The role played by synovial plica in internal derangement of the knee has been increased recently. A clinical application of arthroscopy of the one hundred eighty patients were performed, and eighteen patients with a symptomatic plica were successfully managed and followed by arthroscopic surgery at the department of orthopaedic surgery, Soon Chun Hyang University Hospital from May 1983 to May 1984. The results were summerized as follows; 1. Arthroscopy is the most accurate diagnostic and operative methods for the investigation of the incidence, pathology, clinical significance and treatment of the synovial plica. 2. The incidence of the mediopatellar plica in our view was 41% that is, 74 of 180 symptomatic knee. 3. Arthroscopy is a practical and valuable procedure with minimal associated morbidity or complication. 4. The increased accuracy of diagnosis help to avoid unnecessary operations and to be basic methods of treatment on a better knowledge of the pathology.

PURPOSE: The differentiation between renal cell carcinoma(RCC) and transitional cell carcinoma(TCC) is important due to the different methods of treatment and prognosis. But occasionally it is difficult to draw a distinction between the two diseases when renal parenchyme and renal collecting systems are invaded simultaneously. MATERIAL AND METHOD: We reviewed CT scans of 37 cases of renal cell carcinoma and 12 cases of transitional cell carcinoma which showed involvement of renal parenchyma and renal sinus fat on CT. Retrospective analysis was performed by 3 abdominal radiologists. Check points were renalcontour bulging or reniform shape, location of mass center, intact parenchyme overlying the tumor, cystic change, calcification, LN metastasis, vessel invasion, and perirenal extention. RESULT:There were renal contour bulging due to the tumor mass in 33 out of 37 cases of renal cellcarcinima, wherea and nine of 12 cases of transitional cell carcinoma maintained the reniform appearance. This is significant statiscal difference between the two(p<0.005). Center of all TCCs were located in the renal sinus, and 24 out of 35 cases of RCC were located in the cortex(p<0.005). Thirty-six out of 37 cases of RCC lost the overlying parenchyma, whereas 4 out of 9 cases of well enhanced TCC had intact overlying parenchyma(p<0.005) RCC showed uptic change within the tumor mags in 31 cases which was significanity higher than the 4 cases in TCC(p<0.05). CONCLUSION: CT findings of renal cell carcinoma are contour bulging, peripheral location, obliteration of parenchyma, and cystic change. Findings of transitional cell carcinoma are reniform appearance, central location within the kidney, intact overlying parenchyma, and rare cystic change.

BACKGROUND: Osteoporosis results from bone loss due to menopause [estrogen(E) deficiency] and aging. Initial skeletal effect of menopause is accelerated bone resorption with an increase in seurm calcium(Ca) and compensatory but inadequate bone formation. Secretion of parathyroid hormone(PTH) is suppressed at this time. Postmenopausal osteoporosis results in fractures predominantly of trabecular bone, i.e., vertebra. With aging, secondary hyperparathyroidism by low serum Ca and vitamin D deficiency superim poses. Senile osteoporosis produces hip fractures, area of cortical bone. The aim of this study was to- examine the association of vitamin D[25(OH)D] and intact(i) PTH with bone mineral density(BMD) after controlling for suggested confounding factors, and the possibility of low serum vitamin D and high serum iPTH concentration could impact bone loss in Korean postmenopausal women. METHODS: Data from 188 postmenopausal Korean women aged 42 to 69 were analyzed through BMD, serum 25(OH)D, iPTH, Ca, phosphorus(P), alkaline phosphatase(ALP) and clinical characteristics. Factors affecting BMD was determined by Pearson correlation and the relationship between lumbar and femoral neck BMD and vitamin D[25(OH)D] and iPTH was assessed by multiple regression analysis after adjus- ting for suggested confounding factors. RESULTS: Lumbar and femoral neck BMD, serum Ca, P were decresaed and serum iPTH was increased with aging. In Pearson`s correlation, significant contributing factors to lumbar BMD was age, height, weight, menarche, year since menopause(YSM) and ALP. And significant contributing factors to femoral neck BMD was age, height, weight, menarche, YSM and iPTH. No relationship could be demonstrated between serum vitamin D[25(OH)D] and lumbar and femoral neck BMD. How ever, after controlling for potential confounding factors, a correlation was found between vitamin D[25(OH)D] and both of lumbar (p=0.013) and femoral neck BMD(p=0.077). iPTH was inversely related to femoral neck BMD(p=0.004) only in multiple linear regression. CONCLUSION: Serum vitamin D[25(OH)D] was influencing both of vertebral and femoral neck BMD, which suggests a significant role of vitamin D deficiency in the pathogenesis of postmenopausal osteo- porosis. In age related remodeling and loss of bone, increased serum iPTH might have additive role in cortical bone of femur. These findings suggest that vitamin D is very important for optimal bone health and a deleterious effect of increased iPTH on cortical bone loss. Adequate calcium and vitamin D status have to be maintained to prevent osteoporosis in postmenopausal Korean women.

