    Considerable progress has been made in the field of pediatric uroradiology, as in most other aspects of radiology, since the last edition of this text was published in 1978. To a large extent, this progress was due to the remarkable advances in, and an increased application of, ultrasound, computed tomography, and nuclear imaging. In this section, an attempt has been made to incorporate and illustrate some of the applications of these diagnostic modalities to pediatric urology. The subjects discussed in this section include a brief account of the major radiologic procedures used in pediatric urology, followed by a review of the most common congenital and acquired diseases of the urinary tract and of the male and female genital tract, precocious puberty and intersex conditions, and disorders of the adrenal glands and related structures

    We studied the relationships of selected microbes and the role of consorts in the causation of vaginal discharge which may be due to cervicitis or vaginitis. A total of 93 consecutive patients in the reproductive age group with symptoms of vaginal discharge along with their sexual partners were studied. Samples were collected from the cervix and posterior fornix of the female patients and from the urethra and sub-prepucial area of the male partner for culture of Neisseria gonorrhoeae, Gardnerella vaginalis, Mycoplasma hominis, ureaplasma, candida, aerobic and anaerobic organisms. Apart from cultures, KOH and Gram stain of the discharge were made. Predominant pathogen isolated was Ureaplasma urealyticum from 40 (43.01%) females and 23 (24.7%) males. The next common pathogenic organisms isolated were candida species from 11 (11.8%) females and 5 (5.4%) males and Chlamydia trachomatis in 3 (3.2%) females and 1 (1.1%) male. Various organisms were more frequently isolated from the 29 of 43 (67.4%) couples who had had sexual intercourse 7 days prior to the recruitment as compared to 14 of 43 (32.6%) who had had coitus more than 7 days prior to their recruitment. This may be due to the spontaneous disappearance or decrease in the number of organisms to the level that they could be detected by culture. In our study, 6 (6.5%) of male partners carrying pathogenic organisms were asymptomatic, indicating that their screening and treatment is vital.

    This is an overview of the current applications of magnetic resonance imaging (MRI) in the genitourinary tract based on the experience with the 0.5-Tesla MR scanner (Gyroscan, Philips) at the Leiden University Hospital and on reports in the literature. MRI appears to share some of the limitations of CT. MRI cannot reliably differentiate between a malignant and a benign tumor. In the staging of ovarian malignancies by means of MRI, bowel preparation would be desirable. On the other hand, the soft-tissue contrast resolution of MRI is superior to that of CT and images can be obtained in any plane. Thus MRI promises to be an accurate method for staging malignancies. The results in the examination of transplant kidneys are encouraging. It is expected that there will be a place for MRI as a complementary technique to ultrasonography in the diagnosis of scrotal disease. (Auth.)

    Malignant neoplasms of the genitourinary (GU) tract account for a significant number of cancer-related deaths in man. For example, prostate cancer is the third leading cause of cancer-related death in adult males. Early diagnosis and treatment can have a profound effect on patient prognosis and survival. This paper examines the large body of information related to primary tumors of the kidney, bladder, and prostate, and their pattern of spread. Tumor oncology is discussed and related to the utility of available techniques, such as CT, MR imaging, and US. Imaging strategies are discussed that stress consideration of therapeutic efficacy and patient outcome. Current tumor staging and classification is presented and the various imaging strategies keyed to detection, definition, and treatment options for GU tract tumors. The strengths and limitations of modern imaging techniques are reviewed. An optimal approach to effective workup is developed with regard to availability, evolving technology, and cost efficacy. The controversies and conflicts in imaging and treatment options are explored while constructing a step-by-step approach that is both flexible and pragmatic for the clinician and radiologist faced daily with oncologic management choices

    The endocrine system and genitourinary tract unite in various syndromes. Genitourinary malignancies may cause paraneoplastic endocrine syndromes by secreting hormonal substances. These entities include Cushing`s syndrome, hypercalcemia, hyperglycemia, polycythemia, hypertension, and inappropriate ADH or HCG production. The most important syndromic scenarios that links these two systems are hereditary renal cancer syndromes with specific genotype/phenotype correlation. There are also some very rare entities in which endocrine and genitourinary systems are involved such as Carney complex, congenital adrenal hyperplasia and Beckwith-Wiedemann syndrome. We will review all the syndromes regarding manifestations present in endocrine and genitourinary organs.

    Full Text Available Abstract Objective: The abnormalities of the genitourinary tract development are the leading cause of chronic kidney disease (CKD in children. The diagnosis of this disease in Brazil is late and incomplete, which results in increased morbidity and mortality in this age group. Early diagnosis of this condition is the prerogative of generalist pediatricians, and the aim of this study was to review the clinical signs and symptoms associated with developmental abnormalities of the genitourinary tract. Data sources: Based on the description of a symbolic clinical case, the authors conducted a non-systematic review of medical literature. Data synthesis: The results suggest that the following data should be used as a warning for early diagnosis of affected children: (a combined urinary tract abnormalities (chromosomal abnormalities; sequence of malformations [VACTERLand Prune-Belly]; and musculoskeletal, digestive tract, heart, and nervous system malformations; (b previous history (congenital anomalies of the kidney and urinary tract [CAKUT] in the family, low birth weight, and oligoamnios; (c clinical signs (polyuria/nocturia, urinary tract infection, systemic arterial hypertension, failure to thrive, weak urinary stream, difficulty to start urination, distended bladder, non-monosymptomatic enuresis, urinary/urge incontinence, and bowel and bladder dysfunction; and (d pre- and postnatal ultrasonographic alterations (increased anteroposterior diameter of the renal pelvis, mainly in the third trimester of pregnancy; single kidney; hydronephrosis associated with other abnormalities; and hydronephrosis with parenchymal involvement in the post-neonatal assessment. Conclusion: The suggestions shown here can help the pediatrician to establish clinical hypotheses for the early diagnosis of developmental abnormalities of the genitourinary tract without resorting to expensive and invasive procedures.

    The major use of radionuclide cystography is in the management of children with vesicoureteral reflux (VUR). Reflux is common, occurring in one-third to one-half of children with urinary tract infection. The significance of VUR lies in its associated symptoms and consequences, which include impaired renal growth and function, vague ill health, renal pain, and more importantly the development of reflux nephropathy, a significant cause of end-stage renal disease and hypertension in children. Although reflux may resolve spontaneously, particularly milder degrees of reflux, the age at which this may occur is unpredictable and repeated follow-up cystography over a number of years may be necessary. Therefore, it is important to minimize radiation to the child while providing accurate diagnostic information. This paper discusses how the technique of radionuclide cystography compares favorably with routine contrast voiding cystourethrography (VCUG) in these respects, and in addition can provide quantitative information not obtained by radiographic techniques. Other indications may include screening siblings of patients known to have reflux, follow-up of antireflux surgery and occasionally screening for reflux in children who have had urinary tract infection

    Full Text Available A 91-year-old female presented with lower extremity swelling and shortness of breath. Laboratory analysis revealed elevations in blood urea nitrogen and creatinine along with microscopic hematuria on urinalysis. Computed tomography imaging showed moderate right hydronephrosis with dilatation of the proximal ureter with a soft tissue density at a transition point. Endoscopic evaluation revealed multiple raised, fleshy, and hemorrhagic masses throughout the bladder which are present in both ureters. Biopsy of these lesions revealed malignant melanoma invading the lamina propria. No dermatologic lesions were identified suggesting a primary malignant melanoma of the genitourinary system.

    Full Text Available IgG4-related disease (IgG4-RD is a recently established albeit well recognized fibro-inflammatory condition with distinctive features including a characteristic histopathological appearance; a propensity to develop tumefactive lesions in multiple body sites; and oft elevated serum IgG4 levels. The consensus statement on IgG-4 RD equips practicing pathologists with a set of working guidelines for the diagnosis of pathologic lesions identified in a host of different organ system affected with this disease. The diagnosis of IgG4-RD requires the combined presence of the characteristic histopathological appearance and increased numbers of IgG4-positive plasma cells. The essential histopathological features include a dense lymphoplasmacytic infiltrate, a storiform pattern of fibrosis, and obliterative phlebitis. Tissue IgG4-positive plasma cell counts and IgG4: IgG ratios are significant ancillary aids in establishing the diagnosis. The spectrum of IgG4-RD continues to expand and involve multiple body sites. The genitourinary system comprising of the kidneys, ureters, urinary bladder, urethra, prostate gland, testes and penis is one of the multiple organ systems to be affected by IgG4-RD. This review describes the clinical and histopathologic patterns of involvement of the genitourinary system by IgG4-RD, in association with serologic and radiological features.

    A primary goal of this review is to try to increase the reader's understanding of several clinical problems that present primarily in children. A second goal is to increase the reader's understanding of the applicability of nuclear cystography with manometry and the practical as well as potential aspects of testicular and varicocele imaging, while providing sufficient reference material to facilitate further study in specific areas of interest. If these goals are achieved, then the authors final goal, an increased awareness and utilization of these techniques by clinicians, can be accomplished by interested and convinced colleagues. A major portion of this review focuses on nuclear cystography, in particular, its role in the evaluation of patients with known urinary tract infections, patients with known or suspected vesicoureteral reflux who are siblings of patients with vesicoureteral reflux, and patients with neurogenic bladder in general and myelo-meningocele in particular. Attention is given to the association of GU tract anomalies with gastrointestinal tract anomalies, focusing on imperforate anus as a common example. Testicular imaging, in its conventional mode for evaluating the acute, painful scrotum, is presented, but, in addition, radionuclide venography to detect varicoceles are reviewed. Whereas this technique has been used in the investigation of male infertility, it appears to have considerable potential for assessment of adolescent males with asymptomatic, swollen testicals or those with evidence of testicular atrophy

    Cataloguing gene expression during development of the genitourinary tract will increase our understanding not only of this process but also of congenital defects and disease affecting this organ system. We have developed a high-resolution ontology with which to describe the subcompartments of the developing murine genitourinary tract. This ontology incorporates what can be defined histologically and begins to encompass other structures and cell types already identified at the molecular level. The ontology is being used to annotate in situ hybridisation data generated as part of the Genitourinary Development Molecular Anatomy Project (GUDMAP), a publicly available data resource on gene and protein expression during genitourinary development. The GUDMAP ontology encompasses Theiler stage (TS) 17 to 27 of development as well as the sexually mature adult. It has been written as a partonomic, text-based, hierarchical ontology that, for the embryological stages, has been developed as a high-resolution expansion of the existing Edinburgh Mouse Atlas Project (EMAP) ontology. It also includes group terms for well-characterised structural and/or functional units comprising several sub-structures, such as the nephron and juxtaglomerular complex. Each term has been assigned a unique identification number. Synonyms have been used to improve the success of query searching and maintain wherever possible existing EMAP terms relating to this organ system. We describe here the principles and structure of the ontology and provide representative diagrammatic, histological, and whole mount and section RNA in situ hybridisation images to clarify the terms used within the ontology. Visual examples of how terms appear in different specimen types are also provided. PMID:17452023

    This chapter is concerned with cancers of the cervix uteri, the corpus uteri, the ovary, vulva, and vagina. Radiotherapy has an important place in the management of patients with cancers of the genital tract but the radiotherapist must collaborate closely with surgical colleagues, both gynaecological and urological. Each must appreciate the merits and limitations of surgery and radiation therapy, whether used alone or in combination, with curative intent or in a supportive role

    Conclusion: Our study demonstrated that the main risk factors for PTL were vaginal infection with T. vaginalis, M. hominis, coryneforms, and Gram-negative bacilli, and their determinants (vaginal pH>5, positive whiff test, heavy vaginal bleeding. Both young age (< 20 years and poor obstetric history were also the risk factors. Therefore, screening for genitourinary tract infections is strongly recommended to be included in prenatal care.

    Full Text Available Tuberculosis (TB remains a worldwide scourge and its incidence appears to be increasing due to various factors, such as the spread of human immunodeficiency virus (HIV and acquired immunodeficiency syndrome (AIDS. The insidious onset and non-specific constitutional symptoms of genitourinary tuberculosis (GUTB often lead to delayed diagnosis and rapid progression to a non-functioning kidney. Due to hematogenous dissemination of TB, there is a potential risk of involvement of the contralateral kidney too. Imaging plays an important role in the making of a timely diagnosis and in the planning of treatment, and thus helps to avoid complications such as renal failure. Imaging of GUTB still remains a challenge, mainly on account of the dearth of literature, especially related to the use of the newer modalities such as magnetic resonance imaging (MRI. This two-part article is a comprehensive review of the epidemiology, pathophysiology, and imaging findings in renal TB. Various imaging features of GUTB are outlined, from the pathognomonic lobar calcification on plain film, to finer early changes such as loss of calyceal sharpness and papillary necrosis on intravenous urography (IVU; to uneven caliectasis and urothelial thickening, in the absence of renal pelvic dilatation, as well as the hitherto unreported ′lobar caseation′ on ultrasonography (USG. Well-known complications of GUTB such as sinus tracts, fistulae and amyloidosis are described, along with the relatively less well-known complications such as tuberculous interstitial nephritis (TIN, which may remain hidden because of its ′culture negative′ nature and thus lead to renal failure. The second part of the article reviews the computed tomography (CT and MRI features of GUTB and touches upon future imaging techniques along with imaging of TB in transplant recipients and in immunocompromised patients.

    Genitourinary tuberculosis is a disease spread hematogenously from a small tuberculous abscess of the lung. The renal cortex is initially involved, and multiple granulomas form. Ultimately the cortex may cavitate and communicate with the collecting system, allowing downward extension of the infection and subsequent focal caliectasis with infundibular stenosis, ureteral fibrosis, and calcifications of urinary tract organs. The female genitourinary organ is also infected by the hematogenous spread of tuberculosis, the most common lesion being hydrosalpynx with salpingitis. The clinical and radiologic features of genitourinary tuberculosis may mimic other acute abdominal diseases, and the diagnosis of tuberculosis remains difficult. This report describes the ways in which computed tomography and magnetic resonance imaging are valuable aids in the recognition and diagnosis of genitourinary tuberculosis. (author)

    Female genital tract, which includes oviduct, uterus, and vagina, is critical for female reproduction. In recent years, animal experiments using knockout mice and genetic studies on patients with female genital malformations have contributed substantially to our understanding of the molecular mechanisms in the female genital tract development. Here we review genes that are involved in various stages of female genital tract formation and development.

    In this report, we describe a urethritis case caused by C. glucuronolyticum in a 37-year-old, apparently healthy male, who complained mild pain in the lower abdomen, with several urinary symptoms. While urethral and semen specimens did not yield positive results for microbiological evaluation, cultures of urine samples revealed the monomicrobial growth on blood-containing media of tiny colonies after 24 h of incubation, clearly evident only after 48 h of incubation under CO2-enriched atmosphere. Colonies were identified as C. glucuronolyticum both by matrix-assisted laser desorption ionization-time of flight (MALDI-TOF and 16S rRNA gene sequencing. Oral ciprofloxacin gradually led to clinical improvement and, finally, to a complete recovery, in accordance with microbiological findings. In spite of its infrequent detection, C. glucuronolyticum might be a potential urogenital pathogen in males more commonly that what believed, perhaps due to slow growth leading to underrecognition; we suggest therefore to consider the organism in the differential diagnostics of bacterial diseases of the urinary tract.

    A correct classification of malformations of the female genital tract is essential to prevent unnecessary and inadequate surgical operations and to compare reproductive results. An ideal classification system should be based on aetiopathogenesis and should suggest the appropriate therapeutic strategy. We conducted a systematic review of relevant articles found in PubMed, Scopus, Scirus and ISI webknowledge, and analysis of historical collections of 'female genital malformations' and 'classifications'. Of 124 full-text articles assessed for eligibility, 64 were included because they contained original general, partial or modified classifications. All the existing classifications were analysed and grouped. The unification of terms and concepts was also analysed. Traditionally, malformations of the female genital tract have been catalogued and classified as Müllerian malformations due to agenesis, lack of fusion, the absence of resorption and lack of posterior development of the Müllerian ducts. The American Fertility Society classification of the late 1980s included seven basic groups of malformations also considering the Müllerian development and the relationship of the malformations to fertility. Other classifications are based on different aspects: functional, defects in vertical fusion, embryological or anatomical (Vagina, Cervix, Uterus, Adnex and Associated Malformation: VCUAM classification). However, an embryological-clinical classification system seems to be the most appropriate. Accepting the need for a new classification system of genitourinary malformations that considers the experience gained from the application of the current classification systems, the aetiopathogenesis and that also suggests the appropriate treatment, we proposed an update of our embryological-clinical classification as a new system with six groups of female genitourinary anomalies.

    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.

    Full Text Available Background: Tuberculosis (TB is still a major worldwide concern. There is no pathognomonic clinical feature or imaging findings for definite diagnosis of extra pulmonary TB. Therefore, TB involvement of Gastrointestinal or Genitourinary tract can be easily confused with peritoneal carcinomatosis and advanced ovarian carcinoma. Our aim is to emphasize the importance of considering the disease based upon the epidemiologic clues of the patients, while interpreting the positive results for a suspicious ovarian malignancy. Cases: This paper illustrates 8 cases of ovarian or peritoneal tuberculosis, whose initial diagnoses were malignant processes of the GU tract. Conclusion: Tuberculosis ( TB should be always being considered in the differential diagnosis of advanced ovarian cancer, especially in the regions that are endemic for the disease.

    Full Text Available It is well known that adipose tissue can influence puberty, sexual maturation, and fertility in different species. Adipose tissue secretes molecules called adipokines which most likely have an endocrine effect on reproductive function. It has been revealed over the last few years that adipokines are functionally implicated at all levels of the reproductive axis including the gonad and hypothalamic-pituitary axis. Many studies have shown the presence and the role of the adipokines and their receptors in the female reproductive tract of different species. These adipokines regulate ovarian steroidogenesis, oocyte maturation, and embryo development. They are also present in the uterus and placenta where they could create a favorable environment for embryonic implantation and play a key role in maternal-fetal metabolism communication and gestation. Reproductive functions are strongly dependent on energy balance, and thereby metabolic abnormalities can lead to the development of some pathophysiologies such as polycystic ovary syndrome (PCOS. Adipokines could be a link between reproduction and energy metabolism and could partly explain some infertility related to obesity or PCOS.

    Approximately half of preterm births are attributable to maternal infections, which are commonly undetected and untreated in low-income settings. Our primary aim is to determine the impact of early pregnancy screening and treatment of maternal genitourinary tract infections on the incidence of preterm live birth in Sylhet, Bangladesh. We will also assess the effect on other adverse pregnancy outcomes, including preterm birth (stillbirth and live birth), late miscarriage, maternal morbidity, and early onset neonatal sepsis. We are conducting a cluster randomized controlled trial that will enroll 10,000 pregnant women in Sylhet district in rural northeastern Bangladesh. Twenty-four clusters, each with ~4000 population (120 pregnant women/year) and served by a community health worker (CHW), are randomized to: 1) the control arm, which provides routine antenatal and postnatal home-based care, or 2) the intervention arm, which includes routine antenatal and postnatal home-based care plus screening and treatment of pregnant women between 13 and 19 weeks of gestation for abnormal vaginal flora (AVF) and urinary tract infection (UTI). CHWs conduct monthly pregnancy surveillance, make 2 antenatal and 4 postnatal home visits for all enrolled pregnant women and newborns, and refer mothers or newborns with symptoms of serious illness to the government sub-district hospital. In the intervention clusters, CHWs perform home-based screening of AVF and UTI. Self-collected vaginal swabs are plated on slides, which are Gram stained and Nugent scored. Women with AVF (Nugent score ≥4) are treated with oral clindamycin, rescreened and retreated, if needed, after 3 weeks. Urine culture is performed and UTI treated with nitrofurantoin. Repeat urine culture is performed after 1 week for test of cure. Gestational age is determined by maternal report of last menstrual period at study enrollment using prospectively completed study calendars, and in a subset by early (pregnancy outcomes

    Conclusions: Foreign body insertion to lower urinary tract was rare. A main cause for insertion of foreign bodies was autoerotism, misconceptions regarding masturbation, and underlying psychiatric illness. In addition to suitable method of surgical removal, counseling and psychiatric evaluation are necessary to prevent recurrences or for early detection of psychiatric problems.

    Uncomplicated Urinary tract infections are common in adult women across the entire age spectrum, with mean annual incidence of 15% and 10% in those aged 15-39 and 40-79 years, respectively. Urinary tract infection (UTI), with its diverse clinical syndromes and affected host groups, remains one of the most common but widely misunderstood and challenging infectious diseases encountered in clinical practice. Recurrent urinary tract infections (UTIs) present a significant problem for women and a challenge for the doctors who care for them. The diagnosis of uncomplicated UTI can be achieved best by a thorough assessment of patient symptoms with or without the addition of a urine dipstick test. Treatment should be based on the most recent guidelines, taking into account resistance patterns in the local community. The patient who suffers from recurrent UTIs can be treated safely and effectively with continuous antibiotic prophylaxis, post-coital therapy, or self-initiated treatment. This review article covers the latest trends in the management of recurrent UTI among women. Further research is needed regarding rapid diagnosis of UTI, accurate presumptive identification of patients with resistant pathogens, and development of new antimicrobials for drug-resistant UTI.

    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.

    Kaei Nasu M.D., Ph.D.

    2008-01-01

    Full Text Available Tamoxifen is widely used for endocrine treatment and breast cancer prevention. It acts as both an estrogen antagonist in breast tissue and an estrogen agonist in the female lower genital tract. Tamoxifen causes severe gynecologic side effects, such as endometrial cancer. This review focuses on the effects of prolonged tamoxifen treatment on the human female genital tract and considers its tumorigenicity in the gynecologic organs through clinical data analysis. Tamoxifen is associated with an increased incidence of benign endometrial lesions such as polyps and hyperplasia and a two- to four-fold increased risk of endometrial cancer in postmenopausal patients. Moreover, the incidence of functional ovarian cysts is significantly high in premenopausal tamoxifen users. To prevent tamoxifen from having severe side effects in gynecologic organs, frequent gynecological examination should be performed for both premenopausal and postmenopausal patients with breast cancer who are treated with this drug.

    The purpose of this article is to review the late effects of cancer therapy on the female reproductive tract. The anatomic sites detailed are the vulva, vagina, cervix, uterus, fallopian tubes, and ovaries. The available pathophysiology is discussed. Clinical syndromes are presented. Tolerance doses of irradiation for late effects are rarely presented in the literature and are reviewed where available. Management strategies for surgical, radiotherapeutic, and chemotherapeutic late effects are discussed. Endpoints for evaluation of therapeutic late effects have been formulated utilizing the symptoms, objective, management, and analytic (SOMA) format. Late effects on the female reproductive tract from cancer therapy should be recognized and managed appropriately. A grading system for these effects is presented. Endpoints for late effects and tolls for the evaluation need to be further developed

    2017-09-01

    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.

    To describe pattern of female genital tract cancers seen at Olabisi Onabanjo University Teaching Hospital (OOUTH), Sagamu, Nigeria. This is a retrospective review of all cases of female genital tract cancers managed at the Gynaecology department of OOUTH, Sagamu, Nigeria. OOUTH is a tertiary health institution of the State's university and it takes referrals from within and outside the State. Case records of all female genital tract cancers managed between January 2004 and December 2013 were retrieved and analysed using SPSS version 16.0. There were 2059 women treated forvarious gynaecologic conditions, 179 (8.7%) were cases of female genital tract cancers and 161 records were available for analysis. Cervical cancer constituted the commonest (51.6%), followed by ovarian (35.4%), endometrial (9.9%), and choriocarcinoma (1.9%). There were no cases of vaginal and fallopian tube cancers. The lowest mean age was found in choriocarcinoma (36.60 ± 4.50 years) and highest in vulvar cancer (70.00 ± 2.82 years). The mean ages for cervical, endometrial and ovarian cancers were (51.98 ± 12.39), (65.38 ± 7.24), and (54.42 ± 10.51) years respectively. Similarly the least mean parity was found in choriocarcinoma (2.33 ± 1.52), and the highest in vulvar cancer (6.00 ± 1.44). The mean parity for cervical, endometrial, and ovarian were (4.10 ± 1.49),(3.06 ± 1.48), and (3.72 ± 1.68) respectively. These differences are statistically significant, age; F = 7.61, p < 0.0001, and parity; F = 3.27, p= 0.013. Incidence of cervical, endometrial, and ovarian cancers remain high and presentations are at late stages. There is a need to improve on cervical cancer screening, and for the attending physicians to improve on their indices of suspicions as regards endometrial and ovarian cancers.

    Heinonen, Pentti K

    2016-11-01

    This study assessed the distribution of Müllerian duct anomalies in two verified classifications of female genital tract malformations, and the presence of associated renal defects. 621 women with confirmed female genital tract anomalies were retrospectively grouped under the European (ESHRE/ESGE) and the American (AFS) classification. The diagnosis of uterine malformation was based on findings in hysterosalpingography, two-dimensional ultrasonography, endoscopies, laparotomy, cesarean section and magnetic resonance imaging in 97.3% of cases. Renal status was determined in 378 patients, including 5 with normal uterus and vagina. The European classification covered all 621 women studied. Uterine anomalies without cervical or vaginal anomaly were found in 302 (48.6%) patients. Uterine anomaly was associated with vaginal anomaly in 45.2%, and vaginal anomaly alone was found in 26 (4.2%) cases. Septate uterus was the most common (49.1%) of all genital tract anomalies, followed by bicorporeal uteri (18.2%). The American classification covered 590 (95%) out of the 621 women with genital tract anomalies. The American system did not take into account vaginal anomalies in 170 (34.7%) and cervical anomalies in 174 (35.5%) out of 490 cases with uterine malformations. Renal abnormalities were found in 71 (18.8%) out of 378 women, unilateral renal agenesis being the most common defect (12.2%), also found in 4 women without Müllerian duct anomaly. The European classification sufficiently covered uterine and vaginal abnormalities. The distribution of the main uterine anomalies was equal in both classifications. The American system missed cervical and vaginal anomalies associated with uterine anomalies. Evaluation of renal system is recommended for all patients with genital tract anomalies.

  2. Adhesion Molecules Associated with Female Genital Tract Infection.

    Directory of Open Access Journals (Sweden)

    Jamal Qualai

    Full Text Available Efforts to develop vaccines that can elicit mucosal immune responses in the female genital tract against sexually transmitted infections have been hampered by an inability to measure immune responses in these tissues. The differential expression of adhesion molecules is known to confer site-dependent homing of circulating effector T cells to mucosal tissues. Specific homing molecules have been defined that can be measured in blood as surrogate markers of local immunity (e.g. α4β7 for gut. Here we analyzed the expression pattern of adhesion molecules by circulating effector T cells following mucosal infection of the female genital tract in mice and during a symptomatic episode of vaginosis in women. While CCR2, CCR5, CXCR6 and CD11c were preferentially expressed in a mouse model of Chlamydia infection, only CCR5 and CD11c were clearly expressed by effector T cells during bacterial vaginosis in women. Other homing molecules previously suggested as required for homing to the genital mucosa such as α4β1 and α4β7 were also differentially expressed in these patients. However, CD11c expression, an integrin chain rarely analyzed in the context of T cell immunity, was the most consistently elevated in all activated effector CD8+ T cell subsets analyzed. This molecule was also induced after systemic infection in mice, suggesting that CD11c is not exclusive of genital tract infection. Still, its increase in response to genital tract disorders may represent a novel surrogate marker of mucosal immunity in women, and warrants further exploration for diagnostic and therapeutic purposes.

  3. Interrelationships Within the Bacterial Flora of the Female Genital Tract

    Directory of Open Access Journals (Sweden)

    Henry J. Carson

    1997-01-01

    Full Text Available 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.

    The female genital tract includes several anatomical regions whose luminal fluids successively interact with gametes and embryos and are involved in the fertilisation and development processes. The luminal fluids from the inner cervix, the uterus and the oviduct were collected along the oestrous cycle at oestrus (Day 0 of the cycle) and during the luteal phase (Day 10) from adult cyclic ewes. The proteomes were assessed by GeLC-MS/MS and quantified by spectral counting. A set of 940 proteins were identified including 291 proteins differentially present along the cycle in one or several regions. The global analysis of the fluid proteomes revealed a general pattern of endocrine regulation of the tract, with the cervix and the oviduct showing an increased differential proteins abundance mainly at oestrus while the uterus showed an increased abundance mainly during the luteal phase. The proteins more abundant at oestrus included several families such as the heat shock proteins (HSP), the mucins, the complement cascade proteins and several redox enzymes. Other proteins known for their interaction with gametes such as oviductin (OVGP), osteopontin, HSPA8, and the spermadhesin AWN were also overexpressed at oestrus. The proteins more abundant during the luteal phase were associated with the immune system such as ceruloplasmin, lactoferrin, DMBT1, or PIGR, and also with tissue remodeling such as galectin 3 binding protein, alkaline phosphatase, CD9, or fibulin. Several proteins differentially abundant between estrus and the luteal phase, such as myosin 9 and fibronectin, were also validated by immunohistochemistry. The potential roles in sperm transit and uterine receptivity of the proteins differentially regulated along the cycle in the female genital tract are discussed. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.

  5. Female reproductive tract pain: targets, challenges, and outcomes

    2014-02-01

    Full Text Available Pain from the female reproductive tract (FRT is a significant clinical problem for which there are few effective therapies. The complex neuroantomy of pelvic organs not only makes diagnosis of pelvic pain disorders difficult but represents a challenge to development of targeted therapies. A number of potential therapeutic targets have been identified on sensory neurons supplying the FRT but our knowledge on the basic neurophysiology of these neurons is limited compared with other viscera. Until this is addressed we can only guess if the new experimental therapies proposed for somatic, gastrointestinal or bladder pain will translate to the FRT. Once suitable therapeutic targets become clear, the next challenge is drug delivery. The FRT represents a promising system for topical drug delivery that could be tailored to act locally or systemically depending on formulation. Development of these therapies and their delivery systems will need to be done in concert with more robust in vivo and in vitro models of FRT pain.

  6. Gene duplication and adaptive evolution of digestive proteases in Drosophila arizonae female reproductive tracts.

    Full Text Available It frequently has been postulated that intersexual coevolution between the male ejaculate and the female reproductive tract is a driving force in the rapid evolution of reproductive proteins. The dearth of research on female tracts, however, presents a major obstacle to empirical tests of this hypothesis. Here, we employ a comparative EST approach to identify 241 candidate female reproductive proteins in Drosophila arizonae, a repleta group species in which physiological ejaculate-female coevolution has been documented. Thirty-one of these proteins exhibit elevated amino acid substitution rates, making them candidates for molecular coevolution with the male ejaculate. Strikingly, we also discovered 12 unique digestive proteases whose expression is specific to the D. arizonae lower female reproductive tract. These enzymes belong to classes most commonly found in the gastrointestinal tracts of a diverse array of organisms. We show that these proteases are associated with recent, lineage-specific gene duplications in the Drosophila repleta species group, and exhibit strong signatures of positive selection. Observation of adaptive evolution in several female reproductive tract proteins indicates they are active players in the evolution of reproductive tract interactions. Additionally, pervasive gene duplication, adaptive evolution, and rapid acquisition of a novel digestive function by the female reproductive tract points to a novel coevolutionary mechanism of ejaculate-female interaction.

    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.

    Reports on bacteria detected in maternal fluids during pregnancy are typically associated with adverse consequences, and whether the female reproductive tract harbours distinct microbial communities beyond the vagina has been a matter of debate. Here we systematically sample the microbiota within the female reproductive tract in 110 women of reproductive age, and examine the nature of colonisation by 16S rRNA gene amplicon sequencing and cultivation. We find distinct microbial communities in cervical canal, uterus, fallopian tubes and peritoneal fluid, differing from that of the vagina. The results reflect a microbiota continuum along the female reproductive tract, indicative of a non-sterile environment. We also identify microbial taxa and potential functions that correlate with the menstrual cycle or are over-represented in subjects with adenomyosis or infertility due to endometriosis. The study provides insight into the nature of the vagino-uterine microbiome, and suggests that surveying the vaginal or cervical microbiota might be useful for detection of common diseases in the upper reproductive tract.Whether the female reproductive tract harbours distinct microbiomes beyond the vagina has been a matter of debate. Here, the authors show a subject-specific continuity in microbial communities at six sites along the female reproductive tract, indicative of a non-sterile environment.

    Full Text Available Most cancer patients are treated with some combination of surgery, radiation, and chemotherapy. Despite recent advances in local therapy with curative intent, chemotherapeutic treatments for metastatic disease often remain unsatisfying due to severe side effects and incomplete long-term remission. Therefore, the evaluation of novel therapeutic options is of great interest. Conventional, along with newer treatment strategies target the immune system that suppresses genitourinary (GU malignancies. Metastatic renal cell carcinoma and non-muscle-invasive bladder caner represent the most immune-responsive types of all human cancer. This review examines the rationale and emerging evidence supporting the anticancer activity of immunotherapy, against GU malignancies.

    Deruaz, Maud; Luster, Andrew D

    2015-04-01

    The genital tract mucosa is the site where sexually transmitted infections gain entry to the host. The immune response at this site is thus critical to provide innate protection against pathogens that are seen for the very first time as well as provide long-term pathogen-specific immunity, which would be required for an effective vaccine against sexually transmitted infection. A finely regulated immune response is therefore required to provide an effective barrier against pathogens without compromising the capacity of the genital tract to allow for successful conception and fetal development. We review recent developments in our understanding of the immune response in the female genital tract to infectious pathogens, using herpes simplex virus-2, human immunodeficiency virus-1 and Chlamydia trachomatis as examples, with a particular focus on the role of chemokines in orchestrating immune cell migration necessary to achieve effective innate and adaptive immune responses in the female genital tract.

    An issue that is currently undergoing extensive study is the influence of human vaginal microbiota (VMB) on the health status of women and their neonates. Healthy women are mainly colonised with lactobacilli such as Lactobacillus crispatus, Lactobacillus jensenii, and Lactobacillus iners; however, other bacteria may be elements of the VMB, particularly in women with bacterial vaginosis. The implementation of culture-independent molecular methods in VMB characterisation, especially next-generation sequencing, have provided new information regarding bacterial diversity in the vagina, revealing a large number of novel, fastidious, and/or uncultivated bacterial species. These molecular studies have contributed new insights regarding the role of bacterial community composition. In this study, we discuss recent findings regarding the reproductive tract microbiome. Not only bacteria but also viruses and fungi constitute important components of the reproductive tract microbiome. We focus on aspects related to the impact of the maternal microbiome on foetal development, as well as the establishment of the neonatal microbiomes, including the placenta microbiome, and the haematogenous source of intrauterine infection. We also discuss whether the role of the vaginal microbiome is currently understood and appreciated.

    Staphylococcus saprophyticus is a rarely reported agent of urinary tract infection (UTI) in the pediatric population. In our retrospective 3-year study, S. saprophyticus comprised 24.5% of 106 isolates of UTIs in female adolescents 12-15 years of age who attended an emergency department. Clinicians should be aware of the high prevalence of this etiology when empirically treating UTIs in female adolescents.

    Full Text Available Abstract Treatment of cancer patients involves a multidisciplinary approach including surgery, radiotherapy, and chemotherapy. Traditionally, patients with metastatic disease are treated with combination chemotherapies or targeted agents. These cytotoxic agents have good response rates and achieve palliation; however, complete responses are rarely seen. The field of cancer immunology has made rapid advances in the past 20 years. Recently, a number of agents and vaccines, which modulate the immune system to allow it to detect and target cancer cells, are being developed. The benefit of these agents is twofold, it enhances the ability the body’s own immune system to fight cancer, thus has a lower incidence of side effects compared to conventional cytotoxic chemotherapy. Secondly, a small but substantial number of patients with metastatic disease are cured by immunotherapy or achieve durable responses lasting for a number of years. In this article, we review the FDA-approved immunotherapy agents in the field of genitourinary malignancies. We also summarize new immunotherapy agents being evaluated in clinical studies either as single agents or as a combination.

    The aim of the study was to investigate the clinical manifestations, diagnosis, treatment, and prognosis of primitive neuroectodermal tumors (PNETs) in the female genital tract. From April 2001 to May 2013, the clinicopathologic characteristics, treatments, outcomes, and prognosis of 11 patients with PNET in the female genital tract were analyzed retrospectively at our hospital. The location of PNET in the 11 patients presented here included vulva (2 patients), cervix (2 patients), uterus and its ligament (5 patients), and the ovaries (2 patients). Ages ranged from 18 to 59 years (median, 31 years).The main clinical manifestations of PNET in the female genital tract are irregular vaginal bleeding (6 patients), pelvic mass, uterine enlargement, and rapidly increasing vulvar mass (8 patients), and vulvar pain and lower abdominal pain (5 patients). The CA125 levels of 8 patients were elevated before the operations and reduced to normal when the diseases were controlled, while the levels increased as the tumor was progressive. Results for the most commonly used immunohistochemistry studies revealed CD99 in 11 of the 11 tumors, synaptophysin in 6 of the 7 positive tumors, and neuron-specific enolase in 6 of the 6 tumors. Ten patients underwent surgical resection. Nine of them underwent preoperative or/and postoperative combination chemotherapy. The follow-up of 10 patients were available and ranged from 1 to 145 months (median, 30.5 months), 3 of whom experiencing recurrence. Primitive neuroectodermal tumor is very rare and can originate from any part of the female genital tract. The tumors had different manifestations but the same pathologic features. CA125 may be an important marker for prognosis and follow-up of PNET of the female internal genital tract.

    Chlamydia trachomatis is a Gram-negative obligate intracellular bacterial pathogen. It is the leading cause of bacterial sexually transmitted disease in the world, with more than 100 million new cases of genital tract infections with C. trachomatis occurring each year. Animal models are indispensable for the study of C. trachomatis infections and the development and evaluation of candidate vaccines. In this paper, the most commonly used animal models to study female genital tract infections with C. trachomatis will be reviewed, namely, the mouse, guinea pig, and nonhuman primate models. Additionally, we will focus on the more recently developed pig model.

    Full Text Available Neuromodulation is becoming part of clinical armamentarium for treatment of a variety of lower urinary tract conditions in female urology. Its increased usage stems from need of patients who have exhausted all other therapeutic options for their complex and poorly understood lower urinary tract disorders. Currently neuromodulation may consist of the use of sacral nerve stimulation (SNS and injectable therapies. Herein, we will discuss the background and development of SNS, its current indications, methods of patient selection and will review the results of the recent published literature on SNS. In addition, we will discuss some of the newer developments in SNS such as Bion device and the future direction in integration of SNS in female urology.

    Full Text Available Lower urinary tract symptoms (LUTS are a common health problem causing considerable inconvenience to many women. Moreover, they are non-specific and can be caused by a large number of disorders. A thorough evaluation, including physical examination, imaging studies, and urodynamic investigation of the lower urinary tract, is crucial for appropriate management of bothersome symptoms. Ultrasonography has the advantages of non-invasiveness, reproducibility, no radiation exposure, and low cost. With the use of a high-resolution transducer, pelvic organs can be demonstrated clearly on ultrasonography. In addition, three-dimensional sonography provides a clear demonstration of the spatial orientation of the female lower urinary tract. Both color and power Doppler scanning can not only reveal the vascular flow in pelvic organs, but also demonstrate urinary flow. Ultrasonography has dual functions in the management of female LUTS: diagnosis and intervention. It may help physicians to recognize the anatomic characteristics of specific pelvic floor disorders, to explore the pathophysiologic mechanism responsible for pelvic floor dysfunction, and to assist in the surgical management of LUTS with minimal invasion. Since female LUTS may originate from gynecologic or nongynecologic conditions, it is more convenient and helpful to obtain transvaginal and introital sonograms at the same time by using an endovaginal probe.

  10. Pattern Recognition via the Toll-Like Receptor System in the Human Female Genital Tract

    2010-01-01

    Full Text Available The mucosal surface of the female genital tract is a complex biosystem, which provides a barrier against the outside world and participates in both innate and acquired immune defense systems. This mucosal compartment has adapted to a dynamic, non-sterile environment challenged by a variety of antigenic/inflammatory stimuli associated with sexual intercourse and endogenous vaginal microbiota. Rapid innate immune defenses against microbial infection usually involve the recognition of invading pathogens by specific pattern-recognition receptors recently attributed to the family of Toll-like receptors (TLRs. TLRs recognize conserved pathogen-associated molecular patterns (PAMPs synthesized by microorganisms including bacteria, fungi, parasites, and viruses as well as endogenous ligands associated with cell damage. Members of the TLR family, which includes 10 human TLRs identified to date, recognize distinct PAMPs produced by various bacterial, fungal, and viral pathogens. The available literature regarding the innate immune system of the female genital tract during human reproductive processes was reviewed in order to identify studies specifically related to the expression and function of TLRs under normal as well as pathological conditions. Increased understanding of these molecules may provide insight into site-specific immunoregulatory mechanisms in the female reproductive tract.

    Female genital tract graft-versus-host disease (GVHD) is an under-recognized complication of allogeneic stem cell transplantation impacting on quality of life. We describe a prospective surveillance programme for female genital GVHD to better characterize incidence, risk factors and clinical features and the impact of a structured intervention policy. A retrospective audit was conducted on the medical records of all female transplant recipients surviving at least 6 months at a single centre over a 5-year period. Patients commenced topical vaginal oestrogen early post transplant with hormone replacement as appropriate for age, prior menopausal status and co-morbidities. A genital tract management programme included regular gynaecological review and self-maintenance of vaginal capacity by dilator or intercourse. The incidence of genital GVHD was 35% (95% confidence interval (CI) (25, 50%)) at 1 year and 49% (95% CI (36, 63%)) at 2 years. Topical therapy was effective in most cases; no patient required surgical intervention to divide vaginal adhesions. The main risk factor was stem cell source with peripheral blood progenitor cells posing a higher risk than marrow (hazard ratio=3.07 (1.22, 7.73), P=0.017). Extensive GVHD in other organs was a common association. We conclude that female genital GVHD is common, and early detection and commencement of topical immunosuppression with dilator use appears to be highly effective at preventing progression.

    Women constitute almost half of HIV-infected population globally, and the female genital tract (FGT) accounts for approximately 40% of all new HIV infections worldwide. The FGT is composed of upper and lower parts, distinct in their morphological and functional characteristics. Co-factors in the genital microenvironment, such as presence of hormones, semen, and other sexually transmitted infections, can facilitate or deter HIV infection and play a critical role in determining susceptibility to HIV. In this review, we examine some of these co-factors and their potential influence. Presence of physical and chemical barriers such as epithelial tight junctions, mucus, and anti-microbial peptides can actively block and inhibit viral replication, presenting a significant deterrent to HIV. Upon exposure, HIV and other pathogens first encounter the genital epithelium: cells that express a wide repertoire of pattern recognition receptors that can recognize and directly initiate innate immune responses. These and other interactions in the genital tract can lead to direct and indirect inflammation and enhance the number of local target cells, immune activation, and microbial translocation, all of which promote HIV infection and replication. Better understanding of the dynamics of HIV transmission in the female genital tract would be invaluable for improving the design of prophylactic strategies against HIV. © 2014 John Wiley & Sons A/S.

    Urinary tract infections (UTIs) are the most common bacterial infections seen in the community, especially amongst females. The widespread use of antibiotics has led to the increased occurrence of E. coli resistant isolates worldwide. A promising non-antibiotic approach is the use of probiotic lactobacilli strains. This paper hypothesizes that Lactobacillus spp. containing products are able to prevent recurrent urinary tract infections in females. Using the keywords [lactobacillus OR lactobacilli OR probiotic] and [urinary tract infection OR UTI OR cystitis], a preliminary search on the PubMed, Ovid, Google Scholar and ClinicalTrials.gov database yielded 1,647 papers published in English between 1-Jan-1960 and 1-May-2017. 9 clinical trials with a total of 726 patients were reviewed. Different lactobacilli strains (in either oral or suppository formulation) were utilized and they demonstrated varying efficacy in the prevention of recurrent UTIs. Using a random-effects model, pooled risk ratio of at least one recurrent UTI episode during the entire study duration was 0.684 (95% CI 0.438 to 0.929, p probiotics for UTIs is plausible and supported by current data. Lactobacillus rhamnosus GR1 and Lactobacillus reuteri RC14 were the most commonly studied lactobacilli strains. Further and more robust randomized controlled trials with standardized lactobacilli strains and formulation are required for confirmation of effects. Copyright © 2018 Elsevier Ltd.

    The morphological and histological features of the unusual reproductive tract of the female lesser anteater, Tamandua tetradactyla (Myrmecophagidae, Xenarthra), are described for the first time. The present study aimed to establish the main similarities and differences between this species and other xenarthrans. The populations of this species are declining rapidly for a number of reasons and our study is relevant to diverse programs related to its conservation. Studies were carried out on five female genital tracts of adult specimens. Ovaries were ovoid, presenting a medulla completely surrounded by the cortex, differently from that described in other xenarthans. Like in Dasypus but different from all other armadillos studied, single oocyte follicles were observed and a simple the uterus. The uterovaginal canal connects the uterus with the urogenital sinus. The simple columnar epithelium of the uterovaginal canal ends abruptly at a septum which resembles a hymen, where the transitional epithelium of the urogenital sinus appears. This ancestral feature is shared with that of other armadillos, except Tolypeutes matacus, which has a true vagina. Characteristics of the reproductive tract and sperm morphology of other Xenarthra are comparatively discussed. These observations suggest that important reproductive features are shared between the family Myrmecophagidae and the genus Dasypus, a basal group in the phylogeny of Xenarthra.

    Three reproductively quiescent female emus (Dromaius novaehollandiae) were embalmed with 10% formalin solution. The reproductive tract was dissected and described. The reproductive tract consists of an ovary and oviduct situated on the left side of the abdominal cavity. The left ovary is dark brown to black in colour with follicles covering the ventral surface. The ovary is located medial to the spleen and closely associated with the ventral surface of the cranial and middle lobes of the left kidney. The oviduct is a relatively straight tube that extends from the level of the cranial extent of the left ilium to the caudal border of the left pubic bone. The oviduct is grossly divided into the infundibulum, magnum, isthmus, uterus and vagina using variations in the mucosal fold pattern. © 2010 Blackwell Verlag GmbH.

  17. Lactic acid alleviates stress: good for female genital tract homeostasis, bad for protection against malignancy.

    Science.gov (United States)

    Witkin, Steven S

    2018-05-01

    Women are unique from all other mammals in that lactic acid is present at high levels in the vagina during their reproductive years. This dominance may have evolved in response to the unique human lifestyle and a need to optimally protect pregnant women and their fetuses from endogenous and exogenous insults. Lactic acid in the female genital tract inactivates potentially pathogenic bacteria and viruses, maximizes survival of vaginal epithelial cells, and inhibits inflammation that may be damaging to the developing fetus and maintenance of the pregnancy. In an analogous manner, lactic acid production facilitates survival of malignantly transformed cells, inhibits activation of immune cells, and prevents the release of pro-inflammatory mediators in response to tumor-specific antigens. Thus, the same stress-reducing properties of lactic acid that promote lower genital tract health facilitate malignant transformation and progression.

