OBJECTIVES: Refugees from North Korea are at risk of a range of mental health problems, posing urgent problems to their care. A review of research on mental health prevalence and services can indicate directions for further study. METHODS: The authors administered a Delphi survey to 16 professionals who are working for North Korean refugees, including professors and field workers. The collected data was analyzed by descriptive statistics including mean and standard deviation and verified with content validity ratio. RESULTS: The results are as follows: 1) The most serious problem in the research area is the importance of quantitative research rather than qualitative for North Korean refugees, who are often very negative and uncooperative with questionnaires. 2) There is a great need to develop competence of mental health professionals who are working for North Korean refugees. 3) Most participants agreed to the necessity of longitudinal study to define the factors facilitating successful adaptation among North Korean refugees. CONCLUSION: The following are our recommendations: 1) Appropriate measurements for North Korean refugees need to be developed reflecting their uniqueness. 2) Research of North Koreans has inherent selection bias. 3) It is essential to provide primary education on mental health to North Korean refugees.

PURPOSE: To investigate accommodation and progress of patients who showed myopia on manifest refraction in the early postoperative period after LASEK. METHODS: Forty-one eyes were included in the present study which had undergone LASEK surgery from February to March 2012. Seven eyes showed myopia over -0.25 D on manifest refraction at 1 month postoperatively, but showed decreased amount of myopia at 2 months postoperatively and were classified as group 1. The other 34 eyes were classified as group 2. The differences between cycloplegic and manifest refraction (CRSE-MRSE) were defined as the amount of latent accommodation and compared between the 2 groups. RESULTS: Amount of latent accommodation was 0.179 +/- 0.426 D in group 1 (7 eyes), 0.265 +/- 0.303 D in group 2 (34 eyes) preoperatively, 1.286 +/- 0.664 D in group 1, 0.368 +/- 0.536 D in group 2 at 1 month postoperatively, and 0.500 +/- 0.520 D in group 1, and 0.489 +/- 0.546 D in group 2 at 2 months postoperatively. The amount of latent accommodation in group 1 was significantly greater than that of group 2 one month postoperatively. As the amount of latent accommodation decreased, the amount of myopic shift decreased gradually over 2 months in group 1 after surgery. CONCLUSIONS: Transient myopic shift due to increased latent accommodation was observed in several patients one month postoperatively and the amount of myopic shift decreased with time without treatment. Thus, surgeons should consider cycloplegic refraction when planning treatment for patients with myopic regression.

Epidural abscess is a rare complication of epidural catheterization. Moreover, the early diagnosis of abscess may be difficult because of nonspecific symptoms and underlying painful disorder. It's outcome is strongly associated with the level of neurologic function at the time of diagnosis. We report the case of a cancer patient with diabetes mellitus, who developed an epidural abscess after 90 days of continuous epidural catheterization. In this case, the patient had no other neurologic symptom except for a tingling sensation in both legs, which recovered fully after surgery. This case demonstrates that the early diagnosis of epidural abscess and prompt surgical procedures are important, and can result in a good neurologic outcome.

Purpose: This study aimed to examine the differences in COVID-19 work-related characteristics, workload, anxiety, stress, and burnout between nurses working in the COVID-19 designated units and those in the general units caring for both COVID-19 and non-COVID-19 patients and to identify factors related to burnout in these two nurse groups. Methods: The study was conducted using data from 192 nurses in the COVID-19 designated units and 340 nurses in the general units from two general hospitals. The data were collected using self-report, structured questionnaires.Independent t-test, chi-squared test, and logistic regression analysis were performed. Results: There were no significant differences observed in workload and burnout between the two groups. For nurses in the general units, workload, stress, adequacy of the number of patients assigned, and the experience of temporary, floating staff were significant factors associated with burnout, while only clinical experience in the current unit was a significant factor among those in the COVID-19 units. Conclusion Findings indicate significant differences in factors related to burnout between the two nurse groups. Thus, substantial support and strategies tailored to the working environments of each nursing unit are required to prevent burnout among nurses caring for COVID-19 patients.

