Prevalence of ultrasound and clinical findings suggestive of inflammatory arthritis in children with skin psoriasis
Authors' conclusion
US abnormalities were higher in the Sy group, with synovitis and enthesitis as the most prevalent findings.
Study context

- Exposure
- Symptomatic vs asymptomatic children with PsO

- Symptomatic (Sy)n = 15
- Outcome
- Prevalence of clinical and US (grey-scale and Doppler) abnormalities in joints, periarticular structures and nails
Methodological detailsconsecutive children, independent examiners blinded to each other's assessment
