Purpose: Interest in the quality of life (QoL) of patients with inflammatory bowel disease (IBD) has recently increased. Although measurement tools have been devised for IBD in general, there is no specific tool for measuring the QoL of patients with ulcerative colitis (UC). Therefore, we developed a QoL questionnaire specifically for patients with UC. Materials and Methods: The Korean Ulcerative Colitis-Specific Questionnaire (K-UCSQ) was developed through item generation, raw-scale construction, focus group meetings, and multi-center field tests. Two hundred patients with UC were recruited for a field test of the K-UCSQ, and subsequent responses to the Inflammatory Bowel Disease Questionnaire (IBDQ) were also obtained. After performing factor analyses to ensure construct validity, the K-UCSQ was finalized as a four-domain, 28-item questionnaire. Subsequent analyses evaluated the reliability of the K-UCSQ in terms of Cronbach’s alpha, concurrent validity in comparison with the pre-established IBDQ, and predictive validity of the area under the ROC curve (AUC) for clinically relevant QoL outcomes. Results: A Cronbach’s alpha of 0.94 showed excellent reliability. Furthermore, correlation analyses demonstrated the concurrent validity of the K-UCSQ in comparison with the IBDQ. The K-UCSQ also showed high validity in predicting the perceived overall health (AUC of 0.812 vs. 0.797 using the IBDQ) and past 2-week QoL (AUC of 0.864 vs. 0.859 using the IBDQ). Conclusion The newly developed K-UCSQ is concise, bathroom problem-emphasizing, and UC-specific, suggesting that it could be a valid and reliable UC-specific instrument for QoL measurement.

Chronic nonbacterial osteomyelitis (CNO) is histologically characterized by nonspecific osteitis. This inflammatory disorder, which lacks an infectious origin, typically presents with chronic pain and swelling at the affected site that can persist for months or even years. However, it is rare for CNO to affect the mandible. A 10-year-old girl presented with a primary complaint of pain in her left mandible. She had no significant medical or dental history. On examination, swelling was visible on the left buccal side, and imaging revealed radiolucent bone deterioration within the left mandible. This case report presents the radiological changes observed over a 12-year follow-up period. Variations in radiopacity, radiolucency, and periosteal reactions were noted periodically. This case highlights the radiological characteristics and findings that are crucial for the diagnosis of CNO, a condition for which no clear diagnostic criteria are currently available.

Further study is warranted to determine the association between estimated glomerular filtration rate (eGFR) or albuminuria and the risk of death from diverse causes. Methods: We screened >10 million general health screening examinees who received health examinations conducted in 2009 using the claims database of Korea. After the exclusion of those previously diagnosed with renal failure and those with missing data, 9,917,838 individuals with available baseline kidney function measurements were included. The primary outcome was mortality and cause-specific death between 2009 and 2019 identified through death certificates based on the diagnostic codes of International Classification of Diseases, 10th revision. Multivariable Cox regression analysis adjusted for various clinicodemographic and social characteristics was used to assess mortality risk. Results: The hazard ratio of death was significantly high in both the eGFR <60 mL/min/1.73 m2 and in the eGFR ≥120 mL/ min/1.73 m2 groups in univariable and multivariable regression analyses when compared to those within the reference range (eGFR of 90–120 mL/min/1.73 m2). The results were similar for death by cardiovascular, cancer, infection, endocrine, respiratory, and digestive causes. We also found that albuminuria was associated with higher risk of death regardless of eGFR range, and those in the higher categories of dipstick albuminuria showed higher risk. Conclusion: We reconfirmed the significant association between eGFR, albuminuria, and mortality. Healthcare providers should keep in mind that albuminuria and decreased eGFR as well as kidney hyperfiltration are independent predictors of mortality.

Insoles are used to treat various foot diseases, including plantar foot, diabetic foot ulcers, and refractory plantar fasciitis. In this study, we investigated the effects of 3-dimensional image-based (3-D) insole in healthy volunteers with no foot diseases. Additionally, the comfort of the 3-D insole was compared with that of a custom-molded insole. A singlecenter, randomized, open clinical trial was conducted to address the effectiveness of insole use in a healthy population with no foot or knee disease. Two types of arch support insoles were evaluated for their effectiveness: a 3-D insole and a custom-molded insole. Fifty Korean volunteers participated in the study and were randomly allocated into the “3-D insole” (n = 40) or “custom-molding insole” (n = 10) groups. All subjects wore 3-D insoles or custommolded insoles for 2 weeks. The sense of wearing shoes (Visual Analog Scale [VAS] and score) and fatigue of the foot were used to assess the insole effects at the end of the 2-week study period. The 3-D insole groups showed significantly improved sense of wearing shoes (VAS, p = 0.0001; score, p = 0.0002) and foot fatigue (p= 0.0005) throughout the study period.Although the number of subjects was different, the custom-molding insole group showed no significant changes in the sense of wearing shoes (VAS, 0.1188; score, p = 0.1483). Foot fatigue in the 3-D insole group improved significantly (p = 0.0005), which shows that a 3-D insole might have favorable effects on foot health in a healthy population.

Purpose: To compare the results of lacrimal syringing performed in clinical practice and under general anesthesia, and the clinical efficacy of lacrimal syringing under general anesthesia before endoscopic dacryocystorhinostomy and dacryoscintigraphy. Methods: The study included 148 eyes of 82 patients who underwent endoscopic dacryocystorhinostomy and silicone tube intubation from August 2018 to April 2019. The patients were examined with lacrimal syringing in clinical practice and re‐examined under general anesthesia. Based on the change in lacrimal syringing, the patients were assigned to inconsistent and consistent groups. The inconsistent group was subclassified into complete (‘regurgitation’ of lacrimal syringing changes to a ‘passage’ pattern) and partial improvement groups (the degree of regurgitation improves under general anesthesia). Results: Twenty (13.5%) eyes showed inconsistent results of lacrimal syringing performed in clinical practice and under general anesthesia; all showed improved passage under general anesthesia. The surgical results did not differ significantly (p = 0.336) between the consistent and inconsistent groups, but did between the complete and partial improvement groups (p < 0.01). Conclusions Lacrimal syringing under general anesthesia may enable an accurate preoperative diagnosis of the degree of obstruction. The combined results of dacryoscintigraphy and lacrimal syringing performed in clinical practice and under general anesthesia allow surgeons to evaluate the lacrimal drainage anatomy precisely and may be useful for predicting the functional success of endoscopic dacryocystorhinostomy.

Purpose: The purpose of this study is to understand the actual status of fundamentals of nursing practice (FNP) education at nursing colleges, and the difficulties of FNP operation in the early stages of the COVID-19. Methods: This study used a descriptive design. Data collection was conducted from December 9, 2020 to January 31, 2021 using the self-report questionnaire method for a total of 95 nursing colleges. The questionnaire consisted of characteristics related to FNP, changes in FNP education, difficulties in operating FNP, and countermeasures in the COVID-19 situation. Results: Changes in FNP due to COVID-19 were distribution of practice places, reduction of the number of students, short-term intensive classes, and reduction of face-to-face practice. Most colleges conducted FNP face-to-face, but some schools showed that FNP was conducted non-face-to-face. The difficulties of operating FNP that instructors experienced induced concerns about a decrease in student competency due to lack of face-to-face practice and an unofficial increase in the number of teaching hours and physical demands on instructors due to the expansion of the division. Conclusion In order to develop the capabilities of nursing students in other pandemic situations in the future, it is necessary to find systematic coping strategy to reduce the burden of FNP instructors, and to develop non-face-to-face online practice contents and consumables for online practice.
