PURPOSE: It is to report the efficacy and safety of an argon laser photocoagulation which was the treatment modality for retinopathy of prematurity. METHODS: From March 1996 to December 1999, on 69 prethreshold retinopathy of prematurity, they were series of observations following periods of two to five days, one week, two weeks, four weeks, three months and one year time respectively. RESULTS: We noticed the regressions in 84 prethreshold retinopathy of prematurity cases as well. CONCLUSIONS: The report emphasized the advantages of the argon laser photocoagulation which reduce the risk from a general anesthesia by applying a topical anesthesia, and the safety of using laser technique of convenience to apply and minimize the tissue damages of the lesions. It also described the preferable consequent results following the early treatment with divided applications on the prethreshold cases.

This study examined effect of preceptorship on clinical education of senior nursing students of Y. University in Seoul. Quasi-experimental study design was used. Sixty students of pre-test and 80 of post-test participated in this study. Competency scores of the students before the clinical education(pre-competency scores) were compared with the competency scores after the clinical education(post-competency scores), and teacher evaluation scores between preceptors and clinical the data from students with preceptors(experimental group, N=22) and with clinical instructors(comparative group, N=58) were also examined. Study results indicated that the total post-competency scores were higher compared to the total pre-competency scores, and the difference was statistically significant. Among 7 sub-domains, differences were all statistically significant in 6 sub-domains except "self-esteem" domain. Competency scores of the students who had clinical education with had clinical education from clinical instructors. But the difference between those scores was not statistically significant. However, students gave higher evaluation scores to preceptors than clinical instructors. This study concluded that preceptorship did not influence much on clinical education at this time yet. However it is expected that when preceptors adjust their new roles and function them in expert education. This study recommended that for the preceptors to increase their motivation to teach students and to accept their roles, systemic rewards are needed.

PURPOSE: The purpose of this study was to construct and test a structural equation model to investigate the risk factors of metabolic syndrome in rural women. METHODS: The raw data in this study was collected from the Korean Genome and Epidemiology Study supervised by the Korea Centers for Disease Control and Prevention from 2005 to 2010. The data included physical examinations and surveys of 1,125 women, who resided in three rural areas of South Korea. The structural model in this study was composed of five latent variables: depression, stress, social support, health behavior, and metabolic syndrome. The structural equation model was used to assess the relationships among the variables. RESULTS: The results of the study showed that depression and stress had direct effects on metabolic syndrome. Social support had a direct effect on health behavior and metabolic syndrome. Also, health behavior had a direct effect on metabolic syndrome. CONCLUSION: This study may serve as a guideline for interventions and strategies used to reduce metabolic syndrome in rural women.

PURPOSE: We evaluated the abdominal uttrasonographic findings of Salmonellosis. MATERIALS AND METHODS: This study included 64 patients who were confirmed as salmonellosis by blood culture. We retrospectively analyzed the abdominal ultrasonographic findings with particular attention to enlarged mesenteric lymph nodes(mesenteric lymphadenitis), thickening of bowel wall, especially terminal ileum and cecum(ileocecitis), hepatosplenomegaly, ascites, gallbladder wall thickening, and enlarged lymph nodes in porta hepatis. RESULTS: The 64 cases were observed as mesenteric lymph node enlargement(44 cases), wall thickening of the terminal ileum and cecum(36 cases), hepatomegaly and/or splenomegaly(42 cases), minimal ascites(8 cases), gallbladder wall thickening(6 cases), and enlarged lymph nodes in porta hepatis(4 cases). No abnormal finding was seen in 10 patients. CONCLUSION: The mesenteric lymph node enlargement, wall thickening of the terminal ileum and cecum, hepatomegaly and/or splenomegaly, minimal ascites, gallbladder wall thickening, and enlarged lymph nodes in porta hepatis are suggestive findings of salmonellosis on abdominal ultrasonography in patients with fever and acute abdomen.

PURPOSE: We attempted to evaluate the usefulness of Doppler sonography in the diagnosis of uterine vascular abnormality caused by previous D&E, and to report that transarterial embolization is an exceelent treatment modality. MATERIALS & METHODS: We analyzed gray-scale US, color/duplex Doppler US and angiographic findings inseven patients with radiologically proven uterine vascular abnormality. Two of the seven cases were pseudoaneurysms and five of the seven cases were AVMs. In one of the AVMs, two small pseudoaneurysms were combined. In all cases, transarterial embolizations using 3mm coil or/and gelfoam particles were performed. Follow-up US studies, including color Doppler US, were performed. RESULTS: On color/duplex Doppler sonography, two cases of pseudoaneurysm showed blood pools with turbulent arterial flow, and five cases of AVM showed asymmetrically increased vascularity, with variable high velocities composed of the pulsatie arterial flow, with ahigh diastoic component. On angiography, the former showed pseudoaneurysmal sacs, and the latter densely opacified vascular tangles. No more abnormal uterine bleeding was shown, following transarterial embolization in all cases. CONCLUSION: Color/duplex Doppler sonography was valuable in the diagnosis or treatment of abnormal uterine bleeding caused by uterine vascular abnormality such as acquired AVM or pseudoaneurysm.

