Correspondence between white matter hyperintensities and regional grey matter volumes in Alzheimer's disease.
Front Aging Neurosci
September 2024
Department of Neurology, The First Affiliated Hospital of China Medical University, Shenyang, China.
Objective: White matter hyperintensities (WMH) are the most common neuroimaging manifestation of cerebral small vessel disease, and is frequently observed in Alzheimer's disease (AD). This study aimed to investigate the relationship between WMH and cognition and to verify the mediation of grey matter atrophy in this relationship.
Methods: The diffusion tensor imaging (DTI) technique analyses white matter fiber tract to assess white matter integrity.
Treatment Of Post-Operative Chylothorax: The Role Of Intranodal Lymphangiography And Thoracic Duct Disruption.

Radiology Department, Centro Hospitalar de Vila Nova de Gaia e Espinho, Portugal.
Thoracic duct embolization has been increasingly adopted as a first-line therapy of chylothorax and this procedure includes lipiodol lymphangiography, thoracic duct access and embolization. Lymphangiography itself has a therapeutic role, with volume-dependent success rates of 37%-97% and even a reported 100% success rate in outputs of < 500 mL/day. We present a clinical case of a 48-years-old man diagnosed with esophageal squamous cell carcinoma, who underwent esophagectomy and presented with post-operative high-output (> 1L/day) chylothorax; thoracic duct embolization was proposed.

Department of Radiology, Aichi Medical University, Nagakute, JPN.
Introduction Single or multi-fraction (mf) stereotactic radiosurgery (SRS) is an indispensable treatment option for brain metastases (BMs). The integration of volumetric modulated arc therapy (VMAT) into linac-based SRS is expected to further enhance efficacy and safety and to expand the indications for the challenging type of BMs. However, the optimal treatment design and relevant optimization method for volumetric modulated arc-based radiosurgery (VMARS) remain unestablished with substantial inter-institutional differences.

J Otolaryngol Head Neck Surg
May 2022
Department of Otorhinolaryngology-Head and Neck Surgery, Capital Institute of Pediatrics, Beijing, People's Republic of China.
Background: The ability of saline irrigation to detach the mucous and the flow-limiting effect of the nasal valve has not been well explored. The objective of this study was to compare the removal efficiency of a novel irrigation device with an extended nozzle versus a classic rinse bottle.
Methods: Transparent casts of the unoperated sinonasal cavity were made by 3D printing.
Development of an apparatus and procedure for evaluating the efficiency of nasal irrigation.
Eur Arch Otorhinolaryngol
August 2022
Department of Otorhinolaryngology-Head and Neck Surgery, Capital Institute of Pediatrics, Beijing, People's Republic of China.
Background: Although different methods of nasal irrigation have been utilized, irrigation efficiency in nasal cavities has not been well assessed. The objective of this study was to develop an apparatus and procedure for evaluating the irrigation efficiency and to explore the optimal head position during irrigation.
Methods: Casts of the left sinonasal cavity from a healthy volunteer were made from high-resolution-computed tomography data using 3D printing with composite materials.
