Conclusion: The incidence and intensity of Candida (primarily C. albicans) was greater in OSMF patients than in healthy controls, but these findings were within the normal limit (3-47%). Therefore, Candida may not be an etiologic factor in malignant transformation. However, controversy still exists over whether the chewing of betel quid in cases of OSMF has an inhibitory effect or promotes the ...

Leisure-time physical activity (LTPA) has been closely related to health improvement. The under-appreciation for energy output by nutritionists stems in part from limited data expressed in caloric equivalent. We converted the frequency, duration, and intensity of LTPA, reported from 15,390 adults in the Taiwan National Health Interview Survey 2001, into kilocalories (kcal). Half of Taiwanese ad...

This is an update on cultural and dietary risk factors for oral precancer and cancer. It is an overview on ethnic differences (where possible) and socio-cultural risk factors (tobacco/areca nut/betel quid, alcohol use and dietary factors) in relation to oral precancer and cancer. While studies were from Western countries, India and China, this update also attempts to include and highlight some ...

BACKGROUND Current smokers exhibit a higher rate of betel-quid chewing than non-smokers. However, little is known regarding the extent to which betel-quid chewing may affect attempts to quit smoking and smoking cessation. The aim of the present study is to examine the association between betel-quid chewing and patterns of quitting smoking. Specifically, we explore whether betel-quid chewing is ...

Betel quid (BQ) chewing, a common tradition in tropical areas, often poses a problem during collection and DNA analysis of buccal samples from many indigenous communities for population genetic studies and in forensic analysis of chewed BQ residues. This study evaluated the use of FTA card, a chemically treated filter paper, in collecting buccal samples from long-term BQ users and subsequent PC...
