Abstract
INTRODUCTION AND IMPORTANCE Cloacal exstrophy (CE) is defined as a complex anomaly that affects the urogenital and intestinal tracts. It is the most serious form of anomaly that is described within the so-called exstrophy-epispadias complex. These malformations usually present a challenge in the management of particular conditions, as most of these forms require multiple surgeries, resulting in the use of multidisciplinary approaches, including reconstructive urologists, pediatric surgeons, orthopedic surgeons, endocrinologists, pediatricians, psychologists and nutritionists. Additionally, these patients present with ambiguous genitalia, which is another aspect that needs to be taken into consideration during the management of this condition. CASE PRESENTATION The first patient, a baby who was 8 days of life and referred from a peripheral hospital, presented with classic features of cloaca exstrophy. He underwent first-stage cloacal exstrophy repair. The intraoperative findings included a bi-halved bladder and phallus, and the ureters were not appreciated, but there was continuous urine leakage from the bi-halved bladder and no uterus or ovaries. Poorly formed cecum, cecal-cutaneous fistula with an everted part of the terminal ileum protruding outside (mucosa-out), no transverse, no descending colon, collapsing small bowel, left undescended testis in the inguinal region, and right abdominal undescended testis. He first underwent surgery, which involved ileostomy, omphalocele closure and proper bladder exstrophy construction. The second patient, a 6-day-old female, had a similar presentation and physical findings as the first patient did, except that she had elephantoid trunk deformity with a cecal fistula, bifid clitoris, two cervical orifices, and two uteri completely separated with ovaries. Mobilization of the hindgut, closure of the cecal fistula, and proper bladder exstrophy after repair of the posterior wall were performed. The third patient was a 10-day-old female, similar to the second patient, but this patient presented with a left leg deformity with wide diastasis. In this case, the urinary bladder was not bivalved, and the cecal fistula had perforated just below the posterior wall of the urinary bladder. A mild omphalocele, bifid clitoris and vagina, one cervical orifice, and two uteri completely separated, with ovaries observed. Mobilization of the hindgut, closure of the cecal fistula, and proper bladder exstrophy after repair of the posterior wall were performed. The postoperative period was uneventful. CLINICAL DISCUSSION Surgical management of cloacal exstrophy is typically undertaken in the newborn period (48-72 h) as a combined effort between pediatric surgery and urology. In the setting of associated spinal dysraphism, neurosurgical consultation and closure should be undertaken as soon as the infant becomes medically stable. Early operation minimizes bacterial colonization of exposed viscera and may decrease the need for pelvic osteotomy. The goals of treatment include securing the abdominal wall and bladder closure, preserving renal function, preventing short bowel syndrome, creating functional and cosmetically acceptable genitalia, and attaining acceptable urinary and fecal continence. CONCLUSION Cloacal exstrophy remains a rare and complex congenital anomaly characterized by an array of anatomical defects affecting multiple organ systems. With respect to the approach of this congenital malformation, it is therefore important that these individuals and their families remain under the care of a multidisciplinary team of providers who can offer medical care, counseling and life-long follow-up.

Abstract
Cloacal exstrophy is the most severe congenital anomaly of the exstrophy-epispadias complex and is characterized by gastrointestinal, genitourinary, neurospinal, and musculoskeletal malformations. Individualized surgical reconstruction by a multidisciplinary team is required for these complex patients. Not infrequently, patients need staged surgical procedures throughout childhood and adolescence. Following significant improvements in medical care and surgical reconstructive techniques, nearly all patients with cloacal exstrophy now survive, leading to an increased emphasis on quality of life. Increased attention is given to gender identity and the implications of reconstructive decisions. Long-term sequelae of cloacal exstrophy, including functional continence and sexual dysfunction, are recognized, and many patients require ongoing complex care into adulthood.

Abstract
Introduction The bladder exstrophy-epispadias complex is a rare congenital disease. Urothelial carcinomas rarely occur in patients with this disease, and there have been few reports on its treatment. Case presentation We report the case of a 44-year-old man with a hemorrhage from the external urethral meatus. He was diagnosed with bladder exstrophy-epispadias complex and underwent urinary diversion with substitution cystoplasty and Mitrofanoff appendicovesicostomy. Because computed tomography and magnetic resonance imaging suggested invasive bladder carcinoma in the defunctionalized bladder, we performed a cystectomy. The patient was diagnosed with urothelial carcinoma with glandular differentiation. One month after the surgery, nivolumab adjuvant chemotherapy was administered. The patient showed no signs of recurrence or metastasis after the treatment. Conclusion This is the first case of adjuvant nivolumab therapy for urothelial carcinoma with the bladder exstrophy-epispadias complex.

Zhan J, Jia F, Gao Q, Xiao X. A case report of single umbilical artery combined with fetal bladder exstrophy in singleton pregnancy and related literature review. BMC Pregnancy Childbirth 2024; 24:122. [PMID: 38336714 PMCID: PMC10854176 DOI: 10.1186/s12884-024-06318-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2023] [Accepted: 02/03/2024] [Indexed: 02/12/2024] Open
Abstract
BACKGROUND According to prenatal ultrasonographic studies, single umbilical artery may be present alone or in association with other fetal abnormalities. So far, the exact pathogenesis of bladder exstrophy is unclear. Some scholars believe that bladder exstrophy and cloacal exstrophy should be regarded as a disease spectrum to explore their pathogenesis. If bladder exstrophy and cloacal exstrophy are regarded as the same disease spectrum, then we can speculate that the single umbilical artery should have the probability of being accompanied by bladder exstrophy at the same time. CASE PRESENTATION For the first time, we report a rare case of fetal bladder exstrophy with single umbilical artery in single pregnancy. This patient underwent targeted color Doppler ultrasound at 26 weeks of pregnancy which first suspected bladder exstrophy with single umbilical artery and fetal MRI for diagnosis at 38 + 3 weeks of pregnancy which confirmed the suspicion. After the diagnosis was confirmed, the patient was scheduled for a multidisciplinary discussion. Ultimately the patient opted for induced fetal demise at 38 + 5 weeks of pregnancy and the physical appearance of the fetal demise affirmed previous ultrasound and MRI examination results. CONCLUSIONS Our report is the first finding of single umbilical artery combined with bladder exstrophy in a singleton pregnancy. Accordingly, our case enhances the evidence that cloacal exstrophy and bladder exstrophy should be treated as the same disease spectrum. In addition, we conducted a literature review on the diagnostic progress of single umbilical artery combined with bladder exstrophy, hoping to provide useful references for the diagnosis of this disease.

