PURPOSE: This study was conducted to examine the effect of a posture training program, including posture education and spinal exercise as implemented on the elementary school students with scoliosis. METHOD: The design of this study is nonequivalent sample control group pretest-posttest design. The study subjects were elementary school students attending 7 elementary schools located in G city in Gyungsangbuk-Do. Among them, those who had the Cobb angle between 4~10 in spine x-ray who agreed to participate in the study program were selected as the study subjects. The research instruments included the degree of spinal scoliosis(cobb angle), the level of knowledge on posture, and an evaluation following the posture training program. The data were collected from March 1, 2002 to July 30, 2002. The collected data were analyzed by frequency, percentile, mean, standard deviation, t-test, 2 test and Mann-Whitney U test were using SPSS WIN10.0 program. RESULT: The elementary school students with scoliosis who received the posture training program have a lower Cobb angle and higher level of knowledge of posture than the elementary school students with scoliosis who did not receive the posture training program. CONCLUSION: The posture training program was effective on the on Cobb angle and Knowledge of posture in the elementary school students with scoliosis in this study. Therefore, the program training program can be usefully utilized for the students with mild scoliosis in the field of school health.

PURPOSE: The purpose of this study was to evaluate the CT findings of acute pyelonephritis (APN) in children and to assess the correlation between these findings, clinical parameters and renal scar development, as seen on follow-up CT scans. MATERIALS AND METHODS: Contrast-enhanced CT scans of thirty children in whom APN had been diagnosed were assigned to one of three groups according to whether an abscess had formed, and then to subgroups on the basis of the number of lesions in the renal parenchyme. Initial CT findings were retrospectively correlated with five clinical parameters (maximal body temperature, fever duration, leukocytosis, pyuria and admission period) and renal scar development, as seen on follow-up CT (n=12). RESULTS: CT scans demonstrated linear, wedge-shaped, low-density renal parenchymal lesions in 35 kidneys of 25 patients and abscesses in seven kidneys of seven patients, but no abnormal lesions in five patients. In the three groups there was correlation between these findings and some clinical parameters (maximal body temperature, fever duration and admission period), but no subgroup showed significant correlation with any clini-cal parameter. Renal cortical scars detected by follow-up CT were more prevalent in patients in whom initial CT demonstrated the presence of an abscess. CONCLUSION: Clinical parameters correlated with the presence of renal parenchymal hypoenhancing lesions and abscess formation, as seen on CT scans, rather than the number of renal parenchymal lesions. Renal cortical scars were more prevalent in patients in whom initial CT revealed the presence of an abscess. Enhanced CT is thought to be useful both for diagnosing APN and for predicting its clinical course in children.

BACKGROUND: Primary stenting as a direct reperfusion procedure after acute myocardial infarction might reduce recurrent myocardial infarction and target vessel revascularization. However, result of long or multiple stenting in the long or tandem lesions were not known. METHOD: From Jan. 1996 to Dec. 1998, patients with acute myocardial infarction including cardiogenic shock were undergone primary stenting using long or multiple stent. The clinical end points were death, recurrent infarction, subsequent bypass surgery, or repeat angioplasty of the infarct-related vessel. The results were compared with age, sex, lesion, and risk matched standard stenting group. RESULT: Baseline characteristics were similar for the 20 patients who underwent standard length stenting and the 13 patients who underwent long or multiple stenting. Stent diameter was similar in two group (3.4+/-0.3 mm vs. 3.5+/-0.4 mm, p=0.65), but total stent length was longer in long or multiple stenting group (15.5+/-1.8 mm vs. 40.18.4 mm, p=0.01). Average numbers of stent using in multiple stenting were 1.5+/-0.7. Stenting in the infarct-related artery was successful in all patients randomized to stent treatment. At 6 months, the incidence of the primary end point was 25% (5/20) in the standard stent group and 31%(4/13) in the long or multiple stent group (p=0.5). CONCLUSION: Outcomes of long or multiple stenting including mortality, recurrent myocardial infarction and target vessel revascularization was similar to standard stenting. Long or multiple stenting after acute myocardial infarction may possible procedure in some selective cases having long or tandem lesion.

PURPOSE: This was a study on the expiration date of Ethylene Oxide (EO) gas sterilization and effects of the environmental factors of temperature, humidity and type of cabinet in sterile goods storage area on the expiration date. METHODS: Sterile goods storage areas from 13 departments in one hospital were selected and 455 EO gas sterilization samples were prepared and kept in those areas over the 14 months of the study. Each sample was tested with a microbiological culture in the laboratory every week. If the result was positive, the sample was regarded as contaminated. The researcher visited once a month to check the temperature, humidity and type of cabinet. RESULTS: With the exception of 1 sample which was positive at 56th week. 454 samples were confirmed as negative. The environment of the samples storage area was measured monthly. The annual average temperature was 24.2+/-1.6degrees C, and the mean relative humidity 34.7+/-15.2%. The types of cabinet were 7 open and 6 closed. CONCLUSION: The results of the microbiological culture at 13 months showed that none of the samples were contaminated. Therefore the hospital's existing Expiration Date can be extended from 6 months to 13~14 months.

