Bear in mind that a patient is more likely to present with a rare or unusual presentation of a common disease cheap carafate 1000 mg without prescription, than a common presentation of a rare disease generic carafate 1000 mg visa. As stated earlier cheap carafate 1000 mg fast delivery, the first step in generating a differential diagnosis is to sys- tematically make a list of all the possible causes of a patient’s symptoms. This skill is learned through the intensive study of diseases and reinforced by clinical experience and practice. When medical students first start doing this, it is useful to make the list as exhaustive as possible to avoid missing any diseases. Think of all possible diseases by category that might cause the signs or symptoms. There are several helpful mnemonics that can help get a differential diagnosis started. The values of pretest probability are relative and can be assigned according to the scale shown in Table 20. Physicians are more likely to agree with each other on prioritizing diagnoses if using a relative scale like this, rather than trying to assign a numerical probability to each disease on the list. If the disease is immediately life- or limb-threatening, it needs to be ruled out, regardless of the probability assigned. If the likelihood of a disease is very very low, the diagnostician should look for evidence that the disease might be present, such as an abberrent ele- ment of the history, physical examination or diagnostic tests to suggest that the An overview of decision making in medicine 225 Table 20.

But, must Rare disease (rare consider if other diseases later are presentation) found not to be present. This is a unique presentation of this disease, and therefore the patient can only have this disease. We will use this schema for selecting pretest probabilities for the rest of the book. For example, if a 21-year-old man came in to the Emergency Department complaining of chest pain, a physician would first perform a complete his- tory and physical examination. Following this, one might suspect that anxiety 226 Essential Evidence-Based Medicine or a pectoralis muscle strain are the cause of his pain. One should also consider slightly less likely and more serious causes which are easily treatable, such as pericarditis, spon- taneous pneumothorax, pneumonia, or esophageal spasm secondary to acid reflux. Next, there are hypotheses that are much less likely, such as myocardial infarction, dissecting thoracic aortic aneurysm, and pulmonary embolism. Finally, one must consider some disorders, such as lung cancer, that are so rare and not immediately life- or limb-threatening that they are ruled out because of the patient’s age. If a 39-year-old man presented with the same complaint of chest pain, but not the typical sqeezing, pressure-like pain of angina pectoris, one could look up the pretest probability of coronary artery disease in population studies. This can be found in an article by Patterson, which states that the probability that this patient has angina pectoris is about 20%. These data would change one’s list and put myocardial infarction higher up on the differential. Since this is a potentially dangerous disease, additional testing is required to rule it out. Making the differential diagnosis means considering diseases from three per- spectives: probability of the disease, severity of the disease, and ease of treatment of the disease. The differential diagnosis is a complex interplay between these factors and the patient’s signs and symptoms. The pysician suspects that this child might have strep throat, which is a common illness in children and thus assigns it a high pretest probability of disease. The dif- ferential diagnosis also includes another common disease, viral pharyngitis. Also included are uncommon diseases like epiglottitis, which is severe and life- threatening, and mononucleosis. For this patient’s workup, the more serious and uncommon diseases must be actively ruled out. In this case, that can almost certainly be done with an accurate history disclosing lack of sexual abuse and oral–genital contact to rule out gonorrhea.

Lack of physical signs of epiglottitis such as difficulty swallowing, drooling, and stridor would rule out epiglottitis, and lack of symptoms of fatigue and physical signs like cervical adenopathy would rule out mononucleosis. If there are no characteristic signs and symptoms of epiglottitis, mononucle- osis, gonorrhea, or diphtheria, then the differential diagnosis narrows down to strep throat and viral pharyngitis. The physician can then apply a published deci- sion rule to differentiate strep throat from viral pharyngitis.

