Predictors of response and adherence to enuresis alarm therapy-a confirmatory study.

AIM: To look for predictors to response and adherence to the enuresis alarm while exploring the possibility of families managing therapy independently. METHODS: We used a body-worn alarm linked to a smartphone app. Subjects with enuresis were recruited both via paediatric nurses and independently as families bought the alarm and downloaded the app on their own. RESULTS: We recruited 385 nurse-supported and 1125 independent subjects. Many (79.9%) dropped out before 8 weeks, but among adherent subjects 48.2% had a full or partial response. Age was a predictor of non-response (p = 0.019). Daytime incontinence did not influence response. If enuresis frequency did not decrease during the first 4 weeks of therapy the chance of response was very small (p < 0.001). Adherence was higher among subjects supported by a nurse (p < 0.001), but for adherent subjects the outcome was similar regardless of nurse support (p = 0.554). CONCLUSIONS: Daytime incontinence is no contraindication to enuresis alarm therapy. Treatment can be managed independently by the families, but adherence is enhanced by nurse support. Alarm treatment should be reassessed after 4 weeks. Enuresis alarm treatment guidelines need to be updated.

Can enuresis alarm therapy be managed by the families without the support of a nurse? A prospective study of a real-world sample.

AIM: The alarm is the first-line treatment of nocturnal enuresis. However, the therapy is labour-intensive for both families and healthcare providers. Our aim was to see whether the treatment could be successfully used by the families, without support from healthcare providers. METHODS: An alarm linked to an application on a parent's smartphone was used. The app recorded enuretic events and gave instructions. Group A were children supported by a nurse. Group B were patients whose families had bought the alarm and downloaded the app independently. RESULTS: There were 196 children in group A and 202 in group B. The percentages of full responders, partial responders, non-responders and dropouts were 18.4%, 20.4%, 22.4% and 38.8% in group A and 13.4%, 11.4%, 14.9% and 60.4% in group B. The risk for dropping out of therapy was higher in group B (p < 0.001), whereas the chance for adherent children to become dry did not differ between the groups (p = 0.905). CONCLUSION: For families who are able to adhere to alarm therapy the chance of success is just as good when managed independently as when supported by a nurse. But the latter children will have a greater chance of adhering to the full treatment.

The value of case history and early treatment data as predictors of enuresis alarm therapy response.

BACKGROUND AND AIM: Two central problems with the enuresis alarm are the family workload and the lack of predictors of therapy response. We wanted to look at predictors of alarm response in a setting reflecting clinical reality. METHODS: An alarm linked to a smartphone app was provided to enuretic children managed at pediatric outpatient wards. Baseline data (sex, age, daytime incontinence, urgency, previous therapies, arousal thresholds and baseline enuresis frequency) were recorded. Further information, such as enuretic episodes and actual alarm use, was gathered via the app during therapy. Therapy was given for 8-12 weeks or until 14 consecutive dry nights had been achieved. RESULTS: For the 196 recruited children the outcome was as follows: full responders (FR) 18.4%, partial responders (PR) 20.4%, nonresponders (NR) 22.4% and dropouts 38.8%. We found no clear predictors of response or adherence among baseline data. But as treatment progressed responders reduced their enuresis frequency as compared to NR (week two P = 0.003, week three and onwards P < 0.001). This is further illustrated in the Figure below. Furthermore, the children unable to complete the full treatment had more non-registered nights already from the second week (week two P = 0.005, week three P = 0.002 and so on). DISCUSSION: Anamnestic data give little predictive information regarding enuresis alarm response or adherence. Contrary to common belief neither daytime incontinence nor previous alarm attempts influenced treatment success. But after 2-4 weeks of therapy the children with a good chance of treatment success could be discerned by decreasing enuresis frequency, and the families that would not be able to comply with the full treatment showed incomplete adherence already during the first weeks. CONCLUSIONS: Maybe the enuresis alarm strategy should be changed so that the treatment is reassessed after one month and only children with a high chance of success continue. This way, unnecessary frustration for the families of therapy-resistant children may be reduced.

Fecal disimpaction in children with enuresis and constipation does not make them dry at night.

