Colonic Polyp Study: Differences in Adenoma Characteristics Based on Colonoscopy History over 5-Year Follow-Up Period.

: Timely detection and removal of colonic adenomas are critical for preventing colorectal cancer. : This study analyzed differences in colonic adenoma characteristics based on colonoscopy history by reviewing the medical records of 14,029 patients who underwent colonoscopy between January and June 2020 across 40 primary medical institutions in Korea. : Adenoma and advanced neoplasia characteristics varied significantly with colonoscopy history ( < 0.

Patient satisfaction and feasibility with a novel drug-injectable urethral catheter set for hyaluronic acid administration: a multicenter randomized trial.

Reducing the risk of urethral strictures after transurethral surgery for patients with bladder cancer requires effective strategies. We compared the clinical outcomes of a novel drug-injectable urethral catheter set (NIUS) with hyaluronic acid (HA) with those of the conventional intraurethral HA injection method. This six-center, prospective, randomized, single-blind trial included 192 male patients aged ≥ 20 years scheduled to undergo transurethral surgery.

Analysis of initial seizure characteristics in patients with infantile onset genetic epilepsy.

Objective: The present study aimed to investigate the initial clinical features of infantile-onset genetic epilepsy and compare initial seizure variables and responses to sodium channel blockers between SCN1A and non-SCN1A group.

Methods: We selected 122 patients, comprising 58 patients with SCN1A mutations and 64 patients with mutations in other than SCN1A, from our institutional database.

Results: Patients identified in the SCN1A group tended to present with fever, prolonged seizure duration, and hemiclonic seizure semiology.

Microwave welding with SiCNW/PMMA nanocomposite thin films: Enhanced joint strength and performance.

Most previously reported susceptors for microwave welding are in powder form. In this study, a thin-film susceptor was employed due to its uniform heating rate and ease of handling. Silicon carbide nanowhisker (SiCNW) were incorporated into a poly(methyl methacrylate) (PMMA) matrix to create a nanocomposite thin film, which served as the susceptor.

Phenotype of Relapsing Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease in Children.

Background And Purpose: To determine the clinical phenotypes, relapse timing, treatment responses, and outcomes of children with relapsing myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD).

Methods: We collected the demographic, clinical, laboratory, and radiological data of patients aged <18 years who had been diagnosed with MOGAD at Seoul National University Children's Hospital between January 2010 and January 2022; 100 were identified as positive for MOG antibodies, 43 of whom experienced relapse.

Results: The median age at onset was 7 years (range 2-16 years).
