In Drosophila melanogaster, the intersex (ix) is a terminally positioned gene in somatic sex determination hierarchy and function with the female specific product of double sex (DSX(F)) to implement female sexual differentiation. The null phenotype of ix is to transform diplo-X individuals into intersexes while leaving haplo-X animals unaffected. This study on the effect of different intersex mutations on genital disc development provides the following major results: (i) similar range of a characteristic array of morphological structures (from almost double sex terminalia to extreme reduction of terminal appendages) was displayed by the terminalia of XX ix(1)/ix(1) , XX ix(2)/ix(2) and XX ix(5)/ix(5) individuals; (ii) an increased number of apoptotic cells were found to occur in a localized manner in mature third instar larval genital discs of ix individuals; (iii) ix mutations can induce high frequency of neoplastic tumours in genitals in the presence of decapentaplegic (dpp(disk)) mutations; and (iv) heteroallelic combinations of dpp(disk) mutations can also induce tumours in intersex genitals with variable expressivity. On the basis of these findings, we suggest that: (i) loss of function of ix causes massive cell death in both male and female genital primordia of genital discs, resulting phenotype mimicking in male and female characteristics in genitals; and (ii) at the discs, the apoptotic cells persist as 'undead' cells that can induce oncogenic transformation in the neighbouring disc cells when dpp signalling is blocked or reduced by dpp(disk) mutations.

We have recently reported that the sublingual (s.l.) mucosa is an efficient site for inducing systemic and mucosal immune responses. In this study, the potential of s.l. immunization to induce remote Ab responses and CD8(+) cytotoxic responses in the female genital tract was examined in mice by using a nonreplicating Ag, OVA, and cholera toxin (CT) as an adjuvant. Sublingual administration of OVA and CT induced Ag-specific IgA and IgG Abs in blood and in cervicovaginal secretions. These responses were associated with large numbers of IgA Ab-secreting cells (ASCs) in the genital mucosa. Genital ASC responses were similar in magnitude and isotype distribution after s.l., intranasal, or vaginal immunization and were superior to those seen after intragastric immunization. Genital, but not blood or spleen, IgA ASC responses were inhibited by treatment with anti-CCL28 Abs, suggesting that the chemokine CCL28 plays a major role in the migration of IgA ASC progenitors to the reproductive tract mucosa. Furthermore, s.l. immunization with OVA induced OVA-specific effector CD8(+) cytolytic T cells in the genital mucosa, and these responses required coadministration of the CT adjuvant. Furthermore, s.l. administration of human papillomavirus virus-like particles with or without the CT adjuvant conferred protection against genital challenge with human papillomavirus pseudovirions. Taken together, these findings underscore the potential of s.l. immunization as an efficient vaccination strategy for inducing genital immune responses and should impact on the development of vaccines against sexually transmitted diseases.

Squamous cell carcinoma (SCC) represents the most common malignant tumour of the eye and external genitals in horses. Comparable to humans, papillomaviruses (PV) have been proposed as etiological agents of cancer in horses and recently, Equine papillomavirus type 2 (EcPV2) has been identified in genital SCCs. Hitherto it had never been demonstrated in ocular SCCs. The first goal of this study was to determine the prevalence of EcPV2 DNA in tissue samples from equine genital and ocular SCCs, genital papillomas and penile intraepithelial neoplasia (PIN) lesions, using EcPV2-specific PCR. The second goal was to investigate the possibility of latent EcPV2 infection in the genital and ocular mucosa of healthy horses on swabs obtained from the eye, penis, vulvovaginal region and cervix. EcPV2 DNA was detected in all genital SCCs (17/17), genital papillomas (8/8), PIN lesions (11/11) and ocular SCCs (9/9). In healthy horses, EcPV2 DNA was detected in 43% (17/40) of penile swabs, 53% (9/17) of vulvovaginal swabs, 47% (8/17) of cervical swabs and 57% (32/56) of ocular swabs. This study confirms the presence of EcPV2 DNA in equine genital SCCs. Moreover, we demonstrate for the first time its involvement in other genital lesions and in ocular SCCs and latent EcPV2 infections in normal genital (including cervical) and ocular equine mucosa. The close relatives of EcPV2 are associated to cutaneous lesions, and this virus is not related to high-risk human papillomaviruses causing cervical cancer. Thus, similar viral tropism does not imply close evolutionary relationship. Copyright Â© 2010 Elsevier B.V. All rights reserved.

Stem cells are necessary to maintain tissue homeostasis and the microenvironment (a.k.a. the niche) surrounding these cells controls their ability to self renew or differentiate. For many stem cell populations it remains unclear precisely what cells and signals comprise a niche. Here we identify a possible PGC niche in the mouse genital ridges. Conditional ablation of Bmpr1a was used to demonstrate that BMP signaling is required for PGC survival and migration as these cells colonize the genital ridges. Reduced BMP signaling within the genital ridges led to increased somatic cell death within the mesonephric mesenchyme. Loss of these supporting cells correlated with decreased levels of the mesonephric marker, Pax2, as well as a reduction in genes expressed in the coelomic epithelium including the putative PGC chemo-attractants Kitl and Sdf1a. We propose that BMP signaling promotes mesonephric cell survival within the genital ridges and that these cells support correct development of the coelomic epithelium, the target of PGC migration. Loss of BMP signaling leads to the loss of the PGC target resulting in reduced PGC numbers and disrupted PGC migration. PMID:20417197

Human immunodeficiency virus (HIV)–infected leukocytes have been detected in genital secretions from HIV-infected men and women and may play an important role in the sexual transmission of HIV. However, they have been largely overlooked in studies on mechanisms of HIV transmission and in the design and testing of HIV vaccine and microbicide candidates. This article describes the characteristics and quantities of leukocytes in male and female genital secretions under various conditions and also reviews evidence for the involvement of HIV-infected cells in both horizontal and vertical cell-associated HIV transmission. Additional research is needed in this area to better target HIV prevention strategies. PMID:25414414

In mouse embryos at mid-gestation, primordial germ cells (PGCs) undergo licensing to become gametogenesis-competent cells (GCCs), gaining the capacity for meiotic initiation and sexual differentiation. GCCs then initiate either oogenesis or spermatogenesis in response to gonadal cues. Germ cell licensing has been considered to be a cell-autonomous and gonad-independent event, based on observations that some PGCs, having migrated not to the gonad but to the adrenal gland, nonetheless enter meiosis in a time frame parallel to ovarian germ cells -- and do so regardless of the sex of the embryo. Here we test the hypothesis that germ cell licensing is cell-autonomous by examining the fate of PGCs in Gata4 conditional mutant (Gata4 cKO) mouse embryos. Gata4, which is expressed only in somatic cells, is known to be required for genital ridge initiation. PGCs in Gata4 cKO mutants migrated to the area where the genital ridge, the precursor of the gonad, would ordinarily be formed. However, these germ cells did not undergo licensing and instead retained characteristics of PGCs. Our results indicate that licensing is not purely cell-autonomous but is induced by the somatic genital ridge. PMID:25739037

Schistosoma haematobium is a waterborne parasite that may cause female genital schistosomiasis (FGS), characterized by genital mucosal lesions. There is clinical and epidemiological evidence for a relationship between FGS and HIV. We investigated the impact of FGS on HIV target cell density and expression of the HIV co-receptor CCR5 in blood and cervical cytobrush samples. Furthermore we evaluated the effect of anti-schistosomal treatment on these cell populations. The study followed a case-control design with post treatment follow-up, nested in an on-going field study on FGS. Blood and cervical cytobrush samples were collected from FGS negative and positive women for flow cytometry analyses. Urine samples were investigated for schistosome ova by microscopy and polymerase chain reaction (PCR). FGS was associated with a higher frequency of CD14+ cells (monocytes) in blood (11.5% in FGS+ vs. 2.2% in FGS-, p = 0.042). Frequencies of CD4+ cells expressing CCR5 were higher in blood samples from FGS+ than from FGS- women (4.7% vs. 1.5%, p = 0.018). The CD14+ cell population decreased significantly in both compartments after anti-schistosomal treatment (p = 0.043). Although the frequency of CD4+ cells did not change after treatment, frequencies of CCR5 expression by CD4+ cells decreased significantly in both compartments (from 3.4% to 0.5% in blood, p = 0.036; and from 42.4% to 5.6% in genital samples, p = 0.025). The results support the hypothesis that FGS may increase the risk of HIV acquisition, not only through damage of the mucosal epithelial barrier, but also by affecting HIV target cell populations, and that anti-schistosomal treatment can modify this.

Pathogenic microorganisms, such as Neisseria gonorrhoeae, have developed mechanisms to alter epithelial barriers in order to reach subepithelial tissues for host colonization. The aim of this study was to examine the effects of gonococci on cell junction complexes of genital epithelial cells of women. Polarized Ishikawa cells, a cell line derived from endometrial epithelium, were used for experimental infection. Infected cells displayed a spindle-like shape with an irregular distribution, indicating potential alteration of cell-cell contacts. Accordingly, analysis by confocal microscopy and cellular fractionation revealed that gonococci induced redistribution of the adherens junction proteins E-cadherin and its adapter protein β-catenin from the membrane to a cytoplasmic pool, with no significant differences in protein levels. In contrast, gonococcal infection did not induce modification of either expression or distribution of the tight junction proteins Occludin and ZO-1. Similar results were observed for Fallopian tube epithelia. Interestingly, infected Ishikawa cells also showed an altered pattern of actin cytoskeleton, observed in the form of stress fibers across the cytoplasm, which in turn matched a strong alteration on the expression of fibronectin, an adhesive glycoprotein component of extracellular matrix. Interestingly, using western blotting, activation of the ERK pathway was detected after gonococcal infection while p38 pathway was not activated. All effects were pili and Opa independent. Altogether, results indicated that gonococcus, as a mechanism of pathogenesis, induced disruption of junction complexes with early detaching of E-cadherin and β-catenin from the adherens junction complex, followed by a redistribution and reorganization of actin cytoskeleton and fibronectin within the extracellular matrix.

A vaccine against heterosexual transmission by human immunodeficiency virus (HIV) should generate cytotoxic and antibody responses in the female genital tract and in extra-genital organs. We report that sublingual immunization with HIV-1 gp41 and a reverse transcriptase polypeptide coupled to the cholera toxin B subunit (CTB) induced gp41-specific IgA antibodies and antibody-secreting cells, as well as reverse transcriptase-specific CD8 T cells in the genital mucosa, contrary to intradermal immunization. Conjugation of the reverse transcriptase peptide to CTB favored its cross-presentation by human dendritic cells to a T cell line from an HIV(+) patient. Sublingual vaccination could represent a promising vaccine strategy against heterosexual transmission of HIV-1.

Using ultrasensitive polymerase chain reaction-based techniques, we assessed levels of cell-free and cell-associated human immunodeficiency virus (HIV)-1 in paired blood and genital samples of 30 clinically asymptomatic, treatment-naive women. Levels of HIV-1 RNA in cervicovaginal-lavage samples were positively correlated with those in plasma samples (r=.50; P=.008), whereas levels of HIV-1 DNA in genital samples were loosely correlated with those in blood samples (r=.31; P=.041). In plasma of peripheral blood, levels of HIV-1 DNA were positively correlated with those of HIV-1 RNA (r=.64; P<.001), whereas no correlation between HIV-1 DNA and HIV-1 RNA was evident in genital secretions. Our results indicate that levels of HIV-1 RNA and HIV-1 DNA are unrelated in the genital tracts of treatment-naive women and suggest that the level of genital HIV-1 RNA is influenced by systemic viral replication-in contrast to genital HIV-1 provirus, which may be influenced as well by local cofactors triggering the migration of HIV-infected cells originating from the cervicovaginal submucosa. These features may be relevant for an understanding of HIV-1 transmission in heterosexual individuals.

Pluripotent cells referred to as embryonic germ cells (EGCs) can be derived from the embryonic precursors of the mature gametes: the primordial germ cells (PGCs). A homozygous mutation (ter) of the dead-end homolog 1 gene (Dnd1) in the rat causes gonadal teratocarcinogenesis and sterility due to neoplastic transformation and loss of germ cells. We mated heterozygous ter/+ WKY-Dnd1(ter)/Ztm rats and were able to cultivate the first genital ridge-derived EGCs of the rat embryo at day 14.5 post coitum (pc). Genotyping revealed that ten EGC lines were Dnd1 deficient, while only one wild type cell line had survived in culture. This suggests that the inactivation of the putative tumor suppressor gene Dnd1 facilitates the immortalization of late EGCs in vitro. Injection of the wild type EGCs into blastocysts resulted in the first germ-line competent chimeras. These new pluripotent rat EGCs offer an innovative approach for studies on germ cell tumor development as well as a new tool for genetic manipulations in rats.

Five cases of amebiasis of the genital tract involving the cervix, vulva and penis are described. All presented as an ulcerating mass and were clinically suspected to have a tumor. In two cases the amebiasis co-existed with a carcinoma, an association which is extremely rare. The spouse of a patient with penile amebiasis was found to have amebiasis of the cervix suggesting a sexually transmitted mode of infection. The need for histopathological confirmation of all suspected genital malignancies is emphasised due to the striking resemblance of genital amebiasis to a carcinoma. The co-existence of amebiasis with carcinoma is of interest and suggests a possible etiological relationship.

Basaloid squamous cell carcinoma is a biologically aggressive neoplasm mainly found in the head and neck region. Recently, four cases of basaloid squamous cell carcinoma of the bladder have been reported, and three of them occurred in patients with neurogenic bladder, repeated catheterizations and human papillomavirus infection of the urinary tract. To the best of our knowledge, none of the patients affected by basaloid squamous cell carcinoma of the bladder described in the literature had documented genital involvement by human papillomavirus. Herein, we describe the case of a woman with neurogenic bladder affected by basaloid squamous cell carcinoma of the bladder and by a concomitant genital tract human papillomavirus infection. © 2014 The Japanese Urological Association.

Human genital infection caused by Chlamydia trachomatis is thought to be immunologically mediated, resulting in local recruitment of lymphocyte subsets and inducing the production of cytokines. Little information is available about the role of lymphocyte recruitment and the regulation of cytokine production in the genital tract of C. trachomatis positive infertile women. We have evaluated the recruitment of lymphocyte subsets in the genital tract and production of Th1/Th2 cytokines in cervical secretions and laparoscopic specimens from the fallopian tubes of C. trachomatis positive infertile women (n = 17) and compared them with controls, viz. C. trachomatis negative infertile women (n = 20) using ELISA and flow cytometry. None of these patients were found to be infected either with Candida sps., bacterial vaginosis, Trichomonas vaginalis, Neisseria gonorrhoeae, Mycoplasma hominis or Ureaplasma urealyticum in the cervix. Flow cytometric analysis of cervical secretions in Chlamydia positive women revealed recruitment of both CD4 and CD8 lymphocytes to the genital tract was up-regulated and a variation in the production rates of different cytokines in cervical secretions and fallopian tube was observed. We found that the immune responses in cervical secretions were of Th0 type, since all the analysed cytokines, viz. IFN-gamma, TNF-alpha, IL-10 and IL-12 were up-regulated. As, both CD4 and CD8 cells contribute to the production of IFN-gamma and IL-10, these results suggest that along with CD4 cells, CD8 lymphocytes also may be important for local regulation of Th1/Th2 responses in the genital tract during C. trachomatis infection.

Chronic inflammation of genital tract is thought to play a major role in male fertility disorder. Natural killer (NK) T cells are a heterogeneous group of T cells that share properties of both T cells and NK cells which display immunoregulatory properties. However, little is known regarding the presence and function of NK T cells in ejaculates from patients with chronic inflammation of genital tract. Invariant NK T (iNK T) cells were detected by invariant (Vα24-JαQ) TCR chain in ejaculates from patients suffering from chronic inflammation of genital tract (CIGT) using flow cytometry and immunofluorescence of double staining (n=40). Inflammatory cytokines interleukin (IL)-6, IL-17, and IFN-γ were detected in cell-free seminal plasma using an enzyme-linked immunosorbent assay (ELISA). The correlation between the percentage of iNK T cells and spermatozoa count, motility, vitality, seminal IL-6, IL-17, and IFN-γ was investigated. Significant percentages of iNK T cells above 10% were detected in 50% (CIGT-NKT(+) group). A negative correlation was detected between the percentage of iNK T cells and spermatozoa count (r=-.5957, P=.0056), motility (r=-.6163, P=.0038), and vitality (r=-.8032, P=.0019) in CIGT-NKT(+) group (n=20). Interestingly, a significant correlation of iNK T cells to seminal IL-6 (r=.7083, P=.0005), IFN-γ (r=.9578, P<.0001) was detected whereas lack of correlation between iNK T cells and IL-17 (r=-.1557, P=.5122) in CIGT-NKT(+) group. The proliferative response of iNK T cells could accompany an inflammatory response to spermatozoa and consequently influence sperm quality through secretion of IFN-γ but not IL-17 under chronic inflammatory condition.

The female genital mucosa constitutes the major port of entry of sexually transmitted infections. Most genital microbial pathogens represent an enormous challenge for developing vaccines that can induce genital immunity that will prevent their transmission. It is now established that long-lasting protective immunity at mucosal surfaces has to involve local B-cell and T-cell effectors as well as local memory cells. Mucosal immunization constitutes an attractive way to generate systemic and genital B-cell and T-cell immune responses that can control early infection by sexually transmitted pathogens. Nevertheless, no mucosal vaccines against sexually transmitted infections are approved for human use. The mucosa-associated immune system is highly compartmentalized and the selection of any particular route or combinations of routes of immunization is critical when defining vaccine strategies against genital infections. Furthermore, mucosal surfaces are complex immunocompetent tissues that comprise antigen-presenting cells and also innate immune effectors and non-immune cells that can act as 'natural adjuvants' or negative immune modulators. The functions of these cells have to be taken into account when designing tissue-specific antigen-delivery systems and adjuvants. Here, we will discuss data that compare different mucosal routes of immunization to generate B-cell and T-cell responses in the genital tract, with a special emphasis on the newly described sublingual route of immunization. We will also summarize data on the understanding of the effector and induction mechanisms of genital immunity that may influence the development of vaccine strategies against genital infections. © 2012 The Authors.

External genital warts, also known as condylomata acuminata, are extremely common, with between 500,000 to one million new cases diagnosed each year in the United States alone. To date, more than 120 distinct subtypes of human papillomavirus have been identified. Human papillomavirus types 6 and 11 rarely give rise to cervical cancers, but are responsible for 90 percent of the cases of genital warts. The current treatment options are largely centered upon removal of the warts rather than elimination of the underlying viral infection. A wide range of therapies are presently in use, which are highly variable and can differ dramatically with respect to cost, side-effect profiles, dosing schedules, duration of treatment, and overall effectiveness. As of yet, no definitive therapy has emerged as the ideal standard of care in the treatment of genital warts, and therapy selection generally occurs in a patient-specific manner. PMID:22768354

Genital herpes is a relatively common infection caused by herpes simplex virus (HSV) type one or two (HSV-1, HSV-2) respectively. It is acquired most commonly via sexual activity. More recently there has been an increase in infections due to HSV-1. Most new cases of genital HSV are not diagnosed due to HSV infections having short-lived signs and symptoms, or in many instances are asymptomatic. Hence many people infected with HSV are unaware that they have it. The risk of transmission to a partner is highest during outbreak periods, when there are visible lesions, although genital HSV can also be transmitted during asymptomatic periods. Use of condoms and antiviral medications assist in preventing transmission. Antiviral agents are effective in controlling clinical episodes, but do not eradicate infection, which remains latent for the life of a patient. Despite the surge in vaccine research, there is unfortunately no readily available preventative or therapeutic vaccine for HSV to date.

Primary female genital tract non Hodgkin's lymphoma is a rare presentation for a common disease in the childhood, and its classification as primary extranodal lymphoma is still controversial. There are a few cases reported as a primary precursor B-cell lymphoblastic lymphoma of the female genital tract, but there is not any case reported as primary precursor T-cell lymphoblastic lymphoma of the ovary in childhood. Herein we describe a 16 years old young woman with bilateral ovarian tumors, paraaortic lymphoadenophaty and disseminate disease to the female genital tract including extension of the tumor to neighboring organs like the omentum and the appendix. Exploratory laparatomy were performed with bilateral salpingo-oophorectomy, hysterectomy, omentectomy, appendectomy, pelvic and para-aortic lymphadenectomy, pelvic washings and with biopsy of vaginal vault. The chemotherapy regimen comprised of CHOP (Cyclophosphamide, Hydroxydaunorubicin, Oncovin, Prednisone/Prednisolone) and methotrexate, 3 months later presents left facial hemiparesia follow by right facial hemiparesia, 7 months later presents more Central Nervous System (CNS) complications and apparently was complicated with acute lymphocitic leukemia and after 16 months from the diagnosis, following by a torpid evolution, the pacient finally died.

Introduction External genital warts (EGWs) are sexually transmitted benign epidermal growths caused by the human papillomavirus (HPV), on the anogenital areas of both females and males. About 50% to 60% of sexually active women aged 18 to 49 years have been exposed to HPV infection, but only 10% to 15% will have genital warts. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments for external genital warts? What are the effects of interventions to prevent transmission of external genital warts? We searched: Medline, Embase, The Cochrane Library, and other important databases up to December 2009 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 55 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: bi- and trichloroacetic acid; condoms; cryotherapy; electrosurgery; imiquimod; intralesional, topical, or systemic interferons; laser surgery; podophyllin; podophyllotoxin; surgical excision; and vaccines.

Sexual transmission of human immunodeficiency virus (HIV) accounts for the majority of new infections worldwide. However, the mechanism of viral transmission across the mucosal barrier is poorly understood. By use of an ectocervical epithelium-derived cell line, we found that the cells are capable of sequestering large amounts of HIV particles but are refractory to cell-free viral infection. The sequestered virus particles remained infectious for >/=6 days and resisted treatment with trypsin. Upon coculture with CD4(+)-susceptible cells, epithelial cells can effectively transmit the virus to these cells, which can result in robust infection of the target cells. Inhibitory studies have shown that heparan sulfate moiety of cell-surface proteoglycans is involved in the viral attachment to these CD4-negative epithelial cells. Genital epithelial cells may play active roles in sequestering, protecting, and transferring virus during sexual transmission of HIV.

Genital human papillomavirus (HPV) infection is a common sexually transmitted disease that at the present time is not effectively controlled or treated. Many infections are inapparent and transient. However, some HPV infections result in persistent lesions that in some cases undergo carcinogenic progression. A subset of genital HPVs, designated high-risk types, are preferentially associated with high-grade dysplasias and carcinomas. About 90% of cervical cancers contain high-risk HPV DNA, most often HPV16. Development of a subunit vaccine against high-risk genital HPVs is a desirable and, it appears, an increasingly feasible long-term goal. The viral E6 and E7 oncoproteins are selectively maintained and expressed in progressed HPV tumors and could potentially be targets for therapeutic vaccines. The L1 major virion structural proteins have recently been shown to self-assemble into virus-like particles when expressed in insect cells. These particles might serve as the basis for a prophylactic vaccine to prevent genital HPV infection. Images PMID:8146136

The epithelium-stromal interaction is important in the process of morphogenesis, differentiation, and hormone response, in female genital tract. This review is organized in four sections: i) female genital tract morphogenesis, based on genetic determinism; ii) hormonal control of endometrial proliferation; iii) TGF-beta key-role in epithelium-stromal communication; iv) endometrial apoptosis. Female genital tract derives from the Müllerian ducts, a number of genes being involved in its regulation, like Lim1, Lhx9, Emx, Pax-2, Hox-A9, Hox-A10, Hox-A11, Hox-A13, Wnt-4, Wnt-7, WT1, SF-1, and GATA-4. TGF-beta, whose expression is modulated by ovarian steroids, regulates cell growth, differentiation, apoptosis, inflammatory and immune responses, extracellular matrix deposition, adhesion molecules, proteases, and protease inhibitor expression. In the endometrium, TGF-beta regulates its own expression, and that of extracellular matrix, adhesion molecules and proteases implicated in trophoblast invasion, angiogenesis, and tumor metastasis during embryo implantation, endometriosis, irregular bleeding, and endometrial cancer. Cellular response elicited by TGF-beta, mediated through a serine/threonine kinase receptor, induces the recruitment of multiple intracellular signals, specifically Smads, whose activation and subsequent translocation into the nucleus results in gene expression. Ubiquitin is involved in the degradation of short lived, regulatory or misfolded proteins, by tagging them to be taken to the proteasome. In the endometrium, ubiquitin may allow cells of stromal origin to grow, survive and evade T-cell mediated disposal, showing a functional duality. A complete understanding of the complex regulatory endometrial epithelium-stromal mechanism, concertating genes, hormones, and cytokines, may provide new therapeutic targets in female reproductive tract pathology.

Mucosal T lymphocyte responses in the female reproductive tract, the primary site of HIV transmission in women, may be critical for initial control of virus infection. In addition, characterization of genital immune responses to HIV will be important for the development of a vaccine capable of preventing infection by this route. We analyzed lymphocytes isolated from vagina and cervix of chronically SIV-infected macaques for the frequency of SIV Gag tetramer-binding cells and expression of chemokine receptors. We found that the frequency of SIV-specific CD8+ T cell responses was 3- to 30-fold higher in genital tissues than in peripheral blood. SIV-specific CD8+ T cells in genital tissues expressed high levels of CXCR3 and CCR5, chemokine receptors normally expressed on memory T cells that home to inflamed tissues. Cells expressing CXCR3 colocalized with its chemokine ligand CXCL9 [monokine induced by interferon gamma, MIG] in the vaginal lamina propria. These results indicate that the frequency of SIV-specific CD8+ T cells in the female genital mucosa is enriched compared with peripheral blood and provide initial information regarding the signals that direct recruitment of T cells to the female reproductive tract. © 2011 John Wiley & Sons A/S.

Local mucosal cellular immunity is critical in providing protection from HSV-2. To characterize and quantitate HSV-2-reactive mucosal T cells, lymphocytes were isolated from endocervical cytobrush and biopsy specimens from 17 HSV-2-infected women and examined ex vivo for the expression of markers associated with maturation and tissue residency and for functional T cell responses to HSV-2. Compared to their circulating counterparts, cervix-derived CD4+ and CD8+ T cells were predominantly effector memory T cells (CCR7−/CD45RA−) and the majority expressed CD69, a marker of tissue residency. Co-expression of CD103, another marker of tissue residency, was highest on cervix-derived CD8+ T cells. Functional HSV-2 reactive CD4+ and CD8+ T cells responses were detected in cervical samples and a median of 17% co-expressed CD103. HSV-2 reactive CD4+ T cells co-expressed IL-2 and were significantly enriched in the cervix compared to blood. This first direct ex vivo documentation of local enrichment of HSV-2 reactive T cells in the human female genital mucosa is consistent with the presence of antigen-specific tissue-resident memory T cells. Ex vivo analysis of these T cells may uncover tissue-specific mechanisms of local control of HSV-2 to assist the development of vaccine strategies that target protective T cells to sites of HSV-2 infection.

Antibodies that mediate human immunodeficiency virus (HIV)-specific antibody-dependent cell-mediated cytotoxicity (ADCC) are present in the cervical fluid of many HIV-positive women; however, the role that these antibodies play in host defense against HIV is not known. To understand the contribution of ADCC in cervical secretions as a protective mechanism against HIV, we evaluated ADCC titers in paired serum and cervical-lavage (CVL) samples from >300 HIV-1–positive women who participated in the multicenter Division of AIDS Treatment Research Initiative Study 009. The present study demonstrates that women with CVL ADCC activity had lower genital viral loads than did women with serum ADCC activity only. Women with CVL ADCC activity were likely to have HIV-1 gp120–specific immunoglobulin (Ig) G, but not IgA, in their cervical fluid. This finding suggests that specific IgG in cervical fluid can mediate ADCC activity that inversely correlates with genital viral load. PMID:15529262

Genital candidiasis occurs mainly in women referred as vulvovaginal candidiasis (VVC), and occasionally occurs in men as to be called balanitis. VVC is one of the most common causes of infectious vaginitis. Approximately three-quarters of women will experience an episode of VVC at least once in their life and 5-8% of them will have more than four attacks within a year; this condition has been designated as recurrent VVC (RVVC). Causative agent in majority of VVC is Candida albicans, but occasionally VVC is caused by other Candida spp. VVC is not traditionally considered a sexually transmitted disease. On occasion sexual transmission of Candida can occur during vaginal intercourse. Particularly Candida transmission and sexual behaviors are linked to RVVC. Epidemiological evidence suggests that anogenital and, especially, orogenital contact transmits Candida.

Oropharyngeal mucosal epithelia of fetuses/neonates/infants and the genital epithelia of adults play a critical role in HIV-1 mother-to-child transmission and sexual transmission of virus, respectively. To study the mechanisms of HIV-1 transmission through mucosal epithelium, we established polarized tonsil, cervical and foreskin epithelial cells. Analysis of HIV-1 transmission through epithelial cells showed that approximately 0.05% of initially inoculated virions transmigrated via epithelium. More than 90% of internalized virions were sequestered in the endosomes of epithelial cells, including multivesicular bodies (MVBs) and vacuoles. Intraepithelial HIV-1 remained infectious for 9 days without viral release. Release of sequestered intraepithelial HIV-1 was induced by the calcium ionophore ionomycin and by cytochalasin D, which increase intracellular calcium and disrupt the cortical actin of epithelial cells, respectively. Cocultivation of epithelial cells containing HIV-1 with activated peripheral blood mononuclear cells and CD4+ T lymphocytes led to the disruption of epithelial cortical actin and spread of virus from epithelial cells to lymphocytes. Treatment of epithelial cells with proinflammatory cytokines tumor necrosis factor-alpha and interferon gamma also induced reorganization of cortical actin and release of virus. Inhibition of MVB formation by small interfering RNA (siRNA)-mediated silencing of its critical protein hepatocyte growth factor-regulated tyrosine kinase substrate (Hrs) expression reduced viral sequestration in epithelial cells and its transmission from epithelial cells to lymphocytes by ~60–70%. Furthermore, inhibition of vacuole formation of epithelial cells by siRNA-inactivated rabankyrin-5 expression also significantly reduced HIV-1 sequestration in epithelial cells and spread of virus from epithelial cells to lymphocytes.

Chlamydia trachomatis urogenital serovars are intracellular bacteria that parasitize human reproductive tract epithelium. As the principal cell type supporting bacterial replication, epithelial cells are central to Chlamydia immunobiology initially as sentries and innate defenders, and subsequently as collaborators in adaptive immunity-mediated bacterial clearance. In asymptomatic individuals who do not seek medical care a decisive struggle between C. trachomatis and host defenses occurs at the epithelial interface. For this study, we modeled the immunobiology of epithelial cells and macrophages lining healthy genital mucosa and inflamed/infected mucosa during the transition from innate to adaptive immunity. Upper reproductive tract epithelial cell line responses were compared to bone marrow-derived macrophages utilizing gene expression microarray technology. Those comparisons showed minor differences in the intrinsic innate defenses of macrophages and epithelial cells. Major lineage-specific differences in immunobiology relate to epithelial collaboration with adaptive immunity including an epithelial requirement for inflammatory cytokines to express MHC class II molecules, and a paucity and imbalance between costimulatory and coinhibitory ligands on epithelial cells that potentially limits sterilizing immunity (replication termination) to Chlamydia-specific T cells activated with limited or unconventional second signals.

The global AIDS pandemic continues to expand and in some regions of the world, such as southern Africa, the prevalence of HIV-1 infection exceeds 20%. The devastating spread of the virus in young women in these countries appears disproportional to overall risk of infection. Regions with high prevalence of HIV-1 are often also highly endemic for other pathogenic viruses including HSV, CMV and HTLV. We propose that acquisition by HIV-1 of the envelope glycoproteins of other viruses, in a process we call “natural pseudotyping,” expands the cellular tropism of HIV-1, enabling it to infect female genital epithelial cells directly and thereby dramatically increasing risk of infection during sexual intercourse. In this proof-of-concept study, we demonstrate that when HIV-1 co-infects T cells along with the gammaretrovirus xenotropic murine leukemia virus-related virus (XMRV), progeny HIV-1 particles are produced capable of infecting primary vaginal, ectocervical and endocervical epithelial cells. These cell types are normally resistant to HIV-1 infection. Infection of primary genital cells was neutralized by antisera against the XMRV glycoprotein, confirming that infection was mediated by the XMRV glycoprotein acquired through pseudotyping of HIV. Inhibition by AZT showed that active replication of HIV-1 occurred in these cells and ruled out non-specific endocytic uptake of the virus. These results demonstrate that natural pseudotyping can expand the tropism of HIV-1 to include genital epithelial cells and have potential implications for sexual transmission of the virus.

Purpose Imiquimod is a toll-like receptor 7 agonist utilized topically to manage genital warts and basal cell carcinoma. We examine the combination of topical imiquimod with intramuscular administration of CRT/E7, a therapeutic HPV vaccination that comprises a naked DNA vector expressing calreticulin fused to HPV16 E7. Experimental Design Using an orthotopic HPV16 E6/E7+ syngeneic tumor, TC-1, as a model of high-grade cervical/vaginal/vulvar intraepithelial neoplasia, we show that combining CRT/E7 vaccination with cervicovaginal deposition of imiquimod results in synergistic immune-mediated tumor clearance. Results Imiquimod induces cervicovaginal accumulation of activated E7-specific CD8+ T cells elicited by CRT/E7 vaccination. Recruitment was not dependent upon the specificity of the activated CD8+ T cells, but was significantly reduced in mice lacking the IFNγ receptor. Intravaginal imiquimod deposition induced upregulation of CXCL9 and CXCL10 mRNA expression in the genital tract. These chemokines are expressed upon IFNγ receptor activation and attract cells expressing their receptor, CXCR3. In this study, T cells attracted by imiquimod to the cervicovaginal tract expressed CXCR3 as well as the tissue resident memory T cell (Trm) marker CD49a, a mucosal homing integrin. Our results indicate that intramuscular CRT/E7 vaccination in conjunction with intravaginal imiquimod deposition recruits antigen-specific CXCR3+CD8+ T cells to the genital tract. Conclusions Our study has potential clinical relevance because imiquimod is FDA approved for condyloma accuminata and basal cell carcinoma and intramuscular vaccination with pNGVL4a-CRT/E7(detox) is currently undergoing clinical testing, suggesting potential for their synergistic action to induce strong antigen-specific Trm-mediated immune responses and antitumor effects in genital mucosa.

Resolution of Chlamydia genital tract infection is delayed in the absence of MyD88. In these studies, we first used bone marrow chimeras to demonstrate a requirement for MyD88 expression by hematopoietic cells in the presence of a wild-type epithelium. Using mixed bone marrow chimeras we then determined that MyD88 expression was specifically required in the adaptive immune compartment. Furthermore, adoptive transfer experiments revealed that CD4+ T cell expression of MyD88 was necessary for normal resolution of genital tract infection. This requirement was associated with a reduced ability of MyD88−/− CD4+ T cells to accumulate in the draining lymph nodes and genital tract when exposed to the same inflammatory milieu as wild-type CD4+ T cells. We also demonstrated that the impaired infection control we observed in the absence of MyD88 could not be recapitulated by deficiencies in TLR or IL-1R signaling. In vitro, we detected an increased frequency of apoptotic MyD88−/− CD4+ T cells upon activation in the absence of exogenous ligands for receptors upstream of MyD88. These data reveal an intrinsic requirement for MyD88 in CD4+ T cells during Chlamydia infection and indicate that the importance of MyD88 extends beyond innate immune responses by directly influencing adaptive immunity.

Antimicrobial peptides (AMPs) are highly associated with antipathogenic activity, without generating drug resistance in targeted bacteria. In this study, the existence of AMPs in the Tibetan swine, a China-native, cold-resistant and seldom-sick breed of pig, was investigated. A peptide secreted by a Tibetan swine intestinal tract-derived Bacillus strain was isolated using reversed-phase chromatography (RPC), ultrafiltration and reversed-phase high-performance liquid chromatography (RP-HPLC). The peptide was identified by mass spectrometry and was characterised for activity against Escherichia coli and Staphylococcus aureus. The 16-amino acid peptide (ASVVNKLTGGVAGLLK), named TP, had a molecular mass of 1568.919 Da and exhibited inhibitory activity against Gram-positive and Gram-negative bacteria [minimum inhibitory concentrations (MICs) of 2.5-5 µM and 10-20 µM for E. coli and S. aureus, respectively] as well as human MKN-45 and NB4 tumour cell lines [50% inhibitory concentration (IC50) = 4.686 µM and 11.479 µM, respectively]. TP also exhibited weak haemolytic activity. Furthermore, TP enhanced cell membrane permeability and K(+) outflow, bound with E. coli genomic DNA in vitro and inhibited E. coli growth. Thus, TP represents a strong candidate as an antibacterial peptide.

Background Primary squamous cell carcinoma (SCC) of the upper genital tract, including the endometrium, fallopian tubes, and ovaries, is extremely rare. It must be distinguished from the mucosal extension of primary cervical SCC because determination of the primary tumor site is important for tumor staging. However, patients with SCC of the fallopian tubes or ovarian surface have often undergone prior hysterectomy with inadequate examination of the cervix, making it difficult to determine the primary site. Methods We compared histologic findings, p16INK4a expression, and human papillomavirus (HPV) DNA status in four patients with primary SCC of the upper genital tract and five patients with primary cervical SCC extending to the mucosa of the upper genital tract. Results All five SCCs of cervical origin showed strong expression of p16INK4a, whereas all four SCCs of the upper genital tract were negative, although one showed weak focal staining. Three of the five cervical SCCs were positive for HPV16 DNA, whereas all four primary SCCs of the upper genital tract were negative for HPV DNA. Conclusions Although a thorough histological examination is important, immunonegativity for p16INK4a and negative for HPV DNA may be useful adjuncts in determining primary SCCs of the upper genital tract.

The next generation of needle-free mucosal vaccines is being rationally designed according to rules that govern the way in which the epitopes are recognized by and stimulate the genital mucosal immune system. We hypothesized that synthetic peptide epitopes extended with an agonist of Toll-like receptor 2 (TLR-2), that are abundantly expressed by dendritic and epithelial cells of the vaginal mucosa, would lead to induction of protective immunity against genital herpes. To test this hypothesis, we intravaginally (IVAG) immunized wild-type B6, TLR-2 (TLR2 −/−) or myeloid differentiation factor 88 deficient (MyD88 −/−) mice with a herpes simplex virus type 2 (HSV-2) CD8 + T-cell peptide epitope extended by a palmitic acid moiety (a TLR-2 agonist). IVAG delivery of the lipopeptide generated HSV-2-specific memory CD8 + cytotoxic T cells both locally in the genital tract draining lymph nodes and systemically in the spleen. Moreover, lipopeptide-immunized TLR2 −/− and MyD88 −/− mice developed significantly less HSV-specific CD8 + T-cell response, earlier death, faster disease progression, and higher vaginal HSV-2 titers compared to lipopeptide-immunized wild-type B6 mice. IVAG immunization with self-adjuvanting lipid-tailed peptides appears to be a novel mucosal vaccine approach, which has attractive practical and immunological features. PMID:19129756

Murine genital infection induced with the mouse pneumonitis biovar of Chlamydia trachomatis (MoPn) elicits a short-lived protective immunity mediated primarily by Th1 CD4 cells. To understand the development of local cell-mediated immunity against C. trachomatis infection, we investigated the mechanism(s) which mediates CD4 lymphocyte migration to the genital mucosa by identifying molecules that could support this process. We found that primarily CD4 cells were recruited to the genital tract (GT) during primary and challenge MoPn infection. Peak levels were found 21 days after primary inoculation (15.4% +/- 2.7%) and 7 days (31.3% +/- 8.5%) after challenge but diminished after resolution of infection. The CD4 cells appeared to be recruited to the GT in response to infection since these cells expressed the profile of activated, or memory, cells. We also observed up-regulation of homing receptors containing LFA-1 (CD11a) and alpha4 (CD49d) on GT CD4 cells over the course of infection. Furthermore, the mucosal homing receptor chain, beta7, but not the peripheral homing receptor chain beta1 (CD29), was detected on GT CD4 cells. MoPn-infected GT tissue expressed the endothelial cell ligands vascular cell adhesion molecule 1 (VCAM-1), intracellular adhesion molecule 1 (ICAM-1), and mucosal vascular addressin cell adhesion molecule 1 (MAdCAM-1), which correspond to the homing receptors on GT CD4 cells. Interestingly, VCAM-1 and MAdCAM-1 were not expressed in the GTs of uninfected mice but were temporarily induced following infection, indicating that expression of endothelial ligands in the GT are regulated by chlamydial infection. These data suggest that recruitment of CD4 cells to the GT is mediated through LFA-1:ICAM-1 and alpha4beta7:MAdCAM-1-VCAM-1 interactions. PMID:9393816

Cervicovaginal lavage fluid (CVL) is a natural source of anti-HIV-1 factors; however, molecular characterization of the anti-HIV-1 activity of CVL remains elusive. In this study, we confirmed that CVLs from HIV-1-resistant (HIV-R) compared to HIV-1-susceptible (HIV-S) commercial sex workers (CSWs) contain significantly larger amounts of serine antiprotease trappin-2 (Tr) and its processed form, elafin (E). We assessed anti-HIV-1 activity of CVLs of CSWs and recombinant E and Tr on genital epithelial cells (ECs) that possess (TZM-bl) or lack (HEC-1A) canonical HIV-1 receptors. Our results showed that immunodepletion of 30% of Tr/E from CVL accounted for up to 60% of total anti-HIV-1 activity of CVL. Knockdown of endogenous Tr/E in HEC-1A cells resulted in significantly increased shedding of infectious R5 and X4 HIV-1. Pretreatment of R5, but not X4 HIV-1, with either Tr or E led to inhibition of HIV-1 infection of TZM-bl cells. Interestingly, when either HIV-1 or cells lacking canonical HIV-1 receptors were pretreated with Tr or E, HIV-1 attachment and transcytosis were significantly reduced, and decreased attachment was not associated with altered expression of syndecan-1 or CXCR4. Determination of 50% inhibitory concentrations (IC(50)) of Tr and E anti-HIV-1 activity indicated that E is ∼130 times more potent than its precursor, Tr, despite their equipotent antiprotease activities. This study provides the first experimental evidence that (i) Tr and E are among the principal anti-HIV-1 molecules of CVL; (ii) Tr and E affect cell attachment and transcytosis of HIV-1; (iii) E is more efficient than Tr regarding anti-HIV-1 activity; and (iv) the anti-HIV-1 effect of Tr and E is contextual.

The female genital tract (FGT) mucosa is a critically important site for immune defense against microbes. Mucosal-associated invariant T (MAIT) cells are an innate-like T cell population that recognizes microbial riboflavin metabolite antigens in an MR1-dependent manner. The role of MAIT cells in the FGT mucosa is unknown. Here, we found that MAIT cells and MR1+ antigen-presenting cells were present in the upper and lower FGT, with distinct tissue localization of MAIT cells in endometrium versus cervix. MAIT cells from the FGT and blood displayed a distinct phenotype with expression of IL-18Rα, CD127, α4β7, PD-1, as well as the transcription factors PLZF, RORγt, Helios, Eomes and T-bet. Their expression levels of PLZF and Eomes were lower in the FGT compared to blood. When stimulated with Escherichia coli, MAIT cells from the FGT displayed a bias towards IL-17 and IL-22 expression, whereas blood MAIT cells produced primarily IFN-γ, TNF, and Granzyme B. Furthermore, both FGT- and blood-derived MAIT cells were polyfunctional and contributed to the T cell-mediated response to E. coli. Thus, MAIT cells in the genital mucosa have a distinct IL-17/IL-22 profile and may play an important role in immunological homeostasis and control of microbes at this site. PMID:27049062

Dendritic cells (DC) are often arranged in planar layers in tissues with high antigenic exposure, such as skin and mucosae. Providing an en face view, this arrangement optimizes in situ analysis regarding morphology (even of individual dendrites), topographic distribution (regular/clustered) and quantification. The few reports on human genital DC usually utilize single markers and conventional sections, restricting immunolabelling only to cell parts sectioned by the cut. To better assess DC in situ, we labelled epithelial sheets, prepared from fresh cervix biopsies, with antibodies to major histocompatibility complex (MHC)-CII, CD1a and Langerin, revealing (with each of these markers) a dense DC network in a planar-like, regular distribution. Using the hybrid capture system to detect the high-risk mucotropic human papilloma virus (HPV) group, 16 positive and five negative women were studied and the results were compared between these groups. DC frequency per area was substantially reduced (to ≈ 50% for the three markers) in samples from all HPV-infected patients compared with samples from controls. Unlike HPV– samples, Langerin+ DC in HPV+ cervix exhibited a highly accentuated dendritic appearance. We believe this to be the first study using these three DC-restricted markers (Langerin, CD1a and MHC-CII) in cervical epithelial sheets from high-risk HPV+ donors and also the first study to demonstrate the morphological and quantitative changes triggered by high-risk HPV infection. Cervical DC reduction in early, premalignant high-risk HPV infection might represent viral subversion strategies interfering with efficient antigen handling by the immune system's peripheral sentinels, the DC, perhaps hampering appropriate recruitment and subsequent development of effector (cytotoxic) T cells.

Male genital lichen sclerosus (MGLSc) is a chronic inflammatory skin disease responsible for male sexual dyspareunia and urological morbidity. An afeared complication is squamous cell carcinoma (SCC) of the penis. The precise etiopathogenesis of MGLSc remains controversial although genetic, autoimmune and infective (such as human papillomavirus (HPV) hepatitis C (HCV), Epstein-Barr virus (EBV) and Borrelia) factors have been implicated: Consideration of all the evidence suggests that chronic exposure of susceptible epithelium to urinary occlusion by the foreskin seems the most likely pathomechanism. The mainstay of treatment is topical ultrapotent corticosteroid therapy. Surgery is indicated for cases unresponsive to topical corticosteroid therapy, phimosis, meatal stenosis, urethral stricture, carcinoma in situ (CIS) and squamous cell carcinoma. PMID:25814697

Leukocytes participate in the immune control of herpes simplex virus (HSV). Data from HIV coinfections, germ line mutations, and case reports suggest involvement of CD4 T cells and plasmacytoid dendritic cells (pDC). We investigated the relationships between these cells and recurrent genital herpes disease severity in the general population. Circulating CD4 T-cell responses to HSV-2 were measured in specimens from 67 immunocompetent individuals with measured genital lesion and HSV shedding rates. Similarly, pDC number and functional responses to HSV-2 were analyzed in 40 persons. CD4 responses and pDC concentrations and responses ranged as much as 100-fold between persons while displaying moderate within-person consistency over time. No correlations were observed between these immune response parameters and genital HSV-2 severity. Cytomegalovirus (CMV) coinfection was not correlated with differences in HSV-2-specific CD4 T-cell responses. The CD4 T-cell response to HSV-2 was much more polyfunctional than was the response to CMV. These data suggest that other immune cell subsets with alternate phenotypes or anatomical locations may be responsible for genital herpes control in chronically infected individuals.

Vaginal infection with the mouse pneumonitis agent of Chlamydia trachomatis (MoPn) produces shorter courses of infection in C57BL/6 and BALB/c mice than in C3H/HeN mice, while C57BL/6 mice are more resistant to oviduct pathology. A robust Th1 response is extremely important in host defense against chlamydia. In this study we examined gamma interferon (IFN-gamma), interleukin 10 (IL-10), and the T-cell-regulatory chemokines macrophage inflammatory protein-1alpha (MIP-1alpha) and monocyte chemoattractant protein-1 (MCP-1) to determine if differences in these responses were associated with the differential courses of infection seen in these three strains of mice. Increased and prolonged IFN-gamma responses and lower IL-10 responses were observed in the C57BL/6 strain compared to BALB/c and C3H. Examination of genital tract chemokines revealed a marked predominance of MIP-1alpha over MCP-1 only in the C57 strain. Thus, a pattern of high MIP-1alpha and low MCP-1 levels during the first week of infection is associated with an increased Th1 response and a shorter, more benign chlamydial infection. Inhibition of the MCP-1 response in C3H mice increased their later T-cell production of IFN-gamma but decreased their early IFN-gamma response and had no effect on the course or outcome of infection. Inhibition of MCP-1 is not beneficial in chlamydial infection because of its pleiotropic effects.

Chlamydia trachomatis infection is considered the most prevalent bacterial sexually transmitted disease worldwide. C.trachomatis causes eye infections such as trachoma and newborn inclusion conjunctivitis, newborn pneumonia, genitourinary system infections and suppurative inguinal lymphadenitis namely lymphogranuloma venerum. The aim of this study was to investigate C.trachomatis by direct fluorescent antibody (DFA), polymerase chain reaction (PCR) and cell culture methods in the clinical samples sent to the microbiology laboratory with the prediagnosis of genital infections. A total of 50 swab samples obtained from adult patients (49 female, 1 male) who were admitted to Erciyes University Hospital, Kayseri, Turkey between February-March 2010, were included in the study. C.trachomatis antigens were investigated by a commercial DFA (PathoDx, Remel, USA) method. McCoy cell cultures prepared in microplate wells were used for the isolation of C.trachomatis. The growth of C.trachomatis in cell cultures was confirmed by DFA and iodine staining methods. C.trachomatis DNA was investigated by commercially available PCR (Chlamydia trachomatis 330/740 IC; Sacace, Italy) method. In our study, 4 (8%) of the 50 swab samples were found positive with DFA, 1 (2%) was positive with cell culture, and 1 (2%) was positive with PCR. The only sample that gave positive results with all of the three methods was an urethral swab. Three cervical swab samples that were found positive only with DFA method was evaluated as false positivity. When cell culture was considered as the reference method, the sensitivity and specificity of DFA method were estimated as 100% and 94%, respectively, while those rates for PCR were 100% and 100%, respectively. In conclusion, although cell culture is still the gold standard in the diagnosis of C.trachomatis. infections, since it is time consuming and difficult to apply, more rapid and reliable PCR methods may be applied in diagnosis.

The potential role of T cells in the control of human papillomavirus type 6 (HPV-6) infections is an appealing premise, but their actual role has been sparsely investigated. Since HPV-6 infections are confined to the epithelium, such an investigation should focus on the T cells present at the site of infection (i.e., the warts). Therefore, we isolated wart-infiltrating lymphocytes (WIL) from patients with clinically diagnosed anogenital warts. These WIL were characterized by their phenotype and their specificity for E7 and L1 proteins of HPV-6. The phenotype of WIL varied drastically from patient to patient, as determined by their expression of CD4, CD8, T-cell receptor alpha/beta chain (TCR alpha beta), and TCR gamma delta. Despite this heterogeneity in phenotype, HPV-6 E7 and/or L1-specific WIL, as determined by lymphoproliferation, could be isolated from more than 75% of the patients studied. Among all L1 peptides recognized by WIL, peptides 311-330 and 411-430 were the most consistently detected, with seven of nine patients for whom L1 peptide reactivity was observed responding to at least one of them. Moreover, the HPV-6 epitopic peptides recognized by WIL differed to some extent from those recognized by peripheral T cells. PMID:9261360

We and others have shown that HIV-1 highly-exposed seronegative (HESN) female commercial sex workers (CSWs) maintain low genital inflammatory conditions to prevent HIV infection. HIV-1 interacts with toll-like receptors (TLR)-7/8 to induce interferon (IFN)-α, an important antiviral and immunomodulatory cytokine, which act together with interleukin (IL)-10, human leukocyte antigen (HLA)-G and immunoglobulin-like transcript (ILT)-4 to initiate a “tolerogenic/regulatory” anti-inflammatory loop. In view of further unravelling elements associated with natural immunity to HIV-1, we have characterised TLR-7, IFN-α, IL-10, HLA-G and ILT-4 expression profiles in the genital tract of female CSWs and HIV-1-uninfected non-CSWs from Benin. Endocervical myeloid HLA-DR+ cells from HESN CSWs expressed higher levels of IFN-α, TLR-7, IL-10 and HLA-G than those from both HIV-1-infected CSWs and HIV-1-uninfected non-CSWs. Further characterization of the endocervical myeloid HLA-DR+ cells in HESN CSWs revealed a population of “tolerogenic” CD103+ CD14+ CD11c+ myeloid cells expressing high levels of IFN-α and IL-10. Concomitantly, HESN CSWs had higher frequencies of endocervical regulatory CD4+ T-cells when compared to those from the two other groups of women. These novel findings provide strong evidence to support the implication of tolerogenic myeloid cells expressing high levels of antiviral molecules in shaping the genital mucosal immune response to prevent HIV infection.

