Once the effects of the digoxin have worn off and a rate-controlling drug is required for her atrial fibrillation then one of these two agents may be considered rather than digoxin given her chronic kidney disease allergy medicine homeopathy cheap claritin 10mg on line. Often allergy symptoms skin discount 10 mg claritin amex, very low amounts of energy during cardioversion will convert atrial flutter allergy vs intolerance order claritin 10 mg without a prescription. Atrial flutter typically originates from the right atrium and most often involves a large circuit that travels around the area of the tricuspid valve nut allergy treatment uk buy claritin without prescription. Less commonly allergy shots bc discount claritin 10 mg with amex, atrial flutter can result from circuits in other areas of the right or left atrium allergy testing oklahoma order 10 mg claritin overnight delivery. Atrial flutter is characterized by regular atrial activation with an atrial rate of >240 beats/min. Retention of fluid is complex and not due to any one factor; however, hormones may contribute. The exact mechanisms that initiate renal conservation of salt and water are not precisely understood, but may include arterial volume receptors sensing a decrease in the effective arterial blood volume that occurs in heart failure. The poor prognosis associated with these aneurysms is due to the associated left ventricular dysfunction, rather than to the aneurysm itself. In aortic stenosis, there is normal or increased overall cardiac size, and dilatation of the proximal ascending aorta, not stenosis. Besides coarctation of the aorta, aortic occlusive disease, dissection of the aorta, and abdominal aneurysm may lead to differential blood pressure in arms and legs. The other answers listed will not result in the clinical findings described in this patient. These changes are the result of the activation of the renin-angiotensin-aldosterone system. Thyroid disease may affect the heart muscle directly or there may be excessive sympathetic stimulation. Common symptoms of thyrotoxic heart disease include palpitations, exertional dyspnea, and worsening angina. Pericardial effusion, and aortic insufficiency are not usual finding in thyrotoxicosis, and the cardiac output is increased in hyperthyroidism, not decreased. Since the duration of atrial fibrillation is not known, it is presumed to be chronic. Aspirin is only modestly effective in reducing cardioembolic events and not the first choice. Earlier manifestations of arteriosclerosis include thickening of the retinal vessel wall. Tendon xanthomas and xanthelasma are not seen in patients with diabetes, myxedema, or chronic kidney disease unless they have concomitant familial hyperlipidemia. While small effusions are common, tamponade is unusual, as are heart failure and constriction. Other diseases causing pericarditis should be searched for, and may influence the prognosis. Management includes avoidance of precipitating factors, simple adaptive maneuvers, volume expansion, and pharmacologic agents. While thyrotoxicosis, volume depletion from diuretic therapy and venous varicosities can result in a postural drop in blood pressure, the autonomic response will cause an increase in heart rate. General physical examination may reveal scoliosis, pectus excavatum, straightened thoracic spine, or narrow anteroposterior diameter of chest. The classic findings of cardiac tamponade include arterial hypotension and pulsus paradoxus. Rupture of a chordae tendineae can lead to acute mitral regurgitation and pulmonary edema, but the absence of a holosystolic murmur makes this unlikely. Normal ejection fraction and aortic sclerosis rule out either systolic or valvular heart disease as causes. Vasculitis is a very rare and unusual cause of coronary ischemia and therefore unlikely. The other organisms are seen less frequently in late prosthetic valve endocarditis. Her positive family history of hypertension also makes essential hypertension the most likely diagnosis in her. Stimulation of the rennin-aldosterone system in renal artery stenosis will cause similar biochemical changes in the electrolytes. There is a reverse 3 deformity of the esophagus, the belly of which represents the dilated aorta after the coarctation. The border of the descending aorta shows a medial indentation called the 3 or tuck sign, the belly of the 3 representing the poststenotic dilation and the upper portion by the dilated subclavian artery and small transverse aortic arch. The presence of calcification in the ventricular wall and the abnormal left ventricular contour alerts one to the consideration of a ventricular aneurysm. Flutter waves, regular ventricular rate at 150/min make the diagnosis of atrial flutter, rather than atrial fibrillation, sinus tachycardia, or ectopic atrial tachycardia. In third-degree heart