Protocol for an intervention for new parents experiencing moderate psychosocial adversity: pilot feasibility randomised trial.

BACKGROUND: Parents exposed to psychosocial adversities often experience challenges which, combined with the needs of a new-born infant, can be difficult to manage and increase the risk of poor outcomes for both parents and infants. Psychosocial adversity can disrupt the development of parental-foetal attachment to the baby during pregnancy, which can have a negative effect on parental care and quality of interaction during the postnatal period. This intervention is based on the proposition that enhanced parental capacity to mentalise and emotionally connect to unborn children during pregnancy, and better understanding about how to manage distressing infant behaviour (i.e., persistent crying and sleep problems) will: (i) promote the development of secure parent-infant attachment; (ii) improve antenatal bonding and postnatal parenting; and, (ii) reduce parental distress. METHOD: This protocol is for a pilot randomised control trial evaluating a new intervention, which makes use of innovative technologies to support parents experiencing moderate psychosocial adversity (Australian New Zealand Clinical Trials Registry: ACTRN12622000287730). The New Technology for New Parents (NTNP) intervention provides support using antenatal ultrasound scans and 'virtual home visits' during the perinatal period. Quantitative outcomes include mentalising capacity, parental-foetal/infant attachment, and parental competence. CONCLUSION: To the best of our knowledge, no study has evaluated the combined effectiveness of two novel technologies (3D/4D ultrasound scans and virtual home visits) to support parents across the antenatal and postnatal periods. This protocol, which includes the rationale for this innovative intervention, addresses a gap in services for parents experiencing moderate psychosocial adversity.

Longitudinal Study of Pelvic Floor Characteristics Before, During, and After Pregnancy in Nulliparous Women.

OBJECTIVES: To investigate the changes in the pelvic floor before, during, and after pregnancy in the same collective of nulliparous women. METHODS: In a prospective observational pilot study between April 2015 and June 2019 in nulliparous women with planned pregnancy, we used the pelvic organ prolapse quantification (POP-Q) system; a 2-dimensional (2D) sonography to investigate the bladder neck, cervix, and anorectal junction positions; and a 3D/4D sonography to measure the hiatus of the levator ani muscle (LH area) during Valsalva maneuver. Five visits were planned: 1 before, 3 during, and 1 visit after pregnancy. RESULTS: Twenty-four women participated in the study. We achieved a minimum of 2 visit measurements from 10 women who became pregnant. The LH area decreased during the first trimester and then increased until the third trimester. Postpartum, the LH area reached the prepregnancy state. We observed changes in the bladder neck mobility, bladder neck position, cervix, and anorectal junction from the first trimester. Postpartum, the bladder neck mobility was higher, and the position of the bladder neck and anorectal junction was lower than before pregnancy. We observed no remarkable changes in the POP-Q state during pregnancy. CONCLUSION: This was the first study to investigate pelvic floor characteristics in the same collective before, during, and after pregnancy. We observed pelvic floor changes from the prepregnancy state to the first trimester to postpartum. The study results need to be confirmed in a larger study.

The correlation between transperineal ultrasound assessment of the levator ani muscle and postpartum urinary incontinence.

AIMS: The primary aim of the present study was to assess the association between levator ani muscle (LAM) integrity and function on the one hand, and the risk of urinary incontinence (UI) on the other. A secondary objective was to assess the association between fundal pressure in the second stage of labor (Kristeller maneuver) and the risk of postpartum UI. METHODS: In this prospective cohort study, women underwent a clinical and transperineal ultrasound examination at rest, at pelvic floor muscle contraction (PFMC), and at Valsalva maneuver 3-6 months after their first vaginal delivery. LAM avulsion and levator hiatal area (LHA) were evaluated. In addition, women were interviewed about the presence of UI, whether stress (SUI) or urgency (UUI). RESULTS: Overall, data of 244 women were analyzed. SUI was reported in 50 (20.5%), while UUI was reported in 19 (7.8%) women. Women who reported SUI had a higher prevalence of LAM avulsion and less proportional reduction in LHA from rest to a maximum contraction in comparison to women with no SUI. Women who reported UUI had a greater LHA at rest, during contraction, and during maximal Valsalva in comparison to women without UUI. No significant association was found between the Kristeller maneuver and the incidence of any UI. CONCLUSION: Levator ani avulsion and less proportional reduction of LHA with PFMC appear to be associated with a higher risk of postpartum urinary stress incontinence.

