    ABSTRACT: Background: Previous studies of endoscopic adverse events (AE) in children have focused on intraprocedural and short-term outcomes, such as bleeding, perforation and infection, and may underestimate the incidence of AE's. Objective: To conduct a comprehensive study of post-endoscopic AE in children, categorizing them by the level of intervention required. Design: Prospective observational study tracking AE's in pediatric patients within 72 hours of an endoscopic procedure. Setting: Single center study performed at an academic, tertiary care, free-standing children's hospital over a 48 month period, from July 2010 through June 2014. Patients and interventions: Out of 9,577 pediatric endoscopic procedures, cases identified as having an AE during or following endoscopy were subject to additional chart review for abstraction of relevant data. Main outcome measurements: Type, severity and subsequent interventions of AE's were the primary outcome measures. Events were categorized by severity grade, with grade 1 no intervention, grade 2 outpatient evaluation, grade 3 hospitalization or repeat endoscopy, grade 4 surgery or ICU admission, and grade 5 death. Results: In total, 249 endoscopic AE's were recognized out of 9577 procedures performed, yielding a rate of 2.6%. Of these, 160 were identified to result in medical evaluation and costs (≥ grade 2) for a rate of 1.7%. Rates of endoscopic AE after advanced or interventional endoscopic procedures were higher, with 65/1167 events, resulting in an AE rate of 5.6%, with a rate of ≥ grade 2 of 4.37%. There were 10 cases of significant bleeding (0.1%), 9 cases of infection (0.09%) and 12 cases of perforation (0.13%), primarily occurring with advanced/interventional procedures. Limitations: Single center study, lack of standardized criteria for ED referral CONCLUSION:: AE's presenting within 72 hours of endoscopy and resulting in medical intervention, occur more commonly than previously recognized in children. Standardized post-endoscopy surveillance systems and definitions of AE's are needed.

    ABSTRACT: Objective: Ataxia telangiectasia (A-T) is a rare genetic multiorgan disease. Although gastrointestinal involvement is known, hepatic involvement in A-T has not been investigated. We aimed to study the hepatic involvement in a large cohort of A-T patients. Methods: A retrospective review of patients, followed from January 1986 to January 2015 at a National A-T Center. Clinical data including demographic, genetic, laboratory, nutritional, radiographic and histological data, were retrieved. Results: Fifty three patients, 27 (49%) males, aged 14.6±5.2 years (range 5.9-26.1 years), were included. Twenty three patients (43.4%), age 9.9±5.1years, had consistently abnormal liver enzymes. The mean enzyme levels were: ALT 76.8±73.8 IU/l, AST 70±50 IU/l, AP 331±134 IU/l, and GGT 114.7±8 IU/l. Evaluation of other etiology of liver disease was negative. Ultrasonography revealed fatty liver in 9 of them (39%). Liver biopsy was performed in 2 patients, revealing mild -moderate steatosis in both, and fibrosis in one patient. Progression to advanced liver disease occurred in 2/23 (9%) patients within 2-5 years. Dyslipidemia was significantly associated with abnormal liver enzymes: 3/30 (10%) of patients without vs. 10/23 (45.5%) of patients with abnormal liver enzymes, respectively (p<0.05, Fisher exact test). No correlation was found between hepatic involvement and HbA1C, gender, presence of malignancy or type of mutation. Conclusions: Abnormal liver enzymes and fatty liver are common in A-T patients, and may progress to advanced liver disease at a young age. These findings are novel, and implicate that A-T patients with abnormal liver enzymes should be evaluated for the presence of liver disease.

    ABSTRACT: Background: Biliary atresia (BA) is a leading cause of liver failure and liver transplantation in pediatrics. BA manifests by three weeks of life with jaundice and pale stools. Delayed diagnosis and surgical intervention with Kasai portoenterostomy (KP) after three months of age is significantly associated with poor prognosis for native liver survival. A national Taiwan infant stool color card (SCC) screening program has entirely eliminated late KP > 90 days of age and improved native liver survival. A recent large-scale prospective cohort study in British Columbia, Canada, indicated that distribution of SCC on the maternity ward was feasible, led to high utilization rate, and was cost-effective. The aim of the present study was to assess the generalizability of this screening strategy in another Canadian jurisdiction with a different socio-demographic profile. Methods: An SCC was distributed to families of newborns discharged at St. Mary's Hospital Center, Montreal, Quebec. Families were instructed to monitor their infant's stool color for 21 days, and then complete and mail the SCC to the study center. Phone surveys to families who did not return cards were used to estimate total card utilization rate. Results: 2246 infants were eligible for inclusion; 99.9% were enrolled. Mail SCC return rate was 63.3%. No cases of BA were identified. All 118 families who completed the phone survey reported that they had utilized the SCC. Conservative and optimistic estimates for total card utilization rates were 82% and 100% respectively. Conclusions: The high enrollment and utilization rates in this screening study strongly support the feasibility of implementing a Canadian SCC screening program to improve outcomes of children with BA.

