Next comes the sympathetic nervous system cheap 30 mg procardia free shipping heart disease vs congestive heart failure, which accelerates the vegeta- tive functions of the body discount procardia 30mg with amex coronary artery x rays. The study of the parasympathetic nervous system is based on the dimension of the pupil, its off-centering (if any), a possible flatness that would indicate the reflective mark of the defec- tive organ, or ovalization. According to iridologists, analyzing the iris enables us to define our physical constitution and our fundamental heredity. The fibrillary lymphatic constitution, which includes blue eyes and all the variations. The pigmentary hematogenous constitution, which is condu- cive to circulatory problems, to obesity and diabetes, to liver and kid- ney trouble, and nervous spasms of the digestive system. Like the homeopath, the iridologist studies the morbid diatheses (congenital predispositions to certain diseases). This encompasses a whole range of problems that successively or simultaneously might be- fall the same subject, problems that differ as to where they strike and what symptoms they produce, but supposedly are identical in nature. The diathesis implies an overall unity of the disease and its causes, in spite of its various somatic manifestations. The patient is often optimistic, enthusiastic, and passionate, but may evolve toward asthenia; 2. The subject is pessimistic, careful, sparing, is more prone to reflection than to action, with infec- tious tendency; 3. The patient is prone to nervous hy- pertension, anxiety, aerophagia, and aerocolics; 4. This is the ideal breeding ground for the major diseases of our civilization: tuberculosis, nervous disorders, mul- tiple sclerosis, Parkinsons, suicide. Iridology thus should make it possible to establish a complete panorama of the individual’s vital potential, his heredity, morbid pre- 2 dispositions, imbalances and deficiencies. However, a simple examination of iridology theories shows that this is, in fact, a diagnostic technique worthy of Molière’s Diafoirus. That does not prevent iridology from claiming to be a natural out- growth of classical medicine and from claiming that its origins date back to "before 1000 BC"; and that it is "in agreement with genetics and embryology". In that remote era, man contemplated the sky, he observed nature and the various relations that exist between beings, things, and events. These observations led him to note that there is a correspon- dence between the human body, divided into twelve parts, and the twelve signs of the zodiac; thus the laws of the earth and the heavens were interpenetrating, and the man of remote times looked into the eyes to assess the state of someone’s health. But when it came to objective criticism, iridology has had to adapt: Today it proclaims that these iridal messages do not always show up. They precede the disease, but not always; they are expressed only at certain ages of life and are not permanent. Predisposition is not the obligatory sign of a disease; iridal signs persist after recovery, and 4 there are diseases that are not matched by iridal signs. These sentences, drawn from one of the bibles of iridology, amount to a proclamation that the diagnosis of a disease does not mean that the disease exists; that the existence of the disease does not neces- sarily involve the presence of signs in the iris; and moreover that disease is not synonymous with signs. W hat are we to think, then, of a diagnostic method that is both inconsistent and liable to induce both negative and positive false read- ings? They bring into the equation sources borrowed from esotericism, astrology and embryology to defend their territory. Personally, I prefer a kind of therapy that seems more healthy, to me: reading the work of my friend Henri Broch, Au Coeur de l’extraordi- 5 naire [At the heart of the extraordinaire]. He makes mincemeat of the cosmo-esoteric-egypto-astrological delusions and their offshoots, which serve as both the building blocks and the peers of iridology doc- trines. Auriculo-Therapy Auriculo-therapy (ear acupuncture) is just as popular, and as ill- founded, as iridology. The same esoteric, astrological, and em- bryologic sources underlie both practices. Astrology is less influential in auriculo-therapy, but that may be simply because the anatomy of the ear does not lend itself to being cut into sections; but the esoteric and embryologic talk are the same. Here, the theory is that the outer ear (auricle) is a model of an up- side-down fetus, in which various points match up with parts of the patient’s body. The ear is checked for tender or sore points, and then an attack on a given organ is treated by acupuncture of the correspond- ing auricular zone where it is projected. The size of the area covered by the different zones is not proportional to the organ’s importance. But perhaps that is only an empirical observation, related to the size of an auriculothera- pist’s brain.

