Crash sign: new first-trimester sonographic marker of spina bifida.

OBJECTIVES: To describe a new first-trimester sonographic sign, the 'crash sign', associated with fetal open spina bifida, and to evaluate its clinical usefulness in the first-trimester diagnosis of spina bifida. METHODS: This was a retrospective review of patients referred to three fetal medicine centers in the first trimester (11 + 0 to 13 + 6 weeks) with suspected spina bifida. Spina bifida was confirmed by direct visualization of the spinal defect on ultrasound by two experts and, when possible, by fetal postmortem examination. Ultrasound images were reviewed for the presence of the crash sign, which is the posterior displacement of the mesencephalon and deformation against the occipital bone in the axial view. The first-trimester ultrasound images of a mixed group of 10 cases and 40 control fetuses without spina bifida were assessed for the presence of the crash sign by two assessors blinded to the diagnosis. RESULTS: The crash sign was present in 48 out of 53 confirmed cases of spina bifida. Of these, 27 had isolated spina bifida and 21 had an associated anomaly. Of the five cases without the crash sign, one had isolated spina bifida and four had an associated anomaly. The crash sign was not reported in any of the control fetuses. CONCLUSIONS: We have described a new first-trimester sonographic marker for the diagnosis of spina bifida. Our results suggest that the crash sign may be a useful tool in the first-trimester detection of spina bifida. Prospective evaluation of the crash sign would be beneficial, ideally in a routine clinical screening ultrasound setting. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.

First Trimester Ultrasound Diagnosis of Right Aortic Arch (RAA).

OBJECTIVES: In the present research we proposed to evaluate the cases diagnosed in the first trimester of pregnancy by ultrasound with RAA, knowing the fact that although, in most cases the disease is isolated and asymptomatic, in some cases the presence of RAA can be associated with other fetal structural abnormalities that must be detected and monitored during pregnancy. We established correlations between the postnatal or anatomopathological examination (in cases ended by therapeutic abortion) and the presence of RAA detected in the first trimester. MATERIAL AND METHOD: We conducted a retrospective analytical study that investigated the role of the RAA early detection (isolated or associated with other cardiac abnormalities) for a correct pregnancy monitoring and postpartum management. Between 2012 and 2018, patients admitted in the first Obstetrics and Gynecology Clinic-the Prenatal Diagnostic Unit-of the Emergency County Hospital from Craiova, were evaluated in the first trimester of pregnancy for genetic abnormalities and early morphology. The study material was represented by the patient's medical records (observation sheets, surgical protocol records, anatomopathological diagnostic records). The obtained information was stored in Microsoft Excel files and statistically processed. RESULTS: During the study period, 14 cases with right aortic arch were diagnosed in the first and second trimester of pregnancy. 4 cases were detected in the first trimester: 2 cases (50%) presented left ductus arteriosus (DA)-RAA type 2 ("U" sign) and 2 cases (50%) presented right DA-RAA type 1 (mirror image-"V" sign). RAA type 1 associated Tetralogy of Fallot in one case (25%) and in another one case (25%) the anomaly was isolated. RAA type 2 associated atrio-ventricular septal defect (AVSD) in one case (25%) and in another one case (25%) the anomaly was isolated. There were no fetal extracardiac structural abnormalities associated with the RAA diagnosis in the first trimester. CONCLUSIONS: Over a seven years study period (2012-2018), 14 cases with RAA in the first and second trimester of pregnancy were detected. In the low-risk pregnancies group, the first trimester incidence of the RAA was 0.11% and the association of congenital heart abnormalities was 50%.

Implications of the First Trimester 2d and 3d Ultrasound in Pregnancy Outcome.

