Hypothesis
Can ultrasonography and color Doppler imaging effectively detect enthesitis in juvenile idiopathic arthritis patients compared to healthy controls?
Conclusion
Ultrasonography revealed that gluteus medius insertions in JIA patients were thicker and showed signs of enthesitis compared to healthy controls.
Supporting Evidence
- US detected decreased echogenicity of the entheses in 53% of the iliac crests.
- US revealed significantly thicker entheses in JIA patients compared to healthy controls.
- Hyperemia was detected by CD in 37% of the iliac crests.
Takeaway
Doctors used special imaging to see if kids with arthritis had inflammation where muscles attach to bones, and they found it was more common in the kids with arthritis.
Methodology
The study involved clinical assessments and imaging (ultrasonography and color Doppler) of 38 JIA patients and 38 healthy controls.
Potential Biases
The examiner was not blinded to whether they were assessing JIA patients or healthy controls, which could introduce bias.
Limitations
The study was descriptive and not designed to compare clinical and imaging results directly.
Participant Demographics
38 patients aged 7-18 years, with a median age of 13 years; included 15 boys and 23 girls.