    Full Text Available Purpose and Methods: This is a series of three cases diagnosed with xanthogranulomatous inflammation of the female genital with emphasis on the etiology, clinical-pathologic features and biological behavior. Clinical, pathologic, radiologic and follow up data are reported.Results: The three cases of Xanthogranulomatous inflammation of the female genital tract are the followings: 1 one case affecting the endometrium, 2 one case affecting the fallopian tube, and 3 one case confined to the ovary. The patient's age was 37, 22 and 62 year-old, respectively. Histologic examination revealed extensive infiltration of foamy histiocytes admixed with variable amount of inflammatory cells. The later include plasma cells, lymphocytes, and occasional multinucleated giant cells. Immunohistochemistry showed positive staining for CD68, a histiocytic marker, in foamy histiocytes, CD3, a T cell marker, and CD20, a B cell marker, in the background lymphocytes. The plasma cells were polyclonal with expression of both κ and λ light chains.Conclusion: Xanthogranulomatous inflammation of the female genital tract is an unusual lesion, and clinically forms mass- like lesion in the pelvic cavity that invades the surrounding tissues, which may mimic the tumor clinically and by imaging.

    Yeasts are commensal organisms found in the reproductive and gastrointestinal tracts, and on the skin and other mucosa in mammals. The purpose of this study was to isolate and identify yeast flora in the caudal reproductive tract in healthy female horses. Longitudinal study. A total of 453 samples were collected using double-guarded swabs from the vestibule, clitoral fossa and vagina in 151 horses. All samples were cultured on Sabouraud 4% dextrose agar and incubated at 35°C for 7-10 days. Isolates were identified according to their morphological characteristics and biochemical profiles. Yeast colonies were isolated from 60 (39.7%) of the 151 horses. The isolated yeasts belonged to nine genera, and included Candida spp. (53.2%), Cryptococcus spp. (12.2%), Saccharomyces spp. (10.5%), Geotrichum spp. (8.0%), Rhodotorula spp. (7.1%), Malassezia spp. (3.7%), Trichosporon spp. (2.6%), Kluyveromyces spp. (2.6%) and Sporothrix spp. (0.2%). Candida krusei (43.1%) was the most frequent Candida species isolated. There was a significant difference in prevalence between C. krusei and other Candida species (Pyeast isolates (48.0%) than the vagina (18.3%). The isolation of yeast colonies from multiparous females (76.8%) was significantly higher than from maiden mares (P<0.05). The study was limited by the difficulty of distinguishing between normal flora and potential pathogens. Candida spp., in particular C. krusei, represent important flora resident in the caudal reproductive tract in healthy female horses. This is particularly important in contexts that require the initiation of empirical treatment prior to the completion of culture results. © 2016 EVJ Ltd.

    In order to improve the diagnostic accuracy of malignant tumors with laser fluorescence, in 1996, our group successfully created the computerized laser fluorescence spectrograph type II with more reliable images shown overshadowing the naked eye method before 74 cases of female genital tract diseases had been examined by the LFS II resulting in 10 positive cases which were also proven pathologically as malignant tumors, without nay false negative, 3 cases presented suspicious positive but all were proven pathologically as non-tumors lesions, the false positive rate was 4 percent. Our work showed that the method of LFS II can provide a more rapid and accurate diagnosis for the clinical malignant tumors.

  1. Pharmacokinetics of antiretroviral drugs in anatomical sanctuary sites: the male and female genital tract.

    2011-01-01

    HIV resides within anatomical 'sanctuary sites', where local drug exposure and viral dynamics may differ significantly from the systemic compartment. Suboptimal antiretroviral concentrations in the genital tract may result in compartmentalized viral replication, selection of resistant mutations and possible re-entry of wild-type/resistant virus into the systemic circulation. Therefore, achieving adequate antiretroviral exposure in the genital tract has implications for the prevention of sexual and vertical transmission of HIV. Penetration of antiretrovirals in the genital tract is expressed by accumulation ratios derived from the measurement of drug concentrations in time-matched seminal plasma/cervicovaginal fluid and plasma samples. Penetration varies by gender and may be drug (as opposed to class) specific with high interindividual variability. Concentrations in seminal plasma are highest for nucleoside analogues and lowest for protease inhibitors and efavirenz. Seminal accumulation of newer agents, raltegravir and maraviroc, is moderate (rank order of accumulation is nucleoside/nucleotide reverse transcriptase inhibitors [lamivudine/zidovudine/tenofovir/didanosine > stavudine/abacavir] > raltegravir > indinavir/maraviroc/nevirapine > efavirenz/protease inhibitors [amprenavir/atazanavir/darunavir > lopinavir/ritonavir > saquinavir] > enfuvirtide). In the female genital tract, the nucleoside analogues exhibit high accumulation ratios, whereas protease inhibitors have limited penetration; however, substantial variability exists between individuals and study centres. Second generation non-nucleoside reverse transcriptase inhibitor etravirine, and maraviroc and raltegravir, demonstrate effective accumulation in cervicovaginal secretions (rank order of accumulation is nucleoside/nucleotide reverse transcriptase inhibitor [zidovudine/lamivudine/didanosine > emtricitabine/tenofovir] > indinavir > maraviroc/raltegravir/darunavir/etravirine > nevirapine

    Female genital tract malignancy is common in our low resource setting. Options now exist for prevention, detection, treatment, and palliative care for the wide spectrum of female genital tract malignancies. Women will continue to die from these cancers unless health professionals and civil society adopt means to control female genital tract cancers in our low resource setting. The objective was to determine the frequency and patterns of female genital tract malignancy at the University of Nigeria Teaching Hospital (UNTH), Enugu, Nigeria. A 6-year retrospective study of female genital tract malignancies was conducted at the UNTH, Enugu. The case notes of patients admitted for female genital tract malignancy between January 1, 2003 and December 31, 2008 were retrieved from the medical records and cancer registry of the University of Nigeria Teaching Hospital, Enugu and relevant data were extracted. The data were analyzed using SPSS version 12 (SPSS Inc., Chicago, IL, USA) and the results expressed in descriptive statistics by simple percentages. One hundred and sixty six (166) cases of genital malignancies were recorded during the 6-year review. Majority of the patients were in the fifth and sixth decades of life. Cancer of the cervix accounted for 66.3% (110/166) followed by ovarian cancer 21.1% (35/166). The other tumors seen during the period were tumors involving corpus uteri 9% (15/166) and vulva 3.6% (6/166). Tumors of fallopian tube and vagina were not seen during the study period. Despite the preventable nature of cancer of cervix, it remained the most common female genital tract malignancy in Enugu, South-East Nigeria. In our low resource setting in the developing countries, education and public enlightenment on the importance of routine screening and treatment of premalignant lesions of the cervix are necessary tools to reduce the incidence and mortality of cervical cancer.

  3. Innate immunity and the sensing of infection, damage and danger in the female genital tract.

    2017-02-01

    Tissue homeostasis in the female genital tract is challenged by infection, damage, and even physiological events during reproductive cycles. We propose that the evolutionarily ancient system of innate immunity is sufficient to sense and respond to danger in the non-pregnant female genital tract. Innate immunity produces a rapidly inducible, non-specific response when cells sense danger. Here we provide a primer on innate immunity and discuss what is known about how danger signals are sensed in the endometrium and ovary, the impact of inflammatory responses on reproduction, and how endocrinology and innate immunity are integrated. Endometrial epithelial and stromal cells, and ovarian granulosa cells express pattern recognition receptors, similar to cells of the innate immune system. These pattern recognition receptors, such as the Toll-like receptors, bind pathogen-associated or damage-associated molecular patterns. Activation of pattern recognition receptors leads to inflammation, recruitment of immune cells from the peripheral circulation, and phagocytosis. Although the inflammatory response helps maintain or restore endometrial health, there may also be negative consequences for fertility, including perturbation of oocyte competence. The intensity of the inflammatory response reflects the balance between the level of danger and the systems that regulate innate immunity, including the endocrine environment. Understanding innate immunity is important because disease and inappropriate inflammatory responses in the endometrium or ovary cause infertility. Copyright © 2016 Elsevier Ireland Ltd.

    The aim of the present study was to elucidate the clinico-pathological characteristics of female patients with lower genital tract rhabdomyosarcoma (RMS) stratified by age group and investigate their prognosis, using a multi-institutional database. The National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) database was accessed (1973-2013) and a cohort of females diagnosed with RMS of the lower genital tract (vulva, vagina, cervix) was drawn. Five-year overall survival (OS) rate was estimated following generation of Kaplan-Meier curves and compared with the log-rank test. A total of 144 eligible cases were identified; 51.4 and 48.6% originated from the vagina/vulva and the cervix, respectively. Median patient age was 16 years and distant metastases were rare (ten cases). The majority of tumors were of embryonal histology (75.7%). Non-embryonal RMS was more prevalent in the older patient groups. Tumors originating from the cervix were more common among adolescents and premenopausal women. Rate of LN involvement was 52.9 and 20% for vulvovaginal and cervical tumors (p = 0.02). Five-year OS rate was 68.4%; factors associated with better OS were younger age, absence of distant metastasis, embryonal histology, negative LNs, and performance of surgery. For prepubertal girls and adolescents, radical surgery did not confer a survival benefit compared to local tumor excision. RMS of the lower genital tract primarily affects prepubertal girls and adolescents, who have excellent survival rates; however, outcomes for adults remain poor.

    We have used the monoclonal estrogen receptor (ER) antibody H222Sp gamma to localize ER by immunocytochemistry in frozen sections of the normal canine urinary tract of both sexes and of the normal prostate of the male. Striking regional heterogeneity of ER location was observed. In the urinary tract, specific ER staining was confined to nuclei of the transitional epithelium (mucosa) and subjacent stroma (submucosa) of the prostatic urethra in the male dog and of the proximal urethra in the female dog. In both sexes there was a gradient of ER staining intensity along these urethral segments. In the male, ER staining intensity was highest in the region of the verumontanum. The pattern and intensity of staining were similar in the male prostatic urethra and female proximal urethra, indicating a similar concentration of ER in these tissues, which have the same embryological origin. No specific staining was found in the kidney, ureter, bladder, or distal urethra of either sex. In the normal prostate, specific immunocytochemical ER staining was confined to nuclei of the prostatic stroma and prostatic ductal epithelium. Specific staining intensity appeared to be higher in the periurethral region of the prostate than in the periphery. No specific staining was found in the acinar epithelium of the prostate. Based on overall staining intensity there appeared to be a higher concentration of ER in the urethra than in the prostate. Scatchard analysis of [ 3 H]estradiol binding confirmed a similar ER content in the urethra of male and female dogs and a higher ER content in the prostatic urethra than in the prostate itself (P less than 0.001)

    It has been shown that herbs that contain aristolochic acid induce urological cancer. Chinese herbalists have easy access to such herbs. Our previous mortality study has shown a significantly increased risk of urological cancer in female but not male herbalists. To re-examine this risk in male herbalists, the incidence of urological cancer was analyzed. We enrolled all 6550 Chinese herbalists in Taiwan registered during 1985-2000, and we retrospectively followed the development of cancer until 2001 by analysis of data collected from the Taiwan Cancer Registry. Standardized incidence ratios (SIRs) were calculated for urological cancers in herbalists and compared with those for the general population in Taiwan. There were 30 newly diagnosed cases of urological cancer and most of them were transitional cell carcinoma (93.1%). The mean age at diagnosis for urothelial carcinoma was 51.6 years, and 51.9% were in the upper urinary tract. After adjustment for age and sex, the SIR for all urological cancers was 3.51 [(95% confidence interval (CI): 2.37-5.01]. When stratified by location, the SIRs for kidney and upper urinary tract cancers and bladder cancer were 4.24 (95% CI: 2.47-6.80) and 2.86 (95% CI: 1.52-4.89), respectively. When analyzed by sex, the SIRs for all urological cancers, kidney and upper urinary tract cancers, and bladder cancer were also significantly increased in male herbalists. The significant risk of urothelial carcinoma noted in male herbalists increases our suspicion that this is an occupational disease that renders regular health assessment of herbalists an urgent necessity.

    Full Text Available Female genital tract secretions are bactericidal for Escherichia (E. coli ex vivo. However, the intersubject variability and molecules that contribute to this activity have not been defined.The bactericidal activity and concentration of immune mediators in cervicovaginal lavage (CVL collected from 99 healthy women were determined.CVL reduced the number of E. coli colonies by 68% [-26, 100] (median [range]. CVL were active against laboratory and clinical isolates of E. coli, but were inactive against Lactobacillus species. Bactericidal activity correlated with the concentration of protein recovered (p90% inhibitory activity (active and two with<30% activity were subjected to MS/MS proteomic analysis. 215 proteins were identified and six were found exclusively in active samples. Four of these corresponded to Lactobacillus crispatus or jensenii proteins. Moreover, culture supernatants from Lactobacillus jensenii were bactericidal for E. coli.Both host and commensal microbiota proteins contribute to mucosal defense. Identification of these proteins will facilitate the development of strategies to maintain a healthy vaginal microbiome and prevent colonization with pathogenic bacteria such as E. coli that increase the risk for urinary tract infections, preterm labor and perinatal infection.

    The exposure of oral antiretroviral (ARV) drugs in the female genital tract (FGT) is variable and almost unpredictable. Identifying an efficient method to find compounds with high tissue penetration would streamline the development of regimens for both HIV preexposure prophylaxis and viral reservoir targeting. Here we describe the cheminformatics investigation of diverse drugs with known FGT penetration using cluster analysis and quantitative structure-activity relationships (QSAR) modeling. A literature search over the 1950-2012 period identified 58 compounds (including 21 ARVs and representing 13 drug classes) associated with their actual concentration data for cervical or vaginal tissue, or cervicovaginal fluid. Cluster analysis revealed significant trends in the penetrative ability for certain chemotypes. QSAR models to predict genital tract concentrations normalized to blood plasma concentrations were developed with two machine learning techniques utilizing drugs' molecular descriptors and pharmacokinetic parameters as inputs. The QSAR model with the highest predictive accuracy had R(2)test=0.47. High volume of distribution, high MRP1 substrate probability, and low MRP4 substrate probability were associated with FGT concentrations ≥1.5-fold plasma concentrations. However, due to the limited FGT data available, prediction performances of all models were low. Despite this limitation, we were able to support our findings by correctly predicting the penetration class of rilpivirine and dolutegravir. With more data to enrich the models, we believe these methods could potentially enhance the current approach of clinical testing.

    Stress urinary incontinence (SUI), the most common type of urinary incontinence (UI), is usually defined as leakage of urine during movement or activity which puts pressure on the bladder, such as coughing, sneezing, running or heavy lifting. It is reported in most countries that 15% to 40% of women struggle with SUI and its severe implications for daily life, including social interactions, sexuality, and psychological wellbeing. The aim of our study was to assess the relationship between urinary tract infection and the severity of stress urinary incontinence (SUI). This research was a cross-sectional study conducted in a public urology clinic in Tehran. The study population was all females with complaints of SUI who visited the clinic during 2014. We compared Valsalva leak point pressure (VLPP) in two groups of patients, with and without history of urinary tract infection (UTI). According to the findings of our study, the mean VLPP was 83.10 cm H2O in the group with UTI history, and 81.29 cm H2O in those without history of UTI. The difference in VLPP between the two groups was not significant (P < 0.05), even after controlling for confounding variables including age, body mass index, history of hysterectomy and number of deliveries. Our study did not confirm a significant relationship between UTI and severity of SUI as measured by VLPP. A decisive opinion would require extensive future studies by prospective methods.

    The anatomy and histology of the female reproductive tract of the Indonesian wild pig Babyrousa celebensis was studied by means of reproductive tracts obtained from seven animals aged between two and 22 years of age. The ovary appeared to have the ability to ovulate up to four ova at one time. However, the combined ovarian output seemed to average 1.86 ova. Ovulation can take place at any time from puberty to old age (22 years). The opening to the uterine tube was indicated by a 'flower-like' array of tall, broad epithelial 'petals' arising from the luminal surface of the funnel. The mucosal surfaces of these structures were covered in a mixture of prominent ciliated cells and bulbous secretory cells. The uterine tube followed a tightly convoluted path to the tip of the uterine horn. The uterus was proportionately short. The anatomical construction of the uterus was similar to those of other suids in that the columnar endometrium was heavily folded, there was a rich supply of uterine glands in the lamina propria, and the uterus was provided with a good blood supply. The cervix was thick walled and had a spiral lumen. Copyright 2010 Elsevier Inc. All rights reserved.

    A 20-year-old woman and 3 girls were referred to our urodynamic unit because of refractory bed wetting, recurrent urinary tract infection, and/or weak stream. All patients required extremely high detrusor pressure to evacuate urine, a mean of 116 cm of water. Urethral configuration was either a ballooning or a spinning-top shape. Organic stenosis of the urethra was not detected by bougie à boule. Urodynamically, functional obstruction at the distal urethra was found to be an etiology of these symptoms. When the urethra was dilated with the Otis urethrotome, all patients were greatly benefitted both symptomatically and urodynamically without an adverse effect of urinary incontinence. We stress clinical importance of pressure flow study and fluoroscopic monitoring of the bladder and urethra when one encounters female patients with long histories of above symptoms.

    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

    Colonization by Lactobacillus in the female genital tract is thought to be critical for maintaining genital health. However, little is known about how genital microbiota influence host immune function and modulate disease susceptibility. We studied a cohort of asymptomatic young South African women and found that the majority of participants had genital communities with low Lactobacillus abundance and high ecological diversity. High-diversity communities strongly correlated with genital pro-inflammatory cytokine concentrations in both cross-sectional and longitudinal analyses. Transcriptional profiling suggested that genital antigen-presenting cells sense gram-negative bacterial products in situ via Toll-like receptor 4 signaling, contributing to genital inflammation through activation of the NF-κB signaling pathway and recruitment of lymphocytes by chemokine production. Our study proposes a mechanism by which cervicovaginal microbiota impact genital inflammation and thereby might affect a woman's reproductive health, including her risk of acquiring HIV.

    Full Text Available Various studies have shown Staphylococcus aureus to be one of the most prevalent organism in male and female genital tract but most practitioners dismiss it as mere contamination which is assumed to be of no significance. However, it is now suggested that the presence of this organism should not be ignored, as incubation of spermatozoa with S. aureus results in reduced sperm motility. Although S. aureus has been reported to cause immobilization of spermatozoa, however, its role in infertility has yet to be elucidated. The present study was designed to establish a spermagglutinating strain of S. aureus isolated from the cervix of a woman with unexplained infertility, in mouse and evaluate its effect on fertility outcome. Female Balb/c mice were inoculated intravaginally with different doses of S. aureus (10(4, 10(6 or 10(8cfu/20 µl for 10 consecutive days. Microbial colonization monitored every 3(rd day by vaginal cultures, revealed that strain could efficiently colonize mouse vagina. Mating on day 12, with proven breeder males led to 100% decrease in fertility as compared to control. Even a single dose of 10(6 or 10(8cfu could lead to vaginal colonization which persisted for 10 days followed by gradual clearing till 21 days, vaginal cultures were negative thereafter. Female mice mated on day 7 (culture positive, were rendered infertile, however, the mice mated on day 22 (culture negative, retained fertility and delivered pups indicating its role in provoking infertility. Further, except infertility, no other clinical manifestation could be seen apparently or histologically. However, when a non-spermagglutinating/immobilizing standard strain of S. aureus MTCC6625 was inoculated intravaginally at 10(8cfu for 10 days followed by mating on day 12, fertility was observed in all the female mice. This supports the hypothesis that infertility observed in the former groups was as a result of colonization with spermagglutinating strain of S. aureus.

    Full Text Available Inflammation is a multifaceted process involving a host of resident and recruited immune cells that eliminate the insult or injury and initiate tissue repair. In the female reproductive tract (FMRT, inflammation-mediated alterations in epithelial, vascular, and immune functions are important components of complex physiological processes and many local and systemic pathologies. It is well established that intracoital and postcoital function of seminal fluid (SF goes beyond nutritive support for the spermatozoa cells. SF, in particular, the inflammatory bioactive lipids, and prostaglandins present in vast quantities in SF, have a role in localized immune modulation and regulation of pathways that can exacerbate inflammation in the FMRT. In sexually active women SF-mediated inflammation has been implicated in physiologic processes such as ovulation, implantation, and parturition while also enhancing tumorigenesis and susceptibility to infection. This review highlights the molecular mechanism by which SF regulates inflammatory pathways in the FMRT and how alterations in these pathways contribute to physiology and pathology of the female reproductive function. In addition, based on findings from TaqMan® 96-Well Plate Arrays, on neoplastic cervical cells treated with SF, we discuss new findings on the role of SF as a potent driver of inflammatory and tumorigenic pathways in the cervix.

    Full Text Available Objectives: 1 To study the risk factor profiles of lower urinary tract symptoms (LUTS among adolescent girls, housewives and working women and its socioeconomic and quality of life losses. 2 To undertake risk factor modifications using the adolescent girls. Design and Setting: Cross-sectional descriptive study followed by educational intervention. Statistical Methods: Cluster sampling, Proportions, confidence intervals, Chi square and t-Tests and Logistic regression. Materials and Methods: House to house survey was done in two villages and one urban ward. Seventy-five housewives, 75 working women and 180 adolescent girls were asked about the risk factors and losses due to LUTS. Three teams of adolescent girls were utilized to bring about behavioral modifications. Impact was measured through user perspectives obtained from the participants. Results: Risk factors, social, economic and quality of life losses were different among the three female populations. Overall prevalence of LUTS among the three groups is 61(18.5%. Improper anal washing technique, malnutrition, presence of vaginal discharge, use of unsanitary menstrual pads, pinworm infestation and use of bad toilets were the significant causes among girls. Presence of sexually transmitted diseases was a contributing factor among housewives and working women. Prolonged sitting the posture was also contributing to LUTS among working women. Seventy-four per cent of beneficiaries expressed that intervention is useful. Conclusions: The causes for LUTS and their consequences were differing among the three female subpopulations. Specific group level interventions using trained girls were successful.

  17. Innate immunity is sufficient for the clearance of Chlamydia trachomatis from the female mouse genital tract.

    2014-10-01

    Chlamydia muridarum and Chlamydia trachomatis, mouse and human strains, respectively, have been used to study immunity in a murine model of female genital tract infection. Despite evidence that unique genes of these otherwise genomically similar strains could play a role in innate immune evasion in their respective mouse and human hosts, there have been no animal model findings to directly support this conclusion. Here, we infected C57BL/6 and adaptive immune-deficient Rag1(-/-) female mice with these strains and evaluated their ability to spontaneously resolve genital infection. Predictably, C57BL/6 mice spontaneously cleared infection caused by both chlamydial strains. In contrast, Rag1(-/-) mice which lack mature T and B cell immunity but maintain functional innate immune effectors were incapable of resolving C. muridarum infection but spontaneously cleared C. trachomatis infection. This distinct dichotomy in adaptive and innate immune-mediated clearance between mouse and human strains has important cautionary implications for the study of natural immunity and vaccine development in the mouse model. © 2014 Federation of European Microbiological Societies.

    To assess the prevalence of lower urinary tract symptoms (LUTS) and incontinence in female athletes and to determine the etiological factors. An anonymous self-questionnaire was collected from 623 casual female athletes aged 18 to 56 years, who were involved in 12 different sports. The surveys were distributed by hand to the athletes, during their sports fitness tests, in a sports center. We investigated the relationship between urinary disorders and factors such as age, body mass index (BMI), parity, duration of physical exercise, and type of sport. The prevalence of LUTS was 54.7%, and 30% for urinary incontinence. Changes in urinary frequency were detected in 91 (14.6%) women. Prevalence of dysuria was 13.3%, urinary straining was present in 173 (27.8%) athletes, whereas urinary urgency had an estimated prevalence of 37.2% with 232 athletes suffering from this disorder. Urgency was very common in volleyball players, as was dysuria among hockey and basketball players, whereas straining mainly affected aerobic participants and cyclists. Long training hours and competitive practices were correlated with the onset of LUTS. High-impact sports were more frequently associated with incontinence, while low-impact sports with LUTS. The sport with the main number of incontinent people was football. Urge incontinence affected a lot of athletes, mainly cyclists and football players. Stress incontinence was more frequent in hockey and volleyball players. LUTS and incontinence are prevalent in female athletes. In many cases, the disorders were present only during sports activities. In this sample, the presence of urinary disorders did not seem to be a barrier during sports or exercise.

    To investigate lower urinary tract symptoms (LUTS) and voiding function in a cohort of hyperthyroid women. The autonomic nervous system (ANS) imbalance has been thought to cause LUTS in hyperthyroidism. Between January 2008 and December 2008, 65 newly diagnosed, untreated female hyperthyroid patients were enrolled in this study. Another 62 age-matched healthy women were enrolled as a control group. Demographics, LUTS, urinary flow rates, hyperthyroid symptoms, and serum levels of thyroid hormones were recorded before and after the medical treatment for hyperthyroidism. Compared with the control group, the hyperthyroid patients had a higher mean symptom score of frequency (1.15 ± 1.75 vs 0.31 ± 1.05, P = .01), incomplete emptying (0.91 ± 1.47 vs 0.29 ± 1.12, P = .02), straining (1.05 ± 0.85 vs 0.27 ± 0.51, P Hyperthyroid women demonstrated a lower mean peak flow rate (25.0 ± 5.3 vs 28.6 ± 6.1 mL/s, P = .02). After treatment, both LUTS and flow rates improved significantly. The severity of LUTS was associated with neither serum levels of thyroid hormone nor other hyperthyroid symptoms. Hyperthyroid women have worse LUTS and lower peak flow rates than healthy controls. However, the severity of LUTS is only mild (IPSS hyperthyroidism. The exact mechanisms of LUTS and/or lower urinary tract dysfunction in hyperthyroidism require further investigation. Copyright © 2011 Elsevier Inc. All rights reserved.

    Melanomas of the female genital tract present a unique clinical challenge. Not only are these lesions in an anatomically sensitive area, but also they tend to be multifocal and have high recurrence rates. Furthermore, several benign melanocytic proliferations resemble early-stage melanoma clinically and/or histopathologically. Thus, there is a significant need for additional tools that can help correctly diagnose and stage these lesions. Here, we quantitatively and nondestructively analyze the chemical composition of melanin in excised pigmented lesions of the female genital tract using pump-probe microscopy, a high-resolution optical imaging technique that is sensitive to many biochemical properties of melanin. Thirty-one thin (~5 μm) tissue sections previously excised from female genital tract melanocytic lesions were imaged with pump-probe microscopy and analyzed. We find significant quantitative differences in melanin type and structure between melanoma and nonmalignant melanocytic proliferations. Our analysis also suggests a link between the molecular signatures of melanins and lesion-specific genetic mutations. Finally, significant differences are found between metastatic and nonmetastatic melanomas. The limitations of this work include the fact that molecular information is restricted to melanin pigment and the sample size is relatively small. Pump-probe microscopy provides unique information regarding the biochemical composition of genital tract melanocytic lesions, which can be used to improve the diagnosis and staging of vulvar melanomas.

    Full Text Available Zika virus (ZIKV is a mosquito-transmitted virus that can cause severe defects in an infected fetus. ZIKV is also transmitted by sexual contact, although the relative importance of sexual transmission is unclear. To better understand the role of sexual transmission in ZIKV pathogenesis, a nonhuman primate (NHP model of vaginal transmission was developed. ZIKV was readily transmitted to mature cycling female rhesus macaque (RM by vaginal inoculation with 104-106 plaque-forming units (PFU. However, there was variability in susceptibility between the individual RM with 1->8 vaginal inoculations required to establish infection. After treatment with Depoprovera, a widely used contraceptive progestin, two RM that initially resisted 8 vaginal ZIKV inoculations became infected after one ZIKV inoculation. Thus, Depoprovera seemed to enhance susceptibility to vaginal ZIKV transmission. Unexpectedly, the kinetics of virus replication and dissemination after intravaginal ZIKV inoculation were markedly different from RM infected with ZIKV by subcutaneous (SQ virus inoculation. Several groups have reported that after SQ ZIKV inoculation vRNA is rapidly detected in blood plasma with vRNA less common in urine and saliva and only rarely detected in female reproductive tract (FRT secretions. In contrast, in vaginally inoculated RM, plasma vRNA is delayed for several days and ZIKV replication in, and vRNA shedding from, the FRT was found in all 6 animals. Further, after intravaginal transmission ZIKV RNA shedding from FRT secretions was detected before or simultaneously with plasma vRNA, and persisted for at least as long. Thus, ZIKV replication in the FRT was independent of, and often preceded virus replication in the tissues contributing to plasma vRNA. These results support the conclusion that ZIKV preferentially replicates in the FRT after vaginal transmission, but not after SQ transmission, and raise the possibility that there is enhanced fetal infection and

    Full Text Available Objective: Aim of this study is to evaluate the efficacy of a phytotherapic which includes Solidago, Orthosiphon and Birch extract (Cistimev® in association with antibiotic prophylaxis in female patients affected by recurrent urinary tract infections (UTIr. Materials and methods: Patients affected by UTIr older than 18 years started a 3-months antibiotic prophylaxis (Prulifloxacin 600 mg, 1 cps/week or Phosphomicyn 1 cachet/week according to antibiogram after urine culture. The patients were divided in 2 groups: Group A: antibiotic prophylaxis plus phytotherapy (1 cps/die for 3 months and Group B: antibiotic prophylaxis alone. Results: 164 consecutive patients were studied: 107 were included in group A (mean age 59 ± 17.3 years and 57 (mean age 61 ± 15.7 in group B. During the treatment period the relapse frequencies between the two groups were not significantly different (p = 0.854: 12/107 (11.21% patients interrupted the treatment for UTIr in group A and 6/57 (10.52% in group B. In the long term follow-up the relapse UTI risk was significant different in the two groups with a relapse risk 2.5 greater in group B than in group A (p < 0.0001. Conclusion: Our study demonstrated that in female patients affected by recurrent UTI, the association between antibiotic prophylaxis and of a phytotherapic which includes Solidago, Orthosiphon and Birch extract reduced the number of UTI in the 12 months following the end of prophylaxis and obtained a longer relapsing time, greatly improving the quality of life of the patients.

Further, after intravaginal transmission ZIKV RNA shedding from FRT secretions was detected before or simultaneously with plasma vRNA, and persisted for at least as long. Thus, ZIKV replication in the FRT was independent of, and often preceded virus replication in the tissues contributing to plasma vRNA. These results support the conclusion that ZIKV preferentially replicates in the FRT after vaginal transmission, but not after SQ transmission, and raise the possibility that there is enhanced fetal infection and pathology

    Melanoma of the vulva is the second most common type of malignancy afflicting that organ. This disease caries poor prognosis, and shows tendencies to recur locally and develop distant metastases through hematogenous dissemination. Further, there exists significant clinical overlap between early-stage melanomas and melanotic macules, benign lesions that are believed to develop in about 10% of the general female population. In this work we apply a novel nonlinear optical method, pump-probe microscopy, to quantitatively analyze female genitalia tract melanocytic lesions. Pump-probe microscopy provides chemical information of endogenous pigments by probing their electronic excited state dynamics, with subcellular resolution. Using unstained biopsy sections from 31 patients, we find significant differences between melanin type and structure in tissue regions with invasive melanoma, melanoma in-situ and non-malignant melanocytic proliferations (e.g., nevi, melanocytic macules). The molecular images of non-malignant lesion have a well-organized structure, with relatively homogenous pigment chemistry, most often consistent with that of eumelanin with large aggregate size or void of metals, such as iron. On the other hand, pigment type and structure observed in melanomas in-situ and invasive melanomas is typically much more heterogeneous, with larger contributions from pheomelanin, melanins with larger metal content, and/or melanins with smaller aggregate size. Of most significance, clear differences can be observed between melanocytic macules and vulvar melanoma in-situ, which, as discussed above, can be difficult to clinically distinguish. This initial study demonstrates pump-probe microscopy's potential as an adjuvant diagnostic tool by revealing systematic chemical and morphological differences in melanin pigmentation among invasive melanoma, melanoma in-situ and non-malignant melanocytic lesions.

    The study uniquely described the clinical value of transabdominal ultrasonography for monitoring features characterizing the estrous cycle in female cheetahs (Acinonyx jubatus). The reproductive tracts of 21 female, nulliparous, and relatively aged (median: 11 and interquartile range: 9.25-14 years) captive cheetahs resident on two sites in Namibia were assessed by transabdominal ultrasound. Subsequently, the ovarian findings on ultrasound were compared with direct visualization while performing laparoscopic sterilization. A combination of these observations supported by concurrent sampling for vaginal cytology and serum progesterone concentrations defined the estrous status of individual animals. At one site, six cheetahs had been implanted with the GnRH agonist, deslorelin as a contraceptive at least once within the preceding 11 years. On ultrasound, 31 uterine horns and 35 ovaries with discernible structures on 28 (86%) were visualized in the 21 cheetahs. The uterine body was difficult to visualize because of its intrapelvic location. Eleven of 19 uteri (58%) visualized showed endometrial edema suggestive of estrogenization. The uteri of four cheetahs (19%) showed evidence of mild cystic endometrial hyperplasia. Paraovarian cysts were seen on ultrasound (n = 21) and laparoscopy (n = 26) in 16 (76.2%) and 18 (85.7%) cheetahs, respectively. Ovarian volumes obtained from ultrasonographically determined dimensions predicted cyclic activity. Laparoscopy showed that 19 ovaries had discernible follicular structures. In the study population, 10 (47.6%) cheetahs were in proestrus or estrus; none in the luteal phase; and 11 (52.4%) in anestrus. Transabdominal ultrasound, in combination with serum progesterone concentrations and vaginal cytology, was used with acceptable accuracy to assess cyclic ovarian activity in captive cheetahs. A considerable proportion of this aged population showed ovarian activity and the prevalence of paraovarian cysts was notable. A

    The female reproductive tract (FRT) is a major site for human immunodeficiency virus (HIV) infection. There currently exists a poor understanding of how the innate immune system is activated upon HIV transmission and how this activation may affect systemic spread of HIV from the FRT. However, multiple mechanisms for how HIV is sensed have been deciphered using model systems with cell lines and peripheral blood-derived cells. The aim of this review is to summarize recent progress in the field of HIV innate immune sensing and place this in the context of the FRT. Because HIV is somewhat unique as an STD that thrives under inflammatory conditions, the response of cells upon sensing HIV gene products can either promote or limit HIV infection depending on the context. Future studies should include investigations into how FRT-derived primary cells sense and respond to HIV to confirm conclusions drawn from non-mucosal cells. Understanding how cells of the FRT participate in and effect innate immune sensing of HIV will provide a clearer picture of what parameters during the early stages of HIV exposure determine transmission success. Such knowledge could pave the way for novel approaches for preventing HIV acquisition in women.

    Laser-induced fluorescence (LIF) was studied in vivo from premalignant and benign lesions in the female genital tract, in particular the cervix. The aim of the study was to investigate the possibilities to differentiate cervical intraepithelial neoplasia (CIN) from normal tissue by means of two different fluorescence modalities. Most of the patients were given a low dose (5 mg/kg bw) of (delta) -amino levulinic acid (ALA). The ALA was orally administered 2 - 4 hours prior to the investigation. During this time, the ALA is transformed to the strongly fluorescent protoporphyrin IX (PpIX) via the haem cycle. Excitation light with a wavelength of 405 nm was used to excite the PpIX fluorescence. Excess amounts of PpIX were accumulated preferentially in diseased tissue. However, the variability in the PpIX accumulation from patient to patient was large. By using excitation light at 337 nm, the endogenous fluorophores are more efficiently excited. Therefore, this excitation modality was exploited for studying spectral characteristics of the autofluorescence in different tissue types. The spectra obtained were evaluated by forming fluorescence intensity ratios. The tissue types were grouped according to the histopathological examination. A correlation with the fluorescence ratios was performed. Some problems with the classification remain, mostly due to the difficulties in obtaining histopathologic evaluation of the biopsies at the exact location of the LIF measurements.

    Full Text Available The mechanism(s by which bacterial communities impact susceptibility to infectious diseases, such as HIV, and maintain female genital tract (FGT health are poorly understood. Evaluation of FGT bacteria has predominantly been limited to studies of species abundance, but not bacterial function. We therefore sought to examine the relationship of bacterial community composition and function with mucosal epithelial barrier health in the context of bacterial vaginosis (BV using metaproteomic, metagenomic, and in vitro approaches. We found highly diverse bacterial communities dominated by Gardnerella vaginalis associated with host epithelial barrier disruption and enhanced immune activation, and low diversity communities dominated by Lactobacillus species that associated with lower Nugent scores, reduced pH, and expression of host mucosal proteins important for maintaining epithelial integrity. Importantly, proteomic signatures of disrupted epithelial integrity associated with G. vaginalis-dominated communities in the absence of clinical BV diagnosis. Because traditional clinical assessments did not capture this, it likely represents a larger underrepresented phenomenon in populations with high prevalence of G. vaginalis. We finally demonstrated that soluble products derived from G. vaginalis inhibited wound healing, while those derived from L. iners did not, providing insight into functional mechanisms by which FGT bacterial communities affect epithelial barrier integrity.

    Worldwide, HIV-1 infects millions of people annually, the majority of whom are women. To establish infection in the female reproductive tract (FRT), HIV-1 in male ejaculate must overcome numerous innate and adaptive immune factors, traverse the genital epithelium, and establish infection in underlying CD4+ target cells. How the virus achieves this remains poorly defined. By utilizing a new technique, we define how HIV-1 interacts with different tissues of the FRT using human cervical explants and in vivo exposure in the rhesus macaque vaginal transmission model. Despite previous claims of the squamous epithelium being an efficient barrier to virus entry, we reveal that HIV-1 can penetrate both intact columnar and squamous epithelial barriers to depths where the virus can encounter potential target cells. In the squamous epithelium, we identify virus entry occurring through diffusive percolation, penetrating areas where cell junctions are absent. In the columnar epithelium, we illustrate that virus does not transverse barriers as well as previously thought due to mucus impediment. We also show a statistically significant correlation between the viral load of inocula and the ability of HIV-1 to pervade the squamous barrier. Overall, our results suggest a diffusive percolation mechanism for the initial events of HIV-1 entry. With these data, we also mathematically extrapolate the number of HIV-1 particles that penetrate the mucosa per coital act, providing a biological description of the mechanism for HIV-1 transmission during the acute and chronic stages of infection.

    While the main reproduction aim of semen is the transport of spermatozoa to the female genital tract, seminal plasma is a complex fluid that also carries a broad array of immunologically active molecules. Seminal plasma has been shown to contain a diverse array of anti-inflammatory and pro-inflammatory soluble mediators that regulate immune responses within the female reproductive tract than can facilitate fertilization. Since the natural inflammatory response to semen deposition in the female genital tract may result in recruitment of activated HIV target cells into the female genital mucosa, we discuss the constituents of semen that may increase the risk for HIV infection in women.

    Full Text Available Antimycobacterial chemotherapy is the mainstay of treatment for the majority of patients with genitourinary tuberculosis (GUTB. A large body of evidence from clinical trials suggests that short-course chemotherapy regimens, employing four drugs including rifampicin and pyrazinamide, achieve cure in most of the patients with tuberculosis (TB and are associated with the lowest rates of relapse. Standard six-month regimens are adequate for the treatment of GUTB. Directly observed treatment, short-course (DOTS is the internationally recommended comprehensive strategy to control TB, and directly observed treatment is just one of its five elements. DOTS cures not only the individual with TB but also reduces the incidence of TB as well as the prevalence of primary drug-resistance in the community. Corticosteroids have no proven role in the management of patients with GUTB. Errors in prescribing anti-TB drugs are common in clinical practice. Standardized treatment regimens at correct doses and assured completion of treatment have made DOTS the present-day standard of care for the management of all forms of TB including GUTB.

    The antibody response in serum and the reproductive tract of female rabbits to a model antigen, influenza virus haemagglutinin (HA), encoded by a recombinant myxoma virus was investigated. Strong and lasting IgG antibody responses to HA were induced in serum following intradermal, intranasal, and intravaginal immunisations. HA IgG was also detected in reproductive tract fluids but was only about 1% the titer of that in serum. HA IgA was not detected in serum of any infected groups and was occasionally detected in reproductive tract fluids at a low titer only after infections through mucosal sites. HA IgM was also detected only in some of the reproductive tract fluids at very low levels. Induction of ovulation did not change these patterns and B cell homing to the reproductive tract was not profound. In contrast, HA IgG and IgM titers in ovarian follicular fluids were comparable to that in serum. These data suggest that if this virus is used to deliver an immunocontraceptive vaccine that requires a high-level antibody response, the target antigen needs to be accessible to serum antibody or in the ovary

    To better understand the immunology of pregnancy, study of female genital tract fluid (FGF) is desirable. However the optimum method of collection of FGF in pregnant women for immunological methods, specifically cytokine measurement, is unknown. A prospective study of HIV-uninfected pregnant women comparing two methods of FGF collection: polyvinyl acetal sponge collection of cervical fluid (CF) and menstrual cup collection of cervicovaginal fluid (CVF). Samples were collected at 3 time points across the second and third trimesters: 14-21, 22-25 and 26-31 weeks. Multiplex chemi-luminescent assays were used to measure: IFN-γ, IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12, IL-13 and TNF-α. Optimal methodology for cytokine normalisation (sample weight, volume and total protein) was explored. All cytokines were measurable in both fluid types. IL-1β, IL-8 and IL-6 were detected at the highest concentrations (ranking order CF > CVF > plasma). CVF collection was simpler, provided the largest volume of sample (median 0.5 g) with the potential for undiluted usage, and allowed for self-insertion. CF cytokine concentrations were intrinsically associated with sample weight and protein concentration however CVF cytokines were independent of these. Both methods of collection are robust for measurement of FGF cytokines during pregnancy. We recommend CVF collection using a menstrual cup as a viable option in pregnant women for high dimensional biological techniques. Copyright © 2018 The Authors. Published by Elsevier B.V.

    Full Text Available In fertile women, the endometrium undergoes regular cycles of tissue build-up and regression. It is likely that uterine stem cells are involved in this remarkable turn over. The main goal of our current investigations was to identify slow-cycling (quiescent endometrial stem cells by means of a pulse-chase approach to selectively earmark, prospectively isolate, and characterize label-retaining cells (LRCs. To this aim, transgenic mice expressing histone2B-GFP (H2B-GFP in a Tet-inducible fashion were administered doxycycline (pulse which was thereafter withdrawn from the drinking water (chase. Over time, dividing cells progressively loose GFP signal whereas infrequently dividing cells retain H2B-GFP expression. We evaluated H2B-GFP retaining cells at different chase time points and identified long-term (LT; >12 weeks LRCs. The LT-LRCs are negative for estrogen receptor-α and express low levels of progesterone receptors. LRCs sorted by FACS are able to form spheroids capable of self-renewal and differentiation. Upon serum stimulation spheroid cells are induced to differentiate and form glandular structures which express markers of mature műllerian epithelial cells. Overall, the results indicate that quiescent cells located in the distal oviduct have stem-like properties and can differentiate into distinct cell lineages specific of endometrium, proximal and distal oviduct. Future lineage-tracing studies will elucidate the role played by these cells in homeostasis, tissue injury and cancer of the female reproductive tract in the mouse and eventually in man.

    Full Text Available BACKGROUND: Measurement of immune mediators and antimicrobial activity in female genital tract secretions may provide biomarkers predictive of risk for HIV-1 acquisition and surrogate markers of microbicide safety. However, optimal methods for sample collection do not exist. This study compared collection methods. METHODS: Secretions were collected from 48 women (24 with bacterial vaginosis [BV] using vaginal and endocervical Dacron and flocked swabs. Cervicovaginal lavage (CVL was collected with 10 mL of Normosol-R (n = 20, saline (n = 14, or water (n = 14. The concentration of gluconate in Normosol-R CVL was determined to estimate the dilution factor. Cytokine and antimicrobial mediators were measured by Luminex or ELISA and corrected for protein content. Endogenous anti-HIV-1 and anti-E. coli activity were measured by TZM-bl assay or E. coli growth. RESULTS: Higher concentrations of protein were recovered by CVL, despite a 10-fold dilution of secretions, as compared to swab eluents. After protein correction, endocervical swabs recovered the highest mediator levels regardless of BV status. Endocervical and vaginal flocked swabs recovered significantly higher levels of anti-HIV-1 and anti-E. coli activity than Dacron swabs (P<0.001. BV had a significant effect on CVL mediator recovery. Normosol-R tended to recover higher levels of most mediators among women with BV, whereas saline or water tended to recover higher levels among women without BV. Saline recovered the highest levels of anti-HIV-1 activity regardless of BV status. CONCLUSIONS: Endocervical swabs and CVL collected with saline provide the best recovery of most mediators and would be the optimal sampling method(s for clinical trials.

    A study was conducted to establish whether Trypanosoma brucei migrated preferentially to the reproductive tracts of female BKA mice, or Hooded Lister rats and lodged there as the site of choice compared to other organs. Blood flow to the reproductive tracts, the liver and spleen was measured using red blood cells labelled with chromium- 51. The distribution of trypanosomes labelled with 75 Se-methionine. The average percentage of the blood flow to the reproductive tract was 0.21Plus or minus0.08 in mice, while the mean concentration of trypanosomes there was 0.30% in both mice and rats. Blood flow to the liver was lower than the percentage distribution of Se-labelled T.Brucei(5.17Plus or minus1.34 versus 8.1Plus or Minus1.2). There were, on the contrary, less labelled trypanosomes as compared to the mean blood flow to the spleen (0.54% plus or minus0.18 versus 2.10%pPlus or minus0.88). After 24 hours there were adequate numbers of T. brucei in the reproductive tract to cause parasitaemia in recipient mice. From these preliminary data it was concluded that T. brucei did not lodge in the reproductive organ system a site of choice. (author). 9 refs., 3 tabs

    The aim of this study was to evaluate the psychometric properties of the Persian version of the International Consultation on Incontinence Modular Questionnaire for Female Lower Urinary Tract Symptoms (ICIQ-FLUTS) in patients with urinary tract dysfunction. After gaining permission from the International Consultation on Incontinence Modular Questionnaire (ICIQ) advisory board, the English Female Lower Urinary Tract Symptoms (FLUTS) questionnaire was translated into Persian and then translated back into English. One hundred fourteen women with pelvic floor dysfunction were asked to complete the Persian FLUTS and International Consultation on Incontinence Modular Questionnaire Overactive Bladder Questionnaire (ICIQ-OAB). The Persian FLUTS questionnaire was also readministered to 20 patients 2 weeks after their initial visit. Study data were analyzed using SPSS V16.0. To validate the translated questionnaire, we assayed content/face validity, internal consistency/reliability, and construct validity. Internal consistency and test-retest reliability were assessed using Cronbach's alpha and the intraclass correlation coefficient (ICC) respectively. The mean age of the patients was 48.8 years old, 84% were married, and 59% had at least one Caesarean. Except for very few missing data, there is no any ambiguity in the Persian version of the FLUTS questionnaire. The Cronbach's alpha was 0.83, indicating a high internal consistency. Concerning criterion validity, correlation between the Persian FLUTS and the OAB was 0.77 (p Persian version of the FLUTS questionnaire demonstrates good internal consistency, content validity, and reliability.

