Description of intervention(s) / exposure
Wegener's granulomatosis is an inflammatory disorder of the blood vessels. The cause of this condition is unknown. However, involvement of the upper airways and lungs suggests inhaled substances may have a role.
All cases and controls will undergo a detailed standarised interview regarding environmental exposures prior to the onset of the Wegeners (Cases) or at a matched time point for the controls. The interview will be done once only and will take 1 hour
