Structures above the tentorium are innervated by the ophthalmic division of the V cranial nerve buy generic priligy 60 mg on-line, whilst structures below the tentorium are innervated by C2 and C3 purchase 30mg priligy fast delivery. Cerebellar lesions usually cause pain posteriorly order priligy 90 mg fast delivery, and pain from occipital lobe lesions is felt anteriorly. However, because of a contribution from the caudal nucleus of V nerve, pain from upper cervical spine or posterior fossa can also be referred to the front of the head. Chronic renal failure may be associated with headache, emesis, and left ventricular failure. Many cases of bacterial meningitis suffer headache for months after the initial illness. It tends to be symmetrical, have a particular distribution (bifrontal, bioccipital, and nuchal), be of mild to moderate intensity, to have a stable intensity, to get worse as the day progresses, to lack features of migraine, and is often of high frequency (sometimes daily). It responds to reduction in stress, psychotherapy, environmental manipulation, alcohol, tranquillisers, etc. Sufferers (migraineurs) have been characterised as ‘anxious and neurotic’, but, whilst they do suffer an excess of anxiety and depression (probably more than other headache sufferers: Fleminger, 2009b, p. Rasmussen (1992) found that people with tension headache rather than migraine had high neuroticism scores on the Eysenck Personality Inventory. Indeed, previous descriptions of migraineurs as being particularly ‘neurotic’ may have been due to confinement of studies to clinic samples. Migraine with aura is more likely to be familial than is migraine without aura, but the likelihood of a latter case having a similarly affected close relative is increased nonetheless. The risk of a child developing migraine is, respectively, 45% and 70% if one or both parents have the disorder. Being pregnant may relieve migraine and two-thirds of cases improve with physiological menopause, the opposite number worsening with surgical menopause. The same phenomenon can be induced in animal studies by applying a strong solution of potassium. The wave may be preceded by a brief hyperaemic phase, possibly the cause of the lights that occur during an aura. Digitolingual paraesthesias (cheiro-oral syndrome) are a common part of the aura – numbness and pins and needles start in the fingers of one hand and extend into the arm and face, especially the nose and mouth area ipsilaterally; this usually follows the visual disturbance but uncommonly occurs without it. Teichopsia consists of visual hallucinations, especially of battlements, and is characteristic of migraine. Delirium may complicate an attack: there may be different combinations of dysphasia, agnosia, apraxia, amnesia, temporal lobe phenomena (e. Disturbed body image may occur at any stage of an attack – bodily components seem bigger (e. Pain is severe and throbbing or non-throbbing, and often arises early in the morning. Most attacks last less than a day and those lasting more than 72 hours are referred to as migraine status. The patient tends to lie down in a dark room (photophobia), may vomit, or faint if standing. The resolution phase is associated with fatigue, irritability, scalp tenderness, depression or euphoria. Pain may be felt in the face and is then often misdiagnosed as being due to sinus problems. Migraine attacks may be accompanied by psychiatric symptoms and sufferers may have increased rates of affective and anxiety disorders, nicotine dependence, and alcohol or illicit drug abuse or dependence. The lifetime prevalence of anxiety disorder and major depression has been estimated at 54% and 34% respectively in migraine patients (27% and 10% in controls respectively). Migraine with aura is associated with an increased risk of ischaemic stroke, migraine angina, as well as other ischaemic vascular events such as myocardial infarction, the risk varying by vascular risk factors. However, the same individual may experience attacks of either of these types and even an aura without headache (migraine equivalent or acephalgic migraine). In older cases without headache the term late-life migraine accompaniment may be used. Seizure activity may be precipitated by the aura of migraine, in which case valproate may be useful as an anticonvulsant and migraine prophylaxis. If the migraine sufferer is depressed, amoxapine or trazodone may be useful because of their high affinity for serotonin receptors. Botulinum toxin has also been used for this purpose (when attacks last for at least 15 days in every month): injections are given in forehead, sides of neck, and back of neck. Telcagepant, a new calcitonin gene-related peptide receptor blocking drug, does not (unlike triptans) cause vasoconstriction, is probably as effective as the triptans for migraine prophylaxis. Persistence of signs lasting over 1 week or evidence on a scan of cerebrovascular accident is termed migrainous infarction: to make the diagnosis, the infarction must