Abstract
Functional constipation is a common problem in childhood and has a great impact on social, physical, and emotional functioning of affected children and their caregivers. No organic cause of the constipation can be found in approximately 95% of children, defining the "so-called" chronic functional constipation. Its prevalence has been reported to range from 0.7 to 29.6%, with a median of 12%. The diagnosis of functional constipation is exclusively clinical based on the pediatric diagnostic Rome criteria for functional gastrointestinal disorders and does not routinely require laboratory and/or radiological investigations. In case of alarm signs and symptoms that may suggest organic diseases, further investigations can be required. The therapeutic management is based on non-pharmacological and pharmacological approaches. Education, demystification of constipation and reward-based toilet training represent the cornerstones of nonpharmacological management. Disimpaction, maintenance treatment and weaning of medication are all elements of pharmacological treatment. Osmotic laxatives, mainly polyethylene glycol (PEG), are considered the first-choice laxative for both disimpaction and maintenance treatment. The aim of this review is to provide pediatric gastroenterologists with a practical tool to support the clinical and therapeutic management of children and adolescents affected by chronic functional constipation.

Ann Saudi Med 2024; 44:111-115. [PMID: 38615181 PMCID: PMC11016151 DOI: 10.5144/0256-4947.2024.111] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Accepted: 01/01/2024] [Indexed: 04/15/2024] Open
Abstract
BACKGROUND Functional constipation (FC) is a common condition in children, and information on the clinical characteristics of FC in Saudi children is scarce. OBJECTIVE Describe the clinical profile of FC in Saudi children. DESIGN Retrospective. SETTING Hospital that provides primary, intermediate and tertiary care. PATIENTS AND METHODS All children diagnosed with FC according to the Rome IV criteria were included and had at least one follow-up clinic visit. Demographic and clinical data collected from medical records included the age at onset, duration of constipation, clinical features, treatment modalities, and factors associated with clinical response. Descriptive statistics and Pearson's chi-squared test were used in the statistical analysis to see how categorical study variables were linked to clinical response. A P value of ≤.05 was used to report statistical significance. MAIN OUTCOME MEASURE Compliance and clinical response to polyethylene glycol (PEG) compared with lactulose. SAMPLE SIZE 370 children from 0.1 to 13 years of age. RESULTS The median (IQR) age of onset was 4 (5) years and less than one year in 14%. The median (IQR) duration of constipation was 4 months (11) and less than two months in 93/370 (25%). Abdominal pain was the most commonly associated feature (44%). Screening for celiac disease and hypothyroidism was negative. A Fleet enema was the most common disimpaction method (54%) and PEG was the most common maintenance medication (63.4%). PEG was significantly better tolerated (P=.0008) and more effective than lactulose (P<.0001). Compliance was the only variable significantly associated with clinical response. CONCLUSIONS PEG was better tolerated and more effective than lactulose in our study, a finding in agreement with the literature. Therefore, PEG should be the drug of choice in the initial management of FC in Saudi children. Prospective studies on the causes of noncompliance are needed to improve the response to treatment. LIMITATIONS The limitations of retrospective design are missing data, recall bias, and hospital-based limitation, such as missing milder cases treated at the outpatient level. However, the sample size of 370 may have minimized these limitations.

High-abundance peaks and peak clusters associate with pharmaceutical polymers and excipients in urinary untargeted clinical metabolomics data: exploration of their origin and possible impact on label-free quantification.