The availability of over 1 order carafate 1000 mg,500 genetic tests and several targeted therapies and the use of pharmacogenomic data for drug and dosage selec-1 2 tion suggest that genomics is already integrated into healthcare and that it will be a game changer order carafate 1000mg line. On the other hand buy cheap carafate 1000 mg on line, there is scepticism regarding the current and future impact of genomics in healthcare because of the lack of everyday use of such technolo- gies in clinical practice, the questionable clinical utility and validity of some genetic tests and the availability of only a handful of targeted therapies amidst others that have failed clinical trials. Regardless of which position one chooses to take, recent accomplishments in genomics demonstrate that healthcare stakeholders have a remarkable opportunity – an oppor- 1 A type of treatment that uses drugs or other substances, such as monoclonal antibodies, to identify and attack specific cancer cells. Targeted therapy may have fewer side effects than other types of cancer treat- ments (National Cancer Institute N. Data from a number of recent publications and websites affirm that the current use of genomics in everyday clinical practice represents only the tip of the iceberg. In the case of chronic diseases in particular, such data will lead to significant pre-emptive measures to prevent the onset of disease years in advance of symptoms appearing. This paper examines these enablers and outlines opportunities for health service organizations and health professionals to plan for the integration of genomics in healthcare. The genetic alphabet contains four nucleotides bases – adenine, guanine, cytosine and thymine – which chemically combine in pairs: adenine with cytosine and guanine with thymine. It is estimated that there are three billion base pairs in the human genome and approximately 20,000–25,000 protein-coding genes. Clearly, the billion-plus data elements needed to define even one person’s genetic signature are several orders of magnitude more complex than the few hundred to few thousand data points in a traditional medical record. Rather than dealing with diseases after they have manifested themselves, genomics allows clinicians to look into a person’s future and determine what diseases that person is susceptible to and which drugs and interventions hold the highest likelihood for success. It changes healthcare from retrospective, interventional care to prospective, preventative care that is highly personalized and pre-emptive. The true value of genomic medicine rests in understanding and incorporating genomic information, both from clinical and research outcomes, into a person’s health record. Genomics will become an integral part of a person’s medical record for the following reasons: • The cost of sequencing an individual complete genome will decrease from hundreds of thousands of dollars to under $1,000. Genomic medicine will also have a significant impact on healthcare delivery due to its intensely personal, predictive, ethical, legal and social dimensions and impacts. She would then face emotional upheaval on learning her risk for breast and ovarian cancer and a very personal choice regarding what to do with this information (e. Genomic testing therefore creates a new demand for people who can interpret and accurately and compassionately deliver such information. Genomics is already impacting healthcare, although mainly in specialized settings. Figure 1 depicts early successes in specific types of cancer, where genomics has already enabled pre-symptomatic diagnosis, personalized therapy and personalized drug dosages. Genomics enabled approach to specific cancers Pre-symptomatic or symptomatic Targeted therapy Pharmacogenomic gene test, risk, prediction testing for dosage Pre-symptomatic diagnosis Personalized therapy Personalized drug dosage e. These data provide a basis for diagnosis and, if possible, a determination of personalized treatment(s). However, the presence of mutations in these genes increases the lifetime “likelihood” of developing breast cancer and other cancers, such as ovarian cancer. Predisposition testing can also test for rarer gene disorders that manifest in adulthood (e. Pharmacogenomic testing enables an understanding of how an individual’s genetic variation for specific drug-metabolizing enzymes may affect the body’s response to the drug being administered (Epstein 2004; Johnson 2003). Using such profiles to adjust warfarin dosage can prevent complications of warfarin treatment. Most drugs produce a spectrum of responses in various people: from no effect in some, to a moderate effect in most, to an absolute cure in a few. Targeted therapy aims to identify those persons for whom a given drug is highly efficacious, and avoid giving the drug to those in whom it will have little or no effect. This not only provides a path to novel therapies, but also rehabilitates older drugs that have cured some people, but on average have had little effect or been overly toxic. The genomic approach toward drug-target isolation offers significant advantages over the tried and tested approaches that pharmaceutical companies have used. Such therapies are precise and hence possess high efficacy, but often only in a subset of individuals with a specific condition. For example, screening for and treating phenylketonuria provides net direct cost savings to society. In the case of imatinib, a first-line therapy for chronic myeloid leukemia, a six-year increased survival rate over interferon-alpha therapy has been noted, with a $43,100 per life-year saving (Reed et al. Prenatal genetic testing, genetic predisposition testing and pharmacogenomic testing are three categories of tests which are regularly being offered to healthcare consumers today. However, data from research studies detailing clinical outcomes based on pharmacogenomic testing and the appropriate dosage of specific drugs remain sparse.

