Imaging finding and analysis of brain lymphoma in contrast-enhanced fluid attenuated inversion recovery sequence.

Objective: The purpose of this retrospective study was to report and analyze the image findings of contrast-enhanced fluid-attenuated inversion recovery (CE-FLAIR) sequence of lymphoma in the brain.

Material And Methods: Thirty-two immunocompetent patients with biopsy-proven diffuse large B-cell type lymphoma in the brain were evaluated with pre-treatment MRI examinations from August 2014 to April 2020. As stereotactic studies on the day of biopsy, FLAIR and T1-weighted axial images were acquired in 2 mm thickness, before and after administrating gadolinium-based contrast agents, with 3.

A novel blasted and grooved low profile pedicle screw able to resist high compression bending loads.

Objective: Polyaxial pedicle screws are a safe, useful adjunct to transpedicular fixation. However, the large screw head size can cause soft tissue irritation, high rod positioning, and facet joint injury. However, the mechanical resistance provided by small and low profile pedicle screws is very limited.

Can the 1.8 mm transnasal biopsy forceps instead of standard 2.2 mm alter rapid urease test and histological diagnosis?

Background And Aim: Biopsy specimens are taken during transnasal esophagogastroduodenoscopy with 1.8 mm forceps. The aims of this study were to compare the concordance of the Campylobacter-like organism (CLO) test and histological diagnoses between biopsies taken with 1.

Changes in liver stiffness measurement during antiviral therapy in patients with chronic hepatitis B.

Background/aims: The usefulness of liver stiffness measurement (LSM) for monitoring changes in fibrosis and inflammation in chronic hepatitis B (CHB) patients receiving antiviral therapy is unknown. The aim of this study was to evaluate changes in liver stiffness and correlate them with changes in serological markers and histology in CHB patients receiving entecavir.

Methodology: The study included 38 patients with CHB and 24 cirrhotic patients with CHB.

[Add on lamivudine to adefovir monotherapy for the treatment of lamivudine-resistant chronic hepatitis B patients].

Background/aims: Add on adefovir (ADV) to ongoing lamivudine (LAM) has been recommended as a standard therapy for the treatment of LAM resistance. In the past, switch to ADV monotherapy was suggested as an option for the treatment of LAM resistance, leading to frequent development of ADV resistance. However, ADV monotherapy has been still used in LAM-resistant patients because of low cost in Korea.
