Rectovaginal Fistula Management in Low-Resource Settings.

Rectovaginal fistula (RVF) is an abnormal connection between the rectum and vagina that affects women globally. In low- and middle-income countries (LMIC), RVF is most commonly due to obstetric complications such as prolonged labor or perineal tears, female genital mutilation and trauma such as sexual violence or iatrogenic surgical injuries. Women affected by this condition suffer from debilitating physical symptoms, social isolation, economic disempowerment, psychological trauma, low self-esteem, and loss of role fulfillment. Lack of accessible, high-quality, and effective healthcare is a major barrier to timely and safe obstetric care and to care for subsequent complications such as RVF. Additionally, social, cultural, financial, and systemic barriers put women at risk of acquiring fistula and contribute to delays in seeking and receiving care. Literature evaluating RVF repair in those able to access care offers limited information about management and outcomes. It is difficult to ascertain which surgical techniques are used. To reduce the burden of this often-preventable disease, appropriate investment in healthcare infrastructure to strengthen maternal care in LMICs is paramount. Furthermore, more standardized reporting of severity and treatment approach along with outcome data are critical to improving the quality of care for patients impacted by RVF.

The Impact of Local Estrogen on the Urogenital Microbiome in Genitourinary Syndrome of Menopause: A Randomized-Controlled Trial.

IMPORTANCE: The postmenopausal urinary bladder microbiome is not well defined. OBJECTIVES: The aims of this study were to characterize the effect of vaginal estrogen on the vaginal and urinary bladder microbiome in postmenopausal women and describe any clinical associations with the symptoms of genitourinary syndrome of menopause. STUDY DESIGN: This was a participant-masked, randomized controlled trial comparing the effect of a 12-week course of an estrogen-containing vaginal ring to a placebo vaginal ring. Standardized evaluations were performed at baseline and 12 weeks. Vaginal samples were obtained for pH, vaginal maturation index, and microbiome analysis. Concomitant catheterized urine samples were obtained for microbiome analysis. 16S ribosomal RNA gene sequencing was performed to characterize the resident microbial communities, with Lactobacillus relative abundance as the primary outcome variable. Genitourinary syndrome of menopause symptoms was measured using validated questionnaires (Pelvic Floor Distress Inventory-Short Form, Female Sexual Function Index, Vulvovaginal Symptoms Questionnaire). RESULTS: Of the 39 postmenopausal women randomized, baseline characteristics were similar between arms, with a mean age of 62 years and mean vaginal pH of 5.0. Using intention-to-treat analysis, there were no significant changes in vaginal or urinary Lactobacillus relative abundance. Two participants in each arm removed their ring prior to the end of the study. Eighty percent of participants experienced at least 1 bothersome genitourinary syndrome of menopause symptom. Vulvovaginal dryness and urinary frequency were most common at baseline, whereas painful intercourse and urinary urgency were most common at the final visit, none of which were statistically significant. CONCLUSIONS: Our study did not show a significant change in the bacterial composition of the vaginal or urinary bladder microbiome after either vaginal ring in this relatively asymptomatic postmenopausal population.

Characterizing persistent urinary incontinence after successful fistula closure: the Uganda experience.