Location of obstetric anal sphincter injury scars on translabial tomographic ultrasound.

OBJECTIVE: Obstetric anal sphincter injury (OASI) is a common preventable cause of anal incontinence. Both diagnosis and primary repair of OASI are often suboptimal, partly owing to the absence of effective clinical audit. The aim of this study was to evaluate the location of scars or defects of the external anal sphincter (EAS), diagnosed by translabial ultrasound (TLUS), following primary OASI repair. METHODS: This was a retrospective analysis of 309 women who were seen at a tertiary obstetric unit after primary repair of OASI between June 2012 and May 2019. All women underwent a standardized interview, including St Mark's incontinence score, followed by clinical examination and TLUS assessment within 2-9 months after OASI repair. Postprocessing of TLUS volume datasets was performed by an investigator who was blinded to all other information. Tomographic ultrasound imaging was used to evaluate the presence of a scar or defect in the proximal and distal parts of the EAS. Women were classified into four groups according to the imaging findings: (1) no visible defect or distortion (likely false positive); (2) only proximal OASI; (3) only distal OASI; and (4) both proximal and distal OASI. RESULTS: Of the 309 women seen during the study period, 34 were excluded because they were referred for reasons other than recent (< 1 year) OASI, 16 owing to missing data and four owing to poor image quality, leaving 255 patients for analysis. Women were seen on average 0.25 ± 0.1 years after the index birth, and their mean age at delivery was 29.1 ± 4.6 years. Anal incontinence was reported by 97 (38.0%) women. A scar or defect was seen only in the proximal part of the EAS in 64 (25.1%) women and only in the distal part in 19 (7.5%) (P < 0.001). In 165 (64.7%) women, the damage affected both the proximal and distal EAS. CONCLUSIONS: EAS scars after primary OASI repair commonly affect the entire length of the EAS; however, partial tears seem to be more likely to occur proximally. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Is pelvic floor muscle contractility an important factor in anal incontinence?

OBJECTIVE: Pelvic floor muscle contractility (PFMC) may contribute to anal continence. The aim of this study was to assess the association between clinical and sonographic measures of PFMC and anal incontinence (AI) symptoms, after controlling for anal sphincter and levator ani muscle (LAM) trauma. METHODS: This was a retrospective study of 1383 women assessed at a tertiary center between 2013 and 2016. All patients underwent an interview, including the St Mark's incontinence score (SMIS) in those who reported AI symptoms, a clinical examination, including assessment of PFMC using the modified Oxford scale (MOS), and four-dimensional translabial ultrasound (TLUS). Sonographic measures of PFMC, i.e. cranioventral shift of the bladder neck (BN) and reduction of anteroposterior (AP) diameter of the levator hiatus, were measured offline using ultrasound volumes obtained at rest and on maximum pelvic floor contraction. The reviewer was blinded to all clinical data. RESULTS: Of the 1383 patients assessed during the study period, seven were excluded due to missing imaging data, leaving 1376 for analysis. Mean age of the participating women was 55 years and mean body mass index was 29 kg/m2 . AI was reported by 221 (16.1%) women, with a mean SMIS of 11.8. Mean MOS grade was 2.3. On TLUS, mean BN cranioventral shift was 5.9 mm and mean AP diameter reduction was 8.1 mm. LAM avulsion and significant external anal sphincter (EAS) defect were diagnosed in 24.8% and 8.7% patients, respectively. On univariate analysis, sonographic measures of PFMC were not associated with AI. Lower MOS grade was associated with symptoms of AI; however, statistical significance was lost on multivariate analysis. CONCLUSION: Clinical and sonographic measures of PFMC were not significantly associated with AI symptoms after controlling for EAS and LAM trauma. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

Comparison of Abdominal Aortic Aneurysm Sac and Neck Wall Motion with 4D Ultrasound Imaging.

