Abstract
• Children with frequent recurrent respiratory tract infections and constant mucopurulent secretion from the nose were thoroughly examined, including bacteriologic and immunologic analyses. Biopsy specimens from the nasal mucosa were investigated by light and electron microscopy. Eight different histopathologic factors were distinguished and evaluated in relation to the continual nasal discharge. The mucus production was increased, due to an increased number of goblet cells or submucosal glands. The mucus transport was impaired owing to a decreased number of ciliated cells or different deficiencies in the structure of the cilia. The secretion of periciliary fluid was altered due to dysfunction of microvilliequipped cells and the availability of tissue fluid due to vascular changes. Leakage of tissue fluid partly reflects deficiencies in the epithelial lining. Purulent discharge was observed from microabscesses. Reactive changes in the nasal mucosa are described and discussed in relation to treatment schedules aimed at reducing short- and long-term discomfort and complications.
