Historically, mineral compound herbal medicines have long been used in treatments of immune-related diseases in Korea, China and other Asian countries. In this study, we inv-estigated the anti-inflammatory effect of egg white combined with chalcanthite (IS4) on lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. RAW 264.7 cells cultured with LPS and various con-centrations of IS4 were analyzed to determine the production of pro-inflammatory cytokines and mediators by using enzyme-linked immune sorbent assays (ELISAs). IS4 concentration inhibited the production of interleukin-1beta (IL-1β), interleukin-6 (IL-6), and granulocyte-macrophage colony-stimulating factor (GM-CSF) induced by LPS. IS4 at high concentrations (25 and 50`㎍/ml) inhibited, in concentration-dependent manner, the expression of tumor necrosis factor-alpha (TNF–α) stimulated by LPS. IS4 has shown an anti-inflammatory effect in RAW 264.7 cells.

Purpose: This study aimed to develop an untact visit service based on an application that can be utilized in the pediatric intensive care unit (PICU) during COVID-19. Methods: This study adopted the double diamond process of service design comprising the discovery, defining, and development stages. Results: We developed an untact visit service based on an application that considered the child's status, schedule, photo, and video messages, and so on. Moreover, we derived a service flow regarding the required roles and the type of flow shown between each stakeholder. Conclusion: Considering the ongoing pandemic, the untact visit service is designed to increase rapport and participation of parents, share the child's information in real-time, and provide one-stop service without increasing healthcare providers' work. It will be a useful visit service that can be applied and evaluated in various hospital settings and the PICU. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was developing a nasogastric tube feeding algorithm to prevent aspiration pneumonia. Methods: The algorithm was developed through a methodological design. First, a pilot study was performed to determine the incidence of pneumonia. The second step was development of a preliminary algorithm through a literature review and collection of nurse opinions. The third step was to establish content validity using a panel of 12 experts. The fourth step was revision of the algorithm. Next, 20 intensive care unit nurses applied the revised algorithm for six months to their actual treatment, and the practical feasibility was verified after that. Results: In the patients for whom this algorithm was applied, no cases of pneumonia occurred. The algorithm that was developed by the present author was suitable for clinical application. Conclusion: The effect and practical feasibility of the algorithm was tested with a few patients in this study. The effect of this algorithm should be examined by applying it to more patients on an ongoing basis. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to investigate incidence of delirium in the pediatric intensive care unit (PICU) and to analyze associated risk factors., Methods: The participants were 95 patients, newborn to 18 years, who were admitted to the PICU. The instruments used were the Richmond Agitation Sedation Scale (RASS), and the Cornell Assessment of Pediatric Delirium. Data analysis was performed using the descriptive, x 2 test, t-test, and logistic regression analyses., Results: The incidence of delirium in children admitted to the PICU was 42.1%. There were significant differences according to age ( x 2 =14.10, p =.007), admission type ( x 2 =7.40, p =.007), use of physical restraints ( x 2 =26.11, p <.001), RASS score ( x 2 =14.80, p =.001), need for oxygen ( x 2 =5.31, p =.021), use of a mechanical device ( x 2 =9.97, p =.041), feeding ( x 2 =7.85, p =.005), and the presence of familiar objects ( x 2 =29.21, p <.001). Factors associated with the diagnosis of delirium were the use of physical restraint (odds ratio [OR]=13.82, 95% confidence interval [CI]=4.16~45.95, p <.001) and the presence of familiar objects (OR=0.09, 95% CI=0.03~0.30, p =.002)., Conclusion: Periodic delirium assessments and intervention should be actively performed. The use of restraints should be minimized if possible. The caregiver should surround the child with familiar objects and ensure a friendly hospital environment that is appropriate for the child., Competing Interests: No existing or potential conflict of interest relevant to this article was reported., (Copyright © 2019 Korean Academy of Child Health Nursing.

Purpose: To develop and test the validity and reliability of the Korean version of the Family Management Measure (Korean FaMM) to assess applicability for families with children having chronic illnesses., Methods: The Korean FaMM was articulated through forward-backward translation methods. Internal consistency reliability, construct and criterion validity were calculated using PASW WIN (19.0) and AMOS (20.0). Survey data were collected from 341 mothers of children suffering from chronic disease enrolled in a university hospital in Seoul, South Korea., Results: The Korean version of FaMM showed reliable internal consistency with Cronbach's alpha for the total scale of .69-.91. Factor loadings of the 53 items on the six sub-scales ranged from 0.28-0.84. The model of six subscales for the Korean FaMM was validated by expiratory and confirmatory factor analysis (χ²<.001, RMR<.05, GFI, AGFI, NFI, NNFI>.08). Criterion validity compared to the Parental Stress Index (PSI) showed significant correlation., Conclusion: The findings of this study demonstrate that the Korean FaMM showed satisfactory construct and criterion validity and reliability. It is useful to measure Korean family's management style with their children who have a chronic illness.

