An updated checklist of medusae and ctenophores is presented for the first time for the area comprised by the Bahía Blanca Estuary, the adjacent shelf El Rincón and Monte Hermoso beach, on the southwest coast of Buenos Aires province (Argentina). The area is highly productive and provides several ecosystem services including fishing and tourism. Updated information on the biodiversity of medusae and ctenophores species is essential for the study area, given that these species can affect ecosystem services. The list includes 23 hydromedusae, 3 scyphomedusae, and 3 ctenophores. Five hydromedusae (Halitiara formosa, Amphinema dinema, Aequorea forskalea, Clytia lomae and Halopsis ocellata) were firstly observed in this area. Three species of medusae, 2 hydromedusae (Olindias sambaquiensis and Liriope tetraphylla) and 1 scyphomedusae (Chrysaora lactea) pose a potential health risk, due to their toxicity to humans. Considering the size of the study area, the Bahía Blanca region has a comparatively high species richness of hydromedusae, higher than larger zones previously studied along the temperate SW Atlantic Ocean. The present report provides the baseline knowledge of gelatinous species for the Bahía Blanca region.

“…However, in this case, the increase in the number of records in the SINAN appears to be more related to the large outbreaks that occurred in the South and Southeastern regions in recent years, rather than with a permanent action for monitoring and notifi cation of accidents by cnidarians. Marques et al (31) reported approximately 20,000 accidents by jellyfi sh in the State of Paraná in the summer of 2011 to 2012 and presented several nonexclusive hypotheses to explain the occurrence of such a number of cases. One of these ideas involved an effi cient method of data collected by fi remen (lifeguards) and the health department during this season, which may indicate that the real number of accidents may not have been accurately reported in previous years with a high possibility of underreporting in the SINAN (31) .…”

Regarding accidents by sea urchins, Haddad Jr (13) (32) states that injuries by these animals are very common and represent over 50% of the occurrences with aquatic animals observed in the emergency services of the Southeastern coast of Brazil.…”

Introduction:We present a review of injuries in humans caused by aquatic animals in Brazil using the Information System for Notifi able Diseases [Sistema de Informação de Agravos de Notifi cação (SINAN)] database. Methods: A descriptive and retrospective epidemiological study was conducted from 2007 to 2013. Results: A total of 4,118 accidents were recorded. Of these accidents, 88.7% (3,651) were caused by venomous species, and 11.3% (467) were caused by poisonous, traumatic or unidentifi ed aquatic animals. Most of the events were injuries by stingrays (69%) and jellyfi sh (13.1%). The North region was responsible for the majority of reports (66.2%), with a signifi cant emphasis on accidents caused by freshwater stingrays (92.2% or 2,317 cases). In the South region, the region with the second highest number of records (15.7%), jellyfi sh caused the majority of accidents (83.7% or 452 cases). The Northeastern region, with 12.5% of the records, was notable because almost all accidents were caused by toadfi sh (95.6% or 174 cases). Conclusions: Although a comparison of different databases has not been performed, the data presented in this study, compared to local and regional surveys, raises the hypothesis of underreporting of accidents. As the SINAN is the offi cial system for the notifi cation of accidents by venomous animals in Brazil, it is imperative that its operation be reviewed and improved, given that effective measures to prevent accidents by venomous animals depend on a reliable database and the ability to accurately report the true conditions.

“…Although injuries due to cnidarians are observed sporadically on beaches around the world 1-3 , in the last five years there has been an increase in envenomations in the southern region of Brazil, especially in the States of Paraná and Santa Catarina, which record thousands of cases in the summer months (December, January, February, and March) 4,[5][6][7] .…”

“…Although there are other cnidarians in these regions that are capable of causing serious envenomations, with venoms associated with systemic phenomena and risk of death, they are much more rare and are not involved in severe injuries 5 . Among these, are the Portuguese man-of-war (Physalia physalis) and the cubomedusas (Tamoya haplonema and Chiropsalmus quadrumanus), with reports of deaths in humans after envenomations [5][6][7][8] .…”

Anaphylactic reaction/angioedema associated with jellyfish sting

The most frequent jellyfish in Southern Brazil causes mainly local pain and skin plaques. A 3-year-old female bather presented an erythematous, irregular plaque on the left forearm after contact with a jellyfish and intense facial angioedema with facial flushing. The lungs had vesicular murmur, wheezes, and snorts, and pink and spumous secretion in the airways with intercostal retraction. She was administered subcutaneous adrenaline (0.1mg/kg) and hydrocortisone intravenous (10mg/kg) with total recovery in a few minutes. The manifestations of anaphylactic reactions are distinct from those of envenomations, and prompt and adequate care is fundamental in these situations.
