Abstract
PURPOSE This study determined the prevalence, mortality, and time trends of children with congenital diaphragmatic hernia (CDH). METHODS Twenty-five hospital- and population-based surveillance programs in 19 International Clearinghouse for Birth Defects Surveillance and Research member countries provided birth defects mortality data between 1974 and 2015. CDH cases included live births, stillbirths, or elective termination of pregnancy for fetal anomalies. Prevalence, cumulative mortality rates, and 95% confidence intervals (CIs) were calculated using Poisson regression and a Kaplan-Meier product-limit method. Joinpoint regression analyses were conducted to assess time trends. RESULTS The prevalence of CDH was 2.6 per 10,000 total births (95% CI: 2.5-2.7), slightly increasing between 2001 and 2012 (average annual percent change = 0.5%; 95% CI:-0.6 to 1.6). The total percent mortality of CDH was 37.7%, with hospital-based registries having more deaths among live births than population-based registries (45.1% vs. 33.8%). Mortality rates decreased over time (average annual percent change = -2.4%; 95% CI: -3.8 to 1.1). Most deaths due to CDH occurred among 2- to 6-day-old infants for both registry types (36.3%, hospital-based; 12.1%, population-based). CONCLUSIONS The mortality of CDH has decreased over time. Mortality remains high during the first week and varied by registry type.

Abstract
Introduction: This study aimed to evaluate the cardiac function of fetuses with congenital diaphragmatic hernia by conventional echocardiography and spectral tissue Doppler imaging (s-TDI) and to evaluate the relationship between cardiac function and the severity of pulmonary hypoplasia. We also aimed to investigate the effect of diaphragmatic hernia side on fetal cardiac function.Methods: Fetal cardiac function were evaluated in 28 fetuses (20 with left-sided and 8 with right-sided) complicated with isolated congenital diaphragmatic hernia (CDH) and 56 gestational age matched control in this single center prospective study. s-TDI measurements were obtained at the right atrioventricular valve annulus. The annular peak velocities and their ratios, the time periods of cardiac cycle and myocardial performance index were calculated.Results: In comparison to controls, significantly prolonged isovolumetric contraction time (ICT') and isovolumetric relaxation time (IRT') and, significantly shortened ejection time (ET') were observed in fetuses with CDH by s-TDI. Fetuses with CDH also had higher myocardial performance index (MPI') z-scores compared to controls. There were no significant differences in terms of s-TDI cardiac function parameters between fetuses with right- and left-sided CDH. In correlation analysis, a significant positive correlation was found between ET' value and o/e LHR.Conclusion: The signs of both systolic and diastolic altered function were observed in fetuses with CDH with s-TDI independent of the side of the hernia, and a significant positive correlation was observed between fetal cardiac systolic function and the severity of pulmonary hypoplasia.

Abstract
PURPOSE Congenital diaphragmatic hernia (CDH) survivors experience increased risk of medical and neurodevelopmental challenges. This study describes the health-related quality of life (HRQOL), special education utilization and the family impact among neonatal CDH survivors. METHODS A single-center prospective cohort of CDH survivors born between 1995 and 2006 was followed. Parents completed the PedsQL HRQOL index and a Family Impact survey to assess the need for medical equipment, home health services, and special education and quantify the burden placed on the family by their child's medical needs. RESULTS Parents of 32 survivors participated at a mean survivor age of 8 ± 4 years. Many survivors utilized medical equipment (62%), home health services (18%) and special education (28%). CDH survivor HRQOL (79 ± 17) did not differ significantly from that of healthy children (83 ± 15, p = 0.12). HRQOL was diminished among survivors who required special education (67 ± 8 vs 82 ± 3; p = 0.04) and those reporting increased Family Impact score (p = 0.001). CONCLUSION Many CDH survivors continue to require home medical equipment and home health services at school age. Most survivors have normal parent-reported HRQOL; however, the need for special education and higher family impact of neonatal CDH correlates with decreased HRQOL.

