Background -Corticosteroids suppress disease activity in pulmonary sarcoidosis and their use produces symptomatic, radiographic, and functional improvement. There is, however, uncertainty regarding their effects on the overall natural history of the condition and long term benefit is unproven.Methods -Patients with pulmonary radiographic shadowing due to sarcoidosis were recruited in a multicentre study. Those who, in the first six months after entry to the study, neither required prednisolone for symptoms nor showed radiographic improvement were allocated at six months to receive either long term steroid treat-

A sample of 115 urban, working-class, predominantly minority men and women was interviewed by telephone to assess knowledge, beliefs, and barriers relevant to colorectal cancer (CRC) and CRC screening. More than half (53.9%) were unable to name a CRC screening test. Misconceptions were common. Dispelling inaccurate beliefs, establishing an individual's preference for fecal occult blood tests or flexible sigmoidoscopy, and helping individuals take a proactive role in the receipt of CRC screening are important goals for health education efforts aimed at increasing rates of CRC screening. Participants' willingness to engage in detailed telephone conversations about CRC and CRC screening was encouraging.