    The 2 major functions of the lower urinary tract are the storage and emptying of urine. These processes are controlled by complex neurophysiologic mechanisms and are subject to injury and disease. When there is disruption of the neurologic control centers, dysfunction of the lower urinary tract may occur. This is sometimes referred to as the "neurogenic bladder." The manifestation of dysfunction depends on the level of injury and severity of disruption. Patients with lesions above the spinal cord often have detrusor overactivity with no disruption in detrusor-sphincter coordination. Patients with well-defined suprasacral spinal cord injuries usually present with intact reflex detrusor activity but have detrusor sphincter dyssynergia, whereas injuries to or below the sacral spinal cord usually lead to persistent detrusor areflexia. A complete gynecologic, urologic, and neurologic examination should be performed when evaluating patients with neurologic lower urinary tract dysfunction. In addition, urodynamic studies and neurophysiologic testing can be used in certain circumstances to help establish diagnosis or to achieve better understanding of a patient's vesicourethral functioning. In the management of neurogenic lower urinary tract dysfunction, the primary goal is improvement of a patient's quality of life. Second to this is the prevention of chronic damage to the bladder and kidneys, which can lead to worsening impairment and symptoms. Treatment is often multifactorial, including behavioral modifications, bladder training programs, and pharmacotherapy. Surgical procedures are often a last resort option for management. An understanding of the basic neurophysiologic mechanisms of the lower urinary tract can guide providers in their evaluation and treatment of patients who present with lower urinary tract disorders. As neurologic diseases progress, voiding function often changes or worsens, necessitating a good understanding of the underlying physiology in question.

    Introduction Appendicitis is a prevailing cause of acute abdomen, but is often difficult to diagnose due to its wide range of symptoms, anatomical variations, and developmental abnormalities. Urological disorders of the genitourinary tract may be closely related to appendicitis due to the close proximity of the appendix to the genitourinary tract. This review provides a summary of the urological complications and simulations of appendicitis. Both typical and urological symptoms of appendicitis are discussed, as well as recommended diagnostic and treatment methods. Methods Medline searches were conducted via PubMed in order to incorporate data from the recent and early literature. Results Urological manifestations of appendicitis affect the adrenal glands, kidney, retroperitoneum, ureter, bladder, prostate, scrotum, and penis. Appendicitis in pregnancy is difficult to diagnose due to variations in appendiceal position and trimester-specific symptoms. Ultrasound, CT, and MRI are used in diagnosis of appendicitis and its complications. Treatment of appendicitis may be done via open appendectomy or laparoscopic appendectomy. In some cases, other surgeries are required to treat urological complications, though surgery may be avoided completely in other cases. Conclusion Clinical presentation and complications of appendicitis vary among patients, especially when the genitourinary tract is involved. Appendicitis may mimic urological disorders and vice versa. Awareness of differential diagnosis and proper diagnostic techniques is important in preventing delayed diagnosis and possible complications. MRI is recommended for diagnosis of pregnant patients. Ultrasound is preferred in patients exhibiting typical symptoms. PMID:28413377

    T helper type 17 (Th17) cells play an important role in immunity to fungal and bacterial pathogens, although their role in the female genital tract, where exposure to these pathogens is common, is not well understood. We investigated the relationship between female genital tract infections, cervicovaginal interleukin-17 (IL-17) concentrations and Th17 cell frequencies. Forty-two cytokines were measured in cervicovaginal lavages from HIV-uninfected and HIV-infected women. Frequencies of Th17 cells (CD3(+) CD4(+) IL-17a(+)) were evaluated in cervical cytobrushes and blood by flow cytometry. Women were screened for Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Trichomonas vaginalis and herpes simplex virus 2 by PCR, and candidal infections and bacterial vaginosis by Gram stain. Women with bacterial sexually transmitted infections (STIs), specifically chlamydia and gonorrhoea, had higher genital IL-17 concentrations than women with no STI, whereas women with candidal pseudohyphae/spores had lower IL-17 concentrations compared with women without candidal infections. Viral STIs (herpes simplex virus 2 and HIV) were not associated with significant changes in genital IL-17 concentrations. Genital IL-17 concentrations correlated strongly with other inflammatory cytokines and growth factors. Although Th17 cells were depleted from blood during HIV infection, cervical Th17 cell frequencies were similar in HIV-uninfected and HIV-infected women. Cervical Th17 cell frequencies were also not associated with STIs or candida, although few women had a STI. These findings suggest that IL-17 production in the female genital tract is induced in response to bacterial but not viral STIs. Decreased IL-17 associated with candidal infections suggests that candida may actively suppress IL-17 production or women with dampened IL-17 responses may be more susceptible to candidal outgrowth. © 2015 John Wiley & Sons Ltd.

    Interleukin-8 (IL-8, CXCL8) plays important roles in immune responses at mucosal sites including in the lower genital tract. Since several types of bacteria produce proteases that cleave IL-8 and many types of bacteria can be present in lower genital tract microbiota, we assessed genital fluids for IL-8 cleavage/alteration. Genital fluids collected by lavage from 200 women (23 HIV-seronegative and 177 HIV-seropositive) were tested for IL-8 cleavage/alteration by ELISA. IL-8 cleaving/altering activity was observed in fluids from both HIV-positive (28%) and HIV-negative women (35%). There was no clear relationship between the activity and the types of bacteria present in the lower genital tract as determined by high-throughput sequencing of the 16S rRNA gene. Protease inhibitors specific for matrix metalloproteinases (MMPs) reduced the activity and a multiplex assay that detects both inactive and active MMPs showed the presence of multiple MMPs, including MMP-1, -3, -7, -8, -9, -10 and -12 in genital secretions from many of the women. The IL-8-cleaving/altering activity significantly correlated with active MMP-9 as well as with cleavage of a substrate that is acted on by several active MMPs. These studies show that multiple MMPs are present in the genital tract of women and strongly suggest that MMP-9 in genital secretions can cleave IL-8 at this mucosal site. These studies suggest that MMP-mediated cleavage of IL-8 can modulate inflammatory responses in the lower genital tract.

    Plasma HIV RNA is the most significant determinant of cervical HIV shedding. However, shedding is also associated with sexually transmitted infections (STIs) and cervical inflammation. The mechanism by which this occurs is poorly understood. There is evidence that systemic immune activation promotes viral entry, replication, and HIV disease progression. We hypothesized that systemic immune activation would be associated with an increase in HIV genital shedding. Clinical assessments, HIV RNA in plasma and genital secretions, and markers of immune activation (CD38(+)DR(+) and CD38(-)DR(-)) on CD4(+) and CD8(+) T cells in blood were evaluated in 226 HIV+ women enrolled in the Women's Interagency HIV Study. There were 569 genital evaluations of which 159 (28%) exhibited HIV RNA shedding, defined as HIV viral load >80 copies per milliliter. We tested associations between immune activation and shedding using generalized estimating equations with logit link function. In the univariate model, higher levels of CD4(+) and CD8(+) T-cell activation in blood were significantly associated with genital tract shedding. However, in the multivariate model adjusting for plasma HIV RNA, STIs, and genital tract infections, only higher levels of resting CD8(+) T cells (CD38(-)DR(-)) were significantly inversely associated with HIV shedding in the genital tract (odds ratios = 0.44, 95% confidence interval: 0.21 to 0.9, P = 0.02). The association of systemic immune activation with genital HIV shedding is multifactorial. Systemic T-cell activation is associated with genital tract shedding in univariate analysis but not when adjusting for plasma HIV RNA, STIs, and genital tract infections. In addition, women with high percentage of resting T cells are less likely to have HIV shedding compared with those with lower percentages. These findings suggest that a higher percentage of resting cells, as a result of maximal viral suppression with treatment, may decrease local genital activation, HIV

    Numerous studies have shown contradictory variable percentages of recurrent HPV lesions, after various therapies. The present study therefore evaluates the effectiveness of CO2 laser vaporization in the treatment of single-site HPV lesions of the lower female genital tract in order to confirm the conviction that physical therapy alone, in agreement with some findings reported in the literature, is capable of guaranteeing a high cure rate in selected patients. From January 1995 to June 1996, seventy- five female patients were treated with CO2 laser vaporization for single-site genital HPV lesions, some of which were associated with low-grade intra-epithelial neoplasia. The success rate after 12 months proved to be 97%. The pre-existing clinical symptoms disappeared in all the patients treated. No complication in the vaporization procedure was encountered.

  15. First reported case of fulminant TB with progression of infection from lungs to the genitourinary region

    Tatjana Adzic-Vukicevic

    Full Text Available ABSTRACT Although tuberculosis (TB is a curable disease, it continues to be one of the leading infections associated with death in the world. Extra-pulmonary TB (EPTB occurs in approximately 10% of the total cases, presenting with lymph nodes, pleura, bone and genitourinary tract as the most common locations. Genitourinary tuberculosis, the second most common EPTB, is very difficult to diagnose unless there is a high index of suspicion. Isolated TB orchitis or prostatitis without clinical evidence of renal involvement is a rare entity among genitourinary tuberculosis. We presented the first reported case of TB prostatitis and orchitis associated with pulmonary TB and the presence of an acute massive caseous pneumonia in an immunocompetent man. Despite the anti-TB therapy, the patient presented a rapid progression of disease and deterioration of general conditions taking to death, which occurred four days after TB treatment had started. Disseminated TB is a relatively uncommon cause of acute massive caseous pneumonia; however, there should always be suspicion of the disease, since it is a potentially treatable cause. This rare case supports the assertion that TB should be considered as an important differential diagnosis of genitourinary tumors irrespective of evidence of active TB elsewhere in the body.

  16. Drosophila sperm swim backwards in the female reproductive tract and are activated via TRPP2 ion channels.

    Directory of Open Access Journals (Sweden)

    Michael Köttgen

    Full Text Available Sperm have but one purpose, to fertilize an egg. In various species including Drosophila melanogaster female sperm storage is a necessary step in the reproductive process. Amo is a homolog of the human transient receptor potential channel TRPP2 (also known as PKD2, which is mutated in autosomal dominant polycystic kidney disease. In flies Amo is required for sperm storage. Drosophila males with Amo mutations produce motile sperm that are transferred to the uterus but they do not reach the female storage organs. Therefore Amo appears to be a mediator of directed sperm motility in the female reproductive tract but the underlying mechanism is unknown.Amo exhibits a unique expression pattern during spermatogenesis. In spermatocytes, Amo is restricted to the endoplasmic reticulum (ER whereas in mature sperm, Amo clusters at the distal tip of the sperm tail. Here we show that flagellar localization of Amo is required for sperm storage. This raised the question of how Amo at the rear end of sperm regulates forward movement into the storage organs. In order to address this question, we used in vivo imaging of dual labelled sperm to demonstrate that Drosophila sperm navigate backwards in the female reproductive tract. In addition, we show that sperm exhibit hyperactivation upon transfer to the uterus. Amo mutant sperm remain capable of reverse motility but fail to display hyperactivation and directed movement, suggesting that these functions are required for sperm storage in flies.Amo is part of a signalling complex at the leading edge of the sperm tail that modulates flagellar beating and that guides a backwards path into the storage organs. Our data support an evolutionarily conserved role for TRPP2 channels in cilia.

    Relatively little is known about the human T-cell response to herpes simplex virus type 2 (HSV-2) in the female genital tract, a major site of heterosexual HSV-2 acquisition, transmission, and reactivation. In order to understand the role of local mucosal immunity in HSV-2 infection, T-cell lines were expanded from serial cervical cytobrush samples from 30 HSV-2-infected women and examined for reactivity to HSV-2. Approximately 3% of the CD3+ T cells isolated from the cervix were HSV-2 specific and of these, a median of 91.3% were CD4+, whereas a median of 3.9% were CD8+. HSV-2-specific CD4+ T cells expanded from the cervix were not only more frequent than CD8+ T cells but also exhibited greater breadth in terms of antigenic reactivity. T cells directed at the same HSV-2 protein were often detected in serial cervical cytobrush samples and in blood. Thus, broad and persistent mucosal T-cell responses to HSV-2 were detected in the female genital tract of HSV-2+ women suggesting that these cells are resident at the site of HSV-2 infection. Understanding the role of these T cells at this biologically relevant site will be central to the elucidation of adaptive immune mechanisms involved in controlling HSV-2 disease.

    Full Text Available Abstract Background Chlamydia trachomatis is the most common sexually transmitted bacterial pathogen causing female genital tract infection throughout the world. Reinfection with the same serovar, as well as multiple infections with different serovars, occurs in humans. Using a murine model of female C. trachomatis genital tract infection, we determined if homotypic and/or heterotypic protection against reinfection was induced following infection with human oculogenital strains of C. trachomatis belonging to two serovars (D and H that have been shown to vary significantly in the course of infection in the murine model. Methods Groups of outbred CF-1 mice were reinfected intravaginally with a strain of either serovar D or H, two months after initial infection with these strains. Cellular immune and serologic status, both quantitative and qualitative, was assessed following initial infection, and the course of infection was monitored by culturing vaginal samples collected every 2–7 days following reinfection. Results Serovar D was both more virulent (longer duration of infection and immunogenic (higher level of circulating and vaginal IgG and higher incidence of IgA in vaginal secretions in the mouse genital tract. Although both serovars induced cross-reacting antibodies during the course of primary infection, prior infection with serovar H resulted in only a slight reduction in the median duration of infection against homotypic reinfection (p ~ 0.10, while prior infection with serovar D resulted in significant reduction in the median duration of infection against both homotypic (p Conclusion Serovar D infection resulted in significant homotypic and heterotypic protection against reinfection, while primary infection with serovar H resulted in only slight homotypic protection. In addition to being the first demonstration of acquired heterotypic immunity between human oculogenital serovars, the differences in the level and extent of this immunity

    Topical vaginal microbicides have been considered a promising option for preventing the male-to-female sexual transmission of HIV; however, clinical trials to date have not clearly demonstrated robust and reproducible effectiveness results. While multiple approaches may help enhance product effectiveness observed in clinical trials, increasing the drug exposure in lower genital tract tissues is a compelling option, given the difficulty in achieving sufficient drug exposure and positive correlation between tissue exposure and microbicide efficacy. Since many microbicide drug candidates are substrates of transporters and/or metabolizing enzymes, there is emerging interest in improving microbicide exposure and efficacy through local modulation of transporters and enzymes in the female lower genital tract. However, no systematic information on transporter/enzyme expression is available for ectocervical and vaginal tissues of premenopausal women, the genital sites most relevant to microbicide drug delivery. The current study utilized reverse transcriptase polymerase chain reaction (RT-PCR) to examine the mRNA expression profile of 22 transporters and 19 metabolizing enzymes in premenopausal normal human ectocervix and vagina. Efflux and uptake transporters important for antiretroviral drugs, such as P-gp, BCRP, OCT2, and ENT1, were found to be moderately or highly expressed in the lower genital tract as compared to liver. Among the metabolizing enzymes examined, most CYP isoforms were not detected while a number of UGTs such as UGT1A1 were highly expressed. Moderate to high expression of select transporters and enzymes was also observed in mouse cervix and vagina. The implications of this information on microbicide research is also discussed, including microbicide pharmacokinetics, the utilization of the mouse model in microbicide screening, as well as the in vivo functional studies of cervicovaginal transporters and enzymes.

    The objective of this study was to evaluate retrospectively the clinical characteristics, treatments, and outcomes of patients with primary diffuse large B-cell lymphoma (DLBCL) of the female genital tract. The basic characteristics, treatments, and outcomes of six patients diagnosed with primary DLBCL of the female genital tract, including the ovary, uterine cervix, and vagina, treated in our hospital between 2000 and 2012, were analyzed retrospectively. Seven of 323 (2.2 %) newly diagnosed DLBCLs were diagnosed as primary female genital tract DLBCL. Six patients with complete medical data were included in the analysis. The median age at diagnosis was 52.5 years (range 20-65). The presenting symptoms included abnormal vaginal bleeding, increased vaginal discharge, abdominal fullness, and abdominal pain. Two patients had stage IE disease and four patients had stage IIE disease. Treatment included chemotherapy only in five patients, and combined chemotherapy and localized radiation in one patient. After a median follow-up of 58 months, four patients showed relapse in the central nervous system and two had died from progressive disease. The median progression-free survival was 27 months and the median overall survival for this group has not been reached. Patients with primary female genital tract DLBCL may have poor outcomes and a high risk of central nervous system relapse. Central nervous system prophylaxis might be considered in addition to systemic chemotherapy for DLBCL of the female genital tract.

    Frozen section diagnosis provides critical information for immediate surgical management decision making. Over the last several years, there have been some significant advances in treatment of genitourinary cancer, particularly with regard to surgical techniques. These changes in turn impact the type and frequency of intraoperative frozen section requests. In this review, we describe the main indications and diagnostic challenges of frozen section diagnosis during surgeries of each genitourinary organ system including prostate, kidney, bladder, testis, and penis. The pitfalls and approaches to different diagnostic situations are discussed. It is also stressed that pathologists must not only be familiar with the histological diagnosis, but also understand the limitations of frozen section diagnosis and communicate with urologists during the intraoperative treatment decision making process.

  4. Primary malignant melanoma of the female urethra: Report of a rare neoplasm of the urinary tract

    Directory of Open Access Journals (Sweden)

    Namita Bhutani

    Full Text Available Introduction: Melanoma is a malignant tumor that can affect any area of the anatomical economy. Its occurance in the female urethra is extremely rare. We report a case of primary malignant urethral melanoma developed in an elderly female patient. Presentation of case: A 70 years old female presented with dysuria, poor stream, gross haematuria, intermittent blood spots, and a painful mass. On physical examination, there were no suspicious lesions on the skin. On external genital examination, a lesion at the level of the urethral meatus was observed. The mass was removed by wide local excision under spinal anaesthesia. The pathological diagnosis was malignant melanoma of the urethra. Discussion: The common presentations include bleeding and/or discharge per urethra, voiding dysfunction and the presence of tumor mass. Survival depends on the stage, location and size of the neoplasm at the time of diagnosis. Despite major surgery, radiotherapy or immunotherapy; malignant melanoma usually has a poor prognosis. Conclusion: Melanoma of the female urethra is an extremely uncommon pathology leading to paucity of literature and any definite recommendations regarding management. The histological and immunohistochemical findings can be helpful in making an early and accurate diagnosis of malignant melanoma in the urogenital region.

    2012-12-01

    Full Text Available The phlogistic-infectious diseases of the lower female genital tract are one of the most widespread obstetricgynecologic issues, due to treatment failures that cause frequent relapses and to the adverse effects of some commonly used drugs.The most common vaginal syndromes are due to uncontrolled growth of bacteria or fungi which replace the normal vaginal flora, causing phlogistic and infectious based diseases. These infections are treated with anti-inflammatory and antibiotic therapy; however, the emergence of resistant strains and the ability of many microorganisms to grow inside biofilms severely reduce the repertoire of useful agents.Thus, in the last years increasing interest has been focused toward compounds of plant origin with anti-microbial properties. In the present work, we studied the antimicrobial activity of fractions obtained from endemic plants of Sardinia towards microorganisms that frequently are involved in vaginal infectious diseases: Streptococcus agalactiae, Gardnerella vaginalis and Candida albicans.

    The aim of this study was to characterize the clinically relevant genital tract disorders of dromedary camels. Reproductive tract examinations were performed via transrectal palpation, ultrasonography and vaginal exploration. The ultrasonic appearance of the reproductive pathology was described and compared with its morphology at laparotomy, after surgical removal, during postmortem examination or upon slaughter. Diagnosis was also confirmed by histopathology. The most frequently encountered follicular structures were larger than typical follicles (56/338, 16.6%) having three echo textures: 1) thin walls and clear hyperechogenic content (11.6%); 2) thick walls and few fibrous trabeculae (33.7%); and 3) thick walls and many echogenic transecting fibrinous strands (54.7%). Corpora lutea with non-echoic central cavity (5/31, 16.1%) were greater in diameter than those with no cavity (26/31, 83.9%) (P=0.03). A granulosa cell tumor (1/338, 0.3%) was multilocular and honeycombed in shape. Presence of a large, well-demarcated, hypoechogenic sac lateral to or beneath the uterine horn encasing the ovary was diagnostic for ovarian hydrobursitis (102/338, 30.2%). Hydrosalpinx and pyosalpinx (6/338, 1.8%) were beaded in appearance, with the ovary located outside these structures. Clinical endometritis/cervicitis (122, 36.1%) was characterized by changes in the homogeneity in about half of the cases. A greatly dilated uterus with clear, hypoechogenic or echogenic contents with signs of hydrometra and pyometra, respectively, was another categorization of a reproductive pathology (24/338, 7.1%). Highly reflective, linear structures were observed in cases with intrauterine fetal bone retention (1/338, 0.3%). In conclusion, reproductive pathologies in dromedary camels can be efficiently imaged by use of ultrasonic technologies, thus familiarizing the practitioner with these disorders and facilitating application of these technologies so that suitable treatment can occur is important

    Full Text Available The morphology of the reproductive tract of Podisus nigrispinus (Dallas females fed with Alabama argillacea (Hübner larvae, artificial diet, Tenebrio molitor L. larvae or Musca domestica L. larvae were studied. The reproductive tract of females of this species presented yellow coloration and independent of the diet, each ovary had seven ovarioles joined through terminal filaments and forming a bunch shape structure. The histological data revealed that the ovary of P. nigrispinus was of meroistic telotrophic type, with each individual ovariole divided in a terminal filament, a tropharium (trophic chamber, a vitellarium, and a pedicel. The prey type affected the development and morphometry of these structures. Females of P. nigrispinus fed with 3rd or 5th instar larvae of cotton leafworm (A. argillacea presented developed ovaries with ovarioles showing a great number of oocytes in advanced stages of development. Females fed with artificial diet presented atrophic ovaries and ovarioles practically without oocytes. Females fed with T. molitor or M. domestica showed ovaries in intermediary stage of development. The central ovariole was longer in females fed with 5th instar larvae of cotton leafworm and shorter in those fed with artificial diet. Most developed oocytes were observed in ovaries of females fed with 5th or 3rd instar larvae of cotton leafworm, and the majority of atrophic oocytes were found in females fed with artificial diet.Este estudo apresenta a morfologia do sistema reprodutor feminino de Podisus nigrispinus (Dallas alimentado com larvas de Alabama argillacea (Hübner, Musca domestica L. e de Tenebrio molitor L. ou dieta artificial.

    Full Text Available The objective of this study was to describe the information that women with tubal infertility recalled having received from physicians when they consulted for a reproductive tract infection (RTI and the information physicians reported having provided to women consulting for RTIs. Interviews were conducted with 16 women presenting primary tubal infertility selected on the basis of purposeful sampling criteria. Also, 15 physicians working in the public health network in the city of Campinas, Brazil, were selected at random and interviewed. Analysis of the women's statements concerning previous RTI-related medical consultations showed that they did not recall having received any information on either prevention or the impact of RTI on their reproductive future. Analysis of interviews with physicians showed that the information they provided to women consulting for RTIs was incomplete and unclear. The information women recalled having received and that which physicians remembered having provided at the time of treating a patient with RTI was similar. In conclusion, these women lacked adequate or complete information and that it was probably not possible for them to adopt measures to avoid repetition of RTI and minimize risk of tubal infertility.

    This study was conducted to determine risk factors for infectious complications after urodynamic study (UDS) in women, which can assist clinicians in identifying high-risk subjects who would benefit from antibiotic prophylaxis before UDS. In this prospective cohort study, we studied 232 women who underwent UDS at Santa Casa de São Paulo School of Medical Sciences between June 2013 and June 2014. Women ranging in age from 26 to 84 years who had urinary incontinence, pelvic organ prolapse, or voiding dysfunction were required to collect urine samples at 7 days before, on the day of, and 3-5 days after UDS. Urine cultures with >100,000 CFU/mL were considered positive. Risk factors associated with bacteriuria and urinary tract infection (UTI) after UDS were evaluated using multivariate analysis with multiple logistic regression. Two hundred thirty-two out of 257 women were subjected to further analysis. The incidence of bacteriuria, transient bacteriuria, and UTI after UDS was 11.6%, 7.3%, and 4.3%, respectively. On multivariate analysis, hypothyroidism (P = .04), body mass index (BMI) >30 (P = .025), and advanced pelvic organ prolapse (P = .021) were associated with a significantly increased risk of bacteriuria; however, only BMI >30 (P = .02) was associated with an increased risk for UTI. The rate of infectious complications after UDS was low, and advanced pelvic organ prolapse and hypothyroidism increased the risk for bacteriuria. However, only BMI >30 was associated with bacteriuria and UTI after UDS. Copyright © 2015 Association for Professionals in Infection Control and Epidemiology, Inc. Published by Elsevier Inc.

    Sexually transmitted viruses cause chronic infections that have serious long-term health consequences. Based on the evidence from clinical and epidemiological studies, women carry a disproportionately higher burden of sexually transmitted diseases. The reasons for this are not well understood and possibly relate to a variety of social, behavioral and economic factors. In addition to these factors there are biological reasons that contribute to the higher prevalence in women. In this context it is critical to focus on and understand the local microenvironment of the female genital tract, since the majority of viral infections in women occur by heterosexual transmission. The genital tract is also the target site for initiation and maintenance of protective immune responses that could prevent or eliminate viral infections. The epithelial cells of the genital tract provide the first line of defense against viral entry. The interactions between each sexually transmitted virus and the genital epithelium are distinct and determine the outcome of exposure. They are also influenced by a number of factors in the local genital milieu. Among these factors are the female sex hormones that regulate both the susceptibility as well as immune responses to viral infections in the genital tract. Better understanding of the interactions of viruses with the local environment in the female genital tract will lead to development of novel methods to prevent sexually transmitted infections as well as to enhance innate and adaptive immunity.

    To determine the relationship between vaginal reflux (VR) and urinary tract infection (UTI) in female children aged UTI, who underwent a voiding cystourethrography (VCUG) for assessment of vesicoureteral reflux (VUR) at Sanggye Paik Hospital. Fifty-one girls, who underwent VCUG for assessment of congenital hydronephrosis or renal pelvis dilatation, without a UTI, formed the control group. The correlation between the presence and grade of VR and UTI was evaluated. The prevalence rate of VR was higher in the UTI (42.9%) than control (13.7%) group ( P UTI (mean, 0.64) than control (mean, 0.18) group ( P UTI group: n=126, age, 5.28±2.13 months; control group: n=22, age, 4.79±2.40 months; P =0.33), both VR prevalence (43.65% vs. 18.18%, P UTI than control group. Presence and higher grade of VR were associated with UTI recurrence ( P UTI, the risk of renal defect increases. Occurrence of VR is associated with UTI recurrence and urosepsis in pediatric female patients.

    Young African females are at an increased risk of HIV acquisition, and genital inflammation or the vaginal microbiome may contribute to this risk. We studied these factors in 168 HIV-negative South African adolescent females aged 16 to 22 years. Unsupervised clustering of 16S rRNA gene sequences revealed three clusters (subtypes), one of which was strongly associated with genital inflammation. In a multivariate model, the microbiome compositional subtype and hormonal contraception were significantly associated with genital inflammation. We identified 40 taxa significantly associated with inflammation, including those reported previously ( Prevotella , Sneathia , Aerococcus , Fusobacterium , and Gemella ) as well as several novel taxa (including increased frequencies of bacterial vaginosis-associated bacterium 1 [BVAB1], BVAB2, BVAB3, Prevotella amnii , Prevotella pallens , Parvimonas micra , Megasphaera , Gardnerella vaginalis , and Atopobium vaginae and decreased frequencies of Lactobacillus reuteri , Lactobacillus crispatus , Lactobacillus jensenii , and Lactobacillus iners ). Women with inflammation-associated microbiomes had significantly higher body mass indices and lower levels of endogenous estradiol and luteinizing hormone. Community functional profiling revealed three distinct vaginal microbiome subtypes, one of which was characterized by extreme genital inflammation and persistent bacterial vaginosis (BV); this subtype could be predicted with high specificity and sensitivity based on the Nugent score (≥9) or BVAB1 abundance. We propose that women with this BVAB1-dominated subtype may have chronic genital inflammation due to persistent BV, which may place them at a particularly high risk for HIV infection.

    Conclusion: This microarray chip was a rapid, easy, inexpensive and sensitive tool for detecting female lower genital tract Candida infection in a one-time vaginal sampling process, although the data on the four other pathogens were still unavailable. A larger population study is encouraged to test the validity of this multiplexed immunoassay chip.

    Is O2 tension in the pig oviduct and uterus affected by the estrous cycle stage and the animal's age, and can the outcome of in vitro embryo development be improved by mimicking these physiological values? O2 tension within the pig reproductive organs is affected by the animal's age, and values close to those measured in vivo have a positive impact on embryo development and quality when used during IVF and embryo culture (EC). To obtain a healthy embryo in vitro, it is necessary to adopt a culture microenvironment that approximates physiological conditions. Despite advances in surgical procedures and sensitive probes that allow accurate assessment of in vivo O2 tension, few such studies have been conducted recently in mammals. In addition, no reference values of physiological O2 tension in the reproductive tract exist for large animal models such as pig, and the effect of O2 tension on ART outcomes is unknown. This study was conducted in pigs. We measured oviductal and uterine O2 tension (n = 29 and 13 respectively) and then examined how the use of the physiological values in pig IVF and EC affected pig ART output (n = 1447 oocytes). The oviductal and uterine O2 tension at the different stages of the estrous cycle was monitored using a laparo-endoscopic single-site surgery (LESS) assisted approach along with a flexible and thin miniaturized luminescent probe. Two groups of pigs, Large-white x Landrace breed, were used: for the first group, 16 pre-pubertal gilts (5 months old and 95 kg) were induced to ovulate with equine chorionic gonadotropin (eCG) and human chorionic gonadotropin (hCG); in the second group 13 mature sows (24-48 months and 185 kg) were used. IVF and EC were performed at two different O2 tensions: Atmospheric O2 (20%) and the mean in vivo value measured (7%). At 18-20 hours post-insemination (hpi), a small sample of presumptive zygotes were fixed, stained, and examined under epifluorescence microscopy to assess the fertilization rates. At

    The use of transabdominal ultrasonography to assess the oestrous cycle has not been previously described in the African lion (Panthera leo). Twelve sexually mature lionesses and five female cubs had their reproductive organs assessed by transabdominal ultrasound. Ovarian findings were compared to laparoscopic findings while performing laparoscopic ovariectomy or salpingectomy. Vaginal cytology was performed and serum progesterone levels were determined. By combining all data the oestrous cycle stage of each lion was determined. One lion was far pregnant and was not operated on. In adults a uterine body could be seen ultrasonographically in 67% of lions while mural structures could be distinguished in 44% of lions. Five uterine horns could be seen in 3 lions. In 12 adults 10 ovaries were found of which eight had discernable follicles or luteal structures. During laparoscopy 12 active ovaries were seen with luteal structures seen in 11 ovaries and follicles in 2 ovaries. Using laparoscopy as the gold standard, ultrasonography had a sensitivity of 66% and specificity of 83% to detect ovarian reproductive activity. Two uterine cysts and a cluster of periovarian cysts were seen in three different lions. Three lions were pregnant, two were in oestrus, three in a luteal phase (dioestrus), and four were in anoestrus. Transabdominal ultrasound in combination with serum progesterone levels and vaginal cytology can be used to assess ovarian cyclical activity with reasonable accuracy in captive bred lions.

    Genital melanomas (GM) are the second most common cancer of the female external genitalia and may be confused with atypical genital nevi (AGN), which exhibit atypical histological features but have benign behavior. In this study, we compared the clinical, histological, and molecular features of 19 GM and 25 AGN. We described chromosomal copy number aberrations and the mutational status of 50 oncogenes and tumor suppressor genes in both groups. Our study showed that a pigmented lesion occurring in mucosal tissue, particularly in postmenopausal women, was more likely to be a melanoma than a nevus. GM had high levels of chromosomal instability, with many copy number aberrations. Furthermore, we found a completely nonoverlapping pattern of oncogenic mutations when comparing GM and AGN. In GM, we report somatic mutations in KIT and TP53. Conversely, AGN had frequent BRAF V600E mutations, which were not seen in any of the GM. Our results show that GM and AGN have distinct clinical and molecular changes and that GM have a different mutational pattern compared with AGN. Copyright © 2016 The Authors.

    Primary primitive neuroectodermal tumor (PNET) of the female genital tract is rare, and its proper classification remains unclear. The clinical, histologic, and immunophenotypic features as well as EWSR1 rearrangement status of 19 gynecologic PNETs, including 10 ovarian, 8 uterine, and 1 vulvar tumors, are herein reported. Patient age ranged from 12 to 68 years, with a median age of 20 and 51 years among those with ovarian and uterine PNETs, respectively. Morphologic features of central nervous system (CNS) tumors were seen in 15 PNETs, including 9 medulloblastomas, 3 ependymomas, 2 medulloepitheliomas, and 1 glioblastoma, consistent with central PNET. The remaining 4 PNETs were composed entirely of undifferentiated small round blue cells and were classified as Ewing sarcoma/peripheral PNET. Eight PNETs were associated with another tumor type, including 5 ovarian mature cystic teratomas, 2 endometrial low-grade endometrioid carcinomas, and a uterine carcinosarcoma. By immunohistochemistry, 17 PNETs expressed at least 1 marker of neuronal differentiation, including synaptophysin, NSE, CD56, S100, and chromogranin in 10, 8, 14, 8, and 1 tumors, respectively. GFAP was positive in 4 PNETs, all of which were of central type. Membranous CD99 and nuclear Fli-1 staining was seen in 10 and 16 tumors, respectively, and concurrent expression of both markers was seen in both central and Ewing sarcoma/peripheral PNETs. All tumors expressed vimentin, whereas keratin cocktail (CAM5.2, AE1/AE3) staining was only focally present in 4 PNETs. Fluorescence in situ hybridization was successful in all cases and confirmed EWSR1 rearrangement in 2 of 4 tumors demonstrating morphologic features of Ewing sarcoma/peripheral PNET and concurrent CD99 and Fli-1 expression. In conclusion, central and Ewing sarcoma/peripheral PNETs may be encountered in the female genital tract with central PNETs being more common. Central PNETs show a spectrum of morphologic features that overlaps with CNS

    The concept of genitourinary syndrome of menopause (GSM) was recently introduced and has been gaining widespread use. While some justifications for its introduction are straightforward, others may be questionable. Numerous unspecific symptoms and signs were included in the definition of the syndrome, but the minimum number required for diagnosis was not established. While the GSM definition is designed to facilitate identifying vulvovaginal and urinary estrogen-deprivation-associated symptoms and signs, several concerns have evolved: (1) the syndrome may result in the underdiagnosis of vulvar and urinary pathology; and (2) serious conditions (e.g., high-grade squamous intraepithelial lesions of the vulva or vulvar intraepithelial neoplasia, differentiated type) may be missed while others may not receive appropriate treatment (e.g., lichen sclerosus, overactive bladder). In addition, the transformation of urogenital symptoms and signs into a syndrome may create an iatrogenization of menopause, which, consequently, can lead to demand for (and offer of) a panacea of treatments. This can be detrimental to the care of women who require focused therapy rather than global treatment addressing a variety of genitourinary conditions, not all of which even require any form of intervention. Women's needs may be better served by having a more precise urogenital diagnosis.

    Whether unique human immunodeficiency type 1 (HIV) genotypes occur in the genital tract is important for vaccine development and management of drug resistant viruses. Multiple cross-sectional studies suggest HIV is compartmentalized within the female genital tract. We hypothesize that bursts of HIV replication and/or proliferation of infected cells captured in cross-sectional analyses drive compartmentalization but over time genital-specific viral lineages do not form; rather viruses mix between genital tract and blood. Eight women with ongoing HIV replication were studied during a period of 1.5 to 4.5 years. Multiple viral sequences were derived by single-genome amplification of the HIV C2-V5 region of env from genital secretions and blood plasma. Maximum likelihood phylogenies were evaluated for compartmentalization using 4 statistical tests. In cross-sectional analyses compartmentalization of genital from blood viruses was detected in three of eight women by all tests; this was associated with tissue specific clades containing multiple monotypic sequences. In longitudinal analysis, the tissues-specific clades did not persist to form viral lineages. Rather, across women, HIV lineages were comprised of both genital tract and blood sequences. The observation of genital-specific HIV clades only in cross-sectional analysis and an absence of genital-specific lineages in longitudinal analyses suggest a dynamic interchange of HIV variants between the female genital tract and blood.

    Galectins are an evolutionarily ancient and widely expressed family of lectins that have unique glycan-binding characteristics. They are pleiotropic regulators of key biological processes, such as cell growth, proliferation, differentiation, apoptosis, signal transduction, and pre-mRNA splicing, as well as homo- and heterotypic cell-cell and cell-extracellular matrix interactions. Galectins are also pivotal in immune responses since they regulate host-pathogen interactions, innate and adaptive immune responses, acute and chronic inflammation, and immune tolerance. Some galectins are also central to the regulation of angiogenesis, cell migration and invasion. Expression and functional data provide convincing evidence that, due to these functions, galectins play key roles in shared and unique pathways of normal embryonic and placental development as well as oncodevelopmental processes in tumorigenesis. Therefore, galectins may sometimes act as double-edged swords since they have beneficial but also harmful effects for the organism. Recent advances facilitate the use of galectins as biomarkers in obstetrical syndromes and in various malignancies, and their therapeutic applications are also under investigation. This review provides a general overview of galectins and a focused review of this lectin subfamily in the context of inflammation, infection and tumors of the female reproductive tract as well as in normal pregnancies and those complicated by the great obstetrical syndromes.

    In the female genital tract, vaginal colposcopy, endometrial mucosal integrity and inflammatory mediators are potential in vivo biomarkers of microbicide and contraceptive safety. A randomized, blinded crossover trial of 18 subjects comparing effects of nonoxynol-9 vaginal gel (Gynol II; putative inflammatory gel), hydroxyethyl cellulose gel (HEC; putative inert gel) and no gel exposure on endometrial and vaginal epithelial integrity and endometrial and vaginal inflammatory markers [interleukin (IL) 1β, IL-6, IL-8, MCP-1, MIP-1α, MIP-1β, RANTES, tumor necrosis factor α, IL-1RA, IL-10, SLPI). Gynol II was associated with more vaginal lesions. No endometrial disruptions were observed across conditions. In the vagina, RANTES (p=.055) and IL-6 (p=.04) were higher after HEC exposure than at baseline. In the endometrium, IL-1β (p=.003) and IL-8 (p=.025) were lower after Gynol II cycles than after no gel. Gynol II and HEC may modulate inflammatory markers in the vagina and endometrium. How these changes relate to infection susceptibility warrants further study. Copyright © 2011 Elsevier Inc. All rights reserved.

    At the interface of the external environment and the mucosal surface of the female reproductive tract (FRT) lies a first-line defense against pathogen invasion that includes antimicrobial peptides (AMP). Comprised of a unique class of multifunctional, amphipathic molecules, AMP employ a wide range of functions to limit microbial invasion and replication within host cells as well as independently modulate the immune system, dampen inflammation and maintain tissue homeostasis. The role of AMP in barrier defense at the level of the skin and gut has received much attention as of late. Given the far reaching implications for women's health, maternal and fetal morbidity and mortality, and sexually transmissible and polymicrobial diseases, we herein review the distribution and function of key AMP throughout the female reproductive mucosa and assess their role as an essential immunological barrier to microbial invasion throughout the reproductive cycle of a woman's lifetime. A comprehensive search in PubMed/Medline was conducted related to AMP general structure, function, signaling, expression, distribution and barrier function of AMP in the FRT, hormone regulation of AMP, the microbiome of the FRT, and AMP in relation to implantation, pregnancy, fertility, pelvic inflammatory disease, complications of pregnancy and assisted reproductive technology. AMP are amphipathic peptides that target microbes for destruction and have been conserved throughout all living organisms. In the FRT, several major classes of AMP are expressed constitutively and others are inducible at the mucosal epithelium and by immune cells. AMP expression is also under the influence of sex hormones, varying throughout the menstrual cycle, and dependent on the vaginal microbiome. AMP can prevent infection with sexually transmissible and opportunistic pathogens of the female reproductive tissues, although emerging understanding of vaginal dysbiosis suggests induction of a unique AMP profile with increased

    In this study, we planned to explore the effects of sodium bicarbonate orally (NaHCO3) treatment on female patients with lower urinary tract symptoms (LUTS) who have acidic urine pH values (<6). NaHCO3 was given orally to 33 female patients for 4 weeks at a dose of 2 × 4 g/day. Laboratory values, bladder diary, the Patient Perception of Bladder Condition Score (PPBC), Patient Perception of Intensity of Urgency Scale (PPIUS), Overactive Bladder-Validated 8-question Awareness tool (OAB-V8), Pelvic Pain and Urgency & Frequency Patient Symptom Scale tests (PUFSS), and the King's Health Questionnaire (KHQ) scores before and after treatment were compared. A significant increase was detected in urine pH values measured after treatment (5.31 ± 0.52 to 7.2 ± 0.66, p < 0.001), but not in blood pH values (7.369 ± 0.33 to 7.384 ± 0.28, p = 0.14). After treatment, a significant decrease was detected in daily frequency, nocturia, urgency, and urge incontinence prevalence (p < 0.001,p = 0.003, p < 0.001, p = 0.002, respectively) and PPBC, PPIUS, PUFSS, and OAB-V8 symptom scores (p = 0.004, p = 0.002, p < 0.001, p < 0.001, respectively). A significant decrease was detected in all KHQ subunit scores. Urine alkalinization with NaHCO3 orally in female patients with LUTS and acidic urine pH has a significant level of positive effects on symptoms and symptom scores. Our results show that this new treatment modality-which is inexpensive, easy to use, and has a low side-effect profile is effective in this chronic patient group.

    Urinary Tract Infection (UTI) is a common contagion among men and women with the incidence relatively higher among women due to their differing anatomy. An understanding of the kind of pathogens implicated in urinary tract infections as well as antibiotic susceptibility profiling may help the clinician make rationally correct empirical choice in their treatment. This study is aimed at determining the type and antibiotic susceptibility pattern of bacterial uropathogens isolated from female patients attending Chukwuemeka Odumegwu Ojukwu University Teaching Hospital (COOUTH), Awka, Nigeria. Two hundred and forty patients with clinically diagnosed UTI and who were on at least 5 days' antibiotic holiday were recruited into the study. Their demographic characteristics were captured using pre-tested questionnaire. Their clean catch mid-stream urine samples were collected using sterile universal container and sent to the Microbiology Department for processing. Within 30 minutes of samples collection, the specimens were cultured and the isolates were identified, after 24 h of incubation, using standard microbiological techniques. Antibiotic susceptibility tests were done with standard antibiotic discs using the Kirby-bauer disc diffusion method. Out of the 240 urine samples, 89.17% yielded significant bacteriuria. The pathogens implicated were Escherichia coli (28.5%), Staphylococcus aureus (28.0%), Salmonella spp (22.8%) and Pseudomonas aeruginosa (20.5%). HIV status, patients age, pregnancy status and marital status all significantly affected bacteriuria rate (p value 0.05). The pattern of microbial resistance to antibiotics suggests that ceftazidime, fosfomycin and cefoxitin may not be used as first-line agents in the empirical treatment of UTIs rather; levofloxacin, meropenem or aztreonam should be considered. Levofloxacin was significantly effective against all the isolates and may be administered empirically while waiting for the culture result (Mean % susceptibility

    This study is to retrospectively evaluate the prevalence of MYD88 and CD79B mutations and the clinicopathologic characteristics of patients with primary diffuse large B cell lymphoma (DLBCL) of the female genital tract and breast. The characteristics, treatments, and outcomes of 19 patients diagnosed with primary DLBCL of the female genital tract and breast, who had formalin-fixed and paraffin-embedded tissues obtained from diagnostic samples diagnosed between January 2004 and June 2016, were analyzed retrospectively. Nineteen female patients (7 with primary breast and 12 with primary female genital tract DLBCL) were included in this retrospective study. Eleven patients (57.9%) carried a MYD88 mutation, including 10 with MYD8 L265P and 1 with the MYD88 L265S mutation. Seven patients (36.8%) harbored a CD79B mutation, which included two cases with CD79B Y196H, two cases with CD79B Y196N, one case with CD79B Y196D, one case with CD79B Y196F, and one case with CD79B Y196X. Four cases had both MYD88 and CD79B mutations. The clinicopathologic parameters, progression-free survival (PFS), and overall survival (OS) of the MYD88 mutation-carrying group were not significantly different from those of the MYD88 wild-type group except for higher LDH levels. Six patients received cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP), while 13 patients received rituximab plus CHOP, and 13 patients received central nervous system prophylaxis. The median OS and PFS were 73 and 56 months, respectively. Patients with primary breast and primary female genital tract DLBCL have a high frequency of MYD88 and CD79B mutations. The presence of these mutations does not affect survival but may offer additional therapeutic options.

    Prune belly syndrome (PBS) is a rare congenital anomaly characterized in males by a triad of anomalous genitourinary tract, deficient development of abdominal wall muscles, and bilateral cryptorchidism. Although similar anomalies have been reported in females, by definition they do not full fill the classical triad. Urorectal septum malformation sequence (URSM) is a lethal condition characterized by presence of ambiguous genitalia, absent perineal openings (urogenital and anal), and lumbosacral abnormalities. In this original case report, the authors discuss the presentation and management of what would be analogous to a Woodhouse category 1 PBS in a female newborn associated with an overlapping presentation of URSM.

    that was much lower in the postmenopausal group (P<0.001). These studies present compelling evidence that the vaginal ecosystem responds to the presence of different vaginal microorganisms. These effects were so influential that it required us to remove subjects with BV for data interpretation of the impact of hormones. We also suggest that certain changes occurring in vaginal/cervical proteins are due to bacteria or their products. Therefore, the quantitation of vaginal mucins and lectin binding offers a new method to monitor bacteria-host interactions in the female reproductive tract. The data suggest that some of the changes in these components are the result of host processing, such as the increases in mucin content, while the microflora is responsible for the increases in glycosidases and the decreases in lectin binding. The methods should be considered a valid marker for insult to the female genital tract.

    Recently, we have described the ontogeny of histofunctional differentiation changes in the oviduct of Caiman latirostris. The expression of estrogen receptor alpha and progesterone receptor shows that the caiman oviduct could be a target of the action of xenoestrogens such as the widely environmentally present Bisphenol A (BPA), early in life. The aims of this study were: to complement oviduct characterization by establishing the ontogenetic changes in androgen receptor (AR) expression and assessing the effects of early postnatal exposure to 17-β-estradiol (E2) or BPA on the histofunctional features of the oviduct. AR was expressed in all the stages studied. The spatial pattern of AR immunostaining changed from neonatal to juvenile caimans. In the luminal epithelium, changes were at the subcellular level, from cytoplasmic to nuclear. In the subepithelium, although both cytoplasmic and nuclear AR expression was observed, changes were mainly at tissue level, from the subepithelial compartment to the outer muscular layer. The oviduct was highly sensitive to E2 and BPA at the early postnatal developmental stage. E2- and BPA-exposed caimans showed increased luminal epithelial height and higher proliferative activity. Changes in histomorphological features (measured by a scoring system), steroid hormone receptors, collagen remodeling and muscle-associated proteins suggest a precocious oviduct histofunctional differentiation in E2- and BPA-exposed caimans. The modification of the temporal pattern of oviductal biomarkers suggests that organizational changes could impair C. latirostris reproductive health later in life. The alterations in the caiman female reproductive tract exposed to BPA highlight the importance of preserving aquatic environments from plastic pollution. Copyright © 2017 Elsevier Inc.

  18. Lactobacillus crispatus dominant vaginal microbiome is associated with inhibitory activity of female genital tract secretions against Escherichia coli.

