Abstract
Okinawa prefecture is a popular tourist destination due to its beaches and reefs. The reefs host a large variety of animals, including a number of venomous species. Because of the popularity of the reefs and marine activities, people are frequently in close contact with dangerous venomous species and, thus, are exposed to potential envenomation. Commonly encountered venomous animals throughout Okinawa include the invertebrate cone snail, sea urchin, crown-of-thorns starfish, blue-ringed octopus, box jellyfish, and fire coral. The vertebrates include the stonefish, lionfish, sea snake, and moray eel. Treatment for marine envenomation can involve first aid, hot water immersion, antivenom, supportive care, regional anesthesia, and pharmaceutical administration. Information on venomous animals, their toxins, and treatment should be well understood by prehospital care providers and physicians practicing in the prefecture.

Emergency Management Strategies and Antimicrobial Considerations for Nonmammalian Marine Vertebrate Penetrating Trauma in North America, the Caribbean, and Hawaii: A Review Article. Wilderness Environ Med 2023; 34:106-112. [PMID: 36610916 DOI: 10.1016/j.wem.2022.09.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 08/06/2022] [Accepted: 09/16/2022] [Indexed: 01/06/2023]
Abstract
There are numerous emergency department visits in the United States for all types of marine animal injuries each year. These injuries may result in significant morbidity or mortality if not managed appropriately. Accurate identification of the offending species, thorough wound hygiene, and judicious use of antibiotics are important for preventing infections. This review aims to describe management strategies and antimicrobial considerations for nonmammalian marine vertebrate penetrating trauma in North America, the Caribbean, and Hawaii. A literature search was performed to identify studies on this subject. This literature consisted of clinical case reports and case series. Reports extracted included those on sharks, barracuda, eels, catfish, stingrays, lionfish, stonefish, and scorpionfish. The majority of reported trauma occurred to beachgoers, fishermen, or commercial aquarium employees who routinely handle these animals. Injury patterns depended on the species but most commonly affected the lower extremities. Infections were seen from saltwater bacteria, human skin flora, or marine animal oral flora. After thorough wound irrigation and exploration, most authors recommended prophylactic antimicrobials to cover Vibrio species, in addition to other gram-negative and gram-positive species. The literature is notable for the lack of controlled studies. Some authors recommended radiographic and/or ultrasonographic imaging to identify retained foreign bodies, such as spines, sand, or teeth.

Abstract
BACKGROUND Across the world, many species of nondomesticated animals dwell among humans in metropolitan areas. Rare animal bites pose a dilemma for hand surgeons, as they often result in operative injuries and recalcitrant infections. The authors treated an 85-year-old man who experienced severe cellulitis of the index finger following an opossum bite. This case prompted a systematic review of upper extremity injuries caused by species other than dogs, cats, snakes, and insects. METHODS The authors conducted a systematic review of PubMed and Scopus databases to identify relevant articles published between 1980 and 2016. Two reviewers critically appraised the studies that met inclusion and exclusion criteria. RESULTS The hand infection in the man who sustained an opossum bite at the authors' institution was successfully treated with targeted antibiotic therapy, hand elevation, and splinting. Seventy-one articles met inclusion criteria for and were included in this systematic review. The vast majority of existing articles represent level IV and level V evidence. The relevant literature suggests that the majority of hand infections attributable to animal bites and stings are polymicrobial. CONCLUSIONS Injuries secondary to aquatic animals appear to be the most frequently described in the literature, and hot water immersion should be used for the majority of envenomation attributable to aquatic species. Infections can often be treated with an aminopenicillin antibiotic combined with a beta-lactamase inhibitor. Given the variability in presentation and potential for sequelae such as soft-tissue necrosis and systemic reactions, hand surgeons should approach such upper extremity injuries with a high degree of caution.

