AIMS To evaluate an antigen capture enzyme linked immunosorbent assay (ELISA) which detects a carbohydrate epitope on the excretory-secretory (ES) antigens of Toxocara canis in clinical practice. METHODS Serum specimens from healthy adults, patients with acute visceral larva migrans, ocular and inactive toxocariasis, and with other helminth infections were examined by two site antigen capture...

A 54-year-old man with diabetes mellitus had a blood test and was found to have a blood eosinophilia (1,028/mm 3 ). Liverfunction tests were normal. A hepatic nodule was detected on screening of upper abdominal and renal sonography. Contrastenhanced computed tomography (CT) scan ( Figure 1 ) showed a small, oval, low-attenuating nodule in the right hepatic lobe. CT scans obtained 3, 6, and 10 m...

OBJECTIVES To present a detailed investigation of risk factors, symptoms, and laboratory and imaging tests that may be useful to establish the clinical laboratory diagnosis of visceral larva migrans (VLM) in children, demonstrating the importance of diagnosis and treatment to prevent complications in the eyes, liver, and other organs. SOURCES Literature review using the MEDLINE and LILACS (19...

For some time a syndrome of massive eosino-philia associated with respiratory and other symptoms has been recognized. The condition carries on the whole a good prognosis, is self-limiting and is most commonly seen in children, often occurring in several members of the same family. Frequently observed in the tropics or the subtropics, it has been variously described as Loeffler's syndrome, tropi...

A 16-year-old girl developed a cough, hypereosinophilia (absolute eosinophil count: 32000/mm3), hypergammaglobulinemia, and multiple noncavitary pulmonary nodules 1 month after having ingested an earthworm on a dare. Spirometry revealed moderate restriction and reduced gas diffusion. Parabronchial biopsy demonstrated eosinophilic organizing pneumonitis with multiple eosinophilic microabscesses,...

Soil contamination by embryonic eggs of Toxocara canis is the main source of human infection by this ascarid larvae resulting, sometimes, in the occurrence of visceral larva migrans syndrome. The objective of the present research is to determine the frequency of T. canis eggs in soil samples monthly collected in nine public places, located at the South Region of São Paulo municipality in a 18-m...

Toxocara canis, the common roundworm in the dog, can cause "visceral larva migrans" syndrome in humans, which may include generalised illness, eosinophilia, and symptoms arising from larval invasion of different organs. Of these, the clinically most important are liver, lungs, eyes and CNS. Involvement of the different parts of the CNS in human toxocaral disease has been described, but not the ...

We report four cases of passage of subadult or adult Toxocara cati worms by young children ages 20 months to seven years. Worms were expelled rectally in two cases and in two cases they were vomited. A single worm was passed in two cases, three worms in one case, and 15 worms in the fourth case. All worms that were available for study were identified as T. cati by morphologic criteria, includin...
