This book was released on 2013-12-11 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: In conventional partial resection of parenchymatous organs significant bleeding is one of the main problems, especially in neonates and infants. The patients rapidly lose considerable amounts of their small blood volume. Laser light leads to photo thermal effects in tissue and causes coagulation, drying up, carbonization and evaporization, depending on the temperature. The neodymium Y AG laser emits nonvisible light in the near infrared with a wavelength of l. 0611m. This wavelength implies a relatively deep penetration into the tissue. This laser system, properly a coagulation laser, achieves its cutting effect by its high power density [9]. Because of thermal radiation in all directions, both sides of the section plane are coagulated as a positive side effect. Thus, in parenchymatous organs a combination of resection and sealing of the cut vessels and ducts, up to a limited diameter, is obtained. Laser Instruments We use a neodymium-YAG laser mediLas 2 (MBB-Medizintechnik, D-8012 Ottobrunn, Federal Republic of Germany), wavelength l. 0611m, maximal power output around 110 W (Fig. 1). Normally we prefer to work without tissue contact, Fig. l.

Book Synopsis Procedures in Hepatogastroenterology by : G.N. Tytgat
Download or read book Procedures in Hepatogastroenterology written by G.N. Tytgat and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Endoscopy has revolutionized clinical gastroenterology. In 1961 Basil Hirschowitz published the first flexible endoscopic examination of the stomach and duodenal bulb. We moved from flexible fiberendoscopes to current video-endoscopic equip ment. Current video-endoscopes incorporate a black and white or color 'chip' at the tip of the instrument which transforms the visual image into electronic signals. The size of the pincet is constantly getting smaller, heading for 5 /Lm, further increasing the resolution. The signals are reassembled into high-quality color images in a video monitor. Endoscopes are now used to examine the entire gastrointestinal tract from esophagus to rectum, including the biliary and pancreatic ductal system. Targeted endoscopic biopsy offers rapid and precise diagnosis. Endoscopic ultrasonography is of unsurpassed accuracy in staging gastrointestinal tumors, in assessing pancreatic and biliary disease, and disorders of the rectum and anal canal. Moreover, targeted cytological sampling is possible of abnormalities of the intestinal wall or peri intestinal lymph node. Yet despite these glamorous achievements changes are to be expected in the overall emphasis of diagnostic endoscopy. Magnetic resonance cholangiopancreatography may very well compete for a substantial fraction of diagnostic ERCP. Virtual colonoscopy or computed tomographic colography may well compete with (and take over?) screening/surveillance colonoscopy.

Book Synopsis Nonlinear Optical Cavity Dynamics by : Philippe Grelu
Download or read book Nonlinear Optical Cavity Dynamics written by Philippe Grelu and published by John Wiley & Sons. This book was released on 2015-12-23 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: By recirculating light in a nonlinear propagation medium, the nonlinear optical cavity allows for countless options of light transformation and manipulation. In passive media, optical bistability and frequency conversion are central figures. In active media, laser light can be generated with versatile underlying dynamics. Emphasizing on ultrafast dynamics, the vital arena for the information technology, the soliton is a common conceptual keyword, thriving into its modern developments with the closely related denominations of dissipative solitons and cavity solitons. Recent technological breakthroughs in optical cavities, from micro-resonators to ultra-long fiber cavities, have entitled the exploration of nonlinear optical dynamics over unprecedented spatial and temporal orders of magnitude. By gathering key contributions by renowned experts, this book aims at bridging the gap between recent research topics with a view to foster cross-fertilization between research areas and stimulating creative optical engineering design.
Book Synopsis Medical Laser Endoscopy by : D.M. Jensen
Download or read book Medical Laser Endoscopy written by D.M. Jensen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been incredible progress over the last decade in therapeutic endoscopy. Such therapies are either easier now than ten years ago or are possible when previously they were inconceivable. These advances have depended upon major improvements in diagnostic endoscopy for different subspecialties. Simultaneously, a major innovation for therapeutics through endoscopes is the application of medical lasers. This book is written by renowned biophysicists and laser endoscopists of different sub specialties where the application of lasers has revolutionized medical care. In some cases treatments which were not previously possible are now routine. Laser palliation of obstructing tumors in different sub specialties is an example of this. In other cases, resective surgery is obviated by the application of lasers via endoscopy such as for the control of gastrointestinal bleeding. The authors of different medical or surgical subspecialties which use endoscopic lasers write about the pathology and clinical problems, their personal experience and results. However, they also emphasize their techniques of laser endoscopy through case examples, technical discussions, and colored illustrations. Their discussions will give the reader a better understanding about the role of laser treatment of different conditions compared to routine medical or surgical therapy. In several instances, randomized controlled trials involving medical lasers were discussed in this book because they fundamentally changed our understanding of common problems such as upper gastrointestinal bleeding. We predict continued progress in therapeutic endoscopy.

