About 20 or more cases of seminal vesicle cyst were reported up to nowadays, but CT findings are not yetdescribed. Seminal visicle cyst is often associated with ipsilateral renal agenesis, and the mechanism ofdevelopment is based on embryogenesis. A 26 year old male was confirmed as seminal vesicle cyst in S.N.U.H. inNov. 1981. CT of the seminal vesicle cyst revealed huge, globular and homogeneous mass with well-circumscribedsmooth margin between urinary bladder and rectum. Adilated tubular structure was also found lateral to the hugecystic mass. The ipsilateral kidney was not found in any level of abdomen from the diaphragmetic dome to thesymphisis pubis.

Purpose: To analyze the causes and to prevent dislocations of the hip joint that occur in patients who underwent revisions of total hip arthroplasties by changing only the polyethylene liners and femoral heads, subsequent to primary total hip arthroplasties. Materials and Methods: We evaluated 28 patients who underwent acetabular component revisions of total hip arthroplasties subsequent to primary total hip arthroplasties. The average age of the patients was 55 years old and all 28 patients had operations through the posterolateral approach. In 17 of the cases, the acetabular cups, polyethylene liners, and femoral heads were changed; in 10 cases, just the polyethylene liners and femoral heads were changed; and in 1 case, only the polyethylene liner was changed. Results: We observed 7 cases of hip dislocations that occurred among a total of 28 cases after revisions of total hip arthroplasties. In all 7 cases, the polyethylene liners and femoral heads were changed, but not the acetabular cups. In additional, in all 7 cases of dislocation, the patients were non-compliant and started weight-bearing prematurely after revisions of the total hip arthroplasties Conclusion: We observed new dislocations in the 7 cases in which the polyethylene liners and femoral heads were changed. The main reasons were inadequate soft tissue tension and hip joint laxity. Therefore, it is necessary to increase the neck length, use elevated rim polyethylene liners, readjust the acetabular cups to their optimal positions, and apply hip abduction braces to patients early after revision of total hip arthroplasties in order to lessen the danger of dislocations.

BACKGROUND: The purpose of the study was to investigate prospectively the relation of lipoprotein(a)[Lp(a)],apoproteins and serum lipid parameters to restenosis after percutaneous transluminal coronary angioplasyt(PTCA). METHODS: One hundred and forty-five patients who received successful PTCA were enrolled and their serum levels of lipids, apoproteins and Lp(a) were measured before PTCA. After 6 months of follow-up, the patients were reevaluated for the development of restenosis by coronary angiography, treadmill test or thallium scan. RESULTS: A total 137 patients could be followed. Restenosis occurred in 71 patients(52%). Clinical parameters(e.g. age, sex, hypertension, diabetes, smoking) and angiographic parameters(e.g. lesion site, type and degree of stenosis) were not significantly different between the group without restenosis and the group with restenosis. Lipid parameters and apoproteins were not associated with restenosis. Lp(a) and Lp(a) phenotype analysis showed no significant difference between the two gruops. CONCLUSION: Serum lipid parameters, apoproteins and Lp(a) concentration are not associated with restenosis after PTCA and cannot be used as predictios of restenosis.

INTRODUCTION: To prevent hemodialysis-related infections, it is important to maintain hemodialysis system without microbial contamination. In May 2003, routine surveillance showed that dialysis water from dialysis port was contaminated with bacteria. To identify the causes of the contamination, we conducted an investigation as follows. METHODS: Patients undergoing dialysis were carefully monitored to see whether evidences of pyrogenic reactions or infections were present. Factors that could have influence on bacterial contamination in hemodialysis systems were thoroughly examined. In addition, microbiologic surveillances were done 7 times in 1 month. RESULTS: Although pyrogenic reactions or bacteremia did not occur, R. pickettii was repeatedly isolated above the Association for the Advancement of Medical Instrumentation (AAMI) standards from almost all dialysis units. Bacterial counts of specimens were higher in the proximal part of the water supply tube than the other parts in all dialysis machines. The colony count of R. pickettii exceeded the maximum level of technical limit in the specimens collected from the dialysis machines in the early morning after intermission of 48 hours. The structure of the supply tube was suspected as the origin of the colonization because stagnant water is a reservoir for bacterial multiplication. After remodeling the structure of the water supply tube, neither R. pickettii nor any other bacteria were isolated. CONCLUSION: Our investigation successfully identified the source of R. pickettii contamination of reverse osmosis water. Appropriate corrective measures for water distribution systems of hemodialysis center could prevent outbreak of dialysis-associated illnesses.

