The lotus position--bilateral cross-thigh flaps for simultaneous coverage of both feet: case report.
A 6-year-old girl with an avulsion injury of the dorsum of both feet had multiple fractures of the ankles and the tarsal and metatarsal joints. She was treated by wet dressings followed by simultaneous coverage of both feet with bilateral cross-thigh flaps. 相似文献

Dogs with chronic biliary cirrhosis and portal hypertension commonly develop plasma volume expansion, urinary sodium retention, ascites, and perturbed systemic hemodynamics, i.e., a rise in cardiac output and a fall in peripheral vascular resistance. Our laboratory has previously demonstrated that creating a side-side portacaval anastomosis in such animals, and so venting hepatoportal pressure, will prevent sodium retention and ascites formation and will maintain the animals euvolemic. In the present study, in four cirrhotic dogs with such an anastomosis, observations made at 12 weeks postbiliary duct ligation, and in the presence of grossly disturbed liver function and morphology, failed to demonstrate any change from control conditions in arterial blood pressure, cardiac output, or peripheral vascular resistance. We conclude that venting hepatoportal pressure in cirrhotic dogs with markedly disturbed liver function prevents the advent of a hyperdynamic circulation, possibly by preventing volume expansion. 相似文献

Previous models of the renal concentrating mechanism employ ideal approximations of solution thermodynamics for membrane transport
calculation. In three-dimensional models of the renal medulla, predicted urine concentrations reach levels where there idealized
approximations begin to break down. In this paper we derive equations that govern membrane transport for non-dilute solutions
and use these equations in a three-dimensional model of the concentrating mechanism. New numerical methods were employed that
are more stable than those employed previously. Compared to ideal solution models, the urea non-ideality tends to increase
predicted osmolarities, whereas NaCl non-ideality decreases predictions. 相似文献
