BACKGROUND Venom recurrence or persistence in the circulation after antivenom treatment has been documented many times in viper envenoming. However, it has not been associated with clinical recurrence for many snakes, including Russell's viper (Daboia spp.). We compare the recovery of coagulopathy to the recurrence or persistence of venom in patients with Russell's viper envenoming. METHODOLO...

Envenoming by Echis ocellatus is potentially life-threatening due to severe hemorrhage, renal failure and capillary leakage. These effects are attributed snake venom metalloproteinases (SVMPs). ...

BACKGROUND Death adders (Acanthophis spp) are found in Australia, Papua New Guinea and parts of eastern Indonesia. This study aimed to investigate the clinical syndrome of death adder envenoming and response to antivenom treatment. METHODOLOGY/PRINCIPAL FINDINGS Definite death adder bites were recruited from the Australian Snakebite Project (ASP) as defined by expert identification or detecti...

AIM This case report presents envenoming by the Chinese pit viper Protobothrops mangshanensis (formerly Zhaoermia) and its treatment. METHODS A 38 year old snake breeder suffered two-fang bites to elbow by a Chinese pit viper Protobothrops mangshanensis resulting in local edema of the affected arm. No other signs of envenoming appeared. On the 5(th) day following the bite a hematoma developed...

Scorpion stings are very frequent in Tunisia; yet a method for evaluating envenoming severity and consequently victim treatment, has never been adequately established nor has its efficiency been properly evaluated. Indeed, a management of envenomed patients requires the optimization of envenoming antivenom immunotherapy. This task requires either, an accurate evaluation of toxicokinetic paramet...

Snakebite envenoming is a major public health burden in tropical parts of the developing world. In sub-Saharan Africa, neglect has led to a scarcity of antivenoms threatening the lives and limbs of snakebite victims. Technological advances within antivenom are warranted, but should be evaluated not only on their possible therapeutic impact, but also on their cost-competitiveness. Recombinant an...

Fishes of family Batrachoididae are responsible for great number of injuries in fishermen in North and Northeast regions of Brazil. The genus Thalassophryne presents various venomous species of fishes found in the Brazilian coast, T. nattereri being the most common of them. The venom is ejected through two hollow spines on the dorsal fin and two on pre-opercular regions, which present a venomou...

The objective of this study was to evaluate the effects of two different dosage protocols on the outcome of patients with severe neurotoxic snake envenoming, using a retrospective analysis of patients admitted with a diagnosis of severe neurotoxic snake bite over a 4 year period. In the study, 55 snake bite victims requiring ventilatory support for severe neurotoxic envenoming received either 1...

Hypnale hypnale (hump-nosed pit viper) is a medically important venomous snake in Sri Lanka and Southwestern India. Bite of this snake may result in hemostatic dysfunction, acute kidney injury and death. Clinical studies indicated that the locally available polyvalent antivenoms produced in India are not effective against hump-nosed pit viper envenoming. Hence, there is an urgent need to search...

Death due to poisonous scorpion (Buthidae family) stings is a common event in the developing countries. Scorpion envenoming syndrome results in autonomic storm, release of catecholamines, angiotensin II, glucagon, glucocorticoids, either suppressed insulin secretion or hyperinsulinemia; hyperglycemia, lipolysis – sudden increase in free fatty acids (FFA), acute myocarditis, disseminated intrava...
