  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...

Expanding the horizon: Discovery of two new spider species of the Pholcus phungiformes species group (Araneae, Pholcidae) from Inner Mongolia, China, with a new western record for the group

Abstract

The spiders of the Pholcus phungiformes species group are primarily distributed across five mountain ranges in East Asia: the Lüliang Mountains and the Yanshan-Taihang Mountains in North China, the transitional uplands between the Yanshan-Taihang and Changbai Mountains, the Changbai Mountains straddling the China-North Korea border, and the Taebaek-Sobaek Mountains on the Korean Peninsula. In this study, we report the first records of this group from Inner Mongolia, northern China, describing two new species: Pholcus alashan Wang & Yao, sp. nov. (♂♀, from Alashan Zuoqi) and P. chifeng Yan & Yao, sp. nov. (♂♀, from Chifeng). The discovery of P. alashan sp. nov. extends the group’s western distribution limit by 5.2° longitude (from c. 111.0°E to 105.8°E), representing a significant zoogeographic range expansion.
