The purpose of this study is to find out the factors that affect the prognosis of conduct disorder in the adolescents. According to the nature or behavioral problems during 6 months after discharge, the good prognosis group(N=37) and the poor prognosis group(N= 36) were selected and scores of Youth Self Report(YSR), MMPI, KWIS were compared between both groups. The following results were obtained. 1) In family environmental factors, no significant difference was found between both groups. 2) In YSL total problem score, score of externalizing syndrome and score of delinquent behavior were significantly higher in the poor prognosis group. 3) In MMPI, no significant difference was found between both groups. 4) In KWIS, total 1.0. did not show significant differences between both groups. Our hypothesis that the prognosis of conduct disorder in adolescent is poorer in cases with higher quantities of problematic behaviors is certified.

Objectives : This study was conducted to evaluate the association between first episode polarity of pediatric bipolar disorder and prognosis. Methods : We analyzed the clinical records of 66 inpatient subjects with DSM-IV defined pediatric bipolar disorder. The patients were split into 2 groups according to the polarity of the illness onset [depressive onset (DO) vs. manic/hypomanic/mixed onset (MO)]. Clinical feature and prognosis were compared between the two groups of patients. Results : In our sample, 68% of patients experienced a depressive onset. In DO patients, rates of suicidal attempt, episodic illness course and comorbid disruptive behavior disorder were higher than rates in MO patients. Conclusion : Findings from this study suggest that polarity of illness onset may be useful in predicting the prognosis of pediatric bipolar disorder.

Recently, the cardiovascular disease has increased by causes such as westernization dietary life, smoking, and obesity. In particular, the acute myocardial infarction (AMI) occupies 50% death rate in cardiovascular disease. Following this trend, the AMI has been carried out a research for discovery of risk factors based on national data. However, there is a lack of diagnosis minor suitable for Korean. The objective of this paper is to develop a classifier for short-term relapse mortality prediction of cardiovascular disease patient based on prognosis data which is supported by KAMIR(Korea Acute Myocardial Infarction). Through this study, we came to a conclusion that ANN is the most suitable method for predicting the short-term relapse mortality of patients who have ST-segment elevation myocardial infarction. Also, data set obtained by logistic regression analysis performed highly efficient performance than existing data set. So, it is expect to contribute to prognosis estimation through proper classification of high-risk patients.

Pompe disease is a rare lysosomal glycogen storage disorder caused by a total or partial deficiency of the acid ${\alpha}$-glucosidase (GAA) enzyme due to the GAA gene mutations. The classic infantile form of Pompe disease is a rapidly progressive multi-organ disease with hypotonia, generalized muscle weakness, and hypertrophic cardiomyopathy, usually leading to death in the first 2 years of life. Enzyme replacement therapy with recombinant human GAA has been shown to be effective and subsequently yielded promising results. Here, we present clinical and genetic characteristics of three Korean non-classic infantile Pompe patients, and the short term efficacy of enzyme replacement therapy. Considering that enzyme replacement therapy can change the natural course of infantile Pompe disease, early diagnosis and early initiation of treatment is critical to improving patient outcomes.

Background: The treatment results of the advanced lung carcinoma is not satisfactory with the present therapeutic modalities: surgical resection, anti-cancer chemotherapy, and radiotherapy or combination therapy. To predict the prognosis of the non-small-cell lung carcinoma, TNM classification has been was as the basic categorization; however, it has been not satisfactory. It is necessary to consider the causes and the prognosis of the lung carcinoma from another points of view rather the conventional methods. We intended to find out the relationship between the major apoptotic factor, p53 gene and the prognosis of the patient with lung carcinoma. Material and Method: Three hundreds and fifty-nine patients with lung carcinoma who underwent surgery were analysed. We observed p53 protein accumulated in the cellular nuclei. The p53 protein was detected by immuno-histo-chemical method. We collected information of the patient retrospectively. Result: p53 protein densities were observed in 40% in average as a whole. The protein density was 44 percent in man, 25 percent in woman, 49 percent in the squamous cell carcinoma, and 38 percent in the adenocarcinoma. There were significant correlations between the p53 protein density and the mortality in the squamous cell carcinoma (p=0.025), follow-up duration in TNM stage I group (p=0.010), and follow-up duration in the lobectomy patient group (p=0.043), and tumor cell differentiation (p=0.009). p53 protein densities were significantly different between the lobectomy and the pneumonectomy group (p=0.044). Conclusion: The authors found that p53 protein had some correlations with the prognosis of the lung cancer partially in some factors. We suggest the p53 protein density could be used as a marker of prognosis in the non-small-cell lung carcinoma.

All ceramic restorations except In-Ceram Alumina system gave a good esthetics and an exellent marginal fidelity. The flexural strength of them had about 150MPa, so the indication is only single crown. By using In-ceram Alumina System(450Mpa), it is thought to be possible to construct bridge for its high flexural strength. But the prognosis is unclear, The purposes of this study are to clear short term prognosis of In-Ceram bridge restorations, to elucidate its clinical significance. Among 22 In-Ceram Bridge restored in our department, 11 In-Ceram bridges with follow up were used. The period of placement is from 1 to 18 months. The results were as follows : 1. Among follow up 11 bridges, 2 bridges were fractured. One is 4 unit in maxillary lateral incisors, the other is 3 unit bridge in maxillary canine and premolar. Including 11 bridge without follow up, failure rate is very low(2/22). 2. The fracture sites are connector areas between abutment and pontic. To maintain In-Ceram bridge for long term period, it is needed to remove the nonphysiologic occlusal force and to have sufficient thickness of alumina core. For estabilishing clinical use of In-Ceram bridges, it is thought to need clinical research during long term period.