That is generic carafate 1000 mg with visa, useful and acceptable imaging guidelines must form a computer based decision support system discount carafate 1000mg with mastercard. Example of an appropriateness criteria table generic carafate 1000 mg overnight delivery, for one of six variants of the topic ‘low back pain’, with ratings for modalities and relative radiation level. The development of such a decision support system faces many challenges, including those of software development, hardware availability, system compatibility and interconnectivity, and availability of content with satisfactory breadth, depth and scientific validity. There are two major advantages to this: first, there is extensive prior experience with a clinical imaging decision support system which will help to inform the current effort. Usual practice varies widely from region to region, and nation to nation, as does the availability of equipment and the prevalence of disease, all of which influence the recommendations from a decision support system. While there are often clear justifications for performing diagnostic imaging examinations, there are many situations in which justification is more arguable. Determining what is justified is an extremely complicated aspect of medical practice as it potentially involves multiple health care providers, with varying levels of experience, anecdotal based decision making and a broad variety of other forces. It is beyond the intent of this paper to fully dissect this aspect of justification in medical imaging. However, there are tools that are becoming available for improving evidence based medicine, including decision rules, practice guidelines and appropriateness criteria, and point-of-care decision support. Many of these advancements are becoming embedded in electronic health care systems. The following material will present background information, define some of the terminology involved in ‘algorithms’ for improving justification, address the current status, provide some of the challenges in implementing models for improved justification of medical imaging, and present some of the current needs. This increased use of medical imaging has some associated potential health risks, but costs also include financial implications for health care delivery as well as utilization of often limited resources, such as equipment and medical personnel. Similar comments of overutilization of 20–30% of imaging examinations are encountered elsewhere in the literature [3]. However, I would argue that overutilization is a very complicated topic and does not lend itself easily to the simplified percentage derivations of utilization. For example, utilization can be driven by evidence, or other accepted medical benefit, industry marketing, use by non-imaging experts (i. Once again, determining whether this is due to self-referral or other factors is extremely difficult. Other influences include reimbursement through government or private payers, legal forces, the media, and the expectation of patients and the public. All of the above can combine to give quite different perspectives on and decisions for what is appropriate and inappropriate in medical imaging for similar clinical circumstances for different patients. In addition, levels of training, overall expertise and experiential/ anecdotal factors can drive imaging use. This illustrates the fact that practice environments and landscapes might also drive utilization. Terms applied in discussions of utilization/justification include ‘excessive’, ‘ineffective’, ‘unjustified’, ‘inappropriate’ and ‘overutilized’ with respect to medical imaging. Often, these comments come from radiology sources and, whether directly or indirectly, imply that our clinical colleagues are ‘ordering too many studies’. I find this very difficult to support; it conveys an antagonistic and confrontational (at best, judgemental) environment which serves little purpose in arriving at the requisite consensus strategies and solutions. In the setting of justification of medical imaging, I believe using the word ‘inappropriate’ is, with some irony, ‘inappropriate’. Some of the steps to reducing the questionable utilization in imaging were nicely outlined by Hendee et al. Note that the top of the list contained many items relevant to this current paper. Justification will be dealt with in much greater detail in other aspects of this conference. I see this as breaking down more simply to an equation: If A, then the probability of B is… Reilly and Evans [10] recently provided some of the strategies to overcome barriers to effective use of decision rules. They embody the best, current evidence for selecting appropriate diagnostic imaging and interventional procedures for numerous clinical conditions” [11]. If suspect A, then the pathway(s) to B to follow is/are… Finally, decision support is information available at the point-of-care. Decision support, and the benefits and difficulties were recently outlined by Boland et al. In this publication, comments included that decision support must evolve through computer order entry systems, should alter behaviour, and improve utilization through evidence based medicine. The publication concluded noting that decision support is an added value for radiology.

