Abstract
Localized provoked vulvodynia (LPV) affects ∼14 million people in the US (9% of women), destroying lives and relationships. LPV is characterized by chronic pain (>3 months) upon touch to the vulvar vestibule, which surrounds the vaginal opening. Many patients go months or years without a diagnosis. Once diagnosed, the treatments available only manage the symptoms of disease and do not correct the underlying problem. We have focused on elucidating the underlying mechanisms of chronic vulvar pain to speed diagnosis and improve intervention and management. We determined the inflammatory response to microorganisms, even members of the resident microflora, sets off a chain of events that culminates in chronic pain. This agrees with findings from several other groups, which show inflammation is altered in the painful vestibule. The vestibule of patients is acutely sensitive to inflammatory stimuli to the point of being deleterious. Rather than protect against vaginal infection, it causes heightened inflammation that does not resolve, which coincides with alterations in lipid metabolism that favor production of proinflammatory lipids and not pro-resolving lipids. Lipid dysbiosis in turn triggers pain signaling through the transient receptor potential vanilloid subtype 4 receptor (TRPV4). Treatment with specialized pro-resolving mediators (SPMs) that foster resolution reduces inflammation in fibroblasts and mice and vulvar sensitivity in mice. SPMs, specifically maresin 1, act on more than one part of the vulvodynia mechanism by limiting inflammation and acutely inhibiting TRPV4 signaling. Therefore, SPMs or other agents that target inflammation and/or TRPV4 signaling could prove effective as new vulvodynia therapies.

Abstract
Atopic dermatitis (AD) is associated with cutaneous dysbiosis, barrier defects, and immune dysregulation, but the interplay between these factors needs further study. Early-onset barrier dysfunction may facilitate an innate immune response to commensal organisms and, consequently, the development of allergic sensitization. We aimed to compare the cutaneous microbiome in patients with active dermatitis with and without a history of childhood flexural dermatitis (atopic dermatitis). Next-gen Ion-Torrent deep-sequencing identified AD-associated changes in the skin bacterial microbiome ("bacteriome") and fungal microbiome ("mycobiome") of affected skin in swabs from areas of skin affected by dermatitis. Data were analyzed for diversity, abundance, and inter-kingdom correlations. Microbial interactions were assessed in biofilms using metabolic activity (XTT) assay and scanning electron microscopy (SEM), while host-pathogen interactions were determined in cultured primary keratinocytes exposed to biofilms. Increased richness and abundance of Staphylococcus, Lactococcus, and Alternaria were found in atopics. Staphylococcus and Alternaria formed robust mixed-species biofilms (based on XTT and SEM) that were resistant to antifungals/antimicrobials. Furthermore, their biofilm supernatant was capable of influencing keratinocytes biology (pro-inflammatory cytokines and structural proteins), suggesting an additive effect on AD-associated host response. In conclusion, microbial inter-kingdom and host-microbiome interactions may play a critical role in the modulation of atopic dermatitis to a greater extent than in non-atopic adults with allergic contact dermatitis.

Specialized Pro-resolving Mediators Reduce Pro-nociceptive Inflammatory Mediator Production in Models of Localized Provoked Vulvodynia. THE JOURNAL OF PAIN 2021; 22:1195-1209.