BACKGROUND: In this study we researched for the first trimester pregnancy measurements by transabdominal and transvaginal ultrasound: gestational sac volume (GSV), embryo volume (EV), placenta volume (PV), yolk sac volume (YSV) and crown rump lengh (CRL) in predicting pregnancy outcome. Our goals was to demonstrate the ability of the first trimester ultrasound in identifying patients at high risk for abortion, intrauterine growth restriction (IUGR) and low birth weight. METHODS: Prospective observational clinical study that investigated the role of the first trimester 2D and volumetric (3D) measurements in predicting pregnancy outcome. The study was carried out in the Obstetrics and Gynecology Department of the Emergency County Hospital in Craiova during a study period of 3 years (between 2016 and 2018). The study included a number of 87 pregnancies. Patients included in the study were offered an early 2D and 3D transabdominal and transvaginal ultrasound and afterwards they were followed up until delivery. The statistical analyses (standard deviation, coefficient of variety, Cohen K correlation coefficient) determined a correlation between the two ultrasound methods, between the values of these parameters and pregnancy prognosis, the correlation being more relevant for the 3D ultrasound. The GSV, EV, YSV, PV, CRL and pregnancy outcome was established. RESULTS: Our study showed that the concordance degree between the two methods was 89.7%. 3D ultrasound had a diagnostic impact in 96.6% of the cases, while 2D ultrasound had a diagnostic impact in 89.6% of the cases. The incidence of the patients at high risk for complications was recorded in pregnancies with abnormal early ultrasound markers. CONCLUSIONS: First trimester ultrasound is a capable method for identifying a higher percentage of patients at risk of pregnancy complications, counseling and monitoring compared to 2D ultrasound. Also, because there is no radiation exposure, the risks are non-existent.

Ultrasound Evaluation of Fetal Biometry and Doppler Parameters in the Third Trimester of Pregnancy Suspected of Intrauterine Growth Restriction.

PURPOSE: The purpose of this study was to investigate fetal biometry and Doppler parameters in the third trimester of pregnancy with suspected restriction of fetal growth as potential predictors of unfavorable neonatal status. MATERIAL/METHODS: The uterine artery, umbilical and middle cerebral artery, cerebroplacental ratio (CPR), and estimated fetal weight (EFW) were evaluated in a cohort of 126 pregnancies that resulted in the birth of a fetus <10 percentiles (SGA). RESULTS: The demographic data of the studied cases did not show a significant difference between the parameters studied in the two study groups: Late SGA fetuses and Early SGA fetuses. Analyzing fetal biometry we found a significant difference for some parameters in relation to the two study groups. Our study showed that the Early SGA fetuses group had a lower birth weight, a lower gestational age at birth, an increase in the incidence of premature birth with an increase in Doppler abnormal incidence. CONCLUSIONS: Ultrasound examination and Doppler monitoring provide a non-invasive repetitive method for supervising fetuses with growth restriction in order to apply an adequate management.

Postpartum Spontaneous Subcapsular Hepatic Hematoma (SSHH)- Conservative Management. Case Report and Review of Literature.

Spontaneous subcapsular hematoma of the liver, with no history of preeclampsia and HELLP syndrome (Hemolysis, Elevated Liver enzymes, and Low Platelet count.), represents an exceptionally rare clinical condition in pregnancy and postpartum. The complications can be devastating in terms of fetal and maternal mortality. We hereby present a case of a 33-year-old female that underwent an emergency Cesarean section (C-section) at term with the extraction of a live foetus. Few hours after delivery, she complained of intense epigastric and abdominal pain. The diagnostic work-up suggested a SSHH. The condition was managed conservatively in a multidisciplinary team.

A rare occurrence of three consecutive autosomal trisomic pregnancies in a couple without offspring.

BACKGROUND: Trisomies are the most common chromosomal abnormalities, being a major cause of pregnancy loss in the first trimester. Data from preimplantation embryos support the concept of recurrent aneuploidy in women with recurrent abortion. CASE: The authors report a rare case with three different consecutive trisomic pregnancies: 47,XY,+21, 47,XX,+9, and 47,XX,+18. All pregnancies resulted from the same relationship and no consanguinity was present. Standard clinical cytogenetic analysis indicated that both members had normal peripheral blood karyotype, with no evidence of mosaicism in either patient or her partner. CONCLUSION: The present report sup- ports the hypothesis that some women have a higher risk for nondisjunction than others of the same age. Counseling a couple with re- current trisomies is difficult and future research on genetics of cell division are required to assist them.

