Exogenous Dermatoses presents a collection of comprehensive essays written by experts scientifically active in exogenous dermatoses research. Main areas covered include basic biological mechanisms, diagnostic methods, experimental investigations, and clinical aspects. The book will be an important source of reference for clinical and experimental dermatologists and scientists working with skin immunology and toxicology. It will also provide important information for cosmetic and pharmaceutical research.

Environmental Dermatitis

Exogenous Dermatoses

This authoritative and well-researched Second Edition covers everything from classification and immunology of the basic mechanism of eczema reaction, to clinical types (particularly irritant, allergic, atopic, and hyperkeratotic hand eczema), epidemiology, occupational aspects, and treatment modalities. The new information information on risk factors and chapters on toxicological and clinical aspects.

It is an unusual event for a textbook covering such a national and international networks and the use of highly specialized field as contact dermatitis to be standardized methodology, a highly differentiated published in its fourth edition within a time period picture can now be painted; we know the major p- of 13 years. When the European and Environmental fessions at risk, as well as the influences of age and Contact Dermatitis Research Group was founded in various cofactors. This is a solid basis for preventive 1985,one of the major goals was to edit a textbook of measures. A new allergen, described in one center, high scientific standard written by renown experts can now be tested on a large scale in a short time and keep it regularly updated. The greatest danger period. If the data evaluation shows an unacceptably for a textbook is to become outdated – then it stays high rate of sensitization in the exposed population, on the bookshelf and is rarely consulted. The contin- regulatory measures will be undertaken to protect uous flow of new medicaments, the fascinating the consumer. A recent example is the “methyldib- improvements in diagnostic image analysis and ever- mo glutaronitrile story. ” changing operative procedures are the reasons for These and other issues of importance are covered considerable knowledge deficits in old textbooks, in depth in the newest edition of this textbook.

Contact Dermatitis

This publication serves as a guide to medical doctors and dentists in the evaluation and management of problems related to nickel allergy. The chemistry, analysis, and monitoring of nickel is explored. Recent advances in the immunology of nickel are dis-cussed. Additionally, sensitization assays for both humans and animals are presented. The clinical, genetic, and epidemiologic as-pects of nickel sensitization and nickel dermatitis are explained. Social and demographic aspects of nickel contact allergy are dis-cussed, as well as the topic of the nickel dermatitis as a pre-ventable health problem.

10. 1. 1. 1 The Purpose of Patch Testing Patch testing is a well-established method of diagnosing allergic contact dermatitis, a delayed type of hypersensitivity (type IV reaction). Patients with a history and clinical picture of contact dermatitis are reexposed to the suspected allergens under controlled conditions to verify the diagnosis. Besides testing patients with hand, arm, face or leg eczema (stasis dermatitis), testing of other types of eczema (atopic, seborrhoeic dermatitis, nummular eczema) is sometimes indicated, especially when the dermatologist suspects contact allergy to prescribed topical medicaments and their vehicles. Apart from its use to confirm a suspected allergic contact dermatitis, the patch test procedure can also be used before recommending alternative corti costeroids, skin care products, cosmetics, gloves, etc. in a particular patient. If the patient does not react to the alternatives tested, it is very unlikely that she or he will react to the products in ordinary use. 10. 1. 1.2 Standardization The first patch tests according to present principles were carried out in 1895 [1], but were preceded by some preliminary experiments [2] (see Chap. 1).

Ideally every patient with eczema should be patch tested and the importance of this investigation is now universally accepted. The simplicity of the technique belies its many pitfalls, the greatest being to lack the knowledge required to select the correct allergens and to interpret the results. The introduction, nearly 20 years ago, of the journal Contact Dermatitis greatly stimulated the reporting of the clinical side of contact dermatitis but a vast amount of laboratory work has also been published in other journals on the mechanisms and theory of these reactions. The literature on the subject is now quite vast and a comprehensive book on the clinical and research aspects of contact dermatitis has been sorely needed. This textbook was carefully planned to gather together what is known of the subject into a cohesive whole and it has succeeded admirably. It consists of 22 chapters written by 41 contributors, each selected for their special study of particular subjects. Every feature of contact dermatitis has been covered, beginning with its history and even concluding with the names and addresses of those worldwide who have a specific interest in the subject. The text is illustrated and well laid out; it has been broken up into clearly demarcated sections making it easy to read and its information readily accessible. One's own writing concentrates the mind but editing the texts of authors from so many different countries was a task of considerable proportions.
