Postpartum dyspareunia: clinical evaluation, causes, and treatment outcomes.

BACKGROUND: Dyspareunia affects approximately half of postpartum women and is attributed to multiple factors. Despite its high prevalence and resultant negative effects, data are lacking regarding the causes and different pain components, the usefulness of recommended treatments, and the prognosis. AIM: To evaluate causes of postpartum dyspareunia, targeted treatment modalities, and their effectiveness. METHODS: A retrospective observational study was conducted of women diagnosed with postpartum dyspareunia between September 2008 and January 2017 at a single designated vulvovaginal disorder clinic. The inclusion criterion was complaint of painful intercourse commencing postdelivery. The cohort was divided into 4 groups based on the causes of dyspareunia: muscle hypertonicity, scar tenderness, vestibular tenderness, and atrophy. OUTCOMES: The following were assessed for each group: patient background demographics, clinical and obstetric data, physical findings, recommended therapy, adherence to the suggested treatment, level of improvement at follow-up visits, and length of time until maximal improvement. RESULTS: A hundred women met the inclusion criterion; the majority (n = 60) presented with >1 causative factor. The most common finding was vestibular tenderness (n = 78, 78%), which was significantly associated with atrophy (adjusted odds ratio [aOR], 15.08; 95% CI, 2.45-93.35), contraceptive usage (aOR, 4.76; 95% CI, 1.07-21.39), and primiparity (aOR, 4.89; 95% CI, 1.01-23.88). Episiotomy was the only risk factor for scar tenderness (aOR, 5.43; 95% CI, 1.20-24.53), while the existence of a spontaneous perineal tear was not. No specific correlation was found with pelvic floor muscle hypertonicity. Targeted treatment resulted in significant improvement in most patients. CLINICAL IMPLICATIONS: A targeted diagnostic and treatment approach for postpartum dyspareunia is effective and can be beneficial for caregivers treating postpartum women. STRENGTHS AND LIMITATIONS: A uniform and consistent protocol for patient selection and management is a major strength, which magnifies the clinical implication of our findings. The retrospective nature of the study is the primary limitation. CONCLUSION: Postpartum dyspareunia is a common problem; however, many women refrain from discussing it with their providers. Therefore, it is important to assess this condition with all women during the postpartum visit as targeted diagnosis and treatment can significantly improve outcomes.

The Vaginal Microbiome: II. Vaginal Dysbiotic Conditions.

OBJECTIVE: This series of articles, titled The Vaginal Microbiome (VMB), written on behalf of the International Society for the Study of Vulvovaginal Disease, aims to summarize the recent findings and understanding of the vaginal bacterial microbiota, mainly regarding areas relevant to clinicians specializing in vulvovaginal disorders. MATERIALS AND METHODS: A search of PubMed database was performed, using the search terms "vaginal microbiome" with "dysbiosis," "bacterial vaginosis," "cytolytic vaginosis," "desquamative inflammatory vaginitis," and "aerobic vaginitis." Full article texts were reviewed. Reference lists were screened for additional articles. RESULTS: The second article in this series focuses on vaginal dysbiotic conditions. Dysbiosis is a term describing imbalances in bacterial communities. Given that lactobacillus-dominated microbiota are thought to be the most optimal, vaginal dysbiosis is usually considered as lactobacilli-depleted VMB. Bacterial vaginosis (BV), the most common vaginal dysbiotic condition, is a polymicrobial disorder, considered the leading cause for vaginal discharge in women worldwide. In addition, we review the VMB in other vaginal conditions associated with lactobacilli depletion: desquamative inflammatory vaginitis and aerobic vaginitis. We also discuss the controversial diagnosis of cytolytic vaginosis, related with lactobacilli overgrowth. CONCLUSIONS: Bacterial vaginosis displays complex microbiology. The heterogeneity and diversity within the genus Gardnerella may impact the progression of BV. Bacterial biofilms may contribute to the etiology and persistence of BV, and various bacteria may affect its clinical presentation and pathogenicity. Lack of lactobacilli is not always accompanied by an overgrowth of anaerobes.

