Serial neurosonographic examinations are routinely performed at frequent intervals during nursery course of all preterm infants of very low-birth-weight who are admitted to the intensive care nursery of Presbyterian Medical Center from November 1, 1990 to July 30, 1992. After discharge, the following survivors who had received periodic, serial scanning by meas of cranial ultrasonography were longitudinally observed in an interdisciplinary neurodevelopmental follow-up program to a mean corrected age of 13 months. Neurodevelopmental outcome was assessed by means of Vojta's postural reaction and other neurological examinations. The results are as follows: 1) The incidence of PV-IVH in the study was 79%. 2) According to Papile's grading system of PV-IVH, gradel was 20%, gradell was 46%, gradelll was 19%, and grade IV was 13%. 3) The risk factors associated with PV-IVH were birth weight, gestational age, apgar score, ventilator care, RDS, and sepsis. 4) The mortality of PV-IVH was 20% for gradel, 19% for gradell, 44% for gradelll, and 67% for grade lV. 5) According to relationship between PV-IVH and neurodevelopmental outcome, in two of the four subjects with grade lll PV-IVH, moderate/severe CCD was developed. 6) According to relationship between PVE with cysts and nuerodevelopmental outcome, moderate/severe PVE with periventricular cysts larger than 3mm in diameter was associated with development of severe CCD.

PURPOSE: To investigate the risk factors of recurrence after their first febrile convulsions. And to evaluate effect of anticonvulsant therapy with recurrent febrile convulsion infants and children. METHODS: We have studied the relationship of their clinical pictures and factors related to the risk of recurrence of 178 patients with primary or recurrent febrile convulsion, who were admitted to department of pediatrics, or visited to emergency room, chonju presbyterian medical center from january 1983 to december 1992. The 178 patients were followed up and consisted of the 97 patients with primary febrile convulsion and the others 81 patients with recurrent febrile convulsions. RESULTS: 1) In sex distribution, the boys(59%) outnumbered the girls(41%) and the ratio was 1.4:1. 2) 95% of overall patients were occurred febrile convulsion under 5 year-old and recurrent rate was 45.5%. In recurrent cases, the first episode under the 12 months was 50.6%(p<0.005). 3) There were family history of febrile convulsion in 28.4% of recurrent cases, compared to 10.9% of primary cases(p<0.001). 4) There was no significant difference with duration and type of convulsion in both groups. 5) Small proportion of 27 children were prescribed anticonvulsants (phenobarbital), but it's not reduced the recurrence and epilepsy significantly. CONCLUSIONS: The risk factor of recurrent febrile convulsion were the first episode under 12 month and familial history of febrile convulsion.

PURPOSE: We evaluated the efficancy of low contact stress (LCS) system in total knee arthroplasty by analyzing clinical and radiological results. MATERIAL AND METHOD: Total knee arthroplasty was performed on 194 patients with 280 knees by the senior author between January 1995 and August 2002, using the LCS system. We used the Hospital for Special Surgery knee rating scale, the range of motion, and radiographic evaluation. RESULT: The knee score was increased from average 48.4 points preoperatively to 84.8 points postoperatively. The flexion contracture was decreased from average 9.4 degrees preoperatively to average 2.8 degrees postoperatively. The further flexion was increased from average 102.2 degrees preoperative]y to 123.7 degrees postoperatively. The femorotibial angle was increased from average 6.2 degrees varus preoperatively to average 6.3 degrees valgus postoperatively. There were 3 fractures of meniscal bearing, 10 superficial infection cases, 3 deep infection cases and 2 peroneal nerve palsy. CONCLUSION: We reported that good and excellent clinical results (95%) were obtained in the patients who had arthroplasties with the LCS mobile bearing system.