Abstract
Pharmaceutical polymers and excipients represent interesting but often overlooked chemical classes in clinical exposure and bioanalytical research. These chemicals may cause hypersensitivity reactions, they can be useful to confirm exposure to pharmaceuticals, and they may pose bioanalytical challenges, including ion suppression in liquid chromatography-mass spectrometry (LC-MS-)based workflows. In this work, we assessed these chemicals in light of a rather surprising finding presented in two previously published studies, namely that usage of cyclosporine A, an immunosuppressive drug which is known to be cleared through excretion in the bile, explained the largest amount of variance in principal component analysis of urinary LC-SWATH/MS small-molecule profiling data. Specifically, we examined the freely-accessible 24-hour urine metabolomics data of 570 kidney transplant recipients included in the TransplantLines Biobank and Cohort Study (NCT03272841). These data unveiled thousands of high-abundance polymer peaks in some samples, which were associated with the use of the macrogol (i.e., polyethylene glycol) 3350 oral laxative agent. In addition, we found multiple clusters of high-abundance peaks which were linked to the exposure to two pharmaceutical excipients, namely short-chain polyethylene glycol (molecular weight <1000 Da) and polyethoxylated castor oil (also known as Kolliphor® EL or Cremophor® EL). Respectively, these excipients are used in temazepam capsules and cyclosporine A capsules, and the latter provides a plausible explanation for the rather surprising finding that instigated our work. Moreover, such explanation and our findings in general put emphasis on taking into consideration these and other pharmaceutical polymers and excipients when exploring, processing, and interpreting clinical small-molecule profiling data.

Abstract
Objectives This study evaluated the efficacy of Polyethylene glycol 4000 for fecal disimpaction in children with cerebral palsy. Materials & Methods A randomized control trial study was conducted on children with cerebral palsy between February - March 2017 in the pediatric neurology outpatient clinic Dr. Soetomo Hospital. Children aged 2-16 years with fecal impaction randomly assigned into polyethylene glycol 4000 (PEG 4000) and saline enema group. Polyethylene glycol 4000 was given at a dosage of 0.7 g/kg and enema using normal saline 15ml/kg twelve hourly. Constipation was diagnosed using ROME IV criteria, and abdominal palpation identified fecal impaction. Efficacy was evaluated by clinical observation and adverse symptom monitoring. Data were analyzed by statistical software using an independent t-test (p<0,05). Results Thirty-two children were randomized into the study. Muscle relaxant was discovered in 17/32 patients. Sex, age, and body weight were not statistically different between groups. The resolution of fecal impaction was significantly different between PEG 4000 and saline enema (21.69 hours and 39 hours respectively; p=0.001). Application of muscle relaxant and severity of the disease did not involve treatment efficacy. There was no adverse symptom reported during treatment. Conclusion Polyethylene glycol 4000 results in fecal disimpaction faster than enema in constipated children with cerebral palsy.

Abstract
Background Up to 30% of children have constipation at some stage in their life. Although often short-lived, in one-third of children it progresses to chronic functional constipation, potentially with overflow incontinence. Optimal management strategies remain unclear. Objective To determine the most effective interventions, and combinations and sequences of interventions, for childhood chronic functional constipation, and understand how they can best be implemented. Methods Key stakeholders, comprising two parents of children with chronic functional constipation, two adults who experienced childhood chronic functional constipation and four health professional/continence experts, contributed throughout the research. We conducted pragmatic mixed-method reviews. For all reviews, included studies focused on any interventions/strategies, delivered in any setting, to improve any outcomes in children (0-18 years) with a clinical diagnosis of chronic functional constipation (excluding studies of diagnosis/assessment) included. Dual reviewers applied inclusion criteria and assessed risk of bias. One reviewer extracted data, checked by a second reviewer. Scoping review: We systematically searched electronic databases (including Medical Literature Analysis and Retrieval System Online, Excerpta Medica Database, Cumulative Index to Nursing and Allied Health Literature) (January 2011 to March 2020) and grey literature, including studies (any design) reporting any intervention/strategy. Data were coded, tabulated and mapped. Research quality was not evaluated. Systematic reviews of the evidence of effectiveness: For each different intervention, we included existing systematic reviews judged to be low risk of bias (using the Risk of Bias Assessment Tool for Systematic Reviews), updating any meta-analyses with new randomised controlled trials. Where there was no existing low risk of bias systematic reviews, we included randomised controlled trials and other primary studies. The risk of bias was judged using design-specific tools. Evidence was synthesised narratively, and a process of considered judgement was used to judge certainty in the evidence as high, moderate, low, very low or insufficient evidence. Economic synthesis: Included studies (any design, English-language) detailed intervention-related costs. Studies were categorised as cost-consequence, cost-effectiveness, cost-utility or cost-benefit, and reporting quality evaluated using the consensus health economic criteria checklist. Systematic review of implementation factors: Included studies reported data relating to implementation barriers or facilitators. Using a best-fit framework synthesis approach, factors were synthesised around the consolidated framework for implementation research domains. Results Stakeholders prioritised outcomes, developed a model which informed evidence synthesis and identified evidence gaps. Scoping review 651 studies, including 190 randomised controlled trials and 236 primary studies, conservatively reported 48 interventions/intervention combinations. Effectiveness systematic reviews studies explored service delivery models (n = 15); interventions delivered by families/carers (n = 32), wider children's workforce (n = 21), continence teams (n = 31) and specialist consultant-led teams (n = 42); complementary therapies (n = 15); and psychosocial interventions (n = 4). One intervention (probiotics) had moderate-quality evidence; all others had low to very-low-quality evidence. Thirty-one studies reported evidence relating to cost or resource use; data were insufficient to support generalisable conclusions. One hundred and six studies described implementation barriers and facilitators. Conclusions Management of childhood chronic functional constipation is complex. The available evidence remains limited, with small, poorly conducted and reported studies. Many evidence gaps were identified. Treatment recommendations within current clinical guidelines remain largely unchanged, but there is a need for research to move away from considering effectiveness of single interventions. Clinical care and future studies must consider the individual characteristics of children. Study registration This study is registered as PROSPERO CRD42019159008.