    Full Text Available Female genital tract secretions inhibit E. coli ex vivo and the activity may prevent colonization and provide a biomarker of a healthy microbiome. We hypothesized that high E. coli inhibitory activity would be associated with a Lactobacillus crispatus and/or jensenii dominant microbiome and differ from that of women with low inhibitory activity.Vaginal swab cell pellets from 20 samples previously obtained in a cross-sectional study of near-term pregnant and non-pregnant healthy women were selected based on having high (>90% inhibition or low (<20% inhibition anti-E. coli activity. The V6 region of the 16S ribosomal RNA gene was amplified and sequenced using the Illumina HiSeq 2000 platform. Filtered culture supernatants from Lactobacillus crispatus, Lactobacillus iners, and Gardnerella vaginalis were also assayed for E. coli inhibitory activity.Sixteen samples (10 with high and 6 with low activity yielded evaluable microbiome data. There was no difference in the predominant microbiome species in pregnant compared to non-pregnant women (n = 8 each. However, there were significant differences between women with high compared to low E. coli inhibitory activity. High activity was associated with a predominance of L. crispatus (p<0.007 and culture supernatants from L. crispatus exhibited greater E. coli inhibitory activity compared to supernatants obtained from L. iners or G. vaginalis. Notably, the E. coli inhibitory activity varied among different strains of L. crispatus.Microbiome communities with abundant L. crispatus likely contribute to the E. coli inhibitory activity of vaginal secretions and efforts to promote this environment may prevent E. coli colonization and related sequelae including preterm birth.

    Compartmentalization of HIV-1 between the genital tract and blood was noted in half of 57 women included in 12 studies primarily using cell-free virus. To further understand differences between genital tract and blood viruses of women with chronic HIV-1 infection cell-free and cell-associated virus populations were sequenced from these tissues, reasoning that integrated viral DNA includes variants archived from earlier in infection, and provides a greater array of genotypes for comparisons. Multiple sequences from single-genome-amplification of HIV-1 RNA and DNA from the genital tract and blood of each woman were compared in a cross-sectional study. Maximum likelihood phylogenies were evaluated for evidence of compartmentalization using four statistical tests. Genital tract and blood HIV-1 appears compartmentalized in 7/13 women by >/=2 statistical analyses. These subjects' phylograms were characterized by low diversity genital-specific viral clades interspersed between clades containing both genital and blood sequences. Many of the genital-specific clades contained monotypic HIV-1 sequences. In 2/7 women, HIV-1 populations were significantly compartmentalized across all four statistical tests; both had low diversity genital tract-only clades. Collapsing monotypic variants into a single sequence diminished the prevalence and extent of compartmentalization. Viral sequences did not demonstrate tissue-specific signature amino acid residues, differential immune selection, or co-receptor usage. In women with chronic HIV-1 infection multiple identical sequences suggest proliferation of HIV-1-infected cells, and low diversity tissue-specific phylogenetic clades are consistent with bursts of viral replication. These monotypic and tissue-specific viruses provide statistical support for compartmentalization of HIV-1 between the female genital tract and blood. However, the intermingling of these clades with clades comprised of both genital and blood sequences and the absence

    Background Trichomonas vaginalis (T. vaginalis) belongs to a common sexually transmitted disease pathogen causing genitourinary trichomoniasis in both sexes. We investigated the pathogenetic mechanism of genitourinary trichomoniasis.Methods Cultured T. vaginalis bodies were injected into the vaginas of rats, or incubated with genitourinary epithelial cells of female subjects, male subjects, and sperm. The ultrastructural and microscopic changes were observed via transmission and scanning electron microscopy and through microscopic histochemistry.Results Groups of T.vaginalis adhered to PAS positive columnar cells at the surface of stratified epithelium in the middle and upper portions of the vaginas. They also traversed under these cells. The parasites were shown to be PAS, cathepsin D, and actin positive, and they could release hydrolase into the cytoplasm of adhered epithelial cells. In the amebiform T.vaginalis, microfilaments were arranged into reticular formation. Similar phenomena were found during the interaction of T.vaginalis with host cells, both in vitro and in vivo. Usually several protozoa adhered to an epithelial cell and formed polymorphic pseudopodia or surface invaginations to surround and phagocytize the microvilli or other parts of the epithelial cytoplasm. Adhesion and phagocytosis of sperm by the protozoa occurred at 15-30 minutes of incubation. Digestion of sperm was found at 45-75 minutes and was complete at 90-105 minutes.Conclusions T.vaginalis tends to parasitize at the fornix of the vagina, because this is the site where columnar cells are rich in mucinogen granules and their microvilli are helpful for adhesion and nibbling. T.vaginalis possesses some invading and attacking abilities. Shape change, canalization, encystation, phagocytosis, digestion, the cell coat, cytoskeleton, and lysosome all play important roles in the process of adhesion. They have two methods of phagocytosis: nibbling and ingestion. Genitourinary epithelium may be

    Genitourinary medical events have shown to be an issue for both short duration and long duration spaceflight, and are anticipated to also be a potential issue for future exploration missions as well. This is based on actual historical pre-, in- and post-flight medical events, as well as assessment of what future flight challenges lay ahead. For this study, retrospective record review, as well as prospective studies of ultrasound and contingency management procedure development, and oral urinary stone prophylaxis were conducted. Results showed that the incidence of prior urinary calculi in- and post-flight was a risk driver for development of on-orbit countermeasures, as well as diagnostic and therapeutic methods for a possible in-flight calculus contingency. Oral potassium citrate and bisphosphonate preparations show promise for prophylaxis in spaceflight risk reduction. We conclude that a properly developed approach of selection, monitoring, and preventive medicine with effective countermeasures, along with early imaging diagnosis and minimally-invasive contingency intervention, should prevent issues such as urinary calculi from having a significant mission impact for exploration-class spaceflight.

    The lower reproductive tract of nonhuman primates is colonized with a diverse microbiota, resembling bacterial vaginosis (BV), a gynecological condition associated with negative reproductive outcomes in women. Our 4 aims were to: (i) assess the prevalence of low Lactobacilli and a BV-like profile in female rhesus monkeys; (ii) quantify cytokines in their cervicovaginal fluid (CVF); (iii) examine the composition and structure of their mucosal microbiota with culture-independent sequencing methods; and (iv) evaluate the potential influence on reproductive success. CVF specimens were obtained from 27 female rhesus monkeys for Gram's staining, and to determine acidity (pH), and quantify proinflammatory cytokines. Based on Nugent's classification, 40% had a score of 7 or higher, which would be indicative of BV in women. Nugent scores were significantly correlated with the pH of the CVF. Interleukin-1ß was present at high concentrations, but not further elevated by high Nugent scores. Vaginal swabs were obtained from eight additional females to determine microbial diversity by rRNA gene amplicon sequencing. At the phylum level, the Firmicutes/Bacteroidetes ratio was low. The relative abundance of Lactobacilli was also low (between 3% and 17%), and 11 other genera were present at >1%. However, neither the microbial diversity in the community structure, nor high Nugent scores, was associated with reduced fecundity. Female monkeys provide an opportunity to understand how reproductive success can be sustained in the presence of a diverse polymicrobial community in the reproductive tract. © 2017 Wiley Periodicals, Inc.

    Schistosoma (S.) haematobium is a neglected tropical disease which may affect any part of the genital tract in women. Female genital schistosomiasis (FGS) may cause abnormal vaginal discharge, contact bleeding, genital tumours, ectopic pregnancies and increased susceptibility to HIV. Symptoms may mimic those typical of sexually transmitted infections (STIs) and women with genital schistosomiasis may be incorrectly diagnosed. An expert consensus meeting suggested that the following findings by visual inspection should serve as proxy indicators for the diagnosis of schistosomiasis of the lower genital tract in women from S. haematobium endemic areas: sandy patches appearing as (1) single or clustered grains or (2) sandy patches appearing as homogenous, yellow areas, or (3) rubbery papules. In this atlas we aim to provide an overview of the genital mucosal manifestations of schistosomiasis in women. Photocolposcopic images were captured from women, between 1994 and 2012 in four different study sites endemic for S. haematobium in Malawi, Zimbabwe, South Africa and Madagascar. Images and specimens were sampled from sexually active women between 15 and 49 years of age. Colposcopic images of other diseases are included for differential diagnostic purposes. This is the first atlas to present the clinical manifestations of schistosomiasis in the lower female genital tract. It will be freely available for online use, downloadable as a presentation and for print. It could be used for training purposes, further research, and in clinical practice.

    Ram sperma, which had been sucessfully labelled with Na 131 I was followed up by means of a gamma camera up to 150 minutes from insemination while migrating through the genital tract of female sheep. The study had been undertaken primarily for the purpose of testing the method and the suitability of this radionuclide for sperm labelling without major impairment of spermatic motility. Also included in the study were comparisons between oestrus induction by means of fluorogestonacetate vaginal sponges plus pregnant mare serum gonadotrophin treatment and spontaneous oestrus or between fresh and liquid-preserved ram sperma for migration capacity as well as observation of passive migration of sperma in the genital tract of sheep. Rompun anesthesia was applied to sheep for sedation for gamma camera observation. (author)

    Full Text Available Sexually transmitted infections represent major health problem in females all over the world if remained undiagnosed and untreated. They can have adverse influence on reproduction and health of a mother and a newborn. The development of molecular methods has permitted the detection of an array of microbes whose pathologic roles in urogenital infections need to be further studied. Ureaplasmas (Ureaplasma spp., being originally found in 1954 from male urogenital tract, are prokaryotic cells without a cell wall, ranging from 0.1 to 1 μm in length. Fourteen known Ureaplasma serovars have been divided in two species based on their phenotypic and genotypic features, Ureaplasma parvum and Ureaplasma urealyticum detected and identified separately using polymerase chain reaction assays. Both are generally considered as genital tract commensals. U. urealyticum is most probably associated with male urethritis which has not been found for U. parvum. Recent studies with supposedly healthy women reported their detection rate between 18-87 % for U. parvum and 6-10 % for U. urealyticum. Even though they have been found to be associated with chorioamnionitis, preterm birth and perinatal complications more commonly then other commensals in this region the rising question regarding their pathogenic role in females remains unsolved and the guidelines regarding the diagnostic screening and treatment are inconsistent. The aim of our paper is to review the microbiological characteristics, diagnostic methods and epidemiology of newly differentiated U. parvum and U. urealyticum, and to assess evidence speaking pro and contra their clinical role in causing lower urogenital tract infection in women. Since both bacteria are susceptible to antimicrobials it is of utmost importance for clinicians to decide whether or not to search for one or both of them routinely and treat accordingly in order to prevent ascending upper genital tract infection as well as complications in

  7. The female lower genital tract is a privileged compartment with IL-10 producing dendritic cells and poor Th1 immunity following Chlamydia trachomatis infection.

    Full Text Available While a primary genital tract infection with C. trachomatis stimulates partial-protection against re-infection, it may also result in severe inflammation and tissue destruction. Here we have dissected whether functional compartments exist in the genital tract that restrict Th1-mediated protective immunity. Apart from the Th1-subset, little is known about the role of other CD4(+ T cell subsets in response to a genital tract chlamydial infection. Therefore, we investigated CD4(+ T cell subset differentiation in the genital tract using RT-PCR for expression of critical transcription factors and cytokines in the upper (UGT and lower genital tract (LGT of female C57BL/6 mice in response to C. trachomatis serovar D infection. We found that the Th1 subset dominated the UGT, as IFN-γ and T-bet mRNA expression were high, while GATA-3 was low following genital infection with C. trachomatis serovar D. By contrast, IL-10 and GATA-3 mRNA dominated the LGT, suggesting the presence of Th2 cells. These functional compartments also attracted regulatory T cells (Tregs differently as increased FoxP3 mRNA expression was seen primarily in the UGT. Although IL-17A mRNA was somewhat up-regulated in the LGT, no significant change in RORγ-t mRNA expression was observed, suggesting no involvement of Th17 cells. The dichotomy between the LGT and UGT was maintained during infection by IL-10 because in IL-10-deficient mice the distinction between the two compartments was completely lost and a dramatic shift to the predominance of Th1 cells in the LGT occurred. Unexpectedly, the major source of IL-10 was CD11c(+ CD11b(+ DC, probably creating an anti-inflammatory privileged site in the LGT.

    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.

    Despite advances in ART, implantation and pregnancy rates per embryo transfer still remain low. IVF laboratories strive to ensure that the process of handling gametes in vitro closely mimics the in vivo environment. However, there remains a lack of knowledge regarding the in vivo regulation and dynamic variation in biophysical parameters such as oxygen concentration, pH and temperature within the reproductive tract. To undertake a systematic review of the current understanding of the physico-chemical parameters of oxygen tension (pO2), pH and temperature within the female reproductive tract, and their potential implications in clinical and pathological processes related to fertility and those pertaining to limited reproductive capacity. A comprehensive literature search was performed using electronic databases including Medline, Embase, Cochrane Library and Pubmed to identify original and review articles addressing the biophysical parameters (pO2, pH and temperature) in the female reproductive tract of any species. The search included all studies published between 1946 and November 2015. Search terms included 'oxygen', 'pH', 'hydrogen ion concentration', 'acid base' and others terms. We also used special features and truncations to identify synonyms and broaden the search. Studies were excluded if they only assessed embryo culture conditions, fetal acid-base status, oxidative stress, outcomes of pregnancy and measurements of these parameters in non-reproductive organs. Our search generated 18 685 records and 60 articles were included. pO2 within the female reproductive tract shows cyclical variation and minute-to-minute oscillations, which may be influenced by uterine contractility, hormones, the autonomic system, cardiac pulsatility, and myometrial and smooth muscle integrity. Fine balanced control of pO2 and avoidance of overwhelming oxidative stress is crucial for embryogenesis and implantation. The pH in the female reproductive tract is graduated, with lowest p

    The female reproductive tract (FRT) is one of the major mucosal invasion sites for HIV-1. This site has been neglected in previous HIV-1 vaccine studies. Immune responses in the FRT after systemic vaccination remain to be characterized. Using a modified vaccinia virus Ankara (MVA) as a vaccine model, we characterized specific immune responses in all compartments of the FRT of nonhuman primates after systemic vaccination. Memory T cells were preferentially found in the lower tract (vagina and cervix), whereas APCs and innate lymphoid cells were mainly located in the upper tract (uterus and fallopian tubes). This compartmentalization of immune cells in the FRT was supported by transcriptomic analyses and a correlation network. Polyfunctional MVA-specific CD8 + T cells were detected in the blood, lymph nodes, vagina, cervix, uterus, and fallopian tubes. Anti-MVA IgG and IgA were detected in cervicovaginal fluid after a second vaccine dose. Thus, systemic vaccination with an MVA vector elicits cellular and Ab responses in the FRT.

    To review the topic of urinary tract infections (UTI) during pregnancy and menopause. UTI during pregnancy and menopause have great relevance in the field of urologic infections; during pregnancy because of the particularities involved in its diagnosis and treatment and potential consequences to the fetus and mother; menopausal UTI because this group of women is numerous and represents a growing section of the general population pyramid, due to the aging of population in developed countries associated with longer life expectancies and grater demand for quality of life. We performed a bibliographic review combined with our personal experience. During pregnancy there are several functional and anatomical changes that condition not only a higher risk of UTI, but also an additional treatment difficulty due to antimicrobial pharmacokinetics alterations and potential damage to the fetus. Despite efforts to find an easy, fast and reliable test for bacteriuria detection, urine culture continues to be the first diagnostic test for its detection and follow up during pregnancy. Penicillin derivates and cephalosporins continue to be the first choice because their lack of adverse effects on either fetus or mother. Alternative options like phosphomicin and aztreonam although they show low toxicity there is need for more studies supporting their suitability for the treatment of pregnancy UTIs. Menopausal female UTI have their different features from those in younger women. Hormonal alterations derived from gonadal atrophy associate functional changes in the vaginal ecosystem, making it prone to enterobacteriaceae colonization as a first step up to the urinary tract. This associated with genitourinary tract anatomical alterations inherent t aging make UTI extraordinary prevalent in this growing segment of population. Treatment lines focus on hormonal alteration correction and proper antimicrobial prophylaxis and vaccines in a close future. UTIs during pregnancy and menopause have

    Topical microbicides are a leading strategy for prevention of HIV mucosal infection to women; however, numerous pharmacokinetic limitations associated with coitally related dosing strategy have contributed to their limited success. Here we test the hypothesis that adeno-associated virus (AAV) mediated delivery of the b12 human anti-HIV-1 gp120 minibody gene to the lower genital tract of female rhesus macaques (Rh) can provide prolonged expression of b12 minibodies in the cervical-vaginal secretions. Gene transfer studies demonstrated that, of various green fluorescent protein (GFP)-expressing AAV serotypes, AAV-6 most efficiently transduced freshly immortalized and primary genital epithelial cells (PGECs) of female Rh in vitro. In addition, AAV-6-b12 minibody transduction of Rh PGECs led to inhibition of SHIV162p4 transmigration and virus infectivity in vitro. AAV-6-GFP could also successfully transduce vaginal epithelial cells of Rh when applied intravaginally, including p63+ epithelial stem cells. Moreover, intravaginal application of AAV-6-b12 to female Rh resulted in prolonged minibody detection in their vaginal secretions throughout the 79-day study period. These data provide proof of principle that AAV-6-mediated delivery of anti-HIV broadly neutralizing antibody (BnAb) genes to the lower genital tract of female Rh results in persistent minibody detection for several months. This strategy offers promise that an anti-HIV-1 genetic microbicide strategy may be possible in which topical application of AAV vector, with periodic reapplication as needed, may provide sustained local BnAb expression and protection.

    Traditional surgery presents some disadvantages, such as the necessity for general anesthesia, hemorrhage, recurrence of pathology, and the possible onset of dyspareunia due to an excessive scarring. CO2 laser surgery might resolve these problems and might be employed in a wider range of clinical indications than usual. We examined the results of CO2 laser surgery in patients affected by benign pathologies and congenital malformations of the female lower genital tract. In this observational study, we enrolled 49 women who underwent CO2 laser surgery for the following indications: Bartholin's gland cyst, imperforate hymen, vaginal septum, Nabothian cyst, and vaginal polyps. Feasibility, cost-effectiveness, complication rate, recurrence rate, short- and long-term outcomes were assessed. All procedures were carried out in a short operative time, without any intraoperative complications. Only 1 (2.0%) out of 49 patients required a hemostatic suture for bleeding. Postoperative period was uneventful in all patients, except 6 (12.2%) out of 49 patients who reported pain one day after surgery, successfully treated with paracetamol. Healing was rapid and excellent in all cases; no wound infection, scarring or stenosis were noticed. Preoperative symptoms reduced or disappeared in all cases. No recurrence was observed and no re-intervention was needed. CO2 laser surgery provides several advantages over traditional surgery, as its systematic use in treating pre-invasive, benign, and congenital pathologies of the female lower genital tract reduces patient discomfort, improves short- and long-term outcomes, and optimizes cost-effectiveness.

    The growth factor progranulin has emerged in recent years as a critical regulator of transformation in several cancer models, including breast cancer, glioblastomas, leukemias, and hepatocellular carcinomas. Several laboratories, including ours, have also demonstrated an important role of progranulin in several genitourinary cancers, including ovarian, endometrial, cervical, prostate, and bladder tumors, where progranulin acts as an autocrine growth factor thereby modulating motility and invasion of transformed cells. In this review, we will focus on the mechanisms of action and regulation of progranulin signaling in genitourinary cancers with a special emphasis on prostate and bladder tumors.

    Full Text Available Intravaginal anti-HIV microbicides could provide women with a self-controlled means for HIV prevention, but results from clinical trials have been largely disappointing. We postulated that unrecognized effects of intravaginal gels on the upper female reproductive tract might contribute to the lower-than-expected efficacy of HIV microbicides. Our objective was to study the effects of intravaginal gels on the immune microenvironment of the cervix and uterus. In this randomized crossover study, 27 healthy female volunteers used a nightly application of intravaginal nonoxynol-9 (N9 gel as a "failed" microbicide or the universal placebo gel (UPG as a "safe" gel (intervention cycles, or nothing (control cycle from the end of menses to the mid-luteal phase. At a specific time-point following ovulation, all participants underwent sample collection for measurements of T-cell phenotypes, gene expression, and cytokine/chemokine protein concentrations from 3 anatomic sites above the vagina: the cervical transformation zone, the endocervix and the endometrium. We used hierarchical statistical models to estimate mean (95% CI intervention effects, for N9 and UPG relative to control. Exposure to N9 gel and UPG generated a common "harm signal" that included transcriptional up-regulation of inflammatory genes chemokine (C-C motif ligand 20 (macrophage inflammatory factor-3alpha and interleukin 8 in the cervix, decreased protein concentrations of secretory leukocyte protease inhibitor, and transcriptional up-regulation of inflammatory mediators glycodelin-A and osteopontin in the endometrium. These results need to be replicated with a larger sample, but underscore the need to consider the effects of microbicide agents and gel excipients on the upper female reproductive tract in studies of vaginal microbicides.

    It is well established that interferon gamma (IFN-γ) production by CD4 + T cells is critical for antiviral immunity against herpes simplex virus 2 (HSV-2) genital infection. However, the role of interleukin-17A (IL-17A) production by CD4 + T cells in HSV-2 antiviral immunity is yet to be elucidated. Here we demonstrate that IL-17A plays an important role in enhancing antiviral T helper type 1 (T h 1) responses in the female genital tract (FGT) and is essential for effective protection conferred by HSV-2 vaccination. While IL-17A did not play a critical role during primary genital HSV-2 infection, seen by lack of differences in susceptibility between IL-17A-deficient ( IL-17A -/- ) and wild-type (WT) C57BL/6 mice, it was critical for mediating antiviral responses after challenge/reexposure. Compared to WT mice, IL-17A -/- mice (i) infected intravaginally and reexposed or (ii) vaccinated intranasally and challenged intravaginally demonstrated poor outcomes. Following intravaginal HSV-2 reexposure or challenge, vaccinated IL-17A -/- mice had significantly higher mortality, greater disease severity, higher viral shedding, and higher levels of proinflammatory cytokines and chemokines in vaginal secretions. Furthermore, IL-17A -/- mice had impaired T h 1 cell responses after challenge/reexposure, with significantly lower proportions of vaginal IFN-γ + CD4 + T cells. The impaired T h 1 cell responses in IL-17A -/- mice coincided with smaller populations of IFN-γ + CD4 + tissue resident memory T (T RM ) cells in the genital tract postimmunization. Taken together, these findings describe a novel role for IL-17A in regulating antiviral IFN-γ + T h 1 cell immunity in the vaginal tract. This strategy could be exploited to enhance antiviral immunity following HSV-2 vaccination. IMPORTANCE T helper type 1 (T h 1) immunity, specifically interferon gamma (IFN-γ) production by CD4 + T cells, is critical for protection against genital herpesvirus (HSV-2) infection, and

    The local tolerance of the antiretroviral spermicide, WHI-07 (5-bromo-6-methoxy-5,6-dihydro-3'-azidothymidine-5'-(p-bromophenyl)-methoxyalaninyl phosphate)-loaded gel-microemulsion was evaluated in a physiologically relevant and sensitive porcine model. Gilts (Duroc) in nonestrus stages of the reproductive cycle received either a single or a daily intravaginal application of 2.0% WHI-07 via a gel-microemulsion for 6 days. Cervicovaginal lavage (CVL) fluid was obtained for up to 72 h after a single exposure and the cellular profile and levels of inflammatory cytokines (IL-1beta, IL-8, IFN-gamma and TNF-alpha) were quantitated by flow cytometry and chemiluminescence-based multiplex immunoassay, respectively. The reproductive tract (vagina, cervix, uteri and Fallopian tubes) harvested on day 7 was scored histologically for evidence of mucosal irritation using a new scoring criterion for ten histological endpoints that reflect pathological changes in the epithelial/ subepithelial and vascular/perivascular compartments. When compared with irritant reactions caused by the detergent-type spermicide, benzalkonium chloride (BZK), the scatter profile of CVL immune cells and basal levels of proinflammatory cytokines (IL-1beta, IL-8, IFN-gamma and TNF-alpha) in CVL fluid were unaffected by intravaginal exposure to 2% WHI-07. Unlike BZK, endpoint histology of the proximal and distal regions of the reproductive tract from gilts treated with 2.0% WHI-07 via gel-microemulsion for 6 days did not result in mucosal irritation or alteration in the epithelium, subepithelium/lamina propria, vessels/perivascular tissues and underlying/surrounding muscles. Based on surrogate markers for inflammation, leukocyte profile and histologic data for local tolerance, repeated intravaginal administration of WHI-07 via gel-microemulsion as a prophylactic contraceptive is unlikely to cause vaginal irritation.

    Full Text Available Human Immunodeficiency Virus-type 1 (HIV- 1 binds to CD4 and CCR5 receptors on target cells in the human female reproductive tract. We sought to determine whether reducing levels of messenger RNA (mRNA transcripts that encode these receptors in female reproductive tract cells could protect mucosal tissue explants from HIV- 1 infection. Explants prepared from the endometrium, endocervix, and ectocervix of hysterectomy tissues from HIV-1 sero-negative women were exposed to nanoparticles containing CD4- and CCR5-specific short-interfering RNA (siRNA sequences. Explants were then exposed two days later to HIV-1, and HIV-1 reverse transcripts were measured five days post-infection. Explants treated with nanoparticles containing CD4- and CCR5-specific siRNA showed reduced levels of CD4 and CCR5 transcripts, and significantly lower levels of HIV-1 reverse transcripts compared to those treated with an irrelevant siRNA. In female reproductive tract explants and in peripheral blood cell cultures, siRNA transfection induced the secretion of IFN-alpha (IFN-α, a potent antiviral cytokine. In female mice, murine-specific Cd4-siRNA nanoparticles instilled within the uterus significantly reduced murine Cd4 transcripts by day 3. Our findings demonstrate that siRNA nanoparticles reduce expression of HIV-1 infectivity receptors in human female reproductive tract tissues and also inhibit HIV-1 infection. Murine studies demonstrate that nanoparticles can penetrate the reproductive tract tissues in vivo and silence gene expression. The induction of IFN-α after siRNA transfection can potentially contribute to the antiviral effect. These findings support the therapeutic development of nanoparticles to deliver siRNA molecules to silence host cell receptors in the female reproductive tract as a novel microbicide to inhibit mucosal HIV-1 transmission.

    Full Text Available Abstract Background Rural-to-urban migration involves a high proportion of females because job opportunities for female migrants have increased in urban industrial areas. Those who migrate may be healthier than those staying in the village and they may benefit from better health care services at destination, but the 'healthy' effect can be reversed at destination due to migration-related health risk factors. The study aimed to explore the need for health care services for reproductive tract infections (RTIs among female migrants working in the Sai Dong industrial zone as well as their services utilization. Methods The cross sectional study employed a mixed method approach. A cohort of 300 female migrants was interviewed to collect quantitative data. Two focus groups and 20 in-depth interviews were conducted to collect qualitative data. We have used frequency and cross-tabulation techniques to analyze the quantitative data and the qualitative data was used to triangulate and to provide more in-depth information. Results The needs for health care services for RTI were high as 25% of participants had RTI syndromes. Only 21.6% of female migrants having RTI syndromes ever seek helps for health care services. Barriers preventing migrants to access services were traditional values, long working hours, lack of information, and high cost of services. Employers had limited interests in reproductive health of female migrants, and there was ineffective collaboration between the local health system and enterprises. These barriers were partly caused by lack of health promotion programs suitable for migrants. Most respondents needed more information on RTIs and preferred to receive these from their employers since they commonly work shifts - and spend most of their day time at work. Conclusion While RTIs are a common health problem among female migrant workers in industrial zones, female migrants had many obstacles in accessing RTI care services. The findings

    Full Text Available Currently, there are mounting data suggesting that HIV-1 acquisition in women can be affected by the use of certain hormonal contraceptives. However, in non-human primate models, endogenous or exogenous progestin-dominant states are shown to increase acquisition. To gain mechanistic insights into this increased acquisition, we studied how mucosal barrier function and CD4+ T-cell and CD68+ macrophage density and localization changed in the presence of natural progestins or after injection with high-dose DMPA. The presence of natural or injected progestins increased virus penetration of the columnar epithelium and the infiltration of susceptible cells into a thinned squamous epithelium of the vaginal vault, increasing the likelihood of potential virus interactions with target cells. These data suggest that increasing either endogenous or exogenous progestin can alter female reproductive tract barrier properties and provide plausible mechanisms for increased HIV-1 acquisition risk in the presence of increased progestin levels.

    While the prevalence of Human immunodeficiency virus-1 (HIV-1) infection has stabilized globally, it continues to be the leading cause of death among women of reproductive age. The majority of new infections are transmitted heterosexually, and women have consistently been found to be more susceptible to HIV-1 infection during heterosexual intercourse compared to men. This emphasizes the need for a deeper understanding of how the microenvironment in the female genital tract (FGT) could influence HIV-1 acquisition. This short review focuses on our current understanding of the interplay between estrogen, progesterone, and the cervicovaginal microbiome and their immunomodulatory effects on the FGT. The role of hormonal contraceptives and bacterial vaginosis on tissue inflammation, T cell immunity and HIV-1 susceptibility is discussed. Taken together, this review provides valuable information for the future development of multi-purpose interventions to prevent HIV-1 infection in women.

    Aim The main goal of this investigation was to evaluate the influence of positive Staphylococcus aureus culture from the genital tract on patients receiving radiation therapy, suffering from carcinoma of the uterus. The other aim was to observe radiation therapy complications. Background Radiation therapy of patients suffering from cervical cancer can be connected with inflammation of the genitourinary tract. Materials and methods In years 2006–2010 vaginal swabs from 452 patients were examined. 39 women with positive S. aureus cultures were analysed. Results Complications and interruptions during radiation therapy were observed in 7 (18.9%) of 37 patients with positive vaginal S. aureus culture. One of them, a 46-year-old woman developed pelvic inflammatory disease. None of the six patients who received palliative radiotherapy showed interruption in this treatment. Isolated S. aureus strains were classified into 13 sensitivity patterns, of which 8 were represented by 1 strain, two by 2 strains and three by 13, 8 and 6 strains. One strain was diagnosed as methicillin resistant S. aureus (MRSA). Conclusions The results of the present study show that S. aureus may generally be isolated from the genital tract of female patients with neoplastic disease of uterus but is not often observed as inflammation factor of this tract. Comparison of species’ resistance patterns may be used in epidemiological studies in order to discover the source of infections and therefore be of profound significance in the prevention of nosocomial infections.

    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.

    Alveolar soft part sarcoma (ASPS) is a morphologically distinctive neoplasm of unknown differentiation that bears a characteristic gene fusion involving ASPSCR1 and TFE3. ASPS can occur in the female genital tract, but is rare. Eleven cases with an initial diagnosis of ASPS at female genital tract sites were evaluated for their morphologic features and immunoprofile using a panel of antibodies (TFE3, HMB45, melan-A, smooth muscle actin, desmin, and h-Caldesmon). In addition, the presence of TFE3 rearrangement and subsequent ASPSCR1-TFE3 fusion were determined by fluorescence in situ hybridization. Ten tumors retained their classification as ASPS based on their morphologic appearance, immunohistochemical profile, and demonstration of ASPSCR1-TFE3 fusion. The remaining case was reclassified as conventional-type PEComa due to its pattern of HMB45, melan-A, and desmin positivity as well as absence of TFE3 rearrangement. Sites of the 10 ASPS were uterine corpus (3), cervix (2), uterus not further specified (2), vagina (2), and vulva (1). The age of the patients ranged from 15 to 68 years (mean 34 y, median 32 y). The tumors demonstrated a spectrum of morphologic features, but all had a consistent immunophenotype of strong TFE3 nuclear expression and lack of muscle (smooth muscle actin, desmin, h-Caldesmon) and melanocytic (melan-A, HMB45) markers, except focal positivity for HMB45 in 1. Follow-up was available for 4 patients ranging from 1 to 35 months (mean 15 mo, median 25 mo) and they were alive and had no evidence of recurrence or metastasis at last follow-up. Distinguishing ASPS from its morphologic mimics, particularly PEComa, is important due to increasingly efficacious targeted agents such as MET-selective and VEGF signaling inhibitors in the former and mTOR inhibition therapy in the latter.

    Tumour markers CA-50 and CA-242 were measured by immunometric assay (IRMA) to investigate their usefulness in the diagnosis of cancer of the pancreas, biliary tract, liver, breast, lung, gastrointestinal and genitourinary systems. The cutoff points, derived from studies on normal subjects and those with proven benign disease, were 20 u/ml and 12 u/ml for CA-50 and CA-242 respectively. Both markers were found to be generally useful with significant differences between malignant and non malignant disease. The highest positive rates, were found in cancers of the pancreas and gall bladder. The overall rate of false positives was low. It is concluded that measurements of CA-50 and CA-242 are useful in the detection of malignancy, particularly of the pancreas and biliary tract. 2 figs, 2 tabs

    Vitellogenin (Vg) and lipophorin (Lp) are lipoproteins which play important roles in female reproductive physiology of insects. Both are actively taken up by growing oocytes and especially Vg and its receptor are considered as female-specifically expressed. The finding that the fat body of in honey bee (Apis mellifera) drones synthesizes Vg and is present in hemolymph has long been viewed as a curiosity. The recent paradigm change concerning the role played by Vg in honey bee life history, especially social division of labor, has now led us to investigate whether a physiological constellation similar to that seen in female reproduction may also be represented in the male sex. By means of Western blot analysis we could show that both Vg and Lp are present in the reproductive tract of adult drones, including the accessory (mucus) glands, but apparently are not secreted. Furthermore, we analyzed the transcript levels of the genes encoding these proteins (vg and lp), as well as their putative receptors (Amvgr and Amlpr) in fat body and accessory glands. Whereas lp, vg and Amlpr transcript levels decreased with age in both tissues, Amvgr mRNA levels increased with age in fat body. To our knowledge this is the first report that vitellogenin and its receptor are co-expressed in the reproductive system of a male insect. We interpret these findings as a cross-sexual transfer of a social physiological trait, associated with the rewiring of the juvenile hormone/vitellogenin circuitry that occurred in the female sex of honey bees.

An exploratory laparotomy revealed a cyst adhering to the cervix and a unilateral renal agenesis. Histopathology and immunohistochemical analysis of the cyst was consistent with remnants of the Wolffian duct or a Gartner duct cyst. This is a rare case of a canine Gartner duct cyst with renal agenesis and uterine anomaly. We discuss the similarity of this case to that of humans and introduce a classification in the literature for these complex urogenital malformations for further clinical research into the precise diagnosis and appropriate surgical planning.

    The 2011 American Academy of Pediatrics guidelines state that renal and bladder ultrasound (RBUS) should be performed after initial febrile urinary tract infection (UTI) in a young child, with voiding cystourethrogram (VCUG) performed only if RBUS shows abnormalities. We sought to determine test characteristics and predictive values of RBUS for VCUG findings in this setting. We analyzed 3995 clinical encounters from January 1, 2006 to December 31, 2010 during which VCUG and RBUS were performed for history of UTI. Patients who had previous postnatal genitourinary imaging or history of prenatal hydronephrosis were excluded. Sensitivity, specificity, and predictive values of RBUS for VCUG abnormalities were determined. We identified 2259 patients age UTI as the indication for imaging. RBUS was reported as "normal" in 75%. On VCUG, any vesicoureteral reflux (VUR) was identified in 41.7%, VUR grade >II in 20.9%, and VUR grade >III in 2.8%. Sensitivity of RBUS for any abnormal findings on VCUG ranged from 5% (specificity: 97%) to 28% (specificity: 77%). Sensitivity for VUR grade >III ranged from 18% (specificity: 97%) to 55% (specificity: 77%). Among the 1203 children aged 2 to 24 months imaged after a first febrile UTI, positive predictive value of RBUS was 37% to 47% for VUR grade >II (13% to 24% for VUR grade >III); negative predictive value was 72% to 74% for VUR grade >II (95% to 96% for VUR grade >III). RBUS is a poor screening test for genitourinary abnormalities. RBUS and VCUG should be considered complementary as they provide important, but different, information.

    In 2012, the Board of Directors of the International Society for the Study of Women's Sexual Health (ISSWSH) and the Board of Trustees of The North American Menopause Society (NAMS) acknowledged the need to review current terminology associated with genitourinary tract symptoms related to menopause. The 2 societies cosponsored a terminology consensus conference, which was held in May 2013. Members of the consensus conference agreed that the term genitourinary syndrome of menopause (GSM) is a medically more accurate, all-encompassing, and publicly acceptable term than vulvovaginal atrophy. GSM is defined as a collection of symptoms and signs associated with a decrease in estrogen and other sex steroids involving changes to the labia majora/minora, clitoris, vestibule/introitus, vagina, urethra and bladder. The syndrome may include but is not limited to genital symptoms of dryness, burning, and irritation; sexual symptoms of lack of lubrication, discomfort or pain, and impaired function; and urinary symptoms of urgency, dysuria and recurrent urinary tract infections. Women may present with some or all of the signs and symptoms, which must be bothersome and should not be better accounted for by another diagnosis. The term was presented and discussed at the annual meeting of each society. The respective Boards of NAMS and ISSWSH formally endorsed the new terminology--genitourinary syndrome of menopause (GSM)--in 2014.

    Ureaplasma diversum infection in bovine females may result in various reproductive problems, including granular vulvovaginitis, abortion, weak calves, salpingitis, and spontaneous abortion. The presence of U. diversum in a dairy bovine population from midwestern Brazil has not been established. The aim of this study was to determine whether U. diversum was present in dairy cattle from midwestern Brazil using polymerase chain reaction (PCR). Vulvovaginal mucus was analyzed from 203 cows located in six municipalities in the north region of Mato Grosso State, Brazil. A total of 25% of dairy cows with vulvovaginitis were positive for U. diversum. The factors evaluated were included in a multivariable logistic regression model with the presence of at least one positive cow in the herd serving as the dependent variable. Three variables were significantly associated with a U. diversum-positive PCR and were included in the final multivariable model: number of parities, vulvar lesions, and reproductive problems. For each new parity, the chance of U. diversum infection decreased 0.03-fold, indicating that cows with the highest number of parities were more protected. The presence of vulvar lesions was increased 17.6-fold in females positive for U. diversum, suggesting that this bacterium could be related to the red granular lesions in the vulvar mucosa, whereas reproductive problems were increased 7.6-fold. However, further investigations should be conducted to ascertain the effects of U. diversum in association with other mycoplasma species in the herds studied.

    Towards the end of the 19th century, Europe turned particular attention to the problem of tuberculosis, at that time the most serious social disease. In the majority of cases, pulmonary tuberculosis had a fatal outcome owing to the lack of effective drugs and methods of treatment. Due to poor sanitary conditions, particularly as regards dwellings, pulmonary tuberculosis was able to spread rapidly. Hospital departments were reluctant to admit patients suffering from tuberculosis. It was only after the discoveries of Robert Koch (bacillus tubercle in 1882) that the cause of the disease became understood and methods of treatment began to be developed. A modern sanatorium and hospital with 270 beds was erected in Hohenkrug (today Szczecin-Zdunowo) between 1915 and 1930. Patients could now be treated with modern methods, surgically in most cases. After the Second World War, pulmonary tuberculosis was still an enormous epidemiologic problem. In 1949, the Polish authorities opened a 400-bed sanatoriumin Zdunowo. The methods of treatment were not much different from pre-war practice and it was only the routine introduction of antituberculotic drugs during the fifties of the past century that brought about a radical change in the fight against tuberculosis. The growing numbers of patients with tuberculosis of the genitourinary system led to the opening in 1958 of a 40-bed specialist ward at the Tuberculosis Sanatorium in Zdunowo. It should be emphasized that the Department of Genitourinary Tuberculosis in Szczecin-Zdunowo was a historical necessity and a salvation for thousands of patients from Northern Poland. The Department totally fulfilled its social duties thanks to the commitment of many outstanding persons dedicated to helping the patients. This unit was finally closed in 1987 because the demand for surgical treatment of tuberculosis was declining concurrently with the advent of new and potent antituberculotics and falling number of new cases of genitourinary

    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.

    A study of the potential biological effects of veralipride was conducted in female rats. A definite stimulating action on the mammary gland was noted, but doses of 5 to 20 mg/kg/day are required to produce secretion, which is varying from one animal to another. Follicular maturation is preserved, though there is an increase in the number of corpora lutea with more marked development in some of them. Progesterone impregnation of the uterus occurs in a variable way and then only at doses of 5 + 0 20 mg/kg/day. Vaginal mucification, from a reduction in estrogen in relation to progesterone impregnation, is noted after 1 mg/kg/day (though 25 p. cent of the animals still demonstrate vaginal keratinization after 20 mg/kg/day). Finally, degranulation of the carminophile cells of the anterior pituitary gland, occurs after 5 mg/kg/day.

    HIV transmission across the genital mucosa is a major mode of new HIV infections in women. The probability of infection may be influenced by several factors including recruitment and activation of HIV target cells, such as dendritic cells (DCs) and cytokine production, associated with genital inflammation. We evaluated the role of inflammatory cytokines and TLR signaling in migration and activation of genital tract DCs in the human cervical explant model. Hysterectomy tissues from 10 HIV-negative and 7 HIV-positive donor women were separated into ecto- and endocervical explants, and incubated with inflammatory cytokines (TNF-α, IL-1β, IL-8, MIP-1β) or agonists for TLR4 (LPS), TLR2/1 (PAM3) and TLR7/8 (R848). Migration (frequency) and activation (HLA-DR expression) of myeloid and plasmacytoid DCs and Langerhans cells were measured by flow cytometry. We observed that cytokines, LPS and PAM3 induced activation of migrating myeloid and plasmacytoid DCs. LPS induced a 3.6 fold lower levels of migration of plasmacytoid DCs from HIV-infected women compared with HIV-uninfected women (median activation indices of 2.932 vs 0.833). There was however a 4.5 fold increase in migration of Langerhans cells in HIV-infected compared with HIV-uninfected women in response to cytokines (median activation indices of 3.539 vs 0.77). Only TLR agonists induced migration and activation of DCs from endocervical explants. Hormonal contraception use was associated with an increase in activation of DC subsets in the endo and ectocervical explants. We conclude that inflammatory signals in the female genital tract induced DC migration and activation, with possible important implications for HIV susceptibility of cervical tissues.

    Koalas (Phascolarctos cinereus) are iconic Australian marsupials currently threatened by several processes, including infectious diseases and ecological disruption. Infection with Chlamydia pecorum, is considered a key driver of population decline. The clinical sign of 'wet bottom', a staining of the rump associated with urinary incontinence, is often caused by chlamydial urinary tract infections. However, wet bottom has been recorded in koalas free of C. pecorum, suggesting other causative agents in those individuals. We used 16S rRNA diversity profiling to investigate the microbiome of the urogenital tract of ten female koalas in order to identify potential causative agents of wet bottom, other than C. pecorum. Five urogenital samples were processed from koalas presenting with wet bottom and five were clinically normal. All koalas were negative for C. pecorum infection. We detected thirteen phyla across the ten samples, with Firmicutes occurring at the highest relative abundance (77.6%). The order Lactobacillales, within the Firmicutes, comprised 70.3% of the reads from all samples. After normalising reads using DESeq2 and testing for significant differences (P < 0.05), there were 25 operational taxonomic units (OTUs) more commonly found in one group over the other. The families Aerococcaceae and Tissierellaceae both had four significantly differentially abundant OTUs. These four Tissierellaceae OTUs were all significantly more abundant in koalas with wet bottom. This study provides the foundation for future investigations of causes of koala wet bottom, other than C. pecorum infection. This is of clinical relevance as wet bottom is often assumed to be caused by C. pecorum and treated accordingly. Our research highlights that other organisms may be causing wet bottom, and these potential aetiological agents need to be further investigated to fully address the problems this species faces.

    We compared the effects of extenders of frozen-thawed semen on post-thaw sperm characteristics and the distribution of frozen-thawed spermatozoa in the female genital tract after fixed-timed deep intrauterine insemination (DIUI) in sows. Frozen semen samples were thawed and diluted in either modified Modena solution (mMS) or porcine fertilization medium (PFM) containing theophylline, adenosine and cysteine. Sperm quality, assessed in vitro based on motility using a computer-assisted sperm analyzer and the integrity of the plasma and acrosomal membranes using flow cytometry, was evaluated at 0.5, 1.5, 3 and 6h after thawing. Progressive motility and the percentage of spermatozoa with damaged acrosomal membranes in PFM were significantly better than in mMS throughout the 6h. Sows with estrus synchronized using prostaglandin F2 alpha, equine chorionic gonadotropin and human chorionic gonadotropin (hCG) were inseminated once with mMS- or PFM-diluted 5 × 10(8) frozen-thawed spermatozoa by DIUI at 34 h after the hCG injection. At 4h after DIUI, reproductive tracts were recovered from 30 sows. There were significantly fewer polymorphonuclear leukocytes (PMNs) and more spermatozoa outside PMNs in the uterine horn after PFM treatment than with mMS. When 22 sows were administered DIUI with 10 × 10(8) frozen-thawed spermatozoa at 36 h after hCG, the pregnancy rates did not differ significantly between the mMS- (36%) and PFM- (64%) treated groups. Thus, PFM enhanced progressive sperm motility but increased sperm membrane damage compared with mMS; it also suppressed the migration of PMNs into the uterine lumen. Copyright © 2015 Elsevier B.V.

    Local mucosal cellular immunity is critical in providing protection from HSV-2. To characterize and quantify 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 with 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-cell 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 with 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.

    Most HIV infections are transmitted across mucosal epithelium. Understanding the role of innate and specific mucosal immunity in susceptibility or protection against HIV infection, as well as the effect of HIV infection on mucosal immunity, are of fundamental importance. HLA-G is a powerful modulator of the immune response. The aim of this study was to investigate whether soluble HLA-G (sHLA-G) expression in the female genital tract is associated with HIV-1 infection. Genital levels of sHLA-G were determined in 52 HIV-1-uninfected and 44 antiretroviral naïve HIV-1-infected female commercial sex workers (CSWs), as well as 71 HIV-1-uninfected non-CSW women at low risk of exposure, recruited in Cotonou, Benin. HIV-1-infected CSWs had higher genital levels of sHLA-G compared with those in both the HIV-1-uninfected CSW (P = 0.009) and non-CSW groups (P = 0.0006). The presence of bacterial vaginosis (P = 0.008), and HLA-G*01:01:02 genotype (P = 0.002) were associated with higher genital levels of sHLA-G in the HIV-1-infected CSWs, whereas the HLA-G*01:04:04 genotype was also associated with higher genital level of sHLA-G in the overall population (P = 0.038). When adjustment was made for all significant variables, the increased expression of sHLA-G in the genital mucosa remained significantly associated with both HIV-1 infection (P = 0.02) and bacterial vaginosis (P = 0.03). This study demonstrates that high level of sHLA-G in the genital mucosa is independently associated with both HIV-1 infection and bacterial vaginosis.

    A variety of drug-delivery platforms have been employed to deliver therapeutic agents across cervicovaginal mucus (CVM) and the vaginal mucosa, offering the capability to increase the longevity and retention of active agents to treat infections of the female reproductive tract (FRT). Nanoparticles (NPs) have been shown to improve retention, diffusion, and cell-specific targeting via specific surface modifications, relative to other delivery platforms. In particular, polymeric NPs represent a promising option that has shown improved distribution through the CVM. These NPs are typically fabricated from nontoxic, non-inflammatory, US Food and Drug Administration-approved polymers that improve biocompatibility. This review summarizes recent experimental studies that have evaluated NP transport in the FRT, and highlights research areas that more thoroughly and efficiently inform polymeric NP design, including mathematical modeling. An overview of the in vitro, ex vivo, and in vivo NP studies conducted to date - whereby transport parameters are determined, extrapolated, and validated - is presented first. The impact of different NP design features on transport through the FRT is summarized, and gaps that exist due to the limitations of iterative experimentation alone are identified. The potential of mathematical modeling to complement the characterization and evaluation of diffusion and transport of delivery vehicles and active agents through the CVM and mucosa is discussed. Lastly, potential advancements combining experimental and mathematical knowledge are suggested to inform next-generation NP designs, such that infections in the FRT may be more effectively treated.

