Os subfibulare is a accessory bone arround the lateral maleolus, but it is different from many other accessory bones in foot and ankle in its development related to trauma and frequent symptoms of ankle instability. Accessory bone is a developmental anomaly which fails to unite to main secondary ossification center and usually asymptomatic. But os subfibulare is developed by recurrent ankle sprains in younger age or non-union of avulsion fracture of anterior talofibular ligament and causes instability of ankle. We experienced two cases of symptomatic os subfibulare in adolecents and report them with review of literatures.

1. A Case of osteosarcoma is reported which arose 8 years after synovima of the knee had been locally excised. The patient is a 51-year-old housewife who had received irradiation therapy upon her knee for 30 days post-operatively. Following irradiation, asymptomatic latent period lasted 8 years when mass appeared on the site, which was biopsied and diagnosed as osteosarcoma one year later. 2. This case generally suffices the McKennas criterias for irradiation-induced osteosarcoma, 3. It seems to be worthwhile to keep an eye upon the prognosis of this possible case of irradiation- induced osteosarcoma, which is largely reported to be very grave.

In order to investigate the efficacy and safety of oral cilazapril, a new angiotensin converting enzyme inhibitor, on essential hypertension, a single daily dose of 2.5 to 5.0mg cilazapril was administered in 30 hypertensive patients with diastolic blood pressure in the range of 95??15mmHg while off all other anti-hypertensive agents for 10 weeks. Blood pressure and heart rate were measured every 2 weeks. The complete blood count with platelet count, blood chemistry by SMA-12 including lactic dehydrogenase and serum electrolytes, and urinalysis were performed at 4th and 10th week of therapy. The electrocardiography was performed at the beginning and the end of treatment period. Any kinds of side effects were actively questioned by the examining physicians. The following results were obtained : 1) The mean age was 49.2 years, and the ratio of male-to-female was 1 : 1.3. 2) Blood pressure started to fall significantly within 2 weeks of treatment with cliazpril 2.5mg(M+/-S.E., 15.4+/-17.4mmHg vs 138.5+/-23.3, 100.3+/-6.2 vs 89.4+/-6.6, p<0.05), and after 6 weeks of treatment with a mean dosage of 2.84mg. diastolic blood pressure of all subjects was maintained below 90mmHg throughout the rest of trial. 3) Pulse rate or body weight were not significantly changed during the entire treatment period(69.3+/-6.0/min vs 10th week : 69.0+/-7.7, 64.7+/-7.4kg vs 63.6+/-6.7, p>0.05). 4) There were no significant changes in blood chemistry including blood sugar, cholesterol and electrolytes, except mild changes of serum creativine and alkaline phosphatase values. 5) Hematologic findings, urinalysis and electrocardiographic findings remained unchanged. 6)Side effects were mostly mild in nature without potentially serious episodes(dry cough : 20%, indigestion, headache, dizziness, in order), but there was 1 cases in whom the dosage was redyced due to postural hypotension. From the above results, cilazapril with the dosage of 2.5 to 5.0mg was effectvie and well tolerated in essential hypertensive patients with diastolic blood pressure of 95 to 115mmHg, and cilazapril seems to be appropriate for monotherapy of mild to moderate hypertensive patients.

Between Jan. 1990 and Sep. 1996, 462 renal allografts were carried out at the Ulsan University College of Medicine and Asan Medical Center. This study was undertaken to evaluate a clinicopathologic features, to document a relationship between dosage and duration of the corticosteroids, and to figure out a treatment strategy of avascular necrosis(AVN) of bone in 13 cases of AVN of the femoral head following renal transplantation. A control group of 15 cases were randomly selected among 462 cases of renal allografts to do a comparative study with 13 cases of AVN. The diagnosis of AVN of bone was made on the basis of plain radiographs and MRI or bone scan. 1) The incidence of AVN was 2.8%(13/462). 2) In entire cases, affected site of bone was the femoral head. The main clinical manifestations were hip joint pain, limitation of weight bearing and motion. The mean onset of first bone symptoms of AVN was 5.5 months(1~9 months). 3) Clinical parameters such as age, sex, type and duration of preoperative dialysis, type of donor, rate of body weight change, and duration of follow up had no relation with the prevalence of AVN. 4) The mean total doses of corticosteroids at 1, 3, 6, and 12months post-transplantation were not differ significantly between the two groups. 5) Biochemical parameters, such as BUN/Cr., Ca, /P, /ALP., AST/ALT, cholesterol, glucose, total protein, and albumin had no relation save the preoperative BUN, total protein. 6) The mean duration of diagnosis of this condition were 12.9 months(range, 9~31 months), 6.7 months(range, 1~12 months), 6.9 months(range, 1~14 months) by X-ray, MRI, and bone scan respectively. 4/12(33.3%) cases of AVN was diagnosed by magnetic resonance imaging(MRI) at the time of the first clinical bone symptoms. 7) In AVN group, conservative management were performed in 2 cases, core decompression in 7 cases, and total hip replacement arthroplasty(THRA) were performed in 4 cases of AVN of the femoral head. From this study, we could not illustrate the precipitating factors in transplant recipients using steroid following renal transplantation. We considered that prognosis of AVN depends entirely on early diagnosis using MRI or bone scan, and proper treatment according to the stage of this condition.

