Analyzing the factors that contribute to the development of embryological classical type of bladder exstrophy

Bladder exstrophy is a rare congenital condition of the pelvis, bladder, and lower abdomen that opens the bladder against the abdominal wall, produces aberrant growth, short penis, upward curvature during erection, wide penis, and undescended testes. Exstrophy affects 1/30,000 newborns. The bladder opens against the abdominal wall in bladder exstrophy, a rare genitourinary condition. This study is vital to provide appropriate therapy choices as a basis to improve patient outcomes. This study may explain bladder exstrophy and provide treatment. Epispadias, secretory placenta, cloacal exstrophy, and other embryonic abnormalities comprise the exstrophy-spades complex. The mesenchymal layer does not migrate from the ectoderm and endoderm layers in the first trimester, affecting the cloacal membrane. Embryological problems define the exstrophy-aspidistra complex, which resembles epimedium, classic bladder, cloacal exstrophy, and other diseases. Urogenital ventral body wall anomalies expose the bladder mucosa, causing bladder exstrophy. Genetic mutations in the Hedgehog cascade pathway, Wnt signal, FGF, BMP4, Alx4, Gli3, and ISL1 cause ventral body wall closure and urinary bladder failure. External factors such as high maternal age, smoking moms, and high maternal body mass index have also been associated to bladder exstrophy. Valproic acid increases bladder exstrophy risk; chemicals and pollutants during pregnancy may increase bladder exstrophy risk. Bladder exstrophy has no identified cause despite these risk factors. Exstrophy reconstruction seals the bladder, improves bowel function, reconstructs the vaginal region, and restores urination.

"We All Want to Be Able to Tell You Something Hopeful": Clinicians' Experiences Providing Maternal-Fetal Surgery Counseling

INTRODUCTION

Prenatal counseling about maternal-fetal surgery can be traumatic and confusing for pregnant people. It can also be technically and emotionally complex for clinicians. As maternal-fetal surgery rapidly advances and becomes more common, more evidence is needed to inform counseling practices. The objective of this study was to develop a deeper understanding of the methods clinicians currently use to train for and provide counseling, as well as their needs and recommendations for future education and training.

METHODS

We used interpretive description methods and interviewed interprofessional clinicians who regularly counsel pregnant people about maternal-fetal surgery.

RESULTS

We conducted 20 interviews with participants from 17 different sites who were maternal-fetal medicine specialists (30%), pediatric surgeons (30%), nurses (15%), social workers (10%), a genetic counselor (5%), a neonatologist (5%), and a pediatric subspecialist (5%). Most were female (70%), non-Hispanic white (90%), and practiced in the Midwest (50%). We identified four overarching themes: (1) contextualizing maternal-fetal surgery counseling; (2) establishing shared understanding; (3) supporting decision-making; and (4) training for maternal-fetal surgery counseling. Within these themes, we identified key practice differences among professions, specialties, institutions, and regions.

CONCLUSION

Participants are committed to practicing informative and supportive counseling to empower pregnant people to make autonomous decisions about maternal-fetal surgery. Nevertheless, our findings indicate a dearth of evidence-based communication practices and guidance. Participants identified significant systemic limitations affecting pregnant people's decision-making options related to maternal-fetal surgery.

Counseling for the option of termination of pregnancy for severe fetal anomalies in light of the recent Supreme Court ruling to remove the constitutional right to an abortion

A birth defect is a structural or chromosomal change present at birth that can affect almost any part or parts of the body. Birth defects can vary from mild to severe. On June 24, 2022, with its Dobbs v Jackson Women's Health Organization decision the Supreme Court of the United States overturned Roe v. Wade, removing the longstanding landmark 1973 ruling that secured a person's constitutional right to an abortion. With this decision individual states can now decide their own abortion laws. In about one-half of the states that continue the legality of pregnancy termination, the process of offering, discussing, and performing terminations of pregnancy remain the same as previously. In states where abortions are not legal, there will be conflicts between the law and the ethical responsibility of physicians to offer and discuss termination of pregnancy for severe anomalies.

Women's worries about prenatal screening tests suspected of fetal anomalies: a qualitative study

BACKGROUND

Pregnant women with suspected fetal anomalies experience a great deal of stress following prenatal screening tests. The present study aimed to investigate women's worries about prenatal screening tests suspected of fetal anomalies.

METHODS

Through the use of qualitative content analysis, the reports of women whose prenatal screening tests were suspected of fetal anomalies were analyzed and the results were interpreted. The participants were selected from four public and private maternity care clinics of Babol, Iran, from December 2021 to January 2022, using targeted convenience sampling. Data were collected from 20 women aged 24 to 41 years old, who underwent prenatal screening tests and were suspected of fetal anomalies, using semi-structured face-to-face interviews.

RESULTS

The four main themes included the "causes of worries" (with sub-themes of challenge with spouse and relatives, medical diagnosis processes, previous unpleasant experiences, physical and mental problems, financial worries, and misinformation), "anxiety-coping styles" (with cognitive emotion-oriented, behavioral emotion-oriented, and problem-oriented sub-themes), "reactions to a possible diagnosis of anomaly" (with three sub-themes, namely concealment, extreme fear and worry, and denial), and "attribution of the cause of the anomaly" (with sub-themes of consanguine marriage, evil eyes, tendency to have a baby of a particular gender, a history of anomalies in the previous child, the spouse's medical illness, unplanned pregnancy, and high maternal anxiety).

CONCLUSION

Women with suspected fetal anomalies experience a great deal of stress, the most important reason for which is the "physician's uncertainty". "Sharing worries with relatives" was the most common style of coping with worries. Establishing emotional support and empathetic communication between midwives and physicians with pregnant women suspected of fetal anomalies were important ways to reduce their worries.

