PURPOSE: To describe the MR findings of simple bone cyst. MATERIALS AND METHODS: We analyzed the signal intensity of the cystic contents, their margins, and internal septae, and the presence of bony fragment and pathologic fracture, and enhancement patterns in MRI of 10 pathologically confirmed simple bone cysts. RESULTS: On MR imaging, the cystic contents were of homogeneously low signal intensity on T1WI and high signal intensity on T2WI in nine cases and fluid-fluid level was seen in one case. The cystic margins were dark in all sequences. There were not any fragment in the cysts. Among the four cases with pathologic fracture, one case had fluid-fluid level and two had some areas of enhancement in the cyst or adjacent soft tissue. All nine cases with gadolinium enhancement showed thin rim enhancement along the inner margin of the cysts and internal septae. CONCLUSION: Homogeneous fluid-like signal intensity of cystic content and thin rim enhancement of margin and internal septae in MR imaging are believed to be helpful in the diagnosis of simple bone cyst.

OBJECTIVES: The TGF-Beta1 (transforming growth factor-Beta1 ), which has been shown to inhibit cellular proliferation in vitro as a growth regulator, has been demonstrated to enhance tumori-genicity in vivo. The proteolytic processes of cancer are thought to be the crucial point in tumor invasion and metastasis, mainly by matrix metalloproteinases.(MMPs) We investigated the serum TGF-Beta1 and MMP-2 levels in patients with cervical cancer in contrast to those of normal, patients with benign myoma, and cervical intraepithelial neoplasia (CIN). And we questioned whether these serum levels are different according to the therapy of cancer or not. METHODS: We measured serum TGF-Beta1, MMP-2 concentrations by ELISA in 34 patients with cervical cancer, as well as 5 normal volunteers, 14 patients with benign myoma and 23 patients with CIN. Especially in 7 patients with cervical cancer, we measured serum TGF-Beta1, MMP-2 levels before and after therapy. RESULTS: The serum TGF-Beta1 levels in patients with cervical lancer(37.8 +/-15.4pg/ml) were significantly lower than those of the patients with CIN(46.2+/-9.2pg/ml)(p<0.05). But there is no differences among the serum MMP-2 levels in the patients with cervical cancers(680.30+/-116.6pg/ml), CIN(715.2+/-150.0pg/ml), and benign myoma(682.4+/-112.5pg/ml)(p>0.05). Patients undergoing cancer therapy did not have different values of serum TCF-Beta1 and MMP-2 levels as those without cancer therapy.(p>0.05) CONCLUSION: So we suggest that serum TGF-Beta1 may be helpful in differential diagnosing cervical cancers from CIN.

Rapid and accurate management is necessary for the emergency patients, but there is a few comprehensive and analyzed references about them and still the definition and the criteria of the urologic emergency are not defined. So a clinical observation was made on 382 patients, admitted to the Department of Urology through the emergency room of the Severance hospital during 5 years from January, 1972 to December, 1976. They were observed as following orders; annual, age, sex, symptoms, emergency managements, diagnostic procedures, diagnoses, associated diseases, and mortality rate etc. The results are as follows: 1. Urologic emergency patients were 382 (male 265, female 117). They were 1.4 % of the patients admitted through the emergency room, and 19.3% of the in-patients of the Department of Urology. 2. Symptoms and signs of the urologic emergency were pain (209 cases), gross hematuria (48 cases), acute retention (42 cases), acute genitourinary infection (38 cases), genitourinary injury (66 cases), shock (13 cases), and uremia(24 cases). 3. I.V.P. was the most common diagnostic procedure, but bone X-ray and the cystourethrogram were more common in genitourinary injury. 4. Emergency managements were performed in 227 cases. Pain control was most common (52t), then indwelling of the Foley catheter and transfusion were next. 5. In pain, flank or abdominal pain was most common (191 cases) and the most common cause. was lower 1/3 ureteral stone. 6. The causes of the gross hematuria were genitourinary tumor (11 cases), calculi(10 cases), acute cystitis(9 cases), and acute pyelonephritis (7 cases). 7. Acute retentions were commonly developed in old aged men and the most common cause was B.P.H. (42. 9%), then urethral stricture (23. 8%). 8. Acute genitourinary infections were most common in 3rd decade women. 9. Genitourinary injuries were most commonly occurred in the spring (34. 8%). The most common cause was kick or blow (43.9%) and the most common organ was urethra (40%). The most common combined injury was pelvic bone fracture (36. 8%). 10. The causes of the shock were genitourinary injury(84.6%) and bladder tumor (15. 4%). 11. The most common cause of uremia was genitourinary tumor (25%), then ureteral stricture (20. 8%). 12. In 30 cases, the presumptive diagnoses were different from the definite diagnoses. 43.3% of them were suspected as urinary calculi, but confirmed as acute pyelonephritis, ureteral stricture and tumor etc. 13. Associated diseases were common in old aged patients and cardiovascular (33%) or respiratory diseases (28.4%) were common. 14. Conservative treatment was most commonly performed, but suprapubic transvesical prostatectomy was more common in acute retention. 15. 7 patients were died and the mortality rate was 1.8%.

OBJECTIVES: Angiogenesis is a critical factor in the growth, progression, and metastatic spread of solid tumors. Angiogenic factors are soluble molecules released by the tumor itself and are able to induce an angiogenic response. Vascular endothelial growth factor(VEGF) is a multifunctional cytokine that has been shown to be an important regulator of tumor angiogenesis. The aim of this study was to determine the value of serum VEGF levels in the diagnosis of ovarian cancer and in the differential diagnosis of adnexal masses. And we questioned whether the serum VEGF levels are related to cancer stages and prognosis of patients. METHODS: Serum samples were taken from 85 patients; healthy women(n=15), the patients with benign ovarian cyst(n=36), and the patients with ovarian cancer(n=34). The concentration of VEGF, CA-125, and CA 19-9 were determined in the serum of each patients before and after treatment with an enzyme linked immunoassay(EIA), RESULTS: There are statistical differences among the serum VEGF levels in patients with ovarian cancer(491.5+/-335.6 pg/ml), and benign ovarian cyst (247.7+/-183.6 pg/ml)(p<0.05). The patients undergoing cancer therapy had lower values than those without cancer therapy(p<0.05). The serum VEGF levels were not correlated with the cancer stages and histologic types(p>0.05) CONCLUSION: The serum VEGF level appears to be a helpful tool in the differential diagnosis of ovarian cancer and may help in predicting the therapeutic effects of patients with ovarian cancer.
