RESUMEN

PURPOSE: The present work seeks to develop, assess and refine a nanoethosomal vaginal in situ gel containing Berberine, aimed at enhancing its efficacy in treating Poly Cystic Ovary Syndrome (PCOS). This formulation aims to augment drug permeation, enable controlled release kinetics, and mitigate oral adverse effects commonly associated with Berberine administration. METHOD: Nanoethosomes formulated using diverse soya lecithin-ethanol concentrations within a 32 full-factorial-design, sought optimal formulations based on particle size and %entrapment-efficiency. Subsequent scrutiny involved PDI, Zeta potential and drug-content evaluation. TEM analysis authenticated morphology, while in vitro drug release from Nanoethosomes was examined. Pluronic F-127 concentrations (16%-21%w/v) were explored for the in situ gel, analyzing pH, gelation time and gelation temperature. The refined gel underwent evaluations for viscosity and in vitro diffusion. In vivo assessment covered pharmacokinetics, vaginal irritancy and Mifepristone-induced PCOS management, validated through histopathological and biochemical analysis, juxtaposing findings across normal, diseased, plain Berberine gel and standard metformin administered groups. RESULTS: Optimized Nanoethosomal Formulation(F3) displayed particle size of 183.5 nm, 82.58 % as %entrapment-efficiency, PDI of 0.137, -50.34 mV as zeta potential and 81.64 ± 1.57 % drug-content. TEM analysis confirmed spherical, nano-sized particles. In vitro studies exhibited 80.45 % drug release over 24 h. The formulated gel with 18 % Pluronic F-127 showed viscosity ranging from 193.01 ± 0.16cps to 1817.08 ± 1.67cps with temperature changes from 25 ± 2.0 °C to 38 ± 2.0 °C. In vitro diffusion revealed 85.99 %drug release from optimized gel. In vivo animal studies demonstrated increased plasma drug concentration, non-irritating properties in vaginal tests, and efficacy in managing Mifepristone-induced PCOS compared to other treatments. Short-term stability evaluations confirmed thermodynamic stability at room-temperature.

RESUMEN

INTRODUCTION: Pain experience, physical reaction, image quality and adverse events during Gel Instillation Sonohysterography (GIS) can differ using gels with different compositions. As a result, patient satisfaction can also be affected. The effect of two instillation gels, Endosgel versus ExEmgel, using both the Visual Analogue Scale (VAS) and a Continuous Pain Score Meter (CPSM) was therefore compared. METHODS: This single centre double blind randomised controlled trial included 80 women planned for outpatient GIS, diagnosed with abnormal intrauterine bleeding or fertility disorders and suspicion on an intrauterine abnormality. Patients were randomly allocated to the instillation of Endosgel containing chlorhexidine or ExEmgel without chlorhexidine. Primary outcome was reported pain during the procedure using VAS. Secondary outcomes included pain score measured using CPSM, satisfaction to the procedure and preference at 3 weeks and 3 months after the procedure and image quality. A cost benefit analysis was also performed. RESULTS: The reported median VAS concerning pain during gel instillation was comparable in the Endosgel and ExEmgel group, 2.50 (IQR 0.00-5.00) and 2.00 (IQR 0.00-5.75) respectively (p = 0.69). The median VAS of the entire procedure was also similar: both 2.00 (IQR 0.00-5.00) (p = 0.86). CPSM-scores were not significantly different either. Both groups were similar in image quality (p = 0.83) and patient's satisfaction (p = 0.36). CONCLUSION: Concerning the pain experienced during a GIS procedure and patients' satisfaction, the ExEmgel was not proven to be superior to the Endosgel. Our advice is to use the gel that is available at the lowest costs, as the image quality is the same for both Endosgel and ExEmgel.