Investigating informed choice in screening programmes: a mixed methods analysis

BACKGROUND

Screening programmes aim to identify individuals at higher risk of developing a disease or condition. While globally, there is agreement that people who attend screening should be fully informed, there is no consensus about how this should be achieved. We conducted a mixed methods study across eight different countries to understand how countries address informed choice across two screening programmes: breast cancer and fetal trisomy anomaly screening.

METHODS

Fourteen senior level employees from organisations who produce and deliver decision aids to assist informed choice were interviewed, and their decision aids (n = 15) were evaluated using documentary analysis.

RESULTS

We discovered that attempts to achieve informed choice via decision aids generate two key tensions (i) between improving informed choice and increasing uptake and (ii) between improving informed choice and comprehensibility of the information presented. Comprehensibility is fundamentally at tension with an aim of being fully informed. These tensions emerged in both the interviews and documentary analysis.

CONCLUSION

We conclude that organisations need to decide whether their overarching aim is ensuring high levels of uptake or maximising informed choice to participate in screening programmes. Consideration must then be given to all levels of development and distribution of information produced to reflect each organisation's aim. The comprehensibility of the DA must also be considered, as this may be reduced when informed choice is prioritised.

Factors influencing parental decisions to terminate pregnancies following prenatal diagnoses of major fetal anomalies at Ramathibodi Hospital, Bangkok, Thailand

Background

The rate of termination of pregnancy (TOP) for fetal anomalies and the factors affecting TOP vary among different populations. Optimisation of prenatal care and counselling requires understanding the factors influencing parental decisions in the relevant population. This study aimed to evaluate the rate of TOP after diagnoses of major fetal anomalies and assess factors associated with TOP-related decisions at a university hospital in Thailand.

Methods

A retrospective chart review was conducted at the Fetal Anomaly Clinic of Ramathibodi Hospital, Bangkok, Thailand. Medical records of all women with singleton pregnancies prenatally diagnosed with major fetal anomalies before 24 gestational weeks between 2010 and 2020 were reviewed.

Results

During the study period, 461 cases of major fetal anomalies were diagnosed, and 264 (57.3%) of these pregnancies were terminated. Three factors influencing parental TOP decisions were lethal anomalies (odds ratio [OR], 197.39; 95% confidence interval [CI], 49.95–779.95; p < 0.001), presence of genetic abnormalities (OR, 10.19; 95% CI, 4.17–24.87; p < 0.001) and gestational age at diagnosis (OR, 0.74; 95% CI, 0.65–0.84; p < 0.001).

Conclusions

Over half of the pregnant women whose records were reviewed and who were prenatally diagnosed with major fetal anomalies terminated their pregnancies. Fetal factors, particularly lethality, genetic abnormalities and early gestational age at diagnosis, showed the most powerful associations with parental TOP decisions. Other maternal background factors were not key considerations.

Retrospective clinical evaluation of indications for termination of pregnancies due to fetal anomaly

Objective:

To assess the indications for termination of pregnancy (TOP) in pregnant patients who were followed up with suspicion of fetal anomaly in a Turkish tertiary referral center.

Material and Methods:

This retrospective study was carried out in patients who were followed up with suspicion of fetal anomaly between May 2016 and May 2019 at the Perinatology Clinic of Obstetrics and Gynecology Department in Pamukkale University Hospital, which is a tertiary hospital in Denizli province in Turkey. Women were divided into two depending on gestational period: group 1 ≤22 weeks; and group 2 (>23 weeks of gestation).

Results:

Four hundred and seventeen pregnant women were evaluated and TOP was performed at a mean gestational age of 27.7±6.3 weeks. There were 308 (73.8%) women in group 1 and 109 (26.2%) in group 2. The decision to terminate pregnancy was due to fetal anomaly in 117 (28.1%). The majority of termination pregnancies in group 2 were performed because of multiple malformations and/or central nervous system defects. All chromosomal diseases were detected in group 1.

Conclusion:

With a good perinatal screening program, fetal anomalies can be diagnosed early. Therefore, early TOP is possible. Thus, pregnancy termination can be made before reaching the life limit.

Fetal anomalies in gestational diabetes mellitus and risk of fetal anomalies in relation to pre-conceptional blood sugar and glycosylated hemoglobin

BACKGROUND

The risk of fetal anomalies (FAs) is increased in infants of diabetic mothers. FAs are closely related to the glycosylated hemoglobin (HbA1c) level in pregnancy.

OBJECTIVES

To detect the prevalence of FAs in women with gestational diabetes mellitus (GDM).

MATERIAL AND METHODS

157 pregnant women with GDM were included in this study, and data from 151 women were analyzed. Beyond the regular antenatal check-up, the HbA1c was checked monthly during the antenatal follow-up. Collected data after delivery were analyzed to detect the prevalence of FAs in women with GDM and the risk of FAs in relation to the pre-conceptional blood sugar and HbA1c.

RESULTS

The FAs were recorded in 8.6% (13) of the 151 women with GDM. The recorded FAs were cardiovascular [2.6% (4)], musculoskeletal [1.3% (2)], urogenital [1.3% (2)], gastrointestinal [1.3% (2)], facial [0.7% (1)], central nervous system [0.7% (1)], and multiple FAs [0.7% (1)]. The uncontrolled pre-conceptional blood sugar significantly increased RR [RR 2.2 (95%CI: 1.7-2.9); P < 0.001], and odds of FAs [OR 17.05 (95%CI: 2.2-134.9); P = 0.007] in women with GDM. In addition, the HbA1c ≥6.5 significantly increased RR [RR 2.8 (95% CI: 2.1-3.8); P < 0.001], and odds of FAs [OR 24.8 (95% CI: 3.1-196.7); P = 0.002] in women with GDM.

