Advances in the management of primary monosymptomatic nocturnal enuresis in children

Eficácia E Custo-Utilidade De Intervenções Para O Tratamento Da Enurese Em Crianças E Adolescentes Sob A Perspectiva Do Sistema Único De Saúde Brasileiro: Effectiveness and Cost-Utility of Interventions for Enuresis Treatment in Children and Adolescents From the Brazilian Single Health System Perspective

OBJECTIVES

This study aimed to estimate the cost-utility of effective interventions for enuresis treatment in children and adolescents and to calculate the incremental cost-utility ratio from the perspective of the Brazilian Unified Health System in a 1-year time horizon.

METHODS

The economic analysis is in 7 stages: (1) survey of evidence of treatments for enuresis, (2) performing the network meta-analysis, (3) estimation of the probability of cure, (4) cost-utility analysis, (5) model sensitivity analysis, (6) analysis of acceptability of interventions by acceptability curve, and (7) monitoring the technological horizon.

RESULTS

The association between desmopressin and oxybutynin is the therapeutic strategy with the highest probability of success in the treatment of enuresis in children and adolescents compared with placebo (relative risk [RR] 2.88; 95% confidence interval [CI] 1.65-5.04), followed by the combination therapy between desmopressin and tolterodine (RR 2.13; 95% CI 1.13-4.02), alarm (RR 1.59; 95% CI 1.14-2.23), and neurostimulation (RR 1.43; 95% CI 1.04-1.96). Combination therapy between desmopressin and tolterodine was the only 1 considered not to be cost-effective. Neurostimulation, alarm therapy, and therapy had the respective incremental cost-utility ratio values: R$5931.68, R$7982.92, and R$29 050.56/quality-adjusted life-years.

CONCLUSION

Among the therapies that are on the borderline of efficiency, the combined therapy between desmopressin and oxybutynin presents the greatest incremental benefit at an incremental cost that is still feasible, given that it does not exceed the reference value of the cost-effectiveness threshold established in Brazil.

Parental Beliefs About the Causes, Treatments, and Medical Assistance for Children With Nocturnal Enuresis in the Eastern Region of the Kingdom of Saudi Arabia

OBJECTIVE

To assess parental beliefs about the causes, treatment, and necessity for medical assistance for children with nocturnal enuresis (NE).

METHOD

A self-administered survey questioned parents' beliefs about NE, including causes and at-home behavioral therapy. We evaluated the association between demographic characteristics and the tendency to seek medical advice for NE.

RESULT

The questionnaire received responses from 1232 individuals, 77.1% of whom were female and 82.9% of whom were 30 years of age or older. Psychological issues (53.5%) and laziness to get up (47.6%) were the most often believed causes of NE. Two frequent at-home behavioral therapies chosen by participants were voiding before bedtime and restricting fluid intake at night (73.4% and 70%, respectively). However, only 6.9% of respondents believe that a bedwetting alarm is an effective treatment. The two most frequently reported reasons for not seeking medical attention were parents' belief that their child will eventually outgrow bedwetting (34.1%) and "parents or children's embarrassment" (21.8%). The chi-squared test was used to evaluate the association between demographic characteristics and seeking medical advice. Participants with a single child were more likely than those with more than three children to take their child to the doctor (61.5% vs. 48.6%, respectively). Also, parents who don't have NE-afflicted children were more open to consider seeking medical advice for NE therapy (if their children developed it in the future) compared to parents who already have children with NE.

CONCLUSION

Parents in the Eastern region of Saudi Arabia hold various misconceptions about the causes and treatment of NE. Only 52.1% of parents would take their child to see a doctor if wetting the bed and only 48.1% of parents were aware of effective treatments for NE. These results emphasize that healthcare practitioners need to provide proper information to raise public awareness of NE.

Evaluation of the association between asthma and non-neurogenic urinary incontinence in children; a case-control study

BACKGROUND

Asthma is the most common chronic disease in children. Asthma can lead to sleep disorders and psychiatric issues, which are often accompanied by urinary incontinence in children. Furthermore, several studies have shown a relationship between allergic diseases and urinary incontinence. This study aims to examine the association between asthma and non-neurogenic urinary incontinence.

