Korean Circulation Journal 1973;3(2):1-18
The electrocardiograms of a total of 12,796 patients taken in the past three years at Severance Hospital were reviewed for conduction disturbances which were found in 314 cases(2.46%). Th first degree atrioventricular block occurred in 65 cases, and second degree atrioventricular block with Wenckebach periodicity in 13. There were 9 cases of third degree atrioventricular block with nomal QRS complexes causing Adams-Stokes attacks which represented 2.9% of all conduction disturbances. It occurred equally in both sexes and predominantly after 6th decade of life. There were 99 cases of complete right bundle branch block(RBBB) and 12 cases of complete left bundle branch block(LBBB). The latter were mainly associated with significant heart diseases. As for the intraventricular conduction defects other than the simple bundle branch blocks, the findings were as follows; 1. Simple hemiblocks were found in 92 cases or 0.73% of total series and 29.3% of all conduction disturbances. Left anterior hemiblock(LAH) occurred 3 times more frequently than left posterior hemiblock(LPH). 2. Partial bilateral bundle branch block(BBBB) were found in 25 cases representing 0.2% of the total series and 8.0% of all conduction disturbances. Among the 25 cases of BBB, 11 had RBBB plus LAH, 10 RBBB plus LPH, 1 LBBB plus first degree A-V block, and 3 LBBB of diphtheritic cardic involvement. Trifascicular heart block causing Adams-Stokes attacks occurred in 9 of the 25 cases resulting in death in 7 cases. The underlying diseases were ischemic heart disease, hypertensive heart disease, congenital heart disease and diphtheritic carditis. This report represents the first electrocardiographical documentation of occurrence of trifascicular heart block progressing from BBBB in Korea.

Korean Circulation Journal 1972;2(2):53-55
A 45 year old man with a history of syncopal attacks of 3 days' duration showed complete heart block with occasional retrograde P waves following QRS complexes in the electrocardiogram. The site of A-V block seemed to be below A-V node judging from the QRS complexes when occasional capture occured. This may be a case of complete heart block progressing from right bundle branch block plus left posterior hemiblock. There was a rapid improvement of conduction with sublingual isoproterenol in a few days, EKG's showing normal A-V conduction and QRS complexes on discharge. The mechanism of the retrograde conduction in the presence of complete heart block is discussed with a review of literature.

Many modalities of the treatment of fractures of distal 1/3 of tibia were introduced. But, May anatomical bone plate is considered to be a valuable method in treating distal 1/3 tibial fractures because of reduction potentiality by their contour, ability of firm fixation, decreased complications. Twenty two patients having distal 1/3 tibial fractures, were treated by May anatomical bone plate, at the Department of Orthopedic Surgery, Inchon Chirstian Hospital from January 1988 to December 1993. The results were follows; 1. Ninteen cases(86%) out of 22 were closed fractures and the remaining 3 cases(14%) were open fracrues, the comminuted fractures were 6 cases(22%) and the segmental fractures were 2 cases(9%). 2. Average interval from injuy to operation was 16.8 days and 21 cases had associated injuries. 3. The mean duration of bone union was 16.9 weeks. 4. Seven cases(31.8%) of delayed union and two cases(9.1%) of superficial infection were noted.

5.Clinical Observations on Cosmetic Ocular Tatooing.
Journal of the Korean Ophthalmological Society 1989;30(2):289-297
To investigate the present status with its side effect of ocular tatooing for cosmetic purpose in our country, 150 patients with the eyelid and eyebrow tatooing who visited my clinic from July 1986 to October 1988 were enrolled in this study. Six patients who complained the early complications after the cosmetic tatooing were included in the tatooing group, and 150 patients without the tatooing were used as a control group for the statistical study. The following results were obtained: 1. The ages tatooed ranged from 19 to 68 years old age with the mean age of 39.65 +/- 9.46 years. Fourth and fifth decades consited of 76% of the total subjects tatooed. 2. At their first visit, blepharitis, external hordeolum, pingueculitis, subconjunctival hemorrhage and keratitis were more statistically frequent than the control gruop(p<0.05), but chalazion was not so. 3. Cosmetic tatooing was gradually noted after 1984 and was most frequently performed in 1986(41%). Thereafter, it reduced from 1987(35%) until now. 4. One half was tatooed once and 1 to 3 times of tatooing were added for the remainder. 5. Ninetyseven % of tatooing was done by non-medical doctor in beauty parlor or the other places excluding the hospital, and only 3% was performed by medical doctor in the hospital. 6. Eyelid tatiooing was noted in 96% of the total subjects tatooed and eyebrow tatooing was shown in over half of them(53%). 7. Early complication of the tatooing was confirmed by history taking in 29% of the total subjects tatooed, which consited of lid swelling(23%), subcutaneous hemorrhage of lid(4%), itching sensation(2%) and conjunctival redness(1%). Clinical Observations on Cosmetic Ocular Tatooing Six patients were treated for one to 10 days for the early complication of tatooing under the diagnosis of lid edema(100%), keratitis(83%), subcutaneous hemorrhage of lid(50%), blepharititis(33%), conjunctivitis(33%), corneal abrasion(33%) and conjunctival foreign body(17%). 8. Thirtysix % out of the patients confirmed by history taking was regretful after the cosmetic tatooing.

