Consideration of the clinical history and an understanding of trauma mechanisms are essential if an accurate diagnosis is to be made discount atorlip-10 10mg mastercard. No skull fracture pattern is pathognomonic of NAI but fractures of the parietal and occipital regions are more common than frontal bone fractures2. However, accidental skull fractures also typically present as simple linear fractures within the parietal region and therefore each case must be considered individually (Fig. They have been described as ‘corner’ or ‘bucket handle’ fractures but in reality they are identical and the different appearances are due to variations in the angle of the incident beam5,16. Metaphyseal fractures are often clinically occult and are not associated with symptoms of redness, pain, heat or 198 Paediatric Radiography Fig. The lower limbs are the commonest sites for metaphyseal fractures (knees and ankles) but any long bone metaphysis is susceptible as this is the area of most recent ossiﬁcation and is the weakest part of the immature skeleton17. The dating of metaphyseal fractures is difﬁcult as the healing process may occur without the formation of callus (Figs 9. Diaphyseal fractures Diaphyseal fractures are the commonest non-accidental skeletal injury and are a highly suspicious indicator of abuse if found in non-ambulant infants16. A trans- verse fracture pattern presents more frequently than a spiral fracture but the latter is more suggestive of abuse as it results from a twisting force (Figs 9. The most commonly injured long bones are the humerus, femur and tibia; however, care must be taken not to confuse the ﬁne spiral ‘toddler’ fracture (Chapter 7) with a physical abuse injury. Periosteal elevation The periosteum is the outer sheath of bone and it consists of an inner osteogenic layer and an outer ﬁbrous layer. Strong ﬁbres bind the periosteum ﬁrmly to the epiphysis but these attachments are weaker along the disphyseal portion of the long bone and therefore periosteal elevation can occur following subperiosteal Non-accidental injury 199 Fig. Periosteal elevation, although commonly seen on radiographs of physically abused children, is a non-speciﬁc condition and care should be taken when examining infants. It is thought that as a response to rapid growth, up to 40% of infants under 4 months of age will show radiographic evidence of periosteal reac- tion5 but unlike a traumatic periosteal response, the appearances are symmetri- cal and do not extend to the metaphysis. Periosteal elevation is a clinically occult injury and healing is through gradual resorption and consolidation of new bone.

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.
