Sjögren's syndrome in the community: can serology replace salivary gland biopsy?
These findings tend to support the suggestion that a patient suspected to suffer from SS in a community setting may be first tested for the presence of anti-Ro/La antibodies to confirm the diagnosis. Only those with a negative result for the presence of anti-Ro/La antibodies need to be referred for salivary gland biopsy.
The Cruciferous Vegetable FFQ provided a reproducible, valid estimate of cruciferous vegetable exposure and improved the relationship between crucifer consumption and urinary dithiocarbamate, a biomarker of cruciferous vegetable exposure. The nearly twofold difference in exposure estimates between the Cruciferous Vegetable FFQ and the standard FFQ could change the statistical significance of risk estimates in the context of epidemiological research. This questionnaire is an appropriate research tool to evaluate cruciferous vegetable intake more accurately than a standard FFQ, particularly in the context of dietary intervention studies that promote increased vegetable intake to reduce the risk for chronic disease.