Closer Look at the Nutritional Outcomes of Patients After Primary Repair of Congenital Diaphragmatic Hernia. J Pediatr Gastroenterol Nutr 2017; 65:237-241. [PMID: 28489671 DOI: 10.1097/mpg.0000000000001627] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/10/2022]
Abstract
OBJECTIVES We hypothesize that the patients after primary repair of congenital diaphragmatic hernia (CDH) can have poor nutritional outcomes and plan to identify risk factors to further stratify these patients. METHODS Retrospective cohort of patients who had primary repair of CDH between 2000 and 2014 and had follow-up at our institution. Z scores (weight for age and weight for length) were calculated using the World Health Organization and Centers for Disease Control and Prevention growth standards. RESULTS For the 67 patients in the cohort, the median age at the time of repair was 3 days (interquartile range 2-5) and at the time of discharge was 20.5 days (interquartile range 16-30). Fifteen percent of the patients required supplemental tube feeding for inadequate oral intake and 69% required fortified feedings for inadequate growth at discharge (4 patients subsequently needed gastrostomy tube placement). The median z scores at discharge were -1.0 (-2.1 to -0.3) and -1.2 (-2.3 to -0.5) in weight for age and weight for length, respectively. The risk factors for low z scores included open repair and longer periods of postoperative intubation or hospitalization. The z scores were similar at 6 months of age compared to discharge, but then statistically improved at 12 months of age. CONCLUSIONS Patients with primary repair of CDH are at risk for poor nutritional outcomes at the time of hospital discharge and require follow-up to ensure adequate growth. Patients at highest risk are those who had an open repair and had prolonged intubation or hospitalization.

Abstract
BACKGROUND With increasing survival of patients with more severe forms of congenital diaphragmatic hernia (CDH) and risk of long-term respiratory morbidity, studies on lung morphology are needed. We used hyperpolarised (3) He MRI and anatomical (1) H MRI in a cohort of young adult CDH patients to image regional lung ventilation and microstructure, focusing on morphological and micro-structural (alveolar) abnormalities. METHODS Nine patients with left-sided CDH, born 1975-1993, were studied. Regional ventilation was imaged with hyperpolarised (3) He MRI, and the (3) He apparent diffusion coefficient (ADC) was computed separately for the ipsilateral and contralateral lungs. (1) H MRI was used to image lung anatomy, total lung volume and motion during free-breathing. RESULTS (3) He MRI showed ventilation abnormalities in six patients, ranging from a single ipsilateral ventilation defect (3 patients) to multiple ventilation defects in both lungs (one patient treated with extra corporeal membrane oxygenation). In eight patients, (3) He ADC values for the ipsilateral lung were significantly higher than those for the contralateral lung. CONCLUSIONS Functional and micro-structural changes persist into adulthood in most CDH patients. Ipsilateral elevated (3) He ADC values are consistent with enlargement of mean dimensions of the confining lung micro-structure at the alveolar level.

Abstract
PURPOSE To determine developmental outcomes and associated factors in patients with congenital diaphragmatic hernia (CDH) at 2 years of age. METHODS This is a multicenter prospective study of a CDH birth cohort. Clinical and socioeconomic data were collected. Bayley Scales of Infant Development (BSID-III) and Vineland Adaptive Behavior Scales (VABS-II) were performed at 2 years of age. RESULTS BSID-III and VABS-II assessments were completed on 48 and 49 children, respectively. The BSID-III mean cognitive, language, and motor scores were significantly below the norm mean with average scores of 93 ± 15, 95 ± 16, and 95 ± 11. Ten percent (5/47) scored more than 2 standard deviations below the norm on one or more domains. VABS-II scores were similar to BSID-III scores with mean communication, daily living skills, social, motor, adaptive behavior scores of 97 ± 14, 94 ± 16, 93 ± 13, 97 ± 10, and 94 ± 14. For the BSID-III, supplemental oxygen at 28 days, a prenatal diagnosis, need for extracorporeal membrane oxygenation (ECMO) and exclusive tube feeds at time of discharge were associated with lower scores. At 2 years of age, history of hospital readmission and need for tube feeds were associated with lower scores. Lower socioeconomic status correlated with lower developmental scores when adjusted for significant health factors. CONCLUSION CDH patients on average have lower developmental scores at 2 years of age compared to the norm. A need for ECMO, oxygen at 28 days of life, ongoing health issues and lower socioeconomic status are factors associated with developmental delays.

