Treatment of primary nocturnal enuresis in children: a review

Age-Dependent Responsiveness to Smoke Alarm Signals Among Children

OBJECTIVES

Although it has been established that smoke alarms have more difficulty awakening children from sleep than adults, no attempt has been previously made to characterize how smoke alarm responsiveness changes with age during childhood. The objective of this study is to evaluate the age-dependent responsiveness to various smoke alarm signals among children 5 to 12 years old.

METHODS

The effect of age on children's response to 4 types of smoke alarms (human voice, hybrid voice-tone, low-frequency tone, and high-frequency tone) was evaluated using combined data from 3 previous studies.

RESULTS

There were 540 subjects (median age 9 years; 51.7% male). The proportion of children who awakened demonstrated a statistically significant (P < .001) increase of 3.1% to 7.6% for each additional year of age between 5 and 12 years old for the 4 alarm types. Similarly, child age showed a statistically significant (P < .001) effect on the proportion who escaped for each of the 4 alarm types. The proportion of subjects who awakened or escaped did not differ significantly by sex for any of the alarm types. Median time-to-awaken and median time-to-escape decreased with increase in child age for all alarm types.

CONCLUSIONS

This study demonstrates the substantial influence of child age on the effectiveness of audible smoke alarms during childhood. Among 12-year-olds, only 56.3% escaped within 1 minute (and 67.6% within 2 minutes) to a high-frequency tone. However, a hybrid voice-low-frequency tone alarm is >96% effective at awakening and prompting escape within 1 minute among children 9 years and older.

Psychiatric comorbidities of children with elimination disorders

Enuresis and encopresis can be stressful for children and parents. We investigated the comorbid psychiatric disorders and the emotional and behavioral symptoms associated with elimination disorders. A total of 97 children and adolescents (aged 4-17 years) with an elimination disorder participated in this study. The elimination disorder group consisted of three subgroups: 50 subjects with enuresis nocturna, 26 with encopresis, and 21 subjects with enuresis+encopresis. The control group with no elimination disorder comprised 50 healthy subjects. All children were interviewed by a child and adolescent psychiatrist. Comorbid psychiatric disorders were assessed using the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime version (K-SADS-PL). Parents completed the Strengths and Difficulties Questionnaire. The most common diagnosis was attention-deficit/hyperactivity disorder, followed by oppositional defiant disorder. The highest rate of psychiatric comorbidity was observed in the enuresis+encopresis subgroup, followed by the enuresis nocturna and encopresis subgroups. All the subgroups had higher total difficulties scores than the control group. Screening for psychiatric disorders should be performed for all children with incontinence.

SENS-U: continuous home monitoring of natural nocturnal bladder filling in children with nocturnal enuresis - a feasibility study

INTRODUCTION

Enuresis is a common problem in children. One treatment option is a wetting alarm that provides an alarm when incontinence occurs. A drawback of this approach is that the child is still awakened by wet sheets. Recently, a wearable, wireless ultrasonic bladder sensor became available, the SENS-U, which has the potential to prevent the enuretic event by waking up the child before the bladder is full. In this first feasibility study, the aim is to perform a night-time, home-based evaluation of the SENS-U in children with monosymptomatic nocturnal enuresis (MNE).

PATIENTS AND METHODS

In this study, children (6-12 years) with MNE were included for a one-night monitoring session. During the night, the SENS-U continuously (i.e. every 30 s) estimated the filling status [notifications were deactivated]. In addition, urine volume was collected in a measurement cup (or diaper weight). The total measured natural nocturnal bladder filling (NNBF) cycles was analyzed by descriptive statistics. Before and after the measurement, sleep behavior was assessed by a selection of the Children's Sleep Habits Questionnaire.

RESULTS

Fifteen patients (boys/girls: 13/2) [mean age: 8.6 ± 1.5 years] have been enrolled. One patient was excluded due to inadequate sensor-to-skin contact. For 14 children, 18 NNBF cycles were recorded (voiding diary) of which three patients (21%) had more than one NNBF cycle. The SENS-U was able to successfully detect 83% of the NNBF cycles. The three missed NNBF cycles had a voided volume ≤30 ml, which was at the lower limit of the sensor's detection range. The SENS-U had no effect on sleeping behavior.

CONCLUSION

The SENS-U was able to monitor the natural nocturnal bladder filling successfully in children with monosymptomatic nocturnal enuresis at home, without disturbing their sleep. Future research focuses on investigating the usability of the SENS-U for both diagnostic - and treatment purposes.

A novel method of rapid appraisal of clinical practice guidelines for children with enuresis

BACKGROUND

Enuresis (bedwetting) is a common but variably managed pediatric condition. Despite an abundance of published documents which provide recommendations for clinical evaluation and management of enuresis, no formal appraisal of their methodological quality has been undertaken.

OBJECTIVE

The objective of the study is to evaluate the quality of current pediatric guidelines for enuresis (bedwetting) using a novel method of appraisal.

STUDY DESIGN

A comprehensive gray literature search was undertaken to identify guideline documents that provided recommendations for management of enuresis in children and adolescents. The search strategy included guideline databases, targeted websites, Google search engines, and MEDLINE. Guideline documents included clinical practice guidelines, consensus documents, position statements, and other clinical review documents. Each document underwent basic appraisal by two independent assessors using the International Centre for Allied Health Evidence (iCAHE) Guideline Quality Checklist. Those documents which (1) had an iCAHE quality score of ≥10; (2) used a systematic search strategy; and (3) linked evidence to their recommendations underwent further detailed appraisal using the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument.

