RESUMO

BACKGROUND: The Society of Australia and New Zealand (SOMANZ) published its first sepsis in pregnancy and the postpartum period guideline in 2017 (Aust N Z J Obstet Gynaecol, 57, 2017, 540). In the intervening 6 years, maternal mortality from sepsis has remained static. AIMS: To update clinical practice with a review of the subsequent literature. In particular, to review the definition and screening tools for the diagnosis of sepsis. MATERIALS AND METHODS: A multi-disciplinary group of clinicians with experience in all aspects of the care of pregnant women analysed the clinical evidence according to the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system following searches of Cochrane, Medline and EMBASE. Where there were conflicting views, the authors reviewed the topic and came to a consensus. All authors reviewed the final position statement. RESULTS: This position statement has abandoned the use of the quick Sequential Organ Failure Assessment score (qSOFA) score to diagnose sepsis due to its poor performance in clinical practice. Whilst New Zealand has a national maternity observation chart, in Australia maternity early warning system charts and vital sign cut-offs differ between states. Rapid recognition, early antimicrobials and involvement of senior staff remain essential factors to improving outcomes. CONCLUSION: Ongoing research is required to discover and validate tools to recognize and diagnose sepsis in pregnancy. Australia should follow New Zealand and have a single national maternity early warning system observation chart.

RESUMO

INTRODUCTION: Hypertensive disorders of pregnancy (HDP) affect up to 10% of all pregnancies annually and are associated with an increased risk of maternal and fetal morbidity and mortality. This guideline represents an update of the Society of Obstetric Medicine of Australia and New Zealand (SOMANZ) guidelines for the management of hypertensive disorders of pregnancy 2014 and has been approved by the National Health and Medical Research Council (NHMRC) under section 14A of the National Health and Medical Research Council Act 1992. In approving the guideline recommendations, NHMRC considers that the guideline meets NHMRC's standard for clinical practice guidelines. MAIN RECOMMENDATIONS: A total of 39 recommendations on screening, preventing, diagnosing and managing HDP, especially preeclampsia, are presented in this guideline. Recommendations are presented as either evidence-based recommendations or practice points. Evidence-based recommendations are presented with the strength of recommendation and quality of evidence. Practice points were generated where there was inadequate evidence to develop specific recommendations and are based on the expertise of the working group. CHANGES IN MANAGEMENT RESULTING FROM THE GUIDELINE: This version of the SOMANZ guideline was developed in an academically robust and rigorous manner and includes recommendations on the use of combined first trimester screening to identify women at risk of developing preeclampsia, 14 pharmacological and two non-pharmacological preventive interventions, clinical use of angiogenic biomarkers and the long term care of women who experience HDP. The guideline also includes six multilingual patient infographics which can be accessed through the main website of the guideline. All measures were taken to ensure that this guideline is applicable and relevant to clinicians and multicultural women in regional and metropolitan settings in Australia and New Zealand.

RESUMO

Mowat-Wilson syndrome (MWS) is a complex genetic disorder associated with heterozygous variation in ZEB2. It is mainly characterized by moderate-to-severe intellectual disability, facial dysmorphism, epilepsy, and various malformations including Hirschsprung disease, corpus callosum anomalies, and congenital heart defects. It is rarely diagnosed prenatally and there is limited information available on the prenatal phenotype associated with MWS. Here we report the detection of a heterozygous de novo nonsense variant in ZEB2 by whole exome sequencing in a fetus with microphthalmia in addition to cardiac defects and typical MWS facial dysmorphism. As the prenatal phenotypic spectrum of MWS expands, the routine addition of fetal genomic testing particularly in the presence of multiple malformations will increase both the sensitivity and specificity of prenatal diagnostics.

RESUMO

Non-syndromic congenital hydrocephalus is aetiologically diverse and while a genetic cause is frequently suspected, it often cannot be confirmed. The most common genetic cause is L1CAM-related X-linked hydrocephalus and that explains only 5%-10% of all male cases. This underlines a current limitation in our understanding of the genetic burden of non-syndromic congenital hydrocephalus, especially for those cases with likely autosomal recessive inheritance. Additionally, the prognosis for most cases of severe congenital hydrocephalus is poor, with most of the surviving infants displaying significant intellectual impairment despite surgical intervention. It is for this reason that couples with an antenatal diagnosis of severe hydrocephalus are given the option, and may opt, for termination of the pregnancy. We present two families with CCDC88C-related recessive congenital hydrocephalus with children who had severe hydrocephalus. Those individuals who were shunted within the first few weeks of life, who did not require multiple surgical revisions, and who had a more distal truncating variant of the CCDC88C gene met their early childhood developmental milestones in some cases. This suggests that children with CCDC88C-related autosomal recessive hydrocephalus can have normal developmental outcomes under certain circumstances. We recommend CCDC88C analysis in cases of severe non-syndromic congenital hydrocephalus, especially when aqueduct stenosis with or without a medial diverticulum is seen, in order to aid prognosis discussion.

