Background: The extensive vaccination programme against swine flu resulted in an increased incidence of narcolepsy among children and adolescents. There is a need to explore if these young persons' experiences have affected their trust in healthcare, their willingness to participate in future prevention programmes, and their contacts with the healthcare system. The overall aim is to identify factors important for the life-situation of children and adolescents with narcolepsy and their families, and factors that correlate with trust in healthcare. Methods/design: Data will be collected via questionnaires from all available children with narcolepsy following the vaccination and their families, as well as a control group of children with diabetes and their families. Longitudinal descriptive interviews will also be conducted with a selection of 20-25 children and their families. Techniques from media research will be used for Internet-based data collection and analysis of information relating to narcolepsy from social media. Discussion: This project will use the situation of young persons with narcolepsy after the swine flu vaccination as a case to build a model that can be used in situations where trust in healthcare is essential. This model will be based on findings from the included studies on how trust is influenced by support, quality of life, burden of disease, impact on family, and use of social media. The model developed in this project will be beneficial in future situations where trust in healthcare is essential, such as new pandemic outbreaks but also for " everyday" adherence to health advice.

Workers often attribute poor sleep to factors at work. Despite the large number of workers with sleep disturbances, there is a lack of consensus on the relationship between the work environment and sleep. The purpose of this systematic review therefore was to conduct a comprehensive evaluation. To this end, we employed standardized methods to systematically locate, review, and tabulate the results of prospective or randomized studies of the impact of work factors on sleep disturbances. From the 7981 articles located in five databases, 24 fulfilled our inclusion criteria and formed the base of the review including meta-analyses of the effect sizes. Results showed that the psychosocial work variables of social support at work, control, and organizational justice were related to fewer sleep disturbances, while high work demands, job strain, bullying, and effort-reward imbalance were related to more future sleep disturbances. Moreover, working a steady shift was associated with disturbances while exiting shift work was associated with less disturbed sleep. We conclude that psychosocial work factors and the scheduling of work have an impact on sleep disturbances and this might be utilized in the clinic as well as for planning work environments. Future research needs to employ better methodology and focus on underlying mechanisms.

This 10-year follow-up prospective study aimed to evaluate the effects of treatment with a mandibular protruding device (MPD) on respiratory parameters and subjective symptoms in patients with obstructive sleep apnea (OSA) or snoring. Seventy-seven consecutive patients diagnosed with OSA or snoring were treated with an MPD. At baseline and the 10-year follow-up, a polygraphic examination and questionnaires on sleep quality were administrated and weight, and neck size was measured. At the 10-year follow-up, we examined 64 of the 77 patients and recorded their current treatment (45 MPD, 9 continuous positive airway pressure (CPAP), and 10 no treatment). For MPD patients, 89 % reported MPD use every night and 9 % several nights a week. Compared to baseline, MPD users with OSA had a significantly decreased oxygen desaturation index (ODI) (p = 0.006) and increased lowest arterial oxygen saturation, SaO(2) nadir (p = 0.007) after 10 years. MPD treatment was successful for 70 % of OSA patients, yet 89 % subjectively considered themselves cured, indicating overestimation of the treatment effect. OSA patients who responded to treatment maintained baseline weight and neck size, while these increased for non-responders. Of the baseline snorers still using an MPD, 93 % maintained an ODI value of < 5. All CPAP users had an ODI value of < 5. Both OSA and snorers using an MPD had significantly fewer self- and relative reports of snoring, apnea, daytime tiredness, and poor night sleep quality (p < 0.001). MPD treatment is well tolerated and effective in a long-term, 10-year perspective. Weight gain may jeopardize MPD effects. Both patients and relatives reported significantly less snoring and fewer periods of apnea.

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.

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.
