RESUMO

RATIONALE AND OBJECTIVE: The aim of this study was to investigate the possible facilitating effect of the partial NMDA receptor agonist D-cycloserine (DCS) on memory consolidation of conditioned sexual responses and to examine the capability of DCS to reduce context-specificity of learning. METHODS: In a randomized placebo-controlled double-blind trial, 50 healthy females were exposed to a differential conditioning procedure. Two pictures of a male abdomen were used as conditional stimuli (CSs), of which one (the CS+) was followed by the unconditional stimulus (US), a genital vibrotactile stimulus. After the conditioning session on day 1, participants received either 125 mg of DCS or a placebo. The effects of DCS on affect, sexual arousal and US expectancy in response to the CS+ and CS- were examined 24 h after the conditioning procedure. RESULTS: A main effect of DCS was found on affect at the first test trials (p = 0.04, ηp2 = 0.09), and a similar non-significant but trend level effect was found for sexual arousal (p = 0.06, ηp2 = 0.07), which appeared to persist over a longer time (p = 0.07, ηp2 = 0.08). Unexpectedly, ratings of positive affect and sexual arousal in response to both the CS+ and the CS- were higher in the DCS condition compared to the control condition, possibly indicating that DCS administration reduced stimulus specificity. Since the results did not show clear evidence for context learning, we were not able to test effects on context-specificity of learning. CONCLUSION: Although largely inconclusive, the results provide tentative support for a facilitating effect of DCS on affect and sexual arousal in response to stimuli that were presented in a sexual conditioning procedure, however, no conclusions can be drawn about effects of DCS on sexual reward learning, since the design and results do not lend themselves to unambiguous interpretation.

RESUMO

STUDY QUESTION: Do sexual functioning, sexual esteem, genital self-image and psychological and relational functioning in women with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome differ from a comparison group of women without the condition? SUMMARY ANSWER: In comparison to controls, women with MRKH with a non-surgically or surgically created neovagina did not differ in psychological and relational functioning but reported lower sexual esteem and more negative genital self-image, intercourse-related pain, clinically relevant sexual distress and sexual dysfunction, with sexual esteem levels strongly associated with sexual distress and sexual dysfunction. WHAT IS KNOWN ALREADY: Studies on sexual functioning measured with standardized questionnaires in women with MRKH syndrome compared with women without the condition have yielded contradictory results. Factors associated with sexual functioning in this patient population have rarely been investigated. STUDY DESIGN, SIZE, DURATION: Between November 2015 and May 2017, 54 women with MRKH syndrome with a neovagina and 79 age-matched healthy women without the condition were enrolled in this case-control study. PARTICIPANTS/MATERIALS, SETTING, METHODS: All participants had to be at least 18-years old and had to live in a steady heterosexual relationship. Women with MRKH syndrome were asked to participate by their (former) gynecologists at three university hospitals and by MRKH peer support group. Controls were recruited via advertisement in local newspapers and social media. Standardized questionnaires were administered to assess sexual functioning, sexual esteem, genital self-image and psychological and relational functioning. MAIN RESULTS AND THE ROLE OF CHANCE: Women with MRKH syndrome with a surgically or non-surgically created neovagina reported significantly more pain during intercourse (P < 0.05, d = 0.5), but did not differ in overall sexual functioning from control women. More women with MRKH syndrome reported clinically relevant sexuality-related distress (P < 0.05, odds ratio (OR): 2.756, 95% CI 1.219-6.232) and suffered a sexual dysfunction (P < 0.05, OR: 2.654, 95% CI: 1.088-6.471) in comparison with controls. MRKH women scored significantly lower on the sexual esteem scale (SES) (P < 0.01, d = 0.5) and the female genital self-image scale (FGSIS) (P < 0.01, d = 0.6) than controls. No significant differences were found between the two groups regarding psychological distress, anxiety and depression, global self-esteem and relational dissatisfaction. Sexual esteem was significantly associated with the presence of clinically relevant sexual distress (ß = 0.455, P = 0.001) and suffering a sexual dysfunction (ß = 0.554, P = 0.001) and explained, respectively, 40% and 28% of the variance. LIMITATIONS, REASONS FOR CAUTION: Given the nature of the study focusing on sexual functioning, a potential selection bias cannot be excluded. It is possible that those women with the most severe sexual and/or psychological disturbances did or did not choose to participate in our study. WIDER IMPLICATIONS OF THE FINDINGS: The study results add new data to the very limited knowledge about psychosexual functioning of women with MRKH syndrome and are of importance for more adequate counseling and treatment of these women. STUDY FUNDING/COMPETING INTEREST(S): The research was financially supported by the Dutch Scientific Society of Sexology (Nederlandse wetenschappelijke Vereniging Voor Seksuologie). The funding was unrestricted, and there was no involvement in the conduct of the research. There are no conflicts of interest to declare.

