  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...

Systematic study of the Ageniellini spider wasp genus Machaerothrix Haupt (Hymenoptera: Pompilidae) from Japan and Southeast Asia

ABSTRACT

A systematic study of Machaerothrix Haupt from Japan and Southeast Asia was conducted. The description of the genus is revised. The female and male of M. tsushimensis natsumiae subsp. n. from Honshu, Japan, the female of M. malaysiensis sp. n. from Malaysia, the male of M. tsushimensis tsushimensis Yasumatsu from Tsushima Is. Japan, and the female of M. quadridentata (Tsuneki) from the Philippines are described for the first time. The female of M. tsushimensis tsushimensis and the male of M. quadridentata are redescribed. A key to all the known species of the genus is presented. The distribution, nesting and social behaviour of the genus are discussed.
