Colon and rectal surgeons have one of the longest training pro- grams in medicine cheap 50mg silagra with visa. Completion of a five-year program in general surgery is a prerequisite to a one- or two-year residency in colon and rectal surgery generic silagra 50mg without prescription. There were only 60 residents active at 37 accred- ited training programs in 2002; 14 percent were women trusted silagra 100mg. Neurological Surgery Neurological surgery best 100 mg silagra, better known as neurosurgery buy silagra 100 mg lowest price, is the diagno- sis, evaluation, and treatment of disorders of the central, periph- eral, and autonomic nervous systems. Practitioners use high-tech equipment such as magnetic resonance imaging (MRI) to diagnose problems. They also meet with patients for regular physical exam- ination in the office. This can be a highly stressful and demanding specialty because it deals with the brain. The variation in outcomes is great; there are remarkable interventions and profound disappointments, as when a patient dies despite heroic intervention. The brain is a fascinating organ, and we are just beginning to understand its mysteries. Surgery and Surgical Specialties 57 The threat of malpractice is greater in neurosurgery than in some other specialties; as a result, insurance premiums are extremely high, as much as $300,000 a year in some states. The hours are long, and because neurosurgeons treat accidents and brain disorders that erupt suddenly, they may be called at any hour of the day. Because of the serious nature of the problems neurosurgeons deal with, prac- titioners get to know their patients well. Neurosurgeons treat brain and spinal cord cancers, hydrocephalus, lumbar and cervical disc disease, aneurysms, and head and spinal cord trauma. Neurosurgeons must be excellent problem solvers, and they must also understand the logic of anatomy, physiology, and integration of the nervous system. Neurosurgeons see a wide variety of conditions and serve a range of ages. They move between hospital visits, the operating room, and office settings. Neurosurgeons rank among the highest paid specialists, often earning more than $400,000 a year. In 2002 there were 778 residents at 94 accredited training pro- grams in neurosurgery. A year of a general surgery residency is required as well as a five- year residency in neurosurgery. Ophthalmology Ophthalmology is one of several surgical specialties without the word surgery in its title. Ophthalmology brings surgical, medical, and diagnostic prowess to the diseases and abnormalities of the eye. Because they work on such a small and delicate part of the body—the eye—ophthalmologists must possess excellent eye-hand coordination and technical skill. Ophthalmologists must be knowledgeable about optics, refraction, and visual physiology. While some of their patients are seen for only one procedure, ophthalmologists often have long-term relationships with patients who have vision problems. Because they face few life-and-death sit- uations, ophthalmologists deal very little with ethical issues like the right to die. Ophthalmologists spend time in office treatment as well as in the operating room. Ophthalmologists’ hours are much more controlled than are those in many other specialties. Annual average gross income ranges from $129,000 to $287,000, and liability insurance premiums are about average. There were 1,290 residents in 121 accredited training programs in ophthalmology in 2002. Ophthalmologists must have one year of general residency train- ing, followed by at least three years of an ophthalmology residency. Orthopaedic Surgery According to the American Board of Orthopaedic Surgeons: Orthopaedic surgery is the medical specialty that includes the preservation, investigation, and restoration of the form and func- tion of the extremities, spine, and associated structures by med- ical, surgical, and physical methods.

These are physiolog- Adolescents with scoliosis are therefore conspicu- ical variants with essentially no pathological significance. The lateral curvature develops as a result of common physiological variant, particularly in children. This is definitely the case with uncompensated dif- ferences of more than 2 cm. Whether it applies for differences of less than 2 cm is controversial, and it is possible that the leg length discrepancy only influ- ences the direction of the scoliosis rather than its development. Although the flat back is the esthetic ideal, the future prospects in terms of subsequent symptoms are much worse for the flat back than for a back with markedly sagittal curves, given the poorer shock-absorbing properties of the former. Lumbar disk damage occurs more frequently with this back shape and is also often associated with pain.