Functional response to a microbial synbiotic in the gastrointestinal system of children: a randomized clinical trial. Pediatr Res 2022:10.1038/s41390-022-02289-0. [PMID: 36319696 DOI: 10.1038/s41390-022-02289-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2022] [Revised: 07/23/2022] [Accepted: 07/29/2022] [Indexed: 03/05/2023]
Abstract
BACKGROUND Oral microbial therapy has been studied as an intervention for a range of gastrointestinal disorders. Though research suggests that microbial exposure may affect the gastrointestinal system, motility, and host immunity in a pediatric population, data have been inconsistent, with most prior studies being in neither a randomized nor placebo-controlled setting. The aim of this randomized, placebo-controlled study was to evaluate the efficacy of a synbiotic on increasing weekly bowel movements (WBMs) in constipated children. METHODS Sixty-four children (3-17 years of age) were randomized to receive a synbiotic (n = 33) comprising mixed-chain length oligosaccharides and nine microbial strains, or placebo (n = 31) for 84 days. Stool microbiota was analyzed on samples collected at baseline and completion. The primary outcome was a change from baseline of WBMs in the treatment group compared to placebo. RESULTS Treatment increased (p < 0.05) the number of WBMs in children with low baseline WBMs, despite broadly distinctive baseline microbiome signatures. Sequencing revealed that low baseline microbial richness in the treatment group significantly anticipated improvements in constipation (p = 0.00074). CONCLUSIONS These findings suggest the potential for (i) multi-species-synbiotic interventions to improve digestive health in a pediatric population and (ii) bioinformatics-based methods to predict response to microbial interventions in children. IMPACT Synbiotic microbial treatment improved the number of spontaneous weekly bowel movements in children compared to placebo. Intervention induced an increased abundance of bifidobacteria in children, compared to placebo. All administered probiotic species were enriched in the gut microbiome of the intervention group compared to placebo. Baseline microbial richness demonstrated potential as a predictive biomarker for response to intervention.

