Purpose: The purpose of this study was to develop a Korean nursing work environment scale for critical care nurses (KNWES-CCN) and verify its validity and reliability. Methods: A total of 46 preliminary items were selected using content validity analysis of experts on 64 candidate items derived through literature reviews and in-depth interviews with critical care nurses. 535 critical care nurses from 21 hospitals responded to the preliminary questionnaire from February to March 2021. The collected data were analysed using construct, convergent and discriminant validities, and internal consistency and test-retest reliability. Results: The 23 items in 4 factors accounted for 55.6% of the total variance were identified through item analysis and exploratory factor analysis (EFA). EFA was performed with maximum likelihood method including direct oblimin method. In the confirmatory factor analysis, KNWES-CCN consisted of 21 items in 4 factors by deleting the items that were not meet the condition that the factor loading over .50 or the squared multiple correlation over .30. This model was considered to be suitable because it satisfied the fit index and acceptable criteria of the model [x2 =440.47 (p<.001), CMIN/DF=2.41, GFI=.86, SRMR=.06, RMSEA=.07, TLI=.90, CFI=.91]. The item total correlation values ranged form .32 to .73 and its internal consistency was Cronbach's ⍺=.92. The reliability of the test-retest correlation coefficient was .72 and the intra-class correlation coefficient was .83. Conclusion The KNWES-CCN showed good validity and reliability. Therefore, it is expected that the use of this scale would measure and improve nursing work environment for critical care nurses in Korea.

This study focused on the socialist camp's North Korean medical support and its effects on North Korean medical field from liberation to 1958. Except for the Soviet assistance from liberation to the Korean War, existing studies mainly have paid attention to the ‘autonomous’ growth of the North Korean medical field. The studies on the medical support of the Eastern European countries during the Korean War have only focused on one-sided support and neglected the interactions with the North Korean medical field. Failing in utilizing the materials produced in North Korea has led to the omission of detailed circumstances of providing support. Since the review of China's support and the North Korea-China medical exchanges has been concentrated in the period after the mid-1950s, the impacts of China's medical support on North Korea during the Korean War period and the post-war recovery period have not been taken into account. In terms of these limitations, this study examined the medical activities by the Socialist camp of the Eastern European countries in North Korea after the Korean War. The medical aid teams from Hungary, Romania, Bulgaria, Czechoslovakia, Poland, and East Germany that came to North Korea in the wake of the Korean War continued to stay in North Korea after the war to build hospitals and train medical personnel. In the hospitals operated by these countries, cooperative medical care with North Korean medical personnel and medical technology education were conducted. Moreover, medical teams from each country in North Korea held seminars and conferences and exchanged knowledge with the North Korean medical field staffs. These activities by the Socialist countries in North Korea provided the North Korean medical personnel with the opportunity to directly experience the medical technology of each country. China's support was crucial to North Korea's ‘rediscovery’ of Korean medicine in the mid-1950s. After the Korean War, North Korea began to apply the Chinese-Western medicine integration policy, which was performed in China at that time, to the North Korean health care field through China's medical support and exchanges. In other words, China's emphasis on Chinese medicine and the integration of the Chinese-Western medicine were presented as one of the directions for medical development of North Korea in the 1950s, and the experiences of China in this process convinced North Korea that Korean medicine policy was appropriate. The decision-makers of the North Korean medical policies, who returned to North Korea after studying abroad in China at that time, actively introduced the experiences from China and constantly sought to learn about them. This study identified that a variety of external stimuli had complex impacts on the North Korean medical field in the gap between ‘Soviet learning’ in the late 1940s and the ‘autonomous’ medical development since the 1960s. The North Korean medical field was formed not by the unilateral or dominant influences of a single nation but by the stimulation from many nations and the various interactions in the process.

Misoprostol is widely used in daily practice for induction of labor and cervical dilatation prior to intrauterine procedures, including dilatation and curettage or hysteroscopy. Anaphylactic shock to intravaginal misoprostol can occur not only in pregnant women, as reported in 2 previous cases, but also in a non-pregnant, perimenopausal woman, as in the case described herein. A 49-year-old woman received vaginal misoprostol for cervical ripening prior to hysteroscopic myomectomy and experienced anaphylactic shock. Two 400 μg doses of misoprostol 6 hours apart caused uncontrolled shaking and high fever followed by shock. In conclusion, the possibility of anaphylactic shock should be considered in patients with sudden hypotension following misoprostol administration. Prompt identification and management are crucial to prevent morbidity and mortality following an anaphylactic shock to misoprostol.