Prematurity and Sepsis - Features and Approach Difficulties During Neonatal Emergency Transfer.

Purpose - We aimed to identify conditions, means and methods of suspecting, certification and stratification of neonatal sepsis, to prioritize and define levels of management during evacuation, and to follow the neonatal sepsis succeeding the transfer. Material and method - An observational study was conducted between 1January 2011 - the 1 January 2015, that included 610 preterm newborns with suspected sepsis transferred by UTIM NN or HEMS Craiova. We statistically studied confirmation rate of suspected sepsis, the sepsis onset condition, severity stratification, and correlate with medical centers performance assisting newborns and planning transfers. A follow up performed two weeks after evacuation. Results - We detected low rate of detection and affirmed sepsis: n=38 (6.25%) - C.I. (95%): 4.454309335 and very high level of founded unsuspected sepsis: n=85 (13.98026316%) C.I. (95%): 4.982552268, 9of them being very low body weight newborns (1.480263158%). High rate of founded, unaffirmed respiratory distress 23.35526316% (n=142), C.I. (95%): 5.383960957, as sign of sepsis. High rate of accidental hypoglycemia/hypothermia founded by emergency evacuation team: n=131 (21.54605263%), especially to VLBW newborns, associate with sepsis, respiratory failure or confounding with. Conclusions - Newborns transfer its self generates multiple additional risks, including sepsis, but not neglected any stress generated by transport conditions, so that ,,in utero'' transfer has to be extended in current practice for high risk fetus, mother or special medical conditions to limit newborns transfers. Wider use of telemedicine would facilitate refining the transfer criteria.

Assessment of Oxidative Stress Genes SOD2 and SOD3 Polymorphisms Role in Human Colorectal Cancer.

PURPOSE: The aim of this study was to ascertain the oxidative stress genes SOD2 and SOD3 polymorphisms in patients with colorectal cancer and to assess the possible involvement of these polymorphisms that might increase the risk for patients to develop malignant intestinal tumors. MATERIAL AND METHODS: A total number of 306 subjects were divided into two groups (109 colorectal cancer patients as the study group and 197 normal healthy individuals as the control group).We genotyped two polymorphisms, SOD2 - 201A>G (rs4880) and SOD3 - 896C>G (rs1799895), by allelic discrimination, with TaqMan RT-PCR specific probes. RESULTS: No significant differences were found with either of the polymorphisms when comparing the association between them and an increased risk of developing colorectal tumors. CONCLUSION: In Romanian population, the risk of developing colorectal cancer is not increased by SOD2 and SOD3 polymorphisms.

In Vivo Experimental Study of an Endoscopic Ultrasound Multifunctional Radiofrequency Ablation Probe.

The aim of our study was to test the feasibility of a new developed RFA probe made especially for EUS use and also capable of injecting iron oxide nanoparticles within the targeted liver area. The procedures were performed on domestic pigs, divided in groups: A.liver RFA was performed; B -IONs were injected in the liver followed by EUS-RFA in the same area; C.local EUS-guided liver IONs injection were performed. After EUS measurements for the ablation areas, group A had a mean of 4.9 cm, while group B had a mean of 5.2 cm (Fig.3, 4). IONs exposure was on a median area of 3.1 cm. EUS imaging pointed out a regular oval shape in group A, and a slightly irregular outline on group B, with more echo bubbles around. MRI sections revealed different patterns for each group separately. In group A and B, RFA lesions were easily identified with specific liver parenchyma changes. Group B revealed few deposits of nanoparticles further away from the targeted point. The last group pointed out a large amount of IONs within the injection region and a larger amount of dispersed IONs within the liver than group B.

Study of the Etiological Spectrum of Spontaneous Bacterial Peritonitis in a Group of Patients Suffering from Liver Cirrhosis.