The sad reality is that the patient with back pain is a prisoner of pervasive fear—and fear is a prime perpetuator of the pain syndrome procardia 30mg sale heart disease old age. Coping I have heard it said that people get stress-induced pain because they can’t cope 30 mg procardia with visa cardiovascular workouts at home. Coping requires that we repress emotions that might interfere with whatever we are trying to do and TMS exists in order to maintain repression of those emotions. Someone I saw recently, a high-powered businessman, told me that he can never say no to friends and family who ask him to do things for them because saying no to him means defeat. Saying yes, and going ahead and accomplishing what he was asked to do, is like winning, no matter what it may cost him emotionally. This also illustrates some of the other characteristics of the TMS personality: the need to be loved, admired, respected; the drive to achieve; and the intense competitiveness. We pay a price for coping—we’re 56 Healing Back Pain great on the outside and we suffer on the inside. Rejecting the Diagnosis It is an unfortunate fact that most people would reject the diagnosis of TMS if it were presented to them. This is not surprising, for there remains a strong prejudice in our society regarding anything having to do with psychological problems and psychotherapy. It doesn’t matter that the overwhelming majority of such “problems” are minor or that millions of people have psychotherapy every year. Emotional difficulties appear to fall into the same category as racial and religious prejudice. Judging from the politics of running for public office, the events of recent years suggest that society has done better in overcoming its racial and religious phobias than it has with psychology. But we have learned from the electoral process in recent years that any hint of a psychological history is still the kiss of death for someone running for high public office. Cruel paradox, for the contemporary political scene suggests that many politicians would profit greatly from psychotherapy. Under the circumstances it is very unlikely that a politician would acknowledge having TMS. Similarly, most athletes would reject the diagnosis since psychological syndromes are equated with weakness, and athletes have an image of strength and indomitability to preserve. Doctors prefer to treat physical disorders; they feel insecure when confronted with patients who have emotional symptoms. Their usual response is to prescribe a medication and hope that the patients will feel better. Even the field of psychiatry now has a large segment of practitioners who prefer to treat primarily with drugs. And I know of a number of psychiatrists who rejected the concept The Psychology of TMS 57 of TMS when it was suggested as a possible explanation for their back pain. On the other hand, people with physical symptoms rarely encounter such prejudices. Medical insurance will pay for the most elaborate diagnostic and therapeutic procedures but most policies exclude or sharply limit payment for psychotherapy. Thousands of dollars will be given for an organ transplant to preserve life but peanuts assigned for therapy that will improve the quality of life. Little wonder that the mind develops strategies to avoid the experience and appearance of emotional difficulty. Unconsciously, we would rather have a physical pain than acknowledge any kind of emotional turmoil. She said, “If you ask people to ease up on you because you’re emotionally overloaded, don’t look for a sympathetic response; but tell them you’ve got pain or some other physical symptom and they immediately become responsive and solicitous. It is perfectly acceptable to have a physical problem in our culture, but people tend to shy away from anything that has to do with the emotions. It is one more reason why the mind will choose a physical rather than an emotional manifestation when confronted with unpleasant emotional phenomena. From time to time I have been asked if there are people anywhere in the world who don’t get TMS. Kirkaldy-Wallis, a British-trained physician who worked in Kenya for twenty-two years, provided the answer. He reported at a medical meeting in 1988 that back pain was very rare in indigenous Africans but was just as common in Caucasians and Asians as it is in the United States and Canada. He attributed this partly to cultural differences, positing that Africans didn’t seem to generate anxiety as we do.

Until further data are avail- able procardia 30 mg on line cardiovascular warm up, the choice between these tests will be largely dependent on physician preference and available resources buy procardia 30 mg online arteries carry blood away. These injuries are most frequently seen in young males and are usually precipitated by sports (36%); twisting, bending, or stepping motions (27%); or falls (21%) (1). One community survey in the United Kingdom found that 19% of adults reported knee pain lasting more than 1 week in the previous month and 16% reported shoul- der pain (4). Prevalence in both sexes rose steadily with age, reaching a plateau at about age 65 and was also positively associated with social deprivation. Although the prevalence is high, many people with knee or shoulder pain do not seek medical care (5). Overall Cost to Society In the year 2001, knee symptoms and injuries were the primary reason reported by the patient for 1. Knee prob- lems, therefore, are in the top 15 most frequent reasons for consulting a physician, second only to back pain among musculoskeletal problems. Chapter 15 Imaging for Knee and Shoulder Problems 275 For knee and shoulder problems seen in outpatient settings, imaging uti- lization varies greatly by specialty. A study conducted in the United States observed that orthopedic surgeons requested radiography in 80% of first knee pain consultations and 78% of first shoulder pain consultations, whereas rheumatologists utilized radiography in far fewer knee (45%) and shoulder (36%) cases (8). Orthopedic surgeons were also more likely to refer for MRI of the knee (20% versus 6%) and, to a lesser extent, of the shoulder (4% versus 2%). The direct cost of health care for musculoskele- tal problems is about 1% of gross national product in several industrial- ized countries (9), although we found no convincing estimates of the total societal costs for knee and shoulder problems. Goals Among patients who seek medical attention for knee and shoulder prob- lems, the clinician’s task is to find the appropriate balance between phys- ical examination, diagnostic imaging, and arthroscopic investigation to achieve accurate diagnosis and initiate cost-effective therapy. Methodology Our initial search strategy identified systematic literature reviews of knee and shoulder imaging studies. We searched the Medline database using the PubMed interface for abstracts published between January 1966 and March 2004 with the search words knee and shoulder and the PubMed designation of a systematic review (systematic [sb]). From this group, we selected several key arti- cles reviewing the role of imaging (10–19). We then searched the articles cited by these systematic reviews to identify the relevant primary studies. For topics where no recent systematic review was available, we selected two seminal articles on the topic and searched for similar work using the related articles PubMed function. Where possible, we obtained and reviewed the full text of all relevant English-language articles identified. What Is the Role of Radiography in Patients with an Acute Knee Injury and Possible Fracture? Summary of Evidence: Acute knee trauma provides a common diagnostic quandary in accident and emergency departments. Fractures are present in 4% to 12% of patients presenting with knee injuries (20,21), and yet radi- ography may be requested in excess of 70% of cases (22). Several guide- lines are available to help clinicians target imaging at high-risk patients. There is strong evidence (level I) to suggest that the five criteria of the Ottawa knee rule (OKR) are highly sensitive at predicting fractures in adults and moderate evidence (level II) that this rule can be generalized to children older than 5 years of age. Further work is needed to evaluate the impact of the OKR on the cost-effectiveness of medical care. Supporting Evidence: Several groups have developed clinical decision rules to guide knee radiography requests following trauma in order to save costs 276 W. These decision rules focus var- iously on patient age, injury mechanism, inability to ambulate, and other clinical signs such as fibula head tenderness. The optimal threshold for radiography requests depends on the trade-off between the clinical and possible legal consequences of a missed fracture compared to the time, cost, and radia- tion exposure of radiographs. In practice, all of the decision rules place great emphasis on sensitivity at the expense of specificity. Other decision rules may have greater specificity, but they have not yet been validated by independent investigators.

