PURPOSE: The purpose of this study was to identify the moderating and mediating effects of resilience in the relationship between emotional labor and job satisfaction among nurses working in intensive care units (ICUs).METHOD: The participants were 144 ICU nurses from three university hospitals. Data were collected using structured questionnaires and analyzed by t-test, ANOVA, Scheffé test, Pearson correlation coefficients, and multiple regression analysis, using SPSS 25.0. The mediating effect of resilience in the relationship between emotional labor and job satisfaction was analyzed by multiple regression analysis according to Baron and Kenny's procedure.RESULTS: Statistically significant negative correlations were found between emotional labor and resilience (r=−.21, p<.014) and between emotional labor and job satisfaction (r=−.34, p<.001). A significant positive correlation was found between resilience and job satisfaction (r=.31 p<.001). A partial mediating effect by resilience was found between emotional labor and job satisfaction (Z=−2.11, p =.034), but no moderating effect was found.CONCLUSION: To improve the job satisfaction of ICU nurses, evaluation of their emotional labor, resilience, and interventions are necessary to alleviate emotional labor and improve resilience.

Colonic diffuse ganglioneuromatosis is an extremely rare disease in which multiple tumors derived from the ganglion cells, nerve fibers, and supporting cells are distributed in the colon. It is generally considered to be a benign neoplastic condition and is occasionally associated with rare hereditary conditions such as neurofibromatosis type I or multiple endocrine neoplasia type 2B. Here, we report a case of a patient in whom colon cancer developed 12 years after the initial diagnosis of colonic diffuse ganglioneuromatosis, which suggests a possible association between colonic diffuse ganglioneuromatosis and colorectal cancer.

PURPOSE: To evaluate the incidence of retinal angiomatous proliferation (RAP) and retinal pigmented epithelial detachment (PED) in Korean age-related macular degeneration (ARMD) patients and results of photodynamic therapy (PDT) with verteporfin. METHODS: Between May 2001 and December 2004, two hundred fifty-eight patients diagnosed of ARMD were evaluated and nine eyes of seven patients were as having RAP with PED. All patients underwent two or more sessions of PDT. Best-corrected visual acuity (BCVA), fundus photography, fluorescein angiography and ICG angiography were performed before and after treatment. RESULTS: The incidence of RAP with PED was 2.8%. The mean age of onset was 71.7 and five of seven patients were female. After 17 months and mean 2.3 PDT treatments, mean BCVA decreased from 0.2 to 0.04. In two eyes, additional Transpupillary thermotherapy was undertaken. Occlusion of RAP and flattening of PED was observed in one eye, and four evolved toward stage 3 RAP. Three eyes with PDT developed tear of retinal pigmented epithelium. CONCLUSIONS: Korean ARMD patients showed a low incidence of RAP and poor visual outcomes even with treatment.

Background/Aims: The worldwide coronavirus disease 2019 pandemic has led endoscopists to use personal protective equipment (PPE) for infection prevention. This study aimed to investigate whether wearing a face shield as PPE affects the quality of colonoscopy. Methods: We reviewed the medical records and colonoscopy findings of patients who underwent colonoscopies at Asan Medical Center, Korea from March 10 to May 31, 2020. The colonoscopies in this study were performed by five gastroenterology fellows and four expert endoscopists. We compared colonoscopy quality indicators, such as withdrawal time, adenoma detection rate (ADR), mean number of adenomas per colonoscopy (APC), polypectomy time, and polypectomy adverse events, both before and after face shields were added as PPE on April 13, 2020. Results: Of the 1,344 colonoscopies analyzed, 715 and 629 were performed before and after the introduction of face shields, respectively. The median withdrawal time was similar between the face shield and no-face shield groups (8.72 minutes vs 8.68 minutes, p=0.816), as was the ADR (41.5% vs 39.8%, p=0.605) and APC (0.72 vs 0.77, p=0.510). Polypectomy-associated quality indicators, such as polypectomy time and polypectomy adverse events were also not different between the groups. Quality indicators were not different between the face shield and no-face shield groups of gastroenterology fellows, or of expert endoscopists. Conclusions Colonoscopy performance was not unfavorably affected by the use of a face shield. PPE, including face shields, can be recommended without a concern about colonoscopy quality deterioration.

Cronkhite-Canada syndrome (CCS) is a rare, noninherited gastrointestinal polyposis syndrome associated with ectodermal changes such as alopecia, nail dystrophy, and cutaneous hyperpigmentation. The etiology and pathogenesis of CCS are not known, but diarrhea, malnutrition, gastrointestinal bleeding, and infection may occur in the affected patient; moreover, this condition could be fatal. However, previous reports have described several cases of spontaneous remission. We report a 60-year-old man who was incidentally found to have colonic polyposis, alopecia, and hypogeusia and was diagnosed to have CCS. However, this patient experienced spontaneous remission, including regrowth of body hair and alleviation of bowel inflammation, without any specific medications such as steroids, antibiotics, or proton pump inhibitors.

