Helminthiases / / April 29, 2016
Heterophyosis (Lat.), Heterophyes (Eng.), Heterophase (fr.)
Helminthiases, the clinic which is dominated by intestinal disorders, but sometimes there are severe complications of the central nervous system and other organs.It occurs in Egypt, Greece, India and the Far East countries.
Etiology Pathogen - fluke Heterophyes heterophyes.Elongated body helminth dotted scales.Its length is 0.4-4 mm, width - 0.2-0.9 mm.In addition to oral and abdominal suckers, worms has a third, so-called sexual sucker, in the depths of which are sex hole.Eggs 0,028-0,030H0,015-0,017 mm in size, with a lid on one bulge and at the other end of the shell.
final home - a man, a dog, cat, fox, whose parasitic worms in the small intestine.Intermediate hosts - freshwater.For owners of fish - mullet (striped mullet) and mosquito fish.
geterofiesa Eggs, released into the environment in the faeces of humans and other definitive hosts contain larvae - miracidia.Miracidia hatch from eggs only at the last ingested mo
teterofiozom human infection occurs when eating raw, salted or insufficiently cooked fish.
Pathological anatomy and pathogenesis
geterofiesov a result of parasitism occurs in the small intestine catarrh of the mucous membrane, sometimes superficial necrosis her.A case of bleeding in the brain caused by the drift in his helminth eggs.Eggs geterofiesa found under the skin, the muscles, in the thickness of the intestinal wall, lymph nodes, heart valves, myocardium.
The pathogenesis is sensitizing the patient's organism, mechanical action on it of parasites and their eggs.
When geterofioze decreased appetite, pain in the upper abdomen, diarrhea alternating with constipation.The chair sometimes admixture of mucus.With the penetration of worms in the brain or in the brain drift of eggs having seizures, and even fatal bleeding.Defeat muscles and heart valves may result in the development of heart failure.
diagnosis is based ondetection of helminth eggs in feces.Keep in mind that these eggs are very similar with eggs and klonorhisa metagonimusa, so in case of doubt, have to resort to trial deworming.
Treatment and prognosis In
drift of eggs of the parasite in the heart and the brain may be a poor prognosis.When focal brain lesions may successful surgical treatment - removal of parasitic cysts.
Prevention do not recommend eating raw fish and half-baked.Social prevention is carried out by the protection of water from fecal contamination.