Efficacy, safety, and acceptability of polyethylene glycol 3350 without electrolytes vs magnesium hydroxide in functional constipation in children from six months to eighteen years of age: A controlled clinical trial. REVISTA DE GASTROENTEROLOGÍA DE MÉXICO (ENGLISH EDITION) 2021; 88:107-117. [PMID: 34961695 DOI: 10.1016/j.rgmxen.2021.12.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Accepted: 05/18/2021] [Indexed: 11/23/2022] Open
Abstract
INTRODUCTION AND AIMS There are few studies that compare polyethylene glycol (PEG) 3350 and magnesium hydroxide (MH), as long-term treatment of functional constipation (FC) in children, and they do not include infants as young as 6 months of age. Our aim was to determine the efficacy, safety, and acceptability of PEG vs MH in FC, in the long term, in pediatric patients. METHODS An open-label, parallel, controlled clinical trial was conducted on patients from 6 months to 18 years of age, diagnosed with FC, that were randomly assigned to receive PEG 3350 or MH for 12 months. Success was defined as: ≥ 3 bowel movements/week, with no fecal incontinence, fecal impaction, abdominal pain, or the need for another laxative. We compared adverse events and acceptability, measured as rejected doses of the laxative during the study, in each group and subgroup. RESULTS Eighty-three patients with FC were included. There were no differences in success between groups (40/41 PEG vs 40/42 MH, p = 0.616). There were no differences in acceptability between groups, but a statistically significant higher number of patients rejected MH in the subgroups > 4 to 12 years and > 12 to 18 years of age (P = .037 and P = .020, respectively). There were no differences regarding adverse events between the two groups and no severe clinical or biochemical adverse events were registered. CONCLUSIONS The two laxatives were equally effective and safe for treating FC in children from 0.5 to 18 years of age. Acceptance was better for PEG 3350 than for MH in patients above 4 years of age. MH can be considered first-line treatment for FC in children under 4 years of age.

Abstract
OBJECTIVES In the UK, Movicol paediatric plain (polyethylene glycol 3350 with electrolytes [PEG 3350+E], Norgine, UK), is licensed for chronic constipation in children 2 -11 years of age and faecal impaction (FI) from 5 years. This study aimed to investigate usage and characterise the risk profile in children under 2 years of age using PEG 3350+E in the UK. METHODS Retrospective, single exposure cohort study, with patients identified from Clinical Practice Research Datalink (CPRD) GOLD. Patients first prescribed PEG 3350+E under 2 years of age for the treatment of constipation or FI, between September 2003 and July 2019, were included. RESULTS There were 13,235 patients with a constipation indication and 40 patients with FI. For the constipation cohort: median age of PEG 3350+E first prescription was 1.2 years [interquartile range (IQR) 0.9, 1.6] and 68.4% had one treatment episode (TE). The mean duration of exposure, in the first TE, was 88.9 days. The most common total daily dose was one sachet (6.9 g).In terms of incident events on treatment, 0.5% of patients had abdominal pain, 3.0% had diarrhoea (may be attributed to treatment) and 4.1% had vomiting. 2.0% had signs/symptoms which could (in extreme cases) be associated with electrolyte disturbance, however, none had abnormal electrolyte values. DISCUSSION The safety aspect of this study did not identify any signals of concern in the constipation cohort. The number of patients in the FI cohort were too small for robust conclusions. If information were available, then a safety study would ideally assess treatment intake per kilogram, including electrolyte intake, before reaching safety conclusions. Nevertheless, these data contribute to real-world evidence on the use of PEG 3350+E in this population.

Abstract
Faecal disimpaction is very important for successful management of the constipation in children. Lactulose is cheap and widely available medicine compared to other polyethylene glycol (PEG) preparations. From our experience, lactulose is effective and safe medicine for both disimpaction and maintenance therapy in constipated children. The purpose of the present study was to evaluate the safety and efficacy of lactulose in faecal impaction management in children with constipation. We conducted a prospective controlled trial in children with functional constipation, who presented with faecal impaction to Queen Rania Hospital for Children from April 15, 2018 until October 15, 2018. Two randomised matched groups; group A included 33 constipated children treated for disimpaction with higher dose lactulose (10 g/15 ml) 4-6 ml/kg/day (max. 120 ml/day) and group B included 32 children treated for disimpaction with macrogol (PEG 4000) 1-1.5 g/kg (max. 30 g/day). Both groups received treatment until resolution or up to 6 days. Patients were followed over 1 week and success of disimpaction was observed. Moreover, any adverse events were recorded. All the patients in both groups achieved successful disimpaction by seventh day of the therapy, group B showed significant faster response. Both therapies were tolerated and no significant adverse events were reported. Both agents were safe, effective and well tolerated. Lactulose may be a good alternative to PEG in the treatment of faecal impaction in constipated children.