OBJECTIVE: The rupture of abdominal aortic aneurysms (AAAs) is associated with high mortality despite surgical developments. The determination of aneurysm diameter allows for follow up of aneurysm growth but fails in precisely predicting aneurysm rupture. In this study, time resolved three dimensional ultrasound (4D ultrasound) based wall motion indices (WMIs) are investigated to see if they are capable of distinguishing between uneven affected regions of the aneurysm wall. METHODS: In a prospective study, 56 patients with an AAA were examined using 4D ultrasound. Local longitudinal, circumferential, and shear strains were computed using custom methods. The deformation of the neck and sac of each aneurysm was characterised by statistical indices of the obtained distributions of local wall strains (WMIs): mean and peak strain, heterogeneity index, and local strain ratio. The locations of regions with highest local peak strain were determined. RESULTS: Compared with the aneurysm neck, the sac is characterised by low mean strain, but highly heterogeneous deformation, described by high local strain ratio and heterogeneity index. Differences were highly significant (p < .001) for all strain components. The regions with the highest circumferential peak strain were found more often in the posterior part of the aneurysm neck (p < .050) and sac (p < .001) regions, compared with other wall regions. No statistically significant correlation was found between the WMIs and maximum AAA diameter, except for longitudinal mean strain, which decreased with the increasing diameter (rho = -.42, p < .010). CONCLUSION: Characterisation of wall kinematics by 4D ultrasound based WMIs provides a new and independent criterion for the distinction of diseased tissue in the AAA sac and the less affected neck region. This is a promising step towards the establishment of new biomarkers to differentiate between the mechanical instability of the AAA and rupture risk.

Vaginal laxity: which measure of levator ani distensibility is most predictive?

OBJECTIVE: To assess the predictive value of measures of levator hiatal distension at rest and on maximum Valsalva maneuver for symptoms of vaginal laxity. METHODS: This was a retrospective study of women seen at a tertiary urogynecological unit. All women underwent a standardized interview, clinical examination and four-dimensional translabial ultrasound examination. Area, anteroposterior diameter (APD) and coronal diameter (CD) of the levator hiatus were measured at rest and on maximum Valsalva maneuver in the plane of minimal hiatal dimensions using the rendered volume technique, by an operator blinded to all clinical data. The association between levator hiatal measurements and vaginal laxity was assessed, and receiver-operating-characteristics (ROC)-curve analysis was used to determine their predictive value. RESULTS: Data from 490 patients were analyzed. Mean age was 58 (range, 18-88) years, and vaginal laxity was reported by 111 (23%) women. Measurements obtained on maximum Valsalva were significantly larger in women who reported vaginal laxity than in those who did not, with mean levator hiatal area, APD and CD of 30.45 ± 8.74 cm2 , 7.24 ± 1.16 cm and 5.60 ± 0.89 cm, respectively, in the vaginal-laxity group, compared with 24.84 ± 8.63 cm2 , 6.64 ± 1.22 cm and 5.01 ± 0.97 cm in the no-laxity group (P < 0.001 for all). Measurements obtained at rest were not significantly different between the groups. Multiple logistic regression analysis controlling for age, body mass index, vaginal parity and levator avulsion confirmed these results. The best regression model for the prediction of vaginal laxity included age, vaginal parity and levator hiatal area on maximum Valsalva. ROC-curve analysis of levator hiatal measurements on maximum Valsalva in the prediction of vaginal laxity demonstrated areas under the curve of 0.68 (95% CI, 0.63-0.73) for area, 0.63 (95% CI, 0.57-0.68) for APD and 0.68 (95% CI, 0.62-0.73) for CD. CONCLUSIONS: Levator hiatal area on maximum Valsalva seems to be the measure of levator ani distensibility that is most predictive of symptoms of vaginal laxity. Copyright © 2019 ISUOG.

