There are more than 13,000 new cases of cervical cancer each year in the United States and approximately 245,000 survivors. External beam radiation and brachytherapy are the front-line treatment modalities, and 60% of patients develop vaginal damage and constriction, i.e., stenosis of the vaginal vault, greatly impeding sexual function. The incidence of vaginal stenosis (VS) following radiotherapy (RT) for anorectal cancer is 80%. VS causes serious quality of life (QoL) and psychological issues, and while standard treatment using self-administered plastic dilators is effective, acceptance and compliance are often insufficient. Based on published patient preferences, we have pursued the design of a soft inflatable dilator for treating radiotherapy-induced vaginal stenosis (VS). The critical component of the novel device is the dilator balloon wall material, which must be compliant yet able to exert therapeutic lateral force levels. We selected a commercially available silicone elastomer and characterized its stress-strain characteristics and hyperelastic properties. These parameters were quantified using uniaxial tensile testing and digital image correlation (DIC). Dilator inflation versus internal pressure was modeled and experimentally validated in order to characterize design parameters, particularly the dilator wall thickness. Our data suggest that an inflatable silicone elastomer-based vaginal dilator warrants further development in the context of a commercially available, well-tolerated, and effective device for the graded, controlled clinical management of radiotherapy-induced VS.

Meta-Analysis Review
OBJECTIVES
The primary objective was to perform a systematic review of predictive factors for obstetric anal sphincter injury (OASI) occurrence at first vaginal delivery, with the diagnosis made by ultrasound (US-OASI). The secondary objective was to report on incidence rates of sonographic anal sphincter (AS) trauma, including trauma that was not clinically reported at childbirth, among the studies providing data for our primary objective.
METHODS
We conducted a systematic search of MEDLINE, EMBASE, Web of Science, CINAHL, The Cochrane Library and ClinicalTrials.gov databases. Both observational cohort studies and interventional trials were eligible for inclusion. Study eligibility was assessed independently by two authors. Random-effects meta-analyses were performed to pool effect estimates from studies reporting on similar predictive factors. Summary odds ratio (OR) or mean difference (MD) is reported with 95% CI. Heterogeneity was assessed using the I statistic. Methodological quality was assessed using the Quality in Prognosis Studies tool.
RESULTS
A total of 2805 records were screened and 21 met the inclusion criteria (16 prospective cohort studies, three retrospective cohort studies and two interventional non-randomized trials). Increasing gestational age at delivery (MD, 0.34 (95% CI, 0.04-0.64) weeks), shorter antepartum perineal body length (MD, -0.60 (95% CI, -1.09 to -0.11) cm), labor augmentation (OR, 1.81 (95% CI, 1.21-2.71)), instrumental delivery (OR, 2.13 (95% CI, 1.13-4.01)), in particular forceps extraction (OR, 3.56 (95% CI, 1.31-9.67)), shoulder dystocia (OR, 12.07 (95% CI, 1.06-137.60)), episiotomy use (OR, 1.85 (95% CI, 1.11-3.06)) and shorter episiotomy length (MD, -0.40 (95% CI, -0.75 to -0.05) cm) were associated with US-OASI. When pooling incidence rates, 26% (95% CI, 20-32%) of women who had a first vaginal delivery had US-OASI (20 studies; I = 88%). In studies reporting on both clinical and US-OASI rates, 20% (95% CI, 14-28%) of women had AS trauma on ultrasound that was not reported clinically at childbirth (16 studies; I = 90%). No differences were found in maternal age, body mass index, weight, subpubic arch angle, induction of labor, epidural analgesia, episiotomy angle, duration of first/second/active-second stages of labor, vacuum extraction, neonatal birth weight or head circumference between cases with and those without US-OASI. Antenatal perineal massage and use of an intrapartum pelvic floor muscle dilator did not affect the odds of US-OASI. Most (81%) studies were judged to be at high risk of bias in at least one domain and only four (19%) studies had an overall low risk of bias.
CONCLUSION
Given the ultrasound evidence of structural damage to the AS in 26% of women following a first vaginal delivery, clinicians should have a low threshold of suspicion for the condition. This systematic review identified several predictive factors for this. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Review
A number of methods are currently used to predict the optimal date of insemination of the breeding bitch, particularly with the use of frozen-thawed canine semen which has a far shorter lifespan than fresh semen. Aside from confirming cytological oestrus, vaginal cytology is of no assistance in predicting the most fertile day(s) in a bitch; however, a neglected avenue of research suggests that vaginal cytology may be of great importance in confirming the days of optimal fertility retrospectively. Similarly, vaginoscopy provides clues as to the stage of a bitch's cycle but is inadequate as a sole determinant of her most fertile days. Nevertheless, vaginoscopy is useful to identify very late oestrus and the onset of dioestrus, as well as Stage I of labour (cervical dilatation). Due to variations in the rate at which circulating progesterone concentrations rise in individual bitches, the reliability of circulating progesterone concentrations for determining the optimal day(s) of insemination with frozen-thawed semen decreases as values rise. Moreover, progesterone assay results can vary widely due to extrinsic factors such as the time of blood sampling, sample storage conditions and the assay employed. Finally, this review investigates evidence surrounding various insemination routes and suggests that well-performed vaginal insemination, even with frozen-thawed semen, may be an acceptable approach for cases where transcervical insemination is impractical.

