Oral Mite Anaphylaxis
Oral mite anaphylaxis (OMA), also known as pancake syndrome, is severe allergic reaction triggered by the ingestion of food contaminated with specific mites. The condition is associated with the consumption of wheat or maize flour that has been improperly stored in humid environments, leading to mite infestation. Symptoms can range from mild allergic reactions to severe anaphylaxis, often occurring shortly after ingestion of contaminated food. The disease name comes from reports of people becoming ill after eating pancakes made from contaminated wheat or corn (maize) flour. Signs and Symptoms Oral Mite Anaphylaxis (OMA) typically presents with acute allergic symptoms emerging within 10 to 240 minutes following the consumption of mite-contaminated flour. These symptoms affect multiple organ systems, often progressing rapidly. Respiratory manifestations are common and may include stridor, wheezing, sneezing, and nasal obstruction, which can worsen over time. Angioedema involving the ...

Food Allergies
A food allergy is an abnormal immune response to food. The symptoms of the allergic reaction may range from mild to severe. They may include itchiness, swelling of the tongue, vomiting, diarrhea, hives, trouble breathing, or low blood pressure. This typically occurs within minutes to several hours of exposure. When the symptoms are severe, it is known as anaphylaxis. A food intolerance and food poisoning are separate conditions, not due to an immune response. Common foods involved include cow's milk, peanuts, eggs, shellfish, fish, tree nuts, soy, wheat, and sesame. The common allergies vary depending on the country. Risk factors include a family history of allergies, vitamin D deficiency, obesity, and high levels of cleanliness. Allergies occur when immunoglobulin E (IgE), part of the body's immune system, binds to food molecules. A protein in the food is usually the problem. This triggers the release of inflammatory chemicals such as histamine. Diagnosis is usuall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leukotriene
Leukotrienes are a family of eicosanoid inflammation, inflammatory mediators produced in leukocytes by the redox, oxidation of arachidonic acid (AA) and the essential fatty acid eicosapentaenoic acid (EPA) by the enzyme arachidonate 5-lipoxygenase. Leukotrienes use lipid signaling to convey information to either the cell producing them (autocrine signaling) or neighboring cells (paracrine signaling) in order to regulate immune responses. The production of leukotrienes is usually accompanied by the production of histamine and prostaglandins, which also act as inflammatory mediators. One of their roles (specifically, Leukotriene D4, leukotriene D4) is to trigger contractions in the smooth muscles lining the bronchioles; their overproduction is a major cause of inflammation in asthma and allergic rhinitis. Leukotriene antagonists are used to treat these disorders by inhibiting the production or activity of leukotrienes. History and name The name ''leukotriene'', introduced by ...

Mast Cell
A mast cell (also known as a mastocyte or a labrocyte) is a resident cell of connective tissue that contains many granules rich in histamine and heparin. Specifically, it is a type of granulocyte derived from the myeloid stem cell that is a part of the immune and neuroimmune systems. Mast cells were discovered by Friedrich von Recklinghausen and later rediscovered by Paul Ehrlich in 1877. Although best known for their role in allergy and anaphylaxis, mast cells play an important protective role as well, being intimately involved in wound healing, angiogenesis, immune tolerance, defense against pathogens, and vascular permeability in brain tumors. The mast cell is very similar in both appearance and function to the basophil, another type of white blood cell. Although mast cells were once thought to be tissue-resident basophils, it has been shown that the two cells develop from different hematopoietic lineages and thus cannot be the same cells. Structure Mast cells ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nonsteroidal Anti-inflammatory Drug
Non-steroidal anti-inflammatory drugs (NSAID) are members of a Indication (medicine), therapeutic drug class which Analgesic, reduces pain, Anti-inflammatory, decreases inflammation, Antipyretic, decreases fever, and Antithrombotic, prevents blood clots. Side effects depend on the specific drug, its dose and duration of use, but largely include an increased risk of Stomach ulcers, gastrointestinal ulcers and bleeds, heart attack, and kidney disease. The term ''non-steroidal'', common from around 1960, distinguishes these drugs from corticosteroids, another class of anti-inflammatory drugs, which during the 1950s had acquired a bad reputation due to overuse and side-effect problems after their introduction in 1948. NSAIDs work by inhibiting the activity of cyclooxygenase enzymes (the COX-1 and COX-2 isozyme, isoenzymes). In cells, these enzymes are involved in the synthesis of key biological mediators, namely prostaglandins, which are involved in inflammation, and thromboxanes, ...

