Dendritic cells pulsed with a recombinant chlamydial major outer membrane protein antigen elicit a CD4(+) type 2 rather than type 1 immune response that is not protective.

Chlamydia trachomatis is an obligate intracellular bacterium that infects the oculogenital mucosae. C. trachomatis infection of the eye causes trachoma, the leading cause of preventable blindness. Infections of the genital mucosae are a leading cause of sexually transmitted diseases. A vaccine to prevent chlamydial infection is needed but has proven difficult to produce by using conventional vaccination approaches. Potent immunity to vaginal rechallenge in a murine model of chlamydial genital infection has been achieved only by infection or by immunization with dendritic cells (DC) pulsed ex vivo with whole inactivated organisms. Immunity generated by infection or ex vivo antigen-pulsed DC correlates with a chlamydia-specific interleukin 12 (IL-12)-dependent CD4(+) Th1 immune response. Because of the potent antichlamydial immunizing properties of DC, we hypothesized that DC could be a powerful vehicle for the delivery of individual chlamydial antigens that are thought to be targets for more conventional vaccine approaches. Here, we investigated the recombinant chlamydial major outer membrane protein (rMOMP) as a target antigen. The results demonstrate that DC pulsed with rMOMP secrete IL-12 and stimulate infection-sensitized CD4(+) T cells to proliferate and secrete gamma interferon. These immunological properties implied that rMOMP-pulsed DC would be potent inducers of MOMP-specific CD4(+) Th1 immunity in vivo; however, we observed the opposite result. DC pulsed ex vivo with rMOMP and adoptively transferred to naive mice generated a Th2 rather than a Th1 anti-MOMP immune response, and immunized mice were not protected following infectious challenge. We conclude from these studies that the immunological properties of ex vivo pulsed DC are not necessarily predictive of the immune response generated in vivo following adoptive transfer. These findings suggest that the nature of the antigen used to pulse DC ex vivo influences the Th1-Th2 balance of the immune response in vivo.

Colpocleisis for the treatment of vaginal vault prolapse.

Most females with total vault prolapse undergo reconstructive procedures to restore normal anatomy and function; however, elderly patients who no longer desire sexual intercourse or are medically unstable can be treated effectively with a vaginal closure or colpocleisis. The traditional approach to colpocleisis has been to simply invert the vagina using pursestring sutures after removing the vaginal mucosa. Although simple to perform, after repairing referred treatment failures who used this approach, we began to use a different approach that emphasizes the strength of an anterior repair and extensive posterior repair that then is sutured together. This vaginal closure is reinforced with a strong perineorrhaphy. This multicompartment colpocleisis was performed in 38 elderly females (mean age 77, range 68 to 88) with total vault prolapse. No treatment failures were noted with a mean follow-up of 24 months (range 3 to 52 months), and all patients were satisfied with the results of the procedure. No significant complications occurred, and no patient has regretted the loss of sexual function. The aim of this article is to discuss the indications, procedural aspects, and results of performing a multicompartment colpocleisis and partial colpocleisis for total vault prolapse in elderly females.

Histologic correlates of papillomavirus infection of the vagina.

Vaginal warts (condylomata) secondary to human papillomavirus (HPV) infection are most easily identified when perinuclear halos are seen with clear-cut nuclear atypia (koilocytotic atypia) in the superficial cells of the lesion. However, vaginal lesions clinically resembling condylomata may exhibit lesser degrees of nuclear atypia with findings suggestive of, but not typical for, the presence of HPV. The diagnosis and management of such lesions are unclear. We correlated histologic findings with the detection of HPV DNA sequences in 39 vaginal lesions that contained a spectrum of clinical and histologic features suggestive of, or diagnostic for, condyloma. We detected HPV DNA in 63% (N = 22) of lesions with koilocytotic atypia and in 11.7% (N = 17) of lesions that showed some histologic features suggesting condyloma but that lacked koilocytotic atypia. These findings imply that vaginal lesions lacking koilocytotic atypia are not always caused by HPV, emphasizing the need for a conservative approach when the diagnosis of vaginal condyloma is not clear-cut.

Surgical management of urethrovaginal and vesicovaginal fistulas.

