The origin of the popliteal cyst is the popliteal bursa and frequently combined with the intraarticular lesion. And open excision has been commonly used as a treatment. The authors reviewed 39 cases of popliteal cyst in 38 patients, mangaged with arthroscopic method at Department of Orthopedic Surgery, College of Medicine, Korea University Hospital from June 1989 to July 1993 and the following results were obtained. l. Among 39 cases, 35 cases(89.7%) were associated with intraarticular lesions of the knee joint; 25 cases(71.4%) were chondral injuries, 6 cases(17.1%) were meniscus tear, 2 cases(5.7%) were rheumatoid arthritis and 2 cases were plica syndrome. 2. 20 cases(51.2%) were shown to have the communication between cyst and joint. 3. During operation, position change of the patient and another draping was not necessary. And the blue stained wall enabled authors to remove more completely the popliteal cyst than other conventional operative procedures. 4. Becuase of the short skin incision, the operation time was saved and we were able to recommend early excercise of the knee joint and ambulation. The operative treatment of popliteal cyst with the arthroscopy is the one staged method to excise the cyst and to intervent the combined intraarticular pathology which develop the cyst, and is one of the recommendable method bacause of small skin incision, short hospitalization and early rehabilitation.

STUDY DESIGN: The authors analysed the recovery of clinical symptoms after percutaneous drainage and irrigation in pyogenic vertebral osteomyelitis. OBJECTIVES: To determine the role of percutaneous drainage and irrigation in pyogenic vertebral osteomyelitis. SUMMARY OF LITERATURE REVIEW: Pyogenic vertebral osteomyelitis is a relatively rare condition but its incidence is recently increasing due to common use of intravenous access devices and resultant nosocomial bacteremia. Management of the disease is not uniform and is controversial regarding the role of surgery and duration of use of antibiotics. At present, the role of percutaneous drainage of involved spines in treatment of pyogenic vertebral osteomyelitis is not well-known. MATERIALS AND METHODS: We report 3 cases of pyogenic vertebral osteomyelitis which were treated by continuous drainage with automated percutaneous lumbar discectomy device(APLD device) and draining tube after they haute failed to conservative treatment. APLD device, fluoroscopic guide, contrast media and continuous percutaneous draining tubes were used for this procedure. The percutaneous draining tubes were maintained for 7 to 11 days and each case was followed up for 6 to 10 weeks under admission. RESULTS: Symptoms were relieved 3 to 5 weeks after this procedure. The patients were followed up to 12 to 39 months and experienced no recurrence. CONCLUSIONS: Percutaneous drainage and irrigation with APLD device brought prompt and marked clinical recovery. It is indicated as a supplementary method to conservative treatment or in case of high operative risk patient due to poor general conditions. It has minimal invasiveness, short clinical course and low recurrence rate.

The purpose of this study was to investigate the possibility of distraction osteogenesis in membranous onlay bone graft on the mandible and to clarify the histology of bone repair during distraction osteogenesis in the membranous onlay bone in a dog model. Four dogs, 5 months of age at the beginning of the experiment, were used for this study. The zygomatic arch was exposed in the subperiosteal plane and the full-thickness zygomatic arch was harvested to 3 centimeters in length. The lateral surface of the mandibular body was exposed in the subperiosteal plane and the membranous onlay bone graft was performed with firm contact using screws. The osteotomy on the membranous onlay bone graft and underlying mandibular body was carried down week 1 in dog 1, week 2 in dog 2, week 3 in dog 3, and week 4 in dog 4 after membranous onlay bone graft. The external distraction device was applied to the mandibular body. Mandibular distraction was started 7 days after the operation at a rate of 1mm per day for a total of 10 mm distraction over 10 days. After completion of distraction, the distraction device was left in place for 6 weeks bony consolidation of the distracted area. Radiographs were carried out at 2 weeks, 4 weeks and 6 weeks after distraction. New bone between the native underlying mandibular segments was generated in the distracted zone in all dogs. The new bone between the native underlying mandibular segments was generated in the distracted zone in all dogs. The new bone between segments of membranous onlay bone graft was not generated in dog 1, but it was generated in dogs 2, 3 and 4. However, in dog 2 and 3, the new bone between segments of the distracted membranous onlay bone graft presented less firmness with fibrous tissue than that of the native underlying mandibular segment. Histologically, the distracted gap between segments of the membranous onlay bone graft was composed of much fibrous tissue in the central zone while activated osteoblastic cells formed new bone in the margins of the distracted gap in dogs 2 and 3. In dog 4, there were abundant osteoblastic activities in the distracted gap and the new bone appeared as nearly-normal cortical bone. In conclusion, these findings suggested that membranous onlay bone graft had an osteogenic capacity and that distraction osteogenesis was possible in membranous onlay bone graft.

