RESUMO
INTRODUCTION AND HYPOTHESIS: The COVID-19 pandemic and the desire to "flatten the curve" of transmission have significantly affected the way providers care for patients. Female Pelvic Medicine and Reconstructive Surgeons (FPMRS) must provide high quality of care through remote access such as telemedicine. No clear guidelines exist on the use of telemedicine in FPMRS. Using expedited literature review methodology, we provide guidance regarding management of common outpatient urogynecology scenarios during the pandemic. METHODS: We grouped FPMRS conditions into those in which virtual management differs from direct in-person visits and conditions in which treatment would emphasize behavioral and conservative counseling but not deviate from current management paradigms. We conducted expedited literature review on four topics (telemedicine in FPMRS, pessary management, urinary tract infections, urinary retention) and addressed four other topics (urinary incontinence, prolapse, fecal incontinence, defecatory dysfunction) based on existing systematic reviews and guidelines. We further compiled expert consensus regarding management of FPMRS patients in the virtual setting, scenarios when in-person visits are necessary, symptoms that should alert providers, and specific considerations for FPMRS patients with suspected or confirmed COVID-19. RESULTS: Behavioral, medical, and conservative management will be valuable as first-line virtual treatments. Certain situations will require different treatments in the virtual setting while others will require an in-person visit despite the risks of COVID-19 transmission. CONCLUSIONS: We have presented guidance for treating FPMRS conditions via telemedicine based on rapid literature review and expert consensus and presented it in a format that can be actively referenced.

Reporting of clinical trials results for Proteflazid® in the drug formulation suppositories and vaginal swabs soaked in the solution of the drug to the local immunity of the female reproductive tract. AIM: The aim of study was to examine the state of local immunity in the reproductive tract of women with sexually transmitted diseases caused by human papillomavirus, herpes viruses (Type 1, 2) and mixed infection (herpes viruses + chlamydia). MATERIALS AND METHODS: The trials involved 216 women with viral sexually transmitted diseases: Cervical Dysplasia associated with papillomavirus infection (HPV) (Group 1); Herpes genitalis type 1 (HSV- 1) and type 2 (HSV-1) (Group 2); mixed infection - HSV-1, HSV-2 and chlamydia (Group 3). RESULTS: Treatment results have confirmed that Proteflazid® contributes to sustainable performance improvement of basic factors of local immunity - sIgA, lysozyme and complement component C3 in the cervical mucus for all three groups of women. CONCLUSIONS: Proteflazid® enhances level of local immunity markers (sIgA, lysozyme, C3 complement component) and improves their ratios. Also it intensifies anticontagious activity of mucosal protection and female reproductive system as whole, during treatment diseases caused by human papillomavirus, herpesvirus and mixed urogenital infections (herpesvirus and chlamydia).

The own observations results of urogenital, gastrointestinal and nasopharyngeal infectious factors that cause the development of reactive arthritis (PeA) are being presented. The greatest contribution to the development of this disease make Chlamidia trachomatis (36%), Streptococcus haemolyticus (pyogenes) (19%) and hepatitis viruses B and C (10%). As a result of the research a number of kinetic parameters of arginase and NO-synthase reactions in peripheral blood lymphocytes of patients with reactive arthritis was identified. The authentic increase of arginase activity in 3.3 times and eNO-synthase activity decrease by 1,9 times in peripheral blood lymphocytes of patients with PeA, compared to practically healthy donors were determined. Increased activity of arginase and iNO-synthase of lymphocytes indicates changes in immune cells functional activity, which may be due to impaired metabolic and regulatory processes in these cells caused by a bacterial or viral infection.

