It covered hospital and physician services (Part A and B) menopause foggy brain 100mg lady era for sale, which included coverage of inpatient drugs and drugs administered by a physician zoloft menstrual cycle discount lady era 100 mg without prescription. The Balanced Budget Act of 1997 created an option for Medicare beneficiaries to breast cancer her2 positive buy 100mg lady era receive insurance coverage from private health plans that contract with Medicare (Part C)-these plans are currently referred to as "Medicare Advantage Plans. In 2010, the standard benefit package is $310 deductible; 25 percent coinsurance up to $2,830 of total drug costs; no coverage from $2,830 to $6,330 of total drug costs-a coverage gap that is commonly referred to as the "doughnut hole," which, starting in 2010, will be partially subsidized (beneficiaries will receive a $250 rebate); 4 and 5 percent coinsurance, or a flat copayment of $2. Second, plans can use a tiered formulary structure to create financial incentives for 4 the Patient Protection and Affordable Care Act of 2010 (P. Starting in 2011, Medicare and manufacturers will phase-in subsidies for generic and brand drugs with the goal of reducing out-of-pocket expenditure in the doughnut hole in 2010 to the same 25 percent coinsurance that applies to costs below the lower threshold of the coverage gap. Pharmacopeia has developed a therapeutic classification system that serves as a guideline for Part D formularies. We calculated the "plan coverage rate" for a particular drug as the percentage of plans that cover the drug. For each drug we calculated the "tier placement rate" as the percentage of plans that cover that drug on a given tier. For example, if 20 percent of the plans that cover a drug have placed that drug on tier 4, the drug has a tier 4 placement rate of 20 percent. A few plans have more than four tiers-for these plans we included all tiers greater than four in the tier 4 category. These categories are subjective and were created only to simplify the interpretation of the results for all drugs along the three dimensions of access. For the purposes of this report, we refer to tiers 4-6 as "tier 4" and assume that tier 4 is equivalent to a specialty tier. Some plans have no tiers (11 percent) or fewer than four tiers (7 percent)-for the latter, the specialty tier may actually be tier 3. Therefore, by collapsing tiers 4-6 and labeling this as a specialty tier, we may be misclassifying up to 28 percent of the plans. Likewise, cost-sharing for drugs placed in an injectible tier is also likely to be high since these drugs are quite expensive. For the purposes of our analyses, we assign drugs to the lowest tier on which they appear. We included only drugs approved prior to 2009 in order to provide adequate time for marketing and plan coverage decisions. Our list excludes drugs that are covered by Medicare Part A or B and blood products. We noted which drugs are available in generic form and which are biologics versus new chemical entities. Drugs are listed in chronological order of the date of approval of the first orphan indication relevant to the Medicare population (some drugs have multiple relevant orphan indications). Twenty-nine (29 percent) of the drugs are available in generic form and eleven (11 percent) are biologics. The 1,295 national plans represent 12 plan sponsor organizations, 26 unique contracts, and 88 unique formularies (a sponsor may use the same formulary for multiple plans). More than half (60 percent) of the plans have We performed a separate analysis of Medicare Part D coverage of orphan drugs with only a pediatric indication orphan approval. Benchmark plans and nonnational plans are more likely to have a deductible and to have a higher deductible than nonbenchmark and national plans. An additional 29 drugs (29 percent) are covered by at least 75 percent of the plans. As explained in the note for the table, a search of formularies conducted in late spring 2010 found a few plans had initiated coverage of Galzin and Renacidin Irrigation. On average, an orphan drug is covered by 83 percent (standard deviation: 26 percent) of benchmark plans and 85 percent (standard deviation: 24 percent) of non-benchmark plans. The benchmark plans have a higher percentage of drugs that fall within the novery low and low-coverage categories (11 percent in benchmark versus 6 percent in nonbenchmark plans). There is considerably more variation in coverage rates between national and nonnational plans, with national plans having higher coverage rates. On average, an orphan drug is covered by only 77 percent (standard deviation: 32 percent) of nonnational plans, compared to 86 percent (standard deviation: 24 percent) of national plans. Within nonnational plans, almost a quarter (23 percent) of the drugs are classified as having a novery low or low-coverage rate, compared to only 4 percent of drugs within national plans. Conversely, 19 of the 95 covered drugs are covered by less than 50 percent of the nonnational plans. For these analyses, and the utilization management analyses below, we excluded the four drugs not covered by any plan. Twenty-eight (29 percent) are placed on tier 4 by at least 75 percent of the plans. Table C-A2 shows coverage rate, tier placement, and utilization management rates by drug. See Tables C-A3 and C-A4 for a list of orphan drugs with only a pediatric orphan indication (N = 27) and the coverage rate, tier placement, and utilization management rates by drug. In terms of the percentage of plans that cover the drugs, Medicare prescription drug plan coverage of orphan drugs is relatively extensive. The fact that many of these drugs are in protected classes (for either the orphan indication or another approved indication) may explain the high coverage rates of these drugs. However, plan coverage alone does not guarantee access-tier placement and utilization management requirements may limit access of covered drugs by imposing financial barriers. However, we found minimal use of quantity limits or step therapy, the latter of which was expected since there are often few, if any, therapeutic substitutes for these orphan drugs. However, orphan diseases, by definition, have limited treatment options and there may not be a lower-cost therapy available to patients. The cost-related and utilization management-related nonadherence for orphan drugs among the Medicare population is not known. Drugs with multiple orphan designations, noted in this table, often have different dates associated with each approved indication.