PURPOSE OF REVIEW
The goal of this review is to provide a comprehensive overview of hydrometrocolpos, covering disease etiology, pathophysiology, clinical presentation, and diagnostic and management techniques, and known outcomes.
RECENT FINDINGS
This narrative review presents the literature on hydrometrocolpos in the pediatric population from the past 5 years. We highlight the 69 reported cases of hydrometrocolpos and classify them based on type of obstruction or associated anomaly, discuss new diagnostic algorithms based on imaging, and present novel and underutilized surgical techniques for definitive management. Hydrometrocolpos, a condition characterized by retained fluid causing a distended vagina and uterus in the setting of a distal vaginal outflow obstruction, has a wide range of presentation severity based on the type of obstruction. Whether hydrometrocolpos is due to an isolated condition like imperforate hymen, a complex abnormality like cloacal malformation, or a part of a large congenital syndrome, the mainstay of treatment is decompression of the dilated vagina and surgical correction of the outflow obstruction. Imaging-based diagnostic algorithms and new treatment techniques reported in the literature, as well as longitudinal and patient-reported outcome research, can improve the lives of children affected by this condition.

Review
INTRODUCTION
Retained products of conception (RPOC) generally result after first half of pregnancy termination and also may occur after vaginal or cesarean delivery. It frequently presents with irregular or continuous vaginal bleeding, lower abdominal and pelvic pain, and discharge per vaginum due to infection; it can also cause late complications like formation of intrauterine adhesions and subfertility. The diagnosis of the RPOC along with the symptoms is generally supported by ultrasonography with or without colour Doppler. The patient also undergoes uterine vasculature assessment to diagnose arteriovenous malformation (AVM). The management of RPOC has been conventionally done with blind dilation and suction curettage (D and C); however, expectant management, uterine artery embolization, and hysteroscopic resection of RPOC are safe and efficient alternatives.
MATERIALS AND METHODS
In this review, we analyse the current available evidence regarding the clinical presentation, diagnosis and treatment of RPOC comparing the sensitivity, specificity, outcomes, pros and cons of various methods.
CONCLUSION
RPOC is a common complication associated with early and late complications. The judicious use of antibiotics along with interventional radiology and hysteroscopy forms the backbone for the treatment of this condition.

Brachytherapy (BT) plays a fundamental role in the treatment of gynecological cancers. Patient education for vaginal self-management and dilator use post-BT involves an interdisciplinary team of healthcare professionals (HCPs) and there is a paucity of post-BT education guidelines. Our objective was to determine the educational needs of gynecological cancer patients surrounding vaginal self-management post-BT and to determine enablers and barriers to the provision of education by HCPs. This cross-sectional study recruited gynecological oncology patients receiving external beam radiotherapy and BT for curative intent. Patients completed a questionnaire to assess their vaginal self-management educational needs, preferred education modality, and desired timing of post-BT education. HCPs were invited to complete a questionnaire to identify enablers and barriers to providing BT education. Twenty patients and 53 HCPs participated. All patients rated each topic as very important/important with information about preventing vaginal stenosis as the most important overall (89%). When asked about topics they addressed during BT education, most HCPs reported that "explaining what vaginal stenosis is and the negative effects of stenosis" was always discussed with patients (N = 37/49, 77%). Barriers to providing post-BT education, including the patients' language and culture, as well as enablers, such as the use of written resources and tools for patients, were identified. Despite a high level of engagement, current education surrounding vaginal self-management post-BT may be inadequate.