INTRODUCTION: Spontaneous bacterial peritonitis (SBP) represents the most severe and common infectious complication in patients suffering from liver cirrhosis. The objectives of the study were the evaluation of the risk factors responsible for the occurrence of the spontaneous bacterial peritonitis in a group of patients suffering from liver cirrhosis, the identification of the bacterial spectrum and assessing the response to antibiotic therapy. Material and method - The studied group included 64 patients suffering from liver cirrhosis, with an episode of SBP, who were admitted to the IInd Medical Clinic of the County Hospital of Craiova, within a period of 24 months. The control group included 61 patients with liver cirrhosis with an episode of decompensation of liver disease. The diagnosis of liver cirrhosis was established by using clinical, biological and imagistic criteria, and the SBP's diagnosis was based on cytological and bacteriological analysis of the ascites fluid. Patients suffering from hepatocellular carcinoma, portal vein thrombosis and other infectious conditions were excluded. The anamnesis, the duration of the disease, the alcohol intake, the complete clinical examination, the clinical, biological and imagistic evaluation were monitored. Results and conclusions - The most frequent etiology of SBP is represented in 67% of the cases by Gram negative germs, and thus, the antibiotic therapy will be orientated against this etiological segment. In what antibiotic sensitivity is concerned, most of the germs were sensitive to third generation cephalosporins, quinolones, carbapenems and vancomycin.

The Angle of Progression at Station 0 and in Magnetic Resonance and Transperineal Ultrasound Assessment.

The transperineal ultrasound (TPU) value of the angle of progression (AOP) during fetal head engagement, at station 0, is a critical cut-off for current obstetrical practice, especially when intrapartum instrumental interventions are required. Still, controversial measurements were reported in previous high resolution imagistic studies. Our TPU and direct "gold-standard" magnetic resonance (MRI) measurements confirm that station 0 corresponds to a 120° AOP, concordantly. Based on these findings, the fact that an AOP of 120° or greater was previously strongly associated with vaginal delivery may be due to the achievement of head engagement in labor.

Acceptability of Intrapartum Ultrasound Monitoring - Experience from a Romanian Longitudinal Study.

OBJECTIVES: To assess the acceptability of intrapartum ultrasound (IPUS) labor monitoring in unselected Romanian women attending a tertiary maternity unit and the patients' experience of the examination (i.e. the perceived difficulty regarding the evaluation protocol). METHODS: The research was a prospective longitudinal observational study on unselected low-risk women that delivered in our unit. IPUS monitoring of active labor was proposed for observational purposes in low-risk population. Transabdominal and transperineal scans were performed hourly in the first stage of labor and at every 15 minutes in the second stage. The second day after birth, consenting women were invited to take part in a questionnaire survey with features regarding the patient's impression about the ultrasound monitoring scans during labor, and the acceptability of having an IPUS protocol for labor monitoring in the future. RESULTS: From 200 parturient women questioned, 98% of them agreed to IPUS investigation protocol. The demographic characteristics did not influence the acceptance. However, due to the small number of women declining IPUS we were not able to compare the characteristics and perceptions of women who declined the scan with those who accepted it. Most of the women (93% of accepters and 75% of decliners) had little difficulty deciding whether or not to have the scan protocol. All laboring women who had the IPUS scan found it an acceptable experience; 21% of women without epidural anesthesia rated the perceived difficulty as "mild" or "discomforting". Women rated having the IPUS scan as being significantly less difficult than having a cervical smear, transvaginal scan or having a digital clinical evaluation. 67% of the studied patients expressed increased confidence while being able to follow along the medical personnel the progression of the labor on the ultrasound screen. 97% of the consenting women who had the IPUS scans and all the 4 decliners said they would definitely or probably agree such ultrasound monitoring in a future labor, if this technique is proven useful for the labor outcome. CONCLUSIONS: IPUS protocol for labor monitoring was overwhelmingly acceptable in our population of women, despite the fact that they were learning about the procedure for the first time. The demographic characteristics did not influence acceptance, but due to the high rate of acceptance, predictors of acceptance could not be analyzed. More than two thirds of the patients expressed increased confidence while being able to follow along the medical personnel the progression of the labor on the ultrasound screen and almost all the participants were willing to have the procedure again in future, further reinforcing their favorable attitude to the procedure.

Agenesis of ductus venosus in sequential first and second trimester screening.