This fusion of Soranus’s nosographies and therapies with Galenic theory resulted in the creation of a Galenic gynecology 1000 mg carafate visa, which bore the distinctive stamp of its Arab and Muslim creators cheap 1000mg carafate with visa, not only for the increased philosophical rigidity of the humoral system (which Galen had never been so formal about) buy generic carafate 1000 mg on line, but also for the new, unique Arabic contribu- tions to therapy and especially to materia medica (pharmaceutical ingredients). Thus, for example, when the North African writer Ibn al-Jazzār described the various possible causes of menstrual retention, he distinguished between the faculty, the organs, and the substance (of the menses themselves) as the caus- ative agents, dialectically breaking down each of these three categories into their various subcategories. Whereas in modernWestern medical thought menstruation is seen as a mere by-product of the female reproductive cycle, a monthly shedding of the lining of the uterus when no fertilized ovum is implanted in the uterine wall, in Hippocratic and Galenic gynecology menstruation was a necessary purgation, needed to keep the whole female organism healthy. The Hippocratic writers had been incon- sistent on whether women were hotter or colder than men by nature. In Galenic gynecology, in contrast (which in this respect built on the natural philosophical principles of Aristotle), women were without question constitu-  Introduction tionallycolder than men. Men, moreover, were also able to exude those residues of digestion that did remain through sweat or the growth of facial and other bodily hair. Because (it was assumed) women exerted them- selves less in physical labor even while they produced, because of their insuf- ficient heat, a greater proportion of waste matter, they had need of an addi- tional method of purgation. For if women did not rid their bodies of these excess materials, they would continue to accumulate and sooner or later lead to a humoral imbalance—in other words, to disease. When, too, she did not menstruate because of pregnancyor lactation, she was still healthy, for the excess matter—now no longer deemed ‘‘waste’’—either went to nourish the child in utero or was converted into milk. When, however, in a woman who was neither pregnant nor nursing menstrua- tion was abnormal, when it was excessive or, on the other hand, too scanty, or worse, when it stopped altogether, disease was the inevitable result. Nature, in her wisdom, might open up a secondary egress for this waste material; hence Conditions of Women’s suggestion that blood emitted via hemorrhoids, nosebleeds, or sputum could be seen as a menstrual substitute (¶). In mod- ern western medicine, absence of menstruation in a woman of child-bearing age might be attributable to a variety of causes (e. It might not even be deemed to merit therapeutic intervention, unless the woman desired to get pregnant. In Hippocratic and Galenic thought, ab- sence of menstruation—or rather, retention of the menses, for the waste ma- terial was almost always thought to be collecting whether it issued from the body or not—was cause for grave concern, for it meant that one of the major purgative systems of the female body was inoperative. It is for this reason that the largest percentage of prescriptions for women’s diseases in most early medi- eval medical texts (which reflected the Hippocratic tradition only) were aids for provoking the menses. Between the ages of fourteen (‘‘or a little earlier or a little later, depending on how much heat abounds in her’’)84 and thirty-five to sixty Introduction  (upped to sixty-five in the standardized ensemble), a woman should be men- struating regularly if she is to remain healthy. In overall length, the four sections on menstruation (¶¶– on the general physiology and pathology of menstruation, ¶¶– on menstrual retention, ¶¶– on paucity of the menses, and ¶¶– on excess men- struation) constitute more than one-third of the text of the original Conditions of Women. Throughout these long sections on menstruation, the author is adhering closely to his sources: the Viaticum for overall theory and basic therapeutics and the Book on Womanly Matters for supplemental recipes. In ¶, the author tells us that the menses are commonly called ‘‘the flowers’’ because just as trees without their flowers will not bear fruit, so, too, women without their ‘‘flowers’’ will be deprived of off- spring. This reference to ‘‘women’s flowers’’ has no precedent in the Viaticum (the source for the rest of this general discussion on the nature of the menses) nor in any earlier Latin gynecological texts, which refer to the menses solely as menstrua (literally, ‘‘the monthlies’’). Theterm‘‘flower’’(flos) had been used systematically throughout the Trea- tise on the Diseases of Women (the ‘‘rough draft’’ of Conditions of