CHD is known to be associated with increased risk for neurodevelopmental disorders. The combination of CHD with neurodevelopmental disorders and/or extra-cardiac anomalies increases the chance for an underlying genetic diagnosis. Over the last 15 years, there has been a dramatic increase in the use of broad-scale genetic testing. We sought to determine if neurodevelopmental disorders in children with single-ventricle CHD born prior to the genetic testing revolution are associated with genetic diagnosis.
Methods:
We identified 74 5–12-year-old patients with single-ventricle CHD post-Fontan procedure. We retrospectively evaluated genetic testing performed and neurodevelopmental status of these patients.
Results:
In this cohort, there was an overall higher rate of neurodevelopmental disorders (80%) compared to the literature (50%). More of the younger (5–7-year-old) patients were seen by genetic counsellors compared to the older (8–12-year-old) cohort (46% versus 19% p value = 0.01). In the younger cohort, the average age of initial consultation was 7.7 days compared to 251 days in the older cohort. The overall rate of achieving a molecular diagnosis was 12% and 8% in the younger and older cohorts, respectively; however, the vast majority of did not have broad genetic testing.
Conclusion:
The minority of patients in our cohort achieved a genetic diagnosis. Given a large increase in the number of genes associated with monogenic CHD and neurodevelopmental disorders in the last decade, comprehensive testing and consultation with clinical genetics should be considered in this age range, since current testing standards did not exist during their infancy.
We aimed to investigate child mortality, perinatal morbidities and congenital anomalies born by women with substance misuse during or before pregnancy (DP or BP).
Methods
Taiwan Birth Registration from 2004 to 2014 linking Integrated Illicit Drug Databases used to include substance misuse participates. Children born by mothers convicted of substance misuse DP or BP were the substance-exposed cohort. Two substance-unexposed comparison cohorts were established: one comparison cohort selected newborns from the rest of the population on a ratio of 1:1 and exact matched by the child’s gender, child’s birth year, mother’s birth year and child’s first use of the health insurance card; another comparison cohort matched newborns from exposed and unexposed mothers by their propensity scores calculated from logistic regression.
Results
The exposure group included 1776 DP, 1776 BP and 3552 unexposed individuals in exact-matched cohorts. A fourfold increased risk of deaths in children born by mothers exposed to substance during pregnancy was found compared to unexposed group (hazard ratio [HR] = 4.54, 95% confidence interval (CI): 2.07–9.97]. Further multivariate Cox regression models with adjustments and propensity matching substantially attenuated HRs on mortality in the substance-exposed cohort (aHR = 1.62, 95% CI: 1.10–2.39). Raised risks of perinatal morbidities and congenital anomalies were also found.
Conclusions
Increased risks of child mortality, perinatal morbidities or congenital anomalies were found in women with substance use during pregnancy. From estimates before and after adjustments, our results showed that having outpatient visits or medical utilizations during pregnancy were associated with substantially attenuated HRs on mortality in the substance-exposed cohort. Therefore, the excess mortality risk might be partially explained by the lack of relevant antenatal clinical care. Our finding may suggest that the importance of early identification, specific abstinence program and access to appropriate antenatal care might be helpful in reducing newborn mortality. Adequate prevention policies may be formulated.
In monochorionic monoamniotic twin pregnancies, two fetuses share a single placenta and a single amniotic cavity. This unique anatomic configuration, although rare, puts them at high risk for a number of complications including structural anomalies, twin-twin transfusion syndrome, selective intra-uterine growth restriction and cord accidents. Early diagnosis and patient counselling are therefore crucial. Level 1 evidence on the optimal management of monoamniotic twins is lacking, but observational studies provide some guidance for best practice. In uncomplicated monoamniotic twins, after viability, fetal mortality is less than 5% if close surveillance is initiated. This can be done in either an inpatient or outpatient setting. If all goes well, monoamniotic twins should be delivered from 33 weeks’ gestation as, at that timepoint, the risk of in utero death is larger than the risk of (non-respiratory) neonatal complications.