    The majority of new HIV infections occur in women as a result of heterosexual intercourse, overcoming multiple innate barriers to infection within the mucosa. However, the avenues through which infection is established, and the nature of bottlenecks to transmission, have been the source of considerable investigation and contention. Using a high dose of a single round non-replicating SIV-based vector containing a novel dual reporter system, we determined the sites of infection by the inoculum using the rhesus macaque vaginal transmission model. Here we show that the entire female reproductive tract (FRT), including the vagina, ecto- and endocervix, along with ovaries and local draining lymph nodes can contain transduced cells only 48 hours after inoculation. The distribution of infection shows that virions quickly disseminate after exposure and can access target cells throughout the FRT, with an apparent preference for infection in squamous vaginal and ectocervical mucosa. JRFL enveloped virions infect diverse CD4 expressing cell types, with T cells resident throughout the FRT representing the primary target. These findings establish a new perspective that the entire FRT is susceptible and virus can reach as far as the ovary and local draining lymph nodes. Based on these findings, it is essential that protective mechanisms for prevention of HIV acquisition must be present at protective levels throughout the entire FRT to provide complete protection.

    Full Text Available 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.

    The objective of this study was to translate the International Consultation on Incontinence Modular Questionnaire for female lower urinary tract symptoms (ICIQ-FLUTS) into Sinhala and validate the Sinhala translation for use in clinical practice. The ICIQ-FLUTS was translated into Sinhala in accordance with the ICIQ validation protocol. The Sinhala translation was validated by administering it to 133 women with FLUTS, mainly urinary incontinence and or urgency, and to 118 women with symptoms other than FLUTS during the period 25 October 2013 to 23 December 2016, in the Academic Obstetrics and Gynaecology Unit, Teaching Hospital Mahamodara, Galle, Sri Lanka. The Sinhala translation had good content validity (assessed by a panel of clinicians including a content specialist, and a group of women with and without FLUTS), good internal consistency (Cronbach's alpha coefficient in the range 0.69-0.75) was stable (no significant differences between median test-retest scores in a subgroup of 24 women with FLUTS), had good construct validity (marked difference between median scores in women presenting with and without FLUTS, p urinary incontinence and/or urgency.

    What would be a potential impact of implementing the new ESHRE/European Society of Gynaecological Endoscopy (ESGE) female genital anomalies classification system on the management of women with previous diagnosis of arcuate uteri based on the modified American Society for Reproductive Medicine (ASRM) criteria? A significant number of women with previous diagnosis of arcuate uteri are reclassified as having partial septate uteri according to the new ESHRE/ESGE classification system which may increase the number of remedial surgical procedures. The ESHRE/ESGE classification system has defined measurement techniques, reference points and specific cut-offs to facilitate the differentiation between normal and septate uteri. These criteria have been arbitrarily defined and they rely on the measurement of uterine wall thickness and depth of distortion of uterine fundus. This was a retrospective cohort study. We searched our ultrasound clinic database from January 2011 to December 2014 to identify all women diagnosed with arcuate uterus on three-dimensional ultrasound according to the modified ASRM criteria. For each woman, the ultrasound images were stored in our clinical database and they were re-examined according to ESHRE/ESGE specifications. The presence and location of all acquired uterine anomalies, such as fibroids or adenomyosis was noted. We applied the two diagnostic approaches as specified by the ESHRE/ESGE classification: the main option (MO) and the alternative option (AO). We used the Kappa statistic to quantify the agreement between the two approaches. We also compared the number of previous miscarriages in women with normal and partial septate uteri according to the ESHRE/ESGE classification. Non-parametric Mann-Whitney and Kruskal-Wallis tests were used for the analyses and receiver-operating characteristic curves were constructed to assess the predictive values of the calculated uterine distortion indices for the detection of women at risk of suffering

    Common uterine anomalies are important owing to their impact on fertility, and complex mesonephric anomalies and certain Müllerian malformations are particularly important because they cause serious clinical symptoms and affect woman's quality of life, in addition to creating fertility problems. In these cases of complex female genital tract malformations, a correct diagnosis is essential to avoid inappropriate and/or unnecessary surgery. Therefore, acquiring and applying the appropriate embryological knowledge, management and therapy is a challenge for gynaecologists. Here, we considered complex malformations to be obstructive anomalies and/or those associated with cloacal and urogenital sinus anomalies, urinary and/or extragenital anomalies, or other clinical implications or symptoms creating a difficult differential diagnosis. A diligent and comprehensive search of PubMed and Scopus was performed for all studies published from 1 January 2011 to 15 April 2015 (then updated up to September 2015) using the following search terms: 'management' in combination with either 'female genital malformations' or 'female genital tract anomalies' or 'Müllerian anomalies'. The MeSH terms 'renal agenesis', 'hydrocolpos', 'obstructed hemivagina' 'cervicovaginal agenesis or atresia', 'vaginal agenesis or atresia', 'Herlyn-Werner-Wunderlich syndrome', 'uterine duplication' and 'cloacal anomalies' were also used to compile a list of all publications containing these terms since 2011. The basic embryological considerations for understanding female genitourinary malformations were also revealed. Based on our experience and the updated literature review, we studied the definition and classification of the complex malformations, and we analysed the clinical presentation and different therapeutic strategies for each anomaly, including the embryological and clinical classification of female genitourinary malformations. From 755 search retrieved references, 230 articles were analysed and

    Full Text Available Co-morbidity of bladder, bowel, and non-specific pelvic pain symptoms is highly prevalent in women. Little evidence is present on modulation of pelvic pain syndromes by sex hormones, therefore, the objective of this study was to clarify the effects of hormonal fluctuations within the estrous cycle on regulatory neuropeptides in female rats using a model of neurogenic bladder dysfunction. The estrous cycle in female rats (Sprague-Dawley, 230-250 g was assessed by vaginal smears and weight of uterine horns. Neurogenic bladder dysfunction was induced by a single inflammatory insult to the distal colon. Protein expression of calcitonin gene related peptide (CGRP, substance P (SP, nerve growth factor (NGF, and brain derived neurotrophic factor (BDNF in the pelvic organs, sensory ganglia and lumbosacral spinal cord was compared in rats in proestrus (high estrogen vs diestrus (low estrogen. Under normal physiological conditions, concentration of SP and CGRP was similar in the distal colon and urinary bladder during all phases of the estrous cycle, however, acute colitis induced a significant up-regulation of CGRP content in the colon (by 63% and urinary bladder (by 54%, p≤0.05 to control of rats in proestrus. These changes were accompanied by a significant diminution of CGRP content in L6-S2 DRG after colonic treatment, likely associated with its release in the periphery. In rats with high estrogen at the time of testing (proestrus, experimental colitis caused a significant up-regulation of BDNF colonic content from 26.1±8.5 pg/ml to 83.4±32.5 pg/ml (N = 7, p≤0.05 to control and also induced similar effects on BDNF in the urinary bladder which was also up-regulated by 5-fold in rats in proestrus (p≤0.05 to respective control. Our results demonstrate estrous cycle dependent fluctuations of regulatory neuropeptides in the lower urinary tract upon colon-bladder cross-sensitization, which may contribute to pain fluctuations in female patients

    There are few guidelines and little data on imaging after urinary tract infections in older children. We determined the clinical yield of renal and bladder ultrasound, and voiding cystourethrogram in older children and adolescents after urinary tract infection. We analyzed findings on voiding cystourethrogram, and renal and bladder ultrasound as well as the clinical history of patients who underwent the 2 studies on the same day between January 2006 and December 2010. We selected for study patients 5 to 18 years old who underwent imaging for urinary tract infection. Those with prior postnatal genitourinary imaging or prenatal hydronephrosis were excluded from analysis. We identified a cohort of 153 patients, of whom 74% were 5 to 8 years old, 21% were 8 to 12 years old and 5% were 12 to 18 years old. Of the patients 77% were female, 78% had a febrile urinary tract infection history and 55% had a history of recurrent urinary tract infections. Renal and bladder ultrasound findings revealed hydronephrosis in 7.8% of patients, ureteral dilatation in 3.9%, renal parenchymal findings in 20% and bladder findings in 12%. No patient had moderate or greater hydronephrosis. Voiding cystourethrogram showed vesicoureteral reflux in 34% of cases and bladder or urethral anomalies in 12%. Reflux was grade I, II-III and greater than III in 5.9%, 26% and 2% of patients, respectively. For any voiding cystourethrogram abnormality the sensitivity and specificity of any renal and bladder ultrasound abnormality were 0.49 (95% CI 0.37-0.62) and 0.76 (95% CI 0.66-0.84), respectively. Positive and negative predictive values were 0.58 (95% CI 0.44-0.71) and 0.69 (0.59-0.77), respectively. In older children with a history of urinary tract infection the imaging yield is significant. However, imaging revealed high grade hydronephrosis or high grade vesicoureteral reflux in few patients. Renal ultrasound is not reliable for predicting voiding cystourethrogram findings such as vesicoureteral

    Full Text Available OBJECTIVE:tthis study aimed to investigate the incidence of premature rupture of fetal membranes in preterm singleton pregnancies and its association with sociodemographic factors and maternal self-reported genitourinary infections.METHODS:this was a population-based cross-sectional study, which included all mothers of newborns of singleton deliveries that occurred in 2010, with birth weight > 500 grams, who resided in the city of Rio Grande. Women were interviewed in the two maternity hospitals. Cases were women who had lost amniotic fluid before hospitalization and whose gestational age was less than 37 weeks. Statistical analysis was performed by levels to control for confounding factors using Poisson regression.RESULTS:of the 2,244 women eligible for the study, 3.1% had preterm premature rupture of fetal membranes, which was more frequent, after adjustment, in women of lower socioeconomic status, (prevalence ratio [PR] = 1.94, with lower level of schooling (PR = 2.43, age > 29 years (PR = 2.49, and smokers (PR = 2.04. It was also associated with threatened miscarriage (PR = 1.68 and preterm labor, (PR = 3.40. There was no association with maternal urinary tract infection or presence of genital discharge.CONCLUSIONS:the outcome was more common in puerperal women with lower level of schooling, lower socioeconomic status, older, and smokers, as well as those with a history of threatened miscarriage and premature labor. These factors should be considered in the prevention, diagnosis, and therapy approach.

  2. Protein-coated nanoparticles are internalized by the epithelial cells of the female reproductive tract and induce systemic and mucosal immune responses.

    Full Text Available The female reproductive tract (FRT includes the oviducts (fallopian tubes, uterus, cervix and vagina. A layer of columnar epithelium separates the endocervix and uterus from the outside environment, while the vagina is lined with stratified squamous epithelium. The mucosa of the FRT is exposed to antigens originating from microflora, and occasionally from infectious microorganisms. Whether epithelial cells (ECs of the FRT take up (sample the lumen antigens is not known. To address this question, we examined the uptake of 20-40 nm nanoparticles (NPs applied vaginally to mice which were not treated with hormones, epithelial disruptors, or adjuvants. We found that 20 and 40 nm NPs are quickly internalized by ECs of the upper FRT and within one hour could be observed in the lymphatic ducts that drain the FRT, as well as in the ileac lymph nodes (ILNs and the mesenteric lymph nodes (MLNs. Chicken ovalbumin (Ova conjugated to 20 nm NPs (NP-Ova when administered vaginally reaches the internal milieu in an immunologically relevant form; thus vaginal immunization of mice with NP-Ova induces systemic IgG to Ova antigen. Most importantly, vaginal immunization primes the intestinal mucosa for secretion of sIgA. Sub-cutaneous (s.c boosting immunization with Ova in complete Freund's adjuvant (CFA further elevates the systemic (IgG1 and IgG2c as well as mucosal (IgG1 and sIgA antibody titers. These findings suggest that the modes of antigen uptake at mucosal surfaces and pathways of antigen transport are more complex than previously appreciated.

    The aim of this study was to investigate the efficacy of extracorporeal magnetic stimulation (EMS) for the treatment of bothersome and severe symptoms of stress urinary incontinence (SUI) and overactive bladder syndrome (OAB) in female patients. A retrospective review was conducted on patients with SUI and OAB who were referred to EMS therapy. Successful treatment for the bothersome symptoms of OAB and SUI was defined as score ≤1 for questions 2 and 3 on the Urodynamic Distress Inventory-6. The objective cure of SUI and OAB was defined as no urinary leakage during the cough stress test and any urgency, urge incontinence and voiding frequency of less than eight times per 24 h based on the 3-day bladder diary, after the 9 weeks of treatment, respectively. Ninety-three patients with SUI or OAB underwent a 9-week course of EMS at 20 min twice weekly. Seventy-two (77%) patients completed EMS treatment. Geographical factor and poor economic status were two main factors for dropout. A total of 94.1% (32 of 34) and 86.8% (33 of 38) of subjects had successful treatment for the bothersome symptoms of OAB and SUI, respectively. In contrast, the cure rate for OAB and SUI was only 61.7% and 42.1%, respectively. There was also a significant improvement in both Urogenital Distress Inventory Short Form (bothersome on lower urinary tract symptoms) and the Incontinence Impact Questionnaire Short Form (quality of life) total score in both groups after EMS. EMS is a safe and effective alternative method for treating SUI and OAB. Further studies are needed to evaluate the long-term efficacy. © 2013 The Authors.

    The female genital tract (FGT) microbiome may affect vaginal pH and other factors that influence drug movement into the vagina. We examined the relationship between the microbiome and antiretroviral concentrations in the FGT. Over one menstrual cycle, 20 human immunodeficiency virus (HIV)-infected women virologically suppressed on tenofovir (TFV) disoproxil fumarate/emtricitabine and ritonavir-boosted atazanavir (ATV) underwent serial paired cervicovaginal and plasma sampling for antiretroviral concentrations using high-performance liquid chromatography-tandem mass spectrometry. Analysis of 16S ribosomal RNA gene sequencing of cervicovaginal lavage clustered each participant visit into a unique microbiome community type (mCT). Participants were predominantly African American (95%), with a median age of 38 years. Cervicovaginal lavage sequencing (n = 109) resulted in a low-diversity mCT dominated by Lactobacillus (n = 40), and intermediate-diversity (n = 28) and high-diversity (n = 41) mCTs with abundance of anaerobic taxa. In multivariable models, geometric mean FGT:plasma ratios varied significantly by mCT for all 3 drugs. For both ATV and TFV, FGT:plasma was significantly lower in participant visits with high- and low-diversity mCT groups (all P < .02). For emtricitabine, FGT:plasma was significantly lower in participant visits with low- vs intermediate-diversity mCT groups (P = .002). Certain FGT mCTs are associated with decreased FGT antiretroviral concentrations. These findings are relevant for optimizing antiretrovirals used for biomedical HIV prevention in women. © The Author 2017.

    The female genital tract is not exposed to seminal plasma during standard assisted reproductive technology (ART) cycles. However, it is thought that the inflammatory reaction triggered by seminal plasma may be beneficial by inducing maternal tolerance to paternal antigens expressed by the products of conception, and may increase the chance of successful implantation and live birth. To assess the effectiveness and safety of application of seminal plasma to the female genital tract prior to embryo transfer in ART cycles. We searched the following databases from inception to October 2017: Cochrane Gynaecology and Fertility Group Specialised Register of Controlled Trials, Cochrane Central Register of Studies Online (CRSO), MEDLINE, Embase, CINAHL and PsycINFO. We also searched trial registers for ongoing trials, including International Clinical Trials Registry Platform (ICTRP) Search Portal and ClinicalTrials.gov. Other sources searched were; Web of Knowledge, OpenGrey, LILACS, PubMed, Google Scholar and the reference lists of relevant articles. We included randomised controlled trials (RCTs) conducted among women undergoing ART, comparing any procedure that would expose the female genital tract to seminal plasma during the period starting five days before embryo transfer and ending two days after it versus no seminal plasma application. Two review authors independently selected trials, assessed risk of bias, and extracted data. We pooled data to calculate relative risks (RRs) and 95% confidence intervals (CIs). We assessed statistical heterogeneity using the I 2 statistic. We assessed the overall quality of the evidence for the main outcomes using GRADE methods. Our primary outcomes were live birth rate and miscarriage rate. Secondary outcomes were live birth/ongoing pregnancy rate, clinical pregnancy rate, multiple pregnancy rate, ectopic pregnancy rate and the incidence of other adverse events. We included 11 RCTs (3215 women). The quality of the evidence ranged

    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. 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. 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 follicular phase (p=0·0488), suggesting that a

    This article reviews the computed tomography and magnetic resonance imaging (MRI) features of renal tuberculosis (TB), including TB in transplant recipients and immunocompromised patients. Multi detector computed tomography (MDCT) forms the mainstay of cross-sectional imaging in renal TB. It can easily identify calcification, renal scars, mass lesions, and urothelial thickening. The combination of uneven caliectasis, with urothelial thickening and lack of pelvic dilatation, can also be demonstrated on MDCT. MRI is a sensitive modality for demonstration of features of renal TB, including tissue edema, asymmetric perinephric fat stranding, and thickening of Gerota's fascia, all of which may be clues to focal pyelonephritis of tuberculous origin. Diffusion-weighted MR imaging with apparent diffusion coefficient (ADC) values may help in differentiating hydronephrosis from pyonephrosis. ADC values also have the potential to serve as a sensitive non-invasive biomarker of renal fibrosis. Immunocompromised patients are at increased risk of renal TB. In transplant patients, renal TB, including tuberculous interstitial nephritis, is an important cause of graft dysfunction. Renal TB in patients with HIV more often shows greater parenchymal affection, with poorly formed granulomas and relatively less frequent findings of caseation and stenosis. Atypical mycobacterial infections are also more common in immunocompromised patients

    Approximately 70% of all suicides in patients aged >60 years are attributed to physical illness, with higher rates noted in patients with cancer. The purpose of the current study was to characterize suicide rates among patients with genitourinary cancers and identify factors associated with suicide in this specific cohort. Patients with prostate, bladder, kidney, testis, and penile cancer were identified in the Surveillance, Epidemiology, and End Results database (1988-2010). Standardized mortality ratios (SMRs) and 95% confidence intervals (95% CIs) were calculated for each anatomic site. Multivariable logistic regression models generated odds ratios (ORs) for the identification of factors associated with suicide for each malignancy. There were 2268 suicides identified among 1,239,522 individuals with genitourinary malignancies observed for 7,307,377 person-years. The SMRs for patients with cancer were 1.37 for prostate cancer (95% CI, 0.99-1.86), 2.71 for bladder cancer (95% CI, 2.02-3.62), 1.86 for kidney cancer (95% CI, 1.32-2.62), 1.23 for testis cancer (95% CI, 0.88-1.73), and 0.95 for penile cancer (95% CI, 0.65-1.35). On multivariable analysis, male sex was found to be associated with odds of suicide among patients with bladder cancer (OR, 6.63) and kidney cancer (OR, 4.98). Increasing age was associated with suicide for patients with prostate, bladder, and testis cancer (OR range, 1.03-1.06). Distant disease was associated with suicide in patients with prostate, bladder, and kidney cancer (OR range, 2.82-5.43). Among patients with prostate, bladder, and kidney cancer, African American patients were less likely to commit suicide compared with white individuals (OR range, 0.26-0.46). Suicide in patients with genitourinary malignancies poses a public health dilemma, especially among men, the elderly, and those with aggressive disease.

    Sexual behavior is the dominant mode of HIV transmission in China, and young female migrants are among the populations at highest risk. This article examines how HIV-related risk behaviors among female migrants might vary according to workplace settings. Participants were young female migrants recruited from three workplace settings-factories, restaurants and entertainment venues. In a cross-sectional survey, we assessed 457 participants' sociodemographic characteristics, HIV/AIDS-related knowledge, condom use knowledge, sexual behaviors, condom use behavior and reproductive health factors. Participants working in entertainment venues were significantly more likely than those working in factories and restaurants to report sexual behavior, unprotected sex, multiple pregnancy terminations and sexually transmitted infections (STI). However, participants working in factories and restaurants reported significantly lower levels of HIV/AIDS knowledge, condom use knowledge, condom use self-efficacy and history of HIV/AIDS counseling and testing. Independent correlates of unprotected sex included employment in an entertainment venue, abortion history and sexual self-efficacy. Independent correlates of STI or genitourinary tract infection included employment in an entertainment venue, abortion history, recent migration and recent unprotected sex. These findings indicate a need for sexual and reproductive health interventions prioritizing young female migrants, and call for programs that can be incorporated into different workplace settings. © The Author 2015.

    Urinary infection is the most common bacterial infection in elderly populations. The high prevalence of asymptomatic bacteriuria in both men and women is benign and should not be treated. A diagnosis of symptomatic infection for elderly residents of long-term care facilities without catheters requires localizing genitourinary findings. Symptomatic urinary infection is overdiagnosed in elderly bacteriuric persons with nonlocalizing clinical presentations, with substantial inappropriate antimicrobial use. Residents with chronic indwelling catheters experience increased morbidity from urinary tract infection. Antimicrobial therapy is selected based on clinical presentation, patient tolerance, and urine culture results. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Objective: this study aimed to investigate the incidence of premature rupture of fetal membranes in preterm singleton pregnancies and its association with sociodemographic factors and maternal self-reported genitourinary infections. Methods: this was a population-based cross-sectional study, which included all mothers of newborns of singleton deliveries that occurred in 2010, with birth weight ≥ 500 grams, who resided in the city of Rio Grande. Women were interviewed in the two maternity hospitals. Cases were women who had lost amniotic fluid before hospitalization and whose gestational age was less than 37 weeks. Statistical analysis was performed by levels to control for confounding factors using Poisson regression. Results: of the 2,244 women eligible for the study, 3.1% had preterm premature rupture of fetal membranes, which was more frequent, after adjustment, in women of lower socioeconomic status, (prevalence ratio [PR] = 1.94, with lower level of schooling (PR = 2.43, age > 29 years (PR = 2.49, and smokers (PR = 2.04. It was also associated with threatened miscarriage (PR = 1.68 and preterm labor, (PR = 3.40. There was no association with maternal urinary tract infection or presence of genital discharge. Conclusions: the outcome was more common in puerperal women with lower level of schooling, lower socioeconomic status, older, and smokers, as well as those with a history of threatened miscarriage and premature labor. These factors should be considered in the prevention, diagnosis, and therapy approach.

  19. Maximizing outcomes in genitourinary cancers across the treatment continuum.

    2011-04-01

    Key controversies concerning the management of genitourinary cancers across the treatment continua were discussed at the second annual Interactive Genitourinary Cancer Conference (IGUCC) held in February 2010 in Athens, Greece. Prostate cancer is the most common form of cancer among western men and prevention strategies are needed. Trials evaluating 5α-reductase inhibitors have reported beneficial and clinically meaningful results, but uptake remains low for primary prostate cancer prevention. Prostate cancer detection programmes are also important as curative treatments for advanced disease are unavailable. Two large landmark randomized controlled trials reported conflicting results concerning screening efficacy and uncovered high levels of over-diagnosis and potential over-treatment. Tailored management strategies after diagnosis are important and predictive markers that distinguish between aggressive and indolent tumours are needed. The majority of newly diagnosed cases of prostate cancer are clinically localized. Active surveillance of favourable risk patients may be beneficial in the intermediate term, while an integrated approach of multi-modality therapy in patients with adverse features is recommended. The benefits of new technologies such as high-intensity focused ultrasound (HIFU) and robotic prostatectomy have not been established in prospective randomized trials vs current standards of care. A multidisciplinary approach is essential to evolving the management of advanced prostate cancer into a chronic disease paradigm. Docetaxel plus prednisone is the standard first-line chemotherapy for patients with metastatic castration-resistant prostate cancer (mCRPC), but the optimal timing of chemotherapy initiation has not been addressed in randomized clinical trials. Retrospective analyses suggest that asymptomatic patients with adverse prognostic factors for survival may also benefit from receiving chemotherapy. Bladder cancer is a common malignancy and the

    Uro-genital fistulas, majority of which are vesico-vaginal fistulas (VVF), are a great challenge for women in developing countries. It is commonly caused by prolong obstructed labour and is one of the worst complications of child birth and poor obstetric care. The objective of this descriptive study was to review the cases of genitourinary fistulae so as to understand the magnitude of the problem and its aetiology and to share our experience of surgical repair with other specialists in this field. The study was conducted at Gynaecological Unit-II, Liaquat University Hospital Hyderabad, Pakistan from June 1996 to December 2007. The case records of all patients admitted and managed during study period were reviewed. The information regarding characteristics, risk factors and surgical management was collected. The data was analysed by SPSS and mean, range, standard deviation and percentage were calculated. During the study period, 278 patients with genitourinary fistulae were admitted and managed. The mean age of patients with urinary fistulae was 31.5+-7.5 years, parity was 4.2+-2.8, and duration of labour was 38.4+-6.5 hours. The duration of fistulae ranged from 1 day to 25 years. Obstructed labour 246 (88.4%) was the most common cause of urinary fistulae, followed by gynaecological surgeries mainly hysterectomies 26 (9.35%). The most common type of urinary fistula was vesico-vaginal fistula (VVF) 250 (89.9%). A total of 268 underwent surgery. Almost all 261 (97.3%) urinary fistulae were repaired transvaginally except patients with ureterovaginal and vesico-uterine fistulae. The most common surgical procedure used was layered closure. Martius graft was used in 3 (1.1%) patients, who required creation of new urethra. The success rate following first, second and third attempt was 85%, 91% and 96% respectively. Urogenital fistulae are rarity in developed world, but are frequently encountered problem in developing countries like Pakistan, often resulting from prolonged

    Prostate cancer is the most common cancer among North American and European men, but its treatment continues to be problematic owing to serious side-effects, including erectile dysfunction, urinary incontinence, and potential lower GI complications. Robotic radiosurgery offers a novel, rapid, non-invasive outpatient treatment option for prostate cancer that combines robotics, advanced image-guided motion detection, and automated real-time corrective spatial positioning with submillimeter precision. This book examines all aspects of the treatment of prostate cancer with robotic radiosurgery. After introductory sections on radiosurgery as a multidisciplinary practice and specific issues relating to prostate cancer, the important challenge posed by prostate motion when administering radiation therapy is examined in depth, with detailed discussion as to how image-guided robotic radiosurgery overcomes this problem by continously identifying the precise location of the prostate throughout the course of treatment. A further major section is devoted to a discussion of techniques and potential radiobiological and clinical advantages of hypofractionated radiation delivery by means of robotic radiosurgery systems. The book closes by discussing other emerging genitourinary applications of robotic radiosurgery. All of the authors are experts in their field who present a persuasive case for this fascinating technique. (orig.)

    Antiretroviral drug absorption and disposition in cervicovaginal tissue is important for the effectiveness of vaginally or orally administered drug products in preexposure prophylaxis (PrEP) of HIV-1 sexual transmission to women. Therefore, it is imperative to understand critical determinants of cervicovaginal tissue pharmacokinetics. This study aimed to examine the mRNA expression and protein localization of three efflux transporters, P-glycoprotein (P-gp), multidrug resistance-associated protein 4 (MRP4), and breast cancer resistance protein (BCRP), in the lower genital tract of premenopausal women and pigtailed macaques. Along the human lower genital tract, the three transporters were moderately to highly expressed compared to colorectal tissue and liver, as revealed by real-time reverse transcriptase polymerase chain reaction (RT-PCR). In a given genital tract segment, the transporter with the highest expression level was either BCRP or P-gp, while MRP4 was always expressed at the lowest level among the three transporters tested. The immunohistochemical staining showed that P-gp and MRP4 were localized in multiple cell types including epithelial cells and vascular endothelial cells. BCRP was predominantly localized in the vascular endothelial cells. Differences in transporter mRNA level and localization were observed among endocervix, ectocervix, and vagina. Compared to human tissues, the macaque cervicovaginal tissues displayed comparable expression and localization patterns of the three transporters, although subtle differences were observed between the two species. The role of these cervicovaginal transporters in drug absorption and disposition warrants further studies. The resemblance between human and pigtailed macaque in transporter expression and localization suggests the utility of the macaque model in the studies of human cervicovaginal transporters.

    C. trachomatis and C. abortus are related Gram-negative intracellular bacteria that cause reproductive failure due to infertility (C. trachomatis) or abortion (C. abortus). These organisms target epithelial cells in the reproductive tract and/or placenta, but the innate immune mechanisms that lead to protection or pathology and disease are poorly understood. SLPI is an innate immune molecule which protects mucosal surfaces from infection and injury. C. trachomatis and C. abortus were found to induce SLPI mRNA and peptide expression in HeLa (cervical epithelium) and JEG-3 cells (trophoblast) respectively. Both cell lines constitutively expressed SLPI and, although infection enhanced this expression, killed organisms did not. These data demonstrate that Chlamydia/Chlamydophila grow in cells that express SLPI, suggesting that SLPI does not exert antimicrobial effects against these organisms. However, SLPI has multiple functions, and we speculate that it may play a role in controlling tissue inflammation and pathology.

    Fresh ram sperma or sperm-free seminal plasma, labelled with 131 I was intracervically applied to 7 ewes with an estrus synchronised by means of PGF/sub 2α/. The animals were slaughtered at different dates after insemination. The genital tract of the sheep was cut into 14 sections which were all measured for radioactivity. Seminal plasma was found to have undergone transcervical and transuterine passage, which produced evidence to the effect that the uterine cervix of sheep was permeable to seminal plasma. 'Barrier effects' of the cervix were of different strength, depending on individuals. Labelled sperma was quantitatively detected also from the upper genital regions, which seemed to support the assumption that sperm storage function had to be attributed not only to the uterine cervix of sheep, but also to the uterotubal canal. Asymmetry was observed in distribution between left and right uterus cornua and oviducts. (author)

    Post-surgical infections (PSIs) are a source of preventable perioperative morbidity. No guidelines exist for the use of perioperative antibiotics in pediatric urologic procedures. This study reports the rate of PSIs in non-endoscopic pediatric genitourinary procedures at our institution. Secondary aims evaluate the association of PSI with other perioperative variables, including wound class (WC) and perioperative antibiotic administration. Data from consecutive non-endoscopic pediatric urologic procedures performed between August 2011 and April 2014 were examined retrospectively. The primary outcome was the rate of PSIs. PSIs were classified as superficial skin (SS) and deep/organ site (D/OS) according to Centers for Disease Control and Prevention guidelines, and urinary tract infection (UTI). PSIs were further stratified by WC1 and WC2 and perioperative antibiotic usage. A relative risk and chi-square analysis compared PSI rates between WC1 and WC2 procedures. A total of 1185 unique patients with 1384 surgical sites were reviewed; 1192 surgical sites had follow-up for inclusion into the study. Ten total PSIs were identified, for an overall infection rate of 0.83%. Of these, six were SS, one was D/OS, and three were UTIs. The PSI rate for WC1 (885 sites) and WC2 (307 sites) procedures was 0.34% and 2.28%, respectively, p antibiotics (0.35% vs. 0.33%). All WC2 procedures received antibiotics. Post-surgical infections are associated with significant perioperative morbidity. In some studies, PSI can double hospital costs, and contribute to hospital length of stay, admission to intensive care units, and impact patient mortality. Our study demonstrates that the rate of PSI in WC1 operations is low, irrespective of whether the patient received perioperative antibiotics (0.35%) or no antibiotics (0.33%). WC2 operations were the larger source of morbidity with an infection rate of 2.28% and a 6.7 fold higher increase in relative risk. WC1 procedures have a rate of

    In up to 10% of patients who experience abdominal trauma, renal and urogenital systems will be involved. In polytrauma patients with other potentially life-threatening injuries, renal and genitourinary trauma may be overlooked initially, but a delayed or missed diagnosis of these injuries may result in preventable complications. This review provides a best-practice approach to the diagnosis and management of renal and genitourinary injuries, with an emphasis on the systematic approach needed to identify subtle injuries and avoid long-term urinary sequelae such as hypertension, incontinence, erectile dysfunction, chronic kidney disease, and nephrectomy.

    2008-01-01

    Full Text Available There is growing evidence that male as well as female reproductive function has been declining in human and wildlife populations over the last 40 years. Several factors such as lifestyle or environmental xenobiotics other than genetic factors may play a role in determining adverse effects on reproductive health. Among the environmental xenobiotics phthalates, a family of man-made pollutants are suspected to interfere with the function of the endocrine system and therefore to be endocrine disruptors. The definition of endocrine disruption is today extended to broader endocrine regulations, and includes activation of metabolic sensors, such as the peroxisome proliferator-activated receptors (PPARs. Toxicological studies have shown that phthalates can activate a subset of PPARs. Here, we analyze the epidemiological and experimental evidence linking phthalate exposure to both PPAR activation and adverse effects on male and female reproductive health.

    Full Text Available Preclinical and early phase clinical microbicide studies have not consistently predicted the outcome of efficacy trials. To address this gap, candidate biomarkers of microbicide pharmacodynamics and safety were evaluated in a double-blind, placebo-controlled trial of tenofovir gel, the first microbicide to demonstrate significant protection against HIV acquisition.30 women were randomized to apply a single daily dose of tenofovir or placebo gel for 14 consecutive days. Anti-HIV activity was measured in cervicovaginal lavage (CVL on Days 0, 3, 7, 14 and 21 by luciferase assay as a surrogate marker of pharmacodynamics. Endogenous activity against E. coli and HSV-2 and concentrations of immune mediators were quantified in CVL as candidate biomarkers of safety. Tenofovir levels were measured in CVL and blood.A significant increase in anti-HIV activity was detected in CVL from women who applied tenofovir gel compared to their endogenous anti-HIV activity in genital tract secretions on Day 0 and compared to activity in CVL from women in the placebo group. The activity correlated significantly with CVL concentration of tenofovir (r = 0.6, p<0.001 and fit a sigmoid E(max pharmacodynamic model. Anti-HIV activity in CVL from women who applied tenofovir persisted when virus was introduced in semen, whereas endogenous anti-HIV activity decreased. Tenofovir did not trigger an inflammatory response or induce sustained loss in endogenous antimicrobial activity or immune mediators.Tenofovir gel had no deleterious impact on soluble mucosal immunity. The increased anti-HIV activity in CVL, which persisted in the presence of semen and correlated with tenofovir concentration, is consistent with the efficacy observed in a recent clinical trial. These results promote quantified CVL anti-HIV activity as a surrogate of tissue pharmacodynamics and as a potential biomarker of adherence to product. This simple, feasible and inexpensive bioassay may promote the development

    Young people attending genitourinary medicine services are at high risk of unplanned pregnancy. We performed a retrospective cohort study to identify characteristics of pregnant teenagers accessing an inner London genitourinary medicine service. There were 481 pregnancies in 458 teenagers with 54 previous pregnancies and 46 previous terminations of pregnancy. The under-18 and under-16 teenage pregnancy rates were 92.1 and 85.8 per 1000 age-matched clinic attendees, respectively. Median age was 17.1 years. 'Black Other' teenagers ('Black British', 'Mixed White-Black Caribbean' and 'Mixed White-Black African') were over-represented, compared to our clinic population, while those of White ethnicity were under-represented. Few pregnancies (1.5%) were planned with the majority (64%) intending terminations of pregnancy. Most teenagers did not use consistent contraception. Two-thirds of patients had attended genitourinary medicine services in the past and sexually transmitted infection prevalence at presentation was high. Effectively targeting the sexual and reproductive health needs of teenage genitourinary medicine clinic attendees may have a significant impact on reducing sexually transmitted infections, unplanned pregnancy and terminations of pregnancy in this group. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    The potential of magnetic resonance imaging (MRI) was evaluated in 21 female subjects: seven volunteers, 12 patients scanned for reasons unrelated to the lower genitourinary tract, and two patients referred with gynecologic disease. The uterus at several stages was examined; the premenarcheal uterus (one patient), the uterus of reproductive age (12 patients), the postmenopausal uterus (two patients), and in an 8 week pregnancy (one patient). The myometrium and cyclic endometrium in the reproductive age separated by a low-intensity line (probably stratum basale), which allows recognition of changes in thickness of the cyclic endometrium during the menstrual cycle. The corpus uteri can be distinguished from the cervix by the transitional zone of the isthmus. The anatomic relation of the uterus to bladder and rectum is easily outlined. The vagina can be distinguished from the cervix, and the anatomic display of the closely apposed bladder, vagina, and rectum is clear on axial and coronal images. The ovary is identified; the signal intensity from the ovary depends on the acquisition parameter used. Uterine leiomyoma, endometriosis, and dermoid cyst were depicted, but further experience is needed to ascertain the specificity of the findings

    To compare the clinical effectiveness of the intravesical administration of combined hyaluronic acid and chondroitin sulfate (HA+CS) versus current standard management in adult women with recurrent urinary tract infections (RUTIs). A European Union-based multicentre, retrospective nested case-control study. 276 adult women treated for RUTIs starting from 2009 to 2013. Patients treated with either intravesical administration of HA+CS or standard of care (antimicrobial/immunoactive prophylaxis/probiotics/cranberry). The primary outcome was occurrence of bacteriologically confirmed recurrence within 12 months. Secondary outcomes were time to recurrence, total number of recurrences, health-related quality of life and healthcare resource consumption. Crude and adjusted results for unbalanced characteristics are presented. 181 patients treated with HA+CS and 95 patients treated with standard of care from 7 centres were included. The crude and adjusted ORs (95% CI) for the primary end point were 0.77 (0.46 to 1.28) and 0.51 (0.27 to 0.96), respectively. However, no evidence of improvement in terms of total number of recurrences (incidence rate ratio (95% CI), 0.99 (0.69 to 1.43)) or time to first recurrence was seen (HR (95% CI), 0.99 (0.61 to 1.61)). The benefit of intravesical HA+CS therapy improves when the number of instillations is ≥ 5. Our results show that bladder instillations of combined HA+CS reduce the risk of bacteriologically confirmed recurrences compared with the current standard management of RUTIs. Total incidence rates and hazard rates were instead non-significantly different between the 2 groups after adjusting for unbalanced factors. In contrast to what happens with antibiotic prophylaxis, the effectiveness of the HA+CS reinstatement therapy improves over time. NCT02016118. Published by the BMJ Publishing Group Limited.

    The ADAMTS family comprises 19 secreted metalloproteinases that cleave extracellular matrix components and have diverse functions in numerous disease and physiological contexts. A number of them remain 'orphan' proteases and among them is ADAMTS18, which has been implicated in developmental eye disorders, platelet function and various malignancies. To assess in vivo function of ADAMTS18, we generated a mouse strain with inactivated Adamts18 alleles. In the C57Bl6/Ola background, Adamts18-deficient mice are born in a normal Mendelian ratio, and are viable but show a transient growth delay. Histological examination revealed a 100% penetrant eye defect resulting from leakage of lens material through the lens capsule occurring at embryonic day (E)13.5, when the lens grows rapidly. Adamts18-deficient lungs showed altered bronchiolar branching. Fifty percent of mutant females are infertile because of vaginal obstruction due to either a dorsoventral vaginal septum or imperforate vagina. The incidence of ovarian rete is increased in the mutant mouse strain.

    Full Text Available The ADAMTS family comprises 19 secreted metalloproteinases that cleave extracellular matrix components and have diverse functions in numerous disease and physiological contexts. A number of them remain ‘orphan’ proteases and among them is ADAMTS18, which has been implicated in developmental eye disorders, platelet function and various malignancies. To assess in vivo function of ADAMTS18, we generated a mouse strain with inactivated Adamts18 alleles. In the C57Bl6/Ola background, Adamts18-deficient mice are born in a normal Mendelian ratio, and are viable but show a transient growth delay. Histological examination revealed a 100% penetrant eye defect resulting from leakage of lens material through the lens capsule occurring at embryonic day (E13.5, when the lens grows rapidly. Adamts18-deficient lungs showed altered bronchiolar branching. Fifty percent of mutant females are infertile because of vaginal obstruction due to either a dorsoventral vaginal septum or imperforate vagina. The incidence of ovarian rete is increased in the mutant mouse strain. Thus, Adamts18 is essential in the development of distinct tissues and the new mouse strain is likely to be useful for investigating ADAMTS18 function in human disease, particularly in the contexts of infertility and carcinogenesis.

    Radiotherapy (RT) induced genitourinary (GU) morbidity is typically assessed by physicians as single symptoms or aggregated scores including symptoms from various domains. Here we apply a method to group patient-reported GU symptoms after RT for localized prostate cancer based on their interplay, and study how these relate to urinary bladder dose. Data were taken from two Scandinavian studies (N=207/276) including men treated with external-beam RT (EBRT) to 78/70Gy (2Gy/fraction; median time-to-follow-up: 3.6-6.4y). Within and across cohorts, bladder dose-volume parameters were tested as predictors for GU symptom domains identified from two study-specific questionnaires (35 questions on frequency, incontinence, obstruction, pain, urgency, and sensory symptoms) using univariate and multivariate logistic regression analysis (MVA) with 10-fold cross-validation. Performance was evaluated using Area Under the Receiver Operating Characteristic Curve (Az). For the identified Incontinence (2-5 symptoms), Obstruction (3-5 symptoms), and Urgency (2-7 symptoms) domains, MVA demonstrated that bladder doses close to the prescription doses were the strongest predictors for Obstruction (Az: 0.53-0.57) and Urgency (Az: 0.60). For Obstruction, performance increased for the across cohort analysis (Az: 0.61-0.64). Our identified patient-reported GU symptom domains suggest that high urinary bladder doses, and increased focus on both obstruction and urgency is likely to further add to the understanding of GU tract RT responses.

    Full Text Available Introduction : Accurate diagnosis of subepithelial lesions (SELs in the gastrointestinal tract depends on a variety of methods: endoscopy, endoscopic ultrasound and different types of biopsy. Making an error-free diagnosis is vital for the subsequent application of an appropriate treatment. Aim: To evaluate the efficacy of deep biopsy via the endoscopic submucosal dissection (ESD technique for SELs in the upper gastrointestinal tract. Material and methods: It was a case series study. Deep biopsy via the ESD technique was completed in 38 patients between November 2012 and October 2014. Thirty-eight SELs in the upper gastrointestinal tract of varying size (very small ≤ 1 cm, small 1–2 cm and large ≥ 2 cm by means of the ESD technique after an incision with an electrosurgical knife of the overlying layers and revealing a small part of the lesion were biopsied under direct endoscopic view. Results: Deep biopsy via the ESD technique was diagnostic in 28 of 38 patients (73.3%; 95% CI: 59.7–89.7%. The diagnostic yield for SELs with a clear endophytic shape increased to 91.3%. An evident endophytic appearance of a subepithelial lesion, the mean number of biopsied samples (6.65 ±1.36 and the total size in length of all samples per case (19.88 ±8.07 mm were the main criteria influencing the positiveness of deep biopsy in the diagnostic group compared to the nondiagnostic one (p = 0.001; p = 0.025; p = 0.008. Conclusions : Deep biopsy via the ESD technique is an effective and safe method for the diagnosis of SELs especially with a clear endophytic appearance in a large number of biopsied samples.

    Elevated inflammatory cytokines (EMCs) at mucosal surfaces have been associated with HIV susceptibility, but the underlying mechanisms remain unclear. We characterized the soluble mucosal proteome associated with elevated cytokine expression in the female reproductive tract. A scoring system was devised based on the elevation (upper quartile) of at least three of seven inflammatory cytokines in cervicovaginal lavage. Using this score, HIV-uninfected Kenyan women were classified as either having EMC (n=28) or not (n=68). Of 455 proteins quantified in proteomic analyses, 53 were associated with EMC (5% false discovery rate threshold). EMCs were associated with proteases, cell motility, and actin cytoskeletal pathways, whereas protease inhibitor, epidermal cell differentiation, and cornified envelope pathways were decreased. Multivariate analysis identified an optimal signature of 16 proteins that distinguished the EMC group with 88% accuracy. Three proteins in this signature were neutrophil-associated proteases that correlated with many cytokines, especially GM-CSF (granulocyte-macrophage colony-stimulating factor), IL-1β (interleukin-1β), MIP-3α (macrophage inflammatory protein-3α), IL-17, and IL-8. Gene set enrichment analyses implicated activated immune cells; we verified experimentally that EMC women had an increased frequency of endocervical CD4(+) T cells. These data reveal strong linkages between mucosal cytokines, barrier function, proteases, and immune cell movement, and propose these as potential mechanisms that increase risk of HIV acquisition.

    Between 1967 and 1982, 59 patients (33 with gynecologic malignancies and 26 with malignant tumors of the genitourinary system) received irradiation of 40 Gy or more for metastases to the para-aortic lymph nodes, in addition to pelvic irradiation. Disease in the para-aortic lymph nodes was controlled in 50 patients; the treatment failed in nine. Moderately acute side effects were seen in 25 patients, but none was severe. Late effects of irradiation were moderate in five patients and severe in three. Thirty patients are alive at 5 years. The benefits of local control and prolonged disease-free survival appear to outweigh considerably the risk of late effects from pelvic and para-aortic irradiation for advanced malignant tumors of the genitourinary system

    Full Text Available Genitourinary tuberculosis (GUTB is a rare extrapulmonary manifestation of tuberculosis (TB. Various forms of presentation are described and in most cases the disease results in calcification, atrophy, or necrosis of the renal parenchyma. The kidney is not generally palpable except in cases of hydronephrosis due to an upper ureteric stricture. We present a case of GUTB presenting as inflammatory pseudotumor. This case was initially diagnosed as renal malignancy and managed accordingly. Histopathology confirmed the diagnosis of pseudotumoral renal TB.

    Professor Rafael Molla Rodrigo is considered by some the author who contributed with his scientific work and solid technique to consolidate Urology as a speciality in Valencia. Such importance is also perceived in a national level, as demonstrated by the fact that he belonged to the first board of the Spanish Association of Urology and contributed to its foundation in the two-year period 1910--1911, from his position of head of the department of Surgical Therapy and Operations at the Central University. Genitourinary tuberculosis is one of the most outstanding chapters of his extensive works. We reviewed all his works, selecting all original articles about genitourinary tuberculosis. Original articles have been obtained from the journals Revista de Higiene y Tuberculosis, La Medicina Valenciana, Revista Valenciana de Ciencias Médicas y Policínica, and from his two most important books, Clinical Lessons In Urology and Clinical Lessons in Urology and Genitourinary Surgery. Throughout his work he analyzes features of relevance about this disease, such as diagnosis, about which he emphasizes the clinical and bacteriological difficulties, and treatment, which was only feasible by precocious nephrectomy. He dedicates a great part of his work to the study of this pathology and defends a precocious diagnosis in order to perform the only treatment that had demonstrated efficacy. He also exposes the symptoms and variety of clinical presentations, as well as diagnosis through separate kidney catheterization with the aim to determine unilateral involvement.

    The goal of this study was to describe a novel pattern of genitourinary (GU) anomalies in VACTERL association,which involves congenital anomalies affecting the vertebrae,anus, heart, trachea and esophagus, kidneys, and limbs.We collected clinical data on 105 patients diagnosed with VACTERL association and analyzed a subset of 89 patients who met more stringent inclusion criteria. Twenty-one percent of patients have GU anomalies, which are more severe (but not more frequent) in females. Anomalies were noted in patients without malformations affecting the renal, lower vertebral, or lower gastrointestinal systems. There should be a high index of suspicion for the presence of GU anomalies even in patients who do not have spatially similar malformations.

