This is evident from what often happens during sleep: people think that it is lightning and thundering purchase keppra 250 mg otc, when there are only faint sounds in their ears buy discount keppra 250 mg on-line, and that they are enjoying honey and sweet flavours when a tiny bit of phlegm is running down their throats keppra 250mg for sale, and that they go through a fire and are tremendously hot when a little warmth is occurring around certain parts of the body cheap 250mg keppra. But when they wake up buy keppra 250mg cheap, they plainly recognise that these things are of this nature. Consequently, since of all things the beginnings are small, it is evident that also of diseases and of other affections which are going to occur in the body, the beginnings are small. It is obvious, then, that these are necessarily more clearly visible in sleep than in the waking state. If the dream is correctly interpreted, it can be reduced to its cause, which can be recognised as the cause of an imminent disease. Aristotle pays no attention to the rules for such a correct interpretation of dreams; he only analyses the causal structure of the relationship between the dream and the event foreseen in it. The first is one of the corner stones of his theory of dreams as set out in On Dreams (460 b 28ff. This principle is demonstrated by means of a number of examples derived from common experience (no. The second principle is that the origins of all things (including diseases) are small and therefore belong to the category of small movements. The two principles are combined in the form of a syllogism at the end of the paragraph. These points are most relevant for an assessment of what Aristotle is do- ing in the passage under discussion. It has, of course, long been recognised by commentators that the sentence 463 a 4–5 may very well be a reference to the Hippocratic treatise On Regimen, the fourth book of which deals with dreams and which I quoted at the beginning of this chapter. Although the Hippocratic Corpus contains several examples of the use of dreams as prognostic or diagnostic clues,49 we nowhere find such an explicit theoret- ical foundation of this as in this book. It is chronologically possible and plausible that Aristotle knew this treatise, because other places in the Parva naturalia show a close similarity of doctrine to On Regimen. Moreover, the author’s approach must have appealed to Aristotle for the very fact that the interest of dreams is that they reveal the causes of diseases. However, these similarities should not conceal the fundamental differ- ence of approach between the medical writer and Aristotle. This difference not only manifests itself in that Aristotle, as a natural scientist, is only inter- ested in the causal relationship between the dream and the event, whereas On Regimen is primarily a text about regimen (both from a preventive and from a therapeutic point of view), which explains the great amount of de- tailed attention paid to the interpretation of the contents of dreams and to prescriptions about preventive dietetic measures. The most important difference lies in the psycho-physiological explanation of the significance of dreams given by the two authors. The author of On Regimen appeals to a rather ‘dualistic’ conception of the relation between soul and body, of the type referred to earlier on in this chapter: 49 SeetheinstanceslistedinvanderEijk(1994)279. Ross (1955) 56–7, who points out that Aristotle’s ‘comparison of the heart-lung system to a double bellows [in De respiratione 480 a 20–3] is clearly borrowed from Vict. Aristotle on sleep and dreams 199 For when the body is awake, the soul is its servant: it is divided among many parts of the body and is never on its own, but assigns a part of itself to each part of the body: to hearing, sight, touch, walking, and to acts of the whole body; but the mind is never on its own. However, when the body is at rest, the soul, being set in motion and awake, administers its own household and of itself performs all the acts of the body. For the body when asleep has no perception; but the soul, which is awake, cognises all things: it sees what is visible, hears what is audible, walks, touches, feels pain, ponders, though being only in a small space. Whoever, therefore, knows how to interpret these acts correctly, knows a great part of wisdom. It would be impossible for Aristotle to say – as the writer of On Regimen does – that in sleep the body is at rest but that the soul works. Sleep is for Aristotle an affection of the complex of soul and body due to the heating and cooling of food and preventing the animal from perceiving actual sense movements. It is obvious, therefore, that we cannot say that Aristotle is influenced here by the medical writer’s views on dreams. It would be more appropriate to say that the non-specialised student of nature gives a theoretical explanation or even a justification of the view held by the distinguished doctors; this justification is given entirely in Aristotle’s own terminology and based on his own presuppositions (the two principles mentioned above). This procedure is completely in accordance with his general views on the relation between natural science and medicine discussed above. However, the incorporation of the medical view on the prognostic value of dreams into his own theory of sleep and dreams does confront Aristotle with a difficulty which he does not seem to address very successfully. For, as we have seen above, in On Dreams Aristotle says that dreams are based on the remnants of small sensitive movements which we receive in the waking state but do not notice at the time, because they are overruled by more powerful movements which claim all our attention. Yet during sleep, when the input of stronger competing sensitive movements has stopped, the remnants of these small movements come to the surface and present themselves to us in the form of dreams. As I have already said, it is exactly this mechanism to which Aristotle seems to refer in Div.

