Résumé

OBJECTIVE: The policy to judge the level of emergency (emergent vs non-emergent) based on Korean Triage and Acuity Scale (KTAS) has been introduced by government to control the flow of emergency patients. The purpose of this study is to identify the variables expected to affect the disposition and to compare the relative importance of the variables. And we also evaluate the validity of the policy to judge the level of emergency based on KTAS. METHODS: We enrolled a total of 29,865 patients who visited a Wide Regional Emergency Center in Busan from Jan 2016 to Dec 2016. Data of those patients were extracted from National Emergency Department Information System (NEDIS) and analysed retrospectively. We determined disposition as the outcome variable. We evaluated the relationship between disposition and visit time, visit mode (firehouse ambulance, inter-facility transfer and self-transport), level of emergency based on KTAS, cause of morbidity. And we also evaluated general and conditional dominances of those variables to compare their relative importance each other. RESULTS: The disposition of the patients was discharge to home (53.5%), general ward admission (30.3%), intensive care unit admission (11.6%), and inter-facility transfer (4.8%). In the univariate analysis, age, gender, visit time, visit mode, cause of morbidity, KTAS level had a significant effect on the disposition. All variables that had a significant effect on univariate analysis also had a significant effect on disposition in multivariate analysis. As a result of dominance analysis, visit mode was the most important variable in both general dominance and conditional dominance. However, if KTAS was devided into 5 levels, it was the most important variable. CONCLUSION: Level of emergency based on KTAS was significantly effective on patient disposition, however it was relatively less important compared to the visit mode. If the visit mode is reflected in the triage system, triage accuracy is expected to be improved. And it also can be a good option to construct triage system based on 5 level KTAS.

Résumé

Cytomegalovirus (CMV) infection is an important cause of morbidity and mortality among transplant recipients. The first line standard therapy for CMV pneumonia is treatment with a combination of ganciclovir and immunoglobulin. Nevertheless, the mortality of CMV pneumonia is 30~70%. Leflunomide has been recently reported to have novel anti-CMV activity by inhibiting viron assembly. It is also cheaper and is more easily given orally as compared to ganciclovir. We report here on an allogenic stem cell transplant recipient who developed CMV pneumonia that was refractory to ganciclovir and immunoglobulin. The patient was successfully treated with a combination of leflunomide and ganciclovir.

Résumé

The authors present a case of giant serpentine aneurysm (a partially thrombosed aneurysm containing tortuous vascular channels with a separate entrance and outflow pathway). Giant serpentine aneurysms form a subgroup of giant intracranial aneurysms, distinct from saccular and fusiform varieties, and in this case, too, the clinical presentation and radiographic features of CT, MR imaging and angiography were distinct.

Résumé

Malignant rhabdoid tumor (MRT) is a rare but distinctive neoplasm of unknown histogenesis, occurring primarily in children. It has a characteristic histologic pattern and aggressive clinical behavior, and was originally thought to be a malignant sarcomatous variant of Wilms tumor; numerous cases of MRT arising from extrarenal sites have, however, been reported. We describe the radiologic findings of two cases of malignant extrarenal rhabdoid tumor that arose in the pelvic paravertebral region of two children. Both were confirmed by surgical excision and pathologic examination.

Résumé

BACKGROUND: Bronchial asthma is a clinical syndrome characterized by reversiblity of airway obstruction. however, many asthma patients have evidence of residual airway obstruction. It has become evident that the repair of chronic inflammatory process can lead to various irreversible changes. It is generally accepted that the most common cause for change is cigarette smoking but it is controversial whether asthma progresses to emphysema. High resolution computed tomography (HRCT) is more sensitive and more accurate than chest plain films in determining the type and extent of emphysema. This study was carried out to determine whether asthma can be a cause of emphysema without the effect of cigarette smoking and to evaluate clinical characterics in asthma patients with emphysema. METHODS: We studied 58 asthmatic patients with reversible airway obstruction and evaluated the presence of emphysema using HRCT and pulmonary function test. According to HRCT findings, they were divided into 2 groups: Asthma patients with and without emphysema. RESULTS: Of the 58 patients, 7 were judged to have emphysema. (1) 6 asthma patients with emphysema were smokers, but one patient was nonsmoker. (2) Highly significant differences between patients with and without emphysema were found in cigarette smoking (p<0.01), smoking consumption (p<0.01). (3) There was no significant differences in the duration of asthma, age or sex between patients with and without emphysema. (4) There was no significant differences in FEV1 (%), FEV1/FVC (%), diffusing capacity for carbon monoxide (DLco) (%), DLco/alveolar volume between patients with and without emphysema (5) Differences between asthma patients without emphysema and those with emphysema were found to be significant in bronchial wall thickening (p<0.05) and in total Ig E (p=0.07). CONCLUSION: These results indicate that smoking is a main factor to cause emphysema in the patient with asthma.

Résumé

Our purpose was to study the correlation between elevated maternal serum alpha-fetoprotein(MSAFP) or human chorionic gonadotropin(HCG) levels and pregnancy-induced hypertension (PIH), preeclampsia, preterm delivery. MSAFP and HCG levels were measured in stored second-trimester(14~22 weeks) serum obtained from 510 women. The criteria for patients with unexplained MSAFP elevations were a MSAFP level 2.5 or greater multiples of the median(MoM) and HCG elevations were a HCG level 2.0 or greater multiples of the median(MoM) excluding multiple pregnancy, fetal malformation or death on ultra-sonography and molar pregnancy. In contrast, patients with MSAFP levels 0.5 to < 2.5 MoM, HCG levels < 2.0 MoM were served as controls. Women with elevated HCG levels had more significant association with PIH than control group(22.2 % versus 3.4 % ; p < .005). Elevated MSAFP was significantly associated with preeclampsia(7.7 % versus 1.1 % ; p < .05). But no significant differences were observed in the incidence of preterm delivery. We suggested elevated second-trimester MSAFP or HCG levels appear to be correlated with high risk for PIH and preeclampsia. So, These patients require careful monitoring with adequate obstetric managements.
