Effectiveness of alpine climate treatment for children with difficult to treat atopic dermatitis: Results of a pragmatic randomized controlled trial (DAVOS trial).

BACKGROUND: Alpine climate treatment has historically been used in Europe to treat atopic dermatitis (AD), but no randomized trials have been conducted to provide evidence for its effectiveness. OBJECTIVE: To investigate the long-term effectiveness of alpine climate treatment for children with difficult to treat AD. MATERIALS & METHODS: A pragmatic, open, randomized controlled trial was conducted. Children diagnosed with AD that was considered difficult to treat, aged between 8 and 18 years and willing to be treated in Switzerland were randomized to a six-week personalized integrative multidisciplinary treatment period in a clinical setting in the alpine climate (Switzerland) or an outpatient setting in moderate maritime climate (Netherlands). Study assessments were conducted at the Wilhelmina Children's Hospital; an electronic portal was used for the collection of questionnaire data. Primary outcomes were disease activity (SAEASI), quality of life (CDLQI) and catastrophizing thoughts (JUCKKI/JU) 6 months after intervention. Other assessments were immediately and 6 weeks after intervention. Subgroup analyses concerned asthma-related outcomes. Children were randomly assigned to either the intervention or control group using a covariate adaptive randomization method, taking age and asthma diagnosis into account. Children, parents and healthcare professionals involved in treatment were not blinded to group assignment. Data were analysed according to intention-to-treat with linear mixed-effects models for continuous outcomes. The trial is registered at Current Controlled Trials ISCRTN88136485. RESULTS: Between 14 September 2010 and 30 September 2014, 88 children were enrolled in the trial, 84 children were randomized (41 assigned to intervention, 43 to control) of whom 77 completed the intervention (38 of 41 (93%) intervention, 39 of 43 (91%) control) and 74 completed follow-up (38 of 41 (93%) intervention, 36 of 43 (84%) control). Six months after intervention there were no significant differences between the groups on disease activity (SAEASI mean difference -3.4 (95%CI -8.5 to 1.7)), quality of life (CDLQI mean difference -0.3 (95%CI -2.0 to 1.4)) and catastrophizing thoughts (JUCCKI/JU subscale mean difference -0.7 (95%CI -1.4 to -0.0)). Immediately and 6 weeks after intervention, disease activity and quality of life were significantly different in favour of alpine climate treatment. Mean differences on SAEASI were -10.1 (95%CI -14.5 to -5.8) and -8.4 (95%CI -12.2 to -4.6) and on CDLQI -1.9 (95%CI -3.3 to -0.5) and -1.5 (95%CI -2.8 to -0.3) immediately and 6 weeks after the intervention, respectively. There were no long-term differences on asthma-related outcomes. Five serious adverse events occurred during the study period, which were not thought to be related to the treatment. CONCLUSIONS & CLINICAL RELEVANCE: For children with difficult to treat AD, there was no additional long-term benefit of alpine climate treatment, in contrast to the short-term, compared to an outpatient treatment programme in moderate maritime climate, using a personalized integrative multidisciplinary treatment approach.

[Accurate assessment of heart murmurs in children: thorough medical history and physical examination required]. / Beoordeling van hartgeruisen bij kinderen: zorgvuldige anamnese en lichamelijk onderzoek vereist.

4 children, boys aged 12, 5, 1.5 and 11 years, had a heart murmur. The 12-year-old boy could also not finish a football match and appeared to have atrioseptal defects (ASD). The 1.5-year-old boy had pulmonary symptoms that were not responsive to asthma medication; he also had ASD. The 11-year-old boy had had chest pain and pressure following exertion for 2 years; he appeared to have an aortic stenosis. Symptoms disappeared in all 3 patients after surgical correction. In the 5-year-old asymptomatic boy the murmur was deemed to be innocent following medical history and physical examination. Children frequently have heart murmurs. Most heart murmurs are innocent but some are caused by heart defects. Careful evaluation of the medical history and physical examination are critical in the differentiation of innocent and pathological heart murmurs. Routine supplementary diagnostic tests in children with heart murmurs are of limited value and are often misleading. One should inquire about specific and nonspecific symptoms and also perform systematic inspection, palpation and auscultation to identify any characteristics that suggest a heart murmur caused by a heart defect.
