Purpose: Structured abdominal examination is an essential part of the medical curriculum and surgical training, requiring a blend of theory and practice from trainees. Current training methods, however, often do not provide adequate engagement, fail to address individual learning needs or do not cover rare diseases.
Methods: In this work, an application for structured Abdominal Examination Training using Augmented Reality (AETAR) is presented. Required theoretical knowledge is displayed step by step via virtual indicators directly on the associated body regions. Exercises facilitate building up the routine in performing the examination. AETAR was evaluated in an exploratory user study with medical students (n=12) and teaching surgeons (n=2).
Results: Learning with AETAR was described as fun and beneficial. Usability (SUS=73) and rated suitability for teaching were promising. All students improved in a knowledge test and felt more confident with the abdominal examination. Shortcomings were identified in the area of interaction, especially in teaching examination-specific movements.
Conclusion: AETAR represents a first approach to structured abdominal examination training using augmented reality. The application demonstrates the potential to improve educational outcomes for medical students and provides an important foundation for future research and development in digital medical education.

Generalized lymphatic anomaly in a pediatric patient manifesting as a rare presentation of hemorrhagic pleural effusion: a case report.

Background: Generalized lymphatic anomaly (GLA) is a rare congenital lymphatic malformation (LM) characterized by multiple infiltrating lymphangiomas in various tissues. Owing to its rarity, information on this disease is obtained mainly through case reports, leading to delayed diagnosis. In this study, we reported a case of generalized lymphatic anomaly in a pediatric patient manifesting as hemorrhagic pleural effusion.

Kidney Stone Disease (KSD) is a prevalent urological condition, while abdominal obesity is on the rise globally. The conicity index, measuring body fat distribution, is crucial but under-researched in its relation to KSD and all-cause mortality. This study, using data from 59,842 participants in the NHANES (2007-2018), calculated the conicity index from waist circumference, height, and weight.

A high healthy lifestyle index (HLI) score, which reflects an adequate amount of sleep, no alcohol consumption, no smoking, a moderate to high physical activity level, a high quality diet, and a normal body mass index (BMI), has been associated with reduced risk of morbidity and mortality. We examined the relationship between the HLI and measurements of adipose and lean tissue volumes measured using magnetic resonance imaging (MRI). We studied 33,002 participants in the UK Biobank study, aged 40-69 years at enrolment.

We have incidentally observed a finding not yet described in the literature, on both cross-sectional imaging and fluoroscopy, to correlate with increased obstructive symptoms in our post sleeve gastrectomy patients. This case series aims to show postsurgical imaging cases with the common underlying finding of a pseudotumor associated with hiatal herniae and obstructive symptoms. Because this clinical presentation may, in some cases, warrant postsurgical revision, knowledge of the imaging findings and their potential clinical significance is useful to radiologists who interpret routine cross-sectional imaging examinations as well as fluoroscopic evaluations of these post sleeve gastrectomy patients.

Unlabelled: This study aimed to evaluate pathological findings on abdominal ultrasonography upon admission of children diagnosed with Multisystem Inflammatory Syndrome in Children (MIS-C) that were associated with a more severe disease course and the need for intensive care unit (ICU) admission. This retrospective and observational study was conducted between March 2020 and May 2022. Abdominal ultrasonography findings were evaluated in children diagnosed with MIS-C associated with SARS-CoV-2.
