Abstract
BACKGROUND Vulvodynia is a chronic pain condition without an identifiable cause. As such, it is a diagnosis of exclusion, and all other causes of vulvar pain should be excluded. Although a standard treatment for vulvodynia has not been established yet, multidisciplinary care programs appear to be effective. PUROPOSE The aim of this retrospective monocentric study was to analyze the prevalence of vulvodynia among women referred to our institution for a suspected diagnosis and to evaluate the efficacy of a multidimensional treatment plan. The primary outcome was the prevalence of vulvodynia following differential diagnosis. Secondary outcomes included: prevalence of the differential diagnoses, symptom resolution rate following treatment, and the relation between persistence of symptoms and (a) patients' age; (b) coexisting chronic overlapping pain conditions (COPCs). RESULTS After having ruled out all other causes of vulvar pain, only 40.1% of women were considered as affected by vulvodynia. The most frequent differential diagnoses included lower genital tract infections (25.3%), vulvar lichen sclerosus (17.6%) and vulvovaginal atrophy (8.2%). Following a multidisciplinary care program, resolution of symptoms was observed in 13.6% cases, improvement in 64.3% and persistence in 21.9%. We did not find a statistically significant association between persistence of symptoms and age > 38 years (OR 2.10; p = 0.30). Women with one or more COPCs other than vulvodynia had a 75% increased risk of not obtaining a resolution of symptoms (OR 1.75; p = 0.44). CONCLUSION A thorough differential diagnosis and a multidisciplinary care program may represent a first way out of the muddle in the management of these patients.

Abstract
Vaginitis is the presenting symptom at millions of office visits each year in the United States. Although treatment of sporadic cases is often straightforward, recurrent cases present both diagnostic and treatment challenges. Molecular diagnostic tests are likely superior to in-office microscopy for most clinicians and most cases. In both recurrent bacterial vaginosis and recurrent vulvovaginal candidiasis, national treatment guidelines recommend an extended treatment duration with one of the first-line agents. In cases in which such treatment is not successful, vaginal boric acid is likely the cheapest and easiest alternative option. New antifungal medications offer additional but limited treatment options. Probiotics are not recommended for prevention of vulvovaginal candidiasis; however, vaginal products containing Lactobacillus crispatus may have promise for recurrent bacterial vaginosis. Trichomoniasis should be treated with a 1-week course of metronidazole; this is the only sexually transmitted infection for which treatment recommendations vary by sex. In cases in which patients do not respond to initial treatment, the diagnosis should be reconsidered, and other potential causes such as desquamative inflammatory vaginitis, genitourinary syndrome of menopause, or vulvodynia should be considered.

Abstract
INTRODUCTION Sexual pain has a profound impact on individuals, regardless of their sexual orientation or gender identity, and affects women more often than men. It adversely affects both sexual function and interpersonal relationships. Despite its prevalence, sexual pain in women often remains unaddressed and untreated. Various underlying causes contribute to sexual pain, sometimes involving multiple factors. We explore treatment options and offer clinical insights into the evaluation and management of 4 common conditions which cause sexual pain in women. In this article, we use the term "women" to indicate cisgender women. OBJECTIVES Our aim is to highlight the most common clinical scenarios of sexual pain and provide comprehensive discussions on each, to improve patient care and outcomes in the management of sexual pain. METHODS We conducted a comprehensive review of literature and clinical cases to explore the various causes and management strategies for sexual pain in women. We systematically searched databases such as PubMed, Google Scholar, and relevant medical journals. We included peer-reviewed articles, case studies, and clinical trials published between 2000 and 2023. Additionally, we analyzed real-life cases from our clinical practice at our academic institution. RESULTS Our review identified various factors contributing to sexual pain in women, ranging from hormonal imbalances to neuroproliferative and inflammatory conditions affecting the genitourinary system. Each case should be approached individually to offer optimal management strategies accordingly. CONCLUSION The management of sexual pain in women requires a comprehensive approach that addresses the multifactorial nature of the condition. Patient education and counseling play a crucial role in the management of sexual pain, empowering individuals to advocate for their own health and well-being. The collaboration between healthcare providers and patients can improve our understanding and management of this complex condition.

Abstract
Using a novel data-driven network approach, this study aimed to examine the interconnection between the key elements of the Fear-Avoidance Model of female genital pain - sexual arousal, fear-avoidant cognitions, and motivational coping - and its associated factors to predict the intensity and frequency of genital pain across women over time. Network modeling allowed for a comprehensive evaluation of the Fear-Avoidance model while capturing the dynamic features of genital pain. We estimated a cross-sectional and a temporal, contemporaneous, and between-persons network model on convenience-based data of 543 female students (mean age = 23.7 years, SD = 3.6) collected at three time points. Results showed that lubrication, pain catastrophizing, pain avoidance, fear-avoidance beliefs, sexual satisfaction, anxiety, and frequency of coital and non-coital sex predicted pain, with lubrication being the most consistent predictor across estimations. The network of women with recurrent genital pain showed a similar pattern as the network of the total sample, except that pain avoidance and fear-avoidance beliefs rather than pain catastrophizing predicted pain directly, and frequency of coital and non-coital sexual activities played a more prominent role. These results suggest that the main problem of genital pain centers around women not being sufficiently aroused during intercourse and inadequate ways of pain coping, which are critical targets of cognitive-behavioral therapy treatment and should be developed further.

Abstract
INTRODUCTION Lichen sclerosus (LS) is an inflammatory skin disease affecting all ages. LS typically involves the anogenital site where it causes itching and soreness; it may lead to sexual and urinary dysfunction in females and males; however, it may be asymptomatic. First signs of LS are usually a whitening of the genital skin, sometimes preceded by redness and oedema; fissuring, scarring, shrinkage and fusion of structures may follow in its course. LS is associated with an increased risk of genital cancer. LS has a huge impact on the quality of life of affected patients, and it is important to raise more awareness of this not uncommon disease in order to diagnose and treat it early. OBJECTIVES The guideline intends to provide guidance on the diagnostic of LS (part 1), highlight important aspects in the care of LS patients, generate recommendations and treatment algorithms (part 2) on topical, interventional and surgical therapy, based on the latest evidence, provide guidance in the management of LS patients during pregnancy, provide guidance for the follow-up of patients with LS and inform about new developments and potential research aspects. MATERIALS AND METHODS The guideline was developed in accordance with the EuroGuiDerm Methods Manual v1.3 https://www.edf.one/de/home/Guidelines/EDF-EuroGuiDerm.html. The wording of the recommendations was standardized (as suggested by the GRADE Working Group). The guideline development group is comprised of 34 experts from 16 countries, including 5 patient representatives. RESULTS Ultrapotent or potent topical corticosteroids in females and males, adults and children remain gold standard of care for genital LS; co-treatment with emollients is recommended. If standard treatment fails in males, a surgical intervention is recommended, complete circumcision may cure LS in males. UV light treatment is recommended for extragenital LS; however, there is limited scientific evidence. Topical calcineurin inhibitors are second line treatment. Laser treatment, using various wave lengths, is under investigation, and it can currently not be recommended for the treatment of LS. Treatment with biologics is only reported in single cases. CONCLUSIONS LS has to be diagnosed and treated as early as possible in order to minimize sequelae like scarring and cancer development. Topical potent and ultrapotent corticosteroids are the gold standard of care; genital LS is often a lifelong disease and needs to be treated long-term.

