Practical algorithm to inform clinical decision-making in the topical treatment of atopic dermatitis
Atopic dermatitis is a chronic relapsing, inflammatory skin disorder associated with skin
barrier dysfunction, the prevalence of which has increased dramatically in developing
countries. In this article, we propose a treatment algorithm for patients with mild-tomoderate and severe atopic dermatitis flares in daily clinical practice. An international
panel of 15 dermatology and allergy experts from eight countries was formed to develop
a practical algorithm for the treatment of patients with atopic dermatitis, with a particular
focus on topical therapies. In cases of mild-to-moderate atopic dermatitis involving sensitive skin areas, the topical calcineurin inhibitor pimecrolimus should be applied twice
daily at the first signs of atopic dermatitis. For other body locations, patients should apply
a topical calcineurin inhibitor, either pimecrolimus or tacrolimus, twice daily at the first
signs of atopic dermatitis, such as pruritus, or twice weekly in previously affected skin
areas. Emollients should be used regularly. Patients experiencing acute atopic dermatitis flares in sensitive skin areas should apply a topical corticosteroid twice daily or alternate
once-daily topical corticosteroid/topical calcineurin inhibitor until symptoms improve.
Following improvement, topical corticosteroid therapy should be discontinued and patients switched to a topical calcineurin inhibitor. Maintenance therapy should include the
use of pimecrolimus once daily for sensitive areas and tacrolimus for other body locations. This treatment algorithm can help guide clinical decision-making in the treatment
of atopic dermatitis
Evaluation of the nasal provocation test for its necessity in the diagnosis of nasal allergy to house dust mite
The aim of this study was to evaluate rhinomanometric responses to nasal allergen provocation in children with allergic rhinitis sensitized to house dust mite. We studied 51 children, aged 6-16 years (mean: 11.5 +/- 2.6 years), with clinical symptoms of perennial allergic rhinitis without asthma and 20 non-atopic healthy controls in the same age range (mean: 11.8 +/- 3.8 years). All of the patients had positive skin prick test (SPT) results and serum specific IgE above 0.70 kU/I to Dermatophagoides pteronyssinus (Dp). Nasal provocation testing (NPT) was performed with increasing concentrations of Dp extracts and the nasal response was evaluated by active anterior rhinomanometry. A 100% increase of resistance in one or both nasal cavities was considered positive. There was a statistically significant difference of baseline nasal resistance (total, right and left sides) between the control and the patient groups (p < 0.001). A positive response to house dust mite allergens was recorded in 47/51 (92.2%) patients by rhinomanometry. The NPT presented no significant correlation with age, weight, height, SPT diameter, serum total and specific IgE levels to Dp and baseline nasal airway resistance values. This study suggests that a nasal provocation test with allergen is unnecessary in children with positive skin prick test and serum IgE specific to house dust mite. The rhinomanometric response to the allergen provocation does not correlate with the diameter of the skin prick test and the level of serum specific IgE
Prevalence and Risk Factors of Atopic Eczema in Turkish Adolescents
Atopic eczema (AE) is the most common childhood inflammatory skin condition. The aim of this study was to evaluate the prevalence of AE and its relation to various risk factors. In a cross-sectional study, 9,991 children ages 13 to 14 years in 61 primary schools in 32 districts of Istanbul were evaluated. The prevalence of AE and associated symptoms was assessed using the International Study of Asthma and Allergies in Childhood protocol. The relationship between risk factors and AE was evaluated using multivariate logistic regression analysis. Ten thousand nine hundred eighty-four questionnaires were distributed to 13- and 14-year-old children in 61 schools in 32 districts of Istanbul, 9,991 of which were suitable for analysis, for an overall response rate of 91.7%. There were 4,746 boys (47.9%) and 5,166 girls (52.1%) (M/F ratio 0.920). The rates of itchy rash ever, 12-month itchy rash, and doctor-diagnosed AE ever were 18.2%, 12.0%, and 2.8%, respectively. The difference between rates for itchy rash ever, 12-month itchy rash and doctor-diagnosed AE was high (12.8-31.3, 5.8-24.8, and 0-17.2, respectively) between the districts of Istanbul. Female sex, AE family history, watching television more than 5hours a day, region of the district, and tonsillectomy history were found to be significantly associated with doctor-diagnosed AE at pAE and related symptoms in Istanbul. Several risk factors were found to be associated with doctor-diagnosed AE
The effect of exposure to environmental tobacco smoke on clinical findings in asthmatic schoolchildren
children in Istanbul, Turkey
The aim of this study was to evaluate the prevalence of allergic rhinitis and its relationship with various risk factors in 6-7-year-old children living in Istanbul. A total of 11,483 children aged 6-7 years in 75 primary schools from all districts of Istanbul were surveyed. Prevalence of symptoms of allergic rhinitis was assessed using a translated version of the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. Of them, 9,875 (50.7% M, 49.3% F) questionnaires were appropriately completed by the parents. The prevalence rates of lifetime, current and physician-diagnosed allergic rhinitis were 44.3%, 29.2% and 8.1%, respectively. There was nearly a two-fold variation in the prevalence rates of rhinitis between the districts of Istanbul. Frequent paracetamol and antibiotic use in the first year of life, history of frequent upper respiratory tract infections, adenotonsillectomy, breastfeeding less than six months, dog at home or perianal redness in the first year of life, and frequent trucks passing near the home were independent risk factors
prevalence among Turkish adolescents
Background: Allergic rhinitis (AR) is a global health problem affecting many people from childhood to adulthood. The aim of this study was to evaluate the prevalence of AR and related symptoms, and to assess the risk factors, dietary habits and the Mediterranean diet affecting AR.Methods: In a cross-sectional study design, 9991 children, aged 13-14 years in 61 primary schools in 32 districts of Istanbul were evaluated. The prevalence of AR symptoms among the children was evaluated using the ISAAC protocol.Results: In our study, total of 10,984 questionnaires were distributed to 13-14 yr-old schoolchildren to 61 schools in 32 district of Istanbul and 9991 questionnaires were suitable for analysis with an overall response of 91.7%. The rates of lifetime rhinitis, rhinitis in last 12 months and lifetime doctor diagnosed AR prevalence were 53.5%, 38.3% and 4.5%, respectively. The variation among districts in the prevalence of doctor diagnosed AR was very high. The highest prevalence was about 10 times higher than in the district with the lowest prevalence (range: 1.4-14.5) of Istanbul.A family history of atopy, mother with a university degree, presence of cat at home during last 12 months and adenoidectomy were significant for increased doctor diagnosed AR risk. Additionally, although fish and other sea foods, fermented drinks made from millets and various seeds, animal fats and butter were independent risk factors for doctor diagnosed AR, fish oil and hamburger were protective foods for doctor diagnosed AR. The MD was not associated with the prevalence of doctor diagnosed AR.Conclusions: This study shows that that there are wide variations for the prevalence of AR related symptoms in 13-14 yr-old schoolchildren among districts of Istanbul in Turkey. Socio-economical, environmental factors, some dietary habits, but not Mediterranean diet may affect the prevalence of AR. (C) 2013 Elsevier Ireland Ltd. All rights reserved