Many patients progress slowly over several months or years to women's health center greenville nc purchase lady era with mastercard irreversible severe myocardial dysfunction and death; cardiac transplant may be the only option for survival pregnancy gas purchase generic lady era. Dilated cardiomyopathy this diffuse group of diseases pregnancy joint pain buy generic lady era 100mg, usually of unknown etiology, shows no evidence of myocardial inflammation. Most pediatric conditions in this category are clinically and pathologically indistinguishable with the following notable exceptions. In this condition, the left coronary artery arises from the pulmonary artery, whereas the right coronary artery arises normally from the aorta. As a result, the left ventricular myocardium is poorly perfused because of the low pulmonary artery pressure, so that ischemia and infarction occur. Subsequently, collaterals develop between the high-pressure right and the low-pressure left coronary arterial systems. In this situation, blood flows from the right into the left coronary arterial system. The left ventricular myocardium is poorly perfused because blood flows in a retrograde direction into the pulmonary artery. These episodes are short and are believed to represent transient myocardial ischemia. Other children may show no symptoms, but many of the patients develop signs and symptoms of congestive cardiac failure. No abnormal auscultatory findings may exist, or a soft, apical pansystolic murmur of mitral regurgitation may be found. In a few patients, it shows only left ventricular hypertrophy and strain or a pattern of complete left bundle branch block. Echocardiography shows nonspecific cardiac dilation and left ventricular dysfunction. Only the right coronary artery, which is enlarged, can be identified arising from the aorta. Using color Doppler, the origin of the anomalous coronary artery may be seen as a jet of flow from the left coronary artery into the pulmonary artery. Patients with cardiac failure should receive anticongestive therapy and should undergo cardiac catheterization. Surgical options include reimplantation of the left coronary artery to the aorta, or surgical creation of a tunnel within the pulmonary artery to establish continuity between the coronary artery and the aorta. Cardiac transplantation may be indicated in patients with severe irreversible left ventricular damage. Anthracycline chemotherapeutic agents, such as doxorubicin (Adriamycin), through unclear mechanisms possibly involving excessive oxygen radical formation, can cause a cardiomyopathy. Most chemotherapeutic protocols limit the cumulative dose of these agents to 400 mg/m2, because the incidence of cardiac dysfunction rises sharply with larger doses. A small number of patients, however, develop cardiac failure at levels below that considered the threshold for toxicity, suggesting that the toxic effect occurs at a low dose but only manifests clinically in certain patients. Patients may develop chronic congestive heart failure years after the conclusion of therapy. Various drugs are being investigated that may prevent cardiac injury during chemotherapy. The endocardium could be 2 mm thick, whereas in the normal individual it is only a few cells thick. Electrocardiograms showed left ventricular hypertrophy and inverted T waves in the left precordial leads. Gross cardiomegaly, particularly of the left atrium and left ventricle, was seen on chest X-ray. The echocardiogram showed a strikingly echogenic endocardium, left ventricular enlargement, decreased systolic function, and mitral regurgitation. It is caused by an incessant tachyarrhythmia, either ventricular or 274 Pediatric cardiology "supraventricular" (see Chapter 10). Following elimination of the tachyarrhythmia, normal cardiac function usually recovers, although some degree of left ventricular dilation may persist. The hypertrophy may be concentric, involving the ventricular walls diffusely, or asymmetric, unevenly affecting portions of the wall usually the ventricular septum. In contrast to dilated cardiomyopathy, the left ventricular cavity has a normal or decreased size. During systole, the hypertrophied myocardium bulges into the left ventricular outflow tract and may result in subaortic obstruction. Other names for this condition are hypertrophic obstructive cardiomyopathy and asymmetric septal hypertrophy. The disease may be caused by mutations of genes coding for various contractile proteins. This condition frequently occurs as an autosomal dominant or sex-linked condition (occurring in males). The natural history and prognosis are variable; sudden death is not uncommon, even in patients who have no important obstruction or sentinel arrhythmia. History Syncope may be present, but congestive cardiac failure is rare unless significant diastolic dysfunction is present. The family history may reveal other members with similar diagnosis or a history of sudden death. Physical examination the peripheral pulses are brisk, and palpation of the apex may reveal a double impulse. A long systolic ejection murmur is present along the left sternal border 9 the cardiac conditions acquired during childhood 275 and faintly radiates to the base. Chest X-ray Chest X-ray does not usually show cardiac enlargement related to the left ventricle and left atrium because hypertrophy alone may not alter the external silhouette. In contrast to other forms of aortic stenosis, the ascending aorta is usually of normal size. Echocardiogram the echocardiogram shows striking thickening of the left ventricular walls, particularly the interventricular septum, which may be 23 cm thick, compared with the normal 1 cm. This creates low pressure that "pulls" the valve leaflet towards the interventricular septum during systole. Color Doppler reveals disturbed flow within the left ventricular outflow tract, beginning proximal to the aortic valve. Spectral Doppler allows estimation of the systolic gradient by measurement of the maximum velocity; this may change from beat to beat because of the dynamic nature of the muscular obstruction. Management Because the subsequent therapies increase the gradient, the use of digoxin or other inotropes is contraindicated in these patients. Beta-blockers, calcium channel blockers, and other "negative inotropes" have been advocated for these patients but do not necessarily prevent sudden death. Surgical excision of portions of the septal myocardium (myomectomy) has been helpful in some patients with obstruction. Alcohol injected via a coronary artery catheter can achieve a form of nonsurgical myomectomy by selectively destroying obstructing myocardium.

Echocardiography is very helpful in identifying the diagnosis and showing the size of the communication menstruation nutrition order lady era master card. The hemodynamics are accessible by measuring the left ventricular dimensions womens health 15 minute workout app generic lady era 100 mg mastercard, which increase as the volume of pulmonary blood flow increases menstruation pronunciation generic lady era 100mg with visa. Communication at the atrial level the second hemodynamic principle governs shunts that occur at the atrial level. Most atrial communications leading to signs and symptoms are large, hence atrial 3 Classification and physiology of congenital heart disease in children 89 pressures are equal. Therefore, pressure differences cannot be the primary determinant of blood flow through the atrial communication. The direction and magnitude of blood flow through an atrial defect are determined by the relative compliances of the atria and the ventricles. In contrast to the shunts at the ventricular or great vessel level, which are influenced by the relative resistances of the pulmonary and systemic beds and therefore by systolic events, shunts at the atrial level are governed by factors that influence ventricular filling (diastolic events). At any given pressure, the more compliant the ventricle, the greater is the volume that it can receive. Ventricular compliance depends on the thickness of the ventricular wall and on factors, such as fibrosis, that alter the stiffness of the ventricle. Normally, the left ventricle is thicker walled and less compliant than the thinwalled right ventricle. This difference in compliance favors blood flow from the left atrium to the right atrium in patients with atrial communication. In addition, this direction of blood flow is favored because the valveless vena cavae add to the capacitance and compliance of the right atrium. The direction and volume of an atrial-level shunt can be altered by changes in the degree of thickness of the ventricular walls or by other factors, such as myocardial fibrosis. Right ventricular compliance increases during infancy as a result of the decrease in pulmonary vascular resistance. During fetal life, the right ventricle develops systemic levels of pressure and ejects a large portion of its output across the ductus arteriosus into the aorta. The right ventricle is thick walled and, at birth, weighs twice as much as the left ventricle. Since ventricular compliance is affected by the thickness of the ventricular wall, the right ventricle is relatively less compliant at birth. Following birth, the pulmonary vascular resistance decreases and the right ventricular systolic pressure falls to a normal level (25 mmHg). Consequently, the right ventricular wall thins and, by 1 month, the left ventricular weight exceeds that of the right ventricle. The thinning of the wall is associated with an increase in right ventricular compliance. Although this sequence occurs in every neonate, in those with an atrial septal defect, as right ventricular compliance increases, so does the volume of left-to-right shunt. Echocardiography, in addition to demonstrating the anatomic details of the malformation, shows features of the hemodynamics. The principal change is an increase in right ventricular size and displacement of the ventricular septum during diastole towards the left ventricle. Obstructions the third hemodynamic principle concerns cardiac conditions with obstruction to blood flow. In infants and children, the primary response to obstruction is hypertrophy, not dilation. Pressure increases in the chamber proximal to the obstruction, leading to hypertrophy of that chamber. Beyond the neonatal period, a normal level of pressure is usually maintained distal to the obstruction since the cardiac output is also usually maintained at a normal level. Many of the signs and symptoms of patients with obstruction are related to the pressure elevation proximal to the obstruction, not to low pressure distal to the obstruction. Hence the cardiac chamber, usually ventricle, is hypertrophied proportionally to the level of pressure elevation. Echocardiography is useful in measuring the gradient across the obstruction using the modified Bernoulli equation given earlier. In addition, the thickness of the ventricular wall proximal to the