block there is no relationship between the atrial and ventricular rate. These nonspecific abnormalities do not indicate significant coronary heart disease, especially in a young patient with no cardiovascular risk factors. This type of T wave is characteristic of hyperkalemia, as is the absence of visible atrial activity. There is a bimodal distribution in the population, with the first peak before 6 months of age (sudden infant death syndrome). The most common coronary artery finding is extensive chronic coronary atherosclerosis, although acute syndromes do occur. Primary right ventricular failure is characterized by a disproportionately high right atrial pressure with normal or high wedge pressure. The cardiac output is usually low and systemic vascular resistance is usually normal or increased. The apex is usually hyperdynamic but actual forward stroke volume is usually diminished. Despite this they improve survival in patients with left ventricular dysfunction and heart failure. Beta-blockers, Ca + calcium channel blockers, and digoxin are drugs commonly used. Lung transplants have provided a major therapeutic modality for managing severe pulmonary hypertension. It occurs in patients with very low stroke volume, especially dilated cardiomyopathy (Fauci, Chapter 220) 87. In aortic regurgitation, the bisferiens pulse can occur both in the presence or absence of aortic stenosis. When tricuspid regurgitation becomes severe, the combination of a prominent v wave and obliteration of the x descent results in a single, large, positive systolic wave. After release of the Valsalva maneuver, right-sided murmurs tend to return to baseline more rapidly. It can also be found in pure aortic regurgitation or combined aortic regurgitation and aortic stenosis. The maneuver of inflating bilateral blood pressure cuffs will increase the murmurs of mitral regurgitation, ventricular septal defect, and aortic regurgitation. The presence of a positive Kussmaul sign helps differentiate the syndrome from cor pulmonale and restrictive cardiomyopathies. Physical examination reveals a pulsus paradoxus (>10 mm Hg inspiratory decline in systolic arterial pressure), a prominent x descent of the jugular veins, but no Kussmaul sign. Fibrous plaques are found on the endothelium of the cardiac chambers, valves, and great vessels. These plaques can distort cardiac valves; tricuspid regurgitation and pulmonic stenosis are the most common valvular problems. Palpitations, atrial fibrillation, hypertension, angina, and heart failure are more common cardiac manifestations of hyperthyroidism. Histology reveals increased collagen, glycoprotein, triglycerides, and cholesterol in the myocardial interstitium. Therefore, diabetes is now considered a coronary heart disease equivalent when assessing risk even if the patient has not had any previous cardiac symptoms. For all individuals at increased risk, lifestyle modification is stressed as a key component therapy. This evidence comes from the analysis of cardiovascular statin trials that have a lower rate of ischemic strokes in patients taking the medication as compared to the placebo group. In addition, lifestyle modification is important for this individual, especially smoking cessation. Recently, two large randomized clinical trials have shown no benefit with estrogen replacement in postmenopausal women as a means of reducing cardiovascular risk. With this evidence, estrogen replacement is not recommended for cardiac risk modification, and is only indicated to treat the symptoms of menopause. For postmenopausal women at increased risk of cardiac disease, statins are considered first-line therapy in modifying risk since there are randomized trial data from multiple trials supporting their effectiveness in women. Since this patient has only one risk factor, her future 10-year risk is low (<10%) and lifestyle modification is the best advice. The goal for blood pressure control in diabetics is set at 130/80 mm Hg which is lower than in nondiabetics. This lower pressure is important in preventing progression of renal disease and other end-organ damage. Their adverse metabolic consequences include renal potassium loss leading to hypokalemia, hyperuricemia from uric acid retention, carbohydrate intolerance, and hyperlipidemia. Treatment of isolated systolic hypertension with low-dose thiazides results in lower stroke rates and death. Questions 1 and 2: For each patient with a skin lesion, select the most likely diagnosis. The lesions appear as sharply marginated erythematous papules with silvery-white scales. They are palpable, firm, and appear violaceous with some nodules appearing purple brownish. Questions 3 through 5: For each patient, select the associated skin and clinical findings. A 22-year-old man is diagnosed with psoriasis, and has never received any treatment. A 43-year-old