  A further new species for the genus Ananteris Thorell, 1891 (Scorpiones: Ananteridae) from a poorly prospected region of Brazilian Amazonia Abstract  A new species of the genus Ananteris Thorell, 1891 is described from the region which today defines the ‘Reserva Biológica do Río Trombetas’ in the state of Pará, Brazil. The collection of the unique specimen, presently study, took place previously to the definition of this reserve, in a joint field trip with a team of the Instituto Brasileiro de Desenvolvimento Florestal (IBDF). Ananteris antoni sp. n. is described based on one female specimen collected in a zone of dense humid forest, under death log. With this new description, the number of Ananteris species known for the scorpion fauna of Brazil is now raised to 33. Lourenço W.

Scorpion Sting: A Reason for Failed Local Anesthetic Action (CASE REPORT)

Posted by

 

Abstract

Failed action of local anesthetics can be due to technical errors, but resistance to local anesthetic agents can also be a reason. Scorpion venom has the potential to cause antibodies to local anesthetics and genetic mutations in the receptors resulting in local anesthesia resistance. We would like to report two cases with a history of scorpion stings in the past where resistance to local anesthetic agents was seen. Local anesthesia resistance can be manifested as inadequate block or block failure. In such cases, the anesthesiologist should keep a history of scorpion bite in mind in areas where scorpion sting is common. Eliciting the history of scorpion bites should be a part of the routine preoperative protocol in areas where scorpion bites are frequent.