    To determine if urinary symptoms or urinary tract infections (UTI) were associated with sexually transmitted infections (STI) and which history, clinical, and laboratory findings could distinguish these infections in symptomatic women. A cross-sectional sample of 296 sexually active females aged 14-22 years attending a hospital-based teen health center or emergency department were recruited. Genitourinary symptoms, medical and sexual history, and urinalysis results were recorded. STI was defined as a vaginal swab positive for Trichomonas vaginalis or urine nucleic acid amplification test positive for Neisseria gonorrheae or Chlamydia trachomatis. A urine culture with >10,000 colonies of a single pathogen was considered a positive UTI. In the full sample, prevalence of UTI and STI were 17% and 33%, respectively. Neither urinary symptoms nor UTI was significantly associated with STI. Further analyses are reported for the 154 (51%) with urinary symptoms: Positive urine leukocytes, more than one partner in the last three months and history of STI predicted STI. Urinalysis results identified four groups: (1) Normal urinalysis-67% had no infection; (2) Positive nitrites or protein-55% had UTI; (3) Positive leukocytes or blood-62% had STI; and (4) Both nitrites/protein and leukocytes/blood positive-28% had STI and 65% had UTI. Those without a documented UTI were more likely to have trichomoniasis than those with a UTI, and 65% of those with sterile pyuria had STI, mainly trichomoniasis or gonorrhea. Adolescent females with urinary symptoms should be tested for both UTI and STIs. Urinalysis results may be helpful to direct initial therapy.

    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.

    The most common pathologies of the seminal tract are persistent hematospermia, seminal vesicle stones, and seminal duct obstruction. Endoscopic diagnostic work-up of the seminal tract is impeded by complex anatomy and lack of technical equipment. To date, there is no standardized endoscopic approach. The purpose of this study was to investigate the applicability and feasibility of a flexible microoptical device for atraumatic endoscopy of the seminal tract in a male human cadaver. The transurethral endoscopic examination was performed on a male cadaver. No premortal interventions or diseases of the genitourinary tract had been reported. The seminal orifice was identified via cystoscopy and accessed by the Seldinger technique using a hydrophilic guidewire and ureteral catheter. Retrograde endoscopic inspection of the distal seminal tract was performed using a miniaturized flexible endoscope. An antegrade endoscopic inspection of the seminal tract was carried out via high scrotal access to the vas deferens. Structures of the seminal tract, such as the ejaculatory duct, seminal vesicles, and distal portion of the ductus deferentes, were visualized using the miniaturized endoscope. Image quality allowed identification of anatomical structures and characterization of tissue properties. The technical limitations we observed involved the system's maneuverability. Initial results of this novel endoscopic approach to the seminal tract using a flexible microoptical system are encouraging. However, considerable anatomical limitations of the targeted organs necessitate further refinements of the technical equipment. This approach might improve diagnostics and treatment of genitourinary diseases. Future surgical techniques may include intraseminal laser therapy or endoocclusion to monitor fertility in men.

  11. Genito-urinary Rhabdomyosarcoma: Overview on SIOP committee trials and results

    Since 1975, 4 rhabdomyosarcoma (RMS) studies have been undertaken by the SIOP (RMS 75, MMT 84, MMT 89 and presently MMT 95) (FLAMANT 1985 -1997). The main goal of theses protocols was to improve the survival of children with RMS while reducing late effects from therapy by restricting the indications for local treatment (surgery and/or radiotherapy) after good response to initial chemotherapy (CT). All theses studies are based on the proven efficacy of initial CT (Vincristine, Dactinomycin, Cyclophosphamide replaced by Ifosfamide) followed by local treatment of residual disease. In case of complete clinical and radiological remission after initial CT, a Mm study (Godzinski 1994) concluded that positive biopsies were rare (5%) and that the local relapse rate remained high even when biopsies apparently confirmed complete remission. subsequently, MMT studies have not placed such emphasis on the value of second look surgery to confirm clinical and radiological evidence of remission. surgery is therefore indicated in case of residual mass after initial CT and should, as a rule, be conservative, anticipating local radiotherapy for residual disease. Genito-urinary RMS account for 24% of all RMS in MMT 84 study and 28% in MMT 89 study. They are classified into two groups, according to slop workshop (RODARY 1989): genito-urinary bladder prostate (GUBP) and genito-urinary non-bladder prostate (GU non BP) including paratesticular RMS in boys and uterine and/or vulvo-vaginal RMS in girls. According to MMT 84 study, tumor site is an important prognostic factor in multivariate analysis as well as T status (according to SIOP UICC- TNM classification) and histology (alveolar versus non alveolar). GU non-BP represents the most favourable site with orbit followed in order by GUBP, head and neck, limbs and other sites

    At the time of writing, radiotherapy is of only minor use in the management of adenocarcinoma of the gastrointestinal tract, for a number of reasons. First, an exploratory laparotomy is generally needed for diagnosis, and if possible the tumour is resected or by-passed. Second, radiotherapy planning in the upper abdomen is complicated by the proximity of small bowel, kidneys, and spinal cord. Third, it has been assumed that these tumours cause death largely as a result of distant metastases, so that local radiotherapy, even if effective, would contribute little to survival. The continued interest in radiotherapy for this group of tumours arises out of the poor survival rates following surgery, which have not changed for many years, and the morbidity associated with their resection. It was hoped that the addition of cytotoxic agents to radical surgery would improve survival rates in carcinoma of the stomach and intraperitoneal colon. Despite a large number of well-organised prospective trials, using a variety of cytotoxic drugs, there is so far no evidence that the addition of chemotherapy to radical surgery improves survival for either tumour site. The authors are therefore faced with a group of tumours which are not only common, but commonly fatal and many surgeons would accept that a new approach using modern radiotherapy techniques may well be justified. There is evidence that this movement is already taking place for carcinoma of the rectum, and the indications for radiotherapy in this condition will be dealt with below. Before considering these it is worth dwelling briefly on recent changes in surgical and radiological practices which, if they fulfil expectations, might allow radiotherapy to be used for carcinoma of the colon, stomach, and pancreas as it is now used for rectal cancer

    Workforce planning is an inexact science. Specialty and Associate Specialist (SAS) doctors are rarely included in workforce analyses. Past studies have shown that SAS doctors are significant contributors to the work in genitourinary (GU) medicine clinics. This survey confirms the large amount of clinical work undertaken by SAS doctors. It appears that 51% of SAS doctors in GU plan to retire in the next 15 years and it is uncertain what effect the 2008 SAS contract will have on SAS recruitment. This information should be taken into consideration in future GUM workforce planning.

    Full Text Available Abstract Mycobacterium tuberculosis infection in renal transplant recipients is associated with significant morbidity and mortality. Genitourinary tuberculosis is a less frequent presentation and a high level of suspicion is needed to avoid treatment delay. Management is challenging due to the interaction of calcineurin inhibitors with antituberculous medications and the known side effects of these drugs, with higher prevalence in this population. The authors present a case of a renal transplant recipient with urinary and constitutional symptoms whom is diagnosed with tuberculosis after a prostatic biopsy in an already disseminated stage and develops hepatotoxicity to antituberculous therapy.

    The application of radionuclide studies in nephrology, urology, and gynecology has reached a measurable degree of maturity in recent years. However, the utilization of these techniques continues to be less frequent than the clinical advantages would seem to warrant, probably because of the complexities of renal physiology. This complexity has been resulted in the availability of large number of agents for renal studies. It is the functional nature of nuclear medicine studies that provides their tremendous potential for use in evaluation of the kidney, where the pathology of which is so often related to functional derangements rather than to anatomic problems. A familiarity with various measures of renal function and with the effects of these parameters on the handling of the commonly used radiopharmaceuticals is essential to the appropriate use of radionuclide studies. The types of studies commonly used include renal perfusion studies, renal imaging solely for anatomic information, and renal imaging combined with an estimate of renal function. Radionuclide techniques serve a complementary role to radiography, ultrasonography, and computed tomography in the morphologic diagnosis of renal diseases. Urethral abnormalities, bladder diverticula, and minimal distal urethral reflux are better demonstrated with radiographic than nuclear technique, but radionuclide cystography can be helpful for follow-up evaluations. Radionuclide testicular imaging is extremely useful in the differential diagnosis of testicular torsion

    Prune belly syndrome (PBS), megacystis-microcolon-intestinal hypoperistalsis (MMIH), and omphalocele-exstrophy of the bladder-imperforate anus-spine abnormalities complex (OEIS) are rare congenital malformations of the newborn that lead to incomplete formation of the gastrointestinal and genitourinary tract systems. To date, incomplete mesodermal development is identified as the cause for all these complex genetic syndromes even if the etiology is still unknown. We present an original case sharing characteristics common to PBS, MMIH, and OEIS complex, without a clear inclination toward any particular one. This case hints toward a common pathway in the creation of the 3 syndromes. We hypothesize that they are a spectrum of malformations based on the time frame when the mesoderm fails to create a normal interaction between infraumbilical mesoderm, urorectal septum, lumbosacral somites in the formation of the abdominal wall and the genitourinary and lower gastrointestinal tracts.

    The ectodermal dysplasia and cleft lip/palate (EEC) syndrome describes the association of ectrodactyly, ectodermal dysplasia and orofacial clefting. As with many autosomal dominant disorders, there is variability in expression and not all of these three core features are present in every individual with the condition. Moreover, there may be additional associated features, which are under-recognized. One of these is the presence of genitourinary anomalies, some of which cause significant morbidity. This report details a further two patients with EEC syndrome and genitourinary involvement, including flaccid megacystis with detrusor muscle failure, bilateral hydronephrosis and megaureter, requiring significant renal and urological involvement during their childhood. We go on to review the literature on the diagnosis and management of genitourinary malformations in EEC syndrome.

Methods: Cross-sectional study of 1068 medical records of patients treated between April/2008 and August/2014. A total of 115 cases suggestive of genitourinary anomalies were selected, regardless of age. A standardized clinical protocol was used, as well as karyotype, hormone levels and genitourinary ultrasound for basic evaluation. Laparoscopy, gonadal biopsy and molecular studies were performed in specific cases. Patients with genitourinary malformations were classified as genitourinary anomalies (GUA, whereas the others, as Disorders of Sex Differentiation (DSD. Chi-square, Fisher and Kruskal–Wallis tests were used for statistical analysis and comparison between groups. Results: 80 subjects met the inclusion criteria, 91% with DSD and 9% with isolated/syndromic GUA. The age was younger in the GUA group (p<0.02, but these groups did not differ regarding external and internal genitalia, as well as karyotype. Karyotype 46,XY was verified in 55% and chromosomal aberrations in 17.5% of cases. Ambiguous genitalia occurred in 45%, predominantly in 46,XX patients (p<0.006. Disorders of Gonadal Differentiation accounted for 25% and congenital adrenal hyperplasia, for 17.5% of the sample. Consanguinity occurred in 16%, recurrence in 12%, lack of birth certificate in 20% and interrupted follow-up in 31% of cases. Conclusions: Patients with DSD predominated. Ambiguous genitalia and abnormal sexual differentiation were more frequent among infants and prepubertal individuals. Congenital adrenal hyperplasia was the most prevalent nosology. Younger patients were more common in the GUA group. Abandonment and lower frequency of birth certificate occurred in patients with ambiguous or malformed genitalia. These characteristics corroborate the literature and show the biopsychosocial impact of genitourinary anomalies.

    Genital ureaplasmas are considered opportunistic pathogens of human genitourinary tract involved in adverse pregnancy sequelae and infertility. While association of Ureaplasma urealyticum with urogenital tract infections is well established, the role of Ureaplasma parvum in these infections is still insufficient. In the study, we compared how often cervicovaginal colonization with U. parvum is associated with the presence of these microorganisms in the upper genitourinary tract of fertile and infertile women. We used PCR assay to determine the prevalence of U. parvum and U. urealyticum in pairs of specimens, i.e., vaginal swabs and Douglas' pouch fluid samples from consecutive 40 women with no symptoms of genital tract infection. In total, 19 (47.5 %) of the 40 samples were positive for ureaplasmas. U. parvum was simultaneously detected in pairs of samples in five (55.5 %) of the nine (47.4 %) women positive in PCR assay. As many as 5 (18.5 %) of the 27 infertile women and 1 (7.7 %) of the 13 fertile women showed infection of the upper genital tract with U. parvum. The results of the study demonstrated that colonization of the lower genital tract with U. parvum can produce asymptomatic infection of the upper reproductive system in women. These findings also imply that U. parvum may be present in the upper genital tract at the time of conception and might be involved in adverse pregnancy outcomes.

    To assess safety and efficacy of a fractional CO2 laser therapy for the treatment of genitourinary syndrome of menopause (GSM) with follow-up to 1 year posttreatment. Women presenting with GSM and meeting inclusion criterion were enrolled. Visual Analog Scales were used to grade vaginal pain, burning, itching, dryness, dyspareunia, and dysuria. Dilators were used to rate vaginal elasticity at baseline and at each follow-up visit. Before each treatment and at follow-up, Vaginal Health Index scoring and Female Sexual Function Index questionnaires were completed. Women received three vaginal laser treatments spaced 6 weeks apart. Participant satisfaction was measured on 5-point Likert scales (1 = very dissatisfied, 5 = very satisfied). Of 30 women (mean age 58.6 ± 8.8 years), three were lost to follow-up at 3 months and six at 1 year. None were discontinued or withdrew due to an adverse event. Average improvement in Visual Analog Scale scores for all symptom categories was statistically significant at 3 months and remained so through 1 year, except dysuria. Differences between data at 3 months and 1 year were not statistically significant, indicating persistence of positive outcomes. Average overall improvement in pain was 1.9 (±3.4), burning 1.9 (±3.1), itching 1.4 (±1.9), dryness 5.9 (±2.8), dyspareunia 4.9 (±3.3), and dysuria 0.9 (±3.1). Improvement in average Vaginal Health Index and Female Sexual Function Index scores was also statistically significant (P < 0.0001). Of 19 women undergoing dilator examination at 1 year, 18 (94.8%) were comfortable with the same or larger dilator size. Twenty-two of 24 women (92%) were satisfied or extremely satisfied with the treatment at 1 year. Based on study data up to 1 year, the fractional CO2 laser may be an effective and safe treatment for women suffering from symptoms of GSM, although additional studies with larger populations and placebo control is needed to confirm these results.

    A study was conducted in the Dermatology cum Genitourinary Clinic, Hospital Sultanah Aminah Johor Bahru to determine a local population's knowledge of HIV and their sexual behaviour in relation to it. A total of 231 men and 217 women were interviewed. The sexual culture seen is one of relatively late age of first sexual intercourse, low level of partner change and low level of condom use. Men reported a higher involvement in risk behaviour. Nearly all the respondents (95.8%) have heard of HIV/AIDS but had incorrect perceptions of its mode of transmission and its associations with risk groups. This study enable us to gain background information about our patients sexual behaviour and HIV knowledge. There is a need to continue HIV education to improve our public's HIV knowledge and the results of this study provides a baseline against which future educational interventions can be gauged.

    For almost the last two decades, interleukin-2 and interferon-alpha have been the only systemic treatment options available for metastatic renal cell carcinoma. However, in recent years, five new targeted therapies namely sunitinib, sorafenib, temsirolimus, everolimus and bevacizumab have demonstrated clinical activity in these patients. With the availability of new targeted agents that are active in this disease, there is a need to continuously update the treatment algorithm of the disease. Due to the important advances obtained, the Spanish Oncology Genitourinary Group (SOGUG) has considered it would be useful to review the current status of the disease, including the genetic and molecular biology factors involved, the current predicting models for development of metastases as well as the role of surgery, radiotherapy and systemic therapies in the early- or late management of the disease. Based on this previous work, a treatment algorithm was developed.

    Medical imaging of the 3 most common genitourinary (GU) cancers-prostate adenocarcinoma, renal cell carcinoma, and urothelial carcinoma of the bladder-has evolved significantly during the last decades. The most commonly used imaging modalities for the diagnosis, staging, and follow-up of GU cancers are computed tomography, magnetic resonance imaging (MRI), and positron emission tomography (PET). Multiplanar multidetector computed tomography and multiparametric MRI with diffusion-weighted imaging are the main imaging modalities for renal cell carcinoma and urothelial carcinoma, and although multiparametric MRI is rapidly becoming the main imaging tool in the evaluation of prostate adenocarcinoma, biopsy is still required for diagnosis. Functional and molecular imaging using 18-fluorodeoxyglucose-PET and sodium fluoride-PET are essential for the diagnosis, and especially follow-up, of metastatic GU tumors. This review provides an overview of the latest advances in the imaging of these 3 major GU cancers. Published by Elsevier Inc.

    2010-01-01

    Full Text Available Background : Automated, high-speed, high-resolution whole slide imaging (WSI robots are becoming increasingly robust and capable. This technology has started to have a significant impact on pathology practice in various aspects including resident education. To be sufficient and adequate, training in pathology requires gaining broad exposure to various diagnostic patterns through teaching sets, which are traditionally composed of glass slides. Methods: A teaching set of over 295 glass slides has been used for resident training at the Division of Genitourinary Pathology, Department of Pathology, University of Pittsburgh Medical Center. Whole slide images were prepared from these slides using an Aperio ScanScope CS scanner. These images and case-related information were uploaded on a web-based digital teaching model. Results: The web site is available at: https://www.secure.opi.upmc.edu/genitourinary/index.cfm. Once logged in, users can view the list of cases, or search cases with or without diagnoses shown. Each case can be accessed through an option button, where the clinical history, gross findings are initially shown. Whole slide images can be accessed through the links on the page, which allows users to make diagnoses on their own. More information including final diagnosis will display when the diagnosis-button is clicked. Conclusion: The web-based digital study set provides additional educational benefits to using glass slides. Residents or other users can remotely access whole slide images and related information at their convenience. Searching and sorting functions and self-testing mode allow a more targeted study. It would also prepare residents with competence to work with whole slide images. Further, the model can be expanded to include pre-rotation and post-rotation exams, and/or a virtual rotation system, which may potentially make standardization of pathology resident training possible in the future.

    Molecular imaging (MI) entails the visualisation, characterisation, and measurement of biologic processes at the molecular and cellular levels in humans and other living systems. Translating this technology to interventions in real-time enables interventional MI/image-guided surgery, for example, by providing better detection of tumours and their dimensions. To summarise and critically analyse the available evidence on image-guided surgery for genitourinary (GU) oncologic diseases. A comprehensive literature review was performed using PubMed and the Thomson Reuters Web of Science. In the free-text protocol, the following terms were applied: molecular imaging, genitourinary oncologic surgery, surgical navigation, image-guided surgery, and augmented reality. Review articles, editorials, commentaries, and letters to the editor were included if deemed to contain relevant information. We selected 79 articles according to the search strategy based on the Preferred Reporting Items for Systematic Reviews and Meta-analysis criteria and the IDEAL method. MI techniques included optical imaging and fluorescent techniques, the augmented reality (AR) navigation system, magnetic resonance imaging spectroscopy, positron emission tomography, and single-photon emission computed tomography. Experimental studies on the AR navigation system were restricted to the detection and therapy of adrenal and renal malignancies and in the relatively infrequent cases of prostate cancer, whereas fluorescence techniques and optical imaging presented a wide application of intraoperative GU oncologic surgery. In most cases, image-guided surgery was shown to improve the surgical resectability of tumours. Based on the evidence to date, image-guided surgery has promise in the near future for multiple GU malignancies. Further optimisation of targeted imaging agents, along with the integration of imaging modalities, is necessary to further enhance intraoperative GU oncologic surgery. Copyright © 2013

    We describe the epidemiological features of adult genitourinary injuries related to consumer products and determined the patient cohorts, products and situations associated with increased genitourinary injury risk. The National Electronic Injury Surveillance System, a data set validated to provide a probability sample of injury related emergency department presentations in the United States, was analyzed to characterize genitourinary injuries from 2002 to 2010. We analyzed 3,545 observations to derive national estimates. An estimated 142,144 adults (95% CI 115,324-168,964) presented to American emergency departments with genitourinary injuries from 2002 to 2010. Of the injuries 69% occurred in men. A large majority of injuries involved the external genitalia. The most common categories of products involved were sporting items in 30.2% of cases, clothing articles in 9.4% and furniture in 9.2%. The highest prevalence of injury was at ages 18 to 28 years (37.5%), which was most often related to sports equipment, such as bicycles. Older cohorts (age greater than 65 years) more commonly sustained injuries during falls and often in the bathroom during use of a shower or tub. Of all patients 88% were evaluated and treated in the emergency department without inpatient admission, although the admission rate increased with increasing patient age. Acute genitourinary injury is often associated with common consumer items and with identifiable high risk cohorts, products and situations. Consumers, practitioners and safety champions can use our epidemiological data to prioritize and develop strategies aimed at the prevention, limitation and informed treatment of such injuries.

    Urinary tract infection is the most common genitourinary disease in children so about 40% of the children with urinary tract infection suffering from reflux that caused some consequences such as pyelonephritis and kidney parenchymal injury. This research was conducted to compare the timing of voiding cystourethrogram (VCUG) in children with urinary tract infection in first week and after the first week of urinary tract infection. This research is a case-control study that both case and control groups include 208 children from 1 month to 12 years old with the complain of urinary tract infection. In case group, the VCUG was performed at the first week of infection and in control group, the VCUG was performed after the first week of infection. complication such as dysuria was observed in two-thirds of children who VCUG was performed during first week after urinary tract infection. Parents stress in case group was more than the other (P=0.015). For overall, the incidence of reflux in case and control groups was 49.5% and 50%, respectively. The mean of reflux grading in right kidney in case group was lower than control group resulting in significant differences between two groups. According to higher grade of stress in parents and complications due to VCUG at the first week of urinary tract infection, it is suggested that VCUG be conducted on selective patients in the hospital at the first week of urinary tract infection and during hospitalization.

    Prune belly syndrome (PBS) extra-genitourinary (extra-GU) manifestations are serious comorbidities beyond the genitourinary (GU) anomalies of this disease. We hypothesized an underestimation of the reported frequency and understated impact on quality of life (QOL) of extra-GU comorbidities in PBS survivors beyond the newborn period. To assess this, the frequencies of extra-GU manifestations of PBS in a contemporary cohort of living patients were compared to compiled frequencies from published literature. Second, the impact of extra-GU PBS manifestations on patient/family QOL was assessed via a non-validated open-ended survey. From 2010 to 2013, PBS survivors were prospectively recruited locally or at three PBS Network National Conventions. The family/subject was asked to complete a detailed PBS questionnaire, non-validated QOL survey, and provide medical records for review. Clinical data were extracted from medical records for local patients. The frequencies of extra-GU manifestations were compared between the contemporary, living cohort and a published literature cohort derived from PubMed. Seven of 706 published studies met criteria for frequencies tabulation of extra-GU PBS manifestations. This largest reported living PBS patient cohort (n = 65) was 99% male with mean age 10 years (1 month-45 years). The living PBS cohort had a statistically significantly higher incidence of gastrointestinal (63%), orthopedic (65%), and cardiopulmonary (49%) diagnoses compared to the compiled published cohort (n = 204). Eleven PBS males and 32 family members completed the QOL survey. Of these, 47% listed at least one non-GU problem (i.e. lung disease, skeletal problems, constipation) as negatively affecting their QOL; 42% listed at least one GU problem (i.e. self-catheterization, recurrent UTIs) as negatively affecting their QOL; 56% reported musculoskeletal surgery and 21% reported gastrointestinal surgery/medication as positively impacting their QOL.

    Full Text Available OBJECTIVE: To investigate changes in nonspecific genitourinary discomfort or pain (GUDP before and after holmium laser enucleation of prostate (HoLEP. GUDP associated with lower urinary tract symptoms (LUTS is a common complaint among benign prostatic hyperplasia (BPH patients, but very little is known about this clinical entity. METHODS: From February 2010 to August 2011, 100 HoLEP patients with complete clinical data at a single institution were enrolled in the study to analyze the degree of GUDP with a visual analog scale (VAS from 0 to 10 points at baseline and at 3 and 6 months postoperatively, and to investigate any relationships between GUDP and urodynamics, uroflowmetry, and scores from the International Prostate Symptom Score (IPSS questionnaire. RESULTS: Fifty-six patients had LUTS only, while the remaining 44 had both LUTS and GUDP. Pain was located in the suprapubic (42.0%, perineal/penile (33.0%, back (17.0%, and perianal (8.0% regions. During the post-operative period, at six months, the VAS, IPSS, peak flow rate and post-void residual volume had improved significantly in 44 GUDP patients (p<0.010. GUDP had completely resolved in 40 (90.9% patients and had decreased in four (9.1% patients, while seven (12.5% patients developed GUDP with voiding in the urethral and perineal areas by the third month postoperatively. When compared to patients with complete resolution, those with persistent GUDP were found to have a significantly higher preoperative presence of bladder outlet obstruction (BOO as an independent risk factor (OR 6.173, 95% CI 1.132-1.323. CONCLUSION: Both GUDP and LUTS improved significantly after HoLEP. Patients with significant preoperative BOO tended to have persistent GUDP after surgery.

    The demographic characteristics, risk behaviourand prevalence of other sexually transmitted diseases (STDs) were determined in 132 HIV-infected individuals seen in a Dermatology cum Genitourinary Clinic, Hospital Sultanah Aminah Johor Bahru. Sixty-one (46.2%) were Malays, 37.9% Chinese, 10.6% Indians and 5.3% were of other ethnic groups. The male to female ratio was 4.5:1. Most of the patients (82.5%) were between 20 to 40 years-old. Seventy (53.0%) were single, 34.1% were married and 7.5% were divorcees. The majority of them (97.7%) were heterosexual. Fifty seven (53.3%) of our male patients patronised commercial workers. Eighty-one (61.8%) were not intravenous drug users (IVDU). Of the 50 IVDUs, 24 had multiple sexual exposures. Fifty-three (48.2%) of the 109 patients screened for STDs had one or more other STDs. Thirty-four patients (31.9%) reported one STD in the past and 3.6% reported two STDs in the past. Fifty-six patients (42.4%) had developed AIDS. Thirteen had passed away. The main mode of transmission of HIV infection in this population is through heterosexual intercourse and the prevalence of STDs is high. These findings indicate a need to advocate responsible sexual behaviour and to detect as well as treat STDs early to prevent the sexual transmission of HIV.

    Purpose: To assess the impact of pretreatment prostate volume on the development of severe acute genitourinary toxicity in patients undergoing intensity-modulated radiation therapy (IMRT) for prostate cancer. Methods and Materials: Between 2004 and 2007, a consecutive sample of 214 patients who underwent IMRT (75.6 Gy) for prostate cancer at two referral centers was analyzed. Prostate volumes were obtained from computed tomography scans taken during treatment simulation. Genitourinary toxicity was defined using the National Cancer Institute Common Terminology Criteria for Adverse Events Version 3.0 guidelines. Acute toxicity was defined as any toxicity originating within 90 days of the completion of radiation therapy. Patients were characterized as having a small or large prostate depending on whether their prostate volume was less than or greater than 50 cm 3 , respectively. Genitourinary toxicity was compared in these groups using the chi-square or Fisher's exact test, as appropriate. Bivariate and multivariate logistic regression analysis was performed to further assess the impact of prostate volume on severe (Grade 3) acute genitourinary toxicity. Results: Patients with large prostates (>50 cm 3 ) had a higher rate of acute Grade 3 genitourinary toxicity (p = .02). Prostate volume was predictive of the likelihood of developing acute Grade 3 genitourinary toxicity on bivariate (p = .004) and multivariate (p = .006) logistic regression. Every 27.0 cm 3 increase in prostate volume doubled the likelihood of acute Grade 3 genitourinary toxicity. Conclusions: Patients with larger prostates are at higher risk for the development of severe acute genitourinary toxicity when treated with IMRT for prostate cancer.

    Laser tissue welding in genitourinary reconstructive surgery has been shown in animal models to decrease operative time, improve healing, and decrease postoperative fistula formation when compared with conventional suture controls. Although the absence of suture material is the ultimate goal, this has not been shown to be practical with current technology for larger repairs. Therefore, suture-assisted laser tissue welding will likely be performed. This study sought to determine the optimal suture to be used during laser welding. The integrity of various organic and synthetic sutures exposed to laser irradiation were analyzed. Sutures studied included gut, clear Vicryl, clear polydioxanone suture (PDS), and violet PDS. Sutures were irradiated with a potassium titanyl phosphate (KTP)-532 laser or an 808-nm diode laser with and without the addition of a light-absorbing chromophore (fluorescein or indocyanine green, respectively). A remote temperature-sensing device obtained real-time surface temperatures during lasing. The average temperature, time, and total energy at break point were recorded. Overall, gut suture achieved significantly higher temperatures and withstood higher average energy delivery at break point with both the KTP-532 and the 808-nm diode lasers compared with all other groups (P welding appears to be between 60 degrees and 80 degrees C. Gut suture offers the greatest margin of error for KTP and 808-nm diode laser welding with or without the use of a chromophore.

    Problem Gestational genitourinary infections are associated with life-long disabilities, but it is unknown if neonatal inflammation is involved. Method Mothers of 914 infants born before 28th gestation week reported cervical/vaginal infection (CVI), and/or urine/bladder/kidney infection (UTI), or neither. Inflammation proteins measured in baby’s blood on postnatal days 1, 7 and 14 were considered elevated if in the top quartile for gestational age. Logistic regression models adjusting for potential confounders assessed odds ratios. Results Compared to neither UTI/CVI, mothers with CVI were more likely to have infants with elevated CRP, SAA, MPO, IL-1β, IL-6, IL-6R, TNF-α, RANTES, ICAM-3, E-selectin and VEGF-R2 on day 1; those with UTI were more likely to have infants with elevated MPO, IL-6R, TNF-R1, TNF-R2, and RANTES on day 7. Placental anaerobes and genital micoplasma were more common in pregnancies with CVI. Conclusion Gestational UTI/CVI should be targeted for preventing systemic inflammation in the very preterm newborn. PMID:25164433

    Specialty trainees in genitourinary medicine (GUM) are required to attain competencies described in the GUM higher specialty training curriculum by the end of their training, but learning opportunities available may conflict with service delivery needs. In response to poor feedback on trainee satisfaction surveys, a four-year modular training programme was developed to achieve a curriculum competencies-based approach to training. We evaluated the clinical opportunities of the new programme to determine: (1) Whether opportunity cost of training to service delivery is justifiable; (2) Which competencies are inadequately addressed by direct clinical opportunities alone and (3) Trainee satisfaction. Local faculty and trainees assessed the 'usefulness' of the new modular programme to meet each curriculum competence. The annual General Medical Council (GMC) national training survey assessed trainee satisfaction. The clinical opportunities provided by the modular training programme were sufficiently useful for attaining many competencies. Trainee satisfaction as captured by the GMC survey improved from two reds pre- to nine greens post-intervention on a background of rising clinical activity in the department. The curriculum competencies-based approach to training offers an objective way to balance training with service provision and led to an improvement in GMC survey satisfaction.

    The Pan-Asian REVIVE survey aimed to examine women's experiences with genitourinary syndrome of menopause (GSM) and their interactions with health-care professionals (HCPs). Self-completed surveys were administered face-to-face to 5992 women (aged 45-75 years) in Indonesia, Malaysia, Singapore, Taiwan, and Thailand. Of 638 postmenopausal women with GSM symptoms, only 35% were aware of the GSM condition, most of whom first heard of GSM through their physician (32%). The most common symptoms were vaginal dryness (57%) and irritation (43%). GSM had the greatest impact on sexual enjoyment (65%) and intimacy (61%). Only 25% had discussed their GSM symptoms with a HCP, and such discussions were mostly patient-initiated (64%) rather than HCP-initiated (24%). Only 21% had been clinically diagnosed with GSM and only 24% had ever used treatment for their symptoms. Three-quarters of those who had used treatment for GSM had discussed their symptoms with a HCP compared to only 9% of those who were treatment-naïve. GSM is underdiagnosed and undertreated in Asia. As discussion of GSM with HCPs appears to be a factor influencing women's awareness and treatment status, a more active role by HCPs to facilitate early discussions on GSM and its treatment options is needed.

    Radiological imaging is paramount for defining the genitourinary fistulae commonly associated with anorectal malformations prior to definitive surgery. The imaging options are resource-limited in many parts of the world. Nonfluoroscopic pressure colostography after colostomy is a cheap method for the evaluation of anorectal malformations. To describe our experience with nonfluoroscopic pressure colostography in the evaluation of anorectal malformations in boys. The study included 12 boys with anorectal malformation who had colostomy and nonfluoroscopic pressure-augmented colostography with water-soluble contrast medium between January 2006 and December 2007. Patient ages ranged from 2 days to 1 year. The types of genitourinary fistula were rectovesical (7.7%) and rectourethral (92.3%). Oblique radiographs were of diagnostic value in all patients. The types of anorectal malformations were high, intermediate and low in 75%, 8.3% and 16.7%, respectively. Short-segment urethral constriction was a common feature of rectourethral fistula (75%, n=9). Our experience has shown that genitourinary fistulae associated with anorectal malformations can be demonstrated reliably by nonfluoroscopic pressure colostography with two oblique radiographs, providing an option in resource-poor settings where fluoroscopic equipment is scarce.

    Full Text Available Lower urinary tract obstruction (LUTO which is most commonly caused by posterior urethral valves or urethral atresia, is often associated with high perinatal mortality and morbidity and long-term childhood renal dysfunction or even renal failure. LUTO is an uncommon clinical entity that can be diagnosed by ultrasonographic examination and is particularly presented by enlarged bladder, hydronephrosis, hydroureter and oligohydramnios. Despite being a rare pathology of the genitourinary tract, detection rates of it is higher than other congenital abnormalities with ultrasonography. Moreover, ultrasonography has become the most widely used diagnostic tool in the diagnosis of LUTO. Pulmonary hypoplasia resulting from severe oligohydramnios is the most common cause of death. Bladder drainage has a critical role on perinatal survival in fetuses with LUTO especially in those predicted to have a poor prognosis. Further interventions and observations of renal therapies may be required in childhood.

    Traffic accidents are the most frequent cause of genitourinary injuries (GUI). Kidney injuries after trauma have been well described. However, there exists a paucity of data on other traumatic GUI after traffic accidents. The objective of this study was to analyze the frequency and type of all GUI, by user category, after traffic accidents. Patient cases were extracted from the trauma registry of the French department of Rhone from 1996 to 2013. We assessed the urogenital injuries presented by each of road user's categories. Severity injuries were coded with the Abbreviated Injury Scale and the Injury Severity Score. Kidney trauma was mapped with the classification of the American Association for the Surgery of Trauma. Multivariate prediction models were used for analysis of data. Of 162,690 victims, 963 presented with GUI (0.59%). 47% were motorcyclists, 22% were in a car, 18% on bicycles, and 9% were pedestrians. The most common organ injury was kidney (41%) followed by testicular (23%). Among the 208 motorists with a GUI, kidney (70%), bladder (10%), and adrenal gland (9%) were the most frequent lesions. Among the 453 motorcyclist victims with GUI, kidney (35%) and testicular (38%) traumas were the most frequent and 62% of injuries involved external genitalia. There were 175 cyclists with GUI, 70% of injuries involved external genitalia; penile traumas (23%) were the most frequent. In total, there were 395 kidney injuries, most being low grade. According to the American Association for the Surgery of Trauma kidney injuries were grade I, 59%; grade II, 11%; grade III, 16%; grade IV, 9%; grade V, 3%; and indeterminate, 2%. GUI is an infrequent trauma after traffic accidents, with kidneys being the most commonly injured. Physicians must maintain a high awareness for external genitalia injuries in motorcyclists and cyclists. Prognostic and epidemiologic study, level III.

    To describe epidemiologic features of sports-related genitourinary (GU) injuries and determine patient cohorts and particular sporting activities associated with increased GU injury risk. The National Electronic Injury Surveillance System, a data set validated to provide a probability sample of injury-related US emergency department (ED) presentations, was analyzed to characterize GU injuries between 2002 and 2010. A total of 13,851 observations were analyzed to derive national estimates. Between 2002 and 2010, an estimated 137,525 individuals (95% confidence interval, 104,490-170,620) presented to US EDs with GU injuries sustained during sporting activities. Nearly three-quarters of injuries occurred in the pediatric population. The most common product involved was a bicycle, representing approximately one-third of injuries in both adult and pediatric populations. Injuries related to team sports such as football, baseball or softball, basketball, and soccer were also common, particularly among boys where they represented a combined third of all injuries. Eighty-nine percent of all patients were evaluated and treated in the ED without inpatient admission. The large majority of injuries involved the external genitalia (60%), and significant injuries of paired GU organs (kidneys and testicles) requiring inpatient admission were rare (8.5%). Sports-related GU injuries are most commonly sustained during the use of a bicycle. However, there are other associated activities with identifiable high-risk cohorts, products, and situations. Consumers, practitioners, and injury-prevention experts can use our epidemiologic data to prioritize and develop strategies aimed at the prevention and limitation of such injuries, particularly when counseling at-risk cohorts, such as those with solitary kidneys or testicles.

    Gestational genitourinary infections, which have been associated with neurodevelopmental impairments among infants born near term, have not been studied among very preterm infants. The mothers of 989 infants born before 28 weeks of gestation were interviewed about urine, bladder, or kidney infections (UTIs) and cervical or vaginal infections (CVIs) during pregnancy, as well as other exposures and characteristics, and their charts were reviewed for the Extremely Low Gestational Age Newborns (ELGAN) Study (2002-2004). At 2 years of age, these infants underwent a neurodevelopmental assessment. Generalized estimating equation logistic regression models of developmental adversities were used to adjust for potential confounders. Infants born to women who reported a UTI were less likely than were others to have a very low Mental Development Index (adjusted odds ratio = 0.5; 95% confidence interval: 0.3, 0.8), whereas infants born to women who reported a CVI were more likely than others to have a low Psychomotor Development Index (adjusted odds ratio = 1.7; 95% confidence interval: 1.04, 2.7). In this high-risk sample, maternal gestational CVI, but not UTI, was associated with a higher risk of impaired motor development at 2 years of age. The apparent protective effect of UTI might be spurious, reflect confounding due to untreated asymptomatic bacteriuria among women who were not given a diagnosis of UTI, or reflect preconditioning. © The Author 2015.

    Background: Non-contrast thin-section helical CT has gained acceptance for the diagnosis of urinary tract calculi in adults, but experience with the technique in children is limited. Purpose: To evaluate the utility of non-contrast thin section helical CT for the diagnosis of urinary tract calculi in children. Materials and methods: Radiology databases at three pediatric institutions were searched to identify all pediatric patients evaluated by ''renal stone'' protocol CT scans (no oral or intravenous contrast, scans covering the entire urinary tract obtained in helical mode with narrow collimation (< 5 mm)). CT scans were reviewed for the primary finding of urinary tract calculi, for secondary signs of acute urinary tract obstruction and for evidence of alternative diagnoses. Medical records were reviewed to determine clinical presentation and to confirm the eventual diagnosis. Results: One hundred thirty-seven scans of 113 children (mean age: 11.2 years) were studied. Thirty-eight of 94 examinations (40%) performed on 82 children for acute pain and/or hematuria showed ureteral calculi. Alternative diagnoses were suggested by CT on 16 scans (17%). Twenty-eight scans were performed on 10 asymptomatic children with known calculus disease confirming renal stone burden on 21 scans (75%) and persistent ureteral calculi on 6 scans (21%). Upper tract calculi were demonstrated on 10 of 15 scans (67%) performed to evaluate for calculi in patients with known non-calculus genitourinary tract abnormalities. Conclusions: Non-contrast thin section helical CT is a useful method to diagnose urinary tract calculi in children. Radiation dose in this retrospective study may exceed the lowest possible radiation dose for diagnostic accuracy. Further research is needed to optimize CT imaging parameters, while maintaining diagnostic accuracy and minimizing radiation dose. (orig.)

  14. Manifestations of Immune Privilege in the Human Reproductive Tract

    2013-02-01

    Full Text Available Like other mucosal surfaces (e.g., the gastrointestinal tract, the respiratory tract, the human female reproductive tract acts as an initial barrier to foreign antigens. In this role, the epithelial surface and subepithelial immune cells must balance protection against pathogenic insults against harmful inflammatory reactions and acceptance of particular foreign antigens. Two common examples of these acceptable foreign antigens are the fetal allograft and human semen/sperm. Both are purposely deposited into the female genital tract and appropriate immunologic response to these non-self antigens is essential to the survival of the species. In light of the weight of this task, it is not surprising that multiple, redundant and overlapping mechanisms are involved. For instance, cells at the immunologic interface between self (female reproductive tract epithelium and non-self (placental trophoblast cells or human sperm express glycosylation patterns that mimic those on many metastatic cancer cells and successful pathogens. The cytokine/chemokine milieu at this interface is altered through endocrine and immunologic mechanisms to favor tolerance of non-self. The foreign cells themselves also play an integral role in their own immunologic acceptance, since sperm and placental trophoblast cells are unusual and unique in their antigen presenting molecule expression patterns. Here, we will discuss these and other mechanisms that allow the human female reproductive tract to perform this delicate and indispensible balancing act.

    Full Text Available Abstract Background Infection plays a role in the pathogenesis of many human malignancies. Whether prostate cancer (PCa - an important health issue in the aging male population in the Western world - belongs to these conditions has been a matter of research since the 1970 s. Persistent serum antibodies are a proof of present or past infection. The aim of this study was to compare serum antibodies against genitourinary infectious agents between PCa patients and controls with benign prostate hyperplasia (BPH. We hypothesized that elevated serum antibody levels or higher seroprevalence in PCa patients would suggest an association of genitourinary infection in patient history and elevated PCa risk. Methods A total of 434 males who had undergone open prostate surgery in a single institution were included in the study: 329 PCa patients and 105 controls with BPH. The subjects' serum samples were analysed by means of enzyme-linked immunosorbent assay, complement fixation test and indirect immunofluorescence for the presence of antibodies against common genitourinary infectious agents: human papillomavirus (HPV 6, 11, 16, 18, 31 and 33, herpes simplex virus (HSV 1 and 2, human cytomegalovirus (CMV, Chlamydia trachomatis, Mycoplasma hominis, Ureaplasma urealyticum, Neisseria gonorrhoeae and Treponema pallidum. Antibody seroprevalence and mean serum antibody levels were compared between cases and controls. Tumour grade and stage were correlated with serological findings. Results PCa patients were more likely to harbour antibodies against Ureaplasma urealyticum (odds ratio (OR 2.06; 95% confidence interval (CI 1.08-4.28. Men with BPH were more often seropositive for HPV 18 and Chlamydia trachomatis (OR 0.23; 95% CI 0.09-0.61 and OR 0.45; 95% CI 0.21-0.99, respectively and had higher mean serum CMV antibody levels than PCa patients (p = 0.0004. Among PCa patients, antibodies against HPV 6 were associated with a higher Gleason score (p = 0.0305. Conclusions

    Objective: To survey radiation oncology practice in the utilization of hormonal and radiation therapy in the primary, adjuvant and salvage treatment of localized prostate cancer. Materials and methods: Genitourinary radiation oncologists practicing in Ontario were invited to participate in a practice survey examining staging, hormonal and radiation management, and radiation technique for a variety of common clinical scenarios. Background demographic information was collected on all respondents. The survey consisted of three cases relating to the hormonal/radiation management of low-, intermediate-, and high-risk prostate cancer as well as two adjuvant and one salvage post-prostatectomy scenarios. The survey response rate was 70% (26/37). Results: Clinicians were more likely to utilize laboratory and imaging studies for staging as the risk categorization increased. Low-risk disease was managed with radiation alone in 26/26 (70 Gy in 65%, 74-79.8 Gy in 35%). Intermediate-risk disease was managed with radiation (70 Gy in 46%, 74-79.8 Gy in 54%) with neoadjuvant hormones in 58%. All respondents managed high-risk disease with adjuvant hormones in addition to radiation therapy (70-71 Gy in 85%, and 76 Gy in 15%). In the pT3a, margin negative (PSA undetectable) scenario, most individuals would not recommend adjuvant radiation (73%). If margins were positive, 30% would still not recommend adjuvant radiation. In the salvage scenario (slowly rising PSA 4 years post-prostatectomy for pT2a close margin disease), all respondents would manage with radiation therapy. Hormones were not routinely recommended in the initial management of the adjuvant and salvage scenarios. Radiation doses utilized for both adjuvant and salvage treatment ranged from 60-70 Gy (median 66 Gy). Conclusions: General agreement exists for the management of low- and high-risk disease and in the post-prostatectomy salvage setting. Use of dose-escalation and neoadjuvant hormones in the intermediate

    Full Text Available At present not only is the site of fertilization in ticks still unknown but it is also unclear as to how this mystery can be solved. Signs of fertilization can be observed throughout the female genital tract and these can be clues for the elucidation of the unsolved questions relating to ticks fertilization. In Boophilus microplus (Canestrini, 1887 the most important signs are the following: the final eversion of the acrosomal canal in females ready for oviposition; the presence of small tubules, resembling the subplasmalemal process of the spermatozoon between the oviduct cells; budding nuclei throughout the female genital tract; and the two Feulgen and DAPI positive areas in the oocyte at vitelogenesis. These morphological characteristics suggest that fertilization takes place in the internal cylinder which extends from the uterus to the ovary itself.Até o momento, não só o lugar da fertilização em carrapatos é desconhecido, mas também não é claro como este mistério possa ser esclarecido. Sinais de fertilização podem ser observados ao longo do trato genital feminino e estes podem ser pistas para a elucidação das questões relacionadas à fertilização em ácaros. Em Boophilus microplus (Canestrini, 1887, os sinais mais importantes são os seguintes: a eversão final do canal acrossômico em fêmeas prestes à oviposição; a presença de pequenos túbulos assemelhando-se a processos subplasmalêmicos dos espermatozóides entre as células do oviduto; brotamentos nucleares ao longo do trato genital feminino e as duas áreas Feulgen e DAPI positivas nos ovócitos em processo de vitelogênese. Estas características morfológicas sugerem que a fertilização ocorra no cilindro interno, o qual se estende desde o útero até o ovário inclusive.

    Acute urinary tract infection (UTI) is an important cause of morbidity in children and may be complicated by congenital urinary tract abnormalities of a functional or anatomic nature which, predispose to recurrent UTI's that in turn may lead to renal failure and hypertension. Early radiologic and ultrasonographic investigations may reveal these anatomic anomalies in particular because the urinary tract, specifically in children, is not readily accessible to adequate clinical examinations Excretory urography (EU) has been considered as the 'gold standard' of upper urinary tract visualization, while the voiding cystourethrogram (VCUG) was thought to be the preferential method of imaging of the lower urinary tract. Recently, major technical advances have altered this commonly accepted diagnostic workup. Although ultrasonography, radio-nuclide scanning and urodynamics have become important contributors to the understanding of pathophysiology of UTI's their value and place in assessment of the sequence of imaging has not been comprehensively studied. This thesis deals about the optimization of the choice and the order of the different imaging techniques used in the evaluation of children, younger than six year with UTI.

    BACKGROUND: Computed tomography urography (CTU) is used widely in the work-up of patients with symptoms of urinary tract lesions. Preoperative knowledge of whether a tumor is invasive or non-invasive is important for the choice of surgery. So far there are no studies about the distinction...... of invasive and non-invasive tumors in ureter and renal pelvis based on the enhancement measured with Hounsfield Units. PURPOSE: To examine the value of CTU using split-bolus technique to distinguish non-invasive from invasive urothelial carcinomas in the upper urinary tract. MATERIAL AND METHODS: Patients...... obtained at CTU could distinguish between invasive and non-invasive lesions. No patients had a CTU within the last year before the examination that resulted in surgery. CONCLUSION: A split-bolus CTU cannot distinguish between invasive and non-invasive urothelial tumors in the upper urinary tract...

