Purpose :We peformed the retrospective analysis to find the outcome of external beam radiotherapy alone in advanced esophageal cancer patients. Methods and Materials : One hundred and six Patients treated with external beam radiotherapy alone between July 1990 and December 1996 were analyzed retrospectively. We limited the site of the lesions to the thoracic esophagus and cell type to the squamous cell carcinoma. Follow-up was completed in 100 patients (94$\%$) and ranged from 1 month to 92 months (median; 6 months). Results :The median age was 62 years old and male to female ratio was 104 2. Fifty-three percent was the middle thorax lesion and curative radiotherapy was peformed in 83$\%$. Mean tumor dose delivered with curative aim was 58.6 Gy (55$\~$70.8 Gy) and median duration of the radiation therapy was 53 days. The median survival of all patients was 6 months and )-year and 2-year overall survival rate was 27$\%$ and 12$\%$, respectively, Improvement of dysphagia was obtained in most patients except for 7 patients who underwent feeding gastrostomy. The complete response rate immediately after radiation therapy was 32$\%$ (34/106). The median survival and 2-year survival rate of the complete responder was 14 months and 30$\%$ respectively, while those of the nonresponder was 4 months and 0$\%$ respectively (p=0.000). The median survival and 2-year survival rate of the patients who could tolerate regular diet was 9 months and 16$\%$ while those of the patients who could not tolerate regular diet was 3 months and 0$\%$, respectively (p=0.004). The survival difference between the patients with S cm or less tumor length and those with more than 5 cm tumor length was marginally statistically significant (u=0,06). However, the survival difference according to the periesophageal invasion or mediastinal tyrnphadenopathy in the chest CT imaging study was not statistically significant in this study. In a multivariate analysis, the statistically significant covariates to the survival were complete response to radiotherapy, tumor length, and initial degree of dysphagia in a decreasing order. The complication was observed in 10 patients (9$\%$). Conclusion :The survival outcome for advanced esophageal cancer patients treated by external beam radiotherapy alone was very poor. In the treatment of these patients, the brachytherapy and chemotherapy should be added to improve the treatment outcome.

Purpose : To evaluate the significance of clinical signs and laboratory findings as predictors of renal parenchymal lesions and vesicoureteral reflux (VUR) in childhood urinary tract infection (UTI). Methods : From July 2005 to July 2008, 180 patients admitted with a first febrile UTI at the Pediatric Department of Konkuk University Hospital were included in this study. The following were the clinical variables: leukocytosis, elevated C-reactive protein (CRP), positive urine nitrite, positive urine culture, and fever duration both before and after treatment. We evaluated the relationships between clinical variables and dimercaptosuccinic acid (DMSA) scan and voiding cystourethrography (VCUG) results. Results : VCUG was performed in 148 patients; of them, 37 (25.0%) had VUR: 18 (12.2%) had low-grade (I-II) VUR, and 19 (10.5%) had high-grade (III-V) VUR. Of the 95 patients who underwent DMSA scanning, 29 (30.5%) had cortical defects, of which 21 (63.6%) had VUR: 10 (30.3%), low-grade (I-II) VUR; and 11 (33.3%), high-grade VUR. Of the 57 patients who were normal on DMSA scan, 8 (14.0%) had low-grade VUR and 6 (10.5%) had high-grade VUR. The sensitivity, specificity, and positive and negative predictive values of the DMSA scan in predicting high-grade VUR were 64.7%, 69.9%, 33.3%, and 89.5%, respectively. Leukocytosis, elevated CRP, and prolonged fever ($36{\geq}$ hours) after treatment were significantly correlated with the cortical defects on DMSA scans and high-grade VUR. Conclusion : Clinical signs, including prolonged fever after treatment, elevated CRP, and leukocytosis, are positive predictors of acute pyelonephritis and high-grade VUR.

