    ABSTRACT: Objective Radiography after fetal or perinatal death has become a routine part of post mortem diagnostics. However, only a selected subset of these babygrams or fetal post mortem skeletal surveys (FPSS) provides useful information. We investigated the indication for an FPSS. Methods Inclusion consisted of the routinely made FPSS (2002-2012) in our university hospital in cases of fetal or perinatal death up to 7 days after birth. We categorized the diagnostic value of the FPSS as no, minor, major or pathognomonic. Regression analysis was used to determine the selection criteria for a useful FPSS. Results 337 FPSS were included. 305 (91%) showed no or minor skeletal malformations. 14 (4,2%) FPSS had major skeletal malformations. In 18 (5,3%) cases the diagnosis was based on the pathognomonic skeletal malformations on the FPSS. 2 cases were false positive after major birth trauma. The presence of multiple skeletal malformations on prenatal ultrasound or at post mortem external inspection was highly indicative of a diagnostic FPSS (p<0.001). Conclusion The majority of the babygrams / FPSS has no contribution to the diagnostic process. Multiple skeletal malformations on prenatal ultrasound or post mortem external inspection are indicative for a diagnostic FPSS, and this should be the main selection criterion.

    ABSTRACT: Objective: To validate the use of the integrative mid-trimester anomaly (IMTA) chart, a novel chart that aims to increase sonographers’ ability to diagnose fetal syndromes and complex anomalies. Methods: This study was conducted between September 2014 and January 2015. Pregnant women who attended our hospital for fetal medicine consultation during the second trimester were recruited. The diagnosis was assigned by a qualified consultant. The research coordinator randomized women between two groups (each consisted of two sonographers with comparable experience) and each was then examined twice (once with and once without the chart). Supposed diagnosis, patient and sonographer satisfactions were reported. Results: Twenty five women were recruited. Their average age was 26.48 ± 4.49 years and gestational age at examination was 24.39 ± 6.39. There were 17 (68%) fetuses that had multiple anomalies. The duration of examination was comparable. However, patient and sonographer satisfactions were higher when the same women were examined with the chart (p < 0.0001). The accuracy of diagnosis was also significantly higher (p = 0.03). Conclusion: The IMTA chart seems to be a useful tool for novice sonographers that could increase their diagnostic accuracy and improve their patient and their own satisfaction.

    ABSTRACT: Abstract Aim: The potential benefits and safety of early oral feeding (EOF) after cesarean section have not been well evaluated. We undertook a meta-analysis to assess postoperative bowel function and complications following EOF compared with delayed oral feeding (DOF) in women who had undergone cesarean section. Methods: PubMed, EMBASE, and CENTRAL were searched to identify English language randomized clinical trials comparing EOF with DOF after cesarean section. The primary outcomes of interest were bowel motility and postoperative complications. The random-effect model was used to calculate pooled weighted mean differences (WMDs) and relative risks (RRs), with 95% confidence intervals (CIs). Results: Eleven studies involving 1800 patients were included. The pooled results showed that EOF was significantly associated with the shorter time to return of bowel motility compared with DOF (-7.3 h for passage of flatus; -6.27 h for bowel movement; -8.75 h for bowel sounds). EOF was not related to increases in nausea (RR, 0.95; 95% CI, 0.69-1.33), abdominal distension (RR, 0.68; 95% CI, 0.43-1.07), diarrhea (RR, 0.63; 95% CI, 0.28-1.41), mild ileus symptoms (RR, 0.82; 95% CI, 0.53-1.25) and vomiting (RR, 0.91; 95% CI, 0.53-1.56). Conclusions: This meta-analysis provides evidence that EOF after cesarean section enhances the return of bowel function and does not increase the risk of postoperative complications.

    ABSTRACT: Abstract Objective: To evaluate the pregnancy outcomes of all patients who underwent electrosurgical cone biopsy of the cervix between January 2000 and December 2011 and subsequently became pregnant. Study design: Retrospective cohort study. Settings: District General Hospital in the North East of England. Methods: Patients were identified from the local colposcopy electronic data, Hospital Episode Statistics and Maternity electronic data. Data were collected on a pro forma with two sections: (1) treatment section and (2) pregnancy section. In the treatment section, year and indication for treatment, volume of cervix removed, histological results and marginal status of specimen were documented. In the pregnancy section, time interval between treatment and pregnancy, pre-treatment obstetric history, cervical length measurements, cervical suture, gestation and mode of delivery and neonatal outcome were documented. Data were analysed using SPSS. Results: 25 women achieved 47 pregnancies after electrosurgical cone biopsy treatment. Most common indication for cone biopsy was glandular neoplasia accounting for nearly half of the procedures; 21.2% of pregnancies ended in first-trimester miscarriages. The preterm delivery rate (<37 weeks) was 19.4%. Volume of cervix excised was significantly greater in women who delivered preterm compared to women who delivered at term (p = 0.028). The rate of preterm delivery was significantly higher in post treatment pregnancies when compared to pregnancies before treatment in the same women (p = 0.02). The preterm delivery in post-treatment pregnancies was not related to the time interval between treatment and pregnancy (p = 0.54). There was no significant difference in miscarriage rates in pre- and post-treatment pregnancies (p = 0.98). Conclusion: Electrosurgical cone biopsy of cervix is associated with increased risk of preterm labour that is related to the volume of cervix excised.

