We expierienced five cases of bilateral inferior vena cava for recent one year. We evaluated the CT findings of the cases and of dilated veins located in the left retroperitoneum (seven left gonadal, seven inferior mesenteric, and two left ascending lumber veins)in the viewpoints of the size, location and relation with the surrounding structures. Bilateral inferior vena cava (IVC) may be asymmetric and the left IYC may be smaller than other retroperitoneal veins with a round contour. The left lYC was located anterior to the spinal body and corresponded with contralateral vena cava in the anteroposterior plane. The gonadal vein was located anterior or anterolateral side of the psoas and always crossed the ureter. Most of the inferior mesenteric vein showed similar location to the opposite site of the vena cava in the anterolateral side of the psoas muscle, medial to the left ureter without crossing. The left ascending lumbar vein was similarly located to the left vena cava but dilated in a short segment. It is required to trace the vessel upward and downward and observe its continuity for correct differentiation. If it is impossible, some differential points suggested in the results of our study will be helpful for distinguishing them.

We present a case of angiographically-confirmed transverse and sigmoid sinus thrombosis, image with MR, in a 20 year old male with a history of otitis media and maxillary sinusitis. T1-weighted image demonstrated an isosignal intensity mass with tubular-shaped low signal intensity in right transverse and sigmoid sinus. The thrombus had high signal intensity on T2-weighted image. The signal intensity of the thrombus on Gd-DTPA enhanced T1-weighted image was unusually high similar to that of transverse sinus. Although dural sinus thrombosis has a non-specific MR signal intensity, findings of MRI in this case may serve as an aid in future evaluation of venous thrombosis.

Antibiotics were reported to be able to alter bacterial surface properties in subinhibitory concentrations (sub-MICs). The effects of sub-MICs of certain antibiotics on a bacterial surface property such as hemagglutination, as well as on the cell morphology were studied using Streptococcus gordonii and Staphylococcus aureus. The effect of sub-M1Cs of antibiotics on the binding of these bacteria to immobilized fibrinogen were also investigated. The MICs of antibiotics were determined by culturing S. gordonii and S. aureus in media supplemented with serially diluted drug solutions, and one-half the MIC was used as the sub-MIC of the drugs, unless stated otherwise. Sub-MICs of antibiotics did not affect bacterial agglutination of erythrocytes. Microscopic observation of S. gordonii grown at sub-MIC concentration of 0.02 ug/ml of amoxicillin revealed cell enlargement of 1.6 times those grown without the drug. When grown in the sub-MIC amount of 0.08 ug/ml of cefazolin, most S. gordonii cells were enlarged and elongated into rod-shape, resulting in 3 times the size of the cells grown without the antibiotic. The data from the fibrinogen-binding experiments showed that the binding of S. gordonii to immobilized fibrinogen was increased with all the B-lactam drugs tested; the binding of S. aureus to immobilized fibrinogen, on the other hand, was decreased with the same drugs. The results show that low concentrations of certain B-lactam antibiotics are able to cause alterations in cellular morphology of S. gordonii and affect the binding of S. gordonii and S. aureus to immobilized fibrinogen.

The association of colonic atresia in patients with Down syndrome is a rare anomaly. The incidence of congenital atresia of the gastrointestinal tract has been estimated to be about one in 1500 births. Colonic atresia is rarer still, and is throut to comprise about 5% to 10% of this group. This intestinal atresia occurs in about 30% to 50% of patient with Down syndrome. We experienced a case of Down syndrome associated with colonic atresia in a 1 day old male. His initial chief complaints at the admission were severe abdominal distension and Down appearance. Diagnosis was confirmed by chromosomal study and operative laparotomy with end-to-end ileodescending colostomy. We report the case with brief review of related literatures.

OBJECTIVE: Peripartum emergency cesarean hysterectomy of 28 cases at our hospital for 10years were reviewed that the clinical indication, history, and annual incidence change. METHODS: A retrospective descriptive analysis from January, 1988 to December, 1997 was carried out. RESULTS: There were 28 cases of emergency cesarean hysterectomy identified during this period among total 24, 689 deliveries. The annual incidence of emergency cesarean hysterectomy was significantly declined statistically(p<0.005). Cesarean hysterectomy was performed in 20 of 6, 671 cesarean section(0.30%) and in 8 of 18, 018 vaginal deliveries(0.04%), so more frequently after cesarean section than vaginal delivery. The cesarean hysterectomy rate was more frequent in multiparous women(0, 22%) than in nulliparous women(0, 02%). The most common indication of cesarean hysterectomy was 13 cases of uterine atony(46%), followed by 5 cases uterine rupture(18%), 5 cases of placenta previa with placenta accreta(18%), 3 cases of placenta previa(11%), 2 cases of uterine myoma(7%). No significant difference in length of operating time, amount of blood loss and operative complications were found between total abdominal hysterectomy and subtotal hysterectomy. The all patient who had cesarean hysterectomy recieved from 1200ml to 15840ml of blood transfusion with a mean of 3673ml. In aspect of fetal outcome, 3 cases of FDIU(Fetal death in utero) in uterine rupture and 1 case of stillbirth in preterm were found. The maternal complications were wound disruption, DIC, wound hematoma, ureter injury, vaginal stump bleeding, UTI(Urinary tract infection) and retroperitoneal bleeding, CONCLUSION: We conclude that the incidence of emergency cesarean hysterectomy declined with prediction of antenatal risk factor, preparing of sufficient fresh blood, prophylactic antibiotics, vigorous uterotonics and close observation after delivery.

After aseptic or septic meningitis, some neurologic complications such as convulsions, delirium, rigidity, cerebral infarctions and cerebral hemorrhage can be developed. The cerebral infarction after meningitis is caused by arterial or venous occlusions. Involvement of small perforating arteries leads to ganglionic infarcts while severe sapsm of major vessels may lead to massive infarctions in the distribution of middle and/or anterior cerebral arteries. Cortical venous and/or dural thrombosis (especially in the superior sagittal sinus) produces typical features, including multiple areas of white matter hemorrhagic infarction. These neurologic complications are common in bacterial meningitis and very rare in aseptic meningitis. We experienced a case of cerebral infarction in MCA/ACA territory and subdural hemorrhage in occipital lobe after aseptic meningitis in 10 month-old-boy. We report a case with a brief review of related literature.
