The drug is incor- the particular food; after boiling, the corks were sealed down porated into DNA in place of adenine. In an age before bacteriology, Appert did not other DNA building blocks. But, because the virus utilizes known as appertization—preserved the food. Appert later set the host’s genetic machinery, stopping the viral replication up his first bottling plant at Massy, south of Paris, in 1804. The French navy successfully used Appert’s products in Another tact for antiviral drugs is to block a viral 1807, and in 1809 Appert was awarded the 12,000-franc prize. This approach has been successfully covery, which he did in his 1810 work The Art of Preserving exploited by the drug acyclovir.

The tissue from affected patients has not been able to infect other animals or cell cultures and electron microscopy has not identified viruses purchase 0.25mg digoxin mastercard. More recent attempts using polymerase chain reaction (PCR) have demonstrated a wide array of findings quality 0.25mg digoxin, but no consistent picture, with CMV, HSV1, and EBV variably implicated. Rogers and col- leagues reported elevated levels of antibodies to a glutamate receptor (GluR3). They, and others, hypothesized that these antibodies could be highly neurotoxic. This led to a very complex hypothesis concerning the unihemispheric nature of RS. They pro- posed that there was a focal disruption of the blood–brain barrier that permitted GluR3 antibodies to interact with the glutamate receptors. Theorizing that if these antibodies could be eliminated, patients would improve, they treated a number of patients with plasmapheresis. The initial patient, and many others, responded initi- ally to this therapy with a decrease in seizures and improved function. However, over time repeated pheresis did not maintain this improvement and children deteriorated. This theory evokes an extensive lymphocytic infiltration by CD8 killer T cells. There is an extensive astroglial reaction, microglial activation, and cytolysis. CLINICAL ASPECTS Although RS is considered a disorder of childhood and one that affects only a single hemisphere, there have been reported instances of Rasmussen-like conditions that have begun in adulthood or that have involved both hemispheres. Classically, sei- zures begin in the early school years, with a range of onset from the second year of life to mid-teens. The initial seizure can be partial, generalized, or even an episode of status epilepticus. Seizures then typically evolve over time to produce a multifocal or unilateral condition of epilepsia partialis continua that is seen in slightly more than half of individuals with RS. The progression of a seizure is quite different from the well-understood Jacksonian march. Instead, one sees the clinical manifestations of separated areas of cortex firing independently. One can see the foot jerk, then the shoulder, then the thigh, then the hand, and then the face, with no contiguous march along the homunculus. It can almost be visualized as a popcorn effect: suddenly a seizure pops from one area, then another. This is also not like polymyoclonus, because the clonic activity can remain active in one area, but be rhythmically clonic at a different frequency in another area of the body. Another, somewhat less common presentation involves the basal ganglia and one can see expressions of dystonia and choreoathetosis in the setting of RS as well. Invariably, the process continues, resulting in hemiplegia or hemiparesis, homonymous hemianopia and functional deterioration. Neuroimaging has shown considerable utility because over time some degree of atrophy becomes appar- ent. Recent work has suggested that one can assess a hemispheric ratio from MRI studies to determine the degree and rate of atrophy of the hemisphere, with some evi- dence that most of the atrophy occurs in the first year of the disease. However, there is huge variability in RS and some individuals present with extensive atrophy at the time of their first seizure while others display a much slower course of progression. Other newer modalities may be useful, including magnetic resonance spectroscopy (MRS) in which N-acetyl-aspartic acid (NAA), a marker of neuronal death or injury, has been shown to be decreased beyond what would be expected based simply on atrophy. Other modalities such as diffusion-weighted imaging may also be helpful in the future. At best, it would show slowing over the affected hemisphere with multifocal spikes. At worst, because it can create doubt of the diagnosis, seemingly independent discharges can be seen bilaterally. With careful analysis, large asymmetries are usually apparent, and the spike from the truly abnormal hemisphere can often be seen to be leading the contralateral spike by milliseconds.