RESULTS

Eighteen documents were shortlisted for basic appraisal. The iCAHE highlighted a lack of information regarding underlying evidence and dates (mean score 36% and 41%, respectively). Only three documents met basic quality criteria and progressed to detailed appraisal using the AGREE II. These included guidelines produced by the Paediatric Society of New Zealand and National Clinical Guideline Centre and a position statement from the Canadian Paediatric Society. All three guidelines presented clear and unambiguous recommendations (mean score 80%). However, information regarding stakeholder involvement was lacking (mean score 50%).

CONCLUSIONS

Several guidelines exist for the evaluation and management of children with enuresis, but many lack appropriate methodological quality standards. The guideline produced by the National Clinical Guideline Centre achieved the highest quality rating and is recommended for future adaptation and implementation in relevant clinical settings.

An interprofessional approach to managing children with treatment-resistant enuresis: an educational review

Enuresis (intermittent urinary incontinence during sleep in a child aged ≥ 5 years) is commonly seen in paediatric practice. Despite the availability of effective interventions, treatment resistance is encountered in up to 50% of children. In this educational review we attempt to provide insight into the causes of treatment resistance, and offer practical suggestions for addressing this condition using an interprofessional approach. We explore the pathophysiology of and standard treatments for enuresis and discuss why standard treatments may fail. An interprofessional approach to treatment resistance is proposed which utilises the expertise of professionals from different disciplines to address the problems and barriers to treatment. The two interprofessional approaches include a multidisciplinary approach that involves the patient being sent to experts in different disciplines at different times to address their treatment resistance utilising the skills of the respective experts, and an interdisciplinary approach that involves a patient being managed by members of interdisciplinary team who integrate their separate discipline perspectives into a single treatment plan. Although an interdisciplinary approach is ideal, interdisciplinary teams may not be available in all circumstances. Understanding the roles of other disciplines and engaging clinicians from other disciplines when appropriate can still be helpful when treatment resistance is encountered.

Tips for managing treatment-resistant enuresis

Enuresis (bedwetting) is common in school-aged children and can impact health, psychosocial well-being and quality of life. Although effective treatment is available, treatment resistance is encountered in about 50%. This paper discusses the management of treatment-resistant enuresis from a multidisciplinary perspective. Causes of treatment resistance include lower urinary tract problems, constipation, incorrect alarm training techniques, sleep disorders including sleep apnoea and psychological comorbidities. Practical suggestions to address treatment resistance are offered utilising expertise from clinicians from different disciplines.

Primary nocturnal enuresis: Assessment and treatment at a single referral center

BACKGROUND

The aim of this study was to investigate the prevalence of primary monosymptomatic and non-monosymptomatic nocturnal enuresis (PMNE and PNMNE) and associated factors in a major referral center for NE in Abu Dhabi.

METHODS

Children referred to the Paediatric Continence Clinic, between 2014 and 2016, for PNE were included in the study. Exclusion criteria were neuropathic bladder, abnormality of the bladder and bowel, urethral stenosis, neurological and psychiatric problems, non-completion of the diagnostic protocol, and follow up <6 months.

RESULTS

A total of 128 patients were included in the study: 82 boys (64.1%) and 46 girls (35.9%). A total of 42.7% of boys and 8.7% of girls had PMNE, and 57.3% of boys and 91.3% of girls had PNMNE. Constipation was present in 46% of patients. In the male PNMNE group, 74.5% had overactive bladder (OAB), 10.6%, dysfunctional voiding (DV); and 14.9%, OAB + DV. In the female PNMNE group, 35.7% had OAB; 21.4%, DV; 40.5%, OAB + DV; and 2.4%, underactive bladder. A total of 97% and 86 of children with PMNE and PNMNE, respectively, had resolution of NE. Boys had a significantly higher incidence of PMNE, and girls, of DV.

CONCLUSION

In Abu Dhabi, NE is often associated with bladder dysfunction or DV, mostly in girls, and with constipation. High intake of dry, low fiber foods, along with hot weather and the stress of city living negatively affect the incidence of fecal retention and of NE. A multimodal approach, including the treatment of constipation, led to a satisfactory resolution of PNE in almost 90% of cases.

Childhood Enuresis: Current Diagnostic Formulations, Salient Findings, and Effective Treatment Modalities

Enuresis constitutes a frequently encountered problem area for children that may adversely affect social and emotional adjustment. This type of incontinence has been of concern to the human family for centuries. A brief history of enuresis is presented followed by current conceptualizations, diagnostic criteria, prevalence rates and psychiatric comorbidities. Historic notions of causation together with ineffective, sometimes barbaric treatments are then discussed, ending with a presentation of evidence-based treatment modalities, with the urine alarm being an essential element of effective treatment. An intervention termed dry bed training combines the urine alarm with a series of procedures designed in part to reduce relapse potential and should be a primary consideration for implementation by treatment professionals. Finally, a brief case study is presented illustrating special etiological and treatment considerations with juvenile psychiatric patients.
