...Patricia Michell; J.L.M. Hawk; A. Shafrir; Margaret F. Corbett; I.A. Magnus The weal and flare produced by monochromatic irradiation in solar urticaria may be treated as a classical dose-response. This has been used to investigate therapy with H 1 and H 2 antihistamines. The conventional H 1 drug...

...Wakio Torinuki; Hachiro Tagami An 18-year-old man with solar urticaria is described. The action spectrum ranged from 400 to 500 nm. No inhibition spectrum was found, i.e., the wheal that is induced by visible light was not inhibited by immediate pre- or postirradiation of test sites with light...

... case suggests that a trial with H 2 antihistamine should be considered for the treatment of solar urticaria. 10 12 1985 4 06 1986 13 10 2009 © 1986 S. Karger AG, Basel 1986 Copyright / Drug Dosage / Disclaimer Copyright: All rights reserved. No part of this publication may...

...Wakio Torinuki; Norio Kumai; Takashi Miura A 25-year-old man with solar urticaria is described. The action spectrum ranged from 400 to 500 nm. An inhibition spectrum was found to be in the visible light range above 660 nm. Simultaneous or alternate exposure to ‘blue-violet light’ and ‘red light...

...Renato Panizzon A patient is presented with solar urticaria (SU) with an action spectrum of 285–550 nm. The patient showed a positive passive transfer test and a negative reverse passive transfer test. Since such a type of SU is not described in Harber’s classification, we suggest that this patient...

...G. Monfrecola; P. Nappa; D. Pini Three cases of solar urticaria in the visible spectrum successfully treated with astemizole, a H 1 antihistamine, are reported. The administration of 10 mg a day of the drug increased the minimal urticarial dose from 2 to 12 times. 20 02 1989 20 07 1989...

...V. Leenutaphong; E. Hölzle; G. Plewig; B. Kutkuhn; B. Grabensee Three patients with solar urticaria were treated with plasmapheresis. By intradermal injection of in vitro irradiated serum the existence of a circulating photoallergen was demonstrated in cases 1 and 2 but not in case 3...

...R.C. Beljaards; D.P. Bruynzeel We report on a case of solar urticaria with elevated protoporphyrin in the stool. No other evidence for an erythropoietic protoporphyria could be found. 13 06 1990 30 11 1990 8 10 2009 © 1991 S. Karger AG, Basel 1991 Copyright / Drug Dosage...

...H. Miyauchi; T. Horio Background : The action spectrum of solar urticaria varies among cases. In addition, light spectra outside the activating wavelengths can influence the wheal formation in selected patients. Objective : To know the mechanisms of light energy, we examined the effect...

...Y. Kurumaji; M. Shono We describe the first case of drug-induced solar urticaria due to repirinast, an antiallergic drug developed and introduced into the market in Japan in 1987. The patient was a 72-year-old woman who had been on repirinast for 1 year and 8 months. She developed urticaria...

...Laurent Maksimovic; Guillemette Frémont; Michel Jeanmougin; Louis Dubertret; Manuelle Viguier Background: Idiopathic solar urticaria (SU) is a rare type of physical urticaria, occurring immediately after exposure to visible or ultraviolet (UV) light. Treatment is based on sun avoidance and on high...

...M. Watanabe; Y. Matsunaga; I. Katayama Background: Solar urticaria is a rare disorder characterized by pruritus, erythema and wheal upon sunlight exposure. Inhibition spectra (IS), which prevent wheal formation, have been found mainly in Japanese patients and lie mostly in longer wavelengths than...