Abstract
Introduction Localized provoked vulvodynia (LPV) is a prevalent sexual health condition with significant negative impacts on quality of life. There is a lack of consensus regarding effective management. Methods We used Arksey and O'Malley's five-step method to identify, collate, and evaluate literature published between 2010 and 2023. The scoping review investigated the efficacy or effectiveness of interventions in the management of LPV. The aim of this paper is to map the literature on the efficacy or effectiveness of physical interventions. Results The review produced 19 primary studies of physical interventions for LPV. These include acupuncture, laser therapy, physiotherapy, transcutaneous electrical nerve stimulation, low-intensity shockwave therapy, transcranial direct current stimulation, and vestibulectomy. Conclusion Published studies that investigated a range of physical treatments for LPV showed some positive effects, except for transcranial direct-current stimulation. The remaining modalities demonstrated improved sexual pain and treatment satisfaction, when measured. Findings were mixed for non-sexual pain. There was insufficient evidence to draw conclusions regarding other outcomes. Researchers are encouraged to conduct larger, high-quality studies that sample more diverse patient populations and use patient-oriented outcomes to assess effectiveness of physical modalities.

Abstract
BACKGROUND Vulvodynia (VVD) is a debilitating chronic vulvar pain significantly affecting patients' quality of life. Interstitial cystitis/bladder pain syndrome (IC/BPS) is a chronic and complex illness characterized by an unpleasant sensation related to the filling of the bladder and it strongly impacts patients' lives. The exact mechanisms of the two syndromes remain unknown, but there is an overlap between suspected pathophysiologies. OBJECTIVE To present an overview of the current research on the association between VVD and IC/BPS. SEARCH STRATEGY A systematic search of three electronic databases was conducted. Studies examining the correlation between VVD and IC/BPS with male and female patients aged over 18 years were included. SELECTION CRITERIA Studies assessing the coexistence of VVD and IC/BPS were included. Reviews, letters to the editor, conference abstracts, book chapters, guidelines, Cochrane reviews, and expert opinions were excluded. DATA COLLECTION AND ANALYSIS Two reviewers screened the studies for eligibility. Eligible studies were screened for quality. MAIN RESULTS A total of 13 studies were included in the final review. Among them, 11 presented a positive association between the two syndromes. The studies highlighted that VVD and IC/BPS share common comorbidities and possibly etiopathogenic pathways. CONCLUSION VVD and IC/BPS are both complex and multifactorial syndromes. This review highlights an association between them, but additional studies on the topic should be conducted for a more precise conclusion.

Abstract
Chronic primary pain conditions (CPPCs) affect over 100 million Americans, predominantly women. They remain ineffectively treated, in large part because of a lack of valid animal models with translational relevance. Here, we characterized a CPPC mouse model that integrated clinically relevant genetic (catechol-O-methyltransferase; COMT knockdown) and environmental (stress and injury) factors. Compared with wild-type mice, Comt+/- mice undergoing repeated swim stress and molar extraction surgery intervention exhibited pronounced multisite body pain and depressive-like behavior lasting >3 months. Comt+/- mice undergoing the intervention also exhibited enhanced activity of primary afferent nociceptors innervating hindpaw and low back sites and increased plasma concentrations of norepinephrine and pro-inflammatory cytokines interleukin-6 (IL-6) and IL-17A. The pain and depressive-like behavior were of greater magnitude and longer duration (≥12 months) in females versus males. Furthermore, increases in anxiety-like behavior and IL-6 were female-specific. The effect of COMT genotype × stress interactions on pain, IL-6, and IL-17A was validated in a cohort of 549 patients with CPPCs, demonstrating clinical relevance. Last, we assessed the predictive validity of the model for analgesic screening and found that it successfully predicted the lack of efficacy of minocycline and the CB2 agonist GW842166X, which were effective in spared nerve injury and complete Freund's adjuvant models, respectively, but failed in clinical trials. Yet, pain in the CPPC model was alleviated by the beta-3 adrenergic antagonist SR59230A. Thus, the CPPC mouse model reliably recapitulates clinically and biologically relevant features of CPPCs and may be implemented to test underlying mechanisms and find new therapeutics.

Abstract
Superwoman Schema, a conceptual framework that reflects Black women's ability to overcome gendered racism and stress, affects the way Black women choose to cope with health-related issues. The purpose of this study was to investigate how Black women perceive they should cope with sexual pain using the Superwoman Schema as an analytic and interpretative guide. Data were derived from participants who completed an individual interview on sexual pain and pleasure. Deductive thematic analysis was conducted. Results indicated whereas some Black women endorsed all five components of Superwoman Schema as coping strategies for sexual pain, other Black women resisted SWS completely. Additionally, one participant was an outlier and did not endorse or resist SWS. Implications for generational sexual health interventions for Black women are discussed.

Abstract
OBJECTIVE The main objective of this review was to develop strategies for individualizing multidisciplinary therapy for vulvodynia. METHODS We conducted two literature searches; the first one focused on clinical trials assessing vulvodynia treatments published after the recommendations of the expert committee of the Fourth International Consultation on Sexual Medicine. The second search targeted studies identifying predictive factors and mediators of vulvodynia treatments, published from the earliest date to October 2022. RESULTS Based on data from 55 relevant studies, we developed models of individualized multidisciplinary therapy targeting groups of women less responsive to multidisciplinary therapy (characterized by women with higher vulvar pain intensity, impaired sexual functioning, and vulvodynia secondary subtype) and to physical therapy, as an isolated treatment (characterized by women with increased pelvic floor muscle tone and vulvodynia primary subtype). Each individualized multidisciplinary therapy model comprises three components: psychotherapy, medical care, and physical therapy. These components provide distinct therapeutic modalities for distinct subgroups of women with vulvodynia; the women subgroups were identified according to the characteristics of women, the disease, partners, and relationships. Additionally, for women with provoked vestibulodynia who exhibit less benefits from vestibulectomy (such as those with higher levels of erotophobia, greater vulvar pain intensity, and the primary subtype) and encounter resistance to individualized multidisciplinary therapy, we suggest additional conservative treatments before performing vestibulectomy. CONCLUSION Our study is a pioneer in the development of models that allow the individualization of multidisciplinary therapy for vulvodynia and represents a significant advance in the clinical practice of gynecologists, physiotherapists, and psychologists.

Abstract
The etiology of idiopathic pain conditions, such as Provoked vulvodynia (PV), is multifactorial. The efficiency of venlafaxine, serotonin-noradrenaline reuptake inhibitor (SNRIs) in modulating vulvar pain led to the hypothesis that PV might involve central mechanisms. Here, we investigate whether vulvar pain is associated with gene-expression changes in mood, stress and pain systems, including amygdala (Amg), medial prefrontal cortex (mPFC), and periaqueductal gray matter (PAG). Additionally, we examined the analgesic and anxiolytic effects of venlafaxine. We found that the development of chronic vulvar pain in an animal model of PV is associated by overexpression of genes related to neuronal-activity and neuroinflammation in the Amg, mPFC, and PAG. Additionally, changes in the expression of GABA and serotonin synthesis, and reuptake were noted in the Amg and mPFC. Unsurprisingly, anxiety-like behavior and emotional-disorder were observed in rats with chronic vulvar pain. Nevertheless, treatment with venlafaxine (37.5 mg/kg) for one month significantly improves the vulvar hypersensitivity, as well as reduces the anxiety level. More critically, the long-term gene expression adaptation in serotonin receptor and synthesis, GABA synthesis, neuroplasticity, and neuroinflammation in the Amg, mPFC, and PAG, were modulated by venlafaxine in rats with vulvar pain. Our findings suggest that vulvar hypersensitivity induced by inflammation might associated with gene expression changes in brain areas that are involved in mood, stress and pain regulation. These changes probably play a role in central sensitization, and anxiety. Strikingly, enhancing the activity of serotonin and noradrenaline via venlafaxine treatment in rats with vulvar pain induces analgesic and anxiolytic effects.