Human papillomavirus type 16 (HPV16) early proteins E6 and E7 have been implicated in maintenance of the malignant phenotype in cervical cancer. Transforming growth factors beta one and two (TGF betas 1 and 2), polypeptides that regulate cellular growth and differentiation, reversibly inhibited expression of the HPV16 E6 and E7 genes in several immortal genital epithelial cell lines. Loss of E6 and E7 protein expression followed a dramatic time- and dose-dependent decrease in E6 and E7 RNA levels and was accompanied by cessation of cell proliferation. TGF betas 1 and 2 inhibited HPV16 RNA expression at the transcriptional level; inhibition was dependent upon ongoing protein synthesis. TGF betas 1 and 2 also induced a six- to sevenfold increase in TGF beta 1 RNA. Cells became partially resistant to the inhibitory effects of TGF beta 1 on cell growth and HPV early gene expression after prolonged cultivation in vitro or after malignant transformation. Thus, TGF beta 1 may function as an autocrine regulator of HPV gene expression in infected genital epithelial cells. Images PMID:2168964

Herpes simplex virus (HSV) entry requires multiple interactions at the cell surface and activation of a complex calcium signaling cascade. Previous studies demonstrated that integrins participate in this process, but their precise role has not been determined. These studies were designed to test the hypothesis that integrin αvβ3 signaling promotes the release of intracellular calcium (Ca2+) stores and contributes to viral entry and cell-to-cell spread. Transfection of cells with small interfering RNA (siRNA) targeting integrin αvβ3, but not other integrin subunits, or treatment with cilengitide, an Arg-Gly-Asp (RGD) mimetic, impaired HSV-induced Ca2+ release, viral entry, plaque formation, and cell-to-cell spread of HSV-1 and HSV-2 in human cervical and primary genital tract epithelial cells. Coimmunoprecipitation studies and proximity ligation assays indicated that integrin αvβ3 interacts with glycoprotein H (gH). An HSV-2 gH-null virus was engineered to further assess the role of gH in the virus-induced signaling cascade. The gH-2-null virus bound to cells and activated Akt to induce a small Ca2+ response at the plasma membrane, but it failed to trigger the release of cytoplasmic Ca2+ stores and was impaired for entry and cell-to-cell spread. Silencing of integrin αvβ3 and deletion of gH prevented phosphorylation of focal adhesion kinase (FAK) and the transport of viral capsids to the nuclear pore. Together, these findings demonstrate that integrin signaling is activated downstream of virus-induced Akt signaling and facilitates viral entry through interactions with gH by activating the release of intracellular Ca2+ and FAK phosphorylation. These findings suggest a new target for HSV treatment and suppression. Herpes simplex viruses are the leading cause of genital disease worldwide, the most common infection associated with neonatal encephalitis, and a major cofactor for HIV acquisition and transmission.

Although clinical and experimental evidence indicates that female sex hormones and hormonal contraceptives regulate susceptibility to human immunodeficiency virus type 1 (HIV-1) infection, the underlying mechanism remains unknown. Genital epithelial cells (GECs) are the first cells to encounter HIV during sexual transmission and their interaction with HIV may determine the outcome of exposure. This is the first report that HIV uptake by GECs increased significantly in the presence of the hormonal contraceptive medroxyprogesterone acetate (MPA) and progesterone and that uptake occurred primarily via endocytosis. No productive infection was detected, but endocytosed virus was released into apical and basolateral compartments. Significantly higher viral transcytosis was observed in the presence of MPA. In GEC and T-cell cocultures, maximum viral replication in T cells was observed in the presence of MPA, which also broadly upregulated chemokine production by GECs. These results suggest that MPA may play a significant role in regulating susceptibility to HIV. © The Author 2014.

Targeting of the mucosal immune system of the genital tract with subunit vaccines has failed to induce potent and durable local CD8(+) T cell immunity, which is crucial for protection against many sexually transmitted viral pathogens, including HSV type 2 (HSV-2), which causes genital herpes. In this study, we aimed to investigate the potential of a novel lipopeptide/adenovirus type 5 (Lipo/rAdv5) prime/boost mucosal vaccine for induction of CD8(+) T cell immunity to protect the female genital tract from herpes. The lipopeptide vaccine and the rAdv5 vaccine express the immunodominant HSV-2 CD8(+) T cell epitope (gB(498-505)), and both were delivered intravaginally in the progesterone-induced B6 mouse model of genital herpes. Compared with mice immunized with the homologous lipopeptide/lipopeptide (Lipo/Lipo) vaccine, the Lipo/rAdv5 prime/boost immunized mice 1) developed potent and sustained HSV-specific CD8(+) T cells, detected in both the genital tract draining nodes and in the vaginal mucosa; 2) had significantly lower virus titers; 3) had decreased overt signs of genital herpes disease; and 4) did not succumb to lethal infection (p < 0.005) after intravaginal HSV-2 challenge. Polyfunctional CD8(+) T cells, producing IFN-γ, TNF-α, and IL-2 and exhibiting cytotoxic activity, were associated with protection (p < 0.005). The protective CD8(+) T cell response was significantly compromised in the absence of the adapter MyD88 (p = 0.0001). Taken together, these findings indicate that targeting of the vaginal mucosa with a Lipo/rAdv5 prime/boost vaccine elicits a potent, MyD88-dependent, and long-lasting mucosal CD8(+) T cell protective immunity against sexually transmitted herpes infection and disease.

Although mastermind-like domain containing 1 (MAMLD1) (CXORF6) on human chromosome Xq28 has been shown to be a causative gene for 46,XY disorders of sex development with hypospadias, the biological function of MAMLD1/Mamld1 remains to be elucidated. In this study, we first showed gradual and steady increase of testicular Mamld1 mRNA expression levels in wild-type male mice from 12.5 to 18.5 d postcoitum. We then generated Mamld1 knockout (KO) male mice and revealed mildly but significantly reduced testicular mRNA levels (65–80%) of genes exclusively expressed in Leydig cells (Star, Cyp11a1, Cyp17a1, Hsd3b1, and Insl3) as well as grossly normal testicular mRNA levels of genes expressed in other cell types or in Leydig and other cell types. However, no demonstrable abnormality was identified for cytochrome P450 17A1 and 3β-hydroxysteroid dehydrogenase (HSD3B) protein expression levels, appearance of external and internal genitalia, anogenital distance, testis weight, Leydig cell number, intratesticular testosterone and other steroid metabolite concentrations, histological findings, in situ hybridization findings for sonic hedgehog (the key molecule for genital tubercle development), and immunohistochemical findings for anti-Müllerian hormone (Sertoli cell marker), HSD3B (Leydig cell marker), and DEAD (Asp-Glu-Ala-Asp) box polypeptide 4 (germ cell marker) in the KO male mice. Fertility was also normal. These findings imply that Mamld1 deficiency significantly reduces mRNA expression levels of multiple genes expressed in mouse fetal Leydig cells but permits normal genital and reproductive development. The contrastive phenotypic findings between Mamld1 KO male mice and MAMLD1 mutation positive patients would primarily be ascribed to species difference in the fetal sex development. PMID:23087174

Evidence from clinical and epidemiological studies indicates that women are disproportionately susceptible to sexually transmitted viral infections. To understand the underlying biological basis for this increased susceptibility, more studies are needed to examine the acute events in the female reproductive tract following exposure to viruses during sexual transmission. The epithelial lining of the female reproductive tract is the primary barrier that sexually transmitted viruses, such as HIV-1 and HSV-2 need to infect or traverse, in order to initiate and establish productive infection. We have established an ex-vivo primary culture system to grow genital epithelial cells from upper reproductive tract tissues of women. Using these cultures, we have extensively examined the interactions between epithelial cells of the female genital tract and HSV-2 and HIV-1. In this review, we describe in detail the experimental protocol to grow these cultures, monitor their differentiation and inoculate with HSV-2 and HIV-1. Prospective use of these cultures to re-create the microenvironment in the reproductive tract is discussed.

Genital herpes is a sexually transmitted disease caused by the herpes simplex virus. Following the initial infection the virus becomes latent in the sacral ganglia. Approximately 80% of patients are then subject to milder but unpredictable recurrences and may shed the virus even when they are asymptomatic. The disorder causes concern because genital herpes in the mother can result in rare but catastrophic neonatal infection and because of a possible association between genital herpes and cancer of the cervix. No effective treatment is as yet available. Weekly monitoring for virus by cervical culture from 32 weeks' gestation is recommended for women with a history of genital herpes and for those whose sexual partner has such a history.

Background Racial residential segregation is hypothesized to affect population health by systematically patterning health-relevant exposures and opportunities according to individuals' race or income. Growing interest into the association between residential segregation and health disparities demands more rigorous appraisal of commonly used measures of segregation. Most current studies rely on census tracts as approximations of the local residential environment when calculating segregation indices of either neighborhoods or metropolitan areas. Because census tracts are arbitrary in size and shape, reliance on this geographic scale limits understanding of place-health associations. More flexible, explicitly spatial derivations of traditional segregation indices have been proposed but have not been compared with tract-derived measures in the context of health disparities studies common to social epidemiology, health demography, or medical geography. We compared segregation measured with tract-derived as well as GIS surface-density-derived indices. Measures were compared by region and population size, and segregation measures were linked to birth record to estimate the difference in association between segregation and very preterm birth. Separate analyses focus on metropolitan segregation and on neighborhood segregation. Results Across 231 metropolitan areas, tract-derived and surface-density-derived segregation measures are highly correlated. However overall correlation obscures important differences by region and metropolitan size. In general the discrepancy between measure types is greatest for small metropolitan areas, declining with increasing population size. Discrepancies in measures are greatest in the South, and smallest in Western metropolitan areas. Choice of segregation index changed the magnitude of the measured association between segregation and very preterm birth. For example among black women, the risk ratio for very preterm birth in metropolitan

The epidemiology of genital herpes is changing. The seroprevalence of HSV-2 infections is increasing, while HSV-1 is an increasingly common cause of herpetic ulcerations. The reference examination provides direct diagnosis after viral isolation in a cell culture or genome amplification. Herpes serology is indicated principally if direct examination is negative and in the absence of lesions. Non-type-specific serology detects antibodies common to HSV-1 and HSV-2. Its specificity and sensitivity are excellent, and it is approved as a reimbursable laboratory procedure. It cannot specify the viral type involved. Type-specific serology can distinguish between anti-HSV-1 and anti-HSV-2 antibodies. Currently available kits have a sensitivity and specificity, depending on the population studied, of 90 to 100%. It is not approved as a reimbursable laboratory procedure. HSV-1-specific serology cannot diagnose old HSV-1 genital infections, but seropositivity for HSV-2 generally suffices to diagnose HSV-2 genital herpes. The indication for type-specific serology must be discussed according to clinical context. The value of non-type-specific serology is limited.
Clinical, subclinical, and latent human papillomavirus (HPV) infections are distinguished from HPV-associated neoplasia. Besides HPV additional cofactors are necessary to transform HPV infected tissue to intraepithelial or invasive neoplasia. Risk factors for the presence of HPV are high number of sexual partners, early cohabitarche, young age at first delivery, suppression and alteration of immune status, young age and hormonal influences. While the fact of a high number of sexual partners exclusively increases the risk of HPV infection, it is not known whether the other factors lead to either an increased risk for HPV infection and/or to HPV-associated neoplasia. Subclinical and latent genital HPV infections are highly prevalent. The prevalence rate depends on the sensitivity of the HPV detection system used, on age and sexual activity of the population screened, and on the number of subsequent examinations performed for each subject. Sexual transmission is the main pathway for genital HPV's, however, vertical, peripartal, and oral transmission are also possible. Seroreactivity against genital HPV may be due to an active infection or the result of contact with HPV earlier in life. Antibodies against the HPV 16 E7 protein indicate an increased risk for cervical cancer. Compared with humoral response cellular immune response is probably more important for regression of genital HPV infection: impaired cellular response is characterized by depletion of T helper/inducer cells and/or Langerhans cells and impaired function of natural killer cells and/or the infected keratinocyte. In condylomata replication and transcription of viral nucleic acids and antigen production coincide with cellular differentiation. However, the interaction between HPV and the keratinocyte on a molecular level in subclinical and latent disease is not well understood. Regression or persistence of subclinical and latent genital HPV infections as observed in longitudinal investigations show a

Giant cell arteritis (GCA) is an immunologically mediated vasculitis of large and medium-sized vessels, typically affecting the cranial arteries and usually occurring in the elderly. GCA of the female genital tract is extremely rare with only 31 cases reported in the English literature. An 83-year-old white female with postmenopausal vaginal bleeding revealed an endometrial polyp on pelvic ultrasonography following which polypectomy and subsequently hysterectomy with bilateral salpingo-oophorectomy was done. Microscopy revealed a well-differentiated endometrioid adenocarcinoma. Interestingly, classic GCA involving numerous small to medium-sized arteries of the cervix, myometrium, bilateral fallopian tubes, and ovaries was also identified. Hematologic evaluation revealed marginal zone lymphoma with an exceptionally rare 20q deletion. Bilateral temporal artery biopsy was done subsequently, which exhibited GCA on microscopy. Corticosteroid was started that improved her polymyalgia rheumatica symptoms. The patient is on follow-up for 3 years and is doing well. To our knowledge, this is the first case of GCA of the female genital tract associated with a lymphoma and the second case of marginal zone lymphoma with the novel 20q deletion. © The Author(s) 2015.

Background Tissue resident memory T cells (TrM) provide an enhanced response against infection at mucosal surfaces, yet their function has not been extensively studied in humans, including the female genital tract (FGT). Methods Using polychromatic flow cytometry, we studied TrM cells, defined as CD62L−CCR7−CD103+CD69+ CD4+ and CD8+ T cells in mucosa-derived T cells from healthy and HIV-positive women. Results We demonstrate that TrM are present in the FGT of healthy and HIV-positive women. The expression of the mucosal retention receptor, CD103, from HIV-positive women was reduced compared to healthy women and was lowest in women with CD4 counts < 500 cells/mm3. Furthermore, CD103 expression on mucosa-derived CD8+ T cells correlated with antigen-specific IFN-γ production by mucosal CD4+ T cells and was inversely correlated with T-bet from CD8+CD103+ mucosa-derived T cells. Conclusions These data suggest that CD4+ T cells, known to be impaired during HIV-1 infection and necessary for the expression of CD103 in murine models, may play a role in the expression of CD103 on resident T cells from the human FGT.

Targeting the mucosal immune system of the genital tract (GT) with subunit vaccines failed to induce potent and durable local CD8+ T cell immunity, crucial for protection against many sexually transmitted viral (STV) pathogens, including herpes simplex virus type 2 (HSV-2) that causes genital herpes. In this study, we aimed to investigate the potential of a novel lipopeptide/adenovirus type 5 (Lipo/rAdv5) prime/boost mucosal vaccine for induction of CD8+ T cell immunity to protect the female genital tract from herpes. The lipopeptide and the rAdv5 vaccine express the immunodominant HSV-2 CD8+ T cell epitope (gB498-505) and both were delivered intravaginally (IVAG) in the progesterone-induced B6 mouse model of genital herpes. Compared to its homologous lipopeptide/lipopeptide (Lipo/Lipo); the Lipo/rAdv5 prime/boost immunized mice: (i) developed potent and sustained HSV-specific CD8+ T cells, detected in both the GT draining nodes (GT-DLN) and in the vaginal mucosa (VM); (ii) had significantly lower virus titers; (iii) had decreased overt signs of genital herpes disease; and (iv) did not succumb to lethal infection (p < 0.005), following intravaginal HSV-2 challenge. Polyfunctional CD8+ T cells, producing IFN-γ, TNF-α and IL-2 and exhibiting cytotoxic activity, were associated with protection (p < 0.005). The protective CD8+ T cell response was significantly compromised in the absence of the adaptor myeloid differentiation factor 88 (MyD88) (p = 0.0001). Taken together, these findings indicate that targeting the VM with a Lipo/rAdv5 prime/boost vaccine elicits a potent, MyD88-dependent, and long-lasting mucosal CD8+ T cell protective immunity against sexually transmitted herpes infection and disease.

An efficacious vaccine is needed to control Chlamydia trachomatis infection. In the murine model of Chlamydia muridarum genital infection, multifunctional mucosal CD4 T cells are the foundation for protective immunity, with antibody playing a secondary role. We previously identified four Chlamydia outer membrane proteins (PmpE, PmpF, PmpG and PmpH) as CD4 T cell vaccine candidates using a dendritic cell-based immunoproteomic approach. We also demonstrated that these four polymorphic membrane proteins (Pmps) individually conferred protection as measured by accelerated clearance of Chlamydia infection in the C57BL/6 murine genital tract model. The major outer membrane protein, MOMP is also a well-studied protective vaccine antigen in this system. In the current study, we tested immunogenicity and protection of a multisubunit recombinant protein vaccine consisting of the four Pmps (PmpEFGH) with or without the major outer membrane protein (MOMP) formulated with a Th1 polarizing adjuvant in C57BL/6, Balb/c and C3H mice. We found that C57BL/6 mice vaccinated with PmpEFGH+MOMP elicited more robust cellular immune responses than mice immunized with individual protein antigens. Pmps elicited more variable cellular immune responses than MOMP among the three strains of mice. The combination vaccine accelerated clearance in the three strains of mice although at different rates. We conclude that the recombinant outer membrane protein combination constitutes a promising first generation Chlamydia vaccine construct that should provide broad immunogenicity in an outbred population.

Etiology, transmission and protection: Chlamydia trachomatis is the leading cause of bacterial sexually transmitted infection (STI) globally. However, C. trachomatis also causes trachoma in endemic areas, mostly Africa and the Middle East, and is a leading cause of preventable blindness worldwide. Epidemiology, incidence and prevalence: The World Health Organization estimates 131 million new cases of C. trachomatis genital infection occur annually. Globally, infection is most prevalent in young women and men (14-25 years), likely driven by asymptomatic infection, inadequate partner treatment and delayed development of protective immunity. Pathology/Symptomatology: C. trachomatis infects susceptible squamocolumnar or transitional epithelial cells, leading to cervicitis in women and urethritis in men. Symptoms are often mild or absent but ascending infection in some women may lead to Pelvic Inflammatory Disease (PID), resulting in reproductive sequelae such as ectopic pregnancy, infertility and chronic pelvic pain. Complications of infection in men include epididymitis and reactive arthritis. Molecular mechanisms of infection: Chlamydiae manipulate an array of host processes to support their obligate intracellular developmental cycle. This leads to activation of signaling pathways resulting in disproportionate influx of innate cells and the release of tissue damaging proteins and pro-inflammatory cytokines. Treatment and curability: Uncomplicated urogenital infection is treated with azithromycin (1 g, single dose) or doxycycline (100 mg twice daily x 7 days). However, antimicrobial treatment does not ameliorate established disease. Drug resistance is rare but treatment failures have been described. Development of an effective vaccine that protects against upper tract disease or that limits transmission remains an important goal. PMID:28357377
The examination of the rape victim should focus on the therapeutic, forensic and psychological needs of the individual patient. One aspect will be an examination for ano-genital injuries. From a medical perspective, they tend to be minor and require little in the way of treatment. They must be considered when assessing the risk of blood-borne viruses and the need for prophylaxis. From a forensic perspective, an understanding of genital injury rates, type of injury, site and healing may assist the clinician to interpret the findings in the context of the allegations that have been made. There are many myths and misunderstandings about ano-genital injuries and rape. The clinician has a duty to dispel these.

Androgen is an essential factor involved in masculinization of external genitalia. Failure of the exposure to 5α-dihydrotestosterone (DHT) causes a hypoplastic penile size and urethral abnormality. The main pathology of hypospadias is defective urethral closure on the ventral side of the penis. Hormone-dependent genes are suggested as the causative factors. However, the detailed mechanisms of DHT functions on urethral tube formation remain unknown. Androgen is both a positive and negative regulator of cell proliferation. The roles of locally converted DHT in cell proliferation at the periurethral mesenchyme have not been elucidated. We revealed the expression pattern of 5α-reductase type 2 mRNA (Srd5a2) and local DHT distribution by direct measurement in this study. We also analyzed periurethral mesenchymal cell proliferation status using systematic three-dimensional (3D) reconstruction analyses. A prominent Srd5a2 expression and localized DHT distribution on the ventral side of the genital tubercle were detected. Cell proliferation was reduced in this mesenchymal region during urethral formation. The current results suggest the presence of the possible negative regulation of cell proliferation by DHT. Moreover, cell proliferation related to urethral tube formation was revealed to be DHT dose dependent. These data are expected to contribute to the understanding of the mode of regulation of cell proliferation related to urethral tube formation by DHT. These findings may also offer insight into the understanding of human hypospadias and related hormone-dependent factors.

The female genital tract (FGT) provides a means of entry to pathogens, including HIV, yet immune cell populations at this barrier between host and environment are not well defined. We initiated a study of healthy women to characterize resident T cell populations in the lower FGT from lavage and patient-matched peripheral blood to investigate potential mechanisms of HIV sexual transmission. Surprisingly, we observed FGT CD4 T cell populations were primarily CCR7(hi), consistent with a central memory or recirculating memory T cell phenotype. In addition, roughly half of these CCR7(hi) CD4 T cells expressed CD69, consistent with resident memory T cells, whereas the remaining CCR7(hi) CD4 T cells lacked CD69 expression, consistent with recirculating memory CD4 T cells that traffic between peripheral tissues and lymphoid sites. HIV susceptibility markers CCR5 and CD38 were increased on FGT CCR7(hi) CD4 T cells compared with blood, yet migration to the lymphoid homing chemokines CCL19 and CCL21 was maintained. Infection with GFP-HIV showed that FGT CCR7(hi) memory CD4 T cells are susceptible HIV targets, and productive infection of CCR7(hi) memory T cells did not alter chemotaxis to CCL19 and CCL21. Variations of resident CCR7(hi) FGT CD4 T cell populations were detected during the luteal phase of the menstrual cycle, and longitudinal analysis showed the frequency of this population positively correlated to progesterone levels. These data provide evidence women may acquire HIV through local infection of migratory CCR7(hi) CD4 T cells, and progesterone levels predict opportunities for HIV to access these novel target cells.

Genital infections with herpes simplex virus type 2 (HSV-2) are a source of considerable morbidity and are a health concern for newborns exposed to virus during vaginal delivery. Additionally, HSV-2 infection diminishes the integrity of the vaginal epithelium resulting in increased susceptibility of individuals to infection with other sexually transmitted pathogens. Understanding immune protection against HSV-2 primary infection and immune modulation of virus shedding events following reactivation of the virus from latency is important for the development of effective prophylactic and therapeutic vaccines. Although the murine model of HSV-2 infection is useful for understanding immunity following immunization, it is limited by the lack of spontaneous reactivation of HSV-2 from latency. Genital infection of guinea pigs with HSV-2 accurately models the disease of humans including the spontaneous reactivation of HSV-2 from latency and provides a unique opportunity to examine virus-host interactions during latency. Although the guinea pig represents an accurate model of many human infections, relatively few reagents are available to study the immunological response to infection. To analyze the cell-mediated immune response of guinea pigs at extended periods of time after establishment of HSV-2 latency, we have modified flow-cytometry based proliferation assays and IFN-γ ELISPOT assays to detect and quantify HSV-specific cell-mediated responses during latent infection of guinea pigs. Here we demonstrate that a combination of proliferation and ELISPOT assays can be used to quantify and characterize effecter function of virus-specific immune memory responses during HSV-latency.
MyD88 deficiency leads to decreased NK cell gamma interferon production and T cell recruitment during Chlamydia muridarum genital tract infection, but a predominant Th1 response and enhanced monocytic inflammation are associated with infection resolution.

We have previously shown that MyD88 knockout (KO) mice exhibit delayed clearance of Chlamydia muridarum genital infection compared to wild-type (WT) mice. A blunted Th1 response and ineffective suppression of the Th2 response were also observed in MyD88 KO mice. The goal of the present study was to investigate specific mechanisms whereby absence of MyD88 leads to these effects and address the compensatory mechanisms in the genital tract that ultimately clear infection in the absence of MyD88. It was observed that NK cells recruited to the genital tract in MyD88 KO mice failed to produce gamma interferon (IFN-γ) mRNA and protein. This defect was associated with decreased local production of interleukin-17 (IL-17), IL-18, and tumor necrosis factor alpha (TNF-α) but normal levels of IL-12p70. Additionally, recruitment of CD4 T cells to the genital tract was reduced in MyD88 KO mice compared to that in WT mice. Although chronic infection in MyD88 KO mice resulted in oviduct pathology comparable to that of WT mice, increased histiocytic inflammation was observed in the uterine horns. This was associated with increased CCL2 levels and recruitment of macrophages as a potential compensatory mechanism. Further deletion of TLR4-TRIF signaling in MyD88 KO mice, using TLR4/MyD88 double-KO mice, did not further compromise host defense against chlamydiae, suggesting that compensatory mechanisms are Toll-like receptor (TLR) independent. Despite some polarization toward a Th2 response, a Th1 response remained predominant in the absence of MyD88, and it provided equivalent protection against a secondary infection as observed in WT mice.

Development of safe and effective Chlamydia trachomatis vaccines requires better understanding of the host immune responses elicited by natural infection. Peripheral blood mononuclear cells isolated from women with or without history of genital tract chlamydial infection were stimulated with inactivated C. trachomatis elementary bodies (EB) in ELISPOT assays that enumerated frequencies of cells producing interferon (IFN)-γ or interleukin (IL)-17. IFN-γ-positive cells were highest among women sampled 30-60 days after diagnosis of C. trachomatis infection and treatment initiation, while the numbers of IFN-γ-positive cells were equally low among uninfected women and women sampled <30 or >60 days after diagnosis of infection. Conversely, IL-17-positive cell numbers were uniformly low among all participants. Dramatically reduced numbers of Chlamydia-specific Th1 memory cells in the peripheral circulation of study participants sampled more than 2 months after diagnosis, and initiation of treatment provides new insight into the results from C. trachomatis vaccine trials, in which immunization with EB provided only short-lived protection. Our results also suggest that an effective vaccine against this weakly antigenic intracellular pathogen will need to generate immunological memory more durable than that elicited by natural infection. © 2012 John Wiley & Sons A/S.

Understanding the immune profile of CD4 T cells, the primary targets for HIV, in the female genital tract (FGT) is critical for evaluating and developing effective biomedical HIV prevention strategies in women. However, longitudinal investigation of HIV susceptibility markers expressed by FGT CD4 T cells has been hindered by low cellular yield and risk of sampling-associated trauma. We investigated three minimally invasive FGT sampling methods to characterize and compare CD4 T cell yield and phenotype with the goal of establishing feasible sampling strategies for immune profiling of mucosal CD4 T cells. FGT samples were collected bimonthly from 12 healthy HIV negative women of reproductive age in the following order: 1) Cervicovaginal lavage (CVL), 2) two sequential endocervical flocked swabs (FS), and 3) two sequential endocervical cytobrushes (CB1, CB2). Cells were isolated and phentoyped via flow cytometry. CD4 T cell recovery was highest from each individual CB compared to either CVL or FS (p < 0.0001). The majority of CD4 T cells within the FGT, regardless of sampling method, expressed CCR5 relative to peripheral blood (p < 0.01). Within the CB, CCR5+ CD4 T cells expressed significantly higher levels of α4β7, CD69, and low levels of CD27 relative to CCR5- CD4 T cells (all p < 0.001). We also identified CD4 Treg lineage cells expressing CCR5 among CB samples. Using three different mucosal sampling methods collected longitudinally we demonstrate that CD4 T cells within the FGT express CCR5 and α4β7 and are highly activated, attributes which could act in concert to facilitate HIV acquisition. FS and CB sampling methods can allow for investigation of strategies to reduce HIV target cells in the FGT and could inform the design and interpretation microbicide and vaccine studies in women.

Female genital mutilation, also misleadingly known as female circumcision, is usually performed on girls ranging in from 1 week to puberty. Immediate physical complications include severe pain, shock, infection, bleeding, acute urinary infection, tetanus, and death. Longterm problems include chronic pain, difficulties with micturition and menstruation, pelvic infection leading to infertility, and prolonged and obstructed labor during childbirth. An estimated 80 million girls and women have undergone female genital mutilation. In Britain alone an estimated 10,000 girls are currently at risk. Religious, cultural, medical, and moral grounds rationalize the custom which is practiced primarily in sub-Saharan Africa, the Arab world, Malaysia, Indonesia, and among migrant populations in Western countries. According to WHO it is correlated with poverty, illiteracy, and the low status of women. Women who escape mutilation are not sought in marriage. WHO, the UN Population Fund, the UN Children's Fund, the International Planned Parenthood Federation, and the UN Convention on the Rights of the Child have issued declarations on the eradication of female genital mutilation. In Britain, local authorities have intervened to prevent parents from mutilating their daughters. In 1984, the Inter-African Committee Against Harmful Traditional Practices Affecting Women and Children was established to work toward eliminating female genital mutilation and other damaging customs. National committees in 26 African countries coordinate projects run by local people using theater, dance, music, and storytelling for communication. In Australia, Canada, Europe, and the US women have organized to prevent the practice among vulnerable migrants and refugees.
Hypospadias is a developmental defect of urethral tube closure that has a complex etiology. Here, we describe a multicellular agent-based model of genital tubercle development that simulates urethrogenesis from the urethral plate stage to urethral tube closure in differentiating male embryos. The model, constructed in CompuCell3D, implemented spatially dynamic signals from SHH, FGF10, and androgen signaling pathways. These signals modulated stochastic cell behaviors, such as differential adhesion, cell motility, proliferation, and apoptosis. Urethral tube closure was an emergent property of the model that was quantitatively dependent on SHH and FGF10 induced effects on mesenchymal proliferation and endodermal apoptosis, ultimately linked to androgen signaling. In the absence of androgenization, simulated genital tubercle development defaulted to the female condition. Intermediate phenotypes associated with partial androgen deficiency resulted in incomplete closure. Using this computer model, complex relationships between urethral tube closure defects and disruption of underlying signaling pathways could be probed theoretically in multiplex disturbance scenarios and modeled into probabilistic predictions for individual risk for hypospadias and potentially other developmental defects of the male genital tubercle. We identify the minimal molecular network that determines the outcome of male genital tubercle development in mice.

To detect the effect of Nocardia rubra cell wall skeleton (Nr-CWS) on tumorigenicity induced by TC-1 cells and to clinically study anti-human papillomavirus effect of Nr-CWS in lower genital tract of women. Tumor model was established by injecting TC-1 cells subcutaneously in SCID mice, then divided them into 3 groups randomly and injected with isovolumetric physiological saline, 60 micrograms/ml Nr-CWS and 120 micrograms/ml Nr-CWS respectively, the growth of tumors was measured one week later. Nr-CWS was applied on 45 HPV positive women whose TCT test was normal and without cervical erosion 2-3 days after menstruation. HPV was detected again 3 months later to explore the effect of Nr-CWS on HPV infection in female lower genital tract. The animal experiment showed the weight of transplanted tumors in treated group was less than that of control group (chi2=12.5, P= 0.002). The tumor inhibition rate was 59.1 percent and 84.2 percent in the groups treated with Nr-CWS 60 and 120 micrograms/ml Nr-CWS; the results of HPV detection in 23 out of the 45 cases (51.1 percent) became negative after the 3-month treatment; the viral load was reduced in 9, and there was no change in viral load in 13 cases. Significant difference was found between the rates of undetectable viral load and the natural viral disappearance rate (P less than 0.05). Nr-CWS has an inhibitory effect to TC-1 cell tumorigenesis and clinical application of Nr-CWS may eliminate the HPV infection in lower genital tract of a considerable proportion of women with HPV infection.

Ano-genital warts are considered one of the commonest and highly infectious sexually transmitted infections. These warts are primarily caused by the human papillomavirus (HPV) of the family Papillomaviridae, genus alpha-papillomavirus, species 10 and types 6 and 11. However the high recurrence rate of warts is a matter of serious concern to the patients and a challenge for the treating physician. The conventional treatment options are targeted only to the local site of warts. There is no systemic treatment modality as there is limited understanding of the disease immune-pathogenesis. The role of cell-mediated immunity in combating HPV infection is not clearly defined. Hence the present study is aimed at investigating the CD4(+) T helper (Th1 and Th2) and CD8(+) T cell responses among wart patients. In this study, we compared HPV6 and HPV11 antigen-specific T cell responses among venereal wart patients relative to healthy controls. Significant decrease in percent frequencies of IFN-γ producing CD4(+) and CD8(+) T cells were observed in HPV infected wart patients. On the other hand, the frequency of CD4(+) T cells expressing IL-4 was significantly increased in these patients as compared to healthy controls. The observed functional skewing of HPV specific T cells from Th1 to Th2 response in patients indicated suppressed immunity against the HPV. Moreover, decrease in CD8 T cell function correlated with poor wart clearance. Our findings open future avenues for exploring potential immunomodulation strategies as an adjunct to standard treatment for better management of these patients and prevention of recurrence.

Persistent genital arousal disorder (PGAD) is a phenomenon, in which afflicted women experience spontaneous genital arousal, unresolved by orgasms and triggered by sexual or nonsexual stimuli, eliciting stress. The current case is a 40-year-old female who experienced such orgasms for about a month. Physical examination, investigations, and psychological testing were noncontributory. Carbamazepine (600 mg) was discontinued due to a lack of response. She improved significantly with supportive therapy. Various neuropsychological conditions, pelvic pathology, medications, etc., have been associated with this disorder. Pharmacologic strategies have included the use of antidepressants, antipsychotics, mood stabilizers, and analgesics. Validation, psycho-education, identifying triggers, distraction techniques, and pelvic massage have been tried. Living with PGAD is very demanding. There is a lack of understanding of the problem, shame, and hesitation to seek help. The syndrome has been recently described, and understanding is still evolving. PMID:27570347

Introduction Genital chlamydia is the most commonly reported bacterial sexually transmitted infection (STI) in developed countries. In women, infection occurs most commonly between the ages of 16 and 19 years. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of antibiotic treatment for men and non-pregnant women with uncomplicated genital chlamydial infection?What are the effects of antibiotic treatment for pregnant women with uncomplicated genital chlamydial infection? We searched: Medline, Embase, The Cochrane Library, and other important databases up to September 2009 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 24 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: amoxicillin, ampicillin, azithromycin, ciprofloxacin, clarithromycin, clindamycin, doxycycline, erythromycin, lymecycline, minocycline, ofloxacin, pivampicillin, rifampicin, roxithromycin, sparfloxacin, tetracycline, and trovafloxacin.

The discrepancy in societal attitudes toward female genital cosmetic surgery for European women and female genital cutting in primarily African girl children and women raises the following fundamental question. How can it be that extensive genital modifications, including reduction of labial and clitoral tissue, are considered acceptable and perfectly legal in many European countries, while those same societies have legislation making female genital cutting illegal, and the World Health Organization bans even the "pricking" of the female genitals? At present, tensions are obvious as regards the modification of female genitalia, and current legislation and medical practice show inconsistencies in relation to women of different ethnic backgrounds. As regards the right to health, it is questionable both whether genital cosmetic surgery is always free of complications and whether female genital cutting always leads to them. Activists, national policymakers and other stakeholders, including cosmetic genital surgeons, need to be aware of these inconsistencies and find ways to resolve them and adopt non-discriminatory policies. This is not necessarily an issue of either permitting or banning all forms of genital cutting, but about identifying a consistent and coherent stance in which key social values - including protection of children, bodily integrity, bodily autonomy, and equality before the law - are upheld.

Although modern Chlamydia muridarum has been passaged for decades, there are no reports on the consequences of serial passage with strong selection pressure on its fitness. In order to explore the potential for Pasteurian selection to induce genomic and phenotypic perturbations to C. muridarum, a starter population was passaged in cultured cells for 28 generations without standard infection assistance. The resultant population, designated CMG28, displays markedly reduced in vitro dependence on centrifugation for infection and low incidence and severity of upper genital tract pathology following intravaginal inoculation into mice compared to the parental C. muridarum population, CMG0. Deep sequencing of CMG0 and CMG28 revealed novel protein variants in the hypothetical genes TC0237 (Q117E) and TC0668 (G322R). In vitro attachment assays of isogenic plaque clone pairs with mutations in either TC0237 and TC0668 or only TC0237 reveal that TC0237(Q117E) is solely responsible for enhanced adherence to host cells. Paradoxically, double mutants, but not TC0237(Q117E) single mutants, display severely attenuated in vivo pathogenicity. These findings implicate TC0237 and TC0668 as novel genetic factors involved in chlamydial attachment and pathogenicity, respectively, and show that serial passage under selection pressure remains an effective tool for studying Chlamydia pathogenicity.

A Dual-Modality Herpes Simplex Virus 2 Vaccine for Preventing Genital Herpes by Using Glycoprotein C and D Subunit Antigens To Induce Potent Antibody Responses and Adenovirus Vectors Containing Capsid and Tegument Proteins as T Cell Immunogens
Mahairas, Gregory G.; Shaw, Carolyn E.; Huang, Meei-Li; Koelle, David M.; Posavad, Christine; Corey, Lawrence; Friedman, Harvey M.
ABSTRACT We evaluated a genital herpes prophylactic vaccine containing herpes simplex virus 2 (HSV-2) glycoproteins C (gC2) and D (gD2) to stimulate humoral immunity and UL19 (capsid protein VP5) and UL47 (tegument protein VP13/14) as T cell immunogens. The HSV-2 gC2 and gD2 proteins were expressed in baculovirus, while the UL19 and UL47 genes were expressed from replication-defective adenovirus vectors. Adenovirus vectors containing UL19 and UL47 stimulated human and murine CD4+ and CD8+ T cell responses. Guinea pigs were either (i) mock immunized; (ii) immunized with gC2/gD2, with CpG and alum as adjuvants; (iii) immunized with the UL19/UL47 adenovirus vectors; or (iv) immunized with the combination of gC2/gD2-CpG/alum and the UL19/UL47 adenovirus vectors. Immunization with gC2/gD2 produced potent neutralizing antibodies, while UL19 and UL47 also stimulated antibody responses. After intravaginal HSV-2 challenge, the mock and UL19/UL47 adenovirus groups developed severe acute disease, while 2/8 animals in the gC2/gD2-only group and none in the combined group developed acute disease. No animals in the gC2/gD2 or combined group developed recurrent disease; however, 5/8 animals in each group had subclinical shedding of HSV-2 DNA, on 15/168 days for the gC2/gD2 group and 13/168 days for the combined group. Lumbosacral dorsal root ganglia were positive for HSV-2 DNA and latency-associated transcripts for 5/8 animals in the gC2/gD2 group and 2/8 animals in the combined group. None of the differences comparing the gC2/gD2-only group and the combined group were statistically significant. Therefore, adding the T cell immunogens UL19 and UL47 to the gC2/gD2 vaccine did not significantly reduce genital disease and vaginal HSV-2 DNA shedding compared with the excellent protection provided by gC2/gD2 in the guinea pig model. IMPORTANCE HSV-2 infection is a common cause of genital ulcer disease and a significant public health concern. Genital herpes increases the risk of

Extracardiac rhabdomyomas are rare benign entities that usually occur in the head and neck region. Although genital rhabdomyoma is known to occur in the lower genital tract of young and middle-aged women, involvement of the anatomically adjacent urethra by rhabdomyoma is exceedingly rare. We present a case of genital rhabdomyoma arising from the urethra of an infant girl. The tumor was characterized by the submucosal presence of mature-appearing rhabdomyoblastic cells containing conspicuous cross-striations, with the cells set in a collagenous stroma. Necrosis and mitoses were absent. Skeletal muscle differentiation of the tumor cells was supported by positive immunohistochemical staining for desmin and myogenin. To our knowledge, this is the first case of urethral genital-type rhabdomyoma in a child.

Genital prolapses are the result of musculo-ligamentary alterations often caused or complicated by traumatic delivery and senible atrophy of the tissues. From 1969 to 1988, we gathered 104 files of patients with genital prolapses. The age of the patients ranged from 20 to 70 years with an average age of 30. The subject between the ages of 20 and 39 were the most affected (64%). The average number of children per woman was 4. 60 patients had 5 children. No case of prolapses was found among virgin or mulliparous women. In 48 cases delivery was dystocic. The clinical symptomatology was a feeling of intravaginal globus, pelvic algia and discomfort (57 cases). Straingul urinary incontinence wax manifest in 15 patients. Colpocystocele (88 cases), rectocele (66 cases) and hysterocele (50 cases) were among the most frequently evidence lesions. On the therapeutic matter, the low passage was used 58 times and the high passage 32 times. An urinary gesture was made 33 times. There was no operatory fatality. Urinary troubles related to infection, acute retention of urine and strainful urinary incontinence were observed. Later 10 cases of recurrence were observed within an average time interval of 2 years. This work is characterized by the young age of the patients. It denotes the noticeable role played by obstétrical traumatisms in the genesis of genital prolapses in the African context. The senescence and atrophy of the tissues seem to have a less important role in contrast with the developed countries. Finally, the surgical treatment of these patients must take into account, among other things, the child bearing desire of the patients, given the social and psychological weight of maternity in our society.
Genital amebiasis is not a frequent entity. Its association with cancer is still more rare. The author found just two other cases reported in the literature reviewed since 1892 up to date. A clinico-pathologic study was made of 4 cases of this uncommon coexistence: in two patients the lesions were located in the vulva; in the other two at the cervix uteri. Two of them showed eczematous reactions that disappeared with the antiamebian treatment; they were considered as Amebids, though mechanisms of photosensitivity.

Porokeratosis of Mibelli is a disorder of epidermal proliferation in which many different clinical forms can be distinguished. Two male patients with a localized type of porokeratosis limited to the genitalia are reported. Later in life they developed an annular skin lesion with peripheral keratotic ridge. The histological examination of a biopsy specimen showed the characteristic features of porokeratosis. There was no family history of similar skin disorders and the patients were not on any drugs. Genital porokeratosis is probably underdiagnosed and we believe that these patients should be followed up on account of the precancerous potential of this disease. Images PMID:8566987

Genital herpes simplex virus infection is a recurrent, lifelong disease with no cure. The strongest predictor for infection is a person's number of lifetime sex partners. The natural history includes first-episode mucocutaneous infection, establishment of latency in the dorsal root ganglion, and subsequent reactivation. Most infections are transmitted via asymptomatic viral shedding. Classic outbreaks consist of a skin prodrome and possible constitutional symptoms such as headache, fever, and inguinal lymphadenopathy. As the infection progresses, papules, vesicles on an erythematous base, and erosions appear over hours to days. These lesions usually crust, re-epithelialize, and heal without scarring. First-episode infections are more extensive: primary lesions last two to six weeks versus approximately one week for lesions in recurrent disease. Atypical manifestations are common. Infected persons experience a median of four recurrences per year after their first episode, but rates vary greatly. Genital herpes simplex virus type 2 recurs six times more frequently than type 1. Viral culture is preferred over polymerase chain reaction testing for diagnosis. Serologic testing can be useful in persons with a questionable history. Effective oral antiviral medications are available for initial, episodic, and suppressive therapy but are not a cure. There is some evidence that alternative therapies such as L-lysine, zinc, and some herbal preparations may offer some benefit. Counseling patients about the risk of transmission is crucial and helps prevent the spread of disease and neonatal complications.

Genital herpes is a common sexually transmitted disease, affecting more than 400 million persons worldwide. It is caused by herpes simplex virus (HSV) and characterized by lifelong infection and periodic reactivation. A visible outbreak consists of single or clustered vesicles on the genitalia, perineum, buttocks, upper thighs, or perianal areas that ulcerate before resolving. Symptoms of primary infection may include malaise, fever, or localized adenopathy. Subsequent outbreaks, caused by reactivation of latent virus, are usually milder. Asymptomatic shedding of transmissible virus is common. Although HSV-1 and HSV-2 are indistinguishable visually, they exhibit differences in behavior that may affect management. Patients with HSV-2 have a higher risk of acquiring human immunodeficiency virus (HIV) infection. Polymerase chain reaction assay is the preferred method of confirming HSV infection in patients with active lesions. Treatment of primary and subsequent outbreaks with nucleoside analogues is well tolerated and reduces duration, severity, and frequency of recurrences. In patients with HSV who are HIV-negative, treatment reduces transmission of HSV to uninfected partners. During pregnancy, antiviral prophylaxis with acyclovir is recommended from 36 weeks of gestation until delivery in women with a history of genital herpes. Elective cesarean delivery should be performed in laboring patients with active lesions to reduce the risk of neonatal herpes.

In women, infection occurs most commonly between the ages of 16 and 19 years. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of antibiotic treatment in men, non-pregnant women, and pregnant women with uncomplicated genital chlamydia infection? We searched: Medline, Embase, The Cochrane Library, and other important databases up to January 2007 (BMJ Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 24 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review, we present information relating to the effectiveness and safety of the following interventions: amoxicillin, ampicillin, azithromycin, ciprofloxacin, clarithromycin, clindamycin, doxycycline, erythromycin, lymecycline, minocycline, ofloxacin, pivampicillin, rifampicin, roxithromycin, sparfloxacin, tetracycline, and trovafloxacin.

Lichen sclerosus is a chronic inflammatory mucocutaneous disease which origin remains unknown. Its prevalence ranges from one in 300 to one in 1000 of all patients referred to a dermatology clinic in the seventeenth. Through the analysis of a hospital survey, we outline the epidemio-clinical aspects of this dermatosis. Over a 19-year period (1984-2002), we have conducted a retrospective and monocentric study of all patients with genital lichen sclerosus were examined at the dermatology department of Habib Thameur hospital. Thirty-four patients suffered from lichen sclerosus. There were 33 female and only one male (sex-ratio: 0.03). All patients underwent topical corticosteroid therapy (level I, II or IV). The recovery rate of lichen sclerosus was about 20% (7/34). An epidermoid carcinoma occurred in three patients. The frequency of lichen sclerosus in our study is estimated at 1,8 new cases per year. This frequency is probably under-estimated because of some patients' reluctance to seek help. A relatively low recovery rate of genital lichen sclerosus was found in our study. This may be related to an inadequate follow up added to an insufficient treatment adherence.

Acute genital ulcers, also known as acute vulvar ulcers, ulcus vulvae acutum or Lipschütz ulcers, refer to an ulceration of the vulva or lower vagina of non-venereal origin that usually presents in young women, predominantly virgins. Although its incidence is unknown, it seems a rare entity, with few cases reported in the literature. Their aetiology and pathogenesis are still unknown. The disease is characterised by an acute onset of flu-like symptoms with single or multiple painful ulcers on the vulva. Diagnosis is mainly clinical, after exclusion of other causes of vulvar ulcers. The treatment is mainly symptomatic, with spontaneous resolution in 2 weeks and without recurrences in most cases. We present a case report of a 13-year-old girl with two episodes of acute ulcers that fit the clinical criteria for Lipschütz ulcers.

Summary Background The use of injectable progestin-only contraceptives has been associated with increased risk of HIV acquisition in observational studies, but the biological mechanisms of this risk remain poorly understood. We aimed to assess the effects of progestins on HIV acquisition risk and the immune environment in the female genital tract. Methods In this prospective cohort, we enrolled HIV-negative South African women aged 18–23 years who were not pregnant and were living in Umlazi, South Africa from the Females Rising through Education, Support, and Health (FRESH) study. We tested for HIV-1 twice per week to monitor incident infection. Every 3 months, we collected demographic and behavioural data in addition to blood and cervical samples. The study objective was to characterise host immune determinants of HIV acquisition risk, including those associated with injectable progestin-only contraceptive use. Hazard ratios (HRs) were estimated using Cox proportional hazards methods. Findings Between Nov 19, 2012, and May 31, 2015, we characterised 432 HIV-uninfected South African women from the FRESH study. In this cohort, 152 women used injectable progestin-only contraceptives, 43 used other forms of contraception, and 222 women used no method of long-term contraception. Women using injectable progestin-only contraceptives were at substantially higher risk of acquiring HIV (12·06 per 100 person-years, 95% CI 6·41–20·63) than women using no long-term contraception (3·71 per 100 person-years, 1·36–8·07; adjusted hazard ratio [aHR] 2·93, 95% CI 1·09–7·868, p=0·0326). HIV-negative injectable progestin-only contraceptive users had 3·92 times the frequency of cervical HIV target cells (CCR5+ CD4 T cells) compared with women using no long-term contraceptive (p=0·0241). Women using no long-term contraceptive in the luteal phase of the menstrual cycle also had a 3·25 times higher frequency of cervical target cells compared with those in the
Senegal has joined Burkina Faso, the Central African Republic, Djibouti, Ghana, and Togo in outlawing female genital mutilation and assigning penalties of up to five years imprisonment to those who order or perform the procedure. Currently, 20% of Senegalese women have undergone female genital mutilation, and many girls are thought to have died as a result. UN agencies have made their opposition to female genital mutilation clear and have argued that women attempting to avoid the procedure should be granted asylum in other countries.

Background We investigated the role of infection with genital and cutaneous human papillomavirus types (HPV) in the aetiology of ocular surface squamous neoplasia (which includes both conjunctival intraepithelial neoplasia (CIN) and carcinoma) using data and biological material collected as part of a case-control study in Uganda. Results Among 81 cases, the prevalence of genital and cutaneous HPV types in tumour tissue did not differ significantly by histological grade of the lesion. The prevalence of genital HPV types did not differ significantly between cases and controls (both 38%; Odds ratio [OR] 1.0, 95% confidence interval [CI] 0.4–2.7, p = 1.0). The prevalence of cutaneous HPV types was 22% (18/81) among cases and 3% (1/29) among controls (OR 8.0, 95% CI 1.0–169, p = 0.04). Conclusion We find no evidence of an association between genital HPV types and ocular surface squamous neoplasia. The prevalence of cutaneous HPV was significantly higher among cases as compared to controls. Although consistent with results from two other case-control studies, the relatively low prevalence of cutaneous HPV types among cases (which does not differ by histological grade of tumour) indicates that there remains considerable uncertainty about a role for cutaneous HPV in the aetiology of this tumour.

The spectrum of genital HPV infections comprises clinical, subclinical, and latent disease in addition to HPV-associated neoplasia. The definition of subclinical and latent HPV infection is still incomplete and awaits clarification by highly sensitive HPV detection systems that preserve the morphology of the tissue. Genital HPVs infect the human body mainly by sexual transmission, but other pathways of HPV transmission may be possible as suggested by (a) high prevalences of antibody reactivity in children; (b) lack of association of HPV seropositivity with sexual activity; (c) presence of HPV DNA in oral cavity scrapings of children and adults; and (d) development of recurrent respiratory papillomatosis among children exposed to HPV 6 or 11 during birth. Successful infection depends on the infection site and the immunological state of the host: susceptibility to genital HPVs seems highest for the squamous epithelium of the lower genital tract. HPV DNA is also present in extragenital sites but this is rarely accompanied by clinical or subclinical lesions. The molecular basis for this specific tropism is unknown. The immune response in HPV-infected tissues is characterized by depletion of T helper/inducer cells or Langerhans cells and an impaired immunological function of natural killer cells or the infected keratinocyte. Epidemiological studies indicate that individuals with cell-mediated immunodeficiencies are at increased risk for genital HPV infections. Data about the biological course of genital HPV infections are just beginning to emerge. Regression or persistence of subclinical and latent genital HPV infections as analysed in longitudinal investigations show a constant come-and-go of HPV presence. In an infected individual, complete clearing of the virus seems rather exceptional. With respect to progression, the biological potential of cervical HPV infections is characterized by an increased risk for development of HPV-associated neoplasia, especially in
Genital symptoms in tropical countries and among returned travellers can arise from a variety of bacterial, protozoal, and helminthic infections which are not usually sexually transmitted. The symptoms may mimic classic sexually transmitted infections (STIs) by producing ulceration (for example, amoebiasis, leishmaniasis), wart-like lesions (schistosomiasis), or lesions of the upper genital tract (epididymo-orchitis caused by tuberculosis, leprosy, and brucellosis; salpingitis as a result of tuberculosis, amoebiasis, and schistosomiasis). A variety of other genital symptoms less suggestive of STI are also seen in tropical countries. These include hydrocele (seen with filariasis), which can be no less stigmatising than STI, haemospermia (seen with schistosomiasis), and hypogonadism (which may occur in lepromatous leprosy). This article deals in turn with genital manifestations of filariasis, schistosomiasis, amoebiasis, leishmaniasis, tuberculosis and leprosy and gives clinical presentation, diagnosis, and treatment.

Recent studies indicate that tonsillar gonococcal infection or colonization is fairly common. Carriage rates of about 8% have been found. These studies also indicate that oro-genital contacts are common. Since very little is known about the amount of oral microbiota transmitted to the genitals, we have studied the occurrence of oral streptococci and Neisseria species in urethra and cervix. Among 128 patients attending an STD-clinic we found 10 carriers of oral streptococci, one Streptococcus mitior, four Streptococcus sanguis, one Streptococcus mutans and four Streptococcus salivarius and case of urethritis due to Neisseria menigitidis. Seventy-three of the patients had recently had their genitals exposed to the oral flora of their partners. Despite the heavy contamination with oral microbiota that can be assumed to occur in these cases, there seems to be no colonization of the genitals with oral microbiota.

relation to the following outcomes: 'participant-rated improvement or remission of symptoms' (risk ratio (RR) 2.85, 95% confidence interval (CI) 1.45 to 5.61) and 'investigator-rated global degree of improvement' (standardised mean difference (SMD) 5.74, 95% CI 4.26 to 7.23).When mometasone furoate 0.05% was compared to placebo in another trial, there was a significant improvement in the 'investigator-rated change in clinical grade of phimosis' (SMD -1.04, 95% CI -1.77 to -0.31).Both trials found no significant differences in reported adverse drug reactions between the corticosteroid and placebo groups. The data from four trials found no significant benefit for topical testosterone, dihydrotestosterone, and progesterone. When used as maintenance therapy after an initial treatment with topical clobetasol propionate in another trial, topical testosterone worsened the symptoms (P < 0.05), but the placebo did not.One trial found no differences between pimecrolimus and clobetasol propionate in relieving symptoms through change in pruritus (itching) (SMD -0.33, 95% CI -0.99 to 0.33) and burning/pain (SMD 0.03, 95% CI -0.62 to 0.69). However, pimecrolimus was less effective than clobetasol propionate with regard to the 'investigator-rated global degree of improvement' (SMD -1.64, 95% CI -2.40 to -0.87). This trial found no significant differences in reported adverse drug reactions between the pimecrolimus and placebo groups. The current limited evidence demonstrates the efficacy of clobetasol propionate, mometasone furoate, and pimecrolimus in treating genital lichen sclerosus. Further RCTs are needed to determine the optimal potency and regimen of topical corticosteroids, examine other topical interventions, assess the duration of remission or prevention of flares, evaluate the reduction in the risk of genital squamous cell carcinoma or genital intraepithelial neoplasia, and examine the efficacy in improving the quality of the sex lives of people with this condition.

