI) brachytherapy is a highly conformal form of radiation therapy but is challenged with dose inhomogeneity due to its utilization of low energy radiation sources. Gold nanoparticles (AuNP) conjugated with electron emitting radionuclides have recently been developed as a novel form of brachytherapy and can aid in homogenizing dose through physical distribution of radiolabeled AuNP when injected intratumorally (IT) in suspension. However, the distribution is unpredictable and precise placement of many injections would be difficult. Previously, we reported the design of a nanoparticle depot (NPD) that can be implanted using PSI techniques and which facilitates controlled release of AuNP. We report here the 3D dose distribution resulting from a NPD incorporating AuNP labeled with electron emitters (90Y, 177Lu, 111In) of different energies using Monte Carlo based voxel level dosimetry. The MCNP5 Monte Carlo radiation transport code was used to assess differences in dose distribution from simulated NPD and conventional brachytherapy sources, positioned in breast tissue simulating material. We further compare these dose distributions in mice bearing subcutaneous human breast cancer xenografts implanted with 177Lu-AuNP NPD, or injected IT with 177Lu-AuNP in suspension. The radioactivity distributions were derived from registered SPECT/CT images and time-dependent dose was estimated. Results demonstrated that the dose distribution from NPD reduced the maximum dose 3-fold when compared to conventional seeds. For simulated NPD, as well as NPD implanted in vivo, 90Y delivered the most homogeneous dose distribution. The tumor radioactivity in mice IT injected with 177Lu-AuNP redistributed while radioactivity in the NPD remained confined to the implant site. The dose distribution from radiolabeled AuNP NPD were predictable and concentric in contrast to IT injected radiolabeled AuNP, which provided irregular and temporally variant dose distributions

    For the last one hundred years or so doctors have been confronted with the phenomenon of vaginism as a functional sexual disturbance. 70 years ago the psychogenetic nature of this disturbance was recognized, and yet gynaecologists and surgeons are still suggesting and practising surgical and mechanical interventions at the vaginal orifice. This is indeed regrettable - and not only because such attempts remain unsuccessful: in this manner doctors are fixed on the idea of an organic cause of the disturbance instead of motivating the patients to undergo consultative treatment. Vaginism may even entail psychosocial advantages for the women in some cases.

    Vulvovaginal candidiasis (VVC) is an insidious infection that afflicts a large proportion of women of all ages, and 5 to 8% of affected women experience recurrent VVC (RVVC). The aim of this study was to explore the possible importance of vaginal bacterial communities in reducing the risk of RVVC. The species composition and diversity of microbial communities were evaluated for 42 women with and without frequent VVC based on profiles of terminal restriction fragment polymorphisms of 16S rRNA genes and phylogenetic analysis of cloned 16S rRNA gene sequences from the numerically dominant microbial populations. The data showed that there were no significant differences between the vaginal microbial communities of women in the two groups (likelihood score, 5.948; bootstrap P value, 0.26). Moreover, no novel bacteria were found in the communities of women with frequent VVC. The vaginal communities of most women in both groups (38/42; 90%) were dominated by species of Lactobacillus. The results of this study failed to provide evidence for the existence of altered or unusual vaginal bacterial communities in women who have frequent VVC compared to women who do not have frequent VVC. The findings suggest that commensal vaginal bacterial species may not be able to prevent VVC.

    Congenital urethrovaginal fistula is an extremely rare genitourinary anomaly. Literature search identified only five reported cases, all of which were associated with urogenital abnormalities. Transverse vaginal septum is another rare condition, resulting from abnormalities in the vertical fusion between the vaginal components of the Mullerian ducts and the urogenital sinus; and associated fistulous connection of the vagina with the urethra is even rarer. Herein we describe the case of a 35-year-old woman who presented with dyspareunia, and a 1-year history of infertility, who was found to have a urethrovaginal fistula with low transverse vaginal septum. The patient was successfully treated with excision of the septum and closure of the urethrovaginal fistula. © 2016 Japan Society of Obstetrics and Gynecology.

    There is increasing appreciation of the role that vaginal microbiota play in health and disease throughout a woman's lifespan. This has been driven partly by molecular techniques that enable detailed identification and characterisation of microbial community structures. However, these methods do not enable assessment of the biochemical and immunological interactions between host and vaginal microbiota involved in pathophysiology. This review examines our current knowledge of the relationships that exist between vaginal microbiota and the host at the level of the vaginal mucosal interface. We also consider methodological approaches to microbiomic, immunologic and metabolic profiling that permit assessment of these interactions. Integration of information derived from these platforms brings the potential for biomarker discovery, disease risk stratification and improved understanding of the mechanisms regulating vaginal microbial community dynamics in health and disease.

    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

    There is an increasing number of patients with cardiac implantable electronic devices (CIED), either pacemakers or defibrillators, who are receiving a course of radiotherapy. Several guidelines have been published by national societies, but no Spanish national guidelines for management of these patients have been published. More importantly, national clinical practice regarding these patients is not standardised. Members of the Spanish Breast Cancer Radiation Oncology Group (GEORM in Spanish) were surveyed through an online questionnaire on behalf of the Spanish radiation oncology departments. Only 39.3% of the Spanish radiation oncology departments have policies aimed at CIED carrier patients. Regardless of that, 96.4% of those who responded to the survey refer these patients to their Cardiology department before the start of the course of radiotherapy, and 17.8% of respondents said to manipulate the CIED without any cardiology department direction. A wide range of responses was obtained related to concepts such as "distance from the irradiation field to the CIED" or "safe accumulated doses". Our results demonstrate the need for national guidelines for CIED patients and the need to promote educational activities addressed to standardise clinical management of these patients in the radiation oncology departments.

    Introduction Vaginal atrophy, which may affect up to 45% of postmenopausal women, is often associated with one or more urinary symptoms, including urgency, increased frequency, nocturia, dysuria, incontinence, and recurrent urinary tract infection. Aims To provide an overview of the current literature regarding cellular and clinical aspects of vaginal atrophy and response to treatment with local vaginal estrogen therapy. Methods PubMed searches through February 2012 were conducted using the terms “vaginal atrophy,” “atrophic vaginitis,” and “vulvovaginal atrophy.” 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.

    Eighty-one patients with clinical diagnosis of aerobic vaginitis (AV) were included in the study. The patients were randomized for treatment, 45 with kanamycin (100 mg vaginal ovules for 6 days, consecutively) and 36 with meclocycline (35 mg vaginal ovules for 6 days, consecutively). The patients were examined before starting the study, 1-2 days after treatment and 30 days after the end of the study. At the first follow-up the patients showed different levels of symptom reduction. Reduction in the presence of leukocytes, vaginal mucosa burning and itching were statistically significant in the group treated with kanamycin with respect to the group treated with meclocycline. Moreover, there was also reduced isolation of Enterobacteriaeae (97%) in the group treated with kanamycin versus those treated with meclocycline (76%). At the second follow-up, vaginal homeostasis (normalization of pH and presence of lactobacilli) was more evident in the kanamycin-treated group. In conclusion, our data suggest that the topical use of kanamycin could be considered a specific antibiotic for the therapy of this new pathology.

    Vaginal symptoms such as discharge, odor, and itch are among the most common presenting complaints in primary care. We undertook to determine if the symptoms associated with vaginitis (discharge, odor, irritation) occur in normal women. To answer this question, we performed a literature review. We conducted a Medline search using the following terms: "vagina," "vaginal discharge," "secretion," "odors," discharge," "pruritus," "normal," "irritation," "itch," "physical examination," "healthy," "asymptomatic," "quantity," and "physiology." To find additional references we reviewed textbooks in gynecology, primary care, and physical diagnosis and contacted authors. There are few primary studies, and most are not of high quality. Existing data show that the quantity and quality of vaginal discharge in healthy women vary considerably both across individuals and in the same individual during the menstrual cycle. Most studies indicate that discharge is greatest at midcycle. Vaginal fluid contains malodorants, and one study of intact vaginal fluid found it to be malodorous. Two studies found that normal women reported irritative symptoms in the course of their menstrual cycle. The primary literature indicates that there is a wide variation in the normal vagina and that some of the symptoms associated with vaginal abnormality are found in well women. Both clinicians and their patients would benefit from a better understanding of the range of normal as well as what constitutes a meaningful departure from that range.

    Patients with vaginitis were classified into four groups: Group A (prepubertal under-aged females); Group B (pubertal under-aged females); Group C (reproductive age adult females); Group D (postmenopausal adult females). All vaginal specimens underwent microscopy, amine testing, Gram staining and culturing. Overall, 163 patients were included (33, 14, 81 and 35 patients, respectively). The most common infection was bacterial vaginosis (BV), followed by Ureaplasma infection, aerobic vaginitis (AV) and candidiasis. The most common AV-associated organism was Escherichia coli and the most common BV-associated organism was Gardnerella vaginalis. AV was more frequent in Group A, BV in Group C and Ureaplasma infections in Groups C/D. Decreased lactobacilli concentrations were associated with BV in fertile patients (Groups B-C). Although presentation of vaginitis is similar among females of different age in Greece, type and prevalence of pathogens differ. Normal vaginal flora changes are associated with higher risk of vaginitis in specific age groups. Impact Statement The worldwide incidence of reproductive tract infections has been increasing, with specific pathogens being associated with significant risk of morbidity and complications. However, literature data on the distribution of such infections in different age groups is limited. Therefore, the aim of this study was to provide data on the prevalence and causes of vaginitis in adult and non-adult females of all ages. This study has shown that although presentation of vaginitis is similar among females of different age groups and menstrual status in Greece, type and prevalence of responsible pathogens are different among groups. Changes in normal vaginal flora seem to be associated with higher risk of vaginitis in specific age-groups as well. These findings could contribute in adjusting diagnostic and therapeutic strategies for each age group according to the prevailing pathogens. Further research on antibiotic

    This was a randomised, double-blind, placebo-controlled study to evaluate the efficacy and safety of Vitamin C vaginal tablets (250 mg) given once a day in patients suffering from non-specific vaginitis. The total length of the study was 20 days, including a treatment phase of 6 days. The primary end-point was the presence in the two groups of non-specific vaginitis 1 and 2 weeks after the end of treatment, as assessed by at least 3 out of the 4 characteristic symptoms: discharge, fishy odour, vaginal pH >/= 4.7, and presence of clue cells. Secondary end-points were the individual symptoms and signs, above reported, and pruritus, fever, superinfections, microscopic findings on vaginal smear, and colposcopy. One hundred female patients aged 18 years or older and suffering from non-specific vaginitis were included in the study after giving their informed consent. Fifty were randomised to the active treatment and 50 to placebo. Seven patients, three in the Vitamin C group and four in the placebo group, were lost to follow-up and did not complete the treatment period. Two patients in the active group showed protocol deviations (age under 18 years and HIV-positive, respectively). The two groups resulted comparable for demographics, history and baseline clinical picture. A cluster analysis of the four main symptoms showed a statistically significant difference between the active group and the placebo group; significantly more patients were still affected by non-specific vaginitis after placebo (35.7%) compared to patients treated with Vitamin C tablets (14.0%). The meaningful secondary variable, referring to the microscopic examination of vaginal smear, supported the trend for efficacy in the Vitamin C treated group. The clue cells disappeared in 79% of patients treated with the drug and in 53% of patients on placebo. Similarly, bacteria disappeared in 77 and 54%, respectively, while lactobacilli reappeared in 79.1 and 53.3%, respectively. Vaginal pH values decreased