Bicipital tendonitis is produced by friction on the tendon of the long head of the biceps as it passes through the bicipital groove purchase 500mg keppra with mastercard. Patients experience anterior shoulder pain that radiates down the biceps to the forearm generic 500 mg keppra overnight delivery. Five to 10% of patients with psoriasis will develop an arthritis associated with the rash keppra 250mg without prescription. However generic keppra 250 mg overnight delivery, another 15 to 20% of patients will have joint complaints as the presenting symptom of their psoriasis generic keppra 500mg overnight delivery. Erosive joint disease ultimately develops in almost all these patients, and most of them become disabled. Changes that are frequently seen include pitting, horizontal ridging, onycholysis, yellowish discoloration of the nail margins, and dystrophic hyperkeratosis. Thus, in patients with joint symptoms that pre- cede the onset of rash, the diagnosis is frequently missed until dermatologic or nail changes develop. A family history of psoriasis is important to ascertain in any patient with an undiagnosed inflammatory polyarthropathy. Radiog- raphy may show typical changes, particularly in patients with arthritis mutilans. Other treatments include methotrexate, sulfasalazine, cyclosporine, reti- noic acid derivatives, and psoralen plus ultraviolet light. The peak age of onset is in the for- ties to fifties, but it may occur at all ages. Approximately 30% of patients will have an- other rheumatologic disorder, most commonly systemic vasculitis. Auricular chondritis is the most common clinical manifestation of relapsing polychondritis, occurring 43% of the time as the presenting complaint, and with 89% cumulative frequency. Aortic regurgitation, due to dilation of the aortic ring or de- struction of the cusps, is an uncommon finding in this illness, occurring in ≤5% of cases. The diagnosis of relapsing polychondritis is based on recognition of the characteristic clinical features, including two or more separate sites of cartilaginous inflammation that responded to treatment with prednisone or dapsone. Biopsy can confirm the diagnosis but may not be necessary if the clinical features are typical. The primary non-Hodgkin’s lymphoma associated with Sjögren’s syndrome is a low-grade, marginal zone B cell lymphoma that usually presents extranodally. Persistent parotid enlargement, leukopenia, cryoglobulin- emia, and presence of rheumatoid factor should prompt evaluation for possible lymphoma. Treatment for Sjögren’s syndrome should be same as that for other B cell non-Hodgkin’s lymphomas. Factors that influence survival include size >7 cm, pres- ence of B symptoms, and high or intermediate histologic grade. Adenoid cystic carci- noma is the second most common malignant tumor of the salivary glands after mucoepidermoid carcinoma, but it does not occur more commonly in Sjögren’s syn- drome. An impacted sialolith could cause unilateral enlargement of the parotid gland but should present with pain with palpation. Pain is worse with eating or the anticipation of eating, which would stimulate saliva production. The ulcer- ations are generally painful, occur in groups, and subside spontaneously in 1–2 weeks without leaving scars. The diagnosis requires the presence of recurrent oral ulcers plus two of the fol- lowing criteria: recurrent genital ulcers, eye lesions, skin lesions (including erythema nodosum), or positive pathergy test. A pathergy test is considered positive when nonspe- cific skin inflammation develops 2–3 days after a scratch or injection of sterile saline. Other clinical manifes- tations of Behçet’s syndrome include nonerosive arthritis, gastrointestinal ulcerations, and neurologic involvement. In addition, individuals with Behçet’s syndrome are at in- creased risk of venous thromboembolic disease. It is more common in individuals from the Mediterranean region, Middle East, and Far East. In advanced disease, antibodies to α-enolase of endothelial cells and Sac- charomyces cerevisiae have been shown. The pathologic lesion is perivasculitis with neu- trophilic infiltration, endothelial swelling, and fibrinoid necrosis. Oral and genital lesions can usually be treated with topical glucocorticoids alone. Other treatments that are effec- tive include thalidomide, colchicine, and systemic glucocorticoids.
