New York whereby they were constituted the Royal College of Surgeons in London and were empowered to examine candidates for the Membership. The sur- geons gave up Surgeons’ Hall and moved to a house in Lincoln’s Inn Fields. In 1806 Parliament granted £15,000 to the College to build a museum and 3 years later another grant of £12,500. By a charter of 1843 the title of the College was changed to the Royal College of Surgeons of England and the Fellowship of the College was instituted. This was achieved not by social gifts or personal attraction, but entirely by his scientiﬁc mind. When he started dissecting, 3 years only had passed since surgeons had ceased to be associated formally with the “art and mystery of barbers. In his quest for truth by William HUNTER observation and experiment he displayed a pene- trating vision, extending far beyond the horizon 1718–1783 of his own time. His country experimental station long anticipated “Down House,” which is now the William Hunter, John Hunter’s older brother, was experimental farm of the Royal College of born in rural Scotland. In 1846, he bound in the corpus of surgical doctrine and has began giving a series of lectures on surgery. Like Lister, he was interested in was an excellent speaker and became a very suc- the phenomena of inﬂammation and coagulation cessful teacher. He was an avid student of of the blood, but he was denied the use of a micro- anatomy and became the ﬁrst great teacher of scope and he little dreamt of a world of micro- anatomy in England. But his keen intellect noted and tution for teaching and studying anatomy on stressed mysterious variation in the reaction of Great Windmill Street in London. He gradually tissues to injury according to whether the skin shifted the emphasis of his practice from surgery was broken or unbroken.

His description of the cartilage antibiotics and little equipment, and the operating was far in advance of his time. The “subjects,” including the bodies hospital, he invented and developed the remark- of children, were procured largely through the able methods and equipment by which he became services of “resurrectionists,” that is grave known. The common disease of the joints in complex and infected fractures and to lengthen Hunter’s time was tuberculosis. His theory that bone would grow if observations deserves our admiration. His work was the beginning of a new medical paradigm, the con- servation and exploitation of the unlimited natural plasticity of bone. Ilizarov’s results were astonish- ing, his theory was contrary to orthodox views on bone regeneration. His reputation remained con- ﬁned to Siberia until 1967, when he successfully treated the Russian Olympic highjumper, Valery Brumel who, after a motorcycle accident, had chronically infected nonunited fractures of both legs, even after 14 operations by the best surgeons in Moscow. After treatment by Ilizarov, Brumel, completely healed, went on to jump again in competition. Dr Ilizarov’s years in a small wooden hospital with no research laboratory were over. It became known that he could straighten and lengthen a shattered or deformed leg and the Russian elite in need of orthopedic care journeyed to Kurgan.
He will be greatly missed by his many friends and colleagues all over the world—and not least by his patients proven amoxil 500mg antibiotics for uti birth control pills, especially the badly burnt Royal Air Force boys of the Second World War purchase amoxil 500mg with mastercard treatment for dogs cough, who banded together to form the Guinea Pig Club order genuine amoxil on line antibiotic wipes, which met annually at East Grinstead under his presidency. Archibald McIndoe died peacefully in his sleep Archibald Hector McINDOE from a coronary occlusion on April 12, 1960, at the age of 59. Later he came to London and joined his cousin, Sir Harold Gillies, the great pioneer of plastic surgery, who outlived him by a few months. Within a short time he was on the staff of St Bartholomew’s Hospital and his future in London was secure; indeed, for the last 20 years of his life, he was probably the most successful surgeon in any speciality in the metropolis. During the Second World War he was consultant in plastic surgery to the Royal Air Force. The writer became closely associated with him in the problems presented by burns combined with frac- tures, and in the management of patients with extensive skin and bone loss. This work, which George Kenneth McKEE started in Royal Air Force hospitals and at the Queen Victoria Hospital, East Grinstead, was 1906–1991 continued at the latter hospital until his death. On his election to the Council of the Royal Ken McKee, a pioneer of joint replacement College of Surgeons of England, he became surgery, was born at Ilford, Essex, the son of a intensely interested in the College, of which he medical practitioner who had migrated from had just ceased to be senior vice president when Northern Ireland at the turn of the century.

He was also a member and active participant in many orthopedic organiza- tions and on local hospital boards and staffs. On a rainy evening, October 13, 1959, when driving someone else’s car, he ran out of gas: while ﬁlling the tank, he was struck by another car and killed.