RESUMEN

OBJECTIVES: This TRIPLE study was aimed to evaluate the efficacy of polycarbophil vaginal gel (PCV) in treating symptoms of vaginal atrophy (VA) of peri- and post-menopausal women. MATERIALS AND METHODS: Sexually active women in peri- (n = 29) and post-menopause (n = 54) suffering from VA, were progressively enrolled and treated for 30 days with PCV. Those wishing to continue (n = 73) were treated for additional 180 days. PCV was administered as one application twice a week. The vaginal health index (VHI; range 5 to 25) and the visual analogue score (VAS range for 0 to 100 mm for each item) for vaginal dryness, irritation, and pain at intercourse, along with the global symptoms score (GSS; range 1 to 15) and treatment safety, were evaluated at baseline and after 30 days. In those continuing the treatment an evaluation was performed after additional 180 days. RESULTS: Women in peri and post-menopause were of 48.7 ± 3.3 years and 57.5 ± 5.7 years old., respectively. At baseline all outcomes were significantly worse (p<0.002) in postmenopausal group, except the VHI (p < 0.056). After 30 days VHI increased (p < 0.001) of 4.1 ± 0.5 (mean ± SE), and 5.1 ± 0.4 in peri- and post-menopausal women respectively. VAS of vaginal dryness decreased (p < 0.001) of -24.4 ± 3.6, and -52.7 ± 2.6 (p < 0.001), VAS of irritation decreased (p<0.001) of -18.6 ± 4.4 and -47.8 ± 3.2, VAS of pain decreased (p < 0.001) of -26.2 ± 4.3 and -55.6 ± 3.1 and the GSS decreased (p < 0.001) of -3.9 ± 0.3, and -4.9 ± 0.2, in peri and post-menopausal women, respectively. All the modifications were significantly greater (p < 0.001)(p < 0.032 for GSS) in postmenopausal women, and after 30 days all outcomes were similar in the two groups of women. In comparison to baseline, after 210 days of treatment VHI increased of 7.7 ± 0.3 (p < 0.001), VAS of vaginal dryness decreased of -53.6 ± 1.9 (p < 0.001) VAS of irritation of -42.6 ± 1.4 (p < 0.001) VAS of pain of -46.7 ± 2.3 (p < 0.001) and the GSS of -6.5 ± 0.2 ± 0.2 (p < 0.001). All outcomes improved (p < 0.001) over the values observed after 30 days of treatment (p < 0.001). No side effect was reported. CONCLUSIONS: In peri- and post-menopausal women PCV administration rapidly improves VA symptoms, and its prolongation up to 6 months further increases its efficacy.

RESUMEN

OBJECTIVE: The aim of this study was to compare the efficacy of a non-hormone alternative, vaginal hyaluronic acid (HLA), to a standard-of-care therapy, vaginal estrogen, for the treatment of genitourinary syndrome of menopause (GSM). METHODS: This was a randomized, parallel arm pilot trial. Women with GSM were randomized to an HLA vaginal suppository or vaginal estrogen cream for 12 wk to compare the primary outcome, the vulvovaginal symptom questionnaire (VSQ) score. Secondary outcomes included the following: the female sexual function index (FSFI), the vaginal symptom index (VSI), visual analog scale (VAS) for dyspareunia, vaginal itching, and vaginal dryness, patient global impression of improvement (PGI-I) at follow-up, vaginal maturation index, and vaginal pH. Differences between treatment groups were estimated using the two-sided, two-sample t -test and 95% confidence intervals. RESULTS: Forty-nine women were randomized and 45 participants (vaginal estrogen = 23, vaginal HLA = 22) provided data at week 12. Baseline characteristics were similar in both groups. On the VSQ, there was no observed difference in overall scores between the HLA and vaginal estrogen groups at 12 wk ( P = 0.81). Improvement was seen within both treatment groups on the VSQ after 12 wk. The VAS score, total VSI score, total FSFI score, and vaginal pH improved over time; however, improvement did not differ between study arms. Over 90% participants noted improvement on the PGI-I in both groups ( P = 0.61). No treatment-related serious adverse events occurred. CONCLUSIONS: There were no clinically meaningful differences between vaginal HLA and vaginal estrogen for the treatment of GSM after 12 wk. Vaginal HLA may be a promising non-hormone therapy for GSM.

