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).

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.

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.

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.

We report a case of spinal, cerebral and cerebellar embolism that occurred following injection sclerotherapy with n-butyl-2-cyanoacrylate for variceal bleeding. The patient had been diagnosed with alcoholic liver cirrhosis and esophageal variceal bleeding. We performed injection sclerotherapy with n-butyl-2-cyanoacrylate. The patient complained of both leg motor weakness and left arm motor weakness after injection and was diagnosed with spinal, cerebral and cerebellar embolism following the n-butyl-2-cyanoacrylate injection. At the follow-up examination, the patient's neurologic symptoms had improved, but left leg motor weakness remained. To our knowledge, this is the first report of a case of multiple embolizations including the spine, cerebrum and cerebellum after n-butyl-2-cyanoacrylate injection for treatment of esophageal variceal bleeding.

PURPOSE: We aimed to identify microbiological characteristics in patients with acute prostatitis after transrectal prostate biopsy to provide guidance in the review of prevention and treatment protocols. MATERIALS AND METHODS: A retrospective analysis of medical records was performed in 1,814 cases who underwent prostate biopsy at Seoul St. Mary's Hospital and St. Vincent's Hospital over a 5 year period from 2006 to 2011. Cases in which acute prostatitis occurred within 7 days after the biopsy were investigated. Before starting treatment with antibiotics, sample collections were done for culture of urine and blood. Culture and drug susceptibility was identified by use of a method established by the Clinical and Laboratory Standards Institute. RESULTS: A total of 1,814 biopsy procedures were performed in 1,541 patients. For 1,246 patients, the procedure was the first biopsy, whereas for 295 patients it was a repeat biopsy. Twenty-one patients (1.36%) were identified as having acute bacterial prostatitis after the biopsy. Fifteen patients (1.2%) had acute prostatitis after the first biopsy, and 6 patients (2.03%) experienced acute prostatitis after a repeat biopsy. Even though the incidence of acute bacterial prostatitis was higher after repeat biopsy than that after the first biopsy, there was no statistically significant intergroup difference in terms of incidence (chi2=1.223, p=0.269). When the collected urine and blood samples were cultured, Escherichia coli was found in samples from 15 patients (71.4%), Klebsiella pneumoniae in 3 patients (14.3%), Enterobacter intermedius in 1 patient (4.8%), E. aerogenes in 1 patient (4.8%), and Pseudomonas aeruginosa in 1 patient (4.8%). A fluoroquinolone-resistant strain was confirmed in 5 cases (23.8%) in total. Three cases of E. coli and 1 case of Klebsiella had extended-spectrum beta-lactamase activity. CONCLUSIONS: Empirical treatment of acute prostatitis should be done with consideration of geographical prevalence and drug resistance. This study will provide meaningful information for the management of acute prostatitis after transrectal prostate biopsy.