Abstract
Congenital diaphragmatic hernia (CDH) is a congenital anomaly that presents with a broad spectrum of severity that is dependent upon components of pulmonary hypoplasia and pulmonary hypertension. While advances in neonatal care have improved the overall survival of CDH in experienced centers, mortality and morbidity remain high in a subset of CDH infants with severe CDH. Prenatal predictors have been refined for the past two decades and are the subject of another review in this issue. So far, all randomized trials comparing prenatal intervention to standard postnatal therapy have shown no benefit to prenatal intervention. Although recent non-randomized reports of success with fetoscopic endoluminal tracheal occlusion (FETO) and release are promising, prenatal therapy should not be widely adopted until a well-designed prospective randomized trial demonstrating efficacy is performed. The increased survival and subsequent morbidity of CDH survivors has resulted in the need to provide resources for the long-term follow up and support of the CDH population.

Does the ex utero intrapartum treatment to extracorporeal membrane oxygenation procedure change outcomes for high-risk patients with congenital diaphragmatic hernia? J Pediatr Surg 2012; 47:1053-7.

Abstract
PURPOSE In the most severe cases of congenital diaphragmatic hernia (CDH), significant barotrauma or death can occur before advanced therapies such as extracorporeal membrane oxygenation (ECMO) can be initiated. We have previously examined the use of the ex utero intrapartum treatment (EXIT) to ECMO procedure (EXIT with placement on ECMO) in high-risk infants and reported a survival advantage. We report our experience with EXIT to ECMO in a more recent cohort of our patients with most severe CDH. METHODS Every patient with less than 15% predicted lung volume during January 2005 to December 2010 was included. We obtained data on prenatal imaging, size and location of the defect, and survival. RESULTS Seventeen high-risk infants were identified. All 17 (100%) received ECMO and required a patch. Six children were delivered by EXIT to ECMO, and only 2 (33%) survived. An additional patient was delivered by EXIT to intubation with ECMO on standby and died. Of the 10 children who did not receive EXIT, 5 (50%) survived. CONCLUSIONS No clear survival benefit with the use of the EXIT to ECMO procedure was demonstrated in this updated report of our high-risk CDH population. The general application of EXIT to ECMO for CDH is not supported by our results.

Abstract
BACKGROUND/PURPOSE Although there has been a marked improvement in the survival of children with congenital diaphragmatic hernia (CDH) in the past 2 decades, there are few reports of long-term neurodevelopmental outcome in this population. The present study examined neurodevelopmental outcomes in 10- to 16-year-old CDH survivors not treated with extracorporeal membrane oxygenation (ECMO). METHODS Parents of 27 CDH survivors completed questionnaires assessing medical problems, daily living skills, educational outcomes, behavioral problems, and executive functioning. Fifteen CDH survivors and matched full-term controls completed standardized intelligence, academic achievement, phonological processing, and working memory tests. RESULTS Non-ECMO-treated CDH survivors demonstrated high rates of clinically significant difficulties on standardized academic achievement measures, and 14 of the 27 survivors had a formal diagnosis of specific learning disability, attention deficit hyperactivity disorder, or developmental disability. Specific problems with executive function, cognitive and attentional weaknesses, and social difficulties were more common in CDH patients than controls. Perioperative hypocapnia was linked to executive dysfunction, behavioral problems, lowered intelligence, and poor achievement in mathematics. CONCLUSIONS Non-ECMO-treated CDH survivors are at substantial risk for neurodevelopmental problems in late childhood and adolescence.

Abstract
PURPOSE Variable approaches to the care of infants with congenital diaphragmatic hernia (CDH) by multiple providers may contribute to inconsistent care. Our institution developed a comprehensive evidence-based protocol to standardize the management of CDH infants. This report reviews patient outcomes before and after the implementation of the protocol. METHODS Retrospective chart review of CDH infants managed with individualized care (preprotocol group, January 1997-December 2001, n = 22) or on the protocol (Protocol group, January 2002-July 2009, n = 47). Survival and other categorical variables were compared by chi(2) analysis, and continuous variables were compared using 1-sided analysis of variance analysis, with significance defined as P < .05. RESULTS Survival to discharge was significantly greater in the Protocol group (40/47; 85%) than the preprotocol group (12/22; 52%; P = .006), although mean gestational age, mean birth weight, and expected survival were not statistically different between the 2 groups. The use of supportive therapies, including high-frequency jet ventilation, inhaled nitric oxide, and extracorporeal life support, was similar between groups as well. CONCLUSIONS Since the implementation of a management protocol for infants with CDH, survival has improved significantly compared with expected survival and preprotocol controls. Reduction in the variability of care through use of an evidence-based protocol may improve the survival of CDH infants.