occur during a typical attack of migraine with aura; the usual infarct involves a wedge of posterior occipital lobe; and risk factors include young, female, smoking, and anovulant use. Chronic migraine (transformed migraine) is the term used for attacks that increase quickly in frequency over at least a three-month period. Some, but not all, may be due to over-treatment (rebound headache) and such cases need to be detoxified very slowly. Familial hemiplegic migraine (rare, heterogeneous, autosomal dominant, chromosomes 19p13, 2q24) is associated with transient hemiparesis (with sensory, visual, or language dysfunction) preceding headache. Other types of ‘migraine’ are ophthalmoplegic (headache plus diplopia) and retinal (attacks of monocular scintillations, 3130 scotomata, blindness, and headaches) migraine. There is often a migraine history and one-quarter experience a virus-like illness in the weeks before onset. There are a variable number of episodes of varying fleeting neurological deficits (incl. Cluster headache (migrainous neuralgia): This may be due to a disorder of the hypothalamus. It usually affects above one eye , though sometimes it may affect a cheek or even occur close to an ear. A partial Horner’s syndrome (minor degree of ptosis and meiosis), transient or permanent, may persist between attacks. If the condition is expected to last for a few weeks, corticosteroids can be used. Treatment of an attack may involve oxygen (100%, 7-12 litres/minute: vasoconstrictive effect and reduces release of calcitonin gene-related peptide), sumatriptan (subcutaneous [6 mg] or nasal), zolmitriptan (nasal or oral), dihydroergotamine, nasal lidocaine, corticosteroids, and various other procedures, e. Percutaneous radiofrequency trigeminal rhizotomy may be useful for chronic intractable cluster headache. Also, stimulation of the occipital nerves with electrodes implanted in the suboccipital region may be useful for chronic intractable cases. A family history, aura, photophobia or phonophobia, nausea or vomiting will favour migraine. Of course there is nothing to stop someone with one of these headache types having, say, a tumour. Secondary (symptomatic) cluster headache can be due to many intracranial disorders, e. The diagnosis should be considered if there is no periodicity to the attacks, if there is some headache between attacks, if response to treatment is unsatisfactory, and if there are neurological signs (apart from miosis and ptosis). There may be a dull, tight or cramping sensation in the occiput or generally, building in severity until orgasm or abruptly starting with orgasm.

As a Invest in research designed to improve and condition of reimbursement, public payers track progress in addiction prevention, and private insurance companies should be treatment and disease management and to find a cure for addiction. Create a unified national institute focused on substance use and addiction, recognizing the overarching disease of addiction rather than continuing the focus on different manifestations of the disease--tobacco, alcohol, other drug use-- and including the risky use of all addictive substances. Include in the research portfolio addiction involving behaviors other than substance use, and focus on the causes, correlates, consequences, interventions, policies and possible cures for all manifestations of the disease. The portfolio of the institute also should include health conditions resulting from risky use and addiction and other conditions which increase the risk of developing addiction. In many but not all cases, it involves the use of nicotine, † alcohol and other drugs. Addiction involving these substances typically originates with use in adolescence when the brain is still developing 2 and is more vulnerable to their effects. If untreated, it can become a chronic and relapsing condition, requiring ongoing professional 3 treatment and management. Although there has been an evolution in scientific understanding of the disease, public attitudes and health care practice have not kept pace with the science. Terms used to describe different levels of substance use and addiction’s many forms lack precision, obscuring important differences in the use of addictive substances and the nature and severity of the illness and complicating our ability to treat it effectively. The term addiction also has been used in reference to compulsive behaviors involving eating, gambling and other activities that affect the brain’s reward system and which may develop independent of or in combination with other manifestations of addiction. This report, however, focuses only on addiction involving nicotine, alcohol and other drugs. Use of these Advances in neuroscientific research, including substances can result from an existing brain animal studies and brain imaging, demonstrate dysfunction; use also can alter the structure and clearly that addiction is a primary and often function of the brain, dramatically affecting * 4 8 chronic disease of the brain.