obstruction is proportional to the level of ventricular systolic pressure. Valvar regurgitation the fourth principle governs conditions with valvar regurgitation. In valvar insufficiency, the chamber on either side of the insufficient valve is enlarged and the volume of blood in each chamber is larger than normal because the chambers are handling not only the normal cardiac output but also the regurgitant volume. In contrast to conditions with obstruction, where the response is hypertrophy, the response to the increased volume is usually chamber enlargement. The major signs and symptoms in these patients are related to enlargement of 3 Classification and physiology of congenital heart disease in children 91 the cardiac chambers. The echocardiogram demonstrates the enlarged cardiac chambers of the valve involved. In addition, the velocity of the regurgitant jet can be measured to indicate the gradient across the valve. Pulmonary hypertension the term pulmonary hypertension indicates an elevation of pulmonary arterial pressure from whatever cause. Therefore, for any given level of pressure, various combinations of pressure and blood flow may be present. The echocardiogram is useful in determining the level of pulmonary artery pressure by measuring the trans-tricuspid valvar jet and the underlying cause by assessing cardiac chamber size. If chamber size is normal, this indicates that the volume of pulmonary blood flow is limited by the elevated pulmonary resistance or enlarged if the blood flow is increased. Increased pulmonary vascular resistance (R) the elevated resistance may occur at either of two sites in the pulmonary circulation: at a precapillary site (usually the pulmonary arterioles) or at a postcapillary site (such as the pulmonary veins, the left atrium, or the mitral valve). Pulmonary hypertension from increased pulmonary vascular resistance results from narrowing of the pulmonary arterioles. At birth, the pulmonary arterioles show a thick medial coat and a narrow lumen, so the pulmonary resistance is elevated. With time, the media of the arteriole thins, the lumen widens, and the pulmonary resistance falls. The arterioles of neonates and young infants are responsive to various influences, such as oxygen and acidosis, so that with hypoxia they contract further and with administration of oxygen they dilate. Such responsiveness remains longer in infants with cardiac malformations associated with increased pulmonary blood flow and elevated pressures. Pulmonary resistance may also be elevated because of acquired lesions in the pulmonary arterioles. These changes develop at a variable rate and influence the clinical findings, the operative results, and mortality of patients. If pulmonary vascular resistance is fixed or poorly reactive to maneuvers that usually produce relaxation of pulmonary arterioles, such as hyperventilation or high concentrations of inspired oxygen, the operative risk is high, and the pulmonary resistance remains elevated following operation.

What appears here directly as dissociation is in reality only one of the elementary forms of socialization menstruation sync proven lady era 100mg. This reserve with its overtone of concealed aversion appears once more womens health alliance cary ob gyn buy lady era on line amex, however breast cancer wallpaper buy generic lady era 100mg on line, as the form or the wrappings of a much more general psychic trait of the metropolis. It assures the individual of a type and degree of personal freedom to which there is no analogy in other circumstances. It has its roots in one of the great developmental tendencies of social life as a whole; in one of the few for which an approximately exhaustive formula can be discovered. The most elementary stage of social organization which is to be found historically, as well as in the present, is this: a relatively small circle almost entirely closed against neighbouring foreign or otherwise antagonistic groups but which has however within itself such a narrow cohesion that the individual member has only a very slight area for the development of his own qualities and for free activity for which he himself is responsible. Political and familial groups began in this way as do political and religious communities; the self-preservation of very young associations requires a rigorous setting of boundaries and a centripetal unity and for that reason it cannot give room to freedom and the peculiarities of inner and external development of the individual. From this stage social evolution proceeds simultaneously in two divergent but none the less corresponding directions. In the measure that the group grows numerically, spatially, and in the meaningful content of life, its immediate inner unity and the definiteness of its original demarcation against others are weakened and rendered mild by reciprocal interactions and interconnections. And at the same time the individual gains a freedom of movement far beyond the first jealous delimitation, and gains also a peculiarity and individuality to which the division of labour in groups, which have become larger, gives both occasion and necessity. However much the particular conditions and forces of the individual situation might modify the general scheme, the state and Christianity, guilds and political parties and innumerable other groups have developed in accord with this formula. This tendency seems to me, however, to be quite clearly recognizable also in the development of individuality within the framework of city life. Small town life in antiquity as well as in the Middle Ages imposed such limits upon the movements of the individual in his relationships with the outside world and on his inner independence and differentiation that the modern person could not even breathe under such conditions. Even today the city dweller who is placed in a small town feels a type of narrowness which is very similar. The smaller the circle which forms our environment and the more limited the relationships which have the possibility of transcending the boundaries, the more anxiously the narrow community watches over the deeds, the conduct of life and the attitudes of the individual and the more will a quantitative and qualitative individuality tend to pass beyond the boundaries of such a community. The incessant threat against its existence by enemies from near and far brought about that stern cohesion in political and military matters, that supervision of the citizen by other citizens, and that jealousy of the whole toward the individual whose own private life was repressed to such an extent that he could compensate himself only by acting as a despot in his own household. The tremendous agitation and excitement, and the unique Georg Simmel 73 colourfulness of Athenian life is perhaps explained by the fact that a people of incomparably individualized personalities were in constant struggle against the incessant inner and external oppression of a de-individualizing small town. This created an atmosphere of tension in which the weaker were held down and the stronger were impelled to the most passionate type of self-protection. For the correlation, the factual as well as the historical validity of which we are here maintaining, is that the broadest and the most general contents and forms of life are intimately bound up with the most individual ones. Both have a common prehistory and also common enemies in the narrow formations and groupings, whose striving for self-preservation set them in conflict with the broad and general on the outside, as well as the freely mobile and individual on the inside. The mutual reserve and indifference, and the intellectual conditions of life in large social units are never more sharply appreciated in their significance for the independence of the individual than in the dense crowds of the metropolis, because the bodily closeness and lack of space make intellectual distance really perceivable for the first time. It is obviously only the obverse of this freedom that, under certain circumstances, one never feels as lonely and as deserted as in this metropolitan crush of persons. For here, as elsewhere, it is by no means necessary that the freedom of man reflect itself in his emotional life only as a pleasant experience. It is not only the immediate size of the area and population which, on the basis of world-historical correlation between the increase in the size of the social unit and the degree of personal inner and outer freedom, makes the metropolis the locus of this condition. It is rather in transcending this purely tangible extensiveness that the metropolis also becomes the seat of cosmopolitanism. In the same way, economic, personal and intellectual relations in the city (which are its ideal reflection) grow in a geometrical progression as soon as, for the first time, a certain limit has been passed. Every dynamic extension becomes a preparation not only for a similar extension but rather for a larger one, and from every thread which is spun out of it there continue, growing as out of themselves, an endless number of others. For the metropolis it is decisive that its inner life is extended in a wave-like motion over a broader national or international area. Weimar was no exception because its significance was dependent upon individual personalities and died with them, whereas the metropolis is characterized by its essential independence even of the most significant individual personalities; this is rather its antithesis and it is the price of independence which the individual living in it Rethinking Architecture 74 enjoys. The most significant aspect of the metropolis lies in this functional magnitude beyond its actual physical boundaries and this effectiveness reacts upon the latter and gives to it life, weight, importance and responsibility. A person does not end with the limits of his physical body or with the area to which his physical activity is immediately confined but embraces, rather, the totality of meaningful effects which emanates from him temporally and spatially. In the same way the city exists only in the totality of the effects which transcend their immediate sphere. This is already expressed in the fact that individual freedom, which is the logical historical complement of such extension, is not only to be understood in the negative sense as mere freedom of movement and emancipation from prejudices and philistinism. Its essential characteristic is rather to be found in the fact that the particularity and incomparability which ultimately every person possesses in some way is actually expressed, giving form to life. That we follow the laws of our inner nature-and this is what freedom is-becomes perceptible and convincing to us and to others only when the expressions of this nature distinguish themselves from others; it is our irreplaceability by others which shows that our mode of existence is not imposed upon us from the outside. They produce such extreme phenomena as the lucrative