Graded Anterior Partial-thickness Blepharotomy for the Correction of Idiopathic Unilateral Upper Eyelid Retraction: A Case Report and Literature Review.
Plast Reconstr Surg Glob Open
January 2025
From the Department of Plastic and Burn Surgery, The First Affiliated Hospital of Chongqing Medical University, Chongqing, China.
Idiopathic upper eyelid retraction is a rare ocular symptom characterized by abnormal upward displacement of the upper eyelid, often without any identifiable systemic disease. This condition not only affects the patient's appearance but may also have a certain impact on their daily life and mental health. We report a case of adult idiopathic unilateral upper eyelid retraction, and based on the patient's specific condition, we used graded anterior plate blepharoplasty for treatment.

Background: Isolated rapid-eye movement (REM) sleep behavior disorder (iRBD) is characterized by abnormal behaviors in REM sleep and is considered as a prodromal symptom of alpha-synucleinopathies. Resting-state functional magnetic resonance imaging (rsfMRI) studies have unveiled altered functional connectivity (rsFC) in patients with iRBD. However, the associations between intra- and inter-network rsFC with clinical symptoms and neuropsychological functioning in iRBD remain unclear.

Department of Radiology, College of Medicine, University of Florida, Gainesville, FL.
Purpose: This study evaluated beam quality and radiation dosimetry of a CT scanner equipped with a novel detector and filtration technology called PureVision Optics (PVO). PVO features miniaturized electronics, a detector cut with microblade technology, and increased filtration in order to increase x-ray detection and reduce image noise.
Methods: We assessed the performance of two similar 320-detector CT scanners: one equipped with PVO and one without.
For indirect time-of-flight (iToF) cameras, we proposed a modeling approach focused on addressing random error. Our model characterizes random error comprehensively by detailing the propagation of error introduced by signal light, ambient light, and dark noise through phase calculation and system correction processes. This framework leverages correlations between incident light and tap responses to quantify noise impacts accurately.

Parametric mapping has become a standard of care technique for the non-invasive assessment of myocardial edema and fibrosis. Conventional MOLLI-based T1 mapping is susceptible to many confounding effects particularly in the pediatric population. The requirement for compliant breath holds is a major limitation for younger or more ill patients.
