Article Abstract

Purpose: To describe and compare the levels of pain severity and pain interference, pain catastrophizing, and associated factors between elderly Koreans living in South Korea and Korean Americans living in the United States with chronic pain.

Methods: An exploratory, comparative design was used for this study. A total of 270 individuals (138 Koreans living in South Korea and 132 Korean Americans living in the United States), aged more than 65 years, with self-reported chronic pain, and defined as at least 3 months of persistent musculoskeletal pain, is included. Outcome variables were pain severity, pain interference, and pain catastrophizing. Multivariate linear regression was conducted to examine factors associated with the outcome variables.

Results: In multivariate analysis, Korean Americans had higher levels of pain severity and pain catastrophizing than Koreans. Depressive symptoms, sleep quality, and health-related quality of life were significant factors for pain severity, pain interference, and pain catastrophizing for both groups. Among those factors, health-related quality of life was the most significant factor for predicting pain severity and pain interference, whereas depressive symptoms were the most significant factor for predicting pain catastrophizing for both groups.

Conclusions: Intra-ethnic differences in pain severity and pain catastrophizing were found between elderly Koreans living in South Korea and Korean Americans living in the United States.

Clinical Relevance: Because unfamiliar sociocultural and environmental factors may influence the pain responses, cultural differences and language barriers should be taken into account in pain research and management strategies for Asian immigrants in the United States. Psychological factors, including depressive symptoms, sleep quality, and health-related quality of life, should also be considered in chronic pain management for both elderly Koreans and Korean Americans.

Background: The prevalence of cancers and hematological malignancies is high and continues to grow. The severity of these pathologies calls for patients to be given the opportunity to express their values, particularly with regard to the intensity of treatment and the type of care they wish to receive. However, the prevalence of advance directives (ADs) in this population remains low.

Objective: There are very few studies on the use of a thermomechanical device for reducing injection pain in pediatric dentistry, especially for inferior alveolar nerve blocks (IANBs). The purpose of this study was to assess the efficacy of a thermomechanical device (Buzzy, Pain Care Labs) for reducing pain associated with an IANB for pediatric dental patients.

Methods: A total of 30 children, 5 to 8 years of age undergoing bilateral mandibular dental treatment requiring IANBs, were included in this randomized crossover study.

Objective: The purpose of this study was to compare nitrous oxide (N2O) vs virtual reality (VR) as methods for reducing pain and anxiety during a dental injection. The primary objectives were to assess acute changes in stress responses by comparing salivary cortisol levels between the 2 groups and differences in injection pain scores.

Methods: A total of 132 female subjects serving as their own control received maxillary lateral incisor infiltration injections with the use of either N2O or a VR headset during separate appointments spaced at least 2 weeks apart.