Macrogol 4000, a biologically inert, non-absorbable osmotic laxative, is a highly effective and well-tolerated first-line option for the treatment of the symptoms of chronic idiopathic/functional constipation in children and adults. High-molecular-weight (HMW) macrogols ± electrolytes have generally similar efficacy profiles; however, the taste of macrogol 4000 is generally preferred over that of macrogol 3350 + electrolytes. Macrogol 4000 is more effective than lactulose in improving stool frequency and consistency, and is associated with less vomiting and flatulence. Comparisons with other osmotic and bulk-forming laxatives are limited, with macrogol 4000 being at least as, or more effective than, psyllium hydrocolloid and magnesium hydroxide in treating chronic constipation. Current clinical treatment guidelines recommend the use of HMW macrogols over the use of lactulose and bulk-forming laxative in the symptomatic treatment of constipation in children and adults.

Abstract
OBJECTIVE The objective of this study was to evaluate in an analytical and descriptive manner the evidence published so far on the use of polyethylene glycol (PEG), with or without electrolytes, in the management of functional constipation and the treatment of fecal impaction. METHODOLOGY Search on MEDLINE, EMBASE and Cochrane databases until May 2016 of all publications adjusted to the following terms: constipation AND/OR fecal impaction AND (PEG OR polyethylene glycol OR macrogol OR movicol OR idralax OR miralax OR transipeg OR forlax OR golytely OR isocolan OR mulytely) NOT colonoscopy. Critical reading of selected articles (English or Spanish), sorting their description according to group age (adult/pediatric age) and within those, in accordance with study features (efficacy evaluation versus placebo, doses query, safety, comparison with other laxatives, observational studies and monographic review articles of polyethylene glycol or meta-analysis). RESULTS Fifty-eight publications have been chosen for descriptive analysis; of them, 41 are clinical trials, eight are observational studies and nine are systematic reviews or meta-analysis. Twelve clinical trials evaluate PEG efficacy versus placebo, eight versus lactulose, six are dose studies, five compare polyethylene glycol with and without electrolytes, two compare its efficacy with respect to milk of magnesia, and the rest of the trials evaluate polyethylene glycol with enemas (two), psyllium (one), tegaserod (one), prucalopride (one), paraffin oil (one), fiber combinations (one) and Descurainia sophia (one). CONCLUSIONS Polyethylene glycol with or without electrolytes is more efficacious than placebo for the treatment of functional constipation, either in adults or in pediatric patients, with great safety and tolerability. These preparations constitute the most efficacious osmotic laxatives (more than lactulose) and are the first-line treatment for functional constipation in the short and long-term. They are as efficacious as enemas in fecal impaction, avoid the need for hospital admission and are well tolerated by patients (mainly when administered without electrolytes).

Abstract
BACKGROUND AND OBJECTIVE Constipation is a common pediatric condition with a prevalence of 3% to 5% in children aged 4 to 17 years. Currently, there are no evidence-based guidelines for the management of pediatric patients hospitalized with constipation. The primary objective was to evaluate practice patterns and patient outcomes for the hospital management of functional constipation in US children's hospitals. METHODS We conducted a multicenter, retrospective cohort study of children aged 0 to 18 years hospitalized for functional constipation from 2012 to 2014 by using the Pediatric Health Information System. Patients were included by using constipation and other related diagnoses as classified by International Classification of Diseases, Ninth Revision. Patients with complex chronic conditions were excluded. Outcome measures included percentage of hospitalizations due to functional constipation, therapies used, length of stay, and 90-day readmission rates. Statistical analysis included means with 95% confidence intervals for individual hospital outcomes. RESULTS A total of 14 243 hospitalizations were included, representing 12 804 unique patients. The overall percentage of hospitalizations due to functional constipation was 0.65% (range: 0.19%-1.41%, P < .0001). The percentage of patients receiving the following treatment during their hospitalization included: electrolyte laxatives: 40% to 96%; sodium phosphate enema: 0% to 64%; mineral oil enema: 0% to 61%; glycerin suppository: 0% to 37%; bisacodyl 0% to 47%; senna: 0% to 23%; and docusate 0% to 11%. Mean length of stay was 1.97 days (range: 1.31-2.73 days, P < .0001). Mean 90-day readmission rate was 3.78% (range: 0.95%-7.53%, P < .0001). CONCLUSIONS There is significant variation in practice patterns and clinical outcomes for pediatric patients hospitalized with functional constipation across US children's hospitals. Collaborative initiatives to adopt evidence-based best practices guidelines could help standardize the hospital management of pediatric functional constipation.