OBJECTIVE: The goal of this study is to evaluate the potential of first trimester (FT) screening in the diagnosis of agenesis of the ductus venosus (ADV) and to study its prevalence in a low-risk population, the associated conditions, and pregnancy outcome. METHOD: Prospective, sequential screening study at two tertiary units with morpho-functional evaluation of the ductus venosus during the first and second trimester screening. We quantified the FT detection rate, prevalence, and associated conditions: umbilical shunting type, concomitant anomalies, and outcome. RESULTS: In 6114 consecutive pregnancies, we identified 11 cases of ADV. Ten (91%) were identified during the FT examination. The prevalence was 1 in 556, similar for both centers (1/478 vs. 1/691). Major structural defects and fetal effusions were detected in 8 (73%). twenty two percent had a major chromosomal abnormality. In 3 cases, the anomaly was isolated and had normal outcome, independent of liver by-pass, caliber of the shunt, and NT thickness. CONCLUSIONS: Agenesis of the ductus venosus can be detected during FT. The early detection of ADV is important given its high association with major abnormalities.

Improved detection rate of structural abnormalities in the first trimester using an extended examination protocol.

OBJECTIVE: To assess the potential of first-trimester sonography in the detection of fetal abnormalities using an extended protocol that is achievable with reasonable resources of time, personnel and ultrasound equipment. METHODS: This was a prospective two-center 2-year study of 5472 consecutive unselected pregnant women examined at 12 to 13 + 6 gestational weeks. Women were examined using an extended morphogenetic ultrasound protocol that, in addition to the basic evaluation, involved a color Doppler cardiac sweep and identification of early contingent markers for major abnormalities. RESULTS: The prevalence of lethal and severe malformations was 1.39%. The first-trimester scan identified 40.6% of the cases detected overall and 76.3% of major structural defects. The first-trimester detection rate (DR) for major congenital heart disease (either isolated or associated with extracardiac abnormalities) was 90% and that for major central nervous system anomalies was 69.5%. In fetuses with increased nuchal translucency (NT), the first-trimester DR for major anomalies was 96%, and in fetuses with normal NT it was 66.7%. Most (67.1%) cases with major abnormalities presented with normal NT. CONCLUSIONS: A detailed first-trimester anomaly scan using an extended protocol is an efficient screening method to detect major fetal structural abnormalities in low-risk pregnancies. It is feasible at 12 to 13 + 6 weeks with ultrasound equipment and personnel already used for routine first-trimester screening. Rate of detection of severe malformations is greater in early- than in mid-pregnancy and on postnatal evaluation. Early heart investigation could be improved by an extended protocol involving use of color Doppler.

First trimester two- and four-dimensional cardiac scan: intra- and interobserver agreement, comparison between methods and benefits of color Doppler technique.

OBJECTIVE: To evaluate intra- and interobserver agreement for first-trimester fetal cardiac structural assessment, using two-dimensional (2D) ultrasound (2D-US) and 4D-US (4D spatiotemporal image correlation (STIC) technology), to compare the methods and to assess the advantages of adding color Doppler to each technique. METHODS: Digital videoclips (B-mode and color Doppler) and 4D-STIC volumes (gray-scale and color Doppler) from 632 pregnancies with normal fetal hearts were acquired and stored at the time of detailed first-trimester ultrasound examination. Later analysis on a randomized sample of 100 cases was performed, targeting 11 cardiac structures and features. We compared visualization of fetal heart parameters using 2D-US vs 4D-US and gray-scale vs color Doppler imaging. RESULTS: STIC volumes were considered satisfactory (adequate visualization of at least 8/11 parameters) in 78% of cases and 2D-US acquisitions in 89% of cases. The intra- and interobserver agreement was good for both 2D and 4D methods (kappa > 0.6), and the percentage overall agreement was very high using both methods (95%). 2D- and 4D-US identification of the fetal cardiac parameters did not differ significantly. The differences between gray-scale and color Doppler imaging were statistically significant in identifying similar key cardiac parameters, for both 2D- and 4D-US (P < 0.05). CONCLUSION: Both 2D and 4D methods for assessing first-trimester heart parameters are feasible and repeatable within and between observers. Color Doppler adds valuable information to both methods.
