MRI of the skeleton in prostate cancer staging.

Objective: To explore the value of MRI in the detection of bone metastases in newly diagnosed prostate cancer.

Material And Methods: MRI examinations of the axial skeleton in 76 patients with newly diagnosed prostate cancer were reviewed, and the relation of these findings to the serum level of prostate specific antigen (PSA) was examined.

Results: MRI indicated bone metastases in 26/76 patients (34%) in the entire study group, in 4/24 (17%) with serum PSA <20 ng/ml and in 22/52 (42%) with serum PSA >20 ng/ml.

Inflammatory joint manifestations are prevalent in psoriasis: prevalence study of joint and axial involvement in psoriatic patients, and evaluation of a psoriatic and arthritic questionnaire.

To examine the prevalence of inflammatory manifestations, such as peripheral arthritis, axial disease, undifferentiated spondyloarthropathy (uSpA) and enthesopathies in patients with psoriasis, and to evaluate a psoriatic and arthritic questionnaire (PAQ) to identify patients with arthritis. Methods. An evaluation of a questionnaire (PAQ) in a hospital- and community-based population of 276 psoriatic patients, and clinical, radiological, and laboratory examination of the 202 patients answering the questionnaire and willing to participate in the subsequent study.