We have attempted to discuss genital trauma in relatively broad terms. In most cases, patients present with relatively minimal trauma. However, because of the complexity of the structures involved, minimal trauma can lead to significant disability later on. The process of erection requires correct functioning of the arterial, neurologic, and venous systems coupled with intact erectile bodies. The penis is composed of structures that are compliant and distensible to the limits of their compliance. These structures therefore tumesce in equal proportion to each other, allowing for straight erection. Relatively minimal trauma can upset this balance of elasticity, leading to disabling chordee. Likewise, relatively minimal injuries to the vascular erectile structures can lead to significantly disabling spongiofibrosis. The urethra is a conduit of paramount importance. Whereas the development of stricture is generally related to the nature of the trauma, the extent of stricture and of attendant complications is clearly a function of the immediate management. Overzealous debridement can greatly complicate subsequent reconstruction. A delicate balance between aggressive initial management and maximal preservation of viable structures must be achieved. 38 references.
Introduction Warts are caused by the human papillomavirus (HPV), of which there are over 100 types. HPV probably infects the skin via areas of minimal trauma. Risk factors include use of communal showers, occupational handling of meat, and immunosuppression. In immunocompetent people, warts are harmless and resolve as a result of natural immunity within months or years. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for warts (non-genital)? We searched: Medline, Embase, The Cochrane Library, and other important databases up to October 2013 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 17 studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic, review we present information relating to the effectiveness and safety of the following interventions: intralesional bleomycin; intralesional candida antigen; contact immunotherapy; cryotherapy; duct tape occlusion; photodynamic treatment; pulsed dye laser; surgical procedures; and topical salicylic acid.

The practice of female genital mutilation (we will use the latest definition adopted by WHO/UNFP: female genital mutilation/cutting or FGM/C) is still widespread in 28 African countries. The World Health Organisation (WHO) estimates that more than two million females undergo some form of genital mutilation every year. Its negative health impact and its ethical and human rights aspects have been discussed and attempts to eliminate it have been the objectives of several meetings promoted by national and international organisations thanks to an increased awareness related to FGM/C in those countries practicing it and also, maybe due to the number of Africans migrating to industrialized countries. We review the present situation in Djibouti, a small country in the Horn of Africa, where 98 % of the female population has suffered different forms of FGM/C.

Emollients are known to lubricate, moisturize and soothe the skin. Prior to their incorporation into feminine hygiene pads, thorough premarket toxicological testing is conducted to evaluate their safety and effectiveness via in-use clinical settings. Product testing has been conducted on various body sites proven previously to be valid and reliable, such as the arm and popliteal fossa and, more recently, the genital area. Several clinical studies have confirmed the safety and efficacy of emollient-containing feminine hygiene products, which have also been shown to provide dermatological benefits in the genital area.

Male genital trauma is a rare but potentially serious sports injury. Although such an injury can occur by many different mechanisms, including falls, collisions, straddle injuries, kicks, and equipment malfunction, the clinical presentation is typically homogeneous, characterized by pain and swelling. Almost all sports-related male genital injury comes from blunt force trauma, with involvement of scrotal structures far more common than penile structures. Most injuries can be treated conservatively, but catastrophic testicular injury must first be ruled out. Despite being relatively uncommon compared with other sports injuries, more than half of all testicular injuries are sustained during sports.

The Epstein-Barr virus (EBV) is associated with a broad spectrum of diseases, mainly because of its genomic characteristics, which result in different latency patterns in immune cells and infective mechanisms. The patient described in this report is a previously healthy young man who presented to the emergency department with clinical features consistent with meningitis and genital ulcers, which raised concern that the herpes simplex virus was the causative agent. However, the polymerase chain reaction of cerebral spinal fluid was positive for EBV. The authors highlight the importance of this infection among the differential diagnosis of central nervous system involvement and genital ulceration. PMID:27547743

Objectives To evaluate the relationship of warts in different parts of the body and the risk of asymptomatic genital human papillomavirus (HPV) infection in men. Methods We examined the relationship of self-reported genital and extra-genital warts with the subsequent acquisition of asymptomatic genital HPV infection in a cohort of 331 adult men. Participants were followed at 2-month intervals for up to 4 years. Past and current presence of warts was queried at study entry. At each visit, the external genitals were sampled for HPV DNA testing. Results Men who reported a history of genital warts, including current warts, were at increased risk of acquisition of asymptomatic HPV infection of the penis glans/corona, penis shaft and scrotum. The magnitude of these associations was greatest for HPV 6/11 infection. History of warts on the fingers, arms and trunk of the body was also associated with increased risk of genital HPV infection. Current presence of warts on the fingers and trunk specifically increased the risk of acquisition of HPV types not typically found on the genitals. Conclusions Men with a history of warts on the genitals, fingers, arms and trunk may be at increased risk for acquisition of new genital HPV infections. Warts may provide an efficient reservoir for the transmission of virions to the genitals through auto-inoculation. The potential for the spread of HPV throughout the body through auto-inoculation has important implications for prevention and control of HPV infection. PMID:21602516

In Djibouti, the prevalence of female genital mutilations (FGMs) amounts to 98% and the practice is still in use. When I left, in 1999, I knew I would involve myself in the fight against FGMs and I describe here the outcome of an obstacle course of more than ten years duration. This paper is written on behalf of innumerable women, who could give you a similar account.

Current design strategies for vaccines against certain microbial pathogens, including Chlamydia trachomatis, require the induction and targeting of specific immune effectors to the local sites of infection known as the mucosal effector sites. Chemokines and their receptors are important mediators of leukocyte trafficking and of the controlled recruitment of specific leukocyte clonotypes during host defense against infections and during inflammation. We analyzed the dynamics of chemokine and chemokine receptor expression in genital mucosae during genital chlamydial infection in a murine model to determine how these molecular entities influence the development of immunity and the clearance of infection. A time course study revealed an increase of up to threefold in the levels of expression of RANTES, monocyte chemotactic protein 1 (MCP-1), gamma-interferon-inducible protein 10 (IP-10), macrophage inflammatory protein 1alpha (MIP-1alpha), and intercellular adhesion molecule type 1 (ICAM-1) after genital infection with the C. trachomatis agent of mouse pneumonitis. Peak levels of expression of RANTES, MCP-1, and MIP-1alpha occurred by day 7 after primary infection, while those of IP-10 and ICAM-1 peaked by day 21. Expression levels of these molecules decreased by day 42 after primary infection, by which time all animals had resolved the infection, suggesting an infection-driven regulation of expression. A rapid upregulation of expression of these molecules was observed after secondary infection. The presence of cells bearing the chemokine receptors CCR5 and CXCR3, known to be preferentially expressed on Th1 and dendritic cells, was also synchronous with the kinetics of immune induction in the genital tract and clearance of infection. Results demonstrated that genital chlamydial infection is associated with a significant induction of chemokines and chemokine receptors that are involved in the recruitment of Th1 cells into the site of infection. Future studies will focus

Genital allergy should be considered as a possible diagnosis in all patients with genital soreness or irritation for which no infection or dermatosis can be identified and in whom symptoms remain unchanged or worsen with treatment. It is an underreported and underdiagnosed condition as patients may not complain about symptoms in this area. Moreover, diagnosis and therapy may not often be conducted by a dermatologist or allergologist. Therefore, many cases of allergic diseases in the genital area remain undetected. PMID:27190404

In most animal groups, it is unclear how body size variation relates to genital size differences between the sexes. While most morphological features tend to scale with total somatic size, this does not necessarily hold for genitalia because divergent evolution in somatic size between the sexes would cause genital size mismatches. Theory predicts that the interplay of female-biased sexual size dimorphism (SSD) and sexual genital size dimorphism (SGD) should adhere to the 'positive genital divergence', the 'constant genital divergence', or the 'negative genital divergence' model, but these models remain largely untested. We test their validity in the spider family Nephilidae known for the highest degrees of SSD among terrestrial animals. Through comparative analyses of sex-specific somatic and genital sizes, we first demonstrate that 99 of the 351 pairs of traits are phylogenetically correlated. Through factor analyses we then group these traits for MCMCglmm analyses that test broader correlation patterns, and these reveal significant correlations in 10 out of the 36 pairwise comparisons. Both types of analyses agree that female somatic and internal genital sizes evolve independently. While sizes of non-intromittent male genital parts coevolve with male body size, the size of the intromittent male genital parts is independent of the male somatic size. Instead, male intromittent genital size coevolves with female (external and, in part, internal) genital size. All analyses also agree that SGD and SSD evolve independently. Internal dimensions of female genitalia evolve independently of female body size in nephilid spiders, and similarly, male intromittent genital size evolves independently of the male body size. The size of the male intromittent organ (the embolus) and the sizes of female internal and external genital components thus seem to respond to selection against genital size mismatches. In accord with these interpretations, we reject the validity of the

Genital morphology (especially male) among the animal kingdom is characterized by extensive differences that even members of closely related species with similar general morphology may have remarkably diverse genitalia. To present the sexual medicine specialist with a basic understanding of the current hypotheses on genital evolution with an emphasis on the sexual selection theories. A review of current literature on the theories of genital evolution. Analysis of the supporting evidence for the sexual selection theories of genital evolution. Several theories have been proposed to explain genital evolution. Currently, the sexual selection theories are being considered to present valid and solid evidence explaining genital evolution. However, other theories, including sexual conflict, are still being investigated. All theories of genital evolution have their own weaknesses and strengths. Given that many complex biological mechanisms, mostly unknown yet, are involved in the process of genital evolution, it is thus reasonable to conclude that not one theory can independently explain genital evolution. It is likely that these mechanisms may prove to have synergistic rather than exclusive effects.
Background In several species with external fertilization, including frogs, laid unfertilized eggs were found to die by apoptosis outside of the animal body. However, there is no apparent reason for the externally laid eggs to degrade by this process, considering that apoptosis developed as a mechanism to reduce the damaging effect of individual cell death to the whole organism. Results Here, we demonstrate that a number of eggs are retained in the genital tract of the African clawed frog Xenopus laevis after gonadotropin-induced ovulation. The majority of these eggs exit meiotic arrest within 24 hours of hormone administration. Subsequently, post-meiotic eggs die in the frog genital tract by a well-defined apoptotic process. The hallmarks of egg degradation include prominent morphological changes, cytochrome c release, caspase activation, increase in ADP/ATP ratio, progressive intracellular acidification, egg swelling and all-out proteolysis of egg proteins. The sustained presence of post-apoptotic eggs in the genital tract of ageing frogs evidenced age-associated worsening of apoptotic clearance. Conclusions The direct observation of egg degradation in the Xenopus genital tract provides a clue to the physiological relevance of frog egg apoptosis.

Depot-medroxyprogesterone acetate (DMPA) is a hormonal contraceptive especially popular in areas with high prevalence of HIV and other sexually transmitted infections (STI). While observational studies identify DMPA as an important STI risk factor, mechanisms underlying this connection are undefined. Levonorgestrel (LNG) is another progestin used for hormonal contraception, but its effect on STI susceptibility is much less explored. Using a mouse model of genital HSV-2 infection, we herein found DMPA and LNG similarly reduced genital expression of the desmosomal cadherin desmoglein-1α (DSG1α), enhanced access of inflammatory cells to genital tissue by increasing mucosal epithelial permeability, and increased susceptibility to viral infection. Additional studies with uninfected mice revealed DMPA-mediated increases in mucosal permeability promoted tissue inflammation by facilitating endogenous vaginal microbiota invasion. Conversely, concomitant treatment of mice with DMPA and intravaginal estrogen restored mucosal barrier function and prevented HSV-2 infection. Evaluating ectocervical biopsy tissue from women before and 1 month after initiating DMPA remarkably revealed inflammation and barrier protection were altered by treatment identically to changes seen in progestin-treated mice. Together, our work reveals DMPA and LNG diminish the genital mucosal barrier; a first-line defense against all STI, but may offer foundation for new contraceptive strategies less compromising of barrier protection.

Male salamanders use nephrons from the genital kidney to transport sperm from the testicular lobules to the Wolffian duct. The microstructure of the epithelia of the genital kidney proximal tubule and distal tubule was studied over 1 year in a population of Notophthalmus viridescens from Crawford and Pike counties in central Missouri. Through ultrastructural analysis, we were able to support the hypothesis that the genital kidney nephrons are modified to aid in the transportation of sperm. A lack of folding of the basal plasma membrane, in both the genital kidney proximal and distal tubules when compared to the pelvic kidney proximal and distal tubules, reduces the surface area and thus likely decreases the efficiency of reabsorption in these nephron regions of the genital kidney. Ciliated epithelial cells are also present along the entire length of the genital kidney proximal tubule, but are lacking in the epithelium of the pelvic kidney proximal tubule. The exact function of these cilia remains unknown, but they may aid in mixing of seminal fluids or the transportation of immature sperm through the genital kidney nephrons. Ultrastructural analysis of proximal and distal tubules of the genital kidney revealed no seasonal variation in cellular activity and no mass production of seminal fluids throughout the reproductive cycle. Thus, we failed to support the hypothesis that the cellular activity of the epithelia lining the genital kidney nephrons is correlated to specific events in the reproductive cycle. The cytoplasmic contents and overall structure of the genital and pelvic kidney epithelial cells were similar to recent observations in Ambystoma maculatum, with the absence of abundant dense bodies apically in the epithelial cells lining the genital kidney distal tubule.

Genital surgery is performed at the final stage of the gender reassignment process and is in Finland by statutory regulation of 2003 concentrated to be carried out by the HUCH multiprofessional team. Statutory recommendations from the psychiatry units at both HUCH and Tays Central Hospital are required for this. Sex reassignment surgery will be undertaken on the basis of a steadfast wish of an adult patient on the condition that he/she understands the risks associated with surgery and is mentally and physically fit for the operation.

Female genital cutting (FGC) is a practice that affects millions of girls and women worldwide. This deeply rooted practice has cultural, religious, and psychosexual meaning to its practitioners, but it also carries long-term physical and mental complications. Decried as a human rights violation, nonetheless this practice is still carried out today. Nurses are in a unique position to contact and educate women who have been cut or are at risk for mutilation. To advocate for these women, a thorough understanding of the practice of FGC, its cultural overtones, religious implications, and psychosexual effects is needed.
Melanocytic lesions of the genital area are rare. They arise mainly in the vulva, although they can also occur less frequently in the perineum, mons pubis and male genitalia and represent 10-12% of pigmented lesions of White women. These pigmented lesions include melanocytic nevi, lentigines, melanocytic nevi with architectural disorder and atypia of melanocytes (dysplastic nevi) and melanomas with microscopic features similar to those seen elsewhere on the body. There is a small subset of benign nevi named atypical melanocytic nevi of the genital type (AMNGT) that occur in young women, with distinctive histologic features in some cases overlapping morphologically with those of melanoma. Thus, it is important to distinguish AMNGT from melanomas in terms of prognosis and treatment. We retrieved 58 cases of genital pigmented lesions diagnosed at our hospital from 1986 to 2008 to evaluate their clinicopathologic features with especial consideration to those cases with atypical features. Thirty-two cases (55%) were common nevi, 10 (17%) lentigines, 6 (10%) melanomas, 3 (5%) dysplastic nevi and 1 blue nevus. Six cases (10%) corresponded to AMNGT and were taken from women with a median age of 21 years. All cases showed symmetry, and the melanocytic proliferation was well demarcated at the lateral margins. The junctional component was very prominent and formed by round or fusiform nests with common retraction artifact and/or cellular dyshesion or as a single cell proliferation with mild (33%) to moderate (67%) cytologic atypia, focal pagetoid spread (17%) and a benign-appearing dermal component (83%) with maturation and dense eosinophilic fibrosis in the superficial dermis. Neither nuclear atypia of melanocytes in the superficial dermis nor dermal mitoses were observed. AMNGT were excised, and no recurrences were recorded in the follow up (median 10.5 years). Therefore, it seems that there is no evidence that AMNGT are precursors of dysplastic nevi or melanomas.

Genital herpes is a common sexually transmitted infection. In reproductive age it involves the additional risk of vertical transmission to the neonate. Rates of transmission are affected by the viral type and whether the infection around delivery is primary or recurrent. Neonatal herpes is a rare but very severe complication of genital herpes infection and is caused by contact with infected genital secretions at the time of labor. Maternal acquisition of herpes simplex virus (HSV) in the third trimester of pregnancy carries the highest risk of neonatal transmission. Prevention of neonatal herpes depends on preventing acquisition of genital HSV infection during late pregnancy and avoiding exposure of the infant to herpetic lesions during delivery. Uninfected woman should be counselled about the need of avoiding sexual contact during the third trimester. Elective caesarean section before the onset of labor is the choice mode of delivery for women with genital lesions or with prodromal symptoms near the term, even if it offers only a partial protection against neonatal infection. Antiviral suppressive therapy is used from 36 weeks of gestation until delivery in pregnant women with recurrences to prevent genital lesions at the time of labor so reducing the need of caesarean sections. Currently, routine maternal serologic screening is not yet recommended. Because most mothers of infants who acquire neonatal herpes lack histories of clinically evident genital herpes, researchers should focus on the recognition of asymptomatic primary genital HSV infections.

Despite the high prevalence of genital pain in healthy young adult women, limited research has addressed genital pain during intercourse using contemporary models of multidimensional sexual function. The objectives of this study were threefold: (1) to identify differences in sexual functioning in women who experience genital pain compared to pain free women; (2) to identify predictors of sexual functioning in women with and without genital pain; and (3) to identify predictors of sexual satisfaction in women with and without genital pain. Sexually active female undergraduates (n = 651) were administered the Female Sexual Function Index and the Derogatis Sexual Functioning Inventory. We evaluated the sexual factors that impact the sexual function of women with any pain (including high and low pain groups) versus women with no history of pain. Women with genital pain reported greater rates of sexual dysfunction as compared to pain-free women; however, sexual functioning in the high versus low pain groups was distinguished primarily by vaginal lubrication. Women in the high pain group showed negative correlations between domains of sexual satisfaction and genital pain frequency and intensity that were not found in the low pain group. For pain-free women, intercourse played a strong role in sexual satisfaction, whereas non-intercourse sexual behavior was central to sexual satisfaction in women who reported pain. The evaluation of levels of genital pain may provide insight into the mechanisms underlying the impairment of sexual function, sexual behavior, and sexual satisfaction. PMID:17674182
Background Human papillomaviruses are the most common sexually transmitted infections, and genital warts, caused by HPV-6 and 11, entail considerable morbidity and cost. The natural history of genital warts in relation to HIV-1 infection has not been described in African women. We examined risk factors for genital warts in a cohort of high-risk women in Burkina Faso, in order to further describe their epidemiology. Methods A prospective study of 765 high-risk women who were followed at 4-monthly intervals for 27 months in Burkina Faso. Logistic and Cox regression were used to identify factors associated with prevalent, incident and persistent genital warts, including HIV-1 serostatus, CD4+ count, and concurrent sexually transmitted infections. In a subset of 306 women, cervical HPV DNA was tested at enrolment. Results Genital wart prevalence at baseline was 1.6% (8/492) among HIV-uninfected and 7.0% (19/273) among HIV-1 seropositive women. Forty women (5.2%) experienced at least one incident GW episode. Incidence was 1.1 per 100 person-years among HIV-uninfected women, 7.4 per 100 person-years among HIV-1 seropositive women with a nadir CD4+ count >200 cells/μL and 14.6 per 100 person-years among HIV-1 seropositive women with a nadir CD4+ count ≤200 cells/μL. Incident genital warts were also associated with concurrent bacterial vaginosis, and genital ulceration. Antiretroviral therapy was not protective against incident or persistent genital warts. Detection of HPV-6 DNA and abnormal cervical cytology were strongly associated with incident genital warts. Conclusions Genital warts occur much more frequently among HIV-1 infected women in Africa, particularly among those with low CD4+ counts. Antiretroviral therapy did not reduce the incidence or persistence of genital warts in this population. PMID:21251265

Neuroendocrine tumours are uncommon or rare at all sites in the female genital tract. The 2014 World Health Organisation (WHO) Classification of neuroendocrine tumours of the endometrium, cervix, vagina and vulva has been updated with adoption of the terms low-grade neuroendocrine tumour and high-grade neuroendocrine carcinoma. In the endometrium and cervix, high-grade neoplasms are much more prevalent than low-grade and are more common in the cervix than the corpus. In the ovary, low-grade tumours are more common than high-grade carcinomas and the term carcinoid tumour is still used in WHO 2014. The term ovarian small-cell carcinoma of pulmonary type is included in WHO 2014 for a tumour which in other organs is termed high small-cell neuroendocrine carcinoma. Neuroendocrine tumours at various sites within the female genital tract often occur in association with other neoplasms and more uncommonly in pure form.

Few meeting participants envisioned a prevention and control program on the scale or scope of CDC's programs to prevent HIV infection, syphilis, gonorrhea, and chlamydial infection, but all agreed that the virtual absence of public health interventions to prevent genital herpes is no longer appropriate in light of evolving epidemiologic knowledge and other research advances. The ultimate scope of a national genital herpes prevention effort will depend in part on the results of the recommended research agenda, which probably will evolve over the better part of a decade. Numerous other STD prevention partners will also need to contribute to this effort and help to determine the makeup of future programs. Substantial new fiscal resources will be required both to implement the proposed research agenda and, depending on the results, to undertake the prevention efforts indicated by those studies. Competing STD prevention priorities and other national health needs will influence the availability of those resources. The consultants' meeting and the research and program activities summarized above are described in more detail in the full meeting report, which is posted on the Division's web site (www.cdc.gov/nchstp/dstd/dstdp.html) or may be requested directly from the Division. DSTDP is interested in receiving comments and suggestions about herpes prevention.
As one of the most common sexually transmitted diseases, genital herpes is a global medical problem with significant physical and psychological morbidity. Genital herpes is caused by herpes simplex virus type 1 or type 2 and can manifest as primary and/or recurrent infection. This manuscript provides an overview about the fundamental knowledge on the virus, its epidemiology, and infection. Furthermore, the current possibilities of antiviral therapeutic interventions and laboratory diagnosis of genital herpes as well as the present situation and perspectives for the treatment by novel antivirals and prevention of disease by vaccination are presented. Since the medical management of patients with genital herpes simplex virus infection is often unsatisfactory, this review aims at all physicians and health professionals who are involved in the care of patients with genital herpes. The information provided would help to improve the counseling of affected patients and to optimize the diagnosis, treatment, and prevention of this particular disease.

Type I interferons (IFNs) induced during in vitro chlamydial infection exert bactericidal and immunomodulatory functions. To determine the precise role of type I IFNs during in vivo chlamydial genital infection, we examined the course and outcome of Chlamydia muridarum genital infection in mice genetically deficient in the receptor for type I IFNs (IFNAR(-/-) mice). A significant reduction in chlamydial shedding and duration of lower genital tract infection was observed in IFNAR(-/-) mice in comparison to the level of chlamydial shedding and duration of infection in wild-type (WT) mice. Furthermore, IFNAR(-/-) mice developed less chronic oviduct pathology in comparison to that in WT mice. Compared to the WT, IFNAR(-/-) mice had a greater number of chlamydial-specific T cells in their iliac lymph nodes 21 days postinfection. IFNAR(-/-) mice also exhibited earlier and enhanced CD4 T-cell recruitment to the cervical tissues, which was associated with increased expression of CXCL9 in the genital secretions of IFNAR(-/-) mice, but not with expression of CXCL10, which was reduced in the genital secretions of IFNAR(-/-) mice. These data suggest that type I IFNs exacerbate C. muridarum genital infection through an inhibition of the chlamydial-specific CD4 T-cell response.

Genital chronic graft-versus-host disease (GVHD) is a frequent but underdiagnosed complication of allogeneic stem-cell transplantation impairing quality of life. We identified 32 female patients with genital chronic GVHD (cGVHD) who underwent allogeneic hematopoietic stem-cell transplantation in our center between 2000 and 2010 and who were followed after transplantation in a specialized gynecological consultation. Pre- and posttransplantation clinical data and detailed acute and cGVHD data were collected. All patients received the same local treatment for genital lesions. At presentation, most patients complained about vaginal dryness and dyspareunia with impairment in sexual activity. Fifty percent of patients had grade I genital lesions and 50% had grade II or III lesions. Patients seen later in gynecological consultation had more severe lesions than patients seen early after transplantation. At the time of diagnosis, most patients had other cutaneous or mucous localizations of cGVHD. In most cases, lesions were stabilized or decreased with local steroids and estrogen treatment, and most patients could resume sexual activity. Treatment was more efficient in patients with mild lesions than in others. Genital cGVHD should be systematically searched for in women who have received allogeneic hematopoietic stem-cell transplantation in an early specialized consultation, especially in case of other cutaneous or mucous localizations of cGVHD. Local treatment associating steroids and estrogen seemed to prevent further evolution of grade I genital lesions and to avoid surgical treatment.

Genital herpes is an incurable, chronic disease that affects millions of people worldwide. Not only does genital herpes cause painful, recurrent symptoms, it is also a significant risk factor for the acquisition of other sexually transmitted infections such as HIV-1. Antiviral drugs are used to treat herpes simplex virus (HSV) infection, but they cannot stop viral shedding and transmission. Thus, developing a vaccine that can prevent or clear infection will be crucial in limiting the spread of disease. In this review we outline recent studies that improve our understanding of host responses against HSV infection, discuss past clinical vaccine trials, and highlight new strategies for vaccine design against genital herpes.

Lipschütz acute genital ulcer is a rare distinctive cause of nonvenereal acute genital ulcers that occurs particularly in adolescents described in 1913. We report here a typical case that occurred in a 24-year-old virgin woman who developed flu-like symptoms and painful genital ulcers that healed spontaneously within a week and without any infection (Epstein Barr Virus, toxoplasmosis, salmonella). The physiopathogeny remains unknown. However, there are body of evidences pointing out a possible link to several nonvenereal infections, including mainly Epstein-Barr virus acute infection. This rare benign but disabling entity should be known by gynecologists.

CD161 identifies a subset of circulating Th17 cells that are depleted in the blood and gut of HIV-infected individuals. In the female reproductive tract (FRT), the pattern of CD161 expression on CD4(+) cells remains unknown. Here, we characterized CD161 expression in the FRT of Kenyan female sex workers (FSW). Compared to the blood, CD161(+)CD4(+) T cells were enriched in the FRT of uninfected FSWs. These cells were depleted in FRT of HIV-infected FSWs. Cervical CD161(+) cells harboured an activated phenotype (CD69, CD95, HLA-DR) with elevated expression of tissue-homing markers (CCR6, β7 integrin) and HIV co-receptor (CCR5). Mitogen-stimulated production of IL-17 confirmed the Th17 commitment of CD161(+)CD4(+) T cells in the FRT with a predominance of polyfunctional Th1/Th17 cells. Here, we showed that the expression of CD161 on CD4+T cells is modulated at the FRT, but still identified a highly activated cellular subset, which differentiates into pro-inflammatory Th1/Th17 cells, expresses multiple HIV susceptibility markers and are depleted in HIV-infected individuals. The use of CD161 as a biomarker of HIV targets in the FRT reduces the need for functional assessment of cells and could have important implications in better understanding HIV pathogenesis and Th17 fate in the FRT of high-risk women.

Lymphatic malformation or lymphangioma is a benign proliferation of the lymphatics accounting for 4% of all vascular malformations and 26% of all benign vascular tumors. There are several reports about genital lymphangiomas mimicking venereal lesions, such as genital warts. Hereby we described a case of a 24 year old man affected by multiple vesicles and warts in genital area. All hematological and biochemical parameters, Human Immunodeficiency Virus (HIV) and Treponema Pallidum tests, C1-Inhibitor and C1-Q values were within limits. An accurate fulguration and wide excision of bigger lesions were performed. Histological examination showed numerous dilated lymphatic vessels in the superficial dermis with infiltration of inflammatory cells, that is a histopathological picture compatible with genital lymphangioma. Considering our clinical suspicion of condylomatosis, HPV (Human Papilloma Virus) Polimerase Chain Reaction (PCR) Genotyping, named INNOLiPA test, was performed, that revealed a genital infection by HPV - genotype 6. We think that our case can be considered an example of HPV infection and acquired genital lymphangioma overlap clinical syndrome. The patient presented any lesions one year after the procedure at follow-up examination.

Genital herpes simplex virus type 2 (HSV-2) infection causes recurrent lesions and frequent viral shedding. GEN-003 is a candidate therapeutic vaccine containing HSV-2 gD2∆TMR and ICP4.2, and Matrix-M2 adjuvant. Persons with genital herpes were randomized into 3 dose cohorts to receive 3 intramuscular doses 21 days apart of 10 µg, 30 µg, or 100 µg of GEN-003, antigens without adjuvant, or placebo. Participants obtained genital swab specimens twice daily for HSV-2 detection and monitored genital lesions for 28-day periods at baseline and at intervals after the last dose. One hundred and thirty-four persons received all 3 doses. Reactogenicity was associated with adjuvant but not with antigen dose or dose number. No serious adverse events were attributed to GEN-003. Compared with baseline, genital HSV-2 shedding rates immediately after dosing were reduced with GEN-003 (from 13.4% to 6.4% for 30 μg [P < .001] and from 15.0% to 10.3% for 100 µg [P < .001]). Lesion rates were also significantly (P < .01) reduced immediately following immunization with 30 µg or 100 µg of GEN-003. GEN-003 elicited increases in antigen binding, virus neutralizing antibody, and T-cell responses. GEN-003 had an acceptable safety profile and stimulated humoral and cellular immune responses. GEN-003 at doses of 30 µg and 100 µg reduced genital HSV shedding and lesion rates. NCT01667341 (funded by Genocea).
The increasing incidence of human papillomavirus (HPV) infection and HPV-associated conditions such as genital warts in women is a global concern. Genital warts are a clinical manifestation of HPV types 6 and 11, and are estimated to affect 1% of sexually active adults aged between 15 and 49. HPV infection is also strongly associated with cervical cancer, and is prevalent in as many as 99% of cases. The psychological stress of having genital warts is often greater than the morbidity of the disease, and therefore successful treatment is crucial. Current treatments are patient-applied and provider-administered therapies. Imiquimod 5% cream, a patient-applied therapy, is an efficacious treatment with tolerable side-effects and a low recurrence rate, and has the potential to be an effective strategy for the management of genital warts.

Genital leiomyoma in men include those superficial leiomyomas arising in the scrotum and the areola. They are unusual neoplasms: few cases have been reported in the literature and they usually escape clinical diagnosis. Three cases of male genital leiomyomas are reported: two in the scrotum and one in the areola. They were all conservatively excised and the behaviour was completely benign in all cases. Histopathological examination showed the typical findings of superficial leiomyomas, with some minor differences between cases arising in the scrotum and those from the areola. Immunohistochemical findings not only confirmed the smooth muscle nature of all cases but also showed unequivocal immunostaining for androgen receptors in the leiomyomas from the scrotum. Immunostaining for androgen receptors in scrotal leiomyomas is, as far as we are aware, a previously unknown characteristic of male genital leiomyomas. This finding supports the role of steroid hormones in the growth of genital leiomyomas, similar to leiomyomas found in other locations.

Although Chlamydia infections are widespread throughout the world, data about immunopathogenesis of genitourinary tract infections in males are very limited. In the present work we present an in vitro model of male genital tract-derived epithelial cells, more precisely prostate epithelial cells (PEC), to analyze if they are susceptible and able to respond to Chlamydia muridarum infection. Our results demonstrate that rat PEC are susceptible to C. muridarum infection and respond to this pathogen by up-regulating different proinflammatory cytokine and chemokine genes that could participate in the recruitment and local activation of immune cells, therefore influencing innate and adaptive immune responses during Chlamydia infection. Moreover, we analyzed the expression of Toll-like receptor 4 (TLR4), TLR2, and related molecules on PEC and the effect of C. muridarum infection on their expression. Our results demonstrate that PEC express significant levels of TLR4, CD14, TLR2, and the adaptor molecule MyD88 and up-regulate these proteins in response to C. muridarum infection. Indeed, TLR4, CD14, TLR2, and the adaptor MyD88 are specifically recruited to the vicinity of the bacterial inclusion, suggesting that these TLRs are actively engaged in signaling from this intracellular location in these cells. This is, to our knowledge, the first time that an in vitro model of infection with Chlamydia of male tract-derived epithelial cells has been achieved, and it provides the opportunity to determine how these cells respond and participate in modulating innate and adaptive immune response during Chlamydia infections.

Chlamydia trachomatis genital infection is the most common sexually transmitted bacterial disease, causing a significant burden to females due to reproductive dysfunction. Intensive screening and antibiotic treatment are unable to completely prevent female reproductive dysfunction, thus, efforts have become focused on developing a vaccine. A major impediment is identifying a safe and effective adjuvant which induces cluster of differentiation 4 (CD4) cells with attributes capable of halting genital infection and inflammation. Previously, we described a natural nanocapsule called the vault which was engineered to contain major outer membrane protein (MOMP) and was an effective vaccine which significantly reduced early infection and favored development of a cellular immune response in a mouse model. In the current study, we used another chlamydial antigen, a polymorphic membrane protein G-1 (PmpG) peptide, to track antigen-specific cells and evaluate, in depth, the vault vaccine for its protective capacity in the absence of an added adjuvant. We found PmpG-vault immunized mice significantly reduced the genital bacterial burden and histopathologic parameters of inflammation following a C. muridarum challenge. Immunization boosted antigen-specific CD4 cells with a multiple cytokine secretion pattern and reduced the number of inflammatory cells in the genital tract making the vault vaccine platform safe and effective for chlamydial genital infection. We conclude that vaccination with a Chlamydia-vault vaccine boosts antigen-specific immunities that are effective at eradicating infection and preventing reproductive tract inflammation.

Chlamydia trachomatis is the most common cause of curable bacterial sexually transmitted infection (STI) worldwide. It manifests primarily as urethritis in males and endocervicitis in females. Untreated chlamydial infection in man can cause epididymitis and proctitis. Though most women with Chlamydia infection are asymptomatic or have minimal symptoms, some develop salpingitis, endometritis, pelvic inflammatory disease (PID), ectopic pregnancy and tubal factor infertility. It is associated with an increased risk for the transmission or acquisition of HIV and is also attributed to be a risk factor for the development of cervical carcinoma. Early diagnosis and treatment of infected individuals is required to prevent the spread of the disease and severe sequelae. Traditionally, tissue culture was considered the gold standard for the diagnosis. However, with the availability of newer diagnostic techniques particularly molecular methods which are not only highly sensitive and specific but are cost-effective also, the diagnosis has became fast and easy. The purpose of this review is to study the various aspects of genital C. trachomatis infection. Also the advances related to the clinical picture, various diagnostic modalities, prevention, treatment, drug resistance and control measures will be dealt with. PMID:24135174
As immigrant women from African countries enter the U.S., Canada, Australia, and Western Europe, western health care providers are beginning to see patients affected by the cultural practice of Female Genital Mutilation (FGM). Unfamiliar with the practice, either medically or culturally, these providers are turning to medical librarians for information. Complicating the issue are the strong negative feelings most western health care workers have about FGM, which appears to them to be both barbaric and cruel. These feelings may conflict strongly with those of their immigrant patients, who regard the practice as normal and desirable. Both medical and cultural information are needed for the professional to provide treatment of medical conditions, while also establishing a good relationship with the FGM affected patient. This article identifies and describes the most important refereed journal article databases, available now over the Internet, providing both medical and cultural information on FGM, and the most useful Web sites for health professionals, librarians, and interested laypersons who need information about this difficult multicultural issue.

Background: Nonvenereal dermatoses tend to create confusion from venereal dermatoses. This may be responsible for considerable concern to the patient as well as may cause diagnostic dilemma to the physicians. Nonvenereal dermatoses may not be restricted to genitalia alone; it may affect skin and mucous membrane also. Most of the patients with genital lesions had apprehension of suffering from some venereal disorders. Aim: The aim was to determine clinical and epidemiological pattern of nonvenereal dermatoses of male external genitalia. Materials and Methods: This was a descriptive study of 100 consecutive adult male patients with nonvenereal genital dermatoses attending skin and STD OPD at J A Group of Hospitals, Gwalior. Cases having any venereal dermatoses were excluded from this study. Results: The study included 100 male patients with nonvenereal genital lesions. A total of sixteen nonvenereal genital dermatoses were noted. The most common nonvenereal genital dermatoses were vitiligo (18%), pearly penile papule (16%), fixed drug eruptions (12%), scabies (10%), scrotal dermatitis (9%) and lichen planus (9%). Other dermatoses included sebaceous cyst, psoriasis, lichen sclerosus, plasma cell balanitis or Zoon's balanitis, granuloma annulare, lichen nitidus, lymphangioma circumscriptum, papulo-necrotic tuberculid, squamous cell carcinoma and tinea infections. The age ranged from 18 years to 65 years with majority in the age group of 21-30 years (40%). Conclusion: This study highlights the importance of diagnosing common nonvenereal genital dermatoses. It also helps in avoiding the general misconception that all genital lesions are sexually transmitted. PMID:26396448

The aim of the present study was to investigate the effects of Longdanxiegan formula granule (LDXGFG), a Chinese traditional medicine on Toll-like receptor (TLR) pathway in recurrent genital herpes. An experimental recurrent genital herpes model was constructed using herpes guinea pig model. The effect of LDXGFG on expression levels of TLR pathway genes were detected using real-time polymerase chain reaction. Furthermore, the dendritic cells and Langerhans cells were isolated and the TLR pathway genes of these cells were assayed after LDXGFG treatment. The result suggested two different expression patterns of TLR pathway genes in genital herpes and recurrent genital herpes, including upregulated genes and downregulated genes. TLR1, TLR4, TLR6, TLR7, TLR8, TLR9, and TLR10 showed a significant decrease while, TLR2, TLR3, and TLR5 increased in genital herpes and recurrent genital herpes guinea pigs. Meanwhile, the downregulated genes in genital herpes and recurrent genital herpes were stimulated by LDXGFG. By contrast, the upregulated genes decreased significantly after LDXGFG treatment. In both dendritic cells and Langerhans cells, the TLR pathway genes exhibited same pattern: the LDXGFG corrected the abnormal expression of TLR pathway genes. The present results suggest that LDXGFG is an alternative, inexpensive, and lasting-effect medicine for herpes simplex virus 2 infection. Copyright © 2016. Published by Elsevier B.V.

Sexually transmitted diseases constitute major health issues and their prevention and treatment continue to challenge the health care systems worldwide. Animal models are essential for a deeper understanding of the diseases and the development of safe and protective vaccines. Currently a good predictive non-rodent model is needed for the study of genital chlamydia in women. The pig has become an increasingly popular model for human diseases due to its close similarities to humans. The aim of this review is to compare the porcine and human female genital tract and associated immune system in the perspective of genital Chlamydia infection. The comparison of women and sows has shown that despite some gross anatomical differences, the structures and proportion of layers undergoing cyclic alterations are very similar. Reproductive hormonal cycles are closely related, only showing a slight difference in cycle length and source of luteolysing hormone. The epithelium and functional layers of the endometrium show similar cyclic changes. The immune system in pigs is very similar to that of humans, even though pigs have a higher percentage of CD4(+)/CD8(+) double positive T cells. The genital immune system is also very similar in terms of the cyclic fluctuations in the mucosal antibody levels, but differs slightly regarding immune cell infiltration in the genital mucosa - predominantly due to the influx of neutrophils in the porcine endometrium during estrus. The vaginal flora in Göttingen Minipigs is not dominated by lactobacilli as in humans. The vaginal pH is around 7 in Göttingen Minipigs, compared to the more acidic vaginal pH around 3.5-5 in women. This review reveals important similarities between the human and porcine female reproductive tracts and proposes the pig as an advantageous supplementary model of human genital Chlamydia infection.

Genital gender affirming surgery (GAS) involves reconstruction of the genitals to match a patient’s identified sex. The use of hair-bearing flaps in this procedure may result in postoperative intra-vaginal and intra-urethral hair growth and associated complications, including lower satisfaction with genital GAS. Despite the significant increase in genital GAS within the past 50 years, there is limited data regarding hair removal practices in preparation for genital GAS and notable variation in hair removal techniques among dermatologists and other practitioners. We present a literature review, recommendations from our experience, and a practical laser hair removal (LHR) approach to hair removal prior to genital GAS. PMID:27298787

Infectious agents can impair various important human functions, including reproduction. Bacteria, fungi, viruses and parasites are able to interfere with the reproductive function in both sexes. Infections of male genito-urinary tract account for about 15% of the case of male infertility. Infections can affect different sites of the male reproductive tract, such as the testis, epididymis and male accessory sex glands. Spermatozoa themselves subsequently can be affected by urogenital infections at different levels of their development, maturation and transport. Among the most common microorganisms involved in sexually transmitted infections, interfering with male fertility, there are the Chlamydia trachomatis and Neisseria gonorrhoeae. Less frequently male infertility is due to non-sexually transmitted epididymo-orchitis, mostly caused by Escherichia coli. In female, the first two microorganisms are certainly involved in cervical, tubal, and peritoneal damage, while Herpes simplex cervicitis is less dangerous. The overall importance of cervical involvement is still under discussion. Tubo-peritoneal damage seems to be the foremost manner in which microorganisms interfere with human fertility. C. trachomatis is considered the most important cause of tubal lacerations and obstruction, pelvic inflammatory disease (PID) and adhesions. N. gonorrhoeae, even though its overall incidence seems to decline, is still to be considered in the same sense, while bacterial vaginosis should not be ignored, as causative agents can produce ascending infections of the female genital tract. The role of infections, particularly co-infections, as causes of the impairment of sperm quality, motility and function needs further investigation. Tropical diseases necessitate monitoring as for their diffusion or re-diffusion in the western world.

OBJECTIVE: To provide an update on new diagnostic tests and antiviral strategies for managing genital herpes. QUALITY OF EVIDENCE: Treatment guidelines are based on randomized clinical trials and recommendations from the Expert Working Group on Canadian Guidelines for Sexually Transmitted Diseases. Recommendations concerning other aspects of managing genital herpes (e.g., indications for using type-specific serologic tests) are mainly based on expert opinion. MAIN MESSAGE: Genital herpes is one of the most common sexually transmitted diseases, affecting about 20% of sexually active people; up to 80% of cases are undiagnosed. Because of frequent atypical presentation and the emotional burden associated with genital herpes, clinical diagnosis should be confirmed by viral culture. Type-specific serologic assays are now available, but their use is often restricted to special situations and requires adequate counseling. New antivirals (valacyclovir and famciclovir) with improved pharmacokinetic profiles have now been approved for episodic treatment of recurrences and suppressive therapy. CONCLUSION: Wise use of new diagnostic assays for herpes simplex coupled with more convenient treatment regimens should provide better management of patients with genital herpes.

Genital elephantiasis is an important medical problem in the tropics. It usually affects young and productive age group, and is associated with physical disability and extreme mental anguish. The majority of cases are due to filariasis; however, a small but significant proportion of patients develop genital elephantiasis due to bacterial sexually transmitted infections (STIs), mainly lymphogranuloma venereum (LGV) and donovanosis. STI-related genital elephantiasis should be differentiated from elephantiasis due to other causes, including filariasis, tuberculosis, haematological malignancies, iatrogenic, or dermatological diseases. Laboratory investigations like microscopy of tissue smear and nucleic acid amplification test for donovanosis, and serology and polymerase chain reaction for LGV may help in the diagnosis, but in endemic areas, in the absence of laboratory facilities, diagnosis largely depends on clinical characteristics. The causative agent of LGV, Chlamydia trachomatis serovar L1-L3, is a lymphotropic organism which leads to the development of thrombolymphangitis and perilymphangitis, and lymphadenitis. Long-standing oedema, fibrosis and lymphogranulomatous infiltration result in the final picture of elephantiasis. Elephantiasis in donovanosis is mainly due to constriction of the lymphatics which are trapped in the chronic granulomatous inflammatory response generated by the causative agent, Calymmatobacterium (Klebsiella) granulomatis. The LGV-associated genital elephantiasis should be treated with a prolonged course of doxycycline given orally, while donovanosis should be treated with azithromycin or trimethoprim-sulphamethoxazole combination given for a minimum of three weeks. Genital elephantiasis is not completely reversible with medical therapy alone and often needs to be reduced surgically.

Provoked vestibulodynia (PVD) is characterized by the presence of vulvar touch and pain hypersensitivity. Pain with vaginal distension, which motivates treatment seeking and perpetuates distress, is frequently reported with PVD. However, the concordance between the perception of vulvar and vaginal sensation (ie, somatic and visceral genital sensations, respectively) remains unstudied in healthy women, as well as in clinical populations such as PVD. To evaluate the static and dynamic (time-varying) properties of somatic and visceral genital sensation, women with PVD (n=14) and age- and contraceptive-matched healthy controls (n=10) rated varying degrees of nonpainful and painful genital stimulation. Somatic (vulvar) mechanical sensitivity to nonpainul and painful degrees of force were compared to visceral (vaginal) sensitivity to nonpainful and painful distension volumes. Results indicated that healthy women showed substantial individual variation in and high discrimination of vulvar and vaginal sensation. In contrast, PVD was associated with vulvar allodynia and hyperalgesia, as well as vaginal allodynia. Modeling of dynamic perception revealed novel properties of abnormal PVD genital sensation, including temporal delays in vulvar touch perception and reduced perceptual thresholds for vaginal distension. The temporal properties and magnitude of PVD distension pain were indistinguishable from vaginal fullness in healthy controls. These results constitute the first empirical comparison of somatic and visceral genital sensation in healthy women. Findings provide novel insights into the sensory abnormalities that characterize PVD, including an experimental demonstration of visceral allodynia. This investigation challenges the prevailing diagnostic assessment of PVD and reconceptualizes PVD as a chronic somatic and visceral pain condition.

Haemophilus ducreyi causes genital ulceration (chancroid), a sexually transmitted infection and still an important factor which contributes to the spread of HIV in developing countries. The bacterium produces a cytolethal distending toxin (HdCDT) causing cell cycle arrest and apoptosis/necrosis of human cells and contributes to the aggravation of ulcers. The aim of the study was to induce toxin-neutralizing antibodies in the genital tract of mice. Repeated subcutaneous (sc) immunisations with 5-10microg active HdCDT induced low levels of serum anti-HdCDT IgG without neutralizing capacity. High levels of specific IgG1 antibodies in serum and genital tract were generated after sc immunisations with 10microg formaldehyde detoxified HdCDT toxoid alone and the addition of aluminium salts or RIBI (based on the lipid A moiety) as adjuvant further increased the level of serum antibodies. A high correlation was found between elevated levels of anti-HdCDT IgG in sera, the level of neutralizing activity and the antibody level in genital tract (r=0.8). Thus, induction of high antibody levels specific to HdCDT in the genital tissue can be achieved by parenteral immunisation with the toxoid. The HdCDT toxoid can be considered as a candidate component in vaccine against chancroid.

Colonization of the female lower genital tract with Lactobacillus provides protection against STIs and adverse pregnancy outcomes. Growth of genital Lactobacillus is postulated to depend on epithelial cell-produced glycogen. However, the amount of cell-free glycogen in genital fluid available for utilization by Lactobacillus is not known. Eighty-five genital fluid samples from 7 pre-menopausal women taken over 4-6 weeks were obtained using the Instead SoftCup® (EvoFem, Inc., San Diego, CA, USA) by consented donors. Cell-free glycogen and glucose in genital fluids and estrogen and progesterone in blood were quantified. Glycogen ranged from 0.1-32 μg/μl. There were significant differences between women in glycogen over the observation period. There was a strong negative correlation between glycogen and vaginal pH (r = -0.542, p<0.0001). In multivariable analysis, free glycogen levels were significantly negatively associated with both vaginal pH and progesterone (p < 0.001 and p = 0.004, respectively). Estrogen, glucose, age, sexual intercourse 24 hours prior to visit, and days after the initial visit were not significantly associated with free glycogen levels. Cell-free glycogen concentrations can be very high, up to 3% of genital fluid, and are strongly associated with acidic vaginal pH. However, the fluctuations in glycogen levels in individuals and differences between individuals do not appear to be associated with estrogen.

Herpes simplex virus 2 (HSV-2) is a DNA virus that is efficiently transmitted through intimate genital tract contact and causes persistent infection that cannot be eliminated. HSV-2 may cause frequent, symptomatic self-limited genital ulcers, but in most persons infection is subclinical. However, recent studies have demonstrated that the virus is frequently shed from genital surfaces even in the absence of signs or symptoms of clinical disease and that the virus can be transmitted during these periods of shedding. Furthermore, HSV-2 shedding is detected throughout the genital tract and may be associated with genital tract inflammation, which likely contributes to increased risk of HIV acquisition. This review focuses on HSV diagnostics, as well as what we have learned about the importance of frequent genital HSV shedding for (i) HSV transmission and (ii) genital tract inflammation, as well as (iii) the impact of HSV-2 infection on HIV acquisition and transmission. We conclude with discussion of future areas of research to push the field forward.

A wide variety of products are used by women in the genital area and, therefore, come into contact with the genital mucosa. The largest category of such products would be those used for cleanliness and odor control, such as soaps and body washes, douches, premoistened wipes and towelettes, dusting powder and deodorant sprays. A second large category of products are those intended to absorb fluids, such as products used for menstrual protection (tampons, pads and panty liners) and incontinence protection. Lubricants and moisturizers, and aesthetic products (hair removal products and dyes) are also fairly common. In addition, over the counter medications are now available for the treatment of fungal infections. This chapter briefly discusses the products women use on or around the genital area, the perceived or real benefits, and the potential health effects of these products. Copyright © 2011 S.

The study investigated the effectiveness of two online resources aimed at improving women's knowledge of the variation in normal female genital appearance and their attitudes towards their own genitals. The first consisted of a photographic array of normal female genitals and the second consisted of a video addressing digital airbrushing of women's genitals in media images. A sample of 136 female undergraduate students were randomly assigned to view the photographs, video, both the photographs and video, or neither. The video significantly increased women's perceptions of genital appearance diversity as well as awareness of digital airbrushing of genital images. Owing to relatively low levels of genital appearance concern, there was no effect of either resource on women's attitudes towards their own genitals; however, women who viewed the video indicated they would pass on their knowledge to help other women. Our results suggest that an educational video could be a useful tool. Copyright © 2015 Elsevier Ltd. All rights reserved.

Genital herpes is the most prevalent sexually transmitted infection in the USA. While sometimes mild in severity, it can be a distressing and painful chronic condition. Likewise, herpes labialis and herpes zoster can be both physically and psychologically painful. While there is no cure for these conditions, treatment to alleviate symptoms, suppress recurrences and reduce transmission has been drastically improved over the past 20 years with the use of guanine nucleoside antivirals, such as valacyclovir hydrochloride (Valtrex), GlaxoSmithKline) the highly bioavailable prodrug of acyclovir (Zovirax((R)), GlaxoSmithKline), and famciclovir (Famvir, Novartis), a highly bioavailable prodrug of penciclovir (Denavir, Novartis). Clinical trials involving approximately 10,000 patients (including patients from nongenital herpes studies, such as herpes zoster) have assessed the safety and efficacy of valacyclovir in the treatment of initial genital herpes outbreaks, episodic treatment of recurrent episodes and daily suppressive therapy. It was shown that valacyclovir has similar efficacy to acyclovir in the episodic and suppressive treatment of genital herpes. Valacyclovir is the only antiviral drug approved for a once-daily dose of suppressive therapy for genital herpes, as well as the only antiviral drug US FDA approved for a 3-day regimen of episodic treatment of recurrent genital herpes. In addition, valacyclovir is also indicated in the reduction of the sexual transmission of herpes simplex virus infection and for the treatment of herpes labialis. In herpes zoster, valacyclovir is more effective than acyclovir or placebo (and as equally effective as famciclovir) in shortening the length and severity of herpes zoster-associated pain and postherpetic neuralgia. Valacyclovir has an acceptable safety profile in patients with herpes simplex and herpes zoster. The less frequent dosing regimen makes it an attractive option in the treatment of genital herpes and other viral

The genitalia may be the site of non-infectious inflammatory lesions that are generally manifested as balanoposthitis and vulvovaginitis. In men, these forms constitute 50% of all balanoposthitis forms, and in women, vulvovaginitis frequency is even higher. They consist of genital locations of general skin diseases, such as psoriasis, lichen planus, lichen sclerosus, and other clinical entities with their own physiognomy, such as Zoon's balanitis-vulvitis. Diagnosis of genital non-infectious inflammatory lesions is usually made on clinical criteria. A biopsy is only necessary for the identification of clinical conditions that may simulate inflammatory form but are actually premalignant processes.

Chlamydia trachomatis is the most commonly reported agent of sexually transmitted bacterial infections worldwide. This pathogen frequently leads to persistent, long-term, subclinical infections, which in turn may cause severe pathology in susceptible hosts. This is in part due to the strategies that Chlamydia trachomatis uses to survive within epithelial cells and to evade the host immune response, such as subverting intracellular trafficking, interfering signaling pathways and preventing apoptosis. Innate immune receptors such as toll-like receptors expressed on epithelial and immune cells in the genital tract mediate the recognition of chlamydial molecular patterns. After bacterial recognition, a subset of pro-inflammatory cytokines and chemokines are continuously released by epithelial cells. The innate immune response is followed by the initiation of the adaptive response against Chlamydia trachomatis, which in turn may result in T helper 1-mediated protection or in T helper 2-mediated immunopathology. Understanding the molecular mechanisms developed by Chlamydia trachomatis to avoid killing and host immune response would be crucial for designing new therapeutic approaches and developing protective vaccines. In this review, we focus on chlamydial survival strategies and the elicited immune responses in male genital tract infections. © 2017 Society for Reproduction and Fertility.