    ABSTRACT: Abstract Objective: To investigate the role of matrix metalloproteinases (MMP-2, MMP-9) and their inducer (CD147) in premature rupture of membranes (PROM) at term labor. Methods: In a cross-sectional study, 24 women aged 19-39, with 37-40-week pregnancy, and no clinical and histological signs of chorioamnionitis, were divided into two groups with and without PROM. The histological and immunohistochemical study of the fetal membranes was performed with polyclonal rabbit antibodies to MMP-2/MMP-9 and monoclonal rabbit antibodies to CD147. Results: The analysis of MMP revealed the increase of MMP-9 expression in the amniotic epithelium during premature membrane rupture both in rupture area, and beyond it, and increased MMR-2 expression in the mesodermal cells. We also found high level of CD147 in the amniotic epithelium in PROM group. The above-mentioned changes were found in all areas of fetal membranes, regardless of the rupture localization. Conclusions: The study results demonstrate the increased expression of MMR-2 and MMR-9, which regulate the catabolism of fetal membrane extracellular matrix proteins, in amniotic membranes of women with PROM at term labor. The increased expression of CD147 may be one of the mechanisms triggering PROM in the absence of infection.

    ABSTRACT: Abstract Objective: To analyze the course of maternal diseases and compare pregnancy outcomes in patients with systemic lupus erythematosus (SLE)-associated thrombocytopenia to patients without. Methods: Medical charts of 77 pregnancies in 73 SLE patients were systematically reviewed. Patients were divided into two groups according to the presence or absence of thrombocytopenia. Patients who are new onset SLE during pregnancy were also been studied. Result: Thrombocytopenia was found in 18 (23.3%) of the pregnancies. SLE patients with thrombocytopenia during pregnancy had higher percentage of disease flaring (11/18 versus 14/59, p = 0.003) and SLE-Pregnancy Disease Activity Index (7.89 ± 6.192 versus 2.41 ± 3.3.89, p = 0.001) compared to patients without. Also, patients with thrombocytopenia had a higher percentage of pulmonary, cardiac and multiple organ system involvement. There was a statistically significant difference in preeclampsia and early onset hypertensive disorder induced before 34 weeks as well as the rate of live birth less than 34 weeks (33.3% versus 6.8%, p = 0.003 & 38.9% versus 13.6%, p = 0.018 & 16.7% versus 1.7%, p = 0.038). Patients with thrombocytopenia suffered from higher rate of pregnancy loss (22.2% versus 3.4%, p = 0.024) and neonatal death (33.3% versus 1.7%, p = 0.000). In our study there were 17 patients with new-onset of SLE during pregnancy. The hematological system manifestation occurred in all of them and there was a significant increase in the incidence of thrombocytopenia (n = 12, 70.6%). Conclusion: Thrombocytopenia in SLE during pregnancy indicates higher disease activity, severe organ damage, early onset preeclampsia and higher pregnancy loss.

    ABSTRACT: Abstract Objective: The purpose of this retrospective observational cohort study was to determine the impact of certain risk factors on fetal loss, after mid-trimester amniocentesis. Material and methods: Six thousand seven-hundred and fifty-two (6752) consecutive amniocenteses with known pregnancy outcome performed during a 7-year period (2004-2010) were included in this study. Different maternal-, fetal- and procedure-related factors were evaluated in this study. Results: During this 7-year period, 6752 cases who underwent amniocentesis, with complete data available were evaluated for the outcome and risk factors mentioned. Total fetal loss rate (FLR) up to the 24th week was 1.19%. Risk factors associated with increased risk of fetal loss after amniocentesis were maternal age (OR:2.0), vaginal spotting (OR:2.2) and serious bleeding (OR:3.5) during pregnancy, history of 2nd trimester termination of pregnancy (OR:4.0), history of more than three spontaneous (OR:3.0) or surgical first trimester abortions (OR:2.1), fibromas (OR:3.0) and stained amniotic fluid (OR:6.1). Conclusions: Amniocentesis is a safe-invasive procedure for prenatal diagnosis with total FLR of 1.19% in our institution during the study period. The present study has emphasized the significance of certain risk factors for adverse outcome and therefore the need to individualize the risk.

