Background/Aims: This study aimed to determine changes in endoscopist-driven sedation practices 5 years after the first nationwide survey in 2014 by the Korean Society of Gastrointestinal Endoscopy (KSGE). Methods: A 59-item survey covering current practices was electronically mailed to all members of the KSGE in 2019. Results: In total, 955 (12.8%) out of 7,486 questionnaires were returned. A total of 738 (77.7%) out of 955 respondents attended dedicated sedation education programs. The American Society of Anesthesiologists class was recorded by 464 (51.2%) out of 907 respondents. The recording rate was higher in respondents who completed sedation education (p=0.014) and worked in general or tertiary hospitals (p<0.001). Compared to that reported in the previous survey, the reported use of propofol was higher in 2019. The respondents had higher satisfaction scores for propofol-based sedation compared with midazolam monotherapy (p<0.001). The rates of oxygen supplementation (p<0.001) and oxygen saturation level monitoring (p<0.001) during sedative endoscopy were higher in 2019 than in the previous survey. A total of 876 (98.4%) out of 890 respondents reported a separate recovery bay, and 615 (70.5%) out of 872 respondents reported that personnel were assigned solely to the recovery bay. Conclusions Endoscopist-driven sedation and monitoring practices in 2019 were significantly different than those in 2014. The respondents favored propofol-based sedation and utilized oxygen supplementation and monitoring of O2 saturation more frequently in 2019 than in 2014.

Purpose: This study aimed to examine associations among inner strength, mood status, symptom experience, and quality of life in women with lung cancer and to investigate whether inner strength has a moderating effect on these relationships. Methods: This study used a cross-sectional design to analyze 106 women with lung cancer in the National Cancer Center. A hierarchical regression analysis was conducted on the influence of quality of life. For the moderating effects, the Johnson–Neyman methods were applied using the SPSS PROCESS macro. Results: The significant factors of quality of life were inner strength, symptom experiences, total mood disturbance, accounting for 70.7% of the variance. Inner strength had a moderating effect on the relationship between total mood disturbance and quality of life. This means that when women have higher inner strength, there is a significantly less negative effect of total mood disturbance on quality of life. Conclusion Female patients with lung cancer who experienced inner strength can improve the quality of life as well as reduce the negative impact of mood status on the quality of life. Therefore, these findings support the theory of inner strength and provide nurses with an opportunity to foster the development of this theory in female cancer survivors.

The methylglyoxal (MGO) trapping constituents from Malus baccata L. were investigated using incubation of MGO and crude extract under physiological conditions followed by HPLC analysis. The peak areas of MGO trapping compounds decreased, and their chemical structures were identified by HPLC-ESI/MS. Sieboldin was identified as a major active molecule representing MGO-trapping activity of the crude extract. After reaction of sieboldin and MGO, remaining MGO was calculated by microplate assay method using imine (Schiff base) formation of 2,4-dinitrophenylhydrazine (DNPH) and aldehyde group. After 4 h incubation, sieboldin trapped over 43.8% MGO at a concentration of 0.33 mM and showed MGO scavenging activity with an RC 50 value of 0.88 mM for the incubation of 30 min under physiological conditions. It was also confirmed that sieboldin inhibited the production of advanced glycation end products (AGE) produced by bovine serum albumins (BSA)/MGO. Additionally, MGO trapping mechanism of sieboldin was more specifically identified by 1 H-, 13 C-, 2D NMR and, confirm to be attached to the position of C-3' (or 5').

PURPOSE: The purpose of this study is to determine factors affecting happiness of adolescents who attended community child centers. METHODS: We surveyed 154 adolescents attending a community child center in P City with a structured self-report questionnaire from October 3 to October 15, 2016. Data was analyzed by SPSS 18.0 descriptive statistics, t-test, ANOVA, Scheffé test, Pearson's correlation coefficients and stepwise multiple regression. RESULTS: The mean scores of family strength, friend support, teacher support, and happiness were 3.8±0.84, 3.8±0.98, 3.7±0.84 and 3.7±0.63. There were significant differences in happiness according to the subjects' number of close friends and duration of their stay at the community child center. There were a significant positive correlations among family strength, friend support, teacher support, and happiness. The most significant factors affecting happiness included friend support (β=.40) and peaceable family strength (β=.35). These variables explained 44% of the total variance in happiness. CONCLUSION: It is desirable to prepare and support measures to increase friends' support and family strength in order to improve happiness of adolescents attending community child centers. The findings suggest that it is necessary to develop nursing intervention programs to promote friend support and family strength.

