Prenatal diagnosis of cystic hygroma cases in a tertiary centre and retrospective analysis of pregnancy results.

The aim of this study is to retrospectively examine invasive diagnostic methods, structural anomalies accompanying cystic hygroma, and pregnancy outcomes in cystic hygroma cases admitted to a tertiary centre. The population of the study consisted of 29 live foetuses with cystic hygroma in the foetal neck only in the first or second trimester. In the study, pregnant women who applied to our centre were included. Amniocentesis or chorionic villus sampling was performed for genetic analysis according to the weeks of the pregnant women who were diagnosed with cystic hygroma by ultrasound examination by two clinicians experienced in foetal anomaly. Of the pregnant women included in the study, 10 had normal karyotype, 12 had abnormal karyotype and 13 had structural abnormality. It is very important to provide genetic counselling to the families of foetuses with cystic hygroma with a multidisciplinary team approach consisting of neonatologists, paediatric surgeons and experienced sonographers. Implications for rehabilitationWhat is already known on this subject? Cystic hygroma, also known as cystic lymphangioma, is a congenital cystic malformation often seen in the first trimester, which occurs in the foetal neck due to the failure of the connections between the cervical lymphatic vessels and the jugular venous system to develop normally. Cystic hygroma may be isolated, but highly associated with foetal aneuploidy, hydrops fetalis, abnormal foetal nuchal translucency.What do the results of this study add? Invasive prenatal diagnostic tests (CVS or amniocentesis) should be performed in all patients with cystic hygroma, as cystic hygromas can be diagnosed by first trimester foetal genetic sonogram screening and are largely accompanied by chromosomal abnormalities.What are the implications of these findings for clinical practice and/or further research? In foetuses with cystic hygroma, foetal karyotyping, detailed sonography and their documentation, genetic counselling is important to families of cystic hygroma foetuses with a multidisciplinary team approach consisting of neonatologists, paediatric surgeons and maternal foetal medicine specialists, since there is a high risk for aneuploidy and foetal malformation.

Diagnosis of central nervous system abnormalities: comparison of prenatal neurosonography and foetal magnetic resonance imaging findings.

Magnetic resonance imagining (MRI) is gradually becoming the more preferred imaging modality in the evaluation of central nervous system (CNS) abnormalities rather than foetal ultrasonography (USG). The aim of this study was to compare the findings of prenatal neurosonography and foetal MRI. The study was a retrospective study analysing the records of 160 pregnant women who underwent both foetal MRI and USG due to suspicion of CNS abnormalities between 2008 and 2019. Indications for applying foetal MRI were neurosonography and foetal MRI findings. When the compatibility between MRI and USG results was examined in CNS abnormalities, it was found fully compatible in 61.3% of cases, partially compatible in 24.53% of cases, and not compatible in 14.5% of cases. When comparing prenatal neurosonography and foetal MRI findings, additional findings were reported in 16.9% of cases, and no additional finding was reported in 66.8% of cases. While normal anatomical findings were reported in 8.8% of the cases in MRI, the diagnosis made by neurosonography changed in 7.5%. Foetal MRI has more advantages than USG both in imaging the CNS abnormalities in more detail and in determining the accompanying additional anomalies.IMPACT STATEMENTWhat is already known on this subject: USG is a safe, practical and cost-effective primary imaging method that is widely used for foetal anomaly screening. However, there may sometimes be difficulties in evaluating the foetal brain structures due to foetal position which is unsuitable for imaging, extremely obese with a high body mass index, oligohydramnios and ossified foetal skull. For this reason, magnetic resonance imaging (MRI) is used as the most commonly used imaging method after USG in the evaluation of foetal anatomy, especially CNS.What do the results of this study add?: In our study, we saw that foetal MRI has more advantages than neurosonography in both seeing CNS abnormalities in more detail and recognising additional anomalies that may accompany.What are the implications of these findings for clinical practice and/or further research?: We have seen that besides neurosonography, foetal MRI can provide important information that can affect the clinical approach in pregnancy management by increasing the correct diagnosis in pregnancies with congenital CNS abnormalities. MRI: it is the best secondary imaging modality that can aid diagnosis in addition to neurosonography in the diagnosis of CNS abnormalities and in suspected cases. Therefore, foetal MRI should be used more widely in prenatal diagnosis.