CONCLUSION

In this study, the prevalence of FAs in women with GDM was 8.6%. Uncontrolled pre-conceptional blood sugar and HbA1c ≥6.5 in the first trimester significantly increased the relative risk and the odds of FAs.

The Future of Fetal Surgery

The field of fetal medicine has evolved significantly over the past several decades. Our ability to identify and treat the unborn patient has been shaped by advancements in imaging technology, genetic diagnosis, an improved understanding of fetal physiology, and the development and optimization of in utero surgical techniques. The future of the field will be shaped by medical innovators pushing for the continued refinement of minimally invasive surgical technique, the application of pioneering technologies such as robotic surgery and in utero stem cell and gene therapies, and the development of innovative ex utero fetal support systems.

Sonographic abnormalities in pregnancies conceived following IVF with and without preimplantation genetic testing for aneuploidy (PGT-A)

Purpose

To report the rate of fetal anomalies detected on anatomy ultrasound in pregnant patients who underwent IVF with preimplantation genetic testing for aneuploidy (PGT-A) compared to patients who conceived following IVF with unscreened embryos and age-matched patients with natural conceptions.

Methods

Retrospective cohort study at a single maternal-fetal medicine practice. Patients with singleton pregnancies who had a mid-trimester anatomy ultrasound between January 2017 and December 2018 were screened for inclusion. A total of 712 patients who conceived after IVF with or without PGT-A were age-matched with natural conception controls. The primary outcome was the rate of fetal and placental anomalies detected on mid-trimester anatomical survey. Secondary outcomes included the rates of abnormal nuchal translucency (NT), second trimester serum analytes, non-invasive prenatal testing (NIPT), and invasive diagnostic testing.

Result(s)

There were no differences in the rate of fetal anomalies in patients who underwent IVF with PGT-A compared to patients who conceived following IVF with unscreened embryos and age-matched patients with natural conceptions. Rate of abnormal NT, high-risk NIPT, and abnormal invasive diagnostic testing were also similar. Patients who conceived after IVF with or without PGT-A had higher rates of abnormal placental ultrasound findings and abnormal second trimester serum analytes compared to natural conception controls.

Conclusion

The use of PGT-A was not associated with a difference in risk of fetal anomaly detection on a mid-trimester anatomical survey. The results of this study highlight the importance of improved patient counseling regarding the limitations of PGT-A, and of providing standard prenatal care for pregnancies conceived through ART, regardless of whether PGT-A was performed.

ACR Appropriateness Criteria® Nuchal Translucency Evaluation at 11 to 14 Weeks of Gestation

A fetus with an increased nuchal translucency at 11 to 14 weeks gestation is at risk for aneuploidy, genetic syndromes, structural anomalies, and intrauterine fetal demise in both single and twin gestations. In addition to referral to genetics for counseling and consideration of diagnostic genetic testing, a detailed anatomic survey and fetal echocardiogram are indicated in the second trimester to screen for congenital malformations and major heart defects. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Prognostic significance of prenatal ultrasound in fetal arthrogryposis multiplex congenita

Purpose

Fetal arthrogryposis multiplex congenita (AMC) describes a heterogeneous disease entity characterized by multiple contractures affecting at least two different body areas. The aim of our study was to identify additional sonographic abnormalities in fetuses with AMC Type I–III associated with an unfavorable prognosis and to describe when those signs were first detected.

Methods

This retrospective study included 41 pregnancies of suspected AMC diagnosed 1999–2017 at our tertiary referral center. The affected pregnancies were divided into the 3 AMC subgroups; the time of detection and outcome were analyzed. Prenatal sonograms, pediatric charts, genetic tests, and autopsy reports were studied.

Results

Pregnancy outcome data were verifiable in 34 out of 41 cases; in 27 cases, AMC was confirmed. Hydrops was present in 50% of postnatally deceased fetuses, 53% of cases resulting in termination of pregnancy vs. 0% of the surviving 8 children. Absent stomach filling was found in 67% of the children with neonatal death. After subcategorization, the limb-involvement-only-group, 8% showed hydrops vs. 100% in system anomaly group vs. 70% in neuromuscular dysfunction cohort (p = 0.001). Scoliosis, nuchal edema, and absent stomach filling were significantly indicating for a neurological etiology.

Conclusion

In addition to disease-defining sonographic findings, those with prognostic significance were identified. Hydrops, nuchal edema, scoliosis and absent stomach filling were associated with unfavorable outcomes implicating a neuromuscular etiology. This knowledge can help to predict the further course of the disease and support patient counseling.

First trimester anomaly scan using virtual reality (VR FETUS study): study protocol for a randomized clinical trial

Background

In recent years it has become clear that fetal anomalies can already be detected at the end of the first trimester of pregnancy by two-dimensional (2D) ultrasound. This is why increasingly in developed countries the first trimester anomaly scan is being offered as part of standard care. We have developed a Virtual Reality (VR) approach to improve the diagnostic abilities of 2D ultrasound. Three-dimensional (3D) ultrasound datasets are used in VR assessment, enabling real depth perception and unique interaction. The aim of this study is to investigate whether first trimester 3D VR ultrasound is of additional value in terms of diagnostic accuracy for the detection of fetal anomalies. Health-related quality of life, cost-effectiveness and also the perspective of both patient and ultrasonographer on the 3D VR modality will be studied.

