RESUMEN

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.

RESUMEN

AIM: There is limited knowledge about the perceptions of HPV vaccination in middle-school children. This qualitative study aimed to explore their views. METHODS: We conducted focus group interviews with children, 10-11 years of age, who had been offered HPV vaccination through the school health services in mid-north Sweden in spring of 2023. Data were analysed with qualitative content analysis. RESULTS: This study included six focus group interviews with 49 children (boys n = 29; girls n = 20), mean of 11 years of age. Participating children expressed the need to feel safe to be of utmost importance and the means to do so was to be prepared and informed by someone the child trusted. The school nurse was perceived as the expert, best suited to provide factual information, support and motivation, both to children and their parents. CONCLUSION: We confirm that healthcare providers' recommendations are crucial for HPV vaccine acceptance also from the child's perspective. Improved information about HPV vaccination to children is necessary. Children's right to participate on their own terms is not fulfilled today. Vaccine promotion, both to children and parents, should be actively managed by the school nurse.

RESUMEN

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.

RESUMEN

By collecting and analyzing diapers, we identified a >6-fold increase in carriage of extended-spectrum ß-lactamase (ESBL)-producing Enterobacteriaceae for healthy preschool children in Sweden (p<0.0001). For 6 of the 50 participating preschools, the carriage rate was >40%. We analyzed samples from 334 children and found 56 containing >1 ESBL producer. The prevalence in the study population increased from 2.6% in 2010 to 16.8% in 2016 (p<0.0001), and for 6 of the 50 participating preschools, the carriage rate was >40%. Furthermore, 58% of the ESBL producers were multidrug resistant, and transmission of ESBL-producing and non-ESBL-producing strains was observed at several of the preschools. Toddlers appear to be major carriers of ESBL producers in Sweden.

RESUMEN

OBJECTIVE: Recent clinical studies have suggested an increased risk of elevated arterial pressure in patients with hydronephrosis. Animals with experimentally induced hydronephrosis develop hypertension, which is correlated to the degree of obstruction and increased oxidative stress. In this prospective study we investigated changes in arterial pressure, oxidative stress, and nitric oxide (NO) homeostasis following correction of hydronephrosis. METHODS: Ambulatory arterial pressure (24 h) was monitored in pediatric patients with hydronephrosis (n = 15) before and after surgical correction, and the measurements were compared with arterial pressure measurements in two control groups, i.e. healthy controls (n = 8) and operated controls (n = 8). Markers of oxidative stress and NO homeostasis were analyzed in matched urine and plasma samples. RESULTS: The preoperative mean arterial pressure was significantly higher in hydronephrotic patients [83 mmHg; 95% confidence interval (CI) 80-88 mmHg] than in healthy controls (74 mmHg; 95% CI 68-80 mmHg; p < 0.05), and surgical correction of ureteral obstruction reduced arterial pressure (76 mmHg; 95% CI 74-79 mmHg; p < 0.05). Markers of oxidative stress (i.e., 11-dehydroTXB2, PGF2α, 8-iso-PGF2α, 8,12-iso-iPF2α-VI) were significantly increased (p < 0.05) in patients with hydronephrosis compared with both control groups, and these were reduced following surgery (p < 0.05). Interestingly, there was a trend for increased NO synthase activity and signaling in hydronephrosis, which may indicate compensatory mechanism(s). CONCLUSION: This study demonstrates increased arterial pressure and oxidative stress in children with hydronephrosis compared with healthy controls, which can be restored to normal levels by surgical correction of the obstruction. Once reference data on ambulatory blood pressure in this young age group become available, we hope cut-off values can be defined for deciding whether or not to correct hydronephrosis surgically.

RESUMEN

To promote the standardization of nephro-uroradiological terms used in children, the European Society of Paediatric Radiology uroradiology taskforce wrote a detailed glossary. This work has been subsequently submitted to European experts in pediatric urology and nephrology for discussion and acceptance to improve the quality of radiological reports and communication between different clinicians involved in pediatric urology and nephrology.

