For some medical issues 100mg kamagra overnight delivery, gender kamagra 100 mg amex, ethnicity generic 50mg kamagra, or cultural background has a huge influence while for other medical issues the influence is very little. To determine which areas fall into each category, more studies of gender and other differences for medical interventions are required. Coherence of the evidence over time In order to have strong evidence, there should be consistency of the evidence over varying types of studies. The results of a cohort study should be similar to those of case–control or cross-sectional studies done on the same cause-and- effect relationship. Studies that show consistency with previously known epi- demiological data are said to evidence epidemiological consistency. Also, results should agree with previously discovered relationships between the presumed cause and effect in studies done on other populations around the world. An 196 Essential Evidence-Based Medicine association of high cholesterol with increased deaths due to myocardial infarc- tion was noted in several epidemiological studies in Scandinavian countries. Analogy Reasoning by analogy is one of the weakest criteria allowing generalization. Knowing that a certain vitamin deficiency predisposes women to deliver babies with certain birth defects will marginally strengthen the evidence that another vitamin or nutritional factor has a similar effect. When using analogy, the pro- posed cause-and-effect relationship is supported by findings from studies using the same methods but different variables. From this, one could infer that a potent anticoagulant like warfarin ought to have the same effect. However, warfarin may increase mortality because of the side effect of causing increased bleeding. Again, although it is suggested by an initial study, the proposed new intervention may not prove beneficial when studied alone. Common sense Finally, in order to consider applying a study result to a patient, the association should make sense and competing explanations associating risk and outcome should be ruled out. For instance, very sick patients are likely to have a poor out- come even if given a very good drug, thus making the drug look less efficacious than it truly is. Conversely, if most patients with a disease do well without any therapy, it may be very difficult to prove that one drug is better than another for that disease. When dealing with this effect, an inordinately large number of patients would be necessary to prove a beneficial effect of a medication. It may lead to the overselling of potent drugs, and may result in clinical researchers neglecting more common, cheaper, and better forms of therapy. Similarly, patients thinking that a new wonder drug will cure them may delay seeking care at a time when a potentially serious problem is easily treated and complications averted. Finally, it is up to the individual physician to determine how a particular piece of evidence should be used in a particular patient. As stated earlier, this is the art Applicability and strength of evidence 197 Fig. We must learn to use the best evi- dence in the most appropriate situations and communicate this effectively to our patients. There is a real need for more high-quality evidence for the practice of medicine, however, we must treat our patients now with the highest-quality evidence available. Pathman’s Pipeline The Pathman ‘leaky’ pipeline is a model of knowledge transfer, taking the best evidence from the research arena into everyday practice. This model considers the ways that evidence will be lost in the process of diffusion into the everyday practice of medicine. Pathman, a family physician in the 1970s, to model the reasons why physicians did not vaccinate children with routine vaccinations. It has been expanded to model the reasons that physicians don’t use the best evidence (Fig. They must then accept the evidence as being legitimate 198 Essential Evidence-Based Medicine and useful. This follows a bell-shaped curve with the innovators followed by the early adopters, early majority, late majority, and finally the laggards. Providers must believe that the evidence is applicable to their patients, specifically the one in their clinic at that time. However, it is still up to the patient to agree to accept the evidence and finally be com- pliant and adhere to the evidence. The next chapter will discuss the process of communication of the best evidence to patients.