PURPOSE: It was noted some changes of clinical manifestations of mycoplasma pneumonia. we reviewed and compared these changes and saught any clues causes for proper dignosis and treatment. METHODS: We divided patients with mycoplasma pneumonia into two groups, Group 1 (from Jan. to Dec. 1996) and Group 2 (from Jan. to Dec. 1994), and analyzed clinical, radiologic, and serologic differences. RESULTS: Mean age of onset lowered markedly from was 8.34 +/- 2.56 years to 6.91 +/- 3.28 years (P<0.05). In clinical symptoms, high fever lasted longer and gastrointestinal symptoms were more frequent noted group 1. Serologically, high titers of mycoplasma-specific antibody (>1 : 1280) were more frequently observed in group 1 and correlated with severity of clinical manifestations. In radiologic findings, alveolar consolidation were significantly prominent findings in Group (P<0.05). The mean period of response to Roxithromycin was not difference between two groups but longer lasting fever (> or = 3 days) in spite of medication were more prevalent in Group 1 (P<0.05), suggesting increased cases of diminished responsiveness to treatment. CONCLUSIONS: Recently, there was some clinical changes of mycoplasma pneumonia, lowering of onset age, severe clinical symptoms, and more decreased responsiveness to antibiotic treatment. We suggest that it is to neccessary to make some efforts to prevent antibiotics abuse and to decrease the occurrence of resistant strains by introducing of new method for early diagnosis, selective identification of micro-organism and minute sensitivity test for antibiotics.

Intraluminal duodenal diverticulum (IDD) is a rare congenital abnormality, consisting of a sac-like mucosal lesion in the duodenum. Cases of IDD can present with gastrointestinal bleeding, duodenal obstruction, or pancreatitis. Here, we report a rare case of a 25-year-old female presenting with IDD complicated by duodeno-duodenal intussusception and recurrent pancreatitis. The diagnosis was based on findings from radiologic examinations (CT and MRI), upper gastrointestinal series (barium swallow), and gastroduodenofiberscopy. Laparoscopic excision of the presumed duodenal duplication was performed. The subsequent histopathologic evaluation of the excised sac revealed normal mucosa on both sides, but the absence of a proper muscle layer confirmed the diagnosis of IDD. Radiologic detection of a saccular structure in the second portion of the duodenum can indicate IDD with duodeno-duodenal intussusception as the lead point

We investigated the expression of the growth-related nuclear proto-oncogenes, c-fos and c-myc, in early preneoplastic regions and tumor nodules of 3'-MeDAB induced rat hepatocarcinoma. To amplify the levels of these transcripts, we gave cycloheximide (100 mg/kg B.W. i.p.) to each group of rats. The elevated levels of the 2.2 kb c-fos and 2.4 kb c-myc transcripts appeared as early as the 2nd week after feeding on the 3'-MeDAB diet and lasted through the 4th; 6th weeks and tumor. Southern blot analysis indicated that gross amplification or rearrangements were not observed in DNA of the preneoplastic livers and hepatoma nodules. We also measured the rate of the incorporation of [3H] thymidine into hepatic DNA in order to monitor the rate of cell proliferation occurring at the early preneoplastic periods. We have found that the rate of [3H] thymidine incorporation corresponds to the elevated levels of c-fos and c-myc transcripts in the precancerous stages. This finding suggests that the elevated expressions of c-fos and c-myc may result from the continuous cell proliferative stimuli generated in the carcinogen altered cells, which is essential to the initiation and promotion of chemical hepatocarcinogenesis.

Almost all colorectal carcinomas have been thought to develop from pre-existing adenomas. However, some colorectal carcinomas can arise directly from normal flat mucosa, and usually form infiltrative mass at the early stage. The carcinogenesis of this infiltrative carcinoma may be different from the well-known adenoma-carcinoma sequence, which usually forms a polypoid mass. The purpose of this study is to investigate the different expression of various oncogenes in polypoid carcinoma and infiltrative carcinoma. We performed immunohistochemical staining on p53, bcl-2, c-erbB-2 and MIB-1 in 29 polypoid carcinomas arised from adenomas, and 21 infiltrative carcinomas. The average tumor size of infiltrative carcinomas (5.5 cm) was larger than that of polypoid carcinomas (3.1 cm), and the polypoid carcinomas were differentiated more than the infiltrative carcinomas. The results of p53, bcl-2, c-erbB-2, and MIB-1 antisera immunoreactivity in the polypoid carcinoma were 79%, 17%, 21%, and 100%, and those in the infiltrative carcinoma were 71%, 29%, 29%, and 100%, respectively. However the diffuse positivities of p53 and MIB-1 antisera were slightly higher in the infiltraive carcinomas (62%, 76%) than in the polypoid carcinomas (55%, 41%) (p=0.63, 0.01). And the results of p53 and c-erbB-2 immunoreactivity in the adenomas were 52% and 17%, respectively, which is significantly lower than that in the polypoid carcinoma(p=0.03, 0.74). The immunoreactivty of bcl-2 in the adenoma was 72%, which was significantly higher than that in the polypoid carcinoma (17%) (p<0.01). In summary, we did not show the significant difference in expression of p53, bcl-2, c-erbB-2, and MIB-1 proteins between polypoid and infiltrative carcinomas. However, the tendency of infiltrative carcinomas having a more aggressive nature suggests another carcinogenetic mechanism is involved in the colorectal carcinogenesis.
