The percussion note is dull over the spleen but is (Histoplasma), parasitic (malaria, Leishmania, usually resonant over the kidney trypanosomiasis) 6. Rather, the examination for splenomegaly is most useful to rule in the diagnosis of splenomegalyamong patients in whom there is a clinical suspicion of at least 10%. If no dullness is detected on percussion, there is no need to palpate as the results of palpation will not effectively rule in or rule out splenic enlargement. If the possibility of missing splenic enlargement remains an important clinical concern, then ultrasound or scintigraphy is indicated. If both tests are positive,thediagnosisofsplenomegaly isestablished(providing theclinical suspicionofsplenomegaly wasat least10% beforeexamination).

Personal Communication Secondly it can be used to control some intestinal parasites and worms order levitra extra dosage 40mg line erectile dysfunction diet. For particularly severe infestations the dose may be repeated no sooner than 2 days after the original treatment provided a bowel movement has occurred in this period order 60 mg levitra extra dosage with visa impotence 40 year old. Nicotine is toxic and some individuals are particularly susceptible to its effects; if the patient shows indications of susceptibility to nicotine poisoning, a second dose should not be administered. Its effectiveness in clearing parasites arises from the differences in sensitivity to nicotine between man and many common parasites. The primary problem with nicotine is the effect that produces the muscle relaxation also causes toxic effects, by activation of the nicotinic receptors in the nervous system. While the amount of nicotine in cigarettes and cigars is relatively constant there is large variation in concentration in both wild and cultivated tobacco. Like with Foxglove dosing is trial and error and using cultivated tobacco as a source of nicotine is potentially very risky and should avoided except in a major catastrophe. Nicotine is also an effective insecticide and can be used as a spray on vegetables to prevent insect infestations. Cannabis (Cannabis sativa) This plant is deserving of special mention due to its widespread availability and use. Small amounts taken infrequently produce relaxation, a degree of sedation, and appetite stimulation. Several studies have demonstrated that for patients with chronic pain, nausea from cancer treatment, or muscle spasm small amounts may improve daily functioning. However, larger amounts and chronic use do have significant medical consequences, and for patients with pre-existing mental illness regular use can - 78 - Survival and Austere Medicine: An Introduction worsen symptoms. Cannabis may be of value in the same way that any pharmacologically active substance can be, but this is not an endorsement of its recreational use. Honey While not technically a plant no discussion of botanical and herbal medicine would be complete without the mention of using honey as a healing agent. This is a common item in food storage programmes, but it needs to be in your medicinal storage preparations also. Change daily, cleansing the wound area with a strong solution of Echinacea root, repack with honey, then redress sterilely. A real strong solution of Echinacea will have a numbing effect which will make the wound cleansing less painful. A tablespoon eaten every 1-2 hours for a week or so should clear up an acute condition, then a tablespoon 3 x daily for a week or so should clear up the condition entirely.

Poppy extracts provide the most practical option for managing severe pain in an austere situation. Beware: possession with the intention to use as a drug is illegal in many countries. For the majority there is very little evidence aside from anecdote to their efficacy. A common underlying principle of most alternative therapies is good nutrition and a healthy lifestyle – the value of this is clearly not in dispute. A number of alternative therapies are based on scientific theories from hundreds of years ago which have been superseded by modern science. To accept these underlying principles requires you to suspend your belief in some of the fundamental concepts of modern science and especially physics. It is vital you should take the time to look at the evidence for an alternative therapy or diagnostic modality before counting on them as a main part of your medical preparations. The weakest sort of evidence is anecdote and testimonials, and you should be very careful accepting any therapy that only has this level of evidence to support it. Conventional medicine does not have trials proving every therapy works and neither should alternative therapies by expected to either. Some things we intuitively know are correct – you do not need a randomised controlled trial to prove that a parachute is better than nothing if you are about to jump out of a plane.

