Dermatitis cercarial en bañistas del norte de la Patagonia Argentina / Cercarial dermatitis of bathers in northern Argentine Patagonia

La dermatitis cercarial es una enfermedad cutánea, zoonótica y estival, causada por una larva nadadora de trematodes de la familia Schistosomatidae, llamada cercaria. Esta larva penetra accidentalmente la piel de personas que se encuentran en el agua, generando una reacción alérgica que generalmente no se informa en centros de salud, dificultando el registro de su incidencia. Se han informado casos en todo el mundo, incluyendo a la Argentina, aunque los estudios epidemiológicos se han realizado solamente en el Hemisferio Norte. En este trabajo se estudió la epidemiología de la dermatitis cercarial en tres balnearios patagónicos de los lagos Pellegrini, Mari Menuco y Puelo, donde se realizaron encuestas a visitantes durante los veranos de 2012-2013 y 2013-2014. Se analizaron los factores de riesgo, que fueron agrupados en “características personales”, “uso del recurso” y “medidas de prevención”. En el lago Pellegrini fue la sensibilización de la persona incluida en "características personales" el único factor determinante para la ocurrencia de esta zoonosis, mientras que en el lago Mari Menuco la ocurrencia se asoció con el tiempo y la distancia a la costa y el uso de cremas. En el lago Puelo no se registraron casos durante el período de estudio.

The cercarial dermatitis is a zoonotic, summer, skin-disease, caused by a swimming larva (cercaria) of a schistosomatid trematode. This larva accidentally penetrates the skin of people in the water, causing an allergic reaction, which is not always reported in health centers, so it is difficult to determine its incidence. Cases have been registered worldwide, including Argentina, although the epidemiological studies were performed only in the Northern Hemisphere. In this survey the epidemiology of cercarial dermatitis was studied in three Patagonian lakes watering places, Pellegrini, Mari Menuco, and Puelo, where surveys were conducted during summers of 2012-2013 and 2013-2014. The risk factors were analyzed and grouped in “personal characteristics”, “use of the recreational resource”, and “prevention measures”. At the Pellegrini Lake, the people´s sensitivity included in "personal characteristics" was the only determining factor for the occurrence of this zoonosis, mean while in Mari Menuco Lake, the bathing time and distance from the coast, and the use of lotions would affect the occurrence of swimmer’s itch. In Puelo Lake, no cases were recorded during the study period.

An Outbreak of Caparinia tripilis in a Colony of African Pygmy Hedgehogs (Atelerix albiventris) from Korea

In February 2010, dermatitis characterized by scale and self-trauma due to puritis was recognized in a group of 22 four-toed hedgehogs (Atelerix albiventris Wagner, 1841) from a local pet shop in Gwangju, Korea. Microscopic examinations of skin scraping samples showed numerous mites of all developmental stages. Morphologically, pedicels of adult mites were short and unjointed. Tarsal caruncles were bell-shaped on all legs of males while they were absent on legs III and IV of females. Three long setae on the third pair of legs in both sexes were present. Adult males had posterior end of the abdomen with trilobate projection on each side, each lobe with a long seta. Based on these features, the mites were identified as Caparinia tripilis. This is the first report of caparinic mite infestation in hedgehogs from Korea. Identification keys for the family Psoroptidae and the genus Caparinia are provided.

Detección de las dermatosis más frecuentes en edad escolar: estudio de 800 niños en la Provincia de Santa Fe / Detection of school-age dermatoses: a study

Durante los meses de noviembre de 1996 a marzo de 1997, en dos localidades del sur de la provincia de Santa Fe (Roldán y Casilda), se procedió al examen dermatológico de 800 niños sanos, entre 5 y 13 años. La entrevista y el examen físico se realizaron en las escuelas primarias de ambas localidades. El protocolo incluía: datos personales, características fenotípicas del individuo, antecedentes familiares y personales de dermatosis y enfermedades cutáneas detectadas. Todos los niños recibieron tratamiento y fueron citados a un nuevo control. Las dermatosis más frecuentemente detectadas fueron: pediculosis, pitiriasis alba fascie, prurigo, escabiosis, verrugas vulgares, impétigo y dermatoficias. Consideramos que este tipo de detección de patologías de piel es una acción preventiva de salud y que el mejor ámbito para la prevención masiva en salud es la escuela

First reports of subcutaneous sparganosis in Sri Lanka.

OBJECTIVE: To report and create awareness of sparganosis, a parasitic zoonosis caused by a larval stage of Spirometra sp. SETTING: Two patients with non-tender subcutaneous lumps. DIAGNOSIS CRITERIA: Morphology of solid cestode larva in excision biopsies. CONCLUSIONS: Although these two instances were innocuous, infection is potentially dangerous as larvae are long lived and could invade vital organs. The most likely source of infection in Sri Lanka is ingestion of the infected first intermediate host, Cyclops, in water.

Current status of gnathostomiasis dorolesi in Miyazaki Prefecture, Japan.

Gnathostomiasis is an important food-borne parasitic zoonosis caused mainly by ingesting uncooked or undercooked flesh of freshwater fishes. Although four distinct species of the genus Gnathostoma were identified as the causative agents for human gnathostomiasis, human infections with G. doloresi have been found only in Japan, concentrated in Miyazaki Prefecture. So far we have found 25 cases in Miyazaki Prefecture. Although most of these patients were of cutaneous gnathostomiasis, two patients presented to the hospital with unusual clinical manifestations; one case was a pulmonary gnathostomiasis diagnosed by immunoserological methods, and the other was an ileus caused by migration of the late 3rd stage larva in the colonic tissue, which was found by post-operative histopathological examination. Although cutaneous lesions such as creeping eruption or mobile erythema are the common clinical features of gnathostomiasis, caution should be paid to the presence of such unusual cases.

Un caso de esparganosis humana en Argentina / A case of human sparganosis in Argentina

A male patient from Peru presented a nodule localized in the left costal region. All other clinical and laboratory data were normal. Upon biopsy, an helminth parasite emerged from the subcutaneous tissue, which presented a marked eosinophil infiltrate. The helminth was classified as a plerocercoid larva of Spirometra; the species was not determined. Since Spirometra are not common in Argentina, it is presumed that the patient was infested during his two year sojourn in the peruvian forest. Some epidemiological aspects are discussed. As far as we know, this is the first case of subcutaneous sparganosis and the second of sparganosis reported in Argentina.

Característica de las dermatosis en pediatría

Evaluamos las características epidemiológicas de 328 niños con dermatosis que consultaram al servicio de Dermatología del Hospital Infantil Dr. Robert Reid Cabral en un período de 6 meses. Las dermatosis más frecuentemente observadas fueron las dermatitis (31%) y las parasitosis cutáneas (14%). El grupo de edad más afectado fue el de los pre-escolares (31%). Cabe destacar el bajo porcentaje (0,7%) que ocuparan las consultas dermatológicas con relación a los demás servicios especializados. Esto podría estar relacionado con el cierre del departamento desde 1981 hasta el 1987