Prenatal effects of maternal nutritional stress and mental health on the fetal movement profile.

PURPOSE: Prenatal sub-optimal nutrition and exposure to maternal stress, anxiety and depression in pregnancy have been linked to increased postnatal morbidity and mortality. Fetal growth is most vulnerable to maternal dietary deficiencies, such as those evident in hyperemesis gravidarum (HG), early in pregnancy. The purpose of this pilot study was to examine the effects of HG on fetal movement profiles as a measure of fetal healthy development in the 3rd trimester of pregnancy, and to assess whether nutritional stress on the mother can be evaluated using isotopic analysis of hair. METHOD: We analyzed fetal movement profiles using 4D ultrasound scans at 32- and 36-weeks' gestation. Fetuses of women (N = 6) diagnosed with HG, having lost more than 10% of their body weight in the first trimester of pregnancy were compared to a healthy group (N = 6), controlling for stress, depression and anxiety. We tested carbon and nitrogen isotope ratios in maternal hair as a measure of both diet and nutritional changes due to catabolism of body proteins and fats. RESULTS: HG and catabolism were significantly correlated (p = 0.02). Furthermore, at 32-weeks' gestation movement profiles of fetuses of mothers with HG differed significantly from the movement profiles of fetuses of healthy mothers. Fetuses of mothers suffering from HG showed a significantly increased ratio of fine-grained movements at 32 weeks (p = 0.008); however, there were no significant differences detectable at 36-weeks' gestation. CONCLUSION: The effect of HG on fetal development as expressed by variations in fetal movement profiles in this pilot study suggest that prenatal effects of HG can be measured using movement profiles. Isotope analysis of hair can supplement this with information on nutritional imbalances early in pregnancy.

Association between pelvic floor muscle trauma and contraction in parous women from a general population.

OBJECTIVE: To study possible associations between pelvic floor muscle contraction, levator ani muscle (LAM) trauma and/or pelvic organ prolapse (POP) ≥ Stage 2 in parous women recruited from a general population. METHODS: This was a secondary analysis of data from a cross-sectional study of 608 parous women from a general population examined using the POP quantification system (POP-Q) and three-dimensional/four-dimensional transperineal ultrasound for identification of LAM macrotrauma (avulsion) and microtrauma (distension of levator hiatal area > 75th percentile on Valsalva maneuver). Muscle contraction was assessed using the modified Oxford scale (MOS), perineometry and ultrasound measurement of proportional change of anteroposterior hiatal diameter and levator hiatal area at rest and on pelvic floor muscle contraction. The Mann-Whitney U-test was used to study associations between pelvic floor muscle contraction, LAM trauma and POP. RESULTS: Women with macrotrauma (n = 113) had significantly weaker median pelvic floor muscle contraction, as measured using MOS and perineometry, than did women with an intact LAM (n = 493) (contraction strength was 1.5 (range, 0.0-5.0) vs 3.5 (range, 0.0-5.0) on MOS, and vaginal squeeze pressure was 15.0 (range, 0.0-78.0) cmH2 O vs 28.0 (range, 0.0-129.0) cmH2 O on perineometry; P < 0.001). This was also demonstrated by ultrasound measurement, with a proportional change in hiatal area of 19.9% (range, 4.1-48.0%) vs 34.0% (range, 0.0-64.0%) (P < 0.001) and proportional change in anteroposterior diameter of 16.2% (range, -5.7 to 42.6%) vs 26.0% (range, -3.4 to 49.4%) (P < 0.001). No statistically significant difference between women with (n = 65), and those without (n = 378), microtrauma was found after excluding women with macrotrauma. Women with POP had weaker muscle contraction than those without; in those with POP-Q ≥ 2 (n = 275) compared with those with POP-Q < 2 (n = 333), muscle contraction strength was 3.0 (range, 0.0-5.0) vs 3.5 (range, 0.0-5.0) on MOS, vaginal squeeze pressure was 21.0 (range, 0.0-98.0) cmH2 O vs 28.0 (range, 3.0-129.0) cmH2 O on perineometry, proportional change in hiatal area was 29.6% (range, 0.0-60.9%) vs 33.8% (range, 0.0-64.4%) and proportional change in anteroposterior diameter was 22.8% (range, -5.7 to 49.4%) vs 25.7% (range, -3.4 to 49.4%) (P < 0.001 for all). CONCLUSIONS: LAM macrotrauma was associated with weaker pelvic floor muscle contraction measured using palpation, perineometry and ultrasound. Women with POP had weaker contraction than did women without POP. Copyright © 2018 ISUOG. Published by John Wiley & Sons Ltd.

