The efficacy of electrical stimulation in treating children with nocturnal enuresis: A systematic review and meta-analysis

AIM

We performed a systematic review and meta-analysis to evaluate the efficacy of electrical stimulation (ES) in treating children with nocturnal enuresis (NE).

METHODS

Randomized controlled trials (RCTs) of the use of ES for the treatment of NE in children were searched using EMBASE, MEDLINE, and the Cochrane Controlled Trials Register. The references of related articles were also searched. The systematic review was carried out using the Preferred Reporting Items for Systematic Reviews and Meta-analyses.

RESULTS

Four RCTs involving 171 patients were studied. We found that there was statistically significant difference in the wet nights per week (mean difference [MD], -0.70; 95% confidence interval [CI], -0.89 to -0.51; P < .00001), the number of patients with clinical response (MD, 26.88; 95% CI, 11.16 to 64.74; P < .00001), and bladder capacity (MD, -0.70; 95% CI -0.89 to -0.51; P < .00001) in the ES group compared with the placebo group with the exception of maximum voided volume (MVV) (MD, 19.48; 95% CI, -9.18 to 48.14; P = .18).

CONCLUSIONS

The study provides a significant improvement in statistics in the wet nights per week, the number of patients with clinical response and bladder capacity for children with NE compared with the placebo group with the exception of MVV.

Rate and risk factors of nocturnal enuresis in school going children

PURPOSE

The purpose is to find out the rate of nocturnal enuresis in school going children (5-12 years) and the risk factors associated with it.

MATERIALS AND METHODS

The parents of children aged between 5 and 12 years studying in two primary schools in Ahmedabad completed a self-administered semi-structured questionnaire comprising of enuresis, sociodemographic profiles, and risk factors. Children with enuresis and those without were compared on demographic characteristics and risk factors using Chi-square and t-test for categorical and quantitative data respectively. The data were analyzed using SPSS version 17.

RESULTS

The response rate was 86.54% as 1904 responses were collected out of 2200. The overall rate of nocturnal enuresis was 6.7% (according to Diagnostic and Statistical Manual of Mental Disorders, 5th Edition definition of nocturnal enuresis). As the age increased, the rate of nocturnal enuresis declined. A positive family history was seen in 36.6% of children with enuresis. Enuresis was found to be more frequently in lower socioeconomic class. It was a neglected problem, only 20.6% of children received some kind of treatment.

CONCLUSION

The rate of nocturnal enuresis was 6.7% in school going children. Strong correlation was found with family history. Although the rate was high, most of the children with enuresis were not treated.

Are psychological comorbidities important in the aetiology of lower urinary tract dysfunction-ICI-RS 2018?

AIMS

To review studies on the comorbid psychological symptoms and disorders in patients with lower urinary tract disorders (LUTD) over the life-span, to analyse how they contribute toward the aetiology of LUTD and to discuss optimal service implementation.

MATERIALS AND METHODS

A review of relevant literature was conducted and presented during the ICI-RS meeting in 2018. Open questions and future directions were discussed.

RESULTS

On the basis of current research, there is overwhelming evidence in all age groups that psychological comorbidities are more common in patients with LUTD. Vice versa, patients with psychiatric disorders have higher rates of LUTD. The types of LUTDs and psychiatric disorders are heterogeneous. Complex aetiological models best explain specific associations of comorbidity. Irrespective of aetiology, it is advisable to address both urological and psychological issues in patients of all age groups with LUTD.

CONCLUSIONS

Psychological symptoms and disorders play a decisive role in the development of LUTD in all age groups and need to be considered in the assessment and treatment of LUTD.

Sleep and Daytime Complaints During Manic and Depressive Episodes in Children and Adolescents With Bipolar Disorder

INTRODUCTION

Depressive and manic episodes of bipolar disorder can interact with sleep complaints, followed by a worsened psychiatric condition. The aim of this study was to examine the interaction of sleep disorders with bipolar disorder in youths during depressive and manic episodes.

METHODS

The target population was children and adolescents drawn from the Children and Adolescents Affective Disorder Program. Clinical assessment for current psychiatric diagnosis was done by direct clinical interview, Diagnostic Interview for Children and Adolescents (DSM-IV), and best-estimated clinical consensus. We applied sleep questionnaires from which we obtained sleep and daytime complaints during manic and depressive episodes. All statistical tests of significance were done using 2-tailed tests with α = 0.05.

RESULTS

Participants in this study comprised 29 children (age = 10 ± 3 years, boys = 23) and 43 adolescents (age = 15 ± 2.4 years, boys = 30). Sleep complaints were observed in 66.4% of participants during manic episodes and 52.3% during depressive episodes. 37.9% of patients had sleep complaints in both episodes. Time in bed was longer during depressive episodes than manic episodes (p = 0.01). We found a high prevalence of nocturnal enuresis in depressive episodes in children and adolescents, which was statistically significant compared with manic episodes (p < 0.05). Unrested sleep was higher in adolescents in both episodes, and it was statistically significant during manic episodes (p < 0.05).

CONCLUSION

According to our analyses, the minority of patients had sleep complaints in both episodes. Our data showed that nocturnal enuresis occurred more frequently during depressive than manic episodes. Further research is necessary to understand the implications of these data.

Medical Comorbidity of Nocturnal Enuresis in Children

Introduction:

The purpose of this study was to evaluate the characteristics of patients with nocturnal enuresis (NE).

Methods:

We enrolled 403 children with NE referred to the Services of Pediatrics, Campus Bio-Medico University Hospital of Rome between June 2013 and July 2018. We excluded 2 children, respectively, with renal agenesis and chromosomopathy.

Results:

Of the 401 patients, 101 girls (25.2%) and 300 boys (74.8%), aged 5–16 years; mean age at first visit 8.8 ± 2.44 years. During the physical examination, we asked the patients and their parents specific questions to identify signs and symptoms of voiding disorders and comorbid conditions. In addition, we evaluated family history and behavioral characteristics of patients. In this study, NE was heredity in the 31.2% of cases. We found urogenital abnormalities in 15.7% of cases, constipation in 14.5% of cases, innocence heart murmur in 21.4% of cases and parasomnias in a good percentage of cases, especially snoring (13.7%), restless sleep (5.7%), somniloquy (23.7%) and bruxism (14.7%).

Conclusions:

Our experience demonstrates that there are a lot of comorbidities that are associated with NE and can influence the prognosis and the response to the therapy in these children.

Allergic rhinitis and the associated risk of nocturnal enuresis in children: a population-based cohort study

BACKGROUND

Despite controversy, an association between allergy and nocturnal enuresis (NE) has been reported for almost a century. Allergic rhinitis (AR)-associated sleep-disordered breathing frequently results in microarousals during sleep, decreased sleep efficiency, and change in sleep pattern and behavior. NE is a common sleep disorder in children. Hence, this study aimed to investigate the incidence and risk of NE in children with AR.

METHODS

A population-based cohort study was conducted among 327,928 children with AR and 327,601 non-AR controls between 2000 and 2012 in Taiwan. By the end of 2012, the incidence of NE in both cohorts, and the AR-to-non-AR cohort hazard ratios (HRs) were measured.

RESULTS

The adjusted HR of NE during the study period was 1.7-fold higher in the AR cohort compared to the non-AR cohort. The risk was greater for boys, children younger than 6 years old, those with comorbidities of asthma, atopic dermatitis, and attention deficit/hyperactivity disorder (ADHD), and those who had more than 5 AR-related medical visits per year. The risk of NE in the AR cohort decreased with follow-up time and was the highest within the first year after AR diagnosis.

CONCLUSION

Children with AR had a higher incidence and subsequent risk of NE. The risk of NE was greater for boys, younger children, and those with more frequent health utilization for AR symptoms.