An elastic string of negligible weight and length L was attached to stationary points A and B (Fig generic procardia 30mg with amex braunwald heart disease 9th edition download. The string was just about tight in the horizontal position buy procardia 30mg cardiovascular system symptoms, carrying virtually no tension. When a weight W was attached to the mid- point of the string, the two halves of the string made an angle u with the horizontal axis. Solution: The condition of force balance in the vertical direction requires that 2W 1 2T sin u 5 0 T 5 W/(2 sin u) (5. Equations of static equi- librium are not sufficient to determine these parameters, and thus this simple system is statically indeterminate. We consider the material prop- erties of the string to come up with an additional equation. Hooke’s law dictates that T 5 E (D/L) A in which E is the Young’s modulus of the string, A is its cross-sectional area, and D is the extension of the string AB. Using trigonom- etry we can show that (D/L) 5 (L/cos u 2 L)/L 5 (1 2 cos u)/cos u T 5 EA(1 2 cos u)/cos u (5. The rod AB of length 4a is tied to stationary points through two inextensible strings (Fig. These strings all have the same cross-sectional area A and the same Young’s modulus E. Rod AB of length 4a is attached to stationary points through two in- extensible strings. Statics Solution: The free-body diagram of point C shown in the figure requires that T1 1 2T2 cos u 1 2T3 cos f 5 W (5. Let D be the vertical displacement of point C in the direction of the gravitational force W. We assume that the strings are stiff so that D is small in comparison with the lengths of the strings. The extension of each of the elastic strings can then be defined as a func- tion of D: D1 5D D 5 [a2 1 (h 1D)2]0. D cos f 3 Thus, the strains in the strings are e1 5D1/h 5D/h e 5 (D/h) cos2 u 2 e 5 (D/h) cos2 f 3 We can express the tension in each string in terms of the strain: T1 5 E A (D/h) T 5 E A (D/h) cos2 u 2 T 5 E A (D/h) cos2 f 3 Substituting these values into Eqn. In actual life, most loads acting on objects are distributed over a surface or a volume. For example, snow load (kg/m2) is a distributed surface load whereas gravity acts throughout the body of an object. The internal stress in a body may depend strongly on the specific distribution of external 5. For example, the soles of shoes are designed to more uniformly distribute ground forces on the base of the foot so as to avoid stress frac- ture or soft tissue damage. Point forces lead to different internal stresses than distributed forces of the same magnitude and direction, at least in a small region surrounding the point of application of the force. In the study of motion and equilib- rium of a stiff solid body, however, it is sufficient to replace distributed loads with a single force and or moment. Two-force systems are said to be statically equivalent if (a) the resultant force vectors are equal, and (b) the resultant moment of one force system with respect to a point in space is equal to that of the other. This equivalency relationship reflects the fact that when a force is moved up or down along its line of action, its effect on the motion of the body is not altered. Note that X also repre- sents the horizontal distance from point O to the centroid of the area oc- cupied by the distributed load. The equivalent force system to a distributed load need not be a point force, but it could be a force couple. A couple is composed of two forces that are equal in magnitude but opposite in direction. Statics do not share the same line of action, they exert a moment on the object but no resultant force. The axial stress distribution on the cross section of the cantilever beam of Example 5. Thus, the condi- tions of equilibrium are SF 5 0 and SM 5 0 The moment M of a force F about point O is defined as M 5 r 3 F Although static analysis is strictly valid for objects in equilibrium, it could provide reasonable approximations for the forces involved in mo- tions with small accelerations.
