Attention deficit and hyperactivity disorder and nocturnal enuresis co-occurrence in the pediatric population: a systematic review and meta-analysis

Clinical phenotyping of children with nocturnal enuresis: A key classification to improve the approach

INTRODUCTION

The literature shows that nocturnal enuresis is not an isolated phenomenon of urinary loss during sleep, but encompasses a set of systemic clinical manifestations that significantly influence children's quality of life and development. However, the understanding of the clinical and physiological relationship of these systemic manifestations remains a clinical challenge. The recognition of these manifestations and their subsequent categorisation, may provide better insights into integrated clinical manifestations, facilitating the understanding of pathophysiological mechanisms, and promote increased assertiveness in the assessment and the selection of appropriate therapies.

OBJECTIVE

The aim of this study is to develop a phenotyping model for children with nocturnal enuresis based on evidence.

METHODS

This study presents a clinical phenotyping model for children with nocturnal enuresis based on an analytical and methodological review of the literature, about nocturnal enuresis and its associated clinical manifestations. There was a bibliometric analysis carried out to better analyse outcomes. After reading and analysing the literature, the clinical manifestations were categorised into domains and submitted to the validation of an expert committee with extensive experience in their specific area of expertise. A visual representation of the categorised model was developed to make the phenotyping concept easily understandable to all professionals.

RESULTS

The clinical manifestations related to nocturnal enuresis have been categorised according to frequency and relation found in the literature and validation by an expert committee and the development of the phenotyping model for children with nocturnal enuresis was completed.

CONCLUSION

The present study developed an evidence-based phenotyping model for children with nocturnal enuresis.

Translation, cross-cultural adaptation and validation of the Short Screening Instrument for Psychological Problems in Enuresis for use in Brazil (SSIPPE-Br)

OBJECTIVE

Enuresis is associated with attentional and emotional comorbidities in 20 to 30 % of cases. The Short Screening Instrument for Psychological Problems in Enuresis (SSIPPE) is a questionnaire that allows the initial screening of these comorbidities. This study aimed to translate, culturally adapt, and validate the SSIPPE for Brazilian children and adolescents (SSIPPE-Br).

METHODS

Six steps were performed for translation and cross-cultural adaptation: translation, synthesis of translations, back-translation, preparation of the pre-final version of the translated instrument, test of comprehensibility of the pre-final version of the tool, and elaboration of the instrument cross-culturally adapted for Brazil, named 13-itens version SSIPPE-Br. To validate the SSIPPE-Br, a cross-sectional study was carried out, in which the validated Brazilian version of the Child and Adolescent Behavior Inventory (CABI) was used.

RESULTS

Validation was performed on 127 children and adolescents with a mean age of 9.7 ± 2.8 years, 48 % male. The reliability was estimated using Cronbach's alpha, ranging from 0.86 to 0.89, indicating good internal consistency. The factorial analysis had a good agreement adjustment (KMO 0.755, Bartlett's test < 0.001) and explained 70.5 % of the data variability. In the reproducibility analysis, the Kappa coefficient ranged from 0.94 to 1, which can be considered almost perfect. A highly significant (p-value < 0.001) and direct correlation existed between the three SSIPPE-Br domains and all evaluated CABI domains.

CONCLUSION

The SSIPPE-Br is a valid and reliable tool for emotional problems screening and ADHD symptoms in children and adolescents with enuresis whose first language is Brazilian Portuguese.

A systematic meta-review of systematic reviews on attention deficit hyperactivity disorder

BACKGROUND

There are now hundreds of systematic reviews on attention deficit hyperactivity disorder (ADHD) of variable quality. To help navigate this literature, we have reviewed systematic reviews on any topic on ADHD.

METHODS

We searched MEDLINE, PubMed, PsycINFO, Cochrane Library, and Web of Science and performed quality assessment according to the Joanna Briggs Institute Manual for Evidence Synthesis. A total of 231 systematic reviews and meta-analyses met the eligibility criteria.

RESULTS

The prevalence of ADHD was 7.2% for children and adolescents and 2.5% for adults, though with major uncertainty due to methodological variation in the existing literature. There is evidence for both biological and social risk factors for ADHD, but this evidence is mostly correlational rather than causal due to confounding and reverse causality. There is strong evidence for the efficacy of pharmacological treatment on symptom reduction in the short-term, particularly for stimulants. However, there is limited evidence for the efficacy of pharmacotherapy in mitigating adverse life trajectories such as educational attainment, employment, substance abuse, injuries, suicides, crime, and comorbid mental and somatic conditions. Pharmacotherapy is linked with side effects like disturbed sleep, reduced appetite, and increased blood pressure, but less is known about potential adverse effects after long-term use. Evidence of the efficacy of nonpharmacological treatments is mixed.

