“…Based on previous studies using VITOM, we speculate that the decreased neck strain and fatigue is the result of improved ergonomics throughout the operations that enabled the surgeon to stand straight upright for hours in a comfortable position, thereby decreasing the need to lean or bend the neck to maintain magnifying loupe focus. 10,11 A related aspect that surgeons noted was that although the magnified image quality was thought to be excellent, there was a lack of stereoscopic vision. So in essence, when a surgeon is operating while viewing flat screen images, he or she is viewing a two-dimensional image, very similar to a laparoscope.…”

“…VITOM has been used extensively in neurosurgery and in one study was found to be equivalent to, and a much less expensive substitute for, the traditional operating microscope. 10,11 It has also been used effectively in laryngeal surgery and colposcopy, where less magnification was required. 12,13 The primary goal of this study was to apply the VITOM instrument to complex pediatric surgical and urological procedures and to evaluate it as a potential substitute for loupes.…”

Introduction: Optical magnification is an essential tool in the practice of pediatric surgery. Magnifying loupes are the most frequently used instrument, although their use often comes at the expense of neck pain experienced by the operating surgeon. Recent advances have led to the development of a compact video microscope (VITOM Ò ; Karl Storz Endoscopy GmbH, Tuttlingen, Germany) that displays high-definition magnified images on a flat screen. This study was designed to evaluate VITOM as a potential substitute for loupes in complex open pediatric procedures and to explore VITOM as an effective intraoperative teaching modality for open surgery. Subjects and Methods: Three surgeons used the VITOM II exoscope in 20 operations: 14 hypospadias repairs, 2 inguinal hernia repairs, 1 sacrococcygeal teratoma resection, 1 recurrent tracheoesophageal fistula repair, and 2 additional procedures. Surgeons, trainees, and surgical technicians subjectively evaluated image quality; surgeons evaluated handling of VITOM, degree of neck strain, and fatigue. Three midlevel surgical trainees assessed the VITOM potential for teaching value. Overall impressions of each group and consensus opinions were generated. Results: All procedures were completed without complication. The consensus opinion of the entire group was that image quality was excellent. The surgeons found VITOM easy to use, and all agreed that neck strain and fatigue were reduced. Surgical trainees felt that VITOM imaging aided in their understanding of procedures and anatomy. Surgical technicians perceived improved operation flow through better visualization of the procedure. Conclusions: VITOM provides excellent visualization of pediatric operations with improved surgeon comfort and may serve as a substitute for loupes. Secondarily, we found enhanced trainee learning and potential improvement in the flow of surgical procedures. Further study of VITOM with a larger sample size and validated tools is needed.

“…Der gleiche Versuch wurde zusätzlich mittels des HD-Panoramic-Visualisation-System-HD-PVS (VITOM ® 25, Storz) durchgeführt. Bei der Optik handelt sich um ein starres optisches System mit 10 mm Durchmesser und etwa 80 mm Länge, das mittels einer hochauflösenden HD-Kamera und Kamerakontrolleinheit (Image 1 HD, Storz) das Bild auf einen HD-Monitor mit 16:9-Format (HD WideView, Storz) überträgt [18,19].…”

“…Obesity has been associated with higher levels of serum HGF(Rehman et al , 2003) with concomitant decreases following weight loss(Swierczynski et al , 2005). Higher serum HGF has also been associated with presence of coronary atherosclerosis (Mamelak et al , 2012) and chronic renal disease (Tsien et al , 2009). Furthermore, higher serum concentrations have been associated with myocardial infarction, unstable angina, acute aortic dissection, and pulmonary thromboembolism compared to patients with stable angina (Solivetti et al , 1998).…”

Summary Hepatocyte growth factor (HGF) is a mesenchyme-derived pleiotropic factor that regulates cell growth, motility, mitogenesis, and morphogenesis in a variety of cells, and increased serum levels of HGF have been linked to a number of clinical and subclinical cardiovascular disease phenotypes. However, little is currently known regarding what genetic factors influence HGF levels, despite evidence of substantial genetic contributions to HGF variation. Based upon ethnicity-stratified single-variant association analysis and trans-ethnic meta-analysis of 6201 participants of the Multi-Ethnic Study of Atherosclerosis (MESA), we discovered five statistically significant common and low-frequency variants: HGF missense polymorphism rs5745687 (p.E299K) as well as four variants (rs16844364, rs4690098, rs114303452, rs3748034) within or in proximity to HGFAC. We also identified two significant ethnicity-specific gene-level associations (A1BG in African Americans; FASN in Chinese Americans) based upon low-frequency/rare variants, while meta-analysis of gene-level results identified a significant association for HGFAC. However, identified single-variant associations explained modest proportions of the total trait variation and were not significantly associated with coronary artery calcium or coronary heart disease. Our findings indicate genetic factors influencing circulating HGF levels may be complex and ethnically diverse.
