Erkrankungen durch Phthals�ure und ihre Verbindungen

Epoxy Resins

“…Menschick (1955) and Baader (1955) reported on urticarial reactions in workers in the manufacture of phthalic anhydride. The other case reports describe patients who developed contact urticaria from methylhexahydrophthalic anhydride or methyltetrahydrophthalic anhydride epoxy hardeners from the manufacture of condensers (Jolanki et al 1987b;Jolanki et al 1990), electrical machines (Tarvainen et al 1995a;Kanerva et al 1997), or ski poles (Tarvainen et al 1995a).…”

Occupational contact urticaria caused by cyclic acid anhydrides

“…In the literature, acid anhydride contact urticaria has been described in case reports of single or few patients. Baader and Menschick gave the first reports on urticarial reactions among workers in the production of PA (9, 10). A case of contact urticaria caused by PA was recently described in a refinery worker in Spain (11).…”

Airborne allergic contact urticaria from methylhexahydrophthalic anhydride and hexahydrophthalic anhydride

“…Acid anhydrides induce specific IgE-mediated sensitization (1)(2)(3)(4)(5)(6)(7)(8). Menschick (10) and Baader (11) were the first to report urticarial reactions in workers manufacturing phthalic anhydride. More recently, cases of contact urticaria from MHHPA or MTHPA epoxy hardeners in the manufacture of electrical machines (1, 2), condensers (7,8) and ski poles (1), have been reported (13).…”