Prevalence of nocturnal enuresis among children in Primary Health Care Centers of Family and Community Medicine, PSMMC, Riyadh City, KSA

Background:

Nocturnal enuresis (NE) is commonly known as any intermittent incontinence while asleep in a child being at least 5-year old. The families of the children having this disorder can be greatly worried because this disorder can lead to considerable emotional distress and some psychological consequences. This study is aimed to estimate the prevalence of NE among children and to identify the characteristics of children who has NE. The third aim is to identify the consultation pattern to solve this problem.

Methods:

A cross-sectional survey was performed in Primary Health Care Centers of Family and Community Medicine, PSMMC, Riyadh City, KSA, during 2017.

Results:

Out of 65 families that have children with NE, 38.7% was the frequency of bedwetting every night; 22.6% of the children were stressed as a result of new child birth; 14% of the families did not feel a family load of having children with NE; 29% of the families did not try to treat their children because of their improvement with time; and 12% of the families that tried to treat their children used fluid restriction and waked their children up frequently at night.

Conclusions:

The prevalence of NE was 18.5% among families with a higher prevalence in boys. Prevalence of NE decreased with increasing age with many children found of having stressful events in their life other than parents’ divorce. We would like to refer that it is important for families that have children with NE to seek medical consultation immediately, which can lead to behavioral modifications.

Assessment and treatment of nocturnal enuresis in children and young people

Nocturnal enuresis - or bed-wetting - is one of the most common chronic conditions of childhood. It has a significant effect on the quality of life of affected children and their families and is associated with several comorbidities, some of which resolve on successful treatment. The causes of this troublesome condition are explored and the principles of assessment and treatment are discussed with reference to National Institute for Health and Care Excellence guidance as well as research. Response to treatment resistance is considered and appropriate onward referral discussed.

Nocturia in Women With Obstructive Sleep Apnea

Obstructive sleep apnea (OSA) is underdiagnosed in women compared with men. Women have a tendency to underreport or present with atypical symptoms such as behavior changes, insomnia, fatigue, and depression. Nocturia, waking up from sleep 2 times or more to void, has been shown to be associated with OSA, but it is not an included symptom in commonly used screening questionnaires in primary provider offices. About 50% of patients with OSA have nocturia, and treatment of OSA improves it. Recognition of nocturia as a relevant symptom of OSA is important for primary providers to provide timely referral for the diagnosis of OSA.

Clinical features of, and association of bladder ultrasound and uroflowmetry with, overactive bladder recovery period in children

BACKGROUND

Overactive bladder (OAB) is a symptomatic syndrome defined by urinary urgency, usually accompanied by increased urination frequency and nocturia, with or without urinary incontinence. The prevalence of pediatric OAB in 5-13 year olds is as high as 16.6%, but the pathophysiology and epidemiology have not been sufficiently elucidated.

METHODS

We retrospectively reviewed medical records in 117 children with OAB aged between 5 and 15 years during the years 2012-2016. At initial presentation, abdominal ultrasound and uroflowmetry were performed, and behavioral modifications, such as timed voiding, and constipation therapy were initiated. If there was no response after 4 weeks, antimuscarinic treatment was added. We evaluated the clinical features of OAB and factors related to the recovery period, which was defined as the period from the start of behavioral modifications to cure.

RESULTS

The average recovery period was 11.9 ± 9.73 months. There was no significant difference in the recovery period according to age, gender, percentage of urination frequency, nocturnal enuresis, or constipation. The recovery period was significantly shorter in the group with bladder wall thickness ≥5 mm than with bladder wall thickness <5 mm. Children with a tower-shaped curve on uroflowmetry had a significantly shorter recovery period than those with a bell-shaped curve.

CONCLUSIONS

Bladder wall thickness and uroflow curve shape are related to the recovery period of pediatric OAB.

Can Seasons be an Etiologic Factor for Monosymptomatic Nocturnal Enuresis?

Introduction

Primary nocturnal enuresis is the most frequent urinary system complaint among pediatric patients. 

Material and Methods

Data compiled from 5,500 children, aged between five to 16 years, diagnosed with enuresis during the period from January 2010 to December 2015 were analyzed. The inclusion criteria were having a diagnosis of monosymptomatic nocturnal enuresis, a birth date known for certain, and complete family history taken. A total of 3,547 children met the inclusion criteria and were included in the study. The study was performed by retrospective analyses. 

Results

Analysis of the results revealed a statistically significant difference among the rates of enuresis with respect to months and seasons (p < 0.001). In our study, we retrospectively reevaluated 3,500 patients for their birth dates and determined a statistically significant difference in the rates of nocturnal enuresis with respect to seasons (p < 0.001). 

Conclusion

As a result of this study, we determined that monosymptomatic nocturnal enuresis in children is more frequent, particularly in those born during the summer months.

Assessment and management of urinary incontinence in women

Urinary incontinence is a common and usually hidden issue that can affect women of all ages. It is often ignored by the patient because of their misconception that incontinence is an inevitable consequence of ageing and their low expectations of successful treatment. There are various types of incontinence, with symptoms that can significantly affect patients' quality of life. This article aims to enhance nurses' understanding of the types of urinary incontinence affecting women, associated risk factors and continence assessment, as well as the initial investigations and conservative treatments that can be instigated by general nurses. It also discusses some of the advanced treatments offered by specialist services. The article emphasises the importance of undertaking a holistic continence assessment to ensure appropriate continence care is provided, and how tailoring this care to the individual can improve adherence to treatment plans.

Herbal medicine (Suoquan) for treating nocturnal enuresis: A protocol for a systematic review of randomized controlled trials

BACKGROUND

Suoquan is widely used to treat frequent urination, enuresis, and other diseases caused by kidney qi deficiency. Many clinical trials assessing the efficacy and safety of Suoquan for the treatment of enuresis have been reported. This review will assess the clinical evidence for and against the use of Suoquan as a treatment for enuresis.

METHODS AND ANALYSIS

Fourteen databases will be searched until 2018. We will include randomized controlled trials (RCTs) examining Suoquan decoctions for any type of enuresis. All RCTs of decoctions or modified decoctions will be included. The methodological qualities of the RCTs will be assessed using the Cochrane Collaboration tool for assessing risk of bias.

ETHICS AND DISSEMINATION

This systematic review will be published in a peer-reviewed journal. The review will be disseminated both electronically and in print. It will be updated to inform and guide healthcare practices.

Association of pediatric obstructive sleep apnea with poor academic performance: A school-based study from India

BACKGROUND

Pediatric obstructive sleep apnea (OSA) is a highly prevalent but often neglected disorder. There is paucity of reports on the prevalence of pediatric OSA from India. This study was done to estimate the prevalence of OSA in school children aged 5-10 years and its association with academic performance.

METHODOLOGY

This school-based cross-sectional epidemiological study was conducted from July 2015 to November 2015. A questionnaire seeking information on sociodemographic variables, school performance, sleeping pattern, and a validated 22-item pediatrics sleep-related breathing disorder (SRBD) scale was distributed to 1820 pupils in three primary schools. The prevalence of OSA (defined as SRBD score >33%) was reported as proportion and its 95% confidence interval (CI).

RESULTS

We received 1520 questionnaires out of 1820 distributed and of which 1346 were complete and were analyzed. The prevalence of OSA among children in our study was 9.6% (95% CI: 8.1%-11.7%). On multivariate analysis, working mother (adjusted odds ratio [OR]: 1.8; 95% CI: 1.2-2.7), sleep bruxism (adjusted OR: 1.7; 95% CI: 1.1-2.6), and sleep talking (adjusted OR: 3.0; 95% CI: 1.9-4.7) were found to be independently associated with OSA. Students with positive SRBD were more prone to nocturnal enuresis (NE) (OR 3.48; 95% CI 2.27-5.26) and poor academic performance in all subjects.

CONCLUSION

OSA is highly prevalent (9.6%) in Indian children. OSA is associated with NE and poor academic performance in all subjects. This study found association of maternal occupation and OSA which needs to be confirmed in larger studies.

Risk Factors of Nocturnal Enuresis in Children with Attention Deficit Hyperactivity Disorder

BACKGROUND

Presence of attention deficit hyperactivity disorder (ADHD) has a negative effect on the resolution of incontinence; however, there are few studies which investigated the risk factors of nocturnal enuresis (NE) in patients with ADHD.