vocation of the quatorzieme in Paris. These are persons who may be recognized by shields on their houses and who hold themselves ready at the dinner hour in appropriate costumes so they can he called upon on short notice in case thirteen persons find themselves at the table. Exactly in the measure of its extension, the city offers to an increasing degree the determining conditions for the division of labour. It is a unit which, because of its large size, is receptive to a highly diversified plurality of achievements while at the same time the agglomeration of individuals and their struggle for the customer forces the individual to a type of specialized accomplishment in which he cannot be so easily exterminated by the other. The decisive fact here is that in the life of a city, struggle with nature for the means of life is transformed into a conflict with human beings, and the gain which is fought for is granted, not by nature, but by man. For here we find not only the previously mentioned source of specialization but rather the deeper one in which the seller must seek to produce in the person to whom he wishes to sell ever new and unique needs. All this leads to the narrower type of intellectual individuation of mental qualities to which the city gives rise in proportion to its size. Where quantitative increase of value and energy has reached its limits, one seizes on qualitative distinctions, so that, through taking advantage of the existing sensitivity to differences, the attention of the social world can, in some way, be won for oneself. For many types of persons these are still the only means of saving for oneself, through the attention gained from others, some sort of self-esteem and the sense of filling a position. In the same sense there operates an apparently insignificant factor which in its effects however is perceptibly cumulative, namely, the brevity and rarity of meetings which are allotted to each individual as compared with social intercourse in a small city. This appears to me to be the most profound cause of the fact that the metropolis places emphasis on striving for the most individual forms of personal existence-regardless of whether it is always correct or always successful. The development of modern culture is characterized by the predominance of what one can call the objective spirit over the subjective; that is, in language as well as in law, in the technique of production as well as in art, in science as well as in the objects of domestic environment, there is embodied a sort of spirit (Geist), the daily growth of which is followed only imperfectly and with an even greater lag by the intellectual development of the individual. If we survey, for instance, the vast culture which during the last century has been embodied in things and in knowledge, in institutions and in comforts, and if we compare them with the cultural progress of the individual during the same period-at least in the upper classes-we would see a frightful difference in rate of growth between the two which represents, in many points, rather a regression of the culture of the individual with reference to spirituality, delicacy and idealism. This discrepancy is in essence the result of the success of the growing division of labour. For it is this which requires from the individual an ever more one-sided type of achievement which, at its highest point, often permits his personality as a whole to fall into neglect.

Regardless of whether the resistance to menstruation in africa cheap lady era 100mg online pulmonary blood flow resides in the infundibulum or the pulmonary arterioles womens health ri discount lady era 100 mg, the hemodynamic effects are similar; but the prognosis is different menopause kidneys order lady era online pills. The exact incidence of spontaneous closure is unknown, but up to 5% of large ventricular septal defects and at least 75% of small defects undergo spontaneous closure; others become smaller. The perimembranous defect may become smaller by the septal tricuspid valve leaflet creating a mobile and partially restrictive so-called aneurysm of the membranous septum. Most instances of spontaneous closure occur by 3 years of age, but may close in adolescents or even adulthood when the pulmonary vascular resistance is still near normal levels. As the closure of the ventricular septal defect occurs, the systolic murmur softens, and of the secondary features that reflect pulmonary arterial pressure (Figure 4. Those features that reflect increased pulmonary blood flow also gradually disappear. Thus, eventually, the systolic murmur disappears and no residual cardiac abnormalities exist, although the heart may remain large for some months. Some liken the gradual resolution of cardiomegaly to the process of a patient "growing into" their own heart size, rather than calling it an active reduction in heart size. Echocardiogram A large ventricular septal defect appears as an area of "dropout" within the septum by cross-sectional two-dimensional (2D) echocardiography. Perimembranous infracristal defects appear near the tricuspid valve septal leaflet and the right aortic valve cusp. Small defects, especially those within the trabecular (muscular) septum, may not be apparent by 2D, but color Doppler demonstrates a multicolored jet traversing the septum, representing the turbulent shunt from left to right ventricle. The maximum velocity of the blood traversing the defect, determined by spectral Doppler, is used to estimate the interventricular pressure difference. Large defects that lead to high right ventricular systolic pressure are reflected as low-velocity flow across the defect. In a small defect with normal right ventricular systolic pressure, the shunt is of high velocity, reflecting the large interventricular pressure difference. Small ventricular septal defects in neonates may have low-velocity flow, indicating that pulmonary resistance and right ventricular pressure have not yet fallen. Low-velocity shunt, or right-to-left shunt, is seen in older patients with pulmonary vascular obstructive disease or right ventricular outflow obstruction. In patients with a large ventricular septal defect, 2D echocardiography reveals left atrial and left ventricular enlargement. Left ventricular systolic function may appear hyperdynamic because of the increased stroke volume associated with a large ventricular septal defect. The pulmonary systolic pressure can be determined by analysis of the Doppler signal that regurgitates through the tricuspid valve. The purposes of the procedure are to define the hemodynamics, to identify coexistent cardiac anomalies, and to localize the site(s) of the ventricular septal defect(s). The pulmonary arterial and right ventricular systolic pressures are identical with those in the aorta and the left ventricle. If the pulmonary vascular resistance is increased, the increase in oxygen saturation at the right ventricular level is not as large as when it is lower. Left ventriculography is indicated to locate the position of the ventricular septal defect(s) because location influences operative repair. Aortography may also be performed to exclude a coexistent patent ductus arteriosus, which can be a silent partner to the ventricular septal defect. Operative considerations Patients with a large ventricular septal defect and congestive cardiac failure should be treated with diuretics, inotropes, and/or afterload reduction and with aggressive nutritional support (discussed in Chapter 11). Fluid restriction (which also means caloric restriction) is usually counterproductive. Although these measures improve the clinical status, many patients frequently show persistent findings of cardiac failure, indicating a need for operative treatment. Corrective operation for closure of the ventricular septal defect is indicated in infancy for patients with persistent cardiac failure and pulmonary hypertension. Cardiopulmonary bypass is instituted, the right atrium is opened, and, by working through the tricuspid valve, the ventricular septal defect is closed using a patch of Dacron or pericardium. The long-term results of the procedure are excellent; virtually no patients who had normal or reactive pulmonary vascular resistance preoperatively develop late pulmonary vascular obstructive disease. Banding of the pulmonary artery is a palliative procedure that causes an increase in the resistance to blood flow into the 114 Pediatric cardiology lungs. Therefore, the pulmonary artery pressure and volume of blood flow returning to the left side of the heart are reduced, improving congestive cardiac failure. Because the risk for operative ventricular septal defect closure is low (usually less than that for banding and subsequent reoperation for debanding with defect closure), corrective surgery is preferable. Small or medium ventricular septal defects the size of ventricular septal defects varies considerably. The previous section discussed those defects whose diameter approached the size of the aortic annulus. The direction and magnitude of blood flow in a small- or medium-sized ventricular septal defect depend on the size of the defect and the relative resistances of the systemic and pulmonary vascular beds. The pulmonary arterial pressures are lower than the systemic pressures because the defect limits the transmission of left ventricular systolic pressure to the right side of the heart. Pulmonary vascular disease may occur; but appears at a slower rate than with a large defect and only in the few patients who have a large volume of left-to-right shunt despite the pressure-restrictive defect. In general, the volume of pulmonary blood flow varies with the size of the defect and the level of pulmonary vascular resistance. Since beyond infancy most children have normal pulmonary vascular resistance, the shunt is directly related to the size of the defect. In some patients, the defect is so small that the shunt is undetectable by oximetry data, whereas in patients with a larger defect, the pulmonary blood flow is three times the systemic blood flow. History Most of the patients in this category have a small defect which shows little increase in pulmonary blood flow and none in pulmonary artery pressure. Most patients 4 Anomalies with a left-to-right shunt in children 115 with a small- or medium-sized ventricular septal defect are asymptomatic. Heart disease is usually detected by the discovery of a murmur either before discharge from the newborn nursery or, more commonly, at the first postnatal visit. The occasional patient with large pulmonary blood flow may have frequent respiratory infections and pneumonia. Physical examination Usually no evidence of cardiomegaly is found on physical examination. Some murmurs are pansystolic, loud (grades 3/64/6), may be accompanied by a thrill, and are heard along the left sternal border. The "squirty" quality of the murmur is probably due to constantly changing pitch as the blood accelerates through the narrowing defect.