woman develops a rash on her arms and hands after starting a new job in a factory. The lesions have well-demarcated erythema and edema with superimposed closely spaced vesicles and papules. A 19-year-old woman with asthma has a chronic rash with distribution on her hands, neck, and elbow creases. A 85-year-old woman has large blistering lesions on the abdomen and thighs that come and go 8. She has noticed 10 lb weight loss over the past 3 months with heartburn and early satiety. A 22-year-old woman develops an acute contact dermatitis to a household-cleaning agent. Which of the following treatments is most appropriate during the bullous, oozing stagefi Which of the following is a characteristic of ringworm of the scalp as compared with other dermatophytosesfi On examination, there are large tense, serous-filled bullae on the affected areas. A 27-year-old woman has a 1-year history of loosely formed bowel movements associated with some blood and abdominal pain. The rash is on both cheeks, and it is red and flushed in appearance, with some telangiectatica and small papules. A 70-year-old man develops multiple pruritic skin lesions and bullae mostly in the axillae and around the medial aspects of his groin and thighs. There are some lesions on his forearms and on his lower legs (first appeared in this location), and moderately painful oral lesions. Questions 22 and 23: For each patient with a skin lesion, select the most common associated features. Questions 24 through 28: Match the following descriptions with the correct diagnosis. On examination, she has multiple inflammatory papules on her face, with some even larger nodules and cysts. A 70-year-old man comes to the emergency department because of a skin rash and severe itching. He appears ill; there is a generalized skin rash that is scaly, erythematous, and thickened. A 32-year-old woman comes to the emergency department because of a generalized erythematous skin rash.

Review of the chapter on sensitivity analysis will indicate the impact of this uncertainty on the final estimate allergy medicine like benadryl cheap claritin 10mg with mastercard. Results and Sensitivity Analyses In the radiotherapy utilisation tree allergy treatment for babies purchase claritin 10 mg otc, a total of 415 branches were constructed for all the cancers that represented 1% or greater of the entire registrablecancer population best allergy medicine for 3 year old buy discount claritin 10mg line. The branches that ended with the recommendation for radiotherapy numbered 250 and a further 165 branches ended with no radiotherapy being recommended allergy medicine 19 month old cheap 10 mg claritin visa. In terms of peer review allergy testing center purchase claritin 10mg on line, drafts of each of the chapters were sent to the designated expert reviewers allergy on eyelid discount 10mg claritin otc. This comprised 15 National Cancer Control Initiative steering committee members and 91 expert reviewers. Reviewers who were specialised in one or two particular tumour sites were sent only the relevant chapters. General radiation oncology, medical oncology, surgery, palliative care and nursing reviewers were sent all chapters to comment on. Some reviewers who felt that they were not sufficiently expert enough in a particular area often indicated that they had passed the responsibility on to an expert within their department or specialty. Forty-two of the reviewers provided comments, with 43% of reviewers being from a non-radiation oncology specialty. This resulted in 139 changes to the text, trees, epidemiological data or evidence cited including a number of offers of additional epidemiological data. The review also resulted in 2 major reconstructions of the radiotherapy utilisation trees for 2 tumour sites. The radiotherapy branches that represented the greatest proportion of cancer patients receiving radiation were early breast cancer treated by breast conserving surgery and post-operative radiotherapy (8% of all cancer diagnoses), preor post-operative radiotherapy for T3-4 or N2-3 rectal cancer (1%), early prostate cancer (2%) and metastatic prostate cancer (2%). In addition, there were many branches that ended in radiotherapy being recommended for symptom control for Non Small Cell Lung Cancer (3-6%). These data are based on the estimates most likely to be closest to the real value for each of the variables within the tree. As the table shows, the overall proportion of patients who would receive radiotherapy in an optimal situation based upon the evidence available is 52. The optimal radiotherapy utilisation rates in Table 1 vary from a low rate of 0% for liver cancer patients to a high of 92% of Central Nervous System tumour patients recommended to have radiotherapy during the course of their illness. Data Uncertainty As indicated in many of the chapters on