RESUMO

BACKGROUND: Patients with Barrett's esophagus (BE) usually have severe gastroesophageal reflux. However, they often have surprisingly few reflux symptoms. We hypothesized that BE patients are less sensitive to acid than gastroesophageal reflux disease (GERD) patients without Barrett and that this is due to an unusual preservation of mucosal integrity of the squamous epithelium prohibiting transepithelial acid diffusion. METHODS: We prospectively analyzed esophageal sensitivity and esophageal mucosal integrity in GERD patients with and without BE and healthy subjects. An acid perfusion test was performed and mucosal integrity was assessed in vivo by electrical tissue impedance spectroscopy and ex vivo by Ussing chamber experiments with biopsy specimens. KEY RESULTS: Gastroesophageal reflux disease patients with BE were less sensitive to acid than GERD patients without BE, but more sensitive to acid than healthy controls (time to perception Barrett's 14.0 minutes, GERD 4.6 minutes, controls 17.5 minutes). However, extracellular impedance (6.2 and 5.7 vs 8.4×103  Ω/m) and transepithelial resistance (94.0 and 89 vs 118 Ω/cm2 ) was similar in BE and GERD patients and significantly lower than in healthy subjects. Transepithelial fluorescein flux was equally increased in GERD patients with and without BE (1.6 and 1.7×103 vs 0.6×103  nmol/cm2 /h). CONCLUSIONS & INFERENCES: Esophageal hypersensitivity to acid is less pronounced in BE patients than in GERD patients without Barrett. However, mucosal integrity of the squamous epithelium is equally impaired in GERD patients with and without Barrett, indicating that factors other than esophageal mucosal barrier integrity explain the difference in acid sensitivity between those with BE and those without.

RESUMO

BACKGROUND: Patients with functional heartburn (FH) experience troublesome heartburn that is not related to gastroesophageal reflux. The etiology of the heartburn sensation in FH patients is unknown. In patients with reflux disease, esophageal hypersensitivity seems associated with impaired mucosal integrity. We aimed to determine esophageal sensitivity and mucosal integrity in FH and non-erosive reflux disease (NERD) patients. METHODS: In this prospective experimental study, we performed an acid perfusion test and upper endoscopy with biopsies in 12 patients with NERD and nine patients with FH. Mucosal integrity was measured during endoscopy using electrical tissue impedance spectroscopy and biopsy specimens were analyzed in Ussing chambers for transepithelial electrical resistance and transepithelial permeability. KEY RESULTS: Lag time to heartburn perception was significantly longer in FH patients (median 12 min) than in NERD patients (median 3 min). Once perceived, intensity of heartburn was scored equal with median visual analog scale 6.5 and 7.1 respectively. Esophageal mucosal integrity was also comparable between FH and NERD patients, both in vivo extracellular impedance and ex vivo transepithelial resistance and permeability were similar. CONCLUSIONS & INFERENCES: Patients with FH did not show acid hypersensitivity as seen in patients with NERD. However, once perceived, intensity of heartburn is similar. Esophageal mucosal integrity is similar between NERD and FH patients, and is therefore unlikely to be the underlying cause of the observed difference in esophageal acid perception.