    Do metabolites in vaginal samples vary between women with different vaginal disorders. Cross-sectional study. Campinas, Brazil. Seventy-seven women (39.9%) with no vaginal disorder, 52 women (26.9%) with vulvovaginal candidiasis (VVC), 43 women (22.3%) with bacterial vaginosis (BV), and 21 women (10.9%) with cytolytic vaginosis (CTV). Concentrations of D- and L-lactic acid, extracellular matrix metalloproteinase inducer (EMMPRIN), and matrix metalloproteinase-8 (MMP-8), and the influence of Candida albicans on EMMPRIN production by cultured vaginal epithelial cells, were determined by enzyme-linked immunosorbent assay (ELISA). Associations were determined by the Mann-Whitney U-test and by Spearman's rank correlation test. Metabolite levels and their correlation with diagnoses. Vaginal concentrations of D- and L-lactic acid were reduced from control levels in BV (P < 0.0001); L-lactic acid levels were elevated in CTV (P = 0.0116). EMMPRIN and MMP-8 concentrations were elevated in VVC (P < 0.0001). EMMPRIN and L-lactic acid concentrations (P ≤ 0.008), but not EMMPRIN and D-lactic acid, were correlated in all groups. EMMPRIN also increased in proportion with the ratio of L- to D-lactic acid in controls and in women with BV (P ≤ 0.009). Concentrations of EMMPRIN and MMP-8 were correlated in controls and women with VVC (P ≤ 0.0002). Candida albicans induced EMMPRIN release from vaginal epithelial cells. Vaginal secretions from women with BV are deficient in D- and L-lactic acid, women with VVC have elevated EMMPRIN and MMP-8 levels, and women with CTV have elevated L-lactic acid levels. These deviations may contribute to the clinical signs, symptoms, and sequelae that are characteristic of these disorders. © 2014 Royal College of Obstetricians and Gynaecologists.

    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 3.8 cm (standard deviation, 1.6). Median operative time was 50 minutes (range, 45-90). Blood loss was minimal (50-100 mL). No perioperative complications occurred. Median vaginal length at discharge was 11.3 cm (range, 9-13). Sexual intercourse could be resumed around 10 weeks after surgery. At a median follow-up of 33.8 months (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. Copyright © 2016 AAGL. Published by Elsevier Inc.

    Epithelial cells lining the vagina are major components of genital tract immunity. The influence of the vaginal microbiome on properties of host epithelial cells is largely unexplored. We evaluated whether differences in the most abundant lactobacilli species or bacterial genera in the vagina of first trimester pregnant women were associated with variations in the extent of stress and autophagy in vaginal epithelial cells. Vaginal swabs from 154 first trimester pregnant women were analyzed for bacterial composition by amplification and sequencing of the V1-V3 region of bacterial 16S rRNA genes. Vaginal epithelial cells were lysed and autophagy quantitated by measurement of p62. Intracellular levels of the inducible 70kDa heat shock protein (hsp70), an indicator of cell stress and an autophagy inhibitor, were determined. When Lactobacillus crispatus was the most abundant member of the vaginal microbiota, epithelial p62 and hsp70 levels were lowest as compared to when other bacterial taxa were most abundant. The highest concentrations of p62 and hsp70 were associated with Streptococcus and Bifidobacterium abundance. The p62 level associated with Gardnerella abundance was lower than that observed when lactobacilli other than L. crispatus were most abundant. In conclusion, in the first trimester of pregnancy the abundance of different bacterial taxa is associated with variations in autophagy and magnitude of the stress response in vaginal epithelial cells.

    It is known that psychological stress affects reproduction in women, but it is unknown whether the effect is by impairing implantation. Although studies suggest that long periods of auditory or restraint stress may inhibit implantation in rats and mice, the exact stage of pregnancy at which stress impairs implantation is unclear. Furthermore, whether stress impairs implantation by decreasing the heparin-binding epidermal growth factor-like growth factor (HB-EGF), estrogen and/or progesterone and whether by acting on embryos or on the uterus need further investigations. In this study, a 24-h restraint stress was initiated at 15:30 of day 3 (regimen 1) or at 07:30 (regimen 2) or 15:30 of day 4 (regimen 3) of pregnancy (vaginal plug  =  day 1) to observe effects of restraint stress applied at different peri-implantation stages on implantation. Among the three regimens, whereas regimens 1 and 3 affected neither term pregnancy nor litter size, regimen 2 reduced both. Further observations indicated that regimen 2 of restraint stress also delayed blastocyst hatching and the attachment reaction, decreased serum concentrations of progesterone and estradiol, and down regulated the expression of HB-EGF in both the endometrium and blastocysts. Taken together, the results suggested that restraint stress inhibited mouse implantation in a temporal window-dependent manner and by impairing blastocyst activation and hatching and uterine receptivity via down-regulating HB-EGF, estrogen and progesterone. Thus, the stress applied within the implantation window impaired implantation by acting on both embryos and the uterus. PMID:24244689

    In this letter, the authors present first observation of terahertz generation from Fe implantation of LiNbO3 crystal substrate. LiNbO3 single crystal is grown by Czochralski method. Metal nanoparticles synthesized by Fe ion implantation were implanted into LiNbO3 single crystal using metal vapor vacuum arc (MEVVA) ion source. 1 kHz, 35 fs laser pulsed centered at 800 nm were focused onto the samples. Terahertz was generated via optical rectification. The findings suggest that under the investigated implantation parameter, a spectral component in excess of 0.44 THz emission were found from Fe ion implantation of LiNbO3.

    To describe a simple and efficient technique for suturing the vaginal cuff in robotic-assisted single-site hysterectomy using barbed suture and a straight needle. Consecutive patients undergoing robotic-assisted single-site hysterectomy from February 2014 to August 2015 at Dong San Hospital, Keimyung University were included. Surgeons used two barbed sutures in a running fashion to close the vaginal cuff. A barbed suture was exclusively used with a straightened needle in upward direction from posterior vaginal cuff to anterior vaginal cuff which played a pivotal role for closure. A total of 100 patients underwent robotic-assisted single-site hysterectomy. The total operation time was 132.5 min and vaginal cuff closure time was 12.0 min. There were no postoperative complications; vaginal cuff dehiscence, vaginal cuff infection, and vaginal bleeding that require surgical intervention or admission. The use of barbed suture with straightened needle to close the vaginal cuff in robotic-assisted single-site hysterectomy is easy to perform and demonstrates safety and efficacy. This technique offers secure, fast, and effective incision closure.

    Magnetic resonance imaging (MRI) is the preferred modality for soft tissue imaging because of its nonionizing radiation and lack of contrast agent. Due to interactions between the MR system and active implantable medical devices (AIMDs), patients with implants such as pacemakers are generally denied access to MRI, which presents a detriment to that population. It has been estimated that 50-75% of patients with a cardiac device were denied access to MRI scanning and, moreover, that 17% of pacemaker patients need an MRI within 12 months of implantation [1]. In recent years, AIMD manufacturers, such as Biotronik, have assessed the conditional safety of devices in MRI.

    Objective: To compare the efficacy and safety of a 3-day regimen of clindamycin vaginal ovules with a 7-day regimen of clindamycin vaginal cream for the treatment of bacterial vaginosis (BV) Methods: Women with a clinical diagnosis of BV were treated with a 3-day course of clindamycin ovules or a 7-day course of clindamycin cream administered intravaginally. Three hundred and eighty-four patients received study drug and were included in the evaluable patient population (ovule group, n = 204; cream group, n = 180). Assessments included pelvic examination and diagnostic testing. Primary efficacy endpoints were a resolution of two of three diagnostic criteria at the first follow-up visit and three of three diagnostic criteria at the second. Results: Cure rates in the evaluable patient population were similar between treatment groups: 53.7% (109/204) for the ovule group and 47.8% (85/180) for the cream group (p = 0.2471, 95% CI– 4.1–16.0%). The most commonly reported medical event, vulvovaginal pruritus, had similar incidence in both treatment groups. Conclusions: A 3-day course of clindamycin vaginal ovules is as effective and well-tolerated as a 7-day course of clindamycin vaginal cream in the treatment of BV. PMID:11368263

    To review the results of vaginal hysterectomies in patients without uterine prolapse. Retrospective chart review. University affiliated hospital, Hong Kong. All patients who had vaginal hysterectomies in the absence of uterine prolapse from 1999 to 2005 inclusive (first period) and 2006 to 2009 inclusive (second period). The number of such hysterectomies, indications, operative procedures, complications, use of preoperative gonadotropin-releasing hormone agonist, and concomitant vaginal salpingo-oophorectomies performed. In all, 94 and 98 patients fulfilling the necessary inclusion criteria within the two respective periods underwent vaginal hysterectomy. The indications for hysterectomy in the respective groups were similar, and 89 (95%) and 90 (92%) of the patients were Chinese. The respective proportions having additional procedures were 11% versus 23% (P=0.018) and the respective vaginal bilateral salpingo-oophorectomy rates were 1% versus 15% (P<0.001). The vault haematoma rate decreased significantly in the second period (from 12% to 1%; P=0.002). There were no significant differences between the periods with respect to mean operative blood losses, uterine weights, and operating times. The use of gonadotropin-releasing hormone agonist resulted in reduced mean uterine sizes (12 weeks vs 10 weeks; P=0.041). A decreasing trend in mean operating times and blood losses was also observed after such use. Vaginal hysterectomy and bilateral salpingo-oophorectomies were successfully performed in 12 (80%) patients without laparoscopic assistance. For this procedure, a learning curve was also evident. Surgeons' experience can influence the complication rate and the chance of successful vaginal salpingo-oophorectomy. More liberal use of gonadotropin-releasing hormone agonist may further reduce the complication rate and allow more vaginal hysterectomies.

