Inflammatory bowel disease (IBD) is a chronic, relapsing immune-mediated inflammation of the gastrointestinal tract. IBD includes two major disease entities: Crohn disease and ulcerative colitis. Imaging plays an important role in the diagnosis and surveillance of these complex disorders. Computed tomographic and magnetic resonance enterographic techniques have been refined in recent years to provide a superb means of evaluating the gastrointestinal tract for suspected IBD. Although the intestinal imaging manifestations of IBD have been extensively discussed in the radiology literature, extraintestinal imaging manifestations of IBD have received less attention...

BACKGROUND: Musculoskeletal US is a noninvasive imaging method for diagnosing and monitoring inflammatory rheumatic diseases. OBJECTIVES: To develop age- and gender-related arthrosonographic reference intervals for the hip joint of healthy children and adolescents. MATERIALS AND METHODS: In a cross-sectional US study, we examined both hip joints of 445 children and adolescents with an age range of 1 year to 18 years. We measured the distance between the bone surface and the outer margin of the joint capsule to define the bone-capsule distance, the joint capsule and cartilage thickness, and the capsule layer thickness...

Transient receptor potential (TRP) ion channels are important signaling components in nociceptive and inflammatory pathways. This is attributed to their ability to function as polymodal sensors of environmental stimuli (chemical and mechanical) and as effector molecules in receptor signaling pathways. TRP vanilloid 4 (TRPV4) is a nonselective cation channel that is activated by multiple endogenous stimuli including shear stress, membrane stretch, and arachidonic acid metabolites. TRPV4 contributes to many important physiological processes and dysregulation of its activity is associated with chronic conditions of metabolism, inflammation, peripheral neuropathies, musculoskeletal development, and cardiovascular regulation...

Telehealth refers to health care interactions that leverage telecommunication devices to provide medical care outside the traditional face-to-face, in-person medical encounter. Technology advances and research have expanded use of telehealth in health care delivery. Physical medicine and rehabilitation providers may use telehealth to deliver care to populations with neurologic and musculoskeletal conditions, commonly treated in both acute care and outpatient settings. Patients with impaired mobility and those living in locations with reduced access to care may particularly benefit...

Sarcoidosis is a multiorgan inflammatory disease that rarely involves the musculoskeletal system. A typical radiographic presentation is only noted with phalangeal lesions in the hands and feet, and other skeletal sites of sarcoidosis are a diagnostic imaging challenge [1]. We describe two cases of patients with sarcoidosis in whom pathologic bone marrow lesions were diagnosed on MRI scans. The magnetic resonance findings were non-specific and metastatic lesions or multiple myeloma were suspected. The case analysis serves to point to limitations of imaging studies in diagnosing bone sarcoidosis and underline the importance of cooperation between the radiologist and the clinician...

BACKGROUND: Simple bone cysts (SBC) have been documented to occur in adults with closed physeal plates, most commonly affecting the calcaneus in this patient subset. Although most authors theorize an association to trauma, etiology of simple bone cysts remains an enigma up to now. CASE PRESENTATION: A 26-year-old kickboxing coach sought consult for a painful right shoulder which on radiographs and magnetic resonance (MR) imaging showed a proximal humeral lesion with signs of ossification...

Tendon injury is a known complication of distal radius fracture plate and screw fixation. Targeted musculoskeletal sonography is uniquely capable of assessing both tendon integrity and hardware abnormalities not recognized on radiographs. Each of the 3 patients described presented with pain after an open reduction-internal fixation following a distal forearm fracture. In each patient, radiographic findings, specifically the hardware position, were interpreted as normal. Important radiographically occult observations were subsequently made with sonography, including 3 proud screws and tendon injuries, all of which required surgical treatment...

In the past 2 decades, sonoelastography has been progressively used as a tool to help evaluate soft-tissue elasticity and add to information obtained with conventional gray-scale and Doppler ultrasonographic techniques. Recently introduced on clinical scanners, shear-wave elastography (SWE) is considered to be more objective, quantitative, and reproducible than compression sonoelastography with increasing applications to the musculoskeletal system. SWE uses an acoustic radiation force pulse sequence to generate shear waves, which propagate perpendicular to the ultrasound beam, causing transient displacements...

We present a case of a 15-year-old male with history of back pain and bilateral lower limb radiculopathy due to fall. The magnetic resonance imaging scan showed disc bulge at L2-L3 level causing compression on contained nerve roots. In this case, computed tomography scan was indispensable for diagnosis and classification of the vertebral apophyseal fracture and to guide appropriate further management. Apophyseal ring fracture is an uncommon cause of back pain with radiculopathy in adolescents and athletes. High degree of suspicion is necessary to differentiate these injuries from disc herniation so as to further guide appropriate conservative or surgical management...

P Korsten, G Chehab
Musculoskeletal manifestations in the context of sarcoidosis are frequently observed. The rheumatologist regularly encounters this disease in clinical practice. In the present review, we aim to give a current overview of the manifestations and treatments relevant to the practicing rheumatologist. The most frequently encountered manifestation is Lofgren's syndrome, which is characterized by bilateral ankle periarthritis, bilateral hilar lymphadenopathy, and erythema nodosum and has an excellent prognosis. Chronic arthropathy most commonly manifests as oligoarthritis, which sometimes hampers its differentiation from spondylarthropathies, especially when sacroiliitis, enthesitis or dactylitis are simultaneously present...

Controversy exists as to whether different dynamic muscle actions produce divergent hypertrophic responses. The purpose of this paper was to conduct a systematic review and meta-analysis of randomized controlled trials comparing the hypertrophic effects of concentric versus eccentric training in healthy adults following regimented resistance training (RT). Studies were deemed eligible for inclusion if they met the following criteria: 1) were an experimental trial published in an English-language refereed journal; 2) directly compared concentric and eccentric actions without the use of external implements (i...

The use of high-frequency (high-resolution) musculoskeletal ultrasonography is increasing and has shown promising utility in many areas of medicine. The utility of musculoskeletal ultrasonography for foot and ankle complaints has not been widely investigated, however. Although some conditions of the foot and ankle are easily diagnosed by physical examination, others can have nonspecific examination findings, making optimal treatment decisions difficult. We hypothesized that high-resolution musculoskeletal ultrasound scanning of the foot and ankle can affect the diagnosis and/or treatment for patients presenting with foot or ankle complaints...

Lipomatous lesions are common musculoskeletal lesions that can arise within the soft tissues, bone, neurovascular structures, and synovium. The majority of these lesions are benign, and many of the benign lesions can be diagnosed by radiologic evaluation. However, radiologic differences between benign and malignant lipomatous lesions may be subtle and pathologic correlation is often needed. The use of sonography, computed tomography (CT), and magnetic resonance imaging (MRI) is useful not only in portraying fat within the lesion, but also for evaluating the presence and extent of soft tissue components...

Evaluation for suspected inflammatory arthritis as a cause for chronic extremity joint pain often relies on imaging. This review first discusses the characteristic osseous and soft tissue abnormalities seen with inflammatory arthritis and how they may be imaged. It is essential that imaging results are interpreted in the context of clinical and serologic results to add specificity as there is significant overlap of imaging findings among the various types of arthritis. This review provides recommendations for imaging evaluation of specific types of inflammatory arthritis, including rheumatoid arthritis, seronegative spondyloarthropathy, gout, calcium pyrophosphate dihydrate disease (or pseudogout), and erosive osteoarthritis...
