Skin lesions in envenoming by cnidarians (Portuguese man-of-war and jellyfish): etiology and severity of accidents on the Brazilian coast

This work attempts to establish dermatological identification patterns for Brazilian enidarian species and it probable correlation with envenoming, severity In all observational prospective study, one hundred and twenty-eight patients from the North Coast re-ion of São Paulo State, Brazil were seen between 2002 and 2008. About 80% of these Showed only local effects (erythema, edema, and pain) with small, less than 20 cm, oval or round skin marks and impressions from Small tentacles. Approximately 20% of the victims had long, more than 20 cm, linear and crossed marks with frequent systemic phenomena, such as malaise, vomiting, dyspnea, and tachycardia. The former is compatible with the common hydromedusa from Southeast and Southern Brazil (Olindias sambaquiensis). The long linear marks with intense pain and systemic phenomena are compatible with envenoming, by the box jellyfish Tamoya haplonema and Chiropsalmus quadrumanus and the hydrozoan Portuguese man-of-war (Physalis physalis). There was an association between Skin marks and probable accident etiology. This simple observation rule can be indicative of severity as the Cubozoa Class (box jellyfish) and Portuguese man-of-war cause the most severe accidents. In such cases, medical attention, including intensive care, is important, as the systemic manifestations call be associated with death.

An outbreak of Portuguese man-of-war (Physalia physalis - Linnaeus, 1758) envenoming in Southeastern Brazil

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.

Epidemiology of the Cnidarian Physalia physalis stings attended at a health care center in beaches of Adicora, Venezuela

Stings caused by jellyfish and jellyfish-like colonies are common all around the world, with serious manifestations and occasional deaths reported in some countries. Between December 2006 and 2007, epidemiological, clinical and treatment aspects of stings caused by the Portuguese man-of-war (Physalia physalis) in 59 patients consulting the ambulatory emergency in Adicora, Falcon State, Venezuela, were studied. Most of the stings occurred in males (59%) preschool and school-aged children (49%), visitors from other areas of the country (92%) during holidays when bathing or diving at the beach (97%). Injuries presented linear erythematous plaques at the point of contact with the animal, located in several anatomical sites. Most clinical manifestations observed were: intense burning pain, urticaria, erythema and inflammation (100%), as well dyspnea with laryngeal edema and fever (19%). Patients were treated with topical drugs, including antihistamine and antipyretic drugs, but also with systemic hydrocortisone. P. physalis stings in Adicora appeared to have a seasonal pattern, with systemic complications potentially life-threatening. Thus, epidemiological surveillance program is recommended, particularly in travelers. (C) 2012 Elsevier Ltd. All rights reserved.

Animais aquáticos de importância médica no Brasil

The injuries caused by venomous and poisonous aquatic animals may provoke important morbidity in the victim. The cnidarians (jellyfishes, especially cubomedusas and Portuguese-Man-of-War) caused nearly 25% of 236 accidents by marine animals, while sea urchins were responsible for about 50% and catfish, stingrays and scorpionfish nearly 25%). In freshwater, stingrays and catfish cause injuries with a very similar mechanism to the poisoning and the effects of the toxins of marine species. In a series of about 200 injuries observed among freshwater fishermen, nearly 40% were caused by freshwater catfish, 5% freshwater stingrays and 55% by traumatogenic fish, such as piranhas and trairas. The author presents the aquatic animals that cause injuries to humans in Brazil, the clinical aspects of the envenoming and the first measures for the control of the severe pain observed mainly in the accidents caused by cnidarians and venomous fishes.

The presidential persona paradox of Barack Obama : man of peace or war president?

On a wave of hope and rousing talk of building global bridges, President Barack Obama won office in 2008, in part on a pledge to end the wars in Afghanistan and Iraq and to close the Guantanamo Bay detention facility. In contrast to his predecessor, who launched America into long, costly and ineffectual wars, Obama was seen to be more of a dove than a hawk. However, at the end of his two-term tenure America has been in a state of foreign belligerence for all eight years, making Obama the longest serving U.S. war president in history.The political persona of Obama as a dove originated with his opposition to the 2003 intervention in Iraq while he was still a senator. This was then cemented early in his presidency with his 2009 speech in Cairo, which seemed to signal a profound and optimistic realignment of America’s intentions towards the Middle East and its peoples. This speech was a watershed in defining his political persona and was instrumental in his being the only U.S. president to be awarded a Nobel Peace Prize while still in office. However, during his term the underlying political landscape of the Middle East changed significantly, with the withdrawal from then return to Iraq, the nuclear agreement with Iran, the increasingly chaotic legacy of the Arab Spring, the continued impasse of the Israel-Palestinian peace, the disintegration of Yemen and Libya and the rise of the Islamic State as the new threat in the political vacuum of northern Iraq and eastern Syria, and a resurgent Russian role in the region. All of these have provided novel challenges to Washington and a president attempting to live up to the positivity of his early days in office.At the end of his presidency Obama is faced with a public burned by the disappointments of the Iraq and Afghanistan campaigns and the new entanglements in the Middle East. This paper seeks to offer insights into the juxtaposition of Obama’s political persona and reality, as well as exploring what his political legacy might really be.