The association of lichen sclerosus (LS) with genital squamous cell carcinoma is well recognized. However, the relationship between LS and verrucous carcinoma remains unclear. To evaluate the associations of genital and perianal verrucous carcinomas with LS. We conducted a retrospective study on patients with a genital or perianal verrucous carcinoma and reviewed their histopathology specimens and clinical notes. We also conducted a literature review. We identified a total of 13 patients (including 6 women and 7 men) with a genital or perianal verrucous carcinoma. All 5 women with vulval verrucous carcinoma had coexisting LS (5/5), and 1 man with penile verrucous carcinoma had coexisting LS (1/3). In contrast, no coexisting LS was found in all 5 cases of perianal verrucous carcinoma (0/5). Half of the cases of verrucous carcinoma with coexisting LS had recurrences (3/6), while no recurrences were found in those without coexisting LS (0/7). Our study and review of the literature demonstrate that vulval verrucous carcinoma is strongly associated with LS. In contrast, perianal verrucous carcinoma is not associated with LS. When genital verrucous carcinoma is diagnosed, it is important to consider LS as a potential concomitant diagnosis and offer appropriate treatments and close follow-up to detect recurrence of verrucous carcinoma.

Pyoderma gangrenosum is an ulcerative skin disorder showing characteristic non-infectious ulcers and affects the lower extremities in approximately 70% of cases. Pyoderma gangrenosum is commonly associated with systemic diseases such as inflammatory bowel disease, rheumatoid arthritis and hematological malignancies. Herein, we report two cases of Japanese patients diagnosed with genital pyoderma gangrenosum. Case 1 was a 74-year-old woman without associated systemic complications, whose skin lesion resembled a squamous cell carcinoma and was limited to the vulva. Case 2 is an 89-year-old man, who suffered from myelodysplastic syndrome and acute myeloid leukemia, and presented with penile and leg ulcers mimicking pressure sores. Both cases responded well to systemic steroids. We review 13 genital pyoderma gangrenosum cases (76.9% male; aged 30-89 years) from 1996 to 2012 in Japan, including 11 previously reported cases and the present study's two cases. Four of the 13 genital pyoderma gangrenosum cases had associated systemic diseases and their skin lesions spread to the extragenital areas. Eight of the remaining nine genitalia-localized pyoderma gangrenosum cases had no associated systemic diseases. In conclusion, genital pyoderma gangrenosum is rare and may be misdiagnosed. It should therefore be considered in cases of refractory genital ulcers. In addition, genitalia-localized pyoderma gangrenosum tends to be without systemic complications.

Background Human papillomavirus (HPV) causes two types of external genital lesions (EGLs) in men: genital warts (condyloma) and penile intraepithelial neoplasia (PeIN). Objective The purpose of this study was to describe genital HPV progression to a histopathologically confirmed HPV-related EGL. Design, Setting and Participants A prospective analysis nested within the HPV Infection in Men (HIM) Study was conducted among 3033 men. At each visit, visually distinct EGLs were biopsied, subjected to pathological evaluation, and categorized by pathological diagnoses. Genital swabs and biopsies were used to identify HPV types using the Linear Array genotyping method for swabs and INNO-LiPA for biopsies. Outcome Measurements EGL incidence was determined among 1788 HPV-positive men, and cumulative incidence rates at 6, 12, and 24 months were estimated. The proportion of HPV infections that progressed to EGL was also calculated, along with median time to EGL development. Results and Limitations Among 1788 HPV-positive men, 92 developed an incident EGL during follow-up (9 PeIN and 86 condyloma). During the first 12 months of follow-up, 16% of men with a genital HPV6 infection developed a HPV6-positive condyloma, and 22% of genital HPV11 infections progressed to an HPV11-positive condyloma. During the first 12-months of follow-up, 0.5% of men with a genital HPV16 infection developed an HPV16-positive PeIN. Although we expected PeIN to be a rare event, the sample size for PeIN (n=10) limited the types of analyses that could be performed. Conclusions Most EGLs develop following infection with HPV 6, 11, or 16, all of which could be prevented with the 4-valent HPV vaccine. Patient Summary In this study, we looked at genital HPV infections that can cause lesions in men. The HPV that we detected within the lesions could be prevented through a vaccine. PMID:26051441

Abstract Objective To summarize and determine the appropriate use for the new and old management tools for genital warts. Sources of information The following databases were searched: MEDLINE, PubMed, EMBASE, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, ACP Journal Club, and Trip. The bibliographies of retrieved papers were also reviewed. Clinical trials, qualitative review articles, consensus reports, and clinical practice guidelines were retrieved. Main message Symptomatic warts are prevalent in at least 1% of the population between the ages of 15 and 49, with estimates of up to 50% of the population being infected with human papillomavirus at some point in their lifetime. Imiquimod and podophyllotoxin are 2 new treatments for external genital warts that are less painful and can be applied by patients at home. In addition, the quadrivalent human papillomavirus vaccine has been shown to be efficacious in preventing genital warts and cervical cancer. There is still a role for the older treatment methods in certain situations, such as intravaginal, urethral, anal, or recalcitrant warts; or for pregnant patients. Conclusion The new treatments of external genital warts can reduce the pain of treatment and the number of office visits. Other treatment methods are still useful in certain situations. PMID:23851535

We reviewed the literature on protozoan infections in the male genital tract, with special reference to histopathological findings and their repercussions on different andrological functions. A literature search of the MEDLINE data base from 1966 to May 1995 was done and related articles were identified. The considered terms were parasitology and the male genital organs. Additional searches on infertility, semen and sexually transmitted diseases were performed. Protozoan infections of the male genital tract are rare and only a few species of parasites are involved. Trichomonas vaginalis, Trypanosoma species, Leishmania donovani, Entamoeba histolytica, Acanthamoeba species, Toxoplasma gondii and Plasmodium falciparum have been described in the male genital tract as producing testicular damage or secondary hypogonadism via hypothalamic-hypophyseal axis alterations. Topics of interest were the role of sexual transmission by some parasites, principally T. vaginalis, relationship with subfertility or infertility in the male subject, clinical significance in differential diagnosis with other inflammatory processes, and for some parasites the relationship with opportunistic behavior and immunodeficiency syndromes, including the acquired immunodeficiency syndrome.

The diversity, variability, and apparent rapid evolution of animal genitalia are a vivid focus of research in evolutionary biology, and studies exploring genitalia have dramatically increased over the past decade. These studies, however, exhibit a strong male bias, which has worsened since 2000, despite the fact that this bias has been explicitly pointed out in the past. Early critics argued that previous investigators too often considered only males and their genitalia, while overlooking female genitalia or physiology. Our analysis of the literature shows that overall this male bias has worsened with time. The degree of bias is not consistent between subdisciplines: studies of the lock-and-key hypothesis have been the most male focused, while studies of cryptic female choice usually consider both sexes. The degree of bias also differed across taxonomic groups, but did not associate with the ease of study of male and female genital characteristics. We argue that the persisting male bias in this field cannot solely be explained by anatomical sex differences influencing accessibility. Rather the bias reflects enduring assumptions about the dominant role of males in sex, and invariant female genitalia. New research highlights how rapidly female genital traits can evolve, and how complex coevolutionary dynamics between males and females can shape genital structures. We argue that understanding genital evolution is hampered by an outdated single-sex bias.

The traditional custom of ritual cutting and alteration of the genitalia of female infants, children, and adolescents, referred to as female genital mutilation or female genital cutting (FGC), persists primarily in Africa and among certain communities in the Middle East and Asia. Immigrants in the United States from areas in which FGC is common may have daughters who have undergone a ritual genital procedure or may request that such a procedure be performed by a physician. The American Academy of Pediatrics believes that pediatricians and pediatric surgical specialists should be aware that this practice has life-threatening health risks for children and women. The American Academy of Pediatrics opposes all types of female genital cutting that pose risks of physical or psychological harm, counsels its members not to perform such procedures, recommends that its members actively seek to dissuade families from carrying out harmful forms of FGC, and urges its members to provide patients and their parents with compassionate education about the harms of FGC while remaining sensitive to the cultural and religious reasons that motivate parents to seek this procedure for their daughters.

The paraoxonase type 1 (PON1) is an enzyme with antioxidant properties recently identified in the seminal plasma (SP) of several species, including the porcine. The aims of the present study were to (1) describe the immunohistochemical localisation of PON1 in the genital organs of fertile boars and (2) evaluate the relationship among PON1 activity and high-density lipoprotein cholesterol (HDL-C) concentration in fluids of the boar genital organs. Immunohistochemical analysis demonstrated that PON1 was present in testis (specifically in Leydig cells, blood vessels, spermatogonia and elongated spermatids), epididymis (specifically in the cytoplasm of the principal epithelial cells, luminal secretion and in the surrounding smooth muscle) and the lining epithelia of the accessory sexual glands (cytoplasmic location in the prostate and membranous in the seminal vesicle and bulbourethral glands). The Western blotting analysis confirmed the presence of PON1 in all boar genital organs, showing in all of them a band of 51 kDa and an extra band of 45 kDa only in seminal vesicles. PON1 showed higher activity levels in epididymal fluid than those in SP of the entire ejaculate or of specific ejaculate portions. A highly positive relationship between PON1 activity and HDL-C concentration was found in all genital fluids. In sum, all boar genital organs contributing to sperm-accompanying fluid/s were able to express PON1, whose activity in these genital fluids is highly dependent on the variable HDL-C concentration present. © 2017 Society for Reproduction and Fertility.

Sex determination is essential for the sexual reproduction to generate the next generation by the formation of functional male or female gametes. In mammals, primary sex determination is commenced by the presence or absence of the Y chromosome, which controls the fate of the gonadal primordium. The somatic precursor of gonads, the genital ridge is formed at the mid-gestation stage and gives rise to one of two organs, a testis or an ovary. The fate of the genital ridge, which is governed by the differentiation of somatic cells into Sertoli cells in the testes or granulosa cells in the ovaries, further determines the sex of an individual and their germ cells. Mutation studies in human patients with disorders of sex development and mouse models have revealed factors that are involved in mammalian sex determination. In most of mammals, a single genetic trigger, the Y-linked gene Sry (sex determination region on Y chromosome), regulates testicular differentiation. Despite identification of Sry in 1990, precise mechanisms underlying the sex determination of bipotential genital ridges are still largely unknown. Here, we review the recent progress that has provided new insights into the mechanisms underlying genital ridge formation as well as the regulation of Sry expression and its functions in male sex determination of mice.
Hypospadias is a developmental defect of urethral tube closure that has a complex etiology involving genetic and environmental factors, including anti-androgenic and estrogenic disrupting chemicals; however, little is known about the morphoregulatory consequences of androgen/estrogen balance during genital tubercle (GT) development. Computer models that predictively model sexual dimorphism of the GT may provide a useful resource to translate chemical-target bipartite networks and their developmental consequences across the human-relevant chemical universe. Here, we describe a multicellular agent-based model of genital tubercle (GT) development that simulates urethrogenesis from the sexually-indifferent urethral plate stage to urethral tube closure. The prototype model, constructed in CompuCell3D, recapitulates key aspects of GT morphogenesis controlled by SHH, FGF10, and androgen pathways through modulation of stochastic cell behaviors, including differential adhesion, motility, proliferation, and apoptosis. Proper urethral tube closure in the model was shown to depend quantitatively on SHH- and FGF10-induced effects on mesenchymal proliferation and epithelial apoptosis??both ultimately linked to androgen signaling. In the absence of androgen, GT development was feminized and with partial androgen deficiency, the model resolved with incomplete urethral tube closure, thereby providing an in silico platform for probabilistic prediction of hypospadias risk across c

Genital infantile hemangiomas are vascular anomalies that often require complex management and interdisciplinary care. Propranolol was first used to treat patients with infantile hemangiomas in 2008 and has since gained acceptance as first-line therapy. We review the presentation, course, management and outcomes of all cases of genital infantile hemangiomas managed by propranolol administration at a single institution from April 2010 to July 2014. During the study period 9 patients with genital infantile hemangiomas were referred to our hemangioma treatment clinic. Propranolol was initially administered under careful outpatient monitoring at a dose of 1 mg/kg daily in 8 patients. One patient, a 700 gm premature infant, was started on therapy in the inpatient setting at 0.5 mg/kg daily, given the history of prematurity. All patients underwent successful increase of dose to at least 2 mg/kg for the observation phase after tolerating the starting doses. One patient discontinued propranolol prematurely per parental request due to concern regarding peripheral vasoconstriction. Otherwise, no patient demonstrated significant hypotension, symptomatic bradycardia, hypoglycemia or other major side effect requiring treatment discontinuation. All patients who continued the treatment protocol had excellent response to therapy. Propranolol therapy for genital infantile hemangiomas was successfully initiated and the dosage increased in 9 young children without significant side effects and with marked improvement in all patients who continued on treatment. Propranolol is the only Food and Drug Administration approved therapy for treatment of patients with this vascular anomaly and should be considered first-line therapy for genital infantile hemangiomas.

To assess the role of genital tuberculosis as an etiological factor for ectopic pregnancy. A total of eighteen women of ectopic pregnancy with concomitant female genital tuberculosis and a total of one hundred thirty six patients of ectopic pregnancy over a period of three years were enrolled. Mean age of patients with ectopic pregnancy and concomitant female genital tuberculosis was twenty-six and mean parity was 0.7. Most of these patients were in poor socio-economic group. Diagnosis of female genital tuberculosis was made by presence of granuloma in histopathological examination of endometrial aspirate or tubal specimen, positive acid fast bacilli in microscopy or culture, positive polymerase chain reaction in endometrial tissue and positive findings of genital tuberculosis during laparoscopy or laparotomy. Genital tuberculosis was responsible for 13.2% of all cases of ectopic pregnancy in the present study. Genital tuberculosis appears to be an important cause of ectopic pregnancy in India.

Genital condyloma-like lesions were observed on male and female cynomolgus macaque monkeys (Macaca fascicularis) originating from the island of Mauritius. Cytobrush and/or biopsy samples were obtained from lesions of 57 affected macaques. Primary histologic features included eosinophilic, neutrophilic, and lymphoplasmacytic penile and vulvar inflammation, epidermal hyperplasia with acanthosis, and increased collagenous stroma. Polymerase chain reaction-based assays to amplify viral DNA revealed the presence of macaque lymphocryptovirus (LCV) DNA but not papillomavirus or poxvirus DNA. Subsequent DNA analyses of 3 genomic regions of LCV identified isolates associated with lesions in 19/25 (76%) biopsies and 19/57 (33%) cytology samples. Variable immunolabeling for proteins related to the human LCV Epstein Barr Virus was observed within intralesional plasma cells, stromal cells, and epithelial cells. Further work is needed to characterize the epidemiologic features of these lesions and their association with LCV infection in Mauritian-origin macaques.

Background Androgen insensitivity syndrome (AIS) comprises a range of phenotypes from male infertility to complete feminization. Most individuals with AIS carry germline mutations of the androgen receptor (AR) that interfere with or ablate its function. As genital fibroblasts retain expression of the AR in vitro, we used genital skin fibroblasts from normal males and 46,XY females with complete AIS due to known AR mutations to gain insights into the role of the AR in human genital differentiation. Results Using DNA microarrays representing 32,968 different genes, we identified 404 transcripts with significant differences in transcription levels between genital skin fibroblasts cultured from normal and AIS-affected individuals. Gene-cluster analyses uncovered coordinated expression of genes involved in key processes of morphogenesis. On the basis of animal studies and human genetic syndromes, several of these genes are known to have specific roles in genital differentiation. Remarkably, genital fibroblasts from both normal and AIS-affected individuals showed no transcriptional response to dihydrotestosterone treatment despite expression of the AR. Conclusions The results suggest that in addition to differences in the anatomic origin of the cells, androgen signaling during prenatal development contributes to setting long-lasting, androgen-independent transcriptional programs in genital fibroblasts. Our findings have broad implications in understanding the establishment and the stability of sexual dimorphism in human genital development. PMID:12801411

Although the pathologic consequences of C. trachomatis genital infection are well-established, the mechanism(s)that result in chlamydia-induced tissue damage are not fully understood. We reviewed in vitro, animal, and human data related to the pathogenesis of chlamydial disease to better understand how reproductive sequelae result from C. trachomatis infection. Abundant in vitro data suggest that the inflammatory response to chlamydiae is initiated and sustained by actively infected nonimmune host epithelial cells. The mouse model indicates a critical role for chlamydia activation of the innate immune receptor, Toll-like receptor 2, and subsequent inflammatory cell influx and activation, which contributes to the development of chronic genital tract tissue damage. Data from recent vaccine studies in the murine model and from human immunoepidemiologic studies support a role for chlamydia-specific CD4 Th1-interferon-g-producing cells in protection from infection and disease. However, limited evidence obtained using animal models of repeated infection indicates that, although the adaptive T cell response is a key mechanism involved in controlling or eliminating infection, it may have a double-edged nature and contribute to tissue damage. Important immunologic questions include whether anamnestic CD4 T cell responses drive disease rather than protect against disease and the role of specific immune cells and inflammatory mediators in the induction of tissue damage with primary and repeated infections. Continued study of the complex molecular and cellular interactions between chlamydiae and their host and large-scale prospective immunoepidemiologic and immunopathologic studies are needed to address gaps in our understanding of pathogenesis that thwart development of optimally effective control programs, including vaccine development.

Little information is available about idiosyncratic historical details provided by sexually abused girls, yet this information can help medical professionals diagnose sexual abuse. Our goals were to describe types and frequencies of urogenital symptoms/signs reported by girls who disclosed direct genital contact and to explore factors associated with this reporting. We reviewed 161 medical charts of 3- to 18-year-old girls who disclosed sexual abuse by direct genital contact for urogenital symptoms/signs, type of genital contact (oral, object, digital, or genital), time interval between last perpetrator contact and physical examination, age and sexual maturity at the time of last perpetrator contact, genital findings, and other medical diagnoses. Regression analyses were performed to determine factors that were most predictive of symptom/sign reporting. Many of the girls reported multiple types of genital contact; 33% reported oral/object-genital contact, 72% reported digital-genital contact, and 55% reported genital-genital contact. Sixty percent of the girls reported experiencing >or=1 symptom/sign; 53% of the total sample had genital pain, 37% had dysuria, and 11% had genital bleeding. Symptoms/signs were highly associated with genital-genital contact: 48% of the girls reporting genital-genital contact had dysuria compared with 25% of girls not reporting genital-genital contact, 72% had genital pain/soreness compared with 32% not reporting genital-genital contact, and 16% had bleeding compared with 4% of those not reporting genital-genital contact. Using regression analysis, the strongest factor predictive of symptom reporting by the girls was genital-genital contact. Sexually abused girls who experienced direct genital contact frequently reported symptoms related to the abusive episode. These symptoms were reported most frequently with genital-to-genital contact. This information sheds some light on the mechanism of injury leading to symptom reporting and can

Clinical and subclinical genital herpes simplex virus type 2 (HSV-2) reactivations have been associated with increases in human immunodeficiency virus (HIV)-1 genital shedding. Whether HSV-2 shedding contributes to the selection of specific genital HIV-1 variants remains unknown. We evaluated the genetic diversity of genital and blood HIV-1 RNA and DNA in 14 HIV-1/HSV-2-co-infected women, including seven with HSV-2 genital reactivation, and seven without as controls. HIV-1 DNA and HIV-1 RNA env V1-V3 sequences in paired blood and genital samples were compared. The HSV-2 selection pressure on HIV was estimated according to the number of synonymous substitutions (dS), the number of non-synonymous substitutions (dN) and the dS/dN ratio within HIV quasi-species. HIV-1 RNA levels in cervicovaginal secretions were higher in women with HSV-2 replication than in controls (p0.02). Plasma HIV-1 RNA and genital HIV-1 RNA and DNA were genetically compartmentalized. No differences in dS, dN and the dS/dN ratio were observed between the study groups for either genital HIV-1 RNA or plasma HIV-1 RNA. In contrast, dS and dN in genital HIV-1 DNA were significantly higher in patients with HSV-2 genital reactivation (p <0.01 and p <0.05, respectively). The mean of the dS/dN ratio in genital HIV-1 DNA was slightly higher in patients with HSV-2 genital replication, indicating a trend for purifying selection (p 0.056). HSV-2 increased the genetic diversity of genital HIV-1 DNA. These observations confirm molecular interactions between HSV-2 and HIV-1 at the genital tract level.

Nowadays, women with genital cancers live longer due to early diagnosis and better treatment schemes. Only few studies assessed bone mass in patients with genital cancer Osteoporosis is a condition characterized by progressive loss of bone mass, weakening of the spatial structure of the bone, and increased susceptibility to fractures. Osteopenia is a condition of reduced, but not yet reaching the pathological values, bone density in relation to norms for age and sex. Metastases are the primary cause of death in cancer patients. It is estimated that approximately half of people dying due to cancer have bone metastases. Osteoporosis in neoplastic disease may occur due to bone metastases or therapy-related adverse effects, i.e. reduced bone mineral density (BMD). Bone microenvironment provides a good medium for the growth of cancer cells. BMD of the femur and spine should be measured by DXA. Computed tomography (CT) and magnetic resonance imaging (MRI) are the techniques used to detect bone metastases. Lifestyle is the key to improving the quality of life and maximize any pharmacological treatment in cancer patients. It is proposed that treatment of cancer without bone metastases does not require therapy increasing bone mass. Further studies in women treated for gynecological malignancies undergoing oophorectomy and adjuvant treatment are needed to elucidate the mechanisms associated with bone loss.

A 23-year-old woman presented with large exophytic genital wart arising from perineum, vulva, introitus of the vagina, and inner aspect of thighs. Patient developed severe itching and formication (insect-crawling sensation) in the lesions for past 1 week, though careful examination did not reveal any insects. Considering that the disease was causing psychological stress and physical symptoms, radiofrequency excision was planned. However, during the procedure, several maggots appeared from the crypts. The procedure was abandoned and maggots were removed manually. Subsequently external giant warts were removed using radiofrequency device. There was no recurrence of excised warts during 3 month follow-up. To our knowledge, this is the second reported case of maggots in genital warts. PMID:21976905

Dermatoscopy as a non-invasive technique has become an integrative part in the evaluation of pigmented and non-pigmented skin lesions, particularly for the early detections of melanoma. Although dermatoscopy improves diagnosis of pigmented and nonpigmented lesions of the skin, it is unknown if dermatoscopy improves the diagnostic accuracy of pigmented mucosal lesions. The "entodermatoscopy" is used for the dermatoscopy of skin infections and infestations and revised as entomodermatoscopy, as it connects the research fields of dermatology and entomology, with its roots being found in these two words. In genital dermatology along with the clinical examination, dermatoscopy is also used for the diagnosis and treatment follow-up of pediculosis pubis, genital warts, molluscum contagiosum, and scabies.

In this paper we summarise the parasitological, clinical and epidemiological characteristics of female genital schistosomiasis (FGS), a frequent manifestation of the infection with Schistosoma haematobium. Means to diagnose and treat lesions in the lower and upper genital tract are discussed. Based on clinical findings and available pathophysiological as well as immunological data it is conceivable that FGS of the cervix and vagina not only facilitates the infection with agents of sexually transmitted diseases, but presumably also alters the natural history of such infections. Two infectious agents are of particular concern: the Human Immunodeficiency Virus and the oncogenic Human Papilloma Viruses. Possible interactions and their consequences are discussed and research areas which should be addressed are outlined.
Lichen planus (LP) is an inflammatory autoimmune disease that affects both glabrous and mucosal skin. Although pathophysiology has not yet been fully defined, LP is a T-cell mediated disorder that demonstrates an increased Th1 cytokine expression as well as T-cell reactivity against basement membrane zone components. In males, genital LP often takes its more classic form as pink, shiny, flat-topped papules on the glans and coronal sulcus. In women, erosive disease is most common and often leads to significant scarring and sexual dysfunction. Therapeutic management is challenging, and control rather than cure is the goal. Topical corticosteroids remain first-line therapy, but some women will require systemic immunosuppressants to achieve remission. Surgery is less common for women with significant scarring who wish to resume sexual activity. Further research is needed on pathogenesis, and randomized controlled trials are necessary to better define best treatments for this chronic disease. ©2015 Frontline Medical Communications.

The ducts associated with sperm transport from the testicular lobules to the Wolffian ducts in Ambystoma maculatum were examined with transmission electron microscopy. Based on the ultrastructure and historical precedence, new terminology for this network of ducts is proposed that better represents primary hypotheses of homology. Furthermore, the terminology proposed better characterizes the distinct regions of the sperm transport ducts in salamanders based on anatomy and should, therefore, lead to more accurate comparisons in the future. While developing the above ontology, we also tested the hypothesis that nephrons from the genital kidney are modified from those of the pelvic kidney due to the fact that the former nephrons function in sperm transport. Our ultrastructural analysis of the genital kidney supports this hypothesis, as the basal plasma membrane of distinct functional regions of the nephron (proximal convoluted tubule, distal convoluted tubule, and collecting tubule) appear less folded (indicating decreased surface area and reduced reabsorption efficiency) and the proximal convoluted tubule possesses ciliated epithelial cells along its entire length. Furthermore, visible luminal filtrate is absent from the nephrons of the genital kidney throughout their entire length. Thus, it appears that the nephrons of the genital kidney have reduced reabsorptive capacity and ciliated cells of the proximal convoluted tubule may increase the movement of immature sperm through the sperm transport ducts or aid in the mixing of seminal fluids within the ducts.
Estradiol is a steroid hormone that regulates the structure and function of the female reproductive system. In addition to its genomic effects, which are mediated by activated nuclear receptors, estradiol elicits a variety of rapid signaling events independently of transcriptional or genomic regulation. These nongenomic actions influence the milieu of the genital tract, which changes the ability of pathogens to infect the genital tract. This review discusses our current knowledge regarding the mechanisms and relevance of nongenomic estradiol signaling in the genital tract that could change the ability of pathogens to invade epithelial cells. PubMed was searched through January 1980 for papers related to estradiol actions in the ovary, fallopian tube, uterus and cervix. The mechanisms conveying these rapid effects consist of a multitude of signaling molecules and include cross-talk with slower transcriptional actions. The nongenomic actions of estradiol that influence the infectious abilities of pathogens occur either directly on the genital tract cells or indirectly by modulating the local and systemic immune systems. Additional in-depth characterization of the response is required before the normal and pathological reproductive functions of the nongenomic estradiol pathway can be targeted for pharmacological intervention.

A 54-year-old woman presented to a community-based psychiatric clinic with unique problem of persistent genital arousal disorder. All relevant investigations were normal. Treatment with psychotropic medication and psychotherapy did not help. The patient though reported improvement in mood. The patient has been followed up since 2011 and visits the clinic every 3 months without much improvement in the disorder. Hence, this case has become a clinical challenge in terms of treatment.

This chapter discusses the all too common problem of sex-related pain in women. Pain is a complex perceptive experience, involving biologic as well as psychologic and relational meanings. They become increasingly important with the chronicity of pain. Neurologists are quite aware of the painful aspect of many neurologic disorders, but lifelong and acquired genital and sexual pain is still neglected in a consistent percentage of women. One reason is the view - still held by many - that psychologic factors play the most important role in sex-related pain complaints. The consequences of diagnostic delay can be dramatic. Persisting tissue inflammation induces pain to change from acute and "nociceptive," which indicates a "friendly signal," alerting one to ongoing tissue damage, to chronic and "neuropathic," a disease per se. Whilst the primary disease is progressing and neuroinflammation becomes a prominent feature, affected women have to bear years of pain and distress, huge quantifiable and non-quantifiable costs, and a progressive deterioration of personal and relational health and happiness. The scenario is even more dramatic when pain complicates an already disabling disease. The main aspects considered in this chapter include neuroinflammation as a key feature of pain; genital and sexual pain as part of neurologic diseases; and genital and sexual pain syndrome (dyspareunia and vaginismus) as primary problems, and their pelvic comorbidities (bladder pain syndrome, endometriosis, irritable bowel syndrome, provoked vestibulodynia/vulvodynia). Finally, we discuss iatrogenic pain, i.e., genital and sexual pain caused by ill-conceived medical, surgical, pharmacologic or radiologic therapeutic interventions.

"Anatomy is destiny": Sigmund Freud viewed human anatomy as a necessary, although not a sufficient, condition for understanding the complexity of human sexual function with a solid biologic basis. The aim of the chapter is to describe women's genital anatomy and physiology, focusing on women's sexual function with a clinically oriented vision. Key points include: embryology, stressing that the "female" is the anatomic "default" program, differentiated into "male" only in the presence of androgens at physiologic levels for the gestational age; sex determination and sex differentiation, describing the interplay between anatomic and endocrine factors; the "clitoral-urethral-vaginal" complex, the most recent anatomy reading of the corpora cavernosa pattern in women; the controversial G spot; the role of the pelvic floor muscles in modulating vaginal receptivity and intercourse feelings, with hyperactivity leading to introital dyspareunia and contributing to provoked vestibulodynia and recurrent postcoital cystitis, whilst lesions during delivery reduce vaginal sensations, genital arousability, and orgasm; innervation, vessels, bones, ligaments; and the physiology of women's sexual response. Attention to physiologic aging focuses on "low-grade inflammation," genital and systemic, with its impact on women sexual function, especially after the menopause, if the woman does not or cannot use hormone replacement therapy. © 2015 Elsevier B.V.

Female genital mutilation is still practiced in 28 African countries despite international calls for its abolishment. A 1991 survey of 1365 14-year-old girls undertaken by a nongovernmental organization in Kenya revealed that 90% had suffered mutilation ranging from the least mutilating form, "sunna" to excision to infibulation. Most of the procedures had taken place when the girls were aged 10-14 years as part of a ritual where the same unsterile knife was used on several girls. Whereas 65% of respondents stated that they approved of female genital mutilation, a little more than a third would abolish the practice. In Sudan, a 1989-90 Demographic and Health Survey of 5860 ever married women aged 15-49 included a number of questions related to female genital mutilation. 89% of respondents were mutilated, and 82% of these had suffered infibulation. This prevalence rate showed a decrease from the 96% level recorded in 1977-78. Among younger women, the incidence of sunna is increasing. Most of these procedures were performed by medical workers such as trained midwives or traditional birth attendants. 79% of the respondents favored continuation of the procedure, but women with a secondary-level education and urban women showed strong opposition. Most women cite tradition as the reason for their approval, and almost half of the women who disapprove cite medical complications. This survey provided the necessary data to implement a policy of eradication of this harmful practice through increasing women's education and provoking open discussion about the procedure.

The female bony pelvis has to fulfil opposing functions: it has to be sufficiently closed to support the pelvic viscera in the upright position, while remaining sufficiently open to allow vaginal delivery. We aim to give an evolutionary perspective and the possible evolution of the bony pelvis from Lucy to the modern female with the implications in terms of genital prolapse. Thirteen pelvimetric measurements were performed on 178 bony pelves: 1 fossil pelvis from Australopithecus Lucy, 128 female Caucasian modern adult pelves and 49 female Catarrhine pelves (29 gorillas and 20 chimpanzees). Lucy's pelvis shape was the most transversely oval, short and broad, termed platypelloid. Modern female pelves were transversely oval only at the inlet. A protruding ischial spine, fairly small ischial tuberosities and a sacral concavity made Lucy closer to Homo sapiens and less like the great apes. In the last group, pelvic planes were anteroposteriorly oval, except in the gorilla, where the outlet was round or slightly transversely oval. The subpubic angle was narrowest in Lucy, whereas it was greater than 90° in the great apes. The female pelvis is involved in both visceral support and parturition and represents a compromise. The narrower pelvis of Australopithecus Lucy provided protection against genital prolapse, but resulted in complex obstetrical mechanics. From an evolutionary perspective, the pelvis of Homo sapiens became modified to make parturition easier, but increased the risk of genital prolapse: the ilia became wide open laterally and the sacrum broadened with a shorter distance between the sacroiliac and coxofemoral joints.

Background. It is not known if fluctuations in genital tract antiretroviral drug concentrations correlate with genital virus shedding in human immunodeficiency virus (HIV)–infected women on antiretroviral therapy (ART). Methods. Among 20 HIV-infected women on ART (tenofovir [TFV], emtricitabine [FTC], and ritonavir-boosted atazanavir [ATV]) with suppressed plasma virus loads, blood and cervicovaginal samples collected twice weekly for 3 weeks were tested for antiretroviral concentrations, HIV-1 RNA, and proviral DNA. Results. Cervicovaginal:plasma antiretroviral concentration ratios were highest for FTC (11.9, 95% confidence interval [CI], 8.66–16.3), then TFV (3.52, 95% CI, 2.27–5.48), and ATV (2.39, 95% CI, 1.69–3.38). Within- and between-person variations in plasma and genital antiretroviral concentrations were observed. Low amounts of genital HIV-1 RNA (<50 copies/mL) were detected in 45% of women at 16% of visits. Genital HIV-1 DNA was detected in 70% of women at 35% of visits. Genital virus detection was associated with higher concentrations of mucosal leukocytes but not with genital antiretroviral concentrations, menstrual cycle phase, bacterial vaginosis, genital bleeding, or plasma virus detection. Conclusions. Standard doses of ART achieved higher genital than plasma concentrations across the menstrual cycle. Therapeutic ART suppresses genital virus shedding throughout the menstrual cycle, even in the presence of factors reported to increase virus shedding. PMID:24643223

Genital infection by Schistosoma mansoni is usually misdiagnosed in individuals who reside in, or travel to endemic areas. We describe two cases of genital tumor associated with S. mansoni infection manifested by methrorragy. Surgical specimens revealed leiomyomas in both cases associated with S. mansoni. In one of them, granulomas were found in the ovary and in the other they were found in the uterine tube. Although none presented intestinal/hepatic disease, fecal egg excretion was detected in one. Both had elevated pretreatment antibody reactivity to S. mansoni antigen, but follow-up showed different outcomes. Schistosomiasis should be considered as a diagnosis in individuals with methrorragy residing in or having traveled to endemic areas. Since diagnosis follows genital amputation, and cure control is troublesome, improvement of diagnostic tools and follow-up markers are important priorities to decrease schistosomiasis morbidity.
To present an overview of the prevalence of genital herpes in older women and to present case studies of older women diagnosed with genital herpes in a geriatric practice in the southeastern United States. Review of current scientific literature and treatment/practice guidelines. Specific descriptive cases are reviewed to illustrate the clinical problem. Genital herpes is an important differential diagnosis to include when assessing and treating older women for recurrent genital symptoms. Given the large numbers of older individuals potentially infected with genital herpes, the nurse practitioner (NP) is well positioned to accurately diagnose and initiate treatment that can improve quality of life. The NP's skill in education and counseling is essential to the ongoing management of genital herpes infections.

Genital elephantiasis is a disease that is characterized by massive enlargement of the genitalia. Early aetiological diagnosis is of paramount importance so that development of genital elephantiasis can be prevented; otherwise it is not completely reversible with medical therapy and often requires surgical intervention. Chronic mental distress and disability can result as it interferes with daily/routine activities of the affected individual. Over time, the infectious causes of genital elephantiasis have evolved, from syphilis in the pre-penicillin era to donovanosis, lymphogranuloma venereum and recently filariasis, tuberculosis, leishmaniasis, HIV and chromoblastomycosis. With a declining prevalence globally, donovanosis is at risk of being forgotten as a cause of genital swelling; however, it is known to persist for years without treatment and can lead to complications such as lymphoedema and genital mutilation. We herein present a case of genital elephantiasis that was eventually diagnosed as being due to donovanosis.

Defining the mechanisms of immunity conferred by the combination of antibody and CD4+ T cells is fundamental to designing an efficacious chlamydial vaccine. Using the Chlamydia muridarum genital infection model of mice, which replicates many features of human C. trachomatis infection and avoids the characteristic low virulence of C. trachomatis in the mouse, we previously demonstrated a significant role for antibody in immunity to chlamydial infection. We found that antibody alone was not protective. Instead, protection appeared to be conferred through an undefined antibody-cell interaction. Using gene knockout mice and in vivo cellular depletion methods, our data suggest that antibody-mediated protection is dependent on the activation of an effector cell population in genital tract tissues by CD4+ T cells. Furthermore, the CD4+ T cell-secreted cytokine gamma interferon (IFN-γ) was found to be a key component of the protective antibody response. The protective function of IFN-γ was not related to the immunoglobulin class or to the magnitude of the Chlamydia-specific antibody response or to recruitment of an effector cell population to genital tract tissue. Rather, IFN-γ appears to be necessary for activation of the effector cell population that functions in antibody-mediated chlamydial immunity. Our results confirm the central role of antibody in immunity to chlamydia reinfection and demonstrate a key function for IFN-γ in antibody-mediated protection. PMID:27600502

Mammalian external genitals show sexual dimorphism [1, 2] and can change size and shape upon sexual arousal. Genitals feature prominently in the oldest pieces of figural art  and phallic depictions of penises informed psychoanalytic thought about sexuality [4, 5]. Despite this longstanding interest, the neural representations of genitals are still poorly understood . In somatosensory cortex specifically, many studies did not detect any cortical representation of genitals [7-9]. Studies in humans debate whether genitals are represented displaced below the foot of the cortical body map [10-12] or whether they are represented somatotopically [13-15]. We wondered what a high-resolution mapping of genital representations might tell us about the sexual differentiation of the mammalian brain. We identified genital responses in rat somatosensory cortex in a region previously assigned as arm/leg cortex. Genital responses were more common in males than in females. Despite such response dimorphism, we observed a stunning anatomical monomorphism of cortical penis and clitoris input maps revealed by cytochrome-oxidase-staining of cortical layer 4. Genital representations were somatotopic and bilaterally symmetric, and their relative size increased markedly during puberty. Size, shape, and erect posture give the cortical penis representation a phallic appearance pointing to a role in sexually aroused states. Cortical genital neurons showed unusual multi-body-part responses and sexually dimorphic receptive fields. Specifically, genital neurons were co-activated by distant body regions, which are touched during mounting in the respective sex. Genital maps indicate a deep homology of penis and clitoris representations in line with a fundamentally bi-sexual layout  of the vertebrate brain.

Rapid and divergent evolution of male genital morphology is a conspicuous and general pattern across internally fertilizing animals. Rapid genital evolution is thought to be the result of sexual selection, and the role of natural selection in genital evolution remains controversial. However, natural and sexual selection are believed to act antagonistically on male genital form. We conducted an experimental evolution study to investigate the combined effects of natural and sexual selection on the genital-arch lobes of male Drosophila simulans. Replicate populations were forced to evolve under lifetime monogamy (relaxed sexual selection) or lifetime polyandry (elevated sexual selection) and two temperature regimes, 25°C (relaxed natural selection) or 27°C (elevated natural selection) in a fully factorial design. We found that natural and sexual selection plus their interaction caused genital evolution. Natural selection caused some aspects of genital form to evolve away from their sexually selected shape, whereas natural and sexual selection operated in the same direction for other shape components. Additionally, sexual and natural selection tended to favour larger genitals. Thus we find that the underlying selection driving genital evolution is complex, does not only involve sexual selection, and that natural selection and sexual selection do not always act antagonistically.

Human papillomavirus (HPV) is the most common newly diagnosed sexually transmitted infection in the United States. Although the majority of sexually active adults will be infected with HPV at least once in their lives, it is sexually active women less than 25 years of age who consistently have the highest rates of infection. Besides youth and gender, common risk factors for HPV infection and clinical sequelae of infection include high number of sexual partners and coinfection with Chlamydia trachomatis or herpes simplex virus. Most HPV infections are cleared by the immune system and do not result in clinical complications. Clinical sequelae in cases of low-risk HPV infection consist of genital warts, and clinical manifestations of high-risk HPV infection include abnormal Pap test results, low-grade squamous intraepithelial lesions (LSIL), high-grade squamous intraepithelial lesions (HSIL), and cervical cancer. LSIL, HSIL, and cervical cancer carry significant morbidity and/or mortality; genital warts and abnormal Pap test results are often significant sources of psychosocial distress. Currently, there are neither effective means of preventing HPV transmission nor cures for clinical manifestations: infection can only be prevented via complete sexual abstinence, while treatment for clinical sequelae such as genital warts and cytologic abnormalities consists of removing the problematic cells and watching for recurrence; this method consumes significant health care resources and is costly. New prophylactic HPV vaccines promise to dramatically reduce the incidence of HPV infection, genital warts, and cytologic abnormalities.

Control of genital infections remains challenging in most regions. Despite advocacy by the World Health Organization for syndromic case management, there are limited data on the syndromic approach, especially in HIV care settings. This study compared the syndromic approach with laboratory diagnosis among women in HIV care in Kenya. A mobile team visited 39 large HIV care programmes in Kenya and enrolled participants using population-proportionate sampling. Participants provided behavioural and clinical data with genital and blood specimens for lab testing. Among 1063 women, 68.4% had been on antiretroviral therapy >1 year; 58.9% were using cotrimoxazole prophylaxis; 51 % had CD4+T-lymphocytes < 350 cells/µL. Most women (63.1%) reported at least one genital symptom. Clinical signs were found in 63% of women; and 30.8% had an aetiological diagnosis. Bacterial vaginosis (17.4%), vaginal candidiasis (10.6%) and trichomoniasis (10.5%) were the most common diagnoses. Using laboratory diagnoses as gold standard, sensitivity and positive predictive value of the syndromic diagnosis for vaginal discharge were 47.6% and 52.7%, respectively, indicating a substantial amount of overtreatment. A systematic physical examination increased by 9.3% the positive predictive value for genital ulcer disease. Women attending HIV care programmes in Kenya have high rates of vaginal infections. Syndromic diagnosis was a poor predictor of those infections. © The Author(s) 2015.

We developed and morphologically characterized a human genital mucosa explant model (endocervix and ectocervix/vagina) to mimic genital herpes infections caused by herpes simplex virus types 1 (HSV-1) and 2 (HSV-2). Subsequent analysis of HSV entry receptor expression throughout the menstrual cycle in genital tissues was performed, and the evolution of HSV-1/-2 mucosal spread over time was assessed. Nectin-1 and -2 were expressed in all tissues during the entire menstrual cycle. Herpesvirus entry mediator expression was limited mainly to some connective tissue cells. Both HSV-1 and HSV-2 exhibited a plaque-wise mucosal spread across the basement membrane and induced prominent epithelial syncytia.

Female genital mutilation (FGM) is the partial or total removal of the female external genitalia or other deliberate injury to the female genital organs, either for cultural or non-therapeutic reasons. This barbaric act is accompanied by a variety of complications ranging from hemorrhage, fracture, infective complications, gynetresia, with its attendant sexual and obstetric difficulties, and death. A 23-year-old girl, with urinary and genital tract obstruction following female genital mutilation(infibulation) is presented. She was managed by elective defibulation, with a satisfactory outcome. Robust health education strategies are needed for the eradication of FGM.

The genital mucosa is a barrier that is constantly exposed to a variety of pathogens, allergens, and external stimuli. Although both allergen exposure and parasite infections frequently occur in the genital area, the mechanism by which immune responses—particularly type 2 immunity—are induced has rarely been studied in the genital mucosa. Here, we demonstrate the induction of T helper type 2 (Th2) immunity in the genital mucosa in response to a model allergen, the protease papain. Intravaginal papain immunization induced type 2 immunity in a manner that was dependent on protease activity and the estrous phase of the mice. In addition, IL-33 was released from the vaginal epithelia after intravaginal papain immunization, leading to the activation of type 2 innate lymphoid cells (ILC2s). Moreover, the IL-33–MyD88 (myeloid differentiation primary response gene 88) signaling pathway was critical for the induction of type 2 immunity. We also found that Th2 differentiation in response to intravaginal papain treatment requires a specific dendritic cell (DC) subset that is controlled by interferon regulatory factor 4 (IRF4). These findings suggest that type 2 immunity is induced by a unique mechanism in the genital tract, which is an important, but often overlooked, barrier surface. PMID:28137851

Genital melanoma is a rare pathology. We present the experience of two comprehensive cancer centers in Lyon (France) in the management of genital melanoma in order to identify prognostic factors and optimal treatments. Between April 1992 and Mars 2014, 16 patients with a primary genital melanoma were referred to our department. Nine patients presented a vaginal melanoma, six vulvar melanomas and only one cervical melanoma. The median dimension of the lesion was 33.7 mm (5-100 mm). The AJCC stage ranged from IB to IIIC. 12 cases were the classic dark-blue flat melanoma and the other 4 cases were an atypical amelanotic tumor. Wide local surgery was performed in nine patients. A radical surgery was performed in six patients. In the large cervical melanoma, radiotherapy was performed as first-line treatment. In all the patients regional lymph node staging was performed. Adjuvant treatment was realized in nine patients. Two patients are alive without recurrence. Only one patient was lost to the first follow-up. The other 13 patients experienced a rapid recurrence. The median disease-free survival and the median overall survival were 11.8 months (2-49 m) and of 30.4 m (11-144 m), respectively. The disease-free survival and overall survival could be linked to a clinical presentation (Breslow thickness and morphology of lesion) associated to the early diagnosis. In our small series, the most important prognosis factor remains the tumor thickness. These rare lesions should be treated in experienced centers in order to improve their prognostic.

Human papillomavirus (HPV) infection, a primary cause of genital cancer, is also related to the increasing incidence of oropharyngeal cancer among young men. Relatively little is known about the concurrence of oral and genital infection among healthy individuals. Oral and genital swab exfoliated cells were collected simultaneously from 2566 men in rural China. Using general primer-mediated (SPF1/GP6+) PCR and sequencing, HPV testing results were obtained from 2228 men with both valid oral and genital specimens (β-globin-positive). The prevalence of HPV infection was 6.7% in the oral cavity and 16.9% for the external genitalia. Among 43 men (1.9%, 43/2228) with oral-genital coinfection, 60.5% (26/43) harbored an identical HPV type at both sites. The risk of oral HPV infection was higher among men with genital infection than among uninfected men (11.4% vs. 5.7%, Adjusted OR = 2.3, 95% CI: 1.6–3.4). In addition, having multiple lifetime sexual partners was a significant risk for oral-genital HPV coinfection (Adjusted OR = 2.6, 95% CI: 1.0–7.0; 2 partners vs. 1 partner). These findings provide a basis for further understanding the natural history and transmission dynamics of oral HPV infection. PMID:26503510

More than 130 million women worldwide have undergone female genital cutting (FGC). FGC occurs in parts of Africa and Asia, in societies with various cultures and religions. Reasons for the continuing practice of FGC include rite of passage, preserving chastity, ensuring marriageability, religion, hygiene, improving fertility, and enhancing sexual pleasure for men. The World Health Organization has classified FGC into 4 types depending on the extent of tissue removed. Immediate complications include hemorrhage, infection, sepsis, and death. Long-term complications include pain, scarring, urinary issues, and poor obstetric and neonatal outcomes. Efforts are being made nationally and internationally to eradicate this practice.

Female genital mutilation, traditionally known as female circumcision, is a surgically unnecessary modification of the female genitalia, practiced in nations in Africa, the Arab Peninsula, among some communities in Asia, and among immigrants and refugees from these areas who have settled in other areas. The practice is known across socio-economic classes and among many different ethnic and cultural groups, including Christians, Muslims, Jews, and followers of indigenous African religions. As people from these areas immigrate to North America, health care professionals need to understand the important aspects of this growing problem, including management of complications, cultural attitudes, and sensitivities.

Female genital mutilation (FGM) is an unusual condition for our country. However, an increase in FGM in future days can be predicted with the increasing numbers of exchange students coming from African countries, migration of refugees and socioeconomic relations with the African countries. We want to share our experience of two FGM victims admitted to our clinic with the request of reconstructive vulvar surgery before their marriage. Both women had WHO Type III FGM. Physical examination findings and surgical reconstruction techniques were presented. PMID:27274899

This paper provides some basic information about female genital mutilation (FGM) as a social problem and as a health problem. It includes selected actions taken over the last 45 years by the United Nations regarding FGM. The focus here is on the ethics of individuals and institutions, such as the World Health Organization, attempting to intervene in traditional cultural practices like FGM. This discussion raises some questions about ethical universals and ethical relativism with regards to FGM and the attempts to change or eradicate this practice.

The hallmark of chlamydial infection is the development of upper genital pathology in the form of hydrosalpinx and oviduct and/or tubal dilatation. Although molecular events leading to genital tissue presentation and cellular architectural remodelling are unclear, early-stage host immune responses are believed to contribute to these long-term sequelae. Recently, we reported the contribution of selected infection-associated microRNAs (miRs) in the generation of host immunity at early-stage infection (day 6 after intravaginal Chlamydia muridarum challenge in C57BL/6 mice). In this report, we describe the contribution of an infection-associated microRNA, i.e. miR-214, to host immunity. Chlamydia muridarum infection in the C57BL/6 mouse genital tract significantly down-regulated miR-214 while up-regulating intracellular adhesion molecule 1 (ICAM1) gene expression. These in vivo observations were confirmed by establishing direct regulation of ICAM-1 by miR-214 in ex vivo genital cell cultures in the presence of miR-214 mimic and inhibitor. Because, ICAM-1 contributes to recruitment of neutrophils following infection, we also demonstrated that alteration of ICAM1 by miR-214 in interleukin-17A-deficient (IL-17A−/−) mice correlated with reduction of neutrophils infiltrating genital tissue at day 6 after challenge. Additionally, these early-stage events resulted in significantly decreased genital pathology in IL-17A−/− mice compared with C57BL/6 mice. This report provides evidence for early-stage regulation of ICAM1 by microRNAs, resulting in reduction of genital pathology associated with chlamydial infection. PMID:25865776

Abstract Alcohol abuse is a widespread problem among those at risk for and living with HIV and can impact transmission and disease progression. In this study we sought to use the simian immunodeficiency virus (SIV)-macaque model to evaluate the immunological and virological changes in the genital microenvironment of females exposed to chronic alcohol. Female rhesus macaques were treated with alcohol (n=6) or isocaloric sucrose (n=6) for 3 months and then inoculated with SIVmac251. To assess the effects of chronic alcohol on SIV disease and the genital microenvironment, we quantified plasma and genital SIV levels, measured inflammatory cells in genital fluids, and characterized microbial flora by gram stains over 10 weeks post-SIV infection. Following 3 months of alcohol/sucrose treatment, significant differences were observed in the vaginal microenvironment of alcohol-treated animals as compared to controls. Microbial flora of alcohol-treated animals had decreased levels of lactobacillus morphotypes and increased levels of gram-positive cocci relative to sucrose controls. Alcohol-treated animals were also more likely to have white blood cells in vaginal fluids prior to SIV inoculation, which persisted through viral set point. Similar levels of cell-free SIV were observed in plasma and vaginal fluids of both groups, but alcohol-treated animals had a higher incidence and levels of cell-associated SIV shed in vaginal secretions. Chronic alcohol treatment negatively impacts the genital microenvironment prior to and over the course of SIV infection and may increase the risk of genital virus shedding and transmission.

The presence of surface-active material in the lung alveolus has been known for several decades as being essential for normal lung function. Surfactant is essential for reducing the surface tension at the alveolar air-liquid interface. Pulmonary surfactant is composed of 90% lipids and 10% proteins. There are four non-serum proteins surfactant protein-A (SP-A), surfactant protein-B (SP-B), surfactant protein-C (SP-C) and surfactant protein-D (SP-D) named in chronologic order of discovery. Lung SP-A and SP-D belong to a family of collagen-containing C-type lectin family called collectins. The host defence and controlling inflammatory processes of the lung are the major functions of SP-A and SP-D. SP-A and SP-D were originally demonstrated in alveolar type II cells, but recent studies have shown extrapulmonary expression of SP-A and SP-D indicating systemic roles of these proteins. Present study describes the presence of SP-A and SP-D in the mare genital tract, vulva, vagina, ovarium, uterus and tuba uterina using immunohistochemistry and Western blotting. The aim of this study was to characterize surfactant proteins in terms of: (i) whether surfactant proteins were present in the various structures of the mare genital system, (ii) if so, identifying and locating the surfactant proteins and finally (iii) determining the differences from those previously characterized for the lung. Although beyond the scope of this report, it is recognized that there are also some potential implications for better defining the reproductive defence mechanisms in mare. Therefore, genital system organs and tissues from mares were examined. We were able to show that proteins reactive with surfactant-specific antibodies were present in the mare genital tract. Thus, surfactant proteins are present not in just lamellar bodies associated with lung, but also genital system of mare.

Genital inflammation is a key determinant of human immunodeficiency virus (HIV) transmission, and may increase HIV-susceptible target cells and alter epithelial integrity. Several genital conditions that increase HIV risk are more prevalent in African, Caribbean, and other black (ACB) women, including bacterial vaginosis and herpes simplex virus type-2 (HSV-2) infection. Therefore, we assessed the impact of the genital microbiota on mucosal immunology in ACB women and microbiome-HSV-2 interactions. Cervicovaginal secretions and endocervical cells were collected by cytobrush and Instead Softcup, respectively. T cells and dendritic cells were assessed by flow cytometry, cytokines by multiplex enzyme-linked immunosorbent assay (ELISA), and the microbiota by 16S ribosomal ribonucleic acid gene sequencing. The cervicovaginal microbiota of 51 participants were composed of community state types (CSTs) showing diversity (20/51; 39%) or predominated by Lactobacillus iners (22/51; 42%), L. crispatus (7/51; 14%), or L. gasseri (2/51; 4%). High-diversity CSTs and specific bacterial phyla (Gardnerella vaginalis and Prevotella bivia) were strongly associated with cervicovaginal inflammatory cytokines, but not with altered endocervical immune cells. However, cervical CD4+ T-cell number was associated with HSV-2 infection and a distinct cytokine profile. This suggests that the genital microbiota and HSV-2 infection may influence HIV susceptibility through independent biological mechanisms.