Background : Idiopathic pulmonary fibrosis (IPF) is a fatal progressive fibrous disease of the lung of unknown etiology. Recently it has been classified into several distinct entities on the basis of pathologic and clinical characteristics, ie : usual interstitial pneumonia (UIP), desquamative interstitial pneumonia (DIP), acute interstitial pneumonia (AIP), bronchiolitis obliterans with organizing pneumonia (BOOP), and nonspecific interstitial pneumonia (NSIP). IPF is now applied only for UIP, which has the worst prognosis. The previous reports of 3-5 year median survival appears to be overoptimistic because other types with better prognosis like NSIP or BOOP might have been included. Therefore, this study was performed to determine the clinical course and the prognostic factors of UIP as diagnosed by surgical lung biopsy. Methods : The subjects were 72 UIP patients (age $58.2{\pm}11.6$ years, M : F=45 : 27, median follow up period : 18.1 months (0.7-103.6) diagnosed by surgical lung biopsy at the Asan Medical Center (68 patients) and the Paik Hospital in Seoul (4 patients). Clinical scores (level of dyspnea : 1-20 points), radiologic score (honeycombing : HC score 0-5 points, ground glass : GG score 0-5 points), and physiologic scores (FVC : 1-12 points, $FEV_1$ : 0-3 points, TLC : 0-10 points, $D_{LCO)$ : 0-5 points, $AaDO_2$ : 0-10 points) were summed into a total CRP score. Results : 1) The one year survival rate was 78.3%, while the rate for three year survival was 58.1%, and the median survival period was 42.5months. 2) Short term (1 year) prognosis : The patients who died within one year of diagnosis (14 patients) had the higher initial total CRP score ($28.6{\pm}8.3$ vs. $16.6{\pm}9.7$) than those who lived longer than one year (46 patients). The difference in the total CRP score was attributed to the symptom score ($8.4{\pm}2.1$ vs. $5.7{\pm}3.9$) and the physiologic score ($15.7{\pm}7.1$ vs. $6.7{\pm}5.7$) including FVC, $D_{LCO)$ and $AaDO_2$. 3) Long-term (3year) prognosis : The total CRP score ($12.2{\pm}6.7$ vs. $28.7{\pm}7.9$ : including symptom score, FVC, $D_{LCO)$ and $AaDO_2$) at the time of diagnosis were also different for the long-term survivors and those who lived less than 3 years. 4) Cox regression analysis showed $D_{LCO)$ (${\geq}$60%) (Hazard ratio : 4.56, 95% CI : 2.30-16.04) was the independent prognostic factors of UIP (P<0.05). Conclusion : These results suggest that $D_{LCO)$ at the time of diagnosis seem to be a prognostic markers of biopsy-proven UIP.

Purpose : Clinicopathological features were investigated to clarify the outcome and prognostic indicators for patients with IgA nephropathy in Korean children. Methods : We reviewed the outcomes of 61 patients in whom IgA nephropathy was diagnosed before the age of 15 years from 1991 to 2005 and followed-up at least for one year. All patients were confirmed by renal biopsy. Results : After mean follow-up of 5.2 years from onset, 24 patients of 61 (39.3%) were in clinical remission at the last examination. Thirty patients (49.2%) had hematuria or mild proteinuria (<$1g/m^2/d$), five (8.2%) had severe proteinuria (${\geq}1g/m^2/d$), and two (3.3%) had chronic renal failure. By univariate analysis, initial presentation at onset and Haas classification were less concordant with outcome. Hypertension during follow-up, rather than hypertension at presentation, was significantly correlated with outcomes (P<0.01). Sixty percent of patients who had more than 20% of glomerular sclerosis or crescent progressed to severe proteinuria or chronic renal failure, as compared with 7.1% of those who did not (P<0.01). Conclusion : Prognosis of childhood IgA nephropathy had a relatively benign course during a mean follow-up of 5.2 years. Persistent hypertension during follow-up and more than 20% of glomerular sclerosis or crescent were strong predictors of a progressive course of IgA nephropathy. A new histologic classification according to characteristics of childhood IgA nephropathy must be established to assess prognosis. Further efforts should be made to understand the prognosis of IgA nephropathy through long-term follow-up.

This study evaluated the improvement of autistic symptoms during the 4-7 year follow-up in autistic children. Fifty subjects(44 males and 6 females whose age ranged between one to 13 years) diagnosed with DSM-III-R autistic disorder were included in this study. Their autistic symptoms were assessed with DSM-III-R diagnostic criteria of autistic disorder(grouped as A, B and C which include 5, 6 and 5 items respectively). The mean of follow-up duration was 6.4${\pm}$1.1 years. Symptoms between baseline and follow-up were examined according to treatment types, age, sex, IQ and physical problems of them were identified. There were statistically significant decreases of symptom items at follow-up as a whole and A, B and C, respectively. The most symptom decrease occurred in communication and followed social interaction, and activities and interests at follow-up assessment. Symptom items that decreased more than 50% at follow-up evaluation include A1, A2, A3 and B1, B2, B3, B4, B5, and C1, C3. Groups with special education only and combined treatment of special education and seizure pharmacotherapy showed better improvement of symptoms than the group with psychiatric pharmacotherapy with special education. Age was a significant factors in the improvement of symptoms. The author concluded that some autistic children improved with aging, therefore they should be treated actively with special education, pharmacothrapy and other scientific methods.
