Obstetrics and Gynecology Dec 2023To compare the labor curve between individuals with induced labor and those undergoing spontaneous labor. (Comparative Study)
Comparative Study
OBJECTIVE
To compare the labor curve between individuals with induced labor and those undergoing spontaneous labor.
METHODS
This was a secondary analysis of the Consortium on Safe Labor database, including nulliparous and multiparous individuals with singleton vertex pregnancy who delivered vaginally after spontaneous labor or induction of labor at term. Labor that resulted in uterine rupture and neonates with a 5-minute Apgar scores less than 7, birth injury, or neonatal intensive care unit admission was excluded. We modeled the course of cervical dilation using repeated-measures analysis with a polynomial function. We compared traverse time , defined as the elapsed time between two given dilation measures, between induced and spontaneous labor using interval-censored regression.
RESULTS
Of 46,835 nulliparous individuals, 18,576 and 28,259 underwent induced and spontaneous labor, respectively. Of 77,503 multiparous individuals, 29,684 and 47,819 underwent induced and spontaneous labor, respectively. The start of the active phase on the labor curve was 6 cm in induced labor, regardless of parity. In nulliparous individuals, induced labor compared with spontaneous labor had a significantly shorter traverse time from 6 to 10 cm (median 1.8 hours [5th-95th percentile 0.4-8.6 hours] vs 2.3 hours [5th-95th percentile 0.6-9.4 hours]; P <.01). In multiparous individuals, induced labor compared with spontaneous labor had a significantly shorter traverse time from 6 to 10 cm (median 0.9 hours [5th-95th percentile 0.1-6.0 hours] vs 1.4 hours [5th-95th percentile 0.3-7.9 hours]; P <.01).
CONCLUSION
Similar to spontaneous labor, the start of the active phase of induced labor was at 6 cm of dilation. Comparatively, induced labor had a shorter active phase than spontaneous labor. These findings suggest that the current criteria for active phase arrest provided by the American College of Obstetricians and Gynecologists do not need to be lengthened for individuals in induced labor.

BACKGROUND
Müllerian agenesis, known as Mayer-Rokitansky-Küster-Hauser syndrome, is characterized by the absence of the uterus, cervix, and two thirds of the proximal vagina. To allow sexual intercourse, dilatator-based conservative approaches and Vecchietti vaginoplasty generate progressive traction on the vaginal stump until adequate vaginal size is achieved. Other approaches create the neovagina using mucous/cutaneous, peritoneal, or ileal/sigmoid grafts or cutaneous flaps from the genitalia to fulfill a newly developed space between the bladder and rectum. The drawback of the first approach is the long time required, whereas stenosis, dehiscence, poor esthetic results, or absence of vaginal sensitivity limit the latter.
OBJECTIVE
To present a new surgical technique on the basis of an internal thigh fasciocutaneous flap for generating a compliant and sensitive neovagina with preservation of the external genitalia.
DESIGN
Video demonstration of the surgical steps.
PATIENT(S)
An 18-year-old woman with Müllerian agenesis confirmed at ultrasound and magnetic resonance imaging. The residual vagina was 3 cm long and 1.5 cm wide. After counseling by a gynecologist and plastic surgeon, in which all available techniques with pros and cons were exposed, the patient opted for the new technique. The long time required by conservative approaches and the desire to preserve the external genitalia with the chance to have a sensitive vagina guided the choice.
INTERVENTION(S)
The cul-de-sac of the vaginal stump was incised transversally. A 4-cm-wide and 9-cm-long canal bounded anteriorly by the bladder, posteriorly by the rectum, and superiorly by the peritoneum of Douglas was developed by blunt dissection. Fasciocutaneous flaps of 12 per 5 cm on the anteromedial aspect of the thighs were developed, identifying the vascular-from the pudendal artery-and nervous pedicles. A tunnel between the flap pedicles and neovagina introitus was created between fascia and subcutaneous tissue, detaching the vulvar structures from the ischiopubic ramus. Flaps were tunneled up to the neovagina introitus and sutured together by interrupted suture to form a tube with outside skin. The flaps were transposed into the canal everting the tube to obtain the skin lining the internal neovagina. The inferior margins of the flaps were sutured to the vaginal stump mucosa. No internal stitches were placed. Antibiotic prophylaxis was used during surgery. The entire procedure lasted 6 hours. During the postoperative period, no special positioning or ambulation restrictions were used.
MAIN OUTCOME MEASURE(S)
Compliance and sensitivity of the neovagina, esthetic result, and perioperative and long-term complications.
RESULT(S)
The postoperative course was uneventful, with early mobilization. The length of hospital stay was 16 days to allow proper vaginal dilator use; initial daily followed by intermittent use was planned. At a 2-year follow-up, the neovagina was sensitive and patent, allowing sexual intercourse. No complications were reported, and the patient was satisfied with the functional and esthetic result.
CONCLUSION(S)
The new surgical technique was feasible and effective, preserving the external genitalia and avoiding graft healing and bowel secretion drawbacks without an intra-abdominal surgical step and related risks. However, more cases-2 cases performed to date with similar results-and long-term follow-up are needed to confirm the efficacy. In this regard, the regular use of vaginal dilators and forecast adherence between flaps and the connective tissue of the bladder and rectum are expected to prevent neovagina prolapse without any anchoring to the pelvic structures.