Association between early oxidative DNA damage and iron status in women with gestational diabetes mellitus.

This study aims to assess the relationship between oxidative DNA damage and iron status in women with gestational diabetes mellitus (GDM) compared to those with normal glucose tolerance in the first and the second trimesters of pregnancy. Maternal serum and urine samples were collected in the 11th-14th weeks and the 24th-28th weeks of gestation. In addition to oral glucose tolerance test in the second trimester, fasting blood glucose, HbA1c, ferritin and hemoglobin levels were measured in blood samples. Urinary levels of oxidative DNA damage products 8-hydroxy-2'-deoxyguanosine (8-OH-dG) and 8,5'-cyclo-2'-deoxyadenosines (S-cdA, R-cdA) were determined using liquid chromatography-tandem mass spectrometry with isotope-dilution. In the first trimester, urinary 8-OH-dG levels were found higher in the GDM group (n = 33) than in the control group (n = 84) (p = 0.006). R-cdA and S-cdA levels were not significantly different between the two groups (p = 0.794 and p = 0.792 respectively). When the cases were stratified according to their first trimester ferritin levels, women with ≥50th centile (≥130 ng/mL) demonstrated higher levels of 8-OH-dG and R-cdA than those under <50th centile (p = 0.034, p = 0.009). In the GDM group, there was a positive correlation between the second trimester 8-OH-dG and ferritin and 1st-hour glucose levels (p = 0.014, p = 0.020). This is the first study where oxidative DNA damage is evaluated in both early and late periods of pregnancy. Our findings reveal an association between GDM and iron status and oxidative DNA damage.

The effects of pre-pregnancy obesity and gestational weight gain on maternal lipid profiles, fatty acids and insulin resistance.

OBJECTIVES: Pregnancy is associated with physiological alterations in insulin sensitivity and lipid metabolism. This study investigates the associations between pregestational body mass index (pBMI) and the rate of gestational weight gain (rGWG) in the second trimester with the biomarkers of lipid, fatty acids metabolism and insulin resistance. METHODS: Sixty nine pregnant women followed. The body weights of the pregnant women were measured and blood samples were obtained at 11-14th and 24-28th weeks of pregnancy. Glucose, total cholesterol, triglyceride, HDL cholesterol, LDL cholesterol, insulin levels and fatty acids were measured. Rate of GWG (kg/week) and The Homeostasis Model Assessment for Insulin Resistance (HOMA-IR) were calculated. The pregnant women were stratified according to their pBMI and the 2nd trimester rGWG. RESULTS: The rate of GWG was significantly higher for the group with pBMI<25, compared to the group with pBMI≥25 (p=0.024). Triglyceride, total cholesterol, LDL and HDL cholesterol were significantly increased in the second trimester compared with the first trimester. Palmitic acid, oleic acid, linoleic acid, myristic acid, docosahexaenoic acid (DHA), arachidonic acid (AA), total omega-6 (n - 6) and omega-3 (n - 3) fatty acid levels and n - 6/n - 3 ratio were significantly higher in the second trimester. Glucose was significantly decreased and insulin was increased in the second trimester. In the overweight/obese group; HOMA-IR, insulin, AA, palmitoleic acid and stearic acid were found to be high in comparison to the group with low/normal pBMI. No parameters were associated with rGWG. CONCLUSIONS: The changes in lipid parameters, free fatty acids, insulin and HOMA-IR in the second trimester were compatible with the changes in lipid metabolism and the development of insulin resistance. Pregestational BMI was shown to have a stronger influence on lipid profile, insulin resistance, and fatty acids than rGWG.

Effect of vascular endothelial growth factor on fetal vessels among obese pregnant women.

