toxocariasis

Visceral larva migrans Parasitology A disease primarily of children due to dog–Toxocara canis and cat–T cati parasites that inhabit the GI tract and release eggs in the feces; when children ingest eggs from contaminated plants, dirt, stool, eggs hatch into larvae in GI tract, burrow through the wall and migrate elsewhere, primarily to liver and lung, but also brain, eye, etc, causing inflammation and tissue damage in transit Clinical Fever, pulmonary complaints–eg, cough, wheezing, seizures, rash, ↓ visual acuity due to migration through ocular structures–periorbital edema, strabismus Prognosis Generally self-limited, Sx eventually disappear; there is no specific therapy

toxocariasis

Infection, via the mouth, with the juvenile forms of the common bow-shaped puppy worm Toxocara canis . This is a frequent event in children in contact with puppy fur and contaminated soil. Infection causes a transient illness with fever, lassitude, loss of appetite, pallor and often coughing and wheezing. Rarely, a juvenile worm may lodge in an eye and cause a tumour-like mass on the retina that may damage vision and may be mistaken for the highly malignant RETINOBLASTOMA. Puppies are often infected before birth and should be de-wormed regularly.

Chronic ocular toxocariasis is usually diagnosed based on clinical findings of granulomas in the retina or at the optic disc together with Toxocara seropositivity.
In a seroprevalence study of children toxocariasis carried out in Maracay, Venezuela [24], 50-60% of the children had contact or played with the dogs present in parks or near their schools, but there was no relationship between the keeping of dogs at home and seropositivity, so it is important to consider dog caretakers as the most prone group in acquiring the infection because of handling of feces.
In Bulgaria, toxocariasis is not a notifiable disease, but according to previous studies of patients with allergy and/or eosinophilia, its seroprevalence ranges between 12.25% and 14.01%, (15-18).