RESUMO

SOMANZ (Society of Obstetric Medicine Australia and New Zealand) has written a guideline to provide evidence-based guidance for the investigation and care of women with sepsis in pregnancy or the postpartum period. The guideline is evidence-based and incorporates recent changes in the definition of sepsis. The etiology, investigation and treatment of bacterial, viral and non-infective causes of sepsis are discussed. Obstetric considerations relevant to anaesthetic and intensive care treatment in sepsis are also addressed. A multi-disciplinary group of clinicians with experience in all aspects of the care of pregnant women have contributed to the development of the guidelines. This is an executive summary of the guidelines.

RESUMO

This guideline is an evidence based, practical clinical approach to the management of Hypertensive Disorders of Pregnancy. Since the previous SOMANZ guideline published in 2008, there has been significant international progress towards harmonisation of definitions in relation to both the diagnosis and management of preeclampsia and gestational hypertension. This reflects increasing knowledge of the pathophysiology of these conditions, as well as their clinical manifestations. In addition, the guideline includes the management of chronic hypertension in pregnancy, an approach to screening, advice regarding prevention of hypertensive disorders of pregnancy, and discussion of recurrence risks and long term risk to maternal health. The literature reviewed included the previous SOMANZ Hypertensive Disorders of Pregnancy guideline from 2008 and its reference list, plus all other published National and International Guidelines on this subject. Medline, Cochrane Database of Systematic Reviews (CDSR), Cochrane Central Registry of Controlled Trials (CCRCT), National Institute for Health and Care Excellence (NICE) Evidence Search, and Database of Abstracts and Reviews of Effects (DARE) were searched for literature published between January 2007 and March, 2014.

RESUMO

OBJECTIVES: This observational case-control study aims to test whether there is a relationship between maternal systemic hemodynamics, maternal renin-angiotensin system and fetal hemodynamics in normal and hypertensive pregnancy. STUDY DESIGN: Four groups of non-pregnant women (n=18), pregnant controls (n=25), women with gestational hypertension (n=21) and preeclampsia (n=10) were included. MAIN OUTCOME MEASURES: Maternal echocardiography parameters, plasma renin and aldosterone were correlated with fetal Doppler parameters in third trimester pregnancy. RESULTS: Higher maternal mean arterial pressure and total peripheral vascular resistance were associated with lower fetal middle cerebral artery pulsatility index (PI) (r=-.51, p<0.01 and r=-.49, p<0.01, respectively); mean arterial pressure correlated negatively with ductus venosus PI (r=-.35, p=0.01); higher maternal plasma aldosterone levels were associated with lower maternal uterine artery resistance (r=-0.33, p=0.03). CONCLUSIONS: It seems that maternal hemodynamics influence fetal hemodynamics with protective adaptation in fetal cerebral and ductus venosus blood flow observed as maternal blood pressure and vascular resistance increase.

RESUMO

A 28-year-old woman undertaking in vitro fertilisation had a single day five blastocyst transferred, resulting in a monozygotic triplet pregnancy. This case report illustrates the potential for multiple pregnancies even after transfer of a single embryo. A literature review regarding monozygotic triplets following use of assisted reproductive techniques reveals that an unexpectedly large proportion of these cases are associated with blastocyst transfer.

RESUMO

UNLABELLED: OBJECTIVE 1. To characterise the forearm vascular reactivity of women with pre-eclampsia in the third trimester of pregnancy and compare it with that in normal or gestational hypertensive pregnancies. 2. To document female sex steroid (oestradiol, progesterone, oestriol and betahCG) levels in the three groups of women. DESIGN: Forearm blood flow was measured by venous occlusion plethysmography during intra-arterial infusion of saline and vasoactive substances: angiotensin II, sodium nitroprusside, acetylcholine and N(G)-monomethyl-L-arginine (L-NMMA). SETTING: Research laboratory at St George Hospital, Kogarah, Sydney, Australia. SAMPLE: Fifteen non-pregnant women in the follicular phase of the menstrual cycle, 15 third trimester normal pregnant women, 13 women in the third trimester with gestational hypertension and 15 women with pre-eclampsia. MAIN OUTCOME MEASURES: Changes in forearm blood flow in response to vasoactive substances. RESULTS: Normal pregnant women had higher baseline forearm blood flow than non-pregnant women, decreased vasodilator responses to sodium nitroprusside and reduced vasoconstrictor responses to angiotensin II. No difference in response to angiotensin II, sodium nitroprusside or L-NMMA was found among normal pregnant, pre-eclampsia or gestational hypertension women, but vasodilatory responses of pre-eclamptic women to acetylcholine were reduced compared with normal pregnant women. Higher serum progesterone levels were found in women with pre-eclampsia and gestational hypertension than in normal pregnancy. CONCLUSION: The hyperdynamic circulation of normal pregnancy is characterised by refractoriness to angiotensin II but this is not altered in pre-eclampsia. Pre-eclamptic women demonstrate a reduced vasodilator response to acetylcholine which, in the absence of any alteration in response to L-NMMA, implies that factors other than nitric oxide deficiency mediate the vasoconstriction of pre-eclampsia.
