Background: Strain elastography (SE) and shear wave elastography (SWE) are emerging techniques for evaluating the elasticity of soft tissue. This study aimed to determine interobserver and intraobserver reliability for elasticity measurements of different tissues and anatomic locations using SE and SWE. Methods: Ten healthy adult male individuals with 20 upper extremities participated in this study. The elasticities of the wrist extensor muscle, the common extensor tendon, and supraspinatus tendon were measured. Strain ratio and shear wave velocity were measured twice by 2 different examiners (examiner 1 with over 20 years of experience in musculoskeletal sonography and examiner 2 with 1 year of experience). Interobserver and intraobserver reliability was assessed using the intraclass correlation coefficient (ICC). Results: The 10 individuals’ age ranged from 28 to 35 years. In SE, interobserver reliabilities at the 3 anatomic locations (wrist extensor muscle, common extensor tendon, and supraspinatus tendon) showed fair to moderate agreement (ICC = 0.489, p = 0.076;ICC = 0.408, p = 0.131; and ICC = 0.296, p = 0.711, respectively). The intraobserver reliabilities of examiner 1 were moderate to substantial only at the wrist extensor muscle and the common extensor tendon (ICC = 0.563, p = 0.039 and ICC = 0.702, p = 0.006, respectively). In SWE, interobserver reliabilities for the wrist extensor muscle and the supraspinatus tendon were moderate to substantial (ICC = 0.756, p = 0.002 and ICC = 0.565, p = 0.039, respectively). The intraobserver reliabilities of examiner 1 at the 3 anatomic locations were almost perfect (ICC = 0.843, p = 0.001; ICC = 0.800, p = 0.001; and ICC = 0.825, p = 0.001, respectively).The results of examiner 2 showed almost perfect agreement at the wrist extensor muscle (ICC = 0.886, p = 0.001) and moderate to substantial agreement at the tendons of the common extensor and supraspinatus (ICC = 0.592, p = 0.029 and ICC = 0.682, p = 0.008, respectively). Conclusions SWE is a reliable method for assessing the flexibility of soft tissue, but it is affected by expertise and the specific anatomical site.

In a completely edentulous patient who cannot have implant-retained overdentures due to medical history and economic circumstances, a suction-effective complete denture utilizing the closed-mouth impression technique is being used to secure high retention. In this case, both a conventional complete denture using the open-mouth impression technique and a suction-effective complete denture using the closed-mouth impression technique were fabricated for a single completely edentulous patient. The results demonstrated that both methods provided excellent outcomes in terms of function, esthetics, and patient satisfaction. Conventional complete dentures increase the area of denture-bearing pressure to ensure retention and stability, whereas suction-effective complete dentures achieve retention by sealing the entire border of the denture. Since there are characteristic differences in the clinical and laboratory procedures due to differences in the concept of denture fabrication, this was compared through this case report.

Colorectal cancer is the third most common cancer in Korea and the third leading cause of death from cancer. Treatment outcomes for colon cancer are steadily improving due to national health screening programs with advances in diagnostic methods, surgical techniques, and therapeutic agents.. The Korea Colon Cancer Multidisciplinary (KCCM) Committee intends to provide professionals who treat colon cancer with the most up-to-date, evidence-based practice guidelines to improve outcomes and help them make decisions that reflect their patients’ values and preferences. These guidelines have been established by consensus reached by the KCCM Guideline Committee based on a systematic literature review and evidence synthesis and by considering the national health insurance system in real clinical practice settings. Each recommendation is presented with a recommendation strength and level of evidence based on the consensus of the committee.
