rash
Introduction
Introduction to rash Creepingeruption, also known as mobile larvae (migrans), is more common in the tropics. It is not uncommon in Southeast Asia. It has also been reported in southeastern China. When eggs in the feces hatch into infectious larvae, when the human body, especially children, are exposed to larvae When it is drilled into the skin, it develops symptoms. The larvae appear symptoms within a few hours after invading the skin. The larvae begin to consciously itch on the skin, also on the leather surface, and also have a cord-like shape, and the cat hookworm is found in the lesion. , dog hookworm, pig's jawworm, horsefly, horsefly, etc., can be diagnosed. basic knowledge The proportion of illness: 0.004%-0.008% Susceptible people: insect vector transmission Mode of infection: non-infectious Complications: herpes zoster
Cause
The cause of rash
(1) Causes of the disease
It is caused by the infestation of the mites of the Brazilian hookworm (cat hookworm), the dog hookworm and the parasitic cat, the pig's jawworm, the horsefly, the horsefly, etc. when the human body comes into contact with the cat containing the mites. The soil contaminated by the feces excrement of the dog, or the uncooked meat containing the aphid, can cause the disease. This kind of aphid is parasitic on the epidermis or subcutaneous tissue of the skin, so the skin lesions are many. See, occasionally invade the lungs and their internal organs, the mites of the larvae can still be parasitic in some freshwater fish and frogs, squid and other bodies, such as eating these uncooked fish can also cause disease.
(two) pathogenesis
When the human body comes into contact with cats containing such aphids, soil contaminated by feces excrement, or uncooked meat containing such aphids, eat these uncooked fish, frogs, squids , can cause the disease, such aphids are more parasitic under the skin epidermis or subcutaneous tissue, so skin lesions are more common, occasionally invade the lungs and their internal organs, larvae migrate in the lungs, causing the body to a kind of worms Allergic reaction.
Prevention
Rash prevention
1. Strengthen publicity and education on health, avoid contact with soil contaminated by cat and dog excrement, and avoid walking barefoot in the mud.
2. Children should not directly contact animals such as dogs and cats. Improve and pay attention to personal hygiene. Children should not suck their fingers and wash their hands before and after meals.
Complication
Herpes rash Complications herpes zoster
It can be complicated by Loeffer syndrome, temporary lung, migratory infiltration, blood eosinophils can be as high as 51%, and sputum can reach 90%.
Symptom
Herpes rash symptoms common symptoms purulent knot itching
Under certain environmental conditions, the eggs develop into the third stage larvae and begin to infect the human body. Symptoms appear within a few hours after the larva invades the skin. The larvae move in the skin and begin to consciously itch. There are also hard and small lumps. The aphids move under the skin, and the skin has a reddish, tortuous, linear lesion. The micro-bumps rise from the leather surface, and there are also strips. The length is variable. Generally, the aphids move about a few centimeters a day, and the lesions continue to advance. Can be as long as 15 ~ 20cm, the old damage can tend to subside, the mites move through, can also be temporarily still for several days or even months, sometimes the mites often move with the nails, can be secondary to infection, suppuration, conscious interval Stinging or itching, which occurs mostly in the exposed area, can also be seen in the buttocks and vulva.
Examine
Check for rash
Laboratory inspection
Blood eosinophils usually increase, and transient infiltration of the lungs can be revealed by X-ray examination of the lungs.
Other auxiliary inspection
Pathology: Animal larvae can not adapt to the human body, generally can not mature in the human body, and stay in the larval stage. Therefore, no adult or insect eggs are visible in the human body; at the same time, the larva can not reach its normal parasitic parts, but in the migration Atopic lesions are produced in the tissues and organs that pass through.
The larvae usually burrow in the granules or spines in the skin. In the skin near the tunnel, there are round cells and eosinophils infiltrating around the blood vessels. The worms are slightly deeper in the skin, but the inflammatory response is basically the same.
Diagnosis
Diagnosis of rash
diagnosis
The skin has a reddish, tortuous, linear lesion. The micro-bump is on the leather surface. It is also in the form of a strip. The length is variable. Generally, the aphid moves about a few centimeters a day, and the lesion continues to advance, which can be as long as 15 to 20 cm. Old damage can tend to subside. The locusts move through and can remain static for days or even months. Eat these uncooked fish, frogs, squid, cats that contain such mites, and dog feces. Etc., find the cat worms, dog hookworms, pig larvae, horse flies, horse worms and other aphids in the skin lesions, you can confirm the diagnosis.
Differential diagnosis
The rash should be differentiated from hemorrhoids, schistosomiasis, filariasis, schistosomiasis, and dermatitis.
