ABSTRACT
The first step in the diagnosis of sick-house syndrome (SHS) and chemical sensitivity (CS) begins with determining the etiological factor. Before examining a patient, doctors in the Kitasato University clinic send an interview sheet including 11 pages of the Quick Environmental Exposure and Sensitivity Inventory (QEESI®) by C. S. Miller [1]. The questionnaire includes the history of local and systematic allergy, medical treatment in dental procedures, occupation, birthplace, relocation and reconstruction/modification, living environment, the medicines used, food, luxury goods, and so forth. Ishikawa partly modified this questionnaire into the Japanese language and examined CS cases. Those studies showed similar results in the symptoms between US and Japanese patients [2].