Effect of psychotropic drugs on fetal behavior in the third trimester of pregnancy.

AIM: To assess the effect of psychotropic drugs on fetal behavior using four-dimensional (4D) ultrasound in the third trimester of pregnancy. METHODS: Fetal behavior was assessed using Kurjak's antenatal neurodevelopmental test (KANET) using 4D ultrasound between 28 and 36 weeks of gestation. Thirty healthy (control group) and 10 psychotropic-drug-administered pregnant (case group) women were studied. The total value of the KANET score and values of each parameter (eight parameters) were compared between the two groups. RESULTS: The total KANET score was normal (except for one fetus in the case group: total score of 9) in both groups, and there was no significant difference in the total KANET score. When individual KANET parameters were compared, no significant differences were noted in any of the eight parameters. CONCLUSION: Our results showed that there is no difference in fetal behavior between fetuses of normal pregnant women and those of psychotropic-drug-administered pregnant women in the third trimester of pregnancy. These results suggest that psychotropic drugs may not affect fetal behavioral development in utero. However, the data and their interpretation in the present study should be taken with some degree of caution because of the small number of subjects studied. Further studies involving a larger sample size are needed to assess the effect of psychotropic drugs on fetal neurobehavior during pregnancy.

Neurological development may be accelerated in growth-restricted fetuses: a 4D ultrasound study.

Objective To assess whether neurological maturation and development are accelerated in fetal growth restriction (FGR) in utero using four-dimensional (4D) ultrasound. Methods The facial expressions of 50 appropriate-for-gestational-age (AGA) and 34 FGR fetuses aged between 28 and 35 gestational weeks were assessed using 4D ultrasound. Subsequently, they were differentiated into two gestational age groups (19 aged 28-31 weeks and 31 aged 32-35 weeks in AGA, and 15 aged 28-31 weeks and 19 aged 32-35 weeks in FGR). Fifteen-minute recordings were made, and the frequencies of seven facial expressions during that time were examined. Correlation analysis was conducted to assess the changing number of significant correlations with advancing gestation in each group. Results Out of 21 combinations of facial expressions at 28-31 and 32-35 gestational weeks in AGA fetuses, there was only three significant correlations. Similarly, only one was noted out of 21 combinations at 28-31 gestational weeks, but there were seven significant correlations in FGR fetuses at 32-35 weeks (P=0.018). However, there was no significant difference in the number of correlations of facial expressions between AGA (3/21) and FGR (7/21) fetuses at 32-35 weeks of gestation (P=0.147). Conclusion Our results suggest that the number of significant correlations of fetal facial expressions in FGR fetuses increases more compared with that in AGA fetuses at 32-35 weeks of gestation. Due to the acceleration of neurological maturation and development in FGR fetuses, the control of facial expressions by the brain may be more evident compared with AGA fetuses at 32-35 weeks of gestation. However, the data and their interpretation in the present study should be taken with some degree of caution because of the small number of subjects studied. Further studies involving a larger sample size are needed to obtain strong or additional evidence.

Change in fetal behavior in response to vibroacoustic stimulation.

