Capsule types of Klebsiella pneumoniae isolated from the genital tract of mares with metritis, extra-genital sites of healthy mares and the genital tract of stallions.

A survey of K. pneumoniae was performed on cervical swabs, feces and nasal swabs of mares and on samples from the genital tract of stallions from 1980 to 1986 in south-western Hokkaido, Japan. K1 was the predominant type (79 of 88, 89.8%) in the metritis cases due to K. pneumoniae in mares of racing breeds. The same type was isolated from semen and swabs of the fossa glandis of 6 of 20 (30.0%) of the stallions of racing breeds. Heavily encapsulated and less heavily encapsulated K1 strains were isolated from the stallions. Mares bred to stallions carrying heavily encapsulated strains developed metritis, while those bred to stallions carrying less heavily encapsulated strains did not. K39 was isolated from cervical swabs solely from metritis-infected mares of draft breeds and not from any mares of the racing breeds examined. Untypable strains were isolated from cervical swabs in 7 of 88 (8.0%) metritis cases of mares of racing breeds and from semen in 7 of 19 (36.8%) stallions of racing breeds and they were predominant in feces (19 of 21, 90.5%) and nasal swabs (3 of 4, 75.0%) of healthy mares of racing breeds.

Factors predicting upper genital tract inflammation among women with lower genital tract infection.

We sought to identify factors that discriminate between women with a lower genital tract infection and women with a lower genital tract infection and endometritis. This study enrolled women at risk for or having a lower genital tract infection with Chlamydia trachomatis or Neisseria gonorrhoeae and measured behavioral and clinical factors. Women were identified through contact tracing of male partners, presentation with cervicitis, or presentation with symptoms of pelvic inflammatory disease and classified as (1) having a lower genital tract infection without endometritis, (2) having a lower genital tract infection with endometritis, (3) having no lower genital tract infection with endometritis, and (4) having neither a lower genital tract infection nor endometritis. The primary comparison was between women having a lower genital tract infection without endometritis to women having a lower genital tract infection and endometritis. Women with a lower genital tract infection and endometritis were older and reported a history of more sexually transmitted diseases (70.0% vs. 56.7%), abdominal pain (82.2% vs. 60.0%), and use of barrier methods of contraception (28.9% vs. 8.6%) than women with a lower genital tract infection alone. The regression model found that women with a lower genital tract infection and endometritis were 7.1 times (95% CI = 2.2-23.0) more likely to report abdominal pain and 4.6 times (95% CI = 1.5-14.9) more likely to use barrier methods of contraception than women with a lower genital tract infection alone. These results suggest that behavioral factors, in addition to symptoms, can be used to identify women with and without upper genital tract involvement.

Integrated health research program for the Thai elderly: prevalence of genital prolapse and effectiveness of pelvic floor exercise to prevent worsening of genital prolapse in elderly women.

BACKGROUND: Genital prolapse is a common health problem in elderly women. It is prevalent among elderly females and affects their quality of life. Those with a severe degree of genital prolapse may need operative treatment which may be risky due to co-morbid conditions such as hypertension, respiratory disease, cardiovascular disease and diabetes mellitus. The aim of this study was to determine the prevalence of genital prolapse and the effectiveness of pelvic floor exercise to prevent worsening of genital prolapse in elderly females. METHOD: The authors conducted a cross sectional study to determine the prevalence of genital prolapse in 682 elderly women (aged > or = 60 years) who lived within a 10-kilometer radius of Siriraj Hospital. 654 subjects were eligible for the controlled trial to determine the effectiveness of pelvic floor exercise to prevent worsening of genital prolapse. There were 324 subjects in the control group and 330 subjects in the experimental group. The experimental group received training in pelvic floor exercise and were asked to perform the exercise 30 times after one meal, every day for 24 months. The subjects were followed-up every 6 months for 24 months to assess worsening of genital prolapse. RESULTS: The prevalence of genital prolapse was 70 per cent. There were 324 subjects in the control group and 330 subjects in the experimental group. After 24 months of pelvic floor exercise, the rate of worsening of genital prolapse was 72.2 per cent in the control group and 27.3 per cent in the experimental group (p = 0.005). The rate of worsening of genital prolapse was not significantly different between the control group and the study group in those who had a mild degree of genital prolapse. CONCLUSION: The prevalence of genital prolapse in elderly Thai women was 70 per cent. A 24 months pelvic floor exercise program was effective to prevent worsening of genital prolapse in the women who had severe genital prolapse.