Abstract
BACKGROUND With improved operative techniques pregnancy rates have been rising in patients with anomalies of the extrophy-epispadias-complex, including also female patients with bladder extrophy. Specific risks around pregnancy need to be addressed sufficiently beforehand. CASE PRESENTATION An unplanned pregnancy was detected at 34 weeks in a 39-year old White female patient with former complex bladder extrophy. Decades after her operation she had not received any follow-up medical care and believed to be unable to conceive due to her anomaly. Thus no contraceptive matters were taken. The patient had lived in a stable relationship with regular sexual intercourse for many years. Until 34 weeks the pregnancy was uncomplicated, but then uterine prolapse and signs of beginning pre-eclampsia appeared, and a healthy girl was born with cesarean section. CONCLUSION As patients with bladder extrophy and other anomalies from the extrophy-epispadias-complex reach adolescence/adulthood, they need continuous medical follow-up and transition of care to adult surgery and gynecology in order to address specific aspects of sexual health, reproduction, contraception, and also cancer screening. In the presented case lack of transition of care resulted in an unplanned and complicated pregnancy.

Abstract
OBJECTIVE To examine the prenatal diagnosis rates of bladder exstrophy (BE) and Omphalocele-Exstrophy-Imperforate anus-Spinal Defect Syndrome (OEIS) in a large cohort of patients over a 20-year period. We hypothesized that prenatal diagnosis rates improved over time due to evolving techniques in fetal imaging. METHODS A multi-institutional database was queried to identify BE or OEIS patients who underwent primary closure between 2000 and 2020. We retrospectively determined prenatal or postnatal diagnosis. Those with unknown prenatal history were excluded. Multivariable logistic regression was used to investigate temporal pattern in rate of prenatal diagnosis while adjusting for sex and treating institution. RESULTS Among 197 BE and 52 OEIS patients, 155 BE and 45 OEIS patients had known prenatal history. Overall prenatal diagnosis rates of BE and OEIS were 47.1% (73/155) and 82.2% (37/45), respectively. Prenatal diagnosis rate was significantly lower in BE compared to OEIS (P <.0001). The prenatal diagnosis rate for BE significantly increased over time (OR 1.10; [95%CI: 1.03-1.17]; P = .003). Between 2000 and 2005, the prenatal diagnosis rate of BE was 30.3% (10/33). Between 2015 and 2020, prenatal diagnosis rate of BE was 61.1% (33/54). Prenatal diagnosis rate for OEIS did not change over time. Rates of prenatal diagnosis did not differ by sex or treating institution. CONCLUSION Rates of prenatal diagnosis of BE and OEIS are higher than previously reported. Prenatal diagnosis rate of BE doubled in the last 5 years compared to the first 5 years of the study period. Nonetheless, a significant proportion of both BE and OEIS patients remain undiagnosed prior to delivery.

Ebert AK, Zwink N, Reutter HM, Jenetzky E. A Prevalence Estimation of Exstrophy and Epispadias in Germany From Public Health Insurance Data. Front Pediatr 2021; 9:648414. [PMID: 34765573 PMCID: PMC8576352 DOI: 10.3389/fped.2021.648414] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Accepted: 09/21/2021] [Indexed: 11/13/2022] Open
Abstract
Introduction: The prevalence of rare diseases is very important for health care research. According to the European Surveillance of Congenital Anomalies (EUROCAT) registers, the live prevalence for exstrophy and/or epispadias (grades 1-3) is reported with 1:23,255 (95% CI: 1:26,316; 1:20,000). A Europe-wide prevalence evaluation based on reports from excellence centers estimates a prevalence for exstrophies of 1:32,200 and for isolated epispadias of 1:96,800 in 2010. However, the frequency of exstrophy [International Statistical Classification of Diseases and Related Health Problems revision 10 (ICD-10): Q64.1] and epispadias (ICD-10: Q64.0) treated in different age groups in Germany remains unclear. Material and Method: Public health insurance data from 71 million people (approximately 87% of the population) were provided by the German Institute for Medical Documentation and Information (DIMDI) in accordance to the German Social Insurance Code for this research purpose. DIMDI analyzed the data source for the ICD diagnoses exstrophy and epispadias between 2009 and 2011. As provided data were robust over the years, averaged data are mentioned. Detailed subgroup analysis of small numbers was forbidden due to privacy protection. Results: Annually, 126 persons of all ages with epispadias and 244 with exstrophy are treated as inpatients. In the observed population, 34 infants (<1 year of age) with epispadias and 19 with exstrophy (58% male) are treated as outpatients each year. This corresponds to an estimated live prevalence of 1:11,000 (95% CI: 1:14,700; 1:8,400) for EEC (exstrophy-epispadias complex), more specifically a prevalence of 1:17,142 for epispadias and of 1:30,675 for exstrophy. The male-to-female ratio for exstrophy is 1.4:1 for infants and 1.6:1 for all minors. In children and adolescents, 349 epispadias and 393 exstrophies (up to the age of 17) are treated annually, whereas adults with exstrophy and even more with epispadias make comparatively less use of medical care. Conclusion: With the help of DIMDI data, the live prevalence of bladder exstrophy and epispadias in Germany could be estimated. The prevalence of epispadias was higher than in previous reports, in which milder epispadias phenotypes (grade 1 or 2) may not have been included. These analyses might enlighten knowledge about nationwide incidence and treatment numbers of rare diseases such as the EEC.

