  Venom induced pressure elevation reversible syndrome: a severe pediatric rattlesnake envenomation, evidence for conservative management, and call for naming the syndromeVenom induced pressure elevation reversible syndrome: a severe pediatric rattlesnake envenomation, evidence for conservative management, and call for naming the syndrome Abstract Introduction : Rattlesnake envenomation frequently mimics traumatic compartment syndrome, as both are characterized by severe pain, swelling, and elevated compartment pressures. Unlike traumatic compartment syndrome there have been no documented cases of ischemic limb injury after envenomated patients have received antivenom. Furthermore, there is experimental evidence that fasciotomy worsens myonecrosis. This has led medical toxicologists and surgical guidelines to shift from liberally recommending fasciotomy to near universal recommendation of antivenom alone. Despite this, fasciotomies continue to be recommended and performed on rattle...

First case of gynandromorphy in the spider family Zodariidae (Arachnida: Araneae)

Abstract
Gynandromorphy has been documented in a variety of spider taxa, including at least fifteen families, but it remains rare relative to the overall diversity of spiders. In this study, we report a case of gynandromorphy in an ant-eating spider, Mallinella sp. (Araneae: Zodariidae), in which a single individual exhibits sexual characteristics of both sexes, along with deformed male and female genitalia. This is the first report of gynandromorphy in the family Zodariidae.
