- OBJECTIVES
To confirm the HAVS in workers exposed to hand-arm vibration with using the objective diagnostic methods METHODS: Several tests were used to help substantiate a clinical diagnosis of HAVS. Some other diseases were excluded by a medical interview, hematologic assessment, urinalysis, X-rays. The hand-arm vibration acceleration level of the grinder was evaluated for considering HAVS.
Peripheral vascular changes were examined by a cold provocation test. An electromyography was implemented to ascertain the peripheral neural changes.
RESULTS
8 workers with symptoms in hands & fingers, exposed to hand-arm vibration were examined. Some other diseases(primary Raynauds disease, secondary Raynauds disease in not occupational origin) were excluded by a medical interview, hematologic assessment, urinalysis, X-rays. The hand-arm vibration acceleration level of the grinder was 7. 9 m/sec2. The recovery time of a skin temperature followed finger cooling was significantly prolonged in 6 workers with HAVS. The nerve conduction velocity was reduced in 6 workers with HAVS.
CONCLUSIONS
So we report 6 cases of HAVS in grinding workers exposed to hand-arm vibration diagnosed objectively by an exclusion of some other disease, handarm vibration acceleration level, cold provocation test, electromyography.

- OBJECTIVES
The increased prevalence of asthma over the last 30 years has been reported from many different countries, including Korea. The increased prevalence may be due to increased exposure to indoor air pollutants.
METHODS
In this study, the relationship between residential environments and airway hyper-responsiveness has been examined among 280 family members. The bronchial hyper-responsiveness was expressed as the log-transformed slope of FEV decrease over the log-transformed dose of methacholine concentration(BRindex). Simple regression analysis was done for the effect of sex, age, atopic status, and residential environments including active and passive smoking exposures on airway responsiveness. Based on simple regression results, multiple rwegression analysis was performed for total group and also according to sex.
RESULTS
The mean of BRindex of residents living in gas boiler heating houses was higher than that of central heating system (p=0.014). Smoking status was a significant determinant of bronchial hyper-responsiveness in both genders; male(p=0.017), female (p%.022). In the male group the mean of BRindex of current smokers was significantly higher than those of ex-smokers and non-smokers, and the mean of BRindex of passive smokers was higher than that of non-smokers, but statistical significance was border-line(p=0.069). In female group, the mean of BRindex of kerosene stove users was higher than that of non-users(p=0.057).
CONCLUSIONS
This study suggests that indoor air pollutants including type of heating, passive smoking and kerosene stove use can contribute to the increase in asthma prevalence in Korea.