    ABSTRACT: Background: Abdominal pain-predominant functional gastrointestinal disorders (AP-FGIDs) are a common public health problem in children. The precise aetiology of AP-FGIDs is far from clear. Psychological stress and all forms of child abuse are known predisposing factors to develop AP-FGIDs. The main objective of this study is to study the association between adverse life events (ALEs) and development of AP-FGIDs. Methods: A cross sectional, school based study was conducted in Gampaha district of Sri Lanka. All children aged 13-18 years were recruited from four randomly selected semi-urban schools in the district after obtaining consent from parents, school administration and children themselves. A translated and validated, self-administered questionnaire consisting of four parts was used for data collection. Part I was the Rome III questionnaire for functional gastrointestinal disorders, self-report form for children above 10 years. Part II was a questionnaire on exposure to adverse life events. Part III was the Sinhala (the native language) version of the PedsQL, Pediatric Quality of Life Inventory 4.0 (Generic Core Scales). Part IV was the Child Somatization Inventory. The questionnaire was administered under examination setting to ensure confidentiality and privacy. Research assistant were present during filling the questionnaire for provide assistance and verifications. AP-FGIDs were defined using the Rome III criteria. Results: A total of 1792 children were included in the analysis (males 975 [54.4%], mean age 14.4 years, SD 1.3 years years). Out of them, 305 (17.0%) had AP-FGIDs. ALEs that showed a significant association with AP-FGIDs include, parental substance abuse (25.1% vs. 16.0% in controls, p = 0.015) and domestic violence (28.5% vs. 16.1%, p = 0.02). Children with AP-FGIDs exposed to ALEs have a higher somatization index compared to children not exposed to ALEs (16.9 vs. 13.4, p = 0.003), and a lower overall health-related quality of life (HRQoL) score (81.8 vs. 85.1, p = 0.02). The scores they obtained for psycho-social (86.4 vs. 92.4, p < 0.0001) and emotional (72.5 vs. 77.7, p = 0.03) domains of the HRQoL were also lower than that of children with no such experiences. Conclusions: Exposure to ALEs predispose children to develop AP-FGIDs. Experience of childhood ALEs deleteriously affects the HRQoL and somatization of children with AP-FGIDs.

    ABSTRACT: Introduction: The fatigue rate index (FRI) is a parameter in anorectal manometry (ARM) to assess sustained voluntary contraction, considering the squeeze pressure and fatigability of the external anal sphincter. It is used in adults to detect fecal incontinence even in patients who present normal squeeze pressures. The FRI in adult patients with functional constipation is similar to controls.The aim of this preliminary study was to evaluate the feasibility and values of FRI in children with retentive fecal incontinence secondary to functional constipation. Methods: This retrospective study evaluated 105 ARM performed from Jan 2014 to Apr 2015. 42 patients were selected (were able to perform a voluntary contraction and had no co-morbidities other than functional constipation). 14 of those (33,3%) collaborated in sustaining contraction for 40 seconds (s), allowing the evaluation of the FRI. Patients with retentive fecal incontinence secondary to functional constipation (n = 7, aged 6 to 13 years, 6 boys) were our interest group. Patients with functional constipation without fecal incontinence (n = 7, aged 6 to 13 years, 4 boys) were considered a reference group. The ARM were performed with a radial eight-channel perfusion catheter (Dynamed™, São Paulo, Brazil) and the FRI was calculated (Proctomaster 6.4) in the first 20 s and overall 40 s of sustained voluntary contraction. Results: In the first 20 s of contraction, the fecal incontinence group showed a significantly higher mean FRI (2.48 ± 1.39 min) compared to the reference group (1.13 ± 0.72 min, p = 0.042), which was not observed in the 40 s due to less uniform contraction. The anal resting pressure was higher in fecal incontinence group (76.83 mmHg) than in the reference group (54.13 mmHg), but the statistical study did not reach significance (p = 0.051). Discussion: The mean FRI obtained in this study is lower than the reported in constipated adults (2,8 min).We hypothesized that the higher FRI found in children with retentive fecal incontinence may be associated with retention behavior in cases of severe constipation and to higher anal resting pressure in patients with retentive incontinence. Conclusions: FRI may be feasible in older children, its reference value may be lower than in adults and it is higher among patients with retentive incontinence.