OBJECTIVE: To evaluate the effect of hyaluronidase in patients with failed back surgery syndrome (FBSS) treated with interlaminar lumbar epidural injection (ILEI). METHOD: Sixty patients suffering from severe low back pain and sciatica were randomly allocated into three groups. Group T received ILEI with 2 ml triamcinolone 40 mg/ml and 5 ml bupivacaine 0.25%. Group H received ILEI with 1500 IU hyaluronidase and 5 ml bupivacaine 0.25%. Group TH received interlaminar lumbar epidural injection (ILEI) with 1500 IU hyaluronidase, 2 ml triamcinolone 40 mg/ml and 5 ml bupivacaine 0.25%. The effect was evaluated using Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) at pre-injection, 2 weeks, 6 weeks and 12 weeks after ILEI. RESULTS: After 2 weeks and after 6 weeks, patients in both Group T and Group TH had significant effectiveness more than Group H in decrease of VAS and ODI. After 12 weeks, only patients in Group TH had significant effectiveness in decrease of VAS and ODI (p<0.05). In every period, Group TH had the most effectivess in decrease of VAS and ODI after ILEI. CONCLUSION: ILEI for FBSS with triamcinolone and hyaluronidase is considered to have more long term effectiveness to reduce pain and improve function after ILEI than injection with triamcinolone alone or hyaluronidase alone.

PURPOSE: Both under-nutrition and obesity may be associated with severity of viral infection. We investigated the association of obesity with clinical factors and the severity of acute bronchiolitis in infants. METHODS: We reviewed 740 infants younger than 1 year of age who were admitted with the first episode of acute bronchiolitis between 2010 and 2013. Subjects were classified into 3 groups according to the weight-for-length Z-score. RESULTS: Younger age (3.6+/-2.6 months) was more frequent in the obesity group (P<0.001). Infants aged < or =6 months (90%) dominantly included in the obesity group. Logistic regression showed that age (younger than 3 months) was independently associated with the overweight and obesity groups with acute bronchiolitis in infants (odds ratio [OR], 1.77; P=0.001 for overweight; OR, 4.67; P<0.001 for obesity). Moreover, the obesity group was associated with an increased risk of chest retraction, hypoxia, respiratory syncytial virus detection, length of stay (more than 5 days), and need for oxygen supplement. These factors tended to increase from the overweight group toward the obesity group. CONCLUSION: Younger than 3 months of age was a risk factor for developing worse clinical course in overweight and obesity groups with acute bronchiolitis in infants. Careful attention should be paid to the clinical course of younger obese infants with acute bronchiolitis.

Objective: We aimed to evaluate the clinical and imaging factors associated with hemorrhagic complications and patient discomfort following ultrasound (US)-guided breast biopsy. Materials and Methods: We prospectively enrolled 94 patients who were referred to our hospital between June 2022 and December 2022 for US-guided breast biopsy. After obtaining informed consent, two breast radiologists independently performed US-guided breast biopsy and evaluated the imaging findings. A hemorrhagic complication was defined as the presence of bleeding or hematoma on US. The patients rated symptoms of pain, febrile sensation, swelling at the biopsy site, and dyspnea immediately, 20 minutes, and 2 weeks after the procedure on a visual analog scale, with 0 for none and 10 for the most severe symptoms. Additional details recorded included those of nausea, vomiting, bleeding, bruising, and overall satisfaction score. We compared the clinical symptoms, imaging characteristics, and procedural features between patients with and those without hemorrhagic complications. Results: Of 94 patients, 7 (7%) developed hemorrhagic complications, while 87 (93%) did not. The complication resolved with 20 minutes of manual compression, and no further intervention was required. Vascularity on Doppler examination (P = 0.008), needle type (P = 0.043), and lesion location (P < 0.001) were significantly different between the groups. Patients with hemorrhagic complications reported more frequent nausea or vomiting than those without hemorrhagic complications (29% [2/7] vs. 2% [2/87], respectively; P= 0.027). The overall satisfaction scores did not differ between the two groups (P= 0.396). After 2 weeks, all symptoms subsided, except bruising (50% 2/4 in the complication group and 25% [16/65] in the no-complication group). Conclusion US-guided breast biopsy is a safe procedure with a low complication rate. Radiologists should be aware of hemorrhagic complications, patient discomfort, and overall satisfaction related to this procedure.