Bacterial infections, especially endogenous, are the frequent complications among hemodialyzed and renal transplant patients. In this study we assumed the prevalence of urogenital mycoplasmas and HPV among hemodialysed women. We examined 32 hemodialysed women aged 20-48 (mean 35.6 ± 8.23) and 100 healthy controls of the same ages. Two swabs were collected for detection of mycoplasmas and HPV. Culture of Ureaplasma spp. and M. hominis was performed using Mycoplasma IST2 (bioMérieux, France), Identificaton of U. parvum and U. urealyticum was performed by Kong. Primers described by Jensen were used for M. genitalium. For detection of high-risk HPV types Amplicor HPV (Roche Molecular System, CA) was used. Prevalence of urogenital mycoplasmas in the hemodialysed women (53.1%) was significantly higher (P = 0.0059), compared with controls (25%). In both groups, U. parvum was the most frequently isolated. Cooccurrence of urogenital mycoplasmas was shown in 75% of the HPV-positive hemodialysed women and in 30.4% of HPV-positive controls (P = 0.0461). Cooccurrence of urogenital mycoplasmas with HPV was significantly higher in hemodialysed women. The need to take into account these microorganisms in routine diagnostic, especially for hemodialysed patients, was demonstrated. Further studies to demonstrate the role of this cooccurrence in etiopathogenesis of infection in hemodialysed patients are required.

The prevalence of cytomegalovirus infection (CMVI) dictates the necessity of its in-depth investigation in the patients presenting with the signs of chronic inflammatory diseases of sexual organs. The objective of the present study was to estimate the effectiveness of combined laser therapy of inflammatory diseases of the urogenital tract accompanied by the reactivation of CMVI concomitant with other infections. The examination of 158 women presenting with cytomegalovirus infection revealed clinical and laboratory characteristics of the microbiocenosis. These data may be used to improve the effectiveness of diagnostic and therapeutic strategies for such patients. The combined treatment of the patients with the reactivated form of CMVI using josamycin and doxycycline monohydrate in combination with panavir and low-intensity laser irradiation based at the "Matrix-Urolog" laser complex resulted in the favourable outcome of therapy in the majority of the patients.

Simultaneous detection and identification of multiple pathogens is required in many diagnostic fields. In this study a novel method based on a multiplex ligase detection (LD)-polymerase chain reaction (PCR) and microarray (MLPM) is described to detect simultaneously several swine viruses involved in reproductive and/or respiratory problems. The multiplex diagnostic system was validated using standard plasmids, and clinical samples. Using this strategy as few as 10 copies of target plasmids were detected successfully. Each probe pair yielded specific positive signal only in its target site. In addition, when six target plasmids were present simultaneously sufficient robust signals were generated in their corresponding sites of six plasmid templates and no obvious signals were detected in non-target sites. Compared to real-time PCR, the MLPM showed specificities and sensitivities of 95.7-100% and 100% for 47 clinical samples tested, respectively. The results demonstrate that this novel assay is a specific, sensitive, and multiplex diagnostic method for detection of multiple pathogens and can also be adapted easily for diagnostic purposes.

Analysis of blood biochemistry in cytomegalovirus, papillomavirus infections and herpes simplex virus showed a significant decrease in blood albumins, a significant rise in total protein, the percentage of alpha2-globulins, and an increase in the activity of ALAT, aldolase 1.6. This reflects the activity of inflammation, reveals hepatic toxic activity, and indicates renal dysfunction and externally asymptomatic active processes in the liver.

The results of the polymerase chain reaction studies performed in 2006-2008 were used to make a retrospective analysis of the detection of urogenital herpesvirus infections in reproductive-aged women constituting the urban population of the central region of Russia. The study used both monotarget and mutiplex test systems to detect herpes simplex virus (HSV), cytomegalovirus (CMV), Epstein-Barr virus (EBV), human herpesvirus types 6 and 7. A total of about 7.500 referrals; the detection rate for HSV was about 1%; that for CMV was from 0.3 in 2006 to 1% in 2008; that for EBV was from 0.1% in 2006 to 0.3% in 2008. More than a half of HSV-, CMV-, or EBY-positive samples also contained DNA of other causative agents and some samples did two pathogens or more. Multiplex test systems for herpesviruses considerably enhance the efficiency of diagnostic studies and reduce the material and time costs of diagnosis.

