Vol. 38 No. 1 (2025)

The illustration that accompanies this first issue of volume 38 is inspired by the article “Characterization of executive functions and academic performance in medical students of the Corporación Universitaria Remington, 2021”, published in this edition.

Vol. 37 No. 4 (2024)

This illustration is an allegory for two articles published in this issue: "Limbic Encephalitis: A Narrative Review of the Literature" and "Opioids in Pediatric and Neonatal ICU: A Proposal for Their Discontinuation." This metaphor is represented by the Papaver somniferum L. plant, from which opioids are derived and used for pain management. The article included in this issue proposes a strategy for discontinuing these medications, and the center of the plant depicts the brain affected by limbic encephalitis, in reference to the manuscript "Limbic Encephalitis: A Narrative Review of the Literature."

Photograph Title: Membranous Glomerulonephritis

This photograph shows a glomerulus from a patient with membranous glomerulonephritis, displaying the characteristic spikes or projections of the basement membrane, stained with silver methenamine (original magnification 40X).

Morphologically, immune complexes deposit in the subepithelial capillary walls (outer face of the basement membrane), prompting a response from the membrane to try to encircle or surround them. In light microscopy, with silver methenamine staining, perpendicular projections can be observed on the basement membrane, consisting of material similar to it, known as spikes. These projections progressively extend and encircle or envelop the immune complexes. In tangential sections of the membrane, they appear as spaces or holes corresponding to the immune complex (an apparently empty space that does not stain with silver methenamine), completely surrounded by the basement membrane. These immune complexes, in some cases, can also be visualized by light microscopy with trichrome staining and, more specifically, by immunofluorescence.

Title of the photograph: Spontaneous Pneumoperitoneum Secondary to Intestinal Cystic Pneumatosis

Description: A 40-year-old woman with a history of systemic lupus erythematosus (SLE) for a year and a half, presenting to the emergency department with visceral abdominal pain of two weeks' duration. She underwent a contrast-enhanced abdominal computed tomography (CT) scan, which revealed gas accumulation in the greater omentum and subserosal layer of the small intestine and colon, as well as secondary pneumoperitoneum in the coronal plane (Figure A). Due to the worsening of her clinical condition, diagnostic and therapeutic laparoscopy was performed, documenting multiple thin-walled air-filled cysts (cystic pneumatosis) in the colon and small intestine, without perforation of hollow viscera (Figure B). Finally, conservative medical management with parenteral steroid pulses was chosen, leading to an acceptable medical response over time, without additional surgical interventions.

Photograph Title: "Diafanización" (Diafanization)

Description: A preserved fish and snake using diafanization, a technique that involves depigmenting soft tissues and pigmentation of mineralized tissues to visualize the bony and cartilaginous components of the organism being studied. This and other preserved animals can be found in the morphology building of the Faculty of Medicine at the University of Antioquia.

Título de la fotografía: Morfogénesis del virus de la viruela de mono

Descripción: composición que muestra las etapas de formación del virus de la viruela del mono (Monkeypox virus) en células de riñón de mono (VERO-E6). Las células infectadas fueron fijadas con glutaraldehído al 2,5 % y tetróxido de osmio al 1,2 %, se incluyeron en resina epóxica y se hicieron cortes de 60 a 90 nanómetros; los cortes se contrastaron con acetato de uranilo y citrato de plomo y se visualizaron en un microscopio electrónico de transmisión con un aumento de 1.000.000 X. A. Dos semilunas que constituyen la etapa inicial de la formación del virus. B. Viriones inmaduros (óvalos claros) y algunos en un estado más avanzado de formación (óvalos oscuros). C. Varios viriones maduros cerca a la membrana celular y un virión en el momento de salir de la célula. D. Virión maduro fuera de la célula; en este se pueden observar algunos detalles como la membrana de superficie (flecha corta), el core o nucleoide (flecha larga) y los cuerpos laterales (cabezas de flecha).
