{ "abstract": "The present guideline updates the initial ESCD patch testing guideline, summarizing all aspects of patch testing for the diagnosis of contact allergy in patients suspected of suffering, or having been suffering, from allergic contact dermatitis or other delayed-type hypersensitivity skin and mucosal conditions. Sections with brief descriptions and discussions of different pertinent topics are followed by highlighted short practical recommendations, which have been consensualized in a Delphi process. Topics comprise, after an introduction with important definitions, materials, technique, modifications of epicutaneous testing, individual factors influencing the patch test outcome or necessitating special considerations, children, patients with occupational contact dermatitis and drug eruptions as special groups, patch testing of materials brought in by the patient, adverse effects of patch testing and the final evaluation and patient counselling based on this judgement. Finally, short reference is made to aspects of (continuing) medical education and to electronic collection of data for epidemiological surveillance.", "abstract_shown": true, "affiliations": [ "Department of Medical Informatics, Biometry and Epidemiology Friedrich‐Alexander Universität Erlangen/Nürnberg Erlangen Germany", "University Hospital Antwerp (UZA) and University of Antwerp Antwerp Belgium", "Department of Dermatology, Bispebjerg Hospital University of Copenhagen Copenhagen Denmark", "Department of Dermatology, Environmental Medicine and Health Theory Osnabrück University Osnabrück Germany", "Institute for Interdisciplinary Dermatologic Prevention and Rehabilitation (iDerm) Osnabrück University Osnabrück Germany", "Department of Occupational and Environmental Dermatology, Lund University Skåne University Hospital Malmö Sweden", "Contact Dermatitis and Occupational Dermatoses, Hospital de Clínicas “José de San Martín” Buenos Aires University Buenos Aires Argentina", "Department of Occupational and Envionmental Diseases, University Hospital of Centre of Paris, Hotel‐Dieu Hospital, AP‐HP, and Department of Dermatology University Hospital of Centre of Paris, Cochin Hospital Paris France", "Department of Dermatology, Hospital del Mar Research Institute Universitat Pompeu Fabra Barcelona Spain", "Clinic of Dermatology, University Hospital, Coimbra Local Health Unit and Faculty of Medicine University of Coimbra Coimbra Portugal", "Faculty of Medicine Catholic University of Leuven (KU Leuven) Leuven Belgium", "Institute of Environmental Medicine Karolinska Institutet Stockholm Sweden", "Department of Dermatology and Venereology, University of Zagreb School of Medicine University Hospital Center Zagreb Zagreb Croatia", "Allergology Division, Paul‐Ehrlich‐Institut Langen Germany", "Department of Dermatology at Norrlands University Hospital Umeå Umeå Sweden", "Department of Dermatology at University Hospital of Örebro Örebro Sweden", "Department of Dermatology and Venereology, Istanbul Faculty of Medicine Istanbul University Istanbul Turkey", "Finnish Institute of Occupational Health, Occupational Medicine Helsinki Finland", "Department of Dermatology Montpellier University Hospital and Montpellier University Montpellier France", "Department of Dermatology‐Allergology and Occupational Dermatology Amsterdam University Medical Centers Amsterdam the Netherlands", "Department of Experimental Dermatology and Cosmetology Jagiellonian University Medical College, Krakow, Poland and Instytut Dermatologii Krakow Poland", "Section of Dermatology, Department of Medicine and Surgery University of Perugia Perugia Italy", "Department of Cutaneous Allergy St. John's Institute of Dermatology, Guy's Hospital London UK", "Leeds Teaching Hospitals NHS Trust Leeds UK", "National Allergy Research Centre, Department of Skin and Allergy University of Copenhagen, Gentofte Hospital Copenhagen Denmark" ], "article_type": null, "arxiv": null, "author_total": 24, "authors": [ { "affs": [ 0 ], "name": "Wolfgang J.
