Between August 1994 and June 1995, seventeen patients diagnosed as having partial or complete ruptures of the anterior cruciate ligament on MRI were managed by non-operative methods. Among them four patients were excluded due to operation during follow-up and the results were evaluated at a one year follow-up. We selected the patients prospectively for non-operative care using the selection criteria of age, degree of instability, activity level and patient compliance. The average age of them was 37.7 years. Initially knee stress test and MRI were checked, and Cybex study and Lysholm knee scoring were done at post-trauma one year follow-up. They were managed conservatively by ROM and muscle strengthening exercises and a brace fitting schedule for three months. Among them, six cases had partial tears and seven had a complete tear initially. At the one year follow-up, five of six cases who had shown partial ruptures, and two of seven cases with complete tears, recovered continuity of the ruptured ACL on MRI. Their Lysholm knee score was 84.4, and the Cybex test showed no difference in muscle power between the injured and uninjuried side. Those patients who had loss of continuity on follow-up MRI showed Lysholm score of 57.4 and decreased muscle power on Cybex study. Although there are still controversies about the adequate management of ACL injuries, our study suggests that conservative management is a viable alternative to surgery as long as the patients are selected prudently. For more concrete results, however, careful analysis based on a longer follow up period is necessary.

An epidemiological study on brugian filariasis was carried out in endemic areas including Cheju Island in Korea, with a brief review of literatures.The results showed that the incidence among residents has remarkably decreased in Cheju Island, which was the main endemic area. Reviewing available informations on the prevalence of filariasis reported in recent years and also judging from the present socio-economic conditions which enable people to practice personal protection against mosquitos, it can be said with confidence that filariasis has almost disappeared from Cheju Island and inland areas. The disease is considered to remain at a low level of endemicity in Hugsan Islands. Certainly mass diethylcarbamazine (DEC) treatment carried out in Cheju Island in the 1960s and 1970s and remarkable economic growth followed by improved living standard and altered life-style of inhabitants could all have combined effects on the disappearance of this mosquito-borne diseae in this island. If the present trends go on, the possibility of resurgence of filariasis in Cheju Island is hardly postulated.

A retrospective analysis of 29 patients with glottic cancer, treated at the Department of Therapeutic Radiology, Seoul National University Hospital. 97% of the patients was male. Of the 29 patients, stage T1N0M0 comprised 31%, T2N0M0 52%, and stage T3N0M0 14%. Local control rate with radical readiotherapy was 78% for stage T1N0M0, 60% for stage T2N0M0, and 50% for stage T3N0M0. 57% of the patients with the radiation failure was salvaged by surgery. The overall 3 year survival rate was 89% for the T1N0M0, 80% for stage T2N0M0, and 50% for stage T1N0M0, Among the survivors : 88% of T1N0M0, 75% of T2N0M0, and 50% T3N0M0 had an intact larynx and natural voice. It is concluded that radiotherapy is a highly effective method as the primary treatment of the early glottic cancer, emphasized on preserving of the larynx and natural voice.

A case of right-sided infective endocarditis in a 22-year-old male with ventricular septal defect of perimembranous type, right ventricular(RV) infundibular and pulmonic valve stenosis was reported. The vegetations were found on the mural endocardium of RV infundibulum and pulmonic valve. Streptococcus viridans was identified in 5 consecutive blood cultures, Pulmonary embolism and septic infarction in the lung was associated with systemic embolization, which was manifested by left renal infarction. The RV infundibular stenosis was due to anomalous muscle bundle at the proximal portion. Therefore, we thought that the mechanism of RV infundibular vegetation was probably due to 'Venturi effect and turbulence'. Several clinical features which were found in this case were also reviewed.

STUDY DESIGN: A retrospective analysis of 166 patients was undertaken to observe radiologically the changes of adjacent segments at follow-up more than three years after lumbar fusion. OBJECTIVES: The purpose of this study is to analyse the changes of adjacent segments and to correlate these changes to the length of using level and to the degree of deviation from physiologic lumbar lordosis. The authors also correlate these radiologic changes to the clinical symptoms. MATERIALS AND METHODS: In simple x-ray, authors observed traction spur, disc space narrowing, endplate sclerosis and vacuum phenomenon of adjacent segments. Authors used Gelb's criteria in segmental lordosis angle(SLA) and Katz's classification in clinical results. RESULTS: The average age was 49.6 years old and the average follow-up period was 57.2 months(4 years and 9.2 months). We observed radiologically the traction spurs in 35 cases(21.1%), end-plate sclerosis in 32 cases(19.3%), disc space narrowing in 33 cases(19.9%) and the vacuum phenomenon in 10 cases(6.0%). The numbers of fusion segments and the degree of unphysiologic segmental lordosis angle in fusion segments were related with the frequency and degree of changes of adjacent segments(P<0.05). The clinical results showed satisfaction in 142 cases(85.5%), unsatisfaction in 24 cases(14.5%) and low back pain in 24 cases(14.5%), leg pain in 11 cases(6.6%) and extension of fusion level in 4 cases(2.4%). In low back pain patients more than two kinds of radiological changes were frequently observed than the patients without low back pain(P<0.05). CONCLUSIONS: The radiological changes of adjacent segments were more frequently observed in long fusion and in fusion with unphysiologic lumbar lordosis angle. And these changes are frequently associated with low back pain. Thus long fusion and fusion with unphysiologic lumbar lordosis angle should be avoided if possible.