BACKGROUND: Constipation, daytime incontinence and nocturnal enuresis often overlap. Treatment of constipation has been shown to be an important aspect of therapy for children with daytime incontinence. However, the value of fecal disimpaction, as a part of constipation therapy, in children with enuresis has not been evaluated. AIM: Our aim was to evaluate the antienuretic effect of fecal disimpaction in children with enuresis and concomitant constipation. METHODS: The bladder and bowel function was assessed noninvasively in children aged six to ten years who sought help for enuresis for the first time. If they were constipated according to the Rome IV criteria or had a rectal diameter exceeding 30 mm, as assessed by ultrasound, they were given standard evacuation with mini-enemas and macrogol therapy for at least two weeks. Enuresis frequency was documented 14 nights preceding and following therapy. RESULTS: In total, 66 children (20 girls, 46 boys) were evaluated, 23 (35%) of whom were constipated. There were no differences in age, sex or baseline bladder function between the two groups. The enuresis frequency per two weeks was 9.8 ± 4.1 nights before and 9.3 ± 5.1 nights after constipation therapy (p = 0.43). DISCUSSION: This study found that fecal disimpaction in children with enuresis who are also constipated did not alleviate nocturnal enuresis. Bowel problems may still need to be addressed but the child should not be given the false hope that this approach alone will make them dry at night. It might be that evidenced based therapies, such as the enuresis alarm and desmopressin, could be less efficient in children with enuresis and constipation unless their bowel disturbance is first properly addressed. CONCLUSIONS: Fecal disimpaction in children with enuresis and concomitant constipation will, by itself, not make the children dry at night.

Daytime urotherapy in nocturnal enuresis: a randomised, controlled trial.

OBJECTIVE: According to international guidelines, children with enuresis are recommended urotherapy, or basic bladder advice, before treatment with evidence-based alternatives such as the enuresis alarm is given. The efficacy of this strategy has, however, not been supported by controlled studies. We wanted to test if basic bladder advice is useful in enuresis. DESIGN: Randomised, controlled trial. SETTING: Paediatric outpatient ward, regional hospital. PATIENTS: Treatment-naïve enuretic children aged ≥6 years, with no daytime incontinence. INTERVENTIONS: Three groups, each during 8 weeks: (A) basic bladder advice-that is, voiding and drinking according to a strict schedule and instructions regarding toilet posture, (B) enuresis alarm therapy and (C) no treatment (control group). MAIN OUTCOME MEASURES: Reduction in enuresis frequency during week 7-8 compared with baseline. RESULTS: The median number of wet nights out of 14 before and at the end of treatment were in group A (n=20) 12.5 and 11.5 (p=0.44), in group B (n=22) 11.0 and 3.5 (p<0.001) and in group C (n=18) 12.5 and 12.0 (p=0.55). The difference in reduction of enuresis frequency between the groups was highly significant (p=0.002), but no difference was found between basic bladder advice and controls. CONCLUSIONS: Urotherapy, or basic bladder advice, is ineffective as a first-line treatment of nocturnal enuresis. Enuretic children who are old enough to be bothered by their condition should be offered treatment with the alarm or desmopressin. TRIAL REGISTRATION NUMBER: NCT03812094.

The clinical presentation of acute bacterial meningitis varies with age, sex and duration of illness.

AIM: This Swedish study reviewed differences in clinical presentation and laboratory findings of acute bacterial meningitis in children aged one month to 17 years in Västerbotten County, Sweden. METHODS: A register-based study was performed for the period 1986 to 2013 using the Västerbotten County Council's patient registration and laboratory records at the Department of Laboratory Medicine at Umeå University Hospital. The medical records were reviewed to extract data and confirm the diagnosis. RESULTS: We found 103 cases of acute bacterial meningitis, and Haemophilus influenzae was the most common pathogen, causing 40.8% of all cases, followed by Streptococcus pneumoniae at 30.1% and Neisseria meningitidis at 9.7%. Significant differences in clinical presentation and laboratory findings were found. Younger children were more unwell than older ones and had more diffuse symptoms on admission. In addition, important sex-related differences were found that might explain the higher case fatality rates for boys than girls. For example, boys tended to have a higher disturbance in the blood-brain barrier, which is known to be a negative prognostic factor. CONCLUSION: This study showed that clinical presentation for acute bacterial meningitis varied with age and sex and, to a lesser extent, on the duration of the illness.
