Polyamines are closely related to cell growth and differentiation and increased levels of urine polyamines (UPs) has been reported in various human cancers. However, there were few reports on changes of UPs in patients with cervical carcinoma. We investigated the clinical utility of UPs as well as serum squamous cell carcinoma (SCC) antigen in cervical carcinoma. The association of pretreatment SCC antigen and UPs with clinicopathologic parameters was assessed in 478 patients with cervical carcinoma. SCC antigen was measured by radioimmunoassay and UPs by enzymatic assay method. The prognostic significance of pretreatment SCC antigen and UPs, and the relationship between pretreatment and posttreatment SCC antigen and UPs according to treatment modalities were analyzed. There was a trend of increased level of UPs with cancer progression, whereas significant difference of SCC antigen value was found with cancer progression. Among various clinicopathologic parameters, tumor size and macroscopic lymph node metastasis were associated with pretreatment SCC antigen and UPs level as well. Increased pretreatment SCC antigen level (>2.0ng/ml) and UPs level (>45 micromol/g creatinine) had significant impact on survival. Multivariate analysis revealed that pretreatment SCC antigen, lymph node metastasis and tumor size were independent prognostic factors on survival in the same stage patients. SCC antigen levels decreased after radiotherapy and neoadjuvant chemotherapy. In patients treated by radiation, response status was associated with postradiation SCC antigen, which showed a good correlation with survivals. UPs positivity and SCC antigen positivity in 42 recurrent cervical cancers were 64.7% and 57.9%, respectively. Pretreatment SCC antigen, combination of SCC antigen and UPs, tumor size, macroscopic lymph node metastasis and invasion depth were correlated with recurrent or residual cervical carcinoma. In conclusion, UPs together with SCC antigen may be used to assess the extent of disease status and to define the prognosis in cervical carcinoma.

Coronary artery bypass grafting (CABG) without extracorporeal circulation (ECC) is now an accepted technique of myocardial revascularization in selective cases of coronary arterial occlusive disease. We experienced a case of CABG without ECC in a 20 year old female patient with complete occlusion of the right coronary artery. Anesthesia was induced and maintained with fentanyl, midazolam and isoflurane. Nitroglycerine and dopamine were given to stabilize the hemodynamics during intra- and post-operative periods. And esmolol was administered with a loading dose of 30 mg over 1 min, followed by a continuous infusion of 50~100 g/kg/min to maintain the heart rate (50~60 beats/min) and systolic blood pressure (60~80 mmHg) during distal anastomosis. The patient was recovered uneventfully and discharged on the 8th postoperative day.

From the Department of Dermatology, College of Medicine, The Catholic University of Korea, Kangnam St. Mary's Hospital, 505, Banpo-Dong, Seocho-Gu, 137-040, Seoul, Korea, Gastrointestinal stromal tumors are usually late manifestations of neurofibromatosis (von Recklinghausen's disease) and most become clinically apparent in middle-aged patients as multiple benign tumors. To our review of the literature, solitary malignant stromal tumor of gastrointestinal tract is exceptionally rare in von Recklinghausen's disease. We herein present a case of solitary jejunal stromal tumor in a 50-year-old woman with NF1, which histopathologically showed a malignant change and combined smooth muscle-neural type.

Anterior or lateral neck mass that appears on straining should be differentiated from laryngocele, jugular phlebectasia and superior mediastinal cysts or masses. The most common cause of aneck masses which that appears on straining is alaryngocele. The jugular phlebectasia may present itself in a similar manner, although it occurs rarely. The cause of the jugular phlebectasia is unclear. The diagnosis is made on a clinical basis and confirmed by the less invasive radiological technique. No treatment is indicated because of its self-limiting, benign condition. However, the surgical removal is needed for cosmetic purposes by a unilateral excision of the jugular vein. We experienced two cases of jugular phlebectasia, one anterior and the other internal. One case of The anterior jugular phlebectasia was successfully treated by surgical excision, and the other case of internal jugular phlebectasia was treated conservatively.

PURPOSE: To elucidate high-resolution CT(HRCT) findings and their pathologic basis in pulmonary oil embolism induced by LipiodoI-Adriamycin emulsion. MATERIALS AND METHODS: Pulmonary oil embolism was induced by infusing LipiodoI-Adriamycin emulsion through a peripheral vein in twelve Yorkshire pigs. Serial HRCT scans were performed on 2rid, 4th, 7th, 14th, and 28th day after the procedure. The pigs were sacrificed immediately after HRCT and histologic specimens were prepared in the same plane and level with HRCT. RESULTS: The basic pathology was reversible hemorrhagic edema of the lung. On HRCT, intraalveolar hemorrhage and edema in the acute stage manifested as ground-glass opacity or air-space consolidation of the whole secondary Iobule. The lesions were predominantly distributed over the dependent posterior lung fields because the specific gravity of Lipiodol is 1.28. Interlobular septal thickening due to edematous fluid collection was also associated. With the elapse of time, the extent and severity of the acute lesions resolved and, sometimes, changed into small nodular opacities. Pulmonary opacity was most severe on the post-embolization 2nd day and completely resolved within 2 weeks. CONCLUSION: Pulmonary embolization of LipiodoI-Adriamycin emulsion causes reversible hemorrhagic edema of the lung and Lipiodol toxicity seems to play a major role. HRCT findings of pulmonary oil embolism are quite different from those of pneumonia and pulmonary metastasis, which suggests the possibility of clincal application.

