Clinical study was carried out on the 64 hemodialysis patients(HD) with chronic renal failure who had been treated from December 1992 to July 1993 in Yeungnam University Hospital. The following results were obitained. In hematologic parameters, MCH was 28.8±2.0pg, and MCV was 92.4±4.7fl. Result revealed normochromic and normocytic anemia. Mean values of serum ferritin were 657.4±292.0ng/ml in men and 511.5±370g in women. Mean values of serum iron were 145.5±63.7µg/dl. Mean values of transferrin saturation was 61.6±28.4%. Serum frerritin, serum iron and transferrin saturation were higher in HD group than normal reference. In erythropoeitin treatment group, Hb and Hct were significantly higher than non-erythropoietin treatment group. Amount of transfusion was significantly higher in non-erythropoietin treatment group than erythropoeitin treatment group(p<0.05). Values of iron, transferrin saturation were significantly higher in abnormal liver function test(LFT0 hemodialysis group than normal LFT group(p<0.05). Transfusion amounts revealed positive correlation with ferritin(r=0.4675), transferrin satruation (r=0.3823) and iron(r=0.3386) (p<0.05).

PURPOSE: To evaluate the diagnostic value of magnetic resonance(MR) imaging in the differentiation of benign and malignant soft tissue masses. MATERIALS AND METHODS: MR examination of 47 patients with pathologically proven soft tissue masses were reviewed. This series included 19 malignant and 28 benign masses of upper and lower extremities, body, and neck. Lesions were evaluated for their margin, signal intensity and homogeneity, pattern and degree of enhancement, involvement of the adjacent tissue, and degree of surrounding edema. RESULTS: Sixteen of benign lesions(57.1%) had well-defined and smooth margin. The tumor margin was irregular in nine lesions(47.4%), however, smooth margin was noted in five cases(26.3%) of malignant lesions. On T2-weighted images, signal inhomogeneity was noted in 84% of malignant lesions and 32% of benign lesions. On Gd-DTPA enhancement study, all malignant lesions(n=18) showed enhancement and 89% showed heterogeneously enhancing pattern. Neurovascular involvement was observed more often in malignancy(n=7) compared to benign lesion(n=1). Direct invasion of the adjacent bone was noted only in malignant lesions(n=3). Surrounding edema was revealed in two benign and 11 malignant lesions. CONCLUSION: MR imaging appears useful for differentiating malignant and benign lesions by identifying tumor margin, signal homogeneity of tumor, pattern and degree of enhancement, involvement of adjacent tissue, and surrounding edema. The nature of the lesion can be determined in the majority of cases although no unique criterion to differentiate benignancy and malignancy is identified.

PURPOSE: Results of 181 percutaneous needle aspiration biopsies performed with an 18-gauge needle during a period of 3 years were analyzed to determine efficacy and safety of the procedure. MATERIALS AND METHODS: Biposies were performed in patients that could not be diagnosed by bronchoscopy or sputum cytology. The biopsy procedure with 18-gauge Crown needle was guided by fiuoroscopy. The biopsy specimen placed in 10% formalin solution were histologically confirmed. RESULTS: In 160 patients(89%), the positive diagnosis was made by percutaneous needle aspiration biopsy. There were 153 lung lesions(120 malignant and 33 benign lesions) and 7 mediastinal lesions. the diagnostic accuracy of malignant and benign disease was 91% and 80% respectively. Complications included pneumothorax(n=11) and hemothorax(n=l):six of them required treatment with chest tube and the remainder showed spontaneous resporption. CONCLUSION: PCNB with an 18-gauge needle provided a reliable, relatively safe diagnostic tool to establish the diagnosis of both malignant and benign chest lesions.

Cervical pregnancy is a rare form of ectopic gestation in which the blastocyst implants in the cervical mucosa below the histologic cervical os. Because of the serious vaginal bleeding, hysterectomy was usually done in the management of cervical pregnancy. Howerver, conservative treatment is desirable for women who want to be pregnancy in the future. Methotrexate has been utilized recently for conservative management of cervical pregnancy. We report a case of cervical pregnancy which was treated succesfully with intramuscular methotrexate injection.

We report a case of 70-year-old woman who had bilateral coronary arteriovenous fistula(CAVF) and treated with percutaneous transcatheter coil embolization. Enlarged LV and reduced global LV systolic function were demonstrated on transthoracic echocardiography. Coronary angiography revealed a large coronary arteriovenous fistula from the right coronary artery to the main pulmonary artery and a small fistula from the left coronary artery to the main pulmonary artery. Percutaneous transcatheter coil embolization for CAVF from the right coronary artery to the main pulmonary artery was successfully performed with symptomatic improvement.