AIMS

This study was conducted to investigate the prevalence of NE and its risk factors in children with ADHD.

METHODS

331 children, aged 6 to 10 years, diagnosed as having ADHD were enrolled in this study. The diagnosis of ADHD was confirmed by an experienced child and adolescent psychiatrist according to DSM-IV-TR. NE was defined as nighttime wetting with or without daytime incontinence, at least twice a week over a period of 3 months or longer in children 5 years old and older without anatomical abnormalities. Details on demographic data, perinatal history, medical history and developmental history were collected from parents or medical records.

RESULTS

Most of the ADHD patients with inattentional subtype (77.5%) had NE, compared to 31.7% in the hyperactive/Impulsive subtype and 22.5% in the combined subtype (p<0.001, t=42.71). Among children with enuresis, there were significantly higher rates of history of familial enuresis (26% vs. 18 %, p<0.001, t=16.9), cesarean delivery (47% vs. 33%, p=0.019, t=5.84) and history of neonatal sepsis (16% vs. 7%, p=0.018, t=5.62) than non-NE children. Moreover, patients with NE had lower birth weight than non-NE patients (2.93(0.65) vs. 3.09 (0.46), p=0.026, t=2.51). Also, low parental education was associated with increase in the rate of NE.

CONCLUSION

Children with ADHD have a high prevalence of NE. Male sex, low education level of parents, history of neonatal sepsis, positive family history of NE, low birth weight and caesarian delivery may be risk factors for NE in ADHD children. Most ADHD patients with inattentional subtype had NE.

Enuresis Management in Children: Retrospective Clinical Audit of 2861 Cases Treated with Practitioner-Assisted Bell-and-Pad Alarm

OBJECTIVE

To establish the treatment efficacy of practitioner-assisted bell-and-pad alarm therapy in children with enuresis between the ages of 5 and 16 years by retrospective medical chart review of 2861 children in multiple clinical settings.

STUDY DESIGN

This review was conducted across 7 Australian clinical practices. The primary outcome measure was the time taken for children with either primary, secondary, monosymptomatic, or nonmonosymptomatic enuresis to be dry for 14 consecutive nights. The secondary outcome measure was to determine relapse rates, defined as 1 symptom recurrence per month post interruption of treatment. Data were analyzed by correlation and χ² test via IBM SPSS Statistics (version 22).

RESULTS

The overall success rate of the bell and pad treatment was 76%, irrespective of age. The mean treatment time to achieve dryness was 62.1 ± 30.8 days, and the relapse rate was 23%. Concurrent bowel dysfunction was associated with a slightly lower success rate (74%). Concurrent lower urinary tract symptoms were associated with a lower success rate (73%) and greater relapse (1.75 times more likely to relapse). Children with secondary enuresis had significantly greater success than those with primary enuresis (82% vs 74%).

CONCLUSION

The type of alarm therapy reported in this study is highly effective. This study will provide the basis for clinical guidelines and practice tools for clinicians, which will help to reduce variation in care pathways for alarm treatment for enuresis.

Morphometric Magnetic Resonance Imaging Study in Children With Primary Monosymptomatic Nocturnal Enuresis

OBJECTIVE

Primary monosymptomatic nocturnal enuresis (PMNE) refers to bed-wetting in children who have no other lower urinary tract symptoms and are never dry for more than 6 months. Our previous studies demonstrated that children with PMNE exhibited brain functional abnormalities compared with healthy controls; however, researches on the abnormalities in gray matter were limited. This study aimed to investigate brain structural changes in gray matter of children with PMNE using magnetic resonance imaging (MRI).

METHODS

Gray matter volumes (GMVs) and gyrification indices (GIs) were calculated using voxel-based and surface-based morphometry analyses of structural MRI data acquired from 26 children with PMNE and 28 healthy children. To identify between-group differences in gray matter, two-sample t-tests were conducted on GMV and GI images separately.

RESULTS

Compared with the controls, children with PMNE showed significantly increased GMVs in the supplementary motor area and medial prefrontal cortex regions (mean GMV in PMNE: 0.54 ± 0.07 l; mean GMV in controls: 0.50 ± 0.06 l) and reduced GIs in the right precuneus (mean GI in PMNE: 25.74° ± 2.34°; mean GI in controls: 27.97° ± 1.79°).

CONCLUSION

Children with PMNE showed abnormal GMVs in frontal lobe and GIs in precuneus, and these changes might be involved in the pathological mechanism of PMNE.

How often does urinary incontinence really affect primary school children?

OBJECTIVE

Introduction: Urinary incontinence should be treated as a pathology in patients who are at least 5 years old, a few percent of patients continue to suffer from this disorderin adolescence. It can be qualified as day-time incontinence (DUI) and nocturnal-incontinence (enuresis-NE). The aim: To assess the incidence of micturition disorders in children aged 7 to 10, to analyze accompanying symptoms and compare the results with previous studies.

PATIENTS AND METHODS

Material and methods: Parents of 954 children (491 girls and 463 boys) were surveyed during parent-teacher meetings held in 2017 in 11 randomly selected schools in southern Poland. The questionnaire was based on International Children's Continence Society guidelines. Study population was divided into subgroups according to demographical data, presence of accompanying symptoms and the type of micturition disorder.

RESULTS

Results: Minor wetting was common in the studied population, however the group of children with clinically significant incontinence becomes smaller after applying current ICCS criteria. ≥1 symptom of urinary bladder malfunction was reported in 18% of cases (17.5% girls and 18.8% boys). Significant (≥1/month) NE was present in 1,7 % of children and significant (≥1/month) DUI in 2,2%. Significant NE combined with significant DUI occurred in 1% of children. Relationships between incontinence and the age at which children stopped wearing diapers, urinary tract infections, soiling and constipation episodes were observed.

CONCLUSION

Conclusions: Unified and clearly defined terminology should be used in order to correctly describe and compare the scale of this problem. Urinary incontinence should not be underestimated, because if untreated it may lead to physical, psychological and social disorders.

Effect of traditional Chinese and Western medicine on nocturnal enuresis in children and indicators of treatment success: Randomized controlled trial

BACKGROUND

Nocturnal enuresis (NE) is a common pediatric developmental disorder. Desmopressin is frequently used for NE and is an evidence-based therapy. Suoquan capsule is a Chinese medicine commonly used for treating NE in children but is poorly understood by most scholars.

METHODS

A total of 369 children with NE were randomized to receive either suoquan, desmopressin plus suoquan, desmopressin, or behavioral intervention for 2 months, and the response rates evaluated. Subsequently, the viable demographic factors that could lead to success were investigated on logistic regression analysis. Moreover, after 3 months of follow up, the relapse rate was investigated.

RESULTS

The complete response (CR) rate in the desmopressin plus suoquan group (37.5%) was higher than that in the behavioral intervention group (6.3%, P < 0.007). The desmopressin group had a lower CR rate (22.5%) and a higher non-response rate (25.0%) than the desmopressin plus suoquan group (non-response rate, 21.9%; P > 0.007). The relapse rate in the desmopressin group was significantly higher than that in the desmopressin plus suoquan group (72.2% vs. 30.6%, P < 0.007). On Multivariate analysis, treatment group, NE frequency, and age were independent predictors of CR at 2 months (P < 0.05).

CONCLUSIONS

Combined traditional Chinese and Western treatment in children with NE is effective and has a low relapse rate. NE frequency, treatment method, and age are important predictive factors for CR after treatment.

Recent advances in managing and understanding enuresis

Enuresis, particularly in children during sleep, can be a debilitating condition, affecting the quality of life of the child and his or her family. The pathophysiology of nocturnal enuresis, though not clear, revolves around the inter-related mechanisms of overactive bladder, excessive nocturnal urine production, and sleep fragmentation. The first mechanism is more related to isolated nocturnal voiding, whereas the latter two are more related to nocturnal enuresis, in which circadian variations in arginine vasopressin hormone play a key role. A successful treatment would depend upon appropriately addressing the key factors precipitating nocturnal enuresis, necessitating an accurate diagnosis. Thus, advancements in diagnostic tools and treatment options play a key role in achieving overall success. This review summarizes recent advances in understanding the pathophysiology of nocturnal enuresis, diagnostic tools, and treatment options which can be explored in the future.

