Obstetrical aspects in congenital ichtyosis

We present a case of congenital ichthyosis because obstetrical literature is scarce and most obstetricians could need a reminder and update. Congenital ichthyosis (CI) comprises a variety of skin disorders characterised by abnormal keratinization of the epidermis, which are mostly transmitted in an autosomal recessive manner. This condition is rare (seven per million people) with various clinical neonatal expressions and diversified prognosis, from self-healing to lethal. Even less severe phenotypes have significant associated morbidity and mortality. CI babies are often born prematurely and are at highest risk for complications during the postnatal period .CI, while fairly rare, is a condition well described in the literature, mainly from the neonatal point of view. We describe a case in which congenital ichthyosis was diagnosed after birth, and summarise the present literature with particular attention on obstetric implications as the prenatal diagnosis, genetic and ultrasound testing, perinatal complications and care for future pregnancies

Can the cerebroplacental ratio (CPR) predict intrapartum fetal compromise? : a prospective observational study

Objective: To investigate the potential clinical use of serial fetal CPR measurements during the last month of pregnancy for the prediction of adverse perinatal outcome in unselected low-risk pregnancies. Methods: A multicenter prospective observational cohort study in 315 consecutively recruited low-risk pregnancies. All eligible pregnancies underwent serial sonographic evaluation of fetal weight and Doppler indices at two week intervals, from 36 weeks gestation until delivery. Data were converted into centiles correcting for gestational age. These data were not available for the obstetrical team and hence, could not influence management decisions. Primary outcomes were operative delivery for presumed fetal compromise and a composite neonatal outcome (arterial cord Ph 90th centile). Results: Three hundred fifteen women were recruited in this study. We ecxluded 32 pregnancies because of small for gestational age babies (SGA), leaving 293 women and 583 CPR values for data-analysis. There were 85 (27%) adverse neonatal outcomes and 29 patients (9%) underwent operative delivery for presumed fetal compromise. Both primary and secondary outcomes were not significant different between the different CPR groups. Furthermore, we examined if individual serial CPR measurements could predict adverse outcome and found no linear correlation between repeated measurements of CPR and adverse outcomes. Conclusion: Our study shows that routine serial screening by CPR measurements provides poor prediction for adverse perinatal outcome in uncomplicated pregnancies

How an extended perinatal audit may improve perinatal policy

Objective: A perinatal audit has the intention of quality of care improvement based on analysis of perinatal death, with our without analysis of maternal morbidity and/or mortality. Additional analysis of cases of intrapartum asphyxia could provide more insight into ways to improve quality of perinatal care. Methods: Analysis of cases of perinatal death and asphyxia in Jan Yperman Hospital, Ieper, Belgium, in 2012. Results: Three perinatal deaths occurred, none were preventable. Nineteen cases of proven metabolic acidosis have been identified. Three cases are considered possibly preventable, four cases are considered preventable. In three (possibly) preventable cases, foetal monitoring was absent during the active second stage of labour. In two preventable cases, intervention following a significant ST event in the second stage of labour was delayed. In one case intervention was delayed in the first stage of labour, while in another, indicated operative delivery in the second stage was not conducted. Conclusions: Integrating intrapartum asphyxia in the perinatal audit gives an opportunity to identify and eliminate weak points in the perinatal care chain, thereby optimizing quality of care. Lessons learned from our internal audit are the value of foetal monitoring and adequate action on significant ST events during second stage of labour

Recurrent uterine artery pseudo-aneurysm requiring repeat embolization during pregnancy : a case report

Background: Uterine artery pseudo-aneurysms (UAP) mainly occur after traumatic delivery or traumatic pregnancy termination. A UAP can be either asymptomatic or present with symptoms such as vaginal bleeding, abdominal pain, hypovolemic shock, or fever when infected. We describe a patient diagnosed with a uterine artery pseudo-aneurysm in pregnancy that required repeat embolization. The patient had no risk factors in her recent medical history. She did, however, undergo in-vitro fertilization with oocyte retrieval performed under transvaginal ultrasonographic guidance. We suggest the hypothesis of formation of the pseudo-aneurysm secondary to vascular injury during oocyte retrieval. Case Report: A 35-year-old primigravida, who conceived by in-vitro fertilization, presenting with severe abdominal pain at 19 2/7 weeks of gestation. Ultrasound examination with color doppler imaging revealed a hypoechoic lesion with turbulent arterial flow pattern on the lower left side of the uterus. Selective catheterization and subtraction angiography permitted diagnosis of a large pseudo-aneurysm of the left uterine artery. A selective embolization was performed. Recanalization of the embolized artery was confirmed 11 weeks after initial presentation, requiring repeat embolization. A planned caesarean section was performed at 34 weeks of gestation and a healthy boy was born with a birth weight of 2065 g. Conclusion: Uterine artery pseudo-aneurysm is a rare but potentially life-threatening condition. It can be diagnosed using (doppler) ultrasound, revealing a hypoechoic mass with swirling blood flow. Angiography is the standard reference in diagnosing UAP and may provide definitive treatment. Management with selective unilateral uterine artery embolization appears to be safe in hemodynamically stable patients. It does not compromise uteroplacental circulation and may help to prolong the pregnancy, reducing morbidity associated with preterm birth

