Evaluation of the porcine model to teach various ancillary procedures to gynecologic oncology fellows.

Objective: The purpose of this study was to subjectively evaluate the adequacy of the porcine model for training gynecologic oncology fellows.

Study Design: Following a defined surgical curriculum, fellow-attending pairs operated on female hogs. A predetermined dataset was collected for each procedure.

Blood rheological characterization using the thickness-shear mode resonator.

Thickness-shear mode (TSM) resonators have been used to characterize static rheological properties of plasma and whole blood samples. We demonstrated simple and rapid techniques for determining plasma viscosity without cell separation, for measuring erythrocyte sedimentation rate, and for tracking blood coagulation throughout the entire process. Additionally, mathematical models, previously developed to characterize surface-loaded resonators, were used to extract non-Newtonian and viscoelastic material properties of blood layers during sedimentation and coagulation experiments.

Stability of tuberosity reattachment in proximal humeral hemiarthroplasty.

Hemiarthroplasty can be an effective treatment for 4-part fractures of the proximal humerus; however, results are often unpredictable. Proper surgical technique is critical for success. Reconstruction of the displaced tuberosities should attempt to impart maximal interfragmentary stability.
