The frequency of constipation in children with nocturnal enuresis: a comparison with parental reporting

Constipation: A Pristine Universal Pediatric Health Delinquent

Constipation suffered by children is a global public health problem. Functional constipation (FC) brings about deteriorating effects in the children's lives who suffer from it. The risk factors for the development of constipation include the consumption of a diet low in fiber and high in calories (such as the consumption of fast food), a sedentary lifestyle with a lack of exercise, a family history of constipation, and emotional and psychological stress endured by children in their families. It is one of the most common causes of stomachaches in children. FC may lead to fecal incontinence (FI), anal fissures, recurrent urinary tract infections (RUTI), and enuresis in children. Severe constipation may result in stool becoming rock-hard and inflexible in the rectum, which is clinically identified as fecal impaction. It is imperative to perform clinical evaluation and treatment, including pharmacological (the use of stimulant and osmotic laxatives) and non-pharmacological (education, changes in diet, intervention to promote positive behavior and address any emotional issues, toilet training, and physiotherapy for the pelvic floor) interventions. In the case of refractory patients, neuromodulation, the irrigation of the anal canal, and surgical management may be needed. It is essential to lead a healthy, stress-free lifestyle with plenty of exercise and a balanced diet rich in fiber (such as fruits and vegetables) so children can have regular bowel habits and thrive.

A Scoping Review of Non-Pharmacological Health Education Provided to Families of Children With Idiopathic Childhood Constipation Within Primary Health Care

Objectives:

Idiopathic childhood constipation is a prevalent condition that initially brings the child under the care of the primary health care team. Although it is acknowledged that health education is crucial to reducing chronicity, the range of evidenced-based non-pharmacological health education provided to families has not previously been reviewed. For this scoping review, 4 research questions sought to identify papers that provide information on the utilization of guidelines, the range of health education, who provides it, and whether any gaps exist.

Methods:

Following a registered protocol and using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews, searches of 10 online databases, reference lists, Google Scholar, and book chapter references were made. Eligible papers were original research published in English between January 2000 and December 2022.

Results:

Twelve worldwide studies (2 qualitative and 10 quantitative) reported that: evidence-based guidelines are not consistently used by primary care providers; the range of non-pharmacological health education provided is inconsistent; the non-pharmacological health education is provided by doctors, nurses, and pharmacists; and that gaps exist in non-pharmacological health education provision.

Conclusion:

This review demonstrates that rather than a lack of guideline-awareness, decreased specific idiopathic childhood constipation knowledge (and possibly time) may be responsible for inconsistent non-pharmacological health education. Inappropriate treatment and management of some children escalates risk for chronicity. Improving health education provision however, may be achieved through: increased collaboration; better utilization of nurses; and through developing the child’s health literacy by involving both child and family in all aspects of health education and decision-making.

Alarm interventions for nocturnal enuresis in children

BACKGROUND

Enuresis (bedwetting) affects up to 20% of five-year-olds and can have considerable social, emotional and psychological effects. Treatments include alarms (activated by urination), behavioural interventions and drugs.

OBJECTIVES

To assess the effects of enuresis alarms for treating enuresis in children.

SEARCH METHODS

We searched the Cochrane Incontinence Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, ClinicalTrials.gov, WHO ICTRP, and handsearching of journals and conference proceedings (searched 25 June 2018), and reference lists of relevant articles.

SELECTION CRITERIA

We included randomised or quasi-randomised trials of enuresis alarms or alarms combined with another intervention for treating nocturnal enuresis in children between 5 and 16 years old.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed risk of bias and extracted data.