MATERIALS AND METHODS

This case-control study included 314 children over three years old referred to Amir Kabir Hospital; 157 with asthma and 157 without asthma. After explaining each urinary disorder in accordace with the International Children's Continence Society's definitions, parents and children were asked about their presence. The disorders included monosymptomatic nocturnal enuresis(MNE), nonmonosymptomatic nocturnal enuresis (NMNE), vaginal reflux (VR), pollakiuria, infrequent voiding, giggle incontinence (GI), and overactive bladder (OAB). The analysis was performed using Stata 16.

RESULTS

The average age of the children was 8.19 ± 3.15 years. Patients with asthma (p = 0.0001) and GI (p = 0.027) had a considerably lower average age than patients without these disorders. Asthma and urinary incontinence, including NMNE, Infrequent voiding, and OAB, were significantly correlated (p = 0.017, 0.013, and 0.0001, respectively). Moreover, the association between MNE and asthma was significant in males (p = 0.047).

CONCLUSION

Due to the relationship between asthma and urinary incontinence, children with asthma must be evaluated for the presence of urinary disorders and, if present, receive the proper treatment in order to improve their quality of life.

Drugs Used in Parasomnia

Parasomnias, especially disorders of arousal during childhood, are often relatively benign and transitory and do not usually require a pharmacologic therapy. A relevant aspect in both nonrapid eye movement and rapid eye movement parasomnia treatment is to prevent sleep-related injuries by maintaining a safe environment. Physicians should always evaluate the possible presence of favoring and precipitating factors (sleep disorders and drugs). A pharmacologic treatment may be indicated in case of frequent, troublesome, or particularly dangerous events. The aim of this article is to review current available evidence on pharmacologic treatment of different forms of parasomnia.

Alarm Therapy in the Treatment of Enuresis in Children: Types and Efficacy Review

Enuresis is defined as bedwetting in children aged five years and older when organic reasons have been ruled out. It can result in substantial psychological repercussions and uncomfortable circumstances for both the child and the family. Medical (desmopressin, tricyclic antidepressants [TCAs]) and behavioral treatment are the basis for the treatment of enuresis. Alarm therapy is considered the first treatment modality of choice for enuresis with almost 50% cure rates are in the long term. Cooperation and compliance from parents and children are the cornerstones of the effectiveness of alarm therapy. Multiple factors, such as technical issues, might slow down the therapeutic response time. The objective of this study is to review the role of alarm therapy in the treatment of enuresis, its types, and its efficacy and to explore the factors that may increase or decrease its efficacy.

New insights in treatment of monosymptomatic enuresis

OBJECTIVE

Nocturnal enuresis (NE) is defined as uncontrollable bed-wetting for at least three consecutive months in children over 5 years. Sleep could be dramatically altered in children with primary nocturnal enuresis (PNE); consequently, this helps to confirm the assumption that PNE appears to modify sleep structure, or it might be the result of an irregular sleep structure itself.

METHOD

This study conducted on 180 patients with monosymptomatic nocturnal enuresis. Their age was ranged from 6 to 18 years, and they were still having nocturnal enuresis episodes. We record two main points: first, if the child is a regular sleeper or not. The second point if the child is a regular bed wetter or not. This work fully compliant with the STROCCS criteria (Agha et al., 2019).

RESULT

A total of 180 children were included (Male 122, 67.8%, Female 58, 32.2%). The mean age was 8.9 (±2.4). This study showed that children aged 7-10 years are significantly more inclined to be reported as specific time bed-wetter's, whereas those aged between 11 and 13 are significantly less likely to wet their bed at a specific time (p = 0.001). Children who tend to sleep more often near a specific time each night are 6.74 times more prone to bed-wet around a particular time during their sleep (p < 0.001).

CONCLUSION

This study can be considered as hypothesis-generating that shed light on the possible correlation between the adherence to sleep at a specific time and its effect on the time of enuresis and the number of bedwetting.

Drugs Used in Parasomnia

Patient education and behavioral management represent the first treatment approaches to the patient with parasomnia, especially in case of disorders of arousal (DOA). A pharmacologic treatment of DOA may be useful when episodes are frequent and persist despite resolution of predisposing factors, are associated with a high risk of injury, or cause significant impairment, such as excessive sleepiness. Approved drugs for DOA are still lacking. The most commonly used medications are benzodiazepines and antidepressants. The pharmacologic treatment of rapid eye movement sleep behavior disorder is symptomatic, and the most commonly used drugs are clonazepam and melatonin.

Experience Of Medical Treatment With Desmopressin And Imipramine In Children With Severe Primary Nocturnal Enuresis In Taiwan

Purpose

The aim of this study was to compare the efficacy and safety of desmopressin and imipramine in the treatment of severe primary nocturnal enuresis (NE) in Taiwan.