specific tumour sites, there were variables for which there was significant uncertainty. Typically these were near the terminal ends of the trees where large studies on prevalence rates were lacking, 2. Uncertainty in the choice of radiotherapy between treatment options of approximately equal efficacy such as surgery, observation or radiotherapy for localised prostate cancer. The uncertain variables are listed under each of the three types of uncertainty along with the range of values applied in the sensitivity analyses. The methodology, differences between the analyses and the results are described below. One-way sensitivity analysis allows an assessment or estimate to be made of the impact of varying the value of one of the branches of the tree on the overall radiotherapy utilisation estimate. This was done by setting upper and lower data limits and modelling the radiotherapy utilisation tree using these extreme values. One-way sensitivity analyses were described in each of the tumour-specific chapters and have been aggregated here as a tornado diagram. A tornado diagram is a set of one-way sensitivity analyses brought together in a single graph. Further details on the description and interpretations of tornado diagrams can be found in the section on materials and methods. The tornado diagrams for each of the individual tumour sites can be found in the relevant chapters. Each bar represents a single one-way sensitivity analysis and the legend provides details of each of the analyses depicted. The variables are ranked on their effect on the overall radiotherapy utilisation estimate with the variables that have most impact appearing at the top of the graph and those with smaller impact appearing below. The model is seen to be robust as the overall impact that any one of these uncertainties have on the radiotherapy utilisation rate is relatively minor. However, Monte Carlo simulations can be done in order to assess the impact that these data uncertainties have on the overall radiotherapy utilisation rate in a multivariate fashion. Monte Carlo simulations are based upon the random sampling of variables from discrete and continuous distributions using individual trial data. The main weakness of the Monte Carlo analysis in this study is that the relative importance of all of the data used are weighted by study size and may not necessarily be ranked by study quality. For the various different types of data uncertainties described above, assumptions were made on the distribution of data as described below. For data uncertainties where various different trial data sets were used (Type 1 data uncertainty above), the available trial data were used to calculate betadistributions using FastPro version 1. For most conventional Bayesian calculations of differing datasets, it is usually assumed that these data follow a beta distribution (1). For this Monte Carlo analysis, beta distributions were calculated for each of the uncertain data parameters. These distribution calculations were based upon the sample size and the proportion data quoted in the original paper. For variations in the radiotherapy treatment indication (Type 2 above), the guideline uncertainty could not be modelled for Monte Carlo analysis and therefore the preferred practice as recommended by the guidelines was used in the Monte Carlo analysis. For situations where there was uncertainty in the use of radiotherapy compared to equally efficacious treatment or where the reasonable use of radiotherapy would fluctuate between two extremes based upon subjective criteria (Type 3 above), an estimate based upon current practice was used for the optimal radiotherapy utilisation estimate. To obtain upper and lower bounds we made estimates on the absolute extremes, beyond which it was thought to be unreasonable for the true value to lie, according to expert opinion. For the Monte Carlo simulations these data were modelled assuming a triangular distribution of values which assumes that the estimate based upon current practice is the most likely value and as the values move further away from this value the less frequently they occur in the Monte Carlo simulations. The tightness of the confidence intervals demonstrates that the overall figure is robust. This final estimate is remarkably precise despite uncertainty existing in relation to data. These tight confidence intervals can be explained by the fact that good quality data existed for the initial branches of the tree (eg. Most of the uncertainty existed in the distal or near-terminal branches of the tree and hence affected very small proportions of the cancer population, thus having very little effect on the overall figure. In addition, the effect of these variations was such that some would increase the overall utilisation rate while others would reduce it, so that to a large extent they would cancel