MAIN RESULTS

We included 74 trials (5983 children). At treatment completion, alarms may reduce the number of wet nights a week compared to control or no treatment (mean difference (MD) -2.68, 95% confidence interval (CI) -4.59 to -0.78; 4 trials, 127 children; low-quality evidence). Low-quality evidence suggests more children may achieve complete response (14 consecutive dry nights) with alarms compared to control or no treatment (RR 7.23, 95% CI 1.40 to 37.33; 18 trials, 827 children) and that more children may remain dry post-treatment (RR 9.67, 95% CI 4.74 to 19.76; 10 trials, 366 children; low-quality evidence). At treatment completion, we are uncertain whether there is any difference between alarms and placebo drugs in the number of wet nights a week (MD -0.96, 95% CI -2.32 to 0.41; 1 trial, 47 children; very low-quality evidence). Alarms may result in more children achieving complete response than with placebo drugs (RR 1.59, 95% CI 1.16 to 2.17; 2 trials, 181 children; low-quality evidence). No trials comparing alarms to placebo reported the number of children remaining dry post-treatment. Compared with control alarms, code-word alarms probably slightly increase the number of children achieving complete response at treatment completion (RR 1.11, 95% CI 0.97 to 1.27; 1 trial, 353 children; moderate-quality evidence) but there is probably little to no difference in the number of children remaining dry post-treatment (RR 0.91, 95% CI 0.79 to 1.05; moderate-quality evidence). Very low-quality evidence means we are uncertain if there are any differences in effectiveness between the other different types of alarm. At treatment completion, alarms may reduce the number of wet nights a week compared with behavioural interventions (waking, bladder training, dry-bed training, and star chart plus rewards) (MD -0.81, 95% CI -2.01 to 0.38; low-quality evidence) and may increase the number of children achieving complete response (RR 1.77, 95% CI 0.98 to 3.19; low-quality evidence) and may slightly increase the number of children remaining dry post-treatment (RR 1.39, 95% CI 0.81 to 2.41; low-quality evidence). The evidence relating to alarms compared with desmopressin in the number of wet nights a week (MD -0.64, 95% CI -1.77 to 0.49; 4 trials, 285 children) and the number of children achieving complete response at treatment completion (RR 1.12, 95% CI 0.93 to 1.36; 12 trials, 1168 children) is low-quality, spanning possible harms and possible benefits. Alarms probably slightly increase the number of children remaining dry post-treatment compared with desmopressin (RR 1.30, 95% CI 0.92 to 1.84; 5 trials, 565 children; moderate-quality evidence). At treatment completion, we are uncertain if there is any difference between alarms and tricyclics in the number of wet nights a week, the number of children achieving complete response or the number of children remaining dry post-treatment, because the quality of evidence is very low. Due to very low-quality evidence we are uncertain about any differences in effectiveness between alarms and cognitive behavioural therapy, psychotherapy, hypnotherapy and restricted diet. Alarm plus desmopressin may reduce the number of wet nights a week compared with desmopressin monotherapy (MD -0.88, 95% CI -0.38 to -1.38; 2 trials, 156 children; low-quality evidence). Alarm plus desmopressin may increase the number of children achieving complete response (RR 1.32, 95% CI 1.08 to 1.62; 5 trials, 359 children; low-quality evidence) and the number of children remaining dry post-treatment (RR 2.33, 95% CI 1.26 to 4.29; 2 trials, 161 children; low-quality evidence) compared with desmopressin alone. Alarm plus dry-bed training may increase the number of children achieving a complete response compared to dry-bed training alone (RR 3.79, 95% CI 1.85 to 7.77; 1 trial, 80 children; low-quality evidence). It is unclear if there is any difference in the number of children remaining dry post-treatment because of the wide confidence interval (RR 0.56, 95% CI 0.15 to 2.12; low-quality evidence). Due to very low-quality evidence, we are uncertain about any differences in effectiveness between alarm plus bladder training versus bladder training alone. Of the 74 included trials, 17 reported one or more adverse events, nine reported no adverse events and 48 did not mention adverse events. Adverse events attributed to alarms included failure to wake the child, ringing without urination, waking others, causing discomfort, frightening the child and being too difficult to use. Adverse events of comparator interventions included nose bleeds, headaches and abdominal pain. There is probably a slight increase in adverse events between code-word alarm and standard alarm (RR 1.34, 95% CI 0.75 to 2.38; moderate-quality evidence), although we are uncertain because of the wide confidence interval. Alarms probably reduce the number of children experiencing adverse events compared with desmopressin (RR 0.38, 95% CI 0.20 to 0.71; 5 trials, 565 children; moderate-quality evidence). Very low-quality evidence means we cannot be certain whether the adverse event rate for alarms is lower than for other treatments.