Abstract
PURPOSE To represent the 15 years' experience of an academic referral center for the reconstruction of bladder exstrophy-epispadias complex with a modified single-stage approach. Single-staged reconstruction techniques are commonly used for classic bladder exstrophy. However, combined bladder closure and epispadias repair have been taken into great consideration in patients with initially failed reconstruction or delayed primary closure. METHODS A total of 49 boys underwent 1-stage bladder and epispadias repair with pubic bone adaptation and without the application of pelvic osteotomy. The mean ± SD age at surgery was 5.23 ± 2.04 months. Continence and social dryness were assessed in the follow-ups with 3 months intervals for the first year and biannually thereafter. RESULTS The mean ± SD of follow-up was 127.25 ± 71.32 months. Urethrocutaneous fistula, stricture, wound infection, and hemiglans were developed in six distinct patients. However, no other major complications were noted. Three patients (6.1%) remained incontinent; while 32 (65.3%) children were socially continent and 14 (28.6%) children were waiting for toilet training. All the patients without previous failed closure were socially continent, while all incontinent patients had two failed closures in their history. No patient was rendered hypospadiac. CONCLUSION Based on the experience of this institution, the application of single-stage reconstructive techniques can lead to continence, cosmetically pleasing appearance with promising outcomes, and reduction of overall operations, hospital stay and costs in the majority of cases as compared to multiple surgical procedures.

Abstract
Abstract
INTRODUCTION: Prenatal diagnosis of bladder exstrophy is extremley rare and difficult. BACKGROUND: Due to abnormal development of the cloacal membrane there is an incomplete closure of the lower abdominal wall, absence of the anterior wall of the bladder and external exposition of the posterior wall. The pubic bones are usually separated, the umbilical cord low inserted and there is abnormal external genitalia development. CASE REPORT: At 21st week of gestation of 39-year-old multigravida multipara referred by a primary care obstetrician to high-specialised centre for a detailed ultrasound examination with a suspicion of bladder absence and inferior umbilical localisation. At 29 weeks of gestation presence of bulging mass of 2 cm, between the umbilical outlet and labia was detected. At 31 weeks of gestation previously detected structure among thighs had 3 cm diameter with lateral umbilical outlet. Major labia were prominent and minor labia were within normal limits. Between two umbilical arteries with an appropriate intraabdominal course there were no transsonic area corresponding to the urinary bladder. The newborn baby was born at term in a good condition, but with an exposed bladder of 4 cm in diameter. The urethral outlet was not visualised and the female genitals were abnormal. After a month the girl underwent primary bladder exstrophy closure. Although she suffers from recurring urinary tract infections, she is in a good general condition. CONCLUSIONS: Due to prenatal diagnostics it was possible to detect and make an initial diagnosis of severe malformation. Early diagnosis allowed to prepare parents for a newborn with a defect and teach them how to take care of the baby.

Abstract
Cloacal exstrophy (CE) and persistent cloaca (PC) (alternatively termed urorectal septum malformation sequence [URSMS]), represent two major cloacal defects (CDs). Clinical characteristics and risk factors often are studied for both defects combined, rather than exploring if these defects have different etiologies. We enumerated clinical features for 47 CE and 54 PC (inclusive of URSMS) cases from the National Birth Defects Prevention Study. Thirty-three CE cases were classified as isolated and 14 as multiple (presence of unassociated major defects); respective totals for PC cases were 26 and 28. We compared selected child and maternal characteristics between 11,829 non-malformed controls and CE and PC cases using chi-square or Fisher's exact tests. Compared to controls, CE and PC cases were statistically more likely (p < 0.05) to be preterm; CE cases were more likely to be multiple births. We conducted logistic regression analysis to estimate odds ratios and 95% confidence intervals for any CD, CE, and PC with selected self-reported maternal prepregnancy and periconceptional (one month prior to 3 months following conception) exposures. In crude and adjusted analyses, we observed significant positive associations for any CD, CE, and PC with use of any fertility medication or assisted reproductive technology procedure. Significant positive associations observed only in crude analyses were any CD with maternal obesity or use of progesterone, any CD and CE with any x-ray, and any CD and PC with use of folate antagonist medications. Our findings provide some of the first insights into potential differing etiologies for CE and PC.

JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2017; 36:1801-1805.

Abstract
OBJECTIVES Bladder exstrophy is a rare severe congenital malformation. Early prenatal diagnosis is scarcely described in the literature. Low insertion of the umbilical cord is a constant anatomic feature of bladder exstrophy. The aim of our study was to assess whether early measurements of the umbilical cord insertion-to-genital tubercle length may serve as quantitative measurements for a low-inserted umbilical cord in cases of bladder exstrophy. METHODS The umbilical cord insertion-to-genital tubercle length was prospectively measured in all cases referred for a nonvisualized urinary bladder before 18 weeks' gestation. Final diagnoses were compared with prenatal measurements. RESULTS Fifteen fetuses were evaluated for a nonvisualized bladder at a mean gestational age of 15.7 weeks (range, 14-17 weeks). Of them, 6 cases were diagnosed with bladder exstrophy, and 9 cases had a normal urinary bladder. All cases with bladder exstrophy had an umbilical cord insertion-to-genital tubercle length below the fifth percentile for gestational age, whereas cases with a normal bladder had a normal measurement. CONCLUSIONS Fetuses with bladder exstrophy have an umbilical cord insertion-to-genital tubercle length below the fifth percentile of the general population. This measurement may serve as a complementary objective sonographic parameter in the prenatal assessment and counseling of cases suspected of having bladder exstrophy during early pregnancy.

Abstract
Highlights Associations between FA supplementation in pregnancy and effects on offspring's NTDs, allergy/respiratory problems, cancer and behaviour problems as been studied.There is growing concern about the effects of excessive FA supplementation, whether in terms of doses or times of exposure.FA supplementation in the periconceptional period is protective against NTDs while in later periods it could be deleterious.A daily dose of 0.4 mg FA in the periconceptional period seems to be effective and safe. Abstract Maternal folic acid (FA) supplementation is one of the most popular nutritional interventions during pregnancy for its protective effect against neural tube defects (NTDs).The purposes of this review are: (a) to gather the current evidence regarding supplementation of maternal diet with FA and (b) to problematize the available literature in terms of dosages, critical temporal windows, and its potential benefits and risks.The expression (pregnancy OR fetus OR offspring OR mother) AND ("folic acid" AND supplementation) was searched on PubMed database, filtering for articles published from 2005 to 2014. Publications referring to FA supplementation during the periconceptional period or pregnancy in which there was a conclusion about the effects of isolated FA supplementation on pregnant woman, pregnancy or offspring were included. Of the initial 1182 papers, 109 fulfilled the inclusion criteria.The majority of the publications reported FA supplementation outcomes on offspring's health, with emphasis in NTDs, allergy/respiratory problems, cancer and behaviour problems. Some inconsistency is observed on the impact of FA supplementation on different outcomes, except for NTDs. It is also visible an increased concern about the impact of excessive supplementation, either in terms of doses or exposure's duration.In conclusion, there is a growing interest in FA supplementation issues. The protective effect of FA supplementation over NTDs has been confirmed, being the periconceptional period a critical window, and it is frequently suggested that allergy/respiratory outcomes arise from (excessive) FA supplementation particularly later in pregnancy. Further research on critical doses and time of exposure should be conducted.

