RESUMEN
Using a structured approach and expert consensus, we developed an evidence-based guideline on the treatment and prevention of non-specific back pain in children and adolescents. A comprehensive and systematic literature search identified relevant guidelines and studies. Based on the findings of this literature search, recommendations on treatment and prevention were formulated and voted on by experts in a structured consensus-building process. Physical therapy (particularly physical activity) and psychotherapy (particularly cognitive behavioral therapy) are recommended for treating pediatric non-specific back pain. Intensive interdisciplinary treatment programs should be provided for chronic and severe pain. Drug therapy should not be applied in children and adolescents. Further research on non-specific back pain in childhood and adolescence is strongly needed to reduce the imbalance between the high burden of non-specific back pain in childhood and adolescence and the low research activity in this field.
RESUMEN
Using a structured approach and expert consensus, we developed an evidence-based guideline on the diagnosis of back pain and the treatment of non-specific back pain in children and adolescents. The first part comprises etiology, risk factors, and diagnosis. The second part, published in the same issue, includes treatment and prevention. A comprehensive and systematic literature search was conducted to identify relevant guidelines and studies. Based on the findings of this literature search, recommendations on risk factors and diagnosis were formulated and voted on by experts in a structured consensus-building process. Notable red flags for specific back pain and evidence-based risk factors for non-specific back pain in children and adolescents were identified. Only three evidence-based recommendations could be formulated for causes, red flags, and risk factors for back pain, while two recommendations are based on expert consensus. Regarding diagnostics, eight expert consensus recommendations and one evidence-based recommendation could be provided. Despite the importance of adequate diagnosis for the treatment of back pain in children and adolescents, results of this work confirm the deficit in research investment in this area.
RESUMEN
Esophageal atresia with or without tracheoesophageal fistula (EA/TEF) is the most common congenital malformation of the upper digestive tract. This study represents the first genome-wide association study (GWAS) to identify risk loci for EA/TEF. We used a European case-control sample comprising 764 EA/TEF patients and 5,778 controls and observed genome-wide significant associations at three loci. On chromosome 10q21 within the gene CTNNA3 (p = 2.11 × 10-8; odds ratio [OR] = 3.94; 95% confidence interval [CI], 3.10-5.00), on chromosome 16q24 next to the FOX gene cluster (p = 2.25 × 10-10; OR = 1.47; 95% CI, 1.38-1.55) and on chromosome 17q12 next to the gene HNF1B (p = 3.35 × 10-16; OR = 1.75; 95% CI, 1.64-1.87). We next carried out an esophageal/tracheal transcriptome profiling in rat embryos at four selected embryonic time points. Based on these data and on already published data, the implicated genes at all three GWAS loci are promising candidates for EA/TEF development. We also analyzed the genetic EA/TEF architecture beyond the single marker level, which revealed an estimated single-nucleotide polymorphism (SNP)-based heritability of around 37% ± 14% standard deviation. In addition, we examined the polygenicity of EA/TEF and found that EA/TEF is less polygenic than other complex genetic diseases. In conclusion, the results of our study contribute to a better understanding on the underlying genetic architecture of ET/TEF with the identification of three risk loci and candidate genes.
RESUMEN
Esophageal atresia (EA) is a congenital anomaly that entails an interrupted esophagus with or without tracheoesophageal fistula (TEF). Depending on the distance of the two esophageal pouches a "short-gap" is distinguished from a "long-gap" variant. Up to 50% of newborns have additional anomalies. EA is prenatally diagnosed in 32-63% of cases. Recently, the interdisciplinary care in these children underwent substantial changes. Therefore, we summarize the current guideline of the German society of pediatric surgery for the treatment of patients with EA and distal TEF (Gross Type C). Controversies regarding the perioperative management include surgical-technical aspects, such as the thoracoscopic approach to EA, as well as general anesthesia (preoperative tracheobronchoscopy, intraoperative hypercapnia and acidosis). Moreover, postoperative complications and their management like anastomotic stricture are outlined. Despite significant improvements in the treatment of EA, there is still a relevant amount of long-term morbidity after surgical correction. This includes dysmotility of the esophagus, gastroesophageal reflux disease, recurrent respiratory infections, tracheomalacia, failure to thrive, and orthopedic complications following thoracotomy in the neonatal age. Therefore, close follow-up is mandatory to attain optimal quality of life.

