Teniasis - bot (cestodosis), parasitic disease, occurring with toxic-allergic reaction and dyspeptic disorders (disorder pischevarieniya).
Pathogen - tapeworm (cestode) Taenia solium (pork tapeworm, armed tapeworm)
The length of an adult - 1.5-2m and more. The head of the parasite has 4 suction cups and 2 rows of hooks (30). The life cycle takes place with the change of two owners - the human and pig. Helminths lives in the small intestine of man for a few years. Mature segments and eggs excreted with the feces into the environment, which are eaten by pigs (intermediate host). Externally, the eggs are indistinguishable from the bovine tapeworm eggs. In the intestine, porcine embryos from eggs out (hexacanth), penetrate into blood vessels and entered into the tissue where in 2-2.5 months in the muscles develop bubbles larvae (Finns or cysticerci) that resemble the Finns bovine tapeworm.
The disease recorded in Asia, Russia,Eastern Europe and Latin America. The final host and the source of infection - people. Intermediate hosts - pigs, rarely - pigs, dogs, cats, and people, in the intramuscular connective tissue which forms cysticerci 7-10 mm long. When ingested eggs from human tissue develops an infection - cysticercosis (a disease that is caused by parasitism in the body pork tapeworm larvae). By drinking contaminated pork taeniasis in humans develops (a disease caused by parasitizing more than 40 species of large cestode genus tenia).
How is teniasis
soft tissue cysticercosis often asymptomatic. In subcutaneous parasite watch soft single or multiple nodes (often on the chest and back). After the death of the parasites they are condensed and become painful. The most dangerous brain cysticercosis forming Finns 5-15 mm in diameter (in brain ventricles - up to 30-50 mm) compressing brain tissue. Depending on the localization of brain cysticerci may
headaches, epileptiform seizures (a commonname paroxysmal disorders (seizures), which is one of the manifestations of an organic process in the brain), delirium (delirium), hallucinations,
amential syndrome (a form of stupefaction, in which the predominant confusion, incoherence of thought and speech, chaotic movements), Hypertensive syndrome.
- Detection of eggs in faeces and hexacanth. At negative results apply bowel lavage
- Blood tests: eosinophilia (an increase in the number of eosinophils in the blood)
- A biopsy of the affected material
- cerebral cysticercosis
- Radiography; magnetic resonance imaging, computed tomography
- CSF (study of cerebrospinal fluid): lymphocytosis (increased number of lymphocytes) and eosinophilia (increased number of eosinophils); Lange test (characteristic curve resembles the curve in progressive paralysis).
Treatment and prevention teniasis
The drug of choice - phenasal 2 g (carefullycrush in 1/4 cup warm water) once in the morning on an empty stomach or at night 3-4 hours after a light dinner. 10-15 minutes before taking the drug give 1-2 g of sodium bicarbonate. An alternative drug is praziquantel, 2.5-10 mg / kg orally once.
When cysticercosis: surgical treatment (removal of large units) in combination with anti-inflammatory and dehydration therapy.
- Early identification of patients and monitor them for 6 months after treatment.
- Sanitary examination of pork.
