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 manifes...

conclusions our data suggest that using polyvalent antivenom in short time after envenomation could reduce the inflammatory responses related to the systemic changes during the elevation of cytokines in scorpion envenomation. results il-1a, il-6, and tnf-α levels were significantly increased in 3 hours after envenomation in both groups (v and av), but the intensity of increase in av group was l...

In Israel, Vipera palaestinae (V. palaestinae) is the most common venomous snake, accounting for 100-300 reported cases of envenomation every year. However, V. palaestinae snakebites in children have not been extensively investigated. The demographic features, treatment and outcome of V. palaestinae envenomation in 37 children treated in two medical centers over a 9 year period were retrospecti...

Declared as a neglected disease by the OMS, snakebites are responsible for 421,000 cases of envenomation and 20,000 deaths worldwide. In Morocco, they much rarer but remain serious with heavy consequences. It is exceptional to observe mesenteric infarction following bugloss envenomation. The physiopathological mechanism not clearly established, seems multifactorial. context multivisceral failur...

We present a normal 13-year old female who developed left cerebral infarction following envenomation by the carpet viper (Echis carinatus). We have read of only one other case of cerebral infarction following viper envenomation (Viperi russelli). Possible mechanisms for cerebral infarction in these circumstances are discussed. It is believed that this complication may be more common than is rep...

IntroductionTissue damage, inflammatory response, and hematologic abnormalities may occur in snakebite envenomation. This study aimed to evaluate the predictive ability of platelet distribution width (PDW) lymphocyte ratio (PDWLR) severity outcome envenomation patients with snakebites emergency department (ED).MethodsAll adult admitted ED after a were retrospectively evaluated. Patients classif...

Envenomation of domestic animals by snakes occurs frequently in certain geographic areas. However, reports describing clinical signs, clinicopathologic abnormalities, therapeutic approaches, and outcomes are sparse. This review summarizes various snake families, venom types associated with harmful snakes, and the significant hematologic, hemostatic, and biochemical abnormalities associated with...

We discuss the case of a 52-year-old woman who developed urticarial lesions after the acute envenomation of a puss caterpillar (Megalopyge opercularis). The puss caterpillar, one of more than 50 species of caterpillars that can cause envenomation in the United States, is considered to be one of the most serious. Its clinical presentation and current recommended treatments are reviewed.
