OBJECTIVE: The objective of this study is to nfluence of sequential embryo transfers in an invitro fertilization was examined. METHOD: After in vitro fertilization, a maximum of 6 fertilized oocytes was enrolled in this study. At day 3 after an oocytes retrieval, embryos with good quality were transferred (mean 4.9), remaining embryos (mean 2.0/cycle) were cryopreserved at blastocyst stage (Group 1). At day 5 after oocytes collection, second a embryos had reached the blastocyst stage (Group 2) using P1 supplemented with 10 SSS and 30% Follicular fluid. No statistical difference in the pregnancy rate could be seen between the group without a second embryo transfer (n=21; 28.6%) and the group with a second transfer (n=52; 28.8%). RESULTS: The incidence of multiple pregnancy rate per embryo transfer was not statistically different between both group and no high-rank multiple pregnancy (greater than triplete) were observed (o.9%, 15.4%, respectively, p=0.74, chi2). Out of 114 cycles (506 embryos) cultured embryos in group 2, 52 cycles (159 embryos, 29.8%) reached the blastocyst stage. CONCLUSION: The second transfer did not have a significant effect on the pregnancy rate. The most important factor for the pregnancy seems to be the quality of the embryos transferred on day 3 following oocyte retrieval. We recommend embryo transfer is performed only one, day 2~3 or D5.

The acardius occurs with an incidence of one in 35,000 births and is presumed to result hom vascular anastomosis between the arterial circulation of the hemodynamically larger ""pump"" twin and that of the recipient ""perfused"" twin. The perfused twin displays severe anomalies, typically referred to as acardia, that are incompatible with life. The pump twin, because of its expanded cardiac demand, may also deveolp cardiac failure, with a mortality risk of 50-70%. We experienced one case of acardiac-acephalus twin gestation diagnosed by antenatal ultrasonography, and presented this.

We analysed the ultrasonographic findings in 46 cases of PID, examined atYyonsei Universtiy Severance Yondong Hospital from June 1983 to Dec. 1984. Among them, 29 cases of PID were well correlated with pathologic findings bysurgery or laparascopy. The results were as follows; 1. The age was ranged from 14 years to 57 years of age andthe majority was between 21 years and 50 years of age. 2. We evaluated the ultrasonographic findings of 46 casesunder the criteria of Swayne's classification. They are 67% in type II, 17% in type III and 4% in type I. Theremained is 11% in normal finding. 3. Among 29 cases pathologically proven,the ultrasonographic findings areclassifed to be 66% in type II, 21% in type III, 3% in type I and the remained is normal. Among type II PIDcases, tubo-ovarian abscess is 32%, pelvic abscess is 26% and pyosalphinx is 16%. The pelvic-peritoneal adhesionis demonstrated in 83% of 6 cases of type II lesion. 4. In 36 cases of PID, uterine mass formation is demonstrated and located unilaterally in 64%, associated fluid collection in 47% and bladder indentation in 36% was noted. The diameter of mass shadow is about 4.4cm of average, ranged between 2-9cm. The echogenecity was mixed in 64%, cysticin 31% and solid in 5% of mass lesion.

PURPOSE: To evaluate the accuracy of CT using water as an oral contrast material in a prone position in determining the depth of tumor invasion in gastric cancer patients. MATERIALS AND METHODS: Thirty three patients(19 male, 14 female) with surgically confirmed gastric cancer were studied. We performed CT in a prone position after ingestion of 1 liter of pure water. CT findings were classified into 4 groups by the morphologic appearances of infiltrates in the perigastric fat plane :normal perigastric fat(SO), fine mottled densities(S1), irregular aggregated or linear densities(S2) and direct extension and invasion of tumor into contiguous structures(S3). Also we prospectively compared the CT staging with pathologic T staging according to the TNM systems. RESULTS: The overall accuracy of CT staging in determining the pathologic T factor was 69.6%. As we regarded T1 and T2 lesions as one group on CT, the accuracy of CT staging was increased to 80.2% because of a limitation of CT for distinguishing T1 from T2 lesions. CONCLUSION: Prone position CT using water as an oral contrast agent is quite accurate in determining the T staging of gastric carcinoma.

Abdominal cystic lymphangioma is a rare congenital malformation of lymphatics. Prognosis is excellent with exact diagnosis and complete surgical excision. The aughors analysed 10 US scans and 9 CT scans of surgically proven cystic lymphangiom for the last 5 years. US scan showed it as a septated cystic mass and 2 cases showed fluid-fluid level. CT scan showed a huge unilocular or multilocular density mass with uniformly thickened septae. A huge unilocular or multilocular cystic mass with uniformly thickened septae could suggest cystic lymphangioma would be differentiated from the other cystic masse.

PURPOSE: To compare the detectability and conspicuity of focal hepatic lesions among conventional spin echo techniqueniques and fast scanning techniqueniques in MR imaging. MATERIALS AND METHOD: 36 patients (24 men and 12 women, mean age of 54 years) with suspected liver mass on CT scan and US underwent MR imaging at 1.5 T system. Conventional spin echo T1, T2 weighted imaging, T2 weighted fast spin echo, T1 weighted fast multiplanar spoiled gradient recalled(FMPSPGR) imaging and Gd-enhanced FMPSPGR(Gd-FMPSPGR) were performed. 16 cases of hepatocellular carcinoma, 13 cases of hemangioma, 3 cases of metastasis, 3 cases of cholangiocarcinoma, and 1 case of lymphoma were included. Lesion conspicuity and number of detected hepatic masses were compared among the MR sequences. RESULTS: Overall 63 hepatic lesions were detected in 36 patients. Lesion detection' was 63(100%) with Gd-FMPSPGR, 62(98%) with non-enhanced FMPSPGR, 58(92%) with SE T2WI, 56(89%) with SE T1WI and 54 (86%)with FSE. For solid tumors, the contrast to noise ratio was greatest on Gd-FMPSPGR which was significantly higher than any other sequences. For hemangiomas it was greatest on SE T2WI and was significantly higher than SE T1WI. In the qualitative assessment, Gd-FMPSPGR was preferred for both solid mass lesion and hemangioma. FSE was inferior to SE T2WI for lesion detection and conspicuity without statistical significance. CONCLUSIONS: For the evaluation of focal hepatic lesions, breath-hold FMPSPGR with and without contrast enhancement may replace the conventional SE T1WI. Because FSE was inferior to SE T2WI when the later is used with respiratory compensation in some cases, it is difficult to replace the SE T2WI with FSE. But FSE, FMPSPGR and Gd-FMPSPGR images, when combined, may replace SE T1WI and SE T2WI.

Callus is a nonpenetrating circumscribed hyperkeratosis produced by repeated friction or pressure. It occurs on parts subjected to intermittent pressure, particularly on the palms and soles, and particularly over the bony prominences of the joints. In painful callosities of the feet, ill-fitting shoes and orthopedic problems of the foot (bunions, exostoses) are some of the etiological factors to be considered. Gout is a condition of inborn metabolic and/or acquired form of the disease characterized by hyperuricemia, tophaceous deposits of sodium urate and recurrent attacks of arthritis. We present a case of callus caused by tophi. The patient was a 45-year-old man who had complained of a painful, well-demarcated, hyperkeratotic plaque on the heel of the left foot for 18 months. After the tophi beneath overlying whitish thickened skin had been removed, the skin lesion disappeared and to date has not recurred.