INTRODUCTION: Esophageal atresia with or without tracheoesophageal fistula (EA/TEF) occurs approximately 1 in 3.500 live births representing the most common malformation of the upper digestive tract. Only half a century ago, EA/TEF was fatal among affected newborns suggesting that the steady birth prevalence might in parts be due to mutational de novo events in genes involved in foregut development. METHODS: To identify mutational de novo events in EA/TEF patients, we surveyed the exome of 30 case-parent trios. Identified and confirmed de novo variants were prioritized using in silico prediction tools. To investigate the embryonic role of genes harboring prioritized de novo variants we performed targeted analysis of mouse transcriptome data of esophageal tissue obtained at the embryonic day (E) E8.5, E12.5, and postnatal. RESULTS: In total we prioritized 14 novel de novo variants in 14 different genes (APOL2, EEF1D, CHD7, FANCB, GGT6, KIAA0556, NFX1, NPR2, PIGC, SLC5A2, TANC2, TRPS1, UBA3, and ZFHX3) and eight rare de novo variants in eight additional genes (CELSR1, CLP1, GPR133, HPS3, MTA3, PLEC, STAB1, and PPIP5K2). Through personal communication during the project, we identified an additional EA/TEF case-parent trio with a rare de novo variant in ZFHX3. In silico prediction analysis of the identified variants and comparative analysis of mouse transcriptome data of esophageal tissue obtained at E8.5, E12.5, and postnatal prioritized CHD7, TRPS1, and ZFHX3 as EA/TEF candidate genes. Re-sequencing of ZFHX3 in additional 192 EA/TEF patients did not identify further putative EA/TEF-associated variants. CONCLUSION: Our study suggests that rare mutational de novo events in genes involved in foregut development contribute to the development of EA/TEF.

BACKGROUND: Esophageal atresia with or without tracheoesophageal fistula (EA/TEF) represents the most common developmental malformation of the upper digestive tract. It is classified into six subtypes according to the classification of Vogt, depending on anatomical variation of this malformation. Around 50% of the patients with EA/TEF present additional anomalies, which often influence, next to the EA/TEF subtype, the overall prognosis of EA/TEF newborns. Here, we investigated the association of the different EA/TEF subtypes with co-occurring congenital anomalies in EA/TEF patients and demonstrate their implications for postnatal diagnostic workup. MATERIALS AND METHODS: We investigated 333 patients of a large German multicenter study born between 1980 and 2012. After evaluation of all available clinical records, 235 patients were included in our analysis. We compared our results with existing data. RESULTS: The highest risk for co-occurring anomalies was seen in patients with most common Vogt 3b (p = 0.024), especially for additional gastrointestinal anomalies (p = 0.04). Co-occurring anomalies of the skin were significantly more common in patients with subtype Vogt 2 (p = 0.024). A significant correlation was observed for an impaired neurodevelopmental outcome and EA/TEF Vogt 3a (p = 0.041). Patients with EA/TEF showed a higher risk to present with any additional congenital anomaly compared with the general population (p < 0.001). CONCLUSION: Our results warrant thorough clinical workup for gastrointestinal anomalies especially in patients with Vogt 3b. Moreover, it might be necessary to focus on a thorough aftercare for neurocognitive development in patients with Vogt 3a. The here presented observations need to be confirmed by future studies.

Background The short- and long-term surgical results in patients with esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) have been described in depth from a physician's perspective. Contrarily, the perception and coping strategies of affected patients and their parents have rarely been reported. The aim of this study was to generate data on this matter. Patients and Methods A total of 154 patients who had operative reconstruction for EA between 1971 and 2012 were evaluated for demographic data, surgical technique, affection of daily life, and coping strategies. Results Gastroesophageal reflux (GER) symptoms were reported in 59% of cases with 33% requiring fundoplication. Regular bougienages of anastomotic strictures were necessary in 68% with 36% requiring repeated dilatations in the first postoperative year. Enteral nutrition via a nasogastric tube was performed in 66% after surgery. In 40%, the tube was needed until their sixth week of life. In 25%, nutritional support was necessary more than 1 year out of surgery. Quality of life in general was felt to be impaired according to the patients' parents in 50%. Regarding medical advice about long-term morbidities, more than 50% of the parents felt insufficiently advised. There were no statistical differences between the EA/TEF subtypes regarding GER symptoms, frequency of esophageal dilatations, eating behaviors, or support of the parents in feeding management. Conclusion Our observations indicate that a high percentage of EA/TEF patients and families require more intensive aftercare and support during the first year following primary reconstruction than previously thought. We observed a higher need for adequate parental information on long-term complications of their children compared with current practice.

BACKGROUND: Esophageal atresia with/without trachea-esophageal fistula (EA/TEF) denotes a spectrum of severe congenital malformations. The aim of this systematic study was to determine both the recurrence risk for EA/TEF, and the risk for malformations of the VATER/VACTERL association spectrum, in first-degree relatives of patients with isolated EA/TEF. METHODS: A total of 108 unrelated patients with isolated EA/TEF were included. These individuals had 410 first-degree relatives including 194 siblings. The presence of EA/TEF and malformations of the VATER/VACTERL association spectrum in relatives was systematically assessed. Data from the EUROCAT network were used for comparison. RESULTS: None of the first-degree relatives displayed any form of EA/TEF. In two families, a first-degree relative presented with malformations from the VATER/VACTERL association spectrum. However, no increase in the risk for malformations of the VATER/VACTERL association spectrum was found compared with the control cohort (p = 0.87). In three families, one more distantly related relative presented with EA/TEF. CONCLUSION: In contrast to previous studies, our results suggest a very low recurrence risk for isolated EA/TEF and/or for malformations of the VATER/VACTERL association spectrum among first-degree relatives.
