Sparganosis
Introduction
Introduction to schizophrenia Sparganosis is a skin disease caused by the larvae of the larvae of the larvae of the genus Mantis, which is found in the muscles and subcutaneous tissues of animals such as frogs and snakes. The uncooked frog meat containing such mites Or the snake meat is eaten by humans, or the water contaminated by the genus Swordfish, which is infected with the schistosomiasis, or the external frog skin and frog meat infected with the mites are directly applied to treat skin ulcers or eye diseases, and the mites can directly pass through the skin wounds. Enter the subcutaneous tissue and cause the disease. Its development involves terminal hosts (such as dogs and pigs), two intermediate host crustaceans and vertebrates (such as reptiles, birds). Humans are temporary hosts for second-stage larvae. basic knowledge The proportion of illness: 0.005% Susceptible people: no special people Mode of infection: non-infectious Complications: iridocyclitis cataract
Cause
Cause of schizophrenia
Local application of raw frog meat, succulent or half-baked frog, snake meat or pork infection, swallowing live sputum to drink raw water or swimming and swallowing the scorpionfish containing the original scorpion to infect, the mites directly enter the skin through the skin wound Tissue causes disease.
Apply the frog to the affected area (30%):
This is the main form of infection. In Southeast Asia, especially in some parts of China and Vietnam, folklore frogs have a cooling and detoxifying effect. They often add whole frogs or visceral frogs to brown sugar and apply them to wounds, abscesses, eye diseases or To treat toothache, if there is a crack in the frog meat, it can invade the human tissue from the wound, normal skin and mucous membrane.
Swallow raw or undercooked meat (30%):
Chinese folks have the habit of swallowing live frogs to treat sores and pains; there are also practices for eating skin to treat skin diseases. In Yanbian area, residents like to eat half-baked frog or raw frog meat, snake meat and pigs, cattle, fish; Guangdong, Hong Kong and other places like to eat rice porridge (frog Guangdong called frog) or fried frog meat and snake meat, The above production method failed to kill the phlegm that is parasitic in the deep part of the muscle, and the human body is infected. A peasant in a certain place in Fujian swallowed 7 small frogs due to misdiagnosis of "sinus" by acne, and then removed the sputum from the leg after surgery.
Inadvertently infected Sword Shui (30%):
Drinking raw water or swimming, drinking water, drinking water, pond water, so that the infected sword scorpion has a chance to enter the human body, the original scorpion scorpion escapes from the body of the sword, through the intestinal wall into the abdominal cavity, visceral tissue or migrate to the muscles The subcutaneous tissue develops into a phlegm.
Pathogenesis
The frog meat or snake meat that has not been cooked is eaten by humans, or the water contaminated by the genus Swordfish, which is infected with the mites, or the raw frog skin infected with the mites, and the frog meat is directly applied to treat skin ulcers or eye diseases. It can cause disease by directly entering the subcutaneous tissue through the skin wound.
Prevention
Split rickets prevention
Avoid using raw frog skin, frog meat to treat skin diseases, not eating uncooked frog meat, snake meat, and not drinking raw water.
Complication
Ricket rickets complications Complications iridocyclitis cataract
1) ocular rickets are more common, mostly unilateral, patients with eyelid swelling, conjunctival congestion, slight pain, itching, photophobia, tearing or worm crawling, can be touched under red or swollen eyelids or under the conjunctiva A lump or cord-like substance with varying degrees of hardness and hardness. Such as the head mistletoe in the eyeball can make the eyeball prominent, and painful keratitis, iridocyclitis, vitreous opacity, cataract, corneal ulcer perforation and even blindness.
(2) The mouth of the oral cavity is swollen, itchy, itchy, and there is an induration in the submucosal mucosa.
(3) Subcutaneous cleft rickets in the trunk, limbs, vulva, etc. appear in the trunk, large to walnut large, round, oval, strip-like or irregular subcutaneous nodules or masses, the number is generally 1 to 2, the skin The noodles are elastic, the touch is sensation, the part is itchy, and it has the characteristics of migration. 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.
(4) visceral schizophrenia is rare in this type. Can be parasitic in the respiratory tract to cause hemoptysis. Parasitic gastrointestinal fistula can invade the peritoneum and cause an inflammatory reaction. Parasitic in the urethra, bladder can cause urinary inflammation. It can also parasitize the brain and can cause serious consequences.
Symptom
Symptoms of schizophrenia common symptoms subcutaneous finger to pigeon eggs... edema nodules itching eye can not move subcutaneous nodules
The skin lesions are inflammatory mass nodules from the finger to the lower torso of the trunk or lower limbs. The number is 1-2. The affected part has edema and itching, and it can also have no feeling. Parasitic on the eye can cause Painful conjunctivitis, or cause eye movement to limit and destroy the eye.
Examine
Examination of schizophrenia
1. Blood: Most white blood cell counts are normal, and eosinophils are slightly elevated.
2. Biopsy; worms can be found in subcutaneous masses and orbital nodule biopsies.
Pathological examination showed eosinophilic granuloma, and the center of the lesion was the transverse section of the worm.
Diagnosis
Diagnosis and identification of schizophrenia
The diagnosis is mainly based on the epidemiological history, subcutaneous nodules or mass and biopsy. Where the frog meat is applied to the wound, the scab and the eye are either raw frog, snake, pork history, clinical manifestations have subcutaneous walking Nodules and masses should consider this disease, biopsy can find the worm to confirm the diagnosis, and the intradermal test of the sputum sputum antigen has an auxiliary diagnostic value.
Differential diagnosis
The disease should be differentiated from cysticercosis, paragonimiasis (Pneumocystis sinensis), ocular rickets, especially after the ball infection caused by ocular protrusion should be differentiated from retinoblastoma.
Pmliferative sparganosis is a rare parasitic disease. There have been 8 cases diagnosed so far, including 5 cases reported in Japan, 1 case in the United States and 1 case in Venezuela. The pathogen is Sparganum proiferum, only found in People, may also be in the body of the black-tailed macaque, the worm body is columnar or slightly flat, often curled, with irregular branches and buds, about 10mm × 1mm in size, up to 24mm, can be transferred to various tissues in the body, Bud hyperplasia, tissue sections can be seen in the internal tissue with scattered bundle-like longitudinal muscles, there are many small vesicles and bubbles in the epidermis or under the skin, the drainage tube expands into a large cavity, and some of the worm body has a deep concave at one end, but no In the head section, the insect body can invade the subcutaneous, intermuscular fascia, intestinal wall, mesentery, kidney, lung, heart, brain and other tissues after invading the human body. The affected tissue is honeycomb and nodular, which can cause extensiveness in the limbs. Swelling, like skin swelling, patients are getting weaker, thin and prostration, and even leading to death. In addition, Taiwan and the Philippines reported 3 cases of "proliferative" schizophrenia, the pathogen being a fragmented sputum or four head lice. The worm body is small, the longest is no more than 2mm, the width is 0.1mm, the shape is irregular, spherical, columnar or worm-shaped, and some of the epidermis is folded into an irregular bag, and the saclike parenchyma is enlarged by the drainage tube. If the development is incomplete and mature, the matured ones can distinguish the mites, which can also invade the tissues of the lungs, chest, abdomen or lymph nodes, causing serious consequences. This schizophrenia is also seen in dogs in Taiwan and the United States. And cats, for the first time in China, a case of proliferative schizophrenia was found in Guangdong. It may be caused by a poorly differentiated Mang's schizophrenia. For example, after feeding a cat with a live worm, the eggs are found in the feces and adults are found in the small intestine. Can be identified.
