Project description:Nocturnal enuresis (NE) is a common problem among 10% school-aged children. The etiologies underlying childhood NE is complex and not fully understood nowadays. Nevertheless, increasing evidence suggests a potential link between neurobehavioral disorders and enuresis in children. In this study, we aimed to explore novel metabolomic insights into the pathophysiology of NE and also, its association with pediatric psychiatric problems. Urine collected from 41 bedwetting children and 27 healthy control children was analyzed by using 1H-nuclear magnetic resonance spectroscopy from August 2017 to December 2018. At regular follow-up, there were 14 children with refractory NE having a diagnosis of attention deficient hyperactivity disorder (ADHD) or anxiety. Eventually, we identified eight significantly differential urinary metabolites and particularly increased urinary excretion of betaine, creatine and guanidinoacetate linked to glycine, serine and threonine metabolism were associated with a comorbidity of neurobehavioral disorders in refractory bedwetting children. Notably, based on physiological functions of betaine acting as a renal osmolyte and methyl group donor, we speculated its potential role in modulation of renal and/or central circadian clock systems, becoming a useful urinary metabolic marker in diagnosis of treatment-resistant NE in children affected by these two disorders.
Project description:Childhood obesity increases the risk of obstructive sleep apnea syndrome, type 2 diabetes mellitus, cardiovascular abnormalities, and psychological and behavioral disorders. But it is unclear whether obesity is associated with childhood nocturnal enuresis (NE). This study aimed to assess the relationship between childhood obesity and NE in a nationally representative large sample in China. Subjects were enrolled from Urumqi, Chengdu, Xi'an, Hohhot, Wuhan, Canton, Shanghai, and Harbin cities in China in November and December 2005. The survey included 20,987 children aged 5-12 years and they and their caregivers completed questionnaires. Height and weight were measured by school teachers trained in healthcare. According to the WHO child growth standards, obesity was defined as a body mass index >95th percentile of peers with the same age and gender. NE was defined as bed wetting for more than twice a week for 3 consecutive months. Demographic variables were compared among different groups. The prevalence of obesity, asthma, attention-deficit/hyperactivity disorder (ADHD), depressive moods, and snoring were different between the NE and without-NE groups (P < 0.05). The raw odds ratio (OR) for NE and obesity was 1.36 (95%CI = 1.07-1.74; P = 0.013) and the adjusted OR was 1.42 (95%CI = 1.11-1.82; P = 0.005) in the multivariable analysis. When adjusting for co-occurring conditions, the results showed that asthma did not affect the risk of NE (OR = 1.42, 95%CI = 1.11-1.82; P = 0.005), but ADHD (OR = 1.41; 95%CI = 1.10-1.81; P = 0.006) and depressive moods (OR = 1.34; 95%CI = 1.07-1.76; P = 0.012) slightly weakens the association between NE in children and obesity, while snoring weakens the association between obesity and NE and the risk became non-significant (OR = 1.21; 95%CI = 0.94-1.56; P = 0.138). In conclusion, obese children were at a higher risk of incurring NE compared to non-obese children. This association was weaker in children who either snored, had ADHD, or had depressive mood.
Project description:Primary monosymptomatic nocturnal enuresis (PMNE) is a common developmental disorder in children. Previous literature has suggested that PMNE not only is a micturition disorder but also is characterized by cerebral structure abnormalities and dysfunction. However, the biological mechanisms underlying the disease are not thoroughly understood. Graph theoretical analysis has provided a unique tool to reveal the intrinsic attributes of the connectivity patterns of a complex network from a global perspective. Resting-state fMRI was performed in 20 children with PMNE and 20 healthy controls. Brain networks were constructed by computing Pearson's correlations for blood oxygenation level-dependent temporal fluctuations among the 2 groups, followed by graph-based network analyses. The functional brain networks in the PMNE patients were characterized by a significantly lower clustering coefficient, global and local efficiency, and higher characteristic path length compared with controls. PMNE patients also showed a reduced nodal efficiency in the bilateral calcarine sulcus, bilateral cuneus, bilateral lingual gyri, and right superior temporal gyrus. Our findings suggest that PMNE includes brain network alterations that may affect global communication and integration.
Project description:Ehlers-Danlos syndrome (EDS), hypermobility type, is probably the most common EDS type, as well as the most common heritable connective tissue disorder. Bladder dysfunction is a rare clinical manifestation of EDS and manifests itself as primary nocturnal enuresis. We present a 10-year-old boy referred to the paediatrics nephrology consultation due to primary nocturnal enuresis and day time symptoms of urinary urgency. During the appointment, a tendency to joint hypermobility was noted. On evaluation the skin was hyperextensible and the Beighton score was positive. The genetic testing revealed a variant of the COL5A1 gene not yet described in the literature.
Project description: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. TRIAL REGISTRATION:The trial is registered at ClinicalTrials.gov with a ClinicalTrials.gov Identifier: NCT02538302. FUNDING:The funder of this research is Hormozgan University of Medical Sciences.
