PURPOSE: With the process of neoangiogenesis being linked to the growth and metastasis of various tumors, anticancer therapeutics with a basis in the suppression of neoangiogenesis has recently been receiving attention. In this study, we tried to clarify the immunoreactivities of vascular endothelial growth factor (VEGF), major angiogenic inducer and thrombospondin-1 (TSP-1), major angiogenic inhibitor in human Wilms' tumor and its clinicopathological significance. MATERAILS AND METHODS: Utilizing immunohistochemical staining, we assessed the immunoreactivities of VEGF and TSP-1 in archival tissues of 29 Wilms' tumors and 25 normal kidneys. Also, we assessed the relationship between expression of each factor and clinicopathological parameters in 29 cases of Wilms' tumors. RESULTS: Immunoreactivities of VEGF and TSP-1 were detected mainly in the cytoplasm of the tubular cells in normal kidneys. In Wilms' tumors, whereas VEGF was detected in the cytoplasm of the tumor cells and peritumoral stromal tissues, but TSP-1 only in the peritumoral stromal tissues. Immunohistochemical expression patterns of each factor were divided into two groups according to the area of immunoreactivity (negative:<10%, positive: > OR =10%). VEGF immunoreactivity was detected in 25 (100%) normal kidneys and in 20 (69%) Wilms' tumors. However, TSP-1 immunoreactivity was detected in 24 (97%) normal kidneys and in 3 (10%) Wilms' tumors. Therefore, although no significant difference was observed between the expressions of VEGF and TSP-1 in normal kidney, the TSP-1 immunoreactivity was significantly lower than VEGF immunoreactivity in Wilms' tumors. A relatively higher rate of positive expression of TSP-1 was observed in the patients with no demonstrable lymph node metastasis. Also, as for the VEGF, maximal diameter of the tumor was larger in the positive expression group. However, it proved otherwise for TSP-1 as the negative expression group demonstrated tumors with larger maximal diameters. CONCLUSIONS: Our study demonstrated that the TSP-1 immunoreactivity was significantly lower than VEGF immunoreactivity in Wilms' tumors, and disease progression has a tendency to be found in the VEGF-positive cases and TSP-1 negative cases. We suggest that the growth and metastasis of Wilms' tumor may be influenced mainly by TSP-1 decrease rather than VEGF increase.

BACKGROUND: Diet and weight concerns are commonplace and almost accepted features of life for girls during adolescence. Until recently, younger age groups haue largely been ignored, as these concerns were thought to be a product of pubertal development and sexual maturity. Girls under the age of fifteen therefore, have been assumed to be free of the pressures experienced by adult women. However, this belief is now hard to sustain. The object of the present study was to investigate the self-perception and body shape satisfaction in different weight categories of boys and girls aged 12-years old in Korea. METHODS: In May, 1995, one hundred and sixty seven boys and one hundred and twenty girls from two schools in Seoul completed assessments of body-esteem, self-esteem, body shape preference. The children's body weight and height were also measured. RESULTS: The heaviest children expressed the most discontent, having a low body-esteem, a desire for thinness. By the age of 12, girls boys already differ in their body shape satisfaction and differ in their body shape aspirations. There was a significant effect of weight category on the children's body esteem(boys(P =.005), girls(P=.0001). Children in both extreme categories, under-and over-weight, had lower body-esteem scores than those in other weight categories. However, it was the overweight children who had the lowest. reported body-esteem. Body esteem was highest among girls in the 'slightly underweight' category and highest among boys on the 'average weight' category. There was no effects of either weight category or gender on the childrens appraisal of self-esteem. A comparison of the points chosen on the silhouette scales to reflect current and preferred body shapes revealed clear gender differences. Of the girls, 63% placed their preferred body shape at a point thinner than their currently perceived shape, while only 15% chose a broader figure. In contrast,, 41% of the boys rated their preferred figure as broader than their current perception, and 37% as thinner than their current perception. CONCLUSIONS: This study has noted a relationship between body weight and self-perception in 12-year old children. The heaviest children expressed low body-esteem, a desire for thinness. This pattern was more characteristic of girls than boys. Even at this age, well before they have completed physical maturation, girls are aspiring to a body shape which is thinner than their average. This discontent experienced by the heaviest children on this sample was apparent in their lower body-esteem and the distance between their current and preferred body shapes. The girls preference was for thinness, while in the boys it was for a body shape which was broader than their current shape. From their responses, it would appear that the boys' desire was not for fatness, but for a more athletic and muscular build.

OBJECTIVES: This study was performed to investigate the relationship between age of onset in late-life depression and T2 hyperintensities observed in the brain MRI, we tried to see part of pathophysiology of late-life depression. METHOD: The subjects consisted of 18 patients whose first depressive episode occurred before age 50, and 20 patients whose first depressive episode occurred after age 50 years, and 20 agematched controls. Depressive patients were diagnosed according to DSM-IV. Established hyperintensity rating systems were used to analyse the T2 weighted images and blood pressure, cholesterol level, DM, EKG were measured to compare the relationships. RESULTS: 1) Signal hyperintensities on T2 weighted image were more severe in late-life depressive patients whose first depressive episode after age 50 (p<0.05) and there is no significant difference between patients whose first episode before age 50 and age-matched control subjects. 2) Mild signal hyperintensities were observed in all elderly depressed patients and control subjects, but severe hyperintensities were observed in late-onset depression. 3) Signal hyperintensities were related to age, hypertension, blood cholesterol level (p<0.05). CONCLUSION: The late onset depressive patients had more white matter hyperintensities on T2 weighted image than early onset depressive patients. this results support previous hypothesis that white matter change is the important biological factor of late-onset elderly depression and old age, hypertension, hypercholesterolemia may be associated with signal hyperintensities.

