Numerous illustrations from the earliest his- torical records testify to the existence of such treatments [3, 7, 8]. In the 19th century, the fixation technique was significantly improved with the introduction of plaster. The actual plas- ter of Paris cast was invented by the Dutchman Antonius Mathysen in 1851. A particularly discriminating approach to fracture management, with standardization of treatment according to the type of fracture, was developed by Lorenz Böhler in Vienna at the start of the 20th century.

Evidence from psychosocial and biological perspectives points towards mechanisms that link chronic pain to internalizing disorders order antivert 25mg online medicine examples. Such evidence indicates that the internalizing-externalizing model may provide a useful framework for suggesting new directions for research on connections between chronic pain and mood buy antivert 25 mg with amex medicine wheel wyoming, anxiety, and related disorders and traits. Karger AG, Basel Introduction Common mental disorders – those involving mood dysregulation, anxiety, substance misuse, and antisocial behavior – are frequently comorbid [1–4]. Indeed comorbidity is often the rule, rather than the exception, in clinical prac- tice [5, 6]. Nevertheless, patterns of comorbidity among common mental dis- orders are also systematic. Mental disorders involving depression and anxiety co-occur frequently enough that they can be conceptualized as elements within a broad spectrum of ‘internalizing’ disorders. In addition, mental disorders involving substance misuse and antisocial behavior can be conceptualized as elements within a broad spectrum of ‘externalizing’ disorders, a spectrum dis- tinct from the internalizing spectrum. Together, the internalizing and external- izing spectra form a model of comorbidity among common mental disorders Internalizing: Externalizing: distress expressed inwards distress expressed outwards Antisocial Substance Depression Somatization Anxiety Impulsivity behavior misuse Fig. Heuristic diagram of the IE structural model of comorbidity among common psychopathological syndromes. This kind of model is referred to as a structural model because it points towards the personality structures (the internalizing and externalizing spectra) that link various common mental disorders and help explain why common mental disorders show specific patterns of co-occurrence. Under this model, internalizing can be understood as a tendency to express distress inwards, placing the person at odds with themselves, and is manifested as syndromes that involve problems like depression, somatization, and anxiety. Similarly, externalizing can be understood as a tendency to express distress outwards, placing the person at odds with others and society, and is manifested in syn- dromes that involve problems like antisocial behavior, substance misuse, and impulsivity. As shown, syn- dromes involving depression, somatization, and anxiety are linked together as elements within the broader internalizing grouping. Similarly, syndromes involving antisocial behavior, substance misuse, and impulsivity are linked together as elements within the externalizing grouping. In addition, the inter- nalizing and externalizing groupings are linked at a higher level by the presence of distress in all common mental disorders. That is, the model states that all common forms of psychopathology involve distress, which can be internalized or externalized, and subsequently expressed as the specific syndromes listed at the bottom of figure 1. Emerging evidence suggests that this model organizes not only the observed, or phenotypic structure of common forms of psychopathology, but also underlying patterns of genetic risk for these syndromes. That is, emerg- ing evidence suggests that internalizing problems go together because they are linked by common genetic factors. Similarly, externalizing problems go together because they, too, are linked by common genetic factors – factors sep- arate from those that link internalizing problems. The model therefore has high Krueger/Tackett/Markon 64 utility for organizing the search for genes that confer risk for the development of numerous common forms of psychopathology. The goal of the current chapter is to extend this model to a new and rela- tively uncharted area at the interface between mental disorders and medical dis- orders: chronic pain. We begin with a review of literature pointing toward psychosocial and genetic mechanisms that may help to explain relationships between pain and other internalizing phenomena. We then turn to a discussion of some of our recent research locating somatic syndromes (including pain symptoms) within the internalizing spectrum of the internalizing-externalizing (IE) model. We conclude by discussing how the IE model could help organize research on psychosocial and genetic mechanisms that undergird the internal- izing spectrum, including chronic pain. Psychotherapeutic Treatments for Depression and Chronic Pain Cognitive behavioral therapy (CBT) techniques were originally developed in the 1950s and 1960s, initially to be used in treating depressive disorders. However, the effectiveness of CBT techniques has also been demonstrated in individuals with chronic pain. Studies often show that CBT focused on pain- related symptomatology is effective in reducing both pain-related symptoms and depressive symptoms as evidenced by typical measures of these symptoms [14–16]. Benefits of CBT on pain-related symptoms have also been evidenced using an external criterion such as number of days of work missed following treatment. These results have also been demonstrated in the use of CBT with children and adolescents. In addition to CBT, behavioral techniques often used to treat depression and anxiety have been used as effective treat- ments for chronic pain. Furthermore, even aerobic activity has been found to aid both depression and pain. Putative Mechanisms Underlying Psychotherapeutic Treatments A related line of research has sought to identify common underlying mech- anisms in depression and chronic pain that may explain why some treatments are effective for both.