The Vaginal Microbiome: I. Research Development, Lexicon, Defining "Normal" and the Dynamics Throughout Women's Lives.

OBJECTIVE: This series of articles, titled The Vaginal Microbiome, written on behalf of the International Society for the Study of Vulvovaginal Disease, aims to summarize the current findings and understanding of the vaginal bacterial microbiota, mainly regarding areas relevant to clinicians specializing in vulvovaginal disorders. MATERIALS AND METHODS: A database search of PubMed was performed, using the search terms "vaginal microbiome" (VMB) with "research," "normal," "neonate," "puberty," "adolescent," "menopause," and "ethnicities," as well as "human microbiome project." Full article texts were reviewed. Reference lists were screened for additional articles. RESULTS: In the last 2 decades, many studies applying molecular techniques were performed, intending to characterize the vaginal microbiota. These studies advanced our understanding of how vaginal health is defined. The first article in this series focuses on the advancement of VMB research, technical definitions, the definition of "normal" VMB, and the dynamics of VMB throughout women's lives. CONCLUSIONS: Understanding how microorganisms inhabiting the vagina interact with each other and with the host is important for a more complete understanding of vaginal health. The clinical application of microbial community sequencing is in its beginning, and its interpretation regarding practical clinical aspects is yet to be determined.

The Vaginal Microbiome: IV. The Role of Vaginal Microbiome in Reproduction and in Gynecologic Cancers.

OBJECTIVE: This series of articles, titled The Vaginal Microbiome (VMB), written on behalf of the International Society for the Study of Vulvovaginal Disease, aims to summarize the recent findings and understanding of the vaginal bacterial microbiota, mainly regarding areas relevant to clinicians specializing in vulvovaginal disorders. MATERIALS AND METHODS: A search of PubMed database was performed, using the search terms "vaginal microbiome" with "reproduction," "infertility," "fertility," "miscarriages," "pregnancy" "cervical cancer," "endometrial cancer," and "ovarian cancer." Full article texts were reviewed. Reference lists were screened for additional articles. RESULTS: The fourth article of this series focuses on 2 distinct areas: the role of VMB in various aspects of human reproduction and, in sharp contrast, the association between the VMB and gynecologic malignancies. Several of the negative pregnancy outcomes have been associated with an altered VMB. Dysbiosis is remarkably linked with poor pregnancy outcomes from preconception to delivery. The associations between the microbiome and gynecologic cancers are described. CONCLUSIONS: The development of the microbiome research, enabled by molecular-based techniques, has dramatically increased the detection of microorganisms and the understanding of bacterial communities that are relevant to maternal-fetal medicine in health and disease, as well as in gynecological malignancies. Proving causation in cancer is difficult because of the complex interactive nature of potential causative factors. Certain elements of the microbiota have been shown to provoke inflammatory reactions, whereas others produce anti-inflammatory reactions; this balance might be impaired with a change in microbial variety.

The Vaginal Microbiome: V. Therapeutic Modalities of Vaginal Microbiome Engineering and Research Challenges.

OBJECTIVE: This series of articles, titled The Vaginal Microbiome (VMB), written on behalf of the International Society for the Study of Vulvovaginal Disease, aims to summarize the recent findings and understanding of the vaginal bacterial microbiota, mainly regarding areas relevant to clinicians specializing in vulvovaginal disorders. MATERIALS AND METHODS: A search of PubMed database was performed, using the search terms "vaginal microbiome" with "treatment," "diagnosis," and "research." Full article texts were reviewed. Reference lists were screened for additional articles. RESULTS: The currently available approaches for treating vaginitis or attempting to modulate the VMB are often insufficient. It has traditionally relied on the use of antibiotics, antiseptics, and antifungals. The fifth and last article of this series discusses the new and/or alternative therapeutic modalities. It addresses the role of probiotics, prebiotics and symbiotics, activated charcoal, biofilm disrupting agents, acidifying agents, phage therapy, and the concept of vaginal microbiome transplant. The challenges facing the research of VMB, including the clinical impact of microbiome manipulation, classification, and new diagnostic approaches are discussed. CONCLUSIONS: Microbiome research has grown dramatically in recent years, motivated by innovations in technology and decrease in analysis costs. This research has yielded huge insight into the nature of microbial communities, their interactions, and effects with their hosts and other microbes. Further understanding of the bacterial, fungal, phage, and viral microbiomes in combination with host genetics, immunologic status, and environmental factors is needed to better understand and provide personalized medical diagnostics and interventions to improve women's health.