Abstract
This review intends to update what is known about and what is still a challenge in functional constipation (FC) in children regarding epidemiology, pathophysiology, diagnosis, and management. Although FC is a common childhood problem, its global burden remains unknown as data from parts of the world are missing. Another problem is that there is a large variation in prevalence due to differences in study methods and defining age groups. The pathophysiology of FC remains unclear to date but is probably multifactorial. Withholding behavior is likely to be the most important factor in toddlers and young children. Genetics may also play a role since many patients have positive family history, but mutations in genes associated with FC have not been found. Over the past years, different diagnostic criteria for FC in infants and children have been proposed. This year, Rome IV criteria have been released. Compared to Rome III, it eliminates two diagnostic criteria in children under the age of 4 who still wear diapers. Physical examination and taking a thorough medical history are recommended, but other investigations such as abdominal radiography, transabdominal recto-ultrasonography, colonic transit time, rectal biopsies, and colon manometry are not routinely recommended. Regarding treatment, guidelines recommend disimpaction and maintenance therapy with polyethylene glycol (PEG) with or without electrolytes. But experience shows that acceptability, adherence, and tolerance to PEG are still a challenge. Counseling of parents and children about causes of FC is often neglected. Recent studies suggest that behavior therapy added to laxative therapy improves the relief of symptoms. Further homogeneous studies, better-defined outcomes, and studies conducted in primary care are needed.

