Abstract
The ventral body wall (VBW) that encloses the thoracic and abdominal cavities arises by extensive cell movements and morphogenetic changes during embryonic development. These morphogenetic processes include embryonic folding generating the primary body wall; the initial ventral cover of the embryo, followed by directed mesodermal cell migrations, contributing to the secondary body wall. Clinical anomalies in VBW development affect approximately 1 in 3000 live births. However, the cell interactions and critical cellular behaviors that control VBW development remain little understood. Here, we describe the embryonic origins of the VBW, the cellular and morphogenetic processes, and key genes, that are essential for VBW development. We also provide a clinical overview of VBW anomalies, together with environmental and genetic influences, and discuss the insight gained from over 70 mouse models that exhibit VBW defects, and their relevance, with respect to human pathology. In doing so we propose a phenotypic framework for researchers in the field which takes into account the clinical picture. We also highlight cases where there is a current paucity of mouse models for particular clinical defects and key gaps in knowledge about embryonic VBW development that need to be addressed to further understand mechanisms of human VBW pathologies.

Abstract
OBJECTIVE Congenital heart diseases (CHD) are the most frequently associated anomalies with anorectal malformations (ARM). Nevertheless, many specific aspects of CHD in ARM patients have yet to be studied. The aims of this study were to evaluate the prevalence and distribution of CHD in neonates-infants with ARM, and to explore whether the severity of ARM, and the presence of VACTERL association, had an impact on CHD rate, severity, and timing at first cardiac surgery. STUDY DESIGN All consecutive newborn-infants with ARM managed in our tertiary center (January-1999; December-2021) were collected from a prospective database and retrospectively analyzed. Prevalence and distribution of CHD in ARM patients were assessed. Patients were divided into groups depending on ARM severity and presence of VACTERL association. Pairwise comparison for CHD prevalence, severity, and timing at first cardiac surgery was performed between groups. RESULTS Of 396 ARM patients identified, those with severe ARM showed a higher number of overall CHD compared to patients with non-severe ARM (36.7 % vs. 25.2 %, p = 0.032). VACTERL + patients had a significantly higher prevalence of CHD (73.4 % vs. 16.4 %; p <0.001) and major CHD (51.7 % vs. 26.9 %; p = 0.008) when compared with VACTERL-patients. Furthermore, VACTERL + patients underwent first cardiac surgery at a significantly younger age than VACTERL-patients (5.2 ± 15.2 months vs. 11.9 ± 6.3, p = 0.039). CONCLUSIONS Patients with severe ARM had a higher number of CHD compared to patients with non-severe ARM. VATERL + patients had significantly more CHD and more severe CHD than VACTERL-patients. Early screening for CHD is strongly recommended in all newborns diagnosed with ARM before surgery. LEVEL OF EVIDENCE III retrospective comparative study.

Abstract
VACTERL association is defined as the nonrandom co-occurrence of a minimum of three of the following six key components: Vertebral anomalies, Anal atresia, Cardiac malformations, Tracheo-Esophageal fistula, Renal anomalies, and Limb abnormalities. Patients presenting with two components may also belong in the same spectrum. Additional components have been associated with VACTERL defects, including single umbilical artery, tethered spinal cord (TSC), and genital malformations. We observed a significant proportion of patients with bladder dysfunction (often called neurogenic bladder in the medical record) when reviewing a cohort of patients with VACTERL defects at our clinical center. Our finding calls attention to bladder dysfunction as an additional VACTERL phenotypic component. The prevalence of bladder dysfunction is greatest in those with genital anomalies, anorectal malformations, sacral dysplasia, renal anomalies, and TSC. We propose that patients with two or more VACTERL malformations be monitored for symptoms of bladder dysfunction if one or more of the identified risk factors are present until the achievement of urinary continence.

Abstract
BACKGROUND The relationship between maternal age (MA) and birth defects (BD) has been extensively studied while much less research, mostly with discordant results, has focused on the risk of paternal age (PA) for BD. Furthermore, no consensus has been reached on the best way to control the association of PA with MA. OBJECTIVES The aim of the study was to evaluate the risk of PA increase, at 1-year intervals, for selected BD, especially controlling for the confounding effect of MA. METHODS The sample comprised of 27,944 liveborns presenting 1 of 18 selected isolated BD. Conditional logistic regressions were applied to evaluate the risk of advanced PA and its yearly increase, adjusting by MA and other variables. RESULTS Of the 18 analyzed BD, only the risk for preaxial polydactyly (PreP) showed a significant association with increasing PA, while advanced MA was of low risk. For esophageal and anal atresia, associations with both PA and MA increases were observed. CONCLUSIONS Results support the hypothesis of advanced PA as a risk factor for PreP and helps clarify the so far unexplained nonrandom association between this defect and Down syndrome.

Abstract
Background: VACTERL association is a widely known congenital malformation that includes vertebral, anal, cardiac, tracheoesophageal, renal, and limb anomalies. Patients with VACTERL and hydrocephalus appear to form a distinct group, both genetically and phenotypically, and their condition has been called VACTERL-H syndrome. Most cases of VACTERL-H have been reported postnatally, as VACTER-H syndrome is difficult to diagnose prenatally. Case Presentation: Here, we report a case of VACTERL-H syndrome in a dichorionic and diamniotic twin diagnosed prenatally by ultrasonography and confirmed postnatally by three-dimensional computed tomography (3D CT). A 34-year-old multiparous female was referred to our institution at 31 + 3 weeks gestation for suspected fetal ventriculomegaly. Detailed examinations using two-dimensional and Doppler ultrasounds revealed hydrocephalus, bilateral dysplastic upper arms, radial aplasia, unilateral pulmonary agenesis, dextrocardia with right atrial enlargement, a unilateral hypoplastic ectopic kidney, a single umbilical artery, a tracheoesophageal fistula with a small stomach, polyhydramnios, and anal atresia. Findings from the postnatal 3D CT aligned with the prenatal diagnosis, showing upper-limb agenesis, dextrocardia with pulmonary hypoplasia, tracheoesophageal fistula, imperforate anus, and colon dilatation. The affected 1390-g male twin had an unaffected 1890-g female twin sister and a healthy 6-year-old brother. Conclusions: Upon encountering fetuses with multiple anomalies, including ventriculomegaly, a small stomach with polyhydramnios, an abnormally positioned heart, and upper-limb abnormalities, clinicians should perform systematic ultrasonographic examinations to detect associated anomalies and be aware of VACTERL-H syndrome.