RESUMEN

BACKGROUND: Carrageenan-containing gels researched for the prevention of sexually transmitted infections (STIs) have shown promising results for human papillomavirus prevention in women, but not in men. We conducted a narrative review to assess the safety of these gels for genital use. METHODS: We searched PubMed using MeSH terms and keywords on 5 November 2023. Title/abstract of articles were screened to identify relevant ones. Full-text screening determined eligibility: empirical study evaluating safety of carrageenan-containing gel(s) for genital use. RESULTS: Of the 125 identified records, 15 were eligible, comprising 14 (10 randomised controlled trials and 4 cohorts) unique study populations. Studies included women only (n=11), men only (n=1) or both (n=3); number of participants ranged from 4 to 6202. Safety was assessed for vaginal (n=13), penile (n=3) and anal use (n=2). Most studies assessed safety of Carraguard (53%), followed by Divine9 (14%), and one each of iota-carrageenan gel, lambda-carrageenan gel, Carvir, PC-6500 (griffithsin and carrageenan) and PC-1005 (MIV-150/zinc acetate/carrageenan). Safety assessment relied on self-report (80.0%), testing for STIs (53.3%), investigator-identified genital findings (93.3%) and/or testing for changes in genital flora (60.0%). Adverse events (AEs) were described by investigators as mostly mild, (mostly) comparable between groups, not observed and/or not significant for vaginal and penile use. Only one study, assessing anal use of carrageenan, reported a significantly higher proportion of AEs in the carrageenan compared with placebo group. CONCLUSIONS: Carrageenan-based gels are generally well tolerated for vaginal and penile, but not anal use. Studies on carrageenan gel's safety for anal use are scarce.

RESUMEN

BACKGROUND: As the muscular and connective tissue components of the vagina are estrogen responsive, clinicians may recommend vaginal estrogen to optimize tissues preoperatively and as a possible means to reduce prolapse recurrence, but long-term effects of perioperative intravaginal estrogen on surgical prolapse management are uncertain. OBJECTIVE: This study aimed to compare the efficacy of perioperative vaginal estrogen vs placebo cream in reducing composite surgical treatment failure 36 months after native tissue transvaginal prolapse repair. STUDY DESIGN: This was an extended follow-up of a randomized superiority trial conducted at 3 tertiary US sites. Postmenopausal patients with bothersome anterior or apical vaginal prolapse were randomized 1:1 to 1-g conjugated estrogen cream (0.625 mg/g) or placebo, inserted vaginally twice weekly for ≥5 weeks preoperatively and continued twice weekly for 12 months postoperatively. All participants underwent vaginal hysterectomy (if the uterus was present) and standardized uterosacral or sacrospinous ligament suspension at the surgeon's discretion. The primary report's outcome was time to failure by 12 months postoperatively, defined by a composite outcome of objective prolapse of the anterior or posterior walls beyond the hymen or the vaginal apex descending below one-third the total vaginal length, subjective bulge symptoms, and/or retreatment. After 12 months, participants could choose to use-or not use-vaginal estrogen for atrophy symptom bother. The secondary outcomes included Pelvic Organ Prolapse Quantification points, subjective prolapse symptom severity using the Patient Global Impression of Severity and the Patient Global Impression of Improvement, and prolapse-specific subscales of the 20-Item Pelvic Floor Distress Inventory and the Pelvic Floor Impact Questionnaire-Short Form 7. Data were analyzed as intent to treat and "per protocol" (ie, ≥50% of expected cream use per medication diary). RESULTS: Of 206 postmenopausal patients, 199 were randomized, and 186 underwent surgery. Moreover, 164 postmenopausal patients (88.2%) provided 36-month data. The mean age was 65.0 years (standard deviation, 6.7). The characteristics were similar at baseline between the groups. Composite surgical failure rates were not significantly different between the estrogen group and the placebo group through 36 months, with model-estimated failure rates of 32.6% (95% confidence interval, 21.6%-42.0%) and 26.8% (95% confidence interval, 15.8%-36.3%), respectively (adjusted hazard ratio, 1.55; 95% confidence interval, 0.90-2.66; P=.11). The results were similar for the per-protocol analysis. Objective failures were more common than subjective failures, combined objective and subjective failures, or retreatment. Using the Patient Global Impression of Improvement, 75 of 80 estrogen participants (94%) and 72 of 76 placebo participants (95%) providing 36-month data reported that they were much or very much better 36 months after surgery (P>.99). These data included reports from 51 of 55 "surgical failures." Pelvic Organ Prolapse Quantification measurements, Patient Global Impression of Severity scores, and prolapse subscale scores of the 20-Item Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaire-Short Form 7 all significantly improved for both the estrogen and placebo groups from baseline to 36 months postoperatively without differences between the groups. Of the 160 participants providing data on vaginal estrogen usage at 36 months postoperatively, 40 of 82 participants (49%) originally assigned to the estrogen group were using prescribed vaginal estrogen, and 47 of 78 participants (60%) assigned to the placebo group were using vaginal estrogen (P=.15). CONCLUSION: Adjunctive perioperative vaginal estrogen applied ≥5 weeks preoperatively and 12 months postoperatively did not improve surgical success rates 36 months after uterosacral or sacrospinous ligament suspension prolapse repair. Patient perception of improvement remained very high at 36 months.

