A retrospective observational study of enuresis, daytime voiding symptoms, and response to medical therapy in children with attention deficit hyperactivity disorder and autism spectrum disorder

Sleep-Related Urologic Dysfunction

This article reports on the epidemiology, prevalence, and physiopathology of sleep-related urinary dysfunction, a new syndromic category proposed by the recently revised ICSD-3-TR classification. Sleep enuresis, whether primary or secondary, monosymptomatic or plurisymptomatic, will be reviewed in terms of risk factors, comorbidity, and diagnostic and therapeutic indications. A definition of nocturia and its impact on patients' health, quality of life, and mortality will follow. Finally, the impact of urge incontinence on various medical and neurologic disorders will be discussed. Special emphasis will be placed on the possible association of this parasomnia with several sleep disorders and poor, fragmented sleep.

Optimising the management of children with concomitant bladder dysfunction and behavioural disorders

Bladder dysfunction and behavioural disorders in children are commonly concomitant; hence, it is difficult to treat each in isolation. Pharmacotherapy is common treatment for behavioural disorders, and these medications may have intended or unintended positive or negative bladder sequelae. This review identifies the literature regarding the effects of behavioural pharmacotherapy on bladder functioning and possible bladder management strategies in children with concomitant behaviour and bladder disorders to enable clinicians to better manage both conditions. A PROSPERO registered PRISMA-guided review of three major databases was performed. After an initial scoping study revealed significant heterogeneity, a narrative approach was undertaken to discuss the results of all relevant cases relating to children being treated with pharmacotherapy for behaviour disorders and outcomes related to bladder function. Studies were screened to identify those that described effects of commonly prescribed medications in children with behavioural disorders such as stimulants, alpha 2 agonists, tricyclic antidepressants (TCA), serotonin and noradrenergic reuptake inhibitors (SNRI), selective serotonin reuptake inhibitors (SSRI) and antipsychotics, and the findings and implications were summarised. The review identified 46 studies relevant to behavioural pharmacotherapy and bladder function (stimulants (n = 9), alpha 2 agonists (n = 2), TCAs (n = 7), SNRIs (n = 8), SSRIs (n = 8) and antipsychotics (n = 6). Six studies focused specifically on bladder management in children with behavioural disorders with concurrent behavioural pharmacotherapy. This review identifies useful factors that may assist clinicians with predicting unintended bladder effects following initiation of behavioural pharmacotherapy to facilitate the best approach to the treatment of bladder dysfunction in children with behavioural disorders. With this evidence, we have provided a useful decision-making algorithm to aide clinicians in the management of these dual pathologies.

Proof-of-Concept of Microwave-Based Bladder State Detection Using Realistic Pelvic Models

Goal: Urinary incontinence (UI) affects a significant proportion of the population and is associated with negative physical and psychological side-effects. Microwave-based technologies may have the potential to monitor bladder volume, providing a proactive, low-cost and non-invasive tool to support individuals with UI. Methods: Studies to date on microwave bladder monitoring have been limited to highly simplified computational and experimental scenarios. In this work, we study the most realistic models to date (both male and female), which incorporate dielectrically and anatomically representative tissues of the pelvic region. Results: We examine the ability of detecting bladder fullness through both reflection and transmission-based parameters and, for the first time, study the effect of urine permittivity. As a proof-of-concept of bladder state detection, we further investigate reconstructing differential radar images of the bladder with two different volumes of urine. Conclusions: The results indicate that there is strong potential for monitoring and detecting the bladder state using microwave measurements.

Systematic review and meta-analysis: relationships between attention-deficit/hyperactivity disorder and urinary symptoms in children

Lower urinary tract symptoms (LUTS), e.g., urinary frequency, pressure, urgency, and overactive bladder syndrome, are commonly reported in children with attention-deficit/hyperactivity disorder (ADHD). Understanding the co-occurrence of these conditions has implications regarding clinical approaches, treatments, and improved quality of life. We conducted a systematic review and meta-analysis to examine the relationships between LUTS and ADHD in children. We searched for articles published between January 1990 and July 2019, in PubMed, CENTRAL, and PsycNet. Two authors independently screened all articles and extracted data. We performed random-effect meta-analyses for ADHD with pooled outcomes for LUTS. We identified 119 relevant articles in the literature and 18 articles fulfilled the inclusion criteria for the systematic review, of which, 5 articles had sufficient data for meta-analysis. Examining ADHD among individuals with LUTS, the odds ratio was 2.99 (95% CI 1.13, 7.88, p < 0.001), compared to controls. In multiple studies, the mean overall score for LUTS, using a standardized measure, was significantly higher in patients with ADHD in comparison to controls, and the severity of ADHD was positively associated with the severity of LUTS. Younger age in children was correlated with a higher LUTS score. Different subtypes of urinary incontinence demonstrated differences in behavioral problems and psychiatric comorbidity. Sex differences in LUTS were not consistent across articles. Our results indicate clinically significant associations between ADHD and LUTS in children. Because LUTS and ADHD are common disorders in children, clinicians should be aware of these associations as they inform optimal assessment and treatment strategies.