Background/aims: The role of dietary risk factors in colorectal carcinogenesis remains unclear. We investigated the association between dietary intakes and colorectal adenomas who visited a health promotion center for a routine health check-up colonoscopy., Methods: We conducted a retrospective case-control study using data from individuals who had colonoscopy at Seoul National University Hospital Healthcare System Gangnam Center from October 2003 to December 2007. The subjects were 242 patients (162 males and 80 females) with histopathologically confirmed colorectal adenoma, and 464 (272 males and 192 females) controls. Dietary data were obtained via 24 hour dietary recall, assisted by a registered dietitian. The student's t-test and the chi-square test were performed for the statistical comparison of means and proportions among groups. Multivariate analyses using logistic regression were performed to assess the relation between dietary intake and colorectal adenoma., Results: The total average energy intake of the patients (male: 2,407.5±429.2 kcal, female: 1,901.3±316.9 kcal) was higher than the controls (male: 2,249.6±430.4 kcal, female: 1,752.4±275.0 kcal; p=0.001). High energy intake (male: OR=4.13, 95% CI=1.70-10.05, p=0.002; female: OR=4.00, 95% CI=1.51-10.61, p=0.005) and animal protein intake (male: OR=3.97, 95% CI=1.66-9.49, p=0.002; female: OR=5.76, 95% CI=1.99-16.169, p=0.001) were found to be associated with the risk of colorectal adenoma after adjusting for confounders such as age, BMI, waist circumference, metabolic syndrome and smoking., Conclusions: In summary, high energy intake and animal protein were associated with colorectal adenoma.

Background/aims: Clinical manifestations of intestinal yersiniosis include enterocolitis, mesenteric adenitis, and terminal ileitis presenting with fever, right lower quadrant pain, and leukocytosis. According to a previous Korean study in 1997, Yersinia was revealed in two among 15 adult patients with mesenteric adenitis (13%). However, recent reports on the prevalence of Yersinia infection in adult patients are few. The aim of this study was to investigate the prevalence of Yersinia infection in adult patients with acute right lower quadrant pain., Methods: Adult patients (>18 years) who visited Eulji medical center, due to acute right lower quadrant pain were enrolled prospectively from December 2007 to July 2009. Abdominal CT, stool culture, serologic test for Yersinia, and Widal test were performed., Results: Among 115 patients, 5 patients were excluded due to positive Widal test or salmonella culture. In 110 patients, abdominal CT showed right colitis in 20 (18.2%), terminal ileitis in 16 (14.5%), mesenteric adenitis in 13 (11.8%), acute appendicitis in 10 (9.1%), acute diverticulitis in 7 (6.4%), non specific mucosal edema in 36 (32.7%) and no specific lesion in 8 (7.3%). Two (1.8%) of the 110 patients had antibodies to Yersinia. One patient showed acute enteritis and the other patient was diagnosed with acute appendicitis and underwent appendectomy. No Yersinia species were grown on stool or tissue culture., Conclusions: Nowadays, among adult Korean patients presenting with acute right lower quadrant pain, there have been few incidences of Yersinia infection.

Purpose: The purpose of this study was to develop and evaluate a Korean questionnaire to measure resilience in children with chronic illness., Methods: Item construction was drawn from an extensive review of the literature, existing questionnaires and interviews with parents. Content validity was tested by experts. To further refine the questionnaire and test its reliability and validity, data were collected from the 202 children with asthma, diabetes mellitus or nephrotic syndrome. Corrected items were used to total correlation coefficient and test-retest reliability. Questionnaire testing was conducted using factor analysis, Cronbach's alpha, and correlation coefficients. Validity of the questionnaire was tested using internal consistency, construct validity, and criterion-related validity., Results: Components of the questionnaire were in three domains; interpersonal characteristics, characteristics of coping, and intrapersonal characteristics. Factor analysis is showed five factors; positive self-understanding, self-reliance, resourcefulness, perception of positive family relationships, and intimacy. The questionnaire showed a high internal consistency. A significant positive correlation with the Numerical Rating Score and negative correlation with the Child Depression Inventory support the validity of the questionnaire., Conclusion: This instrument demonstrated high reliability and validity. Therefore, this instrument can contribute to the evaluation of resilience of chronically ill children and to any subsequent intervention as well as to develop a theory for resilience.