As part of the evolutionary development of hu- is delayed ossification of the lateral acetabular epiphysis, mans, the upright gait led to a widening of the iliac wing i. However, the dislocation itself very rarely occurs at in size while, at the same time, the birth canal became birth, but tends to occur secondarily during the course narrower. Humans solved this dilemma by bringing their of the first few months of life as a result of the increasing children into the world in a physiologically immature extension in the hip. To this immaturity can be added a number As the femoral head starts to be displaced from its of other factors: central position, this exerts pressure on the lateral ac- ▬ genetic, etabular epiphysis, causing ossification and growth to be ▬ hormonal and delayed. As the displacement progresses, the femoral head comes out of the acetabulum, usually in a cranio- dorsal direction. If the femoral head has left the acetabulum, shortening of the iliopsoas muscle will occur. The tendon, which is located right next to and partially fused with, the hip capsule, strangles the capsule and becomes an obstacle to reduction. The el- evated position of the femoral head causes shortening of the leg. At the same time, the abductors (particularly the gluteus medius and minimus muscles) and the hip exten- sors (gluteus maximus) are shortened and weakened. This leads, on the one hand, to a flexion contracture of the hip and, on the other, to the inability to stabilize the pelvis when standing on one leg. The consequence is an abnormal pelvic tilt that is compensated by hyperlordosis of the lumbar spine. If the ossification deficit is only slight, the displace- ment of the femoral head does not occur, and the ac- etabular dysplasia may heal up spontaneously during subsequent growth as the ossification catches up.

EXAMINATION ADMISSIBILITY REQUIREMENTS Part I Part I of the ABPMR’s certification examination is administered as computer-based testing (CBT) order silagra 100mg with mastercard. To be admissible to Part I of the Board certification examination purchase silagra 100 mg free shipping, candidates are required to complete at least 48 months of ACGME-accredited postgraduate residency training order 50mg silagra with mastercard, of which at least 36 months should be spent in supervised education and clinical practice in an ACGME-accredited PM&R residency training program discount 50 mg silagra with amex. Part II Part II of the ABPMR’s certification examination is administered as an oral examination generic 50 mg silagra otc. At least one full-time or equivalent year of PM&R clinical practice, PM&R-related clinical fel- lowship, or a combination of these activities is required after satisfactory completion of an accredited PM&R residency training program. The clinical practice must provide evidence of acceptable professional, ethical, and humanistic conduct attested to by two Board-certified physiatrists in the candidate’s local or regional area. In rare instances in which a physiatrist is not geographically available, two licensed physicians in the area may support the candidate’s application for Part II. Additional information about the certification and re-certification examinations are provided in several brochures published by the ABPMR. The brochures are titled Preparing for the Computer-Based ABPMR Examination, Computer-Based Testing Fact Sheet, and Preparing for the ABPMR Oral Examination. Part I Examination The Board made the decision to implement computerized testing for the Part I certification exam because they felt it offered many advantages to examinees. These include access and BOARD CERTIFICATION xxiii conveniences, enhanced security, and cutting-edge technology (e. Computer-based testing (CBT) is the administering of an exam using an electronic multiple- choice question format. The ABPMR transitioned from paper-and-pencil exams to CBTs with the May 2002 cer- tification exam. The Part I exam is administered on an electronic testing system that elimi- nates the use of paper and pencil exam booklets and answer sheets. Candidates use a keyboard or mouse to select answers to exam questions presented on the computer screen. The time remaining and the number of the question currently being answered are visible on the computer screen throughout the exam. Computer based testing provides simple, easy-to-follow instructions via a tutorial to complete the exam. The ABPMR uses a simple, proven computer interface that will require only routine mouse or cursor movements, and the use of the mouse or enter-key on the keyboard to record the option chosen to answer the question. Examinees have the option of using a brief tutorial on the computer prior to beginning the actual exam. Time spent with the tutorial does not reduce your testing time, so they recommend that examinees take advantage of it. The tuto- rial is available at the beginning of each section of the exam. It includes detailed instructions on taking the computerized exam and provides an opportunity to respond to practice ques- tions. You also become familiar with placement of information on the computer screen. The ABPMR’s computer-based exam is offered at over three hundred and fifty (350) technology centers located in most of the major cities throughout the United States and Canada through an arrangement with Prometric. Candidates should call to schedule their exam as soon as possible after they receive their admissibility letter from the Board. Candidates who wait too long to call may not be able to test at the location they prefer. However, in some regions due to large numbers of candidates, it will be first-come, first-served based on site capacity and numbers of sites in the area. Once you have received admissibility and authorization from the ABPMR, you may arrange for a test site location by calling Prometric Candidate Services Call Center. Prometric Technology Centers typi- cally consist of a waiting area, check-in area, and testing room with six to fifteen individual computer testing stations. One or more Prometric staff members will be on hand to check-in candidates and supervise the testing session. Prometric monitors exam sessions by several wall-mounted video cameras, as is noted by signage in each center. The exam is administered on one day annually at selected Prometric Technology Center sites throughout the United States and Canada. The exam is a 400-item test that is divided into a morning section consisting of 200 questions and an afternoon section composed of the remaining 200 questions.
