Pelvic floor muscle functioning in women with vulvar vestibulitis syndrome.

Vaginal sEMG biofeedback and pelvic floor physical therapists' manual techniques are being increasingly included in the treatment of vulvar vestibulitis syndrome (VVS). Successful treatment outcomes have generated hypotheses concerning the role of pelvic floor pathology in the etiology of VVS. However, no data on pelvic floor functioning in women with VVS compared to controls are available. Twenty-nine women with VVS were matched to 29 women with no pain with intercourse. Two independent, structured pelvic floor examinations were carried out by physical therapists blind to the diagnostic status of the participants. Results indicated that therapists reached almost perfect agreement in their diagnosis of pelvic floor pathology. A series of significant correlations demonstrated the reliability of assessment results across muscle palpation sites. Women with VVS demonstrated significantly more vaginal hypertonicity, lack of vaginal muscle strength, and restriction of the vaginal opening, compared to women with no pain with intercourse. Anal palpation could not confirm generalized hypertonicity of the pelvic floor. We suggest that pelvic floor pathology in women with VVS is reactive in nature and elicited with palpations that result in VVS-type pain. Treatment interventions need to recognize the critical importance of addressing the conditioned, protective muscle guarding response in women with VVS.

Vulvar vestibulitis syndrome: reliability of diagnosis and evaluation of current diagnostic criteria.

OBJECTIVE: To assess the reliability of the diagnosis of vulvar vestibulitis as defined by Friedrich and to evaluate the usefulness of Friedrich's criteria in the diagnostic process. METHODS: In a university hospital, 146 women with dyspareunia had two sets of gynecologic examinations involving vulvar pain ratings, took part in structured interviews, and completed the McGill-Melzack Pain Questionnaire. RESULTS: Kappa values for the vulvar vestibulitis diagnosis ranged from 0.66 to 0.68 for inter-rater agreement and from 0.49 to 0.54 for test-retest reliability. Mean vestibular pain ratings ranged from 2.45 at the 12 o'clock site to 7.58 at the 9-12 o'clock site; ratings for all sites correlated significantly between gynecologists. Pain in the labia majora and labia minora was minimal for both sets of examinations, with mean participant pain ratings ranging from 0 to 1.49. Gynecologists' erythema ratings did not correlate significantly with respect to either inter-rater agreement or test-retest reliability. Of Friedrich's three diagnostic criteria, only tenderness to pressure within the vulvar vestibule differentiated dyspareunia patients with and without vulvar vestibulitis. In reference to their coital pain, 88.1% of women with vulvar vestibulitis chose adjectives from the McGill-Melzack Pain Questionnaire describing a thermal quality, and 86.6% chose adjectives describing an incisive pressure sensation. CONCLUSION: Vulvar vestibulitis can be reliably diagnosed in women with dyspareunia. Pain is limited to the vulvar vestibule and can be rated and described in a consistent fashion by these women. Erythema does not appear to be a useful diagnostic criterion.

The nature of human orgasm: a critical review of major trends.

This critical review presents a synthesis of the available theoretical and empirical literatures on human orgasm. Findings from both normal and clinical human populations are included. Two major trends in the literature, the dichotomization of biological and psychological perspectives and the assumption of gender differences, are highlighted. A new multidimensional model of the psychological experience of orgasm is described with a view to futhering a biopsychological approach applicable to both sexes. Clinical applications of this new model are discussed.

Structure of lifestyle disruptions in chronic disease: a confirmatory factor analysis of the Illness Intrusiveness Ratings Scale.