Review
This review assessed the efficacy and safety of pharmacologic agents (prostaglandins, oxytocin, mifepristone, hyaluronidase, and nitric oxide donors) and mechanical methods (single- and double-balloon catheters, laminaria, membrane stripping, and amniotomy) and those generally considered under the rubric of complementary medicine (castor oil, nipple stimulation, sexual intercourse, herbal medicine, and acupuncture). A substantial body of published reports, including 2 large network meta-analyses, support the safety and efficacy of misoprostol (PGE1) when used for cervical ripening and labor induction. Misoprostol administered vaginally at doses of 50 μg has the highest probability of achieving vaginal delivery within 24 hours. Regardless of dosing, route, and schedule of administration, when used for cervical ripening and labor induction, prostaglandin E2 seems to have similar efficacy in decreasing cesarean delivery rates. Globally, although oxytocin represents the most widely used pharmacologic agent for labor induction, its effectiveness is highly dependent on parity and cervical status. Oxytocin is more effective than expectant management in inducing labor, and the efficacy of oxytocin is enhanced when combined with amniotomy. However, prostaglandins administered vaginally or intracervically are more effective in inducing labor than oxytocin. A single 200-mg oral tablet of mifepristone seems to represent the lowest effective dose for cervical ripening. The bulk of the literature assessing relaxin suggests this agent has limited benefit when used for this indication. Although intracervical injection of hyaluronidase may cause cervical ripening, the need for intracervical administration has limited the use of this agent. Concerning the vaginal administration of nitric oxide donors, including isosorbide mononitrate, isosorbide, nitroglycerin, and sodium nitroprusside, the higher incidence of side effects with these agents has limited their use. A synthetic hygroscopic cervical dilator has been found to be effective for preinduction cervical ripening. Although a pharmacologic agent may be administered after the use of the synthetic hygroscopic dilator, in an attempt to reduce the interval to vaginal delivery, concomitant use of mechanical and pharmacologic methods is being explored. Combining the use of a single-balloon catheter with dinoprostone, misoprostol, or oxytocin enhances the efficacy of these pharmacologic agents in cervical ripening and labor induction. The efficacy of single- and double-balloon catheters in cervical ripening and labor induction seems similar. To date, the combination of misoprostol with an intracervical catheter seems to be the best approach when balancing delivery times with safety. Although complementary methods are occasionally used by patients, given the lack of data documenting their efficacy and safety, these methods are rarely used in hospital settings.

OBJECTIVES
Well-established clinical practice to assess progress in labor involves routine abdominal palpation and vaginal examination (VE). However, VE is subjective, poorly reproducible and painful for women. In this study, our aim is to evaluate the feasibility of systematically integrating transabdominal and transperineal ultrasound assessment of fetal position, psAOP, HPD and SCD to monitor labor progress in women undergoing induction of labor (IOL). We also aim at determining if ultrasound can reduce women's pain during examinations.
METHODS
Women were recruited as they presented for IOL in three maternity units. Ultrasound assessments were performed in 100 women between 37 and 41 weeks' gestation. A baseline combined transabdominal and transperineal scan was performed, including the assessment of fetal biometry, umbilical artery and middle cerebral artery Dopplers, amniotic fluid index (AFI), fetal spine and occiput positions, psAOP, HPD, SCD, and cervical length. Intrapartum scans were performed instead of VEs according to protocol. Participants were asked to indicate their level of pain by verbally giving a pain score from 0 - 10 (with 0 representing no pain) during assessment. The repeated measures data were analyzed by mixed effect models to identify the significant factors that affected the relationship between psAOP, HPD, SCD and mode of delivery.
RESULTS
223 intrapartum ultrasound scans with a median of 2 scans per participant (interquartile range (IQR) = 1 - 3), and 151 VEs were performed with a median of 1 per participant (IQR = 0 - 2). There were no adverse fetal or maternal outcomes. After excluding those with epidural anesthesia during examination, median pain score for intrapartum scan was 0 (IQR = 0 - 1) and 3 for VE (IQR = 0 - 6). Cesarean delivery and epidural anesthesia were significantly associated with slower rate of change in psAOP, HPD and SCD. Maternal height, parity and neonatal birth weight did not affect ultrasound measurements of labor progress.
CONCLUSIONS
Comprehensive transabdominal and transperineal ultrasound assessment can be successfully used to assess progress in labor and can reduce the level of pain experienced during examination. Ultrasound assessment may be able to replace some transabdominal and VE examinations during labor. This article is protected by copyright. All rights reserved.