each other. Limitations of this study Some limitations of the study have been identified and are discussed below: (a) Quality of data this study has identified the areas where good quality epidemiological data (based on stage, performance status etc. In the meantime, we have overcome the problem by performing modelling and sensitivity analysis to indicate the relatively minor impact that any of these data uncertainties might have on the overall utilisation rate. However, this does not alter the recommendation that better epidemiological data be available in future. To include nonregistered cancers would inflate the numerator of the utilisation rate. Radiotherapy has been identified as an effective treatment for skin cancers and represents a large caseload in some departments. In addition, metastatic involvement of neck lymph nodes by skin cancers in the head and neck is an indication for radiotherapy. The proportion of patients with non-melanomatous skin cancer in the community who, in an ideal, evidence-based world should see a radiation oncologist for treatment is not known. Reports of actual numbers of new cases of skin cancer treated in radiotherapy departments suggest that this indication accounts for 4 to 7 percent of the new cases treated by megavoltage radiation (3-5). In addition, there are a large number of benign tumours that are treated with radiotherapy either definitively or in the adjuvant setting. These benign tumours include pituitary adenomas, pleomorphic adenomas of the parotid gland, meningiomas, craniopharyngiomas and desmoid tumours. For both benign disease and advanced non-melanomatous skin cancers, treatment techniques are often complex and this significantly adds to the radiotherapy resources required to provide quality care for all patients. The only data that could be obtained on the significance of this workload come from productivity statistics from the Alfred Hospital, Melbourne and the Queensland Radium Institute, Brisbane (3-5). Their data showed that non-registered conditions such as benign disease and non-melanomatous skin cancer comprised 12% of their overall workload, underlining the importance of factoring this into the radiotherapy planning process. It is important that this issue is resolved by future research into the optimal rate of utilisation of radiotherapy for skin cancer and benign disease. Non-melanomatous skin cancer (and benign conditions treated by radiotherapy) are not included in the statistics of registered cancers collected by cancer registries; however most radiation oncology departments will count radiotherapeutic treatment of skin cancers in their workload statistics. This is likely to falsely inflate the actual radiotherapy rate for registered cancers, which further confuses the correct rate for planning of resources. We describe how the information (on utilisation of radiotherapy for purposes other than the treatment of registered cancers) might be used in conjunction with the results from this report to assist in determining an appropriate radiotherapy workload in Chapter 20. However these other forms of radiotherapy should be considered when planning radiotherapy resources and could be the subject of a further study. The best way to deal with this problem is with the modelling used in the sensitivity analysis. Although it is only as good as the available evidence, the sensitivity analysis does indicate that most of these uncertainties, even if resolved, would have only a minor effect on the optimal radiotherapy utilisation rate. It was our original intent to include the impact of patient choice on the overall radiotherapy utilisation estimate, particularly as patient choice has a significant role to play. However, the estimate for this study was based upon an ideal situation with no resource constraints. Very few patient-choice studies provided information about whether resource constraints and displacement from home for patients were discussed in the clinical scenario given to the patient. It has been shown that the mastectomy rates for breast cancer among women living in country areas are higher than the mastectomy rates for urban women (6). This difference can be attributed to a relative lack of access to radiotherapy in country areas, leading women to choose mastectomy over radiotherapy and breast-conserving surgery. In addition, some of the studies do not discuss the content of discussions with patients or how information was presented to patients. In situations where descriptions of content and mode of discussion were discussed, the studies were usually hypothetical in that either the subjects were not actually cancer patients or their treatment had already been determined and they were asked to consider a hypothetical situation. It was thought that due to these limitations, patient choice would be flagged as a need for