BACKGROUND: The Illness Intrusiveness Ratings Scale (IIRS) measures the extent to which disease or its treatment or both interfere with activities in important life domains. Before comparing IIRS scores within or across groups it is crucial to determine whether a common underlying factor structure exists across patient populations. OBJECTIVE: To investigate the factor structure underlying the IIRS and evaluate its stability across diagnoses. METHODS: IIRS responses from 5,671 respondents were pooled from 15 separate studies concerning quality of life in eight patient groups: rheumatoid arthritis; osteoarthritis; systemic lupus erythematosus; multiple sclerosis; end-stage renal disease (maintenance dialysis); renal transplantation; heart, liver, and lung transplantation; and insomnia. Data were gathered by different methods (eg, interview, self-administered, mail survey) and in diverse contexts (eg, individual vs. group). RESULTS: Exploratory maximum-likelihood factor analysis identified three underlying factors in a randomly selected subset of respondents (n = 400), corresponding to "Relationships and Personal Development," "Intimacy," and "Instrumental" life domains. Confirmatory factor analysis corroborated the stability of this structure in an independent subsample (n = 2100). Complementary goodness-of-fit indices confirmed the consistency of the three-factor solution, corroborating that IIRS scores are uniquely defined across patient populations. Coefficient alpha was high for total and subscale scores. CONCLUSIONS: IIRS scores can be compared meaningfully within and across patient groups. Both total and subscale scores can be used depending on research objectives.

Long-term knowledge retention following predialysis psychoeducational intervention.

BACKGROUND/AIMS: Early identification and predialysis psychoeducation are gaining acceptance. Although research supports the immediate value of predialysis interventions, long-term benefits remain unknown. We examined long-term knowledge retention following a psychoeducational intervention. METHODS: 47 progressive renal failure patients completed the Kidney Disease Questionnaire at baseline and 18, 30, 42, and 54 months after initiating renal replacement therapy (RRT; the 'longitudinal' sample). A larger cohort provided data at one or more of these points (n = 132, 117, 101, and 70 at 18, 30, 42, and 54 months, respectively; the 'cross-sectional' sample). RESULTS: Initial knowledge gains among psychoeducation recipients were followed by a significant knowledge advantage for three groups throughout follow-up. Patients who received predialysis psychoeducation either before or after starting dialysis demonstrated superior Kidney Disease Questionnaire scores as compared with those identified before the initiation of RRT who received the usual standard of practice. Patients identified after the initiation of RRT and who received standard education, however, demonstrated the same level of knowledge retention as produced by psychoeducation. The results were identical across the longitudinal and cross-sectional samples. CONCLUSIONS: Patient education produces important benefits in end-stage renal disease, but the incremental value of early intervention remains to be demonstrated.

Chronic fluoxetine inhibits sexual behavior in the male rat: reversal with oxytocin.

RATIONALE: Selective serotonin reuptake inhibitors, used widely in the treatment of depression, progressively inhibit sexual orgasm in many patients and induce a transient inhibition of sexual desire. OBJECTIVES: We attempted to model the effects of these drugs in sexually experienced male rats during tests of copulation in bilevel chambers. These chambers allow the study of both appetitive and consummatory sexual responses of male rats. METHODS: Males were treated daily with fluoxetine hydrochloride (0, 1, 5, or 10 mg/kg) and tested for sexual behavior with receptive females at 4-day intervals. Rats were treated with oxytocin (200 ng/kg) or saline after ejaculations had decreased. RESULTS: Fluoxetine decreased ejaculatory responses of male rats in a dose- and time-dependent fashion, but left the copulatory efficiency of the males intact. In contrast, conditioned level changing, a measure of appetitive sexual excitement, was inhibited following acute and chronic treatment with 10 mg/kg, although tolerance may have developed to the effect of 5 mg/kg. Subsequent administration of oxytocin restored the ejaculatory response but not the measure of sexual excitement to baseline levels. CONCLUSIONS: The reversal by oxytocin of the fluoxetine-induced deficit in ejaculations is consistent with the hypothesis that serotonin suppresses ejaculatory mechanisms by interrupting the action of oxytocin, which normally accompanies sexual behavior. Co-administration of oxytocin may help to alleviate the predominant sexual side effect of serotonin reuptake blockers.

Does vaginismus exist? A critical review of the literature.

The basic strategies and methods for assessing and treating vaginismus were proposed by the early 20th century and have not essentially changed. Etiological theories have changed over time but are not supported by controlled empirical studies. This critical review of the literature disputes the widely held belief that vaginismus is an easily diagnosed and easily treated sexual dysfunction. We propose a reconceptualization of vaginismus as either an aversion/phobia of vaginal penetration or a genital pain disorder.

Biopsychosocial profile of women with dyspareunia.

