Photons passing through matter transfer their energy through the following three main processes: photoelectric absorption allergy pills and alcohol best buy prednisone, Compton scattering, and pair production (Figure 2. Photoelectric absorption In photoelectric absorption, the photon interacts with a bound inner shell electron in the atom of the absorbing medium and transfers its entire energy to the electron ejecting it from the occupied atomic shell. The incident photon disappears and the energy transferred is used to overcome the binding energy of the electron and the remainder appears as kinetic energy of the resulting photoelectron. Thus, the kinetic energy of the ejected photoelectron equals the energy of the incident photon minus the binding energy of the electron. The ejected photoelectron travels a certain distance within the absorber and loses its energy through secondary ionizations. In this way, the entire photon energy of the incident photon is deposited in the tissue irradiated. As a result, an atom that participated in photoelectric interaction is left ionized. The vacancy created due to ejection of the electron is instantly filled by an electron from an outer orbital of the same atom, emitting the balance of energy as a photon between the respective orbits with characteristic low energy. The photoelectric effect is the dominant energy transfer mechanism for X and fi ray photons having energies below 50 keV in biological tissues, but it is much less important at higher energies. Compton scattering the process of energy deposition called the Compton Effect occurs when the incident photon interacts with the outer orbital electron whose binding energy is very low compared with that of the incident photon. In this interaction, the incident photon transfers energy to an atomic electron causing its ejection from the atom. The photon is scattered with the remainder of the original energy in a different direction to that of the incident photon. Compton scatter thus causes ionization of the absorbing atom due to loss of an electron. The scattered electron (a secondary charged particle) travels some distance in matter and eventually loses energy by further ionization and excitation events to become part of the material. It is the principal absorption mechanism for X and fi rays in the intermediate energy range of 100 keV to 10 MeV. This range is in the therapeutic radiation range, and it also forms most of the fi radiation present in a nuclear explosion. The oppositedly charged particles are emitted in opposite directions to each other and cause damage as secondary charge particles. A positron is the anti-matter equivalent of an electron and it has the same mass as an electron, but it has a positive charge equal in strength to the negative charge of an electron. The energy of the interacting photon in excess of the equivalent rest mass of the two particles (1. The positron has a very short lifetime and, at the end of its range, it combines with a free electron. The entire mass of these two particles is then converted into two fi photons each of 0. The secondary electrons (or positrons) produced in any of these three processes frequently have enough energy to produce many further ionizations up to the end of their range. Dependence of absorption on atomic number the radiation energy deposition depends on the energy of the radiation and the atomic number (Z) of the absorbing material. The mass absorption coefficient of photoelectric absorption 3 varies directly with the third power of the atomic number of the absorber (Z). The effective atomic number of bone is about twice that of soft tissues, and the probability that a photon will be absorbed in bone is about six times that in an equal thickness of soft tissues. Bone is mainly comprised of calcium whereas soft tissues are comprised of low atomic number elements such as carbon, hydrogen and oxygen. On the other hand, the mass absorption coefficient for the Compton process is nearly independent of atomic number. Compton and photoelectric effects are vital for appropriate applications in Xray diagnosis and cancer therapy. In radiotherapy, high-energy photons in the range of 1-10 MeV are preferred because absorbed dose is nearly the same in bone and soft issues whereas low energy photons are preferred in diagnosis because of the much desired large contrast in absorption of these tissues. Half value layer When an electromagnetic radiation like X or fi rays passes through matter, its intensity is gradually reduced or attenuated with increasing depth due to the energy deposition interactions. This results in a decrease of photons, mainly due to photoelectric absorption and Compton scattering processes. The probability for absorption in a layer of material is proportional to the mass density. For a monoenergetic beam of photons, a constant fraction decreases as the beam travels through