RESUMO

BACKGROUND: In patients with typical reflux symptoms that persist despite proton pump inhibitors (PPIs) it is sometimes overlooked that treatment fails due to the presence of other disorders than gastroesophageal reflux disease (GERD). The aim of this study was to determine the underlying cause of reflux symptoms not responding to PPI therapy in tertiary referral patients. METHODS: Patients with reflux symptoms refractory to PPI therapy who underwent 24-h pH-impedance monitoring were analyzed. Patients in whom a diagnosis was already established before referral, who had previous esophageal or gastric surgery, or who had abnormalities on gastroscopy other than hiatus hernia, were excluded. KEY RESULTS: In total, 106 patients were included. Esophageal manometry showed achalasia in two patients and distal esophageal spasm in another two. Twenty-four-hour pH-impedance monitoring revealed a total acid exposure time <6% in 60 patients (56.6%) of which 25 had a positive symptom association probability (SAP) while 35 showed a negative SAP. Sixty-nine patients ended up with a final diagnosis of GERD while 32 patients (30.2%) were diagnosed with functional heartburn (FH), two with functional chest pain, two with achalasia, and one with rumination. A trend toward an association with a final diagnosis of FH was found with the atypical symptom epigastric pain (p = 0.059) and with a secondary diagnosis of functional dyspepsia (p = 0.083). CONCLUSIONS & INFERENCES: Approximately one-third of the patients referred with refractory reflux symptoms suffer from disorders other than GERD, predominantly FH. This explains, at least partly, why many patients will not benefit from acid inhibitory treatment.

RESUMO

BACKGROUND: Fundoplication is an effective therapy for gastroesophageal reflux disease (GERD), but can be complicated by postoperative dysphagia. High-resolution manometry (HRM) can assess esophageal function, but normal values after fundoplication are lacking. Our aim was to obtain normal values for HRM after successful Toupet and Nissen fundoplication. METHODS: Esophageal HRM was performed 3 months after Toupet or Nissen fundoplication in 40 GERD patients without postoperative dysphagia and with a normal barium esophagogram. Normal values for all measures of the Chicago classification were calculated as 5th and 95th percentile ranges. KEY RESULTS: The normal values (5th-95th percentiles) for integrated relaxation pressure (IRP) were higher after Nissen (5.1-24.4 mmHg) than after Toupet fundoplication (3.1-15.0 mmHg), and upper limit of normal was significantly higher after Nissen fundoplication than observed in the asymptomatic subjects that were described in the Chicago Classification. Distal contractile integral was significantly higher after Nissen (357-4947 mmHg*s*cm) than after Toupet (68-2177 mmHg*s*cm), and transition zone length was significantly shorter after Nissen (0-4.8 cm) than after Toupet fundoplication (0-12.8 cm). CONCLUSIONS & INFERENCES: HRM metrics for subjects after a Toupet fundoplication are similar to the normal values derived from healthy subjects used for the Chicago classification. However, after Nissen fundoplication a higher esophagogastric junction resting pressure and higher IRP are observed in asymptomatic subjects and this can be considered normal in the postoperative state. In addition, more vigorous contractions and less and smaller peristaltic breaks are normal after Nissen fundoplication.

RESUMO

BACKGROUND: The diagnosis of a sliding hiatal hernia is classically made with endoscopy or barium esophagogram. Spatial separation of the lower esophageal sphincter (LES) and diaphragm, the hallmark of hiatal hernia, can also be observed on high-resolution manometry (HRM), but the diagnostic accuracy of this finding has not yet been investigated. To determine the diagnostic value of HRM in the detection of hiatal hernia. METHODS: HRM recordings, endoscopy reports, and barium esophagograms of 90 patients were analyzed for the presence and size of a hiatal hernia. The diagnostic value of a hernia specific HRM pressure pattern was calculated, and the agreement of HRM with endoscopy and barium esophagogram for the assessment of hernia size. KEY RESULTS: HRM was found to be highly sensitive and specific for hiatal hernia detection, with a sensitivity of 92% and specificity of 95%, exceeding the sensitivity of endoscopy or radiography alone (both 73%). Patients with a hiatal hernia on HRM were manometrically characterized by an esophagogastric junction (EGJ) with partial or complete separation of the LES and crural diaphragm (CD), the latter being associated with significantly lower EGJ pressure. A cutoff value of spatial LES-CD separation on HRM of 1.85 cm yielded the optimal performance in identifying hiatal hernia. Agreement between HRM, endoscopy, and radiography for size of hiatal hernias was good (ICC [95% CI] 0.74 [0.65-0.82]). CONCLUSIONS & INFERENCES: With HRM, the presence or absence and size of a hiatal hernia can be assessed with greater sensitivity than with endoscopy or radiography alone.

