BITE OF A POISONOUS SPIDER, LATRODECTUS MACTANS.

Development of Latrodectus Envenomation Severity Score (LESS); a Severity Index for Widow Spider Bite: Initial Step

Background: In order to describe the patients and evaluate the effectiveness of treatments for widow spider envenomation, investigators require a reliable assessment tool. In this paper, the development of a clinical index for measuring the widow spider bite severity, Latrodectus Envenomation Severity Score (LESS), is described. Methods: According to the valid methods for index development, a D...

The treatment of black widow spider envenomation with antivenin latrodectus mactans: a case series.

Black widow spiders (Latrodectus mactans) are found throughout the US. Though bites are relatively uncommon, they pose a significant health problem with over 2500 reported to American poison control centers annually. Black widow spider bites cause a characteristic envenomation syndrome consisting of severe pain, muscle cramping, abdominal pain, and back pain. The significant pain associated wit...

Some effects of the venom of the Chilean spider Latrodectus mactans on endogenous ion-currents of Xenopus laevis oocytes.

A study was made of the effects of the venom of the Chilean spider Latrodectus mactans on endogenous ion-currents of Xenopus laevis oocytes. 1 microg/ml of the venom made the resting plasma membrane potential more negative in cells voltage-clamped at -60 mV. The effect was potentially due to the closure of one or several conductances that were investigated further. Thus, we determined the effec...