Ogilvie's syndrome is a colonic pseudo-obstruction that results in colonic dilation without a mechanical obstruction. We discuss a 33-year-old, 36-week pregnant, G1P0L0A0 female who presented with severe pre-eclampsia. Less than 24 hours after induction by vaginal delivery, she developed significant abdominal pain and distention. On a CT scan of the abdomen and pelvis, she was diagnosed with Ogilvie's syndrome due to a finding of large bowel dilation with an abrupt transition point at the splenic flexure without a noted mass. She was initially treated conservatively with nasogastric tube decompression and IV fluid resuscitation. When these conservative measures failed, neostigmine was administered with transient improvement in symptoms. Despite the appropriate administration of neostigmine and initial relief of symptoms with stool output, the patient ultimately required surgical intervention with the creation of a transverse loop colostomy. The development of Ogilvie's syndrome in the postpartum period is a very rare finding, particularly after a vaginal delivery.

BACKGROUND
Poor outcomes from operative vaginal birth have been associated with failure to recognize malposition, breakdown in interdisciplinary communication, and deviation from accepted guidelines. We recently implemented a safety bundle including routine intrapartum ultrasound and a structured time-out and procedural checklist aiming to reduce maternal and perinatal morbidity from operative vaginal birth.
OBJECTIVE
This study aimed to compare births where intrapartum ultrasound was used and those where it was not used during a safety bundle implementation period at Monash Health.
STUDY DESIGN
We performed a retrospective cohort study at Monash Health during the transitional phase of implementing an operative vaginal birth safety bundle. We studied all women with operative vaginal birth and fully dilated cesarean delivery with a singleton cephalic term fetus. We compared births for which intrapartum ultrasound was used and those for which it was not. The primary outcome was neonates delivered in an unexpected position. Neonatal and maternal morbidity were also assessed, including a neonatal composite of Apgar score <7 at 5 minutes, cord lactate >8 mmol/L, need for resuscitation, significant birth trauma, or neonatal intensive care unit admission. To control for confounding by indication, we estimated propensity scores for the probability of using intrapartum ultrasound for each case based on maternal and labor characteristics, and adjusted the effect estimates for the propensity scores using multivariable logistic regression models.
RESULTS
From August 2022 to July 2023, there were 1205 operative vaginal births or fully dilated cesarean deliveries at Monash Health, including 743 (61.7%) forceps, 346 (28.7%) vacuum, and 116 (9.6%) fully dilated cesarean deliveries. Over this time, we observed increased uptake of intrapartum ultrasound from 26% in August 2022 to 60% (P<.001) in July 2023, of the time-out from 21% to 58% (P<.001), and the checklist from 33% to 80% (P<.001) of operative second-stage births. Among the births where intrapartum ultrasound was used (n=509), compared with those where it was not (n=696), there were significantly more forceps births (67% vs 58%; adjusted odds ratio, 1.35; 95% confidence interval, 1.05-1.74; P=.021) and a reduction in vacuum births (24% vs 32%; adjusted odds ratio, 0.77; 95% confidence interval, 0.58-1.01; P=.059). There were no significant differences in fully dilated cesarean delivery or maternal morbidity. Intrapartum ultrasound use was associated with significantly fewer infants being delivered in an unexpected position (0.2% vs 2.2%; adjusted odds ratio, 0.08; 95% confidence interval, 0.00-0.44; P=.019) and a significant reduction in composite neonatal morbidity (22% vs 25%; adjusted odds ratio, 0.73; 95% confidence interval, 0.54-0.97; P=.031).
CONCLUSION
During the implementation of a safety bundle, the use of ultrasound before operative vaginal birth was associated with fewer infants delivered in an unexpected position and reduced neonatal morbidity.

