A patient with 25% superficial partial-thickness burns TBSA was treated with superficial debridement and Biobrane application discount nimotop 30 mg without prescription. It is widely used to provide temporary closure of superficial burns and donor sites. Biobrane gloves on superficial hand burns reduce discomfort and increase motion, allowing earlier aggressive physiotherapy. The major problems with Biobrane are its expense and its lack of inherent antimicrobial properties. Largo, FL) is a bioengineered human fibroblast-derived temporary skin substitute that has similar properties to Bio- brane and can be used in a similar way (Fig. The outer layer of TransCyte, the synthetic epidermal layer of nonporous silicone net, is biocompatible and protects the wound surface from detrimental environmental effects. It is semi- permeable to allow fluid and gas exchange, which keeps a healthy moist, wound healing environment. The inner layer, the bioengineered human dermal matrix, adheres quickly to the wound surface and contains the dermal components known to promote healing of the burn. The product contains essential human structural and provisional matrix proteins, glycosaminoglycans, and growth factors known FIGURE 8 TransCyte is a bioengineered human fibroblast-derived temporary skin substitute with similar properties to Biobrane that can be used in a similar way (Adapted from Smith Nephew) Superficial Burns 175 to facilitate healing. The patient’s epithelial cells proliferate and migrate across the wound, resulting in rapid wound healing. TransCyte presents with physical properties, risks, and complications similar to those of Biobrane. This layer is inert and adheres only to dry healthy skin and not to the moist wound bed. The release film is transparent, allowing the wound to be visible during application. The structure of Mepitel allows exudate to pass into an outer absorbent dressing. Mepitel prevents the outer dressing from sticking to the wound and therefore minimizes trauma and pain during dressing changes. Dressings can be left in place for several days, avoiding repetitive dress- ing changes and minimizing pain. It provides a moist wound environment that promotes re-epithelialization.

They trained lay leaders nimotop 30mg lowest price, who then led large groups of arthritic pa- tients (and family or friends where they wished to attend) in largely experi- ential learning for six weekly 2-hour groups discount 30mg nimotop with mastercard. Gains in pain and activity frequency were comparable to those from similar CBT programs; changes in depression, low at the outset, were modest, and there were none in self- rated disability. Although this is now a widely replicated model, and there are doubtless deficits in knowledge and strategies to be remedied among 284 HADJISTAVROPOULOS AND WILLIAMS chronic pain patients, the model cannot be extrapolated unquestioningly to populations of patients who are frequent users of health care and are signif- icantly distressed and disabled. Attending support groups over a 1-year period shows no enhanced treatment gains in terms of sick leave, function, and pain (Linton, Hellsing, & Larsson, 1997). Together the just cited studies suggest support groups may have a place as an adjunct approach among chronic pain patients, but provide evidence against reduc- ing the level of expertise and time and resources put into CBT group pain management programs. Commentary In 1992, Keefe and colleagues expressed widely held hopes that research us- ing larger sample sizes would demonstrate the “active ingredients” of CBT treatment packages; discover how to improve maintenance of treatment gains; and extend CBT to other patient groups, such as those with osteo- arthritis, rheumatoid arthritis, and sickle-cell disease. Meanwhile, extensive CBT programs have been subject to cost cutting, thereby reducing the quality and quantity of established treatment facilities. Research has been limited largely to small volunteer studies, making it particularly hard to model change in treatment (and maintenance after treatment) or to carry out stud- ies with sufficient sample size to do justice to the many interacting vari- ables affecting outcome. The questions identified by many clinicians and researchers (Turk, 1990), and to which some anticipate answers from large treatment studies or meta-analyses, are, “Which are the right and wrong patients? Meanwhile, no consistent findings have emerged from many component dismantling trials (see Morley et al. This is not so remarkable given that all investiga- tions are subject to local peculiarities of referral, funding, and acceptance and rejection criteria. We can, however, draw some practical suggestions from mainstream psychology: People with major depressive disorder are unlikely to engage or participate until they have more hope and sense of a tolerable future, so immediate treatment of depression is indicated; pho- 10. PSYCHOLOGICAL INTERVENTIONS AND CHRONIC PAIN 285 bias of groups or health care settings may preclude common methods and settings for delivery. As for “essential ingredients,” the implicit model of component disman- tling studies of additive, independent, and specific component-outcome re- lationships is too far from reality to provide an adequate model for analy- sis. One can no more ask which are the essential ingredients of a cake— butter, sugar, flour, or eggs. The absence of any, or serious compromises of quality, will result in a different and inedible end product; minor variations in one or another or the addition of cocoa or currants does not render it in- edible. The interaction of components (the mixing and cooking process) is crucial, yet team processes and program integration are rarely described. At a risk of stretching the analogy too far, the skills of the cook are also rele- vant, and cost-cutting pressures on programs are likely to reduce efficacy.

At the start of the 1980’s an instrumentation system that introduced new elements in the surgical treatment of Surgery can not only halt the progression of scoliosis, scoliosis was developed by Cotrel and Dubousset in France but can (to a certain extent) straighten the curvature. This system allows the curvature to be corrected and essentially maintain the correction after the spinal in three dimensions and provides stable fixation with a fusion has stabilized. Hooks and screws can be fixed to cated in thoracic scolioses from a Cobb angle of 40° bendable rods at any desired point and in any desired po- and, in thoracolumbar or lumbar scolioses, from a Cobb sition. The treatment of thoracic scoliosis in this system is angle of 50° or if decompensation is present. The disad- based on the principle of inserting several hooks (usually vantage of all existing surgical procedures is the need to 4) at certain points on the concave side. The rod is then rotated through 90° in The era of the surgical treatment of scoliosis began with the dorsal direction, i.
