BACKGROUND A nation-wide Norwegian Patch Test Registry (NOLAR) was established in 2005 as a collaboration between six dermatology departments. International, multi-centre studies have documented great variability in the frequency of positive patch test reactions, considered as mainly due to heterogeneity of test populations. OBJECTIVES To analyse the variability of positive test reactions by ...

Background Atopy varies in people of different ages owing to physical conditions and exposure allergens. We aimed cluster based on atopic severity using K-means analysis identify incidence, severity, as well the association among peripheral eosinophils, IgE sensitisation. Methods Consecutive patients (n = 7654) with allergic symptoms undergoing allergen-specific tests were included from 2013 20...

Background: The standard patch test is known as the most reliable test to identify and confirm causative agents of allergic contact dermatitis (ACD). Previous studies have shown that the prevalence of specific allergens varies by geographic area. The results of patch test in patients visiting our dermatology clinics with suspected ACD were prospectively investigated and compared with those repo...

Controversy persists as to whether helminth infections cause or protect against asthma and atopy. The aim of this study was to investigate the effects of helminth infection on asthma and atopy among Bangladeshi children. A total of 912 children aged 4.5 years (mean = 54.4, range = 53.5-60.8 months) participated in a cross-sectional study nested into a randomized controlled trial in Bangladesh. ...

OBJECTIVE To assess pulmonary function and the prevalence of atopy in school-age children who were very low birth weight as infants and to compare those who had bronchopulmonary dysplasia to those who did not. METHOD We studied 85 (39 male and 46 female) at a mean age of 84 (range, 62 to 107) months who were very low birth weight infants. Bronchopulmonary dysplasia was defined as oxygen depen...

BACKGROUND Obstructive sleep apnoea syndrome is associated with significant morbidity. A high prevalence of obstructive sleep apnoea (OSA) symptoms has been reported in patients with asthma and chronic obstructive pulmonary disease (COPD). There are limited studies regarding relationship between atopy and OSA. OBJECTIVE To study the risk of obstructive sleep apnoea among middle aged chronic o...