future research but would not be incorporated into the tree. However, data for some indications for radiotherapy were lacking and likely to be exceedingly small. For instance, for patients with metastatic disease, we have included only the more common examples of metastatic disease where radiotherapy might be recommended. However, in many cancers there will be a small proportion of patients who might receive appropriate radiotherapy for metastases at less common sites such as lung, liver, subcutaneous tissue etc. Although only of small overall impact in their own right, the cumulative total of these indications might increase the overall radiotherapy utilisation estimate by 1-2%. Sufficient epidemiological data on the incidence of these metastatic manifestations do not exist to calculate a more accurate figure. Monte Carlo analysis, which allows multivariate assessment of data uncertainty, indicates that the overall radiotherapy utilisation estimate is 52. Monte Carlo analysis demonstrates that, even if there is data uncertainty, our estimate and the overall model is robust. Although the scope of this study is confined to exploring the optimal utilisation of radiotherapy (limited to external beam megavoltage radiotherapy) for registered cancers only, the overall estimate provides a useful tool for assisting in the planning of adequate radiotherapy resources. Potential Uses Potential Uses for the Optimal Radiotherapy Utilisation Estimate and the Treatment Model the model of radiotherapy utilisation developed in this project has many current and future benefits. In addition, this study has highlighted a number of controversies within cancer management. To plan radiotherapy services on a population basis the main reason for calculating an evidence-based assessment of radiotherapy utilisation is because it is invaluable for radiotherapy resource planning. Australian Commonwealth and State agencies have previously assumed that 50 % of all cancer patients will require radiotherapy at some stage (1-5). However, critics have suggested that the figure of 50% is not evidence-based and is perhaps biased. This study recommends an optimal 52% treatment rate figure using an evidence-based approach. An evidence-based estimate will allow more accurate planning of future radiotherapy services. A readily adaptable model of the type described in this paper will allow easy re-calculation should cancer incidence or treatment recommendations change in the future. The model can also be adapted for use in other populations that have differing distributions of cancers and stages at diagnosis such as in countries like India where cervical cancer is much more common than in Australia. However, the evidence-based radiotherapy utilisation estimate needs to be used in context with other indications of radiotherapy not considered by the model when planning radiotherapy. The model uses cancer incidence data on registrable cancers from the cancer registry to estimate demand.

Include a description of the role of the hypothalamic response to cold stress in order to stimulate heat production (shivering allergy medicine 2 years buy 10 mg claritin fast delivery, increased thyroid/catecholamine/adrenal activity) allergy symptoms in kids buy claritin 10mg on line. Define the various types of heat loss: evaporation allergy testing gippsland buy discount claritin 10 mg on-line, radiation allergy forecast honolulu discount claritin 10mg, conduction allergy forecast midland tx discount claritin 10 mg fast delivery, and convection (convective heat loss to cold air and conductive heat loss to water are the most common mechanisms of accidental hypothermia) allergy medicine pseudoephedrine buy claritin 10mg visa. Although not usually related to serious medical problems, in some it may interfere with daily activities, affect quality of life, and in a very few be indicative of serious organic disease. Psychogenic (anxiety, depression) Key Objectives 2 Interpret for patients with tinnitus that any condition of the ear associated with the ear canal (wax, otitis media), cochlear hearing loss, or central nervous system hearing loss can cause tinnitus. Explain that the perception of tinnitus is likely related to the loss of input to neurons in the central auditory pathways resulting in abnormal firing. They require evaluation in the emergency department for triage and prevention of further deterioration prior to transfer or discharge. Early recognition and management of complications along with aggressive treatment of underlying medical conditions are necessary to minimise morbidity and mortality in this patient population. Lacerations and wounds from other causes Key Objectives 2 Evaluate patient according to Advanced Trauma Life Support guidelines so that airway is established and breath sounds are evaluated, the cardiovascular status is stable and peripheral and central lines are secured, neurologic status is fully documented, and with the patient completely exposed (but temperature controlled), all evidence of external injury is evaluated (secondary survey). Briefly outline the process of cell division, regeneration and differentiation as it pertains to wound healing. Explain that shock is associated with systemic reduction in tissue perfusion, thereby resulting in decreased tissue oxygen delivery. Contrast pre-shock (warm or compensated shock) from distributive or low afterload shock. Rupture of a hollow viscus or bleeding from a solid organ may produce few clinical signs. 