Abstract
Many infants with anotia or microtia (A/M) have co-occurring birth defects, although few receive syndromic diagnoses in the perinatal period. Evaluation of co-occurring birth defects in children with A/M could identify patterns indicative of undiagnosed/unrecognized syndromes. We obtained information on co-occurring birth defects among infants with A/M for delivery years 1999-2014 from the Texas Birth Defects Registry. We calculated observed-to-expected ratios (OER) to identify birth defect combinations that occurred more often than expected by chance. We excluded children diagnosed with genetic or chromosomal syndromes from analyses. Birth defects and syndromes/associations diagnosed ≤1 year of age were considered. We identified 1310 infants with non-syndromic A/M, of whom 38% (N = 492) were diagnosed with co-occurring major defects. Top combinations included: hydrocephalus, ventricular septal defect, and spinal anomalies (OER 58.4); microphthalmia and anomalies of the aorta (OER 55.4); and cleft lip with or without cleft palate and rib or sternum anomalies (OER 32.8). Some combinations observed in our study may represent undiagnosed/atypical presentations of known A/M associations or syndromes, or novel syndromes yet to be described in the literature. Careful evaluation of infants with multiple birth defects including A/M is warranted to identify individuals with potential genetic or chromosomal syndromes.

Abstract
Anorectal malformations occur in 1 in 3000 to 5000 children, and present with a marked variety in type and severity. Most of the malformations are diagnosed in the early neonatal period, as an antenatal diagnosis remains relatively elusive. Following diagnosis, an accurate assessment and focused management is crucial to reduce the potential for morbidity and mortality. This review focuses on the investigation and management of newborns with anorectal malformations, and the introduction of novel assessment tools for the more complex malformation types.

Abstract
BACKGROUND Congenital multisystemic lesions with co-occurrence of non-random malformations, such as VACTERL-H or MURCS association, often pose serious threads to the newborn and still constitute an antenatal diagnostic dilemma. CASE REPORT A malformed fetus with VACTERL-H association at 20 gestational weeks had a skin-covered neural tube defect (NTD) of the lower cervical spine, concomitant hydrocephalus, as well as unilateral multicystic dysplastic kidney and the suspicion of mullerian duct anomaly as potentially assigned to MURCS association. DISCUSSION/CONCLUSION We were able to demonstrate how well-defined, standardized volumetric reconstruction of diagnostic views displaying fetal pathology in utero might aid early and precise diagnosis of multi-organ malformations. Application of modern diagnostic imaging tools is helpful in delineation of the most likely diagnoses (VACTERL-H vs. MURCS) as further specified during detailed pathologic work-up and might consequently facilitate individually tailored interdisciplinary counseling, as in the case presented here.

Abstract
Pleiotropy is defined as the phenomenon of a single gene locus influencing two or more distinct phenotypic traits. However, nicotinamide adenine dinucleotide (NAD+) deficiency through diet alone can cause multiple or single malformations in mice. Additionally, humans with decreased NAD+ production due to changes in pathway genes display similar malformations. Here, I hypothesize NAD+ deficiency as a pleiotropic mechanism for multiple malformation conditions, including limb-body wall complex (LBWC), pentalogy of Cantrell (POC), omphalocele-exstrophy-imperforate anus-spinal defects (OEIS) complex, vertebral-anal-cardiac-tracheoesophageal fistula-renal-limb (VACTERL) association (hereafter VACTERL), oculoauriculovertebral spectrum (OAVS), Mullerian duct aplasia-renal anomalies-cervicothoracic somite dysplasia (MURCS), sirenomelia, and urorectal septum malformation (URSM) sequence, along with miscarriages and other forms of congenital malformation. The term Congenital NAD Deficiency Disorder (CNDD) could be considered for patients with these malformations; however, it is important to emphasize there have been no confirmatory experimental studies in humans to prove this hypothesis. In addition, these multiple malformation conditions should not be considered individual entities for the following reasons: First, there is no uniform consensus of clinical diagnostic criteria and all of them fail to capture cases with partial expression of the phenotype. Second, reports of individuals consistently show overlapping features with other reported conditions in this group. Finally, what is currently defined as VACTERL is what I would refer to as a default label when more striking features such as body wall defects, caudal dysgenesis, or cloacal exstrophy are not present.

Abstract
OBJECTIVE This study aims to quantify mortality rates and hospital lengths of stay (LOS) in neonates with esophageal atresia and tracheoesophageal fistula (EA/TEF), and to characterize the effects of birth weight (BW) and associated congenital anomalies upon these. METHODS Data regarding patients with EA/TEF were prospectively collected (2013-2019) at 298 North American centers. The primary outcome was mortality and secondary outcome was LOS. Risk factors affecting mortality and LOS were assessed. RESULTS EA/TEF was diagnosed in 3290 infants with a median BW of 2476 g (IQR 1897,2970). In-hospital mortality was 12.7%. Mortality was inversely correlated with BW. After adjustment, the risk of mortality decreased by approximately 11% with every 100 g increase in BW. A significant congenital anomaly other than EA/TEF was diagnosed in 37.9% of patients. Risk of mortality increased in patients with associated congenital anomalies, most notably in those with a severe cardiac anomaly. Lower BW was associated with an increased mean LOS among survivors. Similar to mortality risk, additional anomalies were associated with prolonged LOS. CONCLUSIONS This study demonstrates an in-hospital mortality of over 10%. Both increased mortality and prolonged LOS are highly associated with lower birth weight and the presence of concomitant congenital anomalies.

Abstract
The spectrum of disorders of sexual development includes anatomical abnormalities of the external genitalia, the phenotypic variability of which and the underlying causes are numerous. However, female aphallia and ectopia of the labium majorum appear to be some of the rarest forms of external genitalia malformations. Aphallia is mostly described in males with a frequency of less than one per 40 000 male newborns. Although syndromic forms of aphallia in females have been reported, for example, in Robinow, CHARGE, and Prader-Willi syndrome, reports of isolated female aphallia are meager. Here, we describe the first case of isolated agenesis of the clitoris with an ectopic labium majorum and review the literature of this uncommon malformation and its potential dysmorphogenetic mechanism. We emphasize the need for a routine exhaustive physical examination to identify and characterize this unusual malformation correctly so that families can be appropriately counseled as to cause and potential complications.

