How is intercalation schistosomiasis treated?

summary

Most patients have no obvious symptoms after infection. Severe infection may cause sudden pain in the left iliac bone. Because the female laid eggs in the mesenteric venules of the host, the host reaction caused by this insect was mild, and the liver biopsy showed the formation of eosinophilic abscess around the eggs. Colonoscopy showed congestion of mucosa near the rectal flap, inflammation of intestinal wall or polyp formation. The patient may have obvious gastrointestinal symptoms, blood and mucus in the stool, diarrhea, etc. Let's share my experience with you.

How is intercalation schistosomiasis treated?

In general, the first choice is neridazole, and the dosage and adverse reactions are as follows. Recently, it has been reported that praziquantel is effective. Control the source of infection, carry out general survey in epidemic areas, and carry out large-scale synchronous treatment for patients and sick cattle. The application of praziquantel to expand chemotherapy to control the epidemic of schistosomiasis can greatly reduce the number of patients, which is an important part of the whole prevention and control work, especially in the lake and mountain areas after three consecutive years. 5 ~ 2 mg / kg body weight, once intravenous injection has good curative effect.

In order to provide the basis for snail control planning, we should first find out the snail situation before cutting off the transmission route. In water network area, physical molluscicidal measures such as soil burying can be adopted to change the breeding environment of Oncomelania hupensis. The methods of damming, reclamation and planting can be used in Lake and marsh areas. Snail prevention belt should be set up around the residential area. Chemical molluscicide can be combined with physical molluscicide, such as niclosamide, and can be made into slow-release agent to prolong the molluscicidal effect. However, most molluscicides are harmless to crops, human and livestock, but toxic to fish, so the water pollution should be prevented.

Fecal management: prevent human feces and livestock feces from polluting water source, and make them harmless after treatment. If the mixture of feces and urine is 1:5, sealed, precipitated and fermented, and stored for 3-5 days in summer and 7-10 days in winter, schistosome eggs can be killed. In addition, the use of biogas cesspool in rural areas should be vigorously promoted.

matters needing attention

The key lies in publicity and education. We should guide people to pay attention to self-protection and try to avoid contact with infected water in epidemic areas. For example, children are forbidden to play in rivers and ditches. When harvesting, fishing, and threshing grass in Lake and marsh areas have to come into contact with epidemic water, personal protective measures should be taken. Fatty acid is used as the substrate, alkali saponification is added, and niclosamide (2%) and turpentine are mixed to make protective agent, which can kill cercariae. 1% niclosamide alkaline solution can also prevent cercariae.