Multimodal and Interdisciplinary Interventions for the Treatment of Localized Provoked Vulvodynia: A Scoping Review of the Literature from 2010 to 2023. Int J Womens Health 2024; 16:55-94. [PMID: 38250180 PMCID: PMC10798054 DOI: 10.2147/ijwh.s436222] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Accepted: 12/13/2023] [Indexed: 01/23/2024] Open
Abstract
Introduction Localized provoked vulvodynia (LPV) is a chronic condition characterized by pain in the vulvar vestibule, which can be provoked by pressure or touch and which is not tied to a clear underlying cause. Research into the etiology of and most appropriate treatment strategy for LPV is still limited. Methods Using Arksey and O'Malley's model for scoping reviews, we evaluated the research question: what is the current evidence regarding the efficacy/effectiveness of multimodal or interdisciplinary interventions for the treatment of LPV? We collated and analyzed articles from 2010 to 2023 to capture the current research landscape. Results Our review identified 27 studies, which either compared treatments between classes (eg pharmacologic versus psychologic modalities) or described interdisciplinary treatment programs. We identify several trends in the literature. First, outcome measures are inconsistent between studies, often unvalidated, and may not adequately mirror patient concerns. Second, the absence of appropriate comparator groups in many studies restricts providers' ability to appraise which treatments may be most efficacious. Third, selection bias and demographic homogeneity limit generalizability. Finally, we highlight the need for head-to-head trials of vestibulectomy with other treatments considered first line for vulvodynia management. Conclusion There is insufficient evidence to suggest the superiority of one treatment modality for LPV relative to others or to recommend a particular interdisciplinary management strategy. Future research should use a head-to-head design where sham control is impossible, incorporate patient-centered outcome measures, and investigate impacts of treatment among diverse samples of LPV patients.

Abstract
INTRODUCTION Vulvodynia is defined as vulvar pain of at least 3 months' duration, without clear identifiable cause, which may have potential associated factors. It can have a significant impact on women's quality of life due to a combination of physical pain, emotional distress, and limited treatment options. Despite affecting a considerable number of women worldwide, the causes and underlying mechanisms of vulvodynia remain poorly understood. Given the recognized association of the vaginal microbiota with various gynecologic disorders, there has been growing interest in exploring the potential role of the vaginal microbiota in the etiology of vulvodynia. This systematic review aims to evaluate the current literature on the association between the vaginal microbiota and vulvodynia. MATERIAL AND METHODS A systematic search of multiple databases, including PubMed, Scopus, Web of Science, Cochrane Library, and Ovid MEDLINE, was conducted to identify relevant peer-reviewed studies up to May 12, 2023. The following search terms were used across these databases: "vulvodynia," "vestibulodynia," "vulvar vestibulitis," "microbiome," "microbiota," and "flora." RESULTS A total of 8 case-control studies were included, the quality of which was assessed using the Newcastle-Ottawa Scale. Data extraction and synthesis were performed using a standardized protocol. In most studies, no major differences were found between the vaginal bacterial composition of women with vulvodynia and that of controls. No specific bacterial taxa were consistently associated with vulvodynia. The relationship between vaginal microbiota diversity and vulvodynia remains to be fully understood. CONCLUSIONS The role of vaginal microbiota in vulvodynia, if any, remains unclear. Because of the cross-sectional nature of the included studies, it is not possible to make any causal inferences. Further research, using larger and more diverse study populations and advanced sequencing techniques, is necessary to gain a better understanding of the potential relationship between the vaginal microbiota and vulvodynia.

Abstract
OBJECTIVES Vulvodynia is an emerging health problem, still insufficiently studied, that causes a significant reduction in quality of life in many women and individuals assigned female sex at birth. Little is known about the effects of diet and metabolic disorders on this condition. The objective of this study was to review currently available evidence on the diet and the nutritional and metabolic status of patients affected by vulvodynia. METHODS Published articles were systematically searched in the PubMed, Scopus, and Web of Science databases. RESULTS The few available studies that reported data on patients' body mass index (BMI) described a BMI within the normal range in most patients affected by vulvodynia, showing no difference or a slightly lower BMI with respect to control individuals. Data on the relationship between metabolic diseases and vulvodynia are lacking. Regarding nutrition, the few available data do not support the prescription of a low-oxalate diet in women with vulvodynia. To date, studies on other dietary behaviors are also lacking. CONCLUSIONS This review emphasizes-for the first time, to our knowledge-the lack of data and the importance of conducting prospective studies investigating the nutritional and metabolic aspects related to the onset, maintenance, and therapy of vulvodynia.

Abstract
OBJECTIVE To provide evidence-based recommendations for the management of chronic pelvic pain in females. TARGET POPULATION This guideline is specific to pelvic pain in adolescent and adult females and excluded literature that looked at pelvic pain in males. It also did not address genital pain. BENEFITS, HARMS, AND COSTS The intent is to benefit patients with chronic pelvic pain by providing an evidence-based approach to management. Access to certain interventions such as physiotherapy and psychological treatments, and to interdisciplinary care overall, may be limited by costs and service availability. EVIDENCE Medline and the Cochrane Database from 1990 to 2020 were searched for articles in English on subjects related to chronic pelvic pain, including diagnosis, overlapping pain conditions, central sensitization, management, medications, surgery, physiotherapy, psychological therapies, alternative and complementary therapies, and multidisciplinary and interdisciplinary care. The committee reviewed the literature and available data and used a consensus approach to develop recommendations. Only articles in English and pertaining to female subjects were included. VALIDATION METHODS The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See online Appendix A (Tables A1 for definitions and A2 for interpretations of strong and conditional [weak] recommendations). INTENDED AUDIENCE Family physicians, gynaecologists, urologists, pain specialists, physiotherapists, and mental health professionals. TWEETABLE ABSTRACT Management of chronic pelvic pain should consider multifactorial contributors, including underlying central sensitization/nociplastic pain, and employ an interdisciplinary biopsychosocial approach that includes pain education, physiotherapy, and psychological & medical treatments. SUMMARY STATEMENTS RECOMMENDATIONS.

