The main variable was time first return to work. Subjects followed up at 1, 3 6 months after initial interview. Cox proportional hazards model used analyse associations between potential predictors...

OBJECTIVES: To determine if there is an increased risk of admission to hospital for various diseases among vinyl chloride monomer (VCM) workers. METHODS: 2224 workers with occupational exposure VCM were identified occurrence disease based on a search computer files labour insurance. These data compared those manufacturing optical equipment and motorcycles from 1 January 1985 31 March 1994. Cardiovascular cerebrovascular used as reference diseases, the age adjusted morbidity odds ratio (MOR)...

To determine the standardised mortality ratio (SMR) corresponding to different causes of death in workers from polyvinyl chloride polymerisation factories Taiwan.Retrospective cohort study six Taiwan. A total 3293 male who had been employed for at least one year during period 1 January 1950 31 December 1992, and were alive on 1985 included analysis. Using data acquired Taiwan's National Mortality Registry, it was found that 144 these died 1985-97. The follow up rate 99% with a number...

To investigate relevant aspects of functioning and disability, environmental factors in people with adolescent idiopathic scoliosis according to patients' self-reports based on the International Classification Functioning, Disability Health for Children Youth (ICF-CY).Multicentre, empirical, cross-sectional study.Four departments orthopaedics 4 hospitals, 5 rehabilitation medicine hospitals.Semi-structured interviews were conducted 975 patients from hospitals self-reporting. In addition,...

The questionnaire of occupational stress index (OSI) has been popular in the workplace, and it tailored for bus drivers Taiwan. Nevertheless, its outcomes participants are based on self-evaluations, thus validation by their physiological biomarker is warranted this main goal study.A cross-sectional study sixty-three city fifty-four supporting staffs comparison was conducted. Questionnaire surveys, 24-hour urine cortisol testing, blood draws dehydroepiandrosterone-sulfate (DHEA-S) testing...

Learning Objectives Identify previously reported findings relating occupational vinyl chloride monomer (VCM) exposure to liver disease. Relate how - and what extent hepatitis B surface antigen (HBsAg) status particular job-related tasks interact increase the risk of hepatocellular carcinoma in workers exposed VCM. Explain postulated mechanisms by which virus infection VCM may cause cancer. Vinyl-chloride (VCM), a human carcinogen, has caused angiosarcoma liver. Recent studies have shown that...

To investigate types of cancer caused by occupational exposure to vinyl chloride monomer (VCM) and the temporal mortality trends these cancers in workers from polyvinyl (PVC) manufacturing factories Taiwan, with follow-up cohort extended 15 years, 1980 2007. Methods A retrospective study six PVC Taiwan was conducted. 3336 male were enrolled further linked National Mortality Registry Household databases. Standardised ratios (SMR) 95% CIs calculated compared general Taiwanese population....

Objectives: To determine the association between printing works and nasopharygeal carcinoma as well other diseases. Methods: Demographic data were obtained for those who had worked in a particular newspaper company since its establishment 1950. Through access to bank of hospital records Labor Insurance Bureau 1985–94, all workers identified been admitted during their employment company. Multiple logistic regressions performed estimate adjusted morbidity odds ratio (OR) various diseases among...

Expanded perlite has been assumed as simple nuisance, however during an accidental spill out in Taiwan, among 24 exposed workers followed for more than 6 months, three developed persisted respiratory symptoms and positive provocation tests were compatible with reactive airway dysfunction syndrome. During simulation experiment expanded is shown to be very dusty greatly exceed current exposure permission level. Review of literature evidence, though below level may generally safe, precautionary...

Vinyl chloride (VC) workers are known to be at risk for development of angiosarcoma the liver (ASL), a rare tumor. Previously, study p53 gene mutations in tumors VC-exposed found that 50% angiosarcomas contained such mutations. Mutant oncoprotein and anti-p53 antibodies can also sera ASL patients without cancer. Workers Taiwan have been exposed VC, some contracted tumors. In this study, we used enzyme-linked immunosorbent assays detect mutant protein plasma Taiwan. Thirty-three 251 (13.2%)...

We investigated whether exposure to ethylene dichloride (EDC) and vinyl chloride monomer (VCM) resulted in increased risk of liver damage. Epidemiological information, including occupational, medical, smoking, drinking history, was obtained by interview from 251 male workers. Serum alanine aminotransferase (ALT), aspartate (AST), γ-glutamyltransferase (GGT) were used as indicators Exposure moderate or low levels ECD VCM a higher developing abnormal ALT than did lower the chemicals. Results...

Background: Underreporting occupational disease cases has been a long-standing problem in Taiwan, which hinders the progress health and safety. To address this problem, government founded Network of Occupational Diseases Injuries Service (NODIS) for injury services established new Internet-based reporting system.Objectives: The aims study are to analyze possible influence NODIS, comprised Center Disease Injury Services their local network hospitals, on compensable diseases describe...

Vinyl chloride (VC) workers are known to be at risk for development of liver angiosarcoma, a rare tumor. Previously, more than 80% VC with angiosarcoma have been found an Asp-13 c-Ki-ras oncogene mutation, and 50% VC-exposed without tumors were Asp13-Ki-ras oncoprotein in their plasma. Some Taiwan had also exposed VC, some contracted tumors. In this study, we used enhanced chemiluminescence Western blotting detect Asp13-p21-Ki-ras the sera Taiwan. There 14 113 (12.4%) positive plasma, but 0...

The objective of this study was to evaluate ultrastructural changes epidermal nerve density (END) in workers exposed hand-transmitted vibration.Ten male subjects with occupational exposure tools for 46.9 hours weekly an average 6.5 years were included study. We performed a skin biopsy from the forearms and compared END 10 age- gender-matched healthy control subjects.Nine had abnormally low END. significantly lower than group (4.1 +/- 2.8 vs 9.0 4.3 fibers/mm, P = 0.005). difference remained...

Abstract The use of molecular biomarkers in epidemiologic studies has been advancedas a way to improve risk assessments for occupational and environmental exposuresto toxic agents. We have used the detection two cancer-related, vinyl chloride exposure (mutant ras-p21 mutant p53) examine workers with equivalent cumulative exposures that would be above or below current permissible workplace limit differences presence these biomarkers. Workers (equivalent > 40 ppm-years) statistically...
