Anatomical Sites Of Involvement
Gout is an asymmetrical polyarticular disease, most often affecting the foot . There is a predilection for the first metatarsophalangeal joint, a condition known as podagra. Erosions are typically frequent along the medial and dorsal aspect of the joint , and hallux valgus deformity is often seen, though any joint can be affected. The hindfoot can also be involved. Calcaneal erosions are common, and there can be retrocalcaneal bursitis and Achilles tendon involvement 16. The hands and wrist are the next most common area of involvement with elbow and knee involvement being somewhat common . Less common sites of disease include the shoulder , hip, sacroiliac joints and the spine .

Diagnosing Gout: What To Expect At The Doctors Office
If youre unsure about whats causing your pain and other symptoms, youll likely visit various health care providers, which could include your internist/general practitioner, orthopedist, or podiatrist.
While your GP or internist may be able to diagnose and manage gout, if the diagnosis of gout is not clear, or if you arent getting better with initial treatment, you may be referred to a rheumatologist. A rheumatologist is a specialist who treats musculoskeletal disease and systemic autoimmune conditions, including gout.
There is no single, simple test to diagnose gout.
First, your doctor will perform a physical examination to assess your overall health and ask about your history of joint pain and other symptoms that suggest gout, as well as your family history and any pre-existing medical conditions you have or medications you take.
The doctor may check for pain in multiple joints. Over half of cases of acute gout occur in the big toe for the first time. Then over time, it can spread to other areas, like the middle of the foot, the ankle, knees, hands, the wrists, the elbows, and other joints as well, says Jonathan Greer, MD, a rheumatologist with Arthritis & Rheumatology Associates of Palm Beach in Florida.
Risk factors of gout that your doctor may consider:
- Family history of gout

Can Gout By Diagnosed By X Ray
X-Ray examinations are often not performed for acute gout attacks. This is because x-rays do not reveal any problems during early gout stages and cannot provide much information to give a confirmed diagnosis. X-Ray examinations are more likely performed for chronic gout patients to determine the progress of the disease and to identify other health problems linked to gout, such as: tophi, joint damage and deformity and possible other sites for gout flare ups.

The Four Stages Of Gout
Gout is best understood by seeing it as having four phases or stages :
Stage 1: High uric acid
Elevated uric acid without gout or kidney stone, this stage has no symptoms and is generally not treated.
Stage 2: Acute flares
This stage is marked by acute gout attacks causing pain and inflammation in one or more joints.
Stage 3: Intercritical periods
These are periods of time between acute attacks, during which a person feels normal but is at risk for recurrence of acute attacks.
Stage 4: Advanced gout
This is a stage of chronic gouty arthritis, in which there are lumps of uric acid, or tophi , frequent attacks of acute gout, and often a degree of pain even between attacks .

Signs And Symptoms Of Gout
Any joint can be affected by gout, but it usually affects joints towards the ends of the limbs, such as the toes, ankles, knees and fingers.
Signs and symptoms of gout include:
- severe pain in one or more joints
- the joint feeling hot and very tender
- swelling in and around the affected joint
- red, shiny skin over the affected joint
Symptoms develop rapidly over a few hours and typically last three to 10 days. After this time the pain should pass and the joint should return to normal.
Almost everyone with gout will experience further attacks at some point, usually within a year.

When Is Surgery Considered For Gout
The question of surgery for gout most commonly comes up when a patient has a large clump of urate crystals , which is causing problems. This may be if the tophus is on the bottom of the foot, and the person has difficulty walking on it, or on the side of the foot making it hard to wear shoes. An especially difficult problem is when the urate crystals inside the tophus break out to the skin surface. This then can allow bacteria a point of entry, which can lead to infection, which could even track back to the bone. Whenever possible, however, we try to avoid surgery to remove tophi. The problem is that the crystals are often extensive, and track back to the bone, so there is not a good healing surface once the tophus is removed. In some rare cases, such as when a tophus is infected or when its location is causing major disability, surgical removal may be considered.
Since it is hard to heal the skin after a tophus is removed, a skin graft may be needed. For this reason, we often try hard to manage the tophus medically. If we give high doses of medication to lower the urate level, such as allopurinol, over time the tophus will gradually reabsorb. In severe cases, we may consider using the intravenous medication pegloticase , since it lowers the urate level the most dramatically, and can lead to the fastest shrinkage of the tophus.

