RESUMO

INTRODUCTION: This trial evaluates whether daily low-dose aspirin initiated before 16 weeks of gestation can reduce preeclampsia and fetal growth restriction in nulliparous women identified by first-trimester uterine artery Dopplers as at high risk of preeclampsia. METHODS: This randomized, blinded, placebo-controlled, parallel-group trial took place in 17 French obstetric departments providing antenatal care. Pregnant nulliparous women aged ≥ 18 years with a singleton pregnancy at a gestational age < 16 weeks of gestation with a lowest pulsatility index ≥ 1.7 or a bilateral protodiastolic notching for both uterine arteries on an ultrasound performed between 11+0 and 13+6 weeks by a certified sonographer were randomized at a 1:1 ratio to 160 mg of low-dose aspirin or to placebo to be taken daily from inclusion to their 34th week of gestation. The main outcome was preeclampsia or a birthweight ≤ 5th percentile. Other outcomes included preeclampsia, severe preeclampsia, preterm preeclampsia, preterm delivery before 34 weeks, mode of delivery, type of anesthesia, birthweight ≤ 5th percentile and perinatal death. RESULTS: The trial was interrupted due to recruiting difficulties. Between June 2012 and June 2016, 1104 women were randomized, two withdrew consent, and two had terminations of pregnancies. Preeclampsia or a birthweight ≤ 5th percentile occurred in 88 (16.0%) women in the low-dose aspirin group and in 79 (14.4%) in the placebo group (proportion difference 1.6 [-2.6; 5.9] p = 0.45). The two groups did not differ significantly for the secondary outcomes. CONCLUSION: Low-dose aspirin was not associated with a lower rate of either preeclampsia or birthweight ≤ 5th percentile in women identified by their first-trimester uterine artery Doppler as at high risk of preeclampsia. TRIAL REGISTRATION: (NCT0172946).

RESUMO

OBJECTIVES: The aim of our study was to define the benefits and risks related to expectant management in the midtrimester rupture of membranes and to assess the prognostic factors in order to give objective informations to parents facing these obstetrical situations. STUDY DESIGN: We conducted a retrospective study. The study population included 49 patients with premature rupture of membranes at 16-23 weeks' gestation during the period January 1998-June 2003. The main criterion for judgement was neonate survival. Statistical analysis included chi2-test for the qualitative variables and Student's test for the quantitative variables. The threshold for significance was 5%. RESULTS: Twenty couples out of 49 chose medical termination of pregnancy. Among the 29 other pregnancies, the mean latency period was 2.1 weeks. The mean gestational age at delivery was 23.2 weeks. Nineteen patients were delivered after 22 weeks. The main prognostic factors were the initial amniotic fluid index (2.9 cm versus 0.8 cm) (p=0.042) and gestational age at delivery (26.7 weeks versus 22.6 weeks) (p<0.001). About 2% of the pregnancies were complicated by maternal infection. Eighty-three percent of the survivors had neonatal respiratory distress syndrome. 41.2% of them presented sepsis. We observed no cases of severe intraventricular haemorrhage. The number of infants born after 24 weeks of gestation and still alive at 1 week was 12, representing 24% of pregnancies and 63% of the infants born after 24 weeks. CONCLUSION: Expectant management can be widely suggested to patients. However, termination of pregnancy is acceptable, in cases with a poor prognosis including anamnios and premature rupture of membranes before 21 weeks.

RESUMO

OBJECTIVES: To evaluate the rate and circumstances of outborn deliveries within a French perinatal network, and to determine their avoidability. STUDY DESIGN: Cohort study including preterm infants <33 weeks gestation and/or weighing <1500g born outside a level III maternity unit in Lower Normandy region, France, in 2008-2010. In 2008 and 2009, only neonates transferred to the Caen University Teaching Hospital (CHU) were included. In 2010, all outborn neonates in the region were included by means of a medical information system program. A panel of 7 experts was set up to determine the avoidability of each outborn case using a two-stage modified Delphi procedure. Inter-expert agreement was evaluated using the kappa index. RESULTS: Sixty-four cases (71 neonates) were included. The outborn rate in 2010 was 16.1% (40/248, 95% CI (116-207%)). The most common reason for delivery was spontaneous onset of labour (57.8%). In 12 cases, the place of birth (level 2b maternity unit) was considered to be appropriate by the experts (term ≥32WG), but 8 cases involved infants of low birth weight (<1500g). For the 52 cases born in inappropriate sites, 9.6% were considered to be avoidable (kappa index=0.42 (p<10-3)). CONCLUSION: Our outborn rate meets regionalisation targets. Our method of expert evaluation identified a small percentage of avoidable births in inappropriate sites. Regular reassessment of obstetric practices and good coordination between network actors are crucial to improve the management of pregnancies at risk of outborn delivery.

RESUMO

We report a rare case of fibrosarcoma of the thigh suspected prenatally. At 27 weeks of gestation a voluminous, vascularised mass was discovered at ultrasound on the foetus' left leg, suggestive of haemangioma or a fibrosarcoma. There were no signs of heart failure. A rapid increase in the tumour mass was noted and a caesarean section was carried out at 39 weeks because of abnormal foetal heart rate. Postnatal ultrasound examination was comparable to that carried out prenatally; pathological examination of the mass biopsied and immunohistochemical investigation provided a diagnosis of congenital fibrosarcoma. After neoadjuvant chemotherapy and surgery the infant is now in complete remission without amputation.

RESUMO

PURPOSE: The objective of this study is to describe a prognostic classification for prenatally diagnosed sacrococcygeal teratoma (SCT). METHODS: Charts from 44 fetuses were reviewed. Three groups were defined as follows: group A--tumor diameter less than 10 cm, absent or mild vascularity and slow growth; group B--diameter 10 cm or greater, pronounced vascularity or high-output cardiac failure and fast growth; group C--diameter 10 cm or greater, predominantly cystic lesion with absent or mild vascularity and slow growth. RESULTS: Size at diagnosis, growth rate, and vascularity were higher in group B. Gestational age at delivery was lower in group B. Eleven of 21 died in the perinatal period in group B and none in groups A and C. In group C, drainage or shunting of the SCT has been performed in 6 of 10 cases. CONCLUSIONS: Group A is associated to good maternal and perinatal outcome, as well as group C, although shunting or drainage of the SCT could be necessary. Large fast-growing SCT with rich vascularity is associated with a higher perinatal mortality and morbidity than smaller lesions with mild vascularity.

RESUMO

Prenatal diagnosis of conjoined twins is rare. An accurate diagnosis is important to provide the parents the best information about the prognosis of the twins. We report a first-trimester diagnosis of an extremely rare type of conjoined twins using two-dimensional transvaginal ultrasound.
