Urticaria, commonly known as wheal, is a common skin disease. Temporary inflammatory hyperemia and massive fluid exudation are caused by many factors. Causing local edema damage. It appears and quickly subsides, accompanied by severe itching. There may be fever, abdominal pain, diarrhea or other systemic symptoms. It can be divided into acute urticaria, chronic urticaria, angioneurotic edema and papular urticaria.
Urticaria is a common allergic skin disease. When exposed to allergens, red plaques of different shapes and sizes will appear in unspecified parts of the body. These patches will itch. If you don't stop touching the rash allergen and treat it, the rash and itching will get worse.
Classification and symptoms of urticaria:
1, urticaria in children
Urticaria is not only a frequently-occurring disease in adults, but also a frequently-occurring and common disease in children. The characteristics of children's urticaria are: most of them are caused by allergic reactions, and the common suspicious reasons are food first, followed by infection. Because of different ages and diets, the causes of urticaria are different. For example, infants are mainly fed with breast milk, milk and dairy products, and the causes of urticaria are mostly related to additives of milk and dairy products.
With the growth of age, infants began to increase complementary food. At this time, eggs, meat floss, fish floss, fruit juice, vegetables and fruits can all be the cause of allergies. Preschool and school-age children often like to eat snacks. There are many kinds of snacks and dinner foods, so the probability of food allergy increases, such as nuts, fish, crabs, shrimps, peanuts, eggs, strawberries, apples, plums, oranges, all kinds of cold drinks, beverages and chocolates.
Children aged 2-7 lack autonomy, and when they are outdoors, outdoors, under trees or under street lamps at night, they are often easily bitten by insects, or come into contact with pollen, dust, mites and the fur of pets such as cats and dogs, which are easy to become allergic reasons. Children in childhood and infancy have low resistance and are prone to various infections, so diseases such as suppurative tonsillitis, pharyngitis, enteritis and upper respiratory tract infection can be the inducing factors of urticaria all year round. Older children and adolescents begin to be allergic to drugs, especially penicillin, causing urticaria.
Children's urticaria is induced by drugs, cold, scorching sun and mental stress, and the urticaria accompanied by systemic diseases is far less than that of adults.
From the course of disease, children's urticaria mostly occurs in acute urticaria, but with the increase of age, children and adolescents' allergic eczema and asthma get worse, or urticaria caused by taking drugs (such as penicillins and sulfonamides) can gradually change from acute urticaria to chronic urticaria, while adults have more chronic urticaria and drug-induced urticaria than children.
2. Cholinergic urticaria
Most of them occur in youth, and appear after encountering heat (hot drinks, hot baths), emotional excitement and exercise. The rash is characterized by a small wind mass of 1~3 mm, with redness around it, mostly at the proximal end of trunk and limbs, fatigue and itching. Some patients have digestive tract symptoms, such as abdominal pain and diarrhea.
3, chronic urticaria
It is a disease for which the cause cannot be found. Patients often have a red, swollen and itchy rash on their body, face or limbs from time to time. The more they scratch, the more itchy they are, and the more swollen they scratch. The number of attacks varies from several times a day to once a few days.
4, cold urticaria
Acquired cold urticaria: it is the most common physical urticaria, which can be seen in the sudden onset of any age. After skin contact with cold air, cold water, etc. Itchy edema and wheal appear locally within a few minutes, which can last for 30~60 minutes and be relieved after heat preservation.
Hereditary cold urticaria: it is dominant inheritance and is more common in women. Infantile onset, lasting for life. A few hours after a cold, the whole body wind mass appears, which has a burning feeling and does not itch, and can last for 48 hours. At the same time, it is accompanied by chills, fever, headache, joint pain and increased cells.
5, papular urticaria
Papular urticaria is a common pruritic skin disease in infants. Lesions are usually round or spindle-shaped rash-like lesions with needle-like to bean-like blisters at the top, which are scattered or clustered. Common in limbs, trunk and buttocks. Generally, after a few days to 1 week, the lesion can subside on its own, leaving a temporary stain. Skin lesions can often appear in batches over a period of time. This disease has severe itching, and repeated scratching can cause pyoderma.
The cause of this disease is complicated, and most of them are related to insect bites, such as fleas, lice, mites, midges, bedbugs and mosquitoes.
6. acute urticaria
Acute urticaria is a localized edema reaction caused by various reasons, such as the expansion of small blood vessels in skin and mucosa and the increase of permeability. In urticaria, the whole skin inflammatory system is activated. Therefore, in the pathogenesis of acute urticaria, besides histamine, other transmitters also play a synergistic role.
Acute eczema, with rapid onset and polymorphic rash. The main manifestations are erythema, papules, papules, blisters, erosion, exudation and scab on the basis of edema, and the damage boundary is unclear. In severe cases, it can spread to the whole body with severe itching.
Subacute eczema, after acute inflammation is relieved, the rash is mainly small papules, scales and scabs, with only a few papules, blisters and erosion; Skin lesions are limited, and itching is still serious.
Chronic eczema is transformed from repeated attacks of acute eczema and subacute eczema. It is characterized by rough skin, scratches, scabbing, soaking hypertrophy, some lichenoid degeneration and pigmentation, and acne can be scattered around.
Scrotal eczema refers to a common skin disease confined to scrotum, and its etiology is complex, which may often be related to local uncleanness, tight underwear or airtight (chemical fiber products), allergies, some physical and chemical stimuli, or mental factors. The most prominent manifestations of the disease are local itching of scrotum, scratches left by local factors, slight erosion or infiltration of skin, and deep and wide skin wrinkles. Scratching due to strange itching leads to more scratching and a longer course of disease, which can affect sleep and work.
7. Peptone urticaria: (acute peptone allergic urticaria)
Under normal circumstances, peptone decomposed by protein in food is easy to digest, and is not or rarely inhaled into blood. However, when you eat too much (pork and seafood) at one time, and you are in high spirits and drink a lot, peptone can be absorbed into the blood through the intestinal mucosa and cause diseases, leading to congestion, redness and wheezing of the skin, accompanied by headache and fatigue. The course of the disease is very short, lasting only 1~2 days, and most of them can disappear within 1~4 hours. It belongs to antigen-antibody reaction, and its pathogenic medium is histamine.
8, solar urticaria:
The main manifestations are itching, erythema, wheal and vascular edema in the local area after the skin is exposed to the sun for several seconds to several minutes for 1~2 hours. Most of them are women.
9, skin scratches
Also known as artificial urticaria. After scratching or scratching the skin with a blunt instrument, a strip-shaped bulge appears along the scratch, accompanied by itching, which quickly disappears. Can occur alone or accompanied by urticaria. Can occur at any age. The disease often has no obvious cause, or it may be caused by drugs (especially penicillin).
10, serum urticaria:
Caused by drugs (penicillin, furazolidone, etc.). ), vaccine or allogeneic blood. Wind masses, especially polycyclic wind masses, are the most common skin lesions, and toxic erythema and erythema nodosum can also be seen. Patients also have symptoms of serum sickness or serum sickness-like reactions, such as fever, joint pain and lymphadenopathy. It can still damage the heart and kidneys. This is an antigen-antibody complex reaction.
1 1, compressive urticaria:
The skin appears after 4~6 hours of intense and lasting compression, and diffuse water swelling spots with unclear boundaries appear at the compression site, involving skin and skin tissue. It usually occurs in palms, soles and buttocks, and generally lasts for 8~ 12 hours. Sometimes it is accompanied by chills, headaches, joint pains and general malaise. The pathogenesis is related to kinin.
