RESUMO

Within the vaginal ecosystem, lactobacilli and Gardnerella spp. likely interact and influence each other's growth, yet the details of this interaction are not clearly defined. Using medium simulating vaginal fluid and a two-chamber co-culturing system to prevent cell-to-cell contact between the bacteria, we examined the possibility that Lactobacillus jensenii 62B (Lj 62B) and/or G. piotii (Gp) JCP8151B produce extracellular factors through which they influence each other's viability. By 24 h post-inoculation (hpi) in the co-culture system and under conditions similar to the vaginal environment - pH 5.0, 37 °C, and 5% CO2, Lj 62B viability was not affected but Gp JCP8151B had been eliminated. Cell-free supernatant harvested from Lj 62B cultures (Lj-CFS) at 20 hpi, but not 16 hpi, also eliminated Gp JCP8151B growth. Neither lactic acid nor H2O2 production by Lj 62B was responsible for this effect. The Lj-CFS did not affect viability of three species of lactobacilli or eight species of Gram-positive and Gram-negative uropathogens but eliminated viability of eight different strains of Gardnerella spp. Activity of the inhibitory factor within Lj-CFS was abolished by protease treatment and reduced by heat treatment suggesting it is most likely a bacteriocin-like protein; fractionation revealed that the factor has a molecular weight within the 10-30 kDa range. These results suggest that, in medium mimicking vaginal fluid and growth conditions similar to the vaginal environment, Lj 62B produces a potential bacteriocin-like inhibitory substance (Lj-BLIS) that clearly targets Gardnerella spp. strains. Once fully characterized, Lj-BLIS may be a potential treatment for Gardnerella-related BV that does not alter the vaginal microflora.

RESUMO

BACKGROUND: Glycogen metabolism by Lactobacillus spp. that dominate the healthy vaginal microbiome contributes to a low vaginal pH (3.5-4.5). During bacterial vaginosis (BV), strict and facultative anaerobes including Gardnerella vaginalis become predominant, leading to an increase in the vaginal pH (> 4.5). BV enhances the risk of obstetrical complications, acquisition of sexually transmitted infections, and cervical cancer. Factors critical for the maintenance of the healthy vaginal microbiome or the transition to the BV microbiome are not well defined. Vaginal pH may affect glycogen metabolism by the vaginal microflora, thus influencing the shift in the vaginal microbiome. RESULTS: The medium simulating vaginal fluid (MSVF) supported growth of L. jensenii 62G, L. gasseri 63 AM, and L. crispatus JV-V01, and G. vaginalis JCP8151A at specific initial pH conditions for 30 d. L. jensenii at all three starting pH levels (pH 4.0, 4.5, and 5.0), G. vaginalis at pH 4.5 and 5.0, and L. gasseri at pH 5.0 exhibited the long-term stationary phase when grown in MSVF. L. gasseri at pH 4.5 and L. crispatus at pH 5.0 displayed an extended lag phase over 30 d suggesting inefficient glycogen metabolism. Glycogen was essential for the growth of L. jensenii, L. crispatus, and G. vaginalis; only L. gasseri was able to survive in MSVF without glycogen, and only at pH 5.0, where it used glucose. All four species were able to survive for 15 d in MSVF with half the glycogen content but only at specific starting pH levels - pH 4.5 and 5.0 for L. jensenii, L. gasseri, and G. vaginalis and pH 5.0 for L. crispatus. CONCLUSIONS: These results suggest that variations in the vaginal pH critically influence the colonization of the vaginal tract by lactobacilli and G. vaginalis JCP8151A by affecting their ability to metabolize glycogen. Further, we found that L. jensenii 62G is capable of glycogen metabolism over a broader pH range (4.0-5.0) while L. crispatus JV-V01 glycogen utilization is pH sensitive (only functional at pH 5.0). Finally, our results showed that G. vaginalis JCP8151A can colonize the vaginal tract for an extended period as long as the pH remains at 4.5 or above.

