Marine envenomations can cause a diverse array of clinical syndromes. Systemic and life-threatening reactions, as well as delayed presentations, can occur. The pediatric population is at higher risk for serious reactions to envenomations because their greater body surface area and smaller body mass can lead to a higher relative venom load. Although the majority of the literature on marine envenomations is of low quality, the available literature does suggest that management varies depending on the geographic location. This issue reviews both common and life-threatening presentations of marine envenomations, highlights key aspects of the history and physical examination that will help narrow the differential, and offers recommendations for management based on the envenomating creature and geographic location.

A Retrospective Data Analysis on Marine Animal Injuries at a Large, Multi-Site Medical System.
HCA Healthc J Med
December 2024
Grand Strand Medical Center, Myrtle Beach, SC.
Background: With increasing numbers of human-animal interactions, there has been an increase in animal-related injuries. While canine bites are the most commonly reported animal injury, little data exists in regard to the other classes of animals, particularly marine life. The last comprehensive report on injuries related to noncanine bites and stings seen in emergency departments (EDs) across the US was between 2011 and 2015.

Background: Snakebite envenoming is a critical medical emergency and significant global public health issue, with India experiencing the highest annual snakebite deaths. Sea snakes in the Indian Ocean pose a severe threat to rural fishermen due to their potent neurotoxins.
Methods: From December 2020 to December 2021, we conducted surveys at 15 fishing ports in East Medinipur, West Bengal, and Balasore, Odisha, India (between 21.
Integrative multi-omics analysis reveals the contribution of neoVTX genes to venom diversity of Synanceia verrucosa.

Background: Animal venom systems are considered as valuable model for investigating the molecular mechanisms underlying phenotypic evolution. Stonefish are the most venomous and dangerous fish because of severe human envenomation and occasionally fatalities, whereas the genomic background of their venom has not been fully explored compared with that in other venomous animals.
Results: In this study, we followed modern venomic pipelines to decode the Synanceia verrucosa venom components.
Stingray Injury Complicated by Vibrio alginolyticus Wound Infection and Posterior Tibial Artery Pseudoaneurysm in a Returning Traveler.

Stingray injury is common in temperate and tropical waters worldwide. The majority of injuries are minor and can be managed with simple first aid at the shoreline; however, serious complications can occur. We report a case of Vibrio alginolyticus wound infection, retained foreign body, and posterior tibial artery pseudoaneurysm after stingray envenomation in a returning traveler.

Article Synopsis
- The study investigates the occurrence of freshwater jellyfish, specifically Craspedacusta sowerbii, in Misiones, Argentina, and its potential to cause envenomation in humans.
- It documents cases of skin lesions that coincided with the jellyfish's presence and analyzes its toxicological properties, revealing the presence of harmful enzymes and toxins.
- This research not only confirms the jellyfish's presence in northeastern Argentina but also aids health professionals in diagnosing and managing jellyfish-related injuries.
