Active learning strategies enhance medical education by fostering self-directed learning, communication, and problem-solving skills. The paper puzzle, a game-based learning approach, provides an engaging way to reinforce anatomical knowledge and promote collaboration. This study assessed its impact on student performance and perceptions in clinical anatomy, comparing it to PowerPoint-based imaging reviews and evaluating the role of Near Peer Teachers (NPTs).

Situs inversus (SI) is a rare congenital disorder in which the abdominal and thoracic organs create a mirror image orientation of their typical anatomical positions. In this article, we present the case of a 49-year-old female individual who underwent a scheduled laparoscopic cholecystectomy (LC) due to postprandial colic pain in the epigastrium. A prior ultrasound examination, conducted a year earlier, revealed the presence of small gallstones within the gallbladder, and a follow-up preoperative ultrasound suggested the possibility of SI, though the diagnosis was ruled out by a third ultrasound.

Gallbladder disease is a frequent indication for non-obstetric surgical intervention during pregnancy. Gallbladder perforation (GBP) during pregnancy is an uncommon but severe pathology that usually requires immediate attention, and it represents a challenge for surgeons. We present the case of a GBP in a pregnant patient alongside a discussion of available surgical approaches.

Article Synopsis
  • Umbilical hernias (UHs) are often overlooked because they don't show symptoms, and a study aimed to find how common they are using CT scans in a trauma center.
  • A total of 472 CT scans were analyzed, revealing a high prevalence of 67.6% for UHs, particularly in men, while many cases (63.6%) were unreported by radiologists.
  • The study concluded that CT scans are a reliable method for diagnosing UHs, showing significant underreporting and varied sizes of the hernias in patients.

The diameter (mPAD) of the main pulmonary artery (pulmonary artery trunk) is a crucial indicator for cardiovascular health and prognoses in various conditions. Its enlargement is associated with increased mortality and severity in COVID-19-related pneumonia. However, its relevance to non-COVID pneumonia remains uncertain.

Inguinal hernias are the most common type of hernias in the groin, affecting 27% of the population, with a nine to 12 times higher incidence in men. The primary treatment for this condition typically involves a surgical procedure, with most surgeons opting for mesh placement through a laparoscopic approach. While this procedure is generally associated with low complication rates (primarily hematomas, seromas, and scrotal edema), there are some highly infrequent complications reported such as postoperative small bowel obstruction (SBO), estimated to occur in approximately 0.

Purpose: Umbilical hernias (UH) have a higher prevalence than previously considered. With the high workload radiologists must endure, UH can be missed when interpreting a computed tomography scan (CT). The clinical implications of its misdiagnosis are yet to be determined.

Introduction: Radiotracer Ga-PSMA-11 used in PET/CT scans allows for identification and localization of gland tissue. It allows for their consideration in clinical scenarios and to design further and stronger research to answer pertinent questions regarding their function and implications. We aimed to externally validate first reported findings of location, size, and ligand uptake of the tubarial glands using Ga-PSMA-11 PET/CT.

Background: The morbidity and mortality of intracranial aneurysm rupture motivate the risk evaluation of the patient´s characteristics and aneurysm's morphology. Brain vessel variants lead to hemodynamic changes that could increase risk. This study aims to evaluate the fetal posterior cerebral artery (fPCA) as a risk factor for the formation, rupture, and recurrence of the posterior communicating artery (PComA) aneurysm.