The Vaginal Microbiome: III. The Vaginal Microbiome in Various Urogenital Disorders.

OBJECTIVE: This series of articles, titled The Vaginal Microbiome (VMB), written on behalf of the International Society for the Study of Vulvovaginal Disease, aims to summarize the recent findings and understanding of the vaginal bacterial microbiota, mainly regarding areas relevant to clinicians specializing in vulvovaginal disorders. MATERIALS AND METHODS: A search of PubMed database was performed, using the search terms "vaginal microbiome" with "Candida," "vaginitis," "urinary microbiome," "recurrent urinary tract infections," "sexually transmitted infections," "human immunodeficiency virus," "human papillomavirus," "nonspecific vaginitis," "vulvodynia," and "vulvovaginal symptoms." Full article texts were reviewed. Reference lists were screened for additional articles. The third article in this series describes VMB in various urogenital disorders. RESULTS: Variable patterns of the VMB are found in patients with vulvovaginal candidiasis, challenging the idea of a protective role of lactobacilli. Highly similar strains of health-associated commensal bacteria are shared in both the bladder and vagina of the same individual and may provide protection against urinary tract infections. Dysbiotic VMB increases the risk of urinary tract infection. Loss of vaginal lactic acid-producing bacteria combined with elevated pH, increase the risk for sexually transmitted infections, although the exact protective mechanisms of the VMB against sexually transmitted infections are still unknown. CONCLUSIONS: The VMB may constitute a biological barrier to pathogenic microorganisms. When the predominance of lactobacilli community is disrupted, there is an increased risk for the acquisition of various vaginal pathogents. Longitudinal studies are needed to describe the association between the host, bacterial, and fungal components of the VMB.

Prevalence and Characteristics of Postpartum Vulvovaginal Atrophy and Lack of Association With Postpartum Dyspareunia.

OBJECTIVE: Breastfeeding-related hypoestrogenic state has been reported as a possible risk factor for postpartum dyspareunia. This study aimed to evaluate the prevalence and characteristics of postpartum vulvovaginal atrophy according to 3 different diagnostic methods and to estimate its association with postpartum dyspareunia and daily vulvovaginal symptoms. METHODS: This is a prospective cohort study of puerperal women attending a routine postpartum checkup. Participants completed a questionnaire and underwent a gynecological examination. Atrophy was diagnosed separately according to gynecologist impression, vaginal pH measurement (≥5.1), and cytologic vaginal maturation index. Patients were followed up with a telephone survey 2-3 months later, inquiring about symptoms possibly associated with atrophy. RESULTS: Of 117 participants, vaginal atrophy was diagnosed in 48% by gynecological examination, 62% by a pH level of 5.1 or greater, and 40.2% had cytological atrophy. Of the 35.9% of women who had resumed sexual intercourse (42/117), 69% reported dyspareunia. No significant association was found between dyspareunia and atrophy parameters. There was no difference in the rates of dyspareunia among women who were exclusively breastfeeding (21/27 = 78%), partially breastfeeding (4/7 = 57%), or not breastfeeding (4/8, 50%). Atrophy was more common in breastfeeding women according to the 3 criteria (gynecological examination: 57.6% vs 16.7%, p = .006; pH: 70% vs 22%, p < .001; vaginal maturation index: 51.1% vs 0%, p < .001). Of the 117 participants, 47% reported daily vulvovaginal symptoms. Those with daily symptoms reported more dyspareunia as compared with those without daily symptoms (85% vs 52%, p = .025). CONCLUSIONS: A high prevalence of atrophy was observed in puerperal women in association with breastfeeding. There was no significant association between atrophy and dyspareunia or daily vulvovaginal symptoms.

