Plasma free hemoglobin: a novel diagnostic test for assessment of the depth of burn injury.
Accurate determination of the depth of burn injury is difficult, even for experienced surgeons. The authors hypothesized that the level of plasma free hemoglobin following burn injury is correlated to the depth of burn injury, and they evaluated this hypothesis in a murine model. ⋯ The authors' data suggest that the level of plasma free hemoglobin after burn injury is related to the size and depth of burn injury. This test can potentially be a valuable diagnostic adjunct in the assessment of burns.

After studying this article, the participant should be able to: 1. Discern the importance of the physician's office administrative capacity. 2. Recognize the necessity of a system for quality assessment. 3. Assess which procedures are safe in the office-based setting. 4. Know the basic steps to properly evaluate patients for office-based plastic surgery. ⋯ Patient safety must be every physician's highest priority, as reflected in the Hippocratic Oath: primum non nocere ("first, do no harm"). In the office setting, this priority requires both administrative and clinical emphasis. The physician who gives the healing touch of quality care must always have patient safety as the foremost priority.

Lower extremity trauma: trends in the management of soft-tissue reconstruction of open tibia-fibula fractures.
Open lower leg fractures with exposed bone or tendon continue to be challenging for plastic surgeons. Microvascular free-tissue transfer increases the ability to close wounds, transfer vascularized bone, and prevent amputation, yet remains a complex, invasive procedure with significant complication rates, donor-site morbidity, and failure rates. This review documents the changing treatment protocol in the authors' institution for these injuries. ⋯ These results demonstrate a change in practice, with a trend down the reconstructive ladder, currently using fewer free flaps and more delayed closures and skin grafts with frequent use of the vacuum-assisted closure sponge. Possible reasons for this change are a better understanding of lower leg vascular anatomy and better use of improved wound care technology.

Regenerating axons emerge far proximal to the coaptation site in end-to-side nerve coaptation without a perineurial window using a T-shaped chamber.
Considerable controversy exists concerning the mechanism of axonal regeneration in end-to-side neurorrhaphy. The authors studied the mode of axonal regeneration in end-to-side neurorrhaphy without a perineurial window using a rat sciatic nerve model. ⋯ The authors could not locate the site of axonal sprouting in end-to-side neurorrhaphy without a perineurial window; however, this study cast doubts on current hypothesis on the mode of axonal regeneration in end-to-side neurorrhaphy.
