There is limited evidence (level III) to support the theory that antibiotic skin infection order line keflex, for some patients xelent antibiotic order keflex 750 mg with mastercard, a composite clinical examination per- formed by an experienced musculoskeletal specialist can bypass the need for MRI by directly identifying patients with cruciate or meniscal injuries amenable to arthroscopic repair infection humanitys last gasp discount keflex amex. However, there is also moderate evidence (level II) that MRI is a highly accurate method of diagnosing soft tissue knee injuries in patients where the clinical picture is not clear. If MRI is used in patients likely to undergo arthroscopy, there is moderate evidence (level II) indicating that it can substantially reduce the overall arthroscopy rate and limit the number of purely diagnostic arthroscopies without detri- ment to the patient’s quality of life. Supporting Evidence: The mechanism of injury, clinical history, and physi- cal examination can provide important information on the likelihood of injuries to the menisci and ligaments of the knee. Indeed, some authorities have observed that, with sufficiently experienced clinicians, these methods Chapter 15 Imaging for Knee and Shoulder Problems 279 have high diagnostic accuracy and might render the use of imaging unnec- essary prior to arthroscopy in many cases (39,40). Conversely, others have argued that MRI is an essential component of the presurgical assessment, which saves money and reduces referrals for purely diagnostic arthroscopy (41,42). Four systematic reviews have summarized the diagnostic accuracy of the physical examination for suspected injury to the cruciate ligaments and the menisci (11–14). Each review notes that most diagnostic accuracy studies interpret the reference standard, usually arthroscopy, without masking the surgeon to the findings of the physical examination and that, as in many clinical studies, verification bias (patients with abnormal physical tests were more likely to undergo the reference standard) was often present. Two reviews (11,12) included studies that reported data on composite clinical examinations without specifying the precise examination maneu- vers that were used. In general, these composite examinations resulted in reasonable sensitivity and specificity for anterior cruciate ligament (82% and 94%, respectively), posterior cruciate ligament (91% and 98%), and meniscal (77% and 91%) injuries (12). However, it is very difficult to repli- cate or generalize these findings given the lack of detail about the indi- vidual components of the examination. To date, the majority of studies have been conducted by musculoskele- tal specialists skilled in physical examination techniques. Given the inevitable methodologic flaws in many of these studies, we conclude that there is limited evidence (level III) that the clinical examination can accu- rately select patients most likely to benefit from therapeutic arthroscopy. The rise in MRI utilization is probably due to increased availability of equipment and reluctance on the part of physicians to rely solely on the clinical examination to determine treatment. Furthermore, some legal judgments have criticized surgeons for operating without full information about the extent of the lesion(s). However, overreliance on advanced imaging technology might be counterproductive if MRI is not sufficiently accurate. In particular, age-related degeneration of the menisci might lead to false-positive MRI findings and unnecessary surgery (43). Demographic aspects also play a part: there may be much more reason for a professional athlete to undergo soft tissue imaging in the acute phase compared with a middle-aged sedentary person (Fig. Few surgeons relish inter- vening in the acute phase when there is a lot of hemorrhage still masking the operative field. Although MRI may show many unexpected lesions in the acute phase, the immediate clinical management of the patient rarely changes (44). We identified four reviews summarizing the accuracy of MRI compared to arthroscopy for soft tissue knee injuries (11,15,16,45). All reviewed a wealth of evidence, albeit from methodologically weak studies in many instances. Of these studies, only four (14%) had adequate blind- ing of the index test (MRI) when conducting arthroscopy, the reference standard.

The pooled weighted sensitivity and specificity estimates from this review are reported in Table 15.

A book called Therapeutic Claims in Multiple Sclerosis (see Appendix 2) evaluates many therapies proposed for MS. It has to be said that the evaluation is from a very robust scientific point of view, the evaluations are decisive and usually dismissive on the grounds of lack of scientific evidence for effectiveness. Nevertheless, descriptions of the main aspects of the therapy are helpfully given. A book more sympathetic to the possibilities of CAM therapies in MS, but which is still based on rigorous evaluations, has been written by A. Bowling (Alternative Medicine and Multiple Sclerosis), and there is an associated website that may be helpful to people with MS (see Appendix 2). For another sympathetic view of the possible benefits of complementary medicine, you might try the Institute of Complementary Medicine (see Appendix 1), which adopts a very rigorous approach to the evaluation of such therapies, or the individual professional associations of the therapy concerned. This would also enable you to check the qualifications, experience and regulation of their members. Safety of complementary therapies Few complementary therapies have been fully scientifically evaluated, especially in relation to MS. Almost any therapy, scientifically evaluated or not, that has the power to produce very good and positive results, has the potential to do harm. Although complementary therapies are considered as ‘natural’ and, almost by association, to be intrinsically safe, this is not always the case. For example, some herbal medicines have to be very carefully targeted to symptoms and very sensitively administered, otherwise they may be harmful. Note that practitioners may expect initial ‘reactions’ or ‘aggravations’ or symptoms as part of the effective working of the therapy. A competent therapist should both warn you about these and what to do, if and when they occur. Finding a practitioner Finding a competent practitioner for a complementary therapy is not always easy. There is little statutory regulation for qualifications or practice for most of the therapies and therapists. However, the best ways of finding a practitioner are through: • an MS resource or therapy centre, where often other people with MS and staff in the centre will have experience of particular therapists; • a recommendation or referral from a neurologist, GP or other healthcare professional; • registers set up by the professional bodies of whichever therapy you are interested in; • referral for homeopathy to one of the NHS hospitals providing this service; • contacting the British Complementary Medicine Association, or the Institute of Complementary Medicine (see Appendix 1). Ask whether practitioners are trained and licensed; whether they are insured for malpractice, negligence or accident; and how complaints are handled. One of the key things is to try and ensure that whichever therapist you go to has a good understanding of MS. Costs involved Many complementary therapies (acupuncture and osteopathy to name only two) are increasingly recognized as having significant benefits and can, in certain circumstances and limited geographic areas, be made available through the NHS. The appropriate registration bodies can provide details of registered practitioners in your local area and provide guidance on how much you might expect to pay. You may find COMPLEMENTARY THERAPIES AND MS 35 the addresses of these registration bodies through the British Com- plementary Medicine Association or the Institute of Complementary Medicine (see Appendix 1). Some types of CAM therapy There are many, many types of CAM therapy that may be used by people with MS, most of which we cannot consider in detail here (see the book by Bowling for more detailed information on individual therapies in Appendix 2). Furthermore the popularity of such therapies in MS can change very rapidly, with new therapies or new variations of previously available therapies regularly appearing, and the use of others decreasing rapidly after only a brief high profile existence. Thus in this section we consider some of the key CAM therapies that appear to have gained longer term use, or appear to be on the verge of doing so.