The aim of the present study was to locate the sensory and autonomic ganglia innervating the female genital musculature in pigs. The retrograde neuronal tracers horseradish peroxidase (HRP) or fast blue (FB) were injected into the left retractor clitoridis muscle (RCM), which was treated as a typical model of the genital smooth musculature. Labelled cells were found in ipsilateral dorsal root ganglia Sl–S4, in bilateral sympathetic paravertebral ganglia from L5–L6 or L6–L7 to S3 and in the left and right caudal mesenteric ganglion. In two of the five animals treated, presumably preganglionic parasympathetic cells were labelled in the ipsilateral intermediate grey substance of the segments Sl–S2. PMID:11554508

Carcinosarcoma, also known as mixed mesodermal tumor or malignant mixed Mullerian tumor (MMMT) is a pathological entity combining a sarcomatous and a carcinomatous component. Found in thoracic, digestive, genitourinary, liver or skin locations, the most common location is the female genital tract. In gynecological tumors, carcinosarcoma accounts for about 2-5% of endometrial cancers, and 1% of ovarian cancers. To date, there is no consensus on the therapeutic strategy. It relies mostly on maximum cytoreductive surgery. Adjuvant therapy remains controversial, and few prospective studies investigating its interest. Retrospective studies show the benefits of adjuvant chemotherapy based on platinum in most cases. Radiation therapy has a place in the adjuvant situations of endometrial and cervical carcinosarcoma. A more detailed pathological knowledge, and the use of targeted therapies may be promising in this histological subtype whose prognosis remains very poor. The objective of this study is to present the main principles of carcinosarcoma management in female genital tracts, describing pathological and prognostic features at the same time.
Several major breakthroughs have occurred in our understanding of the epidemiology, immunology and biological behavior of the human herpes virus I and II. The family physician, however, is still confronted with four basic clinical situations: patients who present with a genital erosion or ulcer, affected patients in the reproductive age group, patients who ask if herpes causes cervical cancer, and patients who are very troubled by endless recurrences. As syphilitic chancre is becoming rare, the family physician has to recognize the increasing importance of herpes viruses in the etiology of the genital erosion-ulcer syndrome to acquire the clinical and laboratory skills to make that distinction. The prevention of neonatal disease is now possible in the majority of cases provided that pregnancies at risk are identified. Adequate virological surveillance should make it possible to virtually eliminate the disease. The evidence for the oncogenecity is circumstantial. Potential intra- and interpersonal effects of the disease are outlined. ImagesFig. 1Fig. 3 PMID:21286567

Although genital tuberculosis is a condition that is prevalent worldwide, it is still a diagnostic dilemma. This study aimed to find an effective diagnostic modality for the condition. A total of 100 infertile women were clinically evaluated with haemoglobin estimation, total and differential count, Mantoux test, tubercle bacilli enzyme-linked immunosorbent assay (TB ELISA), hysterosalpingography, pelvic ultrasonography, laparohysteroscopy, premenstrual endometrial biopsy for histopathology, culture and tubercle bacilli polymerase chain reaction (TBPCR). The womens' Day 2 hormonal profile (luteinising, follicle-stimulating, prolactin and thyroidstimulating hormones) and their husbands' semen analysis were also conducted. A total of 58 women had primary infertility and 42 had secondary infertility. Female factor infertility was present in 63 percent of the cases (mostly tubal; 45.97 percent). 26 women tested positive for endometrial TBPCR. Erythrocyte sedimentation rate, Mantoux test, TB ELISA and hysterosalpingography were found to have high negative predictive value (greater than 80 percent), while the positive predictive value was 35-45 percent. Laparoscopy findings were suggestive of tuberculosis in 13 percent of the women, out of which 83.3 percent were positive for endometrial TBPCR. Hysteroscopy revealed intrauterine adhesions in 34.8 percent of the women, with 68.8 percent being positive for tubercular bacilli. Our study established that in cases of genital tuberculosis, the use of expensive endometrial TBPCR tests may be avoided with a detailed workup, which would also help in the institution of anti-tubercular treatment in early disease, thus enhancing the chance of pregnancy.

According to 1991 census data, 72,285 East Africans are residing in Canada. Many female immigrants underwent female genital mutilation (FGM) in their countries of origin. This article, prepared by a Somalian midwife and health educator, describes FGM and its implications for obstetric-gynecologic care in Canada. Canadian obstetricians, especially males, must be sensitive to the cultural backgrounds of women who present with FGM and keep in mind that these women are reluctant to expose their genitals. Fear that they will be denied the right to natural childbirth prevents many women with FGM from presenting to a hospital. Medical mismanagement of women with FGM during childbirth can result in complications such as urine retention, perineal tears, and infection. Although infibulation after childbirth is customary for women with FGM, physicians in Ontario are authorized only to repair the surgically incised area. The Council of the College of Physicians and Surgeons of Ontario has designated performance of FGM by a Canadian physician as professional misconduct. Several organizations in Ontario are available to serve as resources for obstetricians who care for women with FGM. The Toronto Birth Control and Venereal Disease Information Center offers classes on childbirth and sexuality and contraception counseling to women with FGM.

A half billion people have genital herpes infections worldwide. Approximately one-fifth of American women between ages 14 and 49 are HSV-2 seropositive. The development of an effective genital herpes vaccine is a global health necessity based on the mental anguish genital herpes causes for some individuals, the fact that pregnant women with genital herpes risk transmitting infection to their newborn children, and the observation that HSV-2 infection is associated with a 3-fold to 4-fold increased probability of HIV acquisition. We review the strengths and limitations of preclinical animal models used to assess genital herpes vaccine candidates and the goals of prophylactic and therapeutic vaccines. We also discuss the current pipeline of vaccine candidates and lessons learned from past clinical trials that serve as a stimulus for new strategies, study designs and endpoint determinations.

Abstract Adult-onset Still disease (AOSD) is a systemic autoimmune disease (AIID) that can develop after exposure to infectious agents. Genital human papillomavirus (HPV) infection has been reported to induce or exacerbate AIIDs, such as systemic lupus erythematosus (SLE). No guidelines are available for the management of genital warts in AOSD. Case report and literature review. We report a patient who was diagnosed AOSD in the setting of refractory and recurrent genital HPV infection, demonstrating a possible link between HPV infection and AOSD. In addition, we also discuss the management of genital warts in patients with AOSD. To the best of our knowledge, no previous cases of AOSD with genital HPV infection have been reported in literature. We then conclude that the patient AOSD may be triggered by primary HPV infection. Larger number of patient samples is needed to confirm whether HPV could trigger AOSD. PMID:27082556

The population explosion and unintended pregnancies, sexually transmitted diseases including human immunodeficiency virus, and cervical cancer, are major challenges to health worldwide. Their prevention might be achieved through vaccination-based approaches to activate specific immunity against pathogen- or fertility-associated antigens in the female genital tract (FGT). This article aims to review methodologies for enhancing adaptive immunity in the FGT to maximize the response to vaccination. Most components of the adaptive and innate mucosal immune system are present in the FGT and several features are common with the nasopharynx/bronchial and gastrointestinal tracts. In contrast to other mucosal sites, the FGT has minimal local lymphoid tissue. Other sites primarily produce IgA and IgM while in the FGT, especially the vaginocervix, IgG is the predominant immunoglobulin secreted. In rodents, data exist to substantiate a common mucosal immune system interconnecting the nasal/bronchial, gastrointestinal, and female genital tracts. The intranasal route seems the most efficacious to induce an immunity in the FGT especially when combined with a systemic or parenteral route. In humans, for induction of secretory IgA and IgG antibodies in the FGT, immunization by the nasal or the vaginal route is effective. In vaginal immunization, a strong and consistent antibody response is best achieved following vaccination during the follicular phase of the menstrual cycle. Antibodies administered systemically percolate into the FGT and can provide immunoprotection against target molecules or cells. Thus, as well as active immunization using selected routes, the passive immunization approach may provide a viable alternative to vaccinology for future development.

Viral vaccines have traditionally protected against disease, but for viruses that establish latent infection, it is desirable for the vaccine to reduce infection to reduce latent infection and reactivation. While seroconversion has been used in clinical trials of herpes simplex virus (HSV) vaccines to measure protection from infection, this has not been modeled in animal infection systems. To measure the ability of a genital herpes vaccine candidate to protect against various aspects of infection, we established a non-lethal murine model of genital HSV-2 infection, an ELISA assay to measure antibodies specific for infected cell protein 8 (ICP8), and a very sensitive qPCR assay. Using these assays, we observed that immunization with HSV-2 dl5-29 virus reduced disease, viral shedding, seroconversion, and latent infection by the HSV-2 challenge virus. Therefore, it may be feasible to obtain protection against genital disease, seroconversion and latent infection by immunization, even if sterilizing immunity is not achieved.

Vitiligo has a major effect on sexual health because of the disfiguring skin lesions affecting self-image and self-esteem. However, this topic has not explored. This article aimed to assess the effect of vitiligo on genital self-image, sexual function, and quality of life in female patients. This cross-sectional study included 50 sexually active women with vitiligo and 25 women without vitiligo. All participants subjected to full history taking and examination. Extent of vitiligo was assessed with the Vitiligo Area Scoring Index score, sexual function with the Female Sexual Function Index, genital self-image with Female Genital Self-Image Score and quality of life with the Dermatology Life Quality Index questionnaires. The main outcome measures were correlation between Vitiligo Area Scoring Index, Female Genital Self-Image Score, Female Sexual Function Index, and Dermatology Life Quality Index domains was determined using t test and Pearson correlation. This study revealed a negative correlation between the Vitiligo Area Scoring Index score and sexual satisfaction. Vitiligo Area Scoring Index and Dermatology Life Quality Index score was significantly correlated with Arabic Version of the Female Genital Self-Image Score alone and with Arabic Version of the Female Sexual Functioning Index alone and with both the Arabic Version of the Female Genital Self-Image Score and the Arabic Version of the Female Sexual Functioning Index (p <.05). Sexual and psychological assessment of patients with vitiligo is imperative to improve outcomes and increase patients' compliance with treatment.

Bacterial infections remain a major cause of morbidity and mortality in newborn infants. To determine the bacterial ecology and pathological status of the genital organs during the last trimester of pregnancy and the germs of the following early-onset neonatal sepsis, in order to evaluate the risk of materno-foetal infections and to find out a drug prophylaxis. Vaginal and endocervical samples, usually taken during the first trimester of pregnancy were delayed and taken during the last trimester of pregnancy. A macroscopic examination described the aspect of the vagina, the cervix uteri, leukorrhea and of possible inflammatory lesions or ulcerations. A microscopic examination searched for parasites, epithelial cells, clue cells and leukocytes. The appropriate bacteriological cultures were performed after reading the Gram stain and scoring the vaginal flora. The clinical and cytobacteriological aspects were used to identify the bacterial ecology and the pathological genital states. An exploration was carried out in every newborn suspected of infection. Genital samples were collected from 306 pregnant women. Among them, 118 were at 29-32 weeks of gestation, 104 at 33-36, and 84 at 37-40. The most frequent germs were C. albicans (33,5%), Enterbacteriaceae (20.3%) including E. coli (10.9%), S. aureus (15.4%), Gardnerella (13.6%), and Trichomonas (10.6%), in monomicrobian (79.2%) and polymicrobian carriage (20.8%). Lower genital tract pathological states such as vaginitis (29.4%), bacterial vaginosis (21.5%) or endocervicitis (10.4%), asymptomatic bacterial carriage (23.5%) and normal genital flora (15%) were identified. These pregnancies led to 334 live births with 27 cases of early-onset neonatal sepsis to which endocervicitis (25%) and vaginosis (19,7%) were most often linked. Genital samples at the last trimester of pregnancy could evaluate the risk of maternofoetal infections and allow to adapt a drug prophylaxis of Enterobacteriaceae, the most frequent germ of

Warts are abnormal skin growths caused by human papilloma virus (HPV) infections within the skin of patients. Genital warts usually appear in the perianal and perigenital regions. Asymptomatic warts may be activated after years and may damage natural immunity. The inflammation that occurs during this process may lead to an imbalance between the prooxidant and the antioxidant systems. The aim of this study was to investigate erythrocyte glutathione peroxidase (GSH-Px) activity, serum paraoxonase enzyme levels, and oxidative stress levels in patients with genital warts. In total, 32 patients with genital warts and 35 healthy subjects were included in this study. Erythrocyte GSH-Px activity, serum catalase activity, and paraoxonase enzyme, and malondialdehyde (MDA) levels were determined. Erythrocyte GSH-Px activity, serum MDA levels, and catalase activity were significantly higher in patients with genital warts than in controls (P < 0.01, P < 0.05, and P < 0.05, respectively). However, serum paraoxonase enzyme levels were not significantly different between groups (P > 0.05). Serum triglyceride levels were significantly lower in patients with genital warts than in controls (P < 0.01). However, there were no statistically significant differences between groups with respect to total cholesterol, high-density lipoprotein cholesterol, or low-density lipoprotein cholesterol levels (all P > 0.05). Our data suggest that oxidative stress is increased in genital warts. Increased oxidative stress levels may contribute to the pathogenesis of genital warts, and prolonged HPV infection due to chronic inflammation could also affect oxidative stress.

New colposcopic protocols for US forensic examiners enable documentation of genital trauma in 87-92% of rape victims--a significant improvement over protocols based on gross visualization or toluidine blue dye enhancement. It remains unresearched, however, whether colposcopic genital findings in sexual assault victims differ substantially from those in women who have had consensual intercourse. Thus, the type, extent, and distribution of genital injuries observed through colposcopy in 311 rape victims seen by the San Luis Obispo (California) County's Suspected Abuse Response Team in 1985-93 were compared to genital changes in 75 healthy women who had engaged in consensual intercourse in the past 24 hours. 213 assault victims (68%) had evidence of anogenital trauma. Among the 178 women (57%) with nongenital trauma, 132 (74%) also had genital injury (tears, ecchymoses, abrasions, redness, and swelling). The most common trauma site was the posterior fourchette (70%). Examination findings were significantly greater at 24 hours after rape than at 72 hours or more, but almost half the women seen at 72 hours or more after assault had positive genital findings. The injury pattern was not affected by age. In the consensual sex group, trauma was noted in eight women (11%). The proportion with genital injury was significantly higher for women reporting nonconsensual sex than those reporting consensual sex.

To examine the risks of genital herpes and antiherpes treatment during pregnancy in relation to preterm delivery (PTD), we conducted a multicenter, member-based cohort study within 4 Kaiser Permanente regions: northern and southern California, Colorado, and Georgia. The study included 662,913 mother-newborn pairs from 1997 to 2010. Pregnant women were classified into 3 groups based on genital herpes diagnosis and treatment: genital herpes without treatment, genital herpes with antiherpes treatment, and no herpes diagnosis or treatment (unexposed controls). After controlling for potential confounders, we found that compared with being unexposed, having untreated genital herpes during first or second trimester was associated with more than double the risk of PTD (odds ratio (OR) = 2.23, 95% confidence interval (CI): 1.80, 2.76). The association was stronger for PTD due to premature rupture of membrane (OR = 3.57, 95% CI: 2.53, 5.06) and for early PTD (≤35 weeks gestation) (OR = 2.87, 95% CI: 2.22, 3.71). In contrast, undergoing antiherpes treatment during pregnancy was associated with a lower risk of PTD compared with not being treated, and the PTD risk was similar to that observed in the unexposed controls (OR = 1.11, 95% CI: 0.89, 1.38). The present study revealed increased risk of PTD associated with genital herpes infection if left untreated and a potential benefit of antiherpes medications in mitigating the effect of genital herpes infection on the risk of PTD.

Female genital mutilation/cutting (FGM/C) is a cultural practice involving several types of external female genitalia cutting. FGM/C is known to occur in all parts of the world but is most prevalent in 28 countries in Africa and the Middle East and among immigrant communities in Europe, Australia, New Zealand, Canada, and the United States. Studies of FGM/C suffer from many methodological problems including inadequate analysis and an unclear reporting of results. The evidence to link FGM/C to infertility is weak. The management of epidermal clitoral inclusion cysts includes expensive investigations like comprehensive endocrinology tests and MRI resulting in unnecessary anxiety due to delay in surgical treatment. Similarly, unnecessary cesarean sections or rupture of the infibulation scar continue to occur because of the inadequate use of intrapartum defibulation. A significant amount of efforts is required to improve and correct the inadequate care of FGM/C women and girls.

To present the findings of sarcoidosis on female genital tract. Review. Department of Obstetric and Gynecology, Silesian Hospital Opava. Overview of published findings from case studies. Sarcoidosis is a multisystem granulomatous disorder of unclear cause. It typically involves the lymph nodes of mediastinum, predominantly billateral and/or pulmonary infiltrates. We find extrapulmonary involvement in 30-50% of cases. Sarcoidosis of the female reproductive system is a rare, it represent less than 1% cases of sarcoidosis. Lesions there may affect any organ, including the vulva, vagina, cervix, uterus, fallopian tube and ovary, but also for example placenta and breast. There is also recorded the incidence of multiple localization on female genitalia. Since sarcoidosis of this area is so rare, often proceeds asymptomatic and recognized only as an incidental finding, there are mention only the case histories in literature yet.Clinical symptoms may be non-specific, often imitating a tumor, or tend to be specific, depending on the localization of disability such as perineal pain, pain in the scar after the previous birth trauma, persistent pruritus, itching, irritation, dyspareunia, menstrual cycle disorders, menorrhagia, metrorrhagia, postmenopausal bleeding, amenorrhoe, abdominal pain, endometrial polypoid lesions, recurrent or persistent serometra or discharge. The diagnosis is made up of histologically - we are demonstrating noncaseating granulomas.The therapy is difficult, there are no available official guidelines. If the lesions are clinically silent, we can observed them because they may spontaneously disappear. If we are embarking on medical therapy, we start from a local application, and if this is unsuccessful then we approach the systemic administration. Corticosteroids are the drug of choice. If we diagnose the sarcoidosis of the female genital organs we must exclude systemic disease of sarcoidosis. The prognosis of disease is good.

The effects of hypothyroidism on the female genital tract of gerbils have been studied. Hypothyroidism was produced by (a) surgical ablation, and (b) pharmacological suppression of the gland. Hypothyroidism resulted in atrophic ovaries. Follivular development was severely arrested, with most of the follicles showing atresia. Distinct effects were produced upon the uterine physiology. Uterine regression was conspicuous in thyroidectomized females. Hypothyroidism resulted in a decreased RNA, protein, sialic acid and glycogen concentration of the uterus. Vaginal RNA, protein and sialic acid contents were low after thyroidectomy. The vaginal cytology showed a constant pattern of its cells, i.e. dioestrous. L-thyroxine treatment restores the biochemical changes of uterus and vagina to subnormal levels in thyroidectomized animals. It is concluded that hypothyroidism affected the weight, cytology and biochemistry of the female genital tract of gerbils.

A study of human papilloma virus (HPV) specific cellular and humoral immunity in 30 patients with genital warts is reported. By in vivo testing with purified, inactivated plantar wart virus, a cell-mediated immunity to HPV was determined in 60% of patients. Circulating antibodies, evaluated by immunofluorescence testing, were rare, but these increased after an intradermal test had been carried out, especially in patients with a positive skin test, suggesting a booster effect. No significant difference was found between this group of patients and those having skin warts. Our results showed a specific immune response to HPV in most patients, confirming the role of the viral agent in the induction of genital warts. Images PMID:207383

The current study evaluates combined aerosol-vaginal delivery of a MOMP-based Chlamydia trachomatis (serovar E) DNA vaccine in a pig genital challenge model. Most non-replicating antigens are rather poor mucosal immunogens in comparison to replicating antigens. Therefore, a mucosal administered DNA vaccine, which actually mimics a live vaccine, could be promising. Protection was promoted by plasmids encoding the porcine granulocyte macrophage-colony stimulating factor (pcDNA3.1zeo::GM-CSF), the Escherichia coli thermo-labile enterotoxin (LT) subunit A (plasmid PJV2004::LTa) and subunit B (plasmid PJV2005::LTb). Mucosal C. trachomatis DNA vaccination induced significant protection against genital C. trachomatis challenge although the infection could not be eradicated. Intradermal immunization was significantly less efficient in protecting experimentally infected pigs. Protection was correlated with efficient T cell priming and significantly higher serum IgA titers following primo vaccination. Copyright © 2012 Elsevier Ltd. All rights reserved.

The aim of the present study was to reveal the characteristic features of genital Chlamydia suis infection and re-infection in female pigs by studying the immune response, pathological changes, replication of chlamydial bacteria in the genital tract and excretion of viable bacteria. Pigs were intravaginally infected and re-infected with C. suis strain S45, the type strain of this species. We demonstrated that S45 is pathogenic for the female urogenital tract. Chlamydia replication occurred throughout the urogenital tract, causing inflammation and pathology. Furthermore, genital infection elicited both cellular and humoral immune responses. Compared to the primo-infection of pigs with C. suis, re-infection was characterized by less severe macroscopic lesions and less chlamydial elementary bodies and inclusions in the urogenital tract. This indicates the development of a certain level of protection following the initial infection. Protective immunity against re-infection coincided with higher Chlamydia-specific IgG and IgA antibody titers in sera and vaginal secretions, higher proliferative responses of peripheral blood mononuclear cells (PBMC), higher percentages of blood B lymphocytes, monocytes and CD8⁺ T cells and upregulated production of IFN-γ and IL-10 by PBMC.

Although HSV-2 is the major cause of genital lesions, HSV-1 accounts for half of new cases in developed countries. Three healthy SHIV-SF162P3-infected Indian rhesus macaques were inoculated with 4×10(8) pfu of HSV-1 twice, with the second inoculation performed after the vaginal mucosa was gently abraded with a cytobrush. HSV-1 DNA was detected in vaginal swabs 5 days after the second but not the first inoculation in all three macaques. An increase in inflammatory cytokines was detected in the vaginal fluids of the animals with no or intermittent shedding. Higher frequency of blood α4 β7(high) CD4(+) T cells was measured in the animals with consistent and intermitted shedding, while a decrease in the frequency of CD69(+) CD4(+) T cells was present in all animals. This macaque model of genital HSV-1 could be useful to study the impact of the growing epidemic of genital HSV-1 on HIV infection. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

An unusually high prevalence of metastatic urogenital carcinoma has been observed in free-ranging California sea lions stranded off the coast of California in the past two decades. No cases have been reported for sea lions in the relatively unpolluted Gulf of California. We investigated occurrence of genital epithelial transformation in 60 sea lions (n=57 pups and 3 adult females) from the Gulf of California and examined whether infection by a viral pathogen previously found to be associated with urogenital carcinoma accounted for such alterations. We also explored the contribution of MHC class II gene expression on transformation. Cellular alterations, such as squamous cell atypia (ASC), atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intraepithelial lesions were observed in 42% of the pups and in 67% of the adult females. Normal genital epithelium was more common in male than female pups. ASC was five times more likely to occur in older pups. Epithelial alterations were unrelated to infection by the potentially oncogenic otarine type I gammaherpesvirus (OtHV-1), but ASCUS was more common in pups with marked and severe inflammation. Expression of MHC class II DRB loci (Zaca DRB-D) by peripheral antigen-presenting leucocytes showed a slightly 'protective' effect for ASC. We propose that transformation of the California sea lion genital epithelium is relatively common in young animals, increases with age and is probably the result of infection by an unidentified pathogen. Expression of a specific MHC class II gene, suggestive of presentation of specific antigenic peptides to immune effectors, appears to lower the risk of transformation. Our study provides the first evidence that epithelial transformation of the California sea lion genital tract is relatively common, even from an early age, and raises questions regarding differences in sea lion cancer-detection and -repair success between geographical regions.

The clinical effect of imiquimod stems from cytokine-induced activation of the immune system. A randomized study was conducted to study the efficacy and safety of daily applications of 5% imiquimod cream in female patients with external genital warts and molluscum contagiosum (MC). The clearance rate of lesions was 75% in genital MC patients and 50% in patients with genital warts. Erythema was the commonest adverse reaction seen in 24% patients with the use of 5% imiquimod. Other side effects were excoriation seen in 16% patients, erosions in 10% patients, excoriation in 6% patients and pain was seen in 4% patients. PMID:21938126

Objective To elucidate which anatomical sites need to be sampled to detect human papillomavirus (HPV) infection in the lower male genital tract. Method In an HPV survey of Mexican soldiers (median age 24 years; range 16–50 years), a cell sample from 2 cm deep into the distal urethra (group 1; n = 168 men), or 0.5 cm deep into the meatus urethralis (group 2; n = 414 men) was collected, along with a sample from the external genitalia. The different samples were tested for 27 HPV types using a polymerase chain reaction based strip assay. Results HPV DNA was detected more frequently in external genitalia samples (46.4%) than in the urethra (20.8%) or meatus samples (12.1%). Lack of samples from the urethra or meatus would have led to 5.1% and 1.5% false HPV negative results, respectively. The most frequently detected high risk HPV types (HPV 59, 52, 51, and 16) were similar in different sites, whereas low risk types were found rarely in urethra samples. Conclusions The addition of cell samples from the meatus to those from external genitalia contributed negligibly to the evaluation of the prevalence of HPV in men. HPV detection was slightly improved by the addition of urethra samples, but the gain may not justify the discomfort of the procedure in large epidemiological studies. PMID:16461598

Genital powder use has been associated with risk of epithelial ovarian cancer in some, but not all, epidemiologic investigations, possibly reflecting the carcinogenic effects of talc particles found in most of these products. Whether risk increases with number of genital-powder applications and for all histologic types of ovarian cancer also remains uncertain. Therefore, we estimated the association between self-reported genital powder use and epithelial ovarian cancer risk in eight population-based case-control studies. Individual data from each study was collected and harmonized. Lifetime number of genital-powder applications was estimated from duration and frequency of use. Pooled odds ratios were calculated using conditional logistic regression matched on study and age and adjusted for potential confounders. Subtype-specific risks were estimated according to tumor behavior and histology. 8,525 cases and 9,859 controls were included in the analyses. Genital powder use was associated with a modest increased risk of epithelial ovarian cancer (odds ratio 1.24, 95% confidence interval 1.15–1.33) relative to women who never used powder. Risk was elevated for invasive serous (1.20, 1.09–1.32), endometrioid (1.22, 1.04–1.43), and clear cell (1.24, 1.01–1.52) tumors, and for borderline serous tumors (1.46, 1.24–1.72). Among genital powder users, we observed no significant trend (p=0.17) in risk with increasing number of lifetime applications (assessed in quartiles). We noted no increase in risk among women who only reported non-genital powder use. In summary, genital powder use is a modifiable exposure associated with small-to-moderate increases in risk of most histologic subtypes of epithelial ovarian cancer. PMID:23761272

To compare the frequency of genital lichen sclerosus (LS) in patients with morphea with that of control patients. A prospective multicenter study. Four French academic dermatology departments: Strasbourg, Montpellier, Tenon Hospital Paris, and Henri Mondor Hospital Créteil. Patients were recruited from November 1, 2008, through June 30, 2010. Seventy-six patients with morphea and 101 age- and sex-matched controls, who underwent complete clinical examination, were enrolled. A complete clinical examination and, if deemed necessary, a cutaneous biopsy. The frequency of genital LS. There were 58 women and 18 men (a 3:1 ratio) with a median age of 59 years. Mean (range) age at diagnosis was 54 (13-87) years. Forty-nine patients had plaque morphea, 9 had generalized morphea, and 18 had linear morphea. Three patients (3%) in the control group and 29 patients (38%) with morphea had LS (odds ratio, 19.8; 95% CI, 5.7-106.9; P < .001). Twenty-two patients with plaque morphea (45%) and only 1 patient with linear morphea (6%) had associated genital LS. Genital LS is significantly more frequent in patients with morphea than in unaffected individuals. Forty-five percent of patients with plaque morphea have associated LS. Complete clinical examination, including careful inspection of genital mucosa, should therefore be mandatory in patients with morphea because genital LS bears a risk of evolution into squamous cell carcinoma and thus needs treatment with topical corticosteroids.

Female genital cutting (FGC), commonly called female genital mutilation, affects millions of women but is poorly understood by many health care providers. FGC procedures intentionally alter the female genital organs for nonmedical reasons and include partial or total removal of female genital organs. These procedures, which have no medical value, are usually done between birth and puberty. Health consequences vary in severity but can be devastating. Women who have experienced FGC may be reluctant to seek health care or to disclose their condition to providers. Suggestions for culturally competent care of women who have experienced FGC are outlined, focusing on understanding the cultural beliefs and values of women who have undergone these procedures and providing informed and sensitive care. © 2015 AWHONN.

Cutis laxa (CL) is an extremely inherited or acquired connective tissue disorder characterised by a markedly reduced systemic elastin content. Genital abnormalities in patients with CL have been rarely reported. We report such a case in a 48-year-old CL patient affected by genital prolapse, focusing on immunohistological and molecular biology assessment of elastin and collagen type I, III, VI content in the main uterine ligaments. The woman was referred to our department for the onset of a rapidly progressing genital prolapse and urinary incontinence. The patient underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy and sacrocolpopexy. Punch biopsies from both cardinal and uterosacral ligaments revealed a dramatic reduction in elastin and an increase in collagen type VI content. The present report seems to underline the central role exerted primarily by elastin in the supportive connective tissue and might contribute to the knowledge of extracellular matrix abnormalities at the basis of genital abnormalities in CL patients.

Traditional female genital circumcision, or female genital mutilation, performed upon women in some non-Western cultures has provoked considerable international controversy since the late 1970s. Western feminists, physicians, and ethicists condemn such practice. Having made moral judgement against female genital mutilation, however, what is the next step? There is clearly an impasse between cultural relativism on the one hand and universalism on the other. Those at the forefront of the debate on female genital mutilation must learn to work respectfully with, instead of independently of, local resources for cultural self-examination and change. The authors discuss cultural relativism and moral universalism; female circumcision in sections on epidemiology, health effects, and culture, religion, and social change; the debate historically; the response of Arab and African women; and moving beyond the impasse.

Understanding women's perspectives of female genital cutting is particularly critical for understanding the roots of the problem and enhancing effectiveness of any prevention program. Very limited research has examined how people in Iraqi Kurdistan Region think about this practice. This study aimed to explore the perspectives of women of female genital cutting with the aim of uncovering discrepancies and commonalities between women of different socio-educational groups. An explorative study using Q-methodology was conducted with 29 women from different educational and socio-economic statuses in Erbil, the main city of the Iraqi Kurdistan Region. Participants were asked to rank-order a set of 39 statements about different aspects of female genital cutting into a distribution on a scale of nine from "disagree most" to "agree most". By-person factor analysis was performed with factors or latent viewpoints extracted through centroid method and varimax rotation. A four-factor solution and one consensus perspective provided the best conceptual fit for the women's perspectives about female genital cutting. Factor 1, entitled "positive cultural tradition", centers on recognizing female genital cutting as a positive cultural aspect and an essential part of the Kurdish culture. Factor 2, "active opponents", positions around actively opposing the practice of female genital cutting and considering the practice a violation of human rights. Factor 3, "role of law", stresses the importance of developing and enforcing law for combating female genital cutting. Factor 4, "health concerns and passive opposition", represents the perspectives of recognizing the importance of health concerns resulting from female genital cutting and opposition of the practice but not in an active manner. A consensus perspective, "marital role", centers primarily on lack of effect of female genital cutting on women's marital role. Female genital cutting is still a contentious issue among women in Iraqi

While Chlamydia trachomatis infections are frequently asymptomatic, mechanisms that regulate host response to this intracellular Gram-negative bacterium remain undefined. This investigation thus used peripheral blood mononuclear cells and endometrial tissue from women with or without Chlamydia genital tract infection to better define this response. Initial genome-wide microarray analysis revealed highly elevated expression of matrix metalloproteinase 10 and other molecules characteristic of Type 2 immunity (e.g., fibrosis and wound repair) in Chlamydia-infected tissue. This result was corroborated in flow cytometry and immunohistochemistry studies that showed extant upper genital tract Chlamydia infection was associated with increased co-expression of CD200 receptor and CD206 (markers of alternative macrophage activation) by endometrial macrophages as well as increased expression of GATA-3 (the transcription factor regulating TH2 differentiation) by endometrial CD4+ T cells. Also among women with genital tract Chlamydia infection, peripheral CD3+ CD4+ and CD3+ CD4- cells that proliferated in response to ex vivo stimulation with inactivated chlamydial antigen secreted significantly more interleukin (IL)-4 than tumor necrosis factor, interferon-γ, or IL-17; findings that repeated in T cells isolated from these same women 1 and 4 months after infection had been eradicated. Our results thus newly reveal that genital infection by an obligate intracellular bacterium induces polarization towards Type 2 immunity, including Chlamydia-specific TH2 development. Based on these findings, we now speculate that Type 2 immunity was selected by evolution as the host response to C. trachomatis in the human female genital tract to control infection and minimize immunopathological damage to vital reproductive structures.

A case is presented of a 49-year-old man who amputated his penis following instructions that he had obtained from the Internet. The patient had a long-standing amputee fetish, which evolved into eroticized genital mutilation. The transformation of the preferred fetish occurred in a setting of depression due to environmental stressors. The literature about amputee fetishism, also called "apotemnophilia," is reviewed, and possible connections with the genital mutilation are discussed.

Background: Genital tuberculosis is a chorionic disease and mostly occurs by haematogenous spread from extra genital source like lungs, peritoneum, lymph nodes and bones. Transmission through a sexual intercourse is also possible. Since the majority of patients are in reproductive ages, involvement of fallopian tubes and endometrium cause infertility in patients. Cases: Reviewing 4 cases of female genital tuberculosis, which referred to an infertility treatment center with various symptoms, we encountered various appearances on hysterosalpingography (HSG). Conclusion: The genitourinary tract is the most common site of extra pulmonary TB. The primary focus of genital tuberculosis is fallopian tubes, which are almost always affected bilaterally but not symmetrically. Because of common involvement of fallopian tubes and endometrial cavity, disease causes infertility. Diagnosis is not easy because genital tuberculosis has a wide range of clinical and radiological manifestations with slow growing symptoms. Detailed hysterosalpingography finding may be helpful in better diagnosis of the disease. This case series aims to depict the various hystrosalpingographic appearances and pathology produced by tuberculosis and related literatures are reviewed in order to establish a better diagnostic evaluation of genital tuberculosis.

Genital losses from ritual attacks are often reported in the media and often discussed in the social media but are hardly reported in medical literature. Male genital mutilation (MGM) refers to permanent modification of the external genitalia that involves ablation of genital tissues.When found, it is usually as a consequence of poor circumcision skills, auto mutilation/castration or genital injuries caused by attacks or accidents. Male circumcision on its own is widely regarded as a rather safe and acceptable practice which is known to have some health benefits and in keeping with several religious customs as rite of passage. Outside of professional performed circumcision, MGM is usually associated with dark arts and malicious intentions like witchcraft or as a consequence of torture of prisoners of war for information. In this case we describe a 5-year old Ugandan boy who had his genitals mutilated in bizarre circumstances within a ritual attack. He survived and a urethrostomy was fashioned. There is need to document more of these cases in order to gather enough information to inform prevention and treatment strategies. Issues of hormonal replacement therapy (HRT) and possible sex change require much debate. These genital sex changing operations should preferably be avoided until a child can fully participate in decision making.

We aimed to describe the presentation of long-term complications of female genital mutilation/cutting and the surgical management of clitoral keloids secondary to female genital mutilation/cutting. Twenty-seven women who underwent surgery because of clitoral keloid between May 2014 and September 2015 in Sudan Nyala Turkish Hospital were evaluated in this retrospective descriptive case series study. The prevalence of type 1, type 2, and type 3 female genital mutilation/cutting were 3.7%, 22.2%, and 74.1%, respectively (type 1: 1/27, type 2: 6/27, and type 3: 20/27). All patients had long-term health problems (dysuria, chronic pelvic pain, vaginal discharge, and chronic pruritus) and sexual dysfunction. Keloids were removed by surgical excision. There were no postoperative complications in any patient. Although clitoral keloid lesions can be seen after any type of female genital mutilation/cutting, they usually develop after type 3 female genital mutilation/cutting. Most of these keloids were noticed after menarche. Keloids can be removed by surgical excision and this procedure can alleviate some long-term morbidities of female genital mutilation/cutting.

HIV vaginal transmission accounts for the majority of newly acquired heterosexual infections. However, the mechanism by which HIV spreads from the initial site of viral entry at the mucosal surface of the female genital tract to establish a systemic infection of lymphoid and peripheral tissues is not known. Once the virus exits the mucosa it rapidly spreads to all tissues, leading to CD4+ T cell depletion and the establishment of a viral reservoir that cannot be eliminated with current treatments. Understanding the molecular and cellular requirements for viral dissemination from the genital tract is therefore of great importance, as it could reveal new strategies to lengthen the window of opportunity to target the virus at its entry site in the mucosa where it is the most vulnerable and thus prevent systemic infection. Using HIV vaginal infection of humanized mice as a model of heterosexual transmission, we demonstrate that blocking the ability of leukocytes to respond to chemoattractants prevented HIV from leaving the female genital tract. Furthermore, blocking lymphocyte egress from lymph nodes prevented viremia and infection of the gut. Leukocyte trafficking therefore plays a major role in viral dissemination, and targeting the chemoattractant molecules involved can prevent the establishment of a systemic infection. PMID:28405607

We found that factor H (FH) exists in porcine seminal plasma. Purified FH strongly inhibited serum alternative pathway complement activation against lipopolysaccharide. The molecular weight, pI, and heparin-binding activity of the purified protein were different from those of purified FH from porcine serum. The complement regulatory activity of seminal plasma FH was ∼2-fold stronger than that of serum FH. Treatment of purified serum FH with sialidase and N-glycosidase F gave almost the same results as those of seminal plasma FH. The deletion of sialic acid from the carbohydrate chains of both FHs contributed to heparin-binding and complement regulatory activities. Results of reverse transcriptase-PCR, Western blot analysis, and immunohistochemistry showed that seminal plasma FH is mainly secreted from epithelial cells of the seminal vesicle in male genital tracts. FH was also detected in the outer acrosomal region of ejaculated sperm by immunofluorescence staining, and found that the purified FH from the sperm membrane has the same complement regulatory activity as that of seminal plasma FH. The ejaculated sperm possessing FH in the outer acrosomal region considerably evaded complement attack. We also found that there is strong complement activity in fluids from female genital tract ducts. These findings indicate that FH bound to the outer acrosomal region and soluble FH play important roles in protecting sperm against complement attack in male and female genital tracts. PMID:19920146

Virtually all efforts to generate an effective protection against the life-long, recurrent genital infections caused by HSV-2 have failed. Apart from sexual transmission, the virus can also be transmitted from mothers to neonates, and it is a key facilitator of HIV coacquisition. In this article, we uncover a nanoimmunotherapy using specially designed zinc oxide tetrapod nanoparticles (ZOTEN) with engineered oxygen vacancies. We demonstrate that ZOTEN, when used intravaginally as a microbicide, is an effective suppressor of HSV-2 genital infection in female BALB/c mice. The strong HSV-2 trapping ability of ZOTEN significantly reduced the clinical signs of vaginal infection and effectively decreased animal mortality. In parallel, ZOTEN promoted the presentation of bound HSV-2 virions to mucosal APCs, enhancing T cell-mediated and Ab-mediated responses to the infection, and thereby suppressing a reinfection. We also found that ZOTEN exhibits strong adjuvant-like properties, which is highly comparable with alum, a commonly used adjuvant. Overall, to our knowledge, our study provides the very first evidence for the protective efficacy of an intravaginal microbicide/vaccine or microbivac platform against primary and secondary female genital herpes infections.

Major injuries to the testicles, penis, and genital skin from trauma and infection were seen in 62 patients over a 6-year period (1977 to 1983). Urethral injuries were excluded. In the past blunt testicle injuries were infrequently diagnosed and surgically ignored because of large surrounding hematomas. With the use of real-time ultrasound, 17 of 18 cases of testicle rupture were correctly diagnosed preoperatively. Surgical repair resulted in testicle salvage in 16 patients. Penetrating testicle injuries resulted in a high orchiectomy rate secondary to the infrequently described but recognized entity of self-emasculation in transsexuals. Penile rupture from blunt injuries (8) was successfully repaired and complete function was recovered. Penetrating penile injuries (4) were extensive and involved the urethra in two cases; full function returned after reconstruction. Major skin loss of the penis and/or scrotum (19) occurred from necrotizing fasciitis, burns, avulsion and penetrating injuries. Early debridement, bowel and urinary diversion followed by penile skin grafting, thigh pouches to protect testicles, and scrotal reconstruction resulted in acceptable cosmetic and functional results in all cases of major skin loss.

More than 130 million women worldwide have undergone female genital cutting (FGC). FGC is practiced in parts of Africa and Asia, in societies with various cultures and religions. Reasons for the continuing practice of FGC include rite of passage, preserving chastity, ensuring marriageability, religion, hygiene, improving fertility, and enhancing sexual pleasure for men. The World Health Organization has classified FGC into four types depending on the extent of tissue removed. Immediate complications include hemorrhage, infection, sepsis, and death. Long-term complications include pain, scarring, urinary issues, and poor obstetric and neonatal outcomes. Efforts are being made nationally and internationally to eradicate this practice. In December 2012, the UN General Assembly accepted a resolution on the elimination of FGC. Although it is illegal to perform FGC in the United States, women from countries where the practice occurs have been and are still immigrating here. Many enter as refugees from war-torn, famine-stricken, or politically unstable countries. They bring along with them their cultural pride, health complications, and fears of being judged when visiting a health provider. A deeper understanding of the history, cultural beliefs, medical complications, and methods of surgical reconstruction is necessary to provide culturally and linguistically competent care to this unique group of women.

Female genital mutilation/cutting (FGM/C) is a traditional practice in which the external female genitalia is partially or totally incised or excised for a non-therapeutic reason, usually without the consent of the individual. FGM/C is common in Africa with varying prevalence in different countries, though the incidence is reducing because it is considered a human rights issue with tremendous advocacy for its elimination by mainly nongovernmental organizations. It is mainly underreported in many countries in Africa especially where it has been declared illegal. FGM/C is often performed by a nonmedical practitioner with the aim of fulfilling religious or cultural rites and sometimes for economic benefits with the resultant acute, intermediate and late complications. It is sometimes performed by medical practitioners when it is speciously believed that its medicalization reduces the complications associated with the practice. The sensitivity of FGM/C is amplified when compared to male circumcision and voluntary alterations of the female external genitalia like piercing and tattooing as similar practices. The magnitude of the physical and psychosocial consequences of FGM/C outweighs the presumed benefits of the procedures highlighting the need for improvement of the multiple preventive measures by all the stakeholders and in all the sectors.

The practice of female genital mutilation (FGM) is widespread in Nigeria. This study was conducted to assess the perceptions of FGM among mothers at a primary healthcare centre in Lagos, Nigeria. A convenience sample of 95 mothers completed the pre-tested, semi-structured questionnaires. Data analysis was carried out using descriptive statistics and a chi-square test was used to test for association between variables. Findings showed that the mothers held ambivalent beliefs about the practice. Although over half of the respondents (56.8%) perceived the practice of FGM as not being beneficial, 44.2% thought that uncircumcised girls will become promiscuous. Nearly a third (30.5%) believed that FGM promotes a woman's faithfulness to her husband. About a quarter (26.3%) reported that women who have undergone FGM are not at any risk of gynaecological complications. There was a significant relationship between the educational background of the mothers and the perception that uncircumcised girls will be promiscuous. These perceptions about FGM show that government at all levels should continue with educational efforts aimed at eradicating this practice.
Female genital cutting (FGC), a prevalent practice in most African countries not just seriously endangers a girl's lifetime health, but it is also considered a human rights violation. In June 1999, the Intra-Agency Working Group on FGC held a symposium with US Agency for International Development (USAID) staff to explore ways of incorporating into USAID program activities to eradicate the practice of FGC. One of the presentations at the symposium concerned "circumcision with words". This ceremony is an alternative rite of passage; it is conducted through a 5-day seclusion, culminating in a 1-day celebration including feasting and gift giving. The alternative rites include 1) self-esteem and coping with criticism; 2) responsibility for one¿s own decision; 3) dating and courtship; 4) coping with peer pressure; 5) personal hygiene; 6) marriage; 7) pregnancy and sexually transmitted disease and AIDS prevention; 8) contraception; 9) FGC, early marriage, and gender empowerment, including the rights of the girl child; 10) respect for community; and 11) respect for elders. Alternative rites of passage are gaining community acceptance and by Kenya Medical Association. None of the girls who participated in the ceremony were circumcised later.

Despite 30 years of advocacy, the prevalence of non-therapeutic female genital alteration (FGA) in minors is stable in many countries. Educational efforts have minimally changed the prevalence of this procedure in regions where it has been widely practiced. In order to better protect female children from the serious and long-term harms of some types of non-therapeutic FGA, we must adopt a more nuanced position that acknowledges a wide spectrum of procedures that alter female genitalia. We offer a revised categorisation for non-therapeutic FGA that groups procedures by effect and not by process. Acceptance of de minimis procedures that generally do not carry long-term medical risks is culturally sensitive, does not discriminate on the basis of gender, and does not violate human rights. More morbid procedures should not be performed. However, accepting de minimis non-therapeutic f FGA procedures enhances the effort of compassionate practitioners searching for a compromise position that respects cultural differences but protects the health of their patients.

Male genital lichen sclerosus (MGLSc) has a bimodal distribution in boys and men. It is associated with squamous cell carcinoma (SCC). The pathogenesis of MGLSc is unknown. HPV and autoimmune mechanisms have been mooted. Anti extracellular matrix protein (ECM)1 antibodies have been identified in women with GLSc. The gene expression pattern of LSc is unknown. Using DNA microarrays we studied differences in gene expression in healthy and diseased prepuces obtained at circumcision in adult males with MGLSc (n = 4), paediatric LSc (n = 2) and normal healthy paediatric foreskin (n = 4). In adult samples 51 genes with significantly increased expression and 87 genes with significantly reduced expression were identified; paediatric samples revealed 190 genes with significantly increased expression and 148 genes with significantly reduced expression. Concordance of expression profiles between adult and paediatric samples indicates the same disease process. Functional analysis revealed increased expression in the adult and child MGSLc samples in the immune response/cellular defence gene ontology (GO) category and reduced expression in other categories including genes related to squamous cancer. No specific HPV, autoimmune or squamous carcinogenesis-associated gene expression patterns were found. ECM1 and CABLES1 expression were significantly reduced in paediatric and adult samples respectively. PMID:21718371

This case of genital ulceration and social concerns in a preschool aged child was highly suspicious for child sexual abuse. However, the lesions presumed to be herpes simplex did not respond to antiviral medication. Specialist input from paediatric oncology and endocrinology resulted in a rare diagnosis of langerhans cell histiocytosis. Furthermore, the complication of diabetes insipidus later developed, making this the youngest child described to our knowledge with vulval lesions of langerhans cell histiocytosis and a central nervous system complication.

We found that the genitalia of the male cricket Gryllus bimaculatus are equipped with an autocleaning system. The cricket keeps its genitalia clean by removing foreign matter and endogenous waste. Morphological study showed that the membrane complex consists of a median pouch and a genital chamber floor covered by small scales, each of which has a base of approximately 10 µm in width and a fringe with 5-10 spines 3-20 µm in length. The scales are arranged symmetrically about the midline, curving gradually in the lateral direction and continuing to the lateral pouch serving as a trash container. Observation of cleaning revealed that a small piece of artificial dirt placed on the membrane complex was conveyed over a distance of 1.3 mm to the lateral pouch in 12 minutes. Inspection of the dorsal pouch just after spermatophore extrusion in the mating stage revealed that there were patchy remnants of spermatophore material on the inner surface of the pouch, but that these were evacuated in a few minutes. Surgical elimination of the median pouch caused the formation of abnormal spermatophores with the sperm tube and attachment plate being deformed. These results suggest that genital autocleaning is indispensable for the production of a normal spermatophore in the male cricket.

Purpose: To report the success of groin nodal lymphography in the diagnosis and treatment of genital lymphedema. Methods and Materials: We present one female (8 years old [patient no. 1]) and two male (69 and [patient no. 2] 31 years old [patient no. 3], respectively) patients with genital lymphedema in whom conservative treatment failed. The girl also had lymphorrhagia. Genital lymphedema was caused by radical cystectomy (patient no. 2), lymphatic hyperplasia (patient no. 1), and idiopathic lymphangitis (patient no. 3). All of them underwent ultrasound-guided bilateral groin lymph node puncture. Afterward, 4-8 ml Lipiodol Ultra-Fluide (Guerbet) were injected at a rate of 0.2 ml/s. Lipiodol progression was assessed by fluoroscopy. Computed tomography scan of the abdomen and pelvis was performed immediately after and again at 24 h after the procedure to confirm the leak. The follow-up period was 15, 13, and 9 months, respectively. Technical success was considered as bilateral pelvic and abdominal filling of lymphatic vessels. Therapeutic success was considered as improvement or disappearance of genital lymphedema and/or lymphorrhagia. Results: Lipiodol leak to the scrotum was observed in patients no. 2 and 3. Lymphaticopelvic fistula and genital lymphatic hyperplasia were seen in patient no. 1. Genital lymphedema diminished within 1 week and almost disappeared in two cases (patients no. 1 and 3) or significantly improved (patient no. 2). lymphorrhagia also resolved in patient no. 1. No recurrence or worsening was detected during follow-up. Conclusion: Therapeutic lymphangiography by lymph node injection seems to be effective to treat genital lymphedema. Lymph node puncture lymphangiography is feasible and less cumbersome than pedal lymphangiography.

We studied the immunohistological localization of metallothionein (MT), a low molecular weight metal binding protein, in male rat genital organs (testis, epididymis, ejaculatory duct, seminal vesicle, coagulating gland, and prostate) by use of the avidin-biotin-peroxidase complex method. MT concentrations in testis, seminal vesicle, and prostate ranged from 15-30 micrograms/g tissue. In testis, seminiferous tubules with mature spermatozoa exhibited weak MT staining, whereas the tubules containing differentiating spermatogenic cells but not containing spermatozoa showed strong MT staining. No MT immunostaining was observed in Leydig cells. In growing rat testes, the pattern of MT immunostaining was found to change with development: MT was found in supporting cells only on Day 7, spermatogonia adjacent to basement membrane on Day 14, and spermatocytes localized in the central part of the tubules on Day 21. Strong MT immunostaining in the basal cells was a common feature in other genital tissues, except the ductus efferentes. In prostate, the strongest MT staining was found in the lateral lobe, and MT was localized in apocrine secretions in the dorsal lobe. The present results suggest a close association of MT with cell proliferation and differentiation, as well as possible involvement of MT in supply or storage of zinc ions.

As globalization brings people with incompatible attitudes into contact, cultural conflicts inevitably arise. Little is known about how to mitigate conflict and about how the conflicts that occur can shape the cultural evolution of the groups involved. Female genital cutting is a prominent example. Governments and international agencies have promoted the abandonment of cutting for decades, but the practice remains widespread with associated health risks for millions of girls and women. In their efforts to end cutting, international agents have often adopted the view that cutting is locally pervasive and entrenched. This implies the need to introduce values and expectations from outside the local culture. Members of the target society may view such interventions as unwelcome intrusions, and campaigns promoting abandonment have sometimes led to backlash as they struggle to reconcile cultural tolerance with the conviction that cutting violates universal human rights. Cutting, however, is not necessarily locally pervasive and entrenched. We designed experiments on cultural change that exploited the existence of conflicting attitudes within cutting societies. We produced four entertaining movies that served as experimental treatments in two experiments in Sudan, and we developed an implicit association test to unobtrusively measure attitudes about cutting. The movies depart from the view that cutting is locally pervasive by dramatizing members of an extended family as they confront each other with divergent views about whether the family should continue cutting. The movies significantly improved attitudes towards girls who remain uncut, with one in particular having a relatively persistent effect. These results show that using entertainment to dramatize locally discordant views can provide a basis for applied cultural evolution without accentuating intercultural divisions.

The primary goal of treatment for external genital warts (EGWs) is to eradicate visible lesions and address symptoms that may accompany them, but it does not address the underlying virus. Left untreated, warts may grow, remain the same, or spontaneously regress as a result of being cleared by the immune system. However, recurrence is common with or without treatment and may occur within 3 months of ending treatment in one-quarter to two-thirds of cases. Treatment options fall into two categories: provider or patient applied. Provider-based therapies include cryotherapy, trichloroacetic and bichloroacetic acid, electrocautery, surgical excision, and CO2 laser therapy. Patient-applied therapy choices include imiquimod and podophyllotoxin. Imiquimod 3.75% is a fairly new, patient-administered topical cream approved by Health Canada in 2011. Another recently approved patient-applied choice is sinecatechins, a green tea extract with immunomodulatory effects. Self-treatment options are attractive to patients because they offer privacy, convenience, and autonomy. In contrast, provider-administered therapies may boast increased precision (especially for areas that are hard to reach) and closer monitoring, which can be augmented by patient education and counseling. Available topical and surgical therapies vary widely in terms of cost, efficacy, adverse effects, dosage/frequency, and length of treatment. No one treatment is ideally suited to all patients or constitutes a gold standard. Treatment regimens must be tailored to each patient's needs and preferences. The health care provider's skills and experience will also factor into treatment decisions. In addition, the size, number, and location of lesions and whether the infection is new or recurrent will help guide the decision process toward the best treatment for a given patient.

