This objective

of this study was to examine the Crash Injury Research Engineering Network and to determine at what age motor vehicle crash fatalities from head injuries increased.

Methods: The Crash Injury Research Engineering Network database was queried from 1996 to 2009. Study inclusion criteria were adult vehicle occupants with TBI, with an Abbreviated Injury Scale score >= 2. The age at which mortality increased was calculated. Patients younger and older than this cutoff age were compared to determine differences in crash characteristics. The determined cutoff age was compared with one found in a larger, population-based database.

Results: There were 915 patients who met the study criteria. An increase in mortality was seen at age 60 years despite no difference in Injury Severity Score and a decrease in crash severity. Patients <= 60 years were more likely to have alcohol Smoothened Agonist involved, to be in a rollover crash, and had higher crash speeds. Comparing the element of the crash attributed to the head injury, the patients >60 years were more likely to have struck the airbag, door,

and seat. An analysis of the larger database revealed an increase in mortality at age 70 years.

Conclusions: There was a higher mortality Ferroptosis inhibitor secondary to head injuries in those older than 60 years involved in motor vehicle crashes. Improved safety measures in vehicle design may decrease the number of head injuries seen in the older population.”
“Photodynamic therapy (PDT) with 5-aminolevulinic acid (ALA) GSK461364 concentration (ALA-PDT)

using intense pulsed light (IPL) as a light source (IPL-ALA-PDT) has been used for photorejuvenation, but it is unclear if this protocol can be applied to darker skin types. We performed this study to assess our IPL-ALA-PDT protocol for photorejuvenation in Asian skin. To determine an appropriate dose, ALA ointment (0-20%) was applied to the upper arm of five healthy volunteers and the fluorescence intensity (FI) was measured using a spectrofluorometer. Non-linear regression analysis of FI 2 h after ALA application with global fitting gave a typical sigmoid dose-response curve with R(2) = 0.9705 and saturation after 5% ALA. The entire faces of 16 Japanese women with photodamage were then treated with IPL (500-670 and 870-1400 nm, 23-30 J/cm(2)) 2 h after application of 5% ALA to one side of the face. Three treatments were delivered at 4-week intervals with follow-up visits. Comparative analysis of photorejuvenation showed noticeable improvements on both sides of the face, although the reduction in the photoaging score from baseline did not differ significantly between the two sides in all subjects. Despite this finding, 75% of the patients felt that the IPL-ALA-PDT-treated side of the face showed greater improvement than the IPL-treated side.