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). Foreign body Key Objectives 2 Provide initial management and obtain consultation when indicated. Pain usually implies infection whereas difficulty is usually related to distal mechanical obstruction. Urinary frequency (normal or decreased volume) associated with dysuria and/or pyuria a. Irritable bladder (bladder dissynergia) Key Objectives 2 Differentiate between urinary tract infections and conditions outside the urinary tract with similar presentation; determine which infections require treatment, and select the appropriate treatment. Diabetes mellitus is a common disorder with morbidity and mortality that can be reduced by preventive measures. Urinary frequency (normal/decreased volume) associated with dysuria and/or pyuria Key Objectives 2 Evaluate diabetic patients and determine whether diabetic ketoacidosis or hypoglycemia is present; formulate a management plan for diabetic emergencies. Contrast mechanism of hypertension in unilateral obstruction (vasoconstriction secondary to elevated rennin-angiotensin) to bilateral obstruction (volume expansion). Contrast the lack of hydronephrosis with obstruction within the first 1 3 days (the collecting system is relatively uncompliant) to that in more chronic obstruction (collecting system encased by retroperitoneal tumor or fibrosis). Amount or pattern is considered outside normal when it is associated with iron deficiency anemia, it lasts>7days, flow is>80ml/clots, or interval is<24 days. Neoplasms, malignant/benign (endometrial cancer, uterine sarcoma, fibroids, adenomyosis) B. Age related (immature hypothalamic-pituitary-ovarian axis, menopausal ovarian decline) ii. Drugs (hormone replacement, contraception, anticoagulants, chemotherapy, steroids) Key Objectives 2 Determine whether the patient is hemodynamically stable prior to any other task. In a patient with vaginal bleeding, where sexual abuse is suspected, legal definitions may be needed. Victims should be asked to sign consent forms prior to collection of any samples for evidence. Such samples, if consent is given, should be collected at the time of the initial evaluation and stored securely even if the patient eventually decides against reporting the abuse. Contrast ovarian function during menstruation to peri-menopause/menopause (intermittent anovulation as ovarian function declines to chronic anovulatory cycles and progesterone deficiency with unopposed estrogen exposure). Desquamative inflammatory vaginitis/Focal vulvitis Key Objectives 2 Determine the appearance of the discharge, but state that appearance may be misleading, and up to 20% of patients may have two coexistent infections. Domestic violence is one of them, since it has both direct and indirect effects on the health of populations. Intentional controlling or violent behavior (physical, sexual, or emotional abuse, economic control, or social isolation of the victim) by a person who is/was in an intimate relationship with the victim is domestic violence. The victim lives in a state of constant fear, terrified about when the next episode of abuse will occur. Despite this, abuse frequently remains hidden and undiagnosed because patients often conceal that they are in abusive relationships.

Kendall A complete list of the titles in this series appears at the end of this volume. Kendall the Wiley Series in Probability and Statistics is well established and authoritative. It covers many topics of current research interest in both pure and applied statistics and probability theory. Written by leading statisticians and institutions, the titles span both state-of-the-art developments in the field and classical methods. Reflecting the wide range of current research in statistics, the series encompasses applied, methodological and theoretical statistics, ranging from applications and new techniques made possible by advances in computerized practice to rigorous treatment of theoretical approaches. This series provides essential and invaluable reading for all statisticians, whether in academia, industry, government, or research. 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. 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.