BMC Pregnancy and Childbirth Sep 2023The study aims were to analyze pregnancy outcomes after the use of emergency cerclage in patients with different BMIs.
BACKGROUND
The study aims were to analyze pregnancy outcomes after the use of emergency cerclage in patients with different BMIs.
METHODS
A total of 76 singleton pregnant patients who underwent emergency cerclage at a tertiary comprehensive hospital in China between Jan 2017 and Dec 2021 were retrospectively divided into an obesity group of 37 patients with BMIs ≥ 28 kg/m and a non-obesity group of 39 patients with BMIs < 28 kg/m. The medical records of patients were reviewed and all relevant clinical data were further collected into an itemized data spreadsheet for various analyses.
RESULTS
Emergent cerclage, along with amnioreduction if needed, could be safely performed on both obese and non-obese pregnant women with a dilated external cervix (> 1 cm), which effectively prolonged the gestational week up to ≥ 25 weeks. Obese gravidae had shorter suture-to-delivery intervals and mean pregnancy lengths but more spontaneous preterm births before 37 weeks, and a lower live birth rate (P < 0.05). Logistic regression analysis revealed that BMI, how many times cerclages have been performed during pregnancy (frequency of cerclage) and bacterial vaginosis, aerobic vaginitis and vulvovaginal candidiasis (vaginal microecology) were significantly correlated with fetal loss (P < 0.05), while rank correlation analysis established a negative correlation between BMI values and the suture-to-delivery interval (P = 0.031).
CONCLUSIONS
Pregnant cervical insufficiency patients with BMIs > 28 kg/m may ill-serve the gestational outcomes and suture-to-delivery interval after their emergent cerclage. Additionally, BMI, frequency of cerclage and vaginal microecology accounted for higher fetal loss in patients who underwent emergency cerclage.

PROBLEM
The exact biochemical mechanisms that initiate labor are not yet fully understood. Nitric oxide is a potent relaxant of uterine smooth muscles until labor starts, and its precursor is L-arginine. Asymmetric (ADMA) and symmetric (SDMA) dimethylarginines, are potent NO-inhibitors. However, arginines (dimethylarginines and L-arginine) are scarcely studied in relation to labor and childbirth. We aimed to investigate arginines in women with spontaneous (SLVB) and induced (ILVB) term labor with vaginal birth and in women undergoing elective caesarean section (ECS).
METHOD OF STUDY
Women at gestational week 16-18 were recruited to the population-based prospective cohort study BASIC at the Uppsala University Hospital, Sweden. Plasma samples taken at start of labor were analyzed for arginines, from SLVB (n = 45), ILVB (n = 45), and ECS (n = 45), using Ultra-High Performance Liquid Chromatography. Between-group differences were assessed using Kruskal-Wallis and Mann-Whitney U-test.
RESULTS
Women with SLVB and ILVB had higher levels of ADMA (p < .0001), SDMA (p < .05) and lower L-arginines (p < .01), L-arginine/ADMA (p < .0001), and L-arginine/SDMA (p < .01, respectively <.001) compared to ECS. However, ILVB had higher ADMA (p < .0001) and lower L-arginine (p < .01), L-arginine/ADMA (p < .0001), and L-arginine/SDMA (p < .01) compared to SLVB. Results are adjusted for gestational length at birth and cervical dilatation at sampling.
CONCLUSION
Our novel findings of higher levels of dimethylarginines in term vaginal births compared to ECS give insights into the biochemical mechanisms of labor. These findings might also serve as a basis for further studies of arginines in complicated pregnancies and labor.

Review
AIM
The aim of this paper is to present the evidence on the effectiveness of non-surgical interventions to improve health and well-being in women living with Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome.
DESIGN
Systematic review guided by Preferred Reporting Items for Systematic Reviews checklist.
DATA SOURCES
The search was conducted between June and September 2022 across the following databases: CINAHL, EMBASE, Medline, PsycINFO and Cochrane. Trial registries (clinicaltrials. gov, World Health Organization International Clinical Trials Registry Platform (ICTRP), Cochrane Controlled Trials Register-CCTR), Google scholar, dissertations, conference proceedings and reference lists of included studies were also searched. Corresponding authors, formal and informal MRKH groups were contacted to obtain any significant studies or reviews.
REVIEW METHODS
Eligible were only English-language empirical studies of any time period. The review followed narrative synthesis.
RESULTS
Twenty-three studies were identified that fit the inclusion criteria which included 1540 MRKH syndrome affected women. Four studies were on psychological interventions (n = 85) and 19 studies (vaginal dilation therapy n = 897, coital dilation n = 57) focused on non-surgical vaginal dilation as a measure to vaginal agenesis in MRKH syndrome.
CONCLUSIONS
Clearly, vaginal dilation is a viable initial treatment option for women with MRKH syndrome. There is limited evidence that 'coital dilation' is an effective method of dilation for vaginal agenesis. The literature, however, supports the need for psychological intervention to improve health and well-being.
IMPACT
Women with MRKH syndrome who require dilation can receive guidance and support from their healthcare providers, particularly sexual and reproductive health nurses, clinical nurse specialists and gynaecologists. From the point of diagnosis, clinical psychologists should be involved. As much as feasible, family and partner support can be encouraged.

