ABSTRACT

The exhaled air of healthy people contains nitric oxide.Under the physiological condition, nasal nitric oxide(NNO) comes primarily from the sinuses, a little is produced in the nasal mucosa.Fractional exhaled nitric oxide is mainly from the trachea and bronchus.When airway diseases occur, it can influence the concentration of exhaled nitric oxide.Therefore, with the continuous improvement of technology in recent years, the measurement of NNO has been widely used in upper airway diseases of children.It is characteristics of quantitative, non-invasive, simple and safe.This article reviews the measurement methods of NNO and its clinical application in children upper airway diseases such as rhinitis, sinusitis, nasal polyps and adenoid hypertrophy.

ABSTRACT

Once released into the air, humidifier disinfectants became tiny nano-size particles, and resulted in chemical bronchoalveolitis. Families had lost their most beloved members, and even some of them became broken. Based on an estimate of two million potential victims who had experienced adverse effects from the use of humidifier disinfectants, we can say that what we have observed was only the tip of the iceberg. Problems of entire airways, as well as other systemic effects, should be examined, as we know these nano-size particles can irritate cell membranes and migrate into systemic circulation. The story of humidifier disinfectant is not finished yet.