RESUMEN

Vaginal drug delivery is often preferred over systemic delivery to reduce side effects and increase efficacy in treating diseases and conditions of the female reproductive tract (FRT). Current vaginal products have drawbacks, including spontaneous ejection of drug-eluting rings and unpleasant discharge from vaginal creams. Here, we describe the development and characterization of a hypotonic, gel-forming, Pluronic-based delivery system for vaginal drug administration. The rheological properties were characterized with and without common hydrogel polymers to demonstrate the versatility. Both qualitative and quantitative approaches were used to determine the Pluronic F127 concentration below the critical gel concentration (CGC) that was sufficient to achieve gelation when formulated to be hypotonic to the mouse vagina. The hypotonic, gel-forming formulation was found to form a thin, uniform gel layer along the vaginal epithelium in mice, in contrast to the rapidly forming conventional gelling formulation containing polymer above the CGC. When the hypotonic, gel-forming vehicle was formulated in combination with a progesterone nanosuspension (ProGel), equivalent efficacy was observed in the prevention of chemically-induced preterm birth (PTB) compared to commercial Crinone® vaginal cream. Further, ProGel showed marked benefits in reducing unpleasant discharge, reducing product-related toxicity, and improving compatibility with vaginal bacteria in vitro. A hypotonic, gel-forming delivery system may be a viable option for therapeutic delivery to the FRT.

RESUMEN

AIMS: The current work describes the development of mechanistic vaginal absorption and metabolism model within Simcyp Simulator to predict systemic concentrations following vaginal application of ring and gel formulations. METHODS: Vaginal and cervix physiology parameters were incorporated in the model development. The study highlights the model assumptions including simulation results comparing systemic concentrations of 5 different compounds, namely, dapivirine, tenofovir, lidocaine, ethinylestradiol and etonogestrel, administered as vaginal ring or gel. Due to lack of data, the vaginal absorption parameters were calculated based on assumptions or optimized. The model uses release rate/in vitro release profiles with formulation characteristics to predict drug mass transfer across vaginal tissue into the systemic circulation. RESULTS: For lidocaine and tenofovir vaginal gel, the predicted to observed AUC0-t and Cmax ratios were well within 2-fold error limits. The average fold error (AFE) and absolute AFE indicating bias and precision of predictions range from 0.62 to 1.61. For dapivirine, the pharmacokinetic parameters are under and overpredicted in some studies due to lack of formulation composition details and relevance of release rate used in ring model. The predicted to observed AUC0-t and Cmax ratios were well within 2-fold error limits for etonogestrel and ethinylestradiol vaginal ring (AFEs and absolute AFEs from 0.84 to 1.83). CONCLUSION: The current study provides first of its kind physiologically based pharmacokinetic framework integrating physiology, population and formulation data to carry out in silico mechanistic vaginal absorption studies, with the potential for virtual bioequivalence assessment in the future.

RESUMEN

BACKGROUND: Despite the gold standard treatment for genitourinary syndrome of menopause (GSM) is based on the use of local or systemic estrogen-containing products, the typical long-term side effects of hormonal treatments and, most importantly, the contraindications in patients with history of breast and endometrial neoplasms do limit in some extent its use. As hyaluronic acid and some highly purified botanicals have clearly demonstrated their anti-inflammatory and mucosa-protecting properties, we have tested, in women with GSM, a class II vaginal medical device containing hyaluronate gel and a mucoadhesive active enriched with purified alkylamides from Zanthoxylum bungeanum, triterpenes from Centella asiatica and high molecular weight polysaccharides from Tamarindus indica. METHODS: Our single-center, open-label, prospective and observational study was conducted on 50 menopausal women enrolled at the Department of Maternal-Fetal Medicine at Umberto I Polyclinic Hospital in Rome, Italy. Gel administration lasted 150 days and was performed daily for the first 12 days and every 48 hours for the remaining 138 days. Clinical evaluations were performed at baseline and after 12, 57 and 150 days. Besides product safety, main outcomes of our study were: 1) vaginal health (by Vaginal Health Index score [VHI]); 2) sexual quality of life (by Female Sexual Distress Scale [FSDS]); and 3) percentage of women declaring regular sexual activity. RESULTS: The product was safe with no specific adverse events reported. It significantly improved VHI (about 5% after 57 days and 8% after 150 days), FSDS (about 7% after 57 days and 10% after 150 days), and sexual activity (about 20% after 150 days). It also reduced dryness, dyspareunia, burning, itching, and dysuria incidence, respectively by about 18%, 14%, 14%, 27% and 11% after 150 days. CONCLUSIONS: In women with GSM, the intravaginal administration of a hyaluronate-based gel enriched with purified botanical actives endowed with anti-inflammatory and mucosal-protecting properties, reduced painful sensation during sexual acts and increased regular sexual activity.