Antenatal corticosteroids-to-birth interval in preterm birth

Objectives: The purpose of this study was to compare short-term outcomes in children born between 24 and 34 weeks’ gestation, according to observed antenatal corticosteroids (ACS)-to-birth intervals. Research question: ‘Is there a difference in short-term outcomes between observed ACS-to-birth intervals across a range of gestational ages at birth?’ Methods: Cohort study assessing differences in incidence of short-term neonatal outcomes according to the observed interval between the last administration of ACS and birth. Linear, non-weighted GEE models with an independence working correlation structure were fitted to infant level data providing valid point estimates for either incidence or rate differences (binary outcomes) or average differences (continuous outcomes). Results: Of 886 children, 35.9% were born within 2 days after the last administration of ACS, 32.2% within 2 to 7 days, 14.1% within 8 to 14 days, and 17.8% more than 14 days after. Across gestational ages at birth, there were no differences in birth weight between children born at an ACS-to-birth interval of 7 days or less compared to more than 7 days, nor were there differences in respiratory outcomes, cerebral outcomes, or composite outcome. Conclusion: Drawing conclusions on the importance of the ACS-to-birth interval is difficult due to the post-hoc nature of the variable. In the absence of tools to better estimate if and when PTB will occur, it might not have any value in daily practice, regardless of whether there is an optimal ACS-to-birth interval or not

Obstetrical characteristics and neonatal outcome according to aetiology of preterm birth : a cohort study

Purpose Preterm birth (PTB) can be categorised according to aetiology into: spontaneous preterm labour (SPL), preterm prelabour rupture of membranes (PPROM), and iatrogenic (iatro) PTB. Outcomes could differ between these groups, which could be of interest in counselling. We aimed to explore differences between aetiologic groups of PTB in maternal demographics, obstetrical characteristics and management, and neonatal outcomes. Methods This is a cohort study (2012-2018) in Ghent University Hospital, Belgium, of deliveries from 24 + 0 to 33 + 6 weeks. We compared perinatal demographics, management, and outcomes between the aetiologic types of PTB. Point and interval estimates for differences between aetiologic types were estimated using a Generalised Estimating Equations approach to handle clustering due to multiple gestations. Results 813 mothers and 987 neonates were included. Prevalences of different aetiologic types of PTB were similar. Maternal BMI was higher in the iatrogenic group (iatro-SPL: + 1.92 kg/m(2), 95% CI 1.02, 2.83; iatro-PPROM: + 2.06 kg/m(2), 95% CI 1.15, 2.96). There was an inversed sex ratio (0.82, 95% CI 0.65, 1.03), more growth restriction (iatro-SPL: + 22.60%, 95% CI 17.08, 28.13; iatro-PPROM: + 24.64%, 95% CI 19.44, 29.83), and a higher caesarean section rate in the iatrogenic group (iatro-SPL: + 57.23%, 95% CI 50.32, 64.13, iatro-PPROM: + 56.79%, 95% CI 50.20, 63.38) and more patients received at least one complete course of antenatal corticosteroids (iatro-SPL: + 17.60%, 95% CI 10.60, 24.60, iatro-PPROM: + 10.73%, 95% CI 4.52, 16.94). In all types of PTB, adverse neonatal outcomes had a low prevalence, except for respiratory distress syndrome. A composite of adverse neonatal outcome was more prevalent in the SPL- compared to the PPROM group, and there was less intraventricular haemorrhage in the iatrogenic group. Conclusion Additional to gestational age at birth, the aetiology of PTB is associated with neonatal outcome. More data are needed to enable individualised management and counselling in case of threatened PTB