Book Synopsis Atlas of Lasers and Lights in Dermatology by : Giovanni Cannarozzo
Download or read book Atlas of Lasers and Lights in Dermatology written by Giovanni Cannarozzo and published by Springer Nature. This book was released on 2020-02-25 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: This richly illustrated atlas written by a team of experts guides the reader to the applications of lasers and light technologies in dermatology. It is divided in two parts: the first reviews the physical and optical concepts related to lasers and light sources, and provides a detailed description of surgical (ablative and non-ablative), vascular and pigmentary laser devices. It also discusses difficult-to-treat conditions, such as melasma and scars. The second part of the atlas is more clinically-oriented, presenting reproducible parameters and high-resolution images of pre and post-treatment, and desired end points in order to achieve an optimal result. Enabling readers to gain an understanding of the various topics concerning lasers, it explores conventional, non-conventional and combined laser treatments in a wide range of indications, as well as practical aspects such as medicolegal issues, informed consent and management of complications. The increasing knowledge and growing expertise in lasers and light devices make it necessary for physicians to be aware of the latest developments in this quickly evolving field. As such, this book is of interest to all physicians working in dermatology, cosmetology and aesthetic medicine, as well as to physician assistants and nurses using lasers in their daily practice.
Book Synopsis Principles and Practice of Lasers in Otorhinolaryngology and Head and Neck Surgery by : V. Oswal
Download or read book Principles and Practice of Lasers in Otorhinolaryngology and Head and Neck Surgery written by V. Oswal and published by Kugler Publications. This book was released on 2014-01-24 with total page 951 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foreword In this era's informational paradigm, while pondering the considerations to be penned in this foreword, the relevance of a text such as this emerged progressively as the focal point. After all, for years, one established source for accessing large amounts of valuable information had been the Encyclopaedia Britannica, a printed tome, which is no longer relevant. Instant access to the latest scientific information is freely available to all with an internet. So, what can this text provide that cannot be readily accessed? In contemplating given topics, the Editors, as most certainly occurred in this publication, chose clinical authorities to author chapters in their areas of expertise. The experienced clinician often finds such a forum a unique opportunity to reflect on years of knowledge acquisition and then render an insightful discourse on the lineage of his/her current understanding of the topic. On the other side of the coin, the reader instantly acquires a knowledge base, which was validated with an exhaustive literature search and gains the senior authors' perspective of it. A less experienced author will benefit from thoroughly reviewing the currently available science and technology and moreover, gain experience in scientific writing. In the latter scenario the senior author is at once mentor and expert. Under ordinary circumstances, from the concept outline submission to a publisher, the time line to completion of the text is approximately one and a half to two years. Recruiting and assigning authors, awaiting late manuscript submissions and editing are unquestionably time consuming. Yet a passionate, dedicated Editor will take seemingly varied submissions and script them into a worthy finished product. Such was the case with this publication. The end result is a superbly structured text covering most of the concepts relating to the topic in a format that is both logical and intuitive. At the risk of some redundancy, I share with you my thoughts on some of the significant number of new additions and improvements made to this second edition. The chapter on risk management is a welcome contribution. The rationale for the shift in the current decision tree for laryngeal cancer as it relates to macro versus micro margins, improvements in voice quality and the choice of initial therapeutic considerations are appropriately vetted. The rethinking of HPV associated malignancies is a new and most important addition. Zeitels' presentation of angiolytic lasers for benign and malignant pathology is state of the art. I particularly enjoyed reading about lasers and the association with tropical diseases. The chapters on robotic surgery, non-invasive cartilage reshaping and photo-diagnostics puts the latest technical innovation in our discipline into perspective. The excellent illustrations and photographs are a bonus. There are other areas that could be mentioned e.g. paediatrics, however, the aforementioned has more than adequately established the tenor of the text. n their quest to provide