Thaumatin is a sweetener and flavor modifier commonly used in the food industry. Likewise, gum arabic is widely used as a food stabilizer and thickening agent. We report here that a powder mixture composed of 10% thaumatin and 90% gum arabic led to allergic symptoms in the upper airways in occupationally exposed individuals: four of eight workers of a chewing gum factory exposed to this powder mixture had pronounced rhinitis. A positive skin prick test result for pure thaumatin was obtained in…

Cytopathology of the Nasal Mucosa in Smokers: A Possible Biomarker of Air Pollution?
As yet, no significant relation between smoking habits and the incidence of nasal sinus squamous cell carcinomas has been demonstrated in contrast to the established relationship between smoking and carcinomas of the larynx and lungs, so it is conceivable that cytopathologic changes in the nasal mucosa could act as a biomarker reflecting similarChanges in the lower respiratory tract.
