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.

Despite the lack of evidence, traditional trauma teaching has suggested that low rib fractures increase the risk of abdominal solid organ injury (ASOI). This study was designed to assess if in fact this is true, and to try and define other factors that increased the risk of ASOI in rib fracture patients. ⋯ In hospitalized trauma patients, low rib fractures, right-sided rib fractures, female gender, young age, and an elevated ISS increased the probability of liver injury; and low rib fractures, left-sided only rib fractures, young age, and an elevated ISS increased the probability of splenic injury. Associated pelvic fractures and long bone fractures did not increase the likelihood of ASOI in this cohort.

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.
