[Electronic data processing storage and analysis of allergologic data with reference to epidemiologic and occupational dermatologic aspects]. / EDV-Erfassung und Auswertung allergologischer Daten unter Berücksichtigung epidemiologischer und berufsdermatologischer Aspekte.

At our contact dermatitis clinic the computer program ALLDAT (Allergy Data System) was developed with the opportunity of storing and analysing different patients data and various kinds of test reactions with regard to epidemiology and occupational dermatology. Because of the internal construction of the data base, high flexibility and optimization of storage (2000 patient/year----1 MB) is achieved. Persons without both program and computer experience are able to enter data, perform analysis and view results after a short period of instruction.

[Characteristics of polymorphous light dermatosis--results of a prospective survey and study of 302 affected patients]. / Charakteristika der polymorphen Lichtdermatose--Ergebnisse einer prospektiven Befragung und Untersuchung 302 Betroffener.

In a prospective study on 302 patients (females = 87%), we registered the historical and clinical data of polymorphous light eruption (PLE) and compared our results to similar studies from Finland, Sweden, and the USA. The mean age of onset of the disease was 24.0 years; the average duration time was 10.1 years. We found the following clinical and historical characteristics of PLE: skin types I and II - 49%; positive family history - 29%; latent period between sun exposure and the first skin eruptions - in 39% less than 2 hours, in 5% 3 days and more. Mostly we observed paular eruptions and strong pruritus, and usually the typical body areas were involved (i.e. décolleté, upper and lower arm, thigh, back of the hand, and face). In 64% of the patients who avoided exposure to the sun, the PLE did not continue but less than a week. Our findings may supply a useful tool regarding the diagnosis of ambiguous photodermatoses.
