A method to prepare bone-implant specimens for laboratory analysis

Summary A method for the preparation of bone samples containing metallic implants is presented. Technics are detailed for samples to be analyzed by mechanical, microradiographical and microangio-graphical means, and by tetracycline labeled fluorescent and polarized light microscopy.     

Technique to prepare the bed for autologous bone grafting in nonunion surgery

This article describes a technique for preparing the bed for autologous bone grafting in nonunion surgery. The procedure is divided into 2 steps. First, both ends of the fracture fragments are chipped into small pieces using an osteotome and hammer without peeling off the periosteum, creating pathways into the bone marrow. Second, cancellous bone harvested from the iliac crest is grafted into the aperture created by the previous bone chipping treatment. The technique is easy to perform and is a promising approach for enhancing bone healing in nonunion and delayed union.     

A senior elective designed to prepare medical students for surgical residency

BACKGROUND: The transition from medical student to surgery internship can be stressful. The goal of this project was to design, implement, and evaluate a 1-month long elective course that would meet the majority of the American College of Surgeons Graduate Medical Education Committee prerequisites for graduate surgical education METHODS: The major elements of the curriculum included faculty- and resident-facilitated case-based sessions and cadaver dissections. In addition, the students participated in skills laboratory experiences, Intensive Care Unit rounds, and mock interviews and clinical pages. The students took a knowledge pretest and post-test that was compared with the performance of 8 surgical interns on the same examination. RESULTS: The highest rated elements of the course were those that provided hands-on experience or practical knowledge. The post-test knowledge examination scores were significantly higher than pretest scores and surgical intern scores. CONCLUSIONS: It was possible to develop a 1-month senior medical student elective course that provided students with the essential prerequisites believed to be essential for all surgical interns.     

Use of cyanoacrylate glue to prepare cultured keratinocyte sheets for grafting

We describe a method to prepare keratinocyte cultured sheets for grafting based on the use of an organic glue (n-butyl-2-cyanoacrylate). It is a rapid and easy method in which the cultured layers of keratinocytes remain with a surface area similar to the original cultures.     

陈琳：再见十二种颜色

那天，天寒地冻，行人都穿了厚厚的棉衣，我在高波工作室门口遇见她们。一辆笨重的吉普车，从里面依次跳出一个个鲜亮五彩的人，那是陈琳、中国辣妹和助手们。她们好似迎面的蝴蝶，带着十二种颜色的缭乱，一时间让人有些失措——我想说，无论谁在这个沉闷的冬天看见这幅风景，都会以为是春天破茧而来了。