RESUMO

High-resolution esophageal manometry (HRM) is a recent development used in the evaluation of esophageal function. Our aim was to assess the inter-observer agreement for diagnosis of esophageal motility disorders using this technology. Practitioners registered on the HRM Working Group website were invited to review and classify (i) 147 individual water swallows and (ii) 40 diagnostic studies comprising 10 swallows using a drop-down menu that followed the Chicago Classification system. Data were presented using a standardized format with pressure contours without a summary of HRM metrics. The sequence of swallows was fixed for each user but randomized between users to avoid sequence bias. Participants were blinded to other entries. (i) Individual swallows were assessed by 18 practitioners (13 institutions). Consensus agreement (≤ 2/18 dissenters) was present for most cases of normal peristalsis and achalasia but not for cases of peristaltic dysmotility. (ii) Diagnostic studies were assessed by 36 practitioners (28 institutions). Overall inter-observer agreement was 'moderate' (kappa 0.51) being 'substantial' (kappa > 0.7) for achalasia type I/II and no lower than 'fair-moderate' (kappa >0.34) for any diagnosis. Overall agreement was somewhat higher among those that had performed >400 studies (n = 9; kappa 0.55) and 'substantial' among experts involved in development of the Chicago Classification system (n = 4; kappa 0.66). This prospective, randomized, and blinded study reports an acceptable level of inter-observer agreement for HRM diagnoses across the full spectrum of esophageal motility disorders for a large group of clinicians working in a range of medical institutions. Suboptimal agreement for diagnosis of peristaltic motility disorders highlights contribution of objective HRM metrics.

RESUMO

BACKGROUND: The Chicago Classification (CC) facilitates interpretation of high-resolution manometry (HRM) recordings. Application of this adult based algorithm to the pediatric population is unknown. We therefore assessed intra and interrater reliability of software-based CC diagnosis in a pediatric cohort. METHODS: Thirty pediatric solid state HRM recordings (13M; mean age 12.1 ± 5.1 years) assessing 10 liquid swallows per patient were analyzed twice by 11 raters (six experts, five non-experts). Software-placed anatomical landmarks required manual adjustment or removal. Integrated relaxation pressure (IRP4s), distal contractile integral (DCI), contractile front velocity (CFV), distal latency (DL) and break size (BS), and an overall CC diagnosis were software-generated. In addition, raters provided their subjective CC diagnosis. Reliability was calculated with Cohen's and Fleiss' kappa (κ) and intraclass correlation coefficient (ICC). KEY RESULTS: Intra- and interrater reliability of software-generated CC diagnosis after manual adjustment of landmarks was substantial (mean κ = 0.69 and 0.77 respectively) and moderate-substantial for subjective CC diagnosis (mean κ = 0.70 and 0.58 respectively). Reliability of both software-generated and subjective diagnosis of normal motility was high (κ = 0.81 and κ = 0.79). Intra- and interrater reliability were excellent for IRP4s, DCI, and BS. Experts had higher interrater reliability than non-experts for DL (ICC = 0.65 vs ICC = 0.36 respectively) and the software-generated diagnosis diffuse esophageal spasm (DES, κ = 0.64 vs κ = 0.30). Among experts, the reliability for the subjective diagnosis of achalasia and esophageal gastric junction outflow obstruction was moderate-substantial (κ = 0.45-0.82). CONCLUSIONS & INFERENCES: Inter- and intrarater reliability of software-based CC diagnosis of pediatric HRM recordings was high overall. However, experience was a factor influencing the diagnosis of some motility disorders, particularly DES and achalasia.

RESUMO

BACKGROUND: The Chicago classification for esophageal motility disorders was designed for a 36-channel manometry system with sensors spaced at 1 cm. However, many motility laboratories outside the USA use catheters with a lower resolution in the segments outside the esophagogastric junction. Our aim was to investigate the effect of spatial resolution on the Chicago metrics and diagnosis. METHODS: In 20 healthy volunteers and 47 patients with upper gastrointestinal symptoms, high-resolution manometric studies of the esophagus were retrospectively reanalyzed using the original 1-cm spacing in the segments outside the 7-cm esophagogastric junction segment, and again after manually increasing the spacing between sensors to 2, 3, and 4 cm (above the lower esophageal sphincter region). Measurements were analyzed in random order and the investigator was blinded to the outcome of the analyses performed in another resolution of the same patient. Intra-class correlation coefficients (ICC) and Kappa values were determined. KEY RESULTS: There was a very strong correlation between the 1-cm and 2-cm analysis for all Chicago metrics studied in healthy volunteers (ICCs: distal contractile integral 0.998; contractile front velocity (CFV) 0.964; distal latency 0.919; peristaltic break size 0.941). The 2-cm spacing analysis also correlated very well with the 1-cm analysis for the different Chicago diagnoses obtained in the patients (Kappa values ranging from 0.665 to 1.000). When the sensor spacing was increased to 3 and 4 cm, the correlation was reduced to moderate for the Chicago metrics, especially for break size and CFV of peristalsis. CONCLUSIONS & INFERENCES: The Chicago classification for esophageal motility disorders is still valid and the same normal values can be used when catheters with a slightly lower resolution are used (i.e., 2-cm vs 1-cm spacing). For larger sensor intervals, the classification and the normal values will need to be adjusted.