Abstract
PURPOSE We evaluated the various accompanied malformations in patients with anal atresia or tracheoesophageal fistula (TEF). Furthermore, we determined the prevalence of VACTERL association and compared the clinical findings with those of patients without VACTERL association. METHODS We enrolled the patients with anal atresia or TEF with/without esophageal atresia. We collected the patient data pertaining to accompanied vertebral, cardiovascular, renal or limb anomalies, single umbilical artery, maternal diabetes mellitus or drug history, and gene research. RESULTS A total 155 patients (65 boys and 90 girls) were enrolled with 147 cases of anal atresia, 3 cases of TEF, and 5 cases of anal atresia with TEF. The prevalence of accompanied anomalies was 67.1% in cardiovascular, 27.1% in renal, 9.7% in vertebral, 2.6% in limb anomalies, and 3.9% in single umbilical artery. Thirty-six (23.2%) patients were diagnosed with VACTERL association. The patients with VACTERL association had a significantly higher number of male patients (58.3 vs. 37.0%, p = .033) and single umbilical artery (11.1 vs. 1.7%, p = .026), and had a significantly lower birth weight (2.8 vs. 3.1 kg, p = .033) than the patients without VACTERL association. Genetic studies were performed in 111 patients, and 8 (7.2%) had chromosomal abnormalities-3 in VACTERL and 5 in no VACTERL group. CONCLUSION We recommend a careful evaluation for VACTERL association in patients with anal atresia or TEF. It is particularly important to screen for a single umbilical artery for features of VACTERL association as well as for other congenital anomalies.

Abstract
VACTERL association (OMIM 192350) is a heterogeneous clinical condition characterized by congenital structural defects that include at least 3 of the following features: vertebral abnormalities, anal atresia, heart defects, tracheoesophageal fistula, renal malformations, and limb defects. The nonrandom occurrence of these malformations and some familial cases suggest a possible association with genetic factors such as chromosomal alterations, gene mutations, and inherited syndromes such as Fanconi anemia (FA). In this study, the clinical phenotype and its relationship with the presence of chromosomal abnormalities and FA were evaluated in 18 patients with VACTERL association. For this, a G-banded karyotype, array-comparative genomic hybridization, and chromosomal fragility test for FA were performed. All patients (10 female and 8 male) showed a broad clinical spectrum: 13 (72.2%) had vertebral abnormalities, 8 (44.4%) had anal atresia, 14 (77.8%) had heart defects, 8 (44.4%) had esophageal atresia, 10 (55.6%) had renal abnormalities, and 10 (55.6%) had limb defects. Chromosomal abnormalities and FA were ruled out. In 2 cases, the finding of microalterations, namely del(15)(q11.2) and dup(17)(q12), explained the phenotype; in 8 cases, copy number variations were classified as variants of unknown significance and as not yet described in VACTERL. These variants comprise genes related to important cellular functions and embryonic development.

Abstract
Esophageal atresia/tracheoesophageal fistula (EA/TEF) is one of the most common gastrointestinal birth defects. It can occur in isolation or in association with other birth defects or genetic syndromes. We retrospectively reviewed the EA/TEF cases evaluated at Rady Children's Hospital San Diego (San Diego, CA) between 2007 and 2016. Data were collected for 157 patients. The majority of patients (105, 66.8%) had an associated major malformation present, and 52 patients (33.1%) had isolated EA/TEF. The patients with associated malformations were distributed as follows: 16 patients (10.2%) had a known genetic syndrome (the most common being Trisomy 21 in 11 patients); six patients (3.8%) had a suspected genetic syndrome; one patient had a suspected teratogenic syndrome (diabetic embryopathy); 30 patients had VACTERL association (19.1%); 32 patients had a "partial VACTERL" association (only two VACTERL-type defects without other malformation); nine patients (5.7%) had one additional non-VACTERL-type birth defect, two patients had VACTERL-type defects plus auricular malformations; and nine patients (5.7%) were classified as "unknown syndrome." A classification of the patterns of malformation of patients with congenital EA/TEF is proposed based on reviewing the data of this relatively large and phenotypically diverse patient group.

Spectrum of congenital anomalies among VACTERL cases: a EUROCAT population-based study. Pediatr Res 2020; 87:541-549.

Abstract
BACKGROUND The VACTERL (Vertebral anomalies, Anal atresia, Cardiac malformations, Tracheo-Esophageal fistula, Renal anomalies, Limb abnormalities) association is the non-random occurrence of at least three of these congenital anomalies: vertebral, anal, cardiac, tracheo-esophageal, renal, and limb anomalies. Diagnosing VACTERL patients is difficult, as many disorders have multiple features in common with VACTERL. The aims of this study were to clearly outline component features, describe the phenotypic spectrum among the largest group of VACTERL patients thus far reported, and to identify phenotypically similar subtypes. METHODS A case-only study was performed assessing data on 501 cases recorded with VACTERL in the JRC-EUROCAT (Joint Research Centre-European Surveillance of Congenital Anomalies) central database (birth years: 1980-2015). We differentiated between major and minor VACTERL features and anomalies outside the VACTERL spectrum to create a clear definition of VACTERL. RESULTS In total, 397 cases (79%) fulfilled our VACTERL diagnostic criteria. The most commonly observed major VACTERL features were anorectal malformations and esophageal atresia/tracheo-esophageal fistula (both occurring in 62% of VACTERL cases), followed by cardiac (57%), renal (51%), vertebral (33%), and limb anomalies (25%), in every possible combination. Three VACTERL subtypes were defined: STRICT-VACTERL, VACTERL-LIKE, and VACTERL-PLUS, based on severity and presence of additional congenital anomalies. CONCLUSION The clearly defined VACTERL component features and the VACTERL subtypes introduced will improve both clinical practice and etiologic research.

