The prevalence of active and inactive peptic ulcer was 23% in male workers aged 31-60 at a plastics processing factory in Tokyo. Similarly, the incidence of active and inactive peptic ulcer during one year was 5% or more. The findings from a case control study suggested that smoking and family history were the major aetiological factors. The incidence and prevalence of peptic ulcer in male fact...

Introduction: Noise, as the most common pollutant in the industrial environment, can lead to hearing loss and negatively affect other organs such as the cardiovascular system. Cigarette smoking is a popular habit among some workers, and can also have a negative effect on the cardiovascular system. This study aimed to investigate the effect of simultaneous exposure to noise and cigarette smoke o...

BACKGROUND The prevalence and incidence of syphilis infection were examined in a cohort study of factory workers in Ethiopia. METHOD Between February 1997 and March 1999, 409 men and 348 women were enrolled and followed in the cohort study. RESULTS The prevalence (95% CI) of past/current syphilis (positive TPPA serology) was 28.9% (25.7% to 32.3%), and factors associated with past/current s...

Were ordinary factory workers unskilled and was technology “de-skilling” during the Industrial Revolution? I measure foregone output to estimate the human capital investments in mule spinners and power loom tenders in ante-bellum Lowell. These investments rivaled those of craft apprentices. Although factory workers were unskilled in a sense, the implementation of this technology depended on the...

Two summer outbreaks of humidifier fever (HF) are described in a microprocessor factory (factory A) and a printing factory (factory B). The air in each factory was humidified intermittently and controlled by present humidistats operating to maintain a relative humidity of 45% by an air handler incorporating a spray humidifier in factory A and two ceiling mounted spray humidifiers in factory B. ...

We examined sister chromatid exchanges (SCEs) and micronuclei (MN; cytokinesis-block method) in cultured peripheral lymphocytes from 52 female workers of two shoe factories and from 36 unexposed age- and sex-matched referents. The factory workers showed an elevated level of urinary hippuric acid, a biomarker of toluene exposure, and workplace air contained high concentrations of various organic...

background solvents such as benzene and toluene are commonly used in tire manufacturing, and significant occupational exposure to these chemicals adversely affects the health of workers. in biological monitoring, a complementary method for personal monitoring, the internal absorbed dose is measured and individual, environmental, and exposure differences are taken into consideration. conclusions...
