Given that criteria for nasal surgery in individuals with obstructive sleep apnea syndrome (OSAS) have not been proposed, we investigated the effectiveness of nasal surgery for CPAP failure in patients with both severe OSAS and nasal obstruction. ⋯ Increased nasal resistance is a determinant of CPAP failure, and the surgical correction of severe nasal obstruction should thus be considered to facilitate treatment of OSAS patients with CPAP.

The incidence of Japanese cedar pollinosis is estimated to be about 13% of the Japanese population. In Japan it is generic to wear a facemask and eyeglasses to prevent pollen inhalation. We examined the usefulness of a facemask and eyeglasses in cooperation with volunteers. ⋯ The pollen invasion rate in the nasal cavity and on the conjunctiva was increased with increases in the wind speed. It may be difficult to avoid pollen even when wearing a facemask and eyeglasses when the wind speed is high. Further study is required to clarify the relationship between the amount of allergens and clinical symptoms.
