Post-traumatic phenomena secondary to snakebite envenomation: a psychiatric clinical perspective

  Post-traumatic phenomena secondary to snakebite envenomation: a psychiatric clinical perspective Abstract Snakebite envenomation represents a major global public health concern. Beyond physical outcomes suffered by the patients, studies have documented significant psychiatric and psychological sequelae. Consequently, there is an urgent need to document and intervene the psychiatric/psychological sequelae of snakebite envenomation alongside the clinical assessment. This work presents a narrative review of the psychiatric consequences described in snakebites in several settings. In addition, it addresses the screening/detection actions focused on Post-Traumatic Phenomena from a psychiatric perspective that are useful in general and specialized medicine settings in snakebite envenomation.

When the predator becomes the prey: new records of intraguild predation among Central American and Caribbean arachnids (Arachnida: Amblypygi, Araneae, Scorpiones)


ABSTRACT


Intraguild predation occurs when an organism preys on a competitor. This ecological interaction can have considerable consequences on the population dynamics of predators and indirectly affect their prey. In arachnids, it is a quite common phenomenon, but it has been poorly documented in the Neotropical region. Here, we present records of 16 species feeding on other 14 species of arachnids. The most common families that acted as predators were Buthidae (Scorpiones) and Salticidae (Araneae), while the most common prey were members of the families Araneidae and Ctenidae (Araneae). In our survey, Drake Bay, in Costa Rica, is overrepresented due to years of systematic observations by two of the coauthors.