Patients and methods

This study was a retrospective chart review study conducted on children with primary monosymptomatic nocturnal enuresis (PMNE) or non-monosymptomatic nocturnal enuresis (PNMNE), referred to and treated by senior physicians in a Changhua medical center in Taiwan. After being screened, these children were treated with either desmopressin (n = 125) or imipramine (n = 71). All participants were treated for at least 3 months and followed afterward for at least 3 more months. The response and relapse rates were measured. Side effects were monitored. Age, gender, and severity of NE were recorded.

Results

After 3 months of treatment, 97 children treated with desmopressin were responsive (77.6%) while 58 children treated with imipramine were responsive (81.7%). Sixty-one children treated with desmopressin (48.8%) and 26 treated with imipramine (36.6%) relapsed during the 3-month post-treatment monitoring. The differences in responsive and relapse rates were not statistically significant. Four children treated with imipramine (5.6%) reported side effects while none was reported for children treated with desmopressin (P < 0.05). Age, gender, and the presence or absence of daytime enuresis did not influence the response rate to either drug (P < 0.05).

Conclusion

Currently, desmopressin is preferred over imipramine for treating NE due to the latter's side effects. Our results demonstrated similar response rates for both drugs, with imipramine demonstrating minimal side effects. While health practitioners should pay attention to its side effects, concerns regarding imipramine toxicity in NE treatment are often overblown. Since imipramine is much cheaper than desmopressin, using imipramine to manage NE can allow health practitioners, especially in Taiwan, to treat the greatest number of children with NE.

Use of propranolol in children with primary nocturnal enuresis

In nocturnal enuresis, motivational therapy, alarm therapy, and drug therapy, such as anticholinergics, imipramine, and sertraline, are the mainstay of treatment. In the present study, we used motivational therapy, oxybutynin, and propranolol in children with primary nocturnal enuresis to determine if propranolol is an effective treatment. Fifty-two children with primary nocturnal enuresis were included in the study. Firstly, motivational therapy was given for 1 month to all patients. Patients who failed the motivational therapy were randomly given oxybutynin or propranolol. The patients were re-evaluated after 1 month of drug therapy. There was not a significant difference between oxybutynin and propranolol groups for initial frequency of nocturnal enuresis ( p > 0.05). Of 52 patients, 28 (53.8%) patients improved by motivational therapy. There were 14 patients in the oxybutynin group. One patient was excluded from the study because facial flushing and mouth drying developed in the first week of oxybutynin therapy. In oxybutynin group, 12 of 13 (92.3%) patients improved. There were 10 patients in the propranolol group. In the propranolol group, while nine (90%) patients did not improve, one patient had significant remission (90%, p < 0.001). No significant adverse reaction was noted during propranolol therapy. There was no significant difference between oxybutynin and propranolol groups for initial frequency of nocturnal enuresis (p > 0.05). A significant difference was found between the groups for the remission of nocturnal enuresis ( p < 0.001). Our findings showed that motivational therapy is the first line treatment in primary nocturnal enuresis, and oxybutynin but not propranolol is effective in patients who failed with the motivational therapy.

Urinary disorders and bladder-bowel dysfunction in children: approaches to diagnosis, treatment and prevention

Pediatric urinary disorders manifested as urinary incontinence, compelling urges to urinate, etc. remain an important problem of contemporary healthcare. In spite of being extensively covered in the literature, urinary disorders, including enuresis, still present a diagnostic challenge to the physicians of primary healthcare facilities. Based on the findings of our retrospective study that revealed discrepancies between referral and final diagnoses of pediatric urinary disorders, we give recommendations to both physicians of primary healthcare facilities and their inpatient care colleagues that will help them to arrive at the correct diagnosis of a urinary disorder or concomitant bladder-bowel dysfunction using the proposed diagnostic algorithm.