Observational Study
OBJECTIVE
To determine the frequency of successful trials of vaginal birth after Caesarean section (VBAC) using the Flamm and Geiger model.
STUDY DESIGN
Observational study. Place and Duration of the Study: Obstetrics and Gynaecology Unit II of Dr. Ruth K.M. Pfau Civil Hospital, Karachi, Pakistan, from August 2022 to January 2023.
METHODOLOGY
Women with singleton pregnancy having cephalic presentation, previous one lower segment caesarean section (LSCS), and without any contraindication for vaginal delivery were included. Women bearing foetus having estimated weight >3.5kg, morbid obesity, multiple pregnancies, non-cephalic presentation, placenta praevia, abruptio placentae, uncontrolled maternal comorbidities, or had previous two or more Caesarean sections were excluded. Flamm and Geiger score was applied to record observations of successful and unsuccessful trials. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the score were calculated by ROC curve, along with its area under the curve (AUC) and Youden's index curve, with 95% confidence interval.
RESULTS
This study included 258 participants. Successful vaginal delivery was possible in 125 (48.4%) participants, whereas 133 (51.6%) underwent emergency Caesarean section. Cervical dilatation and effacement were the main factors assessing the success. The Flamm and Geiger score of >5 had an area under the curve of 0.813 (0.762-0.864). The score's sensitivity was 75% (67-82%), specificity 76% (68-82%), and PPV of 75% with an accuracy of 76%.
CONCLUSION
The Flamm and Geiger score of >5 demonstrated high sensitivity, specificity, PPV, and accuracy in predicting later successful vaginal birth. It is recommended as a promising and valuable tool for assessing VBAC's success in low-resource countries.

STUDY OBJECTIVE
To describe cases of image-guided drainage of symptomatic hematometrocolpos from obstructive Müllerian anomalies as a temporizing measure to manage acute pain symptoms and delay definitive management of the obstructive Müllerian anomalies that require complex reconstruction METHODS: Institutional Review Board exemption from all included institutions was obtained. A retrospective case series from 3 academic children's hospitals of 8 females under the age of 21 with symptomatic hematometrocolpos due to obstructive Müllerian anomalies drained by image-guided percutaneous transabdominal vaginal or uterine drainage with interventional radiology was reviewed and described.
RESULTS
Eight pubertal patients with obstructive Müllerian anomalies (6 patients with distal vaginal agenesis, 1 patient with an obstructed uterine horn, and 1 patient with a high obstructed hemi-vagina) and symptomatic hematometrocolpos are reported. All patients with distal vaginal agenesis had greater than 3 cm lower vaginal agenesis, which would usually require complex vaginoplasty and use of postoperative stents. Given their immaturity and inability to use stents or dilators postoperatively or medical complexity, they subsequently underwent ultrasound-guided drainage of hematometrocolpos with interventional radiology to relieve pain symptoms, followed by menstrual suppression. The patients with obstructed uterine horns had complex medical and surgical histories requiring perioperative planning; they also underwent ultrasound-guided drainage of hematometra as a temporizing measure to manage acute symptoms.
CONCLUSION
Patients presenting with symptomatic hematometrocolpos due to obstructive Müllerian anomalies might not be psychologically mature enough to undergo definitive complex reconstruction, which requires vaginal stent or dilator use postoperatively to prevent stenosis and other complications. Image-guided percutaneous drainage of symptomatic hematometrocolpos serves as a temporizing measure by offering pain relief until patients are ready to undergo surgical management and/or to allow time for complex surgical planning.

Avicenna Journal of Phytomedicine 2023To determine whether addition of evening primrose to a misoprostol-based abortion regimen can increase the success of abortion.
OBJECTIVE
To determine whether addition of evening primrose to a misoprostol-based abortion regimen can increase the success of abortion.
MATERIALS AND METHODS
In this randomized clinical trial., 148 women referring to Niknafas Hospital in Rafsanajn with diagnosis of missed abortion were randomly allocated into two 74-subject groups. The intervention group used 2000 mg vaginal evening primrose capsules the night before the hospitalization, while the control group did not receive any medication. Both groups received an initial dose of 800 μg of vaginal misoprostol after admission and the next dose was given three hours later if necessary.
RESULTS
The two groups had significant differences in terms of full abortion, consistency and dilatation of cervix, duration between the first dose of misoprostol until the ejection of fetus, the misoprostol dose administered, and the level of vaginal bleeding during the hospitalization. They had no significant differences regarding curettage, duration of hospitalization, or side effects. The mean pain score had no significant difference between the two groups, though the score was lower in the intervention group (p>0.05).
CONCLUSION
Administration of vaginal evening primrose before vaginal misoprostol was found to be more effective compared to misoprostol alone in missed abortion.