This report reviews a 50 year period during which 157 vesico- and 24 urethrovaginal fistulas were managed. Although the etiologic factors have changed, there has not been a dramatic decrease in the incidence of this complication. In the last 17 years we have noted an increased number of both types of fistula, primarily related to the increased frequency of gynecologic operative procedures. Only 11 (6%) of the fistulas reported in this series resulted from surgical procedures performed in our department. In this series 96% were repaired vaginally but the abdominal approach was used for certain complicated fistulas. Our initial cure rate was 89% and the final success rate in 157 vesicovaginal fistulas was 94.3%. The urethrovaginal fistulas represent a special problem because of the location, scarring, and lack of sufficient fascia for a second-layer closure. In such instances we have successfully used the bulbocavernous fat pad. The success rate for 24 patients with this type of fistula was 87.5%.

Vesicouterine fistulas following cesarean section: report on a case, review and update of the literature.

Herein we report on 1 more case of vesicouterine fistula following cesarean section with review and update of the literature concerning this unusual topic. The disease presented with vaginal urinary leakage, cyclic hematuria and amenorrhea. The fistula was successfully repaired by delayed surgery. Actually, all over the world the prevalence of the disease is increasing for the frequent use of the cesarean section. Fistulas may develop immediately after a cesarean section, manifest in the late puerperium or occur after repeated procedures. Spontaneous healing is reported in 5% of cases. Vesicouterine fistulas present with vaginal urinary leakage, cyclic hematuira (menouria), amenorrhea, infertility, and first trimester abortions. The diagnosis is ruled out by showing the fistulous track between bladder and uterus as well as by excluding other more frequent urogenital fistulas. The disease treatment options include conservative treatment as well as surgical repair. Rarely, patients refuse any kind of treatment because of the benignity of symptoms and prognosis of the disease. Conservative management by bladder catheterization for at least 4-8 weeks is indicated when the fistula is discoveredjust after delivery since there is good chance for spontaneous closure of the fistulous track. Hormonal management should be tried in women presenting with Youssef's syndrome. Surgery is the maninstay and definitive treatment of vesicouterine fistulas after cesarean section. Patients scheduled for surgery should undergo pretreatment of urinary tract infections. Surgical repair of vesico-uterine fistulas are performed by different approaches which include the vaginal, transvesical-retroperitoneal and transperitoneal access which is considered the most effective with the lowest relapse rate. Recently, laparoscopy has been proposed as a valid option for repairing vesicouterine fistulas. The endoscopic treatment may be effective in treating small vesicouterine fistulas. The pregnancy rate after repair is 31.25% with a rate of term deliveries of 25%. The disease may be prevented by emptying the bladder as well as by carefully dissecting the lower uterine segment. It is advisable that after vesicouterine fistula repair delivery should be performed by repeating a cesarean section since the risk of fistula recurrence. Usually, vesicouterine fistulas are diagnosed postoperatively. As a result, at least 95% of patients will undergo another operation for repairing the fistula. In the meantime they are bothered by related symptoms which impair their quality of life. As far as we are concerned intraoperative diagnosis is the gold standard in detecting vesicouterine fistulas for allowing immediate repair. We propose intraoperative sonography by the transvaginal (or transrectal) route for the Foley transurethral catheter producing bloody urine, for suspecting bladder injury while dissecting the uterine lower segment and for monitoring patients who already had had vesicouterine fistula repair. As a result patients will avoid the familial and social problems related to the disease as well another operation. Moreover, ultrasound Doppler examination may help in better investigating and understanding the pathophysiology of vesicouterine fistulas.

Abnormal vaginal bleeding in perimenopausal women.

The incidence of abnormal vaginal bleeding increases as women approach the end of their reproductive years. In the perimenopausal age group, the most common cause of abnormal vaginal bleeding is anovulation. In most patients, diagnosis and management can be accomplished in a family physician's office.

Effect of lactobacilli administration in the vaginal tract of mice: evaluation of side effects and local immune response by local administration of selected strains.

