The utilization of CT-guided fine needle aspiration biopsy of bone has been the subject of considerable interest, since the introduction of the CT scanning. The CT-guided needle biopsy of 11 consecutive patients with avariety of "Etiology Unknown Spinal Disorders" resulted in a 100% yield of positive tissue diagnosis without significant complicaitons. The main advantage of CT guidance is the continuous direct observation of the needletip position in relation to the target volume, the more precise sampling from smaller and deeper lesion is another advantage. We are confident that localization of pathology by CT is the most accurate method for perform ingbiopses, and thus replaces the conventional ways of approaches and this could be utilized on the other organbiopsy in the future.

BACKGROUND: Intravenous catheter-related complication among the hospitalized patients has been increasing recently in Korea, since many hospitals has tried to save expenses by replacing the foreign-made catheter with domestic-made intravenous catheter. We studied the incidence rate of catheter-related complication and compared the incidence of catheter-related complication between domestic-made and foreign-made ones. We also studied to elucidate whether the morphologic characteristics of the intravenous catheter will effect the incidence of catheter-related complication. METHOD: From July 1 to Sept 30, 1998, we surveyed the incidence rate of intravenous catheter-related complication among the hospitalized patients in the wards of Medicine. Surgery, Obstetric, and Neonatal Intensive Care Unit in Guro Hospital, Korea University Medical center. We also compared the incidence of complication between domestic-made catheter (catheter A) and foreign-made catheter (catheter B) of three different gages (24G, 22G and 18G). The morphologic characteristics of intravenous catheters has been studied by electron microscopy. RESULT: Complication associated with use of intravenous catheter had been occurred 263 out of 459 cases (57.3%), among those cases, non-infectious complication and infectious complication were 173 cases (37.7%) and 90 cases (19.6%), respectively. Totally, catheter A group showed higher complication than catheter B group [62.0% (160/258) vs 51.2% (103/201), P=.021]. Analysis on the incidence rate of complication according to the products did not show significant differences in the noninfectious complication in every gage groups. However the infectious complication occurred higher in the domestic-made catheter A group than among the foreign-made catheter B group [(24G: 6% vs 0%, P=.026), (22G: 25.6% vs 9.6%, P=.001), (18G: 36.8% vs 13.4%, P=.002)]. Duration of catheter life did not show the difference between catheter A group and catheter B group [48.5hrs vs 50.3hrs, P=.474]. The analysis on risk factors for complication showed that catheter A group is highly related (odd ratio 1.85). The morphologic analysis of the catheter by using electron microscopy showed that the angles in the tip of the introducing needle of catheter Aand catheter Bare 60degrees and 45degrees , respectively, and the bevel between introducing needle and catheter sheath are 50degrees and 27degrees, respectively. CONCLUSION: There was a higher incidence rate of complication related to domestic-made catheter usage, which might influence increasing the period of the hospitalization and the expenses due to the complication. The study of cost effectiveness analysis needs to be performed regarding intravenous catheter-related complication. Morphologically, catheter A showed more blunt angle in the tip and transition area of the introducing needle than the angle of catheter B, which is considered to influence the higher complication incidence. It needs to improve the quality of domestic-made intravenous catheter.

PURPOSE: The Purposes of this article are to illustrate the typical imaging features of eight patients with this syndrome and to discuss the advantage of each imaging modality with a concise review of literatures. MATERIALS AND METHODS: We retrospectively reviewed plain skull radiographs (6), computd tomographic(CT) scans(8), magnetic resonnance(MR) images(4) and cerebral angiograms(3) of eight patients with Sturge-Weber syndrome. We analyzed the radiographic findings of Stu rge-Weber syndrome and compared the findings of CT, MR and angiography. RESULTS: Plain radiographs showed characteristic gyriform calcifications(3) after 2 years of age. CT scans excellently demonstrated cortical calcifications(5), prominently enhancing choroid plexi(5) and dilated periventricular veins(2). MR revealed dilated deep cerebral veins as tubular or spot-like signal void structures at periventricular areas(3) and showed stripes of cortical enhancement after gadolinium infection(2). Angiograph showed dilated tortuous medullary and deep cerebral veins(3) as the collateral pathways of blood shunting. MR was superior to CT in the detection of parenchymal atrophy, venous abnormalities and the extent of angiomatous involvement. Angiography showed enlarged deep cerebral or medullary veins better than MR imaging. CONCLUSION: We think that each imaging modalit including CT, MR or angiography has unique advantages in the diagnosis of this syndrome but MR will be used frequently because of its superior ability for the detection of atrophy, vascular abnormalities and direct visualization of leptomeningeal angiomatosis with contrast enhancement.

PURPOSE: The aim of this study is to investigate the colonization rate of Methicillin-resistant Staphylococcus aureus (MRSA) in neonates by different clinical characteristics, to presume the origin of MRSA acquisition, and to identify the risk factors associated with MRSA colonization. METHODS: We retrospectively reviewed the medical records of 1,733 neonates admitted to Seoul Eulji hospital Neonatal Intensive Care Unit between January 2008 and December 2011. Nasal, inguinal and rectal swab specimens were obtained upon admission and each week until discharge. We classified the route of MRSA acquisition as; hospital associated (HA-MRSA) and community associated (CA-MRSA) according to the case definition. RESULTS: Among 1,733 neonates, 415 (23.9%) were colonized with MRSA. Gestational age, birth weight, delivery type, maternal antibiotics usage before delivery, birth place and care place before admission were influencing factors in colonization of MRSA. The colonization rate was significantly high in neonates without maternal prophylactic antibiotics use before delivery than in the other group (relative risk 2.77, 95% CI 1.88-4.07; P<0.01), and outborns showed higher MRSA colonization rate compared to inborns (relative risk 2.28, 95% CI 1.17-4.42; P=0.015). CONCLUSION: We identified the neonatal MRSA colonization rate to be 23.9%. We estimated HA-MRSA colonization rate to be 10% (51/511) and CA-MRSA colonization rate to be 36% (309/858). We ascertained that risk factors in MRSA colonization in neonates were prophylactic use of antibiotics in mothers and the birth place.
