Flying Publisher I have a dream – A change of generations – Communication channels – Book vs. A medical textbook is available on the internet, accessible for everyone at all times. Even better: it is already on the internet although sales of the print version have not even begun yet. And hard to believe: access on the internet is unrestricted, 800 pages just waiting for readers. In future, the textbook will be updated annually and made available on the internet. HIV Medicine: written by doctors, edited by doctors, published by doctors – for doctors. The advantage: unparalleled dedication from the authors and extremely short production times, which means that there is hardly any other book project in existence where up-to-date medical information is processed as quickly as in HIV Medicine. The continuously updated specialised knowledge which is published in the duo of book + internet becomes a kind of permanent advanced training course, free of charge, prompt and ubiquitous. HIV Medicine 2005 is a so-called Flying Publisher text. Flying Publisher texts exist 1) in book form and 2) simultaneously as a free internet site. So a Flying Publisher text has two physical conditions, a fee-based form (book) and a free-of-charge form (internet). Flying Publisher texts speed up the flow of information. Flying Publisher Just imagine, if there were not only textbooks on HIV and AIDS, but also on other subjects, such as immunology, rheumatology, cardiology, antibiotic therapy, tropical medicine. In an instant, we would have an extensive virtual library with all the relevant information needed for day-to-day use. Would this be a contribution to the improvement of medical care? Secondly, the sceptics – especially if they are not doctors themselves – are not quite in step with the times. In the last five years, the internet has drastically reduced costs and time involved in the production and marketing of information of every kind. Nowadays, doctors can pass on their knowledge directly to colleagues and students, whether by e-mail, PDF files or through their own websites. Doctors no longer have to work together with publishing companies. Until recently, those who published textbooks – mostly 45 and older – were too old to understand the internet. Those, on the other hand, who had some idea of the possibilities offered by the internet were too young and inexperienced, and therefore not ready to write textbooks yet. But, as time passes, people get older and the old ones, too old for the internet, take their leave and the young ones, young enough for the internet, get older and reach the age at which they can write textbooks. In the following chapters, we will work our way step by step through the process of how an idea becomes a text and how we get this text to our readers. The individual stages of this adventure are: 8 Communication Selecting and narrowing down a theme, structuring the material and putting together a team of authors (Page 2) Writing the text and guiding the authors (Page 37) Preparations behind the scenes, while the authors are writing (Page 45) Talks with sponsors (Page 54) Refining and polishing work on the chapters until we have a version ready for press Advance publication of the texts on the internet Advertising and marketing Advertising and marketing Copyright clearance for translation into other languages Before describing these points in detail, we have to go back to basics. What is the difference between books and internet sites? Does it make more sense nowadays to publish a text in a traditional publishing house or as my own publisher? What is the cash flow like in a book project and what cash flows where? Communication Communication is the transportation of thoughts, ideas, wishes, images or visions from one brain to another.

The transducer should be positioned perpendicular 30 | Ultrasound Blocks for the Anterior Abdominal Wall to the anatomical target cheap 2.5 ml xalatan. The transmission gel is an essential tool for the transmission of echoes generic xalatan 2.5 ml mastercard. The transducer and the cable must be covered with a sterile cover. The skin must be disinfected prior to any contact with the transducer and the needle. Focus The focus of the image is usually marked with a point or an arrow at the right side of the screen of the ultrasound device. This arrow should be placed at the same depth of the targeted structure or a bit deeper. Presets Some ultrasound machines offer the possibility to choose between different presets (for muscles, tendons, vessels, soft tissues). Each preset has the best setting of frequency, depth, focus and compound in order to view that tissue. Time-gain Compensation Since echoes reflected from deeper tissues are progressively attenuated, time gain compensation is used to amplify echoes from increasing depths to compensate for their progressive attenuation. Spatial Compound Imaging Modern piezoelectric crystals can produce echoes that travel in many directions and thus return with more information. The contrast resolution is thus enhanced to provide better tissue differentiation, clearer organ borders, and structure margin 2. Ultrasound and Regional Anesthesia | 31 visualization. Tissue layers, nerves and vessels are more clearly differentiated (Figure 2. Ultrasound and the Needle When inserted to perform a block, the needle may be visualized dynamically with the use of either an “in-plane” or “out-of-plane” approach. An in-plane approach is performed when the needle is parallel to the long axis of the transducer (LOX) (Figure 2. An out-of-plane approach is performed when the needle is perpendicular to the long axis of the transducer or parallel to the short axis (SOX). An out-of-plane approach may over- or underestimate the depth of the needle (Marhofer 2010). The needle axis must be parallel and also aligned with the axis of the probe. When injecting, local anesthetic spread must be monitored. If anesthetic spread is not seen, intravascular injection or poor visualization must be excluded. Needle electrostimulators may confirm the presence of the nerve because of the twitching of the muscles caused by the current. However, in abdominal blocks this effect may not occur. One of the problems with needle visualization is that depending on the angle of insertion, some echoes are reflected out of the plane of the transducer and thus lost (Figure 2. The more the needle is parallel to the transducer, the more the echoes will be captured from the transducer and the needle visualized. Equipment Ultrasonography is a safe and effective form of imaging. Over the past two decades, ultrasound equipment has become more compact, of higher quality and less expensive (Figure 2. This improvement has facilitated the growth of point-of-care ultrasonography, that is, ultrasonography performed and 32 | Ultrasound Blocks for the Anterior Abdominal Wall interpreted by the clinician at the bedside. Ultrasounds have been used to guide needle insertion, and a number of approaches to nerves and plexuses (groups of nerves) have been reported. A clear advantage of the technique is that ultrasound produces ”living pictures” or “real-time” images. The identification of neuronal and adjacent anatomical structures (blood vessels, peritoneum, bone, organs) along with the needle is another advantage. Ultrasounds use has been rated as one of the safest practices for patients. The prevention of intravascular injection during regional anesthesia blocks is best accomplished with a combination of ultrasound technique and epinephrine test dosing (Neal 2010). Moreover, anatomical variability may be responsible for block failures, and ultrasound technology enabling direct visualization may overcome this problem. Many studies show that complex nerve plexus block as well as single nerve block techniques can be successfully performed with lower volumes of local anesthetics.

On condition that: your chapters are updated and the literature published up to August 2006 is integrated into the text; the text arrives here by 30th September; the citations are newly compiled and correctly formatted (see below for further details). Original documents The text must only be written in the Word document which we have enclosed here. For the design of the texts see the notes in Free Medical Information (www. Citations In the text, the citation is placed between round brackets, only giving the surname of the first author and the year (Hoffmann 2004). Example: Rockstroh JK, Mudar M, Lichterfeld M, et al.

There are more details in these three lines than you may think: There is no full stop after the initials of first names; several initials are written together. If there are more than 6 authors, the first 3 are named, then comes a comma, followed by “et al” and finished with a full stop. After the title is a full stop (rarely a question or exclamation mark).