This review study examines the cases of improving the therapeutic skills of therapists and areas of counseling and the important cases that midwives have to provide services and manage conditions if Diagnosis of an abnormal fetus requires attention.
Objectives
We aim to find the best ways of counseling for helping parents with diagnosed abnormal fetuses
Methods
A search conducted by using the keywords congenital anomalies, psychological counseling, prenatal counseling in PubMed, science direct, clinical key and Google scholar search engine. after screening, the complete data of 20 articles were included in this review article.
Results
The results showed that pregnancy counseling with abnormal fetuses includes medical and psychological counseling. In medical counseling, knowledge of the types of tests and their interpretation is important, and prenatal screening training programs for health care providers should be revised based on their educational needs. In psychological counseling, to meet the needs of a changing population of clients Midwives in the context of the wider healthcare system need accurate knowledge of religious beliefs and cultural contexts of their clients in order to take the best approach to relevant care. The occurrence of a diagnosis of congenital anomaly during transmission to parents adds to the accumulation of stress-related events that may increase the risk of developing psychological symptoms in the early stages after diagnosis.
Conclusions
Considering the different cultures of different countries of the world, midwifery counseling skills play an important part in the diagnostic and therapeutic process. Therefore, creating extraordinary educational programs on university education is needed for midwives.
To explore the lived experience of delivering or receiving news about an unborn or newborn child having a condition associated with a learning disability in order to inform the development of a training intervention for healthcare professionals. We refer to this news as different news.
Background:
How healthcare professionals deliver different news to parents affects the way they adjust to the situation, the wellbeing of their child and their ongoing engagement with services. This is the first study that examined the lived experience of delivering and receiving different news, in order to inform the development of training for healthcare professionals using the Theoretical Domains Framework version 2.
Method:
We conducted qualitative interviews with a purposive sample of 9 different parents with the lived experience of receiving different news and 12 healthcare professionals who delivered different news. It was through these descriptions of the lived experience that barriers and facilitators to effectively delivering different news were identified to inform the training programme. Data analysis was guided by Theoretical Domains Framework version 2 to identify these barriers and facilitators as well as the content of a training intervention.
Findings:
Receiving different news had a significant impact on parents’ emotional and mental wellbeing. They remembered how professionals described their child, the quality of care and emotional support they received. The process had a significant impact on the parent–child relationship and the relationship between the family and healthcare professionals.
Delivering different news was challenging for some healthcare professionals due to lack of training. Future training informed by parents’ experiences should equip professionals to demonstrate empathy, compassion, provide a balanced description of conditions and make referrals for further care and support. This can minimise the negative psychological impact of the news, maximise psychological wellbeing of families and reduce the burden on primary care services.
To determine clinical consensus and non-consensus in regard to evidence-based statements about feeding infants with complex CHD, with a focus on human milk. Areas of non-consensus may indicate discrepancies between research findings and practice, with consequent variation in feeding management.
Materials and Methods:
A modified Delphi survey validated key feeding topics (round 1), and determined consensus on evidence-based statements (rounds 2 and 3). Patients (n=25) were an interdisciplinary group of clinical experts from across the United States of America. Descriptive analysis used SPSS Statistics (Version 26.0). Thematic analysis of qualitative data provided context for quantitative data.
Results:
Round 1 generated 5 key topics (human milk, developing oral feeding skills, clinical feeding practice, growth failure, and parental concern about feeding) and 206 evidence-based statements. The final results included 110 (53.4%) statements of consensus and 96 (46.6%) statements of non-consensus. The 10 statements of greatest consensus strongly supported human milk as the preferred nutrition for infants with complex CHD. Areas of non-consensus included the adequacy of human milk to support growth, need for fortification, safety, and feasibility of direct breastfeeding, issues related to tube feeding, and prevention and treatment of growth failure.
Conclusions:
The results demonstrate clinical consensus about the importance of human milk, but reveal a need for best practices in managing a human milk diet for infants with complex CHD. Areas of non-consensus may lead to clinical practice variation. A sensitive approach to these topics is needed to support family caregivers in navigating feeding concerns.