6.Factors Related to Clinical Vasospasm after Aneurysmal Subarachnoid Hemorrhage.
Journal of Korean Neurosurgical Society 1996;25(11):2192-2200
Authors analysed a series of 175 patients with aneurysmal subarachnoid hemorrhage(SAH) who have undergone the treatment for subarachnoid hemorrhage from July, 1990 to May, 1994 to assess the clinical factors related to clinical vasospasm. This investigation revealed following conclusions. 1) The severity of subarachnoid hemorrhage as seen on computed tomography seemed to be correlated with the appearance of clinical vasospasm. Patients with severe SAH on initial CT scan were at higher risk or clinical vasospasm. 2) Patients with history of hypertension had more significant clinical vasospasm than did normotensive patients after aneurysmal SAH. 3) Aneurysms of the anterior communicating artery were showen to have the highest incidence of clinical vasospasm. 4) Patients with moderate to severe diffuse vasospasm on cerebral angiography had more significant clinical vasospasm than patients with no or local vasospasm. These conclusions suggest that clinical vasospasm after aneurysmal SAH are related to the followi ng predictable factors;amount of blood on the initial CT scan;angiographic vasspasm;history of hypertension and location of aneurysm. Proper management of these factors may diminish the incidence and severity of clinical vasospasm and reduce the morbidity and mortality rate.

PURPOSE: We aimed to identify a more esthetic width-to-length ratio by analyzing maxillary central incisor of Korean adult population. Information regarding tooth ratio in the Korean population may be useful to clinicians when restoring anterior teeth. MATERIALS AND METHODS: A total of 40 men and 40 women were included in this study. The NON-MEDIA group included 40 non-celebrities, who were healthy and 25 to 39 years old, with normal dentofacial appearance. The MEDIA group consisted of 40 celebrities selected only on the basis of their soft-tissue facial appearance. The facial photographs of 40 celebrities were collected from the Internet websites. The width and length of the maxillary central incisor were measured using Adobe Photoshop(R) 7.0, a software for analysis, measurement and edition of photographs. Data were analyzed statistically using the Independent t-test at 5% statistical significance level. RESULTS: The mean ratio for the MEDIA group was 0.77, whereas that of the NON-MEDIA group was 0.88. The difference between the two groups was statistically significant. No significant gender differences were found in the width-to-length ratio in MEDIA group. In NON-MEDIA group, however, there were significant differences between female and male. CONCLUSION: After analyzing maxillary anterior teeth of Korean adults, our results were in accordance with the general Western standards of esthetics. A dentist restoring the natural look and beauty of teeth will have to consider those standards.

10.Stress analysis of anterior cantilever bridge.
The Journal of Korean Academy of Prosthodontics 2000;38(3):283-290
STATE MENT of PROBLEMS: Although some clinicians report long-term success with fixed partial denture (FPD) that contain cantilever pontic, the use of cantilever FPDs may be hazardous because of unfavorable leverages during mastication. PURPOSE of STUDY: This study aims to compare the stress induced in the periodontium with normal and reduced bone support, and to analyze the stress distribution patterns of anterior cantilevered FPDs using the finite element method. RESULTS: Cantilever bridge with a reduced bone level generated the highest peak stresses in the periodontium. In the models of reduced bone support, a cantilever bridge exhibited the greatest mobility and a 3-unit fixed restorations induced the smallest mobility of canine. The highest peak stress level of a 3-unit bridge in the periodontium is similar to the unrestored situation. But stress distribution in the bone is modified. CONCLUSION: In reduced bone support, a cantilever bridge exhibited the greatest mobility and stress.
