[Nasal symptoms in persons with normal nose].
BACKGROUND
Nasal symptoms such as sneezing, stuffy nose and runny nose occur in allergic and nonallergic rhinitis. Normal nose also sometimes has these symptoms. It is necessary to define what is the symptom of normal nose in order to make a proper diagnosis of rhinitis, grading of severity of nasal symptom in rhinitis and criteria of normalization after the treatment of rhinitis.


METHODS
235 persons who had no perceptive nasal symptom and history of nasal disease at present and past, and cold at present, were sampled from the registered list of a health care organization, and examined their nasal symptom by mailing a self-administered questionnaire of nasal symptom. In addition, 54 patients, who visited 4 otolarngology clinics due to diseases other than rhinitis and were diagnosed as normal nose, were examined, using the same questionnaire.


RESULTS
Response rate from persons mailed was 49.8%. Nasal symptom was infrequent in patients at clinic more than persons sampled from the list. Nasal symptom in 117 responders with normal nose had none or occasional and momentary stuffy nose. Sneezing and/or nose blow was less than 5 times a day, and itchy nose and postnasal drip were 30% and 25% respectively. These symptoms, if appeared, were less than 4 days per week.


CONCLUSIONS
Grading "minus", normal, is zero in sneezing and runny nose and none in stuffy nose in the grading system of nasal symptom used commonly in Japan. These should be changed to none or occasional, momentary, easily tolerable in stuffy nose, less than once a day or grading "plus one" (1-5 times per day) occasionally in sneezing and nose blow. Normalization after treatment could be defined according to this change.