    ABSTRACT: Objectives: This study aimed to investigate histologic features of children with RAP undergoing upper gastrointestinal endoscopy, after exclusion of common organic disease. Methods: Children referred for endoscopy were prospectively enrolled at a single tertiary center between 2008 and 2010, after obtaining informed consent. Cases were defined as children with clinical diagnosis of RAP, as opposed to controls with suspicion of organic disease. Gastric and duodenal biopsies were analysed by pathologists blinded to indication. Demographic and clinical variables, H. pylori infection, biochemical, endoscopic and pathologic results were compared between cases and controls. Results: A total of 101 children were included after exclusion of villous enteropathy (n = 6) and parasitic, rotaviral or salmonella enteritis (n = 14), resulting in 72 cases and 29 controls. There were no significant differences in demographics, clinical symptoms, H. pylori infection and endoscopic findings between cases and controls. Duodenal eosinophil counts per 5 HPF were significantly increased in cases vs. controls (median (IQR) 86 (62-114) vs. 49 (31-88); p < 0.001) and did not differ regarding age, gender and H. pylori. Intraepithelial lymphocytes per 100 enterocytes were similar in cases vs. controls (19 (15-25) vs. 18 (14-23); p = 0.89) with ≥ 25 in 25% of cases. Duodenal eosinophilia was equally observed in H. pylori negative cases (n = 50) vs. controls (n = 19) (87 (61-119) vs. 53 (36-95); p = 0.01), as well as positive cases (n = 21) vs. controls (n = 10) (85 (55-105) vs. 42 (18-65); p = 0.03). Logistic regression yielded an adjusted odds ratio of 1.23 (95% CI 1.08-1.40) for duodenal eosinophilia in RAP. Conclusions: Children with a clinical diagnosis of RAP have marked duodenal eosinophilia, independent of H. pylori infection, suggesting the role of unknown infectious or allergic triggers in the pathogenesis of functional gastrointestinal disorders in childhood. Further research is needed on the diagnostic and therapeutic benefits of targeting duodenal eosinophilia.

    ABSTRACT: Introduction: Some patients with myelomeningocele need bladder augmentation (augmentation cystoplasty). The aim of this study was to evaluate the relationship between the bladder augmentation and the rectoanal inhibitory reflex (RAIR) modulation in patients with myelomeningocele. The modulation of the anorectal inhibitory reflex in accord the use of oxybutynin chloride was also evaluated. Methods: It is a cross-sectional and comparative study. We studied a convenience sample consisting of 24 children and adolescents with myelomeningocele aged between 4 and 18 years. Ten of these 24 patients had surgery to expand the bladder. Anorectal manometry of perfusion were performed with 8-channel radial catheter (Dynamed®) in latex free protocol. The evaluation of the (RAIR) modulation was determined by inflating the balloon with 20 mL of air in rectal. The RAIR modulation was determined by duration (seconds) and amplitude (% relaxation) of RAIR. Results: RAIR was present in all the patients. The duration of the RAIR (seconds) with 20 mL and 40 mL was similar in the both groups, with or without bladder augmentation (27.11 ± 11.95; 27.37 ± 9.29; p = 0.953 and 30.32 ± 7.30; 32.08 ± 10.13, p = 0.653).The RAIR amplitude with 20 mL and 40 mL was higher in the patients with bladder augmentation than in patients without bladder augmentation (63.87 ± 24.58; 82.31 ± 15.94, p = 0.036 and 68.06 ± 14.80;88.93 ± 16.31, p = 0.004). The patients who used oxybutynin chloride presented higher amplitude (% relaxation) in relation those did not used this drug, with 20 mL (80.91 ± 15.37 and 65.21 ± 25.73; p = 0.074) and 40 mL (85.78 ± 15.96 and 73.05 ± 19.29; p = 0.084), however, the statistic evaluation did not reach significance. Conclusions: The RAIR modulation is different between patients with and without bladder augmentation. The use of oxybutynin chloride also appears to interfere in the RAIR, increasing its amplitude.