A clinical application of the arthroscopy to the three hundred symptomatic knees were performed, and seven knees with a symptomatic seprated suprapatellar bursa were successfully managed and followed by arthroscopic surgery at the Department of Orthopaedic Surgery, Soon Chun Hyang University Hospital from May 1983 to May 1985. The results obtained are as follows; 1. Separated suprapatellar bursa may cause some internal derangement of the knee. 2. The incidence of the separated suprapatella bursa in our view was 5% that is, of 300 symptomatic knees. 3. Separated suprapatellar bursa may have to be excised under arthroscopy.

Kimura's disease is a granulomatous disease which develops in the skin, subcutaneous tissues and lymph nodes and is characterized histologically by the presence of lymphoid follicles, vascular proli- feration and infiltration with eosinophils. The disease shows geographical predilection to Japan, China and South East Asia. The exact etiology and pathogenesis remain uncertain. Some patients had proteinuria or nephrotic syndrome. We have recently experienced the superimposed oliguric acute renal failure associated with Kimura's disease in a male patient with chronic renal failure who had been managed conservatively. Inguinal lymph node biopsy revealed Kimura's disease. He recovered from acute renal failure after being treated with hemodialysis and prednisolone. Lymphadeno- pathy and fever subsided with steroid treatment. We report a case of Kimura's disease which was complicated by acute renal failure in the patient with chronic renal failure.

Cystic mesothelioma of the peritoneum is a very rare tumor which has a clinically and histologically benign nature. It occurs predominantly in young to middle-ged women and tends to recur locally. It affects chiefly the pelvic peritoneum-articularly the cul-e-ac, uterus, and rectum. We report a case of cystic mesothelioma of the visceral peritoneum which was located anterior to the ascending colon. A 54-ear-ld female patient visited our hospital with a palpable tender mass in the right flank. A computed tomographic scan of the abdomen showed a multicystic mass with an enhancing wall and septum in front of the ascending colon. The patient underwent a right hemicolectomy, and the mass was completely removed. Grossly, the tumor consisted of a multilocular cyst containing clear, serous, or gelatinous fluid and partially solid areas. Microscopically, the solid areas were composed of fibrous tissue, and the lining cells varied from flattened to cuboidal cells with a strong positive reactivity for cytokeratin and mild positive reactivity for epithelial membrane antigen on immunohistochemical staining. These findings suggest that the tumor was mesothelial in origin.