RESUMEN

Importance: Surgical repairs of apical/uterovaginal prolapse are commonly performed using native tissue pelvic ligaments as the point of attachment for the vaginal cuff after a hysterectomy. Clinicians may recommend vaginal estrogen in an effort to reduce prolapse recurrence, but the effects of intravaginal estrogen on surgical prolapse management are uncertain. Objective: To compare the efficacy of perioperative vaginal estrogen vs placebo cream on prolapse recurrence following native tissue surgical prolapse repair. Design, Setting, and Participants: This randomized superiority clinical trial was conducted at 3 tertiary US clinical sites (Texas, Alabama, Rhode Island). Postmenopausal women (N = 206) with bothersome anterior and apical vaginal prolapse interested in surgical repair were enrolled in urogynecology clinics between December 2016 and February 2020. Interventions: The intervention was 1 g of conjugated estrogen cream (0.625 mg/g) or placebo, inserted vaginally nightly for 2 weeks and then twice weekly to complete at least 5 weeks of application preoperatively; this continued twice weekly for 12 months postoperatively. Participants underwent a vaginal hysterectomy (if uterus present) and standardized apical fixation (either uterosacral or sacrospinous ligament fixation). Main Outcomes and Measures: The primary outcome was time to failure of prolapse repair by 12 months after surgery defined by at least 1 of the following 3 outcomes: anatomical/objective prolapse of the anterior or posterior walls beyond the hymen or the apex descending more than one-third of the vaginal length, subjective vaginal bulge symptoms, or repeated prolapse treatment. Secondary outcomes included measures of urinary and sexual function, symptoms and signs of urogenital atrophy, and adverse events. Results: Of 206 postmenopausal women, 199 were randomized and 186 underwent surgery. The mean (SD) age of participants was 65 (6.7) years. The primary outcome was not significantly different for women receiving vaginal estrogen vs placebo through 12 months: 12-month failure incidence of 19% (n = 20) for vaginal estrogen vs 9% (n = 10) for placebo (adjusted hazard ratio, 1.97 [95% CI, 0.92-4.22]), with the anatomic recurrence component being most common, rather than vaginal bulge symptoms or prolapse repeated treatment. Masked surgeon assessment of vaginal tissue quality and estrogenization was significantly better in the vaginal estrogen group at the time of the operation. In the subset of participants with at least moderately bothersome vaginal atrophy symptoms at baseline (n = 109), the vaginal atrophy score for most bothersome symptom was significantly better at 12 months with vaginal estrogen. Conclusions and Relevance: Adjunctive perioperative vaginal estrogen application did not improve surgical success rates after native tissue transvaginal prolapse repair. Trial Registration: ClinicalTrials.gov Identifier: NCT02431897.

RESUMEN

HIV pre-exposure prophylaxis (PrEP) is dominated by clinical therapeutic antiretroviral (ARV) drugs. Griffithsin (GRFT) is a non-ARV lectin with potent anti-HIV activity. GRFT's preclinical safety, lack of systemic absorption after vaginal administration in animal studies, and lack of cross-resistance with existing ARV drugs prompted its development for topical HIV PrEP. We investigated safety, pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of PC-6500 (0.1% GRFT in a carrageenan (CG) gel) in healthy women after vaginal administration. This randomized, placebo-controlled, parallel group, double-blind first-in-human phase 1 study enrolled healthy, HIV-negative, non-pregnant women aged 24-45 years. In the open label period, all participants (n = 7) received single dose of PC-6500. In the randomized period, participants (n = 13) were instructed to self-administer 14 doses of PC-6500 or its matching CG placebo (PC-535) once daily for 14 days. The primary outcomes were safety and PK after single dose, and then after 14 days of dosing. Exploratory outcomes were GRFT concentrations in cervicovaginal fluids, PD, inflammatory mediators and gene expression in ectocervical biopsies. This trial is registered with ClinicalTrials.gov, number NCT02875119. No significant adverse events were recorded in clinical or laboratory results or histopathological evaluations in cervicovaginal mucosa, and no anti-drug (GRFT) antibodies were detected in serum. No cervicovaginal proinflammatory responses and no changes in the ectocervical transcriptome were evident. Decreased levels of proinflammatory chemokines (CXCL8, CCL5 and CCL20) were observed. GRFT was not detected in plasma. GRFT and GRFT/CG in cervicovaginal lavage samples inhibited HIV and HPV, respectively, in vitro in a dose-dependent fashion. These data suggest GRFT formulated in a CG gel is a safe and promising on-demand multipurpose prevention technology product that warrants further investigation.

