1.New Technologies for Magnetic Resonance Imaging Compatible Device of Boston Scientific.
International Journal of Arrhythmia 2016;17(3):150-155
The use of both magnetic resonance imaging (MRI) and pacing devices has vastly increased worldwide in recent years. A significant number of implanted patients will likely need monitoring using magnetic resonance imaging (MRI) over the course of the lifetime of their device. Some studies have demonstrated that with appropriate precautions, MRI can be safely performed in patients with selected implantable pacemakers. However, MRI is still contraindicated in patients with pacemakers. Recently, new pacing systems have been specifically designed for safe use in the MRI environment. The first reported experience suggests that the technology is safe and may allow patients with these new pacemakers to undergo MRI. This review will describe the outstanding issues and controversies surrounding the safety of MRI in patients with pacemakers, and the potential benefits of the new MRI-conditional technology. We will also discuss how to decide whether an MRI-conditional system should be implanted, and highlight key issues that warrant further studies.

OBJECTIVE: We investigated the expression of uPA and uPAR in eutopic endometrium of advanced stage endometriosis and control patients. METHODS: The 33 endometriosis patients and 32 controls were enrolled. Endometrial samples were obtained from 65 premenopausal women aged 29~44 years, undergoing laparoscopic surgery or hysterectomy for non-malignant lesions. Sufficient samples were collected from 33 patients with endometriosis stage III and IV and 32 controls without endometriosis confirmed by laparoscopic surgery. The mRNA expression of uPA and uPAR from eutopic endometrium were analyzed by RT-QC PCR. RESULTS: The mRNAs of uPA and uPAR were expressed in eutopic endometrium from endometriosis and normal controls throughout the menstrual cycle. Uterine endometrium from women with endometriosis expresses significantly (p<0.05) higher levels of u-PA mRNA than endometrium from normal women without endometriosis in the proliferative phase. There were no significant differences in expression of uPAR in eutopic endometrium between controls and endometriosis patients. CONCLUSION: These results suggest that eutopic endometrium from endometriosis patients may be more invasive and prone to peritoneal implantation because of greater u-PA mRNA expression than endometrium from women without endometriosis. Thus, increased proteolytic activity may be one etiology for the invasive properties of the endometrium resulting in the development of endometriosis.

Aortic stenosis is the most frequent type of valvular heart disease in adult. Approximately 2-7% of the population over the age of 65 suffer from aortic valve stenosis. Due to the increasing average life expectancy in Korea, degenerative aortic stenosis is increasing and becoming a troublesome health problem in older population. Because older patients with severe degenerative aortic stenosis have many other medical conditions so they are not suitable candidate for surgery. Recently, transcatheter aortic-valve implantation (TAVI) has been suggested as a less invasive treatment for patients with high perioperative risk. We report a successful TAVI case in severe aortic stenosis patient with high perioperative risk.

PURPOSE: Dysregulation of gastric epithelial cell proliferation and apoptosis are important in development of ulcer, atrophy and neoplasia in Helicobacter pylori (H. pylori) infection. The aim of this study was to investigate the effect of infection of H. pylori on gastric epithelial cell proliferation and apoptosis in children. METHODS: Histological grading by updated Sydney system, PCNA immunostaining and TUNEL method were performed in H. pylori positive (N=58) and negative (N=40) gastric biopsy specimens. RESULTS: In H. pylori positive children, there were significantly higher grade of polymorphonuclear neutrophil activity (P=0.000), chronic inflammation (P=0.000), epithelial damage (P=0.000) and lymphoid follicles (P=0.000) than in H. pylori negative children. Intestinal metaplasia was not seen in H. pylori positive children. PCNA index was significantly different between H. pylori positive children (67.8+/-18.13) and H. pylori negative children (54.8+/-14.46, P=0.000). There was positive correlation between PCNA index and H. pylori density (r=0.277, P=0.007), polymorphonuclear neutrophil activity (r=0.280, P=0.007) and chronic inflammation (r=0.284, P=0.006). Apoptosis index of H. pylori positive children (0.44+/-0.447) was significantly higher than of H. pylori negative children (0.14+/-0.196, P=0.000). There was positive correlation between apoptosis index and H. pylori density (r=0.472, P=0.000), polymorphonuclear neutrophil activity (r=0.370, P=0.001) and chronic inflammation (r=0.483, P=0.000). There was positive correlation between PCNA index and apoptosis index (r=0.353, P=0.003). CONCLUSION: The PCNA and apoptosis index in H. pylori positive children were significantly higher than in H. pylori negative children. This study suggested that gastric epithelial cell proliferation and apoptosis are important to pathogenesis of H. pylori infection in children.

PURPOSE: The usual technique of temporomandibular joint (TMJ) reduction, recommended by most emergency medicine textbooks, consists of downward forces applied to the mandible. However, it has been the authors' experience that conscious sedation and significant force is required to achieve reduction. For that reason, we designed a new method of TMJ reduction. The purpose of our study is to introduce the new method of TMJ reduction and to compare the traditional method with the new method. METHODS: We performed a prospective, randomized trial with 52 patients who were diagnosed as having a TMJ dislocation. The patients were divided into two groups: the group treated with the traditional method (25 cases) and treated with the new method (27cases). Patients with histories of trauma or inflammatory signs were excluded from this study. The new method is an extraoral approach in which the operator applies the coronoid process on the face in the posteroinferior direction. RESULTS: Age, sex, and history of TMJ dislocation showed no statistical differences between the two groups. Reduction of the TMJ dislocation was achieved in 15 (60.0%) of the traditional method group and in 25 (92.6%) of the new method group (p=0.005). The means of the reduction time were 11.8+/-6.2 sec in the traditional method group and 6.6 +/- 3.3 sec in the new method group (p=0.007). CONCLUSION: The new method was an effective treatment for TMJ dislocation without any sedations. I had a higher success rate and a shorter reduction time than traditional method.
