| 1 | Visceral hypersensitivity and electromechanical dysfunction as therapeutic targets in pediatric functional dyspepsia显示文摘Functional gastrointestinal disorders(FGID) are common clinical syndromes diagnosed in the absence of biochemical,structural,or metabolic abnormalities. They account for significant morbidity and health care expenditures and are identifiable across variable age,geography,and culture. Etiology of abdominal pain associated FGIDs,including functional dyspepsia(FD),remains incompletely understood,but growing evidence implicates the importance of visceral hypersensitivity and electromechanical dysfunction. This manuscript explores data supporting the role of visceral hypersensitivity and electromechanical dysfunction in FD,with focus on pediatric data when available,and provides a summary of potential therapeutic targets. | John M Rosen Jose T Cocjin Jennifer V Schurman Jennifer M Colombo Craig A Friesen | 2014 | World Journal of Gastrointestinal Pharmacology and Therapeutics2014，5，3： | 16 |
| 2 | Therapeutic effect of melatonin on pediatric functional dyspepsia: A pilot study显示文摘AIM: To study the effectiveness of melatonin vs placebo in children with functional dyspepsia(FD).METHODS: The study was conducted as a double blind, randomized, placebo controlled crossover trial. Subjects were aged 8-17 years and diagnosed with FD based on Rome Ⅲ criteria. All subjects had failed to respond to 4 wk of acid suppression. Subjects receive a continuous two weeks of placebo and a continuous two weeks of melatonin in an order blinded to the participant and the study team. A Global Clinical Score was obtained to assess changes in abdominal pain. Pain was self-reported to be worse(grade 1), no change(grade 2), moderate improvement(grade 3), good(grade 4; minimal pain and not interfering with daily activities), or excellent(grade 5; no pain), respectively. A positive clinical response was defined as a grade 3 or greater response. Subjects wore an actigraph to assess sleep during a one week baseline period and during each treatment period. Subjects' sleep latency and total sleep time were recorded throughout the duration of the study. RESULTS: Fourteen subjects were enrolled and 12 completed the study. One withdrew prior to starting both melatonin and placebo and the other before starting melatonin. A positive clinical response(grade 3-5) was achieved in 42% of subjects on melatonin vs 50% of subjects on placebo(NS). Effect size was calculated and revealed a Cohen's D of 0.343 which demonstrates a medium effect favoring placebo. A grade 4 or grade 5 response was seen in 4 patients on melatonin and 5 patients on placebo. Baseline sleep parameters were in the healthy range with the longest sleep latency being just over 20 min(mean 7.46 ± 8.53 min) and the shortest sleep duration just over 7 h(mean 10.09 ± 2.72 h). The mean latency did not differ between periods of treatment with melatonin as compared to placebo(4.48 ± 6.45 min vs 3.58 ± 4.24 min; NS). The mean sleep duration did not differ between periods of treatment with melatonin as compared to placebo(9.90 ± 3.53 h vs 9.41 ± 2.70 h; NS).CONCLUSION: Melatonin does not appear to have efficacy in relieving pain in unselected pediatric FD. Future studies should consider FD subtypes, pathophysiologic mechanisms, and baseline sleep disturbances. | Katherine Zybach Craig A Friesen Jennifer V Schurman | 2016 | World Journal of Gastrointestinal Pharmacology and Therapeutics2016，7，1： | 6 |
| 3 | Eosinophils and mast cells as therapeutic targets in pediatric functional dyspepsia显示文摘There is an increasing appreciation for the importance of inflammation as a pathophysiologic entity that contributes to functional gastrointestinal disorders including functional dyspepsia(FD).Importantly,inflammation may serve as a mediator between psychologic and physiologic functions.This manuscript reviews the literature implicating two inflammatory cell types,mast cells and eosinophils,in the generation of dyspeptic symptoms and explores their potential as targets for the treatment of FD.There are a number of inciting events which may initiate an inflammatory response,and the subsequent recruitment and activation of mast cells and eosinophils.These include internal triggers such as stress and anxiety,as well as external triggers such as microbes and allergens.Previous studies suggest that there may be efficacy in utilizing medications directed at mast cells and eosinophils.Evidence exists to suggest that combining 'anti-inflammatory' medications with other treatments targeting stress can improve the rate of symptom resolution in pediatric FD. | Craig A Friesen Jennifer V Schurman Jennifer M Colombo Susan M Abdel-Rahman | 2013 | World Journal of Gastrointestinal Pharmacology and Therapeutics2013，4，4： | 4 |