Rather than take on Dr Pearson and rebut his evidence purchase priligy with mastercard, he was heard to complain that he was caught up in a medical war which had nothing to do with his client or his case buy priligy. The chemical spillage in the van Lorraine was driving had had a long-term deleterious effect upon her health and had sensitised her to a number of other substances order 60mg priligy mastercard. The most important witness for the prosecution was Dr Monro, who gave evidence about chemical sensitivity. If the defence were able, or wanted, to show that there was no long-term deleterious effect from chemical exposure, then they would have to dispute the diagnostic capability and the professional authority of Dr Monro. The court was not told that the programme had been sponsored by Health-Watch, organised by Caroline Richmond and had starred Dr Pearson. Her rented surgery space in a private London hospital was brought up, as if such a practice was somehow peculiar. She was cross examined about the role of her son, who worked as an administrator at the Breakspear Hospital, as if this reflected badly upon her professional competence. Sitting in the well of the court, Lorraine Taylor could see that few, if any, of these issues were relevant to her case. Deposits of toxins which after six years have probably become lodged in fatty tissue, are difficult and expensive to measure. There is a bitter unwillingness amongst many professionals, legal as well as medical, to explore the organic base of chemical sensitivity. The easy diagnosis of psychiatric disorder is one which has dogged women down the centuries whenever they have complained about damage inflicted upon them by more powerful social individuals or groups. Although the chemical spillage might have caused her to be ill, it was only because she was idiosyncratic and vulnerable to such things. Her case, and her illness, were the risks which had to be taken, if we are to live with the benefits of modern chemical science. The judge awarded minimal costs to Lorraine Taylor for the personal expenses which she had incurred during her search for compensation. These came to half of the amount which her employers had offered her after accepting the immediate liability of the spillage and the short-term effect it had upon her health. In awarding these costs, the judge was at least making it clear that he did not consider the action had been frivolous. In the summer of 1989, Penny Brohn, the founder of the Bristol Cancer Help Centre, was invited to appear on a television programme in Birmingham. Brohn found reasoned debate impossible with Marks, who threw loaded questions at her which pre-empted logical answer. Marks was utterly unwilling to accept that there was a place for the Bristol Cancer Help Centre in the care of cancer patients. These practitioners were, according to him, denying patients proper medical attention, and withholding orthodox medical care from them. I have taken part in some debates in my time, but I realised that this was in another league. Penny Brohn had read about the setting up of the Campaign Against Health Fraud, and a colleague had told her that Bristol was on its target list. A couple of months after the television interview, a physicist working at the Bristol Royal Infirmary told Brohn about a talk that Michael Baum was to give at the Radiotherapy Department. In the bar after the meeting, Penny Brohn approached Baum and began a discussion with him. She realised then that Baum was years out of date with what was happening at the Centre. He did not even know that one of the founders, Dr Alec Forbes, had left some years ago. Nor did he know that the Centre was working in close cooperation with general practitioners and caring, in the main, for people who had already had orthodox treatment. He continued to refer to alternative treatments on every occasion, and as he was a cancer specialist, he continued to lambast those institutions which gave alternative cancer care. From the meagre beginnings of a small self-help group, they had established the most successful complementary cancer care centre in Britain. Penny Brohn had written two books which had publicised what had become known as the Bristol Programme, but the Centre had never quite managed to achieve the level of publicity of the years following its opening in 1980. The second programme would chart the growth of the Centre through the eighties and examine its contemporary practices. With another three years to go on the study, no one at the Centre paid much attention to these results. Around the time that they received the interim results, Penny Brohn began to notice inexplicable changes in the attitude of the film makers who visited the