    The medical care day by day and more and more is associated with and reliant upon concepts and advances of electronics and electromagnetics. Numerous medical devices are implanted in the body for medical use. Tissue implanted devices are of great interest for wireless medical applications due to the promising of different clinical usage to promote a patient independence. It can be used in hospitals, health care facilities and home to transmit patient measurement data, such as pulse and respiration rates to a nearby receiver, permitting greater patient mobility and increased comfort. As this service permits remote monitoring of several patients simultaneously it could also potentially decrease health care costs. Advancement in radio frequency communications and miniaturization of bioelectronics are supporting medical implant applications. A central component of wireless implanted device is an antenna and there are several issues to consider when designing an in-body antenna, including power consumption, size, frequency, biocompatibility and the unique RF transmission challenges posed by the human body. The radiation characteristics of such devices are important in terms of both safety and performance. The implanted antenna and human body as a medium for wireless communication are discussed over Medical Implant Communications Service (MICS) band in the frequency range of 402-405MHz.

    Despite being linked to improving patient outcomes and limiting costs, the use of vaginal hysterectomy is on the wane. Although a combination of reasons might explain this trend, one cause is a lack of practical training. An appropriate teaching model must therefore be devised. Currently, only low-fidelity simulators exist. Ewes provide an appropriate model for pelvic anatomy and are well-suited for testing vaginal mesh properties. This article sets out a vaginal hysterectomy procedure for use as an education and training model. A multiparous ewe was the model. Surgery was performed under general anesthesia. The ewe was in a lithotomy position resembling that assumed by women on the operating table. Two vaginal hysterectomies were performed on two ewes, following every step precisely as if the model were human. Each surgical step of vaginal hysterectomy performed on the ewe and on a woman were compared side by side. We identified that all surgical steps were particularly similar. The main limitations of this model are costs ($500/procedure), logistic problems (housing large animals), and public opposition to animal training models. The ewe appears to be an appropriate model for teaching and training of vaginal hysterectomy.

    To determine whether vaginitis due to Saccharomyces cerevisiae can be caused by exposure to exogenous sources of baker's yeast. Eight women with S cerevisiae vaginitis were identified from a cohort of women referred for the evaluation of chronic vaginal symptoms. In those with high-level exposure to exogenous sources of S cerevisiae, isolates from the vagina and those sources were sent in a blinded fashion for contour-clamped homogeneous electric-field electrophoresis. Four women from a cohort of approximately 750 referred patients had high-level exposures to S cerevisiae. In one of these patients, electrophoresis analysis revealed similarities between the strains isolated from her vagina, her husband's fingers, and the yeast he used in his pizza shop. Saccharomyces cerevisiae vaginitis can be the result of the inoculation of this yeast from exogenous sources.

    Identification of vaginal fluids is an important step in the process of sexual assaults confirmation. Advances in both microbiology and molecular biology defined technical approaches allowing the discrimination of body fluids. These protocols are based on the identification of specific bacterial communities by microfloraDNA (mfDNA) amplification. A multiplex real time-PCR assay (ForFLUID kit) has been developed for identifying biological fluids and for discrimination among vaginal, oral and fecal samples. In order to test its efficacy and reliability of the assay in the identification of vaginal fluids, an interlaboratory evaluation has been performed on homogeneous vaginal swabs. All the involved laboratories were able to correctly recognize all the vaginal swabs, and no false positives were identified when the assay was applied on non-vaginal samples. The assay represents an useful molecular tool that can be easily adopted by forensic geneticists involved in vaginal fluid identification.

    Results of treatment of 151 cases of vaginitis in patients attending a leukorrhea clinic were studied. The incidence of each type of vaginitis is recorded. Analysis of results of treatment with six compounds currently used in the therapy of vaginitis indicated that acetarsol or pimaricin compounds, with their broader spectra of activity, appeared to be most useful, prior to establishment of a definite diagnosis by means of cultures. Chlordantoin is an effective antifungal agent and is associated with a high percentage of “culture cures”. Resistant cases should be investigated for diabetes mellitus, and many are aided by a low carbohydrate diet. Metronidazole was used only for resistant cases of trichomoniasis, with a cure rate of over 80% when both partners were treated simultaneously. Triple-sulfa vaginal cream was effective in over 80% of patients with nonspecific vaginitis; no cases of resistant bacterial infections were encountered. Dienestrol cream was effective in relieving the symptoms of atrophic vaginitis. PMID:14144540

A cross-sectional, observational study. Three outpatient clinics in Riga. From July 2009 until January 2010, 139 unselected consecutive pregnant women at the first prenatal visit. Pregnant women were submitted to an interview, vaginal examination and vaginal specimen collection for pH measurement and native microscopy. Vaginal pH ≥4.5 was considered as elevated. Abnormal bacterial microflora was classified according to Donders. Elevated vaginal pH was significantly associated with bacterial vaginosis (p < 0.001), aerobic vaginitis (p < 0.001) and mixed aerobic vaginitis and bacterial vaginosis flora (p < 0.001) and presence of sperm cells in the smears (p= 0.024). Most cases with sperm were associated with abnormal vaginal flora. Normal lactobacillary morphotypes were more often found in the pH ≤4.4 group (p < 0.001), while leptosomic and short types were found more frequently with increased pH. Elevated vaginal pH is associated with different types of abnormal vaginal flora and the presence of sperm cells. © 2010 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2010 Nordic Federation of Societies of Obstetrics and Gynecology.

    Despite the demonstrated safety of a trial of labor for pregnancies with a vertex-presenting twin and clinical guidelines in support of this plan, the rate of planned cesarean delivery for twin pregnancies remains high. This high rate, as well as variation in cesarean rates for twin pregnancies across providers, may be influenced strongly by concern about delivery of the second twin, particularly when it is in a nonvertex presentation. There are limited data in the literature that has examined the impact of the position of the nonpresenting twin on successful vaginal delivery or maternal/neonatal morbidity. We hypothesized that nonvertex presentation of the second twin would be associated with lower rates of successful vaginal birth for those patients attempting labor. This institutional review board-approved, retrospective cohort study of women who labored with twin pregnancies in a single urban hospital from 2007-2011. We included women with vertex-presenting first twins at >32 weeks gestation without a contraindication to labor and excluded those with uterine scar or lethal fetal anomaly. Vaginal delivery rates were evaluated according to vertex or nonvertex presentation of the second twin at admission and again at delivery. Maternal and neonatal morbidities were evaluated separately. Logistic regression was used to control for multiple confounders. Seven hundred sixteen patients met the inclusion criteria; 349 patients (49%) underwent a trial of labor. This included 73% (296/406) of eligible vertex/vertex twins and 17% (53/310) eligible vertex/nonvertex twins (P < .01). When compared with laboring patients with vertex/vertex-presenting twins, those with vertex/nonvertex twins were younger (median age, 32 vs 33 years; P = .05), were more often multiparous (60% vs 43%; P = .02), and were less likely to have hypertension (13% vs 27%; P = .03).

The predictive value of a positive test was 94%, but that of a negative test was only 55%. A strong association between the presence of Gardnerella vaginalis, anaerobes, a vaginal pH of above 4.5, and amines was found not only in non-specific vaginitis, but also in trichomonal and gonococcal infection. A variety of primary changes may encourage the multiplication of both gardnerellae and anaerobes and their presence in non-specific vaginitis may be a secondary rather than a primary event.

    To estimate the prevalence of bacterial vaginosis (BV), candidiasis and trichomoniasis and compare the findings of physical examination of the vaginal secretion with the microbiological diagnosis obtained by cytology study of a vaginal smear using the Papanicolaou method. A cross-sectional study of 302 women aged 20 to 87 years, interviewed and submitted to a gynecology test for the evaluation of vaginal secretion and collection of a cytology smear, from June 2012 to May 2013. Sensitivity analyses were carried out and specificity, positive predictive value (PPV) and negative predictive value (NPV) with their respective 95%CI were determined to assess the accuracy of the characteristics of vaginal secretion in relation to the microbiological diagnosis of the cytology smear . The kappa index (k) was used to assess the degree of agreement between the clinical features of vaginal secretion and the microbiological findings obtained by cytology. RESULTS The prevalence of BV, candidiasis and trichomoniasis was 25.5, 9.3 and 2.0%, respectively. The sensitivity, specificity, PPV and NPV of the clinical characteristics of vaginal secretion for the cytological diagnosis of BV were 74, 78.6, 54.3 and 89.9%, respectively. The sensitivity, specificity, PPV and the NPV of the clinical characteristics of vaginal secretion for the cytological diagnosis of candidiasis were 46.4, 86.2, 25.5 and 94%, respectively. The correlation between the clinical evaluation of vaginal secretion and the microbiological diagnosis of BV, candidiasis and trichomoniasis, assessed by the kappa index, was 0.47, 0.23 and 0.28, respectively. CONCLUSION The most common cause of abnormal vaginal secretion was BV. The clinical evaluation of vaginal secretion presented amoderate to weak agreement with the microbiological diagnosis, indicating the need for complementary investigation of the clinical findings of abnormal vaginal secretion.

    We have performed 26 vaginal radical trachelectomies (RTs) for patients with early invasive uterine cervical cancer since 2003 and, to date, have experienced 8 deliveries. The procedure has a high risk for preterm labor and the subsequent occurrence of preterm premature rupture of membranes (pPROM). We report the present situation and the limits of follow-up of pregnancy after vaginal RT. Our operative procedure is based on that of Dargent et al. We usually amputate the cervix approximately 10 mm below the isthmus. To remove the parametrium, we cut at the level of type II hysterectomy. Pregnancy courses after vaginal RT were studied in 8 patients with respect to symptoms, cervical length, and several infectious signs. We recommended that patients enter hospital early in their second trimester, and prophylactic daily vaginal disinfection with povidone-iodine and an ulinastatin vaginal suppository were administered. Careful checking for vaginal infectious signs, as well as cervical length and abdominal tension of patients was also performed. Four patients followed up with this modality were able to continue their pregnancies until late in the third trimester. However, this follow-up modality was not effective for patients who showed cervical incompetence due to slack cervical cerclage. They suffered from pPROM at 26 and 19 weeks of gestation. We need a new approach for the management of pregnant patients after vaginal RT with cervical incompetence due to slack cervical cerclage to prevent cervical infection.

    Vaginal infections are responsible for a large proportion of gynaecological outpatient visits. Those are bacterial vaginosis (BV), vulvovaginal candidosis (VVC), aerobic vaginitis (AV) associated with aerobic bacteria, and mixed infections. Usual treatments show similar acceptable short-term efficacy, but frequent recurrences and increasing microbial resistance are unsolved issues. Furthermore, vaginal infections are associated with a variety of serious adverse outcomes in pregnancy and generally have a major impact on quality of life. Identifying the correct therapy can be challenging for the clinician, particularly in mixed infections. Dequalinium chloride (DQC) is an anti-microbial antiseptic agent with a broad bactericidal and fungicidal activity. Systemic absorption after vaginal application of DQC is very low and systemic effects negligible. Vaginal DQC (Fluomizin vaginal tablets) has been shown to have equal clinical efficacy as clindamycin in the treatment of BV. Its broad antimicrobial activity makes it appropriate for the treatment of mixed vaginal infections and in case of uncertain diagnosis. Moreover, resistance of pathogens is unlikely due to its multiple mode of action, and vaginal DQC provides also a reduced risk for post-treatment vaginal infections. Vaginal DQC (10 mg) as 6-day therapy offers a safe and effective option for empiric therapy of different vaginal infections in daily practice. This review summarizes the available and relevant pharmacological and clinical data for the therapy of vaginal infections with vaginal DQC and provides the rationale for its use in daily gynaecologic practice.

