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: In elective intervention, the implantation of an intracoronary stent is an established treatment modality to reduce restenosis in comparison with balloon angioplasty. However, stenting was empirically thought to be contraindicated for acute myocardial infarction because of the propensity for thrombosis, althought the percutaneous transluminal coronary balloon angioplasty(PTCA) on infarct-related artery is associated with a high incidence of restenosis. To knowlege, there is no report comparing the longterm efficacy of coronary stenting with PTCA in patients with acute myocardial infarction. Accordingly, we investigated the effect of stent implantation on restenosis of infarct-related artery in acute myocardial infarction, comparing with conventional balloon angioplasty. METHOD: From January 1994 to December 1995, 97 patients (stenting in 45 patients : PTCA in 52 patients) underwent intracoronary stenting or PTCA on infarct-related artery successfully at 7-10 days after onset of infarction. The coronary stents were Palmaz-Schatz stent in 35 patients and Cordis stent in 10 patients. Follow-up coronary angiography was performed in all patients 6 months later after intervention. RESULTS: No death, emergency coronary artery bypass surgery or reinfarction occurred during hospitalization in 97 patients. In 45 patients with stent implantation, no stent thrombosisoccurred. The 6-months angiographic restenosis rate was 13 percent in patients assigne to stent implantation and 52 percent in patients assigned to PTCA(p<0.05). CONCLUSION: We conclude that the intracoronary stent implantation on infarct-related artery at 7-10 days after acute myocardial infarction is safe, feasible and significantly reduces the restenosis rate.

PURPOSE: Ultrasound (US) and US-guided fine needle aspiration biopsies (FNAB) are considered the modalities of choice for assessing lymph nodes suspected of containing metastases, but the sensitivity of FNAB varies and is specific to the operator. We analyzed the risk of FNAB providing false negative results of lateral neck node metastasis, and evaluated diagnostic accuracy of FNAB, in patients with papillary thyroid cancer. MATERIALS AND METHODS: FNAB was performed in 242 patients suspected of having lateral neck node metastasis on preoperative imaging. Thyroglobulin in the fine-needle aspirate washout (FNA wash-out Tg) and computed tomography enhancement (Hounsfield units) were measured. Patients with negative results on FNAB were examined by intraoperative frozen section. The false negative and true negative groups were compared. RESULTS: Of the 242 patients, 130 were confirmed as having lateral neck node metastases. In 74 patients, the metastasis was identified by FNAB. False positive results were observed in 2 patients (0.8%) and false negatives in 58 (44.6%). Risk analysis showed that patient age <45 years (p=0.006), tumor size >1 cm (p=0.008) and elevated FNA wash-out Tg (p=0.004) were significantly associated with false negative results on FNAB. The accuracy of FNAB increased significantly when combined with FNA wash-out Tg (p=0.003). CONCLUSION: To reduce the false negative rate of FNAB, patient age (<45 years), tumor size (>1 cm) and FNA wash-out Tg (>34.8 ng/mL) should be considered in preoperative planning. Accuracy may be improved by combining the results of FNAB and FNA wash-out Tg.

A human malignant lymphoid cell line(JeKo-1) was established from a Korean patient with retroperitoneal tumor presenting peripheral blood and bone marrow involvement by malignant lymphoid cells. This cell line was established from peripheral blood, and the cell line had the identical immunophenotypic features as malignant cells from the peripheral blood. The established cell line had features of a mature B-cell phenotype with no evidence for commitment to other lineages. The JeKo-1 grows in suspension with a doubling time of 33 hours. By light and electron microscopic examination, the established cells had a follicular center showing, a small, cleaved, lymphoid appearance, and had a large amount of cytoplasm containing few vacuoles and an irregular cytoplasmic membrane. Immunophenotypic analyses with monoclonal antibodies using flow cytometry showed a monoclonal IgM kappa and CD5- B-cell phenotype. The cells were non-reactive for T-cells and myeloid/monocyte antigens, and no evidence of Epstein-Barr virus nuclear antigen by polymerase chain reaction. DNA analysis showed a hypodiploid stemline with a DNA index of 0.83. The established cells were strongly reactive for bcl-2 and c-myc onco-protein, but lacked expression of multidrug resistance gene protein, p-glycoprotein by Western blot analysis. Karyotypic analysis of JeKo-1 showed 40-41 chromosomes. This cell line should be a valuable tool to study the dissemination of malignant lymphoma into the peripheral blood and bone marrow.