RESUMEN

INTRODUCTION: In puerperium, the hypoestrogenic state induced by delivery and subsequently sustained by lactation may lead to vaginal dryness, burning, and itching sensation, contributing to the onset of sexual dysfunction. MATERIAL AND METHODS: This was a prospective, randomized, controlled, open-label study (NCT04560283) for evaluating the effects of application of a prolonged-release hyaluronic acid derivative vaginal gel in restoring sexual function during the postpartum period. Eighty-five patients were randomized to apply prolonged-release Hydeal-D 0.2% vaginal gel (Fidia Farmaceutici, Abano Terme, Italy; n = 43) every three days for 12 consecutive weeks or expectant management (n = 42). RESULTS: Women undergoing treatment had a more elevate increase in Female Sexual Function Index (FSFI) total score (+15.1 ± 11.9 vs +6.5 ± 8.9, p < 0.001) and a higher decrease in vaginal pH (-1.2 ± 0.7 vs -0.2 ± 1.1; p < 0.001). Moreover, the proportion of vaginal smears with maturation index (VMI) >65 was significantly higher in patients treated (80.6% vs 35.3%; p = 0.004). Edinburgh Postnatal Depression Scale (EPDS) decreased significantly in both groups with no inter-group difference (p = 0.459). Only two cases (4.8%) of moderate vaginal burning sensation were reported in patients undergoing local vaginal therapy. CONCLUSIONS: The results of our study demonstrated that hyaluronic acid derivative vaginal gel (Hydeal-D) was able to improve sexual function of puerperal women in the short-term treatment.KEY MESSAGEIn the puerperium, the hypoestrogenic state induced by delivery and subsequently sustained by lactation may lead to vaginal dryness, burning, and itching sensation, contributing to the onset of sexual dysfunction.Hydeal-D is a prolonged-release hyaluronic acid derivative characterised by elevated resistance to enzymatic breakdown. During puerperium, its local application may improve the vaginal microenvironment by ensuring a better migration and proliferation of cells involved in local tissue repair.Among puerperal women, Hydeal-D vaginal gel causes a significant improvement of sexual function, including desire, arousal, and lubrification, compared to expectant management. Furthermore, it leads to a decrease in vaginal pH and an increase of the trophic status of vaginal epithelium.

RESUMEN

Although sensory-guided product design is most traditionally used by food and beverage companies, the approach has widespread application for many other products, including pharmaceuticals and medical devices. Previously, our team used sensory methods to explore preclinical optimization of soft-gel vaginal microbicides. Past clinical trials suggest vaginal microbicides may be an effective means for women to protect themselves from HIV and other sexually transmitted infections, but these microbicides will not work if they are not used due to poor acceptability. Our prior work suggests properties like firmness, size, and shape all influence women's willingness to try soft-gel vaginal suppositories. As product insertion is part of the overall experience of using vaginal microbicides, understanding the features of vaginal applicators that appeal to women, and incorporating these insights into vaginal drug delivery systems, may also improve user adherence. Despite widespread use of vaginal applicators, there is minimal public data on women's perceptions of and preferences for physical applicator features. Other work suggests women want vaginal applicators that are single use, pre-filled, made of plastic, and easy to use, store, and discard. Applicator attributes that may be important to women, such as length, color, or visual appeal, have not been investigated previously. The objective of this research was to understand what physical applicator attributes are appealing to women. Here, 18 commercially available applicators were evaluated by a convenience sample of women (n = 102) for overall liking and perceptions of various attributes (perceived length and width, ease-of-grip, expected ease-of-use, expected comfort inside the body, visual appeal, color liking, and environmental friendliness). Preference mapping using both liking data and attribute data showed attributes such as color, visual appeal, ease of grip, expected ease of use, and expected comfort inside the body drove higher liking ratings for applicators, while perceived length negatively affected liking. In general, plastic tampon applicators contained more positive features and were better liked relative to a cardboard tampon applicator or applicators for insertion of medicated gels or suppositories. Incorporating more desirable features into applicators meant for insertion of vaginal microbicides or other vaginal medications may improve the user experience, and possibly user adherence.

