Lastly purchase prednisolone 5mg, we discuss where ultrasound is a weaker alternative to other more com- prehensive methods buy prednisolone 40mg with amex, such as in the detection of periosteal reaction over an area of osteomy- elitis prednisolone 40mg with visa. We do not cover those areas of musculoskeletal practice where ultrasound has no current role order prednisolone 20 mg line. For example safe prednisolone 5 mg, CT and MRI are the most effective means of making a diagnosis of hind- foot coalition, but ultrasound cannot show us the deep structures. X Contents Ultrasound machines vary widely in their ability to realise images of superficial lesions. In musculoskeletal applications most lesions are near the surface and care must be taken to select the best equipment. Even the latest machines may fail in this area, and thorough knowledge of the technology is important to guide our patients to effective diagnosis and treatment. Ultrasound, CT and MRI demand a wide knowledge of anatomy, including variations of normal. Ultrasound is a dynamic examination, and the examiner must also understand the biomechanics and function of the regions studied. The authors of the chapters in this book are all renowned musculoskeletal imaging spe- cialists. They have been briefed to discuss all the imaging appropriate to a suspected diagno- sis, and we hope that the reader will gain an understanding of where each method fits into a modern practice.

Cheung The goals of diagnosis and treatment are to permit affected children to walk normally and to prevent premature degeneration. The manoeuvres of Ortolani and Barlow are effective in detecting around 74% of cases of dislocation or subluxation that may be demonstrated on imaging. The level of training and experience required to accurately perform these tests is substantial, and sadly the task is often placed in the hands of the more junior members of the team. There are undoubtedly occa- sions when a child with DDH is overlooked when a clinical abnormality might have been detected by a more experienced clinician. Training and audit of practice are crucial, but even in the best hands there will be errors, as clinical manoeuvres alone are not capable of detecting every case. Indeed it is also likely that some stable hips become unstable, and if the timing of the clinical examination does not coincide with this developing problem then a child may miss the chance of early treatment that could potentially limit or reverse the process. The need for early diagnosis is based on the window of opportunity that exists in the first few months of life when relatively simple treatment may be very effective. Methods range from wearing double nappies to splint therapy and corrective sur- Fig. This examination is part of a full skeletal harder the treatment will be, leading to greater risk survey. There is a real need for a method of diagnosis that is simple, cheap, safe and effective, and US arguably provides such a technique.

Core and surface temperatures in burned patients are elevated to 2 C above normal by a centrally mediated resetting of the hypothala- mus purchase prednisolone 10 mg mastercard. Energy to maintain body heat is provided by futile substrate cycling of carbohydrate and lipids at the expense of protein catabolism quality 10 mg prednisolone. Stable isotope studies have identified simultaneous glycolysis and gluconeogenesis (using amino acids as substrate) discount prednisolone 40mg amex, and continuous cycling of triglycerides and fatty acids discount 20 mg prednisolone free shipping, which expend large amounts of energy in the form of heat quality prednisolone 20 mg. NUTRITIONAL SUPPORT Maintenance of body weight, lean body mass (muscle protein), electrolytes, and vitamin homeostasis are the primary objectives of nutritional support of the burned patient. Without proper nutritional support, hypermetabolic patients can lose up to 25% of their preadmission body weight in the first 3 weeks postburn. Weight loss of up to 30% of body mass was common in burn patients prior to the use of continuous feeding. It is possible to maintain body weight, and/or lean body mass or achieve weight gain, using enteral and/or parenteral nutritional support. It has been demonstrated on many occasions that body weight can be maintained with milk- or soy-based formulations [17–20]. The amount of nutri- tional support required correlates well with resting energy expenditure (REE). REE can be measured directly at the bedside using portable calorimeters that analyze oxygen consumption and carbon dioxide excretion. Formulae have been derived from regression analysis of predicted caloric intake compared with mea- sured weight loss in large patient series, or by direct measurement of metabolic rate using indirect calorimetry. These estimate the energy requirements of patients to maintain body weight. Body weight maintenance has been successfully demon- strated in large numbers of hospitalized patients using these formulae. For an adult, the most commonly used formula calculates caloric needs in burn patients from body weight and TBSA burned. For children, the most appro- priate formula differs with body surface area [21–23] (Table 1). In patients with large burns this can equate to over 5000 kilocalories per patient per day for adults. Although these provide reliable guides, a better estimate of actual energy expenditure is made using a mobile calorimeter at the bedside. Double-labeled water techniques (which enable caloric balance to be studied over time, e. Calories delivered at rates higher than this maintain lean body mass, but stimulate weight gain in patients only through 296 Murphy et al.