OBJECTIVE: To compare biopsychologic profiles of women with dyspareunia with a matched no-pain control sample, and to determine whether dyspareunia subtypes based on physical findings have different psychosocial profiles from matched controls. METHODS: One hundred and five women with dyspareunia and 105 matched no-pain control women underwent standard gynecologic examination, endovaginal ultrasound, and colposcopy. They also completed a structured interview inquiring about pain other than dyspareunia, sexual function, and history of abuse, the Brief Symptom Inventory, the Sexual Opinion Survey, and the Locke-Wallace Marital Adjustment Scale. RESULTS: In comparison with women who do not experience pain with intercourse, the dyspareunia sample was found to have more physical pathology on examination, and they reported more psychologic symptomatology, more negative attitudes toward sexuality, higher levels of impairment in sexual function, and lower levels of marital adjustment. They did not report more current or past physical or sexual abuse. However, when the undifferentiated dyspareunia sample was divided into subtypes based on physical findings from the gynecologic examinations, the pattern of significant differences from controls varied according to dyspareunia subtype. Elevated psychologic symptomatology and relationship maladjustment were confined to the subtype with no discernible physical findings who reported levels of sexual function not significantly different from matched controls. The vulvar vestibulitis subtype suffered the highest levels of sexual impairment, although this subtype was not characterized by higher levels of psychologic symptoms than controls. CONCLUSION: As an undifferentiated group, women with dyspareunia have more physical pathology, psychologic distress, sexual dysfunction, and relationship problems. However, this pattern of differences appears to vary depending on the presence and type of physical findings evident on examination. Dyspareunia is a heterogeneous disorder requiring comprehensive gynecologic and psychosocial assessment to determine differentiated treatment strategies.

The surgical treatment of vulvar vestibulitis syndrome: a follow-up study.

This study evaluated the effectiveness of vestibulectomy in relieving coital pain and improving sexual function in women diagnosed with vulvar vestibulitis. Vulvar vestibulitis syndrome, a chronic, nonspecific inflammation of the vulvar vestibule, probably represents the most frequent subtype of premenopausal dyspareunia. Participants were 38 women who underwent vestibulectomy at a university hospital between 1986 and 1994. Telephone interviews were conducted to assess whether vestibulectomy or other subsequent treatments affected coital pain and sexual functioning. Length of postoperative follow-up ranged from 1.1 to 10 years, with a mean of 3.3 years. Vestibulectomy yielded a positive outcome for 63.2% of the participants and moderate to no improvement for the other 36.8%. The surgery was linked to a significant increase in intercourse frequency for the entire sample and to an increase in oral and manual stimulation for the women with successful surgical outcomes. No other factors were significantly associated with treatment outcome.

Vulvar vestibulitis syndrome: a critical review.

OBJECTIVE: Vulvar vestibulitis syndrome (VVS) is thought to be the most frequent cause of dyspareunia in premenopausal women and is one of the major subtypes of vulvodynia. Vulvar vestibulitis is a chronic, persistent clinical syndrome characterized by severe pain on vestibular touch or attempted vaginal entry, exquisite tenderness to a cotton-swab palpation of the vestibular area, and physical findings confined to vestibular erythema. The purpose of this paper is to critically review the descriptive, diagnostic, etiologic, and treatment studies on VVS. Methodological problems are highlighted, and future guidelines for research are proposed. DATA SOURCES: References were obtained from a MEDLINE search covering the period from January 1984 until June 1995. The indexing term "vulvar vestibulitis" was used, and the search was constrained to English-language articles. References from other relevant sources, such as texts and bibliographies, were also included. STUDY SELECTION: All articles pertaining to VVS were reviewed. DATA EXTRACTION: All data relevant to the descriptive, diagnostic, etiologic, and treatment aspects of VVS were included. DATA SYNTHESIS: Pain symptomatology tends to be underemphasized in the current descriptive studies. The trend in etiological research is to focus on biomedical factors such as candidiasis and human papillomavirus (HPV). Only a few studies adopt a nonreductionnist approach. Surgery is the treatment option with the highest reported success rate. Medical management is underinvestigated, considering its widespread use. Pain management techniques such as biofeedback and behavior therapy show promising results. CONCLUSIONS: A pain syndrome conceptualization is suggested as the most useful approach for solving current empirical and clinical problems.