a one-stop knowledge base of a reference quality, it is inescapable that the size of the final proof would surpass the typical numbers of between four and five hundred pages for the hard bound volume. Tightening the text by removing some peripheral material would deprive the book its very objective of a reference quality publication. The obvious solution was to present the work in a set of two volumes, and the editors and the publishers have to be congratulated in achieving this seamlessly. The natural anatomical split provides the reader with a convenience of picking up the volume of relevance for the task at hand. An unusual feature is the inclusion of MCQs after each chapter, to serve as a test for recall of knowledge, the result of which can be assessed simply by going back to the chapter! The Editors and the publishers have exploited the now ubiquitous electronic media network to their advantage. Operating on various platforms a dedicated website will complement the book with updates, operative videos, and means of communication to share the knowledge globally. It was the focus of this brief foreword to explore the relevance of this text in the current informational climate. It provides the essential foundation for informed thought on this topic. Agree or disagree with the information contained within, the reader has acquired the knowledge to be able to do such. With this text you will be rewarded for sitting in your most comfortable chair, thumbing through the pages and sensing the new print. Immediately understood will be the time and effort it took to complete a text of this calibre. Read the chapters first that initially appeal to you and then without question you will read the remainder. This book should be in the library of any serious student of the subject. I feel privileged to have been asked to write the foreword. Marshall Strome

Book Synopsis Advances in Nd:YAG Laser Surgery by : Stephen N. Joffe
Download or read book Advances in Nd:YAG Laser Surgery written by Stephen N. Joffe and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Nd:YAG laser has finally become the multidisciplinary and muitispeciaity tool of the 1980s. Primarily developed for gastrointestinal applications for controlling bleeding, at present it is also used for endoscopic treatment of gastrointestinal tumors, endobronchial cancer, and bladder and gynecological lesions and finding applications in otorhinolaryngology and neurosurgery. De velopment of laser scalpels and focusing head-pieces has now allowed the Nd:YAG laser to be used for open surgical procedures in general and plastic surgery, head and neck surgery, urology, gynecology, dermatology, and neu rosurgery. The rapid development in ceramic technology has led to contact surgery allowing physicians a choice of excision, vaporization, coagulation, incision, or combinations thereof by easily changing probes rather than having to select new laser wavelengths. This technology is rapidly replacing the carbon dioxide laser which currently has no adequate flexible waveguide for fiberoptic en doscopy, cannot be used in a water medium (e.g., bladder), and has poor coagulation properties when compared to the Nd:YAG laser. Future developments may see the Nd:YAG laser even replacing electro cautery in the operating room due to its greater safety and efficacy. Local hyperthermia (laserthermia) with computer control, photodynamic therapy, and ophthalmic applications make the Nd:YAG laser the most exciting tech nological advancement in medicine and surgery for the 1980s.
Book Synopsis The Evaluation of Materials and Structures by Quantitative Ultrasonics by : J.D. Achenbach
Download or read book The Evaluation of Materials and Structures by Quantitative Ultrasonics written by J.D. Achenbach and published by Springer. This book was released on 2014-05-04 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nondestructive evaluation (NDE) procedures are needed for materials processing, as well as for post-process materials testing. They play important roles in product design, analysis of service-life expectancy, manufacturing and quality control of manufactured products. They are also essential to on-line monitoring of the integrity of structural elements and complex systems. Rational accept and reject criteria should be based on NDE tests. Critical safety, efficiency and operational features of large-scale structures depend on adequate NDE capabilities. The lectures presented in this volume are concerned with quantitative ultrasonic NDE. They present fundamental concepts and basic theory, as well as applications to the detection of cracks and the evaluation of material properties. The following topics are discussed: basic wave propagation theory for ultrasonic NDE; piezoelectric transducers, EMATS and ultrasonic spectroscopy; laser-based ultrasonics; acoustoelasticity; ultrasound in solids with porosity, microcracking and polycrystalline structuring; the determination of mechanical properties of composite materials; inverse problems and imaging.