RESUMO

OBJECTIVE: This series of articles, titled The Vaginal Microbiome (VMB), written on behalf of the International Society for the Study of Vulvovaginal Disease, aims to summarize the recent findings and understanding of the vaginal bacterial microbiota, mainly regarding areas relevant to clinicians specializing in vulvovaginal disorders. MATERIALS AND METHODS: A search of PubMed database was performed, using the search terms "vaginal microbiome" with "dysbiosis," "bacterial vaginosis," "cytolytic vaginosis," "desquamative inflammatory vaginitis," and "aerobic vaginitis." Full article texts were reviewed. Reference lists were screened for additional articles. RESULTS: The second article in this series focuses on vaginal dysbiotic conditions. Dysbiosis is a term describing imbalances in bacterial communities. Given that lactobacillus-dominated microbiota are thought to be the most optimal, vaginal dysbiosis is usually considered as lactobacilli-depleted VMB. Bacterial vaginosis (BV), the most common vaginal dysbiotic condition, is a polymicrobial disorder, considered the leading cause for vaginal discharge in women worldwide. In addition, we review the VMB in other vaginal conditions associated with lactobacilli depletion: desquamative inflammatory vaginitis and aerobic vaginitis. We also discuss the controversial diagnosis of cytolytic vaginosis, related with lactobacilli overgrowth. CONCLUSIONS: Bacterial vaginosis displays complex microbiology. The heterogeneity and diversity within the genus Gardnerella may impact the progression of BV. Bacterial biofilms may contribute to the etiology and persistence of BV, and various bacteria may affect its clinical presentation and pathogenicity. Lack of lactobacilli is not always accompanied by an overgrowth of anaerobes.

RESUMO

OBJECTIVE: This series of articles, titled The Vaginal Microbiome, written on behalf of the International Society for the Study of Vulvovaginal Disease, aims to summarize the current findings and understanding of the vaginal bacterial microbiota, mainly regarding areas relevant to clinicians specializing in vulvovaginal disorders. MATERIALS AND METHODS: A database search of PubMed was performed, using the search terms "vaginal microbiome" (VMB) with "research," "normal," "neonate," "puberty," "adolescent," "menopause," and "ethnicities," as well as "human microbiome project." Full article texts were reviewed. Reference lists were screened for additional articles. RESULTS: In the last 2 decades, many studies applying molecular techniques were performed, intending to characterize the vaginal microbiota. These studies advanced our understanding of how vaginal health is defined. The first article in this series focuses on the advancement of VMB research, technical definitions, the definition of "normal" VMB, and the dynamics of VMB throughout women's lives. CONCLUSIONS: Understanding how microorganisms inhabiting the vagina interact with each other and with the host is important for a more complete understanding of vaginal health. The clinical application of microbial community sequencing is in its beginning, and its interpretation regarding practical clinical aspects is yet to be determined.

RESUMO

OBJECTIVE: This series of articles, titled The Vaginal Microbiome (VMB), written on behalf of the International Society for the Study of Vulvovaginal Disease, aims to summarize the recent findings and understanding of the vaginal bacterial microbiota, mainly regarding areas relevant to clinicians specializing in vulvovaginal disorders. MATERIALS AND METHODS: A search of PubMed database was performed, using the search terms "vaginal microbiome" with "reproduction," "infertility," "fertility," "miscarriages," "pregnancy" "cervical cancer," "endometrial cancer," and "ovarian cancer." Full article texts were reviewed. Reference lists were screened for additional articles. RESULTS: The fourth article of this series focuses on 2 distinct areas: the role of VMB in various aspects of human reproduction and, in sharp contrast, the association between the VMB and gynecologic malignancies. Several of the negative pregnancy outcomes have been associated with an altered VMB. Dysbiosis is remarkably linked with poor pregnancy outcomes from preconception to delivery. The associations between the microbiome and gynecologic cancers are described. CONCLUSIONS: The development of the microbiome research, enabled by molecular-based techniques, has dramatically increased the detection of microorganisms and the understanding of bacterial communities that are relevant to maternal-fetal medicine in health and disease, as well as in gynecological malignancies. Proving causation in cancer is difficult because of the complex interactive nature of potential causative factors. Certain elements of the microbiota have been shown to provoke inflammatory reactions, whereas others produce anti-inflammatory reactions; this balance might be impaired with a change in microbial variety.