    Micro-gap formation at the implant-abutment interface of two-piece dental implants was investigated in vitro using high-resolution radiography in combination with hard X-ray synchrotron radiation. Images were taken with the specimen under different mechanical loads of up to 100 N. The aim of this investigation was to prove the existence of micro-gaps for implants with conical connections as well as to study the mechanical behavior of the mating zone of conical implants during loading. Synchrotron-based radiography in comparison with classical laboratory radiography yields high spatial resolution in combination with high contrast even when exploiting micro-sized features in highly attenuating objects. The first illustration of a micro-gap which was previously indistinguishable by laboratory methods underlines that the complex micro-mechanical behavior of implants requires further in vitro investigations where synchrotron-based micro-imaging is one of the prerequisites.

    To evaluate changes in the resident microbial population in the cranial vaginal mucosa induced by a progesterone-releasing intravaginal device (PRID) compared to the vaginal microbiota of cows with reproductive disorders. Vaginal discharge was evaluated by clinical examination and a Vaginitis Diagnosis Score was performed by exfoliative cytology. All samples classified as positive and some classified as negative by clinical evaluation were later diagnosed as positive for vaginitis by cytological analysis. Bacterial diversity profiles were performed by PCR-DGGE and clustered according to the reproductive health status of the specimens, revealing a correspondence between the structures of the communities in the vagina and the clinical profile. Representative bands from each group were sequenced and identified as Ruminococcus sp., Dialister sp., Escherichia sp./Shigella sp., Virgibacillus sp., Campylobacter sp., Helcoccoccus sp., Staphylococcus sp., Bacillus sp., Actinopolymorpha sp., Exiguobacterium sp., Haemophilus sp./Histophilus sp., Aeribacillus sp., Porphyromonas sp., Lactobacillus sp. and Clostridium sp. Our results contribute to the knowledge of the vaginal microbiome in synchronized heifers showing positive or negative clinical vaginitis. This study contributes to the understanding of a dynamic vaginal colonization by bacterial consortiums during the synchronization with a widely used PRID protocol. Also, the results reveal the presence of well-known metritis-related pathogens as well as emerging uterine opportunistic pathogens. The provided information will allow to carry out further studies to elucidate functional roles of these native micro-organisms in the bovine reproductive tract. © 2016 The Society for Applied Microbiology.

    The aim of this observational national multi-centre study was to describe medical care of vaginal infections resisting a primary probabilistic treatment. Two hundred and seventy female patients were included during a 9-month period (from 2013, March 20th to 2013, December 7th) by 155 gynaecologists located throughout France. All patients were presenting a vulvo-vaginitis episode which started about three weeks ago and which was characterized by leucorrhea (93 % cases), itching (88 % cases) and/or vulvar and/or vaginal irritation (88 % cases). In most cases, this episode was previously treated by a short course of an azole antifungal medication. This treatment was initiated by the patient herself without any doctor's prescription in six out of 10 cases and had no influence on the evolution of the original clinical symptoms. Second line treatments included azole antifungal medications (56 % cases), local fixed combinations (antifungal agent and bactericidal antibiotic) (29 %), metronidazole (9 %), oral antibiotics (7.4 %). At the end of the treatment, 85 % patients recovered from vaginitis symptoms. The recovery rate was 82.6 % for patients who got a bacteriological examination and 87.6 % for patients who were treated without any bacteriological examination. The difference is not statistically significant. These results seem to show that a probabilistic medical care is as effective as (but probably more economical than) a therapeutic strategy guided by the results of further examinations in case of failure of a primary treatment. This conclusion should be confirmed by a medico-economic comparison after randomization. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Several causes can disturb the quality of life in postmenopausal women. Stress, urinary incontinence is one of the factors that can influence the quality of life of women, since they evade social activities and limit their behavior. Vulvovaginal disorders adversely impacts sexual action, psychosocial health, and partner relationships. The aim of this study was to examine the therapeutic properties of vaginal cream of royal jelly and estrogen on quality of life, sexual and urinary problems in postmenopausal women. This study was a randomized controlled clinical trial that was done on 90 married postmenopausal women 50 to 65-year-old. A total of 90 women were randomly distributed to three groups and were treated with vaginal cream of royal jelly 15%, lubricant, and conjugated estrogens for three months. Before and after intervention, quality of life and vaginal cytology were evaluated. Data was analysed by SPSS 16 using ANOVA and Tukey tests. The results expressed that vaginal royal jelly is considerably more effective than conjugated estrogens and lubricant in the improvement of quality of life, sexual and urinary function in postmenopausal women (p<0.05). Results of Pap smear showed that improvement of vaginal atrophy in conjugated estrogens group was better than other groups (p<0.001), and there was no significant difference between lubricant and royal jelly groups (p=0.89). The effectiveness of vaginal royal jelly in treatment of sexual and urinary problems of postmenopausal women is related to its estrogenic properties and could be suitable in promotion of life quality in postmenopausal women.

    We analyzed sensitivity of 123 vaginal lactobacillus strains to antibacterial substances. All lactobacillus strains were sensitive to ampicillin, cefazolin, cefotaxime, and vancomycin, and insensitive to metronidazole, trimethoprim/sulfamethoxazole, and levofloxacin. Lactobacillus strains demonstrated different sensitivity to gentamycin, clindamycin, erythromycin, ciprofloxacin, and tetracycline. The phenomenon of preferential selective influence of antibacterial drugs on the composition of lactobacilli of the vaginal microbiota, in which some lactobacilli survive as part of the vaginal microbiota and have a selective advantage over other types of lactobacilli, should be taken into account during treatment of vaginal infections and dysbiosis.

    A 32-y-old married woman was admitted with intense vaginal discharge with foul odor, itching, groin pain, and infertility for the past 5 y. Candida albicans was isolated from the culture of vaginal swab. The patient was diagnosed with chronic vaginal candida infection. She failed to respond to integrative medicine methods prescribed. Recovery was achieved with the application of apple cider vinegar. Alternative treatment methods can be employed in patients unresponsive to medical therapies. As being one of these methods, application of apple cider vinegar can cure vaginal candida infection.

    There have been several reports describing rectovaginal fistula development after bevacizumab treatment, and these fistulas were diagnosed by CT scan or colonoscopy. We report a case of sigmoid-vaginal fistula diagnosed by fistulography. The case is a 53-year-old woman who was treated for chronic myelogenous leukaemia and gynaecological cancers 8 years previously. At 52 years of age, she was diagnosed with colon cancer and had a partial colectomy performed. One year after surgery, colon cancer recurred, and she was treated with anticancer agents, including bevacizumab. During chemotherapy, she complained of a foul smelling discharge from the vagina. Fistulography revealed a sigmoid-vaginal fistula. This is the first report of vaginal fistulography performed on a patient who was treated with bevacizumab. Fistulography may be useful for detecting sigmoid-vaginal fistula. © 2016 John Wiley & Sons Ltd.

    Vulvar and vaginal atrophy (VVA) is a chronic and progressive medical condition common in postmenopausal women. Symptoms of VVA such as dyspareunia, vaginal dryness, irritation, and itching can negatively impact sexual function and quality of life. The REVIVE (REal Women’s VIews of Treatment Options for Menopausal Vaginal ChangEs) survey assessed knowledge about VVA and recorded attitudes about interactions with healthcare providers (HCPs) and available treatment options for VVA. The REVIVE survey identified unmet needs of women with VVA symptoms such as poor understanding of the condition, poor communication with HCPs despite the presence of vaginal symptoms, and concerns about the safety, convenience, and efficacy of available VVA treatments. HCPs can address these unmet needs by proactively identifying patients with VVA and educating them about the condition as well as discussing treatment preferences and available therapies for VVA.

    1972-01-01

    Techniques were developed for creating bipolar microwave transistors in GaAs by ion implantation doping. The electrical properties of doped layers produced by the implantation of the light ions Be, Mg, and S were studied. Be, Mg, and S are suitable for forming the relatively deep base-collector junction at low ion energies. The electrical characteristics of ion-implanted diodes of both the mesa and planar types were determined. Some n-p-n planar transistor structures were fabricated by implantation of Mg to form the base regions and Si to form the emitters. These devices were found to have reasonably good base-collector and emitter-base junctions, but the current gain beta was small. The low was attributable to radiative recombination in the base region, which was extremely wide.

    Background: In patients undergoing head and neck surgery for various pathologic conditions, implants are one of the best restorative options and are increasing widely used. Therefore, we evaluated the success of dental implants in the irradiated jaws of patients following treatment of oral cancer oral cancer treated patients. Materials and Methods: Data of oral cancer treated patients was collected retrospectively from 2002 to 2008. We took 46 oral cancer treated patients in which implants were placed in irradiated jaws for rehabilitation. Results: It was found that out of 162 dental implants placed, 52 failed. Furthermore, there was no variation in the implant survival rate in between both the jaws. Radiation dose of <50 Gy units also showed significantly increased amount of implant survival rate. Conclusions: Implant survival is multifactorial and depends upon a number of factors like level of radiation exposure in that area, time gap between last radiation doses etc., Further research is required in this field to improve the esthetics and quality of life of cancer treated patients.

    Abstract Background. Evidence suggests that specific vaginal bacteria associated with bacterial vaginosis (BV) may increase the risk of adverse health outcomes in women. Among women participating in a randomized, double-blinded trial, we assessed the effect of periodic presumptive treatment (PPT) on detection of select vaginal bacteria. Methods. High-risk women from the United States and Kenya with a recent vaginal infection received intravaginal metronidazole 750 mg plus miconazole 200 mg or placebo for 5 consecutive nights each month for 12 months. Vaginal fluid specimens were collected via polyester/polyethylene terephthalate swabs every other month and tested for bacteria, using quantitative polymerase chain reaction (PCR) assays targeting the 16S ribosomal RNA gene. The effect of PPT on bacterium detection was assessed among all participants and stratified by country. Results. Of 234 women enrolled, 221 had specimens available for analysis. The proportion of follow-up visits with detectable quantities was lower in the PPT arm versus the placebo arm for the following bacteria: BVAB1, BVAB2, Atopobium vaginae, Leptotrichia/Sneathia, and Megasphaera. The magnitude of reductions was greater among Kenyan participants as compared to US participants. Conclusions. Use of monthly PPT for 1 year reduced colonization with several bacteria strongly associated with BV. The role of PPT to improve vaginal health should be considered, and efforts to improve the impact of PPT regimens are warranted. PMID:28007924

    Gynaecological cancer screening was supplemented with examination of the vaginal microflora and pH in women suffering from vaginal discharge and/or colpitis. In alkaline samples Escherichia coli, Staphylococcus aureus and Candida albicans and, in cervical epithelial cells, herpes simplex virus antigen were of common occurrence, while in samples with acid reaction Trichomonas and, in cervical cells mainly from pregnant women, adenovirus antigen were often detected. Since vaginal pH may be informative of the pathogenic agent(s), its estimation by a rapid, simple and painless procedure, like litmus paper reaction, is recommended.