This chapter summarizes the fetal stem cell transplantation and reviews the current status of fetal tissue engineering, along with other relevant information. Tissue engineering is almost universally hampered by certain predictable complications, namely vascularization and growth limitations, differentiation and function restraints, etc. A variety of sites, in addition to the fetus itself, can be sources of fetal cells in procurable amounts compatible with tissue engineering processing. At this time, proven viable sources have included the amniotic fluid, placenta, Wharton's jelly, and umbilical cord blood. Treatment of many congenital anomalies is hindered by the scarce availability of normal tissues or organs especially at birth. The ever present severe donor shortage that hampers practically all forms of transplantation is even more pronounced during the neonatal period. Fetal tissue engineering has emerged as a viable option to overcome these obstacles, posing a new alternative for the treatment of these anomalies.
The usefulness of monozygotic (MZ) twins for studying the efficacy of different face lift techniques is described. The data suggest that no particular procedure out of four under consideration is superior to any other. Next, reviews of recent twin studies of congenital anomalies, personality traits and coital orgasmic infrequency, and physical activity participation are presented. Finally, timely topics of public interest are also described. They include a rare birth consequence of artificial reproductive technology, an update on state legislation regarding parents' rights to decide the classroom placement of their young twins, and medical malpractice lawsuits involving premature twins.
A vascular ring refers to encirclement of the trachea and oesophagus by an abnormal combination of derivatives of the aortic arch system. These malformations can cause variable degrees of compression of the oesophagus, trachea or both. Symptoms can range from no effect to severe stridor, dyspnoea and/or dysphagia.
Method and results:
This study presents a case series of six patients treated over a six-year period (2003–2009), illustrating the features of four different types of vascular ring; these types are discussed in detail. The clinical presentation, radiology, and microlaryngoscopy and bronchoscopy findings are also discussed.
Conclusion:
The management of children with vascular rings requires a high index of clinical suspicion to ensure prompt diagnosis. As many of these children present with airway symptoms, the paediatric otolaryngologist plays a key role in identifying and assessing their anatomical anomalies.
This chapter discusses the implications of assisted reproductive technology (ART) in formation of congenital anomalies. Examples of congenital anomalies with ART include anencephaly, spina bifida, cardiovascular defects, orofacial clefts, and alimentary tract atresia. Imprinting disorders examined with regard to in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) conception are Angelman syndrome and Beckwith-Wiedemann syndrome, and recent reports have suggested a higher risk of these specific disorders after ART. Women receiving IVF treatment face a twentyfold increased risk of twins and a 400-fold increased risk of higher order births. Preimplantation genetic diagnosis (PGD) is ever evolving with fluorescent in situ hybridization (FISH) for sexing, aneuploidy screening, and structural chromosomal abnormalities and fluorescent and multiplex PCR as the most recent developments for monogenic diseases. Infertility itself is likely to be an important factor in congenital anomalies after ART.

This chapter explores the maternal and fetal complications, advances in prenatal diagnosis, and management of complications unique to multiple gestations. Tidal volume and oxygen consumption in multiple gestations are increased, as is the normal alkalosis seen in singleton pregnancy. Hypertensive disorders increase by at least twofold in twin gestations. Hemorrhagic complications occur more frequently with twins. Growth of singletons and twins is comparable until 27 weeks gestation. The uterus accommodates the larger volume imposed by twins by overdistension, and beyond a certain limit, premature labor can result. Preterm deliveries (less than 37 weeks' gestation) occurred in 10.6% of singleton pregnancies against a phenomenal rate of 61.2% of live births in multiple gestations. Diagnosis of multiple gestations, establishing chorionicity, identifying anomalies, foreseeing possible maternal and fetal complications, prevention and treatment of preterm labor, and management of growth restriction are some of the areas of medicolegal concerns in multiple gestations.