Abstract
Localized provoked vulvodynia (LPV) is the most common cause of chronic dyspareunia in premenopausal women, characterized by pain with light touch to the vulvar vestibule surrounding the vaginal opening. The devastating impact of LPV includes sexual dysfunction, infertility, depression, and even suicide. Yet, its etiology is unclear. No effective medical therapy exists; surgical removal of the painful vestibule is the last resort. In LPV, the vestibule expresses a unique inflammatory profile with elevated levels of pro-nociceptive proinflammatory mediators prostaglandin E2 (PGE2) and interleukin-6 (IL-6), which are linked to lower mechanical sensitivity thresholds. Specialized pro-resolving mediators (SPMs), lipids produced endogenously within the body, hold promise as an LPV treatment by resolving inflammation without impairing host defense. Ten of 13 commercially available SPMs reduced IL-6 and PGE2 production by vulvar fibroblasts, administered either before or after inflammatory stimulation. Using a murine vulvar pain model, coupling proinflammatory mediator quantification with mechanical sensitivity threshold determination, topical treatment with the SPM, maresin 1, decreased sensitivity and suppressed PGE2 levels. Docosahexaenoic acid, a precursor of maresin 1, was also effective in reducing PGE2 in vulvar fibroblasts and rapidly restored mouse sensitivity thresholds. Overall, SPMs and their precursors may be a safe and efficacious for LPV. Perspective: Vulvodynia, like many pain conditions, is difficult to treat because disease origins are incompletely understood. Here, we applied our knowledge of more recently discovered vulvodynia disease mechanisms to screen novel therapeutics. We identified several specialized pro-resolving mediators as likely potent and safe for treating LPV with potential for broader application.

Abstract
Localized provoked vulvodynia (LPV) causes dyspareunia among reproductive aged women. We review the pathogenesis of LPV and suggest that LPV is an inflammatory pain syndrome of the vestibular mucosa triggered by microbial antigens in a susceptible host. Tissue inflammation and hyperinnervation are characteristic findings which explain symptoms and clinical signs. Education of health care providers of LPV is important since this condition is common, often unrecognized, and patients often become frustrated users of health care. Research is needed on the antigen triggers of the syndrome. Randomized clinical trials are needed to evaluate treatment modalities.

Abstract
Gynecological and obstetrical infectious diseases are an important component of women's health. A system approach to gynecological and obstetrical infection helps unify and classify microbial etiology and pathogenesis within a clinical anatomical framework of lower and upper genital tract syndromes. The reproductive system of women includes the vulva, vagina, cervix, uterus, fallopian tubes and ovaries. During pregnancy, additional tissues include the chorioamnion and placenta together with the fetus and amniotic fluid. We review in two parts reproductive system infection syndromes in women using selected research results to illustrate the clinical utility of the system approach in terms of diagnosis, treatment and prevention. We conclude that a reproductive system perspective will lead to improvements in understanding, management and prevention of these diseases.

Abstract
The prevention of allergic contact dermatitis hinges on maintaining the integrity of the skin barrier and responding appropriately when it is disturbed. Although intact skin is subject to sensitization via highly irritating allergens, such as poison ivy, acutely inflamed and chronically inflamed skin is subject to sensitization to allergens without inherent irritant potential. In the chronically inflamed state of atopic dermatitis, sensitization to proteins, such as food, also carries a risk for systemic contact dermatitis via ingestion of the allergen. Minimizing the development of irritant dermatitis is key to preventing sensitization. However, in patients with already chronically inflamed skin, reducing the use of products to the involved areas, recommending hypoallergenic products with caution, and taking measures to prevent biofilm formation are also integral to preventing sensitization to chemicals and proteins, such as food and commensal organisms.

