Purpose: This study evaluated the diagnostic performance of contrast-enhanced voiding ultrasonography (CeVUS) for detecting intrarenal reflux (IRR) and the correlation between CeVUS-detected IRR sites and photon defect sites in acute 99mTc-dimercaptosuccinic acid (DMSA) renal scans in pediatric patients. Methods: Fifty-four kidneys from 27 patients (20 males and seven females; mean age, 5.6±4.1 months) who underwent CeVUS and acute DMSA renal scans for recurrent urinary tract infection (UTIs) or pyelonephritis were included. Pediatric experts compared the results of CeVUS with acute DMSA renal scans. Results: Thirteen renal units (13/54, 24.1%) in 10 patients (nine males and one female; mean age, 6.3±3.7 months; age range, 0 to 13 months) showed vesicoureteral reflux and eight renal units (8/54, 14.8%) demonstrated IRR on CeVUS. Ten renal units in eight patients (six males and two females; mean age, 6.9±1.4 months; age range, 2 to 13 months) showed 19 photon defects on acute DMSA renal scans. Fifty-two renal units (96.3%) showed concordant results, and two renal units (3.7%) showed discordant results between CeVUS and acute DMSA renal scans. IRR accounted for 15/19 (78.9%) photon defects in eight renal units of seven patients using CeVUS. In a per-renal-unit analysis, the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of CeVUS were 80%, 100%, 100%, 95.7%, and 96.3%, respectively. Conclusion CeVUS showed good performance in detecting IRR, and the IRR sites detected by CeVUS closely correlated with photon defect sites in acute DMSA scans. CeVUS may play an important role in managing patients with recurrent UTIs or pyelonephritis with reduced radiation exposure.

Purpose: The purpose of this study was to identify factors influencing the performance of safe injection practices among nurses at general hospitals, in order to provide foundational data for developing strategies to improve the quality of injection practices in the future. Methods: This descriptive study was conducted with 153 nurses who were involved in injection practices. The data were collected from August to September 2024. Results: The most frequently performed type of injection by the participants was intravenous, and all types of injection practices were performed an average of 26.8±19.07 times per working day. The variable that most significantly influenced the performance of safe injection practices was knowledge of safe injection practices (β=.56, p<.001), which explained 36.7% of the variance. Experience with injection practice-related education (β=.27, p<.001) explained an additional 10.7% of variance, and organizational culture for infection control (β=.21, p<.001) explained 3.7% more. The total explanatory power of these variables on the performance of safe injection practices was 50.3% (F=52.35, p<.001). Conclusion Since both personal aspects, such as knowledge of safe injection practices and experience with injection practice-related education, and organizational aspects, such as organizational culture for infection control, simultaneously influenced the performance of safe injection practices among nurses at general hospitals, it is strongly recommended to develop and implement an integrated program for improvement. This program should combine strategies to enhance individual knowledge and positively transform the organizational culture for infection control, aiming for higher-quality execution of nursing duties, including injection practices.

PURPOSE: Because there are no significant differences of the clinical findings between the appendicitis and cecal diverticulitis, it is very difficult to make a correct diagnosis preoperatively and to choose a appropriate management intraoperatively. The purpose of this study is to investigate the clinical charateristics of right diveticulitis and to evaluate the appropriateness of surgical management. METHODS: We reviewed 45 cases of right colonic diverticulitis which underwent emergency operation under the impression of acute appendicitis during 10 years from January 1988 to December 1997. RESULTS: Of them, 38 cases were treated by diverticulectomy with appendectomy (Group I), and 7 cases were treated by resection (ileocecal resection or right hemicolectomy) (Group II). The male to female ratio was 4:1, and the mean age was 38.2 years. In Group I, all cases had a solitary inflamed cecal diverticulum. In group II, two cases had a solitary cecal diverticulitis, whereas five cases had multiple ones. Postoperative complications were found in 14 cases, but all of them were not significant. Postoperative Barium enema was performed in 22 cases of Group I, in two cases of Group II. In Group I, 8 cases had a residual diverticulum at postoperative Barium enema. In Group II, no residual diverticulum was shown. Follow-up study by Telephone was done at 16 cases, there were no symptomatic recurrences. CONCLUSIONS: In conclusion, when right colonic diverticulitis is found at the time of operation, surgical management is a safe treatment with low morbidity and low recurrence rate. Diverticulectomy with appendectomy is a safe surgical procedure for the uncomplicated diverticulitis. If diverticulitis is complicating, multiple or undistinguishable with malignancy, resection (ileocecal resection, right hemicolectomy) should be considered as a primary surgical treatment. Postoperative colon study is helpful, due to high incidence of residual diverticulum.