PURPOSE: Colorectal cancer (CRC) has a high risk for postoperative thromboembolic complications such as venous thromboembolism (VTE) compared to other surgical diseases, but the relationship between VTE and CRC in Asian patients remains poorly understood. The present study examined the incidence of symptomatic VTE in Korean patients who underwent surgery for CRC. We also identified risk factors, incidence and survival rate for VTE in these patients. MATERIALS AND METHODS: The patients were identified from the CRC database treated from January 2011 to December 2012 in a single institution. These patients were classified into VTE and non-VTE groups, their demographic features were compared, and the factors which had significant effects on VTE and mortality between the two groups were analyzed. RESULTS: We analyzed retrospectively a total of 840 patients and the incidence of VTE was 3.7% (31 patients) during the follow-up period (mean, 17.2 months). Histologic subtype (mucinous adenocarcinoma) and previous history of VTE affected the incidence of VTE on multivariate analysis. There was a statistically significant difference in survival rate between the VTE and non-VTE group, but VTE wasn't the factor affecting survival rate on multivariate analysis. Comparing differences in survival rate for each pathologic stage, there was only a significant difference in stage II patients. CONCLUSION: Among CRC patients after surgery, the incidence of VTE was approximately 3% within 1 year and development of VTE wasn't a significant risk factor for death in our study but these findings are not conclusive due to our small sample size.

Acute giant coronary aneurysm after Kawasaki disease (KD) is a catastrophic complication that can be fatal and very difficult to manage. However, no fixed consensus has been reached for the management of super-giant coronary aneurysms in the acute setting. Here, we report the successful management of young children with super-giant coronary aneurysms after KD. Based on our experience, hemodynamic stabilization to prevent further coronary dilation or rupture and strict anticoagulation to avoid thrombus formation are mandatory in the management of this condition.

Pyrolysis of tissue in a hypoxic environment can produce carbon monoxide. Peritoneal cavity is hypoxic during laparoscopic cholecystectomy by insufflation with 100% carbon dioxide, then, carbon monoxide is produced by electrocautery of tissue. To determine whether carbon monoxide was being absorbed in dangerous amounts to patients and operating room workers, blood was analyzed for carboxyhemoglobin in patients and their operators. Twenty-one patients undergoing this procedure, sampling the insufflation gas before, after use of electrocautery analyzed for carbon monoxide. Carbon monoxide was present in the peritoneal cavity, 5 min after use of electrocautery at a median concentration of 430 ppm(range 20~1000 ppm), and at the end of surgery at a median concentration of 174 ppm(range 10~720 ppm). This is well in excess of the 35 ppm upper limit for a 1-hr exposure set by the Environmental Protection Agency in U.S.A.. The patients carboxyhemoglobin concentrations(mean +/- SD) at the beginning, at the end and 3 hrs after surgery were 0.51+/-0.30%, 0.41%+/-0.28%, and 0.45%+/-0.74%, respectively. The operator's carboxyhemoglobin concentrations before and at the end of surgery were 1.12%+/-1.09% and 1.03%+/-1.03%, respectively. Although there was no evidence of significant absorption of carbon monoxide in these patients and operators, care should be taken to scavenge the gases produced by electrocautery of tissues to avoid operating room contamination during laparoscopic cholecystectomy.

BACKGROUND AND OBJECTIVES: This study is aimed at elucidating potential temporal associations between the occurrence of Kawasaki disease (KD) and various viral infections. SUBJECTS AND METHODS: We obtained monthly patterns of KD from the seventh nationwide survey and viral detection data from the Korea Centers for Disease Control and Prevention from 2009 to 2011 and evaluated temporal correlations between them for each month. The respiratory viruses detected using a multiplex real-time-polymerase chain reaction kit were influenza virus (A/H1N1, A/H3N2, A/H5N1, and B), adenovirus, parainfluenza virus (type 1, 2, 3), respiratory syncytial virus (type A, B), human rhinovirus, human coronavirus (OC43/229E, NL63), human bocavirus, and enterovirus. RESULTS: We obtained data from a total of 13031 patients who were treated for acute KD from 87 hospitals with pediatric residence programs. During this survey, KD showed highest overall incidence in summer and winter seasons and lowest incidence in February and October. We received viral detection data for a total of 14267 patients. Viral detection was highest during winter and spring seasons. The most commonly detected virus was human rhinovirus (32.6%), followed by influenza virus (26.8%). The monthly incidence of KD showed significant correlation with the monthly overall viral detection (p=0.022, r=0.382). In particular, human bocavirus and enterovirus have significant correlations with monthly patterns of KD occurrence (p=0.032 and p=0.007, respectively) and influenza virus correlated with KD occurrence with borderline significance (p=0.063). CONCLUSION: The temporal association between monthly occurrence of KD and viral detection suggests the etiologic importance of precedent infection in the development of KD.