    We investigated the hypothesis that external (EUS) and internal (IUS) urethral sphincters and urinary bladder (UB) respond to penile thrusting (PT) of vagina in a way that prevents urinary leakage during coitus. Vaginal condom was inflated with air in increments of 50-300 ml and EMG of EUS and IUS and vaginal pressure were recorded; test was repeated after anesthetization of vagina, UB, EUS, and IUS. Vaginal distension effected reduction of vesical pressure but increase of IUS EMG until the 150 ml distension was reached, beyond which more vaginal distension caused no further effect; EUS EMG showed no response. Vaginal distension while vagina, UB, EUS, and IUS had been separately anesthetized, produced no change. Vaginal balloon distension appears to effect vesical relaxation and increased IUS tone. This seems to provide a mechanism to avoid urine leakage during coitus and to occur through a reflex we term 'vagino-urethrovesical reflex'.

    Introduction and hypothesis We present a technique for quantifying inter-individual variability in normal vaginal shape, axis, and dimension, and report findings in healthy women. Methods Eighty women (age: 28~70 years) with normal pelvic organ support underwent supine, multi-planar proton-density MRI. Vaginal width was assessed at five evenly-spaced locations, and vaginal axis, length, and surface area were quantified via ImageJ and MATLAB. Results The mid-sagittal plane angles, relative to the horizontal, of three vaginal axes were 90± 11, 72± 21, and 41± 22° (caudal to cranial, p < 0.001). The mean (± SD) vaginal widths were 17± 5, 24± 4, 30± 7, 41± 9, and 45± 12 mm at the five locations (caudal to cranial, p < 0.001). Mid-sagittal lengths for anterior and posterior vaginal walls were 63± 9 and 98 ± 18 mm respectively. The vaginal surface area was 72 ± 21 cm2 (range: 34 ~ 164 cm2). The coefficient of determination between any demographic variable and any vaginal dimension did not exceed 0.16. Conclusions Large variations in normal vaginal shape, axis, and dimensions were not explained by body size or other demographic variables. This variation has implications for reconstructive surgery, intravaginal and surgical product design, and vaginal drug delivery. PMID:26811115

    Sexually active teens are at significant risk from sexually transmitted infections and girls and women bear the greatest burden of these infections. New methods, such as vaginal microbicides, would provide female controlled options. Microbicides are currently in development and thus it is timely to discuss the progress made and factors that may influence acceptability for teens. Microbicide development presents many challenges, and several different potential mechanisms of action are being explored. There is interest in these products from women and men, and specific preferences are being investigated. Adolescents, due to reproductive system immaturity, developing cognitive abilities and the psychosocial context of their relationships, present a special set of challenges in efforts to foster microbicide use. Vaginal microbicides are on the horizon. Further study into teen issues is required to develop successful strategies for marketing and encouraging adolescent use of microbicides.

    To evaluate the efficacy of lyophilized lactobacilli in combination with 0.03 mg estriol when compared to metronidazole in the treatment of bacterial vaginal infections. Multicenter, randomized, single-blind, active-controlled pilot study in 3 independent gynecological practices in Belgium. Forty-six, 18- to 50-year-old premenopausal women with a disrupted vaginal flora due to a bacterial vaginal infection (bacterial vaginosis, aerobic vaginitis) were included, provided that fresh phase-contrast microscopy of the vaginal fluid showed lactobacillary flora grade 2B or 3. Patients were given a blinded box with either 12 vaginal tablets of Gynoflor® (study medication) or 6 vaginal suppositories containing 500 mg metronidazole (control medication). Eight efficacy variables were studied to assess the status of the vaginal flora at entry, 3-7 days (control 1), 4-6 (control 2) weeks and 4 months after the end of therapy. At control 1, the combined variables equally improved in the lactobacilli group as in the metronidazole group. At control 2, the lactobacillus preparation showed slightly inferior results when compared to metronidazole. At 4 months, this analysis could not be performed due to low numbers, but analysis of recurrence rate and extra medication needed was not different between both groups. Lyophilized lactobacilli in combination with low-dose estriol are equivalent to metronidazole in the short-term treatment of bacterial vaginal infections, but have less effect after 1 month. Further studies are required to evaluate the long-term efficacy of lactobacilli when applied repeatedly. Copyright © 2010 S. Karger AG, Basel.

    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.

    The purpose of this study was to evaluate the local tolerance of vaginal gels (three gels containing dapivirine, the placebo gel, and Conceptrol) with the Slug Mucosal Irritation test and to compare the results with those of the rabbit vaginal irritation test. The irritation potential on the slug mucosa was assessed by the mucus production caused by a repeated treatment for 5 successive days. Additionally, membrane damage was estimated by the protein and enzyme release. By means of a classification prediction model the formulations were classified into four irritation classes. The effect of a 10-day intravaginal application of the gels on the rabbit vaginal and cervical mucosa was evaluated by means of macroscopic and microscopic examination. The placebo and dapivirine gels induced no irritation of the slug mucosa (low mucus production and protein release, no enzyme release) and no vaginal or cervical irritation in rabbits. Conceptrol caused severe irritation of the slug mucosa (increased mucus production, protein release, and enzyme release) and irritation of the rabbit vagina and cervix. The results obtained with the Slug Mucosal Irritation test were comparable to those of the rabbit vaginal irritation test.

    Vaginal candidiasis is a common problem of clinical practice. Many studies have been conducted to explain its origin but only a few have included Polish women. The aim of the study was to determine the prevalence and similarity of oral, anal and vaginal Candida albicans strains isolated from Polish women with vaginal candidiasis. The study involved 20 from 37 recruited women. Swab samples were collected from their vagina, anus, and oral cavity at two-month intervals. All the women were treated with nystatin. Yeast were recovered and identified by the germ-tube test, API /Vitek system, typed by API ZYM and RAPD-PCR. Chi-square test was used to analyze the data. A total of 170 Candida albicans isolates were recovered from 180 samples collected 3 times from 3 sites of 20 women. Positive yeast vaginal cultures were found in all patients before administration of nystatin. Vaginal yeast recovery rate was decreased statistically significant in both follow-up visits (p= 0.001; p= 0.003). The same and different genotypes/biotypes were found concomitantly in a few body sites and/ or repeatedly at time interval from the same body site. The results support the concept of dynamic exchange of yeast within one woman and endogenous or exogenous origin of vaginal candidiasis.

    A novel customized vaginal brachytherapy mould technique has been developed for clinical use. This image-guided technique provides a brachytherapy applicator solution for irregular vaginal vault configuration and/or a wide vaginal apex relative to the vaginal introitus that would be sub-optimally treated with standard cylinders. The customized vaginal applicator is generated by the following process: CT images are obtained with contrast-soaked vaginal packing in situ to highlight unique anatomical detail. A 3-dimensional digital model is developed from the images and subsequently converted into a custom applicator with the use of stereolithography, which is an additive manufacturing technique whereby layers 50-100 μm thick of resin are deposited and polymerized using a laser to create intricate 3-dimensional objects. The density of the applicator and the dose delivered using the custom applicator were both measured to ensure accurate dosimetry. The CT-based densities of a clinical vaginal cylinder and the cylinder generated using stereolithography were 1.29 ± 0.06 g/cm(3) vs 1.28 ± 0.01 g/cm(3), respectively. The mean measured dose from a representative stereolithographed applicator normalized to dose measured for a single plastic catheter was 99.8 ± 4.2%. In patient dosimetric results indicate improved coverage of the lateral aspect of vaginal vault with the custom cylinder relative to the standard cylinder; 700 cGy vs 328 cGy, respectively, at a representative lateral vaginal dose point, while simultaneously achieving relatively narrow dose distribution in the anterior/posterior direction. Stereolithographic applicator production was available within a clinically acceptable timeframe, and its clinical feasibility and utility has been demonstrated.

    Vaginal leiomyoma is a rare solid tumour of unknown aetiology, which usually develops in women between the ages of 35 and 50. As it presents with a wide range of symptoms, diagnosis is based on histological findings. Here we present the case of a 27-year-old white woman with a painless vaginal mass associated with dyspareunia, dysmenorrhea and foul-smelling vaginal discharge. She underwent surgery by vaginal route, and the histological findings confirmed a myxoid leiomyoma. After 17 months, the patient was disease-free, and symptoms disappeared. Vaginal leiomyomas are rare, local recurrence and transformation into sarcoma are rare, and complete surgical excision as soon as possible is recommended.

Concentration of IL-1beta in vaginal contents of women during bacterial vaginosis and normocenosis was determined by using enzume immunoassay. Changes of growth characteristics and biofilm formation ability of Staphylococcus aureus, Escherichia coli, Lactobacilus spp., Corynebacterium spp. under the effect of various IL-1beta concentrations by method of O'Toole G.A. (1999) were studied. IL-1beta in concentrations characteristic for normocenosis was shown to be able to cause stimulating effect on growth properties of lactobacilli and corynebacteria and suppress growth of S. aureus and E. coli in both plankton and biofilm cultures. IL-1beta concentrations characteristic for vaginal dysbiosis on the contrary result in suppression of growth of lactobacilli biomass against the background of stimulation of growth properties and biofilm formation ability of S. aureus and E. coli. Differential dose-dependent effect of IL-1beta on biomass growth and biofilm formation ability of vaginal microsymbionts is a mechanism of regulation of vaginal microbiocenosis.

    Is self-assessed vaginal pH measurement to detect abnormal vaginal bacterial microflora (AVF) an adequate prescreening method for detection of genital sexually transmitted infections (STIs)? A total of 360 Ugandan women tested themselves with a gloved finger and a pH color strip. PCR for bacterial vaginosis (BV)-associated bacteria was tested by PCR for Mycoplasma hominis, Ureaplasma urealyticum, and/or Atopobium vaginae, while the STIs were diagnosed by positive PCR for Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, and/or Trichomonas vaginalis. A strong correlation was found between self-assessed pH values and BV-associated bacteria (P<0.0001), but not with STIs, not as single infections, nor in general. Self-measured vaginal pH correlated well with markers of high-risk microflora types such as BV or aerobic vaginitis, but not with STIs. Hence, in a screening program addressing AVF in low-resource countries, extra specific tests are required to exclude STIs. Copyright © 2015 Elsevier Inc. All rights reserved.

