Genitourinary syndrome of menopause (GSM) is the leading cause of vaginal symptoms in breast cancer survivors treated with aromatase inhibitors. However, there are currently no effective treatment options available for women with a history of breast cancer. Recent research has established that changes in the vaginal microbiome may be linked to GSM. Most studies have assessed the microbiome without accounting for the estrogen status. It remains unknown whether the vaginal microbiome differ among patients with a low estrogenic state with and without vulvovaginal symptoms. To address such research questions, our study compares the vaginal microbiomes among breast cancer survivors treated with aromatase inhibitors with and without vulvovaginal symptoms. A total of 50 breast cancer survivors treated with aromatase inhibitors were recruited, among whom 25 had vulvovaginal symptoms and 25 had no vulvovaginal symptoms. Vaginal swabs were collected. DNA extraction, followed by sequencing of the V3-V4 regions of the 16S ribosomal RNA gene, were performed. Differential abundance analysis was conducted by linear discriminant analysis effect size. Taxonomy assignment, alpha diversity and beta diversity were examined. The relative abundance of genus Sneathia and genus Gardnerella was significantly increased in vulvovaginal symptoms group with no differences in bacterial diversity and richness.

BACKGROUND
Topical capsaicin has been used to treat vulvodynia but has been poorly studied for use in neuroproliferative provoked vestibulodynia (PVD); capsaicin decreases allodynia by blocking vanilloid receptors (TRPV1) on C-afferent nociceptors, but the therapy causes discomfort to the point of intolerance in some patients.
AIM
The present study evaluated tolerability and efficacy of topical capsaicin to treat neuroproliferative PVD.
METHODS
Patients with neuroproliferative PVD prescribed 0.025% capsaicin compounded in VersaBase cream were identified through prescription records. Outcome measures included the Female Sexual Function Index (FSFI), the Female Sexual Distress Scale-Revised, and a 22-question questionnaire assessing patient experience and treatment tolerability.
OUTCOMES
Among tolerant patients, capsaicin significantly decreased vestibular pain, but tolerance was highly variable.
RESULTS
Twenty-five patients responded to the follow-up questionnaire. The average age at presentation was 30 years (range, 18-52 years). Eighty percent of patients tolerated capsaicin application for the full 20 minutes within a median time of 1 to 2 weeks. Of the 16 patients reporting tolerance to 20-minute application, 12 (60%) experienced improvement in vestibular pain. On an 11-point numeric rating scale, the mean pain score was 8.96 and the median score was 10 with first application. Among all participants, 16 (64%) had reduction in pain during treatment. Fifty-six percent of patients would recommend capsaicin as a treatment for vulvar pain. Qualitative content analysis focused on categories of efficacy, value, and feasibility, which indicated that those able to tolerate the treatment experienced improvement while using the medication. The mean Female Sexual Distress Scale-Revised score was 35.96 at baseline compared with 25.09 at follow-up ( < .0001). On a numeric rating scale, the mean self-reported vulvar pain score was 8.2 at baseline compared with 5.35 when using capsaicin consistently ( < .0001). The mean FSFI pain domain score was 2.45 at baseline compared with 0.98 at follow-up ( = .005). While not statistically significant, the mean total FSFI score was 15.44 at baseline compared with 17.84 at follow-up ( = .3730).
CLINICAL IMPLICATIONS
Capsaicin is helpful for some patients with PVD, but thorough counseling is important because of highly variable tolerance.
STRENGTHS AND LIMITATIONS
Strengths include examination of a poorly studied therapy and inclusion of narrative responses from patients to inform counseling. Limitations include small sample size, retrospective design, and low survey response rate.
CONCLUSION
Patients should be appropriately selected and thoroughly counseled given high levels of intolerance, but capsaicin therapy may be considered for patients with neuroproliferative PVD who have failed conservative treatments and wish to avoid surgery.