each unit of thickness in the absorber. This results in an exponential decrease in intensity with an increase in the thickness represented by the following equation; fix I (x) = I0 e where I (x) = the intensity at thickness x, I0 = is the initial intensity on the surface of the fi1 absorber, fi = nfifi is the absorption coefficient measured in cm, n = the number of atoms per 3 2 cm in the material, fi = the absorption cross section in cm, and x = the thickness of material in cm. Absorption of the beam depends on the mass and thickness of the absorber and the energy of the beam. Low energy photons are much more likely to be absorbed than high energy photons, for example the first 1. The probability that a photon will interact with an orbital electron is optimum when its energy equals the binding energy of electron in the encountered atom. In contrast, the total absorption coefficient of lead (atomic number 82) for fi rays, plotted against photon energy shows that the photoelectric effect dominates at low energies and pair production dominates above 5 MeV. The passage of charged particles, electrons and positively charged ions, causes intense damage (energy deposition) to molecules along the path in living tissue due to strong electrostatic interactions between the travelling particle and the electrons of the atoms of the medium. Charged elementary particles Protons with one unit mass and one positive charge, cause less damage than fi particles (helium nuclei) because the rate of deposition of energy varies inversely in proportion to the velocity of the particle and directly in proportion to the square of the charge. At the same energy, fi particles have lower velocity because of their higher mass and carry twice the charge of a proton. Radioactive materials often release fi particles and because they are a highly ionizing form of particulate radiation they usually have low penetration. They quickly lose their energy and they penetrate only a few tens of microns in body tissue. Beta particles (fi, electrons) are also emitted by radioactive nuclei, as well as being displaced from atoms and molecules by X and fi rays as discussed above. They carry a single negative charge but their path in absorbing materials such as tissue is erratic due to their light mass (approx 1/2000 that of a proton). High energy electrons ionize much less efficiently than fi particles because of their lower mass (and resulting higher velocity) and lower charge. Generally, beta particles do not penetrate further than the skin of the human body. Uncharged particles Neutrons (n) are uncharged particles with a mass very similar to that of a proton and are an indirectly ionizing radiation because without a charge they cannot participate in electrostatic interactions. At the same mass and energy, neutrons are more penetrating than are charged particles. Although neutrons do not interact strongly with electrons of atoms in the traversed material and do not directly ionize atoms, they do cause a density of ionization that is, far greater than in the case of X rays. Neutrons interact with the atomic nuclei of the medium and they lose energy by different interaction processes depending on their energy (velocity) and the mass of the encountered nucleus. In soft tissues, because of the abundance of protons with mass equal to that of neutrons, fast neutrons (>1 MeV) mostly lose energy by elastic scattering through collision processes producing high energy recoil protons, which in turn deposit energy by electrostatic interactions with electrons in the tissue as described above. Neutrons begin to interact by inelastic scattering at energies above 6 MeV, and fast neutrons may interact with carbon and oxygen nuclei producing fi particles, recoil protons and heavy nuclear particles. In reactors, typically heavy water, light water, or graphite are used to moderate neutrons. Thermal neutrons have a much larger effective cross-section than fast neutrons, and, therefore, can be absorbed more easily by any atomic nuclei with which they collide, creating a heavier and often unstable isotope of the irradiated element. Most fission reactors use a neutron moderator to slow down, or thermalize the neutrons that are emitted by nuclear fission so that they are more easily captured, causing further fission. This ability of neutrons to produce radioactive 19 nuclei (neutron activation) which then produce ionizing radiation by their decay can be used to analyse the atomic composition of certain materials. Ions the nuclei of carbon, neon, silicon, argon atoms form charged ions when one or more orbital electrons have been stripped off. These can be accelerated to hundreds of MeV energies in special accelerator facilities. High energy charged ions offer special advantages in cancer radiotherapy because of the energy distribution along their track which has a high peak at its end (the Bragg peak).