In a similar vein best 0.25mg digoxin, Sarah Nettleton argued that the ‘fallacy of empowerment’ was revealed by the fact that health promotion was invariably oriented towards the least powerful people in society (Nettleton 1995:238) digoxin 0.25mg otc. A number of commentators noted the origins of the ‘healthy cities’ projects in ‘paternalistic and cynical’ ‘community development’ programmes developed by the British colonial office in the 1950s to contain potential unrest, suggesting that establishment concern about preventing inner city revolt after a series of riots in the early 1980s provided the impetus behind community health initiatives (Farrant 1991; Peterson, Lupton 1996). Critics also focused on the potential for discrimination and containment that lay behind concepts of ‘community’. They observed that ‘participation’ often had a token character, which co- opted people into the existing power structure while giving them no real power in making decisions. Thus, while espousing a rhetoric of radical social change, in practice the activists of the new public 80 THE POLITICS OF HEALTH PROMOTION health operated as professionals implementing government policies of an essentially conservative character. While delegates to conferences in exotic international locations endorsed revolutionary declarations, supporters of the new public health at home sought to use these as a lever to press the government into adopting similar policies. A number of domestic influences, emerging more or less directly out of the experience of the previous Labour government, also encouraged the new public health movement. The first was the controversy over ‘health inequalities’ that ran through the 1980s—and remains an issue under New Labour today. In response to growing concern among radical social policy academics about increasing income differentials and their impact on health under the Labour governments of the 1970s, in 1977 health minister David Ennals set up a working group chaired by Sir Douglas Black, president of the Royal College of Physicians. By the time the group had completed its report—in April 1980—the government had changed and Mrs Thatcher was so hostile to the report’s call for a redistribution of resources and a re-orientation of health services to tackle the problems of poverty that it was effectively suppressed (Black 1980). The resulting furore ensured an even bigger readership when The Black Report was briskly published by Pelican (Black 1982). It was re-issued in 1988, together with an extensive update by Margaret Whitehead and an introduction by two members of the original working group, as Inequalities in Health (Townsend, Davidson 1988). The issue of increasing inequalities in income and in indicators of health became a rallying cause for radical critics of the Conservative government in the 1980s, keeping ministers under pressure to bring forward some initiative in this area. In the course of the 1980s a number of influential individuals and agencies encouraged the development of the government’s health promotion policy. The chief medical officer Donald Acheson produced a report recommending an enhanced role for ‘public health doctors’ and also endorsed the WHO approach to monitoring progress in public health by setting targets (Acheson 1988). In 1985 the Kings Fund and the Health Education Council organised a ‘study tour’ to investigate health promotion in North America; a team closely identified with the new public health issued an enthusiastic endorsement of the WHO strategy on their return (Robbins 1987). The following year another multi-disciplinary committee sponsored by the Kings Fund, with the brief to chart progress since Owen’s 81 THE POLITICS OF HEALTH PROMOTION Prevention and Health in 1976, produced a report with the suggestive title The Nation’s Health (Smith et al. This report also welcomed the WHO declarations and chastised the British government for its tardiness in meeting these targets. In its discussion of priority areas, strategies and targets, lifestyles and preventive services, it closely anticipated both the form and substance of the Health of the Nation documents. In the second ‘new and completely revised’ edition in 1991, the authors distinguished between the ‘tradition of limited government responsibility for health and welfare’ of which they disapproved, and the ‘modern, international movement in public health’ with which they strongly identified (Jacobson et al. They further welcomed the emphasis on health promotion in the new GP contract, recognising that this offered ‘new opportunities for developing public health practice’. While key aspects of the new public health agenda attracted powerful supporters in the medical and political establishments, in 1987 its activists launched the Public Health Alliance as a new ‘policy and pressure group’. Based in Birmingham, the alliance aimed ‘to bring together voluntary and community groups, professional associations, local authorities, trade unions and individuals to promote and defend the public health in the UK’ (Scott-Samuel 1989:33). According to Alex Scott-Samuel, like most of the leading figures in the alliance a public health doctor, its most important goal was to make a reality of ‘the principles behind the WHO Health For All strategy: the reduction of inequalities, intersectoral collaboration, primary health care and above all, community participation’ (Scott-Samuel 1989:35). The decisive weakness of the alliance resulted from the wider demise of the left: following the government’s victory over the miners in 1984–85 and Labour’s third consecutive general election defeat in 1987, left- wingers became increasingly isolated and marginalised in all areas of British society, including health. The resulting problem for the alliance’s approach was that its aspirations for ‘community participation’ acquired the character of a fantasy, whereas the dependence of public health professionals on the state remained all too real. In practice, the radical ideals of ‘Health For All’ were rapidly subordinated to the pragmatic imperatives of government health policy. The emergence of The Health of the Nation revealed the balance of forces determining public health policy and the limitations of the radical critique. Kenneth Clarke, as health 82 THE POLITICS OF HEALTH PROMOTION minister, and Donald Acheson, as Chief Medical Officer, both encouraged the evolution of the Kings Fund’s The Nation’s Health into the government’s The Health of the Nation.