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.

Clonidine may have a beneficial effect on refractory nocturnal enuresis

BACKGROUND

Although the evidence-based treatment for nocturnal enuresis is established, nearly one-third of patients are still enuretic with desmopressin, anti-cholinergic treatment and alarm. The fourth option, imipramine, is limited because of the risk of cardiotoxicity on overdose. Clonidine, an α₂ -adrenoceptor agonist that also has noradrenergic effects like imipramine, is a new option for refractory enuresis.

METHODS

A total of 148 patients (6-14 years of age; mean, 9.1 years) with refractory enuresis under desmopressin, anti-cholinergic treatment and alarm were enrolled. The patients consisted of 100 boys and 48 girls, of whom 23 had monosymptomatic nocturnal enuresis and 125 had non-monosymptomatic nocturnal enuresis. Clonidine 4 μg/kg/day (maximum, 75 μg/day) orally 30 min before bedtime was added and its effects were evaluated after 4 weeks of treatment.

RESULTS

A total of 83 patients (56.1%) achieved partial or complete response with the additional clonidine. No significant adverse reactions were noted.

CONCLUSIONS

Clonidine could be an aid for refractory enuresis, although further randomized controlled trials are needed.

Primary nocturnal enuresis is associated with lower intelligence quotient scores in boys from poorer socioeconomic status families

OBJECTIVES

To explore intelligence quotient in boys with primary nocturnal enuresis compared with normal boys considering their socioeconomic status.

METHODS

A total of 152 school-aged boys (including 55 boys with primary nocturnal enuresis and 97 matched normal controls) were assessed. Boys with a history of any neurological or urological disease were excluded. Two different districts of Tehran: Khani-Abad (a poor district) and Pirouzi (a middle class district) districts were enrolled according to socioeconomic status data reported by the World Health Organization. Intelligence tests were carried out using a validated Iranian translation of the Wechsler Intelligence Scale for Children Revised. Total, as well as performance intelligence quotient and verbal intelligence quotient scores and verbal-performance discrepancy (the difference between verbal and performance intelligence quotient scores for each individual) were compared using a t-test between boys with primary nocturnal enuresis in each district and their matched controls.

RESULTS

Considering each district separately, the total intelligence quotient score was lower in primary nocturnal enuresis cases than controls only in the lower income district (90.7 ± 23.3 vs 104.8 ± 14.7, P = 0.002). Similarly, boys with primary nocturnal enuresis ranked lower in verbal intelligence quotient (P = 0.002) and performance intelligence quotient (P = 0.004) compared with their matched normal controls only in lower income district, whereas in the higher income district, boys with primary nocturnal enuresis ranked similar in total intelligence quotient to their matched controls.

CONCLUSIONS

Boys with primary nocturnal enuresis had a lower intelligence quotient compared with the control participants only in low-income district. It seems important to adjust the results of the intelligence quotient assessment in these children according to their socioeconomic status.

Atomoxetine ameliorates nocturnal enuresis with subclinical attention-deficit/hyperactivity disorder

BACKGROUND

Recent studies have shown that incontinence and attention-deficit/hyperactivity disorder (ADHD) coexist and there is an interaction between them. The treatment for nocturnal enuresis (NE) and ADHD, however, has not been established.

METHODS

At the first visit to the outpatient clinic, physical examination and history taking were carried out in 265 new patients with NE. After excluding the possibility of comorbid ADHD and related disorders, patients with monosymptomatic NE (MNE) were treated with desmopressin and/or alarm, and those with non-monosymptomatic NE (NMNE) were treated with anti-cholinergics and/or alarm. This 12 week treatment did not work in 65 patients, and they were re-assessed for comorbid ADHD. A total of 24 were diagnosed with ADHD, and they were treated with atomoxetine (1.8 mg/kg/day) in addition to ongoing therapy for NE.

RESULTS

After 8 weeks of atomoxetine, the average wet nights per months was significantly decreased: 18.5-4.6 in the MNE group (P = 0.001), and 22.1-12.4 in the NMNE group (P = 0.0251). Overall, atomoxetine was beneficial in 19 of 24 patients.

CONCLUSIONS

Atomoxetine may be a suitable option for refractory NE with comorbid ADHD.

Early Behavioral Risks of Childhood and Adolescent Daytime Urinary Incontinence and Nocturnal Enuresis

OBJECTIVE

To investigate whether infant temperament and childhood internalizing, externalizing, and inattention symptoms increase the likelihood of daytime urinary incontinence or nocturnal enuresis at 10 years and adolescence (11.9-17.8 years).

METHOD

Data were from a longitudinal cohort of 1119 healthy Chilean children. We assessed behavioral symptoms at infancy, 5 years, and 10 years and their relationship with subsequent daytime urinary incontinence and nocturnal enuresis.

RESULTS

Daytime urinary incontinence and nocturnal enuresis occurred in, respectively, 3.3% and 11.4% at 10 years and 1.1% and 2.7% at adolescence. Difficult infant temperament was associated with increased odds of 10-year daytime urinary incontinence. Inattention at 5 years was associated with increased odds for nocturnal enuresis at 10 years and adolescence. Internalizing and externalizing symptoms at 5 years were associated with increased odds of 10-year daytime urinary incontinence and nocturnal enuresis. Internalizing and externalizing symptoms at 10 years were associated with adolescent nocturnal enuresis.

CONCLUSION

Temperament and internal/externalizing symptoms may be risk factors for school-age and adolescent urinary incontinence.

Evaluation of behavioral problems in patients with monosymptomaticnocturnal enuresis: a prospective controlled trial

BACKGROUND/AIM

The aim of the present study was to evaluate the behavioral and emotional patterns of patients with nocturnal enuresis (NE) and compare them with those of healthy subjects.

MATERIALS AND METHODS

Thirty-eight children and adolescents with monosymptomatic NE who were admitted to our hospital's pediatric and urologic outpatient clinics and 46 age-matched, healthy subjects were enrolled in this study. To compare behavioral patterns in these patients, the Child Behavior Checklist (CBCL) was used. Patients' ages, occupations, educational, and socioeconomic status, and mothers' age at delivery were compared in the two groups. One-way ANOVA was used for statistical analysis.

RESULTS

Enuretic children were found to have more behavioral problems than nonenuretic children with regard to social (P = 0.008) and attention (P = 0.018) problems. There were no significant differences in anxiety or attractiveness problems between the groups (P > 0.05); however, patients with enuresis were more likely to exhibit these behavioral problems than healthy subjects. The demographics of the patients were significantly different in the two groups in favor of the control group.

CONCLUSION

It was shown that patients with enuresis have more social and attention problems than the control group. Treating these patients effectively will increase the likelihood that they will not develop behavioral problems.

Stressful Events in Early Childhood and Developmental Trajectories of Bedwetting at School Age

Objective To examine whether early stressful events are associated with developmental trajectories of bedwetting. Methods This is a prospective cohort study comprising 8,761 participants from the Avon Longitudinal Study of Parents and Children. Stressful events were measured using a maternal questionnaire completed at 3 time points before their child was 4 years old. The association between stressful events and trajectories of bedwetting from 4 to 9 years was examined using multinomial regression. Results The association with stressful events was strongest for the frequent persistent bedwetting trajectory (wetting at least twice a week up to age 9). A 1 standard deviation increase in the stressful events score was associated with a 29% (13–47%) increase in the odds of experiencing frequent persistent bedwetting compared with normal attainment of nighttime bladder control. Conclusions Clinicians and parents should be aware that continence is a developmental outcome that is associated with high levels of stress in the family.