Hence, it is imperative to adequately compensate these professionals based on their qualifications and specialties. Despite a huge demand for services from this sector, allied and healthcare sciences is highly fragmented. Although it is estimated that there may be many more courses which are yet to be identified. Considering the lack of regulatory mechanism following 15 core professional groups (accounting for around 44 professions) has been enlisted below (The list is illustrative of the allied and healthcare professions. In future there may be addition or removal of certain professions based on the state of their regulation and standardization). It also needs a mention that most of these professions are not restricted to the professional groups under which they have been categorized, their role may extend to other professional services too. Similarly, the categorization is an indicative categorization, however this may evolve over time based on deeper understanding of the roles and responsibilities of each professional group: 1. Trauma Care Services the above mentioned groups account for over 44 job profiles in the allied and healthcare space, which are as followsA. The split up between theory and practical (bachelor level) proposed is as follows and accordingly the time available during the year could be allocated: st a. Student intake was recommended as one student for each 3-dialysis hemodialysis machines in the unit with a patient load of two shifts of dialysis per day.

Rupture of a hollow viscus or bleeding from a solid organ may produce few clinical signs allergy medicine for kids age 3 order prednisone online pills. Blunt trauma (generally leads to higher mortality rates than penetrating wounds) a. Missile wounds Key Objectives 2 In the emergency room a definitive diagnosis is seldom possible (especially with blunt trauma). Outline hemodynamic and other changes to be anticipated in a person with ongoing hidden blood loss. List physiologic considerations relevant to anemic patients important in deciding whether blood transfusion is indicated (degree to which oxygen delivery to tissues is adequate and compensatory mechanisms for maintaining oxygen delivery are overwhelmed or deleterious). Dog and cat bites account for about 1% of emergency visits, the majority in children. Insect bites in Canada most commonly cause a local inflammatory reaction that subsides within a few hours and is mostly a nuisance. In contrast, mosquitoes can transmit infectious disease to more than 700 million people in other geographic areas of the world. On the other hand, systemic reactions to insect bites are extremely rare compared with insect stings. The most common insects associated with systemic allergic reactions were blackflies, deerflies, and horseflies. Snake bites Key Objectives 2 Examine the patient completely to document the presence/absence of more than one wound. Detailed Objectives 2 Charter of Rights, statutes, regulations, by-laws, and the rulings of courts (the #common law#) are applicable in various ways to the practice of medicine and are binding on physicians. Physicians should consider potential medico-legal issues once treatment of patients with human bites (or animal) has been undertaken. Infection can complicate wounds received in fights/bites that can result in litigation involving both parties. Photographs of the injuries should be obtained at presentation and then throughout treatment. It may also be appropriate for the physicians to contact appropriate authorities such as law enforcement or employee health, depending upon the setting of the clash. Risk of blood-borne pathogen transmission should be analyzed and local regulations or laws should be consulted so that if appropriate, serologic screening of the individuals involved is undertaken. Individual case consideration should be made for screening all parties for serologic evidence of hepatitis B virus, hepatitis C virus, human immuno-deficiency virus, and syphilis. The physician may also be called upon to serve as an expert medical witness in the case. For example, hemodynamic stability takes precedence over fracture management, but an open fracture should be managed as soon as possible. On the other hand, management of many soft tissue injuries is facilitated by initial stabilization of bone or joint injury. Unexplained fractures in children should alert physicians to the possibility of abuse. Key Objectives 2 Reduce fracture so that normal alignment and length are restored and retain such reduction until healing occurs; encourage early restoration of function and continued rehabilitation. In either instance, emergency management becomes extremely important to the eventual outcome. Rib fracture Key Objectives 2 Since such patients frequently present in shock and/or respiratory distress, assess with urgency, resuscitate, and stabilize patient; suspicion of specific injury should lead to immediate diagnostic imaging/other investigative procedures. The incidence is uncertain, but likely it may occur several hundred times more frequently