Rizatriptan

Others who reject the major scares may find themselves in the grip of the panic over mobile phones or microwaves buy rizatriptan 10mg visa. Everybody is now more careful about what they eat or drink generic 10mg rizatriptan with mastercard, more reluctant to take medication, more aware of the need to take precautions against pathogenic forces, of whose existence they were unaware only a few years ago. Whatever their individual proclivities and prejudices, nobody is immune from the consequences of more than a decade of health scares. Doctors overwhelmed by an influx of patients in the grip of the latest health scare usually blame ‘the media’ for inflaming anxieties with ‘sensational’ headlines and ‘scaremongering’ television documenta- 28 HEALTH SCARES AND MORAL PANICS ries. Politicians complain of public complacency if people appear not to follow government health warnings and of over-reaction if they panic and, for example, suddenly refuse to buy British beef. Surveying the damage wrought on British agriculture—and the balance of trade—a week after his parliamentary statement on the supposed BSE-nvCJD link, health minister Stephen Dorrell declared in exasperation in a Radio Four interview that ‘it’s not the cows that are mad, it’s the public’ (quoted in Lang 1998). But the mad cow panic did not begin on the farms or in the butchers’ shops or supermarkets. It began among the scientists, spread to the politicians and was amplified in their interactions with the media, which transmitted it to the public. Nobody was better placed to dampen down the panic than Dorrell, yet his statement served only to exacerbate the anxieties that devastated farmers in Britain and beyond. The history of the major scares confirms that they did not originate in spontaneous outbreaks of public anxiety. They each started among doctors and scientists who themselves became alarmed, either at the emergence of a new disease (Aids, nvCJD), or the recognition of a new risk factor (front sleeping, MMR, the Pill). In the absence of any effective treatment for any of these conditions, doctors sought to raise public awareness of them, in the belief that this was the only means of prevention. The scares took off when doctors’ own anxieties led them to turn to their contacts with government and the media to generate wider publicity around the focus of their concerns. A number of factors have encouraged medical and scientific experts to project their anxieties into the public realm. One is the wider crisis of medical confidence in tackling the ‘modern epidemics’ of coronary heart disease and cancer, now that the threat of infectious diseases has receded. In the 1970s and 1980s, the recognition that effective treatments for these conditions remained elusive led to a swing towards health promotion in the cause of prevention, the subject of the next two chapters.

These fractures are often associated with intra-abdominal or retroperitoneal injuries 10mg rizatriptan fast delivery. A haematoma in the posterior mediastinum is often seen around the thoracic fracture site cheap 10mg rizatriptan fast delivery, particularly in the anteroposterior view of the spine and sometimes on the chest radiograph requested in the primary survey. If there is any suspicion that these appearances might be due to traumatic aortic dissection, an arch aortogram will be required. Fractures in the thoracic and lumbar spine are often complex and inadequately shown on plain films.

The inability to produce an effective cough impairs the clearing of secretions and commonly leads to atelectasis. The loss of lung compliance contributes to difficulty in breathing and leads to a rapid exhaustion of the inspiratory muscles. Abnormal distribution of gases and blood (ventilation-perfusion mismatch) also occurs in the lungs of tetraplegic patients, producing further respiratory impairment. Regular chest physiotherapy with assisted coughing and breathing exercises is vital to prevent atelectasis and pulmonary infection. Respiratory function should be monitored by measuring the oxygen saturation, vital capacity, and arterial blood gases. Bi-level support is preferable to continuous positive airway pressure (CPAP) and may avoid resorting to full ventilation.

Spatial neglect, with or without anosognosia, may also occur, particularly with right-sided lesions pro- ducing a left hemiparesis. Pure motor hemiparesis may be seen with lesions of the internal capsule, corona radiata, and basal pons (lacu- nar/small deep infarct), in which case the face and arm are affected more than the leg; such facio-brachial predominance may also be seen with cortico-subcortical lesions laterally placed on the contralateral hemisphere. Crural predominance suggests a contralateral paracentral cortical lesion or one of the lacunar syndromes. Brainstem lesions may produce diplopia, ophthalmoplegia, nys- tagmus, ataxia, and crossed facial sensory loss or weakness in addition to hemiparesis (“alternating hemiplegia”). Hemiparesis is most usually a consequence of a vascular event (cerebral infarction). Tumor may cause a progressive hemiparesis (although meningiomas may produce transient “stroke-like” events). Transient hemiparesis may be observed as an ictal phenomenon (Todd’s paresis), or in familial hemiplegic migraine which is associated with mutations in a voltage-gated Ca2+ ion channel gene.
