PRESENTING YOUR WORK 269 Summary Points ° Manuscripts must be typed or printed on one side of A4 paper. It is not meant to be a definitive account, and the reader is advised to refer to the relevant legislation. Always seek legal advice if you are in any doubt about copy right or contractual matters. The Copyright, Designs and Patents Act of 1988 provides, amongst other things, protection for original literary works and the typographical ar rangements of published editions. It is useful for authors to note that copyright applies to the form in which ideas are expressed, and not to the ideas themselves. Copyright does not subsist in the literary work until it is recorded in writing or other simi lar means. However, if the author has completed the work as part of his or her duties as an employee, then the employer has ownership. The author may also assign copyright to the publisher, a com mon practice when work is published in journals. In these cases authors who try to resell an article, without the permission of the journal’s pub lisher, will infringe copyright law. In the United Kingdom, copyright is usually the life of the author plus 70 years. Copyright for the typographical arrangement of a published edition expires at the end of 25 years. However, there are variations in copyright, 270 PROTECTING YOUR RIGHTS 271 especially between countries, so never assume that copyright has expired. You need to get permission to reproduce original or adapted versions of the following: 1. Illustrations such as photographs, figures, drawings, graphs and tables. Single quotations of more than 300 words or several quotations from the same source that are equivalent to more than 300 words (Churchill Livingstone 1996). However, it should be noted that the Act states that ‘substantial parts of the work’ are measured in terms of quality and not quantity, so use the above word limit with caution. Seek the advice of your publisher or contact the copyright owner if you are unsure. You will need to acknowledge the original source of any copyrighted material you use in your own work. Indicate the granting of permission within the text of your work, for example, ‘Reproduced with the kind per mission of…’. Write to the copyright holder to obtain written permission for using mate rial. Give precise details of what you want to copy, for example the title of the work and the page and line numbers.

This syndrome is caused by lacunar (small deep) infarction in the contralateral basis pons at the junction of the upper third and lower two-thirds. It may also be seen with infarcts in the contralateral thala- mocapsular region, posterior limb of the internal capsule (anterior choroidal artery syndrome), red nucleus, and the paracentral region (anterior cerebral artery territory). Sensory loss is an indicator of cap- sular involvement; pain in the absence of other sensory features of thalamic involvement.

Athetosis often coex- ists with the more flowing, dance-like movements of chorea, in which case the movement disorder may be described as choreoathetosis.

The term is often applied to wasted muscles, usually in the context of lower motor neurone pathology (in which case it may be synonymous with amyotrophy), but also with disuse. Atrophy develops more quickly after lower, as opposed to upper, motor neurone lesions. It may also be applied to other tissues, such as subcutaneous tissue (as in hemifacial atrophy). Atrophy may sometimes be remote from the affected part of the neu- raxis, hence a false-localizing sign, for example wasting of intrinsic hand muscles with foramen magnum lesions.

It is generally accepted that attention is effortful, selective, and closely linked to intention. Impairment of attentional mechanisms may lead to distractibility (with a resulting complaint of poor memory, better termed aprosexia, - 44 - Auditory Agnosia A q. The neuroanatomical substrates of attention encompass the ascending reticular activating system of the brainstem, the thalamus, and the prefrontal (multimodal association) cerebral cortex (especially on the right). Those adapted to “bedside” use all essentially look for a defect in selective attention, also known as working memory or short term memory (although this does not necessarily equate with lay use of the term “short term memory”): Orientation in time/place Digit span forwards/backward Reciting months of the year backward, counting back from 30 to 1 Serial sevens (serial subtraction of 7 from 100, = 93, 86, 79, 72, 65).

Auras are exclusively subjective, and may be entirely sensory, such as the fortification spectra (teichop- sia) of migraine, or more complex, labeled psychosensory or experien- tial, as in certain seizures.