Abstract
High anorectal malformations (ARM) are associated with rectourinary fistulae. Augmented-pressure colostogram is the gold standard in diagnosing recto-urinary fistulae in cases of ARM. Cystoscopic assisted air colostogram can be used as an adjunctive diagnostic to augmented-pressure colostogram.
Introduction Anorectal malformations (ARM) in newborns classically present with the absence of a normal anus or an abnormally located anus. In a male infant with a high ARM, an initial diverting colostomy is later followed by a definitive posterior sagittal anorectoplasty (PSARP). Prior to definitive surgery an augmented-pressure colostogram is performed to identify the location of the fistula between the rectum and urogenital tract. However, on occasion, the augmented-pressure colostogram fails to identify the location of the fistula tract. We present a case of ARM where augmented-pressure colostogram failed to identify a fistula tract, thus requiring an alternative diagnostic approach. Presentation of case A newborn male presented with a high anorectal malformation and suspected rectourinary fistula on initial augmented-pressure colostogram. The patient ultimately underwent a laparoscopic assisted PSARP after cystoscopy with air colostogram identified the exact location of the fistulous connection in the prostatic urethra. Discussion Augmented-pressure colostogram remains the gold standard in diagnosing rectourinary fistulae in cases of ARM. However, a number of alternative and adjunctive techniques have been proposed in recent years. We provide a brief review of the literature in addition to a case presentation highlighting the potential benefits of pre-operative cystoscopy-assisted air colostogram in male patients with ARM. Conclusion Cystoscopy-assisted air colostogram via a distal mucous fistula can be utilized as an alternative diagnostic modality, especially when the augmented-pressure distal colostogram fails to identify rectourinary fistulae in high anorectal malformations.

Abstract
VACTERL/VATER association is a condition defined by the presence of at least three of the following congenital malformations: vertebral defects (V), anal atresia (A), cardiac defects (C), tracheo-oesophageal fistula (TE), renal anomalies (R) and limb abnormalities (L). We describe a stillborn female piglet with cardiac anomalies, renal defects, vertebral anomalies, anal atresia and a single umbilical artery (SUA), which are the main features of VACTERL association. In addition, the piglet had a unilateral abdominal wall defect. This was the only affected animal in a litter of 16 piglets. The molecular inductive mechanisms of this disorder are discussed, as well as the comparative and embryological implications.

Abstract
While mitotic errors commonly cause aneuploid clones soon after conception, the embryos often normalize as clones are rapidly eliminated. Although generally considered benign, evidence suggests clone elimination as the primary cause of the vertebral, ano-rectal, cardiac, tracheo-esophageal, renal, and limb (VACTERL) association of anomalies, and possibly other adverse outcomes as well. Here, clone elimination-related development disruption at specific locations is used as the basis of a comprehensive theoretical VACTERL association model that also elucidates mitotic mosaic aneuploidy effects. For the association, the model explains random temporal and spatial origins during a limited time frame and overlapping clusters of component anomalies. It supports early developmental effects involving the stage of determination, where the position in a specific morphogen field controls what a cell will become and where it will be located. Developmental properties related to determination also create specific vulnerabilities to the midline and distal defects, the latter explaining exclusively radial and tibial defects with duplications and deficiencies. The model also supports isolated anomalies as part of the association and, for mosaic mitotic aneuploidy, indicates that clone elimination nears completion at the time of lower limb determination. Although mosaic clone elimination may cause other defects, occurrences in different developmental fields separate them from VACTERL anomalies. Clone elimination may also be related to risks for a single umbilical artery and for non-structural adverse pregnancy outcomes such as losses, prematurity, and growth delays, while a paucity of clone lethality in non-humans explains the rarity of the association and of single umbilical arteries in animals.

Abstract
Congenital heart diseases are a common prenatal finding. The prenatal identification of an associated genetic syndrome or a major extracardiac anomaly helps to understand the etiopathogenic diagnosis. Besides, it also assesses the prognosis, management, and familial recurrence risk while strongly influences parental decision to choose termination of pregnancy or postnatal care. This review article describes the most common genetic diagnoses associated with a prenatal finding of a congenital heart disease and a suggested diagnostic process.

Abstract
In this single-center retrospective study, we analyzed kidney transplant outcomes in nine pediatric patients with VACTERL [vertebral defects, anal atresia, cardiac defects, tracheoesophageal fistula, renal anomalies, limb abnormalities] association-making this the largest study of its kind. Of 743 pediatric kidney transplant recipients at our center (1980-2017), nine had documented diagnoses of VACTERL association. All nine had congenital anorectal malformations and renal anomalies, five had vertebral defects, and one had a bifid thumb and tracheoesophageal fistula. Renal anomalies included dysplasia (n = 6), aplasia (n = 3), and horseshoe kidney (n = 2). Congenital lower urinary tract anomalies included neurogenic bladder (n = 6), obstructive uropathy (n = 4), anovesicular fistula (n = 1), rectourethral fistula (n = 1), and posterior urethral valves (n = 1). Age at transplant ranged from 1.2 to 15 years (mean, 7.3; standard deviation [SD], 5.5); 6 (67%) were male, and 3 (33%) were female; 6 (67%) had a living related donor, and 3 (33%) had a deceased donor. The overall graft survival rate was 78% (range, 1.5 to 25.2 years; mean, 10.5; SD, 8.9). One month post-transplant, one recipient died with a functioning graft. At 3.7 years post-transplant, one graft failed because of recurrent pyelonephritis. Post-transplant urologic complications included pyelonephritis (n = 6), vesicoureteral reflux (n = 5), and graft hydronephrosis (n = 4). We conclude that pediatric patients with VACTERL association can be safely transplanted-careful patient selection with vigilance and intervention for pre- and post-transplant urologic complications is essential.

Abstract
BACKGROUND VACTERL association is a sporadic, nonrandom series of congenital malformations diagnosed by the presence of three or more of the following: vertebral malformations, anal atresia, cardiac defects, tracheoesophageal fistula, renal malformations, and limb malformations. Situs inversus totalis (SIT) and esophageal malformations are rarely associated. This is the first reported case in North America of VACTERL association with SIT. IMPLICATIONS FOR PRACTICE Respiratory distress in the term infant requires full exploration of all possible causes because the etiology may be far more complex than routinely diagnosed respiratory distress syndrome. This particular case demonstrates physical exam findings and supportive imaging that would be observed in infants with VACTERL association and with SIT, highlighting considerations when, rarely, both occur simultaneously.

Impact of the associated anorectal malformation on the outcome of spinal dysraphism after untethering surgery. Pediatr Surg Int 2019; 35:227-231.

