When medieval translators looked for gyne- cological material to render into the vernacular generic caverta 50mg with amex treatment for erectile dysfunction before viagra, it was to the Trotula texts that they most frequently turned 50mg caverta with mastercard doctor for erectile dysfunction in ahmedabad. Of ten gynecological texts composed in Middle English between the fourteenth and ﬁfteenth centuries trusted 100mg caverta erectile dysfunction pumps cost, for example, ﬁve are renditions of the Trotula. The Latin texts probably only rarely made their way into women’s hands in the early years after their composition, perhaps not at all after the thirteenth century. The Laon manuscript just mentioned, for example, passed from that anonymous male surgeon into the holdings of the cathedral of Laon, where it was annotated and used by the canons of the cathedral for the rest of the Middle Ages. Every other manuscript whose provenance is known is similarly found passing exclusively through the hands of men. Its early provenance is not known, but it has the distinction among the Latin Trotula manuscripts in being the smallest codex, a handbook less than six by four inches in size. It also contains only one other text: a brief tract on useful and harmful foods, which could, conceivably, be used for self-medication by controlling diet. There are no contemporary annotations to conﬁrm owner- ship by a woman, but its small size (similar to that of the books of hours owned by many upper-class women in this period) and the absence of any other, more technical medical literature may suggest use by a layperson and so, perhaps, by a woman. The author of the earliest English translation, writ- ing in the late fourteenth or early ﬁfteenth century, went so far as to demand of any male reader who happened upon the text that ‘‘he read it not in spite nor [in order to] slander any woman nor for any reason but for healing and helping them. It seems, then, that relative to their widespread popularity among male practitioners and intellectuals, it was only very infrequently that the Trotula found their way into the hands of women. Despite the recognition by the author of Conditions of Women that women often did not want to turn to male physicians, the Trotula seem to have functioned as a prime tool by which male practitioners did, in fact, come to have signiﬁcant control over the practice of gynecology and cosmetics. Note on This Edition and Translation T E The following edition of the Trotula ensemble represents the standardized text as it circulated in the latter half of the thirteenth century through the turn of the fourteenth century. The nine manuscripts collated here were chosen on the basis of their early date and the integrity of their text. The text, including orthography, reﬂects that of the Basel manuscript, including the hand of the original scribe (B), that scribe’s own corrections (B1), and the corrections of a second, slightly later hand (B2). I have deviated from B’s text only in those cases where the orthography seemed misleading, or where the unanimous agreement of the other manuscripts suggested a lacuna or an error in B. Where B’s reading is unique but not necessarily erroneous, however, I have retained it despite the unanimity of the other manuscripts. All variants are noted in the apparatus with the following two exceptions: varia- tions in word order and orthography, except in those cases where they seemed potentially meaningful, and the presence orabsence of et except, again, in those cases where it might be important to the sense. Corrections or expunctions in the hand of the original scribes have not been specially ﬂagged; the text has simply been read as corrected. It is meant not only to indicate the obvi- ous grammatical and topical breaks (and in this I have respected the manu- scripts’ readings as much as possible) but also to reﬂect the original compo- nent parts of the texts. Thus, strings of recipes will often be separated except in those instances (such as ¶) where they all come uninterrupted from a single source. More detailed information on when, exactly, this material entered the ensemble and on internal transpositions of material within the texts can be found in my essay on the subject. B’s orthography displays certain Italianate features, such as a characteristic doubling of consonants (e. The text has been carefully corrected by a contemporary hand (B2), who notes a few omissions in the margins or interlinearly. The original scribe entered the text of the rubrics at the bottom of the page; these were then written in by the same hand.

Many rubrics illegible on ﬁlm; upper parts of several folios damaged by water or acid, thus occasionally obscuring the text of the top – lines.