Desmopressin versus Oxybutynin for Nocturnal Enuresis in Children in Bandar Abbas: A Randomized Clinical Trial

Background

Nocturnal enuresis is among the most common disorders in children. Several pharmacological and non-pharmacological treatments are available for nocturnal enuresis. Studies for reaching the best pharmacological treatment for this disorder are continuing.

Objective

To compare the effectiveness and safety of Desmopressin and oxybutynin for treatment of nocturnal enuresis in children from Bandar Abbas in 2014.

Methods

This randomized controlled trial was conducted in 2014 and participants included 66 children with nocturnal enuresis who were more than 5 years old. Patients were randomly assigned into two groups. The first group received 120 microgram Desmopressin daily for 2 months, then 60 microgram daily for 2 months, then 60 microgram every 2 days. The second group received 5 mg oxybutynin twice a day for 6 months. The patients were followed after 1, 3, and 6 months to track treatment response. The study outcomes were frequency of nocturnal enuresis, urinary incontinency, urgency, and frequency. Data were analyzed using SPSS software.

Results

There were no significant differences between the two groups with respects to sex, age, place of residence, and parents’ education (p<0.05). Nocturnal enuresis, incontinency, urgency, and frequency of nocturnal enuresis was significantly lower with Desmopressin treatment in comparison to the oxybutynin treated group after 1 and 3 months (p<0.05). In addition, constipation and xerostomia were more frequent among the oxybutynin group after 1, 3, and 6 months (p<0.01). Blurred vision was also more frequent among oxybutynin group after 3 months (p<0.01). After 6 months the frequency of nocturnal enuresis and its frequency was higher in oxybutynin group in comparison to the Desmopressin group (p<0.05).

Conclusion

Desmopressin is more effective and has lower rate of side effects in comparison to oxybutynin for treatment of nocturnal enuresis. We recommend using Desmopressin for treatment of nocturnal enuresis in children. More studies are needed to achieve the best pharmacological treatment option for treatment of nocturnal enuresis.

Impact of adenotonsillectomy on nocturnal enuresis in children with sleep-disordered breathing: A prospective study

OBJECTIVES/HYPOTHESIS

To investigate the relationship between sleep-disordered breathing (SDB) and nocturnal enuresis (NE) in children and to prospectively evaluate the effectiveness of adenotonsillectomy on resolving enuresis in indicated SDB patients with NE.

METHODS

We prospectively collected data from 183 children (121 males, mean age 8.17 ± 2.84 years) who underwent adenotonsillectomy to treat SDB between July 2011 and July 2013, and analyzed the prevalence of NE. Before and 3 months after surgery, all parents were requested to answer a self-reported SDB scale questionnaire (22 questions, 0-22 points) and a NE questionnaire (episodes of enuresis per month). Paired t test, Student t test, and Chi-square test were used to analyze the data.

RESULTS

Overall prevalence of NE was 9.3% (17 patients) preoperatively and 1.5% postoperatively (four patients). After adenotonsillectomy, prevalence of NE and the mean SDB scale were significantly decreased (both P values < 0.001). After adenotonsillectomy, 13 of the 17 NE patients (76.5%) showed complete resolution. There was significantly higher prevalence of NE in patients with obstructive sleep apnea (OSA) than those without OSA (13.1%, 14 of 107 vs. 3.9%, 3 of 76; P = 0.036).

CONCLUSION

There is strong association between NE and SDB, and adenotonsillectomy can markedly improve enuresis in the majority of children with NE and SDB.

Association between Asthma and Primary Nocturnal Enuresis in Children

PURPOSE

Enuresis, sleep respiratory disorders and asthma compromise the quality of sleep in children and may occur in association with each other. An association between sleep respiratory disorders and enuresis has already been demonstrated. According to united airways disease abnormalities of the upper and lower airways may coexist. A child who wheezes has a greater chance of snoring and having obstructive sleep apnea. Since asthma and sleep respiratory disorders may be associated, and sleep respiratory disorders are associated with enuresis, we determined the possibility of an association between asthma and enuresis.

MATERIALS AND METHODS

Between August 20 and March 2015 parents/guardians of children 6 to 14 years old from 16 elementary schools in our area were randomly chosen for study. Children with nonmonosymptomatic enuresis and urological or neurological disease were excluded. The Tucson and ISAAC (International Study of Asthma and Allergies in Childhood) questionnaires were used to assess sleep respiratory disorders and asthma, respectively.

RESULTS

A total of 523 children (283 males and 240 females) with a mean ± SD age of 9.42 ± 2.46 years were included in analysis. The overall prevalence of enuresis was 15.87% (95% CI 12.98-19.26). Asthmatic children with wheezing in the last 12 months were 2.33 times more likely to have had enuresis at some point in life (OR 2.33, 95% CI 1.37-3.95, p = 0.0017). If enuresis was present, the chance increased to 2.78 (95% CI 1.38-5.61, p = 0.0041). Enuretic children were 5.34 times more prone to have apnea reported by parents (95% CI 2.19-13.03, p = 0.0002).

CONCLUSIONS

These findings demonstrate that asthma as well as sleep respiratory disorders is associated with primary nocturnal enuresis.

Noctural Enuresis as a Risk Factor for Falls in Older Community Dwelling Women with Urinary Incontinence

PURPOSE

We determined the association of urinary symptoms with fall risk and physical limitations in older community dwelling women with urinary incontinence.

MATERIALS AND METHODS

We performed an in-depth assessment of daytime and nighttime urinary symptoms, fall risk, physical function, physical performance tests and mental function in older community dwelling women with urinary incontinence who had not sought care for urinary symptoms. All assessments were performed in participant homes. We used univariable and multivariable linear regression to examine the relationship of urinary symptoms to fall risk, physical function and physical performance.

RESULTS

Of 37 women with a mean ± SD age of 74 ± 8.4 years who had urinary incontinence 48% were at high risk for falls. Nocturnal enuresis was reported by 50% of the women. Increased fall risk was associated with increasing frequency of nocturnal enuresis (p = 0.04), worse lower limb function (p <0.001), worse upper limb function (p <0.0001) and worse performance on a composite physical performance test of strength, gait and balance (p = 0.02). Women with nocturnal enuresis had significantly lower physical performance test scores than women without nocturnal enuresis (median 7, range 0 to 11 vs 9, range 1 to 12, p = 0.04). In a multivariable regression model including age, nocturnal enuresis episodes and physical function only physical function was associated with an increased fall risk (p <0.0001).

CONCLUSIONS

Nocturnal enuresis is common in older community dwelling women with urinary incontinence. It may serve as a marker of fall risk even in women who do not seek care for urinary symptoms. Interventions targeting upper and lower body physical function could potentially decrease the risk of falls in older women with urinary incontinence.

Overactive bladder in adults with sickle cell disease

AIMS

To characterize the prevalence and impact of nocturnal enuresis and overactive bladder (OAB) symptomatology in the adult sickle-cell disease (SCD) population.

METHODS

We performed a single-center, cross-sectional study of adult SCD patients from October 2012 to February 2014, using the validated Pfizer OAB short form questionnaire and brief voiding history surveys. Patient responses and scores were compared to that of controls having normal or sickle cell trait hemoglobin genotypes.

RESULTS

A group of 239 SCD patients (116 males, 123 females) were compared with 104 normal and 57 sickle cell trait patients. Seven of 239 (2.9%) SCD patients compared to none of the 161 patients without SCD (P = 0.04) reported current nocturnal enuresis. The median age of nocturnal enuresis cessation was higher in SCD patients (12.0, IQR 9.0-15.0 years) compared to that of both normal (7.5, IQR 6.0-9.8 years) and sickle cell trait (7.5, IQR 6.0-8.8 years) groups (P < 0.0001). Ninety-three of 239 (38.9%) SCD patients compared to 17 of 104 (16.3%) normal and 11 of 57 (19.3%) sickle cell trait had scores indicating OAB symptomatology (P < 0.0001). Patients with SCD had higher OAB symptom severity and lower health-related quality of life (HRQL) scores compared to the normal and sickle cell trait groups (P < 0.0001 and P < 0.0001, respectively).

