Subcutaneous sparganosis

Introduction to subcutaneous split rickets Subcutaneous schistosomiasis is a skin disease caused by the mites of the mites, which are found in the muscles and subcutaneous tissues of animals such as frogs and snakes. The uncooked frog or snake meat containing such mites is human. After eating, or drinking water contaminated by the genus Swordfish, which is infected with a mites, or directly applied to the skin ulcers by using the frog skin and frog meat infected with the mites, the mites can directly enter the subcutaneous tissue through the skin wounds and cause the disease. Man's schizophrenia is more common in East and Southeast Asian countries. China is more common in Guangdong, Jilin and Fujian. basic knowledge The proportion of illness: 0.001% Susceptible people: no special people Mode of transmission: spread by parasites Complications: headache, peritonitis, hemoptysis

Causes of subcutaneous split rickets

(1) Causes of the disease

The schistosomiasis is called the mites of the worms, and the adult worms are parasitic in the intestines of cats and dogs. The eggs are excreted in the feces and develop into the original scorpion, which is parasitic on the muscles of the frog. If the frog meat is applied to the eyes, wounds, and abscesses, the mites in the frog meat invade the human body due to the warming characteristics; eating unripe frogs, snakes, birds or pork, splitting the head and mouth, and finally moving to skin. Or a raw or half-baked frog, snake or pork, swallowing live cockroaches, drinking raw water or swimming, etc., swallowing the sword scorpion containing the original scorpion, the scorpion scorpion enters the body and then drills from the abdominal cavity and moves to the subcutaneous tissue. To. The mites have a long life and generally survive for 12 years in the human body.

(two) pathogenesis

The mites are parasitic on the small intestines of cats, dogs, tigers, leopards, foxes, etc. The eggs are excreted with the feces, and the snails are hatched in the water. After being swallowed by the first intermediate host, Jianshui, the cilia are removed in the body. It becomes the original scorpion, and the sword scorpion containing the original scorpion is swallowed by the second intermediate host, , into a mites. When the scorpion develops into a frog, the mites migrate to the frog's thigh and calf muscles, such as frogs and snakes. When predation, snakes and birds become the host of reproduction. If dogs, cats, etc. swallow the infected frogs and continue to host, the mites will parasitize in the final host such as dogs and cats and develop into adults. It is possible for a person to become a second intermediate host, a relay host or a terminal host.

There are more than one crack in the human body, but there are also 2-3, or even more than 10. The affected part can form an eosinophilic granuloma cyst, causing local swelling and even abscess. The secretions of the worms and the lysates after the excretion or death of the worms can cause eosinophilic granuloma and can be formed by cysts and tunnels. In the cystic cavity, there is a white bean dregs-like exudate, which consists of coagulated necrotic tissue, fibrin and a small amount of red blood cells, of which Xia Lai crystal can be seen. The wall of the capsule consists of granulation tissue. When the bud colony is in the subcutaneous tissue of the mistletoe, a subcutaneous mass is formed. In particular, the labia, breasts, eyelids, chest and abdomen are easy to develop, and there are moving masses like the size of eggs and pigeon eggs. The small lumps of surgical resection can be found in the small lumps.

Subcutaneous cleft palate prevention

Do not eat uncooked frogs, snake meat, etc., do not use frogs, snake meat, skin to apply eye or skin ulcers, do not swallow snakes, do not drink raw water. Do a good job in propaganda work in popular areas to let the masses understand the route of transmission of this disease, change bad eating habits, and crack rickets are completely preventable.

Subcutaneous rickets complications Complications, headache, peritonitis, hemoptysis

If there is inflammation, it may be accompanied by pain and tenderness. Sometimes there may be wheal. Some patients may not have any symptoms after infection. It can last for several years. Some rashes can resolve on their own, but relapse after a while. The mites can migrate through the body and invade a variety of tissues and organs. Oral and maxillofacial: often induration in the oral mucosa or under the skin of the face, the affected area is red, swollen, itchy or worm-like. Cerebral palsy: symptoms and signs of nervous system such as headache, vomiting, and convulsions. Some can invade the peritoneum through the digestive tract, causing peritonitis, or parasitic in various organs in the abdominal cavity. It can also move up, through the diaphragm into the chest, to the chest wall, breasts, neck; or into the lungs leading to chest pain, cough, hemoptysis. Also found in the spinal cord, spinal canal, urethra, vulva, genitourinary and bladder.