    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

    Background: One of the variables most consistently associated with vaginal douching is race, with African-American women douching more regularly. Sparse data exists in the medical literature about the practice of vaginal douching among adolescents. The purpose of this study was to assess the prevalence, knowledge, attitude, and practices of vaginal douching among adolescent females attending a public family planning clinic, and determine whether African-American (AA) females douche to a greater degree than Caucasian females.Methods: In this cross-sectional study, a one-page questionnaire was administered to all adolescent females (vaginal douching, mostly for hygienic reasons (68%). Those reporting vaginal douching were more likely to have a history of one or more sexually transmitted diseases (O.R. 3. 7, 95% C.I. 1.5-9.0, p < 0.01). Age of first douche correlated positively with age of first sexual intercourse (r = 0.34, p < 0. 001). African-Americans did not douche to a greater degree than Caucasians. Among those who douched, AA females were more likely than Caucasians to believe that the reason women douche was after a period (p < 0.01) and after sex (p < 0.05), and to agree that douching clears up a discharge (p < 0.05) and odor (p < 0.01) from the vagina. Caucasians were more likely than AA to believe that some discharge from the vagina is normal (p < 0.05), and most women never need to douche (p < 0.01).Conclusions: Vaginal douching was a common practice among adolescent females

    Purpose: A fiducial tracking system based on a novel radioactive tracking technology is being developed for real-time target tracking in radiation therapy. In this study, the authors calculate the radiation dose to the patient, the spouse/caretaker, and the medical staff that would result from a 100 {mu}Ci Ir192 radioactive fiducial marker permanently implanted in the prostate of a radiation therapy patient. Methods: Local tissue dose was calculated by Monte Carlo simulation. The patient's whole body effective dose equivalent was calculated by summing the doses to the sensitive organs. Exposure of the spouse/caretaker was calculated from the NRC guidelines. Exposure ofmore » the medical staff was based on estimates of proximity to and time spent with the patient. Results: The local dose is below 40 Gy at 5 mm from the marker and below 10 Gy at 10 mm from the marker. The whole body effective dose equivalent to the patient is 64 mSv. The dose to the spouse/caretaker is 0.25 mSv. The annual exposures of the medical staff are 0.2 mSv for a doctor performing implantations and 0.34 mSv for a radiation therapist positioning patients for therapy. Conclusions: The local dose is not expected to have any clinically significant effect on the surrounding tissue which is irradiated during therapy. The dose to the patient is small in comparison to the whole body dose received from the therapy itself. The exposure of all other people is well below the recommended limits. The authors conclude that there is no radiation exposure related contraindication for use of this technology in the radiation treatment of prostate cancer.« less

  15. Trimethylamine content in vaginal secretion and its relation to bacterial vaginosis.

    The presence of a fishy odor emanating from women who present with a malodorous vaginal discharge is well known. The odor is due to bacterial reduction of trimethylamine oxide to trimethylamine (TMA) in vaginal secretion. The release of TMA from specimens of vaginal fluid following the addition of alkali is often used in making a clinical diagnosis of bacterial vaginosis (BV). We now report a sensitive gas chromatographic method for analysis and quantification of TMA in vaginal fluid in which weighed samples were used. In addition, a proper diagnosis of BV was obtained using Gram-stained smears of the vaginal fluid according to the method of Nugent et al. (R. P. Nugent et al., J Clin Microbiol 1991;29:297-301). We also diagnosed BV according to Hallén et al. (A. Hallén et al. Genitourin Med 1987;63:386-9). TMA was present in all women with a Nugent score between 7 and 10 and in almost all women diagnosed with BV according to the method of Hallén et al. TMA was not found or was only found in very low concentrations in vaginal fluid from women with Nugent scores of 0 to 3. TMA was also found in four women with a negative sniff test. It seems that high levels of TMA in samples of vaginal fluid are typical for BV regardless of the scoring method used for diagnosis. However, low levels of TMA, <5 microg/g vaginal fluid, do not always correlate with BV.

    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

    Bacterial cells in the human body account for 1-3% of total body weight and are at least equal in number to human cells. Recent research has focused on understanding how the different bacterial communities in the body (eg, gut, respiratory, skin, and vaginal microbiomes) predispose to health and disease. The microbiota of the reproductive tract has been inferred from the vaginal bacterial communities, and the uterus has been classically considered a sterile cavity. However, while the vaginal microbiota has been investigated in depth, there is a paucity of consistent data regarding the existence of an endometrial microbiota and its possible impact in reproductive function. This study sought to test the existence of an endometrial microbiota that differs from that in the vagina, assess its hormonal regulation, and analyze the impact of the endometrial microbial community on reproductive outcome in infertile patients undergoing in vitro fertilization. To identify the existence of an endometrial microbiota, paired samples of endometrial fluid and vaginal aspirates were obtained simultaneously from 13 fertile women in prereceptive and receptive phases within the same menstrual cycle (total samples analyzed n = 52). To investigate the hormonal regulation of the endometrial microbiota during the acquisition of endometrial receptivity, endometrial fluid was collected at prereceptive and receptive phases within the same cycle from 22 fertile women (n = 44). Finally, the reproductive impact of an altered endometrial microbiota in endometrial fluid was assessed by implantation, ongoing pregnancy, and live birth rates in 35 infertile patients undergoing in vitro fertilization (total samples n = 41) with a receptive endometrium diagnosed using the endometrial receptivity array. Genomic DNA was obtained either from endometrial fluid or vaginal aspirate and sequenced by 454 pyrosequencing of the V3-V5 region of the 16S ribosomal RNA (rRNA) gene; the resulting sequences were

    The aim of the study was to examine the dose enhancement from scattered radiation at bone-dental implant interfaces during simulated head and neck radiotherapy. Four cylindrical titanium dental implants with 3 different sizes and lengths were implanted into a human mandible in 4 different positions. Ionization measurements for 6 MV X, 25 MV X, and Co-60 gamma rays were done. Thermoluminescent dosimeter (TLD 100 ) chips were used to measure radiation dose enhancement due to the scattered electrons from titanium and electronic disequilibrium at the tissue-metal interface. The results showed that for Co-60, there is a 21% maximum increase in dose to alveolar mandibular bone at the close proximity to the titanium. For 6-MV x-rays the dose enhancement increase was almost the same or slightly lower than for Co-60, while for 25-MV high-energy x-rays, dose enhancement was lower than that of others. This increase in dose enhancement fell off rapidly and became insignificant at 2 mm from the interface. Total dose that may lead to osteoradionecrosis risk of the mandible is slightly but not significantly affected by the scattered dose of the dental implants of lower jaw in the radiation field exposed to 3 different radiation beams.

    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. 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/H(2)O, n = 4) as release media. For PK evaluation, SEVRs were inserted into adult female macaques (n = 6) for 30 days. Following a 1 week washout period, fresh rings were placed in the same animals, which were then challenged vaginally with RT-SHIV162P3 once weekly for 4 weeks. SEVRs released 1.66 and 101 mg of MC1220 into SVF and IPA/H(2)O, 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). Kaplan-Meier analysis over 9 weeks showed significantly lower infection rates for animals given MC1220-containing SEVRs than placebo rings (hazard ratio 0.20, P = 0.0037). 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.

    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.

  3. The role of lactobacilli and probiotics in maintaining vaginal health.

    The vaginal microbiota of healthy women consists typically of a diversity of anaerobic and aerobic microorganisms. Lactobacilli are the most prevalent and often numerically dominant microorganisms and are relevant as a barrier to infection. The capacity of lactobacilli to adhere and compete for adhesion sites in the vaginal epithelium and the capacity to produce antimicrobial compounds (hydrogen peroxide, lactic acid, bacteriocin-like substances), are important in the impairment of colonization by pathogens. This review summarizes the role of lactic acid bacteria in preventing illness of the host, including bacterial vaginosis, yeast vaginitis, urinary tract infection and sexually transmitted diseases. The administration of probiotics that colonize the vaginal tract can be important in maintaining a normal urogenital health and also to prevent or treat infections.

    Purpose: To investigate the current status of clinical usage of cochlear implant (CI) and other bionic devices (BD) in the brain and head and neck regions (BH and N) and their management in patients during radiotherapy to ensure patient health and safety as well as optimum radiation delivery. Methods: Literature review was performed with both CIs and radiotherapy and their variants as keywords in PubMed, INSPEC and other sources. The focus was on CIs during radiotherapy, but it also included other BDs in BHȦN, such as auditory brainstem implant, bionic retinal implant, and hearing aids, among others. Results: Interactions betweenmore » CIs and radiation may cause CIs malfunction. The presence of CIs may also cause suboptimum dose distribution if a treatment plan was not well designed. A few studies were performed for the hearing functions of CIs under irradiations of 4 MV and 6 MV x-rays. However, x-rays with higher energies (10 to 18 MV) broadly used in radiotherapy have not been explored. These higher energetic beams are more damaging to electronics due to strong penetrating power and also due to neutrons generated in the treatment process. Modern CIs are designed with more and more complicated integrated circuits, which may be more susceptible to radiation damage and malfunction. Therefore, careful management is important for safety and treatment outcomes. Conclusion: Although AAPM TG-34, TG-63, and TG-203 (update of TG-34, not published yet) reports may be referenced for management of CIs and other BDs in the brain and H and N regions, a site- and device-specified guideline should be developed for CIs and other BDs. Additional evaluation of CI functions under clinically relevant set-ups should also be performed to provide clinicians with better knowledge in clinical decision making.« less

    Radiation damage and its transformation under annealing were studied with bright-field and high-resolution transmission electron microscopy for arsenic-implanted HgCdTe films with graded-gap surface layers. In addition to typical highly defective layers in as-implanted material, a 50 nm-thick sub-surface layer with very low defect density was observed. The main defects in other layers after implantation were dislocation loops, yet after arsenic activation annealing, the dominating defects were single dislocations. Transport (from depth to surface), transformation and annihilation of radiation-induced defects were observed as a result of annealing, with the depth with the maximum defect density decreasing from 110 to 40 nm.

    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.

  7. Vaginal microbiome and sexually transmitted infections: an epidemiologic perspective

    PubMed Central

    2011-01-01

    Vaginal bacterial communities are thought to help prevent sexually transmitted infections. Bacterial vaginosis (BV) is a common clinical syndrome in which the protective lactic acid–producing bacteria (mainly species of the Lactobacillus genus) are supplanted by a diverse array of anaerobic bacteria. Epidemiologically, BV has been shown to be an independent risk factor for adverse outcomes including preterm birth, development of pelvic inflammatory disease, and acquisition of sexually transmitted infections. Longitudinal studies of the vaginal microbiome using molecular techniques such as 16S ribosomal DNA analysis may lead to interventions that shift the vaginal microbiota toward more protective states.