RESUMO

OBJECTIVE: This series of articles, titled The Vaginal Microbiome (VMB), written on behalf of the International Society for the Study of Vulvovaginal Disease, aims to summarize the recent findings and understanding of the vaginal bacterial microbiota, mainly regarding areas relevant to clinicians specializing in vulvovaginal disorders. MATERIALS AND METHODS: A search of PubMed database was performed, using the search terms "vaginal microbiome" with "treatment," "diagnosis," and "research." Full article texts were reviewed. Reference lists were screened for additional articles. RESULTS: The currently available approaches for treating vaginitis or attempting to modulate the VMB are often insufficient. It has traditionally relied on the use of antibiotics, antiseptics, and antifungals. The fifth and last article of this series discusses the new and/or alternative therapeutic modalities. It addresses the role of probiotics, prebiotics and symbiotics, activated charcoal, biofilm disrupting agents, acidifying agents, phage therapy, and the concept of vaginal microbiome transplant. The challenges facing the research of VMB, including the clinical impact of microbiome manipulation, classification, and new diagnostic approaches are discussed. CONCLUSIONS: Microbiome research has grown dramatically in recent years, motivated by innovations in technology and decrease in analysis costs. This research has yielded huge insight into the nature of microbial communities, their interactions, and effects with their hosts and other microbes. Further understanding of the bacterial, fungal, phage, and viral microbiomes in combination with host genetics, immunologic status, and environmental factors is needed to better understand and provide personalized medical diagnostics and interventions to improve women's health.

RESUMO

OBJECTIVE: This series of articles, titled The Vaginal Microbiome (VMB), written on behalf of the International Society for the Study of Vulvovaginal Disease, aims to summarize the recent findings and understanding of the vaginal bacterial microbiota, mainly regarding areas relevant to clinicians specializing in vulvovaginal disorders. MATERIALS AND METHODS: A search of PubMed database was performed, using the search terms "vaginal microbiome" with "Candida," "vaginitis," "urinary microbiome," "recurrent urinary tract infections," "sexually transmitted infections," "human immunodeficiency virus," "human papillomavirus," "nonspecific vaginitis," "vulvodynia," and "vulvovaginal symptoms." Full article texts were reviewed. Reference lists were screened for additional articles. The third article in this series describes VMB in various urogenital disorders. RESULTS: Variable patterns of the VMB are found in patients with vulvovaginal candidiasis, challenging the idea of a protective role of lactobacilli. Highly similar strains of health-associated commensal bacteria are shared in both the bladder and vagina of the same individual and may provide protection against urinary tract infections. Dysbiotic VMB increases the risk of urinary tract infection. Loss of vaginal lactic acid-producing bacteria combined with elevated pH, increase the risk for sexually transmitted infections, although the exact protective mechanisms of the VMB against sexually transmitted infections are still unknown. CONCLUSIONS: The VMB may constitute a biological barrier to pathogenic microorganisms. When the predominance of lactobacilli community is disrupted, there is an increased risk for the acquisition of various vaginal pathogents. Longitudinal studies are needed to describe the association between the host, bacterial, and fungal components of the VMB.

RESUMO

BACKGROUND: Biofilm is a fundamental bacterial survival mode which proceeds through three main generalized phases: adhesion, maturation, and dispersion. Lactobacilli spp. (LB) are critical components of gut and reproductive health and are widely used probiotics. Evaluation of time-dependent mechanisms of biofilm formation is important for understanding of host-microbial interaction and development of therapeutic interventions. Time-dependent LB biofilm growth was studied in two systems: large biofilm output in continuous flow system (microfermenter (M), Institute Pasteur, France) and electrical impedance-based real time label-free cell analyzer (C) (xCELLigence, ACEA Bioscience Inc., San Diego, CA). L. plantarum biofilm growth in M system was video-recorded, followed by analyses using IMARIS software (Bitplane, Oxford Instrument Company, Concord, MA, USA). Additionally, whole genome expression and analyses of attached (A) and dispersed (D) biofilm phases at 24 and 48 h were performed. RESULTS: The dynamic of biofilm growth of L. plantarum was similar in both systems except for D phases. Comparison of the transcriptome of A and D phases revealed, that 121 transcripts differ between two phases at 24 h. and 35 transcripts - at 48 h. of M growth. The main pathways, down-regulated in A compared to D phases after 24 h. were transcriptional regulation, purine nucleotide biosynthesis, and L-aspartate biosynthesis, and the upregulated pathways were fatty acid and phospholipid metabolism as well as ABC transporters and purine nucleotide biosynthesis. Four LB species differed in the duration and amplitude of attachment phases, while growth phases were similar. CONCLUSION: LB spp. biofilm growth and propagation area dynamic, time-dependent processes with species-specific and time specific characteristics. The dynamic of LB biofilm growth agrees with published pathophysiological data and points out that real time evaluation is an important tool in understanding growth of microbial communities.