Problems with enuresis management-A personal view

Much has happened since the end of the era when enuresis was blamed on the parents or the children themselves. Still, there are large gaps in our knowledge and large parts of modern enuresis management guidelines are (still) not based on firm evidence. In this review I will question the following commonly made assumptions regarding enuresis evaluation and treatment: •It is important to subdivide enuresis according to the presence of daytime symptoms•Voiding charts are crucial in the primary evaluation of the enuretic child•All children with enuresis need to be screened for behavioral or psychiatric issues•Concomittant daytime incontinence needs to be successfully treated before addressing the enuresis•Concomittant constipation needs to be successfully treated before addressing the enuresis•Urotherapy is a first-line treatment against enuresis In this review I will argue that much of what we do with these children is based more on experience and well-meant but poorly supported assumptions than on evidence. Some advice and therapies are probably ineffective whereas for other treatments we lack reliable predictors of treatment response. More research is obviously needed, but awaiting new results enuresis management could be substantially simplified.

Improving continence in children and young people with neurodisability: a systematic review and survey

BACKGROUND

Children and young people with neurodisability often need help to achieve socially acceptable bladder and bowel control. Approaches vary depending on whether or not the impairment results from spinal cord pathology that impairs motor control and sensation of the bladder and bowel. Currently, there is uncertainty about which interventions are effective.

OBJECTIVE

The objective was to summarise the available evidence on and current practice for improving continence in children and young people with neurodisability.

DESIGN

A systematic review of the effectiveness, cost-effectiveness and factors that modify intervention implementation, alongside a cross-sectional, online survey of current practice with health professionals, parent carers, school and care staff and young people with neurodisability.

RESULTS

Twelve databases were searched in the review, resulting in 5756 references; 71 studies (72 papers) were included in the analyses. Most of the evidence was for children with spinal cord pathology, which involved evaluations of pharmacological approaches and surgical techniques, whereas the evidence pertaining to those with non-spinal-cord-related pathology tended to be for behavioural interventions. The methodological quality of studies was rated as being moderate to poor. There were three robust qualitative studies about the experience of continence among children with spinal cord pathology. We found substantial heterogeneity across the interventions that we evaluated in terms of quality, study design and outcomes measured. No economic studies were found. The results were synthesised narratively and reported in text and tables. We did not find any eligible studies evaluating interventions using toilet and clothing adaptations in the review, although the survey highlighted that these types of interventions are frequently used and considered. In total, 949 people responded to the survey: 202 health professionals, 605 parent carers, 122 school and social care staff, and 20 young people. The survey results illustrated the different roles that professionals have in improving continence, highlighting the importance of a multidisciplinary approach to supporting children and young people and their families. Clinicians employ a range of assessments and interventions to improve continence or independent toileting, depending on the needs of the child.

LIMITATIONS

Quantitative studies in the review were not methodologically robust. The survey had a risk of response bias.

CONCLUSIONS

Our research found a dearth of good-quality evidence for many of the interventions currently in use, and no evidence of experiences of implementing interventions for children with non-spinal-cord-related pathology. There was also no evidence of cost-effectiveness of any of the interventions.

FUTURE WORK

There is a need to involve young people and families in the design of high-quality evaluative research for interventions that aim to improve continence. This is especially the case for children with autism and learning disability, who have been neglected in previous evaluative and qualitative research. We recommend better training for health, education and care professionals about toileting, informed by evidence and the lived experiences of children and their families. We recommend a joined-up multidisciplinary and holistic approach to improving continence to maximise independence, dignity and comfort. It is vital that children and young people with neurodisability have early access to regular, integrated assessment of their bladder and bowel health, and are fully supported with appropriate personalised treatment.

Treating enuresis in children with neurodevelopmental disorders using bell and pad alarm

OBJECTIVE

There is a high prevalence of enuresis in children with neurodevelopmental disorders, yet research regarding treatment for this group has been neglected. The efficacy of treatment using bell and pad alarm therapy is not well reported especially in children with neurodevelopmental disorders. This study sought to compare the treatment efficacy of practitioner-assisted bell-and-pad enuresis alarm therapy for children with neurodevelopmental disorders and typically developing children.

