Two cases of pseudoxanthoma elasticum associated with angioid streaks in both eyes were presented and the literatures were reviewed. The affected sisters were 15 and 18 years female among the five siblings. They had pin head sized yellowish maculopapular eruptions on the sides of the neck and axillae, and also visual distubance of the both eyes. They seemed to be autosomal recessive inberitance in their family background. There were no other complications.

Flow cytometry, a useful tool for measuring DNA content and cell differentiation as expressed by cell surface markers, is utilized to measure multiple antigens, especially surface antigen, intracellular oncoprotein, and DNA content, simultaneously. For this simultaneous detection, several methods off ixation and permeabilization have been used with limited values. In this study, 20 ng/ml of lysolecithin in 1% paraformaldehyde solution was utilized for fixation and permeabilization of cultured promyelocytic leukemic cells(HL 60). The cells were first stained with phycoerythrin (PE)-conjugated monoclonal antibody to the cell surface My 7 antigen and then were fixed and permeabilized with 20 ng/ml of lysolecithin in 1% partormaldehyde solution. After incubation, the fixed and permeabilized cells were stained with monoclonal antibody to intracellular c-myc antigen, which were followed by fluorescein isothiocyanate (FITC)-conjugated secondary antibody. The c-myc stained cells were finally stained for DNA content with 7-amino-actinomycin D(7-AAD). This procedure permits excellent staining for intracellular oncoproteins and preservation of surface antigens with relatively low cofficients of variation (CV) for the G0G1 peak of the DNA histograms and suggests that the sequential staining procedure of surface antigen, intracellular antigen, and DNA content will be extended for the study of correlations with cellular differentiation, expression of oncoproteins, and cell cycle analysis in the cells which are obtained from human malignant diseases using a 488 nm single laser flow cytometry.

PURPOSE: The target volume for the three field technique in breast cancer include the breast tangential and supraclavicular areas. The techniques rotating the gantry and couch angles, to match these two areas, will geometrically produce mismatching of the posterior edge between the medial and lateral tangential beams. This mismatch was confirmed by film dosimetry and three-dimensional computer planning. The correction methods of this mismatching were studied in this article. MATERIALS AND METHODS: After the supraclavicular field was simulated using a half beam block and the medial and lateral tangential fields, by the rotation of the couch and gantry, we compared the following two methods to correct the mismatch. The first method was the rotation of collimator until a line drawn on the posterior edge of tangential beams before the rotation of couch aligned the line drawn on the posterior edge after the rotation. The second method was the rotation of collimator according to the formula developed by the author as follows; Co=2sin(-1){sin angle x sin (C/2)} (Co: collimator angle, angle: angle between tangential beam and table, C: couch angle) RESULTS: The film dosimetry showed the mismatching of posterior edges of the medial and lateral tangential fields prior to the rotation of collimator, while the posterior edges matched well after the rotation of collimator according to the formula. The three-dimensional computer plan also showed that the posterior edges matched well after the rotation of collimator accordingly. The DVH of the ipsilateral lung with the proper rotation of collimator angle was better than that without the rotation of collimator angle. CONCLUSION: The mismatching of the posterior edges of the medial and lateral tangential fields can be recognized on the three field technique in breast irradiation when the gantry and couch are simultaneously rotated and can be corrected with the proper rotation of the collimator angle. The radiation dose to the ipsilateral lung could be lowered with this technique.

Floating thrombi in the aortic arch are very rare, and often go under-diagnosed. Herein, a case of an 8-cm long thrombus in the aortic arch is reported. It was a floating, highly mobile thrombus attached to the atherosclerotic plaque in the proximal aortic arch. The patient was a 59-year-old woman with a history of hypertension. The thrombus was operatively removed, with a favorable outcome.

