To evaluate the outcome and highlight the operative tips of using the reverse posterior interosseous artery (PIA) flap in the treatment of severe contractures of the first web space. ⋯ The reverse PIA flap is suited for defect cover in the treatment of severe contractures of the first web space. A usual pitfall using the reverse PIA flap is that the skin paddle is inadvertently outlined over the proximal 1 of 3 forearm to increase its distal reach, which usually leads to postoperative venous congestion. However, if the distal flap pole is placed at or distal to the midpoint from the lateral epicondyle to the radial side of the ulnar head, choosing the proximal 1 of 2 forearm as the donor site of the skin paddle to increase its distal reach is reliable.

Induced hypothermia after cardiac arrest is an accepted neuroprotective strategy. However, its role in cardiac arrest during acute trauma care is not yet defined. To characterize recent experience with this technique at our center, we undertook a detailed chart review of acute trauma patients managed with induced hypothermia after cardiac arrest. ⋯ Mild induced hypothermia can be beneficial in a selected group of trauma patients after cardiac arrest. Prospective trials are needed to explore the effects of targeted temperature management on coagulation in this patient group.

The aim of this study was to evaluate the role of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and its quantitative coefficient (K(trans)) in the assessment of the extent of traumatic brain injury (TBI) in a rabbit model. ⋯ DCE-MRI and its quantitative coefficient, K(trans), have the potential to accurately assess the blood-brain barrier and the extent of injury in an in vivo model of TBI.

Comparative Study
Variations in bone mineral density of proximal femora of elderly people with hip fractures: a case-control analysis.
Bone mass as represented by bone mineral density (BMD) is the most important factor determining bone strength. Elderly people with and without hip fractures were compared with the BMD of the proximal femora. The correlation between hip fractures in elderly patients and osteoporosis was investigated. ⋯ The severity of osteoporosis may affect the risk of hip fractures in elderly people. The risk of intertrochanteric fractures may be determined simply by BMD, but the risk of femoral neck fractures may be determined by multiple factors. Intertrochanteric fractures may start at the greater trochanter due to its low BMD.