STUDY DESIGN

This study utilized the data of Apos et al. (2018), a retrospective medical record audit collected from multiple clinical settings across Australia. A total of 2986 patient records (3659 treatment records) were included. The participants were children aged 5-16 years, who were diagnosed with enuresis. Children with a neurodevelopmental disorder (n = 158) had a clinical diagnosis present in the medical history of attention deficit disorder, autism spectrum disorder, or intellectual disability. Children who indicated any of the following comorbidities were excluded: cerebral palsy, brain injury, malformation of the renal tract, previous bladder or renal surgery, spinal cord malformation, spinal cord trauma or tumor, or a neurodegenerative disorder. Treatment success was defined as ≥ 14 dry nights. Relapse was defined as one symptom recurrence per month post-interruption of treatment, as defined by the International Children's Continence Society definitions.

RESULTS

The success rate for children with neurodevelopmental disorders was 62% and typically developing children was 78%. There was no significant difference between the number of treatments received or relapse rates by those children with a neurodevelopmental disorder and typically developing children. The summary figure shows the percentage of children in each group after their first treatment who were successful (success defined as dry for ≥ 14 days), who succeeded (dry for ≥ 14 days) but then relapsed and those who showed no success. The percentage of children with no NDD who were successfully dry after the first treatment was 78%. Children with ID had success after the first treatment of 59%, the lowest of all groups analyzed.

CONCLUSION

The type of alarm therapy reported in this study is effective for treating enuresis in children with neurodevelopmental disorders.

Neurodevelopmental disorders and incontinence in children and adolescents: Attention-deficit/hyperactivity disorder, autism spectrum disorder, and intellectual disability-A consensus document of the International Children's Continence Society

AIMS

Neurodevelopmental disorders (NDs) are incapacitating disorders, which begin early in life, are mainly caused by genetic and neurobiological factors, and show a tendency to persist. They are associated with higher rates of incontinence in children and adolescents, including nocturnal enuresis, daytime urinary incontinence, fecal incontinence, and constipation. Without diagnosis and treatment, they will interfere with incontinence treatment leading to less favorable outcomes. The aim of this International Children's Continence Society (ICCS) document is to provide an overview of the three most important NDs, that is, attention-deficit/hyperactivity disorder, autism spectrum disorder (ASD), and intellectual disability (ID).

METHODS

This consensus paper was commissioned by the ICCS. A selective, nonsystematic review was performed. Guidelines, reviews, and selected studies were included. The recommendations are consensus-based.

RESULTS

ADHD is the most common ND with special relevance in clinical practice. ASD and ID are less common, but more severe disorders than ADHD. Basic principles of the assessment and treatment of NDs are provided. Incontinence is common among patients with NDs. Specific modifications and practical approaches in the treatment of incontinence in children with NDs are outlined.

CONCLUSIONS

Incontinence in children and adolescents with NDs is common. Effective treatment of incontinence should be adapted and modified to the specific needs of patients with NDs. A multiprofessional approach is recommended.

Effectiveness of standard urotherapy (basic bladder advice) and combination therapies in managing bladder dysfunction in children with treated behavioral disorders: Results of a prospective cohort (DABBED) study

AIMS

We evaluated the efficacy of standard urotherapy and combination therapies in treatment of bladder dysfunction in children with treated behavioral disorders.

METHODS

Prospective study of children (6-16 years) with bladder dysfunction and behavioral disorders was conducted between March 2018-2020. Eligible children were initially offered standard urotherapy and those with no response at 3 months were offered combination therapies. Symptomatic response, changes in Akbal score and PinQ score were reported at 6 months and outcomes were correlated to behavioral diagnoses and medications.

RESULTS

Thirty-nine consecutive children (male = 27, mean age [SD] 10.3 [±2.0] years) were recruited, of whom 29 completed the study (five lost to follow-up, three non-compliant to treatment, two excluded). Thirty-four (87%) children had attention deficit/hyperactivity disorder. Monosymptomatic nocturnal enuresis (n = 11) and non-monosymptomatic enuresis (n = 17) were the commonest diagnoses. Following 3-month review, 14 (38%) children continued to receive standard urotherapy, while 15 (41%) children were transitioned to combination therapy. At 6-month review, complete/partial response was seen in 62% (23/37) and no response in 16% (6/37); with 32% (12/37) responding to standard urotherapy alone. Akbal symptom scores (15.9-11.5; P < 0.01) and PinQ scores (26.0-19.5; P = 0.008) improved significantly at 6-month follow-up. Type of underlying behavioral disorder(s) or medications for behavioral disorder did not influence the outcomes.

