Determination of proliferative activity in nasal polyps.
AIMS To determine the level of proliferative activity in 39 nasal polyps with clear cut distinct clinical behaviour patterns. METHODS The 39 nasal polyps included 11 polyps labelled as "single" and taken from the lateral nasal wall and the middle turbinate; 12 polyps labelled as "massive" and relating to diffuse polyposis involving the entire nasal cavity; six polyps labelled as "ASA" and rel...
متن کامل[Cathepsin D activity in chronic rhinosinusitis with nasal polyps].
UNLABELLED Nasal polyposis affects about 1 to 4% of the population. Polyps develop in oedematous and inflammated mucous membrane. In spite of the intensive research the pathomechanism of their development is not fully understood. The majority of the theories concerning the development of nasal polyps emphasize the role of the inflammatory process causing the rupture of the epithelium and the ba...
متن کاملLysosomal exoglycosidases in nasal polyps.

Up to now the surgical resection is the best method of their treatment, but etiology and pathogenesis of the nasal polyps is not yet fully established.

متن کاملChapter 9 : Nasal polyps
Nasal polyps are an easily recognizable clinical entity. They result from the prolapsed lining of the ethmoid sinuses and block the nose to a variable degree depending on the size. On examination polyps appear as pale bags which arise most commonly from the middle meatus and are relatively insensitive when probed. This helps to differentiate polyps from mucosa of the middle turbinate which may ...
متن کاملEpidemiology of Nasal Polyps
Mounting evidence suggests that nasal polyposis (NP) is a clinical manifestation of multiple possibly coexisting immunologic pathways, and because this entity likely reflects an array of disease states, the epidemiology is difficult to characterize. Phenotypically, chronic rhinosinusitis (CRS) can be classified as either CRS without NP or CRS with NP. CRS without NP, in general, reflects TH1-me...
