The effect of proximal tibial fractures on the limb axis in children.

Between 1985 and 2002 we treated 38 children with 39 fractures of the proximal tibia. Fractures affecting the proximal tibial physis were excluded from this study. Mean age at the time of injury was 7.

Retroperitoneal compartment pressure elevation impairs pancreatic tissue blood flow.

Objectives: To investigate whether the increase of the retroperitoneal compartment pressure, as in the case of peripancreatic fluid accumulation in severe acute pancreatitis, simulated by infusing a colloid fluid into the retroperitoneum, has any effect on pancreatic tissue blood flow.

Methods: Six male anesthetized swine were subjected to a transcutaneous placement of catheters into the retroperitoneal space. Through these catheters, a colloid solution was infused, under continuous retroperitoneal pressure monitoring, to achieve a pressure up to 20 mm Hg.
