More doctors use ultrasound to diagnose, manage rheumatic diseases

29.10.2012
ACR supports best practices for ultrasonography use in rheumatology

More rheumatologists are embracing musculoskeletal ultrasound (MSUS) to diagnose and manage rheumatic diseases. In response, the American College of Rheumatology (ACR) assembled a task force to investigate and determine best practices for use of MSUS in rheumatology practice.

The resulting scenario-based recommendations, which aim to help clinicians understand when it is reasonable to integrate MSUS into their rheumatology practices, now appear online in Arthritis Care & Research.

In Europe, more than 100 million individuals are affected by rheumatic diseases, according to the European League Against Rheumatism (EULAR). The ACR estimates that nearly 50 million Americans are burdened by arthritis and more than 7 million individuals suffer from inflammatory rheumatic diseases such as systemic lupus erythematosus, rheumatoid arthritis and gout.

"With so many people affected by rheumatic diseases, including arthritis, a diagnostic tool such as MSUS that is minimally invasive and with little risk to patients is an important tool for rheumatologists," explains lead researcher Dr. Tim McAlindon from Tufts Medical Center in Boston, Mass. "Our task force goal was to establish when use of MSUS was 'reasonable' in a number of medical situations."

The task force reviewed medical literature to come up with scenario-based recommendations for how MSUS could be used in rheumatology practice. These recommendations include a rating by type of evidence, with Level A supported by at least two randomized clinical trials or one or more meta-analyses of randomized trials; Level B backed by one randomized trial, non-randomized studies or meta-analyses of non-randomized studies; and Level C confirmed by consensus expert opinion, case studies, or standard clinical care.

The complete list of 14 recommendations of the reasonable use of MSUS in rheumatology, along with level of evidence, is published in the article. Partial list of recommendations includes:

For a patient with articular pain, swelling or mechanical symptoms, without definitive diagnosis on clinical exam, it is reasonable to use MSUS to further elucidate the diagnosis at the following joints: glenohumeral, acromioclavicular, sternoclavicular, elbow, wrist, metacarpophalangeal, interphalangeal, hip, knee, ankle, midfoot and metatarsophalangeal. Level of evidence: B.

For a patient with diagnosed inflammatory arthritis and new or ongoing symptoms without definitive diagnosis on clinical exam, it is reasonable to use MSUS to evaluate for inflammatory disease activity, structural damage or emergence of an alternate cause at the following sites: glenohumeral, acromioclavicular, elbow, wrist, metacarpophalangeal, interphalangeal, hip, knee, ankle, midfoot and metatarsophalangeal, and entheseal. Level B.

For a patient with shoulder pain or mechanical symptoms, without definitive diagnosis on clinical exam, it is reasonable to use MSUS to evaluate underlying structural disorders; but not for adhesive capsulitis or as preparation for surgical intervention. Level B.

It is reasonable to use MSUS to evaluate the parotid and submandibular glands in a patient being evaluated for Sjögren's disease to determine whether they have typical changes as further evidence of the disorder. Level B.

For a patient with symptoms in the region of a joint whose evaluation is obfuscated by adipose or other local derangements of soft tissue, it is reasonable to use MSUS to facilitate clinical assessment at the glenohumeral, acromioclavicular, elbow, wrist, hand, metacarpophalangeal, interphalangeal, hip, knee, ankle/foot, and metatarsophalangeal joints. Level C.

For a patient with regional neuropathic pain without definitive diagnosis on clinical exam, it is reasonable to use MSUS to diagnose entrapment of the median nerve at the carpal tunnel; ulnar nerve at the cubital tunnel; and posterior tibial nerve at the tarsal tunnel. Level B.

It is reasonable to use MSUS to guide articular and peri-articular aspiration or injection at sites that include the synovial, tenosynovial, bursal, peritendinous and perientheseal areas. Level A.

The benefits of MSUS use include a faster, more accurate diagnosis, better measurement of treatment success, reduced procedural pain, and improved patient satisfaction. However, the authors highlight that economic impact was not part of this study. Dr. McAlindon concludes, "Further study of the cost-effectiveness and long-term outcomes of MSUS is necessary to determine its value compared to other interventions."

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
