Sonography complements physical exam in identifying juvenile inflammatory arthritis in children

05.05.2011
Juvenile Inflammatory Arthritis (JIA) is a potentially debilitating childhood disease.

Early detection and treatment of active arthritis may avert long term joint damage and disability. Research has shown that sonography with power Doppler can facilitate making assessments in joint activity and sub-clinical disease, according to research being presented at the 2011 American Roentgen Ray Society's annual meeting.

The study, performed at Albert Einstein College of Medicine's Montefiore Medical Center, in Bronx, NY, compares sonography with power Doppler to physical examination in evaluating disease activity in the knees and ankles of children with JIA.

Eighty-four joints in 19 patients were evaluated; of these, 65 joints were concordant on both sonography and physical examination. Of the remaining 19 joints, 14 were active on sonography and inactive on physical examination. Five of the 14 joints were found to have subclinical disease at the time of the initial physical examination, while 8 of the 14 joints demonstrated mild hyperemia as the only indicator of disease activity on sonography, which was a false positive. Of the 5 joints active on physical examination and inactive on sonography, 4 had subtalar disease.

"In patients with at least one active joint on physical examination, ultrasound augments the physical exam by identifying subclinical disease (in other joints). Our study confirmed that patients with evidence of subclinical disease do, in many cases, go on to have clinically evident disease," said Vikash Panghaal, MD, lead author of the study.

"Certain combinations of physical exam findings are highly sensitive, and in these instances, ultrasound does not contribute to clinical management. Subtalar disease is poorly assessed using ultrasound," he said.

"Unlike previous studies, our study included a 2-5 month follow-up physical exam after the initial physical exam and ultrasound, which allowed confirmation of subclinical disease," said Dr. Panghaal. "We also determined the sensitivity and specificity of various aspects of the physical exam for identifying synovitis and correlated this with ultrasound findings," said Dr. Panghaal.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
