TL;DR: Tungiasis acquired in Chaco Province, Argentina, a four - year old girl and her mother were assisted at the Hospital de Clinicas for 0.7 cm wide papules with a black central core and a white hyperkeratotic halo of fourteen days of development.
Abstract: Tungiasis acquired in Chaco Province, Argentina. A four - year old girl and her mother were assisted at the Hospital de Clinicas for 0.7 cm wide papules with a black central core and a white hyperkeratotic halo of fourteen days of development. The girl presented these lesions on the second and fourth toe of one of her feet, and her mother on the ankle. Among the known antecedents were a trip to Chaco Province and their habit of walking barefooted. After the papule incision, both antiseptic treatment and cleaning of the lesion, were performed. The exudate extracted from the wound was sent to the Parasitology laboratory for diagnosis. With low-power amplification (100 X), portions of an arthropod with numerous characteristic Tunga penetrans eggs were identified. The patients received antibiotic therapy and tetanus immunization. Tungiasis, which originated in America, is a cutaneous parasitosis caused by Tunga penetrans. In endemic areas, it is advisable to wear shoes in order to avoid the penetration of the flea into the skin. The presence of this flea should be suspected whenever hyperkeratotic papules with a black central core appear, mainly in the sub and periungual areas, soles, ankles and / or heels of the feet.

TL;DR: Sería conveniente recurrir a la utilización de técnicas de biología molecular para determinar if son especies distintas o diferentes estadios evolutivos de un mismo parásito.
Abstract: E. vermicularis es un pequeño nematode, de color blanquecino. El macho mide entre 3 y 5 mm de largo por 0,1 a 0,2 mm de ancho; su parte posterior es curva y presenta una espícula copulatoria. La hembra es recta y mide aproximadamente 10 mm de largo por 0,3 a 0,5 mm de ancho; su extremo posterior es aguzado y transparente. En enero de 2008 se remitieron a nuestro laboratorio tres vermes pequeños aislados de la zona perianal de una niña de 4 años de edad. Las manifestaciones clínicas eran prurito anal intenso y comportamiento nervioso. Las medidas de los tres ejemplares remitidos fueron las siguientes: 2,6 mm de largo por 0,4 mm de ancho, 3,2 mm de largo por 0,4 mm de ancho y 3,5 mm de largo por 0,5 mm de ancho. En la observación microscópica con un aumento de 40 X, no se halló en ningún ejemplar la espícula copulatoria en el extremo posterior. En la Figura 1 se observan dos ejemplares de E. vermicularis; el más pequeño, de color blanquecino, corresponde al estadio inmaduro; el de mayor tamaño, de color rosado, representa el estadio adulto hembra. En la Figura 2 se visualiza con más detalle el ejemplar inmaduro y se aprecia especialmente el extremo posterior en forma aguzada y transparente. En la Figura 3 se observa la presencia de dos expansiones cuticulares en el extremo anterior en forma de boquilla, típicas del género Enterobius. Algunos autores (1, 2) describen dos especies distintas de Enterobius spp. (E. vermicularis y E. gregorii) que se diferencian sobre la base de la longitud de las espículas de los machos. Recientemente, se ha sugerido que E. gregorii correspondería a un estadio inmaduro de E. vermicularis (3, 4), aunque no existe un acuerdo general al respecto. La singularidad del caso descripto reside en el hallazgo en la zona perianal de estadios inmaduros de E. vermicularis, que habitualmente se localizan en el intestino delgado. Sería conveniente recurrir a la utilización de técnicas de biología molecular para determinar si son especies distintas o diferentes estadios evolutivos de un mismo parásito.