Human genital papilloma infections: an evaluation of immunologic competence in the genital neoplasia-papilloma syndrome.

Immunologic evaluations of women with genital neoplasia-papilloma syndrome demonstrated the presence of subclinical immunodeficiency when compared with results in 20 control women. All patients with genital neoplasia-papilloma syndrome were previously found to have human papillomavirus deoxyribonucleic acid in genital neoplasias or papillomas occurring either synchronously (in at least two genital organs at the same time) or metachronously (at different times during a period of months to years). Immunologic tests included blastogenic responses of lymphocytes to mitogens (phytohemagglutinin, concanavalin A, pokeweed mitogen, and tetanus antigen) and lymphocyte phenotyping with the use of monoclonal antibodies (OKT3, OKT4, OKT8, and OKT11). As compared with those of control subjects, the responses of the lymphocytes of patients with genital neoplasia-papilloma syndrome to mitogens were significantly decreased. The group with genital neoplasia-papilloma syndrome had a significantly higher percentage of suppressor-cytotoxic T cells (OKT8-positive cells) when compared with that of control subjects (mean 33% versus 18%) and a lower proportion of helper T cells (OKT4-positive cells) when compared with that of control subjects (35% versus 50%). The mean helper-to-suppressor/cytotoxic T-cell ratio (mean OKT4/OKT8 ratio) in the human papillomavirus-infected women was 1.72 +/- 0.29 (SE) as compared with 3.21 +/- 0.33 (SE) in the control group, demonstrating a significant reduction of the ratio in the patients with genital neoplasia-papilloma syndrome. These findings suggest that patients with genital neoplasia-papilloma syndrome have a reduced suppressor/cytotoxic T-cell ratio (mean OKT4/OKT8 ratio; that in the human papillomavirus-infected women was 1.72 +/- 0.29 (SE) as compared with 3.21 +/- 0.33 (SE) in the control group, demonstrating a significant reduction of the ratio in patients with genital neoplasia-papilloma syndrome. These findings suggest that patients with genital neoplasia-papilloma syndrome have reduced immunocompetence of unknown etiology.

The high prevalence of genital herpes among patients with genital ulcer disease in Uganda.

BACKGROUND: Genital ulcer disease is a risk factor for transmission of human immunodeficiency virus. One-hundred consecutive Ugandan patients (median age, 25 years) with genital ulcer disease were examined to determine the prevalence of genital herpes and its relationship to human immunodeficiency virus seropositivity. GOAL OF THIS STUDY: To improve management, prevention, and control of genital ulcer disease, thus reducing human immunodeficiency virus infections attributable to genital ulcer disease. STUDY DESIGN: This was a prevalence study of genital herpes in a consecutive sample of an urban sexually transmitted disease clinic population. RESULTS: Forty-nine percent (48/98) of the patients had genital herpes (36% by direct fluorescent antigen and 13% by history of recurrent vesicles). There was a trend toward larger lesions in patients who were human immunodeficiency virus seropositive. Twelve percent (11/89) of patients had syphilis, and 30% (30/100) remained sexually active, despite the presence of active genital ulcer disease. Sixty-five percent of 89 patients tested had antibodies to human immunodeficiency virus. CONCLUSIONS: Genital herpes is a common cause of genital ulcer disease in patients attending sexually transmitted disease clinics in Uganda, and herpes ulcers may be more extensive among those who are infected with human immunodeficiency virus.

Susceptibility to reinfection after a primary chlamydial genital infection is associated with a decrease of antigen-specific T cells in the genital tract.