Abstract
BACKGROUND Constipation within childhood is an extremely common problem. Despite the widespread use of osmotic and stimulant laxatives by health professionals to manage constipation in children, there has been a long standing paucity of high quality evidence to support this practice. OBJECTIVES We set out to evaluate the efficacy and safety of osmotic and stimulant laxatives used to treat functional childhood constipation. SEARCH METHODS We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, and the Cochrane IBD Group Specialized Trials Register from inception to 10 March 2016. There were no language restrictions. We also searched the references of all included studies, personal contacts and drug companies to identify studies. SELECTION CRITERIA Randomised controlled trials (RCTs) which compared osmotic or stimulant laxatives to placebo or another intervention, with participants aged 0 to 18 years old were considered for inclusion. The primary outcome was frequency of defecation. Secondary endpoints included faecal incontinence, disimpaction, need for additional therapies and adverse events. DATA COLLECTION AND ANALYSIS Relevant papers were identified and two authors independently assessed the eligibility of trials, extracted data and assessed methodological quality using the Cochrane risk of bias tool. The primary outcome was frequency of defecation. Secondary endpoints included faecal incontinence, disimpaction, need for additional therapies and adverse events. For continuous outcomes we calculated the mean difference (MD) and 95% confidence interval (CI) using a fixed-effect model. For dichotomous outcomes we calculated the risk ratio (RR) and 95% CI using a fixed-effect model. The Chi(2) and I(2) statistics were used to assess statistical heterogeneity. A random-effects model was used in situations of unexplained heterogeneity. We assessed the overall quality of the evidence supporting the primary and secondary outcomes using the GRADE criteria. MAIN RESULTS Twenty-five RCTs (2310 participants) were included in the review. Fourteen studies were judged to be at high risk of bias due to lack of blinding, incomplete outcome data and selective reporting. Meta-analysis of two studies (101 patients) comparing polyethylene glycol (PEG) with placebo showed a significantly increased number of stools per week with PEG (MD 2.61 stools per week, 95% CI 1.15 to 4.08). Common adverse events in the placebo-controlled studies included flatulence, abdominal pain, nausea, diarrhoea and headache. Participants receiving high dose PEG (0.7 g/kg) had significantly more stools per week than low dose PEG (0.3 g/kg) participants (1 study, 90 participants, MD 1.30, 95% 0.76 to 1.84). Meta-analysis of 6 studies with 465 participants comparing PEG with lactulose showed a significantly greater number of stools per week with PEG (MD 0.70 , 95% CI 0.10 to 1.31), although follow-up was short. Patients who received PEG were significantly less likely to require additional laxative therapies. Eighteen per cent (27/154) of PEG patients required additional therapies compared to 31% (47/150) of lactulose patients (RR 0.55, 95% CI 0.36 to 0.83). No serious adverse events were reported with either agent. Common adverse events in these studies included diarrhoea, abdominal pain, nausea, vomiting and pruritis ani. Meta-analysis of 3 studies with 211 participants comparing PEG with milk of magnesia showed that the stools per week were significantly greater with PEG (MD 0.69, 95% CI 0.48 to 0.89). However, the magnitude of this difference was quite small and may not be clinically significant. One child was noted to be allergic to PEG, but there were no other serious adverse events reported. One study found a significant difference in stools per week favouring milk of magnesia over lactulose (MD -1.51, 95% CI -2.63 to -0.39, 50 patients), Meta-analysis of 2 studies with 287 patients comparing liquid paraffin (mineral oil) with lactulose revealed a relatively large statistically significant difference in the number of stools per week favouring liquid paraffin (MD 4.94 , 95% CI 4.28 to 5.61). No serious adverse events were reported. Adverse events included abdominal pain, distention and watery stools. No statistically significant differences in the number of stools per week were found between PEG and enemas (1 study, 90 patients, MD 1.00, 95% CI -1.58 to 3.58), dietary fibre mix and lactulose (1 study, 125 patients, P = 0.481), senna and lactulose (1 study, 21 patients, P > 0.05), lactitol and lactulose (1 study, 51 patients, MD -0.80, 95% CI -2.63 to 1.03), hydrolyzed guar gum and lactulose (1 study, 61 patients, MD 1.00, 95% CI -1.80 to 3.80), PEG and flixweed (1 study, 109 patients, MD 0.00, 95% CI -0.33 to 0.33), PEG and dietary fibre (1 study, 83 patients, MD 0.20, 95% CI -0.64 to 1.04), and PEG and liquid paraffin (2 studies, 261 patients, MD 0.35, 95% CI -0.24 to 0.95). AUTHORS' CONCLUSIONS The pooled analyses suggest that PEG preparations may be superior to placebo, lactulose and milk of magnesia for childhood constipation. GRADE analyses indicated that the overall quality of the evidence for the primary outcome (number of stools per week) was low or very low due to sparse data, inconsistency (heterogeneity), and high risk of bias in the studies in the pooled analyses. Thus, the results of the pooled analyses should be interpreted with caution because of quality and methodological concerns, as well as clinical heterogeneity, and short follow-up. There is also evidence suggesting the efficacy of liquid paraffin (mineral oil). There is no evidence to demonstrate the superiority of lactulose when compared to the other agents studied, although there is a lack of placebo controlled studies. Further research is needed to investigate the long term use of PEG for childhood constipation, as well as the role of liquid paraffin. The optimal dose of PEG also warrants further investigation.

