Relationship Between Childhood Sexual Abuse, Obesity, and Vulvodynia in Adulthood.

OBJECTIVE: The aim of the study is to assess the relationship between childhood sexual abuse, obesity, and vulvodynia among adult women participating in a population-based longitudinal vulvodynia study. MATERIALS AND METHODS: Surveys assessed health status, diagnoses, risk factors, and screening test outcomes for women with vulvodynia. Associations between childhood sexual abuse (CSA) and obesity, CSA and vulvodynia, and obesity and vulvodynia were investigated. A multivariate model was used to determine if obesity mediates and/or modifies the relationship between CSA and vulvodynia. RESULTS: Of 2,277 women participating in the study, 1,647 completed survey data on CSA at 18 months, body mass index at 24 months, and vulvodynia over the first 54 months of the survey. Mean age was 50.9 ± 15.8 years. Overall, race and ethnicity were 77.4% White, 15.7% Black, 2.4% Hispanic, and 4.5% other. Five hundred thirty-nine participants (32.7%) were obese (body mass index >30) and 468 (28.4%) were overweight. Physical CSA before age of 18 years was reported by 20.0% ( n = 329). During the study, 22.0% ( n = 362) screened positive for vulvodynia on one or more surveys. After controlling for demographic variables, both obesity and screening positive for vulvodynia were associated with a history of CSA before age of 18 years ( p = .013 and p < .001, respectively), but obesity was not associated with screening positive for vulvodynia ( p = .865). In addition, multivariate analysis indicated no mediation of the CSA/vulvodynia relationship by obesity. CONCLUSIONS: Although obesity and vulvodynia were independently associated with a history of CSA, obesity did not mediate or modify the relationship between CSA and vulvodynia in adulthood.

Nerve Growth Factor and Selected Cytokines in Women With and Without Vulvodynia.

OBJECTIVE: The aim of the study was to assess the association between cytokines/neurokines after in vitro stimulation with Candida antigen or lipopolysaccharide (LPS) in blood samples among women with and without vulvodynia. MATERIALS AND METHODS: Women with vulvodynia and asymptomatic controls at three offices at the University of Michigan were examined clinically and completed a comprehensive survey in this cross-sectional study. Cytokine/neurokine levels were determined on blood samples using established ELISA protocols. Analysis of 48 cases and 42 ethnically matched controls included descriptive statistics (median, minimal, and maximal levels of cytokines/neurokines), overall and in cases and controls. Because of left-censored measurements, interval censored survival analysis was used to assess the association between case/control status and pain characteristics with cytokine/neurokine levels. RESULTS: Participants ranged in age from 19 to 60 years. Levels of IL1ß, IL1-RA, TNFα, IL-6, and IL-8 increased substantially after LPS stimulation, whereas no response was seen on IFNγ or nerve growth factor (NGF). Each increased after Candida antigen stimulation, although responses to Candida antigen stimulation of IL1ß, IL-6, and TNFα were less robust than after LPS. Only NGF was significantly increased in vulvodynia cases compared with controls (Exp ß (95% CI) = 2.08 [1.08-3.98]) after 24-hour Candida antigen stimulation and persisted when controlled for age, use of oral contraceptives, or history of Candida vulvovaginitis. No association between cytokine/neurokine levels and pain characteristics was found. CONCLUSIONS: Compared with that of control women, whole blood from women with vulvodynia demonstrates an enhanced production of NGF, but not of a set of inflammation-related cytokines, in response to Candida antigen stimulation.

Multimodal Vulvar and Peripheral Sensitivity Among Women With Vulvodynia: A Case-Control Study.

