Abstract: This study describes a cohort of foreign medical school graduates (FMGs) who first sat for the American Board of Internal Medicine's (ABIM) 1982 certifying examination, compares their performance with that of US medical school graduates, describes differences between US citizen FMGs and alien FMGs, and examines which background factors predict success on the ABIM examination. Data for this study were derived by combining information retained by the Educational Commission for Foreign Medical Graduates with ABIM data. Most FMGs who took the 1982 ABIM certifying examination for the first time were educated in and citizens of Asia, but a sizable minority were US citizens educated in Europe. Scores and program directors' ratings were lower for FMGs than US medical school graduates, and they attended different types of training programs. United States citizen FMGs were very similar to alien FMGs. Foreign medical school graduates who did well on the ABIM examination had done well on the Educational Commission for Foreign Medical Graduates examination and were rated highly by their residency program director.

Abstract: The ultimate cause of destruction of red blood cells (RBCs) after oxidative damage with Heinz body formation is not well understood. We correlated the changes in RBC morphology and membrane protein composition after oxidant treatment with the alterations in deformability of whole cells and cell membranes. The incubation of RBCs with phenylhydrazine concentrations of 0.3 to 100 mg/dL at 37 degrees C for one hour led to a dose-dependent formation of Heinz bodies, ranging from isolated Heinz bodies at 1 mg/dL to a confluent coating of the inner membrane surface at 100 mg/dL phenylhydrazine. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis revealed the presence of a large quantity of hemoglobin bound to the ghost membrane of treated RBCs. Electrophoresis with and without dithiothreitol indicated that disulfide bridges are abundant between hemoglobin molecules and are also present among membrane proteins but are not the major bond between hemoglobin and membrane. Changes of spectrin, ankyrin, band 3, and band 6 and the appearance of a 260,000-dalton complex were also observed. With phenylhydrazine concentrations below 30 mg/dL, even in the presence of multiple Heinz bodies, the RBC deformability measured by filtration through 2.6-, 4.5-, and 6.8-microns pores and the membrane deformability determined by a filter aspiration technique were not altered. With 100 mg/dL phenylhydrazine, when the entire membrane was coated with Heinz bodies, RBC filterability and membrane deformability were drastically reduced. These results indicate that oxidative damage of RBCs with discrete Heinz body formation causes focal membrane rigidification but does not affect the global cellular deformability until the Heinz bodies nearly cover the entire cell endoface.

Abstract: In reconstructing the anterior cruciate ligament (ACL) it is important to place the inner ends of the drill channels correctly, to get the ACL into an isometric position. Anatomic studies demonstrate the value of a modified surgical technique using a special drill guide for standardized positioning of the anterior cruciate substitute. The drill guide consists of a metal frame with one adjustable and one fixed guide tube. Drilling is done from the anteromedial aspect of the tibia, upwards, through the joint space and the femur in a straight line, both channels being drilled in a single procedure. The precision of guided drilling was superior to that of free-hand drilling in positioning the ligament in the correct anatomic place.