Abstract
Chronic pelvic pain (CPP) is generally defined as non-cyclic pain perceived in the pelvic area that has persisted from three to six months or longer and is unrelated to pregnancy. The etiology of CPP is complex, multifactorial, with heterogeneous presentation, and includes several diseases such as endometriosis, adenomyosis, and interstitial cystitis/bladder pain syndrome. It may also be associated with sexual dysfunction, musculoskeletal disorders, and comorbid psychiatric symptoms. Vulvar pain disorders (VPDs) are typically categorized separately from chronic pelvic pain; among all VPDs, vulvodynia is a chronic vulvar pain of unknown etiology, lasting at least 3 months and that might be associated with other potentially linked factors. Proteomics represents a useful approach to study the proteome profiles of clinical samples. In this review, we have considered a selection of articles that have analyzed the protein abundance and novel protein species from various biological samples, including eutopic/ectopic endometrium, urine, serum, follicular, peritoneal fluid, and cervical mucus, potentially involved in the pathogenesis and progression of CPP and VPDs. These findings could represent valuable targets for paving the way for the differential diagnosis and therapeutic management of CPP and VDPs, thereby optimizing both the prevention and treatment of these conditions.

A conceptual model for managing sexual pain with somatocognitive therapy in women with provoked vestibulodynia and implications for physiotherapy practice. Physiother Theory Pract 2023; 39:2539-2552.

Abstract
Somatocognitive therapy is a multimodal physiotherapy treatment developed in the early 2000s to alleviate the burden of chronic pelvic pain. In recent years, somatocognitive therapy has been further developed to treat women with provoked vestibulodynia. This prevalent gynecological pain condition is a subgroup of chronic pelvic pain and the most common form of vulvodynia. Provoked vestibulodynia is a neglected multifactorial pain condition of unknown cause, adversely affecting women's sexual life, relation to their partners and their psychological health. Pain is located at the vulvar vestibule and is provoked by touch or pressure such as sexual intercourse. In the management of sexual pain, somatocognitive therapy combines bodily exploration, pain education, cognitive coping strategies and structured homework to improve sexual function and reduce pain. To support these processes, developing a sound therapeutic alliance with the patient is essential. The aim of this article is to provide a conceptual model for managing provoked vestibulodynia with somatocognitive therapy, including a theoretical rational for this treatment. We base our conceptual model on the biopsychosocial model, i.e., considering the complex interplay of biomedical, emotional/cognitive, psychosexual and interpersonal factors in provoked vestibulodynia management. In addition, implications for practice and a detailed description of somatocognitive therapy for provoked vestibulodynia will be provided, to allow replication in clinical practice and in clinical trials.

Abstract
Studies have shown that psychological distress has a role in the symptomology of localized provoked vulvodynia. Therefore, psychosocial support has been presented as a valuable part of the treatment. However, little is known about which psychological variables that coincide with localized provoked vulvodynia. The purpose of this study was to identify qualities of psychological distress in patients with localized provoked vulvodynia. Patients with localized provoked vulvodynia were consecutively recruited to participate in this cross-sectional questionnaire-based study. Participants completed a self-report questionnaire measuring perfectionism, impostor phenomenon, self-compassion, anxiety and perceived stress. A sample of 30 patients were included. Questionnaire results suggestive of perfectionism was seen in 63%, impostor phenomenon in 80%, low self-compassion in 27%, anxiety in 43% and perceived stress in 23% of the participants. The level of self-compassion was higher in patients in a committed relationship. The investigated qualities appear to be more common in patients with localized provoked vulvodynia than in comparable groups. Impostor phenomenon and perfectionism were particularly common, with more than half of the study population scoring above the cutoff for clinical significance. This motivates research to investigate if interventions targeting impostor phenomenon and perfectionism, may aid in the treatment of localized provoked vulvodynia.

Abstract
INTRODUCTION Botulinum toxin (BoNT) administration has been proposed in the gynecologic field for pelvic, vulvar and vaginal disorders. On this regard, we aimed assessing the therapeutic effectiveness and safety of BoNT usage in the treatment of vaginal, vulvar and pelvic pain disorders. METHODS We searched for all the original articles without date restriction until 31.12.2021. We included all the original articles which administered botulinum toxin in the vulva or vagina of women suffering from vaginismus, dyspareunia, and chronic pelvic pain. Only English language studies and those performed in humans were eligible. We excluded all case reports and pilot study from the qualitative analysis, although we accurately evaluated them. 22 original studies were finally included in the systematic review. RESULTS Botulinum toxin injection was found to be effective in improving vulvar and vaginal dyspareunia, vaginismus, and chronic pelvic pain. No irreversible side effects were detected. Major side effects reported were transient urinary or fecal incontinence, constipation and rectal pain. The risk of bias assessment proved original articles to be of medium quality. No metanalysis could have been performed since lack of congruency in the definition of pathology and methods of botulinum toxin administration. CONCLUSION Data extraction pointed out different endpoints and different methods of analysis. Studies focus on different types of participants and use various techniques and timing. According to the best evidence available, different techniques provide evidence about positive outcomes, with the need for a standardized protocol.

Testosterone use and sexual function among transgender men and gender diverse people assigned female at birth. Am J Obstet Gynecol 2023; 229:669.e1-669.e17.

Abstract
BACKGROUND Testosterone use among transgender people likely impacts their experience of sexual function and vulvovaginal pain via several complex pathways. Testosterone use is associated with decreased estrogen in the vagina and atrophic vaginal tissue, which may be associated with decreased vaginal lubrication and/or discomfort during sexual activity. At the same time, increased gender affirmation through testosterone use may be associated with improved sexual function. However, data on pelvic and vulvovaginal pain among transgender men and nonbinary people assigned female at birth are scarce. OBJECTIVE This study aimed to assess the association between testosterone and sexual function with a focus on symptoms that are commonly associated with vaginal atrophy. STUDY DESIGN We conducted a cross-sectional analysis of 1219 participants aged 18 to 72 years using data collected from 2019 to 2021 from an online, prospective, longitudinal cohort study of sexual and/or gender minority people in the United States (The Population Research in Identity and Disparities for Equality Study). Our analysis included adult transgender men and gender diverse participants assigned female at birth who were categorized as never, current, and former testosterone users. Sexual function was measured across 8 Patient-Reported Outcomes Measurement Information System Sexual Function and Satisfaction domains. RESULTS Overall, 516 (42.3%) participants had never used testosterone, and 602 (49.4%) currently used testosterone. The median duration of use was 37.7 months (range, 7 days to >27 years). Most participants (64.6%) reported genital pain or discomfort during sexual activity in the past 30 days, most commonly in the vagina or frontal genital opening (52.2%), followed by around the clitoris (29.1%) and labia (24.5%). Current testosterone use was associated with a greater interest in sexual activity (β=6.32; 95% confidence interval, 4.91-7.74), higher ability to orgasm (β=1.50; 95% confidence interval, 0.19-2.81), and more vaginal pain or discomfort during sexual activity (β=1.80; 95% confidence interval, 0.61-3.00). No associations were observed between current testosterone use and satisfaction with sex life, lubrication, labial pain or discomfort, or orgasm pleasure. CONCLUSION Testosterone use among transgender men and gender diverse people was associated with an increased interest in sexual activity and the ability to orgasm, as well as with vaginal pain or discomfort during sexual activity. Notably, the available evidence demonstrates that >60% of transgender men experience vulvovaginal pain during sexual activity. The causes of pelvic and vulvovaginal pain are poorly understood but are likely multifactorial and include physiological (eg, testosterone-associated vaginal atrophy) and psychological factors (eg, gender affirmation). Given this high burden, there is an urgent need to identify effective and acceptable interventions for this population.