Lactobacilli are the predominant microorganisms in the vaginal tract of human and some homeothermic animals. They can maintain the ecological equilibrium of the tract by protecting against pathogenic microorganisms. In the last few years, there has been an increased tendency to use probiotic microorganisms to restore the ecological equilibrium and to protect against infections. This principle has been widely applied to the gastrointestinal tract. More recently, some other studies have reported the application of probiotics in different tracts, for example, the urogenital or respiratory tract. One of the objectives of our group is to design probiotic products for the urogenital tract. With this purpose, lactobacilli were isolated from the human vagina, and later some of them were selected for their probiotic characteristics (production of antagonistic substances or adhesion capability). The application of probiotic products in the vaginal tract has been approached empirically; some pharmaceuticals containing these microorganisms are available in the United States or Europe or are protected under the patent process or intellectual property rights. There are not enough studies in humans or animals to determine whether their administration can produce some type of collateral or adverse effect. Using Balb/c mice as the experimental model, the object of the present work was to study (1) whether intravaginal administration of human lactobacilli can produce colonization of the tract; (2) whether such administration produces some type of adverse or collateral effect; and (3) whether probiotics are able to stimulate the local immune system. Keeping in mind that hormones can affect the colonization or persistence ability of microorganisms, and with the purpose of having all animals at the same point in the sexual cycle, animals were cycled with estradiol 48 h before inoculation with lactobacilli. They were then inoculated im with hormones 48 h before beginning microorganism inoculations. Later they were intravaginally inoculated with the appropriate dose of each Lactobacillus strains. The animals were sacrificed on different days after inoculation to perform the following studies: 1. Microbiological assays: To determine the number of lactobacilli in the tract (in vaginal washes or in organ homogenates), by plating the samples in selective media containing antibiotic (to differentiate the resident flora from those administered experimentally).

Patient selection and surgical technique may reduce major complications of laparoscopic-assisted vaginal hysterectomy.

STUDY OBJECTIVE: To study the clinical outcome of patients who underwent laparoscopic-assisted vaginal hysterectomy especially with regard to early postoperative complications. DESIGN: Retrospective study (Canadian Task Force classification II-3). SETTING: Private hospital in Hamilton, New Zealand. PATIENTS: Four hundred eighteen women. INTERVENTION: Laparoscopic-assisted vaginal hysterectomy. MEASUREMENTS AND MAIN RESULTS: Primary indication for surgery, operating time, hospital stay, and major complications were analyzed. Major complications were defined as life-threatening injuries, unintended major surgical procedures, and conversions to laparotomy that occurred under duress (eg, intraoperative hemorrhage). Complications were reported up to 6 weeks of postoperative time. The total early postoperative complication rate was 11.24%. No patient had damage to the bowel, ureter, or bladder. There were no deaths. Major complications were three cases of partial vault dehiscence and one case of partial small bowel obstruction. The operation was performed successfully in 412 cases. Six patients needed laparotomy. CONCLUSIONS: This retrospective study shows that laparoscopic-assisted vaginal hysterectomy is a safe surgical procedure. The possible reasons for the low complication rate reported are the surgical technique of ureteral dissection, the use of suitable instruments to expose the vaginal fornices, a consistent team approach, and the selection of patients.

Syndromic management of vaginal discharge and pelvic inflammatory disease among women in a rural community of Haryana, India: agreement of symptoms enquiry with clinical diagnosis.

World Health Organisation (1984) advocated syndromic approach for management of reproductive tract infections/sexually transmitted diseases. Some investigators have cautioned against using this approach to diagnose and treat vaginal discharge and pelvic inflammatory disease. The prevalence of RTIs in rural areas of Haryana is high and availability of per-speculum examination facility is scarce. The scope for laboratory diagnosis of RTI in rural areas is remote in near future. A community-based study was conducted to assess the agreement of symptoms enquiry with the syndromic diagnosis of RTIs/STDs (based upon per speculum examination). A total of 812 women were interviewed by ANMs and were examined by a lady doctor. History based ANM's diagnosis was found to be having high sensitivity (80.5%) and high positive predictive value (81.3%). However it had low specificity (48.6%) and low negative predictive value (47.5%) compared to clinical diagnosis. Level of agreement was found to be fair (Kappa = 0.28, 95% CI = 0.20-0.36). The chances of over treatment for vaginal discharge and pelvic inflammatory disease were only 16% and 15% respectively. However, history based syndromic protocols need revision. Proposed protocol is discussed in this paper.

Paraurethral leiomyoma--an imitator.

In location and clinical appearance a paraurethral leiomyoma imitated other disease in 2 patients. Correct preoperative diagnosis of these lesions can avert therapeutic error. Diagnostic clues include a solid, noncystic mass that does not communicate with the urethra, is circumscribed, and has essentially normal overlying mucosa. A surgical approach through the anterior vaginal wall avoids urethral injury and enucleation is curative.