Objective To assess fetal behavioral changes in response to vibroacoustic stimulation (VAS) in normal singleton pregnancies using four-dimensional (4D) ultrasound. Methods Ten types of fetal movements and facial expressions in 68 healthy pregnant women between 24 and 40 weeks were studied using 4D ultrasound for 3 min before and after 3-s VAS. The frequencies of mouthing, yawning, tongue expulsion, back arch, jerky arm movement, startle movement, smiling, scowling, hand-to-face movement, and blinking were evaluated. The fetuses were subdivided into four gestational age groups (24-27, 28-31, 32-35, and ≥36 weeks). Comparison of the frequencies of the fetal behaviors before and after the stimulation in each gestational age group was conducted to detect the response to stimulation with advancing gestation. Results There were no significant differences in the frequency of each fetal behavior before and after VAS at 24-27, 28-31, and 32-35 weeks of gestation. However, the frequencies of blinking and startle movements were significantly higher after VAS in the 36-40 gestational age group (P < 0.05). Conclusion The age of 36 weeks of gestation might represent an advanced stage of brain and central nervous system development and maturation as the response to stimuli is prominent at this age compared with earlier gestation.

Twin fetal facial expressions at 30-33+6 weeks of gestation.

Objective To assess the characteristics of twin fetal facial expressions at 30-33 + 6 weeks of gestation using four-dimensional (4D) ultrasound to clarify twin fetal brain development and maturation. Methods Frequencies of seven fetal facial expressions were studied using 4D ultrasound for 15 minutes in 30 singleton pregnancies and 18 twin pregnancies [four monochorionic diamniotic (MD) and 14 dichorionic diamniotic (DD) twins] at 30-33 + 6 weeks of gestation. Comparison of the frequency in each facial expression was performed between singleton and twin fetuses. Results Mouthing was the most frequent facial expression at 30-33 + 6 weeks of gestation, followed by blinking in twin and singleton fetuses. Both facial expressions were significantly more frequent than other expressions (P < 0.05). The frequencies of mouthing and scowling in twin fetuses were significantly lower than those in singleton fetuses, but there were no significant differences in the frequencies of the five other facial expressions between the fetal groups. Conclusion Our results suggest that restricted twin fetal behavior before 20 weeks of gestation may still affect the frequencies of twin facial expressions early in the third trimester of pregnancy. Moreover, the frequencies of facial expressions in twins are different from those of singleton fetuses.

New three-dimensional/four-dimensional volume rendering imaging software for detecting the abnormally invasive placenta.

OBJECTIVE: This study aimed to determine the role of three-dimensional (3D)/four-dimensional (4D) volume rendering ultrasound (VRU) in the diagnosis of abnormally invasive placenta (AIP). MATERIALS AND METHODS: Twelve consecutive patients strongly suspected of having AIP on the basis of conventional ultrasound (US) and clinical history performed between September 2016 and December 2016 in the main tertiary referral hospital in Surabaya, East Java were included in this prospective observational study. A Samsung WS 80A Elite US scanner with a 3D/4D "crystal vue" and "realistic vue" volume rendering mode was used to establish the diagnosis of AIP and evaluate the site, and depth of placental invasion. The VRU images were compared with the intraoperative findings. RESULTS: Using this novel US technique, all cases of suspected AIP were subsequently confirmed during surgery. Importantly, the new US technique provided a correct diagnosis of the degree of invasion in 11 out of these 12 suspected AIP cases: 5/5 for placenta percreta, 3/3 for placenta increta, and 2/3 for placenta accreta; one patient was misdiagnosed in terms of the degree of placenta accreta, and one patient had normal implantation). CONCLUSION: This new software of 3D/4D VRU represents a promising technique for the preoperative diagnosis and staging of AIP.

Ultrasound study of fetal movements in singleton and twin pregnancies at 12-19 weeks.