CONCLUSION

This study confirms that children with underlying behavioral disorders are able to have a good response to the appropriate therapy for their bladder dysfunction with a third of children responding to standard urotherapy alone.

Empathy Impairment in Individuals With Autism Spectrum Conditions From a Multidimensional Perspective: A Meta-Analysis

Background: Although empathy has always been considered to be impaired in individuals with autism spectrum conditions (ASCs), the relevant findings have been inconsistent. The present meta-analysis aims to determine which empathy components are impaired and how culture, gender, and age moderate such empathy impairment.

Methods: By using “Autism,” “Asperger Syndrome,” “Empathy,” and related Chinese synonyms as keywords, we searched the databases of Weipu, Wanfang, CNKI, Web of Science, Science Direct, SpringerLink, and Elsevier through “subject” and “keyword” searches. We also conducted a manual search according to the references. In total, 51 studies from Eastern and Western countries were included in this meta-analysis, which comprised 144 independent effects, 2,095 individuals with ASCs and 2,869 controls without ASCs. For the retrieved data, Hedge's g was taken as the quantitative measure of effect, and CMA V2.0 software was used for publication bias tests (by using Rosenthal's Classic Failsafe-N and Egger's methods), heterogeneity tests (by using a Q-test, I²-test, and H-test) and a moderating effect test (by using a univariate regression model).

Results: The results showed that the empathy impairment evident in individuals with ASCs is component specific; that is, trait-cognitive empathy, trait-empathic concern, state-cognitive empathy, and state-empathic concern are impaired, whereas state-empathic accuracy remains intact, and trait-empathic accuracy is superior to the trait-empathic accuracy in neurotypical individuals. The univariate regression model showed that gender moderates the impairment of the trait-empathic concern, trait-empathic accuracy, and state-cognitive empathy in autistic individuals and that age moderates the impairment of the trait-cognitive empathy, trait-empathic accuracy, state-empathic concern, and state-empathic accuracy in autistic individuals. However, culture does not moderate any empathy components (trait-cognitive empathy, trait-empathic concern, or state-cognitive empathy) involved in the present meta-analysis.

Conclusions: These findings contribute to ending the controversy over the empathic integrity of individuals with ASCs and shed some light on future research about the empathy impairment of autistic individuals. More specifically, subsequent studies should distinguish specific empathy components and consider the role of gender and age when demonstrating empathy impairment in individuals with ASCs. Moreover, related studies based on Asian collectivist cultural samples and female samples should be further enriched.

The overlooked association between lower urinary tract dysfunction and psychiatric disorders: a short screening test for clinical practice

INTRODUCTION

Lower urinary tract dysfunction (LUTD) often presents with other associated comorbidities such as urinary tract infections, constipation, fecal incontinence, and vesicoureteral reflux. However, the psychiatric conditions that can be associated with LUTD tend to go unnoticed. The evaluation, diagnosis, and treatment of LUTD and psychiatric disorders in children are difficult and time-consuming. Moreover, there is currently no accepted consensus on this subject.

OBJECTIVE

In this study, the authors aimed to investigate the relationship between the subgroups of both LUTD and psychiatric disorders.

STUDY DESIGN

LUTD were divided into 4 groups by using voiding dysfunction symptom score (VDSS), bladder diary, and uroflowmetry/electromyography (UF/EMG) test. A short screening test for psychological problems was used to detect psychiatric disorders accompanying each LUTD group. In terms of psychiatric disorders, the patients were divided into two groups: externalizing and internalizing disorders.

RESULTS

A total of 156 children were diagnosed with LUTD. Seventy-six patients had overactive bladder (OAB), 53 had dysfunctional voiding (DV), 14 had primary bladder neck dysfunction (PBND), and 13 had underactive bladder (UAB). Psychiatric disorder was detected in 46 children (29.4%). Of these, 32 had an externalizing and 14 had an internalizing disorder. In terms of age, externalizing disorders were more common in children aged between 6 and 11 years (87.5%), whereas internalizing disorders were seen equally in both age groups. Among these, attention deficit hyperactivity disorder (ADHD) was the most common psychiatric disorder (16.1%). The LUTD groups with the most frequent psychiatric disorders were UAB (53.8%), PBND (35.7%), and OAB (28.9%).