Objective: To establish and to promote the qualitative development of a housing service model in South Korea. Methods: The questionnaire was collected through the housing needs survey and the focus group interview on the mental health professions. We enrolled 365 subjects from 63 places (community conversion facilities, cohabitation, cohabitation families, hospitals, psychiatric nursing homes) to answer the questionnaires. Results: The survey result confirms the needs of people with a mental illness to be self-reliant, but it shows that the economic vulnerability is a hindrance. In addition, the most necessary factor for self-reliant living is to provide services that support daily living. Therefore, the study points out that a system that guarantees self-reliance must be added in order for the housing services to be distributed throughout local communities for the people with mental illness. Conclusion The study proposes the Seoul-type housing services model to replace the housing services that functions in a fragmented manner with the provision of an integrated services through a unified channel by establishing a housing support center (tentative name). This will ultimately help people with a mental illness to live a healthy life that meets their needs as community members.

BACKGROUND: Recently in Korea, the rate of addictive drug abuse is rapidly increasing in men on salary, housewives, and even in adolescents, who have been considered to be free from drugs, which presents a serious problem to the society. Especially, the habituation to gateway drug, such as cigarettes and alcohol, before 15 years old, would lead to the increased possibility of other drug abuse, including illicit drugs. Thereupon in this study, we intended toreview the effect of adolescents smoking an the drug abuse and deviated behaviors. METHODS: On September, 1997, randomly selected were 12 classes, an the basis of 2 classes per grade, from the two schools which was located each in Seoul and Buchean. And survey was dane on 610 students with non non-nominl, self-reported questionnaire. RESULTS: The rate of adolescent smoking was 28.1% in male students and had increasing tendency of "the higher the grades, the higher the smoking rate"(17.0% in the 1st gade, 31.5% in the 2nd grade, 35.9% in the 3rd grade). The smoking rate of female students was 12.3%. From the 2nd grade of middle school to the 2nd grade of high school was the critical period when the smoking habit was initiated in almost 90% of the students. The experiencing rates of drug abuse in studied subjects were as follows : drinking(79.0%), stimulants(4.8%), sedatives(4.1%), hypnotics(3.1%), glue sniffing(1.5%), butane gas(0.7%), marijuana/hemp(0.2%). They were higher in the smoking group than in the nansMoking group, showing statistical significances in most items except hypnotics and marijuana/hemp. Also simihr results were shown in deviated behaviors between the groups. CONCLUSIONS: With the concerted efforts of family, school, society and natian, we as family physicians should make efforts to delay and prevent adolescent's smoking, which is a gateway to drug abuse and deviated behaviors, and to increase people's recognition of health risks caused by smoking, and to provide proper program for adolescents to stop smoking.

PURPOSE: The aim of this study is to prove the association between potential fetal hypoxia and retinopathy of prematurity (ROP) development and absolute nucleated red blood cell (aNRBC) is used to evaluate it in premature infants without any hypoxic or ischemic history. METHODS: Medical records of 43 premature infants with ROP who were admitted to the neonatal intensive care unit at Wonkwang University Hospital from January 2004 to December 2014 were analyzed retrospectively. We excluded 15 infants who had a confounding medical condition that could have increased the aNRBC count. Finally, 28 premature infants affected by ROP were enrolled and compared with 28 pair-matched controls. The aNRBC counts at birth in these infants were compared. Statistical analysis was performed with a paired t-test for continuous data, and a Fisher's exact test for categorical data. P<0.05 was considered significant. RESULTS: There were no significant differences in perinatal characteristics such as gestational age (GA), birth weight (BWt), Apgar scores, premature rupture of membrane (>24 hours), prenatal betamethasone, surfactant or respiratory distress syndrome between the ROP and the control infants. In addition, neither group differed in major morbidities such as patent ductus arteriosus, periventricular leukomalacia, intraventricular hemorrhage (> or =Grade 2), or bronchopulmonary dysplasia. Regardless of the severity of ROP, the aNRBC counts at birth in premature infants with ROP were not higher than in the control infants. CONCLUSION: The aNRBC counts at birth may not be related directly to the development of ROP.
