Overview

Arthritis (from Greek arthro-, joint + -itis, inflammation; plural: arthritides) could be defined as painful joint damage. It might be as part of a systemic disorder or a single joint involvement. Arthritis may present as joint pain (arthralgia), swelling, erythema, warmness, and limitation of movement. It could be classified according to the number of involved joints, presence of inflammation, or duration of symptoms. Osteoarthritis (also known as degenerative joint disease) is the most common form of arthritis in the United States which involves up to 10% of population older than 60 years. Inflammatory arthritis is common in systemic autoimmune disorders, such as rheumatoid arthritis and systemic lupus erythematosus (SLE) and is part of diagnostic criteria for this spectrum of diseases. Disease course in systemic disorders is usually chronic and multiple joints (polyarticular) are involved. In the other hand, infectious conditions like septic arthritis are acute in nature and they usually involve single joints (monoarticular). Crystal induced arthropathies may result in inflammatory joint(s) involvement, mainly are due to uric acid crystal deposition (gout) in articular space. Although, disease course and presence of other systemic manifestations are important for diagnosis but the gold standard method for diagnosis is joint aspiration, fluid analysis, and microscopic evaluation. Imaging might be helpful in certain condition to find the disease chronicity and structural changes in articular and periarticular structures. Prompt treatment is necessary specially for septic and inflammatory conditions to prevent structural joint damage and deformities.

 ==Overview==
+Arthritis (from Greek ''arthro-'', joint + ''-itis'', inflammation; plural: arthritides) could be defined as painful joint damage. It might be as part of a systemic disorder or a single [[joint]] involvement. Arthritis may present as joint pain ([[arthralgia]]), [[swelling]], [[erythema]], warmness, and limitation of movement. It could be classified according to the number of involved joints, presence of inflammation, or duration of symptoms. [[Osteoarthritis]] (also known as degenerative joint disease) is the most common form of arthritis in the United States which involves up to 10% of population older than 60 years. [[Inflammatory]] arthritis is common in systemic [[Autoimmunity|autoimmune disorders]], such as [[rheumatoid arthritis]] and [[systemic lupus erythematosus]] (SLE) and is part of diagnostic criteria for this spectrum of diseases. Disease course in systemic disorders is usually chronic and multiple joints (polyarticular) are involved. In the other hand, infectious conditions like [[septic arthritis]] are acute in nature and they usually involve single joints (monoarticular). [[Crystal arthropathies|Crystal induced arthropathies]] may result in inflammatory joint(s) involvement, mainly are due to [[uric acid]] crystal deposition ([[gout]]) in articular space. Although, disease course and presence of other systemic manifestations are important for diagnosis but the gold standard method for diagnosis is [[Arthrocentesis|joint aspiration]], fluid analysis, and microscopic evaluation. Imaging might be helpful in certain condition to find the disease chronicity and structural changes in articular and periarticular structures. Prompt treatment is necessary specially for septic and inflammatory conditions to prevent structural joint damage and deformities.
-'''Arthritis''' (from Greek ''arthro-'', joint + ''-itis'', inflammation; plural: arthritides) is a group of conditions where there is damage caused to the [[joint]]s of the body. Arthritis is the leading cause of disability in people over the age of 55.
+==Classification==
+===Primary Forms of Arthritis:===
+* [[Osteoarthritis]]
+* [[Rheumatoid arthritis]]
+* [[Septic arthritis]]
+* [[Gout]] and [[Chondrocalcinosis|pseudogout]]
+* [[Juvenile idiopathic arthritis]]
+* [[Still's disease]]
+* [[Ankylosing spondylitis]]
+==Differential Diagnosis==
+=== Differential Diagnosis of Monoarthritis ===
+'''''To review the differential diagnosis of monoarthritis with joint swelling, [[Monoarthritis with joint swelling|click here]]'''.''
-There are many different forms of arthritis, each of which has a different cause. The most common form of arthritis, [[osteoarthritis]] (also known as degenerative joint disease) occurs following trauma to the joint, following an infection of the joint or simply as a result of aging. Furthermore, there is emerging evidence that abnormal anatomy may contribute to early development of osteoarthritis. Other forms of arthritis are [[rheumatoid arthritis]] and [[psoriatic arthritis]], which are [[autoimmune disorder|autoimmune diseases]] in which the body is attacking itself. [[Septic arthritis]] is caused by joint [[infection]]. [[gout|Gouty arthritis]] is caused by deposition of [[uric acid]] crystals in the joint that results in subsequent inflammation. Additionally, there is a less common form of gout that is caused by the formation of rhomboidal shaped crystals of calcium pyrophosphate.  This form of gout is known as [[Calcium pyrophosphate deposition disease|pseudogout]].

-==History==
+'''''To review the differential diagnosis of monoarthritis with weight loss, [[Monoarthritis with weight loss|click here]]'''.''
-While evidence of primary ankle (kaki) osteoarthritis has been discovered in dinosaurs, the first known traces of human arthritis date back as far as 4500 BC. It was noted in skeletal remains of Native Americans found in Tennessee and parts of what is now Olathe, Kansas. Evidence of arthritis has been found throughout history, from Ötzi, a mummy (circa 3000 BC) found along the border of modern Italy and Austria, to the Egyptian mummies circa 2590 BC.
+'''''To review the differential diagnosis of monoarthritis with claudication, [[Monoarthritis with claudication|click here]]'''.''
-In 1715 William Musgrave published the second edition of his most important medical work ''De arthritide symptomatica'' which concerned arthritis and its effects.<ref name=ODNB>Alick Cameron, ‘Musgrave, William (1655–1721)’, Oxford Dictionary of National Biography, Oxford University Press, Sept 2004</ref>

-==Medical History and Physical Examination==
+'''''To review the differential diagnosis of monoarthritis with local erythema, [[Monoarthritis with local erythema|click here]]'''.''
-All arthritides feature [[Pain and nociception|pain]]. Patterns of pain differ among the arthritides and the location.
+'''''To review the differential diagnosis of monoarthritis with joint swelling and fever, [[Monoarthritis with joint swelling and fever|click here]]'''.''
-[[Osteoarthritis]] is classically worse at night or following rest. [[Rheumatoid arthritis]] is generally worse in the morning; in the early stages, patients often do not have symptoms following their morning shower. In elderly people and children, pain may not be the main feature, and the patient simply moves less (elderly) or refuses to use the affected limb (children).

-Elements of the history of the pain (onset, number of joints and which involved, duration, aggravating and relieving factors) all guide diagnosis. Physical examination typically confirms diagnosis. Radiographs are often used to follow progression or assess severity in a more quantitative manner.

-Another form of non-drug treatment that does have a body of proper research to support its efficacy is marine oil, from both fish and the New Zealand green-lipped mussel (Perna canaliculus). Diets high in marine oils from cold-water fish such as salmon, mackerel, and tuna have been shown to reduce the inflammation of joint conditions such as arthritis. Massage on joints with [[neem oil]] has reported improvement in chronic and acute cases.
