Individual gut-directed hypnotherapy (HT) is effective in pediatric irritable bowel syndrome (IBS) and functional abdominal pain or functional abdominal pain syndrome (FAP[S]). It is, however, unavailable to many children.OBJECTIVE To compare the effectiveness of HT by means of home-based self-exercises using a CD with that of individual HT (iHT) performed by qualified therapists. DESIGN, SETTING, AND PARTICIPANTSThis noninferiority randomized clinical trial with a follow-up of 1 year after the end of treatment was conducted from July 15, 2011, through June 24, 2013, at 9 secondary and tertiary care centers throughout the Netherlands. A total of 303 children were eligible to participate. Of those, 260 children (aged 8-18 years) with IBS or FAP(S) were included in this study. Children were randomized (1:1 ratio) to home-based HT with a CD (CD group) or iHT performed by qualified therapists (iHT group). No children withdrew from the study because of adverse effects. INTERVENTIONSThe CD group was instructed to perform exercises 5 times per week or more for 3 months. The iHT group consisted of 6 sessions during 3 months. MAIN OUTCOMES AND MEASURESPrimary outcomes were treatment success directly after treatment and after 1-year follow-up. Treatment success was defined as a 50% or greater reduction in pain frequency and intensity scores. The noninferiority limit was set at 50% treatment success in the CD group, with a maximum of 25% difference in treatment success with the iHT group after 1-year follow-up. Modified intention-to-treat analyses were performed.RESULTS A total of 132 children were assigned to the CD group and 128 to the iHT group; 250 children were analyzed (126 in the CD group and 124 in the iHT group) (mean [SD] age, 13.4 [2.9] years in the CD group and 13.3 [2.8] years in the iHT group; 94 female [74.6%] in the CD group and 85 [68.5%] in the iHT group). Directly after treatment, 46 children (36.8%) in the CD group and 62 (50.1%) in the iHT group were successfully treated. After 1-year follow-up, the 62.1% treatment success in the CD group was noninferior to the 71.0% in the iHT group (difference, −8.9%; 90% CI, −18.9% to 0.7%; P = .002). CONCLUSIONS AND RELEVANCELong-term effectiveness of home-based HT with a CD is noninferior to iHT performed by therapists in pediatric IBS or FAP(S). Treatment with hypnosis using a CD provides an attractive treatment option for these children.

Serious and fatal complications after button battery ingestion are increasing worldwide. The aim of this study is to describe serious complications after battery ingestion in children in the Netherlands.All pediatric gastroenterologists in the Netherlands performing upper endoscopies were asked to report all serious complications after battery ingestion in children (0–18 years) between 2008 and 2016 retrospectively.Sixteen serious complications were reported: death after massive bleeding through esophageal-aortal fistula (n = 1), esophageal-tracheal fistula (n = 5), stenosis after (suspected) perforation and mediastinitis (n = 5), (suspected) perforation and mediastinitis (n = 3), vocal cord paralysis (n = 1), and required reintubation for dyspnea and stridor (n = 1). The median time interval between ingestion and presentation was 5 (IQR 2–258) h. All children were ≤ 5 (median 1.4; IQR 0.9–2.1) years. Vomiting (31.3%), swallowing/feeding problems (31.3%), and fever (31.3%) were the most common presenting symptoms; however, 18.8% of the patients were asymptomatic (n = 1 missing). All batteries were button batteries (75% ≥ 20 mm; 18.8% < 20 mm; n = 1 missing). The batteries were removed by esophagogastroduodenoscopy (50%) and rigid endoscopy (37.5%) or surgically (12.5%).Conclusion: Sixteen serious complications occurred after small and large button batteries ingestion between 2008 and 2016 in both symptomatic and asymptomatic children in the Netherlands. Therefore, immediate intervention after (suspected) button battery ingestion is required. What is Known: • Button battery ingestion may result in serious and fatal complications. • Serious and fatal complications after button battery ingestion are increasing worldwide. What is New: • Sixteen serious complications after button battery ingestion occurred during 2008–2016 in children in the Netherlands. • Serious complications were also caused by small batteries (< 20 mm) in the Netherlands and also occurred in asymptomatic Dutch children.

