High-pressure injection (HPI) injury of the hand is a serious injury that can be potentially devastating. There have been a number of publications on the results of its treatment, but we are not aware of a report on the functional outcome of these hands. ⋯ Deterioration of hand function is a predictable outcome of HPI injury. This information should be shared with the patient at the outset so as to avoid subsequent disappointment.

The purpose of this study was to use a prototype side-illuminating near-infrared spectroscopy (NIRS) nasogastric probe to continuously measure changes in gastric tissue oxygen saturation (Sto2) in a pig hemorrhage model. ⋯ Direct measurement of tissue oxygen saturation with a prototype side-illuminating near-infrared spectroscopy gastric probe appeared to rapidly reflect changes in splanchnic perfusion.

The present study investigates whether whole-body or local (chest) exposure to blast overpressure can induce ultrastructural, biochemical, and cognitive impairments in the brain. ⋯ These results confirm that exposure to blast overpressure induces ultrastructural and biochemical impairments in the brain hippocampus, with associated development of cognitive deficits.
