Urticarial Vasculitis
Urticarial vasculitis (also known as "chronic urticaria as a manifestation of venulitis", "hypocomplementemic urticarial vasculitis syndrome", "hypocomplementemic vasculitis" and "unusual lupus-like syndrome") is a skin condition characterized by fixed urticarial lesions that appear histologically as a vasculitis. Mechanism Antibodies are usually raised against foreign proteins, such as those made by a replicating virus or invading bacterium. Virus or bacteria with antibodies opsonized or "stuck" to them highlight them to other cells of the immune system for clearance. Antibodies against self proteins are known as autoantibodies, and are not found in healthy individuals. These autoantibodies can be used to detect certain diseases. C1q C1q is an integral component within the complement pathway – a complicated cascade of protein interactions, culminating in an immune response against a broad variety of pathogens. The anti-C1q antibodies found in patients with hypocomplementemi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Histologically
Histology, also known as microscopic anatomy or microanatomy, is the branch of biology that studies the microscopic anatomy of biological tissue (biology), tissues. Histology is the microscopic counterpart to gross anatomy, which looks at larger structures visible without a microscope. Although one may divide microscopic anatomy into ''organology'', the study of organs, ''histology'', the study of tissues, and ''cytology'', the study of cell (biology), cells, modern usage places all of these topics under the field of histology. In medicine, histopathology is the branch of histology that includes the microscopic identification and study of diseased tissue. In the field of paleontology, the term paleohistology refers to the histology of fossil organisms. Biological tissues Animal tissue classification There are four basic types of animal tissues: muscle tissue, nervous tissue, connective tissue, and epithelial tissue. All animal tissues are considered to be subtypes of these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycophenolate
Mycophenolic acid is an immunosuppressant medication used to prevent rejection following organ transplantation and to treat autoimmune conditions such as Crohn's disease and lupus. Specifically it is used following kidney, heart, and liver transplantation. It can be given by mouth or by injection into a vein. It comes as mycophenolate sodium and mycophenolate mofetil. Common side effects include nausea, infections, and diarrhea. Other serious side effects include an increased risk of cancer, progressive multifocal leukoencephalopathy, anemia, and gastrointestinal bleeding. Use during pregnancy may harm the baby. It works by blocking inosine monophosphate dehydrogenase (IMPDH), which is needed by lymphocytes to make guanosine. Mycophenolic acid was initially discovered by Italian Bartolomeo Gosio in 1893. It was rediscovered in 1945 and 1968. It was approved for medical use in the United States in 1995 following the discovery of its immunosuppressive properties in the 19 ...

ILDS
The International League of Dermatological Societies (ILDS) is a non-governmental organization that works closely with the World Health Organization. It was founded in 1935, but because of World War II no congresses were held until 1952. It is governed by the International Committee of Dermatology. The ILDS is the parent organization of the International Foundation for Dermatology, founded in 1987. After the publication of ICD-10, the ILDS produced a series of compatible extensions for use in dermatology Dermatology is the branch of medicine dealing with the Human skin, skin.''Random House Webster's Unabridged Dictionary.''

List Of Cutaneous Conditions
Many skin conditions affect the human integumentary system—the organ system covering the entire surface of the Human body, body and composed of Human skin, skin, hair, Nail (anatomy), nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis (skin), epidermis, dermis, and subcutaneous tissue. The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin.Burns, Tony; ''et al''. (2006) ''Rook's Textbook of Dermatology CD-ROM''. Wiley-Blackwell. . Within the latter type, the hairs occur in structures called pilosebaceous units, each with hair follicle, sebaceous gland, and associated arrector pili muscle. Embryology, In the embryo, the epidermis, hair, and glands form from the ectod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cutaneous Small-vessel Vasculitis
Cutaneous small-vessel vasculitis (CSVV) is inflammation of small blood vessels, usually accompanied by small lumps beneath the skin. The condition is also known as hypersensitivity vasculitis, cutaneous leukocytoclastic vasculitis, hypersensitivity angiitis, cutaneous leukocytoclastic angiitis, cutaneous necrotizing vasculitis and cutaneous necrotizing venulitis, It is the most common form of vasculitis seen in clinical practice, usually caused by inflammation of post-capillary venules in the dermis). "Leukocytoclastic" (literally meaning 'leukocyte-destroying') refers to the damage caused by nuclear debris from infiltrating neutrophils in and around the vessels. Signs and symptoms Skin lesions Initially red to pink, flat spots (formally, "macules") and raised bumps (formally, "papules") may be seen on the skin. Once fully developed, the classic appearance is "non-blanching, palpable purpura". This appears as deep red to purple spots that feel raised to the touch. Purpu ...

Fat, Sick And Nearly Dead
''Fat, Sick and Nearly Dead'' is a 2010 American documentary film which follows the 60-day journey of Australian Joe Cross across the United States as he follows a juice fast to regain his health under the care of Joel Fuhrman, Nutrition Research Foundation's Director of Research. Summary The feature-length film follows Cross, who was depressed, weighed 310 lbs, suffered from a serious autoimmune disease, and was on steroids at the start of the film, as he embarks on a juice fast. Cross and Robert Mac, co-creators of the film, both serve on the Nutrition Research Foundation's Advisory Board. Following his fast and the adoption of a plant-based diet, Cross states in a press release that he lost 100 pounds and discontinued all medications. During his road-trip Cross meets Phil Staples, a morbidly obese truck driver from Sheldon, Iowa, in a truck stop in Arizona and inspires him to try juice fasting. A sequel to the first film, ''Fat, Sick and Nearly Dead 2'', was released in 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vasculitis
Vasculitis is a group of disorders that destroy blood vessels by inflammation. Both artery, arteries and veins are affected. Lymphangitis (inflammation of lymphatic vessels) is sometimes considered a type of vasculitis. Vasculitis is primarily caused by white blood cell, leukocyte migration and resultant damage. Although both occur in vasculitis, inflammation of veins (phlebitis) or arteries (arteritis) on their own are separate entities. Signs and symptoms The clinical presentation of the various vasculitides on the skin and internal organs is mostly determined by the diameter or size of the vessels mainly affected. Non-specific symptoms are common and include fever, headache, fatigue, myalgia, weight loss, and arthralgia. All forms of vasculitis, even large vessel vasculitides, may cause skin manifestations. The most common skin manifestations include purpura, Nodule (dermatology), nodules, livedo reticularis, Ulcer (dermatology), skin ulcers, and purpuric Hives, urticaria. ...
