PURPOSE: We investigated the role of myocardial perfusion SPECT in prediction of ventricular dilatation and the role of revascularization including thrombolytic therapy and PTCA in prevention of ventricular dilatation after an acute myocardial infarction (AMI). MATERIALS AND METHODS: We performed dipyridamole stress, 4 hour redistribution, and 24 hour reinjection Tl-201 SPECT in 16 patients with AMI two to nine days after attack. Perfusion and wall motion abnormalities were quantified by perfusion index (PI) and wall motion index (WMI). Left ventricular ejection fraction (LVEF), WMI and ventricular volume were measured within 1 week of AMI and after average of 6 months. According to serial changes of left ventricular end-diastolic volume (LVEDV), patients were divided into two groups. We compared WMI, PI and LVEF between the two groups. Relationships among degree of volume, stress-rest PI, WMI, CKMB, Q wave, LVEF and revascularization were analysed using multivariate analysis. RESULTS: Only initial rest perfusion index was significantly different between the two groups (p<0.05). While initial LVEF, stress PI, CKMB, trial of revascularization procedure, presence of Q wave and WMI were not significantly different between the two groups. Eight of 16 patients (50%) showed LV dilatation on follow-up echocardiography. Three of 3 patients (100%) who did not undergo revascualrization procedure documented LV dilatation. And only 5 (38%) of the remaining 13 patients who underwent revascularization revealed LV dilatation. There was no difference in infarct location between the two groups. By multivariate linear regression analysis in patients only undergoing revascularization, rest perfusion index was the only significant factor. CONCLUSION: Myocardial perfusion SPECT performed prior to revascularization was useful in prediction of LV dilatation after an AMI. Rest perfusion index on myocardial perfusion plays as a significant predictor of left ventricular dilatation after AMI. And revascularization appears to be a valuable procedure in alleviating LV dilatation after AMI with or without viable myocardium in a limited number of patients studied retrospectively.

OBJECTIVE: To characterize the clinical features of platinum compounds (cisplatin plus carboplatin) associated hypersensitivity reactions. METHODS: Medical records of 102 patients with gynecologic malignancy who received chemotherapy based on platinum at Center for Uterine Cancer from Jun. 2001 to Nov. 2002 were analyzed. Platinum hypersensitivity reaction was classified as acute and delayed reaction according to the time of onset, also mild and severe reaction according to the severity of symptoms and signs. RESULTS: Among the 102 patients treated with platinum compounds during this period, 20 (20%) developed hypersensitivity reaction. The median number of platinum courses for the first episode was 7 (range 4-9) and it concentrated at 7, 8, 9th cycles. Fourteen patients developed acute reaction and six patients experienced delayed reaction. Ten patients experienced severe symptoms including dyspnea. Acute reaction developed from a few minutes to 30 minutes after the initiation of the platinum infusion. Delayed reaction developed after discharge of patients with mild intensity. CONCLUSION: Platinum hypersensitivity reactions develop in patients who have been extensively pre- treated with these agents. As platinum compounds are increasingly used as neoadjuvant, initial, second-line chemotherapy of ovarian cancer and concurrent chemoradiation, palliative setting of cervical cancer, it can be anticipated that hypersensitivity reactions to these drugs will happen more frequently, at the same time it might be a important issue for clinicians engaged in chemotherapy.

OBJECTIVE: The purpose of this study was to investigate the clinical feasibility of FDG-PET scan in selection of patients with pelvic recurrence of cervical cancer for surgical treatment. METHODS: From Jun. 2001 to Oct. 2002, whole body FDG-PET scan findings were compared with findings of CT, MRI, and pathologic reports in 24 patients with pelvic recurrence of cervical cancer. PET scan was obtained with a GE Advance PET scanner, beginning at 60 minutes after injection of 370-555 MBq (10- 15 mCi) of 18F FDG. Regional scan was also obtained if needed. Uptake exceeding 2.5 SUV was determined as a positive finding. RESULTS: Among these 24 patients, 10 patients had metastatic lesions at pelvic lymphnodes (4), para- aortic lymphnodes (3), mediastinal lympnnodes (1), lung (4), and bone (1). Among 14 patients with no metastasis, 10 patients underwent surgical treatment but the operations were abandoned in 2 patients due to lymphnodes metastasis and pelvic peritoneal spreads that confused as normal FDG uptake of the intestines pre- operatively. Among 8 patients whom the operation was completed, 3 patients received pelvic exenteration, 2 patients received CORT, and 3 patients received LEER. CONCLUSION: FDG-PET is clinically feasible in selection of patients with pelvic recurrence of cervical cancer for surgical treatment.