An important question in the study of chlamydial genital tract disease is why some women develop severe upper tract disease while others have mild or even “silent” infections with or without pathology. Animal studies suggest that the pathological outcome of an infection is dependent upon both the composition of the infecting chlamydial population and the genotype of the host, along with host physiological effects, such as the cyclical production of reproductive hormones and even the size of the infecting inoculum or the number of repeated infections. In this study, we compared two variants of Chlamydia caviae, contrasting in virulence, with respect to their abilities to ascend the guinea pig genital tract. We then determined the effect of combining the two variants on the course of infection and on the bacterial loads of the two variants in the genital tract. Although the variants individually had similar infection kinetics in the cervix, SP6, the virulent variant, could be isolated from the oviducts more often and in greater numbers than the attenuated variant, AZ2. SP6 also elicited higher levels of interleukin 8 (IL-8) in the lower genital tract and increased leukocyte infiltration in the cervix and uterus compared to AZ2. When the two variants were combined in a mixed infection, SP6 outcompeted AZ2 in the lower genital tract; however, AZ2 was able to ascend the genital tract as readily as SP6. These data suggest that the ability of SP6 to elicit an inflammatory response in the lower genital tract facilitates the spread of both variants to the oviducts. PMID:26015484

To evaluate any association between female genital cutting and vesicovaginal fistula formation during obstructed labor. A comparison was made between 255 fistula patients who had undergone type I or type II female genital cutting and 237 patients who had not undergone such cutting. Women were operated on at the Barhirdar Hamlin Fistula Centre in Ethiopia. Data points used in the analysis included age; parity; length of labor; labor outcome (stillbirth or not); type of fistula; site, size, and scarring of fistula; outcomes of surgery (fistula closed; persistent incontinence with closed fistula; urinary retention with overflow; site, size, and scarring of any rectovaginal fistula; and operation outcomes), and specific methods used during the operation (use of a graft or not, application of a pubococcygeal or similar autologous sling, vaginoplasty, catheterization of ureters, and flap reconstruction of vagina). Primary outcomes were site of genitourinary fistula and persistent incontinence despite successful fistula closure. The only statistically significant differences between the two groups (P=.05) were a slightly greater need to place ureteral catheters at the time of surgery in women who had not undergone a genital cutting operation, a slightly higher use of a pubococcygeal sling at the time of fistula repair, and a slightly longer length of labor (by 0.3 day) in women who had undergone genital cutting. Type I and type II female genital cutting are not independent causative factors in the development of obstetric fistulae from obstructed labor.

Data points used in the analysis included age, parity, length of labor, labor outcome (stillbirth or not), type of fistula, site, size and scarring of fistula, outcomes of surgery (fistula closed, persistent incontinence with closed fistula, urinary retention with overflow, site, size, and scarring of any rectovaginal fistula and operation outcomes, as well as specific methods employed during the operation (utilization of a graft or not, application of a pubococcygeal or similar autologous sling, vaginoplasty, catheterization of ureters, and flap reconstruction of vagina). Primary outcomes were site of genitourinary fistula and persistent incontinence despite successful fistula closure. Results The only statistically significant differences between the two groups (p = 0.05) was a slightly greater need to place ureteral catheters at the time of surgery in women who had not undergone a genital cutting operation, and slightly higher use of a pubococcygeal sling at the time of fistula repair and a slightly longer length of labor (by 0.3 of a day) in women who had undergone genital cutting. Conclusion Type I and Type II female genital cutting are not independent causative factors in the development of obstetric fistulas from obstructed labor. PMID:20177289

Objectives Genital ulcer disease (GUD) prevalence increases in the first month of antiretroviral treatment (ART), followed by a return to baseline prevalence by month 3. Since most GUD is caused by herpes simplex virus type 2 (HSV-2), we hypothesized that genital HSV detection would follow a similar pattern after treatment initiation. Methods We conducted a prospective cohort study of 122 HSV-2 and HIV-1 co-infected women with advanced HIV disease who initiated ART and were followed closely with collection of genital swab specimens for the first three months of treatment. Results At baseline, the HSV detection rate was 32%, without significant increase in genital HSV detection noted during the first month or the third month of ART. HIV-1 shedding declined during this period; no association was also noted between HSV and HIV-1 shedding during this period. Conclusion Because other studies have reported increased HSV detection in women initiating ART and we have previously reported an increase in GUD during early ART, it may be prudent to counsel HIV-1 infected women initiating ART that HSV shedding in the genital tract may continue after ART initiation.

Objectives To determine if healthy, young women in sub-Saharan Africa have a more activated immune milieu in the genital tract (i.e. activated CD4+ T-cells) than a similar population in the US. Design Cross-sectional study nested in a phase 1 microbicide trial. Methods Cervical cytobrushes were collected from 18–24 year old women in San Francisco, CA (n=18) and Kisumu, Kenya (n=36) at enrollment into a phase 1 microbicide trial. All participants tested negative for HIV, HSV-2, gonorrhea, chlamydia and trichomonas, and had abstained from sex for at least seven days prior to enrollment. Cryopreserved T-cell populations were assayed by flow cytometry in a central laboratory. SLPI levels were assayed in cervicovaginal lavage samples. The Wilcoxon rank-sum test was used to compare immune parameters between sites. Results The total number of endocervical CD4+ T-cells was slightly higher in San Francisco, but participants from Kisumu had a substantially higher number and proportion of CD4+ T-cells expressing the early activation marker CD69, with and without the HIV-coreceptor CCR5, and a greater proportion of activated CD8+ T-cells. Median [interquartile] genital levels of SLPI were lower in participants from Kisumu compared to those from San Francisco (190 pg/mL [96, 519] vs. 474 pg/mL [206, 817]; p<0.03). Conclusions Activated mucosal T-cells were increased in the genital tract of young, STI/HIV-free Kenyan women, independent of common genital co-infections, and SLPI levels were reduced. The cause of these mucosal immune differences is not known, but could partly explain the high HIV incidence in young women from sub-Saharan Africa. PMID:20588163

Cutaneous human papillomaviruses (HPVs) may be associated with cutaneous epithelial lesions and non-melanoma skin cancers. No study has systematically evaluated the presence of genus beta [β]-HPV in male genital skin or external genital lesions (EGLs) To examine cutaneous β-HPV types detected on the surface of EGLs in men and describe their presence prior to EGL development. A retrospective case series was conducted among 69 men with pathologically confirmed EGLs (n=72) who participated in the HPV Infection in Men Study. Archived exfoliated cells collected from the surface of each EGL and normal genital skin specimens 6-12 months preceding EGL development were tested for β-HPV DNA using a type-specific multiplex genotyping assay. β-HPV DNA was detected on 61.1% of all EGLs, with types 38 (16.7%), 5 (15.3%), and 12 (12.5%) most commonly identified. HPV prevalence differed across pathological diagnoses, with the largest number of β-HPV types detected on condylomas. Most β-HPV types were detected on normal genital skin prior to EGL development, though the prevalence was lower on EGLs compared to preceding normal genital skin. EGLs and the normal genital skin of men harbor a large number of β-HPV types; however, it appears that β-HPVs are unrelated to EGL development in men. Despite evidence to support a causal role in skin carcinogenesis at UVR-exposed sites, cutaneous HPV appears unlikely to cause disease at the UVR-unexposed genitals. Copyright © 2013 Elsevier B.V.

Genital powder use has been associated with risk of epithelial ovarian cancer in some, but not all, epidemiologic investigations, possibly reflecting the carcinogenic effects of talc particles found in most of these products. Whether risk increases with number of genital powder applications and for all histologic types of ovarian cancer also remains uncertain. Therefore, we estimated the association between self-reported genital powder use and epithelial ovarian cancer risk in eight population-based case-control studies. Individual data from each study were collected and harmonized. Lifetime number of genital powder applications was estimated from duration and frequency of use. Pooled ORs were calculated using conditional logistic regression matched on study and age and adjusted for potential confounders. Subtype-specific risks were estimated according to tumor behavior and histology. 8,525 cases and 9,859 controls were included in the analyses. Genital powder use was associated with a modest increased risk of epithelial ovarian cancer [OR, 1.24; 95% confidence interval (CI), 1.15-1.33] relative to women who never used powder. Risk was elevated for invasive serous (OR, 1.20; 95% CI, 1.09-1.32), endometrioid (OR, 1.22; 95% CI, 1.04-1.43), and clear cell (OR, 1.24; 95% CI, 1.01-1.52) tumors, and for borderline serous tumors (OR, 1.46; 95% CI, 1.24-1.72). Among genital powder users, we observed no significant trend (P = 0.17) in risk with increasing number of lifetime applications (assessed in quartiles). We noted no increase in risk among women who only reported nongenital powder use. In summary, genital powder use is a modifiable exposure associated with small-to-moderate increases in risk of most histologic subtypes of epithelial ovarian cancer.

Findings regarding the link between body image and sexuality have been equivocal, possibly because of the insensitivity of many of body image measures to potential variability across sensory aspects of the body (e.g., appearance versus odor), individual body parts (e.g., genitalia versus thighs), and social settings (e.g., public versus intimate). The current study refined existing methods of evaluating women’s body image in the context of sexuality by focusing upon two highly specified dimensions: satisfaction with the visual appearance of the genitalia and self-consciousness about the genitalia during a sexual encounter. Genital appearance dissatisfaction, genital image self-consciousness, and multiple facets of sexuality were examined with a sample of 217 undergraduate women using an online survey. Path analysis revealed that greater dissatisfaction with genital appearance was associated with higher genital image self-consciousness during physical intimacy, which, in turn, was associated with lower sexual esteem, sexual satisfaction, and motivation to avoid risky sexual behavior. These findings underscore the detrimental impact of negative genital perceptions on young women’s sexual wellbeing, which is of particular concern given their vulnerability at this stage of sexual development as well as the high rates of sexually transmitted infections within this age group. Interventions that enhance satisfaction with the natural appearance of their genitalia could facilitate the development of a healthy sexual self-concept and provide long-term benefits in terms of sexual safety and satisfaction.

This cross-sectional survey explored the frequency of genital herpes testing among 110 people living with HIV (PLWH) and reported barriers and facilitators related to testing. Forty-four percent of the respondents had not been tested for genital herpes since receiving an HIV diagnosis, 34% had been tested, and 22% preferred not to say. Respondents' most frequently cited factors affecting a decision to not be tested were: (a) testing not being recommended by a provider, (b) not having herpes symptoms, and (c) not thinking they had herpes. Data from this study indicated that PLWH were not frequently tested for genital herpes; there was a limited understanding of the frequently subclinical nature of infection; and provider recommendations for testing, or lack thereof, affected testing decisions.

The epidemiology of oral and genital herpes has dramatically changed over the past decade. Herpes simplex virus-1, traditionally associated with oral herpes, is now implicated in an increasing percentage of genital herpes cases. The possibility of "autoinoculation" (or self-infection) of anatomic sites other than that of the primary infection has been recognized. New methods of suppression therapy are being examined. These changes have led to a revision in the recommendations by the Centers for Disease Control and Prevention (CDC). This review discusses herpes infections of the oral and genital mucosa and the suggested approach to the infected patient who presents in the emergency department. Specific attention is given to the CDC's 2006 guidelines for the treatment of sexually transmitted diseases.

Mucosal immunity consists of innate and adaptive immune responses which can be influenced by systemic immunity. Despite having been the subject of intensive studies, it is not fully elucidated what exactly occurs after HIV contact with the female genital tract mucosa. The sexual route is the main route of HIV transmission, with an increased risk of infection in women compared to men. Several characteristics of the female genital tract make it suitable for inoculation, establishment of infection, and systemic spread of the virus, which causes local changes that may favor the development of infections by other pathogens, often called sexually transmitted diseases (STDs). The relationship of these STDs with HIV infection has been widely studied. Here we review the characteristics of mucosal immunity of the female genital tract, its alterations due to HIV/AIDS, and the characteristics of coinfections between HIV/AIDS and the most prevalent STDs.

To relate the Female Genital Mutilation as a negative factor for the achievement of the Millennium Development Goals 1, 3, 4, 5 and 6. Data collection was through review literature review between in the years 2014 and 2015 in the databases Medline/PubMed, Web of Science, LILACS, SCIELO, Tesis Doctorales TESEO and in the webs of WOK, UNICEF, UNAF and WHO using the descriptors: female circumcision, millennium development goals, rights of women. Articles published between years 2010 y 2015, were included and finally 24 articles were selected. The Female Genital Mutilation is based on gender discrimination, and reinforces and encourages the circle of poverty. This practice causes physical complications that may affect the infant mortality and morbidity, complications in pregnancy and childbirth and there is a relationship between the practice and the transmission of human immunodeficiency virus. The fight against Female Genital Mutilation contributes to the achievement of five of the eight Millennium Goals.
Sexual abuse is a problem of epidemic proportions in the United States. Pediatric nurse practitioners (PNPs) are at the forefront of providing care to children and families. The PNP is in a unique position to educate patients and families regarding sexual abuse and dispel common myths associated with sexual abuse. One such myth is that a normal ano-genital examination is synonymous with the absence of sexual abuse. This article will provide primary care providers, including PNPs, with a framework for understanding why a normal ano-genital examination does not negate the possibility of sexual abuse/assault. Normal ano-genital anatomy, changes that occur with puberty, and physical properties related to the genitalia and anus will be discussed. Photos will provide visualization of both normal variants of the pre-pubertal hymen and genitalia as well as changes that occur with puberty. Implications for practice for PNPs will be discussed.
Female genital mutilation is the medically unnecessary modification of female genitalia. Female genital mutilation typically occurs at about 7 years of age, but mutilated women suffer severe medical complications throughout their adult lives. Female genital mutilation most frequently occurs in Africa, the Middle East, and Muslim parts of Indonesia and Malaysia, and it is generally part of a ceremonial induction into adult society. Recent political and economic problems in these regions, however, have increased the numbers of students and refugees to the United States. Consequently, US physicians are treating an increasing number of mutilated patients. The Council on Scientific Affairs recommends that US physicians join the World Health Organization, the World Medical Association, and other major health care organizations in opposing all forms of medically unnecessary surgical modification of the female genitalia.

The male genital tract plays an important role in protecting sperm by forming a distinct compartment separate from the body which limits exposure to potentially toxic substrates. Transporters along this tract can influence the distribution of xenobiotics into the male genital tract through efflux back into the blood or facilitating the accumulation of toxicants. The aim of this study was to quantitatively determine the constitutive mRNA expression of 30 xenobiotic transporters in caput and cauda regions of the epididymis, vas deferens, prostate, and seminal vesicles from adult Sprague-Dawley rats. The epididymis was found to express at least moderate levels of 18 transporters, vas deferens 15, seminal vesicles 23, and prostate 18. Constitutive expression of these xenobiotic transporters in the male genital tract may provide insight into the xenobiotics that can potentially be transported into these tissues and may provide the molecular mechanism for site specific toxicity of select agents.

Objective: Our objective was to determine the role of Mycoplasma hominis and Ureaplasma urealyticum in pelvic inflammatory disease (PID). Methods: The clinical and microbiologic variables in 114 patients with a clinical diagnosis of PID were compared prospectively according to the isolation of M. hominis and U. urealyticum from their endometrial cavities. Results: The groups were epidemiologically well matched. Clinical parameters such as temperature, leukocyte count, erythrocyte count, and C-reactive protein on admission and length of hospital stay were similar in the patients, regardless of their mycoplasma status. A significant percentage of the patients either continued or started to harbor genital mycoplasmas after the resolution of PID without any significant clinical sequelae. Conclusions: The presence of genital mycoplasmas does not change the clinical presentation and course of PID. Both M. hominis and U. urealyticum can persist or colonize the endometrium after complete recovery from PID. Therefore, the genital mycoplasmas do not seem to have a dominant pathogenic role in PID.

Genital tuberculosis (TB) is an important cause of female infertility in the world, especially in developing countries. Majority of infertility cases are due to involvement of the fallopian tubes (92%-100%), endometrial cavity (50%), and ovaries (10%-30%); cervical and vulvovaginal TB are uncommon. Genital TB has characteristic radiological appearances based on the stage of the disease process (acute inflammatory or chronic fibrotic) and the organ of involvement. Hysterosalpingography (HSG) and ultrasonography (US) remain the main imaging modalities used in the diagnosis of genital TB. HSG is the primary modality for evaluating uterine, fallopian tube, and peritubal involvement and also helps in evaluating tubal patency. US, on the other hand, allows simultaneous evaluation of ovarian and extrapelvic involvement.

Douching has been linked to gonococcal or chlamydial cervicitis and pelvic inflammatory disease (PID) in retrospective studies. The authors conducted a 1999-2004 prospective observational study of 1,199 US women who were at high risk of acquiring chlamydia and were followed for up to 4 years. Cervical Neisseria gonorrhoeae and Chlamydia trachomatis were detected from vaginal swabs by nucleic acid amplification. PID was characterized by histologic endometritis or pelvic pain and tenderness plus one of the following: oral temperature >38.3 degrees C, leukorrhea or mucopus, erythrocyte sedimentation rate >15 mm/hour, white blood cell count >10,000, or gonococcal/chlamydial lower genital tract infection. Associations between douching and PID or gonococcal/chlamydial genital infections were assessed by proportional hazards models. The 4-year incidence rate of PID was 10.9% and of gonococcal and/or chlamydial cervicitis was 21.9%. After adjustment for confounding factors, douching two or more times per month at baseline was associated with neither PID (adjusted hazard ratio = 0.76, 95% confidence interval: 0.42, 1.38) nor gonococcal/chlamydial genital infection (adjusted hazard ratio = 1.16, 95% confidence interval: 0.76, 1.78). Frequency of douching immediately preceding PID or gonococcal/chlamydial genital infection was not different between women who developed versus did not develop outcomes. These data do not support an association between douching and development of PID or gonococcal/chlamydial genital infection among predominantly young, African-American women.

The recently failed clinical efficacy trial of an acquired immunodeficiency syndrome (AIDS) vaccine that elicits antiviral CD8(+) T-cell responses has emphasized the challenge of producing an effective vaccine against human immunodeficiency virus (HIV). In the simian immunodeficiency virus (SIV)/ rhesus monkey model of AIDS, live-attenuated lentivirus 'vaccines' provide the best protection from uncontrolled viral replication and clinical disease after pathogenic SIV challenge. This review summarizes a recent series of studies in which we show that after vaginal SIV challenge of rhesus macaques immunized with an attenuated lentivirus protection from uncontrolled viral replication is primarily mediated by CD8(+) T cells in the vaginal mucosa. Immunization with a chimeric simian/human immunodeficiency virus (SHIV) results in a systemic infection that induces a moderate population of SIV-specific CD8(+) and CD4(+) T cells with cytolytic potential in the vaginal mucosa. Depletion of CD8(+) T cells at the time of SIV challenge completely abrogates the protection mediated by prior infection with attenuated SHIV. Further after vaginal SIV challenge, the only significant expansion of SIV-specific T cells occurs in the vagina in these animals. No significant expansion of T-cell responses was observed in systemic lymphoid tissues. Thus, the presence of SIV-specific CD8(+) T cells in the vagina on the day of vaginal SIV challenge and a modest expansion of local effector T cells is sufficient to stop uncontrolled SIV replication. It seems that T-cell based vaccine strategies that can elicit mucosal effector CD8(+) T-cell populations and avoid inducing systemic T-cell proliferation upon exposure to HIV have the greatest potential for mimicking the success of live-attenuated lentiviral vaccines.

The high prevalence of female genital mutilation has been a concern in Iraqi Kurdistan. This study was undertaken to estimate its prevalence and describe factors associated with its occurrence. A cross-sectional survey was undertaken from March to April 2011 of females aged up to 20 years using interviews and clinical examination. The survey included 1,508 participants with mean age of 13.5 years (SD 5.6). Overall female genital mutilation prevalence was 23%, and the mean age at which it had been performed was 4.6 years (SD 2.4). Type I (partial or total removal of the clitoris) comprised 76% of those who had had female genital mutilation; in 79% of cases the decision to perform it was made by the mother; and in 54% of cases it was performed by traditional birth attendants/midwives. Women aged 16 years and over were more likely to have had female genital mutilation compared to children aged below 6 years (OR 11.9, p < .001). Children of uneducated mothers were eight times as likely to have had genital mutilation compared to children of mothers with over nine years of education (OR 8.0, p < .001). Among women aged 17 years and younger, 34% of those who were married had been circumcised versus 17% of those who were not married (p < .001). Participants residing in the northeast of Kurdistan region were more likely to have been circumcised. The study results show that female genital mutilation is a frequent practice in Iraqi Kurdistan. Attention and intervention is needed to address this aspect of the well-being of girls and women.

OBJECTIVE: To describe the recent epidemiology of genital Chlamydia trachomatis infection in England and Wales. DESIGN: Retrospective study of routinely available surveillance datasets and ad hoc prevalence studies. METHODS: Numbers of new cases of genital C trachomatis infection, obtained from the Department of Health and Welsh Office, were combined with the estimated mid-year resident population of England and Wales. Rates were analysed for trend over time using a log linear age period model in GLIM4. Ad hoc prevalence and case finding studies carried out over the past 20 years were critically assessed in terms of study design and testing methodologies. RESULTS: Attendance rates at genitourinary medicine (GUM) clinics were higher for women than men over the period 1989 to 1994 as were the number of laboratory reports. The highest rate of attendance (GUM clinic data) was for women aged 16 to 19 years. There was an overall significant linear decrease in the attendance rates over time for both men (p = 0.0172) and women (p = 0.0000) between 1989 and 1994. There was considerable variation in the prevalence of genital C trachomatis infection detected within different clinical settings, together with a substantial level of asymptomatic infection. CONCLUSIONS: Genital C trachomatis infection is broadly distributed throughout the sexually active population, with a substantial reservoir of asymptomatic infection among those generally perceived to be at low risk of a sexually transmitted infection. Young people, particularly women aged 16 to 19 years, are at highest risk of genital C trachomatis infection. This is of concern since younger women are more susceptible than older women to developing complications of chlamydial infection, such as pelvic inflammatory disease. The broad distribution of infection across all sexually active health service attenders and the high level of asymptomatic infection suggest that a new, screening based, approach to the control of genital C

Based on a survey of 467 men with genital tuberculosis, following conclusions were made. The presence of morphological signs of nonspecific prostatitis of toxic-allergic genesis in patients with newly diagnosed tuberculosis of the urinary and genital organs proves the possibility of primary infection of the epididymis with Mycobacterium tuberculosis. Primarily isolated epididymal tuberculosis was diagnosed in 21 (4,5%) patients. Tuberculous of testicles is in direct relationship to the duration of the existence of tuberculous infection in the epididymis. Bilateral tuberculous of the epididymis is always combined with tuberculosis of the prostate. Opportunity of both primary and secondary infection of the prostate gland with Mycobacterium tuberculosis can be considered as proved. 15 (3,2%) patients had initially isolated prostatic tuberculosis. Based on clinical observations, exogenous way of introduction of infection in tuberculosis of genital organs in men was not confirmed. The lymphogenous and hematogenous pathways are leading and most common pathways of Mycobacterium tuberculosis in the male genitals. In patients with tuberculosis of the prostate, which is combined with a lesion of urinary organs, without involvement of scrotum in the pathological process, infection of prostate occurs by urinogenous way. Tuberculosis of the seminal vesicles is always secondary; none of the patients were initially diagnosed with isolated process. Based on the clinical manifestations of the disease and a detailed examination of the patient, it is virtually impossible to establish a particular way of infection in the male genitals. The main value of the information about the possible ways of tuberculosis infection consists of fully examination of reproductive system with histological and bacteriological verification of the diagnosis of each genital organs in each man with suspected tuberculosis.

Disclosure is often a challenge for individuals living with genital herpes. This study explores determinants of genital herpes disclosure with one's most recent sexual partner using an online questionnaire (n = 93). The majority of participants reported (80.4%) disclosure. Among non-disclosers, fear of negative partner reactions was the primary reason for non-disclosure. Age, relationship commitment, time in relationship, and expectations of partner's reaction were statistically significant predictors at the bivariate level. Reaction expectations and relationship commitment remained significant in the multivariate logistic regression model. Findings indicate that future disclosure research should focus on relationship context and managing negative expectations to increase disclosure.

Genital ulcerations are a rare clinical finding of Epstein-Barr virus (EBV) infection. We present the case of a 16-year-old adolescent girl who reported the onset of diarrhea, headaches, dysuria, and vaginal discharge along with vulvar ulcerations with edema. Laboratory studies revealed a high-quantitative EBV IgG and early antigen as well as a positive IgM antibody for EBV. Although the association between EBV and genital ulcerations is rare, physicians should be aware of this clinical presentation to exclude other infectious entities, to be reassured to accept negative testing, and to quell patient distress or concerns of abuse.

Extensive research and field work have established that more than 74 million women and female children are mutilated by female genital operations in Africa alone. The operations are also practiced in many parts of the Middle East and, with Moslemization, were introduced into Indonesia and Malaysia where they are preformed at the present time in a less damaging form. This paper lists the countries where instances of excision and infibulation have been reported and includes case reports from Sudan, Egypt, Ethiopia, Kenya, Somalia, Nigeria, Mali, Upper Volta, and Senegal. The ethical issues posed by genital mutilation are also discussed.

Lipschütz ulcers are characterised by a first flare of non-sexually related acute genital ulcers (AGU) occurring in adolescent girls. Epstein-Barr primary infection is the most frequently reported aetiology but other infectious agents are probably implicated. We report the first case of mumps associated with an AGU in a 21-year-old girl. She presented a bilateral parotitis with genital ulcers, and serology confirmed she had mumps. As in our case, most Lipschütz ulcers heal spontaneously within a couple of weeks and the diagnosis should be reconsidered in case of recurrence. Copyright © 2010 S. Karger AG, Basel.

The pharmacokinetics (PK) of tenofovir-diphosphate (TFV-DP) and emtricitabine-triphosphate (FTC-TP), the active anabolites of tenofovir disoproxil fumarate (TDF), and emtricitabine (FTC) in blood, genital, and rectal compartments was determined in HIV-positive and seronegative adults who undertook a 60-day intensive PK study of daily TDF/FTC (plus efavirenz in HIV positives). Lymphocyte cell sorting, genital, and rectal sampling occurred once per subject, at staggered visits. Among 19 HIV-positive (3 female) and 21 seronegative (10 female) adults, TFV-DP in peripheral blood mononuclear cells (PBMC) accumulated 8.6-fold [95% confidence interval (CI): 7.2-10] from first-dose to steady-state concentration (Css) versus 1.7-fold (95% CI: 1.5-1.9) for FTC-TP. Css was reached in ∼11 and 3 days, respectively. Css values were similar between HIV-negative and HIV-positive individuals. Css TFV-DP in rectal mononuclear cells (1,450 fmol/10(6) cells, 898-2,340) was achieved in 5 days and was >10 times higher than PBMC (95 fmol/10(6) cells, 85-106), seminal cells (22 fmol/10(6) cells, 6-79), and cervical cells (111 fmol/10(6) cells, 64-194). FTC-TP Css was highest in PBMC (5.7 pmol/10(6) cells, 5.2-6.1) and cervical cells (7 pmol/10(6) cells, 2-19) versus rectal (0.8 pmol/10(6) cells, 0.6-1.1) and seminal cells (0.3 pmol/10(6) cells, 0.2-0.5). Genital drug concentrations on days 1-7 overlapped with estimated Css, but accumulation characteristics were based on limited data. TFV-DP and FTC-TP in cell sorted samples were highest and achieved most rapidly in CD14(+) compared with CD4(+), CD8(+), and CD19(+) cells. Together, these findings demonstrate cell-type and tissue-dependent cellular pharmacology, preferential accumulation of TFV-DP in rectal mononuclear cells, and rapid distribution into rectal and genital compartments.

We conducted a literature review of patients' conditions described under persistent genital arousal disorder and restless genital syndrome, vulvodynia and male genital skin pain of unknown aetiology (penoscrotodynia). Our aim is to improve the understanding of the condition, unify nomenclature and promote evidence-based practice. The most prominent symptom in persistent genital arousal disorder and restless genital syndrome is a spontaneous, unwelcomed, intrusive and distressing vulval sensation. There are similarities between the clinical presentation of vulvodynia, penoscrotodynia, persistent genital arousal disorder and restless genital syndrome patients. The aetiology of persistent genital arousal disorder and restless genital syndrome, similar to vulvodynia, could be better explained in terms of neuro-vascular dysfunction, genital peripheral neuropathy and/or dysfunctional micro-vascular arterio-venous shunting. Erythromelalgia lends itself to explain some cases of restless genital syndrome, who have concurrent restless legs syndrome; and therefore draw parallels with the red scrotum syndrome. The published literature supports the concept of classifying restless genital syndrome as a sub-type of vulvodynia rather than sexual dysfunction.

Nontherapeutic female genital modifications can cause short- and long-term consequences. Caregivers should promote women's self knowledge on genitals' anatomy and physiology, and psychophysical and sexual health. They should also inform on possible negative consequences of vulvar nontherapeutic alterations requested and avoid the medicalization of female genital mutilation.

Genital diversity may arise through sexual conflict over polyandry, where male genital features function to manipulate female mating frequency against her interest. Correlated genital evolution across animal groups is consistent with this view, but a link between genital complexity and mating rates remains to be established. In sexually size dimorphic spiders, golden orbweaving spiders (Nephilidae) males mutilate their genitals to form genital plugs, but these plugs do not always prevent female polyandry. In a comparative framework, we test whether male and female genital complexity coevolve, and how these morphologies, as well as sexual cannibalism, relate to the evolution of mating systems. Using a combination of comparative tests, we show that male genital complexity negatively correlates with female mating rates, and that levels of sexual cannibalism negatively correlate with male mating rates. We also confirm a positive correlation between male and female genital complexity. The macroevolutionary trajectory is consistent with a repeated evolution from polyandry to monandry coinciding with the evolution towards more complex male genitals. These results are consistent with the predictions from sexual conflict theory, although sexual conflict may not be the only mechanism responsible for the evolution of genital complexity and mating systems. Nevertheless, our comparative evidence suggests that in golden orbweavers, male genital complexity limits female mating rates, and sexual cannibalism by females coincides with monogyny.

Genitalia are rapidly evolving morphological structures most likely under sexual selection. Due to their internal nature they are often hidden inside the body, thus morpho-functional studies of animal genitalia are broadly lacking. Males of some bushcricket taxa bear paired genital appendices called titillators, the exact function of which is unknown since they are obscured inside the female body during pairing. To investigate titillator morphology and possible function during copulation, we studied the bushcricket Metrioptera roeselii (Hagenbach, 1822) using a novel combination of independent, yet complementary, techniques. Copulating pairs were snap-frozen and scanned by X-ray micro-computed tomography (μCT) to visualize the coupling of male and female genitalia in situ. Video recordings of copulating pairs also showed rhythmical insertion of male titillators into the female's genital chamber, where they percuss a softened structure on the female's subgenital plate. Movements did not induce damage to the female's structure, which lacks any sclerotized genital counterparts. Instead, scanning electron microscopy and histological sections show the female subgenital plate to be covered with two different types of sensory receptors at the contact zone between the male's titillator and the female genital chamber. We interpret the non-harmful function of the titillator processes, the lack of a genital counter-structure and the presence of sensory cells on the female's subgenital plate as indicators of a copulatory courtship function of titillators, subject to sexual selection by female choice.

Herpes simplex virus types 1 (HSV-1) and 2 (HSV-2) cause genital herpes, which can enhance the acquisition of human immunodeficiency virus. The development of anti-HSV agents with novel mechanisms of action is urgently required in the topical therapy of genital herpes. In this study, the in vitro and in vivo anti-HSV effects of Epomin SP-012(®), a highly cationic polyethylenimine, were evaluated. When the in vitro antiviral effects of SP-012 were assessed, this compound showed potent activity against HSV-1 and HSV-2. It inhibited the attachment of HSV-2 to host cells and cell-to-cell spread of infection in a concentration-dependent manner and exerted a virucidal effect. No SP-012-resistant HSV-2 was found when the virus was successively passaged in the presence of SP-012. In a mouse genital herpes model, topically administered SP-012 inhibited the progression of the disease caused by HSV infection. These data illustrate that SP-012 may be a novel class of HSV inhibitor that would be acceptable for long-term topical application.

Background: Tuberculosis (TB) is an increasing public health concern worldwide. On a global scale it has a devastating impact in developing nations. Genital TB, an extrapulmonary form, is not uncommon particularly in areas where pulmonary TB is prevalent. Genital TB may be asymptomatic or may even masquerade as other gynaecological conditions; hence, diagnosis requires a high degree of suspicion and the use of appropriate investigations. Objective: This study attempted to identify endometrial TB in endometrial biopsies taken from women evaluated for infertility by comparison of various staining techniques. Materials and Methods: A comparative cross sectional study was conducted from February 2011 to April 2011 in Guru Teg Bahadur Hospital, New Delhi. Endometrial biopsy specimens from 55 endometrial TB suspects were stained for acid fast bacilli by Ziehl Neelson staining and Gabbet staining. The biopsy samples were also subjected to Auramine Phenol fluroscent staining and H and E staining. Culture on Lowenstein Jensen medium was taken as the gold standard. Results: Three samples were culture positive giving positivity rate of 5.4%. Considering culture as the gold standard the senstivities of ZN, Gabbet, fluorescent and H and E staining were 33, 33, 66, and 66% respectively while their specificities were 100, 100, 98, and100% respectively. Conclusion: Combination of fluorescent staining techniques along with one of the acid fast staining techniques or histopathology achieves sufficient sensitivity and specificity for the diagnosis of female genital tuberculosis. There is an urgent need for developing definitive diagnostic methods to make a conclusive diagnosis of genital TB. PMID:24639789

Vaginal ulcers can be associated with a number of different diseases. We describe two girls who presented genital ulcers as a persistent symptom of PFAPA (periodic fever, aphthous stomatitis, pharyngitis, cervical adenitis) syndrome. The possibility of considering this clinical manifestation as a clue for the diagnosis of PFAPA is discussed.

Although the genital tract is considered to be a component of the mucosal immune system, it displays several distinct features not shared by other typical mucosal tissues and external secretions. Both male and female genital tract tissues lack inductive mucosal sites analogous to intestinal Peyer's patches. Consequently, local humoral and cellular immune responses stimulated by infections [with e.g. Neisseria gonorrhoeae, Chlamydia trachomatis, papilloma virus, and human immunodeficiency virus (HIV-1)] are weak or absent, and repeated local intravaginal immunizations result in minimal humoral responses. In contrast to typical external secretions such as intestinal fluid that contain secretory immunoglobulin A (S-IgA) as the dominant isotype, semen and cervico-vaginal fluid contain more IgG than IgA. Furthermore, irrespective of the route of infection, humoral immune responses to HIV-1 are dominated by specific IgG and low or absent IgA antibodies in all external secretions. Because a significant proportion of IgG in genital tract secretions is derived from the circulation, systemic immunization may provide protective IgG antibody-mediated immunity in the genital tract. Furthermore, combined systemic and mucosal (oral, rectal, and especially intranasal) immunization may induce protective humoral responses in both the systemic and mucosal compartments of the immune system.

The objective was to determine the contribution of female genital cutting to genital fistula formation in Niger from the case records of a specialist fistula hospital. A retrospective review was undertaken of the records of 360 patients seen at the Danja Fistula Center, Danja, Niger, between March 2014 and September 2016. Pertinent clinical and socio-demographic data were abstracted from the cases identified. A total of 10 fistulas resulting from gurya cutting was obtained: 9 cases of urethral loss and 1 rectovaginal fistula. In none of the cases was genital cutting performed for obstructed labor or as part of ritual coming-of-age ceremonies, but all cutting procedures were considered "therapeutic" within the local cultural context as treatment for dyspareunia, lack of interest in or unwillingness to engage in sexual intercourse, or female behavior that was deemed to be culturally inappropriate by the male spouse, parents, or in-laws. Clinical cure (fistula closed and the patient continent) was obtained in all 10 cases, although 3 women required more than one operation. Gurya cutting is an uncommon, but preventable, cause of genital fistulas in Niger. The socio-cultural context which gives rise to gurya cutting is explored in some detail.

To determine the clinical utility of transvaginal sonography for the diagnosis of upper genital tract infection. Fifty-five women who either met the Centers for Disease Control and Prevention's minimal criteria for acute pelvic inflammatory disease or were being seen for non-classic signs of upper genital tract infection were evaluated. During abdominal and endovaginal ultrasound testing, fluid in the cul-de-sac, discrete tubes with or without tubal fluid, multicystic ovaries, and adnexal masses were noted. Upper genital tract infection was confirmed by laparoscopic visualization or histologic or microbiologic evidence of salpingitis of endometritis. The specificity of identifying fallopian tubes with or without intraluminal fluid on ultrasound was 97% (35 of 36); the sensitivity, however, was only 32% (six of 19). Calculated using Bayes theorem and based on a prevalence rate of 50%, the positive predictive value of visualizing fallopian tubes was 91%. The sensitivities associated with the visualization of a multicystic ovary or tubo-ovarian abscess were 42% (eight of 19) and 32% (six of 19), with specificities of 86% (31 of 36) and 97%, (35 of 36), and positive predictive values of 75% and 91%, respectively. Cul-de-sac fluid was associated with low sensitivity (37%; seven of 19), low specificity (58%; 21 of 36), and the lowest positive predictive value (47%). Endovaginal sonography has limited clinical utility in the diagnosis of upper genital tract infection due to its low sensitivity.

First HSV-1 genital episodes in HSV-2 infected patients however, had never been demonstrated until the 2 cases we observed. This scarcity could reflect the lower impact of HSV-2 on western populations but questions the existence of cross-protection between viral types.

The highly masculinized genitalia of female spotted hyenas Crocuta crocuta is unique among mammals: Crocuta have no external vagina so urination, penile intromission and parturition take place through the clitoris, which mimics a fully erectile male penis. Among hyenids, virilization of external female genitalia has previously been observed only in Crocuta, so functional explanations of masculinization have focused on aspects of social ecology unique to the species. Here we first show that the striped hyena Hyaena hyaena exhibits both unusual similarity in male and female androgen concentrations and transient genital anomalies characterized by a convergence in genital appearance among young males and females. We then evaluate hypotheses regarding the evolution of genital masculinization in the Hyaenidae and other taxa. Hyaena are behaviorally solitary, so discovery of unusual genital development patterns in this species does not support any current evolutionary models for masculinization in Crocuta, which all rely on the trait originating within a highly social species. Some hypotheses can be modified so that masculinization in Crocuta represents an extreme elaboration of a preexisting trait, shared as a homology with Hyaena.

To assess the prevalence of genital Mycoplasma spp. among women with systemic lupus erythematosus (SLE) and to identify factors associated with such infection. A cross-sectional study was conducted among patients with SLE and healthy women who attended a hospital in Puebla, Mexico, between July 29, 2014, and January 4, 2015. All participants were aged 18 years or older and sexually active. A structured interview assessed sociodemographic, obstetric, gynecologic, and clinical characteristics. Disease activity was evaluated using the Mexican SLE Disease Activity Index. Polymerase chain reaction was used to detect the presence of Mycoplasma spp. in genital samples. Ureaplasma urealyticum was the only genital mycoplasma detected; it was present in 32 (24.6%) of 130 patients with SLE and 12 (12.8%) of 94 healthy women. Patients with SLE had increased odds of infection (odds ratio 2.120, 95% confidence interval 1.046-4.296). Among patients with SLE, multiparity was more common in those with U. urealyticum infection (P=0.043). One-quarter of women with SLE had genital infection with U. urealyticum. An association was found between infection and multiparity among women with SLE. © 2017 International Federation of Gynecology and Obstetrics.

The purpose of genital examination (GE) during the Pre-participation Physical Examination (PPE) is to identify the state of maturity, and rule out any genital pathology. To describe genital anomalies (GA) and estimate the awareness of GE in young football players. A descriptive, cross-sectional study was conducted in 280 elite football players from the results of PPE over two seasons. There was a detection rate of 5.4% GA, with varicocele being 3.2%, and of which only 13% were aware of their condition. Although this study shows a low incidence of genital abnormality in the study population, only 13% were aware of the GE prior to assessment. These findings demonstrate a low incidence of GA in this population. While GE is recommended during PPE, it is not a routine practice performed by family doctors or sports medicine specialists. This article attempts to raise awareness of the importance of GE in PPE as a preventive health strategy. Copyright © 2014 Asociación Española de Pediatría. Published by Elsevier Espana.

Abstract Determinants of HIV-infected women's genital tract mucosal immune health are not well understood. Because raltegravir (RAL) achieves relatively higher genital tract concentrations than ritonavir-boosted atazanavir (ATV), we examined whether an RAL-based regimen is associated with improved cervical immune reconstitution and less activation in HIV+ women compared to an ATV-based regimen. Peripheral blood, cervical brushings, cervical–vaginal lavage (CVL), and cervical biopsies were collected from HIV+ women on tenofovir disoproxil fumarate and emtricitabine (TDF/FTC) and either RAL (n=14) or ATV (n=19) with CD4+ T cells>300 cells/mm3 and HIV RNA<48 copies/ml. HLA-DR+CD38+ T cells were measured in blood and cervical cells using flow cytometry, CD4+ and CD8+ T cells were quantified in cervical biopsies by immunofluorescent analysis, and HIV RNA (VL), ATV, and RAL concentrations were measured in CVL. In a linear regression model of log(CVL concentration) versus both log(plasma concentration) and treatment group, the RAL CVL level was 519% (95% CI: 133, 1,525%) higher than for ATV (p<0.001). Genital tract VL was undetectable in 90% of subjects and did not differ by regimen. There were no significant differences between groups in terms of cervical %HLA-DR+CD38+CD4+ or CD8+ T cells, CD4+ or CD8+ T cells/mm2, or CD4:CD8 ratio. After adjusting for treatment time and group, the CVL:plasma drug ratio was not associated with the cervical CD4:CD8 ratio or immune activation (p>0.6). Despite significantly higher genital tract penetration of RAL compared to ATV, there were no significant differences in cervical immune activation or reconstitution between women on these regimens, suggesting both drug regimens achieve adequate genital tract levels to suppress virus replication.

While ascension of Chlamydia trachomatis into the upper genital tract of women can cause pelvic inflammatory disease and Fallopian tube damage, most infections elicit no symptoms or overt upper genital tract pathology. Consistent with this asymptomatic clinical presentation, genital C. trachomatis infection of women generates robust TH2 immunity. As an animal model that modeled this response would be invaluable for delineating bacterial pathogenesis and human host defenses, herein we explored if pathogen-specific TH2 immunity is similarly elicited by intravaginal (ivag) infection of mice with oculogenital C. trachomatis serovars. Analogous to clinical infection, ascension of primary C. trachomatis infection into the mouse upper genital tract produced no obvious tissue damage. Clearance of ivag challenge infection was mediated by interferon (IFN)-γ-producing CD4+ T cells, while IFN-γ signaling blockade concomitant with a single ivag challenge promoted tissue damage by enhancing Chlamydia-specific TH17 immunity. Likewise, IFN-γ and IL-17 signaling blockade or CD4+ T cell depletion eliminated the genital pathology produced in untreated controls by multiple ivag challenge infections. Conversely, we were unable to detect formation of pathogen-specific TH2 immunity in C. trachomatis-infected mice. Together, our work revealed C. trachomatis infection of mice generates TH1 and TH17 immune responses that promote pathogen clearance and immunopathological tissue damage. Absence of Chlamydia-specific TH2 immunity in these mice newly highlights the need to identify experimental models of C. trachomatis genital infection that more closely recapitulate the human host response.

Female guinea pigs were treated daily with 1 mg of beta-estradiol-3-benzoate intramuscularly beginning 14 days before intravaginal inoculation with the chlamydial agent of guinea pig inclusion conjunctivitis and continuing during the course of the infection. Treatment with estradiol was found to markedly influence the course of genital infection with the chlamydial agent of guinea pig inclusion conjunctivitis, producing infections of greater intensity and longer duration than those in control animals. Moreover, pathogenesis was altered in that ascending infection was observed, resulting in endometritis, cystic salpingitis, and cystitis. Infection in the controls was limited to the cervix and vagina. Estradiol treatment increased the apparent number of infected cells in the cervix and vagina as detected by histopathology and immunofluorescent staining. Humoral and cell-mediated immune responses to the chlamydial agent of guinea pig inclusion conjunctivitis were comparable in estradiol-treated and untreated animals. These data indicate that hormonal manipulation may have profound effects on the course of chlamydial genital infections. Images PMID:7141709

Definition of chronic male genital tract inflammation and its impact on male infertility is still a matter of debate. In particular, DNA integrity has been reported to be disturbed in subfertile men. Thus, the aim of this study was to investigate an association of DNA integrity to altered standard semen parameters as well as inflammatory parameters such as peroxidase-positive cells, macrophages and seminal interleukin-6 concentration. Macrophages were detected by CD18/HLA-Dr staining, and DNA integrity was analysed by acridine orange staining using flow cytometry. Interleukin-6 was detected by ELISA. Normal DNA integrity showed a significant correlation to sperm number and progressive motility. Moreover, a significant inverse correlation of DNA integrity to Interleukin-6 and macrophages could be demonstrated. Further on, seminal interleukin-6 also significantly correlated to macrophages. No association has been observed between the number of peroxidase-positive cells and normal DNA integrity. As disturbed DNA integrity has been reported to negatively influence spermatozoon-egg interaction and even fertilisation rates following ICSI, and as early miscarriages have been associated with sperm DNA damage, it should be screened very carefully for male genital tract inflammations in couples undergoing infertility treatment. Measuring Interleukin-6 seems superior to assessment of the number of leucocytes alone and additional assessment of DNA integrity into the diagnostic work-up should be considered. © 2015 Blackwell Verlag GmbH.
The course of development of the human genital tract is undifferentiated to the 9th week of development. At this time two symmetrical paired ducts known as the mesonephric (MD) and paramesonephric ducts (PMD) are present, which together with the urogenital sinus provide the tissue sources for internal and external genital development. Normal differentiation of the bipotential external genitalia and reproductive ducts are dependent upon the presence or absence of certain hormones. Masculinization of the internal and external genitalia during fetal development depends on the existence of two discrete testicular hormones. Testosterone secreted from Leydig cells induces the differentiation of the mesonephric ducts into the epididymis, vasa deferentia and seminal vesicles, whereas anti-Müllerian hormone (AMH) produced by Sertoli cells induces the regression of the paramesonephric ducts. The absence of AMH action in early fetal life results in the formation of the fallopian tubes, uterus and upper third of the vagina. In some target tissues, testosterone is converted to dihydrotestosterone, which is responsible for the masculinization of the urogenital sinus and external genitalia.

The occurrence of genital swellings was examined in adult female silvered langurs (Trachypithecus cristatus). In contrast to the exaggerated swellings found in cercopithecines and apes, genital swellings in silvered langurs are confined to the vulva and the surrounding perineum, but they may nevertheless convey information similar to that of exaggerated swellings (i.e., correlate with the receptive period and fertility). If so, genital swellings would be expected to occur most frequently in cycling females, and sexual behavior and male interest should most frequently involve females with swellings. Swellings during gestation, if they occur at all, should be most pronounced at the beginning. Swelling sizes (in three size categories) in nine adult females were examined throughout different reproductive states (cycling, pregnant, and lactating), and in relation to proceptivity, receptivity, and attractivity. Data were collected from November 2002 through March 2004 (on 500 of the 502 calendar days) at the Wildlife Conservation Society's Bronx Zoo. Female sexual behavior (proceptivity and receptivity) and male inspection (attractivity) were recorded each day for 6 hr by video camera (2,948 hr total) and analyzed as present or absent for each female day. Swellings were assessed directly (not from videotapes). In contrast to the predictions, swellings occurred significantly less frequently in cycling females (compared to pregnant females) and no regular, cyclic pattern could be detected. Some females conceived without a swelling. Female attractivity was independent of swellings but coincided with proceptive behavior. Swellings occurred most frequently in pregnant females, especially toward the end of the gestation period. Therefore, genital swellings in silvered langurs are not similar to exaggerated swellings or the smaller genital swellings that have been described for some other primates. It is currently not clear what they signal to conspecifics. Male behavior needs

The primitive anthropological meaning of genital ornamentation is not clearly defined and the origin of penile intervention for decorative purposes is lost in time. Corporeal decoration was practiced in the Upper Paleolithic period. We discuss the existing evidence on the practice of phallic piercing, scarring and tattooing in prehistory. We studied the archaeological and artistic evidence regarding explicit genital male representations in portable art made in Europe approximately 38,000 to 11,000 years ago with special emphasis on decorations suggesting genital ornamentation. Archaeological evidence that has survived to our day includes 42 phallic pieces, of which 30 (71.4%) show intentional marks to a different extent with a probable decorative purpose. Of these ornamental elements 18 (60%) were recovered from the upper Magdalenian period (11,000 to 12,700 years ago) in France and Spain, and 23 (76.7%) belong to the category of perforated batons. Decorations show lines (70% of objects), plaques (26.7%), dots/holes (23.3%) or even human/animal forms (13.3%). These designs most probably represent skin scarification, cutting, piercing and tattooing. Notably there are some technical similarities between the motifs represented and some designs present in symbolic cave wall art. This evidence may show the anthropological origin of current male genital piercing and tattooing. European Paleolithic art shows decoration explicitly represented in a high proportion of portable art objects with a phallic form that have survived to our day. Decorative rituals of male genital tattooing, piercing and scarification may have been practiced during Paleolithic times.

Antagonistic sexual coevolution stems from the notion that male and female interests over reproduction are in conflict. Such conflicts appear to be particularly obvious when male genital armature inflicts damage to the female reproductive tract resulting in reduced female longevity. However, studies of mating frequency, genital damage and female longevity are difficult to interpret because females not only sustain more genital damage, but also receive more seminal fluid when they engage in multiple copulations. Here, we attempt to disentangle the effects of genital damage and seminal fluid transfer on female longevity in the beetle Callosobruchus maculatus (Coleoptera: Bruchidae). Males copulating for the sixth time in succession inflicted greater levels of genital damage, but transferred smaller ejaculates in comparison with virgin males. The number of copulations performed by males was negatively related to female fecundity and positively related to female longevity, suggesting a trade-off between fecundity and longevity. However, inclusion of fecundity as a covariate revealed sperm and/or seminal fluid transfer to have a negative impact on female longevity above that caused by the fecundity–longevity trade-off. The consequences of multiple copulations on female longevity were examined. Females that mated twice laid more eggs and died sooner than those that mated once. However, incorporation of fecundity as a covariate into our statistical model removed the effect of female mating frequency on female longevity, indicating that double-mated females suffer greater mortality owing to the trade-off between fecundity and longevity. Males of this species are known to transfer very large ejaculates (up to 8% of their body weight), which may represent a significant nutritional benefit to females. However, the receipt of large ejaculates appears to carry costs. Thus, the interpretation of multiple mating experiments on female longevity and associated functional

Genital odor is an uncommon condition characterized by an offensive and malodorous smell in the genital area. Although the etiology of foul genital odor is multifactorial, an important cause is sweat secretion and decomposition of sweat components by bacteria. Different methods are effective in reducing body odor secondary to bromhidrosis. Conservative methods only act for a short period of time, and more invasive surgical methods carry risk of complications or are inapplicable for the genital region. A patient with localized foul odor in the genital hair bearing area was treated with botulinum toxin A. Botulinum toxin A was effective in creating an odorless and anhydrous response in the genital region, and no major adverse effects were noted during a follow-up of 9 months after injection. Local injection of botulinum toxin A appears to be a useful treatment for foul genital odor related to sweat glands activity.

Genital herpes is an intractable disease caused mainly by herpes simplex virus (HSV) type 2 (HSV-2), and is a major concern in public health. A previous infection with HSV type 1 (HSV-1) enhances protection against primary HSV-2 infection to some extent. In this study, we evaluated the ability of HF10, a naturally occurring replication-competent HSV-1 mutant, to protect against genital infection in mice caused by HSV-2. Subcutaneous inoculation of HF10-immunized mice against lethal infection by HSV-2, and attenuated the development of genital ulcer diseases. Immunization with HF10 inhibited HSV-2 replication in the mouse vagina, reduced local inflammation, controlled emergence of neurological dysfunctions of HSV-2 infection, and increased survival. In HF10-immunized mice, we observed rapid and increased production of interferon-γ in the vagina in response to HSV-2 infection, and numerous CD4(+) and a few CD8(+) T cells localized to the infective focus. CD4(+) T cells invaded the mucosal subepithelial lamina propria. Thus, the protective effect of HF10 was related to induction of cellular immunity, mediated primarily by Th1 CD4(+) cells. These data indicate that the live attenuated HSV-1 mutant strain HF10 is a promising candidate antigen for a vaccine against genital herpes caused by HSV-2.

