BackgroundGastroschisis is a congenital anomaly of the fetal abdominal wall, usually to the right side of umbilical insertion. It is often detected by routine antenatal ultrasound. Significant maternal and pediatric resources are utilised in the care of women and infants with gastroschisis. Increasing rates of gastroschisis worldwide have led institutions to review local data and investigate outcomes. A collaborative project was developed to review local epidemiology and investigate antenatal and neonatal factors influencing hospital length of stay (LOS) and total parental nutrition (TPN) in infants born with gastroschisis.MethodsWe performed a five-year review of infants born with gastroschisis (2011–2015) at a major Australian centre. Complex gastroschisis was defined as involvement of stenosis, atresia, ischemia, volvulus or perforation and closed or vanishing gastroschisis. We extracted data from files and databases at the two participating hospitals, a major maternal fetal medicine centre and the affiliated children’s hospital.ResultsThere were 56 infants antenatally diagnosed with gastroschisis with no terminations, one stillbirth (2%) and one infant with ‘vanishing’ gastroschisis. The mean maternal age was 23.9 years (range, 15–39 years). The mean gestation at delivery was 36 weeks (range, 25–39+ 3 weeks). Of the 55 neonates who received surgical management, 62% had primary closure. The median LOS was 33 (IQR, 23–45) days and the median duration of TPN was 26 (IQR, 17–36) days. Longer days on TPN (median 35 vs 16 days, P = 0.03) was associated with antenatal finding of multiple dilated bowel loops. Postnatal diagnosis of complex gastroschisis was made in 16% of cases and was associated with both longer LOS (median 89 vs 30 days, P = 0.003) and days on TPN (median 46 vs 21 days, P = 0.009).ConclusionComplex gastroschisis was associated with greater days on TPN and LOS. We found no late-gestation stillbirths and a low overall rate of 1.8%, suggesting the risk for stillbirth associated with gastroschisis is lower than previously documented. This information may assist counselling families. Improved data collection worldwide may reveal causative factors and enable antenatal outcome predictors.
Women from consanguineous relationships are at higher risk of adverse perinatal outcomes, including stillbirth. Given the 5% prevalence of consanguinity in our obstetric population, these findings have significant implications for preconception counselling, obstetric care and health resource allocation.
Background: Placenta accreta spectrum (PAS) has a high risk of maternal morbidity, and requires meticulous antenatal and peripartum management.Aims: To compare the management and outcomes of PAS between women with and without antenatally suspected disease, and to evaluate the effect of multidisciplinary team (MDT) management. Materials and methods: A retrospective cohort study identified all hysterectomy specimens with a histopathological diagnosis of PAS in the Western Sydney Local Health District between January 2006 and December 2019, and analysed each patient's clinical course.Results: Seventy patients had PAS diagnosed on hysterectomy specimens, of which 38 cases (54%) were antenatally suspected. Women with suspected PAS were more likely to have a previous caesarean section (100% vs 68%, P < 0.001), placenta praevia (92% vs 56%, P < 0.001) and anterior placenta (95% vs 66%. P = 0.011). Suspected PAS was associated with less maternal blood loss (median blood loss 2000 mL vs 4000 mL, P < 0.001), fewer red blood cell transfusions (median four units vs nine units, P < 0.001), and shorter intensive care or high dependency unit admission (mean stay one day vs three days, P = 0.037). There were no significant differences in other maternal morbidities. MDT management was associated with a clinically significant reduction in maternal blood loss (1500 mL vs 2520 mL, P = 0.09) and red blood cell transfusion (one unit vs six units, P = 0.04). The mean gestation of delivery was 37 weeks in both groups with no differences in neonatal morbidity. Conclusions:Both antenatally diagnosed PAS and MDT management reduced blood loss and blood transfusion. Elective delivery at 37 weeks gestation reduces the neonatal risks of preterm delivery.
BackgroundMicrophthalmia and anophthalmia are rare congenital fetal abnormalities. The combined incidence is estimated at 1 in 10,000 births. These two conditions arise from complex and incompletely understood genetic and/or environmental causes. Prenatal diagnosis is neither frequent nor easy and relies on precise, high-quality ultrasonography. Current antenatal ultrasound protocols for imaging of the fetal eye are inconsistent and inadequate to screen for the spectrum of ocular malformations, and there are no clear guidelines on detection of these rare abnormalities. Our study of two cases highlights the importance of early detection, and we review current practice and suggest a definitive fetal imaging protocol.Case presentationWe present two antenatal cases, one each of microphthalmia and anophthalmia, both diagnosed at the morphology scan at our tertiary fetal medicine unit. In both cases, the parents (a 36-year-old woman of Mauritanian ethnicity and a non-consanguineous partner of Nepalese descent, and a 31-year-old Caucasian woman and non-consanguineous Caucasian partner) elected to terminate their pregnancies and made unremarkable recoveries. Subsequent fetal autopsy confirmed the ultrasound scan findings.ConclusionsWe recommend that antenatal ultrasound guidelines are updated to specify use of a curvilinear transducer (2–9 MHz) to image both orbits in the axial and coronal planes, aided by use of a transvaginal probe when the transabdominal approach is inadequate to generate these images. When applicable, three-dimensional reverse-face imaging should be obtained to aid the diagnosis. The presence, absence, or non-visualization of lenses and hyaloid arteries should be documented in reports and these cases referred for a tertiary-level ultrasound scan and fetal medicine review. Imaging of the orbits should occur from 12 weeks’ gestation. Magnetic resonance imaging and amniocentesis with chromosome microarray testing may provide additional genetic and structural information that may affect the overall morbidity associated with a diagnosis of microphthalmia or anophthalmia.
Background On 9 June 2021, the Australian Technical Advisory Group on Immunisation and Royal Australian and New Zealand College of Obstetricians and Gynaecologists recommended that pregnant women receive Comirnaty (Pfizer) messenger RNA vaccine at any stage of pregnancy. Aim This multi‐centre study aimed to assess vaccine acceptance, reasons for hesitancy and determine if differences exist between health districts, to inform future policy strategies for COVID‐19 vaccination in pregnancy. Materials and methods An online survey (developed based on the World Health Organization Behavioural and Social Drivers survey and modified for the pregnant population) was administered to a sample population of pregnant women attending antenatal clinics at two metropolitan hospitals (Westmead and Royal North Shore Hospital (RNSH)) in New South Wales between 15 September 2021 and 22 October 2021. Results There were 287 pregnant women surveyed (Westmead 198 (69%), RNSH 66 (23%), no site 23 (8%)). There was a significantly lower Socio‐Economic Indexes for Areas score (5.66 vs 9.45, P = 0.001), fewer women born in Australia (37% vs 53%, P = 0.02) and higher number of children (0.77 vs 0.41, P = 0.01) among Westmead respondents. There was lower vaccination uptake (68% vs 86%, P = 0.01) and willingness to receive vaccine (68% vs 88% P = 0.01) at Westmead compared to RNSH. There was an increased proportion of respondents who were concerned that the vaccine could cause harm to the unborn baby at Westmead (38% vs 11%, P = 0.01). Conclusions Along with healthcare provider recommendation for vaccination in pregnancy, materials should be targeted to specific safety concerns of pregnant women.
The proportion of DS pregnancies diagnosed in the antenatal period in western Sydney could be increased by ensuring younger women are not falsely reassured that DS screening is unnecessary for them. While religious affiliation may be a factor when women decline screening, ensuring appropriate counselling remains important.