than drowning deaths (150,000/year worldwide). Hypothermia Key Objectives 2 Explain that the differentiation between salt and fresh water near drowning is more apparent than real since the amount of water needed to be inhaled for such differences to occur is more than five times the amount inhaled in near drowning (3-4 ml/Kg). Key Objectives 2 Assess and control vital functions (airway, breathing, and cardiovascular status) and give management priority to life threatening injuries. Definitive treatment of the facial trauma is relatively less urgent but of major cosmetic importance. The ultimate function of the hand depends upon the quality of the initial care, the severity of the original injury and rehabilitation. Damage to bones and/or joints Key Objectives 2 Demonstrate the assessment of hand injuries. Improved outcome after head trauma depends upon preventing deterioration and secondary brain injury. The law regarding delegation of care is specific to each province and the physician should be fully aware of local requirement in this regard. An intoxicated patient with a large head laceration, the result of a fall down a flight of stairs, is examined and then prepared for suturing prior to further investigation. The patient admits to being unconscious for a period of time, and does not remember much of what happened prior to the fall except a considerable amount of alcohol being consumed at a party. As you warn the patient that the administration of local anesthetic will cause some discomfort, the patient sits up and decides to go home. After explaining your concern about possible serious head injury, the patient replies that the risks are understood, repeats the risks verbally, and is willing to accept the risks. List the secondary effects and respective mechanisms that may lead to brain injury in addition to head trauma. Evaluation of these injuries is based on an accurate knowledge of the anatomy and function of the nerve(s) involved. Laceration Key Objectives 2 Identify the peripheral nerve involved, the level and type of involvement. Outline three mechanisms of nerve injury: traction injury, a direct blow or a percussive/contusion injury, nerve compression, and laceration or division. Since so many households include pets, dog and cat bites account for about 1% of emergency visits, the majority in children. Crush injuries (avulsions, bites, and crush injuries are usually "untidy" widespread tissue damage, severe or prolonged contamination) Key Objectives 2 Prior to wound closure, examine all patients thoroughly for evidence for injuries involving important underlying structures (tendon, nerve, vessel, foreign body). The average age at the time of spinal injury is approximately 35 years, and men are four times more likely to be injured than are women. The sequelae of such events are dire in terms of effect on patient, family, and community. Spontaneous epidural hematoma Key Objectives 2 Contrast the impairment of ventilatory muscle strength in complete or incomplete cervical spinal cord injury, and explain the effect of denervation of abdominal musculature. Define spinal cord injuries as either complete or incomplete (complete injury occurs when functional motor output and sensory feedback are absent below the spinal cord injury level, while some neurological activity persists below the site of injury in the case of an incomplete injury. Ventilatory muscles innervated below the level of a complete spinal cord injury are completely nonfunctional, while the degree of ventilatory muscle compromise is variable in patients with incomplete injuries). Explain that the extent of ventilatory muscle impairment depends upon the degree and location of the spinal cord injury. Explain that spinal cord injury affects ventilatory control in that individuals with tetraplegia have blunted perceptions of dyspnea and an abnormally small increase in ventilatory drive in response to hypercapnia (ventilatory response to hypercapnia among quadriplegics was approximately one-fourth that of normal controls).

20mg prednisone mastercard

A few days later he presents to the emergency room complaining of difficulty breathing allergy symptoms to eggs cheap 40 mg prednisone with mastercard. A 27-year-old woman presents to the clinic complaining of pain and discomfort on swallowing. A 34-year-old man presents to emergency room with headache and left-sided arm and leg weakness. A 23-year-old woman presents to the clinic for repeat assessment of wheezing symptoms and shortness of breath on exertion. A 45-year-old man is admitted to the hospital because of increasing shortness of breath and cough due to an asthma exacerbation. He is interested in avoiding any potential agents that might trigger his asthma in the future. Which of the following foods is most likely to precipitate an asthmatic reaction in this manfi Questions 21 through 23: For each patient with symptoms after taking a new medication, select the most likely mechanism. A 23-year-old man has a reaction after being given oral penicillin for a sore throat. A 23-year-old