DISCUSSION

Most of the studies investigating the relationship between the lower urinary tract and psychiatric disorders so far have been concerned with the lower urinary tract symptom (LUTS) (such as nighttime or daytime incontinence) and ADHD. However, the present study was performed according to the LUTD classification, which is primarily based on VDSS, bladder diary, and UF/EMG tests. Furthermore, psychiatric disorders were classified into their subgroups. The results have shown that around a quarter of children with LUTD also had comorbid psychiatric disorders. The relationship between LUTD and psychiatric disorders constitutes a critical point. Identifying this association can contribute to the comprehensive diagnosis and treatment for these patients.

CONCLUSIONS

LUTD and psychiatric disorders can be seen together, and this can be detected by the short screening test for psychological problems. Therefore, the authors think that patients who applied with LUTS should undergo this short test along with the routine urinary system examination and tests.

Physical health in children with neurodevelopmental disorders

With increasing numbers of children being diagnosed with neurodevelopmental disorders (NDDs) attention has been drawn to these children's physical health. We aimed to identify the prevalence of defined physical problems (epilepsy, migraine, asthma, cancer, diabetes, psoriasis, lactose intolerance, celiac disease, diarrhea, constipation, daytime enuresis, encopresis) in a nationwide population of 9- and 12-year-old twins subdivided into those with and without indications of NDDs. Parents of 28,058 twins participated in a well-validated telephone interview regarding their children's mental health and answered questions about their physical problems. The results indicate a high rate of physical problems in children with NDDs, particularly in those with indications of the presence of combinations of several NDDs.

Image-based classification of bladder state using electrical impedance tomography

OBJECTIVE

In this study, we examine the potential of using machine learning classification to determine the bladder state ('not full', 'full') with electrical impedance tomography (EIT) images of the pelvic region. Accurate classification of these states would enable urinary incontinence (UI) monitoring to alert the patient, before involuntary voiding occurs, in a low-cost and discrete manner.

APPROACH

Using both numerical and experimental data, we form datasets that contain diverse observations with varying clinical parameters such as bladder volume, urine conductivity, and the reference used for time-difference imaging. We then classify the bladder state using both pixel-wise and feature extraction-based classification techniques. We employ principal component analysis, wavelets, and image segmentation to help create features.

MAIN RESULTS

The performance was compared across several classifier algorithms. The minimum accuracy was 77.50%. The highest accuracy observed was 100%, and was found by combining principal component analysis and the Gaussian radial based function kernel support vector machine. This combination also offered the best trade-off between classification performance and the costs of training time and memory space. The biggest challenge in bladder state classification is classifying volumes near the separation volume of not full and full, in which choosing the most suitable classifier combination can minimize this error.

SIGNIFICANCE

We performed the first machine learning classification of bladder EIT images, achieving high classification accuracies with both numerical and experimental data. This work highlights the potential of using image-based machine learning with an EIT device to support bladder monitoring for those suffering from UI.

Incontinence in autism spectrum disorder: a systematic review

Autism spectrum disorders (ASD) are defined by persistent deficits in reciprocal social interaction, communication, and language, as well as stereotyped and repetitive behavior. Functional incontinence, as well as ASD are common disorders in childhood. The aim of this systematic review was to give an overview of the co-occurrence of nocturnal enuresis (NE), daytime urinary incontinence (DUI), and fecal incontinence (FI) in ASD, and vice versa, of ASD in children with incontinence. A systematic literature search of the terms "incontinence", "enuresis", and "encopresis" in combination with "autism" or "Asperger" in four databases (Scopus, PubMed, PsycInfo and Web of science) was conducted. All studies that examined incontinence frequencies in samples with ASD, and studies that measured frequencies of ASD diagnoses or symptoms in samples with incontinence were included. Risk of bias and limitations of each study were described. After eligibility assessment, 33 publications were included in the review. The published literature implies a higher prevalence of incontinence in children with ASD compared to typically developing children. Limitations and biases as inappropriate diagnostic criteria for ASD and incontinence, selected samples, or lack of control groups are reported. Associations of incontinence in ASD with psychopathological symptoms were found. Vice versa, ASD symptoms are found in incontinent children, but no study included a non-ASD control sample. Incontinence symptoms are also reported as an adverse effect of medication in ASD. Due to methodological problems and definitional discrepancies in some publications, results have to be interpreted cautiously. Research in ASD and incontinence is scarce. More systematic research including state-of-the-art assessments is needed.