Acta Obstet Gynecol Scand 2023; 102:1378-1389. [PMID: 36879489 PMCID: PMC10540927 DOI: 10.1111/aogs.14537] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2022] [Revised: 01/13/2023] [Accepted: 02/12/2023] [Indexed: 03/08/2023]
Abstract
INTRODUCTION Vulvodynia, a chronic genital pain disorder with a high lifetime prevalence among women, has a significant negative impact on both women and their partners. Although there is a growing body of literature on the experiences of women with vulvodynia, there has been little research on the condition's implications for partners and romantic relationships. The aim of this study is to explore how heterosexual couples experience living with vulvodynia. MATERIAL AND METHODS Eight Norwegian women diagnosed with vulvodynia by gynecologists were recruited with their partners (couples aged 19-32 years). Data was collected via individual semi-structured interviews and analyzed using inductive thematic analysis. RESULTS Three main themes were identified in the analysis: Mysterious disorder, Social exclusion and Sexual expectations. The results show that the couples struggle with understanding the pain, as well as navigating their social and sexual lives. We discuss these findings in light of a new theoretical model: the fear-avoidance-endurance model of vulvodynia. CONCLUSIONS Heterosexual couples living with vulvodynia experience communication difficulties with partners, health professionals, and their social network. This sustains avoidance and endurance behavior, increasing pain and dysfunction over time and giving rise to feelings of powerlessness and loneliness. Social expectations regarding male and female sexuality also promote guilt and shame for both parties in couples affected by vulvodynia. Our results suggest that heterosexual couples living with vulvodynia, as well as health professionals treating them, should be helped to communicate more effectively in order to break vicious circles of maladaptive avoidance and endurance behavior.

Abstract
Background Chronic pain can occur in the vulva, one of the primary pleasure centers of the body; however, the associations between pleasurable vulvar experiences and chronic vulvar pain have not yet been explored. Aim The aim of this study was to investigate associations between vulvar pleasure and pain experiences in patients with chronic vulvar pain. Methods This was a prospective cross-sectional study of 547 patients (aged ≥17 years) presenting over 10 months to 2 urban outpatient gynecology clinics specializing in vulvar pain. Prior to the initial evaluation, patients completed online validated questionnaires of pain-related anxiety, pain catastrophizing, and sexual functioning, as well as a researcher-developed questionnaire evaluating vulvar pleasure. Patients were divided into groups based on their pleasure and pain experiences. Between-group analyses consisting of t-tests, analyses of variance, and multivariate analyses of variance were conducted. Outcomes Outcomes consisted of total and subscale scores on the Pain Anxiety Symptoms Scale-20, Pain Catastrophizing Scale, Female Sexual Function Index, and a researcher-developed vulvar pleasure questionnaire. Results More than 70% of patients with chronic vulvar pain had experienced vulvar pleasure since the onset of their vulvar pain, with the clitoris as the most common source of pleasure. Average vulvar pleasure intensity was rated 7 (0, no pleasure; 10, extremely pleasurable). Masturbation ranked higher in pleasurable activities than vulvar stimulation by a partner or penetrative intercourse and was the most likely activity to lead to orgasm. When compared with patients who had not experienced vulvar pleasure since the onset of their vulvar pain, patients experiencing both pain and pleasure scored lower on the Pain Anxiety Symptoms Scale-20 total (P = .026) and fear subscale (P = .016), lower on the Pain Catastrophizing Scale total (P = .002) and all subscales (P = .008-.018), and higher on the Female Sexual Function Index total and all subscales (all P ≤ .001). Clinical Implications Incorporating strategies for cultivating vulvar pleasure in patients with chronic vulvar pain may be useful in comprehensive management approaches. Strengths and Limitations Strengths of this study include the novel examination of vulvar pleasure in a population with chronic vulvar pain and a large sample size. Limitations include the lack of a nonclinical comparator group and reliance on patient self-report. Conclusion Results suggest that greater vulvar pleasure is associated with lower pain-related anxiety, lower pain catastrophizing, and higher sexual functioning in patients with chronic vulvar pain conditions.

Abstract
OBJECTIVE The aim of the study is to describe the location, severity, and frequency of genitourinary symptoms in postmenopausal women enrolled in a randomized trial of treatment for vulvovaginal discomfort. METHODS This is a post hoc analysis of enrollment responses for participants in the MsFLASH Vaginal Health Trial. Participants were asked about the severity (0-3), frequency (in days per week) and location (vulvar or vaginal) of itch, dryness, pain/soreness, irritation, as well as severity and frequency of pain with penetration, vaginal discharge, urinary incontinence, and urinary urgency. RESULTS A total of 302 participants were enrolled, with a mean age of 60.9 ± 4.1 years. The mean number of moderate-severe vulvovaginal symptoms experienced by trial participants in the month before enrollment was 3.4 ± 1.5, with a range from 1 to 7. The most commonly reported symptom across all severity categories was vaginal dryness (285/302, 94%), but the one most frequently rated as severe was pain with vaginal penetration (121/302, 40%). Vaginal dryness was the symptom with highest frequency; 53% of participants with that symptom reported experiencing it ≥4 d/wk. For vaginal symptoms, 80% of participants (241/302) reported that at least one of these symptoms occurred during or after sex while only 43% (158/302) reported that at least one vulvar symptom occurred during or after sex. Urinary incontinence (202/302, 67%) and urinary frequency (128/302, 43%) were the two most commonly reported urinary issues. CONCLUSIONS Our data highlight the complexity of genitourinary syndrome of menopause symptoms in quantity, severity, and frequency, suggesting that measuring distress, bother, or interference may be the most comprehensive measure.

Abstract
Introduction Localized provoked vulvodynia (LPV) is a chronic pain condition without an identifiable cause that is localized to a portion of the vulva and provoked by pressure or touch. LPV is a commonly occurring but poorly understood condition lacking consensus on management. Method This scoping review used Arksey and O'Malley's approach to identify and evaluate literature published between 2010 and 2023 that addressed the question: What is the current evidence on the efficacy or effectiveness of pharmacological treatments in the management of LPV? Results This review evaluated 18 papers reporting on the efficacy or effectiveness of oral, topical, and injectable medications. Seven of the studies were randomized controlled trials. Oral gabapentin and oral desipramine showed some improvement in sexual function compared to placebo. Small sample sizes and methodological issues limited confidence in interpreting findings. Pain was reduced in descriptive studies of tricyclic antidepressants, milnacipran, injectable anesthetics, and botulinum toxin. Where pain did not improve with treatment, some oral medications improved participants' mood and sexual function. Some topical agents may be effective in reducing peripherally mediated neuropathic pain. Botulinum toxin was the most well-studied injectable but yielded mixed outcomes related to pain, quality of life, and sexual function. Conclusion There is a lack of convincing evidence to draw conclusions about the efficacy or effectiveness of pharmacological therapies for LPV. The breadth of therapies for treating LPV warrants the development of evidence-based, consensus guidelines for measuring treatment outcomes and improving comparisons across studies. Recommendations for research include addressing methodological shortcomings and diversifying the participant pool to increase the generalizability of findings.

