A Clinical study was done on 90 cases of acute myocardial infarction admitted to Busan Wallace Memorial Baptist Hospital from January, 1977 to Febuary, 1983. The following results have been obtained. 1) The ratio of male to female was 2.2:1. The most age group were 5th decades(35.6%) and over 5th decades(5th decades and 6th decades) were two-thirds of all age group. And annual incidency were increasing tendencies, in 1980-1982 than 1977-1979. 2) Between the preceding diseases and the risk factors, the most common cause was the smoking (60%). And other associated diseases and factors were hypertension(54.4%), hypercholesterolemia (43.8%), hyperlipidemia(51.4%) and angina pectoris (34.4%). 3) The most common inducing factor was physical exertion(33.3%). And others were emotional stress(23.3%), alcohol drinking(10%), rest and sleeping(5.6%). 4) The major symptoms of acute myocardial infarction were precordial or epigastric pain(96.7%), dyspnea(53.3%), radiating chest pain (51.7%) and painless infarction(3.3%). 5) On laboratory data, there were leukocytosis in 50.5% increased SGOT in 68.6%, increased serum LDH in 75.9% and cardiomegaly in chest x-ray film were 82 percents. 6) The ratio between the anterior and inferior infarction on EKG was 1.9:1. 7) When admission, normal sinus rhythms on EKG were 59 percents. And the common associated electrocardiographic abnormalities were ventricular premature beat (23.6%), atrial fibrillation(15.7%), first degree A-V block (15.7%), left ventricular hypertrophy(15.7%). The most common abnormality was ventricular premature beat(23.6%). 8) The mortality rate of acute myocardial infarction was 10 percents. The causes of death were heart failure(33.3%), ventricular arrhythmia(33.3%), sudden death (22.2%) and cardiogenic shock(11.1%).

BACKGROUND: There has been a change in the causes of aortic stenosis when comparence of rheumatioc aortic stenosis in recent year. Therefore, we studied the etiology factor of pure aortic stenosis. METHODS: The gross surgical pathologic features of the aortic valves were reviewed in 92 patients with pure aotic stenosis whom underwent aortic valve replacement at Yonsei University, Cardiovascular center between July 1989 and June 1994. RESULTS: The three most frequent causes were 1) calcification of congenital bicuspid valve in 30%, 2) degenerative calcification of aortic valve in 22%, 3) rheumatioc valvular change in 48%. The mean age at the time of aortic valve replacement for the entire series of patients was 54.4 years. The range of age was from 18 years to 77 years. Males predominated for degenerative disease and congenital bicuspid valves, but there were reversed rheumatic origin. One or more complications occured in 17% of patients undergoing operation. The surgical mortality was 3.3%. CONCLUSION: Our data suggest that more common cause of aortic stenosis is non-rheumatic disease rather than rheumatinc origin.

The metal ceramic crown is currently the most popular complete veneer restoration in dentistry, but in many cases, the metal cervical collar at the facial margin is unesthetic and unacceptable. Facial porcelain margin has been used in place of it. But this dose not solve the problems, such as dark gingival discoloration and cervical opaque reflection of porcelain veneer. Recently, metal copings which were designed to terminate its labio-cervical end on the axial walls coronal to the shoulder have been clinically used to solve the esthetic problem of metal ceramic crown. But in this design, porcelain veneer of labio-cervical area which is not supported by metal may not be able to resist the stress during cementation and mastication. The purpose of this study was to evaluate fracture strength and fractured appearance of crowns according to different coping designs. A resin maxillary left central incisor analogue was prepared for a metal ceramic crown, and metal dies were made with duplication mold. Metal copings were made and assigned to one of four groups based on facial framework designs: group 1, coping with 0.5mm metal collar; group 2, metal extended to the shoulder; group 3, metal extended to 1 mm coronal to the shoulder; group 4, metal extended to 2mm coronal to the shoulder. Copings and crowns were adjusted to be same size and thickness, and cemented to metal dies with zinc phosphate cement by finger pressure. Fracture strength was measured with Instron Universal Testing Machine. Metaldies were anchored in Three-way-vice at 3mm below finish line and at 130degree inclined to the lone axis of the crown. Load was directed lingually at 2mm below midincisal edge. Load value at initial crack and at catastrophic fracture was recorded. The results obtained were as follows: 1. Fracture strength values at initial crack were higher in groups 1, 2 than in groups 3, 4 but this difference was not statistically significant(P<0.05). 2. Conventional metal collared crown had greater catastrophic fracture strength than any other collarless crowns. 3. The greater the labial metal coping reduction, the lower the catastrophic fracture strength of crowns but when more than 1mm of labial metal reduction was done, the difference in strengths was not statistically significant(p<0.05). 4. The strongest collarless coping design was group 2.