OBJECTIVE: To assess differences in vulvar and peripheral sensitivity between women with and without vulvodynia. METHODS: Women with vulvodynia (n = 41) and age-matched controls (n = 43) seen in the outpatient setting were evaluated via surveys, clinical examination, and multimodal sensory testing (pressure, heat, cold, vibration, and electrical stimulation). The relationships between sensitivity to various sensory modalities and case/control status, as well as by vulvodynia subgroups, were assessed using logistic regression. RESULTS: Women with vulvodynia were more sensitive to pressure and to electrical stimuli than were control women at the vulva (median, 22 vs 230 g and 0.495 vs 0.769 mA, respectively; P < 0.001 for each) and at the thumb (median, 2500 vs 4250 g and 0.578 vs 0.764 mA, respectively; P = 0.006 for pressure, P < 0.001 for electrical stimulation). Heat, cold, and vibration detection thresholds did not differ significantly between these groups (P > 0.025). Those reporting spontaneous pain versus provoked pain had greater pressure sensitivity to the thumb (median, 1850 vs 2690 g; P = 0.020) and greater electrical sensitivity at the introitus (0.450 vs 0.608 mA; P = 0.011), and those with primary versus secondary vulvodynia had substantially greater pressure sensitivity to the thumb (median, 2438 vs 3125 g, P = 0.004). However, having localized versus generalized vulvodynia was not associated with differences in pressure or electrical sensitivity. CONCLUSIONS: Sensitivities to pressure and electrical stimuli are greater among vulvodynia cases than among controls and support 2 previously defined subgroups-those reporting spontaneous pain versus those whose pain only occurred when provoked, and those with primary versus secondary vulvodynia.

Presence of Spontaneous Pain and Comorbid Pain Conditions Identifies Vulvodynia Subgroups.

OBJECTIVE: The aims of the study were to define the heterogeneity of vulvodynia by determining data-driven subgroups within the vulvodynia diagnosis using exploratory cluster analysis and to characterize the subgroups identified. MATERIALS AND METHODS: Included were participants in the longitudinal population-based study of vulvodynia in southeast Michigan who screened positive for vulvodynia at least once during the study. A cluster analysis using variables reflecting vulvar pain characteristics and comorbid pain conditions was conducted. Variables reflecting best separation of clusters were used to assign participants to subgroup categories. Demographic, psychiatric, general health, and other vulvar pain characteristics were summarized for each subgroup, followed by multinomial regression and pairwise comparisons of subgroups on these factors. RESULTS: Of 441 women screening positive for vulvodynia during the course of the study, 393 were eligible on the basis of data requirements. Cluster analysis suggested that best subgroup separation was based on the following 2 variables: (1) presence or absence of spontaneous vulvar pain and (2) presence or absence of other comorbid pain conditions. Subgroups did not differ by age or ethnicity. The subgroup having spontaneous pain and other comorbid conditions demonstrated greatest morbidity in general health measures, psychiatric disorders, and other vulvar pain measures. Primary versus secondary vulvodynia did not vary between subgroups and did not assist in subgroup separation in the cluster analysis. DISCUSSION: Subgroups based on exploratory cluster analysis demonstrated that presence of spontaneous pain and the presence of comorbid pain conditions resulted in best separation of groups. Presence of both spontaneous pain and other comorbid pain conditions identified the group with greatest morbidity.

Vestibular Mast Cell Density in Vulvodynia: A Case-Controlled Study.

OBJECTIVES: To identify whether mast cell densities in vulvar biopsies from the vestibule are associated with vulvodynia. METHODS: We enrolled 100 women aged 19 to 59 years with confirmed vulvodynia cases, 100 racially matched controls, and 100 black control women. All had vulvar biopsies performed at the 7 o'clock position of the vestibule, which were then immunostained to detect c-KIT protein. The numbers of c-KIT positive mast cells per ×400 magnification field were manually counted, and t tests and logistic regression were used to assess the association with case-control status. RESULTS: Of the biopsies, 235 were adequate samples for c-KIT testing for mast cells. The mast cell density was substantially lower in black control women (13.9 ± 10.9) in comparison to white control women (22.5 ± 13.2 p < 0.001): hence the analysis was confined to white cases and racially matched control women. Compared with racially matched controls, cases were younger, more likely to be married, and reported a higher household income. The average number of mast cells per ×400 magnification field overall was 19.1 ± 13.2 (range, 0-62). There was no difference in the mast cell count between racially matched cases (22.4 ± 13.9 per ×400 field) and controls (22.5 ± 13.2) in either the univariate or multivariable analyses. Within the group of cases, there was no difference in mast cell density based on the presence or absence of a variety of urogenital symptoms. CONCLUSIONS: No difference in mast cell density in biopsies of the vestibule was found between white cases and racially matched controls. Black control women have a lower mast cell density compared with white control women.