man has an exacerbation of asthma when he takes aspirin for a headache. The pain is located in his lower back and gluteal area, and is associated with morning stiffness that improves after several hours. On examination, he has limited forward flexion and tenderness of the ischial tuberosities. A 24-year-old woman has a facial skin lesion, thrombocytopenia, arthralgia, and pericarditis. Her laboratory tests reveal hyperglycemia and a mildly increased anion gap metabolic acidosis. She notices 1 hour of morning stiffness and swelling with redness in her wrists and hand joints. A 33-year-old policeman develops acute asymmetric arthritis involving his left knee and ankle and right ankle. Questions 31 through 36: For each patient with a medical condition, select the most likely immune dysfunction. X-rays reveal multiple lytic lesions and his serum protein electrophoresis has an IgG spike of 12 g/dL. Common signs and symptoms include fever, skin rash (urticarial or morbilliform), arthralgias, lymphadenopathy, and albuminuria. Immediate-type hypersensitivity reactions depend on the release of inflammatory mediators from mast cells either directly or through IgE-specific antibodies. These reactions occur with minutes of exposure to the drug, which rules them out in this patient. This is a reaction of T cells, which have been stimulated by antigen to react against infectious agents, grafts, and tumors. A classic example is the response to the tuberculin skin test in a person previously exposed to Mycobacterium tuberculosis organisms which occurs between 48 and 72 hours after antigen exposure. It is dependent on an IgE response controlled by T and B lymphocytes and activated when antigens interact with mast cell-bound IgE molecules. These patients have B-lymphocyte deficiency and bacterial infections and diarrhea. The course of the hemoptysis is variable, but renal involvement is often progressive. Current therapy includes intensive plasma exchange, cytotoxic agents, and gluco-corticoids. Immune complexes with normal complement levels are found in IgA nephropathy and Henoch-Schonlein purpura. No single measurement of immune function correlates well with clinical efficacy, suggesting a complex of effects that likely includes a reduction in T-cell cytokine production. This type of therapy is reserved for clearly seasonal diseases that cannot be adequately managed with drugs. Serum IgA levels are a good screening test for agammaglobulinemia, and the nitroblue tetrazolium assay is useful to detect killing defects of phagocyte cells. Although it can involve any epidermal or mucosal surface, the palms and soles are usually spared. This represents a case of generalized heat urticaria or cholinergic urticaria rather than exercise-induced urticaria. The latter is characterized by larger lesions and possible anaphylactic reactions and is not triggered by hot showers. Although thought to be cholinergically mediated, atropine does not block symptoms in generalized heat urticaria. Because anaphylaxis does not occur and hydroxyzine is so effective, hot showers are not a great danger. Angioedema is often not itchy and, like urticaria, is transient; manifestation peaks in minutes to hours and disappears over hours to days. Anaphylaxis is characterized by an initial exposure followed by the formation of specific IgE antibody. Repeat exposure results in antigen combining with IgE bound to basophils and mast cells and subsequent degranulation. Anaphylactoid reactions, such as those to radiographic contrast media, are generally not immunemediated and do not require prior exposure. Impaired soluble antigen recognition by T lymphocytes can occur when absolute counts are still normal. Macrophages are felt to be particularly important in carrying the virus across the blood-brain barrier. Circulating immune complexes might help explain arthralgias, myalgias, renal disease, and vasculitis that occur in infected individuals. The symptoms develop characteristically over days and global brain dysfunction is common. Lymphoma presents with one or relatively few irregular weakly enhancing lesions more commonly in the periventricular area. A following subacute phase has been described that can lead to late complications. The presence of inflammation in the airways has resulted in increased usage of inhaled corticosteroids for maintenance therapy. Other sulfitecontaining foods include fresh fruits, potatoes, shellfish, and wine. Aspirin, tartrazine (a coloring agent), and beta-adrenergic agonists also commonly provoke asthmatic attacks. Skin tests are reliable in predicting low risk (similar to general population) for those claiming previous penicillin reactions, and desensitization is feasible. The frequency of reactions to cephalosporins in penicillin-allergic patients is not definitely known. It is thought that reactions may be more common in women, Blacks, and those with idiopathic angioedema. This is probably a pseudoallergic reaction related to inhibition of cyclooxygenase with a resultant enhancement of leukotriene synthesis or effect.