OBJECTIVE: Endometriosis is a common and recurring gynecologic disease which have afflicting females of reproductive age. We investigated the efficacy of long-term, post-operative use of dienogest for ovarian endometrioma. METHODS: We studied 203 patients who had undergone laparoscopic or robotic surgery for ovarian endometrioma, and were administrated dienogest 2 mg/day beginning in July of 2013, and continuing. We evaluated side effects of dienogest and ultrasonography was performed every 6 months to detect potential recurrence of endometrioma (2 cm) in these post-surgical patients. RESULTS: The follow-up observation periods were 30.2±20.9 months from surgery. The mean age was 34.1±7.2 years old. The mean diameter of pre-operative endometrioma was 5.6±3.0 cm2. One hundred eighty-two (89.7%) women received dienogest continuously for 12.0±7.1 months. Of the subjects, 21 (10.3%) patients discontinued dienogest at 2.4±1.0 months. The most common side effect when dienogest was discontinued was abnormal uterine bleeding. The occurrence rate of vaginal bleeding was 15.8%, a number which did not differ significantly in patients with/without post-operative gonadotropin releasing hormone agonist administration. The other side effects were gastrointestinal trouble including constipation, acne, headache, depression, hot flush, weight gain, and edema. However, no serious adverse events or side effects were documented and recurrent endometriomas were diagnosed in 3 patients (1.5%). CONCLUSION: The data indicates that dienogest was both tolerable and safe for long-term use as prophylaxis in an effort to obviate the recurrence of ovarian endometrioma post-operatively, as well as potential need for surgical re-intervention.

OBJECTIVE: Adenomyosis and endometriosis are relatively common gynecological diseases that exhibit many common features. This study identified gynecological and non-gynecological diseases that exhibited comorbidity with adenomyosis and endometriosis in Korean women. METHODS: We used Health Insurance Review and Assessment data from 2009 to 2011 and searched for adenomyosis and endometriosis (coded as N80.1 and D25 in International Classification of Disease, 10th revision [ICD-10], respectively). We selected records from patients who had independent disease occurrences in each year, and comorbidities were estimated using Fisher's exact test. We computed each year's similarities and combined 3 years' results using Fisher's P-value summation method. RESULTS: A total of 61,516 patients' data were collected during the study period. The prevalence of adenomyosis and endometriosis were similar each year: 12.4% and 9.3% in 2009, 12.5% and 9.4% in 2010 and 13.3% and 9.1% in 2011, respectively. Meta-analysis revealed that 31 ICD-10 codes were significantly related with adenomyosis, and 44 ICD-10 codes were related with endometriosis. Gynecological diseases, such as leiomyoma and benign ovarian tumor, were significantly related to adenomyosis and endometriosis. Non-gynecological diseases, such as anemia and hypercholesterolemia, were also related to adenomyosis and endometriosis. CONCLUSION: We must monitor for the presence of gynecological and non-gynecological diseases with co-morbidities during evaluations and follow-up of patients with adenomyosis or endometriosis.

The prevalence of periodontal disease was steadily increased. The best prevention methods for periodontal disease are teeth brushing and scaling. The purpose of this study was to investigate the status of scaling experience and related factors among some workers. Total 455 workers in 5 manufacturing companies in Gwangju were selected using convenience sampling method. General characteristics, work-related characteristics, oral health-related characteristics and scaling experience were collected by self-reported questionnaires. Chi-square tests, t-tests and multiple logistic regression analysis were performed to investigate the factors influencing the scaling experience using SPSS software. Statistical significance was defined as a p-value<0.05. The proportion of scaling experience during the past year was 47.0%. In simple analysis, age, current working position, number of oral disease, interest in oral health, use of secondary oral products, oral health screening use, oral health education experience and awareness of scaling inclusion in the National Health Insurance (NHI) coverage were associated with scaling experience. Finally, the odds ratios (ORs) for scaling experience were significantly higher in younger subjects (adjusted OR [aOR], 3.09; 95% confidence internal [CI], 1.60∼5.96), assistant manager (aOR, 2.68; 95% CI, 1.55∼4.63), subjects with high interest in oral health (aOR, 2.15; 95% CI, 1.02∼4.52), subjects with oral health screening use (aOR, 2.76; 95% CI, 1.50∼5.11) and awareness of scaling inclusion in the NHI coverage (aOR; 2.91, 95% CI, 1.80∼4.72) in multiple logistic regression analysis. Scaling experience was relatively low (47.0%). The related factors with scaling experience were age, working position, use of screening and awareness of scaling inclusion in the NHI coverage. Considering these factors will increase the utilization rate of scaling.

