The Wrisberg variant of the discoid lateral meniscus is a rare condition with a highly suggestive clinical history. The musculoskeletal radiologist should consider this diagnosis whenever a discoid lateral meniscus is identified because making this elusive diagnosis may prove immensely useful for the orthopedic surgeon.

In 1994 ten NIH institutes sponsored an interagency workshop focusing on biobehavioral pain research. The workshop had three major goals: (1) to review the current status of biobehavioral pain research (2) to identify critical research needs, and (3) to enhance interdisciplinary and interagency cooperation in pain research. The purpose of this article is to summarize the presentations at this meeting and to highlight some of the key research recommendations. Research topics addressed include (a) understanding critical interfaces between biology and behavior; (b) pain, suffering, and emotion; (c) pain and behavior; (d) behavior-related interventions; (e) commonalities and differences in pain expression, experience, and treatment; and (f) pain in special populations. The article concludes with a summary of NIH pain research activities that have taken place since the workshop.