In most cases, it is mild and self-limited, but the potential for hypovolemia (reduced effective arterial/extracellular volume) and dehydration (water loss in excess of solute) leading to electrolyte abnormalities is great. Contrast the effect of the two different types of diarrhea on electrolyte concentration and volume status if volume of diarrheal fluid lost is identical. Monocular diplopia is almost always indicative of relatively benign optical problems whereas binocular diplopia is due to ocular misalignment. Once restrictive disease or myasthenia gravis is excluded, the major cause of binocular diplopia is a cranial nerve lesion. Careful clinical assessment will enable diagnosis in most, and suggest appropriate investigation and management. Inter-nuclear ophthalmoplegia (multiple sclerosis, brain stem infarction) (In children consider post-viral inflammation, brain stem tumor) b. Fracture of orbital floor Key Objectives 2 Determine whether the condition of monocular diplopia is present or the diplopia is binocular (resolves with occlusion of vision to either eye). If a motor vehicle accident occurs, the physician who diagnosed diplopia may be legally liable if both the patient and/or the motor vehicles branch (provincial statutes vary) were not advised that driving is not permitted (until the diplopia is reversed, if possible). Physicians who diagnose diplopia are required to advise both the patient and/or the motor vehicles branch (provincial statutes vary) that driving is not permitted unless the diplopia is reversed. Three pairs of extra-ocular muscles move each eye in three directions: vertically, horizontally, and torsionally. Identify the parasympathetic fibers that run with the 3rd nerve as responsible for pupillary function that is affected by lesions compressing this nerve. Syncope/Presyncope 10% Key Objectives 2 Determine whether patients complaining of dizziness have true vertigo (an illusion of motion, self or environment, arising from asymmetry of the vestibular system, that is episodic, never continuous, provoked by head position change without decreasing blood pressure). In such circumstances, the important role of the physician is to alleviate any suffering by the patient and to provide comfort and compassion to both patient and family. Key Objectives 2 When caring for a dying patient, physicians must formulate a plan of management that ensures adequate control of pain, maintenance of human dignity, and avoids isolation of patients from their family. Ethicists have considered the treatment of pain for a dying patient, and consensus has been reached that pain management at the end of life is the right of the patient and the duty of the clinician. The possibility of increased uncontrolled pain at the end of life is indeed an emergency. Such pain, if not brought under control, can be devastating to patient and family. Physicians may have an inflated perception of the risk of hastening death by treating pain with opioids. As a consequence, they may fail to treat pain effectively because of concern with violating ethical and moral standards. Distinguish between pain management for intractable symptoms and physician-assisted suicide. There is a need for physicians to balance such concerns with their moral obligation to treat pain in the suffering patient. Appropriate treatment of pain is morally acceptable even if it hastens the death of a patient as long as there was no intention to do so by the physician (principle of double effect). The bioethical principle of double effect is important to patients and to physicians who care for such individuals. As Quill states, "To the extent that the principle allows patients, families, and clinicians to respond in an ethically and clinically responsible way to palliative care emergencies without violating the fundamental values of any of the participants, the principle of double effect should be used and protected". Administration of pain medication to a dying patient does not violate legal tenets. Distinguish between pain management for persistent symptoms and physician-assisted suicide. Balance such concerns with the legal obligation to treat pain in the suffering patient. Prescribe pain medication for physical, spiritual, and psychological suffering in a dying patient. While this may carry a small risk of hastening death, if it is not the intention of the treating physician, but it is intended to treat pain or relieve discomfort, it is legal. Euthanasia requires a physician to physically administer a medication with the intent of causing death. Alleviate suffering in a patient enduring a terminal illness and experiencing pain even to the point of causing unconsciousness and hastening death. Indeed, there may be a legal risk to clinicians that do not treat pain effectively. In summary, the treatment of pain is legally acceptable even if it hastens the death of a patient as long as there was no intention to do so by the physician (principle of double effect). Principle of double effect and end-of-life pain management: additional myths and a limited role. Progressive (scleroderma, achalasia) Key Objectives 2 Contrast difficulty initiating swallowing (coughing, choking, nasal regurgitation), from food sticking after being swallowed, then dysphagia involving only solid food from dysphagia of both solid and liquid food, and whether intermittent or progressive. Outline the