Abstract
AIM Constipation is a common cause of admission to hospital for disimpaction, as oral laxatives are often inadequate. High-dose oral laxative protocols are used for complete bowel clearance prior to colonoscopy, but have not been reported for treating faecal impaction. The aim of this study was to assess the effectiveness of a high-dose oral protocol using polyethylene glycol with electrolytes (PEG + E) (Movicol Rx) combined with sodium picosulphate (SP) (Dulcolax SP Rx) in faecal impaction in children presenting to a suburban clinic. METHODS Forty-four children presented with acute/chronic faecal impaction were given six to eight sachets of PEG + E were given on day 1, with decreasing doses on subsequent 3 days, while 15-20 SP drops were given on days 2 and 3. Compliance with medication was achieved using a simple method of motivation, with the child drinking the laxatives in a race. On day 4, PEG + E was reduced to one sachet and SP to 10 drops as an ongoing maintenance dose. Defecation, soiling, diet and water intake was monitored daily for 7 days in a diary. RESULTS Forty-four children (aged 2-17 years) seen over 8 months were reviewed retrospectively. Children began defecating within 10-12 h reaching a maximum volume of stool/day (four cups) on day 2. All patients were disimpacted successfully and in the week following disimpaction there was no reported faecal soiling or complications. CONCLUSIONS A high-dose oral protocol combining PEG + E sachets and SP drops successfully and safely disimpacted a cohort of children with acute/chronic constipation presenting to a suburban continence clinic. This protocol appears to be useful to control faecal disimpaction in an outpatient setting, thereby avoiding hospital admission.

Abstract
Background: Polyethylene glycol (PEG) is often considered as the first-line treatment for functional constipation in children. Descurainia sophia (L.) Webb et Berth (D. sophia) is a safe recommended medicine in Iranian folk and Traditional Persian Medicine for the treatment of constipation. Objectives: To clinically compare D. sophia with PEG 4000 (without electrolyte) in pediatric constipation and to assess its efficacy and side effects. Patients and Methods: 120 patients aged 2 - 12 years with constipation for at least 3 months were included in an 8 weeks lasting randomized controlled trial within two parallel-groups. Children received either PEG, 0.4 g/kg/day, or D. sophia seeds, 2 grams (for children aged 2 - 4 years) and 3 grams (for those aged > 4 years) per day. Results: A total of 109 patients completed the study (56 in D. sophia and 53 in PEG group). At the end of the study, 36 (64.3%) patients in D. sophia group and 29 (54.7%) in PEG group were out of Rome III criteria (P = 0.205). Median weekly stool frequency in 0, 1, 2, 3 weeks of the treatment was found to be 2, 5, 5, 5 in D. sophia and 3, 4, 4, 5 in PEG group (P = 0.139, 0.076, 0.844, 0.294), respectively. The number of patients who suffered flatulence was less (5, 8.9%) in D. sophia group as compared to PEG group (6, 11.3%) at the end of the trial (P = 0.461). D. sophia taste was less tolerated. Conclusions: D. sophia is introduced as a cheap and available medication which can be applied as a safe alternative to conventional PEG in the management of pediatric chronic functional constipation.

Abstract
BACKGROUND Constipation is an uncomfortable and common condition that affects many, irrespective of age. Since 1500 BC and before, health care practitioners have provided treatments and prevention strategies to patients for chronic constipation despite the significant variation in both medical and personal perceptions of the condition. OBJECTIVE To review relevant research evidence from clinical studies investigating the efficacy and safety of commercially available pharmacological laxatives in Canada, with emphasis on studies adopting the Rome criteria for defining functional constipation. SEARCH METHODS PubMed, Medline, Embase and Evidence-Based Medicine Reviews databases were searched for blinded or randomized clinical trials and meta-analyses assessing the efficacy of nonstimulant and stimulant laxatives for the treatment of functional constipation. RESULTS A total of 19 clinical studies and four meta-analyses were retrieved and abstracted regarding study design, participants, interventions and outcomes. The majority of studies focused on polyethylene glycol compared with placebo. Both nonstimulant and stimulant laxatives provided better relief of constipation symptoms than placebo according to both objective and subjective measures. Only one study compared the efficacy of a nonstimulant versus a stimulant laxative, while only two reported changes in quality of life. All studies reported minor side effects due to laxative use, regardless of treatment duration, which ranged from one week to one year. Laxatives were well tolerated by both adults and children.