CONCLUSIONS

We demonstrate an elevated rate of nocturnal enuresis and OAB symptoms in the adult SCD population. An OAB phenotype may be an under-recognized complication of SCD irrespective of age. Neurourol. Urodynam. 35:642-646, 2016. © 2015 Wiley Periodicals, Inc.

TRANSITORY CONSECUTIVE ESOTROPIA AFTER AMITRIPTYLINE TREATMENT FOR NOCTURNAL ENURESIS -CASE REPORT

We report the case of a 9-year-old child operated for intermittent exotropia and V-pattern with a good result 2 months after bilateral Lateral Rectus Muscle Recession. The binocular vision was restored in primary position and down-gaze with excellent stereopsis at near and distance and a deviation of +4 PD in primary position. Three months later, the patient developed a consecutive esotropia of + 18 PD in primary position with diplopia in all gazes triggered by Amitriptyline treatment prescribed one month earlier for nocturnal enuresis. Diplopia was solved in time after anticholinergic medication cessation. During the recovery period, Fresnell prisms have been used in order to eliminate diplopia. Three months after diplopia onset, the binocular vision was restored showing a transitory and reversible effect of the Amitriptyline treatment. Fusion vulnerability can be a possible risk factor in developing diplopia and esotropia in patients treated with anticholinergic drugs.

The Prevalence and Sociodemographic Risk Factors of Enuresis Nocturna among Elementary School-age Children

Introduction and Aim:

Many etiological reasons are blamed for enuresis nocturna (EN). The aim of this study was to research prevalence and severity of EN among elementary school-age children and sociodemographic risk factors related to it.

Materials and Methods:

The study was performed in three elementary schools in Ankara, Turkey between January and May 2011. It was planned to have 2500 students of 6–14 ages in the study. The questionnaire, which consisted of questions, aiming to evaluate the EN condition of participants and their characteristics, were distributed to the parents. It was observed that 2314 participants’ questionnaires (92.56%) were in accordance with evaluation criteria.

Statistical Analysis:

The relation between EN and the sociodemographic factors was evaluated through Chi-square test and logistic regression analysis.

Results:

The mean age of 2314 participants was 9.21 ± 2.08. 48.5% (n = 1123) of the students were male and 51.5% (n = 1191) were female. While the general EN prevalence was 9.9% (n = 230); 10.7% (n = 120) for males, as 9.2% (n = 110) for females. Statistical significant difference was determined between the two groups, with EN and without EN, regarding age groups (P < 0.001), education level of parents (P < 0.001, P < 0.001), and the number of sibling (P = 0.002), income level (P < 0.001), and positive family history (P < 0.001). However, logistic regression analysis revealed that there was a significant difference only between EN and age groups (odds ratio [OR] =4.42, P < 0.001), education level of mother (OR = 2.13, P = 0.017) and family history (OR = 0.12, P < 0.001).

Conclusions:

As a consequence, such factors as age groups, education level of parents, positive family history could be accepted as a risk of concerning EN. It is important to perform a detailed evaluation on population, carrying risk of having EN.

Nocturnal enuresis: A topic review and institution experience

The objective is to provide a review of nocturnal enuresis (NE), including its epidemiology, etiology, pathophysiology, evaluation, and current management. We also set to provide further insight on the treatment of this condition from the experience derived from patients cared for at our tertiary-care institution. NE affects approximately 15% of all children at 5-year-old, affecting boys more frequently than girls. At our large university tertiary pediatric urology center, NE and incontinence, in general, is one the most common chief complaints prompting urologic care. In this review, we examine the condition in detail, highlighting specific goals of the initial evaluation and treatment. We contrast the commonly implemented treatment recommendations, available from the literature with strategies we have found valuable from our extensive experience in treating patients with this disorder. Using current urologic reference textbooks, book chapters, Medline, journal articles and reviews describing the many aspects of NE were reviewed in order to describe NE and the current practices at our institution. Although, this is not a systematic literature review, it includes relevant available research, institutional experience and urological expert opinion and current practices at a tertiary state health facility. The treatment of NE remains a challenge for many pediatricians and pediatric urologists. This likely stems from the multiple possible etiologies of the disorder. We have established a treatment algorithm at our institution, which we have found successful in the majority of our patients. This consists of starting patients on urotherapy, then offering both the enuresis alarm device and medication therapy as first line treatments, and finally adding anticholingerics for combination therapy. Our hope is with further research the treatment of NE will continue to improve.

Specific behavioral comorbidity in a large sample of children with functional incontinence: Report of 1,001 cases

AIMS

Psychological comorbidity among children with functional incontinence is high: 20-30% of children with nocturnal enuresis (NE), 20-40% of those with daytime urinary incontinence (DUI) and 30-50% of those with fecal incontinence (FI) have clinically relevant comorbid disorders. The aim of this study was to analyze specific comorbid behavioral symptoms for different subtypes of incontinence in a large group of children.

METHODS

All 1,001 consecutive children and adolescents (67.5% boys) with a mean age of 8.5 years presented at a tertiary outpatient department between 2004 and 2011 were examined with a full pediatric and child psychiatric assessment. Prevalence of different subforms of incontinence and associated behavioral symptoms were analyzed. The internalizing, externalizing, and total problem scores of the Child Behavior Checklist (CBCL) were evaluated.

RESULTS

Of all children, 70.1% (702 children) had NE, 36.1% (361 children) had DUI, and 36.8% (368 children) were affected by FI. More than 43% of all children had clinically relevant psychological symptoms (CBCL total score, cut-off at 90th percentile). Children with non-retentive FI had highest rates of clinically relevant psychological symptoms (58.8%). Children with combined subtypes of incontinence (any combination of NE, DUI, and FI) were more affected by psychological comorbidities than children with isolated subtypes (NE or DUI or FI).

CONCLUSIONS

Children with incontinence have high rates of comorbid behavioral symptoms-three to six times higher than norms. Especially children with FI and combined subtypes of incontinence were affected. As behavioral symptoms and disorders will interfere with incontinence treatment, a general screening is recommended.

Effects of maxillary expansion and placebo effect of appliances on nocturnal enuresis - preliminary results

Introduction

Nocturnal enuresis has been found a common symptom among children with breathing problems and sleep apnea. The purpose of this study was to evaluate the therapeutic and placebo effects of slow maxillary expansion on nocturnal enuresis.

Material and methods

Four children with enuresis aged 7–12 years were selected. Rigid acrylic expansion appliances were fabricated and delivered to them. Frequency of enuresis was recorded by the parents during three stages: 1) before appliance delivery; 2) after appliance insertion without expansion; and 3) during expansion and retention.

Results

The frequency of wetting decreased significantly during the period of appliance use without expansion. During the expansion and retention phase, two patients became completely dry, and two patients improved significantly.

Conclusions

Maxillary expansion can have a positive effect on the treatment of nocturnal enuresis. Also, the placebo effect of the expansion appliance has significant effects on enuresis.

Sleep apnea in children with refractory monosymptomatic nocturnal enuresis

BACKGROUND

Children with nocturnal enuresis (NE) are believed to have deep sleep with high arousal threshold. Studies suggest that obstructive sleep apnea-hypopnea syndrome (OSAHS) and NE are common problems during childhood. We sought to assess the prevalence of OSAHS in children with refractory NE and whether its severity is associated with the frequency of bedwetting.

METHODS

The study group comprised 43 children with refractory monosymptomatic NE and a control group of 30 children, both aged 6-12 years. All subjects underwent thorough neurological examination, one night of polysomnography only for the patient group, and a lumbosacral plain X-ray to exclude spina bifida.

RESULTS

The groups were well matched. Two subjects of the control group had mild OSAHS. The mean age of the patients was (9.19±2.4 years), 26 were boys, and 67% showed frequent NE (>3 days bedwetting/week). Patients with NE had significantly higher rates of OSAHS (P<0.0001); three patients had mild, 12 had moderate, and eleven showed severe OSAHS. There was no significant statistical difference among patients having OSAHS in relation to age, sex, or family history of NE. The frequency of bedwetting was statistically significantly higher in patients with severe OSAHS (P=0.003).

