Patient Characteristics by Type of Hypersexuality Referral: A Quantitative Chart Review of 115 Consecutive Male Cases.

Hypersexuality remains an increasingly common but poorly understood patient complaint. Despite diversity in clinical presentations of patients referred for hypersexuality, the literature has maintained treatment approaches that are assumed to apply to the entire phenomenon. This approach has proven ineffective, despite its application over several decades. The present study used quantitative methods to examine demographic, mental health, and sexological correlates of common clinical subtypes of hypersexuality referrals. Findings support the existence of subtypes, each with distinct clusters of features. Paraphilic hypersexuals reported greater numbers of sexual partners, more substance abuse, initiation to sexual activity at an earlier age, and novelty as a driving force behind their sexual behavior. Avoidant masturbators reported greater levels of anxiety, delayed ejaculation, and use of sex as an avoidance strategy. Chronic adulterers reported premature ejaculation and later onset of puberty. Designated patients were less likely to report substance abuse, employment, or finance problems. Although quantitative, this article nonetheless presents a descriptive study in which the underlying typology emerged from features most salient in routine sexological assessment. Future studies might apply purely empirical statistical techniques, such as cluster analyses, to ascertain to what extent similar typologies emerge when examined prospectively.

Exploring the neural correlates of touch and pain in women with provoked vestibulodynia.

Group differences in touch and pain thresholds-and their neural correlates-were studied in women with provoked vestibulodynia (PVD; N = 15), a common subtype of vulvodynia (chronic vulvar pain), and pain-free control women (N = 15). Results from quantitative sensory testing and self-report measures indicated that, as compared with control participants, women with PVD exhibited allodynia (ie, pain in response to a normally nonpainful stimulus) and hyperalgesia (ie, an increased response to a normally painful stimulus) at vulvar and nonvulvar sites. In addition, brain imaging analyses demonstrated reduced difference scores between touch and pain in the S2 area in women with PVD compared with control participants, supporting previous findings of allodynia in women with PVD. There were no significant reductions in difference scores between touch and pain for regions related to cognitive and affective processing of painful stimuli. The results of this study contribute important information to the general pain and vulvodynia literatures in elucidating the specific sensorimotor neural mechanisms that underlie hyperalgesia in a chronic pain population. These results have implications for differentiating neural processing of touch and pain for women with and without PVD. Future research should attempt to examine alterations related to hyperalgesia in commonly comorbid conditions of PVD.

Pain, psychosocial, sexual, and psychophysical characteristics of women with primary vs. secondary provoked vestibulodynia.

INTRODUCTION: Women with provoked vestibulodynia (PVD), a common cause of dyspareunia, are typically considered a homogeneous group. However, research suggests that differences on some factors (e.g., medical history, pain characteristics, psychological functioning, treatment response) exist based upon whether the pain was present at first intercourse (primary PVD: PVD1) or developed at some later point (secondary PVD: PVD2). AIMS: The purpose of this study was to examine differences in demographic variables, pain characteristics, psychosocial and psychosexual adjustment, and pain sensitivity between women with PVD1 and PVD2. METHODS: Twenty-six women suffering from PVD (13 with PVD1 and 13 with PVD2) completed a screening assessment, a standardized gynecological examination, an interview, questionnaires, and a quantitative sensory testing session. MAIN OUTCOME MEASURES: These included pain ratings during the gynecological examination and interview, scores on measures of psychosocial/sexual functioning (e.g., Short Form-36 [SF-36] Health Survey, Female Sexual Function Index), and thresholds and pain ratings during thermal sensory testing over the dominant forearm and vulvar vestibule. RESULTS: The women with PVD1 were more likely to be nulliparous, but they were not significantly different from the women with PVD2 on other demographic variables or in their pain ratings during the gynecological examination. The women with PVD1 reported lower levels of social and emotional functioning and heightened anxiety surrounding body exposure during sexual activity, and they also displayed lower heat pain tolerance over the forearm and lower heat detection and pain thresholds at the vulvar vestibule than the women with PVD2. CONCLUSIONS: The findings from this study support previous research indicating that women with PVD1 and PVD2 differ in a number of domains. Further research is needed to confirm and elaborate on these findings.

Pain ratings, sensory thresholds, and psychosocial functioning in women with provoked vestibulodynia.

Psychosocial and psychophysical functioning in 25 women with and 25 without provoked vestibulodynia (PVD) were examined. Participants underwent quantitative sensory testing and completed psychosocial measures. Women with PVD displayed lower pain thresholds, higher pain ratings, lower sexual functioning and sexual self-efficacy, and higher levels of somatization and catastrophization than controls. Lower psychosocial functioning correlated with decreased vulvar pressure-pain threshold and increased cotton-swab test pain ratings. For PVD women, decreased sexual function and sexual self-efficacy were associated with higher vulvar pressure-pain ratings. Findings suggest that women with PVD would benefit from treatment that addresses pain-focused and psychosocial components.

The vulvalgesiometer as a device to measure genital pressure-pain threshold.

The construction and application of the vulvalgesiometer are described. This manually-applied device allows for the quantifiable measurement of pressure-pain thresholds in the external female genital region. A set of five vulvalgesiometers exerting pressures from 3 to 950 g was used in two studies. The goal of the first study was to examine the ability of the vulvalgesiometers to discriminate between women with and without provoked vestibulodynia (PVD). In a matched sample of affected and non-affected women, women with PVD exhibited significantly lower vestibular pressure-pain thresholds as compared to control women. As well, approximately half the sample of women with PVD described the sensation elicited at pressure-pain threshold as similar to the pain experienced during sexual intercourse. The goal of the second study was to investigate the inter-rater reliability of the vulvalgesiometers. In this separate sample of women with and without PVD, each participant was tested for pressure-pain threshold by two different investigators at different times. Results demonstrated high levels of inter-rater reliability, indicating that the vulvalgesiometers can be consistently used by different investigators. Further, results indicated significant negative correlations between pressure-pain thresholds and pain intensity ratings recorded during the cotton-swab test, suggesting that the lower the threshold, the higher the pain ratings during vestibular palpation. The vulvalgesiometers can be utilized for several purposes, including treatment outcome studies and measuring the degree of PVD severity.
