High-altitude cerebral edema manifesting as T2/FLAIR hyperintensity and microbleeds in the white matter on MRI brain

Radiology Case Reports, 2023
High-altitude cerebral edema is a rare type of acute mountain illness characterized by consciousness disruption and truncal ataxia. Here we discuss a 40-year-old nondiabetic, nonsmoker male who went on a tour to Nanga Parbat.

A Dual Parameter Synchronous Monitoring System of Brain Edema Based on the Reflection and Transmission Characteristics of Two-Port Test Network

IEEE Access, 2019
As a common secondary disease, edema after traumatic brain injury (TBI) can increase brain volume, resulting in elevated intracranial pressure (ICP), brain shift, and cerebral hernia, and can eventually lead to death.

RefineCatDiff: Toward High‐Quality Medical Image Segmentation via a Categorical Diffusion Refinement Framework

Advanced Intelligent Systems, EarlyView.
This study proposes RefineCatDiff, a refinement framework for high‐quality medical image segmentation. By developing a categorical distribution‐based discrete diffusion process for refinement, the framework aligns well with the characteristics of image segmentation tasks. Experimental results on multiple datasets across different modalities demonstrate

Leveraging Compressed Sensing and Radiomics for Robust Feature Selection for Outcome Prediction in Personalized Ultra‐Fractionated Stereotactic Adaptive Radiotherapy

Advanced Intelligent Systems, EarlyView.
A compressed sensing (CS)‐based feature selection method is proposed to select the most informative elements in the radiomic features extracted from medical images of personalized ultra‐fractionated stereotactic adaptive treatment. The CS‐based approach is able to simplify the feature selection process and enhance the accuracy and robustness of a ...

ffects of renin –angiotensin system inhibition on ischemic brain edema formation and blood – brain barrier disruption following focal cerebral ischemia in rat [PDF]

Background & objectives: Ischemic brain edema is one of the most important complications of cerebral infarction. Edema aggravates the primary ischemic injury to the brain. It was demonstrated that the renin-angiotensin system (RAS) and its active peptide

Worsening of cerebral hyperemia by the administration of terlipressin in acute liver failure with severe hepatic encephalopathy [PDF]

, 2004
There is increasing evidence that terlipressin is useful in patients with cirrhosis and hepatorenal syndrome, but there are no data of its use in patients with acute liver failure (ALF) in whom hepatorenal syndrome is common.

Prenatal Brain Abnormalities in Sodium‐Dependent Multivitamin Transporter Deficiency

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT In treatable neurometabolic disorders, early diagnosis and prompt initiation of treatment are key to improved survival and outcomes. Biallelic variants in SLC5A6 cause sodium‐dependent multivitamin transporter deficiency (OMIM # 618973), which is treatable with high‐dose pantothenic acid, biotin, and alpha lipoic acid.

Case Report: Unusual Neurological Features of Leigh Syndrome due to m.8993T>G Pathogenic Variant in the MT‐ATP6 Gene

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The MT‐ATP6 gene m.8993T>G pathogenic variant has been associated with Leigh syndrome, especially in patients exhibiting a high degree of heteroplasmy. Although patients may present with a wide phenotypic spectrum, characteristic findings include bilateral, symmetric hyperintensities in the basal ganglia and brainstem on brain MRI ...
