Aim: To examine the clinical utility of several prognostic factors for predicting preterm delivery. Methods: One hundred and nineteen patients with a singleton pregnancy admitted to our hospital because of symptoms of preterm labor were included in this study. Maternal serum C-reactive protein (CRP), transvaginal sonographic measurement of cervical length (CL), granulocyte elastase (EL) in cervical secretions, fetal fibronectin (fFN), alpha-fetoprotein (AFP), and insulin-like growth factor binding protein-1 (IGFBP-1) in vaginal secretions were examined on admission. EL, fFN, AFP, and IGFBP-1 were measured by bed-side test kits. Correlation between each factor and the duration of pregnancy (from admission to delivery) was investigated. Results: A significant correlation was found between the duration of pregnancy and CRP (r = -0.37, P < 0.001), but not CL. The duration was significantly shorter in the fFN-positive group than in the negative group (P = 0.0015). However, no significant difference was observed between the positive group and the negative group for each of CL, EL, AFP and IGFBP-1. Conclusion: Association between the duration of the pregnancy and two biochemical markers (CRP and fFN) was confirmed. As they can be examined quickly and easily, they are quite useful for estimating prognosis of preterm labor.
Although prenatal diagnosis of VACTERL (vertebral defects, anal atresia, cardiac anomaly, tracheal-esophageal fistula with esophageal atresia, renal defects, and radial limb dysplasia) association is not always possible, ultrasonography and magnetic resonance imaging can visualize some of the characteristic findings of this condition. Because infants with this condition usually require significant surgical treatment and care, prenatal detection with those imaging modalities should assist in proper planning for delivery and anticipated care of the neonate. In this report, we present dichorionic twin fetuses, both of whom were found postnatally to have this condition, and suggest the possible relationship between this disorder and intracytoplasmic sperm injection. As far as we know, this is the first report of twin fetuses affected by VACTERL association.
Long-term exposure to degenerating red blood cells is supposed to damage amnion, fetal alveolar epithelial cells and fetal pulmonary arteries, and may lead to dry lung syndrome and PPHN in the infant complicated by DCH.
Objective/Methods: Seckel syndrome is a rare form of primordial dwarfism and most of the previous reports have been limited to postnatal findings. We report on a fetus showing severe microcephaly, intrauterine growth restriction and a few gyri with shallow sulci on the fetal brain suggesting cortical dysplasia, followed by ultrasound and magnetic resonance imaging in the prenatal period. Results: Cardiotocograph revealed a reassuring fetal status throughout the whole pregnancy period. A male infant weighing 1,556 g was delivered at 39 weeks’ gestation, and a diagnosis of Seckel syndrome was made based on postnatal typical findings. Although previous reports on prenatal findings of Seckel syndrome are quite limited, we think that our case presents typical features of a fetus affected by this syndrome. Conclusions: When prenatal ultrasound shows severe microcephaly and intrauterine growth restriction, this rare syndrome should be included in the differential diagnosis. Moreover, magnetic resonance imaging of the affected fetal brain provides further diagnostic clues.
The purpose of this study was to examine the clinical features of pregnancy complicated by polyhydramnios associated with fetal anomalies. Sixty-nine patients with a singleton pregnancy complicated by polyhydramnios were retrospectively analyzed. Based on prenatal ultrasonographic findings, 13 cases were considered to have idiopathic polyhydramnios and the remaining 56 cases were associated with fetal anomalies. Between these two groups, no significant difference was found in the gestational weeks when polyhydramnios developed. However, significant difference was noted in the maximum amniotic fluid index (AFI) values during the pregnancy period; 25.4 +/- 2.7 cm in the former, and 30.6 +/- 8.9 cm in the latter (P = 0.0004). In all of 13 cases with idiopathic polyhydramnios, AFI values remained less than 30 cm until delivery. Twenty-two patients (39%) with fetal anomalies required a prenatal treatment such as amnioreduction and tocolysis, whereas only one patient (7.7%) with idiopathic polyhydramnios needed tocolysis therapy (P = 0.03). There was a significant risk of premature delivery with fetal anomalies (35.6 +/- 3.9 weeks' gestation vs. 38.8 +/- 1.5 weeks' gestation, P = 0.004) because of refractory polyhydramnios, rupture of membranes, non-reassuring fetal status, and intrauterine fetal death, and although most infants with idiopathic polyhydramnios were appropriate-for-dates, many of the infants with congenital anomalies were small-for-dates. Significant risk of fetal anomalies should be considered in pregnant women with severe polyhydramnios (AFI > or = 30 cm), an increased trend of amniotic fluid during the pregnancy period, polyhydramnios requiring a prenatal treatment, or fetal growth restriction. On the other hand, based on our experience, a fetus without these conditions seems to have a low risk of congenital anomalies even if polyhydramnios is noted.