| 4 | Using quality improvement methods to increase use of pain prevention strategies for childhood vaccination显示文摘AIM To increase evidence-based pain prevention strategy use during routine vaccinations in a pediatric primary care clinic using quality improvement methodology.METHODS Specific intervention strategies(i.e.,comfort positioning,nonnutritive sucking and sucrose analgesia,distraction) were identified,selected and introduced in three waves,using a Plan-Do-Study-Act framework.System-wide change was measured from baseline to post-intervention by:(1) percent of vaccination visits during which an evidence-based pain prevention strategy was reported as being used; and(2) caregiver satisfaction ratings following the visit.Additionally,self-reported staff and caregiver attitudes and beliefs about pain prevention were measured at baseline and 1-year post-intervention to assess for possible long-term cultural shifts.RESULTS Significant improvements were noted post-intervention.Use of at least one pain prevention strategy was documented at 99% of patient visits and 94% of caregivers were satisfied or very satisfied with the pain prevention care received.Parents/caregivers reported greater satisfaction with the specific pain prevention strategy used [t(143) = 2.50,P ≤ 0.05],as well as greater agreement that the pain prevention strategies used helped their children's pain [t(180) = 2.17,P ≤ 0.05] and that they would be willing to use the same strategy again in the future [t(179) = 3.26,P ≤ 0.001] as compared to baseline.Staff and caregivers also demonstrated a shift in attitudes from baseline to 1-year post-intervention.Specifically,staff reported greater agreement that the pain felt from vaccinations can result in harmful effects [2.47 vs 3.10; t(70) =-2.11,P ≤ 0.05],less agreement that pain from vaccinations is 'just part of the process' [3.94 vs 3.23; t(70) = 2.61,P ≤ 0.05],and less agreement that parents expect their children to experience pain during vaccinations [4.81 vs 4.38; t(69) = 2.24,P ≤ 0.05].Parents/caregivers reported more favorable attitudes about pain prevention strategies for vaccinations across a variety of areas,including safety,cost,time,and effectiveness,as well as less concern about the pain their children experience with vaccination [4.08 vs 3.26; t(557) = 6.38,P ≤ 0.001],less need for additional pain prevention strategies [3.33 vs 2.81; t(476) = 4.51,P ≤ 0.001],and greater agreement that their doctors' office currently offers pain prevention for vaccinations [3.40 vs 3.75; t(433) =-2.39,P ≤ 0.05].CONCLUSION Quality improvement methodology can be used to help close the gap in implementing pain prevention strategies during routine vaccination procedures for children. | Jennifer Verrill Schurman Amanda D Deacy Rebecca J Johnson Jolynn Parker Kristi Williams Dustin Wallace Mark Connelly Lynn Anson Kevin Mroczka | 2017 | World Journal of Clinical Pediatrics2017，6，1： | 3 |
| 5 | Present state and future challenges in pediatric abdominal pain therapeutics research: Looking beyond the forest显示文摘At the present time, it is nearly impossible to treat pediatric functional gastrointestinal disorders associated with pain in an evidence based fashion. This is due to the overall lack of controlled studies and, even more importantly, the complexity of the contributors to disease phenotype which are not controlled or accounted for in most therapeutic trials. In this manuscript, we review the challenges of defining entry criteria, controlling for the large number of biopsychosocial factors which may effect outcomes, and understanding pharmacokinetic and pharmacodynamic factors when designing therapeutic trials for abdominal pain in children. We also review the current state of pediatric abdominal pain therapeutics and discuss trial design considerations as we move forward. | Craig A Friesen Jennifer V Schurman Susan M Abdel-Rahman | 2015 | World Journal of Gastrointestinal Pharmacology and Therapeutics2015，6，4： | 3 |
