The orthosis must be of a can be achieved only by means of an external appliance rigid design since it has to replace the absent muscle activ- (orthosis) or a surgical procedure generic geriforte 100 mg line. During walking, the orthosis prevents the premature throdesis of the lower ankles (usually an extra-articular forward movement of the tibia in relation to the foot in Grice operation) is performed to stop the foot from going contact with the ground and ensures adequate knee exten- over. For growing children there is no alternative to an ing valgus component of the foot. An excessive dorsiflex- orthosis, since an arthrodesis will inhibit foot growth and ion, as also observed in insufficiency of the triceps surae, leave the feet smaller than normal. Only on completion remains, and this is much more disruptive from the func- of growth can the orthosis be replaced surgically with an tional standpoint. Since an orthosis will still be required arthrodesis, which must incorporate the upper and lower the benefit for the patient from a procedure such as the ankle. Due to a lack of mobility, and hence of compensa- Grice arthrodesis is minimal. Maintaining mobility is therefore favorable Structural deformities in functional feet, especially if sensation is not normal. A Structural deformities in primarily flaccid locomotor disor- muscle transfer procedure to replace the absent plantar ders and muscular dystrophies are shown in ⊡ Table 3. Although good results have been Structural deformity of the foot caused by reduced or described, our everyday experience with our patients has absent muscle activity. The shortening of the Achilles tendon represents a Definition logical alternative. However, this procedure is reputed to A contracture of the triceps surae muscle is present, produce poor results. Although it can prove helpful in regardless of the muscle activity and power, which extreme cases, the chances of a good result in neuro-or- prevents dorsiflexion even with a flexed knee. This must be prepared difficult for the body to keep in balance over the flaccid leg. Otherwise the only bilizers that would have to keep the foot on tiptoe are also option for protecting the knee from giving way in flexion insufficient. The foot skeleton becomes deformed and fixes is by supporting it with the hand ( Chapter 4. The ability to A slight hyperextension of the knee of up to 5° is 3 walk and stand can be further impaired as a result. Ideally, the hyperextension should be permits weight-bearing without deformation of the foot prevented indirectly by a corresponding orthosis for the skeleton. If a functionally disruptive contracture is pres- lower leg and foot with an integrated heel. An overcorrection will lead to a pes calcaneus position with corresponding flex- ion at the knees and hips, thereby compromising walk- ing and standing. If the knee and hip extensors are not available for compensation (as in muscular dystrophies), a slight overcorrection will result in the loss of the abil- ity to walk and stand. Since the lengthening procedure does not need to take account of the muscle power, it can be implemented in the form of tendon lengthening. One surgical technique for correcting the equinus foot in flaccid paralyses is the rearfoot arthrodesis according to Lambrinudi (⊡ Fig. This procedure is risky to the extent that dorsiflexion is not blocked at the ankle. If the knee and hip extensor muscles are not strong enough to compensate for the lack of power in the triceps surae, a crouch gait will result. The equinus foot is an important aid to stabilization during standing and walking, particularly in muscu- lar dystrophy patients and patients with post-polio syndrome. A slight case of equinus foot blocks the upper ankle and prevents dorsiflexion.