BACKGROUND: Obstetric fistula is a devastating childbirth injury. Despite successful closure of the fistula, 16% to 55% of women suffer from persistent urinary incontinence after surgery. OBJECTIVE: This study assessed the type and severity of persistent incontinence after successful fistula closure and its impact on the quality of life of Ugandan women post-fistula treatment. STUDY DESIGN: This cross-sectional study enrolled women with a history of obstetric fistula repair who continued to have persistent urinary incontinence (cases, N=36) and women without incontinence (controls, N=52) after successful fistula closure. Data were collected in central and eastern Uganda between 2017 and 2019. All the participants completed a semistructured questionnaire. Cases underwent a clinical evaluation and a 2-hour pad test and completed a series of incontinence questionnaires, including two novel tools designed to assess the severity of incontinence in low-literacy populations. RESULTS: Cases were more likely to have acquired a fistula during their first delivery (63% vs 37%, P=.02), were younger when they developed a fistula (20.3±5.8 vs 24.8±7.5 years old, P=.003), and were more likely to have had >2 fistula surgeries (67% vs 2%, P≤.001). Cases reported a much higher rate of planned home birth for their index pregnancy compared to controls (44% vs 11%), though only 14% of cases and 12% of controls actually delivered at home. Cases reported higher rates of pain with intercourse (36% vs 18%, P=.05), but recent sexual activity status (intercourse within the previous six months) was not significantly different between the groups (47% vs 62%, P=.18). Among cases, 67% reported stress incontinence, 47% reported urgency incontinence, and 47% reported mixed incontinence. The cough stress test was successfully done with 92% of the cases, and of these, almost all (97%) had a positive cough stress test. More than half (53%) rated their incontinence as "very severe," which was consistent with objective findings. The 24-hour voiding diary indicated both high urinary frequency (average 14) and very frequent leakage episodes (average 20). Two-hour pad-tests indicated that 86% of cases had >4 g change in pad weight within 2 hours. Women with more severe incontinence reported a more negative impact on their quality of life. The mean score of the International Consultation on Incontinence Questionnaire-Quality of Life was 62.77±12.76 (range, 28-76, median=67), with a higher score indicating a greater impact on the quality of life. There was also a high mental health burden, with both cases and controls reporting high rates of suicidal ideation at any point since developing fistula (36% vs 31%, P=.67). CONCLUSION: Women with obstetric fistulas continue to suffer from severe persistent urinary incontinence even after successful fistula closure. Both stress and urgency incontinence are highly prevalent in this population. Worsening severity of incontinence is associated with a greater negative impact on the quality of life.

Pain Management and Its Possible Implementation Research in North Ethiopia: A before and after Study.

BACKGROUND: Though there is an effective intervention, pain after surgical intervention is undermanaged worldwide. A systematic implementation is required to increase the utilization of available evidence-based intervention to manage the inevitable pain after surgery. The aim of this research project is to develop a scalable model for managing pain after cesarean section by implementing the World Health Organization's (WHO) pain management guidelines through a combination of implementation research and quality improvement methods. METHODS: We implemented the World Health Organization (WHO) pain management guidelines using effective implementation strategies. First, we conducted a formative qualitative exploration to identify enablers and obstacles. In addition, we took base-line assessment on pain management implementation process and outcome using a checklist prepared from the guideline and an adapted American Pain Outcome assessment tool version 2010, respectively. Then, we integrated the guidelines into the existing practice by using collaborative iterative learning strategy. We analyzed the data by Statistical Packages for Social Sciences (SPSS) version 21. We compared the before and after data using chi-squared and Fischer's exact test. A change in any measurement was considered as significant at p value 0.05. RESULT: We collected data from 106 mothers before and 110 mothers after intervention implementation. We successfully integrated pain as a fifth vital sign in more than 87% (p value <0.001) of patient, and fidelity was approximately 59% (p value <0.001). In addition, we significantly improved pain outcome measures after the implementation of the intervention. Conclusion and Recommendations. A systematic approach to implement pain management guidelines was successful. We recommend the ward sustain these gains and that hospital, the region, and the nation to replicate the success.

Capacity building in female pelvic medicine and reconstructive surgery: Global Health Partnership beyond fistula care in Ethiopia.

OBJECTIVE: Obstetric fistula is a devastating childbirth injury that leaves women incontinent, stigmatized and often isolated from their families and communities. In Ethiopia, although much attention has focused on treating and preventing obstetric fistula, other more prevalent childbirth-related pelvic floor disorders, such as pelvic organ prolapse, non-fistula-related incontinence and post-fistula residual incontinence, remain largely unattended. The lack of international and local attention to addressing devastating pelvic floor disorders is concerning for women in low- and middle-income countries. The objective of this article is to highlight the need for a more comprehsive approach to pelvic floor care and to share our experience in addressing it. METHODS: Here, we share our experience launching one of the first formal training programs in Female Pelvic Medicine and Reconstructive Surgery (FPMRS) in Ethiopia. RESULTS: This fellowship program provides quality care while strengthening the health system in its local context. This program has positioned Ethiopia to be a regional leader by providing comprehensive training of surgeons and allied health professionals, building appropriate health system and research infrastructure, and developing a formal FPMRS training curriculum. CONCLUSION: We hope that sharing this experience will serve as a template for others championing comprehensive pelvic floor care for women in low- and middle-income countries.

