Do Children Just Grow Out of Irritable Bowel Syndrome?

OBJECTIVE: Few data exist on natural history of irritable bowel syndrome (IBS) in children; therefore we investigated symptoms evolution over time in a cohort of children with IBS. STUDY DESIGN: In this observational, single-center study, we prospectively enrolled newly diagnosed children with IBS and reassessed them after 24 months. At both time points, patients completed a symptoms questionnaire, and a score of stool consistency was obtained. The therapeutic strategy adopted was also recorded. RESULTS: Eighty-three children (age 11 years, range, 4-16.6 years; 53 males) completed the study. Forty-seven (56.6%) patients received no medical treatment, whereas polyethylene glycol, probiotics, and trimebutine were prescribed to 9 (10.8%), 24 (28.9%), and 3 (3.6%) subjects, respectively. Twenty-four months after diagnosis, 48 children (57.8%) reported resolution of symptoms (P <.001), without differences between sexes (P = .35) or among IBS subtypes (P = .49). Of these, 30 (62.5%) had been only reassured and 18 (37.5%) had been prescribed medical treatment (P = .26). Despite not being statistically significant, symptoms resolution was more common in patients receiving no medical treatment than in those receiving probiotics (63.8% vs 41.6%, P = .08). Among patients with constipation-IBS, no difference was found in symptoms resolution between patients receiving polyethylene glycol and those receiving no medical treatment (67% and 40%, respectively, P = 1). CONCLUSIONS: Children with IBS are likely to show spontaneous symptoms resolution over a 24-month follow-up, regardless of sex, age, impact of symptoms on daily activities, and IBS subtypes.

Effect of magnesium alginate plus simethicone on gastroesophageal reflux in infants.

OBJECTIVES: Gastroesophageal reflux (GER) is a frequently occurring condition in infants capable of causing distressing symptoms. The aim of our study is to evaluate the efficacy of Mg alginate plus simethicone (Gastrotuss Baby, DMG Italia SRL, Pomezia, Italy), compared with rice-starch-thickened formula or with reassurance alone, in the treatment of GER in infants. METHODS: The present randomized controlled trial was conducted in full-term infants affected by symptoms suggestive of GER, evaluated through a validated questionnaire (Infant Gastroesophageal Reflux Questionnaire Revised). The patients were randomized into 3 groups according to treatment (group A: Mg alginate plus simethicone; group B: thickened formula; group C: reassurance with lifestyle changes). Evaluation of symptom scores was performed after 1 month (T1) and 2 months (T2). RESULTS: A total of 64 (85.3%) of 75 enrolled infants (median age 5 months; range 1-10) concluded the study. After 1 month of treatment (T1), infants treated with Mg alginate plus simethicone showed a statistically significant improvement in symptoms compared with the thickened formula and reassurance (P < 0.03, <0.0001, respectively). At the end of the study, all 3 groups of patients showed a significant reduction in symptom scores (P < 0.002, <0.038, <0.03, respectively). Median symptom score values were more significantly reduced in group A than in group B and in group C (group A vs group B P < 0.002; group A vs group C P < 0.0001; group B vs group C P < 0.001). CONCLUSIONS: Mg alginate plus simethicone seems to be more efficacious on GER symptom scores than thickened formula and reassurance with lifestyle changes alone.

Stool consistency, but not frequency, correlates with total gastrointestinal transit time in children.

OBJECTIVES: To evaluate the correlation between stool characteristics (consistency and frequency) and gut transit time in children and to determine whether the Bristol Stool Form Scale is a reliable method of assessing intestinal transit rate in children. STUDY DESIGN: From March 2011 to March 2012, 44 children (25 boys and 19 girls, mean age 7.8 years) with a diagnosis of functional constipation and 36 healthy, nonconstipated children (17 boys and 19 girls, mean age 7.6 years) were enrolled. All participants maintained a 1-week stool diary, recording the time and date of every bowel movement and stool form, and then completed a validated questionnaire on functional constipation according to Rome III criteria. Whole gut transit time (WGTT) was then assessed using the radiopaque markers test. RESULTS: There was a significant correlation between stool form and WGTT in both constipated and nonconstipated children (correlation coefficient -0.84, P<.001). By contrast, there was no correlation between either stool frequency and WGTT or stool frequency and stool form. Multivariate logistic regression analysis, using WGTT as a dependent variable, showed that the sole variable significantly associated with WGTT was stool form (regression coefficient 2.9, OR 18.4, 95% CI 5.4-62.5, P<.001). CONCLUSION: In this prospective, observational, case-control study, we show that stool form, as measured by the Bristol Stool Form Scale, rather than stool frequency, correlates with WGTT in both constipated and nonconstipated children.

