Etiology Enterobius vermicularis Epidemiology Anthroponosis. Peroral contageous helminthiasis.
The mechanism of the transmission is fecal-oral
The infection is realized in oral cavity
The maturation of the invasive eggs with larvae is finished in 4-6 hours on the skin of the human.
Larvae in the distal section of the small intestine → rectum (female) → eggs on the perianal area and perineum The mechanic lesion of the mucous membrane → inflammatory changes, hemorrhages
itch
pyodermia
headache
disorder of sleep
irritation
dizziness Compilations
appendicitis
perforation with peritonitis
Treatment Etiotropic – mebendazole (treatment is effective only in observance of the rules of the personal hygiene)
dehelmintization of the patients
sanitary-hygienic measures in the foci chemioprophylaxis is performed
42 TRICHOCEPHALOSIS Etiology Trichocephalus trichiuris Epidemiology Anthroponosis. Peroral biochelminthiasis
The mechanism of transmission is fecal-oral The factors of transmission are vegetables, fuits, water The infection of the human is realized in use with the food only matured eggs
membrane of the small intestine → the large intestine ↓ ↓ Traumatization of the wall of the large intestine → admixture of the bacterial flora → inflammatory reaction → formation of the infiltrates (typhlitis) Penetration into the mucous and submucous layers → constant irritation of the interoreceptors → disorders of the function of the stomach, duodenum and central nervous system
Clinical manifestations ↓ ↓
diarrhea
hemocolitis
tenesmus
pain in the right hypogastrium
hypochromic anemia
dizziness
decrease of artherial pressure tachycardia Compilations
rectal prolapse
appendicitis
hypochromic anemia Diagnostics
eosinophilia
hypochromic anemia
finding of the eggs of helminths in feci Treatment
albendazolum
mebendazolum Prophylaxis
detection and treatment of the patient
sanitary-hygienic measures
washing of vegetables and fruits 43 ANCYLOSTOMIDOSES (ANCYLOSTOMOSIS AND NECATOROSIS) Etiology Ancylostoma duodenale / Necator americanus Epidemiology Anthroponosis. Percutaneous and peroral heohelminthiases Main route of transmission - percutaneous The susceptibility is general Pathogenesis Early (migratory) phase Late (intestinal) phase ↓ ↓
allergic reaction
perivascular infiltration of the lungs
Fixation of ancylostoma to mucous membrane of the small intestine (hypoalbuminemia)
itch, urticar rash, increase the temperature, cough with asthmatic component (sputum with blood)
nausea
vomiting
pain in the epigastrium
diarrhea
anemia is leading symptom (in 3-6 month)
pain in the muscles
dry skin
edema of the low extremeties Compilations
infection of the skin in the area of the entrance gate → sepsis, tetanus, erythypilas, carbuncule
Quinke’s edema, laryngospasm
hypochromic anemia Diagnostics General methods
leukocytosis
eosinophilia
increase the ESR
hypochromic anemia Biochemical methods
general of serum Fe Specific methods: finding of the eggs of helminths in the feci Treatment Etiotropic therapy: albendazole, levamizole, mebendazole, thiabendazole
sanitary-hygienic measures devastation of soil
Pathogenetic therapy: treatment of anemia and hypoalbuminemia, desensibilization