BACKGROUND/AIMS: Liver cirrhosis is an end-stage liver disease. Ito cell is known to have central role in fibrogenes is of liver cirrhosis. But collagen content and Ito cell activity in liver cirr hosis have received little attention. So Ito cell activity and hepatocyte proliferation activity according to collagen content was investigated. WAF-1 and c- met were studied to evaluate the effect of cell cycle. METHODS: We analyzed 56 cases of liver cirrhosis ( viral:41, biliary:11, alcoholic:2, Wilson' s disease:2). Collagen content was measured by spectrophot ometry. Ito cell activity and prolifer ation index was measured by-SMA and Ki- 67 immunohistochemistry. RESULTS: In viral cirrhosis, high collagen group showed increased Ito cell activity compared to low collagen group. There was no difference in hepatocyte prolifer ation activity bet ween high and low collagen group in viral cirrhosis. In biliary cirrhos is, high collagen group showed increased Ito cell activity in septal zones compared to low collagen group. WAF- 1and c- met were negative in most of cases. CONCLUSION: Collagen content of liver cirrhosis is closely related to increment of activated Ito cells . Ito cell activity was prominent in septal zones than in parenchymal areas of viral cirrhosis and that was only significant in septal zones of biliary cirrhosis. There is no correlation bet ween collagen content and hepatocyte proliferation activity.

This study was planned to evaluate the efficacy and toxicity of fosfamide/mesna plus cisplatin combined regimen in patients with recurrent and initial therapy-resistant epithelial ovarian cancer. Controversy still remains over the efficacy of cisplatin containing combined chemotherapy as the treatment of recurrent ovarian cancer and refractory to first line chemotherapy. Ifosfamide(isophosphamide) is an analog of cyclophosphamide. It has shown evidences of activity in ovarian cancer and lack of cross-resistance with cyclophosphamide. This study was undertaken for the clinical analysis and evaluation on 16 patients, who were admitted and treated with advanced or recurrent ovarian cancer at the Sooncheunhyang University Chunan Hospital from January 1994 to July 1996. The results were as follows: 1. The mean age of patients was 62 year old with range from 44 to 72. 2. The most frequent side effect was nausea and vomiting(75%), followed by leukocytopenia(68%), alopecia(44%), nephrotoxicity(37%), neurotoxicity(25%), and hepatotoxicity(12%). 3. The mean survival period was 24 months in clinical response cases ranged from 11 months to 36 months, 5 months in progressive cases ranged from 1 month to 14 months. 4. In clinical stages, stage II was 6 cases(37.5%), III was 6 cases(37.5%) and IV was 4 cases(25%). 5. Previously all patients were received debulking surgery and PAC hemotherapy. 6. Overall respons rate was 44%(7/16).

Background/Aims: Recent advances in understanding the genetics of pancreatic ductal adenocarcinoma (PDAC) have led to the potential for a personalized approach. Several studies have described the feasibility of generating genetic profiles of PDAC with next-generation sequencing (NGS) of samples obtained through endoscopic ultrasound-guided tissue acquisition (EUS-TA). The aim of this study was to find the best EUS-TA approach for successful NGS of PDAC. Methods: We attempted to perform NGS with tissues from 190 patients with histologically proven PDAC by endoscopic ultrasound-guided fine-needle aspiration and endoscopic ultrasound-guided fine-needle biopsy at Samsung Medical Center between November 2011 and February 2015. The medical records of these patients were retrospectively reviewed for parameters including tumor factors (size, location, and T stage), EUS-TA factors (needle gauge [G], needle type, and number of needle passes) and histologic factors (cellularity and blood contamination). The sample used for NGS was part of the EUS-TA specimen that underwent cytological and histological analysis. Results: NGS could be successfully performed in 109 patients (57.4%). In the univariate analysis, a large needle G (p=0.003) and tumor located in the body/tail (p=0.005) were associated with successful NGS. The multivariate logistic regression analysis revealed that the needle G was an independent factor of successful NGS (odds ratio, 2.19; 95% confidence interval, 1.08 to 4.47; p=0.031). Conclusions The needle G is an independent factor associated with successful NGS. This finding may suggest that the quantity of cells obtained from EUS-TA specimens is important for successful NGS.