Abstract
BACKGROUND Up to 30% of women with vaginal symptoms are not assigned a diagnosis after standard diagnostic assessment. METHODS We compared premenopausal women with idiopathic vaginitis (IV) or vulvodynia (VVD) to healthy controls. Microbiota were characterized using rRNA sequencing. Cytokines/chemokines (IL-10, IL-1α, IL-1β, IL-6, IL-8, IL-2, IL-18, IL-4, IL-9, and IL-13) were measured in vaginal lavage fluid using the Meso Scale Discovery platform or ELISA (IL-1ra). Immunoglobulins were measured in vaginal lavage fluid using a bead-based immunoassay (Millipore). Cases and controls were compared using Kruskal-Wallis, analysis of variance, and linear regression or (for microbiome composition) the Bray-Curtis dissimilarity statistic. RESULTS We compared 20 women with IV, 30 with VVD, and 52 controls. Most (80%) had greater than 90% 16S rRNA gene sequences from Lactobacillus crispatus, L. jensenii, L. gasseri, or L. iners. In analyses adjusted for age and hormonal contraception (HC), Gardnerella vaginalis was less prevalent and abundant in women with VVD (2/30, 7%) versus controls (16/52, 31%) or IV (5/20, 25%) (P = 0.030). Bray-Curtis dissimilarity was not significantly different between IV and controls or VVD. Fungal sequences were only detected in 5 participants: 2 control, 1 IV, 2 VVD. In univariate analysis, cytokines were not associated with diagnosis. Median vaginal concentration of IgE (but not other immunoglobulins) was lower in women with VVD (P = 0.006). CONCLUSIONS Minimal differences in vaginal microbiota and inflammatory markers between women with IV, VVD or controls suggest no striking association between vaginal bacteria, fungi or inflammation and diagnosis in these women.

Abstract
OBJECTIVES Allergic contact dermatitis is an uncommon but important cause of skin disease in the anogenital region. Relevant allergens are described in women and less commonly in men. The aim of this study was to describe outcomes of patch testing in men and women presenting with anogenital dermatoses. MATERIALS AND METHODS Cases patch tested for anogenital conditions at 2 patch test clinics in Sydney, Australia, from 2002 to 2017 were reviewed. Positive and relevant patch test reactions were recorded. RESULTS Thirty-seven women and 27 men were included. Dermatitis was the most common diagnosis, followed by psoriasis and lichen sclerosus. Thirty percent had a final diagnosis of allergic contact dermatitis. The most frequent relevant allergens were fragrance mix I (9%), patients own products (9%), Myroxylon pereirae (8%), cocamidopropyl betaine (3%), and benzocaine (3%). CONCLUSIONS The top positive and relevant allergens seen were in concordance with other reports from Australia and the rest of the world. Fragrances and medicaments are common allergens, and it is recommended that products used on anogenital skin be fragrance free. Testing patients own products is imperative.

Abstract
BACKGROUND Risk factors for vulvodynia continue to be elusive. We evaluated the association between past environmental exposures and the presence of vulvodynia. MATERIALS AND METHODS The history of 28 lifetime environmental exposures was queried in the longitudinal population-based Woman-to-Woman Health Study on the 24-month follow-up survey. Relationships between these and vulvodynia case status were assessed using multinomial logistic regression. RESULTS Overall, 1585 women completed the 24-month survey, the required covariate responses, and questions required for case status assessment. Screening positive as a vulvodynia case was associated with history of exposures to home-sprayed chemicals (insecticides, fungicides, herbicides-odds ratio [OR] 2.47, 95% confidence interval [CI] 1.71-3.58, p < 0.0001), home rodent poison and mothballs (OR 1.62, 95% CI 1.25-2.09, p < 0.001), working with solvents and paints (OR 2.49, 95% CI 1.68-3.70, p < 0.0001), working as a housekeeper/maid (OR 2.07, 95% CI 1.42-3.00, p < 0.0001), working as a manicurist/hairdresser (OR 2.00, 95% CI 1.14-3.53, p < 0.05), and working at a dry cleaning facility (OR 2.13, 95% CI 1.08-4.19, p < 0.05). When classified into nine individual environmental exposure categories and all included in the same model, significant associations remained for four categories (home-sprayed chemicals, home rodent poison or mothballs, paints and solvents, and working as a housekeeper). CONCLUSIONS This preliminary evaluation suggests a positive association between vulvodynia and the reported history of exposures to a number of household and work-related environmental toxins. Further investigation of timing and dose of environmental exposures, relationship to clinical course, and treatment outcomes is warranted.

