Observational Study
Physiologic Effects of a New-Generation Conducted Electrical Weapon on Human Volunteers.
Conducted electrical weapons (CEWs) are used by law enforcement to restrain or repel potentially violent persons. The TASER X2 CEW is a next-generation device with new technology, including new electrical waveform and output specifications. It has not previously been studied in humans. ⋯ There was no evidence of dangerous physiology found in the measured parameters. The physiologic effects of the X2 CEW are similar to older-generation CEWs. We encourage further study to validate these results.

Delayed aortic injuries are a rare, but well-recognized complication of spinal surgery. They are a result of slow erosion of osteosynthesis material into the aorta. Although this is a life-threatening complication, patients might present years later with nonspecific symptoms. ⋯ The close proximity of the aorta and spine entertains the risk of aortic injury associated with vertebral osteosynthesis. Long-term complications of slow aortic erosion are extremely difficult to diagnose. The presented patient suffered from an undetected bronchio-aortic fistula with consecutive pseudoaneurysm formation and rupture. Awareness of slow aortic erosion is important for correct diagnostic pathways and subsequent early diagnosis to ensure a positive outcome for the patient.