The most important prenatal predictor of outcome in left-sided CDH is liver position. More precise and reproducible prenatal predictive parameters need to be developed to allow standardization of results between centers and appropriate design of clinical trials in CDH. Thus far, all randomized trials comparing prenatal intervention to standard postnatal therapy have shown no benefit to prenatal intervention. Although recent non-randomized reports of success with balloon tracheal occlusion (and release) are promising, prenatal therapy should not be widely adopted until a well-designed prospective randomized trial demonstrating efficacy is performed. The increased survival and subsequent morbidity of CDH survivors has resulted in the need to provide resources for the long-term follow-up and support of the CDH population.

Abstract
OBJECTIVE Although survivors of congenital diaphragmatic hernia (CDH) are at high risk for brain injury, little is known about their neurodevelopment. Studies exploring short-term outcomes in children who received extracorporeal membrane oxygenation (ECMO) therapy suggest an increased risk for abnormalities in tone and/or motor development. This study provides the first detailed examination of visual and fine-motor outcomes in adolescent survivors of high-risk CDH (manifesting within the first 24 h) who did not receive ECMO. STUDY DESIGN A total of 13 CDH survivors (mean age 12.9 years) and 11 typically developing controls, matched to the CDH sample in terms of age at test, intelligence quotient and socioeconomic status (SES), completed a battery of visual and motor tests. RESULTS CDH survivors performed normally on motor-free tests of visual-perceptual function and on tests requiring visual discrimination and scanning, but were impaired on tests requiring visual-motor integration and oral-motor programming. CONCLUSION Survivors of high-risk CDH who did not receive ECMO treatment are at risk for long-term problems with oral motor and visuomotor control.

Impaired somatic growth and delayed lung development in infants with congenital diaphragmatic hernia--evidence from a 10-year, single center prospective follow-up study. J Pediatr Surg 2009; 44:1309-14. [PMID: 19573653 DOI: 10.1016/j.jpedsurg.2008.10.047] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2008] [Revised: 08/08/2008] [Accepted: 10/06/2008] [Indexed: 11/17/2022]
Abstract
PURPOSE In infants with congenital diaphragmatic hernia (CDH), somatic growth and pulmonary development are key issues beyond the time of intensive care treatment. The aim of the study was to investigate the somatic growth and pulmonary function after discharge and to compare CDH patients with a group of matched controls. METHODS Anthropometric measurements and lung function tests were performed in 26 infants after surgical repair of CDH and 26 non-CDH intensive care patients, matched for gestational age and birth weight. Spontaneously breathing infants were tested at a mean of 44 weeks postconceptional age (range, 36-58 weeks). Body weight, body length, respiratory rate (RR), tidal volume (V(T)), functional residual capacity by body plethysmography (FRC(pleth)), respiratory compliance (C(rs)), and respiratory resistance (R(rs)) were measured. RESULTS The mean (SD) weight gain per week in the CDH infants was significantly lower compared to non-CDH infants (89 [39] g vs 141 [49] g; P = .002). The breathing pattern between both groups differed considerably. In CDH infants, V(T) was significantly lower (P < .001) and RR significantly higher (P = .005). The respiratory compliance was also significantly (P < .001) reduced, whereas R(rs) did not differ significantly. No statistically significant differences were seen in FRC(pleth) related to the body weight between CDH and non-CDH infants (20.3 [4.4] mL/kg vs 21.5 [4.9] mL/kg). CONCLUSION Despite apparently well-inflated lungs after surgery, evidence of early and significantly reduced weight gain and impaired lung function in CHD patients should prompt careful dietary monitoring and regular lung function testing.