RESUMO

Maternal obesity in pregnancy has been linked to a spectrum of adverse developmental changes. Involvement of eCBs in obesity is well characterized. However, information regarding eCB physiology in obesity associated with pregnancy is sparse. This study evaluated fetomaternal hepatic, systemic, and placental eCB molecular changes in response to maternal consumption of a HFD. From ≥9 mo before conception, nonpregnant baboons ( Papio spp.) were fed a diet of either 45 (HFD; n = 11) or 12% fat or a control diet (CTR; n = 11), and dietary intervention continued through pregnancy. Maternal and fetal venous plasma samples were evaluated using liquid chromatography-mass spectrometry to quantify AEA and 2-AG. Placental, maternal and fetal hepatic tissues were analyzed using RT-PCR, Western blot, and immunohistochemistry. mRNA and protein expression of endocannabinoid receptors (CB1R and CB2R), FAAH, DAGL, MAGL, and COX-2 were determined. Statistical analyses were performed with the nonparametric Scheirer-Ray-Hare extension of the Kruskal-Wallis test to analyze the effects of diet (HFD vs. CTR), fetal sex (male vs. female), and the diet × sex interaction. Fetal weight was influenced by fetal sex but not by maternal diet. The increase in maternal weight in animals fed the HFD vs. the CTR diet approached significance ( P = 0.055). Maternal circulating 2-AG concentrations increased, and fetal circulating concentrations decreased in the HFD group, independently of fetal sex. CB1R receptor expression was detected in syncytiotrophoblasts (HFD) and the fetal endothelium (CTR and HFD). Placental CB2R protein expression was higher in males and lower in female fetuses in the HFD group. Fetal hepatic CB2R, FAAH, COX-2 (for both fetal sexes), and DAGLα (in male fetuses) protein expression decreased in the HFD group compared with the CTR group. We conclude that consumption of a HFD during pregnancy results in fetal systemic 2-AG and hepatic eCB deficiency.

RESUMO

OBJECTIVE: To report the type and prevalence of obstetric lacerations in a primigravid patient population after term spontaneous vaginal delivery without episiotomy. We examined the characteristics of lacerations in patients with postpartum dyspareunia or vulvodynia. STUDY DESIGN: This was a retrospective cohort of primiparous patients who spontaneously delivered in the residents' service at a large urban hospital under the supervision of Ob/Gyn faculty. Data was extracted from medical records using discharge diagnosis codes. Postpartum medical records and diagnostic codes of all patients with lacerations and postpartum dyspareunia were reviewed. The study was IRB approved. RESULTS: A cohort of 1617 primiparous patients with spontaneous vaginal delivery met the inclusion criteria. No tears were recorded in 836 patients (51.7%), first-degree tears in 413 cases (25.5%), second-degree tears in 271 cases (16.8%), third-degree tears in 58 cases (3.6%), fourth-degree in 21 cases (1.3%), and 18 cases (1.1%) were not further classified. Only 51 patients (3.2%) with first- and second-degree lacerations had postpartum complications, and merely 6 (0.4%) had vulvar pain and 6 (0.4%) had dyspareunia. However, 4 of those patients (33.3%) required vulvoplasty for complete dyspareunia remission. CONCLUSION: Almost half of patients with spontaneous vaginal delivery without episiotomy experienced some type of vaginal laceration. A first degree was documented in >25% of cases; however, <10% of those subsequently had complaints of vulvar pain or dyspareunia.

RESUMO

Vulvar pain syndrome or vulvodynia is a common multifactorial, heterogeneous, and chronic gynecological disorder with an estimated prevalence of up to 16%. This disorder seriously impacts the quality of life of women in several ways. The etiology of this condition is complex and remains elusive and requires an extensive differential diagnosis. A standard therapeutic approach for the management of vulvar pain is still under investigation and must be multidisciplinary. This review outlines the anatomic and pathophysiologic aspects of vulvar pain.