Methods

Women in the first trimester of a high risk pregnancy for a fetus with a congenital anomaly are eligible for inclusion. This is a randomized controlled trial with two intervention arms. The control group receives ‘care as usual’: a second trimester 2D advanced ultrasound examination. The intervention group will undergo an additional first trimester 2D and 3D VR ultrasound examination. Following each examination participants will fill in validated questionnaires evaluating their quality of life and healthcare related expenses. Participants’ and ultrasonographers’ perspectives on the 3D VR ultrasound will be surveyed. The primary outcome will be the detection of fetal anomalies. The additional first trimester 3D VR ultrasound examination will be compared to ‘care as usual’. Neonatal or histopathological examinations are considered the gold standard for the detection of congenital anomalies. To reach statistical significance and 80% power with a detection rate of 65% for second trimester ultrasound examination and 70% for the combined detection of first trimester 3D VR and second trimester ultrasound examination, a sample size of 2800 participants is needed.

Discussion

First trimester 3D VR detection of fetal anomalies may improve patients’ quality of life through reassurance or earlier identification of malformations. Results of this study will provide policymakers and healthcare professionals with the highest level of evidence for cost-effectiveness of first trimester ultrasound using a 3D VR approach.

Antenatally detected abdominal cyst: Does cyst size and nature determine postnatal symptoms and outcome?

BACKGROUND

The outcome of antenatally detected fetal intra-abdominal cysts is highly variable and challenging to predict. Antenatal ultrasound scans may be of value in predicting postnatal outcome.

AIMS

To report antenatal and postnatal course of fetal intra-abdominal cysts identified on antenatal ultrasound and establish the value of cyst dimensions for predicting outcome.

STUDY DESIGN

Retrospective observational study.

SUBJECTS

All intra-abdominal cysts diagnosed in a single centre between 2013 and 2019.

OUTCOME MEASURES

Cyst characteristics were recorded from radiological reports and postnatal diagnosis and outcomes documented. Growth characteristics were identified to distinguish different diagnosis. The maximum antenatal diameter of all cysts was identified and the best cut-off diameter to predict whether a cyst would persist postnatally or require surgery was identified. Best cut-off values were identified using Youden index.

RESULTS

Of the 38 cysts identified on antenatal ultrasound, 24 (63%) persisted postnatally, 8 required surgery (21%) and 4 (11%) were not considered an intra-abdominal cyst postnatally. Ovarian cyst and duplication cyst may have different growth characteristics. In the prediction of cysts persisting postnatally, the area under the ROC curve (AUC) was 0.81 (95% CI, 0.66-0.95). Two cut off values were identified, 37.5 mm (50% sensitivity, specificity 100%, Youden's index 0.50) and 28.5 mm (sensitivity 65%, specificity 85%, Youden's index 0.50). In the prediction of surgery, no optimal diameter was found; AUC was 0.57 (95% CI, 0.34-0.81).

CONCLUSIONS

Maximum antenatal cyst diameter is useful for the prediction of whether a cyst will persist postnatally but not for the prediction of surgery.

Psychological experiences of women with pregnancy termination due to fetal anomalies: a qualitative study from the perspective of women, their spouses, and healthcare providers in Iran

Background

Pregnancy termination due to fetal anomalies has many psychological consequences for women. Providing appropriate and desirable care to this group of women and their families plays an important role in the process of coping with this crisis. The aim of the present study was to explore the psychological experiences of women with pregnancy termination due to fetal anomalies.

Methods

This was a qualitative content analysis study. 40 participants were selected through purposeful sampling with maximum variation and data were collected through in-depth individual interviews, field notes, and analyzed using the conventional qualitative content analysis method simultaneously.

Results

After analyzing the interview transcripts, the psychological experiences of women with pregnancy termination due to fetal anomalies were classified into two main categories: “emotional reactions coinciding with the diagnosis of fetal anomalies” (consisting of two sub-categories of “disbelief and denial of fetal anomalies” and “feelings of sadness and anger”) and “ psychological problems following pregnancy termination” (consisting of two sub-categories of “ feeling helpless, fearful, anxious, and depressed” and “feeling conscience-stricken, and guilty”).

Conclusion

According to findings of the present study, exploring and highlighting the experiences of women with pregnancy termination due to fetal anomalies in the psychological dimension can provide a deeper understanding of the needs of these women for providing optimal care at different times and ultimately promote their psychological health.

Ultrasound 2-D and 3-D diagnosis of Rubinstein-Taybi syndrome in a 21-week-old fetus

Rubinstein-Taybi syndrome is a rare genetic multisystem disorder with an estimated prevalence between 1 per 100,000-125,000 live births. Diagnosis is usually clinical and subsequent to birth. In fact, the rarity of the syndrome and the presence of aspecific morphologic anomalies make prenatal diagnosis challenging. The aim of our work is to analyze ultrasonographic findings, detectable with a combination of 2D and 3D techniques, which may increase the sensitivity of in utero diagnosis of this condition. We report a case of a sonographic prenatal diagnosis of broad and angulated thumbs and halluces and of an abnormal ductus venosus at 21 weeks of gestational age. These findings allowed us to suspect Rubinstein-Taybi syndrome. An accurate ultrasonographic examination may allow a prenatal diagnosis of those syndromes which are usually diagnosed after birth.

Cavum velum interpositum cysts in normal and anomalous fetuses in second trimester of pregnancy: Comparison of its size and prevalence

OBJECTIVE

Cavum veli interpositi (CVI) is a potential space below the splenium of corpus callosum and sometimes presents as a cyst.

MATERIALS AND METHODS

In this prospective cross-sectional study, 360 fetuses with normal second trimester scan and 152 s trimester fetuses with structural abnormalities were included.

