Multifactorial contributors to the severity of chronic pelvic pain in women.

BACKGROUND: Chronic pelvic pain affects ∼15% of women, and is associated with significant societal cost and impact on women's health. Identifying factors involved in chronic pelvic pain is challenging due to its multifactorial nature and confounding between potential factors. For example, while some women with endometriosis have chronic pelvic pain, there may be comorbid conditions that are implicated in the chronic pelvic pain rather than the endometriosis itself. OBJECTIVE: We sought to explore multifactorial variables independently associated with the severity of chronic pelvic pain in women. STUDY DESIGN: We used baseline cross-sectional data from an ongoing prospective cohort, collected from patient online questionnaires, physical examination, and physician review of medical records. Participants were recruited from a tertiary referral center for endometriosis and chronic pelvic pain in Vancouver, British Columbia, Canada, from December 2013 through April 2015. Exclusion criteria included menopausal status or age >50 years. Primary outcome was self-reported severity of chronic pelvic pain in the last 3 months (0-10 numeric rating scale). Potential associated factors ranged from known pain conditions assessed by standard diagnostic criteria, validated psychological questionnaires, musculoskeletal physical exam findings, as well as pain-related, reproductive, medical/surgical, familial, demographic, and behavioral characteristics. Mann-Whitney, Kruskal-Wallis, or Spearman test were used to identify variables with an association with the primary outcome (P < .05), followed by multivariable linear regression to control for confounding and to identify independent associations with the primary outcome (P < .05). RESULTS: Overall, 656 women were included (87% consent rate), of whom 55% were diagnosed with endometriosis. The following factors were independently associated with higher severity of chronic pelvic pain: abdominal wall pain (P = .005), pelvic floor tenderness (P = .004), painful bladder syndrome (P = .019), higher score on Pain Catastrophizing Scale (P < .001), adult sexual assault (P = .043), higher body mass index (P = .023), current smoking (P = .049), and family history of chronic pain (P = .038). Severity of chronic pelvic pain was similar between women with and without endometriosis. CONCLUSION: Multifactorial variables independently associated with severity of chronic pelvic pain were identified, ranging from myofascial/musculoskeletal, urological, family history, and psycho-social factors. Continued research is required to validate these factors and to determine whether any are potentially modifiable for the management of chronic pelvic pain.

Safety and efficacy of postoperative continuous intra-peritoneal wash with lactated Ringer's for minimizing post-myomectomy pelvic adhesions: a pilot clinical trial.

OBJECTIVES: To assess efficacy and safety of post-operative intra-peritoneal wash with lactated Ringer's for 48h after myomectomy in reduction of adhesions compared to routine intra-operative irrigation. Study design A prospective, randomized trial that included 52 eligible participants who had undergone abdominal myomectomy. Participants were randomly allocated to a treatment group (n=26) which was subjected to continuous peritoneal wash for 48h via two intraperitoneal drains, and a control group (n=26). The incidence of de novo adhesions and their severity and extent were scored at a second-look laparoscopy 8-10 weeks postoperatively. Adhesions were graded using the local adhesion barrier scoring system score. Adverse effects were also assessed and reported. RESULTS: There was no statistically significant difference in duration of hospital stay or in the incidence of adverse events. A significantly higher proportion of adhesion-free patients was found in the treatment group [11/23, 47.8%] compared to the control group [4/21, 19%] (P<0.01). The mean number of pelvic sites covered by adhesions was significantly lower in the treatment group than in the control group (2.2±0.3 versus 4.6±0.8, P<0.05). The total adhesion score was significantly lower in the treatment group than in the control group (2.1±0.5 versus 4.8±1.4, P<0.05) and the adhesion score was significantly lower at most of the individual anatomical sites. CONCLUSIONS: Application of postoperative intraperitoneal wash with lactated Ringer's solution for 48h may have reasonable safety and efficacy in minimizing postoperative pelvic de novo adhesions following abdominal myomectomy.

Early amniotomy after vaginal misoprostol for induction of labor: a randomized clinical trial.

OBJECTIVES: To test the effectiveness and safety of early amniotomy after vaginal misoprostol for the induction of labor. STUDY DESIGN: A randomized clinical trial that included 320 women with medical or obstetric indication for labor induction. They were randomly assigned into two equal groups, amniotomy group and control group. Each participant received vaginal misoprostol 50 µg every 6 h for induction of labor. In amniotomy group, amniotomy was done in the early active phase of labor while in the control group, the membranes were left to rupture spontaneously or as judged by the senior resident in the duty. RESULTS: More subjects in the amniotomy group achieved vaginal delivery within 24 h than in the control group [117 (73.13 %) vs. 105 (65.63 %)]. Subjects in the amniotomy group reported shorter induction to delivery interval (09.72 ± 4.61 h vs. 13.61 ± 5.61, P = .002), and better neonatal outcome compared to the control group. There were no statistically significant differences between both group with regard to number of doses of misoprostol, need for oxytocin, Cesarean Section indication and maternal side effects. CONCLUSION: Early amniotomy after vaginal misoprostol for labor induction is associated with higher successful vaginal delivery rate, shorter labor duration and better neonatal outcome.