However amoxil 500 mg on-line virus kills kid, several recent reviews in the literature reveal little evidence of major differences between graduates from schools with a problem-based curriculum and those fromschools with a more traditional curriculum order amoxil line antibiotics for dogs canada. Whether this is actually true or reflects limitations of the indicators used to evaluate outcomes is unclear discount amoxil online visa antibiotics video. IMPLEMENTATING PROBLEM-BASED LEARNING Problem-based learning will have different implications if you are involved on a curriculum committee than if your involvement is as a tutor to a group of students undertaking a PBL exercise. In the former situation you will be engaged in reviewing the evidence for the effectiveness of PBL, in discussing the politics and practicalities of making such a major change to the curriculum, and in conducting or 111 arranging information sessions and workshops for the staff of the medical school in order to gain their support. Having decided in principle to proceed, your school may choose one of several implementation models (Figure 7. You may decide to convert the whole curriculum to PBL along the lines of the innovative schools of which McMaster University in Canada is the exemplar. Alternatively you may want to follow the path of schools such as New Mexico or Harvard and commence with two tracks, running the PBL track parallel to the conventional track with the advantage of gaining experience and undertaking com- parative evaluation. If you wish to be more cautious another alternative is to introduce PBL as a component of the curriculum or into individual courses with or without the expectation that the whole course will eventually change to PBL. COURSE DESIGN CONSIDERATIONS The basic principles of course design are the same as those in any other course (see Chapter 6). There is no single best way of approaching this task and it will be important to 112 ascertain which of the many styles of PBL you are expected to implement. In general,PBLcurricula are constructed in a modular format with blocks of several weeks being committed to a common theme (e. Factors to be taken into account will include: The major purposes of the module There are generally two major purposes to be achieved in a PBL module. One is the attainment of specific learning objectives in the form of an integrated knowledge and understanding of a defined problem (e. The other is skill in the process of problem-solving and self- directed learning. These are combined in various proportions in the Guided Discovery and Open Discovery approaches. In the Guided Discovery approach the emphasis is on both content and process. The course is carefully structured as a series of modules containing problems which direct students into learning the appropriate basic science and clinical content. While it is essential to allow the students to discover the learning issues from the problem, written guidelines are provided and tutor prompting occurs to ensure that all content areas are considered. The framework of the course and the problems may be the same as in the Guided Discovery approach but the students have much greater responsi- bility for determining what they should learn. The method of instruction PBL is usually conducted in small groups consisting of 5-10 students with a tutor. As a rule, the tutor is there to facilitate the process rather than to be a provider of content knowledge. In some schools tutors are deliberately chosen to be non-experts particularly where the Open Discovery approach is predominant. Small group activities are supported by independent study for which curriculum time must be carefully protected. Where tutor resources are limited it is possible to conduct PBL in large group 113 settings using student-led groups for discussion or by relying to a greater degree on independent study. We have used this approach successfully in a foundation course using PBL for first-year medical students (see later). The selection of the problems This is one of the most important considerations in course design. The problems must be of the kind that will ultimately be faced by the students after they graduate but must also be both broad enough and specific enough to engage the students in learning activities which match the curriculum objectives. In general they should be patient problems or health problems which will require students to go through the following process: Analysis of the problem. Identification of the multidisciplinary knowledge re- quired to understand and solve the problem. Obtaining agreement on when the learning tasks will be achieved, Application of the newly acquired knowledge to the initialproblem. While these problems will usually be represented in written form every chance should be taken to engage the students in the same PBL process with real problems encountered in the health care setting. To this end clinical teachers should be actively engaged in supporting the programme. This can be particularly helpful in the earlier parts of the curriculum where opportunities for clinical experience may be more limited. Your first task will be to obtain the objectives if they have been prepared by an overseeing group. Such objectives should define what it is the students should have achieved when they have completed the module (see Chapter 6). It is important to seek the involvement of teachers from all the disciplines that are expected to contribute to the learning outcome of the students. Once objectives are agreed, case summaries must be carefully prepared, remembering that they should be interesting and complex enough to engage students in the problem-solving process. A written guide should be developed for the tutors involved in the module, its content depending to some extent on the familiarity they are likely to have with the problem. Resource people who could be available for students to contact should be approached and times that meetings with students could be scheduled should be ascertained. Assessment This is one area where there is still considerable debate and development. It is important to involve all disciplines in the preparation of assessment materials as it is to engage them in defining the objectives. Only in this way will they be convinced that their discipline is being adequately represented. This reassurance is particularly important to the basic scientists who are often those most threatened by a change to PBL. Constantly challenging the students to evaluate the success of their learning is a vital role of the tutor. A way of approaching this is outlined in Chapter 8 in the section on self-assessment. Conventional knowledge-based tests, such as MCQs, should be avoided except perhaps for student self-assessment or progress testing. Unfortunately, test methods more suitable for PBL courses are not well developed. The Modified Essay Question may be the simplest and most flexible format if a written test of integrated knowledge is required (see Chapter 8). In many schools the tutor is asked to rate students on their performance with the emphasis being as much on their group and personal learning skills as on their grasp of the content. Few methods have been specifically designed to evaluate problem-based self-directed learning skills. The most well known of these is the Triple Jump Test developed at McMaster University. In the first step the student works through a theoretical problem on a one-to-one basis with a tutor, The student is asked to think aloud as the problem is assessed and learning needs determined.

