Arthropathies
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.

Joint
A joint or articulation (or articular surface) is the connection made between bones, ossicles, or other hard structures in the body which link an animal's skeletal system into a functional whole.Saladin, Ken. Anatomy & Physiology. 7th ed. McGraw-Hill Connect. Webp.274/ref> They are constructed to allow for different degrees and types of movement. Some joints, such as the knee, elbow, and shoulder, are self-lubricating, almost frictionless, and are able to withstand compression and maintain heavy loads while still executing smooth and precise movements. Other joints such as suture (joint), sutures between the bones of the skull permit very little movement (only during birth) in order to protect the brain and the sense organs. The connection between a tooth and the jawbone is also called a joint, and is described as a fibrous joint known as a gomphosis. Joints are classified both structurally and functionally. Joints play a vital role in the human body, contributing to movement, sta ... [...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 ...

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] |
Bone Erosion
Bone erosion is the loss of bone from disease processes. Erosive arthritis is joint inflammation (arthritis) with bone destruction, and such conditions include rheumatoid arthritis. Bone erosion is the loss of bone in a certain area, rather than a change in bone density, which is found in osteoporosis. Surprisingly, bone erosion is not common in 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, affect ..., although there is a subtype of osteoarthritis (erosive osteoarthritis) that may result in bone erosion.

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 ...

Colitis
Colitis is swelling or inflammation Inflammation (from ) is part of the biological response of body tissues to harmful stimuli, such as pathogens, damaged cells, or irritants. The five cardinal signs are heat, pain, redness, swelling, and loss of function (Latin ''calor'', '' ... of the large intestine (colon (anatomy), colon). Colitis may be acute (medicine), acute and self-limited or chronic condition, long-term. It broadly fits into the category of digestive diseases. In a medical context, the label ''colitis'' (without qualification) is used if: * The cause of the inflammation in the colon is undetermined; for example, ''colitis'' may be applied to ''Crohn's disease'' at a time when the diagnosis is unknown, or * The context is clear; for example, an individual with ulcerative colitis is talking about their disease with a physician who knows the diagnosis. Signs and symptoms The sign (medicine), signs and symptoms of colitis are quite variable and dependent on the ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Infection
An infection is the invasion of tissue (biology), tissues by pathogens, their multiplication, and the reaction of host (biology), host tissues to the infectious agent and the toxins they produce. An infectious disease, also known as a transmissible disease or communicable disease, is an Disease#Terminology, illness resulting from an infection. Infections can be caused by a wide range of pathogens, most prominently pathogenic bacteria, bacteria and viruses. Hosts can fight infections using their immune systems. Mammalian hosts react to infections with an Innate immune system, innate response, often involving inflammation, followed by an Adaptive immune system, adaptive response. Treatment for infections depends on the type of pathogen involved. Common medications include: * Antibiotics for bacterial infections. * Antivirals for viral infections. * Antifungals for fungal infections. * Antiprotozoals for protozoan infections. * Antihelminthics for infections caused by parasi ...

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 ...

Joint Dislocation
A joint dislocation, also called luxation, occurs when there is an abnormal separation in the joint, where two or more bones meet. A partial dislocation is referred to as a subluxation. Dislocations are commonly caused by sudden Trauma (medicine), trauma to the joint like during a car accident or fall. A joint dislocation can damage the surrounding ligaments, tendons, muscles, and nerves. Dislocations can occur in any major joint (shoulder, knees, hips) or minor joint (toes, fingers). The most common joint dislocation is a shoulder dislocation. The treatment for joint dislocation is usually by closed reduction (orthopedic surgery), reduction, that is, skilled manipulation to return the bones to their normal position. Only trained medical professionals should perform reductions since the manipulation can cause injury to the surrounding soft tissue, nerves, or vascular structures. Signs and Symptoms The following symptoms are common with any type of dislocation. * Intense pain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