PURPOSE: This study aimed to identify multidimensional factors influencing burnout in intensive care unit(ICU) nurses. METHODS: A descriptive cross-sectional design was used. Data were collected during February 2016 from a convenience sample of 222 tertiary hospital ICU nurses and analyzed using t-test, ANOVA, correlation analysis, and multiple regression analysis. RESULTS: Burnout correlated positively with compassion fatigue (CF)(r=.37, p < .001), and negatively with compassion satisfaction (CS)(r=-.66, p < .001). The regression model explained 57% of the variance in burnout. For individual characteristics in the model, perceived health status (β=-.27, p < .001) and gender (β=.14, p=.028) were the most influential factors for ICU nurses' burnout. In the model with added work-related characteristics, nursing environment (β=-.22, p=.001), perceived health status (β=-.20, p=.001), and satisfaction with department (β=-.19, p=.007) were the most influential factors. Finally, for the model with psychological characteristics added, CS (β=-.56, p < .001) and CF (β=.35, p < .001) were the most influential factors. CONCLUSION: Results reveal that most ICU nurses have a moderate level of CF and a moderate to high level of CS and burnout, and that individual, work-related and psychological factors are relevant in ICU nurses' burnout. Programs or interventions to reduce burnout should be developed taking into account these multidimensional factors.

OBJECTIVES: This study aimed to evaluate the healing rate of non-surgical endodontic treatment between C-shaped and non-C-shaped mandibular second molars. MATERIALS AND METHODS: Clinical records and radiological images of patients who had undergone endodontic treatment on mandibular second molars between 2007 and 2014 were screened. The periapical index scoring system was applied to compare healing outcomes. Information about preoperative and postoperative factors as well as the demographic data of the patients was acquired and evaluated using chi-square and multinomial logistic regression tests. RESULTS: The total healing rate was 68.4%. Healing rates for the mandibular second molar were 70.9% in C-shaped canals (n = 79) and 66.6% in non-C-shaped ones (n = 117). The difference was not statistically significant. CONCLUSIONS: The presence of a C-shaped canal in the mandibular second molar did not have a significantly negative effect on healing after treatment. Instead, proper pulpal diagnosis and final restoration were indicated as having significantly greater influence on the healing outcomes of C-shaped and non-C-shaped canals, respectively.

Mucormycosis is an extremely rare but potentially life-threatening fungal infection. Mucormycosis of the gastrointestinal tract manifests with features similar to ischemic colitis. A 48-year-old man with end-stage renal disease due to diabetic nephropathy underwent deceased donor kidney transplantation. He complained of abdominal pain and distension on postoperative day 17. A computed tomography (CT) scan revealed symmetrical wall thickening of the ascending colon, which was consistent with ischemic colitis. However, a follow-up CT scan showed a localized wall-off colon perforation in the hepatic flexure and segmental mural gas in the ascending colon. Microscopic examination obtained from a surgical specimen demonstrated numerous fungal hyphae and spores in the mucosa and submucosa. A total colectomy was performed, but the patient died 36 days later due to multiple organ failure, despite antifungal agents. Clinicians should be informed about fungal infection, such as colonic mucormycosis mimicking ischemic colitis, in kidney transplant patients with diabetes mellitus, and treatment should be initiated at the earliest.

Charcoal can be used for preoperative localization of metastatic lymph nodes in the neck. Charcoal remains stable without causing foreign body reactions during as hort period. However, foreign body reactions may develop if charcoal is left in situ for more than 6 months. We reported a case of charcoal granuloma mimicking local recurrence on fluorodeoxyglucose-positron emission tomography/computed tomography and ultrasonography in a 47-year-old woman who had cervical lymph node dissection due to metastatic invasive ductal carcinoma of the breast.