RESUMO

BACKGROUND: Esophageal high-resolution manometry (HRM) allows accurate evaluation of esophageal motility. Normal values for HRM were established in the United States and several new parameters were introduced since. We aimed to provide a complete set of normal values for HRM obtained in a European population, including all current metrics used to describe the function of the upper esophageal sphincter (UES), the esophageal body, and the esophagogastric junction (EGJ). METHODS: Fifty healthy volunteers underwent esophageal HRM. Subjects swallowed 10 liquid boluses in supine position, after which UES, EGJ, and contraction wave parameters were evaluated. Mean and median values with 5-95th percentile ranges were calculated. KEY RESULTS: The normative thresholds (5-95th percentile) for the various parameters were; UES resting pressure 34.6-137.7 mmHg, UES residual pressure 0.0-8.5 mmHg, UES 0.2-s integrated relaxation pressure (IRP) 0.0-14.5 mmHg, EGJ length 3.1-6.3 cm, EGJ resting pressure 3.0-31.2 mmHg, EGJ 4-s IRP 2.0-15.5 mmHg, intrabolus pressure (IBP) 6.6-19.5 mmHg, distal contractile integral 178-2828 mmHg*s*cm, contractile front velocity (CFV) 2.9-5.9 cm s(-1) , distal latency 5.4-8.5 s, and transition zone length 0.0-8.2 cm. CONCLUSIONS & INFERENCES: Most HRM parameters assessed in this study resemble the previously described values on which the current criteria are based, supporting the widespread use of these criteria for clinical purposes. However, vigor of the esophageal contraction was lower and transition zone length larger than in previous reports. Peristaltic breaks occur frequently in healthy subjects.

RESUMO

BACKGROUND: Patients with gastroesophageal reflux disease (GERD) have impaired esophageal mucosal integrity. Measurement of the mucosal integrity is complex and time-consuming. Electrical tissue impedance spectroscopy (ETIS) is a device that measures impedance of tissue in vivo during endoscopy. In this study, we aimed to validate ETIS as a measure of esophageal mucosal integrity. METHODS: Electrical tissue impedance spectroscopy measurements were performed during upper endoscopy in 12 GERD patients and 11 healthy controls after cessation of proton pump inhibition. During endoscopy biopsies of the distal esophagus were obtained for transmission electron microscopy to determine dilation of intercellular spaces (DIS) and for Ussing chamber experiments to determine transepithelial permeability and transepithelial electrical resistance. KEY RESULTS: Extracellular impedance measured in vivo by ETIS was significantly lower in GERD patients compared to controls [mean (SD) 5621 (3299) Ω.m and 8834 (2542) Ω.m, respectively, P < 0.05]. We found a strong inverse relation between extracellular impedance determined by ETIS and DIS (r = -0.76, P < 0.05), and between extracellular resistance in vivo and transepithelial permeability of esophageal biopsies (r = -0.65, P < 0.01). CONCLUSIONS & INFERENCES: Electrical tissue impedance spectroscopy is a new tool that can be used to evaluate esophageal mucosal integrity changes during endoscopy.