RESULTS

The CVI cysts were more common in fetuses with brain anomaly compared to normal fetuses and fetuses with extra-central nervous system (CNS) anomalies (23% vs 18.3% and 18% respectively; p value < 0.01). The mean size of cysts in normal fetuses, fetuses with extra-CNS anomalies and fetuses with brain abnormalities was 4.6 mm, 5.8 mm and 9.2 mm respectively. There was a significant difference between cysts size in normal fetuses and fetuses with brain anomalies (p value < 0.01) and the cut-point was 7.1 mm.

CONCLUSION

The prevalence of CVI cysts is more in fetuses with brain anomaly. Fetuses with a cyst size >7.1 mm need a more detailed brain examination.

Neurodevelopmental Outcome in Infants with Lower Urinary Tract Obstruction Based on Different Degrees of Severity

OBJECTIVE

To determine postnatal neurodevelopmental (ND) outcomes for children with congenital lower urinary tract obstruction (LUTO) based on disease severity.

METHODS

Twenty male infants with LUTO were classified prenatally as Stage 1 (normal amniotic fluid and renal function; n = 5), Stage 2 (signs of obstruction with preserved renal function; n = 13), and Stage 3 (signs of severe renal damage; n = 2). ND status was assessed using the Developmental Profile-3 test in 5 developmental domains (physical, adaptive behavior, social-emotional, cognitive, and communication). Each domain was considered to be delayed if standard scores were 2 or more SD below the mean. ND outcomes were compared between cases with an expected normal renal function (LUTO Stage 1) and those with impaired renal function (LUTO Stages 2 and 3). Results from cases with Stage 2 were also compared to those from Stage 3. ORs were calculated to predict risk for adverse ND outcome for each domain considering prenatal and postnatal factors.

RESULTS

Gestational age (GA) at the diagnosis of LUTO was similar between both groups (Stage 1: 24.85 ± 7.87 vs. Stages 2 and 3: 21.4 ± 4.31 weeks; p = 0.24). Twelve of 15 cases with Stage 2 or 3 underwent vesicoamniotic shunt placement compared to none of Stage 1 fetuses (p < 0.01). No differences in GA at delivery were detected between the groups (37.9 ± 1.6 vs. 35.1 ± 3.6 weeks; p = 0.1). One of the infants in the Stage 2 and 3 groups received a kidney transplant during follow-up. One case (20%) from Stage 1 group required dialysis during the first 6 months of life, and 1 case from Stage 2 to 3 group required it during the first 6 months (p = 1.0), whereas 3 additional cases needed dialysis from 6 to 24 months (p = 0.6). Mean age at Developmental Profile 3 (DP-3) testing was 20.3 ± 12.3 months (Stage 1: 11.2 ± 8.6 vs. Stages 2 and 3: 23.4 ± 13.4 months; p = 0.07). Fifteen of the 20 patients (75%) had no ND delays. Of the 5 patients with ND delays, 4 received dialysis. No differences in ND outcomes between infants with LUTO Stage 1 and those with Stages 2 and 3 were detected except for a trend toward better physical development in Stage 1 (102.6 ± 11.6 vs. 80.7 ± 34.9; p = 0.05). Infants diagnosed with LUTO Stage 3 showed significantly lower adaptive scores than those diagnosed with Stage 2 (Stage 2: 101.9 ± 22.3 vs. Stage 3: 41.5 ± 30.4; p = 0.04) and a nonsignificant trend for lower results in physical (85.8 ± 33.0 vs. 47.5 ± 38.9; p = 0.1) and socio-emotional (94.7 ±17.9 vs. 73.5 ± 13.4; p = 0.1) domains. Infants who received dialysis showed 15-fold increased risk (95% CI 0.89-251) for delayed socio-emotional development (p = 0.06). Diagnosis of fetal renal failure increased the risk for delays in the adaptive domain 30-fold (95% CI 1.29-93.1; p = 0.03). Infants with abnormal renal function had 19 times (95% CI 1.95-292) increased risk for delays in the physical domain (p = 0.03).

CONCLUSIONS

While most patients with LUTO do not exhibiting ND delays, our results support the importance of ND monitoring, especially in severe forms of LUTO, as increased severity of this condition may be associated with poorer ND outcomes.

Ethical and Legal Dilemmas Around Termination of Pregnancy for Severe Fetal Hydrocephalus, Spina Bifida Aperta and Meningomyelocoella

Introduction:

There are many ethical and moral dilemmas regarding the termination of pregnancy(TOP) with severe fetal anomalies.

Aim:

Our aim is to present a case of severe fetal hydrocephalus (HCP), spina bifida aperta and, meningomyelocoella (MMC).

Case report:

A gynecologist examined a 23-year-old patient with vital pregnancy of 24/25 week of gestation (WG) with the anomaly of the fetus. At the Perinatological Medical Advisory Board, a decision was made that the pregnancy should be continued and monitored bearing in mind that pregnancy exceeded the legal framework for TOP. Medical Advisory Board’s ultrasound examination showed the following: severe hydrocephalus (HCP), spina bifida aperta, hyperehogen intestine, pes equinovarus. Via multidisciplinary consultation it was decided to make a delivery with the elective caesarian section (CS) causing as little trauma to the fetus as possible, with 37 WG completed due to the pelvic presentation and fetal anomalies. The patient gave birth via CS to a live female newborn–birth weight 3920 grams, birth length 56 cm, head circumference 48 cm, and Apgar score 8/8. The head was hydrocephalic with spaced suture. There was thoracolumbar defect of spina bifida aperta and meningomyelocele (MMC) 10x12 cm in size. An urgent surgical procedure - the external ventricular derivation of the liquor, and then the successful resection and plastic meningomyelocele was performed by a team of neuro and plastic surgeons. During the fourth postoperative day due to a suspicion of abscess collection and febrility of the mother a relaparotomy is performed and the abscess collection of Retzius space was found. Due to the fall in blood count, blood transfusion in a total dose of 580 ml was given. The patient was discharged on a home treatment as she had a regular general and local status. After the surgery, the condition of the newborn resulted in deterioration, the progression of HCP and dehiscence of head wounds and the thoracolumbar region, in spite of all the measures taken. At that time a decision was made to provide palliative care and this decision was conveyed to the mother. The child had a prolonged apnoeic episode and was not resuscitated. The child died in hospital after surviving for two months postpartum.