three phases of normal swallowing (oral preparatory, pharyngeal, esophageal), their timing and co-ordination, and role of the swallowing center within the central nervous system. Assessment of the manner dyspnea is described by patients suggests that their description may provide insight into the underlying pathophysiology of the disease. Other (anemia, anxiety, carbon monoxide) Key Objectives 2 Differentiate true dyspnea from tachypnea, hyperpnea, and hyperventilation. Outline how respiration is controlled, how gas is exchanged and transported, and the consequences at the level of cellular respiration. Attention to clinical information and consideration of these conditions can lead to an accurate diagnosis. Diagnosis permits initiation of therapy that can limit associated morbidity and mortality. Outline how the respiratory system is designed to maintain homeostasis regarding adequate oxygenation and acid-base status. Include oxygenation derangement as well acidemia and hypercapnia as causes of dyspnea in addition to stimulation of mechano-receptors throughout the upper airway, lungs, and chest wall. Identify chemoreceptors in the carotid bodies and aortic arch that sense partial pressure of oxygen in arterial blood and are also stimulated by acidemia and hypercapnia as well as central chemoreceptors in the medulla as causing dyspnea even in the absence of activation of respiratory muscles. Usually patients have cardio-pulmonary disease, but symptoms may be out of proportion to the demonstrable impairment. Other (diaphragmatic hernia, massive ascites, severe scoliosis) Key Objectives 2 For correct assessment, consider the respiratory rate in the context of age of the child (neonates normally breathe 35-50 times per minute, infants 30-40, elementary school children 20-30, and preadolescents 12-20) and observe the quality of the breathing. In febrile young children, who most frequently are affected by ear infections, if unable to describe the pain, a good otologic exam is crucial. Infections (sinusitis, adenitis, dental/pharyngeal/peritonsillar abscess, parotitis) b. Other (thyroiditis, cervical spine disease, temporo-mandibular joint dysfunction, wisdom teeth, migraine, trauma, neoplasms) Key Objectives 2 Perform careful examination of the head and neck and upper aero-digestive tract, including the jaw, parotids and thyroid for referred pain, as well as ears (use tuning fork), cervical lymphatics, and mastoid areas. On closer scrutiny, such swelling often represents expansion of the interstitial fluid volume. At times the swelling may be caused by relatively benign conditions, but at times serious underlying diseases may be present.

These Objectives do not define a medical curriculum and should be used to identify the domains of cognitive and clinical skills evaluated by this national examination allergy symptoms feel like flu buy prednisone 40mg without a prescription. Baumber, then as Chair of the Education Committee, and a group of co-authors from the University of Calgary, were involved in upgrading the examination and the development of the first edition of the Objectives. The second edition was the result of revisions undertaken by a Task Force in 1997-98. Now in 2003, we publish the third edition, following a major collaborative effort involving the faculties of medicine, public members of Council, panels of practicing physicians, all headed by Dr. However, this edition will be web based, with better indexing, making for easier use. Although several significant steps beyond the 1999 edition of these objectives have been accomplished, it is a certainty that the next edition will provide additional improvements. Perhaps since perfection may never be attained, it is more advantageous that each edition be an advance on the previous one. We hope that this format will enable readers to locate the required set of objectives with greater ease. One of the recommendations made by physicians from across Canada who reviewed the second edition was to translate and apply the generic objectives in the Legal, Ethical and Organizational domains of medicine to actual clinical situations. In the current edition, we selected a number of appropriate clinical presentations and after referring to the generic Legal, Ethical, and Organizational objective, applied these to the specific presentation. No attempt was made to translate all of the generic objectives to all of the clinical presentations. It was considered desirable to provide a number of examples without attempting to be comprehensive. In the belief that a true understanding of clinical situations requires in many instances the application of scientific concepts that underpin clinical medicine, an attempt was made to identify such concepts. These concepts are included in the hope that they will assist candidates with their comprehension of the various clinical presentations. If readers indicate that this listing of scientific concepts is valuable, a concerted effort will be made to ensure a more comprehensive list with the next edition. Most important, this section is not included for the purpose of creating a separate set of examination questions, but rather to make the reader aware of some of the Applied Scientific Concepts that are relevant to a given clinical presentation. Those readers who count the number of clinical presentations in the current edition may be surprised to