Anti-chlamydial immunity involves efficient presentation of antigens (Ag) to effector cells resulting in Ag-specific immune responses. There is limited information on inherent underlying mechanisms regulating these events. Previous studies from our laboratory have established that select microRNAs (miRs) function as molecular regulators of immunity in Chlamydia muridarum (Cm) genital infection. In this report, we investigated immune cell type-specific miRs, i.e. miR-155 and -182, and the role in Ag-specific immunity. We observed significant up-regulation of miR-155 in C57BL/6 bone marrow derived dendritic cells (BMDC), and miR-182 in splenic Ag-specific CD4+ T-cells. Using mimics and inhibitors, we determined that miR-155 contributed to BMDC activation following Cm infection. Co-cultures of miR-155 over-expressed in BMDC and miR-182 over-expressed in Ag-specific CD4+ T-cells, or miR-155−/− BMDC with miR-182 inhibitor treated Ag-specific CD4+ T-cells, resulted in IFN-γ production comparable to Ag-specific CD4+ T-cells isolated from Cm infected mice. Additionally, miR-182 was significantly up-regulated in intranasally vaccinated mice protected against Cm infection. In vivo depletion of miR-182 resulted in reduction in Ag-specific IFN-γ and genital pathology in Cm infected mice. To the best of our knowledge, this is the first study to report an interaction of miR-155 (in Cm infected DC) and miR-182 (in CD4+ T-cell) resulting in Ag specific immune responses against genital Cm.

Vaginal chronic graft-versus-host-disease (cGVHD) is a common complication of stem cell transplantation. Human papillomavirus (HPV) disease can reactivate after transplantation, presumably because of immune factors affecting systemic immunity, such as waning antibody titers, impaired T- and B- lymphocyte responses, and the use of immunosuppressive therapies. However, a relationship between the use of local immunosuppressive agents and HPV reactivation and spread has not been previously described, to our knowledge. A 30-year-old woman, 2 years post transplant receiving systemic cyclosporine for cGVHD, was treated with vaginal dilators, topical corticosteroids, and estrogen for vaginal cGVHD. Colposcopy and biopsy for abnormal cytology revealed condylomatous cervicitis. Over the next 4 months. while continuing dilator therapy, linear verrucous lesions developed in the vagina and vulva, and were successfully treated with laser therapy. Use of local immunosuppression and dilators for genital GVHD can enhance spread of HPV infection. Integration of HPV screening and treatment into the care of women with genital cGVHD and development of strategies to manage both conditions simultaneously is warranted. PMID:23710698

The effect of various doses of estradiol on genital tract infection by the chlamydial agent of guinea pig inclusion conjunctivitis (GPIC) was investigated in ovariectomized guinea pigs. Prolongation of infection, as determined by chlamydial inclusion counts of cells in Giemsa-stained smears of vaginal scrapings, was observed in animals receiving daily doses of 1.0, 10.0, 100.0, or 1000 micrograms of estradiol. In contrast to controls, ascending infection resulting in endometritis was found in animals receiving doses of greater than or equal to 1.0 microgram of estradiol per day. Response to estradiol treatment was reflected in an increase in cervical-uterine wet weight and uterine wall thickness. No differences were observed in time of appearance of antibody titers to GPIC in serum, but a delay in appearance of IgA antibody to GPIC in genital secretions was found in estradiol-treated animals receiving doses of greater than or equal to 1.0 microgram per day.

Isolated necrotizing arteritis (INA) of the polyarteritis-nodosa type localized to the female genital tract is rare. Approximately 30 case reports have been published to date. Eleven additional patients are described here, all with a favorable follow-up. INA is usually localized in the uterine cervix, but, when multifocal lesions are present, the latter is almost always involved. Patients most frequently report menorrhagia or postmenopausal bleeding. With immunohistochemical studies, immune-complex deposits (IgM, IgG, and C'3) in 7 of 11 patients with INA of the female genital tract were demonstrated for the first time. The inflammatory cells were composed mainly of T-lymphocytes with macrophages and scarce B-lymphocytes also present. These results suggest that INA is primarily an immune complex-mediated disease, implicating humoral and cellular mediator systems. Possible pathogenetic factors of INA are immune complex-mediated hypersensitivity reactions to drugs, foreign materials (after cone biopsy or curettage), and cancers, or an autoimmune reaction against constituents of the vessel walls caused by tissue injury after local surgical intervention through in situ immune-complex formation.

We conducted a cross-sectional study on the occurrence of a specific type of genital human papillomavirus (HPV) among long-term monogamous male partners of women with cervical dysplasia and genital warts. The purpose of the study was to improve knowledge with regards to the management of these couples. The presence of genital HPV-DNA was detected by PCR with broad spectrum primers followed by hybridization. 82 males met the study criteria, 41 in each group. Genital HPV-DNA prevalence was 67.5% in the genital warts group and 72.2% in the cervical dysplasia group. The prevalence of high risk HPVs was higher in the cervical dysplasia group, while low risk HPVs were more prevalent in the genital warts group (p < .05). The prevalence of HPV in males was independent of the duration of the relationship (73.5% for 6-24 months and 66.7% for longer relationships). In conclusion, our results suggest that the prevalence of the genital HPV infection in both groups of male partners is comparable and very high, but the spectrum of HPV types varies significantly. The presence of the genital HPV infection in male sexual partners seems to be independent of the duration of the relationship. Applying the HPV vaccination to boys may prevent this phenomenon. © 2016 Wiley Periodicals, Inc.

Marked diversification of genital morphology is common in internally fertilizing animals. Although sexual selection may be the primary process controlling genital evolution, factors promoting genital evolution are controversial, and the genetic background of genital morphology is poorly understood. We analyzed the genetic basis of species-specific genital morphologies in carabid beetles of the subgenus Ohomopterus (genus Carabus, Carabidae) using two parapatric species with hybrid zones. Biometric analyses on experimental F(1) and backcross populations revealed that inheritance of genital morphology is polygenic. Applying Lande's modification of the Castle-Wright estimator to population means and variances to estimate the minimum number of genes involved, we found that a relatively small number of loci is responsible for species differences in genital morphology. In addition, joint-scaling tests indicated that the additive genetic effect accounts for most interspecific differences in genital traits, but dominance and epistatic genetic effects also play roles. Overall, the genetic basis of male and female genitalia is fairly simple, enabling these traits to respond quickly to selection pressures and to diverge rapidly. Our results provide insight into the diversification of genital morphology in carabid beetles, and will hopefully stimulate further studies on the genetic basis of genitalia, such as mapping of quantitative trait loci affecting species-specific genital morphology.

Many women have doubts about the normality of the physical appearance of their vulvas. This study measured genital self-image in a convenience sample of college-educated women, and assessed whether exposure to pictures of natural vulvas influenced their genital self-image. Forty-three women were either shown pictures of natural vulvas (N = 29) or pictures of neutral objects (N = 14). Genital self-image was measured before and after exposure to the pictures and two weeks later. Sexual function, sexual distress, self-esteem and trait anxiety were measured to investigate whether these factors influenced genital self-image scores after vulva picture exposure. A majority of the participants felt generally positively about their genitals. Having been exposed to pictures of natural vulvas resulted in an even more positive genital self-image, irrespective of levels of sexual function, sexual distress, self-esteem and trait anxiety. In the women who had seen the vulva pictures, the positive effect on genital self-image was still present after two weeks. The results of this study seem to indicate that even in young women with a relatively positive genital self-image, exposure to pictures of a large variety of natural vulvas positively affects genital self-image. This finding may suggest that exposure to pictures of natural vulvas may also lead to a more positive genital self-image in women who consider labiaplasty.

Epidemiological studies relating genital herpetic infection to cervical carcinoma are reviewed. The high frequency of herpes simplex virus type 2 (HSV-2) antibodies in young women (21 years or younger) with cervical carcinoma in situ and in women with dysplasia or carcinoma in situ, matched for various sexual attributes to control women, provide support for a causal relation. However, various laboratory, histopathological, and statistical problems associated with all epidemiological studies do not yet permit a firm conclusion as to the etiological role to the genital virus in cervical carcinogenesis. With the use of herpes-related cancer antigens or purified HSV-2 type-specific antigens, and with the possible development of protective HSV-2 vaccines, the application of epidemiological approaches may be necessary to provide the most finite evidence of causality.
The accurate description and interpretation of non-genital injuries may be crucial in cases of alleged sexual assault, and may be important in corroborating a victim's statement of events. In many cases of sexual assault, non-genital injuries may be either absent or trivial; nevertheless, even minor injuries may be of significance and need to be recorded. Injuries may be result from attempts to restrain the victim, whereas others (e.g. bite marks) may have a sexual motive or be part of a sado-masochistic ritual. A standard nomenclature for injuries (i.e. using the terms 'bruises', 'abrasions', 'lacerations', 'incisions and 'stab wounds') should avoid ambiguity between medical examiners.

Genital herpes is a sexually transmitted disease. After the primary infection, the virus establishes a life-long latency in the sacral dorsal root ganglia. Recurrences may occur at an unpredictable rate. The clinical signs are not always easy to recognize and viral identification techniques may be helpful such as immunohistochemistry and in situ hybridization on Tzanck smears and muco-cutaneous biopsies. The treatment of genital herpes can follow one of three strategies using antiviral drugs, non-specific immunomodulators, and vaccination. The new oral antiviral drugs decrease the severity of clinical manifestations without, however, providing a definitive cure. In this article recent knowledge about the clinical aspects, differential diagnosis, diagnostic methods, treatment options and management is reviewed.

An experimental model of the primary genital herpes (herpes simplex type 2, HSV-2) in the female guinea pigs was suggested to study the infectious process activity of polyprenyl phosphates (PPP) and PPP+acyclovir (AC) complex treatment. The morphofunctional features of the guinea pig ovaries were studied in the control and experimental groups (the latter were inoculated with PPP and/or AC as a primary infection treatment) at the stage of the recurrent genital herpes aggravation. It was shown that in the case of combined PPP +AC use significant changes in the disease symptoms were observed, as well as a decrease in the infectious process activity and duration, and positive remote effect on the ovarian morphophysiology.

The aesthetic and functional procedures that comprise female genital cosmetic surgery (FGCS) include traditional vaginal prolapse procedures as well as cosmetic vulvar and labial procedures. The line between cosmetic and medically indicated surgical procedures is blurred, and today many operations are performed for both purposes. The contributions of gynecologists and reconstructive pelvic surgeons are crucial in this debate. Aesthetic vaginal surgeons may unintentionally blur legitimate female pelvic floor disorders with other aesthetic conditions. In the absence of quality outcome data, the value of FGCS in improving sexual function remains uncertain. Women seeking FGCS need to be educated about the range and variation of labia widths and genital appearance, and should be evaluated for true pelvic support disorders such as pelvic organ prolapse and stress urinary incontinence. Women seeking FGCS should also be screened for psychological conditions and should act autonomously without coercion from partners or surgeons with proprietary conflicts of interest.

Infection of the genital organs by human papillomavirus (HPV) is the most commonly diagnosed sexually transmitted disease. Papillomaviruses lead to a contact infection of the epithelium and present with different clinical and histological signs. With the exception of the best known clinical manifestation Condylomata acuminata, subclinical infections can be only diagnosed from a stepwise examination. Physiological results from both men and women may be falsely explained as being caused by viruses, and can lead to an incorrect therapy. Genital papilla (Papillae coronae vulvae et glandis) present as atavistic cutaneous papilla a normal situation but with functional significance. Differences in clinical symptoms as well as the possibilities of further differentiation can be obtained by means of pictures taken during colposcopy.

Female genital mutilation is a cultural practice that can adversely affect the health of women. Vulval complications of female circumcision in 39 patients managed at the University College Hospital, Ibadan, Nigeria over a period of 10 years were reviewed. The complications were: labial adhesions of varying degrees (51.3%) and clitoral retention cysts (48.7%). However, both types of complications occurred concurrently in two (5.1%) patients. All patients were treated surgically with good outcome. The only immediate complication of treatment was secondary haemorrhage in one patient with clitoral cyst. Regrettably, one patient with labial adhesion required a repeat surgical procedure 2 months later. The histological examination of all the retention cysts revealed epidermal inclusion cysts. Emphasising the reproductive health implications of female genital mutilation may prove an effective strategy towards eradication of the practice.

Smoking has well-recognized endocrine disrupting effects in humans that have been linked specifically to nicotine in animal models. Nicotine's perinatal effects on genital development in mice, which is interpreted as a measure of endocrine disrupting activity, were evaluated in this report. Pregnant C57B/6J dams were administered 50 microg/ml nicotine in drinking water from gestational day 9 until pups were weaned. Their pups' anogenital distances and weights were measured at birth and at weaning. A subset of the pups was weighed again in adulthood. Female and male mice had significantly reduced anogenital distance at birth; however, by 34 days of age, differences in anogenital distance were no longer apparent, while body weight, which had been equal at birth and weaning, was significantly reduced in mice exposed to perinatal nicotine. Perinatal nicotine exposure significantly delayed genital development and altered adolescent body weight in this model. Copyright 2010 Elsevier Inc. All rights reserved.

The risk of lower genital tract neoplasia is increased in women infected with HIV. This has been best demonstrated in cervical squamous intraepithelial lesions, but has also been observed in vulvar and perianal intraepithelial lesions in some studies. Alterations in the prevalence and natural history of human papillomavirus infections of the lower genital tract appear to account for much of the increase. HIV-infected women are approximately four times more likely to be infected with human papillomavirus (including infection with high oncogenic risk human papillomavirus types) than are HIV-uninfected women, and these infections are more likely to be persistent. Human papilomavirus-associated lesions may be more difficult to treat in HIV-infected women. These data highlight the need to develop effective cervical cancer prevention programs for HIV-infected women.

Summary Our understanding of the bacterial species inhabiting the female genital tract has been limited primarily by our ability to detect them. Early investigations using microscopy and culture-based techniques identified lactobacilli as the predominant members of the vaginal microbiota and suggested that these organisms might serve a protective function at the mucosal surface. Improvements in cultivation techniques and the development of molecular-based detection strategies validated these early findings and enabled us to recognize that the microbiota of the female genital tract is much more complex than previously suspected. Disruption of the vaginal microbial community due to invasion of exogenous organisms or by overgrowth of one or more endogenous species has important health implications for both the mother and newborn.

Despite the global outcry against female genital cutting (FGC), the practice continues in many African communities. The morbidity of this practice on the girl child deserves more attention. To determine the genital lesions complicating childhood FGC and the underlying factors that sustain this practice among the Igbos in south-east Nigeria. Prospective evaluation of girls with genital complications of FGC between January 2003 and June 2005 at the Federal Medical Centre, Owerri, south-east Nigeria. The girls' mothers were interviewed at presentation and subsequent visits to determine their perception and attitudes towards FGC. The average age at presentation was 3.5 years (range 1-5) and the genital cutting procedures were performed 8-90 days after birth. The procedure was undertaken by traditional practitioners in 14 (66.7%) girls and by nurses in 7 (33.3%) girls. Twelve girls (57.1%) had type I genital cutting and nine (42.9%) type II. Inclusion clitoral dermoid cyst and labial fusion were the complications in 13 (61.9%) and eight (38.1%), respectively. Treatment involved complete excision of the cysts and operative division of the labial fusion. Post-operative complications were wound infection (5) and labial adhesion (2). With duration of admission ranging from 3 to 5 days, the average cost of managing each child was $120. Of the girls' mothers, 15 (71.4%) had been educated to secondary level and 17 (80.1%) were aware of the campaign against FGC. Regrettably, all the mothers had genital cutting themselves during childhood and 13 (61.9%) stated that they would like to perpetuate the practice for socio-cultural reasons. Despite this, they all volunteered that FGC is enforced by the child's paternal relations. Childhood FGC contributes to appreciable morbidity among girls, a large proportion of whom are not managed in a hospital setting. The cost of managing these complications can be enormous, especially in low-resource settings. Girl child education to tertiary

SUMMARY Chlamydia trachomatis is the leading cause of bacterial sexually transmitted disease worldwide, and despite significant advances in chlamydial research, a prophylactic vaccine has yet to be developed. This Gram-negative obligate intracellular bacterium, which often causes asymptomatic infection, may cause pelvic inflammatory disease (PID), ectopic pregnancies, scarring of the fallopian tubes, miscarriage, and infertility when left untreated. In the genital tract, Chlamydia trachomatis infects primarily epithelial cells and requires Th1 immunity for optimal clearance. This review first focuses on the immune cells important in a chlamydial infection. Second, we summarize the research and challenges associated with developing a chlamydial vaccine that elicits a protective Th1-mediated immune response without inducing adverse immunopathologies.

Genital herpes is one of the most prevalent sexually transmitted infections in both the developing and developed world. Following infection, individuals experience life-long latency associated with sporadic ulcerative outbreaks. Despite many efforts, no vaccine has yet been licensed for human use. Herein, we demonstrated that nasal immunization with an adjuvanted HSV-2 gD envelope protein mounts significant protection to primary infection as well as the establishment of latency and recurrent genital herpes in guinea pigs. Nasal immunization was shown to elicit specific T cell proliferative and IFN-γ responses as well as systemic and vaginal gD-specific IgG antibody (Ab) responses. Furthermore, systemic IgG Abs displayed potent HSV-2 neutralizing properties and high avidity. By employing a competitive surface plasmon resonance (SPR) analysis combined with a battery of known gD-specific neutralizing monoclonal Abs (MAbs), we showed that nasal immunization generated IgG Abs directed to two major discontinuous neutralizing epitopes of gD. These results highlight the potential of nasal immunization with an adjuvanted HSV-2 envelope protein for induction of protective immunity to primary and recurrent genital herpes.

Herpes simplex virus 2 (HSV-2) infects the genital mucosa and establishes a life-long infection in sensory ganglia. After primary infection HSV-2 may reactivate causing recurrent genital ulcerations. HSV-2 infection is prevalent, and globally more than 400 million individuals are infected. As clinical trials have failed to show protection against HSV-2 infection, new vaccine candidates are warranted. The secreted glycoprotein G (sgG-2) of HSV-2 was evaluated as a prophylactic vaccine in mice using two different immunization and adjuvant protocols. The protocol with three intramuscular immunizations combining sgG-2 with cytosine-phosphate-guanine dinucleotide (CpG) motifs and alum induced almost complete protection from genital and systemic disease after intra-vaginal challenge with HSV-2. Robust immunoglobulin G (IgG) antibody titers were detected with no neutralization activity. Purified splenic CD4+ T cells proliferated and produced interferon-γ (IFN-γ) when re-stimulated with the antigen in vitro. sgG-2 + adjuvant intra-muscularly immunized mice showed a significant reduction of infectious HSV-2 and increased IFN-γ levels in vaginal washes. The HSV-2 DNA copy numbers were significantly reduced in dorsal root ganglia, spinal cord, and in serum at day six or day 21 post challenge. We show that a sgG-2 based vaccine is highly effective and can be considered as a novel candidate in the development of a prophylactic vaccine against HSV-2 infection.

Vestibular papillomatosis (VP) is a benign condition of the female genitalia that may be mistaken for condyloma acuminatum (genital warts). In contrast to condylomata, lesions of VP each grow from a distinct mucosal insertion; match the color of the surrounding mucosa; and are symmetrically distributed, limited to the inner labia minora and vaginal introitus. Recognition of this entity will help to prevent unnecessary stress, testing, and discomfort.

In clinical practice, treatment of genital tract infections is based on administration of either antibiotics or antiseptics. While antibiotics may be applied systemically or topically, antiseptics may be applied only topically. In case of bacterial vaginosis (BV), antibiotic therapy may often be limited and side effects due to systemic administration may develop. Polihexanide (PHMB) is a promising option for the topical treatment of genital tract infections, in particular BV and vaginitis. A systematic search for publications on the use of PHMB for the treatment of genital infections in two electronic databases was performed. Titles, abstracts and citations were imported into a reference database. Duplicates were removed and two reviewers assessed each identified publication separately. Among a total of 204 references, 3 prospective randomized trials were identified. Two trials treated BV infections with PHMB in comparison to clindamycin as antibiotic standard therapy with no significant differences either in safety or in efficacy. The third controlled trial investigated the clinical efficacy of PHMB compared to placebo in the treatment of human papilloma virus. Patients treated with PHMB daily for up to 16-weeks showed significantly higher (52%) clearance of genital warts as compared to patients treated with placebo (4%). PHMB may be a clinically effective alternative for the treatment of BV and human papilloma virus. Although PHMB-based antiseptics are available since the late 90s, controlled trials to investigate its clinical potential for antiseptic treatment are scant. Clinical use of antiseptics for the treatment of infectious diseases should be explored and supported further. Copyright © 2012 S. Karger AG, Basel.

We conducted a literature review to determine the clinical characteristics of genital sarcoma during pregnancy. The systematic literature search was conducted using the search engines PubMed and MEDLINE with keywords "sarcoma" and "pregnancy" and was limited to female genital organs such as ovary, uterus, cervix, vagina, vulva, and retroperitoneal sarcoma. Kaposi's sarcoma, metastatic sarcoma, history of sarcoma, bone sarcoma located in pelvis, and fetal sarcoma were excluded in this study. There were 40 cases of genital sarcoma during pregnancy between 1955 and 2007. The majority of the cases were uterine sarcoma (37.5%), followed by retroperitoneal sarcoma (27.5%), vulvar sarcoma (22.5%), and vaginal sarcoma (12.5%). Mean age of the patient was 27.8 +/- 7.0. The distribution in the onset of symptoms had two peaks: first trimester (27.5%) and third trimester (50.0%). Growing mass (42.5%), abdominal pain (30.0%), and vaginal bleeding (22.5%) were the three most common symptoms. Incidental diagnosis was made in 22.5% and included during cesarean section (12.5%) and routine pelvic exam (7.5%). The cases initially not suspicious for malignancy were 42.5%. Thirty-three (82.5%) cases had live-born infants with term delivery in 55.2%. Mean birth weight was 2843 +/- 791 g, and male infants were more common (66.7%). Intrauterine growth retardation was seen in 12.5% of cases. Preterm labor was a common complication. Median survival period was 2.5 years (95% confidence, 1.9 to 3.1). The 2-, 3-, and 5-year cumulative survival rates were 60%, 38%, and 17%, respectively. Genital sarcomas in pregnancy are rare. There is a delay in diagnosis due to low index of suspicion. A majority had live births, and the 5-year survival is similar to that of advanced-stage sarcoma in nonpregnant women.

Frequency of cervical cancer related to Human Papilloma Virus (HPV) has increased remarkably in less-developed countries. Hence, applying capable diagnostic methods is urgently needed, as is having a therapeutic strategy as an effective step for cervical cancer prevention. The aim of this study was to investigate the prevalence of various multi-type HPV infection patterns and their possible rising incidence in women with genital infections. This descriptive study was conducted on women who attended referral clinical laboratories in Tehran for genital infections from January 2012 until December 2013. A total of 1387 archival cervical scraping and lesion specimens were collected from referred women. HPV genotyping was performed using approved HPV commercial diagnostic technologies with either INNO-LiPA HPV or Geno Array Test kits. HPV was positive in 563 cases (40.59%) with mean age of 32.35±9.96. Single, multiple HPV genotypes and untypable cases were detected in 398 (70.69%), 160 (28.42%) and 5 (0.89%) cases, respectively. Multiple HPV infections were detected in 92 (57.5%), 42 (26.2%), 17 (10.6%) and 9 (5.7%) cases as two, three, four and five or more genotypes, respectively. The prevalence of 32 HPV genotypes was determined one by one. Seventeen HPV genotypes were identified in 95.78% of all positive infections. Five dominant genotypes, HPV6, 16, 53, 11 and 31, were identified in a total of 52.35%of the HPV positive cases. In the present study, we were able to evaluate the rate of multiple HPV types in genital infections. Nevertheless, it is necessary to evaluate the role of the dominant HPV low-risk types and the new probably high-risk genotypes, such as HPV53, in the increasing incidences of genital infections.

Doctoring the genitals is compatible with a recognizable conception of social medicine. This commentary critically examines the distinction between medical and nonmedical procedures; presents an alternative account of Sohaila Bastami's personal reaction to the anonymous caller's request for referral information concerning hymen reconstruction surgery; and makes use of Yelp to simulate the caller's procedure for locating a helpful practitioner. Yelp is a very useful informational search engine that does not subject its users to a moral examination.

Genital ulcers are common manifestations of infectious disease. The incidence of genital ulcers featuring a chronic course has increased since the beginning of the AIDS epidemic. The purpose of this 18-month cross-sectional study was to determine the main infectious causes of chronic genital ulcers (CGU) and their correlation with HIV infection. A total of 29 patients with CGU defined as an ulcer showing no sign of healing after more than one month were studied. Mean age ranged from 24 to 54 years. The male-to-female sex ratio was 1:5. The etiology was herpes in 19 cases (65.5 p. 100), chancroid in 6 cases (20.6 p. 100), streptococcal infection in 2 cases (6.8 p. 100), Pseudomonas aeruginosa infection in 1 case (3.4 p. 100) and cutaneous amibiasis in 1 case (3.4 p. 100). Twenty-two patients (75.8 p. 100) presented HIV infection including 16 with HIV1 and 6 with HIV1 and HIV2. All patients with herpes were HIV-positive. Eighteen of these patients were in stage C3 of HIV infection. Genital herpes was the main etiology of UGC in patients with HIV infection (p < 0.001). Conversely chancroid was the main etiology in patients without HIV infection (p < 0.05). This finding suggests that herpetic CGU is highly suggestive of AIDS whereas chancroid CGU is not. Although syphilis is widespread in Africa, it was not a cause of CGU in this study. Search for herpes simplex virus or Haemophilus ducreyi in patients with CGU is an important criteria for presumptive diagnosis of AIDS in Africa.

Genital warts caused by human papillomavirus (HPV) infection are the most common sexually transmitted disease leading to anogential lesions. Although the laser therapy has been shown to be effective in a number of conditions, the use of laser diode vaporization in urological applications and the understanding on its effectiveness as a treatment for various urological conditions is limited. Therefore, the aim of this study was to evaluate the efficacy of diode laser vaporization as a treatment for genital lesions. Patients presenting with genital lesions at the urology outpatient clinic at Coronel Mota Hospital, between March 2008 and October 2014, were enrolled into the study. Data collected included age, gender, duration of the lesion, site of the lesion and numbers of the lesions, length of follow-up, recurrence of lesions after treatment and whether there were any complications. A total of 92 patients were enrolled in the study; 92.4% (n = 85) male; mean age (± SD) 27.92 ± 8.272 years. The patients presented with a total of 296 lesions, with a median of 3 lesions each, including penis (n = 78), urethra (n = 4) lesions, and scrotum (n = 2) lesions. Lesions ranged in size from 0.1 to 0.5 cm(2), most commonly 0.3 cm(2) (n = 38; 41.3%), 0.4 cm(2) (n = 21; 22.8%) or 0.5 cm(2) (n = 20; 21.7%). Patients most commonly reported that they had their lesions for a duration of 12 (n = 29; 31.5%) or 6 months (n = 23; 25.0%). Eighteen patients (19.6%) had a recurrence after their 1(st)/conventional treatment. There were no incidences of post-operative infection or complications from the laser diode vaporization. Laser diode vaporization can be considered as an alternative method for treating genital lesions in urology, with satisfactory results in terms of pain, aesthetic and minimal recurrence.

The role of tumor necrosis factor alpha (TNF-alpha) in host defense against chlamydial infection remains unclear. In order to further evaluate the relevance of TNF-alpha to host resistance in chlamydial genital tract infection, we examined the effect of local inhibition of the TNF-alpha response in normal C57 mice and in interferon gamma gene-deficient C57 mice infected intravaginally with the mouse pneumonitis agent of Chlamydia trachomatis. Since the guinea pig model of female genital tract infection more closely approximates the human in terms of ascending infection and development of pathology, we also examined the effect of local inhibition of the TNF-alpha response in guinea pigs infected intravaginally with the guinea pig strain of Chlamydia psittaci. We successfully blocked the early TNF-alpha response in the respective animal models. This blockade had no effect on the numbers of organisms isolated from the genital tract during the time of TNF-alpha inhibition in mice or guinea pigs. Analysis of interleukin-1beta, macrophage inflammatory protein-2, and granulocyte macrophage-colony stimulating factor in the mouse model revealed that blockade of the TNF-alpha response did not alter the release of these proinflammatory proteins. Yet, in TNF-alpha-depleted mice, increased numbers of neutrophils were detected in the genital tract, and, in TNF-alpha-depleted guinea pigs, increased numbers of neutrophils as well as infiltrating lymphocytes were seen in the endocervix. Blockade of TNF-alpha does not affect the level of infection in mice or guinea pigs, but it may decrease TNF-alpha-induced apoptosis of infiltrating inflammatory cells.

The present study was aimed at investigating the adverse effects of dietary zearalenone (ZEA) (1.1 to 3.2 mg/kg diet) on serum hormones, morphologic and apoptotic measurements of genital organs in post-weaning gilts. A total of twenty gilts (Landrace×Yorkshire×Duroc) weaned at 21 d with an average body weight of 10.36±1.21 kg were used in the study. Gilts were fed a basal diet with an addition of 0, 1.1, 2.0, or 3.2 mg/kg purified ZEA for 18 d ad libitum. Results showed that 3.2 mg/kg ZEA challenged gilts decreased (p<0.05) the serum levels of luteinizing hormone, however, serum levels of prolactin in gilts fed the diet containing 2.0 mg/kg ZEA or more were increased (p<0.05) compared to those in the control. Linear effects on all tested serum hormones except progesterone were observed as dietary ZEA levels increased (p<0.05). Gilts fed ZEA-contaminated diet showed increase (p<0.05) in genital organs size, hyperplasia of submucosal smooth muscles in the corpus uteri in a dose-dependent manner. However, the decreased numbers of follicles in the cortex and apoptotic cells in the ovarian were observed in gilts treated with ZEA in a dose-dependent manner. Degeneration and structural abnormalities of genital organs tissues were also observed in the gilts fed diet containing 1.1 mg/kg ZEA or more. Results suggested that dietary ZEA at 1.1 to 3.2 mg/kg can induce endocrine disturbance and damage genital organs in post-weaning gilts. PMID:25557812

Screening for human papillomavirus (HPV) types was performed by a PCR-based assay on 29 women (mean age 34.0 years, range 21-48 years). HPV-DNA was demonstrated in 16 women (55.2%), with a detection rate of 37.9% in the oral cavity and 34.5% in the genital tract. HPV-16 was the most prevalent genotype (53.8%), followed by HPV-6, which was present in 34.6% of the positive samples. Other types were more rarely detected. Five subjects showed concurrent genital tract and oral cavity infections but HPV type-specific concordance was detected in only 3 patients. Multiple HPV infections were found in 9 of the 26 positive samples, where HPV-6 appeared frequently associated with the other types. These data confirm the occurrence of mixed HPV infections and the wide diffusion of different types of HPV in the genital mucosa and in the oral cavity; they also stress the need to utilize diagnostic methods with a wide typing capacity.

Human papillomavirus (HPV) is highly prevalent in men and there is an interest in further understanding the relationship between HPV infection and disease in men, including the development of genital warts, penile intraepithelial neoplasia and invasive penile carcinomas. Genital warts are caused by HPV 6/11 and are the most common clinical manifestation of HPV in men. Though they are benign and not associated with mortality, they are a source of psychosocial distress and physical discomfort. HPV infection can also develop into invasive penile carcinoma which is associated with morbidity and mortality. Approximately 40% of invasive penile carcinomas are attributable to HPV with HPV 16, 18, and 6/11 being the genotypes most commonly detected in penile tumors. Penile carcinomas of the basaloid and warty histologic subtypes are most likely to test positive for HPV. In addition to HPV infection, the risk factors most strongly associated with penile cancer are lack of neonatal circumcision, phimosis (the inability of uncircumcised men to fully retract the foreskin), and anogenital warts. Male vaccination with the quadrivalent HPV vaccine that protects against HPV 6/11/16/18 has been shown to significantly reduce HPV-associated anogenital infection and disease in men. If the quadrivalent vaccine is successfully disseminated to large segments of the young male population, there is the potential for substantial reduction in genital HPV infection and related lesions in men.

Metastases to the female genital tract from gastric cancer are rare, but they significantly worsen the prognosis of such patients. The potential routes for metastasis to the female genital tract from gastric cancer include hematogenous spread, lymphatic spread and surface implantation. The rate of lymphatic metastasis to the ovary from gastric cancer has been reported to be higher compared with that from colorectal cancer. Uterine or Fallopian tube metastases are usually secondary to ovarian metastases, which are typically identified prior to the detection of gastric cancer in half of all synchronous cases, with complaints of abdominal distention, pain, palpable mass, or abnormal uterine bleeding. The prognosis of patients with female genital tract metastases from gastric cancer is extremely poor, and is worse compared with that of other primary sites, such as the breast and colorectum. In the past, surgical intervention in such patients consisted mainly of palliative resection to relieve the symptoms associated with a sizeable pelvic mass. However, recent retrospective studies based on a relatively small number of patients have reported that surgical tumor debulking plus chemotherapy may improve the prognosis of patients with metastatic ovarian cancer originating from gastric cancer.

The prevalence of genital piercing among women is increasing. As the popularity increases, the number of complications from infection, injury, and retained jewelry is likely to rise. Techniques to remove embedded jewelry are not well described in the literature. The purpose of this report was to describe a case of a patient with a retained clitoral glans piercing, discuss a simple technique for outpatient removal, and review current evidence regarding associated risks of clitoral piercings. A 24-year-old female presented to the emergency department with an embedded clitoral glans piercing. Local anesthetic was injected into the periclitoral skin and a small superficial vertical incision was made to remove the ball of the retained barbell safely. In conclusion, among patients with retained genital piercing, outpatient removal of embedded jewelry is feasible. While the practice of female genital piercing is not regulated, piercing of the glans of the clitoris is associated with increased injury to the nerves and blood supply of the clitoris structures leading to future fibrosis and diminished function compared to piercing of the clitoral hood.

In Kenya, a new ceremony known as "Ntanira Na Mugambo," or "circumcision through words," is being offered in some rural communities as an alternative to the harmful practice of female genital mutilation. This new ceremony includes a week-long program of counseling, training, and provision of information to young women ending with a "coming of age" celebration that involves music, dancing, presents, and feasting. Since its initiation in August 1996, about 300 young women have accepted this alternative rite. Kenya is among the countries where the practice of female genital mutilation is slowly diminishing, but the mutilation is still common in at least 26 African countries and among immigrants in some developed countries. The new Kenyan rite has the advantage of requiring the cooperation and support of the communities where it is practiced. It was developed as a cooperative effort of the Kenyan Maendeleo Ya Wanawake Organization and the Program for Appropriate Technology in Health after years of research. An important aspect of Ntanira Na Mugambo is the flexibility that arises from the ability to stress various components in response to community characteristics. Its success is also linked to the fact that it involves the entire family and community and has a male motivation component. It is hoped that this nonjudgmental rite will become a widely successful strategy to eliminate female genital mutilation and improve women's health throughout the world.

Genital tract lymphoma is a rare disease; information on diagnosis, treatment and outcome are limited. We report on eight patients affected by non-Hodgkin's lymphoma of the genital tract, five from the cervix, two from the vagina and one from the vulva collected between 1987 and 1998. Age at presentation ranged from 36 to 82 (median 67) years. The commonest initial symptom was vaginal bleeding, post coital in 1 patient. Three patients complained of vescical symptoms. Ann Arbor classification was stage IAE for 6 patients. Histology, according to the IWF, was either intermediate grade (4 patients), or high grade (3 patients), not evaluable in one case. Seven patients were treated with chemotherapy (anthracycline based in four) followed by pelvic radiotherapy in five; one patient received irradiation alone. Five patients are currently alive and free of disease with follow-up ranging from 8 to 126 months. Based on our experience in this series, we support a management scheme of combination chemotherapy and radiotherapy for patients with non-Hodgkin's lymphoma of the genital tract.

Chlamydiae are intracellular bacteria that commonly cause infections of the respiratory and genital tracts, which are major clinical problems. Infections are also linked to the aetiology of diseases such as asthma, emphysema and heart disease. The clinical management of infection is problematic and antibiotic resistance is emerging. Increased understanding of immune processes that are involved in both clearance and immunopathology of chlamydial infection is critical for the development of improved treatment strategies. Here, we show that IL-13 was produced in the lungs of mice rapidly after Chlamydia muridarum (Cmu) infection and promoted susceptibility to infection. Wild-type (WT) mice had increased disease severity, bacterial load and associated inflammation compared to IL-13 deficient (-/-) mice as early as 3 days post infection (p.i.). Intratracheal instillation of IL-13 enhanced bacterial load in IL-13-/- mice. There were no differences in early IFN-g and IL-10 expression between WT and IL-13-/- mice and depletion of CD4+ T cells did not affect infection in IL-13-/- mice. Collectively, these data demonstrate a lack of CD4+ T cell involvement and a novel role for IL-13 in innate responses to infection. We also showed that IL-13 deficiency increased macrophage uptake of Cmu in vitro and in vivo. Moreover, the depletion of IL-13 during infection of lung epithelial cells in vitro decreased the percentage of infected cells and reduced bacterial growth. Our results suggest that enhanced IL-13 responses in the airways, such as that found in asthmatics, may promote susceptibility to chlamydial lung infection. Importantly the role of IL-13 in regulating infection was not limited to the lung as we showed that IL-13 also promoted susceptibility to Cmu genital tract infection. Collectively our findings demonstrate that innate IL-13 release promotes infection that results in enhanced inflammation and have broad implications for the treatment of chlamydial infections and IL

HPV-11 and HPV-6 are the etiological agents of about 90 % of genital warts (GWs). The intra-typic variability of HPV-11 and its association with infection persistence and GW development remains undetermined. Here, HPV infection in men (HIM) participants who had an HPV-11 genital swab and/or GW, preceded or not by a normal skin genital swab were analysed. Genomic variants were characterized by PCR-sequencing and classified within lineages (A, B) and sublineages (A1, A2, A3, A4). HPV-11 A2 variants were the most frequently detected in the genital swab samples from controls and in both genital swabs and GW samples from cases. The same HPV-11 variant was detected in the GW sample and its preceding genital swab. There was a lack of association between any particular HPV-11 variant and the increased risk for GW development.

Men's genital arousal occurs in response to a limited number of sexual stimuli, whereas women's genital arousal occurs in response to a wide range of sexual stimuli, including those depicting nonpreferred cues. Researchers have hypothesized that women's nonspecific pattern of genital arousal prepares the body for sexual activity, thus functioning to protect the genital organs against injury. If this hypothesis is correct, women should show genital responses to any cues suggesting sexual activity, even unappealing cues that involve nonconsensual sex and extreme violence. Fifteen men and 15 women listened to fourteen 2-min audiotaped narratives that depicted an interaction between a man and a woman and that varied factorially according to the presence of consent, violence, and sexual activity. The results support the preparation hypothesis: Men showed the greatest genital arousal in response to narratives depicting consensual, nonviolent sex, whereas women showed similar responses to all the narratives involving sexual activities, including those describing a sexual assault.

Introduction Ano-Genital Warts (AGW) like other Sexually Transmitted Diseases (STD) is associated with Human Immunodeficiency Virus (HIV) infection. This study of AGW was done in HIV positive and HIV negative patients. Aim To study the risk factors and clinical presentations of ano-genital warts in HIV positive and negative patients. Materials and Methods A comparative, cross-sectional, descriptive study of 25 HIV positive and 25 HIV negative (n=50) AGW patients between 15-60 years of both sex was conducted in Dr. D. Y. Patil Hospital and Research Centre from July 2014 to July 2016. Results Significant association of HIV positivity (p<0.05) was observed between age group of 15-30 years and HIV negative status (p<0.05) in age group of 31-45 years. HIV positive status significantly higher in patients with self-admitted multiple sexual partners (p<0.01), homosexuality (p<0.05) and presentation with anal warts (p<0.01). HIV negative status correlated significantly with single sexual partner admission (p<0.01) and hetero-sexuality (p<0.05). Gender did not show significant association with number of sexual partners or HIV positivity. Extra-genital or only genital warts had no association with HIV status. Co-STDs though more in number in ser-positive group, did not show any significant association with HIV positivity (p>0.05). No patient presented with changes of malignancy. Four were adolescents below 19 years. Two patients had atypical presentations of giant condylomata i.e., Buschke-Lowenstein Tumour (BLT). Conclusion HIV positivity was significantly associated with the risk factors of age below 30 years, homo sexuality and multiple sexual partners. Anal warts were significantly common in HIV positive patients. Four adolescents with AGW underline the need for high risk behaviour counselling. No patient had malignant ano-genital warts. Follow up of these patients with Human Papilloma Virus (HPV) sub-typing is necessary. PMID:28274028

Limited data are available on the prevalence of genital mycoplasmas and Chlamydia trachomatis (CT) among Indian patients with genital tract infections. The objectives of the study were to determine the prevalence of Ureaplasma urealyticum (UU), Mycoplasma hominis (MH), Mycoplasma genitalium (MG), and CT in patients with genital tract infections. The antimicrobial susceptibilities of UU and MH were also assessed. Endocervical swabs/urethral swabs and first void urine samples of patients (n = 164) were collected. UU and MH were detected by culture and multiplex polymerase chain reaction (PCR). MG and CT were identified by PCR. Ureaplasma isolates were further biotyped and serotyped. Antimicrobial susceptibility was done by microbroth dilution method. UU, MH, MG, and CT were detected in 15.2%, 5.4%, 1.2%, and 6% patients, respectively. Ureaplasma parvum serovar 3/14 was the most prevalent. All isolates of UU and MH were uniformly susceptible to doxycycline and josamycin. Routine screening for these pathogens and antimicrobial susceptibility testing is warranted to prevent sequel of infections and formulate treatment guidelines.

Genital tract lacerations are responsible for potentially serious postpartum hemorrhage (PPH), and are often underestimated. The objective of this study was to analyze the characteristics of genital tract lacerations associated with severe PPH in a reference center. All women transferred for treatment of PPH due to genital tract lacerations between January 2008 and April 2011 were included in this observational study. Two populations of patients with genital tract lacerations were defined : patients with "complex" lesions and patients with "simple" genital tract laceration. Forty-four patients were treated for PPH associated with genital tract lacerations. The average age of patients was 30.6 years (17-41 years). All the patients had a vaginal delivery, combined with an instrumental in 70.5% of cases. With the exception of one patient, all patients had a revision of the cervix and vagina before the transport in our Institution. Twenty nine patients (70.7%) had received a suture of genital tract in their maternity. In our Hospital, the patient having a "simple" genital tract lesion received in 54.5% of cases medical drugs alone against 33.3% for patients with complex genital tract lacerations. In 39.4% of cases an embolization was necessary for the group of patients with complex genital tract lacerations against 9.1% in the simple genital tract lesion group. Genital tract lacerations are a serious cause of HDD. Their management should be multidisciplinary combining appropriate and timely decisions (resuscitation, embolization and/or surgery). The sequence of these treatments depends on the clinical condition of the patient and justifies a transfer to a referral center. Copyright © 2013. Published by Elsevier SAS.

Herpes simplex virus-2 (HSV-2) shedding episodes in humans vary markedly in duration and virologic titer within an infected person over time, an observation that is unexplained. To evaluate whether host or virological factors more closely accounted for this variability, we combined measures of viral replication and CD8+ lymphocyte density in genital biopsies, with a stochastic mathematical model of HSV-2 infection. Model simulations reproduced quantities of virus and duration of shedding detected in 1,003 episodes among 386 persons. In the simulations, local CD8+ lymphocyte density in the mucosa at episode onset predicted peak HSV DNA copy number and whether genital lesions or subclinical shedding occurred. High density of CD8+ T cells in the mucosa correlated with decreased infected cell lifespan and fewer infected epithelial cells before episode clearance. If infected cell lifespan increased by 15 min because of CD8+ lymphocyte decay, then there was potential for a thousandfold increase in the number of infected cells. The model suggests that the rate of containment of infected cells by the peripheral mucosal immune system is the major driver of duration and severity of HSV-2 reactivation in the immunocompetent host.

The genetic heterogeneity of melanomas and melanocytic nevi of the female genital tract is poorly understood. We aim to characterize the frequency of mutations of the following genes: BRAF, NRAS, KIT, GNA11, and GNAQ in female genital tract melanomas. We also characterize the frequency of BRAF mutations in female genital tract melanomas compared with melanocytic nevi. Mutational screening was performed on the following female genital tract melanocytic neoplasms: 25 melanomas, 7 benign melanocytic nevi, and 4 atypical melanocytic nevi. Of the 25 female genital tract melanoma specimens queried, KIT mutations were detected in 4 (16.0%), NRAS mutations in 4 (16.0%), and BRAF mutations in 2 (8.0%) samples. Two of the tumors with KIT mutations harbored double mutations in the same exon. No GNAQ or GNA11 mutations were identified among 11 melanomas screened. BRAF V600E mutations were detected in 7 of 7 benign melanocytic genital nevi (100%) and 3 of 4 atypical genital nevi (75%). Our study is limited by the small sample size of this rare subset of melanomas. KIT, NRAS, and BRAF mutations are found in a subset of female genital tract melanomas. Screening for oncogenic mutations is important for developing and applying clinical therapies for melanomas of the female genital tract. Copyright © 2014 American Academy of Dermatology, Inc.

This review presents and discusses the reasons for the currently employed anatomical terminology relating to the genital peritoneum of various domestic species, based upon its prenatal development. When reviewing the development of genital organs, attention must be paid to changes in the related peritoneum in order to define currently used terminology more clearly. The relevance of some terms such as Caudal genital ligament, Plica gubernaculi, Plica iguinalis and genital fold is considered. A system of serosal folds, the Plica gonadoinguinalis or genitoinguinalis, seems to be a useful term to be added to the Nomina Embryologica Veterinaria.

Cutaneous human papillomaviruses (HPVs) increase the risk of non-melanoma skin cancer in sun-exposed skin. We examined the role of beta-HPV in the development of male external genital lesions (EGLs), a sun-unexposed site. In this nested case-control study (67 men with pathologically-confirmed EGLs and 134 controls), exfoliated cells collected from the surface of lesions and normal genital skin 0, 6, and 12 months preceding EGL development were tested for beta-HPV DNA using a type-specific multiplex genotyping assay. Beta-HPV prevalence was estimated and conditional logistic regression was used to evaluate the association with condyloma, the most common EGL. While beta-HPV prevalence among controls remained stable, the prevalence among cases was lowest on the surface of lesion.

Primary heart tumors are rare, whereas metastatic heart tumors occur more frequently. We report a case of a 75-year-old Japanese woman who had metastatic heart tumors of the right ventricle. Although she initially received antibiotic therapy following a diagnosis of pneumonia and pleuritis, her symptoms worsened, and she developed dyspnea and bilateral lower limb edema. Echocardiography showed a huge mass lesion occupying the entire right ventricle. Because the patient's tumor markers were elevated, we used computed tomography to search for the primary lesion, which was located in the vagina or the uterus. Histology demonstrated the presence of basaloid squamous cell carcinoma in the vaginal tissue. Chemotherapy with paclitaxel and carboplatin was initiated. These data suggest that the tumor in the right ventricle metastasized from the genital organs.

An adult male Blainville's beaked whale (Mesoplodon densirostris) was found stranded on the Atlantic coast of the USA on 28 January 2004. Necropsy revealed a focal papilloma-like penile lesion, the cells from which revealed single 4-6 microm basophilic intranuclear inclusions. Total DNA extracted from lesion material was tested using a pan-herpes-virus PCR assay that targets the DNA polymerase gene and found to be positive. When the amplified DNA fragment was cloned, sequenced, and compared to GenBank-deposited herpesvirus DNA polymerase sequences, the detected virus was determined to be a distinct member of the Gammaherpesvirinae subfamily of herpesviruses. This new virus, tentatively named Ziphiid herpesvirus type 1, was associated with but not determined to be the cause of genital disease in the Blainville's beaked whale.

Fifteen patients with advanced or recurrent squamous-cell carcinoma of the cervix, vulva, vagina, and urethra were treated with simultaneous combination chemotherapy (5-fluorouracil infusion and mitomycin C) and radiotherapy (3,000 rad for a period of three weeks). Three to four weeks after completion of radiotherapy, 13 of 15 patients achieved partial or complete tumor shrinkage. Nine of 15 patients are alive, eight of whom (at a median follow-up time of 24 months) have no evidence of disease. The longest survival time was 45 + months. There was minimal toxicity associated with this therapy. The results of this pilot study suggest that the simultaneous administration of radiation and chemotherapy is an effective method of treatment of advanced female genital tract carcinoma.

We have evaluated a real-time PCR procedure based on the LightCycler technology for rapid detection of herpes simplex virus (HSV) in genital lesions. Two sets of primers, corresponding to the thymidine kinase and DNA polymerase regions, were used for the amplification reactions in separate capillaries containing the SYBR Green I dye as detection signal. In 28 of 118 samples (24%), HSV was isolated by conventional cell culture. All cell culture-positive samples were also positive by real-time PCR. Six additional cell culture-negative samples were positive by PCR with both sets of primers. Total processing time was less than 3 h. Real-time PCR using SYBR Green I as detection signal is a sensitive procedure for the rapid diagnosis of HSV in genital lesions. PMID:11880439

Introduction Some healthy males voluntarily seek castration without a recognized medical need. There are currently no standards of care for these individuals, which cause many of them to obtain surgery outside of a licensed medical setting. We seek to understand who performs these surgeries. Aim This study aims to characterize individuals who perform or assist in genital ablations outside of the healthcare system. Methods A cross-sectional Internet survey posted on eunuch.org received 2,871 responses. We identified individuals who had performed or assisted in human castrations (“cutters”; n = 98) and compared this group with all other survey respondents (n = 2,773), who had not assisted in castrations. Next we compared the cutters with the voluntary eunuchs. Lastly, because many of the cutters have themselves been castrated, we also divided the physically castrated population (n = 278) into cutters (n = 44) and noncutters (n = 234) and compared them. Main Outcome Measures Self-reported questionnaires were used to collect demographic information, gender identity and presentation, selected childhood experiences, and history of aggressive behaviors, self-harming behaviors, and hospitalization. Results Distinguishing characteristics of cutters included: (i) presenting themselves as very masculine, (ii) having had their longest sexual relationship with a man, (iii) growing up on a farm, (iv) witnessing animal castrations, (v) having a history of sexually inappropriate behavior, (vi) having been threatened with genital mutilation as a child, (vii) having a history of self-harm, (viii) being raised in a devoutly Christian household, (ix) having had an underground castration themselves, and (x) having body piercings and/or tattoos. Conclusions This study may help identify individuals who are at risk of performing illegal castrations. That information may help healthcare providers protect individuals with extreme castration ideations from injuring themselves or others

Etiology, transmission and protection: Herpes simplex virus-2 (HSV-2) is a leading cause of sexually transmitted infections with recurring manifestations throughout the lifetime of infected hosts. Currently no effective vaccines or prophylactics exist that provide complete protection or immunity from the virus, which is endemic throughout the world. Pathology/Symptomatology: Primary and recurrent infections result in lesions and inflammation around the genital area and the latter accounts for majority of genital herpes instances. Immunocompromised patients including neonates are susceptible to additional systemic infections including debilitating consequences of nervous system inflammation. Epidemiology, incidence and prevalence: More than 500 million people are infected worldwide and most reported cases involve the age groups between 16-40 years, which coincides with an increase in sexual activity among this age group. While these numbers are an estimate, the actual numbers may be underestimated as many people are asymptomatic or do not report the symptoms. Treatment and curability: Currently prescribed medications, mostly nucleoside analogs, only reduce the symptoms caused by an active infection, but do not eliminate the virus or reduce latency. Therefore, no cure exists against genital herpes and infected patients suffer from periodic recurrences of disease symptoms for their entire lives. Molecular mechanisms of infection: The last few decades have generated many new advances in our understanding of the mechanisms that drive HSV infection. The viral entry receptors such as nectin-1 and HVEM have been identified, cytoskeletal signaling and membrane structures such as filopodia have been directly implicated in viral entry, host motor proteins and their viral ligands have been shown to facilitate capsid transport and many host and HSV proteins have been identified that help with viral replication and pathogenesis. New understanding has emerged on the role of

Aim To determine whether immunotherapy with HPV6 L1 virus like particles (VLPs) without adjuvant (VLP immunotherapy) reduces recurrence of genital warts following destructive therapy. Trial design A randomized placebo controlled blinded study of treatment of recurrent genital warts amenable to destructive therapy, conducted independently in Australia and China. Methods Patients received conventional destructive therapy of all evident warts together with intramuscular administration of 1, 5 or 25 µg of VLP immunotherapy, or of placebo immunotherapy (0.9% NaCl), as immunotherapy at week 0 and week 4. Primary outcome, assessed at week 8, was recurrence of visible warts. Results Of 33 protocol compliant Brisbane recipients of placebo immunotherapy, 11 were disease free at two months, and a further 9 demonstrated reduction of > 50% in total wart area. Wart area reduction following destructive treatment correlated with prior duration of disease. Among 102 protocol compliant Brisbane recipients of VLP immunotherapy, disease reduction was significantly greater than among the placebo immunotherapy (50% ± s.e.m. 7%) recipients for subjects receiving 5 µg or 25 µg of VLP immunotherapy/dose (71% ± s.e.m.7%) but not for those receiving 1 µg VLP immunotherapy/dose (42% ± 7%). Of 52 protocol compliant placebo immunotherapy recipients in Wenzhou, 37 were disease free at two months, and a further 8 had > 50% disease reduction. Prior disease duration was much shorter in Wenzhou subject (8.1 ± 1.1 mo) than in Brisbane subjects (53.7 ± 5.5 mo). No significant reduction in mean wart area was observed for the 168 Wenzhou protocol compliant subjects who also received VLP immunotherapy. Conclusions This study confirms the findings in a previous open label trial that administration of VLP immunotherapy may assist in clearance of recurrent genital warts in patients for whom destructive therapy is unsuccessful and that unsuccessful destructive therapy is more common with increasing

Ultrastructural study of gonadal muscles in sea star, Asterina pectinifera, showed that myoepithelial cells were located only in the epithelial lining of the genital coelomic sinus. No myoepithelial cells were found in the visceral peritoneal epithelium or within connective tissue layer of the outer sac. Morphology of the myoepithelial cells in gonads of A. pectinifera varies during the reproductive cycle. During the gametogenic phase of the reproductive cycle, the myoepithelial cells get an elongated, spindle-like shape having a length of 20–30 m. In prespawning gonads, many of the myoepithelial cells form cytoplasmic extensions of 3–5 m in length, filled with myofilaments and penetrating into the underlying connective tissue of the outer sac or haemal sinus. Besides, myoepithelial cells, simultaneously anchored in the inner and outer sacs, were also observed. These changes result in development of more elaborated musculature and increase in contractility of the gonadal wall in prespawning gonads as compared to that during other stages of the reproductive cycle.