Race/Ethnicity and Incidence of Pelvic Organ Prolapse in Midlife Women: The Study of Women's Health Across the Nation.

Background: Pelvic organ prolapse (POP) affects a considerable proportion of women. Limited information exists regarding the incidence of POP as women transition through menopause. Using data from the Study of Women's Health Across the Nation (SWAN), this diverse community-based longitudinal cohort study assessed the incidence of symptomatic POP and risk by race/ethnicity. Methods: Self-reported POP was ascertained by questionnaire at 11 approximately annual SWAN visits over a median of 13.3 years of follow-up. We estimated probabilities for reporting POP using interval-censored Kaplan-Meier survival plots. We estimated hazard ratios (HR) and 95% confidence intervals (CI) using interval-censored Cox proportional hazards models. Results: The estimated cumulative probability of POP increased linearly from 2.1% at age 45 to 10.1% by age 65 (4.0% per decade). At age 65, the probability was 4.2%, 4.8%, 8.9%, 9.7%, and 33.9% for Japanese, Chinese, Black, White, and Hispanic women, respectively. Compared with White women, the unadjusted HR for POP was 3.09 (95% CI = 2.18-4.39), 0.96 (0.71-1.31), 0.43 (0.22-0.85), and 0.48 (0.26-0.88) for Hispanic, Black, Chinese, and Japanese women, respectively. After adjustment for financial strain and vaginal birth, the low hazards among Chinese and Japanese women and the high hazard for Hispanic women remained significant. Conclusion: Incidence of symptomatic POP increased as women aged through midlife. Risks varied by race and ethnicity and were not accounted for by population differences in socioeconomic life contexts or the probability of having had a vaginal birth. Although not associated with menopause, health providers should incorporate screening for and information about POP when treating menopausal symptoms and health needs of midlife women. Research on pathophysiological factors associated with increasing POP in midlife is warranted.

Deaf persons' english reading levels and associations with epidemiological, educational, and cultural factors.

One hundred six Michigan d/Deaf persons, part of a study evaluating how to improve d/Deaf persons' understanding of cancer prevention recommendations, had reading levels determined using the Test of Reading Comprehension, Syntactic Sentences. Respondents averaged 52 years old, 59% female, 84% Caucasian, 58% married, and 75% Deaf community members. The mean Test of Reading Comprehension, Syntactic Sentences score was 6.1 (women: 6.2, men: 6.0). Higher scores were associated with greater income (p = .02), employment (p = .01), education (high school p = .002, some college p < .001), English use (child at home, teacher in school, at home now: all p < .001), a hearing spouse (p = .003), hard of hearing/d/Deaf father (p = .02), losing hearing after age 20 years, believing smoking is bad (p < .001), speaking with and satisfaction with physicians and nurses (p < .001), good communication with (p = .01), and comfort discussing cancer with doctors (p < .001). Lower scores were associated with using American Sign Language with physicians and nurses (.019) and Deaf community membership (p = .02). In multivariate analysis, higher scores were associated with higher income, college degree, and teacher using English. Reading levels of a predominantly Deaf population were low. Higher income, college degree, and teacher using English were associated with higher reading levels.

Postoperative sexual concerns and functioning in patients who underwent lysis of vulvovaginal adhesions.