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 cheap geriforte 100mg on line. 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 100mg geriforte with amex. Although some studies suggest that these spontaneous coping strategies may be effective for pain reduc- tion (Spanos et al buy geriforte 100mg free shipping. Coping Style Patients’ preferred style of coping with stress buy geriforte 100mg with mastercard, 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. Studies performed in the context of more severe acute clinical pain, on the other hand, are more negative. In a study of general surgery patients, efficacy of information pro- vision, relaxation, and no intervention was compared as a function of Moni- toring and Blunting coping styles (Scott & Clum, 1984). Blunters reported less pain and used less analgesics when provided with no intervention, which appear at least not inconsistent with the matching hypothesis. How- ever, contrary to the matching hypothesis, Monitors appeared to do best with breathing relaxation as opposed to information provision (Scott & Clum, 1984). Work by Wilson (1981) also in general surgery patients found that Blunters did not experience exacerbated pain following an information provision intervention, again failing to support the matching hypothesis. More recent work in surgical patients also indicated that efficacy of a relax- ation intervention did not differ depending on the degree to which patients preferred a Monitoring coping style (Miro & Raich, 1999). Differences in the measures used to assess coping style, types of interventions employed, and other procedural details make comparisons across studies more difficult. However, clinical support for a coping style by intervention type matching hypothesis is at best weak. Moreover, the absence of validated clinical pro- cedures for determining preferred coping style for purposes of selection of intervention type (e. Other Potential Moderators As noted previously, there is evidence from several studies that interven- tions including sensory focus, breathing relaxation, and use of control- enhancing statements reduce the discomfort of dental procedures only among those with a high desire for control and a low level of perceived con- trol prior to intervention (Baron et al. Given the importance of perceived control in determining satisfaction with acute pain management (Pellino & Ward, 1998), these findings suggest that if resources for providing psychological acute pain interventions are lim- ited, it may be most appropriate to focus these resources on individuals who express a desire for greater control over the acute pain experience. Laboratory acute pain research has indicated that imagery, analgesia suggestions, and distraction were effec- tive for reducing acute pain only among individuals high in hypnotizability (Farthing et al. This might not be considered surprising given that individuals high in hypnotizability may be more capable of developing vivid mental imagery (Farthing et al. As with coping style, validated clini- cal criteria for making treatment decisions based on assessment of hypno- tizability are not available. Therefore, the practical clinical utility of this moderator variable is questionable. BARRIERS TO EFFECTIVE CLINICAL USE OF PSYCHOLOGICAL INTERVENTIONS FOR ACUTE PAIN If psychological interventions for acute pain can be clinically useful in some circumstances, as appears to be the case, what are the barriers to their use? A study by Jiang and colleagues (Jiang, Lagasse, Ciccone, Jakubowski, & Kitain, 2001) of hospital acute pain management practices indicated wide- spread underutilization of nonpharmacological techniques. A primary fac- tor contributing to this underutilization was resource availability (Jiang et al. With the current focus on reduction of health care costs nation- wide, cost containment becomes a major barrier to providing the trained personnel and staff time to implement many psychological pain manage- ment strategies in situations in which they have proven effective.
It is much better to have an inclusive title and detailed row and column descriptors than to put the essential information into footnotes purchase 100 mg geriforte with visa, which should be avoided as far as possible buy geriforte 100 mg without prescription. Readers will not want to search the text discount geriforte 100mg with mastercard, the title purchase 100 mg geriforte amex, and the row and the column headings of the table before finally going to footnotes to find the information that they need before they can interpret your findings. Finally, tables should be submitted on separate pages and not incorporated into the text. It is common practice to print tables one to a page and include them at the end of the manuscript. Figures and graphics Art does not reproduce what we see; rather, it makes us see. Paul Klee (1879–1940) 78 Writing your paper Figures and graphs are essential for conveying results in a clear way. A cryptic approach is to show your most important findings as a figure, but only as long as the figure does not take up much more space than reporting the data would. The figure in which you present your main results should be totally self-explanatory and have a bold, stand-alone quality. A good figure tells the story in a single grab and stays in a reader’s mind. Such figures are often taken up by other researchers in their talks to wider audiences and thus help to promote your work. Figures that you use in talks to colleagues are often too simplified for a journal article in which all of the details must be included in the absence of any accompanying oral explanations. However, figures with too much detail become complicated and difficult to understand when the message gets lost in the graphics and the explanations. The symbols, abbreviations, hatching, line types, and bars must all be very clear and must be explained in detail without cluttering the picture. Also, the figure legend should be comprehensive so that the figure can be fully understood without recourse to reading explanatory text in the results section. Pie charts, which are often useful in oral presentations, have few applications in published journal articles. They are space greedy, the information cannot usually be used to provide an accurate comparison of results between groups, and the numbers are usually better accommodated in a table or bar graph, which takes less space. When creating a figure, always shrink the printed copy down to the size that it will be in the final copy of the journal and then examine it for legibility. Your work may have to survive a massive reduction during the publication process. Labels that are very readable on an A4 sheet often lose clarity when shrunk into a much smaller format. The most readable figures have large legends and axes descriptors, and use hatching and markings that discriminate clearly between groups.