PURPOSE: Authors investigated the associated findings and their value in the diagnosis of anterior cruciate ligament(ACL) injury in MR image. MATERIAL AND METHODS: The knee MR images of 47 patients with ACL injury(complete; 24, partial; 23) and 61 patients with normal ACL confirmed by the knee arthroscopy or operation were reviewed retrospectively. The degree of anterior translocation of tibia and the degree of posterior cruciate ligament(PCL) buckling were evaluated. The prevalence and pattern of associated adjacent bone, ligament and meniscus injuries were studied. RESULTS: The means( +/- 2standard errors) of anterior translocation were different significantly in statistical analysis(p<0.001, student t-test) between injury group(7.51 +/- 1.16mm) and normal group(-0.56 +/- 0.92mm). In the level of 5mm of anterior translocation for the criteria of ACL injury, the sensitivity, specificity, accuracy were 78.7%, 89.5%, 84.3% for each. The means of PCL buckling ratio were also different statistically b. etween injury group(0.23 +/- 0.02) and normal group(0.17 +/- 0.01)(p<0.001). In the level of 0.20 for diagnostic criteria of ACL injury, the sensitivity, specificity, accuracy were 71.4%, 83.6%, 78.4% for each. Thirty one medial meniscus tear(66%), thirteen lateral meniscus tear(28%), ten medial collateral ligament injury(28%), one PCL injury (2%) were associated with ACL injury. The twenty nine bone marrow changes were found in twenty patients {43%) which included acutely injured seven patients. In acute cases, the bone marrow changes were depicted as diffuse or focal high signal intensity lesions in lateral femoral or tibial condyles in contrast to the changes in chronic cases depicted as focal low signal intensity lesions in variable location. Lateral femoral condylar notch depression were found in nine patients(19%) and avulsion fractures of anterior tibial spine in four patients(9%). CONCLUSION: The associated findings with ACL injury (anterior translocation, buckling of PCL, associated bone, ligament and meniscus injuries) are considered to be helpful in the diagnosis of ACL injury on Knee MR images, when the findings of anterior cruciate ligament itself are not confirmative.

In portal hypertension, hepatopetal flow is rerouted away from the liver through collateral pathways to low pressure systemic vessels. Information about collateral pathways is relevant, especially when interventional procedure or surgery is contemplated, because inadvertent disruption of these veins can cause significant bleeding. Dynamic CT and spiral CT with a bolus injection of contrast material have to a significant extent recently replaced angiography. The porto-systemic collateral pathways have, however, been classified and described according to location or frequency in a majority of previous reports. This essay illustrates variable porto-systemic collateral blood flow pathways, with CT and angiography correlation.

This study aims to examine the effect of methylphenidate, which is the most extensively prescribed medicine treating children with Attention Deficit Hyperactivity Disorder (ADHD), on the children's neuropsychiatric functions by comparing the symptomatic differences before and after its medication. MEHTODS: The subjects of this study were 48 children who corresponded to the diagnostic criteria for ADHD of DSM-IV, did not have any problem in vision or hearing, did not have neurologic disorder such as epilepsy and brain damage, and did not have other long term medication. To evaluate the effects of behavioral response and medication, after stopping medication over a week we handed out questionnaires to the parents and conducted CPT to the subjects. A dose of 0.3-0.7 mg/kg (bid or tid) was medicated at 8AM and 1PM everyday. After 4 weeks of medication, the same tests were conducted. RESULTS: Average age of the subjects was 8.88+/-1.55. There were 44 boys (91.7%) and 4 girls (8.3%). Mean intelligence was 96.60+/-18.12 and mental processing was 102.90+/-16.51. On ADDES-HV, after medication attention, impulsivity and hyperactivity were significantly improved (p<0.05). On AcTeRS, after medication attention, impulsivity and social skill were significantly improved (p<0.05). On CAPs, after medication inattention and hyperactivity were significantly improved (p<0.05). On SNAP, after medication inattention impulsivity and hyperactivity were significantly improved (p<0.05). On the academic performance rating scale, after medication total score, learning ability, impulse control and social withdrawal were significantly improved (p<0.05). On performing CPT, after medication commissions error, hit reaction time standard error, variability of standard error and attentiveness were significantly improved (p<0.05). CONCLUSIONS: With these results, we recognized methy-lphenidate is more effective in children's impulsivity and hyperactivity than attention, contrary to the clinical observation.