OBJECTIVE: This study aimed to determine satisfaction and functioning before and after surgery among women with lichen planus, who have undergone lysis of vulvovaginal adhesions, and to compare their sexual functioning with those of women without this disorder. MATERIALS AND METHODS: The study was approved by the University of Michigan Internal Review Board. A retrospective self-administered survey was completed by 22 women (50-76 years). Eleven women who had undergone surgery to release vulvovaginal adhesions from lichen planus answered a mailed, 75-item questionnaire about health, sexual functioning (using the Female Sexual Function Index), and satisfaction with surgical outcomes 6 months to 6 years after their lysis of vulvovaginal adhesions followed by long-term vaginal dilation. They were compared with 11 age-matched normal controls. We used descriptive statistics such as mean and SDs to describe the population and χ and t tests to determine significant differences between groups. RESULTS: Surgery in women with lichen planus scarring allowed intercourse in 55% and decreased urination difficulties in 75%. Of the patients, 91% stated they were happy with the surgery and would recommend it to others. However, sexual difficulties may persist even after surgery. Approximately 50% of the patients continue to fear pain. There continues to be differences between cases and controls in sexual discomfort and sexual satisfaction. CONCLUSIONS: After surgery for lichen planus, women tend to be more likely to have intercourse, to have less urinary symptoms or infections, and to have fewer genital symptoms. However, for some, sexual difficulties persisted. It may be wise to consider sexual counseling for this population. Nevertheless, most of the patients stated that they were happy with the surgery and would recommend it to others.

Interpretation of the Sexual Functioning Questionnaire in the presence of vulvar pain.

OBJECTIVE: This study aimed to assess whether the domains identified by items on the Sexual Functioning Questionnaire (SFQ) apply to women with vulvodynia. MATERIALS AND METHODS: Forty-one women with vulvodynia and 43 asymptomatic controls, between the ages 18 and 70 years, were assessed with a physician evaluation and a written survey that included the SFQ. RESULTS: Women with vulvodynia had a higher likelihood of female sexual dysfunction than did controls as indicated by 5 of the seven individual SFQ domains (desire, arousal-lubrication, pain, enjoyment, and partner domains, p < .05). Scored on individual items relating to pain or penetrative sex differed more by vulvodynia presence than did items related to arousal and emotions. Compared with published SFQ psychometrics, factor analysis among women with vulvodynia demonstrated similar factor loadings in 6 of the 7 domains of the SFQ (desire, arousal-sensation, arousal-lubrication, orgasm, partner, and pain), but the enjoyment domain intermingled substantially with these other domains. CONCLUSIONS: The SFQ factor structure is generally valid among women with vulvodynia. However, vulvodynia may impact responses to individual items on questions about pain and/or penetration, which may potentially result in erroneous interpretations.

Impact of a single-session psychosocial counseling intervention for women with vulvodynia.

OBJECTIVE: To evaluate the impact of a single session of psychosocial counseling on patients with vulvodynia. METHODS: Patients diagnosed with vulvodynia at a vulvovaginal specialty clinic were randomly assigned to receive either a one-on-one 30- to 45-min psychosocial counseling session with a psychosexual counselor plus written educational materials (intervention group) or written materials alone (control group). They completed a survey before and 6 weeks after randomization that included demographic information and validated measures of sexual function and illness perception. RESULTS: Thirty-one of 38 (81.6%) women approached chose to participate; 26 of the 31 (83.9%) completed the 6-week follow-up survey. Only the intervention group showed improvement in knowledge about vulvovaginal and sexual health, as well as in most measures of improvement in illness perception, as measured by the Brief Illness Perception Questionnaire (P < 0.05). When compared directly with those in the control group, patients in the intervention group reported increased understanding of their vulvar symptoms (P < 0.005) and lessened emotional impact of these symptoms (P = 0.035). CONCLUSION: Patients receiving one session of the one-on-one psychosocial counseling intervention reported improved understanding and lessened emotional impact of their vulvar symptoms, compared with the control group. This study suggests that improvement may occur following minimal intervention and supports the need for further study.

Relationships between the vaginal microbiota and genitourinary syndrome of menopause symptoms in postmenopausal women: the Study of Women's Health Across the Nation.

