PURPOSE: To investigate the visual prognosis, the interval, and the rate of development of after-cataract following cataract surgery in atopic dermatitis. METHODS: Twenty eyes of 13 patients diagnosed as cataract associated with atopic dermatitis were operated between January, 1994 and January, 2000. Visual acuity, postoperative inflammatory reaction, the interval, and the rate of development of after-cataract were investigated and compared with the cataract cases without atopic dermatitis. RESULTS: The average preoperative best corrected visual acuity of 20 eyes was 0.23+/-0.22. The average postoperative best corrected visual acuity at 1, 2, 7, and 12 months after surgery were 0.78+/-0.23, 0.83+/-0.16, 0.78+/-0.23, 0.83+/-0.26, respectively. These values showed no significant difference compared to the postoperative visual acuity of the cataract cases without atopic dermatitis. Aqueous flares measured with laser flare meter were 15.09+/-9.20, 11.15+/-4.68, and 7.38+/-0.75 photon counts/millisecond at 10 days, 1, and 2 months after surgery, which did not seem to influence the final visual acuity and the development of after-cataract (p>0.05). Among the 20 eyes, 66.67% finally developed after-cataract and the average time interval of the development of after-cataract was 11.25+/-4.22 months. CONCLUSIONS: Visual prognosis following cataract surgery in atopic dermatitis is good, while after-cataract seems to develop more frequently and earlier compared to the cases without atopic dermatitis.

BACKGROUND: Improvements in catheter equipments and increasing experience of the operators have brought about a broadening of the indications and applications of percutaneous transluminal coronary angioplasty(PTCA). In particular, coronary angioplasty has been employed in total occlusions.We evaluated the initial success rate and safety of PTCA total occulsive coronary artery disease. METHODS: To assess the success rate and safety of PTCA total coronary artery occlusion, the data of 24 patients(male 19, female 5, mean age 55+/-9 years), in whom PTCA for total occlusion were performed, were examined. RESULTS: Primary success rate of procedure was 66.7%(16 out of 24 lesions).The success rate according to the duration of total occlusions was 8 out of 11(72.7%) with occlusions<4 weeks duration and 3 out of 7(42.9%) with occlusions>4 weeks duration(p=0.07). There was no difference in success rate according to vassel dilate(left anterior descending 75.0%, right coronary 44.4%) and length of occluded lesion(0.93%+/-0.47%cm, p=0.35). Eight procedural failures included inability to cross the lesion with a guide wire in 6 and inability to dilate the lesion in 2, but there was no emergency coronary bypass surgery or cardiac death. CONCLUSION: Even though the recanalization of occluded coronary arteries has a lower initial success rate than angioplasty for stenotic arteries, PTCA in total occlusion can be performed as a safe and effective therapeutic modality in selective patients.

BACKGROUND: Indications and applications of percutaneous transluminal coronary angioplasty(PTCA) have been broaden recent years. We evaluated the initial success rate and safety of PTCA in mulitiple lesions and vessels. METHODS: To assess the success rate and safety of PTCA In mulitiple lesions and vessels, the data of 60 lesions from 28 patients(male 23, female 5, mean age 56+/-12 years), in whom PTCA for multiple lesions and vessels were performed, were examined. Initial results and complications were compared in 37 lesions undergoing multivessel and 23 lesions undergoing multilesion PTCA. RESULTS: Overall primary success rate of procedure was 82%(49 out of 60 lesions). Angioplasty was attempted in mean 2.1 stenotic lesions per patient. Primary success rate per lesion was 84%(31 of 37) among those who underwent multivessel and 78%(18 of 23) among those who underwent multilesion PTCA(p>0.05). Success rate according to the combination of dilated vessels was 85.7%(12 of 14) in left anterior descending(LAD) and left circumflex(LCX), 83.3%(10 of 12) in LAD and right coronary artery(RCA), 100.0%(4 of 4) in LAD and diagonal branch, RCA and LCX in 75.0%(3 of 4), and 66.7%(2 of 3) in LAD, LCX and diagonal branch. Eleven failures(18.3%) included inability to pass the guide wire cross the lesion or inability to locate the balloon catheter in 5(8,3%), abrupt closure in 2(3,3%), coronary spasm in 1(1.7%) and major branch occlusion in 3(5.0%), but there was no emergency coronary bypass surgery or cardiac death. CONCLUSION: Coronary angioplasty in selected patients with multivessel and multilesion coronary artery disease might be useful and have relatively good initial results, but the long-term efficacies with other forms of treatment must be evaluated prospectively.

"Dual LAD" was defined as the early bifurcation of the proximal LAD into two vessels : a short LAD which remained in the anterior interventricular sulcus and does not reach the apex, and a long LAD which leaves the anterior interventricular sulcus only to return to the distal sulcus and continue to the apex. Recognition of "Dual LAD" is essential to prevent errors of interpretation of the coronary arteriogram and for planning of optimal surgical therapy. We report 2 cases of "Dual LAD" with the review of the literatures.

Lipoprotein(a)[Lp(a)] is a LDL-like particle with a glycoprotein called apo(a) attached to its apoB through disulfide bond. Many case-control studies support the opinion that plasma Lp(a) levels were associated with coronary artery disease. This study was conducted to assess the relationship between plasma Lp(a) level and coronary artery disease in Korean population. Serum levels of Lp(a), in addition to other lipids and known clinical risk factors for coronary artery disease were determined in 92 subjects undergoing coronary angiography. Among them 30 patients had no obstruction in the coronary artery(cath-control group), while the others revealed the presence of coronary artery stenosis more than 50%(CAD group). The Lp(a) levels of the CAD group were significantly higher the those of cath-control group(31.8+/-25.0mg/dl vs 14.6+/-11.9mg/dl, p<0.005). Other lipids except triglycerides(166.9+/-70.5mg/dl vs 116.2+/-56.1mg/dl, p<0.005) were not significantly different between two groups. The patients with significant coronary artery disease of two or more vessels were found to have higher Lp(a) levels than those of one vessel disease. Lp(a) levels had no relations with other lipids, diabetes, smoking, hypertension and age. Stepwise discriminant analysis revealed that Lp(a) was the best discriminator among risk factors for coronary artery disease. These results suggested that Lp(a) level was a significant independent risk factor for coronary artery disease.

This study was done to determine the value of thallium-201 stress myocardial perfusion scanning for identifying disease in the individual coronary arteries. Segement analysis of rest and stress myocardial perfusion scanning was performed in 65 subjects who underwent coronary arteriography. Anterolateral wall detects had a sensitivity of 70%, a spectivity of 92%, and a predicitive accuracy of 93.3% for identifying left anterior descending(LAD) coronary artery disease(CAD). Anteroseptal wall defects had a sensitivy of 62.5%, a specificity of 80%, and a predictive accuracy of 83.3% for identifying LAD CAD. Septal wall defects had a sensitivity of 67.5%, a specificity of 92%, and a predictive accuracy of 94.4% for identifying LAD CAD. Inferior wall defects had a sensitivity of 65.4%, a specificity of 89.7%, and a predictive accuracy of 80.9% for identifying right CAD. Posterolateral wall defects had a identifying left circumflex CAD. Thus, although senmental analysis of stress myocardial perfusin scanning can identify LAD CAD with high sensitivity and specificity, only moderate sensitivity and specificity are achieved in identifying right CAD or left circumflex CAD. But stress myocardial perfusion scanning has tendency to identify the most severely ischemic area, use of segmental analysis may be of benefit in the evaluation of patients with ischemic heart disease before or after coronary artery bypass graft and percutaneous transluminal coronary angioplasty.