Abstract
PURPOSE To analyze the outcome after untethering surgery in patients with spinal dysraphism (SD), with or without associated anorectal malformation (ARM). METHODS Patients operated on for SD, with (Group A) or without (Group B) associated ARM (1999-2015), were included. The post-operative outcome was analyzed in the two groups in terms of improving of clinical symptoms (neuro-motor deficits, bladder dysfunction, bowel dysfunction) and of instrumental examinations (urodynamics, bladder ultrasound, neurophysiology). Fisher's exact test and χ2 test were used as appropriate; p < 0.05 was considered statistically significant. MAIN RESULTS Ten patients in Group A and 24 in Group B were consecutively treated. One patient was lost at follow up. Six patients (25%) in Group B underwent prophylactic surgery. The analysis of the pre-operative symptoms in the two groups showed that a significantly higher number of patients in group A needed bowel management and presented with neuro-motor deficits, compared to group B (p = 0.0035 and p = 0.04, respectively). Group A showed a significant post-operative neuro-motor improvement as compared to group B (p = 0.002). CONCLUSIONS Based on our results, untethering seems to be effective in neuro-motor symptoms in selected patients with ARM. In ARM patients, untethering surgery does not seem to benefit intestinal and urinary symptoms. The presence of the associated ARM does not seem to impact the medium-term outcome of patients operated for SD.

Abstract
The combination of vertebral, anal, cardiac, tracheo-esophageal, renal and limb anomalies termed VACTERL association, also referred to as VATER, has been used as a clinical descriptor and more recently, a diagnosis of exclusion, for a specific group of phenotypic manifestations that have been observed to co-occur non-randomly. Though the causes remain elusive and poorly understood in most patients, VACTERL association is thought to be due to defects in early embryogenesis and is likely genetically heterogeneous. We present data on 36 patients diagnosed with VACTERL association in addition to describing the phenotypic diversity of each component feature. Unique cases in our cohort include a patient with a 498.59 kb microdeletion in the 16p11.2 region and another with a 215 kb duplication in the 3p25.2 region. Our findings expand upon the current understanding of VACTERL association and guide future research aimed at determining its etiology.

Abstract
BACKGROUND This study evaluates screening practices and the incidence of associated anomalies in infants with anorectal malformations (ARM). METHODS We performed a multi-institutional retrospective cohort study of children born between 2007 and 2011 who underwent surgery for ARM at 10 children's hospitals. ARM type was classified based on the location of the distal rectum, and all screening studies were reviewed. RESULTS Among 506 patients, the most common ARM subtypes were perineal fistula (40.7%), no fistula (11.5%), and vestibular fistula (10.1%). At least 1 screening test was performed in 96.6% of patients, and 11.3% of patients underwent all. The proportion of patients with ≥1 abnormal finding on any screening test varied by type of ARM (p<0.001). Screening rates varied from 15.2% for limb anomalies to 89.7% for renal anomalies. The most commonly identified anomalies by screening category were: spinal: tethered cord (20.6%); vertebral: sacral dysplasia/hemisacrum (17.8%); cardiac: patent foramen ovale (58.0%); renal: hydronephrosis (22.7%); limb: absent radius (7.9%). CONCLUSION Screening practices and the incidence of associated anomalies varied by type of ARM. The rate of identifying at least one associated anomaly was high across all ARM subtypes. Screening for associated anomalies should be considered standard of care for all ARM patients. TYPE OF STUDY Multi-institutional retrospective cohort study. LEVEL OF EVIDENCE III.

Abstract
BACKGROUND Long gap oesophageal atresia occurs in approximately 10% of all oesophageal atresia infants and surgical repair is often difficult with significant postoperative complications. Our aim was to describe the perioperative course, morbidity, and early results following repair of long gap oesophageal atresia and to identify factors which may be associated with complications. METHODS This is a single center retrospective cohort study of consecutive patients with oesophageal atresia undergoing surgical repair at The Royal Children's Hospital Melbourne from January 2006 to June 2017. RESULTS Two hundred and thirty-nine consecutive oesophageal atresia infants included 44 long gap oesophageal atresia infants and 195 non-long gap infants. A high rate of prematurity (24.7%), major cardiac (17%), and other surgically relevant malformations (12.6%) was found in both groups. The median age at oesophageal anastomosis surgery was 65.5 days for the long gap group vs 1 day for the oesophageal atresia group (mean difference 56.8 days, 95% CI 48.1-65.5 days, P < .01). Surgery for long gap oesophageal atresia included immediate primary anastomosis (n = 10), delayed primary anastomosis (n = 11), oesophageal lengthening techniques (n = 12) and primary oesophageal replacement (n = 6). Long gap oesophageal atresia was not associated with an increased incidence of difficult intubation (OR 2.8, 95% CI 0.6-22.1, P = .17), intraoperative hypoxemia (OR 1.6, 95% CI 0.6-4.5, P = .32), or hypotension (OR 0.9, 95% CI 0.5-1.8, P = .81). The surgical duration (177.7 vs 202.1 minute, mean difference [95% CI], 28 [5.5-50.4 minutes], P = .04) and mean duration of postoperative mechanical ventilation (107 vs 199.8 hours, mean difference [95% CI], 91.8 [34.5-149.1 hours], P < .01) were shorter for the non-long gap group. Overall in-hospital mortality was 7.5% (15.9% long gap vs 5.6% non-long gap oesophageal atresia OR 1.1, 95% CI 0.4-3.4, P = .85). CONCLUSION Long gap oesophageal atresia infants have a similar incidence of perioperative complications to other infants with oesophageal atresia. Current surgical approaches to long gap repair, however, are associated with longer anesthetic exposures and require multiple procedures in infancy to achieve oesophageal continuity.

Abstract
ABSTRACT
A 2 mo old golden retriever presented with malformation of the left thoracic limb and a small circular indentation of the skin in the cranial thoracic spine. Radiographs showed a cleft between the second and fifth metacarpal bones of the left thoracic limb compatible with ectrodactyly and spina bifida affecting T4 and T5 vertebrae. Magnetic resonance imaging of the thoracic spine showed dorsal reposition of the spinal cord and a tract connecting from the dura mater to the skin. No other malformations were detected. Surgical excision of the tract was performed and histopathological examination diagnosed a dermoid sinus type IV. Dermoid sinus and spina bifida are well-recognized congenital spinal and spinal cord defects, yet association with other congenital malformation are rarely reported in dogs. The here-reported dog had spinal and spinal cord abnormalities with concurrent limb malformation, which are two components of a nonrandom association of birth defects described as VACTERL in people. To the authors' knowledge, this is the first report describing concurrent dermoid sinus type IV, spina bifida, and ectrodactyly in a dog, and highlights the importance of patient examination for occurrence of multiple malformations to provide an appropriate prognosis for an owner.