AUTHORS' CONCLUSIONS

Alarm therapy may be more effective than no treatment in reducing enuresis in children. We are uncertain if alarm therapy is more effective than desmopressin but there is probably a lower risk of adverse events with alarms than with desmopressin. Despite the large number of trials included in this review, further adequately-powered trials with robust randomisation are still needed to determine the full effect of alarm therapy.

Association between constipation and childhood nocturnal enuresis in Taiwan: a population-based matched case-control study

BACKGROUND

The relationship between constipation and childhood nocturnal enuresis (NE) has been previously reported; however, this relationship remains controversial. The present study aimed to evaluate the association between constipation and childhood NE.

METHODS

Data from the Longitudinal Health Insurance Database 2000 (LHID 2000) of Taiwan National Health Insurance Research Database from 2000 to 2013 were collected. A total of 2286 children were enrolled in this study: a case group of 1143 children aged 5-18 years who were diagnosed with NE (NE group) and an age- and sex-matched control group of 1143 children without NE. Conditional logistic regression and odds ratio (OR) for NE were used to examine the association between constipation and childhood NE.

RESULTS

The prevalence of NE in the case group (NE group, aged 5-18 years) was 1.03% from 2000 to 2013. The NE group had a higher percentage of constipation in 1 year before the diagnosis of NE. After stratification for sex, both boys and girls with constipation had higher OR for NE. With stratification for age, children aged 5-12 and 7-12 years had a higher OR for NE.

CONCLUSIONS

Constipation is associated with childhood NE in Taiwan, particularly in children aged 5-7 and 7-12 years.

Traditional Biofeedback vs. Pelvic Floor Physical Therapy-Is One Clearly Superior?

PURPOSE OF REVIEW

Pelvic floor physical therapy is a worldwide accepted therapy that has been exclusively used to manage many pelvic floor disorders in adults and children. The aim of this review is to suggest to clinicians an updated understanding of this therapeutic approach in management of children with non-neuropathic voiding dysfunction.

RECENT FINDINGS

Today, pelvic floor muscle training through biofeedback is widely used as a part of a voiding retraining program aiming to help children with voiding dysfunction which is caused by pelvic floor overactivity. Biofeedback on its own, without a pelvic floor training component, is not an effective treatment. Biofeedback is an adjunct to the pelvic floor training. In the current review, we develop the role of pelvic floor physical therapy in management of children with non-neuropathic voiding dysfunction and compare it with biofeedback therapy alone.

Rectal diameter assessment in enuretic children-exploring the association between constipation and bladder function

OBJECTIVES

Detrusor overactivity and constipation often co-exist in children with enuresis. Constipation is known to be linked to detrusor overactivity. The voiding chart is the best non-invasive way to investigate bladder function, whereas the ultrasonographical detection of rectal dilatation is the best way to objectify constipation. We wanted to investigate a possible relationship between the rectal diameter and voiding chart data in enuretic children.

METHODS

Children with therapy-resistant enuresis were retrospectively evaluated. All had completed a voiding chart for at least 48 h. The rectal diameter was assessed ultrasonographically. The cutoff for rectal dilatation was set at 30 mm.

RESULTS

We evaluated 74 patients (12 girls) aged 10.2 ± 2.8 years, 35 of whom had rectal dilatation. No significant differences in voiding chart parameters were found between children with normal versus dilated rectum. Neither did urgency or a history of daytime incontinence differ between the groups. Boys were more likely to have rectal dilatation than girls (p = 0.02).

