For diagnosing the hand-arm vibration syndrome, peripheral circulation and sensory tests immersing one hand in cold water at 10 degrees C for 10 min have been performed widely in Japan. The authors investigated the effects of room temperature, seasonal condition and food intake on the test results, especially finger skin temperature. Six healthy males were(More)
For the diagnosis of the hand-arm vibration syndrome, cold-stress tests using different water temperatures and periods of hand immersion have been investigated in Europe, North America, and Japan. In recent years, peripheral circulation and sensory tests, including finger-skin temperature measurement involving immersion of one hand in cold water at 10(More)
To assess the prevalence of cervical spondylosis and musculoskeletal symptoms among coolies a cross-sectional study was performed in Narayangonj City of Bangladesh on a random sample of 98 male coolies, using a questionnaire and the results of cervical spine X-rays. Statistical associations were investigated using the chi-square test. The results show a(More)
OBJECTIVE The purpose of the study was to investigate the trends and regional variations in infant mortality rates in Japan. METHOD The data from 1973 to 1998 analysed in this paper were from the Vital Statistics Division, Ministry of Health, Labor and Welfare of Japan. RESULTS Infant mortality rates declined significantly between 1973 and 1998 in all(More)
This study was designed to assess the influence of an antivibration glove on digital vascular responses in healthy subjects exposed to short-term grasping of a vibrating handle. To measure finger blood flow (FBF) and finger skin temperature (FST) once at the end of every min, a blood flowmeter sensor was attached to the dorsum and a thermistor sensor was(More)
OBJECTIVE To investigate the influence of room temperature on finger blood flow (FBF) change in healthy subjects exposed to short-term grasping of a vibrating handle under different room temperatures. METHODS FBF was measured using a blood flowmeter in six male subjects on the dorsum of the middle phalanx of third finger in both hands once at the end of(More)
To determine whether noise conditions at the workplace are associated with hypertension in Japanese male blue-collar workers, the authors analyzed data obtained in an annual workplace health examination. Two hundred forty-two workers who used ear protectors at their jobs in a paper manufacturing plant served as a noisy workplace group, and 173 individuals(More)
The objective of this cross-sectional comparative study was to assess quality of life (QOL) of arsenicosis patients. A total of 104 arsenicosis patients, 104 arsenic-exposed individuals without arsenicosis (nonpatients), and 104 individuals not exposed to arsenic (controls) were interviewed based on a questionnaire constructed based on the WHOQOL-BREF(More)
OBJECTIVES The aim of the present study was to non-invasively assess autonomic nervous activity, using time- and frequency-domain analyses of heart rate variation (HRV), and to investigate the relationship between indices of HRV and duration of exposure to vibration (DEV), time since retirement from work involving vibration (TR) and time undergoing(More)