Abstract
PURPOSE The aim of this study is to determine if there has been a true, absolute, or apparent relative increase in congenital diaphragmatic hernia (CDH) survival for the last 2 decades. METHOD All neonatal Bochdalek CDH patients admitted to an Ontario pediatric surgical hospital during the period when significant improvements in CDH survival was reported (from January 1, 1992, to December 31, 1999) were analyzed. Patient characteristics were assessed for CDH population homogeneity and differences between institutional and vital statistics-based population survival outcomes. SAS 9.1 (SAS Institute, Cary, NC) was used for analysis. RESULT Of 198 cohorts, demographic parameters including birth weight, gestational age, Apgar scores, sex, and associated congenital anomalies did not change significantly. Preoperative survival was 149 (75.2%) of 198, whereas postoperative survival was 133 (89.3%) of 149, and overall institutional survival was 133 (67.2%) of 198. Comparison of institution and population-based mortality (n = 65 vs 96) during the period yielded 32% of CDH deaths unaccounted for by institutions. Yearly analysis of hidden mortality consistently showed a significantly lower mortality in institution-based reporting than population. CONCLUSION A hidden mortality exists for institutionally reported CDH survival rates. Careful interpretation of research findings and more comprehensive population-based tools are needed for reliable counseling and evaluation of current and future treatments.

Abstract
Pulmonary hypoplasia and persistent pulmonary hypertension are the most important reasons for the high morbidity and mortality of congenital diaphragmatic hernia (CDH). Despite surgical advances and advances in neonatal intensive care, the mortality still remains high. Then the research on how to improve prenatal fetal lung growth has become a focus. Some researches involved in fetal surgery, tracheal occlusion, prenatal use of corticosteroids etc., have been carried out in CDH animal models and humans. But the results either showed no benefit for the outcome of CDH or were unproved. Tetrandrine is a bisbenzylisoquinoline alkaloid isolated from the root of Stephania tetrandra. It has been used in traditional Chinese medicine for several decades to treat patients with silicosis, asthma and pulmonary hypertension etc. Some researches showed that prenatal tetrandrine administration can improve the lung development in CDH rat models. We hypothesize that prenatal treatment with tetrandrine can reverse the abnormal condition in the lung of newborn with CDH, and thus decrease the mortality.

Abstract
AIMS To compare surgical results for congenital diaphragmatic hernia (CDH) in two Scandinavian university hospitals and to evaluate the effects of abortions on the clinical profile of CDH in Iceland. METHODS A retrospective study including all CDH-cases in Iceland 1983-2002 and children referred to Lund University Hospital 1993-2002. Aborted fetuses with CDH from a nation-wide Icelandic abort-registry were also included. RESULTS In Iceland, 19 out of 23 children with CDH were diagnosed < 24 hours from delivery, one with associated anomalies. Eight fetuses were diagnosed prenatally and seven of them aborted, three having isolated CDH at autopsy. In Iceland, 15 of 18 children operated on survived surgery (83% operative survival). In Lund 28 children were treated with surgery, 23 of them diagnosed early after birth or prenatally. Four children did not survive surgery (86% operative survival) and 9 (31%) had associated anomalies. All the discharged children treated in Iceland and Lund are alive, 3-22 years postoperatively. CONCLUSION CDH is a serious anomaly where morbidity and mortality is directly related to other associated anomalies and pulmonary hypoplasia. However, majority of CDH patients do not have other associated anomalies. In spite of improved surgical results (operative mortality < 20%), a large proportion of pregnancies complicated with CDH are terminated. We conclude that the improved survival rate after corrective surgery must be emphasized when giving information to parents regarding abortion of fetuses with a prenatally diagnosed CDH.

Abstract
OBJECTIVE In congenital diaphragmatic hernia (CDH) the severity of pulmonary hypertension (PH) is considered, by several authors, determinant of clinical outcome. Plasmatic N-terminal-pro-B type natriuretic peptide (NT-proBNP) might be useful in diagnosis and management of PH in newborns, although its interest in CDH infants remains to be defined. Early NT-proBNP levels were assessed in CDH infants and correlated with cardiovascular echocardiographic parameters. PATIENTS AND METHODS 28 newborns, CDH and age-matched controls were enrolled in a prospective study. Clinical condition, NT-proBNP plasmatic levels, echo parameters of PH and biventricular function were assessed at 24 h after delivery as well as survival outcome. RESULTS Estimated mean pulmonary pressure and NT-proBNP were significantly higher in CDH than control infants. NT-proBNP significantly correlated with estimated pulmonary artery pressure, right ventricular Tei index, and tricuspid E/A ratio. Additionally, we found that CDH infants with NT-proBNP >11,500 pg/ml experienced a worse prognosis. CONCLUSIONS We demonstrated that PH is associated with NT-proBNP elevation and diastolic impairment in CDH infants. Early elevations in NT-proBNP levels seem to alert for a subset of CDH infants with worse prognosis.