Conclusion:

Indication of TOP based on fetal anomalies could be a medical decision but also a personal moral choice of the mother related to legal rules, socio-cultural values and religious beliefs.

Women who received varicella vaccine versus natural infection have different long-term T cell immunity but similar antibody levels

BACKGROUND

Varicella-zoster virus (VZV) infection during pregnancy is associated with serious fetal anomalies. The live-attenuated VZV vaccine was approved in 1995, so many vaccinated women are now of childbearing age. The question of long-term immunity to varicella is critical because breakthrough chickenpox can occur after vaccination.

OBJECTIVE

To compare humoral and T cell immunity between women of childbearing age who were immunized by vaccination or chickenpox disease.

STUDY DESIGN

Non-pregnant females between 18 and 36 years old with a history of VZV immunization (n = 20) or prior chickenpox disease (n = 20) were recruited. IgG antibody titers and T cell responses were measured by flow cytometry-based methods in serum and peripheral blood, respectively.

RESULTS

There were no significant differences in median antibody titers between vaccinated and chickenpox groups (p = 0.34). The chickenpox group had significantly higher levels of VZV antigen-specific CD4 T cells (p = 0.004).

CONCLUSION

Natural infection induced higher VZV-specific T cell immune responses than vaccination.

Prenatal Diagnosis by Whole Exome Sequencing in Fetuses with Ultrasound Abnormalities

Whole-exome sequencing (WES) has been used as a standard of care for postnatal diagnosis in the clinical setting in the past few years for children and adults with undiagnosed disease. Many rare disorders have been diagnosed through WES, which is less expensive than the traditional serial genetic testing where patients had previously spent years on an uninformative diagnostic odyssey. Seeking a diagnosis often entails enduring time consuming, and sometimes invasive procedures which may be associated with medical risks that are stressful for families and impose a heavy burden on the health-care system. However, the use of WES is considered impractical in the prenatal and neonatal testing period because of the technical and computational challenges of performing genomic sequencing from small amounts of genetic material, and the need for faster turnaround time (TAT) than the current 6-8 weeks TAT provided by most clinical labs offering postnatal testing. With the rapidly evolving methods of sequence analysis, there are clinical challenges such as the constantly increasing number of genes being identified which are not yet fully phenotypically characterized, especially when ascertained prenatally or neonatally before all the clinical features may be evident. Despite these challenges, there are many clinical benefits to acquiring genomic information in the prenatal and neonatal period. These include superior prognostic information which allows for prenatal planning of mode of delivery and hospital for delivery and optimized neonatal management. We have developed a clinical WES assay using small amounts of DNA with a TAT of 10 days for use in the prenatal or neonatal setting. This test is used to detect small nucleotide variants and indels in fetuses and neonates with structural abnormalities.

The Experience of Genetic Counselors Working with Patients Facing the Decision of Pregnancy Termination after 24 Weeks Gestation

Prenatal genetic counselors are health care professionals who counsel women making reproductive decisions which include decisions such as terminating pregnancies due to fetal anomalies. Little is known about the experiences and practices of prenatal genetic counselors working with women who have the option of termination after 24 weeks gestation. In this national survey of 168 genetic counselors who have practiced prenatal genetic counseling, we asked about their general practice patterns, including indications for which termination is offered and types of abortion care services that are coordinated by genetic counselors. We report respondents' self-assessments of level of understanding of federal abortion law and abortion procedures. Seventy-six percent of respondents have offered and counseled on termination after 24 weeks and 93% of respondents believe it is the responsibility of the counselor to discuss this option with patients. However, one-third report that they have some or no understanding of the procedures and three-quarters report that they have some or no understanding of federal abortion law. The results of this study provide insight into knowledge and experiences of genetic counselors working with these patients, allowing for improved genetic counselor training and continuing education to provide better guidance and develop more effective means of assisting patients.

Prenatal diagnosis of spina bifida: from intracranial translucency to intrauterine surgery

Accurate and timely prenatal diagnosis of spina bifida (SB) is a major goal of modern antenatal care. Prenatal screening for open SB should be first performed at the time of routine first-trimester ultrasound by examining the posterior fossa for obliteration or non-visualization of the fourth ventricle ("intracranial translucency") and cisterna magna. The second step of screening is the second-trimester anatomy scan, at which time the features of the Chiari type II malformation should be looked for, including ventriculomegaly, scalloping of the frontal bones ("lemon" sign), and backward and caudal displacement of the cerebellar vermis with obliteration of the cisterna magna ("banana" sign). In cases with positive findings, evaluation must include a focused examination of the spine for defects. In cases of closed SB and SB occulta, the cranial and posterior fossa features will not be present as they are not associated with leaking of spinal fluid and resultant hindbrain herniation, highlighting the fact that the spine should be examined thoroughly whenever possible during the second-trimester scan. In tertiary fetal medicine centers, two-dimensional and three-dimensional ultrasound allows an accurate determination of the location, type, extent, and upper level of the spinal defect as well as the presence of associated anomalies. Fetal magnetic resonance imaging should be restricted to candidates for intrauterine surgery as part of the preoperative protocol.