A good study of peasant architecture in Europe menstruation 6 weeks after giving birth buy discount lady era 100mg online, for example breast cancer 990 new balance lady era 100mg with amex, would show the utter vanity of wanting to women's health clinic oregon city order lady era with a mastercard return to the little individual house Rethinking Architecture 354 with its thatched roof. History protects us from historicism-from a historicism that calls on the past to resolve the questions of the present. But what is interesting is that in imperial Rome there were, in fact, brothels, pleasure quarters, criminal areas, etc. The baths were a very important place of pleasure and encounter, which slowly disappeared in Europe. In the Middle Ages, the baths were still a place of encounter between men and women as well as of men with men and women with women, although that is rarely talked about. What were referred to and condemned, as well as practised, were the encounters between men and women, which disappeared over the course of the sixteenth and seventeenth centuries. One of the characters, Lacenaire, was-no one mentions it-a swine and a pimp who used young boys to attract older men and then blackmailed them; there is a scene that refers to this. It required all the naivetй and anti-homosexuality of the Surrealists to overlook that fact. The bath was a sort of cathedral of pleasure at the heart of the city, where people could go as often as they want, where they walked about, picked each other up, met each other, took their pleasure, ate, drank, discussed. Sexuality was obviously considered a social pleasure for the Greeks and the Romans. What is interesting about male homosexuality today-this has apparently been the case of female homosexuals for some time-is that their sexual relations are immediately translated into social relations and the social relations are understood as sexual relations. For the Greeks and the Romans, in a different fashion, sexual relations were located within social relations in the widest sense of the term. There is, in fact, a very interesting form of sociality that was studied by Alain Corbin in Les Filles de noces. There was a sociality of the brothel, but the sociality of the baths as it existed among the ancients-a new version of which could perhaps exist again-was completely different from the sociality of the brothel. What about confessional architecture-the kind of architecture that would be associated with a confessional technology? There one finds precise regulations concerning life in common; affecting sleeping, eating, prayer, the place of each individual in all of that, the cells. Space is fundamental in any form of communal life; space is fundamental in any exercise of power. The architects worked on this, and at the end of the study someone spoke up-a Sartrean psychologist-who firebombed me, saying that space is reactionary and capitalist, but history and becoming are revolutionary. Today everyone would be convulsed with laughter at such a pronouncement, but not then. Your approach is perhaps more concerned with space, rather than architecture, in that the physical walls are only one aspect of the institution. How would you characterize the difference between these two approaches, between the building itself and space? It is true that for me, architecture, in the very vague analyses of it that I have been able to conduct, is only taken as an element of support, to ensure a certain allocation of people in space, a canalization of their circulation, as well as the coding of their reciprocal relations. So it is not only considered as an element in space, but is especially thought of as a plunge into a field of social relations in which it brings about some specific effects. For example, I know that there is a historian who is carrying out some interesting studies of the archaeology of the Middle Ages, in which he takes up the problem of architecture, of houses in the Middle Ages, in terms of the problem of the chimney. I think that he is in the process of showing that beginning at a certain moment it was possible to build a chimney inside the house-a chimney with a hearth, not simply an open room or a chimney outside the house; that at that moment all sorts of things changed and relations between individuals became possible. All of this seems very interesting to me, but the conclusion that he presented in an article was that the history of ideas and thoughts is useless. So often in the history of techniques it takes years or even centuries to implement them. It is certain, and of capital importance, that this technique was a formative influence on new human relations, but it is impossible to think that it would have been developed and adapted had there not been in the play and strategy of human relations something which tended in that direction. What is interesting is always interconnection, not the primacy of this over that, which never has any meaning. What is the relationship between these spatial metaphors describing disciplines and more concrete descriptions of institutional spaces? What is striking in the epistemological mutations and transformations of the seventeenth century is to see how the spatialization of knowledge was one of the factors in the constitution of this knowledge as a science. If the natural history and the classifications of Linneaus were possible, it is for a certain number of reasons: on the one hand, there was literally a spatialization of the very object of their analyses, since they gave themselves the rule of studying and classifying a plant only on the basis of that which was visible. All the traditional elements of knowledge, such as the medical functions of the plant, fell away. Subsequently, it was spatialized insofar as the principles of classification had to be found in the very structure of the plant: the number of elements, how they were arranged, their size, etc. Then there was the spatialization into illustrations within books, which was only possible with certain printing techniques. Then the spatialization of the reproduction of the plants themselves, which was represented in books. There is the model of the military camp, where the military hierarchy is to be read in the ground itself, by the place occupied by the tents and the buildings reserved for each rank. It reproduces precisely through architecture a pyramid of power; but this is an exceptional example, as is everything military-privileged in society and of an extreme simplicity. Fortunately for human imagination, things are a little more complicated than that. The savoir of architecture is partly the history of the profession, partly the evolution of a science of construction, and partly a rewriting of aesthetic theories. I am not even sure if it is worth constantly asking the question of whether government can be the object of an Michel Foucault 357 exact science. On the other hand, if architecture, like the practice of government and the practice of other forms of social organization, is considered as a techne, possibly using elements of sciences like physics, for example, or statistics, etc. But if one wanted to do a history of architecture, I think that it should be much more along the lines of that general history of the techne, rather than the histories of either the exact sciences or the inexact ones. Whereas government is also a function of technology: the government of individuals, the government of souls, the government of the self by the self, the government of families, the government of children, and so on. I believe that if one placed the history of architecture back in this general history of techne, in this wide sense of the word, one would have a more interesting guiding concept than by considering opposition between the exact sciences and the inexact ones. This has an obvious consequence for a discipline such as architecture which has exerted its influence through materiality. Symbolically- but also practically-the city is no longer governed by physical boundaries but by systems of electronic surveillance. Within the home too the traditional physical window gives way to the interface of the screen. Virilio could be criticized for the utopianism of his futuristic vision, and for failing to take sufficient account of the corporeality of the body in his thinking. Likewise it could be argued that the homogenization of global communications, far from promoting a simple placelessness, may have a counter-effect of a renewed celebration of the specificity of material place.