Objective To evaluate fetal behavioral differences between singleton and twin fetuses before 20 weeks of gestation using four-dimensional (4D) ultrasound. Methods 4D ultrasound was used to examine fetal movements in 58 singleton and 48 twin normal fetuses at 12-19 weeks. The frequencies of eight fetal movements were assessed through 15-min recordings. The fetuses were divided into two gestational age groups (12-13 and 14-19 weeks) to evaluate the changes with advancing gestation in twin versus singleton fetuses. Results Arm and general movements were the most frequent movements in singleton fetuses, whereas only general movement was significantly more frequent than the other seven fetal movements in twin fetuses at 12-13 weeks. At 14-19 weeks, frequencies of arm and leg movements were significantly higher than those of the other six movements in singleton fetuses, while only arm movement was significantly more frequent than the other fetal movements in twin fetuses. Comparisons of fetal movements between singleton and twin fetuses revealed that only arm movement showed a significant difference at 12-13 weeks, while the frequencies of all movements in singleton fetuses were significantly higher than those in twin fetuses at 14-19 weeks. Conclusion Our results suggest that the limitation of available space and crowding of twin fetuses with advancing gestation may have a marked impact on twin fetal movements compared with singleton fetuses, even in the first half of pregnancy. Further studies are needed to assess whether decreased fetal movements in twin pregnancy can affect fetal and neonatal development and maturation before and after birth.

Prediction of postnatal developmental disabilities using the antenatal fetal neurodevelopmental test: KANET assessment.

Objective To assess the usefulness of the antenatal fetal neurodevelopmental test for the prediction of postnatal developmental disabilities. Methods Fetal behavior was assessed with Kurjak's antenatal neurodevelopmental test (KANET) using four-dimensional ultrasound between 28 and 38 weeks of gestation. A score range of 0-5 was characterized as abnormal, from 6 to 9 was considered borderline, and 10-16 was normal. After birth, follow-up was conducted for at least 2 years in all fetuses. Results There were 337 normal (95.47%) and 16 borderline (4.53%) cases among the 353 cases studied, whereas there was no abnormal case. Five cases with postnatal developmental disabilities (one case of Werdig-Hoffmann disease diagnosed just after delivery, one case of autism spectrum disorder diagnosed at 24 months, one case of Ullrich congenital muscular dystrophy diagnosed at 9 months and two cases of developmental disorders diagnosed at age 3 and 18 months) were noted among the 337 normal cases (1.48%), whereas three cases with developmental disabilities (one case of motor development delay diagnosed at 6 months, one case of Duchenne muscular dystrophy diagnosed at 18 months and one case of autism spectrum disorder diagnosed at age 30 months) were found among the 16 borderline cases (18.75%). There was a significant difference in the prevalence of postnatal developmental disabilities between the normal and borderline KANET groups (P<0.001). Conclusion Our results suggest that the KANET assessment may be a useful diagnostic modality for the prediction of postnatal developmental disabilities.

Prenatal Diagnosis of Dextrocardia with Complex Congenital Heart Disease Using Fetal Intelligent Navigation Echocardiography (FINE) and a Literature Review.

Fetal dextrocardia is a type of cardiac malposition where the major axis from base to apex points to the right side. This condition is usually associated with a wide spectrum of complex cardiac defects. As a result, dextrocardia is conceptually difficult to understand and diagnose on prenatal ultrasound. The advantage of four-dimensional sonography with spatiotemporal image correlation (STIC) is that this modality can facilitate fetal cardiac examination. A novel method known as fetal intelligent navigation echocardiography (FINE) allows automatic generation of nine standard fetal echocardiography views in normal hearts by applying intelligent navigation technology to STIC volume datasets. In fetuses with congenital heart disease, FINE is also able to demonstrate abnormal cardiac anatomy and relationships when there is normal cardiac axis and position. However, this technology has never been applied to cases of cardiac malposition. We report herein for the first time, a case of fetal dextrocardia and situs solitus with complex congenital heart disease in which the FINE method was invaluable in diagnosing multiple abnormalities and defining complex anatomic relationships. We also review the literature on prenatal sonographic diagnosis of dextrocardia (with an emphasis on situs solitus), as well as tricuspid atresia with its associated cardiac features.

