Recently, the number of cataract surgeries has rapidly increased. This study was devised to evaluate the post-operative daily life behavior and degree of satisfaction in the patients who underwent cataract surgery two or more years ago. Of 400 patients who underwent ECCE with IOL implantation, 125 patients[31%]replied to the mail questionnaire consisted of thirty questions. Hospital records were also reviewed. 84%of the patients were satisfied with outcomes of cataract surgery, which was significantly correlated with current visual acuity[p<0.01]. Degree of satisfaction was significantly higher in patients with bilateral surgery compared with those with unilateral surgery[p<0.05]. Age, sex, occupation, economic and general health status were not significantly associated with degree of satisfaction. As for life behavior, discomfort while driving an automobile was the most common complaint, especially in the patients who underwent unilateral surgery. Concerning ocular symptoms, many patients complained of foreign body sense, epiphora, glare, fatigue, and near vision discomfort. We reconfirmed that the decision to perform cataract surgery should be made with careful consideration of long term prognosis and above results.

Only a few cases of cyst related to cruciate ligament were reported in the literatrure. It is not only because of rarity but also difficulty of diagnosis by conventional method. Recentely, the precise intraarticular structure of the knee joint became to be seen by introduction of MRI and arthroscope and cycts would bave been found incidentally during the workup of the internal derangement of knee. We have experienced three cases of ganglion around the cruciate ligament in the patients whose symptom was mimic of intemal derangement of knee. We excised the ganglion with good clinical results.

Paraffinoma is a well known complication of previous paraffin injection into the subcutaneous layer that presents as various conditions including firm mass formation, edema, induration, ulceration, and skin necrosis. Paraffinoma can mimic neoplasm on physical examination and imaging studies and may complicate ultrasonographic diagnoses due to typical posterior shadowing and high echogenicity. When paraffinomas involve around the thyroid gland, the diagnosis of thyroid tumors is very difficult. We present a case of thyroid cancer, the evaluation of which was complicated by the presence of cervical paraffinoma.

BACKGROUND AND OBJECTIVES: The transradial approach for coronary intervention has a lower incidence of access site complications and can increase patient comfort after percutaneus tansluminal coronary angioplasty(PTCA). The purpose of this study is to compare procedural success and complication rates of percutaneous transradial coronary stenting which was performed by four operators in two hospitals with those using transfemoral approach. MATERIALS AND METHOD: From September 1998 to July 1999, one hundred seventy five consecutive patients(201 lesions) treated with coronary stent implantation were enrolled for this study : 84 patients underwent transradial coronary stenting(Radial Group), and 91 patients transfemoral coronary stenting(Femoral Group). RESULTS: Seven patients who failed coronary cannulation via radial artery were crossed over to the Femoral Group. The measurements of the radial artery were not done. Patient demographics were similar in both groups. Procedural success was similar in both group(95.2% in Radial Group vs. 97.8% in Femoral Group, p=S). All transradial coronary stenting were possible using conventional guiding catheters which are used in transfemoral intervention. Local vascular complication rates showed a trend toward a reduction in the Radial Group(2.4% vs. 8.8%, p=.06). CONCLUSION: This study showed the similarity in the safety and efficacy of transradial coronary stenting compared to those of transfemoral approach.

PURPOSE: Amniotic membrane (AM) contains various proteinase inhibitors and when used as a graft, it could enhance healing process by blocking insult of inflammatory cells and inhibiting proteolytic damage. Thus we evaluated whether applying of amniotic membrane extract as eyedrops could get the same effect as amniotic membrane patching. METHODS: Alkali wounds were inflicted on the central corneas of rabbits by applying a round filter paper, 6.0 mm in diameter, soaked in 1N NaOH for 30 seconds. A total of 16 rabbits were divided into four groups: (1) applied with amniotic membrane extract; (2) applied with amniotic membrane extract and Healon(R); (3) applied with methylcellulose; and (4) control. Each material was applied for 1 week. During follow-ups, epithelial defects, corneal thickness and its opacity were measured. RESULTS: The epithelial healing was faster and the corneal thickness was thinner in amniotic membrane extract applied groups than in non-applied. Corneal opacity was much less in AM extract applied groups. CONCLUSIONS: AM extract as eyedrops promotes wound healing and it could be an effective method for treating various keratitis due to its convenience and good effect.

Various bone grafting techniques have been reported for scaphoid nonunions. We describe surgical technique of osteosynthesis with bone graft using arthroscopic technique and percutaneous fixation as a minimal invasive procedure. Nine patients with scaphoid nonunion were treated with this technique, resulting in successful union at a mean of 10 weeks.