Abstract
Although fear learning mechanisms are implicated in the development, maintenance, exacerbation, and reduction of genital pain, systematic research on how fear of genital pain emerges, spreads, persists, and reemerges after treatment is lacking. This paper provides an overview of the literature on pain-related fear, integrates the ideas on learning and sexual arousal responding, and specifies the pathways through which compromised learning may contribute to the development and persistence of genital pain. In order to refine theories of genital pain and optimize treatments, we need to adopt a biopsychosocial framework to pain-related fear learning and uncover potential moderators that shape individual trajectories. This involves examining the role of physiological processes, subjective experiences, as well as partner and relational cues in fear acquisition, excessive generalization and impaired safety learning, extinction of fear, counterconditioning, and return of fear. Recent methodological advances in fear conditioning and sex research are promising to enable more symptom-specific and ecologically valid experimental paradigms.

Abstract
Vulvodynia is a debilitating condition characterized by painful sensitivity to touch and pressure in the vestibular tissue surrounding the vaginal opening. It is often a "diagnosis of exclusion" of idiopathic pain made in the absence of visible inflammation or injury. However, the association between increased vulvodynia risk and a history of yeast infections and skin allergies has led researchers to explore whether immune mechanisms of dysregulated inflammation might underlie the pathophysiology of this chronic pain condition. Here we synthesize epidemiological investigations, clinical biopsies and primary cell culture studies, and mechanistic insights from several pre-clinical models of vulvar pain. Taken together, these findings suggest that altered inflammatory responses of tissue fibroblasts, and other immune changes in the genital tissues, potentially driven by the accumulation of mast cells may be key to the development of chronic vulvar pain. The association of increased numbers and function of mast cells with a wide variety of chronic pain conditions lends credence to their involvement in vulvodynia pathology and underscores their potential as an immune biomarker for chronic pain. Alongside mast cells, neutrophils, macrophages, and numerous inflammatory cytokines and mediators are associated with chronic pain suggesting immune-targeted approaches including the therapeutic administration of endogenous anti-inflammatory compounds could provide much needed new ways to treat, manage, and control the growing global pandemic of chronic pain.

Abstract
Background: Vulvodynia is defined as a chronic idiopathic vulvar pain condition. This study aimed to investigate the effect of central sensitization on the prognosis of neuromodulator treatment for vulvodynia. Method: A total of 105 patients with vulvodynia who underwent pelvic mapping pain exploration were included and scored according to the Convergence PP Criteria for pelvic pain and central sensitization. The patients were treated according to chronic pelvic pain guidelines, and their response to treatment was evaluated. Results: A total of 35 out 105 patients (33%) with vulvodynia had central sensitization, which was associated with comorbidities, dyspareunia, pain with micturition, and pain with defecation. Dyspareunia and pain with defecation were independent prognostic factors for central sensitization. Patients with central sensitization experienced more pain during intercourse, urination, or defecation, had more comorbidities, and responded worse to treatment. They required more treatment, with a longer response time (over 2 months). Patients with localized vulvodynia were treated with physiotherapy and lidocaine, while patients with generalized vulvodynia were treated with neuromodulators. Amitriptyline was effective in treating patients with generalized spontaneous vulvodynia and dyspareunia. Conclusions: Overall, this study highlights the importance of considering central sensitization in the diagnosis and treatment of vulvodynia and the need for individualized treatment based on the patient's symptoms and underlying mechanisms. Vulvodynia patients with central sensitization had more pain during intercourse, urination, or defecation, and responded worse to treatment, requiring more time and medication.

Distinct neural signaling characteristics between fibromyalgia and provoked vestibulodynia revealed by means of functional magnetic resonance imaging in the brainstem and spinal cord. FRONTIERS IN PAIN RESEARCH 2023; 4:1171160.

Abstract
Introduction Fibromyalgia and provoked vestibulodynia are two chronic pain conditions that disproportionately affect women. The mechanisms underlying the pain in these conditions are still poorly understood, but there is speculation that both may be linked to altered central sensitization and autonomic regulation. Neuroimaging studies of these conditions focusing on the brainstem and spinal cord to explore changes in pain regulation and autonomic regulation are emerging, but none to date have directly compared pain and autonomic regulation in these conditions. This study compares groups of women with fibromyalgia and provoked vestibulodynia to healthy controls using a threat/safety paradigm with a predictable noxious heat stimulus. Methods Functional magnetic resonance imaging data were acquired at 3 tesla in the cervical spinal cord and brainstem with previously established methods. Imaging data were analyzed with structural equation modeling and ANCOVA methods during: a period of noxious stimulation, and a period before the stimulation when participants were expecting the upcoming pain. Results The results demonstrate several similarities and differences between brainstem/spinal cord connectivity related to autonomic and pain regulatory networks across the three groups in both time periods. Discussion Based on the regions and connections involved in the differences, the altered pain processing in fibromyalgia appears to be related to changes in how autonomic and pain regulation networks are integrated, whereas altered pain processing in provoked vestibulodynia is linked in part to changes in arousal or salience networks as well as changes in affective components of pain regulation.

Abstract
The aim of this study was to investigate the severity of chronic vulvar pain in women with vulvodynia and its impact on their health-related quality of life (QL). The study group consisted of 76 women aged 19 to 58. The study was carried out using the diagnostic survey method, i.e., (1) the questionnaire technique, comprising (A) the author's questionnaire (76 questions) and (B) the WHOQOL-BREF questionnaire, and (2) the VAS. When analyzing the severity of vulvar pain on the VAS, the highest proportion of women rated it at level 6 (23.68%). This was significantly determined by certain personal characteristics (age < 25 years old) and sociodemographic characteristics (marital status: unmarried women, divorcees, widows; high school education), each at p < 0.05. Vulvodynia causes a significant deterioration (64.47%) in QL, which is mainly caused by a reduction in the ability to perform activities of daily living (27.63%) and a decrease in sexual satisfaction (27.63%). The level of stress significantly exacerbates pain (p < 0.05). The severity correlates significantly (p < 0.05) and negatively (r < 0) with QL perception, which was rated worst in the physical domain. The use of treatment resulted in a significant improvement in the physical and psychological domains (p < 0.05), and the latter was particularly influenced by physiotherapy (p < 0.05).

Abstract
OBJECTIVE Provoked vestibulodynia (PVD) is a challenging and distressing problem for women. The aim of this study was to examine the effect of hyaluronic acid (HA) in the management of this condition. METHOD This is a retrospective review of 12 women diagnosed with PVD and treated with HA (19 mg/mL) applied, point-by-point, to the vestibular region at 2 mm intervals and at a depth of 0.5 mm. Women completed a pain VAS and a Female Sexual Function Index (FSFI) before and 45 days after treatment. RESULTS An improvement was observed both in mean FSFI scores (17.8 to 23.3; p = 0.003) and mean VAS scores (7.2 to 4.1; p = 0.002) after HA application respectively. However, on a telephone interview 3 months post treatment, five women (41.7 %) complained of recurrence of their dyspareunia. CONCLUSION HA is a promising management option in provoked vestibulodynia. However, further larger studies with possible alternative regimens and longer follow-up are required.

