[The comparative test of nasal mucociliary function in healthy subjects, smokers and non-smokers]. / Prueba comparativa de función mucociliar nasal en sujetos sanos, fumadores y no fumadores.

Little is known about the changes produced in the nasal respiratory epithelium in individuals with an important smoking habit. The purpose of this study is to compare the nasal mucociliary function in healthy subjects, smokers and non-smokers. The nasal mucociliary transport of aspartame particles was measured in 50 healthy non-smokers and in 50 healthy smokers under similar conditions. The average time taken for the displacement of the test substance from the middle third of the inferior turbinate to the oropharynx was found to be in the smokers 13.62 min., and in the non-smokers, 10.34 min. The results were compared using student's "t" test and a significant difference (p < 0.001) was found between both groups. This result is taken as a simple clinical test that evaluates the smoking effects on the nasal mucociliary function.

Scleroma of the lower respiratory tract: case report and review of literature.

The case of a 46-year-old man who presented with acute respiratory distress due to a tracheal mass is reported. The patient underwent endoscopic resection of the mass and the histopathology revealed scleroma. No other sites of involvement by scleroma were found. This case is reported because laryngotracheal involvement by scleroma as the only manifestation of this disease is extremely rare.
