Migration of trochanteric cerclage cable debris to the knee joint.

Migrating orthopedic hardware has widely been reported in the literature. Most reported cases of migrating hardware involve smooth Kirschner wires or loosening/fracture of hardware involved with joint stabilization/fixation. It is unusual for hardware to migrate within the soft tissues.

Update on talar fracture patterns: a large level I trauma center study.

Objective: Prior studies of talar fracture patterns are dated and based on radiography only. The purpose of our study was to describe talar fracture patterns and associated injuries in a modern large level 1 trauma center setting using both radiography and CT.

Materials And Methods: The radiolog and clinical data of patients with acute talar fractures diagnosed over an 18-month period were retrospectively reviewed.

Quality initiative: Quantifying and reducing dose in multiphase liver CT: Eliminating the nonenhanced study and using conscientious Z-creep.

The use of computed tomography (CT) for evaluation of liver disease has increased dramatically at our tertiary care center due to increased hepatology referrals. We sought to decrease the radiation dose associated with multiphase liver CT studies while maintaining a high degree of diagnostic accuracy. We found that by eliminating the nonenhanced acquisition and adjusting the imaging field of view to include the liver-containing abdomen only-simply by manipulation of patient-specific imaging parameters-we achieved a 30% reduction in dose.

Expanded polytetrafluoroethylene-covered stent treatment of angioplasty-related extravasation during hemodialysis access intervention: technical and 180-day patency.

Purpose: To review technical and patency results with expanded polytetrafluoroethylene (ePTFE)-covered stents for treatment of venous rupture encountered during percutaneous hemodialysis intervention.

Materials And Methods: The Fluency covered stent is a tracheobronchial device that was used in an off-label manner to treat percutaneous transluminal angioplasty (PTA)-induced rupture in hemodialysis circuits. Data were retrospectively reviewed for all patients treated with the stent in 2004-2005 at two medical centers for PTA-related rupture.

Pretraining on Southwestern stations decreases training time and cost for proficiency-based fundamentals of laparoscopic surgery training.

Background: We previously reported a proficiency-based Fundamentals of Laparoscopic Surgery (FLS) curriculum that uniformly resulted in passing the technical skills certification criteria. We hypothesized that pretraining using the Southwestern (SW) videotrainer stations would decrease costs and training time and maintain benefits.

Study Design: Group I (2nd-year medical student, n = 10) underwent FLS pretesting (Pretest 1), SW station proficiency-based training, repeat FLS testing (Pretest 2), FLS proficiency-based training, and final FLS testing (Posttest).

Purified NPC1 protein. I. Binding of cholesterol and oxysterols to a 1278-amino acid membrane protein.

The Niemann-Pick, Type C1 protein (NPC1) is required for the transport of lipoprotein-derived cholesterol from lysosomes to endoplasmic reticulum. The 1278-amino acid, polytopic membrane protein has not been purified, and its mechanism of action is unknown. Unexpectedly, we encountered NPC1 in a search for a membrane protein that binds 25-hydroxycholesterol (25-HC) and other oxysterols.
