- Background: The prevalence of atopic dermatitis (AD) has increased over several decades and now affects about one-fifth of all children in high-income countries (HICs). While the increase continues in lower-income countries, the prevalence of AD might have reached a plateau in HICs.Objectives: To investigate trends in the prevalence of AD and atopic comorbidity in schoolchildren in Sweden.Methods: The study population consisted of three cohorts of children (median age 8 years) in Norrbotten, Sweden, for 1996 (n = 3430), 2006 (n = 2585) and 2017 (n = 2785). An identical questionnaire that included questions from the International Study of Asthma and Allergies in Childhood (ISAAC) protocol was used in all three cohorts. Trends in AD prevalence were estimated, as well as trends in atopic comorbidity. AD prevalence was estimated both according to the ISAAC definition of AD and by adding the reported diagnosis by a physician (D-AD).Results: The prevalence of AD decreased in the last decade, from 22.8% (1996) and 21.3% (2006) to 16.3% (2017; P < 0.001). The prevalence of D-AD was lower, but the same pattern of decrease was seen, from 9.3% (1996) and 9.4% (2006) to 5.7% (2017; P < 0.001). In all three cohorts, AD was more common among girls than boys (18.9% vs. 13.8% in 2017; P < 0.001). Children from the mountain inlands had a higher prevalence of AD than children from coastal cities (22.0% vs. 15.1% in 2017; P < 0.001). In comparing D-AD, there were no significant differences between the sexes or between inland or coastal living. Concomitant asthma increased over the years from 12.2% (1996) to 15.8% (2006) to 23.0% (2017; P < 0.001). Concomitant allergic rhinitis and allergic sensitization increased from 1996 (15.0% and 27.5%) to 2006 (24.7% and 49.5%) but then levelled off until 2017 (21.0% and 46.7%).Conclusions: The prevalence of AD among schoolchildren in Sweden decreased over the study period, whereas atopic comorbidity among children with AD increased. Although a decrease was seen, AD is still common and the increase in atopic comorbidity among children with AD, especially the increase in asthma, is concerning.

- Background Occupational exposure to skin irritants, in particular to water, is an important risk factor for hand eczema. Objectives To assess occupational skin exposure to water in the general population. Methods As part of a public health survey in Stockholm, Sweden, 18 267 gainfully employed individuals aged 18-64 years completed a questionnaire with previously validated questions regarding occupational skin exposure to water. Results Altogether 16% reported exposure to water for (1/2) h or more a day, and 13% reported exposure to water more than 10 times a day. Furthermore, 7% reported water exposure of more than 2 h and 6% of more than 20 times a day. Women reported more water exposure than men and many female-dominated occupations were seen to comprise water exposure. Women were also more exposed than men within the same jobs. Young adults were more exposed than older. A total of 18% were employed in high-risk occupations for hand eczema. Fifty-nine per cent of individuals employed in high-risk occupations reported water exposure at work, compared with 11% in low-risk occupations. Conclusions A total of 20% of the population of working age acknowledged occupational skin exposure to water, which was found to be more common in young adults and women. Using job title as a proxy for water exposure gives an underestimation due to misclassification. In assessing occupational skin exposure to water, both exposure time and frequency should be considered.

- Background Assessment of hand eczema in a clinical study has been achieved using a scoring system which documents extent of eczema on different areas of the hand. Objectives To investigate whether the same scoring system could be used by patients to communicate current status of hand eczema. Methods In a study of 62 patients (36 women and 26 men, age range 1975 years), the patients own assessment was compared with the assessment by a dermatologist and a dermatological nurse. Standardized information was given to the patient and the form was filled in independently by the patient, the nurse and the dermatologist, during the patients visit to the clinic. Individual area scores were summed to a total score. Results The overall agreement was good, with an interclass correlation (ICC) of 0.61 between patient and dermatologist for the total score. The ICC between nurse and dermatologist was 0.78. Differences between observers were more pronounced for the more severe cases - those with higher numerical scores as assessed by the dermatologist. There was a tendency for women and for patients over the median age of 44 years to set a lower point score than the dermatologist. The concordance of observations from individual anatomical areas was higher for fingertips and nails and lower for the palm and dorsum of the hand. Conclusions Patients are able to report the extent of hand eczema with good accuracy. Self-assessment protocols for hand eczema may well have a place in the monitoring of hand eczema extent over time.

- Background When this study was initiated, no previous studies comparing methotrexate and ciclosporin for moderate to severe plaque psoriasis had been performed. Objectives To compare the effectiveness, quality of life and side-effects of methotrexate and ciclosporin treatments in a context reflecting normal clinical practice. Methods Eighty-four patients with moderate to severe plaque psoriasis were randomized to treatment with methotrexate or ciclosporin for 12 weeks. The primary outcome was the Psoriasis Area and Severity Index (PASI). The secondary outcome was quality of life, measured by the Dermatology Life Quality Index (DLQI) and the 36-item Short Form Health Survey (SF-36). A visual analogue scale (VAS) was used for patients' assessment. Results Sixty-eight patients started treatment and were included in the analysis. Dropout before initiation of treatment was higher in the ciclosporin group. Mean PASI change from baseline at 12 weeks was 58% in the methotrexate group and 72% in the ciclosporin group, showing ciclosporin to be more effective than methotrexate. Improvement of the VAS score was higher in the ciclosporin group. The methotrexate group showed a greater improvement in the subscale Physical Functioning of the SF-36. No significant difference between the groups was found for DLQI. Conclusions Treatment with methotrexate or ciclosporin for chronic plaque psoriasis brings satisfactory disease control, improved quality of life and tolerable side-effects. A statistically significant difference in effectiveness between treatment groups was recorded, showing ciclosporin to be more effective than methotrexate in a short-term perspective.