Qualitative questionnaire on the psychosocial wellbeing of mothers of children with BEEC. J Pediatr Urol 2017; 13:55.e1-55.e6.

Abstract
INTRODUCTION The bladder exstrophy-epispadias complex (BEEC) represents a spectrum of malformations that affect the anatomical and functional structure of the urogenital system. The parents of patients affected by this condition are subject to particularly stressful situations, such as worrying about their child's health, long hospital stays, concerns about the health and constant need for personal care for their children, that can profoundly compromise the quality of family life. OBJECTIVE The objective of this explorative qualitative study is to evaluate the social situation and the psychological strategies implemented by the mothers of children between 6 and 10 years of age who are affected by BEEC. STUDY DESIGN Fourteen mothers of children aged 6-10 years and affected by BEEC (9 boys and 5 girls) were interviewed. Data on the mothers' experiences were collected through semi-structured interviews (Table). RESULTS The qualitative analysis of the interviews showed that participants described experiences that were characterised by emotions such as fear and anger. Each mother had implemented a different and, sometimes, dysfunctional strategy in order to cope with the complex situation of the son/daughter. The aspects that most clearly emerged from mothers' descriptions were (1) the traumatic situation at the birth of the baby, (2) the sense of embarrassment concerning the pathological condition as the child was growing and the consequent sense of isolation of the mother, and (3) the fluctuation of feelings towards the multidisciplinary staff, which was sometimes seen as an important source of help and some other times as too destabilising and not helpful at all. DISCUSSION The study provided some insight into the psychological and social conditions experienced by mothers of children with BEEC, which could serve as a basis for developing multidisciplinary teams with greater awareness about families living with this condition and better timing in addressing their needs. CONCLUSIONS Mothers of children with BEEC show emotional and social difficulties. This is a crucial aspect to consider when planning a multidisciplinary approach to the treatment/therapy, especially considering that children examined in this study are approaching adolescence.

Abstract
INTRODUCTION Bladder exstrophy is a rare, congenital, complex malformation where the underlying cause is largely unknown. Both environmental and genetic mechanisms are thought to be involved. There are divergent results concerning the prevalence, birth descriptive data, and potential maternal risk factors for bladder exstrophy. Few previous studies have reflected nationwide populations, population registers, or spanned a longer period of time. OBJECTIVE To describe and assess bladder exstrophy and the potential maternal risk factors, for a time period of four decades, by conducting a nationwide register study of bladder exstrophy in Sweden. METHODS A matched-design, case-control, linkage-analysis study nested within the entire pool of live births in Sweden between 1973 and 2011 was performed. Cases with bladder exstrophy were identified using nationwide population-based birth and health registers. Inclusion criteria were people born in Sweden with the classification of bladder exstrophy according to the ICD coding system. Cases were matched with five controls per patient, based on birth year and sex. Prevalence was assessed and birth descriptive data were compiled. Potential maternal risk factors were obtained from medical birth registers of cases and assessed using conditional and multivariate logistic regression models to obtain odds ratios as a measure of the relative risk. Classification of the diagnosis in the registers constituted a possible limitation for determining the correct study population, which demanded strict validation and inclusion criteria. All data were collected prospectively, thereby avoiding potential recall bias. RESULTS The prevalence was calculated to be approximately 3 per 100,000 live births, with a male-to-female ratio of 1.14:1. In 92.5% of the cases, bladder exstrophy was an isolated malformation without associated major malformations. However, 41% had had surgery for congenital inguinal hernia and 11% of the male subjects had been operated on for cryptorchidism. A significantly higher proportion of cases had a birth weight <1500 g compared with controls, but other characteristics were comparable with controls. High maternal age was the only significant potential associated maternal risk factor. CONCLUSIONS One hundred and twenty children born with bladder exstrophy in Sweden during the last four decades were identified; this resulted in prevalence in Sweden of 3 per 100,000. The prevalence was stable over time and the sex ratio was equal. Birth characteristics were comparable to controls, and bladder exstrophy generally occurred as an isolated malformation without major associated malformations. Advanced maternal age was the only significant potential maternal risk factor.

Abstract
Background The bladder exstrophy-epispadias complex (BEEC) represents the severe end of the congenital uro-rectal malformation spectrum. Initial studies have implicated rare copy number variations (CNVs), including recurrent duplications of chromosomal region 22q11.21, in BEEC etiology. Methods To detect further CNVs, array analysis was performed in 169 BEEC patients. Prior to inclusion, 22q11.21 duplications were excluded using multiplex ligation-dependent probe amplification. Results Following the application of stringent filter criteria, seven rare CNVs were identified: n = 4, not present in 1307 in-house controls; n = 3, frequency of <0.002 in controls. These CNVs ranged from 1 to 6.08 Mb in size. To identify smaller CNVs, relaxed filter criteria used in the detection of previously reported BEEC associated chromosomal regions were applied. This resulted in the identification of six additional rare CNVs: n = 4, not present in 1307 in-house controls; n = 2, frequency <0.0008 in controls. These CNVs ranged from 0.03–0.08 Mb in size. For 10 of these 13 CNVs, confirmation and segregation analyses were performed (5 of maternal origin; 5 of paternal origin). Interestingly, one female with classic bladder extrophy carried a 1.18 Mb duplication of 22q11.1, a chromosomal region that is associated with cat eye syndrome. Conclusions A number of rare CNVs were identified in BEEC patients, and these represent candidates for further evaluation. Rare inherited CNVs may constitute modifiers of, or contributors to, multifactorial BEEC phenotypes.