Surgical Management of Pelvic Organ Prolapse in Ethiopian Women: What Is the Preferred Approach?

OBJECTIVES: The aim of this study was to determine the most effective approach to surgical repair of pelvic organ prolapse for Ethiopian women and to characterize this population. METHODS: This is a prospective cohort study of women presenting for prolapse repair. Demographics and assessments of prolapse were obtained preoperatively. Information surrounding the surgical encounter was collected. The same anatomic and symptomatic measures were ascertained postoperatively. Information regarding surgical complications was collected. RESULTS: Two hundred thirty-three women with stage III or IV prolapse underwent surgical prolapse repair between March 2015 and November 2017. Seventy-eight of these women participated with a median length of follow-up of 255 days. All of the sacrocolpopexy patients (n = 21) and 56 of 57 vaginal repair patients had follow-up anatomic data. Anatomic failure as defined by Pelvic Organ Prolapse-Quantification (Ba, C, or Bp > 0) occurred in 0% (0/21) of sacrocolpopexy patients and 34% (19/56) of vaginal repair patients (P = 0.005). Symptomatic failure, as defined by self-reported recurrence of vaginal bulge, occurred in 0% (0/21) of sacrocolpopexy patients and 23% (13/56) of vaginal repair patients (P = 0.015). A global assessment of improvement (worse, same, or improved) revealed that 100% (21/21) of sacrocolpopexy patients reported improvement, whereas 91% (50/55) of vaginal repair patients reported improvement, 7% (4/55) reported being the same, and 2% (1/55) reported being worse. There were 2 intraoperative complications and 3 postoperative complications. There were no cases of mesh erosion. CONCLUSIONS: Although both vaginal and abdominal routes of prolapse surgery seem to be safe, an abdominal approach with mesh augmentation may be the preferred surgical repair in Ethiopian women.

Complex Female Pelvic Pain: A Case Series From a Multidisciplinary Clinic in Urogynecology and Physiatry.

OBJECTIVE: The internal pelvic floor muscles that support the pelvic viscera lie within the external pelvic structures, which support posture and locomotion. The presence of pain in the hip, groin, leg, abdomen, and/or back in patients with pelvic pain suggests that external pelvic sites may act as pain generators that contribute to chronic pelvic pain (CPP). The aim of this study was to report musculoskeletal diagnoses resulting from including a physiatry evaluation as part of a Multidisciplinary Pelvic Pain Clinic for women with complex chronic pain. METHODS: This retrospective case series was conducted by chart review of all women attending the clinic from February 2016 through March 2018. Variable definitions were created for each demographic and clinical characteristic and used to guide a structured review of the chart. Descriptive statistical analysis was performed. RESULTS: Ninety-six percent of the 68 women (mean age, 51 years) had CPP of 6 months' duration or longer. Levator ani tenderness was present in 81% and obturator internus tenderness in 81%. Seventy-one percent of women had failed pelvic physical therapy. Musculoskeletal diagnoses included osteoarthritis, tendinopathies, enthesopathies, osteitis pubis, ischiofemoral impingement, Paget disease, and other systemic conditions. CONCLUSIONS: Musculoskeletal abnormalities were common in this highly selected cohort of complex CPP cases with external pelvic symptoms. The imaging findings and specific diagnoses allowed targeted therapy beyond generalized physical therapy for CPP. The expertise of urogynecologists and physical therapists who evaluate the internal pelvic muscles and viscera combined with the physiatrist's expertise in musculoskeletal assessment and imaging provides an expanded, collaborative approach for managing these patients.