RESUMEN

AIM: There have not been any continence-specific measurement tools in Swedish that have allowed clinicians to investigate the quality of life (QoL) in children with bladder dysfunction. This study evaluated the QoL in Swedish children with nocturnal enuresis and tested the reliability of a Swedish translation of the Paediatric Incontinence Questionnaire (PinQ). METHODS: This prospective study comprised 46 children aged six to 18 years with nocturnal enuresis, who completed the PinQ after it was translated into Swedish. It was completed twice by 33 patients, and these responses were included in the test-retest evaluation. RESULTS: The self-reported mean sum score for the whole group was 26.3 ± 13.37 (range: 5-58), and the most affected domains were social relations with peers and self-esteem. The highest individual scores were four, three or two for 71.7%, 17.4% and 10.9% of the study population, respectively. Cronbach's alpha was 0.87 for the whole questionnaire, indicating good internal consistency. The test-retest stability was excellent, with an intra-class correlation coefficient of 0.76. CONCLUSION: Children with nocturnal enuresis had impaired self-esteem, and their impaired QoL affected their relationships with friends. The Swedish version of the PinQ proved to be a reliable tool that will be used in further studies.

RESUMEN

Enuresis was historically viewed as a primarily psychiatric disorder, but this understanding has changed dramatically since the end of the last century, when it became clear that somatic factors, such as nocturnal polyuria as a result of vasopressin deficiency, nocturnal detrusor overactivity and high arousal thresholds, all play a crucial role in enuresis pathogenesis. It has also become clear that enuresis is inherited in the majority of cases, although the correlation between genotype and enuretic phenotype is not straightforward. The standard view of enuresis as being the result of either (i) nocturnal polyuria and high arousal thresholds; or (ii) nocturnal detrusor overactivity and high arousal thresholds has become well-established, but further research now complicates the picture. First, psychological/psychiatric problems are overrepresented in enuresis, and might in a minority of cases have a causal or aggravating role. Second, nocturnal polyuria is not always linked to vasopressin deficiency. Third, nocturnal detrusor overactivity is in itself pathogenetically heterogeneous, and could be linked to constipation. Fourth, the sleep of enuretic children might be "deep," but possibly also disturbed (by obstructed airways or a distended or contracting bladder). These children might have high arousal thresholds because of the enuresis instead of the other way around. The same might possibly be said about nocturnal polyuria. Taking these new insights into account, a new model of enuresis pathogenesis is presented, which is more complicated but hopefully also more true than the standard consensus.

RESUMEN

AIM: The impact of the original International Children's Continence Society (ICCS) terminology document on lower urinary tract (LUT) function resulted in the global establishment of uniformity and clarity in the characterization of LUT function and dysfunction in children across multiple healthcare disciplines. The present document serves as a stand-alone terminology update reflecting refinement and current advancement of knowledge on pediatric LUT function. METHODS: A variety of worldwide experts from multiple disciplines within the ICCS leadership who care for children with LUT dysfunction were assembled as part of the standardization committee. A critical review of the previous ICCS terminology document and the current literature was performed. Additionally, contributions and feedback from the multidisciplinary ICCS membership were solicited. RESULTS: Following a review of the literature over the last 7 years, the ICCS experts assembled a new terminology document reflecting current understanding of bladder function and LUT dysfunction in children using the resources from the literature review, expert opinion and ICCS member feedback. CONCLUSIONS: The present ICCS terminology document provides a current and consensus update to the evolving terminology and understanding of LUT function in children. Neurourol.