  8. Immune Aspects of Female Infertility

    Directory of Open Access Journals (Sweden)

    Andrea Brazdova

    2016-05-01

    Full Text Available Immune infertility, in terms of reproductive failure, has become a serious health issue involving approximately 1 out of 5 couples at reproductive age. Semen that is defined as a complex fluid containing sperm, cellular vesicles and other cells and components, could sensitize the female genital tract. The immune rejection of male semen in the female reproductive tract is explained as the failure of natural tolerance leading to local and/or systemic immune response. Present active immune mechanism may induce high levels of anti-seminal/sperm antibodies. It has already been proven that iso-immunization is associated with infertility. Comprehensive studies with regards to the identification of antibody-targets and the determination of specific antibody class contribute to the development of effective immuno-therapy and, on the other hand, potential immuno-contraception, and then of course to complex patient diagnosis. This review summarizes the aspects of female immune infertility.

    The multilocus sequence typing (MLST) scheme of Ureaplasma based on four housekeeping genes (ftsH, rpL22, valS, and thrS) was described in our previous study; here we introduced an expanded MLST (eMLST) scheme with improved discriminatory power, which was developed by adding two putative virulence genes (ureG and mba-np1) to the original MLST scheme. To evaluate the discriminatory power of eMLST, a total of 14 reference strains of Ureaplasma serovars and 269 clinical strains (134 isolated from symptomatic patients and 135 obtained from asymptomatic persons) were investigated. Our study confirmed that all 14 serotype strains could successfully be differentiated into 14 eMLST STs (eSTs), while some of them could not even be differentiated by the MLST, and a total of 136 eSTs were identified among the clinical isolates we investigated. In addition, phylogenetic analysis indicated that two genetically significantly distant clusters (cluster I and II) were revealed and most clinical isolates were located in cluster I. These findings were in accordance with and further support for the concept of two well-known genetic lineages (Ureaplasma parvum and Ureaplasma urealyticum) in our previous study. Interestingly, although both clusters were associated with clinical manifestation, the sub-group 2 of cluster II had pronounced and adverse effect on patients and might be a potential risk factor for clinical outcomes. In conclusion, the eMLST scheme offers investigators a highly discriminative typing tool that is capable for precise epidemiological investigations and clinical relevance of Ureaplasma.

  2. Preventing urinary tract infections after menopause without antibiotics.

    2017-05-01

    Urinary tract infections (UTIs) are the most common bacterial infections in women, and increase in incidence after the menopause. It is important to uncover underlying abnormalities or modifiable risk factors. Several risk factors for recurrent UTIs have been identified, including the frequency of sexual intercourse, spermicide use and abnormal pelvic anatomy. In postmenopausal women UTIs often accompany the symptoms and signs of the genitourinary syndrome of menopause (GSM). Antimicrobial prophylaxis has been demonstrated to be effective in reducing the risk of recurrent UTIs in women, but this may lead to drug resistance of both the causative microorganisms and the indigenous flora. The increasing prevalence of Escherichia coli (the most prevalent uropathogen) that is resistant to antimicrobial agents has stimulated interest in novel non-antibiotic methods for the prevention of UTIs. Evidence shows that topical estrogens normalize vaginal flora and greatly reduce the risk of UTIs. The use of intravaginal estrogens may be reasonable in postmenopausal women not taking oral estrogens. A number of other strategies have been used to prevent recurrent UTIs: probiotics, cranberry juice and d-mannose have been studied. Oral immunostimulants, vaginal vaccines and bladder instillations with hyaluronic acid and chondroitin sulfate are newer strategies proposed to improve urinary symptoms and quality of life. This review provides an overview of UTIs' prophylaxis without antibiotics, focusing on a practical clinical approach to women with UTIs. Copyright © 2017 Elsevier B.V. All rights reserved.

  3. Probiotic therapy: immunomodulating approach toward urinary tract infection.

    Science.gov (United States)

    Urinary tract infection (UTI) is an extremely common health problem, with an unpredictable history. Members of enterobacteriaceae family such as Escherichia coli, which are normal inhabitants of human intestines, account for the majority of these uncomplicated infections. Rarely, UTI can result from virus or fungus. There is a close correlation between loss of the normal genital microbiota, particularly Lactobacillus species, and an increased incidence of genital and bladder infections. Although antimicrobial agents are generally effective in eradicating these infections, there is a high incidence of recurrence. Use of Lactobacillus species to combat UTI is now giving modern concept of modern genitourinary vaccine with the facts that it not only maintains low pH of the genital area, produces hydrogen peroxide and hinders the growth of E. coli but also activates Toll-like receptor-2 (TLR2), which produces interleukin-10 (IL-10) and myeloid differentiation factor 88 (MyD88). E. coli activates TLR4, which is responsible for the activation of IL-12, extracellular signal-regulated kinase (ERK) and c-Jun N-terminal kinase (JNK). This process downregulates inflammatory reactions caused due to pathogens. Current review covers the probiotics-based TLR therapy and shed some knowledge for the use of Lactobacillus species as probiotics.

    We relied on a population-based case-control study (PROtEuS) to examine a potential association between the presence of histologically confirmed prostate cancer (PCa) and history of genitourinary infections, e.g., prostatitis, urethritis, orchitis and epididymitis. Cases were 1933 men with incident PCa, diagnosed across Montreal hospitals between 2005 and 2009. Population controls were 1994 men from the same residential area and age distribution. In-person interviews collected information about socio-demographic characteristics, lifestyle and medical history, e.g., self-reported history of several genitourinary infections, as well as on PCa screening. Logistic regression analyses tested overall and grade-specific associations, including subgroup analyses with frequent PSA testing. After multivariable adjustment, prostatitis was associated with an increased risk of any PCa (OR 1.81 [1.44-2.27]), but not urethritis (OR 1.05 [0.84-1.30]), orchitis (OR 1.28 [0.92-1.78]) or epididymitis (OR 0.98 [0.57-1.68]). The association between prostatitis and PCa was more pronounced for low-grade PCa (Gleason ≤ 6: OR 2.11 [1.61-2.77]; Gleason ≥ 7: OR 1.59 [1.22-2.07]). Adjusting for frequency of physician visits, PSA testing frequency or restricting analyses to frequently screened subjects did not affect these results. Prostatitis was associated with an increased probability for detecting PCa even after adjustment for frequency of PSA testing and physician visits, but not urethritis, orchitis or epididymitis. These considerations may be helpful in clinical risk stratification of individuals in whom the risk of PCa is pertinent.

    Full Text Available Ahmad K Abou-Foul, Thajunisha M Buhary, Sedki L Gayed Department of Genitourinary Medicine, Royal Blackburn Hospital, East Lancashire Hospitals NHS Trust, Blackburn, UK Introduction: Cases of idiopathic recurrent benign aseptic meningitis were first described by Mollaret. Today, herpes simplex virus (HSV is considered the cause of most cases of Mollaret's meningitis. Case report: A 40-year-old male was referred to our genitourinary medicine clinic with recurrent genital herpetic lesions. He had HSV-2-positive genital ulcers 8 years earlier. One year after the first infection, he developed severe recurrent attacks of headache associated with meningitis symptoms. The results of all radiological and biochemical tests were normal, but the patient reported a correlation between his attacks and genital herpes flare-ups. We diagnosed the patient with Mollaret's meningitis and started him on continuous suppressive acyclovir therapy, which resulted in marked clinical improvement. Discussion: Mollaret's meningitis is a rare form of idiopathic recurrent aseptic meningitis that has a sudden onset, short duration, and spontaneous remission with unpredictable recurrence. We believe that the presence of concurrent or recurrent mucocutaneous herpetic lesions can aid its diagnosis, prior to which, affected patients usually have many unnecessary investigations and treatments. Therefore, detailed sexual history should be sought in all patients with aseptic meningitis, and clinicians should also ask about history of recurrent headaches in all patients with recurrent herpetic anogenital lesions. Continuous suppressive acyclovir therapy may reduce the frequency and severity of attacks and can dramatically improve lifestyle.

    Full Text Available Abstract Introduction Kingella kingae, though part of the normal upper respiratory tract and genitourinary tract, is increasingly being recognized as an important human pathogen. During the past decade, it has emerged as a significant pathogen in the pediatric age group primarily causing bacteremia and osteoarticular infections. Adult infection usually occurs in individuals who are severely immunocompromised and most infections have taken the form of septicemia or septic arthritis. Bacteremia due to K. kingae has been reported as the immediate cause of death in patients with acquired immunodeficiency syndrome. Case presentation We present a microbiologically confirmed urinary tract infection with K. kingae in an immunocompetent 45-year-old adult woman with post-menopausal bleeding and with a history of clots. Her urine was subjected to culture and sensitivity tests. The isolated colonies were identified as K. kingae because of their typical culture characteristics such as long incubation period required for growth, beta-hemolysis, positive oxidase and negative catalase, urease indole, nitrate and citrate tests. Penicillin G disc test was positive. They were sensitive to all conventional antibiotics. Conclusion K. kingae infection is a rare occurrence in immunocompetent adults. Very few cases of microbiologically confirmed infections have been reported so far. The isolation of K. kingae from urine sample has rarely been reported. K. kingae isolates are either missed or misinterpreted by clinical microbiologists. Therefore, K. kingae deserves recognition as a pathogen.

    This study summarized the epidemiology, etiology, and susceptibility of pathogens to antibiotics, and specific characteristics in infants aged less than 4 months diagnosed with urinary tract infection in the past decade in Taiwan. The medical charts of patients aged less than 4 months admitted for urinary tract infection to Kaohsiung Veterans General Hospital between January 2001 and December 2009 were retrospectively reviewed. A total of 132 patients, with male predominance (68.9%), were enrolled. The top three pathogens were similar to those identified in previous studies in Taiwan. The most common pathogen, Escherichia coli (85.3%), was resistant to ampicillin (75.9%), followed by sulfamethoxazole/trimethoprim (31.7%), and cefazolin (28.5%). Dimercaptosuccinic acid (DMSA) renal scan revealed 34.5% positive findings, while the vesicoureteral reflux (VUR) rate was 37.8% by direct radionuclide voiding cystography and/or voiding cysto-urethrography. Positive DMSA findings significantly correlated with VUR (ppediatric population in Taiwan. VUR was the most common genitourinary tract anomaly in this age group. Positive DMSA was well correlated with VUR and higher C-reactive protein level. Copyright © 2012. Published by Elsevier B.V.

    Full Text Available Objective: Ingested foreign bodies in gastrointestinal tract are a common event which can cause serious morbidity and mortality in the children and adult population. For this reason, early diagnosis and treatment are crucial for preventing these life threatening complications. In this study, we aimed to analyze the characteristics of the patients with upper gastrointestinal foreign bodies that were treated in our department. Methods: Patients diagnosed with upper gastrointestinal foreign bodies who were admitted to our hospital between February 2010 and August2013 were evaluated retrospectively. The data regarding their age, gender, clinical profile, type and localization of the esophageal foreign body, performed endoscopic procedure and initial symptoms of the patients were noted and analyzed statistically. Results: Thirty-eight patients with a diagnosis of gastrointestinal foreign body were included in this study. Of these patients, 21 were male and 17 were female. The youngest patient was 17 years old and the oldest patient was 79 years old. Most of the foreign bodies (%55.3 detected in the stomach. Food waste and metallic objects in 21 and 16 patients respectively. The most common complaint was dysphagia (%50. After endoscopic intervention three of the patients were directed to surgery. Conclusion: Early recognition and treatment of gastrointestinal foreign bodies is important as their complications are life threatening. The best method of removal of foreign bodies is controversial. Early management with upper gastrointestinal endoscopy is the most efficient and safe treatment method in current conditions.

    Bicycle riding has become an increasingly popular mode of transportation and exercise, especially among women, and previous studies have demonstrated a relationship between cycling and sexual dysfunction, albeit using non-validated questionnaires. We aimed to explore the relationship between cycling and sexual and urinary dysfunction. Cyclists were recruited to complete a survey through Facebook advertisements and outreach to sporting clubs across 5 English-speaking countries. Swimmers and runners were recruited as a comparison group. Participants were queried using validated questionnaires, including the Female Sexual Function Index, the American Urological Association Symptom Index, and non-validated questions about history of urinary tract infections (UTIs), genital numbness, and genital saddle sores (all self-reported). 3,118 (53.3%) Women completed the survey, comprising 1,053 (34%) non-cyclists, 1,656 (53%) low-intensity cyclists, and 409 (13%) high-intensity cyclists. After adjusting for age, body mass index, hypertension, diabetes, ischemic heart disease, tobacco use, race, marital status, urinary symptoms, and sexual activity, high-intensity cyclists had lower odds of self-reported sexual dysfunction compared to non-cyclists (adjusted odds ratio [aOR] 0.7, P = .02). There were no statistically significant differences in urinary symptoms across groups. Compared to non-cyclists, both low- and high-intensity cyclists had higher odds of reporting a previous UTI (aOR 1.4, P < .001, and aOR 1.4, P = .009, respectively), genital numbness (odds ratio [OR] 6.5, P < .001, and OR 9.1, P < .001, respectively), and saddle sores (OR 6.3, P < .001, and OR 22.7, P < .001, respectively). Women cyclists were more likely to report other genitourinary conditions, including UTIs, genital numbness, and saddle sores. This is the largest study comparing cyclists to other athletes with respect to sexual and urinary function. The study is limited by its cross-sectional design

    Lynch syndrome is responsible for approximately 5% of endometrial cancers and 1% of ovarian cancers. The molecular basis for Lynch syndrome is a heritable functional deficiency in the DNA mismatch repair system, typically due to a germline mutation. This review discusses the rationales and relative merits of current Lynch syndrome screening tests for endometrial and ovarian cancers and provides pathologists with an informed algorithmic approach to Lynch syndrome testing in gynecologic cancers. Pitfalls in test interpretation and strategies to resolve discordant test results are presented. The potential role for next-generation sequencing panels in future screening efforts is discussed.

  19. Diffusion-Weighted Magnetic Resonance Imaging of Urinary Epithelial Cancer with Upper Urinary Tract Obstruction: Preliminary Results

    International Nuclear Information System (INIS)

    Takeuchi, M.; Matsuzaki, K.; Kubo, H.; Nishitani, H.

    2008-01-01

    Background: Various malignant tumors of the body show high signal intensity on diffusion-weighted magnetic resonance imaging (DWI). In the genitourinary region, DWI is expected to have a role in detecting urinary epithelial cancer noninvasively. Purpose: To demonstrate the feasibility of DWI for the diagnosis of urinary epithelial cancer with upper urinary tract obstruction. Material and Methods: Twenty upper urinary tract cancers in 16 patients were evaluated by high-b-value DWI (b=800s/mm2). The signal intensity was visually evaluated, and the apparent diffusion coefficients (ADCs) were measured. Results: All urinary epithelial cancers showed high signal intensity on DWI. The ADC in cancerous lesions was 1.31±0.27 x 10 -3 mm 2 /s, which was significantly lower than that of the lumens of the ureter or renal pelvis (3.32±0.44 x 10 -3 mm 2 /s; P<0.001). Maximum intensity projection images of DWI in combination with static-fluid MR urography provided three-dimensional entire urinary tract imaging with the extension of tumors. Conclusion: DWI is useful in the tumor detection and in evaluating the tumor extension of urinary epithelial cancer in patients with upper urinary tract obstruction

  20. Urinary tract trauma

    From a practical point of view, a woman who has blunt injury to the pelvic area with hematuria from the lower urinary tract, has a contused or ruptured bladder. In a man, such a situation calls for retrograde urethrography to determine if the injury is in the urethra or the bladder because the two organs are investigated differently. In both sexes, such injuries are usually associated with pelvic fractures. Massive bladder displacement and severe hemorrhage should alert one to the need for pelvic angiography to find and embolize the bleeding site within the first 24 hours after injury. For blunt trauma to the upper urinary tract an intravenous urogram with tomography is still the main examination. However, a normal intravenous urogram does not exclude serious injury. Therefore, if signs or symptoms persist, a computerized tomographic (CT) examination should be performed if available. Otherwise, a radionuclide study is advisable. Non-excretion on intravenous urography with tomography calls for selective renal arteriography to delineate the etiology. There can be serious renal trauma in the absence of hematuria, which may occur with renal pedicle injury or avulsion of the ureter. Minor forniceal ruptures may occasionally mask severe posterior renal lacerations.

    We present here a few basic proposals for algorithms and procedures for imaging the paediatric genitourinary tract based on initial discussion at a paediatric uroradiology symposium and proposals of the ESUR Paediatric Uroradiologic Guidelines Subcommittee. These recommendations were developed in the light of new knowledge that might influence existing guidelines. Regional, individual and local flexibility and variability should be preserved in order to make these recommendations applicable throughout Europe. They should help standardize dedicated imaging not only in terms of a quality measure to ensure state-of-the-art patient care, but also in forming a common basis for multi-institutional research. There is an urgent need for these guidelines in order to advance our understanding of the subject and to gain evidence and improve imaging efficacy. Our session worked towards establishing an agreement on imaging indications in common paediatric urological conditions, respecting the ALARA principle, and patient safety and care, and taking into account state of the art knowledge and efficacy aspects. We started the task with a reassessment of (1) imaging in urinary tract infection in infants and children, (2) postnatal imaging in mild-to-moderate neonatal hydronephrosis, (3) how to perform voiding cystourethrography, and (4) procedural recommendations for paediatric urosonography. This list is incomplete, and future recommendations will be developed, discussed and presented at forthcoming meetings. (orig.)

Our session worked towards establishing an agreement on imaging indications in common paediatric urological conditions, respecting the ALARA principle, and patient safety and care, and taking into account state of the art knowledge and efficacy aspects. We started the task with a reassessment of (1) imaging in urinary tract infection in infants and children, (2) postnatal imaging in mild-to-moderate neonatal hydronephrosis, (3) how to perform voiding cystourethrography, and (4) procedural recommendations for paediatric urosonography. This list is incomplete, and future recommendations will be developed, discussed and presented at forthcoming meetings. (orig.)

    To verify the correlation between vocal tract discomfort symptoms and perceived voice handicaps in gospel singers, analyzing possible differences according to gender. 100 gospel singers volunteered, 50 male and 50 female. All participants answered two questionnaires: Vocal Tract Discomfort (VTD) scale and the Modern Singing Handicap Index (MSHI) that investigates the vocal handicap perceived by singers, linking the results of both instruments (psinging. Female gospel singers present higher frequency and intensity of vocal tract discomfort symptoms, as well as higher voice handicap for singing than male gospel singers. The higher the frequency and intensity of the laryngeal symptoms, the higher the vocal handicap will be.

    Full Text Available Background: Urinary tract infection is the most common hospital-acquired infection. Fungal species are unusual causes of urinary tract infection in healthy individuals, but common in the hospital setting or among patients with predisposing diseases and structural abnormalities of the kidney and collecting system. Burn patients are susceptible to nosocomial infections owing to the immunocompromising effects of burn injury, cutaneous and respiratory tract injury, prolonged intensive care unit stays and broad-spectrum antibiotic therapy. Objective: The study population includes adult patients of both genders who presented with different percentages of body burns. Urine sample was collected from each patient at the time of admission and weekly thereafter for 6 weeks and sent for general urine examination and urine culture to test for the possibility of fungal growth. Those who found to develop fungal UTI by urine culture during their hospitalization and had no infection at the time of admission were selected as subjects for our study. Results: 28 (18.6% patients had positive fungal culture during their hospitalization, 11 of them were males and 17 were females, the most common age of presentation was 41-50 years and the mean age ± SD was (44.4 ± 10.7 years. The most common isolated fungi were Candida albicans (64.3%, followed by Candida glabrata (21.4% and Candida tropicalis (7.1%. The majority of patients developed infection within the 2nd and 3rd weeks of hospitalization, however, those who presented with total body surface area burned > 40% developed an earlier infection within the 1st week. Female gender, urethral catheterization and diabetes mellitus were significantly associated with higher risk of infection as the P values were 0.03, 0.005 and 0.004 respectively. Conclusion: Fungal urinary tract infection occurred in 18.6% of burn patients. The most common causative fungi are candida species. Advanced age, female gender, high percentage of

    We performed a prospective cohort parallel observational study on the use of Lactobacillus plantarum P 17630 in the prevention of vaginal infections. Eligible were women with a diagnosis of bacterial vaginosis (Lactobacillus plantarum P 17630 > 100.000.000 UFC one vaginal capsule per day for 6 days, then a capsule per week for 16 weeks. Eligible subjects were enrolled in two parallel cohorts: 85 women using (group A) and 39 not using (group B) Lactobacillus plantarum P 17630. The risk of recurrent infection within 4 months from the study entry, was higher among untreated women: multivariate OR 2.6 (95%CI 0.7-9.4). The modification of presence/intensity or symptoms was significant in both the study groups (p Lactobacillus plantarum P 17630 has been shown to be active in the treatment of bacterial vaginosis and vaginal candidiasis. No data are available on its efficacy in the prevention of recurrent vaginal or urological infection or as a prevention strategy during systemic treatment with antibiotics. What do the results of this study add? This observational study suggests that Lactobacillus plantarum given for 4 months may lower the risk of recurrent infection in women with recurrent vaginal or genitourinary infection or after antibiotic systemic treatment for bacterial respiratory tract infection. The finding, however, is not statistically significant, possibly due to the lower than expected rate of infection observed in our population and consequently the limited power of the study. What are the implications of these findings for clinical practice and/or further research? New studies are needed in order to evaluate in different populations the role of Lactobacillus plantarum in lowering the risk of recurrent infection in a high-risk populations.

    1987-01-01

    Introduction of new methods and enhancement of traditional radiologic methods have greatly influenced the use of imaging to diagnose and treat patients who have urinary tract disease. In the past, plain films of the abdomen and excretory urography were the starting point in the diagnostic imaging process. Today, either computed tomography (CT) or ultrasonography may be requested initially. Choosing the appropriate method has become more complex because of the variety that confronts the physician. If physicians think critically about the selection of patients before requesting an imaging examination, they can improve their use of such examinations. First, the physician must hypothesize a differential diagnosis. Particularly important is the action of linking the use of the diagnostic test to the choice of treatment. The following paragraphs present the most frequently used (or most useful) examinations for the specific diagnostic problem situations that are discussed subsequently

    2014-01-01

    Purpose: To determine the impact of late radiation-induced toxicity on health-related quality of life (HRQoL) among patients with prostate cancer. Patients and methods: The study sample was composed of 227 patients, treated with external beam radiotherapy. Common Terminology Criteria for Adverse Events version 3.0 were used to grade late genitourinary and gastrointestinal toxicity. The European Organization for Research and Treatment of Cancer Quality of life Questionnaire C30 (EORTC QLQ-C30) was used to assess HRQoL at baseline, and 6, 12 and 24 months after completion of radiotherapy. Statistical analysis was performed using a multivariate analysis of variance (MANOVA). Results: Urinary incontinence and rectal discomfort significantly affected HRQoL. The impact of urinary incontinence on HRQoL was most pronounced 6 months after radiotherapy and gradually decreased over time. The impact of rectal discomfort on HRQoL was predominant at 6 months after radiotherapy, decreased at 12 months and increased again 2 years after radiotherapy. No significant impact on HRQoL was observed for any of the other toxicity endpoints, or non-toxicity related factors such as hormonal therapy, radiotherapy technique or age. Conclusion: Urinary incontinence and rectal discomfort have a significant impact on HRQoL. Prevention of these side effects may likely improve quality of life of prostate cancer patients after completion of treatment

    2008-01-01

    Background and purpose: Three randomised trials have demonstrated the benefit of adjuvant post-prostatectomy radiotherapy (PPRT) for high risk patients. Data also documents the effectiveness of salvage radiotherapy following a biochemical relapse post-prostatectomy. The Radiation Oncology Genito-Urinary Group recognised the need to develop consensus guidelines on to whom, when and how to deliver PPRT. Materials and methods: Draft guidelines were developed and refined at a consensus conference in June 2006 attended by 63 delegates where urological, radiotherapy and diagnostic imaging experts spoke on aspects of PPRT. Unresolved issues were further developed by working parties and redistributed until consensus was reached. Results: Central to the recommendations is that patients with positive surgical margins, seminal vesicle invasion and/or extracapsular extension have a high risk of residual local disease and should be informed of the options of either immediate adjuvant radiotherapy or active surveillance with early salvage in the event of biochemical recurrence. Salvage radiotherapy should be instituted at the earliest confirmation of biochemical recurrence. Detailed contouring guidelines have been developed, defining the regions at risk of residual microscopic disease which should be included in the clinical target volume. The recommended doses are 60-64 Gy for adjuvant, and 60-66 Gy for salvage radiotherapy. The role of hormone therapy in conjunction with PPRT is yet to be defined. Conclusions: These consensus guidelines have been developed to give clinical and technical guidance to radiation oncologists and urologists in the management of high risk post-prostatectomy patients

    A female Asian elephant (Elephas maximus) developed vaginal and trunk discharge. Cultures were positive for pan-susceptible Mycobacterium tuberculosis. Isoniazid and pyrazinamide were given rectally and monitored by serum levels. After being trained at 10 mo to accept oral dosing, treatment was changed and rifampin was added. Oral medications were administered for another 10 mo. A year after completion of therapy, the vaginal discharge increased and cultures yielded M. tuberculosis, resistant to isoniazid and rifampin. Treatment with oral ethambutol, pyrazinamide, and enrofloxacin and intramuscular amikacin was initiated. Although followup cultures became negative, adverse reactions to medications precluded treatment completion. Due to public health concerns related to multidrug resistant M. tuberculosis (MDR-TB), the elephant was euthanized. Postmortem smears from the lung, peribronchial, and abdominal lymph nodes yielded acid-fast bacteria, although cultures were negative. This case highlights important considerations in the treatment of M. tuberculosis in animals and the need for a consistent approach to diagnosis, treatment, and follow-up.

    2016-06-01

    Full Text Available Abstract Complicated urinary tract infections (C-UTIs are those associated with structural or functional genitourinary abnormalities or with conditions that impair the host defence mechanisms, leading to an increased risk of acquiring infection or failing therapy. C-UTIs occur in patients with risk factors such as neurogenic dysfunction, bladder outlet obstruction, obstructive uropathy, bladder catheterisation, urologic instrumentation or indwelling stent, urinary tract post-surgical modifications, chemotherapy- or radiation-induced damage, renal impairment, diabetes and immunodeficiency. Multidetector CT and MRI allow comprehensive investigation of C-UTIs and systemic infection from an unknown source. Based upon personal experience at a tertiary care hospital focused on the treatment of infectious illnesses, this pictorial essay reviews with examples the clinical features and cross-sectional imaging findings of C-UTIs affecting the lower urinary tract and male genital organs. The disorders presented include acute infectious cystitis, bladder mural abscesses, infections of the prostate and seminal vesicles, acute urethritis and related perineal abscesses, funiculitis, epididymo-orchitis and scrotal abscesses. Emphasis is placed on the possible differential diagnoses of lower C-UTIs. The aim is to provide radiologists greater familiarity with these potentially severe disorders which frequently require intensive in-hospital antibiotic therapy, percutaneous drainage or surgery. Teaching Points • Complicated urinary tract infections occur in patients with structural or functional risk factors. • CT and MRI comprehensively investigate complicated urinary infections and sepsis from unknown sources. • Infections of the urinary bladder, prostate, seminal vesicles, urethra and scrotum are presented. • Emphasis is placed on differential diagnoses of complicated lower urogenital infections. • Unsuspected urinary infections may be detected on CT

    Full Text Available Pyriform sinus fistula is a rare clinical entity and the precise origin remains controversial. The fistula is discovered among patients with acute suppurative thyroiditis or deep neck infection of the left side of the neck and is usually located in the left pyriform sinus. To the best of our knowledge, only a single tract has been reported to be responsible for pyriform sinus fistula infection. We present a case of a 13-year-old female patient with a pyriform sinus fistula that caused a deep infection of the left side of the neck and showed double-tract involvement discovered during surgical resection of the entire fistula. Both tracts arose around the pyriform sinus and terminated at the upper portion of the left lobe of the thyroid.

    Foreign bodies in the biliary tree are rare causes of obstructive jaundice. Food bezoars are infrequent as well. They can cause biliary obstruction after biliary tract interventions, or in the presence of biliary-bowel fistula or duodenum diverticulum. Food bezoars usually pass the gastrointestinal tract without any symptoms, but they can cause abdominal pain and obstructive jaundice in the case of biliary tract obstruction. Endoscopic retrograde cholangio-pancreatography has the major role in the diagnosis and the treatment of the disease. Authors summarize the medical history of a 91-year-old female patient, who developed vomiting and right subcostal pain due to the presence of tomato peel within the ductus choledochus.

    Full Text Available The spectrum of causative agents of nonspecific infections of the women urogenital tracts is studied. It is established that the typical etiological agents of the vaginosis are yeast-like fungi Candida albicans (35.7 % and Escherichia coli (30.2 %, and the clinical isolates of E. coli (47.3 % and Proteus mirabilis (15.8 % are usual for vulvovaginitis. The frequency of detection of the causative agents of inflammatory genito-urinary diseases in women of different age groups varies: strains of E. coli are often found in patients of 1–12 years (47.3 % and in women of 43–66 years old (36.0 %, but C. albicans – in patients of 18–42 years (39.0 %. High levels of the resistance to penicilline, tetracycline and fluoroquinolone antibiotics in selected clinical isolates of opportunistic microorganisms are determined.

    One of the most important factors implicated in preterm birth (PTB) is acute genitourinary tract infection. The bacteria causing chronic periodontal inflammation include Gram-negative rods and anaerobes similar to those found in women with bacterial vaginosis. The aim of this prospective study is to investigate the relationship between oral and vaginal microflora and preterm low birth weight. Real-time polymerase chain reaction was used to detect both the presence and level of six periodontitis-related species: Aggregatibacter actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), Tannerella forsythia (Tf), Treponema denticola (Td), Fusobacterium nucleatum ssp(Fn), and Prevotella intermedia (Pi) for both oral samples of subgingival plaque and cervical samples, obtained from 80 patients, during gynaecological examinations. The more representative oral pathogen (less than 60 percent) species in oral samples of preterm and term group were Tf, Td, and Fn. 24.4 percent of pregnant women presented periodontal pathogens in vaginal swab; the most representative species with a percentage over 0.1 percent of total bacteria in genital tract of preterm group were Tf, Td, and Piwith a positive correlation (less than 0.5). The presence of the bacterium T. denticolain the vagina, regardless of the amount, adversely affects preterm delivery.

    To compare the periodical incidence rates of genitourinary (GU) and gastrointestinal (GI) toxicity in patients who underwent prostate low-dose-rate brachytherapy between the monotherapy group (seed implantation alone) and the boost group (in combination with external beam radiation therapy (EBRT)). A total of 218 patients with a median follow-up of 42.5 months were enrolled. The patients were divided into 2 groups by treatment modality, namely, the monotherapy group (155 patients) and the boost group (63 patients). The periodical incidence rates of GU and GI toxicity were separately evaluated and compared between the monotherapy group and the boost group using the National Cancer Institute - Common Terminology Criteria for Adverse Events, version 3.0. To elucidate an independent factor among clinical and postdosimetric parameters to predict grade 2 or higher GU and GI toxicity in the acute and late phases, univariate and multivariate logistic regression analyses were carried out. Of all patients, 78.0% showed acute GU toxicity, and 7.8% showed acute GI toxicity, while 63.8% showed late GU toxicity, and 21.1% showed late GI toxicity. The incidence rates of late GU and GI toxicity were significantly higher in the boost group. Multivariate analysis showed that the International Prostate Symptom Score (IPSS) before seed implantation was a significant parameter to predict acute GU toxicity, while there were no significant predictive parameters for acute GI toxicity. On the other hand, combination with EBRT was a significant predictive parameter for late GU toxicity, and rectal volume (mL) receiving 100% of the prescribed dose (R100) was a significant predictive parameter for late GI toxicity. The boost group showed higher incidence rates of both GU and GI toxicity. Higher IPSS before seed implantation, combination with EBRT and a higher R100 were significant predictors for acute GU, late GU and late GI toxicity

    All patients with urine culture-confirmed genitourinary tuberculosis (GUTB) diagnosed between 1995 and 2007 at two medical centers in northern Taiwan were included in this retrospective study. Genotypes of 48 preserved Mycobacterium tuberculosis (MTB) isolates from these patients were determined by spoligotyping and double repetitive element PCR (DRE-PCR) analysis. Among the 64 patients, 38 (59.4%) were male with a mean ±SD age of 60.3 ± 16.1 years old. The overall mortality rate was 26.2%. Poor prognostic factors included age over 65 years (HR = 4.03; 95%; CI: 1.27-12.76), cardiovascular disease (HR = 5.96; 95% CI: 1.98-17.92), receiving steroids (HR = 10.16; 95% CI: 2.27-45.47), not being treated (HR 4.81; 95% CI 1.12-20.67). Spoligotyping and DRE-PCR of the 48 MTB isolates revealed that 20 (41.7%) belonged to the Beijing family and 40 (83.3%) had a clustering pattern. Identification of a Beijing family isolate was not correlated with drug resistance or mortality. Clustering strains were likely to be resistant to isoniazid (OR = 4.71; 95% CI: 1.10 to 23.53). In this study of patients with urine culture-confirmed GUTB, age and coexisting diseases were independently associated with an unfavorable outcome. The Beijing family was the dominant genotype of GUTB isolates, but did not correlate with drug resistance or outcome.

    The 2011 American Academy of Pediatrics (AAP) guidelines address imaging after initial febrile urinary tract infection (UTI) in infants >2 months of age. We sought to determine the frequency of upper urinary tract anomalies (hydronephrosis and vesicoureteral reflux (VUR)) in hospitalized premature infants with UTI. We retrospectively reviewed the electronic medical records of neonatal intensive care unit (NICU) admissions at a tertiary care children's hospital between 1 January 2006 and 31 December 2010. We queried the records for UTI, renal ultrasound (US) and voiding cystourethrogram (VCUG). We identified 3518 unique admissions. UTI occurred in 118 infants (3%). Sixty-nine (60%) had a normal US. Renal dilation was predominantly renal pelvic dilation (12%) and isolated caliectasis (22%). VUR was identified in 15 (14%) infants evaluated with a VCUG. VUR was identified in nine (12%) infants without and in seven (16%) with an abnormality on US. Reflux was identified in 7% of male and 38% of female infants with a UTI. Anatomic abnormalities of the upper urinary tract are uncommon in premature infants with a UTI that occurs during neonatal hospitalization. In concordance with the AAP guidelines, a VCUG may not be required in all NICU infants under age 2 months after a single UTI.

    Full Text Available Urinary tract infections (UTI are frequent conditions in children. Untreated urinary tract infections can lead to serious kidney problems that could threaten the life of the child. Therefore, early detection and treatment of urinary tract infection is important. In older children, urinary tract infections may cause obvious symptoms such as stomach ache and disuria. In infants and young children, UTIs may be harder to detect because of less specific symptoms. Recurrences are common in children with urinary abnormalities such as neurogenic bladder, vesicourethral reflux or those with very poor toilet and hygiene habits. This article reviews the diagnostic approach and presents the current data related to the roles of radiologic imaging, surgical correction and antibiotic prophylaxis of UTIs in children.

    Urinary tract infections can be a significant source of morbidity in the pediatric population. The mainstay of evaluating urinary tract infections in children has been physical examination, urinalysis and culture, and renal and bladder sonography and contrast cystography. However, novel clinical paradigms now consider the importance of various risk factors, such as bacterial virulence and antibiotic-resistance patterns, elimination disorders, and the role of innate immunity and inflammation in determining the likelihood of renal cortical scarring.

    Review of urinary tract infections in adults including etiology, pathogenesis, classification and the most important therapeutic recommendations. Urinary tract infections are still a common clinical problem occurring more often in sexually active women, pregnancy, elderly , after catherization of a urinary bladder and urological surgery as well as in the co-existence of diabetes or nephrolithiasis. Due to the anatomical differences, women suffer more often than men. The main etiological factor is Escherichia coli, even though it plays a lesser role in the complicated infections, than in non-complicated ones. Apart from that, the infections may also be caused by atypical microbes, viruses and fungi. Relapses as well as reinfections are typical features of urinary tract infections and in some cases prolonged infections can spread from lower to upper urinary tract contributing to pyelonephritis, urosepsis or even death. These long-term infections can progress in a hidden, insidious, oligosymptomatic or asymptomatic manner leading to irreversible, progressive deterioration of renal function. They can also mask other diseases such as tuberculosis or neoplasms of the urinary tract, which leads to the delayed diagnosis and treatment. Diagnosis and treatment of urinary tract infections is a complex problem, often requiring specialized procedures as well as hospitalization. The choice of a therapy is determined by the type of infection, general condition, age and coexisting diseases. Rapid diagnosis and implementation of proper pharmacotherapy may shorten the time of treatment and hospitalization, preventing serious complications and reinfections.

    To determine the frequency and pattern of malignant tumours of the female genital tract among Batswana women. A four-year retrospective histological study of the pattern of female genital tract malignancy in Botswana. University of Botswana and the National Health Laboratory Gaborone, Botswana. The National Health Laboratory is the only public tertiary referral laboratory that provides diagnostic pathology services in the South-Eastern part of Botswana. It is located just adjacent to Princess Marina Hospital, the major tertiary referral hospital in the country. All histologically confirmed diagnoses of female genital tract malignancies from January 1st 2006 to December 31st 2009 were reviewed by two pathologists and diagnoses re-confirmed by taking fresh tissue sections from paraffin embedded archival tissue blocks. The age of patients ranged from 13-96 years with a mean age of 54.5 ± 6.4 years. Cancer of the cervix constituted 80.6%, followed by uterine cancer (10.0%), carcinomas of the vulva (4.5%) and ovary (3.4%) in that order. Ovarian cancers predominated in the younger age group. There was a steady increase in the frequencies of cervical, uterine and ovarian cancers over the 4-year study period with a decline in uterine cancer in the 4th year. Cervical cancer incidence is high among Batswana women and all female genital tract cancers occurred at a relatively early mean age. Therefore the importance of established and accessible screening programs and awareness campaigns need more emphasis than it is being given currently. (au)

    Clearance of tagged heavy metal aerosols (Fe, Hg, Mn, Ba, and U) in female beagles by in vivo counting was assessed. Fecal excretion paralleled lower respiratory tract clearance of Fe. No Fe was found in blood, indicating its biological insolubility. Ultrafiltration tests (an indication of biological solubility) ranked the heavy metals as: Hg, Mn, Fe, and U in order of decreasing solubility. The solubility ratios were remarkably similar to the ratios of inverse biological half-times.

    Full Text Available The present study was motivated by the clinical observation of "laryngeal spasms" during dysfluency in an adult female  stutterer. The flexible fiberoptic nasolaryngoscope was employed in an attempt to assess this phenomenon objectively. Findings from fiberscopic and spectrographic investigations provided evidence for a disturbance in laryngeal behaviour, and in turn served to determine the nature of the treatment programme. Asymmetry of the vocal folds  and partial abductory laryngeal behaviour, reflecting  a conflict between adductory and abductory forces, characterized the dysfluency  in this patient. A subjective evaluation after treatment revealed a reduction in both severity and frequency of stuttering behaviour. Furthermore, fiberscopic examination carried out after treatment revealed an absence of the laryngeal disturbances noted previously. Results are considered in terms of vocal tract dynamics in stuttering and its clinical applicability.

  2. Female infertility

    Infertility, defined as 1 year of unprotected intercourse without conception, is becoming of increasingly important medical concern. Fertility in both the male and the female is at its peak in the twenties. Many couples today have postponed marriage and/or childbearing into their 30s until careers are established, but at that point fertility may be diminished. The current epidemic of venereal disease has been associated with an increasing incidence of tubal scarring. In addition, the use of intrauterine devices (IUDs) and birth control pills for contraception have let to later problems with pelvic inflammatory disease (PID) and ovulation disturbances. The problem of infertility intensifies as the number of babies available for adoption decreases. Therefore, it is estimated that approximately 10-20% of couples will eventually seek medical attention for an infertility-related problem. Fortunately, marked improvements in the results of tubal surgery are concurrently occurring secondary to refinements in microsurgical techniques, and many medical alternatives to induce ovulation are being developed. The male factor causes infertility in 30-40 % of couples, and the female factor is responsible in approximately 50% of couples. No cause is found in 10-20% of couples. This chapter discusses the role of coordinated imaging in the diagnosis and therapy of infertility in the female

    Oncological treatments are associated with toxicities that may decrease compliance to treatment in most genitourinary cancer patients. Supplementation with pharmaceutical-standardized supplement may be a supplementary method to control the side effects after chemo- and radiotherapy and the increased oxidative stress associated to treatments. This registry study evaluated a natural combination of supplements containing curcumin, cordyceps, and astaxanthin (Oncotris™) used as supplementary management in genitourinary cancer patients who had undergone oncological therapy. Patients with genitourinary cancers (prostate or bladder malignancies) who had undergone and completed cancer treatments (radiotherapy, chemotherapy or intravesical immunotherapy with increased oxidative stress and residual symptoms) were recruited in this registry, supplement study. Registry subjects (n = 61) freely decided to follow either a standard management (SM) (control group = 35) or SM plus oral daily supplementation (supplement group = 26). Evaluation of severity of treatment-related residual side effects, blood count test, prostate-specific antigen (PSA) test and plasma free radicals (oxidative stress) were performed at inclusion and at the end of the observational period (6 weeks). Two patients dropped out during the registry. Therefore, the analysis included 59 participants: 26 individuals in the supplementation group and 33 in the control group. In the supplement group, the intensity of signs and symptoms (treatment-related) and residual side effects significantly decreased at 6 weeks: minimal changes were observed in controls. Supplementation with Oncotris™ was associated with a significant improvement in blood cell count and with a decreased level of plasmatic PSA and oxidative stress. Naturally-derived supplements, specifically Oncotris™ (patent pending), could support the body to overcome the treatment-related toxicities - and the relative oxidative stress in cancer patients.

    We assessed risk factors for urinary tract infection in children with prenatal hydronephrosis We identified 376 infants with prenatal hydronephrosis in an institutional database. The occurrence of febrile urinary tract infection in the first 2 years of life was ascertained by chart review. Febrile urinary tract infection was defined as a positive culture from a catheterized urine specimen in a patient with a fever of 38.0C or greater. Multivariate logistic regression was used to assess gender, circumcision status, hydronephrosis grade, vesicoureteral reflux grade and antibiotic prophylaxis as predictors of the risk of urinary tract infection. Included in analysis were 277 males and 99 females. Hydronephrosis was high grade in 128 infants (34.0%) and vesicoureteral reflux was present in 79 (21.0%). Antibiotic prophylaxis was prescribed in 60.4% of patients, preferentially to females vs males (70.7% vs 56.7%), those with high vs low grade hydronephrosis (70.3% vs 55.2%) and those with vs without vesicoureteral reflux (96.2% vs 50.8%). On multivariate analysis there was an association between high grade hydronephrosis and an increased risk of urinary tract infection (adjusted OR 2.40, 95% CI 1.26-4.56). Females (adjusted OR 3.16, 95% CI 0.98-10.19) and uncircumcised males (adjusted OR 3.63, 95% CI 1.18-11.22) were also at higher risk than circumcised males. Antibiotic prophylaxis was not associated with a decreased risk of urinary tract infection (adjusted OR 0.93, 95% CI 0.45-1.94). High grade hydronephrosis, female gender and uncircumcised status in males are independent risk factors for febrile urinary tract infection in infants with prenatal hydronephrosis. Antibiotic prophylaxis did not reduce the risk of urinary tract infection in the study group. Copyright © 2014 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

    Full Text Available Background and ObjectivesMorbidity and mortality of urinary tract infection is common in spite of prescription of effective new antibiotics. Chronic pyelonphritis is one of the important reasons of end stage renal failure. Our study is carried out on 167 children admitted in Fatemi koodacan Hospital due to urinary tract infection. Major goal of this study was determination of epidemiology of urinary tract infection.Methods This study was cross sectional descriptive and sampling method was census. Various Factors such as age, gender, causative pathogen, used antibiotics and required time for getting negative urine culture test were studied. data were collected by means questionnaire.ResultsAccording to the study urinary tract infection was more common in females (74.2% of all cases while in male neonates it is more common than females. Incidence peak of urinary tract infection is seen in children between 1-6 years old. The most common pathogens responsible to urinary tract infection was E. coli and Klebsiella. The most common background disease was vesicoureteral reflux. The most common prescribed antibiotic was ceftriaxone (65%. After 2 days of taking antibiotic the majority of patients (87.7% had negative urine culture.ConclusionIn our study E. coli and Klebsiella are the most common pathogen responsible to urinary tract infection. In our study the frequency of urinary tract infection with Proteus was low (only 1.1% in comparison with other studies. Other epidemiological indices in this study were comparable to previous studies.Keywords: Urinary Tract, Urinary Tract Infections, Children

  9. Female condoms.

    1997-06-01

    Early versions of a female condom were available in the 1920s and 1960s, but they were little used and soon forgotten. It took the arrival of AIDS, and the urgent need for a wider range of female-controlled barrier techniques, to rekindle scientific interest in this method. In the 1980s, three groups in Europe and the USA began development of new female condom designs, comprising 'Femidom (Reality)', the 'Bikini Condom', and 'Women's Choice'. Apart from differences in their physical design, Femidom differs from the others in that it is made of a polyurethane membrane, which has several advantages over latex. Of the three, Femidom is the most advanced in terms of development and clinical testing, and it is the only one to have reached the marketing stage. Laboratory studies and clinical trials suggest that its contraceptive efficacy is similar to that documented for the male condom, though a direct comparison is not possible because no comparative clinical trials have, as yet, been undertaken. Reported 'typical-use' pregnancy rates range from 12.4 to 22.2% at 6 months of use in the USA and Latin America, respectively, while a study in the UK observed a rate of 15% at 12 months. As with all barrier methods, most failures appear to be associated with poor compliance or incorrect use. 'Perfect-use' pregnancy rates were substantially lower, indicating that Femidom can be very effective, if used consistently and correctly. Evidence for Femidom's effectiveness to protect against transmission of sexual disease-causing organisms, including HIV, is still very limited and based largely on laboratory studies. Whilst, in theory, the condom should confer reliable protection, its efficacy in clinical use will depend upon correct and consistent use and upon the product's ability to maintain an effective physical barrier throughout penetrative intercourse. In this respect, the results of recent and ongoing clinical studies are expected with much interest. How valuable Femidom will

    Full Text Available Respiratory tract infection during Hajj (pilgrimage to Mecca is a common illness, and it is responsible for most of the hospital admissions. Influenza virus is the leading cause of upper respiratory tract infection during Hajj, and pneumonia can be serious. Taking into account the close contacts among the pilgrims, as well as the crowding, the potential for transmission of M. tuberculosis is expected to be high. These pilgrims can be a source for spreading infection on their return home. Although vaccination program for influenza is implemented, its efficacy is uncertain in this religious season. Future studies should concentrate on prevention and mitigation of these infections.