The occurrence of sqamous cell carcinoma arising from epidermal cyst is unusual. A 54-year-old man with soft tissue mass on the back for 25 years presented an infiltrating squamous cell carcinoma within the wall of epidermal cyst. All tissue excised deserved to be examined to be axamined carefully in longterm epidermal cyst.

OBJECTIVE: Arrhythmogenic right ventricular cardiomyopathy(ARVC) is a progressive cardiac muscle disease characterized as progressive fibrofatty replacement of the right ventricle, severe ventricular arrhythmia, and sudden death. However, there is no report of ARVC as a cause of sudden death in Korea. METHODS and RESULTS: Postmortem studies were done to 115 cases of sudden unexplained death at department of legal medicine, school of medicine, Kyungpook national university in year 1999. We identified 7 cases(6%) of typical ARVC with no other identifiable cause of sudden death. The subjects included 5 males and 2 females, ranging in age from 19 to 41 years (mean 29.7 years). All were found dead at bed (5 cases) or workshop (2 cases). Five cases were fibrofatty types and two cases were fatty types. Right ventricular aneurysm, inflammatory infiltrates and left ventricular involvement were found in 4, 2 and 1 cases, repectively. Two cases had family history of sudden death before age 40. No one was suspected of having cardiovascular disease or ARVC before death. CONCLUSION: These findings indicate that ARVC in Taegu-Kyungpook area may be more frequent than previously thought. ARVC may be a major cause of sudden unexplained death.

To evaluate the tissue expression rate and pattenr of HBsAg and HBcAg in tumors and peritumoral livers, an immunohistochemical study was undertaken on 47 surgically resected hepatocellular carcinomas(HCCs). The results are as follows. 1. Patient's sera were positive for HBsAg in 40 cases(85.1%). In the remaining 7 cases, the tumor and peritumoral liver expressed neither HBcAg nor HbSaG, suggesting that they were caused by other etiologies than hepatitis B virus. 2. The peritumoral liver had HBsAg and HBcAg in 95.0% and 27.5% among the 40 cases, respectively. But the tumor expressed HBsAg in 50.0% and HBcAg in none. 3. The expression of HBsAg within the tumor and both HBsAg and HBcAg in the peritumoral liver tended to be more frequent in the pretreated cases before surgery. 4. Edmondson-Steiner grade IV tumors revealed a lower expression rate of HBsAg than the low grade tumors(p<0.05). Incases with cirrhosis at peritumoral tissues, HBcAg was less frequently found than in those without cirrhosis. The majority of tissue HBsAg and HBcAg was represented as groups of positive cells. These results suggest that, during the development and progression of HCCs, the HBcAg containing cells are repeatedly removed and the HBcAg negative cells are selected, because cellular expression of HBcAg is the target of host immune response.

Recent studies suggest that apolipoproteins may be better predictor of ischemic heart disease than are plasma lipids, such as total cholesterol and high density lipoprotein cholesterol(HDL-C). To examine this hypothesis, plasma levels of major lipids and major apolipo-proteins were measured and their derivatives were calculated in 30 male patients with ischemic heart disease(16 angina pectoris and 14 old myocardial infarction) and 30 age-matched male healthy controls. Plasma levels of lipids were obtained by conventional methods and apolipoproteins by Rocket immunoelectrophoresis. Levels of HDL-C, HDL2-cholesterol(HDL2-C), and apolipoprotein-AII, and ratios of HDL-C/total cholesterol, HDL2-C/total cholesterol, and apolipoprotein-AI/apolipoprotein-B were lower in the group of patients than in controls. Levels of low density lipoprotein cholesterol(LDL-C) and apolipoprotein-B, and ratios of lDL-C/HDL-C and apolipoprotein-AI/apolipoprotein-AII were higher in the group of patients. There were no statistically significant differences in the levels of total cholesterol and apolipoprotein-AI between the two groups. Stepwise discriminators analysis showed that apolipoprotein-B and apolipoprotein-AII were better discriminators than plasma lipids for identifying those with ischemic heart disease. One could correctly classify 78% of the cases by using the levels of the two apolipoproteins. By using the level of apolipoprotein-B, one could correctly classify 73% of the cases. There were no correlations between the levels of total cholesterol and HDL-C in the controls whereas there were positive correlations between the levels in the group of patients. In conclusion, this study showed that apolipoprotein-B was the best single discriminator for identifying the patients with ischemic heart disease, followed by apolipoprotein-AII.