    ABSTRACT: Abstract Objective: We investigated the impact of antenatal diagnosis of fetal growth restriction (FGR) on the risks of mortality and morbidity for very preterm infants given actual birthweight percentiles. Methods: Data on 4608 live born infants 24-31 weeks of gestational age (GA) in 10 European regions in 2003 were used to compare in-hospital mortality, bronchopulmonary dysplasia (BPD) and severe neurological morbidity by birthweight percentiles and antenatal diagnosis of FGR. Other covariates were GA, sex, multiplicity, maternal complications, antenatal corticosteroids, birth in a level III center and region. Results: Sixteen percent (n = 728) of all infants and 72%, 30% and 6%, respectively, of those with birthweight percentiles <10th, 10th-24th and ≥25th had an antenatal diagnosis of FGR. After adjustment for clinical factors, antenatal diagnosis of FGR was not associated with mortality for infants with a birthweight ≥10th percentile (OR [95% CI]: 0.9 [0.5-1.9] and 1.0 [0.6-1.8] for birthweights between the 10th-24th percentile and ≥25th percentile, respectively), but infants with a birthweight <10th percentile had higher mortality (OR [95% CI]: 2.4 [1.0-5.8]). No association was observed at any birthweight percentile with BPD or severe neurological morbidity. Conclusion: Antenatal diagnosis of FGR did not influence risks of mortality or morbidity when birthweight was ≥10th percentile; however, mortality risk was higher in antenatally detected infants with birthweight below the <10th percentile.

    ABSTRACT: Abstract Objective: To determine the relationships between gastroesophageal reflux (GER) and both respiratory inhibition after crying (RIAC) and feeding hypoxemia in infants. Methods: We screened for RIAC and feeding hypoxemia among infants with a gestational age of 36 weeks or greater using pulse oximetry. We investigated the infants who showed hypoxemia with a decrease in SpO2 to less than 70% and bradycardia with a heart rate of less than 100 beats per minute caused by GER. We then evaluated the relationships between these events and both RIAC and feeding hypoxemia. Results: We examined 250 infants in the present study. RIAC and feeding hypoxemia were observed in 35 (14.0%), and 30 (12.0%) infants, respectively. Ten infants showed hypoxemia and bradycardia caused by GER. These events were correlated with RIAC (p = 0.006) and feeding hypoxemia (p = 0.031). Conclusions: In the infants with RIAC and feeding hypoxemia, some show severe hypoxemia and bradycardia caused by GER. Medical staff caring for infants should note the presence of RIAC and feeding hypoxemia.

    ABSTRACT: Abstract Objective: The aim of this study was to evaluate postnatal outcomes in fetuses with gastroschisis. Methods: This is a retrospective study (2009-2013) of patients with gastroschisis at the Hospital São Paulo (Federal University of São Paulo, Brazil). Results: A total of 44 infants with gastroschisis were examined. The mean maternal age was 21.1 years and mean gestational age at delivery was 36.1 weeks. Delivery occurred before 34 weeks in 13.6%, between 34 and 36 weeks and 6 d in 40.9%, and after 37 weeks in 45.5%. The mean birth weight was 2349 g, with 37.2% small-for-gestational age infants. The mean umbilical cord blood pH was 7.32. Bowel resection and delayed fascial closure was performed in 14.6% and 19.5%, respectively. The mean hospitalization time in the neonatal intensive care unit was 52.7 d. Neonatal infection was detected in 52.4%, with a positive blood culture; 77.3% of those cases were coagulase negative staphylococci. The overall rate of mortality was 25%; 18.2% before birth, 45.4% during the neonatal period, and 36.4% in infants. The main cause of postnatal death was septicemia (55.5%). Conclusions: Despite advances in perinatal care and surgical techniques, infants with gastroschisis still present high rates of complications and death.

    ABSTRACT: Abstract Objective: This study was aimed at evaluating differences in breastfeeding initiation rates by maternal place of birth among women giving birth in one of 14 hospitals in Lazio, Italy, between 2006 and 2011. Methods: The data on 14 hospitals for this study were taken from a survey on healthy newborns carried out during the month of October each year. It collected information on maternal characteristics and infant feeding during the hospital stay. The exposure variable was maternal place of birth. The outcome variable was infant feeding during hospital stay classified as exclusive breastfeeding, predominant breastfeeding (PBF), complementary feeding or formula feeding. Both a descriptive analysis and a logistic regression on infant feeding (exclusive/PBF versus partial or non-breastfeeding) by maternal place of birth were carried out. The logistic regression model was adjusted for confounding factors. A random effect model was used to take into account the correlation of data among the hospitals. Results: Among the 6505 mothers included in this study, 18.7% were born in non-industrialized countries. Overall, 64.9% of mothers exclusively breastfed their babies, with lower prevalence among Asiatic mothers. The logistic model confirmed that breastfeeding was lower among infants born to Asian mothers (OR: 0.52; 95% CI: 0.35-0.77) compared with other groups, taking into account the effect of the other variables included in this model. Intracluster correlation was equal to 26%, showing that the hospital's model of care is a strong predictor of the initiation of breastfeeding. Conclusions: These data are useful for targeting disadvantaged groups when promoting breastfeeding.