Heres What To Expect At The Doctors Office When You Suspect You Might Have Gout
If you have been experiencing warmth, redness, and excruciating and sudden pain in your big toe overnight or first thing in the morning, gout could be to blame. Gout, a form of arthritis that impacts 8.3 million American adults, causes a sudden onset of joint pain and inflammation that can impact your range of motion and ability to perform daily activities.
Some people in the middle of a gout flare report the pain being so severe that they cant bear to have a bedsheet touch their toes and find it hard to walk around.
Prevention Of Recurrent Attacks
Hyperuricemic therapy should be initiated in patients with frequent gout attacks, tophi or urate nephropathy. A low dosage of an NSAID or colchicine is effective in preventing acute gouty attacks. Hyperuricemic drug therapy should not be started until an acute attack of gouty arthritis has ended, because of the risk of increased mobilization of uric acid stores. A reasonable goal is to reduce the serum uric acid concentration to less than 6 mg per dL .
Uricosuric Drugs. These agents decrease the serum uric acid level by increasing renal excretion. Probenecid and sulfinpyrazone are used in patients who are considered underexcretors of uric acid. Uricosuric drugs should not be given to patients with a urine output of less than 1 mL per minute, a creatinine clearance of less than 50 mL per minute or a history of renal calculi. The physiologic decline in renal function that occurs with aging frequently limits the use of uricosuric agents.
Probenecid, in a dosage of 1 to 2 g per day, achieves satisfactory control in 60 to 85 percent of patients.23 It is important to note that the drug also blocks the tubular secretion of other organic acids. This may result in increased plasma concentrations of penicillins, cephalosporins, sulfonamides and indomethacin.

What Are Future Possible Treatments Of Gout
Fortunately, present medications are successful in the vast majority of gout patients. But some patients cannot tolerate our present arsenal of gout medications. For others, these agents are not sufficiently effective. Therefore, new treatments are continually being sought. Some of the more promising include anakinra, rilonacept, canakinumab, BCX4208 and arhalofenate.

The Role Of Medication In Prevention Of Gout
Table 3: Medications to pevent attacks of gout
Standard medications in preventing gout attacks
i. Colchicine : using the matches analogy discussed above1, using colchicine can be seen as dampening the uric acid matches. Colchicine does not lower the bodys store of uric acid, but it decreases the intensity of the bodys inflammatory reaction to these crystals. Recent studies have shown that at least one mechanism of colchicines action is by acting to prevent a cascade of reactions that lead to the production of interleukin 1-beta, which is an inflammatory protein , which is important in gouty inflammation.8
ii. Allopurinol: This agent is presently the most commonly used drug for the prevention of gout. Allopurinol blocks the enzyme xanthine oxidase, which blocks the breakdown of purines, thus decreasing the bodys total amount of uric acid. Allopurinol is effective in preventing gout no matter what the mechanism of the elevated uric acid was. Whether a person is making too much uric acid, or has difficulty excreting it via the kidney, allopurinols decrease in uric acid production leads to the same goal: a decreased total body uric acid.

- Calcium pyrophosphate deposition in pseudogout
Gout is the most common of the crystal arthropathies. Unlike rheumatoid, gout does not usually have a symmetric distribution. It most commonly affects the first metatarsophalangeal joint.
In patients with acute gout the X-ray may appear normal.
Juxta-articular erosions become visible in chronic gout.

Is It Gout Or Something Else
The pain and redness of gout can look like an infection or other conditions.
- Pseudogout is another form arthritis. The crystals formed in this condition are made of calcium pyrophospate, not uric acid. But like regular gout, the attack comes on all of a sudden. Joints become swollen, warm, painful, and stiff.
- Reactive arthritis is a reaction to infection that has similar signs.
- Psoriatic arthritis and infectious arthritis can look like gout, too.
What Can Increase Your Risk
A high level of uric acid in the blood is the main factor that increases your risk of developing gout. However, it’s still uncertain why some people with a high level of uric acid in the blood develop gout, while others with an equally high level don’t.
Other factors that may increase your risk of developing gout are outlined below.