OBJECTIVE: To determine the role of vascular endothelial growth factor (VEGF) in placental hypoperfusion in obesity. METHODS: The prospective study enrolled women with a first-trimester singleton pregnancy in Izmir, Turkey, between January and April 2011. Participants were divided into three groups: obese (body mass index [BMI, calculated as weight in kilograms divided by the square of height in meters] >30) with cesarean delivery; normal weight (BMI <30) with vaginal delivery (NVD); and healthy controls (BMI <30) with cesarean delivery. Before delivery, serum C-reactive protein (CRP), and uterine and fetal Doppler measurements were taken. VEGF was evaluated immunohistochemically from the umbilical cord. RESULTS: Overall, 109 women completed the study: obesity group (n=13, 11.9%), NVD group (n=50, 45.9%), and control group (n=46, 42.2%). Serum CRP was higher in the obesity group than in the control or NVD groups (P=0.009). VEGF score was highest in the NVD group (9.39 ± 3.11), and lowest in the obesity group (4.58 ± 2.78) (P<0.001). VEGF score decreased by 0.81 for each increase in BMI of 1 (P=0.002). CONCLUSIONS: Maternal obesity was related to decreased VEGF expression. Although not supported by Doppler findings, decreased VEGF expression owing to maternal obesity might trigger endothelial dysfunction and inflammation.

First-trimester placental function in levothyroxine-using pregnant women: a case-control study.

We aimed to compare the pregnancy-associated plasma protein-A (PAPP-A) and the uterine artery pulsatility index (UtA PI) levels of euthyroid pregnant women using levothyroxine vs. a control group of uncomplicated pregnancies and to evaluate the effects of different levothyroxine dosages on pregnancy outcomes. We retrospectively evaluated 206 levothyroxine-using pregnant women by looking at their basic placental function markers and obstetric outcomes. A sample of 449 women whose pregnancies concluded with uncomplicated term deliveries composed of our control group. To examine the relationship between the levothyroxine dosages and the frequency of pregnancy complications, levothyroxine users were divided into different groups according to the 75, 100, and 150 mcg cutoffs. The median PAPP-A MoM levels of levothyroxine users were significantly lower at 0.94 vs. 1.11 (p < .001) and the median mean UtA PI was significantly higher than the control group at 2.08 vs. 1.74 (p < .0001). The median birth weight was significantly lower for the levothyroxine users' group at 3292 g vs. 3427 g (p < .0001). Using 75, 100, and 150 mcg dose cutoffs, PAPP-A MoM, mean UtA PI and obstetric complication frequencies were not significantly different among levothyroxine users. Significant changes in placental function markers have been observed in euthyroid levothyroxine-using pregnant women during the first trimester. However, the frequency of obstetric complications does not appear to be dose dependent.

Prediction of ischemic placental diseases during the first trimester combined test period: a retrospective cohort of low-risk pregnancies in search of the link between parity and disease.

Objective: To assess the predictive power of a multifactorial model established on maternal characteristics, placenta-associated plasma protein A (PAPPA), and the mean uterine artery pulsatility index (Ut A PI) levels for the development of ischemic placental diseases (IPD) during the first-trimester combined test (FTCT) period and to evaluate the strength of some generally accepted clinical risk factors.Method: The studied data were obtained from a retrospective cohort of low-risk singleton pregnancies in the FTCT between 1 August 2016 and 1 December 2017. After routine 11-13-week examinations for FTCT, the Ut A PI was measured and stored electronically. The PAPPA multiple of median (MoM) was obtained as a routine component of aneuploidy screening.Results: A sample of 2493 pregnancies with clearly documented outcomes was studied. Early-onset preeclampsia, late-onset preeclampsia and fetal growth restriction (FGR) were observed in 9 (0.36%), 27 (1.08%), and 41 (1.64%) cases, respectively. With optimum cut-off levels of 0.69 for PAPPA MoM and 2.05 for mean Ut A PI and a false positive rate of 4.9%, IPD cases could be predicted with 83.3% sensitivity and 73.7% specificity. Nulliparity, previous abortion in nulliparous women and first pregnancy from second marriage were not independent risk factors. Maternal age, an interval from the last delivery longer than 6 years, and body mass index were found to be independent risk factors.Conclusion: The IPD showed some common and distinct clinical, laboratory and Doppler findings during the FTCT and were predictable with the help of multifactorial analysis. Some widely accepted risk factors could be affected by various confounders. Because of the increased IPD frequencies, parous women with a time interval from the last delivery of 6 years or longer should be screened as a high-risk group for placental dysfunction-related diseases.

