Larvas de helmintos no solo de praças públicas de Caxias, Maranhão, Brasil / Helminth larvae in the soil of public squares in Caxias, Maranhão, Brazil / Larvas de helmintos en el suelo de plazas públicas en Caxias, Maranhão, Brasil

Solos de praças públicas são comumente contaminados por helmintos devido ao fácil acesso de cães e gatos infectados. Esses animais ao defecarem podem liberar ovos desses parasitos e, em condições ambientais favoráveis, tornam-se ovos embrionados ou larvas infectantes. O objetivo deste trabalho foi investigar a existência de larvas de helmintos no solo de duas praças públicas do município de Caxias, Maranhão, Brasil, durante a estação chuvosa e seca na região. A pesquisa foi realizada em março de 2018, considerado período chuvoso, e em outubro do mesmo ano, período seco, sendo que foram coletadas trinta amostras de areia, quinze de cada praça, nos dois períodos do ano. O material foi coletado e levado para o Laboratório de Parasitologia do Departamento de Parasitologia e Microbiologia da Universidade Federal do Piauí para análise. Na estação chuvosa, das quinze amostras analisadas na praça A, cinco foram positivas para larvas de ancilostomídeos e das quinze na praça B, três estavam contaminadas com os mesmos helmintos. No período seco, na praça A havia apenas uma amostra com essas larvas e na praça B não foram encontrados parasitos. Os resultados revelaram a presença de larvas de helmintos de caráter zoonótico no solo de praças públicas de Caxias, Maranhão, principalmente no período chuvoso, servindo de alerta à população local.(AU)

Soil in public squares is commonly contaminated by helminths due to the easy access of infected dogs and cats. These animals, when defecating, can release helminth eggs and, under favorable environmental conditions, those eggs can become embryonated or infective larvae. The purpose of this work was to investigate the existence of helminth larvae in the soil of two public squares in the city of Caxias, in the state of Maranhão, Brazil, during the rainy and dry seasons in the region. The study was carried out in March 2018, which is considered the rainy season, and in October of the same year, the dry season. A total of thirty sand samples were collected, fifteen from each square, in both periods of the year. The material was collected and taken to the Parasitology Laboratory of the Department of Parasitology and Microbiology of the Federal University of Piauí for analysis. In the rainy season, from the fifteen samples analyzed in square A, five were positive for hookworm larvae; and from the fifteen samples collected from square B, three were contaminated with the same helminths. During the dry period, only one sample from square A presented these larvae while no parasites were found in square B. The results revealed the presence of zoonotic helminth larvae in the soil of public squares in Caxias, Maranhão, mainly in the rainy season, which can be used as a warning sign to the local population.(AU)

Los suelos de las plazas públicas son comúnmente contaminados por helmintos debido al fácil acceso de perros y gatos infectados. Esos animales, al defecar, pueden liberar huevos de esos parásitos y, en condiciones ambientales favorables, convertirse en huevos embrionados o larvas infectantes. El objetivo de este trabajo fue investigar la existencia de larvas de helmintos en el suelo de dos plazas públicas de la ciudad de Caxias, Maranhão, Brasil, durante la estación lluviosa y seca de la región. La investigación se realizó en marzo de 2018, considerada época de lluvias, y en octubre del mismo año, época seca, y se recolectaron treinta muestras de arena, quince de cada plaza, en ambos períodos del año. El material fue recolectado y llevado al Laboratorio de Parasitología del Departamento de Parasitología y Microbiología de la Universidad Federal de Piauí para su análisis. En época de lluvias, de las quince muestras analizadas en la plaza A, cinco resultaron positivas a larvas de anquilostomiasis y de las quince de la plaza B, tres estaban contaminadas con los mismos helmintos. En el período poco lluvioso, en la plaza A solo hubo una muestra con esas larvas y en la plaza B no se encontraron parásitos. Los resultados revelaron la presencia de larvas de helmintos zoonóticos en el suelo de las plazas públicas de Caxias, Maranhão, principalmente en la época de lluvias, sirviendo de alerta a la población local.(AU)

Imported skin parasitosis.

Larva migrans cutanea is a typical skin parasitosis of tropical and subtropical regions. In Central European countries, such as Slovakia and Czech Republic, larva migrans cutanea is just an imported disease. Its clinical symptoms are characterized by formation of erythematous focus with serpiginous morphology, which is caused by migration of helminth in epidermis. The disease does not threaten the patient's life, but causes significant discomfort, especially in form of pruritus in the affected area. Thanks to growing trend of today's tourism more tourists are exposed to the harmful effects of the environment in final destinations. This leads to an increase in frequency of imported diseases, with which physicians in our latitudes may not have enough experience.

Autochthonous cutaneous larva migrans infection in Guipúzcoa. / Larva migrans cutánea de origen autóctono en Guipúzcoa.