Low-Level Laser Therapy for the Treatment of Provoked Vestibulodynia-A Randomized, Placebo-Controlled Pilot Trial.

BACKGROUND: Low-level laser therapy (LLLT) is an emerging medical technology in which non-thermal laser irradiation is applied to treat pain. Because LLLT has been found effective in treating various pain syndromes without known side effects, we conducted a study evaluating the effect of LLLT on provoked vestibulodynia (PVD), a complex sexual pain disorder characterized by pain confined to the vulvar vestibule in response to contact or pressure. AIM: To investigate the effectiveness of LLLT for PVD in a randomized, placebo-controlled, double-blinded trial. METHODS: Patients with PVD were randomly assigned to receive treatment with LLLT or sham treatment. Patients were treated twice weekly for 6 weeks, for a total of 12 LLLT or placebo sessions. Patients who showed improvement after LLLT were followed for 1 year by clinical pain report and Q-tip examination. OUTCOMES: Change in pain scores obtained in response to the Q-tip test, clinical pain report, visual analog scale score, pain with tampon insertion, daily pain intensity, intercourse pain intensity, frequency of intercourse, and a battery of quality-of-life measures. RESULTS: Thirty-four patients with PVD participated, 18 received LLLT and 16 received placebo. In the clinical pain report at study completion, 14 of 18 patients (78%) receiving LLLT reported improvement compared with 7 of 16 (44%) in the placebo group (P = .042). This effect was not apparent in other outcome measurements. None of the patients reported side effects during the study. At 1-year follow-up, eight patients (57%) reported lasting improvement. CLINICAL IMPLICATIONS: Larger studies with various treatment protocols are needed to define which patients can benefit from LLLT therapy. STRENGTHS AND LIMITATIONS: Strengths include a placebo-controlled, double-blinded design, measurement of a large number of multidimensional end points, and a follow-up period of 1 year. Limitations include the small number of patients recruited, no improvement in measurable parameters, a high improvement rate in the placebo group, the absence of use of validated questionnaires, and the lack of evaluation of psychological and interpersonal factors that might have influenced the results. CONCLUSIONS: Given the results of this pilot study, LLLT cannot currently be recommended as a treatment for PVD. Further studies with a larger population, various treatment protocols, and evaluation of LLLT in different subgroups of PVD are needed to define which patients can benefit from this therapy.

Standards for Clinical Trials in Male and Female Sexual Dysfunction: IV. Unique Aspects of Clinical Trials in Female Sexual Dysfunction.

The focus of this article, the fourth in the series, Standards for Clinical Trials in Male and Female Sexual Dysfunction, is on aspects of clinical trial design and measurement that are specific to clinical trials for treatments of female sexual dysfunction. Challenges in this area include the limited extent of treatment development and clinical trial research across the spectrum of female sexual dysfunctions, changing regulatory considerations, changing diagnostic criteria for female sexual dysfunction, and the need to articulate assessment procedures to these changes. Discussion focuses on approaches to addressing these challenges in clinical trials in female sexual dysfunction.

Standards for Clinical Trials in Male and Female Sexual Dysfunction: III. Unique Aspects of Clinical Trials in Male Sexual Dysfunction.

This series of articles, Standards for Clinical Trials in Male and Female Sexual Dysfunction, began with the discussion of a common expected standard for clinical trial design in male and female sexual dysfunction, a common rationale for the design of phase I to IV clinical trials, and common considerations for the selection of study population and study duration in male and female sexual dysfunction. The second article in this series discussed fundamental principles in development, validation, and selection of patient- (and partner-) reported outcome assessment. The third and present article in this series discusses selected aspects of sexual dysfunction that are that are unique to male sexual dysfunctions and relevant to the conduct of clinical trials of candidate treatments for men.