PURPOSE: Diesel exhaust particles (DEPs) can induce and trigger airway hyperresponsiveness (AHR) and inflammation. The aim of this study was to investigate the effect of long-term DEP exposure on AHR, inflammation, lung fibrosis, and goblet cell hyperplasia in a mouse model. METHODS: BALB/c mice were exposed to DEPs 1 hour a day for 5 days a week for 3 months in a closed-system chamber attached to a ultrasonic nebulizer (low dose: 100 microg/m3 DEPs, high dose: 3 mg/m3 DEPs). The control group was exposed to saline. Enhanced pause was measured as an indicator of AHR. Animals were subjected to whole-body plethysmography and then sacrificed to determine the performance of bronchoalveolar lavage and histology. RESULTS: AHR was higher in the DEP group than in the control group, and higher in the high-dose DEP than in the low-dose DEP groups at 4, 8, and 12 weeks. The numbers of neutrophils and lymphocytes were higher in the high-dose DEP group than in the low-dose DEP group and control group at 4, 8, and 12 weeks. The levels of interleukin (IL)-5, IL-13, and interferon-gamma were higher in the low-dose DEP group than in the control group at 12 weeks. The level of IL-10 was higher in the high-dose DEP group than in the control group at 12 weeks. The level of vascular endothelial growth factor was higher in the low-dose and high-dose DEP groups than in the control group at 12 weeks. The level of IL-6 was higher in the low-dose DEP group than in the control group at 12 weeks. The level of transforming growth factor-beta was higher in the high-dose DEP group than in the control group at 4, 8, and 12 weeks. The collagen content and lung fibrosis in lung tissue was higher in the high-dose DEP group at 8 and 12 weeks. CONCLUSIONS: These results suggest that long-term DEP exposure may increase AHR, inflammation, lung fibrosis, and goblet cell hyperplasia in a mouse model.

Glomus tumors are benign neoplasms that are usually found in the subungual area, and are painful upon palpation. The typical treatment of choice is surgical excision. In rare cases, glomus tumors are observed as large-sized clusters, and are classified as atypical tumors known as glomangiomatosis. While surgical excision is the accepted standard of care, this proves difficult because of the tumors' large size and satellite lesions. We present the successful treatment of asymptomatic glomangiomatosis is situated on the left flank area by a combination of surgical excision and pulsed dye laser, which minimized the risk of scar formation.

OBJECTIVE: We investigated the features of endometrial hyperplasia with concurrent endometrial cancer that had been diagnosed by endometrial sampling. Further, we attempted to identify an accurate differential diagnostic method. METHODS: We retrospectively studied 125 patients who underwent a diagnostic endometrial biopsy or were diagnosed after the surgical treatment of other gynecological lesions, such as leiomyoma or polyps. Patients were diagnosed between January 2005 and December 2013 at Busan Paik Hospital. Clinical and histopathological characteristics were compared in patients who had atypical endometrial hyperplasia with and without concurrent endometrial cancer. RESULTS: The patients were grouped based on the final pathology reports. One hundred seventeen patients were diagnosed with endometrial hyperplasia and eight patients were diagnosed with endometrioid adenocarcinoma arising from atypical hyperplasia. Of the 26 patients who had been diagnosed with atypical endometrial hyperplasia by office-based endometrial biopsy, eight (30.8%) were subsequently diagnosed with endometrial cancer after they had undergone hysterectomy. The patients with endometrial cancer arising from endometrial hyperplasia were younger (39.1 vs. 47.2 years, P=0.0104) and more obese (body mass index 26.1+/-9.6 vs. 23.8+/-2.8 kg/m2, P=0.3560) than the patients with endometrial hyperplasia. The correlation rate between the pathology of the endometrial samples and the final diagnosis of endometrial hyperplasia was 67.3%. CONCLUSION: In patients with atypical endometrial hyperplasia, the detection of endometrial cancer before hysterectomy can decrease the risk of suboptimal treatment. The accuracy of endometrial sampling for the diagnosis of concurrent endometrial carcinoma was much lower than that for atypical endometrial hyperplasia. Therefore, concurrent endometrial carcinoma should be suspected and surgical intervention should be considered in young or obese patients who present with atypical endometrial hyperplasia.

