Anisakiasis Migrans
Introduction
Introduction to Heterosis Anisakismanina is a visceral helminthism caused by infected larvae such as marine fish and mollusks such as squid. It is often characterized by acute abdomen in the early stage of infection. Chronic recurrent epigastric analgesia, gastrointestinal or extraintestinal eosinophilic granuloma formation. Once the worms pass through the digestive tract stomach, the intestinal wall enters the abdominal cavity and migrates to the liver, kidney, pancreas, lung, ovary, mesentery, etc., causing severe cellulitis, eosinophilic abscess and granuloma of various organs, becoming ectopic Anisakisis, the throat and oral mucosa can also be involved. basic knowledge The proportion of illness: 0.0005% Susceptible people: no specific population Mode of infection: digestive tract spread Complications: Cellulitis Acute diffuse peritonitis
Cause
Etiology of ecliptic mites
The adult worms are parasitic on the stomach of marine mammals such as whales, dolphins, seals, etc. The eggs are discharged into the seawater with feces and hatch larvae. The larvae are swallowed by crustaceans such as scale shrimp and further develop into infection period. Larvae, after being swallowed by sea fish such as crickets, crickets, squid and Japanese scorpionfish, squid, squid, squid, etc., the infected larvae live in their muscles or abdominal cavity, and after being preyed by whales, the larvae penetrate into their stomach wall. Continue to develop into adults.
Prevention
Hemiplethus mites migration prevention
In the medical history, you should inquire about the history of medication, food history and other allergies. The absolute value of eosinophils in the surrounding blood exceeds 3.0 × 109 / L to support the diagnosis of this disease. Blood IgE is measured at a high level. If it is suspected that the disease is caused by the migration of dogs and cats in the body, an enzyme-linked immunosorbent assay (ELISA) can be performed to detect antibodies against canines and meerkats, and to infect human aphids. Identification. Secondly, the fish should be cooked and then eaten; the fish must be frozen at -20 °C for 24 hours before entering the market.
Complication
Heterosis of the parasitic worm Complications Cellulitis Acute diffuse peritonitis
Once the insects pass through the digestive tract stomach and intestinal wall into the abdominal cavity, they move to the liver, kidney, pancreas, lung, ovary, mesentery, etc., causing the spread of infection, leading to severe cellulitis, eosinophilic abscess and granulation of various organs. Swollen, become ectopic nematode disease, throat and oral mucosa can also be involved, larvae can cause diffuse peritonitis, intestinal mucosal ulceration, and even intestinal perforation.
Symptom
Symptoms of Shigella sinensis, common symptoms, peritonitis, abscess, granuloma
The eclipse of the sea larvae and squid, which are infected with larvae in the life or the half-life, is in the stomach and small intestine wall of the human body. The latter is especially common in the ileum; once the worm passes through the digestive tract stomach, the intestinal wall Enter the abdominal cavity, and move to the liver, kidney, pancreas, lung, ovary, mesentery, etc., resulting in severe cellulitis, eosinophilic abscess and granuloma of various organs, becoming ectopic nematode disease, throat and oral mucosa Involved.
According to epidemiological data, there are raw fish and other fish history. Typical clinical symptoms are the main basis for diagnosis. Gastroscope can detect esophageal or gastric larvae can be diagnosed, ectopic lesions are difficult to diagnose, latex agglutination test, enzyme-linked immunosorbent assay can assist diagnosis .
Examine
Examination of the migration of echinococcosis
1. Peripheral blood test:
Eosinophils in the surrounding blood are larger than normal, and contain large particles, the number of cells increases, accounting for 20% to 70% of the total number of white blood cells, and the direct count of eosinophils is usually around 3.0×109/L.
2. Immunological examination:
The parasite antibody test in the blood can be positive; the IgE can be as high as 2300 ng/ml, and those with hepatomegaly often show hyperglobulinemia.
3. Parasitic egg inspection:
Alveolar lavage fluid and 24h parasite eggs can be found positive.
4. Skin test:
The skin test of the parasite skin test can be positive.
5. Gastroscope:
Can detect the esophagus or stomach larvae can be diagnosed. Difficulties in the diagnosis of ectopic lesions, latex agglutination test, enzyme-linked immunosorbent assay can assist in diagnosis.
6. Other auxiliary inspections:
Chest X-ray films show cloud-like patchy patches, the scope of which is not specified, the shadows can disappear in a short period of time, and soon appear again, the parts can migrate without being constant. Sometimes the atelectasis can be shown.
Diagnosis
Diagnostic identification of migraine
The disease is mainly differentiated from visceral helminthism and sea worm. Secondly, it is necessary to distinguish from other infectious diseases with clinical manifestations similar to this disease, such as mesenteric lymphadenitis, cholecystitis, pancreatitis, appendicitis, intestinal obstruction, ulcerative colitis, all of which can cause echinococcosis Transient abdominal cramps, it should be clear according to the characteristics of pain, B-ultrasound, CT examination.
