[Visceral larva migrans in childhood: report of 2 cases]
Abstract:
Reports of Visceral larva migrans (VLM) are not frequent in Brazil, but the prevalence of this disease may be more common due to poor environmental conditions to which most of the children are exposed. The most common infectious agent is Toxocara canis, a parasite of the intestinal tract of dogs. Children get infected eating contaminated material with feces of dogs. The ova are swallowed and reach the intestinal lumen of the children. Systemic migration occurs by lymphatic or portal circulation to several organs, most frequently, to the liver and lungs, causing hepatosplenomegaly and/or bronchospasm.
Insights
Visceral larva migrans (VLM), often caused by Toxocara canis, may be more prevalent in Brazil due to poor sanitation. Infection occurs when children ingest contaminated dog feces, leading to larva migration to organs like the liver and lungs.
Area of Science:
- * Parasitology
- * Pediatrics
- * Public Health
Background:
- * Visceral larva migrans (VLM) is a human parasitic infection.
- * Toxocara canis, a common dog intestinal parasite, is the primary etiological agent.
- * Poor environmental conditions in Brazil may increase VLM prevalence.
Observation:
- * Children are particularly vulnerable due to exposure to contaminated environments.
- * Infection occurs through ingestion of parasite ova present in dog feces.
- * Larvae migrate systemically after ingestion.
Findings:
- * Migrating larvae commonly reach the liver and lungs.
- * Clinical manifestations include hepatosplenomegaly and bronchospasm.
- * VLM is reportedly infrequent in Brazil, but underdiagnosis is possible.
Implications:
- * Highlights the need for increased awareness and diagnosis of VLM in Brazil.
- * Emphasizes the importance of public health interventions and improved sanitation.
- * Suggests potential for higher prevalence than currently reported, necessitating further investigation.