Purpose : Development of renal scarring is associated with delayed diagnosis and treatment of urinary tract infection(UTI). This study was performed to clarify how soon treatment should be started to Inhibit renal scarring after onset of UTI and the factors associated with renal scarring in children with a first episode of febrile UTI. Methods : We retrospectively reviewed 163 patients with a first episode of febrile UTI under the age of 2 years from April 2000 to Ap,il 2004. All patients had a DMSA renal scan and voiding cystourethrogram done in the diagnostic period, 6 months after which a follow-up renal scan was done. After patients wet-e divided into 2 groups according to the duration of fever prior to start of treatment, the duration of fever after start of treatment, and total duration of fever, initial and follow-up DMSA scan findings were analyzed among the different groups. We compared the factors associated with renal scars between the groups with and without renal scars. Results : The initial DMSA renal scan identified abnormal finding in 23% of the patients who were treated $\leq$24 hr from the onset of disease and in 43% of those with fever more than 24 hr. Renal scars developed in 33% of patients who were treated $\leq$24 hr and 38% of those with fever >24 hr prior to treatment. Renal scars developed in 34% of patients with remission of fever $\leq$48 hr after treatment and ill 50% of those with fever >48 hr after treatment. The risk for renal scars was significantly higher in children who had total duration of feyer >72 hr(67%) than in those with shorter duration(19%). In children with renal scars, VUR was most highly associated with an increased risk of renal scar formation. Conclusion : Although children with a first episode of febrile UTI are treated within 24 hr after onset of the fever, renal damage cannot be prevented completely and it is mainly associated with VUR.

The purpose of this study was to evaluate the changes of skeletodental patterns during Class II treatment and its retention period. Forty two patients of Class II malocclusion, which was treated with nonextraction or first premolar-extraction were selected and their lateral cephalograms were examined in this study. Various skeletodental changes in lateral cephalograms of pre-treatment, post-treatment and retention were measured by superimposition in reference to the cranial base for jaws, the palatal plane for maxillary teeth, and mandibular plane for mandibular teeth. The data were analyzed by paired t-test. In this study, occlusal plane showed the significant anterior downward steepening after active treatment, and remained during retention period. In the nonextraction group, maxillary incisors were retracted and extruded during treatment. Maxillary molars were extended, and mandibular molar were uprighted, with no mesial movement. In the extraction group, both maxillary and mandibular incisors were retracted and extruded. Maxillary molars were extruded and moved mesially, and mandibular molars were extruded and moved mesially with no mesial tilting. During retention period in both groups, there were tendencies of labial tipping of maxillary incisor, and mesial tipping of maxillary and mandibular molar. But the changes were not significant and most of teeth showed no change in vortical and horizontal direction.

Purpose : The aim of this study was to investigate treatment results, toxicity and efficacy of hypefractionated radiation therapy combined with paclitaxel for paraaortic node recurrence in cervix cancer. Materials and Methods: Between September 1997 to March 1999, 12 patients with paraaortic node recurrence in cervix cancer who previously received radical or postoperative radiotherapy were treated with hypefractionated radiation therapy combined with paclitaxel. Of these, 2 patients who irradiated less than 30 Gy were excluded, 10 patients were eligible for this study. Median age was 51 years. Initial FIGO stage was 1 stage IBI, 2 stage IIA, 7 stage IIB. For initial treatment, 7 patients received radical radiotherapy and 3 received postoperative radiotherapy. The paraaortic field encompassed the gross recurrent disease with superior margin at T12, and inferior margin was between L5 and S1 with gap for previously pelvic radiation field. The radiation field was initially anterior and posterior opposed field followed by both lateral field. The daily dose was 1.2 Gy, twice daily fractions, and total radiotherapy dose was between 50.4 and 60 Gy(median, 58.8 Gy). Concurrent chemotherapy was done with paclitaxel as a radiosensitizer. Dose range was from 20 mg/m$^{3}$ to 30 mg/m$^{3}$ (median, 25 mg/m$^{3}$), and cycle of chemotherapy was from 3 to 6 (median, 4.5 cycle). Follow-up period ranged from 3 to 21 months. Results : Interval between initial diagnosis and paraaortic node recurrence was range from 2 to 63 months (median, 8 months). The 1 year overall survival rate and median survival were 75$\%$ and 9.5 months, respectively. The 1 year disease free survival rate and median disease free survival were 30$\%$ and 7 months, respectively. At 1 month after treatment, 4 (40$\%$) achieved a complete response and 6 (60$\%$) experienced a partial response and all patients showed response above the partial response. There was distant metastasis in 6 patients and pelvic node recurrence In 2 patients after paraaortic node irradiation. There was 2 patients with grade 3 to 4 leukopenla and 8 patients with grade 1 to 2 nausea/ vomiting which was usually tolerable with antlemetic drug. There was no chronic complication in abdomen and pelvis during follow up period. Conclusion : hypefractionated radiation therapy combined with paclitaxel chemotherapy diosensitizer showed high response rate and few complication rate in paraaortic node recurrence in cervix cancer Therefore, present results suggest that hypefractionated radiation therapy combined with paclitaxel chemotherapy can be used as optimal treatment modality in this patients.

