Crystal arthropathies are a group of joint disorders due to deposition of crystals in and around joints which lead to joint destruction and soft tissue masses. [radiopaedia.org]

Calcium pyrophosphate deposition disease should be on the differential diagnosis in the elderly patient presenting with a clinical picture that resembles “seronegative” RA, with morning stiffness, synovial thickening, localized edema, and restricted motion [mdedge.com]

The disease course was characterised by acute episodic arthritis in 16 (32%) patients and by persistent symptoms (with or without synovitis) in 34 (68%). [ncbi.nlm.nih.gov]

Autoimmune arthritis happens when your body's immune system attacks healthy cells in your body by mistake. Rheumatoid arthritis is the most common form of this kind of arthritis. Juvenile arthritis is a type of arthritis that happens in children. [icdlist.com]

This leads to attacks of joint swelling and pain in the knees, wrists, ankles, and other joints. Among older adults, CPPD is a common cause of sudden (acute) arthritis in one joint. [medlineplus.gov]

Generic features of joint swelling, localised warmth, pyrexia and painful reduced range of movement were evident in the presentation descriptions of all of the cases we reviewed emphasizing the close resemblance of peri-prosthetic arthropathy with infection [ghrnet.org]

In general, gout includes joint swelling in both the lower and upper extremities. [clevelandclinicmeded.com]

The majority of patients with rheumatoid arthritis will test positive for rheumatoid factors and a rheumatoid arthritis diagnosis requires the presence of certain other symptoms: morning stiffness, multiple joint swelling, rheumatoid nodules, and evidence [physio-pedia.com]

For instance, a 50-year-old woman with symmetric, progressive polyarticular joint swelling and prolonged morning stiffness would seem to have rheumatoid arthritis. [aafp.org]

Peri-prosthetic infection can present acutely with features including erythema, localized warmth around the joint, effusion, pyrexia and general lethargy. [omicsonline.org]

In the absence of joint effusion or indications to obtain a synovial biopsy, chondrocalcinosis is presumptive of CPPD deposition. One exception is chondrocalcinosis due to CaOx in some patients with chronic renal failure. [what-when-how.com]

Spontaneous ruptures of the tibialis anterior, quadriceps, and Achilles tendons have been reported. 5,6 In the acute stage of gout, MRI findings of the joint effusion and synovial thickening are nonspecific. [appliedradiology.com]

Treatment  The acute attack  Resting the joint  Applying ice packs if pain is severe,  NSAIDs  Colchicine (may cause diarrhoea, nausea and vomiting)  A tense joint effusion may require aspiration and intra-articular injection of corticosteroids. [slideshare.net]

Musculoskeletal ultrasound of the knee showing joint effusion and hyperechoic signals consistent with CPP-crystal synovial calcifications (longitudinal view of a knee in extension). [rheumatologyadvisor.com]

For example, the acute stage of Lyme disease may include polyarticular arthralgias, whereas the chronic phase may include oligoarthritis, primarily in the knees. 17 SYMMETRY Joint involvement tends to be symmetric in systemic diseases such as rheumatoid [aafp.org]

The most frequently reported adverse effects are diarrhea, back pain, headaches, and arthralgias. Also, patients should be monitored for thromboembolic events and increased hepatic transaminases. [clevelandclinicmeded.com]

If the patient later suffers from chronic arthralgias, corticosteroids should be avoided [24]. Steroids are administered when inflammatory symptoms are resistant to NSAIDs [75]. [physio-pedia.com]

Radiographs may reveal chondrocalcinosis or soft-tissue calcifications. [what-when-how.com]