Optimal nutritional support in convalescent burn patients should be between 1. Skin protein synthetic rates are in- creased, however, with enhanced wound and donor site healing. Milk and the majority of available hospital diets are predominantly fat-based. A high- carbohydrate diet stimulates protein synthesis by increasing endogenous insulin. Enteral nutrition supplied predominantly as carbohydrate and protein (3% lipid, 82% carbohydrate, 15% protein) rather than as fat-based formula (44% lipid, 42% carbohydrate, 14% protein) improves the net balance of skeletal muscle protein in severely burned children. Although body weight can be maintained with a fat-based diet, actual accretion of lean body mass is only achieved using high-carbohydrate, high-protein diets. Muscle protein degradation is de- creased with a high-carbohydrate protein diet due to increased endogenous insulin production. Tight euglycemic control with insulin improves wound healing and decreases infection and mortality [29,30]. The increased nutritional requirements in burn-induced hypermetabolism may be accomplished via enteral or parenteral routes. Nutritional support in se- verely burned patients is best accomplished by early enteral feeding where possi- ble.

The basic prognosis for the clinical condition therefore depends on the extent of the primary neurological damage discount 20 mg prednisolone visa, which also restricts the life expectancy purchase 10mg prednisolone. Twenty-year survival rates of 99% and 50% have been observed for slightly disabled and severely disabled patients respectively purchase prednisolone 10 mg on-line. Regardless of the life expectancy order prednisolone 40 mg fast delivery, the question of the orthopaedic prognosis is frequently raised prednisolone 5mg visa, particularly in respect of the ability to walk. The onset of walking is generally delayed to a greater or lesser extent, however, depending on the severity of the impairment in each case. Walking freely is often difficult for patients with tetraparesis, and ⊡ Fig. Typical crouch position of the only those with mild symptoms will be able to acquire legs with slight internal rotation, good trunk control this skill. In many cases, balance is impaired by deficient trunk and head control to such an extent that the patients required added support (crutches, canes or a walker). In any case, many patients are at least able to achieve a trans- fer function in this way. Only the most severely disabled patients are hardly able to walk or stand at all, although here too any prognosis should be made very carefully. It is often asserted that walking can no longer be learned after the age of seven. Clinical experience has taught us, however, that it is perfectly possible to achieve a certain ability to walk beyond this age. One needs to define »walking« in this context: It is, of course, highly unlikely that patients of this age will be able to acquire the walking ability of neurologically normal individuals. The important point is that they can learn how to move their own weight over a few meters, perhaps only with support. The chances of acquiring such a limited walking function at this stage are particularly good if any existing orthopaedic deformities such as hip dislocations or severe contractures can be corrected. Since a motor-related prognosis is unreliable in this context, we are particularly circumspect when mak- ing any statements, particularly negative ones. Bluntly in- forming parents that »your child will never learn to walk« is demotivating and jeopardizes many therapeutic steps. The leg on the affected side is internally rotated and the knee and hip are flexed. In contrast with the situation for cerebral palsy, a fairly pronounced and troublesome spasticity develops.