CONCLUSIONS

The absence of differences regarding voiding chart data may be explained as two mechanisms neutralizing each other: behavioral factors may make the constipated children void seldom and with large volumes, whereas detrusor overactivity caused by rectal compression of the bladder may have the opposite effect. Another option may be that the voiding chart is too blunt an instrument to detect detrusor overactivity. Constipation, and thus presumably bladder dysfunction, seems to be more important in enuretic boys than girls.

Time Course of Treatment for Primary Enuresis With Overactive Bladder

PURPOSE

To characterize the course of treatment for nonmonosymptomatic enuresis with overactive bladder (OAB) in a real clinical setting.

METHODS

Data from 111 OAB patients with moderate to severe enuresis were analyzed. The baseline analysis included a questionnaire, voiding diary, uroflowmetry with postvoid residual urine measurement, and plain abdominal radiography of the kidneys, ureters, and bladder (KUB). Following standard urotherapy for 1 month, anticholinergic medication was administered with or without laxatives. Desmopressin was added if there was a partial response to OAB. Patients were followed every 3 months to evaluate the status of OAB and enuresis. Multivariate analysis was performed to identify predictors associated with the lack of complete response (CR) in enuresis at 12 months.

RESULTS

Following 12 months of treatment, 64% and 88% of patients experienced at least partial response in enuresis and OAB, respectively. Urgency improved more quickly than enuresis, supporting the need to address daytime symptoms before enuresis. Seventy-nine patients (71%) had fecal impaction on KUB and/or subjective constipation. The combination of anticholinergics with either laxatives or desmopressin fared better than anticholinergics alone. Daytime incontinence and anticholinergics- only treatment were associated with a lack of CR during 12 months of treatment.

Conclusions

The data confirmed the validity of addressing OAB before treating enuresis. The results of this study also highlight the need to address fecal impaction. Patients should be counseled about the need for a prolonged course of treatment before starting treatment. Anticholinergics should be accompanied with either desmopressin or laxatives for better control of enuresis.

Bladder and bowel dysfunctions in 1748 children referred to pelvic physiotherapy: clinical characteristics and locomotor problems in primary, secondary, and tertiary healthcare settings

The aims of this study are to evaluate in a pragmatic cross-sectional study, the clinical characteristics of childhood bladder and/or bowel dysfunctions (CBBD) and locomotor problems in the primary through tertiary health care setting. It was hypothesized that problems would increase, going from primary to tertiary healthcare. Data were retrieved from patient-records of children (1-16 years) presenting with CBBD and visiting pelvic physiotherapists. Prevalence's of dysfunctions were compared between healthcare settings and gender using ANOVA and chi-square test. Agreement between physicians' diagnoses and parent-reported symptoms was evaluated (Cohen's Kappa). One thousand seventy hundred forty-eight children (mean age 7.7 years [SD 2.9], 48.9% boys) were included. Daytime urinary incontinence (P = 0.039) and enuresis (P < 0.001) were more diagnosed in primary healthcare, whereas constipation (P < 0.001) and abdominal pain (P = 0.009) increased from primary to tertiary healthcare. All parent-reported symptoms occurred more frequently than indicated by the physicians. Poor agreement between physicians' diagnoses and parent-reported symptoms was found (k = 0.16). Locomotor problems prevailed in all healthcare settings, motor skills (P = 0.041) and core stability (P = 0.015) significantly more in tertiary healthcare.

CONCLUSIONS

Constipation and abdominal pain (physicians' diagnoses) and the parent-reported symptoms hard stools and bloating increased from primary to tertiary healthcare. Discrepancies exist between the prevalence's of physicians' diagnoses and parent-reported symptoms. Locomotor problems predominate in all healthcare settings. What is Known: • Childhood bladder and/or bowel dysfunctions (CCBD) are common. • Particularly tertiary healthcare characteristics of CBBD are available What is New: • Characteristics of CBBD referred to pelvic physiotherapy are comparable in primary, secondary, and tertiary healthcare settings. • Concomitant CBBD appeared to be more prevalent than earlier reported. • Discrepancies exist between referring physicians' diagnoses and parent-reported symptoms.

