A case of bilateral cortical blindness followed by generalised tonic-clonic seizure epilepsy in a patient with posterior reversible encephalopathy syndrome.

Posterior reversible encephalopathy syndrome (PRES) in end-stage kidney disease (ESKD) is rare, with ocular symptoms as the first manifestation being even rarer. Here, we report a case of PRES in a patient with ESKD, characterized by sudden binocular blurred vision followed by epilepsy, to improve the understanding of this syndrome among nephrologists and ophthalmologists. A 50-year-old female requested an ophthalmic consultation due to bilateral vision loss followed by generalised tonic-clonic seizures.

Morphological and functional abnormalities of ophthalmic artery in patients with ophthalmic vascular accidents.

Background: By observing and comparing the morphological and functional differences of the ophthalmic artery (OA) in patients with ocular vascular accidents (OVAs) due to iatrogenic embolism or non-iatrogenic occlusion, we propose a classification system based on the characteristics of OA on invasive digital subtraction angiography (DSA).

Methods: All patients undergoing ophthalmic arterial DSA within 1 week after the OVAs between January 2017 and December 2021 were enrolled and divided into different types, and the differences between iatrogenic embolism and non-iatrogenic occlusion categories were compared.

Results: A total of 27 eyes of 27 patients were included in this study.

Genome-wide identification, characterization and expression profiling of TLR family genes in Chromileptesaltivelis.

Toll-like receptors (TLRs) represent a prominent category of pattern recognition receptors that have been extensively investigated for their pivotal role in combating pathogen incursions. Despite this, there has been a notable absence of comprehensive identification and exploration of the immune response associated with the TLR family genes in C. altivelis.

Optimized early recurrence score for distal cholangiocarcinoma: A new attempt by adding imaging indicators.

Purpose: To improve the preoperative prediction efficacy for patients with risk for early recurrence (ER) of distal cholangiocarcinoma (DCC).

Methods: 56 patients pathologically diagnosed as DCC were included. Their clinical data and preoperative upper abdominal enhanced MSCT images were retrospectively reviewed to look for risk factors associated with ER.

Usefulness of magnetic resonance imaging characteristics in discriminating H3 K27M-mutant gliomas from wildtype gliomas in spinal cord.

Aim: The aim of this study was to determine the usefulness of magnetic resonance imaging (MRI) characteristics in discriminating H3 K27M-mutant gliomas from wildtype gliomas in the spinal cord.

Materials And Methods: Fifty-eight patients with spinal cord gliomas were enrolled in this study. The H3 K27 gene status was identified by Sanger sequencing or immunohistochemistry test of resection tumor specimens.

Assessing the predictability of the H3K27M status in diffuse glioma patients using frequency importance analysis on chemical exchange saturation transfer MRI.

Background And Objectives: In diffuse glioma patients, Lys-27-Met mutations in histone 3 genes (H3K27M) are associated with an aggravated prognosis and further decreased overall survival. By using frequency importance analysis on chemical exchange saturation transfer (CEST) MRI, this study aimed to assess the predictability of the H3K27M status in diffuse glioma patients.

Methods: Twenty-two patients diagnosed with diffuse glioma, with a known H3K27M status, were included in the present study.

Association of Sarcopenia With Mortality in Patients With Chronic Limb-Threatening Ischemia Undergoing Endovascular Revascularization.

Introduction: Chronic limb-threatening ischemia (CLTI) is the most severe form of peripheral artery disease and leads high mortality. Sarcopenia, characterized by the loss of muscle mass or poor muscle quality, is associated with adverse clinical outcomes. This study aimed to investigate the association between sarcopenia and the long-term outcomes in patients with CLTI after endovascular revascularization.

B Correction for 3T Amide Proton Transfer (APT) MRI Using a Simplified Two-Pool Lorentzian Model of Symmetric Water and Asymmetric Solutes.

Amide proton transfer (APT)-weighted MRI is a promising molecular imaging technique that has been employed in clinic for detection and grading of brain tumors. MTRasym, the quantification method of APT, is easily influenced by B0 inhomogeneity and causes artifacts. Current model-free interpolation methods have enabled moderate B0 correction for middle offsets, but have performed poorly at limbic offsets.

Frequency importance analysis for chemical exchange saturation transfer magnetic resonance imaging using permuted random forest.

Chemical exchange saturation transfer magnetic resonance imaging (CEST MRI) is a promising molecular imaging tool that allows sensitive detection of endogenous metabolic changes. However, because the CEST spectrum does not display a clear peak like MR spectroscopy, its signal interpretation is challenging, especially under 3-T field strength or with a large saturation B . Herein, as an alternative to conventional Z-spectral fitting approaches, a permuted random forest (PRF) method is developed to determine featured saturation frequencies for lesion identification, so-called CEST frequency importance analysis.

Magnetic resonance imaging indicators for neurological outcome after surgery in patients with intramedullary spinal ependymomas.

This is a retrospective study. The aim of this study was to determine the indicators of neurological outcome after surgery in patients with intramedullary spinal ependymomas by using magnetic resonance imaging (MRI).A total of 106 consecutive patients (mean age: 42.

AI-assisted CT imaging analysis for COVID-19 screening: Building and deploying a medical AI system.

The sudden outbreak of novel coronavirus 2019 (COVID-19) increased the diagnostic burden of radiologists. In the time of an epidemic crisis, we hope artificial intelligence (AI) to reduce physician workload in regions with the outbreak, and improve the diagnosis accuracy for physicians before they could acquire enough experience with the new disease. In this paper, we present our experience in building and deploying an AI system that automatically analyzes CT images and provides the probability of infection to rapidly detect COVID-19 pneumonia.

Targeted-gene sequencing of an undifferentiated gallbladder carcinoma: a case report.

Background: Undifferentiated carcinomas of the gallbladder are extremely rare. Most undifferentiated carcinomas are accompanied by adjacent foci of other conventional carcinomas, and a transition zone is shared between them. However, genetic alterations of undifferentiated gallbladder carcinoma and the similarities or differences between the undifferentiated carcinoma and the foci conventional carcinoma are unknown.

Intramedullary Spinal Cord Ganglioglioma Presenting as Hyperhidrosis: A Rare Case Report and Literature Review.

Background: Hyperhidrosis is caused by sympathetic dysfunction of the central or peripheral nervous system. However, intramedullary spinal cord tumors presenting with hyperhidrosis as an initial symptom have been rarely reported in the literature.

Case Description: This case involves an 18-year-old man who presented with abnormal enhanced sweating and flushing on the bilateral side of his face and neck that had persisted for 6 years.

Risk factor analysis of progressive spinal deformity after resection of intramedullary spinal cord tumors in patients who underwent laminoplasty: a report of 105 consecutive cases.

Objective: Laminoplasty has been used in recent years as an alternative approach to laminectomy for preventing spinal deformity after resection of intramedullary spinal cord tumors (IMSCTs). However, controversies exist with regard to its real role in maintaining postoperative spinal alignment. The purpose of this study was to examine the incidence of progressive spinal deformity in patients who underwent laminoplasty for resection of IMSCT and identify risk factors for progressive spinal deformity.