RESUMEN

BACKGROUND: Sweden introduced a school-based human papillomavirus (HPV) vaccination programme in 2012, and school nurses are responsible for managing the vaccinations. The aim of the present study was to investigate the attitudes and experiences of school nurses regarding the school-based HPV vaccination programme 1 year after its implementation. METHODS: Data were collected using a web-based questionnaire in the spring of 2013, and 83.1% (851/1024) of nurses responded. RESULTS: There were strong associations between the nurses' education about the HPV vaccine and their perceived knowledge about the vaccine and a favourable attitude towards vaccination (both p < 0.001). School nurses who received a high level of education were more likely to have a positive attitude to HPV vaccination compared with nurses with little education about HPV vaccination (adjusted odds ratio [OR] = 9.8; 95% confidence interval [CI]: 3.797-25.132). Nurses with high perceived knowledge were more likely to have a positive attitude compared with those with a low level of perceived knowledge (OR = 2.5; 95% CI: 1.299-4.955). If financial support from the government was used to fund an additional school nurse, nurses were more likely to have a positive attitude than if the financial support was not used to cover the extra expenses incurred by the HPV vaccination (OR = 2.1; 95% CI: 1.051-4.010). The majority, 648 (76.1%), had been contacted by parents with questions about the vaccine, mostly related to adverse effects. In addition, 570 (66.9%) stated that they had experienced difficulties with the vaccinations, and 337 (59.1%) of these considered the task to be time-consuming. CONCLUSIONS: A high level of education and perceived good knowledge about HPV are associated with a positive attitude of school nurses to the HPV vaccination programme. Thus, nurses require adequate knowledge, education, skills and time to address the questions and concerns of parents, as well as providing information about HPV. Strategic financial support is required because HPV vaccination is a complex and time-consuming task.

RESUMEN

AIM: Although there is a known association between enuresis and snoring or sleep apnoeas, respiration during sleep has not been thoroughly studied in enuretic children. This study was performed with the aim of filling this gap in our knowledge. METHODS: Thirty-four children with therapy-resistant enuresis, but no history of heavy snoring or sleep apnoeas, underwent sleep registrations, including standard electroencephalography (EEG) and electrooculography (EOG) as well as registration of oxygen saturation, respiratory effort and nasal air flow. To assess nasal airway patency, rhinomanometry and acoustic rhinometry were performed before and after nasal decongestion. RESULTS: The children were found to have a higher than expected apnoea hypopnoea index (AHI), due to a high frequency of hypopnoeas. They were also noted to have a tendency for respiratory arousals. Standard polysomnographic variables were normal. CONCLUSION: We provide baseline data of nocturnal respiration in enuretic children. The children were found to have subclinical signs of disordered respiration. This may be one of the explanations for their high arousal thresholds.

RESUMEN

AIM: According to a number of small case series, orthodontic treatment may have anti-enuretic effects. Thus, we evaluated whether widening of the palate can alleviate enuresis and whether prognostic information can be gained from examining children's nocturnal respiration and nasal airway dimensions. METHODS: Children with therapy-resistant enuresis underwent polysomnography, focusing on nocturnal respiration, and had their nasal airways examined. Rapid maxillary expansion was performed, widening the maxilla by approximately 0.5 cm. The dental appliance was removed after 6 months. Enuresis frequency was evaluated four times: at baseline, with the orthodontic apparatus in situ, after completed maxillary expansion and 1 year post-treatment. RESULTS: Of the 34 children recruited, one dropped out due to oral discomfort. The numbers of wet nights per week on the four assessment occasions were 5.48 ± 1.48, 5.12 ± 1.73, 3.09 ± 2.49 and 2.63 ± 2.81; p < 0.001. The proportions of responders, intermediate responders and non-responders during treatment were 21.2%, 27.3% and 51.5%, respectively. Responders were found to have a lower enuresis frequency at baseline (p = 0.001) and to have larger nasal airway dimensions (p = 0.01). CONCLUSION: Orthodontic widening of the palate may be curative in a subgroup of children with therapy-resistant enuresis.