TL;DR: El acaro Demodex folliculorum mide menos de 0,4 mm y habita principalmente en los foliculos pilosos de la frente, the nariz, las mejillas y los parpados, y se asocia with blefaritis y conjuntivitis.
Abstract: El acaro Demodex folliculorum mide menos de 0,4 mm y habita principalmente en los foliculos pilosos de la frente, la nariz, las mejillas y los parpados. Otra especie de menor tamano, Demodex brevis, se localiza en las glandulas sebaceas. La via de infestacion se desconoce, aunque se postula su transmision por contacto directo entre las personas. Estos artropodos se alimentan de secreciones y descamaciones de la piel. Las hembras ponen hasta 25 huevos en un solo foliculo. Su ciclo de vida tiene una duracion aproximada de 3 a 4 semanas. Demodex spp. se relaciona con la presencia de acne, comedones (puntos negros), queratitis localizada y dermatitis. Tambien se asocia con blefaritis y conjuntivitis. Se documenta el caso de una mujer de 56 anos que concurrio al medico dermatologo por una erupcion de tipo rosacea alrededor de la boca, sugestiva de una demodecidosis. Las muestras fueron extraidas mediante la aplicacion de cintas adhesivas transparentes sobre las lesiones de la piel, que posteriormente se adhirieron a portaobjetos para la busqueda del acaro mediante la observacion al microscopio optico. Con este procedimiento se observaron ejemplares adultos de Demodex spp. (Figura). Se destaca la importancia de sospechar la infestacion por Demodex spp. en el caso de pacientes que consultan por acne, rosacea, dermatitis seborreica o blefaritis cronica, esta ultima resistente a los tratamientos habituales.

TL;DR: The first finding of Diphyllobothrium sp.
Abstract: This paper reports the first finding of Diphyllobothrium sp. eggs in Canis familiaris (domestic dog) from Puerto Iguazu, a subtropical city of Misiones province, Argentina. In 2013, two positive cases of Diphyllobothrium sp. eggs were detected during an annual parasitological survey of dogs. Dog feces were collected in vials containing 10% formalin and processed using Telemann's sedimentation and Sheather's flotation techniques. The two cases were detected in rural areas of the municipality. Since Misiones is not a part of the endemic area of diphyllobothriasis and given the fact that it is located in the three-border area of Argentina, Brazil and Paraguay, we consider this finding of great importance to public health. We stress the need for updating the current knowledge about the life cycle of these parasites considering the range of intermediate and definitive hosts, their zoonotic potential, and the epidemiological situation in non-endemic areas.

TL;DR: The best treatment option is the surgical extraction of the flea under aseptic conditions, and the disease is associated to multiple complications such as: loss of digits; tetanus and potentially lethal bacterial infections.
Abstract: Tungiasis is a parasitic disease caused by hematophagous fleas of the Tunga genus. It is undoubtedly related with poverty and its prevalence in endemic areas is 15-55 %. The disease develops when the gravid tunga female penetrates the skin of an homeothermic susceptible host, usually a human being, and suffers a process of hypertrophy lying thousands of eggs that are expelled to the environment where the life cycle is completed. The feet are the most frequently affected in bare foot patients; however, any part of the body can be affected. The lesions are nodules with a central black opening, very pruritic corresponding to the posterior part of the flea’s abdomen. The disease is self-limited and it resolves spontaneously in 4-6 weeks. However, reinfestation is frequent seen and the disease is associated to multiple complications such as: loss of digits; tetanus and potentially lethal bacterial infections. The best strategy for disease control is to prevent the infestation; however, the best treatment option is the surgical extraction of the flea under aseptic conditions. keywords: Tungiasis, Tunga penetrans, flea infestations, poverty, complications, therapy, prevention and control. Introducción La tungiasis es una parasitosis cutánea causada por pulgas hematófagas, siendo Tunga penetrans la principal especie responsable. Se han reportado casos causados por Tunga trimamillata en Ecuador y en Perú. La primera especie fue descrita por Linnaeus en el siglo XVIII, la segunda por Pampiglione y col. en el año 2002. Es una zoonosis causada por pulgas pertenecientes al Phylum Arthropoda, Clase Insecta, Orden Siphonaptera, Familia Tungidae y al Género Tunga.

TL;DR: A case of a 10-years-old girl, with multiple lesions localized on feet, who was succesfully treated with ivermectin and surgical removal of lesions is described.
Abstract: Tungiasis, is a cutaneous parasitosis, native of America caused by Tunga penetrans. Infestations usually presents with black papular lesions, either single or multiple, most of them localized on the feet, mainly in the subungual and periungual areas. Diagnosis of tungiasis is based on the characteristic aspect of the lesions in a patient coming from an endemic area. Surgical removal of the flea and application of a topical antibiotic is the standard treatment. We describe a case of a 10-years-old girl, with multiple lesions localized on feet, who was succesfully treated with ivermectin and surgical removal of lesions.