BACKGROUND: This study compared the results of 24 hour ambulatory blood pressure monitoring with the clinical blood pressure measurements, and we investigated the relationship of the blood pressure measurement and left ventricular hypertrophy, as determined by routine 12 lead electrocardiography. METHODS: We studied 204 healthy adults with no prior history of heart disease or antihypertensive medication. The clinic blood pressure was measured 3 times and the average was taken. We compared the clinic blood pressure with the daytime blood pressure of the 24 hour ambulatory blood pressure monitoring, and we compared the blood pressure with the sum of the voltage of the S wave on V1 and the R wave on V5. RESULTS: The average of the daytime ambulatory blood pressure of all the patients was 135.33+/-13.73 mmHg for the systolic pressure and 86.55+/-10.14 mmHg for the diastolic pressure. The average of the clinic blood pressure measurement was 140.10+/-17.41 mmHg for the systolic pressure and 88.84+/-10.14 mmHg for the diastolic pressure. The clinic blood pressure averaged higher than the daytime ambulatory blood pressure by 5 mmHg on the systolic pressure and 2 mmHg on the diastolic pressure (p<0.001). The normal ambulatory blood pressure limits were estimated as those that best correlated with 140/90 mmHg at the clinic. The estimated value was 135/87 mmHg for the daytime ambulatory blood pressure (p+/-0.001). The incidence of white coat hypertension was 10.8%. The sum of the voltage on electrocardiography showed a positive linear relationship with all the blood pressure measurements. The daytime systolic blood pressure showed the strongest correlation with the 24 hour ambulatory blood pressure monitoring (r=0.283, p+/-0.001). CONCLUSIONS: We found a linear relation and we analyzed the differences between the clinical and 24 hour ambulatory blood pressure. A daytime ambulatory blood pressure value of 135/87 mmHg was a suitable upper normal limit for the corresponding cutoff value of the clinic blood pressure. Left ventricular hypertrophy showed the strongest relationship with the daytime systolic blood pressure among the results of the 24 hour ambulatory blood pressure monitoring.

Background: HLA-DQ typing in deceased donors is not mandatory in Korea. Therefore, when patients develop DQ antibodies after kidney transplantation (KT) from deceased donor, it is impossible to determine whether they are donor-specific antibodies (DSA). We developed DQ prediction programs for the HLA gene and evaluated their clinical utility. Methods: Two HLA-DQ prediction programs were developed: one based on Lewontin’s linkage disequilibrium (LD) and haplotype frequency and the other on an artificial neural network (ANN). Low-resolution HLA-A, -B, -DR, and -DQ typing data of 5,603 Korean patients were analyzed in terms of haplotype frequency and used to develop an ANN DQ prediction program. Predicted DQ (pDQ) genotype accuracy was analyzed using the typed DQ data of 403 patients. pDQ DSA agreement, sensitivity, specificity, and false-negative rate was evaluated using 1,970 single-antigen bead assays performed on 885 KT recipients. The clinical significance of DQ and pDQ DSA was evaluated in 411 KT recipients. Results: pDQ genotype accuracies were 75.4% (LD algorithm) and 75.7% (ANN). When the second most likely pDQ (LD algorithm) was also considered, the genotype accuracy increased to 92.6%. pDQ DSA (LD algorithm) agreement, sensitivity, specificity, and falsenegative rate were 97.5%, 97.3%, 98.6%, and 2.4%, respectively. The antibody-mediated rejection treatment frequency was significantly higher in DQ or pDQ DSA-positive patients than in DQ or pDQ DSA-negative patients (P < 0.001). Conclusions Our DQ prediction programs showed good accuracy and could aid DQ DSA detection in patients who had undergone deceased donor KT without donor HLA-DQ typing.

Quadricuspid aortic valves (QAVs) is a rare congenital malformation. We report two cases of QAV associated with aortic regurgitation. The one is incidentally diagnosed and uncomplicated, and the other is symptomatic and associated with infective endocarditis. In most cases, QAVs are associated with valve regurgitation, with a concurrent stenosis in some patients, while only a small number of QAVs are functionally normal. Once the diagnosis has been made, echocardiographic follow-up is recommended, because of progression to severe valve regurgitation and the risk of infective endocarditis.

