PURPOSE: To evaluate tlne significance of vaginal air seen on CT scan in preoperative staging of uterine cervical carcinoma. METHODS AND MATERIALS: A comparison was made between CT findings of vaginal air and true vaginal involvement status in 85 patients with uterine cervical carcinoma. CT findings were analyzed in terms of the presence or absence of vaginal air, number of CT slices in which vaginal air was seen, shape of vaginal air, and relation of vaginal airto cervical mass. RESULTS: Vaginal air was present in 35 patients and was absent in 50. Although the mere presence of vaginal air or multiplicity of CT slices showing vaginal air did not signify the presence of vaginal involvement, vaginal air with irregular margin or vaginal air adjacent to uterine cervical mass was suggestive of vaginal involvement. CONCELUSION: These observation of vaginal air in interpreting CT may be helpful in the preoperative staging of uterine cervical carcinoma.

BLAST, a basic bioinformatics tool for searching local sequence similarity, has been one of the most widely used bioinformatics programs since its introduction in 1990. Users generally use the web-based NCBI-BLAST program for BLAST analysis. However, users with large sequence data are often faced with a problem of upload size limitation while using the web-based BLAST program. This proves inconvenient as scientists often want to run BLAST on their own data, such as transcriptome or whole genome sequences. To overcome this issue, we developed NBLAST, a graphical user interface-based BLAST program that employs a two-way system, allowing the use of input sequences either as “query” or “target” in the BLAST analysis. NBLAST is also equipped with a dot plot viewer, thus allowing researchers to create custom database for BLAST and run a dot plot similarity analysis within a single program. It is available to access to the NBLAST with http:/bitglobal.comblast.

One hundred and twenty seven patients with uterine cervical carcinoma underwent computed tomography(CT) and magnetic resonance(MR) imaging, followed by surgical exploration. MR imaging was superior to CT in visualization of the tumor, for parametrial evaluation, and for tumor staging. MR imaging had an accuracy of 74% in the assessment of thickness of cervical stromal invasion. The accuracy rates for parametrial evaluation were 78% for CT and 88% for MR imaging. The overall accuracy rates for tumor staging were 68% for CT and 80% for MR imaging. The accuracy rates for pelvic lymph node evaluation were 82% for CT and 85% for MR imaging. Our findings suggest that MR imaging is supperior to CT in preoperative staging of uterine cervical carcinoma.

Since coronary arteriovenous fistula(CAVF) was first reported by Krause in 1865, more than 400 cases have been reported. It is relatively rare disease and originates more commonly in the right than in the left coronary artery. We report a case of CAVF between right coronary artery and right ventricular inflow tract with significant left to right shunt in a 34-year old female who was admitted for the cardiomegaly on routine chest X-Ray. It was detected by transthoracic and transesophageal echocardiography, and confirmed by cardiac catheterization and coronary angiography. The opening of the fistula draining into the right ventricle was obliterated with sutures. There was no significant shunt in postoperative cardiac catheterization and coronary angiography.

PURPOSE: Cervical neoplasias are known to be preventable. But the outcome of our efforts for early detection in Korea is disappointing. This study was undertaken to determine the level of screening participation in Korean women with cervical cancer and how the early detection of cervical cancer might be improved. MATERIALS AND METHODS: Two hundred and forty-nine women with cervical cancer diag- nosed and treated at Seoul National University Hospital from September 1996 to February 1998 were subjected to this study. Self-reported cervical cancer screening histories, med- ical records obtainable were reviewed and analysed. RESULTS: One hundred forty-seven women (147/249; 59.0%) hadn't got through the screen- ing at proper intervals. Ninety-nine women (39.9%) had never been screened and remain- ing 48 (19.3%) hadn't had their last Pap test 3 years before their diagnosis of nvasive cancer. Of the 150 women (60.1%) who had ever had a Pap test, only 47 (18.9%) had had annual Pap test during recent 5 years and 55 (22.1%) had had routine Pap test with interval between 1-3 years. Among 102 women who had at least one Pap test during recent 3 year, 73 (71.6%) had had a normal Pap report within three years of diagnosis, including 36 (35.3%) whose last normal Pap report was within a year of diagnosis. This results suggest the possibilities of smear-taking and/or reading errors. Women who had had routine Pap with interval less than 3 years had significantfy less chance of advanced tumor (FIGO stage Ib < ) than unscreened population. There was a statistically significant trend for the more younger and educated groups to be participated at the screening program with more shortened interval. All the other factors had failed to show significant correlation with adequacy or regularity of screening interval. CONCLUSIONS: Despite widespread chance of opportunistic cervical cancer screening, non-participants form the main reason for the failure of cervical cancer screening in Korea. So, far much efforts should be aimed at participating more women in cervical cytologic screening program, especially in the old-aged and less-educated groups.