Abstract
Impaired lung development afflicts a range of newborns cared for by paediatric surgeons. As a result the speciality has led in the development of surgical models that illustrate the biomechanical regulation of lung growth. Using transgenic mutants, biologists have similarly discovered much about the biochemical regulation of prenatal lung growth. Airway smooth muscle (ASM) and its prenatal contractility airway peristalsis (AP) represent a novel link between these areas: ASM progenitors produce an essential biochemical factor for lung morphogenesis, whilst calcium-driven biomechanical ASM activity appears to regulate the same. In this invited paper, I take the opportunity both to review our recent findings on lung growth and prenatal ASM, and also to discuss mechanisms by which ASM contractility can regulate growth. Finally, I will introduce some novel ideas for exploration: ASM contractility could help to schedule parturition (pulmonary parturition clock) and could even be a generic model for smooth muscle regulation of morphogenesis in similar organs.

Abstract
The purpose of this study was to demonstrate survival rate changes after the introduction of inhaled nitric oxide (iNO) therapy, and to identify the factors that influence these changes in neonates with a congenital diaphragmatic hernia (CDH) at a single center. A total of 48 neonates were divided into two groups based on the time of admission, i.e., into period I (P1; n=17; before the introduction of iNO therapy) and period II (P2; n=31; after the introduction of iNO therapy). Survival rates of the 48 neonates showed a tendency to increase from 53% during P1 to 77% during P2, but without a statistical significance, but a significant difference was found between survival rates during the two periods after adjusting for initial clinical characteristics, when the postoperative survival rate increased significantly from 69% for P1 to 100% for P2. The mean duration of preoperative respiratory management was significantly longer for P2 than for P1. Seven of 12 patients who received preoperative iNO therapy due to persistent pulmonary hypertension or refractory preductal hypoxemia in P2 survived after operation. We speculate that a management strategy based on iNO therapy and delayed operation, rather than differences between the initial clinical characteristics of the two study groups, might partially contribute to the observed improvements in postoperative and overall survival rates in neonates with CDH.

Abstract
BACKGROUND/PURPOSE The incidence of congenital diaphragmatic hernia (CDH) approximates 1 in 3000 births, with mortality rates up to 50%. The ability to accurately and easily predict the outcomes of these infants could be a valuable management tool. The purpose of this study was to develop and validate a simplified clinical method for predicting survival outcomes in infants born with CDH. METHODS The Wilford Hall/Santa Rosa clinical prediction formula (WHSR(PF) = highest PaO2 - highest PCO2) was generated from arterial blood gas values obtained during the initial 24 hours of life, but before surgical repair or extracorporeal membrane oxygenation, in a local group of infants with CDH identified by prospective and retrospective review. The WHSR(PF) was validated using a comparative group from the Congenital Diaphragmatic Hernia Study Group (CHDSG). Bivariate, multivariable, and area under the receiver operating curve (AUC) analysis was performed using SigmaStat and SPSS statistical programs (SPSS, Chicago, Ill). RESULTS As initially developed from the local data, the WHSR(PF) had a positive predictive value (PPV) of 82%, a negative predictive value of 88% and AUC of 0.87. When validated against the CDHSG data, the positive predictive value was 83%, negative predictive value was 66%, and AUC 0.79. Area under the receiver operating curve analysis by the previously published CDHSG predictive equation was 0.76. CONCLUSION This novel formula is an easy to apply clinical tool with similar or better predictive abilities compared to previous methods of predicting survival in infants born with CDH. Currently, no method appears to have sufficient clinical accuracy for predicting the outcome of an individual infant with CDH. Further studies are indicated.