BACKGROUND: Genital shedding of herpes simplex virus (HSV) type 2 occurs frequently. Anatomic patterns of genital HSV-2 reactivation have not been intensively studied. METHODS: Four HSV-2-seropositive women with symptomatic genital herpes attended a clinic daily during a 30-day period. Daily samples were collected from 7 separate genital sites. Swab samples were assayed for HSV DNA by quantitative polymerase chain reaction. Anatomic sites of clinical HSV-2 recurrences were recorded. RESULTS: HSV was detected on 44 (37%) of 120 days and from 136 (16%) of 840 swab samples. Lesions were documented on 35 (29%) of 120 days. HSV was detected at >1 anatomic site on 25 (57%) of 44 days with HSV shedding (median, 2 sites; range, 1-7), with HSV detected bilaterally on 20 (80%) of the 25 days. The presence of a lesion was significantly associated with detectable HSV from any genital site (incident rate ratio [IRR], 5.41; 95% confidence interval [CI], 1.24-23.50; P= .02) and with the number of positive sites (IRR, 1.19; 95% CI, 1. 01-1.40; P=.03). The maximum HSV copy number detected was associated with the number of positive sites (IRR, 1.62; 95% CI, 1.44-1.82; P<.001). CONCLUSIONS: HSV-2 reactivation occurs frequently at widely spaced regions throughout the genital tract. To prevent HSV-2 reactivation, suppressive HSV-2 therapy must control simultaneous viral reactivations from multiple sacral ganglia.

Here we report the results of studies in the simian immunodeficiency virus (SIV)-rhesus macaque model of intravaginal transmission of human immunodeficiency virus type 1 in the setting of genital ulcerative diseases. We document preferential association of vRNA with induced ulcers during the first days of infection and show that allogeneic cells of the inoculum traffic from the vaginal lumen to lymphatic tissues. This surprisingly rapid systemic dissemination in this cell-associated SIV challenge model thus reveals the challenges of preventing transmission in the setting of genital ulcerative diseases and illustrates the utility of this animal model in tests of strategies aimed at reducing transmission under these conditions.

Complete genomes of HPV102 (8,078 bp) and HPV106 (8,035 bp) were PCR amplified and cloned from cervicovaginal cells of a 49-year-old Hispanic female with reactive changes on her Pap test and a 42-year-old Hispanic female with a Pap test diagnosis of atypical squamous cells of unknown significance (ASCUS), respectively. The nucleotide sequence similarity of the complete L1 open reading frame (ORF) determined that HPV102 and HPV106 are most closely related to HPV83 (84.1 % identity) and HPV90 (83.5 % identity), respectively, placing them in the genital HPV groups, papillomaviruses species alpha3 and alpha15. HPV102 and HPV106 contain five early genes (E6, E7, E1, E2, and E4) and two late genes (L2 and L1), and both lack an E5 ORF. On the basis of phylogenetic analyses and available clinical information, these two novel HPV types expand the heterogeneity of HPVs detected in the lower genital tract.

To further investigate the vertical transmission route of human papillomavirus (HPV) and the indication for the choice of mode of delivery, the infective status of 152 asymptomatic pregnant wemen and the maternal-fetal transmission were studied. By using general primers in polymerase chain reaction (GP-PCR) combined with restriction fragment length polymorphism analysis, HPV DNA positive rate in cervical secretions and venous blood in asymptomatic pregnant women was 36.21% and 52.78%, respectively, and the identified genotypes were mainly HPV16 and 18. The maternal-fetal transmission rate of HPV via genital tract as well as blood was 40.91% and 57. 89%, respectively. It was concluded that besides the transmission route of genital tract and amniotic fluid, there was also transplacental transmission of HPV in utero. Therefore,in our opinion, it is not an absolut indication to perform a cesarean delivery for the pregnant women with HPV asymtomatic genital infection.