Abstract
The Bladder-Exstrophy-Epispadias Complex (BEEC) represents the severe end of the uro-rectal malformation spectrum, and has a profound impact on continence, and on sexual and renal function. While previous reports of familial occurrence, in-creased recurrence among first-degree relatives, high concordance rates among monozygotic twins, and chromosomal aberra-tions were suggestive of causative genetic factors, the recent identification of copy number variations (CNVs), susceptibility regions and genes through the systematic application of array based analysis, candidate gene and genome-wide association studies (GWAS) provide strong evidence. These findings in human BEEC cohorts are underscored by the recent description of BEEC(-like) murine knock-out models. Here, we discuss the current knowledge of the potential molecular mechanisms, mediating abnormal uro-rectal development leading to the BEEC, demonstrating the importance of ISL1-pathway in human and mouse and propose SLC20A1 and CELSR3 as the first BEEC candidate genes, identified through systematic whole-exome sequencing (WES) in BEEC patients.

Abstract
Bladder exstrophy is a rare major birth defect which requires specialized surgical care. Associated genitourinary tract anomalies are extremely rare in this population, yet significantly impact surgical planning and outcomes. In this case, a full-term newborn girl with a prenatal diagnosis of classic bladder exstrophy was found to have a complete duplicated left collecting system with an ectopic ureter inserted to urethral plate. The patient underwent modern staged repair of exstrophy with bilateral anterior innominate osteotomies and concomitant ureteral reimplantation-the first reported case of ureteral reimplantation at the time of initial closure in a newborn.

Abstract
INTRODUCTION With advances in genitourinary reconstructive surgery, women with exstrophy-epispadias complex (EEC) have improved health and quality of life, and may reach reproductive age and consider pregnancy. Despite literature suggesting impaired fertility and higher risk with pregnancy, childbirth is possible. Medical comorbidities, including müllerian anomalies, contribute to increased risk of obstetric and urologic complications during pregnancy. OBJECTIVES We reviewed our experience with EEC patients who achieved pregnancy to investigate (1) urological characteristics of women who achieved pregnancy; (2) pregnancy management, complications, and delivery; and (3) neonatal outcomes. We developed recommendations for managing pregnancy in women with EEC. STUDY DESIGN/RESULTS This was a retrospective chart review of 36 female patients with EEC seen at our institution between 1996 and 2013. Female patients less than 18 years, and patients who did not have documented pregnancy were excluded. This resulted in a total of 12 patients with 22 pregnancies. All women with successful pregnancy had bladder exstrophy. The majority had undergone prior bladder augmentation (75%) and were on self-catheterization programs (92%). Thirty-six percent had symptomatic urinary tract infections (UTIs) during pregnancy. Five women had more than one pregnancy. There were four terminations of pregnancy. Of 18 desired pregnancies, there were four spontaneous abortions (SABs) (22%) and 16 live births (78%). The cesarean delivery (CD) rate was 100% (14/14), of which the majority were vertical (classical) uterine incisions with a paramedian skin incision. With the exception of one patient, there were no CD surgical complications. The mean gestational age at delivery was 36 weeks (Range 25 4/7 to 39 4/7 weeks) among eight pregnancies with known gestational age. There were no stillbirths, one neonatal death and no birth defects. DISCUSSION Women with EEC can have successful pregnancies, though at increased risk for preterm delivery and SABs. In our cohort, the rate of SAB is similar to that described in prior studies. Symptomatic UTIs likely due to self-catheterization were common. Cesarean delivery using a paramedian skin incision and classical uterine incision were not associated with major complications in this cohort. Limitations include reliance on retrospective data and small sample size. The strength of this study is the longitudinal detailed management of pregnancies in EEC women by a single team over time. A multidisciplinary approach to providing a continuum of care from pediatrics through adolescence to adulthood optimizes successful transitions, reproductive health, and successful pregnancies. Based on our experience, an algorithm providing guidance for pregnancy management was developed.

Abstract
This population-based descriptive epidemiology study demonstrates that rates of conjoined twins, teratomas, neural tube defects, microcephaly, and microphthalmia in the Rivne province of Ukraine are among the highest in Europe. The province is 200 km distant from the Chornobyl site and its northern half, a region known as Polissia, is significantly polluted by ionizing radiation. The rates of neural tube defects, microcephaly and microphthalmia in Polissia are statistically significantly higher than in the rest of the province. A survey of at-birth head size showed that values were statistically smaller in males and females born in one Polissia county than among neonates born in the capital city. These observations provide clues for confirmatory and cause-effect prospective investigations. The strength of this study stems from a reliance on international standards prevalent in Europe and a decade-long population-based surveillance of congenital malformations in two distinct large populations. The limitations of this study, as those of other descriptive epidemiology investigations, is that identified cause-effect associations require further assessment by specific prospective investigations designed to address specific teratogenic factors.

Abstract
Bladder exstrophy-epispadias complex (BEEC), the severe end of the urorectal malformation spectrum, has a profound impact on continence as well as sexual and renal functions. It is widely accepted that for the majority of cases the genetic basis appears to be multifactorial. Here, we report the first study which utilizes genome-wide association methods to analyze a cohort comprising patients presenting the most common BEEC form, classic bladder exstrophy (CBE), to identify common variation associated with risk for isolated CBE. We employed discovery and follow-up samples comprising 218 cases/865 controls and 78 trios in total, all of European descent. Our discovery sample identified a marker near SALL1, showing genome-wide significant association with CBE. However, analyses performed on follow-up samples did not add further support to these findings. We were also able to identify an association with CBE across our study samples (discovery: P = 8.88 × 10(-5); follow-up: P = 0.0025; combined: 1.09 × 10(-6)) in a highly conserved 32 kb intergenic region containing regulatory elements between WNT3 and WNT9B. Subsequent analyses in mice revealed expression for both genes in the genital region during stages relevant to the development of CBE in humans. Unfortunately, we were not able to replicate the suggestive signal for WNT3 and WNT9B in a sample that was enriched for non-CBE BEEC cases (P = 0.51). Our suggestive findings support the hypothesis that larger samples are warranted to identify association of common variation with CBE.

Abstract
INTRODUCTION Cloacal exstrophy is a rare condition characterized by a defect in the abdominal wall with extrusion of malformed abdominal contents. The normal separation of the genitourinary and gastrointestinal systems does not occur. While patients with cloacal exstrophy have a high incidence of spinal defects, cranial defects are rare. Chiari malformation has been rarely reported in children with cloacal exstrophy, although the embryogenesis is unknown. OBJECTIVE In this report, the authors describe a child with cloacal exstrophy and a large myelocystocele. The child also had an extensive Chiari II malformation. RESULTS We review the relevant embryology and suggest a possible mechanism for Chiari formation in this patient.

