PURPOSE: The purpose of this seroepidmiologic study was to examine the immunization and infection history of rubella, positivity of rubella specific antibody, seroconversion rate of two rubella vaccines and to develop an adequate immunization program of rubella. Research Methods : Subjects of the study were 2.071 students of 8 priamary schools in Gyenggi-Do. Questionnaire and blood sampling were done. Test method of Rubella specific antibody was ELISA (Abbott IMx autoanalyzer). The anayltic methods for the study were chi-square-test, t-test and ANOVA. RESULTS: The results of the study were as follows : (1)The number of subjects who had infection history of rubella were only 28 students(1.5%). (2)The immunization rate of rubella was the highest in 6 year-old group(65%), it decrease as subjects grow older. (3)The positivity of rubella antibody was 76. 6%, it is the highest in 6 year old group and the lowest in 7 year-old group and it increase again as subjects grow older. (4)Average antibody titer was 53.3 IU(SD 79.2), the trend of antibody titer by age was similar to that of positivity. (5)The seroconversion rates of both vaccines, vaccine A,vaccine B, were 99.5% and 99.6%, the ratio of increase of antibody titer after immunization was higer than 400. it means that both vaccines are very efficacious. CONCLUSION: Results of the study suggest that it is necessary to increase the coverage of rubella immunization, and further studies are necessary to get more information for rubella.

The author fractographically analyzed the cause of metal failure (the first time this procedure has been used for this metal failure) and also analyzed in clinically. In this study, I selected eight cases which have been analyzed fractographically. In all these cases, the analysis was done after treatment of metal failure of implants internally fixed to femur shaft fractures at the Department of Orthopedic Surgery, Yeung-Nam University Hospital during the six year period from May 1983 to September 1989. 1. Metal failure occurred in five dynamic-compression plates, one Jewett nail, one screw in Rowe plate, and one interlocking nail. 2. The clinical cause of metal failure was deficiency of medial buttes in five cases, incorrect position of implant in one case, and incorrect selection of implant in two cases. 3. The time interval between internal fixation and metal failure was four months in one case, between five months to twelve months in six cases, three years in one case. 4. The fractographically analytical cause of metal failure was ; first, impact failure, one case, second, fatigue failure, six cases, machining mark (stress riser), four case type: low consistent cyclic fatigue failure irregular cyclic fatigue failure third, stress corrosion crack, one case. 5. 316 L Stainless Steel has good resistance to corrosion. However, when its peculiar surface film is destroyed by fretting, it shows pitting corrosion. This is, perhaps, the main cause of metal failure. 6. It is possible that mechanical injury occurred in implants during the manufacturing of implants or that making a screw hole in the main cause of metal failure.

Mucormycosis is an opportunistic fungal infection caused by the mucorales, which consist of the Rhizophus, Absidia, Mortierella, and Mucor. The diverse clinical forms of mucormycosis can be categorized as rhinocerebral, pulmonary, disseminated, gastrointestinal, cutaneous and miscellaneous. Although it can cause disease in healthy people, it most commonly affects patients who are diabetic or immunosup-pressed. Rarely, mucormycosis develops confined to the subcutaneous tissue. We experienced a case of cutaneous mucormycosis developed in a well-controlled diabetic patient who had previously injected foreign material on her face for an aesthetic purpose at the behest of an unlicensed physician. The patient had tissue necrosis and purulent discharge on her left cheek. Following histologic examination, we diagnosed the condition as cutaneous mucormycosis and treated it by wide excision combined with amphotericin B therapy. The disease was cured without any significant sequelae within 6 months of follow up. Cutaneous mucormycosis is rarely reported but it can cause facial deformity due to tissue necrosis, so that early diagnosis and appropriate treatment are important. Currently, foreign material injection for aesthetic purposes is still performed by unlicensed physicians. We present a case report concluding that one should consider the possibility of fungal infection in skin lesion in diabetic or other immunosup-pressed patients. We also emphasize the seriousness of illegal injection of foreign material.

In analyzing the postoperative results or evaluating the velopharyngeal incompetence after palatoplasty, speech evaluation is the inevitable factor. However, a standardized method for evaluating the speech problem in Korean cleft palate patients has not been available until now. So, the authors tried to establish a method of speech evaluation which is simple, economic and applicable to young patients, and to make a scoring method of the speech results in cleft palate patients based on the 'hypernasality diagnosing tool for cleft palate patient (OK Ran Jung)' which is commonly used by domestic speech therapists. The authors adopted the 'hypernasality diagnosing tool for cleft palate patients (OK Ran Jung)' male and female of children and adults, each consisting of 10 patients and make them speak according to the items about hypernasality and misarticulation evaluation, and record the results. We also calcuted the degree of the formants of the vowels (/a/, /o/, /u/)using sound spectrography. We examined the interjudge and intrajudge reliance of speech evaluation among the 10 inverstigators, revised the evaluation tool, devised the scoring method according to the above results, and compared the scoring results with those of sound spectrography to prove the reliance of our speech evaluation tool. With the scoring method, the authors could estimate the degree of hypemasality and misarticulation in cleft palate patients with evidence of reliability based on point-to-point agreement in two items. In comparing the results of our scoring method with the formant of vowels using sound spectrography, staistical significance existed except /u/F2 and that meant that our scoring method was reliable. We suggest that this simple, economic and reliable method of speech evaluation in cleft palate patients can create the basis for speech evaluation in patients of cleft palate and velopharyngeal incompetence under circumstances in which the results of various speech treatments are evaluated in comparison to various methods of speech evaluation.