Fine shades of grey or different colours that look sophisticated in A4 size or in a graph for an audiovisual presentation can look amazingly similar when reduced for publication in black and white. It is important to try and resist being carried away into the world of computer-generated graphics. Figures should be simple to interpret, uncluttered, and free of extra lines, text, dimensions, and other gimmicks. Never be tempted to use three-dimensional “box” histograms rather than single dimensional histograms. Such histograms are best left as marketing tools because the third dimension has no meaning when presenting scientific results and can create false impressions. The third dimension is not only distracting and meaningless but can prevent readers from being able to interpret the results by comparing the degree of overlap between the 95% confidence intervals. Multidimensional histograms are occasionally used to depict the interactive 80 Writing your paper 30 Neutral Negative Positive Negative:positive ratio 20 10 0 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 Middle year (of three) of publication Figure 3.
This allows for easy inspection of the burn wound if a definitive plan of treatment is still to be outlined or a new or more senior burn surgeon needs to inspect the wound to make the final treatment plan geriforte 100 mg fast delivery. As soon as the initial management and resuscitation of burn patients is complete the determination of the wound treatment plan is the main focus during this phase of patient care geriforte 100 mg cheap. It is essential to outline the surgical plan in order to institute the rationale of dressing changes and the choice of dressing materials order geriforte 100 mg with amex. Depending on the size and depth of the burn wound buy generic geriforte 100mg on-line, the approach to wound care and closure will differ, and so will the rationale for wound care and dressings. Wounds of this type heal without surgical intervention; therefore, the topical treatment and choice of dress- ings will have a direct impact on the patient’s comfort and wound healing. The type of surgical intervention, especially the timing of excision and extent of the excision, will determine the type of wound care management patients require before and during burn wound closure. BURN WOUND MANAGEMENT BASED ON THE DEPTH OF THE WOUND Burn injuries damage different degrees of the epidermis, dermis, and soft tissues. Depending on the depth of the injury, wounds will present with different abilities for healing and re-epithelialization. Superficial wounds will present with good chances for complete wound healing within 3 weeks, whereas deep wounds have lost most or all possibilities for spontaneous wound healing. State-of-the-art wound care is therefore essential in superficial wounds to warrant and stimulate spontaneous wound healing. Surgery and operative wound closure will play a central role in the management of deep wounds. In general, patients can be categorized to three broad groups depending on the type of injury sustained: 1. Deep partial and full-thickness burn Patients’ local wound treatment and surgical plans are based essentially on the type of injury (see Table 1). Superficial burns include all those injuries that have destroyed the epidermis and different degrees of the papillary dermis. They are represented by first-degree TABLE 1 Management of the Burn Wound Superficial partial-thickness burns: conservative treatment Deep Partial and full-thickness burns: excision and autografting Indeterminate-depth burns: Conservative treatment (10–14 days), followed by second inspection and definitive treatment (based on healing time) Wound Management and Surgical Preparation 87 (or epidermal burns) and superficial second-degree burns (or superficial partial thickness burns). Indeterminate-depth burns include those injuries that can be classified neither as superficial nor as deep burns. Their potential for regeneration is also variable, and a period of conservative treatment followed by a second assessment and definitive treatment plan is usually required. Deep second-degree and third-degree burns represent deep partial and full-thickness burns. They do not represent any treatment problem, and surgery is normally the treatment of choice. Most or all dermal appendages have been destroyed, and regeneration proceeds slowly or never occurs. The debate continues as to the timing of surgery, especially for patients with massive injuries. Superficial burns A conservative approach is mandatory in this type of injury. When they heal in less than 3 weeks they leave minor skin changes or no scars at all. The period that these injuries require for complete healing is mandated by the speed of debridement of all devitalized tissues and the proliferation of basal cell epithelial cells. Treatment should be therefore directed to speed or promote debridement of all debris caused by burning and to provide a microenvironment that allows and promotes re- epithelialization. Many topical treatment regimens are available in the market for treatment of superficial burns. Many topical antimicrobial creams for the tempo- rary skin substitutes are available. The application of topical creams for the treat- ment of partial-thickness burns has been and still is favored by many burn care physicians. This treatment protocol proved to be effective in the late 1960s and early 1970s and allowed for better control of burn wound sepsis. The application of topical creams requires frequent dressing changes and produces severe pain and anxiety. Patients refer to these as among the most painful and frightening experiences in their lives.