Antibiotic treatment is common practice in the neonatal ward for the prevention and treatment of sepsis, which is one of the leading causes of mortality and morbidity in preterm infants. Although the effect of antibiotic treatment on microbiota development is well recognised, little attention has been paid to treatment duration. We studied the effect of short and long intravenous antibiotic administration on intestinal microbiota development in preterm infants. Faecal samples from 15 preterm infants (35 ± 1 weeks gestation and 2871 ± 260 g birth weight) exposed to no, short (≤ 3 days) or long (≥ 5 days) treatment with amoxicillin/ceftazidime were collected during the first six postnatal weeks. Microbiota composition was determined through 16S rRNA gene sequencing and by quantitative polymerase chain reaction (qPCR). Short and long antibiotic treat ment significantly lowered the abundance of Bifidobacterium right after treatment (p = 0.027) till postnatal week three (p = 0.028). Long treatment caused Bifidobacterium abundance to remain decreased till postnatal week six (p = 0.009). Antibiotic treatment was effective against members of the Enterobacteriaceae family, but allowed Enterococcus to thrive and remain dominant for up to two weeks after antibiotic treatment discontinuation. Community richness and diversity were not affected by antibiotic treatment, but were positively associated with postnatal age (p < 0.023) and with abundance of Bifidobacterium (p = 0.003). Intravenous antibiotic administration during the first postnatal week greatly affects the infant’s gastrointestinal microbiota. However, quick antibiotic treatment cessation allows for its recovery. Disturbances in microbiota development caused by short and, more extensively, by long antibiotic treatment could affect healthy development of the infant via interference with maturation of the immune system and gastrointestinal tract.Electronic supplementary materialThe online version of this article (10.1007/s10096-018-3193-y) contains supplementary material, which is available to authorized users.

ObjectiveIn newly diagnosed paediatric patients with moderate-to-severe Crohn’s disease (CD), infliximab (IFX) is initiated once exclusive enteral nutrition (EEN), corticosteroid and immunomodulator therapies have failed. We aimed to investigate whether starting first-line IFX (FL-IFX) is more effective to achieve and maintain remission than conventional treatment.DesignIn this multicentre open-label randomised controlled trial, untreated patients with a new diagnosis of CD (3–17 years old, weighted Paediatric CD Activity Index score (wPCDAI) >40) were assigned to groups that received five infusions of 5 mg/kg IFX at weeks 0, 2, 6, 14 and 22 (FL-IFX), or EEN or oral prednisolone (1 mg/kg, maximum 40 mg) (conventional). The primary outcome was clinical remission on azathioprine, defined as a wPCDAI <12.5 at week 52, without need for treatment escalation, using intention-to-treat analysis.Results100 patients were included, 50 in the FL-IFX group and 50 in the conventional group. Four patients did not receive treatment as per protocol. At week 10, a higher proportion of patients in the FL-IFX group than in the conventional group achieved clinical (59% vs 34%, respectively, p=0.021) and endoscopic remission (59% vs 17%, respectively, p=0.001). At week 52, the proportion of patients in clinical remission was not significantly different (p=0.421). However, 19/46 (41%) patients in the FL-IFX group were in clinical remission on azathioprine monotherapy without need for treatment escalation vs 7/48 (15%) in the conventional group (p=0.004).ConclusionsFL-IFX was superior to conventional treatment in achieving short-term clinical and endoscopic remission, and had greater likelihood of maintaining clinical remission at week 52 on azathioprine monotherapy.Trial registration numberClinicalTrials.gov Registry (NCT02517684).

WHAT'S KNOWN ON THIS SUBJECT:Chronic constipation is a common problem in childhood. In two randomized trials in adults with irritable bowel syndrome and constipation, and 1 in constipated women with a defecation frequency Ͻ3 times per week, a significant increase was shown in stool frequency in the probiotic group who used Bifidobacterium lactis DN-173 010 compared with the control group in subjects who had Ͻ3 stools per week. WHAT THIS STUDY ADDS:In constipated children, the fermented dairy product that contained B lactis strain DN-173 010 increased stool frequency, but this increase was comparable to that of the control group. There is currently insufficient evidence to recommend fermented dairy products that contain B lactis strain DN-173 010 for these patients. abstract BACKGROUND: Constipation is a frustrating symptom affecting 3% of children worldwide. A fermented dairy product containing Bifidobacterium lactis strain DN-173 010 was effective in increasing stool frequency in constipated women. Our aim was to assess the effects of this product in constipated children. METHODS: In this prospective randomized, double-blind, controlled trial, 159 constipated children (defecation frequency Ͻ 3 times per week) were randomly allocated to receive either a fermented dairy product that contains B lactis DN-173 010 (n ϭ 79) or a control product (n ϭ 80) twice a day for 3 weeks. The primary endpoint was the change in stool frequency from baseline to after 3 weeks of product consumption. Analyses were by intention to treat. RESULTS: Eleven children did not return to any follow-up visit (5 in the probiotic group, 6 in the control group) and were therefore excluded from the final analysis. Thus, 74 children in each group were analyzed. The change in stool frequency from baseline to after 3 weeks of product consumption increased in both groups, but the difference was not statistically significant (2.9 Ϯ 3.2 in probiotic group versus 2.6 Ϯ 2.6 in control group, P ϭ .35). There were no serious adverse events. CONCLUSIONS: In constipated children, the fermented dairy product containing B lactis strain DN-173 010 did increase stool frequency, but this increase was comparable in the control group. There is currently not sufficient evidence to recommend fermented dairy products containing B lactis strain DN-173 010 in this category of patients. Future studies should focus on whether a longer period of probiotic products is more effective in children who have a short history of constipation.