PURPOSE: The purpose of this study is to present the usefulness of arthrometer (KT-2000) in patients with anterior knee instability and to assist in evaluating an objective prognosis after anterior cruciate ligament reconstruction. MATERIAL AND METHOD: We analyzed the manual maximum anterior displacement, passive anterior displacement at 30Ib force and compliance index between 15Ib and 30Ib, measured by KT-2000 in 82 cases of patient who had unilateral anterior knee instability and 40 cases of volunteers, as control group, who had no history of knee injury. We used the Paired and Independent t-test for statistical analysis. RESULTS: In control group, the mean value of manual maximum anterior displacement is 0.8 +/- 0.9mm, passive anterior displacement, 1.4 +/- 1.3mm and compliance index, 1.1 +/- 1.1mm. In patient group, the mean value of manual maximum anterior displacement is 7.1 +/- 2.7mm, passive displacement, 6.1 +/- 2.6mm and compliance index, 3.8 +/- 1.8mm. We found that the patient group was revealed much higher degree of anterior displacement than the control group (p<0.005) . CONCLUSION: KT-2000 is objective and quantitative in diagnosis of anterior knee instability.

Spinal arachnoid cysts are a rare disease with an unknown origin. Because of their broad base, a total laminectomy with or without fusion has been the treatment of the choice. We encountered 5 patients with a spinal arachnoid cyst who were treated by recapping laminoplasty after pars osteotomy. This procedure has not been reported in Korea. All patients showed neurological recovery with no recurrence of the cyst. The findings on the stressed plain film confirmed bony union and stability of the posterior element.

Because nonspecific colonic ulcer is an unusual condition and varies markedly in clinical presentation and course, preoperative clinical diagnosis of nonspecific colonic ulcer is very difficult, But now, preoperative clinical diagnosis can he made by advent of colonofiberscopy. And, it is very important to diagnose this disease early, because late diagnosis make a poor prognosis. We report a case of nonspecific colonic ulcer diagnosed by repeated colonofiberscopy and treated with surgery.

We have evaluated the outcome of the high myopic patients who had been underwent cataract extraction with 0 diopter posterior chamber intraocular lens (PC IOL)implantation (15 eyes)and without PC IOL implantation (11 eyes), retrospectively.The average axial length was 31.1 mm and the average calculated diopter of PC IOL was +0.48 diopter.The preoperative corrected visual acuity (VA)had no statistically difference between the two groups.But the numbers of eyes that had postoperative corrected VA above 20/40 were 1 of 11 aphakic eyes and 7 of 15 pseudophakic eyes, and had significant difference (p<0.05).The after cataracts were found in 4 eyes of aphakic eyes and 1 eye of 0 diopter pseudophakic eyes.Among of them, 4 eyes of aphakic eyes underwent Nd:YAG laser posterior capsulotomy and not revealed the retinal detachment.So we thought that PC IOL implantation after cataract extraction in high myopic eyes could improve the visualacuity, decrease the incidence of after cataract and retinal detachment.

PURPOSE: Metastasis to the regional lymph nodes is the most important prognostic indicator in patients with colorectal cancer (CRC). The number of lymph nodes examined for adequate staging is still controversial. The aim of this study was to determine if the number of lymph nodes after curative surgery is associated with long-term outcome in patents with Dukes B CRC. METHODS: A retrospective analysis was performed in 174 consecutive patients with Dukes B CRC who underwent curative resection from 1990 to 1999. Patients were stratified according to the number of nodes examined as group A (less than 12 nodes) and group B (12 or more nodes). End-points were local and systemic recurrence and relapse-free survival. Comparisons between the groups were performed by Kaplan-Meier methods and chi-square test as appropriate. RESULTS: There were 115 men (66%). The mean number of nodes examined was 13.4 with the median of 11. No significant difference was found in the number of nodes examined between colon and rectum (16+/-10.6 vs. 13+/-10.0, P=0.675). However, the number of lymph nodes examined tends to be more in recent period of study and if the specimens were examined in the fresh status. With the median follow-up of 44 months, there were 5 local recurrences (2.9%), 22 systemic recurrences (12.6%), and 2 combined local and systemic recurrences (1.1%). Most of the recurrences were observed in group A (79%). The difference of 5-year relapse-free survival rates between the groups was also statistically significant (group A: 73.5%, group B: 91.7%, log-rank test, P=0.0114). The pT stage and number of lymph nodes examined were the independent variables associated with relapse-free survival in multivariate analysis. CONCLUSIONS: The number of lymph nodes examined has prognostic value in patients undergoing curative resection for CRC. Based on our analysis, we recommended at least 12 lymph nodes should be analyzed for accurate staging of CRC.
