An adult male is captured mid-lecture in what appears to be a classroom or seminar room in Mexico City, Mexico. The individual, identified as "Dr. Jorge Fernando, Cirujano" (Surgeon) by the projected slide, is presenting on "APENDICITIS AGUDA" (Acute Appendicitis). He is an older male with graying dark hair and glasses, wearing a black and white vertical striped long-sleeved shirt, dark trousers, a braided dark belt with a silver-toned buckle, and a black bracelet on his left wrist. He stands angled to the viewer's right, gesturing with his raised left hand, palm open, and his mouth slightly ajar as if speaking. The presentation slide, featuring a magnified biological image, is projected onto a white surface in the background. In the foreground, white-topped tables with wooden trim and gray metal bases are partially visible on both sides of the speaker. The room's lower walls feature light-colored horizontal paneling, with the upper walls painted plain white.