T T In the translation that follows, I have aimed for clarity above all. I have resisted the temptation to ‘‘diagnose’’ the conditions described and have preferred to replicate the sometimes loose phrasing of the Latin rather than oﬀer more pre- Introduction cise readings that presume the ideological framework of modern western bi- ology and medicine. Readers can decide for themselves if, for example, they wish to interpret infertility accompanied by dry lips and incessant thirst (¶) as a description of diabetes. I have also retained the grammatical voice of most instructions—that is, I have rendered passive constructions passivelyand active actively. Although admittedly this results in a somewhat uneven text, it has the virtue of reﬂecting some remnants of the distinctive tone of address of the three original texts. On the one hand, the names used by the authors of the origi- nal Trotula texts in twelfth-century southern Italy often became deformed in transmission (I have ﬂagged only the major deviations in the notes to the edi- tion), or they may have referred to several diﬀerent plants. Some species may now be extinct or their chemical properties may have changed slightly over the past eight hundred years. On the other hand, there are instances when mul- tiple Latin names seem to refer to the same plant, for example, altea, bismalua, euiscus, malua, and maluauiscus, all of which seem to refer to marsh mallow (Althaea oﬃcinalis L. Having said this, I also feel my objective as translator is to attempt to bring a world long since disappeared back to life for the reader. This, it seems to me, can best be accomplished byattempting to identify plants, animals, and other materia medica by signiﬁers we use today. Since I am neither a botanist nor a phytopharmacologist, I have availed myself of the work of linguists and historical botanists in translating the medieval Latin terms with modern English common names (and, for the sake of readers whose native language may not be English, in cross-identifying those common names with their Linnaean classiﬁcations in the Index Verborum). Any investi- gators, either historical or pharmaceutical, who wish to use these texts as the basis for scientific research should refer to the Latin text. Needless to say, I can in no sense endorse the therapeutic use of these prescriptions by lay readers.
This occurs because of the desire on the part of the physi- cian not to miss an important disease caverta 50mg line impotence with beta blockers. Therefore buy caverta 50mg line erectile dysfunction symptoms, each disease should be con- sidered by itself when determining the probability of its occurrence order caverta 50 mg erectile dysfunction over 80. This proba- bility takes into account how much the history and physical examination of the patient resemble the diseases on the differential diagnosis. The assigned proba- bility value based on this resemblance is very high, high, moderate, low, or very low. In our desire not to miss an important disease, probabilities that may be much greater than the true prevalence of the disease are often assigned to some diagnoses on the list. Physicians must take the individual patient’s qualities into consideration when assigning pretest probabilities. For example, a patient with chest pain can have coronary artery disease, gastroesophageal reﬂux disease, panic disorder, or a combination of the three. In general, panic disorder is much more likely in a 20- year-old, while coronary artery disease is more likely in a 50-year-old. When con- sidering this aspect of pretest probabilities, it becomes evident that a more real- istic way of assigning probabilities is to have them reﬂect the likelihood of that disease in a single patient rather than the prevalence in a population. This allows the clinician to consider the unique aspects of a patient’s history and physical examination when making the differential diagnosis. Constructing the differential diagnosis The differential diagnosis begins with diseases that are very likely and for which the patient has many of the classical symptoms and signs. Next, diseases that are pos- sible are included on the list if they are serious and potentially life- or limb- threatening. These are the active alternatives to the working diagnoses and must be ruled out of the list. This means that the clinicians must be relatively certain from the history and physical examination that these alternative diagnoses are not present. Put another way, the pretest probability of those alternative diseases is so vanishingly small that it becomes clinically insigniﬁcant. If the history and physical examination do not rule out a diagnosis, then a diagnostic test that can reliably rule it out must be performed. Diseases that can be easily treated can also be included in the differential diagnosis and occasionally, the diagnosis is con- ﬁrmed by a trial of therapy, which if successful, conﬁrms the diagnosis. Last to be included are diseases that are very unlikely and not serious, or are more difﬁcult and potentially dangerous to treat. These diseases are less possible because they 224 Essential Evidence-Based Medicine Fig. A good example of this would be a patient with chest pain and no risk factors for pulmonary embolism who has a low transcu- taneous oxygen saturation. Now one should begin to look more closely for the diagnosis of pulmonary embolism in this patient. When considering a diagnosis, it is helpful to have a framework for consid- ering likelihood of each disease on one’s list. This only helps to get an overview and does not help one determine the pretest probability of each disease on the differential diagnosis. In this schema, each disease is considered as if the total probability of disease adds up to 100%. One must tailor the probabilities in one’s differential diagnosis to the individ- ual patient. Bear in mind that a patient is more likely to present with a rare or unusual presentation of a common disease, than a common presentation of a rare disease. As stated earlier, 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.

Useful schema for assigning pretest (a-priori) probabilities Pretest probability Action Interpretation <1% Off the list – for now. 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.
