Early and longterm prognosis depended on the extents of acute myocardial infarction and residual myocardial function. Many clinical methods have been evaluated to determine their ability to estimate the size of myocardial infarcts. But because of many disadvantages simplified QRS scoring system, used with standard 12-lead EKG, was developed, which is noninvasive, inexpensive and easily releatible. Therefore, the correlation between QRS and peak CK,killip classification were evaluated in 55 patients with initial acute myocardial infarction at the Chung-Ang University, Yong-San and Pil-Dong Hospital during the period from January 1983 to December, 1986. The results were as follows : 1) The average QRS score of the anterior wall infarction is 7.1 and that of the inferior wall infarction is 4.5 and there is a statistical significance(p<0.01). 2) In the acute myocardial infarction, the correlation coefficeient between the QRS score and the killip classification is 0.66(p<0.05). 3) In the acute myocardial infarction, the average QRS score is 6.3 and the correlation coefficient between the leak CK and the QRS score is 0.52(p<0.05). 4) In the anterior wall infarction, the average QRS score is 7.1 and the correlation coefficient between the peak Ck and QRS score is 0.48(p<0.05). 5) In the inferior wall infarction, the average QRS score is a 4.5 and the correlation coefficient between the leak CK and QRS score is 0.79(p<0.05).

During a 9-year period 43 children and adolescents 2 to 18 years old underwent 140 extracorporeal shock wave lithotripsy (ESWL) treatments for 48 calculi. The second generation piezoelectric lithotriptor (LT01) was used in 28 cases (65%) while the remaining cases were treated with the third generation piezoelectric lithotriptor (LT02). LT02 lithotriptor differs from an earlier model LT01 in 2 important respects; a stone localization system consisting of ultrasound and fluoroscopy, and more energy per shock wave. The LT01 necessitated caudal anesthesia in 14 cases (50%) while the LT02 necessitated caudal anesthesia in 2 cases (13%) and intravenous anesthesia in 2 cases (13%). Two upper ureteral stones without ureteral dilatation and 1 mid ureteral stone, which were difficult to detect with ultrasound, could be localized by combined ultrasound and fluoroscopy on LT02. The success rate by LT01 and LT02 ESWL was 92.9% and 100%, respectively. The mean session of LT01 and LT02 ESWL was 3.6+/-.4.09 and 2.6+/-2.47, respectively, and the total storage of LT02 ESWL (93+/-97.8) was much less(p<0.05) than that of LT01 ESWL (363+/-380.3). There were no statistical differences in regard to success and the use of stents, stone size or location between the 2 lithotriptors. Six patients required adjuvant procedures, and ESWL complications were not required admission or surgical management. Therefore, LT02 piezoelectric lithotripsy, in comparison with LT01, is more efficient to localize stones and can lessen total storage by reducing treatment sessions in children and adolescents.

PURPOSE: To evaluate the values of C-reactive proteins(CRP) for predicting the severity and results of treatment for acute pyelonephritis in women, we compared the severity of symptoms and signs, the laboratory findings and the initial serum CRP according to the early response to treatment. MATERIALS AND METHODS: We retrospectively analyzed 298 female patients who were diagnosed with acute uncomplicated pyelonephritis between January 2002 and Match 2007. All the medical records were reviewed for a variety of factors, and the baseline characteristics and CRP level were compared between the patients with an early response to treatment and those without according to the 3rd hospital day urine analysis. RESULTS: The initial white blood cell(WBC) counts, the CRP level, the neutrophil ratio and severity of symptoms were significantly higher in the delayed response groups than those in the early response groups. The age, history of previous pyelonephritis, symptom duration, body mass index(BMI), and the number of positive blood and urine cultures were not different between the two groups. According to the results of the multivariate logistic regression analysis, the CRP level, neutrophil ratio and mild symptoms were independent predictive variables that affected the delayed response. The odds ratios(95% CI) were 1.078(1.028-1.131) for the CRP, 1.030(1.001-1.060) for the neutrophil ratio and 9.268(1.072-80.166) for the severe symptoms. The differences between the areas under the ROC curves for CRP and the WBC counts and for the CRP level and neutrophil ratio were statistically significant(p<0.001 and p<0.05, respectively). CONCLUSIONS: We found that the discriminatory power of the initial CRP level was high with regard to predicting an early response. So, we were able to determine a CRP level that would be useful in guiding hospitalization.