Abstract
Vulvodynia refers to pain in the vulva of at least 3 months’ duration in the absence of a recognized underlying cause. Provoked, localized vestibulodynia is the term used to describe superficial pain confined to the vulvar vestibule, provoked by touch. This review will focus on provoked vestibulodynia with regard to its suggested causative factors and will discuss the role of inflammation, vulvovaginal infections, mucosal nerve fiber proliferation, hormonal associations, central pain mechanisms, pelvic floor muscle dysfunction, and genetic factors. Clinical observations, epidemiological studies, and data from basic research emphasize the heterogeneity of vulvar pain syndromes. There is a critical need to perform prospective, longitudinal studies that will allow better diagnostic criteria and subgrouping of patients that would lead to improvements in our understanding of provoked vestibulodynia and its treatment.

Abstract
Localised provoked vulvodynia (LPV) is a common, chronic, and disabling condition: patients experience profound pain and a diminished quality of life. The aetiologic origins of vulvodynia are poorly understood, yet recent evidence suggests a link to site-specific inflammatory responses. Fibroblasts isolated from the vestibule of LPV patients are sensitive to proinflammatory stimuli and copiously produce pain-associated proinflammatory mediators (IL-6 and PGE2 ). Although LPV is a multifactorial disorder, understanding vulvar inflammation and targeting the inflammatory response should lead to treatment advances, especially for patients exhibiting signs of inflammation. NFκB (already targeted clinically) or other inflammatory components may be suitable therapeutic targets. TWEETABLE ABSTRACT Vulvodynia is a poorly understood, prevalent, and serious women's health issue requiring better understanding to improve therapy.

Abstract
OBJECTIVE Our goal was to gain a better understanding of the inflammatory pathways affected during localized vulvodynia, a poorly understood, common, and debilitating condition characterized by chronic pain of the vulvar vestibule. STUDY DESIGN In a control matched study, primary human fibroblast strains were generated from biopsies collected from localized provoked vulvodynia (LPV) cases and from age- and race-matched controls. We then examined intracellular mechanisms by which these fibroblasts recognize pathogenic Candida albicans; >70% of vulvodynia patients report the occurrence of prior chronic Candida infections, which is accompanied by localized inflammation and elevated production of proinflammatory/pain-associated interleukin (IL)-6 and prostaglandin E2 (PGE2). We focused on examining the signaling pathways involved in recognition of yeast components that are present and abundant during chronic infection. RESULTS Dectin-1, a surface receptor that binds C albicans cell wall glucan, was significantly elevated in vestibular vs external vulvar cells (from areas without pain) in both cases and controls, while its abundance was highest in LPV cases. Blocking Dectin-1 signaling significantly reduced pain-associated IL-6 and PGE2 production during the response to C albicans. Furthermore, LPV patient vestibular cells produced inflammatory mediators in response to low numbers of C albicans cells, while external vulvar fibroblasts were nonresponsive. Inhibition of nuclear factor kappa-light-chain-enhancer of activated B cells (proinflammatory transcription factor) nearly abrogated IL-6 and PGE2 production induced by C albicans, in keeping with observations that Dectin-1 signals through the nuclear factor kappa-light-chain-enhancer of activated B cells pathway. CONCLUSION These findings implicate that a fibroblast-mediated proinflammatory response to C albicans contributes to the induction of pain in LPV cases. Targeting this response may be an ideal strategy for the development of new vulvodynia therapies.

Abstract
Vulvovaginal candidiasis infections are estimated to occur at least once during the lifetime of 75% of the female population. It has been proposed that some women with recurrent vulvovaginal candidiasis (RVVC) develop sensitization to Candida albicans and clinically improve in response to Candida immunotherapy. Here, we report a case series of 12 women diagnosed with chronic vulvovaginal Candida hypersensitivity subsequently treated with Candida immunotherapy and review potential systemic and localized host immune defense mechanisms involved in C. albicans overgrowth and sensitization. A retrospective review of vulvovaginal Candida hypersensitivity in women who were treated with C. albicans immunotherapy over the past eight years was conducted. Twelve women who qualified for a diagnosis of vulvovaginal Candida hypersensitivity were treated with Candida immunotherapy. Eleven of the 12 (92%) women reported clinical improvement after immunotherapy. The majority of these women were not sensitized to seasonal or perennial aeroallergens and clinically responded to lower concentrations of C. albicans allergen than what has been previously reported. In general, Candida immunotherapy was well tolerated. Chronic vulvovaginal Candida hypersensitivity is an underrecognized disorder by primary care physicians and therefore an undertreated disorder by allergists. A double-blinded, placebo-controlled randomized trial is necessary to firmly establish the efficacy of treatment with Candida immunotherapy. This investigation should be designed to include mechanistic studies that would help to better understand the etiology of this disorder.

