AIMS
Oxygen plays a crucial role in wound healing after prolapse surgery. Trauma to the vaginal vasculature might limit the delivery of oxygen to the surgical wound, which may negatively affect wound healing and regeneration of connective tissue. This possibly increases the future risk of recurrence. We aimed to determine the effects of vaginal prolapse surgery on the microcirculation of the vaginal wall.
METHODS
We evaluated the vaginal microcirculation in healthy participants without known vascular disease undergoing anterior and/or posterior colporrhaphy. We used incident dark-field imaging for in vivo assessment before and after (1 day, 2 weeks, and 6 weeks) surgery. We studied perfusion (microvascular flow index [MFI]), angioarchitecture (morphology/layout of microvessels) and capillary density.
RESULTS
Ten women were included. Interindividual differences were observed 1 day postoperatively with regard to perfusion and angioarchitecture. Microvascular flow at the surgical site was absent or significantly reduced in some participants, whereas normal microvascular flow was observed in others (MFI range 0-3). Perfusion and angioarchitecture had been restored in all participants after 6 weeks (MFI range 2-3), regardless of the extent of vascular trauma 1 day postoperatively.
CONCLUSIONS
The difference in the extent of vascular trauma between women undergoing seemingly identical surgical procedures suggests that some individuals are more susceptible to vascular trauma than others. Delivery of oxygen to the wound and subsequent wound healing may be compromised in these cases, which could be related to the development of anatomical recurrence. Future studies should investigate whether there is a relationship between the vaginal microvasculature and the recurrence of prolapse.

International Urogynecology Journal Oct 2022We sought to identify postoperative structural failure sites associated with long-term prolapse recurrence and their association with symptoms and satisfaction.
INTRODUCTION AND HYPOTHESIS
We sought to identify postoperative structural failure sites associated with long-term prolapse recurrence and their association with symptoms and satisfaction.
METHODS
Women who had a research MRI prior to native-tissue prolapse surgery were recruited for examination, 3D stress MRI, and questionnaires. Recurrence was defined by Pelvic Organ Prolapse Quantification System (POP-Q)Ba/Bp > 0 or C > -4. Measurements were performed at rest and maximum Valsalva ("strain") including vaginal length, apex location, urogenital hiatus (UGH), and levator hiatus (LH). Measures were compared between subjects and to women with normal support. Failure frequency was the proportion of women with measurements outside the normal range. Symptoms and satisfaction were measured using validated questionnaires.
RESULTS
Thirty-one women participated 12.7 years after surgery-58% with long-term success and 42% with recurrence. Failure site comparisons between success and failure were: impaired mid-vaginal paravaginal support (62% vs. 28%, p = 0.01), longer vaginal length (54% vs. 22%, p = 0.03), and enlarged urogenital hiatus (54% vs. 22%, p = 0.03). Apical paravaginal location had the lowest failure frequency (recurrence: 15% vs. success: 7%, p = 0.37). Patient satisfaction was high (recurrence: 5.0 vs. success: 5.0, p = 0.86). Women with bothersome bulge symptoms had a 33% larger UGH strain on POP-Q (p = 0.01), 8.7% larger resting UGH (p = 0.046), 11.5% larger straining LH (p = 0.01), and 9.3% larger resting LH (p = 0.01).
CONCLUSIONS
Abnormal low mid-vaginal paravaginal location (Level II), long vaginal length (Level II), and large UGH (Level III) were associated with long-term prolapse recurrence. Patient satisfaction was high and unrelated to anatomical recurrence. Bothersome bulge symptoms were associated with hiatus enlargement.

UNLABELLED
Bacterial vaginosis (BV) is characterized by shifts in the vaginal microbiota from Lactobacillus dominant to a microbiota with diverse anaerobic bacteria. Few studies have linked specific metabolites with bacteria found in the human vagina. Here, we report dramatic differences in metabolite compositions and concentrations associated with BV using a global metabolomics approach. We further validated important metabolites using samples from a second cohort of women and a different platform to measure metabolites. In the primary study, we compared metabolite profiles in cervicovaginal lavage fluid from 40 women with BV and 20 women without BV. Vaginal bacterial representation was determined using broad-range PCR with pyrosequencing and concentrations of bacteria by quantitative PCR. We detected 279 named biochemicals; levels of 62% of metabolites were significantly different in women with BV. Unsupervised clustering of metabolites separated women with and without BV. Women with BV have metabolite profiles marked by lower concentrations of amino acids and dipeptides, concomitant with higher levels of amino acid catabolites and polyamines. Higher levels of the signaling eicosanoid 12-hydroxyeicosatetraenoic acid (12-HETE), a biomarker for inflammation, were noted in BV. Lactobacillus crispatus and Lactobacillus jensenii exhibited similar metabolite correlation patterns, which were distinct from correlation patterns exhibited by BV-associated bacteria. Several metabolites were significantly associated with clinical signs and symptoms (Amsel criteria) used to diagnose BV, and no metabolite was associated with all four clinical criteria. BV has strong metabolic signatures across multiple metabolic pathways, and these signatures are associated with the presence and concentrations of particular bacteria.
IMPORTANCE
Bacterial vaginosis (BV) is a common but highly enigmatic condition that is associated with adverse outcomes for women and their neonates. Small molecule metabolites in the vagina may influence host physiology, affect microbial community composition, and impact risk of adverse health outcomes, but few studies have comprehensively studied the metabolomics profile of BV. Here, we used mass spectrometry to link specific metabolites with particular bacteria detected in the human vagina by PCR. BV was associated with strong metabolic signatures across multiple pathways affecting amino acid, carbohydrate, and lipid metabolism, highlighting the profound metabolic changes in BV. These signatures were associated with the presence and concentrations of particular vaginal bacteria, including some bacteria yet to be cultivated, thereby providing clues as to the microbial origin of many metabolites. Insights from this study provide opportunities for developing new diagnostic markers of BV and novel approaches for treatment or prevention of BV.

