Imaging of unicentric hyaline-vascular variant of Castleman disease: Emphasis on perilesional fat stranding and fatty proliferation.

The hyaline-vascular variant of Castleman disease (HVCD) is relatively uncommon and demonstrates no specific clinical or laboratory findings; therefore, its preoperative diagnosis warrants a radiological evaluation. This study aimed to review imaging findings of HVCD, focusing on perilesional fat stranding and fatty proliferation. Patients with a pathologically confirmed HVCD diagnosis who had undergone CT were recruited from five hospitals from January 2000 to March 2023.

Image-based Re-evaluation of the JCOG0911 Study Focusing on Tumor Volume and Survival, Disease Progression Diagnosis, and Radiomic Prognostication for Newly Diagnosed Glioblastoma.

Purpose: To re-evaluate images recovered from JCOG0911, a randomized phase 2 trial for newly diagnosed glioblastoma (nGBM) conducted by the Japan Clinical Oncology Group (JCOG) Brain Tumor Study Group.

Methods: The correlation between tumor volumes and survival was evaluated, followed by progression-free survival (PFS) analysis by independent central review based on Response Assessment in Neuro-Oncology (RANO) criteria using MRI recovered from 118 nGBM patients enrolled in the JCOG0911 trial. A radiomic analysis was also performed to identify radiomic features predictive of nGBM prognosis.

Initial adjustments in the dosage and rest period of gemcitabine plus cisplatin therapy for patients with incurable biliary tract cancer based on baseline estimated glomerular filtration rate (eGFR) values may be crucial for treatment outcomes and the preservation of renal function.

Background: Gemcitabine (GEM) and cisplatin (CDDP) combination therapy (GC therapy) is the standard 1st-line regimen for incurable biliary tract cancers (BTCs). However, the correlation between dynamic changes in renal function and the outcomes of GC therapy remains unclear. This study aimed to clarify the association between renal function alterations and treatment outcomes after GC therapy.

The impact of maternal prenatal psychological distress on the development of epilepsy in offspring: The Japan Environment and Children's Study.

The relationship between maternal prenatal psychological distress and epilepsy development in offspring has not yet been clarified. Herein, we used a dataset obtained from the Japan Environment and Children's Study, a nationwide birth cohort study, to evaluate the association between six-item Kessler Psychological Distress Scale (K6) scores and epilepsy among 1-3 years old. The data of 97,484 children were retrospectively analyzed.

Ophthalmic artery originating from contralateral internal carotid artery associated with ipsilateral agenesis of internal carotid artery.

Congenital absence of the internal carotid artery is a rare anatomical variant. The primarily reported origins of the ophthalmic artery associated with this variant are the posterior communicating, middle cerebral, and external carotid arteries. We report the case of a patient without an internal carotid artery whose ophthalmic artery originated from the contralateral internal carotid artery.