CONCLUSION

Patients with refractory NE had a significantly higher prevalence of OSAHS with no sex difference. The frequency of bedwetting was higher in patients with severe OSAHS.

Mono-symptomatic nocturnal enuresis in lebanese children: prevalence, relation with obesity, and psychological effect

INTRODUCTION

Nocturnal enuresis is involuntary urination while sleeping after a certain age, usually five years, when children should have established bladder control. The prevalence has been found to be up to 20% in five year old children, and it is considered the most common urological childhood complication.

MATERIAL AND METHODS

This study was conducted on Makassed School children aged 5–18 years. This was a two-step study, the first step was a questionnaire distributed to the children to be answered by their parents. The second step included individually meeting with every child who met the inclusion criteria and his/her parents and physically examining the child.

RESULTS

11,440 questionnaires were distributed to school children aged 5–18 years, to be answered by their parents. Of the 7270 parents who responded back, 6620 reported no enuresis, 90 (1.25%) reported only diurnal enuresis, 107 (1.5%) reported diurnal and nocturnal enuresis, and 453 parents reported their child having nocturnal enuresis only. The data collected was analyzed according to age, sex, area, body mass index (BMI), and the PMQOL-SF score. The prevalence of mono-symptomatic nocturnal enuresis (MNE) in Lebanon was found to be 5.3%. The results showed that the prevalence of MNE is inversely proportional to age. The prevalence of male to female ratio was 1.4:1. As for the prevalence according to different geographic areas, the results have shown that the North had the majority of cases with 7.6% prevalence. Results showed that 82.4% of children had a score more than 50, and only 28% of parents had a score above 50.

DISCUSSION

The prevalence of nocturnal enuresis in Lebanon is lower than that in neighboring countries such as Turkey8 and Saudi Arabia,9 but higher than that in Italy10 and Hong Kong. Our study has managed to show the same results, with a peak in incidence at seven years then dropping back to 0% at the age of 16. Our study has shown a male to female predominance but the male to female ratio was 1.4:1, a value lower than that described in earlier studies. Our study has shown that more than 80% of children were psychologically affected whereas only less than 30% of parents were affected.

CONCLUSION

To our knowledge, this was the first study in Lebanon conducted to determine the prevalence of MNE. The relatively low prevalence rate found may be because of differences in genetic predisposition, psychosocial or environmental conditions, and traditional and cultural backgrounds. No relation was found between obesity and nocturnal enuresis. The psychological impact on children is significant but that on the parents is minimal.

[Classification of enuresis/encopresis according to DSM-5]

Elimination disorders are common in childhood and adolescence. Enuresis is traditionally defined as wetting from the age of 5 years and encopresis as soiling from 4 years onwards - after all organic causes have been excluded. In the past decades, many subtypes of elimination disorders have been identified with different symptoms, etiologies, and specific treatment options. Unfortunately, the DSM-5 criteria did not integrate these new approaches. In contrast, classification systems of the International Children's Incontinence Society (ICCS) for enuresis and urinary incontinence as well as the ROME-III criteria for fecal incontinence offer new and relevant suggestions for both clinical and research purposes.

Long-term followup of children with nocturnal enuresis: increased frequency of nocturia in adulthood

PURPOSE

We investigated the long-term prognosis of a cohort of children with nocturnal enuresis, and identified the prevalence of nocturia and persistent comorbid symptoms.

MATERIALS AND METHODS

A questionnaire was sent to 1,265 patients treated for nocturnal enuresis during childhood at our university hospital. We used a validated tool, the International Consultation on Incontinence Modular Questionnaire on overactive bladder and urinary incontinence, to evaluate the presence of current urological symptoms. Participants were also asked about treatment received for nocturnal enuresis, and their medical files were analyzed.

RESULTS

A total of 516 patients (41%) returned the questionnaire. Mean age was 17 years, and 64% of patients were male. Current urgency, daytime frequency and urinary incontinence were reported by 17%, 8% and 25% of patients, respectively. During the period of nocturnal enuresis up to 60% of patients had concomitant daytime symptoms. Nocturia was reported by 182 participants (35%). Males comprised 56% of patients (101) with nocturia and 69% of patients (230) without nocturia. Prevalence of current daytime symptoms and incontinence was higher in patients with nocturia (p<0.001). Those with nocturia were older at resolution of nocturnal enuresis (p<0.001) and suffered more nonmonosymptomatic nocturnal enuresis (p<0.014).

CONCLUSIONS

About a third of patients experience nocturia, a fourth still report some kind of urinary incontinence, a fifth have regular urgency and a tenth have daytime frequency. Thus, resolution of nocturnal enuresis does not necessarily mean resolution of the underlying pathological condition. Some patients with nocturia who continue to suffer with bothersome symptoms might benefit from continuous treatment for the underlying condition.

Traditional Japanese medicine, Yokukansan, for the treatment of nocturnal enuresis in children

BACKGROUND

The major pathogenic factors involved in nocturnal enuresis are nocturnal polyuria, small bladder capacity and/or detrusor overactivity, and a high arousal threshold. Desmopressin is the first-line therapy for the patients with diuresis-dependent nocturnal enuresis. Yokukansan, a traditional Japanese medicine, has been used in Japan to treat patients with nervousness, insomnia, and children with night terrors and temper tantrums. We experienced the positive effect of Yokukansan in some of the patients who did not respond well to desmopressin therapy.

METHODS

In total, 32 children with monosymptomatic nocturnal enuresis with nocturnal polyuria were treated with oral desmopressin melt tablets, which were approved for clinical use in Japan on 29 May 2012. This treatment was effective for 14 of them. For the rest (n = 18), Yokukansan was introduced in combination with desmopressin.

RESULTS

Yokukansan was effective for 12 out of the 18 cases.

CONCLUSIONS

Yokukansan should be a candidate for the medication of nocturnal enuresis.

Role of Urodynamic Study in Nocturnal Enuresis: Urodynamic Findings and Treatment Outcome Correlation in Children with Pharmacotherapy-resistant Monosymptomatic Nocturnal Enuresis or Severe Non-monosymptomatic Nocturnal Enuresis

OBJECTIVES

This study aimed to determine whether or not a urodynamic study (UDS) is beneficial for management of pediatric nocturnal enuresis (NE), especially in pharmacoresistant monosymptomatic nocturnal enuresis (PRMNE) or severe non-monosymptomatic nocturnal enuresis (NMNE) patients.

METHODS

Children with PRMNE or severe NMNE who underwent a UDS for the process of NE treatment were retrospectively reviewed. The UDS findings of patients and treatment outcomes of subsequent tailored therapies according to the UDS findings were analyzed.

RESULTS

A total of 80 children (50 boys and 30 girls, mean age 8.4 ± 2.2 years), 19 of which were diagnosed with PRMNE and 61 of which were diagnosed with NMNE, were included in the final analysis. Of the 19 PRMNE children, 12 (63.2%) demonstrated abnormal UDS findings. Ten demonstrated detrusor overactivity (DO) with or without decreased cystometric bladder capacity (CBC); the treatment outcomes markedly improved in all of the children after anticholinergics were added to the initial desmopressin therapy. Biofeedback was found to be helpful for two children with detrusor-sphincter dyssynergia. All of the total 61 children with NMNE demonstrated abnormal urodynamic findings of DO with or without decreased CBC, and 42 (68.9%) achieved more than partial response (> 50% decrease in the number of wet nights) when given a combination therapy of anticholinergics and desmopressin.

CONCLUSIONS

The urodynamic findings were helpful for guiding children with PRMNE in the proper choice of further treatment strategies. A routine UDS should not be recommended prior to a first-line combination treatment in children with NMNE.

Lower health related quality of life and psychosocial difficulties in children with monosymptomatic nocturnal enuresis--is snoring a marker of severity?