Training for health care professionals in radiation protection should be related to their specific jobs and roles order kamagra 50mg line. The physicians and other health professionals involved in procedures that irradiate patients should always be trained in the principles of radiation protection generic kamagra 50 mg visa, including the basic principles of physics and biology order 50 mg kamagra visa. The final responsibility for radiation exposure lies with the physician providing the justification for the exposure being carried out, who should, therefore, be aware of the risks and benefits of the procedures involved. Education and training appropriate to the role of each category of physician should be given at medical schools during residency and in focused specific courses. There should be an evaluation of the training and appropriate recognition that the individual has successfully completed the training. In addition, there should be corresponding radiation protection training requirements for other clinical personnel that participate in the conduct of procedures utilizing ionizing radiation, or in the care of patients undergoing diagnosis or treatment with ionizing radiation. Scientific and professional societies should contribute to the development of the syllabuses, and to the promotion and support of the education and training. Scientific congresses should include refresher courses on radiation protection, attendance at which could be a requirement for continuing professional development for professionals using ionizing radiation. Professionals involved more directly in the use of ionizing radiation should receive education and training in radiation protection at the start of their career, and the education process should continue throughout their professional life as the collective knowledge of the subject develops. It should include specific training on related radiation protection aspects as new equipment or techniques are introduced into a centre. A major test Adequate education and training of medical staff and practitioners is considered paramount and the major route to ensuring appropriate radiological protection in medicine. In pursuit of medical, dental, radiography and other health care degrees, education and training should be part of the curriculum and for specialists, such as radiologists, nuclear medicine specialists and medical physicists, as part of the curriculum of postgraduate degrees. The term ‘education’ usually refers to imparting knowledge and understanding on the topics of radiation health effects, radiation quantities and units, principles of radiological protection, radiological protection legislation, and the factors in practice that affect patient and staff doses. The term ‘training’ refers to providing instruction with regard to radiological protection for the justified application of the specific ionizing radiation modalities (e. Education and training are officially recognized with accreditation and certification. Accreditation and certification Organizations should be established to provide ‘accreditation’ that officially recognizes education and training on the radiological protection aspects of the use of diagnostic or interventional radiation procedures in medicine. Such organizations have to be approved by an authorizing or regulatory body, and required to meet standards that have been set by that body. A system of ‘certification’ shall be established for officially stating that an individual medical or clinical professional has successfully completed the education or training provided by an accredited organization for the diagnostic or interventional procedures to be practised by the individual, demonstrating competence in the subject matter in a manner required by the accrediting body. As the number of diagnostic and interventional medical procedures using ionizing radiations is rising steadily, and procedures resulting in higher patient and staff doses are being performed more frequently, the need for education and training of medical staff (including medical students) and other health care professionals in the principles of radiation protection will be a more compelling challenge for the future. Fostering information exchange Fostering information exchange is another key general challenge for improving radiological protection in medicine. Intergovernmental organizations, national regulatory bodies, medical professional associations, and medics and patients themselves should be part of a rich network of information exchange. This brochure underlines, on the one hand, the obvious benefits to health from medical uses of radiation, in X ray diagnostics, interventional radiology, nuclear medicine and radiotherapy, and, on the other hand, the well established risks from high doses of radiation (radiotherapy, interventional radiology), particularly if improperly applied, and the possible deleterious effects from small radiation doses (such as those used in diagnostics). This brochure describes the dilemma of protection of patients in uncomplicated prose: appropriate use of large doses in radiotherapy prevents serious harm, but even low doses carry a risk that cannot be eliminated entirely. Diagnostic use of radiation, therefore, requires methodology that would secure high diagnostic gains while minimizing the possible harm. The text provides ample information on opportunities to minimize doses and, therefore, the risk from diagnostic uses of radiation, indicating that this objective may be reached by avoiding unnecessary (unjustified) examinations, and by optimizing the procedures applied both from the standpoint of diagnostic quality and in terms of reduction of excessive doses to patients. Optimization of patient protection in radiotherapy must depend on maintaining sufficiently high doses to irradiated tumours, securing a high cure rate, while protecting the healthy tissues to the largest extent possible.

Strategy As described in the previous, vidi, chapter, the number of challenges still presented by radiological protection in medicine is enormous. In order to address these challenges and succeed in addressing them, a strategy is required. Altmaier, Federal Minister of Germany for the Environment, Nature Conservation and Nuclear Safety at the Bonn conference [2]. It did not only consider the protection of patients and their comforters but also the related and, many times, interrelated occupational protection of the medical staff attending the patients and the protection of members of the public who are usually casually exposed from medical sources. Notwithstanding this, the Bonn conference could well follow the pattern marked by the Malaga conference. Heinen-Esser, again comes to the rescue with a relevant suggestion by declaring: “I would be delighted if we were to adopt a new action programme by the end of this week and meet the shared objective of this conference: Setting the Scene for the Next Decade. It seems that the general strategy should be the achievement of a renewed international Action Plan, this time covering all aspects of radiological protection in medicine. New standards It is to be noted that there is an important framework for such a strategy and for a new action plan.