We tested the hypothesis that the intensity of specific antichlamydial T cell-mediated immunity in the genital tract of female guinea pigs infected intravaginally with the chlamydial agent of guinea pig inclusion conjunctivitis would determine the resistance or susceptibility to reinfection after a primary chlamydial infection. T cell-enriched lymphocytes were isolated by collagenase treatment of genital tract tissues from either infected or control uninfected female guinea pigs at various times after infection. The nylon wool-enriched T lymphocytes were evaluated for expression of antigen-specific T cell-mediated immunity in vitro by using a blast transformation assay. Both uninfected and infected genital tracts contained T cells, as evidenced by reactivity to concanavalin A, although a greater number of T lymphocytes was detected in the genital tracts of infected animals compared with that in controls. Significant antigen-specific T-cell activity could be detected in the genital tract tissue by 7 days after a primary genital tract infection with the chlamydial agent of guinea pig inclusion conjunctivitis. When antigen-specific activity was assessed at different times after infection, the intensity of the response of genital tract-associated T lymphocytes was directly proportional to the degree of resistance of the animals to genital challenge. Thus, susceptibility of animals to reinfection by chlamydiae appears to be associated with the intensity of the local T cell-mediated immune responses in the genital tract of infected animals.

Hand-genital transmission of genital warts? An analysis of prevalence data.

The role of hand-genital transmission in the aetiology of genital warts is unclear. However this route is suggested by a number of observations including the relatively high proportion of genital warts in children which contain HPV types 1-4 (15% for children and 2% for adults). We compared two transmission models; one which assumes that hand-genital transmission occurs and one that it does not, and determined the conditions in which each model can reflect the available prevalence data. Hand-genital transmission provides a simple explanation of the observed differences in the proportions of genital warts containing HPV types 1-4 and 6/11 in children and adults. If hand-genital transmission does not occur, the observed difference could only be explained by an eightfold greater probability of transmission to children of types 1-4 than types 6/11, or by an eightfold greater duration of infection with types 1-4. Our findings provide support for the view that genital warts may be transmitted by hand-genital contact.

[Genital herpes simplex virus infection among men screened for genital papillomavirus].

OBJECTIVE: Our aim was to assess the frequency of herpetic genital infection (HSV) among men attending a human papillomavirus (HPV) screening centre. Clinical screening of a herpetic lesion was completed with biological detection of HSV by cell culture and by polymerase chain reaction (PCR). We also evaluated the role of the male viral factor on the female partners. METHOD: We performed a genital examination by colposcopy of 135 men whose female partners presented an HPV genital infection. The HPV lesions detected underwent biopsy by Southern blot viral analysis. The lesions which clinically appeared to be caused by HSV were removed for HSV detection and typing by cell culture and by PCR. Sperm was collected for viral detection by cell culture and PCR was collected for viral detection by cell culture and PCR from patients presenting a herpetic type urethral symptomatology. RESULTS: Peniscopy detected HPV lesions in 46 p. 100 of the men, in 88 p. 100 of cases in the balano-preputial zone and in 82 p. 100 of cases their morphology was exophytic. The other areas were in 14.5 p. 100 of cases urethral and 9 p. 100 anal. We detected a dysplasic lesion in 6 p. 100 of cases. In 74 p. 100 of cases molecular hybridization by Southern detected 6/11/42 type HPV and in 6.4 p. 100 of cases HPV 16. Clinical examination revealed the presence of genital herpetic infection in 15.5 p. 100 of cases, of these 76 p. 100 were preputial and 24 p. 100 meato-urethral. PCR detected HSV-2 in 88 p. 100 of the preputial lesions and in 86 p. 100 of the spermatic ejaculates from the meato-urethral lesions. The chi 2 test showed that no link exists between a herpetic genital infection and the presence of an HPV lesion, but that the risk is greater (OR = 2.15; IC 95 p. 100 = 0.84-5.49). We also observed that 50 p. 100 of the female partners of men with both HPV+HSV infections had high grade cervical lesions. CONCLUSION: This study shows that clinical examination in an HPV screening centre enabled detection of clinical HSV in 15.5 p. 100 of cases as opposed to 17 p. 100 biologically. Thus the good clinical-virological correlation shows that clinical criteria remain the principal elements for detecting viral genital infections, it therefore appears advantageous to only use the new HSV identification techniques for targeted detection. Also, herpetic genital infection is independent of human papillomavirus infection. When screening for HPV, herpetic genital infection should be taken into account as we have observed that the female partners of men with both HPV + HSV are at greater risk of presenting high grade cervical lesions.

