Abstract
The extent of lung hypoplasia impacts the survival and severity of morbidities associated with congenital diaphragmatic hernia (CDH). The alveoli of CDH infants and in experimental models of CDH have thickened septa with fewer type II pneumocytes and capillaries. Fetal treatments of CDH-risk preterm birth. Therefore, treatments must aim to balance the need for increased gas exchange surface area with the restoration of pulmonary epithelial type II cells and the long-term respiratory and neurodevelopmental consequences of prematurity. Achievement of sufficient lung development in utero for successful postnatal transition requires adequate intra-thoracic space for lung growth, maintenance of sufficient volume and appropriate composition of fetal lung fluid, regular fetal breathing movements, appropriate gas exchange area, and ample surfactant production. The review aims to examine the rationale for current and future therapeutic strategies to improve postnatal outcomes of infants with CDH.

Abstract
BackgroundCongenital diaphragmatic hernia (CDH) is a cause of significant morbidity. CDH is the most common neonatal diagnosis requiring extracorporeal membrane oxygenation (ECMO).MethodsWe compared the different characteristics of ECMO and non-ECMO patients with CDH in a case-control study. Data were extracted from the Kids’ Inpatient Database. Records from 2006 to 2016 were used. Patients <28 days of age were selected. CDH infants (n=9217) were stratified based on whether they were treated with ECMO (n=348) or not (n=8869). Demographic data and hospital characteristics were collected. Categorical variables were analyzed using χ2 tests to determine associations between the ECMO-treated and non-ECMO-treated infants on demographic and clinical characteristics. Differences in hospitalization costs were analyzed using t-test. Multivariable logistic regression analyses were stratified by clinical and demographic characteristics to identify factors associated with ECMO. Significant variables were included in the model to determine predictors for ECMO.ResultsThe proportion of infants treated with ECMO was higher in White infants, and lower in Hispanics. The cost of hospitalization was higher with ECMO (p<0.0001). ECMO patients were more likely to be treated in their birth hospital (p<0.001), at an urban location (p<0.001) and more likely to have private insurance (p=0.011). After adjusting for confounders, odds of ECMO treatment remained lower in Hispanics (p=0.001) and self-payers (p=0.004).ConclusionThere was a decrease in the proportion of CDH infants needing ECMO use in the USA from 2006 to 2016. Disparities exist in ECMO use and mortality between different ethnic groups and regions of the USA.

Abstract
This review focuses on 2 fat-containing entities in the mediastinum that may raise a diagnostic challenge: Morgagni's hernia and Epipericardial (mediastinal) fat necrosis. Familiarity with the typical imaging findings of these 2 entities is vital for the radiologist to recognize and accurately characterize unusual mediastinal pathological conditions.

Abstract
To date, fetal liver implication is not a well-understood phenomenon in congenital diaphragmatic hernia (CDH). We evaluated the fetal morphologic changes on liver growth after surgical procedure in CDH experimental model. A diaphragmatic defect at gestational day E25 and tracheal occlusion (TO) at E27 were surgically created in rabbit fetuses. Five experimental groups were assessed: control group, left CDH, right CDH, CDH + TO, and TO alone. Body and organ growth were measured. For histological evaluation of the CDH effect, liver sections were collected. Left-CDH group had livers with increased leukocyte infiltration in comparison with controls (p = 0.02). Increased capillary sinusoid congestion and hepatocyte vacuolation were greater in left-CDH compared with the right-CDH group (p = 0.05). Capillary sinusoid congestion and interstitial edema were more evident in the left-CDH compared with CDH + TO group (p = 0.05). Increases in sinusoid congestion, hepatocyte vacuolation, and interstitial edema were also greater in the CDH + TO compared with controls (p ≤ 0.02). Intrathoracic liver weight was higher in right-CDH compared with left-CDH group (p < 0.001). Total lung weights (TLW) were significantly lower in both left-CDH compared with controls (p < 0.001), CDH + TO (p = 0.01), and TO (p < 0.01) and in right-CDH compared with CDH + TO (p < 0.01) and TO (p < 0.01). Decreased kidney and heart weights were also recorded. Hemodynamics and structural fetal liver changes in laterality were noted in CDH model. Regulation of intrathoracic liver weights seems to be disturbed by the absence of diaphragmic contact. Pulmonary injury is supported by the effect of a first hit, while the growth of internal organs suggests a multisystemic remodeling related to the fetal adaptation.

Front Pediatr 2022; 10:1020062. [PMID: 36389344 PMCID: PMC9659751 DOI: 10.3389/fped.2022.1020062] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2022] [Accepted: 10/07/2022] [Indexed: 11/23/2022] Open
Abstract
OBJECTIVE Congenital diaphragmatic hernia (CDH) is an uncommon but potentially life-threatening surgical condition in neonates. Surgery can be performed by either open or thoracoscopic techniques. In this study, we compared the clinical efficacy, safety, and effectiveness of thoracoscopic and open CDH repair. METHODS A retrospective review of neonates with CDH who underwent operations at our hospital from 2013 to 2021 was performed. The various perioperative parameters were compared between neonates undergoing thoracoscopic and open surgery. RESULTS There were 50 neonates in this study (37 in the thoracoscopic group and 13 in the open group). Thoracoscopic surgery was associated with significantly shorter hospital stay (13.32 vs. 18.77 days, p < 0.001); shorter duration of postoperative mechanical ventilation (3.70 vs. 5.98 days, p < 0.001); early feeding (4.34 vs. 7.46 days, p < 0.001); and shorter time to reach optimal feeding (8.21 vs. 13.38 days, p < 0.001). There was one postoperative death in the open group and no death in the thoracoscopic group. The median follow-up time of the two groups was 23.8 months (20.5 months in open group and 25.0 months in thoracoscopic group). Thoracoscopic surgery was associated with lower recurrence rates, but the difference was not statistically significant (2.7% vs. 7.7%, p = 0.456). CONCLUSION Thoracoscopy CDH repair, a safe and effective surgical technique for neonates, has better cosmesis, faster postoperative recovery, and a lower recurrence rate than other procedures. It can be considered the first choice for CDH treatment for neonates among experienced surgeons.