It is given in the amount of a hazelnut with lukewarm water to those suffering from apoplexy, scotomia, cephalargia, migraines, hoarseness of the voice, and chest pains; for these, it should be given with honey or gum tragacanth so that it can be toler- ated by the mouth. For those with blood-spitting conditions of the chest and disease of the lung, give it in a ptisan. For those with peripneumonia, give it with the juice or a decoction of white hore- hound. For nephritics, those suffering from stones, and cholerics, give it with a decoction of gromwell, and wild or domestic celery. For those suffering from conditions of the windpipe, give it with the juice or a decoction of meadow rue. For poisons and for bringing on the menses or the fetus, give it with warm wine, or with mulsa made with water in which mint or sweet basil has been cooked. And for those suffering from a periodic chill and all other diseases, give it with lukewarm water. It is given for pain of the stomach in men and women with water in which fennel seeds, anise, and mastic have been cooked. It is [also] given for disorder of the womb caused by frigidity if it is drunk mixed with wine in which mugwort has been cooked. It also provokes the menses if it is made with well-ground mugwort  Appendix and mixed with musk oil. A pessary made from cotton, if it has been anointed with [the trifera] and inserted into the vagina of the woman, provokes the menses in a woman who is not conceiving. If it is given with wine in which mandrake or dwarf elder has been cooked, it works in a wonderful way for chil- dren who are not able to sleep. And in the night when they chatter excessively, it works when an amount the size of a chickpea is mixed with woman’s milk and drunk. Take two drams of juice of opium poppy; one dram each of cinnamon, cloves, galangal, spikenard, zedoary, ginger, cost- mary, calamite storax, sweet flag, galingale, Florentine iris, hog’s fennel, yel- low flag, mandrake, Celtic nard, dog rose, pepper, anise, wild celery, parsley, alexanders, wild carrot, henbane, fennel, sweet basil, and cumin; and honey as needed. Trifera saracenica (¶¶, ): Trifera saracenica (otherwise known as ‘‘juve- nile’’) renders a person young again. It is given particularly for those suffer- ing from jaundice and liver problems, and to those suffering from head pain on account of a fumosity of red bile. And it restores sight lost from [excessive] heat, and it brings back lost color to its original state. Take three ounces of sugar; one ounce and a half each of the bark of citrine myrobalans, and the fleshy innards of cassia tree bark and tamarinds; six drams, two scruples, and five grains each of cleaned chebulic myrobalans and manna; one-half ounce each of Indian [myrobalan] and fresh violets if they can be found; two drams and fifteen grains each of anise and fennel; one dram and seven and a half grains each of mastic and mace; one-half ounce and four grains each of belleric and emblic. Prepare thus: in two pounds of water let there be placed three ounces of fresh violets if they can be found. Take part of the strained water, and let the cassia tree bark and the tamarinds be washed through a colander, and let them be strained through it as well. In another [container of] water, there should be put one pound and eight ounces of sugar, and let them be placed on the fire and boil until it be- comes thick: and when it begins to thicken, let the strained water of cassia tree bark and tamarinds be added, and then the manna. Then let it be taken off the fire, and when it has chilled, let Compound Medicines in the Trotula Ensemble  a powder of the above-mentioned spices be added, all the while stirring with a spatula until it is incorporated. This is given in the amount of a chestnut; if [the disease] comes from a distemperance of heat, it is given with cold water; if is comes from an abundance of a cold humor, it is given with hot water. Unguentum album (¶): Unguentum album [white unguent] [is good for] salty phlegm. The powder of white lead should be mixed with a little oil, and then added to the litharge. While stirring con- stantly with a pestle, rose water should be added a little at a time. Then it should be stored away and it should not be allowed to get too thick or too thin. Unguentum aureum (¶): Unguentum aureum [golden unguent] is good against all acute, cold gouts, and especially against kidney stones and dropsical conditions. Take two pounds each of marsh mallow root, valerian, and hog’s fennel; one pound each of both aristolochias [i. The herbs should be collected in the month of May and, having been thoroughly ground, should be put in oil or white wine for twenty days. Afterward, let oil be added as needed and let the herbs boil until they begin to dissolve and let them be strained through a sack. Then let the fats, having been well dissolved and strained, be put on top, and leave them to boil a little. Afterward let the laurel oil be poured over and, having taken [the pot] off the fire, let the other oils be added, then the powders of costmary, pellitory, and camel’s hay; then  Appendix the frankincense; then the myrrh.