A prospective cohort study on the prediction of the diagnosis-to-delivery time in preeclamptic pregnancies: should the sFlt-1/PlGF ratio be added to routine evaluations?

PURPOSE: To analyze the clinical and laboratory factors that potentially affect the diagnosis-to-delivery time in preeclamptic pregnancies. METHODS: In this cross-sectional study, we followed 24 early onset preeclampsia (E-PE) and 26 late-onset preeclampsia (L-PE) cases. Maternal serum samples were obtained at the time of diagnosis and stored at - 80 °C until ELISA analysis for soluble fms-like tyrosine kinase-1 (SFlt-1) and placental growth factor (PlGF) levels. RESULTS: The median follow-up duration was 68 (1-339) h in the E-PE group and 330 (7-1344) h in the L-PE group. Maternal mean arterial pressure (MAP) at hospitalization was the strongest variable, and the sFlt-1/PlGF ratio added significantly to the Cox regression model. In the E-PE cases, the median sFlt-1/PlGF ratio was significantly higher in the subgroup with a follow-up duration > 48 h than in the subgroup of cases with a follow-up duration ≤ 48 h (5109 vs. 2080; p = 0.038), and none of the seven cases with an sFlt-1/PlGF ratio ≥ 75th percentile delivered during the first 48 h. Neither the 24-h proteinuria nor the gestational age at diagnosis added to the predictive power of the MAP at hospitalization. CONCLUSION: Incorporation of the sFlt-1/PlGF ratio to the routine evaluation of preeclamptic pregnancies may help in the prediction of progression and management planning.

A prospective study on fetal posterior cranial fossa assessment for early detection of open spina bifida at 11-13 weeks.

The objective of this study was to test three measurements: brain stem (BS), intracranial translucency (IT) and brain stem to occipital bone distance (BSOB), as well as one landmark: cisterna magna (CM) visibility, for early diagnosis of open spina bifida (OSB) in a low risk population. A prospective observational study was undertaken in a university hospital. A sample of 1479 women consented to participate between 20 September 2013 and 30 June 2015. Measurements were performed from the mid-sagittal view, as is routinely used for nuchal thickness assessment. CM visibility was assessed qualitatively as the third anechoic band in the posterior cranial fossa (PCF). All pregnancies were screened with a combination of maternal serum alpha-fetoprotein and second trimester anomaly scan and followed until delivery. Predictive values were calculated for each marker. We were able to diagnose two OSB cases and highly suspect one Dandy-Walker malformation case at the first trimester scan by the observation of PCF. PCF characteristics of OSB cases were increased BS diameter, increased BS-BSOB ratio and non-visualization of the CM. All the markers demonstrated high sensitivity and specificity but CM visibility reached the highest positive predictive value. Due to relatively high false positive rates, PCF measurements could not reach a satisfactory performance to validate their clinical use as a single marker. CM visibility has the advantage of being a qualitative marker and reduces the need for sophisticated and time-consuming measurements. Intracranial translucency and BS-BSOB ratio measurements should be used when the CM visibility is absent or in doubt.

Pendrin Expression in Preeclampsia: A Prospective Immunohistochemical Staining Study on Placental Bed Biopsies.

INTRODUCTION: To assess the pendrin expression density in placental bed biopsies from preeclampsia cases in comparison with healthy term controls. MATERIAL AND METHODS: A prospective case-control study with 106 placental bed biopsies obtained during cesarean deliveries. Pendrin expression was evaluated by immunohistochemical staining in different hypertensive disorders of pregnancy. RESULTS: Pendrin immunostaining frequency was higher in the hypertensive disorders group (p: 0.024), which was a result of the high frequency in the early-onset preeclampsia group. Uterine artery pulsatility indices were higher in pendrin positive patients than in the negatives in the case group. Gravidity was not found to affect the pendrin expression frequency in the placental bed. CONCLUSION: Placental ischemia seems to be an important determinant of pendrin expression in pregnant decidua. Increased pendrin density in early-onset preeclampsia could be a pathogenetic mechanism in or a part of the adaptational response to the development of the hypertension.