BACKGROUND: The clinical use of intracoronary stents is impeded by the risk of subacute stent thrombosis and complications associated with the anticoagulant regimen. The use of high pressure balloon dilatations and confirmation of adequate stent expansion by intravascular ultrasound provide assurance that anticoagulation therapy can be safely omitted. Therefore, we evaluated the effect of anticoagulation of subacute thrombosis sfter stenting retrospectively on a consecutive series of patients who received palmaz-Schatz coronary stents with high pressure balloon dilatation. METHOD: From March 1995 to August 1995, 62 patients underwent Palmaz-Schatz coronary stent implantation. After deploying stents successfully, high pressure overdilatation of the stents was performed in all patients. According to post-stent anticoagulation, 32 patients received aspirin 200 mg/day, ticlopidine 500 mg/day and warfarin for two months, 30 patients received aspirin and ticlopidine. RESULTS: The clinical or angiographic variables were not significantly different between the two groups. There was no acute or subacute thrombosis in the two groups. The hospital stay after stenting was significantly shorter in the patients without antcoagulation than in patients with anticoagulation. CONCLUSION: The Palmaz-Schatz stent can be safely implanted without anticoagulation provided that stent expansion is daequate by the use high pressure balloon dilatation This technique significantly reduces hospital time and vascular complications and has a low stent thrombosis rate.

BACKGROUND: Restenosis remains as the major limitation of percutaneous translumainal coronary balloon angioplasty (PTCA). Although its mechanism remains incompletely understood, proliferative action of arterial smooth muscle cells has been found to play an important role on restenosis by neointimal formation after PTCA. Glycosaminoglycan-containing compounds, including Sulodexide (Vessel Due , ALFA, Wasserman, S.p.A, Italy), inhibit the proliferation and maigration of vascular smooth muscle cells in vitro. OBJECTIVES: This study was performed to assess the efficacy of Sulodexide, a glycosaminoglycan compound with antithrombotic and antiproliferative properties, in preventing restenosis after PTCA. METHOD: Two hundred eighty-four patients with ischemic heart disease were randomized to receive either the standard PTCA without Sulodexide in 144 patients (control group, M : F = 99 : 45, Age = 58 +9 or -9), 160 lesions or the standard PTCA with Sulodexide in 140 patients (treated group, M : F = 89 : 51, age = 58 +10 or -10), 158 lesions. Successful angioplasties were performed in 258 atheromatous coronary lesions in 224 patients for whom follow-up angiographic data were obtained 6 month later. Quantitative coronary angiographic analysis (QCA) was performed before , immediate after PTCA and 6-month later. Angiographic restenosis (>50% diameter stenosis at follow-up) was the primary end point : miniamal luminal diameter at follow-up angiogram was the secondary end point. RESULT: Successful PTCA was 97.6% and 97.5% in the standard PTCA with Sulodexide and the standard PTCA without Sulodexide, respectively. Although reference vessel size and minimal luminal diamater after PTCA were larger in the control group than in the Sulodexide group(2.94+0.11 or-0.11 vs 2.83+0.13 or -0.13 mm and 2.26+0.12 or -0.12 vs 2.18+0.08 or -0.08 mm, respectively, p=NS), there was a increased tendency of minimal lumen diameter at 6 months angiogram in the Sulidexide group than in the control group (1.12+0.50 or -0.50 vs 1.07 + 0.53 or -0.53 mm, respectively, p=NS). Angiographic restenosis occured in 42% of lesions in the Sulodexide group and 52% of the control group (p=NS). CONCLUSIONS: Sulodexide treatment had a tendency to reduce restenosis rate in 6 months after coronary angioplasty. However, further study is necessary to verify the antiproliferative effect of Sulodexide with much larger number of patients.

OBJECTIVE: The introduction and development of the embolic protecting device (EPD) has resulted in a decreased rate of stroke after carotid artery stenting (CAS). The authors performed a retrospective study to investigate the risk factors for developing large emboli after CAS which can lead to ischemic events. METHODS: A total of 35 consecutive patients who underwent CAS between January 2009 and March 2012 were included in this study. Patients were divided into two groups including those with small emboli (group A; grade 1, 2) and those with large emboli (group B; grade 3, 4). The size and number of emboli were assigned one of four grades (1=no clots, 2=1 or 2 small clots, 3=more than 3 small clots, 4=large clots) by microscopic observation of the EPD after CAS. We compared demographic characteristics, medical history, and angiographic findings of each group. RESULTS: Thirty-five patients underwent CAS, and technical success was achieved in all cases. Twenty-three patients were included in group A and 12 patients in group B. Our results demonstrated that advanced age [odds ratio (OR) 1.24; 95% confidence interval (CI) 1.01-1.52; p=0.044] and smoking (OR 42.06; CI 2.828-625.65, p=0.006) were independent risk factors for developing large emboli after CAS. CONCLUSION: In patients with carotid artery stenosis treated with CAS, advanced age and smoking increased the number and size of emboli. Although use of an EPD is controversial, it may be useful in CAS in patients with risk factors for large emboli in order to reduce the risk of ischemic events.

An application of the multi-detector computed tomography (MDCT) for cardiac imaging is the non-invasive CT angiographic assessment of the cardiac morphology and the coronary arteries. The most important application is for the non-invasive diagnosis of coronary artery disease, and this includes assessment of coronary artery anomaly and stenosis, the evaluation of non-calcified atherosclerotic plaque and the follow-up examinations after stent deployment and bypass surgery. In the study, we have illustrated a variety of diseases of the coronay artery by using MDCT. These may facilitate the understanding of MDCT features of coronary artery lesions.
