Radiation Exposure in Concurrent Abdominoplevic and Chest CT Scans: An Analysis of Overlap and Clinical Impact.
J Radiol Prot
January 2025
Department of Biostatistics, Soon Chun Hyang University Hospital Bucheon, Bucheon, Gyeonggi-do, Korea (the Republic of).
This study investigated the additional radiation exposure, influencing factors, and clinical significance of overlapping Z-axis coverage in abdominopelvic CT scans performed consecutively after same-day chest CT scans. Data from 761 patients were analyzed, with measuring the total and overlapping Z-axis coverage of the portal venous phase in abdominopelvic CT scans. The average overlapping portion was 33.

Acta Oncol
January 2025
Department of Oncology, Oslo University Hospital, Norway.
Background And Purpose: To present the clinical outcomes of two series of patients treated with carbon-ion radiotherapy (CIRT) and definitive photon radiotherapy (RT) for adenoid cystic carcinoma of the head and neck (HN-ACC).
Material And Methods: The first cohort of six patients was referred from Oslo University Hospital (OUS) to Centro Nazionale di Adroterapia Oncologica (CNAO, Pavia, Italy) for CIRT in 2014-2017. The second cohort included 18 patients treated with definitive photon RT at OUS in 2005-2017.
Stress Granule Induction in Rat Retinas Damaged by Constant LED Light.
Invest Ophthalmol Vis Sci
January 2025
Universidad Nacional de Córdoba. Facultad de Ciencias Químicas. Departamento de Química Biológica Ranwel Caputto. Córdoba, Argentina.
Purpose: Stress granules (SGs) are cytoplasmic biocondensates formed in response to various cellular stressors, contributing to cell survival. Although implicated in diverse pathologies, their role in retinal degeneration (RD) remains unclear. We aimed to investigate SG formation in the retina and its induction by excessive LED light in an RD model.

Eur J Pediatr
January 2025
Pediatric Emergency Department, St. Christopher's Hospital for Children, Drexel University College of Medicine, Philadelphia, PA, USA.
Background: Computed tomography (CT) scans are widely used for evaluating children with acute atraumatic altered mental status (AMS) despite concerns about radiation exposure and limited diagnostic yield. This study aims to assess the efficacy of CT scans in this population and provide evidence-based recommendations.
Methods: A systematic review was conducted according to PRISMA guidelines.
Clinical consequence of the 4-week X-ray control after ESIN osteosynthesis of forearm fractures in children.
Eur J Trauma Emerg Surg
January 2025
Department of Orthopaedics and Traumatology, University Medical Center of the Johannes Gutenberg University, 55131, Mainz, Germany.
Purpose: The absence of evidence based general guidelines for radiographic follow-ups of pediatric diaphyseal forearm fractures treated with ESIN results in an arbitrary array of X-ray examinations. In most pediatric traumatology departments, an X-ray check is carried out 4 weeks after ESIN osteosynthesis of forearm shaft fractures to detect incipient consolidation of the fracture. However, the elevated sensitivity to ionizing radiation requires special precautions in the pediatric populations.