We performed a retrospective analysis of twenty-four consecutive hip arthroplasties (Total Hip Arthroplasty 18, Bipolar Arthroplasty 1, Cup revision 5) during which intraoperative frozen sections were analyzed to identify the occult active infection. We also reviewed the data such as laboratory findings (ESR, CRP), intraoperative culture, hip joint sonographic evaluation and permanent histologic section. Among the twenty-four patients those who received hip arthroplasties, 10 cases received revisional hip arthroplasties due to painful hip prosthesis loosening, 9 cases with infected hip prosthesis, 3 cases with infection after open reduction and internal fixation due to hip fracture and 2 cases with septic hip sequelae. Intraoperative frozen section had been obtained during staged revisional hip arthroplasties to determine the presence of active infection. We considered positive for infection if it shows more than 10 PML/HPF (Polymorphonuclear leukocyte /high power field) in at least 5 distinct microscopic fields from intraoperative tissue frozen section and postponed implantation of prosthesis. If it shows less than 5 PML/HPF, we performed revisional hip prosthesis implantation. We decided the implantation based on patient's condition, laboratory findings and intraoperative tissue conditions if it shows between 5 and 10 PML/HPF from intraoperative frozen section. At last follow up, 20 of 21 patients who had a revisional hip arthroplasties as below 10 PML/HPF from intraoperative frozen section remained free of infection (Specificity; 95%). We concluded that analysis of the intraoperative frozen sections is a reliable predictor as a guide to sepsis for the successful hip joint arthroplasties.

A case of carcinoma of the parathyroid gland causing hyperparathyroidism was experienced at the department of orthopaedic surgery, C.A.F.G.H. This patient, a 23 years old male, had complained of a left shoulder pain during the past 3months. And weakness of the lower extremities causing walking disturbance, multiple bone pain, and polyuria had occurred sinoe one month before admission. Physical examination revealed a hard palpable mass in the right anterior region of the neck. Radiologic examination revealed subperiosteal bone resorption in phalanges of the hands and feet, generalized osteoporosis and cystic lesions, and pathologic fracture of the ribs, left humerus, and left femur. Laboratory studies demonstrated hypercalcemia, hypophosphatemia, increased alkaline phosphatase and PTH, hypercalciuria, and hyperphophaturia. Sonogram and C-T scan of the neck revealed a mass in the right inferior portion of the thyroid. Rib biopsy revealed the findings of ostitis fibrosa cystica, and parathyroid gland and regional lymph node biopsy revealed a parathyroid carcinoma with regional lymph node metastasis.

The chondrogenic potential of free autogenous periosteal grafts for osteochondral defects was investigated at the Department of Orthopaedic Surgery, Yonsei University, Wonju College of Medicine. Five millimeter diameter of circular full-thickness defects were made in patellar groove of both femur in 64 adolescent rabbits and the rectangular periostei, prepared from the proximal tibiae, were placed over the defects of patellar groove and sutured(cambium layer, facing joint surface) and the rabbits were allowed to move actively. A serial gross and histologic examinations of neochondrogenesis were done during 8 weeks. The results were as follows. l. At 2 weeks after operation, neochondrogenesis was hardly seen either in the graft group or in the control group. The defects were partially filled with some fibrous tissue. 2. After 6 weeks of operation, all defects in the graft group(postop 6 weeks and 8 weeks) were filled with hyaline cartilage cells but only 38% (postop 6 weeks) and 44% (postop 8 weeks) of the control group were filled with hyaline cartilage cells. 3. The cartilages, formed at 6 and 8 weeks, were more mature and better than those formed at 4 weeks. 4. The newly formed hyaline cartilage of the graft group filled the defect earlier and were better than those of the control group. 5. The chondrocytes in the newly formed tissue were originated from the cambium layer of periosteal grafts. 6. Free autogenous periosteal grafts can repair a full-thickness defect in a joint surface by producing tissue that resembles articular cartilage grossly and histologically.

BACKGROUND: Pneumonia is the most common cause of death among patients with infectious disease in Korea. However, studies of pneumonia with septic shock in patients presenting to the emergency department are limited. The aim of this study was to investigate the prognostic factors associated with pneumonia with septic shock in patients presenting to the emergency department. METHODS: From January 2008 to September 2014, patients with pneumonia with septic shock admitted through the emergency department were retrospectively examined. RESULTS: Of the 561,845 patients who visited the emergency department, 398 were admitted for pneumonia with septic shock. The 28-day mortality rate in these patients was 36.4%. The independent prognostic factors were old age (>70 yrs) (odds ratio [OR], 2.42; 95%, confidence interval [CI], 1.35-4.32), Acute Physiology and Chronic Health Evaluation (APACHE) II score (OR, 1.04; 95% CI, 1.01-1.08), leukopenia (OR, 3.63; 95% CI, 1.48-8.94), prolonged PT-INR (OR, 2.53; 95% CI, 1.41-4.54), and hypoxemia (OR, 2.88; 95% CI, 1.30-6.38). CONCLUSIONS: A poor prognosis of patients with pneumonia is associated with old age (>70 yrs), increased APACHE II score, leukopenia, prolonged PT-INR, and hypoxemia.