RESUMO

A safe and non-intrusive assessment of fetal health is not only crucial in low-risk gestations, but it is also the standard of care in high-risk pregnancies. Therefore, measuring blood flow across different vessels with non-invasive ultrasound methods has been accurately and painstakingly studied and published. Amongst these state-of-the-art techniques, umbilical artery (blood flow) Doppler velocimetry (UADV) has allowed for fetal well-being follow-ups and assess uteroplacental function, which obtains a more complete and clearer picture; particularly in regard to complicated pregnancies. Additionally, there are other modalities with diverse clinical applications that have emerged, including their clinical and research utilization in conditions such as fetal growth restriction (FGR), preeclampsia, fetal anemia, monochorionic twins vascular blood flow mismatch such as is in twin-to-twin transfusion syndrome, twin anemia polycythemia sequence, and twin reverse arterial perfusion sequence. Nevertheless, their applications regarding various other maternal-fetal diagnoses in the same way as premature births and/or multiple gestation surveillance have not been reported to hold strong clinical evidence. With that in regard, the purpose of this unique study was to give update of the multiple clinical applications of this very important obstetrical tool. Additionally, to review the pathophysiology as well as revisit their reported significant valid uses and occasional overuses. We also delved into quality control measures as related to the application of Doppler in obstetrics. Lastly, it is essential to look through and reflect on the future developments of this valuable, non-invasive, high-risk marvelous modern device.

RESUMO

Objective: Folliculitis is a skin infection and inflammation that develops in the hair follicles. While most cases of folliculitis are caused by bacterial infections, here is a case of folliculitis caused by the Candida fungi in an immunocompetent host. Case report: A 23-year-old non-diabetic immunocompetent female with recurrent vaginal candidiasis developed clusters of erythematous, pruritic papules in the pubic area. Upon evaluation, the clusters were determined to be folliculitis. Risk factors for folliculitis included shaving of the pubic area, hot tub use, and wearing of tight, restrictive clothing. Cultures and skin samples of the folliculitis demonstrated Candida albicans. The patient was subsequently and successfully treated with clotrimazole solution and cream. There was no recurrence of the folliculitis upon her 3-month follow-up appointment. Conclusion: Candida folliculitis is a rare condition in non-diabetic patients. The patient's history, risk factors and immune status assessment, and physical examination with proper diagnostic testing, are crucial steps in attaining the correct diagnosis.

RESUMO

OBJECTIVE: The purpose of our study was to compare clinical data regarding patients with pruritic lichen sclerosus (LS) at moderate or severe stages using 2 different therapies with a 5-year follow-up. MATERIALS AND METHODS: The study was approved by the institutional review board and was presented as a retrospective clinical data review of patients with pruritic biopsy diagnosis LS who underwent therapy at our university private practice from 2002 to 2005. We compared the results of a weekly topical application of high-potency steroid (HPS) with a combined HPS and monthly anesthetic/steroid subdermal injection (ASI). Outcomes were timed to achieve pruritus-free status, the number of symptomatic recurrences, and patient satisfaction with therapy. RESULTS: Fifty-four patients were diagnosed with LS between 2002 and 2005. There were 13 patients who had mild-stage, 25 who had moderate-stage, and 16 who had severe-stage LS. Five-year follow-up data on 17 patients with moderate-stage LS and 14 patients with severe-stage LS were obtained. Time to pruritus free was 6 weeks with ASI and 19 weeks with HPS for moderate-stage LS (p = .04) and 9 weeks with ASI and 24 weeks with HPS for severe-stage LS (p = .03). Recurrences were more frequent on HPS for moderate-stage LS (p = .04) but not significant with HPS for severe-stage LS (p = .15). Only ASI was successful at treating patients with recalcitrant pruritus. CONCLUSIONS: In our population, patients with symptomatic moderate-stage LS seem to have a more rapid and prolonged response to ASI than to HPS but are less satisfied with the injections.

