    Climate Change, Migration, and Allergic Respiratory Diseases: An Update for the Allergist
    (BioMed Central Ltd, 2011) D'Amato, Gennaro; Rottem, Menachem; Dahl, Ronald; Blaiss, Michael; Ridolo, Erminia; Cecchi, Lorenzo; Rosario, Nelson; Motala, Cassim; Ansotegui, Ignacio; Annesi-Maesano, Isabella; the WAO Special Committee on Climate Change and Allergy
    Local climate changes can impact on a number of factors, including air pollution, that have been shown to influence both the development and attacks of allergic respiratory diseases, and they thus represent an important consideration for the allergist. Migration involves exposure to a new set of pollutants and allergens and changes in housing conditions, diet and accessibility to medical services, all of which are likely to affect migrants' health. This review provides an update on climate change, migration, and allergy and discusses factors for consideration when making recommendations for local allergy service provision, and for assessing an individual patient's environmental exposures.

    Diagnostic testing in allergy
    (2009) Motala, Cassim; Hawarden, Diane Athena
    Atopy is a personal and/or familial tendency, usually in childhood or adolescence, to become sensitised and produce IgE antibodies in response to ordinary exposure to allergens, usually proteins. As a consequence, such individuals can develop the typical symptoms of asthma, rhinoconjunctivitis or eczema.

    Environmental and occupational respiratory diseases - 1040. Associations between asthma and bronchial hyper-responsivness with allergy and atopy phenotypes in urban black South African teenagers
    (BioMed Central Ltd, 2013) Levin, Michael; Muloiwa, Rudzani; Motala, Cassim
    Epidemiological studies in South Africa show increasing prevalence rates of asthma and allergic sensitisation in both urban and rural Black African communities, and narrowing of the urban-rural gradient. There is a paucity of current data on bronchial hyper-responsiveness (BHR) in urban Black African children, associations between asthma and BHR and the relationship between BHR, allergen sensitisation and other atopic diseases.
