Review
New therapeutic options are being considered to treat genitourinary syndrome of menopause (GSM), such as vaginal laser, ospemifene, or prasterone, but there is no explicit agreement in the scientific community for its use. Some concerns have arisen on how to evaluate the improvement of GSM symptoms. In 2003, the FDA suggested possible end points for this purpose: change in severity of symptoms, change in vaginal pH, and change in vaginal maturation index (VMI). Contrarily, the most common assessment tools used to quantify severity and improvement of GSM nowadays are the visual analog scale of GSM symptoms, the vaginal health index, and the female sexual function index. In our opinion, subjective and objective variables to evaluate GSM can be differentiated, and not many of the considered objective outcomes are used in the recent literature assessing GSM. There is the possibility that some therapies present only subjective improvement, giving place to a possible placebo effect that is not being evaluated. To conclude, there is a demand to evaluate whether vaginal pH and VMI are enough to assess objectively GSM changes or new objective approaches should be audited.

Review
Ibrexafungerp (IBX) is a new antifungal drug that recently entered the antifungal landscape. It disrupts fungal cell wall synthesis by non-competitive inhibition of the β-(1,3)-D-glucan (BDG) synthase enzyme. It has demonstrated activity against a range of pathogens including and spp., as well as retaining its activity against azole-resistant and echinocandin-resistant strains. It also exhibits anti-biofilm properties. Pharmacokinetic (PK) studies revealed favorable bioavailability, high protein binding, and extensive tissue distribution with a low potential for CYP-mediated drug interactions. It is characterized by the same mechanism of action of echinocandins with limited cross-resistance with other antifungal agents. Resistance to this drug can arise from mutations in the genes, primarily mutations in . In vivo, IBX was found to be effective in murine models of invasive candidiasis (IC) and invasive pulmonary aspergillosis (IPA). It also showed promising results in preventing and treating infections. Clinical trials showed that IBX was effective and non-inferior to fluconazole in treating vulvovaginal candidiasis (VVC), including complicated cases, as well as in preventing its recurrence. These trials positioned it as a Food and Drug Administration (FDA)-approved option for the treatment and prophylaxis of VVC. Trials showed comparable responses to standard-of-care in IC, with favorable preliminary results in infections in terms of efficacy and tolerability as well as in refractory cases of IC. Mild adverse reactions have been reported including gastrointestinal symptoms. Overall, IBX represents a significant addition to the antifungal armamentarium, with its unique action, spectrum of activity, and encouraging clinical trial results warranting further investigation.

Review
-mediated vulvovaginal candidiasis (VVC) is a significant challenge in clinical settings, owing to the inefficacy of current antifungals in modulating virulence, development of resistance, and poor penetration into the biofilm matrix. Various predisposition factors are molecular drivers that lead to the dysbiosis of normal microflora of the vagina, upregulation of central metabolic pathways, morphogenesis, hyphal extension, adhesion, invasion, and biofilm formation leading to chronic infection and recurrence. Hence, it is crucial to understand the molecular mechanism behind the virulence pathways driven by those drivers to decode the drug targets. Finding innovative solutions targeting fungal virulence/biofilm may potentiate the antifungals at low concentrations without affecting the recurrence of resistance. With this background, the present review details the critical molecular drivers and associated network of virulence pathways, possible drug targets, target-specific inhibitors, and probable mode of drug delivery to cross the preclinical phase by appropriate models.

