Arthropathy
An arthropathy is a disease of a joint. Types Arthritis is a form of arthropathy that involves inflammation of one or more joints, while the term arthropathy may be used regardless of whether there is inflammation or not. Joint diseases can be classified as follows: * Arthritis :* Infectious arthritis ::* Septic arthritis (infectious) ::* Tuberculosis arthritis ::* Reactive arthritis (indirectly) :*Noninfectious arthritis ::* Seronegative spondyloarthropathy: :::* Psoriatic arthritis :::* Ankylosing spondylitis ::*Rheumatoid arthritis: :::* Felty's syndrome ::*Juvenile idiopathic arthritis ::* Adult-onset Still's disease ::* Crystal arthropathy :::*Gout :::* Chondrocalcinosis ::* Osteoarthritis * Hemarthrosis (joint bleeding) * Synovitis is the medical term for inflammation of the synovial membrane. * Joint dislocation With ''arthropathy'' in the name * '' Reactive arthropathy'' (M02-M03) is caused by an infection, but not a direct infection of the synovial space.

Enteropathic Arthropathy
Enteropathic arthropathy, commonly referred to as enteropathic arthritis, is a type of arthritis linked to Crohn's disease, ulcerative colitis, and chronic inflammatory bowel diseases. Along with reactive arthritis, psoriatic arthritis, and idiopathic ankylosing spondylitis, this type of arthritis is categorized as a seronegative spondyloarthropathy. Other gastrointestinal disorders like Whipple's disease, celiac disease, and intestinal bypass surgery for severe obesity can also cause joint involvement. The pathogenesis of arthritis in these conditions is likely influenced by immunologic, genetic, and abnormal bowel permeability factors, though the precise mechanisms are still unknown. Signs and symptoms Historically, there have been two main patterns of joint involvement with enteropathic arthritis: axial involvement, which includes sacroiliitis with or without spondylitis resembling idiopathic ankylosing spondylitis, and peripheral arthritis. Additional conditions that may ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crystal Arthropathy
Crystal arthropathy is a class of joint disorders (called '' arthropathy'') that is characterized by the accumulation of tiny crystals in one or more joints. Polarizing microscopy and the application of other crystallographic techniques have improved the identification of different microcrystals including monosodium urate, calcium pyrophosphate dihydrate, calcium hydroxyapatite, and calcium oxalate. Types Causes *Deposition of crystals in joints * Calcium pyrophosphate dihydrate crystal formation: **Increased production of inorganic pyrophosphate **Decreased levels of pyrophosphatase in cartilage **Decreased levels of cartilage glycosaminoglycans **Hyperparathyroidism ** Hemochromatosis ** Hypophosphatasia ** Hypomagnesemia *Hydroxyapatite deposition: ** Tissue damage **Hyperparathyroidism **Hypercalcemia ** Hyperphosphatemia *Calcium oxalate deposition: **Enhanced production of oxalic acid due to enzyme defect **Poor excretion of oxalic acid in kidney failure **Excessive ...

Psoriatic Arthritis
Psoriatic arthritis (PsA) is a long-term inflammatory arthritis that may occur in some people affected by the autoimmune disease psoriasis. The classic features of psoriatic arthritis include dactylitis (sausage-like swelling of the fingers), skin lesions, and nail lesions. Lesions of the nails may include small depressions in the nail (pitting), thickening of the nails, and detachment of the nail from the nailbed. Skin lesions consistent with psoriasis (e.g., red, scaly, and itchy plaques) frequently occur before the onset of psoriatic arthritis but psoriatic arthritis can precede the rash in 15% of affected individuals. It is classified as a type of seronegative spondyloarthropathy. Genetics are thought to be strongly involved in the development of psoriatic arthritis. Obesity and certain forms of psoriasis are thought to increase the risk. Psoriatic arthritis affects up to 30% of people with psoriasis. It occurs in both children and adults. Some people with Ps ...

Rheumatology
Rheumatology () is a branch of medicine devoted to the diagnosis and management of disorders whose common feature is inflammation in the bones, muscles, joints, and internal organs. Rheumatology covers more than 100 different complex diseases, collectively known as rheumatic diseases, which includes many forms of arthritis as well as lupus and Sjögren syndrome, Sjögren's syndrome. Physician, Doctors who have undergone formal training in rheumatology are called rheumatologists. Many of these diseases are now known to be disorders of the immune system, and rheumatology has significant overlap with immunology, the branch of medicine that studies the immune system. Rheumatologist A rheumatologist is a physician who specializes in the field of medical sub-specialty called rheumatology. A rheumatologist holds a board certification after specialized training. In the United States, training in this field requires four years of undergraduate school, four years of medical school, a ...