Centre. The earlier friendly co-operation began to give way to an embarrassed secretiveness. Within a short time of filming, the director appeared to come under pressure to change the nature of the film and to present it, not simply as a film, but in tandem with a combative discussion programme. When the programme producers eventually told Penny Brohn that they had decided to change the format of the programmes, she was concerned. After all, these programmes were meant to show the constructive work of the Centre and celebrate its tenth anniversary. Brohn was originally assured that any studio discussion would be more of an informal conversation between people in armchairs and not a structured debate. I agreed to allow these programmes to be made on the basis of a strict understanding between us all that any discussion programme would cover an investigation into where complementary 5 medicine had gone and how it had developed during the previous ten years. She was adamant that the Centre would only go ahead with the programmes if there was an agreement on the kind of debate which would follow them. She told Salmon she had seen studio discussions turn into bun fights and made it clear that she would not take part in such an event. As August passed and September began, Penny Brohn became increasingly concerned about the focus of the films. The producer seemed to talk to her less and they obviously did not share the same confidence with which they had begun. When the producer, David Henshaw, visited the Centre one day, Penny Brohn cornered him. Brohn knew this programme had in the past organised debates between antagonistic parties. When it was clear that the original agreement had been violated, Brohn and the other administrators at the Centre began to think seriously about trying to pull out. When the programme researcher visited her with the kind of questions which were to be asked, she knew that the debate would be exactly as she had feared. The debate would go ahead and the presenter would say that the Centre had declined to appear. The administrators at Bristol were under the impression that both studies were begun in 1986.
Most cases of thrombosis are due to acquired extrinsic problems (surgery purchase priligy 90 mg free shipping, cancer discount 60mg priligy free shipping, immobility cheap priligy online, obesity, ‘economy class syndrome’), but some are due to predisposing conditions, known collectively as thrombophilia (e. Procoagulants include: • The use of adsorbent chemicals, such as zeolites and other haemostatic agents, to seal severe injuries quickly. Thrombin and ﬁbrin glue are used surgically to treat bleeding and to throm- bose aneurysms. Warfarin (and related coumarins) and heparin are the most commonly used anticoagulants. Aspirin, clopidogrel, dipyridamole and ticlopidine are among the anti-platelet agents. A newer class of drug, the direct thrombin inhibitors, are under development; some members (such as lepirudin) are already in clinical use. Focus on: anaemia Anaemia is deﬁned as a qualitative or quantitative deﬁciency of haemoglobin, which may lead to hypoxia (lack of oxygen) in organs. The three main ways in which anaemia may arise are: • excessive blood loss (acutely, such as a haemorrhage, or chronically through low-volume loss, e. Anaemia is the most common disorder of the blood; there are several kinds, produced by a variety of underlying causes. Anaemia may be classiﬁed by a ‘kinetic’ approach, which involves evaluating the production, destruction and loss of red blood cells, or a ‘morphologic’ approach, based on red blood cell size. Anaemia often goes undetected; signs and symptoms can be related to the anaemia itself or to the underlying cause. Types of anaemia Microcytic anaemia is primarily a result of a failure or deﬁciency of haemoglobin synthesis, which may be caused by several aetiologies: • Haem synthesis defect, for example iron-deﬁciency anaemia and anaemia of chronic disease (more commonly presenting as normocytic anaemia). Red blood cells often appear hypochromic (paler than usual) and microcytic (smaller than usual). Iron-deﬁciency anaemia is caused by insufﬁcient dietary intake or absorption of iron, or by loss of blood, for example bleeding lesions of the gastrointestinal tract. Worldwide the most common cause of iron-deﬁciency anaemia is parasitic infestation (hookworm, amoebiasis, schistosomiasis and whipworm). Macrocytic anaemia is deﬁned as one in which the red blood cells are larger than normal. Megaloblastic anaemia is the most common cause of macrocytic anaemia, caused by a deﬁciency of either vitamin B12 or folic acid (or both). Deﬁciency in folate and/or vitamin B12 may result from either inadequate intake or malabsorption. Pernicious