The workshop will focus on practical aspects about how to diagnose etiologically, type I and type IV hypersensitivity in cutaneous inmunoallergic diseases, including the differential diagnosis of inducible chronic urticaria and environmental induced dermatitis exacerbations in atopic patients.
At the end of the workshop the attendant should know how to prescribe and perform the following diagnostic tests for chronic urticaria, immediate contact dermatitis and delayed contact dermatitis:
1) Use of the provocation tests to distinguish the types of inducible urticarias and know differential diagnosis with other dermatological conditions,
2) Perform the cutaneous provocation test according to the protocols, which are necessary for the identification of inducible urticaria and that allow the assessment of its severity by looking for useful thresholds in e.g cold, solar, cholinergic and other forms of inducible urticaria,
3) Assessment of disease control of the chronic inducible urticaria during the treatment by using an specific validated questionnaire,
4) To decide when to prescribe and test patients, to distinguish the types of immediate contact skin reaction and differential diagnosis with other dermatological conditions,
5) Decide and perform the provocation test, which is necessary to do the etiology diagnosis of immediate contact skin reaction such as contact urticaria or protein contact dermatitis, such as prick testing and others,
6) Identify types of delayed contact dermatitis, eczematous or not, and differential diagnosis,
7) Be familiar with indications and contraindications for patch testing,
8) Know how to perform patch test, semi-open/open-test and ROAT and evaluate the relevance of a positive reaction,
9) Take preventive measures of a positive patch test.