Abstract
The exstrophy-epispadias complex is a rare spectrum of malformations affecting the genitourinary system, anterior abdominal wall, and pelvis. Historically, surgical outcomes were poor in patients with classic bladder exstrophy and cloacal exstrophy, the two more severe presentations. However, modern techniques to repair epispadias, classic bladder exstrophy, and cloacal exstrophy have increased the success of achieving urinary continence, satisfactory cosmesis, and quality of life. Unfortunately, these procedures are not without their own complications. This review provides readers with an overview of the management of the exstrophy-epispadias complex and potential surgical complications.

Abstract
BACKGROUND/PURPOSE Bladder exstrophy-epispadias complex (BEEC) is thought to have a genetic component in its pathogenesis. Previously we found that p63(-/-) mice show increased ventral apoptosis and develop a BEEC phenotype. Down-regulation of the anti-apoptotic ΔNP63 and an up-regulation of pro-apoptotic TAP63 isoforms have been demonstrated in BEEC patient bladder tissues. We have previously shown that insertion/deletion polymorphisms of the ΔNp63 promoter are associated with an increased risk of BEEC. In this study, we specifically examined the TAP63 promoter to see if any sequence changes might lead to up-regulation of TAP63 and exaggerated apoptosis in BEEC patients. METHODS i) Bioinformatic analysis of the TAP63 promoter was performed to identify putative regulatory regions. ii) High-resolution Melt and Sanger sequencing was used to screen targeted regions in 112 BEEC patient DNA samples for potential sequence variants. iii) Sequence variation was analysed for significance against normal population frequency data. RESULTS i) We identified multiple epigenetic markers of transcriptional regulation within highly conserved areas of the TAP63 promoter sequence. ii) Of the 112 buccal swab DNA samples, adequate and successful screening ranged between 48 and 67 for each region. iii) No novel sequence variation or mutation was uncovered. iv) Two known SNPs were identified. However, allele frequency analysis was not statistically significant. CONCLUSION Our data do not associate genetic variation within the TAP63 promoter region with an increased risk of BEEC. Our data so far suggests that only ΔNP63 promoter aberration is involved in BEEC pathogenesis.

Abstract
The exstrophy-epispadias complex is a rare congenital malformation of the genitourinary system, abdominal wall muscles, and pelvic structures. Modern surgical repairs focus on reconstruction of the bladder and its adjacent structures, with the goal of achieving urinary continence, a satisfactory cosmetic result, and a high quality of life. Complex surgery in neonates and young children, as well as a prolonged postoperative course require close collaboration between surgeons, anesthesiologists, intensivists, pediatricians, and an experienced nursing staff. This article will review the spectrum of bladder exstrophy anomalies, the surgical repair, and the perioperative interdisciplinary management.

Abstract
PURPOSE Bladder exstrophy (BE) is an anterior midline defect that causes a series of genitourinary and muscular malformations, which demands surgical intervention for correction. Women with BE are fertile and able to have children without this disease. The purpose of this study is to assess the sexual function and quality of life of women treated for BE. MATERIALS AND METHODS All patients in our institution treated for BE from 1987 to 2007 were recruited to answer a questionnaire about their quality of life and pregnancies. RESULTS Fourteen women were submitted to surgical treatment for BE and had 22 pregnancies during the studied period. From those, 17 pregnancies (77.2%) resulted in healthy babies, while four patients (18.1%) had a spontaneous abortion due to genital prolapse, and there was one case (4.7%) of death due to a pneumopathy one week after delivery. There was also one case (5.8%) of premature birth without greater repercussions. During pregnancy, three patients (21.4%) had urinary tract infections and one patient (7.14%) presented urinary retention. After delivery, three patients (21.4%) presented temporary urinary incontinence; one patient (7.14%) had a vesicocutaneous fistula and seven patients (50%) had genital prolapsed. All patients confirmed to have achieved urinary continence, a regular sexual life and normal pregnancies. All patients got married and pregnant older than the general population. CONCLUSIONS BE is a severe condition that demands medical and family assistance. Nevertheless, it is possible for the bearers of this condition to have a satisfactory and productive lifestyle.

Abstract
OBJECTIVE To identify the pitfalls in accurate antenatal diagnosis of bladder exstrophy (BE) and cloacal exstrophy (CE), and thus understand the challenges for antenatal counselling. METHODS A prospectively maintained bladder exstrophy database of antenatal and live born referrals for BE/CE was used to identify patients. Data were collected about the antenatal scan findings and the outcome of pregnancy. RESULTS Between 2003 and 2009, 40 new babies with BE/CE were referred and of them 10 had an antenatal diagnosis. Five patients did not have a diagnosis despite suspicious findings noted on antenatal scans and another three had a wrong diagnosis of BE/CE. Of the 16 referrals with antenatal suspicion of BE/CE, 5 opted for termination. At the 20-week scan, it was possible to identify the gender of the fetus in 3/16 cases only. CONCLUSIONS Only a quarter of the babies born with BE/CE had received an antenatal diagnosis. Raising awareness about the condition amongst radiographers, and facilitating further scanning by a specialist fetal management unit if suspicious findings are noted, is crucial for improving the rate of detection. An antenatal diagnosis may not be reliable, and difficulty in identifying gender at the 20-week scan adds to the complexity of antenatal counselling. Magnetic resonance imaging and karyotyping may provide additional helpful information.

Abstract
OBJECTIVE To identify genetic and nongenetic risk factors that contribute to the severity of the bladder exstrophy-epispadias complex (BEEC). STUDY DESIGN Patients with BEEC from North America (n = 167) and Europe (n = 274) were included. The following data were collected: associated anomalies, parental age at conception, mode of conception, periconceptional folic acid supplementation, maternal risk factors during pregnancy, and environmental risk factors. The patients were divided into 3 subgroups according to phenotype severity: (i) mild, epispadias (n = 43); (ii) intermediate, classic bladder exstrophy (n = 366); and (iii) severe, cloacal exstrophy (n = 31). These subgroups then were compared with identify factors that contribute to phenotype severity. RESULTS Males were overrepresented in all subgroups. A relatively high prevalence of cleft lip, with or without cleft palate, was observed. Maternal smoking and medical radiation during the first trimester were associated with the severe cloacal exstrophy phenotype. Compliance with periconceptional folic acid supplementation was associated with the mildest phenotype (epispadias). CONCLUSIONS Periconceptional folic acid supplementation appears to prevent the development of the severe phenotype of BEEC.