Human papillomavirus (HPV) is the most common sexually transmitted disease in both men and women. Prevalence rates are the highest for adolescents. Despite the high prevalence rates, sequelae of genital warts, dysplasia, and cancer are rare developments. Knowledge about the natural history, virology, and cancerous transformation has lead to improved viral detection, including the use of HPV DNA detection tests, screening efforts for HPV-related precancerous and cancerous lesions, and clinical interventions and treatments, including both therapeutic and prophylactic vaccinations.

Our objective is to gauge the prevalence of hepatitis C virus (HCV) antibodies among a population at risk of contracting sexually transmitted infections (STIs) and, thus, the efficiency with which the virus is transmitted sexually. The investigators undertook an unlinked anonymous HCV antibody testing study of residual syphilis serology specimens taken from attenders of genitourinary clinics in Glasgow, Edinburgh and Aberdeen during 1996/97. The results were linked to non-identifying risk information. Anti-HCV prevalences among non-injecting heterosexual men and women, and non-injecting homosexual/bisexual males ranged between 0 and 1.2%; the only exception to this was a 7.7% (4/52) prevalence among homosexual/bisexual males in Aberdeen. The overall anti-HCV prevalence for homosexual/bisexual males was 0.6% (4/668), for heterosexual males 0.8% (32/4135), for heterosexual females 0.3% (10/3035) and for injecting drug users 49% (72/148). Only 3 (all female) of the 46 non-injectors who were antibody positive were non-UK nationals or had lived abroad. HCV antibody positive injectors were less likely to have an acute STI and more likely to know their HCV status than non-injectors; no differences in these parameters were found between positive and negative non-injectors on anonymous HCV antibody testing. Our findings are in keeping with the prevailing view that HCV can be acquired through sexual intercourse but, for most people, the probability of this occurring is extremely low. Interventions to prevent the spread of HCV should be targeted mainly at injecting drug user (IDU) populations.

Despite the major differences in the clinical epidemiology of HIV and HPV infections, several lessons learned from the HIV epidemic may be relevant to future prevention of HPV infection. There has been a paradigm shift in conceptualizing the epidemiology of STDs; targets of prevention now include: (1) determinants of exposures of susceptibles to infectious persons; (2) the efficiency of transmission; and (3) the duration of infectiousness. Lessons learned that may be potentially relevant to HPV prevention include: (1) advances in treatment of HIV have been rapidly adopted, whereas advances in prevention have not; (2) therapeutic and preventive trials have been too brief in duration, sometimes failing to adequately address major problems with relapse that become evident later; and (3) involvement of affected individuals and populations in research and prevention efforts has been essential and useful. Specific suggestions for HPV prevention efforts are discussed.

BACKGROUND: Some human papillomaviruses (HPVs) are oncogenic in the cervix and are also associated with benign and malignant proliferations in other organs. Currently, the association of HPV with tumors of the lower respiratory tract is not so clearly defined because the studies are difficult to compare; series of cases reported from different geographic regions have used frozen or formalin fixed samples and a variety of techniques of HPV detection. METHODS: The authors studied the prevalence of HPV in a large series of 185 frozen bronchopulmonary tumor samples with a new solution hybridization technique, Hybrid Capture II assay. This test is largely applied in cervical pathology. Its sensitivity is very close to the sensitivity of PCR. It allows the detection of 18 mucosal HPV types, divided into 1 oncogenic and 1 nononcogenic group. RESULTS: Oncogenic HPV DNA was detected by the Hybrid Capture II assay in 5 cases (2.7%) of 185 (3 males and 2 females). In the rare positive cases detected, the authors could not find any consistent morphologic changes classically associated with HPV infection in anogenital lesions, such as koilocytosis. CONCLUSIONS: Oncogenic HPV DNA is detected in a small proportion of cases of bronchopulmonary carcinoma, and thus HPV infection appears to play a limited role in the tumorigenesis of most lung carcinomas.
