In some individ- is presumed, the cardiac investigation may remain uals, 2–10% according to different authors [3, 4], the limited. Finally, making the correct diagnosis means The anterior circulation can be subdivided into choosing the appropriate secondary prevention. Large-vessel disease suggests an M1 occlusion with or without carotid occlusion and is associated with a rather unfavorable 2. Other etiology intracranial pressure and subsequent subfacial, uncal and transtentorial herniation.

The artery is subdivided into the M1 segment, leading to an ipsilateral fixed mydriasis and the contra- from which start the deep perforating lenticulostriate lateral cerebral peduncle is compressed against the cere- arteries, the M2 segment, corresponding to the seg- bellar tentorium, leading to ipsilateral corticospinal ment after the bifurcation into superior and inferior signs, such as Babinski’s sign and paresis (Kernohan divisions, and the M3 segment, including the insular notch). Early recognition of frontal, prefrontal, precentral, central sulcus, anterior patients at risk enables the medical team to propose a parietal, posterior parietal, angular and temporal arter- hemicraniectomy for selected patients, a treatment ies, with important variations in their territories. As collateral networks are highly variable, an of the lower limbs are less involved than the face and occlusion of the same artery at the same place may arms. The patient is usually awake or presents mild partial brachiofacial sensitive loss (mainly tactile and drowsiness or agitation, particularly with a right discriminative modalities), transient conjugate ipsilat- infarct. Cognitive signs are always present: in the case eral eye and head deviation and aphasia (aphemia or of a left lesion, aphasia, and most of the time global, Broca aphasia) frequently associated with buccolin- ideomotor apraxia.

As we shall see in a moment muscle relaxant triazolam purchase mefenamic 250 mg with amex, these are very uncomfortable questions spasms esophagus problems discount mefenamic uk, but new technological developments suggest that increasingly they will have to be addressed spasms thoracic spine cheap mefenamic 250 mg with amex. Where people seek licensed treatment, centres should bear in mind the following factors: (a) their commitment to having and bringing up a child or children; (b) their ability to provide a stable and supportive environment for any child produced as a result of treatment; (c) their medical histories and the medical histories of their families; (d) their health and consequent future ability to look after or provide for a child’s needs; (e) their ages and likely future ability to look after or provide for a child’s needs; (f) their ability to meet the needs of any child or children who may be born as a result of treatment, including the implications of any possible multiple births; 101 102 J. McHale (g) any risk of harm to the child or children who may be born, including the risk of inherited disorders or transmissible diseases, problems during pregnancy and of neglect or abuse; and (h) the eVect of a new baby or babies upon any existing child of the family. They reXect also the background to treatment services provided under the legislation, which may take several years and ultimately still be unsuccessful. None the less, with the technological developments such as screening during pregnancy that we have today, far more information is now available as to the health/viability of the fetus. An obvious explanation is that such a duty should be imposed in a situation in which, were reproduction to take place, the resultant child would suVer some form of demonstrable harm after birth, and that such a ‘harm’ should be avoided. The direct ‘harm’ in the form of a disability which falls upon the child may also be accompanied by further harms, for example, the parents may be aVected by the birth of the child. Take the example of a couple who discover that they are at a very high risk of passing on a degenerative incurable disorder but who want to go ahead and try to conceive a child. This option is likely to be increasingly available in the future, as evidenced in the report on prenatal genetic testing of the Advisory Commit- tee on Genetic Testing (2000). But the couple may object to this – for example, they may have ethical/ religious objections to the destruction of the embryo or they may want to simply take the risk of going ahead in the hope that in their particular case Is there a duty not to reproduce? What of a situation in which they are aware of the risk that ‘harm’ may arise, but they argue that the disorder is a late-onset disorder, as a consequence not mani- festing itself for many years. She admits that there are diYculties in attempt- ing to deWne a ‘minimally satisfying life’: Conceptions of a minimally satisfying life vary tremendously among societies and within them. De rigueur in some circles are private music lessons and trips to Europe, whereas in others providing eight years of schooling is a major accomplishment. But there is no need to consider this complication at length here because we are concerned only with health as a prerequisite for a minimally satisfying life. While this may be regarded as an unsatisfactory criterion in that in some cultures debilitating conditions may be the norm, Purdy suggests that this objection can be circumvented by saying that parents ought to try to provide for their children health that is normal for that culture, even though it may be inadequate if judged by some outside standard. She states that such a position would still justify eVorts to avoid the birth of children at risk for Huntington’s disease and other serious genetic diseases in all societies (Purdy, 1996: p. If the couple at risk of bearing a severely handicapped child make the decision to go ahead, then who precisely will bear the cost of care and of medical treatment if the risks attendant upon handicap materialize? The ‘welfare’ mother may decide to go ahead and have a child, but the consequent costs of bringing the child into the world are likely to fall upon the State in such a situation – housing, medical treatment and the fact that the woman may be unable to enter the workforce, at least for some time, due to child-care commitments. While some ‘harms’ and some ‘costs’ may be identiWed, does this lead us inexorably to the conclusion that persons should be held to be under a duty not to reproduce? Some may think that conception and birth where there is a risk of those harms/costs arising may be undesirable, but does this ever really equate with imposing a duty not to reproduce, and in particular, backing that duty up through some recognition of legal liability? First, he suggests that few of those conditions would make the life of a child so horrible that its interests would have been better served had that child never been born. Secondly, Robertson argues that because a woman’s reproductive interest is generally very strong, there would need to be compelling criteria to override it, and factors such as saving money would not generally be adequate. She suggests that there are other ways in which reproduc- tive desires may be satisWed, including adoption and the use of new reproduc- tive technologies. She comments that other arguments for having children, such as wanting the genetic line to be continued, are not particularly rational when it brings a sinister legacy of illness and death.