15-Hydroxyprostaglandin dehydrogenase (15-PGDH) is downregulated during the early stages of colorectal carcinogenesis. The aim of the present study was to investigate the potential role of 15-PGDH in normal-appearing colorectal mucosa as a biomarker for predicting colorectal neoplasms. We obtained paired tumor and normal tissues from the surgical specimens of 32 sporadic colorectal cancer patients. mRNA expression of 15-PGDH was measured using a quantitative real-time PCR assay. We evaluated the association between 15-PGDH mRNA expression in normal-appearing mucosa, the presence of synchronous adenoma, and the cumulative incidence of metachronous adenoma. The relative 15-PGDH expression of normal-appearing mucosa in patients with synchronous adenoma was significantly lower than in patients without synchronous adenoma (0.71 vs 1.00, P = 0.044). The patients in the lowest tertile of 15-PGDH expression in normal-appearing mucosa were most likely to have synchronous adenoma (OR: 10.5, P = 0.024). Patients with low 15-PGDH expression in normal-appearing mucosa also demonstrated more advanced stage colorectal cancer (P = 0.045). However, there was no significant difference in the cumulative incidence of metachronous adenoma according to 15-PGDH mRNA expression in normal-appearing mucosa (P = 0.333). Hence, 15-PGDH in normal-appearing colorectal mucosa can be a useful biomarker of field effect for the prediction of sporadic synchronous neoplasms.

BACKGROUND/AIMS: Accurately diagnosing inflammatory bowel disease (IBD) remains a challenge, but is crucial for providing proper management for affected patients. The aim of the present study was to evaluate the frequency of change in diagnosis in Korean patients who were referred to our institution with a diagnosis of IBD. METHODS: We enrolled 1,444 patients diagnosed with ulcerative colitis (UC) and 1,452 diagnosed with Crohn's disease (CD), who had been referred to the Asan Medical Center between January 2010 and December 2014. These patients were assessed and subsequently classified as having UC, CD, indeterminate colitis, possible IBD, or non-IBD. RESULTS: During a median follow-up of 15.9 months, 400 of the 2,896 patients (13.8%) analyzed in this study experienced a change in diagnosis. A change in diagnosis from UC to CD, or vice-versa, was made in 24 of 1,444 patients (1.7%) and 23 of 1,452 patients (1.6%), respectively. A change to a non-IBD diagnosis was the most common modification; 7.5% (108 of 1444) and 12.7% (184 of 1452) of the patients with a referral diagnosis of UC and CD, respectively, were reclassified as having non-IBD. Among the 292 patients who were ultimately determined not to have IBD, 135 (55 UC and 80 CD cases) had received IBD-related medication. CONCLUSIONS: There are diagnostic uncertainties and difficulties in relation to IBD. Therefore, precise assessment and systematic follow-up are essential in the management of this condition.

BACKGROUND/AIMS: Endoscopic ultrasound-guided fine needle aspiration and/or biopsy (EUS-FNA/B) have been used to diagnose subepithelial tumors (SETs) and extraluminal lesions in the gastrointestinal tract. Our group previously reported the usefulness of EUS-FNA/B for rectal and perirectal lesions. This study reports our expanded experience with EUS-FNA/B for rectal and perirectal lesions in terms of diagnostic accuracy and safety. We also included our new experience with EUS-FNB using the recently introduced ProCore needle. METHODS: From April 2009 to March 2014, EUS-FNA/B for rectal and perirectal lesions was performed in 30 consecutive patients. We evaluated EUS-FNA/B performance by comparing histological diagnoses with final results. We also investigated factors affecting diagnostic accuracy. RESULTS: Among 10 patients with SETs, EUS-FNA/B specimen results revealed a gastrointestinal stromal tumor in 4 patients and malignant lymphoma in 1 patient. The diagnostic accuracy of EUS-FNA/B was 50% for SETs (5/10). Among 20 patients with non-SET lesions, 8 patients were diagnosed with malignant disease and 7 were diagnosed with benign disease based on both EUS-FNA/B and the final results. The diagnostic accuracy of EUS-FNA/B for non-SET lesions was 75% (15/20). The size of lesions was the only factor related to diagnostic accuracy (P=0.027). Two complications of mild fever and asymptomatic pneumoperitoneum occurred after EUS-FNA/B. CONCLUSIONS: The overall diagnostic accuracy of EUS-FNA/B for rectal and perirectal lesions was 67% (20/30). EUS-FNA/B is a clinically useful method for cytological and histological diagnoses of rectal and perirectal lesions.