OBJECTIVE: To describe vaginal microbiota classified by community state types (CST) in a diverse cohort of postmenopausal women and evaluate relationships among genitourinary syndrome of menopause (GSM) symptoms (vaginal dryness, vulvovaginal irritation, sexual pain, dysuria, urinary urgency), CSTs, estrogen, vaginal maturation index (VMI), and vaginal pH. METHODS: In the Study of Women's Health Across the Nation, 1,320 women aged 60.4 to 72.5 years self-collected (2015-2017) vaginal samples analyzed for microbiota composition and structure (CSTs) using 16S rRNA gene amplicon sequencing, VMI, and pH. GSM symptoms were collected with self-administered questionnaires; interviewers elicited estrogen use and measured body mass index. Serum E2 and E1 were measured using high-performance liquid chromatography. We analyzed data using Pearson χ2 tests, analysis of variance, Kruskal-Wallis tests, and binomial logistic regression. RESULTS: The most frequently occurring CST was low Lactobacillus species IV-C (49.8%); 36.4% of women had CSTs dominated by Lactobacillus species. More than half of the women with vaginal atrophy biomarkers (VMI <50 and pH >5) had CST IV-C0, whereas women using estrogen or with higher E1 and E2 levels had a higher prevalence of Lactobacillus crispatus -dominated CST I ( P values < 0.001). Sexual pain was associated with atrophy biomarkers and independently associated with Streptococcus species-dominated CST IV-C1 (odds ratio, 2.26; 95% confidence intervals, 1.20-4.23). For all other GSM symptoms, we found no consistent associations with E1 or E2 levels, atrophy biomarkers, or any CST. CONCLUSIONS: Although close relationships exist among estrogen, CSTs, VMI, and pH, sexual pain was the only GSM symptom associated with the structure of vaginal microbiota and atrophy biomarkers.

Experience of symptoms, sexual function, and attitudes toward counseling of women newly diagnosed with vulvodynia.

OBJECTIVE: This study aimed to assess health beliefs and behaviors, experience of pain, coping mechanisms, sexual function, and attitudes toward counseling of patients newly diagnosed with vulvodynia. MATERIALS AND METHODS: Participants were enrolled from all newly diagnosed vulvodynia patients seen at the University of Michigan Vulvar Disease Clinic at Chelsea. Participants completed a questionnaire assessing perceptions and beliefs about their vulvodynia, coping ability, sexual function, and interest in counseling. RESULTS: Thirty-one women were enrolled, ranging in age from 21 to 81 years; 68% had current partners. On a scale of 1 to 10 (low to high), participants rated their symptoms as severe-(mean [SD] = 7.42 [1.50]), perceived little control over symptoms (2.61 [2.64]); were very concerned about symptoms (8.77 [1.73]); and were very emotionally affected by their disorder (7.00 [2.82]). During the previous 4 weeks, 52% reported low to no sexual desire; 71% reported being dissatisfied with their overall sex life; 26% were not comfortable saying no to partner sex; 23% to 36% did not attempt penetration; and for 36%, their pain was rated as high or very high. Sixty-one percent of women indicated that they would consider counseling for coping with vulvar pain. In addition, 29% (9/31) said they "would" and 48% (15/31) said they "maybe would" consider seeing a sex therapist for their vulvar pain. CONCLUSIONS: Women with newly diagnosed vulvodynia report substantial impact of vulvar pain but feel little control over symptoms. Sexual desire and sexual satisfaction are low. Most of the respondents would consider counseling to help address these issues.

Effectiveness of videos improving cancer prevention knowledge in people with profound hearing loss.

Deaf persons have a poorer understanding of cancer prevention, which is felt to be partly due to communication barriers. One hundred ninety-seven d/Deaf persons completed a survey and video on cancer prevention. Half viewed a spoken English program designed for hearing persons (control group); the other half viewed an amended program that had American Sign Language, captions, and printed English options added (experimental group). Knowledge was measured before and after the video, including 1 and 6 months later. Respondents were primarily Caucasian, had low incomes, lost hearing at young ages, and had d/Deaf spouses. Although overall knowledge improved after viewing the video, the presence of culture-specific communications (American Sign Language, captions) did not improve scores compared to the control group, either immediately after the intervention or over time. Moreover, percentage correct on all pretest, and almost all post-test, questions was <50% for both experimental and control groups. For all subjects, regardless of which group they were in, a hearing spouse (p < 0.001) and more healthcare information sources (p = 0.001) improved knowledge, while African-Americans showed a trend to lesser improvement (p = 0.06). Using culture-specific language did not improve cancer prevention knowledge in this d/Deaf population, and overall knowledge remained low. More study is needed to determine the best way to increase cancer prevention knowledge in this population.