Dyspareunia: sexual dysfunction or pain syndrome?

This study investigated the clinical attributes of dyspareunia and the variables used to classify it. A systematic clinical description of the pain symptomatology was obtained through the administration of a structured interview and standardized pain measures to 112 women suffering from dyspareunia, ranging in age from 19 to 65. Subjects also underwent three different gynecological examinations and completed standardized measures of psychopathology, marital adjustment, and sexual attitudes, the results of which were used to test the ability of three different classification systems, including the DSM-IV, to predict physical and psychosocial outcomes. Using classification analysis, temporal pattern and location of the pain were found to be the best predictors of physical diagnoses, although none of the taxa in the three classification systems tested were related to psychosocial outcomes. Sexual impairment of women suffering from dyspareunia notwithstanding, the results support the consideration of dyspareunia as primarily a pain syndrome, rather than a sexual dysfunction.

Sexuality and end-stage renal disease: research and clinical recommendations.

Available studies of sexuality in end-stage renal disease (ESRD) patients are critically reviewed under three headings: (1) descriptive studies of dialysis patients, (2) intervention studies with dialysis patients, and (3) descriptive studies of renal transplant recipients. These studies suggest the presence of significant sexual deficits in uremic (predialysis) and dialysis patients that are only partially alleviated by transplantation or other medical interventions. There are no systematic evaluations of nonmedical interventions for sexual problems in ESRD patients. Most of the research has adopted a reductionist model of sexual behavior and suffers from poor methodology, unstandardized and incomplete measurement of sexual behavior, limited sample sizes, unrepresentative populations, an overemphasis on erectile problems, and a lack of attention to female sexuality. A holistic, biopsychosocial approach is recommended to guide further research and clinical work in this area.

Learning about sex outside the gutter: attitudes toward a computer sex-expert system.

In an ongoing research program investigating the utility of Sexpert, an expert computer system designed to counsel couples about their sexual relationships, we tested whether sexually active couples' attitudes concerning computerized sexual counseling could be affected by interacting with Sexpert. Eighty-one young heterosexual couples drawn from the university and general community were assigned to one of three sources of feedback about couple sexual functioning (Sexpert, a video, a self-help book) or a control condition. Attitudes toward all counseling sources used in the study were assessed through semantic differential and similarity-dissimilarity questionnaires. Subjects in the Sexpert condition showed significant improvements in their attitudes toward computerized sexual counseling and evaluated Sexpert significantly better and more similar to a human therapist as a result of exposure. Subjects in the other three conditions showed no significant changes in attitudes. This study provides strong evidence for the acceptability of a computerized sex-expert system.

Painful coitus: a review of female dyspareunia.

The literature on female dyspareunia is reviewed with an emphasis on description and classification, incidence and prevalence, etiological factors, and treatment approaches. The research is found to be plagued with methodological problems and characterized by a persistent dichotomization of issues into physiological and psychological categories. A systematized and integrated approach to the study of coital pain is proposed.

Body image and sexuality in oophorectomized women.

Five groups of women ages 35 to 55 years were studied, including a nonsurgical control group (CTL), a hysterectomy-only (HYS), and three oophorectomy groups: an untreated group (UNT), women on estrogen replacement therapy (EST), and women on androgen-estrogen replacement therapy (COM). The interview/questionnaire session assessed mood, body image, and sexual functioning. In a second session completed by 58 of 129 subjects (45%), a photoplethysmograph measured vaginal blood flow in response to an erotic stimulus while subjects concurrently monitored subjective arousal. Overall, the UNT and EST groups had significantly lower self-reported desire and arousal than the remaining three groups. Body image was significantly poorer in the UNT group. All surgical groups reported more sexual problems than the control group. Furthermore, about a third of the CTL group reported positive changes in body image and sexuality in the previous 5 years. This effect was attenuated in the HYS, COM, and EST groups and almost absent in the UNT group. No significant group differences were obtained, however, on mood or vaginal blood flow and subjective arousal to an erotic stimulus. The role of differential levels of testosterone on sexuality is discussed as well as its clinical implications.