RESUMEN

AIM: To explore why parents refused to allow their 10- to 12-year-old daughters to receive the human papillomavirus (HPV) vaccination from the Swedish school-based vaccination programme. METHODS: Individual interviews with 25 parents who had been offered, but not consented to, their daughters receiving the HPV vaccination. RESULTS: Five themes emerged through the interviews: 1) she is just a little girl, 2) inadequate information, 3) not compatible with our way of life, 4) scepticism about the vaccination and 5) who can you trust? The parents made their decisions with their child's best interests in mind. This was not considered the right time, and the vaccine was perceived as unnecessary and different from other vaccines. Mistrust in Government recommendations and a lack of evidence or information were other reasons to decline. CONCLUSION: The decision-making process was complex. These parents preferred to wait until their daughter was older and believed the information they received from the school health system was insufficient. The results indicate that a more flexible HPV vaccination schedule may improve vaccine uptake. This includes more transparent information about the virus and the vaccine and information about who to contact to get the daughter vaccinated at a later date.

RESUMEN

BACKGROUND: The voiding chart is part of the initial evaluation of enuresis, since the data gathered this way are assumed to carry predictive information. However, there is little evidence that the voiding chart actually does predict therapy response. Lundmark & Nevéus performed a pilot investigation in 2020 and found that anamnestic and voiding chart data did not predict response to second-line therapies. This study aims at evaluating whether these findings could be replicated. PATIENTS AND METHODS: This is an evaluation of clinical practice. All patients in a tertiary outpatient clinic with enuresis resistant to first-line therapy (i.e. the enuresis alarm and desmopressin medication) during the evaluation period were included in the study. Baseline anamnestic data focused on bladder and bowel habits, were gathered and the families were instructed to complete a voiding chart including measurements of nocturnal urine production. The children were then treated in accordance with international guidelines, which are anticholinergics and antidepressants as second- and third-line treatment, respectively. Desmopressin was added if needed. RESULTS: In total, 70 patients were included. At the end of the study 37 of these patients were dry, 11 patients were still wetting their beds and 22 patients were lost to follow-up. Of the dry patients 21 became dry on anticholinergics (and/or mirabegron, with or without desmopressin), five on tricyclic antidepressants (with or without desmopressin), seven after a new attempt with the alarm and five became dry spontaneously. The only statistically significant differences between responders and non-responders to the various treatments were that children responsive to anticholinergics had harder and more infrequent stools (p = 0.04 and p = 0.03, respectively). CONCLUSION: This study found that anamnestic and voiding chart data do not predict response to treatment in children with therapy-resistant enuresis. Because of this and the fact that we lose some children who need our help by demanding that they complete a voiding chart before initiating treatment, we question the use of this instrument in the evaluation of therapy-resistant enuresis.

RESUMEN

BACKGROUND: The reabsorption of filtered plasma proteins, hormones and vitamins by the renal proximal tubules is vital for body homeostasis. Studies of megalin-deficient mice suggest that the large multi-ligand endocytic receptor megalin plays an essential role in this process. In humans, dysfunctional megalin causes the extremely rare Donnai-Barrow/Facio-Oculo-Acustico-Renal (DB/FOAR) syndrome characterized by a characteristic and multifaceted phenotype including low-molecular-weight proteinuria. In this study, we examined the role of megalin for tubular protein reabsorption in humans through analysis of proximal tubular function in megalin-deficient patients. METHODS: Direct sequencing of the megalin-encoding gene (LRP2) was performed in a family in which three children presented with classical DB/FOAR manifestations. Renal consequences of megalin deficiency were investigated through immunohistochemical analyses of renal biopsy material and immunoblotting of urine samples. RESULTS: In the patients, a characteristic urinary protein profile with increased urinary excretion of vitamin D-binding protein, retinol-binding protein and albumin was associated with absence of, or reduced, proximal tubular endocytic uptake as shown by renal immunohistochemistry. In the absence of tubular uptake, urinary albumin excretion was in the micro-albuminuric range suggesting that limited amounts of albumin are filtered in human glomeruli. CONCLUSIONS: This study demonstrated that megalin plays an essential role for human proximal tubular protein reabsorption and suggests that only limited amounts of albumin is normally filtered in the human glomeruli. Finally, we propose that the characteristic urinary protein profile of DB/FOAR patients may be utilized as a diagnostic marker of megalin dysfunction.