Background/Aims: Endoscopic submucosal dissection (ESD) is the first-line treatment for superficial gastrointestinal neoplasms with negligible lymph node metastasis. It has evolved through improvements in expertise and equipment, increased understanding of indications and short- and long-term outcomes, and better management of complications. This study aimed to assess and characterize the most influential publications in ESD research. Materials and Methods: We searched the top 50 most cited articles using Web of Science Core Collection (WoSCC) and Google Scholar (GS) from the inception of these services to January 2019. The top 50 Altmetric Attention Score (AAS) articles based on online media mentions were also searched. Each article was evaluated for the number of citations, title, journal, and publication year. Results: The number of citations for the top 50 WoSCC articles on ESD ranged from 37 to 199; Endoscopy published the most articles (20%). Among the top 50 GS articles, Gastrointestinal Endoscopy published the most ESD articles (34%) and the most shared AAS articles (42.6%). PubMed Central article citations in WoSCC or GS showed significant correlation with those from each metric, unlike AAS. The words with the highest relevance scores were “submucosal tunnel dissection,” “guideline,” “novel submucosal gel,” “adhesive material,” “cell sheet,” “esophageal ulcer,” “hemospray,” and “endoscopic closure,” while the following words were influential: “meta-analysis,” “esophageal stricture,” “perforation,” “bleeding,” “fibrin glue,” “artificial ulcer,” “porcine model” and “esophageal squamous cell neoplasia,” excluding “ESD.” Conclusions This study presents a detailed list of influential articles, journals, and topic words.

OBJECTIVE: Clinical application of Functional Electrical Stimulation (FES) was limited due to the muscle fatigue phenomenon. This study was undertaken to find an electrical stimulation frequency, which optimally improves muscle endurance in spinal cord injured rabbit. METHOD: Fifteen rabbits were experimentally spinal cord injured at the T10 or T11 spinal cord level. Three kinds of stimulation frequency (10, 20, 40 Hz) and sham control stimulation were applied to the tibialis anterior muscle of each four group for 1 hour per day, for 2 weeks. Muscle fatigue index and peak torque were measured during electrical stimulation, and proportion of the type I musclefiber was measured at ATPase (pH 9.4) staining. RESULTS: Complete paraplegia was obtained in all 12 rabbits. Muscle fatigue index and peak torque were not changed after 2 weeks of electrical stimulation in all four groups. The proportion of the type I muscle fiber was reduced in all four groups after 2 weeks. However, 40 Hz stimulation group showed less decline in proportion of type I muscle fiber than control or 10 Hz group. CONCLUSION: High frequency electrical stimulation applied at an early stage of spinal cord injury is more effective in preserving muscle endurance than low frequency stimulation.

Although spontaneous bacterial peritonitis is a frequent complication in the childhood nephrotic syndrome, it is very rare in adults with nephrotic syndrome. It frequently develops when the patients are either in relapse or receiving steroid therapy at the time peritonitis is diagnosed. We report an unusual case of a spontaneous bacterial peritonitis as the presenting feature in a 15-year-old male patient with nephrotic syndrome. He presented with diffuse abdominal pain and distension for 15 days. Abdominal paracentesis revealed the diagnostic laboratory findings of peritonitis, and the bacterial culture of the ascites showed a mixed growth of Escherichia coli and Pseudomonas aeruzinosa. His serum albu- min level was 1.6gldL and the amount of 24 hours proteinuria was 21.0g/day. Although he was treated with adequate antibiotics for 3 weeks, the peritonitis was more aggravated. We decided to insert a catheter into the peritoneal cavity for continuous drainage of the intractable ascites. Two weeks after drainage, the peritonitis improved as the peritonitis subsided, the proteinuria disappeared completely without a steroid therapy. Six months after spontaneous remission, the proteinuria have recurred, and the kidney biopsy then showed focal segmental glomerulorsclerosis.

PURPOSE: The purpose of this study was conducted to evaluate the clinical results of proximal tibial plateau fractures treated with open reduction and internal fixation through the lateral submeniscal approach and allowed early motion of the knee and to evaluate the effectiveness of the approach. MATERIALS AND METHODS: From January 1998 to December 2002, fifty four patients who underwent open reduction through the lateral submeniscal approach for proximal tibia plateau fracture and had a follow-up more than one year were included in this study. Clinical results were evaluated by postoperative radiographs taken at the last follow-up and Porter's assessment method. RESULTS: Anatomical reduction was achieved under direct vision through the submeniscal approach in most of the cases in this study. The postoperative radiographs showed anatomical reduction in 32 cases (59%) and adequate reduction with displacement within 2 mm in 20 cases (37%). The clinical evaluation by Porter's assessment method revealed that 49 cases (91%) were acceptable results of excellent or good at the final follow-up CONCLUSION: This study indicates that open reduction and internal fixation through the lateral submeniscal approach can be a good option for proximal tibia plateau fractures because it allows accurate reduction of the articular fractures, which is confirmed directly during operation, identification and repair of associated soft tissue injuries are facilitated, sufficient bone graft and stable fixation of the articular fragments under direct vision allow early motion of the knee.
