CACPR Featured in UMB Spotlight

The Winter 2019 issue of UMB Spotlight includes a cover story about CACPR and the challenge of confronting chronic pain. The article features quotes from several members of the CACPR Executive Committee, and emphasizes the necessity of collaboration as we aim to understand the complex nature of chronic pain.
Joel D. Greenspan Addresses the Topic of Pain at the Maryland Science Center

On January 11, 2019, Dr. Greenspan gave a “Lunch & Learn” presentation at the Maryland Science Center. The “Lunch & Learn” seminar series is a new monthly initiative of the Maryland Science Center, which began in October 2018. Dr. Greenspan’s presentation, “What Everyone Should Know about Pain”, was live streamed with approximately 400 viewers.

Watch the Facebook video of Dr. Greenspan's presentation here. (P lease excuse the first few minutes of technical difficulties.)

David Seminowicz, PhD, is an Associate Professor in the Department of Neural and Pain Sciences, School of Dentistry.  His research lab is interested in discovering the brain mechanisms of pain. Pain is a complex experience, and work currently underway is slowly beginning to reveal the relationship between brain activity and various aspects of the pain experience.
One major focus is on the effect of attention states on acute pain and in people with various chronic pain conditions. In the case of chronic pain, Dr. Seminowicz’s research team is investigating the effects of different treatments on abnormal brain activity and anatomy, using task and resting state functional MRI, and structural MRI including diffusion tensor imaging (DTI). [Note references # 2, 5, 6, and 8]

While neuroimaging experiments in humans can tell us about the experience of pain, using imaging in animal models of chronic pain allows Dr. Seminowicz to ask questions about the involvement of precise brain areas in pain-related behavior. [Note references #1 and 3.]. His previous research demonstrated that the development of anxiety-like behaviors in the rat coincided with the volumetric decreases in prefrontal cortical (PFC) areas in a model of chronic neuropathic pain. Rodent models also provide the ability to perform histological and biochemical experiments on the same animals that have had MRIs. Dr. Seminowicz’s research team is currently investigating the roles of the PFC in other pain behaviors and using functional MRI to investigate the connectivity between PFC and other brain areas.

In 1996, UMB recognized the importance of chronic pain as a significant health problem and established the Organized Research Center (ORC) for Persistent Pain in the School of Dentistry (SOD).

In its June 2011 report, “Relieving Pain in America,” the Institute of Medicine documented that at least 100 million U.S. adults suffer from common chronic pain conditions, with national annual costs and lost productivity estimated to be in the range of $560 billion to $635 billion. In recognition of this greater need, UMB President Jay A. Perman, MD, established the Center to Advance Chronic Pain Research as a Universitywide organized research center.