Children with nocturnal enuresis and attention deficit hyperactivity disorder: A separate entity?

INTRODUCTION

There is ongoing debate about whether nocturnal enuresis (NE) is affected by the presence of attention deficit hyperactivity disorder (ADHD) in children. Clarifying this relationship could categorize them as a separate entity, potentially requiring a different management from enuretic children without ADHD.

AIMS

To study whether (1) children with ADHD exhibited greater severity of enuresis and associated voiding symptoms compared with children without ADHD, (2) whether there was a difference in enuretic response to treatment between children with/without ADHD, (3) whether previously prescribed medication for ADHD affected severity of enuresis or voiding symptoms, and response to treatment.

METHODS

Data on all consecutive children seen with primary NE and ADHD and age- and gender-matched children with NE without ADHD over the course of 2 years were extracted from our database. Controls were identified using a random number generator to choose patients within each age/gender group. Changes in Dysfunctional Voiding Scoring System (DVSS) and Bristol scores were assessed before and after treatment for NE using repeated measures ANOVAs. Number of weekly wet nights was compared between the groups before and after the treatment of enuresis. Children with more than a 50% decrease in number of wet nights per week were categorized as responding to treatment.

RESULTS

Compared with controls, ADHD children (N = 95) had significantly more severe voiding symptoms, NE and constipation (Table). No significant differences were found between children on ADHD medication (63.2%) and those who were not on ADHD medication (36.8%) on any of the demographic and pre-treatment clinical parameters. Similar enuretic response rates to behavioral modification alone were seen in both study (13.5%) and control (12.8%) groups (p = 0.73). Response to pharmacological treatment was seen in nine patients with ADHD (42.9%) and in six (20.7%) controls, with pharmacological intervention being significantly more effective than behavioral modification for patients with ADHD (p = 0.012). Additionally, no difference was found between ADHD patients on and off ADHD medication in terms of response to enuresis treatment.

CONCLUSION

In children with primary NE, the presence of ADHD was associated with more severe NE, voiding symptoms and constipation. The severity of voiding symptoms and/or NE was unrelated to the use of stimulant medication. The response to behavioral modification was comparable in both groups. However, patients with ADHD were significantly more responsive to medication for NE compared with behavioral modification, indicating a possible benefit for earlier pharmacological treatment for enuresis in this population subgroup.

Extracting autism spectrum disorder data from the electronic health record

BACKGROUND

Little is known about the health care utilization patterns of individuals with pediatric autism spectrum disorder (ASD).

OBJECTIVES

Electronic health record (EHR) data provide an opportunity to study medical utilization and track outcomes among children with ASD.  Methods: Using a pediatric, tertiary, academic hospital's Epic EHR, search queries were built to identify individuals aged 2-18 with International Classification of Diseases, Ninth Revision (ICD-9) codes, 299.00, 299.10, and 299.80 in their records. Codes were entered in the EHR using four different workflows: (1) during an ambulatory visit, (2) abstracted by Health Information Management (HIM) for an encounter, (3) recorded on the patient problem list, or (4) added as a chief complaint during an Emergency Department visit. Once individuals were identified, demographics, scheduling, procedures, and prescribed medications were extracted for all patient-related encounters for the period October 2010 through September 2012.

RESULTS

There were 100,000 encounters for more than 4,800 unique individuals. Individuals were most frequently identified with an HIM abstracted code (82.6%) and least likely to be identified by a chief complaint (45.8%). Categorical frequency for reported race (2 = 816.5, p < 0.001); payor type (2 = 354.1, p < 0.001); encounter type (2 = 1497.0, p < 0.001); and department (2 = 3722.8, p < 0.001) differed by search query. Challenges encountered included, locating available discrete data elements and missing data.

CONCLUSIONS

This study identifies challenges inherent in designing inclusive algorithms for identifying individuals with ASD and demonstrates the utility of employing multiple extractions to improve the completeness and quality of EHR data when conducting research.

Rationale and protocol for using a smartphone application to study autism spectrum disorders: SMARTAUTISM

INTRODUCTION

Longitudinal studies on the evolution of autism spectrum disorder (ASD) symptoms are limited and have primarily used repeated measurements performed several months apart. However, measurements of changes in everyday life should more closely reflect the 'real life' of the patient and his or her family. We propose to study the child's ASD symptoms and their effect on the quality of life, psychological status and anxiety of the child's parents over a 6-month period using SMARTAUTISM, a smartphone application.

