Study participants are going to be interviewed by the investigators about impairment in QOL of their illnesses. Two separate questionnaires are going to be filled in by each participant. For measurement of general QOL, the widely used SF-12 questionnaire (8 questions) is going to be used. To measure specific impairment in QOL by dermatologic disease, participants are going to be asked to fill in the DLQI (Dermatology life quality index, 10 questions). Photographic documentation of specific identified lesions will be made and pictures stored exclusively in the secured electronic patient file (KISIM). Medication and all identified diseases will be noted. All diagnostically useful information is going to be recorded in the patient file and transmitted to the referring physician in the discharge letter.
