About the author

Anton C. de Groot

Anton C. de Groot (1951) has followed his dermatology training in Groningen, The Netherlands, from 1976-1980. After obtaining his license, he has practiced dermatology in the Willem-Alexander Hospital and Carolus-Liduina Hospital in 's-Hertogenbosch, The Netherlands. For 5 years he has served as the Chairman of the Board of the Medical Staff.

Adverse reactions to drugs

De Groot became interested in the subject of adverse reactions to drugs after having followed an internschip with prof. Andrew Herxheimer, a dermatologist and pharmacologist in London, from september to december 1975. This lead to his first (co-authored) publication: Herxheimer A, de Groot AC. Some effects of injected hyoscine butylbromide: a versatile class experiment in human pharmacology. Brit J Clin Pharmacol 1977;4:337-342

Meyler's Side Effects of Drugs

Chapters in the Meyler's Side Effects of Drugs series

From 1980 to 2000, he contributed, in the beginning with prof. Johan Nater from Groningen, to the well-known Elsevier series "Meyler's Side Effects of Drugs" (Meyler was a pharmacology professor in Groningen). His first Chapter was in the 1980 9th Edition of 'Meyler' and the coverage was limited to 'Drugs used on the skin'. In the 14th Edition, twenty years later, the chapter had been expanded to 'Dermatological drugs, topical agents and Cosmetics'. In this period, 19 yearly 'Side effects of Drugs Annuals' were published each containing his chapter with updates of the relevant literature from the previous year.

First book: 'Unwanted Effects of Cosmetics and Drugs used in Dermatology'

Meanwhile, his interest in adverse reactions to drugs and cosmetics had resulted in the publication of a book on this subject (separate from the Meyler series) titled Unwanted Effects of Cosmetics and Drugs used in Dermatology. The first Edition, which was written in cooperation with Johan Nater, appeared in 1983, already two years later followed by a vastly expanded second edition.

The third edition in 1994 finalized this series. At this time the literature on this broad subject had become so elaborate, that it was impossible to have the book keep its encyclopedic character. Also, at that time the booming digital possibilities to search the medical literature decreased the need for such encyclopedic reference works.

Thesis: Adverse Reactions to Cosmetics

In the same period, in 1988, De Groot wrote his PhD Thesis on - not quite unexpectedly - the subject Adverse Reactions to Cosmetics. He was one of the first to see the dangers of the cosmetic preservative methylisothiazolinone + methylchloroisothiazolinone (at that time invariably indicated with its trade name Kathon CG) and invited his friend and former teacher Andrew Herxheimer to co-author an article on the 'epidemic' of contact allergy to this biocide in The Lancet: De Groot AC, Herxheimer A. Isothiazolinone preservative: cause of a continuing epidemic of cosmetic dermatitis. The Lancet 1989;i:314-316. Previously, their cooperation already had resulted in another publication in The Lancet, about the very limited efficacy of minoxidil in the treatment of male pattern alopecia: De Groot AC, Nater JP, Herxheimer A. Minoxidil: hope for the bald? The Lancet 1987; i: 1019-1022