METHOD AND ANALYSIS

This is a prospective, longitudinal, exploratory, open study with a 6-month follow-up period. Data will be recorded longitudinally over multiple weeks under natural conditions. The factors affecting the quality of life and anxiety of parents of children with ASD and the children's functional symptoms will be examined, and the feasibility of using a smartphone application designed for parents of ASD patients will be assessed.

PRIMARY OBJECTIVE

Explore the evolution of a child's behaviour over 6 months and the (psychological and social) effects of these changes on the family.

SECONDARY OBJECTIVE

Assess the feasibility of our application by examining the filling rate and application usage by parents for 6 months. 100 families containing 1 child diagnosed with ASD will be included. At baseline, sociodemographic, psychiatric and medical data will be recorded. The correlations of the general epidemiological variables (primary outcome measure) will be evaluated via multivariate analysis. The application filling rate (relative to the ideal filling rate) will be used to assess the feasibility of the application (secondary outcome measure).

ETHICS AND DISSEMINATION

The SMARTAUTISM study has the approval of the local ethics committee, and data security will be ensured via the use of encryption and a secure medical server. The use of this application will be proposed at autism resource centres across France.

Incontinence and psychological problems in children: a common central nervous pathway?

Nocturnal enuresis is caused by a mismatch between the nocturnal bladder capacity and the nocturnal diuresis rate, in the presence of a deficient arousability in the majority of patients, according to the pediatric and urologic literature. Psychiatric and psychologic literature are still concentrating on the potential role of psychological factors and central nervous mechanisms in the pathogenesis, as is reflected in the DMS-5 criteria. However, research has clearly shown several important comorbidities between neuropsychological dysfunctions and nocturnal enuresis. Due to the increased comorbidity of (neuro)psychological problems, sleep problems, circadian rhythms, and enuresis, the question arises as to whether there is a possible common central pathway in the pathogenesis. It is likely that the coexistence of these problems can be attributed to a common central nervous system involvement. The specific role of the central nervous system remains unclear, but several pathways are possible. The high comorbidity between enuresis, sleep, and (neuro)psychological functioning is probably attributable to a common pathogenetic pathway, emphasizing the importance of a multidisciplinary focus in screening and treatment in children with nocturnal enuresis.

Incontinence in children with autism spectrum disorder

INTRODUCTION

Autism spectrum disorder (ASD) and incontinence (nocturnal enuresis (NE), daytime urinary incontinence (DUI), fecal incontinence (FI)) are relevant disorders in childhood. In general, children with special needs such as intellectual disability (ID) or ASD are more often affected by incontinence than typically developing children.

OBJECTIVE

In the few studies conducted on children with ASD, gastrointestinal (GI) symptoms have received more attention than NE, DUI and lower urinary tract symptoms (LUTS). The aim of the present study was to assess the prevalence of incontinence, LUTS and psychological symptoms/disorders in children with ASD compared to controls.

STUDY DESIGN

Forty children with ASD (12 children with infantile or childhood autism, 15 with atypical autism and 13 with Asperger's syndrome) (mean age 11.3 years) and 43 age-matched control children (mean age 10.7 years) were assessed. A questionnaire referring to incontinence and the International Consultation on Incontinence Questionnaire-Pediatric LUTS (ICIQ-CLUTS) were administered. Child psychopathology was assessed with the Child Behavior Checklist (CBCL/4-18). Child psychiatric ICD-10 diagnoses were based on a structured psychiatric interview (Kinder-DIPS).

RESULTS

Children with ASD showed increased rates of NE (30.0% vs 0%) and DUI (25.0% vs 4.7%) compared to controls. Among children with ASD, daytime bladder control (≥5 years of age: 20.5% vs 0%) and bowel control (≥4 years of age: 42.5% vs 7.5%) were delayed compared to controls. Children with ASD had a higher LUTS score. Additionally, children with ASD were more often affected by psychological symptoms and disorders. Rates of clinically relevant externalizing symptoms (32.5% vs 0%), internalizing symptoms (67.5% vs 9.3%) and total problem score (70.0% vs 2.1%) were higher in children with ASD than the controls (see table). Children with ASD had more ICD-10 diagnoses than the controls (47.5% vs 4.7%).

DISCUSSION

The present study showed that children with ASD are more at risk of DUI and NE than healthy controls. In addition, children with ASD had more LUTS, especially urgency and postponement, and they needed a longer time to become dry and continent. Additionally, according to the parental CBCL questionnaire, children with ASD showed higher rates of clinically relevant psychological symptoms (externalizing and internalizing symptoms), and according to the psychiatric interview, they had higher rates of comorbid psychological disorders.