RESUMEN

AIM OF THE STUDY: Vaginal atrophy is of the most common problems during menopause with significant psychosocial and medical consequences. Estrogen as an approved therapy for vaginal atrophy can be associated with adverse effects and several contraindications in menopause patients. The aim is to compare the effect of Aloe Vera vaginal cream with commercially available estrogen vaginal cream for management of vaginal atrophy in menopause females. MATERIALS AND METHODS: This is a double-blinded randomized controlled trial on 60menopause female with complaints of vaginal atrophy symptoms. Subjects were randomly allocated in two groups of 30 patients, named as estrogen and Aloe Vera groups. Vaginal health index (VHI), maturity value (MV), vaginal cytologic smear, transvaginal sonography (TVS) and severity of symptoms related to vaginal atrophy were assessed before and after 6-weeks of vaginal cream administration. RESULTS: Comparison of MV before and after treatment revealed that superficial cells were significantly increased after administration of both vaginal cream (6.67 VS 54.33 in Aloe Vera group; 4.33 VS 59.67 in estrogen group). In addition, VHI (13.83 vs 20.13 in Aloe Vera group; 13.97 vs 19.93 in estrogen group) and symptoms of vaginal atrophy (3.63 vs 1.10 in Aloe Vera group; 3.90 vs 0.66 in estrogen groups) were also significantly improved after treatment in both groups. There was no significant difference between groups after treatment except for fluid volume with a superiority in Aloe Vera group (P-value = 0.004) CONCLUSION: Aloe Vera vaginal cream can be as effective as estrogen vaginal cream in the management of vaginal atrophy in menopause females.

RESUMEN

Context: In Persian medicine, topical ingredients such as Rosa damascena Mill. (Rosaceae), are usually recommended for the treatment of uterine diseases. Scientific evaluation of these historical documents can be valuable for finding new potential use in conventional medicine.Objective: This clinical trial was performed to determine whether the use of the 'ward' vaginal tablet, which contains Rosa damascena, Punica granatum L. (Punicaceae), Querqus infectoria Oliv. (Fagaceae), Myrtus communis L. (Myrtaceae) and Nardostachys jatamansi (D.Don) DC. (Caprifoliaceae) could alleviate the symptoms of vulvovaginal candidiasis.Materials and methods: A parallel double-blinded placebo-controlled study was done. Eighteen to fifty-year-old women with vulvovaginal candidiasis were divided into the 'ward' and placebo groups, 46 individuals in each group. The 'ward' group received the 'ward' vaginal tablet containing 200 mg of dried extract. Placebo group received a placebo (composed of corn starch and lactose). One tablet was applied through the vagina for 7 consecutive nights.Results: Two weeks after medication administration, the vaginal discharge sample of patients was re-cultured; 29 patients (63.045%) in the 'ward' group and 6 (13.04%) patients in the placebo group had negative culture (p < 0.001). All clinical symptoms including itching, irritation, and vaginal discharge were significantly reduced in the 'ward' group compared with the placebo group following the intervention and the follow up (p < 0.05).Discussion and conclusions: The findings suggest the 'ward' vaginal tablet could ameliorate vulvovaginal candidiasis. Future larger studies are recommended due to compare the therapeutic effect of the 'ward' vaginal tablet with common treatments.

RESUMEN

RATIONALE: Voiding difficulty is more common in males, although it is not uncommon in females. Female voiding difficulty can be caused by iatrogenic, anatomic, and neurogenic factors, and specifically urethra stricture, impaired detrusor contractility, primary bladder neck obstruction, and detrusor-external sphincter dyssynergia. Labial adhesion is a rare cause of female voiding difficulty.The incidence of labial fusion has been reported to be 0.6% to 1.4% in children; however, the incidence in the elderly has yet to be fully elucidated. PATIENT CONCERNS: We present the case of a postmenopausal and sexually inactive 76-year-old female patient who had nearly total vaginal and urethral occlusion due to labial adhesion. She had no underlying diseases and came to our clinic with a 10-month history of voiding difficulty, postmicturition dribbling, and involuntary urinary leakage when getting up. DIAGNOSIS: A genital examination revealed nearly total fusion of the labia minor with only a 3-mm pinhole opening at the posterior end. INTERVENTIONS: Treatment included surgical separation, the local application of estrogen cream, and self-dilatation. She also received an antimuscarinic agent to treat overactive bladder secondary to bladder outlet obstruction which was caused by labial adhesion. OUTCOMES: No surgical complications occurred. Moreover, no labial adhesion or voiding dysfunction was found immediately after the surgery or after 6 months of follow-up. LESSONS SUBSECTIONS: Genital examinations are a basic but very important noninvasive skill for physicians. This case report highlights that genital examinations should be a priority for patients with gynecological or urological symptoms.