The phenomenon of intelligent nonadherence buy 10mg prednisolone fast delivery, when the bene- fits are outweighed by the costs of taking the drug prednisolone 40mg without prescription, must also be recognized and addressed purchase prednisolone 40 mg with mastercard, or the physician is rendered ineffective by the patient’s in- complete account of his or her behavior prednisolone 5 mg without a prescription. Physicians’ and patients’ esti- mates of the extent of barrier to use presented by particular adverse effects differ substantially cheap prednisolone 20 mg without prescription. Therefore, eliciting the report of an adverse effect (such as dry mouth with tricyclic antidepressants) should be followed by investi- gation of its implications (such as avoiding social conversation). The cognitive approach that estimates the personal costs and benefits of adherence to recommended physical exercises may also be useful, al- though the area presents some different problems. Physiotherapists often offer too much rather than too little information (so that desirable adher- ence is hard to measure) (Sluijs, Kerssens, van der Zee, & Myers, 1998), and enjoyment of the exercise may be an important factor in maintaining exer- cise regimens (Jones, Harris, & McGee, 1998). That would suggest that intro- ducing the patient to as many as possible sports, exercise routines, and even energetic leisure activities, such as some types of dance, may encour- age adherence by finding at least one that he or she enjoys. However, ad- herence to exercise by the healthy population is notoriously low over months, and practical issues of access to facilities play an important part (Sallis & Owen, 1998). PSYCHOLOGICAL INTERVENTIONS AND CHRONIC PAIN 293 Adherence to pain management methods both during and after treat- ment programs is somewhat underresearched, and little evidence has so far accrued that can identify the extent of adherence necessary to ensure maintenance of treatment gains or improvement on them. Research evi- dence suggests that complete adherence is not necessary for a positive treatment outcome (Silver, Blanchard, Williamson, Theobold, & Brown, 1979), but rather that gains may be greater among those with the highest adherence (Parker et al. Causes of nonadherence to pain manage- ment programs have been investigated (Turk & Rudy, 1991), but measure- ment of nonadherence itself is complicated in that patients often adhere to some aspects of a program and not others (so cannot be simply divided into adherents and nonadherents for comparison). Results of this research suggest that adherence is generally low among patients (e. As noted by Turk and Rudy (1991), hundreds of variables have been studied in relation to adher- ence, and not surprisingly the results are inconsistent, with contributions to variance from components of treatment program, the injury, the pro- vider–patient relationship, social support, and patient characteristics (see Turk & Rudy, 1991). Given this evidence, psychologists can play an important role in promot- ing adherence to treatment regimens, whether the treatment is medication, physiotherapy, or other components of pain management. Four general strat- egies exist: (a) assisting the patient in modifying the environment to facilitate adherence (e. Efforts to address at least some of these dimensions have resulted in improved outcomes (Hol- royd et al. The other area where psychologists at times assist is the selection and preparation of patients for surgery. Although there is lots of evidence for psychological preparation for surgery helping a range of outcomes (e. Carragee (2001) reviewed the literature and concluded that psychological screening prior to disc surgery is of limited value in many cases, and can be viewed as useful only when less pathol- ogy is present, there have been longer periods of disability, and economic issues are present. Other variables, such as internal locus of con- trol and lower catastrophic cognitions, have also been associated with better outcomes, such as shorter time to achieve a straight leg raise follow- ing total knee replacement (Kendell, Saxby, Malcolm, & Naisby, 2001). The research is correlational in nature and does not rule out the possibility that patient anxiety reflects a realistic interpretation of the circumstances sur- rounding surgery. It is also possible, however, that anxiety serves to limit activity and thus reduces the probability of a positive outcome. In line with this interpretation, concurrent psychological intervention with surgery may serve to enhance surgical outcome. That is, psychological interventions specifically aimed at anxiety reduction and improving self-efficacy and con- trol may serve to facilitate recovery in some patients. In particular, usage of imagery and relaxation strategies following surgery was associated with significantly greater knee strength, and less pain anxiety about reinjury. Overall, there appears to be increasing support for psycho- logical interventions in improving outcomes following surgery, but clearly more research is needed in this area. PAIN IN CHILDREN Prior to concluding, it must be acknowledged that this chapter, due largely to space constraints, has focused on psychological interventions for adults with chronic pain. We recognize that psychological interventions are also used to manage pain among children and adolescents (McGrath & Hillier, 1996; see also chap. Cognitive interventions with children typically focus on modifying thoughts and coping abilities related to pain (e. McGrath (1987), in particular, strongly advocated a multistrategy approach (both pharmaco- logical and nonpharmacological) for optimal management of recurrent per- 10. PSYCHOLOGICAL INTERVENTIONS AND CHRONIC PAIN 295 sistent pain that is tailored to the child and follows from the needs identi- fied through a multidimensional pain assessment. The interested reader is encouraged to review Eccleston, Morley, Williams, Yorke, and Mastroyan- nopoulou (2002), who conducted a recent systematic review and meta- analysis that shows good efficacy, but only really for headache, and second- arily for abdominal pain and sickle cell where there has been some prelimi- nary research. There is no controlled research on several major childhood chronic problems such as juvenile rheumatoid arthritis. CONCLUSION Although psychological treatments for chronic pain have been shown to be valuable, there is far greater support for CB interventions than any other form of treatment.