CONCLUSIONS

Despite hundreds of systematic reviews on ADHD, key questions are still unanswered. Evidence gaps remain as to a more accurate prevalence of ADHD, whether documented risk factors are causal, the efficacy of nonpharmacological treatments on any outcomes, and pharmacotherapy in mitigating the adverse outcomes associated with ADHD.

The Prevalence of Nocturnal Enuresis in Bangkok, Thailand: A Descriptive and Questionnaire Survey of 5 to 15 Year-Old School Students

Objectives. Nocturnal enuresis (NE) is a common problem among school-aged children. Nonetheless, further information on NE prevalence in Thailand is needed. The prevalence of NE and factors associated with it were investigated. Methods. A descriptive study was conducted in schools in Bangkok, Thailand, among children aged 5 to 15 years, using a questionnaire survey between November 2018 and July 2019. Results. The prevalence of primary monosymptomatic, primary nonmonosymptomatic, and secondary NEs was 9.7%, 11.6%, and 8.2%, respectively. Primary NE was associated with a family history of NE (OR = 4.05, P < .001), drinking within 2 hours before bedtime (OR = 1.77, P = .01), and deep sleep (OR = 1.62, P = .001). Conclusion. Primary NE was prevalent in this setting, and the most related factor was a family history of NE. Parents should be aware of NE in their children, especially if a child has a linked factor.

Functional urination or defecation disorders may be warning signs of attention-deficit/hyperactivity disorder among children in rural China

BACKGROUND

This study was designed to investigate the prevalence of attention-deficit/hyperactivity disorder (ADHD) and its association with functional urination and defecation disorders among children in rural China.

METHODS

A cross-sectional study was conducted with children aged 6-18 in rural schools in southwest China using a survey questionnaire. The Swanson, Nolan, and Pelham Questionnaire-IV (SNAP-IV) was used to measure ADHD symptoms, and standardized questions about urination and defecation were used to measure lower urinary tract symptoms (LUTS) and functional defecation disorders (FDDs). The association of ADHD with LUTS and FDDs was analyzed by matched logistic regression after propensity score matching was performed to minimize the influence of potential confounders, including demographic characteristics.

RESULTS

A total of 17,279 participants were included in the analyses. The prevalence of ADHD was 2 % mainly among boys before age 12, after which it showed a decreasing trend with age, resulting in a concomitant reduction in gender differences. The risk of ADHD was positively associated with the presence of enuresis, holding maneuvers, intermittency, and encopresis, with encopresis having the strongest association (P = 0.001). The presence of holding maneuvers, intermittency, excessive volitional stool retention, and encopresis were associated with a higher risk of ADHD at 6-15 years-old, with intermittency exhibiting an increasingly positive association with ADHD risk across ages 6-15.

CONCLUSIONS

ADHD was associated with LUTS and FDDs, which highlights that functional urination and/or defecation disorders could serve as warning signs for ADHD that should trigger screening, especially in relatively backward regions with little ADHD awareness.

Non-mental diseases associated with ADHD across the lifespan: Fidgety Philipp and Pippi Longstocking at risk of multimorbidity?

Several non-mental diseases seem to be associated with an increased risk of ADHD and ADHD seems to be associated with increased risk for non-mental diseases. The underlying trajectories leading to such brain-body co-occurrences are often unclear - are there direct causal relationships from one disorder to the other, or does the sharing of genetic and/or environmental risk factors lead to their occurring together more frequently or both? Our goal with this narrative review was to provide a conceptual synthesis of the associations between ADHD and non-mental disease across the lifespan. We discuss potential shared pathologic mechanisms, genetic background and treatments in co-occurring diseases. For those co-occurrences for which published studies with sufficient sample sizes exist, meta-analyses have been published by others and we discuss those in detail. We conclude that non-mental diseases are common in ADHD and vice versa and add to the disease burden of the patient across the lifespan. Insufficient attention to such co-occurring conditions may result in missed diagnoses and suboptimal treatment in the affected individuals.