Genital vascular responsiveness and sexual feelings in midlife women: psychophysiologic, brain, and genital imaging studies.

The incidence of women's experiences of lack of sexual arousal increases in the years around the natural menopause transition. This raises the questions to what extent are sexual complaints in postmenopausal women related to hormonal changes, and what is the contribution of psychologic and contextual factors to sexual function in this transitional phase of life. This article reviews all published evidence regarding (1) the relation between menopausal status and sexual arousal symptoms, (2) the extent to which these sexual symptoms relate to measured genital vascular responses to sexual stimuli, and (3) the correlation between women's genital vascular response and their experience of subjective sexual arousal. Psychophysiologic and preliminary functional magnetic resonance imaging (MRI) studies of increases in genital congestion in response to erotic stimulation fail to identify differences between premenopausal and postmenopausal women. This suggests that although urogenital aging results in changes in anatomy and physiology of the genitals, postmenopausal women preserve their genital responsivity when sufficiently sexually stimulated. The vaginal dryness and dyspareunia experienced by some postmenopausal women may result from longstanding lack of sexual arousal and protection from pain previously afforded by estrogen-related relatively high blood flow in the unaroused state. Psychophysiologic studies confirm similar increases in genital vasocongestion from erotic stimuli in women with and without chronically low sexual arousal, even in those women focusing specifically on their perceived lack of genital response. Moreover, studies repeatedly confirm highly variable correlations between subjective sexual arousal and measured increases in genital congestion.

Genotypic analysis of sequential genital herpes simplex virus type 1 (HSV-1) isolates of patients with recurrent HSV-1 associated genital herpes.

Clinical recurrences of Herpes simplex virus type 1 (HSV-1)-associated genital herpes are thought to be caused by reactivation of latent endogenous HSV-1. However, the possibility of reinfection with exogenous HSV-1 cannot be excluded. This study aimed to determine the incidence of genital HSV-1 superinfection in patients by investigating the genotype of sequential HSV-1 isolates obtained from the same anatomical site of patients with clinical recurrences of genital HSV-1 recurrent genital herpes. Sequential genital HSV-1 isolates were genotyped by PCR amplification of the hypervariable regions located within the HSV-1 genes US1 and US12. Whereas the sequential HSV-1 isolates in 11 of the 13 patients studied had the same genotypes, the sequential isolates of 2 patients showed a different genotype. The data suggest that HSV-1-induced recurrent genital herpes can be associated with genital reinfection with an exogenous HSV-1 strain.

Analysis of herpes simplex virus-specific T cells in the murine female genital tract following genital infection with herpes simplex virus type 2.

A murine model of genital infection with a thymidine kinase-deficient (tk-) strain of herpes simplex virus type 2 (HSV-2) was utilized to examine the development of the local T cell response in the genital mucosa and draining genital lymph nodes (gLN). HSV-specific cytokine-secreting T cells were detected in the gLN 4 days postintravaginal inoculation but not in the urogenital tract or spleen until 5 days postinoculation, suggesting the cellular immune response originates in the gLN. More CD4+ than CD8+ gLN T cells were detected by flow cytometric analysis following primary vaginal inoculation and the majority of HSV-specific gLN T cells detected by ELISPOT were CD4+ and Th1-like based on secretion of IFN gamma and not IL-4 or IL-5. A similar population of HSV-specific memory T cells persisted in the genital tract 2 months following HSV-2 tk- genital inoculation. These data suggest that the urogenital cellular immune response elicited in mice following genital inoculation with HSV-2 tk- is predominantly CD4+ and Th1-like, resembling that observed in humans. The results of this study are important for the rational design of vaccines capable of inducing protective immunity in the genital tract.