Abstract
Vulvodynia affects 7% of American women, yet clinicians often lack awareness of its presentation. It is underdiagnosed and often misdiagnosed as vaginitis. The etiology of vulvodynia remains unknown, making it difficult to identify or develop effective treatment methods. The purpose of this article is to (1) review the presentation and evaluation of vulvodynia, (2) review the research on vulvodynia treatments, and (3) aid the clinician in the selection of vulvodynia treatment methods. The level of evidence to support vulvodynia treatment varies from case series to randomized controlled trials (RCTs). Oral desipramine with 5% lidocaine cream, intravaginal diazepam tablets with intravaginal transcutaneous electric nerve stimulation (TENS), botulinum toxin type A 50 units, enoxaparin sodium subcutaneous injections, intravaginal TENS (as a single therapy), multimodal physical therapy, overnight 5% lidocaine ointment, and acupuncture had the highest level of evidence with at least one RCT or comparative effectiveness trial. Pre to posttest reduction in vulvar pain and/or dyspareunia in non-RCT studies included studies of gabapentin cream, amitriptyline cream, amitriptyline with baclofen cream, up to 6 weeks' oral itraconazole therapy, multimodal physical therapy, vaginal dilators, electromyography biofeedback, hypnotherapy, cognitive behavioral therapy, cold knife vestibulectomy, and laser therapy. There is a lack of rigorous RCTs with large sample sizes for the treatment of vulvodynia, rendering it difficult to determine efficacy of most treatment methods. Clinicians will be guided in the selection of best treatments for vulvodynia that have the highest level of evidence and are least invasive.

Abstract
(1) Background: The objective was to compare the exploration of chronic pelvic pain syndrome (CPPS) patients in different locations and establish the role of physical examination in CPPS patients. (2) Methods: We reviewed clinical data from 107 female patients with CPPS unresponsive to conventional therapies at Puerta de Hierro University Hospital Madrid, Spain, from May 2018 to June 2022. Patients were classified into three groups: (a) pelvic pain; (b) anorectal pain; or (c) vulvar/perineal pain. (3) Results: Although the demographics of patients with CPPS were different, their physical examinations were strikingly similar. Our study observed a comorbidity rate of 36% and 79% of central sensitization of pain. Seventy-one percent of patients had vulvar allodynia/hyperalgesia. Pain on examination was identified in any pelvic floor muscle, in any pelvic girdle structure, and neuropathic pain in 98%, 96%, and 89%, respectively. Patients with vulvar and perineal pain were more different from the other groups; these patients were younger and had fewer comorbidities and less central sensitization, less anorectal pain, more pain during intercourse, and greater nulliparity (p = 0.022; p = 0.040; p = 0.048; p = 0.000; p = 0.006; p = 0.005). (4) Conclusions: The findings of this study are related to the understanding of the pathophysiology of CPPS. The physical examination confirms the central sensitization of female patients with CPPS, helps us to determine the therapeutic management of the patient, and can be considered as a prognostic factor of the disease.

Abstract
Background: Vulvodynia is defined in this international consensus as persistent vulvar pain that occurs for >3 months without an identifiable cause and with several potential associated factors. At present there is no univocal consensus in the therapeutic treatment of vulvodynia. The methods of intervention are based on various aspects including, above all, the management of painful symptoms. Methods: a research on scientific database such as “Pubmed”, “Medline Plus”, “Medscape” was conducted, using the words “women’s genital pain” and “vulvodynia” for the review of the scientific evidence on the assessment and treatment of women’s genital pain. Results: Among the drugs with pain-relieving action, the most effective in the treatment of vulvodynia would seem to be those with antidepressant and anticonvulsant action, even if their mechanisms of action are not known and there are still insufficient studies able to demonstrate their real validity. Among the least effective are non-steroidal anti-inflammatory drugs (NSAIDs) and corticosteroids. However, the ideal would seem to use a combined treatment with multiple types of drugs. Conclusions: Future studies are needed to draw up a unique therapeutic action plan that considers the stratification of patients with vulvodynia and the variability of the symptom.

Rationale and design of a multicenter randomized clinical trial of vestibulodynia: understanding pathophysiology and determining appropriate treatments (vestibulodynia: UPDATe). Ann Med 2022; 54:2885-2897.

Abstract
BACKGROUND Limited data are available to establish evidence-based management protocols for vestibulodynia (VBD), a chronic vulvar pain condition that affects approximately 14 million women in the U.S. For the purposes of the study, our group subdivided VBD subtypes that may benefit from different types of treatment: 1) VBD peripheral (VBD-p), characterized by pain localized to the vulvar vestibule and 2) VBD central (VBD-c), characterized by VBD alongside one or more other chronic overlapping pain conditions (e.g. irritable bowel syndrome, temporomandibular disorder, and fibromyalgia syndrome) that affect remote body regions. Here, we describe the rationale and design of an NIH-funded multicenter clinical trial comparing the effectiveness of topical and/or systemic medication for alleviating pain and normalizing pain- relevant biomarkers among women with VBD-p and VBD-c. METHODS Participants will be randomly assigned to one of four parallel arms: peripheral treatment with 5% lidocaine + 0.5 mg/ml 0.02% oestradiol compound cream + oral placebo pill, 2) central treatment with the tricyclic antidepressant nortriptyline + placebo cream, 3) combined peripheral cream and central pill treatments, or 4) placebo cream and placebo pill. The treatment phase will last 16 weeks, with outcome measures and biomarkers assessed at 4 time points (0, 8, 16, and 24 weeks). First, we will compare the efficacy of treatments in alleviating pain using standardized tampon insertion with a numeric rating scale and self-reported pain on the short form McGill Pain Questionnaire. Next, we will compare the efficacy of treatments in improving perceived physical, mental, and sexual health using standardized questionnaires. Finally, we will measure cytokines and microRNAs in local vaginal and circulating blood samples using multiplex assays and RNA sequencing, and determine the ability of these biomarkers to predict treatment response. CONCLUSION This is the first multicenter randomized controlled trial to evaluate the efficacy of peripherally and centrally acting medications currently used in clinical practice for treating unique VBD subtypes based on distinct clinical and biological signatures. ADMINISTRATIVE INFORMATION Vestibulodynia UPDATe is a multi-centre, two-by-two factorial designed randomized, double-blind, placebo-controlled trial registered at clinical trials.gov (NCT03844412). This work is supported by the R01 HD096331 awarded to Drs. Nackley, Rapkin, Geller and Carey by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD).Key messagesPeripheral lidocaine and oestradiol and centrally-targeted nortriptyline medications are used for the treatment of pain in women with VBD, but there is a lack of data from well-powered RCTs.This two-by-two factorial RCT will test the efficacy of these medications in VBD subtypes characterized by distinct clinical characteristics and biomarker profiles.We hope that results will provide clinicians with scientific evidence of therapeutic efficacy in distinct VBD subtypes in an effort to direct and optimize treatment approaches.

