RESUMO
AIMS: Assess clinical utility of the foetal Myocardial Performance Index (MPI) in evaluation and management of monochorionic, diamniotic twin (MCDA) pregnancies. METHODS: Prospective cohort of (a) initially uncomplicated MCDA (b) Complicated MCDA, including twin-twin transfusion syndrome (TTTS), selective intrauterine growth restriction (sIUGR), and liquor and/or growth discordance (L/GD) not meeting TTTS or sIUGR criteria. TTTS and sIUGR were case-control matched. Routine Dopplers and MPI were taken and correlated to diagnosis and final outcome. RESULTS: Twenty-six always uncomplicated pairs, 51 always complicated pairs, and seven uncomplicated to pathological pairs were included. TTTS recipient (n = 25) left and right MPI and intertwin difference (ITD) were significantly elevated, however, were already elevated in Stage I (n = 10), and did not predict progression or pregnancy outcome. sIUGR MPI (n = 11) did not differ significantly from control. Of 15-L/GD pairs, two that progressed to TTTS had significantly higher left and right MPI values in the future recipient (0.61 and 0.72) versus future sIUGR larger twins (0.48 and 0.51) or stable L/GD (0.47 and 0.52): p < .01 for all comparisons. CONCLUSIONS: In this cohort, MPI did not add substantial diagnostic/prognostic information to current routine evaluation in established TTTS or sIUGR though potentially differentiated L/GD cases progressing to TTTS.

INTRODUCTION: To assess fetal vs. neonatal diagnoses, pregnancy outcomes and need for surgery in babies prenatally diagnosed with congenital pulmonary airway malformation (CPAM) or bronchopulmonary sequestration (BPS). METHODS: Retrospective single-centre cohort study of fetuses with a prenatal diagnosis of CPAM or BPS between 2006 and 2014. Data collected included serial antenatal ultrasound information and neonatal/infant diagnoses and outcomes. RESULTS: Initial ultrasound diagnosis (n = 63) was CPAM in 51 and BPS in 12: nineteen (30%) fetuses had mediastinal shift and 2 (3%) had hydrops. All neonates with known birth outcome (n = 56) were liveborn. Final diagnosis in 52 infants (83%) with neonatal imaging and/or histopathology confirmed CPAM in 17/44 (39%) and BPS in 6/9 (67%). Of 34 prenatally suspected but unconfirmed CPAM lesions: 10 had no lesion on neonatal imaging, one no neonatal imaging performed, five confirmed BPS, 11 other lung/thoracic lesions, seven were lost to follow-up. There was one infant death. 27/63 infants (43%) had post-natal surgery. More neonates requiring neonatal respiratory support/resuscitation had surgery compared to those who did not (67% vs. 29%, P = 0.008). Patients with suspected CPAM or BPS on both initial and final ultrasound were more likely to have post-natal surgical management than when a lesion was no longer visible on final antenatal ultrasound (68% vs. 23%, P = 0.001). CONCLUSIONS: Over 50% of antenatally suspected CPAM/BPS either regressed or had an alternate post-natal diagnosis. Perinatal outcome was good, with the majority of neonates/infants conservatively managed. Persistently visible antenatal lesion and need for neonatal respiratory support predicted ultimate surgical management.
RESUMO
BACKGROUND/AIMS: To examine the association between use of oral contraceptive pills (OCPs) and the risk of developing inflammatory bowel diseases (IBD), in a modern cohort. METHODS: A prospective nested case-control study across sites in the Asia-Pacific region was conducted; involving female IBD cases and asymptomatic controls. Subjects completed a questionnaire addressing questions related to OCP use. Primary outcome was the risk of development of IBD of those exposed to OCP versus non-exposure. Secondary outcomes were development of Crohn's disease (CD) versus ulcerative colitis (UC), and whether age of first use of OCP use may be associated with risk of IBD. RESULTS: Three hundred and forty-eight female IBD cases (41% CD, median age: 43 years) and 590 female age-matched controls were recruited. No significant association was found between OCP use and the risk of IBD (odds ratio [OR], 1.65; 95% confidence interval, 0.77-3.13; P=0.22), CD (OR, 1.55) or UC (OR, 1.01). The lack of association persisted when results were adjusted for age and smoking. IBD cases commenced OCP use at a younger age than controls (18 years vs. 20 years, P=0.049). CONCLUSIONS: In this large cohort of subjects from the Asia-Pacific region, we found a modest but not significantly increased risk of developing IBD amongst OCP users.
RESUMO
OBJECTIVES: To evaluate how fetal MRI is influencing current clinical practice and outcomes for central nervous system (CNS) anomalies in the Australian maternal-fetal medicine (MFM) setting. MATERIAL AND METHODS: Retrospective audit of cases January 2008-August 2013 referred for MFM ultrasound and MRI for suspected fetal CNS anomaly. Demographics, referral information, initial MFM diagnoses and investigations, MRI diagnoses, subsequent pregnancy management and perinatal outcome were examined. RESULTS: Fifty-seven women (41 singleton, 16 twin pregnancies) were seen at mean gestation of 23.7 ± 6.5 weeks. Major referral indications included ventriculomegaly (VM, 39%) and posterior fossa anomaly (PFA, 18%). MRI was performed at mean 27.2 ± 5.3 weeks. Diagnosis was altered from ultrasound in 31/57 cases (54%); 14 improving and 17 worsening prognosis. MRI findings worsening prognosis were more significant VM and PFA, agenesis of the corpus callosum, neuronal migration disorders and intraventricular haemorrhage. TOP or selective reduction occurred in 11 of 57 cases after full clinical workup (six where MRI worsened prognosis, five where MRI confirmed US poor prognosis). Mean gestation at birth was 37.2 ± 4.1 weeks for continuing pregnancies. There were nine cases of additional postnatal diagnoses, including four CNS anomalies. After neonatal workup, physical and/or developmental delay was anticipated for at least 14 of 43 (33%) infants. CONCLUSIONS: MRI added significant diagnostic information in about half the cases referred for workup of suspected CNS anomaly. In six of 17 cases where MRI worsened prognosis, TOP was chosen. Both additional CNS and non-CNS anomalies were diagnosed postnatally in 20%, emphasising the uncertain prognosis for, and evolution of, suspected CNS anomaly in fetuses.