Transobturator tape sling for female stress incontinence with polypropylene tape and outside-in procedure: prospective study with 1 year of minimal follow-up and review of transobturator tape sling.

OBJECTIVES: To assess the efficacy and safety of a minimally invasive surgical procedure using a polypropylene transobturator tape to treat female stress urinary incontinence during a minimal follow-up of 1 year and to present a review of this technique. METHODS: A total of 206 women with stress urinary incontinence who underwent the transobturator tape procedure in a French multicenter prospective open tracker study, with a minimal follow-up of 1 year (range 12 to 33 months), were assessed. A nonelastic, polypropylene tape was placed under the mid-urethra. The surgical placement technique used a vaginal and transobturator percutaneous approach. Postoperative assessments included clinical examination, cough-stress test (full bladder), uroflowmetry, and postvoid residual urine volume performed after 1, 6, 12, 18, and 24 months. RESULTS: The mean follow-up was 16 months (range 12 to 33). Of the 206 patients, 79.1% were completely cured, 13% improved, and 7% failed. No vascular, nervous system, or digestive perioperative complications were observed; however, 2.4% of the patients had postoperative urinary retention. CONCLUSIONS: The results of the present study have confirmed the optimal results in stress incontinence previously reported in short-term studies. These results suggest that the transobturator tape procedure is a valuable alternative to the transvaginal tape procedure, with a low rate of complications.

Radiation injury to intestine following hysterectomy and adjuvant radiotherapy for cervical cancer.

OBJECTIVE: To evaluate the risk factors for nonrectal radiation-induced intestinal injury (NRRIII) following adjuvant radiotherapy (RT) for cervical cancer using a retrospective review of medical records. METHODS: From September 1992 to December 1998, 164 patients with uterine cervical cancer that had completed their allocated adjuvant radiotherapy at the Chinese Medical University Hospital were enrolled for NRRIII analysis. The patients were classified into two groups according to the extent of surgery. Group A consisted of 110 patients (International Federation of Gynecology and Obstetrics [FIGO] stage: IB, n = 87; IIA, n = 21; IIB, n = 2) undergoing radical hysterectomy and bilateral pelvic lymph node dissection, while Group B was composed of 54 analogs receiving adjuvant radiotherapy following incident extrafascial hysterectomy. Treatment consisted of external beam radiotherapy (EBRT) and high-dose-rate intravaginal brachytherapy (HDRIVB). Initially, the whole pelvis was treated with 10 MV X-rays. After irradiation (44 Gy in 22 fractions over 4-5 weeks), the field was limited to the true pelvis and a further 10-20 Gy delivered in 5-10 fractions. For 21 patients in group A without pelvic lymph node metastasis or lymphovascular invasion, the radiation field was confined to the lower pelvis, with a prescribed dose of 50-58 Gy delivered over 5-6 weeks. HDRIVB was performed using an Ir-192 remote after-loading technique at 1-week intervals. A total of 159 patients (97%) received two insertions, while 5 had only one. The standard prescribed HDRIVB dose was 7.5 Gy to the vaginal surface. Logistic regression analysis was performed for assessment of the factors associated with NRRIII. RESULTS: After 38-119 months of follow-up (median, 60), 22 patients (13.4%) developed Radiation Therapy Oncology Group (RTOG) grade 2 or greater NRRIII at a median latency of 18 months (range, 5-48). Four patients were diagnosed as grade 3 complications requiring surgery and three had expired. The independent factors for NRRIII were radical hysterectomy (P = 0.04, relative risk 2.45), lower-pelvic dose >54 Gy (P = 0.0001, relative risk 10.27), and age over 60 years (P = 0.001, relative risk 5.45). The incidence of NRRIII for patients receiving whole and lower-pelvic irradiation was 14.5% and 10.6%, respectively (P = 0.45). Although there was no statistical significance comparing the two external beam irradiation strategies in terms of NRRIII, all four patients with grade 3 NRRIII underwent whole pelvic irradiation. CONCLUSION: This study identifies three predictive factors for the development of NRRIII following adjuvant radiotherapy for cervical cancer. Limiting the EBRT dose to less than 54 Gy, meticulous patient selection in the elderly, careful planning of the irradiated field, and the constraint of vaginal brachytherapy are four approaches to optimization of postoperative adjuvant radiotherapy.