Does cow's milk protein elimination diet have a role on induction and maintenance of remission in children with ulcerative colitis?

AIM: Aims of this study were to evaluate the efficacy of a cow's milk protein (CMP) elimination diet on induction and maintenance of remission and to define association with atopy in children with ulcerative colitis (UC). METHODS: Twenty-nine consecutive patients (mean age: 11.2 years; range: 4.6-17 years; F/M: 15/14) with newly diagnosed UC were randomized either to receive a CMP elimination diet (n = 14) or to continue a free diet (n = 15) associated with concomitant steroid induction and mesalazine maintenance treatment. Children were prospectively evaluated at four time points: within 1 month, 6 months and 1 year after diagnosis or at the time of relapse. RESULTS: Twenty-five of the 29 enrolled patients responded to the UC induction therapy with a complete remission (86.2%), 13 belonging to CMP elimination diet group and 12 to free diet group (p = 0.59). Overall, our data showed that 7 of 13 (53.8%) patients treated with CMP elimination diet and 8 of 15 (53.3%) patients on free diet and UC therapy relapsed within 1 year of follow-up (p = 1). CONCLUSIONS: In conclusion, data of this paediatric, randomized trial suggest that CMP elimination has no role in the management of UC in non-sensitized children.

Seizures in Children with SARS-CoV-2 Infection: Epidemiological, Clinical and Neurophysiological Characterization.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may present with a wide variety of symptoms, including neurological manifestations. We investigated clinical, demographic, laboratory, neurophysiological and imaging characteristics of SARS-CoV-2-positive children with seizures and analyzed differences between children admitted during the periods with prevalent circulation of the Alpha/Delta and Omicron variants, respectively. Patients' characteristics were analyzed according to the presence or absence of seizures and then according to the SARS-CoV-2 variants. Five-hundred and four SARS-CoV-2-positive patients were included: 93 (18.4%) with seizures and 411 (81.6%) without. Patients with seizures were older, had more commonly an underlying epilepsy and had more frequently altered C-reactive protein than those without seizures. Electroencephalography was abnormal in 5/38 cases. According to the SARS-CoV-2 variant, seizures were recorded in 4.7% of the total number of hospitalized patients during the Alpha/Delta period, and in 16.9% of patients admitted during the Omicron period. During the Alpha/Delta variants, seizures were more commonly observed in patients with epilepsy compared to those observed during the Omicron period. Our findings suggest that although SARS-CoV-2 may potentially trigger seizures, they are generally not severe and do not require intensive care admission.

Advances in pediatrics in 2014: current practices and challenges in allergy, gastroenterology, infectious diseases, neonatology, nutrition, oncology and respiratory tract illnesses.

Major advances in the conduct of pediatric practice have been reported in the Italian Journal of Pediatrics in 2014. This review highlights developments in allergy, gastroenterology, infectious diseases, neonatology, nutrition, oncology and respiratory tract illnesses. Investigations endorse a need to better educate guardians and improve nutritional management in food allergy. Management of hyperbilirubinemia in neonates and of bronchiolitis have been improved by position statements of scientific societies. Novel treatments for infant colic and inflammatory bowel diseases have emerged. Studies suggest the diagnostic utility of ultrasonography in diagnosing community-acquired pneumonia. Progress in infectious diseases should include the universal varicella vaccination of children. Recommendations on asphyxia and respiratory distress syndrome have been highlighted in neonatology. Studies have evidenced that malnutrition remains a common underestimated problem in developing countries, while exposure to cancer risk factors in children is not negligible in Western countries. Advances in our understanding of less common diseases such as cystic fibrosis, plastic bronchitis, idiopathic pulmonary hemosiderosis facilitate diagnosis and management. Researches have led to new therapeutic approaches in patent ductus arteriosus and pediatric malignancies.