Purpose: In the present study, an atypical case of multiple evanescent white dot syndrome (MEWDS) was reported, which thewhite dots of acute phase and the pigmented patches of recovery phase appeared on different location.Case summary: A seventeen years old male with no previous medical history was presented with decreased visual acuity of hisleft eye. On the first visit, his maximum corrected vision was 1.0 in right eye and 0.5 in left eye. The white dots with blurry marginwere noted at the nasal retina on fundus exam. Fundus autofluorescence photography, fluorescein angiography and indocyaninegreen angiography all showed typical foundings of MEWDS. Gradually the vision improved up to 1.0 with maximumcorrection in six weeks, with normalized ellipsoid zone contour. However, multiple panretinal pigmented patches appeared diffusely,not only at nasal, where the previous white spots were noted, but also at temporal. The patient was followed up withoutany medication. Finally, the pigmented lesions were disappeared spontaneously. Conclusions During the recovery phase of MEWDS, multiple pigmentations may appear in different part of the retina, where thewhite dots were not presented. However, they were disappeared with recovery of clinical symptoms gradually without anytreatment.

Purpose: To investigate the influence of cataract surgery on detection of a foveal avascular zone (FAZ) and retinal capillary density (RCD) by optical coherence tomography angiography (OCTA). Methods: In this study, 64 eyes of 64 patients with cataracts who underwent surgery were included and studied retrospectively. All patients underwent cataract surgery of the included eye and a FAZ was detected on OCTA preoperatively and postoperatively using one of two kinds of OCTA devices. The FAZ and RCD were compared before and after cataract surgery using paired t-test. Results: Using the Cirrus Angioplex OCTA device, there was no significant pre- or post-operative difference in the FAZ area (p = 0.060), perimeter (p = 0.052) and circularity (p = 0.190). It also revealed no significant difference between the central (p = 0.310), inner (p = 0.310), and outer (p = 0.310) zones and full RCD (p = 0.228) before and after cataract surgery The Spectralis OCTA device also showed no significant difference in the FAZ area (p = 0.239) before and after cataract surgery. Conclusions Cataract surgery does not affect detection of the FAZ and RCD on OCTA. Although patients who have a FAZ-related retinal disorder such as diabetic retinopathy and undergo cataract surgery are followed up regularly, it seems that the results gained by OCTA are reliable and comparable to the preoperative result.

PURPOSE: In the present study, two cases of intraoperative acute opacification of hydrophilic intraocular lens were reported. CASE SUMMARY: (Case 1) A sixty-seven year-old female presented with chronic visual impairment. Slit lamp examination revealed nuclear cataract of the left eye. Cataract surgery for her left eye was performed. A hydrophilic intraocular lens was checked before implantation and no defect was noted. Immediately after the implantation of the intraocular lens, acute whitish opacification of the intraocular lens occurred. However, the intraocular lens was not explanted, and the opacification cleared after one day. (Case 2) A 65 year-old male presented with chronic visual impairment of the left eye. Nuclear cataract of his left eye was noted, and he went through cataract surgery of the left eye. After the implantation of intraocular lens, acute whitish opacification of the intraocular lens was noted but it disappeared a day after. CONCLUSIONS: Intraoperative acute opacification of intraocular lens seems to occur due to radical temperature change. There is no need to remove or exchange the intraocular lens as opacification tends to clear within a day. No structural or mechanical change of intraocular lens was noted after opacification. Careful management of temperature for intraocular lens storage is necessary for prevention of intraoperative intraocular lens clouding.

PURPOSE: We report a case of unilateral, focal, pigmented paravenous retinochoroidal atrophy (PPRCA). CASE SUMMARY: A 46-year-old female visited our clinic in complaint of a vague problem with her right eye identified during a general medical examination. The visual acuity (without correction) of both eyes was 1.0. Slit-lamp examination of both eyes revealed no specific signs. Fundus examination of the right eye revealed focal, bony-spicule-shaped retinochoroidal atrophy with pigmentation along the course of the superior retinal vein. A fundus autofluorescence examination revealed principally hypofluorescence with some hyperfluorescence at the margin of the atrophic retinochoroidal lesion. Optical coherence tomography revealed mixed clumping and atrophy of the retinal pigment epithelium (RPE) layer and thinning of the choriocapillaris layer. Fluorescence angiography revealed a window defect and blockage at the site of the lesion (the fluorescent material did not enter the lesion). The site of the window defect was in correlation with the atrophic RPE region. The site of the blockage at lesion also matched with the site of the regional pigment clumping. No definite leakage was observed. CONCLUSIONS: To the best of our knowledge, this is the first case of unilateral focal PPRCA reported from Korea.
