Radiologists Identify Teenage Self-Injury

"This is a new way for radiologists to impact public and mental health,” said the study's senior author, William E. Shiels II, D.O., chairman of the department of radiology at Nationwide Children's Hospital (Columbus, OH, USA), and president of The Children's Radiological Institute (Columbus, OH, USA). "Radiologists can be in a position to interrupt a cycle of self-harm with effective, early diagnosis and referral for appropriate behavioral health and foreign body removal."

Self-injury, or self-harm, refers to a range of behaviors in which an individual deliberately inflicts harm to his or her body without suicidal intent. It is a disturbing trend among adolescents, particularly girls. Prevalence is unknown because many cases go unreported, but recent studies have reported that one in five high school students has practiced intentional self-injury at least once. More typical forms of self-injury include cutting of the skin, burning, bruising, hair pulling, breaking bones, or swallowing toxic substances. In instances of self-embedding, objects are used to puncture the skin or are embedded into the wound after cutting.

Dr. Shiels and colleagues evaluated 21 episodes of self-embedding behavior in 11 teenagers, including nine girls and two boys, age 14 to 18. Objects had been present for time periods between two days and an unknown number of years. Using ultrasound and/or fluoroscopic guidance, interventional pediatric radiologists removed 68 of the 76 embedded foreign objects found in the patients. The embedded objects included metal, glass, wood, plastic, graphite, stone, and crayon. The objects were embedded during injuries to the arms, ankles, feet, hands, and neck. One 18-year-old patient with repetitive behavior had self-embedded 35 objects over two years, including staples, a comb tooth, a fork tine, a cotter pin, and nail polish wands.

Ultrasound guidance allowed the researchers to detect the presence and location of wood, crayons, and plastic objects, not detectable on X-ray examinations. Removal was performed through small incisions in the skin that left little or no scarring and was successful in all cases. There was one incident of fragmentation, but all fragments were removed.

"Early detection and removal of these foreign bodies are key steps for these teenagers to engage in effective therapy and interrupt their cycle of self-harm, so they can recover and grow as healthy and successful adults with good coping skills,” Dr. Shiels said.