Abstract
Vulvodynia is a complex disorder reported by up to 16% of women in the general population. While most patients describe it as burning, stinging, irritation, or rawness, it is underreported and underrecognized by providers. Vulvodynia is costly both economically and psychologically due to its negative impact on quality of life. Vulvodynia is a diagnosis of exclusion with unknown etiology and may involve multiple sources of pain in the same woman. Thus, there are no clinical or histopathologic criteria for the diagnosis other than consideration and careful evaluation to exclude other causes of pain. Successful therapy often requires a multidisciplinary approach with more than one therapeutic intervention to address the physical, psychological, psychosexual, and relationship components.

Abstract
CONTEXT Vulvodynia is a complex and multifactorial clinical condition. It is defined as chronic vulvar discomfort characterized by burning, stinging or irritation. Its diagnostic difficulty and treatment is known. OBJECTIVES To review the medical literature of the last 10 years from a critical point of view. EVIDENCE ACQUISITION A search was made in Medline/Pubmed and the Cochrane Library using the terms vulvodynia and vestibulodynia to which etiology, epidemiology, diagnosis, neurophysiological test and treatment or management, were added. EVIDENCE SYNTHESIS In spite of the advances achieved in all of the aspects of vulvodynia, the methodology used at present in many cases does not have the desirable statistical soundness: there are few control or placebo-controlled groups and double-blind studies. Uniformity is lacking in the scales, indexes and questionnaires for the correct evaluation of pain before and after the treatment and debatable diagnostic criteria are use. The limited use of neurophysiological diagnostic resources that validate the clinical findings has been observed in the studies analyzed. In most of the works, the medical treatments have been shown to be ineffective. Physiotherapy and cognitive-behavioral therapy seem to be promising therapeutic tools. Surgery (vestibulectomy) stands out by its demonstrated efficacy in the publications studied. CONCLUSIONS A multidisciplinary approach is always necessary. Topical medical, psychological and physical therapy treatments may have sum effects and become an alternative to surgery. New pathways of research and more regulated studies are required.

Abstract
Background. Recurrent vulvovaginal candidiasis (RVC) is an increasing challenge in clinical practice. Objective. The purpose of this study was to reduce the episodes of RVC through the intake of fluconazole 200 mg/dose with a personalized regimen at growing administration intervals with a probiotic. Method. 55 patients received a 200 mg fluconazole as an induction dose for 3 alternate days. Symptoms resolution after 10-14 days made the patients eligible to continue with a maintenance therapy of fluconazole weekly for one month, followed by 200 mg after 10, 15, 20 and 30 days. Patients were allowed to move on to the next level of maintenance therapy only if they were symptom free. Patients were also given a probiotic with Beta Glucan and Echinacea Purpurea. Results. Among the 55 patients enrolled, four (7%) have withdrawn after the induction phase. 51 patients completed the whole therapeutic maintenance period, and eight (15,6%) experienced a recurrence before the end of the therapy. Five women (9,8%) relapsed (two after 2 months and three after 6 months). Conclusion. The positive results of our study prove the effectiveness of an individualized protocol for a rather short period, with a slowly decreasing administration of fluconazole + probiotic.