Vulvovaginal candidiasis (VVC) can alter the vaginal microbiome composition and structure, and this may be correlated with its variable treatment efficacy. Integrated analysis of the mycobiome and bacteriome in VVC could facilitate accurate diagnosis of infected patients and further decipher the characterized bacteriome in different types of VVC. Our mycobiome analysis determined two common types of VVC, which were clustered into two community state types (CSTs) featured by Candida glabrata (CST I) and Candida albicans (CST II). Subsequently, we compared the vaginal bacteriome in two CSTs of VVC and two other types of reproductive tract infections (RTIs), bacterial vaginosis (BV) and Ureaplasma urealyticum (UU) infection. The vaginal bacteriome in VVC patients was between the healthy and other RTIs (BV and UU) status, it bore the greatest resemblance to that of healthy subjects. While BV and UU patients have the unique vaginal microbiota community structure, which very different with healthy women. Compared with CST II, the vaginal bacteriome of CST I VVC was characterized by a key signature in BV. In comparison, CST II was featured by , the pathogen of UU. The findings of our study highlight the need for co-analysis and simultaneous consideration of vaginal mycobiome and bacteriome in the diagnosis and treatment of VVC to solve common clinical problems, such as unsatisfactory cure rates and recurrent symptoms. Fungi headed by C. albicans play a critical role in VVC but are not sufficient for its occurrence, indicating the involvement of other factors, such as the vaginal bacteriome. We found that different CST correspond to different bacterial composition in patients with VVC, and this could underlie the alteration of vaginal microorganism environment in VVC patients. We believe that this correlation should not be ignored, and it may be related to the unsatisfactory treatment outcomes and high recurrence rate of VVC. Here, we provided evidence for associations between vaginal bacteriome patterns and fungal infection. Screening specific biomarkers for three common RTIs paves a theoretical basis for further development of personalized precision treatment.

UNLABELLED
Vulvovaginitis is a common and challenging gynaecological problem in prepubertal and pubertal girls. Such an infection, owing to a wide range of aetiologies, if not responding to hygienic measures, needs further investigation through vaginal cultures, since treatment should be tailored accordingly. This study aimed to investigate the pathogens isolated in prepubertal and pubertal girls with signs and symptoms of vulvovaginitis. A total of 2314 symptomatic girls, 1094 prepubertal and 1220 pubertal, aged 2 to 16 years, were included. Vaginal samples were inoculated on specific culture plates followed by incubation in aerobic, anaerobic or CO atmosphere at 37 °C for 24 or 48 h, as appropriate. The identification of the isolated pathogens was carried out using Gram stain, conventional methods and the automated system VITEK 2 (BioMerieux, Marcy l'Etoile, France). Positive cultures were obtained from 587 (53.7%) of prepubertal girls and 926 (75.9%) of pubertal girls. A total of 613 and 984 pathogens were detected in prepubertal and pubertal subjects, respectively. Isolated bacteria included 40.1% and 22.8% Gram-positive cocci, 35.6% and 24.8% Gram-negative rods in the prepubertal and pubertal groups, respectively, with faecal pathogens being the most prevalent. Bacterial vaginosis was diagnosed in 22.8% of prepubertal and 37.9% of pubertal girls. Candida species were isolated mostly in the pubertal girls (14.5%).
CONCLUSION
Culture results should be evaluated with caution in children with vulvovaginitis. In the prepubertal girls, the most common isolated pathogens were opportunistic bacteria of faecal origin while girls in late puberty were more susceptible to bacterial vaginosis and vulvovaginal candidiasis.
WHAT IS KNOWN
• Vulvovaginitis is the most frequent and challenging reason for referral to paediatric and adolescent gynaecology services. • Microbiological examination can prove to be a significant tool to help diagnosis although results should be evaluated with caution in children.
WHAT IS NEW
• Significantly more positive vaginal cultures and pathogens were recorded in symptomatic pubertal girls compared to prepubertal children. • The prevalence of bacterial vaginosis was increased in both prepubertal and pubertal girls with vulvovaginitis although significantly more in girls at puberty.

Review
Oestrogen plays a vital role in maintaining a normal vulvovaginal epithelium, vaginal lubrication, as well as a healthy microbiome to ensure an acidic pH. The decrease in oestrogen levels in women going through menopause results in both physiological and physical changes of the genitourinary system, and more specifically the vulva. We conducted a literature review on the effects of low oestrogen levels on the physiology and function of the vulva and the vulvovaginal epithelium. 'Genitourinary syndrome of menopause' (GSM) is the term used to describe the signs and symptoms of a low oestrogen state. The symptoms and signs of GSM can overlap or coexist with other vulval dermatoses. Expert opinion is needed to diagnose and manage vulval dermatoses in menopause. This article will discuss the signs and symptoms of GSM, as well as the different management options available. Other vulval dermatoses that can be affected by hypo-oestrogenism are also reviewed.