BACKGROUND/AIMS: p53 mutation is the most common genetic abnormality in human cancers. However, although it has been reported that p53 overexpression in hepatocellular carcinoma (HCC) is associated with the aggressive behavior of tumor, the prognostic significance of p53 overexpression in HCC remains controversial. The aims of the present study were to examine the correlations between p53 overexpression and the clinicopathologic parameters of HCCs, and to determine the prognostic significance of p53 overexpression in HCC. METHODS: Immunohistochemical analysis of p53 overexpression was performed in 105 consecutive cases of HCC who underwent curative hepatic resection. Survival curves were calculated using the Kaplan-Meier method and multivariate analysis of outcome predictors for HCCs was assessed by logistic regression analysis. RESULTS: p53 overexpression was observed in 20 of 105 HCCs (19.0%). Multivariate analysis identified significant correlations between p53 overexpression and microvascular invasion (p=0.027), liver cirrhosis (p=0.035), 1-year survival rate (p=0.016), multiple tumors (p=0.014), and the presence of tumor capsule (p=0.010). The 2-year survival rate was poorer in patients without tumor capsule (p=0.043). CONCLUSIONS: Our results show a positive association between p53 overexpression and microvascular invasion in HCC, and indicate that p53 overexpression is a poor prognostic factor of survival, especially within 1 year after liver resection in HCC patients.

BACKGROUND: Hepatitis B is a worldwidely distributed disease. The hepatitis B prevalence of South East nations is reported to be higher than that of America or Europe. Korea is known to be one of high prevalent nation among Asia-Pacific nations. But hepatitis B prevalence in North Korea, separate from South Korea due to politics and ideology, is not reported. This study was performed using the data of North Korean defectors to estimate the prevalence of hepatitis B in North Korea. METHODS: We analyzed the data of 107 persons (98, mals, 9 females) who defected from North Korea and underwent screening exammination in a general hospital from July 1987 to March 1996. Twenty nine persons(25 males, 4 femals) were excluded because of incomplete data. The HBsAg test was carried out by reversed passive hemagglutination(RPHA) and the anti-HBs test was carried out by passive hemagglutination(PHA). The liver function tests were carried out by biochemical quantitative analysis method of Dimension. RESULTS: The study group were 73 males(93.6) and 5 females(6.4%). Mean age was 33.0+/-8.4 years and third decade was the largest as 35 persons(44.9%). The overall HBsAg positive rate was 15.4% and anti-HBs positive rate was 83.9%. Those who need vaccination was 51.4%. The only item amorg liver function tests which was statistically different by the hepatitis B viral marker groups was alkaline phosphatase. Mean total cholesterol was 176.4+/-38.0mg /dL. But no other item of liver function tests was statistically different in abnormal value by the hepatitis B viral marker groups. CONCLUSIONS: The overall HBsAg positive rate of North Korean defectors was much higher than that of South Korean and anti-HBs positive rate was much lower. So HBsAg positive rate of North Korean seems to be higher than that of South Korean. We think that a large study of hepatitis B for North Korean should be performed at every opportunity and take a measure to meet the situations.

PURPOSE: The aim of this study was to introduce a method of obtaining the oscillation graphs of the dental x-ray tube heads relative to time using an accelerometer. MATERIALS AND METHODS: An Accelerometer, Piezotron type 8704B25 (Kistler Instrument Co., Amherst, NY, USA) was utilized to measure the horizontal oscillation of the x-ray tube head immediately after positioning the tube head for an intraoral radiograph. The signal from the sensor was transferred to a dynamic signal analyzer, which displayed the magnitude of the acceleration on the Y-axis and time lapse on the X-axis. The horizontal oscillation of the tube head was measured relative to time, and the settling time was also determined on the basis of the acceleration graphs for 6 wall type, 5 floor-fixed type, and 4 mobile type dental x-ray machines. RESULTS: The oscillation graphs showed that tube head movement decreased rapidly over time. The settling time varied with x-ray machine types. Wall-type x-ray machines had a settling time of up to 6 seconds, 5 seconds for fixed floor-types, and 11 seconds for the mobile-types. CONCLUSION: Using an accelerometer, we obtained the oscillation graphs of the dental x-ray tube head relative to time. The oscillation graph with time can guide the operator to decide upon the optimum exposure moment after xray tube head positioning for better radiographic resolution.