A 3-month-old infant developed signs of cardiac failure, which was initially attributed to cardiomyopathy. At 8 months, further investigations showed evidence of myocardial ischaemia with reversal of the flow of blood in the left coronary artery, which received no demonstrable inflow from the aorta. An anomalous connection of this artery with the pulmonary trunk was diagnosed but, at surgery, it was found that the arterial orifice was completely atretic, although the main stem was of normal size. A left internal thoracic arterial graft to the anterior descending coronary artery was performed, but he died on the third day after the operation. Postmortem examination showed a small dimple within the aorta at the site of the orificial atresia, extensive myocardial infarction, and two zones of myocardial bridging of the anterior descending coronary artery. We discuss the relationship of coronary orificial atresia with single coronary artery. Although they are related, they typically have different and contrasting clinical presentations. The possible role of the myocardial bridging is also considered.
The authors have analysed the frequency and structure of congenital anomalies in children born in the Pomeranian district in the period from 01.07.1997 to 31.12.1998. Among a total of 28.361 births in that area, 748 (2.64%) were affected by congenital anomalies. Among 28.361 births, 620 (2.18%) were from multiple pregnancies. 23 (3.71%) among births from multiple pregnancies were affected by congenital malformations. The prevalence rate of inborn anomalies in births from multiple pregnancy in our area were higher (3.71%) in comparison to births from singleton pregnancy (2.61%). It implies that children born from multiple pregnancy are at higher risk of developing congenital anomalies.
Rates of congenital anomalies of the cardiovascular system were compared between twins and singletons in a population-based study in Northern Ireland during the period 1974-1978. Multiple sources of ascertainment were used. As in previous studies, the rate of anomalies of the cardiovascular system in twins (91.0/10,000) was higher than the rate in singletons (66.4/10,000). The excess was confined to twins from pairs of like sex and, in the main, anomalies of the circulatory system other than of the heart itself were involved. Problems in the interpretation of this excess are discussed. No twins were concordant for congenital cardiovascular anomalies of any type.
Data are presented from a large-scale population-based study in Northern Ireland, in which multiple sources of ascertainment were used. As found in other studies, the overall prevalence at birth of congenital anomalies amogst twins (285.4/10,000) was somewhat higher than the rate amongst singletons (241.8/10,000). Unlike in other studies, however, the rate amongst twins of like sex (287.8/10,000) was not markedly higher than that amongst twins of unlike sex (252.3/10,000). Problems of comparison between series are discussed.
A statistical model was developed to determine the likelihood of a twin kinship, that is, the offspring of a pair of monozygotic or dizygotic twins under three types of inheritance: sporadic, single locus fetal genetic, and single locus maternal genetic. Samples of 8,000 kinships were simulated for a discrete trait under various hypotheses, and the likelihood determined for each type of etiology. The results indicated that the pedigree analysis procedures formulated here could efficiently detect sporadic or single locus effects with a power approaching 100%, although the parameter estimates obtained were slightly biased. Further analyses revealed that the type of pedigree analysis formulated in this study was found to have equivalent power for equal or unequal frequencies of kinships by the sex and zygosity of the twin parent. It was suggested that further studies be carried out that included the twins and spouses in the likelihood equations, as well as tests of more sophisticated models.
Problems of ascertainment bedevil the investigation of the etiology of congenital anomalies in singletons and in multiple births by epidemiological methods. It is shown that the definition of the population of affected births is ambiguous and that the problem of tracing etiology is complicated by the systematic way in which anomalies may be missed at birth. The available methods of dealing with problems of ascertainment are reviewed. Methods of adjusting for possible bias of ascertainment of affected births, by fitting statistical models to data from several sources, have been employed in some previous studies. In these methods, it is assumed that there are no errors of diagnosis or of recording. However, it is shown that there may be discrepancies in recorded diagnoses between sources, rendering this assumption untenable. In these methods, it is also assumed that the model which is the best fit to the data on the ascertained cases in also the best model for the cases which were not ascertained. This assumption is tested indirectly in a retrospective analysis of data from Aberdeen and Belfast collected concurrently through routine recording systems. It is demonstrated that there was a social process in ascertainment which renders the methods of adjusting for bias of ascertainment at best very complicated and at worst inapplicable.
