• Pain

  Gout is an inflammatory-rheumatic disease characterized by an elevated serum urate concentration and recurrent flares, including painful, hot, red, and swollen joints and surrounding tissue. [healio.com]

  The patient's back pain and paraparesis of the lower left limb improved. The clinician should include spinal gout in the differential diagnosis when dealing with patients with gout and axial pain with or without neurologic deficits. [ncbi.nlm.nih.gov]

  One suspects, from what elbow gout sufferers say, that it isn't as painful or debilitating as gout in its primary areas. Most people who get elbow gout are experienced sufferers, and they don't say the pain is agonising. [best-gout-remedies.com]

  Resection of joints, arthroplasty, and arthrodesis of painful joints may lessen pain and improve function to a limited degree. Curettage or partial resection of tendons may help preserve function. [journals.lww.com]

  The plant-based treatment known as colchicine (Mitigare) can also help reduce pain caused by gout. Gout should be treated as early as possible to prevent painful symptoms and complications caused by tophi. [healthline.com]

• Swelling

  Computed tomography scan of the swelling showed extra-articular soft-tissue swelling, with no bony erosion ([Figure 1]b and [Figure 1]c). [err.eg.net]

  Radiograph of the lesion showed a soft-tissue swelling without involvement of underlying bone with no evidence of calcification. FNA from the swelling, yielded whitish, and granular material. [cytojournal.com]

  Direct fine needle aspiration cytology was done from the left elbow swelling, which yielded blood mixed brownish material, and from the right index finger swelling, which yielded whitish chalky material. [cureus.com]

  Conclusions We conclude that the extranuclear DNA has been ejected by the neutrophils in order to trap the inflammation inducing crystals. [ard.bmj.com]

• Severe Pain

  Abstract Background A 67-year-old man presented to a rheumatology clinic with a 1-week history of severe pain and swelling of his right knee. [nature.com]

  Gout can cause episodes of severe pain called gout attacks. Without treatment, gout can become a chronic condition and increase your risk of developing tophi and joint damage. With gout, tophi may not develop right away. [healthline.com]

• Weight Loss

  loss and reduction in alcohol intake where appropriate. [pcds.org.uk]

  Weakness, fatigue, weight loss, anorexia, vomiting, flank or abdominal pain, constipation and diarrhea are additional symptoms seen in some patients due to hypocortisolemia. [orpha.net]

  Weight loss should be gradual and combined with daily exercise. Extreme weight loss or starvation diets increase cell breakdown in your body, which can raise urate levels. [versusarthritis.org]

• Abdominal Pain

  Weakness, fatigue, weight loss, anorexia, vomiting, flank or abdominal pain, constipation and diarrhea are additional symptoms seen in some patients due to hypocortisolemia. [orpha.net]

  These drugs can also cause tummy upset (most commonly diarrhoea and cramping abdominal pain) shortly after injections. About 20% of patients develop gallstones after long-term use but this does not usually cause symptoms. [yourhormones.info]

  Side effects of SRL include abdominal pain, nausea, flatulence, diarrhea, and hyperglycemia. [ncbi.nlm.nih.gov]

• Joint Deformity

  Complications include bone destruction, joint deformities, and, as in the present case, secondary infections. Diagnosis can be made on clinical grounds and confirmed with the visualization of uric acid crystals under light microscopy. [jaoa.org]

  Overview Chronic symptoms such as joint deformity and limitation of motion in affected joints may occur if several attacks of gout occur each year. Uric acid deposits called tophi develop in cartilage tissue, tendons, and soft tissues. [medlineplus.gov]

  The formation of these mineralized masses can also lead to chronic arthritis and joint deformity. Causes Tophi generally start to develop in the joints and tissues in the advanced chronic tophaceous stage. [verywellhealth.com]

  Physical examination revealed swelling, local erythema (Figure 1a) and pain on palpation of the right big toe. Serum C-reactive protein level was 14.6 mg/L (normal range: <10), and uric acid level was 10.1 mg/dl (normal range: 3.5-7.2). [archivesofrheumatology.org]

  Symptoms such as pain, erythema, and swelling are related to the precipitation of uric acid crystals in joint spaces and soft tissues [ 2 ]. [bmcresnotes.biomedcentral.com]

  Cutaneous erythema associated with the attack may extend beyond the involved joint and resemble cellulitis. Desquamation of the skin may occur as the attack resolves. [rheumatology-center.eu]

  If they are inflamed, there is erythema of the overlying skin. Whitish chalky material may be seen in ulcerated tophi. Tophi may appear at any site, but the most common sites are the digits of the hands and feet and the olecranon bursa. [ajmc.com]

• Renal Function Impairment

  In patients with renal impairment, the dose of allopurinol must be adjusted according to renal function [ 44 ], and some uricosuric drugs may not be effective—such as probenecid and sulphinpyrazone—in patients with moderate renal function impairment, [rheumatology.oxfordjournals.org]

• Uric Acid Increased

  Tophi are the accumulation of the MSU crystals which themselves (sometimes, not always) form when the concentration of uric acid in serum (blood) increases. [best-gout-remedies.com]

  The mechanisms by which diuretics contribute to elevated serum uric acid levels are: decreased filtration of uric acid, increased reabsorption, as well as decreased secretion [12]. [ncbi.nlm.nih.gov]

Treatments with antibiotics and nonsteroidal antiinflammatory drugs were ineffective. However, prednisolone therapy was highly effective, and the patient's symptoms were rapidly ameliorated. [ncbi.nlm.nih.gov]

Given its rarity, there is no elective treatment. As in our case, given the failure of medical treatment, one may opt for surgery. [hindawi.com]