Purpose: This study was done to investigate nurses' knowledge of, and compliance with the multidrug-resistant organism (MDRO) infection control guidelines., Methods: A survey questionnaire was developed based on the institutional and national guidelines and was administered to a convenience sample of 306 nurses in a university hospital., Results: The mean score for knowledge was 33.87 (percentage of correct answers: 82.61%). The percentages of correct answers for basic concepts, route of transmission, hand washing/protective devices and environment management were 74.27%, 94.29%, 92.90% and 75.54% respectively. The mean compliance score was 4.15 (range: 1-5). The compliance scores for education, communication, contact precaution, disinfection, surveillance culture, and hand washing were 3.29, 4.05, 4.20, 4.50, 4.40 and 4.48 respectively. Nurses indicated "lack of time (30.06%)", "lack of means (10.78%)" and "lack of knowledge (9.48%)" as reasons for noncompliance., Conclusion: While most educational programs have focused on hand washing or use of protective devices to prevent transmission of MDRO in acute care settings, hospital nurses' knowledge of the basic concepts of MDRO and environmental management has remained insufficient. Nurses are relatively non-compliant to the guidelines in the areas of education (staff, patient, family) and communication. Comprehensive educational programs are needed to decrease hospital infection rates and to improve the health of patients.

Hepatocellular carcinoma (HCC) rarely invades the gastrointestinal (GI) tract. It occurs in 0.7% to 2% of clinical HCC cases. Moreover, gastric invasion with GI hemorrhage via peritoneal seeding is very rare. We report the case of 67-year-old woman who had a history of HCC rupture and was admitted due to left upper quadrant abdominal pain. The patient was diagnosed with three omental metastatic masses and underwent hepatic segmentectomy and omental tumorectomy. Two months later, the patient had massive melena, and an esophagogastroduodenoscopy showed very large ulcerated friable mass on the gastric body. The histology was consistent with the diagnosis of metastatic HCC. The patient died from persistent GI hemorrhage 93 days after the admission. This case illustrates the very rare event of peritoneal seeding of a ruptured HCC causing direct invasion of the stomach, followed by GI hemorrhage.

Mucinous (colloid) carcinoma is defined as pools of stromal extracellular mucin containing scanty, floating carcinoma cells. It is a well-defined entity in breast or large bowel. However, mucinous noncystic carcinoma of the pancreas (MNCC) is uncommon, comprising between 1% and 3% of all carcinomas of the pancreas. In the past, MNCC generally had been categorized together with ordinary ductal adenocarcinoma or misdiagnosed as mucinous cystadenocarcinoma or signet-ring cell carcinoma. The new WHO classification lists MNCC as a variant of ductal adenocarcinoma. Herein, we report a 32-year-old woman with incidentally found pancreatic body mass who underwent subtotal pancreatectomy. She was diagnosed as MNCC histologically.

Majority of malignant neoplasms arising from the extrahepatic bile duct are adenocarcinomas. Carcinoid tumors at this site are extremely rare. We report a 67-year-old woman with malignant carcinoid tumor of the common bile duct. She presented with obstructive jaundice of 1 week's duration. Abdominal CT and ERCP revealed a common bile duct mass. She underwent Whipple's operation and was diagnosed as malignant carcinoid tumor histologically and immunohistochemically.

Background/aims: Hedgehog protein is an essential molecule for gastrointestinal tract development, and disruption of hedgehog signaling pathway is linked to some gastrointestinal tumorigenesis. Here, we performed hedgehog immunostaining in periampullary cancer to evaluate the differences according to the location type of cancer and the differentiation of adenocarcinoma., Methods: We retrieved surgical specimens from 43 periampullary cancer patients (15 ampulla of Vater cancer, 12 distal common bile duct cancer, 13 pancreatic head cancer, and 3 combined ampulla of Vater/bile duct cancer). Immunohistochemical stain was performed in both normal and cancerous tissue portions of each case using Sonic hedgehog (H-160) rabbit polyclonal antibody. Immunohistochemical stain results were grouped into three groups according to the percentage of positive cytoplasmic stain in tumor volume (unstained: <5%, weakly stained: 5-50%, and strongly stained: >50%)., Results: All of the normal tissue revealed negative immunohistochemical stain while cancerous tissue revealed positivity in 95.3% (41/43 cases). Strongly stained cases were more frequently seen in ampulla of Vater cancers (13/15) and in combined ampulla of Vater/bile duct cancers (3/3) than in distal common bile duct cancers (4/12) and in pancreatic head cancers (3/13) (p=0.002). In addition, strongly stained cases were more frequently seen in well-differentiated adenocarcinoma than the others (p<0.001)., Conclusions: Most of the periampullary cancers show hedgehog protein expression. In addition, hedgehog protein immunostainings shows stronger expression in ampulla of Vater cancers and in well-differentiated adenocarcinoma.

