A 29 year old woman with unresectable leiomyosarcoma of the inferior vena cave extending into the right atrium of the heart was presented. The upper and middle inferior vena cava involved and there were both intrinsic and extrinsic tumor growth components. The diagnosis was made by a combination of radiological studies including ultrasound, CT, inferior vena cavography and arteriography and the diagnosis was confirmed by ultrasound guided rumor biopsy. The clinical and radiological presenting features were reviewed.

PURPOSE: To evaluate effectiveness of oblique approach under biplane fluoroscopic guidance in transthoracic fine needle aspiration biopsy. MATERIALS AND METHODS: Fourteen consecutive patients underwent transthoracic fine needle aspiration biopsy for subcarinal lesions. Subcarina was the only accessible biopsy site in 13 patients. Subcarinal biopsy was performed to determine the presence of metastasis in an enlarged subcarinal lymph node in the remaining one patient. Before biopsy, we evaluated the size and location of the lesion on preliminary plain chest X-ray film and CT scan. Under dual projection fluoroscopic guidence, biopsy was performed through right posterior intercostal space with the patient prone by using oblique approach. On 15 degree LAO projection the needle was directed to the area anterior to the spine and advanced to the line extending through the posterior wall of the main bronchus. RESULTS: Cytologic diagnosis was made in 12 out of 14 patients(accuracy 85.7%). The final diagnosis consisted of 5 squamous cell carcinoma, 5 small cell carcinoma, 1 adenocarcinoma and 1 adenosquamous carcinoma. Pneumothorax developed in 2 patients(14%) and was managed by chest tube drainage. Mild hemoptysis was observed in 2. CONCLUSION: Transthoracic fine needle aspiration biopsy using oblique approach under biplane fluoroscopic guidance is a relatively safe and sensitive method for the histologic diagnosis of subcarinal lesion.

BACKGROUNDS: With the recent elucidation of genetic basis of Rh blood group, it is now available the molecular genotyping methods for Rh blood typing. These can be used when serological typing is difficult. This study was conducted to investigate the usefulness of Rh genotyping method for Koreans. METHODS: Genotyping for Rh C/c and E/e was performed in peripheral blood DNA samples from 34 blood donors by polymerase chain reaction using sequence-specific primers (PCR-SSP). The PCR determined genotypes were compared with serologically determined phenotypes. RESULTS: The Rh C/c and E/e genotyping results of 34 blood donors were full concordance with the results of their serologic phenotyping. CONCLUSIONS: Rh genotyping method on the basis of Rh genetic model can be applied to Koreans. This genotyping method would be useful tool in prenatal Rh typing of fetus at risk of hemolytic disease and when serotyping is not available for example massive transfusion.

Forty five patients with inferior vena cava (IVC) thrombosis were studied with the use of ultrasonography (US) and computed tomography (CT). Thirty seven cases were cased by tumor extension and the primary neoplasms were hepatocellular Ca. (26cases), renal cell Ca. (6 cases), Wilms' tumor (1 case), IVC leiomyosarcoma (1 case) and retroperitoneal metastatic tumor (3 cases). Non-tumor thrombus were 8 cases which included 5 cases of Budd-Chiari syndrome and 3 cases of thrombophlebitis. US and CT both were good for the diagnosis of IVC thrombosis. Cranial extension was better demonstrated by US whereas CT yielded better delineation of the lower extension. Even though, differentiation of tumor non-tumor thrombi by the echogenecity and density of the thrombus was not possible, the finkdings of adjacent tumor mass, complete obstructive thrombus within dilated lumen with bulging wall, and nontapered acute margin of thrombus made the possibility of tumor thrombus more likely.

OBJECTIVE: The purpose of this study was to investigate the incidence of apoptosis and expression of bcl-2 in the placenta of normal pregnancy, Pregnancy Induced Hypertension, and Intrauterine Growth Restriction. METHODS: Placenta samples were collected from 15 cases of normal full-term pregnancies, 15 cases of second trimester pregnancies, 17 cases of Pregnancy Induced Hypertension, and 13 cases of Intrauterine Growth Restriction. Hematoxylin and eosin staining and TUNEL (terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate marker nick end-labeling) staining were used to quantify the incidence of apoptosis and the electron microscopy was used to confirm it. Expression of bcl-2 was confirmed by using immunohistochemical stain in relation to apoptosis. RESULTS: 1. In TUNEL staining, quantification of apoptosis was 1.05 in 2nd trimester (n=15), 3.65 in pregnancy induced hypertensive pregnancy (n=17), 2.92 in intrauterine growth restrictive pregnancy (n=13) and 1.93 in normal full-term pregnancy (n=15). The incidence of apoptosis was significantly higher in placental tissues from full-term pregnancies than second trimester pregnancies (p<0.05, t test), and higher in pregnancy induced hypertensive pregnancy and in intrauterine growth restrictive pregnancy than in normal full-term pregnancy (p<0.05, t test). 2. Bcl-2 expression was significantly higher in placental tissues from second trimester pregnancies than full-term pregnancies (p<0.05 t test). But, there was no statistically significant difference between pregnancy induced hypertension and normal full-term pregnancy (p>0.05, t test), and between intrauterine growth restriction and normal full-term pregnancy (p>0.05, Mann-Whitney U test). CONCLUSION: These data suggest that apoptosis increases with gestational age, and in pathophysiologic states such as pregnancy induced hypertension and intrauterine growth restriction, and that bcl-2 expression is lower with gestational age.