Curcumin (CUR) is a natural compound that can be combined with miconazole (MCZ) to improve vulvovaginal candidiasis (VVC) caused by treatment's efficacy. This study aimed to develop ureasil-polyether (U-PEO) vaginal ovules loaded with CUR and MCZ for the treatment of VVC. Physicochemical characterization was performed by thermogravimetry (TGA), differential thermal analysis (DTA), Fourier transform infrared spectroscopy (FTIR), and in vitro release. Antifungal assays were used to determine minimum inhibitory concentrations (MICs) and synergism between CUR and MCZ, and the activity of U-PEO ovules were performed by microdilution and agar diffusion. TGA results showed high thermal stability of the hybrid ovules. In DTA, the amorphous character of U-PEO and a possible interaction between CUR and MCZ were observed. FTIR showed no chemical incompatibility between the drugs. In vitro release resulted in 80% of CUR and 95% of MCZ released within 144 h. The MICs of CUR and MCZ were 256 and 2.5 µg/mL, respectively. After combining the drugs, the MIC of MCZ decreased four-fold to 0.625 µg/mL, while that of CUR decreased eight-fold to 32 µg/mL. Synergism was confirmed by the fractional inhibitory concentration index (FICI) equal to 0.375. U-PEO alone showed no antifungal activity. U-PEO/MCZ and U-PEO/CUR/MCZ ovules showed the greatest zones of inhibition (≥18 mm). The results highlight the potential of the ovules to be administered at a lower frequency and at reduced doses compared to available formulations.

Review
BACKGROUND
Hemangiomas are aberrant proliferations of blood vessels and the most frequent benign pediatric soft tissue tumors. Although they are common, genital localization is rare. This study aimed to assist doctors in the diagnosis, management, and treatment of pediatric vulvovaginal hemangiomas by conducting a review of the literature.
METHODS
We conducted a literature review including papers published between August 2009 and May 2023.
RESULTS
While most hemangiomas are usually indolent and resolve with time, in some cases, especially cervicovaginal and uterine ones, they might present with severe symptoms like heavy bleeding and need further instrumental investigation for diagnosis, like CT or MRI. As for the treatment, many options are available, with medical therapy or expectant management being the first choice.
CONCLUSIONS
Vulvovaginal pediatric hemangiomas are rare and require more research on how to detect and manage these lesions, especially the symptomatic and the psychologically impacting ones. For the time being, treatment should be personalized based on the patient's situation and clinician's expertise.

In the present work, we evaluated the antifungal activities of two novel ebselen analogs, -allyl-benzisoselenazol-3(2H)-one (-allyl-bs) and -3-methylbutylbenzisoselenazol-3(2H)-one (-3mb-bs). Colorimetric and turbidity assays were performed to determine the minimum inhibitory concentration (MIC) of these compounds in S1 (fluconazole-sensitive) and S2 (fluconazole-resistant) strains of . -3mb-bs was more active than the -allyl-bs compound. It is noteworthy that the concentration of -3mb-bs observed to inhibit fungal growth by 50% (18.2 µM) was similar to the concentration observed to inhibit the activity of the yeast plasma membrane H-ATPase (Pma1p) by 50% (19.6 µM). We next implemented a mouse model of vulvovaginal candidiasis (VVC) using the S1 strain and examined the mouse and yeast proteins present in the vaginal lavage fluid using proteomics. The yeast proteins detected were predominately glycolytic enzymes or virulence factors associated with while the mouse proteins present in the lavage fluid included eosinophil peroxidase, desmocollin-1, and gasdermin-A. We then utilized the -3mb-bs compound (12.5 mg/kg) in the mouse VVC model and observed that it significantly reduced the vaginal fungal burden, histopathological changes in vagina tissue, and expression of myeloperoxidase (MPO). All in all, the present work has identified a potentially promising drug candidate for VVC treatment.