Abstract
BACKGROUND The vertebral defect, anal atresia, cardiac defect, tracheoesophageal fistula/esophageal atresia, renal defect, and limb defect association and Mayer-Rokitansky-Küster-Hauser syndrome are rare conditions. We aimed to present two cases with the vertebral defect, anal atresia, cardiac defect, tracheoesophageal fistula/esophageal atresia, renal defect, and limb defect association and Mayer-Rokitansky-Küster-Hauser co-occurrence from our local surgical center and through a systematic literature search detect published cases. Furthermore, we aimed to collect existing knowledge in the embryopathogenesis and genetics in order to discuss a possible link between the vertebral defect, anal atresia, cardiac defect, tracheoesophageal fistula/esophageal atresia, renal defect, and limb defect association and Mayer-Rokitansky-Küster-Hauser syndrome. CASE PRESENTATION Our first case was a white girl delivered by caesarean section at 37 weeks of gestation; our second case was a white girl born at a gestational age of 40 weeks. A co-occurrence of vertebral defect, anal atresia, cardiac defect, tracheoesophageal fistula/esophageal atresia, renal defect, and limb defect association and Mayer-Rokitansky-Küster-Hauser syndrome was diagnosed in both cases. We performed a systematic literature search in PubMed ((VACTERL) OR (VATER)) AND ((MRKH) OR (Mayer-Rokitansky-Küster-Hauser) OR (mullerian agenesis) OR (mullerian aplasia) OR (MURCS)) without limitations. A similar search was performed in Embase and the Cochrane library. We added two cases from our local center. All cases (n = 9) presented with anal atresia and renal defect. Vertebral defects were present in eight patients. Rectovestibular fistula was confirmed in seven patients. Along with the uterovaginal agenesis, fallopian tube aplasia appeared in five of nine cases and in two cases ovarian involvement also existed. CONCLUSIONS The co-occurrence of the vertebral defect, anal atresia, cardiac defect, tracheoesophageal fistula/esophageal atresia, renal defect, and limb defect association and Mayer-Rokitansky-Küster-Hauser syndrome is extremely rare. This group of patients has unusual phenotypic characteristics. The long-term outcome after treatment of defects is not well reported. A single unifying cause is not known and the etiology probably includes both genetic and non-genetic causes. We stress the importance of future studies to optimized treatment, follow-up, and etiology.

Abstract
We describe a neonate with VACTERL association and right-sided congenital diaphragmatic hernia (CDH). Such coexistence is rare. The lack of symptoms during the early neonatal period, the absence of bowel loops herniated into the right thoracic cavity, and an unfinished surgery led to clinical and radiological diagnostic difficulties. Respiratory distress occurred when the patient was 2 months old. Chest radiology plain film revealed typical findings of right-sided CDH. The diagnosis was confirmed after surgical exploration.

Abstract
PURPOSE The present study aims to identify clinical and pathological factors that can predict the risk of spinal cord anomalies (SCA) in patients with anorectal malformations (ARM), the need for neurosurgery, and to define the impact of SCA on the outcome of patients with ARM. METHODS A 16-year retrospective analysis of all patients treated at a single tertiary children's Hospital with diagnosis of ARM. Data were collected to assess the impact of defined clinical characteristics on prevalence of SCA (detected at MRI). Children surgically treated or not for SCA were compared for age, clinical symptoms and type of anomalies at surgery or at last follow-up, respectively. Moreover, patients with intermediate/high ARMs, with or without SCA were compared for neurogenic bladder (NB), constipation, soiling and need for bowel management (BM). RESULTS Two hundred and seventy-five children were treated for ARM in the study period, 142 had spinal MRI that showed SCA in 85. Patients with SCA had significantly higher prevalence of preterm birth (p < 0.05), cardiac anomalies (p = 0.02), vertebral anomalies (p = 0.0075), abnormal sacrum (p < 0.0001), and VACTERL association (p = 0.0233). Ten patients were surgically treated for SCA. The prevalence of neurological bladder and neuro-motor deficits, of vertebral and genital anomalies, particularly cryptorchidism, was significantly higher in the operated group (p < 0.01, for each analysis). In patients with intermediate/high ARMs, no significant difference was observed between those with or without SCA, in terms of prevalence of NB, intestinal function and need for BM. CONCLUSIONS In patients with ARM, factors that can predict a higher prevalence of SCA and also determine an increased indication to neurosurgery may be identified. SCA by itself does not seem to affect the functional prognosis of children with intermediate/high ARM. These data may help physicians in stratifying the clinical and diagnostic pathway of patients with ARM.

Abstract
VACTERL association is a condition comprising multisystem congenital malformations, causing severe physical disability in affected individuals. It is typically defined by the concurrence of at least three of the following component features: vertebral anomalies (V), anal atresia (A), cardiac malformations (C), tracheo-oesophageal fistula (TE), renal dysplasia (R) and limb abnormalities (L). Vertebral anomaly is one of the most important and common defects that has been reported in approximately 60–95% of all VACTERL patients. Recent breakthroughs have suggested that genetic factors play an important role in VACTERL association, especially in those with vertebral phenotypes. In this review, we summarised the genetic studies of the VACTERL association, especially focusing on the genetic aetiology of patients with vertebral anomalies. Furthermore, genetic reports of other syndromes with vertebral phenotypes overlapping with VACTERL association are also included. We aim to provide a further understanding of the genetic aetiology and a better evidence for genetic diagnosis of the association and vertebral anomalies.

