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 authors developed a computer program for use in report printing as well as data storage and retrieval for the gastrointestinal endoscopy service. This program used IBM PC XT and was written in dBASE III plus language. We applied the automatic SNOMED coding method, which is one of the most efficient and accurate method of computerization of medical data. The working sheet which contained the results of previous endoscopic studies could be printed during registration. The dBASE word processor enabled issuing of the formal report of endoscopic result, and the data storage was carried out during the typewriting of the report. Two kinds of data files were stored in the hard disk; the temporary file contained full informations and the permanent file contained patients identification data and SNOMED code. Searching of a specific case was performed by chart number, patients name, date of study, or SNOMED code within a second. All the cases were arranged by SNOMED codes of procedure, topography and morphology codes. Every new data was copied to the diskette automatically. with which data could be restored in case of hard disk failure. The main advantages of this program in comparison to the large main frame computer system are low price, flexibility and easy accessibility. Based on our experience (including surgical pathology department, radiology, clinical pathology), we assume that this program may fit every endoscopy room where there are less than 20,000 cases per year.

A 62-year-old male was admitted for evaluation of a mass shadow on chest film. Chest PA showed 7×5cm lobulated homogenous mass in right upper medial area of lung. On chest computed tomography, there was a Barge irregularly lobulated mass with central necrotic low density area in apical segment of right upper lobe. Right upper lobectomy of the lung was performed. Partial adhesion to parietal pleura of posterior mediastinum and severe adhesion to right upper apicoposterior segment was found during the operation Microscopic and ultrastructural studies(including immunocytochemical stains) of the mass revealed malignant fibrous histiocytoma.

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.

The increasing number of patients with depression is a serious social issue in contemporary Korean society. To fully understand the pathophysiology of depression, this paper reviewed how depression affects the decision making process of humans. Various recent studies in behavioral economics, mathematics, medicine, and neurobiology have shown how humans make decisions and how emotional disturbances, such as depressive disorder, affect this process. There has been great progress in behavioral economics during this decade, and numerous experiments have been designed to evaluate decision making process in humans. In general, economic decision making is evaluated using the Iowa Gambling Task, and social decision making is assessed using the ultimatum game. Numerous research studies have analyzed the performance and reaction of patients with depression in these games. As a result of the advancement of neurophysiology, research has successfully identified the part of the brain that causes the specific results of tests being conducted on patients with depression. Meanwhile, computational neuroscientists have established decision making models based on bayesian framework. These models also match with the neuroanatomy. Although a large part remains unclear, researchers look forward to achieving a better understanding in depression by analyzing the distinct patterns of responses that patients under depression show in the experiment of behavioral economics.