Background Urogenital health is a necessary part of health for all women, especially in the postmenopausal age group. We suspected that the increased incidence of vulvovaginal atrophy (VVA) had some or other effects on the quality of life of older women. So, we aimed to study VVA/genitourinary syndrome of menopause (GSM) and its impact on the quality of life of postmenopausal women in Central India. Despite its significant prevalence and detrimental impact on women's health, VVA/GSM is underdiagnosed and undertreated. In view of the feminization of aging, VVA management is becoming increasingly crucial. This study contributes to postmenopausal women's understanding that keeping their urogenital and sexual longevity is a critical step toward healthy living and gender equality. Given its relationship with urogynecological conditions, this study will help to evaluate both subjectively and objectively the incidence of symptoms related to VVA and its effects on the quality of life of postmenopausal women. This will eventually help to understand the need to address this issue while making postmenopausal women health-related policies. Potential remedies to overcome the obstacles currently preventing patient-HCP interactions addressing sexual health include providing communication tools to facilitate the "uncomfortable" conversation, educating women, and providing enough training for healthcare professionals. Methods The current study was conducted at a rural tertiary healthcare center in Central India and is a cross-sectional study. The study population taken into consideration were all the postmenopausal women between the age group 45 and 75 years with at least one vulvovaginal symptom attending the Outpatient Department (OPD). The total study sample size was 100 women. Further study was conducted by interview method using a questionnaire by the principal investigator. Data was gathered with the help of a pretested questionnaire in the patient's language. Symptoms related to GSM were studied by the vaginal symptom Bothersomeness Scale. Further, a gynecological clinical examination for the confirmation of VVA was carried out, which included a gynecological physical examination. The Vaginal Health Index (VHI) was calculated for each female using the score scale. Assessment of the quality of life of postmenopausal females using the Day-to-Day Impact of Vaginal Aging (DIVA) Questionnaire was performed. Results The majority of females (34%) who presented with the symptoms were in the category of 55-60 years followed by 22% in the age group of 61-65 years. The most common symptoms experienced by females were vaginal dryness (77%) followed by vaginal discharge (74%). Our study confirmed that 79% of the total females included in the study have a VHI score of less than 15, i.e., they suffer from VVA, thus presenting our incidence at 79%. Conclusion According to the surveys discussed in this research, a significant portion of postmenopausal women have symptoms linked to VVA that have a negative impact on their quality of life, including their sexual relationships and self-esteem.

Review
ABSTRACT
Although numerous studies have demonstrated the impact of microbiome manipulation on human health, research on the microbiome's influence on female health remains relatively limited despite substantial disease burden. In light of this, we present a selected review of clinical trials and preclinical studies targeting both the vaginal and gut microbiomes for the prevention or treatment of various gynecologic conditions. Specifically, we explore studies that leverage microbiota transplants, probiotics, prebiotics, diet modifications, and engineered microbial strains. A healthy vaginal microbiome for females of reproductive age consists of lactic acid-producing bacteria predominantly of the Lactobacillus genus, which serves as a protective barrier against pathogens and maintains a balanced ecosystem. The gut microbiota's production of short-chain fatty acids, metabolism of primary bile acids, and modulation of sex steroid levels have significant implications for the interplay between host and microbes throughout the body, ultimately impacting reproductive health. By harnessing interventions that modulate both the vaginal and gut microbiomes, it becomes possible to not only maintain homeostasis but also mitigate pathological conditions. While the field is still working toward making broad clinical recommendations, the current studies demonstrate that manipulating the microbiome holds great potential for addressing diverse gynecologic conditions.
LAY SUMMARY
Manipulating the microbiome has recently entered popular culture, with various diets thought to aid the microbes that live within us. These microbes live in different locations of our body and accordingly help us digest food, modulate our immune system, and influence reproductive health. The role of the microbes living in and influencing the female reproductive tract remains understudied despite known roles in common conditions such as vulvovaginal candidiasis (affecting 75% of females in their lifetime), bacterial vaginosis (25% of females in their lifetime), cervical HPV infection (80% of females in their lifetime), endometriosis (6-10% of females of reproductive age), and polycystic ovary syndrome (10-12% of females of reproductive age). Here, we review four different approaches used to manipulate the female reproductive tract and gastrointestinal system microbiomes: microbiota transplants, probiotics, prebiotics, and dietary interventions, and the use of engineered microbial strains. In doing so, we aim to stimulate discussion on new ways to understand and treat female reproductive health conditions.

