Resumo: ABSTRACT INTRODUCTION: The clinical and epidemiological aspects associated with Portuguese man-of-war envenomation were investigated and characterized. METHODS: Data from recorded envenomation events between 2005 and 2013 were provided by the GBMar (Group of Firemen Maritime of Maranhão State) and SEMUSC (Municipal Secretary of Security with Citizenship). RESULTS: Most victims were children, and clinical manifestations included intense pain, edema, erythema, and rare systemic manifestations. CONCLUSIONS: The envenomation events were predictable and based on patterns involving multiple factors (environmental and/or human behavior); however, the initially applied measures did not match the current recommendations of the Health Ministry of Brazil.

Idioma: en.
Resumo: Abstract INTRODUCTION: The Portuguese man-of-war (Physalia physalis) is a cosmopolitan species, with a widespread distribution and responsible for a great number of injuries caused by cnidarians worldwide, including Brazil. Geoprocessing technology, however, has never been used to assess the spatial distribution of these animals on beaches. The aim of this study was to carry out a health risk assessment of Portuguese man-of-war (P. physalis) envenomations on the São Marcos and Calhau beaches in São Luís city, in the state of Maranhão, Brazil. METHODS: This is a descriptive and quantitative study concerning primary data on the occurrence of the Portuguese man-of-war (P. physalis) and human envenomations in the studied places, conducted over a two-year period in São Luís, Maranhão, northeastern Brazil. RESULTS: Envenomations mainly occurred on beaches presenting high density of P. physalis during the dry period. Vinegar has been incorporated as a first aid, according to recommendations set by the Brazilian Ministry of Health. CONCLUSIONS: In order to improve prevention and control actions of human envenomation, risk areas for this type of envenomation should be clearly indicated as alert areas. Inclusion of the geographical location of the envenomation in the Notification/Investigation SINAN Form was suggested for allowing the continuity of studies involving this public health issue.

Título: Dermatitis de los bañistas asociada al contacto con la medusa -liriope tetraphylla- en Monte Hermoso, Buenos Aires, Argentina / Sea bathers' dermatitis caused by contact with the medusa -liriope tetraphylla- in Monte Hermoso beach, Buenos Aires, Argentina
Fonte: Rev. Asoc. Med. Bahía Blanca;26(2):43-49, abrul-junio 2016.
Idioma: es.
Resumo: Desde el año 2013 es frecuente encontrar a la medusa Liriope tetraphylla en las costas de Monte Hermoso y zonas aledañas de la Provincia de Buenos Aires. En los últimos años se ha podido registrar un número importante de afectados por picaduras de Liriope tetraphylla. Cuando las picaduras son abundantes producen el fenómeno de "tapioca" o "pica- pica", provocando en forma inmediata ardor leve y luego lesiones pápulo-eritema-edematosas con picazón intensa. Las lesiones tienen una distribución específica en zonas de flexión corporal y lugares cubiertos por el traje de baño. El día 15 de febrero de 2015 se registró un "bloom" de L. tetraphylla, con una densidad de 605 individuos/m3, que se vio reflejado en el gran número de personas afectadas que ingresaron el Servicio de Emergencias del Hospital Municipal de Monte Hermoso "Dr. Ramón Carrillo" el día 16 de febrero de 2015. De un número total de 71 pacientes adultos que ingresaron ese día al Servicio, fueron atendidos por dermatitis asociada al contacto con "tapioca" 19 de ellos (26.80%),y de un total de 69 pacientes pediátricos, 49 de ellos (71%) fueron tratados por la misma afección. En el presente trabajo se detallan los síntomas causados por "tapioca" en base a 68 casos tratados. Se describe el tratamiento utilizado y métodos de prevención para las lesiones, así como su relación con el bloom de la especie de aguaviva en cuestión.

Since the summer of 2013 the sea medusa Liriope tetraphylla was found frequently on the shores of Monte Hermoso and nearby beaches in Buenos Aires Province. Recently, there has been a significant number of sea bathers affected by Liriope tetraphylla bites. When the bites are numerous, a phenomenon called "tapioca" or "pica - pica" occurs, thus causing immediate mild burning followed by erythematous-edematous papulas and intense itching. Lesions have a specific distribution in body flexion parts and body areas covered by the bathing suit. In February 15, 2015 there was a L. tetraphylla bloom, recording a density of 605 individuals/m3, that caused a large number of sea bathers to present dermatitis and receive treatment at the Emergency Service of Dr. Ramón Carrillo Hospital in Monte Hermoso. On this day, 19 out of 71 adults (26.80%) and 49 out of 69 children (71%) who were treated at the Emergency Service showed clinical profiles compatible with the contact with the sea medusa. In this work, the symptoms caused by "tapioca" based on 68 cases are described in detail, as well as the medical treatment applied, the preventive methods for medusa bites, and the relation with the medusa bloom.

