MOSOVICH, Juan H  and  YOUNG, Pablo. Picadura de medusa Olindias sambaquiensis: Análisis de 49 casos. Medicina (B. Aires) [online]. 2012, vol.72, n.5, pp.380-388. ISSN 0025-7680.

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.