Patterns of Sexual Activity and the Development of Sexual Pain Across the Menopausal Transition.

OBJECTIVE: To examine whether patterns of sexual intercourse frequency and demographic, menopausal status, genitourinary, health, and psychosocial factors are associated with developing sexual pain across the menopausal transition. METHODS: These were longitudinal analyses of questionnaire data from the multicenter, multiracial and ethnic prospective cohort SWAN (Study of Women's Health Across the Nation) (1995-2008). We used multivariable discrete-time proportional hazards models to examine whether incident sexual pain was associated with preceding long-term (up to 10 visits) or short-term (two and three visits) sexual intercourse frequency patterns or other factors (eg, menopause status, genitourinary symptoms, lifestyle factors, and mental health). RESULTS: Of the 2,247 women with no sexual pain at baseline, 1,087 (48.4%) developed sexual pain at least "sometimes" up to 10 follow-up visits over 13 years. We found no consistent association between prior patterns of sexual intercourse frequency and development of sexual pain. For example, neither decreases in intercourse frequency from baseline (adjusted hazard ratio [aHR] 0.93, 95% CI 0.73-1.19) nor decreases in frequency over three prior visits (aHR 1.00, 95% CI 0.72-1.41) were associated with incident pain. Reasons for interruptions in intercourse activity at the prior visit, including lack of interest (aHR 1.64, 95% CI 0.74-3.65) and relationship issues (aHR 0.36, 95% CI 0.04-2.88), were not associated with developing pain. Being postmenopausal using hormone therapy (aHR 3.16, 95% CI 1.46-6.85), and reported vaginal dryness (aHR 3.73, 95% CI 2.88-4.83) were most strongly associated with incident sexual pain. CONCLUSION: Long-term and short-term declines in sexual intercourse frequency across the menopausal transition were not associated with increased hazard of developing pain with intercourse. This empirical evidence does not support the common belief that a reduction in women's sexual frequency is responsible for their symptoms of sexual pain.

Vulvodynia.

Vulvodynia is a condition that occurs in 8-10% of women of all ages and is characterized by pain at the vulva that is present during sexual and/or non-sexual situations. Diagnosis is established through careful medical history and pelvic examination, including the cotton-swab test. The onset and maintenance of vulvodynia involves a complex interplay of peripheral and central pain mechanisms, pelvic floor muscle and autonomic dysfunction, anxiety, depression and childhood maltreatment as well as cognitive-affective, behavioural and interpersonal factors. Given the absence of empirically supported treatment guidelines, a stepwise approach of pelvic floor physical therapy and cognitive behavioural therapy as well as medical management is suggested, with surgery as the last option. Vulvodynia has a negative effect on the quality of life of women and their partners, and imposes a profound personal and societal economic burden. In addition, women with vulvodynia are more likely to report other chronic pain conditions, which further alters their quality of life. Future efforts should aim to increase girls', women's and healthcare professionals' education and awareness of vulvodynia, phenotype different subgroups of women based on biopsychosocial characteristics among more diverse samples, conduct longitudinal studies and improve clinical trial designs.

Cancer prevention knowledge of people with profound hearing loss.