We evaluated the antihypertensive effect of amlodipine, a calcium channel bloker, in 35 cases of essential hypertention. After 12 weeks' administration(5~10mg q.d.), the following results were obtained : 1) The systoloic and diastolic blood pressure were decreased significantly(170.3+/-12.2mmHg vs 143.7+/-13.0mmHg p<0.01 and 104.7+/-5.9mmHg vs 87.8+/-6.5mmHg, p<0.01, respectively) but the heart rate was independant of amlodipine administration. 2) The systolic blood pressure was lowered by 20mmHg or more in 26(76.5%) of 34 patients and the diastolic pressure was lowered by 10mmHg or more in 26(76.5%) of 34 patients at 12 weeks after amlodipine administration. 3) The adverse effects of amlodipine were dizziness in 5, edema in 5, indigestion in 3, constipation in 2, headache, flushing, insomnia in 1 patient respectively and only one of them discontinued amlodipine administration due to severs facial flushing and skin eruption.

PURPOSE: Colorectal cancer (CRC) has a high risk for postoperative thromboembolic complications such as venous thromboembolism (VTE) compared to other surgical diseases, but the relationship between VTE and CRC in Asian patients remains poorly understood. The present study examined the incidence of symptomatic VTE in Korean patients who underwent surgery for CRC. We also identified risk factors, incidence and survival rate for VTE in these patients. MATERIALS AND METHODS: The patients were identified from the CRC database treated from January 2011 to December 2012 in a single institution. These patients were classified into VTE and non-VTE groups, their demographic features were compared, and the factors which had significant effects on VTE and mortality between the two groups were analyzed. RESULTS: We analyzed retrospectively a total of 840 patients and the incidence of VTE was 3.7% (31 patients) during the follow-up period (mean, 17.2 months). Histologic subtype (mucinous adenocarcinoma) and previous history of VTE affected the incidence of VTE on multivariate analysis. There was a statistically significant difference in survival rate between the VTE and non-VTE group, but VTE wasn't the factor affecting survival rate on multivariate analysis. Comparing differences in survival rate for each pathologic stage, there was only a significant difference in stage II patients. CONCLUSION: Among CRC patients after surgery, the incidence of VTE was approximately 3% within 1 year and development of VTE wasn't a significant risk factor for death in our study but these findings are not conclusive due to our small sample size.

PURPOSE: Over the several decades, there has been a considerable improvement in the survival of patients who undergo renal transplantation due to newer immunosuppressive agents and development of surgical technique and post-operative management. However, life expectancy beyond 10 years is still considerably less than that in the general population. We studied the causes of patient death after kidney transplantation to determine the major causes of death, to decrease the mortality rate of patient and to increase the graft survival rate. METHODS: From Jan. 1990 to Dec. 2002, 1353 renal transplantation were performed at Asan Medical Center. There had been 63 cases of patient death and we reviewed the causes of death, recipient-donor relationship, immunosuppressive agents, history of rejection and the time of death after transplantation in these patients, retrospectively. RESULTS: The major causes of patient death were infection (36.5%), cardiovascular disease (14.3%), malignancy (9.5%), hepatic failure (11.1%), miscellaneous (11.1%) and unknown (22.2%). Thirty-nine (61%) of total death occurred in the first year of transplantation and major cause in first year of transplants was infection (46.2%). Of 63 deaths, 35(55.6%) were with graft function and 49 (77.8%) had history of rejection. The patients with brain- death donor had a higher death rate than that of the patients with living donors (3.7% vs 7.8%, P=0.002). The patients who had history of rejection have higher death rate than the patient with no history of rejection (22.6% vs 1.3%, P<0.001). CONCLUSION: Active efforts for the prevention of rejection and infection in early phase of transplantation and close surveillance of malignancy and cardiovascular disease in long-term follow up will decrease the death of transplanted patients and increase the graft survival rate.