Fetal MRI of the central nervous system: State-of-the-art

Prenatal ultrasonographic (US) examination is considered as the first tool in the assessment of fetal abnormalities. However, several large-scale studies point out that some malformations, in particular central nervous system (CNS) anomalies, are not well characterized through US. Therefore, the actual malformation severity is not always related to prenatal ultrasound (US) findings. Over the past 20 years, ultrafast Magnetic Resonance Imaging (MRI) has progressively increased as a prenatal 3rd level diagnostic technique with a good sensitivity, particularly for the study of fetal CNS malformations. In fact, CNS anomalies are the most common clinical indications for fetal MRI, representing about 80% of the total examinations. This review covers the recent literature on fetal brain MRI, with emphasis on techniques, safety and indications.

Impact of fetal counseling on outcome of antenatal congenital surgical anomalies

AIM

To analyze the impact of counseling on antenatal congenital surgical anomalies (ACSA).

METHODS

Cases presenting with ACSA for fetal counseling and those presenting in post-natal period following diagnosis of ACSA (PACSA) for surgical opinion were analyzed for spectrum, presentation and outcome.

RESULTS

117 cases including ACSA(68);PACSA(49) were analyzed. Gestational age at diagnosis of ACSA;PACSA was 17-37;17-39 weeks (median 24;32 weeks). Diagnoses in ACSA;PACSA included urological (26;31), neurological (10;5), congenital diaphragmatic hernia (CDH)(5;1), gastrointestinal (5;5), lung and chest anomalies (5;1), intraabdominal cysts (4;1), abdominal wall defects (4;0), tumors (3;3), limb anomaly (1;1), esophageal atresia (1;1), conjoint twins (1;0), hepatomegaly (1;0), and major cardiac anomalies (2;0). Two antenatal interventions were done for ACSA; vesicoamniotic shunt and amnioinfusion for oligohydramnios. 17;24 ACSA;PACSA required early surgical intervention in post-natal period. Nine ACSA underwent medical termination of pregnancy and 4 had intrauterine demise. Nine ACSA babies died including two CDH, one gastroschisis, one duodenal atresia, one conjoint twins, one megacystitis with motility disorder and three posterior urethral valves. All PACSA babies survived.

CONCLUSION

Fetal counseling for CSA portrays true outcome of ACSA with 32.3% (22/68) mortality versus 0% for PACSA due to selection bias. However, fetal counseling ensures optimal perinatal care.

A Study on The Incidence of Neural Tube Defects in A Tertiary Care Hospital Over A Period of Five Years

INTRODUCTION

Several congenital malformations affect developing fetuses, among which Neural tube defect (NTD) is most common. Folic acid supplementation brought decline in the incidence of NTDs. The present study aims at finding the incidence of NTDs in a tertiary care hospital and compares the results with the similar Indian studies published earlier.

MATERIALS AND METHODS

The study was done at Chettinad Hospital & Research Institute (CHRI), Kelambakkam. The total number of deliveries was recorded for a period of five years from 2009 to 2013. Fetuses which were still born with neural defect were collected and observed in detail externally for the sex, type of NTD and other associated anomalies. Indian studies published between 1987 and 2014 reporting the incidence of NTDs among the births occurred were retrieved from the Internet and their various observations were used for comparison.

RESULTS

The number of deliveries conducted between 2009 and 2013 at CHRI was 3220. Of these, babies born with NTDs were nine (5 males and 4 females). The incidence of fetuses with meroanencephaly, holoanencephaly, craniorachischisis, encephalocele and myelocele were 0.62, 0.62, 0.93, 0.31 and 0.31 per 1000 births respectively. Overall incidence of NTDs in the present study was 2.79/1000 births. Fetuses with NTDs also had the following anomalies - Club foot, cleft lip and palate and exomphalos.

CONCLUSION

Comparing the results with the previous studies it is clearly evident that the incidence of NTDs have significantly reduced from 11.42/1000 births to 2.79/1000 births. In most of the previous studies NTDs had a female preponderance whereas present study has a male preponderance.In older studies, spina bifida was the most common NTDs followed by anencephaly. But in the present study anencephaly was the common NTD than spina bifida. Incidence of NTDs has reduced due to various reasons like prenatal screening for fetal anomalies and folic acid supplementation.

Arkansas fetal diagnosis and management: identifying and coordinating care for anomalous fetuses

OBJECTIVE

Describe a novel system of coordinating the identification and management of fetal anomalies in a rural state, where there is a large proportion of impoverished and Medicaid eligible patients, and centralization of the majority of tertiary care resources.

METHODS

The Arkansas Fetal Diagnosis and Management program was initiated to coordinate the care of anomalous fetuses. Data from the beginning of the program (2009) to 2013 was collected and analyzed. The data is reported in a descriptive fashion, to report the outcomes of this program. The specific type and number of anomalies diagnosed and managed were tabulated and analyzed.

RESULTS

From 2009 to 2013, data from 1300 pregnancies was collected. From 2009 to 2013, there were 7.9%, 10.9%, 15.0%, 18.6%, and 22.3% of ultrasound referrals with fetal anomalies. The anomalies were grouped by physiologic system, and despite the total numbers increasing each year, the frequency and distribution of anomalies remained constant.

CONCLUSIONS

The Arkansas Fetal Diagnosis and Management Program streamlined the coordination of care for pregnancies affected by anomalous fetuses.

