Thirty-five patients with locally advanced gastric carcinoma were treated with combined modalities of external radiation therapy (RT) and 5-FU based chemotherapy at the Division of Radiation Therapy, Department of Radiology, Kangnam 51. Mary's Hospital, Catholic University Medical College from May 1983 to May 1987. The purpose of this retrospective study is for the evaluation of the palliative response to RT. There were 25 men and 10 women. The age ranged from 38 to 80 years (median: 56 years). The pathologic classification showed $14(40\%)$ poorly differentiated, $12 (34\%)$ moderately differentiated, $3(9\%)$ well differentiated adenocarcinomas, 2 mucinous cystadenocarcinomas, 1 signet ring cell and 3 not specified ones. The time intervals from the initial surgicopathologic diagnosis to the starting day of RT was within 1 year for $18 (51\%)$, 1 to 2 years for $8 (23\%)$ and 2 to 3 years for $5 (14\%)$, respectively. The major symptoms to be treated were pain in $30 (80\%)$, mass for $29 (83\%)$, obstruction for $11 (31\%)$ and jaundice for $9 (20\%)$ patients. The response rate (patient number of positive response/total patient number) according to treated radiation doses were observed as follows; $14/16(88\%)$ for $40\~50Gy,\;8/10(80\%)$ for over $50Gy,6/8 (75\%)\;for\;30\~40Gy\;and\;8/10(53\%)\;for\;20\~30 Gy$ in decreasing order. The over ail survival was 3.0 months and that of 5FU+RT, FAM+RT and RT alone groups were 4.6 months, 3.7 months and 2.5 months respectively. Complications induced by RT were nausea and vomiting in $16(46\%)$, diarrhea in $7(20\%)$, leukopenia in $6(17\%)$ and anemia and intercurrent pneumonia in each $3(9\%)$ patients in decreasing order.

Purpose : In previous studies, various risk factors for recurrent febrile seizures have been identified. But none of these risk factors alone could sufficiently discriminate children at high or low risk for recurrent seizures. Therefore, we tried to identify patients at high risk of recurrent febrile seizures by combining risk factors. Methods : Two hundred and four children who had been admitted to our hospital from March, 1997 to July, 1999 with their first febrile seizures were enrolled in our study, and followed up over 2 years. We investigated the recurrence rate according to variables such as sex, age at first febrile seizure, family history of febrile seizures or epilepsy, type of the first seizure, neurologic abnormality and EEG abnormality. Results : Family history of febrile seizures and age at first febrile seizure(<12 months) were significant independent risk factors for recurrent febrile seizures. With these two combined factors, four groups were allocated and the recurrence rate by each group was designated as follows: group with no family history of febrile seizures and age at first febrile seizure ${\geq}12$ months (no risk factor), 43.8%; the group with no family history and age <12 months(one risk factor), 61.7%; group with family history and age ${\geq}12$ months(one risk factor), 64.5%; group with family history and age <12 months(two risk factors), 90.4%. Conclusion : A correlation between numbers of risk factors and recurrence rate was present and the children with a family history of febrile seizures and a young age at onset(<12 months) were regarded as a high risk group of recurrence.

From September 1992 to May 1996, 38 patients ranging in age from 23 to 78, were operated for aortic dissection at Asan medical center There were 21 men and 17 women. The underlying aortic pathology were acute aortic dissection in 23, chronic aortic dissection in 15. Eight patients had Martian syndrome. In 34 cases of DeBakey type I, II patients, femoral artery and vein and/or right atrial auricle were used as cannulation site. With deep hypothermic c rculatory arrest (esophageal temperature 12 $\pm$ 2.5$^{\circ}C$) and retrograde cerebral perfusion of cold oxygenated blood through SVC, we replaced the ascending aorta and the part of arch if necessary. The mean duration of the total circulatory arrest time was 25 $\pm$ 1.7 mintstuts. In 4 cases of DeBakey type III patients, we replaced descending thoracic aorta or thoracoabdomlnal aorta without shunt or bypass under normothermia with an average 30: 1.5 minutesaortic cross clamp time. One death(2.6%) occurred on the twenty-second postoperative day owing to asphyxia related to ulcer bleeding. Postoperative complications were myocardial infarction with transient left peroneal palsy in 1 case, transient lower extremity weakness in 1 case and prolonged ventilatory support in 1 case. Two patients required reoperation due to retrograde extended dissection and aortic insufuciency. There was no late death with an average 25 months follow-up period.