The commercially available solution is a mixture of 15 amino acids in a concentration of 1 menopause itching purchase lady era 100 mg with mastercard. The solution also contains standard concentrations of sodium pregnancy exercise order 100 mg lady era, calcium menopause 30 symptoms order 100 mg lady era mastercard, magnesium, chloride, and lactate. The amino acids act as the osmotic agent and are absorbed across the peritoneal membrane during the dwell to a variable extent. The evidence to support improvement in nutrition, as well as overall outcomes, is not compelling, but this dialysate can be used in malnourished patients both for nutritional supplementation and reduction of glucose exposure. Used in combination with icodextrin, it has the potential to preserve peritoneal membrane integrity while reducing excessive glucose absorption. A 2 L bag contains approximately 25% of the daily protein requirement of a 70 kg adult. Successful utilization of the amino acids is dependent on an adequate calorie load, and amino acid dialysate (Nutrineal) should be instilled after the patient has had a meal. Amino acidbased dialysate should be avoided in severe uremia, disorders of amino acid metabolism, severe liver disease, acidosis, hypokalemia, and hypersensitivity. The catheter can be inserted surgically under direct vision through a minilaparotomy, percutaneously using the Seldinger technique, or with peritoneoscopic or laparoscopic guidance. There are numerous catheter designs, such as the Swan neck catheter (said to undergo less catheter tip migration and have fewer exit-site infections) and curled catheters. None offers a significant proven advantage over the original double-cuffed Silastic Tenckhoff catheter, and this original and simple design remains the most commonly used catheter. The intraabdominal portion of the catheter has multiple perforations through which dialysate flows. With the deep cuff placed in a paramedian position in the rectus muscle, the extraperitoneal portion of the catheter is tunneled through the subcutaneous tissue to exit the skin, pointing laterally and caudally. The superficial cuff is located inside the subcutaneous tunnel, 2 to 3 cm from the exit site. Peritoneal dialysis can be initiated immediately after catheter placement if it is urgently required, provided that exchange volumes are small and the patient is kept recumbent. In practice, dialysis typically has been deferred for approximately 4 weeks after insertion to allow the surgical wound and exit site to heal properly. Some providers will use hemodialysis as a temporary measure if necessary until peritoneal dialysis is initiated, whereas a minority will initiate urgent start peritoneal dialysis, using low volumes in the supine position. A prescription entails modifications of the variable components to arrive at a regimen that provides for adequate solute and fluid removal to meet clinical needs while maintaining reasonable quality of life. Dialysis adequacy regarding solute removal, fluid status, nutritional status, and clinical well-being are monitored regularly (see later discussion), and the prescription is modified accordingly. The overall clearance capacity of the peritoneum for small solutes is limited by the volume of dialysate that can be provided daily. Initially, most patients have residual kidney function that contributes to the total solute clearance. As kidney function is gradually lost, patients require either larger exchange volumes (2. Creatinine clearance (CrCl) is provided by both peritoneal clearance and residual kidney function. Although the validity of these measurements and calculations continues to cause some controversy, they have become the accepted methods of estimating dialysis adequacy, and various national and international organizations have set minimum targets for both CrCl and urea clearance based on them. However, it is sometimes difficult for patients to achieve one or both targets, and doubt remains about the precise level at which the targets should be set. Several guidelines have since emerged including the United Kingdom Renal Association Guidelines, the European Renal Best Practice, and the International Society for Peritoneal Dialysis Guidelines, all with similar recommendations. In contrast, the uremic patient is anorectic with dysgeusia, nausea, and complaints of fatigue. In addition to these clinical parameters, two biochemical measures are used to assess adequacy of solute removal: 1. An index of peritoneal urea removal, expressed as Kt/V, is urea clearance (K) multiplied by time (t) and related to total body water volume, which is assumed to be the urea distribution volume (V). Kt is obtained by multiplying the ratio of effluent dialysate to plasma urea nitrogen concentration (D/Purea) by the 24-hour effluent drain volume. Kidney urea clearance is added to this value to yield the total daily body clearance. However, it is more accurate to use the formula of Watson and Watson, which takes into account weight (in kilograms), height (in centimeters), sex, and age (in years). However, the urinary component of CrCl is usually corrected for creatinine secretion by averaging it with the urinary urea clearance. The peritoneal CrCl is simply calculated by dividing the creatinine content of the 24-hr dialysate by the serum creatinine concentration. Although current targets may indicate the minimum solute clearance targets required to achieve an acceptable long-term clinical outcome, some patients need more dialysis to prevent uremic symptoms. In addition, it must always be remembered that the term dialysis adequacy is restricted to the description of solute removal adequacy only and does not encompass the other aspects of care. Control of hypertension, maintenance of fluid balance, maximal cardiovascular risk reduction, and management of comorbidities can hugely influence outcome in any dialysis patient, but, even here, conclusive, randomized, prospective studies are lacking. It is now well recognized that residual kidney function is extremely important in providing adequate solute and fluid clearance. Most studies show that residual kidney function correlates with improved morbidity and mortality, and its preservation forms an important part of the management for a peritoneal dialysis patient. To preserve residual kidney function, nephrotoxic drugs such as aminoglycosides and nonsteroidal antiinflammatory agents should be avoided whenever possible, and episodes of hypotension from any cause should be corrected as rapidly as possible. Residual kidney function is better preserved in patients receiving peritoneal dialysis than in those receiving hemodialysis, so peritoneal dialysis may be the better initial therapy option for end-stage kidney failure. This reflects the fact that the "dry weight" is difficult to achieve with precision. Whether this state of continuous mild overload is more or less harmful than the thrice-weekly rapid variation in fluid status experienced by a hemodialysis patient is unknown, but the problem tends to become more troublesome in the long term when residual kidney function is lost and peritoneal dialysis ultrafiltration capacity is reduced. It appears that fluid removal has a more significant impact on outcome than solute clearance. Net ultrafiltration of at least 750 mL/day is associated with better survival in anuric patients, although the exact reason is unclear. The use of icodextrin for the longest dwell achieves better fluid balance and results in improvement in left ventricular indices. This condition is in part due to losses of amino acids and approximately 8 to 12 grams of protein each day in the dialysate; additionally, peritonitis markedly increases dialysate protein losses. Patient appetite may be suppressed by absorbed dialysate glucose, uremia, and a sense of abdominal fullness, resulting in lower dietary intake. Both the Kt/V and the weekly CrCl correlate, albeit weakly, with dietary protein intake, suggesting that a certain minimum dose of dialysis is required for adequate protein intake. The serum albumin level is inversely related to both mortality and hospitalization in peritoneal dialysis patients, although it must be remembered that serum albumin is greatly influenced by inflammation and is a poor marker of nutritional status when used alone.