The Journal of Sexual Medicine Dec 2023Unconsummated marriage (UCM) is the inability of the heterosexual married couple to have penovaginal sexual intercourse.
BACKGROUND
Unconsummated marriage (UCM) is the inability of the heterosexual married couple to have penovaginal sexual intercourse.
AIM
The study sought to systematically review current evidence regarding the etiological factors and clinical management of UCM.
METHODS
A comprehensive bibliographic search on the MEDLINE, Scopus, Web of Science, and Cochrane Library databases was performed in June 2023. Studies were selected if they described married couples who never had sexual intercourse in case report or case series evaluating the related causes and/or management and reporting data with qualitative, quantitative, or mixed methods. The review was reported according to PRISMA (Preferred Reporting Items for Systematic Review and Meta-analyses) statement and registered in PROSPERO with ID CRD42023433040.
RESULTS
A total of 27 studies including 1638 males and 1587 females were selected. Eight (29.6%) articles were case reports involving a single couple and 19 (70.4%) studies were case series. Mean Murad score was 4.1 (range, 1-8) showing low-intermediate overall study quality. All articles had a level of evidence of 4. Most of studies were conducted in Egypt (n = 5 [18.4%]), Israel (n = 4 [14.9%]), and the United States (n = 4 [14.9%]). The mean age of males and females varied between 24.2 and 37.6 years and from 21 to 27.4 years, respectively. The reasons for the medical visit that led to the diagnosis of UCM were inability to consummate in 23 (85.2%) studies, inability to conceive in 1 (3.7%) article, and mixed in 3 (11.1%) articles. The mean duration of UCM varied from 7 days to 3.5 years. Eight studies involving both men and women showed that vaginismus (8.4%-81%) and erectile dysfunction (10.5%-61%) were the most common causes of UCM. Three articles reported that 16.6% to 26% of all UCM cases were due to both male and female factors. Sildenafil, tadalafil, intracavernosal injection, penile plication, female genital reconstructive surgery, vaginal dilators, lubricants, psychosexual therapy, and sex education were the various treatment modalities in 27 studies to achieve consummation rate of 66.6% to 100%.
STRENGTHS & LIMITATIONS
A strength is that this is the first systematic review covering the entire spectrum of UCM. Limitations comprised the low quality of most of the included articles and the large percentage of UCM cases probably not published.
CONCLUSION
Erectile dysfunction and vaginismus are the most reported causes of UCM; however, a strong psychological component certainly underlies a significant number of cases. A multidisciplinary approach based on strategic integration of sex education, medical therapy, psychosexual support, and surgical treatment would seem the most suitable option to manage couples with UCM.

Twins represent 3.2% of all live births. However, they account for 20% of all preterm deliveries, 60% delivering <37 weeks, 10.7% <32 weeks, and 5 times higher risk of infant death. Risk factors for preterm birth (PTB) include the history of preterm delivery, monochorionic twins, short cervical length, and cervical surgery. Transvaginal cervical length <24 weeks is the best tool to predict PTB. Only vaginal progesterone in women with transvaginal cervical length <25 mm and physical exam indicated cerclage in women with cervical dilation >1 cm have shown a significant decrease in PTB and improvement in neonatal outcomes.