  11. Australian and New Zealand Faculty of Radiation Oncology Genito-Urinary Group: 2011 consensus guidelines for curative radiotherapy for urothelial carcinoma of the bladder

    Curative radiotherapy, with or without concurrent chemotherapy, is recognized as a standard treatment option for muscle-invasive bladder cancer. It is commonly used for two distinct groups of patients: either for those medically unfit for surgery, or as part of a 'bladder preserving' management plan incorporating the possibility of salvage cystectomy. However, in both situations, the approach to radiotherapy varies widely around the world. The Australian and New Zealand Faculty of Radiation Oncology Genito-Urinary Group recognised a need to develop consistent, evidence-based guidelines for patient selection and radiotherapy technique in the delivery of curative radiotherapy. Following a workshop convened in May 2009, a working party collated opinions and conducted a wide literature appraisal linking each recommendation with the best available evidence. This process was subject to ongoing re-presentation to the Faculty of Radiation Oncology Genito-Urinary Group members prior to final endorsement. These Guidelines include patient selection, radiation target delineation, dose and fractionation schedules, normal tissue constraints and investigational techniques. Particular emphasis is given to the rationale for the target volumes described. These Guidelines provide a consensus-based framework for the delivery of curative radiotherapy for muscle-invasive bladder cancer. Widespread input from radiation oncologists treating bladder cancer ensures that these techniques are feasible in practice. We recommend these Guidelines be adopted widely in order to encourage a uniformly high standard of radiotherapy in this setting, and to allow for better comparison of outcomes.

    To identify risk factors for antibiotic resistance to Escherichia coli (E. coli) in children with urinary tract infections (UTIs) in emergency room and primary care clinics. This is a cross-sectional study of children 0 to 18 years of age reported to have E coli-positive UTIs whose medical and laboratory records were systematically reviewed. Compared with girls, boys were 2.29 times (confidence interval [CI] = 1.30-4.02) more likely to have E coli isolates resistant to ampicillin and 2 times more likely (CI = 1.13-3.62) to have isolates resistant to trimethoprim-sulfamethoxazole (TMP/SMX). Patients with genitourinary abnormalities were 1.57 times more likely to be resistant to ampicillin (CI = 1.03-2.41) and 1.86 times to TMP/SMX (CI = 1.18-2.94). Higher rates of ampicillin and TMP/SMX resistant urinary E coli isolates were observed among boys and children with a history of genitourinary abnormality. Age and recent antibiotic prescription are also potential risk factors for resistance. © The Author(s) 2015.

    2001-01-01

    Urinary tract infections are very common during pregnancy. Escherichia coli is the most common pathogen isolated from pregnant women. Ampicillin should not be used because of its high resistance to Escherichia coli. Pyelonephritis can cause morbidity and can be life-threatening to both mother and fetus. Second and third-generation cephalosporins are recommended for treatment, administered initially intravenously during hospitalization. Cultures and the study of virulence factors of uropathogenic Escherichia coli are recommended for the adequate management of pyelonephritis. The lower genital tract infection associated with pyelonephritis is responsible for the failure of antibiotic treatment. Asymptomatic bacteriuria can evolve into cystitis or pyelonephritis. All pregnant women should be routinely screened for bacteriuria using urine culture, and should be treated with nitrofurantoin, sulfixosazole or first-generation cephalosporins. Recurrent urinary infection should be treated with prophylactic antibiotics. Pregnant women who develop urinary tract infections with group B streptococcal infection should be treated with prophylactic antibiotics during labour to prevent neonatal sepsis. Preterm delivery is frequent. Evidence suggests that infection plays a role in the pathogenesis of preterm labour. Experimental models in pregnant mice support the theory that Escherichia coli propagated by the transplacental route, involving bacterial adhesins, induces preterm delivery, but this has not been demonstrated in humans. Ascending lower genital tract infections are the most probable cause of preterm delivery, but this remains to be proved.

    Danuta Zwolińska

    2016-09-01

    Full Text Available Urinary tract infection is the most frequent bacterial infection in children. Its prevalence in the population younger than 14 years of age has been estimated at 5–10%. Its high recurrence, especially in patients with risk factors, poses a significant problem. The risk factors most common in the group of children ≤3 years are congenital defects blocking the flow of urine to the bladder, whereas in older children they most typically include a tendency for constipation and dysfunction of the lower urinary tract. The clinical picture is variable and depends on the child’s age, immunity status, pathogen virulence and localisation of infection. The mildest form of urinary tract infection is asymptomatic bacteriuria, whereas more severe presentations include acute pyelonephritis, acute focal bacterial nephritis and urosepsis. Prognosis is usually good, but under certain circumstances hypertension, proteinuria and chronic kidney disease may develop. Therefore, early introduced appropriate treatment is essential. According to the Polish Society for Paediatric Nephrology guidelines, asymptomatic bacteriuria does not warrant treatment, whereas febrile patients (>38°C under 24 months old with a suspicion for urinary tract infection must be promptly administered antibiotic therapy, after a urine specimen has been obtained for culture. For many years, urinary tract infection has remained a topic of controversy in terms of therapy duration and administration route. Inpatient treatment of children under 3 months of age is an accepted rule. Acute pyelonephritis necessitates a longer therapy, lasting from 7 to 10 days, whereas the duration of treatment of lower urinary tract infection has been cut down to 3 up to 5 days. Routine prophylactic antimicrobial therapy is not recommended following the initial urinary tract infection episode, yet should be considered in special circumstances. Alternative

    With the goal of better defining the types of bladder dysfunction observed in this population, we present the chief urologic complaints, results of urodynamic studies, and treatments of patients with dysautonomia-related urinary symptoms. All patients with dysautonomia referred to our neurourology clinic between 2005 and 2015 for management of lower urinary tract dysfunction were retrospectively reviewed. Each patient's chief urologic complaint was recorded and used to initially characterize the bladder storage or voiding symptoms. Patient evaluation included history and physical examination, urinalysis, post void bladder ultrasound, and urodynamic studies. Successful treatment modalities that subjectively or objectively improved symptoms were recorded. Of 815 patients with the diagnosis of dysautonomia, 82 (10 %) were referred for evaluation of lower urinary tract dysfunction. Mean age was 47 years (range 12-83) and 84 % were female. The chief complaint was urinary urgency ± incontinence in 61 % and hesitancy in 23 % of patients. Urodynamic findings demonstrated detrusor overactivity ± incontinence in 50 % of patients, although chief complaint did not reliably predict objective findings. Successful objective and subjective treatments were multimodal and typically non-operative. Lower urinary tract dysfunction may develop in at least 10 % of patients with dysautonomia, predominantly females. Bladder storage or voiding complaints do not reliably predict urodynamic findings. Urodynamically, most patients exhibited detrusor overactivity. The majority of patients were successfully managed with medical or physical therapy.

  1. Dosimetry of the respiratory tract

    International Nuclear Information System (INIS)

    Roy, M.

    1996-01-01

    A new dosimetric model of the human respiratory tract has been recently recommended by the International Commission on Radiological Protection, in ICRP Publication 66. This model was intended to update the previous lung model of the Task Group on Lung Dynamics that was adopted by ICRP in Publication 30. With this aim, extensive reviews of the available knowledge were made for anatomy and physiology of the respiratory tract and for deposition, clearance and biological effects of inhaled radionuclides. Finally, expanded dosimetry requirements resulted in a widely different approach from the former model. The main features of the new model are the followings: instead of calculating the average dose to the total mass of blood filled lung, the model takes account of differences in radiosensitivity of the venous respiratory tract tissues. It applies not only to adult workers but also to all members of the population, and provides reference values for children aged 3 months, 1, 5, 10, and 15 years, and adults. Deposition modelling of airborne gases and aerosols associates age dependent breathing rates, airway dimensions and physical activity, to particle size, density and chemical form of inhaled material. Clearance results of competition between mechanical transport clearance and absorption to blood. At each step of the calculation, adjustment guidance is provided to account for use of exact values of particle sizes and specific dissolution rates of inhaled material in order to calculate their own parameter of retention in the airways, and to assess accurately doses to the respiratory tract. Possible influence of smoking, of respiratory tract diseases and of eventual exposure to airborne toxicants is also addressed. (author)

    Urinary tract infections (UTI) are among the most frequent bacterial infections in the community and health care setting. Mostly young and, to some extent, postmenopausal women are affected by recurrent UTI (rUTI) defined as ≥3 UTI/year or ≥2 UTI/half year. In contrast, rUTI is rare in healthy men. On the other hand, rUTI are frequently found in female and male patients with complicating urological factors, e.g. urinary catheters, infection stones. Remediable predisposing factors in uncomplicated rUTI in women are rare. In complicated rUTI the success depends mainly on the possibility to eliminate or at leastimprove the complicating risk factors. Continuous antibiotic prophylaxis or postcoital prophylaxis, if there is close correlation with sexual intercourse, are most effective to prevent rUTI. Nitrofurantoin, trimethoprim (or cotrimoxazole), and fosfomycin trometamol are available as first-line drugs. Oral cephalosporins and quinolones should be restricted to specific indications. Antibiotic prophylaxis reduces the number of uropathogens in the gut and/or vaginal flora and reduces bacterial "fitness". Given the correct indication, the recurrence rate of rUTI can be reduced by about 90%. Due to possible adverse events and the concern of selecting resistant pathogens, according to the guidelines of the European Association of Urology antimicrobial prophylaxis should be considered only after counselling, behavioural modification and non-antimicrobial measures have been attempted. In postmenopausal patients vaginal substitution of oestriol should be started first. Oral or parenteral immunoprophylaxis is another option in patients with rUTI. Other possibilities with varying scientific evidence are prophylaxis with cranberry products, specific plant combinations or probiotics. The prophylaxis of catheter-associated UTI should employ strategies which result in a reduction of frequency and duration of catheter drainage of the urinary tract. The currently available

    2009-09-01

    Full Text Available Primary non-Hodgkin’s lymphomas (NHL of the sinonasal tract are rather uncommon entities. Morphologically and radiographically, sinonasal lymphomas are difficult to distinguish from other malignant neoplasms or non- neoplastic processes. They have a variable presentation from fulminant destructive manifestations to chronic indolent type of disease and may mimic as carcinomas and invasive fungal infection respectively. We report a case of primary NHL involving sinonasal tract in elderly female, which was clinically and radiologically mimicking as sinonasal malignany and was proven as NHL on histological examination and confirmed by immunohistochemistry. A high index of suspicion, appropriate histopathological examination and immunohistochemistry is necessary to differentiate sinonasal lymphomas from other possibilities. Failure to do so may miss the diagnosis and delay appropriate treatment

  6. Urinary tract infections during pregnancy - an updated overview.

    Science.gov (United States)

    Szweda, Hanna; Jóźwik, Marcin

    Urinary tract infections (UTIs) are the most common type of infection during pregnancy, affecting up to 10% of pregnant women. They are also recognized as the second most common ailment of pregnancy, after anemia. Three clinical types of pregnancy-related UTI are distinguished: asymptomatic bacteriuria (ASB), cystitis, and pyelonephritis. A particular form of ASB is the presence of Group B streptococci in the urinary tract of the pregnant woman. All clinical types of UTI may lead to serious maternal and fetal complications. Therefore, unlike in the nonpregnant female patient, all UTIs during pregnancy, including the asymptomatic infection, require treatment. In some patients, antibiotic prophylaxis should also be introduced. In the present work, we collectively summarize current practical recommendations from a number of international bodies and organizations.

    Diagnostic imaging of the reproductive tract in reptiles is used for gender determination, evaluation of breeding status, detection of pathologic changes, and supervising treatment. Whole-body radiographs provide an overview and support detection of mineralized egg shells. Sonography is used to evaluate follicles, nonmineralized eggs, and the salpinx in all reptiles. Computed tomography is able to overcome imaging limitations in chelonian species. This article provides detailed information about the performance of different imaging techniques. Multiple images demonstrate the physiologic appearance of the male and female reproductive tract in various reptile species and pathologic changes. Advantages and disadvantages of radiography, sonography, and computed tomography are described. Copyright © 2016 Elsevier Inc. All rights reserved.

    Ebara, Takeshi; Akimoto, Tetsuo; Kato, Hiroyuki

    2007-01-01

    The purpose of this study was to evaluate late rectal bleeding and genitourinary (GU) morbidity in patients consecutively treated with combined high-dose-rate (HDR) brachytherapy and external beam radiation therapy (EBRT). Data from 80 patients treated consecutively from October 2000 to May 2004 were analyzed. The median age was 69 years old, median follow-up 31 months, ranging from 17-59 months. All patients received endocrine therapy before radiation therapy. The patients were divided into low-, intermediate- and high-risk groups (4/24/52 patients) according to the risk factors defined by T-classification, prostatic specific antigen (PSA) and Gleason score. Fractionation schedules for HDR brachytherapy were prospectively changed, and EBRT was fixed with 3 Gy fractions to 51 Gy. The distribution of fractionation was scheduled as follows; 5 Gy x 5 times in 14 patients, 7 Gy x 3 times in 19 patients, and 9 Gy x 2 times in 47 patients. The rectal bleeding was graded using the toxicity criteria of the Radiation Therapy Oncology Group and European Organization for Research and Treatment of Cancer while the genitourinary morbidities were graded using the toxicity criteria of the Common Terminology Criteria for Adverse Events v.3.0. Grade 2 or worse rectal bleeding developed in 9 patients (11.3%) with the 2-year actuarial probability at 11.2%. Grade 2 and 3 rectal bleeding was recognized in 8 and 1 patients, respectively. Grade 3 morbidity developed in the biopsied sites that were performed in the other hospital. No significant difference was observed in any HDR brachytherapy fractionation schedule. Grade 2 or worse GU morbidities were recognized in 30 patients (37.5%), consisting of 29 Grade 2 patients and 1 Grade 3 patient. Twenty-one patients in Grade 2 morbidity had an increase in the frequency of urination or nocturia, and urethral strictures developed in 3 patients. The 3-year actuarial probability of urethral stricture was 6.0%. One patient experienced Grade 3

    Purpose: Several investigations have revealed that the α/β ratio for prostate cancer is atypically low, and that hypofractionation or high-dose-rate (HDR) brachytherapy regimens using appropriate radiation doses may be expected to yield tumor control and late sequelae rates that are better or at least as favorable as those achieved with conventional radiation therapy. In this setting, we attempted treating localized prostate cancer patients with HDR brachytherapy combined with hypofractionated external beam radiation therapy (EBRT). The purpose of this study was to evaluate the feasibility of using this approach, with special emphasis on the relationship between the severity of acute genitourinary (GU) toxicity and the urethral dose calculated from the dose-volume histogram (DVH) of HDR brachytherapy. Methods and Materials: Between September 2000 and December 2003, 70 patients with localized prostate cancer were treated by iridium-192 HDR brachytherapy combined with hypofractionated EBRT at the Gunma University Hospital. Hypofractionated EBRT was administered in fraction doses of 3 Gy, three times per week; a total dose of 51 Gy was delivered to the prostate gland and the seminal vesicles using the four-field technique. No elective pelvic irradiation was performed. After the completion of EBRT, all the patients additionally received transrectal ultrasonography (TRUS)-guided HDR brachytherapy. The fraction size and the number of fractions in HDR brachytherapy were prospectively changed, whereas the total radiation dose for EBRT was fixed at 51 Gy. The fractionation in HDR brachytherapy was as follows: 5 Gy x 5, 7 Gy x 3, 9 Gy x 2, administered twice per day, although the biologic effective dose (BED) for HDR brachytherapy combined with EBRT, assuming that the α/β ratio is 3, was almost equal to 138 in each fractionation group. The planning target volume was defined as the prostate gland with 5-mm margin all around, and the planning was conducted based on

    Genital tract secretions inhibit Escherichia coli (E. coli) through antimicrobial peptides (AMP) secreted by the host and vaginal microbiota. However, there are limited data against group B Streptococcus (GBS). Group B Streptococcus were incubated with cervico-vaginal lavage (CVL) samples from healthy non-pregnant women (n = 12) or synthetic AMP and monitored for bacterial growth using a turbidimetric approach. E. coli inhibitory activity was determined by a colony-forming unit assay. None of the CVL samples inhibited GBS. The human neutrophil peptide-1 and human defensin 5 inhibited GBS growth by ≥80% at concentrations ≥20 μg/mL and ≥50 μg/mL, respectively, while human beta-defensin 2 and LL-37 did not inhibit at highest concentration tested (100 μg/mL). In contrast, all AMP inhibited E. coli. Antimicrobial peptides may protect against E. coli colonization but have more limited activity against GBS. Future studies will focus on augmenting host defense with specific AMP to prevent genitourinary infection with these pathogenic organisms. © 2015 John Wiley & Sons A/S.

    2005-12-01

    Urinary tract infections, asymptomatic bacteriuria (AB), acute cystitis (AC) and acute pyelonephritis (AP), are favored by the morphological and functional changes involved in pregnancy. AB increases the risk of preterm labor, low birth weight and AP. AB should be detected by uroculture (other methods are not sufficiently effective) and treated early. Approximately 80% of cases are caused by Escherichia coli. The risks and effectiveness of the distinct antibiotic regimens should be evaluated: fosfomycin trometamol in monotherapy or as short course therapy is safe and effective for the treatment of AB and AC. AP is the most frequent cause of hospital admission for medical reasons in pregnant women and can lead to complications in 10% of cases, putting the lives of the mother and fetus at risk. Currently outpatient treatment of AP is recommended in selected cases. Adequate follow-up of pregnant women with urinary tract infections is required due to frequent recurrence.

    Sarcoidosis is a chronic granulomatous disease of unknown aetiology. It can affect any part of the organism, although the lung is the most frequently affected organ. Upper airway involvement is rare, particularly if isolated. Sarcoidosis is a diagnosis of exclusion, established by histological evidence of non-caseating granulomas and the absence of other granulomatous diseases. The authors report a case of a man with sarcoidosis manifesting as a chronic inflammatory stenotic condition of the upper respiratory tract and trachea. PMID:27090537

    This manuscript describes the male genital tract microbiota and the significance of it on the host's and his partner's health. Microbiota exists in male lower genital tract, mostly in urethra and coronal sulcus while high inter-subject variability exists. Differences appear between sexually transmitted disease positive and negative men as well as circumcised and uncircumcised men. Upper genital tract is generally germ-free, except in case of infections. Prostatitis patients have frequently abundant polymicrobial communities in their semen, expressed prostatic secretion and/or post-massage urine. Coryneform bacteria have ambivalent role in male urogenital tract being frequently commensals but sometimes associated with prostatitis and urethritis. Interactions between male and female genital tract microbiota are highly likely yet there are very scarce studies on the couples' genital tract microbiota. Increase of bacterial vaginosis-type microbiota and coliforms are the most typical findings in men while the adverse effect of male genital tract bacteria on in vitro fertilization and pregnancy outcome has also been indicated.

    Full Text Available Background: Although the association of urinary lithiasis and urinary tract malformation is not rare, their management poses challenges. The aim of this study was to evaluate the relationship between urolithiasis and malformations of the urinary system. There were 34 patients (19 males and 15 females with a mean age of 4.8 years (range, 2 months to 14 years. All patients had urinary lithiasis with a urinary tract malformation. Abdominal pain was the most frequent clinical symptom (38%. Urinary infection was found in 7 patients (21% and macroscopic haematuria was present in 10 patients (29%. The most frequent urinary tract malformations were megaureter (8 cases, uretero-pelvic junction obstruction (7 cases and vesico-ureteric reflux (8 cases, but its malformative origin could not be confirmed. Treatment consisted of lithiasis extraction in 32 cases associated with specific treatment of the uropathy in 27 cases. Postoperative outcome was uneventful in all cases. In fact, urinary lithiasis and urinary tract malformation association is not rare. Indeed, 9-34% of urinary lithiasis are noted to be associated with urinary tract malformation. Positive diagnosis relies specifically on kidney ultrasound, intravenous urography, and urethrocystography. Treatment depends on the type of urinary tract malformation, localisation and size of the urinary lithiasis. Conclusion: In conclusion, urinary lithiasis and urinary tract malformation association is a frequent eventuality. Surgical intervention is the usual mode of treatment.

    Singing styles in Musical Theater singing might differ in many ways from Western Classical singing. However, vocal tract adjustments are not understood in detail. Vocal tract shapes of a single professional Music Theater female subject were analyzed concerning different aspects of singing styles using dynamic real-time magnetic resonance imaging technology with a frame rate of 8 fps. The different tasks include register differences, belting, and vibrato strategies. Articulatory differences were found between head register, modal register, and belting. Also, some vibrato strategies ("jazzy" vibrato) do involve vocal tract adjustments, whereas others (classical vibrato) do not. Vocal tract shaping might contribute to the establishment of different singing functions in Musical Theater singing. Copyright © 2014 The Voice Foundation. Published by Elsevier Inc.

    To provide a comprehensive review of urinary tract infections (UTIs) during pregnancy. All aspects of UTIs, including epidemiology, pathogenesis, resistance, clinical features, diagnosis, treatment, and prevention, were reviewed. MEDLINE (1966-August 2003) and Cochrane Library searches were performed using the key search terms urinary tract infection, pyelonephritis, cystitis, asymptomatic bacteriuria, and resistance. All article abstracts were evaluated for relevance. Only articles pertaining to pregnancy were included. The majority of published literature were review articles; the number of original clinical studies was limited. UTIs are the most common bacterial infections during pregnancy. They are characterized by the presence of significant bacteria anywhere along the urinary tract. Pyelonephritis is the most common severe bacterial infection that can lead to perinatal and maternal complications including premature delivery, infants with low birth weight, fetal mortality, preeclampsia, pregnancy-induced hypertension, anemia, thrombocytopenia, and transient renal insufficiency. Enterobacteriaceae account for 90% of UTIs. The common antibiotics used are nitrofurantoin, cefazolin, cephalexin, ceftriaxone, and gentamicin. Therapeutic management of UTIs in pregnancy requires proper diagnostic workup and thorough understanding of antimicrobial agents to optimize maternal outcome, ensure safety to the fetus, and prevent complications that lead to significant morbidity and mortality in both the fetus and the mother.

    Full Text Available The issues of diagnosing and treating urinary tract infections and their role in development of renal injury are being actively discussed by scientists and practicing pediatricians. The article presents the most recent data on etiological factors, pathogenesis and clinical manifestations of this disease. It provides recommendations on diagnosis and management of patients depending on their age. The article presents a discussion of antibacterial therapy course duration and indications for anti-relapse treatment. The study demonstrates that intravenous antibacterial therapy must be launched immediately in neonates in the event of pyretic fever; empirical antibacterial therapy must be launched immediately in older children after diagnosis of the urinary tract infection has been confirmed; subsequently, treatment ought to be corrected depending on the results of a bacteriological trial, sensitivity to antibiotics and effectiveness of the prescribed antibiotic. Along with normalization of urination rhythm and water intake schedule, antibacterial preventive therapy might be considered, if effective, in the event of recurrent nature of the urinary tract infection. 

  1. Comparative mRNA and microRNA expression profiling of three genitourinary cancers reveals common hallmarks and cancer-specific molecular events.

    Xianxin Li

    Full Text Available Genome-wide gene expression profile using deep sequencing technologies can drive the discovery of cancer biomarkers and therapeutic targets. Such efforts are often limited to profiling the expression signature of either mRNA or microRNA (miRNA in a single type of cancer.Here we provided an integrated analysis of the genome-wide mRNA and miRNA expression profiles of three different genitourinary cancers: carcinomas of the bladder, kidney and testis.Our results highlight the general or cancer-specific roles of several genes and miRNAs that may serve as candidate oncogenes or suppressors of tumor development. Further comparative analyses at the systems level revealed that significant aberrations of the cell adhesion process, p53 signaling, calcium signaling, the ECM-receptor and cell cycle pathways, the DNA repair and replication processes and the immune and inflammatory response processes were the common hallmarks of human cancers. Gene sets showing testicular cancer-specific deregulation patterns were mainly implicated in processes related to male reproductive function, and general disruptions of multiple metabolic pathways and processes related to cell migration were the characteristic molecular events for renal and bladder cancer, respectively. Furthermore, we also demonstrated that tumors with the same histological origins and genes with similar functions tended to group together in a clustering analysis. By assessing the correlation between the expression of each miRNA and its targets, we determined that deregulation of 'key' miRNAs may result in the global aberration of one or more pathways or processes as a whole.This systematic analysis deciphered the molecular phenotypes of three genitourinary cancers and investigated their variations at the miRNA level simultaneously. Our results provided a valuable source for future studies and highlighted some promising genes, miRNAs, pathways and processes that may be useful for diagnostic or

    The study of lower genital tract trauma has become important in gynaecological practice. There is paucity of reports on this clinical entity from our settings. The main aim of this study is to document injuries in female lower genital tract in Mid-Western Nepal. Sixty female patients admitted to the hospital with genital tract injuries caused by coitus or accidents were included in the study. Details of the causes of trauma clinical presentations and management were recorded. These injuries were grouped according to etiological factors. This study included 33 (55%) coital injuries and 27 (45%) non- coital injuries. Out of coital injury, 12 cases were criminal assault (rape) in age group of 4 to 18 years. Four unmarried girls had consensual sex. Non-coital injuries were due to fall from height, cattle horn injuries, straddle type of trauma, vulvar haematoma and anorectal injuries. Appropriate surgical intervention can avert morbidity and mortality.

    Urinary tract infection (UTI) is a common bacterial infection in childhood with favourable outcome. However, the recent emergence of UTI caused by multidrug-resistant pathogens, such as carbapenem-resistant Enterobacteriaceae (CRE), has become a great concern worldwide. CRE are mainly responsible for nosocomial infections and community-onset CRE infections in healthy individuals are rare. In this study, we report a series of infants without substantial genitourinary abnormalities that were admitted with community-onset urinary tract infections (UTIs) caused by carbapenem-resistant Klebsiella pneumoniae (CRKP) and we discuss their aetiology. We retrospectively reviewed the medical records of nine infants who presented from community to the paediatric ward with CRKP urinary tract infections, as well as all affected neonates of a concomitant CRKP outbreak that occurred in the neonatal intensive care unit (NICU) in a tertiary hospital (period from April 2009 to July 2012). We further retrieved all culture-proven CRKP infections of any site from 2007 to 2015 in our paediatric department. Over a 33-month period, nine infants, all males, aged 0.9-19.3 (median 4.0) months, were admitted to the Department of Paediatrics with UTI caused by CRKP. Three of them were diagnosed with urinary tract abnormalities but only one had vesicoureteral reflux (VUR), which was a UTI-associated one. History revealed that they had all been hospitalised in the same NICU during a concurrent long-lasting CRKP outbreak for a median of 17 (2-275) days and thereafter presented with CRKP UTI 15 to 207 (median 41) days after NICU discharge. The antibiotic susceptibility and phenotypic characteristics were identical among all isolates in NICU and the paediatric ward. The summary Figure shows a timeline of NICU hospitalisation indicative of its duration and subsequent CRKP UTI of study participants is presented. These cases illustrate that UTI caused by multidrug-resistant pathogens does not

    We characterize the current national patterns of antibiotic resistance of outpatient pediatric urinary tract infection. We examined outpatient urinary isolates from patients younger than 18 years in 2009 using The Surveillance Network®, a database with antibiotic susceptibility results and patient demographic data from 195 United States hospitals. We determined the prevalence and antibiotic resistance patterns for the 6 most common uropathogens, ie Escherichia coli, Proteus mirabilis, Klebsiella, Enterobacter, Pseudomonas aeruginosa and Enterococcus. We compared differences in uropathogen prevalence between males and females using chi-square analysis. We identified 25,418 outpatient urinary isolates. E. coli was the most common uropathogen overall but the prevalence of E. coli was higher among females (83%) than males (50%, p Resistance among E. coli was highest for trimethoprim-sulfamethoxazole (24%) but lower for nitrofurantoin (less than 1%) and cephalothin (15%). Compared to 2002 Surveillance Network data, E. coli resistance rates increased for trimethoprim-sulfamethoxazole (from 23% to 31% in males and from 20% to 23% in females) and ciprofloxacin (from 1% to 10% and from 0.6% to 4%, respectively). E. coli remains the most common pediatric uropathogen. Although widely used, trimethoprim-sulfamethoxazole is a poor empirical choice for pediatric urinary tract infections in many areas due to high resistance rates. First-generation cephalosporins and nitrofurantoin are appropriate narrow-spectrum alternatives given their low resistance rates. Local antibiograms should be used to assist with empirical urinary tract infection treatment. Copyright © 2013 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

    A 13 year female consulted to Heatup Pad's surgery department with a history of pelvic malformations since she was born and complaining about a colostomy done five years ago. On clinical examination an anal fistula was seen as well as perineal organs duplicated including: vulva - four labia, clitoris, vaginal canal, urethra, also double gluteal cleft. Several diagnostic modalities were performed (voiding cystourethrography, urodynamic, renal scan, CT and MRI) having a diagnosis of complete duplication of the hindgut and lower urinary tract, a rare congenital anomaly that has fewer than 50 cases reported in the literature. During hospitalization she underwent successful abdominopelvic surgical Correction.

    We constructed a risk prediction instrument stratifying patients with primary vesicoureteral reflux into groups according to their 2-year probability of breakthrough urinary tract infection. Demographic and clinical information was retrospectively collected in children diagnosed with primary vesicoureteral reflux and followed for 2 years. Bivariate and binary logistic regression analyses were performed to identify factors associated with breakthrough urinary tract infection. The final regression model was used to compute an estimation of the 2-year probability of breakthrough urinary tract infection for each subject. Accuracy of the binary classifier for breakthrough urinary tract infection was evaluated using receiver operator curve analysis. Three distinct risk groups were identified. The model was then validated in a prospective cohort. A total of 252 bivariate analyses showed that high grade (IV or V) vesicoureteral reflux (OR 9.4, 95% CI 3.8-23.5, p urinary tract infection (OR 5.3, 95% CI 1.1-24.7, p = 0.034) and female gender (OR 2.6, 95% CI 0.097-7.11, p urinary tract infection. Subgroup analysis revealed bladder and bowel dysfunction was a significant risk factor more pronounced in low grade (I to III) vesicoureteral reflux (OR 2.8, p = 0.018). The estimation model was applied for prospective validation, which demonstrated predicted vs actual 2-year breakthrough urinary tract infection rates of 19% vs 21%. Stratifying the patients into 3 risk groups based on parameters in the risk model showed 2-year risk for breakthrough urinary tract infection was 8.6%, 26.0% and 62.5% in the low, intermediate and high risk groups, respectively. This proposed risk stratification and probability model allows prediction of 2-year risk of patient breakthrough urinary tract infection to better inform parents of possible outcomes and treatment strategies.

    Full Text Available Urinary tract infections frequently affect pregnant mothers. This problem causes significant morbidity and healthcare expenditure. Three common clinical manifestations of UTIs in pregnancy are: asymptomatic bacteriuria, acute cystitis and acute pyelonephritis. Escherichia coli remains the most frequent organism isolated in UTIs. All pregnant mothers should be screened for UTIs in pregnancy and antibiotics should be commenced without delay. Urine culture and sensitivity is the gold standard in diagnosing UTIs. Without treatment, asymptomatic bacteriuria in pregnancy is associated with preterm delivery, intrauterine growth retardation, low birth weight, maternal hypertension, pre-eclampsia and anaemia. Acute pyelonephritis can lead to maternal sepsis. Recurrent UTIs in pregnancy require prophylactic antibiotic treatment.

    Cystic duplications of the biliary tract are rare anomalies, easily mistaken for choledochal cysts. Surgical drainage is the preferred therapy for choledochal cyst, but cystic duplication necessitates surgical excision as duplications may contain heterotopic gastric mucosa leading to peptic ulceration of the biliary tract. We report a case of biliary tract duplication cyst containing heterotopic alimentary mucosa which had initially been diagnosed and surgically treated as a choledochal cyst.

    Urinary tract infection is the most common type of bacterial infection in kidney transplant procedures, with adverse effects on graft and patient survival. We aimed to evaluate the risk factors of recurrent urinary tract infection in renal transplant recipients and its impact on patient and graft survival. In a cohort of 1019 patients who were transplanted between 2000 and 2010 at Hamed Al-Essa Organ Transplant Center in Kuwait, 86% developed at least 1 episode of urinary tract infection, with only 6.2% of patients having recurrent infections. We compared patients with recurrent urinary tract infections (group 1) with those who had no recurrence (group 2) regarding their risk factors. Patients in group 1 were significantly younger than those in group 2 (34.9 ± 23 vs 42.8 ± 16 y; P urinary tract infections (P infections were significantly more prevalent among group 1 (10.8% vs 3.8%; P = .008). Long-term graft outcome (functioning and failed) were 78.5% and 21.5% in group 1 versus 85.1% and 13.9% in group 2 (P = .18). Patient outcomes (living and deceased donors) were 98.4% and 1.6% in group 1 versus 95.7% and 4.3% in group 2 (P = .187). Adult females, thymoglobulin induction, pretransplant urologic problems, and hepatitis C infection were the risk factors of recurrent urinary tract infection among our renal transplant patients. However, recurrence did not adversely affect graft or patient survival.

    The function of the lower urinary tract is basically storage of urine in the bladder and the at-will periodic evacuation of the stored urine. Urinary incontinence is one of the most common lower urinary tract disorders in adults, but especially in the elderly female. The urethra, its sphincters, and the pelvic floor are key structures in the achievement of continence, but their basic anatomy is little known and, to some extent, still incompletely understood. Because questions with respect to continence arise from human morbidity, but are often investigated in rodent animal models, we present findings in human and rodent anatomy and histology. Differences between males and females in the role that the pelvic floor plays in the maintenance of continence are described. Furthermore, we briefly describe the embryologic origin of ureters, bladder, and urethra, because the developmental origin of structures such as the vesicoureteral junction, the bladder trigone, and the penile urethra are often invoked to explain (clinical) observations. As the human pelvic floor has acquired features in evolution that are typical for a species with bipedal movement, we also compare the pelvic floor of humans with that of rodents to better understand the rodent (or any other quadruped, for that matter) as an experimental model species. The general conclusion is that the "Bauplan" is well conserved, even though its common features are sometimes difficult to discern.

    Improvements in ultrasound technology and the appropriate timing of antenatal ultrasound has led to refined prenatal diagnosis and enhanced accuracy of diagnosis of fetal renal anomalies and makes it possible to treat obstructive and/or refluxing uropathies before the onset of clinical symptoms. The third trimester renal sonography is the most important to detect hydronephrosis amenable to treatment. Classically, the prenatal diagnosis of hydronephrosis, unilateral renal agenesis, or MDKD initiates postnatal investigations, including sonography, voiding cystourethrography (VCUG), and isotopic renography. The exact degree of renal pelvic dilatation that requires full postnatal investigation is still not entirely resolved. Most authors accept the upper limit of 7 mm for the AP diameter of the renal pelvis. The US examination should be performed after the physiological dehydration period, namely 3-5 days after birth, in an urgent case on the 1st day. A meticulous ultrasound examination performed by a physician who is familiar with the renal abnormalities shows the whole extent of underlying pathology. The role of MR urography in the work-up of renal anomalies, particularly of hydronephrosis, is currently being investigated. Due to the close developmental relationship of the urinary and genital tracts, malformations frequently occur in both of these systems. Therefore in all patients, especially in girls with renal anomalies (unilateral renal agenesis, multicystic dysplastic kidney disease), the internal genitalia need to be evaluated. (orig.)

    To determine the prevalence,location, and distribution of sinus tracts in patients referred for endodontic consultation. This cohort study included 1,119 subjects referred for endodontic consultation, 108 of whom presented with sinus tracts. Following clinical and radiographic examination, the diameter of the rarifying osteitis lesion on the radiograph was measured and the path and origin of the sinus tracts determined. Signs and symptoms, tooth site,buccal/lingual location, and diameter were recorded. Data were statistically analyzed using Pearson chi-square test. Sinus tracts originated mainly from maxillary teeth (63.1%); only 38.9% originated from mandibular teeth. Chronic periapical abscess was the most prevalent diagnosed origin (71.0%). Broken restorations were highly associated with the presence of sinus tracts (53.0%). The most frequent site of orifices was buccal(82.4%), followed by lingual or palatal (12.0%). Orifices on the lingual aspect of the gingiva were observed in mandibularmolars. There was an 86.8% correlation between the occurrence of an apically located sinus tract and apical rarifying osteitis(P<.01). Sinus tract in the lingual or palatal aspect of the gingiva is relatively common. Practitioners should look for signs of sinus tract during routine examination

    There is a known association between nonneurogenic lower urinary tract conditions and vesicoureteral reflux. Whether reflux is secondary to the lower urinary tract condition or coincidental is controversial. We determined the rate of reflux resolution in patients with lower urinary tract dysfunction using targeted treatment for the underlying condition. Patients diagnosed and treated for a lower urinary tract condition who had concomitant vesicoureteral reflux at or near the time of diagnosis were included. Patients underwent targeted treatment and antibiotic prophylaxis, and reflux was monitored with voiding cystourethrography or videourodynamics. Vesicoureteral reflux was identified in 58 ureters in 36 females and 5 males with a mean age of 6.2 years. After a mean of 3.1 years of treatment reflux resolved with targeted treatment in 26 of 58 ureters (45%). All of these patients had a history of urinary tract infections before starting targeted treatment. Resolution rates of vesicoureteral reflux were similar for all reflux grades. Resolution or significant improvement of reflux was greater in the ureters of patients with dysfunctional voiding (70%) compared to those with idiopathic detrusor overactivity disorder (38%) or detrusor underutilization (40%). Vesicoureteral reflux associated with lower urinary tract conditions resolved with targeted treatment and antibiotic prophylaxis in 45% of ureters. Unlike the resolution rates reported in patients with reflux without a coexisting lower urinary tract condition, we found that there were no differences in resolution rates among grades I to V reflux in patients with lower urinary tract conditions. Patients with dysfunctional voiding had the most improvement and greatest resolution of reflux. Additionally grade V reflux resolved in some patients.

    A review is presented of the design of radiolabelled test meals for the evaluation of gastrointestinal function, including oesophageal transit, gastro-oesophageal reflux, gastric emptying, enterogastric reflux and transit through the whole bowel. Descriptions of different systems are presented, together with validations of the procedures used. Published methods for assessment of oesophageal transit show a marked degree of consistency, whereas gastric emptying studies employ a wide range of both liquid and solid test meals. Recommendations are made concerning the optimal system for investigation of each part of the gastrointestinal tract, but whichever system is adopted, it is important to employ some validation procedures, and to establish normal ranges in the population under study.

    Urinary tract infections (UTIs) are among the most common bacterial infections in children which can be a source of significant morbidity. For as yet unknown reasons a minority of UTIs in children progress to renal scarring, hypertension and renal insufficiency. Clinical presentation of UTI in children may be nonspecific, and the appropriateness of certain diagnostic tests remains controversial. The diagnostic work-up should be tailored to uncover functional and structural abnormalities such as dysfunctional voiding, vesicoureteral reflux and obstructive uropathy. A more aggressive work-up is recommended for patients at greater risk for pyelonephritis and renal scarring, including infants less than one year of age. Early sequential (intravenous treatment followed by oral antibiotics) antibacterial therapy is recommended to prevent renal scarring. Routine antibiotic prophylaxis is not recommended, it may be used in patients with higher grade reflux, obstructive uropathy or recurring UTI who are at greater risk for subsequent infections and complications.

    In addition to personal observations of 77 patients with one or more metastatic sites in the gastrointestinal tract, the authors reviewed over 1000 similar cases in the literature. The general radiologic aspects of each location (oesophagus, stomach, intestine, colon/rectum) are discussed. The pathophysiology of this type of metastasis explains the radiologic images obtained during barium transit examinations. The lymphatic type of spread observed in the oesophageal region in connection with carcinoma of the breast is the origin of stenosis of the middle third. The haematogenous type of diffusion encountered during melanomas creates intramural or intraluminal radiologic images. Two means of spread can be observed in the stomach. Haematogenous spread can result in frequently multiple and ulcerated nodular submucosal lesions from melanomas and bronchogenic carcinomas; it can also cause a more or less stenotic invasive image, especially in connection with carcinoma of the breast. Dissemination by means of the mesenteric reflections, and in particular around the gastrocolic ligament, explains the spread of a carcinoma of the transverse colon towards the stomach. The most frequent secondary sites in the gastrointestinal tract occur in the small intestine, the majority of these metastases being caused by pelvic tumours. Whether occurring in the small intestine or the colon, the patophysiology is similar: direct invasion by a non-contiguous primary carcinoma along the fascias and mesenteric attachments (more rarely by lymphatic permeation), dissemination by the peritoneal fluid or haematogenuous spread. In the first two types of dissemination cited, the image encountered is often hard to differentiate from radiation-induced lesions. (orig.)

    Background: There are no well-established normal tissue sparing dose–volume histogram (DVH) criteria that limit the risk of urinary toxicity from prostate radiation therapy (RT). The aim of this study was to determine which criteria predict late toxicity among various DVH parameters when contouring the entire solid bladder and its contents versus the bladder wall. The area under the histogram curve (AUHC) was also analyzed. Methods and Materials: From 1993 to 2000, 503 men with prostate cancer received 3-dimensional conformal RT (median follow-up time, 71 months). The whole bladder and the bladder wall were contoured in all patients. The primary endpoint was grade ≥2 genitourinary (GU) toxicity occurring ≥3 months after completion of RT. Cox regressions of time to grade ≥2 toxicity were estimated separately for the entire bladder and bladder wall. Concordance probability estimates (CPE) assessed model discriminative ability. Before training the models, an external random test group of 100 men was set aside for testing. Separate analyses were performed based on the mean age (≤ 68 vs >68 years). Results: Age, pretreatment urinary symptoms, mean dose (entire bladder and bladder wall), and AUHC (entire bladder and bladder wall) were significant (P 68 years. Conclusion: The AUHC method based on bladder wall volumes was superior for predicting late GU toxicity. Age >68 years was associated with late grade ≥2 GU toxicity, which suggests that risk-adapted dose constraints based on age should be explored

    Inflammation of the urethra defined by an excess of polymorphonuclear leukocytes in the absence of sexually transmitted Chlamydia trachomatis and Neisseria gonorrhoeae is called non-chlamydial non-gonococcal urethritis (NCNGU). Although Mycoplasma genitalium is now recognised as causing a sexually transmitted infection, the clinical significance of the other Mollicute species is less clear. This study used specific real-time quantitative polymerase chain reaction assays to detect and quantify four Mollicute species, M. genitalium, M. hominis, Ureaplasma urealyticum and U. parvum, in urine specimens from men with and without NCNGU. A total of 165 urine specimens from male patients attending a genitourinary medicine clinic were eligible for the study, with microscopy-confirmed (≥5 polymorphonuclear leukocytes in urethral swab) NCNGU in 75 (45.5%) and non-confirmed NCNGU in 90 (54.5%). Chi-squared statistical analysis indicated a significantly higher prevalence of U. parvum (17.3% vs. 5.6%; p = 0.03) and M. genitalium (12% vs. 0%; p < 0.001) in NCNGU. In a subset analysis, M. genitalium was also significantly (p = 0.03) higher in men who have sex with men (MSM; 13.5%) compared to non-MSM (3.1%). No significant associations were reported for U. urealyticum and M. hominis In conclusion, this study supports a clinically significant role in NGNCU for both U. parvum and M. genitalium. © The Author(s) 2015.

    As age and sex affect the function of the lower urinary tract, we studied the characteristics of adrenergic and cholinergic receptors in various parts of lower urinary tract smooth muscle of young (6 months) and old (4 1/2-5 years) male and female rabbits. Saturation experiments performed with [3H]prazosin, [3H]yohimbine, [3H]dihydroalprenolol and [3H]quinuclidinyl benzylate in rabbit bladder base, bladder dome and urethra indicate the presence of regional, sex- and age-related differences in the density of alpha-1, alpha-2, and beta adrenergic and muscarinic cholinergic receptors. Alpha-2 adrenergic receptor density is considerably higher in the female than in the male urethra of both age groups, whereas the higher density of beta adrenergic receptors in the female than in the male bladder base is observed only in the younger animals. The density of muscarinic receptors is higher in bladder dome than in bladder base or urethra in young rabbits of both sexes. In the old animals, the density of muscarinic receptors in bladder base increases to the level observed in bladder dome. Inhibition experiments with selective adrenergic agonists and antagonists indicate that the pharmacological profiles of alpha-2 adrenergic receptors in the urethra and beta adrenergic receptors in the bladder dome and bladder base are similar in both sexes and at both ages. Beta-2 adrenergic receptors are shown to be predominant in bladder base and bladder dome of rabbits. Parallel studies in rabbit urethra, adult rat cortex and neonatal rat lung show that the urethral alpha-2 adrenergic receptors are of the alpha-2A subtype

    To evaluate and analyze the pattern of patients with urinary stone diseases admitted to Mekelle Hospital. Between Sept 2003 to Sept 2006, 102 patients with urinary stone disease were admitted to Mekelle Hospital. In this descriptive retrospective audit, case notes were obtained from medical record office and were analyzed for age, sex, localization of the stone disease and the geographic back grounds. Seventy six (74.5%) of the patients were males and 26 (25.5%) were females. There were 102 (13.6%) cases of urinary stone disease admitted to Mekelle Hospital out of 750 total admissions for urological disease for intervention in the surgical ward during the study period. There were 76 (74.5%) males and 26 (25.5%) females and the sex ratio was (M: F: 2.9:1). Most (46.0%) of the urinary stone diseases were between 0-19 year age group both in males and females. The median age was 20 years (range from 2-74 years) and the mean was 25.4 years. Urinary bladder stones were the most common urinary tract stone diseases accounting for 47 (46.0%) followed by renal stones 29 (28.4%), ureteric 16 (15.6%) and urethral 10 (9.8%) stone disease; in that order of frequency. The geographical back ground of the patients with urinary tract stone disease in this report has shown that majorities (53.7%) were from urban and the remaining (44.2%) were from the rural areas. This study has depicted that urinary bladder stone diseases are the most common stone diseases affecting the younger age group. Since this is an institutional based study, it underestimates the magnitude and the pattern of urinary stone diseases at all level. Nevertheless, the audit provides useful information on the socio demographic variables, localization and the geographic back ground of the patients.

    Several factors cause urinary tract infection (UTI) to be a relevant complication of the gestational period, aggravating both the maternal and perinatal prognosis. For many years, pregnancy has been considered to be a factor predisposing to all forms of UTI. Today, it is known that pregnancy, as an isolated event, is not responsible for a higher incidence of UTI, but that the anatomical and physiological changes imposed on the urinary tract by pregnancy predispose women with asymptomatic bacteriuria (AB) to become pregnant women with symptomatic UTI. AB affects 2 to 10% of all pregnant women and approximately 30% of these will develop pyelonephritis if not properly treated. However, a difficult-to-understand resistance against the identification of AB during this period is observed among prenatalists. The diagnosis of UTI is microbiological and it is based on two urine cultures presenting more than 10(5) colonies/mL urine of the same germ. Treatment is facilitated by the fact that it is based on an antibiogram, with no scientific foundation for the notion that a pre-established therapeutic scheme is an adequate measure. For the treatment of pyelonephritis, it is not possible to wait for the result of culture and previous knowledge of the resistance profile of the antibacterial agents available for the treatment of pregnant women would be the best measure. Another important variable is the use of an intravenous bactericidal antibiotic during the acute phase, with the possibility of oral administration at home after clinical improvement of the patient. At our hospital, the drug that best satisfies all of these requirements is cefuroxime, administered for 10-14 days. Third-generation cephalosporins do not exist in the oral form, all of them involving the inconvenience of parenteral administration. In view of their side effects, aminoglycosides are considered to be inadequate for administration to pregnant women. The inconsistent insinuation of contraindication of