Abstract
OBJECTIVE Review of cases of perinatally diagnosed congenital diaphragmatic hernias with special regard to time of diagnosis, organs herniated into the thorax, associated malformations, and outcomes. METHODS We analyzed the data of 106 cases between July 1, 1990, and June 30, 2005. The observation period was analyzed in two parts. RESULTS Prenatal ultrasound was performed in 89.6% (95/106) of the cases. 51.7% (46/89) of the pre- and postnatally verified congenital diaphragmatic hernia cases were diagnosed before the 24th week of gestation. 11% (11/100) of the hernias were identified postnatally. 71% (71/100) of the cases were associated with other malformations. The hernia was on the left side in 86% (86/100) and bilateral in 5% (5/100) of the cases. Between 1990 and 1997, the proportion of right-sided hernias was 4.3% (2/46), while during the second period it was 13% (7/54). 27.5% (14/51) of the newborns survived the perinatal period. The survival rate of the newborns delivered by caesarean section was three times higher than that of infants delivered vaginally. In the latter group, the rate of premature deliveries was considerably higher. The pregnancy was terminated in 45% (40/89) of the cases. 15% (6/40) of the terminated cases were isolated. Intrauterine or intrapartum deaths occurred in 5.6% (5/89) of the prenatally diagnosed cases. Simultaneous thoracic herniation of liver, spleen, or stomach decreased the survival rate. In these cases, the discharge rate was between 6 and 22%. CONCLUSIONS According to the analysis of 15-year data, the herniated organs, multiple malformations, as well as the mode of delivery influence the survival in a large number of cases. Early diagnosis predicts a large hernia, a higher malformation rate, and a less favourable prognosis.

Abstract
Congenital diaphragmatic hernia (CDH) affects 1 in every 2,000 to 4,000 live births. Many infants with this condition are diagnosed antenatally through routine ultrasound screening. Nearly 90 percent present at delivery with severe respiratory distress requiring intubation. Many of these infants develop persistent pulmonary hypertension of the newborn due to hypoplasia of the affected lung. The survival of infants with CDH is limited by the degree of pulmonary hypoplasia and requires sophisticated medical technology such as high-frequency ventilation and inhaled nitric oxide. Some infants also require treatment with extracoporeal membrane oxygenation. This article gives details of two cases of CDH in which the presentation was atypical. The more subtle presentation is discussed, as well as the embryology and pathophysiology of CDH and the possibility of associated anomalies. Clinical management and impact on the family are outlined.

Abstract
Congenital diaphragmatic hernia (CDH) retains high mortality due to lung hypoplasia and pulmonary hypertension. Efforts to improve survival and outcome have included fetal intervention, delivery at specialist centres, elective operation after stabilisation of labile physiology and minimising barotrauma. Permissive hypercapnea ('gentle ventilation') represents a significant advance in therapy gaining wider acceptance in centres worldwide. Human genetic studies are underway to identify candidate genes for the birth defect. Progress in the basic sciences may uncover critical aspects of developmental biology fundamental to CDH. Clinical trends in perinatal management of CDH are highlighted, which underpin the challenges of this lethal human anomaly.

Abstract
This is a review of cases of perinatally diagnosed congenital diaphragmatic hernia (CDH) with associated malformations with regard to time of diagnosis, side of hernia, associated malformations, and outcome. The authors analyzed the data of CDH cases with associated malformations from records of the I. Department of Obstetrics and Gynecology, Semmelweis University Faculty of Medicine, Budapest, between July 1, 1990 and June 30, 2005. The observed period was analyzed in two parts. The pre- and postnatal examinations verified CDH in 100 cases, 71% of which were associated with other malformations. In 52% (37/71) CDH was diagnosed before the 24th week of gestation. The rate of early diagnosed cases doubled in the second period. Ten percent (7/71) of cases were verified postnatally. Between 1990 and 1997, the percentage of right-sided hernia was 6% (2/34) while in the second period it was 19% (7/37). The association with cardiovascular, chest, and craniofacial anomalies doubled in the second period, while association of central nervous system anomalies halved. Chromosome anomalies were verified in four cases. Pregnancy was terminated in 53% (34/64) and 13% (4/30) of newborn infants survived the perinatal period. Intrauterine or intrapartum death occurred in 8% (5/64) of cases. The prevalence of cardiovascular, pulmonary, and craniofacial anomalies doubled, while that of central nervous system malformations decreased. The prevalence of other associated malformations has not changed significantly between the two periods. The improvement of technical facilities and accumulated experience make it possible to identify a higher number of associated malformations before the 24th week of gestation.

Abstract
Abstract Endoscopic laser ablation of placental vessels is the most commonly performed fetal operation today. Herein, we review the pathophysiology of twin-to-twin transfusion syndrome and the challenges of its treatment. Pediatric surgeons, with their knowledge of fetal and congenital pathology, and their technical expertise with minimally invasive surgery, can be of great benefit to the patient and the medical team.