    Vaginal infections are a frequent cause for consultation, but their prevalence and etiology vary in different populations. To determine the prevalence and etiologies of vaginal infection in women attending a family health center in the Metropolitan Region of Chile. The microbiological diagnosis was made by wet mount and Gram stain. Diagnosis of trichomoniasis was performed by wet mount, culture and polymerase chain reaction. 101 women aged 15-54, not selected by signs or symptoms of vaginal infection, 46 of them pregnant were included. In 47 women (46.5%), vaginal infections were diagnosed. An association was observed between age and frequency of vaginal infection. The proportion of infections among pregnant and non-pregnant women was similar. The most frequent infections were bacterial vaginosis (16.8%), vulvovaginal candidiasis (11.9%) and co-infections (6.9%). We found 5.9% of intermediate microbiota cases, 3% of trichomoniasis and 2% of aerobic vaginitis. Symptoms of vaginal infection had poor agreement with microbiological findings. Otherwise physical signs had good agreement with the presence of infection, but low to moderate concordance with a specific etiology. We found a high prevalence of vaginal infections in the study population. It is necessary to improve the definitions and criteria of microbiological diagnosis of co-infections and intermediate microbiota, for them to be diagnosed in the clinical practice. More descriptive questionnaires are recommended to enhance the usefulness of clinical examination.

  9. A Lactobacillus-Deficient Vaginal Microbiota Dominates Postpartum Women in Rural Malawi

    2018-01-01

    ABSTRACT The bacterial community found in the vagina is an important determinant of a woman's health and disease status. A healthy vaginal microbiota is associated with low species richness and a high proportion of one of a number of different Lactobacillus spp. When disrupted, the resulting abnormal vaginal microbiota is associated with a number of disease states and poor pregnancy outcomes. Studies up until now have concentrated on relatively small numbers of American and European populations that may not capture the full complexity of the community or adequately predict what constitutes a healthy microbiota in all populations. In this study, we sampled and characterized the vaginal microbiota found on vaginal swabs taken postpartum from a cohort of 1,107 women in rural Malawi. We found a population dominated by Gardnerella vaginalis and devoid of the most common vaginal Lactobacillus species, even if the vagina was sampled over a year postpartum. This Lactobacillus-deficient anaerobic community, commonly labeled community state type (CST) 4, could be subdivided into four further communities. A Lactobacillus iners-dominated vaginal microbiota became more common the longer after delivery the vagina was sampled, but G. vaginalis remained the dominant organism. These results outline the difficulty in all-encompassing definitions of what a healthy or abnormal postpartum vaginal microbiota is. Previous identification of community state types and associations among bacterial species, bacterial vaginosis, and adverse birth outcomes may not represent the complex heterogeneity of the microbiota present. (This study has been registered at ClinicalTrials.gov as NCT01239693.) IMPORTANCE A bacterial community in the vaginal tract is dominated by a small number of Lactobacillus species, and when not present there is an increased incidence of inflammatory conditions and adverse birth outcomes.

    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

    Herein we report the case of a patient with primary amenorrhea and cyclic menouria. The patient was a 20-year-old woman with primary amenorrhea and inability to achieve sexual intercourse. Clinical examination revealed normally developed labia majora and minora, clitoris, and external urethral orifice, but no vaginal opening. A mature female pubic hair pattern was present, and axillary hair development was normal. Breasts were normally developed. Abdominopelvic magnetic resonance imaging demonstrated a remnant upper vagina and unicornuate uterus filled with fluid, and left-sided renal agenesis. Intraoperatively, a congenital vesicouterine fistulous tract was observed. The fistulous tract was completely resected. Vaginal reconstruction using a sigmoid colon pedicled flap was performed. The proximal part of the neovagina was connected to the remnant cervix, and a Foley catheter was left in the uterine cavity for 7 days to prevent obstruction. The patient has been menstruating regularly since the operation. Menouria might be an early sign of congenital vesicouterine fistula. Resection of the fistulous tract with uterine preservation might be considered in patients with vaginal agenesis. Copyright © 2011 AAGL. Published by Elsevier Inc. All rights reserved.

    Healthy vaginal microbiota is an important biological barrier to pathogenic microorganisms. When this predominantly Lactobacillus community is disrupted, decreased in abundance and replaced by different anaerobes, bacterial vaginosis (BV) may occur. BV is associated with prevalence and incidence of several sexually transmitted infections. This review provides background on BV, discusses the epidemiologic data to support a role of altered vaginal microbiota for acquisition of sexually transmitted diseases and analyzes mechanisms by which lactobacilli could counteract sexually transmitted viral infections.

    Objectives Vaginal douching is widely practiced by American women, particularly among minority groups, and is associated with increased risk of pelvic and vaginal infections. This research sought to investigate vaginal hygiene practices and meaning associated with them among Latina women and adolescents. Study results would guide development of an intervention to decrease douching among Latinas. Methods In depth qualitative interviews conducted with English- and Spanish-speaking women aged 16–40, seeking care for any reason who reported douching within the last year (n = 34). Interviews were audiotaped, transcribed and analyzed using qualitative methods. One-third of interviews were conducted in Spanish. Results Two explanatory models for douching motives emerged: one stressed cosmetic benefits; the other, infection prevention and control. Most women reported douching to eliminate menstrual residue; a small number reported douching in context of sexual intercourse or vaginal symptoms. Many were unaware of associated health risks. Respondents typically learned about douching from female family members and friends. Male partners were described as having little to no involvement in the decision to douche. Women varied in their willingness to stop douching. Two-thirds reported receiving harm reduction messages about “overdouching”. About half indicated previous discussion about douching with health care providers; some had reduced frequency in response to counseling. A number of previously unreported vaginal hygiene practices and products were described, including use of a range of traditional hygiene practices, and products imported from outside the US. Conclusions Respondents expressed a range of commitment to douching. Counseling messages acknowledging benefits women perceive as well as health risks should be developed and delivered tailored to individual beliefs. Further research is needed to assess prevalence and safety of previously unreported practices

    An appropriate representation of the tumor microenvironment in tumor models can have a pronounced impact on directing combinatorial treatment strategies and cancer nanotherapeutics. The present study develops a novel 3D co-culture spheroid model (3D TNBC) incorporating tumor cells, endothelial cells and fibroblasts as color-coded murine tumor tissue analogs (TTA) to better represent the tumor milieu of triple negative breast cancer in vitro. Implantation of TTA orthotopically in nude mice, resulted in enhanced growth and aggressive metastasis to ectopic sites. Subsequently, the utility of the model is demonstrated for preferential targeting of irradiated tumor endothelial cells via radiation-induced stromal enrichment of galectin-1 using anginex conjugated nanoparticles (nanobins) carrying arsenic trioxide and cisplatin. Demonstration of a multimodal nanotherapeutic system and inclusion of the biological response to radiation using an in vitro/in vivo tumor model incorporating characteristics of tumor microenvironment presents an advance in preclinical evaluation of existing and novel cancer nanotherapies. Existing in-vivo tumor models are established by implanting tumor cells into nude mice. Here, the authors described their approach 3D spheres containing tumor cells, enodothelial cells and fibroblasts. This would mimic tumor micro-environment more realistically. This interesting 3D model should reflect more accurately tumor response to various drugs and would enable the design of new treatment modalities. Copyright © 2015 The Authors.

    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) = 7–10 or ≥3 Amsel's criteria and NS = 4–10], 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 7–10) 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 18–50 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 7–10) 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 0.15–1.22) and 0.75 (95% CI 0.32–1.76) in the MTZ-Clind and MTZ-Prob groups compared to MTZ-Plac respectively. Cumulative 6-month BV recurrence was 28.2%; (95%CI 24.0–32.7%) 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 = 0.70–1.70) and 1.03(95% CI = 0.65–1

    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.

    Vacuum and forceps assisted vaginal deliveries are reported to increase the incidence of postpartum infections and maternal readmission to hospital compared to spontaneous vaginal delivery. Prophylactic antibiotics may be prescribed to prevent these infections. However, the benefit of antibiotic prophylaxis for operative vaginal deliveries is still unclear. To assess the effectiveness and safety of antibiotic prophylaxis in reducing infectious puerperal morbidities in women undergoing operative vaginal deliveries including vacuum or forceps deliveries, or both. We searched Cochrane Pregnancy and Childbirth's Trials Register (12 July 2017), ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (12 July 2017) and reference lists of retrieved studies. All randomised trials comparing any prophylactic antibiotic regimens with placebo or no treatment in women undergoing vacuum or forceps deliveries were eligible. Participants were all pregnant women without evidence of infections or other indications for antibiotics of any gestational age undergoing vacuum or forceps delivery for any indications. Interventions were any antibiotic prophylaxis (any dosage regimen, any route of administration or at any time during delivery or the puerperium) compared with either placebo or no treatment. Two review authors assessed trial eligibility and methodological quality. Two review authors extracted the data independently using prepared data extraction forms. Any discrepancies were resolved by discussion and a consensus reached through discussion with all review authors. We assessed methodological quality of the one included trial using the GRADE approach. One trial, involving 393 women undergoing either vacuum or forceps deliveries, was included. The trial compared the antibiotic intravenous cefotetan after cord clamping compared with no treatment. This trial reported only two out of the nine outcomes specified in this review. Seven women in the group

    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 healthcare resources. The Women in the Military Self-Diagnosis (WMSD) and treatment kit was developed as a field-expedient solution to this problem. The primary study aims were to evaluate the accuracy of women's self-diagnosis of vaginal symptoms and eight diagnostic algorithms and to predict potential self-medication omission and commission error rates. Participants included 546 active duty, deployable Army (43.3%) and Navy (53.6%) women with vaginal symptoms who sought healthcare 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 [BV] and/or trichomonas vaginitis [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. Women's 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 value of diagnostic algorithms ranged from 0% to 78.1% for BV/TV and 41.7% for CV. The algorithms were based on clinical diagnostic standards. The nonspecific 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

    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 to 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.

    2012-01-01

    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.

    To investigate the vaginal flora in patients with recurrent vulvovaginal candidiasis (RVVC). Vaginal swabs were collected at different time points from 6 RVVC patients and 5 healthy women of child-bearing age. The dynamic changes, microbiota composition, alpha diversity and beta diversity in the two groups were assessed by analyzing the 16S rRNA V4 hypervariable region amplified from the total genomic DNA from the swabs. Lactobacillus was the predominant species in healthy women with similar proportions of L.iners and L.crispatus; small proportions of Gardnerella, Prevotella and other genus were also detected. In some healthy women, the vaginal flora showed a high relative abundance of anaerobic bacteria such as Gardnerella, Prevotella, Atopobium, Sneathia. Compared with the healthy women, patients with RVVC showed a significantly reduced diversity of vaginal flora, where L.iners was the predominant species and the content of L.crispatus decreased significantly. In healthy women, the vaginal flora fluctuated with the menstrual cycle, and the fluctuation was the most prominent during menstruation; the dominant species either alternated regularly or maintain an absolute superiority in the menstrual cycle. The vaginal flora showed attenuated fluctuation in women with RVVC, were highly conserved within the menstrual cycle, and maintained a similar composition in the episodes and intermittent periods. The vaginal flora of RVVC patients do not undergo regular variations with the menstrual cycle and shows a similar composition between the episodes and intermittent periods. Promoting the production of L.iners or inhibiting the colonization of L.crispatus to restore the composition of the vaginal flora may help in the treatment of RVVC.

