  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...

Asiopisinus gen. nov., a new genus of the family Theridiidae Sundevall, 1833 (Araneae, Theridiidae) from eastern Asia

Abstract

Based on morphological evidence and prior molecular phylogenetic results by Liu et al., a new genus, Asiopisinus gen. nov., is described from East Asia. The new genus comprises A. cheni sp. nov. (♂♀) as the type species, along with seven species transferred from Episinus Walckenaer, 1809: A. anfu (Liang, Liu, Yin & Yu, 2025) comb. nov., A. baoshanensis (Liu, Irfan & Peng, 2019) comb. nov., A. implicatus (Liang, Liu, Yin & Yu, 2025) comb. nov., A. nubilus (Yaginuma, 1960) comb. nov., A. ornithorhynchus (Liu, Agnarsson, Liu & Zhu, 2022) comb. nov., A. pseudonubilus (Liang, Liu, Yin & Yu, 2025) comb. nov., and A. yoshidai (Okuma, 1994) comb. nov.. The male of A. implicatus (Liang, Liu, Yin & Yu, 2025) comb. nov. is described for the first time. In addition, remarks and photos of some Chinese Episinus species are provided. The distribution records of all Asiopisinus gen. nov. species have been mapped.