The main purpose of this study was to treat pica in a 2.8 year old child with severe mental retardation along with autistic tendencies. His developmental age ranged from 12 to 15 month on the DDST and he had no means of communication. He was on Tegretol 200mg for seizure control. His pica involved thumb sucking, putting toys into his mouth, and licking furniture wherever he went Besides pica, he had a rumination problem. The treatment strategies for his pica consisted of two phases : In phase 1, The child was taught toy play through a 3-step guided compliance training, while his pica and rumination behaviors were recorded to investigate whether active toy play could effect any change in the untreated pica and rumination behaviors of this child. In phase 2, a facial screening was used as a means to control his pica, while his rumination was recorded to see whether controlling his pica could bring any change in the untreated ruminating behavior. The results showed that the facial screening was very effective in decreasing his pica from an average of 18.6 times per 15 minute in the baseline to 2.3 times post-treatment. Response covariation was observed across pica and rumination while toy play compliance training alone was being conducted, and covariation across rumination was observed while pica alone was being treated with facial screening.

Gastric cancer is not a single, uniform disease, but rather heterogeneous in nature. It is generally not possible to cure patients with inoperable advanced or metastatic stomach cancer. In the absence of chemotherapy, the median survival time is 3 to 6 months. Therefore, several studies have confirmed the superiority of chemotherapy to the best supportive treatment, in terms of improving the quality of life and prolonging life. Various chemotherapies have been used in the past to treat advanced gastric cancer. Recently, various target therapies and immunotherapy have been introduced. However, compared to other malignancies, the quality of life and life expectancy remain relatively poor in patients with gastric cancer. We expect to overcome these difficulties in the future, with better elucidation of the molecular biology of gastric cancer.

Purpose : To assess the clinical features and laboratory findings in Kawasaki patients with nonresponsibility to the acute antiinflammatory treatment, and identify the risk factors for the nonresponsibility, we reviewed the medical records of patients with Kawasaki disease. Methods : A retrospective study of 177 patients with Kawasaki disease at Wonkwang University Medical Center from June, 1997 to June, 2002, was performed. High dose intravenous immune globulin(IVIG) and aspirin were all used for the initial acute antiinflammatory treatment. Two groups, group A(n=19) of initial nonresponders and group B(n=158) of initial responders were compared clinically and laboratorically. Results : Nineteen(10.7%) of 177 patients hardly responded to the initial antiinflammatory treatment. Patients with failure to respond to initial treatment(group A) did not differ from the control group in terms of age, sex, WBC count, coronary abnormalities, and evidence of pyuria. Compared with initial responders(group B), the patients who were retreated(group A) had a significantly shorter feveradmission interval(P=0.041), and a higher level of both AST/ALT(P=0.011) and ASO titier(P=0.000). Conclusion : Among Kawasaki disease patients studied, retreatment group with initial nonresponders had significantly shorter fever-admission interval, and higher both AST/ALT level and ASO titer, than the initial response group.