    Vaginal suppositories frequently used in gynaecological therapy were studied. Several antibacterial pharmacons are used for the topical treatment of vaginitis of various origins. In view of the fact that the liberation of the given active substance and the subsequent therapeutic effect may be improved or inhibited by the vehicle, our aim was to find the optimal suppository base for vaginal suppositories containing sulfadimidine, chloramphenicol and gentamicin sulfate by means of in vitro experiments. On the basis of breaking hardness, disintegration time and spreading properties the French Suppocire NA product, and compositions of macrogols with lower molecular weight proved to be the best lipophilic and hydrophilic bases, respectively. Among the lipophilic bases the in vitro drug liberation of Suppocire NA was significantly better (P < 0.05) than the other lipophilic bases. This vehicle is recommended for the topical treatment of vaginitis, as these suppositories have the further advantage that they can easily be produced on a magistral, galenical or industrial scale as well.

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.

    In patients with posthysterectomy prolapse of the vaginal vault, the posterior intravaginal slingplasty (posterior IVS, Tyco Healthcare, USA) has been suggested as an alternative to traditional vaginal vault suspensions. The goal of this technique is to recreate the uterosacral ligaments and to reinforce the rectovaginal fascia with the use of prosthetic material. We report the case of a 53-year-old woman with a history of 27 months of perineal suppurative discharge after she underwent a vaginal vault prolapse and rectocele repair using a posterior IVS (Tyco Healthcare, USA). The IVS tape was reinforced by interposing a rectovaginal monofilament polypropylene mesh (Parietex, Sofradim, France). Imaging studies and surgical exploration confirmed infection of the IVS mesh with the formation of a gluteo-vaginal fistula while the rectovaginal mesh was intact.

    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.

    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). Kaplan–Meier 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

However, studies using an estrogen-dependent murine model of vaginal candidiasis have demonstrated little to no change in resident vaginal T cells during infection and no systemic T-cell infiltration despite the presence of Candida-specific systemic Th1-type responses in infected mice. The present study was designed to further investigate these observations by characterizing T-cell activation and cell adhesion molecule expression during primary and secondary C. albicans vaginal infections. While flow cytometry analysis of activation markers showed some evidence for activation of CD3+ draining lymph node and/or vaginal lymphocytes during both primary and secondary vaginal Candida infection, CD3+ cells expressing the homing receptors and integrins α4β7, αM290β7, and α4β1 in draining lymph nodes of mice with primary and secondary infections were reduced compared to results for uninfected mice. At the local level, few vaginal lymphocytes expressed integrins, with only minor changes observed during both primary and secondary infections. On the other hand, immunohistochemical analysis of vaginal cell adhesion molecule expression showed increases in mucosal addressin cell adhesion molecule 1 and vascular cell adhesion molecule 1 expression during both primary and secondary infections. Altogether, these data suggest that although the vaginal tissue is permissive to cellular infiltration during a vaginal Candida infection, the reduced numbers of systemic cells expressing the reciprocal cellular adhesion molecules may preempt cellular infiltration, thereby limiting Candida-specific T-cell responses against infection.

    It remains uncertain whether clinical factors known prior to delivery can predict which women are more likely to experience shoulder dystocia in the setting of operative vaginal delivery. We sought to identify whether shoulder dystocia can be accurately predicted among women undergoing an operative vaginal delivery. This was a case-control study of women undergoing a low or outlet operative vaginal delivery from 2005 through 2014 in a single tertiary care center. Cases were defined as women who experienced a shoulder dystocia at the time of operative vaginal delivery. Controls consisted of women without a shoulder dystocia at the time of operative vaginal delivery. Variables previously identified to be associated with shoulder dystocia that could be known prior to delivery were abstracted from the medical records. Bivariable analyses and multivariable logistic regression were used to identify factors independently associated with shoulder dystocia. A receiver operating characteristic curve was created to evaluate the predictive value of the model for shoulder dystocia. Of the 4080 women who met inclusion criteria, shoulder dystocia occurred in 162 (4.0%) women. In bivariable analysis, maternal age, parity, body mass index, diabetes, chorioamnionitis, arrest disorder as an indication for an operative vaginal delivery, vacuum use, and estimated fetal weight >4 kg were significantly associated with shoulder dystocia. In multivariable analysis, parity, diabetes, chorioamnionitis, arrest disorder as an indication for operative vaginal delivery, vacuum use, and estimated fetal weight >4 kg remained independently associated with shoulder dystocia. The area under the curve for the generated receiver operating characteristic curve was 0.73 (95% confidence interval, 0.69-0.77), demonstrating only a modest ability to predict shoulder dystocia before performing an operative vaginal delivery.

    Background We sought to establish a nonhuman primate model of vaginal Lactobacillus colonization suitable for evaluating live microbial microbicide candidates. Methods Vaginal and rectal microflora in Chinese rhesus macaques (Macaca mulatta) were analyzed, with cultivable bacteria identified by 16S rRNA gene sequencing. Live lactobacilli were intravaginally administered to evaluate bacterial colonization. Results Chinese rhesus macaques harbored abundant vaginal Lactobacillus, with Lactobacillus johnsonii as the predominant species. Like humans, most examined macaques harbored only one vaginal Lactobacillus species. Vaginal and rectal Lactobacillus isolates from the same animal exhibited different genetic and biochemical profiles. Vaginal Lactobacillus was cleared by a vaginal suppository of azithromycin, and endogenous L. johnsonii was subsequently restored by intravaginal inoculation. Importantly, prolonged colonization of a human vaginal Lactobacillus jensenii was established in these animals. Conclusions The Chinese rhesus macaque harbors vaginal Lactobacillus and is a potentially useful model to support the pre-clinical evaluation of Lactobacillus-based topical microbicides.

    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. 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. 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, 3(2) full factorial design was employed. Optimized batch showed in vitro disintegration time, 18 min; drug content, 99.83%; and tensile strength, 502.1 g/mm(2). 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. Mucoadhesive vaginal film of CT is an effective dosage form for the treatment of vaginal candidiasis.

    To evaluate levels of proinflammatory cytokines and sialidase activity in aerobic vaginitis (AV) in relation to normal vaginal flora and bacterial vaginosis (BV). In this cross-sectional study, a total of 682 consecutive non-pregnant women attending the gynecology service were assessed and 408 women were included. Vaginal rinsing samples were collected from 223 women with microscopic finding of BV (n=98), aerobic vaginitis (n=25) and normal flora (n=100). Samples were tested for interleukin (IL)-1β, IL-6, IL-8, tumor necrosis factor (TNF)-α, and sialidase activity. Compared to women with normal flora, vaginal levels of IL-1β were highly increased in both BV and AV (p<0.0001). Significantly higher vaginal IL-6 was detected in AV (p<0.0001) but not in BV, in relation to normal flora. Women with AV also presented increased IL-8 levels (p<0.001), while those with BV presented levels similar to normal flora. Sialidase was increased in BV and AV compared with the normal group (p<0.0001) but no difference in sialidase activity was observed between BV and AV. A more intense inflammatory host response occurs for AV than for BV when compared with normal flora. Furthermore, the increased sialidase activity in AV and BV indicates that both abnormal vaginal flora types can be harmful to the maintenance of a healthy vaginal environment.

    To report the usual postoperative course and complications after pull-through vaginoplasty for isolated distal vaginal atresia. Retrospective chart review at Texas Children's Hospital of all patients who were diagnosed with isolated distal vaginal atresia and underwent pull-through vaginoplasty during the study time frame. None. Postoperative complications such as vaginal stenosis or infection and postoperative vaginal diameter. Sixteen patients were identified and charts were reviewed. Patients were initially evaluated by pelvic magnetic resonance imaging and found to have distended hematometrocolpos with distal vaginal atresia. All patients underwent pull-through vaginoplasty with similar operative techniques. The average distance from the perineum to the level of the obstruction was 1.84 ± 1.2 cm. Two patients, both with obstructions at greater than 3 cm, experienced stricture formation postoperatively. Four patients (25%) experienced postoperative vaginitis. One patient (6.25%) experienced a postoperative urinary tract infection. Two groups (3 cm or less versus greater than 3 cm) were compared, and the presence of stricture was statistically different based on mean centimeters from perineum prior to pull-through vaginoplasty (P = .038). Distal vaginal atresia is managed with pull-through vaginoplasty. Atresias that extend greater than 3 cm from the perineum are at increased risk for vaginal stricture formation and should be followed to monitor for their formation. Other complications are infrequent and minor. Copyright © 2015 North American Society for Pediatric and Adolescent Gynecology. Published by Elsevier Inc. All rights reserved.

    We evaluated levels of vaginal extracellular matrix metalloproteinase inducer (EMMPRIN) and matrix metalloproteinase (MMP-8) in vaginal secretions in relation to the composition of vaginal bacterial communities and D- and L-lactic acid levels. The composition of vaginal bacterial communities in 46 women was determined by pyrosequencing the V1 to V3 region of 16S rRNA genes. Lactobacilli were dominant in 71.3% of the women, followed by Gardnerella (17.4%), Streptococcus (8.7%), and Enterococcus (2.2%). Of the lactobacillus-dominated communities, 51.5% were dominated by Lactobacillus crispatus, 36.4% by Lactobacillus iners, and 6.1% each by Lactobacillus gasseri and Lactobacillus jensenii. Concentrations of L-lactic acid were slightly higher in lactobacillus-dominated vaginal samples, but most differences were not statistically significant. D-Lactic acid levels were higher in samples containing L. crispatus than in those with L. iners (P<0.0001) or Gardnerella (P=0.0002). The relative proportion of D-lactic acid in vaginal communities dominated by species of lactobacilli was in concordance with the proportions found in axenic cultures of the various species grown in vitro. Levels of L-lactic acid (P<0.0001) and the ratio of L-lactic acid to D-lactic acid (P=0.0060), but not concentrations of D-lactic acid, were also correlated with EMMPRIN concentrations. Moreover, vaginal concentrations of EMMPRIN and MMP-8 levels were highly correlated (P<0.0001). Taken together, the data suggest the relative proportion of L- to D-lactic acid isomers in the vagina may influence the extent of local EMMPRIN production and subsequent induction of MMP-8. The expression of these proteins may help determine the ability of bacteria to transverse the cervix and initiate upper genital tract infections. A large proportion of preterm births (>50%) result from infections caused by bacteria originating in the vagina, which requires that they traverse the cervix. Factors that influence