RESUMEN

OBJECTIVE: To assess the efficacy of non-hormonal, hyaluronic acid (HLA)-based vaginal gel in improving vulvovaginal estrogen-deprivation symptoms in women with a history of endometrial cancer. METHODS: For this single-arm, prospective, longitudinal trial, we enrolled disease-free women with a history of endometrial cancer who underwent surgery (total hysterectomy) and postoperative radiation. Participants used HLA daily for the first 2 weeks, and then 3×/week until weeks 12-14; dosage was then increased to 5×/week for non-responders. Vulvovaginal symptoms and pH were assessed at 4 time points (baseline [T1]; 4-6 weeks [T2]; 12-14 weeks [T3]; 22-24 weeks [T4]) with clinical evaluation, the Vaginal Assessment Scale (VAS), Vulvar Assessment Scale (VuAS), Female Sexual Function Index (FSFI), and Menopausal Symptom Checklist (MSCL). RESULTS: Of 43 patients, mean age was 59 years (range, 38-78); 54% (23/43) were partnered; and 49% (21/43) were sexually active. VAS, VuAS, MSCL, and SAQ (Sexual Activity Questionnaire) scores significantly improved from baseline to each assessment point (all p < .002). FSFI total mean scores significantly increased from T1 to T2 (p < .05) and from T1 to T4 (p < .03). At T1, 41% (16/39) felt confident about future sexual activity compared to 68% (17/25) at T4 (p = .096). Severely elevated vaginal pH (>6.5) decreased from 30% (13/43) at T1 to 19% (5/26) at T4 (p = .41). CONCLUSION: The HLA-based gel improved vulvovaginal health and sexual function of endometrial cancer survivors in perceived symptoms and clinical exam outcomes. HLA administration 1-2×/week is recommended for women in natural menopause; a 3-5×/week schedule appears more effective for symptom relief in cancer survivors.

RESUMEN

BACKGROUND: Around 90% of postmenopausal women are suffering from vaginal atrophy. This study aimed to evaluate the effect of oxytocin vaginal gel on vaginal atrophy among postmenopausal women. METHODS: This was a randomized controlled trial that was conducted on 96 postmenopausal women who suffered from vaginal atrophy. The inclusion criteria were: literate women, age 40-60, at least 1 year passed from their last menstrual period or the level of FSH > 40 IU, monogamous women with the sexual relationship. Women in the intervention group, requested to use one applicator of 400 IU oxytocin gel per night and women in the placebo group used placebo each night. The subjective symptoms of vaginal atrophy, vaginal PH, maturation index were measured before and after the intervention. RESULTS: The number of superficial cells was increased significantly in the oxytocin group compared to placebo (38.7 ± 7.18 vs. 3.69 ± 2.76, p = 0.0001), while the number of parabasal cells was decreased significantly in the oxytocin compared to placebo after the intervention. The improvement of the maturation index was more dominant in the oxytocin group (increased from 7.76 ± 4.68 to 52.48 ± 7.54) in comparison to the placebo group (increased from 8.58 ± 4.35 to 13.25 ± 5.06). The PH of the vagina decreased significantly in the oxytocin group in comparison to the placebo group (p = 0.0001). After 8 weeks, 88.6 and 7.1% of women in the oxytocin and placebo groups did not show the severe symptoms of vaginal atrophy (p = 0.001). CONCLUSION: The results of this study showed that eight- week intervention with oxytocin vaginal gel (400 IU) could significantly improve the vaginal maturation index, subjective symptoms of vaginal atrophy and reduce the PH of the vagina. Using this medication in women who have a contraindication for hormone therapy is recommended. TRIAL REGISTRATION: IRCT20160602028220N2.