Maternal IL-6 during pregnancy can be estimated from newborn brain connectivity and predicts future working memory in offspring.

Several lines of evidence support the link between maternal inflammation during pregnancy and increased likelihood of neurodevelopmental and psychiatric disorders in offspring. This longitudinal study seeks to advance understanding regarding implications of systemic maternal inflammation during pregnancy, indexed by plasma interleukin-6 (IL-6) concentrations, for large-scale brain system development and emerging executive function skills in offspring. We assessed maternal IL-6 during pregnancy, functional magnetic resonance imaging acquired in neonates, and working memory (an important component of executive function) at 2 years of age. Functional connectivity within and between multiple neonatal brain networks can be modeled to estimate maternal IL-6 concentrations during pregnancy. Brain regions heavily weighted in these models overlap substantially with those supporting working memory in a large meta-analysis. Maternal IL-6 also directly accounts for a portion of the variance of working memory at 2 years of age. Findings highlight the association of maternal inflammation during pregnancy with the developing functional architecture of the brain and emerging executive function.

Obstetric fistula in Niger: 6-month postoperative follow-up of 384 patients from the Danja Fistula Center.

INTRODUCTION AND HYPOTHESIS: The impoverished West African country of Niger has high rates of obstetric fistula. We report a 6-month postoperative follow-up of 384 patients from the Danja Fistula Center and assess factors associated with operative success or failure. METHODS: The medical records of 384 women who had completed a 6-month follow-up after fistula surgery were reviewed. Cases were categorized as "easy," "of intermediate complexity," or "difficult" based on a preoperative points system. Data were analyzed using simple chi-squared statistics and logistic regression. RESULTS: The patients were predominantly of Hausa ethnicity (73%), married young (average 15.9 years), had teenage first pregnancies (average first delivery 16.9 years), and experienced prolonged labor (average 2.3 days) with poor outcomes (89% stillbirth rate). The average parity was four. Patients commonly developed their fistula during their first delivery (43.5%), but over half sustained a fistula during a subsequent delivery (56.5%). Prior fistula surgery elsewhere (average 1.75 operations) was common. The overall surgical success ("closed and dry") was 54%. When the 134 primary operations were analyzed separately, the overall success rate was 80%. Increasing success was seen with decreasing surgical difficulty: 92% success for "easy" cases, 68% for "intermediate" cases, and 57% success for "difficult" cases. Success decreased with increasing numbers of previous attempts at surgical repair. CONCLUSIONS: These data provide further evidence that clinical outcomes are better when primary fistula repair is performed by expert surgeons in specialist centers with the support of trained fistula nurses.

Pelvic floor levator hiatus measurements: MRI versus ultrasound.

OBJECTIVE: The objective of this study is to compare levator hiatus measurements between pelvic magnetic resonance imaging (MRI) and pelvic ultrasound (US) imaging modalities. METHODS: We performed pelvic MRI and 3-dimensional US in 37 asymptomatic nulliparous women. For the MRI protocols, we performed axial and sagittal sequences at rest. We then obtained sagittal sequences during Kegel squeeze and Valsalva maneuvers. Blinded to the findings of the MRI, we obtained 3-dimensional pelvic US images using a perineal approach at rest, Kegel and Valsalva maneuvers. Finally, we measured the levator hiatus in both sagittal and axial planes. RESULTS: For the resting sagittal measurements, the mean levator hiatus measurement using MRI (5.0 cm; SD, 0.8) is significantly greater than that using US (4.4 cm; SD, 0.6; P < 0.05). Although the absolute mean levator measurements between the 2 modalities are significantly different, this difference is not influenced by the magnitude of the measurements as noted in Bland-Altman plots of the limits of agreement. CONCLUSIONS: We found that the MRI measurements obtained from the sagittal images were consistently greater than the corresponding US images. In contrast, there was not the same consistency of difference between MRI and US for the axial images. This suggests possible variation in acquisition planes for axial images or interpretation of landmarks for the sagittal images.

Area postrema lesions attenuate LiCl-induced c-Fos expression correlated with conditioned taste aversion learning.

