Fasciitis
Fasciitis is an inflammation of the fascia, which is the connective tissue surrounding muscles, blood vessels and nerves. In particular, it often involves one of the following diseases: * Necrotizing fasciitis * Plantar fasciitis * Ischemic fasciitis, classified by the World Health Organization, 2020, as a specific tumor form in the category of fibroblastic and myofibroblastic tumors. * Eosinophilic fasciitis * Paraneoplastic fasciitis References External links Inflammations {{Musculoskeletal-disease-stub ...

Plantar Fasciitis
Plantar fasciitis or plantar heel pain is a disorder of the plantar fascia, which is the connective tissue that supports the Arches of the foot, arch of the foot. It results in pain in the heel and Sole (foot), bottom of the foot that is usually most severe with the first steps of the day or following a period of rest. Pain is also frequently brought on by dorsiflexion, bending the foot and toes up towards the shin. The pain typically comes on gradually, and it affects both feet in about one-third of cases. The cause of plantar fasciitis is not entirely clear. Risk factors include overuse, such as from long periods of standing, an increase in exercise, and obesity. It is also associated with pronation of the foot, inward rolling of the foot, a tight Achilles tendon, and a sedentary lifestyle. It is unclear if calcaneal spur, heel spurs have a role in causing plantar fasciitis even though they are commonly present in people who have the condition. Plantar fasciitis is a disorder ...

Necrotizing Fasciitis
Necrotizing fasciitis (NF), also known as flesh-eating disease, is an infection that kills the body's soft tissue. It is a serious disease that begins and spreads quickly. Symptoms include red or purple or black skin, swelling, severe pain, fever, and vomiting. The most commonly affected areas are the limb (anatomy), limbs and perineum. Bacterial infection is by far the most common cause of necrotizing fasciitis. Despite being called a "flesh-eating disease", bacteria do not eat human tissue. Rather, they release toxins that cause tissue death. Typically, the infection enters the body through a break in the skin such as a cut or burn. Risk factors include recent trauma or surgery and immunodeficiency, a weakened immune system due to diabetes or cancer, obesity, alcoholism, intravenous drug use, and peripheral artery disease. It does not usually spread between people. The disease is classified into four types, depending on the infecting organisms. Medical imaging is often helpfu ...

Eosinophilic Fasciitis
Eosinophilic fasciitis (), also known as Shulman's syndrome or diffuse fasciitis with eosinophilia, is an inflammatory disease that affects the fascia, other connective tissues, surrounding muscles, blood vessels and nerves. Unlike other forms of fasciitis, eosinophilic fasciitis is typically self-limited and confined to the arms and legs, although it can require treatment with corticosteroids, and some cases are associated with aplastic anemia. The condition was first characterized by Shulman in 1974, but it is not yet known whether it is actually a distinct condition or merely a variant presentation of another syndrome. The presentation is similar to that of scleroderma or systemic sclerosis. However, unlike scleroderma, eosinophilic fasciitis affects the deeper fascial layers, rather than the dermis; the characteristic and severe effects of scleroderma and systemic sclerosis, such as Raynaud's syndrome, involvement of the extremities, prominent small blood vessels (telangiectas ...

Ischemic Fasciitis
Ischemic fasciities (IF), also termed atypical decubital fibroplasia or decubital ischemic fasciitis, is a rare pseudosarcomatous (i.e. easily mistaken for a sarcoma) tumor. It was first described by E. A. Montgomery et al. in 1992. This tumor typically forms in the subcutaneous tissues (i.e. lower most tissue layer of the skin) that overlie bony protuberances such as a hip in individuals who are debilitated and bed-ridden. Microscopically, IF lesions consist of proliferating, atypical fibroblasts and/or myofibroblasts. The lesions were initially regarded as non-neoplastic proliferation responses of these cell types to long-term tissue pressure or trauma. More recently, however, the World Health Organization, 2020, defined IF lesions as neoplasms, i.e. tissue growths which are uncoordinated with that of the normal surrounding tissue and persist in growing even if the original trigger for their development is removed. The Organization formally classified IF lesions as belonging to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fibroblastic And Myofibroblastic Tumors
Fibroblastic and myofibroblastic tumors (FMTs) are tumors which develop from the mesenchymal stem cells which differentiate into fibroblasts (the most common cell type in connective tissue) and/or the myocytes/ myoblasts that differentiate into muscle cells. FMTs are a heterogeneous group of soft tissue neoplasms (i.e. abnormal and excessive tissue growths). The World Health Organization (2020) defined tumors as being FMTs based on their morphology and, more importantly, newly discovered abnormalities in the expression levels of key gene products made by these tumors' neoplastic cells. Histopathologically, FMTs consist of neoplastic connective tissue cells which have differented into cells that have microscopic appearances resembling fibroblasts and/or myofibroblasts. The fibroblastic cells are characterized as spindle-shaped cells with inconspicuous nucleoli that express vimentin, an intracellular protein typically found in mesenchymal cells, and CD34, a cell surface membra ...

Fascia
A fascia (; : fasciae or fascias; adjective fascial; ) is a generic term for macroscopic membranous bodily structures. Fasciae are classified as superficial, visceral or deep, and further designated according to their anatomical location. The knowledge of fascial structures is essential in surgery, as they create borders for infectious processes (for example Psoas abscess) and haematoma. An increase in pressure may result in a compartment syndrome, where a prompt fasciotomy may be necessary. For this reason, profound descriptions of fascial structures are available in anatomical literature from the 19th century. Function Fasciae were traditionally thought of as passive structures that transmit mechanical tension generated by muscular activities or external forces throughout the body. An important function of muscle fasciae is to reduce friction of muscular force. In doing so, fasciae provide a supportive and movable wrapping for nerves and blood vessels as they pass thro ...

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 ...

Paraneoplastic Fasciitis
A paraneoplastic syndrome is a syndrome (a set of signs and symptoms) that is the consequence of a tumor in the body (usually a cancerous one). It is specifically due to the production of chemical signaling molecules (such as hormones or cytokines) by tumor cells or by an immune response against the tumor. Unlike a mass effect, it is not due to the local presence of cancer cells. Paraneoplastic syndromes are typical among middle-aged to older people, and they most commonly occur with cancers of the lung, breast, ovaries or lymphatic system (a lymphoma). Sometimes, the symptoms of paraneoplastic syndromes show before the diagnosis of a malignancy, which has been hypothesized to relate to the disease pathogenesis. In this paradigm, tumor cells express tissue-restricted antigens (e.g., neuronal proteins), triggering an anti-tumor immune response which may be partially or, rarely, completely effective in suppressing tumor growth and symptoms. Patients then come to clinical attention ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