Ankylosing Spondylitis
Ankylosing spondylitis (AS) is a type of arthritis from the disease spectrum of axial spondyloarthritis. It is characterized by long-term inflammation of the joints of the spine, typically where the spine joins the pelvis. With AS, eye and bowel problems—as well as back pain—may occur. Joint mobility in the affected areas sometimes worsens over time. Ankylosing spondylitis is believed to involve a combination of genetic and environmental factors. More than 90% of people affected in the UK have a specific human leukocyte antigen known as the HLA-B27 antigen. The underlying mechanism is believed to be autoimmune or autoinflammatory. Diagnosis is based on symptoms with support from medical imaging and blood tests. AS is a type of seronegative spondyloarthropathy, meaning that tests show no presence of rheumatoid factor (RF) antibodies. There is no cure for AS. Treatments may include medication, physical therapy, and surgery. Medication therapy focuses on relieving the pai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemarthrosis
Hemarthrosis is a bleeding into joint spaces. It is a common feature of hemophilia. Causes It usually follows injury but occurs mainly in patients with a predisposition to hemorrhage such as those being treated with warfarin (or other anticoagulants) and patients with hemophilia. It can be associated with knee joint arthroplasty. It has also been reported as a part of hemorrhagic syndrome in the Crimean-Congo Hemorrhagic Fever, suggesting a viral cause to the bleeding in a joint space. Diagnosis Hemarthrosis is diagnosed through the methods listed below: A physical examination is the first step, with the joints of the patient moved and bent to study possible loss of functioning. Synovial fluid analysis is another method to diagnose Hemarthrosis. It involves a small needle being inserted into the joint to draw the fluid. Reddish-colored hue of the sample is an indication of the blood being present. Imaging tests are normally done. The tests also include MRI, ultrasound an ...

Gout
Gout ( ) is a form of inflammatory arthritis characterized by recurrent attacks of pain in a red, tender, hot, and Joint effusion, swollen joint, caused by the deposition of needle-like crystals of uric acid known as monosodium urate crystals. Pain typically comes on rapidly, reaching maximal intensity in less than 12 hours. The Metatarsophalangeal joint, joint at the base of the Hallux, big toe is affected (''Podagra'') in about half of cases. It may also result in Tophus, tophi, kidney stones, or Urate nephropathy, kidney damage. Gout is due to persistently elevated levels of uric acid (urate) in the blood (hyperuricemia). This occurs from a combination of diet, other health problems, and genetic factors. At high levels, uric acid crystallizes and the crystals deposit in joints, tendons, and surrounding tissues, resulting in an attack of gout. Gout occurs more commonly in those who regularly drink beer or sugar-sweetened beverages; eat foods that are high in purines such ...

Reactive Arthropathy
Reactive arthritis, previously known as Reiter's syndrome, is a form of inflammatory arthritis that develops in response to an infection in another part of the body (cross-reactivity). Coming into contact with bacteria and developing an infection can trigger the disease. By the time a person presents with symptoms, the "trigger" infection has often been cured or is in remission in chronic cases, thus making determination of the initial cause difficult. The manifestations of reactive arthritis include the following triad of symptoms: inflammatory arthritis of large joints, inflammation of the eyes in the form of conjunctivitis or uveitis, and urethritis in men or cervicitis in women. Arthritis occurring alone following sexual exposure or enteric infection is also known as reactive arthritis. Affected people may present with mucocutaneous lesions, as well as psoriasis-like skin lesions such as circinate balanitis, and keratoderma blennorrhagicum. Enthesitis can involve the Achi ...

Osteoarthritis
Osteoarthritis is a type of degenerative joint disease that results from breakdown of articular cartilage, joint cartilage and underlying bone. A form of arthritis, it is believed to be the fourth leading cause of disability in the world, affecting 1 in 7 adults in the United States alone. The most common symptoms are joint pain and Joint stiffness, stiffness. Usually the symptoms progress slowly over years. Other symptoms may include joint effusion, joint swelling, decreased range of motion, and, when the back is affected, weakness or numbness of the arms and legs. The most commonly involved joints are the two near the ends of the fingers and the joint at the base of the thumbs, the knee and hip joints, and the joints of the neck and lower back. The symptoms can interfere with work and normal daily activities. Unlike some other types of arthritis, only the joints, not internal organs, are affected. Possible causes include previous joint injury, abnormal joint or limb development ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Juvenile Idiopathic Arthritis
Juvenile idiopathic arthritis (JIA), formerly known as juvenile rheumatoid arthritis (JRA), is the most common chronic rheumatic disease of childhood, affecting approximately 3.8 to 400 out of 100,000 children. ''Juvenile'', in this context, refers to disease onset before 16 years of age, while ''idiopathic'' refers to a condition with no defined cause, and ''arthritis'' is inflammation within the joint. JIA is an autoimmune, noninfective, inflammatory joint disease, the cause of which remains poorly understood. It is characterised by chronic joint inflammation. JIA is a subset of childhood arthritis, but unlike other, more transient forms of childhood arthritis, JIA persists for at least six weeks, and in some children is a lifelong condition. It differs significantly from forms of arthritis commonly seen in adults (osteoarthritis, rheumatoid arthritis), in terms of cause, disease associations, and prognosis. The prognosis for children with JIA has improved dramatically over re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