RESUMO

Introduction: High infection rates after cesarean section are a major concern in the United States. A majority of antiseptics have irritant properties if they are not used as specified in companies' guidelines. Allergic contact dermatitis caused by povidone­iodine is infrequent and is misdiagnosed by clinicians who fail to differentiate allergy from irritation. This case report describes an allergic reaction to povidone­iodine after cesarean section. Case Presentation: A 28-year-old underwent a repeat low transverse cesarean-section at 39 weeks of gestation. The patient informed the medical team that she had no known allergies and no significant past medical history. The new hospital protocol included cleaning the skin over the planned incision site multiple times with povidone­iodine 7.5% scrub followed by povidone­iodine 10% paint. The surrounding skin was prepped with chlorhexidine. The patient complained of an allergic reaction on her skin the night after the procedure, with severe itching, and stated that it got progressively worse. The patient was started on an oral regimen of steroids and hydroxyzine. The itching slowly improved and at discharge the patient was continued on hydroxyzine and steroids were discontinued. By the patient's six-week postpartum visit, skin hypopigmentation had completely resolved. Conclusion: This case illustrates a reaction to povidone­iodine after cesarean section. This allergic reaction could not be attributed to any other portions of the procedure.

RESUMO

Lichen simplex chronicus commonly presents as a distressing vaginal lesion caused by severe, cyclical itch-scratch behavior. Lichen simplex chronicus is diagnosed by obtaining a detailed medical history, performing a physical exam, and recording of self-reported symptoms. Lichen simplex chronicus can be treated by corticosteroids, immunomodulators, antiepileptics, antihistamines, antidepressants, and phototherapy. Our case describes a 55-year-old female patient who presented to a clinic with recurrent vaginal itching, combined with compulsive scratching behavior that disrupted daily functioning. Physical examination revealed hypertrophic nodules located on the labia minora with scaling and hyperpigmentation. And the patient was diagnosed with lichen simplex chronicus. Empirical treatment with behavioral modifications and clobetasol propionate cream with an occlusive dressing produced significant improvements in symptoms at a six-month follow-up. Lichen simplex chronicus can have unusual presentations and; therefore, must be carefully differentiated from infectious and malignant skin lesions.

RESUMO

Spontaneous uterine rupture is a catastrophic obstetric complication for both the mother and fetus. We highlight a case of a 32-year-old G2P1A0L1 Hispanic female at 36 weeks gestation who presented to the labor and delivery unit with minimal prenatal care, complaining of abdominal pains and vaginal bleeding. An abdominopelvic ultrasound confirmed an empty uterus and fetal demise in the abdominal cavity, leading to an exploratory laparotomy to evacuate the fetus. At surgery, a preterm sized fetus "en caul" with intact amnions was floating in the abdominal cavity and a hemostatic, complete rupture of the anterior uterine wall was discovered. Uterus was repaired and the patient recovered postoperatively without complications. Despite the best evidence suggesting that a history of low-transverse Cesarean section poses a low risk for spontaneous uterine rupture, this complication should always be considered and patients should be counseled regardless of the low risk should they desire a cesarean section.

RESUMO

OBJECTIVES: Female sexual and reproductive health is heavily influenced by the levels and ratios of Lactobacilli species and vaginal cytokines. Menopause marks a profound body change as it shifts to a natural and permanent non-reproductive state. Vulvovaginal diseases encompass a broad variety of sexual health conditions. Furthermore, both menopause and vulvovaginal diseases affect vaginal Lactobacilli and cytokine levels. Thus, this study aimed to investigate the correlation between menopause, vulvovaginal diseases, and vaginal Lactobacilli and cytokine levels. METHODS: Vaginal swab samples were collected as part of a prospective data bank creation to study vaginal conditions as approved by the Institutional Review Board of Texas Tech University Health Sciences Center, Lubbock, USA. This study utilized 38 samples in this database, which were assigned to the pre-menopausal with no vulvovaginal conditions (n = 20) and post-menopausal with vulvovaginal conditions (n = 18) groups. A real-time polymerase chain reaction was conducted to determine the relative concentration of Lactobacilli species, while cytokine analysis was performed using multiplex enzyme-linked immunosorbent assay immunoassay. The standardized mean difference, multivariate analysis of variance, and permutational unequal variance t test were used for the statistical analysis. RESULTS: Cytokines, interleukin (IL)-6, macrophage inflammatory protein-1α, IL-8, and Lactobacillus iners expression were significantly elevated in the control group compared to the study group (P = 0.03 for the cytokines, P = 0.0194 for Lactobacilli). CONCLUSIONS: The levels of vaginal cytokine and Lactobacillus profile were significantly different between the pre-menopausal and post-menopausal groups.