Background/aims: Exclusion of liver disease from other causes such as autoimmune hepatitis is necessary for diagnosis of nonalcoholic fatty liver disease (NAFLD). However, there has been no study on the prevalence and significance of autoantibodies in the patients with clinically suspected NAFLD in Korea, where hepatitis B is endemic and autoimmune hepatitis is relatively uncommon., Methods: We prospectively tested for anti-nuclear antibody (ANA), anti-smooth muscle antibody (ASMA), and anti-mitochondrial antibody (AMA) in 135 serially enrolled patients with suspected NAFLD. We compared the clinical characteristics and biochemical indices of the ANA-positive or ASMA-positive group with those of the autoantibody-negative group., Results: Sixteen patients (11.8%) had serum autoantibodies; there was ANA in 8 patients (5.9%), ASMA in 7 (5.1%), and AMA in 2 (1.5%). Both ANA and AMA were positive in one patient. The ANA-positive or ASMA-positive group showed an older age (49.5+/-13.0 vs. 42.0+/-10.9 years, respectively, P=0.018) and higher levels of serum globulin (3.1+/-0.4 vs. 2.9+/-0.4 g/dL, respectively, P=0.037), compared with the autoantibody-negative group. Two cases with positive ANA or ASMA fulfilled the diagnostic criteria for probable autoimmune hepatitis and two cases with positive AMA were suspected as primary biliary cirrhosis., Conclusions: These findings suggest that autoantibodies could be found in some patients with suspected NAFLD in Korea, AMA-positivity or ASMA-positivity could be associated with old age and high serum globulin, and some of the autoantibody-positive cases could be diagnosed as autoimmune hepatitis or primary biliary cirrhosis. Further studies are necessary to clarify the clinical significance of autoantibody positivity in those patients.

Purpose: The purposes of this study were to describe the relationship between depression and resilience and to identify variables associated with depression among children with nephrotic syndrome., Method: Data was collected from 45 children who were registered at one hospital in Seoul. The criteria for sample selection were 10 to 15 year-old children who were diagnosed at least 6 month prior. The instruments included a self-reported questionnaire on resilience by Kim, CDI by Beck, and MBRI by Kwak. Descriptive, Pearson correlation and multiple regression analyses were done., Result: The mean score of depression was 11.44 (range:0-54) and resilience was 97.47 (range:32-128). There were significant positive relationships between depression and age (r=0.302, p<.005) and academic achievement (r=-0.318, p<.005). In addition, negative relationships between depression and maternal attitude (r=-0.412, p<.001) and resilience (r=-0.649, p<.001) occurred. The results of multiple regression analysis showed that maternal behavior (beta=-0.421, p<.005) and resilience (beta=-0.639, p<.001) were related to depression., Conclusion: Children with higher resilience and with an affectionate mother were less depressed. Thus, it is important to identify strengths of children and help them to increase resilience and implement parenting and counseling programs for parents' of these children. Similar studies with children with other chronic illnesses are needed.

Serous cystadenoma of the pancreas is a rare disease and is usually benign. Mucinous cystadenoma, another cystic neoplasm of the pancreas, has a malignant potential. Serous cystadenoma is usually composed of many small cysts lined by small, cuboidal or flattened cells containing abundant glycogen. With the finding of endoscopic retrograde pancreatography, a communication between the cyst and pancreatic duct is observed occasionally in the mucinous cystadenoma, but rarely in the case of serous cystadenoma of the pancreas. We experienced a case of serous cystadenoma of the pancreas that had a communication between a cyst and the pancreatic duct.

Mesenchymal hamartoma of the liver (MHL) is a rare benign tumor usually found in childhood, especially during the first two years. MHL is extremely rare in adults. Most reported cases present with a slow growing abdominal mass. It is thought to be a developmental anomaly and consists of bile ducts, hepatocytes and mesenchymal tissue. We report a case of mesenchymal hamartoma of the liver in an adult male with a brief review of the literature.