Abstract
PURPOSE Anorectal malformations (ARM) can commonly occur in association with other congenital anomalies or as part of the combined anomaly. The present study aims to assess the outcome of patients with ARM and patients with ARM in VACTERL association. METHODS A 12-year retrospective analysis of all patients treated at a single tertiary children's institution with a diagnosis of ARM. We identified and compared patients with ARM to those with ARM in VACTERL association (3 or more anomalies). Data were collected for both groups to assess type of ARM, urinary incontinence (UI), constipation, soiling, dietary/laxative treatment, bowel management (BM) and surgical complications. Type of lesion and clinical outcomes were classified according to Krickenbeck International classification. Patients lost to follow-up, dead or not yet toilet-trained (or <4 years old) were excluded. RESULTS One hundred ninety-eight patients were identified, 174 enrolled in the study. Lesions were classified for each study group (VACTERL- vs VACTERL+) as perineal fistulas (36.4 vs 9.7%, p = 0.0028), rectourethral fistulas (prostatic and bulbar) (23.1 vs 38.7%, p = ns), rectovesical fistulas (3.5 vs 9.7%, p = ns), rectovestibular fistulas (19.6 vs 22.6%, p = ns), cloacal malformations (4.9 vs 9.7%, p = ns), no fistula (4.9 vs 3.2%, p=), others (7.7 vs 6.4%, p = ns). The frequency of both dietary/laxative treatment and BM, as well as surgical complications were significantly higher in patients with VACTERL. CONCLUSIONS The coexistence of VACTERL anomalies negatively affects not only the surgical outcome but also the bowel functioning. Therefore, a dedicated follow-up is strongly recommended. Further studies are needed to assess if this has an impact on the quality of life of these patients.

Abstract
PURPOSE The aim of this study was to compare the frequency and nature of VACTERL associations between children who underwent surgery for esophageal atresia/tracheoesophageal fistula (EA/TEF) and anorectal malformation (ARM). METHODS We identified all children who underwent surgery for EA/TEF and/or ARM at hospitals participating in the Pediatric Health Information System (PHIS) database between 2004 and 2012. PHIS is an administrative database of free-standing children's hospitals managed by the Child Health Corporation of America (Overland Park, KS) that contains patient-level care data from 43 hospitals. The complete records of patients in this cohort were cross-referenced for diagnoses of vertebral, cardiac, renal and limb anomalies. RESULTS 2689 children underwent repair of esophageal atresia. Mean gestational age was 36.5±3.2weeks and mean birth weight was 2536.0±758.7g. Associated VACTERL diagnoses included vertebral anomaly in 686 (25.5%), ARM in 312 (11.6%), congenital heart disease in 1588 (59.1%), renal disease in 587 (21.8%) and limb defect in 192 (7.1%). 899 (33.4%) had 3 or more anomalies and met criteria for a VACTERL diagnosis. 4962 children underwent repair of ARM. Mean gestational age was 37.4±2.7weeks and mean birth weight was 2895.2±765.1g. Associated VACTERL diagnoses included vertebral anomaly in 1562 (31.5%), congenital heart disease in 2007 (40.4%), EA/TEF in 348 (7.0%), renal disease in 1723 (34.7%) and limb defect in 359 (7.2%). 1795 (36.2%) had 3 or more anomalies and met criteria for a VACTERL diagnosis. CONCLUSION VACTERL associations are relatively common in children with EA/TEF and ARM and occur in specific clusters, with cardiac disease more common in EA/TEF and spinal and renal/urinary anomalies more common in ARM.

Abstract
The Hedgehog (Hh) signalling pathway plays many important roles in development, homeostasis and tumorigenesis. The critical function of Hh signalling in bone formation has been identified in the past two decades. Here, we review the evolutionarily conserved Hh signalling mechanisms with an emphasis on the functions of the Hh signalling pathway in bone development, homeostasis and diseases. In the early stages of embryonic limb development, Sonic Hedgehog (Shh) acts as a major morphogen in patterning the limb buds. Indian Hedgehog (Ihh) has an essential function in endochondral ossification and induces osteoblast differentiation in the perichondrium. Hh signalling is also involved intramembrane ossification. Interactions between Hh and Wnt signalling regulate cartilage development, endochondral bone formation and synovial joint formation. Hh also plays an important role in bone homeostasis, and reducing Hh signalling protects against age-related bone loss. Disruption of Hh signalling regulation leads to multiple bone diseases, such as progressive osseous heteroplasia. Therefore, understanding the signalling mechanisms and functions of Hh signalling in bone development, homeostasis and diseases will provide important insights into bone disease prevention, diagnoses and therapeutics.

Abstract
The vertebral, anal, cardiac, tracheoesophageal, renal, and limb birth defects (VACTERL) association is a rare, non-random constellation of congenital abnormalities among which urinary tract anomalies can be included. In the presence of these anomalies, patients are suspected to have a higher rate of renal failure than average. We report a case of a 22-year-old woman with VACTERL association and consequent end stage renal failure. A live-related kidney transplant was carried out successfully and the postoperative course was uncomplicated. The patient had immediate graft function. Risk factors that may complicate kidney transplant surgery in this patient population as well as considerations relevant to peritransplant management are discussed.

Abstract
High throughput assays tend to be expensive per subject. Often studies are limited not so much by the number of subjects available as by assay costs, making assay choice a critical issue. We have developed a framework for assay choice that maximises the number of true disease causing mechanisms ‘seen’, given limited resources. Although straightforward, some of the ramifications of our methodology run counter to received wisdom on study design. We illustrate our methodology with examples, and have built a website allowing calculation of quantities of interest to those designing rare disease studies.

Abstract
In this series the authors evaluate clinical, cytogenetic, environmental and inheritance characteristics of neonates with VACTERL association. Twenty-six patients were diagnosed with VACTERL association and had a normal somatometric profile. Fifty-eight percent cases were males. The frequency of each component was: vertebral defects (V), 77 %; anal atresia (A), 62 %; tracheo-esophageal fistula/esophageal atresia (TEF/EA), 58 %; renal anomalies (R), 58 %; limb abnormalities (L), 50 %, and cardiac malformations (C), 42 %. The most frequent combination was VAR (n = 3). Sixteen patients had non-VACTERL anomalies such as bilateral cryptorchidism (n = 4). Two probands (8 %) had first or second-degree relatives with two components. Five patients (19 %) had environmental factors that interacted with occurrence of VACTERL association. All patients had a normal karyotype. This study contributes to a better characterization of VACTERL phenotype in neonatal period. In spite of predominant sporadic occurrence, underlying genetic susceptibility and environmental influences point to a complex interplay between genes and environmental factors in VACTERL association.