A prospective cohort study on the prediction of fetal distress and neonatal status with arterial and venous Doppler measurements in appropriately grown term fetuses.

PURPOSE: To assess the predictive power of the cerebro-placental ratio (CPR) and the venous-arterial index (VAI) for the development of intrapartum fetal distress (FD) and neonatal intensive care unit (NICU) admission. METHODS: Fetal umbilical artery, middle cerebral artery and umbilical vein Doppler measurements were obtained before the active phase of labor in 311 singleton pregnancies at ≥37 weeks. A continuous electronic fetal monitorization was applied, and an umbilical cord blood sample was obtained for each participant. FD and NICU admission were the primary outcomes. RESULTS: Labor was concluded as uncomplicated spontaneous vaginal delivery (SVD) in 261 (83.9%) cases. The 22 (7.1%) FD cases were subdivided into FD with NICU admission (n: 7; 2.3%) and without NICU admission (n: 15; 4.8%). Six out of 7 (85.8%) FD with NICU admission cases were from nulliparous pregnancies. The combinatory indices (VAI and CPR) reached the highest sensitivity (31.8%) and negative predictive value (94.7%). None of the fetuses, distressed or non-distressed, with CPR ≤ 10th percentile was born with a cord pH < 7.20. CONCLUSION: FD frequency was increased in fetuses with a low CPR or low VAI. However, the Doppler patterns were heterogeneous in both subgroups: FD with and without NICU admission. FD seems to be a common endpoint of different circulatory-metabolic disturbances. Parity affects the FD frequency in a manner related but not limited to fetal arterial and venous circulation. Low CPR could be a part of the adaptive mechanisms providing metabolic preparedness for hypoxic episodes.

A prospective study on first trimester prediction of ischemic placental diseases.

OBJECTIVE: The objective of the study is to assess the predictive power of mean uterine artery pulsatility index (UtA PI), maternal serum placental growth factor (PlGF) and placenta associated plasma protein A levels for the development of ischemic placental diseases (IPD) in a cohort of unselected singleton pregnancies during the first trimester combined test period. MATERIALS AND METHODS: A sample of 880 pregnancies was registered between September 2014 and January 2016. After routine examination for first trimester combined test, UtA PI was measured, and maternal serum was obtained and stored at -80 °C for PlGF assessment. RESULTS: Early-onset preeclampsia, late-onset preeclampsia and placental dysfunction-related fetal growth restriction were observed in 6 (0.7%), 17 (2.0%) and 27 (3.2%) cases, respectively. IPD requiring delivery before 34 weeks of gestation could be predicted with a sensitivity, specificity, positive predictive value and negative predictive value of 76.2%, 90.2%, 20.2% and 99.1%, respectively. CONCLUSION: A combination of UtA PI, placenta associated plasma protein A and PlGF was proven to be successful in the first trimester prediction of IPD, with the highest sensitivity in the subgroup who required delivery before 34 weeks of gestation. In reducing the number of pregnancies that should be followed-up, further studies for new biomarkers are needed. © 2017 John Wiley & Sons, Ltd.

Analysis of first-trimester combined test results in preparation for a cell-free fetal DNA era.