Understanding the Limitations of Circulating Cell Free Fetal DNA: An Example of Two Unique Cases

Circulating cell free fetal DNA (cffDNA) is an effective screening modality for fetal aneuploidy. We report two cases of false positive results. The first case involves a female, with self-reported Down syndrome. CffDNA returned positive for trisomy 18 leading to a maternal diagnosis of mosaicism chromosome 18 with normal fetal karyotype. The second case involves a patient with an anomalous fetal ultrasound and cffDNA positive for trisomy 13. Amniocentesis demonstrated a chromosome 8p duplication/deletion. False positive cffDNA may arise in clinical scenarios where diagnostic testing is clearly indicated. Practitioners should recognize the limitations of cffDNA.

Prenatal diagnosis and outcome of right aortic arch without significant intracardiac anomaly

BACKGROUND

Right aortic arch (RAA) is usually associated with the presence of a significant congenital heart disease, usually a conotruncal defect, which determines the postnatal outcome. In the absence of such cardiac defects, the significance of RAA has not been determined. The aims of this study were to evaluate the significance of recognizing RAA in fetuses with normal or near normal intracardiac anatomy and to determine which associations may be present.

METHODS

A retrospective study was completed of all fetuses diagnosed with RAA with normal or near normal intracardiac anatomy between 1999 and 2011. The aim was to evaluate the presence of RAA with complete ultrasonic evaluation using two-dimensional imaging complemented by the Doppler color flow technique, paying particular attention to the three-vessel and tracheal view. We compared the prenatal findings with the postnatal outcomes and management of this cohort of fetuses.

RESULTS

Among 16,450 fetal echocardiograms, 58 fetuses (0.35%) were diagnosed with RAA with normal or near normal intracardiac anatomy. Gestational age at diagnosis ranged from 19 to 34 weeks (mean, 23 weeks). Isolated RAAs were found in 50 fetuses, and double aortic arches (DAAs) were recognized in eight other cases. The postnatal cohort consisted of 44 newborns with RAAs and eight with DAAs (two were lost to follow-up, and four pregnancies were terminated). Postnatal echocardiography confirmed the prenatal diagnosis of RAA in 41 of 45 children, and four were found to have DAAs. Three of seven fetuses diagnosed prenatally as having DAAs were found to have only RAAs. Fourteen fetuses underwent karyotyping; two had 22q11 deletion and two had 47xxy. Eleven infants (21%) had respiratory symptoms, eight with DAAs, one with RAA, mirror-image head and neck vessels, and two with RAAs and aberrant left subclavian arteries. Surgery was indicated in all symptomatic patients except one, whose symptoms resolved. One asymptomatic patient underwent operation for significant compression of the trachea.

CONCLUSIONS

RAA on fetal ultrasonography may indicate vascular and chromosomal abnormalities that may complicate postnatal management. When RAA is identified, fetal karyotype analysis (including the integrity of chromosome 22) is warranted. RAA may herald an occult DAA and may be a clue to a tight vascular ring. Hence, it seems essential to conduct a careful postnatal evaluation of fetuses with RAAs on prenatal ultrasound.

Benefits and risks of MRI in pregnancy

Ultrasound remains the modality of choice in imaging the fetus due to its availability, safety, and low cost. With advances in technology, however, magnetic resonance imaging (MRI) has become an important adjuvant in the evaluation of the fetus. MRI is not limited by fetal lie, oligohydramnios, overlying bone, or obesity. MRI can image the fetus in any plane, providing a large field of view of the fetus and placenta with excellent soft tissue resolution of the brain, airway, lungs, and abdomen. Advanced techniques are being developed that provide volumetric data, spectroscopy, and functional images. MRI has its own set of challenges with a lack of consensus regarding its utility and safety. Artifact from the moving fetus and breathing mother limits the sequences available. While there is currently no evidence that fetal MRI produces harmful effects, long-term safety regarding radiofrequency fields and the loud acoustic environment continues to be studied. In this review, the benefits and potential risks of fetal MRI will be discussed.

The use of obstetrical ultrasound in the obese gravida

Obesity is an epidemic in the United States, especially among the pregnant population. Obesity is responsible for an increase in fetal anomalies and adverse outcome of both mother and fetus. Due to difficulty in penetrating to the depth of the uterus, the ultrasound image in obese patients is inadequate, fuzzy, and high in artifacts. Hence, obese patients often require multiple scans as well as special scanning techniques just to get borderline image quality. These techniques and the data regarding quality and frequency of scans for the obese pregnant population are discussed in this paper.

Contemporary management of fibroids in pregnancy

Uterine fibroids are a very common finding in women of reproductive age. The majority of fibroids do not change their size during pregnancy, but one-third may grow in the first trimester. Although the data are conflicting and most women with fibroids have uneventful pregnancies, the weight of evidence in the literature suggests that uterine fibroids are associated with an increased rate of spontaneous miscarriage, preterm labor, placenta abruption, malpresentation, labor dystocia, cesarean delivery, and postpartum hemorrhage.

First trimester ultrasound: current approaches and practical pitfalls

Revolutionary technological improvements and high-frequency transvaginal scanning have enabled the resolution of ultrasound imaging in the first trimester to increase such that detailed early fetal development can now be well visualized. This investment in imaging technology has enabled not only normal embryonic development but also chromosomal abnormalities and structural anomalies to be more easily and accurately diagnosed before the second trimester. This article is intended to help radiologists in the interpretation and clinical application of normal and abnormal first trimester ultrasound findings in early pregnancy. We review the current literature and applications and interpretations of first trimester ultrasound.