anaemia is caused by a lack of intrinsic factor, which is required to absorb vitamin B12 from food (see below). Macrocytic anaemia can also be caused by removal of the functional portion of the stomach, such as during gastric bypass surgery, leading to reduced vitamin B12 and folate absorption. Macrocytic anaemia can be further divided into ‘megaloblastic anaemia’ and ‘non- megaloblastic macrocytic anaemia’. Pernicious anaemia is a megaloblastic anaemia, caused by a deﬁciency of vitamin B12; it is associated with both haematopoietic and neurological disorder. In the stomach, vitamin B12 is bound to one of two B12 binding proteins present in gastric juice; in the less acidic environment of the small intestine, these proteins dissociate from the vitamin. It is then bound by intrinsic factor, produced by the parietal cells of the gastric mucosa; the B12–intrinsic factor complex is speciﬁcally bound by epithelial receptors in the ileum, where the vitamin B12 is then absorbed. The most common cause for impaired binding of vitamin B12 by intrinsic factor is autoimmune atrophic gastritis. Autoantibodies are directed against parietal cells, which atrophy and cannot make intrinsic factor, and consequently cannot transport vitamin B12. Less frequently, loss of parietal cells may simply be part of a widespread atrophic gastritis of non-autoimmune origin, such as that frequently occurring in elderly people affected with long-standing chronic gastritis (including H. Treatment of pernicious anaemia has traditionally involved the parenteral delivery of vitamin B12 to ensure absorption. Oral replacement is now an accepted route, using large doses of vitamin B12, 1–2 mg daily. Normocytic anaemia occurs when the overall haemoglobin levels are decreased, although red blood cell volume remains normal. Treating anaemia • Mild to moderate iron-deﬁciency anaemia is treated by iron supplementation with ferrous sulphate or ferrous gluconate. A diagnosis of iron deﬁciency may indicate other potential sources of iron loss, such as gastrointestinal bleeding from ulcers or colon cancer. Blood transfusions for anaemia are generally to be avoided due to adverse clinical outcomes, but in severe, acute bleeding, transfusions of donated blood are often lifesaving. Focus on: angiogenesis Angiogenesis is the physiological growth of new blood vessels from pre-existing vessels. It is a normal process in growth and development, as well as in wound healing, but is also a fundamental step in the transition of tumours from a dormant to a malignant state. Receptor activation gives rise to a signal transduction cascade that leads to gene activation and diverse biological responses, including cell differentiation, proliferation and matrix dissolution, thus initiating a process of mitogenic activity critical for the growth of endothelial cells, ﬁbroblasts and smooth- muscle cells. This has been demonstrated to be a major contributor to angiogenesis, increasing the number of capillaries in a given network. These are protein growth factors that promote angiogenesis (as demon- strated by mouse knock-out studies). There are four identiﬁed angiopoietins, Ang1–4; in addition there are a number of proteins that are closely related to angiopoietins. This proteolysis allows the endothelial cells to escape into the interstitial matrix, as seen in sprouting angiogenesis. Angiogenesis as a therapeutic target Angiogenesis may be a target for combating diseases in which there is either poor vascu- larisation or abnormal vasculature. These proteins mainly originate as speciﬁc fragments to pre-existing structural proteins such as collagen or plasminogen. Angiogenesis represents an excellent thera- peutic target for the treatment of cardiovascular disease, namely the production of new collateral vessels to overcome the ischaemic insult. However, despite the large num- ber of pre-clinical trials in animal models of cardiac ischaemia, no therapy designed to stimulate angiogenesis in underperfused tissue has yet become viable in man. White adipose tissue is vascularised, much like a tumour, and growth of adipose tissue is highly dependent on the building of new blood vessels (angiogenesis). Recent studies with obese mice models have shown that proapoptotic peptide, directed against blood vessels, results in decreased food intake and signiﬁcant fat loss. Besides an adequate supply of calcium, a close cooperation is required between these two types of cell. Mature osteoblasts synthesise type 1 collagen, osteocalcin, cell attachment proteins (thrombospondin, ﬁbronectin, bone sialoprotein, osteopontin), proteoglycans and growth-related proteins. Vitamin D stimulates synthesis of alkaline phosphatase, matrix and bone-speciﬁc proteins.