Area of high T1 signal within this heterogenous lesion is suggestive of subacute hemorrhage menopause when does it start order lady era overnight. Gradient-recalled echo or susceptibility-weighted imaging sequences emphasize magnetic susceptibility women's health big book of abs 4-week exercise plan buy cheap lady era 100 mg online, a characteristic causing a "blooming" T2* hypointensity (similar to womens health yoga poses buy lady era without prescription T2) that may indicate microhemorrhages, calcifications, amyloid deposition, hemorrhagic metastases, or cavernomas (Figure 35. Post-gadolinium (contrast) multiplanar or 3-dimensional volume T1-weighted images are a T1 sequence obtained before and after gadolinium administration that can demonstrate abnormal enhancement, which indicates breakdown of the blood-brain barrier. In regions containing higher fat content such as the orbits or cavernous sinuses, fat-saturation techniques greatly aid the detection of enhancement. Some institutions use post-gadolinium fluid-attenuation inversion-recovery sequences, which appear especially useful for discerning meningeal processes. Time-of-flight imaging is direction-dependent; thus, if a vertebral artery appears absent on the time-of-flight image but present on the gadolinium bolus image, retrograde flow in this vessel is implied, most likely from a subclavian steal phenomenon. These images are not trustworthy for measuring luminal diameter because this measurement varies contingent on the chosen display thresholds; thus, the source images offer the most accurate representation of true vessel caliber. In this patient with amyloid angiopathy, reduced signal may reflect subtle areas of hemosiderin (arrow) or calcium (arrowhead). This blood oxygen leveldependent response can be measured and used as a surrogate to image cerebral activity or function. As blood flow increases to more metabolically active areas in the brain, the ratio of oxyhemoglobin in those areas increases, resulting in a measurable difference (increase) in T2*. Gradient-recalled echo differentiates disk (gray) from bone (black), but it may overestimate neuroforaminal narrowing compared with conventional fast-spin echo T2. Sagittal images provide excellent coverage of the spinal canal, but axial images are the most helpful for discerning whether a process is intradural or extradural. Enhancement in primary brain tumors correlates with a higher histologic grade, but this relationship does not hold true for spine tumors. In patients who previously have had lumbar spine surgery, use of gadolinium can be useful for differentiating postoperative granulation tissue from disk material because granulation tissue enhances but disk material enhances minimally and only peripherally. The differential diagnosis of spine lesions on the basis of location is summarized in Box 35. Subacute hemorrhage becomes more isodense, and chronic blood products are hypodense. Epidural hematomas do not cross suture lines unless there is an associated fracture, but they can cross the midline. Acute subarachnoid hemorrhage from a ruptured aneurysm typically fills the suprasellar and sylvian cisterns, but the imaging pattern is not predictive of the aneurysmal location. Acute venous sinus thromboses typically have Hounsfield units of 70 or more if measured in the first 1 to 2 days. Vascular calcifications and the associated artifact often preclude accurate estimation of luminal narrowing. In acute stroke, the abnormal relative cerebral blood volume represents the infarct core, and the other parametric maps represent infarct core plus penumbra. Mismatch between the relative cerebral blood volume and relative cerebral blood flow indicates that there may be salvageable brain tissue (Figure 35. The temporal evolution of cerebral infarction on computed tomography can produce a fogging effect about 11 days after an infarct that transiently makes the previously hypodense infarct much less apparent. This feature is more reliable diagnostically than relying on the lenticular shape that can be seen with other types of hematomas. Subdural hematomas do cross suture lines and may appear acute, subacute, or chronic. Doppler imaging relies on the shifting frequencies of returning echoes that reflect off moving objects, in this case red blood cells. Doppler ultrasonography detects the presence, direction, and velocity of blood flow, which can then be used to estimate the caliber of vessel, although tortuosity of vessels or overlying calcifications that absorb sound waves confound this measurement. Typical patterns of decreased metabolism suggest the clinical diagnosis, such as Alzheimer disease (temporoparietal), frontotemporal dementia (frontotemporal), or Lewy body dementia (temporoparietal and occipital). This situation, in which flow is impaired but volume remains normal, suggests a penumbra that potentially could be salvaged with reperfusion of this segment. A 56-year-old man with a history of chronic hepatitis C is admitted to the hospital for confusion. Results of an infectious evaluation, including blood cultures, chest radiography, and urinalysis, are normal. Which of the following best describes the relationship of diffusion restriction and enhancement after an infarction? Diffusion restriction begins immediately after an infarction and correlates with gadolinium enhancement temporally b. Diffusion restriction begins immediately after an infarction and lasts for several days c. Diffusion restriction begins immediately and begins to fade as gadolinium enhancement starts to develop d. Diffusion restriction begins after 2 to 3 days and starts to fade as gadolinium enhancement starts to develop. Which of the following would not be expected to "bloom" with hypointensity on gradient recalled or susceptibility-weighted images? Processes causing marked cerebral edema can mimic subarachnoid hemorrhage by causing the basal cisterns to appear relatively hyperdense c. Gadolinium enhancement often correlates with high-grade brain tumors, but this relationship is less reliable in spinal malignancies. The peroneal and tibial motor conduction velocities are 22 m/s and 24 m/s, respectively. A patient presents with numbness and tingling of the right fourth and fifth fingers. All of the following electromyographic findings would fit with the diagnosis except: a. A prolonged N22 to N30 interpeak latency indicates peripheral nerve slowing, a cold limb with slow peripheral conduction, or a long limb (tall patient) b. Poorly defined N8, N22, N30, and P38 responses are most suggestive of diffuse disease of both the peripheral and the central proprioceptive pathways d. A normal N8 response, absent N22 and N30 responses, and prolonged P38 absolute latency indicate central slowing of the proprioceptive pathways in the thoracic or cervical cord. Preserved bilateral median N20 scalp responses are a positive prognostic indicator of an expected good clinical outcome b. If the median N20 scalp response is initially present in anoxic coma, there is little use to repeating the study in a few days if the patient remains comatose d.

