Cardiac ultrasound has diagnostic applications that are particularly suited to the developing world because of its non-invasive nature buy trandate 100mg hypertension definition. Internationally order 100mg trandate free shipping blood pressure goals chart, it is believed that radiotherapy will continue to be key for the treatment of cancer in the coming decades for its curative function, which is particularly important for tumours of the head and neck, cervix–uterus, breast and prostate, and for its palliative function and effectiveness. Early detection methods for breast cancer, such as clinical exploration, ultrasound or mammography, improve the outcome of treatment. In addition, ultrasound is an essential component of the diagnosis and staging of breast cancer. Injury is the ninth most common cause of premature death worldwide and the third most common cause of years lived with disability. Most traffic related deaths take place in low and middle income countries among young men 15–44 years old. Road traffic deaths are likely to increase by more than 80% in developing countries by 2030 [7]. Low income countries are also particularly vulnerable to intentional or non-intentional injuries, including natural disasters and war. Much of the mortality due to injuries and trauma could be avoided by timely stabilization and medical care, and timely use of emergency equipment, including basic diagnostic tests. Easy to use ultrasound devices for diagnosis of internal, especially intra-abdominal, bleeding would also be a useful development. Emergency care, including imaging techniques to diagnose bone trauma in health care facilities, is necessary for immediately addressing urgent health issues and to prevent long term disability. Standard radiology remains the major diagnostic tool for trauma and some types of injury. However, health systems in many developing countries are highly segmented and the provision of health services is very fragmented. Experience to date demonstrates that excessive fragmentation leads to difficulties in access to services, delivery of services of poor technical quality, irrational and inefficient use of available resources, unnecessary increases in production costs and low user satisfaction with services received [8]. The specialized training needed to diagnose such diseases is a challenge for low and middle income countries. On the other hand, the lack of comprehensive cancer control programmes, including access to treatment services with radiotherapy, represents the major obstacle for reducing cancer mortality in developing countries. Technology and infrastructure Radiation medicine technology is associated with high costs from the acquisition to the functional phase, including maintenance needs and environmental conditions. The costs of these services, considering both the initial investment and operating costs, make careful planning and management of their development necessary, but the latter are not always adequate. Frequently, the costs of procuring and maintaining equipment are much higher than in industrialized countries. All these aspects become more critical with the incorporation of more complex and costly technologies. Almost two thirds of all low income countries do not have a national health technology policy in the national health programmes to guide the planning, assessment, acquisition and management of medical equipment. As a result, inappropriate medical devices that do not meet the priority needs of the population, are not suited to the existing infrastructure and are too costly to maintain are incorporated, draining funds needed for essential health services [9]. Much of the most complex equipment imported from industrialized regions does not work when it reaches low income countries. Maintenance of diagnostic equipment plays a very significant role in the longevity and effectiveness of diagnostic machines, as well as in safety and quality. Better technology policy in countries will lead to an increase in the quality, effectiveness and coverage of health care with regard to medical devices. In some countries, the low demand for medical technology often derives from deep rooted culture and social norms. At the beginning of the symptoms, people tend to solve their problems with traditional medical services or even magic–religious approaches. Many prefer traditional over modern therapies, and it is very common to use a of combination of both. Often, when appropriate results are not produced, the patient then seeks modern medicine. Although the introduction of new technologies and techniques is necessary in some countries, awareness of the traditions and beliefs may be crucial to the success of any project.

