  1. 11. Contact allergy in Swedish adolescents : results from the BAMSE cohort study

    Författare :Maria Lagrelius; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Contact allergy affects about 20-25% of adults in the general population, but it is not completely clear how common it is among children and adolescents. Contact allergy is caused by skin contact to sensitizing substances. LÄS MER

  3. 13. Patch testing with palladium and aluminium, epidemiological and experimental studies

    Författare :Lisbeth Rosholm Comstedt; Yrkes- och miljödermatologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Contact allergy to palladium; prevalence of metal allergy; patch testing with palladium; natrium tetrachloropalladate; palladium chloride; Finn Chamber; patch testing with aluminium; isolated palladium allergy; patch test system; adjuvants in patch testing; delayed hypersensitivty reaction;

    Sammanfattning : AbstractThe aim of this thesis was to investigate the prevalence and significance of contact allergy to palladium from a Swedish perspective. Our initial findings made it necessary to also explore the importance of the metal aluminium used in test chamber systems and the effect of aluminium chloride (Al-Cl) in patch test preparations.
