[Group allergies and multiple reactions in patients with allergy to hydroxyquinoline derivatives].

We carried out patch testing with a chinoline block comprising 25 substances in 316 patients with a suspected allergy to chinoline derivatives in the period from February 1969 to December 1983. 110 patients reacted to 2 or more substances. The reactions were totaled and tabulated in a list indicating frequency of sensitisation as decreasing in the order of Cl-F-Br-I halogens.

[Allergies to 8-hydroxyquinoline derivatives].

Evaluation of our standardized test results from 1972 to 1983 indicated Vioform allergies in 1.2% of all cases and Sterosan allergies in 1.1%.

[Metal allergies. Results of patch tests from 1981 to 1984].

From 1981 to 1984 987 patients of the Allergy Department of the Würzburg University Dermatological Hospital were evaluated with patch testing using a standard series; 199 patients were additionally tested with a specially composed metal battery. The results of the standard series with regard to the four metals contained in it, namely mercuric chloride, nickel sulphate, cobalt sulphate and potassium bichromate, were contrasted with the test results of the metal battery. Here there were conspicuous discrepancies between the two collectives, above all, with respect to cobalt.

Patch testing in children (II). Results and case reports.

The results of 10 years of patch testing in children aged 3-16 years are reported. The commonest allergens found were nickel, cobalt, para-dyes and chromate. 26 cases are recorded in detail.

Patch testing in children. (I) Collective test results; skin testability in children.

The results of 10 years of patch tests in children with eczema aged between 3 and 16 years are reported. 147 children were tested, of whom 104 (71%) reacted. 334 (6.

[Contact allergies of the oral mucosa].

Patch tests were performed on 132 patients suspected of allergic sensitivity to dentures. Of these, 98 reacted positively to at least one substance. While only 4 patients showed positive reactions to methyl methacrylate, 42 (31,8%) had positive tests with the catalyst benzoyl peroxide, 4 and 5 patients, respectively, were positive to 4 different inhibitors, 7 patients reacted positively to various softeners and 3 to the reducing agent hydrazine sulfate.

[Insect hyposensitization using whole-body extract].

The following information was obtained through a control of 76 patients allergic to insect bites who were treated with whole body extract (WBE): The reaction to insect sting was light in 11 patients, intermediate in 31, and severe in 28, while 6 patients developed only extreme local reactions. In 17% of the cases, systemic reactions occurred during skin testing. No statistically significant correlation existed between the severity of the reactions to stings in the patients' history and the skin test results, but such a significant correlation could be found between history of sting reactions and serum antibodies.

[Allergic contact eczema to pyridine and hydrazine derivatives].

The case of a chemistry student with a severe bullous, eczematous allergic contact dermatitis and with a diagnosed sensitization towards pyridine and hydrazine derivatives is reported. The results of the group allergy testing are compared with those in the literature and the widespread occurrence of pyridine and hydrazine compounds is summarized in tables.

[Erythrocyte sensitization syndrome (Gardner-Diamond syndrome, Sharp's painful bruising syndrome)].

This article gives a review of the literature dealing with the morphological aspects in erythrocyte sensitization syndrome and presents a patient with typical systemic and skin involvement in whom psychic stress situations play an important role as a trigger mechanism.

[Anaphylactic shock during general anaesthesia due to fentanyl and alloferin in a patient with positive skin test (author's transl)].

A patient who suffered an anaphylactic shock during general anaesthesia showed positive reactions in a skin test with fentanyl (i.e. in Thalamonal) and Alloferin.

[Excessive allergy due to benzoic acid followed by anaphylactic shock. (author's transl)].

The case of a trained chemical worker highly sensitive to benzoic acid is described. He suffered from allergic reactions of increasing intensity while being constantly exposed to benzoic acid during work. After oral exposure to benzoic acid he suffered a severe anaphylactic shock and later on showed similar but milder reactions when eating food containing benzoic acid.

[Allergy to ed-edta and formaldehyde (author's transl)].

1. Comparison of the ED/EDTA allergies as determined by epicutaneous testing from 1977-79 with the test results from 1980. An increase in the sensitization indices for ED as well as for EDTA is evident.

Vitamin C allergy of the delayed type.

A case of vitamin C allergy of the delayed type is reported. Eczematous skin lesions appeared during normal uptake of the vitamin C contained in food. After a vitamin C-free diet, the skin lesions disappeared.

[Pesticide allergy - allergic contact eczema of a vintner (author's transl)].

Professional eczema of a Vintner who proved to be positive in epicutaneaous testing with sensitization to 7 pesticides used in her own vineyard. First documented case of an allergy to parathion. Additional proof of an iatrogenic sensitization to Fenticlor (dioxy-dichlor diphenylsulfid) with group allergy.

[Ethylenediamine allergy].

Evaluation of our Patch-test results from 1977-1979. Proven allergies to ethylene diamine (ED): 2,17%; proven allergies to ethylene diamine tetraacetate (EDTA): 1,7%. Enormous increase of ED-allergies since the first publication 1959 attributed to the following: 1.

[Allergy due to castor bean meal (author's transl)].

A comprehensive review of the literature on allergy due to castor bean is given as it occurs by inhalation of dust particles in the environment of milk working with castor bean. Furthermore it may occur by handling of castor bean and of its expressed residuals after oil production. A case report is presented about a respiratory allergy caused by castor bean meal containing fertilizer used in culturing grass plats.
