Abstract: Myxomas are predominantly located in the right on left atrium. We report an unusual case of a myxoma adherent to the aortic valve. The child presented with symptoms of subaortic stenosis. By invasive methods a tumor was diagnosed located at the aortic valve. After surgical removal the child recovered soon and is doing well. According to our knowledge this is the first report of a myxoma of the aortic valve.

Abstract: Twenty-five patients with fracture of the penis were treated surgically between 1968 and 1984. Long-term follow-up was obtained in 17. In no case were there any early post-operative complications. All patients stated that they were achieving normal, painless erections; two patients developed a slight penile curvature but this did not affect their sexual activities. We strongly recommend early surgical intervention because of these encouraging results. Urethral injury associated with the fracture did not occur in this series.

Abstract: Three models for continuing professional education (CPE) are described: an education model, which reflects the mainstream of CPE practice and focuses on educational objectives, teaching methods, organization of educational experiences, and assessment; a social change model, which considers the total environment in which CPE occurs; and a problem-based model, which focuses on the professional context and order of complexity of professional problems. Each model is described, and its strengths and drawbacks as applied to continuing medical education are discussed.
