BACKGROUND: To compare the diagnostic usefulness of dobutamine stress echocardiography(DSE) and 99mTc-methoxyisobutyl isonitrile SPECT (MIBI SPECT), two studies were performed simultaneously. METHOD: Fifty-six consecutive patients undergoing coronary angiogram and MIBI SPECT for clinical indications without clincal evidence of myocardial infarction were studied prospectively. During the DSE, MIBI was injected at peak stress, and post-stress images of MIBI SPECT were required on hour later. Both echocardiographic and MIBI SPECT images were visually analysed in a blind fashion. RESULTS: On the basis of coronary angiographic findings, the sensitivites of the DSE and MIBI SPECT (n=36) were 89% and 86%, respectively. The specificities of those (n=20) were 90% and 85%, respectively. Among 33 patients without resting perfusion defect on MIBI SPECT, resting regional wall motion abnormalities on DSE were found in only one patient, whereas, resting perfusion defect on MIBI SPECT were found in 9 patients among 41 patients without resting regional wall motion abnormalities on DSE. Among 17 patients who had resting perfusion defects with partial reversibility on MIBI SPECT, resting wall motion abnormalities were present in 11 patients and five of them showed improvement in the regional wall motion during low dose dobutamine infusion. CONCLUSION: Both dobutamine stress echocardiography and MIBI SPECT are useful methods in the detection of the coronary artery disease, however, MIBI SPECT seems to overestimate the regional ischemic myocardium with contractile reserve that can hardly be evaluated with MIBI SPECT.

Anti-E and anti-c is one of the clinical significant irregular antibodies developing a delayed hemolytic transfusion reaction and hemolytic disease of the newborn. Since anti-c occurs frequently with anti-E in immunized people whosoe cells are E-and c-, it has been recommended to select blood of the patient's own R1 phenotype for transfusion, even when the presence of anti-c cannot be demonstrated in his/her serum. To determine the utility of this approach, we reviewed the blood bank laboratory records of patients identified anti-E and anti-c in his/her serum in Severance hospital over a 12 year period (1985-1996). During the 12-year period of study, 53 patients were identified with anti-E and/or anti-c; 30(56.6%) patients had anti-E alone, 6(11.3%) had anti-c, and 17(32.1%) had both. Thirty eight of forty two patients whose Rh-hr phenotypes were tested were R1R1. Of these 38 R1R1 patients, 16 patients (42.1%) presented with anti-c concomitant with anti-E. Ouru study showed that the incidence of antni-c in R1R1 patients with anti-E is similar to that of studies reported in Caucasian groups. We highly suggest the transfusion protocol of prophylactic use of c negative blood for R1R1 patients with anti-E. Furthermore, because anti-c may be present in concentrations too low to be detected, the enzyme technique is recommended in parallel with standard serologic methods for the identification of irregular antibodies.

Authors presented the serial changes of brain MRI findings in two cases of cryptococcal meningitis. The MRI findings of the first patient (53-year-old female) consisted of dilated Virchow-Robin spaces, leptomeningeal enhancement, cryptococcomas and hydrocephalus. Dilated Virchow-Robin spaces were noted on the first MR obtained 33 days after symptom onset. The size and number of dilated Virchow-Robin space gradually decreased since 119 days after symptom onset (62 days after treatment). Faint leptomeningeal enhancement was found at cerebellar region on the first MRI, which became more distinct and intense on the day 119, probably due to improper treatment. The leptomeningeal enhancement decreased on the day 156. Mild hydrocephalus was noted on MRI obtained 70 days after symptom onset, which markedly aggravated on the day 119. It decreased after steroid therapy alone. Enhancing crytococcomas of variable size were noted at the right temporal lobe and cerebellum on MRI of the day 119, which decreased in size and number on the day 156. On the day 295 MRI showed nearly disppearance of the dilated Virchow-Robin space, but faint leptomeningeal enhancement, cerebellar crytococcomas and hydrocephalus still remained. The MRI findings of the second patient (36-year-old female) showed the findings similar to those of the first patient. Initial MRI obtained 18 days after symptom onset showed no abnormal findings. Dilated Virchow-robin spaces were noted on the day 36 (13 days after treatment onset), which nearly disappeared on the day 109. Enhancing cryptococcomas in both basal ganglia and cerebral cortex and leptomeningeal enhancement were noted on MRI of the day 136. Both cryptococcomas and leptomeningeal enhancement decreased in size and enhancing degree on the day 157. Hydrocephalus was noted on the day 109.