Abstract
BACKGROUND Provoked vestibulodynia (PVD) is a common pain disorder afflicting primarily young women, and botulinum toxin A (BTA) has been to a limited extent tested as a treatment. AIM Evaluate outcome 12 months after injection with BTA as a treatment for PVD. METHODS We conducted a double-blinded, placebo-controlled trial of twice repeated injections of 50 units of BTA or placebo in the bulbocavernosus muscles, 3 months apart, in women with PVD. Treatment outcome after six months', failed to show any significant difference in pain reduction between the groups, as previously reported. Here, we report treatment outcomes 12 months after the first injections. In addition to injections, participants where instructed to perform pelvic floor exercises during month 6-12. 38 participants/group was calculated to achieve a statistical power of 80% based on an effect size of 20 VAS units (mean score range 56-76±31 SD). OUTCOMES Primary outcome was self-reported dyspareunia or pain at tampon use, using a visual analogue scale (VAS) 0-100. Secondary outcomes were vaginal pressure measurements, psychological health, sexual function and distress. RESULTS From the initial 88 randomized women with PVD, 75 remained at 12 months; 38 in the BTA and 37 in the placebo group. There was no significant difference in primary outcome between the groups. Vaginal pressure in the BTA group had been restored to pre-treatment levels, with no differences between the groups at 12 months. There was an increase in sexual function in the BTA group, with a Female Sexual Function Index of 22.8 (±4.8) compared to the placebo group to 19.7 (±5.0), P=.048. No differences were observed in sexual distress, stress and anxiety. There was an increase in number of women attempting intercourse in the BTA group (74%) compared with placebo (43%), P=.005. Too few patients performed the pelvic floor exercises for this intervention to be analyzed. CLINICAL IMPLICATIONS This study highlights BTA as a safe treatment option for patients with PVD. STRENGTHS AND LIMITATIONS The randomized, double-blinded design and repeated treatments are the major strengths of this study and it is the first study to objectively evaluate muscular effect after BTA injections. The major shortcoming is that few participants performed the pelvic floor exercises, preventing analyses. CONCLUSION At 12 months' follow up, no significant difference in reduction of dyspareunia or pain at tampon use was observed. Women receiving BTA attempted intercourse more often and improved their sexual function compared with women receiving placebo.

Abstract
OBJECTIVE The etiology of localized provoked vulvodynia (LPV) remains unknown, but observations suggest the involvement of the vaginal microbiota. We examined the vaginal microbiota of women with LPV and healthy controls, upon after a low-oxalate diet (LOD). MATERIALS AND METHODS A total of 9 women diagnosed with secondary LPV and 21 healthy controls were recruited from the Galilee Medical Center in Israel and subjected to prospective evaluations of their vaginal microbiota. Total DNA was extracted from vaginal discharge samples provided before and after following LOD for 3 weeks and was then subjected to 16S sequencing. Data obtained were then used to evaluate α and β diversity, identify differentially abundant bacterial taxa in LPV, and determine their impact on the metabolism. RESULTS These evaluations revealed decreased diversity in the vaginal microbiota of women with LPV and identified the Ochrobactrum genus and Pseudomonadaceae family as indicators for LPV. In addition, we identified 23 differentially expressed bacterial metabolic pathways between the LPV and control samples and revealed that LOD could induce changes in the β diversity of LPV vaginal microbiomes, which was further supported by some degree of pain reduction in patients. CONCLUSIONS Localized provoked vulvodynia and LOD were associated with shifts in the vaginal microbiota. However, the impact of these changes on the development of LPV requires additional studies with a larger cohort.

Abstract
Female sexual dysfunctions represent a real widespread problem, usually faced from a psychological point of view; however, millions of women worldwide are impacted by pelvic floor dysfunction, personal shame and social taboos, however, continue to inhibit free conversation on the subject. Women’s quality of life is considerably improved by screening, diagnosing, and controlling urogenital and sexual issues. This review aims to provide a critical perspective of urogenital conditions and common disturbances in female sexual function associated with these issues. It also includes a discussion of postpartum pelvic dysfunction.

Abstract
Background Provoked vulvodynia (PV) is the main cause of vulvar pain and dyspareunia. The etiology of PV has not yet been elucidated. However, PV is associated with a history of recurrent inflammation, and its often accompanied by increases in the numbers of mast cells (MCs) and sensory hyperinnervation in the vulva. Therefore, this study aimed to examine the role of MCs and the early inflammatory events in the development of chronic vulvar pain in a rat model of PV. Methods Mechanical and thermal vulvar sensitivity was measured for 5 months following zymosan vulvar challenges. Vulvar changes in glutamate and nerve growth factor (NGF) were analyzed using ELISA. Immunofluorescence (IF) staining of the vulvar section after 20, 81, and 160 days of the zymosan challenge were performed to test MCs accumulation, hyperinnervation, and expression of pain channels (transient receptor potential vanilloid/ankyrin-1-TRPV1 & TRPA1) in vulvar neurons. Changes in the development of vulvar pain were evaluated following the administration of the MCs stabilizer ketotifen fumarate (KF) during zymosan vulvar challenges. Results Zymosan-challenged rats developed significant mechanical and thermal vulvar sensitivity that persisted for over 160 days after the zymosan challenge. During inflammation, increased local concentrations of NGF and glutamate and a robust increase in MCs degranulation were observed in zymosan-challenged rats. In addition, zymosan-challenged rats displayed sensory hyperinnervation and an increase in the expression of TRPV1 and TRPA1. Treatment with KF attenuated the upregulated level of NGF during inflammation, modulated the neuronal modifications, reduced MCs accumulation, and enhanced mechanical hypersensitivity after repeated inflammation challenges. Conclusion The present findings suggest that vulvar hypersensitivity is mediated by MCs accumulation, nerve growth, and neuromodulation of TRPV1 and TRPA1. Hence, KF treatment during the critical period of inflammation contributes to preventing chronic vulvar pain development.

Abstract
Female sexual dysfunction (FSD) is a much-neglected aspect of feminine health, especially in patriarchal cultures. We collated data from pertinent published literature on FSD to explore the types, associations, and best possible approach to FSD in the Indian context. We fed search words "female sexual dysfunction," "sexual health," "India," into medical search engines such as PubMed, Google Scholar, Clinical Key, ProQuest, SciVal for locating pertinent articles from which data was synthesized and extracted. Female sexual response is complex and is influenced by physiological, behavioral, social, and cultural factors. The latest Diagnostic and Statistical Manual of Mental Disorders-5 criteria classified FSD into female sexual interest/arousal disorder, female orgasmic disorder and genito-pelvic pain/penetration disorder, along with categories common to both genders like substance/drug induced and other unspecified subsets. Diagnosis requires detailed and specific history taking and clinical evaluation to rule out comorbidities. Treatment is multifaceted and prolonged, involving pharmacological, psychological, and behavioral therapy in both partners. Almost all Indian studies in this field have small sample sizes and none of the studies focused on FSD as the primary complaint. FSD is still an unexplored field of Indian medicine. Although newer treatment options and techniques are being explored, there is much to achieve. We need to develop culturally suitable questionnaires taking into account the Indian female psyche. Management should be holistic and involve focused liaison clinics, including dermatology, gynecology, psychiatry, clinical psychology, and urology specialties.

Abstract
Aims: Better documentation of vulvar pain is needed. We examined pain locations marked on general body and genital specific outlines among women with vulvodynia. Methods: 62 women (mean age 32.1 ± 9.5 years) with vulvodynia marked their pain on a digital genital specific outline (22 segments) and 59 of those women also marked their pain on a digital general body outline (48 segments). We used ImageJ software to determine body surface area (BSA) for each outline. Results: On the general body outline, 24/48 segments were marked; 22/22 segments were marked on the genital specific outline. There was a moderate correlation (r = 0.43; p = 0.001) between the BSA marked on the general body outline and the BSA marked on the genital area outline. Conclusions: Findings support concurrent validity of the BSA as a measure of pain location using either outline.