Tricyclic and related drugs for nocturnal enuresis in children

BACKGROUND

Enuresis (bedwetting) affects up to 20% of five year-olds and 2% of adults. Although spontaneous remission often occurs, the social, emotional and psychological costs can be great. Tricyclics have been used to treat enuresis since the 1960s.

OBJECTIVES

To assess the effects of tricyclic and related drugs compared with other interventions for treating children with enuresis.

SEARCH METHODS

We searched the Cochrane Incontinence Group Specialised Trials Register (containing trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE in process, ClinicalTrials.gov, WHO ICTRP and handsearching of journals and conference proceedings), on 30 November 2015, and reference lists of relevant articles.

SELECTION CRITERIA

We included all randomised and quasi-randomised trials comparing a tricyclic or related drug with another intervention for treating enuresis. We also included combination therapies that included tricyclics. We excluded trials for treating daytime wetting.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed the quality of the eligible trials, and extracted data. We settled differences by discussion with a third review author.

MAIN RESULTS

Sixty-four trials met the inclusion criteria, involving 4071 children. The quality of many trials was poor, with comparisons addressed by single studies. Minor adverse effects were common, and reported in 30 trials. These included dizziness, headache, mood changes, gastrointestinal discomforts and neutropenia. More serious side-effects can occur but were not reported. Seven trials reported no adverse effects.Tricyclics are more effective than placebo, particularly for short-term outcomes. Compared to placebo, imipramine resulted in one fewer wet nights per week (mean difference (MD) -0.95, 95% confidence interval (CI) -1.40 to -0.50; 4 trials, 347 children), with fewer failing to achieve 14 consecutive dry nights (78% versus 95% for placebo, RR 0.74, 95% CI 0.61 to 0.90; 12 trials, 831 children). Amitriptyline and desipramine were more effective than placebo, but nortriptyline and mianserin showed no difference. Most tricyclics did not have a sustained effect after ceasing treatment, with 96% wetting at follow-up for imipramine versus 97% for placebo.Imipramine combined with oxybutynin is also more effective than placebo, with 33% failing to achieve 14 consecutive dry nights at the end of treatment versus 78% for placebo (RR 0.43, 95% CI 0.23 to 0.78; 1 trial, 47 children) and 45% wetting at follow-up versus 79% for placebo (RR 0.58, 95% CI 0.34 to 0.99; 1 trial, 36 children).There was insufficient evidence to judge the effect between different doses of tricyclics, and between different tricyclics. Treatment outcomes between tricyclic and desmopressin were similar, but were mixed when tricyclic was compared with an anticholinergic. However, when imipramine was compared with desmopressin plus oxybutynin (1 trial, 45 children), the combination therapy was more effective, with one fewer wet nights per week (MD 1.07, 95% CI 0.06 to 2.08) and 36% failing to achieve 14 consecutive dry nights versus 87% for imipramine (RR 2.39, 95% CI 1.35 to 4.25). Tricyclics were also more effective or showed no difference in response when compared to other drugs which are no longer used for enuresis.Tricyclics were less effective than alarms. Although there was no difference in the number of wet nights, 67% failed to achieve 14 consecutive dry nights for imipramine versus only 17% for alarms (RR 4.00, 95% CI 1.06 to 15.08; 1 trial, 24 children). Alarm therapy also had a more sustained effect after ceasing treatment with 100% on imipramine versus 58% on alarms wetting at follow-up (RR 1.67, 95% CI 1.03 to 2.69; 1 trial, 24 children).Imipramine was more effective than simple behavioural therapies during treatment, with one fewer wet nights per week compared with star chart plus placebo (MD -0.80, 95% CI -1.33 to -0.27; 1 trial, 250 children). At follow-up 40% were wet with imipramine versus 80% with fluids and avoiding punishment (RR 0.50, 95% CI 0.28 to 0.89; 1 trial, 40 children). However, imipramine was less effective than complex behavioural therapies, with 61% failing to achieve 14 consecutive dry nights for imipramine versus 33% for the three-step programme (RR 1.83, 95% CI 1.08 to 3.12; 1 trial, 72 children) and 16% for the three-step programme combined with motivational therapy and computer-led education (RR 3.91, 95% CI 2.30 to 6.66; 1 trial, 132 children) at the end of treatment, with similar results at follow-up.Tricyclics were more effective than restricted diet, with 99% failing to achieve 14 consecutive dry nights versus 84% for imipramine (RR 0.84, 95% CI 0.75 to 0.93; 1 trial, 147 children).There was insufficient evidence to judge the effect of tricyclics compared to the other miscellaneous interventions studied.At the end of treatment there were about two fewer wet nights for imipramine plus oxybutynin compared with imipramine monotherapy (MD -2.10, 95% CI -2.99 to -1.21; 1 trial, 63 children) and 48% on imipramine plus oxybutynin failed to achieve 14 consecutive dry nights compared with 74% on imipramine monotherapy (RR 0.68, 95% CI 0.50 to 0.92; 2 trials, 101 children). At follow-up, 45% on imipramine plus oxybutynin were wetting versus 83% on imipramine monotherapy (RR 0.55, 95% CI 0.32 to 0.92; 1 trial, 36 children).When imipramine combined with desmopressin was compared with imipramine monotherapy, there was no difference in outcomes. However, when imipramine plus desmopressin was compared with desmopressin monotherapy, the combination was more effective, with 15% not achieving 14 consecutive dry nights at the end of treatment for imipramine plus desmopressin versus 40% for desmopressin monotherapy (RR 0.38, 95% CI 0.17 to 0.83; 1 trial, 86 children). Tricyclics combined with alarm therapy were not more effective than alarm monotherapy, alarm combined with desmopressin or alarm combined with nortriptyline. The addition of a tricyclic to other behavioural therapies did not alter treatment response.