Abstract
Cloacal exstrophy presents as a complex abdominal wall defect thought to result from a mesodermal abnormality. Anatomically, its main components are Omphalocele, bladder Exstrophy and Imperforate anus. Other associated malformations include renal malformations and Spine defects (OEIS complex). Historically, the prevalence ranges from 1 in 200,000 to 400,000 births, with higher rates in females. Cloacal exstrophy is likely etiologically heterogeneous as suggested by its recurrence in families and occurrence in monozygotic twins. The defect has been described in infants with limb-body wall, with trisomy 18, and in one pregnancy exposed to Dilantin and diazepam. Due to its rarity, the use of a nonspecific diagnostic code for case identification, and lack of validation of the clinical findings, cloacal exstrophy remains an epidemiologic challenge. The purpose of this study was to describe the prevalence, associated anomalies and maternal characteristics among infants born with cloacal exstrophy. We used data from the International Clearinghouse for Birth Defects Surveillance and Research submitted from 18 birth defect surveillance programs representing 24 countries. Cases were clinically evaluated locally and reviewed centrally by two authors. Cases of persistent cloaca were excluded. A total of 186 cases of cloacal exstrophy were identified. Overall prevalence was 1 in 131,579 births: ranging from 1 in 44,444 births in Wales to 1 in 269,464 births in South America. Live birth prevalence was 1 in 184,195 births. Prevalence ratios did not vary by maternal age. Forty-two (22.6%) cases met the criteria for the OEIS complex, whereas 60 (32.3%) were classified as OEI and 18 (9.7%) as EIS (one with suspected VATER (0.5%)). Other findings included two cases with trisomy 13 (one without a karyotype confirmation), one with mosaic trisomy 12 (0.5%), one with mosaic 45,X (0.5%) and one classified as having amnion band sequence (0.5%). Twenty-seven (14.5%) infants had other anomalies unrelated to cloacal exstrophy. Cloacal exstrophy is a rare anomaly with variability in prevalence by geographic location. The proportion of cases classified as OEIS complex was lower in this study than previously reported. Among all cases, 54.8% were reported to have an omphalocele.

Abstract
Bladder exstrophy (BE) is a complex congenital anomaly characterized by a defect in the closure of the lower abdominal wall and bladder. We aimed to provide an overview of the literature and conduct an epidemiologic study to describe the prevalence, and maternal and case characteristics of BE. We used data from 22 participating member programs of the International Clearinghouse for Birth Defects Surveillance and Research (ICBDSR). All cases were reviewed and classified as isolated, syndrome, and multiple congenital anomalies. We estimated the total prevalence of BE and calculated the frequency and odds ratios for various maternal and case characteristics. A total of 546 cases with BE were identified among 26,355,094 births. The total prevalence of BE was 2.07 per 100,000 births (95% CI: 1.90-2.25) and varied between 0.52 and 4.63 among surveillance programs participating in the study. BE was nearly twice as common among male as among female cases. The proportion of isolated cases was 71%. Prevalence appeared to increase with increasing categories of maternal age, particularly among isolated cases. The total prevalence of BE showed some variations by geographical region, which is most likely attributable to differences in registration of cases. The higher total prevalence among male cases and older mothers, especially among isolated cases, warrants further attention.

Cloacal exstrophy, one of the most severe congenital anomalies compatible with life, occurs in up to 1 in 200,000 lives births. The condition affects nearly every major organ system with severe neurologic, skeletal, gastrointestinal, and genitourinary ramifications. With increased understanding of the anatomy and embryology combined with refinements in prenatal diagnosis and postnatal care, there is now near-universal survival of patients with cloacal exstrophy. Functional and cosmetic outcomes have improved with modifications in surgical technique. However, debate continues regarding the issue of gender identity, and long-term data are still accruing with respect to the best strategy for management. Despite the extensive malformations noted, many patients have gone on to live fruitful lives.

Abstract
Classic bladder exstrophy (CBE) patients are born with a pubic diastasis that increases steadily with age from a mean value of 4 cm at birth to a mean of 8 cm at age 10, compared with a mean normal width of the pubic symphysis of 0.6 cm at all ages. The width of the sacrum and length of the posterior (iliac) segment of the pelvis in CBE patients are normal; however, the anterior (ischiopubic) segment of the pelvis is a mean 30% shorter and both the anterior and posterior segments are externally rotated compared to controls. The main role of osteotomy in treatment of CBE appears to be to relax tension on the bladder and repaired abdominal wall during wound-healing. Anterior innominate osteotomy with optional posterior vertical iliac osteotomy presents several advantages over the prior conventional technique of posterior iliac osteotomy. These include (a) less intraoperative blood loss, (b) better apposition and mobility of the pubic rami at the time of closure, (c) allowance for placement of an external fixator under direct vision, (d) allowance for secure external fixation in children over 6 months old, and (e) no requirement to turn the patient during the operation.

Abstract
STUDY OBJECTIVE To report our experience with surgical management of gynecological issues in postpubertal female patients born with classic bladder exstrophy (BE). DESIGN Retrospective review of clinical charts. SETTING Tertiary pediatric urology unit. PARTICIPANTS 16 postpubertal female BE patients. INTERVENTIONS Cosmetic surgery to the external genitalia, widening of vaginal introitus, and treatment of pelvic organ prolapse. MAIN OUTCOME MEASURES patient satisfaction and additional gynecological problems during follow-up. RESULTS Eight cases (14-43 years old) underwent cosmetic procedures. All resulted in improved cosmesis, but one case complained of reduced erogenous sensitivity after clitoridoplasty. Five cases (17-20 years old) underwent widening of the vaginal introitus. The modification was as short as possible to avoid any foreshortening of the dorsal vaginal wall. Three cases 33-45 years old presented with pelvic organ prolapse. All were sexually active. One had already given birth. All the three had previously been submitted elsewhere to a posterior vaginal cutback and one to hysterectomy. Two are still awaiting further treatment due to recurrent prolapse. CONCLUSION Female BE patients can seek advice to improve the appearance of the external genitalia at any ages. Clitoridoplasty should be considered carefully, because it may harm erogenous sensitivity. Problems with the vaginal introitus typically present at around 20 years of age, probably when BE patients become sexually active. Opening too widely the introitus can cause a foreshortening of the posterior vaginal wall, predisposing to pelvic organ prolapse. Treatment of pelvic organ prolapse is difficult.