RESUMO

BACKGROUND: Symptomatic response to proton pump inhibitor (PPI) therapy in patients with non-erosive reflux disease (NERD) is often reported as lower than in patients with erosive reflux disease (ERD). However, the definition of NERD differs across clinical trials. This meta-analysis aims to estimate the rate of symptom relief in response to PPI in NERD patients. METHODS: MEDLINE (1966-2010), Cochrane Comprehensive Trial Register (1997-2010) and EMBASE (1985-2010) databases were searched and manual searches from studies' references were performed. Randomized clinical trials were selected that included patients with heartburn, and analyzed the effect of short-term PPI treatment. The primary outcome of selected studies was defined as complete or partial heartburn relief. Two reviewers independently extracted data and assessed study quality of selected articles. Random effects models and meta-regression were used to combine and analyze results. KEY RESULTS: The pooled estimate of complete relief of heartburn after 4 weeks of PPI therapy in patients with ERD was 0.72 (95% CI 0.69-0.74) (32 studies), vs 0.50 (0.43-0.57) (eight studies) in empirically treated patients, 0.49 (0.44-0.55) (12 studies) in patients defined as non-erosive by negative endoscopy, and 0.73 (0.69-0.77) (two studies) in patients defined as non-erosive by both negative endoscopy and a positive pH-test. CONCLUSIONS & INFERENCES: In well-defined NERD patients, the estimated complete symptom response rate after PPI therapy is comparable to the response rate in patients with ERD. The previously reported low response rate in studies with patients classified as NERD is likely the result of inclusion of patients with upper gastrointestinal symptoms that do not have reflux disease.

RESUMO

OBJECTIVE: To compare sexual functioning and distress in women with systemic sclerosis (SSc) with that in healthy controls and determine the association between disease characteristics and sexual function. METHODS: We conducted a cross-sectional study of 69 women with SSc (ages 18-60 years) and 58 healthy, age-matched controls. Assessment included the Female Sexual Function Index (FSFI), Female Sexual Distress Scale (FSDS), Hospital Anxiety and Depression Scale, Short Form 36 health survey, sociodemographic characteristics, and in patients only, the Health Assessment Questionnaire. RESULTS: Of 69 eligible patients with SSc, 37 (54%) responded, in addition to 37 (64%) of 58 controls. The FSFI total score and the subscale scores for lubrication, orgasm, arousal, and pain were significantly lower and the FSDS scores were significantly higher in patients with SSc. Longer disease duration and higher levels of marital dissatisfaction were significantly associated with low sexual function in patients with SSc. Longer disease duration, more depressive symptoms, and the use of antidepressants were significantly associated with sexual distress. Multivariate analyses indicated that marital distress was the only variable significantly associated with low sexual function in patients with SSc (beta = 0.40, P < 0.05), whereas depression was the only variable significantly associated with sexual distress (beta = 0.32, P < 0.05). The same pattern of associations was found in the healthy control group. CONCLUSION: Women with SSc reported significantly impaired sexual functioning and more sexual distress then healthy controls. Impaired sexual functioning and sexual distress were associated with marital distress and depressive symptoms. These results indicate that in daily practice, inquiring about sexuality and screening for depressive symptoms is indicated in every patient with SSc, irrespective of their clinical characteristics.

RESUMO

The consequences of a history of sexual abuse for pregnancy and delivery are illustrated in case histories of three women, aged 28, 27 and 31 years respectively. The first woman (who had a history of sexual abuse, like the other women) reacted to labour with dissociative behaviour. This was anticipated by giving her directions for the proceedings during labour, which helped restoring contact. The second patient expressed insecurity during her prenatal check-ups, the reaction to which was inadequate. When labour started her fear had grown and led to an early plea for a caesarean section. An epidural made caesarean section redundant. The third patient had re-experiences during her prenatal check-ups. External examination or an ultrasound were a burden to her. Together with the patient a detailed treatment plan was made which gave her control over the situation. It is advised to question all women during prenatal care about a possible history of sexual abuse and if found, to discuss the consequences of these experiences in her everyday life, especially during her pregnancy. The obstetrical care-giver has to be aware of the circumstances that might provoke traumatic memories and anxious feelings. By knowing and anticipating these events--also called triggers--, the professional can give 'tailor-made' care during pregnancy and delivery.

RESUMO

The purpose of this exploratory study was to identify clinical similarities and differences in patients with vaginismus and dyspareunia. Thirty patients who were referred to an outpatient clinic for psychosomatic gynecology and sexology, with either of these two diagnoses, were investigated by means of a standardized interview, physical examination and self-rating questionnaires. Based on the interview, no significant differences were demonstrated between patients with vaginismus and dyspareunia, in the ability to insert a finger into the vagina or to have a gynecological examination. No differences were found in the reported level of pain during coitus (or attempted coitus), inserting one finger into the vagina, or during gynecological examination. Patients with vaginismus, however, more often reported that coitus was impossible. The physical examination and self-rating questionnaires showed no differences at all between patients with vaginismus and dyspareunia in palpated vaginal muscular tension and reported anxiety or tension during the examination. Moreover, in both groups redness and painful areas on the vulva were equally common. Redness and pain on the same location were more frequently present in the dyspareunia group. Patients with dyspareunia reported higher levels of pain during the examination. In conclusion, neither the interview nor the physical examination produced useful criteria to distinguish vaginismus from dyspareunia. A multi-axial description of these syndromes is suggested, rather than viewing them as two separate disorders.

