Currently, there are sophisticated applications that make it possible to visualize medical images and even to manipulate them. These software applications are of great interest, both from a teaching and a radiological perspective. In addition, some of these applications are known as Free Open Source Software because they are free and the source code is freely available, and therefore it can be easily obtained even on personal computers. Two examples of free open source software are Osirix Lite® and 3D Slicer®...

BACKGROUND: Scapular fractures have been traditionally taught to be associated with significant injuries and major morbidity. As we demonstrated with sternal fracture, pulmonary contusion and rib fracture, increased chest CT utilization and head-to-pelvis CT (pan-scan) protocols in blunt trauma evaluation, however, may diagnose minor, clinically irrelevant scapular fractures, possibly rendering previous teachings obsolete. OBJECTIVES: To determine the 1) percentages of scapular fractures seen on chest CT only (SOCTO) versus seen on both CXR and CT and of isolated scapular fracture (scapular fracture without other thoracic injuries), 2) frequencies of associated thoracic injury with scapular fracture, and 3) proportion of patients admitted, mortality, hospital length of stay, and injury severity scores (ISS), comparing four patient groups: scapular fracture, non-scapular fracture, scapular fracture SOCTO, and isolated scapular fracture...

Point-of-care ultrasound (POCUS) is rapidly emerging as a bedside diagnostic tool that can enhance physical diagnosis and facilitate clinical decision making. Although ultrasound is widely used by nephrologists for vascular access and kidney imaging, diagnostic POCUS skills in other anatomic areas are not part of routine nephrology training. In this narrative review, we will provide an overview of selected POCUS techniques, highlight potential uses of POCUS in routine nephrology practice, and describe a new curriculum implemented at Johns Hopkins University School of Medicine to teach diagnostic POCUS skills to nephrology fellows...

Nursing students and nurses often struggle with understanding pathophysiology concepts. Seventy-five students participated in two phases of an exploratory study that evaluated knowledge of pathophysiology concepts when taught using an innovation known as "visual narrative illustrations" (VNIs). Students taught using VNIs performed significantly better on a knowledge posttest and commented that the VNI humor and visual images helped them learn complex concepts. Used in combination with other teaching strategies, VNIs enhanced knowledge and understanding of pathophysiology concepts...