Abstract
The causes of chronic vulvar pain are many and when not accompanied by obvious physical signs they are difficult to unravel. Many common vulvar dermatoses can manifest without obvious erythema or mucocutaneous lesions, as can some less common disorders of both infectious and allergic origin. In addition localized and generalized vulvar dysesthesia, recently defined chronic pain syndromes of neurogenic origin, can also occur in the vulvar area. Chronic vulvovaginal symptoms in early stages are often presumptuously labeled as vulvovaginal candidiasis (VVC) by patients and clinicians alike, which can delay accurate diagnosis. When presented with chronic vulvar pain unaccompanied by verifiable signs, the clinician must effect a sensitive integration of a detailed medical history, including temporal associations of all potential exposures, with more definitive diagnostic tools. Effective use of those available tools can improve initial diagnosis, thus allowing prompt initiation of effective therapy. Optimal therapy will recognize the significant psychological distress that accompanies any chronic pain syndrome.

Abstract
Atopic dermatitis is a common chronic skin condition. A subset of patients with head and neck dermatitis may have a reaction to Malassezia flora fueling their disease. Although there are no documented differences in Malassezia species colonization, patients with head and neck atopic dermatitis are more likely to have positive skin prick test results and Malassezia-specific IgE compared with healthy control subjects and patients with atopy without head and neck dermatitis. There is no clear relationship with atopy patch testing. The reaction to Malassezia is likely related to both humoral- and cell-mediated immunity. Clinically, Malassezia allergy may be suspected in patients with atopic dermatitis and: (1) head and neck lesions; (2) exacerbations during adolescence or young adulthood; (3) severe lesions recalcitrant to conventional therapy; and (4) other atopic diseases. There is literature to suggest that these patients will benefit from a 1- to 2-month course of daily itraconazole or ketoconazole followed by long-term weekly treatment.

Abstract
OBJECTIVE The objective of the study was to determine whether vestibular fibroblasts from vulvar vestibulitis (VVS) patients produce higher proinflammatory cytokine levels when provoked with Candida albicans (yeast) and alpha-melanocyte-stimulating hormone (alpha-MSH) in vitro. STUDY DESIGN Twenty anatomically defined fibroblast strains from patients and age-matched controls were stimulated with 5 regimens: no stimulus, alpha-MSH, heat-killed yeast, alpha-MSH plus yeast, and interleukin (IL)-1beta. Supernatant products included the following: granulocyte macrophage colony-stimulating factor, interferon-gamma, IL-10, IL-12, IL-1beta, IL-2, IL-4, IL-6, IL-8, and tumor necrosis factor-alpha were assayed. RESULTS Coincubation with alpha-MSH plus yeast significantly increased IL-6 (3-fold) and IL-8 (greater than 40-fold) production in patients and controls. Vestibular fibroblast exceeded external vulvar fibroblast production of IL-1beta, IL-6, and IL-8 following yeast alone and alpha-MSH plus yeast stimuli in patients and controls. Substratified by anatomic origin, vestibular fibroblasts from VVS patients produced the highest relative levels of IL-1beta, IL-6, and IL-8 at baseline and following the yeast-alone regimen. CONCLUSION Localized pain of VVS may results from regionally elevated cytokines produced by vulvar vestibule-specific fibroblasts.

Abstract
That sexual symptoms can signal serious underlying disease confirms the importance of sexual enquiry as an integral component of medical assessment. Data on sexual function are sparse in some medical specialties. However, increased scientific understanding of the central and peripheral physiology of sexual response could help to identify the pathophysiology of sexual dysfunction from disease and medical interventions, and also to ameliorate or prevent some dysfunctions. Many common general medical disorders have negative effects on desire, arousal, orgasm, ejaculation, and freedom from pain during sex. Chronic disease also interferes indirectly with sexual function, by altering relationships and self-image and causing fatigue, pain, disfigurement, and dependency. Current approaches to assessment of sexual dysfunction are based on models that combine psychological and biological aspects.