Comparative Study
The present study focused on the characteristics of the vaginal microbiomes in prepubertal girls with and without vulvovaginitis. We collected 24 vaginal samples and 16 fecal samples from 10 girls aged 3-9 years with vulvovaginitis and 16 healthy girls of the same age. The samples were divided into three groups: fecal swabs from healthy controls (HF), vaginal swabs from healthy controls (HVS), and vaginal swabs from girls with vulvovaginitis (VVS). Sequencing of the V3-V4 region of the 16S rDNA gene was performed with the NovaSeq PE250 platform to reveal the vaginal microbial community structure in healthy prepubertal girls and vulvovaginitis-associated microbiota. The intestinal microbiomes of healthy children were also analyzed for comparison. This study revealed that the healthy vaginal tract in prepubertal girls was dominated by Prevotella, Porphyromonas, Ezakiella, and Peptoniphilus species, with a high diversity of microbiota. The vulvovaginitis-associated microbiota were dominated by Streptococcus, Prevotella, Haemophilus, and Granulicatella, with lower diversity than that in healthy girls. Furthermore, the compositions of the vaginal and intestinal microbiomes were completely different. ANOSIM, MRPP, Adonis, and AMOVA were used to analyze the beta diversity, and the results showed that there were significant differences in the microbial communities among the three groups. Lactobacillus deficiency and high bacterial diversity were characteristics of the vaginal microbiome in healthy prepubertal girls; this is inconsistent with that in reproductive-age women. The vulvovaginitis-associated vaginal microbiota differed dramatically from normal microbiota, and the main causative agents were not fecal in origin.

Review
Vulvovaginal candidiasis (VVC) is a real gynecological problem among women of reproductive age from 15 to 49. A recent analysis showed that 75% of women will have an occurrence at least once per year, while 5% are observed to have recurrent vaginal mycosis-these patients may become unwell four or more times a year. This pathology is caused in 85-90% of cases by fungi of the species. It represents an intractable medical problem for female patients due to pain and pruritus. Due to the observation of an increasing number of strains resistant to standard preparations and an increase in the recurrence of this pathology when using local or oral preferential therapy, such as fluconazole, an analysis was launched to develop alternative methods of treating VVC using herbs such as dill, turmeric, and berberine. An in-depth analysis of databases that include scientific articles from recent years made it possible to draw satisfactory conclusions supporting the validity of herbal therapy for the pathology in question. Although phytotherapy has not yet been approved by the Food and Drug Administration, it appears to be a promising therapeutic solution for strains that are resistant to existing treatments. There is research currently undergoing aimed at comparing classical pharmacotherapy and herbal therapy in the treatment of vaginal candidiasis for the purpose of increasing medical competence and knowledge for the care of the health and long-term comfort of gynecological patients.

Indian Journal of Sexually Transmitted... 2021Vaginal candidiasis is one of the most common vaginal infections in women of reproductive age group caused by species of fungi, a normal inhabitant of vagina.
BACKGROUND
Vaginal candidiasis is one of the most common vaginal infections in women of reproductive age group caused by species of fungi, a normal inhabitant of vagina.
AIMS
The aim is to study the culture characteristics, species prevalence, and drug sensitivity of vulvovaginal candidiasis (VVC) among females with genital pruritus and discharge per vaginum who are proved to have infection by a vaginal smear study.
MATERIALS AND METHODS
A prospective study was done on female patients aged 18 years attending the Sexually Transmitted Diseases Clinic of the Department of Dermato-Venereo-Leprology (DVL), Tirunelveli Medical College, with complaints of genital pruritus and vaginal discharge over a period of 1½ years from 2013 to 2015. After clinical examination, vaginal discharge was smeared for wet mount, potassium hydroxide mount, and Gram stain. Those with pseudohyphae were chosen for culture, speciation, and drug sensitivity.
RESULTS
The most common age group affected was 18-35 years. The most common predisposing factor was HIV infection-induced immunosuppression (48.7%), followed by antibiotic usage and diabetes mellitus. Clinical presentation of VVC was similar in HIV-positive and HIV-negative patients. Recurrent VVC makes up 12% of total cases with most common species being whereas among the non-. Drug sensitivity pattern of showed the highest sensitivity to nystatin 85.7%, followed by triazoles (75%-85%) with ketoconazole being more resistant (40%-60%), and was similar in and non-.
LIMITATIONS
Exclusion of unmarried and pregnant women and lack of follow-up were limitations in our study.
CONCLUSIONS
According to our study, elimination of predisposing factors, speciation of fungus, and treatment based on drug sensitivity pattern will reduce the incidence of VVC.