Lesions of the area postrema (AP) block many of the behavioral and physiological effects of lithium chloride (LiCl) in rats, including formation of conditioned taste aversions (CTAs). Systemic administration of LiCl induces c-Fos immunoreactivity in several brain regions, including the AP, nucleus of the solitary tract (NTS), lateral parabrachial nucleus (latPBN), supraoptic nucleus (SON), paraventricular nucleus (PVN), and central nucleus of the amygdala (CeA). To determine which of these brain regions may be activated in parallel with the acquisition of LiCl-induced CTAs, we disrupted CTA learning in rats by ablating the AP and then quantified c-Fos-positive cells in these brain regions in sham- and AP-lesioned rats 1 h following LiCl or saline injection. Significant c-Fos induction after LiCl was observed in the CeA and SON of AP-lesioned rats, demonstrating activation independent of an intact AP. LiCl-induced c-Fos was significantly attenuated in the NTS, latPBN, PVN and CeA of AP-lesioned rats, suggesting that these regions are dependent on AP activation. Almost all of the lesioned rats showed some damage to the subpostremal NTS, and some rats also had damage to the dorsal motor nucleus of the vagus; this collateral damage in the brainstem may have contributed to the deficits in c-Fos response. Because c-Fos induction in several regions was correlated with magnitude of CTA acquisition, these regions are implicated in the central mediation of lithium effects during CTA learning.

Reference lines in dynamic magnetic resonance imaging of the pelvic floor.

OBJECTIVE: : To compare the variability in two commonly used reference lines in pelvic magnetic resonance imaging (MRI), the pubococcygeal line (PCL) and the sacrococcygeal to inferior pubis (SCIPP) line, with respect to their distance from pelvic floor points of interest. METHODS: : We obtained pelvic MR images of 20 asymptomatic nulliparous women who are part of an ongoing pelvic floor nerve injury postpartum study. The subjects underwent a high-resolution two-dimensional, T2-weighted sagittal pelvic MRI in the supine position using a GE Signa scanner with a body phased-array coil. We also obtained dynamic T2-weighted sagittal MR images in supine position during Kegel and Valsalva maneuvers. Using the midsagittal image, we measured the length of two reference lines: the PCL and the more cephalad SCIPP line. From each line, we then measured the perpendicular distance to the bladder neck and to the posterior margin of the anorectal angle (M-line). We compared the mean values of all measurements between the two reference lines with paired Student t tests. RESULT: : The SCIPP line (mean [SD], 11.60 [0.91] cm) is longer than the PCL (mean [SD], 10.54 [0.85] cm) at rest (P < 0.001). There is no significant change in length from resting to Kegel maneuver or from resting to Valsalva maneuver in either reference line. Only the resting to Valsalva maneuver for the M-line was significantly different between the 2 reference lines (P = 0.02). The resting to Kegel for the perpendicular distance to the bladder neck and the M-line was not significantly different between the two lines. CONCLUSIONS: : Both reference lines remain stable during pelvic floor maneuvers.

Duration of bladder catheterization after surgery for obstetric fistula.

OBJECTIVE: To compare the surgical outcome at discharge and at 6-months follow up in patients who underwent repair of obstetric fistulae with postoperative bladder catheterization for 10, 12, or 14 days. METHODS: A retrospective study of 212 obstetric fistula patients who underwent repair with postoperative bladder catheterization for 10 days (group 1), 12 days (group 2), and 14 days (group 3) at the Bahir Dar Hamlin Fistula Center in Ethiopia. Fistulas were classified according to Goh's system. RESULTS: There were 68 women (32%) in group 1, 62 women (29%) in group 2, and 82 women (39%) in group 3. There was a significant difference in the extent of urethral involvement, fistula size, and degree of vaginal scarring among the 3 groups, with the more extensively damaged patients catheterized for longer. Breakdown of repair was seen in 1.5% of patients in group 1, none in group 2, and 2% in group 3 (P=0.47). CONCLUSION: Postoperative catheterization for 10 days may be sufficient for management of less complicated obstetric vesicovaginal fistulae.