INTRODUCTION: Cutaneous larva migrans (LM) infection forms a serpiginous eruption caused by the migration of nematode helminths through the epidermis. The parasites are acquired when the skin comes into contact with soil contaminated by the feces of infected animals. Until now, infections have been believed to be imported from tropical and subtropical regions. Our aim was to study cases of cutaneous LM diagnosed in residents of the Spanish province of Guipúzcoa who had not recently traveled to such regions. MATERIAL AND METHODS: Cross-sectional observational study of LM cases diagnosed in Hospital Universitario Donostia from 2011 to 2015 in patients who had not visited a region where this nematode infection is endemic. Clinical diagnoses were based on characteristic lesions. We studied the following variables: age, sex, site of lesions, date of onset of symptoms, possible source of contagion, pathologic findings, treatment, and clinical course. RESULTS: We found 4 cases, all in men (mean age, 60 years). Lesions were on the lower extremities in 3 patients and on the trunk in 1 patient. All had been in contact with soil that could have been contaminated by feces and was the most likely source of the parasite. The lesions disappeared after treatment with oral albendazole. CONCLUSIONS: The appearance of cases of autochthonous LM in Europe requires investigation of the culprit species, a review of the epidemiology of this infection, which was once considered imported, and the planning of public health measures to prevent it from becoming endemic.

Larva migrans cutánea tras un viaje al Caribe / Cutaneous larva migrans after a trip to the Caribean

Cutaneous larva migrans is a parasitic disease caused by Ancylostoma braziliense and Ancylostoma caninum larvae, which is transmitted by contact with sand infested with these parasites. Dogs and cats are the definitive hosts. This parasitic disease is endemic in the Caribbean, Africa, Australia, and Asia. We present the case of a 27-year-old woman, who developed skin lesions compatible with cutaneous larva migrans on her right foot after returning from beach vacations in the Mexican Caribbean. After clinical diagnosis, oral ivermectin was administered, with good clinical response.

La larva migrans cutánea es una parasitosis ocasionada por las larvas de Ancylostoma braziliense y Ancylostoma caninum, cuyo vehículo es la arena de playas infestadas. Los perros y gatos son los hospederos definitivos. Esta parasitosis es endémica en las costas del Caribe, África, Australia y Asia. Presentamos el caso clínico de una mujer de 27 años de edad, quien tras haber realizado un viaje al Caribe mexicano y haber estado en contacto con arena de playa, presentó unas lesiones en el pie derecho compatibles con larva migrans cutánea. El diagnóstico fue clínico. Recibió tratamiento con ivermectina oral, con buena respuesta.

Larva migrans cutánea en un paciente viajero portador de dishidrosis: a propósito de un caso clínico / Cutaneous larva migrans in a traveling patient with dyshidrosis: a case report

Larva migrans cutánea es el resultado de una infección por nematodos y muestra una erupción serpiginosa característica. Con el aumento de los viajes a zonas tropicales, muchos pacientes pueden volver con ésta infección, que es a menudo, mal diagnosticada o tratada incorrectamente. Esta enfermedad cutánea parasitaria es causada por la migración de larvas provenientes de animales en la epidermis humana.

Cutaneous larva migrans is a result of a nematode infection and shows a characteristic creeping eruption. As travel to the tropics zone increases, many patients may be returning with this infection, which is often misdiagnosed or treated incorrectly. This parasitic skin disease is caused by the migration of animal hookworm larvae in the human epidermis.

Presença de Toxocara spp. e ancilostomídeos em áreas de peridomicílios de uma comunidade pesqueira no Centro-Oeste do Brasil / Presence of Toxocara spp. and hookworms in peridomiciliary areas of a fishing community in the Mid-west region of Brazil

O objetivo do estudo foi verificar a contaminação do solo de peridomicílios de uma comunidade pesqueira localizadano município de Bonito, Mato Grosso do Sul, Brasil, onde é frequente a ocorrência de casos de Larva migrans cutânea.Utilizando-se das técnicas de centrifugo-flutuação, Baermann-Moraes e centrifugo- sedimentação, amostras de solo efezes de cães foram analisadas e os resultados evidenciaram altos índices de contaminação por ovos de Toxocara spp.,Ancilostomídeos e larvas de nematoides. Estes achados podem estar associados aos casos de Larvas migrans cutânea eàs elevadas taxas de eosinofilia em escolares daquela comunidade.

The aim of this study was to investigate soil contamination in peridomiciliary areas from a fishing community in themunicipality of Bonito, Mato Grosso do Sul state, Brazil, where is often found the occurrence of cases of cutaneous larvamigrans. Using the techniques of zinc sulphate centrifugal flotation, Baermann-Moraes and centrifugal sedimentation,soil samples and feces of dogs were analyzed and the results showed high levels of contamination by Toxocara spp.,hookworm and larvae of nematodes. These findings may be associated with cases of cutaneous larva migrans and highrates of eosinophilia in school children of that community.
