ABSTRACT
La picadura de la medusa o agua viva Olindia sambaquiensis es de ocurrencia frecuente en las playas de la costa de la provincia de Buenos Aires. Se notifican entre quinientas y mil picaduras de medusas por temporada en la localidad balnearia de Monte Hermoso, al sur de la provincia de Buenos Aires. El daño cutáneo que provoca por su elevada acción urticante plantea un serio inconveniente para el desarrollo del turismo. Durante el mes de enero de 1998, en la localidad de Monte Hermoso se reunieron un total de 49 casos que fueron examinados dentro de la hora posterior a la picadura. Veintiocho eran de sexo masculino (57.1%). La edad promedio fue de 16 ± 4.1 (rango 5-80). El 54% presentó lesiones eritemato-edematosas de configuración lineal, el 28% presentó lesiones predominantemente eritematosas y el 18% presentó placas eritemato-edematosas. En el 73% de los casos las lesiones se localizaron en miembros inferiores. Hemos redefinido la lesión cutánea producida por la medusa O. sambaquiensis, su evolución, sus dimensiones y localizaciones más frecuentes. Además, se ha tipificado y cuantificado el dolor que produce, y otros signos y síntomas que acompañan a la picadura en la hora posterior, a las primeras 24 horas y a los 30 días. Describimos las conductas terapéuticas utilizadas en nuestra costa, evaluamos la efectividad de algunas de ellas en el control del dolor y finalmente proponemos un esquema terapéutico para dicha picadura.
Olindias sambaquiensis jellyfish sting occurs frequently in Buenos Aires province coast beaches. Among five hundred and one thousand stings by jellyfish are reported each season at Monte Hermoso, a beach village in the South of Buenos Aires province. The skin damage provoked because of its highly irritant effect poses a serious issue related to tourism development. A total number of 49 cases that were examined during the first hour after the sting were enrolled in Monte Hermoso during January 1998. Twenty eight were males (57.1%). The average age was 16 ± 4.1 (range 5-80). Of them, 54% showed linear erythema-edematous lesions, 28% showed predominantly erythematous lesions, and in 18% the injuries were erythema-edematous plaques. In 73% of the cases the lesions were located in lower limbs. We had hereby redefined cutaneous lesions produced by O. sambaquiensis, its evolution, its dimensions and most frequent localizations. Besides, it has been typified and quantified the pain it provokes and other signs and symptoms that go with the sting during the posterior hour, during the first 24 hours, and after 30 days. We described the therapeutic conducts used in our coasts and we assessed the effectiveness of some of them in pain control, and finally we propose a therapeutic scheme for this sting.

Seabather's eruption is characterized by the occurrence of intensely itchy erythematous papules observed mainly in the region covered by swimwear. The dermatitis occurs due to the contact of planula larvae of scyphomedusae Linuche unguiculata with the skin. The swimsuit pressure triggers the action of the poisonous stinging structures carried by the larvae. The case described occurred in a child who, while bathing in the ocean waters of the Northeast coast of Bessa's Beach located in the city of Joao Pessoa, state of Paraiba, showed typical clinical signs of the disease. It was concluded that the report of the case showed clinical and therapeutic implications for doctors working in all of the Brazilian coastal areas.
O prurido do traje de banho é uma erupção caracterizada por pápulas eritematosas, intensamente pruriginosas, localizadas principalmente sob os trajes dos banhistas de mar. A dermatite ocorre pelo contato com as larvas plânulas da cifomedusa Linuche unguiculata que disparam seus nematocistos na pele do acidentado a partir das suas células de defesa, os cnidócitos. O caso ocorreu em uma criança que ao se banhar nas águas oceânicas do litoral da Região Nordeste na Praia do Bessa localizada na cidade de João Pessoa, Estado da Paraíba, apresentou quadro clínico típico da enfermidade. Concluiu-se que o relato do caso evidenciou implicações clínicas e terapêuticas para os médicos que atuam em todas as áreas litorâneas brasileiras.