48-year-old woman was admitted to emergency room due to left flank pain. It was diagnosed with left ureteral stone and underwent extracorporeal shock wave lithotripsy (ESWL). However, 12 hours later, the patient complained acute upper abdominal pain with pulmonary edema and low blood pressure. A diagnosis of moderate acute pancreatitis with local complication was considered and we decided conservative therapy including fluid resuscitation, inotropics and antibiotics. It was suggested that ESWL was responsible for the acute pancreatitis. The patient gradually recovered and was discharged on 13th day of admission. ESWL is considered the standard treatment for urolithiasis. Although, it has proved to be safe and effective, serious complications have been reported in 1% of patients, including acute pancreatitis, perirenal hematoma, urosepsis, venous thrombosis, biliary obstruction, bowel perforation, lung injury, and cardiac arrhythmia. Although the possibility of post-ESWL acute pancreatitis is extremely low, physicians should take care of this complication.

We investigated the expression of MAGE-1, -2, and -3 genes in tissues of 51 gastric carcinomas from Korean patients and in 11 gastric cancer cell lines established in Korea using reverse transcriptase-polymerase chain reaction along with immunohistochemical analyses and DNA sequencing. Among the 51 gastric carcinomas, MAGE-1, -2, and -3 genes were expressed in 16 (31%), 22 (43%), and 17 (33%), respectively, and 31 (60%) expressed at least one of the three genes. In contrast, none of the three MAGE genes were expressed in normal sites of gastric tissue from each cancer patient. Out of 11 gastric cancer cell lines, MAGE-1, -2, and -3 genes were expressed in two (18%), five (46%), and four (36%), respectively. According to the clinicopathological analysis, the expression of any of the three MAGE genes was not significantly correlated with several clinicopathological factors except histologic types (p= 0.067). Immunohistochemical analyses identified positive staining with monoclonal antibodies 77B and 57B specifically against MAGE-1 and -3 proteins, respectively, in nuclei and cytoplasms of cells in mRNA-positive tumor tissue. These findings suggest the possibility as a target for tumor-specific immunotherapy for Korean patients.

BACKGROUND: Tranilast is an anti-allergic drug that suppresses the release of cytokines. An antioxidant, probucol, prevents endothelial dysfunction and oxidation of low density lipoprotein and also inhibits the secretion of interleukin-1 by macrophages. In several studies, both the tranilast and probucol with multivitamins have been shown to decrease the frequency of angiographic restenosis after PCI. METHODS: We analyzed clinical events and restenosis at 6 months following percutaneous coronary angioplasty in 93 patients with 113 coronary arterial lesions after coronary stenting at Soonchunhyang University Hospital between Jan 2001 and Apr 2003. The patients were assigned to following three groups: 39 patients who didn't receive tranilast and antioxidants (control group, M 29, F 10, 61 +/- 10 years) ; 25 patients who received probucol (500 mg), vitamin C (1,000 mg), vitamin E (400 mg) (antioxidant group, M 19, F 6, 62 +/- 10 years) ; 29 patients who received tranilast (400 mg) (Tranilast group, M 18, F 11, 59 +/- 9 years). RESULTS: The restenosis per lesion between three groups was not different significantly (control group, 32.7%; antioxidant group, 26.7%; Tranilast group, 20.6%). At follow-up, minimal luminal diameter (MLD) was not different significantly between three groups (control group, 1.8 +/- 1.07 mm; antioxidant group, 2.1 +/- 1.18 mm; Tranilast group, 2.1 +/- 0.94 mm). Target lesion revascularization was lower in Tranilast group (3.4%) as compared with control group (25.6%) and antioxidant group (16%, p<0.05). CONCLUSION: Neither probucol combined with vitamin C and E nor tranilast did not improve significantly the angiographic restenosis rate. But tranilast had reduced the target lesion revascularization rate as compared with control group and antioxidant group.