Symptoms of subcutaneous split rickets common symptoms nausea, photophobia, subcutaneous nodules, conjunctival congestion, itching, drooping, tears

Skin manifestations: Skin lesions are inflamed migratory mass nodules from the finger to the lower torso of the trunk or lower limbs, round, columnar or linear, medium hardness, no adhesion to the skin, no tenderness. It can affect the patient's limbs, chest and abdomen wall, breast and external genitalia. The number is 1 or 2, which may have itching and insect crawling. There is no feeling. If the infection is combined, symptoms such as redness, swelling, heat, and pain may occur, and urticaria sometimes occurs.

Eye skin infection: The patient presents with redness and swelling of the eyelids, drooping eyelids, conjunctival hyperemia, photophobia, slight pain, itching, foreign body sensation and insect crawling, which may be accompanied by nausea, vomiting, fever and other symptoms. Mostly single-eye infections can be repeated and unhealed for many years. It can cause painful conjunctivitis, or cause eye movement to limit and destroy the eyeball, which eventually leads to severe vision loss or even blindness.

Examination of subcutaneous split rickets

1, blood: white blood cell counts are mostly normal, eosinophils slightly increased.

2, biopsy: the eyelids and other parts of the skin downstream of the walking nodules, subcutaneous mass and orbital nodule biopsy can find the worm body.

3, pathological examination: showing eosinophilic granuloma, visible Xia Lai crystal. The center of the moving mass lesion is the transverse section of the worm.

4, using enzyme-linked immunosorbent assay, indirect fluorescent antibody test can assist diagnosis.

Diagnosis and diagnosis of subcutaneous split rickets

diagnosis

Mainly based on the epidemiological history, where the frog meat is applied to the wound, the sore and the eye, or the history of raw frogs, snakes, and pork, there is a history of splitting. Clinical manifestations of patients with subcutaneous salivary nodules and masses should consider this disease. From the lesion, the diagnosis of schizophrenia was the basis for diagnosis. The intradermal test of the sputum sputum antigen has an auxiliary diagnostic value.

Differential diagnosis

Pmliferative sparganosis is a rare parasitic disease. The pathogen is Sparganum proiferum, which is found only in humans and may also be found in black and long-tailed monkeys. The worm body is columnar or slightly flat, often curled, with irregular branches and buds, about 10mm × 1mm in size, up to 24mm in length, and can be transferred to various tissues in the body for bud proliferation. The tissue section shows that there are scattered bundle-like longitudinal muscles in the internal tissue, and there are many small capsules and bubbles in the epidermis or under the skin, and the drainage tube is expanded into a large cavity. Some worms have a deep concave at one end, but no head knuckles. After invading the human body, the insect body can invade various tissues such as subcutaneous, intermuscular fascia, intestinal wall, mesentery, kidney, lung, heart and brain. The affected tissue is honeycomb-like and nodular, and can cause extensive swelling in the limbs. It seems to be a skin swelling, and the patient is getting weaker, thinner and collapsed, and even leads to death.

Subcutaneous tissue and muscle cysticercosis: patients often have subcutaneous or intramuscular cystic nodules, distributed in the head and trunk, fewer limbs, nodules are round or elliptical, 0.5 to 1.5 cm in diameter, solid, can be subcutaneous or Free push in muscles, no tenderness. Nodules can appear one after another or disappear on their own. The skin manifestation of paragonimiasis: the main manifestation of the migratory subcutaneous mass. The size of the mass is different, the surface of the skin is normal, and the mass is touching. Often single scatter, even multiple strings are visible. After a mass disappears, it appears in the vicinity or elsewhere in some time. The often-developed parts are the abdominal wall, chest and back, head and neck, and the like. Almost everywhere on the surface of the human body, there is a possibility of a lump.