This study was designed to evaluate the potential applicability of magnetic resonance imaging (MRI) for the diagnosis of acute renal vein thrombosis. Renal vein thrombosis was experimentally induced by surgical ligation of the left renal vein in a total of 21 rabbits. MRI was performed with a 0.5 Tesla superconductive magnetic system. Spin echo technique was used with varying TR and TE parameters. Spin echo images of the rabbit kidney were analysed for morphology and signal intensity. T1 and T2 relaxation times of the renal cortex and medulla were calculated from the images. After venous ligation, kidneys became enlarged. Low signal band along the outer medulla in T2 weighted images were characteristically shown from 1 hour to 3 days after ligation, Changes of cortex to medullar contrast (CMC) values were significant (p<0.05) in T1 - and T2- weighted images of the ligated side. T1 and T2 relaxation times were significantly prolonged (p<0.05) on the ligated side, both in the cortex and medulla from 1 hour to 2 weeks after the ligation, while T2 relaxation time on the contralateral side was significantly prolonged both in the cortex and medulla 2 weeks after venous ligation. The most useful MRI criteria for the diagnosis of renal vein thrombosis were enlarged renal size, and the low signal band along the outer medulla of ligated kidney. The relative intensity difference between cortex and medulla (CMC) in T1-and T2-weighted images, and T1 and T2 relaxation times were suggested to be the useful MR parameters for the diagnosis of acute renal vein thrombosis.

Herlyn-Werner-Wunderlich (HWW) syndrome is a rare, congenital genitourinary anomaly involving the Müllerian and Wolffian structures, and is characterized by the triad of uterine didelphys, obstructed hemivagina, and ipsilateral renal agenesis. It usually presents in adolescent girls in whom hematometrocolpos produces a pronounced mass effect and pain on the side of the obstructed hemivagina. Accurate diagnosis and surgical treatment can be delayed for several months or even years. Here, we report a case of a 12-year-old girl who presented to the emergency department with lower abdominal pain and mass that had lasted for 2 weeks. After the confirmation of HWW syndrome with magnetic resonance imaging, hysteroscopic septostomy was carried out as a definitive treatment. When we evaluate adolescent girls with lower abdominal pain and mass, we should consider the possibility of HWW syndrome.

To determine the perinatal mortality and morbidity of fetuses with absent end-diastolic velocities (AEDV) of the umbilical artery in severe pre-eclampsia and eclampsia, the outcome of 5 fetuses with AEDV was compared with that of 35 fetuses with positive end-diastolic velocities (PEDV). The study population comprised 38 cases of severe pre-eclampsia and 2 cases of eclampsia with structurally normal singletons, who had had umbilical artery Doppler velocimetry weekly from admission to delivery. The Doppler velocimetry result was not used for the clinical management. Perinatal death and neonatal morbidity from both groups were further examined in gestational age category to control the influence of preterm births. The incidence of AEDV of the umbilical artery Doppler velocimetry in severe pre-eclampsia and eclampsia was 12.5% (5/40). The AEDV group had a significantly higher incidence than the PEDV group in terms of ceasarean section due to fetal distress (60% : 17%), Apgar score < 7 at 5 minutes (60% : 14%), perinatal death (25% : 0%) and assisted mechanical ventilation (67% : 9%) both at 32-36 weeks. Time intervals from the detection of AEDV to delivery of live neonates varied from the day to 15 days. In conclusion, AEDV in the umbilical artery might be of clinical value in routine surveillance of pregnancies complicated by severe pre-eclampsia and eclampsia, and predict hypoxic fetal condition which needs operative interventions before or during labor and mechanical ventilation after birth.
