A 76-year-old woman reported a fishbone stuck in her throat, but no foreign body was identified. Eight weeks later, she experienced a transient ischaemic attack, and a stingray barb was subsequently removed from the right common carotid artery. To our knowledge, this is the first report of the migration of an ingested stingray barb.

Bioactive Properties of Venoms Isolated from Whiptail Stingrays and the Search for Molecular Mechanisms and Targets.
Pharmaceuticals (Basel)

The venom-containing barb attached to their 'whip-like' tail provides stingrays a defensive mechanism for evading predators such as sharks. From human encounters, dermal stingray envenomation is characterized by intense pain often followed by tissue necrosis occurring over several days to weeks. The bioactive components in stingray venoms (SRVs) and their molecular targets and mechanisms that mediate these complex responses are not well understood.

Article Synopsis
- Stingray envenomation is common in coastal emergency departments, and while radiographs are the standard for detecting retained stingray barbs, ultrasound may also be useful.
- A study involving 32 emergency medicine residents assessed their ability to use ultrasound to identify stingray barbs in pig and chicken tissue models after a brief training session.
- Results showed that residents had moderate success in detecting barbs with varying sensitivity and specificity, but experience level did not significantly impact their accuracy.

Article Synopsis
- * The report discusses a case involving a Pacific cownose ray injury, highlighting complications from a retained spine in the foot that led to infection and tissue necrosis.
- * It emphasizes the importance of diagnostic imaging, like soft tissue radiographs and MRI, to detect barbs and prevent complications, noting that current treatment methods rely on limited scientific studies and various case reports.
Management of a stingray barb laceration and suspect envenomation in a dog.

Pet Emergency, Queensland Veterinary Specialists, North Lakes, Australia.
This case report describes the successful management of a stingray laceration and suspected envenomation using a combination of opioid analgesia, heat compression, antimicrobial therapy, surgical debridement and closure. Stingray envenomation in the dog is a rare clinical presentation and is yet to be documented in the Australian veterinary literature. Envenomation can be markedly painful and may cause swelling and local tissue necrosis.