OBJECTIVE: To survey experience with the first-trimester combined test (FCT) for trisomy 21 (T21) in different risk score groups to determine the most useful clinical application of cell-free fetal DNA (cffDNA) screening. METHODS: In a retrospective study, the records of FCT results obtained at a center in Turkey between January 2009 and January 2014 were reviewed. The FCT results and rates of uptake of invasive diagnostic testing were compared among different risk score groups. RESULTS: FCT results were available for 4804 pregnancies; 276 (5.7%) had IDT results. Ten (72.7%) of 11 cases of T21 had a risk score of 1:300 or more. The IDT uptake rates were 54.5%, 51.9%, and 47.4% at risk scores of 1:100 or more, 1:200 or more, and 1:300 or more, respectively. In the group at intermediate risk (1:1001-1:3000), no pregnancy had an FCT result of both low pregnancy-associated plasma protein A and high free ß-human chorionic gonadotropin, but 30 (3.9%) of 766 pregnancies had both advanced maternal age and high ß-human chorionic gonadotropin. CONCLUSION: cffDNA screening should be used to optimize IDT uptake in pregnancies with a risk score of 1:101-1:1000. The selective power of the FCT diminishes beyond the 1:1001 score and cffDNA screening cannot yet be recommended routinely.

Do preeclampsia symptoms resolve after intrauterine death of a fetus?

We present two cases of twin pregnancies without resolution of preeclamptic symptoms after intrauterine death of one twin. CASE 1: A nulliparous woman aged 37 years was referred at 26 weeks of gestation because of arterial hypertension, edema, and growth restriction in one twin. Three weeks later the restricted twin died. During the following three weeks, ultrasound examinations showed a reduced growth velocity of the surviving fetus and reversed umbilical flow. At the end of the 34th week of gestation, cesarean section was performed and a healthy female infant was delivered. CASE 2: A nulliparous woman aged 33 years with a 27-week twin pregnancy was referred because of arterial hypertension and discordant growth. The restricted twin died at 31 weeks of gestation. Following the death, within two weeks the growth of the co-twin started to slow down and reversed end diastolic flow presented. At the end of the 33rd week of gestation, cesarean section was performed and a healthy female infant was delivered.The interesting point of these cases was the secondary effects on the co-twins. During the time after intrauterine deaths of one twin, the surviving fetuses started to show a reduced growth velocity and reversed umbilical flow and mothers had increased blood pressure and proteinuria again. We think that both cases are evidence of late on-set systemic maternal effects (such as systemic maternal endothelial activation and/or systemic maternal inflammatory response) depends on preeclampsia.

Termination of pregnancy for fetal abnormalities: main arguments and a decision-tree model.

INTRODUCTION: By looking through our ethical committee cases, we demonstrate the main arguments we use for making a judgment in face of fetal abnormalities. Our decision making model is a simplified algorithm of the arguments and concepts we use in scientific-ethic discussion. MATERIALS AND METHODS: A retrospective analysis was conducted from single, tertiary referral center of patients evaluated for fetal abnormalities from 2004 to 2014. We hypothesized that all our judgments would fit into a decision-tree model. RESULTS: 553 fetal abnormality cases were discussed, 348 (63%) were given termination of pregnancy (TOP) proposal. When detected <24 weeks, fetuses with chromosomal abnormality/genetic disorders (n:100) and with mental retardation risk (n:93) ended up with TOP proposal. For incompatibility with life cases (n:111) and the multimorbidity cases (n:44) the committee suggest TOP, regardless of gestational age. The highest family approval ratios were in chromosomal abnormalities/genetic disorders group (93%), and the lowest figures were in mental retardation risk group (80%). DISCUSSION: Continuously changing literature on prenatal and postnatal therapy options and the long term outcome of various fetal abnormalities influence committee decisions. Theoretical high success rates and inconsistent data on long term prognosis of some anomaly groups resulted in heterogenous decisions and various approval ratios.

A comparative study of obstetric outcomes in electively or spontaneously reduced triplet pregnancies.