PURPOSE

Sleep disordered breathing in children is linked to numerous negative psychosocial consequences, including lower health related quality of life, increased behavioral problems and impaired neuropsychological functioning. We examined whether snoring, which is the least severe form of sleep disordered breathing, or health related quality of life could account for the increased rate of psychosocial difficulty in children with monosymptomatic nocturnal enuresis.

MATERIALS AND METHODS

Patients diagnosed with monosymptomatic nocturnal enuresis seen at an outpatient pediatric urology clinic completed measures of health related quality of life (Obstructive Sleep Apnea Syndrome-18-Item Questionnaire), sleep disordered breathing (Pediatric Sleep Questionnaire) and psychosocial difficulty (Pediatric Symptom Checklist). Patients were categorized into 2 groups (snoring vs no snoring) based on the Pediatric Symptom Checklist snoring subscale score.

RESULTS

Included in the study were 62 males and 45 females with a mean ± SD age of 9.09 ± 2.58 years and a mean body mass index of 21.00 ± 6.93 kg/m(2) (range 13 to 49). The sample was evenly split between 56 snorers (52.3%) and 51 nonsnorers (47.7%). Compared to children with monosymptomatic nocturnal enuresis who did not snore, MANCOVA results revealed that patients with monosymptomatic nocturnal enuresis who snored had significantly more externalizing problems and total psychosocial problems, in addition to significantly more impairment in all areas of health related quality of life.

CONCLUSIONS

Snoring in children with monosymptomatic nocturnal enuresis puts them at increased risk for behavioral and psychosocial problems, in addition to impaired health related quality of life. These findings support the need for future studies of the neurological links between sleep disordered breathing and monosymptomatic nocturnal enuresis.

Spina bifida occulta: not to be overlooked in children with nocturnal enuresis

OBJECTIVE

Previous reports have suggested that the incidence of spina bifida occulta in patients with nocturnal enuresis is higher than in the general population. However, the effect of spina bifida occulta on the response to nocturnal enuresis treatment is controversial. The purpose of this study was to investigate the relationship between spina bifida occulta and response to treatment of nocturnal enuresis.

METHODS

Between 2006 and 2009, the records of 160 children with nocturnal enuresis were reviewed. Children with other organic urological disease or symptoms suggestive of spinal dysraphism were excluded. Plain radiography for the kidney-ureter-bladder was carried out before the start of the nocturnal enuresis treatment. Response to treatment of children with and without spina bifida occulta was compared.

RESULTS

Of 160 children, 53 were girls; the mean age was 7.8 ± 2.06 years. The mean duration of treatment was 8.7 ± 9.29 months. Spina bifida occulta was detected in 43 children (26.9%). Spina bifida occulta affected L4 in four children, L5 in 12 children, S1 in 26 children and S2 in one child. There was a significant difference between the spina bifida occulta and non-spina bifida occulta groups in terms of outcome (P=0.002), with a complete response more likely in children without spina bifida occulta (P=0.005). None of the children with primary non-mono symptomatic nocturnal enuresis and spina bifida occulta showed a complete response.

CONCLUSIONS

The presence of spina bifida occulta significantly affects the response to treatment in patients with nocturnal enuresis. Thus, verifying spina bifida occulta in this patient population can facilitate the prediction of the response to nocturnal enuresis treatment.

Non-dipping phenomenon in children with monosymptomatic nocturnal enuresis

PURPOSE

Monosymptomatic nocturnal enuresis is a common disorder seen in childhood, and many factors play a role in its etiopathology to varying degrees. The aim of our study was to investigate the possible association between nocturnal enuresis and 24-h blood pressure profiles of enuretic children.

METHODS

A total of 45 children ranging in age from 6 to 15 years with monosymptomatic nocturnal enuresis and 22 age-matched healthy controls were enrolled in our study. The blood pressure measurement was made at 30-min intervals during a 24-h period via an ambulatory blood pressure measurement device. Both groups underwent medical tests that included a complete blood count, blood biochemistry profile, urinalysis and blood renin-aldosterone levels, and all study subjects received an abdominal ultrasound.

RESULTS

Statistically significant high nocturnal blood pressure levels were observed in our patients with monosymptomatic nocturnal enuresis compared with the control group (p < 0.05). The mean values of the day-to-night difference (dipping) in the systolic and diastolic blood pressure of the patients were significantly lower than those of control group (p < 0.05).

CONCLUSION

Nocturnal enuresis should not only be accepted as a urinary system disorder. Possible systemic causative factors have to be examined, especially in patients that are resistant to first-line therapy. Based on the results of our study, we deduce that one of the factors that plays a role in the pathogenesis of enuresis nocturna is a non-dipping blood pressure profile (the "non-dipping" phenomenon).

Is there any correlation between hypercalciuria and nocturnal enuresis?

Nocturnal enuresis is a common problem among children. Hypercalciuria has been proposed as an important etiology of bedwetting. We investigated the incidence of hypercalciuria among children with nocturnal enuresis and age- and sex-matched healthy controls. In this case–control study 118 children with nocturnal enuresis and 100 age-, sex-, and educational district-matched healthy controls were recruited. Urine samples were obtained from each subject twice: immediately after awakening and 2 hours later at school. Urinary calcium and creatinine levels were measured and the subjects with a urinary calcium/creatinine ratio more than 0.2 were considered as hypercalciuric. Serum Ca, P, Na, K, and PTH levels were measured for all hypercalciuric subjects. The mean urine calcium to creatinine ratio in the second urine sample was 0.070±0.06 mg/mg and 0.050±0.046, respectively in the case and control groups (P=0.008). There were 12/118 and 3/100 hypercalciuric subjects in the case and control groups respectively (P=0.032). The serum Ca, P, Na, K, and PTH levels were in normal range in all hypercalciuric subjects. In our study there was a significant difference in the frequency of hypercalciuria among children with nocturnal enuresis and healthy controls, so we can suggest adding the measurement of urine electrolytes especially the calcium level in patients with nocturnal enuresis.

Association between primary nocturnal enuresis and habitual snoring in children with obstructive sleep apnoea-hypopnoea syndrome

INTRODUCTION

Nocturnal enuresis (NE) and obstructive sleep apnoea-hypopnoea syndrome (OSAHS) are common problems during childhood, and population studies have reported a significant correlation between them. This study aimed to assess whether habitual snoring, mouth breathing and daytime sleepiness are associated with increased incidence of NE in children with OSAHS.

MATERIAL AND METHODS

Polysomnography was performed in 42 children (66.7% males), 3.5-14.5 years old, who were evaluated for sleep-disordered breathing (SDB).

RESULTS

Fourteen out of 42 children (33.3%) presented mild, 16 out of 42 (38.1%) moderate and 12 out of 42 (28.6%) severe degree of OSAHS. Apnea hypopnea index (AHI) ranged between 1.30-94.20 (10.54 ±15.67) events per hour of sleep. Nocturnal enuresis was reported in 7/42 (16.7%) of them. The main observed symptoms were snoring (90.5%), restless sleep (81%), mouth breathing (71.4%), nasal congestion (76.2%), and difficulty in arousal (52.4%). A statistically significant association was found between NE and mouth breathing (p = 0.014) or nasal congestion (p = 0.005). Children with OSAHS and NE had a higher arousal index (8.14 ±8.05) compared with OSAHS children without NE (4.61 ±7.95) (p = 0.19, z = -1.28). Snorers had higher levels of AHI (11.02 ±16.37) compared with non-snorers (6.05 ±4.81) (p = 0.33, z = -0.96), and habitually snorers (23/42, 54.76%) were at greater risk of having NE (4/23) than were non-snorers (0/4, p = 0.36). However, the prevalence of enuresis was not related to the severity of OSAHS, expressed as AHI (p = 0.70).

CONCLUSIONS

Mouth breathing, nasal congestion and high threshold of arousal during sleep should be more carefully evaluated in cases of children with NE who do not respond to standard treatment and present SDB.