RESUMO

OBJECTIVE: To evaluate the effect of a group programme on psychological distress in women with the Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome. SETTING: Gynaecologic outpatient clinic. SAMPLE: Seventeen women with MRKH syndrome participated in this study. METHOD: A semi-structured programme of seven sessions was offered dealing with themes of the MRKH syndrome. Psychological distress was measured at the first visit 3-6 month before the group programme was started (pre-test-0), at the first (pre-test) and then at the last group session (post-test). MAIN OUTCOME MEASURE: The Symptom Check List-90 was used to assess feelings of psychological distress. RESULTS: The post-test subscale scores for anxiety, depression, interpersonal sensitivity and the total score for psychological distress were significantly lower than the pre-test-0 and pre-test scores (P < 0.05). No significant differences were found between the pre-test-0 and pre-test subscale scores and total score. CONCLUSION: A semi-structured group programme seems valuable in helping women with the MRKH syndrome to deal with their psychological stress.

RESUMO

OBJECTIVE: To determine the frequency of sexual difficulties and of sexual and physical abuse. DESIGN: Descriptive survey study. SETTING: Outpatient gynaecology clinic of the University Hospital of Leiden, the Netherlands. PATIENTS AND METHOD: During 3 months, December 1994-February 1995, all consecutive new female patients were questioned by the gynaecologist by means of a short standardised questionnaire. Oncology patients and non-Dutch-speaking patients were excluded. Data were analysed with descriptive statistical procedures; relationships among variables were tested with the chi 2 test with Yates' correction or Fisher's exact test. RESULTS: Of 325 patients 34.2% reported sexual difficulties, 15.4% reported sexual abuse and 7.4% physical molestation. Age of the patient and presence or absence of the partner during the consultation were not associated with differences in the patients' reports. 18.8% of the patients with these complaints answered affirmatively when asked if they needed specialised help. CONCLUSION: Sexual difficulties and sexual and physical abuse were common among gynaecology patients. Less than one-fifth of them required specialised help.

RESUMO

OBJECTIVE: To compare psychologic profiles of women with vulvar vestibulitis and their partners with a normal population, and to identify sexual dysfunction in women and their partners. METHODS: Forty-three women with vulvar vestibulitis and 38 partners, recruited from a gynecology outpatient clinic, completed the Symptom Check List-90, the Short Dutch Version of the Minnesota Multiphasic Personality Inventory, the Maudsley Marital Questionnaire, and the Questionnaire for Screening Sexual Dysfunctions. RESULTS: The women with vulvar vestibulitis scored significantly higher on the somatization and shyness subscales than a normal population. They didn't differ in respect to their current level of psychologic distress, extraversion, risk of psychopathology, and marital satisfaction. Their partners had significantly lower scores for psychopathology than a normal population. They didn't differ from a normal population in respect to their level of psychologic distress, extraversion, shyness, somatization, and marital satisfaction. Women with vulvar vestibulitis reported more frequent problems and higher distress with genital pain, lubrication, sexual arousal, and negative emotions in the sexual interaction with the partner. During masturbation, however, they reported less frequent problems and distress. The partners of these women reported nearly no problems or distress in either sexual situation. CONCLUSION: Women with vulvar vestibulitis and their partners seem in general to be psychologically healthy, although vulvar vestibulitis may be associated with a situationally defined sexual dysfunction for the women.

RESUMO

This retrospective study was undertaken to investigate predictors of vaginismus, dyspareunia and mixed sexual pain disorder in respect of symptom profile and treatment history variables of female patients and their partners. The study sample consisted of 147 female patients attending a university hospital outpatient clinic for Psychosomatic Gynecology and Sexology. All patients met the DSM-III-R criteria of the diagnoses of vaginismus (n = 50), dyspareunia (n = 46), or of both diagnoses (n = 51). No univariate differences were found between members of the three groups or between their partners. It was not possible to make a multivariate prediction of group membership.
