BACKGROUND Standardized proportionate mortality ratio (SPMR) was found to be 2.2 (95% CI = 1.3-3.5) for esophageal cancer (EC) among workers exposed to refractory brick dust in a large iron-steel complex in China. METHODS A nested case-control design within a cohort of industrial workers. One hundred and twenty-five EC cases and 250 controls were(More)
There have long been case reports linking silica exposure to a variety of autoimmune diseases (systemic sclerosis, rheumatoid arthritis, lupus, chronic renal disease). Evidence of this association in larger epidemiologic studies has been increasing in the last decade. We summarize this evidence here, and present some plausible mechanisms which have been(More)
Occupational exposure to wood dusts has been well established as a cause of nasal cancer, dermatitis, and pneumonites from molds growing in wood chips. With the exception of studies on western red cedar asthma, there is a dearth of information on the respiratory toxicity of wood dust exposure. This paper reviews the clinical and epidemiologic literature and(More)
Intraoperative nerve monitoring (IONM) is a safe technique that is of clear clinical value in the preservation of cranial nerves in skull base surgery and is rapidly becoming the standard of care. Available nerve monitoring systems vary widely in capabilities and costs. A well-informed surgeon may best decide on monitoring needs based on surgical case(More)
Risk of epithelial ovarian cancer (EOC) attendant to use of hormone replacement therapy (HRT) was evaluated in a population-based case-control study of newly diagnosed EOC cases (n=256) and randomly selected population controls (n=1122). Telephone interviews were conducted to obtain information on history of HRT and several other covariates. Multivariate(More)
We compared measurements of urinary alkylphosphate metabolites and oxime-induced reactivation of plasma cholinesterase (P-ChE) and erythrocyte acetylcholinesterase (RBC-AChE) with measurements of foliar residues, skin and clothing contamination, and P-ChE and RBC-AChE activities among 20 Northern California peach orchard workers exposed to the(More)
We conducted a cross-sectional investigation to determine whether table grape harvesters, who have significant cutaneous contact with crop-associated materials that may cause skin disease, are more likely to develop dermatitis than are a control group of tomato workers performing mechanical harvesting with minimal cutaneous contact with crop-associated(More)
This study was conducted to identify barriers to cancer prevention and evaluate the effectiveness of a cancer prevention project to increase screening for cervical and breast cancer among Spanish-speaking farmworkers in California's Central Valley. Bilingual health educators met with farmworker communities near Merced and Modesto, CA, to determine barriers(More)
When cancer is possibly related to occupation, the family physician's task is to put the matter in perspective by educating the patient and carefully documenting the appearance of the tumor and the patient's work history. Occasionally, physicians are the first to recognize new associations between chemicals and cancer and can help to bring hazards under(More)
Rice farmers are occupationally exposed to agents that may affect respiratory health, including inorganic dusts and smoke from burning of agricultural waste. To assess respiratory health of this occupational group, we conducted a cross-sectional study, including a self-administered health and work questionnaire, spirometry, and chest radiography among 464(More)