Through modification and improvement of techniques to ensure local doses are in line with those nationally recommended cheap antivert 25mg line symptoms vomiting diarrhea, this will standardise radi- ation exposure for specific radiographic examinations 25mg antivert sale symptoms during pregnancy. However, it is likely that the national dose reference levels will, at least initially, be calculated only for the adult population as difficulties in establishing dose reference levels for paedi- atric examinations exist due to the wide variation in patient size and composi- tion throughout the paediatric age range5. Even without national dose reference levels for paediatric examinations, there is much that can be done within clinical departments to ensure that unnecessary exposure to ionising radiation is minimised. The IR(ME) regulations emphasise the necessity for ‘justification and optimisation’ of radiographic exposures as an essential step in the radiation protection process and stress that any examination that does not have a direct influence on patient management should not be undertaken. Unfortunately, unnecessary examinations are still requested by 21 22 Paediatric Radiography Box 3. Justification: No practice involving exposure to radiation should be adopted unless it produces net benefit to those exposed or to society Optimisation: Radiation doses and risks should be kept As Low As Reasonably Achievable (ALARA), economic and social factors being taken into account; con- straints should be applied to dose or risk to prevent an unacceptable degree of exposure in any particular circumstance Limitation: The exposure of individuals should be subject to dose or risk limits above which the radiation risk would be deemed unacceptable Adapted from National Radiation Protection Board (1994)2 clinicians who are unfamiliar with modern imaging techniques and concerns have been raised over the level of training in radiological techniques that cur- rently exist within undergraduate medical courses6. Justification, as the first step in radiation protection, implies that the necessary diagnostic information cannot be obtained by other methods associated with a lower risk to the patient, and that there is sound clinical evidence to suggest that the patient will benefit from the investigation in terms of treatment and man- 1 agement. It is important that any person justifying a radiation exposure has an understanding of the balance between the benefit and the risk of the exposure. Once a diagnostic examination has been justified, the subsequent imaging process should be optimised by considering the interplay between three impor- tant aspects of the imaging process: (1) The diagnostic quality of the radiographic image (2) The radiation dose to the patient (3) The choice of radiographic technique All three components need to be carefully considered if the quality and value of the imaging examination is to be optimised. However, differences in the anatomical and developmental features of a child, as well as varying body pro- portions, can make this task difficult and an understanding of the anatomical and developmental changes that occur during infancy, childhood and adoles- cence are essential. The European Guidelines on Quality Criteria for Diagnostic 5 Radiographic Images in Paediatrics presupposes that practising radiographers already have a knowledge of the changing radiographic anatomy of the devel- oping child but much of this knowledge must be gained experientially as there are few texts to support learning in this area. As a result, radiographers who do not regularly examine children may have difficulty adapting radiographic anatomy from the adult patient to the child. Patient positioning Incorrect positioning is the most frequent cause of inadequate radiographic image quality in paediatrics5 and, although it is generally accepted that the Radiation protection 23 correct positioning of paediatric patients can be much more difficult than posi- tioning co-operative adult patients, this should not be used as an excuse for substandard image quality. The acceptability of an image as diagnostic depends upon the clinical question posed and it may be that, in certain circumstances, a lower level of image quality may be acceptable for certain clinical indications. However, inferior image quality cannot be justified unless it has been intention- ally designed and is associated with a reduced radiation dose to the patient. The fact that the patient was unco-operative should not be used as an excuse for producing inferior quality images, which are often associated with excessive dose, as no diagnostic radiation exposure should be made unless there is a high probability that exact positioning has been achieved and will be maintained for the duration of the exposure (see Chapter 2). Field size and beam limitation Inappropriate field size is a common fault in paediatric radiographic technique and correction is an effective method of reducing unnecessary dose to the patient. Correct beam limitation requires the radiographer to apply precise knowledge of external anatomical landmarks to the paediatric patient being examined. However, these landmarks vary with the physical growth and development of the child and are, therefore, not necessarily identical for children of similar ages. In addition, the field size depends much more on the nature of the underlying disease in infants and younger children than in adults (e. Accepting the importance of accurate collimation to the area of interest as a method of reducing dose is further emphasised in the European Guidelines on 5 Quality Criteria for Diagnostic Radiographic Images in Paediatrics. These guidelines state that the maximum field size tolerance should be less than 2cm greater than the area of interest and this is further reduced to a tolerance of 1cm in neonates. Consequently, appropriate quality assurance testing of mobile and stationary radiographic equipment to ensure that the light beam diaphragm cor- relates with the radiation beam is vital if consistent and accurate collimation is to be achieved. Protective shielding For all paediatric examinations, the consistent use of lead rubber to shield that part of the body in immediate proximity to the diagnostic field is essential. Experimental data have shown that, when using exposures in the range of 60– 80 kV, a reduction in gonadal dose of up to 40% can be achieved when 0. However, this reduction in dose is only possible if the lead protection is placed at the field edge. Lead rubber 24 Paediatric Radiography covering placed further away is less effective and at a distance of 4cm or more has been shown to be completely ineffective as a radiation protection measure5. For examinations where the gonads lie in or near (within 4cm of) the primary radiation beam, lead protection should be applied whenever possible (Fig. Note the child is cuddling a doll to aid distraction, immobilisation and co- operation.
