Authors experienced 100 cases of retrobulbar optic neuritis among the patients who visited the Chang Shoo Choi Eye Clinic during the last 2 years, from September 1, 1964 to August 31, 1966. The chief complaints are asthenopia, blurring vision, ocular pain, headache and photophobia. Of 100 cases, 46 cases wanted to be refracted. The corrected visual acuities are not always poor, though they are very variable from time to time as the tests are processing. The most cases revealed central relative scotomas instead of cecocentrals as previously believed. Fields are taken with glasses if corrected. In our cases, the age distribution of the patients are very interesting, the most susceptible age groups are 11~13 years.

It is evident that an elevation of airway albumin excreation rate without clinical proteinuria strongly predicts a later progression on diabetic renal disease. So we studied the correlation between Microalbumin checkly RIA & Micral-Test®. We collected urine between 08:00 h and 08:00 h next day and then checked microalbuminuria by radioimmunoassay method and Micral-Test® The results are as follows: 1. There was significant correlation between microalbuminuria checked by RIA & Micral-Test® 2. There was poor correlation between diabetes duration or HV-A1c and maximal change in albumin excreation rate. 3. So we concluded that Micral-Test® can be used in laboratory instead of RIA.

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.