Caucasians eating an essentially carbohydrate-free diet generic trandate 100mg visa blood pressure medication ingredients, resembling that of Greenland natives trandate 100 mg free shipping arrhythmia icd 9 codes, for a year tolerated the diet quite well (Du Bois, 1928). However, a detailed modern comparison with populations ingesting the majority of food energy as carbohydrate has never been done. It has been shown that rats and chickens grow and mature success- fully on a carbohydrate-free diet (Brito et al. It has also been shown that rats grow and thrive on a 70 percent protein, carbohydrate-free diet (Gannon et al. Azar and Bloom (1963) also reported that nitrogen balance in adults ingesting a carbohydrate-free diet required the ingestion of 100 to 150 g of protein daily. The ability of humans to starve for weeks after endogenous glycogen supplies are essentially exhausted is also indicative of the ability of humans to survive without an exogenous supply of glucose or monosaccharides convertible to glucose in the liver (fructose and galactose). However, adaptation to a fat and protein fuel requires considerable metabolic adjustments. The only cells that have an absolute requirement for glucose as an oxidizable fuel are those in the central nervous system (i. The central nervous system can adapt to a dietary fat-derived fuel, at least in part (Cahill, 1970; Sokoloff, 1973). Also, the glycolyzing cells can obtain their complete energy needs from the indirect oxidation of fatty acids through the lactate and alanine-glucose cycles. In the absence of dietary carbohydrate, de novo synthesis of glucose requires amino acids derived from the hydrolysis of endogenous or dietary protein or glycerol derived from fat. Therefore, the marginal amount of carbohydrate required in the diet in an energy-balanced state is condi- tional and dependent upon the remaining composition of the diet. Never- theless, there may be subtle and unrecognized, untoward effects of a very low carbohydrate diet that may only be apparent when populations not genetically or traditionally adapted to this diet adopt it. Of particular concern in a Western, urbanized society is the long-term consequences of a diet sufficiently low in carbohydrate such that it creates a chronically increased production of β-hydroxybutyric and acetoacetic acids (i. The concern is that such a diet, deficient in water- soluble vitamins and some minerals, may result in bone mineral loss, may cause hypercholesterolemia, may increase the risk of urolithiasis (Vining, 1999), and may affect the development and function of the centra1 ner- vous system. It also may adversely affect an individual’s general sense of well being (Bloom and Azar, 1963), although in men starved for an extended period of time, encephalographic tracings remained unchanged and psychometric testing showed no deficits (Owen et al. The latter is required for hypoglycemic emergencies and for maximal short-term power production by muscles (Hultman et al. Glucose production has been deter- mined in a number of laboratories using isotopically labeled glucose (Amiel et al. In the postabsorptive state, approximately 50 percent of glucose production comes from glycogenolysis in liver and 50 percent from gluconeogenesis in the liver (Chandramouli et al. The minimal amount of carbohydrate required, either from endogenous or exogenous sources, is determined by the brain’s requirement for glucose. The brain is the only true carbohydrate-dependent organ in that it oxidizes glucose completely to carbon dioxide and water. The endogenous glucose production rate in a postabsorptive state correlates very well with the esti- mated size of the brain from birth to adult life. The requirement for glucose has been reported to be approximately 110 to 140 g/d in adults (Cahill et al. Nevertheless, even the brain can adapt to a carbohydrate-free, energy-sufficient diet, or to starvation, by utilizing ketoacids for part of its fuel requirements. When glucose produc- tion or availability decreases below that required for the complete energy requirements for the brain, there is a rise in ketoacid production in the liver in order to provide the brain with an alternative fuel. It is associated with approximately a 20 to 50 percent decrease in circulating glucose and insulin concentration (Carlson et al. These are signals for adipose cells to increase lipolysis and release nonesterified fatty acids and glycerol into the circulation. The signal also is reinforced by an increase in circulat- ing epinephrine, norepinephrine, glucagon, and growth hormone con- centration (Carlson et al.

Human When one enters the medical college the first thing that body is not only non-linear,it follows the holistic rules of happens is that the person is made to forget his/her the universe. All these make the present the present educational system; even as early as entry to medical science a square plug in a round hole. In the practice of bedside medicine, progress and if we want to progress in medical science however, common sense is not just common but it is we have to think deeply of changing our mind set and commoner than what one thinks it is. The statistical science follow the new science of chaos-of non-linearity and of medicine can, at best, manage to size up cohorts of holism. It is basically status quoists wanting the comfort of the existing the past experience of the doctor with his clinical acumen order. We are usually afraid of change and what it might that helps him at that point in time. But life itself is ceaseless change till decision one way or the other based on his own death. Unfortunately, that is what medicine, sold as the gold standard in medical research, is presumed in the science of medicine. The British claim The art of medicine is the one that makes the patient’s that it was Archie Cochrane that introduced the term and day. No amount of science and technology will ever be they claim that the first such study was undertaken by able to replace that humane human being, the doctor their Medical Research Council in 1940 of the role of that alone could put to rest the universal anxiety that is streptomycin in tuberculosis and on the role of the part of all illnesses since every disease presents through whooping cough vaccine.

