Integrating Specialty-Specific Clinical Anatomy Education into the Post-Clerkship Curriculum.

Anatomy is a foundational science mainstay of undergraduate medical school education, particularly in the pre-clerkship curriculum. During the post-clerkship curriculum, students closer to graduate medical education may benefit from a focused concentration on human anatomy related to their specific clinical interests. Here, we describe a course for post-clerkship students that uniquely incorporates a multimodal approach of dissection, didactics, and clinical correlation to radiologic imaging, with the opportunity to personalize student learning on a specialty-specific anatomic region. The course increased students' confidence of anatomical knowledge and its clinical relevance. Other institutions may benefit from establishing a similar multimodal integrated post-clerkship anatomy curriculum.

Permanent refractive-index modification in germanium-doped optical fibers by use of red light.

We observed photoinduced birefringence in elliptical-core optical fibers by using a continuous-wave krypton-ion laser. We induced the birefringence by injecting 20 mW of 647-nm or 50 mW of 676-nm light into the fiber at 45 degrees to the slow axis. The rate of change of the refractive index was found to be proportional to the square of the average power. Polarization mode couplers written into the fibers have been stable for more than 2 years and can be erased by use of light polarized perpendicularly to the original writing beam.
