The risk factors for occupational contact dermatitis among workers in a medium density fiberboard furniture factory in Eastern Thailand.

The aim of this study was to determine the occupational exposure to formaldehyde on the medium-density fiberboard (MDF) dust and allergic contact dermatitis among the workers at a furniture factory. Data were collected from 439 subjects using questionnaires and patch testing to evaluate allergic contact dermatitis resulting from formaldehyde on wood dust exposure in the workplace. The geometric mean concentration of formaldehyde on MDF dust that the workers in the production department were exposed to was 2.

Respiratory Symptoms due to Occupational Exposure to Formaldehyde and MDF Dust in a MDF Furniture Factory in Eastern Thailand.

The study aimed to investigate factors associated with respiratory symptoms in workers in a medium-density fiberboard (MDF) furniture factory in Eastern Thailand. Data were collected from 439 employees exposed to formaldehyde and MDF dust using questionnaire and personal sampler (Institute of Occupational Medicine; IOM). The average concentration of formaldehyde from MDF dust was 2.

Neuropsychological Symptoms among Workers Exposed to Toluene and Xylene in Two Paint Manufacturing Factories in Eastern Thailand.

The study analyzed the exposure factors that may lead to neuropsychological symptoms among 92 workers who were exposed to xylene and toluene and 100 workers who were not exposed to the solvents. The airborne concentration of xylene and toluene was evaluated with personal passive badges. The levels of methyl hippuric acid and hippuric acid in urine were assessed, and interviews were performed to observe the neuropsychological symptoms that may result from exposure to the solvents.

Semi-quantitative exposure assessment of occupational exposure to wood dust and nasopharyngeal cancer risk.

Occupational exposure to wood dust is one cause of nasopharyngeal cancer (NPC); however, assessing this exposure remains problematic. Therefore, the objective of this study was to develop a semi-quantitative exposure assessment method and then utilize it to evaluate the association between occupational exposure to wood dust and the development of NPC. In addition, variations in risk by histology were examined.

Cold exposure and health effects among frozen food processing workers in eastern Thailand.

Frozen food processing workers work under a cold environment which can cause several adverse health effects.This study explored factors affecting workers' health in the frozen food industry in Thailand. Participants comprised 497 workers exposed to a cold working environment and 255 office workers who served as the controls.

Evaluation of non-viral risk factors for nasopharyngeal carcinoma in Thailand: results from a case-control study.

Nasopharyngeal cancer (NPC) is rare in most populations but common in Southern China and Southeast Asia. To understand the role of environmental exposures on risk of NPC, a case-control study was conducted among 327 newly diagnosed case of NPC and 327 controls matched to case on sex, age and geographic residence. Information was collected by interviewer about demographic variables, cigarette smoking, alcohol drinking, eating habits, past history of disease, family history of cancer and a lifetime history of every job that was held for one year or longer.