PURPOSE: This study aimed at evaluating the pregnancy outcomes of IVF triplets which are spontaneously or electively reduced to twins and to compare them with non-reduced triplets and twins. METHODS: Retrospective analysis of trichorionic triplets and dichorionic twins of IVF pregnancies. RESULTS: Preeclampsia rate was significantly higher in triplet group (p = 0.014). Premature contractions requiring tocolysis were seen more often in spontaneous reduction and triplet groups compared to elective reduction and twin groups (p < 0.001). Elective reduction and twin groups had significantly lower rate of infants weighing less than 1,500 g than those of triplets (p < 0.001). Highest rate for infants weighing over 2,500 g was found in primary twin group. Preterm delivery rates were significantly lower in both twin and elective reduction groups compared to triplet and spontaneous reduction groups (p < 0.001). Proportion of women giving birth at term was not different in elective reduction and twin groups, and they were significantly higher compared to spontaneous reduction group (p = 0.024). Perinatal mortality rates of both elective reduction and twin groups were significantly less than those in the triplet group (p = 0.045 and p < 0.001, respectively). CONCLUSIONS: Obstetric outcomes of triplets from IVF or ovulation induction cycles undergoing elective reduction are better than ongoing triplet and spontaneous reduction groups and are similar to that of dichorionic twins.

Value of maternal procalcitonin levels for predicting subclinical intra-amniotic infection in preterm premature rupture of membranes.

AIM: To determine whether procalcitonin (ProCT) levels can be used to predict subclinical intra-amniotic infection by comparing maternal plasma levels in preterm premature rupture of membranes (PPROM) and premature rupture of membranes (PROM) at term with the levels in healthy pregnant women. METHODS: The mean plasma ProCT levels of 32 patients with PPROM, 35 patients with PROM at term, 24 healthy women at preterm gestation and 30 healthy women at term were compared. In the PPROM group, the presence or absence of histological chorioamnionitis and neonatal infection were used as a reference to analyze ProCT levels. RESULTS: The mean ProCT level of patients in the PPROM group was significantly higher than those in the PROM group and healthy controls. Patients in the PPROM group diagnosed with histological chorioamnionitis had significantly higher ProCT levels than those of the remaining patients. At a cut-off of 0.054 ng/mL, the sensitivity and specificity of ProCT to predict histological chorioamnionitis were 92.3% and 68.4%, respectively. CONCLUSION: ProCT levels were significantly higher in patients with PPROM, and facilitate identification of those who require expectant management.

Fetal circulatory variation in an acute incident causing bradycardia.

Umbilical artery\vein, middle cerebral artery, and ductus venosus Doppler velocimetry were performed at 33 weeks of gestation in the settings of an intrauterine growth restricted fetus during a heart rate deceleration. Interestingly, we recorded a sudden onset redistribution of fetal blood flow with fetal bradycardia. Spontaneous normalization of waveforms was observed once fetal heart rate returned to normal. Our case provides evidence to circulatory variation of a human fetus resulting from an acute incident causing bradycardia.

Early versus delayed oral feeding after cesarean delivery under different anesthetic methods--a randomized controlled trial anesthesia, feeding in cesarean delivery.

OBJECTIVE: The aim of the study was to evaluate the safety and efficacy of early feeding after cesarean delivery under different anesthetic methods. STUDY DESIGN: Two hundred women with elective cesarean delivery were randomly assigned to early oral feeding (EOF) or routine oral feeding (ROF) groups. EOF patients were informed that they could begin taking fluids orally (regime I) as soon as 2 hours after the delivery and then gradually progress to solid foods (regime III), if tolerated. ROF patients were informed that they could start regime I right after bowel sounds were heard on examination and then gradually move on to regime III. Hospitalization time and total time to ambulation (primary outcomes), gasstool discharge time and onset of bowel sounds (secondary outcomes) were compared in groups A [EOF patients after regional anesthesia (n=49)}, B [EOF patients after general anesthesia (n=48)}, C [ROF patients after regional anesthesia (n=47)} and 0 [ROF patients after general anesthesia (n=48)]. RESULTS: There were significant differences in primary and secondary outcomes between group A and the remaining groups, especially group D. The status of patients from group B was not better than group C. In fact, the latter were discharged home sooner and passage of gas, as well as initiation of regime I occurred earlier as compared to the former CONCLUSIONS: Cesarean section under regional anesthesia and encouragement of oral feeding 2 hours after the operation should be recommended in order to acnieve postoperative recovery and early hospital discharge. Routine oral feeding (right after bowel sounds are heard on examination) after cesarean section under general anesthesia should be the last choice.
