Side- and Sinus-Specific Relationships between Chronic Rhinosinusitis and Ischemic Stroke Using Imaging Analyses.

Recent studies have reported chronic rhinosinusitis (CRS) as an independent risk factor for stroke. However, the association with stroke depending on the affected sinuses has not been explored. This study aimed to elucidate the side- and sinus-specific relationship between CRS and ischemic stroke through imaging analyses.

A case of vocal cord gnathostomiasis diagnosed with sectional morphologies in a histopathological specimen from a Chinese woman living in Korea.

This study aimed to describe a rare case of gnathostomiasis in the vocal cord. A 54-year-old Chinese woman living in Korea visited with a chief complaint of voice change at the outpatient department of otorhinolaryngology in Hallym Sacred Heart Hospital, Hallym University on August 2, 2021. She had eaten raw conger a few weeks before the voice change developed, but her medical history and physical examinations demonstrated neither gastrointestinal symptoms nor other health problems.

Foreign Body Complications in Ears due to Mishandled Hearing Aid Fitting and Proposed Clinical Guidelines to Address the Complications.

Background: South Korea has one of the world's fastest aging populations and is witnessing increased age-related hearing impairment cases as well as an increase in the number of hearing aid users. The aim of this study was to analyze complications caused by hearing aid mold materials. In addition, we hope to raise awareness of the harm and danger that inexperienced hearing aid providers can cause to patients.

Nanoporous Material Recognition via 3D Convolutional Neural Networks: Prediction of Adsorption Properties.

Nanoporous materials can be effective adsorbents for various energy applications. Because of their abundant number, brute-force-based material discovery can, however, be challenging. Data-driven approaches can be advantageous for such purposes.

Electrostatic Potential Optimized Molecular Models for Molecular Simulations: CO, CO, COS, HS, N, NO, and SO.

Molecular simulations have been widely employed in the discovery of nanoporous materials, such as metal-organic frameworks (MOFs) and zeolite, for energy- and environment-related applications. To achieve simulation predictions with better accuracy, we herein present a collection of molecular models, including carbon monoxide (CO), carbon dioxide (CO), carbonyl sulfide (COS), hydrogen sulfide (HS), nitrogen (N), nitrous oxide (NO), and sulfur dioxide (SO). These models, denoted as electrostatic potential optimized molecular models (ESP-MMs), are systematically developed to not only reproduce experimental vapor-liquid equilibrium but also have accurate electrostatic potential representation surrounding the molecules.

Transcatheter closure of small ductus arteriosus with amplatzer vascular plug.

Purpose: The purpose of this study was to share our experience of transcatheter closure of small patent ductus arteriosus (PDA) by using an Amplatzer vascular plug (AVP).

Methods: We reviewed the medical records of 20 patients who underwent transcatheter closure at Samsung Medical Center and Sejong General Hospital from January 2008 to August 2012. The size and shape of the PDAs were evaluated by performing angiograms, and the PDA size and the AVP devices size were compared.

Device size for transcatheter closure of ovoid interatrial septal defect.

Background: For successful transcatheter closure of an atrial septal defect with the Amplatzer septal occluder, the shape of the defect should be considered before selecting the device size. The purpose of this study was to evaluate the results of transcatheter closure of an ovoid atrial septal defect.

Methods: Between January 2010 and February 2012, cardiac computer tomography examinations were performed in 78 patients who subsequently underwent transcatheter closure of an atrial septal defect.
