Combining an optimal PAIN dose of an NSAID with an opioid produces an addi- tive analgesic effect known as synergy that is greater In the American Pain Society’s March 2002 guide- than that obtained alone by doubling the dose of either lines for the management of pain in osteoarthritis, drug.

In 2002 there were 3 safe 100mg celecoxib,002 residents in 152 accredited ortho- paedic training programs purchase celecoxib 200mg mastercard. Up to two years are required in a general surgery or other approved medical or surgical residency buy 200 mg celecoxib mastercard. In 1980 the name of the specialty was changed to otolaryngology—head and neck surgery. The exceptions are eye disorders, which are treated by ophthalmologists, and brain disorders, which are treated by neurologists and neurosurgeons. Their specialty requires a range of skills because they treat a variety of problems both med- ically and surgically. Common conditions that otolaryngologists treat include hearing loss, tonsillitis, sinusitis, and head and neck cancers. Their surgical procedures are widely varied because they perform plastic surgery, delicate microsurgery, laser surgery, and major reconstructive procedures. Otolaryngologists can be in competition with other specialties for patients. The specialties of thoracic surgery, plastic surgery, allergy and immunology, and pulmonary medicine particularly overlap with theirs. Some otolaryngologists solve this by becoming super-specialists, specializing only in facial plastic surgery, for instance, or otology (relating to disorders of the ear). Otolaryngologists typically have fairly normal working hours and fewer emergencies than many other specialties experience. In 2002 there were 1,093 residents in 102 accredited training programs in otolaryngology, of whom 20 percent were female. One or two years of general surgery are required before entering an oto- laryngology training program, which takes three or four years to complete. Surgery and Surgical Specialties 61 Plastic Surgery While plastic surgeons are perhaps best known for their cosmetic work on aging movie stars, much of their work takes place outside the domain of vanity. Plastic surgeons help those born with defor- mities or burn victims regain a normal appearance. In addition to rhinoplasty for the nose and liposuction for the thighs, plastic sur- geons treat a variety of clinical disorders such as cancer, congenital deformities, skin lesions, facial trauma, and degenerative diseases. This is a highly creative field that requires a good aesthetic sense, attention to detail, and the ability to visualize and imagine. It is also a very innovative field with many new procedures on the horizon like artificial skin for burn patients and fat transfers.
Researchers should feel free to discuss their presentations with the media but should not offer more detail than they included in the presentation best celecoxib 100 mg. Fortunately trusted 100mg celecoxib, press reports are not usually regarded as breaches buy 100mg celecoxib with mastercard, as long as they do not contravene embargo regulations and as long as they are fairly general and do not include exact replicas of the tables or figures that you submit in your paper. It pays to be very conservative about where you publicise any early results. Despite the fact that the press often reports new findings from scientific meetings, any research results should be considered preliminary until the full report of the study undergoes peer review and is considered worthy of publication. For this reason, some journals have strict policies regarding prepublication of research results to overcome the conflict between the news media, who strive to publish any new information as quickly as possible, and the journal editors, who prefer to disseminate research information only after validation by peer review. Although journals have been 136 Review and editorial processes criticised for exerting too much control over the release of research results to the media, they go to great lengths to ensure the accuracy and validity of the information they publish. This policy, which is commonly known as the “Ingelfinger rule”, dates back to the 1960s. Franz Ingelfinger, who was the editor of the Lancet at that time, objected to papers being reported in the free press before they were published in the subscription based journal. The Ingelfinger rule, which covers embargoes on prepublication, has been adopted by many journals despite ongoing controversy about its influence on delaying the release of important research results to the public. In response, researchers may decide to withhold their full results at conferences where information is available to the media to ensure that their work is publishable. Many journals will place an embargo on your paper prior to publication and will include details of their embargo in your contract. In practice, an embargo limits prepublication publicity and protects both the authors and the publishers. In essence, the embargo allows you to prepare for the impact of the release of your results to the public and thus to avoid misinterpretation. When embargoes are broken, people who have a vested interest in the study results are not able to obtain the information that they expect and the researchers who plan to disseminate results in a careful and responsible manner are undermined. For example the BMJ lifts its embargo at 00·01 hours on Fridays and the JAMA typically holds its embargoes until 15·00 hours on the day before the cover date of the journal. Becoming a reviewer Serving as a reviewer or editor allows you to shape your field – publishing good work and keeping bad science out of the literature. McCabe and McCabe20 Once you have started publishing, it is fun to start reviewing. Although this honorary position rarely brings financial rewards, it is exciting to be invited to be an external reviewer by a journal. However, reviewing is a serious undertaking and can be time-consuming when done properly. In being a good reviewer, you need time to read the paper carefully from beginning to end, think about it, read it a second time, write a review, revise your review, and then check back with the paper again. The rewards for this are that you are sent the most current research work to read and that your reviewing skills have a currency that help to foster good science in the journals as well as your career.
