The aim of this study was to evaluate the validity of a questionnaire and medical anamnesis to identify persons with dermatitis in an occupational setting. The design was a clinical epidemiological cross-sectional study. The study was performed between the second and fourth week of January 2001. A questionnaire was followed a week later by a medical(More)
BACKGROUND Simultaneous contact allergies to the reactive diluent phenyl glycidyl ether (PGE) and epoxy resins based on diglycidyl ether of bisphenol A (DGEBA) or epoxy resins of the bisphenol F-type have been reported. The latter epoxy resins contain three isomers of diglycidyl ether of bisphenol F (DGEBF). PGE, DGEBA, and DGEBF are chemically similar with(More)
In this study, the sensitizing capacities of the 3 main low-molecular-weight isomers of epoxy resins based on diglycidyl ether of biphenol F (DGEBF) were investigated in a guinea pig maximization test (GPMT). The isomers are p,p'-DGEBF, o,p'-DGEBF, and o,o'-DGEBF. The sensitization capacities were compared to diglycidyl ether of bisphenol A (DGEBA), which(More)
BACKGROUND With regard to contact allergy, the dose of a sensitizer per unit skin area is an important factor for both sensitization and elicitation, and therefore a known amount/volume of test preparation should be applied at patch testing. OBJECTIVES To compare three different techniques for the application of aqueous solutions to Finn Chambers, in(More)
BACKGROUND An industry producing rotor blades for wind turbines with an epoxy-based technology had experienced an increasing number of workers with dermatitis, among whom the frequency of occupational contact allergy (OCA) was suspected to be underestimated. OBJECTIVE To investigate the frequency of OCA by patch-testing with a specially profiled(More)
BACKGROUND The currently used patch test concentration of formaldehyde (1.0% aqua; 0.30 mg/cm(2)) has been shown to fail to detect ~ 50% of contact allergies to formaldehyde. OBJECTIVES To justify the inclusion of formaldehyde 2.0% aqua (0.60 mg/cm(2)) in the European baseline patch test series. METHODS A survey of the reported frequencies of contact(More)
BACKGROUND The currently used patch test concentration for formaldehyde is 1.0% (wt/vol) in water. However, clinical experience and previous studies suggest that 1.0% might be insufficient for detecting an optimized number of clinically relevant cases of contact allergy to formaldehyde. OBJECTIVES To validate earlier patch test results for comparison of(More)
Occupational dermatoses were investigated in a factory producing rotor blades for wind turbines by an epoxy-based process. In a blinded study design, 603 workers were first interviewed and thereafter clinically examined. Based on a history of work-related skin disease, clinical findings of dermatitis, or both, 325 (53.9%) of the workers were patch tested(More)