The effect of antidiuretic hormone on urine and serum electrolyte levelsin children with primary monosymptomatic nocturnal enuresis

Background/aim: The data concerning the effects of desmopressin on water/electrolyte disturbances of children with primary monosymptomatic nocturnal enuresis (PMNE) are limited. In the present study we aimed to evaluate the effect and tolerability of desmopressin on blood and urine electrolytes and osmolality in PMNE.Materials and methods: Thirty-five children with PMNE between the ages of 5 and 15 participated in the study. Patients collected urine during the daytime and acknowledged the night time fluid restriction before starting to use the desmopressin tablets. The medication was taken orally at least 1 h before bedtime. Blood and urine samples were collected before the introduction of the treatment (day 0) and on the third and seventh days of the administration of desmopressin to determine osmolality and electrolyte levels.Results: Thirty-five patients participated in the study. Twenty-one patients (60%) were male and 14 (40%) were female. The mean age was 9.6 - 2.7 years. There were no significant changes in serum osmolality, urine osmolality, and serum sodium concentration. Mean urine calcium/creatinine ratio was 0.03 - 0.01 mg/mg at the beginning, 0.06 - 0.02 mg/mg on the third day, and 0.04 - 0.01 mg/mg on the seventh day of the study. No significant changes were seen in urine calcium/creatinine ratio before and after treatment.Conclusion: Desmopressin appeared to be a well-tolerated drug and provided a safe and effective treatment for children who were following fluid intake restriction for PMNE.

Parental perception and factors associated with treatment strategies for primary nocturnal enuresis

OBJECTIVE

The aim was to investigate the factors influencing parents seeking reasonable managements for their child and their overall outlook toward primary nocturnal enuresis (PNE).

STUDY DESIGN

We recruited 93 children with PNE from enuresis clinics and requested their parents to complete questionnaires regarding their child's medical history and behavior, their methods for coping with PNE, and their perception of enuresis. Logistic regression models were applied to investigate factors influencing the parents to adopt a positive approach toward enuresis and to subsequently seek a medical consultation.

RESULTS

One-third of the parents had an encouraging attitude toward children with PNE, whereas slightly less than half reacted with anger. The more educated the father or the younger the child with NE, the larger the possibility of the parents utilizing a positive approach, such as encouragement, for coping with NE. Factors that influenced parents to seek medical consultation for NE were socioeconomic status, maternal educational level, and the age and birth order of their child.

DISCUSSION

From our results, angry and frustrated parents (43.0%) were significantly more likely to punish their child for bedwetting than were parents who approached NE positively (comfort and encouragement; 33.3%). A lack of encouragement may negatively affect the self-esteem of children with NE. Moreover, an individual's self-esteem or confidence, both of which can help them eliminate NE, determines the person's behavioral response to bedwetting. In our study, approximately 50% of the parents who approached NE positively (comfort and encouragement) or inconsistently (ambivalence) reported that they comforted their child after bedwetting.

CONCLUSIONS

Nearly half the parents reacted angrily to children with NE, and some parents even punished their child. The parents' socioeconomic background, education, and the age and birth order of the child were the factors associated with their seeking active treatment for NE. A father's education and young age of the child were factors that influenced parents who preferred positive approaches, such as encouragement, for coping with NE.

Association of Sleep Disordered Breathing with Mono-Symptomatic Nocturnal Enuresis: A Study among School Children of Central India

OBJECTIVE

To study the prevalence of primary monosymptopomatic nocturnal enuresis (PMNE) in children aged 5-10 year and to find its association with sleep disordered breathing (SDB) by using a 22 item pediatric sleep related breathing disorder (SRBD) scale.

METHODS

This was a school based cross sectional epidemiological study from July 2015 to November 2015. A questionnaire seeking information on socio-demographic variables, nocturnal enuresis (NE) frequency, school performance and a validated 22 item pediatric sleep related breathing disorder scale (SRBDs) was distributed to 1820 pupils in three primary schools.

RESULTS

A total of 1528(83.95%) questionnaires were retrieved. Out of 1528 forms, 182(11.9%) forms were incomplete for requested information and hence 1346 (73.9%) questionnaires were finally analyzed. The prevalence of NE was found to be 12.7% (95% CI; 11-14.6), whereas prevalence of primary nocturnal enuresis (PMNE) was 8.2% (95% CI; 7.1-10.1). SRBD scale score >0.33 (adjusted OR: 2.87; 95%CI: 1.67-4.92), paternal history of enuresis in childhood (adjusted OR:4.96; 95% CI: 2.36-10.45), and inappropriate toilet training (adjusted OR: 1.64; 95% CI: 1.01-2.66) were independently associated with PMNE.

CONCLUSION

Sleep disordered breathing, inappropriate toilet training and a history of childhood NE in father were found to be significant risk factors for PMNE in the present study. Thus, these findings suggest that it is imperative to rule out SDB in PMNE patients as they may require different therapeutic interventions.