For pleurisy order levitra extra dosage 60 mg amex laptop causes erectile dysfunction, it cures [if] it is first heated on the fire in an eggshell and then anointed on the chest discount levitra extra dosage 60mg without prescription biking causes erectile dysfunction. It is particularly good for people who have been poisoned and for bites from rabid dogs or other poisonous animals. It is given to drink with the juice of mint; and [the person who has been bitten] should be anointed with it directly upon the wound itself, and it should be anointed on venomous conditions, that is bonum malanum, which the Salerni- tans call scagia. For those suffering from quartan fever and for true quotidian fever, [if] given with a decoction of meadow rue or felwort, it helps. Take one ounce plus two scruples less eleven grains each of myrrh, round aristolochia, felwort, and husked laurel berries; one dram and two scruples each of fenugreek, black cumin, and zedoary; one dram, two scruples, and seven grains each of dittany of Crete, wall germander, and meadow rue; one dram each of ivy gum and burnt vitriol; one dram of Esdra magna;8 one dram each of deer heart bone, mummy, and columbine; three drams of burnt deer horn; and honey as needed. Given simply or as a laxative with warm water it marvelously purges both black bile and phlegm. It is given to epileptics with warm water, salt, and a mixture of honey and water. It cures  Appendix thosewith stomach ailments and vertiginous epileptics who foam at the mouth and bite their tongues. Given each month, as we have said, as a pur- gative, it heals paralytics suffering from trembling. Take two ounces each of colocynth and the insides of polypody; one and a half drams plus six grains each of spurge, wall germander, and laurel fruit; one ounce and twelve grains each of wormwood and myrrh; one dram each of common cen- taury, agaric, ammoniacum incense, clove, spikenard, squill, and scammony; one scruple and fourteen grains each of aloe, thyme, madder tips, cassia tree bark, wall germander, bdellium, and white horehound; half a dram each of cinnamon, opoponax, castoreum, long aristolochia, white and black and long pepper, saffron, serapinum gum, and parsley; six grains each of white and black hellebore; and honeyas needed. It is made for various diseases of the head, or diseases of the ears or distemper of the eyes. It relieves disorders of the liver, and it removes and thins out hardness and density9 of the spleen. It is good for the kidneys and the bladder, and it cleanses distemper of the womb. Take two scruples each of cinnamon, spikenard, saffron, camel grass, hazelwort, cassia tree bark, balsam wood, balsam fruit, violet, wormwood, agaric, roses, vegetable tur- peth, colocynth, and mastic; aloe in the weight of all the spices, i. Its dose is three drams, [to be given] with warm water in the morning while fasting. If, however, you make pills, give fifteen or seventeen of them with a sufficient amount of scammony. Oleum rosaceum (¶¶, , , , , , , , ): Oleum rosatum has a cold and styptic power and thus is the best thing for head pains from fever or from the heat of the sun. Moreover, it takes away burning and heat when the stomach is full of bile [and when] its windiness fills the whole head or just part of it. It is good for those pains which happen sometimes in the whole head or part of it if the head is anointed with this. It also is good for pains arising Compound Medicines in the Trotula Ensemble  in the stomach or intestines from sharpness of the humors if it is mixed with two drams of mastic and enough wax dissolved in it and then anointed on the affected parts. It is useful against erysipelas that does not appear on the surface [of the skin] and for many other conditions of this kind. One and a half pounds of slightly crushed fresh roses should be placed in two pounds of common (and in our opinion, cleaned) oil; these should be placed in a full pot suspended in a cauldron full of water. And let these boil for a while until they are reduced to a third of their original quantity. Only then should this be put into a white linen cloth and squeezed through a press. In the same manner oil of elder, violet, and sweet gale is made, that is, those oils which are good in acute diseases; anointed on the liver, pulse points, temples, and palms of the hands and soles of the feet, they extinguish heat completely. Oxizaccara (¶): Oxizaccare is so called from oxi, which is vinegar, and zu- charo, ‘‘sugar. Take one pound of sugar, eight ounces of pomegranate juice, and four ounces of vinegar, and place in a tin10 vessel on the fire. And let it boil for a while, stirring constantly with a spatula, until it is reduced back to the quantity of the sugar; it should become so thick that it can be carried. It is called Paulinum because it is large, antidotum because it is given as an antidote, for it has great power and efficacy. Properly, it is given for chronic and acute coughing, which arises from a flow- ing out of rheum from the head. It is good for disorders of the chest caused by cold [when given] in the evening with warm wine.

Obvious examples are alive or dead proven 60 mg levitra extra dosage impotence quoad hoc, yes or no cheap levitra extra dosage 40 mg on line impotence gels, normal or abnormal, and better or worse. This has the effect of dichotomizing the value of the serum sodium into either hypernatremic or not hypernatremic. Measurement in clinical research All natural phenomena can be measured, but it is important to realize that errors may occur in the process. Random error leads to a lack of precision due to the innate variability of the biological or sociological system being studied. For example, in a given popula- tion, there will be a more or less random variation in the pulse or blood pres- sure. Many of these random events can be described by the normal distribution, which we will discuss in Chapter 9. An imprecise instrument will get slightly different results each time the same event is measured. For example, serum sodium measured inside rat muscle cells will show less random error than the degree of depression in humans. There can also be innate variability in the way that 70 Essential Evidence-Based Medicine different researchers or practicing physicians interpret various data on certain patients. Systematic error represents a consistent distortion in direction or magni- tude of the results. Systematic or systemic error is a function of the person making the measurement or the calibration of the instrument. For example, researchers could consistently measure blood pressure using a blood-pressure cuff that always reads high by 10 mmHg. More commonly, a measurement can be influenced by knowledge of other aspects of the patient’s situation lead- ing to researchers responding differently to some patients in the study. Another source of systematic error can occur when there is non- random assignment of subjects to one group in a study. For instance, researchers could preferentially assign patients with bronchitis to the placebo group when studying the effect of antibiotics on bronchitis and pneumonia. This would be problematic since bronchitis almost always gets better on its own and pneu- monia sometimes gets better on its own, but it is less likely and occurs more slowly. Then, if the patients assigned to placebo get better as often as those tak- ing antibiotics, the cause of the improvement is uncertain since it may have occurred because the placebo patients were going to get better more quickly anyway. The researcher’s job is to minimize the error in the study to minimize the bias in the study. Researchers are usually more successful at reducing systematic error than random error. Overall, it is the reader’s job to determine if bias exists, and if so to what extent and in what direction that bias is likely to change the study results. Instruments and how they are chosen Common instruments include objective instruments like the thermometer or sphygmomanometer (blood-pressure cuff and manometer) and subjective instruments such as questionnaires or pain scales. By their nature, objective measurements made by physical instruments such as automated blood-cell counters tend to be very precise. However, these instruments may also be affected by random variation of biological systems in the body. An example of this is hemodynamic pressure measurements such as arterial or venous pres- sure, oxygen saturation, and airway pressures taken by transducers. The actual measurement may be very precise, but there can be lots of random variation around the true measurement result. Subjective instruments include questions that must be answered either yes or no or with an ordinal scale (0, 1, 2, 3, 4, or 5) or by placing an x on a pre-measured line. Measures of pain or anxiety are Instruments and measurements: precision and validity 71 common examples and these are commonly known to be unreliable, inaccurate, and often imprecise. Overall, measurements, the data that instruments give us, are the final goals of research. They are the result of applying an instrument to the process of sys- tematically collecting data. Common instruments used in medicine measure the temperature, blood pressure, number of yes or no answers, or level of pain.