A simpler approach to labor induction using lipid-based prostaglandin E2 vaginal suppository.

The outcome of labor induced by use of a glyceride-based vaginal suppository of prostaglandin E2 (PGE2) inserted 3 hours before amniotomy, when the cervix is favorable, has been assessed. Using 5 mg PGE2 for primigravidas and 2.5 mg for multigravidas, 63% of the former and 81% of the latter established labor and were delivered of their infants without oxytocin augmentation, allowing ambulation during early labor. No maternal complications were detected as a result of the PGE2 treatment. Compared with patients undergoing conventional induction by amniotomy and immediate oxytocin titration there was no difference in the duration of labor, with a few patients establishing labor and giving birth quickly with both induction methods. Fetal distress was less common following PGE2 treatment than following conventional induction, with three patients in each group requiring delivery by cesarean section. Cephalopelvis disproportion in the second stage of labor requiring cesarean section to deliver occurred more frequently in the prostaglandin-treated group, possibly as a result of reduced upper segment contractility in the first stage of labor with subsequent poor fetal head molding. Epidural analgesia and postpartum hemorrhge were both reduced following PGE2-induced labor.

Evaluation of the bacterial vaginal flora of 20 postmenopausal women by direct (Nugent score) and molecular (polymerase chain reaction and denaturing gradient gel electrophoresis) techniques.

To monitor the bacterial vaginal microflora of postmenopausal women, several approaches were used: (1) Nugent scoring of Gram-stained smears from vaginal swabs; (2) testing for bacteria, using specific polymerase chain reaction (PCR) primers; (3) PCR-denaturing gradient gel electrophoresis (DGGE) analysis of total bacterial DNA, amplified using eubacterial and Lactobacillus-specific primers; and (4) sequence analysis of amplified DNA fragments of interest from denaturing gradient gels. Of 20 women studied, 70% had either intermediate-grade bacterial colonization or bacterial vaginosis (BV), as defined by Nugent criteria, at the first sampling point. Subjects with normal Nugent scores had >/=1 species of Lactobacillus detected by sequencing of dominant DNA fragments from denaturing gradient gels generated using eubacterial primers. Samples from women with Nugent scores that indicated BV had varied bacterial DGGE profiles, which emphasizes the diverse nature of such infections. This study indicates that asymptomatic BV appears to be much more common than is currently perceived; these findings may have implications for the health of postmenopausal women.

Sonographic techniques in human in-vitro fertilization programmes.

The value of ultrasound in programmes of in-vitro fertilization is discussed. In order to reach the ovaries, the transvesical route was first introduced, and proved less invasive than laparoscopy. The periurethral route has also been used. The transvaginal approach, especially using a vaginal transducer with an attached needle guide, has attracted many IVF groups and is widely used today. Details of this method are presented. Ultrasound has also been used to assist in the replacement of embryos into the uterus, and the various methods are described.

Vaginal evisceration after hysterectomy: a literature review.

The purpose of this review is to highlight the risk factors, clinical presentation, and different surgical management options for vaginal evisceration after vaginal, abdominal, or laparoscopic hysterectomy. We identified all reports of vaginal evisceration after these procedures using sources in the literature from 1900 to the present. We found that a total of 59 patients were reported, 37 (63%) had a prior vaginal hysterectomy, 19 (32%) had a prior abdominal hysterectomy (2 of which were radical hysterectomy), and 3 (5%) had a prior laparoscopic hysterectomy. The majority of these patients were postmenopausal women. Also, the precipitating event was most often sexual intercourse in premenopausal patients and increased intra-abdominal pressure in postmenopausal patients. In addition, the small bowel was the most common organ to eviscerate. Most of the patients presented with vaginal bleeding, pelvic pain, or a protruding mass. We conclude that vaginal evisceration after hysterectomy remains a rare event. It is more often seen after vaginal hysterectomy than after other types of hysterectomy. It can also occur spontaneously or following trauma or vaginal instrumentation, or any event that increases intra-abdominal pressure. Vaginal evisceration represents a surgical emergency, and the approach to therapy for it may be abdominal, vaginal or a combination of the two.
