Rituximab (monoclonal anti-CD20 antibody) induced posterior reversible encephalopathy syndrome (PRES): A case report and literature review.

Posterior reversible encephalopathy syndrome (PRES) is an uncommon neurological condition characterized by reversible subcortical vasogenic edema that primarily affects the posterior areas of the brain. Subcortical vasogenic edema resulting from endothelial injury and hypertension is the pathogenesis. Here, we present a 23-year-old female patient with systemic lupus erythematosus (SLE) and lupus nephritis who developed PRES following Rituximab (a monoclonal anti-CD-20 antibody) administration.

Photo-thermo-optical modulation of Raman scattering from Mie-resonant silicon nanostructures.

Raman scattering is sensitive to local temperature and thus offers a convenient tool for non-contact and non-destructive optical thermometry at the nanoscale. In turn, all-dielectric nanostructures, such as silicon particles, exhibit strongly enhanced photothermal heating due to Mie resonances, which leads to the strong modulation of elastic Rayleigh scattering intensity through subsequent thermo-optical effects. However, the influence of the complex photo-thermo-optical effect on inelastic Raman scattering has yet to be explored for resonant dielectric nanostructures.

Left Anterolateral Medullary Compression Due to Vertebral Artery Dolichoectasia: A Case Report and Review of Literature.

Vertebral artery dolichoectasia, characterized by the elongation, dilation, and tortuosity of the vertebral arteries, poses significant clinical challenges due to its potential to compress adjacent neural structures, particularly the medulla oblongata. This case report presents a 73-year-old hypertensive female with recurrent episodes of falls and transient loss of consciousness. Initial assessments including echocardiography and a four-vessel Doppler study were unremarkable, prompting further evaluation with MRI.

The Role of Plain CT in Assessing and Estimating Normal Values of Pericardial Fat Pad Thickness and Their Correlation With Patient's Age, Gender, Body Weight, and Body Mass Index.

Introduction The pericardial fat pad, located anteriorly to the heart between the pericardium and myocardium, has garnered significant interest in cardiovascular research due to its potential role in the pathophysiology of various cardiac conditions. Despite its proximity to the myocardium, it is distinct from the epicardial fat depot found between the myocardium and the visceral layer of the pericardium. Studies have shown that excess pericardial fat is associated with an increased risk of heart failure and other cardiovascular diseases.
