Objective: In the TRANS–IBD clinical trial, the outcomes are measured with selected validated questionnaires. Cross-cultural and age adaptations of the Self-Efficacy Scale for adolescents and young adults (IBD–SES), the Transition Readiness Assessment Questionnaire (TRAQ), and the Self-Management and Transition Readiness Questionnaire (STARx) were performed. Methods: Linguistic and cultural adaptation was carried out with the usage of reliability coefficients (Cronbach’s α coefficients, Spearman’s rank correlation), and with confirmatory factor analysis (CFA; root Mean Square Error of Approximation [RMSEA], Comparative Fit Index [CFI], and Tucker-Lewis Index [TLI]). Results: 112 adolescents participated in the study (45.5% male, mean age 17 ± 1.98 years). CFA was acceptable in the IBD–SES and the TRAQ. Internal consistency was acceptable in IBD–SES and good in TRAQ (0.729; 0.865, respectively). Test–retest reliability was good in IBD–SES, but below the acceptable threshold in TRAQ (ρ = 0.819; ρ = 0.034). In STARx tools, RMSEA showed poor fit values, CFI and TLI were below acceptable fit values, and internal consistency was not satisfied (0.415; 0.693, respectively), while test–retest reliabilities were acceptable (ρ = 0.787; ρ = 0.788, respectively). Conclusions: Cross-cultural, age-specific adaptation was successfully completed with IBD–SES and TRAQ. Those are comparable to the original validated versions. The adaption of the STARx tools was not successful.

Objectives: According to the Porto criteria, upper endoscopy and ileocolonoscopy with histology for patients with pediatric inflammatory bowel disease (pIBD) are recommended with small bowel imaging (SBI). We aimed to evaluate the adherence to the Porto criteria and biopsy sampling practice and to evaluate the diagnostic yield of magnetic resonance enterography (MRE) first time in a nationwide pIBD inception cohort.Methods: Newly diagnosed pIBD cases (ages 0–18 years) are registered in the prospective, nationwide Hungarian Paediatric IBD Registry (HUPIR). We analyzed the diagnostic workup of patients recorded between the 1st of January 2007 and the 31st of December 2016.Results: Data for diagnostic workup was available in 1,523 cases. Forty percent of the cases had complied with the Porto criteria. Adherence to the Porto criteria increased significantly from 20 to 57% (p < 0.0001) between 2007 and 2016. The most frequent reason for the incomplete diagnostic work-up was the lack of small bowel imaging (59%). In 2007, 8% of cases had a biopsy from all segments, and this rate reached 51% by 2016 (p < 0.0001). We analyzed the diagnostic yield of MRE in 113 patients (10.1%), who did not have any characteristic lesion for Crohn's disease. The MRE was positive for the small bowel in 44 cases (39%).Conclusions: Adherence to the Porto criteria increased significantly during the 10-year period. This is the first study that reports multiple biopsy sampling as the less accepted recommendation. The diagnostic yield of MRE in patients without characteristic lesion for Crohn's disease is 39%.

Tracheal agenesis – failure of trachea development - is an extremely rare and severe congenital disorder involving the respiratory system and in most cases it is associated with other abnormalities. Three anatomic types of tracheal agenesis were described by Floyd. Antenatal diagnosis is difficult, especially if it is combined with a tracheo-oesophageal fistula. We report a postnatally diagnosed case of a female newborn with Type II tracheal agenesis. Polyhydramnios and right upper limb anomaly were diagnosed prenatally. Only typical postnatal clinical signs, such as severe asphyxia with strong respiratory efforts, no audible cry, failed endotracheal intubation and no palpable tracheal tissue on the neck aroused suspicion of tracheal agenesis. Despite the few published cases when antenatal diagnosis of tracheal agenesis and series of heroic postnatal surgical interventions resulted in few years’ survival, tracheal agenesis is still considered as a lethal condition. Possibilities of antenatal diagnosis, postnatal management and therapeutic options are discussed.

Introduction Inflammatory bowel diseases (IBD) are among the most common chronic illnesses diagnosed in childhood. Transition from paediatric to adult care is a crucial phase. The implementation of joint visits during the transition period in IBD is widely recommended, however, strong evidence supporting their benefit is still missing. In this trial, we aim to prove the superiority of joint visits compared with usual care in improving transition outcomes of adolescents with IBD.Methods and analysis This is a randomised controlled two-arm multicentre trial. A minimum of 160 adolescents with IBD aged between 16.75 and 17 years will be recruited from Hungarian tertiary IBD centres. After randomisation, eligible subjects in the intervention arm attend a total of four joint visits with adult and paediatric gastroenterologist between the ages of 17 and 18. In the control arm, adolescents meet only the paediatric gastroenterologist, but there is a balanced consultation between the two gastroenterologist regarding the patient’s treatment plan. Patients in both groups receive the same training and education, the only determinative difference between the two arms is the presence of the adult gastroenterologist at the joint visits. Data will be collected at inclusion, at transfer and 12 months post-transfer. Primary outcome is the change in health-related quality of life measured with the IMPACT-III questionnaire at 1 year after transfer. Secondary outcomes include the number of patients not lost to follow-up, healthcare utilisation, disease activity, medication adherence, self-efficacy, transition readiness and patient’s satisfaction. To compare the results of the two patient groups, two-sample T-test and Mann-Whitney test will be applied.Ethics and dissemination The Scientific and Research Ethics Committee of the Hungarian Medical Research Council approved this study (50457-2/2019/EKU). Findings will be disseminated at conferences and in medical journals.Trial registration number NCT04290156.