Is bladder neck and urethral mobility associated with urinary incontinence and mode of delivery 4 years after childbirth?

AIMS: To study changes in bladder neck, urethral mobility and urinary incontinence (UI) from pregnancy to 4 years postpartum and demonstrate any association to mode of delivery or presence of levator ani muscle (LAM) injury. Secondly, we aimed to correlate bladder neck and urethral mobility to UI symptoms. METHODS: Prospective study of 180 women, recruited in their first pregnancy and followed up 1 and/or 4 years postpartum. UI symptoms were assessed with a validated questionnaire. All underwent 4D transperineal ultrasound to assess LAM injury, bladder neck descent (BND), retrovesical angle at Valsalva (RVA), and urethral rotation between rest and Valsalva. A mixed model compared changes over time, different delivery modes, and women with and without LAM injury. Spearman's rank correlation tested the correlation of BND, RVA, and urethral rotation to UI symptoms. RESULTS: BND, RVA, and urethral rotation all increased following delivery. From 1 to 4 years postpartum, a larger increase in BND was found for women delivered vaginally with LAM injury, compared to women with intact LAM (P = 0.02) and women with cesarean section (P = 0.046). One year postpartum, BND and RVA correlated to UI symptoms, rs = 0.22, P = 0.01. Four years postpartum, RVA correlated to UI symptoms, rs = 0.19, P = 0.02. CONCLUSIONS: Although bladder neck and urethral mobility increased from pregnancy to 4 years postpartum irrespective of delivery mode, women with LAM injury had larger increase in BND, suggesting that this is important in the pathogenesis of bladder neck mobility and could lead to pelvic floor dysfunction in the long term.

Laparoscopic sacrocolpopexy: how low does the mesh go?

OBJECTIVE: Laparoscopic sacrocolpopexy is becoming an increasingly popular surgical approach for repair of apical vaginal prolapse. The aim of this study was to document the postoperative anterior mesh position after laparoscopic sacrocolpopexy and to investigate the relationship between mesh location and anterior compartment support. METHODS: This was an external audit of patients who underwent laparoscopic sacrocolpopexy for apical prolapse ≥ Stage 2 or advanced prolapse ≥ Stage 3, between January 2005 and June 2012. All patients were assessed with a standardized interview, clinical assessment using the International Continence Society Pelvic Organ Prolapse quantification and four-dimensional transperineal ultrasound to evaluate pelvic organ support and mesh location. Mesh position was assessed with respect to the symphysis pubis whilst distal mesh mobility was assessed using the formula √[(XValsalva - Xrest )2 + (YValsalva - Yrest )2 ], where X is the horizontal distance and Y is the vertical distance between the mesh and the inferior symphyseal margin, measured at rest and on Valsalva. RESULTS: Ninety-seven women were assessed at a mean follow-up of 3.01 (range, 0.13-6.87) years after laparoscopic sacrocolpopexy, 88% (85/97) of whom considered themselves to be cured or improved, and none had required reoperation. On clinical examination, prolapse recurrence in the apical compartment was not diagnosed in any patient; however, 60 (62%) had recurrence in the anterior compartment and 43 (44%) in the posterior compartment. On ultrasound examination, mesh was visualized in the anterior compartment in 60 patients. Both mesh position and mobility on Valsalva were significantly associated with recurrent cystocele on clinical and on ultrasound assessment (all P < 0.01). For every mm that the mesh was located further from the bladder neck on Valsalva, the likelihood of cystocele recurrence increased by 6-7%. CONCLUSION: At an average follow-up of 3 years, laparoscopic sacrocolpopexy was highly effective for apical support; however, cystocele recurrence was common despite an emphasis on anterior mesh extension. Prolapse recurrence seemed to be related to mesh position and mobility, suggesting that the lower the mesh is from the bladder neck, the lower the likelihood of anterior compartment prolapse recurrence.