BACKGROUND: It is a popular notion that cutaneous ageing includes two distinct phenomenon; true ageing, a universal presumably inevitable change attributable to the passage of time alone, and photoageing, changes attributable to chronic habitual sun exposure that are neither universal nor inevitable. Numerous investigations with experimental animals, in vitro skin models have been conducted, although, few histological studies to date have attempted to announce fundamental morphological changes with innate ageing. OBJECTIVE: We compared skin derived from the breast of old and young persons using light microscopy to discern structural changes in epidermal and dermal morphology with advancing age. METHODS: The histological, immunohistochemical studies were performed with normal skin sections of thirty donors who were diagnosed with breast cancer. They were classified into three age cohort groups; nine into group I (22 to 38), twelve into group II(40 to 52), and nine into group III(54 to 87). We chose the breast as an area that might closely resemble intrinsically aged skin. This region is relatively shielded from photoageing by its anatomical location. Analysis of data was performed using the Kruskal-Wallis and ANOVA test for dermal parameters based on a 5-point rating scale, and a simple regression test for a positive rate of immunoreactants. Results : 1. Light microscopic appearance of aged skin revealed a more flattened epidermis than young skin. There was no trend for an increase in epidermal melanin content per unit area on Fontana-Masson staining. There was an age-associated decrease in the Ki-67 positive rate(p<0.001), the density of Ki-67 positive cells declined approximately 1.16% per decade in photoprotected skin(p<0.001). The number of S-100 positive cells declined approximately 4.4/mm width along the dermo-epidermal juction per decade in photoprotected skin(p<0.001). The expression of differentiation markers(keratin 1, involucrin, filaggrin, loricrin) were not different among the three age cohort groups. 2. With advancing age, there was an attenuation in the number and diameter of elastic fibers in the papillary dermis and an increase in the number and straightness of the same fibers in the reticular dermis. The collagen fibers are arranged in sparse bundles in disarray, and/or aggregates of loosely woven, straight fibers in the aged skin. There was an apparent, age-related decrease in the stainability of ground substances in the papillary dermis on colloidal iron staining. Conclusions : Our data documents semi-quantitative differences among three groups in intrinsically aged breast skin and provide the framework for future research to evaluate the ageing process.

8.Urethrotomy Under Endoscopic Direct Vision in the Management of Urethral Stricture.
Korean Journal of Urology 1985;26(3):231-236
28 times of Urethrotomy under endoscopic direct vision was made on 26 patients with urethral stricture. The results were as follows: l. Urethrotomy under endoscopic direct vision was highly useful for the primary management of any urethral stricture without associating with portion and length of stricture. 2. It could be easily repeated when the stricture recurred. 3. It was very safe, with few complications, 1 case of false passage and 2 cases of acute epididymitis and 2 cases of urinary incontinence.

9.Systems Development and Operational Strategies for Continuing Medical Education: II. Development of problem-based self-assessment format.
Korean Journal of Medical Education 1990;2(2):14-22
The basic premises in development of continuing medical education (CME) program demand to provide an equal opportunity for a11 practitioners and to plan a valid instructional design to meet the characteristics of adult education. Of a variety of identified problems with regard to implementation of CME programs for practicing physicians in this country, the most serious one is that majority of the current programs have aimed only for large city-based physicians and no effort has been made for those who are geographically away from the educational resources or those who could not participate because of their personal inconvenience. Furthermore, an additional critic raised among the learners is that most of CME programs have been instructed in a form of teacher-based or lecture-oriented didactic teaching. This paper describes a problem-based, self-assessment format as a possible tool for CME program primarily for those who practice in the rural areas. The program is characterized by combination of (1) self-instructional system using mailed educational materials, and (2) self-assessment system under a strictly guided instruction. Appropriate need analysis is the prerequisite of the format and is followed by mailing of educationally well-designed resource materials (reading assignment, workbook, video-tape, audio-tape, etc) and quiz items to facilitate the participating physicians to study the related areas upon their interest, and by close follow-up with comprehensive feedback on the returned answer sheets. Emphasis is given to the computer-based personal filing that is an essential administrative procedure for analysis of performance progress. It should be also equipped with advantages of adult educational principles in learning and evaluation process. The detailed operational procedures are described and educational significance is discussed in each step.
