Vulvodynia: A practical guide in treatment strategies

Vulvodynia is a debilitating condition characterized by chronic vulvar pain, with a detrimental impact on the patient's overall quality of life. Its etiology is multifactorial, but still in the process of being clearly outlined. Vulvodynia is not a single entity. It is a heterogeneous condition characterized by multiple triggers, making it challenging to define a reference standard for its treatment. In this manuscript we selected all articles including the following key criteria: "vulvodynia". The primary outcomes observed included the resolution of chronic pelvic pain, dyspareunia and sexual satisfaction, psychological well-being, and overall quality of life. Most pharmacologic treatments require further evidence to be recommended. On the other hand, non-pharmacologic approaches such as psychotherapy, physical therapy, and surgery have received stronger support. This review summarizes pros and cons of adopting available treatments. Multimodal approaches should be introduced to improve patient outcomes. Further investigations are warranted to improve patients' quality of life.

Treatment of Vulvodynia: Pharmacological and Non-Pharmacological Approaches

Vulvodynia is a common, recurrent, vulvar pain condition with debilitating consequences for affected women's health and quality of life. The heterogeneity of women suffering from vulvodynia as well as its uncertain and likely multifactorial etiology pose a significant challenge to identifying any kind of "gold standard" treatment. Thus, treatment providers must be well versed in the various options and the evidence for each. In this review, we begin with pharmacological treatments, followed by non-pharmacological treatments, surgery, and finally multimodal treatments. For each approach, we briefly discuss the method, mechanism of action, and empirical support for the treatment. In sum, pharmacological treatments that may be beneficial but require further research include antinociceptive agents (lidocaine, capsaicin), anti-inflammatory agents (corticosteroids, interferon), neuromodulating medications (anticonvulsants and antidepressants), hormonal agents, and muscle relaxants (e.g., botulinum toxin). There is strong evidence to support and recommend non-pharmacological interventions including psychological therapy, pelvic floor physical therapy, as well as surgery (i.e., vestibulectomy for provoked vestibulodynia) for the treatment of vulvodynia. We conclude this review with a discussion of issues that may have hindered progress of treatment efficacy and effectiveness, and recommendations for moving the field forward.

Effectiveness of two different acupuncture strategies in patients with vulvodynia: Study protocol for a pilot pragmatic controlled trial

BACKGROUND

Vulvodynia, or vulvar pain, is a common condition in women; however, there are few evidence-based clinical trials evaluating nonpharmacological therapies for this condition. Acupuncture is one complementary and integrative medicine therapy used by some patients with vulvodynia. This study evaluates two different acupuncture strategies for the treatment of vulvodynia and aims to evaluate whether either of the acupuncture protocols reduces vulvar pain, pain duration or pain with intercourse. The study also examines how long the effect of acupuncture lasts in women with vulvodynia.

METHODS/DESIGN

The study is designed as a randomized controlled trial, focused on two acupuncture protocols. Fifty-one patients who have had vulvodynia for more than 3 months will be recruited. Among them, 34 patients will be randomized into Groups 1a and 1b; those who are unwilling to receive acupuncture will be recruited into the standard care group (Group 2). Patients in Group 1a will have acupuncture focused on the points in the pudendal nerve distribution area, while patients in Group 1b will receive acupuncture focused on traditional (distal) meridian points. Patients in Group 2 will receive routine conventional treatments, such as using pain medications, local injections and physical therapies or other nonsurgical procedures. Acupuncture will last 45 min per session, once or twice a week for 6 weeks. The primary outcome measurement will be objective pain intensity, using the cotton swab test. The secondary outcome measurement will be subjective patient self-reported pain intensity, which will be conducted before cotton swab test. Pain intensities will be measured by an 11-point Numeric Pain Rating Scale. Pain duration and pain score during intercourse are recorded. Local muscle tension, tenderness and trigger points (Ashi points) are also recorded. All measurements will be recorded at baseline (before the treatment), at the end of each week during treatment and at the end of the 6 weeks. Follow-up will be done 6 weeks following the last treatment.

DISCUSSION

Results of this trial will provide preliminary data on whether acupuncture provides better outcomes than nonacupuncture treatments, i.e., standard care, and whether acupuncture focused on the points in pudendal nerve distribution, near the pain area, has better results than traditional acupuncture focused on distal meridian points for vulvodynia.
