Human toxocariasis is a widespread parasitic disease caused by ingestion of Toxocara canis or catis larvae or eggs. Parasitic diseases are uncommon in industrialized countries, yet this problem has not disappeared. Parasitic diseases can cause different syndrome (visceral larva migrans, ocular larva migrans) and the clinical features can be confusing. Severe organ involvement affecting the live...

Toxocariasis is a parasitic infection caused by the roundworms Toxocara canis or Toxocara cati, mostly due to accidental ingestion of embryonated eggs. Clinical manifestations vary and are classified as visceral larva migrans or ocular larva migrans according to the organs affected. Central nervous system involvement is an unusual complication. Here, we report a case of multiple cerebral infarc...

Area and Costa Rica in general, free-ranging dogs are common , including at playgrounds and school yards, sites also vulnerable to nocturnal visits by raccoons. Dogs can have patent B. procyonis parasite infections and can play a role in transmission of the parasite from raccoons to humans. In Costa Rica, cases of larva migrans have been reported. The Unidad de Investigación y Análisis, Regis-t...

The raccoon roundworm, Baylisascaris procyonis, is increasingly recognized as a cause of serious or fatal larva migrans disease in humans and animals. We assessed the potential for infection in three northern California communities by determining the density and distribution of raccoon latrines, where transmission primarily occurs, and the prevalence of eggs at private residences. We collected ...

A 53-year-old woman developed an intensely pruritic rash on the plantar aspect of her right foot within 1 week of returning from a vacation in Jamaica, where she had walked barefoot on the beach (Fig. 1). The pattern revealed a classic serpiginous, elevated, erythematous lesion consistent with cutaneous larva migrans (CLM). CLM is the most common travel-associated dermatological infection prese...

Cutaneous larva migrans caused by the larvae of animal hookworms is the most frequent skin disease among travelers returning from tropical countries. Complications (impetigo and allergic reactions), together with the intense pruritus and the significant duration of the disease, make treatment mandatory. Freezing the leading edge of the skin track rarely works. Topical treatment of the affected ...

Cutaneous larva migrans (CLM) is a pruritic dermatitis caused by migration of the animal hookworm larvae into the epidermis. We present a case of CLM in a 31-year-old pregnant woman. The treatment of CLM relies on antihelminthic agents, such as thiabendazole, albendazole, and ivermectin. This case was interesting in that the standard treatment options previously mentioned were contraindicated o...