Acta Cirurgica Brasileira 2024To investigate inflammation and cell adhesion molecules in the vagina after ovarian ischemia-reperfusion (IR) injury.
PURPOSE
To investigate inflammation and cell adhesion molecules in the vagina after ovarian ischemia-reperfusion (IR) injury.
METHODS
20 Wistar albino female rats were divided into two groups: control, and IR groups. In IR group, blood flow was restricted for 2 hours for ovarian ischemia. Then, tissues were re-blood 2 hours for reperfusion. Vagina tissues were excised and processed for histopathological analysis. Histopathological and biochemical follow-ups were performed.
RESULTS
Both malondialdehyde and myeloperoxidase values were increased in IR group compared to control group. Glutathione content was decreased in IR group compared to control group. Epithelial degeneration, inflammation, dilatation, and nuclear factor-κB (NF-κB) expression were increased in IR group compared to control group. E-cadherin expression was significantly decreased in IR group. In the IR group, E-cadherin showed a positive reaction in adenomas, gland-like cryptic structures, cellular junctions with clustered inflammatory cells. In the IR group, NF-κB expression was increased in basement membrane, inflammatory cells, in blood vessels.
CONCLUSIONS
Ovarian ischemia caused degeneration of epithelial cells in the vaginal region and disruptions in the cell junction complex, which leads to activation of E-cadherin and NF-κB signaling pathway and alterations in reproductive and embryonal development in the vaginal region.

Review
BACKGROUND
Because female genital mutilation/cutting (FGM/C) leads to changes in normal genital anatomy and functionality, women are increasingly seeking surgical interventions for their FGM/C-related concerns.
AIM
To conduct a systematic review of empirical quantitative and qualitative research on interventions for women with FGM/C-related complications.
METHODS
We conducted systematic searches up to May 2016 in 16 databases to obtain references from different disciplines. We accepted all study designs consisting of girls and women who had been subjected to FGM/C and that examined a reparative intervention for a FGM/C-related concern. We screened the titles, abstracts, and full texts of retrieved records for relevance. Then, we assessed the methodologic quality of the included studies and extracted and synthesized the study data.
OUTCOMES
All outcomes were included.
RESULTS
Of 3,726 retrieved references, 71 studies including 7,291 women were eligible for inclusion. We identified three different types of surgical intervention: defibulation or surgical separation of fused labia, excision of a cyst with or without some form of reconstruction, and clitoral or clitoral-labial reconstruction. Reasons for seeking surgical interventions consisted of functional complaints, sexual aspirations, esthetic aspirations, and identity recovery. The most common reasons for defibulation were a desire for improved sexual pleasure, vaginal appearance, and functioning. For cyst excision, cystic swelling was the main reason for seeking excision; for reconstruction, the main reason was to recover identity. Data on women's experiences with a surgical intervention are sparse, but we found that women reported easier births after defibulation. Our findings also suggested that most women were satisfied with defibulation (overall satisfaction = 50-100%), typically because of improvements in their sexual lives. Conversely, the results suggested that defibulation had low social acceptance and that the procedure created distress in some women who disliked the new appearance of their genitalia. Most women were satisfied with clitoral reconstruction, but approximately one third were dissatisfied with or perceived a worsening in the esthetic look.
CLINICAL TRANSLATION
The information health care professionals give to women who seek surgical interventions for FGM/C should detail the intervention options available and what women can realistically expect from such interventions.
STRENGTHS AND LIMITATIONS
The systematic review was conducted in accordance with guidelines, but there is a slight possibility that studies were missed.
CONCLUSION
There are some data on women's motivations for surgery for FGM/C-related concerns, but little is known about whether women are satisfied with the surgery, and experiences appear mixed.

