Comparative StudyEpidemiology of oral cavity cancer in taiwan with emphasis on the role of betel nut chewing.
This article reports the epidemiological characteristics and the possible contributing etiology of oral cavity cancer in Taiwan. Data on oral cavity cancer from the period between 1986 and 1997 were compiled from the Taiwan Cancer Registry Annual Report. The amount of average annual consumption per person of cigarettes, alcohol and betel nut were extracted from the Annual Report of Taiwan Tobacco and Wine Monopoly Bureau and the Agriculture Counsel of Taiwan. ⋯ Regarding the peak incidence, most cases were seen in the sixth to eighth decades of life. Multiple regression models indicated that 86.2% variation in the incidence of oral cavity cancer was explained by the annual average betel nut consumption per person. These results imply that those who chew betel nut belong to a high-risk group and require special consideration and attention regarding health education and health promotion.

Effectiveness of the jaw-thrust maneuver in opening the airway: a flexible fiberoptic endoscopic study.
A prospective study was carried out to find the exact site of obstruction in sleep model and to quantitatively evaluate the effect of Jaw-thrust maneuver (JTM) in opening the obstructed airway using flexible fiberoptic endoscope. ⋯ Tongue base was the principal site of obstruction although during the respiratory cycle the position of epiglottis changed prominently and increased the obstruction in inspiration. JTM alone significantly relieved the obstruction at the tongue base and epiglottis levels and increased the retroglossal airway.

Evaluation of nasal mucociliary functions with rhinoscintigraphy in coal workers' pneumoconiosis.
To compare nasal mucociliary clearance (NMC) functions in coal workers with pneumoconiosis, coal workers without pneumoconiosis and healthy controls by using technetium-99m-labeled macroaggregated albumin rhinoscintigraphy. ⋯ Our findings demonstrated a synergistic detrimental effect of smoking with coal dust exposure on nasal transport time.