Allergen Immunotherapy
Allergen immunotherapy, also known as desensitization or hypo-sensitization, is a medical treatment for environmental allergies (such as insect bites) and asthma. Immunotherapy involves exposing people to larger and larger amounts of allergens in an attempt to change the immune system's response. Meta-analyses have found that injections of allergens under the skin are effective in the treatment of allergic rhinitis in children and in asthma. The benefits may last for years after treatment is stopped. It is generally safe and effective for allergic rhinitis, allergic conjunctivitis, allergic forms of asthma, and stinging insects. The evidence also supports the use of sublingual immunotherapy against rhinitis and asthma, but it is less strong. In this form the allergen is given under the tongue and people often prefer it to injections. Immunotherapy is not recommended as a stand-alone treatment for asthma. Side effects during sublingual immunotherapy treatment are usually lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anaphylaxis
Anaphylaxis (Greek: 'up' + 'guarding') is a serious, potentially fatal allergic reaction and medical emergency that is rapid in onset and requires immediate medical attention regardless of the use of emergency medication on site. It typically causes more than one of the following: an itchy rash, throat closing due to swelling that can obstruct or stop breathing; severe tongue swelling that can also interfere with or stop breathing; shortness of breath, vomiting, lightheadedness, loss of consciousness, low blood pressure, and medical shock. These symptoms typically start in minutes to hours and then increase very rapidly to life-threatening levels. Urgent medical treatment is required to prevent serious harm and death, even if the patient has used an epinephrine autoinjector or has taken other medications in response, and even if symptoms appear to be improving. Cause, mechanism, and diagnosis Common causes include allergies to insect bites and stings, allergies to fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NSAID Hypersensitivity Reactions
NSAID (or nonsteroidal anti-inflammatory drug) hypersensitivity reactions encompass a broad range of allergic or allergic-like symptoms that occur within minutes to hours after ingesting aspirin or other NSAID nonsteroidal anti-inflammatory drugs. Hypersensitivity drug reactions differ from drug toxicity reactions in that drug toxicity reactions result from the pharmacological action of a drug, are dose-related, and can occur in any treated individual. Hypersensitivity reactions are idiosyncratic reactions to a drug. Although the term NSAID was introduced to signal a comparatively low risk of adverse effects, NSAIDs do evoke a broad range of hypersensitivity syndromes. These syndromes have recently been classified by the European Academy of Allergy and Clinical Immunology Task Force on NSAIDs Hypersensitivity. __TOC__ Classification The classification organizes the hypersensitivity reactions to NSAIDs into the following five categories: # NSAIDs-exacerbated respiratory diseas ...

Dermatitis
Dermatitis is a term used for different types of skin inflammation, typically characterized by itchiness, redness and a rash. In cases of short duration, there may be small blisters, while in long-term cases the skin may become thickened. The area of skin involved can vary from small to covering the entire body. Dermatitis is also called eczema but the same term is often used for the most common type of skin inflammation, atopic dermatitis. The exact cause of the condition is often unclear. Cases may involve a combination of allergy and poor venous return. The type of dermatitis is generally determined by the person's history and the location of the rash. For example, irritant dermatitis often occurs on the hands of those who frequently get them wet. Allergic contact dermatitis occurs upon exposure to an allergen, causing a hypersensitivity reaction in the skin. Prevention of atopic dermatitis is typically with essential fatty acids, and may be treated with moistu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suidasia Pontifica
''Suidasia'' is a genus of mites in the family Suidasiidae and clade Astigmatina. Description The body of ''Suidasia'' mites has various patterns. If small rounded protuberances are present, these are coalescent and at least some are unequal. The dorsal surface is covered in smooth setae. The prodorsum has external vertical setae ''ve'' on the sides of the prodorsal sclerite and near the transverse level of setae ''vi''. The supracoxal setae are lanceolate in shape and have fimbriate margins. The hysterosomal setae are short and do not reach the bases of next setae. On the ventral surface of the body, the anus is positioned near the pretarsal margin. The ventral subcapitulum is without external ridges. Each leg ends in pretarsi ambulacra that are not greatly expanded, and in empodial claws that are simple. The tarsi have solenidion ''ω2'' and setae ''e'' and ''f'', the latter two both being filiform. Ecology ''Suidasia'' are generalists found in various habitats, such a ...
