51 Etiology (Diphylobotrium latum)
Zoonosis. Peroral biohelminthiasis
The source of the infection and definitive host is human. Intermediate host is a copepod (crustacean) The ancillary host is a fresh water fish Infection of the human is realized only in the use into the food of the thermic insufficiency cooking fish
Mechanic influence Attachment to the intestinal wall → attachment by bot to mucous membrane → athrophy and necrotization of the mucous membrane Toxicoellergic influence Sensibilization by products of the metabolism of helminth → endogenic hypo- and avitaminosis B 12
Clinical manifestations
weakness
dizziness
signs of the damage of the gastrointestinal tract
occlusive obstruction ileus
anemia
pallor
glossitis
loss of tonque papillae
achilia Compilations
anemia
obstruction of the intestine (till perforation)
finding of the helminth’s eggs in the feci Diagnostics
hyperchromic anemia
revealation of the eggs and proglotids of D.latum Treatment Etiotropic therapy Pathogenetic therapy
fenasal
Filicis maris acterium
praziquantel
vermox
treatment of anemia Prophylaxis
treatment of the patients
the quarding of the water reservoirs from the pollution by feci
fish tapeworm infection is prevented by throught cooking of freshwater fish
ECHINOCOCCOSIS 52 Etiology Echinococus granulosus
Zoonosis. Peroral biohelmintisis.
There are 2 types of the foci: 1. The natural foci (wild animals: beers, elks, wolfs, foxes) 2. Synantropic foci (sheeps, goats, dogs) The definitive host is dog.
duodenum → oncosphere → V.portae → liver (or brain, heart, kidney) → formation of the hydatid cyst in the site of the penetration ↓ ↓ Toxico-allergic action of the metabolic products of Echinococcus ↓ The local damage
the disorders of trophics
necroses, granulation
replacement of the perished by connective tissue Clinical manifestations
weakness, fatique
headache
increase of the temperature
dyspeptic manifestations
skin rash, itch Location of hydatid cysts: Liver (usually in the right lobe)
jaundice (cholestasis)
pain in the right part of the chest
pain in the right subribal area
on palpation – immovable compact formation Lungs
dyspnea
pain in the chests
cough Brain
clinics of the tumor Complications The rupture of hydatid cyst → anaphylactic shock 53 The cyst may rupture: 1.
obstruction through the capsule of the liver → into the peritoneal cavity → dissemination of scolices → formation of daughter cysts
an acute inflammatory reactions (peritonitis, meningitis, pleurisy)
in prolonged invasion → amyloidosis of the parenchymatous organs echinococcosis of the liver There are 3 stages
cirrosis of the liver
portal hypertension echinococcosis of the lungs → massive hemorrhage echinococcosis of the brain → epileptic attacks, loss of the vision, pareses, paralyses echinococcosis of the ovaries → rupture of the salpinx → hemorrhage Diagnostics
leukocytosis
anemia
accelerated ESR
eosinophylia
roentgenograms
USD
computed tomography
serological reactions (complement fixation, hemagglutination and other)
Treatment
the leading method of the treatment is surgical Prophylaxis
roles of the personal hygiene
helminthological investigation and dehelminthization of the dogs