Abstract
Scoliosis is a spinal deformity that can be seen in children of all ages. It is most commonly seen as an adolescent idiopathic condition. Progressive scoliosis between 25° and 45° before skeletal and physiologic maturity can be treated with a brace, whereas progressive scoliosis greater than 50° should be treated surgically. For children younger than 10 years, it is important to not only prevent scoliosis from worsening but to also maintain the growth of the spine and chest wall through the use of growth-friendly surgical techniques. Spinal fusion and instrumentation surgery is generally reserved for adolescent patients.

Abstract
BACKGROUND VACTERL association refers to a combination of congenital anomalies that can include: vertebral anomalies, anal atresia, cardiac malformations, tracheo-esophageal fistula with esophageal atresia, renal anomalies (typically structural renal anomalies), and limb anomalies. METHODS We conducted a description of a case series to characterize renal findings in a cohort of patients with VACTERL association. Out of the overall cohort, 48 patients (with at least three component features of VACTERL and who had abdominal ultrasound performed) met criteria for analysis. Four other patients were additionally analyzed separately, with the hypothesis that subtle renal system anomalies may occur in patients who would not otherwise meet criteria for VACTERL association. RESULTS Thirty-three (69%) of the 48 patients had a clinical manifestation affecting the renal system. The most common renal manifestation (RM) was vesicoureteral reflux (VUR) in addition to a structural defect (present in 27%), followed by unilateral renal agenesis (24%), and then dysplastic/multicystic kidneys or duplicated collected system (18% for each). Twenty-two (88%) of the 25 patients with a structural RM had an associated anorectal malformation. Individuals with either isolated lower anatomic anomalies, or both upper and lower anatomic anomalies were not statistically more likely to have a structural renal defect than those with isolated upper anatomic anomalies (p = 0.22, p = 0.284, respectively). CONCLUSION Given the high prevalence of isolated VUR in our cohort, we recommend a screening VCUG or other imaging modality be obtained to evaluate for VUR if initial renal ultrasound shows evidence of obstruction or renal scarring, as well as ongoing evaluation of renal health.

Abstract
BACKGROUND Congenital heart disease (CHD) is estimated to affect between 3 and 5% of all newborns. Extra-cardiac malformations are observed in 7 to 50% of patients with CHD. One relatively well-known association that can occur in the context of CHD is VACTERL. Controversy still remains regarding the definition of VATER association and its expansion to VACTERL, the appropriate diagnostic criteria and the overall incidence. METHODS We conducted a description of a case series to characterize the cardiac findings present in a cohort of patients meeting the criteria for VACTERL association. RESULTS Forty-six of 220 were eligible for inclusion into the study, 67% (31 of 46) had CHD. The most common CHD was ventricular septal defect, present in 18 of 31 patients (58%). There was no statistically significant association between CHD severity and the presence or absence of other VACTERL component features, specifically anorectal malformation (p = 0.18) or tracheo-esophageal fistula (p = 0.72). CHD presence also did not correlate with the presence of tracheo-esophageal fistula or anorectal malformation. CONCLUSION Although this study does not, by design, provide further evidence toward the questions of whether CHD is a defining feature of VACTERL association, the frequency of CHD in our cohort does lend support to it being an important medical consideration in patients with VACTERL association. Based on our experience, we strongly recommend a screening echocardiogram to evaluate for CHD in individuals with a potential diagnosis of VACTERL association.

Abstract
In order to identify genetic causes of VACTERL association (V vertebral defects, A anorectal malformations, C cardiac defects, T tracheoesofageal fistula, E esophageal atresia, R renal anomalies, L limb deformities), we have collected DNA samples from 20 patients diagnosed with VACTERL or with a VACTERL-like phenotype as well as samples from 19 aborted fetal cases with VACTERL. To investigate the importance of gene dose alterations in the genetic etiology of VACTERL association we have performed a systematic analysis of this cohort using a 180K array comparative genomic hybridization (array-CGH) platform. In addition, to further clarify the significance of PCSK5, HOXD13 and CHD7 genes in the VACTERL phenotype, mutation screening has been performed. We identified pathogenic gene dose imbalances in two fetal cases; a hemizygous deletion of the FANCB gene and a (9;18)(p24;q12) unbalanced translocation. In addition, one pathogenic mutation in CHD7 was detected, while no apparent disease-causing mutations were found in HOXD13 or PCSK5. Our study shows that although large gene dose alterations do not seem to be a common cause in VACTERL association, array-CGH is still important in clinical diagnostics to identify disease cause in individual cases.

Abstract
Background VATER association was first described in 1972 by Quan and Smith as an acronym which identifies a non-random co-occurrence of Vertebral anomalies, Anal atresia, Tracheoesophageal fistula and/or Esophageal atresia, Radial dysplasia. It is even possible to find out Cardiovascular, Renal and Limb anomalies and the acronym VACTERL was adopted, also, embodying Vascular, as single umbilical artery, and external genitalia anomalies. Methods Data on patients with esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) admitted in the Neonatal Intensive Care Unit (NICU) between January 2003 and January 2013 were evaluated for the contingent occurrence of typical VACTERL anomalies (VACTERL-type) and non tipical VACTERL anomalies (non-VACTERL-type). The inclusion criterion was the presence of EA with or without TEF plus two or more of the following additional malformations: vertebral defects, anal atresia, cardiovascular defects, renal anomalies and lower limb deformities, like radial dysplasia. Results Among 52 patients with EA/TEF, 20 (38,4%) had isolated EA and 7 (21,8%) had a recognized etiology such a syndrome and therefore were excluded. Among 32 infants with EA and associated malformations, 15 (46,8%) had VACTERL association. The most common anomalies were congenital heart defects (73,3%), followed by vertebral anomalies (66,6%). Many patients also had additional non-VACTERL-type defects. Single umbilical artery was the most common one followed by nervous system abnormalities and anomalies of toes. Between the groups of infants with VACTERL type and non-VACTERL-type anomalies, there are several overlapping data regarding both the tipically described spectrum and the most frequently reported non-VACTERL-type malformations. Thus, it is possible to differentiate infants with a full phenotype (VACTERL full phenotype) and patients that do not meet all the criteria mentioned above, but with some homologies with the first group (VACTERL partial phenotype). Conclusion The high frequency of non-VACTERL-type anomalies encountered in full and partial phenotype patients would suggest the need for an extension of the clinical criteria for the diagnosis of VACTERL association and also for pre- and post-operative management and follow-up in the short and long term.
