Good reviewers do not send positive messages to authors and leave the editor to break the bad news that the paper is not going to be published quality 250mg antabuse medicine rap song. It is a good feeling when authors make the changes requested and reviewers can write feedback such as The revisions that the authors have made have improved this paper considerably generic 250 mg antabuse free shipping medications medicaid covers. The analyses are logical for answering the study aims purchase 250 mg antabuse otc medicine for the people, the limitations of the study are discussed, and the conclusions are a reasonable interpretation of the results presented. This is confirmation that writing and reviewing are complementary processes that promote the publication of high quality scientific papers. This needs to be included and the authors need to present some data to verify the representativeness of their sample. A sensitivity analysis to allow the reader to gauge the effects of selection bias on the prevalence rates reported would be helpful. Many subgroup analyses are presented, although the small numbers in some groups and the wide confidence intervals indicate a lack of statistical power to test the relationships. The subgroup analyses should preferably be deleted or the authors need to discuss the extent to which the results presented could be type II errors. The tables are long and present far too much data to be readily understood. Many outcome variables are presented, which must overlap to a great extent in individuals. The data would be better summarised into exclusive groups that are categorised according to the multiplicity or severity of symptoms. This would give readers a much clearer idea of the burden of illness in the population studied. The analyses have been stratified by gender although there is no a priori reason to suggest a gender difference and the rates of illness appear similar between the genders. Gender effects would be better tested in a single model unstratified analysis, and this would have the additional benefit of improving precision around the estimates of effect. I can find no evidence in the results to support the conclusion that adenoidectomy may influence immune development. This conclusion seems to be speculative and therefore should be removed. Becoming an editor When I asked him [David Sharp, former Lancet editor] what he had enjoyed most during his Lancet years, he replied “The craft of editing” … David’s love, for it was that, of our craft inspired colleagues over several decades. Richard Horton21 Editors are appointed by the journal’s financial owners. The journal’s owners, who are responsible for making business decisions, may be concerned about many performance indicators of their journal such as circulation rates, 143 Scientific Writing advertisements placed, negative and positive feedback from readers, the number of papers submitted, the number of mentions in the press, and so on. Journals naturally select editors who can maintain or improve these indicators. Because editorial independence is valued highly by both readers and subscribers, the hiring and firing of editors is sometimes debated publicly because it raises questions about editorial freedom, the cultures of journals, and the relationship between a journal and its owners. Editors have full authority for determining the content of the journal and for pleasing the target readership. Readers not only want short articles that are easy to read but they must feel confident that the articles are accurate, informative, and up to date. It is the job of the editor to entice potential readers of the journal to pick it up, open it, start reading, keep reading, and, even better, look forward to the next issue. It is the editor’s responsibility to select reviewers carefully, to ensure that their comments are polite and constructive, to rank areas of priority for publication, and to answer specific questions from authors. Following feedback from reviewers and responses from the authors, the editor has the task of trying to balance the two sources of comments, and adjudicate the final decision about publication. This is sometimes difficult when two of the external reviewers have opposing opinions and, ultimately, the editor has to take responsibility for accepting or disregarding reviewers’ comments. When decisions become especially difficult, the editor may refer the paper to an independent advisory committee who considers issues that are contentious or perceived as malpractice. It takes a long time for journals to establish their reputations and to increase their impact factors and it is the editor’s job to maintain or improve these. An editor is sometimes selected on the basis of the reviews that they have undertaken for a journal. Some journals require that potential editors have performed a certain number of reviews each year to establish commitment before they can become involved in the editorial process. Other journals select editors on the basis of their reputation or through an election process. If you want to 144 Review and editorial processes become an editor, it is probably best to ask a senior colleague for advice about how to get there.

With practice, this discipline helps you learn how to craft your writing to suit your target audience. Irina Dunn1 The objectives of this chapter are to understand how to: • avoid duplicate publication • share data in large research teams • use the electronic media appropriately • assess the merit of journals and journal articles Duplicate publication A scientific paper is (1) the first publication of original research results, (2) in a form whereby peers of the author can repeat the experiments and test the conclusions, and (3) in a journal or other source document readily available with the scientific community. Infection and Immunity2 Redundant or duplicate publication occurs when results that are published in one paper substantially overlap with results published in another. Duplicate publication is unnecessary and is usually fraudulent since the authors have given a signed assurance that their work has not been published elsewhere. If you have any related information that is published in or has been submitted to another journal then you should include it when you submit your paper. In this way, it becomes the 147 Scientific Writing editor’s responsibility if the journal accepts a piece of work that proves to be duplicated. If more than 10% of a paper overlaps with another paper, the International Committee of Medical Journal Editors3 asks you to send in copies of the other paper so that the editorial panel can make an informed decision about the extent of any duplication of published data. No journal wants to publish papers that duplicate data that are already in press in another journal. If you want to include previous data analyses in your paper, the correct process is to cite them in the reference list. In some cases, secondary publication in another language is justifiable but only with the permission of the journal editor who may impose certain conditions.
The correct view (with just as does not have any functional significance cheap antabuse 500mg overnight delivery symptoms at 4 weeks pregnant.

While the knees will knock together When hip flexion contractures are present, gravity forces in a patient with good walking ability and thus hamper the flexed knees downward on the side on which the progress, the increased internal rotation may be useful if muscle tone is strongest.

When patients with poor body control and impaired accordingly: on the one side there is flexion, adduction balance reactions try and remain upright but then sink and internal rotation, while on the other there is flexion, toward the floor, both legs knock against each other and abduction and external rotation. This just about enables sitting, because the patient tends to fall to the side over such patients to stand. If the knee faces forward, or even the adducted and internally rotated hip.

Hip centering measurements: The standard measure- ments are the center-edge (CE) angle according to Wi- berg (normally over 15°) and the Reimers migration in- dex according to Reimers (normally below 22%) (⊡ Fig. Both measurements are based on the AP x-ray and can only record the lateral component of a dis- location. The latter method in particular is generally used nowadays for evaluating hip x-rays. Normal results can sometimes be measured for purely anterior or posterior dislocations! Radio- graphs only show the component of a dislocation that is directed parallel to the x-ray plane. The rounded lateral acetabular epiphysis on the left side The appearance of the lateral acetabular epiphysis has also (arrow) is an at-risk sign for dislocation, even in a well centered joint proved an effective indicator: If the lateral acetabular epiphysis is rounded off at the edges the hip must be considered to be at risk despite good centering on the AP view. By contrast, a lateral acetabular epiphysis with sharp edges is an indication of a stable situation even if the joint is slightly off center (⊡ Fig. Frequency and occurrence The worse the motor control of a patient’s locomotor ap- paratus, the more likely it is that hip dislocation will oc- cur. In cases of severe spastic tetraparesis the frequency is as high as 60–70%, whereas dislocations are rare in spastic hemiparesis or diparesis (7%). Pathogenesis Dislocation develops as a result of the exertion of constant pressure by the femoral head against the lateral acetabular epiphysis, often as a result of the unfavorable positioning of the patient. If the patient lies on his side, one hip will be constantly adducted, while the other will be abducted ⊡ Fig. Patients with severe cerebral locomotor dis- legs press against each other under the influence of gravity and tilt orders move very little and tend to lie in the same position the pelvis obliquely.