Amylases of the genital tract. I. Isoamylases of genital tract tissue homogenates and peritoneal fluid.

Homogenates of tissue from the female genital tract contain isoamylases which are, to a certain extent, electrophoretically distinguishable from the pancreatic and salivary isoamylases. In healthy nonpregnant women, high levels of activity of genital isoamylases were found in tissue homogenates of cervical and Fallopian tube mucosa, whereas activity was weak or absent in homogenates of endometrium. The isoamylases of the cervical mucosa had an electrophoretic migration rate toward the anode identical to that of the salivary main fraction, whereas the isoamylases of the Fallopian tube migrated faster. Specific genital isoamylase activities were also demonstrable in peritoneal fluid collected from the cul-de-sac. During the menstrual cycle, these activities showed a midcycle peak. In pregnant women, the levels of activity of the genital isoamylases in peritoneal fluid were lower than in nonpregnant women. In homogenates of the male accessory genital glands, the isoamylases specific for the genital tract were present in minute amounts. The isoamylases specific for the genital tract were not detectable in serum in either sex.

Oestrogen formation in genital and non-genital skin fibroblasts cultured from patients with hypospadias.

OBJECTIVE: Hypospadias is the most common birth defect in males. In most cases the aetiology is unknown. Since penile development is androgen dependent and oestrogen can modify androgen action, we compared the formation of oestrogen in penile tissue from patients with hypospadias to those with normal penile development. DESIGN AND PATIENTS: Oestrogen formation was assessed in fibroblast monolayers grown from biopsies of genital and non-genital skin from 11 males with normal genital development (controls) and 18 males with severe hypospadias utilizing the incorporation of tritium into H2O resulting from the aromatization of 1 beta-3H-androstenedione. RESULTS: In paired fibroblast strains from genital and non-genital skin of nine males with hypospadias, oestrogen formation was significantly (P < 0.025) lower in non-genital skin. Rates of oestrogen formation were also higher in a subset of foreskins from subjects with hypospadias than in normal controls and the remaining hypospadias subjects. In addition, oestrogen formation in this subset of fibroblast strains from patients with hypospadias was markedly enhanced by incubation of intact monolayers with either cholera toxin or forskolin, agents known to stimulate cAMP formation. Oestrogen formation in the remaining cell strains (controls and hypospadias) was also enhanced in most instances by cholera toxin and forskolin, although to a much lower degree. Thus, we identified in the hypospadias group a subgroup of fibroblast strains in which unstimulated and stimulated oestrogen formation was markedly higher than in other strains examined. CONCLUSIONS: Since oestrogen can modify certain androgen effects within cells and since formation of the male genitalia during embryogenesis is mediated by androgens, elevated oestrogen formation in male genital tissue might be a causative factor of hypospadias in some instances.

Genital warts: incidence of associated genital infections.

Two hundred and seventy-eight men and 200 women who presented to a Special Treatment Clinic with genital warts were screened for accompanying genital infections. One hundred and twenty-nine of 212 presentations (61%) in women compared to 98 of 303 presentations (32%) in men were accompanied by another genital infection P less than 0.001). Recurrent presentation with warts was commoner in men (P less than 0.001). In both sexes recurrences were less likely to be accompanied by another genital infection. (P less than 0.002). Yeasts (25%), C. vaginale (21%), N.gonorrhoea (12%) and T. vaginalis (12%) were the commonest pathogens in women. Non-specific genital infection (17%) and gonorrhoea (10%) were the commonest accompanying infections in men. The identification and treatment of these infections, especially in women, is important for the rapid eradication of warts, for, by increasing genital moisture they can create and maintain a favourable environment for wart proliferation. In addition to screening all patients with warts for other sexually transmitted diseases, women should be screened for yeasts and C. vaginale.

Oral famciclovir for the suppression of recurrent genital herpes: a randomized controlled trial. Collaborative Famciclovir Genital Herpes Research Group.