The ‘welfare’ mother may decide to go ahead and have a child buy priligy no prescription, but the consequent costs of bringing the child into the world are likely to fall upon the State in such a situation – housing order priligy 90mg without prescription, medical treatment and the fact that the woman may be unable to enter the workforce cheap priligy generic, 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. She also states that while a desire to bear children who physically resemble oneself is understandable although basically narcissistic, its fulWlment cannot be guaranteed even by normal reproduction. It could be argued, however, that some of those persons whose opportunity to conceive naturally was, prima facie, limited by a duty not to reproduce, could still conceive through the use of artiWcial reproduc- tive technologies. One alternative is to say to such a couple, ‘You will be penalized if you reproduce naturally and the ‘‘harm’’ in the form of the disability materializes. However, you do have the option of pre-implantation genetic diagnosis, and this oVers you an alterna- tive; therefore we are not limiting your reproductive choices, your pro- creative liberty, to any great extent at all. Before we go down this road we need to address serious and fundamental questions, not simply about an individual’s choice, but also about society’s attitude to the disabled members of our community. Furthermore, the recognition of a duty not to reproduce may be regarded as unacceptable because it may mean that a person will in eVect be virtually forced to discover their genetic status should they want to reproduce. This may itself have other consequences with regards to the use of that genetic information – for example, with regards to insurance and employment prospects in years to come. It is worth noting that the Council of Europe (1996), in the Convention for the Protection of Human Rights and Dignity of the Human Being with Regard to the Application of Biology and Medicine, provides that: Everyone is entitled to know any information collected about his or her health. Say that there are certain, perhaps very limited, situations in which individuals may be wrong in seeking to reproduce – so wrong that they should actually be held to be under a duty. If the bodily intrusion associated with compulsory contraception is relatively minor, it may be that compelled contraception in rare cases could be justiWed, though such policies would be highly controversial. Some would argue that the a moral duty may be recognizable, but as Robertson has noted, that ‘does not mean that those duties should have legal standing’ (Robertson, 1994: p. To hold a woman or a couple liable for their decision to have a child, despite what are substantial warnings regarding the risks of such a course of action, might also constitute a breach of the European Convention on Human Rights – for example, of Article 12, the right to marry and found a family. There are fundamental questions regarding the privacy of the individual in relation to their home and family life under Article 8 which would arise in such a situation. It should also be noted that the Council of Europe Convention on Human Rights and Biomedicine provides in Article 11 that ‘Any form of non-discrimination against a person on grounds of his or her genetic heritage is prohibited’. We need of course to bear this in mind, particularly in view of the fact that those provisions of the European Convention of Human Rights are now justiciable in the English courts since the Human Rights Act 1988 came into force in October 2000. Secondly, would this be a duty involving state sanctions, enforceable, for example, through the criminal law or will it be limited to civil liability, perhaps in the form of an action brought by the child consequent upon birth? How do you inform people that they are under such a legal duty, and that if they reproduce without Wnding out their genetic status, there may be legal consequences? Do we have to put up notices in railway stations, general medical practitioners’ surgeries and night clubs warning people that if they conceive unwittingly, some form of legal liability may result? After all, with the pace of technological developments such as gene therapy, the serious degenerative late-onset disorder may be curable by the time that infant reaches adulthood. It is also the case that the practical diYculties of recognizing such a duty may also collide with another set of legal principles, namely, membership of the European Union. Cases such as that of Blood send out a powerful message – European regulation is changing the face of health care today, and single jurisdiction regulation may indeed be inadequate in