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 buy albendazole 400mg. 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.

Only the inner part of the meniscus should be removed, leaving the outer part in place. The lateral meniscus has a very important stabilizing function, and a particularly problematic situation in this context is widening of the popliteal hiatus during resection of the posterior horn. Severe instability can result if this occurs in connection with a lesion of the anterior cruciate liga- ment, posing one of the most difficult therapeutic prob- lems for the knee. Medial collateral ligament lesions Lesions of the medial collateral ligament are likewise not especially rare in children. In many cases, avulsion occurs at the cartilaginous proximal attachment.

Subjects buy albendazole 400mg without prescription, all of whom received both types of pain intervention in the within-subject design, did not indicate a significant preference for one versus the other type of intervention, and it was noted that the psychological intervention required less time (Jay et al. As a whole, results of these well-controlled studies indicate that psychological interventions are of at least comparable efficacy to standard pharmacologi- cal approaches for management of the pain associated with bone-marrow aspiration in children. It is important to note that such findings are not likely to generalize to all types of clinical acute pain. Clearly, procedures associated with more in- tense acute pain, such as even “minor” surgery, require pharmacological analgesia. However, the results reported earlier indicate that combining psychological and pharmacological approaches may have significant bene- 260 BRUEHL AND CHUNG fits to patients. MODERATORS OF RESPONSES TO PSYCHOLOGICAL INTERVENTIONS Spontaneous Coping Strategies Many individuals implement their own spontaneous pain coping strategies when faced with acute pain (Spanos et al. The possibility that externally imposed interventions may interfere with pa- tients’ implementation of effective pain control strategies already in their behavioral repertoire cannot be ruled out. Although some studies suggest that these spontaneous coping strategies may be effective for pain reduc- tion (Spanos et al. Coping Style Patients’ preferred style of coping with stress, whether Monitoring or Blunting in character, may be relevant to understanding the efficacy of spe- cific psychological acute pain interventions. Monitors, also referred to as Sensitizers or Vigilants, prefer to cope with stressful situations by seeking out information about the stimulus, and by monitoring and trying to miti- gate their responses to the stimulus (Schultheis, Peterson, & Selby, 1987). Blunters, also termed Repressors, Avoiders, Distractors, or Deniers, prefer to cope with stressful situations through avoidance and by denial of the stressor (Schultheis et al. A number of studies have hypothesized that psychological acute pain in- terventions work best if they match an individual’s naturally preferred cop- ing style. For example, providing a sensory focus intervention to a Blunter would be considered a mismatched intervention, whereas a relaxing imag- ery strategy would be considered a matched intervention for such an indi- vidual (Fanurick et al. Laboratory acute pain studies have provided some evidence indicating that interventions matched to preferred coping style result in more effective reductions in acute pain responsiveness (e. PSYCHOLOGICAL INTERVENTIONS FOR ACUTE PAIN 261 Clinical studies regarding this issue are mixed, but generally negative. Although there were no interaction ef- fects regarding pain experienced during the procedures, Monitors were found to experience less distress in the information provision condition whereas Blunters experienced greater distress (Shipley et al.