Abstract
Proteases play an important role in the field of tissue dissociation combined with regenerative medicine. During the years new sources of proteolytic enzymes have been studied including proteases from different marine organisms both eukaryotic and prokaryotic. Herein we have purified a secreted component of an isolate of Vibrio parahaemolyticus, with electrophoretic mobilities corresponding to 36 kDa, belonging to the serine proteases family. Sequencing of the N-terminus enabled the in silico identification of the whole primary structure consisting of 345 amino acid residues with a calculated molecular mass of 37.4 KDa. The purified enzyme, named VpSP37, contains a Serine protease domain between residues 35 and 276 and a canonical Trypsin/Chimotrypsin 3D structure. Functional assays were performed to evaluate protease activity of purified enzyme. Additionally the performance of VpSP37 was evaluated in tissue dissociations experiments and the use of such enzyme as a component of enzyme blend for tissue dissociation procedures is strongly recommended.

Abstract
Human and animal bites may lead to serious infection. The organisms involved tend to originate from the oral cavity of the offending biter, as well as the environment where the injury occurred. A variety of aerobic as well as anaerobic organisms have been isolated from bite wounds, with infection ranging from localized cellulitis to systemic dissemination, leading to severe disease ranging from abscess to bone and joint infection, to endocarditis and brain abscess. Immediate wound management, including recognition of the most commonly associated infectious pathogens, and judicious use of empiric antibiotics are crucial in providing the best care after a bite. Here, we discuss the common animal bite associated infections, and provide the most up to date information regarding their management.

Abstract
Serious infections can result from wounds that are caused by bites from animals and humans. Organisms recovered from bite wounds generally originate from the oral cavity of the biting animal, as well as from the patient's skin flora. Anaerobes have been isolated from animal and human bite wound infections, especially those associated with abscess formation. In addition to local wound infections, common complications, such as lymphangitis, septic arthritis, tenosynovitis, and osteomyelitis, and uncommon complications, such as endocarditis, meningitis, brain abscess, and sepsis, may occur. Wound management includes proper local care and, when needed, antimicrobial therapy.

Abstract
Wounds sustained in oceans, lakes, and streams are exposed to a milieu of bacteria rarely encountered in typical land-based injuries. These include Vibrio species, Aeromonas hydrophila, Pseudomonas and Plesiomonas species, Erysipelothrix rhusiopathiae, Mycobacterium marinum, and other microbes. Failure to recognize and treat these less common pathogens in a timely manner may result in significant morbidity or death. Initial antibiotic therapy should address common gram-positive and gram-negative aquatic bacteria, depending on the environment. Trauma occurring in brackish or salt water should be treated with doxycycline and ceftazidime, or a fluoroquinolone (eg, ciprofloxacin or levofloxacin). Freshwater wounds should be managed with ciprofloxacin, levofloxacin, or a third- or fourth-generation cephalosporin (eg, ceftazidime). Injuries sustained in a marine or freshwater environment may result from bites or venomous stings of aquatic organisms as well as from accidental trauma. Musculoskeletal trauma caused by venomous underwater species (eg, stingrays, stinging fish, sea urchins, and coral) requires immediate neutralization of the heat-labile toxin with immersion in nonscalding water for 30 to 90 minutes. Appropriate management of aquatic wounds requires recognition of the mechanism of injury, neutralization of venom, antibiotic administration, radiographic assessment, surgical débridement with irrigation, wound cultures, and structural repair or amputation as indicated by the severity of the injury.

Abstract
This article describes the microbiology, diagnosis, and management of human and animal bite wound infections. Various organisms can be recovered from bite wounds that generally result from aerobic and anaerobic microbial flora of the oral cavity of the biting animal, rather than the victim's own skin flora. The role of anaerobes in bite wound infections has been increasingly appreciated. Anaerobes were isolated from more than two thirds of human and animal bite wound infections, especially those associated with abscess formation. This article describes several of the organisms found in the bites of various species. In addition to local wound infection, other complications may occur, including lymphangitis, local abscess, septic arthritis, tenosynovitis, and osteomyelitis. Rare complications include endocarditis, meningitis, brain abscess, and sepsis with disseminated intravascular coagulation, especially in immunocompromised individuals. Wound management includes the administration of proper local care and the use of proper antimicrobial agents when needed.