Review
Recurrent vulvovaginal infections (RVVI), a devastating group of mucosal infection, are severely affecting women's quality of life. Our understanding of the vaginal defense mechanisms have broadened recently with studies uncovering the inflammatory nature of bacterial vaginosis, inflammatory responses against novel virulence factors, innate Type 17 cells/IL-17 axis, neutrophils mediated killing of pathogens by a novel mechanism, and oxidative stress during vaginal infections. However, the pathogens have fine mechanisms to subvert or manipulate the host immune responses, hijack them and use them for their own advantage. The odds of hijacking increases, due to impaired immune responses, the net magnitude of which is the result of numerous genetic variations, present in multiple host genes, detailed in this review. Thus, by underlining the role of the host immune responses in disease etiology, modern research has clarified a major hypothesis shift in the pathophilosophy of RVVI. This knowledge can further be used to develop efficient immune-based diagnosis and treatment strategies for this enigmatic disease conditions. As for instance, plasma-derived MBL replacement, adoptive T-cell, and antibody-based therapies have been reported to be safe and efficacious in infectious diseases. Therefore, these emerging immune-therapies could possibly be the future therapeutic options for RVVI.

A healthy state of the vaginal microbiome can prevent vaginal disease and promote successful fertilization and healthy pregnancies. Little is known about the stability of the vaginal microbiome and the influence of factors such as diet and probiotics. While less explored, yeast probiotics have an interesting potential because of their immunomodulatory and pathogen inhibition capacities. In this study, we investigated the impact of the oral yeast probiotic Saccharomyces cerevisiae CNCM I-3856 on the vaginal microbiomes of 52 healthy women using 16S and internal transcribed spacer (ITS) amplicon sequencing and quantitative PCR (qPCR). The vaginal fungal loads remained low, even after oral yeast supplementation, complicating the analysis of the vaginal mycobiome. Lactobacillus crispatus and Lactobacillus iners were the most dominant species in our study population and were found to codominate in 23% of the baseline samples. , Streptococcus, and were also frequently found. The microbiome profiles were dynamic: 69% of women showed a shift in the dominant community members at least once during the 42-day sampling period. In addition, lower abundances were observed at the time points after menstruation. Higher relative abundances of with more L. inersdominated samples and a trend toward lower relative abundances of were observed in the probiotic group, but analyses of the effects of the yeast probiotic were complicated by differences already present at the onset of the study. Thus, our findings especially highlighted that the impact of menstruation and the stratification of women based on the dominant vaginal taxa before randomization and inclusion is important for future research: while the impact of the yeast probiotic on vaginal microbiome in healthy women was limited. How to define and promote a healthy state of the vaginal microbiome is not well understood. Knowledge of which underlying factors shape the microbial community composition of the vagina and how to modulate them will contribute to vaginal disease prevention and improve fertility. Here, we found that taking the menstrual cycle into account when designing a microbiome study is highly recommended: menstruation also showed to be poses an interesting time point for intervention because of the drop in the abundance of L. crispatus. Furthermore, the early stratification of groups (e.g., placebo versus treatment) according to the dominant taxa can be of high added value since menstruation impacts vaginal taxa differently, i.e., remains stable, in contrast to .

The vaginal microbiota of healthy women is dominated by lactobacilli, which exerts important health-promoting effects to the host. In the present study, 261 lactobacilli isolated from vagina of healthy women were screened for their potential probiotic characteristics. Safety features (haemolytic activity, antibiotic susceptibility, bile salt hydrolase activity) and functional properties (resistance to low pH and bile salts, lysozyme tolerance, gastrointestinal survival, antagonistic activity against pathogens, hydrophobicity, auto-aggregation, and co-aggregation abilities, hydrogen peroxide production, biofilm formation, exopolysaccharide production, adhesion capacity to both normal human vagina epithelial cells and Caco-2 epithelial cells, and lactic acid production) were in depth evaluated. Seven strains, identified as Lactobacillus rhamnosus, Lactobacillus helveticus and Lactobacillus salivarius fulfilled the criteria described above. Therefore, the vaginal ecosystem represents a suitable source of probiotic candidates that could be used in new functional formulates for both gastrointestinal and vaginal eubiosis.

Herlyn-Werner-Wunderlich syndrome (HWWS), defined by the triad of uterus didelphys, obstructed hemivagina and ipsilateral renal agenesis, is a rare Mullerian duct malformation, usually diagnosed after menarche, when symptoms related to haematocolpos arise. We report a case of a 14-year-old patient who presented to the emergency department complaining of proctalgia and pelvic pain treated in our medical centre. Ultrasound and abdomino-pelvic MRI imaging studies confirmed the diagnosis. Treatment was surgical incision of the vaginal septum. At the follow-up visit, after the initial procedure, excess vaginal tissue was excised using a hysteroscopic approach during diagnostic vaginoscopy. Vaginoscopy-assisted treatment of the patient proved to be a safe and effective minimally invasive treatment modality that resulted in symptomatic relief and fertility preservation. In conclusion, although premenarche is asymptomatic in the vast majority of cases, HWWS would be optimally diagnosed in childhood to avoid acute late complications, although it is usually first diagnosed after menarche as a result of haematocolpos. Gynaecologists should consider the syndrome in the presence of pelvic mass, renal agenesis, menstrual changes and cyclic pelvic pain.