Large sections of the The linear thinking in medical sciences with the population live without the benefit of modern medicine.

We only have to change our attitude to authentic methods in other systems as well that might those methods and we could always use our modern help us unravel the mystery. Our ostrich like attitude denies scientific methods to evaluate their efficacy and then the ardent student in the medical school even a remote accept or reject rather than prejudging their capacity.

The diagnoses of patients that have been most recently cared for are the ones that are brought to the forefront of one’s consciousness purchase 100mg trandate with visa arteria jugularis. If a physician recently took care of a patient with a sore throat who had gon- orrhea purchase trandate 100 mg line blood pressure zetia, he or she will be more likely to look for that as the cause of sore throat in the next patient even though this is a very rare cause of sore throat. The availability heuristic is much more problematic and likely to occur if a recently missed diagnosis was of a rare and serious disease. This heuristic refers to the reality that special characteristics of a patient are used to estimate the probability of a given diagnosis. A differential diagnosis is initially formed and additional infor- mation is used to increase or decrease the probability of disease. This tech- nique is the way we think about most diagnoses, and is also called the com- peting hypotheses heuristic. For example, if a patient presents with a sore throat, the physician should think of common causes of sore throat and come up with diagnoses of either a viral pharyngitis or strep throat. After getting more history and doing a physical examina- tion the physician decides that the characteristics of the sore throat are more like a viral pharyngitis than strep throat. This is the adjustment, and as a result, the other diagnoses on the differential diagnosis list are considered extremely unlikely. The adjustment is based on diagnostic information from the history and physical examination and from diagnostic tests. Throughout the patient encounter, new information An overview of decision making in medicine 231 Fig. The problem of premature closure of the differential diagnosis One of the most common problems novices have with diagnosis is that they are unable to recognize atypical patterns. This common error in diagnostic think- ing occurs when the novice jumps to the conclusion that a pattern exists when in reality, it does not. There is a tendency to attribute illness to a common and often less serious problem rather than search for a less likely, but potentially more seri- ous illness. It rep- resents removal from consideration of many diseases from the differential diag- nosis list because the clinician jumped to a too early conclusion on the nature of the patient’s illness. Even experienced clin- icians can make this mistake, thinking that a patient has a common illness when, in fact, it is a more serious but less common one. No one expects the clinician to always immediately come up with the correct diagnosis of a rare presentation or a rare disease. However, the key to good diagnosis is recogniz- ing when a patient’s presentation or response to therapy is not following the pattern that was expected, and revisiting the differential diagnosis when this occurs. Premature closure of the differential diagnosis can be avoided by following two simple rules. The first is to always include a healthy list of possibilities in the dif- ferential diagnosis for any patient. When one finds oneself commonly diagnosing a patient within the first few minutes of initiating the history, step back and look for other clues that could dismiss one diagnosis and add other diagnoses to the list. Then ask one- self whether those other diseases can be excluded simply through the history 232 Essential Evidence-Based Medicine and physical examination. Since most common diseases do occur commonly, the disease that was first thought of will often turn out to be correct. However, it is more likely to miss important clues of the presence of another less common disease if a physician focuses only on that first diagnosis. The second step is to avoid modifying the final list until all the relevant infor- mation has been collected. After completing the history, make a detailed and objective list of all the diseases for consideration and determine their relative probabilities. The formal application of such a list will be invaluable for the novice student and resident, and will be done in a less and less formal way by the expert.

During the clinical encounter, the physician has the opportunity to gather the most accurate information about the nature of the illness and the meaning of that illness to the patient. If there are errors made in processing this information, the resulting decisions may not be in the patient’s best interests. This can lead to overuse, underuse, or misuse of therapies and increased error in medical practice.
