Improved markers of resuscitation are needed in patients with severe burn injuries. In previous animal and human work, we showed 1) wound hypoperfusion plays a role in burn depth progression, 2) that there are periods of repetitive ischemia and reperfusion which correlate closely to wound hypoperfusion, and 3) that wound ...

Despite almost 50 years of research on the functional morphology and biomechanics of suction feeding, no consensus has emerged on how to characterize suction-feeding performance, or its morphological basis. We argue that this lack of unity in the literature is due to an unusually indirect and complex linkage between the ...

Acute limb compartment syndrome (LCS) is a limb-threatening and occasionally life-threatening condition caused by bleeding or edema in a closed muscle compartment surrounded by fascia and bone, which leads to muscle and nerve ischemia. Well-known causative factors are acute trauma and reperfusion after treatment for acute arterial obstruction. Untreated compartment ...

Cement restrictors rely on achieving an interference fit with the wall of the medullary canal. Depending on the design of the cement restrictor, the intramedullary fit may be compromised as the femur starts to widen distally. Three different designs of cement restrictor were identified; universal, press-fit, and expandable. We determined ...

Complex pilonidal disease, an uncommon manifestation of an anorectal condition, is characterized by chronic or recurrent abscesses with extensive, branching sinus tracts. Definitive treatment requires wide excision of all involved tissue followed by secondary intention healing or reconstructive surgery. All treatment options have unique advantages and disadvantages. Following recent reports ...
