The recent outbreak of indie games has popularized volumetric terrains to a new level, although video games have used them for decades. These terrains contain geological data, such as materials or cave systems. To improve the exploration experience and due to the large amount of data needed to construct volumetric terrains, industry uses procedural methods(More)
Rectal cancer metastatic to the breast is an exceedingly rare event with around 15 cases reported in the literature. A metastatic breast deposit from the rectum signifies diffuse disseminated disease or a highly aggressive tumor such that surgical intervention other than palliation has a limited role. In the present report, we discuss a patient who(More)
Accurate staging of rectal cancer is essential for selecting patients who can undergo sphincter-preserving surgery. It may also identify patients who could benefit from neoadjuvant therapy. Clinical staging is usually accomplished using a combination of physical examination, CT scanning, MRI and endoscopic ultrasound (EUS). Transrectal EUS is increasingly(More)
INTRODUCTION No Gut Syndrome refers to a condition which results after a near total enterectomy (NTE) has been performed. These patients are unable to sustain life without life-long parenteral nutrition (PN). Re-establishment of bowel continuity, complications, quality of life (QoL), and overall outcomes are important aspects to be considered in patients(More)
BACKGROUND The purpose of this study is to understand why learning goals and performance goals may produce different outcomes in surgical skills training for novices, with specific attention to metacognition and task engagement. METHODS Third-year medical students were randomized to a performance or learning-goal condition during a knot tying and suturing(More)
Digital papillary adenocarcinoma (DPA) is a rare malignant tumor of the sweat glands that often presents as a solitary painless mass on the digits of the hands or feet. We present a rare case of DPA on the ankle in a 54 year-old African American man. Although the most common location for digital papillary adenocarcinoma is on the hands and feet, it can(More)
—The volumetric approach for terrain representation is a technique used by several video-games and other graphic applications to manage both surface and geological data from the virtual world. To enhance the exploration experience and due to the amount of data required by this approach, volumetric terrains are usually generated with procedural methods.(More)