PURPOSE: Birthmarks are commonly observed during neonatal period and its prevalence varies between races and countries. Most skin lesions are transient and not require medical treatment. But some birthmarks have potential medical significance and may be the first sign of systemic medical problems. We carried out a prospective study to determine the prevalence of birthmarks in Korean newborn infants. METHODS: From October 2012 to January 2013, 1,964 Korean newborn infants who were born in Cheil General Hospital, Kwandong University College of Medicine were evaluated for the presence of birthmarks within 48 hours after birth. RESULTS: Among 1,964 newborn infants, 980 (49.9%) infants were male and 984 (50.1%) were female. The most common pigmentary birthmark was Mongolian spot (97.1%), which was mostly presented on sacrogluteal area, and was followed by nevocellular nevi (0.8%), cafe-au-lait spot (0.8%), and sebaceous nevi (0.2%). Among vascular birthmarks, the most common lesion was salmon patch (30.8%), and followed by port-wine stain (0.2%) and hemangioma (0.2%). The common other lesions were sebaceous hyperplasia (37.4%), erythema toxicum neonatorum (10.2%), milia (4.1%), skin appendage (2.6%), anal dimple (1.2%), auricular pit (0.9%), miliaria (0.5%), aplasia cutis congenita (0.2%) in the order of frequency. CONCLUSION: We studied the prevalence of the birthmarks in Korean newborn infants. The most common pigmentary birth mark was mongolian spot, and the most common vascular birthmark was salmon patch in Korean newborn infants.

PURPOSE: Allergic diseases have been increased in Korea. The aim of this study was to investigate the changes of sensitization rate to inhalant allergens over 10 years in children with allergic diseases from a tertiary referral hospital. METHODS: Skin prick tests were done in total 2,225 children in 2000, 2005, and 2010. Changes of skin reactivity to 12 major inhalant allergens, including Tree pollen mixture I (Alder, Elm, Hazel, Poplar, Willow), Tree pollen mixture II (Beech, Birch, Oak, Plane tree), Dermatophagoides pteronyssinus, Dermatophagoides farina, Alternaria, cat dander, and dog dander were investigated. RESULTS: The sensitization rates to Tree pollen mixture I and II were increased as 5.0%, 6.8% in 2000, 8.5%, 9.8% in 2005, and 14.8%, 17.3% in 2010, respectively (trend P<0.001, P<0.001, respectively). And the sensitization rates to D. pteronyssinus cat dander and dog dander were changed as 55%, 4.8%, 4.8% in 2000, 62.2%, 11.9%, 28% in 2005, and 63.1%, 12.7%, 16.7% in 2010, respectively. The distribution of sensitized pollens was oak (12.8%), beech (12.4%), pine (10.3%), birch (10%), hazel (9.6%), alder (8%), elder (6.9%), elm (5.4%) in the study of 2010. When allergen/histamine ratio was compared, rates of strong sensitization over 4+ to tree pollen were increased. CONCLUSION: The sensitization rates to inhalant allergens were increased in children with asthma or allergic rhinitis from a tertiary referral hospital in Seoul over last 10 years. Especially, an increase in the degree of skin reactivity was observed in cat dander, dog dander, and tree pollens. The studies to investigate the etiology of this increase and prevention will be needed.