BACKGROUND: Deaf persons, a documented minority population, have low reading levels and difficulty communicating with physicians. The effect of these on their knowledge of cancer prevention recommendations is unknown. METHODS: A cross-sectional study of 222 d/Deaf persons in Michigan, age 18 and older, chose one of four ways (voice, video of a certified American Sign Language interpreter, captions, or printed English) to complete a self-administered computer video questionnaire about demographics, hearing loss, language history, health-care utilization, and health-care information sources, as well as family and social variables. Twelve questions tested their knowledge of cancer prevention recommendations. The outcome measures were the percentage of correct answers to the questions and the association of multiple variables with these responses. RESULTS: Participants averaged 22.9% correct answers with no gender difference. Univariate analysis revealed that smoking history, types of medical problems, last physician visit, and women having previous cancer preventive tests did not affect scores. Improved scores occurred with computer use (p = 0.05), higher education (p < 0.01) and income (p = 0.01), hearing spouses (p < 0.01), speaking English in multiple situations (p < 0.001), and in men with previous prostate cancer testing (p = 0.04). Obtaining health information from books (p = 0.05), physicians (p = 0.008), nurses (p = 0.03) or the internet (p = 0.02), and believing that smoking is bad (p < 0.001) also improved scores. Multivariate analysis revealed that English use (p = 0.01) and believing that smoking was bad (p = 0.05) were associated with improved scores. CONCLUSION: Persons with profound hearing loss have poor knowledge of recommended cancer prevention interventions. English use in multiple settings was strongly associated with increased knowledge.

Environmental Exposure History and Vulvodynia Risk: A Population-Based Study.

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.

Vulvodynia incidence and remission rates among adult women: a 2-year follow-up study.

OBJECTIVE: To estimate the incidence and remission rates of vulvodynia over a 2-year period. METHODS: A 2-year follow-up survey was sent to the University of Michigan Women's Health Registry members who had participated in a previously reported, validated survey. Changes in clinical status, incidence, and remission rates for vulvodynia were estimated, as were factors associated with new onset or remission of symptoms, using univariable and multivariable analyses. RESULTS: Of 1,037 women enrolled in the initial study, 744 women (71.7%) completed an online or written follow-up survey between September 2006 and March 2007. Of the 372 asymptomatic women controls at initial enrollment, 13 (3.5%, 95% confidence interval 1.6-5.4%) had developed vulvodynia during the 2-year follow-up period; nine (2.2%) of these had ongoing symptoms. Of 45 women with vulvodynia at initial enrollment, 10 (22.2%, 95% confidence interval 10.1-34.4%) indicated their symptoms had resolved. Factors at enrollment that were associated with incidence of vulvodynia were younger age and history of pain after intercourse. Remission was more common in women who did not have pain after intercourse and in those who reported less severe pain at enrollment. CONCLUSION: Based on 2-year follow-up, each year approximately one in 50 women develop symptoms of vulvodynia, and one in 10 women with vulvodynia report remission of symptoms.

A survey on diagnosis and treatment of vulvodynia among vulvodynia researchers and members of the International Society for the Study of Vulvovaginal Disease.

OBJECTIVE: To survey members of the International Society for the Study of Vulvovaginal Disease and authors of recent related medical publications for whom e-mail addresses were available to assess current opinion and practices. STUDY DESIGN: In a cross-sectional online survey of potential participants, characteristics of respondents and their preferred diagnostic criteria and treatment modalities for vulvodynia were assessed using univariate and multivariate methods. RESULTS: Of recipients, 61.0% completed the survey. Of these, 86.7% were active in diagnosing or treating women with vulvodynia and 41.3% were currently active in vulvodynia research. Of respondents, > 80% include a history, a genital visual examination and vulvar pressure sensitivity testing in their evaluation of women with vulvar pain. Laboratory assessments were less likely to be rated essential or helpful. Of participants, > 80% rated as very effective or somewhat effective tricyclic antidepressants, pelvic floor physical therapy and psychologic counseling. Most indicated they have made the diagnosis of vulvodynia in conjunction with other vulvovaginal diagnoses and agreed that vulvodynia does remit for some women. CONCLUSION: Despite many diagnostic and treatment options available, some consensus on diagnostic and treatment preferences for vulvodynia was identified. Further research to develop the evidence base for diagnostic and treatment decisions is needed.