Women, which had employed frequent colloquialisms), and at least fourteen of the twenty- two different vernacular translations of the Trotula (including Dutch, English, French, German, Hebrew, and Italian) employ the equivalent of ‘‘flowers’’ when translating the Latin menses. But just as a tree which lacks viridity is said to be unfruitful, so, too, the woman who does not have the viridity of her flowering at the proper age is called infertile. Menstrual blood is like the flower: it must emerge before the fruit—the baby—can be born. In the Hippocratic writings themselves, although there is discussion of suffocation caused by the womb, the actual term ‘‘uterine suffocation’’ (in Greek, hysterike pnix) is never used. It was only out of loose elements of Hip- pocratic disease concepts (which were always very vaguely defined and iden- tified) that the etiological entity of uterine suffocation was created, probably sometime before the second century . Such movement was thought to be caused by retention of the menses, excessive fatigue, lack of food, lack of (hetero)sexual activity, and dryness or lightness of the womb (particu- larly in older women). When these conditions obtain, the womb ‘‘hits the liver and they go together and strike against the abdomen—for the womb rushes and goes upward towards the moisture. When the womb hits the liver, it produces sudden suffocation as it occupies the breathing passage around the belly. For example, when the womb strikes the liver or abdomen, ‘‘the woman turns up the whites of her eyes and becomes chilled; some women are livid. If the womb lingers near the liver and the abdomen, the woman dies of the suffocation. Multiple means of treat- ment were employed, including the recommendation that, when the womb moves to the hypochondria (the upper abdomen or perhaps the diaphragm), young widows or virgins be urged to marry (and preferably become preg- nant). This was premised, apparently,on the belief that thewombwas capable of sensing odors. Fetid odors (such as pitch, burnt hair, or castoreum) were applied to the nos- trils to repel the womb from the higher places to which it had strayed, while sweet-smelling substances were applied to the genitalia to coax the uterus back into its proper position. Not all the symptoms were listed every time uterine movement was men- tioned by the Hippocratic writers, nor did all cases of pnix involve uterine movement.

More recently effective 1000 mg carafate, in a study of 10 purchase 1000 mg carafate with visa,802 health- conscious men and women in the United Kingdom discount 1000 mg carafate with visa, a univariate relation- ship of cholesterol intake to ischemic heart disease mortality was observed (Mann et al. This finding was corroborated in a European study, but after multivariate analysis adjust- ing for fiber intake, the association was no longer significant (Toeller et al. Measures of atherosclerosis using imaging techniques have also been assessed in relation to diet. Angiographically assessed coronary artery disease progression over 39 months in 50 men was weakly related to cholesterol intake in univariate, but not multivariate, analysis (Watts et al. In 13,148 male and female participants in the Atherosclerosis Risk in Commu- nities Study, carotid artery wall thickness, an index of early atherosclerosis, was significantly related to dietary cholesterol intake by univariate analyses; multivariate analysis was not performed (Tell et al. Another uncertainty relates to interpreting the effects of dietary cholesterol on blood cholesterol concentrations. Finally, the considerable interindividual variation in lipid response to dietary cholesterol may result in differing outcomes in differ- ent populations or population subgroups. Cancer As shown in Tables 9-5 through 9-8, no consistent significant associa- tions have been established between dietary cholesterol intake and cancer, including lung, breast, colon, and prostate. Several case-control studies have suggested that a high consumption of cholesterol may be associated with an increased risk of lung cancer (Alavanja et al. As reviewed above, on average, an increase of 100 mg/d of dietary cholesterol is predicted to result in a 0. This effect of added cholesterol is highly variable among individuals and is considerably attenuated at higher baseline cholesterol intakes. Epidemiological studies have limited power to detect effects of such magnitude and thus do not provide a meaningful basis for establishing adverse effects of dietary cholesterol. However, no studies have examined the effects of very small increments of dietary cholesterol in numbers of subjects suffi- ciently large enough to permit statistical treatment of the data. Because cholesterol is unavoidable in ordinary, nonvegan diets, eliminating choles- terol in the diet would require significant changes in patterns of dietary intake.