To try out pedagogical experiments-and in particular to take up once again the well-debated problem of secluded education, by using orphans. The Panopticon is a privileged place for experiments on men, and for analysing with complete certainty the transformations that may be obtained from them. In this central tower, the director may spy on all the employees that he has under his orders: nurses, doctors, foremen, teachers, warders; he will be able to judge them continuously, alter their behaviour, impose upon them the methods he thinks best; and it will even be possible to observe the director himself. An inspector arriving unexpectedly at the centre of the Panopticon will be able to judge at a glance, without anything being concealed from him, how the entire establishment is functioning. The incompetent physician who has allowed contagion to spread, the incompetent prison governor or workshop manager will be the first victims of an epidemic or a revolt. The plague-stricken town, the panoptic establishment-the differences are important. They mark, at a distance of a century and a half, the transformations of the disciplinary programme. In the first case, there is an exceptional situation: against an extraordinary evil, power is mobilized; it makes itself everywhere present and visible; it invents new mechanisms; it separates, it immobilizes, it partitions; it constructs for a time what is both a counter-city and the perfect society; it imposes an ideal functioning, but one that is reduced, in the final analysis, like the evil that it combats, to a simple dualism of life and death: that which moves brings death, and one kills that which moves. The Panopticon, on the other hand, must be understood as a generalizable model of functioning; a way of defining power relations in terms of the everyday life of men. The fact that it should have given rise, even in our own time, to so many variations, projected or realized, is evidence of the imaginary intensity that it has possessed for almost two hundred years. But the Panopticon must not be understood as a dream building: it is the diagram of a mechanism of power reduced to its ideal form; its functioning, abstracted from any obstacle, resistance or friction, must be represented as a pure architectural and optical system: it is in fact a figure of political technology that may and must be detached from any specific use. It is polyvalent in its applications; it serves to reform prisoners, but also to treat patients, to instruct schoolchildren, to confine the insane, to supervise workers, to put beggars and idlers to work. It is a type of location of bodies in space, of distribution of individuals in relation to one another, of hierarchical organization, of disposition of centres and channels of power, of definition of the instruments and modes of intervention of power, which can be implemented in hospitals, workshops, schools, prisons. Whenever one is dealing with a multiplicity of individuals on whom a task or a particular form of behaviour must be imposed, the panoptic schema may be used. In each of its applications, it makes it possible to perfect the exercise of power. It does this in several ways: because it can reduce the number of those who exercise it, while increasing the number of those on whom it is exercised. Because it is possible to intervene at any moment and because the constant pressure acts even before the offences, mistakes or crimes have been committed. Because, in these conditions, its strength is that it never intervenes, it is exercised spontaneously and without noise, it constitutes a mechanism whose effects follow from one another. The panoptic schema makes any apparatus of power more intense: it assures its economy (in material, in personnel, in time); it assures its efficacity by its preventative character, its continuous functioning and its automatic mechanisms. In short, it arranges things in such a way that the exercise of power is not added on from the outside, like a rigid, heavy constraint, to the functions it invests, but is so subtly present in them as to increase their efficiency by itself increasing its own points of contact. The panoptic mechanism is not simply a hinge, a point of exchange between a mechanism of power and a function; it is a way of making power relations function in a function, and of making a function function through these power relations. In fact, any panoptic institution, even if it is as rigorously closed as a penitentiary, may without difficulty be subjected to such irregular and constant inspections: and not only by the appointed inspectors, but also by the public; any member of society will have the right to come and see with his own eyes how the schools, hospitals, factories, prisons function. The seeing machine was once a sort of dark room into which individuals spied; it has become a transparent building in which the exercise of power may be supervised by society as a whole. The panoptic schema, without disappearing as such or losing any of its properties, was destined to spread throughout the social body; its vocation was to become a generalized function. The plague-stricken town provided an exceptional disciplinary model: perfect, but absolutely violent; to the disease that brought death, power opposed its perpetual threat of death; life inside it was reduced to its simplest expression; it was, against the power of death, the meticulous exercise of the right of the sword. The Panopticon, on the other hand, has a role of amplification; although it arranges power, although it is intended to make it more economic and more effective, it does so not for power itself, nor for the immediate salvation of a threatened society: its aim is to strengthen the social forces-to increase production, to develop the economy, spread education, raise the level of public morality; to increase and multiply. How is power to be strengthened in such a way that, far from impeding progress, far from weighing upon it with its rules and regulations, it actually facilitates such progress? What intensificator of power will be able at the same time to be a multiplicator of production? How will power, by increasing its forces, be able to increase those of society instead of confiscating them or impeding them? The body of the king, with its strange material and physical presence, with the force that he himself deploys or transmits to some few others, is at the opposite extreme of this new physics of power represented by panopticism; the domain of panopticism is, on the contrary, that whole lower region, that region of irregular bodies, with their details, their multiple movements, their heterogeneous forces, their spatial relations; what are required are mechanisms that analyse distributions, gaps, series, combinations, and which use Rethinking Architecture 346 instruments that render visible, record, differentiate and compare: a physics of a relational and multiple power, which has its maximum intensity not in the person of the king, but in the bodies that can be individualized by these relations. At the theoretical level, Bentham defines another way of analysing the social body and the power relations that traverse it; in terms of practice, he defines a procedure of subordination of bodies and forces that must increase the utility of power while dispensing with the need for the prince. These disciplines, which the classical age had elaborated in specific, relatively enclosed places-barracks, schools, workshops-and whose total implementation had been imagined only at the limited and temporary scale of a plague-stricken town, Bentham dreamt of transforming into a network of mechanisms that would be everywhere and always alert, running through society without interruption in space or in time. It programmes, at the level of an elementary and easily transferable mechanism, the basic functioning of a society penetrated through and through with disciplinary mechanisms. At one extreme, the discipline-blockade, the enclosed institution, established on the edges of society, turned inwards towards negative functions: arresting evil, breaking communications, suspending time. At the other extreme, with panopticism, is the disciplinemechanism: a functional mechanism that must improve the exercise of power by making it lighter, more rapid, more effective, a design of subtle coercion for a society to come. The movement from one project to the other, from a schema of exceptional discipline to one of a generalized surveillance, rests on a historical transformation: the gradual extension of the mechanisms of discipline throughout the seventeenth and eighteenth centuries, their spread throughout the whole social body, the formation of what might be called in general the disciplinary society. This regulation is broadly similar to a whole series of others that date from the same period and earlier. In the Postscript he abandoned the idea, perhaps because he could not introduce into it the principle of dissymetry and prevent the prisoners from hearing the inspector as well as the inspector hearing them. Obviously, it was political in earlier periods, too, such as during the Roman Empire. Of course I did not mean to say that architecture was not political before, becoming so only at that time. I only meant to say that in the eighteenth century one sees the development of reflection upon architecture as a function of the aims and techniques of the government of societies. One begins to see a form of political literature that addresses what the order of a society should be, what a city should be, given the requirements of the maintenance of order; given that one should avoid epidemics, avoid revolts, permit a decent and moral family life, and so on. In terms of these objectives, how is one to conceive of both the organization of a city and the construction of a collective infrastructure? I am not saying that this sort of reflection appears only in the eighteenth century, but only that in the eighteenth century a very broad and general reflection on these questions takes place. If one opens a police report of the times-the treatises that are devoted to the techniques of government-one finds that architecture and urbanism occupy a place of considerable importance. Vitruvius was reinterpreted from the sixteenth century on, but one can find in the sixteenth century-and no doubt in the Middle Ages as well-many considerations of the same order as Vitruvius; if you consider them as reflections upon. The treatises on politics, on the art of government, on the manner of good government, did not generally include chapters or analyses devoted to the organization of cities or to architecture. The Republic of Jean Bodin does not contain extended discussions of the role of architecture, whereas the police treatises of the eighteenth century are full of them. What I wish to point out is that from the eighteenth century on, every discussion of politics as the art of the government of men necessarily includes a chapter or a series of chapters on urbanism, Rethinking Architecture 348 on collective facilities, on hygiene, and on private architecture. Such chapters are not found in the discussions of the art of government of the sixteenth century.