discover that the number appears to have contracted. What is being observed is not a contraction but a re-organization of the clinical presentations. The human body continues to react to an infinite number of insults in a finite number of ways, and the present edition, by identifying all of these ways, continues to define the domain of medical knowledge in a comprehensive manner. The Table of Contents is organized by clinical presentation, but the search engine should provide the best assistance. The objectives have been updated, extended, and the format used for each presentation has been changed in a minor fashion. The Rationale provides an overview of why facets of the problem are critical for the competent physician by highlighting fundamental, vital issues. The Causal Conditions or Diseases leading to the clinical presentation are the next category. The manner in which the conditions are organized was carefully considered, and in so far as possible a logical scheme was selected. The Key Objective(s) proposes to emphasize the one or two elements of the clinical presentation that are essential to the successful management of the problem. The fourth and last category, the Objectives, is intended to stress those elements of the data gathering, diagnostic process and management that are central to the specific presentation. This separation was completed in recognition of the fact that some of the legal, ethical, and organizational objectives are learned best during graduate clinical education. As before, some of the objectives that emphasize management also are likely to be achieved after a period of post-graduate clinical experience. The objectives have been defined in behavioral terms, and are intended to reflect our expectations of competent physicians in the supervised practice of medicine. They are written for those who have the task of writing evaluation questions for the purpose of certifying basic medical competence as well as for candidates being examined. The authors gave careful consideration to the choice and meaning of verbs used to define the behaviors expected within the various objectives. The assumption has been made that it is better to prevent than treat, and that rational treatment is possible only after a diagnosis has been established. The Objectives deal with data gathering, diagnostic clinical problem solving, and the principles of management which are applicable, in part or in whole, to clinical situations faced by physicians. The section of Population Health and Its Determinants, has been separated into a clinical presentation relevant to the practice of medicine that addresses the needs of populations rather than individuals. The Pediatric Objectives stress health maintenance and disease prevention through an understanding of the complexity of the process of growth and maturation from infancy to adulthood. Physicians caring for children become their advocates at all interfaces of the child with society and must work comfortably with many other health professionals to achieve these goals. There are, however, many childhood diseases that present unique challenges to the physician in terms of diagnosis and management. Where appropriate, selected clinical presentations have been separated into adult and pediatric sections. In addition to the remarkable contribution made by the authors of this Third Edition, I am most appreciative of the comments and suggestions made by many physicians from across Canada, the representatives of 12 licensing authorities and the two national certifying bodies, as well as, the Associate Deans and faculty members of all sixteen medical schools. Frequently, the social, cultural and behavioral characteristics of the patient may make it challenging to obtain the clinical data. However, the candidate must be able to implement timely and appropriate plans for investigation and management based on the information obtained. Objectives Faced by a patient with a clinical problem, candidates will: 2 Obtain pertinent information about the patient. Communication Skills Competent candidates will communicate effectively with patients, families, and other relevant persons by: 2 Demonstrating a compassionate interest, respect, and understanding of the patient as an individual, while maintaining a professional relationship. Investigations Competent candidates will: 2 Select and interpret appropriate laboratory and other diagnostic procedures that confirm the diagnosis; exclude other important diagnoses or determine the degree of dysfunction. Clinical Judgement And Decision-Making Competent candidates will: 2 Differentiate between important and spurious information. Health Promotion And Maintenance Competent candidates will: 2 Formulate preventive measures into their management strategies. Critical Appraisal/Medical Economics Competent candidates will: 2 Evaluate medical evidence in both clinical and academic situations. Law and Ethics Competent candidates will: 2 Discuss the principles of law, biomedical ethics and other social aspects related to common practice situations. Ogilvie syndrome (trauma/surgery, medical illness/drugs, retroperitoneal hemorrhage) ii. Explain that normal intestinal motor function is controlled by the extrinsic nerve supply (brain and spinal cord), the enteric brain (plexi within wall of intestine), and local transmitters (amines and peptides) that excite smooth muscles.