health care law. McHale Repaying the state An alternative is to say to the individual/couple: ‘Yes, you may reproduce in a ‘‘risky’’ situation, but if the ‘‘harm’’ does arise and, as a consequence, the state incurs costs, then you will be liable to pay that cost’. This solution, however, can be seen as undesirable, in that at the very least it is discriminatory between those with Wnancial resources and those without. Secondly, an action could be brought by the child, for example, claiming that the parents’ actions resulted in their birth in a disadvantaged or disabled condition. The Congenital Disabili- ties Civil Liability Act 1976 provides that an action may be brought by a child born with a disability as a result of an occurrence which aVects either of its parents in their ability to have a normal healthy child, or an occurrence which aVects the mother during pregnancy and either mother and child during birth. While there is the possibility that fathers may be sued under the Congenital Disabilities Civil Liability Act 1976, the mother is excluded from liability with the exception of the situation where she has been involved in a road traYc accident. Questions as to what constitutes reasonable parental conduct, what good suing a parent does the disabled child, may apply with equal force to both parent. The real issue in the case was, however, the claim by Mary McKay that the doctor owed her a duty of care when she was in utero, which involved advising her mother as to the desirability of having an abortion, which advice the mother said she would have accepted. First, if the duty of care to the fetus involved imposing a duty on the doctor – albeit indirectly – to prevent the child’s birth, the child would have a cause of action against her mother if she refused to have an abortion. Secondly, the Law Commission in their Report on Injuries to Unborn Children (1974), which had rejected the wrongful life claim, had been of the view that such a claim would impose intolerable burdens on the medical profession, because of subconscious pressure to advise abortion in doubtful cases through fear of action for damages. He was of the view that provided that the defendants gave a balanced explanation of risks involved in alleged pregnancy, including risk of injury to the fetus, the doctor could not be expected to do more. Finally, the Court of Appeal held that section 4(5) of the Congenital Disabilities (Civil Liability) Act 1976 excluded liability in wrongful life claims, a point on which all the members of the Court of Appeal in this case agreed. Section 4(5) of the 1975 Act provides that the Act applies to all births after its passing, and in respect of any such birth, it replaces any law in force before its passage whereby a person could be held liable to a child in respect of disabilities with which it might be born. The policy arguments against their acceptance, as outlined in relation to the judgments of the Court of Appeal in this case, have been echoed by academic commentators (Lee, 1989; Fortin, 1987). For example, Mason and McCall Smith have suggested that ‘we favour abandoning the principle of ‘‘wrongful life’’ in favour of diminished life; we can then look not at a comparison, whether it be between the neonate’s current existence and non-existence or with normality, but rather at the actual suVering that has been caused’ (Mason and McCall Smith, 1999: p. They comment further that, ‘This carries the practical advan- tage that the courts can understand and accommodate this form of damage, which allows for a distinction to be made between the serious and slight defect’ (Mason and McCall Smith, 1999: p. Presumably in this situation the couple would not be liable, but here an action may then be brought against the clinician, precisely the type of action rejected in McKay. The diYculties that arise in the context of the competent adult are magniWed still further when we consider mentally incompetent persons and the teenage pregnancy. The consequences of a duty not to reproduce are such that it is unlikely that the courts would be willing to impose such a duty, at present, upon the parents. This has on occasions, as we have seen in relation to enforced Caesarean sections, led to an area of private life being increasingly subject to regulation. None the less, while these are uncomfortable arguments, and while there are considerable problems in the legal enforcement of such duties, there is no doubt that the changing face of genetics will force us to address them. What is important is that such arguments should be addressed in advance by clini- cians, lawyers and philosophers alike, rather than allowing ourselves to be precipitated into dealing with them in the courtroom.