Título: An outbreak of Portuguese man-of-war (Physalia physalis - Linnaeus, 1758) envenoming in Southeastern Brazil
Fonte: Rev. Soc. Bras. Med. Trop;46(5):641-644, Sept-Oct/2013. graf.
Idioma: en.
Resumo: Introduction Portuguese man-of-war, Physalia physalis (Linnaeus, 1758), are cnidarians capable of discharging intracellular organelles filled with venom, resulting in severe envenomation in humans. Methods We report the clinical and therapeutic aspects of 331 accidents involving Portuguese man-of-war in an outbreak on the coast of the State of São Paulo, Brazil. Results The clinical manifestations of envenomation were rare and mild and mostly local, systemic reactions; there was a low rate of late complications. Conclusions The consequences of envenomation were of moderate severity, and first aid measures were effective in controlling the pain. Outbreaks of accidents involving Portuguese man-of-war occur periodically in the area without a clear explanation. .

Título: Medusas (Cnidaria: Hydrozoa) de una zona de afloramiento costero, Bahía Culebra, Pacífico, Costa Rica / Medusae (Cnidaria: Hydrozoa) from a coastal upwelling zone, Culebra Bay, Pacific, Costa Rica
Fonte: Rev. biol. trop;60(4):1731-1748, Dec. 2012. ilus, graf, mapas, tab.
Idioma: es.
Resumo: The hydromedusae have an important role in marine trophic webs due to their predatory feeding habits. This is the first study of this group of gelatinous marine zooplankton in a coastal upwelling area of Central America. The composition and abundance variability of hydromedusae were studied during six months in 1999 at four stations in Culebra Bay, Gulf of Papagayo, Pacific coast of Costa Rica (10º37’ N-85º40’ W). A total of 53 species were identified, of which 26 are new records for Costa Rica, 21 are new records for Central America, and eight are new records for the Eastern Tropical Pacific. The more abundant species (more than 30% of the total abundance) were Liriope tetraphylla, Solmundella bitentaculata and Aglaura hemistoma. Six species occurred throughout the sampling period, 10 were present only during the dry season (December-April), and 17 were so during the rainy season (May-November). Significant differences of medusan abundances were found between seasons (dry vs. rainy). Maximum abundance (2.1±4.3ind./m³) was recorded when upwelled deeper water influenced the Bay, as indicated by local higher oxygen concentrations and lower water temperatures. The relatively high species richness of medusae found in Culebra Bay is probably related to factors like the pristine condition of the Bay, the arrival of oceanic species transported by the Equatorial Counter Current (ECC), the eastward shoaling of the Costa Rica Dome, and local currents. Illustrations of the 15 more important species are included to facilitate their identification and foster future work in the region.

Las hidromedusas tienen un papel importante en redes tróficas marinas debido a sus hábitos alimenticios depredadores. Este es el primer estudio de este grupo del zooplancton gelatinoso en un area de afloramiento costero en América Central. Durante seis meses de 1999, se estudió la abundancia de hidromedusas en cuatro estaciones en Bahía Culebra, Golfo de Papagayo, costa Pacífica de Costa Rica (10º 37’N-85º40’W). Se identificó un total de 53 especies de las que 26 son registros nuevos para Costa Rica, 21 son registros nuevos para América Central y 8 son nuevos registros para el Pacífico Oriental Tropical. Las especies más abundantes durante el estudio (con más de 30% de la abundancia total) fueron Liriope tetraphylla, Solmundella bitentaculata y Aglaura hemistoma. Seis especies se presentaron en todos los muestreos, 10 especies se presentaron únicamente durante la época seca y 17 se presentaron únicamente durante la época lluviosa. Se mostraron diferencias significativas entre las épocas lluviosa y seca. La máxima abundancia promedio de hidromedusas (2.1±4.3 ind./m³) fue encontrada durante las fechas que se espera el afloramiento costero, indicado por alta concentración de oxígeno y baja temperatura. La rica composición de especies encontrada en Bahía Culebra puede ser el resultado de varios factores, incluyendo la condición prístina de la bahía, el transporte de especies por la Contra Corriente Nor-Ecuatorial (NECC) y los aportes de origen terrestre. Se incluyen ilustraciones de las 15 especies más importantes para facilitar su identificación y promover estudios futuros en la región.

Título: Picadura de medusa Olindias sambaquiensis: Análisis de 49 casos
Fonte: Medicina (B.Aires);72(5):380-388, oct. 2012. ilus.
Idioma: es.
Resumo: 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.

Idioma: en.
Resumo: We report the case of a 42-year old woman who was envenomed by a Portuguese man-o'-war (Physalia physalis). She presented an anomalous reaction manifested by purpuric papules that appeared after the initial phase of envenoming (around 24 hours later), when linear erythematous and edematous papules were observed. Late-onset reactions in accidents involving cnidarians commonly include chronic eruptions and local pigmentation.

Os autores relatam um envenenamento causado por um cnidário, a caravela (Physalia physalis), em uma mulher de 42 anos. A paciente apresentou uma reação incomum manifestada por pápulas purpúricas surgidas após a fase inicial de envenenamento (cerca de 24 horas depois) quando foram observadas pápulas lineares edematosas e eritematosas. As reações tardias nos acidentes por cnidários comumente apresentam erupções recorrentes e pigmentações locais.
