Filter by:In this study we will investigate the efficacy and safety of infiltration of the vestibulum vaginae with botulin toxin in women who were diagnosed with localized provoked vulvodynia. In literature covering this subject we find that the prevalence of this condition is between 10 and 15%. Especially young, sexually active women suffer from this problem and some of them are not capable of having sexual relations with their partner because of this burning pain. The most probable explanation for the physiopathological mechanism is an increase of nerve endings in the epithelium of the vestibulum, with an increase and activation of pain receptors in the vestibular mucosa. It also seems that patients with vestibulodynia have a higher tonus of the pelvic floor muscles, a greater muscle contraction in response to pain and a lower capacity of relaxation. Botulin toxin (Botox) is a neurotoxin that causes a temporary paralysis of the muscle cells. That way it can decrease the increased tension of the pelvic floor muscles Botox also inhibits the pain receptors in the vestibulum. Patients will be recruited through the gynecology consultations. Every patient with localized provoked vulvodynia that has tried previous treatments (pelvic floor muscle therapy, antidepressants, anti-epileptics, local anesthetics) will undergo Q-tip testing. If positive and there are no underlying diseases, the patient will be invited to participate in the study and after oral and written informed consent, will be included in the study population. Every 6 weeks there will be given injections with 50 units of botulin toxin, on 6 different spots in the vestibulum. 50 % of the subjects will receive physiological water instead of Botox (control population). After 3 sessions, we will assess if there is any difference in provoked pain in treated patients vs. placebos through Q-tip testing.
There have been reports in the medical literature demonstrating a link between the development of provoked vestibulodynia (PVD), a sexual pain disorder, and hormonal contraceptive (HC) use. The purpose of this pilot study is to assess the prevalence of HCs induced PVD among a HC naïve population, to evaluate which of the components of the HCs are associated with a higher risk of the development of PVD, and to evaluate which clinical and genetic factors predispose the patient to HCs induced PVD. Assessments will be made through patient questionnaires, physical examinations, and blood tests. Microarray techniques will be employed to characterize, on a global level, the gene expression profiles of women who develop PVD in comparison to those who do not develop PVD. Patients will be followed for a year. Results will be used to develop a larger clinical trial.
The main purpose of this study is to assess conception, pregnancy, childbirth, and pain experiences among women who have been diagnosed with vulvodynia. Specifically, this study aims to examine the following among women who have been diagnosed with vulvodynia: 1) rates of pregnancy/childbirth and desire for children; 2) fear of pregnancy and childbirth; 3) potential difficulties experienced while attempting to become pregnant and during pregnancy/childbirth; 4) methods used to become pregnant and deliver; 5) methods used to manage vulvodynia symptoms during pregnancy; and 6) pain outcomes associated with pregnancy. Very little research has examined pregnancy/childbirth experiences among women with vulvodynia, or the natural history of vulvodynia. As such this is a preliminary investigation that will provide descriptive information regarding many of the proposed research questions. Based on the clinical experience of the investigators, it is expected that women with vulvodynia will report lower rates of pregnancy and higher levels of fear about pregnancy and childbirth in comparison to women without such pain. It is also expected that women with vulvodynia will report more difficulties becoming pregnant as compared to women without such pain, and that women with vulvodynia will report more elective nonvaginal births in comparison to vaginal births.
This randomized trial, nicknamed the COMFORT (Cognitive therapy or Mindfulness FOR Treatment of pvd) study, will compare the effects of an 8-session group Mindfulness-based Cognitive Therapy (MBCT) to an 8-session group Cognitive Behavioural Therapy (CBT) for women with provoked vestibulodynia (PVD). Women with PVD will be randomly assigned to attend either eight sessions of group MBCT or CBT. Each session is 2.25 hours long and spaced 1 week apart. The purpose of this study is to determine whether the 8-session MBCT intervention for PVD is no worse than an 8-session CBT intervention for decreasing women's pain intensity, sexual distress, catastrophizing and hypervigilance towards pain.
This study aims to test the efficacy of a 4-session intervention (Group psychoeducational treatment) using a randomized study design. Participants will be randomized in to 'immediate treatment' or 'waitlist control'. Women in the wait-list condition will receive the 4-session IMPROVED treatment, just as women randomized to the experimental group, after the end of their wait-list period.
The purpose of this study is to investigate the possibility of an association between Localized Provoked Vulvodynia (LPV) that is both severe and primary and polymorphic markers/single nucleotide polymorphisms (SNPs) in and around the genes encoding heparanase (HSPE-1), Vanilloid Receptor VR1 (TRPV1), and Nerve Growth Factor (NGF).
Hypothesis: 1. Specific physiotherapy interventions will decrease pain, improve pelvic floor motor control, increase self efficacy, improve sexual function and decrease pain catastrophizing behaviour in women with provoked vulvar vestibulodynia. This study will look at specific physiotherapy treatment interventions to see if they decrease pain, improve pelvic floor motor control, increase self efficacy, improve sexual function and decrease pain catastophizing behaviour. Participants will fill out a questionnaire on their pain symptoms and complete standardized scales prior to starting treatment and after 4 sessions to determine change due to interventions. 2. A combination of physiotherapy, group educational sessions and group cognitive behavioural therapy will have better outcomes than physiotherapy alone. Results of physiotherapy intervention alone will be compared to results of those treated with physiotherapy, group educational sessions and group cognitive behavioural therapy at a separate treatment centre. Physiotherapy interventions and outcome measures are the same between both groups. Justification: Standard treatment is hard to identify as many approaches are taken, none with any evidence to support them. This study aims to look at specific techniques (pelvic floor coordination and relaxation exercises, education on female sexual response and pain pathophysiology education) to see if there is a benefit.
The current pilot study aims to assess the feasibility and preliminary efficacy of a novel, 12-week targeted couple intervention (CBCT) for women with vulvodynia and their partners.
The purpose of this protocol is to determine whether pain with sexual intercourse can be reduced in menopausal, breast cancer survivors and to evaluate the effectiveness of a non-hormonal therapy (Lidocaine Liquid) vs. a placebo liquid in reducing pain. The investigators hypothesize that the pain arises in the vulvar vestibule. The investigators predict that the localized use of lidocaine will be more efficacious than use of placebo liquid.
The structural/RSN study involves Structural and Resting State Neuroimaging. The purpose of Structural Neuroimaging is to use MRI technology to identify cortical and white matter morphometric differences between patients with chronic pain conditions and healthy control subjects. The purpose of the Resting State Neuroimaging study is to use functional MRI to identify possible disease related differences in various resting state networks in the brain. In addition we are looking at the effect gut microbiota on brain function in healthy and IBS participants. The overall goal is to identify structural and functional brain differences in persons with chronic pain conditions such as Irritable Bowel Syndrome (IBS, Cyclical Vomiting Syndrome(CVS) and vestibulodynia/vulvodynia. We are also looking at Inflammatory Bowel Disease(ulcerative colitis and Crohn's disease. We will be comparing differences between these conditions and matched healthy control subjects.