Many methods of correcting secondary cleft lip nose deformity have been introduced, but a single best method that can be uniformly adjusted for all cases does not exist. Since it is difficult to make the nostril of the cleft side symmetric with that of normal side, the authors tried to formulate the basis for correction of unilateral secondary cleft lip nose deformity according to the varying amounts of deformed nostril. We then adopted 4 different methods of correcting the soft tissue and nostril deformity in 63 patients from 1996 to 1998 and surveyed the results. Our principles were as follows: 1) Alar rim incision was done in cases of different-shaped cleft-side nostrils with nearly the same measured area in comparison to the normal side. 2) When deformity of the alar-columellar web was severe, we performed modified Z-plasty. 3) When the nostril of the cleft-side nostril was smaller than the normal side with slight asymmetry, reverse W-plasty was done. 4) We adopted a reverse-U incision when there was a discrepancy in height with moderate asymmetry compared with the normal nostril. After dissection, repositioning of alar cartilage was done by same method in each case. A nasal stent was kept in position for at least 6 months postoperatively in almost all cases. After follow-up of 6 to 24 months, we concluded that our choice was correct in selecting the optimal operative method, considering the characteristics of deformity of the cleft side nostril in an effort to make it symmetric with that of the normal side.

Augmentation mammoplasty can be done in various manners according to the way of approach. the type of implant or implatation site depending on the status and demand of the patients or the operator's preferrence. In reviewing the many published reports about augmentation mammoplasty, they compare their surgical outcomes with mixed factors, so it is difficult to compare the results of mammoplasty simply with one factor under the same conditions. We think that analyzing the surgical results with one consistent method enables to compare and decide the influencing effect of one factor within it in augmentation mammoplasty. We could find the fact that the Korean women who wanted augmentation mammoplasty had same physical characteristics and demands, so developed the standardized method of augmentation mammoplasty among those debatable data for the purpose of increasing the patients' satisfaction, decreasing the complications, and shortening the operation time. The method we adopted was placing the implant through transaxillary subpectoral approach and using the endoscope auxiliarily in additional dissection and hemostasis. We employed saline-filled implants of round, textured type with the size ranging fro 125cc to 175cc and overinflated them by 10 to 30% beyond its original volume. After irrigation of the dissected pocket, we placed the suction drainage system into the subpectoral pocket. We educated the patients to massage their breasts right after removal of the drain. During the period of follow-up (from 6 months to 24 months), most of the patients were satisfied with their operative results. Though we experienced one case of capsular contracture, one case of malposition of the implant, and three cases of scar contracture on axillar incision site, as a whole, we could minimize the complications associated with augmentation mammoplasty. We present our postoperative results with the conclusion that our standardized method of augmentation mammoplasty can bring results of high satisfaction rate, minimal complication, predictability of postoperative results, shortening of operation time when applied consistently to the Korean patients whose physical characteristics are similar. We also hope that stanadardized method can be used to compare the influencing effect of many factors in the case of changing one factor within the standardized in the future follow up period.

PURPOSE: Due to its size and locatin, the liver is frequently injured in abdominal trauma. Recently, nonoperative management for liver injuries has been extended due to the development CT imaging, intensive care units, and their equipment and techniques. Herein, patients with traumatic liver injury were analyzed to evaluate its treatment and prognostic factors. METHODS: From 2001, January to 2003, July, 65 patients at our facility were confirmed to have traumatic liver injury. The operative or nonoperative managements were decided on the basis of the systolic blood pressure if no peritoneal irritation sign was noted. If the systolic blood pressure was stable, or recovered to within the normal range following hydration and transfusion at the emergency room, patients were managed nonoperatively. Hemodynamically unstable patients were managed operatively. The data were analysed using the SPSS program (Chi-squared tests and logistic regression analyses). RESULTS: 48 patients were treated nonoperatively, with 3 mortalities. The overall mortality rate was 15.8%, but only 6.4% in the nonoperative management group, compared to 67% in operative management group. In a Multivariate analysis the systolic blood pressure was found to be a reliable factor in traumatic liver injury and the mentality and ISS (injury severity score) reliable in finding complications in the nonoperative management group. The mentality was found statistically reliable for determining mortality in the operative management group, with the exception for the systolic blood pressure. CONCLUSION: The systolic blood pressure was an important indicator when considering the treatment plan in traumatic liver injury. An extensive study will be required that incorporates both nonoperative and operative management groups.