Project description:ObjectiveTo investigate whether rapid maxillary expansion (RME) is a useful treatment method for nocturnal enuresis (NE) and whether the treatment effect is due to placebo. The study also aimed to identify prognostic variables in patients responding to treatment.Materials and methodsThirty-eight children with therapy-resistant NE were recruited and randomized into two groups: the intervention group or placebo group. Both groups were treated with RME, but the placebo group received treatment with a sham appliance for 2 weeks before having the actual treatment. A medical history focused on micturition habits, previous treatment, heredity, and sleep disorders was taken. Daytime voided volumes and nocturnal urine production during wet nights were recorded before the intervention.ResultsOf the 38 patients recruited, two dropped out as one patient was unable to take dental impressions and one refused to have the appliance fitted. There was a statistically significant reduction of wet nights after the RME treatment (P < .001). No significant reduction was found after the placebo treatment (P < .40). Eleven patients (35%) had their enuresis frequency reduced by >50%. Large voiding volume and a wide maxilla at baseline had a strong association with positive treatment outcome.ConclusionsRME has a modest effect on children with therapy-resistant NE. The treatment outcome does not seem to be due to a placebo effect of the appliance. A wide maxillary width and large voiding volume at baseline seem to be positive predictors regarding response to treatment.
Project description:Several lines of evidence indicate that multiple abnormalities of gray matter are related to the pathogenesis of primary nocturnal enuresis (PNE); however, few studies have been conducted with respect to abnormalities in white matter (WM) of children with PNE. The present work investigated the microstructure of WM in children with PNE using a neurite orientation dispersion and density imaging (NODDI) method. NODDI data were obtained from 29 children with PNE (age = 9.8 ± 1.2 years, 59% males) and 34 healthy controls (age = 10.3 ± 1.6 years, 56% males) in this study. Multi-b-value diffusion-weighted imaging data were acquired with a 3 T MR system, and the orientation dispersion index (ODI) and neurite density index (NDI) maps were calculated. Tract-Based Spatial Statistics analyses of WM tracts were performed with ODI and NDI maps in children with PNE and controls. Children with PNE had lower ODIs in WM fiber tracts of the bilateral superior longitudinal fasciculus (SLF) and higher ODIs in the bilateral internal capsule (IC) and right anterior thalamic radiation (ATR) than controls. PNE children also had lower NDIs in the bilateral IC and the cingulum and higher NDIs in the bilateral SLF. These changes in NODDI indices, which indicated abnormal neural maturation of the WM microstructures, may be related to abnormal sleep and enuresis in children with PNE.
Project description:ObjectiveTo determine the prevalence of paediatric nocturnal enuresis in Santo Domingo, Dominican Republic.DesignA cross-sectional study was performed using a pretested questionnaire.SettingThree different schools in Santo Domingo, Dominican Republic.Participants700 children aged 5-11 years attending one of the different schools in Santo Domingo, Dominican Republic.InterventionThe study was carried out from November 2017 to December 2017.Main outcome measuresPrevalence of nocturnal enuresis.Results700 questionnaires were sent to be filled and 682 were returned. 655 fully filled questionnaires met the requirements of the study. 183 children were identified with nocturnal enuresis among which 88 were boys and 95 were girls. Only 11% of children with enuresis sought medical help. The prevalence of nocturnal enuresis was 27.9%. No statistical significance was found between gender, order in the family, constipation and breast feeding (p>0.05). Age, deep sleep and family history of enuresis were strongly associated with nocturnal enuresis.ConclusionsThe prevalence of nocturnal enuresis in Santo Domingo was found to be 27.9% and it was higher compared with some Asian countries but lower than Morocco and Jamaica. Only 11% of children with enuresis sought medical help. Nocturnal enuresis is an important problem in the paediatric population of Santo Domingo, but very few children receive treatment due to the financial costs of healthcare in the Dominican Republic.
Project description:Objectives: Nocturnal enuresis (NE) is a common pediatric condition, and desmopressin (dDAVP) is a first-line therapy for NE. The standard initial dosage of dDAVP is 0. 2 mg/day, and most guidelines recommend that the dose should be increased at 0.2 mg increments until dryness is achieved or to the maximal recommended dose. However, previous evidence has shown that this strategy seems insufficient to further improve efficacy and results in unnecessarily high doses for some patients. Our study aimed to assess the efficacy of our modified dDAVP treatment regimen in children with MNE in China and evaluate predictive factors associated with the dDAVP response. Methods: All MNE patients at the Department of Nephrology at Children's Hospital of Fudan University from January to December 2019 were prospectively and consecutively enrolled. dDAVP treatment comprised a dose titration period and a 3-month maintenance period. The efficacy of dDAVP was assessed according to the latest International Children's Continence Society criteria at the end of the study. Predictive factors were evaluated by logistic regression analysis. Results: Overall, 322 MNE patients were enrolled in our study, and 225 (69.9%) completed the study. The intention to treat analysis showed that the overall dDAVP response rate was 69.9%: among these patients 32.3% were complete responders, and 37.6% were partial responders. At the end of the study, 194/225 (86.2%) patients received a final dose of 0.2 mg, 24/225 (10.7%) patients received a final dose of 0.3 mg, and 7/225 (3.1%) patients received a final dose of 0.4 mg. Multivariate analysis showed that patients requiring lower doses to achieve responses were significantly more likely to experience complete response during the maintenance period [odds ratio (OR)=9.683; 95% confidence interval (CI), 2.770-33.846]. Conclusions: Our results indicate that the dDAVP treatment regimen provides a comparable efficacy to the international conventional treatment regimen with a lower overall dose. Low-dose responders were likely to achieve a complete response without increasing the dose; in these cases, the maximum dose might not be necessary.
