Clinical characteristics of redback spider bites.

Background: Redback spiders (Latrodectus hasselti) (RBSs) are venomous spiders that have recently spread to Asia from Australia. Since the first case report in 1997 (Osaka), RBS bites have been a clinical and administrative issue in Japan; however, the clinical characteristics and effective treatment of RBS bites, particularly outside Australia remains unclear. This study aimed to elucidate the clinical characteristics of RBS bites and to clarify the effectiveness of the administration of antivenom for treatment.

Effect of antivenom therapy of Rhabdophis tigrinus (Yamakagashi snake) bites.

Background: Rhabdophis tigrinus (Yamakagashi snake) is a rear-fanged colubrid snake present throughout Russia and Asia. Its venom induces life-threatening hemorrhagic symptoms and severe disseminated intravascular coagulation with a fibrinolytic phenotype. R.

Rhabdophis tigrinus is not a pit viper but its bites result in venom-induced consumptive coagulopathy similar to many viper bites.

As a response to the recent article by Hifumi et al. published in the Journal of Intensive Care, the present correspondence clarifies the family-level taxonomy of the yamakagashi (Rhabdophis tigrinus). Further, the relevance of the term 'venom-induced consumptive coagulopathy,' instead of disseminated intravascular coagulation, in describing the procoagulant coagulopathy of R.

Potentially fatal coagulopathy secondary to yamakagashi () bites that completely recovered with antivenom treatment.

Case: A healthy 40-year-old man was admitted with severe coagulopathy that developed after bites. On admission, he showed significantly elevated levels of thrombin-antithrombin III complex (60 ng/mL), plasmin-alpha 2-plasmin inhibitor complex (22.3 μg/mL), and fibrinogen degradation products (592 μg/mL).

Clinical characteristics of yamakagashi (Rhabdophis tigrinus) bites: a national survey in Japan, 2000-2013.

Background: Yamakagashi (Rhabdophis tigrinus) is a species of pit viper present throughout Russia and Eastern Asia. Although R. tigrinus venom is known to induce life-threatening hemorrhagic symptoms, the clinical characteristics and effective treatment of R.
