We reviewed articles using computational RF dosimetry to compare the Specific Anthropomorphic Mannequin (SAM) to anatomically correct models of the human head. Published conclusions based on such comparisons have varied widely. We looked for reasons that might cause apparently similar comparisons to produce dissimilar results. We also looked at the information needed to adequately compare the results of computational RF dosimetry studies. We concluded studies were not comparable because of differences in definitions, models, and methodology. Therefore we propose a protocol, developed by an IEEE standards group, as an initial step in alleviating this problem. The protocol calls for a benchmark validation study comparing the SAM phantom to two anatomically correct models of the human head. It also establishes common definitions and reporting requirements that will increase the comparability of all computational RF dosimetry studies of the human head.

Background: Intraoperative ultrasound is becoming a common tool in neurosurgery. However, effective simulation methods are limited. Current, commercial, and homemade phantoms lack replication of anatomical correctness and texture complexity of brain and tumour tissue in ultrasound images.

Objectives: The aim of the study was to evaluate anatomical and functional outcomes of the Smaller-Incision New Generation Implantable Miniature Telescope (SING IMT™) in patients with bilateral advanced age-related macular degeneration (AMD).
Methods: This non-comparative retrospective single-surgeon interventional case series included patients with bilateral late-stage AMD who underwent cataract surgery and SING IMT™ implantation at the Sant'Anna University Hospital, University of Ferrara, Italy. The main outcome measures included corrected distance (CDVA) and near visual acuity (CNVA), endothelial cell loss (ECL), and incidence of complications.

Purpose: To assess the effectiveness of split-thickness amniotic membrane (SAM) grafts in achieving closure of refractory or large macular holes (MH).
Methods: This retrospective study reviewed data from patients who underwent surgical repair of MHs using SAM grafts between January 2019 and December 2023. Key parameters, including best-corrected visual acuity (BCVA) and MH size, were evaluated both preoperatively and postoperatively.

Objectives: Out-of-hospital cardiac arrest (OHCA) victims receiving defibrillation from an automated external defibrillator (AED) placed early in the chain of survival are more likely to survive. We sought to explore the accuracy of AED pad placement for lay rescuers (LR) and first responders (FR).
Methods: We conducted a secondary analysis of data collected during randomized OHCA simulation trials involving LRs and FRs.