Environmental sustainability is an increasing challenge in the pharmaceutical field, leading to the search for eco-friendly active ingredients. Among natural ingredients, propolis arises as an excellent alternative, being a complex substance with pharmacological properties. This work aims to explore the potential of propolis as a new pharmaceutical ingredient for the replacement of conventional vulvovaginal antifungals. Propolis extracts were obtained by Ultrasound-Assisted Extraction using different solvents (water, water/ethanol (50:50, /), and ethanol). Afterwards, the extracts were characterized regarding total phenolic content (TPC), antioxidant/antiradical activities, radical scavenging capacity, antifungal activity against strains of Candida species, and viability effect on two female genital cell lines. The aqueous extract achieved the best TPC result as well as the highest antioxidant/antiradical activities and ability to capture reactive oxygen species. A total of 38 phenolic compounds were identified and quantified by HPLC, among which ferulic acid, phloridzin and myricetin predominated. Regarding the anti- spp. activity, the aqueous and the hydroalcoholic extracts achieved the best outcomes (with MIC values ranging between 128 and 512 μg/mL). The cell viability assays confirmed that the aqueous extract presented mild selectivity, while the hydroalcoholic and alcoholic extracts showed higher toxicities. These results attest that propolis has a deep potential for vulvovaginal candidiasis management, supporting its economic valorization.

Review
Vulvovaginal candidiasis (VVC) is the second most common cause of vaginal infection globally after bacterial vaginosis (BV) and associated with adverse reproductive and obstetric outcomes, including preterm delivery, sexually transmitted infections and pelvic inflammatory disease. Although effective control of VVC is achievable with the use of traditional treatment strategies (i.e., antifungals), the possibility of drug intolerance, treatment failure and recurrence, as well as the appearance of antifungal-resistant species remain critical challenges. Therefore, alternative therapeutic strategies against VVC are urgently required. In recent years, an improved understanding of the dysbiotic vaginal microbiota (VMB) during VVC has prompted the consideration of administering -biotics to restore the balance of the VMB within the context of VVC prevention and treatment. Here, we aim to summarize the current evidence of the anti- effects of probiotics, postbiotics and synbiotics and their potential use as an alternative/complementary therapy against VVC. Additionally, this review discusses advantages and challenges associated with the application of -biotics in VVC to provide guidance for their later use. We also review new developments in VVC therapy, i.e., vaginal microbiota transplantation (VMT) as an emerging live biotherapeutic therapy against VVC and discuss existing shortcomings associated with this nascent field, expecting to stimulate further investigations for introduction of new therapies against VVC.

Cases of vulvovaginitis caused by genus are exceedingly uncommon, with only a handful of instances having been described for this causative species. This report describes a rare case of vulvovaginitis suspected to be caused by in a 58-year-old woman residing in an urban area of Hanoi city, Vietnam. The patient with a 10-year history of depression and type 2 diabetes mellitus was admitted to the hospital due to vulvar itching and vaginal discharge. Vaginal swabs confirmed the presence of a yeast infection by direct microscopic examination with 10% KOH and culture on CHROMagar Candida. The yeast was identified as using genetic sequencing tools. The patient's treatment plan involved topical clotrimazole and a daily oral dose of 200 mg of itraconazole for 7 days. This comprehensive treatment approach resulted in the patient's full recovery. This is the first reported case of vulvovaginitis attributed to in humans worldwide.
