- Background: The purpose is to evaluate the accuracy of computed tomography (CT) in the pulmonary staging of osteosarcoma. Patients and methods: Fifty-one patients presenting with osteosarcoma and at initial CT considered metastatic to the chest had lung surgery. Two teams of two senior radiologists independently reviewed all CT examinations. Their results were compared to the histological studies. Results: One hundred nineteen CT's were reviewed. The 2 teams found 247 and 268 nodules on the initial, and 143 and 146 nodules on the preoperative CT. Histological studies confirmed metastatic nodules in 29 patients. Two hundred four nodules were excised and studied. One hundred nine were metastases. The 22 patients without metastases had 53 negative nodules removed. In the 29 patients with metastases, 151 nodules were removed, and 42 were non-metastatic. The positive predictive value was 53% with regard to 'nodules', and 57% with regard to 'patients'. Only 4 out of 13 patients with one nodule at surgery were metastatic, but all patients with more than 7 nodules were metastatic. The 46 cases with several available CT's, showed that no change in the number of nodules was more frequent in benign lesions. Other criteria revealed no significant difference. Conclusion: CT positive predictive value is limited, but as surgery is the only way to cure metastatic patients, CT will still be used as the reference technique until a more specific approach can be found.

- This article summarizes the proceedings of a symposium at the 2002 RSA meeting in San Francisco, California. The chair was Peter Monti and co-chair was Nancy Barnett. The aim of the symposium was to bring together researchers from the United States, Sweden, and Mexico to present current findings on the development and implementation of screening and intervention research in Emergency Departments (ED). Cheryl Cherpitel presented findings on the performance of the Rapid Alcohol Problems Screen (RAPS4), a 4-item instrument used for screening for alcohol dependence and harmful drinking in the ED. Dr. Cherpitel also presented for her collaborator, Guilherme Borges, their research on the performance of a number of screening measures including the RAPS among Mexicans and Mexican-Americans with alcohol-related disorders in the ED. Preben Bendtsen described the implementation of an alcohol screening and intervention procedure delivered by ordinary ED staff in Sweden. Nancy Barnett presented data on characteristics related to readiness to change alcohol use in a sample of young adults who were treated in an ED for injury or intoxication.