Palpation of the medial joint line for tenderness compatible with a meniscal injury buy anafranil 10mg overnight delivery depression for teens. The McMurray test is performed by fully ﬂexing the knee and rotating the tibia as the knee is slowly extended (Fig order discount anafranil on-line bipolar depression 75. A positive test is painful with full ﬂexion and rotation; a clunk or snap is heard or felt when the knee is extended cheap anafranil 25mg on-line depression worse in morning. The medial tear is elicited initially with the internal rotation followed by the external rotation during extension. This rotation of the tibial plateau will catch the posterior horn of the meniscus between the tibia and femoral condyle, producing a clunk and causing pain. The meniscus tugging on the pain-sensitive synovium at its peripheral attachments produces the pain. The test is notoriously inaccurate, and in most situ- ations the pain with full ﬂexion and rotation is sufﬁcient to conﬁrm an injury to the meniscus. The mechanism of the popping with the McMurray test is demon- strated in the video on the CD. It shows the tibial plateau subluxing forward and trapping the posterior horn of the meniscus between the femur and the tibia. It also illustrates why the unstable knee has a high incidence of meniscal tears. Collateral Ligament Assessment The collateral ligaments are assessed by varus and valgus stress testing at 0° and 30° (Fig. Valgus stress is applied to the knee to test the medial collateral ligament. Grade 2 has laxity with an end- point, and grade 3 is gross laxity at both 0° and 30°. The site of tender- ness on the ligament can determine the site of injury (i. The examination of the collaterals is important to determine whether the ACL injury is isolated. Anterior Drawer Test This test is generally not useful for detecting injury in the acute situa- tion (Fig. Do not confuse the anterior motion with the knee that is posteriorly subluxed and the anterior motion of pulling the knee to the neutral position. In the anterior drawer test, the ACL is stressed by pulling the tibia anteriorly at 90° of ﬂexion. When the quadri- ceps is contracted against resistance with the knee ﬂexed at 30° and without weight bearing, there is an anterior displacement of the tibia (this is an open kinetic chain exercise). Open kinetic chain exercise is also seen with the patient on the quadriceps machine in a ﬁtness room. The quadriceps pulls the tibia forward if there is no ACL or causes signiﬁcant strain on the ACL graft. In the early rehabilitation phase, this exercise must be avoided to prevent strain on the recently implanted graft. Associated Ligament Injuries It is always important to perform a posterior drawer test (Fig. If this is done routinely, you will not miss a posterior cruciate ligament 22 2. The external rotation of the tibia must be measured at both 90° and 30° to rule out associated injury to the posterolateral corner. Imaging Plain Radiographs The screening examination should be a simple anteroposterior and lateral radiograph of the knee. This will reveal open growth plates,ACL bony avulsions, signiﬁcant osteochondral fractures, tibial plateau frac- tures, or epiphyseal fractures. Tomograms If the radiograph is negative, but considerable bony tenderness exists, then tomograms should be done to rule out plateau fractures. Computed Tomography Scan The 3-D scan can help plan treatment for associated tibial plateau fractures. Examination Under Anesthesia and Arthroscopy 23 Bone Scan If the pain persists, this scan may conﬁrm occult bony injury.
A successful synthesis of a new molecule would not make hundreds or thousands of copies of the molecules cheap anafranil 50 mg on line mood disorder jesse jackson, but mil- lions of millions of millions buy anafranil 10 mg visa anxiety 9 code. In order to make a complex molecule discount anafranil express mood disorders young adults, it is necessary to have methods which join simpler molecules together, and also techniques to make small changes to different bits of the molecule, once the framework has been con- structed. There is an enormous variety of reagents which can be used to transform one arrangement of atoms into another. The line drawings at the top show the same molecules as the ball and stick representations below. In the lower version, hydrogen atoms are white, carbon atoms are dark grey, and oxygen atoms are speckled. In the more concise representation at the top, hydrogen atoms attached to carbon are omitted, and the carbon–oxygen double bond in the ketone is drawn with a double line. The lower diagram shows the two hydrogens which must be removed to turn the alcohol into the ketone. One of these is on the oxygen, and the other on the central carbon atom. Many reagents are available which will transform an alcohol into a ketone, removing these two hydrogens and turning the carbon–oxygen single bond into a double bond. It is a problem if the same transformation is used to make a more complicated molecule, such as PM-toxin (Figure 3. This molecule, which is produced by the fungal pathogen Phyllosticta maydis, has been the cause of major epidemics of leaf blight disease in the United States. The top representation is much more concise, but does not give information about the shape of the molecule. The lower illustration shows how the atoms are arranged in space as well as how they are connected to each other. This molecule has four alcohol groups (an oxygen joined to a carbon atom and a hydrogen atom by single bonds). Changing one of these to a ketone (an oxygen joined to a carbon by a double bond) without affecting the others will be difﬁcult, as all the reagents which can do this are likely to act on the whole molecule, not just on a speciﬁc part of it. A synthesis could not ﬁnish by oxidising just some of the alcohols to ketones, because the reagent would not know which alcohols should be oxidised and which should not. How is it possible to selectively make ketones in the presence of alcohols? More generally, how can a trans- formation be made to act on only a part of a molecule? Selective reagents could be developed, so that it is possible to change some alcohols into ketones without affecting others in the same molecule. For example, the lower left hand ketone in PM-toxin is close to the end of the carbon chain. Might it be possible to develop a reagent that only oxidises alcohols which are close to the end of carbon chains? An approach of this sort would require a very good knowledge of the properties of reagents. The molecule could be joined together in such a way that the question does not arise, because the alcohols and ketones are already in the right places as a result of the choice of joining processes. In practice, a combination of these methods may be required in order to make complex molecules. As a result, organic synthesis is an extremely demanding discipline, requiring both a wide knowledge of chemistry and also the ability to develop complete strategies for the construction of molecules. If the last step of a synthesis does not work, then it may be necessary to begin again by altering the ﬁrst step. The science ﬁction character, Dr Who, has machines which can synthesise molecules, just given the target structure. The physical manipulations of mixing and purifying compounds can be automated to a large extent, and it is possible to imagine building a machine which could do the mechani- cal tasks of a highly trained synthetic chemist, although it would be far more expensive and probably less effective than a skilled individual. The main difﬁculty in the construction of such a machine would be to provide the machine with suitable instructions for the synthesis.
