• Soft Tissue Mass

  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]

• Localized Edema

  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]

• Arthritis

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

  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]

• Joint Swelling

  Permanent joint damage can occur without treatment. Call your health care provider if you have attacks of joint swelling and joint pain. There is no known way to prevent this disorder. [medlineplus.gov]

  Patients have joint pain, synovitis with joint tenderness, and swelling. [clevelandclinicmeded.com]

  In an acute joint bleed, patients may report sensations of tingling and warmth, followed by pain, swelling and decreased motion. [physio-pedia.com]

  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]

  MIGRATORY ARTHRITIS Migratory arthritis is characterized by rapid onset of swelling in one or two joints, with resolution over a few days. [aafp.org]

• Joint Effusion

  Examination features including joint effusion, joint line tenderness and reduced range of motion are common to both inflammatory and septic sources of arthropathy. [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]

• Arthralgia

  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]

Differentiation of crystal arthropathy from septic arthritis is the primary aim of the diagnostic workup process. Cases of simultaneous crystal arthropathy and septic arthritis can also occur however, further complicating the clinical evaluation[6]. [ghrnet.org]

Classic radiographic findings are highly suggestive (see Workup ). [emedicine.medscape.com]

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

• Hypocalciuria

  The phosphocalcium balance was altered in nine (18%) cases: six patients had hypercalciuria two hyperphosphaturia, two hypocalciuria, one hypophosphaturia and one hypercalcemia. [ncbi.nlm.nih.gov]

In trials of gout, studies focus on acute symptomatic treatment, foregoing chronic management, which is aimed at reducing the concentration of serum urate. [ncbi.nlm.nih.gov]

What to Expect The diagnosis and treatment of gout and crystal arthropathy requires a careful review of a patient’s symptoms, physical findings, and previous testing. [massgeneral.org]

Prognosis [ 2 ] Acute attacks usually resolve within ten days. [ 9 ] Some patients develop progressive joint damage with functional limitation. Prognosis will also be dependent on any underlying cause. [patient.info]

The prognosis for individual attacks of acute calcium pyrophosphate arthritis is usually excellent. However, chronic arthritis can occur, and severe destructive arthropathy resembling neurogenic arthropathy (Charcot joints) occasionally occurs. [merckmanuals.com]

 Prognosis  1. Acute attacks self-limited, resolve 7-10 days  2. Progressive joint damage; destructive arthropathy resembling neuropathic(Charcot’s) joints  3. Large joint arthropathy may require joint replacement 54. II. [slideshare.net]

As the symptoms and signs of both infectious and acute CPP crystal disease overlap and their treatment and prognosis differ greatly, a correct differential diagnosis is mandatory in clinical practice [ 3 ]. [synapse.koreamed.org]

Prognosis CPPD crystal deposition disease is a chronic (long-lasting) disorder with recurrent flare-ups. This means it may occur periodically throughout your lifetime. Some people have only one or at the most a few attacks in a lifetime. [orthop.washington.edu]