Abstract
BACKGROUND The bladder exstrophy-epispadias complex (BEEC) is a spectrum of anomalies involving the abdominal wall, pelvis, urinary tract, genitalia, and, occasionally, the spine and anus. Although BEEC typically occurs sporadically, families with two or more affected members have been reported. The present authors previously conducted a genome-wide linkage analysis in two multiply affected (multiplex) families (one of German and one of Spanish origin), which revealed several chromosomal regions compatible with linkage. In the present study, genome-wide linkage analysis was performed in a recently reported consanguineous Iranian multiplex family with an affected sibling pair: a female with epispadias and a male with classic exstrophy of the bladder. METHODS The Affymetrix 250K Sty chip (238,304 single nucleotide polymorphisms) was used to genotype the parents and four children, including the two affected siblings. Parametric and nonparametric linkage analyses were performed. RESULTS Parametric linkage analysis under a recessive model with complete penetrance identified seven loci with LOD scores >1.6 (1p33, 4q31.21-22, 9q22.33, 12q13.13-2, 13q12.12-13, 18q23, and 19q13.31-41). These results were supported by nonparametric linkage analysis. Haplotype analysis showed that the affected individuals were homozygous identical by descent for all seven regions. Two of these regions overlapped with regions observed previously in the Spanish family -one on chromosome 4q31.21-22, and the other on chromosome 19q13.31-41. CONCLUSION These results suggest that chromosomal regions 4q31.21-22 and 19q13.31-41 are likely to harbor genes for an autosomal recessive form of BEEC.

Abstract
OBJECTIVE To provide a comprehensive overview of the clinical features, diagnosis, current management strategies, and outcomes of cloacal exstrophy. METHODS A PUBMED/Medline search of the literature was performed on cloacal exstrophy focusing on associated anomalies, treatment, and quality of life issues. RESULTS The incidence of cloacal exstrophy is between 1 in 200,000 and 400,000 live births. Survival rates now approach 100% secondary to improved understanding of underlying abnormalities and advances in neonatal care and surgical technique. Important principles of initial management include proper nutritional support, early closure of exstrophy, and preservation of intestinal length. The achievement of urinary and fecal continence remains a challenge. Data for long-term outcomes are now emerging which provide new insight into issues of gender identity, function, and psychosocial development of these patients. CONCLUSION Cloacal exstrophy remains a rare and complex congenital anomaly, characterized by an array of anatomical defects affecting multiple organ systems. A multidisciplinary approach to management is advocated with a focus on optimization of patient function and quality of life.

Abstract
Exstrophy-epispadias complex (EEC) represents a spectrum of genitourinary malformations ranging in severity from epispadias (E) to classical bladder exstrophy (CEB) and exstrophy of the cloaca (EC). Depending on severity, EEC may involve the urinary system, musculoskeletal system, pelvis, pelvic floor, abdominal wall, genitalia, and sometimes the spine and anus. Prevalence at birth for the whole spectrum is reported at 1/10,000, ranging from 1/30,000 for CEB to 1/200,000 for EC, with an overall greater proportion of affected males. EEC is characterized by a visible defect of the lower abdominal wall, either with an evaginated bladder plate (CEB), or with an open urethral plate in males or a cleft in females (E). In CE, two exstrophied hemibladders, as well as omphalocele, an imperforate anus and spinal defects, can be seen after birth. EEC results from mechanical disruption or enlargement of the cloacal membrane; the timing of the rupture determines the severity of the malformation. The underlying cause remains unknown: both genetic and environmental factors are likely to play a role in the etiology of EEC. Diagnosis at birth is made on the basis of the clinical presentation but EEC may be detected prenatally by ultrasound from repeated non-visualization of a normally filled fetal bladder. Counseling should be provided to parents but, due to a favorable outcome, termination of the pregnancy is no longer recommended. Management is primarily surgical, with the main aims of obtaining secure abdominal wall closure, achieving urinary continence with preservation of renal function, and, finally, adequate cosmetic and functional genital reconstruction. Several methods for bladder reconstruction with creation of an outlet resistance during the newborn period are favored worldwide. Removal of the bladder template with complete urinary diversion to a rectal reservoir can be an alternative. After reconstructive surgery of the bladder, continence rates of about 80% are expected during childhood. Additional surgery might be needed to optimize bladder storage and emptying function. In cases of final reconstruction failure, urinary diversion should be undertaken. In puberty, genital and reproductive function are important issues. Psychosocial and psychosexual outcome depend on long-term multidisciplinary care to facilitate an adequate quality of life.

Abstract
Introduction Bladder exstrophy is a rare urogenital abnormality. Other urogenital malformations have been associated with exposure to hormonal pesticide disruptors during critical developmental periods. This is the first report in the literature to associate household exposure to pesticides with bladder exstrophy. Case presentation We describe the pediatric environmental history of a newborn baby boy with isolated bladder exstrophy. In this case the pediatric environmental history includes the constitutional, genealogical, genetic and environmental factors related to bladder exstrophy, which revealed a cockroach infestation in the parents' home and the daily use of bug spray to kill them. The mother used one bottle of spray every 2 days (1000cc) and more in the summer, when the problem was worse. During gestational weeks 0-12, the mother intensively used a domestic pesticide consisting of a mixture of pyrethroids (cyfenothrin 0.5%, and tetramethrin 0.31%) and pyriproxyfen (0.01%). She described repeated episodes of mild to moderate poisoning that are associated with the use of household pesticides. The mother is a housewife and the father works as a fumigator of fruit fields and he reported gastrointestinal symptoms associated with the use of occupational pesticides. However, he did not believe he carried traces of these products into the home and his wife washed his work clothes separately. The pyrethroids and pyriproxyfen were detected in a urine sample obtained from the child 4 months after he was born. No other risk factors were identified. Conclusions A detailed and carefully conducted pediatric environmental history, which includes information about home pesticide use, should be carried out for all children with bladder exstrophy. Domestic exposure to pesticides during critical developmental periods may have deleterious effects for the fetus.
