In Other Words: Insult—A “Sick Burn” or a Burn That Makes You Sick?

2 comments

You probably think of a rude or offensive remark when you think of the word insult, but to biomedical researchers, an insult is the cause of some kind of injury to the body. Insults can come in a variety of forms, such as an infection or a physical trauma.

On the right are spherical bacteria on a rough surface. Under the images, text reads: “Did you know? In biomedical science, an insult is the cause of some kind of injury to the body.”

Scientist Studies Burn Therapies After Being Severely Burned as a Child

“If I was going to do science, I wanted it to help people,” says Julia Bohannon, Ph.D., an assistant professor of anesthesiology at Vanderbilt University Medical Center in Nashville, Tennessee.

Dr. Bohannon researches therapies that could help prevent infections in patients with severe burn injuries. Infections are common in these patients because burn injuries typically suppress the immune system. Dr. Bohannon originally planned to become a burn surgeon, inspired by the doctor who treated her after she was severely burned as a child. But during her junior year of college at Eastern Kentucky University in Richmond, she started working in a genetics lab and enjoyed it so much that she began considering a research career.

Choosing a Path Forward

After graduating with her bachelor’s degree, Dr. Bohannon worked for 2 gap years in a translational research lab at the University of Kentucky to decide between pursuing an M.D. or a Ph.D. She ultimately entered a Ph.D. program at the University of Texas Medical Branch in Galveston and conducted research in the lab of Tracy Toliver-Kinsky, Ph.D., at the Shriners Children’s burn center. Upon earning her Ph.D., Dr. Bohannon took a postdoctoral position with Edward Sherwood, Ph.D., at the University of Texas Medical Branch, where she studied potential treatments to improve immune cell function after burns. To continue her work, she followed Dr. Sherwood a year later when he moved to Vanderbilt University Medical Center.

A World Without Pain

In an immersive virtual reality environment called “Snow World,” burn patients distract themselves from their pain by tossing snow balls, building snowmen and interacting with penguins. Credit: Ari Hollander and Howard Rose, copyright Hunter Hoffman, UW, www.vrpain.com Exit icon.

You glide across an icy canyon where you meet smiling snowmen, waddling penguins and a glistening river that winds forever. You toss snowballs, hear them smash against igloos, then watch them explode in vibrant colors.

Back in the real world, a dentist digs around your mouth to remove an impacted tooth, a procedure that really, really hurts. Could experiencing a “virtual” world distract you from the pain? NIGMS grantees David Patterson Exit icon and Hunter Hoffman Exit icon show it can.

Patterson, a psychologist at the University of Washington (UW) in Seattle, and Hoffman, a UW cognitive psychologist, helped create the virtual reality program “Snow World” in an effort to reduce excessive pain experienced by burn patients. However, the researchers expect Snow World to help alleviate all kinds of pain, including pain experienced during dental procedures. Continue reading “A World Without Pain”

The pain stemming from second- and third-degree burns is among the worst known. Throughout recovery, the intense, disabling pain patients feel can lead to sleeplessness, anxiety and depression.

David Patterson first entered a burn ward as a psychologist hoping to help patients cope with these issues. He saw patients refuse wound cleaning because of how painful it could be.

“I’ve learned how horribly difficult it is to control burn and trauma pain with medications alone,” he says. “The amount of pain people feel affects how well they adjust in the long term.” Pain and the mental, social and emotional problems it causes also hinder the body’s ability to heal physically.

Today, Patterson is committed to helping burn patients overcome pain, allowing their bodies—as well as their minds—to heal more efficiently. Using virtual reality (VR) technology, Patterson has found an effective complement to pain-relieving drugs such as morphine and other opioid analgesics.

Patterson’s Findings

“To be honest, for acute pain, you give someone a shot or a pill and it’s instant relief,” Patterson says. But opioid analgesics carry problems.  Sometimes patients don’t respond well to morphine or require high dosages that carry strong side effects.

When burn patients undergo routine wound care, the pain can be excruciating—as bad as or worse than the original burn incident. Realizing the brain can take only so many stimuli, Patterson collaborated with fellow UW psychologist Hunter Hoffman to experiment with VR in pain relief. When combined with minimal pain medications, VR is a powerful solution to acute pain. By providing a computer-generated reality—for example, an icy canyon filled with snowmen and Paul Simon’s music, as in the case of their creation SnowWorld—the patient’s eyes, ears and mind are so occupied that he or she can effectively ignore the pain.

Patterson and his team found that VR pain reduction strategies are as powerful as opioid analgesics, without the negative side effects. The technology doesn’t require specialized expertise and is getting progressively less expensive, making it economically attractive.  At least eight hospitals have adopted the methods as part of their clinical program, allowing Patterson an opportunity to conduct further studies on the long-term effects of using these complementary methods and the efficacy of the techniques on other kinds of pain.