CONTEXT: Recurrent genital herpes simplex virus (HSV) may be treated episodically, but this may not be sufficient for patients with frequent recurrences. OBJECTIVE: To determine the efficacy and safety of famciclovir in the suppression of recurrent genital HSV infection. DESIGN: A randomized, double-blind, placebo-controlled, parallel-group study. SETTING: Thirty university, hospital, or private outpatient referral centers in Canada and Europe. PATIENTS: A total of 455 patients (223 men, 232 women) aged 18 years or older with a history of 6 or more episodes of genital herpes during 12 of the most recent 24 months, in the absence of suppressive therapy, received study medication. INTERVENTION: Oral famciclovir, 125 mg or 250 mg 3 times daily or 250 mg twice daily, or placebo for 52 weeks. MAIN OUTCOME MEASURES: Time to the first recurrence of genital HSV infection; the proportion of patients remaining free of HSV recurrence at 6 months; frequency of adverse events. RESULTS: In an intent-to-treat analysis, famciclovir significantly delayed the time to the first recurrence of genital herpes at all dose regimens (hazard ratios, 2.9-3.3; P<.001); median time to recurrence for famciclovir recipients was 222 to 336 days compared with 47 days for placebo recipients. The proportion of patients remaining free of HSV recurrence was approximately 3 times higher in famciclovir recipients (79%-86%) than in placebo recipients (27%) at 6 months (relative risks, 2.9-3.1; P<.001); efficacy was maintained at 12 months. Famciclovir was well tolerated with an adverse experience profile comparable to placebo. CONCLUSIONS: Oral famciclovir (125 mg or 250 mg 3 times daily or 250 mg twice daily) is an effective, well-tolerated treatment for the suppression of genital HSV infection in patients with frequent recurrences.

Specific effect of estradiol on the genital mucosal antibody response in chlamydial ocular and genital infections.

Estradiol treatment of female guinea pigs was found to alter the course of genital, but not ocular, infection with the chlamydial agent of guinea pig inclusion conjunctivitis. Immunoglobulin G (IgG) and IgA responses in genital secretions of genitally infected animals were delayed by estradiol treatment, but neither response in the eye resulting from either ocular or genital infection was affected. However, the appearance of IgG in the genital tract after ocular infection was markedly inhibited in estradiol-treated guinea pigs.

Genital reinfection after recovery from initial genital infection with herpes simplex virus type 2 in guinea pigs.

The natural history of genital reinfection with herpes simplex virus type 2 (HSV-2) three weeks to one year after initial infection was explored by using a guinea pig model. Intravaginal reinoculation with HSV-2 of animals that had recovered from initial genital infection produced by wild-type or thymidine kinase-deficient HSV-2 produced asymptomatic genital reinfection characterized by high-titered replication of HSV-2 in the vaginal vault. Reinoculation did not result in acute neural infection, as was seen during initial genital herpes, and no evidence of latent infection by the rechallenge strain could be demonstrated. The frequency of recurrences appeared to be established by the initial infection because reinfection did not alter the pattern of recurrent genital herpes. The present study suggest that asymptomatic reinfection may produce a reservoir of communicable virus and that initial infection with a less virulent mutant of HSV-2 may provide protection against subsequent reexposure to wild-type HSV-2.

Rate and predictors of new genital warts claims and genital warts-related healthcare utilization among privately insured patients in the United States.

BACKGROUND: Little non-clinic-based data are available on incident genital warts rates and related healthcare use. GOAL: : The goal of this study was to describe the incidence and predictors of genital warts and associated healthcare utilization patterns among a group of privately insured patients in the United States. STUDY: Health claims were evaluated prospectively from 5,914,107 privately insured individuals. RESULTS: The rate of new genital warts claims per 100,000 person-years at risk, age-standardized to the 2001 U.S. privately insured population, increased from 117.8 in 1998 to 205.0 in 2001. The highest rates were among 20- to 29-year-olds. The majority of claims came from dermatology and obstetrics/gynecology. CONCLUSIONS: The incidence of genital warts, as measured by the rate of new claims, appears to be rising. Age associations with the rate of new genital warts claims differed by gender; these associations may be influenced by changes in health-seeking behavior, potentially driven by health awareness.
