Hyperbaric oxygen induces endogenous neural stem cells to proliferate and differentiate in hypoxic-ischemic brain damage in neonatal rats.
Studies suggest that after brain injury, hyperbaric oxygen (HBO2) is neuroprotective by stimulating cell proliferation. We examine whether HBO2 promotes neural stem cells (NSC) to proliferate and differentiate in neonatal hypoxic-ischemic (HI) rats. ⋯ This study suggests that HBO2 treatment may promote neurogenesis of the endogenous NSC in neonatal HI rats, contributing to repair of the injured brain.

Case ReportsCT finding of VGE in the portal veins and IVC in a diver with abdominal pain: a case report.
The finding of abdominal venous gas emboli (VGE) on computerized tomography (CT) is reported for the first time in a recreational diver. The patient presented 2-3 hours after surfacing from two deep air dives and subsequently complained of visual blurring and abdominal pain. ⋯ The patient was treated for decompression sickness (DCS) with a US Navy Treatment Table 6 and achieved complete resolution of symptoms. The routine use of CT for venous bubble detection in symptomatic divers is not endorsed, but may provide objective evidence of VGE when DCS is in the differential diagnosis and corroborative evidence would alter management.

Practice GuidelineThe SANDHOG criteria and its validation for the diagnosis of DCS arising from bounce diving.
A three-point scale, the SANDHOG (SAN Diego Diving and Hyperbaric Organizations) criteria, was developed to diagnose DCS (decompression sickness), and then it was validated against a known database of diving related injuries. ⋯ The specificity of the SANDHOG criteria is good, and demonstrates that the SANDHOG criteria are a useful tool for the diagnosis of DCS.

While carbon monoxide (CO) poisoning is common in the USA, its incidence is uncertain. Fatal poisonings are counted with relative accuracy from death certificate data, but estimates of the more common nonfatal poisonings are either old or limited. This study was performed to estimate the number of emergency department (ED) visits annually in the USA for carbon monoxide poisoning. ⋯ There are approximately 50,000 ED visits for CO poisoning in the USA annually, 3-5 times the numbers previously estimated. As this disease can result in significant long-term morbidity even when treated, enhanced prevention efforts are warranted.

To describe the characteristics of severe pediatric CO poisoning cases treated with hyperbaric oxygen (HBO2) to determine key features that might aid prevention efforts. ⋯ Severe pediatric CO poisoning demonstrates a seasonal pattern with key sources of exposure varying by gender, age, and race/ethnicity. Minorities are at increased risk for severe CO poisoning. Intentional CO poisoning occurs primarily among adolescent males and by motor vehicle exhaust. Prevention efforts should take these factors into consideration.