AUTHORS' CONCLUSIONS

There was evidence that tricyclics are effective at reducing the number of wet nights during treatment, but do not have a sustained effect after treatment stops, with most children relapsing. In contrast, there was evidence that alarm therapy has better short- and long-term outcomes. There was some evidence that tricyclics combined with anticholinergics may be more effective that tricyclic monotherapy.

Urinary incontinence in children

BACKGROUND

Urinary incontinence (bedwetting, enuresis) is the commonest urinary symptom in children and adolescents and can lead to major distress for the affected children and their parents. Physiological and non-physiological types of urinary incontinence are sometimes hard to tell apart in this age group.

METHODS

This article is based on selected literature retrieved by a PubMed search and on an interdisciplinary expert consensus.

RESULTS AND CONCLUSION

Nocturnal enuresis has a variety of causes. The main causative factors in monosymptomatic enuresis nocturna (MEN) are an impaired ability to wake up when the bladder is full, due to impaired or absent perception of fullness during sleep, and an imbalance between bladder capacity and nocturnal urine production. On the other hand, non-monosymptomatic enuresis nocturna (non-MEN) is usually traceable to bladder dysfunction, which is also the main cause of diurnal incontinence. A basic battery of non-invasive diagnostic tests usually suffices to determine which type of incontinence is present. Further and more specific testing is indicated if an organic cause is suspected or if the treatment fails. The mainstay of treatment is urotherapy (all non-surgical and non-pharmacological therapeutic modalities). Some patients, however, will need supportive medication in addition. Urinary incontinence has different causes in children and adults and must therefore be diagnosed and treated differently as well. All physicians who treat the affected children (not just pediatricians and family doctors, but also pediatric nephrologists, urologists, pediatric surgeons, and child psychiatrists) must be aware of the specific features of urinary incontinence in childhood.