Arotinolol was administered orally to 31 patients to evaluate is antihypertensive action. After one week of antihypertensive medication, they were given Arotinolol 30mg daily for 4 week. Routine serum chemistries, electrolytes, urinalysis and electrocardiography were studied before and after Arotinolol. Blood pressure measured in sitting, supine and standing position was 175.3+/-5.4/115.7+/-4.0, 168.0+/-5.2/150.0+/-3.8, 154.4+/-8.5/103.4+/-3.2mmHg in control and 143.8+/-2.8/93.3+/-2.8, 144.6+/-5.4/88.1+/-4.3, 139.7+/-4.6/86.8+/-3.4mmHg in Arotinolol treatment group. The differences between both blood pressure were statistically significant(P<0.01). No laboratory test showed significant difference between both period. There were no significant side effects except 2 cases of transient headache and dizziness respectively, and one case of diarrhea. In summary, Arotinolol apears to reduce blood pressure effectively with minimal side effects.

OBJECTIVE: The study was performed to evaluate whether thallium reinjection (RI) distinguishes viable from nonviable myocardium among myocardial segments which showed persistent perfusion defect (PD) in patients with acute myocardial infarction (AMI). MATERIALS AND METHODS: We studied 22 patients underwent PTCA after AMI. SPECT was performed in all patients using dipyridamole stress- 4 hour redistribution (RD) followed by 24 hour RI protocols. Dysfunctional segs were classified into 5 groups: 1) normal, 2) reversible, 3) mild to moderate PD, 4) severe PD and 5) reverse redistribution (RR). All patients underwent follow up echocardiography after 4 months to assess regional wall motion (WM) improvement such as a criteria of viable myocardium. RESULTS: A total of 127 segs with abnormal WM was analyzed. Of 74 segs with PD, 17 (23%) showed enhanced uptake after 24 hour RI. Five of 17 segs (29%) with PD that responded to RI with enhanced thallium uptake showed WM improvement. WM improvement were seen in the 24 of 57 segs (42%) not responding to RI. All four segs (100%) with RR that responded to RI showed improvement. WM improvement were not seen in the 5 of 8 segs (71%) with RR not responding to thallium RI. Eleven (73%) of 15 segs with mild-moderate PD after RI showed improvement, but 33% of segs with severe PD after RI did not showed improvement. Segs with mild-moderate PD after RI and fill in after RI showed improvement in comparison to segs with severe PD after RI(p<0.05). CONCLUSIONS: These data indicate that because only small proportion of PD showed further perfusion improvement after RI and predictive value by the uptake after RI was low, there was limited role of RI after myocardial infarction. Usefulness of RI could be found in segs showing RR responding to RI in AMI reflects viable myocardium.

BACKGROUND: There were many studies about the changes of cognitive or non-cognitive domain and behavioral and psychological symptoms with the progression of Alzheimer's disease. But they assessed the changes individually so could not explain comprehensively the global change of disease progression. Also they studied by clinical dementia rating scale(CDR) which could not successfully explain the latest stage. So we have evaluated the cognitive, non-cognitive domain and behavioral and psychological symptoms at the same time and evaluated the changes with the expanded clinical dementia rating scale. Also we evaluated the relationship of each scale and assessed sensitivity change at the different stage of disease. METHODS: Twenty-three mild cognitive impairment(MCI) subjects and eighty-seven patients with Alzheimer's disease were recruited. The Korean version of Mini-Mental State Examination(K-MMSE), the Korean version of the neuropsychiatric inventory(NPI), the Extended version of the Korean Clinical Dementia Rating Scale(CDR), the Activity of Daily Living(ADL), the Severe Dementia Scale(SDS) and the Short form of Samsung Dementia Questionnaire(S-SDQ) were performed. RESULTS: It was found that all of them were well correlated each other(r>-0.73 and p<0.05) except NPI. Physical activity of daily living(P-ADL) was most related to Korean version of instrumental activity of daily living(K-IADL) (r=0.86 and p<0.01), SDS to K-MMSE(r=0.93 and p<0.01) and S-SDQ to K-IADL(r=0.86 and p<0.01). P-ADL and S-SDQ revealed the ceiling effect at CDR 4 and K-IADL at CDR 3. CONCLUSION: The cognitive and non-cognitive function were declined according to disease progression. The changes of behavioral and psychological symptoms were relatively independent of cognitive function. SDS, P-ADL and CDR were proved to be more sensitive in advanced stage of dementia and K-IADL, S-SDQ were more adequate in milder stage of dementia or MCI.