RESUMEN

Pyelonephritis in childhood may, in the worst cases, lead to long-term cardiovascular morbidity due to tubulointerstitial renal scarring. Renal damage is the end result of an interplay between (1) urinary tract anatomy and function, (2) bacterial virulence factors, and (3) the host innate immune system, which on the one hand manages bacterial clearance, but on the other causes tubulointerstitial inflammation, which underlies the renal scarring. It is unclear how common postpyelonephritic scarring is, and how many of the "scars" in fact represent congenital renal hypoplasia. We do, however, know that some situations have an increased risk for scars, i.e., large renal-uptake defects on initial renal scintigraphy or pyelonephritis in young girls with dilating vesicoureteral reflux. It seems logical that antiinflammatory or antioxidant therapy given concomitantly with antibiotics should lower the risk of postpyelonephritic scarring. Animal studies give some support to this idea, but research on humans has been surprisingly scant. In this issue of Pediatric Nephrology, we publish a study that indicates that antioxidant therapy with vitamin A or E given to children with pyelonephritis may indeed lower the risk for renal scarring. This is a track that needs to be pursued further.

RESUMEN

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.

RESUMEN

BACKGROUND: Human papillomavirus (HPV) vaccines effectively prevent, and can even eliminate, HPV-related cancers. Currently, vaccination rates are suboptimal in the national Swedish school-based vaccination program. School nurses play a key role in all aspects of the vaccination process. Therefore, this study aims to explore school nurses' perceived HPV vaccination challenges. METHODS: Seven focus group interviews were conducted with school nurses (n = 35) working in nine socio-demographically diverse municipalities in mid-Sweden. Data were analyzed using qualitative content analysis. RESULTS: Participants described difficulties in encountering and handling the diversity of reasons for vaccine hesitancy. Parents known to be skeptical of vaccines in general were seen as most difficult to reach. Uncertainty was expressed concerning the extent of professional responsibility for vaccine promotion. The informants expressed a lack of guidelines for vaccine promotion and described challenges in supporting the child's own wishes. Creating a safe space for the individual child was seen as crucial. Other problems described were the challenges of overcoming children's fear of needles, supporting unvaccinated children, and being confronted with the remaining gender inequities of the pan-gender vaccination program. CONCLUSIONS: Our results suggest that school nurses, especially those new to their profession, may benefit from training and guidance22 material on how to address vaccine hesitancy.

RESUMEN

OBJECTIVE: Dilating vesicoureteral reflux (VUR) has been linked to febrile urinary tract infection (UTI) and renal scarring. It is unclear, however, whether children with reflux should be treated surgically or medically, or just kept under close surveillance with prompt treatment of UTIs. This lack of evidence makes parental preferences a crucial factor in the choice of therapy. The Swedish Reflux Trial was set up to compare the three treatment alternatives prospectively. This paper focuses on parental experience and satisfaction after completing the trial. MATERIAL AND METHODS: A group of 203 children aged 12-24 months with reflux grade III or IV were randomly assigned to antibiotic prophylaxis (n = 69), surveillance (n = 68) or endoscopic injection treatment (n = 66) and followed closely for 2 years. Afterwards, the families were interviewed by an investigator not involved in the care of the children about their experience of the study. RESULTS: Parental satisfaction with the treatment given was high, with 53% scoring 5 and 35% 4 on a five-grade scale, with no difference between the three groups (p = 0.5). Recurrence of febrile UTI or new kidney scarring did not influence parental satisfaction. Even though the satisfaction was high regardless of therapy, parents of children in the prophylaxis group more often than others would have chosen another treatment if given a choice. CONCLUSIONS: As far as parental satisfaction and preferences are concerned, antibiotic prophylaxis, surveillance and injection treatment are equivalent treatment strategies in children with VUR.