CONCLUSION

Autism spectrum disorder is an incapacitating disorder with significant impairment in social functioning. In most cases, psychological symptoms and disorders co-occur. Additionally, children with ASD are at a greater risk of being affected by different forms of incontinence and LUTS. Therefore, screening for incontinence and, if indicated, treatment of these disorders is recommended.

Incontinence in children with treated attention-deficit/hyperactivity disorder

INTRODUCTION

Attention-deficit/hyperactivity disorder (ADHD) and incontinence (nocturnal enuresis, daytime urinary incontinence and fecal incontinence) are common disorders in childhood. Both disorders are strongly associated with each other.

OBJECTIVE

ADHD can affect compliance to incontinence therapy in a negative way; it can also affect outcome. The aim of the present study was to assess the prevalence of incontinence, age of bladder and bowel control, and psychological symptoms in children having treatment for ADHD compared to a control group.

STUDY DESIGN

Forty children having treatment for ADHD (75% boys, mean age 11.4 years) and 43 matched controls (60.5% boys, mean age 10.7 years) were assessed. Their parents filled out questionnaires to assess: child psychopathology (Child Behavior Checklist), incontinence (Parental Questionnaire: Enuresis/Urinary Incontinence; Encopresis Questionnaire - Screening Version) and symptoms of the lower urinary tract (International-Consultation-on-Incontinence-Questionnaire - Pediatric Lower Urinary Tract Symptoms). The ICD-10 diagnoses and children's IQ were measured by standardized instruments (Kinder-DIPS, Coloured Progressive Matrices/Standard Progressive Matrices).

RESULTS

Rates of incontinence in the ADHD group (5% nocturnal enuresis, 5% daytime urinary incontinence, 2.5% fecal incontinence) did not differ significantly from incontinence rates in the control group (4.7% daytime urinary incontinence). More children in the ADHD group had Child Behavior Checklist scores in the clinical range. Further ICD-10 disorders were present in eight children with ADHD and in one control child. More children with ADHD had delayed daytime and nighttime bladder control, as well as delayed bowel control, than the controls.

DISCUSSION

The present study showed that if children are treated for their ADHD, according to standard practice guidelines, incontinence rates are similar to those without ADHD. More children with ADHD reached continence at a later age than the controls, which could be an indicator of maturational deficits in the central nervous system. Additionally, children with ADHD showed higher rates of clinically relevant psychological symptoms.

CONCLUSION

This study provides further information of the association between ADHD and incontinence. Treatment of ADHD may be associated with positive effects on incontinence outcomes. Therefore, children with ADHD should always be screened for incontinence problems and children with incontinence problems should also be screened for ADHD if symptoms of hyperactivity, inattention and/or impulsivity are also present.

Comorbidity of ADHD and incontinence in children

ADHD and incontinence are common childhood disorders which co-occur at much higher rates than expected by chance. The aim of this review was to provide an overview both of the comorbidity of nocturnal enuresis (NE), daytime urinary incontinence (DUI) and faecal incontinence (FI) in children with ADHD; and, vice versa, of the co-occurrence of ADHD in children with NE, DUI and FI. Most clinical studies have focussed on the association of ADHD and NE. Population-based studies have shown that children with DUI have an even greater risk for ADHD than those with NE. While children with FI have the highest overall comorbidity rates of psychological disorders, these are heterogeneous with a wide range of internalising and externalising disorders--not necessarily of ADHD. Genetic studies indicate that ADHD and NE, DUI and FI do not share the same genetic basis. The comorbidity is conferred by non-genetic factors. Possible aetiological and pathogenetic links between ADHD and incontinence are provided by neurophysiological, imaging and pharmacological studies. The co-occurrence has clinical implications: children with ADHD and NE, DUI and FI are more difficult to treat, show lower compliance and have less favourable treatment outcomes for incontinence. Therefore, both groups of disorders have to be assessed and treated specifically.

The medical care of children with autism

The prevalence of autism spectrum disorder (ASD) has increased considerably in the past decades. The primary care paediatrician plays an important role not only in the early recognition of ASD but also in its chronic management. Paediatricians need to be comfortable with the global care of children with ASD. The diagnostic assessment of children with ASD comprises the medical investigations to identify associated or underlying medical conditions. The most important associated conditions are seizures, feeding and gastrointestinal problems, sleep disturbances and dental abnormalities. The care of ASD patients is very demanding since along with the purely medical issues there are challenging behavioural and psychiatric conditions that need consideration and professional skills.