In this article, critical perspectives including postcolonial feminism, African feminism, and intersectionality are presented as having decolonizing methodological potential whereby the Western narrative surrounding the practice of female genital cutting, particularly in the context of migration, is reexamined. In addition, multiple intersecting influences on affected women's realities are accounted for and a critical consciousness that serves to inform praxis, address social determinants of health, and promote health equity is encouraged. The inclusion of an African feminist perspective, a traditionally marginalized critical perspective, serves to further decolonize some long-held erroneous beliefs about the sexuality, subjectivity, and embodiment of the African woman.

Tuberculosis is a disease with myriad presentations and manifestations; it can affect any organ or tissue, excluding only hair and nails. Doctors who are not familiar with extrapulmonary tuberculosis often overlook this disease. Urogenital tuberculosis (UGTB) is the second most common form of TB in countries with severe epidemic situation and the third most common form in regions with low incidence of TB. The term "Urogenital tuberculosis" includes kidney tuberculosis; male and female tuberculosis and urinary tract tuberculosis as complication of kidney tuberculosis. We describe rarest case of tuberculosis of a placenta in young woman, suffered from genital tuberculosis, which was overlooked before delivery, as well as typical tubo-ovarian tuberculomas.

Female genital mutilation/cutting (FGM/C) is a common harmful traditional practice in many communities in Africa and to a lesser extent in Middle East and other regions in the world. In order to better understand publishing on this topic, we conducted a bibliometric study on FGM/C. Bibliometric analyses can be used as an indicator of the extent of interaction of researchers, health authorities, and communities with a particular health issue. Scopus database was used to retrieve data on FGM/C. Keywords used were "female genital mutilation", "female genital circumcision", "female genital cutting" and "female circumcision". Specifically, the number of publications, top productive countries and institutions, highly cited articles, citation analysis, co-authorships, international collaboration, role of African countries, top active authors, and journals involved in publishing articles on FGM/C were reviewed and analyzed. We indirectly assessed the impact of publications using total number of citations received, average number of citations per article, Hirsch-index, percentage of highly cited articles, and journal's impact factor. One thousand and thirty-five publications on FGM/C were retrieved. The h-index of retrieved articles was 37. A steep rise in number of publications was noticed in mid-1990s and again in 2012. More than half of retrieved articles were published from 2006 - 2015. A total of 65 countries contributed. The top ten productive countries included ones from Northern America, Europe and Africa. Nigeria and Egypt were the most active African countries in FGM/C publications. At least nine African academic institutions were actively involved on FGM/C publications. Articles on FGM/C that received the highest number of citations were those that focused on negative physical and psychosexual consequences of FGM/C. Journal topic areas were obstetrics/gynecology, public health, and psychological sociology. Collaboration between African and European countries on
In 1973 approximately 1 million girls will be victimized by female genital mutilation (FGM), widely practiced in more than 20 African nations from Mauritania to the Ivory Coast in the west, to Egypt and North Tanzania in the east, as well as in Oman, Bahrain, North and South Yemen, and the United Arab Emirates. FGM takes place among the Moslem populations of the Philippines, Indonesia, and Malaysia and the Jewish Falashas in Ethiopia. FGM is practiced on babies just a few days old to girls right before marriage or young women pregnant with their first child. The most extreme mutilation is called infibulation. In Somalia, almost 100% of the women are infibulated, and so are more than 80% of the women in north and central Sudan. In Ethiopia/Eritrea, Mali, and Sierra Leone, 90% of the women have undergone some form of genital mutilation. The rate reaches 70% in Burkina Faso; 60% in Kenya, Gambia, and the Ivory Coast; and 50% in Senegal, Egypt, Guinea Bissau, and Nigeria. The mutilation often results in accumulation of menstrual blood and pelvic inflammatory disease often leading to infertility. Between 20% and 25% of infertility in Sudan has been attributed to female genital mutilation. The practice of FGM has existed for centuries, and some claim it originated in the Nile Valley during the Pharaonic era. On the other hand, Muslim countries like Iraq, Syria, and Tunisia do not practice FGM. The London Black Women's Health Action Project set up an educational network to prevent mutilations and to dispel the myth of religion about FGM. FORWARD convened the First Study Conference on Genital Mutilation of Girls in Europe in 1992 and deemed FGM a form of child abuse. Local campaigns in Africa, Asia, and the Arab world educate against FGM. The Inter-Africa Committee on Traditional Practices Affecting the Health of Women and Children, based in Addis Ababa, Ethiopia, has offices in more than 20 African nations to sensitize the public about the harmful effects of FGM.

Female genital mutilation (FGM) is a very ancient traditional and cultural ritual. Strategies and policies have been implemented to abandon this practice. However, despite commendable work, it is still prevalent, mainly in Muslim countries. FGM predates Islam. It is not mentioned in the Qur'an (the verbatim word of God in Islam). Muslim religious authorities agree that all types of mutilation, including FGM, are condemned. 'Sensitivity' to cultural traditions that erroneously associate FGM with Islam is misplaced. The principle of 'do no harm', endorsed by Islam, supersedes cultural practices, logically eliminating FGM from receiving any Islamic religious endorsement.

Plasma inhibitory factors, high levels of sex hormones, and depression of cell-mediated immunity may interfere with the natural host resistance to viral infections during pregnancy. It is apparent that hormonal, immunologic, and vascular changes in pregnancy may account for increased replication of herpes and for enhanced growth of condylomatous lesions. The challenge is to develop a rational plan of management for pregnant patients with herpes simplex or human papilloma virus infection. There has been a reevaluation of previous recommendations for the management of herpes in pregnancy. Although the consequences of neonatal infection are severe or fatal, the value of routine weekly screening is questionable. This regimen is a poor predictor of neonatal exposure to herpes since only one fourth of women shedding virus at the time of delivery can be identified by routine cultures. The mode of delivery should therefore be based on the presence or absence of lesions at the time of confinement. Cesarean section should be reserved for patients with lesions or with prodromal symptoms of recurrent disease at the time of delivery. Patients with ruptured membranes and active genital lesions should also be delivered by cesarean section. The spectrum of HPV-related diseases in pregnancy is poorly understood. Many questions remain unanswered. It may not be practical to treat very large or extensive genital warts during pregnancy. A cesarean section may be the best choice in these cases. It may be premature to recommend cesarean section for delivery of all pregnant women with symptomatic genital HPV infection. More data are needed. We recommend laser ablation of condylomatous lesions when discovered during pregnancy. Laser vaporization is associated with minimal morbidity when used by experienced surgeons. Trichloroacetic acid is excellent for minimal disease or for treatment of recurrences in pregnancy. Since the immune system seems to play an important role in control of viral

Here we reported two patients who presented with panuveitis and were transferred from ophthalmologists to rheumatologists, for both the patients had oral and genital ulcers. They were misdiagnosed with Behcet's disease at first glance. Two young males presented with acute uveitis with history of recurrent oral and genital ulcers. They initially presented with symptoms and signs resembling Behcet's disease and were treated with systemic steroids with suboptimal responses. Routine laboratory test revealed syphilis and human immunodeficiency virus (HIV) infection. After treatment of penicillin and anti HIV virus therapy, the panuveitis was relived. The other patient was lost in the follow up. Recently epidemiological data indicate that syphilis and HIV infection increase, which can mimic the manifestation of Behcet's disease. Diagnosis of sexual transmitted diseases, such as HIV or syphilis needs to be ruled out in all cases that mimic the clinical feature of Behcet's disease, especially for those who had a history of high risk behaviors. Every patient should have history analysis in detail. Screening of sexual transmitted diseases, such as HIV or syphilis is important especially in those rapid progressive panuveitis. Also, other virus infections, such as cytomegalovirus, epstein-barr virus or Herpes simplex virus can cause mucosa ulcers and uveitis. CD4 T cell count is a very important marker to indicate that the patient has immunodeficiency. Erythema nodosa and pseudofolliculitis are the third common clinical manifestation in Chinese Behcet's disease patients. Rheumatologist should watch out for patients without skin involvement when making the diagnosis of Behcet's disease. Syphilis-associated uveitis usually has a good prognosis. Treatment of antibiotics can get good response, 92% uveitis can be relieved, with 67% improved vision. Acute syphilitic posterior placoid chorioretinitis (ASPPC) is a clinically and angiographically distinct manifestation of ocular

We have shown that the spermicidal agent benzalkonium chloride can exert a direct inhibitory effect on the viral reverse transcriptase activity of human immunodeficiency virus type 1 (HIV-1) when utilized at concentrations of 0.05% and higher. Exposure of HIV-1 to this disinfectant at concentrations of more than 0.05% was able to completely destroy viral infectivity, as assessed on susceptible target cells. We have further shown that HIV-1, which is present in both seminal and genital secretions, can be inactivated in such fluids by direct exposure to benzalkonium chloride. PMID:1688873

To assess gender-specific impact of genital warts on health-related quality of life (HRQoL), and to explore to what extent sexual characteristics and clinical symptoms influenced the impact on emotional and sexual well-being of both sexes. We conducted a survey of sexual and clinical characteristics from persons diagnosed with genital warts at STI clinics. HRQoL was measured using two measurement tools: 1) the generic EQ-5D; and 2) the genital warts-specific CECA-10 including an emotional well-being and a sexual activity dimension. The EQ-5D scores were compared with scores of the general population. Descriptive analyses were used to explore characteristics associated with HRQoL scores stratified for gender. The HRQoL-measurement tools showed that genital warts have especially an emotional impact. The impact of genital warts on HRQoL was greater for women than for men. In addition, the CECA-10 showed that in women the impact of genital warts on sexual activity was influenced by age, relationship status and number of warts. No related factors were seen in men. Genital warts have a greater impact on women than on men. In women, sexual and clinical factors influenced the impact of genital warts on well-being, whereas in men no such factors were found.

Objective To describe the characteristics of pediatric genital injuries presenting to United States emergency departments (EDs). Methods A retrospective cohort study utilizing the U.S. Consumer Product Safety Commission (CPSC) National Electronic Injury Surveillance System (NEISS) from 1991-2010 to evaluate pediatric genital injuries was performed. Results Pediatric genital injuries represented 0.6% of all pediatric injuries with the incidence of injuries rising through the period studied, 1991-2010. The mean age at injury was 7.1 years old and was distributed 56.6% girls and 43.4% boys. A total of 43.3% had lacerations and 42.2% had contusions/abrasions. The majority of injuries occurred at home (65.9%), and the majority of patients (94.7%) were treated and released from the hospital. The most common consumer products associated with pediatric genital trauma were: bicycles (14.7% of all pediatric genital injuries), bathtubs (5.8%), daywear (5.6%), monkey bars (5.4%), and toilets (4.0%). Conclusion Although pediatric genital injuries represent a small proportion of overall injuries presenting to the ED, genital injuries continue to rise despite public health measures targeted to decrease childhood injury. Our results can be used to guide further prevention strategies for pediatric genital injury. PMID:23953603

Animal genitalia show two striking but incompletely understood evolutionary trends: a great evolutionary divergence in the shape of genitalic structures, and characteristic structural complexity. Both features are thought to result from sexual selection, but explicit comparative tests are hampered by the fact that it is difficult to quantify both morphological complexity and divergence in shape. We undertake a comparative study of multiple nongenitalic and male genital traits in a clade of 15 water strider species to quantify complexity and shape divergence. We show that genital structures are more complex and their shape more divergent among species than nongenital traits. Further, intromittent genital traits are more complex and have evolved more divergently than nonintromittent genital traits. More importantly, shape and complexity of nonintromittent genital traits show correlated evolution with indices of premating sexual selection and intromittent genital traits with postmating sexual selection, suggesting that the evolution of different components of genital morphology are shaped independently by distinct forms of sexual selection. Our quantitative results provide direct comparative support for the hypothesis that sexual selection is associated with morphological complexity in genitalic traits and highlight the importance of quantifying morphological shape and complexity, rather than size in studies of genital evolution. © 2011 The Author(s).

Background The objective of this study is to estimate the incidence of genital warts in Hong Kong and explore a way to establish a surveillance system for genital warts among the Hong Kong general population. Methods A total of 170 private doctors and all doctors working in the 5 local Social Hygiene Clinics (SHC) participated in this study. During the 14-day data collection period (January 5 through18, 2009), the participating doctors filled out a log-form on a daily basis to record the number of patients with genital warts. The total number of new cases of genital warts presented to private and public doctors in Hong Kong was projected using the stratification sampling method. Results A total of 721 (0.94%) adults presented with genital warts to the participating doctors during the two-week study period, amongst them 73 (10.1%) were new cases. The projected number of new cases of genital warts among Hong Kong adults was 442 (297 male and 144 female) during the study period. The incidence of genital warts in Hong Kong was estimated to be 203.7 per 100,000 person-years (respectively 292.2 and 124.9 per 100,000 person-years for males and females). Conclusions The incidence of genital warts is high among adults in Hong Kong. The study demonstrates the importance of collecting surveillance data from both private and public sectors. PMID:20849578

Three hundred and twenty-five consecutive live female deliveries at Nnamdi Azikiwe University Teaching Hospital, Nnewi were followed up for 9 months for evidence of any genital mutilation. Their mothers were examined for genital mutilation and a questionnaire based on face-to-face interview of the mothers was also administered. There was no genital mutilation observed among the 200 female babies whose mothers completed the 9 months follow up, The prevalence of genital mutilation among the mothers was 48%. The prevalence of female genital mutilation among the mothers increased with age. The circumcision index C.I. was zero and 3.0 at 16-20 years and 31-35 years age groups, respectively. Also the prevalence decreased with increasing level of education. The circumcision index was 1.0 for mothers at primary level education and least 0.33 at tertiary level of education. There was no relationship with parity. None of the mothers was willing to allow genital mutilation to be performed on her baby but 36% applied local treatment to the clitoris especially powder (28%). Dystocia was the commonest complication in the mothers and the knowledge about female genital mutilation was acquired informally from fellow women. Female education is paramount in the campaign and advocacy against female genital mutilation.

Female sexual arousal disorder is a pathophysiologic state characterized clinically by persistent or recurrent inability to attain or maintain an adequate lubrication-swelling response of sexual excitement until completion of sexual activity. Prior clinical experience with alprostadil products for men with erectile dysfunction supports its use in women with female sexual arousal disorder. To compare the effect of topical alprostadil with over-the-counter (OTC) lubricant on female genital arousal in the absence of visual sexual stimuli. Healthy premenopausal women without sexual dysfunction were recruited from the community to participate in the study. Of 17 women who consented, 10 were enrolled and completed the trial. The mean age of subjects was 32 years (range = 27-43). Study drug or placebo was applied topically to the genitals. Continuous temperature monitoring was performed. Participants completed questionnaires assessing genital sensation, effect, intensity, and duration. Change in temperature from baseline in vestibule, clitoris and vulva. In all 10 subjects, topical alprostadil induced a statistically significant increase in temperature of the vestibule, clitoris, and vulva compared with the OTC lubricant. The most rapid difference in genital temperature between placebo and alprostadil was seen on the vulva, which demonstrated a significant difference at approximately 9 minutes. There was a significant difference in temperature seen for the vestibule and clitoris at 11 and 19 minutes, respectively. Sixty percent of women reported being aware or conscious of genital sensations with topical alprostadil, but not with OTC lubricant. Discordance was noted in 30% of subjects who reported being aware or conscious of genital sensations with the two treatments and 10% who reported not being aware or conscious of genital sensations with either treatment. Topical alprostadil administered to healthy premenopausal women induced statistically significant, sustained

To explore men's knowledge of the negative consequences of female genital mutilation (FGM) to women's health in countries where this practice is performed. A qualitative methodology was used with an ethnomethodological approach. Both individual and group semi-structured interviews concerning FGM were conducted with 25 men, selected by triple sampling. A study presentation letter was provided to participants, together with an informed consent declaration. Permission was also procured to record the interviews in audio format. Data analysis was performed using the Atlas Ti7 software. Those participants against FGM are aware of the range of complications this practice can cause, being able to identify physical, obstetric, psychological, sexuality and social consequences in women subjected to FGM. However, those men who are in favour display a general ignorance of the problems resulting from this practice. Participants from countries where FGM is performed who are against this practice are more aware of the negative consequences than those who claim to be in favour. The design of awareness-raising programmes and other tools to combat female genital mutilation must highlight the implications for women's and girls' health, and include family-targeted campaigns which involve men in the process of eradicating this practice.

In Ethiopia, the Italian Association for Women in Development (AIDOS) has been working with Ethiopia's National Committee on Traditional Practices Affecting the Health of Women and Children for 5 years. AIDOS began working on female genital mutilation in the early 1980s and rejects charges of cultural imperialism that are applied to Northern organizations attempting to help African organizations address this violation of universal human rights. In Ethiopia, 85% of women are mutilated, with most undergoing Sunna, or removal of the prepuce of the clitoris. The joint project seeks to increase awareness about the health consequences of female genital mutilation in the target group. The primary technique used is provision of training of trainers courses and presentation of four modular units and audiovisual materials specifically designed for use with socially influential women, male and female secondary school students, community leaders, and health workers. In addition, an information/education campaign uses videos and sound and slide shows with accompanying story books. A second category of communication tools was developed for a mass information campaign, including radio spots, posters, information leaflets, and a newsletter. When the project was ready for expansion into the southern region of the country, it became clear that a new participatory communication strategy was required to stimulate discussion, such as the use of role playing and theater. Working together, the two organizations have successfully confronted project constraints such as the difficulty in assessing project impact, scheduling problems, and gender-biased assess to information.

Aims and method To study the mental health status of 66 genitally mutilated immigrant women originating from Africa (i.e. Somalia, Sudan, Eritrea and Sierra Leone). Scores on standardised questionnaires (Harvard Trauma Questionnaire-30, Hopkins Symptom Checklist-25, COPE-Easy, Lowlands Acculturation Scale) and demographic and psychosocial correlates were analysed. Results A third of the respondents reported scores above the cut-off for affective or anxiety disorders; scores indicative for post-traumatic stress disorder were presented by 17.5% of women. Type of circumcision (infibulation), recollection of the event (a vivid memory), coping style (avoidance, in particular substance misuse) and employment status (lack of income) were significantly associated with psychopathology. Clinical implications A considerable minority group, characterised by infibulated women who have a vivid memory of the circumcision and cope with their symptoms in an avoidant way, reports to experience severe consequences of genital circumcision. In terms of public healthcare, interventions should target these groups as a priority. PMID:26755984

Analysis of 240 consecutive vaginal swabs using the compatibility profile technique revealed that only 2 bacteria have the ability to be a sole isolate and as such a candidate to be a major aerobic regulator of the bacterial flora of the female genital tract (BFFGT). Compatibility profiles of Lactobacillus and Gardnerella vaginalis have shown that these organisms shared compatibility profiling for the majority of the normal bacterial constituents of the female genital tract. Dominance disruption appears to come from the addition of compatible co-isolates and presumed loss of numerical superiority. These phenomena appear to be the keys to reregulation of BFFGT. Lactobacillus appears to be the major regulator of both G. vaginalis and anaerobic bacteria. When additional organisms are added to the bacterial flora, they may add to or partially negate the inhibitory influence of Lactobacillus on the BFFGT. Inhibitor interrelationships appear to exist between coagulase-negative staphylococci and Staphylococcus aureus and the group B streptococci (GBS) and other beta hemolytic streptococci. Facilitating interrelationships appear to exist between S. aureus and the GBS and selected Enterobacteriaceae. PMID:18476156

About 100 million women are estimated to be circumcised globally. Various rates of complications have been encountered, especially after circumcision, such as bleeding, infection, shock, menstrual irregularity, difficulty in urination or common urinary tract infections, inguinal pain, difficulty in sexual intercourse, and genital circumcision scar especially at the vulvar region, and cystic or solid character mass in short and long term. Furthermore, the maternal-fetal morbidity and mortality increase due to bleeding and fistula, which develop after prolonged labor, travail, and difficult labors. Our aim in this paper was to discuss a 42-year-old multiparous female case who had undergone type 2 radical genital mutilation (circumcision) when she was 7 years of age, along with the literature, which has been evaluated for the gradually growing mass at the left inguinal canal region in the last 10 years and diagnosed as epidermoid inclusion cyst developing secondary to postcircumcision surgical ground trauma, since there was no other case found in the literature search that had been circumcised at such an early age and developing after circumcision at such advanced age, and, therefore, this is suggested to be the first case on this subject.

The practice of female genital cutting (FGC) is widespread in Nigeria and varies from one ethnic group to another. In 1994, Nigeria joined members of the 47th World Health Assembly in a resolution to eliminate the practice, and since then, several steps has been taken to achieve this objective. Nigeria joined members of the 47th World Health Assembly sixteen years ago in a resolution to eliminate female genital mutilation. This study uses data from 420 women aged 15?49 years who had at least one surviving daughter to investigate changes in FGC prevalence among mothers and daughters. The sample was systematically selected through stratified random sampling across the six states of southwest Nigeria. Focus group discussion, and an in-depth interview with fourteen women considered to be specialist in FGC were also held to compliment data generated from the interview. The analysis indicated an FGC prevalence rate of 75% and 71% for mothers and daughters, respectively. It further indicated that the practice is rooted in tradition despite the fact that 52% of the respondents are aware of the health hazards of FGC. Educated mothers were found to be less likely to favor the cutting of their daughters. It is suggested that educational campaigns aimed toward parents should be intensified. Legal recourse, prohibition of operations, improvement in women's status, and sex education are also suggested as means of eradicating the practice.

Several studies are reported which examine the critical stimuli and responses as well as personality factors important in genital exhibitionism. Using penile volume measurement, sex history questionnaires, personality tests, and behavioral observations, it was found that (1) exhibitionists responded most to mature females and were comparable to normals in reactions to children and men; (2) while exhibitionists indicated narcissistic desires in exposing, in a laboratory study they did not differ from controls in reactions to exposing with various reactions of the female, from sexual arousal and admiration to fear and anger; (3) the only strong features distinguishing exhibitionists from controls and other sexually anomalous subjects were peeping associated with orgasm and outdoor solitary masturbation; (4) exhibitionists seemed to be less assertive and less feminine than controls, but results were weak and inconsistent; (5) exhibitionists and controls did not differ in separation and divorce or marital satisfaction; (6) blood testosterone and penile reactivity of exhibitionists were within normal limits. Overall, the results suggest that most major theories of genital exhibitionism are wanting. It is suggested that narcissism and pedophilia be examined further in connection with exhibitionism.

The aim of this study was to verify human papillomavirus (HPV) transmission and genotype concordance among heterosexual couples. Thirty-one married couples were evaluated. All male subjects presented with clinically diagnosed HPV-related malignant or potentially malignant lesions and underwent peniscopy and penile swab. Their female counterparts underwent swabs of the uterine cervix and oral mucosa. HPV-DNA detection was performed by polymerase chain reaction and restriction fragment length polymorphism. HPV-DNA was detected in the penis, vagina/cervix, and oral cavity of 16 couples (51.61%). Of these, HPV-DNA concordance was observed in 14 couples (87.5%). HPV-DNA was amplified in penile and oral sites of 14 couples. Of these, 13 couples reported fellatio (92.85%), most of them (10 couples, 76.9%) without condom use. HPV-DNA concordance was observed in 7/10 of these couples (70%). The three couples (100%) who reported use of condom during fellatio were HPV-DNA discordant (p = 0.025). Lifetime number of female sexual partners and detection of HPV-DNA in the penile mucosa are surrogate markers of exposure to HPV during marriage. Consistent use of condoms may reduce the risk of HPV transmission. Oral acquisition of HPV from oro-genital contact is influenced by lack of condom use and previous sexual behavior of the male partner. In addition, oral transmission of the virus due to fellatio is as common as genital transmission.

Human papillomavirus (HPV) is one of the most common sexually transmitted infections worldwide. Most HPV infections are cleared within two years by the immune system. Only in 5% to 10% of infected women the infection persists determining a high risk of developing cervical intraepithelial neoplasia. The transfer factor (TF) or dialyzable leukocyte extract is an immunomodulator that has been successfully used as an adjuvant in the treatment of intracelular infections such as recurrent herpes virus diseases. One daily dose of transfer factor was given for five days and subsequently each week for five weeks to a group of women with persistent genital papillomavirus infection. We included 13 patients, aged 19 to 45 years, with first intercourse between the ages of 14 to 23, and a mean of three sexual partners in their lifetime. All of them had persistent HPV that had been treated before with local and ablative therapeutic options, including cervical freezing, cervical conization, cauterizing loop, imiquimod and podophyllin. Transfer factor was administered daily for 5 days, and subsequently at 7-day intervals for 5 weeks. We found a clinical significant improvement in the gynaecological evaluation of cervical, vaginal, vulvar and perineal lesions. No recurrences have developed for at least 1 year of follow-up. The use of transfer factor in women with HPV showed resolution of genital lesions, without recurrences for at least one year after the treatment was ended.
The ritual genital mutilation of females is widely practiced across the greater part of the African continent affecting an estimated 100 million women in more than 25 countries. The practice also exists to a lesser extent along the Arab peninsula and in parts of Asia. Approximately 200,000 immigrants have come to the US over the past decade from such countries. Many of the women among this immigrant population are severely disabled by social constraints, chronic pain, and impaired mobility. They only rarely present, however, at conventional medical facilities because they are prevented by men and/or they do not expect their specialized medical problems to be understood or handled compassionately. The author spent 32 months between 1979 and 1984 in Sudan, Kenya, and Egypt researching female genital mutilation. She describes the immediate and long-term medical consequences of the process and condition, especially with regard to menstruation and childbirth. The significance of the procedure as a social phenomenon is explained in historical terms and in terms of the values of the societies in which it is established, with consideration given to how a working relationship may be established with the immigrant women.

Male genitalia often show remarkable differences among related species in size, shape and complexity. Across poeciliid fishes, the elongated fin (gonopodium) that males use to inseminate females ranges from 18 to 53% of body length. Relative genital size therefore varies greatly among species. In contrast, there is often tight within-species allometric scaling, which suggests strong selection against genital–body size combinations that deviate from a species' natural line of allometry. We tested this constraint by artificially selecting on the allometric intercept, creating lines of males with relatively longer or shorter gonopodia than occur naturally for a given body size in mosquitofish, Gambusia holbrooki. We show that relative genital length is heritable and diverged 7.6–8.9% between our up-selected and down-selected lines, with correlated changes in body shape. However, deviation from the natural line of allometry does not affect male success in assays of attractiveness, swimming performance and, crucially, reproductive success (paternity). PMID:27188478

Female genital mutilation (FGM) is a traditional cultural practice, but also a form of violence against girls, which affects their lives as adult women. FGM comprises a wide range of procedures: the excision of the prepuce; the partial or total excision of the clitoris (clitoridectomy) and labia; or the stitching and narrowing of the vaginal orifice (infibulation). The number of girls and women who have been subjected to FGM is estimated at around 137 million worldwide and 2 million girls per year are considered at risk. Most females who have undergone mutilation live in 28 African countries. Globalization and international migration have brought an increased presence of circumcised women in Europe and developed countries. Healthcare specialists need to be made aware and trained in the physical, psychosexual, and cultural aspects and effects of FGM and in the response to the needs of genitally mutilated women. Health education programs targeted at immigrant communities should include information on sexuality, FGM, and reproduction. Moreover, healthcare workers should both discourage women from performing FGM on their daughters and receive information on codes of conduct and existing laws. The aim is the total eradication of all forms of FGM.
Valacyclovir, the metabolic precursor of acyclovir, is now approved for treatment and prevention of genital infection with herpes simplex viruses. The clinical file is bulky and methodologically sound. For treatment of a first episode of genital herpes, a large comparative trial has shown that valacyclovir (1 g twice a day) is as effective as acyclovir (200 mg five times a day) when given for 10 days. For treating recurrences, two trials show that valacyclovir is as effective as acyclovir (200 mg five times a day) with a treatment period of 5 days. A daily dose of 1 g of valacyclovir is as effective as 2 g daily. Valacyclovir can be administered once a day. For prevention among patients with frequent recurrences, the efficacy of valacyclovir (500 mg/d in a single dose) has been proven in a placebo-controlled trial lasting 4 months. In these trials, valacyclovir and acyclovir were both well tolerated, with no major differences between the two drugs. PMID:10424269

Objective: To identify factors which determine whether and when patients will disclose infection with genital herpes to sexual partners. Methods: The sample was 26 women and 24 men attending a herpes clinic in a sexually transmitted disease clinic. Semistructured interviews yielded quantitative data and also qualitative data which were subjected to content analysis. Results: Characteristics of partners were very important in determining whether disclosure occurred. Respondents were less likely to tell partners regarded as casual. Perception of the likely reaction of partners was important in deciding whether to tell. Many respondents assumed that they were not infectious if they were not currently having an attack or if they were taking antiviral medication. The decision whether to tell tended to be based on considerations of likely discovery and of honesty towards the partner rather than control of transmission. Of patient characteristics only self rated depressed mood was related to disclosure to the most recent partner. Conclusions: Perception of the partner and anticipated partner response is crucially important in determining whether and when disclosure of genital herpes infection occurs. PMID:12576613

We examined the post-embryonic development of the male and female genital apparatus of the brown spider, Loxosceles intermedia. The development of the genital apparatus for both sexes begins with the appearance of inner structures. In the male genital apparatus, formation of the testes occurs first, followed by differentiation of the duct, ampulla and vas deferens, and finally the formation of the genital opening and differentiation of the copulatory organ (secondary sexual characteristic). Similarly, the development of the female genital apparatus begins with the formation of the ovaries, followed by the appearance of oocytes in vitellogenesis, then the development of oviducts and uterus internus and, finally, the spermatheca. These data may be very important in further comparative studies on the development of the reproductive system of spiders.

In human genital skin the majority of superficial sensory corpuscles is represented by glomerular corpuscles. These corpuscles show an own morphology. Our aim is to compare the ultra-structure of superficial sensory corpuscles in the penis skin of younger and older subjects. In this report the ultra-structure of the sensitive corpuscle in the penis skin of the younger and older subjects was compared, showing that the genital skin of the older humans contains more simple complexes than the younger ones. Our findings support the view that the age-related changes that can be observed in human glomerular genital corpuscles are consistent with an increase of the simple complexes and a strong decrease of the poly-lamellar one in the older people. These findings demonstrate that human genital corpuscles underwent age-related changes. Moreover our morphological findings can be correlated in relation to the clinical evolution of the sensitivity in the genital skin.
Genital surgery is one of the most controversial and contested practices, yet it is frequently described and referred to with little or no attention to cultural and social context. This article examines the practice, performed on both men and women, and the extent to which it clashes with issues of consent and capacity, as well as multicultural concepts of toleration for minority group practices. It then questions why female genital surgery, unlike male genital surgery, is legally prohibited in Australia. It argues that such legal gender bias stems from a liberal conception of "tolerance" and the limits of consent in Australia, placing female genital surgery in an "unacceptable" category and male genital surgery in an "acceptable" category.

Neurodevelopmental disorders may have their origins during intrauterine development. We used a well-defined animal model to test whether hematogenous infection with genital mycoplasma would alter the expression of genes associated with autism spectrum disorders (ASD). In a preliminary experiment, rats were exposed at 14 days gestation (GD14) to Mycoplasma pulmonis or sterile broth and sacrificed at GD18. Infection and inflammation status of the pups was ascertained by culture and cytokine ELISA. Intra-cardiac injection of 10(6)CFU M. pulmonis resulted in amniotic infection of 100% of the pups and was accompanied by higher levels of IL-1β in amniotic fluids. In a second experiment, animals were infected in a similar manner but dams and their litters were sacrificed at GD18, GD21 or postpartum day 3 (PPD3). Expression of proinflammatory cytokines and neurodevelopmental genes in the fetal brains was evaluated. M. pulmonis infection significantly increased the expression of IL-1β, TNF-α and COX-2 in fetal and neonatal brains. Expression of GFAP and CD11b, markers for activation on astrocytes and microglial cells, respectively, was also increased for infected animals. M. pulmonis significantly increased SHANK-3 gene expression at GD21 and PPD3 and PCP-2 expression at GD21. No effect of M. pulmonis infection on Reelin, PTEN, BDNF or HGF was detected. These data suggest that M. pulmonis infection at GD14 increases the expression of proinflammatory genes in the perinatal brain. Further studies with earlier time-points of infection and ones that use behavioral outcomes are needed to better understand the potential role of genital mycoplasmosis on pychopathology.

The significant morbidities of ectopic pregnancy and infertility observed in women after Chlamydia trachomatis genital infection result from ascension of the bacteria from the endocervix to the oviduct, where an overly aggressive inflammatory response leads to chronic scarring and Fallopian tube obstruction. A vaccine to prevent chlamydia-induced disease is urgently needed. An important question for vaccine development is whether sterilizing immunity at the level of the oviduct is essential for protection because of the possibility that a chlamydial component drives a deleterious anamnestic T cell response upon oviduct reinfection. We show that mice inoculated with attenuated plasmid-cured strains of Chlamydia muridarum are protected from oviduct pathology upon challenge with wild-type C. muridarum Nigg despite induction of a response that did not prevent reinfection of the oviduct. Interestingly, repeated abbreviated infections with Nigg also elicited recall responses that protected the oviduct from pathology despite low-level reinfection of this vulnerable tissue site. Challenged mice displayed significant decreases in tissue infiltration of inflammatory leukocytes with marked reductions in frequencies of neutrophils but significant increases in frequencies of CD4 Th1 and CD8 T cells. An anamnestic antibody response was also detected. These data indicate that exposure to a live attenuated chlamydial vaccine or repeated abbreviated genital infection with virulent chlamydiae promotes anamnestic antibody and T cell responses that protect the oviduct from pathology despite a lack of sterilizing immunity at the site.

Type I interferon (IFN) interferes with virus replication, promotes antiviral responses, and controls innate and adaptive immune responses to certain viruses. Recently, we reported that 2'-5' oligoadenylate synthetase-like 1 (OASL1) negatively regulates type I IFN production by inhibiting the translation of the type I IFN-regulating master transcription factor, IRF7. Notably, while OASL1-deficient mice induce robust production of type I IFN and are resistant to systemic viral infection, the effects of OASL1 during localized viral infection has not been studied. To this end, we investigated the role of OASL1 during mucosal HSV-2 infection of the genital tract. Oasl1(-/-) mice exhibited better survival rates than wild type (WT) mice following intravaginal HSV-2 infection, and suppressed virus replication more efficiently despite comparable recruitment of effector immune cells. Moreover, Ly6C(high) monocytes, and not pDCs or other cell types, displayed enhanced production of type I IFNs in Oasl1(-/-) mice in response to HSV-2 infection. Furthermore, cytotoxic T cell responses including IFN-γ production were accelerated in Oasl1(-/-) mice after mucosal HSV-2 infection. Collectively, these results demonstrate that OASL1 deficiency promotes antiviral immunity against local mucosal viral infection and suggest that OASL1 could be a therapeutic target for treatment of HSV-2 infection of the genital mucosa.

Herpes simplex virus-2 (HSV-2) is a chronic reactivating infection that leads to recurrent shedding episodes in the genital tract. A minority of episodes are prolonged, and associated with development of painful ulcers. However, currently, available tools poorly predict viral trajectories and timing of reactivations in infected individuals. We employed principal components analysis (PCA) and singular value decomposition (SVD) to interpret HSV-2 genital tract shedding time series data, as well as simulation output from a stochastic spatial mathematical model. Empirical and model-derived, time-series data gathered over >30 days consists of multiple complex episodes that could not be reduced to a manageable number of descriptive features with PCA and SVD. However, single HSV-2 shedding episodes, even those with prolonged duration and complex morphologies consisting of multiple erratic peaks, were consistently described using a maximum of four dominant features. Modeled and clinical episodes had equivalent distributions of dominant features, implying similar dynamics in real and simulated episodes. We applied linear discriminant analysis (LDA) to simulation output and identified that local immune cell density at the viral reactivation site had a predictive effect on episode duration, though longer term shedding suggested chaotic dynamics and could not be predicted based on spatial patterns of immune cell density. These findings suggest that HSV-2 shedding patterns within an individual are impossible to predict over weeks or months, and that even highly complex single HSV-2 episodes can only be partially predicted based on spatial distribution of immune cell density.

BACKGROUND The dermoscopic features of vulvar melanosis lesions are well known. To our knowledge, there are only a few case reports about dermoscopic features of pigmented genital lesions in male patients. OBJECTIVE To evaluate dermoscopic and clinical characteristics of benign lesions of the genital area in both males and females, and to assess the distinguishing dermoscopic criteria of vulvar melanosis and atypical melanocytic nevi of the genital type. METHODS 68 patients with pigmented genital lesions were included in this observational study (28 male and 40 female). A punch biopsy was taken from all pigmented lesions and histopathological examination was performed on all specimens. RESULTS We histopathologically diagnosed: genital melanosis in 40 lesions, atypical melanocytic nevi of the genital type in 15 lesions, melanocytic nevi in 9 lesions, seborrheic keratosis in 4 lesions. The most frequent locations were the glans penis (19 patients, 67.9%) in males and the labia minora (19 patients, 47.5%) in females. The mean age of patients with atypical nevi (28,6 ± 11,36) was significantly lower than the mean age of patients with genital melanosis (47,07 ± 15,33). CONCLUSIONS Parallel pattern is prominent in genital melanosis, ring-like pattern is only observed in genital melanosis. Most pigmented lesions on the genital area are solitary. Blue-white veil and irregular dots are only observed in AMNGT. According to these results, we propose that histopathological examination is performed, especially if blue-white veil and irregular dots are found by dermoscopy. PMID:25830986

Studies on HIV acquisition and transmission in women exposed to sexual trauma throughout their life cycle are lacking but some findings suggest that rates of HIV acquisition through coercive sex are significantly higher than that seen in consensual sex. Sexual trauma can also occur as a result of female genital mutilation, which makes sex extremely painful and can cause increased abrasions, lacerations and inflammation, which enhances the risk of HIV acquisition. This review presents an overview of the immune system in the human female reproductive tract from adolescence, through puberty to pregnancy and menopause. What is clear is that the foundation of information on immune protection in the female reproductive tract throughout the life cycle of women is extremely limited and at some stages such as adolescence and menopause are grossly lacking. Against this back backdrop, forced or coercive sexual intercourse as well as genital mutilation further complicates our understanding of the biological risk factors that can result in transmission of HIV and other sexually transmitted infections.

Vaginal bacterial communities play an important role in human health and have been shown to influence HIV infection. Pigtailed macaques (Macaca nemestrina) are used as an animal model of HIV vaginal infection of women. Since the bacterial microbiota could influence retrovirus infection of pigtailed macaques, the genital microbiota in 10 cycling macaques was determined by pyrosequencing. The microbiota of all macaques was polymicrobial with a median of 13 distinct genera. Strikingly, the genera Sneathia and Fusobacterium, both in the phylum Fusobacteria, accounted for 18.9% and 13.3% of sequences while the next most frequent were Prevotella (5.6%), Porphyromonas (4.1%), Atopobium (3.6%), and Parvimonas (2.6%). Sequences corresponding to Lactobacillus comprised only 2.2% of sequences on average and were essentially all L. amylovorus. Longitudinal sampling of the 10 macaques over an 8-week period, which spanned at least one full ovulatory cycle, showed a generally stable presence of the major types of bacteria with some exceptions. These studies show that the microbiota of the pigtailed macaques is substantially dissimilar to that found in most healthy humans, where the genital microbiota is usually dominated by Lactobacillus sp. The polymicrobial makeup of the macaque bacterial populations, the paucity of lactobacilli, and the specific types of bacteria present suggest that the pigtailed macaque microbiota could influence vaginal retrovirus infection.

Background. Combination antiretroviral therapy (cART) reduces genital tract human immunodeficiency virus type 1 (HIV-1) load and reduces the risk of sexual transmission, but little is known about the efficacy of cART for decreasing genital tract viral load (GTVL) and differences in sex or HIV-1 subtype. Methods. HIV-1 RNA from blood plasma, seminal plasma, or cervical wicks was quantified at baseline and at weeks 48 and 96 after entry in a randomized clinical trial of 3 cART regimens. Results. One hundred fifty-eight men and 170 women from 7 countries were studied (men: 55% subtype B and 45% subtype C; women: 24% subtype B and 76% subtype C). Despite similar baseline CD4+ cell counts and blood plasma viral loads, women with subtype C had the highest GTVL (median, 5.1 log10 copies/mL) compared to women with subtype B and men with subtype C or B (4.0, 4.0, and 3.8 log10 copies/mL, respectively; P < .001). The proportion of participants with a GTVL below the lower limit of quantification (LLQ) at week 48 (90%) and week 96 (90%) was increased compared to baseline (16%; P < .001 at both times). Women were significantly less likely to have GTVL below the LLQ compared to men (84% vs 94% at week 48, P = .006; 84% vs 97% at week 96, P = .002), despite a more sensitive assay for seminal plasma than for cervical wicks. No difference in GTVL response across the 3 cART regimens was detected. Conclusions. The female genital tract may serve as a reservoir of persistent HIV-1 replication during cART and affect the use of cART to prevent sexual and perinatal transmission of HIV-1. PMID:23532477

Objective To describe the natural history of genital warts and vulvar intraepithelial neoplasia (VIN) in women with human immunodeficiency virus (HIV). Methods A cohort of 2,791 HIV infected and 953 uninfected women followed for up to 13 years had genital examinations at 6-month intervals, with biopsy for lesions suspicious for VIN. Results The prevalence of warts was 4.4% (5.3% for HIV seropositive women and 1.9% for seronegative women, P < 0.0001). The cumulative incidence of warts was 33% (95% C.I. 30, 36%) in HIV seropositive and 9% (95% C.I. 6, 12%) in seronegative women (P < 0.0001). In multivariable analysis, lower CD4 lymphocyte count, younger age, and current smoking were strongly associated with risk for incident warts. Among 501 HIV seropositive and 43 seronegative women, warts regressed in 410 (82%) seropositive and 41 (95%) seronegative women (P = 0.02), most in the first year after diagnosis. In multivariable analysis, regression was negatively associated with HIV status and lower CD4 count as well as older age. Incident VIN of any grade occurred more frequently among HIV seropositive than seronegative women: 0.42 (0.33 – 0.53) vs 0.07 (0.02 – 0.18)/100 person-years (P < 0.0001). VIN2+ was found in 58 women (55 with and 3 without HIV, P < 0.001). Two women with HIV developed stage IB squamous cell vulvar cancers. Conclusion While genital warts and VIN are more common among HIV seropositive than seronegative women, wart regression is common even in women with HIV, and cancers are infrequent. PMID:21934446
The accessory glands in the genital tract of female Acheta domesticus L. (Orthoptera: Gryllidae) were investigated in detail. The glands are situated within the 7th and 8th abdominal segment and lead to the genital chamber lateral to the terminal papilla of the ductus receptaculi. The shape of the gland is characterized by a complex system of tubules, including numerous ramifications. The gland's size ranges from 2 to 4 mm. The epithelium is constructed according to a simple scheme and consists of a cuticular intima at the luminal side, one layer of gland cells, and a basallamina at the outermost side. The observed morphology of the accessory glands widely corresponds with that in other cricket species (e.g., Teleogryllus commodus). This is also true for the structure of a single gland cell, which can be subdivided into a basal part with nucleus and intracellular cisternae, as well as an apical part with all those compartments responsible for the production of the secretion. The secretion itself may be classified as lipophilic and is produced for the first time 4 to 6 days after the imaginai moult. Several endogenic functions of the secretion are discussed (lubricant for oviposition, support for introducing the tube of the spermatophore into the ductus receptaculi, etc.). PMID:23425229

Problem High-risk human papillomavirus (HR-HPV) is prevalent in HIV-infected women and may be associated with mucosal changes that promote HIV replication. Method of Study Innate immune molecules, antimicrobial activity, HIV RNA, and HPV DNA genotypes were measured in a cross-sectional study of 128 HIV-infected women categorized into HPV-16 (n=8), other HR-HPV (n=41), and non-HR-HPV controls (n=79). Results Compared to controls, HR-HPV groups had higher plasma viral loads (p=0.004), lower CD4 cells (p=0.02), more genital tract HIV RNA (p=0.03), greater number of different HPV types (p<0.001), higher cervicovaginal lavage (CVL) IL-1α (p=0.03) and human beta defensin 2 (HBD2) (p=0.049), and less anti-HIVBal activity (p=0.03). HPV-16 remained significantly associated with higher HBD2 (p=0.03), higher IL-1α (p=0.009), and lower anti-HIVBaL activity (p=0.03) compared to controls after adjusting for plasma viral load and CD4 T cell count. Conclusion HR-HPV is associated with mucosal changes in HIV-infected women that could adversely impact genital tract health. PMID:26685115

Genital coevolution between the sexes is expected to be common because of the direct interaction between male and female genitalia during copulation. Here we review the diverse mechanisms of genital coevolution that include natural selection, female mate choice, male-male competition, and how their interactions generate sexual conflict that can lead to sexually antagonistic coevolution. Natural selection on genital morphology will result in size coevolution to allow for copulation to be mechanically possible, even as other features of genitalia may reflect the action of other mechanisms of selection. Genital coevolution is explicitly predicted by at least three mechanisms of genital evolution: lock and key to prevent hybridization, female choice, and sexual conflict. Although some good examples exist in support of each of these mechanisms, more data on quantitative female genital variation and studies of functional morphology during copulation are needed to understand more general patterns. A combination of different approaches is required to continue to advance our understanding of genital coevolution. Knowledge of the ecology and behavior of the studied species combined with functional morphology, quantitative morphological tools, experimental manipulation, and experimental evolution have been provided in the best-studied species, all of which are invertebrates. Therefore, attention to vertebrates in any of these areas is badly needed. Copyright © 2015 Cold Spring Harbor Laboratory Press; all rights reserved.

Current treatment of genital herpes is focused on ameliorating signs and symptoms but is not curative. However, as potential herpes simplex virus (HSV) cure approaches are tested in the laboratory, we aimed to assess the interest in such studies by persons with genital herpes and the willingness to assume risks associated with experimental therapy. We constructed an anonymous online questionnaire that was posted on websites that provide information regarding genital herpes. The questions collected demographic and clinical information on adults who self-reported as having genital herpes, and assessed attitudes toward and willingness to participate in HSV cure clinical research. Seven hundred eleven participants provided sufficient responses to be included in the analysis. Sixty-six percent were women; the median age was 37 years, and the median time since genital HSV diagnosis was 4.7 years. The willingness to participate in trials increased from 59.0% in phase 1 to 68.5% in phase 2, and 81.2% in phase 3 trials, and 40% reported willingness to participate even in the absence of immediate, personal benefits. The most desirable outcome was the elimination of risk for transmission to sex partner or neonate. The mean perceived severity of receiving a diagnosis of genital HSV-2 was 4.2 on a scale of 1 to 5. Despite suppressive therapy available, persons with genital herpes are interested in participating in clinical research aimed at curing HSV, especially in more advanced stages of development.

According to several sources, little progress is being made in eliminating the cutting of female genitalia. This paper, based on qualitative interviews and observations, explores perceptions of female genital cutting and elimination of the phenomenon in Hargeisa, Somaliland. Two main groups of participants were interviewed: (1) 22 representatives of organisations whose work directly relates to female genital cutting; and (2) 16 individuals representing different groups of society. It was found that there is an increasing use of medical staff and equipment when a girl undergoes the procedure of female genital cutting; the use of terminology is crucial in understanding current perceptions of female genital cutting; religion is both an important barrier and facilitator of elimination; and finally, traditional gender structures are currently being challenged in Hargeisa. The findings of this study suggest that it is important to consider current perceptions on practices of female genital cutting and on abandonment of female genital cutting, in order to gain useful knowledge on the issue of elimination. The study concludes that elimination of female genital cutting is a multifaceted process which is constantly negotiated in a diversity of social settings.

The current study was aimed at comparing genital and subjective sexual arousal in pre- and postmenopausal women and exploring the effects of heightened sympathetic nervous system (SNS) activity on these parameters. Seventy-one women (25 young and premenopausal, 25 postmenopausal, and 21 age-matched premenopausal women) participated in two counterbalanced sessions consisting of genital arousal assessment with vaginal photoplethysmography and subjective arousal assessment with self-report questionnaires. SNS activity was enhanced using laboratory-induced hyperventilation. Results demonstrated no significant differences between pre- and postmenopausal women on genital and subjective measures of arousal in response to neutral and erotic films. SNS manipulation increased genital excitement only in young, premenopausal women. These data suggest that prior SNS enhancement can differentiate pre- from postmenopausal genital arousal. Data also revealed significant correlations between genital and subjective sexual arousal in older pre- and postmenopausal women, but not in young premenopausal women. These data are the first to directly compare genital-subjective correlations between pre- and postmenopausal women.

Background Our goal in the present study was to investigate the prevalence and correlates of genital warts in a population of female sex workers in Mombasa, Kenya. Because of the high prevalence of HIV-1 in this population, we were particularly interested in the association between HIV-1 infection and genital warts. Methods We conducted a cross-sectional study of the prevalence and correlates of genital warts among high-risk women in Mombasa, Kenya. Between 2001 and 2007, 1182 women were enrolled, of whom 613 (51.4%) were HIV-1-seropositive. Chi square tests and logistic regression were used to examine the associations between genital warts and potential correlates. Results Genital warts were identified on clinical examination in 27 (2.3%) women. Women who were HIV-1-seropositive were nearly 8 times as likely to have genital warts compared to HIV-1-seronegative women (OR 7.69, 95% CI 2.30–25.6). Conclusion Understanding the prevalence and correlates of genital warts will help to determine whether coverage for the wart-inducing subtypes 6 and 11 in an HPV vaccine is an important consideration in resource-limited countries.

To assess the effectiveness of the HPV vaccines in preventing genital warts in young women. Population-based study using health databases. Valencian Community (Spain). All girls and women aged 14-19years who were registered in the Valencian Community between January 2009 and December 2014 (n=279,787). Incident cases of genital warts were defined as the first activation of diagnosis code ICD-9-CM 078.11 (Condyloma acuminatum) in primary care and outpatient clinics during the study period. There were 612 cases of genital warts. The overall incidence rate was 75.8/100,000 person-years (95% CrI 69.7-81.8). There was a decrease in genital warts when female candidates to be vaccinated with quadrivalent HPV vaccine reached the age of 18 (in 2012), compared to previous years. Incidence of genital warts in unvaccinated women and those who received the bivalent vaccine was higher than in girls and women who received the quadrivalent HPV vaccine. The effectiveness of a three-dose regimen of the quadrivalent HPV vaccine was 77% (95 CrI: 66-85%), whereas that of a single dose was 61% (95 CrI: 20-87%). No effectiveness was seen with a full vaccination course with the bivalent HPV vaccine. Three doses of the quadrivalent HPV vaccine were effective against genital warts in our population. Moreover, with low vaccine coverage the incidence of genital warts decreased only in the vaccinated. Copyright © 2017 Elsevier Ltd. All rights reserved.

The role of sexual selection in fuelling genital evolution is becoming increasingly apparent from comparative studies revealing interspecific divergence in male genitalia and evolutionary associations between male and female genital traits. Despite this, we know little about intraspecific variance in male genital morphology, or how male and female reproductive traits covary among divergent populations. Here we address both topics using natural populations of the guppy, Poecilia reticulata, a livebearing fish that exhibits divergent patterns of male sexual behaviour among populations. Initially, we performed a series of mating trials on a single population to examine the relationship between the morphology of the male's copulatory organ (the gonopodium) and the success of forced matings. Using a combination of linear measurements and geometric morphometrics, we found that variation in the length and shape of the gonopodium predicted the success of forced matings in terms of the rate of genital contacts and insemination success, respectively. We then looked for geographical divergence in these traits, since the relative frequency of forced matings tends to be greater in high-predation populations. We found consistent patterns of variation in male genital size and shape in relation to the level of predation, and corresponding patterns of (co)variation in female genital morphology. Together, these data enable us to draw tentative conclusions about the underlying selective pressures causing correlated patterns of divergence in male and female genital traits, which point to a role for sexually antagonistic selection.

Herpes simplex virus types 1 and 2 are the main cause of genital ulcers worldwide. Although herpes simplex virus type 2 is the major cause of genital lesions, herpes simplex virus type 1 accounts for half of new cases in developed countries. Herpes simplex virus type 2 seroprevalence rises with sexual activity from adolescence through adulthood. Slovenian data in a high-risk population shows 16% seroprevalence of HSV-2. HSV-1 and HSV-2 DNA in genital swabs was detected in 19% and 20.7%, respectively. In most cases, genital herpes is asymptomatic. Primary genital infection with herpes simplex virus types 1 and 2 can be manifested by a severe clinical picture, involving the vesicular skin and mucosal changes and ulcerative lesions of the vulva, vagina, and cervix in women and in the genital regi