Reproductive outcome after letrozole versus laparoscopic ovarian drilling for clomiphene-resistant polycystic ovary syndrome.

OBJECTIVE: To compare the clinical outcomes of letrozole and laparoscopic ovarian drilling (LOD) in patients with clomiphene-citrate-resistant polycystic ovary syndrome (PCOS). METHODS: In the present prospective randomized trial, 140 women with clomiphene-citrate-resistant PCOS were randomly allocated to receive 5mg letrozole from day 3 to day 7 of menses for 6 consecutive cycles, or to undergo LOD. When a leading follicle of at least 18 mm was present, ovulation was triggered with human chorionic gonadotropin (hCG). The 6-month rates of ovulation, pregnancy, abortion, and live births were evaluated. RESULTS: The groups were similar with regard to baseline clinical characteristics and hormonal profiles. The ovulation rate was significantly higher in the letrozole group than in the LOD group (59.0% versus 47.5%). On the days of the hCG injection, women in the letrozole group had a significantly thicker endometrium than those in the LOD group (P<0.0001). Women receiving letrozole had a higher pregnancy rate (35.7% versus 28.6%) and a lower rate of spontaneous abortion (8.0% versus 20.0%, respectively), but these differences were not statistically significant. CONCLUSION: Letrozole seems to be a suitable second-line ovulation-inducing alternative to LOD in women with PCOS who do not conceive with clomiphene citrate.

Intravaginal administration of isosorbide mononitrate and misoprostol for cervical ripening and induction of labour: a randomized controlled trial.

BACKGROUND: Labor induction in the presence of unfavorable cervix is a common indication for the use of prostaglandins. However, in the last years, there has been a considerable interest in the use of nitrous oxide donors for cervical ripening and labor induction. OBJECTIVE: To evaluate the efficacy and safety of intravaginal administration of NOD isosorbide mononitrate (IMN) plus misoprostol versus misoprostol alone for cervical ripening and induction of labor. SETTING: Department of Obstetrics and Gynecology, Woman's Health Center, Assiut University. METHODS: Two hundred and ninety women scheduled for labor induction were recruited and assigned randomly to IMN or placebo followed by misoprostol 50 µg. The efficacy of the medication was evaluated by predetermined outcome variables for cervical ripening and induction of labor and delivery. RESULTS: The two groups were comparable with respect to age, parity, gestational age, indication for induction, and Bishop's score. Women receiving IMN plus misoprostol showed significant changes in the Bishop score 6 h after administration as compared to misoprostol plus placebo (8.57 ± 1.46 vs. 7.6 ± 1.39 h, P = 0.001), significantly shorter intervals from the beginning of the induction to the beginning of the active phase of labor (10.97 ± 2.87 vs. 13.91 ± 2.16 h, P = 0.0004) and from the beginning of induction to the time of delivery (19.56 ± 3.96 vs. 23 ± 2.62 P ≤ 0.001). No significant differences in the incidence of uterine hypersystole, tachysystole and hyperstimulation. Regarding headache, much more women suffer headache in the IMN group (51) with significant difference to placebo group (11). CONCLUSIONS: Using a combination of IMN and misoprostol is more efficient than misoprostol alone in terms of fast cervical ripening and shortening of induction-labour interval.

Sublingual versus vaginal misoprostol for induction of labor at term: a randomized prospective placebo-controlled study.

AIMS: To assess the effectiveness and safety of sublingual misoprostol (50 microg), compared with the same dose administered vaginally every 6 h for cervical ripening and labor induction in women with a viable fetus in the third trimester of pregnancy. METHODS: This double-blind randomized prospective placebo-controlled trial included 480 women with medical or obstetric indications for labor induction and undilated, uneffaced cervices. The patients were assigned randomly to receive 50 microg of sublingual or 50 microg of vaginal misoprostol every 6 h for 24 h. Maternal and neonatal outcome were analyzed. RESULTS: A total of 169 (70.4%) patients delivered vaginally in the sublingual group compared to 160 (66.7%) in the vaginal group. The main indications for cesarean section in both groups were fetal distress (33/71 [46.4%] vs 38/80 [47.5%]), followed by failure of labor progress. Thirty three (13.8%) patients in the sublingual group had meconium staining of the amniotic fluid compared to 39 (16.3%) in the vaginal group. There was no difference between the groups regarding the induction-to-delivery interval, duration of labor, neonatal outcome or maternal side-effects. CONCLUSION: Sublingual misoprostol is as effective as vaginal misoprostol for induction of labor at term. Moreover, the sublingual route is associated with a significantly higher patient satisfaction rate than vaginal misoprostol.