A good therapist actually makes diagnoses and individualizes the treatment. One woman in her mid forties who has had rheumatoid arthri- tis for over two decades observed, Over the years I have learned how hard it is to ﬁnd physical thera- pists and exercise trainers who really understand how to put to- gether a realistic, comprehensive ﬁtness program for people with disabilities or limitations. Most professionals and programs are ori- ented toward people who are recovering from injuries that improve over time, not chronic problems that require a different approach or activity almost on a daily basis to prevent harm. Very few exercise programs are designed to address the problems that many people with disabilities have. Many pools have ladders that are very Physical and Occupational Therapy / 177 painful to use if you have trouble gripping things and problems with painful feet. The pounding and repetitive motion of aerobics and typical exercise programs are completely out of the realm of possi- bility. Exercise bicycles have been helpful for limited periods of time, but the need to switch activities to avoid over-stressing the same joints makes it difficult to develop a realistic, affordable program. Sally Ann Jones says she exercises “every morning before I get out of bed. Then I go stand up in the bathroom half-a-dozen times a day and move this stupid foot as many times as it will move. I dress myself; I do my own housework; I do everything I can do because that’s exercise. As soon as I get on the bike in the morning, hey, all the stiffness is gone. Certainly, chiropractic has long received professional recognition, but other alternative therapies still remain outside the Western medical mainstream, including herbal thera- pies, acupuncture, homeopathy, megavitamins, energy healing, prayer, massage, and faith healing. Roughly 40 percent of Americans say they use some type of alternative therapy, with numbers of visits exceeding en- counters with primary care physicians (Eisenberg et al. People with physical disabilities are much more likely than others to report using alternative therapies, especially to treat pain, depression, anxiety, insom- nia, and headache (Krauss et al. I asked every person whether they use or have used alternative or com- plementary therapies, such as acupuncture, chiropractic, herbal medicine, or massage. I’ve often wondered about acupuncture, but when I think of needles, I freeze up, and I don’t know many people who’ve used it. Walter Masterson has tried various alternative therapies: I’m getting massage now. A couple of years ago, the thought of seeing an acupuncturist would have been ludicrous to me. But at the end of the session, there was a sense of internal cleanness in my legs which impressed me. But when there’s no cure, it’s really impossible to say that something has no impact. I stopped going when it became apparent to me that it wasn’t going to make this go away. They tasted terrible, but I stuck with it for a couple of months just to see what impact it would have. Monkey arm, quite literally—probably about an inch and a half of monkey arm chopped up into ﬁve or six pieces. Lillian Lowell, in her late seventies, has a thick thatch of white hair and alert, inquisitive eyes. Her tiny house is neat as a pin, the living room ﬁlled with glass animals—cats, dogs, penguins. I started acupuncture shortly after I started hurting, and that worked beautifully for a year. It was very relaxing, very fun, and that kept me going for at least a year before I really thought of an op- eration. He told me it was os- teoarthritis and the cartilage was degenerating, the bones rubbing against each other—he described it fairly callously. My internist said, ‘Anything that’s good therapy for you is good therapy. She tried sev- Physical and Occupational Therapy / 179 eral practitioners, but “I wasn’t getting the same results from the acupunc- ture—the nice relaxed feeling. At that point, I realized I was starting to take over my own medical care. I was feeling guilty about going to see a chiropractor because it was an alternative medicine. So I didn’t even tell my primary care doctor”—the physician who had referred me to this woman. Some people try techniques, such as massage or prayer, they do not nec- essarily see as formal interventions. Lester Goodall is “still exploring the school where it’s mind over matter. I put my hands like this here,” Lester held both hands out straight in front of him, “and I try to communicate with my immune system. They now say the immune system,” which might affect MS, “is controlled by the brain. Wealthier people can afford to pay out-of-pocket for care, but costs accumulate over time. About 20 percent of people say they do not get physical or occupational therapy because they cannot afford it. Physical and occupational therapy were built into Medicare and Medicaid almost forty years ago, but with explicit limitations. Private coverage varies widely by plan, with insurers typically circumscribing the number and types of visits, setting strict limits. Insurers have only recently started paying for certain alternative therapies, primarily chiropractic. Esther Halpern feels that pool-based therapy is best for her painful back. The pool was nice and warm, and it’s much easier to do exercises in the pool. When they felt that I no longer needed it, I had to pay for it if I wanted water therapy. She was able to get herself dressed and undressed and—“ “I was able to get dressed and undressed by myself before that,” Esther interrupted. One day during my surgical rotation in medical school, my right leg suddenly collapsed, and the fall broke a small bone in my foot—the ﬁfth metatarsal. It precipitated a barrage of eerily identical questions:“Did you have a skiing accident? Taking the rope tow up the beginner slope, unsteady on rented skis, I felt an unpleasant choking sensation. The twisting rope tow had somehow latched onto the fringe of the scarf peeking out below my parka.
